The device works as follows.

A roll of tape is installed in the unwinding device 3. The carriage 7 is in the initial, rearmost position. A signal is present at the output of the first carriage position sensor.

The operator turns on the start-up switch and acts on the Start button 11. The signal from the output of the input switch i is fed to the first inputs of blocks 19 and 20 and to the first inputs of elements And 25 and 29t and the signal from the output of the button 11 Start goes to the second inputs blocks 19 and 23, to the third input of block 21 and to the inputs of the element OR 24, the element NOT 31 and the element OR 44.

The presence of a signal at the first and second inputs of block 19 and the absence of signals at the third and fourth inputs of the same block causes the appearance of signals at the outputs of the element OR 24 and elements 26 and 27, as well as at all the inputs of the element 25, resulting in its output is a signal that arrives at the second input of the EPI 24 element and is remembered, arrives at the output of its own block and at the first inputs of blocks 21-23, as well as at the input of the And 29 element, at the enabling inputs of the Ban 33 and the Banning element 48i The presence of a signal at the third input of block 21 is excluded t occurrence of signal on the output of NOT element 31, on vpsode AND gate 29, the output of its own unit and the drive input capture mechanism 4.

The absence of a signal at the output of the sensor 16 clamping material eliminates the appearance of a signal at the second input

block 22, at its output and at the input of the Forward Drive 8 carriage command.

The simultaneous presence of signals at the first and second inputs of block 23 causes the appearance of signals at the outputs of the BANNER 48 element, element OR 44 on one of the inputs of the AND 46 element, on the inputs of the And 47 element. The presence of signals at the same time, on both inputs of the AND 47 element the signal at its output, which is fed to the second input of the OR element 44 and is remembered and also goes to the output of its own unit: to the fifth forbidden input of the block 22 and to the input of the drive 6 of the cutting and punching mechanism, the operating mechanism is given cutting and punching ma 5.,.

After completion of the working stroke, the mechanism 5 and punching interacts with the sensor 17, as a result of which a signal appears at its input, which is fed to the fourth forbidden input of block 21 and to the fourth input of block 22. The presence of a signal at the fourth input of block 23 causes the appearance of a signal at one of the inputs of the element FDI 45, at its output, at the input of the delay element 49, at the second input of the element SH 45 and is remembered. After a predetermined time delay has elapsed at the output of element 49, a signal appears that is fed to the forbidden input of element 48, as a result of which the signal at its output disappears, at the output of element I 47, at the output of block 23, at the input of block 22 and at the input of the drive 6, after which the mechanism 5 is returned to its original position. Sensor 17 is released and the signal at its output and at the fourth inputs of blocks 22 and 23 disappears. When the SRI button is released, the signal at its output disappears, at the second input of block 23 and at the third input of block 22. The disappearance of the signal at the second input of block 23 leads to the disappearance of the signal at the outputs of the elements OR 44, AND 46, SHSh 45 and the delay line 49.

The disappearance of the signal at the third input of block 21 leads to the appearance of a signal at the output of the element 31. The simultaneous presence of signals at the four inputs of the element I causes the appearance of a signal at its output that goes to the second input

the element OR 30 is also stored, and is also fed to the output of its own unit and to the input of the drive 4, as a result of which a clamp command is given. The clamping force of the tape is adjusted with a screw, so that. It is possible to set an optimal amount of clamping force sufficient to securely clamp a tape of various thickness and prevent damage to the front surface of the material.

Simultaneously with the transmitter, an impact occurs on the sensor 16, as a result of which a signal appears at its output, which goes to the second input of block 22. The presence of signals on the first and second inputs of block 22 and the absence of a signal on its third input cause the appearance of signals on the outputs of element 33 ,, element 42, element 38. The presence of signals simultaneously on the three inputs of element 35 causes an appearance of a signal at its output, which is fed to the second input of element 27 of the box 42 and is memorized, and also arrives at the first output of its own block and the input of the command Forward of the drive 8 of the carriage and enters the forbidden I input of the circuit 34, preventing the opposite activation of the drive 8, as a result of which the command is given to the carriage of the carriage 7 with the tape gripping the clamping mechanism forward. The sensor 13 is released, the signals at its output disappear, at the third input of block 20, at the second input of block 21, at the fourth input of block 22, at the third input of element 48, at the first input of element OR 30, at the input of element HE 40 and the signal at its output at the second input of the element 37. The carriage 7, when arriving at the extreme forward position, interacts with the sensor 14, with the result that at its output a signal appears that goes to the third inputs of the block 22 and .23

The presence of a signal at the third input of block 22 causes the disappearance of signals at the outputs of the elements HE 38 and I 35, at the output of its own unit and at the input of the drive 8, with the result that the carriage 7 stops in its extreme forward position.

The presence of a signal at the third input of block 23 causes the appearance of a signal

at the output of the element ШШ, at one of the inputs of the element И 46, and at the second input of the element И 47.

The presence of a signal simultaneously on the two inputs of the element 47 causes a signal to appear at its output, at the output of its own unit, at the input of the drive 6 of the cutting and punching mechanism, and at the fifth input of the block 22.

The actuator 6, similar to the above, performs the working stroke of the cutting and punching mechanism. The presence of signals on the fifth and the absence of the fourth inputs of block 22 cause the signals at the outputs of the element HE 40, the element OR 43 and the element 37, which is fed to one of the inputs of the element 36 and the second input of the element OR 43 and is memorized.

Upon completion of the full working code, the cutting and punching mechanism acts on the sensor 17, as a result of which taTa appears at its output. the signal that arrives at the fourth inputs of blocks 21 and 23.

The presence of a signal at the fourth input of block 21 leads to the absence of signals at the outputs of the HE 32 AND 29 elements, as well as at the output of the actual block i | o and at the input of the drive 4, as a result of which the capture mechanism moves to its original idle position.

When the mechanism is moved to the initial non-working position at the output of the sensor 16 and at the point of the SHSh 42 element, the signals disappear, and the developed frame falls into the collection tray. I The presence of a signal at the fourth input of block 23 leads to the appearance of a signal at the input of the element SH-45 and at the BhropoM input of the element E 46. The presence of two signals simultaneously at the input of the element E 46 causes the appearance of a signal at its output which is fed to the second input the element OR 45 and is remembered, and also enters the input of the element 40 of the delay.

After a predetermined time out on the output of element 49, a signal appears, which is fed to the forbidden input of the element BANGE 48 B, which causes the signals to disappear at its output, at the output of element AND 47 and at its own unit, as well as at the input of the drive 6 and at the input of block 2. As a result of the disappearance of the signal at the input of the drive 6

a command is given to move to its original non-working position, while the sensor 17 is freed from the impact of the cutting mechanism and the signals disappear at its output and at the fourth inputs of blocks 21 and 23, and also releases the finished part of the belt from the rear and under the action of its own weight the belt falls down into the storage tray. The disappearance of the signal at the fifth input of block 22 causes the appearance of a signal at the output of the HE 41 element and at the wake of the AND 36 element. The presence of four signals at the output of the AND 36 element simultaneously causes the appearance of a signal at its output and at the second output of its own unit, also at the input of the Back command of the drive 8, and causes the appearance of a signal at the forbidden input of the circuit 33, preventing the opposite switching on of the drive 8, resulting in a command to move the element AND 47 BACK to the refueling zone.

The sensor 14 is released, the signals at its output disappear, at the third inputs of blocks 22 and 23, at the second input of the OR element 44, at the input of the HE element 38 and the signal appears at its output and at the third input of the AND 35 element. The carriage 7 on arrival to the rearmost initial position interacts with remote control 13, as a result of which a signal appears at its output, which goes to the third input of block 20, to the second input of block 21 and to the fourth input of block 22. The presence of a signal on the fourth the input of block 22 causes the appearance of a signal at the input of the element NOT 40 the disappearance of the signals at its output, the outputs of AND gates 37 and 36, and at the second output of its own unit and the inlet Back command actuator 8, as a result, the carriage 7 is stopped exactly at the right place. The presence of a signal at the second input of block 21 causes the appearance of signals at one of the inputs of the SHSh 30 element and at the input of the AND 29 element. The presence of signals at the four inputs of the AND 29 simultaneously causes a signal to appear at its input, which goes to the second input of the OR 30 element and is stored, as well as fed to the output of its own unit and to the input of the drive 4 of the locking mechanism. When the tape is in the refueling zone, the tape is captured in the same way as described above, after which the output of the 16 aa sensor of the material is a signal that arrives at the second input of unit 22, at the first input of the OR element D2, and at the input of the element 35. The simultaneous presence of signals at the three inputs of the element I 35 causes the appearance of a signal at its output, which is fed to the second input of the element OR 42 and is memorized, and also fed to the first output of its own unit and to the input of the Forward Drive 8 command. The carriage 7 with the clamped tape moves with forward. Then everything repeats in the same way as described in the following sequence: stopping the carriage in the outermost front position, cutting the tape, processing the back of the previous belt and processing the front of the subsequent belt, releasing the gripping mechanism of the previously processed front of the belt and feeding it in the storage tray, the completion of a pause for the final cutting of the tape, the return of the cutting mechanism to the original non-working position and the release of the rear part of the finished belt, and feed it to the accumulate flap, carriage back to the refueling area, grabbing the tape, feeding the tape a certain step forward, etc. At the end of the tape on the unwinding device, all the actuators are stopped in the initial position and the warning lamp 18 notifies the operator of the need to install a new roll of tape.

The presence of a signal at the fourth input of block 19 causes the appearance of a signal at the input of the element HE 27 and the disappearance of the signal at its output, at the output of the element I 25, as well as at the output of its own block and at the first inputs of blocks 21-23, with the result that the control system returns in the zero state, the actuators stop in the initial position, and the alarm 18 is in the on state and promptly notifies the operator of the end of the tape. The signal disappears when the input switch 10 is turned off or when refueling otochnogo device 2 and the feed belt in the cutting zone, in which the results g t T5 sensor output signal disappears, and the signals disappear

at the output of block 50, at the fifth input of block 19 and at the input of the signaling device 18, after which the control system is ready to start up the installation in automatic mode without spending time on the initial installation of actuators to the initial;

0 Thus, the use of the proposed device will eliminate the possibility of the unit idling, saving energy. The installation can work with materials of various thicknesses, which improves the quality of manufactured products.
