Accordingly, the roller 24 is rotated by friction, and the plastic bag 1 is guided by the roller 24. The shutter bar 5 does not engage with the plastic bag 1, and the plastic bag 1 is not damaged by the shutter bar 5.
- each shutter bar 5 is lowered to the original position (FIG. 12C). Accordingly, the plastic bags 1 are stacked on the conveyor 4, and the conveyor 4 has a plurality of belts. Further, the width of the shutter bar 5 is partially reduced at the lower end (FIG. 15B). When each shutter bar 5 is lowered, the reduced portion is inserted into the slot 22, and the roller 24 is also inserted into the slot 22. Therefore, the plastic bag 1 is blocked by the shutter bar 5.
- each pressing bar 18 and the receiving member 19 are fixed by the spacer 27, and an auxiliary body 20 is provided on each pressing bar 18. Then, at the position beyond the tip of the pressing bar 18, the receiving member 19 is bent or bent downward (FIG. 16A). Therefore, when the pressing bar 18 and the receiving member 19 are lowered, each receiving member 19 is first engaged with the conveying conveyor 4 and pressed, and then the receiving member 19 is elastically deformed, and each pressing bar 18 is plastic bag 1. The plastic bag 1 is pressed by the pressing bar 18 (FIG. 16B). Thereafter, each receiving member 19 receives a subsequent bag. Therefore, when the plastic bag 1 is conveyed, the rear bag is blocked by the receiving member 19.
- the pressing bar 18 passes over the tip of the receiving member 19, and at that position, the pressing bar 18 is bent or bent upward (FIG. 16C).
- the back bag may be blocked by the curved or bent portion 28.
- each receiving member 19 may be provided with a curved portion so that the subsequent bag engages with the curved portion and faces upward so that it is difficult to slip between the shutter bar 5 and the conveyor 4.
- the sheet-like products can be stacked and transported by this device.
