[002] Not applicable. DESCRIPTION FIELD
[003] This description refers to balers, including the formation, wrapping, and knot of the finished bales. GROUNDS FOR DESCRIPTION
[004] In various agricultural or other configurations, it may be useful to form bales from growing material (or another plant), such as hay or corn straw. Various machines or mechanisms can be used to collect material (for example, from a heap along a field) and process it in bales. The bales formed can be of various sizes and, in certain applications, may exhibit generally rectangular cross sections (ie, or others). In order to create rectangular bales, for example, a square baler can travel along a heap of cut crop material by collecting the material in a baling chamber. A reciprocating plunger or other mechanisms can then encompass the growing material in bales.
[005] Known balers may include several cVcogpVq * qw “cVcfqtgu” + swg cVco qu hctfqu cVcpfq qu twine twine around the bales. In typical configurations, knots and related interlacing management devices can be arranged in a row extending laterally across the top (or bottom) of a baling chamber. A twine loop for each tie on a baler can be fed by the interlacing management devices to wrap around a bale when the bale is being formed. When the plunger moves the bale backward through the baling chamber, the backward movement of the bale through (and then out of) the baling chamber pulls the string from spools to accommodate the size of the bale's growth. When the bale is fully formed, each tying mechanism can then tie its respective string mesh in order to secure the string to the bale. Such tied meshes can help the bale retain its overall shape and integrity once it is ejected from the baler.
[006] Various problems can arise from known balers, as balers handle (for example, form, wrap and eject) bales. Among these problems, the complexity, size, and weight of various knotters can complicate the manufacture, operation, and maintenance of the baler. For example, the relatively large size of typical knots can limit the total number of knots that can be provided for a given baling chamber. As known knotters are typically configured to tie only one twine at a time, the number of twine twines to tie bales from a given baling chamber can be appropriately limited. In addition, because of the complexity of typical knotters, knotters can also be subject to frequent damage and breakage. This can result in incomplete or inadequate tying of the finished bales as well as significant downtime and maintenance expense for the affected baler. DESCRIPTION SUMMARY
[007] A baler and method are described to form and wrap bales of crop material.
[008] According to one aspect of the description, a baler may include a baling chamber, and a cultivation movement device, such as a reciprocating plunger, to compress the cultivation material into a bale within the baling chamber. . A baling chute can be oriented outside the baling chamber. A sheet of wrapping material can be wrapped around a wrapping frame supported by the baling chute to form a sleeve of the wrapping material. Once formed within the baling chamber, the bales can be ejected from the baling chamber into the baling trough and moved through the wrap frame in order to be wrapped with the sleeve.
[009] In certain implementations, the baling chamber can be a blind baling chamber with a rear wall and a side member. The bales can be ejected from the baling chamber by moving the side member to urge the bales from the baling chamber into the baling trough. Prior to the ejection of the bale from the baling chamber, a portal of the baling chamber can be moved to provide an ejection passage for the bale from the baling chamber to the baling trough.
[0010] In certain embodiments, a baling chute can be oriented along one first side of the baling chamber and another baling chute can be oriented along a second side of the baling chamber. A side member of the baling chamber can be oriented on a second side of the baling chamber when the cultivation movement device compresses cultivation material for a first bale, and can be moved to the first side of the baling chamber to urge the first bale formed for a baling trough. With the side member oriented on the first side of the baling chamber, a second bale can be formed. The side member can then be moved to the second side of the baling chamber to urge the second formed bale onto the other baling chute.
[0011] In certain embodiments, the wrapping material sleeve can be configured with an inlet end and an outlet end, with the outlet end being further away from the baling chamber than the inlet end. When the bale passes through the sleeve, a front portion of the bale can engage the sleeve at the outlet end such that the bale pulls the wrapping material away from the baling chamber. The portion of the wrapping material that rolls up the bale can be configured to be separated from the sleeve, such that when the bale is removed from the baling chute, the portion of the wrapping material remains wrapped in the bale and the sleeve remains supported through the baling chute.
[0012] In certain embodiments, the baling chamber may include a movable rear wall, with the cultivation movement device being configured to compress cultivation material against the movable rear wall to form a burden. During compression of the growing material, the rear wall can be moved based on one or more of a predetermined compression distance for the growing material and a predetermined target pressure for the growing material.
[0013] According to another aspect of the description, a baler can include a baling chamber with a side member configured to move laterally within the baling chamber. The first and second baling rails can be oriented outside the baling chamber along the first and second side sides, respectively, of the baling chamber. One or more ejection actuators can be configured to eject bales formed on the first and second baling chutes, respectively, by moving the side member from the second and first side sides of the baling chamber, respectively, to the first and second sides sides of the baling chamber, respectively.
[0014] In certain embodiments, a first wrapping device can be arranged along the first baling chute. The first wrapping device may include a support for retaining a sleeve of wrapping material in the first baling chute. When the first bale moves along the first baling chute, the first bale can pass through the sleeve of the wrapping material, such that a portion of the wrapping material rolls up the first bale.

[0017] The sequence describes one or more exemplary modalities of the disclosed baler and the related method, as shown in the attached figures of the drawings described briefly above. Various modifications of the exemplary modalities can be contemplated by a person skilled in the art, including the implementation of the method disclosed through a special purpose computer system that employs one or more processor devices and memory architectures.
[0018] As used cswk. “Wrapping material” rqfg kpfkect wo fg various types of materials used to retain bales of compressed plant material or to otherwise maintain the integrity (structural or otherwise) of the bales.

For example, a bale can be wrapped with string by knitting the string around the bale and, in certain cases, tying the stitches. Likewise, a bale can be wrapped with a net or wrapper sheet by applying the net or sheet over outer portions of the bale. In certain cases, wrapping a bundle can also include attaching wrapping material in place of the bundle. For example, attaching wrapping material to a bale, wrapping material can be laced on itself, tied or tied, heat welded or sealed, vibration-sealed, shrunk in place, expanded, fastened with clasps, and so on .

[0020] As noted above, typical balers can wrap a bale with string meshes when the bale is formed in the baling chamber. Once the bale is fully formed, binders can tie the twine stitches to secure the twine around the bale. Bindings can be distributed laterally across the width of the baling chamber, such that each binder is on a single string loop around a formed bale.
[0021] Due to the relatively large size of known knotters, the total number of knotters that can be used for a particular baling chamber - and thus the number of string loops that can be tied to an associated bale - can be limited. Appropriately, typical balers may include only a limited number of knotters for each of the associated baling chambers. In combination with material strength limitations, this can limit the binding force that can be applied to a bale with twine and binders, which in turn can limit the amount of growing material that can be compressed into a particularly sized bale.
[0022] With typical baler designs, the complexity of the wrappers and the operations they perform can also introduce complications. For example, knots may tend to snag, jam, or break with some regularity when the string becomes entangled or growled within the knotter (and related systems). This can result in downtime for the baler, as well as significant maintenance and replacement costs. Ties can also be as heavy as they are expensive, which can contribute to increased baler weight and increased manufacturing cost.
[0023] The disclosed baler and the baling method can address these and other problems. In certain embodiments, after a bale has been formed in a baling chamber, the bale can be ejected from the baling chamber in a baling trough. In a square baler, for example, an reciprocating plunger can cyclically squeeze crop material collected inside the baling chamber to form a bale with a generally rectangular (for example, square) cross section. The bale can then be ejected from the baling chamber to a baling chute, where the bale can be wrapped with wrapping material before being ejected from the baling chute into the field.
[0024] In certain embodiments, the baling chamber of the baler may not include binders or other wrapping (and tying) devices, such that bales ejected from the baling chamber may be uninvolved bales. One or more wrapping devices can be oriented around the baling chute to wrap a bale when the bale rests on (or moves through) the baling chute. In certain embodiments, bales ejected from the baling chamber can be partially uninvolved bales. For example, in certain embodiments, a formed bale can be partially wrapped with string or other wrapping material while still inside the baling chamber, then ejected into the baling trough for additional baling.
[0025] In certain embodiments, baling rails can be oriented along one or more of the lateral sides of the baling chamber. For example, in a square baler with a plunger that reciprocates along a path from front to back inside the baling chamber (or with another cultivation movement device), a single baling chute can be oriented along one side side (ie, right or left) of the baling chamber. In other embodiments, a pair of baling rails can be provided, one on each side of the baling chamber. Once an uninvolved (or partially uninvolved) bale has been formed in the baling chamber by the plunger, an actuator can propel the bale sideways from the baling chamber to the particular baling chute for wrapping and ejection into the field. This can contrast with known balers, where bales are usually extruded from an open rear end of the baling chamber.
[0026] In certain embodiments, a sleeve of wrapping material can be supported on (or around) a baling chute with a gzVtgokfcfg cdgttc * iutq fi. woc gzVtgokfcfg “fg gntracla”) fc ocpic oriented towards the baling chamber and an open end (ie umc gzttgmifcfg fg “ucifc” + fc mcpic qtigptcfc qrqutc § eâmatc fg baling from the input end when the bale is moved. outside the bale chamber for the baling trough, the bale can pass to the sleeve through the inlet end. When the bale leaves the sleeve at the outlet end, a portion of the wrapping material can be engaged by the bale, such that the portion of wrapping material continues with (for example, adheres to) the bale, so when the bale is ejected from the baling chute into the field, the bale can be appropriately wrapped. for example, it can be supported in a support wrap in a baling chute such that a bale being ejected from the baling chamber passes into an opening in the sleeve.When the bale passes through the sleeve to the outlet end u A portion of the bale can engage a loose portion of the wrapping material (for example, a free edge of the wrapping material at the outlet end of the sleeve) such that the plastic sheet is pulled by the movement of the bale to properly wrap the bale . When the bale leaves the sleeve, the plastic sheet surrounding the bale can be pulled from the largest sleeve (for example, in a pre-existing hole, in a cut formed by a cutting device (not shown), and so on. onwards) so as to remain wrapped around the burden.
[0027] Other wrapping materials and wrapping devices may also be possible. For example, rolls of wrapper net or plastic sheet can be rotated (or otherwise moved) around a bale in the baling trough (or elsewhere) such that the bale is wrapped with successive meshes of the wrapper net. or plastic sheet. Similarly, spools of twine can be provided in the baling chute (or elsewhere), in order to wrap the bale with twine meshes. As appropriate, these meshes can then be tied with a tie device or other mechanism.
[0028] In certain embodiments, a bale can be indexed along the baling chute when a wrapping device winds successive loops of wrapping material around the bale. This can result in a spiral of material to wrap around the bale. For example, when a bale is pushed along a baling chute (for example, by another bale being ejected from the baling chamber), a wrapping device can provide a continuous loop feed, wrapping net, plate plastic, or other wrapping movement. The movement of the bale beyond the wrapping device can appropriately cause a relatively opposite movement of this mesh feed in the bale. Thus, as long as indexing and mesh feeding continue, the bale can be wrapped with a spiral of the wrapping material.
[0029] In certain embodiments, a side member of the baling chamber can be moved laterally in order to eject bales from the baling chamber into the baling chute. A movable side wall of the baling chamber, for example, can be actuated by a hydraulic piston (or other actuator) in order to push, pull, or otherwise propel a bale from the baling chamber. The movement of a side member to eject bales from the baling chamber can also propel the bales through (or in addition to) a particular wrapping device in order to facilitate the wrapping of the bales in the baling chute. For example, a movable sidewall can urge a bale (directly or indirectly, including through another bale) to pass from a baling chamber to a baling trough, then pass through a sleeve of wrapping material that is supported in the baling chute.
[0030] In certain embodiments, a portal can be provided, which can open to allow the passage of bales from the baling chamber to the baling trough. For example, a first side member of a baling chamber (for example, another movable side wall) can be lifted by a hydraulic cylinder (or another actuator) in order to allow a second side wall (for example, as noted above) push a bale out of the baling chamber.
[0031] In certain embodiments, a single side member can be used to separately propel bales on either of the two (or more) baling chutes. For example, a baling chamber may include (or otherwise be associated with) a movable side member, and a baling trough may be provided on each of two side sides of the baling chamber. With the side member (for example, a movable side wall) on a first side of the baling chamber, a first bale can be formed. The side member can then be moved from the first side of the baling chamber to a second side of the baling chamber in order to urge the first bale onto a first of the baling troughs. The side member can then be held on the second side of the baling chamber while a second bale is formed, then moved back to the first side of the baling chamber in order to urge the second bale onto a second of the baling troughs.
[0032] In certain embodiments, the baling chamber can be a blind baling chamber. For example, in a square baler with a reciprocating plunger a rear wall of the baling chamber can be provided, against which the plunger can compress growing material to form a bale. As additional cultivation material is introduced for compression, the rear wall can be moved progressively backwards in the baling chamber (or otherwise away from the plunger) in order to accommodate the growing burden. In certain embodiments, the rear wall of a baling chamber can be movable.
[0033] The position of a movable rear wall of a baling chamber can be controlled in several ways during baling (and wrapping) operations. In certain implementations, a rear wall can be controlled by moving the rear wall a predetermined distance for each piston cycle. For example, where the plunger compresses successive “flqequ” fg growing material for a forming bale, the rear wall can be moved a particular distance backwards (ie away from the plunger) for each flake. As this distance can correspond with a particular amount of compression of flakes of a nominal size, the fkuVâpekc rqfg ugt qdugtxcfc eqoq woc “fkuVâpekc fg eqortguu« q ”. In order to ensure proper compression of the flakes, an appropriate compression distance may be less than the average thickness (front to back, relative to the baling chamber) of the flakes.
[0034] In certain implementations, the position of the rear wall of the baling chamber can be controlled based on a target pressure. For example, where the rear wall is actuated by a hydraulic cylinder, a hydraulic accumulator (or other device or system) can be used to maintain a particular target pressure for the cylinder. (It will be understood that such a target pressure may be part of a target pressure range.) An appropriate target pressure (or range), for example, can correspond with a desired amount compression of the growing material for the bales in formation.
[0035] In certain implementations, the position of the rear wall of the baling chamber can be controlled based on both a predetermined compression (and another) distance and a predetermined pressure (or pressure range). For example, for each cycle of a reciprocating piston the rear wall can be moved initially by a predetermined compression distance. This can, for example, allow the initial compression of flakes against a relatively rigid wall (i.e., the rear wall, as held in position based on the compression distance). When the plunger advances (for example, when a cam that drives the plunger approaches an orientation with greater mechanical advantage), a predetermined target pressure can then be maintained on the rear wall, with the rear wall moving (for example, backwards ) as appropriate to ensure the proper resistive pressure for the plunger when the plunger advances. This may allow, for example, the flakes to be compressed by a particular amount, so as to form an appropriately dense bale.
[0036] Several exemplary modalities discussed below may include particular square balers. However, it will be understood that the enhancements disclosed here can be used with respect to a variety of balers and types of balers.
[0037] Referring now to FIG. 1, a large square baler 20 of known configuration is shown. As the baler 20 moves across a field (for example, as towed by vehicle 22 through a connection 22a) and encounters a heap or other arrangement of material (not shown), a collection set 26 can collect the material and move the even for a housing 24 for processing on a bale 28. In certain configurations, a plunger (not shown in FIG. 1) can successively compress flakes of growing material inside a baling chamber 30 until the bale 28 has been completely formed . Before the formed bale 28 is ejected from the rear of the housing 24, and while the bale 28 is still inside the baling chamber 30, the bale 28 can be wrapped with the string (or other material) and the string tied by a tie (not shown in FIG. 1).
[0038] Referring further to FIG. 2, an improved example baler 40 is depicted, baler 40 being configured to eject bales formed onto the side of baler 40 as an alternative (or in addition) to ejecting bales formed from the rear of baler 40. (For clarity of presentation of various internal mechanisms, the housing of the baler 40 is not represented in the various figures.) The baler 40 is generally supported for traveling through a field by the wheels 42 mounted to a chassis 44. A collection set 46 for collecting material of cultivation from a field is provided, which may be similar to collection set 26. Cultivation material collected by collection set 46 is routed up and back through baler 40 and formed into generally rectangular flakes 54. The flakes 54 are then compressed into a baling chamber 50 by an reciprocating plunger 48 to form a bale.
[0039] Several modalities discussed here can use an alternating motion plunger, such as plunger 48, to compress cultivation material within the relevant baling chamber. Other cultivation movement devices may additionally (or alternatively) be used. For example, an auger (not shown) can be used to feed cultivation material into a baling chamber and, in certain embodiments, compress the baling material into the baling chamber.
[0040] Baler 40 (or other similar balers) can also include one or more controllers 52. Controllers 52 can be configured as computing devices with associated processor devices and memory architectures, such as hydraulic, electrical or electro-hydraulic controllers , or otherwise. In this way, controllers 52 can be configured to perform various control and computational features with respect to baler 40 (and other machinery). An example location for controllers 52 is shown in FIG. 2. However, it will be understood that other locations are possible including other locations on baler 40 or several remote locations (for example, on a tow vehicle (not shown), at a remote located control station (not shown), and so on). Controllers 52 may be in electronic, hydraulic, or other communication with various other baler 40 systems or devices (or machinery). For example, controller 52 may be in electronic or hydraulic communication with various actuators, sensors, and other devices within (or outside) baler 40, including various devices associated with baling chamber 50 and related mechanisms. Controller 52 can communicate with other systems or devices (including other controllers) in a number of known ways, including via a CAN bus (not shown) from baler 40 or a tow vehicle, without ropes, in a hydraulic manner, or other way.
[0041] In the embodiment shown in FIG. 2, the reciprocating piston 48 moves in a cyclic front-to-back path (i.e., generally from left to right, in FIG. 2) as driven by a rotating eccentric arm 56 (or multiple eccentric arms (not shown )). A feeder assembly successively distributes flakes 54 of cultivation material (e.g. flakes 54a shown in FIG. 2) to the plunger path 48, near the front portion of the baling chamber 50. The cyclic movement of the plunger 48 pushes these flakes 54 back to the baling chamber 50, compressing the flakes 54 for a growing burden.
[0042] In certain embodiments, as represented in FIGS. 2 to 5, a hydraulic cylinder (or other) 38 can be configured to operate the eccentric arm 56, in order to move the piston 48. In these embodiments, the eccentric arm 56 can be rotated by only a portion of a complete revolution, as cylinder 38 is alternated between extension and retraction operations. In certain embodiments, a gearbox alternatively (or in addition) can be provided to operate the eccentric arm 56. For example, a gearbox can be configured to receive rotary energy from a vehicle energy starting shaft 22 ( for example, how it can extend through connection 22a), and use the energy received to rotate the eccentric arm 56. In modalities with a gearbox, the eccentric arm 56 can be rotated through a complete revolution. Other devices or systems alternatively (or in addition) can be used to move an eccentric arm (for example, eccentric arm 56) or a cultivation movement device (for example, plunger 48). For example, in certain embodiments, a screwdriver (not shown) or another mechanism can be used to move a plunger into and out of a baling chamber.
[0043] A baling chamber can be connected (or otherwise defined) in a variety of ways. As shown, chamber 50 is generally connected on the left side with a side wall 66 and on the right side with a portal 60. Still as shown, hydraulic cylinders 62 and 64, mounted to support structures 64 and 70, respectively, are configured to actuate the side wall 66 and the portal 60, respectively, in order to eject bales from the baling chamber 50. For example, as controlled by controller 52, and in coordinated synchronism with the plunger 48 and other baling components, the cylinder 68 can move sidewall 66 sideways through the baling chamber from left to right and from right to left. Similarly, cylinder 62 can move portal 60 up and down to open or close an ejection passage for a bale that has been formed in the baling chamber 50. In this way, a formed bale can be moved by side wall 66 and cylinder 68 through the opening of portal 60.
[0044] It will be understood that other configurations may be possible. In general, to eject bales formed from chamber 50, a side member of various designs can be moved laterally (or otherwise) by the baling chamber 50. In certain embodiments, the side member can be configured as a complete side wall of the baling chamber 50, as with the side wall 66. In certain embodiments, the side member can be configured in another way. For example, a mesh, mesh, grid, or other partial wall can be provided, which can also be moved laterally by the baling chamber by an actuator of various types. Similarly, a piston, plunger, or other side member can be provided, which may not sweep the entire length, height or width of chamber 50, but which can be acted on independently to eject a bale from chamber 50. In certain embodiments, a side member can be oriented on a side of the baling chamber 50 other than a side side of the baling chamber (e.g., a top, bottom or rear side of the chamber 110). In certain embodiments, various connections, rotation members or other actuating mechanisms can be used in place of cylinder 68 and support structure 76.
[0045] A portal can also be configured in several ways. In general, a portal can serve to retain a bale within the baling chamber 50 while the bale is being formed (and thereafter), as well as to release the bale formed from the baling chamber 50 when appropriate. A portal can be a knife portal such as the depicted portal 60, which moves up and down along a defined path to open or close an ejection passage for the bale. Alternatively (or in addition) a portal can be configured to slide laterally, forward, or backward with respect to baler 40, to swing open and closed in various ways, to fold or roll closed, and so on.
[0046] Still with reference to FIG. 2, a rear wall 72 of the baling chamber 50 provides resistance to the plunger so that several flakes 54 are compressed by the plunger 48 into a finished bale. An actuator, such hydraulic cylinder 74 is provided (for example, supported with respect to chassis 44 by a support structure 76), in order to control the performance of the rear wall 72. As discussed in more detail below, cylinder 74 (or another actuator) can control the rear wall 72 based on predetermined compression distances, compression pressures, or other factors.
[0047] Again, it will be understood that other configurations may be possible. As shown, as the rear wall 72 connects the baling chamber 50 opposite the plunger 48, the baling chamber 50 can be viewed as a blind baling chamber. Other types and configurations of a rear wall of the chamber 50 can be provided as an alternative to the rear wall shown 72. In certain embodiments, for example, the baling chamber 50 may not include a rear wall and therefore cannot be a blind chamber.
[0048] The various support structures 64, 70 and 76 for cylinders 62, 68 and 74 (or other support structures for other actuators) can be configured in a variety of modes. As shown, the support structures 64, 70, and 76 include welded metal tubing with the frame 44 of the baler 40 in order to rigidly support the cylinders 62, 68, and 74 with respect to the frame 44 and the baling chamber 50. Other arrangements are also possible.
[0049] One or more baling chutes can also be provided in baler 40, for receiving and wrapping bales that are ejected from the baling chamber 50. In the embodiment shown in FIG. 2, for example, a baling chute 82 is configured as a platform that is laterally adjacent to, and extends laterally away from, the right side of the baling chamber 50. Appropriately, a bale ejected through the right side of the chamber baling 50 in general can pass to baling chute 82 before being ejected from baler 40 into the field (or other location). As shown, the baling chute 82 is generally oriented horizontally, such that a bale resting on the baling chute 82 may tend to remain in the baling chute 82 in the absence of active ejection force.
[0050] Other configurations are also possible. In general, a baling chute can be configured as a variety of platforms or other support structures that are located adjacent to and outside a relevant baling chamber. The platform or other support structures of a baling chute can be configured to extend to various widths, laterally, away from the associated baling chamber. In certain embodiments, such a platform or support structure in general may be less wide than the nominal width of an associated bale (or bale chamber). In this way, a bale that is completely ejected from a baling chamber into a baling trough can extend laterally beyond the laterally outer edge of the baling trough. In certain embodiments, a baling chute can be oriented obliquely with respect to the horizontal, such that a bale in the baling chute can be polarized by gravity away from (or to) the relevant baling chamber. In certain embodiments, as discussed in more detail below, multiple baling chutes can be provided for the particular baling chamber.
[0051] A baling chute in general can support, or otherwise be associated with, a wrapping device for wrapping bales in the baling chute with wrapping material (and, in certain embodiments, tying or otherwise securing the material to involve). Thus, even if a bale is in an uninvolved (or partially uninvolved) state when it is ejected from a baling chamber into a baling trough, the bale can still be involved before it is finally ejected from the baler ( for example, to the field, or to a rear cart). As shown in FIG. 2, the baler 40 includes several sleeve supports 88 supported by the chassis 44. A sleeve 84 of wrapping material (e.g., plastic wrapping material) is supported on the supports 88, such that a bale moving from the chamber baling material 50 through the baling trough 82 passes through the sleeve 84 and is surrounded by the wrapping material of the sleeve 84. The sleeve supports 88 are shown as laterally oriented members in the baling trough 82 to hold the sleeve 84 in place in the baling chute 82 and retains the ends of the open sleeve 84 at the inner and outer side edges of the baling chute 82. Other configurations of the supports 88, the sleeve 84, and so on, may also be possible.
[0052] In certain embodiments, a device for wrapping other than a sleeve and sleeve support may be provided. In certain embodiments, for example, a ring or other device can be used to wrap wrapping material (for example, from rolls of wrapping material) around a bale in a baling trough. As shown in FIG. 3, for example, a roll 94 of wrapping material and the associated wrapping device (or other similar arrangement) can be provided as an alternative (or in addition) to the supports 88 and the sleeve 84 (or other wrapping configuration) ). The roll 94 of wrapping material can be supported on (or close to) the baling chute 82 in a variety of ways, and an associated device (not shown) can wrap material from the roll 94 around a bale in the chute. baling 82 so as to involve the burden.
[0053] In certain embodiments, string or similar material can be used as an alternative (or in addition) to sleeve 84 (or other wrapping material configurations). As shown in FIG. 2, for example, a number of laces 92 (or other wrapping devices) can be provided. The cord (not shown) can be looped around a bale in the baling chute 82 and then tied with the binders 92 to secure the cord to the bale.
[0054] In certain embodiments, a wrapping device can wrap a bale in a baling chute with wrapping material when the bale is indexed through the baling chute. For example, when a bale is driven by a baling chute (for example, directly by a movable side member of a baling chamber, or indirectly by a movable side member pushing another bale against the bale in the baling chute) a wrapping can wrap the cord, wrapping net, plastic sheet or other wrapping material around the bale. Appropriately, when the bale in the baling chute moves beyond the wrapping device, the bale can be wrapped with successive spirals of the wrapping material.
[0055] Returning specifically to the depicted embodiment of baler 40, the various mechanisms noted above can cooperate cooperatively to form a bale in the baling chamber 50, eject the bale into the baling trough 82, wrap the bale, then eject the bale from baler 40. Referring again to FIG. 2, at the start of a baling cycle, the side wall 66 is oriented on the left side of the baling chamber 50 and the portal 60 is in a lowered configuration (and thus provides a second side wall for the baling chamber 50). The cylinder 74 is in an extended configuration, such that the rear wall 72 is located near the front of the baling chamber 50. As a number of initial flakes 54a are successively provided by the feeding mechanism, the reciprocating movement of the plunger 48 compresses the flakes 54a against the rear wall 72 to start forming a bale. In certain cases, an already formed bale 86a can now rest on the baling chute 82 within the sleeve 84.
[0056] As noted above, cylinder 74 and rear wall 72 can be controlled in a variety of ways to facilitate compression of flakes 54a by plunger 48. In certain implementations, controller 52 can direct cylinder 74 to move the wall rear 72 back into the baling chamber 50 by a particular distance for each piston cycle 48. For example, if a typical flake 54a is to be compressed by the plunger 48 to a front-to-back thickness of 1.5 inches in order to form an appropriately compressed bale in the baling chamber 50, the cylinder 74 can be actuated to move the rear wall 72 approximately 1.5 inches backward in the baling chamber 50 for each new flake 54a (and, appropriately, for each cycle of the plunger 48). As is also noted above, as this distance can be seen as the width at which a particular flake 54a can be compressed, it can be seen as a compression distance.
[0057] In certain implementations, the controller 52 can direct the cylinder 74 to provide a particular pressure to the rear wall 72 in order to resist the backward compressive movement of the piston 48. For example, if a particular compression pressure (ie , a target pressure) is necessary to properly compress a particular flake 54a (or set of flakes 54a) into a bale, cylinder 74 can be actuated to provide this pressure to the rear wall 72. In certain embodiments, an accumulator 78 (or similar device) can be provided to help maintain the appropriate target pressure with the cylinder 74.
[0058] In certain implementations, controller 52 can direct the cylinder to implement a combination of control based on distance and pressure. For example, at the beginning or before the start of a compression stroke of the plunger 48, cylinder 74 can be actuated to move the rear wall 72 backwards by a particular compression distance, a distance that in some way may be less than the expected (or target) thickness of a fully compressed flake 54a. After some time, cylinder 74 can then be used to maintain an appropriate target pressure (or pressure range) to resist the compression force of plunger 48 and to ensure proper compression of the current flake 54a (for example, even when cylinder 74 allows that the rear wall 72 moves backwards into the baling chamber 50).
[0059] As an advantage of combining control based on distance and pressure of the rear wall 72, a constant resistive pressure (or otherwise controlled) provided by cylinder 74 through the rear wall 72 can be applied against the movement of the plunger 48 only when the eccentric arm 56 is oriented to provide an improved mechanical advantage with respect to the movement of the plunger 48. For example, it will be understood that when the eccentric arm 56 that drives the plunger 48 is oriented in a vertical manner, relatively high torque must be applied to the eccentric arm 56 so as to provide a given amount of pressure on the plunger 48. Appropriately, the rear wall 72 can be moved back by a predetermined compression distance in order to provide relatively small resistance to the plunger 48 while the eccentric arm 56 of the plunger is close to its vertical orientation.
[0060] With reference to FIG. 6A, for example, an example configuration for driving eccentric arm 56 with a gearbox 58 is shown. (As shown in FIG. 6A, gearbox 58 can be arranged on baler 40 with baling chamber 50 to the right.) When gearbox 58 rotates eccentric arm 56 in a clockwise direction (from from the perspective of FIG. 6A), the eccentric arm 56 can move the plunger 48 (not shown in FIG. 6A) to compress a bale within the baling chamber 50. While the eccentric arm 56 is arranged within a particular angular range in Around or near a vertical orientation (for example, within range 56a) the rear wall 72 can be adequately controlled based on the compression distance. It will be understood that band 56a is provided as an example only, and that other eccentric arm guidance bands can be selected to correspond with distance-based control of the rear wall 72. Additionally, it will be understood that a similar control strategy can be employed in the modalities in which the plunger 48 is otherwise moved (for example, in modalities using a cylinder, such as cylinder 38 shown in FIGS. 2 to 5).
[0061] In contrast, as the eccentric advances to a horizontal orientation (for example, to move the plunger 48 back into the baling chamber 50), relatively less torque must be applied to the eccentric arm 56 in order to provide the same amount of pressure (or more) on the plunger 48. When the eccentric arm 56 advances to horizontal, therefore, the rear wall 72 can provide (through cylinder 74) a predetermined target pressure (for example, instead of a predetermined compression distance) thereby allowing the plunger 48 to strongly compress the flakes 54a against the rear wall 72 without requiring excessive torque on the eccentric arm 56.
[0062] With reference to FIG. 6B, for example, the example gearbox configuration of FIG. 6A is shown with the eccentric arm 56 having moved almost to a horizontal orientation. While the eccentric arm 56 is disposed within a particular angular band around or close to the horizontal orientation (for example, within the range 56b) the rear wall 72 can be controlled based on the target pressure, instead of the compression distance. It will be understood that band 56b is provided as an example only, and that other eccentric arm guidance bands may correspond with pressure-based control of the rear wall 72. Additionally, it will be understood that a similar control strategy can be employed in the modalities in which that the plunger 48 is moved in another way (for example, in embodiments using a cylinder, such as cylinder 38 shown in FIGS. 2 to 5).
[0063] In certain embodiments, other mechanisms can be controlled in various ways depending on the relative position of the plunger 48, the eccentric arm 56, and so on. In the embodiment shown in FIGS. 2 to 5, for example, cylinder 38 (or a similar cylinder) can be controlled with respect to the position of the eccentric arm 56, the position of the plunger 48, or the position or pressure on the rear wall 72. For example, as is also noted above, where the rear wall 72 has been moved a predetermined compression distance within the baling chamber 50, a relatively small amount of force may be required on the cylinder 38 to properly move the plunger 48. Appropriately, a relatively low pressure or low energy flow can be used by cylinder 38 to move eccentric arm 56 to compress cultivation material against the rear wall 72. When cylinder 74 is then used to provide a target pressure on the rear wall 72, greater force can be necessary to compress the relevant flake. Suitably, a higher pressure or greater flow of energy can be used by the cylinder 38 to move the eccentric arm 56.
[0064] Referring again to FIG. 3, when the baler 40 progresses along the field, the baling chamber 50 is gradually filled with a number of compressed flakes 54. As can be seen in FIG. 3, for example, the original flakes 54a (see FIG. 2) are approaching the rear of the baling chamber 50 even when new flakes 54b continue to be distributed for compression. When the baling operation progresses (that is, from FIG. 2 to FIG. 3), the rear wall 72 is moved farther and farther to the rear of the baling chamber 50 by the rear cylinder 76. As noted above, various types of control is possible for this backward movement, including control based on predetermined compression distances and control based on target pressures. In certain embodiments, particular compression distances or target pressures can be modulated depending on the bale formation progression (for example, depending on the current bale size, or the relative position of the rear wall 72 within the baling chamber 50).
[0065] Referring further to FIG. 4, the various flakes 54 were compressed into the baling chamber 50 in an uninvolved bale 86b. Suitably, cylinder 62 raises portal 60, thereby opening an ejection passageway 90 between the baling chamber and baling chute 82. Cylinder 68 then causes side wall 66 to push bale 86b through from the baling chamber 50 to the baling chute 82 for wrapping. As shown, for example, when the bale 86b is pushed from the baling chamber 50, the bale 86b passes to an inlet end 84d of the sleeve 84 of wrapping material, as supported by the sleeve supports 88, and thus is wrapped with wrapping material.
[0066] Where the previously formed bale 86a is already in the baling chute 82, as in the embodiment shown in FIG. 4, pushing bale 86b from baling chamber 50 into baling chute 82 causes bale 86a to be moved laterally from baling chute 82. In certain embodiments, this may additionally contribute to wrapping the previously formed bale 86a. As shown in FIGS. 2 and 3, for example, when bale 86b is fully supported by baling chute 82, the outer side edges of bale 86b can engage with the outer side edge 84a of sleeve 84 (i.e., it can engage with the wrapping material nearby of the outlet end of the sleeve 84). This engagement of bale 86b with the edge 84a (or other portion) of the sleeve 84 causes the bale 86a to pull material from the sleeve 84 when the bale 86a is pushed laterally out of the baler 40. Thus, the wrapping material of the sleeve 84 may involve the entire side width of bale 86a when bale 86a is ejected from the baling chute 82 and the baler 40.
[0067] As shown in FIG. 5, as the bale 86a falls from the baling chute 82, a portion 84b of the wrapping material of the sleeve 84 can detach from the sleeve 84 to maintain the enveloped state of the bale 86a. For example, a perforated seam can arrange the sleeve 84 to separate at the edge 84c when the bale 86a falls from the baling trough 82, and in this way allows the portion 84b to remain enveloped in the bale 86a. The edge 84c can then be arranged to engage with the outer side edge of the subsequent bale 86b. In certain embodiments, portion 84b of sleeve 84 can be separated from the rest of sleeve 84 in other ways, including with various cutting devices (not shown) or other mechanisms.
[0068] Still with reference to FIG. 5, due to the movement of the side wall 66 and the portal 60, the bale 86b was ejected from the baling chamber 50 to the baling chute 82 (and to the sleeve 84) and the previously formed bale 86a was ejected, in a completely involved, from the baling chute 82 to the field. The system can then be reset to the configuration of FIG. 1, in order to allow incoming flakes 54c to be compressed within the baling chamber 50 in another bale.
[0069] In certain embodiments, it may require more time to eject a bale from the baling chamber 50 to the baling chute 82 than to complete a front-to-back compression cycle with the plunger 48. Appropriately , in certain implementations, it may be useful to pause the operation of the plunger 48, or otherwise delay the compression of new flakes 54c within the baling chamber 50, during the ejection of a bale already formed from the baling chamber 50. embodiment shown in FIG. 5, for example, cylinder 68 first extends side wall 66 through the baling chamber to eject a bale, then retracts side wall 66 to its starting position. During this cycle, the movement of the plunger 48 can be arrested (or slowed) or incoming cultivation material (not shown) can temporarily be stored in another location (not shown) while the cylinder 68 operates to eject the bale 86b. Once the sidewall 66 is properly oriented, the operation of the plunger 48 to compress several incoming flakes can then be summarized.
[0070] In certain embodiments, a bale can be over-compressed within a baling chamber, such that the bale will expand in some way once the relevant compressive forces of the baling chamber have been removed. In certain embodiments, such excess compression may further facilitate the improved involvement of the relevant burden. With respect to the baler 40, for example, the plunger 48 and the rear wall 72 can cooperate with over-compressing the bale 86b, in the baling chamber 50, to a size that is somehow smaller than the ejection passage 90 or the support structures 88 and the sleeve 84. As a result, the formed bale 86b can be moved through the ejection passage 90 and into the sleeve 84 relatively easily, with little risk of the sides of the bale 86b improperly catching the sides of the passage 90, sleeve 84, support structures 88, and so on. Additionally, because of the excess compression, the bale 86b may begin to expand in some way once the compressive forces of the plunger 48 and the rear wall 72 have been removed. With proper synchronization, this expansion can be made to occur, at least in part, while the bale 86b is enclosed by the sleeve 84 (or otherwise being engaged by a wrapping device). In this way, because of the initial over-compression of the bale 86b, the bale 86b may tend to expand into the wrapping material of the sleeve 84 and thereby provide more secure engagement of the wrapping material with the bale 86b.
[0071] As is also noted above, in certain embodiments, multiple baling chutes can be provided. Referring further to FIG. 7, another example baler 100 is shown. (For the clarity of the presentation of various internal mechanisms, the housing of baler 100 is not shown in the various figures.) Baler 100 can be similar to baler 40 in several ways. For example, baler 100 is generally supported for traveling through a field by wheels 102 mounted to a chassis 104. A collection set 106 for collecting cultivation material from a field is provided, which may be similar to sets of collection 26 and 46. Cultivation material collected by collection set 106 is routed up and back through the baler 100 and formed into generally rectangular flakes 114. The flakes 114 are then compressed into a baling chamber 110 by a plunger reciprocating motion 108 to form a burden. Baler 100 may also include one or more controllers 112.
[0072] In the embodiment shown in FIG. 7, the reciprocating piston 108 moves in a cyclic front-to-back path (i.e., generally from left to right, in FIG. 7) as driven by a rotating eccentric arm 116. A feeder assembly successively distributes flakes 114 of cultivation material (for example, flakes 114a shown in FIG. 2) to the plunger path 108, close to the forward portion of the baling chamber 110. The cyclic movement of the plunger 108 pushes these flakes 114 back into the baling 110, compressing flakes 114 into a growing burden. In the embodiment shown in FIGS. 7 to 10, the hydraulic cylinder 118 can be used to move the eccentric arm 116. It will be understood that other arrangements can be used to move the eccentric arm 116, including a gear box similar to the gear box 58 of FIGS. 6A and 6B, an auger, or other mechanism.
[0073] As shown, the baling chamber 110 is generally connected laterally by a single movable side wall 120. Hydraulic cylinder 122, mounted to the support structure 124 is configured to actuate the side wall 120, in order to eject bales from of the baling chamber 110. For example, as controlled by controller 112, and in sync coordinated with plunger 108 and other baling components, cylinder 122 can move sidewall 120 sideways through the baling chamber from left to right and right to the left. In this way, the plunger 108 and side wall 120 can alternately eject bales formed into the right and left sides of the baling chamber 110.
[0074] It will be understood that other configurations may be possible. In general, to eject bales formed from chamber 110, a side member of various designs can be moved laterally (or otherwise) by the baling chamber 110. In certain embodiments, the side member can be configured as a complete side wall of the baling chamber 110, as with the side wall 120. In certain embodiments, the side member can be configured in another way. For example, a mesh, mesh, grid, or other partial wall can be provided, which can also be moved laterally by the baling chamber by an actuator of various types. Similarly, a piston, plunger, or other side member may be provided, which may not sweep the entire length, height, or width of chamber 110, but which may be acted upon independently to eject a bale from chamber 110. In certain embodiments, a side member can be oriented on a different side of the baling chamber 110 than a lateral side of the baling chamber (e.g., a top, bottom or rear side of the chamber 110). In certain embodiments, various connections, rotation members or other actuating mechanisms can be used in place of cylinder 122 and support structure 124.
[0075] In the embodiment shown in FIG. 7, no portal similar to portal 60 (see, for example, FIG. 5) is used to control an ejection passage for the release of a bale from the baling chamber 110. In certain embodiments, however, a various configurations can be used, including a portal similar to portal 60 of FIGS. 2 to 5.
[0076] Still with reference to FIG. 7, a rear wall 126 of the baling chamber 110 provides resistance to the plunger so that several flakes 114 are compressed by the plunger 108 into a finished bale. An actuator, such hydraulic cylinder 128 is provided (for example, supported with respect to chassis 104 by a support structure 130), in order to control the performance of the rear wall 126. As discussed above, with respect to cylinder 74 and the rear wall 72, cylinder 128 (or another actuator) can control rear wall 126 based on predetermined compression distances, compression pressures, or various other factors.
[0077] Again, it will be understood that other configurations may be possible. As shown, since the rear wall 126 connects to the baling chamber 110 opposite the plunger 108, the baling chamber 110 can be viewed as a blind baling chamber. Other types and configurations of a rear wall of the chamber 110 can be provided as an alternative to the rear wall shown 126. In certain embodiments, for example, the baling chamber 110 may not include a rear wall and therefore cannot be a blind chamber.
[0078] The various support structures 124 and 130 for cylinders 122 and 128 (or other support structures for other actuators) can be configured in a variety of modes. As shown, support structures 124 and 130 include welded metal tubing with frame 104 of baler 100 in order to rigidly support cylinders 122, and 128 with respect to chassis 104 and baling chamber 110. Other arrangements also are possible.
[0079] A plurality of baling chutes can also be provided in baler 100, for receiving and wrapping bales that are ejected from the baling chamber 110. In the embodiment shown in FIG. 7, for example, a baling chute 136 is configured as a platform that is laterally adjacent to, and extends laterally away from, the right side of the baling chamber 110. Appropriately, a bale ejected through the right side of the chamber baling material 110 can generally pass to baling chute 136 before being ejected from baler 100 into the field (or other location). Similarly, a baling chute 140 is configured as a platform that is laterally adjacent to, and extends laterally away from, the left side of the baling chamber 110. Appropriately, a bale ejected through the left side of the baling chamber 110 in general it can pass to the baling chute 136 before being ejected from the baler 100 into the field (or other location). As shown, baling chutes 136 and 140 are generally oriented horizontally, such that a bale resting on any of the baling chutes 136 and 140 may tend to remain in baling chutes 136 and 140 in the absence of active ejection force. (or inclination of baler 100). Other configurations are also possible, including configurations in which any of the baling chutes 136 and 140 can be oriented obliquely with respect to the horizontal. In certain embodiments, one or more of the baling rails 136 and 140 itself can be movable. For example, a hydraulic actuator (not shown) can be provided to tilt one of the baling chutes 136 and 140 away from the baling chamber 110 in order to encourage a bale in the baling chute 136 or 140 to slide from the chute 136 or 140.
[0080] As noted above, a baling chute in general can support, or be otherwise associated with, a wrapping device. Thus, if a bale is in an uninvolved (or partially uninvolved) state when ejected from a baling chamber into a baling trough, the bale can be wrapped in the baling trough before being ejected into the field ( or elsewhere). As shown in FIG. 7, the baler 100 includes several sleeve supports 146 and 148 supported by the chassis 104. The sleeves 138 and 142 of wrapping material (for example, plastic wrapping material) are supported, respectively, on the supports 146 and 148, as that bales move from the baling chamber 110 through the baling rails 136 and 140 pass through the sleeves 138 and 142, respectively, and are enveloped by the wrapping material from the sleeves 138 and 142. The sleeve supports 146 and 148 are shown as laterally extending members in the baling rails 136 and 140 to hold the sleeves 138 and 142 in place in the baling rails 136 and 140 and retain the ends of the sleeves 138 and 142 open at the inner and outer side edges of the baling rails 136 and 140. Other configurations of supports 146 and 148, sleeves 138 and 142, and so on, may also be possible.
[0081] In certain embodiments, a device for wrapping other than a sleeve and sleeve support may be provided. In certain embodiments, for example, a ring or other device can be used to wrap wrapping material (for example, from rolls of wrapping material) around a bale in a baling trough. As shown in FIG. 8, for example, rollers 152 of wrapping material and associated wrapping devices (or other similar arrangement) can be provided as an alternative (or in addition) to holders 146 and 148 and sleeves 138 and 142. Rollers 152 of material wrapping can be supported on (or around) baling chutes 136 and 140 in various ways, and various associated devices (not shown) can link material from rollers 152 around the bales in baling chutes 136 and 140 of way to wrap the burdens.
[0082] In certain embodiments, string or similar material can be used as an alternative (or in addition) to sleeves 138 and 142 (or other wrapping material configurations). As shown in FIG. 7, for example, a number of knots 150 (or other wrapping devices) can be provided for each of the baling chutes 136 and 140. The cord (not shown) can be looped around bales in the baling chutes 136 and 140 and then tied with knots 150 to secure the string to the bales.
[0083] Returning specifically to baler 100, as shown, the various mechanisms noted above can cooperatively cooperate to form a bale in the baling chamber 110, eject the bale into one of the baling chutes 136 and 140, wrap the bale, then eject the bale from the baler 100. Referring again to FIG. 7, for example, the side wall 120 is oriented on the right side of the baling chamber 110 at the beginning of a baling cycle. The cylinder 128 is in an extended configuration, such that the rear wall 126 is located near the front of the baling chamber 110. As a number of initial flakes 114a are successively provided by the feeding mechanism, the reciprocating movement of the plunger 108 compresses the flakes 114a against the rear wall 126 to begin to form a bale. In certain cases, bales already formed 144a and 144b can already rest on the baling rails 136 and 140 inside (or at least partially inside) sleeves 138 and 142.
[0084] Similar to baler cylinder 74 (see, for example, FIG. 2), cylinder 128 and rear wall 126 can be controlled in a variety of ways to facilitate compression of flakes 114a by plunger 108. In certain In implementations, for example, controller 112 can control rear wall 126 based on a predetermined compression distance, a predetermined target pressure, a combination of compression distance and target pressure, or various other parameters.
[0085] Referring again to FIG. 8, as the baler 100 progresses along the field, the baling chamber 110 is gradually filled with a number of compressed flakes 114. As can be seen in FIG. 8, for example, the original flakes 114a (see FIG. 7) are approaching the rear of the baling chamber 110 even when new flakes 114b continue to be distributed for compression. When the baling operation progresses (i.e., from FIG. 7 to FIG. 8), the rear wall 126 is moved further and further back to the rear of the baling chamber 110 by the rear cylinder 128. As noted above, various types control units are possible for cylinder 128 and rear wall 126.
[0086] Referring further to FIG. 9, the various flakes 114 were compressed into the baling chamber 110 into a complete developed bale 144c. The cylinder 122 then causes the side wall 120 to push the bale 144c from the baling chamber 110 to the baling chute 140 for wrapping. As shown, for example, when the bale 144c is pushed from the baling chamber 110, the bale 144c passes to the sleeve 142 of wrapping material supported by the sleeve holders 148. The wrapping material in this way can be wrapped in the bale when the bale passes through (or outside) the sleeve. (It will be understood that, in certain implementations, the bale 144c may be partially enveloped by other wrapping devices (not shown) before, or in the meantime, being ejected from the baling chamber 110 into the chute 140.)
[0087] Where the previously formed bale 144b is already in the baling chute 140, as in the embodiment shown in FIG. 9, the thrust of the new bale 144c from the baling chamber 110 into the baling chute 136 causes the older bale 144a to be moved laterally from the baling chute 136. In certain embodiments, this may additionally contribute to the involvement of the older burden 144b. As shown in FIGS. 7 and 8, for example, when bale 144b is fully supported by baling chute 136, the outer side edges of bale 144b may engage with outer side edge 142a of sleeve 142. This bale engagement 144b with edge 142a (or other portion) of the sleeve 142 causes the bale 144b to pull material from the sleeve 142 when the bale 144b is pushed laterally out of the baler 100. In this way, the wrapping material of the sleeve 142 can envelop the entire side width of the bale 144b when bale 144b is ejected from the baling chute 140 and the baler 100.
[0088] As shown in FIG. 10, when the bale 144b falls from the baling trough 140, a portion 142b of the wrapping material of the sleeve 142 can pull from the sleeve 142 to maintain the wrapped state of the bale 144b. For example, a perforated seam can arrange the sleeve 142 to separate at the edge 142c when the bale 144b falls from the baling trough 140, and in this way allows the portion 142b to remain enveloped in the bale 86a. The edge 142c can then be arranged to engage with the outer side edge of the subsequent bale 144c. Bale 144a can similarly interact with the edge 138a of sleeve 138 when bale 144a is ejected from the baling chute 136.
[0089] Still with reference to FIG. 10, due to the movement of the side wall 120, the bale 144c was ejected from the baling chamber 110 to the baling chute 140 (and to the sleeve 142) and the previously formed bale 144b was ejected, in a completely enveloped state, from the baling chute 140 to the field. With the side wall 120 remaining on the left side of the baling chamber 110, the rear wall 126 can then be returned to the configuration of FIG. 7, in order to allow new incoming flakes 114c to be compressed into the baling chamber 110 in another bale. When this bale (not shown) is completed, the side wall 120 can then be moved by cylinder 122 back to the right side of the baling chamber 110, in order to eject the new bale into the baling chute 136.
[0090] Referring further to FIG. 11, another example baler 160 is shown. (For the clarity of presentation of various internal mechanisms, the baler housing 160 is not shown in the various figures.) Baler 160 can be similar to baler 100 in several ways. For example, baler 160 is generally supported for travel across a field by wheels 162 mounted to a chassis 164. A collection set 166 for collecting cultivation material from a field is provided, which may be similar to collection set 106 Cultivation material collected by the collection set 166 is routed up and back through the baler 160 and formed into generally rectangular flakes 174. The flakes 174 are then compressed into a baling chamber 170 by an reciprocating piston 168 (or other cultivation movement device) to form a burden. Baler 160 may also include one or more controllers 172 configured to control various operations of baler 160.
[0091] In the embodiment shown in FIG. 11, the reciprocating piston 168 moves in a cyclic front-to-back path (i.e., generally left to right, in FIG. 11) as driven by a rotating eccentric arm 176. A feeder assembly successively distributes the flakes 174 of cultivation material (for example, flakes 174a shown in FIG. 2) to the plunger path 168, close to the forward portion of the baling chamber 170. The cyclic movement of the plunger 168 pushes these flakes 174 backward into the baling chamber 170, compressing the flakes 174 for a growing burden. In the embodiment shown in FIGS. 11 to 16, a hydraulic cylinder 178 can be used to move the eccentric arm 176. It will be understood that other arrangements can be used to move the eccentric arm 176, including a gear box similar to the gear box 58 of FIGS. 6A and 6B, an auger, or other mechanism.
[0092] As shown, the baling chamber 170 is generally connected laterally by a single movable side wall 180. The hydraulic cylinder 182 (or another actuator), mounted on the support structure 184 is configured to act on the side wall 180, which it can be useful to eject the bales formed from the baling chamber 170. For example, as controlled by controller 172, and in coordinated synchronism with plunger 168 and other baler components, cylinder 182 can move sidewall 180 sideways through baling chamber from left to right and from right to left. In this way, the plunger 168 and side wall 180 can alternately eject bales formed into the right and left sides of the baling chamber 170.
[0093] It will be understood that other configurations may be possible. In general, to eject bales formed from chamber 170, a side member of various designs can be moved laterally (or otherwise) by the baling chamber 170. In certain embodiments, the side member can be configured as a complete side wall of the baling chamber 170, as with the side wall 180. In certain embodiments, the side member can be configured in another way. For example, a mesh, mesh, grid, or other partial wall can be provided, which can also be moved laterally by the baling chamber by an actuator of various types. Similarly, a piston, plunger, or other side member can be provided, which may not sweep the entire length, height, or width of chamber 170, but which can be acted on independently to eject a bale from chamber 170. In certain embodiments, a side member can be oriented on a side of the baling chamber 170 different than a side side of the baling chamber (e.g., a top, bottom or rear side of the chamber 170). In certain embodiments, various connections, rotating members or other actuating mechanisms can be used in place of cylinder 182 and support structure 184.
[0094] In the embodiment shown in FIG. 11, no portal similar to portal 60 (see, for example, FIG. 5) is used to control (for example, open and closed) an ejection passage for the release of a bale from the baling chamber 170. In certain modalities, however, a portal of various configurations can be used, including a portal similar to portal 60 of FIGS. 2 to 5.
[0095] Still referring to FIG. 11, a rear wall 186 of the baling chamber 170 provides resistance to the plunger 168 so that several flakes 174 are compressed by the plunger 168 into a finished bale. An actuator, such hydraulic cylinder 188 is provided (for example, supported with respect to chassis 164 by a support structure 190), in order to control the performance of the rear wall 186. As discussed above, with respect to cylinder 74 and the rear wall 72, and cylinder 128 and rear wall 126, cylinder 188 (or another actuator) can control rear wall 186 based on predetermined compression distances, compression pressures, or various other factors.
[0096] As shown, as the rear wall 186 connects with the baling chamber 170 opposite the plunger 168 (or other cultivation movement device), the baling chamber 170 can be viewed as a blind baling chamber. Other types and configurations of a rear wall of the chamber 170 can be provided as an alternative to the rear wall shown 186. In certain embodiments, for example, the baling chamber 170 may not include a rear wall and therefore cannot be a blind chamber.
[0097] The various support structures 184 and 190 for cylinders 182 and 188 (or other support structures for other actuators) can be configured in a variety of modes. As shown, support structures 184 and 190 include welded metal tubing with the frame 164 of the baler 160 in order to rigidly support the cylinders 182, and 188 with respect to the frame 164 and the baling chamber 170. Other arrangements also are possible.
[0098] A plurality of baling chutes can also be provided in the baler 160, for receiving and wrapping bales that are ejected from the baling chamber 170. In the embodiment shown in FIG. 11, for example, a baling chute 196 is configured as a platform that is laterally adjacent to, and extends laterally away from, the right side of the baling chamber 170. Appropriately, a bale ejected from the right side of the baling chamber. baling 170 can generally pass to baling chute 196 before being ejected from baler 160 into the field (or other location). Similarly, a baling chute 200 is configured as a platform that is laterally adjacent to, and extends laterally away from, the left side of the baling chamber 170. Appropriately, a bale ejected from the left side of the baling chamber 170 in In general, it can pass to baling chute 196 before being ejected from baler 160 into the field (or other location).
[0099] As shown, baling troughs 196 and 200 are generally oriented horizontally, such that a bale resting on any of the baling troughs 196 and 200 may tend to remain in baling troughs 196 and 200, absent active ejection force (or bale inclination 160). Other configurations are also possible, including configurations in which any of the baling chutes 196 and 200 can be oriented obliquely with respect to the horizontal. In certain embodiments, one or more of the baling troughs 196 and 200 itself can be movable. For example, a hydraulic actuator (not shown) can be provided to tilt one of the baling chutes 196 and 200 away from the baling chamber 170 in order to encourage a burden on the baling chute 196 or 200 to slide from the chute 196 or 200.
[00100] As noted above, a baling chute in general can support, or be otherwise associated with, a wrapping device. Thus, if a bale is in an uninvolved (or partially uninvolved) state when ejected from a baling chamber into a baling trough, the bale can be wrapped in the baling trough before being ejected into the field ( or elsewhere). As shown in FIG. 11, baler 160 includes several wrap frames 206 and 208 supported by baling rails 196 and 200, respectively (or otherwise supported by chassis 164). As shown, the wrap frames 206 and 208 are configured as metal boxes (or others) with continuous sheets of metal forming the top, front and back sides of the wrap frames 206 and 208, and with the upper surfaces of the baling 196 and 200, respectively, forming bottom sides of wrap frames 206 and 208. The laterally inner and outer sides of wraps 206 and 208 are open, such that wraps 206 and 208 generally define a rectangular tube, and bales a from the baling chamber 170 it can pass laterally through the wraps 206 and 208 when the bales move through the baling rails 196 and 200. In other embodiments, the wrap frames 206 and 208 can be configured in another way (for example, as a construction of bundles or piping, such as plastic or other material, such as boxes with meshed sides or otherwise partially open sides, and so on). At the stage of a baling operation shown in FIG. 11, each of the baling troughs 196 and 200 bears a bale (i.e., bales 204a and 204b, respectively) within the associated wrap frame 206 or 210. In another stage, other bales numbers can be supported.
[00101] In general, the wrap frames 206 and 208 can be configured to support separate sleeves of wrapping material. In this way, for example, as a bale being ejected from the baling chamber 170 passes through the respective wraps 206 and 208, the bale can be enveloped by the sleeves of wrapping material. In certain embodiments, as described in more detail below, a sleeve of wrapping material supported by any of the wrap frames 206 and 208 may not be engaged to wrap a bale until the bale is moved through the wrap frame 206 or 208 , respectively (for example, when the bale is being ejected from the baling chute 196 or 200 into the ground). In certain embodiments, as described in more detail below, wraps 206 and 208 can be configured such that a sleeve of wrapping material can be formed in wraps 206 and 208 from blades of wrapping material during the operation of baler 160 .
[00102] In the embodiment shown in FIGS. 11 to 16, a roll 210 of a sheet of wrapping material * kuVo fi, “fonjc fg kpx„ nwetq ”+ 432c fi supported by baler 160 with respect to wrapper frame 206 and a roll 212 of wrapper sheet 212a is supported by the baler 160 with respect to the wrap frame 208. The sheet back 210a and 212a of the rollers 210 and 212 can take a variety of shapes, including, for example, plastic sheet, wrapping net, breathable wrap sheet, composite sheets , and so on. During the operation of the baler 160, as described in more detail below, the rollers 210 and 212 can be moved in a generally cyclic path around the respective wrap frames 206 and 208 such that the sheet back 210a and 212a on the rollers 210 and 212 is formed into sleeves around the wrap frames 206 and 208. Bales that pass through the sleeves can then engage the leaf loop 210a or 212a such that the bales are properly wrapped before being ejected into the field (or elsewhere) place).
[00103] The sheet turn 210a and 212a in rolls 210 and 212 can be wrapped in the sleeves in several ways. As shown, baler 160 includes track 214 and 216 generally extending around wrap frames 206 and 208. Correspondingly, support structures for rollers 210 and 212 include members (e.g., wheels) for engaging the tracks 214 and 216, respectively. As the members of the support structures move along the tracks 214 and 216, and the rollers 210 and 212 can be moved appropriately in successive cycles around the circuits prescribed by the tracks 214 and 216, and sleeves of wrapping material created . As shown, for example, roll 212 is supported by a frame including a wheel 218 that engages track 216 so as to carry roll 212 in a cyclic path around wrap frame 208. However, it will be understood that other configurations may be possible. Various actuators (not shown) or other mechanisms (for example, electric motors, gear or chain and sprocket arrangements, and so on) can be provided to move rollers 210 and 212 along the path around rails 214 and 216.
[00104] Still with reference to the example baler 160, the various mechanisms noted above can cooperate cooperatively to form a bale in the baling chamber 170, eject the bale into one of the baling chutes 196 and 200, wrap the bale, then eject the bale from the baler 160. As shown in FIG. 11, for example, the side wall 180 is oriented on the right side of the baling chamber 170 at the beginning of a baling cycle. The cylinder 188 is in an extended configuration, such that the rear wall 186 is located near the front of the baling chamber 170. As a number of initial flakes 174a are successively provided by the feeding mechanism, the reciprocating movement of the piston 168 compresses the flakes 174a against the rear wall 186 to begin to form a bale. In certain cases, including as shown, bales already formed 204a and 204b can now rest on baling rails 196 and 200 within (or at least partially within) sleeves 198 and 202.
[00105] Referring further to FIG. 12, when the baler 160 progresses along the field, the baling chamber 170 is gradually filled with a number of compressed flakes 174. As can be seen in FIG. 12, for example, the original flakes 174a (see FIG. 11) are approaching the rear of the baling chamber 170 yet as new flakes 174b continue to be distributed for compression. When the baling operation progresses (i.e., from FIG. 11 to FIG. 12), the rear wall 186 is moved farther and farther to the rear of the baling chamber 170 by the rear cylinder 188. As noted above, various types of control are possible for cylinder 188 and rear wall 186.
[00106] When the new bale is being formed in the baling chamber 170 from the various flakes 174, a wrapping process for one or both of the bales 204a and 204b can be performed. (It will be understood that the engagement process can also be performed at other times.) As shown in FIG. 12, for example, as the flakes 174 are being compressed inside the baling chamber 170, the roll 212 of the wrapper sheet is moved along the rail 216 (for example, by means of the wheel 218 (see FIG. 11)) such that the roll 212 begins to form the sheet loop 212a in a sleeve surrounding the wrap frame 208. As shown, a cutting mechanism 220 secures one end of the sheet loop 212a, such that the sheet loop 212a can be developed from roll 212 when roll 212 moves around wrap frame 208. However, it will be understood that other component devices can be used to fix (or otherwise anchor) the sheet web 212a, or otherwise ensure that sheet web 212a properly unwinds from roll 212. Still as shown, a portion 222 of sheet web 212a, which will eventually form a sleeve portion of wrapping material, extends laterally outward from the outer edges of the web frame wrap 2 08. As described in greater detail below, this portion 222 of leaf loop 212a may allow bale 204b to engage with leaf loop 212a such that bale 204b is appropriately wrapped when ejected from baling chute 200.
[00107] In the stage in the wrapping (and baling) operation represented in FIG. 12, the roll 212 has not yet completed a complete cycle (e.g., a complete revolution) around the wrap frame 208. Thus, a complete cycle of the sheet revolution 212a has not yet been formed. When the wrapping (and baling) operation continues, the roll 212 may continue along the cyclic path defined by the rail 216, such as a complete cycle, and thus a sleeve (or at least a portion of it) of the leaf loop 212a is completed.
[00108] As shown, roll 210 is held in a stationary position with respect to rail 214 when roll 212 is moved around rail 216 to create a foil loop sleeve 212a around wrap frame 208 In other implementations, rollers 210 and 212 can be moved simultaneously around respective rails 214 and 216 so as to simultaneously, at least in part, form sleeves of wrapping material 210a and 212a around respective wrap frames 206 and 208.
[00109] Referring further to FIG. 13, when the roll 212 completes a number of cycles around the rail 216 and the wrap frame 208, a sleeve 224 can be formed from one or more meshes of the foil loop 212a. As noted above, portion 222 of wrapping material 212a (and thus portion 222 of sleeve 224) may extend laterally outwardly beyond the outer edges of wrap frame 208. This can be useful, for example, in in order to ensure that bale 204b appropriately engages sleeve 224 to wrap bale 204b. In the embodiment shown, the sleeve 224 is formed of at least two meshes of the web loop 212a. In other embodiments, the sleeve 224 can instead be formed from a different number of meshes of the web loop 212a.
[00110] In order to cut the foil loop 212a forming the sleeve 224 from the foil loop 212a remaining on the roll 212, the cutting mechanism 220 can move a cutting tool through the foil loop 212a at a location of cut 232. Cutter 220 can be configured in a variety of ways, including with a cutter blade 226 moved by an electric or hydraulic actuator, such as an electric cable (not shown) powered by an electrical power source (for example , to cut sheet of plastic wrap by applying chain to melt the wrapping of the sheet), and so on. As shown, the cutting blade 226 can be configured as a generally straight blade, and the cutting mechanism 220 can include a linear actuator to move the cutting blade 226 laterally, with respect to the baler 160, in order to cut the turn sheet 212a (see FIG. 13) and to store cutting blade 226 at the rear of baler 160 between cutting operations (see FIG. 14). Another cutting mechanism 228 (for example, similar) can be provided to cut the leaf loop 210a in the baling trough 196, or a single cutting mechanism can be used to cut the leaf loop 212a and the leaf loop 210a. Once the leaf loop 212a has been cut, the cutting mechanism 220 can fix (or otherwise anchor) the free end of the leaf loop 212a in order to facilitate further development of the leaf loop 212a from the roll 212 to the formation of a subsequent sleeve (not shown).
[00111] In certain implementations, it may be useful to cut the sheet loop 212a (and the sheet loop 210a) by directing the cutting force to the sheet loop 212a away from the formed sleeve 224 (or sheet loop 210a) ). In this way, for example, if excessive cutting force is inadvertently applied, or if the cutting blade 226 or other mechanism is inadvertently moved too far through the sheet back 212a, damage to the sleeve 224 itself can be avoided. In the embodiment shown, the cutting mechanism is arranged at the rear end of the baler 160. Therefore, it may be useful to apply the cutting force to the leaf loop 212a in a generally backward direction, in order to avoid damage to the sleeve 224. In certain embodiments, the cutting mechanism can be configured (or controlled, such as by controller 172) such that the cutting blade 226 is extended to cut the web back 212a relatively promptly after the roll 212 has passed the cutting blade 226 In this way, the cutting blade 226 can be extended in a gap 230 between the leaf blade 212a and the sleeve 224 and the leaf blade 212a can be cut by the cutting blade 226 with a cutting force that is generally directed away from sleeve 224 (that is, in a backward direction, as shown). As shown, the gap 230 can of course result from the geometry of the development of the leaf loop 212a from the roll 212, such that the cutting blade 226 can be moved in the gap 230 based on the synchronization of the movement of the roll 212 around the rail 216 and beyond the cutting mechanism 220. However, it will be understood that other configurations and implementations may be possible.
[00112] As shown in FIG. 13, the cutting operation for the leaf loop 212a can be performed when a new bale is newly formed within the baling chamber 170, but new flakes 174c of cultivation material are still being fed into the baling chamber 170 for compression . This can be useful, for example, in order to ensure that sleeve 224 is properly prepared to wrap bale 204b before bale 204b is ejected from baling chute 200 (i.e., to make room for a new bale from baling chamber 170). In other implementations, another synchronization can be used to cut the leaf loop 212a (as well as to wrap the leaf loop 212a to create the sleeve 224). For example, the leaf loop 212a can be cut once a new bale has been completely formed in the baling chamber 170, when a new bale is not as close to the end as shown in FIG. 13, or with several other synchronizations.
[00113] Referring further to FIGS. 14 to 16, the various flakes 174 were compressed into the baling chamber 170 into a complete developed bale 204c. Cylinder 182 can then cause side wall 180 to push bale 204c from baling chamber 170 to baling chute 200. In certain embodiments, this movement of bale 204c can also cause a previously formed bale to be ejected baling chute 200. As shown, for example, when bale 204c is pushed from baling chamber 170, bale 204c passes into wrap frame 208, thereby pushing bale 204b out of wrap frame 208 and outside the baling chute 200.
[00114] As is also noted above, when a bale moves out of a baling chute, the bale can pull a sleeve of material from wrapping with the bale, such that the bale can be completely wrapped before falling to the ground ( or elsewhere). Referring specifically to FIG. 15, for example, when the bale 204b is pushed laterally from the wrap frame 208, the laterally outer edge 234 of the bale 204b engages the exposed portion 222 of the leaf loop 212a such that when the bale 204b moves out of the wrap frame 208 (see FIG. 15) and then falls off the baling chute 200 (see FIG. 16), bale 204b pulls sleeve 224 of wrap frame 208 to wrap bale 204b.
[00115] With reference in particular to FIG. 16, due to the movement of the side wall 180, bale 204c was ejected from the baling chamber 170 to the baling chute 200 (and to the wrap frame 208) and the previously formed bale 204b was ejected, in a completely enveloped state, from the baling chute 200 to the field. With the side wall 180 remaining on the left side of the baling chamber 170, the rear wall 186 can then be returned to the configuration of FIG. 11, in order to allow new flakes arriving 174d to be compressed inside the baling chamber 170 in another bale. When this bale (not shown) is completed, the side wall 180 can then be moved by cylinder 182 back to the right side of the baling chamber 170, in order to eject the new bale into the baling trough 196.
[00116] In certain embodiments, bales can somehow be compressed in excess within a baling chamber, with respect to the expected dimensions of the bales once they have been wrapped and ejected from the baler. In such modalities, baling chutes and wrap frames (or other aspects of a baler) can sometimes be configured to be somehow smaller than the final dimensions of the ejected bales, in order to maintain some degree of excess compression when the bales are supported by (and contained within) baling chutes and wrap frames (or elsewhere in the baler). In this way, for example, when the bales are ejected from the baling chutes, the bales can expand into the sleeves of wrapping material supported by the wrap frames, thus ensuring a relatively tight turn of the bales by the wrapping material. For example, in the embodiment shown in FIGS. 11 to 16, bale 204b may have been compressed to some extent in excess within the baling chamber 170, and the baling chute 200 and wrap frame 208 may be configured with dimensions that maintain some degree of excess compression when the bale 204b is supported by the baling chute 200. When the bale 204b is ejected from the baling chute 200 and the wrap frame 208 (for example, as shown in FIG. 15), the bale 204b can expand from its excess compressed state for sleeve 224 such that sleeve 224 retains bale 204b with increased pressure and tightness.
[00117] In certain embodiments, other configurations of the 206 and 208 wrap frames (or other wrap frames) may be possible. For example, as shown, the wrap frames 206 and 208 are formed as relatively rigid wraps with generally square sides and corners. In certain embodiments, a wrap frame can be configured to generally tilt inward (i.e., to a bale within the deformation wrap), such that the laterally outer edges of the wrap frame form an outlet opening that somehow it is smaller than an entry opening formed by the laterally inner edges of the wrap frame. This can be useful, for example, in order to make it easier to easily pull a wrapper sheet sleeve from the wrap frame when a bale moves from the wrap frame of the relevant baling trough. In certain embodiments, a wrap frame can be configured as a telescopic, collapsible, expandable, or otherwise deformable or mobile structure. This can be useful in a variety of cases.
[00118] Various baling and wrapping features, including several operations described above, can be performed as part of a method for wrapping and wrapping * “BY” +. swg rqfg ugt eqpVtqncfq. at least in part, by a controller of various configurations (for example, one of controllers 32, 112, or 172). Referring further to FIG. 17, for example, a controller can assist in performing various operations of a BW 300 method.
[00119] The BW 300 method may include operating a plunger 302 to compress cultivation material within a baling chamber. As described above, for example, plungers 48 and 108 can be operated, respectively, to compress flakes 54 and 114 of cultivation material within baling chambers 50 and 110. In certain embodiments, an eccentric arm (for example, one of the eccentric arms 56 and 116) attached with any of the plungers 48 and 108 can be driven to rotate such that the plungers 48 and 108 perform an alternating movement with respect to the baling chambers 50 and 110. This movement can compress successively distributed flakes 54 and 114 in a bale within the respective baling chamber 50 or 110.
[00120] In certain embodiments, the relevant baling chamber can be a blind baling chamber with a rear wall, and the reciprocating movement of the plunger can compress 304 growing material against this rear wall. Referring further to FIG. 18, in such a case, the rear wall can be controlled in several ways. In certain implementations of method 300, one or more actuators (for example, hydraulic cylinders such as cylinders 74 and 128) may be provided to control the rear wall 306 based on a target pressure. For example, a target compression pressure for the forming bale can be determined, and the appropriate actuator controlled (for example, using, at least in part, an accumulator such as accumulator 78) to provide the target pressure on the rear wall ( for example, moving the rear wall to an appropriate orientation). In this way, cultivation material can be compressed between the plunger and the rear wall with the appropriate pressure.
[00121] In certain implementations, an actuator can be provided to control the rear wall 308 based on a compression distance. For example, a target thickness of a particular flake after compression by the plunger can be determined, and the rear wall moved by the actuator in order to accommodate this compression.
[00122] In certain implementations, the rear wall of a baling chamber can be controlled 310 based on both a target pressure and a compression distance. For example, for each reciprocating piston cycle, an actuator can be controlled to first move the rear wall 312 based on a predetermined compression distance. The piston eccentric arm can then be rotated 314 (or the piston otherwise advanced in its cycle) and, after an appropriate interval (for example, after the eccentric arm has reached an appropriate angle to the horizontal), an appropriate pressure 316 can be provided on the rear wall. Thus, for example, the plunger can initially compress flakes of cultivation material over the compression distance with relatively little resistance from the rear wall. When the rotation of the eccentric arm advances to provide increasing mechanical advantage (that is, when the eccentric arm approaches alignment with the front to back path of the plunger), the rear wall can then be used to resist the plunger with target pressure . This can result in efficient and effective compression of the flakes in relatively highly compressed bales.
[00123] Referring again to FIG. 17, once a bale has been formed (for example, by operating plunger 302), the bale can be ejected 320 from the baling chamber to an adjacent baling chute. In certain implementations, the bale can be ejected in an uninvolved state 322. In certain implementations, the bale can be ejected in a partially uninvolved state 324, such that some amount of wrapping material has been applied to the bale (for example, within baling chamber), but additional wrapping is required before the bale is finally ejected from the baler. In certain implementations, multiple baling rails 326 can be provided, with bales being alternately ejected 320 from the baling chamber to one of multiple rails 326.
[00124] A bale can be ejected 320 from the baling chamber in a variety of ways. In certain implementations, a side member (e.g., a side wall) of the baling chamber can be moved 328 to propel a bale from the baling chamber to the appropriate baling chute. As described above, for example, a hydraulic cylinder can be used to actuate a movable side wall of a baling chamber in order to push (or pull) a bale from the baling chamber into the particular baling chute. In certain implementations, a portal can be provided for the baling chamber, which portal can be moved 330 in order to open an ejection passage for the ejection of the bale from the baling chamber.
[00125] Once injected (as a whole or in part) into a baling chute, a bale can be wrapped 340 with wrapping material. As also described above, a bale can be wrapped 340 in a variety of ways, with a variety of wrapping devices, and with a variety of wrapping material. In certain implementations, a bale can be passed 342 through a sleeve of wrapping material supported on (or close to) the relevant baling chute, such that the wrapping material adheres to the bale and thus appropriately rolls up the bale. In certain implementations, rope loops can be wrapped around a bale and tied 344 by various wrapping (and knotting) devices. In certain implementations, sheets of wrapping material, such as wrapping net or plastic sheet, can be wrapped around a bale.
[00126] In certain implementations, sheets of wrapping material can be wrapped around a wrap frame 348 in order to form a sleeve, and a bale can be passed 350 through the wrap frame to engage the sleeve and thereby wrap the burden. For example, a tunnel or tube-like wrap frame can be supported on a baling chute such that an ejection bale 320 from a baling chamber into the baling chute passes into the wrap frame. Various mechanisms can then (or earlier) be used to wrap 348 sheets of wrapping material around the wrap frame, such that a sleeve of wrapping material is formed around the wrap frame. Once an appropriate sleeve has been formed, the bale can then be moved 350 through the wrap frame such that the bale engages the sleeve and pulls the sleeve from the wrap frame. In this way, the bale can be enveloped by the sleeve of wrapping material formed before the bale is completely ejected from the baler.
[00127] In certain implementations, wrapper foil can be wrapped 348 for a sleeve by moving 352 a roll of the foil loop in a loop (e.g., a circular, rectangular or other path) around the wrap frame. In addition, a cutting mechanism can be provided with a cutting location that is arranged such that the roller moves beyond the cutting location when the roller moves along the circuit. The cutting mechanism can then be actuated 354 to cut the roll sheet back after the roll has passed the cut location. Referring again to FIG. 13, for example, when the roll 212 moves beyond the cutting location 232, a gap 230 can be provided temporarily between the sheet loop 212a and the formed sleeve 224. The cutting mechanism 220 can be actuated 354 such that the blade cutter 226 moves to gap 230 to cut sheet back 212a from roll 212.
[00128] Once properly wrapped, a bale can be ejected 360 from the baling chute. In certain embodiments, a bale can be actively ejected 360 from a baling chute. For example, a side member of the baling chamber may push (or otherwise propel) a bale from a baling trough directly, or it may indirectly push a first bale from the baling trough by pushing a second bale from the baling chamber to the same baling chute. In certain embodiments, a bale can be ejected passively 360 from a baling chute. For example, a baling chute can be oriented at such an angle (or otherwise configured) then a bale moves from the baling chute under the influence of gravity or with limited (or not) active attachment of the bale by a particular actuator.
[00129] As will be perceived by a person skilled in the art, various aspects of the disclosed subject can be incorporated as a computer-implemented method, a system, or a computer program product. Appropriately, certain implementations can be implemented entirely as hardware, entirely as software (including firmware, resident software, microcode, etc.) or as a combination of aspects of software and hardware.
