Abstract

This invention relates to controls and can be used on textile machines. The purpose of the invention is the expansion of technological capabilities. The braiding thread, winding off the package and passing through the thread guide system, twists the roving and wraps around the package. When the braiding thread is torn off, the lever of the breaker of the braiding yarn with its magnet closes the reed switch, which turns on the magnetic holder and simultaneously activates the stop mechanism of the roving frame. 3 il.

Description

This invention relates to controls and can be used on textile machines.

The purpose of the invention is the expansion of technological capabilities.

Fig. 1 shows a diagram of installation of the device on a textile machine ;, Fig. 2 shows an electrical circuit of the device; on fig.Z - breaker interlacing yarn sensor.

The device contains a bundle 2 fastened on frame 1, braiding thread 3, pegs 4 for adjusting the thread tension in the monitoring area of sensor 5 for breaking the braiding thread, thread guide 6, lever 7 for moving magnet 8, tension roller 9 for tensioning the braiding thread 3, the rolling roller 10, which regulates the flat movement of the thread, the guide rod 11 for distributing the direction of the horizontal movement of the thread depending on the position of the selected spindle and the spindle 12, which serves to align the roving 13 with the braiding thread 3,

In addition, the device contains a reed switch 14 sensor 15 break rovings 13, the outputs of which are connected to the elements of the actuator 16 stop roving frame. The interlacing yarn break sensor 5 has a reed switch 17 connected with an indicator 18, a magnetic holder 19 and through a diode 20 with a reed switch 14 of the roving break sensor 15, and a relay 21 of the actuator of the roving frame stop mechanism 16, the closure contacts 22 and 23 of which are used in diagram of the magnetic starter roving machine (not shown). Relay 21 is powered by a DC source 24.

The device works as follows.

The braiding thread 3, unwrapped from j of package 2, pass through pegs 4, nor "

the heatconductor 6, the lever 7, the tension roller 9 and the rolling roller 10 along the guide rod 11 are wound with a twisted braiding thread 13 on the packing of the spindle 12.

When twisting, the braiding thread is tensioned in such a way that it provides a vertical position of the lever 7.

In the absence of a signal at the output of the reed switch 17, the control circuit of the diode 20 serving as a locking element in the circuit is de-energized, thereby disconnecting the circuits

a relay 21, an indicator 1o and a magnetic holder 19 for holding the magnet 8 in the extreme position. In this case, the technological process of twisting the thread 3 with roving 13 proceeds in the specified modes

When the twining yarn 3 breaks, lever 7 takes a horizontal position and with its magnet 8 closes the contact of the reed switch 17, a signal appears at its output that switches on the magnetic holder 19 to hold the magnet 8 of the lever 7. The fault indicator 19 turns on sections and numbers of the workplace.

In addition, the signal from the output of the reed switch 17 (FIG. 2) also goes to the input of the diode 20 connected in the forward direction with the input of the relay 21, which

with its pins 22 and 23 it sends a signal to the machine control circuit.

When the roving 13 breaks, the reed switch 14 is activated and switches the signal with its contact, thereby ensuring the switching on of the relay 21 and subsequent circuit elements of the actuator 16 of the roving frame.
