The disadvantage of this machine is the impossibility of obtaining information about the actual width of the workpiece, since it does not incorporate a device that measures the width of the workpiece obtained as a result of cutting.

The purpose of the invention is to increase the efficiency of quality control of the meter and expand the functionality of the machine.

5 The goal is achieved by the fact that a diagonal cutting machine containing a conveyor with a drive for supplying tape material, a diagonal with a cutting carriage, an automatic measuring device with a control ruler and photo sensors is additionally equipped with a second ruler mounted on the frame of the conveyor with the possibility of vertical alternation, and installed on it a sensor of the actual width of the workpiece, as well as an information processing unit. At the same time, the sensor of the actual width of the workpiece consists of an opaque casing, two photoelectric cells adjacently located inside the casing on the board successively in the direction of movement of the material of the workpieces, a vertically movable lens reinforced in the casing bottom under the photoelectric cells so that its optical axis passes through the plane of contact of the photoelectric cells and perpendicular to the plane of the conveyor, the illuminator attached to the outer surface of the bottom of the casing and lining of sheet material with high light reflectance this ability, which overlaps the field of view of the lens and is attached at one end to the sensor housing, to move the workpiece tape through it. In addition, the information processing unit consists of a logic device, a device for displaying the actual width of the workpiece, counters for workpieces More, Less General, an arithmetic device for calculating the scrap rate, an indicator device for the scrap rate and an audible alarm, the first and second outputs of the actual width sensor are connected respectively to the first and second inputs of the logic device, the first output of which is connected to the input of the indication device and the actual width of the workpiece, the second output - from the input ohm counter More, the third output - with the counter input Less than the fourth output - with the counter input General, the counter outputs are connected respectively to the first, second and third inputs of the arithmetic unit, the first output of which is connected to the input of the indg-1 locking device of the reject rate, the second output - with sound alarm input. Thanks to the use of the proposed machine, it is possible to automatically control the width of each blank, to obtain operational information about the quality of the measuring device, which leads to the exclusion of the receipt of defective blanks for further operations. FIG. Figure 1 shows the layout of the sensors of the metering device and the actual width of the workpiece on the diagonal cutting machine, side view; in fig. 2 the same, top view; in fig. 3-5 the device for fastening the sensor of actual width and reflecting side, side, top and front view; in fig. 6 and 7 show the actual width sensor design, side view and front view; in fig. 8 is a block diagram of the proposed device; FIG. 9 is a diagram of the workpiece sensor of the actual width of the workpiece. The diagonal cutting machine comprises a conveyor 1, on which a cut rubber-cord material 2 is located, a diagonal 3 with a cutting carriage 4, a photosensor 5 for converting the conveyor to a reduced speed and a photosensor 6 for stopping the conveyor. The photo sensors are mounted on a ruler 7 mounted on the frame of the conveyor 8. The second ruler 9 through carriages 10 is connected to the uprights 11 mounted on the conveyor frame opposite the ruler 7. The sensor 12 of the actual width of the workpiece is connected to the ruler by carriage 13, and the lining 14 is reflective surface mounted on the sensor housing. Two photocells 15 and 16 of the actual width sensor are located on the board 17 and are mounted in an opaque housing 18 along the center of the lens 19, the illuminator 20 is fixed on the bottom of the sensor housing. Racks 11 are marked with risks 21, the position of which corresponds to different widths of the controlled tolerance floor. The actual width sensor outputs are connected via a logic device 22 to the device 23, indicating the actual width of the workpiece, workpiece counters greater than 24, Less than 25, Rang 26, and when the latter are connected through the arithmetic device 27 to the reject percentage indicator 28 and the acoustic alarm device 29. The device works as follows in a way. Before work, adjust the actual width sensor. The predetermined width of the cut-off is set by moving the carriage 13 along the ruler 9 and fixing it in a predetermined position. The specified value of the controlled tolerance field is established by moving the carriages 10 and, consequently, the sensor 12 in the vertical direction along the posts 11 and changing the distance between the photo cells 15 and 16 and the lens 19 by moving the latter. The movements of the carriages 10 and the lens 19 are made according to the risks 21. The carriages 10 are fixed in the desired polishing with latches. Solar cells 15 and 16 have a width w, / 2 each. Change the height H ;. (from photocells 15 and 16 d of workpiece 2) and b (from photo cells 15 and 16 to lens 9}, change the magnification of the optical system, i.e. the same value in, correspond to different sizes m thereby setting The actual width of the sensor to different tolerance fields equal to the value of No. 2 / 2. The electrical circuit of the sensor is adjusted so that even partial illumination of the photocells 15 and 16 results in a logical 1 signal on its outputs. Photocell 16 is the main one: its optical position axes correspond t the position of the edge of the workpiece with a nominal size, and the boundaries of its field of view correspond to the workpieces with the minimum and maximum allowable width. until the front edge crosses the beam of the photo sensor 5, then the conveyor moves to a reduced speed and the cord edge crosses the beam of the photo of the sensor 6. When this sensor is triggered In this case, the conveyor 1 is stopped. The measurement is made after the conveyor 1 is stopped. There are three possible positions of the cord edge relative to the specified tolerance field. 1. The log has a predetermined width. In this case, the edge of the workpiece is within the limits of size (Fig. 5), and the photocell 16 is at least partially illuminated, and the element 15 is darkened completely. The signals at their outputs are 1 and O, respectively. These signals are fed to the input of logic device 22, and from its output the signal goes to the device 23 indicating the actual width of the workpiece, which indicates that. the workpiece has a normal width. Counter 26 Total counts down the unit, 2.Gooting is less than the allowed size. In this case, both photocells 15 and 16 are illuminated and the signals at their outputs are equal to 1. These signals, via logic device 22, arrive at the display device 23, on which information is displayed that the width of the workpiece is less than permissible. Counters 26 Total and 25 Less counts unit. 3.Providing more than the permissible size. In this case, both photocells 15 and 16 are darkened and the signals at the outputs are equal to O. These signals through the logic device 22 trigger the device 23, on which information is displayed that the width of the workpiece is larger than the allowable one. Counters 26 General and 24 More counting unit,. Information from counters 24-26 is fed to the input of the arithmetic unit 27, which performs the operation of calculating the reject percentage. This operation is performed on each measurement. The calculation results are presented on the display device 28. In the case when the number of defects exceeds a certain preset value (for example, the output of defects exceeds 10%), the buzzer 29 sounds a beep. The operator shuts down the machine to set up the automatic metering device. The application of the present invention will make it possible to obtain an economic effect by eliminating the receipt of defective blanks for further operations, eliminating manual control and simplifying the adjustment of the metering device.
