Description

The invention relates to the field of textile industry, and more specifically to the manufacture of carpets.

Since ancient times, hand-woven carpets have been known, knitting in which they are made with single, one-and-a-half and double knots.

The disadvantages of manual carpet weaving are their complexity, very low productivity. A rug of 2 × 3 m in size is made all over the world depending on the density from 2 months to 2-3 years. The density of the carpet over the entire area is not the same; sometimes the symmetry of the ornament and the accuracy of observing the corners are violated.

No analogues of this invention were found.

The aim of the present invention is to eliminate the above disadvantages and to create a device that allows you to make carpets with a double knit according to the technology of hand weaving.

The goal is achieved by the present invention with a double knotting automated device consisting of the following nodes and parts: node 1 includes a pusher and a shuttle; the node 2 includes a catcher of thread, a rammer of thread with a fixed cutter attached to it; the node 3 includes the blades of the pusher of the catcher of the ends of the thread, the pusher-shuttle, two front guides, two rear guides, a latch; the node 4 includes a springy plate, pressing the trap thread; the node 5 includes a movable thread cutter, mounted in a special socket, a shock-absorbing spring working on compression; the node 6 includes a filler of threads - a collet mounted on an oval disk, a cam, a compression spring, two adjusting bolts with a spring working in tension, a rubber ring for compressing and unclenching the fingers of the collet, an opening for a rod that controls the density of the carpet; working as follows: the first pair (carpet yarn captors) passes between the two carpet yarn threads, opens its plates to capture the ends of the carpet yarn, which the second pair of plates (carpet yarn traps) brings, clutching the two carpet webs through which the first a pair of plates captures the ends of the carpet yarn and when the piston moves back it returns to its original position, in which a double carpet knot is formed.

To ensure this task, this device and its parts, made in the drawings in orthogonal projections, are proposed. In FIG. 1 shows a drawing of the pusher - 1 and the housing - 2, acting as a shuttle.

Further, drawings with serial numbers of figures shown with an alternate set of parts. In FIG. 2 shows a drawing of a catcher of a thread - 3, a rammer of a thread - 4 with a fixed cut-off attached to it - 5. In FIG. 3 shows the shovels of the catcher of the ends of the threads - 6, the pusher-shuttle - 7, its front two guides - 8, the two rear guides - 9. The latch - 10 in the groove - 11 provides stability to the translator-shuttle - 7, in FIG. 3.

In FIG. 4 presents a springy plate - 12.

In FIG. 5 shows a movable thread cutter - 13.

In FIG. 6 presents the feeder of the collets - 14.

In FIG. 7 is an assembly drawing of a carpet double knot knitting automated device.

Double knitting is carried out as follows: the pusher - 1, strung on the shuttle case - 2 (Fig. 1), first pushes the shovels of the catcher of the ends of the threads - 6 (Fig. 3). The pusher-shuttle - 7 (Fig. 3) is fixed by a spring - 15 with the pusher - 1 (Fig. 1). Then, passing between the two warps of the carpet, the shovels of the catcher of the ends of the threads - 6 (Fig. 3) are opened by the front guides - 8 (Fig. 3). Then the trap of the threads - 3 and the rammer of the threads - 4, which are also fixed by the springs 16 and 17 with the pusher - 1, respectively, move (Fig. 2). The thread catcher - 3, moving and approaching the hole - 18, catches the thread, feed - 14 thread, captures it with a flexible presser - 19. Behind the catcher of threads - 3 moves the rammer - 4 and, rubbing it with its stationary cutter - 5 with a movable cutter - 13, cuts the knotted carpet thread. The yarn catcher - 3 and the yarn finisher - 4, moving around the two carpet yarn yarn carpet (yarn yarn on the drawings are not shown), in the middle of which they are waiting in the open form of the spade of the catcher of the ends of the yarn - 6.

When moving back the pusher - 1 (Fig. 1) the pusher-shuttle - 7 moves back. Two rear guides - 9 (Fig. 3) provide the shovels of the catcher of the ends of the threads - 6 capture of the ends of the nodal thread and the departure back. This forms a double carpet knot.

When the pusher - 1 (Fig. 1) moves away with the sleeve - 20 (Fig. 1), the door - 21 (Figs. 1 and 6), resting against the cam - 22 (Fig. 6), opens. The door - 21, passing in the open form behind the cam, returns to its previous state due to the springy plate - 24 (Fig. 6). Spring plate - 24 is not shown in other drawings.

When moving the sleeve - 20 (Fig. 1) forward, the door - 21 (Fig. 1 and 6) is in the closed position. This position provides him with a springy plate - 24 (Fig. 6). The door, moving in closed form, presses the cam - 22 (Fig. 6), in which the collet - 14 clamps the knotted thread threaded into the hole - 25 (Fig. 6), and feeds the hole - 18 to the window (Fig. 1). The catcher of the thread - 3, going to the window of the hole - 18, to which the nodal thread has already been fed, takes it. Following the catcher of the thread - 3 moves the rammer of the thread - 4, on which the fixed cutter of the thread - 5 is rigidly fixed (Fig. 2).

In FIG. No. 4 presents a springy plate - 12. When moving, it ensures that the catcher of threads - 3 is pressed against the hole - 18, in which there is already a thread fed by a collet - 14.

In FIG. 3 is a drawing of a device for a movable thread cutter. This device is located in slot 28 in FIG. 1. His drawing is made on an enlarged scale, it is also not shown in other drawings, including the assembly one.

In FIG. 1 and other drawings show a hole - 29. It serves for a rod that has a different thickness (the rod itself is not shown in the drawing) and is selected depending on the density of the carpet.

In FIG. 2 shows the socket - 30. The collet mechanism of figure 6 is located in it. Its drawing is made on an enlarged scale. In FIG. 1 shows the hole - 31. This hole is used to secure and adjust the spring plate. In FIG. Figure 6 shows the collet mechanism - 14, with the cam - 22. The collet - 14 has three clamping fingers. On the bend of the upper part of the fingers, a rubber ring is put on - 32. This ring allows you to compress and unclench the collet - 14. The cam - 22 rests on the spring - 33, which works as a compressor. In FIG. 6 shows an oval disk - 34, on which a collet - 14 is attached.

The oval disk is movable and is regulated by the distance from the hole - 18. This adjustment is provided with two bolts - 35 and spring - 36, working in tension (Fig. 6).

In FIG. 5 shows a movable shut-off device - 13. Depreciation of the cut-off device is provided by a spring - 37, operating in compression.

An assembly drawing of a carpet double knot automated knitting device is shown in FIG. 7.

The design of the knitting device mainly consists of two paired plates. The first pair, passing between two rugs of the carpet, opens the plates and waits for the second. The second pair of plates, carrying with them a cut piece of carpet yarn, clutching two rugs of the carpet, passes between them. Then the first pair picks up the ends of the carpet yarn and when the piston moves back, it returns to its original position, in which a double carpet knot is formed. To accomplish this task, this device must be tied to pistons having translationally returning movements.

Having connected the knitting device to the pistons providing translational movements, and to the computer program, we get an automated double carpet knitting device that allows you to make carpets using manual weaving technology. Depending on the type of pistons used, it is possible to produce a 2 × 3 carpet in 9-10 hours. Depending on the cross-section of the warp, knitting and weft yarns, it is possible to achieve a carpet density with a double knot of up to 200 × 200 or more in 1 dm ² against, for example, traditional Dagestan carpets 45 × 45 knots per square meter. dm.

With manual carpet weaving, when the carpet cloth is woven on the machine, you have to stop the process and relax the shafts at a certain height, lower the woven part of the carpet to the lower shaft, then stretch the warp again and continue working. When installing the proposed device on the machine, you do not have to relax the machine shafts, therefore, the tension of the warp remains constant, which ensures the same density over the entire area of the carpet, symmetry of the ornament and geometric rigidity of right angles.

High density, double knot, strict symmetry of the ornament, the rigidity of the right angles of the carpet - these are indicators of the highest quality of carpets that a carpet machine is capable of manufacturing, on which the device is installed carpet double knot knitting automated, consisting of the following nodes and parts: node 1 includes a pusher and shuttle case ; the node 2 includes a catcher of thread, a rammer of thread with a fixed cutter attached to it; the node 3 includes the blades of the pusher of the catcher of the ends of the thread, the pusher-shuttle, two front guides, two rear guides, a latch; the node 4 includes a springy plate, pressing the trap thread; the node 5 includes a movable thread cutter, mounted in a special socket, a shock-absorbing spring working on compression; the node 6 includes a filler of threads - a collet mounted on an oval disk, a cam, a compression spring, two adjusting bolts with a spring working in tension, a rubber ring for compressing and unclenching the fingers of the collet, a hole for the rod regulating the density of the carpet; working as follows: the first pair (carpet yarn grabbers) passes between the two carpet yarn threads, opens its plates to capture the ends of the carpet yarn, which the second pair of plates (carpet yarn traps) brings, grabbing the two carpet webs through which the first a pair of plates captures the ends of the carpet yarn and when the piston moves back it returns to its original position, in which a double carpet knot is formed.
