As is well known, the use of disposable plastic bags is becoming more common in recent years, and when such disposable plastic bags are packaged or taken out for use, several sheets of plastic bags are folded and placed in a paper box or pack. It is common to unpack one by one while unpacking a roll-shaped plastic bag that is packaged to be taken out and used for long periods of time, or is formed continuously.

Recently, however, there have been attempts to use plastic bags in the form of long plastic bags in continuous form, put them in boxes, and draw them out one by one like tissues (Utility Model Registration No. 392799). In order to put the plastic bags into the box so that they can be drawn out one by one, the continuous plastic bags must be folded and stacked one by one.If the plastic bags are folded by hand, the efficiency is low, productivity is lowered, and the cost is expected to increase. It was difficult to fold evenly from the beginning to the end when folding the formed plastic bag, there was a problem that the quality is degraded, such as not being drawn well one by one in turn.

On the other hand, in order to solve this problem has been proposed a folding lamination apparatus of a continuous plastic bag formed in Patent Registration 10-0605477, Looking at the technical configuration, a plurality of belts 14 are hanging and a constant timing interval by the servo motor 15 A conveying device unit 10 having an upper roller 11 and a lower roller 12 so as to repeat the intermittent feeding operation by the length of one piece of the plastic bag 100; Pedestal 21 to form a cut portion 102 to cut and leave only a portion at a position immediately next to the junction portion 101 of the plastic bag 100 at the position where the plastic bag 100 is supplied by the transfer device unit 10 Cutting device portion 20 consisting of a blade 22 for elevating above; The stacking device portion 20 is formed next to the stacking device portion 30, but the lower portion supports the plastic bag 100 to be folded and is connected to a known mechanical lifting means 32. Pedestal 31 is configured to be lowered little by little as the bag 100 is stacked; A pressing plate 34 for pressing the plastic bag 100 which is folded while repeating the ascending and descending by known lifting means at the same timing as the cutting blade 22 on the upper portion thereof; The suction pipe 35 is formed between the cutting device unit 20 and the stacking device unit 30 and the suction hole 36 is formed.
