Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a sock finishing machine in which two adjacent pairs of socks are attached to and set on a group of foot lasts that are erected and supported on a carriage in a sock finishing machine. This relates to a method of sequentially removing one pair from a foot mold, including the toe part of the mold.

PRIOR TECHNOLOGY A technique similar to the conventional technique of pulling out socks set in a sock finishing machine one by one from the last by matching the toe portions of two lasts was developed in Japanese Patent Application Laid-Open No. 1986-
No. 186659 is known.

This technique involves folding an upright panty-taste finishing foot last into which socks are inserted in half at the center in the width direction, overlapping the templates with an appropriate distance, and then inserting the socks. Fold the sock in half, pull out the overlapping template of the half-folded foot last, and use a pair of gripping arms of the assisting member to sandwich the sock along with the sock at both sides in the width direction. By raising a pair of gripping arms along the foot-shaped template, the toe portion of the sock folded in half escapes from the foot-shaped template above it;
By sandwiching the toe of the sock that has escaped and rolling it up between a pair of rollers, the sock can be folded in two and removed from the last.

Problems to be Solved by the Invention However, in this technology, the foot-shaped templates are transported one by one at regular intervals in a diffused state, and the foot-shaped templates are once stopped, and while they are stopped, the socks are pulled out one pair at a time. It cannot be used for a group of foot-print templates (referred to as foot-prints in the present invention) that are grouped together with even a small gap between them. That is, the superimposed templates of the half-folded foot lasts are extracted and held together with the sock at both widthwise edges of the assisting member by a pair of gripping arms. When used on a foot last, the sock cannot be pinched because it comes into contact with adjacent foot lasts that are clustered together at a narrow interval, and therefore the toe of the sock cannot be moved from the foot last past the foot last. I can't get it to escape.

Furthermore, with this technology, the foot last templates are spread out one by one at regular intervals, so it is possible to fold the foot last in half and overlap the templates.
It is said that the distance between the two shoe prints in the group of older brother prints that were gathered together was so narrow that it was not possible to fold the lasts in half and overlap the templates, and therefore it was not possible to make two templates into a pair. There are problems.
