Description

[Detailed description of the invention] This invention relates to the improvement of a spring carrier, and more specifically, two guiding wheels provided on the weight side of the thread guiding part of the carrier, and a fixing wheel provided on the upper part of the guide shaft. The thread material pulled out from the bobbin is hung on the side guide wheel and guided, and the tension of the thread during braiding is absorbed by the two guide wheels on the movable weight side so as not to put stress on the thread. It provides a spring carrier.

In conventional spring carriers, the carrier runs along the guide groove during braiding, and when the carrier runs outside the guide groove, the thread is pulled out from the bobbin to a large extent, and when it runs on the inside of the guide groove, the thread is pulled out due to the difference in position. Only a small number of drawers are required, so unevenness always occurs in the drawer of the yarn, which also causes unevenness in the knitted string, which impairs the product value. The present invention is based on the above points.
In order to deal with this problem, two guide wheels are provided on the weight on which the thread moves to absorb the expansion and contraction caused by the drawer.

An embodiment of the spring carrier according to the present invention will be described in detail below with reference to the accompanying drawings.

Reference numeral 1 denotes a boat-shaped carrier body that moves along a guide groove provided in a guide plate.The upper plate 1' of this main body 1 includes a bobbin support rod 2, a vertical shaft 3 and a vertical shaft at a required interval. A guide shaft 4 is set upright adjacent to the shaft 3, and a weight 6 is inserted into the vertical shaft 3, which has two guiding wheels 5, 5' supporting the thread material Y at symmetrical positions. Furthermore, a tension spring 7 inserted into the vertical shaft 3 is provided on the weight 6. The upper part of the tension spring 7 is inserted into the upper part of the guide shaft 4, and the upper end is received by a pressing member 8 which is fitted onto the upper end of the upper plate vertical shaft 3 by applying a spring 16 from the upper part. is adapted to move up and down against the tension spring 7.

At the proximal end of the bobbin support rod 2 erected on the upper plate 1', a claw plate 9 having a claw part 9'' at the tip and a bent part 9' bent in a shape at the base end is oscillated. Possible axis 1
0, and the claw portion 9'' of the claw plate 9 is attached to a ratchet 11 provided on the lower surface of the bobbin B supported by the support rod 2.
It is designed to be separated from the Further, a connecting piece 12' from the float 12 inserted into the guide shaft 4 is connected to the bent portion 9' at the base end of the claw plate 9.

Therefore, when lifting the weight 6, the weight 6 floats 1.
When the upper end of 2 is hooked and activated, float 12
The pawl plate 9 connected to the guide shaft 4 swings around a shaft 10, and the pawl portion 9'' at the tip is separated from the ratchet 11.In other words, the thread material Y from the bobbin B is moved from the intermediate portion attached to the guide shaft 4. It comes to be guided by the guide ring 13 and pulled out.

The guide shaft 4 has a guide ring 15 on the upper part, and guide wheels 5, 5' provided on the weight 6 are positioned above the guide ring 15.
A guide wheel 14 is provided which is pivotally supported by the guide ring 15. Further, the lower part of the guide ring 15 is provided with the spring 1.
6 is provided to press the pressing member 8.

In the figure, reference numeral 17 is a spring that acts on the float 12 in a downward direction.

As is clear from the above-mentioned structure, in the present invention, the yarn material Y pulled out from the bobbin B that fits into the bobbin support rod 2 of the carrier body 1 running along the guide groove is attached to the guide ring in the middle part attached to the guide shaft 4. 13, and then through one guide wheel 5 attached to a movable weight 6, and then from the fixed guide wheel 14 provided on the upper part of the guide shaft 4 to the other guide wheel 5' of the lower movable weight 6. Guided by The weight 6 pulls up the float 12 against the spring 17, thereby separating the claw portion 9'' at the tip of the claw plate 9 connected to the float 12 by the connecting piece 12' from the ratchet 11 of the bobbin B, and releasing the thread material Y. It is designed to let out the thread material Y.
are the movable guide wheels 5, 5' provided on the weight 6 mentioned above.
The yarn is suspended and pulled by the fixed guide wheel 14 at the top, and the guide wheel moves less even if it pulls the same amount of thread material due to the principle of a movable pulley. In addition, since the pulling force is small, the threads are not strained and the threads are smooth, and since the size of the thread material Y that is pulled during braiding is absorbed by the guide wheel, the braiding can be done with a constant tension. , there are no spots on the braid, etc.
