SU874795A1 - Pull-away comb of manual warp-knitting machine - Google Patents

Description

t

The invention relates to the field of knitting machine building and can be used in knitwear hauling machines used on household flat panel machines.

. Known manual flat zalna. the machine on which knitwear is pulled using a pull-out comb equipped with spherical heads. The prevention of the spontaneous dumping of the comb dowel from the knit loops is achieved due to the fact that a spindle lock made in the form of a sawtooth lock is worn on the spherical heads of the rods. This is due to the fact that in a known machine, the formation of the first looped row occurs manually by entwining the yarn of the comb pins, while on modern flat-knitting machines, the first looped row is formed automatically by moving the carriage relative to the needle bed. Put the comb on the pins

Knitwear produced on machines with automatic thread laying is impossible, since the rod heads do not pass through the loops formed by the needles.

The purpose of the invention is to prevent the spontaneous dumping of the pulling combs from the loops of the pull-out, knit on the manual flat-knitting

10 machines with automatic thread prokglskry ..

This goal is achieved due to the fact that the detachable comb for a manual flat filling machine containing a bar with hooks attached to it, additionally contains a plate mounted along the bar on the hook side and connected in the vertical plane to

20 strap through the springs. To fix the swivel plate in the initial position, a flat spring is installed on the side opposite the hook side.

FIG. 1 shows a part of the extension comb on an enlarged scale; in fig. 2 - detachment of the comb with fastening of the rotary plate on the horizontal axis, general view; in fig. 3 is a view A of FIG. 2 (plate in operation than position); in fig. 4 - the same (plate in the initial position); in fig. 5 - part of the pull comb on an enlarged scale with the goods wound on it; in fig. 6 - pull the comb with the goods wound on it in the section; in fig. 7 - gre-1 benka pull-out with fastening of the rotary plate with the help of flat springs, general view; in FIG. 8 is a section A-A in FIG. 7 (swivel plate in working position); in fig. 9 shows section A-A in FIG. 7 (swivel plate in rest position); in fig. 10 - side view of the pull-on comb with a lock in the form of limb; in fig. 11 - cut. BB in FIG. ten; in fig. 12 - release of the comb with the retainer in the form of limbs in the section; in fig. 13 is a section B-B in FIG. 12. The comb comb has a strap 1 (Fig. 1) in which the hooks 2 are fastened, the pull-back loops 3 of the knit fabric. In brackets 4 and 5, mounted on the edges of the bar 1 (Fig. 2), axes b and 7 are mounted perpendicular to the rods 8 of hooks 2. On axles 6 and 7 there is a settable swivel plate 9, spring-loaded using coil springs 10 and 11. Plate 9 can occupy two extreme positions - working (Fig. 3) and initial (Fig. 4). At the working position, the plate 9 is pressed against the outer surface of the hooks 2, and in the initial position rests on the bar 1. The upper part of the plate 9 is placed outside the hooks. Due to the fact that the length of the plate 9 is longer than the distance between the extreme hooks 2, and the width more than the distance from the axes b and 7 to the end of the hook, when the plate is set in the working position, it closes all the hooks on bar 1. The plate 9 is fixed in the initial position by means of latches 12 and 13 located on the side of plank 1 opposite to the hooks 2 in this case. The latching function in this case is performed by the lower bent parts of the brackets 4 and 5, which are flat springs. Each of the latches 12 and 13 is equipped with a bend of 14 and 15. In the case of using a pull-over comb of the proposed design, the middle and upper classes equipped with elastic hooks 2, the platinum-9 is made rigid. If the tight comb is used on low-end machines with rigid hooks 2, plate 9 is made of elastic tape. This achieves the elimination of possible gaps between the hooks and the plate, and ensures that the plate is reliably pressed to the hooks. FIG. Figure 7 shows another embodiment of the rotary plate. The pivot plate 16 is connected to the plank 17 by means of flat springs 18-21. At the same time, one end of each flat spring is clamped on the plank 17 and the other on the rotary plate 16. The upper part of the rotary plate 16 is placed under the hooks 2, while the plate 16 can occupy one of two positions: working (Fig. 8), when it is pressed against the inner surface of the hooks 2, and initial (Fig. 9), when it is pressed against the rods m 8. On the flat springs 18 and 21, the curved rods 22 are hingedly mounted designed to move the turntable 16 at the origin Noah position. When using such a construction, the pull-combs on low-class machines, where the hook rods have a significant diameter and have high rigidity, can be used to fix the rotary plate in the initial position, a latch (Fig. 10-13), made on each of two flat plates. springs 23 mounted on the edges of the strap 24. Each of the flat springs 23 (Fig. 11) is equipped with two limbs formed by intersecting planes 24-27 parallel to the rods 28 of the hooks 29. For improved serviceability, the comb is equipped with removable clips 30 (Fig. 5 and 6). Each of the clamps is made in the form of a spring with bent edges, with the height of the clamp 30 being more than half the height of the pull-over comb, and the width of the clamp less than the width of the comb. Such a ratio of sizes makes it possible to reliably fix the knit on the comb. The removal of the accumulated canvas is carried out as follows. Put the release comb with hooks 2 on the knit loops 3 (Fig. 1). . The plate 9 is in this position in the initial position (Fig. 4). Then, using fingers to bend 14 the latches 12 and 15 the latches 13, retract both latches downwards, as a result of which the plate 9 is released and under the action of compressing coil springs 10 and 11 occupies the working position (Fig. 3). In this case, the plate 3 is pressed by its upper part to the outer surfaces of the hooks 2, due to which the hooks are closed and the knitted hinge loops 3 under them cannot go out from under the hooks, which completely eliminates the possibility of spontaneous dumping of the pulling comb. When the product is finished on the machine and the retractor is to be removed, the plate 9 is turned counterclockwise, overcoming the force of the springs 10 and 11. At the end of the turn, the plate 8, acting on the limbs 14 and 15, first pushes the latches 12 and 13 down and then it snaps into place and remains locked in its original position. As a result, the hooks 2 are open and the knit fabric produced can be easily removed from the pull comb. When using a pull comb with a swivel plate placed under the hooks, the pull is produced as follows. Turning the curved rods 22 with their free ends down (Fig. 9), due to the fact that the rods rest against the side surface of the plank 17, the rotary plate 16 is placed in a position where its upper part abuts against the rods 8 of the hooks 2. After that, the released hooks 2 dress on the stitches of knitwear. Then, turning the curved rods 22 with their free ends upwards (Fig. 8), the rotary plate 16 is placed in a position where its upper part is pressed against the inner surface of the hooks 2. As a result, all the hooks are closed and the random release itself becomes impossible. When the comb is fitted, the latches shown in FIG. 10-13; delay is performed as follows. Pressing the flat spring 23 just to the right, overcoming the spring properties of the latch (Fig. 10, 11), moved the rotary plate 16 to its original position when its upper end rested against the rods 28 of the hooks 29. The fixing plate 16 was in this position This is due to the fact that the latch surfaces 24 and 26 are pressed against the rods 28 of the hooks 29. Then they hook the hooks on the knitted hinge loops and, pressing the latch from right to left, put the rotary plate 16 into the working position (Fig. 12), as a result the plate covers the hooks 29 and ie it allows loops to get out from under them. In the manufacture of long products at the back of the machine so that the tricottle being pulled off does not interfere with the maintenance of the machine, it is possible to wind the knit fabric produced on the pulling comb. Fixing the knitted fabric wound on the comb is carried out with the help of removable shirts 30, which are worn on the comb after the tricotics are wound on it. The use of the present invention on manual flat-bed machines makes it possible to completely prevent the spontaneous discharge of the comb from the loops of the knitted fabric. This makes it possible to considerably simplify the maintenance of the machine by reducing the time spent on the suspension of the comb and on the elimination of defects caused by the discharge of the comb. In addition, the danger of the occurrence of injuries to J servicing the car in the zalyshchitsy is eliminated. The use of detachable clips makes it possible to increase the convenience of servicing the machine due to the fact that it is possible to wind the accumulated knit on the comb and fix it securely.
