Description

A kepodvi weaving loom is offered; shuttle boxes fortified separately from the batan, with fixed gear and movable rowing are used as a bard for nailing a duck, iiK (dj; dpoe hingedly fixed on either a batted blade or on a Gall chain that bends around two fixed stars and one feat; 11th, from which the reed receives movement. To deflect the teeth of the comb-like bird at the moment of flight, the shuttle is lowered and to lift the nxi / cS, the aim is to pick up the eyeball, and a spring-loaded guide and roller, rolling alternately from the top and bottom to the right. L moiety associated draft type with a reed. When varianate Gall chain for -.to. serves the same purpose upor.i

To drop the shuttle, there is a shuttle box in the form of a cylinder, 3 which enters races, consisting of an elastic air pumped by air: an epigram, having an elastic booster spliced with it, Hbiii i, an elastic firing pin located inside another rigid chamber, moving inside the shuttle box,

In the schematic drawing of FIG. 1, a front view of a weaving machine with a device for nailing a weft; FIG. 2 is a side view of the same machine in section along the line 1J7 of FIG. one; FIG. 3 view

his top; FIG. 4 is a cross section of a cylindrical shuttle box along the line of FIG. 3; FIG. 5 is a cross section of the race of the same box along the line Cr of FIG. 3; FIG. b - cross section of the same box along the line de fig. 3; FIG. 7 - view of the lower ends of curved hooks for ordinary shuttles; FIG. 8 - modification of the surge device to replace the batan blade.

Curved plates and a hook 4, which form a comb-like tail for the shuttle, are clamped between the loosely fortified plg lines 3 of the weaving loom with fixed shuttle boxes (Fig. 1 and 2). The lower ends of the hooks are curved according to the shape of the lower part of ordinary or cylindrical shuttles (Fig. 7 and 2).

The main threads "j," 2, and so on (Fig. 3) are passed between the plates with hooks 4, with those of them being lowered downwards, passing at the bottom of the trellis bow, but never going out their own gaps for each thread, although the ends of the plates 4 are not interconnected. Between the ends there are free prozory, Batanna blade 8 (as in conventional machines with a lower battle) swings around the hinge 6, driven

in the movement of the connecting rod 7 from the main crankshaft shaft or other known method (Fig. 2). The upper part 8a is mounted on two spring-loaded hinges 86, which can only bend in one direction and a stop acts on the other side. The springs of these hinges 86 always tend to straighten the top of the batan, as shown in position 1 (Fig. 2). In the upper part of the blade 8a there are clamped lamellar teeth with free ends, forming a comb-like reed 9 (Fig. 1 and 2). The ends of the teeth are bent i forward slightly and can penetrate between the threads (1, 2, etc.) of the base so that the latter lie with the teeth of the reed, which make the surf of the padded weft. In order that, when entering into the basis, the ends of the teeth of the Byrd 9 not to be hooked onto the threads and not disrupted them, these wedge-flattened, nullified and rounded. After some work, the ends of the teeth continue to grind more and more. It is possible to take a step between these teeth either exactly or equal to, or a multiple step, between the scleosal teeth. In order to create a pitch between the warp threads equal to the pitch of the teeth, it is possible to slightly pull back all the warp threads with sharply hooks away from the straight line. Due to the fracture of the line, all the threads will adjoin the teeth of m from the same side and will give a pitch that is the same with the steps of the scissors.

If you follow the sequence of operations during one revolution of the crankshaft, starting from the moment of the last drive, you will notice that before the end of the drive roller 15 rolls from the top of the guide 12. After the surf is completed with the ridge-shaped bird 9, the duck driven by the action of the spring 14, swings out from under the roller 15, is pumped out around the hinge 13. After) about 9 spring-loaded guide 12 yVVetts up to its extreme position, and during the whole time of the return stroke of the baton roller 15, is pressed, rolls under | guide 12 (figs. 1 and 2). The duration of the change of the throat and the movement of the shafts may be left the same; as with conventional machines. The roller 15. under the guide 12 rolls down along the cutter 15a.

a batane blade 8 and with the help of a gig 16 tilts forward the top of the batan. This continues until the left position of the P and III batane and crank (Fig. 2).

In this case, the tooth of the Byrd 9, leaning in the direction of the breast, emerges from under the base, as shown in position il (Fig. 2). In the latter, the roller 15 is released from under the guide 12, and the top of the batan, due to the release of the rod 16 and the spring hinges 8o, is straightened; at the same time, the roller 15 rises and is positioned above the guide 12. In such a straightened position, the reed teeth, returning backwards, do not cling to the padded weft. They pass under him and behind him to the rear dead position IV and return to position III. The shuttle can be started immediately after the change of shims, i.e. from position II, and lasts to the lower position III of the crank, when the straightened batan tippers Byrd 9 approaches the duck from behind. Upon further movement, the tooth of the bird 9, climbing along the arc of the circle of the batan, thanks to the bent ends, captures the ducks, leads him forward and finally nails him to the worked fabric (Fig. 2). The roller 15 in the forward course of the batane goes all the time over the guide 12. After that, all operations are repeated in the same order. All other parts of the loom can be of any known type, and the described device can be applied or attached to each of them. Difficulty can be encountered only at machine tools intended for fabrics with very thick and thin warp threads, as this increases the possibility of hooking with the reed teeth to the base.

In order to paralyze this difficulty and at the same time prevent breakage of the warp threads, the upper part of the blade 8a with the reed is made on a spring hinge 8 (Fig. 2). In the case of engagement, the frame, not releasing the weft, is deflected, and when the resistance has passed, it aligns again. This spring-loaded hinge 8g, however, has an elasticity sufficient to accommodate the product and is easily adjustable.

A modification of the surge device for replacing the batten blade is as follows:

together with the rods has a significant mass and makes a reciprocating swinging movements. It even creates a buildup of his swing and the disorder of the machine; the more it increases the frustration and wear on the machine. Therefore, in order to avoid this, the following construction is proposed, which is related to the basic principle: the Gall circuit, infinite and having a lock for length adjustment, bends around two stationary 29a and 29o and one movable 30 chain sprockets and is driven one of the first (Fig. 8 ). The upper line of the chain is parallel or has a small desirable forward bend in relation to the lower shed line. There are two or more such drive kits (viewed across the width of the fabric), and holders 8 are attached to the chain links, one per chain (Figure 8). Holders with the help of racks with hinges 8z carry berd heads with the same tails - teeth 9, as described above. The movement of the chain from the gears of the machine is designed in such a way that in one stroke (shaft rotation) the reed 8a - 9 passes all the teeth and comes to the same position.

At the moment corresponding to the beginning of the surf, the reed grabs the ducks from behind, leads him to the fabric and nails him. Close to the moment of the drive, the upper part of the blade 8a is bent back on the spring hinge using the adjustable support 28 and with a slight pressure on the fabric coming out of the latter ,. With coarse, dense fabrics, the upper part of the blade can be deflected without a support by the fabric itself. Further, with each stroke, the above is repeated. The dotted line shows the position of the reed from under the fabric near the prop (Fig. 8). With such a breaking device: a) its moving masses are many times reduced, b) they make a continuous movement, c) easy adjustment of the density of the surf is possible, d) various Kinematic connections (elliptical gears, etc.) the angle of the complete rotation of the shaft, which corresponds to the surf, in order to ensure the bend of the bend, in order to avoid a gust of the base, in case of engagement with its reed teeth What a device without large dodelok

Easily possible to attach to any existing machine.

According to the inventor, the following advantages are achieved by the proposed construction described above with both a converted batan and a reed driven chain: a) shuttle boxes have a firm, unmoving, fixed position, b) the shuttle passes all the time in the widest possible part of the throat in a strictly straight line, regardless of the batana; the number of outbursts and departures is almost destroyed; it is possible to increase the number of blows with the same basis, c) it is simplified, with the introduction of fixed boxes, the shuttle mechanism and new methods are allowed; all automata are simplified, both for changing the shuttles, and for changing spools and d) construction, as well as to the already working looms of almost all systems by reworking the batanas and transferring the boxes (in the extreme case with the replacement of the crankshaft and connecting rod).

In order to use noiseless bo with some existing bo systems (left side of Figures 1 - 3, in addition to existing shuttle boxes 17 and chutes, a cylindrical box 17a is attached with slots in smooth inside walls. Inside the cylinder there is a smoothly turned cylindrical GONO 23, which is inserted From one or both ends, the plug 27 is made of extremely durable and elastic rubber (Fig. 1). The 8TOT races are connected to the head by the ears. The blow from the latter is transmitted either by the shoulder strap or directly by the plug 27. With Such a device is lightened, but it can also be used with conventional machines. A shoulder strap hits a rubber stopper, or a belt doesn’t have an eyelet, and another rubber insert with a corresponding dimple hits the shuttle. The device is aimed simultaneously at achieving noiselessness and an increase in the number of impacts. An additional cylinder with a bore is attached to the shuttle box 17 (the right part of FIG. 1 and 3). It runs with a race gap, consisting of a cylinder and a rod 22 screwed into it. Between; the spring washer 25 and the lid of the box 17 lay a spring 25 (Fig. 3, 5 and 6). A rubber chamber 24 is attached to the inside of the cylinder a massive rubber drummer for the shuttle, having a valve 24a (Figs. 3 and 5). By means of any known connection, the rod 22 is connected to the styling 21, and the latter through the crank 20a with the stop lever 20, the latter having a hinge with a spring. On a certain part of the stroke of the batten blade 8 (after the weft is captured and before the gear is made), the last noMoiiji of its cam rotates the support 20 and the crank 20 through it, the rod 21, which acts on the rod 22, compresses the spring 25 (cocks the spring). After this, the spring is held in a c3 "atom state" by a known latch (Fig. 3). , Et; the latch, using any known connection, goes to the disengagement set in the form of a cam in the path of the blade. The latter will not hook the cam and will not be able to release the spring 25, while the shuttle has not entered its box, for the reason that when the shuttle has not entered the box, the cam is disengaged from the baton blade. If the shuttle entered the box, then it presses the known design lever 18 and raises (or lowers) the dog 19 (Fig. 1, 2, 3 and 4). This dog becomes between the uncoupling release fist and the batten blade 8, release the latch to the rod 22. The spring 25 suddenly opens and, with force, through the chamber 24 and the rubber head 24, hits the shuttle 5 (Fig. 3). Thus, the batan blade disengages only the cocked spring of the

  G.

the boxes where the shuttle came, therefore it will certainly push one or the other of the races, and release the springs alternately. Spring release, when the shuttle did not enter this box, cannot happen. Similarly, a bat can take the lever 20 for cocking the spring 25 only when the bat goes to the surf, because when it returns, the lever is bent in the hinge and passes the bat without hooking it.

The present invention.
