困難であるという問題があった。(Prior art and its problems) Generally, a driving roller, a traverse roller, or the like installed in a textile machine such as a spinning machine or a false twisting machine is
It is necessary to temporarily stop the rotation of the roller for the yarn splicing operation or the doffing operation. Therefore, as the roller device, for example, one having a structure as described in JP-B-61-36091 is used. That is, in this device, a driving shaft is arranged in parallel with a shaft to which a plurality of rollers are fixed, and the rotation of the driving shaft is mounted on the roller by a gear or a driving mechanism such as a toothed pulley and a toothed belt. The rotation of each roller is transmitted to the shaft, and the rotation of the drive shaft is stopped by the clutch incorporated in the drive mechanism so that the rotation of the drive shaft is not transmitted to the roller mounting shaft. With such a structure, a driving shaft and a driving mechanism are required in addition to the roller mounting shaft, and a space for installing those components is required, which increases the size of the entire textile machine. There was a problem. In a roller device as disclosed in Japanese Utility Model Laid-Open No. 58-78850, a plurality of rollers are rotatably mounted on a drive shaft, and each roller is integrated with the drive shaft via a friction clutch. It is configured such that the rollers are connected to rotate the roller, and the operating piece is brought into contact with the clutch or the roller peripheral surface to stop the rotation of the roller. Therefore, an operating mechanism for stopping rotation must be installed outside the clutch,
There was a problem that it was extremely difficult to assemble and maintain the work in a narrow machine base.

When the stator 10a of the electromagnetic clutch 10 is energized based on a signal from a control device (not shown), magnetic flux is generated to magnetize the stator 10a, and the magnetic flux causes the rotor 10b to rotate. The amateur 10c is magnetized and attracted, and the amateur 10c is brought into close contact with the rotor 10b. Therefore, the roller 7 is rotated together with the shaft 1. If a yarn breakage occurs during winding and a yarn splicing operation is performed, or if a preset yarn is wound and a doffing operation is performed, a roller stop signal from a control device (not shown) 10a of the electromagnetic clutch 10 based on
Is turned off. Then, the magnetic flux of the stator 10a disappears, and the armature 10c is separated from the rotor 10b by a spring or the like built in the armature 10c. Therefore, the roller 7 can freely rotate with respect to the shaft 1, and since the roller 7 is in contact with the nip roller, the winding package, or the like, the roller 7 stops at that position due to the rotation resistance of the roller or the package.
