    Continuously cast plastic strip has interspaced marks or defects with lengths of unmarked usable strip therebetween. To obtain a maximum possible yield of sheets from such strip, the lengths of the portions between the marks or defects are measured and cut into sheets of two or more different lengths, the cutting being such as to produce the maximum yield of sheets of either or all lengths, singly or in combination, which can be obtained from the length cut. This procedure reduces the loss or waste due to the marks or defects, to a minimum. A special system is provided for this practice and for cutting out the marks or defects between the unmarked strip portions free from defects, with a minimum of loss or waste. Other features are involved.

    the device for measuring the length, the device for detecting no defect and the device d: & 1 presetting for a given length of sheets. Connected to the input of the computing device, the output of which is connected to the device for cross-cutting of the material.
    The method is carried out as follows, I
    When cutting a moving strip of sheet material into pieces, when it is necessary to obtain two or more types of sheets of relatively long and relatively short, measure the length of each suitable strip of sheet material. Then count the number of sheets of various predetermined length, which can be cut off from each quality section of the strip of material, and give a signal to the cutting operation.
    As a result, the loss is reduced, which is defined as the remaining part of the lic: that formed after cutting the corresponding number of sheets of two or more distinguished lengths from suitable sheet sections, Output of sheets of the first grade, which can be obtained from the strip of material between the places defects, with respect to the amount of waste, the material bands increase, and the cost of the product decreases. . ,
    The drawing shows a block diagram of the proposed system for carrying out the method.
    The control system for cutting sheets of various lengths includes tools 1,2 and 3 for measuring leytochny material, tools 4 and 5 for determining the location of defects on tape material, each of which is an electric sensor, 3 electronic or photoelectric type, electronic computing device (computer ) b, prisg (feature 7 for presetting the system on sheets of a given линыlin, counters 8, 9 and 10, regulator 11 of the cutting machine двиг s 12 engine 12. Cutting device including There are upper and rifle circular saws 13 and 14 fixed to the shaft of engines (not shown) mounted on a carriage 15 moving in the transverse direction on the frame 16 resting on the fixed beds 17 and 18 on which it performs returnable access. parallel to the direction of movement of the strip 19 of tape material.
    In each of the counters 8, 9, and 10, tfeiTb may be preliminarily laid in a number representing the length of the sheet cut from the moving strip 19 of the tape material. Three
    the counter 8.9 and 10 continuously and simultaneously count the electric pulses coming from the sensor of the device 3. Each of the counters 8, 9, 10 is set to zero when the number of counted pulses reaches the number previously installed in each of the counters, n; From the counters, counts the electrical pulses coming from the sensor of the device 3. In the computer system 6, the OV counter is connected to the controller 20, so that the computer can choose any of the counters 8, 9 and 10. Thus, when the selected counter is reads a predetermined number of electric pulses from the sensor of the device 3, the regulator 20 supplies the regulator 11 of the pulse motor 12 with a start signal. At the same time, the selected counter 8, 9 or 10 is set to zero. Counters 8, 9 and 10 are connected in controller 20, as a result of which, upon completion of the reading, a specified number of electrical pulses and the selected counter are set to zero, the remaining dB from the meter immediately stop counting and these are set to zero.
    When the controller receives a signal from the controller 3
    Start
    the controller applies electrical pulses to the pulse motor 12. Fe as a result of this, the frame 16 begins to move in the same direction and synchronously with the speed of movement of the strip 19 of the tape material. The controller 21 starts monitoring the cutting with the cutting device after it receives a signal indicating that the controller 11 is activated by the pulse engine 12, i.e. As soon as the frame 16 starts to move, the controller 21 controls the sequence of operations t, e, by clamping the moving strip 19 of the leNtrn material by moving the saws 13 and 14, cutting the strip 19 of the tape material, and releasing the clamped strip 19 by withdrawing the saws 13 and 14 from each other. When the strip 19 is cut across with the saws 13 and 14, the movement of the frame 16 is synchronized with the movement of the strip both in speed and in voltage. This synchronization is achieved by the fact that the sensor of the device 3, similar to the sensor of the device 1, sends pulses to the pulse motor 12. Upon completion of the cutting, the regulator 21 iodizes the feedback signal to the controller 11. Under the action of this signal, the pulse motor 12 temporarily stops to reverse it and then re-actuated, returning the frames 16 to their original position. Simultaneously with the frame-16, the carriage 15 returns to its original position, carrying the cutting saws 13 and 14, the cutting cycle ends. Next, the cutting process is repeated.
    When one cutting cycle is completed from regulating the mouth 21 to the controller 11 and the computer 6 is given a feedback signal, the computer 6 then sends to the controller 20 a counter selection signal, by means of which one of the counters 8, 9, 10 is selected, capable of representing the length sheet, subsequently cut from the moving strip 19 of the tape material.
    When the output signal from the sensor of the device 4 or 5 to determine the location of the defect on the tape material arrives at the computer 6, the location of the defect Ma of the moving strips
    19confirmed by comparing the current signal from the sensor device 4 or 5 with the output signal
    from the sensor of the device 1. In the case when there is no defect between the confirmed position of the defect site and the strip section approaching the cutting device, the computer 6 calculates in which combined ratio the sheets of three installed different lengths embedded in the counters 8, 9, 10 can give the total combined length that is closest to the length of the area between the defect indicated by the Site and the strip of tape material approaching the cutting device or that has just been cut off with a sheet of material, reducing its loss, which is formed when a sheet is cut from a suitable section of the strip of tape material in the established combination. After that, the resulting combined ratio for a suitable section of the strip of tape material is laid in the memory of the computer 6,
    On the basis of this, the computer stored in the memory 6 of the combined ratio of computers delivers to the controller
    20 consecutive counter selection signals, indicating which of the counters 8, 9 and 10, containing a number representing the length of the sheet to be cut from the moving strip 19 of the tape material, should be selected at each successive counter select signal. When these signals arrive, the tape material is cut into sheets of various lengths.
    in the calculated combination of their ratio.
    In case there is a defect between the confirmed defect area and the strip section reaching the cutting device, the computer B produces
    a calculation similar to that described. The results obtained are stored in the computer memory. Then, on the basis of this data, the computer b sends the selection signals to the controller 20, as a result of which a suitable section of tape material is cut. -, .- -. ; ,
    In case the defective area on the moving material strip 19 exceeds the length of any strip length embedded in counters 8, 9 and 10, two of these three counters are used to preliminarily set the length of sheets going to the product, and third counter
    5 serves to set in it a number representing the appropriate length of the sheet into which the defect area is to be cut. Cut sheets of material containing defects go
    0 to waste.
    The computer b may send a signal directly to the controller 11 for cutting the strip 19 of the tape material. This allows the strip to be cut.
    5 cutting device immediately after the defective section of the tape material, confirmed by the DELECT COMPUTER 6, passes underneath it. :
    So about | 1bm, from a suitable tape material, the ryo onseynogo for
    0 defective area of it, cut the sheets of the first grade, and the output of such sheets is gained
    When the signal from the computer 6 is fed directly to the controller 11,
    5 counters 8, 9 and 10 are set to zero .. -.
    The proposed system optimizes the process of cutting - sheet material into sheets of different lengths, ensuring, in the presence of defects in the material, the choice of several lengths of sheets from one quality section of the material, which reduces its waste.
