DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a braiding device for braids, electric wires, wires, and the like, and has been developed for the purpose of increasing the speed of braiding and preventing noise.

[0002]

2. Description of the Related Art As one type of braiding apparatus, there is a horizontal braiding machine in which a lower thread and an upper thread are braided on the surface of a central core member while rotating forward and backward on a circumference. The conventional horizontal braiding apparatus has many problems, such as a lack of braiding speed, intense noise, and many lubrication points.

In order to solve many of these problems, the present inventor studied mainly a power transmission mechanism to a carrier, a structure of the carrier, and a yarn tension control device.
No. 304571 (JP-A-4-185750). This braiding device has a hollow shaft in which the vertical main shaft supplies the core material (A),
A forward rotation shaft that rotates a forward rotation disk with a number of outer yarn bobbins that supply the knitting yarn (B) arranged on the outer periphery, and a reverse rotation that transmits power to a carrier equipped with an inner yarn bobbin that supplies the knitting yarn (C) In a braiding device that consists of a reverse rotation shaft that rotates a disk and the braid (B) braids while moving up and down between carriers, a smooth ring rail surface is formed on the outer periphery of the normal rotation disk, and Power is transmitted to the carrier by contacting the provided rubber roller with the ring rail.

[0004] The proposed braiding device uses a rubber roller to drive the carrier, so that the braiding speed can be increased. The generation of noise in the case of gear transmission is also reduced. This has made it possible to solve conflicting issues such as high speed and low noise. In addition, there are no lubrication points in the carrier drive section, and no countermeasures against dust are required, so that the effect of reducing maintenance is obtained.

[0005]

SUMMARY OF THE INVENTION The present invention relates to
Attempts to increase the braiding speed of the device proposed in 4-185750 and conventional devices of this type, eliminate noise, and solve the problem of product contamination by lubricating the sliding parts. Things.
