In the apparatus of the present embodiment configured as described above, although not particularly illustrated, it is preferable that the pouch holder has a posture correcting member in addition to the pouch adsorbent. The posture correction member regulates contact with a specific side of the pouch that is in a free state when the suction force of the pouch adsorbent is temporarily released before holding the spout in a predetermined positional relationship, and holds the pouch again after the contact control. It is what you want to do.
[0033]
Next, the spout attachment procedure to the pouch in the apparatus of this embodiment will be described.
(1) First, the pouches 1 are alternately supplied from the two pouch supply devices 30 one by one to the pouch holders 24 of the rotary device 20. At this time, the rotating arm 29 shown in FIG. 5 is in the release position of the two-dot chain line, and the pouch 1 is held only by the adsorbing body 25 (25A and 25B) on the support column 28 side. Whether such a pouch is in a position and posture that can be sealed with a sensor is detected as appropriate, and unsuitable ones are collected without being sealed in a subsequent process, returned to the pouch supply device, and prepared for reuse.
{Circle around (2)} As the rotary device 20 rotates, the rotating arm 29 moves from the position of the pouch supply device 30 to the position of the spout supply device 40 until the rotating arm 29 is shown by a solid line in FIGS. 4 and 5. The other adsorbing body 26 opens the pouch 1 greatly by rotating the rotating arm 29 to the open position again while adsorbing the pouch with its adsorbing force.
(3) With the pouch opened, the pouch 1 is brought to the position of the spout supply device 40, and the spout 2 is inserted into the opening of the pouch.
(4) After that, the rotating arm 29 returns to the closed position again. The rotating arm 29 is provided with sandwiching members 27A2 and 27B2, and the spout is held via the pouch 1 by the paired sandwiching members 27A1 and 27B1 and the respective V-shaped groove portions.
(5) When the pouch 1 held by the pouch holder 24 and the clamping members 27A and 27B reaches the reciprocating revolving device 50 that is moving forward at the same speed as the rotary device 20, the pouch 1 is the first In the unit group 51, the flat edge of the opening is primary sealed (for example, heat sealed), the spout holding part is secondarily sealed (for example, heat sealed) in the second unit group 52, and the sealed part is cooled in the third unit group. Is done. That is, each of the pouches 1 held by the eight pouch holding bodies 24 is primarily sealed at a time by the first unit group 51, and the eight pouch holdings are performed while the reciprocating swivel device 50 moves backward and moves forward again. The body 24 reaches the position of the second unit group 52, where the pouch is secondarily sealed, and reaches the position of the third unit group 53 during the forward movement after the reciprocating swivel device 50 moves backward once again to cool the pouch. Is done. Thus, the opening of the pouch is sealed, and the spout is held by the pouch by the seal.
(6) The pouch with spout after cooling is taken out one by one by the take-out device 60 and carried out. The pouch with a spout is temporarily stored in a stacker or is conveyed to a filling device by a line, where the contents are filled.
(7) As a preferred embodiment, when the apparatus of the present embodiment is provided with a posture correcting member, the suction force of the pouch holder is once released before the spout is supplied, and the pouch is in a free state. The specific side is brought into contact with the posture correcting member and brought into a predetermined position and posture.
[0034]
【The invention's effect】
As described above, in the present invention, since the pouch and the spout are held by the holding device until they are sealed, the temporary sealing device is not required, and the device can be simplified. Furthermore, since the spout can be delivered without a temporary seal, the overall capacity of the spout attachment device can be increased. In addition, since the pouch in an inappropriate position / posture is not temporarily sealed, it is collected and reused, so that the material can be effectively used and the number of defective products is drastically reduced.
