Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an article turning device, and more specifically, to
The present invention relates to the provision of a new device for turning over semi-finished clothing products such as tubular sewn clothing products, tubular cut pieces, and tubular sewn products made of flexible sheet materials such as knitted fabric products using suction means.

In the textile industry, many articles are woven inside out with the inside out, and then turned again with the right side out before the next step in manufacturing the final product or before putting the final product on the market. I have to get it out.

For example, many cylindrical clothing items such as the sleeve openings of pants, shirts, pants, pajamas, shirts, pants, etc. are usually sewn with a seam on the outside using a sewing machine. It becomes necessary to turn the article inside out in order to place the seams inside the article.

This flipping process is usually done manually, with or without a flipping tool, and is a very time-consuming process at best.

In addition, since the shapes of articles vary widely, it is troublesome to make each turning tool suitable for each shape of the article.

From this point of view, there is a need to mechanically perform the turning operation of articles, and there is a pneumatic turning device, for example, as disclosed in Japanese Patent Publication No. 45-9916.

Although this conventional pneumatic flipping device has certain advantages, it requires manual feeding of articles into the nozzle assembly and requires manual gripping of the articles during flipping. At the last step, there were some problems with automation.

Furthermore, in the conventional example, an article that has been turned inside out is folded,
No consideration was given to post-process work such as stacking, and it was a step forward in terms of efficiency.

Therefore, the present invention has been devised for the purpose of utilizing or maintaining the advantages of the conventional pneumatic turning device while eliminating its disadvantages. An inside-out cylindrical body having an inner surface shape that conforms to the unfolded form is provided with an article loading port and a suction section that passes through a suction mechanism, and an article gripping member having a gripping section that can hold and release a cylindrical clothing article is attached to the gripping section. It is provided so that it can be moved away from the article loading port within a sufficient range to pull out the article inside the cylinder and can be freely approached.

Furthermore, a second feature of the present invention is that, in addition to the first feature, an article stacking table for stacking tubular clothing articles in a folded manner by interlocking and cooperating with the article gripping member is an inverted cylindrical body. The point is that it is provided corresponding to the article loading port.

Furthermore, a third feature of the present invention, in addition to the first feature, is that an article stacking table for stacking cylindrical clothing articles in conjunction with the article gripping member is adapted to load cylindrical articles upside down. The main feature is that a conveyor is provided corresponding to the opening and conveys the articles to the article stacking table.
