SU99996A1 - Device for signaling the presence of metal objects woven into the fabric - Google Patents

Description

The subject of the invention is a device for signaling the presence of Cesc objects woven into metal with two metal rollers, between which the fabric is drawn. The rollers are included in the signal circuit of the control unit, which is automatically closed by the ends of a metallic object protruding from both sides of the fabric.

The advantage of the proposed device in comparison with a similar analogue device device for the same purpose is that it provides a signal also in the case of a metal object on one side of the fabric.

This is achieved by the fact that two pairs of plate electrodes are included in the circuit of the circuit; or control.

FIG. 1 shows a general scheme of the device; FIG. 2nd basic electrical circuit.

The device mounted on the bracket in front of the finishing roller consists of two metal rollers / and 2, horizontally ODIH above the other, and two pairs of plastic electrodes 5 installed along the path of movement of the tested fabric 4 on both sides. The rollers and e, 1ectrode are included in the electrical circuit of the control signal.

The electric circuit of the device includes a magnetic starter 5 of the engine 6 finishing roller, magnetic actuator control buttons 7, a sensitive intermediate or TOKOiBoe relay 8 with normally closed contacts, a transformer 9 with a secondary winding voltage of 24 V, a plug socket W with a plug for disconnecting the device if it is damaged, and single-pole switches 11 for disconnecting the plate electrodes 3 or metal rollers 1 and 2 for I1X damage.

The fabric 4 is passed between the wafers ./ and 2 and proceeds further to the finishing roller, in contact on the path of the CBoeriQ, with both, and with their sides, with plinth-mn electrodes 3.

In the presence of metal objects woven into the fabric with ends 1-G1 protruding from both sides

t: Kani, these ends automatically close the electrical circuit through the terminals, as a result of which an impulse is given to relay 8, iKOTOpoe opens the normally closed cankits turned on in the control (no magnetic iuskate. 5 w the finishing roller 6 turns off and stops .

If the protrusion of the 11th end of the woven metal fabric is found: the TC is only on one side of it, then the electrical closure does not occur when the rollers 1 and 2 pass through, but when the protrusion of the horse: the metal metal object, but only the plate electrodes 3, with the result that a signal is given to shut off the engine 6 of the precision roller.

TaiKHiM way, in all cases la.JJ in the fabric woven into it meta.;, (Ical items of the engine 6 otdel.nog) roller is turned off.

PRIORITY AREA

A device for signaling aa. LCDs of MCs are woven into cloth, consisting of two metal rollers, between which a cloth is drawn and which are connected to the signal circuit and are automatically locked by pushing from both sides of the fabric. ends of the metal object that is woven into it, which is 1d e so that, in order to give a signal, even if there is a metal object on the one side, the movement of the fabric on both its sides is set .thenes two pairs of plasticity () electrodes included and the signal circuit tchi councils "tstsi.
