Claims

[Scope of utility model registration request]

A take-up roll is connected to an output shaft of a slip clutch, and the take-up roll is rotated by the output shaft of the slip clutch, and a web such as paper or film is guided to the take-up roll via a feed roller, and the slip Rotate the input shaft of the clutch at a higher rotation speed than its output shaft,
In the winding machine, the slip clutch applies torque to the take-up roll to create tension in the web between the feed roller and the take-up roll, and tightly winds the web onto the take-up roll. An input shaft of the take-up roll is connected to an output shaft of a continuously variable transmission, an input shaft of the transmission is connected to a driving motor, a gear ratio adjustment shaft of the transmission is connected to a pilot motor, and an input shaft of the take-up roll is connected to an output shaft of a continuously variable transmission. A winding diameter detection means for detecting the winding diameter and a rotation speed detection means for detecting the rotation speed of the feed roller are connected to an arithmetic circuit, the arithmetic circuit is connected to the pilot motor, and the input shaft of the slip clutch is substantially connected to the arithmetic circuit. In order to maintain a uniform difference in the rotational speed of the output shaft, the calculation circuit calculates the appropriate rotational speed of the input shaft of the slip clutch from the winding diameter of the take-up roll and the rotational speed of the feed roller, and rotation speed detection means for rotating a gear ratio adjustment shaft of the transmission by a pilot motor, and further detecting the rotation speed of the input shaft of the slip clutch; A take-up roll drive device characterized by being provided with a feedback control mechanism that performs feedback control.
