Description

The present invention relates to a straight type vacuum packaging device capable of reducing the occupied area by arranging a plurality of parallel bagging and packaging work lines in a straight line with an extremely small width.

Conventionally, it has been known to arrange a bagging device in a substantially straight line so that bagging until the articles are packed in the bag can be automated with the bag mouth of the zipper bag opened (Patent Documents). See 1).
In this known technique, when clothes are placed on the article holding table, the bag is taken out from the adjacent stocker to the set table, the bag opening of the chuck bag is opened, and the article holding table is put into the bag together with the clothes on it. After being inserted, only the article holding table is pulled out, the chuck bag into which the clothes are inserted is sent from the set table to the horizontal feeding table, and the horizontal feeding table on which the chuck bag is placed slides sideways to move the chuck bag. It is a bagging device in which the bag mouth is closed by a press roller.

In addition, it has a compact structure developed by the present applicant that fits within the transfer range of the supply conveyor, and the bag held by the suction holder does not come off due to the air pressure blown from the bag mouth, and together with the bag opening holder. There is known a bagging and packaging device that performs bagging by inserting an object to be packaged into a bag (see Patent Document 2).
In this known technique, a bagging portion is provided in parallel facing a plurality of bag opening holders transferred by a supply conveyor, and a plurality of pairs of a suction holder at the upper part and an empty bag holder at the lower part of the bagging portion are arranged. The bagging and packaging device is provided with a carry-out table that can move forward and backward at an intermediate position between the suction holder and the empty bag holder.

The bagging device of Patent Document 1 of these known techniques supplies an empty bag from a stocker arranged horizontally, and closes the chuck bag opening by sliding the horizontal feed table sideways, and the device is installed. The bagging and packaging device of Patent Document 2 has a large bagging section in a direction orthogonal to the transfer direction of the supply conveyor, and has a large bagging width, and the carry-out table has a bag mouth closed. The entire bagging and packaging line is not completed.
Therefore, in these known techniques, the bagging devices are arranged almost in a straight line, but both of them have a layout in which the occupied area of the bagging device cannot be made compact.
