Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a yarn tensioning device, and more particularly to a yarn tensioning device which is fed from a bobbin and is supplied to a knitting machine in a circular knitting machine such as socks. .

[0002]

2. Description of the Related Art Generally, products such as socks, which are knitted by a circular knitting machine, are knitted from a bobbin for the purpose of eliminating a knitting defect of the product in order to knit into a uniform predetermined shape and size. The yarn supplied to the machine is applied with a preset tension and supplied to the knitting machine side.

FIG. 3 shows a yarn tension applying device that has been conventionally used for the above-mentioned knitting machine. This tension applying device is provided on upper and lower horizontal plates of a supporting substrate 1 formed in a U-shape. A pair of fixed thread guides 2 and 3 provided and a vertical plate of the support substrate 1 between the fixed thread guides 2 and 3 are provided, the tip of which is formed as a screw portion and a guide hole 4 of the thread Y is formed. A stepped pin 5, a pair of dish-shaped champons 6, 7 slidably fitted to the stepped pin 5, one champon 6 and a nut 8 screwed into the threaded portion of the stepped pin 5. It is composed of a spring 9 arranged between them.

In the conventional tension applying device constructed as described above, the yarn Y fed from the bobbin passes through the one fixed yarn guide 2, the guide hole 4 of the stepped pin 5 and the other fixed yarn. It is supplied to the knitting machine side through the guide 3.

Then, with respect to the yarn Y passing through the guide hole 4, the champons 6 and 7 are sandwiched from both sides, and the spring 9
One champon 6 is pressed against the other champon 7 by the urging force to apply tension to the yarn Y passing through the guide hole 4.

The tension of the yarn Y supplied to the knitting machine side can be arbitrarily set by adjusting the urging force of the spring 9 with the nut 8.

[0007]

By the way, yarns used in knitting machines for socks and the like have many fluffs because they are spun with short fibers. Therefore, during the winder process after spinning, there is no need for waxing or wax application. It has been processed.

Therefore, when the yarn treated in this way is continuously supplied for a long time, the wax or wax applied to the yarn becomes integrated with the cotton wool generated in the factory, and the inner surface of the champon. Cause sticking to the guide holes and the guide holes, resulting in uneven pressure contact of the champons and clogging of the guide holes, resulting in impaired maintenance of proper thread tension and poor knitting. It was.

Therefore, conventionally, the work of cleaning the champons and the guide holes of the tension applying device is regularly performed manually, but the number of tension applying devices per knitting machine is 10 to 20. There were several pieces, and due to the structure, cleaning the inner surface of the champon and the guide hole was extremely difficult, and it was a troublesome work that required labor and time.

The present invention has been made in order to solve the above-mentioned conventional problems, and has a structure capable of remarkably reducing the adhesion of wax, wax, and cotton dust applied to the yarn, and the interval of the cleaning period has been conventionally increased. An object of the present invention is to provide a yarn tension applying device that is longer (about 5 times) than the device and that can reduce and shorten the labor for the cleaning work.

[0011]

In order to solve the above-mentioned problems, the present invention provides a pair of fixed yarn guides at appropriate intervals on the traveling line of the yarn fed from the bobbin. Between the fixed thread guides, a fixed plate and a movable plate are arranged on both sides connecting the center line of the fixed thread guides. The movable plate is supported by a spring force so that the movable plate can be pressed against the fixed plate surface. It is configured so that it can be widely separated from the fixed plate.

[0012]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, the yarn tension applying device of the present invention is installed at an appropriate position on the traveling route of the yarn Y which is fed from the bobbin and supplied to the knitting machine (not shown). Has a U-shaped support substrate 10, and a pair of fixed thread guides 11 and 1 are provided on the upper and lower horizontal plates 10a and 10b of the support substrate.
2 is provided, and on both sides between the fixed thread guides 11 and 12 that connect the center lines of the fixed thread guides 11 and 12, a fixed plate 15 fixed to the vertical plate 10c of the support substrate 10 and a rotating plate. A movable plate 16 attached to 21 is arranged face-to-face.

The rotating plate 21 is made of a plate-shaped material formed in a C shape as shown in FIG.
While loosely engaging the two pins 22, 22 with 6 attached,
A screw 23 is provided in the central portion, and a spring 25 is arranged between the nut 24 that is screwed into the screw and the movable plate 16 so that the movable plate 16 is constantly fixed by the urging force of the spring. It is constructed so as to be pressed against one surface. By adjusting the urging force of the spring 25 with the nut 24, the pressure contact force of the movable plate 16 with respect to the fixed plate 15 (giving tension to the yarn Y) is arbitrarily set.

Further, the rotating plate 21 has a protrusion 21a on its upper portion, and the protrusion is fitted into a recess 26 formed in the upper horizontal plate 10a of the supporting substrate 10 and has a lower end. Shaft 27 provided on the lower horizontal plate 10b
Pivot to.

Therefore, the protrusion 21a fitted in the recess 26 of the upper horizontal plate 10a is artificially released to move the rotary plate 21 to the position shown in FIG.
By rotating the shaft 27 around the shaft 27 from the solid line position (working position) to the chain line position (non-working position), the movable plate 16 can be widely separated outward from the fixed plate 15.

The yarn tensioning device of the present invention is constructed as described above, and the yarn Y fed from the bobbin first passes through the fixed yarn guide 11 on the inlet side and then passes between the fixed plate 15 and the movable plate 16. After that, it reaches the fixed yarn guide 12 on the exit side and is supplied to the knitting machine.

Therefore, the yarn Y supplied to the knitting machine is in contact with the fixed plate 15 and the movable plate 16 by the urging force of the spring.
The tension is applied by the surface pressure action of 1. As a result, it is possible to always provide the tension in a stable state as compared with the conventional tension application by the action of the guide hole and the champon.

Further, when cleaning the wax and the cotton dust on the surfaces of the fixed plate 15 and the movable plate 16, the movable plate 16 is separated from the fixed plate 15 by a large distance together with the rotary plate 21 for cleaning. The cleaning work can be easily performed in a short time.

[0020]

As described above, according to the present invention, a tension is applied to the yarn supplied to the knitting machine by the surface pressure action of the fixed plate and the movable plate. Compared to the structure with holes and champons, the adhesion of wax and cotton wool can be significantly reduced, and the movable plate can be widely separated from the fixed plate. It is possible to easily and surely perform the cleaning work of the wax and the cotton wool attached to each surface of the plate and the fixed plate.
