    The invention relates to the field of the textile industry and relates to a device for pneumatic sealing of a plotter with a weft thread on a weaving machine with a wave-like movable throat. A device is known for charging plotters with a weft thread on a weaving machine with a wave-like movable throat, containing kinematically connected with a drive for moving the plotters of a machine at least one injector connected to a compressed air source, mounted in a holder that can be moved in a direction parallel to the section dki trajectory movement of the plotters of the machine, and located on this site opposite the accumulator plotter to create a weft thread in the accumulator, and the mechanism of but also feed the weft yarn to C11 injector. In multi-field weaving machines, several duck plotters are operated, which at the same time move at small distances from each other. Thus, at a relatively low speed of weft plotter, high performance is achieved when filling the weft yarn. The short distances, at which the weft builders follow one after the other, require a correspondingly short time interval for their refueling. Shuttles that work with spools need to incur relatively high costs for refilling the specified thread, which cast doubt on the possibility of using a multi-link machine. With weaving machines that work with a pneumatic weft dressing in a duck plotter shop, made in the form of a breathable chamber, it can be achieved using relatively simple technical means of significantly greater productivity when weeding the weft compared to using a spool with a wound weft thread. The weft thread of a certain measured length is injected into the magazine with the help of a compressed air injector. The length of the SECONDARY thread corresponds to the width of the corresponding section of the fabric, while a new filling of the weft plotter with a weft thread takes place between two adjacent sections of the MU. The weft thread during refueling in the shop of the duck plotter is wound around the spool. cross winding or accumulating device. This inevitably results in a so-called filament balloon, which is formed by a convergent filament crossing the air across the feed direction. As the air resistance increases in proportion to the square of the speed, the weft thread is very tight, as a result of which its tensile strength limits the unwinding speed of the thread. If you reduce the rate of winding up the thread, you can extend the store of individual duck builders and increase the filling time of the weft store. However, due to the elongation of weft cutters in a loom, the number of systems is reduced, and the productivity of weaving is reduced. The purpose of the invention is to create a device that allows the duck plotters of a multilink weaving machine to be quickly filled with compressed air on a relatively short path of weft plotter movement with a weft thread that matches the width of a piece of fabric without unacceptable weaving tension or extending the weft plotter shop. To achieve the goal, in the device for charging the plotters with weft thread on a loom with a wavy but movable throat, containing kinematically connected with a drive for moving the plotters of the machine, at least one injector mounted to the compressed air source is mounted for movement in the direction parallel to the charging section of the trajectory of movement of the machine plotters, and placed on this section against the plotter accumulator to create a stock of weft yarn in the accumulator Barely, both the mechanism for measuring and feeding the weft thread to the injector, the injector holder has its means of moving in the direction of movement of the plotters with a speed lower than the speed of movement of the plotters by an amount that ensures the injector lags behind the plotter, corresponding to the length of the plotter's accumulator, and means of returning the holder to the original position. The device has a tubular weft guide, mounted in front of the injector. The injector holder is made in the form of a slider and has two sliding guides for its movement. The holder movement device includes a chain drive and a leash mounted on a chain with the ability to interact with the holder, and the return means the holders are reset to the initial position in the form of a spring-loaded rod: Thanks to the fact that the injector moves to the magazine during loading of the weft yarn , there is an extension of the magazine filling time, which is presented for refueling, by the amount that is required for the duck maker to travel a distance corresponding to the distance between neighbors mi duck plotters; If, for example, the injector moves with a duck plotter at half the speed and the distance between two adjacent duck plotters corresponds to the length of the weft thread, the filling time is doubled, which means that the duck plotter is twice as long have a fixed injector. In principle, the difference in speeds of the corresponding duck plotter and the injector is set so that the weft yarn does not accumulate at the store, since the duck is evenly distributed in the store. In order to maximize the entire length of the magazine, it is advisable to move the injector to the duck plotter by the amount that corresponds to the length of the duck plotter shop when refueling the duck to the magazine. To avoid the weft thread being thrown out of the injector when it is rapidly returning to its original position, in certain cases it is advisable to move the weft thread slightly to the injector, for example, the weft thread passes through a transparent plastic pipe or hose. In the manufacture of fabrics that have different weft yarns, at least two Pbs are used: injectors, each of which is conjugated with its weft yarn, one of the injectors, moves from the initial, position for filling the weft yarn to the magazine along with the weft draper, This is the time when the second or other injectors remain in an inoperative position. At the same time, one or several injectors do not work and are located near the path of the duck plotter movement, and the injector, which moves together with the duck plotter, is transferred to the magazine before starting refueling the duck, to the corresponding initial position for joint movement with the plotter. For example, you can select the injectors according to the selected color for the filling of the weft yarn in the weft plotter shop according to a specific program. For this, an electronic control device can be used. Thanks to the use of two injectors, it is possible to save a considerable amount of time when refilling the store of the corresponding gasket. After the filling of the weft yarn into the magazine, the injector takes a certain time to return to its original position. If only one injector is used, this time cannot be used to fill the magazine with a weft thread. With two injectors, when the injector returns, after the filling of the weft yarn is completed in the magazine, the second injector is reset to share with the next duck builder, and therefore immediately. By finishing the filling of the weft yarn in one store, you can start refueling the weft yarn to the next store using the second injector. At the end of the filling of the weft yarn into the magazine, the weft yarn is cut off at the edge of the fabric, it is advisable that the end of the return movement of the injector to its initial position is automatically pulled back into the injector, so that when the next store starts loading, it does not protrude from the injector and its confusion does not occur. The leash, which automatically engages with the injector in the initial position, after a certain injector path is disconnected from it, and the injector is connected to the return device, which returns it to the initial position and has a reverse motion spring accumulating energy when the injector moves. Very simple structural ratios are obtained when the leash is mounted on a chain, one branch of which moves parallel to the injector movement at a speed that is in a certain proportion to the speed of movement of the weft plotter, while at the beginning and edge of the path of movement is guided by guide rollers by means of which the driver moves towards the injector, entering with it into or into the opposite direction, out of engagement with it. Drive unit, i.e. the chain is set in motion by a gear that is engaged with the gear in the moving part of the weft plotter drive, which is moved together with the corresponding weft plotter. In the preferred structure, there are several drivers on the chain, the distance between which is greater than the length of the injector path. The amount that ensures the return of the corresponding injector to the initial position. The duration of the contact of the engineer with the lead corresponds to the time of filling the store. As soon as the filling process ends, the leash releases the injector, as a result of which it can very quickly return to its original position, from which it again moves forward synchronously with the next weft plotter with the help of this leash or the next one on the circuit. In order for the injector to return to its initial position, the uncut end of the thread protrudes from the injector, it is advisable to install a thread guide element in the path of movement of the weft thread to the injector, which fixes the weft thread at the end of the filling to the magazine where returned to its original position, longer than the path to the injector, which, together with the duck plotter, reached the end point of its path. A device may have several injectors, each of which is associated with its own weft thread and may optionally be connected to a driving device. The injectors can be installed on the side of the path of the duck plotters near each other, with the help of the installation device, the corresponding injector can be set to its original position for joint movement with the duck plotter. IF guides are in the form of guide bars, the injectors can be installed between two of them, and the bars are set so that they can move across the movement of the weft plotter. When the filling of the weft yarn into the magazine is completed and the store of the injector vye, the guide rails are moved to the side so that the injector in its irregular position can return to its original position, while the injector intended for the next loading of the magazine is transferred to its initial position for jointly with the duck plotter, the movement is engaged there with the drive device. When using weft yarn, the strength of which allows it to operate at high winding speed, due to which there is no need to lengthen the load time of the magazine, the injectors can be installed in a register that can move across the duck moving direction of the river. After the corresponding load at an intermediate time before the next store starts to fill, the register is moved in such a way that the injector with the necessary color of the weft yarn is reset to the joint with the next weft movement. This movement of the register can be carried out, for example, by means of a gear, depending on the movement of the weft plotter in accordance with the established program, which is contained on the program carrier, for example, a punched card, a cam chain, etc. In front of the injector, a measuring and feeding device can be switched on, having a driven drumJ to the surface of which using pressure rollers periodically press the injector threads, while pressing the individual pressure rollers regulates: s and depends on the movement of the injector. Each injector is connected with a pressure roller, which feeds to it, a weft thread in accordance with the established program. The axial length of the feeder drum is such that the required number of pressure rollers located next to each other can be inserted. Due to the joint movement of the corresponding injector and weft liner, when loading the weft yarn into the magazine, the loading time of the magazine is lengthened, and the achieved elongation depends on the selected difference in the speed of the duck plotter and the injector that is moved with it. Similarly, at a constant speed, the weft yarn is relatively non-. of the movable injector, the rotational speed of the duck plotter can be increased by the corresponding number. It is also possible to double the length of the weft yarn to be placed in the magazine, which allows, at the same feed rate of the weft yarn, to produce wider cloth webs. In this case, a greater number of weft makers work and weaving productivity increases. FIG. Figure 1 shows schematically a multi-ground loom with devices for filling weft yarn, to the weft plotter shop; in fig. 2 shows a device for filling the weft yarn of a weaving machine according to FIG. one; in fig. 3 -. the same, side view, section A-A in FIG. 2; in fig. 4 is a top view in section of the device of FIG. 3; in fig. 5 is a side view in section along the line BB of the device in FIG. 4; in fig. 6 is a variant of the device (FIG. 2), with one injector; in fig. 7 shows the injector according to the following embodiment of the device, top view, with one duck plotter. FIG. 1 shows the multi-link weaving machine of the so-called Backto-Back design. The machine is designed for the simultaneous manufacture of four cloths of cloth 1, which, in the form of bales 2, are installed on one side. Nina Machines 3. The main yarns A, unwound from the 5, installed on the machine bed 3, are split progressively in the direction indicated by the arrow 6, using the button 7 moving across the fabric, with the simultaneous formation of the pharynx 8, at the same time through each throat A duck-laying plotter 9 passes, an example of which is shown in FIG. 2 and 7. The duck plotters 9 move one after the other at a certain distance (Fig. 3) along the guides, which are formed on one side with a reed 10 and on the other side of the helix 7. They are driven by block-shaped segments 1I, moving along the machine bed. These segments, by means of permanent magnets 12, are connected to separate weft pans 9. Segments 11 are attached on one side to an endless chain 11a and guided by two vertical polygonal drive rollers 13 (Fig. 1). Segments 11 are carried on their lower cTopoHe, which faces toward the tails 7, directed to the jade (not shown), which includes legs, made in the rod ends 7.
     Between the reed 10 protrude outward through the warp threads of the lamella 14, which serve to nail the padded weft thread between the weft pans 9 that move one after the other (Fig. 1, pos. 15).
    There are eight plotters per fabric 1 fabric per square foot.
    duck 9, i.e. eight weaving systems. The filling of the weft yarn into the plotter 9 is carried out in the zone between two adjacent webs of fabric 1 using the filling device 16, (FIGS. 2-5) mating with each fabric weaving fabric. The weaving machine (Fig. 1) contains four such devices.
    The device for filling the weft yarn 16 has a sliding guide 17 mounted on two parallel holders 18 of the machine bed 3, which consists of three guide strips 17 installed at a certain distance from each other and installed parallel to the main holder 18 in two transverse slats 19, mounted on the main holders 18. Between the two guide rails 17, a slider 20 is installed, carrying an injector 21, to which the refining thread 22 coming from the feeding device 23 or 24, which unwinds the specified thread cross winding of the bobbin 25 or less. 26. Injector 21 (FIG. 3) is adjacent to the accumulator 27 of the duck plotter 9.
    Below the slide 17
    runs alongside the warp threads, formed by the sheds 8, the upper branch of the endless chain 28, which is guided by two guide rollers 29 mounted on the respective axes 30 or 31 on one of the main holders 18. One of the guide rollers 29 is rigidly connected to a cog wheel 32, which is located in a setting with a cog wheel 33; SELL 1 CIM on a shaft 34 installed in the main holder 18. The cog wheel 33 through a shaft is rigidly connected to the cog wheel 35 located on the other side of the main holder 18. The cog wheel 35 is in engagement with the toothed rack 36, which consists of individual sections having a length of segment 11 on which they are attached.
    As can be seen from FIG. 1, a rack 36 which moves past the gears 35 of the device for refueling the weft yarn 16 at the speed of segments 11 and passes the chain 28 at a speed that is synchronized with the movement duck plotters 9 that are magnetically carried by the segments 11. Its relative speed relative to the speed of the duck plotters 9 is determined by the reduction of the gear train 32-35.
    The chain 28 bears on itself (fig. 5) four powered teeth 37 installed at the same distance from each other. The upper branch of the chain 28 is parallel to the guide 17 so that each driver 37 captures the ram 20 of the injector 21 located in the middle (FIG. 3) in the initial position I (FIG. 3), and moves along the guide 17 by a predetermined distance to the final position II. The corresponding driver (Fig. 5) by means of the right guide roller 29 moves radially to the slider 20, which is in its initial position, and engages with it, and the left guide roller 29 pulls the driver 37 radially from the guide 17 and leads it automatically engaging with the slider 20.
    Each injector 21 is connected to a return device, made in the form of spring thrust 38, which is in contact with the injector and is fixed on one side to the housing 39. The stop 40 is tightly coupled to which half 20 lies in the initial position and which limits its returnable.
    The guide 17 carries two protruding coaxial bolts 41 and 42 on the side, which are inserted into the corresponding apertures 43, 44 of the main holder 18. One of the bolts 41 of the element 18 is on the outside under the action of the pressure spring 45, which rests with its end into the bottom of the sleeve 46, inserted into the element 18, and pressing the guide 17 (FIG. 3) in the right position to the opposite main holder 18. The other bolt 42 rests with its end on the double-shouldered lever A7, pivoted on the main bearing holder 18. The double shoulders lever 47 carries on pressing the roller 48, which can engage with the curved guide 49 located on the corresponding segment 11 in the area of the rack 36 (Fig.4 With each injector 21 there is a matching thread 22 or 22a (Fig. 2), which is pressed according to the program with the stifling roller 50 or 50a on the circumference of the thread-feeding drum 51, which rotates at a constant speed and is part of the measuring and feeding device 52, coupled with one of the devices for filling the weft yarn 16. The movement control of the pressure rollers 50, 50a is impl The gear wheel 53 meshes with the gear wheel 35 depending on the movement of the weft rollers 9, and both rollers 50, 50a are controlled individually according to the program. The weft pliers 9, driven by the segments 11, move at a certain distance from each other at a certain speed through the throat. If the weft patcher 9 enters the devices for filling the weft yarn 16 (FIG. 5, right), one of the injectors 21 (FIG. 3, right) is in the initial position I (in which it is in the path of the leash 37). The injector 21, starting from the initial position I, is pulled by the leash 37 and its movement is synchronized with the movement of the weft plotter 9. It is transferred with a certain speed to the final position II, in which the dock 37 leaves the engagement with the slider 20. The motion of the leash 37 is so coordinated with the movement of the duck plotter 9, that the injector 21 carried by the lead 37 on its way between the initial position I and the final II moves with the plotter duck 9. The gear ratio between the movement of the chain 28 and the duck plotter 9 is chosen such that m of joint movement of the slider 20, the injector 21 is moved relative to the weft plotter 9 by the length of the weft magazine. During co-movement of the injector 21 with the weft-plow 9 with the press roller 50 or 50a, coupled to the pitcher with its thread 22 or 22a, is pressed against the feed drum 51, as a result of which the refined thread is fed into the injector 2t, and then it is blown into weft yarn accumulator 27. Once the weft yarn is finished and injector 21 has reached end position II, the weft thread is cut off at the edge of the fabric using a cutting device (not shown), while it is partially stuck into the fabric, after (| tksirovanny and laid the following plotter the duck 9 into the throat of the cloth 1. Since during the joint movement, the injector 21 with the duck plotter 9 accumulates energy from the spring drive 38, the slider 20, after being released through vodka 37, instantly returns the spring drive 38 to its original position I, in which it is adjacent to stop 40. The initial circumference of the gear 35 corresponds to the length of the weaving system (or a multiple thereof). The gear 32 moves with a gear ratio of 2: 1. The distance between the leads 37 on the chain 28 in the illustrated embodiment is one fourth the length of the system. With a system length of 24 cm, the leash makes a 12 cm path between both positions I and II. I If the length of the storage weft iy. ti 27 10 cm, with a 2: 1 gear ratio, injector 21 accompanies shop 27 between positions I and II on a path of 10 cm, which means that a route corresponding to a magazine length of 20 cm is available for filling the weft yarn into drive 27 Since the distance between the leads 37 is 12 cm and the injector 21 with a zapraks of the weft thread passes only 10 cm, the remaining part of the track of 2 cm is used to return the slider 20 and the injector 21 from the final position II at this time using a spring actuator 38 to the original I. Thanks to this, a return Putting the slider 20 back to its original position before it is captured by the follower leash 37 and moved to end position II. The weft threading process can be improved by leveraging the remaining time; to return the injector 21 from end position II to the original I. For this purpose, use the second injector (Fig. 3-5). When the left injector (FIG. 5), which corresponds to the average injector of FIG. 3, arrives at the end position II, the pressure roller 48 (FIG. 4) hits the curved guide 49 of segment 11. Due to this further movement of segment 11 by means of the lever 47 and the bolt 42 of the slide guide 17 is shifted to the left (FIG. 3), as a result of which the injector 21 with its slider 20 is transferred from the lateral position of the chain 28 to the initial position I, in which the slider 20 is located on the path of the leash 37. At the same time, the injector 21 is in the end position II, having finished filling the weft thread coming out of clinging nor with the leash 37, as a result of which he can move the back of the leash 37 and the chain 28 to the stop 40, while the second injector is already caught by the leash 37 and thus begins refueling the weft yarn. The position that the first injector 21 occupies when it returns, being on the side of the chain 28, is shown in FIG. 3 left dotted line. As soon as the second injector finishes filling the weft yarn, the pressure roller 48 again leaves the curved guide 49, as a result of which the slide guide 17 (Fig. 3) moves to the right and the first injector at its slider 20 is caught by the next tooth of the leash 37, at that time when the other injector becomes inoperative from the side of the chain 25, as shown in FIG. 3 on the right; Thus, both injectors are alternately attracted to thread the weft yarn. When several injectors 21 are used, they can be controlled by a software device and the injector color can be changed using the injector 21. In this case, the control of the sliding guide 17 can be carried out by means of the rack and the gear with a software device using the approach of the first adjusting device, which causes the sliding slide 17 to move back and forth with a two-branch lever 47. The filling device 16 of the weft yarn 16 can perform so that it will work with only one injector 21 (Fig. 6). FIG. Figure 7 shows another embodiment where the designated four injectors 21a-21d are combined with pressure sliders. one register that can move as its sliding guide 17 across the path of movement of the weft plotter 9 according to the set program. Thus, it is possible to follow each other duck pliers 9 to supply four different weft yarns. The reciprocating movement of the register formed by the injectors 21a-2ld, indicated by the arrow, is carried out according to the program with the help of a software device and the adjusting device controlled by it. The invention is described on the basis of a double-sided weaving machine, it can also be used for a circular weaving machine or a weaving machine of a different design. A thread guide element in the form of a fixed pin (Fig. 2) is installed between the thread-giving drum, 51 and the injector 21 adjoining it, which is positioned so that the path of movement from the locking thread of the pin to the injector located in the initial position I is longer the path to the injector located in final position II. This means that after the weft thread is cut off, the injector located in the final position, with the return motion of the injector to its initial position, the I shaped end of the weft thread is pulled into the injector and does not protrude from below. i .1 In addition, an injector (Fig. 2) is put on a pipe that can be made in the form of a flexible ishang, preferably transparent, which provides the lateral direction of the weft thread on the path between the thread-giving drum and the corresponding injector, as a result of which the weighted thread cannot accidentally exit the injector.
