Abstract

PURPOSE:To automate a thick socks finishing machine and eliminate wrinkles due to folding of the end of socks by receiving socks from a pull-out chuck which releases plural pairs of socks one by one and delivering a plural number of bundled socks to the next process position while maintaining the condition which the ends of socks are aligned evenly and bundled. CONSTITUTION:First, a pair of socks 2 among plural pairs of socks 2 which are pulled out by a pull-out chuck 10a are received by a delivery chuck B in the vertical condition and transferred to the next process position by lowering them while grip of the socks 2 is changed to the horizontal condition to put the socks 2 at the position and press the socks 2. Next, after grip of the socks 2 of the delivery chuck B is released and the socks 2 are shifted to the next process position, the delivery chuck B is restored to the original position and moved to the position of the next pair of socks 2, and the motion which receives the next pair of socks 2 and transfers them to the next process is repeated. Thus, it is possible to automate a thick socks finishing machine and eliminate wrinkles due to folding of the end of socks.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of receiving thick socks, such as socks, which are divided into a plurality of sets by a take-out chuck of a sock take-out device in a sock finishing machine, one set at a time and transferring them to the next process position and delivering them. It relates to the device.

[0002]

2. Description of the Related Art Conventionally, as a technique of extracting a group of socks with a sock, such as socks by a sock extracting device, and handing it over to the next step, Japanese Patent Laid-Open Nos. 58-180665 and 58-193217 are disclosed. Things are known.

In the former technique, a group of socks extracted from a toe with a grip plate is separated into at least two sets by a collecting member and collected in a bundle, and the other ends of the separated socks are also separated. Is held by a holding member, and the holding member is reversed with the release of the sock between the holding plate and the accumulating member, and the toe side of the separated and accumulated socks is arranged to face downward, and then the grasping is performed. The sock is released from the member.

In the latter technique, a group of socks extracted by a sock extracting device are bundled into a pair of sock plates of a sandwiching member so that a plurality of socks are bundled and the legs of the socks are grasped, and then the socks are grasped by an extraction chuck. The sock is handed over after the claw plate is rotated by a predetermined angle to direct the toe portion directly below while releasing the sock.

[0005]

However, since the knitted fabrics of socks for men, casual wear, sports wear, etc. are thick and bulky, JP-A-58-180665, page 4, left column, lower row, 14th line, Although it is described in line 15 that two sets of uniform bundles are separated and accumulated, in practice, as shown in FIG.
It cannot be uniformly bundled like the women's thin boots described in Japanese Patent No. 23456. Therefore, since the central part of the lower end of the sock in the bundle state is long and both sides are short, and the central part of the upper end of the sock is short and both sides are long, the socks are released from the holding member, and socks are paired in the next step. It is necessary to perform pairing work to align the length of socks. Even when placed on a conveyor for transporting to the next process, the long sides of the socks bend to the recesses, and the bends are not sufficiently cooled shortly after heat setting, causing wrinkles and a quality problem. Has become. Also, in the latter technique, the sixth technique disclosed in JP-A-58-193217 is disclosed.
As shown in FIG. 2 on the page, the intervals between the chuck plates are the same as the intervals between the toes, and the socks are extracted while maintaining the intervals between the toes of the toes.
Similar to the former technique, the central part of the lower end of the bundled socks is long and both sides are short, and it has the same problem as the former.

Therefore, the present applicant has developed a technique for solving the above-mentioned problems and filed a patent application on August 7, 1992. In this technique, when pulling out thick socks such as a group of socks that have been tucked up on a toe by a sock tucking device from the toe and handing it over to the next process, a group of socks are brought close to each other in the center and gripped. , A plurality of sets of extraction chucks each having a releasing chuck plate are provided in series and reciprocally movable in the direction of the toe of the toe, and a group of socks tucked up on the toe by the above extraction chuck is provided for each plurality of sheets. Separate and separate the chuck plates to the center of each group, hold the socks together with the center of each group together with the tip of the foot model, and move the extraction chuck in the direction of the toe of the group of socks to form a group of socks. The grip is released for each set and is handed over to the next process. By doing so, the bottom ends of the shoes bundled for every multiple sheets are aligned without any unevenness, so even when putting them in the next process, there is no bending in the recesses, and the worker does extra work of pairing. The above-mentioned problems could be solved without having to do so.

However, when a plurality of pairs of socks, which is a feature of this technique, are released by grasping each pair and handed over to the next step, there is no technique for receiving the socks for each pair and transferring them to the next step position. It was hindering the automation of thick sock finishing machines.

The present invention has been developed for the purpose of receiving one set of socks from the extraction chuck for releasing the grip of the one set of socks and delivering it to the next process position while maintaining a uniform bundle state. It was done.

Then, a group of socks 2 is divided into a plurality of sets, and a plurality of sets of socks are brought close to each other and held by the central portion of each sock. Multiple pairs of socks pulled out 2
First, in a vertical state, the delivery chuck B goes toward the front and receives it from the extraction chuck 10a. Then, the holding state of the sock 2 is converted into a horizontal state, and the delivery chuck B is lowered to move to the next process position K ( (Boxing, conveyor, packaging process), and then the socks 2 are placed on the next process position K at that position and the sock pressing means I
To press the sock 2 on the next process position K, then release the sock grip of the delivery chuck B, replace the sock 2 on the next process position K, and then, move to the sock pressing means I and the delivery chuck B. And the return chuck lateral moving means J are operated to move the delivery chuck B to the next pair of socks, and the next pair of socks 2 is extracted from the delivery chuck 10a. The operation of receiving and transferring to the next process position and replacing the sock 2 on the next process position K is sequentially repeated.
