    The invention relates to a multi-field weaving machine with permanent-magnet drive for weft yarn plotters.
    The purpose of the invention is to increase reliability in operation, reduce noise and increase wear resistance.
    Figure 1 shows schematically the proposed weaving machine, axonometric view; FIG. 2 is a section A-A in FIG. on fig.Z - section bb in figure 2; on Fig - section bb In figure 2; figure 5 is a section of the GG on fig.Z on Fig.6 - section dD in fig „5.
    The loom contains a frame 1 made for the simultaneous manufacture of four webs of fabric 2. Each of the webs of fabric 2 is wound on a product roller 3 mounted on the frame 1 of the machine so that it can be rotated. Navoi 4 with base 5 is mounted rotatably in the lower part of frame 1, and at base 5, in direction of arrow 6, helium 7 moving transversely to fabric webs 4 form running throat 8, with one shredder passing through each throat 9 weft yarn. (Fig.Z and 4).
    Plotters 9 weft threads follow each other at a certain distance (FIG. 2) along a path that on one side forms a guide reed 10, and on the other side plates 11 for sample weft threads that can be rotated on the machine 1 placed on the base plate 12 with the help of the hinge 13. The movement of the plates 11 is limited by the teeth of the guide reed 10 and by means of the guide rods 14 mounted into the plate 12. The mechanism that performs their pivoting movement (not shown) consists of two schayuschihs with weft yarns 9 plotter rollers.
    The trajectory along which the plotters 9 weft threads pass contains two straight line sections 15a (Fig; 2) and two adjoining ones, curved in the form of a semicircle of a back curvature section 15b. Along this path, the plotters 9 of the weft yarns are moved in the same direction by means of the drive segments 16, which are in contact or directly with each other at the hinge points.
    connections 17, or attached, located near each other, to the endless chain 18 by hinges 19 (Fig. 4), while passing through the straight sections 15a, the segments can be adjacent to each other by their adjacent end surfaces 20 (Fig. 2 or located at some distance from each other.
    Thus connected into an infinite chain the segments 16 on curved sections of the inverse curvature 15c are displaced by means of the machine installed in the frame 1 with the possibility of rotation around the vertical axis of the sprockets 21, at least one of which is connected to a machine drive (not shown) that informs the segments 16 movement in the direction of the arrow 6 in figure 1.
    On the machine bed 1, the individual segments 16 are moved in the horizontal and vertical directions on the respective guide rails, for example, indicated by the position 22 in FIG. On the lower side facing the henches 7, the segments contain control channels (not shown) in which protrusions made on helix shafts 7 enter. Each time, before entering the shed 8 fabric webs 4, weft threads are sequentially charged from the bobbins 23 s. using the device 24 for charging plotters with pieces of weft yarns. Each of the segments 16 on the front side facing the path of the weft yarn plotters 9 comprises a rectilinear surface 25, which runs under a right angle. scrap to the end surface 20 and to which the surface of the poles of a certain number, in this case six, permanent magnets 26 located one near the other at a certain distance. In a corresponding manner, each plotter 9 of the weft yarn on the side facing the surface 10 is provided with permanent magnets 27, the surfaces of which are covered with a slip film 28 (FIG. 3 and 4) and synthetic material. As a result of the interaction of the permanent magnets 26 and 27 a magnetic coupling between the plotters of 9 weft threads with segments 16, with each segment 16 being given an oline plotter 9 of weft nitio
    the non-linear trajectory sections, the plotters 9 of the weft threads, captured continuously and synchronously by the moving drive segments 16, rest on the guide reed 10, while the surfaces of the poles of the permanent magnets 26 and 27 facing each other are fixed at a distance from each other due to the guide reed ten"
    The guide reed 10 extends mainly along the fabric forming zones 4 of the straight line portions 15a. If you look in the direction of movement of the plotters 9 weft threads, then a removable pad 29 (Figures 2 and 4) adjoins the guide blade 10 wedge-shaped in cross section, which until the transition to the curvilinear sections 15b transfers the plotters of 9 weft threads to a flat surface of 25 segments 16, so that plotters fit directly to the segments.
    Since the air gap between the opposed surfaces of the poles of the permanent magnets 26 and 27 is caused only by the thin slip film 28, a large magnetic attraction is created by which the plotters of the 9 weft threads are kept on the surface of the 25 segments 16 when the curvilinear plot 15 in their trajectory. Even with a high speed of 9 weft threads plotters, it is guaranteed that centrifugal forces appearing on sections 15 of inverse curvature 15c will not cause the plotters of 9 weft threads to shift or even detach from their segments 16.
    After passing through the arcuate section, the plotters of the 9 weft threads, when approaching the guide reed 10 of the straight path section 15a, must again be transferred to the reed guide 10. For this purpose, each drive segment contains a lifting device made in two parallel and located at some distance from each other, the rods 30, which are mounted so as to move at a right angle to the surface 26 and extend in the respective support holes 31 of the ribs 32 of the segments 16. Each of the rods 30 n It comes under the influence of a returnable Yruzhina 33, which tends to squeeze

    the rod (Fig. 4) to the right, to the position in which the left outer end of the rod 30 is at some distance from the guide 10. This position is determined by a stop pin 34 which can rest on the corresponding edge 32 and which the return edge relies on. spring 33.
    The distance of two rods 30 from each other is chosen so that the latter come into contact with the plotter near the front and rear ends of the corresponding plotter of 9 weft threads, as shown in Fig. 4.
    The control of the rods 30 of the individual segments 16 is carried out with the help of the control cam 35 (FIGS. 2 and 6), which is fixedly mounted on the base 1 of the machine in the transition zone from the semi-circular section 15c to the linear part-1 current 15a of the trajectory. Cam 35 contains when viewed in the direction
    movement of plotters 9 weft yarns} ascent section 37a with a significant inclination relative to the rectilinear trajectory of movement of the segments 16 and rectilinear section 15a of the trajectory to which the movement contour parallel to the movement trajectory or with a slight inclination to the last 6.
    The cam 35 is mounted on the straight-line portion 15a of the path, so that during its operation the corresponding plotter 9 of the weft thread is no longer exposed to centrifugal forces appearing on the curvilinear portion of the path of motion.
    In the direction of movement of the weft yarn plotters 9 in front of the guide reel 10 shown in Fig. 6
    partially installed, wedge-shaped in cross-section of the lifting platform 36, fixedly mounted on the plate 12 and directed by its contraction against the direction of movement
    (arrow 6) plotters 9 weft threads.
    In front of the lifting platform 36, a fixed one is installed, passing inside at an angle to the trajectory of movement.
    segments 16 is a curvilinear surface 37, which forms a safety device that provides a forced return of the incident to the curvilinear surface 37
    the rods 30 to their original position when the return spring 33 fails, so that they do not run over the lifting platform 36 or the guide reed 10 and cannot damage any of these elements.
    The machine works as follows
    With the passage of, for example, the lower rectilinear section 15a of the trajectory (Fig. 2) in the direction of the arrow 6, the weft yarn plotters moving at predetermined distances one after the other and connected by magnetic forces to the segments 16 are pushed into the corresponding gap 8 they contain. weft yarn0 In this case, they move with their sliding film 28 along the guide reed 10, which limits their movement and against which they are pressed by the forces created by the permanent magnetite 26 and 27 "
    After leaving the fabric 4 left from Fig. 1 and moving to a semicircular curvilinear section 15b, each plotter 9 of the weft yarn enters the removable platform 29 in the manner described above onto the surface of the corresponding segment 16, on which the plotter is fixed with considerable force, since the air gap between the related surfaces of the poles of the permanent magnets 26 and 27 is very small.
    The state immediately prior to the described descent of the corresponding weft yarn 9 from the guide surface 10 is shown in FIG. 3 and 4. The rods 30 are fixed by the return springs 33 in the initial position, in which contact with the guide beam 10 is prevented.
    After passing the curvilinear section 15c (figure 2 at the top), each of the segments 16 falls with its rods into the area of action of the control cam 35, which, if necessary, is installed with the possibility of permutation along the guide and along its height.
    As shown in FIG. 6, the rod 30, which is first front in the direction of movement, contacts the lifting section 35a of the cam 35, which has a greater inclination, whereby the plotter 9 of the weft thread, overcoming the permanent mas

    By threads 26 and 27, the force is gradually removed from the surface 25 until the rear bar 30 begins its removable movement. The weft plier 9 is first set at an angle to the plane 26, which has the advantage that the removable force is not applied immediately, but gradually as the weft yarn plotter 9 moves forward.
    Through the cam transfer section 35c, with the help of the last rod 30 interacting with the last rod 30, the plotter 9 of the weft thread is installed at such a distance from the surface 25 of the segment -16 that it slides easily along the lifting platform 36 upon its further advancement and thus is transferred to the adjacent guide reed 10 and at the same time, large braking forces acting against the direction of its movement, which could lead to the displacement or disruption of the plotter 9 of the weft thread from the segment 160, do not affect it.
    With the transfer of the weft yarn plotter 9 to the guide reed 10 of the rod 30, the cam 35 is retracted, so that they can again take up their original position under the influence of the return spring 33.
    Before inserting the fabric webs 4 into the webs 8 of the weft yarn 9, weft threads are inserted into the devices 24 to charge the weft yarns, which the plotter 9 runs further into the orifices 8.
