The device controls the processing of parts, their transportation and storage with simultaneous synchronization of the operation of gas transport lines, warehouse stackers and transport line. However, the device does not allow economical use of resources, taking into account the current state of electroplating, as a mode. The work of galvanic lines are pre-installed and do not change during the operation of the device. The state of the electroplating industry is assessed as unsatisfactory if the stocks of the machined parts are lower than the norm, because it is not guaranteed uninterrupted supply to the consumers with the processed details. In this case, it is necessary to process parts with insufficient reserves in the mode of maximum performance of electroplating lines, which allows you to replenish stocks more quickly. If the stocks of the machined parts have reached or exceeded the norm, then the state of electroplating is assessed as satisfactory, as the uninterrupted supply of the consumers with processed details is guaranteed. In this case, it is advisable to process the parts taking into account the criteria for minimizing resource costs. However, the known device does not change the machining modes of the parts depending on the state of electroplating. The purpose of the invention is to expand the functional capabilities of the system.

FIG. 1 is a block diagram of a galvanic production control system; in fig. 2 — memory block; in fig. 3, the first comparison block; on flash 4 - second comparison block; in fig. 5 - subtraction unit; FIG. 6 - priority block. The system (Fig. 1) contains information recorders 1 and 2, input device 3, blocks 4, 5 and 6 of memory, blocks 7, 8 to 9 comparisons, element 10 AND, element it OR, element 12 delay, generator 13 pulses pulse counter 14, subtracting unit 15 and 16, switches 17 and 18, register 19, de-gaiter 20, priority unit 21, stacker control blocks 22 and 23, galvanic line control blocks 21, 24 by the number of galvanic lines, control block 25 transport line.

Registrars 1 and 2 of information are intended for receiving, processing and issuing ip details. As registrars you can use, for example, a registrar, information type RI-7701. Priority unit 21 is designed to select a galvanic site, on which the parts must be worked, and on the operating mode of the vertical line. 974 Control units of a stacker-automaton of a rack-type automated warehouse of type STAC are used as blocks 23 and 22 of control of megabelers. The control galvanic lines of the ALG type are used as blocks 24 of the control galvanic lines. As a transport control unit 25, a control panel of a TP-200D-50 type push conveyor can be used. The system operates in two modes: in the input mode of the initial information and in the main mode of operation. In the input mode, the system works as follows. From the first recorder 1 of information, the codes of the parts that are in stock of the raw parts go to the input of the first memory block 4. All trunks of block 4, 5, and 6 of memory are organized in the following way: they contain m 27 memory cells (ft. The total number of types of parts passing through the electroplating shop), each of which is assigned to a specific part. When the codes of the detail codes arrive at the input of the first memory block 4, they are written through the first decoder 26 into the corresponding memory cells 27. Data from the input device 3 for each workpiece to the input of the second memory block 5 receives information containing the parts, the planned number of parts, the standard margin, which are located in the corresponding cells 27 of the memory. From the second recorder 2, information, containing data of the parts and the number of parts in the warehouse of processed parts, are received and located in the corresponding memory slots 27 of the memory to the input of the third memory block 6. The input of data from all three indicated sources ends with a special symbol. The end of the transfer, which is not recorded in the memory block, but is stored at the corresponding inputs of the first comparison block 7. By the coincidence of the three characters. The end of the transmission at the inputs of the first comparison unit 7 ends the operation of the system in the input information input mode. As a result, the transmitted data is located in the corresponding cells of memory blocks 4, 5, and 6; the remaining cells 27 do not contain memory. The system works in a casual manner. From the output of the first comparison unit 7, the first input of the element 10 I is given a single signal, indicating that the information has been entered in blocks 4, 5 and 6 of the memory. This signal triggers the pulse generator 13 and the counter 14 is triggered only if a single galvanic line is free (not loaded with details), which is provided by supplying information Q, the status of the galvanic line from the first outputs of the blocks 24.- 24 control galvanic lines through element 11 OR to the second input of element 10 I. If there is at least one free galvanic line, then the pulses from the generator output 13 and) pulses arrive at the input of the counter 14, the codes from the second output of which (from 1 to m) do entrances to decrypt 28 atoroa initiate read cycles data of the blocks 4, 5 and 6 of the memory. At the first output of counter 14, a pulse appears only when the second output has code m, which ensures the end of the recalculation cycle (all details are viewed) by supplying this pulse to the second input of the generator 13 pulses and disrupting its operation, and gating further operation of the system by supplying this pulse to the input of the switch 18 through the delay element 12. The occurrence of the next code from the second output of the counter 14 at the second inputs of blocks 4, 5 and 6 of memory leads to the reading of the next memory slots 27 of the memory corresponding to this code. The read data in parallel code is received, respectively, from the output of the first memory block 4 to the first input of the second comparison unit 8, from the output of the second memory block 5, the part cipher -.- to the second input of the second comparison unit 8, the planned number of parts to the first input of the first block 15 subtraction, the standard stock level is at the first input of the second subtraction unit 16, and from the output of the third memory block 6 to the second inputs of subtraction block 15 and 16. The first subtraction unit 15 is started when the codes corresponding to the planned number of parts (P) and the number of parts in the warehouse of processed parts (3) are received at its inputs and performs the following operation: g dj - deviation of the stock of processed parts from the planned level. Additionally, the subtraction unit 15 is determined from the deviation sign. At. About at the output of the block. A logical unit (positive positive) is formed, and at d), i is a logical zero (zero potential). Thus, the output of the subtraction unit 15 is given the deviation of the stock of the processed parts from the planned level and the sign of the deviation in the form of a parallel binary code. At the input of the comparison unit 8, a deviation sign code is received. When the code of the cipher of parts coincides in the comparison circuit 33, a logical unit appears at the output of this circuit, which is fed to the input of element 34 I. If element 34 of AND issues a signal to read the code of the cipher of parts from output register 35, if l O, then from output one register 35 information is not read. Thus, from the output of the comparison unit 8, the cipher codes of only those parts for which there is a reserve in the raw parts warehouse, the planned task, as well as the planned number of subscribers are not yet secured in the stock of the processed parts, go to the second input of the first switch 17. The second subtraction unit 16 is started when the codes corresponding to the standard stock of parts (Hi-) and the number of parts in the warehouse of processed parts (3 j) arrive at its inputs and performs the following operation:. where 1 1 st is the deviation of the stock of processed parts from the standard level. The calculated deviation of the stock of the processed parts from the standard level, together with the deviation sign, is received by a parallel-parallel code to the input of the first switch 17, to the other inputs of which signals are sent (free or nanted) of galvanic lines. The first switch 17 performs the following logical operation: if there is a part number at one input, and the state of the galvanic lines is such that parts of this number can be triggered on at least one galvanic line, then the output of the first switch 17 will generate codes and details, deviation stocks of finished parts from the planned level and the sign of deviation, which arrive at the registers 19, previously cleared by the trigger signal of the generator 13 pulses and recorded in it only when the current value deviates The number of stocks of processed parts from the normative level, which enters the input of the third comparison unit 9, is less than the previous one, coming from the output of the register 19 to the second input of the third comparison unit 9, which is indicated by

the signal from the output of the third comparison block 9, which arrives at the third input of the register 19. The cyclical operation of the system is realized by initial setting of the register 19 by a signal from the output of the element 10 and in the state corresponding to the maximum number in the discharge grid of the register 19. After processing the last cells of blocks h, 5 and 6 of memory from the output of register 19 to the input of the second switch 18 are received in parallel with the code) the details of the part and the deviation sign from the standard stock level of the processed parts corresponding to the part on which this deviates performance is minimal.

This information (part number and deviation sign) passes to the output of the second switch 18 only when a pulse from the output of delay element 12 arrives at the input of the second switch 18, indicating the end of the cycle of viewing the cells of blocks 4, 5 and 6 V of memory. The second input of the second switch 18 comes from the output of the transport line control unit 25, indicating the release of the transport line. Data from the output of the second switch 18 is fed to the input of the decoder 20. At the same time, iffr parts. issued to the first input of information registrar 1, which organizes through the first shtailer control unit 22 a cycle for delivering parts of the required cable to the transport line, and after the end of the cycle, corrects the information on the stock of the raw parts. The cipher of the part and the sign of deviation from the standard stock level, entering the input of the decipheror 20, initiates its work, consisting in determining the numbers of galvanic lines, the selected part can be processed by a jopbi. The position codes of the galvanic line numbers, followed by the deviation sign from the standard stock level, are received in parallel through the inputs of the priority block 21 to the registers 38, and through the other inputs to the elements 39 And signals are received (free or occupied) of the galvanic lines. After the information is recorded in registrar 38, the element 40 And gives a pulse to the counter 41, the code from which goes to the decipher 42. The pulses from the output of the decipher 42 are alternately transmitted through the elements 39 And to the registers 38 Thus, at the output of the block 21 priority code appears galvanic lmn1 | and with the lowest order number. This code through the element 43 OR zeroes the counter 41. The code of the galvanic line, together with the code of the mode mode indicator, goes to the corresponding block 24 of the control of the galvanic line. With a negative deviation from the normative margin (the normative margin is not created), the maximum performance of the galvanic line is set, which leads to the operation of the corresponding -24 J control unit according to the forced program, with a positive deviation (the normative margin is created), the mode leads to the work of the corresponding block 24; management under the program providing economy of material and energy resources. Simultaneously with the issuance of the mode code, the galvanic line control unit 24 sends to the corresponding i- and first input of the transport line control unit 25 a signal initiating a cycle of the transport line to deliver the raw parts of the corresponding warehouse to the selected electroplating line. The cycle of the transport line to send the processed parts to the appropriate warehouse is organized on the initiative signal from one of the J-24 galvanic line control units 24, arriving at the corresponding second input of the transport line control unit 25, if there is a signal from the output of the second stacker control unit 2, signaling the acceptance of the treated parts. Receiving finished parts at the initial position of the stacker of the warehouse of processed parts starts the cycle of operation of the second shtailer control unit 23, which ends with placing the processed parts in the warehouse cell specified from the second information recorder 2 At the end of the work cycle, the second shtailer control unit 23 sends a signal to the second recorder 2 The end of the cycle, which leads to the correction of information on the state of the warehouse of machined parts, as well as the contents of the third memory block 6.,

Further operation of the system is carried out cyclically (after the release of the transport line), and the next cycle (ending with the loading of the next electroplating line) can be initiated by receiving (sending) parts in stock and processed parts, receiving (sending) parts in the stock of processed parts, entering (correcting) information about the plan and standard stocks from the device 3 input.

A necessary condition for the performance of the next cycle of the system operation is the presence of signals about the release of the transport line and at least one galvanic line. Thus, the expansion of the functional capabilities of the system in comparison with the prototype is ensured by the fact that when the required inventory level of the machined parts is reached, the system converts the galvanic lines into the operation mode with reduced costs of material and energy resources, which increases the efficiency of electroplating production. Moreover, the electroplating lines are operatively transferred to operating mode 7 with increased productivity. This allows for the timely replenishment of stocks of machined parts, thereby improving the supply of consumers of electroplating products. Predpagayem system is most effective in electroplating, controlled by a computer. In this case, computer controlled computer. In this case, the control units of the pilers, the control units of the transport line will be used as local subsystems, subordinate to the computer and operating according to the program specified from the computer.
