SU97118A1 - Device for cross winding a ribbon or roving on cartridges - Google Patents

Description

Machines for cross-winding a ribbon or a rove for cartridges with automatic replacement of the latter, having a winding roller, a carrier, guides for the axles of the rollers with cartridges and a lever that interacts with the axles of the roller for the cartridges and associated with the cartridge cutter are known.

The proposed device in comparison with the known improves the winding of the tape or roving on the cartridges.

The peculiarity of the proposed device is that the lever which controls the cutter is double, one part of which, provided with grooves, serves as a guide for the axles of the cartridge roller with an accumulated bobbin, and the second covers the lower end of this guide and moves relative to the first part of the newly developed reels.

To receive the next cartridge and feed it under the action of weight along the inclined guides and the winding roller, a spring-loaded arcuate lever is used.

Fig, 1 shows a schematic view of the device sock at the beginning of the operation of the reel; in fig. 2 - at the end of the production time of the reel and at the time of the filing of the next cartridge; in FIG. 3, at the moment of the end of the production of the previous reel and the beginning of the development of the next; in fig. 4 - at the time of removal of the accumulated reel; in fig. 5 - the device of the winding roller and cartridge.

The wooden natron, mounted on the roller 2, is pressed by its own weight against the winding roller 3.

The roller 2 rotates at the start of winding the bristles 4 mounted on it, which meshes with the bristles 5j mounted on the winding roller 3. As the diameter increases, the C and 5 races of the bobs are: Epc yc and the roller 2 rotates further due to friction forces the surface of the reel on the surface of the winding roller 5.

The cartridge 1 is provided with a needle 6 for clamping the end of the strap or roving at the beginning of winding.

Before winding, the cartridges are located in the magazine 7, which has grooves in which the pins of the roller 2 are moved as it passes through the magazine

under the action of its own weight, in fact the emphasis 8 cutter 9.

Drove 10 reel type moves the tape or roving back and forth along the generatrix of the winding roller 5.

In the process of winding the reel pin roller 2 moves through the grooves

11 shop and press the lever, which consists of two parts 12 and 13, hinged on one finger 14. Part 13 of the lever has a flap 15, which covers at the beginning of the winding groove part 12. The rotary lever, consisting of parts

12 and 13, controls the cutter 9. At the exit of the cartridges / from the magazine 7, a spring-loaded arcuate lever 16 is installed, which serves to receive the next cartridge and lower it to the winding roller 3.

The tape coming from the outlet cylinder of the belt machine is fed by the carrier 10 to the cartridge 1. During the cross sectional winding of the ribbon on the cartridge and increasing the diameter of the reel, the cartridge with roller 2 moves along the grooves // and, pressing its pins on the lever consisting of Parts 12 and 13, raises it up.

When the diameter of a given size is reached by the reel, the lever takes the position indicated in FIG. 2. In this case, the lower stop 17 of the trimmer 9, which is pivotally connected to the part 12 of the pivot arm, deflects and releases the next cartridge 1, and the upper stop 8 blocks the way to the other cartridges.

Freed from the arcuate lever, the / 5 cartridge smoothly lowers onto the winding roller 5, and the lever / & returns the spring 18 to its original position.

At this moment, the roller 2 (with an unworked bobbin) passes with its pins into the grooves of the lever part 12 and the bobbin, rolling on the winding roller 3, takes the position shown in FIG. 3. In this position, the bobbin continues to rotate and wind the tape or roving on itself until the carrier 10 drives the ribbon or rove under the needle 6 of the newly fed cartridge and starts winding on the next cartridge.

The new reel, moving as it is winding up, squeezes the pins of the roller 2 with the accumulated reel over the protrusion 19 and lifts the lever part 13, which, when moved, opens the recess 15 of the lever part 12 and the reel drops onto the conveyor or other receiving device for the finished reels.

When the lever part 13 is further raised, the protrusion 19 extends beyond the groove line 20 and the lever part 13 moves down to its original position under the action of its own weight.
