Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an object distributing device for moving and distributing a plurality of objects such as putting them in a bag.

[0002]

2. Description of the Related Art For packaging a granular material such as rice, a few k
2. Description of the Related Art Bags are measured and weighed in units of about g. In this case, the larger the unit of measurement, the easier the handling during transportation. Therefore, a plurality of small bags are collectively stored in a large outer bag, and the outer bag is handled as one bag during transportation.

In order to store a plurality of small bags in an outer bag, it is necessary to place the small bags in a predetermined arrangement pattern and insert the small bag into the outer bag with the arrangement pattern kept. As a conventional object distribution device for this purpose, for example, Japanese Patent Laid-Open No. 62-2
There is one disclosed in Japanese Patent Publication No. 08328.

That is, as shown in FIG. 5, the suction conveyance device 1 descends and the two suction plates 2 and 2 are respectively brought into contact with the pouch 3 at a predetermined suction position to suction the two pouches 3. To do. The suction conveyance device 1 moves up and simultaneously pulls up the two pouches 3. When the suction conveyance device 1 moves to the position where the pouch 3 is packed in the outer bag, the suction conveyance device 1 descends and places the pouch 3 at the packing position. The placed small bag group is pushed by the pressing plate and inserted into the outer bag.

When the small bag group is placed, the vertical and horizontal directions can be changed alternately so that when the small bag 3 is packed in the outer bag, the small bags are less likely to be displaced in the outer bag and are stable during stacking during transportation. It is effective in increasing the degree of damage and reducing the risk of cargo collapse.
