    one, ,
    The invention relates to the printing industry, in particular to devices for controlling the flow of paint.
    A device for controlling installation and drive units of a printing press is known, having adjustment screws of an inking apparatus, in which a stepping motor is used to enable the stepwise movement of the ductor roller. In addition to the adjusting screws of the inking apparatus, this device also contains parallel mounting screws of the inking knife, mechanisms for dosing paint with parallel setting screws, and mounting links for moving the dowel roller}.
    The aim of the invention is to improve the dosing accuracy of the ink.
    This is achieved by the fact that the device has a control unit and n limit switches, with the input of the control unit connected to the switching unit; and its output is with stepper motors. Each of the limit switches is electrically connected with. control signal generation unit.
    FIG. 1 shows a paint metering mechanism, side view; in fig. 2 - scheme
    passing signals through a remote control of an ink dispenser; in fig. 3 is a circuit diagram of a control unit.
    The ink dispensing device 1 has a colorful knife 2, the position of which, relative to the ductor 3, determines the gap of the colorful knife and the amount of paint supplied.
    In order to change the position of the inking knife 2 with respect to the ductor roller 10, the inks of the inking knife 2 are rotatably mounted in the device for dispensing ink 1, the levers 4 of the inking profile, which have an abutment plane 5 for the individual adjustment screws 6 of the inking apparatus, as well as abutment planes 7 for the apparatus 15- Bent vertically relative to these planes of parallel storage strips 8, they are mixed in the paint metering device. The movement of the parallel accumulator strips 8 is guided by the colorful knife with parallel screws 9.
    The paint metering device 1 is rotatably mounted on the eccentric bushing 10. To rotate the paint metering device, there are parallel mounting screws 11 installed in it, which rest on the fixed yoke 12.
    The adjusting screws 6 of the inking unit, the parallel set screws 9 of the colorful knives and the parallel set screws 11 of the metering unit have multi-couplings 13, which are connected by drive units 14 and 15 with the stepping motor 16.
    The screws 6, 9, and 11 have front and rear starting positions, with the front starting position having the closest position to the ductor, and the back starting position being the most distant from it.
    For the individual reference positions, the following designations are used;

    Installation regulation
    In this case, screws 6 are referred to as A3, and parallel set screws of the colorful knives 9 are designated A5.
    To establish an uneven ink profile, the following setup program must be followed so that the mutual influence of individual installation processes can be eliminated. -A3
    To establish a uniform inking profile, the following setup program must be executed.
    To accumulate an uneven ink profile, which is set using the parallel setting screws of the ink knife 9, to temporarily stop the current run, to control cylinder adjustment with a flat impression, after which it continues to issue a run with the ink profile installed, or to temporarily stop the current run for for flat printing, the following setup program must be executed:. ,
    The length of the inking profile is set using a stepper motor. To perform the installation of the length of the ink profile by means of a stepper motor of an ink dispensing device located at the ductor.
    The following installation program must be followed:
    These pre-fixing conditions can be applied to other designs of the paint dosing device. ,
    The signal flow diagram for the remote control of the paint metering device (see Fig. 2) includes elements A, B, C, D forming the control unit, elements 1.7-20 forming the switching unit, elements 21-24 of the stepping motors control; stepper motors 25-28; screws 29, 6, 9, and; elements 30-35 of the manual control unit; limit switches 36-42.
    The control unit element A has four inputs and four outputs 1 A, 2 A, 3 A, 8 A. Element B also has four inputs and four outputs 1 B, 4 B, 5 B, 7 B. Element
    8 has three entrances and three exits 5 V, 6 V, 7 V. Element D has two entrances and two exits 9 D and 10 G.
    The control elements of the jog motors 21-24 each have two inputs for obtaining two initial states.
    The control unit element circuit A (see Fig. 3) has three logic elements AND 43, 44, 45. Element A is controlled from limit switches 36, 37, 41 and from element 17 of the switching unit.
    The schemes of elements B, C, D are similar in principle to the action of element A.
    When the necessary program is executed, the control signal through one of the elements 17-20 is fed to the input of the corresponding element A, B, C, and G of the control unit.
    At the output signal 1A of element A, it is fed through element 21 to the stepper motor 25. The stepper motor drives the screw 11 to the required position. At the same time through a closed limit switch 41 on.the second input of the element A receives a signal. Passing through element 43, the signal through element 22 acts on the pinch motor 26 and screw 9. At the same time, the signal from the 8 A output acts as an element of manual control 33. Moving the screw
    9calls the operation of the limit switch 37 and thereby the signal at the output 2 A. This signal acts on the element 34 and through the element 23 and the jog motor 27 on the screw 6. After setting the screw 6 to the desired position the signal through the limit switch 36, the element 45 enters to output 3 A and to the manual control element 30, freeing it to control.
    The same principle works for other programs as well.
