Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging apparatus provided with a bag take-out section for taking out a large number of accommodating bags stacked in a bag accommodating section one by one from the uppermost one in order.

[0002]

2. Description of the Related Art Conventionally, as the above-mentioned packaging device, a first suction nozzle that suctions near the opening of the uppermost storage bag, and the first suction nozzle near the opening of the uppermost storage bag. And a first suction nozzle moving mechanism that separates the uppermost storage bag by separating the first suction nozzle that has suctioned to the storage bag from the bag storage portion. There was one provided in the take-out part.

[0003]

The storage bag is generally made by stacking two thin films (for example, one made of polyethylene or polypropylene) and sealing the side portions and the bottom portions. In the state in which a large number of sheets are stacked in the bag storage portion, the vicinity of the opening portions of the adjacent storage bags are in close contact with each other due to static electricity or the like.

For this reason, in the conventional means, the first suction nozzle is sucked into the vicinity of the opening of the uppermost storage bag so as to be separated from the bag storage portion. It may be difficult to accurately separate only the uppermost storage bag because one or several sheets are attached to the uppermost storage bag.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a packaging device capable of improving the workability by accurately separating only one uppermost storage bag from the lower storage bag.

[0006]

The characteristic constitution of the present invention is that the first and second adsorption members can be adsorbed and desorbed in the vicinity of the bottom portion of the uppermost bag.
A suction nozzle and a first suction nozzle moving mechanism for moving the first suction nozzle closer to and away from the bag storage portion in the vertical direction are provided in the bag taking-out portion, and the first suction nozzle and the first suction nozzle moving mechanism are provided. By driving, the uppermost layer storage bag can be separated, and the separated uppermost layer storage bag can be hung and supported in an inverted posture with its opening portion facing downward. A pair of second suction nozzles that can suction and release suction around the part separately from the front and back sides of the bag,
A second suction nozzle moving mechanism that separates the pair of second suction nozzles from each other in the vicinity of the opening of the inverted storage bag is provided, and the second suction nozzle and the second suction nozzle moving mechanism are provided. The opening of the accommodation bag is configured to be openable by driving, and the start of adsorption of the accommodation bag by the second adsorption nozzle is set after the adsorption of the accommodation bag by the first adsorption nozzle and before the adsorption release. There is provided a nozzle control means for doing so.

[0007]

As described above, in the state where a plurality of storage bags are stacked in the storage bag, the vicinity of the openings of adjacent storage bags are in close contact with each other as described above. A slight gap is formed due to the swelling portion, and the wall thickness is thicker and heavier than the vicinity of the opening, and it is relatively easy to separate the vicinity of the bottom.

Focusing on such a point, according to the above construction, [a] the first suction nozzle is caused to suck in the vicinity of the bottom of the uppermost accommodation bag, and the first suction nozzle moving mechanism is operated. Thus, since the first suction nozzle is separated from the bag storage portion, only the uppermost one storage bag can be accurately separated from the lower storage bag.

[B] By operating the first suction nozzle moving mechanism, the suction-separated uppermost-layer storage bag is suspended and supported in an inverted posture with its opening facing downward, and the second suction nozzle By driving with the second suction nozzle moving mechanism, the second suction nozzle is sucked into the vicinity of the opening of the accommodation bag in the inverted posture from the front and back sides of the bag separately to open the opening, so that the opening is generally light and thin. A force can be evenly applied to the accommodation bag from both front and back sides, and the opening can be smoothly opened.

[C] In addition, the nozzle control means allows the second
Since the suction start of the storage bag by the suction nozzle is set after the suction of the storage bag by the first suction nozzle and before the release of suction, the storage bag is reliably delivered from the first suction nozzle to the second suction nozzle. Can be, for example, second
It is possible to save power as compared with the case where the suction start time of the suction nozzle is set before the first suction nozzle sucks the accommodation bag.

[0011]

As a result of the above action [a], it is possible to accurately separate only the uppermost storage bag of the multiple bags stacked in the bag storage unit from the lower storage bag. By the action [B], the opening of the accommodation bag can be smoothly opened, and the work efficiency of the opening work can be improved, and by the action [C], the power can be saved while the first suction nozzle is operated. (2) Since the accommodation bag can be reliably delivered to the adsorption nozzle, the workability of the accommodation bag separation operation, the opening operation, and the delivery operation from the first adsorption nozzle to the second adsorption nozzle can be improved. Power cost can be reduced.
