Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for folding and packaging socks, particularly high socks (referred to as below-the-knee stockings), seamless stockings or pantyhose.

Packaging for sock products is done by folding the socks by wrapping them around a cardboard mount used as a packaging core material to prevent the wrapped product from losing its shape as the sock material is extremely soft. Either wrap the folded socks in a leaflet-like decorative paper with the product name, promotional slogan, etc. printed on it, or omit the cardboard mount and use only tri-fold decorative paper with the first and second fold lines. After folding the socks on the decorative paper and folding the decorative paper along the first and second fold lines and wrapping the folded socks with the decorative paper, a transparent synthetic resin packaging bag is placed. After that, the opening of the packaging bag is folded back and sealed with adhesive tape or the like to complete a single sock packaging product. Currently, in order to streamline the socks packaging process and save on packaging materials, packaging-U, which uses only the latter three-fold decorative paper, is the mainstream. Therefore, when folding and packaging socks using this tri-fold decorative paper, the conventional cardboard mount and the process of supplying the mount can be omitted.

However, in the work of folding and packaging socks using the trifold decorative paper mentioned above, the socks are folded onto the mount part of the decorative paper, and then the cover part of the decorative paper is folded along the first and second fold lines. Since the folded socks are folded in and the ear edge portions are folded in, the folded socks are wrapped in the mount portion, and the socks are inserted and filled into the packaging bag, the operation is complicated and requires many steps.

In the past, several methods have been proposed for automatically folding and packaging socks using such packaging materials, but as mentioned above, folding and packaging socks products is difficult due to the softness of the sock fabric. These methods are extremely complex and difficult, and require a large number of work steps, resulting in low operational reliability and extremely complex structures, so none of them have a significant practical effect. The reality is that it is not.

It is an object of the present invention to solve the above-mentioned conventional problems and to perform the folding and packaging work of hosiery products almost automatically with high efficiency using the above-mentioned tri-fold decorative paper.

Another object of the present invention is to provide an automatic device for folding and packaging the hosiery products, which has high operational reliability and is structurally simple.

That is, in the present invention, the central part of the leg of the sock is held in a substantially stretched state by suction on one holding/suction assembly, and both side parts of the sock are placed on a pair of conveyor members. The sheet of decorative paper is then transferred to the next work station run while maintaining the same shape, and here the decorative paper supply mechanism folds a piece of decorative paper of a predetermined shape along the first crease line, and the mount part is folded into the sock that is being held under suction. After being supplied onto the center part of the leg, both sides of the sock are folded back and overlapped onto the backing part of the supplied decorative paper, and then the decorative paper is folded along the first fold line. While folding the cover part and the mount part onto the folded sock and transferring it to the next work station, the edge edge of the decorative paper is folded downward along the second fold line by the inserting member, and then the edge edge of the decorative paper is folded downward along the second fold line. While transporting the folded decorative paper and folded socks over the holding suction assembly and onto the conveying member, the edge of the decorative paper was folded into the lower surface of the folded socks, and in this way, they were wrapped in the 1.1 paper. The folded socks are inserted and filled into a packaging bag which is in a standby state in advance.
