SU143196A1 - Adaptation to spinning machines of synthetic fiber to stop spinning when thread breaks - Google Patents

Description

Spinning gears for stopping I are known.

springs with a breakage of the thread, including an unbalanced lever, g

interacting with one arm with a thread and the other with electrocontact j

actuator, stopping prdie.

The described device contributes to the reduction of waste when using synthetic fiber machines on machines and improves the performance of spinning machines. This is achieved by the fact that an electric relay, including electrical audio signaling, and an electromagnet, which turns off the remote pump, is used as an actuator, when winding the filament on the feed roller.

The drawing shows a general, 1 scheme of the design for spinning machines to stop the spinning when the thread is broken.

The device consists of the main components: the control mechanism / and the executing mechanism //.

The control mechanism includes an unbalanced two-arm lever /, one shoulder 2 of which operates with the thread 3, bending the roller 4 and the other shoulder 5, through the ball system) of the common bars and levers |

6-7-8 associated with electrocontact 9 nspoli- tating mechanism //.

The actuator is embodied in the form of an electrical circuit, including an electrical switch W with connected to it: electric calls // - Pa. signal lamps 2- / 2a and a solenoid f3, interacting with a double-arm lever / 4. which controls the switching on and off of the dosage control unit 15;

The work of the device is carried out as follows, (

If the thread breaks, its end is wound on a roller 4.I

Leaning on the roller 4, the arm 2 levers / is pressed due to |

this is away from the roller 4 and includes through the levers 6-7-8 contact 9.d No. 14319G- .- 2 - -. . When the pin 9 is turned on, the current passes through the wire J6 through the normally closed contact J7 of the relay 10, through the primary circuit J8, through the normally closed contact of button 19, to the electromagnet 13, which uses the lever J4 to activate the metering pump / 5. At the same time, the voltage goes through the wire 20 to the bell // and the signal lamp 12, which are located in the filling part of the machine, and along the wire 2J to the signal lamp 12a located in the winding part of the machine. Upon detecting the signal, the foreman-pumper pushes button 19 and, filling the workplace, turns on the metering pump 15. Pressing button 19 opens the primary circuit 18 and activates the secondary circuit 22. Relay / (3 operates, opens normally closed contact 17 and closes contact 23. At the same time, the current through the wires 24, 25 and 21 is sent to the w / c call and the signal lamp} 2a, located in the winding section of the winding machine. There is a place to go to work. in the thread on the splitter 26, it presses the button 27 and turns off the relay 10. The circuit is reset to its original position, i.e. the primary circuit 18 is switched on in the power supply circuit. Correcting masks will reduce the amount of nylon fiber waste, since the pressure pumps will be rejected immediately after the thread breaks and, thanks to the alarm, the operator can quickly take measures. In addition, machine maintenance is facilitated, especially if thread breakage occurs in several places. npeArjT of the Invention An adaptation to synthetic fiber spraying for stopping a yarn when a thread breaks, including an unbalanced lever that interacts one arm with the thread and the other with an electric actuator contact, characterized in that, in order to reduce the amount of waste during spinning and to increase machine productivity , an electric switch was used as an actuator, which included electric and light alarms and an electromagnet that turned off the spinning pump when winding the thread on the roller of the feeding device.
