Description

  The present invention relates to a disassembly grab used when disassembling a wrapping package. The present invention also relates to a disassembling apparatus provided with such a disassembling grab for a wrapping package, and a wrapping package processing system including the disassembling apparatus.

  Conventionally, a wrap package in which the outer surface of a roll bale roll-formed with a roll baler is packed with a wrap material is known. Since this wrap package is excellent in handling such as storage and transportation, its utilization is also considered when packing livestock feed crops and fully-ripened compost.

  By the way, since such a wrap package generally has a large diameter of 1 meter or more and a large weight, it may be difficult to carry or disassemble it. Therefore, the present applicant has previously proposed a tractor-mounted roll bale disassembly grab used in grasping and dismantling of a wrapping package in Japanese Patent Application Laid-Open No. 2006-42688 (Patent Document 1). When the wrapping packing body is gripped between a pair of gripping arms, the disassembling grab can pierce the wrapping packing body with a spike projecting from the inside of the gripping arm and reliably lift it.

  However, in the disassembling grab having the conventional structure described in Patent Document 1, it is necessary to cut the roll bale wrap member gripped between the pair of gripping arms with a cutter or the like when the wrap package is disassembled. Therefore, there is a problem that the efficiency of the dismantling operation of the wrapping package is poor and there is a risk that the dismantling operation may be dangerous.

  Moreover, even if the wrapped wrap member gripped between the pair of gripping arms is cut with a cutter or the like and the packaged feed or compost can be taken out, the spikes protruding from the gripping arms are attached to the wrap member. It stays stuck. Therefore, this wrap member has to be further manually removed from the gripping arm, and there is a problem that much labor and time are required for the operation.

In the present embodiment, the hydraulic cylinder 66, the interlocking shaft 62, the gear mechanism (not shown), and the connecting plate 68 constitute an interlocking control means.

  Then, the wrap package processing system provided with such a demolition apparatus 12 is demonstrated. The wrapping package processing system includes a roll baler 76 and a bale wrapper 78 for manufacturing the wrapping package 74 to be disassembled by the disassembling apparatus 12.

  As shown in FIG. 6, the roll baler 76 includes a chamber 82 having a substantially cylindrical gap for creating the roll bale 80. In the chamber 82, a plurality of driven shafts 84 each having a cylindrical outer peripheral surface with sprockets (not shown) attached to both ends in the axial direction are arranged in parallel over substantially the entire circumference of the chamber 82. Yes. A rotational driving force of a motor (not shown) is transmitted to each driven shaft 84 by a drive chain 86 (see FIG. 7) attached to the sprocket. As a result, each driven shaft 84 is driven to rotate in the same circumferential direction, and a large number of fully matured compost as wet fine granular objects sent from the inlet 88 into the chamber 82 are driven shafts 84. The roll bale 80 is formed by being compressed into a cylindrical shape while being rotated.

  In particular, in this embodiment, as shown in FIG. 7, the side pressure portions 90 are provided on the side wall portions located on both sides in the axial direction of the chamber 82. The side pressure portion 90 has a fan shape in a plan view, and moves upward in the height direction of the chamber 82 (that is, the object (injected into the chamber 82 by the rotation of the plurality of driven shafts 84) ( An inclined surface 92 is formed which gradually goes inward in the width direction of the chamber 82 as it goes forward in the circumferential direction in which the fully matured compost is sent. As a result, the matured compost that is fed into the chamber 82 and rolled in the circumferential direction by the rotation of each driven shaft 84 in the chamber 82 can be compressed in the width direction (axial direction) of the chamber 82. . As a result, ripe compost can be packed with high density.

  Further, the roll bale 80 formed in the chamber 82 is discharged rearward when the door portion 94 constituting the rear side wall portion of the chamber 82 rotates about one axis. In addition, the net is wound around the outer peripheral surface of the roll bale 80 discharged | emitted back like the past.

  Behind the roll baler 76, a bale wrapper 78 is disposed. As shown in FIG. 8, the bale wrapper 78 is suspended in a state in which the film rotor 100 can rotate about one axis with respect to the rear end portion of the gate 98 protruding above the main body frame 96. The structure is made.

  A stage 102 on which the roll bale 80 is placed is provided below the film rotor 100. The stage 102 has a structure in which a belt 106 is looped around belt wheels 104a and 104b provided at both ends, and the driving force of the drive motor 108 is transmitted to the belt wheel 104a to move the belt 106. It has become. The stage 102 is attached to the main body frame 96 so as to be swingable around one axis around the belt wheel 104a located on the rear side.

  In the present embodiment, the belt 106 is stretched around the belt wheels 104a and 104b so that the portion of the belt 106 where the roll bale 80 is placed sinks downward. Thus, even if the upper portion of the belt 106 is moved from the front to the rear, the roll bale 80 placed on the belt 106 can be positioned between the two belt wheels 104a and 104b. It has become.

  Further, a conveyor mechanism 110 is provided in front of the stage 102 in the bale wrapper 78. The conveyor mechanism 110 has a structure in which a belt 114 is looped around belt wheels 112a and 112b provided at both ends. Then, the conveyor mechanism 110 conveys the driving force of the driving motor 116 to the belt wheel 112a and moves the belt 114, thereby conveying the roll bale 80 placed on the belt 114 to the stage 102 without rotating. ing.

  The conveyor mechanism 110 is provided with a height position adjusting mechanism 118 that adjusts the height position of the belt 114. Thereby, the height position of the belt 114 can be adjusted according to the discharge position of the roll bale 80 in the roll baler 76. As a result, it is possible to avoid the collapse of the side surface (the end surface in the axial direction) due to the drop impact received when the roll bale 80 is released from the roll baler 76.

  The roll bale 80 conveyed by the conveyor mechanism 110 as described above is placed on the stage 102 (belt 106) by swinging the stage 102 downward. Then, the stage 102 on which the roll bale 80 is placed is leveled, the belt 106 is moved by the drive motor 108 and the roll veil 80 is rotated around the central axis, and the film rotor 100 is rotated by the drive motor 120. Thereby, the wrap material 124 constituting the film roll 122 provided at the tip of the film rotor 100 is wound around the roll bale 80 placed on the stage 102. As a result, a wrap package 74 in which the roll bale 80 is packed with the wrap material 124 is manufactured. The manufactured wrap package 74 is discharged rearward by swinging the stage 102 upward.

  The wrap package 74 manufactured as described above is stored outdoors or in an appropriate place such as a warehouse, and is then transported to the field by a truck or the like. The wrap package 74 that has been transported to the field is disassembled by the disassembly device 12.

  Subsequently, a method of disassembling the wrap package 74 by the disassembling apparatus 12 will be described based on FIGS. 9 and 10. In FIG. 9, the dismantling grab 10 is shown as a model.

Further, the saw blade 46 provided on the swinging portion 42 of the cutter 40 bites into the wrap packing body 74. Moreover, the slide part 44 moves in the circumferential direction of the wrap packing body 74 by moving the slide part 44 of the cutter 40 forward (a direction away from the grab base member 18). Thereby, the saw-tooth 48 of the slide part 44 cuts the wrap packing body 74 partially.

  Thereafter, as shown in FIG. 9C, the other inner gripping arm 26b is swung to one side in the swinging direction, and one gripping arm member 20a is further moved inward in the swinging direction. As a result, the wrap packing body 74 is pushed away from the grab base member 18 by the inner gripping arm 26b in a direction approaching the cutter 40, the presser piece 64 bites into the wrap packing body 74, and the spike pin 60 is lowered. The wrap packing body 74 is pierced while moving from the side to the upper side. Further, the sawtooth 46 provided on the swinging portion 42 of the cutter 40 further bites into the wrap packing body 74, and the slide portion 44 of the cutter 40 moves inwardly in the swinging direction together with the gripping arm member 20a. As a result, the cut formed in the wrap package 74 is further expanded, and the contents (completely composted) of the wrap package 74 are removed from the cut formed on the outer surface of the wrap package 74 as shown in FIG. It is designed to fall down.

  When the contents of the wrap package 74 are dropped, as shown in FIG. 10D, the wrap package 74 is moved in a state where the wrap material 124 and the net constituting the wrap package 74 are held. In this state, the pair of gripping arm members 20a and 20b are closed, and the other inner gripping arm 26b is moved to one end side in the swinging direction.

As a result, the wrap material 124 and the net constituting the wrap package 74 are locked to the spike pins 36 and 60 so that the wrap material 124 and the net constituting the wrap package 74 do not fall.

  And if it moves to the place which discards the lap | wrap material 124 and net | network which comprise the wrap packing body 74, as shown to FIG.10 (e), while opening a pair of holding | grip arm member 20a, 20b, the other inner side holding | grip The arm 26b is moved to the other end side in the swinging direction. As a result, the spike pins 36 and 60 hang downward, and the state where the wrap material 124 and the net constituting the wrap packaging body 74 are locked by the spike pins 36 and 60 is released. As a result, the wrap material 124 and the net constituting the wrap package 74 fall to the disposal site.

  In the disassembling apparatus 12 as described above, the operation of partially cutting the wrap package 74, which is performed when taking out the contents of the wrap package 74, uses the cutter 40 provided on one gripping arm member 20a. Therefore, the wrapping package 74 can be disassembled quickly and reliably without manual operation.

  Further, since the guide plate 52 is bolted to the one inner gripping arm 26a, the cutter 40 cannot be disposed on the one inner gripping arm 26a if the guide plate 52 is removed. In this case, since the wrap packing body 74 is not damaged by the cutter 40, the wrap packing body 74 using the disassembly device 12 is not hindered in transportation.

  Further, since the movements of the spike pin 36 and the outer gripping arm 24a are interlocked, the spike pin 36 is securely attached to the wrapping packing body 74 when the wrapping packing body 74 is gripped by the pair of gripping arm members 20a, 20b. Can be pierced. Therefore, the gripping state of the wrap package 74 by the pair of gripping arm members 20a and 20b can be stabilized.

  Further, since the movement of the spike pin 60 and the other inner gripping arm 26b is interlocked, when the wrap packing body 74 is cut by the cutter 40, the spike pin provided on each of the pair of gripping arm members 20a and 20b. 36 and 60 pierce the wrap member 124 and the net constituting the wrap package 74. Thereby, when the wrap packing body 74 is cut by the cutter 40 and the contents of the wrap packing body 74 are dropped, the wrap member 124 and the net constituting the wrap packing body 74 can be prevented from dropping.

  In particular, since the spike pin 60 pierces the wrap packing body 74 while moving from the lower side to the upper side, it is possible to effectively prevent the wrap member 124 constituting the wrap packing body 74 and the net from dropping.

  By the way, five wrapping packages 74 packed with fully-ripened compost having a moisture content of 45.6% during packaging were dismantled. The average disassembly time in that case is 87.2 seconds. The breakdown is 5.2 seconds for gripping, 3.2 seconds for cutting, 75.4 seconds for dismantling, and 3.4 seconds for recovery. The cutting rate indicating the cutting ratio with respect to the circumferential direction of the roll veil is 76.1%. The original loss rate indicating the fully matured compost attached to the net wound around the outer periphery of the roll bale is 3.0%. The compost particle size distribution is 49.1% below 1 cm, 32.5% above 1 cm and below 5 cm, and 18.4% above 5 cm.

  As is clear from this, when the disassembling apparatus 12 is used, the disassembling work of the wrap package 74 can be quickly performed.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited by the specific description. For example, in the above-described embodiment, the dismantling operation of the wrapping packing body 74 in which the mature compost is packed is described. Of course, it is possible.

  Moreover, you may provide the slope for rolling the wrap packing body 74 discharge | released from the bail wrapper 78 back.

  A commercially available shredded roll baler may be used instead of the roll baler 76 having a structure in which a plurality of driven shafts 84 are provided on the circumference as described above. Also in this case, like the above-described side pressure portions 90, 90, a compression region in which the axial interval gradually becomes narrower toward the front in the rotational circumferential direction by exhibiting a fan shape or the like with respect to the side wall portion of the chamber. It is effective to attach a side pressure plate that forms the plate. Thereby, like the said embodiment, a roll bale can be rounded and formed in the circumferential direction, compressing in an axial direction.

  Further, a conveyor mechanism extending in the direction of discharging from the bale wrapper 78 may be provided. Thereby, it is possible to form a conveyor conveyance path from the roll bale 80 to the bale wrapper 78 until the completed wrap package is discharged, and the roll bale is wrapped in the conveyance path (distribution path). It becomes possible.

  In the above embodiment, the spike pin 36, the cutter 40, and their drive mechanism may be attached to the outer gripping arms 24a and 24b without providing the inner gripping arms 26a and 26b.

  In addition, the spike pin 36 is provided only on one side of the pair of gripping arms, or the spike pin is provided at different positions with respect to one gripping arm. Is not particularly limited. Furthermore, the cutter 40 may be provided on both gripping arms, and an electric motor, a hydraulic cylinder, or the like may be specially provided as a driving means. Further, as the cutter, in addition to the sawtooth shape as illustrated, a cutter having various structures such as a straight blade knife-like cutter can be appropriately employed depending on the material of the wrap member.

  In addition, spike pins and cutters can be driven by different actuators, and the present invention can also be realized by manual operation in which each of these separate operation switches is provided to switch the operation manually. It is.
