Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a device for feeding a sock fabric with an unstitched toe portion to a linking machine that overstitches the toe portion of socks or the like.

``Prior art'' In contrast to the method of transferring stitches from the unsewn toe of a sock to the point needle of a circular linking machine and overstitching, a linking machine using a series method that does not require a point needle has been provided (Tokuko Showa). 57−
11236) In the same invention, a sock fabric holding tool is formed by fixing a pair of guide plates to a bracket protruding from one end of the substrate with a gap between the opposing sides to insert the sock fabric. A pulley is provided on the back surface of each guide plate, and a pair of pulleys is provided on a bracket that projects sideways on the other end of the board, and an endless belt is hung over the pulleys provided on the guide plate to form a conveyor. The endless belts run close to each other on opposite surfaces that clamp the toe portion of the sock fabric, and insert several thin linking courses, which have been knitted in advance on the toe portion of the sock fabric, into the gap between the clamping tools. As the conveyor runs, the waste section is first sent to a cutting device installed on the board and cut, then sent to the first linking machine installed on the board to be sewn together, and finally the second section is cut.
By feeding the material to a linking machine and performing lock stitching, the open toe portion of the sock fabric is overstitched, and at this time, a linking course of approximately the same width as the wall thickness of the guide plate is sewn on the opposite side of the guide plate. The correct position is to hold it between the sides.

``Problem to be solved by the invention'' The guide plate is integrally fixed to the substrate via a bracket, and the width of the linking course that is knitted in advance on the toe of the sock fabric is large enough to fit the needle of the sock knitting machine. Since the guide plate is knitted in various ways depending on the number (gauge number) (if the gauge number is small, the stitches will be coarse and the width of the linking course will be large; if the gauge number is large, the stitches will be fine and the width of the linking course will be small). If the width of the linking course is larger than the thickness, it will protrude downward from the lower surface of the guide plate, and if the linking course is sent to the sewing machine in an incorrect position where it is too low, it will not be possible to link in the correct position, resulting in defective products. In this invention, a guide plate that holds the linking course is attached to the board so that it can be raised and lowered.
The purpose is to adjust and fix the guide plate in the correct position according to the width of the linking course, and to link in the correct position to produce good products without loss.

"Means for Solving the Problem" Guide rods are set up at both ends of the pedestal that is attached to the board, and a bracket is attached to each guide rod so as to protrude to the side of the pedestal so that it can be raised and lowered, and a pair of brackets are installed on the lower surface of the protruding part of the bracket. Each of the forked leg rods is vertically installed, and a pair of guide plates are attached to the lower surface of the forked leg rod by maintaining a gap between the opposite sides thereof into which a linking course knitted in advance in the sock fabric is inserted. An endless conveyor line that clamps and conveys the toe of the sock fabric that has been fixed and inserted into the gap is installed facing each guide plate, protruding to the side of the board, and having one end placed below the endless conveyor line. By installing another endless conveyor line positioned at The guide plate is raised and lowered, adjusted to the correct position, and fixed to ensure accurate linking.

``Operation'' Therefore, according to the present invention, the unsewn toe portion of the sock fabric is grasped with fingers and inserted into the gap between the guide plates, and the toe portion opening of the sock fabric is moved toward the opposing surfaces of the pair of endless conveyor lines. When clamped, the sock fabric is conveyed by the running of the endless conveyor line, and then transferred to another endless conveyor line installed below the endless conveyor line, where the sock fabric is opened using a cutting tool provided on the board. Then, the first linking machine and the second linking machine provided on the board perform bulk stitching and lock stitching to complete the linking and stitch the toe part.

``Example'' Below, an example of the present invention will be described in detail with reference to the drawings.As shown in FIG. 3, the bracket 4 is fitted above and to the side of the pedestal 2 so as to be able to rise and fall freely, and the forked leg rods 4a, 4 are attached to the lower surface of both ends of the protruding part of the bracket 4.
