    The invention relates to a bale wrapper having a frame, a wrapping table movable relative to the frame, which wrapping table is supported on the frame by at least one rocker arm, a receiving station to which the wrapping table can be moved to receive the bale, a wrapping station to which the wrapping table is to be moved. to move the wrapping table between the receiving station and the wrapping station and a wrapping device for wrapping the protective film around the bale. The invention further relates to a combination machine with a bale wrapper according to the invention.
    Forage crops and hay are often stored in round bales. Baling uses trailed combination machines, which lift the feed mattress in the field into the baling chamber in the machine by means of a pick-up roller and form a cylindrical bale as the baler moves. From the baling chamber, the round bale is transferred to a bale wrapping device, where it is tightly wrapped around the bale - an air- and water-tight plastic protective film. The bale wrapper can also be a separate device for wrapping bales made with a separate baler in a protective film. In known combination machines, a bale wrapper is located at the rear of the device and a baling chamber at the front of the device. The round bale is transferred from the baling chamber along a conveyor to a separate wrapping table belonging to the bale wrapping device. The wrapping table typically comprises two parallel support rollers on which a bale in a horizontal position is rotated about its longitudinal axis. At the same time as the bale is rotated, an extensible protective film is wrapped around the bale by means of a wrapping device. After wrapping the protective film, the wrapping table is tilted so that the bale wrapped in the protective film rolls from the wrapping table to the field, 00 25 - where it is left to wait for transport to the warehouse or place of use.
    EP 0865723 B1 and EP 1438889 B1 describe combination machines 3 with a movable wrapping table that can move between the receiving>> position of the baling chamber and the wrapping station of the bale wrapping device along guides. A typical problem with mobile = wrapping tables is their slow speed of movement, which causes o 30 delays in the operation of the device. In EP 0865723 B1 the wrapping table is conveyed by a 3 chain drive mechanism and in EP 1438889 B1 by several separate hydraulic cylinders. Conductors and chain-driven mechanisms are prone to malfunctions N, especially in wet and damp operating environments. Em. transmission mechanisms are also structurally complex and have high manufacturing costs.
    DE 20015653 U1 describes a wrapping apparatus for round bales comprising a wrapping table suspended from the frame by means of a frame and L-shaped support arms. The massive frame belonging to the bale wrapping equipment requires such a large space that it is difficult to arrange the equipment in a mobile combination machine, for example. The object of the invention is to provide a bale wrapper and a combination machine which can reduce the disadvantages and drawbacks associated with the prior art. The objects according to the invention are achieved by a bale wrapper and a combination machine, which are characterized by what is stated in the independent claims. Some preferred embodiments of the invention are set out in the dependent claims. The invention relates to a bale wrapper having a frame and a wrapping table movable relative to the frame, which is supported on the frame by at least one rocker arm. The bale wrapper has a receiving station to which the wrapping table can be moved to receive the bale, a wrapping station to which the wrapping table can be moved for wrapping the protective film, an actuator for moving the wrapping table between the receiving station and the wrapping station and a wrapping device for wrapping the protective film. The body comprises at least one support rail having a longitudinal direction and the wrapping table has support members with which the wrapping table is supported on said support rail movably in the longitudinal direction of the support rail. Preferably, the support rail has a substantially longitudinal support surface of the support rail and the first support members comprise support wheels moving along the support surface of the support rail. A preferred embodiment of the bale wrapper according to the invention comprises two parallel rocker arms and the wrapping table is articulated to the first rocker arm and the second rocker arm. In another preferred embodiment of the bale wrapper according to the invention, the rocker arms are L-shaped parts with a first = end attached to the frame and a second end attached to the wrapping table.
    A third preferred embodiment of a bale wrapper according to the invention comprises = two parallel support rails and the wrapping table has a first side edge, = 30 - from which it is supported on the first support rail, and a second side edge from which it is> supported on the second support rail.
    In another preferred embodiment of the bale wrapper according to the invention, the wrapping table has a front edge and a rear edge and the wrapping table is attached to the rocker arms at its front edge.
    In another preferred embodiment of the bale wrapper according to the invention, the first support members are between the front edge and the rear edge, at a distance from the rear edge.
    In another preferred embodiment of the bale wrapper according to the invention, said actuator for moving the wrapping table between the receiving station and the wrapping station is arranged to turn the rocker arms. Preferably, said actuator - is a hydraulic cylinder attached at one end to a frame and at the other end to a rocker arm.
    In another preferred embodiment of the bale wrapper according to the invention, the rocker arms can be brought into a first position, in which the wrapping table is in the receiving position, and in a second position, in which the wrapping table is in the wrapping station.
    In yet another preferred embodiment of the bale wrapper according to the invention, the wrapping table can be brought into a unloading position in which the front edge of the wrapping table is substantially higher in height than the rear edge when the bale wrapper is in the normal operating position.
    In another preferred embodiment of the bale wrapper according to the invention, the shape of the support surface in the longitudinal direction of the support rail is different from the straight line.

In a further preferred embodiment of the bale wrapper according to the invention, the N 25 wrapping table further comprises second support members with which the wrapping table is supported x on said support rails movably in the longitudinal direction of the support rails, the second support members comprising support wheels moving along the support surface. In yet another preferred embodiment of the bale wrapper according to the invention, the wrapping table has an articulated pin at the front edge and an elongate slot at the other end of the rocker arm attached to the wrapping table, in which slot the articulated pin is adapted to move. Due to the attachment between the wrapping table and the rocker arm made by means of an elongate slot and a pivot pin movable in the slot, the curved trajectory of the rocker head does not affect the height of the front edge of the wrapper table, but the wrapper table In yet another preferred embodiment of the bale wrapper according to the invention, the slot has a first end and a second end such that the first end is lower in the height direction than the second end when the rocker arm is in the second position.

Preferably, the notch has a curved shape. The slotted portion of the rocker arm may also have a curved shape like the slit. The combination machine according to the invention comprises a baling chamber for forming a bale and for wrapping a protective film of a bale wrapper around the formed bale. The bale wrapper is one of the bale wrappers described above. The advantage of the bale wrapper according to the invention is that it is structurally simple and reliable. Thanks to the simple structure, savings are made in the production and maintenance costs of the bale wrapper. The invention will now be described in detail with reference to the accompanying drawings, in which Figure 1a shows an exemplary bale wrapper according to the invention - side view, Figure 1b - rear view of the bale wrapper shown in Figure 1a, © Figures 1c, 1d and 1e show the bale wrapper shown in Figures 1a and 1b tuna, NV Fig. 2 shows by way of example a bale wrapper according to the invention. . . - 25 - a preferred embodiment seen from the side,

    N ta described from the side.
    Figures 1a and 1b show by way of example a bale wrapper according to the invention.
    Figure 1a shows the bale wrapper from the side and Figure 1b from the back.
    In the following, both images are described simultaneously.
    The bale wrapper has two parallel, substantially parallel support rails 16a, 16b connected at one end by a connecting beam 31 transverse to the longitudinal direction of the support rails to a drawbar 32. The support rails are U-profiles made of steel, the gutter-like surfaces of which open towards An L-shaped support post 34 is attached to the second edge surface of each support rail so that the first prong of the support post is secured to the support rail in a position substantially perpendicular to the support rail and the second prongs of the support posts are connected at their ends.
    The support rails, the connecting beam connecting them and the support posts form the body of the bale wrapper.
    At the junction of the second prongs of the support posts is a motor 36 to which two L-shaped wrapping arms 56 are rotatably attached, the free ends of which point substantially vertically downwards.
    The wrapping arms have supports to which protective film rolls 58 are attached. In the center of the circular path of movement of the wrapping arms is a wrapping station 14 (Figure 1a) in which the wrapping table 24 is positioned on the wrapping table for wrapping the bale 100 resting on the wrapping table.
    The wrapping table 24 belonging to the bale wrapper is a device known per se, comprising - two parallel support rollers, an endless belt revolving around the support rollers and a motor rotating the second support roll.
    Using the motor, the bale on the wrapping table is made to rotate about its horizontal axis at the same time as the rolls of protective film rotate the bale about the vertical axis of rotation.
    This wraps the protective film evenly on the outer surface of the bale. © 25 - The wrapping table 24 is suspended by two L-shaped rocker arms 26a, 26b on the support N posts 34 so that the rocker arms are attached at its first end by a pivot pin N to the support post and at the second end at the front edge of the wrapping table 18. The rocker levers are located on the outer edges of the wrapping table. the wrapping table remains between the rocker arms.
    At the front edge of the wrapping table there are pin-like ri- = 30 - mounting members 22 to which the other ends of the rocker arms are attached.
    The wrapping table is further supported by two support members in the form of a support wheel 28 on support rails 16a, 16a.
    The support wheels are mounted on a shaft on each side of the wrapping table so that the first support wheel is on the first side of the wrapping table 24 and the second support wheel is on the second side of the wrapping table.
    The support wheels are located - inside the gutter-like parts of the support rails so that they can roll along the inner surface of the support rail flange.
    The surface of the flange of the support rail 16a, 16b forms a support surface 30 along which the wrapping table can move in the longitudinal direction of the support rail.
    The bale wrapper further includes a shaft 39 having a ring 40 at each end. The shaft is attached to the lower surface of the support rails 16a, 16b.
    Thanks to the tires - the bale wrapper can be moved by pulling along the base.
    In Figure 1a, one of the rings has been removed to better show the structure of the bale wrapper.
    The bale wrapper wrapping table 24 shown in Figure 1a is in the first extreme position of its trajectory between the support posts 34 near the drawbar 32. This wrapping table location is referred to herein as receiving station 12. The wrapping table is moved to the receiving station when a new wrapping table is placed on the wrapping table. by turning the rocker arms to the first position shown in Figure 1a, the rocker arms pulling the wrapping table along the support rails to the receiving station.
    To change the position of the rocker arms, the bale wrapper has a double-acting hydraulic cylinder-42, the length change of which causes the rocker arm to rotate around the attachment point of the first end.
    The body of the hydraulic cylinder is attached to the end of the protrusion 35 in the support post 34, and the end of the piston rod is attached to the rocker arm.
    When the turntable is in the receiving position, the hydraulic cylinder is in its shortest position.
    The hydraulic cylinder is preferably connected by hydraulic hoses to the hydraulic system of the bale wrapper.
    Figures 1c and 1d show, by means of a series of figures, the movement of the wrapping table from the receiving station shown in Figure 1a to the wrapping station 14. Figures 1c and 1d show the bale wrapper shown in Figure 1a at different stages of the wrapping table's path.
    In the following, both images will be described simultaneously. When the bale 100 is placed on the wrapping table 24 at the receiving station, the rocker arms 26a are started to rotate clockwise by extending the hydraulic cylinder 3 42, whereby the wrapping table begins to move towards the wrapping station.
    During the movement of the wrapping table, it rests at its front edge on the rocker arms and via the support wheels 28 = support rails 16a.
    As the wrapping table moves, the support wheels roll along the support surface of the support rails.
    The rocker arms 26a are pivoted to the second position 3 of Fig. 1d, where the first jaw of the rocker arms is substantially parallel to the support post 34D and the second jaw of the rocker arm is substantially parallel to the support rail 16a.
    At the same time, the wrapping table 24 moves through the intermediate station shown in Fig. 1c to the wrapping station 14 shown in Fig. 1d. A protective film is wrapped around the bale in the wrapping station by rotating the wrapping rolls supporting the protective film rolls 58.
    stems around 56 bales. At the same time as the wrapping arms are rotating, the bale on the wrapping table is rotated about its central axis by rotating the wrapping table belt on which the bale rests on the motor. Figure 1e is a side view of the bale wrapper shown in Figures 1a-1d. The figure shows a situation in which the protective film is wrapped around the bale 100 and the bale is removed from the wrapping table 24. The bale is removed by tilting the wrapping table 24 to the unloading position according to Fig. 1e. The wrapping table is brought into the unloading position by increasing the length of the hydraulic cylinder 42, whereby the rocker arms 26a rotate so that the ends of their second prongs rise upwards. In this case, the wrapping table rotates about the mounting axis of the support wheels 28 to a unloading position in which the front edge 18 of the wrapping table is substantially higher than the rear edge 20 of the wrapping table. The bale 100 wrapped in the protective film then wraps over the rear edge of the wrapping table. Once the bale has left the wrapping table, the hydraulic cylinder 42 is brought back to the shortest length, at which point the wrapping table moves through the intermediate station to the receiving station. Figure 2 shows an exemplary side view of a preferred embodiment of a bale wrapper according to the invention. This embodiment of the invention comprises all the same structural parts as the bale wrapper described in Figures 1a-1e. The embodiment of Figure 2 differs from the invention described above in the shape and structure of the support rails 16a, 16b. In Figure 2, the width of the web of the support rails varies in the longitudinal direction of the support rail so that the width of the support rail is greatest in the middle region of the length of the rail. Attached to the inner surface of the web of the support rail is a metal strip, the upper surface of which forms a support surface 30 along which the support wheels 28 roll as the wrapping table 24 moves between the receiving station and the wrapping station. The support surface comprises a curved portion having a shape substantially similar to the shape of the trajectory of the second jaw end of the rocker arm 26a, 26b as the rocker arm moves from the first position shown by the dotted line in Fig. V to the second position shown by the solid line. Due to the curved shape of the support surface, the wrapping table 24 remains in a substantially horizontal position during the movement of the wrapping table, which helps to keep the bale on the wrapping table.
    S = Figure 3a shows by way of example another preferred embodiment of a wrapper according to the invention. This embodiment of the invention comprises all the same structural parts as the baler described in Figures 1a-1e. The embodiment shown in Figure 3a has two parallel support rails 16a, 16b with a substantially straight support surface. Figure 3a shows only the first support rail 16a with the second support rail 16b remaining invisible behind it.
    In addition to the first support members 28, the wrapping table has second support members 29 on which the wrapping table can move along the support rails 16a, 16b.
    The second support members are similar to the first support members, i.e. they comprise support wheels moving along the support surface of the support rails.
    The second support members are located in the longitudinal direction of the wrapping table as viewed closer to the front edge 18 of the wrapping table than the first support members.
    The wrapping table is thus supported by one first support member 28 and one second support member 29 on the first support rail 16a and one first support member 28 and one second support member 29 on the second support rail 16b.
    Alternatively, the wrapping table may be supported on one support rail by one first support member and one second support member and on the second support rail by only one support member located substantially in the longitudinal direction of the wrapping table substantially in the center of the wrapping table.
    The advantage of such a support for a wrapping table with three support members is that the possible shape defects of the wrapping table and the support rails have less effect on the movement of the wrapping table along its trajectory.
    The embodiment shown in Figure 3a also differs from the invention described above in terms of the shape and construction of the rocker arms 26a, 26b and the fastening between the wrapping table 24 and the rocker arms.
    The other ends of the rocker arms 26a, 26b attached to the wrapping table have a curved elongate groove 33. The slot has a first end closer to the end of the rocker arm and a second end closer to the corner of the rocker arm.
    On each side edge of the wrapping table, very close to the front edge of the wrapping table, there is a pivot pin 25, the free end of which - extends through the slot.
    In Figure 3a, the rocker arms are in their first position, with the wrapping table in the receiving station 12. There may be two rocker levers, one on each side of the wrapping table, or only one attached to only one N support post 34. J Figures 3b and 3c show a series of wrapping tables. 24 transition from the receiving station 12 shown in Fig. 3a to the wrapping station 14. Figs. 3b and 3c o show the bale wrapper shown in Fig. 3a at different stages S of the trajectory of the wrapping table.
    In the following, both images are described simultaneously. When the bale 100 is placed on the wrapping table 24 at the receiving station, the rocker arms 26a, 26b are started to rotate clockwise by extending the hydraulic cylinder 42, whereupon the wrapping table begins to move towards the wrapper station by pushing the rocker arms.
    During the movement of the wrapping table, it rests on the first support members.
    via the supports 28 and the second support members 29 to the support rails 16a, 16b. As the wrapping table moves, the support wheels of the support members roll along the rectilinear support surface of the support rails 16a. During the rotation of the rocker arms, the pivot pins attached to the front edge of the wrapping table move in the slot 30 in the longitudinal direction of the slot. The rocker arms 26a are pivoted to the second position of Figure 3c, where the first crotch of the rocker arms is substantially parallel to the support post 34 and the second crank of the rocker arm is substantially parallel to the support rail 16a. At the same time, the wrapping table 24 moves through the intermediate station shown in Fig. 3b to the wrapping station shown in Fig. 3c. A protective film is wrapped around the bale in the wrapping station by rotating the wrapping arms 56 supporting the protective film rolls 58 around the bale. At the same time, during the rotation of the wrapping arms, the bale on the wrapping table is rotated about its central axis by motor-rotating the belt of the wrapping table on which the bale rests.
    Figure 3d shows a situation in which the protective film is wrapped around the bale 100 and the bale is removed from the wrapping table 24. The bale is removed by tilting the wrapping table 24 to the unloading position according to Figure 3d. The wrapping table is brought into the unloading position by increasing the length of the hydraulic cylinder 42, whereby the rocker arms 26a rotate so that the ends of their second prongs rise upwards. In this case, the wrapping table rotates around the fastening shaft of the first support members 28 to a unloading position in which the front edge 18 of the wrapping table is substantially higher than the rear edge 20 of the wrapping table 20. The upper edge of the support rails is designed to allow the upper support wheels of the second support members 29 to rise. The bale 100 wrapped in the protective film then wraps over the rear edge of the wrapping table away from the wrapping table. When the bale has left the wrapping table, the hydraulic cylinder 42 is brought back to the shortest length, at which point the wrapping table moves through the intermediate station to the receiving station. Fig. 4 shows an exemplary side view of a combination NV machine according to the invention. The combination machine is equipped with a J bale wrapper according to the invention. The combination machine has an elongate frame 10 consisting of beam-like parts, to which are mounted two shafts with rings 40 at the ends. O At the first end of the frame there is a drawbar 32 with a drawbar eye for attachment to the implement or towing vehicle. In addition, the first end 2 of the frame has a baling chamber 60, the edge of which, on the drawbar side, has means N for collecting the material to be baled from the field and leading it inside the baling chamber. Inside the baling chamber, there are baling means by means of which the baler forms a bale material fed into the baling chamber, such as fodder plants or
    of this, a round bale. The baling chamber comprises a front part fixedly attached to the frame 10 and an openable rear wall 62 hinged at its upper edge to the upper edge of the front part. The rear wall can be turned to the opening position shown by the broken line in the figure, whereby the bale 100 formed in the baling chamber can be rolled outside the baling chamber to the bale receiving station. The baling means included in the baling chamber are a technique known per se and will not be described in more detail in this connection.
    The bale wrapper according to the invention can be built on the body of the combination machine after the baling chamber or alternatively the baling chamber can be arranged on the body of the bale wrapper. Thus, the combination machine does not have two separate frames, but the baling chamber and the bale wrapper are supported on the same frame. In the above embodiments, the bale wrapper exemplified comprises vertical wrapping arms that rotate about a horizontal axis around a rotating bale. It will be clear to a person skilled in the art that bale wrappers of different construction and operating principle can also be used in the bale wrapper according to the invention. For example, the bale wrapping device may have a wrapping table according to the prior art, which causes the bale resting on it to rotate about both a vertical and a horizontal axis. In this case, the rolls of protective film may be in place attached to the body of the device.
    Some preferred embodiments of the bale wrapper and combination machine according to the invention have been described above. The invention is not limited to the solutions described above, but the inventive idea can be applied in various ways within the limits set by the claims.
