Description

HsEiQCTHbi Adaptations, for example, to the foundations of a filling machine for turning it off when a thread breaks, made in the form of contacts placed under the warp, included in a relay circuit that turns off the machine's drive, and which are closed by a broken thread that is carried along by the drive pick-up device.

The described device has the difference that, in order to increase the reliability of turning off the machine, the contacts are made in the form of the free end facing the base of the file, and the exciting thread is in the form of a comb located along the line of the contact party in the reciprocating motion drive and mashine drying; to seize the torn thread and blow it at one of the contact tails.

In order to protect the contact profile from dust and damage, a casing is pivotally mounted above them and the base.

FIG. 1 shows a device, side view; in fig. 2 is a section on AA in FIG. one; in fig. 3 wiring diagram.

Under each of the bases / (Fig. 2) of the foundations of the needle-making machine, the described device is installed, consisting of contacts, a drive device that captures a dangling thread, and a relay circuit. The device is mounted on a grounded conductor of the play tube 2 (Fig. 1, 2 and 3), located under a controlled base. The pipe is made with holes at an equal distance from each other (for example, 30 mm), in which screws 3 and 4 are located, insulated from the pipe by tabs 5 and b of a dielectric. On axis 7, light conductive tubes 8 are installed, held vertically by weights 9.

All center screws 3 are connected by a common wire 10 connected to the input of an electronic relay, and the pipe and the pendulum are contacts that, when the peg is in contact with the tube, this relay.

The gripping dangling yarns of the device are made in the form of a comb 11, guided by the strips 12 and driven back and forth from the drive of the machine - along the arrow B by means of a lever-cam gear (“not shown in the drawing). A torn comb, a broken thread of the warp strikes the tandem 8, causing it to touch the pipe 2.

The relay circuit has electronic relays on the thyratrons 13 (Fig. 3) according to the number of monitored bases (two relays are shown in the drawing), to the inputs of which are connected contacts consisting of a pipe 2 and a connector 8. To the output of each relay there is a neon signal light 14 and a common electromagnetic relay 15, equipped with normally-closed contacts, connected in series to the circuit of the contact stop button, switching off the drive electrode of the machine through the magnetic actuator 16 (the stop button, the relay contacts and the electric motor the diagram is not shown).

The power supply of the electrical circuit is carried out from the alternating current network | With a voltage of, for example, 220 V through a transformer 17 and an expander on a kenotron 18.

For puka electric motor and bringing the circuit to its original state in the power circuit of the anodes of the relay on the thyratrons included start button 19, breaking the circuit and at the same time closing circuit of the magnetic actuator 16, including the drive motor.

With the goal of protecting contact ticks from dust and damage, the hell HHiMH and the base / (Fig. 2) are flip-flop on O-20, a cover 21 is installed.

The action of the device is as follows. If one of the warp threads breaks / this thread falls onto the comb 11, is caught by its teeth and strikes one of the models 8. The insert touches the pipe 2, including the corresponding thyratron 13 of the relay. When a thyratron is ignited, a corresponding neon light 14 is turned on, indicating a break in the filament in one of the two Seines. At the same time, the electromagnetic relay 15 is turned on, breaking the circuit of the magnetic actuator 16 with its contacts. The magnetic starter turns off the drive motor of the machine.

To restart the machine after the elimination of a thread break, press the button 19, breaking the anode circuit of the thyratrons, returning them to the initial extinguished state, and turning on the magnetic starter 16, which starts the electrodes and the heaters.
