FIG. 1 shows a block diagram of a device for software control of auto-operators of multi-process automatic electroplating lines; in fig. 2 shows circuit design variants of an auto-operator speed control unit. The block diagram (Fig. 1) shows galvanic lines 1, containing a number of baths 2, auto operators 3 s, located on them the reed sensors of positions 4 and the positions of the grippers 5, electric drives horizontally 6 and vertical 7 movements associated with the device 8 of the auto operator. which includes block 9 of control, indication and choice of operating mode, block 10 of clock distributors with a generator 10, block 11 of information recording control 11, block 12 of read control, block 13 of registers, command memory 14, a time keeping device 15 time, a block of 16 comparisons, a reversible binary counter 17 positions, a block of 18 electronic clocks, a block 19 of generating control commands, matching, synchronization and slingshielding, a block of 20 speeds of horizontal movement of an auto operator, a block 21 of speed of vertical movement of a suspension, block 22 electronic switch 22 systems, input device 23, control and self-tracing, DS 24 decoder, OR 25 logic element, AND 26 logic element, AND 27 OR logic element, trigger 28, PB 29 time relay, optical yes tach OD 30. The device for software control of auto-operators of multiprocess automatic lines of G-mshanopovery works as follows. Before starting, the auto-operator checks the operability of the main functional units of the circuit, memory devices 14 and 15, valves and generator 10 clock pulses, blocks 11 and 12 of the recording and reading control using test programs and control and self-checking schemes. At the end of the test, the operator selectively or sequentially enters the memory 14 and 15 of the program control unit 8 connected via the switch 22 to the input device 23 with the appropriate technological program, after which the input device and the switch 22 are turned off, and the control unit 8 is put into autonomous operation mode i.e. works with the operator 3. For this, the operator on the control and display unit 9, selects the operating mode sets the switch to the Automatic operation position and starts the system. The Start signal is triggered by a pulse generator that powers the distributors of block 10. The block 10 clock distributors and read control skins of block 12, which is connected to the operational memory 14 and 15 of the commands and timeouts, are read Hitsys in the memory cells of information. Each memory device has its own output memory registers, which are found in one block of registers. The number of the bath, which is recorded in the output register of the memory device 14 of the commands, enters the comparison block 1, where it is compared with the current value of the reversible binary counter 17. The comparison result goes S the control unit 19 that controls the movement of the auto operator Forward, Stop, Back . Based on the attribute that is part of the command code, is generated. signal for vertical movement If there is a time delay during a command, the time counter 18 is started, the output values of which are compared with those stored in the output registers 13 of the memory and when they match in the comparison block 16, a signal is generated for the end of the delay and permission to execute the next command. The motion control signals generated in the command generation units 19 are fed to the inputs of the horizontal and vertical movement speed units. These signals are allowing for the selection of the optimal speed drive. The selection of the speed of movement of an auto operator can be made either automatically or along a programmer. FIG. Figure 2 shows a variant of a horizontal autotransference speed block circuit in an automatic mode that meets the following conditions: horizontal displacement asynchronous 4-speed electric motors. Change of rotational speed of electric motors occurs due to switching of stator windings, logic of changing skrrosti: movement with load at 3 d n -1 speed - TL movement 2 4 D n W -1 without load D 1 L where D is the difference module between the program the bath number and the current position of the auto operator, n - the given positions of the auto operator, i - the current value of the positions of the auto operator; n-1 is the maximum distance between the positions, I - @ are the commands for switching on the corresponding speed. The module of the difference between the set and current values of the auto-operator comes from the block 16 comparing its output register in block 13 of the register to the decoder DS 24 of the block 20 speed, where it is converted from binary code to decimal. The logic elements And 26 decide the choice of speed when the inputs of one of the circuits simultaneously signal the horizontal displacement from the signal block 19 from the position sensors and the difference modulus. The command formed by block 20 of speed horizontal movement (1-5) enters block 19

to power amplifiers, after which it is fed to a switching circuit of the stator windings of an electric motor for horizontal movement (Fig. 1).

FIG. Figure 3 shows the variation of the speed according to the program. The mystery is received from the register 14. The command from the command register 13 is fed to the decoder of the DC 24 of the horizontal displacement rate 24 unit. The schemes AND block 20 of the horizontal movement speed issue a command to turn on the speed corresponding to the program.

FIG. Figure 4 shows an example of the solution to varying the speed with vertical movement of the auto-operator grips. Signals with a load, without a load, come from the sensor unit and provide the corresponding state of the trigger 28 of the block 21 of the speed of the vertical movement of the suspension.

The direct output of trigger 28 corresponds to the signal With load, and the inverse - with load.

From block 13, registrars are allowed

vertical displacement, which is part of a command read from memory 14 to the inputs of logic gates And 26. In addition, a signal from the outputs of the trigger 28 is supplied to these elements.

 If the operator is loaded, then the grips are lowered with the suspension

The time relay PB 29 is turned on, which provides an intermittent operation of the electric motors.

Forming a signal without load, the grippers are lifted at a constant speed.

It is also possible to change the speed when lowering in the automatic mode (Fig. 5).

In this case, an optical sensor can be used (OD; 30 parts entering the fluid, the signal from which is fed to the direct and inverse inputs of the AND 26 circuits. If trigger 28 is in the Load condition, a command is generated to turn on speed 1, if Without cargo - speed O.

Thus, the introduction into the proposed device of programmed control by an auto-operator of a speed block of horizontal movement makes it possible to use the work of auto-operators at high speeds at idle (without load) or further movements with cargo.

By increasing the speed of the auto operator twice as compared to the existing one in practice, one operator can serve a much larger number of baths, or use instead of two auto operators on the line, one. The reduction in time for the operator's mileage between baths is reflected in the quality of the coating, since the degree of oxidation of the surfaces decreases during the transition from one bath to another. Specific

0 indicators depend on the control program entered into the control system.

The introduction of the block of speed of movement of the grippers will allow for more reliable operation of the auto-operator when working with large-sized or light parts, since it eliminates dropping or tilting the suspension with the details of Q or touching the parts between themselves when lowering them into the liquid.

The economic effect from the use of the proposed device is 5.9 thousand rubles.
