(54) Winding drive and winding device incorporating the same


(57) The present invention aims to provide a winding drive capable of easily setting a stopping position of a wound material and further preventing a shift of the set stopping position and a winding device incorporating the winding drive, which needs fewer electric cables communicating in and out of the device.
The winding device (1) mainly consists of a winding drive (2) and a winding drum (21), the winding drive (2) having a main body (40) and a two-core electric cable (23) for electrically connecting the main body (40) and an external DC power source. The electric cable (23) is provided with a polarity selector switch (33), so that a rotational direction of a driving motor (7) is changed by operating the switch (33). The main body (40) is provided with an operation mode selector switch (17) for switching an operation mode, so that the number of rotations of the driving motor (7) detected in a rotation detecting part (25) is memorized in a memorizing part (26) in a stopping position setting mode and the memorized number of rotations is fed back in a normal mode.
