A gripping unit 61, a gripping unit lifting mechanism 62 that lifts and lowers the gripping unit 61 between the spout supply position β and the spout insertion position γ, and a pair of suction heads 63 that open the opening edge of the pouch P at the spout insertion position γ. 63, and a pair of seal heads 64 and 64 for temporarily fixing the spout S inserted into the pouch P to the pouch P, as shown in FIG. 2, the spout S supplied to the spout supply position β The gripping unit 61 that grips the mouth is lowered by the gripping unit lifting mechanism 62, so that a pair of suction heads 63 and 63 are attached to each other as shown in FIG. Therefore, the spout S is inserted into the pouch P from the upper end opening of the opened pouch P.

  As shown in FIG. 14, the gripping unit 61 is attached to a chuck cylinder 611 having a pair of chucks 611a and 611a to be opened and closed, and chucks 611a and 611a of the chuck cylinder 611 via attachment members 612 and 613, respectively. Grasping claws 614 and 615 are provided, and the gripping claws 614 and 615 have engaging portions 614a and 615a that engage with the neck portion of the spout S as shown in FIG.

  One gripping claw 614 is fixedly installed on the mounting member 612, while the other gripping claw 615 is rotatably supported by the mounting member 613 so as to open and close with respect to the one gripping claw 614. The gripping claws 615 are always urged in the closing direction by the urging force of the spring 616.

  Accordingly, when the pusher 333a of the second spout transfer mechanism 333 constituting the spout transfer unit 33 of the spout supply unit 3 pushes out the spout S toward the spout supply position β along the guide groove 331c, FIG. As shown in FIG. 13, the spout S pushed out is engaged with the engaging portions 614a and 614b of both gripping claws 614 and 615 as shown in FIG. The gripping claws 614 and 615 are gripped.

  As shown in FIG. 3, the pair of seal heads 64 and 64 are formed in a substantially U-shape that surrounds the pair of suction heads 63 and 63, respectively, and the pair of seal heads 64 and 64 opens the pouch P. By gripping the outside of the spout S at the edge, as shown in FIG. 15, a spot seal part PS is formed in which the opening edges of the pouch P are heat-sealed in the vicinity of both side edges of the mounting part IP of the spout S. The spout S inserted into the pouch P is temporarily fixed to the pouch P.

  As shown in FIG. 3, the spout mounting part 7 mounts the spout S on the pouch P by sandwiching the opening edge of the pouch P to which the spout S is temporarily fixed at the first seal position ε and heat-sealing. A first seal unit 71 having a pair of seal bars, and a second seal unit 72 having a pair of seal bars that completely heat seal by sandwiching the upper edge of the pouch P to which the spout S is attached at the second seal position ζ. And a cooling unit 73 having a pair of cooling bars that sandwich and cool the upper end opening of the closed pouch P at the cooling position η, and the pouch next to the cooling position η from the first seal position ε. In order to prevent the pouch P to which the spout S is attached from being bent until the stop position, the pouch P is placed on both sides of the transport path of the pouch P. A pair of guide plates 74 and 74 for guiding the protruding portion from the pouch P are installed.

  As described above, in this spout mounting device 1, the pouch supply unit 2 uses the pouch P supplied by the pouch supply conveyor 21 to the pouch accumulation position ω between the pouch supply conveyor 21 and the pouch delivery unit 23. Since the pouch stocker 22 is provided so as to be stacked up and down in the lowered state, the pouch at the lowest position accumulated in the pouch stocker 22 is sequentially sent to the pouch delivery unit 23 one by one. When the pouch P is replenished to the conventional pouch P, the pouch delivery unit receives the uppermost pouch transferred by the pouch supply conveyor by sucking and holding it with a suction member (FIG. 18). As shown in Fig. 2), it is already placed on the pouch supply conveyor when the pouch is replenished. It is not necessary to replenish a new pouch so as to be inserted under the pouch, and a new pouch P should be placed on the pouch P already placed on the pouch supply conveyor 21 at random. Therefore, the replenishment work of the pouch P can be performed easily.

  Further, the pouch supply conveyor 21 is provided with restriction guides 213a, 213b, and 213c for restricting the movement of the upper pouch P toward the pouch stocker 22 to the guide plate 212, so that a large number of pouches are stacked at a time. Since P is not supplied from the pouch supply conveyor 21 to the pouch stocker 22, an appropriate amount of the pouch P is always accumulated in the pouch stocker 22, and the pouch stocker 22 is located at the lowest position where the pouch stocker 22 is accumulated. The pouches P can be reliably sent to the pouch delivery unit 23 one by one.

  Further, in the pouch supply part 2, the unsealed upper end opening UE faces the upstream side in the supply direction of the pouch P, in other words, the sealed bottom gusset part is downstream in the supply direction of the pouch P. Since the pouch P is transferred in a state of facing the pouch P, when the pouch P is sent from the pouch stocker 22 to the pouch delivery unit 23, the unsealed upper end opening UE is not caught by the regulating member 223. The pouch P can be smoothly and reliably sent to the pouch delivery unit 23 one by one.

  In particular, the bottom gusset-type pouch P has a state in which the upper end opening UE is overlapped with two sheets, whereas the bottom gusset part is in a state of overlap of four sheets. When the bottom gusset type pouch P is transported in a state where the gusset portion is thick and the thin upper end opening UE faces the downstream side in the supply direction of the pouch P, the pouch is supplied in a state where a large number of pouches P are stacked. When the conveyor 21 is replenished, the placement state of the pouch P is not stable, and the pouch P cannot be smoothly and reliably supplied to the pouch stocker 22. Therefore, when the pouch P is a bottom gusset type, as described above, it is desirable to transfer the pouch P in a state where the thin upper end opening UE faces the upstream side in the supply direction of the pouch P.

  In the above-described embodiment, the case where the spout S is mounted on the bottom gusset type pouch P has been described. However, the spout mounting device of the present invention is not limited to the bottom gusset type pouch, and the side gusset type. Needless to say, the present invention can also be applied to a case where a spout is attached to a pouch without a gusset portion.
