Then, control portion 40 sends control signals to not shown relay etc. and makes motor 23a be energized.Thus, reverse roll 22 starts to rotate, and is in the package P with this reverse roll 22 contact condition and also begins to rotate.
It is then used by Fig. 9 B to illustrate to make reverse roll 22 leave the action form when package P.
Control portion 40 sends control signals to not shown relay etc. and cuts off the power supply of motor 23a.Thus, reverse roll 22 stops the rotation, and the package P being in contact condition with this reverse roll 22 also stops the rotation.
Then, control portion 40 sends control signals to not shown electromagnetic valve etc. and supplies the air to cylinder 23da.Thus, piston 23db slides, and is arranged on piston rod 23dc on this piston 23db and moves along direction out in cylinder 23da.Air actuator 23d makes the bar 23e being arranged on piston rod 23dc rotate.
Bar 23e makes sub-arm 23c rotate centered by axle SH2 to rotate, and makes arm 23b rotate centered by axle SH1 to rotate simultaneously.Illustrate for, owing to sub-arm 23c is to rotate rotatably mounted centered by axle SH2 being installed with, therefore rotate with the rotation of bar 23e.Due to arm 23b together with sub-arm 23c to rotate rotatably mounted centered by axle SH1 being installed with, therefore rotate with the rotation of bar 23e.So, drive division 23 makes reverse roll 22 move, it is possible to make this reverse roll 22 leave from package P.
So, the drive division 23 of this embodiment uses air actuator 23d to make reverse roll 22 move.Thus, spinning machine 100 can control period of making reverse roll 22 leave package P accurately.Accordingly, because this package P can be made after making reverse roll 22 leave package P immediately to contact with driving roller 61, therefore package P is unlikely to unintentionally reverse.Thereby, it is possible to prevent spinning Y from relaxing.
Further, even if also be able to the difference reducing reverse roll 22 with the contact pressure of package P when the external diameter of package P is different.Thereby, it is possible to prevent the deterioration of the spinning Y deforming or being wound up on package P of package P.
