Description

  The present invention relates to a workpiece stacking apparatus that transports a bag-packed compressible bag-packed workpiece while compressing and stacks a plurality of the bag-packed workpieces.

  Examples of the compressible work include tissue paper and paper diapers packed in a bag. A boxing device for boxing such workpieces is described in Patent Document 1 below. FIG. 7 is a plan view showing the entirety of the boxing device disclosed by the same document. In the boxing device 100, the tissue folded by the tissue folding machine 101 is wrapped by the packaging machine 102, and the wrapped tissue W in the horizontal state is supplied to the reversing device 103. In the reversing device 103, the wrapped tissue W is reversed, is brought upright, and is conveyed to the pusher 112 by the delivery belt 111.

  The packed tissue W is pushed out to the counting unit 104 by the pusher 112, and the belt moves at a high speed when the predetermined number is reached, and is compressed and accumulated so as to have a predetermined width. At that time, the entire counting unit 104 is sucked by the air suction hose 113 so that the wrapped tissue W in the standing state does not fall down. A predetermined number of packaged tissues W are pushed out to the accumulating unit 105 by the pusher 114 and accumulated in a close contact state without generating a gap therebetween. Then, the lower end side is compressed by the collecting plate 115 from both sides in the collecting direction, and the wrapped tissue W held in a bridge shape is lowered to an appropriate position and inserted into the box 116 in a compressed state.

  In the boxing device 100, the packed tissue W is compressed when it is sent to the counting unit 104 and stopped by a stopper (not shown). The compression is performed such that the bundle of the stacked packaged tissues W falls within a predetermined width. However, in the conventional example such as the boxing device 100, since the flat packaged tissue W moves in an upright posture, the air is re-entered into the bag from which the air has been removed by the compression, and then swells. If so, it is necessary to keep the packed tissue W in a compressed state at all times, but this complicates the structure of the apparatus.

  Therefore, in order to solve this problem, the present invention transports a packed packed compressive work piece while compressing it, and stacks a plurality of the packed work pieces in a compressed posture. An object is to provide an apparatus.

  The workpiece stacking device according to the present invention is a flight plate that moves up and down the bag-packed workpiece sent from a conveyor for a bag-packed workpiece in which a compressible content is packed in a bag having an exhaust hole. A plurality of layers are stacked on top of each other, provided in the conveying direction of the bagging work, and are pressed through a plurality of rollers at predetermined intervals so as to sandwich and compress the bagging work from above and below. And a pair of upper and lower pinch rollers sandwiching the bagging work on the exit side in the conveying direction, the upper press conveyor and the lower press conveyor The pressing belt rotates at the same rotational speed as the conveyor, and the pinch roller causes the bagging work to fly to the flight plate side. Characterized in that it is intended to rotate in a possible speed.

Further, in the workpiece stacking apparatus according to the present invention, the upper press conveyor has its pressing belt slanted at the entrance portion in the conveying direction, and the upper press conveyor and the lower press conveyor It is preferable that the distance between the upper and lower surfaces of the working belt is narrowed toward the exit side in the conveying direction.
Moreover, as for the workpiece | work stacking-up apparatus which concerns on this invention, it is preferable that the said upper side press conveyor is a thing whose exit side dimension of a conveyance direction is shorter than the said lower side press conveyor.
In the workpiece stacking device according to the present invention, the flight plate is lowered stepwise by a predetermined distance according to a set thickness of the bagging workpiece compressed by the upper press conveyor and the lower press conveyor. It is preferable.

  According to the workpiece stacking device of the present invention, since the rotation of the pressing belt is about the same as that of the conveyor and the conveying speed is reduced, the compression time of the bagging workpiece is increased, and the thickness is reduced to the set value. can do. And the bagging workpiece | work compressed on the frying board can be appropriately stacked | stacked by flying a bagging workpiece | work to the flight board side with the attitude | position compressed by the pair of upper and lower pinch rollers rotating at high speed.

It is the side view which showed notionally an example of the workpiece stacking apparatus. It is the figure which showed the state in which the bagging workpiece | work was caught by the guide. It is the figure which showed the state from which the position of the upper surface of the bagging workpiece | work in the uppermost part of a stacking part became high. It is the side view which showed conceptually one Embodiment of the workpiece stacking apparatus. It is the side view which showed more specifically the product stage conveyor part of the product stage conveyor shown in FIG. It is the figure which showed the lift mechanism which adjusts the height of the flight board. It is the top view which showed the whole about the conventional boxing apparatus.

  Next, an embodiment of a workpiece stacking device according to the present invention will be described below with reference to the drawings. The bagging work handled in this embodiment is a normal size tissue paper, which is packed in a bag made of polyethylene or polypropylene instead of a box. The workpiece stacking device is provided on the upstream side of a packaging machine that stacks a plurality of flat-shaped bagging workpieces and packs them together. In the present embodiment, five bag-packed workpieces are stacked to form a bundle.

  At that time, in order to reduce the thickness of the bagging work one by one and reduce the total height when the five pieces are bundled, the bagging work is compressed to extrude air in the bag as well as to fold tissue paper. Therefore, the workpiece stacking device of the present invention is configured to convey a flat bag-packed workpiece while pressing it in the vertical direction. FIG. 1 is a side view conceptually showing an example of such a workpiece stacking device.

  This workpiece stacking device 80 is configured as a belt-type press conveyor as a stacking conveyor, and as shown in the figure, an upper press conveyor 81 that conveys a bag-packed workpiece W and a lower press conveyor that is installed facing the upper press conveyor 81. 82 is arranged.

  By the way, the tissue paper of the bagging work W is folded and bundled by a predetermined number, but the thickness thereof is not always constant. This is because the folding is not sufficient and not only is it affected by moisture, but also the bag contains a lot of air. For this reason, even if the thickness of the bagging workpiece W is set to 50 mm, an error may occur with a width of about 10 mm. In order to correct such an error, the workpiece stacking device 80 folds the tissue paper by compression and adjusts the thickness of the bag-packed workpiece W by removing air from the bag. In addition to the perforation, the bagging workpiece W is formed with extremely fine holes as exhaust holes, and the air inside is discharged when pressed.

  In the workpiece stacking device 80, the pressing belts 811 and 821 of the upper and lower press conveyors 81 and 82 are stretched so as to face each other at a predetermined interval. A plurality of rollers 812 and 822 are respectively arranged on the upper and lower sides, and an interval (for example, 50 mm) through which the bagging work W passes is set. Although not shown, the upper and lower press conveyors 81 and 82 are each provided with a drive motor so that the rotation is transmitted to the press belts 811 and 821.

  Since the bag filling work W contains air, if it is suddenly pressed, the internal pressure increases and the perforation of the bag is broken. Therefore, the workpiece stacking device 80 has a belt for pressing the upper press conveyor 81 so that the width of the entrance portion gradually narrows in the conveying direction so that the bag-packed workpiece W can smoothly enter. 811 is slanted. Further, although the distance between the pressing belts 811 and 821 facing the upper and lower sides is very small, it is narrower toward the outlet side (right side of the drawing).

  Such a product stage conveyor is provided with a product stage 85 on the downstream side. The stacking step portion 85 is partitioned by the abutting plate 86 and the side plate 87, and is configured so that the bagging work W is stacked on the flight plate 88. The flight plate 88 can be adjusted in height by a lift mechanism (not shown), and is lowered stepwise in response to the feeding of the bagging workpiece W. This is to stabilize the stacked state of the bagging workpieces W by accepting the bagging workpieces W from the stacking conveyor at substantially the same height.

  By the way, in the workpiece stacking apparatus 80, the upper and lower press conveyors 81 and 82 convey the bagging workpiece W at a speed about three times as high as the conveyance speed of the conveyance conveyor 79 that feeds the bagging workpiece W. This is because the bagging work W is ejected vigorously on the outlet side, and the bagging work W is overlapped as shown in the figure, while flying to the stacking step 85 while maintaining the horizontal posture. Accordingly, if the pop-out speed at the time of discharging is slow, the momentum is so weak that the bagging workpiece W does not reach the abutting plate 86, so that the rear end of the bagging workpiece W is caught by the guide 89 as shown in FIG. If the flight plate 88 is lowered, the bagging work W is inclined obliquely and cannot be correctly stacked as shown.

  On the other hand, on the stacking step 85 side, the landing height is adjusted by position control of the flight plate 88 so that the bag-filled workpiece W that has popped out is received in an almost unchanged posture. Specifically, it is preferable that the height difference h between the upper surface of the uppermost bag-packed workpiece W stacked on the stacking step portion 85 and the lower surface of the bag-packed workpiece W stacked next is as narrow as possible. . Therefore, the flight plate 88 is configured to descend one step each time one bag-packed workpiece W is received, and the descending distance has a dimension (for example, 53 mm) corresponding to the set thickness (for example, 50 mm) of the bag-packed workpiece W. Is set.

  If the descending distance for one step (for example, 60 mm) is too large, the difference from the workpiece thickness (about 10 mm) is accumulated, and the last bag-packed workpiece W (for example, the fifth one in the case of 5 packs) is accumulated. When thrown into the stepped portion 85, the depth becomes, for example, 40 mm. Then, as shown in FIG. 2, the upper surface of the uppermost bag-packing work W stacked on the stacking step portion 85 is lowered, and then the bag-working work W jumped out from the upper and lower press conveyors 81 and 82 falls vertically. There is a possibility that the product will not be moved to the packing process, resulting in a stacking error.

  Further, in order to reduce the integrated dimension, it is conceivable to match the distance for one step in which the flight plate 88 descends with the set thickness of the workpiece W. However, since the thickness of the bagging workpiece W that has passed through the upper and lower press conveyors 81 and 82 is not necessarily constant, the thickness dimension of the bagging workpiece W may be larger than the descending distance of the flight plate 88. is there. Then, as shown in FIG. 3, the upper surface of the uppermost bag-packed workpiece W stacked on the stacking stage 85 becomes high, and overlaps with the entry height of the next-packed workpiece W to be sent. And the bag packing work W which jumped out from the upper and lower press conveyors 81 and 82 hits, and a stacking stage error arises.

  Such a problem may occur even when the flight plate 88 is lowered with a certain margin with respect to the lowering distance for one step. In the workpiece stacking device 80, the bagging workpiece W is not sufficiently compressed in the upper and lower press conveyors 81 and 82, and the tissue paper cannot be sufficiently folded and the air cannot be sufficiently removed. This is because may become more than the set value. In particular, in the case of the workpiece stacking device 80, the bagging workpiece W passes through the upper and lower press conveyors 81 and 82 in a short time, so that sufficient compression cannot be performed and a stacking error is likely to occur.

  Next, a workpiece stacking device for reducing product stacking errors is proposed. FIG. 4 is a side view conceptually showing an embodiment of such a workpiece stacking device. This work stacking device 1 has a belt-type press conveyor for compressing and transporting flat-shaped bag-packed works W as in the embodiment of FIG. 1, and the upper press conveyor 3 and the lower press conveyor 4 A conveyor is configured. Further, in the present embodiment, a pair of upper and lower pinch rollers 5 and 6 are provided on the outlet side.

  The workpiece stacking device 1 is a device that compresses the upper press conveyer 3 and the lower press conveyer 4 to strongly fold the tissue paper, and reduces the thickness of the bag-packed workpiece W by extruding air in the bag. is there. The upper and lower press conveyors 3 and 4 are stretched so that the respective press belts 11 and 12 face each other at a predetermined interval. A plurality of rollers 13 and 14 are respectively arranged in the vertical direction, and an interval through which the bagging workpiece W passes is set.

  Since the bag filling work W contains air, if it is suddenly pressed, the internal pressure increases and the perforation of the bag is broken. Therefore, the workpiece stacking apparatus 1 is arranged so that the upper and lower widths are gradually narrowed toward the conveyance direction so that the bag-packed workpiece W can smoothly enter the upper and lower press conveyors 3 and 4. The pressing belt 11 of the press conveyor 3 is inclined. Further, the distance between the press belts 11 and 12 facing the top and bottom is also small but narrows toward the outlet side (the right side of the drawing).

  The upper and lower press conveyors 3 and 4 are each provided with a drive motor (not shown) and configured to transmit the rotation to the press belts 11 and 12. Further, the pair of upper and lower pinch rollers 5 and 6 are also provided with drive motors (not shown), respectively, to be rotated. In this embodiment, the number of rotations of the press belts 11 and 12 is reduced to a low speed so that the conveyance speed is about the same as that of the upstream conveyance conveyor 7, while the number of rotations of the pinch rollers 5 and 6 is increased.

  This is because the bag-packed workpiece W is sufficiently compressed over time by passing between the upper and lower press conveyors 3 and 4 at a low speed. However, if it is discharged at a low speed, the momentum to fly to the product stage cannot be obtained. Therefore, by providing the pinch rollers 5 and 6, the bagging work W is distinguished from the compression to the discharge to the product stage 20, and the pinch rollers 5 and 6 add momentum to the bagging work W by high speed rotation. It was made possible to fly up to the product stage 20 while maintaining a horizontal posture.

  A product stage 20 is provided on the downstream side (right side of the drawing) of the upper and lower press conveyors 3 and 4. The stacking step 20 is partitioned by the abutting plate 21 and the side plate 22, and the bagging work W is stacked on the flight plate 23. The flight plate 23 can be adjusted in height by a lift mechanism (not shown), and is configured to descend stepwise in accordance with the number of stacked bagging workpieces W. This is because the bagging workpieces W from the upper and lower press conveyors 3 and 4 are received at substantially the same height so that the bagging workpieces W can be stably stacked.

  Therefore, according to the workpiece stacking device 1 of the present embodiment, stacking of the bag-packed workpieces W is performed as follows. First, the bag-packing workpiece W is sent via the transfer conveyor 7 and enters the workpiece stacking device 1. The bag filling work W is placed on the pressing belt 12 of the lower press conveyor 4 and is gradually pressed from above by the inclined pressing belt 11 of the upper press conveyor 3. The bagging work W thus compressed in the vertical direction is strongly folded into the tissue paper, and the air in the bag is pushed out. In particular, since the workpiece stacking device 1 has a slow rotation of the pressing belts 11 and 12, the compression time of the bag-packed workpiece W is long. Therefore, the folding is strongly applied to the tissue paper, the air in the bag is also firmly pushed out, and the thickness of the bagging work W can be reduced to almost the set value.

  Subsequently, the compressed bagging work W is sandwiched between the pinch rollers 5 and 6 and is moved forward by the high speed rotation. The bag-packed work W discharged vigorously hits the abutting plate 21 and falls onto the flight plate 23. The first piece is directly placed on the flight board 23, and the second to fifth pieces are sequentially stacked on the bagging workpiece W. At that time, the flight plate 23 descends by a predetermined dimension every time one bag-packing workpiece W is mounted, and receives the bag-packing workpiece W blown by the pinch rollers 5 and 6 at substantially the same height. Then, the five stacked bags W are pushed toward the packing machine by a pusher (not shown).

  Next, the configuration of the workpiece stacking device 1 will be specifically described. FIG. 5 is a side view showing more specifically the product stage conveyor portion of the product stage conveyor 1 shown in FIG. Therefore, the same components as those in the embodiment shown in FIG. First, as described above, the product-stage conveyor has a belt-type press conveyor that compresses and conveys a flat bag-packing work W, and includes an upper press conveyor 3 and a lower press conveyor 4, and the conveyance direction thereof. A pair of upper and lower pinch rollers 5 and 6 are provided at the outlet.

  The upper and lower press conveyors 3 and 4 are provided with press conveyor motors 31 and 32, respectively, and are configured to transmit rotation to the rotation transmission rollers 35 and 36 via timing belts 33 and 34, respectively. The belts 11 and 12 for press are wound around the rotation transmission rollers 35 and 36. The press belts 11 and 12 are provided with tension rollers 37 and 38 in addition to a plurality of rollers 13 and 14 arranged on the upper and lower sides, respectively, so that the tension of the press belts 11 and 12 can be adjusted. The pair of upper and lower pinch rollers 5 and 6 are provided with pinch roller motors 41 and 42, respectively, and are connected by rotation transmission timing belts 43 and 44, respectively.

  In the upper and lower press conveyors 3 and 4, the number of rotations of the pressing belts 11 and 12 is suppressed to the same conveying speed as that of the upstream conveying conveyor 7 (see FIG. 4). On the other hand, the pinch rollers 5 and 6 are set so that the rotational speed thereof is high and the bag-packing workpiece W is blown up to the product step portion 20. As the pinch rollers 5 and 6, for example, urethane rubber is used as the pinch rollers 5 and 6 having a holding force and high wear resistance so that the bag-packed workpiece W does not slip. Further, since the conveyance speed of the bagging workpiece W is rapidly increased by the pinch rollers 5 and 6, the upper press conveyor 3 is formed shorter than the lower press conveyor 4 on the discharge side (right side in the drawing). This is because when the conveyance speed of the bagging work W is switched at a high speed, the bagging work W is released from the sandwiching of the upper and lower press conveyors 3 and 4.

  A product stage 20 (see FIG. 4) is provided next to the product stage conveyor. In the stacking stage 20, as described above, the bag filling workpieces W are stacked five by five, and then pushed out to the packaging process side by the pusher 51. The pusher 51 is a plate for extruding the stacked bagging work W, and is configured to be integrated with the LM guide 52 and slidable in the horizontal direction of the drawing. A timing belt 55 is stretched between the servo motor 53 and the pulley 54, and the LM guide 52 reciprocates linearly by the rotation of the timing belt 55.

  In the workpiece stacking device 1, the rotation of the upper and lower press conveyors 3 and 4 is stopped at a predetermined timing, and the conveyance of the bagging workpiece W is temporarily stopped. This is to adjust the time while waiting for the push-out operation by the pusher 51. Therefore, a workpiece detection sensor (not shown) is provided near the exit of the upper and lower press conveyors 3 and 4 at a point S shown in FIG. The packaging device including the workpiece stacking device 1 is provided with a controller (not shown), and drive control of the press conveyor motors 31 and 32 is performed. A detection signal from the work detection sensor is sent to the controller, and the number of product stages of the packed work W is counted.

  Here, FIG. 6 is a view showing a lift mechanism for adjusting the height of the flight plate 23, and shows a state in which the workpiece stacking device 1 shown in FIG. 5 is viewed from the right side of the drawing. Sprockets 62 and 63 are attached to two upper and lower portions of the support column 61 that are fixed upright, and a chain 64 is stretched over the sprockets 62 and 63. The chain 64 is provided with four flight plates 23 at equal intervals, but is fixed so as to maintain a horizontal state when moving in the vertical direction. The upper sprocket 62 can be adjusted in the vertical direction. A pulley 66 is integrated with the lower sprocket 63, and a timing belt 68 is stretched between the servo motor 67.

  Therefore, in such a workpiece stacking device 1, the press conveyor motors 31 and 32 are driven, and the rotation is transmitted to the rotation transmission rollers 35 and 36 via the timing belts 33 and 34, respectively. Then, the press belts 11 and 12 are rotated by the rotation transmission rollers 35 and 36. The rotation speed of the press conveyor motors 31 and 32 is set lower than that of the upper and lower press conveyors 81 and 82 shown in FIG. 1, and the rotation of the pressing belts 11 and 12 is also the same speed as that of the immediately preceding transport conveyor.

  The pressing belts 11 and 12 are kept in a tensioned state without being loosened by the tension rollers 37 and 38, and the bagging workpiece W that has entered the upper and lower gaps is pressed from the upper and lower directions. The bagging work W that has entered the upper and lower press conveyors 3 and 4 is fed in the right direction of the drawing, but during that time, it is always compressed in the vertical direction. In this embodiment, since the rotational speeds of the pressing belts 11 and 12 are slow, the bagging work W is compressed over time, and strong folding is performed on the tissue paper that is the contents, and the bag is a package. The air inside is also pushed out sufficiently. Thus, the thickness of the bag filling workpiece W that has passed through the upper and lower press conveyors 3 and 4 is reduced.

  The rotation of the pinch roller motors 41 and 42 is transmitted via the timing belts 43 and 44, and the pinch rollers 5 and 6 are rotated at high speed. When the bag-filling work W exiting the upper and lower press conveyors 3 and 4 is released from the pinching, the leading end is drawn into the next pinch rollers 5 and 6, and the pinch rollers 5 and 6 rotating at a high speed at a stretch rightward. To the product stage. At this time, since there is a gap with the back bagging workpiece W, the passage of the bagging workpiece W is detected by the workpiece detection sensor, and the detection signal is transmitted to the controller.

  The bagging work W discharged by the pinch rollers 5 and 6 flies to the stacking step portion 20 and is placed on the flight plate 23. As the flight plate 23 is driven by the servo motor 67, the rotation output is transmitted from the timing belt 68 to the pulley 66 and the sprocket 63, and the chain 64 is rotated. The chain 64 shown in FIG. 6 rotates counterclockwise, and the bagging work W is placed on the flight plate 23 located on the lower left side of the drawing, which is the descending side.

  Since the loading stage of the bag-packed workpiece W can be confirmed by the detection signal of the workpiece detection sensor, the servo motor 67 is driven by the controller at a predetermined timing, and the flight plate 23 is moved by a predetermined distance every time one bag-packed workpiece W is loaded. Descend. In this way, the bagging work W from the pinch rollers 5 and 6 is received at substantially the same height, and stable stacking is performed. When five bagging workpieces W are stacked on the flight board 23, the flight board 23 is lowered to the height shown in the lower left side of FIG. 6 and stopped, and the rotation of the upper and lower press conveyors 3 and 4 is also temporarily stopped. Then, the pusher 51 is fed in the state of being stacked on the packing machine side.

  The pusher 51 performs the pushing operation to the right side of the drawing by the slide of the LM guide 52 via the timing belt 55 by the rotation of the servo motor 53, moves to the left side of the drawing by the reverse rotation, and returns to the state shown in the drawing. Thereafter, the next flight plate 23 stands by at the receiving position by the rotation of the chain 64, and the rotation of the upper and lower press conveyors 3 and 4 is restarted, whereby the bagging work W is compressed and stacked in the same manner.

  Therefore, according to the workpiece stacking device 1 of the present embodiment, since the compression time of the bagging workpiece W is lengthened by slowing the rotation of the pressing belts 11 and 12, the thickness of the bagging workpiece W is reduced to the set value. can do. For this reason, an error between the thickness of one bagging work W stacked on the flight board 23 and the descending distance of the flight board 23 is reduced, so that the uppermost bagging work W stacked on the product stage 20 is The position of the upper surface can be made almost constant regardless of the number of product stages. Thereby, the stacking mistake of the bagging workpiece | work W can be reduced significantly.

  Further, since the workpiece stacking device 1 does not change the posture of the bag-packed workpiece W in the process until it is stacked, the construction and maintenance costs of the device are simplified by simplifying the configuration of the workpiece stacking device 1. Will also be suppressed.

  Furthermore, the upper and lower press conveyors 3 and 4 are temporarily stopped in accordance with the push-out operation by the pusher 51. At this time, since the upper and lower press conveyors 3 and 4 are low speed, the bagging work W can be stopped at a predetermined position. . That is, it is easy to control the stop, and the pinch rollers 5 and 6 do not get caught. Therefore, after the restart, the pinch rollers 5 and 6 can firmly fly to the stacking portion 20, and the flight plate 23 Properly stacked on top of.

As mentioned above, although embodiment was described about the workpiece stacking apparatus which concerns on this invention, this invention is not limited to this, A various change is possible in the range which does not deviate from the meaning.
In the said embodiment, although the thing which used the tissue as the content was mentioned as the example as the bag-packing workpiece | work W, you may use a paper diaper etc. as the content in addition.
