Description

one

This invention relates to the textile industry and can be used in fiber quality control.

Known devices include a spring-loaded removable clip with a vertically movable upper sponge placed in the housing to hold the staples of a given weight.

The purpose of the invention is to mechanize the process of making staples.

For this, the proposed device is equipped with a belt conveyor with a drive mechanism for periodically feeding the fiber ribbon into a removable clamp, a polished plate placed under the conveyor, a spring-loaded clamp for clamping the ribbon between the conveyor and the plate, as well as a camshaft drive and lifting the upper jaw of the removable clamp.

The conveyor drive mechanism for periodically feeding the fibers into a detachable clamp contains a ratchet mounted on the conveyor drive roller, the doggie of which interacts with an abutment fixed to the housing.

FIG. 1 shows the proposed device, plan and section along A-A; in fig. 2 is a section along BB in FIG. one; in fig. 3 is a section along BB in FIG. 2

The proposed device consists of a camshaft 2 placed in the housing 1, which is rotated from the engine or manually by means of the handle 3 through a worm gear

gear 4. On the shaft 2, the cams 5-7 are mounted, and on the side wall of the housing on the axis 8, the link 9 with the slider 10 held by the spring 11, and also the bracket 12 with the roller 13. The slider 10 carries the post 14 where the conveyor 15 is mounted, the tape of which covers the master 16 and the slave 17. Underneath the lower branch of the belt conveyor 15 is a plate 18 smoothly polished from above. The driven roller 17 is loaded

two flat springs P1 19. The tartar branch of the conveyor 15 is clamped to the plate 18 by the clevis 20.

The upper part of the housing 1 is fastened with a horizontal nap tape 21 and installed.

a removable clamp, holding the movable upper jaw 22, which interacts with the vertical stem 23, and the lower fixed jaw 24, is designed to prevent the fibers in the staple from shifting as elastic

strips glued to the base 25 of the clip. The upper sponge 22 presses against the sponge 24 with two springs (strong and weak), and through the stem 23 rotates clockwise relative to the axis 26, squeezing

both springs.

Above the end of the plate 18, facing the jaws 22 and 23 of the detachable clip, there is a clip 27, which is pressed by the action of the spring, 28 of the fiber of the prepared staple to the pile tape 21.

At one end of the drive roller 16, rotating in the slide bearings 29 and 30 mounted on the cross link 31, a handle 32 is installed to move the conveyor 15 manually, and at the other end a ratchet mechanism located in the casing 33.

The conveyor drive mechanism consists of a ratchet 34 mounted on the drive roller and a two-arm lever 35 mounted freely on this roller, on which a spring-loaded dog 36 is fixed. On the inner wall of the casing 33, the counter-dog 37 and spring 38 are fastened.

In the final position of the belt conveyor 15 (leftmost position in the drawing), the lower arm finds the lever 35 on a fixed stop 39 and turns counterclockwise, with the result that the dog with the roller 16 and the ribbon conveyor move by one predetermined step equal to, for example 0.5 mm. Counter-dog 37 prevents the movement of the conveyor in the opposite direction.

Before operation, the device is threaded with a fiber ribbon between the conveyor 15 and the G8 plate, with the end of the ribbon slightly protruding beyond the front edge of the plate.

During one turn of the shaft 2, the following occurs.

The conveyor 15, clamping the front end to the pile tape 21, moves to the final position under the action of the cam 5 on the slider 10. At the end of the conveyor stroke (in the final position), the double-arm lever 35, located on the stop 39, turns the drive roller 16 and the conveyor feeds the ribbon fiber forward by 0.5 mm. In the final position, the cam 6, acting on the roller 13, raises the slide 9, as a result of which the conveyor 15 takes a horizontal position.

This is followed by a return stroke of the conveyor to the extreme right (according to the drawing) of the positiv.

wherein the cam 7 lifts the scraper 23, the upper sponge 22 of the detachable clip rises, and the clip remains open until the front end of the plate 18 is lowered 5 by the pile tape 21. After that, the i23 swivels lower and the clip closes, clamping the edge of the ribbon fed forward by the conveyor. When the reciprocating movement of the conveyor 15 relative to the housing 1 for

0, each stroke of the fiber portion of the pile tape 21 is superimposed on the next portion of the fiber, and a staple is formed. At each conveyor run from the detachable clamp, the fiber layers are smoothed with the clip 27.

5 In the final position, the yoke 27 locates on the anvil 40, rises and does not prevent the next feed of the ribbon of cotton forward by the conveyor 15.

In this way a splice is prepared,

0 the edge of which is clamped between the jaws 22 and 24 of the removable clip.
