Description

technical field

The invention relates to a device for correcting deviation when trimming glass fiber wall cloth.

Background technique

Fiberglass wall cloth is a new type of wall decoration material made of glass fiber cloth as the base material, coated with resin and printed on the surface. It is widely used in the field of architectural decoration because of its many advantages such as various patterns, bright colors, no fading and aging when used indoors, good fire resistance and moisture resistance, and can be scrubbed. Weaving glass fiber to get glass fiber gray cloth, coloring the glass fiber gray cloth to get colored gray cloth, printing the colored gray cloth to get glass fiber wall cloth semi-finished product, and then trimming and rolling the glass fiber wall cloth semi-finished product Get the finished glass fiber wall covering. The fiberglass wall covering cutting machine for trimming the semi-finished glass fiber wall covering (abbreviated as wall covering or glass fiber wall covering in this application) does not have a correction function. When the wall covering deviates, it can only be corrected manually. The accuracy is poor, the response speed is slow, the trimming quality is not high, and it will cause a lot of waste.

Chinese patent document CN 98226313.9 discloses a horizontal shearing and feeding mechanism with a correction function for cutting paper. It has a microcomputer respectively connected to a motor and a photoelectric position sensor. Through sensor tracking and microcomputer control, the error of the sheared material is controlled within the product. within the allowable error range. However, the deviation correction function of this mechanism is not strong, the deviation correction is not accurate enough, and it is not suitable for the trimming and deviation correction of glass fiber wall cloth with high precision requirements, and if the deviation is relatively large, if the deviation is still corrected at the same speed, it will not be achieved. The results of deviation correction, coupled with the fact that the glass fiber wall cloth is smooth and the friction coefficient is small, the linear speed of the cloth will change during the transmission process. If the deviation correction speed cannot maintain a certain ratio with the real-time linear speed of the wall cloth, the deviation correction effect will not be good. would be ideal.

The rotary signal port of the programmable controller is a digital port. When selecting a special analog-to-digital and digital-to-analog converter, the analog-to-digital conversion part of the analog-to-digital and digital-to-analog converter is connected in series between the signal port of the rotary encoder and the rotary signal port of the programmable controller to The linear speed signal collected by the rotary encoder is converted into a digital signal that can be recognized by the programmable controller.

In the left and right directions, when the cutter is at the center of the left limit switch and the right limit switch, the center of the first color mark sensor on the left and the first color mark sensor on the right is located outside the cutter .

The present invention can bring following beneficial technical effect:

(1) When the device of the first scheme of the present invention (abbreviated as the first device) is in use, the position information of the detected color line is transmitted to the programmable controller by the color mark sensor, and the programmable controller outputs the execution command again To the frequency converter, the frequency converter controls the rotation of the executive motor to adjust the trimming position of the cutter. When the device of the second solution of the present invention (abbreviated as the second device) is in use, the color mark sensor transmits the position information of the detected color line to the programmable controller, and the programmable controller outputs an execution command to the frequency converter , the actuator motor is controlled by the frequency converter to adjust the position between the winding frame, the wall cloth and the sensor frame by moving the winding frame. Since the distance between the sensor frame and the winding frame is 2.5 meters to 5 meters (corresponding to the wall cloth running The line speed is 8 meters to 30 meters), so that this adjustment can be carried out efficiently. Therefore, these two devices can automatically control the deviation correction during edge trimming, which not only improves the degree of automation, but also cuts accurately during edge trimming, improving product quality and work efficiency.

(2) When two kinds of device control systems of the present invention adopt 2 color mark sensors, then this signal is sent to programmable controller immediately when one of them color mark sensor detects color mark signal in the work, and programmable controller According to the position of the left and right sides of the color mark sensor, the control execution system makes the cutter move a certain distance in the same direction as the wall cloth offset direction during cutting, or controls the execution system so that the winding frame drives the wall cloth during winding. Move a distance in the direction opposite to the direction in which the wall covering is offset. The size of the distance is half of the distance between the two color mark sensors; during the continuous advancement of the wall cloth, if deviation occurs, one of the photoelectric eyes as the color mark sensors on both sides detects the color mark signal , the deviation is corrected under the control of the programmable controller.

(3) When the two device control systems of the present invention adopt the scheme of setting the middle color mark sensor, then the middle color mark sensor can be used as the reference color mark sensor, if the color line of the wall covering is just in the middle color mark sensor when starting Down, it means that edge trimming is possible. Once the wall covering deviates during travel, after the programmable controller receives the signal of the first color mark sensor on the left or the first color mark sensor on the right, it will control The execution system makes the execution motor (also known as the correction motor) rotate to make the cutter move a certain distance in the same direction as the wall cloth offset direction during cutting, or control the execution system so that the winding rack drives the wall cloth to the same direction as the wall cloth during winding. Move a distance in the direction opposite to the offset direction of the wall covering. The distance is the distance between two adjacent color mark sensors. This control method, on the one hand, makes the detection by the color mark sensor more accurate, and on the other hand, it also makes the control of the programmable controller more convenient and simple.

(4) When the first device is used and the sensor frame is fixedly connected with the screw nut block of the knife frame, the sensor frame can move along with the movement of the tool frame. Under this scheme, if the intermediate color mark sensor is used again, there are two ways to correct the deviation. No matter which method, because a color mark sensor on the left or right side receives the corresponding color mark signal (which can be collectively referred to as the deviation signal), it can then judge the direction of the deviation, so that the programmable controller can judge the deviation After the direction, the command to control the motor to rotate in the corresponding direction is issued. In the first method, because the distance between adjacent sensors is known in advance, the distance can be used as the distance of deviation, and because the rotation speed of the motor must be set when correcting the deviation, so when the programmable controller is related When setting the control value, you can list the corresponding relationship between the deviation distance and the motor rotation speed and rotation time. After converting this corresponding relationship into the corresponding relationship between voltage and time, you can set the relationship between voltage and time. Another method is to only need to control the rotation speed of the execution motor. If the induction signal from the middle color mark sensor is detected during the deviation correction process, the rotation of the execution motor will be stopped immediately. Because the latter method does not need to select the rotation time after the motor speed is determined, so it is simpler and more accurate.

(5) When the two device control systems of the present invention adopt the scheme of 4 or 5 color mark sensors, the programmable controller is also set to receive the first color mark sensor on the left side and the first color mark sensor on the right side. The color mark signal of the mark sensor (belonging to the deviation signal) is used as a signal to control the cutter or the winding frame to move at a low speed, and the received color mark signal of the second color mark sensor on the left side and the second color mark sensor on the right side ( It also belongs to the deviation signal) as a signal to control the high-speed movement of the cutter or the winding frame. This control method can make the deviation correction range wider and more accurate, and when the wall cloth deviation is large, it can quickly perform deviation correction control and obtain Very good correction effect.

(6) When the two devices of the present invention use rotary encoders, the data of the linear velocity of the wall covering can be detected during use. After the data is sent to the programmable controller, the programmable controller can A certain proportional value between the deviation correction speed and the wall wiring speed, after calculating the required rotation speed of the executive motor, the required deviation correction speed command is sent to the frequency converter, and the frequency converter controls the execution motor to make the cutter at a certain speed Or the winding frame moves to the corresponding position at a certain speed, so as to realize real-time detection and control; and the moving speed of the cutter or the winding frame matches the linear speed of the wall cloth, so that the wall cloth can be moved at different linear speeds. The technical effect of reliable trimming is achieved in the process.

(7) After the first device of the present invention is provided with a limit switch, when the wall cloth is traveling a large distance away from the center position and the slider of the knife rest touches the limit switch, the programmable controller receives the signal Finally, the control equipment will alarm and shut down, and the wall cloth will be corrected and placed in the correct position manually, and then the system will be restarted, which will help ensure the safety of production operations and product quality. On the basis of this selection, in the direction of the left and right sides, when the cutter is in the middle position between the left limit switch and the right limit switch, the first color mark sensor on the left and the first color mark sensor on the right are selected. The central position between the color code sensors is positioned at the outside of the cutter, and a certain value can be selected in 2, 3 or 4 warp yarn spacings for these two central positions. When this structure is adopted, it can be ensured that the color line part is cut off during the trimming process of the wall cloth.

(8) After the two devices of the present invention are provided with manual and automatic function changeover switches, the conversion between manual operation and automatic operation can be performed to adapt to different operating situations.

(9) When the two devices of the present invention also include a man-machine control device, man-machine dialogue can be performed during use, trimming parameters can be set according to the trimming process requirements, and the working status can also be displayed and monitored.

(10) The two devices of the present invention are exquisitely designed, and the software and hardware used are common, so the cost is low and the operation is simple. The control of the programmable controller makes the deviation correction precision high, and the deviation correction performance is stable and reliable, thereby greatly reducing edge trimming errors rate, improve the input-output rate of glass fiber wall cloth.

Detailed ways

The electronic deviation correction device for edge trimming of glass fiber wall cloth according to the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

The distance between each color mark sensor is the warp distance of the wall cloth, which varies with the specifications of the wall cloth. For example, when the warp distance is 1.25mm (or 2.5mm, etc.), the distance between adjacent sensors is 1.25mm. In the following embodiments, the distance between adjacent sensors is 1.25 mm as an example. When the fiberglass wall cloth cutting machine is in use, the wall cloth 8 is trimmed horizontally or vertically according to its structure.

(Example 1)

See Fig. 1 to Fig. 3, in this embodiment, the electronic deviation correction device for edge trimming of glass fiber wall cloth is composed of a control system and an execution system.

Referring to Fig. 1 and Fig. 2, the execution system includes an execution motor frame 11, a slider frame 12, a sensor frame 13, a knife frame 2, an execution motor 3, a screw rod 4 and a cutter 5.

In the execution system, the actuator frame 11 and the slider frame 12 are fixed structural parts during use. The specific structure is: the frame of the glass fiber wall cloth cutting machine is fixed with a gantry-shaped installation frame, the slide bar frame 12 is fixed on the installation frame and is located above the wall cloth 8, and the executive motor frame 11 is also fixed on the glass fiber wall cloth cutting machine. machine rack. There is no direct connection between the slide bar frame 12 and the actuator frame 11, and the slide bar frame 12 is arranged horizontally.

The tool holder 2 has a slide block 21 and a nut block 22 . The slider 21 is divided into a left slider 21-1 and a right slider 21-2. The left slide block 21-1 and the right slide block 21-2 are fixedly connected with the nut block 22. The slide block 21 of the knife rest 2 is slidably connected with the slide bar frame 12 . The sensor frame 13 is fixedly connected with the nut block 22 of the knife rest 2, and can move in the same direction as the knife rest 2 at the same time.

The executive motor 3 is fixed on the executive motor frame 1 by its motor housing, the motor shaft of the executive motor 3 transmits power to the right end of the screw rod 4 through the transmission mechanism, and the left end of the screw rod 4 is threaded with the nut block 22 of the tool holder 2 to rotate connect.

Above-mentioned transmission mechanism is made up of motor synchronous belt pulley 31, synchronous belt 32, screw mandrel synchronous belt pulley 33. Motor synchronous pulley 31 is fixed on the motor shaft, screw mandrel synchronous belt 33 is fixed on the right end of screw mandrel 4, and synchronous belt 32 is arranged around motor pulley 31 and screw mandrel synchronous belt 33, and simultaneously with motor pulley 31 and screw mandrel The timing belt 33 is meshed.

The cutting knife 5 is fixed on the knife rest 2 and is arranged according to the wall covering 8 with the edge of the knife facing downwards during use. In the present embodiment, there are 2 cutting knives 5 (only the cutting knife 5 on the right side of the nut block of knife rest 2 is drawn in the figure), all of which are fixed on the nut block 22 of knife rest 2, located on the right side. The side cutter 5 cuts the right edge of the wall cloth 8, while the left cutter cuts the left edge of the wall cloth 8, and the distance between the two cutters is constant. Therefore, as long as the position of one of the two cutting knives is adjusted relative to the wall cloth 8, simultaneous cutting of the edges on both sides of the wall cloth 8 can be realized.

See FIG. 3 , the control system includes a color mark sensor 91 , a man-machine control device 92 , a programmable controller 93 , a frequency converter 94 , a rotary encoder 95 and an analog-to-digital and digital-to-analog converter 97 . There are five color mark sensors 91 in the present embodiment.

In the control system, the color mark sensor 91 is a sensor for sending out a signal of whether the color line 81 of the wall covering it faces is located directly opposite to itself when in use. The color mark sensor 91 is fixed on the sensor frame 13. When in use, it is arranged on the same plane facing and parallel to the wall cloth 8 in order from left to right, and the signal output terminal of the color mark sensor 91 is connected to the programmable controller. 93 position signal input.

The signal shaft of the rotary encoder 95 of the control system is fixedly connected with the wall cloth conveying roller 6; the rotary signal port of the programmable controller 93 is a digital port. The analog-to-digital conversion part of the analog-to-digital and digital-to-analog converter 97 is connected in series between the signal port of the rotary encoder 95 and the rotary signal port of the programmable controller 3, for converting the linear velocity signal collected by the rotary encoder 95 into A digital signal that can be recognized by the programmable controller 93; the motor control signal port of the output end of the programmable controller 93 is connected to the corresponding port of the control end of the frequency converter 94, and the frequency conversion control signal port of the output end of the programmable controller 93 is passed through the modulus and digital The digital-to-analog conversion part of the analog-to-analog converter 97 is connected to the frequency conversion setting signal input end of the frequency converter 94; The man-machine control device 92 is bidirectionally electrically connected with the communication port of the programmable controller 93 through its communication port.

See Fig. 2 and Fig. 5, on the right side of the wall cloth 8 along the edge direction at the edge of the wall cloth 8, insert a color line that exposes the upper surface of the wall cloth 8 as the color code 81, the color can be selected (such as black), It can be distinguished from the original color of the wall covering. The color mark sensor 91 is a monochromatic light source sensor, which emits a light beam, and then realizes the detection of the position of the color line 81 by detecting that the reflection amount of the light beam by the color line 81 is different from that of the surrounding wall cloth warp yarns.

Still referring to FIG. 2 and FIG. 5 , the color mark sensor 91 of this embodiment is fixed on the sensor bracket 13 . Among these 5 color mark sensors 91, with the color mark sensor 91-1 in the middle as the benchmark, there are two left and right respectively, the left side is the color mark sensor 91-2, 91-4, and the right side is the color mark sensor 91-3, 91-5. .

Still see Fig. 2 and Fig. 5, when the wall covering 8 has offset, the color line 81 embedded on the wall covering 8 will also have offset, when the first color mark sensor 91-2 on the left side, the second color mark sensor 91-2 on the left side When the mark sensor 91-4 detects the color line 81, it means that the wall covering is 1.25mm or 2.50mm to the left. After receiving the corresponding color mark signal, the programmable controller 93 instructs the frequency converter 94 to control the execution motor 3 to rotate counterclockwise. direction to rotate a certain angle (observed from the motor shaft rear), thereby controlling the cutter 5 to move to the left by 1.25mm or 2.50mm to realize deviation correction, and when the right side color mark sensors 91-3, 91-5 detect the color line 81 , indicating that the wall covering is 1.25mm or 2.50mm to the right. After receiving the corresponding color code signal, the programmable controller 93 instructs the frequency converter 94 to control the execution motor 3 to rotate a certain angle clockwise, thereby controlling the cutter 5 Move 1.25mm or 2.50mm to the right to achieve skew.

For the device in which the middle color mark sensor 91-1 is set in this embodiment, when the programmable controller 93 is set, a more convenient method can be adopted: that is, if a deviation occurs, such as a deviation to the left, the programmable controller 93 can be programmed. The controller 93 then controls the motor so that the knife rest 2 drives the cutter 5 and the sensor frame 13 to move to the left together. Once the middle color mark sensor 91-1 sends an induction signal that detects the color line 81, the programmable controller 93 controls it immediately. The actuator motor 3 is stopped from rotating, instead of realizing deviation correction by controlling the rotation angle of the actuator motor 3 as described above.

See Figure 3, the control system adopts closed-loop control mode. When any color mark sensor 91 detects the color line 81, the position information of the color line 81 is sent to the programmable controller 93, and after calculation, the programmable controller 93 outputs a correction command to the frequency converter 94, and the frequency converter 94 then By controlling the execution motor 3, the cutting knife 5 moves to a certain position during cutting to perform deviation correction.

The rotary encoder 95 connected with the wall cloth conveying roller 6 is used to detect the linear speed of the wall cloth, and feeds back the speed data to the programmable controller 93. After calculation, the output speed control command is sent to the execution motor 3 through the frequency converter 94 to control The moving speed of the cutter 5 ensures that the ratio between the deviation correction speed and the wall wiring speed is constant. For example, when the linear speed of a regular cloth is 0.8 meters per minute, the deviation correction speed of the device is 0.003 meters per minute, and when the cloth speed is 12 meters per minute, the deviation correction speed is 0.045 meters per minute. If the offset distance is relatively large, that is, when the color mark sensor 9m-4, 91-5 detects the color line 81, the speed will be multiplied by a coefficient, which can be set in the man-machine control device 92, such as this coefficient If it is 2, that is, when the linear speed of the wall cloth is 0.8 meters per minute, the deviation correction speed is 0.006 meters per minute, and when the cloth speed is 12 meters per minute, the deviation correction speed is 0.090 meters per minute.

Referring to Fig. 1 and Fig. 4, the signals sent by the left and right four color mark sensors 91 are processed by the programmable controller 93 as different speed signals. The color mark signals of the first color mark sensor 9m-2 on the left side and the first color mark sensor 9m-3 on the right side are used as low-speed deviation correction signals by the programmable controller 93, and the second color mark sensor 91-4 on the left side and the first color mark sensor 91-4 on the right side The color mark signals of the two color mark sensors 91-5 are used by the programmable controller 93 as high-speed deviation correction signals. In this way, when the wall cloth deviates greatly, the programmable controller 93 controls the actuator motor 3 to rotate at a faster speed to make the cutter 5 move at a faster speed to quickly correct the deviation. In this way, through the setting of 5 color mark sensors, it is possible to realize accurate deviation correction of four deviation positions on the left and right, and to select an appropriate speed for deviation correction under different deviation distances.

During the left and right movement of the cutter 5 and the slider 21 driven by the nut block 22, when the left slider 21-1 touches the left limit switch 99-1 or the left slider 21-2 touches the right limit When switching 99-2, it means that the cutter 5 has exceeded the reasonable cutting range, so the equipment will alarm and shut down to ensure production safety.

For example, if the voltage value to be input to the frequency converter 94 is 8V, then the corresponding frequency value is 40Hz, and the programmable controller 93 transmits the digital quantity corresponding to the digital quantity of 40Hz corresponding to the voltage 8V to the analog-to-digital and digital-to-analog converter 97 , the analog-to-digital and digital-to-analog converter 97 provides a high-precision, high-resolution 8V voltage to the frequency converter 94 . The voltage value output from the programmable controller 93 to the AVI port of the frequency converter 94 after being converted by the analog-to-digital and digital-to-analog converter 97 is a certain value from 10V to 0V. The frequency of the 94 output current is also high, and the rotating speed of the motor is also fast. When the output voltage is 0V, the motor stops rotating. The voltage value is determined by the current linear velocity at which the above-mentioned wall cloth 8 moves forward. When the sensor frame 13 moves to the middle color mark sensor 91-1 and sends a detection signal along with the movement of the knife frame 2, then the programmable controller 93 sends a signal to stop the motor from rotating.

The color mark sensors 91 - 4 , 91 - 2 , 91 - 1 , 91 - 3 , 91 - 5 transmit the detected color line position signals to the programmable controller 93 . Taking the 1.25mm warp spacing as an example, now the color mark sensor distance is also 1.25mm. When the color mark sensor 91-1 detects the color line 81, it means that the trimming position is accurate, and the cutter 5 is in the normal trimming state. When the indicator light 911-2 is on; when the color mark sensor 91-2 or 91-4 detects the color line 81, it means that the wall covering has shifted to the left by 1.25mm or 2.50mm, and the indicator light 911-1 is on At this time, the programmable controller 93 needs to control the cutter 5 to move to the left by 1.25mm or 2.50mm, and reach the correct cutting position to realize deviation correction; when the color mark sensor 91-3 or 91-5 detects the color line 81, Indicates that the wall covering has deviated to the right by 1.25mm or 2.50mm during the progress, and the indicator light 911-3 is on. At this time, the programmable controller 93 needs to control the cutter 5 to move to the right by 1.25mm or 2.50mm, so as to reach the correct cutting position. Implement correction. When cutting knife 5 exceeds reasonable range and contacts with limit switch 99-1 or 99-2, after programmable controller 93 receives this signal, then control indicator light 911-4 is bright, and by alarm 912 reports to the police.

During the advancing process of the wall covering 8, the rotary encoder 95 continuously sends the detected linear velocity signal of the wall covering to the analog-to-digital and digital-to-analog converter 97, which is converted into The digital signal that can be recognized by the programmable controller 93 is then sent to the programmable controller 93 .

Once the cutter 5 deviates from the cutting position, the programmable controller 93, on the one hand, outputs corresponding control commands to the frequency converter 94 from the motor control signal port at its output end to control the execution motor according to the distance and direction of the deviation. 3 start, and also select whether to reverse and accelerate, thereby controlling the moving direction of the cutter 5 and whether to accelerate the movement.

On the other hand, under the premise that there is no acceleration rotation control signal in the control signal output by the motor control signal port at the output end of the programmable controller 93, according to the digital signal of the linear velocity of the wall cloth 8, the ultimate goal is to control the execution. The corresponding digital signal of the rotational speed of motor 3 is input to the digital-to-analog conversion part of analog-to-digital and digital-to-analog converter 97 by its frequency conversion control signal port again, and analog-to-digital and digital-to-analog converter 97 then converts this digital signal into phase The corresponding voltage signal is input to the frequency conversion setting signal input terminal of the frequency converter 94, and the frequency converter 94 can output power with a set frequency at its power output terminal according to the voltage signal.

If the programmable controller 93 receives the signal of the left first color standard sensor 91-2, the programmable controller 93 makes the contacts between the port Y0 and the port COM0 and between the port Y1 and the port COM0 conduct on the one hand. , so that the external circuit between the port M3 and the port DCM of the frequency converter 94 and the external circuit between the port M2 and the port DCM are conducted, thereby controlling the motor 8 to start reverse rotation. On the other hand, the programmable controller 93 outputs a control signal for controlling the rotational speed of the motor from its frequency conversion control signal port, so that the frequency of the current input to the actuator 3 is the set frequency. When the executive motor 3 rotates to the middle sensor 91-1 on the sensor frame 13 and detects the colored line 81, the control of the programmable controller 93 will break the contact between its port Y0 and the port COM0 and between the port Y1 and the port COM0. Open, so that the actuator motor 3 stops rotating, and the control signal is no longer output from its frequency conversion control signal port.

If the programmable controller 93 receives the signal of the second color mark sensor 91-4 on the left side, the programmable controller 93 does not output the control signal at its frequency conversion control signal port, but only outputs the signal at the motor control signal port at its output end. That is, only the internal contacts between the port Y0 and the port COM0, between the port Y1 and the port COM0, and between the port Y2 and the port COM0 are conducted, so that the external circuit between the port M3 end and the DCM end of the frequency converter 94 , the external circuit between the port M2 end and the DCM end and the external circuit between the port M1 end and the DCM end are turned on, thereby controlling the frequency converter 94 to output a current with a certain frequency and a high value, so that the motor 3 can be set at a certain frequency. reverse rotation at a faster speed. When the programmable controller 93 receives the color mark signal of the first color mark sensor 91-2 on the left side, the programmable controller 93 just disconnects the internal connection between the port Y2 and the port COM0; at the same time, the programmable controller The frequency converter 93 outputs a frequency conversion control signal corresponding to the linear speed of the wall cloth at its frequency conversion control signal port, so that the frequency converter 94 receives a voltage signal related to the linear speed of the wall cloth, and adjusts the frequency of the output current by the voltage signal And control the rotational speed of motor 3 (the highest value of this speed is set as half of the faster speed of above-mentioned determination); When the frame 2 moves and moves to the signal sent directly above the colored line 81, the contact between the port Y0 and the port COM0 and between the port Y1 and the port COM0 is controlled to be disconnected, so that the execution motor 3 stops rotating and does not Then output the control signal from its frequency conversion control signal port. If the programmable controller 93 receives the signal of the first color mark sensor 91-3 on the right side, its working process is similar to the signal receiving the first color mark sensor 91-2 on the left side, mainly in the programmable controller 93 When controlling the control end of the frequency converter 94, the reverse port Y1 does not participate in the control process.

If the programmable controller 93 receives the signal of the second color mark sensor 91-5 on the right side, its working process is similar to receiving the signal of the second color mark sensor 91-4 on the left side, mainly controlled by the programmable controller 93 When the control terminal of the frequency converter 94, the reverse port Y1 does not participate in the control process.

The speed moves to the left by 0.625mm to reach the correct cutting position to achieve deviation correction; when the first color mark sensor 91-3 on the right detects the signal of the color line 18, it means that the wall covering has shifted to the right by 0.625mm during travel Therefore, at this time, under the control of the programmable controller 93, the cutting knife 5 is moved to the right by 0.625 mm at a moving speed corresponding to the advancing linear speed of the wall cloth 8 to reach the correct cutting position and realize deviation correction.

The method for correcting deviation in embodiment 9 to embodiment 12 is the same as the corresponding embodiment

(Example 13)

See Fig. 8 to Fig. 10, this embodiment is the second realization scheme of the present invention, in the figure, the wall cloth on the glass fiber wall cloth cutting machine is arranged in a horizontal manner. The electronic deviation correction device in this embodiment is still composed of a control system and an execution system. The control system is the same as in Embodiment 1, the difference is that the left limit switch 99-1 and the right limit switch 99-2 are arranged on the wire On the rod 4, or on the guide rail 15, this embodiment adopts a different execution system when correcting the deviation.
