The invention relates to equipment for electroplating and can be used to control the transport mechanism of both a conventional electroplating line and the line included in the HAP electroplating system.

The purpose of the invention is to improve the accuracy of positioning,

The drawing shows a functional diagram of the control unit of the auto-operators of electroplating lines.

The control unit consists of a control panel 1 control unit 2 programs, block 3 sensors top and

the lower positions of the auto operator, are blocked by the J5 operator numbered. Before the start

ka 4 time-shifts, control unit 5, rake teeth counting unit 6, 7 position decoder, decoder speed command 8, decoder 9 engine shut-off and braking device decoder 9.

The outputs of the control panel 1 are connected to the program block 2, the rack counting teeth block 6, the first inputs of the decoder 7 positions, the decoder 8 of the speed change command to the decoder 9 of the engine shutdown command and the activation of the braking device. The second inputs of the said decoders are connected to the output of the rack counting teeth block 6. The inputs of the control block 5 are connected to the first output of the program block 2 directly to the second output of the program block 2 via the time delay block 4, and the output of the speed command decoder 8 the decoder 9 of the command to turn off the engine and turn on the braking device. The inputs of the program block 2 are connected to the block 3 of the sensors of the upper and lower positions of the auto operator, the decoder of 7 positions and the console 1 of the control.

The control panel 1 contains a set of keys with which the teeth number codes are entered into the decoders, as well as the number selection buttons

work in the (ROM) of the decoder 7 positions; the operator from the control panel enters codes for the numbers of the teeth, in front of which the auto operator should stop

20, in the ROM of the decoder 8, the speed switch-over command records the codes of the teeth numbers, opposite which the auto operator must change the speed, in the ROM of the decoder 9 of the shutdown command

25, the engine and the braking device starts recording the codes of the numbers of the teeth, upon reaching which it is necessary to turn off the speed and turn on the braking device. Auto operator

j is required a processing program. The motor control commands of auto operators are sequentially selected from block 2 of the programs and entered into block 5 of the control. Each sample of the next follow-up control command is carried out using signals from the block of 3 sensors of the upper and lower positions of the auto-operator or from the decoder of 7 positions.

no galvanic line. Block 2 of the programs is a collection of addressable memory cells. The block of 3 sensors of the upper and lower positions of the auto operator is located on the transport mechanism. The time slice block 4 is a code controlled time counter. The control unit 5 converts the commands and controls the number of the tooth that the auto operator passes. The code of the tooth number is fed to the decoder, which matches it with the code stored in the memory and, if the codes coincide, form the corresponding signal.

laziness in the control signals of the engines of auto operators. The tooth counting unit 6 of the slats is made in the form of a tooth passage sensor located on an auto-operator and a reversible counter.

Decoders 7-9 are comprised of read-only ROM storage devices and coincidence circuits. The data in the ROM is recorded before starting operation from the control panel.

The device works as follows.

All the teeth of the auto-guide rail are numbered. Before the start

work in the (ROM) of the decoder 7 positions; the operator from the control panel enters the codes of the numbers of the teeth, opposite which the auto operator should stop,

30 is set to the starting position. When you press the Start button on the control panel, the tooth number code of the initial position is entered into the block 6 for the teeth counting of the slats, and in the program block 2, the processing program is selected. The motor control commands of the auto operators are sequentially selected from block 2 of the programs and entered into block 5 of the control. Each sample of the next control command is carried out by signals from the block of 3 sensors of the upper and lower positions of the auto operator or from the decoder of 7 positions. Time intervals are formed with the help of a block of 4 time snapshots. When moving the suspensions with parts forward along the line in the working stroke mode, as well as moving the auto-operator backward without details in the mode

determines the number of the tooth that the auto operator passes. The tooth number code goes to a decoder, which compares it with the code stored in the memory and, if the codes match, generates a corresponding signal.

Let the auto-operator perform the work stroke. When a descram is triggered313

Torus 8 of the speed change command to the input of the control unit 5 receives a signal on which the auto-operator reduces the speed. When the decoder 9 is triggered, another signal is sent to the input of the control unit 5, which switches off the engine. At the same time, the brake device is activated by this signal. After some stopping distance, the auto-operator stops at a predetermined position. In this case, the decoder 7 position is triggered, according to the signal from which the next command is sampled.

The use of the unit for counting the teeth of the lath, position decoder, decoder for the speed change command and the decoder for the engine shutdown and braking command, the device distinguishes the proposed device from the known one. Counting the teeth of the auto-guide rail allows you to generate additional control commands without introducing additional sensors and changing the process program.

The use of an additional command for switching speeds and a fixed advance on issuing a braking command improves the accuracy of positioning, which reduces the likelihood of failures in the operation of the galvanic line.
