the outputs of the amplifiers 75i, 752, .... 75m are connected to the inputs of the element 76 OR, the output of which is the output of the reference signal generator 41.

The control unit of the brick laying machine operates as follows.

In operation of the press motor 31, the puller-tilter 2 removes from the table 3 presses a row of four bricks 36, places it on the conveyor-drive 5 (working stroke of the puller 2) and comes back (idle). At each idle of the puller-tilter 2, the conveyor belt 5 moves by means of the electric motor 31 by a distance equal to the thickness of the brick 36. As a result, space for the next row of bricks 36 is freed on the conveyor-drive 5. The puller-tilter 2 installs the bricks 36 with gaps between bricks 36 one p yes. When the puller-turner 2 is located on the press table 3, the loading sensor 1 closes, and when the puller-turning machine 2 is located on the conveyor drive 5, the unloading sensor 4 closes. When sensors 1, 4, 6, 8, 9, 10, 12, 32, 33, 34, and 35 are closed, a log signal appears at their outputs. 1, the duration of which is equal to the closure duration of the corresponding sensor. When sensors 1, 4, 6, 8, 9, 10, 12, 32, 33, 34, and 35 are opened, the output of the signal A / O appears on the outputs, disappearing when the corresponding sensor is closed. The signals from the outputs of the sensors 1 and 4 are fed to the input of the former 13 of the first counting signals, which operates similarly to the identical prototype former.

The signal 1 at the first output of the imaging unit 13 of the counting signals appears when the discharge sensor 4 closes and disappears when the loading sensor 1 closes, and the next order of the sensor 1 does not close the sensor 4 and vice versa does not change the output signals of the imaging generator 13 of the counting signals.

The signals from the first output of the imaging unit 13 of the counting signals and from the sensor 9 of the presence of the grippers 7 above the pickup point are fed to the inputs of the program block 14, which operates as follows.

When the power is turned on, the counters 48.49 are set in a known manner to the initial (zero) state. The operator, before switching on the electric motor 31 by means of push-button encoders 48, 47, enters into counters 43, 44, respectively, information on the quantities of the existing row of bricks 36 on the storage conveyor 5 and layers of brick 36 on the parquet car 11. After switching on the press 31, in the counter 48, a row of brick .36 is counted in a layer; in this case, the counting is performed when the puller 2 is on the table 3 of the press. The counting of layers of brick 36 takes place in the counter 49 when the sensor 9 for holding the grippers 7 above the pick-off point is opened. The signals from the counters 48, 49 come to the inputs of the decoder 50, at the corresponding outputs of which signals appear, for example 1, with the corresponding states of the counters 48 and 49.

In addition, at each time point, at the third output of the program block 14, there is a binary code of the number that is in counter 49 (i.e., the binary code of the layer number). When signal 1 appears at any output of the decoder 50 at the output of element 51 OR, and at the second output of program block 14, a signal H1 appears, and the counter 48 is reset. When signal 1 appears at the last output of the decoder 50 at the output of the one-shot 52, i.e. a short pulse appears at the first output of program block 14. When the 49th of the tenth signal arrives at the input, it is reset.

When signal 1 is present, at the second output of software block 14, trigger 44 is transferred to a single state and, using block 16 of electric motor 17, bricks 36 are moved to platform 37. When bricks 36 are in front of sensors 32, 33, 34, 35, signals 1, arriving at the inputs of the driver 15 stop signal, which works as follows. When appearing at the inputs of at least one signal 1, a signal 1 appears at the first output of the imaging unit 15. In this case, the trigger 44 is reset and the carrier-conveyor 5 stops. Further, in accordance with the signals from the workers, working in the same way as the prototype block of the command formation block 19, the synchronization block 18, the first

block 20 of the control is the removal and laying of a layer of bricks 36 grippers 7, trolley 29 on the trolley 11 is similar to the prototype. In the absence of at least one brick 36 in front of the sensors 32-35, when they are in front of the platform 37, there is a signal 1 at the output of the AND-NOT element 54, and a signal 1 is produced at the output of the element 55 And (i.e., at the second output of the driver 15 signal stop) arriving at the element 40 of the alarm (In the extreme range of the lack of bricks). The signal G from the first output of the stop signal generator 15 is fed through the tenth input of the first control unit 20 to the first input of element 64 I, the second input of which receives signal 1 from sensor 6 of the upper position of the grippers 7, and on the third input of which there is a signal G, air supply to the grippers 7 coming through the eleventh entrance of the second block 24 of the control. If there are signals 1 on all the inputs of element 64 I (i.e., if there are at least one brick 36 before platform 37 after air is started and the grippers 7 are raised to the upper position, i.e. after removing the brick layer from the storage conveyor 5) at its output a signal 1 appears, which enters memory register 81 and through elements OR 68 prohibiting element 71 BANKS the signal to turn on the electric motor 31 of the press (i.e. the electric motor 31 stops). The remaining elements of the first control unit 20 work similarly to the prototype and prohibit the operation of electric motors 26, 28 and 31 in the event of faults. The signal of EXTERNAL STARTING goes to the twelfth input of the first control unit 20.

From the third output of program block 14, the binary code of the number i (i-number of the layer; 1 1,

2 N) enters the shaper input

41 task signals, which works as follows.

When the binary code of the number i arrives, a control signal appears at the corresponding output of the decoder 72, and the corresponding key 74 | is triggered, and the output from the source 73 of the reference voltage appears at its output. The magnitude of the Iuz signal is selected so that when the signal is applied with the Iuz value to the electric motor 43, the platform 37 moves to the distance Lonop.

Key exit signal 74 | enters the inputs of the amplifiers 75; respectively. At the output of the amplifier 75i and the element 76 OR (i.e., at the output of the driver 41), a signal K KI appears, where Ki is the coefficient of the amplifier 75i, which is set during adjustment from the condition

platform 37 at the point of stopping the first row of bricks 36 i-layer; K - coefficient of proportionality.

The signal I41 is fed to the driver input of the control unit.

The measuring transducer 39 and the sensor 38 for horizontal movement of the platform 37 generate a signal Ise K I,

0 where I is the amount of movement of the platform 37 along the storage conveyor 5 arriving at the comparing input 5 of the control unit 42, in which the signals J41 and Ize are compared according to the result5 where the comparison gives the signal Vda to the electric motor 43, which provides a change in the position of the platform 37 ( As the signal change at the third output of the software block 14 occurs when the trolley 29 is moved to the trolley 11, then at the same moment the position of the platform 37 changes.

Thus, the supply of the control device for the brick laying machine

5 a drive platform horizontally displaced along the storage conveyor with four bricks presence sensors placed on it, a platform displacement sensor with a converter,

0 with a trigger, a stop signal conditioner, a reference signal conditioner, an alarm element and a control unit for the platform movement electric motor, improves the control accuracy.
