SU140756A1 - A device for removing yarn residues from spools of weaving machines - Google Patents

Description

Devices are known for removing yarn residues from spool weaving machines, including a housing with a boot loader, two pairs of displaced, genuinely spring-loaded sponges cooperating with the yarn, a pusher of a spool head, a drive of a pusher and a jaw.

The effectiveness of these devices when removing the fillings of the spinning skein and overlap is very low, which in some cases leads to the necessity of applying manual labor in this operation. In addition, the design of a number of these devices is such that spools spoil during the removal of yarn residues.

The proposed machine is designed to clean the weft spools from all yarn residues and improves the reliability of work when the spinning reels and overlaps are removed from the spools, which distinguishes it from known devices. This is achieved by supplying the pusher at its working end with a twist tip that interacts with the spool head. The tip is then placed in the pusher cavities.

To prevent spoilage of the front-pair sponge spools, they can be made with notches along the smallest bore spools diameter and provided with a groove-like bevel in the rear part.

Fixing the spools in length, removing the down and pulling the threads of the removable residue can be achieved by making the sponges of the back pair interacting with the bottom ring of the spool spool when it is loaded into a mashine and positioned across the sponges of the front pair, and the sponges of the back pair can be equipped with polyvinyl chloride inserts .

FIG. 1 shows a general view of the proposed machine; in fig. 2- mechanism for removing residual yarn, in plan; in fig. 3, 4 and 5 - successive stages of the machine operation when removing yarn residues; neither FIG. 6 and 7 shows the interaction of the front pair of jaws with the remainder of the yarn.

No. 140756-2 L1ashina for cleaning the weft spools of all types of yarn residues includes a body / with a charging box 2, two pairs of spring-loaded sponges 3 and 4 displaced along the length (Fig. 2), a pusher 5 of the spool head 6 and a drive 7 of the pusher and sponges . The pusher 5 (Figs. 3, 4, 5) at the working end is provided with a spring-loaded tip 8, which is placed inside it. The front pair sponges 3 (FIGS. 6 and 7) are made (FIGS. 6, 7) with recesses 9 along the smallest diameter of the lot spools and are provided in the back with a grooved bevel 10. The rear sponges 4 are located across the front pair sponges 3 and are provided with polychlorinated inserts 11 (fig. 4) of light color.

Cleaning weft spools of all types of yarn residues is carried out in the proposed machine as follows.

The spool 6 from the charging box 2 goes to the jaws 3 and 4, while the jaws 3 of the front pair are automatically divorced by the cams -12 in order to get this spool between them. The sponges 4 of the rear pair interact at this moment of refilling the spool with its lower ring 13, ensuring the centering of the shank 6 along its length. Before interacting with the pusher 5, the front end of the shunt 6 is centered along the axis of the latter by a folding fork 14 (Fig. 3) and an action.the separator 15 providing loading of the loaded P1 puli with the weight of the overlying shucks in the chuck 2.

The position of the machine parts after the completion of the spool filling is shown in FIG. 3

Next, the pusher 5 receives the movement to the spool, and the cams 12 will allow the springs 16 to bring the front pair jaws 3 to the slider 6 without damaging its surface. At the same time, the spreader 15 is retracted from the path of the pusher 5. As the further movement of the pusher 5 firstly occurs, the spring-loaded tip 8 comes in contact with the pull-off head, and then, when the spring 17 of the tip 8 is slightly compressed, the bobbin moves together with the pushrod 5.

During this period of movement (Fig. 4), the spreader 6 sponge 3 of the anterior pair detains the remainder of the yarn and, due to the force of this interaction, is wedged in its guides. GoLovka same spool 6 wedges a pair of 4 rear jaws. Since the spring 77 of the tip 8 was preloaded at the initial moment, the potential energy accumulated in it allows the tip 8 to overcome the forces of friction of yarn residues on the spool, which periodically inhibit the movement of the pinch 6.

At the end of its movement, the bobbin 6 is finally cleared of yarn residues, and the removal of lint and tangible threads of the removable residue is made with inserts 11. The cleaned shank O (Fig. 5) is discharged into the special container under the action of the unclamping spring 17, and The removed sleeve 18 yarn drops from the tip 8 (when it is withdrawn to its original position) into the tray and is removed further from the machine.

In conclusion, VNIPLTEKMASH notes the usefulness of the proposed machine, an experimental sample of which has passed production tests with positive results.

Subject invention

T Maschina for cleaning-weft spools of all types of yarn residues, comprising a housing with a boot holder, two pairs of displaced along the length of spring-loaded sponges interacting with the yarn, a pusher of the head, a drive of the pusher and sponges, characterized in that the purpose of increasing the reliability of work when removing the spinning skein and overlap fillings from the spools, the pusher on the working end

it is equipped with a spring-loaded nakohechnip in its cavity, interacting with the spool head.

2. The machine according to claim I, from l and h and y w, and with those m. that, to prevent damage to the spool spools, the front pair sponges are made with notches along the smallest diameter of the lot spools and are provided with a grooved bevel in the rear part.

3. The machine according to claim 1, is different in that for fixing the spools in length and removing the fluff and yarns of the rear broom sponge, the spool seats cooperating with the bottom ring are located across the front pair of sponges and are provided with PVC sleeves.
