The setting device may be an interface module.

The output of the setting device 6 is connected to the information input of the memory block 7 and to the input of the element OR 18 of the recording control block 8. The output of the element OR 18 is connected with the input of the counter 19 products, the capacity of which should not exceed the number of cells of block 7 and be no less than the maximum possible number of sortable products that can simultaneously be on the conveyor.

a vibrator 21, the outputs of which are connected to the inputs of the element 22, the output of which, in turn, is the output of block 8 and is connected to the V input (write enable) of block 7.

The synchronization unit 9 contains a clock generator 23 and a counter 24, the bits of which are divided into 3 groups, each of which forms a separate output of the block. The capacity of the junior group bits is equal to the capacity of the counter 19. Their outputs form the first output of block 9, which is connected to the address input of block 7, to one of the inputs of the code comparison circuit 13 and to one of the inputs of the comparison circuit 20, of the write control block 8. The second output of the block is formed by the outputs of the group of subsequent bits (at least two) and is connected to the input of the decoder 25 (the synchronization input of the block 10 of the account and storage). The outputs of the subsequent high bits of the counter 24 form the third output of block 9. The capacity of this group of bits must be at least the maximum possible number of drives (sorting characteristics). This output is connected to the address input of the memory element 26 of the counting and storage unit 10, to one of the inputs of the code comparison circuit 14, to the control input of the multichannel imaging unit 11, and to the information input of the decoder 12.

The block 10 also contains a counter 27 and an element AND 28. The output of the counter 27 is the information output of the block 10 and is associated with the information input of the memory element 26. The clock deflector 25 controls the operation of block 10. Its first output is connected to the V input of counter 27, the second output to one of the inputs of element 28, the second input of which forms the information input of block 10 and connected together with one of the inputs of element 15 to the output of block 11. The output element And 28 is connected to the C input (clock) of the counter 27.

The third output of the decoder 25 is connected to the V-input (recording control) of the memory element 26 and forms the synchronization output of the unit 10, also connected to one of the inputs of the element 15. The fourth output of the decoder 25 is connected to the input (set zero) of the counter 27. Information input the counter 27 is connected to the output of the element 26. An enabling signal is constantly supplied to the read control input of the element 26.

The device also contains a drive control unit 29 (the functional block diagram of the unit and its external connections are not shown). This unit can be performed by any known scheme and has all the necessary elements (starters, simistors, etc.) to control switching on, stopping, reversing, or switching to other speeds of the drive (electric motor) 2.

Virtually any known actuator can be used. At the beginning of the conveyor, in front of the first accumulator, a sensor 30 for the presence of a product is mounted, connected to a magnetic tag recording unit made in the form of a one-shot, generating an output signal of the required duration along the leading or falling edge of the signal outputted by sensor 30.

The output pulse from the one-shot 31 is fed to the input of the recording magnetic head 32. To get a signal to the input of the multichannel shaper 11, the duration of which would be close to the length of the signals from the magnetic sensors 4 present the product, a single-shot 33 is provided in the circuit. head 34, erasing magnetic tags from the conveyor body.

The multichannel driver 11 of the input signals from the sensors 4 may have a functional circuit shown in FIG. 2. It contains the switch 35, the decoder 36 and the circuit, each of which has an element And 37, one-shot 38 and 39, element And 40. Each element And 37 one of the inputs connected to one of the outputs of the decryptor 36, the other input to the corresponding sensor 4, and the third to the inverting output of the one-shot 39. The direct outputs of the one-shot 38 are connected to the inputs of the switch 35. The information input of the decoder 36 and the control input of the switch 35 form the first control input of the driver 11, which is connected to the third output of the synchronization unit 9. The second control input is formed by the inputs of the elements 40 and is connected to the output of the decider 25. If the operator controls the sorting from the console 16, the device may contain a block 41, one of the possible embodiments of which is shown in FIG. 3. Node 41 will keep circuit 42 comparing codes, element OR — NO 43, element AND 44, elements OR 45 and 46, and D-flip-flop 47. The output of block 41 is connected to drive control unit 29. The device may also comprise an output driver 48 for obtaining the duration of the output signals, which is necessary for actuating the actuators 5.

The device works as follows.

Before being received on the conveyor 1 of the first product or when the power is turned on, the counters 19 and 27 and blocks 7 and 26 are reset. The code at the output of the sensor 6 is equal to 0. If the number of signs of sorting is taken to be (M), then the number of bits of the encoder 17 is equal to K; if the capacities of the counters 19 and 27 are equal, then the number of their bits is L, respectively.

When the first product is fed to the receiving part of the conveyor 1, at the output of setpoint 6, the K-bit code of the accumulator number appears in which it is necessary to unload this product. The code simultaneously enters the D-input of block 7 and the element OR 18, the output of which appears is one (since the number of any accumulator is different from zero and there is at least one unit in the code), which is written to counter 19 and from its output in the L-pass code, it is fed to the input of the comparison circuit 20, at another input of which the code coming from the first L-bit output of the synchronization unit 9 is continuously changing. When the codes match, i.e., at the moment when the first output of block 9 is a code equal to 1 (0 ... 01 in binary code), a single signal appears at the output of the code comparison circuit 20, which is fed to the first input element and 22.

At the output of the element OR 18, the single signal will be for a time when the drive address code is at the output of the setpoint device. To normalize the time of a given signal, i.e., so that during the time of a given signal it could go through a full counting cycle from O to N (i.e. a cycle consisting of N cycles, or N-cycle) at the first output of the block 9 synchronization provides one-shot 21.

When the codes coincide at the inputs of the comparison circuit 20 and if there is a reference signal at the output of the setter 6, the unit 22 appears at the output of the element 22, which is fed to the V input of block 7. At this moment, the accumulator address code goes to the D input of block 7 , and the A-input (address) - the code from the first output of block 9, corresponding to the job number (product number) in order. For the first product, it is 0 ... 01, i.e. the address code of the accumulator in which the first product needs to be unloaded is recorded in the first cell of block 7. It is necessary that the time of the signal produced by the one-shot 21 does not exceed the time for issuing the code addresses of the accumulator are set by the sensor 6, since otherwise, after the end of the signal at the output of the setting device, the zero code can be rewritten into the cell of the block 7.

When the first product acts on the sensor 30, a signal appears at the output of the latter, on the leading or trailing edge of which, the recording unit 31 produces a current pulse of the required duration and amplitude, which is fed to the recording magnetic head 32. The magnetic field arising in its working gap magnetizes the section of the conveyor chain, i.e., creates on it a magnetic mark located at a certain distance with respect to the front or rear end of the product.

Similarly, magnetic tags are applied to the conveyor drag chain and when all subsequent products arrive at the receiving part of the conveyor.

When the first product enters the first accumulator, the magnetic sensor 4 installed in it reacts to the magnetic field of the tag under the end of the product and generates an electrical signal that goes to the first input of the driver 11.

During the operation of the circuit, the numeric codes on all three outputs of the synchronization unit 9 vary from zero (0 ... 00) to a single (I ... 11). Moreover, the code on the first output of the synchronization unit 9 has N states, i.e. the complete cycle of accessing this code from the state (0 ... 0) to the state (1 ... 11) consists of N-cycles. The code at the second output of block 9 has at least 4 states (consists of 4 cycles), and the code at the third output of the block 9-M states (M-cycles).

The complete cycle of code access at the first output of block 9 is an N-loop, and the components of its cycles are N-cycles; the code cycle at the second output of block 9 is the cycle of block 10, and the code cycle at the third output of block 9 is an M-cycle consisting of M-ticks, each of which constitutes an N-code turning cycle and contains N ticks .

For the received quantities of drives (3) and products that can simultaneously be placed on the conveyor 7, the first output of the synchronization unit 9 is made three-digit (), the code on it varies from O to 7 (from 000 to 111 in three-bit binary code) with the frequency fp of the generator 23. The second output of the block 9 in the example shown is simplified for two bits, the code on it varies from 0 to 3 (from 00 to 11 in binary code) with the frequency fr / L. The third output of block 9 is performed in this case by two-bit (), the code on it varies from 0 to 3 with a frequency of fr / 4L. Each state of this output (i.e., each M-cycle) corresponds to a poll of one of the sensors by the multichannel driver 11; O (00 in binary code) - sensor 30, 1 is connected (01 in binary code) - ddtchik 4 in I drive 2 (10 in binary code) - in II, 3 (II) - in 1G1. Thus, an M-cycle is a polling cycle of all sensors.

The diagram (Fig. 4) explains the operation of the circuit during several polling cycles of the sensor 4 in the 1 accumulator, i.e., several M-cycles No. 01. Each cycle is divided into 4 cycles of the BSU (from No. 00 to No. 11 in binary code), each of which, in turn, is divided into 8M cycles, from 0 to 7 (from No. 000 to No. 111 in binary code). Each N-cycle determines the number of the memory cell 7, the contents of which are compared by circuit 14 with the number of this M-cycle (accumulator).

The reading process takes place continuously, since the readout control input of block 7 (not shown) is constantly

a resolution signal is given. In the received version of the assignment of addresses for the first four products, the following codes appear at the output of block 7: in the zero N-measure (No. 000) - 00, since nothing in the zero-number cell is recorded in connection with the fact that the score is items 19 starts from one; in 1 N-cycle (N-cycle No. 001) - 01, since the first product must be conditionally unloaded in the first drive (); in step 2 (N-stroke number 010) - 01, since the second product is also addressed to I drive (); in 3 N-tact (No. 011) - 11, since the third item was addressed to drive III (); in 4. N-tact at the output of block 7, storage device code II is 10, since the fourth product is addressed to storage device II. During the next N-strokes (5-7), the output of block 7 is the zero code (00), since the drive numbers are not recorded in these cells because, for example, the fifth and subsequent products have not yet appeared na receiving part of the conveyor.

Similarly, polling of the contents of block 7 and the next three cycles of block 10, i.e., in 1 (01), 2 (10) and 3 (11), takes place. This is shown at the top of the diagram in FIG. 4. Thus, at the output of block 7, all numbers of accumulators appear periodically in which it is necessary to unload products, and the cell number corresponds to the product number in order and number of the N-cycle, i.e., at the output of block 7, codes of numbers of drives in order of arrival on the conveyor of products addressed to them. Each N-cycle (the cycle of reading information from the cells N of block 7) is equal to one cycle of operation of block 10.

In the first such cycle, when the code at the second output of block 9 is 00, a single signal from the output "About the decimator 26 is fed to the V-input of the counter 27, i.e. the code from the output of the block 26 is written to the counter 27, during the entire cycle of operation of block 10 (M-cycle), from 3 outputs of block 9, the storage number code is supplied, in this case 01. In the initial position of the circuit in 01 cell of block 26 (as in all others) zero codes are written. Therefore, at the output of the counter 27 in the zero cycle (No. 00) of the counting and storage unit 10, there remains a zero code (000), which, having entered the input of the comparison circuit 13, is compared with the three-digit code of the N-clock numbers arriving at its second input.

A single signal at the output of the circuit 13 takes place in the case of coincidence of the codes at its inputs, i.e. in the indicated case, during the zero N-cycle (No. 000). The code at the output of block 7 is also zero (00), since no information is recorded in the zero cell (No. 000) of block 7. The code from the output of block 7 is compared with circuit 14

the number of the given M-cycle, i.e. with the code of the number of the accumulator interrogated during the given M-cycle (in this case 01). A single signal at the output of circuit 14 appears in the case of coincidence of input codes, i.e., in those N-ticks, the numbers of which are equal to the numbers of the cells in which code 01 is written (input of the first accumulator).

In this case, such a code is recorded in 1 and 2 cells (001 and 010) of block 7, therefore, a single signal at the output of circuit 14 takes place in N-ticks with such numbers, that is, in 1 and 2 N-ticks . Further, after the first N-cycle, the clock code of the BCX 10 becomes equal to 01, the signal moves from the output "On the decoder 25 to its output" 1 and flows from it to one of the inputs of the element 28; its second input is connected to the output of the imaging unit 11. In FIG. 4a shows the variant when the signal from sensor of storage number 01 is absent (equal to 0). Therefore, the output signal of the imaging unit 11 is also O, respectively, and the signal at the output of the element And 28 is equal to 0. This signal is sent to the C input of the counter I 27 and in this case does not cause a change in its state (the code 000 at the output of the counter 27 remains ). This means that in this M-clock cycle, the sensor did not trigger in the first drive. The total number of its operations is zero, i.e., no product has yet passed through the first drive.

In the next, 2 cycle of operation of block 10, the signal moves to the output of "2 decimator 25 and causes the code from the output of the counter 27 to be written to the first (01) cell of the block 26. In addition, this signal is fed to one of the inputs of element 15, i.e., if there are single signals on the remaining inputs of this element, a single signal appears at the output of the AND 15 element at the 2nd clock of block 10. However, in this case, this does not occur, since the single signals at the outputs of the comparison circuits 13 and 14 are phase shifted: the output signal of the circuit 13 appears in the zero N-cycle (000), and at the output of the circuit 14 in the first and second N-cycles (001 and 010). In addition, the absence of a single signal at the output of the imaging unit 22 in this M-cycle also does not allow to receive a single signal at the output of the element 15, In the next 3 cycle of block 10, the signal moves to the fourth output of decipheror 25 ("3) and causes the setting counter 27 to 0.

When the magnetic mark of the first product acts on sensor 4 in the I drive, a single signal appears at the output of sensor 4, which is sent to the circuit in M-cycle No. 1 (01) as a single signal with a duration equal to the duration of M tact (Fig. 2). During the M-cycle number 01, the output signal "1

Deflector 36 is supplied to one of the inputs of the element 37, the output of which appears in the presence of single signals at the remaining inputs of the element 37, i.e. in the presence of a signal from the sensor. A signal from the output of the element 37 in the zero cycle of block 10 (through the element 40) triggers a one-oscillator 38, a single signal from the direct output of which passes to the input D1 of the switch 35. Since the switch is controlled by the same code as the decoder, then the signal from input 1 in the M-cycle 01 passes to the output of the switch 35.

The duration of the output signal of the single-vibrator 38 should be equal to or slightly longer than the duration of the M-cycle. Upon termination of this signal, a one-shot 39 is started from the inverse output of the one-vibrator 38, the signal from the inverse output of which locks the And 37 element during a time-constant of the one-shot 39. This is necessary to eliminate the repeated signal from the output of the switch 35 in the next M-tick No. 01 during the first actuation of sensor 4 in storage I, since the M-cycle time is chosen to be less than the minimum signal time at the output of any of the magnetic sensors 4, such a ratio is necessary for guaranteed reception At least one signal at the output of the former 1 1 when any of the sensors is triggered during the corresponding cycle. At the same time, to avoid re-switching the signal from sensor 4 to the output of the driver (which can occur at some ratio of the phases of the beginning of the signal from sensor 4 and the beginning of the corresponding M-cycle), circuits consisting of elements 37-40 and also communication are provided output "About the de-blocker 25 of the block 10 with the inputs of the element 40 and the former 1 1 to prevent re-switching when the counter 27 is triggered. Thus, the former 11 provides a single signal when each of the sensors 4 is activated in the M-cycle, the number from It corresponds to the number of the drive in which the sensor has triggered.

When a 4-in-1 sensor is triggered (Fig. 46), the signal from the output of the imaging unit 11 causes in 1 block of block 10 the appearance of a positive front at the C input of the counter 27. The code at its output changes by 1, i.e. it will be 001 . At the output of the comparison circuit 13, a unit appears in the first N-cycle (No. 001). In the same N-cycle (Fig. 4a), the unit appears at the output of the comparison circuit 14 (since the first product is addressed to 1 accumulator), however, a single signal at the output of the AND 15 element appears only in the 2 cycle of block 10, when the resolution unit is supplied to the input of this element from the output "02 of the decoder 25.

The signal from the output of the element And 15 is fed to the control input of the descrambler 12. On

the information input of this decoder during the entire M-cycle No. 01 is supplied the code of the M-cycle number, in this case No. 01, respectively, the output of "1 decoder 12 is a single signal which, having passed through the channel of the output driver 46, triggers the executive mechanism 5 in the first drive. The first item is unloaded. In the 2nd cycle of the block, the record from the exit code of the counter 27 into the 01 cell of the element 26 occurs, i.e., the first operation of the sensor 4 in the I storage is memorized. In the next, third cycle, block 10, the counter 27 is set to 0.

Upon receipt of the second product in the I drive, the sensor 4 is triggered a second time. At the output of the driver 11 in the M-cycle No. 01, a signal appears (Fig. 4c). In the zero cycle of block 10, the code of the number of the preliminary sensor actuations in the I drive, that is, one (001), will be rewritten into counter 27 from cell 01 of element 26. In the following cycle, 1 clock cycle, one more unit is added to it, since at the C input of the counter 27 there is a positive edge caused by the presence of a signal at the output of the generator 11. In the second cycle 2, at the output of the AND 15 element there appears a single signal , which causes the appearance of a signal at the output “01 of the decoder 12 and the activation of the actuator 5 in the I drive. In the same cycle, the code of the number 2 (010) from the output of the counter 27 moves to 01 cells of the element 26, i.e., it is stored that the first two products were already in the I drive.

The next clock counter 27 is set to 0. When the sensor is triggered in the I drive the third time (Fig. 4d), a zero-step code is written to the counter of the 01 cell of element 26 (010). In the first cycle, a unit is added to this code at the C input of the counter 27. The code at its output is three (011). In the second cycle, an enable signal is supplied to the input of the element 15 from the output of the "2 decoder 25"; However, the signal at the output of the element 15 will not be, since the single signals at the outputs of the comparison circuits 13 and 14 appear in different N-clocks - at the output of the circuit 14, the signal still appears in the first and second N-clocks ( No. 001 and 010), and at the output of circuit 13 - in the third N-cycle (No. 011).

In the second cycle, the code from the output of the counter 27 (011) is rewritten into the 01 cell of the element 26. This means that there were three products in the I drive, i.e. the sensor 4 triggered three times. Upon admission to the following drive I; 4 items (FIG.), The counter 27 in the M-cycle No. 01 adds one more unit to three, i.e. it counts 4 items). In this case, the output signal in the 2 clock cycle will not be, since the output signal at the output of the comparison circuit 14 appears in 1 and 2 N-clock cycles, and at the output of the comparison circuit 13 - in the 4 N clock cycle.

Similarly, the device operates in the remaining M-cycles. In the second accumulator (M-cycle number 2 (10), the product is unloaded at the fourth sensor actuation, i.e., in 4 tact, 2 clock cycles, because a signal appears at the outputs of the comparison circuits 13 and 14. In the third accumulator in M -Tak No. 3 (11) actuation of the actuator 5 occurs at the third actuation of the sensor 4 installed in this accumulator.

In order to eliminate the possibility of the device to operate in the absence of tasks for addressing products, which can occur if the operator for some reason does not perform the task after the next product arrives at the receiving part of the conveyor, a blocking angle 41 is provided.

When the product 30 of the sensor output 30 is received from the sensor output by the single vibrator 32, a signal is generated with a duration approximately equal to the duration of the signals from the magnetic sensors 4. This signal is fed to the input "On the driver 11. The switching of this signal occurs in the M-tact number 00, i.e., the range of the sensor 30 is equivalent in this case to the presence of a “zero accumulator. As for the other accumulators, the counter 27 counts, and the cell number 00 of the element 26 stores the number of sensor 30 actuations, i.e. the number of products arriving at the conveyor.

In order to ensure the normal operation of the device, at each time point the number of tasks must exceed the number of products received on the conveyor. In the event that with the arrival of the next product, their number becomes equal to the number of tasks, in 1 step the code at the output of counter 27 becomes equal to the code at the output of counter 19. At the output of the comparison circuit 42, a single signal appears that is fed to the D input trigger 27. However, this signal is not recorded in trigger 47, since a positive edge at its C input appears earlier - at the beginning of the M-cycle number 00, i.e., at zero cycle. This product goes to the unloading according to the addressing.

When the next product enters the zone of the sensor 30 and in the absence of a task for its addressing, a code corresponding to the number of previous sensor 30 actuations, i.e. coinciding with the output code of the counter 19, is copied into the counter from the 00 cell element 26 to the counter 27. A unit appears at the output of circuit 42, which is rewritten by a signal at the C input of trigger 47. After passing from the output of trigger 47 through AND 46 to drive control unit 29, this signal stops conveyor 1.

The output signal of the comparison circuit 42 again becomes zero in the following O

ticks. However, it is not recorded in the trigger, since the sensor 30 is no longer triggered due to the stop of the conveyor. From trigger output 47, a single signal can be used to turn on sound or light signaling devices (not shown). The conveyor 1 can be started by pressing the “Start” button, i.e., a signal sent from the console to the block 29 and simultaneously removing the signal “Stop from the output trigger 47 by affecting its C input and recording, and zero from the output of the circuit 42 compare.

After the next task has run out of the capacity of counter 19, i.e. the code of the number of this task is units in all bits of counter 19, a zero code appears at the output of the next task at the output of counter 19. This product has the number 0 ... 00 and the code of its address is recorded in the cell unit 7 with the same number. Comparison of codes is made in the numbers No. 0 ... 00.

Similarly, with the next triggering of the sensors (first, sensor 30, then in order of the storage location), it is set to O and counter 27, i.e., product No. O corresponds to zero triggers of sensors in each drive. It should be borne in mind that the capacity of the counters 27 and 19 must be such that products with the same numbers could not simultaneously be on the conveyor, i.e. obviously exceed the maximum number of products that can simultaneously be on conveyor 1.
