    The invention relates to a device for reading tags and can be used in the printing industry.
    The purpose of the invention is to increase the efficiency of reading tags.
    The goal is achieved by the fact that the device for reading tags is preliminarily in a printing machine, containing its playback unit of a printing medium with a label optically connected to the photodetector unit, the control unit, including a trigger, memory element The I element, the counter and the information output control unit connected to the control unit have a mechanical switch unit, a manual data entry unit, an additional counter, a comparison unit, while the outputs of the photo-receiving unit through the mechanical switch unit connected to the trigger input and the first input of the element I, the second input of which is connected to the trigger output through the memory element, the output of the element I is connected to the input of the counter, the first output of which is connected to the first input of the comparator connected to the second input through an additional counter with the output of the block manual data entry, the second output of the counter being connected to the first input of the control information output node connected by the second input to the output of the comparison unit.
    FIG. Figure 1 shows a block diagram of the output of the counter 17 connected to the first input of the control information output unit 6 connected to the output of the comparator unit 23 via a second input.
    The tag reader operates as follows.
    The photodetector system consists of the line-by-line arrangement of the photodetectors at a minimum distance from each other and, together with the control circuit 10, the photodetectors are manufactured in series production. The size of the individual photodetectors 9 and the distance between them provide good matching with the required optical resolution and advantageous digital signal processing. In this case, it is possible to read both from the resting and moving sheets 1 or the tape. Presented in FIG. 1, the tag reader determines the distance between the two 20 marks of mark 2. This measurement is a relative measurement with respect to register marks. The drive marks 2 on the sheet 1 of the original 27 are illuminated by the light source 7 of the optical system 4 in transmitted or incident light using the lens 8 of the optical system 4 being projected onto the photo-receiver 9 of the circuit of the photo-receiving unit 3. The optical zoom of the lens 8 can be selected accordingly.

    or several individual photodetectors 9.
    The individual photoreceivers 9 are read by the photodetector control circuit 10, which is controlled by the clock sensor 11. The control circuit 10 supplies a signal to the individual photodetectors 9. Depending on the operating principle of the photodetector 9, the output of the control circuit 10 is proportional to the potential or voltage. The respective outputs of the photodetector control circuit 10 are designated as potential output Q and voltage output.

    In this case, the outputs of the photodetection unit 3 through the block 26 of the mechanical switch 11 of the photoreception unit 3 to the control unit 5 are triggered by a block 26, which is shown in the on position of the potential output Q. The control unit 5 determines the distance of the darkened volts connected to the trigger input 14 and Each of the two individual photodetectors is the input of the AND 15 element, the second input of which is connected through the memory element 16 to the trigger output 14. The output of the AND element 15 is connected to the input of the counter 17, the first output of which is connected to the first input of the Approximately 23 comparisons connected by the second input through an additional counter 22 with the output of the manual data entry unit 21.

    Consider the principle of operation of the control unit 5 for the potential output Q of the photodetector unit 3.
    55 The distance between the register marks on sheet 1 of the original 27 is determined by counting the illuminated individual photodetectors 9. From the output circuit of the node 3 photodetectors
    the second output of the counter 17 is connected to the first input of the control information output unit 6 connected by a second input to the output of the comparison unit 23.
    The tag reader operates as follows.
    The photodetector system consists of the line-by-line arrangement of the photodetectors at a minimum distance from each other and, together with the control circuit 10, the photodetectors are manufactured in series production. The size of the individual photodetectors 9 and the distance between them provide good matching with the required optical resolution and advantageous digital signal processing. In this case, it is possible to read both from the resting and moving sheets 1 or the tape. Presented in FIG. 1, a tag reader determines the distance between two application marks 2. This measurement is a relative measurement with respect to register marks. The drive marks 2 on the sheet 1 of the original 27 are illuminated by the light source 7 of the optical system 4 in transmitted or incident light using the lens 8 of the optical system 4 being projected onto the photo-receiver 9 of the circuit of the photo-receiving unit 3. The optical zoom of the lens 8 can be selected accordingly.

    The node 11 of the photodetection unit 3 to the control unit 5 occurs via block 26, which is shown in the switched on position of the potential output Q. The control unit 5 determines the distance darkened by register marks of 2 individual photodetectors 9.
    Consider the principle of operation of the control unit 5 for the potential output Q of the photodetector unit 3.
    55 The distance between the register marks on sheet 1 of the original 27 is determined by counting the illuminated individual photodetectors 9. The amplitude-modulated signal is recorded from the output circuit of the photodetector unit 3. The pulse amplitude depends on the illumination of the individual photodetectors 9 (Fig. 1). When the threshold value is exceeded, trigger 14 generates a signal UT. This signal, representing the first watermark 2, sets the memory — memory element 16 so that AND 15 opens. The output pulses of the photoreceiver node 3 now enter the counter 17. The second trigger signal 14, representing the second register tag 2, blocks the AND 15 element. The state of the counter 17 in this case represents the distance between the register marks 2.
    When using the output voltage and photodetector unit 3, the distance between register marks 2 on sheet 1 of original 27 is determined by counting the pulses generated by clock sensor 11 through a conductor between both dark signals for register marks 2. Amplitude amplitude modulated signal. The amplitude depends on the lighting of the individual photodetectors 9 (Fig. 1).
    When the threshold value is exceeded, trigger 14 generates a signal UT. This signal, representing the first register tag 2, establishes element 16 so that element 15 opens. The output pulses of the clock sensor P, which, using the photodetector control circuit 10, polls individual photodetectors 9, enters the counter 17. The second trigger signal 14, corresponding to the second register mark 2, closes AND 15. The counter 17 state represents the distance between both register marks 2. Registry marks are printed using multi-color printing masks in various colors. Since different printed material is used, various light conditions are implemented for the photodetectors 9. For the correction, it is necessary to use trigger 14 in the control unit 5 with an adjustable threshold value to co-ordinate with the circumstances. The state of the counter 17 of node 5,
    five
    containing the measurement results, is supplied to the control information output unit 6 with indicator 18, which indicates the state of the counter using such known devices as a digital indicator
    or a display, to the recorder 19, which outputs the measurement results on the printing apparatus, and to the data processing interface 20. The latter serves for further statistical processing of the obtained measurement results, for example, the formation of an average value or the determination of the distribution function.
    In many cases, it is sufficient to signal an excess of the limit value. For this purpose, a node 25 is used to determine the excess of the limit value, which is connected to the counter 17 of the control unit 5.
    The state of the counter 17 is compared with the state of the pre-set counter 22, which is set by the manual data entry unit 21 according to a predetermined limit value.
    A comparison of the states of the counter 17 and the presettable counter 22 occurs in the comparison unit 23. In this case, we are talking about an element that, when comparing two digital states of the counters, generates signals "Exceeding the limit value and" Lowering the limit value. These signals from block 23 are fed to a dispensing unit 6 and are signaled there on indicator 24 of indications of an excess of the limit value.
    FIG. Figure 2 shows the original 27 with an absolute dimension with respect to register mark 2. Here, the distance between the sheet edge 13 and the register mark 2 is measured. In this case, sheet 1 is superimposed on the drawing plane 12, which has a reflection coefficient different from sheet 1.
    Use of the invention improves tag reading efficiency.
    The invention was recognized on the basis of the results of the examination carried out by the Office for the Invention of the German Democratic Republic.
