The count input of the trigger 62 is the count input of the link, the direct and inverse outputs of the coincidence circuit 63 are the direct and iiHBepcHbiM outputs of the link respectively. The inputs of the circuit 63 matches connected to the output of the counter 62 and to the master input level. The input of the temporary element 64 is connected to the forward output of the circuit 63 matches. The system works as follows. By command devices 9,12,18 and 19, the service personnel of the packet forming section enables and disables the drives of 7,10,14 and 15, respectively, of the transport roller table 2, turn-off device; 4, horizontal and vertical moves of the stacker 3 in the manual control mode. In the automatic control rocket, the feed of a number of 1 curved profiles to the zone of the sensor 5 is activated, the trigger 32 sequentially, the control block 8 and the drive 7 of the transport roller table 2 are successively moved by the roller table 2 to the stacker 3. The transmission cycle of row 1 in the stacker 3 is fixed by a cycle link 30 controlled by a 6 row sensor through element 29 (in the presence of a signal at its second input). After leaving p 1 and out of the zone of sensor 6, i.e. when transferring row 1 to stacker 3, by link 30 of the cycle through the OR element 31, trigger 32 is turned off and, accordingly, transport conveyor 2 is stopped. If, when transmitting each even even row 1 to stacker 3, its turn-over is necessary for 18CP, the command device 12 is set to the position at which there is no signal at its second output and at the setup input of the trigger 27. At the same time, the trigger 27 changes its state at each odd signal of the sensor 5 (at the Direct output, the signal appears and disappears at the inverse) every even signal It returns to its original state. Therefore, when entering the zone 6 of each even-numbered row, the AND 29 element does not work, but the AND 36 element turns off: and through the OR 31 trigger 32 and stopping the transport roller conveyor 2. At the same time, from the output of the 36 element, the signal is sent to the detection unit 22 step turn of the turner and to the elements And 37 and 28 of this block. In this case, the element 38 is triggered, since at its second input there is a signal from the inverse output of the flip-flop 39, and issues a command to the control unit 11 of the actuator 10 of the turn-over device 4 for turning 1 by +180. When turning on the turner 4, the control unit 11 changes its state by the trigger 39 of the unit 22, and when the next signal is applied to the unit 22 for row 1, the element 37 triggers and the row 1 turns on -180, i.e. during the return stroke, the turn-off device 4 (actuator 10 is turned on to return the turn-over device 4 to the initial state). Turning unit moves are limited with the help of sensor 13. The end of the cycle of turning of each even-numbered row 1 is recorded in block 26 determining the laying cycle by a link 33 of the cycle, which is controlled by the block-11 commands. In this case, the AND 34 element is turned on, through the OR element 35, the trigger 32 and the transport unit roller conveyor 2 for further transportation of the stranded row 1 to the stacker 3. The stacking of the rows in the stacker 3 corresponds to the stacking pattern shown in Fig. 2. After each even-numbered row 1 transfers into the stacker 3 again through element 29, the second input of which contains the signal of the link 33 of the cycle, link 30 of the cycle and element OR 31 turns off the trigger 32, stopping the roller table 2. When the transport roller table 2 is in operation, the turner 4 and vice versa, due to interlocking connections between control blocks 8 and 11. If, when laying rows 1 into stacker 3, their turning is not required, the command device 12 is set to the position at which the trigger input goes from its second output 27, the latter is permanently set in one state: there is a signal at the direct output, and there is no signal at the inverse, and the transfer of rows 1 to the stacker 3 by the roller carrier 2 is carried out without turning around, similarly to the transfer of odd rows in the above described mode. At the end of the transfer cycle of row 1, the stacker 3 from the output of the link 30 of the cycle is given a command to the block 23 of the stepping stroke of the stacker 3, which goes to the AND element 40 and the count 52. Prior to reference, link 52, given by the unit 55, the number of rows at its inverse output and at the second input of the element 40, there is a signal. In this case, the odd commands pass through the elements AND 40 and 41 and include the RS-three ger 45. The last wipe of the OR 56 element is the control unit 16 and the drive 14, the stacker 3 is turned on forwards to make a horizontal step. The pitch value is set by the counting adjuster 53 and monitored by a pulse sensor 24. After counting, the counting link 50 disables the trigger 46 and, accordingly, the actuator 14, with the horizontal step of the forward handler 3 ending. When the drive 14 is turned on, the signal from the control unit 16 changes its state by the trigger 48, so that even commands to perform a horizontal step pass through the circuit; elements 40 and 42, trigger 46, element OR 57. At the same time, the stacker 3 makes even steps back, i.e. in the opposite direction, returning to the starting position. If horizontal stacker 3 steps are not needed to form a package, and only vertical steps down are required, the command device 18 is set to the position, with which the command does not allow commands from block 23 and block 16, and the trigger 48 is reset. Commands from block 26 in this case along a chain of elements 40 and 42 and trigger 47 are only passed to control block 17 of the actuator 15 of the vertical stroke of the stacker 3. The vertical pitch is set by the setpoint 54 and monitored by the pulse sensor 25. The link 51 of the account disables the trigger 47 and stops the progress of the stacker 3 down. If the stacker performs both horizontal and vertical moves, only even-numbered commands are passed to block 17, i.e. The stacker 3 takes vertical steps down only after stacking the even rows 1. After completing the package formation in one of the pockets of the stacker 3, which is fixed by the counting link 52, commands are sent to the control unit 17 of the vertical stroke drive 15 from the output of the link 52 to stack the stacker c. the initial position and in the control unit 16 of the actuator 14 of the horizontal stroke to change pockets. The last command passes from the output of the link 52 through the elements AND 43, OR 56 or AND 44, OR 57, depending on the state of the trigger 49, which determines the direction of movement, of the stacker 3 for changing pockets. The limitation of the horizontal and vertical moves of the stacker 3 when changing pockets is performed using sensors 20 and 21, respectively. The described package formation cycle corresponds to the layout of the rows shown in FIG. The link 30 and 33 cycles are memorized using the RS flip -58 input signal, but output the signal from AND 60 only when the input signal disappears, which is fixed by the inverter 59. The time element 61 returns the trigger 58 to its initial state with a time delay after appearance of the output signal. The link 50-52 of the account counts the input signals with the help of the counter 62 and outputs the output signal from the output of the circuit 63 coincidences after the reference set by the drivers 53-55, respectively, the number of input signals. The time element 64 returns the counter 62 to its initial state with a time delay after the occurrence of the output signal. Thus, due to the addition of stacking, stepping, turner and stacker cycle units, row sensors, impulse sensors and electrical connections between them and elements of a known system, the packages are filled with profiles, the load of shop vehicles and control personnel is reduced plot.
