A recess 18 with a protrusion 19 is made on the surface of the bar that faces the rod 15. The rod 15 has the ability to move by means of the spring 17 in the direction of the station The voltage 15 contains an electromagnet 20 with a bark 21 and a switch 22 connected by a cable 23 through a plug 24 through a time relay 25 to a feed control unit 26 to the section 27 and fibers of the machine Plank 10 is installed on the side of the electromagnet core 21, and the fixing unit has two shoulders a lever 28 placed between the bar and the electro magnet and pressed by one shoulder by means of a spring 29 to the electromagnet bark, and the other arm -i to the stop 11 of the bar; which is located in the cover cap 2.. The housing 1 is fitted with a switch-on control lever 30 of a switch 22 electrically connected to a time relay 25 and a control unit 26. The time switch has a fuse made, for example, connected to a spring control lever 30. With enough force to turn the switch on. It is possible to carry out the displacement of the rod 15 instead of a notch with a protrusion on the strip 10 using an additional electromagnet associated with a time relay 25 (not shown). Springs 12, 17 and 29 can be replaced by pneumatic or hydraulic power elements. A variant of the fuse is possible in the form of a second time relay 31 controlling the operation of the switch 22 (FIG. 6). The plug 24 has three contacts 32-34. A capacitor 35 and a resistance 36 are connected in series with the contacts 37 and 34 with which the switch 37 is connected. connected to pin 32, a capacitor 35 and a resistance 36 are connected in series with a resistance 38, a semiconductor Zener diode charger and a transistor 40. A relay 41 is placed in the emitter circuit of the transistor connected to pin 32, and the collector is connected to pin 34, Re E 41 serves to turn on the switch 22, having two contacts 42 and 43, connected on the same side with contact 32. On the other side, contact 43 is connected to contact 33, and a capacitor 44 is connected in parallel with Contact 42. Resistance 45 is connected in series 42, semiconductor Zener diode 46 and transistor 47 (whose collector, through resistance 48, is connected to the control electrode of the thyristor 49, the thyristor 49 is located in the power supply circuit of the electromagnet 20, to quench the thyristor when the current supply to its control transition is interrupted A diode 50 connected in parallel with an electromagnet 20 was installed. The plug socket 51 of the control unit 26 contains a switch 52 connecting the conductors between contacts 32 and 33 and having a mechanical switching element 53 controlled by a plug 24. Outputs 54 and 55 of the socket 51 are connected to the machine thread monitor 56 The output 54 is connected to the conductor leading to the contact 32, and the output 55 is connected to the output 57 connected to the power line to which the output 58 is connected. The output 58 is connected to the conductor leading to the contact 34 and with exit 59 leading to The electromagnet 60 of the control unit 26, and the output 61 is connected to a conductor leading to the contact 33. The observer 56 has a contact 62 connected to the rotary lever 63 of the nitro detector. During the operation of the machine, the fiber tape 64 coming into separation 27 is divided into separate waves, from which a yarn 9 is formed in the spin chamber 65 and twisted 9. The straps 66 are taken out of the chamber from the chamber, at the exit of which the observer 56 is installed. and is wound on T, driven into rotation by the friction cylinder 8, wherein the switch 52 is closed and the outputs 54 and 55 are connected to one another. Under normal tension, the yarn contact 62 of the nitro 56 is open, so that the circuit of the electromagnet 60 is interrupted. When the yarn is broken, the contact 62 closes, a voltage is applied to the electromagnet 60, and the supply of the fiber tape to the separation unit is stopped. A light bulb 67, mounted on frame 3 and connected parallel to the electromagnet 60, lights up. In order to implement yarn pinning to the fibers in spinning chamber 65 after its breaking, or stopping, the machines are lifted by the handle 68 of the packer carrier packs. The housing 1 of the device is mounted on the machine 3 on the right-hand side of the package (Fig. 5) and the hook 4 and the spring 6 are fixed on the frame to facilitate installation of the case in the desired position. a special mark is made on the paiMe. Then, the stop 11 protruding from the cover 2 extends the bar 10 from the housing and is located under the package 7. The lever 28 is then pushed back by the spring 29 and the end of its shoulder rests on the stop 11, fixing the extended position slats 10. When the strap moves under the package, the core 15 pressed against it by the protrusion 13 extends from the sleeve 16, overcoming the spring force 17. Next to the end found on the package, the yarn is wound from the package by the length indicated by the mark 69 on the split assembly body 70 , and - on the bar 10 lower packs ku The sticks are inserted into the spin chamber tube 74 and a rod 15 is pulled onto the lip of sleeve 16, forming a backup loop (Fig. I). The plug 24 installed in the socket 51 of the control unit 26 by means of the switching element 53 opens the switch 52, whereby the contact 43 of the switch 22 bridges the switch 52 and the electromagnet 60 receives voltage through output 57, contact 62, output 54, contacts 32, 43 and 33 and the outputs 61, 59 and 58. Since the contact 62 of the nitron is closed, the light 67 remains B5. When turning the control lever 30, it acts on the switch 37, as a result of which the / capacitor 35 starts to charge (Fig. 6). If an erroneous switching on of the bodies 37 occurs, at which it is quickly relieved by the action of the control lever 30, the semiconductor Zener diode 39 does not reach the switching threshold, the transistor 40 does not energize the relay 41, and the capacitor is discharged through the switch 37. With a long when the lever 30 is applied to the switch 37, the capacitor is charged until it reaches the threshold for turning on the semiconductor stabilizer 39, the transistor goes to the open state, the relay 41 is energized and the contacts 42 and 43 are switched off. As a result, the electromagnet 60 is turned off and the supply of the fiber tape to the separation unit and, accordingly, of the fibers to the remote KciMepy is restored (Fig. 1). When opening the contact 42, the capacitor 44 is charged, the speed of the arc is determined by the position of the potentiometer 71. After reaching the threshold for turning on the Zener diode 46 to the tra, electromagnetite 20 is energized and the thyristor 49 is energized and as a result, the electromagnet 20 is energized At the same time, the measles 21 rotates the lever 28, frees up the stop 11, and the bar 10-spring 6th 12 moves to the body 1 and returns to its original position. The package 7 under the action of its own weight is lowered onto the friction cylinder 8. Simultaneously with the movement of the strip 10, the end of the rod 15 appears in its recess, retracted by the spring 17 into the sleeve 16. This leads to the fact that the yarn under the action of suction the chamber is sucked in it and is knocked out to the fibrous ring formed at this point in the chamber. Under the tension of the yarn attached, the contact 62 of the nitro 56 is opened, and the light 67 is extinguished, and the yarn itself is inserted into the thread guides 72 and 73, by diverting rollers 66 out of the chamber and wound onto a rotating package. When housing 1 is removed from frame 3, switch 52 is closed again. To place the end of the yarn at a predetermined level relative to the spinning chamber, it is possible to use means for cutting the yarn. It is possible to connect the device to the mains through the contact bus and brushes or to connect it to the control unit with a plug located directly on the housing. Adjusting the dwell time of the relay 25 can be accomplished by performing a capacitor 44 with a variable capacitance and using conventional resistance instead of potentiometer 71. In the absence of a fuse in the form of an adjustable time relay 31, both pins 42 and 43 of the switch 22 are actuated. directly from the control lever 30. Claims 1. A device for picking yarn on a ringless spinning machine with a fiber control unit, comprising means for removing the package from the friction cylinder of the machine, connected to the element to form a backup yarn loop, and (a magnet connected to the control unit of the machine, which is due to the fact that, in order to ensure the universality of the device, it contains the housing mounted on the frame of the machine by means of a fixation device, and retraction of the package and the element to form a backup loop are mounted in the housing with the ability to move in mutually perpendicular directions by means of elastic elements, while the electromagnet of the fixation unit has a switch and is connected to the machine control unit via a plug via a time relay.
