Description

one

The invention relates to instrumentation and can be used in film technology and other fields of technology for winding tape material into rolls on reels.

The purpose of the invention is to reduce power consumption when reversing by reducing the applied torque.

FIG. 1 shows the proposed drive, a general view; in fig. 2 shows section A-A in FIG. one.

A piezoceramic oscillator 1 is located on the stator 2, in bearings (not shown) of which shaft 3 is installed with a reel 4 installed on it for a filmstrip (not shown). The shaft 3 is connected to the rotor 5; Elastic pushers 6 supported on the surface of the oscillator 1 are supported on the surface of the friction interaction of the VIA. Near the pushers 6, on the side opposite to the direction of rotation, there are stops 7 on the ring 8 connected to the directional movement switch of the film.

When applied to the oscillator 1 of the excitation voltage, it causes mechanical oscillations in the elastic pushrod

l x 6, which transfer energy to the rotor 5, drive it into rotation and through the shaft 3 to the reel A with a film.

If a torque is applied to the reel 4 with the film, consequently, the shaft 3 and the rotor 5 opposite to the direction of motion of the film, then the pushers 6 carried by the rotor 5 move to the stops 7. After that, the rotor 5 closes with the ring 8. As the ring 8 is connected with the switch 9 and is fixed motionless relative to the stator 2, it is impossible to turn the reel 4 with the film in the opposite direction.

If the switch 9, and consequently, the ring 8 is rotated along the direction of motion of the film, the stops 7, the bend pushers 6, will lead them out of engagement with the rotor 5. At the same time, the rotor 5 can be freely rotated and the reel 4 connected to it any direction. In this way, the reversal of the film, charging and discharging it is ensured without failing the coiler.
