    I-Tracking devices (Figs. 7-10) are installed inside the opposite panel 29, which holds the elements for gripping the filaments at the points where they enter the device. Such 5 gripping devices are formed by movable and fixed elements. The stationary ones have a pair of flexible bands 43 and 44 (Fig. 2) installed between the panel 29 and the plate 45, 10 attached with spacers 46 at some distance from the wall in the area between the quum guides 30 and 31. The pair of bands 43 forms a free the space opened in the direction towards the guide 30, and the pair is hollow; 44 forms a free space in the direction of the guide 31. The levers 47 and 48 constituting the movable elements of the claws are fixed for communication with the indicated pairs of strips 43 and 44, respectively. The two levers 47 and 48 are pivotally mounted with respect to the axes 49 and 50, which also serve to fix the plate 45 25 to the panel 29. The levers 47 and 48 move between the panel 29 and the plate 45, and their free ends pass through the pair LFSR 43 and 44 respectively. Lever 47 has a round protrusion 51 which engages with you | capacitive 52, which is located in lever 48. The latter also contains a second profiled lever 53 with a profile edge 54, to which a pin 55, 35 is located located on the control lever. ge 56, pivotally attached (at position 57) to the wall 29.

The ends of the upper levers, Ffg. 9) 60 and 61 act on the ends of the strands inserted into the guides 30 and 31. The lever 60 includes a circular protrusion 62, which engages with a recess 63 in the lever 61. One end of the coil spring 64 is wound around a finger 65 attached to the panel 29 and acts on the lever arm 60, while the other end is opposite the other finger 66 attached to the panel 29. The spring 64 holds the lower arm of the lever 60 in contact with the adjustable stop 67, and thus keeps both the levers 60 and 61 in a certain position. The stop 67 can move and stop at the desired position in the slot 68 located in the panel 29. In FIG. 9 shows two adjustable stop positions 67 and the relative position of two rachagas 60 and 61 under the pressure of the spring 64. When the stop 67 moves fully to the right in the groove 68 (as shown in FIG. 9), the ends of the upper arms of the levers 60 if 61 are raised the action of the spring 64 on one line with the inner edges of the guides 30 and 31 (the position psghazano solid lines), while moving the stop 67 completely to the left in the groove 68, the ends of the upper pepech levers 60 and 61 | to another. In this case, the levers 60 and 61 practically do not pull out the free ends of the two threads connected together, and they have the maximum length, while in the second case the free ends are respectively stretched and have the minimum length By adjusting the stop 67 in the intermediate position, the length of the free the ends of the threads connected together can have an intermediate position between the maximum and minimum.
    The lower arm of the lever 61 has a profiled edge 69 with which the profiled portion 70 of the control lever 56 is associated. hinged at position 57 and rigidly connected to lever 58.
    FIG. 7 shows the elements for gripping the yarns and the elements for adjusting the length, the free ends of the yarns in the zero position, while
    in fig. 8 and 9, these same poke elements are in a corresponding working position. Actuator .. cut-off0 (valve 1 is installed inside panel 29. Actuator consists of a slide 71 (Fig. 4 and 10), having two longitudinal grooves 72 and 73, with which it is guided along two fingers 66 and 74, attached to it. to the panel 29. The spacers are mounted on the fingers 66 and 74, holding the slider 71 in a plane that is parallel to the panel 29, but on: runs a greater distance from it than the plane in which the levers 60 and 61 move (Fig. 4 Grooves 72 and 7.3 limit the maximum stroke of the slider 71. From above (Fig. 4 and 10), the slider 71 contains a fork 75 located at an angle of 90 to the plane the slider, the plug 75 engages with the free end 76 of the stem 77 of the valve 18. The stem 77 passes with a seal through the cover 78, the closing chamber 19, in which the valve 18 operates. Between the insert of the cover 79, rigidly fixed with the cover 78, and valve 6 (Fig. 4) the coil spring 80 acts and holds the valve 18 pressed against the seat 17, thus closing the passage for compressed air reaching the chamber 19 in the direction of the channels 15 and 16 and in the direction of the hole 14 in the mixing chamber 13. The spring 80 holds also the slider 71 in the raised position (phi . 4 and 10), with the slider hooking the end 76 of the stem 77 of the valve 18 with a hook.
    On the side facing the panel 29, the slider 71 holds the rod 81, on which the end of the lever 82, pivotally mounted with respect to the finger 83, fixed in an adjustable position to the panel 29, can act. The finger 83 holds the corresponding strut to install the lever 82 in the plane , separated from panel 29 and parallel to it, so that this end acts on p 81, which is held by the slider. 71
    The finger 83 can move and stop at the required positions in the groove 84 in Gtanul 29 and in two end positions that the finger 83 can occupy (Fig. 10).
    The lever 82 comprises a profiled edge 85 with which the second finger 86 can act, held by

    control lever 56 on the opposite side to finger 55.
    When the pivot point (pin 83) of the lever 82 is adjusted in the lower position in the groove 84, the rotation of the control lever 56 causes the finger 86 to cause the maximum rotation of the lever 82, and this maximum stroke of the slide block 71 corresponds to the maximum opening time of the cut-off valve 18. With On the other hand, when the axis of the hinge of the lever 82 is adjusted to the highest position in the groove 84, the stroke of the slide 71 is minimal, as is the opening time. clan 18.
    Thus, one control lever 56 and lever 58 rigidly connected to it control three different types of elements mounted on the panel 29, movable elements 47 and 48 gadgets for filaments connected together, adjustable with finger 55, levers 60 and 61, which regulate the length of the free ends of the threads, controlled by the profiled part 70, with such a control being regulated and, finally, with a slider 71 to open the shut-off valve 18, adjustable with a finger 86, while such a control can also be adjusted.
    The control drum 87 (Fig. 3) is held in respective bearings (not shown) in the design of the device 10 for stepping movement of a pair of levers 56 k 58 and levers 35 and 36, which constitute) the connecting elements for the threads.
    The drum 87 is made in the form of a cylindrical spatial cam, contains three KjpyroBbik grooves 88-90, which have an appropriate profile to determine the necessary synchronization of the movement of various elements in the desired sequence.
    A roller 59 located on the lever 58 and rigidly secured with the lever 56 is inserted into the groove 88, and the rollers 39 and 40 located on the levers 35 and 36 for intersection of the yarn are inserted into the grooves 89 and 90, respectively.
    The drum 87 may, by means of a clutch 9, communicate with the shaft 8, which is drive for an automatic winding machine. . A single turn through the 360 reel 87 corresponds to one complete cycle of joining two strands.
    At one end of the drum 87 (to the left of Fig. 3), there is a frontal cop 91 (Fig. 5), with which it is associated. a roller 92 located on the shoulder of the double arm 93 pivotally fixed in position 94 to the design 11; the other arm of the lever 93 has a roller 95 which engages with the fork 96 of the lever 97 rigidly connected to the square finger 27, on which the support 26 dl is attached krppki 23. When rachag 93 steps relative to the axis 94 under the control of the frontal copier 91 of the control drum 87, the cap 23 moves from the initial position (Fig. 4), B1 1, from the mixing chamber 13, to the position in which it closes the chamber in front of it .
    On both sides, the support 26 for the cap 23 contains protruding shoulders 98, KOTOiM) i.e. it acts as an ejector for the threads from the chamber 12 after they are joined. The two arms 98 move together with the rim 23 close to the two sides of the cage 13.
    The support 26 of the yoke 23 also on both sides has small levers 99 (Fig. 3), which serve to precisely set the threads connected together during their insertion into the chamber 13.
    The cutting elements for the free ends of the filaments are also mounted on an Osc 27 supporting the support 26 for the kryppka 23 on both sides of the support 26. Each such cutting element contains a fixed knife 100 (Fig. 5), which with the aid of a hole in it is mounted on the axis 27 so that the latter could rotate freely relative to a fixed knife. The fork 101 on the fixed knife 100 engages the rod 102, which is mounted with its axis parallel to the axis of the finger 27 in the design 11, so that the fixed blade cannot rotate. A fixed blade 103 is associated with a movable 103 which is rigid with the axis 27 and performs a periodic rotational motion. A spring 104, acting between the support 26 and the fixed blade 100, keeps this blade pressed against the movable blade 103.
    The screws 105 of the support 106 (FIG. 2) in the form of square levers are fixed with on the support 11 from two sides of the block 12 and have protruding parts 107 dp of the exact direction of the threads when

    inserting into the device. On axis 108, a double lever 109 is pivotally mounted on the frame of the support 106, and at the end of one of the arms there is a gripping element 110 designed to work with the extension of the protruding part 107 to stop the thread immediately upon exiting the mixing chamber 13. Spring 111 meldu by a protrusion 112 on the support 106 and the protrusion 113 at the end of the other arm of the lever 109 holds the gripping element 110, remote from the protruding part 107 (Fig. 2). On the opposite side of the protrusion 113, the other arm 114 of the lever 109 is opposite the porsch 115 moving in the sealed chamber 116 in block 12. The two chambers 116 (Fig. 6), which have opposite pistons 115, are coaxial and both are open to the channel 16, which through the channel 15 communicates with the opening 14 opened into the mixing chamber 13. Obviously, when the shut-off valve 18 is open and the compressed air reaches the channel 16, the two pistons 115 move outwards from the respective chambers 116, which, having overcome the force of the springs 111, they force levers 109 turn carry the axes 108, the gripping elements 110 are brought into contact with the bases of the matching protrusions 107, and thus, the thread stop immediately upon their exit from the mixing chamber. The purpose of such a gripping device is to prevent the wobble, which the strands tighten when joined together with compressed air in the mixing chamber 13, from spreading outside the chamber, since the gripping points are between the flexible strips 4.3 and 44 of panel 29 and 1; Chases 47 and .48.
    The device works as follows. V
    It should be noted that in FIG. 1-7 and 11, all elements of the device are shown in their original position.
    When the thread breaks with the cob 1 and the bobbin 4 on an automatic winding machine, the elements of this machine, designed to keep the coil from cob 1 and the other thread from the spool 4, begin to work. They usually consist of corresponding movable levers installed with suction ports to hold the filaments under.

    tension, automatically insert the two threads into the device 10. The arrangement is such that both threads enter the device from the side which has the panel 29 and exit the device with the free ends from the side of the panel 28 where the ends of the threads are sucked | qimi. elements of the winding machine. In particular, the thread starting from the bobbin 4 may be located in directions 30 and 32, and the thread that starts from the cob 1 may be located in the guides 31 and 33. In this position, two threads are located at the sides of the mixing head. camera 13 perpendicular to its longitudinal axis. At the same time, each thread is installed in the space between the protruding part of the G7 and the grip 110. The Fo1SH1a is protruded by the parts 107 and the block 12 facilitates such an arrangement. Once the threads connected together are inserted into the connecting device 10, the drive of the automatic winder 6apa6iiH 87 to start the joining operation, which is performed during one full turn of the drum 87, after which the Power take-off
    automatically terminated. I
    The first stage of operation is the intersection of the threads with the help of levers 35 and 36, which are governed by profiled Canadians 89 and 90 on Barbara 87. From the position in which they are placed fully to the right (Fig. 11), both levers 35 and 36 are shifted to the left so that the hook 37 lever 35. grabs-. The saeT thread passing through the guide 32 moves it completely to the left, but the hook 38 of the lever 36 does not catch the thread passing through the guide 33. The lever 35 then remains on the left and holds the thread in such an offset position, and the lever 36 moves one back to the right. During such movement, its hook 38 carries the thread passing through guide 33 to the right. At the end of such an intersection stage, the lever 35 remains -. With the thread held by the tear (Fig. 11), the lever 36 remains with the other thread held to the right. The two threads are intersected, thus, in the area between the panel 28 and the mixing chamber 13, at ET0M such threads are directed at the base of the stand
    25016612
    of the floating parts 107, then extends into the guides 30 and 31 in the opposite panel 29. The levers 47 and 48 have already begun their mutual movement
    5 in this stage, but without trapping the filaments Between pairs of flexible bands 43 and 44.
    After the intersection of the two strands, the frontal pin of the control drum 87, using levers 93
    to and 97, causes the cover 23 to move,
    leading to closing, and moving. Moving knives 103 of the cutting device During the closing of the lid 23, the levers 99 are rigidly connected
    15 with the base, the threads are guided during their insertion into the mixing chamber 13, and their position is determined accurately. Immediately after the frontal closing of the camera 13 with the help of the lash-:
    20 and 23, the movable knives 103, together with the fixed knives 100, cut off the free ends of the threads. After the free ends are cut, the levers 47 and 48, adjustable by the cam, grip the threads between the knives at the panel- 1 or 29 and the levers 60 and 61 also begin to adjust the length of the cut free ends of the two threads .. ,,

    The slider 71 then opens the shut-off valve 18 and the pressurized air is supplied to the channel 16. The pistons 115 are directed outward and rotate the levers 109 to catch the threads immediately at the outlet of Them from the mixing chamber 5 ry 13 between the gripping elements 100 and the bases of the projections 107. At the same time, the compressed air also enters the chamber 13 through the opening 14 and the two strands are joined together by mixing and interlacing their fibers. The duration of the charge of compressed air in the mixing chamber 13 for this -. The speed of rotation of the drum 87 depends on the cam profile, which determines the opening and closing of the shut-off valve 18 and the adjustment of the finger 83 in par. 84. As soon as the cam pushes the slider 71 down (Fig. 4) with springs 80, clap 50 pan 18 is closed and the thread joining stage is completed. At the same time, under the pressure of the springs 111, the pistons 115 and the levers 109 return to their original position and the connected threads
    55 are released from the grippers 110. Krsh1-ka 23 begins to move to open, and with the help of protruding arms 98, the removal of the connected
    from the chamber 13. At the end of the movement to open the cover 23, a pair of levers 47, 48 and 60, 61 is returned to its original position, while the lever 35, which performs the interlacing operation, has already returned to its original position i.e. during the entry of compressed air into the chamber.
    The rotation of the spool 4 and the movement of the movable guide 3 are again repeated by the winding machine so that the connected threads are completely removed from the device 10. Such extraction is facilitated by the concave shape of the block 12. The control drum 87 stops in its original position when the rotation from the drive stops. The device 10 with all the movable elements is ready to repeat the operation.
    The proposed device is structurally simple and allows performing operations with high reliability and safety. The movements of all feeds are regulated with the help of buns on a single drum. Such cams perform
    direct control and do not require elastic means that may be subject to fatigue. Accordingly, the connection operation can be performed at high speed, with constant time and reliably. Since the original principle of adjusting the movement of the three different elements is carried out using a simple copier, in particular the cam of the drum 87, the design can be simplified and the overall dimensions of the device are significantly reduced. ,
    When crossing the threads before inserting them into the mixing chamber, they retain a more comfortable position in the chamber when connected.
    Due to the ease of adjusting the length of the free ends of the threads between the maximum length and the minimum and because of the ease of adjusting the duration of the compressed air supply to the mixing chamber between the maximum and minimum time, the device can easily be adapted to different types of operating conditions, in particular to different types of nit m, fiber length, etc.
