Although not shown in the drawing, when the processing item “3 column extraction stack process” is selected, the 3 column extraction stack process may be performed.

  First, with reference to FIGS. 3, 4, 9 to 11, 14 to 16, etc., the operation of the molded product stacking device AP <b> 2 during the two-row extraction stacking process will be described. In this case, as illustrated in FIG. 4, dies 13 and 14 in which a plurality of molded products PR1 are formed in the arrangement direction D3 are attached to the tables 11 and 12. When the two-row stacking process is started, the molded product stacking device AP2 sets the lifting platform 20 to a height H1u higher than the height H1 of the height holding unit 30, and the stack jig 16 on the upstream side in the arrangement direction. The stack accommodating part 60 is arranged below (lower position L12), and the advance / retreat part 31 of the height holding part 30 is advanced to the ascending / descending path PA1 (advance position P31) of the first product stack ST1. When the punching unit 10 brings the dies 13 and 14 close to each other and punches the molded sheet SH12 to form the molded product PR1, the molded product PR1 descends into the stack jigs 15 and 16 from the mold holes C1 and C2, and the elevator 20 Product stacks ST1 and ST2 are stacked on top of each other. The molded product stacking device AP2 sets the lifting platform 20 every time the punching unit 10 punches the molded sheet SH12 by a set height corresponding to the height of one molded product PR1 constituting the product stacks ST1 and ST2. It may be lowered. During this time, the lifting platform 20 may be set to a height H1u that is equal to or higher than the height H1 of the height holding unit 30. Further, every time the punching unit 10 punches the molded sheet SH12, the knockout unit may push the molded product PR1 from the mold holes C1 and C2 to a predetermined height in the stack jigs 15 and 16.

  When a set number of molded products PR1 are stacked on the lifting platform 20 having a height H1u that is equal to or higher than the first height H1, the product stacks ST1 and ST2 stacked on each other are placed on the lifting platform 20 in the alignment direction D3. It becomes a state. In this state, as illustrated in FIG. 9, the molded product stacking device AP2 has an elevator platform up to a second height H2 at which the upper end ST2t of the second product stack ST2 is lower than the first height H1. 20 is lowered. At this time, the descending elevator 20 does not interfere with the height holding unit 30, and the second product stack ST2 descends with the elevator 20 placed on the elevator 20, and the elevator 20 reaches the second height H2. The first product stack ST1 is placed on the advancing / retreating portion 31 of the height holding portion 30.

  Next, as shown in FIG. 10, the molded product stacking device AP2 moves the stack accommodating portion 60 in the downstream direction D3a in the alignment direction D3, and the stack jig 16 on the downstream side in the alignment direction, that is, the height holding portion. The stack accommodating portion 60 is arranged at a lower position L11 of the first product stack ST1 held by the first product stack ST1. Further, the advancing / retreating portion 31 of the height holding portion 30 is moved from the ascending / descending path PA1 of the first product stack ST1 so that the first product stack ST1 is stacked on the second product stack ST2 in the planar position restricting portion 63 (stack accommodating portion 60).

Further, as shown in FIG. 11, the lifting platform 20 is lowered to a third height H3 where the upper end ST1t of the first product stack ST1 stacked on the second product stack ST2 is equal to or lower than the first height H1. . At this time, the stacked product stacks ST <b> 1 and ST <b> 2 are lowered while being placed on the lifting platform 20. Although it is preferable that the lift 20 is lowered from the second height H2 at the time when the height holding unit 30 is retracted or after it is retracted, the stability of the product stacks ST1 and ST2 is improved. The lowering of the lifting platform 20 from the second height H2 may be started simultaneously, or the height holding unit 30 may be retracted after the lifting platform 20 is lowered from the second height H2.

  As described above, the product stack ST0 is accommodated in the planar position restriction parts 631 to 636 shown in FIG. 8 and the like and is placed on the lifting parts 201 to 206. The product stack ST0 in this case is a stack of product stacks ST1 and ST2.

Move to. The return position L4 may be the same as the intermediate position L2 shown in FIG. 14, or may be a position different from the intermediate position L2. The planar position restricting unit 63 moving in the upstream direction D3b does not interfere with the sideways position holding unit 72, and the product stack ST0 in a sideways state is held on the sideways holding unit 72 and remains on the side table 74. Further, the stack accommodating portion 60 is tilted toward the placement position L1 and returned to the placement position L1. In addition, when the stack housing portion 60 starts to tilt toward the placement position L1 as the movement from the return position L4 to the placement position L1, the other portions such as the height holding portion 30 and the stack housing portion 60 do not interfere with each other. Can be. Of course, as long as it does not interfere with another part, the stack accommodating part 60 may start to tilt at the time of arrival at the placement position L1 or after arrival. Further, if the product stack ST0 in the laid-down state remains on the laid-down position L3, the stack housing unit 60 may start to tilt toward the placement position L1 before reaching the return position L4.

  As described above, the product stacking device of the present technology forms the product stack ST0 in which the first product stack ST1 is stacked on the second product stack ST2, thereby improving the efficiency of forming the product stack ST0. It becomes possible.

In this case, as illustrated in FIG. 5, dies 13 and 14 on which one molded product PR1 is formed in the alignment direction D3 are attached to the tables 11 and 12. When the stacking process for one row is started, the molded product stacking apparatus AP2 retracts the unnecessary advance / retreat portion 31 of the height holding portion 30 to the retreat position P32 and moves the lifting platform 20 to the height of the height holding portion 30. The stack accommodating portion 60 is arranged below the stack jig 15 at a height H1u higher than the height H1. When the punching unit 10 brings the molds 13 and 14 close to each other and punches the molded sheet SH12 to form the molded product PR1, the molded product PR1 descends into the stack jig 15 from the mold hole C1 and the product is placed on the lifting platform 20. Stack ST0 is stacked. The molded product stacking device AP2 lowers the lifting platform 20 every time the punching unit 10 punches the molded sheet SH12 by a set height corresponding to the height of one molded product PR1 constituting the product stack ST0. May be. Further, every time the punching unit 10 punches the molded sheet SH12, the knockout unit may push the molded product PR1 from the mold hole C1 to a predetermined height in the stack jig 15.

  When the molded product PR1 is stacked on the lifting platform 20 having a height H1u that is equal to or higher than the first height H1 by the set number, the molded product stacking device AP2 is configured such that the upper end of the product stack ST0 is lower than the first height H1. The lifting platform 20 is lowered to a third height H3 (see FIG. 11). At this time, the product stack ST0 is lowered while being placed on the lifting platform 20, and when the lifting platform 20 reaches the third height H3, the product stack ST0 is moved to the planar position restriction portion 63 of the stack accommodating portion 60. It is in a housed state. Thereafter, as shown in FIGS. 14 and 15, the molded product stacking device AP2 moves the stack housing portion 60 from the placement position L1 to the midway position L2 without tilting, and tilts the stack housing portion 60 to stack each product stack.

With the advancing / retreating portion 73 of the sideways position holding unit 72 advanced to the return path PA2, the molded product stacking device AP2 is arranged in the alignment direction D3 from the sideways position L3 to the return position L4 without tilting the stack housing portion 60. In the upstream direction D3b. Further, the stack accommodating portion 60 is tilted toward the placement position L1 and returned to the placement position L1.

  As described above, the product stacking device of the present technology stacks the first product stack ST1 and the second product stack ST2 and conveys them to the take-out position, and takes the product stack ST0 to the take-out position without such stacking. It can be switched according to the shape of the product. Therefore, the product stacking device of the present technology is convenient.

The stack accommodating portion 60 described above is included in the molded product stack packaging device AP1. The operation of the molded product stack packaging apparatus AP1 will be described below with reference to FIGS.
When the product stack ST0 in the laid-down state is placed on the horizontal placement table 74 at the laid-down position L3, the transfer unit 70 moves the advancement unit 73 (the laid-down position holding unit 72) to the advancement position P71, and the product in the laid-down state The horizontal stand 74 on which the stack ST0 is placed is laid down and moved from the position L3 to the pushing position L5. In the transfer unit 70 illustrated in FIG. 6, first, since the horizontal placement unit 741 arrives at the pushing position L5, the advance / retreat unit 73 of the corresponding sideways position holding unit 721 is retracted to the retreat position P72. Then, the stack pushing part 80 pushes out the product stack ST0 on the horizontal placing part 741 in the pushing direction D4a. Next, the transfer unit 70 slightly moves the horizontal mounting table 74 in the downstream direction D2a in the axial direction D2, and retracts the lateral position holding unit 722 corresponding to the horizontal mounting unit 742 that has arrived at the pushing position L5. Then, the stack pushing unit 80 pushes out the product stack ST0 on the horizontal placing unit 742 in the pushing direction D4a. Thereafter, the product stack ST0 on the horizontal placement parts 743 to 746 is extruded in the same manner in the extrusion direction D4a. Each extruded product stack ST0 enters the film F1 and is packaged as shown in FIG. In this way, the packaging unit 90 packages the product stack ST0 extruded by the stack extrusion unit 80 to form a product stack packaged product PR2.

  Each product stack ST <b> 0 in the sideways state disposed at the sideways position L <b> 3 is in a different position in the axial direction D <b> 2 along the tilt axis AX <b> 1. These product stacks ST0 move in the axial direction D2 up to the pressing position L5, and are extruded and packaged in the extrusion direction D4a different from the axial direction D2. Therefore, the product stack packaging apparatus of the present technology can improve the efficiency of forming the product stack packaged product PR2.
