Description

The known devices for tying the yarns, made in the form of plastic knotted knots, with a cutting blade in a hook, bind the ends of two fixed yarns.

The described device for tying the threads yarns the yarn to the end of the converging one, and the tie occurs on the way, without stopping the bobbin, reel or cartridge, on which the thread is wound.

FIG. 1 is a diagram of a device for tying strands; in fig. 2, 3, 4, 5, 6, 7, 8, 9, 10, 1, L2, 13, and 14 — schemes of action of details of the device; in fig. 15, 16, 17 and 18 - the formation of the node iia at various stages of the operation of the device; in fig. 19 is a diagram of a modified strapping device; in fig. 20, 22, 23, 24, 25 and 26 - diagrams of the action of parts of a modified device; in fig. 21, 27 and 28 - knot formation at various stages of action of a modified device.

Nodes 1 (Fig. I) is mounted on a round rod 2. On the side of the rod 2, there is a notch 3, which is formed by a plate 4 (Fig. 2), mounted on the right side of the rod. Below the notch 3, the rod 2 has a square cross section 5 and a round rim 6, under which there is a screw 7 with a screw rim 8, making 1.25 turns and over 0.75 turns passing into the right side 9, ending with an emphasis 10 Under the screw 7 there is a chamfered drum // with a vertical cut 12. A short tube / -) with a bent rim 14, having a square hole in the size} of the square rod 5, is put on the square rod 5. There is a free gap between the rim 14 and the rod 5. On the tube 13, the conical brush 15 and block 16 are fastened. In the free space between the square rod 5 and tube 13, a spiral spring 17 covering the square rod 5 is installed. The short tube 13 is fixed in stationary bearings and can rotate around its axis, resulting in movement from the cord covering the block 16. Inside the tube 13, together with it.

№ 86561 ,,

rod 5 rotates with all the parts fastened to it. When rotating, the rod 5 rises up to the appropriate limit, and saTeJvi, under the action of the decompression force of the spring 17, again goes down,

On the round rod 2, the zatelle knot / is fastened, having in the upper left corner a recess 18 (Fig. 3) formed by a knife 19. On the left side of the knob 1, there is an opening formed by bending the longitudinal end, into which the rod 20 enters (Fig. 4 ), integral with a flat spring 21. The right end of the spring 21 enters the inside of the rod 2, and the left end of the spring, when pressed, goes down, lowering the rod 20. When the pressure is stopped, the spring 21 and the rod 20 return to their original position . The rod 20 closes the recess 18, opening the entrance to this recess when it is lowered down.

There are a quadrangular window 22 in the knots, across which is an axle 23 in its upper part, on which the hook 24 rotates while transversely moving the part 25. The ends of the hook 24 enter the upper quadrangular hole 26 located on the knots /. The hook 24 has a stepped branching, in the form of rods 27 and 28 (Fig. 5), having ends bent at an angle of 90 ° 29 and 30. At the bottom, the hook 24 has a finger 31 that fits into the slot formed by the plates 32 and 33 of the part 25. Part 25 is a spring plate, the lower end 34 fixed on the rod 2. When pressing the slide 55 (FIG. 6), the part 25 moves to the right and turns. hook 24 on axis 23 by 90 °. After cessation of pressure on slide 35, spring 34 and hook 24 return to their original position.

The part 36, swinging on the axis 37, is bent in the lower part at a right angle, and in the upper part is rounded and has a sponge end 38 (Fig. 7). Against the sponge 38, the fixed sponge 39 is symmetrical to it. When lowering the round rod 2, the end of the part 36, abutting the plate 4, will make a turn at the right angle, while the jaws 38 and 39 will be pressed together at the top. When the round rod 2 lowered to the end, the end of the part 36 is freed from the action of the plate 4 of the round rod 2, since there will be a hell of the upper cut of the round rod 2 and the plate 4 and, under the action of the spring 40, the jaws 38 and 39 will open.

The rod 41 of the lower curved end 42 is brought under the roller 11. At the top, the rod 41 has a slot 43. The lever 44 (Fig. 8) is fixed with the lower end on the fixed axis 45 and can be rotated on it. The finger 46 of the lever 44 enters the slot 43. In the lever 44 there is an eye 47 through which the thread moves freely when winding it on a roller, a reel, etc. On the hook 48 of the lever 44 parallel to the moving thread in the eye 47 is spare a thread with a full package for binding it to a moving thread. To hold the rod 41 and the lever 44 in the upper position, there is a flat spring 49 that abuts from below into the bent end 42 of the rod 41. The lifting of the lever 44 up is limited by an abutment. At the top of the rod 41, a spring plate 50 (Fig. 9) is fixed, having a semicircular shape 51 on the right. With one turn of the nodes, a curved drum 11, along section 12, allows the rod 41 and the lever 44 to lift up. During the second revolution of the nodes, the drum / contact of the drum // and the string 41 stops.

At a distance of one meter below the nodes of the machine, there is a rotating disc chamber, with a charge of ten cobs of yarn. On disk 52 (FIG. 10), there are ten pin-holes 53, on which

cobs prt. The strand from the spare cob 54 (fig. 11) is thrown over the bar 55, then goes under the screw roller 56, covers the screw roller 57, and again, already on top, goes on the shaft 56; The ends of the sticks are clamped to the right of the screw roller 56. The feed screw rollers 56 and 57 (Fig. 12) have a large screw cut with a deep groove in which the threads from the cobs are laid. The right ends are giving; the screw rollers 56 and 57 are free and come up against the knot knot Y. The rim from the cob 58 unwinds upward between the clamps 59, 60 and 61, then goes through the bar 55 and the peephole 47 to wind it onto the reel. The transmission of movement from the nodes of the unit / to the feed screw rollers 56 and 57 is designed so that in two turns of the nodes of the host 1 the feed screw rollers 56 and 57 will make one turn. By rotating the feed screw rollers 56 and 57, the threads move to the knots.

The entire cycle of the work of associating a spare yarn with a triggered one takes place in two turns of knotted knots / around its axis. On the fixed rod 62 (Fig. 13), a locking hook 64 is seated on its finger 63, a pull spring 65 is fixed at its like end. There is an electromagnet bb opposite the left end of the hook 64, the ends of the winding 67 and 68 are included in a special circuit. When current is applied, the electromagnet attracts the hook 64, overcoming the resistance of the spring 65, and after the current supply is stopped, the hook 64, under the action of the same spring, returns to its original position. The stop 10, located at the bottom of the knots /, resting against the hook 64, delays the rotation of the jaw nodes and at the same time prevents it from falling down from the action 17. When the electromagnet 66 retracting the hook 64 is repeated, limited descent of the knots / down occurs at the time of contact with the hook 64. The hook 64 (Fig. 14) returns to its original position at this time and the stop 69 located on the flange 6 fits, and a new rotational delay occurs for the nodes 1, but the receiver itself is already in the bottom P position When the electric current is first supplied to the electromagnet 66 and the hook 64 is released, the anvil 69 is released, and the released unit 1 begins to rotate around its axis. The hook 64 is returned to its original position, as the current is applied to the electromagnet 66. The hook 64 fits under the screw rim 8 and the further rotation of the node assemblies /, due to the sliding of the rim 8 lo hook 64, forces it to stop up until the hook 64 rests against the stop 10. Stopping the node assemblies occurs after two turns around on its axis, which is one cycle of operation of the node nodes.

With a significant decrease in the cob diameter in the lower part, which occurs during the winding of the last yarn turns, the zimachs 70 and 7 / short before the yarn, wound to the normal diameter, are closed, and the first electric current passes through the electromagnet 66. The electrical current is supplied to the electromagnet 66 by the closure of the clamps 59, 60 and 61, which are previously separated by a thread moving between them. In this case, the second circuit of the electric circuit is carried out, the process of knotting of the knots takes place and the thread begins to go with the new full ear. Both closures act on an electromagnet located under the disk 52, and with the help of the ratchet gear and the pawl, they force the disk 52 to turn 1/10 of a circle, at the same time replacing the new cob with a new full ear.

During the operation of the device, two threads clamped on the knots of the shutter and going upwards, for one revolution of the knots, the locking knot will give one turn (the nerve turn of the knots of the locking unit makes it idle - without the strands, the second turn is given by the working stroke with the gripped threads).

The moving with and non-moving threads form a semi-crossroad near the nodes. Hook 24, when clamping the threads on the body of the knots, due to its particular shape, reinforces this semi-crossing of the threads until a half-turn is formed (Fig. 15). After clamping, the threads are hooked up to a vertical position, in which case one o6opoj knit knot occurs. The semi-turn is unwound, and then a new semi-turn of the reverse direction is twisted (Fig. 16). This half turn, moving upward, moves to the lever 44 - the thread goes to the eye 47, and the spare one goes to hook S. Thus, the threads coming from the knots at the bottom, forming the bottom of the half turn, are diverted in different directions, due to which friction between them is prevented.

Hook 24, having rods 27 and 28 when the customer pushes threads rotating around the nodes, arranges them in parallel (Fig. 17), so that they do not touch each other. The zigzag shape of the body of the knot knots allows the yarns running up along the knot axis with the hook 24 to be in the recess, and going over their loop does not affect or come into contact with the yarns laid in the recess (Fig. 18). The separation of the knot knot process into two parts makes it possible to produce knots in the course of a thread. The first part of the work consists in tightening the knots by the customer to take two threads - one moving, the other spare, and at the same time nowhere in contact with each other. When this occurs, the complete formation of the loop of the future node.

The second part of the operation of the device is reduced to pulling out the loop and forming a knot. The absence of obstacles to the movement of the loop along the nodes to the driver to its vertex makes it possible to form a loop from the loop within fractions of a second.

The modification of the device for tying the yarns (Fig. 19) is made in the form of a groove 72 with a block 73 fixed on it, which is integral with the sleeve 74. On the sleeve 74 there is a taper 75 reinforced, on the lower surface of which is a locking mechanism 76 regulating rotation of nodes stopped. Gutter 72 has a transverse incision 77 at the top (Fig. 20), from which a bend is made inside the gutter 72, forming a new gutter 78 of a smaller size. Both troughs have rounded edges. A chute 79 with a tail 80 is fixed to the chute 78 (Fig. 21) on the inner side. A window 81 is formed between the knife 79 and the notch 77, which is closed by a rod 82 which is integral with the spring 83. The right end of the spring 83 is fixed on the block 73 and the left 84 is free. When pressing from top to bottom on the end 84 npyj of the rail, the latter, lowering, will lower the rod 82 and open free access to the window 81. As soon as the pressure on the end 84 stops, the spring will take its upper normal position and the rod 82 will come out of the groove 72 and close the window 81, lukryva with its upper end of the lower sharp edge of the foot-knob 79.

The hook 85 sits loosely on the pin 86 and can rotate 90 ° on it. The long and thin spike 87 (Fig. 22) is intended to grip the main moving yarn. On the hook 85 (fig. 23), on the side, there is a finger 88, which is loosely attached to an earring 89, having a lower finger 90, on which the rod 91 is fitted with an eye 92. To keep the hook 85 in a vertical position under its lower cavity, it is connected with its vertical part 93 spring clip 94.

The lower branch 95, the spring of the strap of the bracket 94, is fixed on the block 73. The spring of the strap 94 rotates around the zinta 96. The rod 91. placed inside the block 73 and its bushings 74, with its end drawn below the bush 74 and has a double rim 97 at the end. The following occurs on pushing the double bezel 97: the rod 91 goes BHJJS and loses another 92, pressing the buckle 90 earrings 89, that is not the last one downwards. The hook 85, under the influence of the descending earring 89, rotates on the S6 stud, overcoming the resistance of the spring strap 94. When the hook 85 is turned 90 by 90, the spring strap 94 with its vertical part 93 presses the side surface of the hook 85, keeping the hook 85 in a horizontal plane. Alternating movement up and down of the earring 89 produces opening and closing of the hook 85, moving it from the vertical position to the horizontal and back. In the vertical position of the hook 85, its processes 87 and 98 enter window 99, which is located in the body of chute 72. When two hooks are hooked at 85 and then with one turn of the knot knots, the threads are screwed onto the knot nodes and occupy the position shown in FIG. 24. The two filaments are arranged in parallel, nowhere in contact with each other. From the shoots 87 and 98 of the hook S5, the threads turn up and go inside the loop, formed, thread, not in contact with them, because they are inside the groove 7

A rotating roller 100 is installed over the chute 72, along the entire mask, with a circumferential rotational speed equal to the linear speed of movement of the thread wound on a roller, spool, cartridge, etc. The roller-ball bearing 101 located obliquely opposite the roller 100 above each knot relative to the axis of the roller 100 (Fig. 25). The right portion 102 of the roller 101, representing a truncated cone, is in contact with the rotating roller 100, thereby rotating the roller 101.

On rewinders, windings and reed mashes, rewinding yarn and twisted thread from cartridges and bobbins, knotting units are installed against each drum or split rod. In the case of a triple YARN, two or three stacks are installed in the machine, respectively, two or three nodes are placed against each drum. The knots have a turning disk inside the machine, and the spare reels-cartridges with yarn of each Zzlov are installed.

The conical gear 75 (FIG. 26) rotates the conical bristle 103, and the rotation is transmitted through the 104 and 105 gears to the screw and to the roller 106, which has a deep thread, into which the threads from the disk, which are intended to be attached one after the other, are placed. as the next chuck draws - a reel on the disk. By rotating the platen 106, the filaments are gradually fed along the grooves to the knot. Spindle rollers 107 and 108, of the same device as spindle roller 106, receive rotation from scissors 104 through a row of scissors. In the left part, the screw rollers 106, 107 and 108 are fixed in the corresponding pins for each roller, and their right parts are free. The knots of the feeder under the action of the band tend to rotate, but this is prevented by the locking mechanism 76, whereby the band slides over the block.

When the yarn is pulled from the cob 109, the clamps coming together between themselves and 111 close the electrical circuit. Under the action of an electric current, an electromagnet 112 attracts a protrusion 113, which is located on the rod 114, and moves the wiper 114 to its upper position. The rod 114, ending at the bottom of the horizontal elastic plate 115, entering at the end of the double rim 97, gives sterA 8G5G1

zhen 91 up. Through the shackle 89, the double hook 85 from the horizontal position moves to the vertical and picks up two threads, the entrance with its S7 and 9S spikes into the window 99. Two threads going from the hook 85 upwards are inserted into the grooves 72 and 78.

On the rod 114, there is a side branch in the form of a short rod 116 ending in a square 117. By the time the rod 114 starts to move from the lower position to the upper, the square 117 rests on the part 118 of the locking mechanism 76. The square 117 moves the rod 114 from the lower position to the top, move up and uptrete into fork 119. Between fork 119 and stop 118 there is a notch-window 120. When square 117 rises against the notch-window 120, the delay of the hub units stops and it has the ability to rotate. After a 0.75 turn of the groove, square 117 appears above the end of the inclined fork 119 and slides but its vertical part, somewhat lifting. Continuing its rotation, the chute will make another 0.5 turn, and the square 117 will turn against the stop 121, and the nodes will stop, resting against the square 117.

The end of the spring 84 during the rotation of the spindle, meeting the corresponding stop, is pressed down, and the rod 82 is lowered down, opening the threads to the window 81 when tightening the threads on the nodes. The stop on the end of the spring then stops and the rod 82 returns up and takes up its normal position. After a 1.25 turn, the rod 82 takes up a position with the threads screwed onto it (Fig. 27).

10-20 seconds after the end of the yarn on the cob 109, the knot formation process takes place. The end of the thread from the cob 109, having passed the clamps 122 and 123, previously separated by a moving thread, will allow them to join. As a result, the electric circuit is closed and the electromagnet 124 does not rest down the rod 114. In this case, the wedge 125 of the rod 114 presses on the oblique wedge 126 and causes the holder 127 to deflect to the left on the axis 128, producing contact, the roller 101 with the roller 100. The axis of the roller 101 is located parallel to the axis of the shaft 100. Thereby the two threads are clamped in the rotating pair of the shaft 100 and the roller 101. In parallel, the moving thread is driven from a stationary state to the moving state of the spare thread. Further lowering down the rod 114 through the horizontal elastic plate 115 n double bezel 97 will move down the rod 91 and will rotate the double gripping hook 85 back 90 °. The threads are released and the loop of threads, no longer held up, slides freely upwards, no meeting of any obstacle. A loop node is formed over the nodes of the hitch.

When the rod 114 is further lowered down, between the upper end of its 129 and the elastic plate 130, the two ends of the threads to be cut will be clamped and the movement of these threads will stop. The movement of the left ends of the threads, under the action of rollers 100 and 101, forming a loop-knot t is not up, and the knife 79 cuts the bottom loop. From the knot that has formed, the trimmed and clamped right ends of the threads pop out. The knot is ejected over the rollers 100 and 101 and followed by an attached new thread; roller 101 is deflected to the right.

At the beginning of the downward movement of the rod 114, the square 117 was against the recess-window 131 formed between the plug 7/9 and the stop 121. The square 117 freely goes down through the recess-window 131 and, having reached the lower position, together with the rod 114, stops. After knocking down the square 117 downwards, the nodes begin to rotate unhindered and make 0.75 turns until the stop 118 is pressed against the square 117.

After 0.75 turn of the knots, the hopper with the hook open, folded back under the successive threads, is in its original position.

Due to the special arrangement of the locking mechanism 76, the nodes rotate: the first period with the captured yarns 1.25 turns; the second period - with the hook hooked back 85 to 0.75 turnover.

The entire cycle of knots of knots occurs in two turns of knots.

To hold the rod JJ4 in extreme positions, on the side of the rod 1M there is a bar 132 with two semicircular grooves 33 and 134. The groove includes a roller 135. On the axis 136 which presses the plate spring. The roller 135 when lowering and raising the rod IM alternately enters the recesses 133 and 134 and holds the rod in the desired position.

Two threads, which are clamped on the knot knots and going up in one turn of the knot knots, will give one turn of yarn. Two threads behind the nodes of the user form an intersection (Fig. 28), a half-turn of the opposite direction. After clamping the threads on the knots, a 1.25 turn of the chute occurs. The semi-turn is unwound and then a new semi-turn of the reverse direction is twisted. The threads going upward from the knots are diverted in different directions, which prevents friction between them.

The division of the process of knots into two parts, as in the main knot of the customer, makes it possible to produce knots along the thread. The third part of the work consists in tightening the knots by the customer for two or two seconds on two threads - one operated by the moving one, the other by the spare and at the same time never touching each other. There is a complete formation of the loop of the future node.

The second part of the work, separated from the first 10-20 seconds, is reduced to pulling out the loop and forming a knot. Since there are no obstacles to the movement of the loop along the nodes of the gateway to its vertex, the loop freely slides upwards, and this makes it possible to form a loop from the loop within fractions of a second. This is the second part of the work and allows you to produce knots along the thread.
