    [0001] [001] The present invention relates, in general, to a belt system and a method for winding a belt strip, including automatically winding the bobbin and / or automatically ejecting the bobbin bobbin. BACKGROUND OF THE INVENTION
    [0002] [002] In the process of transporting one or more items from one location to another, a packer typically places some type of conveyor in a shipping container, such as a cardboard box, together with one or more items to be transported . The conveyor fills, partially or completely, the empty space or the empty volume around the articles in the container. The conveyor prevents or minimizes the movement of items that can be damaged during the transport process. Some wedge materials for commonly used items include plastic airbag bags and converted paper mat.
    [0003] [003] To promote continuous operation, many wedge converting machines, whether producing airbag or paper mat, generate a mat strip, which can be cut or fragmented, to provide wedge sections of articles of desired lengths . When using a conveyor belt to block or wrap a relatively large and / or heavy item during transportation, the conveyor belt can be wound in a coil configuration. The wedge coil of articles can then be placed in the transport container beside, above or below the large / heavy item to be transported. Although reels of wedge products can be produced manually, this procedure can take a considerable amount of time or space, and manual winding can cause unstable properties in the reel. Consequently, automatic winding mechanisms have been developed to address one or more of these other problems.
    [0004] [004] International Patent Application Publication WO 99/21702 describes a system for winding a belt strip, produced by a belt converting machine. A sheet feed material, provided from a roll, is converted into a relatively lower density belt strip, which is then wrapped around a mandrel in a rolled configuration. A joining device for securing the rear end of the belt strip to the bobbin and an automatic bobbin ejection device are both suggested in this publication, but the details of this hypothetical device are neither shown nor described. SUMMARY OF THE INVENTION
    [0005] [005] The present invention provides an exemplary automatic coil splicing device and an automatic wedge coil ejection device for use with a belt conversion machine and a winder, such as those described in the international patent application WO 99/21702, referred to above.
    [0006] [006] More particularly, the present invention provides an automatic joining mechanism, for use with a belt converting machine and a winding mechanism for winding a belt strip. The joining mechanism includes a tape source, and a guide surface, which can be positioned between an outlet of the belt converting machine and the winding mechanism, to orient a belt strip to the winding mechanism. The guide surface also guides a strip of tape for coupling with a rear end of article wedges, to secure the rear end of the belt strip to the bobbin. The guide surface has a groove, for receiving the strip of tape, and an entrance opening in the groove, for receiving the strip of tape from the tape source, the tape source being located on the opposite side of the guide surface opposite the slot.
    [0007] [007] The joining mechanism may also include a cutting mechanism, spaced downstream from the tape inlet, to separate a length of tape from the source, for fixing the rear end of the belt strip.
    [0008] [008] The joining mechanism can be provided in combination with a winding mechanism, which rotates about an axis, to wind the belt strip in a coil. The axis of the winding mechanism is parallel to the guide surface.
    [0009] [009] The joining mechanism can also be provided in combination with a belt converting machine, which converts a feed material into the belt strip to be wound. The belt conversion machine dispenses the belt strip from an outlet, and the guide surface is mounted between the outlet of the conversion machine and the winding mechanism.
    [0010] [0010] The joining mechanism may also include a sensor, adjacent to the tape entry opening, which detects one end of the tape strip.
    [0011] [0011] The present invention also provides a method of producing a mat product, comprising the steps of: (a) providing a mat strip; (b) winding the belt strip in a bobbin; and (c) automatically joining a rear end of the belt strip to an outer surface of the bobbin.
    [0012] [0012] The step (a) of providing may include: (i) providing a sheet feed material, preferably paper, to a belt converting machine; and (ii) converting the sheet feed material into a strip of relatively lower density mat.
    [0013] [0013] In addition to the mechanism and method of joining, the present invention provides an automatic coil ejection mechanism, for use in a system with a belt conversion machine, capable of producing a belt strip and dispensing the belt strip by an outlet, and a winding mechanism, downstream of the outlet, which is capable of wrapping a belt strip around a winding axis, to produce a rolled belt product. The coil ejection mechanism includes a lever arm, having a pivot axis around which the lever arm rotates, between a prepared position and an ejection position. The ejection mechanism also has a push plate, mounted on the lever arm, at a location spaced from the pivot axis. The pusher plate has a surface, which is parallel to a pivoting plane, which includes the pivot axis, where the pivot plane is perpendicular to the coil axis, when the pusher plate is in the prepared position.
    [0014] [0014] The coil ejection mechanism can also include a support structure, in which the lever arm is attached to the pivot shaft.
    [0015] [0015] The coil ejection mechanism can also be provided in combination with a winding mechanism, which rotates around the winding axis, to wind the belt strip onto a coil, and / or in combination with a converting machine belt, which converts a feed material into the belt strip to be wound, and the lever arm is mounted on a frame, which is attached to the conversion machine.
    [0016] [0016] The combination may also include a source of feed material, for conversion into a relatively less dense mat product, such as one or more of a sheet of paper and a sheet of kraft paper.
    [0017] [0017] The coil ejection mechanism can have a winding shaft, which is generally horizontal, and a pivoting shaft, which is generally vertical.
    [0018] [0018] The coil ejection mechanism can also include a driving device, to promote the rotation of the lever arm, to push a coil out of the winding mechanism. An exemplary driving device includes one or more of an electric motor and a clutch.
    [0019] [0019] The present invention also provides a method of producing a mat product, which includes the steps of: (a) providing a mat strip; (b) winding the belt strip in a mandrel, around a winding axis, in a coil; and (c) automatically eject the mandrel spool by pushing the spool in a direction generally parallel to the winding axis.
    [0020] [0020] The process can also include a step (a) of providing, which includes: (i) providing a sheet feeding material to a belt converting machine; and (ii) converting the sheet feed material into a strip of relatively lower density mat.
    [0021] [0021] Other aspects of the invention will be evident from the detailed description presented below, when considered in conjunction with the drawings. BRIEF DESCRIPTION OF THE DRAWINGS

    [0028] [0028] Referring then to the drawings in detail, the present invention provides a wedge conversion system for articles 10, which includes a belt conversion machine 12 (sometimes referred to as a "converter"), a winding mechanism 20 , a joining mechanism 22 and an ejection mechanism 24. The belt converting machine 12 converts a sheet feed material 14, taken from a source 16, into a relatively less dense strip of wedge articles (not shown). The strip exits through an outlet 26 of the converting machine 12 and is wound or coiled in a bobbin by the winding mechanism 20, and a rear end of the belt strip is automatically attached to the bobbin by the joining mechanism 22. The finished bobbin is automatically ejected from the winding mechanism 20 by the coil ejection mechanism 24.
    [0029] [0029] The illustrated source of feed material 14 includes a mobile cart 30, with one or more pairs of laterally spaced arms 32, capable of supporting one or more rolls 36 of sheet feed material 14. In this case, only one roll 36 of feed material 14 is shown, supported on the arms 32 by a transverse axis 38, although a second pair of arms 32 is present and can support a second roll of sheet feed material (not shown) on a corresponding axis 38 An exemplary sheet feed material 14 is kraft paper, and kraft paper can be supplied rolled up in a roll, as shown, or provided in a fan-folded pile.
    [0030] [0030] During the conversion process, the belt conversion machine 12 internally collects the sheet feed material 14 and deforms it to form a belt strip, which is relatively less dense than the sheet feed material 14, from which it is produced. In the illustrated belt conversion machine 12, the sheet feed material 14 moves by a forming mechanism 40, which includes a track 42, which converges in a direction downstream of a track inlet 44 to a relatively smaller track outlet 46, internally gathering the sheet feed material and deforming it as it passes through the chute 42. The deformed feed material then passes through a feed / connection mechanism 50, downstream of the forming assembly 40, which both feeds the material feed by the converting machine 12 and links the overlying layers of sheet feed material to assist in maintaining the shape of the finished mat strip. Once a desired length of wedge of articles has been produced, a separator mechanism 54, downstream of the feed / connection mechanism 50, separates the completed mat strip from the sheet feed material 14 of the source 16. The present invention does not it is limited, however, to the illustrated belt conversion machine 12, and any belt conversion machine, which converts a sheet feed material to a relatively lower density belt length or strip, can be used in that system 10 .
    [0031] [0031] The illustrated belt conversion machine 12 is mounted on a platform 56, which has wheels 58 for mobility, although any type of support for the belt conversion machine 12 can be provided, as may be necessary to support the conversion machine 12 and the winding mechanism 20, at a height sufficient to produce a coil.
    [0032] [0032] The winding mechanism 20, sometimes referred to as a winder, is downstream of the belt conversion machine 12 and is supported by a frame extension 62, mounted on the frame of the belt conversion machine 12 or on the platform 56 The illustrated winder 20 includes a mandrel, around which the belt strip is wound. In the illustrated embodiment, the winder 20 includes a rotating fork 64, with a pair of teeth 66 substantially parallel, between which a leading end of the belt strip is received. Once a wedge feed end passes between the teeth 66 of the fork 64, the fork 64 can rotate to wrap the belt strip in a bobbin as the belt strip is produced. The belt strip is produced at a constant speed, but the rotation speed of the fork 64 can be varied depending on the size of the spool, to vary the density, consistency and other properties of the spool.
    [0033] [0033] A guide surface 70 extends from the outlet 26 of the belt conversion machine 12 towards the winding mechanism 20, to guide a strip of belt from the outlet 26 to the winding fork 64. A spring-driven part 72 of the the guide surface, adjacent to the winding fork 64, is spring-loaded and rotates about an axis 74, spaced from the winding fork 64 in a direction away from the winding fork 64, as the coil grows and expands out. Another reference to the exemplary belt converting machine and winder can be made with reference to the publication of the international patent application WO 99/21702, referred to above. Alternative winder designs can also be used in this system 10; the system 10 provided by the invention is not limited to the illustrated winder 20.
    [0034] [0034] Once a desired length of wedge of articles has been produced, the separator mechanism 54, on the belt converting machine 12, will cut the belt strip of the remaining feed material. The winding fork 64 will stop and then continue to rotate to pull the rear edge of the belt strip onto the bobbin. In the past, tape was applied manually to the rear end of the belt strip, to secure the rear end to the bobbin, in order to maintain the bobbin shape. This required an operator to handle the sticky tape, which was inconvenient for the operator, caused errors, inconsistent tape usage, and losses.
    [0035] [0035] To consider these and other problems, the wedge conversion system for articles 10, provided by the invention, includes an automatic joining mechanism 22. The converter 12 will signal to the winding fork 64 to interrupt and start based on the status of its supply / connection mechanism 50. Specifically, converter 12 will interrupt its supply / connection mechanism 50 and the winding fork 64, before activating the separator mechanism 54. After the separator mechanism 54 has separated the belt strip of the supply material connected to the source, the winding fork 64 is reset. The automatic joining mechanism 22 also includes a separating mechanism, such as the illustrated punch element 114. The punch element 114 breaks a portion of the tape, without using a sharp cutting edge. The other side of the hole punch 94, part of the pivoting body 112, is also used to compress the rear end of the mat strip in coupling with an adhesive surface of the tape 92. Once a desired length of the tape has advanced to secure the rear end of the strip on an outer surface of the bobbin, the punch element 114 can itself separate a length of tape 92 from a tape source 96 by perforating the tape 92.
    [0036] [0036] The tape source 96 is mounted underneath the converting machine 12, and the tape 92 is pulled into the slot 102 of the source 96 and fed through one end of the guide surface 70, or through an opening 104, in the surface of guide 70, for example, in the manner shown in the illustrated embodiment. To minimize friction between the belt strip, leaving the belt converting machine 12, and the adhesive surface of the tape 92, where the guide surface forms part of the joining mechanism 22, a tape guide part of the surface of the guide 70 has side parts 100, which are raised above a central part, which forms a groove or a groove 102. The leading end of the tape 92 rests on this groove 102, with the adhesive side up. The arrival of the rear end of the belt strip, signaled by the converting machine 12, causes the other side of the hole punch 94, on the pivot body 112, to advance and compress the rear end of the strip in coupling with the adhesive surface. Then, the winding fork 64 will restore the winding of the belt strip to a bobbin, and pull the ribbon 92 from the joining mechanism 96. The ribbon 92 is wound around the produced bobbin and keeps the belt strip in the wound condition.
    [0037] [0037] Punch 94 includes a solenoid 110, or other driving device, connected to a pivoting body 112, of which a puncturing element 114 extends to a spaced point from a pivot axis 116. As far as solenoid 110 extends and drives the punch element 114 downwards, the leading end of the punch element 114 and the pivoting body will separate the tape 92.
    [0038] [0038] A length of tape will be pulled after the rear end of the belt strip. After the ribbon 92 has been successfully wrapped around the rolled strip, the punch 94 advances and punctures the ribbon 92, and the punch element 114 is received in an opening 120 in the guide surface 70. The punch element 114 drills a hole in the tape 92 thereby weakening tape 92 so that it will automatically tear as tape 92 is pulled together by the rear end of the belt strip. The tension on the axis of the tape source 96 can be adjusted to facilitate tearing, causing the tape to tear prematurely.
    [0039] [0039] As the rear end of the belt strip is wound onto the bobbin, the spring-actuated part of the guide surface 70 will compress the ribbon 92 on the adjacent surface of the bobbin, to secure the rear end of the belt strip to the coil, so that the coil maintains its shape. The joined coil is thus complete and ready for use.
    [0040] [0040] The coil ejection mechanism 24 then pushes the completed coil out of the fork 64. The ejection mechanism 24 includes an ejection plate 122, adjacent to the winding fork 64, which has a relatively large surface area to the coil, for couple and push the bobbin out of the winding fork 64. The surface of the ejector plate 122, facing the winding fork 64, is formed to allow it to pass through the winding teeth 66 as it pushes the bobbin out of the winding fork 64. The pushing surface 124 is secured to a lever arm 126, which has a pivoting axis 128 generally transverse to the axis of the coil 130, around which the winding fork 64 rotates. The pivot shaft 128 is spaced from the winding fork 64, approximately adjacent to the outlet 26 of the conversion machine 12, and another solenoid, or other driving device, 129 acts on the lever arm 126, on one side of the pivot shaft 128, to pivot the pushing surface 124, on the other side of the pivoting shaft 128, in the direction of a distal end of the winding fork teeth 66, for sliding the rolled article wedge strip out of the teeth 66 of the fork 64. The lever arm 126 and the ejector plate 122 move pivotally between a prepared position, which allows the winder 20 to produce a rolled strip, and an ejection position, which pushes the bobbin out of the ends of the teeth 66 of the fork 64, in a generally direction parallel to the winding shaft 130. An operator can then place the rolled wedge strip of articles in a box, or other container, for packaging purposes.
    [0041] [0041] The system provided by the present invention is thus improved in relation to the prior art systems, which wrap wedge strips of articles on a reel, providing an automatic joining mechanism for applying tape to a rear end of the strip of mat, to adhere the rear end of the strip to the bobbin, thereby maintaining the belt strip in the rolled-up configuration. The present invention is further perfected in relation to prior art systems by providing an automatic coil ejection mechanism, to remove the rolled article wedge strip from the winding mechanism, using a pivotally mounted push plate, to leverage the article wedge rolled out of the winding mechanism. This system allows the packer, or another operator, to concentrate on packing items in a container, instead of applying tape and removing shim reels from articles. This increases the efficiency of a packaging operation, which uses a joining mechanism, and reduces losses. In summary, the present invention provides a wedge conversion system for articles 10, which includes a machine 12 for converting a feed material 14 into a strip of relatively lower density, a winding mechanism 20 for wrapping the strip around a spool, a splicing mechanism 22 to automatically attach a rear end of the strip to the spool, and a spool ejection mechanism 24 to automatically remove the spool from the winding mechanism 20. The splicing mechanism 22 includes a guide surface 70, between an outlet 26 of the machine 12 and the winding mechanism 20, to orient the strip to the winding mechanism 20 and orienting the tape 92, for coupling with a rear end of the strip on the bobbin. The bobbin ejection mechanism 24 includes a lever arm 126, which pivots to push the complete bobbin out of the winding mechanism 20.
