Description

[Detailed explanation of the idea] The present invention relates to a spring carrier weight.

The spring carrier of a lace-making machine operating at high speed has an intermediate thread guide that guides the thread from the bobbin, and a weight that guides the thread to the upper part by hooking the thread guided by the intermediate thread guide. A thread hook is provided and a thread guide 2 is provided at the tip leading to the braiding section, and the entire braiding is performed with the thread guided by the thread guide as the carrier runs.

In particular, conventional weights are made entirely of press-formed iron plates and are easily deformed and deformed due to being used during heavy use.If the thread breaks, the weight must be inserted into the insertion rod through which the weight metal is inserted. When it falls along the line and comes into contact with the automatic stop lever of the lace making machine, the stop lever fully releases the clutch and stops the operation, but there is wear due to contact with the lever and wear due to vertical movement.

Furthermore, the hook part of the thread hook is a copper piece formed into a hook shape using a press, and is then plated with hard chrome or copper.

However, during high-speed operation, it suffers from severe wear and cannot be used for a long time.

In view of the above points, this invention has been improved to deal with this problem, and is made of 5 synthetic resin and fitted into the fitting hole of the weight together with the deformed cage waste to increase durability and fit into it. The lifespan of the insertion rod is increased by 4, and the hook member is made entirely of alumina porcelain to ensure durability.

That is, it is intended to enable mass production, smooth operation, and durability.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a spring carrier weight according to the present invention will be described in detail below with reference to all the accompanying drawings.

Reference numeral 1 denotes a weight main body molded from a synthetic resin material, and the main body 1 has a guide portion 34 having a vertical through-hole made of two gold protruding upward.
Further, the pin receiving piece 4 is fully protruded from the measuring portion of the through hole 2, and the thread hook is fully bored through the insertion hole 6 of the member 5, and weight portions 7 projecting downwardly on the left and right sides are integrally molded with metal.

The through hole 2 has stepped portions a at the top and bottom of the inner wall. bk, and bushes 8 and 94 are fitted into the stepped portions a and b, respectively.

The thread hook is the member 5, the thread hook is the hook 5', and the insertion hole 6V.
c Ashing insertion part 5 is fully formed and molded with alumina porcelain,
A 10-karat gold pin hole is drilled in the insertion portion 5, and a pin 11' is inserted into the hole 10 through the hole 114 drilled in the pin receiving piece 4. After insertion, the thread hook is locked in the insertion hole 6 of the member 5.

This thread hook member is attached with a pin as described above, but it is sometimes buried at one end during molding.

Figure 5 shows a carrier made of 12-carat gold, which is fitted into a guide groove provided on the machine base and slides, with a support rod 15 supporting a bobbin 14 on the upper surface of the main body 13, and a support rod 15 on a rack support stand 16. An insertion rod 17 is provided upright and extends parallel to the support rod 15 to guide the entire insertion of the weight body 1, and a stopper is provided with an 18-karat gold pawl that engages the ratchet teeth 14' of the bobbin 14 supported by the support rod 15. The guide rod 214 of the actuating frame 20 is erected with the piece 19, and the entire flat end thereof is connected to one end of the piece 19, and the entire upper end thereof is related to the weight body 1.

The insertion rod 17 is provided with a compression spring 22□ that acts on the weight body 1, and the guide rod 21 is provided with a thread Y from the bobbin 14.
A compression spring 244 is provided between the intermediate yarn path guide 23 and the operating frame 20.
It is a provision.

The entire intermediate portion of the straight piece 19 is pivoted on the support base 16, and the pawl 18 at this end is moored facing the ratchet teeth 14' of the bobbin 14.

That is, the operating frame 20 is guided by the guide rod 21, and is pulled up by the thread Y from the bobbin hooked on the hook 5' of the thread hooking member 5 of the weight body 1 guided by the insertion rod 17 and the guide rod 21. When the weight body 1 is pulled up against the spring 24, the stopper piece 19 connected to the lower end of the operating frame 20 vibrates constantly, and the 18-karat gold pawl that engages with the ratchet teeth 14' of the bobbin 14 is removed. It is something.

25 is a thread guide attached to the upper end of the guide rod 21, and 26 is a reinforcing piece.

In the present invention, with the above-mentioned configuration, the carrier travels all the way, the intermediate thread guide 23 attached to the middle part of the guide rod 21 guides the thread from the bobbin 14, and the thread Y is inserted into the weight main body 1. The stopped thread is guided by being hooked to the hook 5' of the member 5, and the thread Y is further guided to the thread guide 25 attached to the upper end of the guide rod 23 and braided by the running of the carrier. However, if the thread Y breaks during braiding, the insertion rod 17
Since the weight main body 1 that is fitted into the thread hook 5' of the thread hook 5' is no longer tensioned by the thread YK, it falls along the insertion rod 17 by the spring 22, and the operating frame located at the bottom. 20 is pressed down together with the spring 24 acting on the operating frame 20, and the claw 18 of the stopper piece 19 associated with the operating frame 20 stops the bobbin 14 from being fed out. The automatic stop lever installed on the medium lacing machine stops the machine from running.

In addition to the above, the present invention has an insertion rod provided on the carrier that protrudes upward into the guide portion having a vertical through-hole for insertion,
Furthermore, there is a weight main body 4 made of synthetic resin material which is formed to protrude downward from the entire weight part on the lower left and right sides, and on the upper surface of this main body there is a weight body 4 made of alumina porcelain with a spacer placed on the side of the guiding part. The formed thread hook is equipped with a hook 4, and the thread hook is attached to the upper part of the member 4.
Furthermore, the through-hole has a carrier medium weight that is completely fitted with a bushing on the inner wall, and is molded from a synthetic resin material, so it is more rigid than the conventional pressed steel plate structure and does not deform. .

Therefore, the movement of the insertion lever is smooth, and mass production is possible.

Furthermore, there is less wear and tear on contact with the automatic stop lever.

In addition, since the thread hook made of aluminum porcelain is entirely attached to the Naro weight body made of synthetic resin material, there is less wear on the thread and the hook is durable.

Furthermore, since the through hole into which the insertion rod is inserted is fitted with four bushings, the durability of the through hole due to vertical movement is increased, and the life of the insertion rod is also extended.
