(54) DEVICE FOR PROGRAM CONTROL OF AUTO-OPERATORS OF GALVANIC LINE

The invention relates to regulatory and control systems, in particular to software control systems, and can be used to control auto-operators of electroplating or paint-and-lacquer lines.

A device for software control of galvanic line athoperators is known, comprising a bath load address switch, a time block, horizontal and vertical movements of an auto-operator, a comparison unit, an auto-operation movement sensors unit. The inputs of the horizontal and vertical movement control units of the auto operators are connected to the time block outputs, and the outputs are connected to the inputs of the auto operator actuator blocks l.

The operation of the device begins with the development of the vertical movement of the auto-operator on a signal from a block of time. Then, the signal from the control unit for the vertical movement of the auto-operator records the address in the address register. This address is compared in the comparison block with the current position of the auto operator determined by the sensors fixing its position. As a result, the comparison unit generates one or another signal to the horizontal displacement control unit to move the auto-operator back and forth. The auto operator will move to the specified position at which the actions required by the program will be performed. When running

10, by an auto-operator, the device ensures the rhythm of the issuance of high-quality products and allows control of the line operation over time.

The disadvantages of the known devices are low line capacity due to significant autorepair downtime of auto operators in the cycle, due to the independence of their work and the expectation of one auto operator to complete the functioning of another auto operator in their area of work, as well as inefficient use of control equipment in connection with two identical control devices for two auto operators and the resulting low occupancy ratios of individual units twa.

Before starting, the logic unit 1 is configured to control two auto-operators.

 the galvanic line work on the cyclogram is preceded by the initial setting of the auto-operators, which is automatically performed after the device is put into operation. Then, the joint execution of the program of joint operation of two auto operators took place.

In the first bar, the first auto operator moves horizontally to the position specified by the cyclogram and the second auto operator console moves up or down vertically, the second auto operator moves horizontally in the second cycle, and the first auto operator console moves vertically. Then the third cycle is performed and thus the entire program is executed cyclically. The cycle time is variable. In addition, the device provides for the completion of an extended cycle, in which for some critical operations the suspension of the ropes into the bath is lowered, the parts are kept in the bath for a short time and the console is raised upward during the time of one cycle. The device allows to perform cycles with no horizontal or vertical movements for one of the auto operators, depending on the work of block 6, time for the purpose of performing in (holding the bath time in the bath and obtaining a quality coating.

The execution of the program cycle begins with the logical block 1 issuing the address specified to the first operator, and writing the code of this address to the register 2. Unit 1 also issues a series of clock pulses, one of which is intended for briefly connecting the 8 sensor unit of the second auto operator to the comparison unit 3 with analysis of the situation to avoid the collision of two auto operators. The remaining pulses of the series serve to connect the block 4. To block 9, as well as block 5 to block 10, and then connect the sensor 7 to block 3 of the comparison. The control unit 1 interrogates the sensor 7, the position of the block, and the code of the current position of the auto-operator enters the comparison unit 3. In addition, the address register 2 transmits to the comparison unit 3 a code for the specified position of the auto operator.

Depending on the sign of the result of the comparison, the codes in the comparison block 3 trigger either a trigger more at the sign (+) or a trigger less at the sign of -), or the trigger is equal to

0 when the result of the comparison is zero. These signals determine the direction of movement of the first auto operator and are fed to block 4, which outputs a turn on signal of block 9. At the same time, block 1 sends signals to block 5 to turn on block 10 and to time block 6 to monitor the movement of auto operators in time.

Before lowering the suspension with details into the bath, the unit 5 directs the interrogation signal B to the sensor 8 to determine the occupancy of the bath and stops the control device in the event of an emergency determined by the occupancy of the bath. The autoconsole console can take up two vertical positions position - upper or lower, fixed by the limit switches of the sensor 8, then the shutdown of the vertical movement of the second auto operator is performed directly by the block 5 when the limit switch is triggered sensor 8 without the fate of unit 3 comparison.

five

When the first auto operator moves horizontally, unit 1 interrogates sensor 7, which delivers the current address code to comparison unit 3, where this code is compared with the given code. The movement on the horizon of the first auto operator is carried out until the indicated codes coincide. In case of their coincidence, the comparison unit 3 issues a signal to the 4 unit for stopping the first auto operator.

5 When horizontally moving the first auto operator, unit 3 compares the magnitude of the difference (&) of the given and current address codes, and this difference compares with one.

Claims (2)

O With / & {1 auto-movement horizontally occurs at a faster speed, with / & | 1 The movement of the auto-operator occurs at a low speed to increase the accuracy of positioning of the cycling. Turning off the first auto operator when it moves horizontally and the second auto operator when it moves vertically ends the first cycle of operation of the control device. The second cycle begins. It is similar to the first, with the only difference being that the vertical movement control is performed for the first auto operator, and the latter is controlled by the second auto operator 5. Similarly, all other tact operations are performed. Thus, the described device, when controlling a two-line operator, improves the line performance by 5-7% by reducing the unproductive times of just auto-operators, caused by the lack of tact synchronization of their work due to the simultaneous (parallel) operation of the control units of horizontal and vertical movements due to device, having a coherently synchronized algorithm for the functioning of two interacting auto operators, and also to effectively use ravl yuschee equip ment in connection with reducing the number of blocks to reduce the cost of the control equipment.
