Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic device for turning continuously knitted sock fabric, dividing it, and cutting the toe part, and an insertion tube for covering a continuous band of sock fabric, and an insertion tube for covering the sock fabric in a continuous band shape. A turning device is equipped with a pressing roll that slides the sock fabric into the inner part of the insertion tube by sliding it freely toward and away from the sock fabric placed on the sock fabric, and the sock fabric is turned over in advance by turning the sock fabric over the bottom and toe of the sock fabric. A pulling section with an upper blade and a lower blade that locks and pulls together the stepped part formed at the boundary between the thin, separate course and the thick welt part, which are knitted in series in several courses, and the pulling part. A pulling and cutting device has a cutter installed on a slidable platform to cut separate courses of the stocking fabric, and a film is formed at the boundary between the thin toe of the stocking fabric and the separate course, and runs parallel to the guide member. On each board of the slat conveyor, a cylindrical fastening member is installed horizontally in a direction perpendicular to the guide member, and the toe portion of the sock material is inserted into and held at a distance from the board. A linking device is provided above the slat conveyor, which grips the sock guide member so as to be able to freely approach and separate the sock guide member, and which is placed parallel to the cut sock guide member on the plate and which removes the toe portion that protrudes upward from the clamp member. A movable roller device that is fitted into the attachment member and slides the toe portion against the V-shaped sock to release the attachment, and a sock suction device that is detachably fitted to the open end of the attachment member. The gist is that the conveyor was installed close to the end of the slat conveyor.

Conventionally, double-cylinder sock knitting machines knit sock fabric into continuous strips, so it is necessary to separate each leg one by one.To separate the socks, a thread removal course, a waste knitting course, and linking are performed at the boundary between the welt and toe sections in advance. It is necessary to knit each course, and the manual work of cutting the threads of the thread removal course with scissors and removing the threads to separate them is troublesome and has low work efficiency.

Therefore, it was necessary to turn the sock fabric inside out in advance in order to prepare the linking process to remove the toe part of the separated socks, and after the linking process was completed, the socks were separated again in preparation for the steam setting process. The sock must be turned inside out, with the front knitted fabric facing up.

The present invention has been provided in view of the above circumstances, and includes a process of turning over the sock fabric continuously knitted into strips by a double cylinder sock knitting machine, a process of dividing each leg one by one, a linking process, and a process of changing the front knitted fabric. The turning process is carried out manually by one worker, who inserts it into the insertion tube during the first turning process, and manually inserts the separate course, which has been knitted in advance, into the turned-over sock fabric into the 1st position of the alignment cut zone. Everything else operates automatically, and the purpose is to improve work efficiency, reduce the number of workers, save knitting yarn, and shorten knitting time.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. A strip of sock fabric (11) continuously knitted by a double-cylinder sock knitting machine will be described in detail with reference to the drawings.
