The present invention relates to a drive device for an indirect winding cloth roller in a loom. In general, the method of winding the knitted woven fabric on a cloth roller includes a so-called direct winding method of winding by rolling the support roller on the cloth roller, and the cloth roller by rotating it. There is a so-called indirect winding method.

In the latter indirect winding, a flaw occurs and the cloth roller is actively reversed when the winder denses, so when the winding diameter is large, the amount of the winde dense increases even in the same rotation, and the excess fabric is sag. have. In this case, it is conceivable to configure the cloth roller so that the cloth roller is not rotated at the time of reversal by installing a one way clutch between the supply rollers, but there is no resistance to the cloth roller reversed by the tension of the woven fabric. It was not possible to eliminate the defect of excessive rotation of the back or the amount of the wind mill of the woven fabric.

Conventionally, in order to solve such a defect, a driving mechanism of the cloth roller was used to control the transfer of the reversal by using a ratchet mechanism on the cloth roller shaft. However, the structure is complicated to install the ratchet and brake for the reverse stop on the cloth roller. As a result, manufacturing and assembly are not only cumbersome, but technical problems such as wear of parts remain.

The object of the present invention is to support the sprocket wheel by means of the one-way clutch, etc., which transmits the motion only in the forward rotation with respect to the surface roller, and is caught in the sprocket and the sprocket wheel of the cloth roller shaft. It is equipped with the movement transmission means such as the tension sprocket wheel of the chain and the one-way clutch which acts only when the shaft of the sprocket is reversed, and a toll limiter is interposed between the driving shaft of the cloth roller and the sprocket. Provides a drive device for indirect winding cloth rollers in looms that can prevent excessive wind accumulation of woven fabrics at the time of reverse reversal of wind mills, etc., and at the same time, simplify the structure and easily manufacture and assemble. It is.
