Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a winding machine configured to actively rotate a chuck for attaching a tube for winding up a sheet-like object or a linear object.

(Prior art and its problems) Generally, when winding up sheet-like materials such as synthetic resin films and paper, or wire-like materials such as synthetic fiber yarn and electric wires, a chuck for attaching the winding tube is used. A winder configured to rotate actively is used.

As such a winding machine, for example, Japanese Patent Application Laid-Open No. 611866
This is described in Publication No. 2, in which a chuck for mounting a winding tube has a pressing piece expanded in the outer circumferential direction by a spring or the like, and tightens by coming into contact with the inner circumferential surface of the tube. By supplying this, the pressing piece is reduced in the axial direction and released from tightening. Further, an electromagnetic clutch for rotational torque control is disposed between the chuck and the driving electric motor so that the material to be wound, such as a sheet-like material, is wound with a constant tension.

A winder with the above configuration requires a pressure fluid supply device to operate the chuck and a power supply device to operate the electromagnetic clutch, and these devices must be installed in a narrow space. Moreover, when a large number of winding machines are installed at narrow intervals, assembly, repair, etc. are extremely difficult.
