SU627431A1 - Device for automatic loading of strip material on spool - Google Patents

Description

The invention relates to film technology, in particular, to the technique of rewinding tape materials, such as films, and can be used in other branches of the national economy where it is necessary to automate the process of loading tape material onto a take-up reel.

A device for automatic charging of films containing a downward guide, provided with an elastic plate, and a movable guide, provided with an elastic curved plate, which communicates with the end of the core of the reel l, is known.

This device does not allow rewinding to a film having a low elasticity of the base material, for example, thin film on a dacron basis. In addition, the film is in constant contact with the guides during winding, which causes damage to its surface.

Closest to the invention, the technical solution is a device for automatic charging of a tape

a material on a reel containing a winding motor, an orientation mechanism, a take-up reel, take-up toothed drum, guide rollers and a guide that is manually inserted between the flanges of the take-up reel so that its end is in close proximity to the core of the take-up reel 2J.

This device does not allow charging of non-perforated film. In addition, the guide is guided to the core of the bobbin manually. This is inconvenient when working with large capacity reels, as well as when working in non-actinic lighting conditions or in complete darkness.

The aim of the invention is to expand the operational capabilities and improve usability.

This goal is achieved by the fact that the device is equipped with an eccentric shaft, one end of which is coupled to the inserted reversible electric motor via a friction and gear train, and one of the guide rollers is freely mounted on the other end and the guide hole made in it is rigidly fixed which pass the optical axis of the photo sensor electrically connected via a time relay to a winding motor electrically connected via an additional time relay to a reversible motor, kin mathematically linked with another guide roller. The drawing shows the kinematic scheme of the device described, ycfpoftcTBo consists of a receiving reel 1, an orientation mechanism 2, a winding motor 3 connected via a time relay 4 to a photosensor 5; the optical axis of which passes through the opening a in the guide 6. The photo sensor 5 consists of a photodetector 7 and a light source 8. The guide 6 is rigidly mounted on an eccentric shaft 9 kinematically connected by means of a gear 10 and a clutch 11 with a reversible electric motor 12 which is electrically connected via an additional relay BpevfeHH 13 to the winding motor 3. On the eccentric shaft 9, a guide roller 14 (rubberized) is freely mounted, and the other guide roller 15 is kinematically connected through a gear gear 10 and clutch 16 with reversible electric motor 12. At the end of guide 6, pressure roller 17 is installed. The device operates as follows. In the initial position, the winding motor 3 is switched off and the receiving reel 1 is set by the orientation mechanism 2 to the predetermined position. When the reversing electric motor 12 is turned on, the eccentric shaft 9 rotates through gear 10 and the clutch 11 in a counterclockwise direction and the guide 6 rises until the pressure roller 17 is pressed into the core 18 of the take-up reel 1, while the guide roller 14 enters in contact with the guide roller 15. At these positions, the guide 6 and the roller 14 are held with a certain force, provided by the friction clutch. At the same time as the electric motor 12 is switched on, the roller 15 starts to rotate through the gear wheel. Gear 10 and clutch 16. When roller 14 is in contact with roller 15, roller 14 also begins to accumulate. The film (not posed) is captured by the rotating rollers 14 and 15, moves along the guide 6 and, having passed through the slot of the core 18 of the bob 1, abuts the inner wall of the core 18. From this moment the film begins to bend upwards, forming a loop. When the film overlaps the opening a in the guide 6, the illumination of the photodetector 7 changes. This serves as a signal for switching on the coiling motor 3 through the time delay 4 with the delay needed to form a loop of the required value. The accumulated amount of the looped film is spent on winding the first turn required to ensure reliable capture of the film by the reel 1. After turning on the winder motor 3 through time relay 13 with the time required for winding the first turn, the direction of rotation of the reverse motor of the electric motor 12 changes. this, the eccentric shaft 9 rotates clockwise, as a result of which the guide 6 is lowered and the roller 14 moves away from the roller 15. At the same time, the clutch 16 and the roles 15, starts to rotate freely, driven Drum-d MSL films. The reversible motor 12 is turned off and the washing process of the motor 3 follows the winding process. Thus, the proposed device allows the automatic charging of perforated and non-perforated films or other tape material into reels of various capacities and under any illumination conditions. Apparatus of the Invention 1. A device for automatically charging a tape material onto a reel comprising a winding motor, an orientation mechanism, a receiving reel of guide rollers, and a guide, which is distinguished by the fact that, in order to enhance operational capabilities and increase usability, it equipped with an eccentric shaft, one end of which is connected with the inserted reversible electric motor through the clutch and gear train, and one of the guide rollers and a rigid fixed guide vypolkevnym therein with an opening through which passes the optical axis of the photosensor, is electrically bonded via time switch with the motor winding electrically connected via an additional time switch with a reversible motor, is kinematically associated with the other guide roller. 316 2.
