(54) DEVICE FOR WRINKING MATERIAL ON THE FRAME AND METHOD OF REPLACING THE FRAME IN THE DEVICE FOR WINDING

one

The invention relates to winding devices, and can be used in the hardware, chemical, textile, cable industry in such processes as obtaining, for example, wire by extrusion or drawing, insulating it or electrochemical processing, drawing metallic or artificial filaments from a melt, etc. d.

A device for winding artificial threads on the frame 1 is known.

The carcass in this device is replaced by removing the empty carcass filled and installed in its place.

A disadvantage of the known device is the inability to receive material at a speed higher than 35-40 m / s due to the sharply increasing breakage of the material. In addition, these devices do not allow the wetting of the material due to the influence of centrifugal forces, which also worsen the conditions for safe servicing of such devices and necessitating the need for static and dynamic balancing of the cages.

MATERIAL

Closest to the invention in its technical essence is a device comprising a fixed frame and a material stacker mounted rotatably about the axis of the frame 2.

The frame in this device is replaced by a method in which the stacker is removed from the transport path for the time that the empty frame is used for removal and installation in its place.

A disadvantage of the known device is the fact that it lacks the possibility of uniform and fast stacking of the material over the entire width of the frame.

The aim of the invention is to increase productivity.

ts

The goal is achieved by the fact that the known device is equipped with a mechanism for rotating the stacker with the drive and the reciprocating mechanism of the stacker with the drive.

The handler is made in the form of two shoulders.

20 levers with the ratio of the respective shoulders to the width and the winding radius of at least one.

The shoulders of the two-arm stacker arm can be articulated with the output axis of the rotation mechanism and with each other by means of spring-loaded hinges.

The method of replacing the frame in the device for winding material is characterized in that the removal of the used frame and the release of the path of movement is carried out by aligning the stacker arms with the axis of its rotation, and the frames are moved parallel to the axis of rotation of the stacker until its shoulders fully exit from the mounting holes of the frames.

FIG. 1 shows a diagram of the device; in fig. 2 shows a possible arrangement of the mechanisms of rotation of the stacker and its reciprocating movement.

The end of filamentous material 1 passes through the treatment zone 2 and the feed drive 3, is passed through the rollers 4 of the stacker 5 and is fixed on the fixed frame 6. The frame 6 is mounted on the base 7 and fixed on its landing lug by a nut 8. The stacker 5 is made in the form of a two-armed lever , has the ratio of the corresponding shoulders to the width and final radius of the winding (to the geometric dimensions of the frame) not less than one and is articulated with the output axis 9 of the rotation mechanism 10 by means of a screw-nut system 11 and a spring-loaded joint 12, its shoulders are articulated Another similar spring-loaded hinge 13. The mechanism 10 rotating the stacker 5 is mounted on the moving part of the mechanism 14, reciprocating movement to provide a layout material 1 over the entire length of the frame. Mechanisms 10 and 14 have individual drives.

The device works as follows.

When the feed drive 3 and mechanisms 10 and 14 are turned on and the reciprocating shifting material 1 enters its reception area, the stacker 5 rotates around the frame 6, successively, turn by turn, wraps the frame 6 with it. At the same time, the mechanism 14 spreads the resulting turns over the entire width of the frame 6 in increments determined by the speed of movement of its moving part.

Replacing the wound frame 6 with an empty one is carried out as follows. The framework body moves free from the stacker 5, for which its arms are turned around the hinges 12 and 13 to a position where their longitudinal axes coincide with the direction of the output axis of the rotation mechanism (in principle, it is enough to turn the arms so that they are in space limited frames with the surface of their inner bore hole), unscrew the nut 8, move the filled frame parallel to the axis of rotation of the stacker 5 to the full exit of the stacker arms from the bore hole of the frame , an empty frame is installed on the vacant space by a similar movement, fixed with a nut 8 on the landing projection of the base 7, and the stacker's shoulders are turned in the opposite direction to take up their initial position under the action of the elastic elements of the spring-loaded hinges 12 and 13 (the hinges can then be pinned ). The introduction of the invention into the people's economy allows:

winding the filamentous material on coils, frames, drums and other mandrels in a quantity that is practically limited only by the conditions of its subsequent continuous winding in the consuming apparatuses;

improve the quality (density) of the winding

material;

remove restrictions on receiving speed, which leads to an increase in productivity of the thread-processing aggregates;

significantly reduce the operating costs of servicing such units, since there is no need for static and dynamic balancing of the frames, and consequently, in balancing machines, highly qualified personnel for balancing, this also increases the service life of receiving devices and reduces energy consumption, since there is no need to rotate heavy frames with reel material (tens, hundreds, and in some cases, thousands of kilograms).

5 substantially improve working conditions

attendants;

dramatically reduce the likelihood of accidents and injuries, especially at high reception rates

and material, since the fixed frame is not subject to the influence of destructive centrifugal forces, inevitable when it rotates.
