Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an apparatus for manufacturing synthetic resin carrier bags that can be easily packed with products and served together with the products in supermarkets and the like.

[Background of the invention]

In general, this type of carrier bag is thin, and many bags are stacked together and placed in an outer bag during manufacturing, so it is difficult to remove them if you leave them on a shelf near the cash register and take them out one by one from the outer bag. It was time consuming and troublesome.

For this reason, in recent years, at the stage of manufacturing this bag, a cut-off hanging margin is made at the opening of the bag, a punch hole is punched in the hanging margin, and the bag can be hung from a hook provided on a cash register stand, etc. This has the advantage that the lower end of the bag comes apart, making it easier to take out each bag one by one. However, with punched holes in the hanging allowance, each bag is not tied together, so when the bundle of carrier bags is taken out from the outer bag, it may fall apart, and as mentioned above, the bag may fall apart. A secondary problem arose in that it became difficult to hang it in the room itself.

In order to solve this secondary problem, recently, a melting hole that also serves as a hanging hole is made in the hanging margin to join the bags one by one to prevent them from falling apart. 167829) is proposed.

[Problem to be solved by the invention]

However, the conventional bag in which the above-mentioned hanging margin has a melting hole that also serves as a hanging hole is obtained by providing a tube-shaped continuous body with double rows of horizontal seals at appropriate intervals, and cutting between the adjacent horizontal seals. When stacking the two-end seal bodies, a melting hole that also serves as a hanging hole is simultaneously bored in the hanging margin left in the punched area. Therefore,
After lamination, when being gripped and conveyed from the lamination section to the punching section,
There were many defective products, such as the melted part peeling off, the laminated state collapsing, and the melting hole being cut off during punching in the punching area.

The above-mentioned problems of this invention are solved, and the stacked state does not collapse not only during stacking but also during transportation.
To provide a manufacturing device for a synthetic resin carrier bag that can eliminate the occurrence of defective products by accurately opening a hanging hole at an appropriate position in a hanging allowance part, and that does not take much time to collect.
