Further, the stacking and transporting machine 1 has a transporting path 10 that slides and transports the stacking body. The bucket conveyor moves the bucket 301 so as to be positioned below the transport path 10 (see FIG. 1A).

  The finger conveyor 200 arranged upstream conveys the PTP sheet at a predetermined interval at a constant speed, and sends it to the stacking and conveying machine 1. The PTP sheets 100 conveyed to the finger conveyor 200 are conveyed one by one with the convex portions for storing the tablets alternately directed upward or downward and with the long sides directed downstream. Further, guides (not shown) are provided at both edges of the finger conveyor 200 so that the PTP sheet does not shift laterally.

  The packaging machine is a known boxing and conveying machine. The packaging machine has a bucket conveyor 300 disposed below the conveyance path 10. A plurality of buckets 301 are provided on the bucket conveyor 300 with a predetermined interval, and a box body 302 having an open top is placed on each bucket. The bucket conveyor 300 moves the bucket 301 in the horizontal direction at a constant speed along the transport path 10, and the stacked body 101 dropped from the stacking and transporting machine 1 is accommodated in the box body 302 and packaged. The

  The stacking and transporting machine 1 is a transporting machine that transports articles by linear driving, and includes a plurality of movers 20 that transport a stack, a planar stacking means 30, and an annular stator that forms a moving path of the mover. 40 and the conveying path 10 that slides and conveys the accumulation body (see FIG. 1A).

  Below each mover 20, a front support piece 21 that supports the front of the integrated body 101 and a rear support piece 22 that supports the rear are branched and provided at the front and rear of the mover 20. Each of the front support piece 21 and the rear support piece 22 is a wide plate-like body in a direction crossing the transport direction (see FIG. 1B). Moreover, the lower end part of each plate-like body is provided with a convex part 23 that fits in a guide groove 11 (see FIG. 2A) that extends along the conveyance direction formed on the top surface of the conveyance path 10. Yes. At the time of conveyance, the front support piece 21 and the rear support piece 22 are guided with the convex portion 23 fitted in the guide groove, so that the PTP sheet 100 is reliably conveyed without being removed from the conveyance path.

  In a state where the mover 20 is accelerated, the stack 101 is supported by the rear support piece 22, and in a state where the mover is decelerated, the stack 101 is supported by the front support piece 21. It is made not to be biased. Further, when the integrated body is dropped and delivered, the front side of the integrated body 101 is supported by the front support piece 21, so that the integrated body is in a state where the front end portions of the planar bodies forming the integrated body are aligned. 101 can be dropped into the lower bucket 301 so as not to collapse.

  The stacking unit 30 includes a receiving unit 31 and a holding unit 32. The receiving means 31 is disposed at the starting end of the conveyance path 10 and pushes up and receives the PTP sheet 100 one by one between the front support piece 21 and the rear support piece 22 in a stopped state (FIG. 1A). FIG. 3 (see FIG. 3A). The receiving means 31 includes a push-up plate 310 that pushes up the planar body 100, a lifting shaft 311 that raises and lowers the push-up board, a driving means (not shown), and a position in front of the planar body that is transported from upstream to the beginning of the transport path. And a hanging wall 312 that stops so as to be aligned (see FIG. 1).

  Each time the planar body 100 is conveyed one by one from the upstream, the elevating shaft 311 is moved up and down once. As the elevating shaft is raised, the planar body 100 is pushed up by the push-up plate 310 and is received between the front support piece 21 and the rear support piece 22 (see FIGS. 1A and 1B). ). Similarly to the transport path, the top surface of the push-up plate 310 is also provided with a streak-shaped guide groove 313 that guides the convex portion 23 provided at the lower end of the front support piece and the rear support piece in the transport direction. In the stacking position where the PTP sheet 100 is received between the front support piece 21 and the rear support piece 22, the lower holding piece 320 that supports the pushed-up planar body forming the holding means 32 so as not to fall, and the planar body An upper holding piece 321 in contact with the upper surface is formed.

  The lower holding piece 320 is expanded to the left and right by the ascent of the PTP sheet 100 and allows the planar body 100 to pass through (see FIG. 2B). The upper holding piece 321 is pushed up by the planar body 100 and rises. The upper holding piece 321 is suspended downward by the elastic means 322 so that the left and right ends of the PTP sheet 100 are pressed with a small force so as not to float. After each planar body 100 is set to a predetermined height, the lower holding piece formed as an outwardly curved claw 323 returns to the original position, and the side end portion of the lower surface of the lowermost planar body 100 is It supports so that a planar body may not fall (refer FIG.2 (C) figure).

  The lower holding piece 320 is provided with a shaft moving portion 324 for axially moving outward at the lower end, and the lower holding piece is held downward while the outer side of the lower holding piece is urged by the urging means 325 and the push-up plate 310 is lowered. The one claw 323 is returned inward and returned to the original position, and the claw 323 supports the planar body 100 (see FIG. 2C and FIG. 2E). The distance of the state in which the left and right claws 323 are returned inward is wider than the width of the push-up plate 310 and shorter than the length of the long side of the PTP sheet 100 (see FIG. 1B). The upper holding pieces 321 push down both side ends of the planar body with a small force so that the planar body does not float at the accumulation position.

  At the stacking position, the lower holding piece 320 and the upper holding piece 321 serve as the holding means 32. On the other hand, when the stack 101 is moved from the stack position to the end of the conveyance path, the stack 101 is separated from the upper holding piece 321 and the lower holding piece claw 323 supporting the planar body. In the first embodiment, the position control for moving the mover from the stacking position serves as a holding release unit. In a state where the accumulation body is slid along the conveyance path 10, the conveyance path itself supports and holds the lower surface of the accumulation body.

  In the flat body receiving process, the first PTP sheet 100 with the convex portion directed downward is stopped in a state where the first PTP sheet 100 is in contact with the hanging wall 312 and is positioned on the push-up plate 310 ( (See FIG. 1A and FIG. 2A). When the elevating shaft 311 is raised, the push-up plate 310 pushes up the PTP sheet 100, and the bottom surface (the upper surface in the drawing) of the PTP sheet reaches the height of the claw 323 of the lower holding piece, the urging means 325 Against the urging force, the lower holding piece 320 is axially moved outward, and the distance between the left and right claws 323 is widened (see FIG. 2B).

  Further, the elevating shaft 311 is raised, the PTP sheet is raised higher than the claws 323, both side ends of the flat portion of the PTP sheet 100 are in contact with the lower surface of the upper holding piece 321 provided on both side ends of the accumulation position, and PTP The sheet 100 and the upper holding piece 321 are pushed up together. Here, the claw 323 is returned to the original position by the urging force of the urging means 325 (see FIG. 2C). When the elevating shaft 311 is lowered, the push-up plate 310 is lowered and the upper holding piece 321 and the PTP sheet 100 are lowered.

  Since the length in the long side direction of the PTP sheet 100 is longer than the distance between the left and right claws 323, both ends of the flat portion of the PTP sheet are caught by the left and right claws 323 (see FIG. 2C). ). The upper holding piece 321 stops descending as the PTP sheet 100 descends. As a result, the PTP sheet 100 is held in a state of being sandwiched between the lower holding piece 320 and the upper holding piece 321.

  Next, the second PTP sheet 102 with the convex portion directed upward is positioned on the push-up plate (see FIG. 2D). As with the first PTP sheet, the elevating shaft is raised, and the lower holding piece is axially moved outward by pushing up the claws at both ends of the PTP sheet. And the raising / lowering axis is further raised.

  Then, the first PTP sheet 100 that has been held first is pushed up by the second PTP sheet 102 and stacked so that the convex portions of the two PTP sheets 100 and 102 are held together (see FIG. (See Fig. 2 (E)). Then, the stacked PTP sheets are caught by the claws 323, and after the stacked PTP sheets are held between the lower holding piece 320 and the upper holding piece 321, the lifting shaft 311 is lowered.

  The above steps are repeated until a predetermined number of planar bodies are stacked to form the integrated body 101. In the state in which the last planar body is received, the elevating shaft 311 is raised until the height of the push-up plate 310 coincides with the height of the top surface of the conveyance path 10 (FIG. 2 (F), (See FIG. 3A). In this state, the mover is moved toward the downstream side, and the stacked body 101 is pushed out so as to slide into the transport path 10 and the transport process is started (see FIG. 3A).

  The lifting shaft 311 maintains the state in which the height of the push-up plate 310 coincides with the height of the top surface 10 of the conveyance path until the entire bottom surface of the stacked body 101 reaches the conveyance path (see FIG. 3B). ). Then, after the entire aggregate has moved to the conveyance path, the conveyance path 10 holds the accumulation body, and the lifting shaft 311 is lowered (see FIG. 3C). Then, the next mover is moved to the accumulation position, and the flat body receiving process is resumed.

  Here, the conveyance path 10 will be described with reference to FIG. The conveyance path 10 extends in one direction, has a hanging wall 312 that forms the receiving means 31 at the start end, and is provided with a sliding slope 12 that slides down the stack before the position at which the stack is dropped. Further, the top surface of the transport path 10 is provided with a streak-shaped guide groove 11 formed over the entire length of the transport path, and the guide groove 11 has a convex provided on the front support piece 21 and the rear support piece 22. Part 23 is guided.

  The sliding slope 12 is a curved surface that is smoothly curved upward and convex. At the position of the sliding slope 12, the integrated body 101 is in a state where the front is slightly inclined downward along the curved surface. Then, the bottom surface of the aggregate 101 and the conveyance path 10 are in contact with each other at a linear portion that crosses the curved surface, the contact area is reduced, and the frictional resistance is reduced. As a result, the lowermost planar member is not left in the conveying path 10 due to frictional resistance, and even if it is an unbound flat member stack 101, the entire stack of the lower bucket 301 can be smoothly smoothed. Can slide down inside.

  Since the convex portion 23 of the front support piece 21 supports the front of the lowermost planar body, only the lowermost planar body does not slide down first. Then, in a state where the entire aggregate has reached the end of the sliding slope 12, the entire aggregate is dropped and accommodated in the lower bucket 301 (see FIG. 1A).

  Further, the transport path 10 includes a defective product detection unit 130 and a defective product discharge unit 13 upstream of the sliding slope 12. The defective product discharging means 13 includes an opening / closing means 131 and a defective product dropping hole 132 of the transport path 10. The defective product detection means 130 is a well-known optical sensor disposed on the side of the transport path 10 and detects the number of stacked planar bodies constituting the transported integrated body. If the number of stacks detected by the defective product detection means is a predetermined number, the defective product drop holes 132 are not opened by the opening / closing means 131, and the stacked body 101 is located at the position of the defective product drop holes in the transport path 10. Passed through.

  On the other hand, when the number of stacks detected by the defective product detection means is different from the predetermined number, the opening / closing means 131 causes the conveyance path at the position of the defective product drop hole to move downward to cause a failure. The non-defective product dropping hole 132 is opened. When the defective product 110 reaches the defective product dropping hole 132, the defective product is dropped and removed from the conveyance path 10 (see FIG. 1A). Since the defective product 110 is discharged in advance from the defective product dropping hole 132 arranged upstream from the discharge position, only the non-defective product that conforms to the predetermined number is discharged without the defective product 110 reaching the bucket 301.

  The stator 40 that forms the moving path of the mover 20 includes an electromagnet 41 that generates electromagnetic interaction, a mover position detecting unit that detects the current position of each mover, and a control unit for the mover. Yes. The electromagnet is provided in an annular shape along the movement path. The mover position detecting means is an encoder 42 provided in a ring shape along the movement path, and detects the position information of the mover by reading the wireless communication tag 24 provided on the mover. The wireless communication tag 24 may be any wireless communication that uses an electromagnetic field or a radio wave, and is not limited. For example, a well-known RFID can be suitably used.

  The control means for the mover 20 includes a mover position control means for controlling the position of the mover and a mover speed control means for controlling the speed of the mover. The mover position control means may control the position of the mover so as to match the stacking position, the position where the mover is accelerated / decelerated, and the position where the stack is dropped on the bucket constituting the packaging machine.

  The mover speed control means accelerates or decelerates the mover so as to reach a predetermined position specified by the mover position control means, and moves each mover so as not to collide with the previous mover. Is controlled. Specifically, until the mover 20 reaches the sliding slope 12 (section α in FIG. 1A), the movable body 20 is moved at a higher speed in order to increase the conveyance efficiency of the stacked body 101. After the mover 20 reaches the sliding slope 12 of the conveyance path (FIG. 1A, section β), the mover 20 is controlled to smoothly decelerate so that the integrated body does not collapse with rapid deceleration. . In addition, when the accumulation body is difficult to collapse, it is not necessary to provide a section for smoothly decelerating the mover.

  When the mover 20 reaches the end of the conveyance path 10 (section γ in FIG. 1A), the moving speed of the mover is controlled so as to be synchronized with the moving speed of the bucket 301. Since the mover moves at a speed synchronized with the moving speed of the bucket 301 and slides the stack 101, it is conveyed to the bucket 301 that is moved at a synchronized speed without stopping the packaging machine. The accumulation body 101 is accommodated in the box 302.

  In the second embodiment, a stacking and conveying machine 2 in which front and rear support pieces 52 and 53 are separately provided on movable elements 50 and 51 adjacent to each other in the front and rear directions will be described with reference to FIG. 4A is a side view of the stacking and conveying machine 2 from the side of the conveying path 10, and FIG. 4B is an explanatory diagram of a cross-section at the position AA in FIG. Is shown. Compared with the stacking and transporting apparatus of the first embodiment, the stacking and transporting machine 2 slides down on the transporting path 14 in that the front support piece and the back support piece are individually provided in the front and rear movable elements 50 and 51. The difference is that the slope and the defective product discharging means are not provided, and the other configurations are the same. About the same structure, the code | symbol same as Example 1 is attached | subjected and description is abbreviate | omitted.

  A front support piece 52 that supports the front of the stack 101 is provided below the front mover 50, and a rear support piece 53 that supports the back of the stack is provided below the rear mover 51. . Both the front support piece 52 and the rear support piece 53 are arranged at the center in the front-rear direction of the mover, and are formed into a wide plate-like body in a direction intersecting the transport direction (see FIG. 4B). Moreover, the lower end part of each plate-like body is provided with a convex part 23 that fits in the guide groove 11 that is formed on the top surface of the transport path 14 and extends along the transport direction.

  Adjacent movers 50 and 51 are stopped side by side in the transport direction across the stacking means 30, and are placed on standby to allow the PTP sheet 100 to be received between the front support piece 52 and the rear support piece 53. The In this waiting state, the receiving means 31 forming the stacking means 30 is placed between the front support piece 52 and the rear support piece 53 in the same manner as the stacking process shown in the first embodiment. The planar body received by the holding means 32 (see FIG. 9B) is held so that it does not fall to form the integrated body 101. In the second embodiment, the position control that moves the two movable elements sandwiching the front and rear of the stack from the stacking position in synchronization forms the holding release means.

  Since the front support piece 52 and the rear support piece 53 are individually provided in the movable elements 50 and 51 adjacent to each other in the front-rear direction, the position of the front support piece 52 and the front support piece 52 are controlled so as to change the position where each movable element is stopped. If the distance from the rear support piece 53 is changed, it can be easily applied even when the length of the planar body in the front-rear direction is different.

  In the state where the two movers 50 and 51 are waiting to receive the planar body, the distance between the front support piece 52 and the rear support piece 53 is slightly longer than the length of the PTP sheet 100 in the front-rear direction. If the position of the mover is controlled so that the flat body is not easily damaged during reception. During conveyance, if the position of the mover is controlled so that the distance between the front support piece 52 and the rear support piece 53 is adapted to the length in the front-rear direction of the planar body 100, the mover is accelerated rapidly. -A planar body does not shift | deviate also by deceleration, and it is suppressed that a needle | mover collides with either the front support piece 52 or the back support piece 53. FIG.

  After the two movers 50 and 51 start conveying the stack 101, the distance between the front support piece 52 and the rear support piece 53 is set to be the same as the distance that supports the front and rear of the stack 101. Then, the sheet is conveyed downstream (FIG. 4A, section α in FIG. 4). When reaching the section to be decelerated, the two movers are gradually decelerated simultaneously so that the two movers 50 and 51 are synchronized with the moving speed of the bucket 301 in a short time (FIG. 4A). (Figure β section). Then, when reaching the end of the conveyance path 14, the two movers 50 and 51 are synchronized with the moving speed of the bucket 301 and drop the integrated body 101 onto the lower packaging machine (section γ in FIG. 4A). .

  Since the front of the stack is supported by the front support piece 52, when the stack 101 is dropped from the terminal end of the transport path 14, the front position of each planar body forming the stack may be shifted. Absent. Therefore, even if it is an unbound stack, it is dropped into the lower bucket 301 in a state where all of the planar bodies are aligned.

  In the third embodiment, the front and rear support pieces 54 and 55 are individually provided on the movers 50 and 51 adjacent to each other in the front-rear direction, and the front support piece 54 is provided rearward in the transport direction. The stacking and conveying machine 3 in which 55 is provided in the forward direction in the conveying direction will be described with reference to FIG. The stacking means and the holding release means are the same as those in the second embodiment. FIG. 5A shows a case where a narrow planar member is conveyed, and FIG. 5B shows a wide plane by changing the roles of the front and rear movers. The case where a state-like object is conveyed is shown. Each drawing in FIG. 5 shows a side view of the stacking and conveying machine 3 from the side of the conveying path.

  The mover forming the linear transport machine needs to have a predetermined length in the front-rear direction in order to store the electromagnet 41 (see FIG. 1B), and is moved apart so as not to contact each other. So that it is controlled. Therefore, when a front support piece and a rear support piece are provided at the center of the mover, a movable body in which a planar body shorter than the distance in the front-rear direction of the movers 50 and 51 (FIG. 5A) is arranged in the front-rear direction. Cannot be transported with a child. The stacking / conveying machine 3 is a stack 104 in which the front support piece 54 is disposed rearward and the rear support piece 55 is biased forward, and the PTP sheets 103 having a narrower width (FIG. 5A and FIG. Β) are stacked. Even if there is, it can be transported.

  Specifically, when the PTP sheet 103 having a narrow width is conveyed (see FIG. 5A), a front support piece 54 biased rearward is disposed in front of the stack 104, and the stack On the rear side, a rear support piece 55 biased forward is disposed, and is set to the accumulation position. Even if the PTP sheet 103 has a length in the front-rear direction that is shorter than the interval between the center positions of the movers, the receiving length at the stacking position is shortened. It can be conveyed while being supported by the piece 55.

  On the other hand, when a wide PTP sheet 105 is conveyed (see FIG. 5B), the position is controlled so that the roles of the front and rear movers are changed. Then, the mover 51 having the rear support piece 55 attached to the front side of the integrated body 106 on which the PTP sheets 105 are integrated is stopped, and the rear side of the integrated body is attached to the rear side. The movable member 50 having the front support piece 54 is stopped, and the front-rear interval of the accumulation position formed by the rear support piece 55 to be positioned forward and the front support piece 54 to be positioned rearward is increased. . Then, a planar body longer in the front-rear direction than the distance in the front-rear direction of the movers 50, 51 (FIG. 5B, FIG. Α) can be transported (FIG. 5B, FIG. 5). .

  In the fourth embodiment, a stacking and transporting machine 4 that transports the stack in a floating state will be described with reference to FIGS. 6 and 7. FIG. 6A shows a side view of the stacking and conveying machine 4 from the side of the conveying path. FIG. 6 (B) shows a state of being accumulated by the accumulation means. FIG. 7A shows a state of being transferred between the front support piece and the rear support piece from the accumulation position, and FIG. 7B shows a state of being moved forward from the accumulation position. Yes. FIG. 7C shows a state of dropping into the bucket.

  Compared with the stacking and transporting machine of the second embodiment, the stacking and transporting machine 4 hooks the bottom surface of the stacking body at the lower ends of the front support piece 61 and the front of the back support piece 62 provided in the mover 60. The holding claw with a small thickness is held and the convex part is not formed at the lower end, the position control at the stacking position and the discharge position is different, and there is no conveyance path, so the stack is at a height closer to the bucket. The point of being dropped is different.

  A front holding claw 63 having a small thickness extending rearward in the transport direction is provided at the lower end portion of the front support piece 61. A rear holding claw 64 having a small thickness extending forward in the transport direction is provided at the lower end of the rear support piece 62, and is held so that the stacked body being transported does not fall. The PTP sheet 100 conveyed by the upstream finger conveyor 200 abuts on an upright wall 314 formed in front of the stacking unit 30 and is received by the receiving unit 31 that forms the stacking unit as in the second embodiment, and is held by the holding unit 32. The accumulated body 101 accumulated by the claws 323 (see FIG. 2) is held at the accumulation position 70 (see FIG. 6B).

  The front support piece 61 stands by slightly in front of the stacking position 70 so that the front holding claws 63 do not interfere with the stacking of the planar bodies. The rear support piece 62 stands by slightly behind the accumulation position with the accumulation position 70 in between. When the PTP sheet 100 is used as the accumulation body 101, the push-up plate 310 is lowered, and the lower ends of the both end portions of the accumulation body are held on the claws 323 (see FIG. 2) forming the lower holding piece 320. Is done. The height of the top of the front holding claw 63 and the rear holding claw 64 is the same as the height of the top of the claw forming the lower holding piece 320 (see FIG. 6B). It is preferable that the front holding claw and the rear holding claw have smooth surfaces with little frictional resistance.

  In a state where the accumulation body 101 is held by the claw forming the lower holding piece 320, the movable element having the rear support piece 62 moves forward, and the accumulation body is placed on the rear holding claw 64 and pushed forward. The stacked body 101 is placed on the front holding claw 63 and the stacked body 101 is supported by the front holding piece 61 and the rear support piece 62 (see FIG. 7A), and the two adjacent movable elements 60 are used. , 60 are moved synchronously. While the two movers 60 are moving, the front holding claw 63 and the rear holding claw 64 hold the integrated body 101 so as not to fall (see FIG. 7B).

  The rear support piece 62 is stopped at a position slightly in front of the stacked body 101 reaching the upper part of the bucket 301. The front support piece 61 is moved to a position just above the bucket 301. If it does so, the space | interval of the front-end | tip of the front support claw 63 and the front-end | tip of the back support claw 64 will become longer than the length of the front-back direction of the PTP sheet 100. When the rear support piece 62 stops, the integrated body advances forward by inertial force from the rear holding claw 64 with low frictional resistance. Since the front holding claw 63 has moved further forward than directly above the bucket 301, the integrated body 101 is also released from the holding of the front holding claw 63 and dropped downward.

  Since the opening of the bucket 301 is located close to the lower ends of the front holding claw 63 and the rear holding claw 64, even if the stack 101 is tilted in any direction, it is greatly displaced. Therefore, the PTP sheets 100 are dropped in a state where the PTP sheets 100 are aligned with the bucket 301, and the planar body does not fall out of the bucket 301 (see FIG. 7C). In the fourth embodiment, the position release control is performed by stopping the mover provided with the rear support piece 62 and preceding the mover provided with the front support piece 61.
