(54) DEVICE FOR AUTOMATIC JOB AND CONTROL OF PRODUCT DEFORMATION

and the measuring circuit with the OJIOJICM U task and the block 11 of the Be / Shchkn111 deformation, as well as measure the value of the recorder 12.

The device works in the following way.

At the registrar 12 set the value: ;; product extension, customizable -: -. The pressure cap is set;); the pressure corresponding to the strain of the product, after which the stretch grinder is turned on. When installing the product 3 into the clips of the heads of the stretching machine with the sensor 4, the adder 8 receives a signal; proportional to the initial length of the product 3.

When the flow head is moved by the amount required for sampling the elevators, compensating for the slack, straightening within elastic deformation, a signal appears at the output of the sensor 5. Which through the electronic memory block 7 goes to the adder 8. This signal is summed with sensor 4, makes a correction of the signal of the initial length of the product 3. As a result, the signal to the block 1O receives a signal proportional to the actual length of the stretchable product 3. As it turns out; - Kg; 13th movement of the stretch g. finished, pressure sensor b 6 will start to increase and the signal from it will trigger the electronic block 7 of the memory, concluding in fixing the magnitude of the signal sent at this moment by the sensor 5 to the electronic block 7 of the memory. having the same polarity as the .I signal from sensor 4, and the opposite polarity with respect to the signal continuing to come from sensor S. The adder 8 outputs to the block a 10-signal from the electronic memory unit 7 and sensor 4 proportional to the actual for; -1 not preformed from after eating at the pyr second gfavky.

Sum 1X p 9 K.iuEaer on block 11 we fill. signal, pro, orschopal difference between the magnitude of the current displacement of the tensile head and the vepchnik of the displacement of the extensor head in a stage of elastic straightening. In connection with the pro; i1, 1; ms: 1; By moving the stretch head, the signal from sensor 5 grows, which causes an increase in the magnitude of the signal with adder 9, and this, in turn, causes a current to appear in the measuring circuit that is proportional to the amount of deformation of the product.

As soon as the amount of deformation reaches a predetermined value, the measuring device 12 turns off the movement of the tension head 2, which brings the electronic memory module to the initial state. The implementation of the device with the use of an electronic memory unit made it possible to increase its speed, as well as to improve the measurement accuracy by eliminating contact mechanical elements from the circuit.
