Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a sock finishing machine,
The present invention relates to a method for pulling up a group of socks in a loosened state by being tucked up on a foot mold by a sock lifting device and delivering it to the next step.

[0002]

2. Description of the Related Art Conventionally, a group of socks heat set by a sock finishing machine, particularly thick socks such as socks, is tucked up on a toe and a group of socks is gripped by a chuck, and the chuck is moved toward the toe of the toe. Techniques disclosed in Japanese Patent Laid-Open No. 58-180665 and Japanese Patent Laid-Open No. 58-193217 are known as a technique for releasing the grip of the chuck and handing it over to the next step after the socks are simultaneously removed from the foot socks. ing.

In the former technique, socks extracted from a toe with a grip plate are separated into at least two sets by a stacking member and stacked in a bundle, and the other ends of the socks of the separated socks are collected. The portion is held by a holding member, and the holding member is inverted so that the toe portion side of the separated and accumulated sock is arranged to face downward with the release of the sock from the gripping plate and the accumulating member, and then the The sock is released from the holding member.

In the latter technique, a group of socks extracted by grasping the toes of the sock by the extraction chuck of the sock extracting device are bundled into a pair of sock plates of the sandwiching member so that the legs of the socks are bundled together. After gripping the sock, the sock grip of the extraction chuck is released, and the gripping plate is rotated by a predetermined angle to direct the toe part directly below, and then the sock is handed over.

[0005]

However, in the former technique, as shown in FIG. 2 of the sixth sheet of Japanese Patent Laid-Open No. 58-180665, the distance between the grip plates is the same as that between the foot molds, and Since the socks are extracted while keeping the distance between the toe parts of the toe, the extracted socks are separated into at least two sets and accumulated in a bundle. As shown, the central part of the lower end of the socks in the bundle state is long and both sides are short, and even if the socks in this state are held by the holding members and inverted so that the toe side of the socks faces downward, the lower side is In the state where the central portion is recessed and both side portions are long, the sock is released from the holding member, and in the next step, a pairing operation for equalizing the length of the sock is required. In addition, even when placed on a conveyor or the like, both long sides of the sock are bent to the recessed portion, and the bent portion is wrinkled because it is not sufficiently cooled immediately after heat setting, which is a quality problem.

Also, in the latter technique, Japanese Patent Laid-Open No.
-As shown in FIG. 6 of the sixth sheet of Japanese Patent Publication No. 193217,
The spacing between the chuck plates is the same as the spacing between the toes, and the socks are removed while maintaining the spacing between the toes of the toes, so the extracted socks are the center part of the lower end of the socks in the bundled state as in the former technique. Is long, and both sides are short.When releasing the sock grip of the extraction chuck and turning the gripping plate a predetermined angle to direct the toes directly below, the lower side is dented at the center and both sides are In the next step, it becomes a long state, so pairing work for equalizing the length of the socks is required. Further, even when placed on a conveyor or the like, both long sides of the sock are bent to the recessed portion, and the bent portion is not sufficiently cooled immediately after heat setting, which causes wrinkles, which is a quality problem.

The present invention was developed for the purpose of solving the above-mentioned problems.
