Description
Technical Field
[0001] The utility model relates to the technical field of pre-coated metal coil production equipment, in particular to an on-line deviation rectifying device for pre-coated metal coils. Background Art
[0002] The processing and production of pre-coated metal coils are generally continuous production. The distance from uncoiling to coiling is relatively long and various equipment needs to be passed through on the way. If the shape of the pre-coated metal coil is good and the cross-section is uniform in thickness, the tension distribution acting on the pre-coated metal coil is uniform. At the same time, each roller is kept parallel and perpendicular to the running direction of the pre-coated metal coil. Then, the pre-coated metal coil will not deviate when running on the roller, that is, the pre-coated metal coil always runs at the center of the production line. However, in the actual production process, various factors will affect the normal running track of the pre-coated metal coil. Therefore, the deviation phenomenon is very easy to occur in the actual production process. Generally, a deviation rectifying device is set on the production line. At present, the traditional control method uses a deviation rectifying roller and a hydraulic cylinder, which requires a supporting hydraulic system, and the device itself is relatively large and requires a certain installation space. In addition, the deviation rectifying device is of customized size, and different widths of deviation rectifying devices correspond to different widths of coils. Its customization and installation costs are high, and the later maintenance cost is relatively large. The existing deviation rectifying device lacks automation in the operation mode and has a long reaction time, and it cannot play the function of preventing deviation monitoring. It is very inconvenient to use, and it is very easy to cause the strip to deviate, resulting in the scrapping of raw materials; the hydraulic system is prone to oil leakage during long-term operation, causing environmental pollution, and the production and use costs of the hydraulic system are relatively high, and the maintenance is also relatively cumbersome.
[0003] The technical problem to be solved by the utility model is to provide an on-line deviation rectifying device for pre-coated metal coils, which uses an infrared sensor to collect the deviation distance of the pre-coated metal coil online, and through the control system interlock control, the electric driver of the deviation rectifying roller generates a signal for left and right movement to adjust the deviation of the coil, and pre-emptively corrects the deviation of the metal coil. It is simple and flexible to operate, low in cost and strong in controllability. Summary of the Invention
[0004] The purpose of the utility model is to provide an on-line deviation rectifying device for pre-coated metal coils that is simple and flexible to operate. The device sets the deviation rectifying roller on the moving slide, and the moving slide can slide on the slide rail to flexibly adjust the distance between the coils in the width direction, adapting to the continuous production of pre-coated metal coils with different widths. And it can judge the deviation condition of the pre-coated metal coil by real-time monitoring of the edge deviation distance of the pre-coated metal coil. When the alarm of the edge deviation distance of the pre-coated metal coil occurs, the deviation of the pre-coated metal coil running online is adjusted through the monitoring interlock feedback control system, which can effectively prevent the metal coil from running off-line and rectify the deviated metal coil to the right track. On the other hand, it reduces the generation of coil waste, prevents unsafe behaviors in the production process, effectively improves the operation efficiency of the production line, and reduces the maintenance cost.
[0005] The present utility model is achieved by the following measures:
[0006] An on-line deviation rectifying device for pre-coated metal coils, comprising an infrared sensor, a deviation rectifying roller, a moving slide, a slide rail, a machine base, a bracket and a control system. The deviation rectifying roller is installed on the moving slides on both sides in the width direction of the coil. The moving slides are installed on the slide rail, and the slide rail is fixedly installed on the machine base. The bracket is fixed above the pre-coated metal coil production line. The infrared sensor is fixedly installed on the bracket. The infrared sensor uses the optical principle to perform on-line real-time monitoring on the edge of an object, and adjusts the deviation of the on-line operation of the pre-coated metal coil through the monitoring interlock control system, and controls the on-line deviation of the pre-coated metal coil within the threshold range.
[0007] The moving slides and the deviation rectifying rollers are arranged in pairs on both sides in the width direction of the coil. The production adaptation width of the pre-coated metal coil is adjusted by moving the moving slides on the slide rail to adapt to pre-coated metal coils of different widths. The surface of the deviation rectifying roller is chrome-plated, and the number is 1 to 3.
[0008] The deviation rectifying roller is driven by an electric driver to drive the left and right movement of the pre-coated metal coil to achieve the purpose of deviation rectification. The electric driver of the deviation rectifying roller is electrically connected to the control system to form a loop control system for on-line monitoring and deviation rectification.
[0009] The infrared sensors are arranged on both sides of the width edge of the pre-coated metal coil. The direction of the detection light source points perpendicular to the plate surface of the pre-coated metal coil. The vertical distance is 10 to 300 mm, and the distance from the edge in the width direction of the pre-coated metal coil is 0 to 10 mm.
[0010] The infrared sensor mainly monitors the deviation distance of the edge of the pre-coated metal coil. When the monitored edge deviation distance ≥ 50 mm, it is a long limit value alarm. When the monitored edge deviation distance ≥ 150 mm, it is a long and long limit value alarm. The infrared sensor performs on-line monitoring on the width edge distance of the pre-coated metal coil, and the monitoring data is fed back to the control system in real time. When the infrared sensor gives a long limit value alarm, the alarm is fed back to the control system, and the control system rectifies the metal coil to the correct path through the on-line deviation rectifying device. When the infrared sensor gives a long and long limit value alarm, the alarm is fed back to the control system, and the control system performs an emergency stop through the start-stop system.
[0011] The on-line deviation threshold range of the pre-coated metal coil is ≤ 50 mm.
[0012] The on-line deviation rectifying device is suitable for pre-coated metal coils with a width of 0.5 to 2.2 m, and generally preferably 0.6 to 1.8 m.
[0013] The beneficial effects of the present utility model are as follows: An online deviation rectification device for pre-coated metal coils provided by the present utility model utilizes a deviation rectification roller arranged on a movable sliding seat. The movable sliding seat can slide on the slide rail to flexibly adjust the distance in the width direction of the coil, adapting to the continuous production of pre-coated metal coils with different widths, reducing the customization cost. An infrared sensor is used to collect the deviation distance of the pre-coated metal coil online. By interlocking the sensor data with the electrical signal of the electrical drive of the deviation rectification roller, and through the control system to analyze and process the sensor data and feedback to the electrical drive of the deviation rectification roller, a signal for left and right movement is generated to adjust the deviation of the coil, preventing and correcting the deviation of the metal coil in advance. The operation is simple and flexible, with low cost and strong controllability. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] To clearly illustrate the technical features of this solution, the following will elaborate on this solution through specific embodiments.
[0024] See Figures 1 to 4 , an on-line deviation rectifying device for pre-coated metal coils, comprising an infrared sensor 1, a deviation rectifying roller 2, a moving slide 3, a slide rail 4, a machine base 5, a bracket 6, and a control system 7. The deviation rectifying roller 2 is installed on the moving slides 3 on both sides in the width direction of the coil. The moving slides 3 are installed on the slide rail 4, and the slide rail 4 is fixedly installed on the machine base 5. The bracket 6 is fixed above the production line of the pre-coated metal coil 8. The infrared sensor 1 is fixedly installed on the bracket 6. The infrared sensor 1 uses the optical principle to perform on-line real-time monitoring on the edge of an object, and adjusts the deviation of the on-line operation of the pre-coated metal coil 8 through the monitoring and interlocking control system, and controls the on-line deviation of the pre-coated metal coil 8 within the threshold range.
[0025] See Figure 2As shown, the movable slide 3 and the deviation rectifying roller 2 are arranged opposite to each other on both sides in the width direction of the coil. By moving the movable slide 3 on the slide rail 4, the production adaptation width of the pre-coated metal coil 8 is adjusted to adapt to pre-coated metal coils 8 of different widths. Generally, the width of the pre-coated metal coil 8 adapted is 0.5 - 2.2 m. The surface of the deviation rectifying roller 2 is chrome-plated to increase the surface hardness and prevent mechanical wear. The number of the deviation rectifying rollers 2 is 1 - 3, and generally 3 are preferred.
[0026] Furthermore, the deviation rectifying roller 2 is driven by an electric driver 201 to drive the left and right movement of the pre-coated metal coil 8 to achieve the purpose of deviation rectification. The electric driver 201 of the deviation rectifying roller 2 is electrically connected to the control system 7 to form an on-line monitoring and deviation rectifying loop control system.
[0027] See Figure 3 As shown, the infrared sensors 1 are arranged on both sides of the width edges of the pre-coated metal coil 8. One group consists of two modules, which are composed of a group of lenses and reflectors. Among them, the lens module is aligned and installed at the front position of the pre-coated metal coil 8, that is, installed on the top beam of the bracket 6, and the reflector module is symmetrically installed on the reverse side of the pre-coated metal coil 8, that is, installed on the lower cross beam of the bracket 6. The lens module and the reflector module are symmetrically installed in the upper and lower positions of the pre-coated metal coil. One group is installed on each of the left and right sides during the operation of the pre-coated metal coil 8, and the edge image of the object can be focused on the sensing chip. The sensing chip is a highly integrated optoelectronic conversion element, which can convert the image focused on it into an electrical signal, and then process and analyze the electrical signal through digital signal processing technology to obtain the edge position information of the object. The direction of the detection light source is perpendicular to the plate surface of the pre-coated metal coil 8, and the vertical distance is 10 - 300 mm, and the distance from the edge in the width direction of the pre-coated metal coil is 0 - 10 mm.
[0028] See Figure 4 As shown, the infrared sensor 1 mainly monitors the edge offset distance of the pre-coated metal coil 8. When the monitored edge offset distance ≥ 50 mm, it is a long limit value alarm. When the monitored edge offset distance ≥ 150 mm, it is a long long limit value alarm. The infrared sensor 1 conducts on-line monitoring of the width edge distance of the pre-coated metal coil 8, and the monitoring data is fed back to the control system in real time. When the infrared sensor 1 gives a long limit value alarm, the alarm is fed back to the control system 7, and the control system 7 rectifies the metal coil to the correct track through the on-line deviation rectifying device. When the infrared sensor 1 gives a long long limit value alarm, the alarm is fed back to the control system 7, and the control system 7 performs an emergency stop through the start-stop system. This deviation rectifying device mainly controls the on-line deviation threshold range of the pre-coated metal coil 8 within 50 mm to prevent the large deviation of the pre-coated metal coil 8, so as to ensure that the pre-coated metal coil is always in good conveying and transmission and avoid production accidents such as deviation and material throwing.
[0029] In actual application, first, the pre-coated metal coil 8 is conveyed from the front uncoiling mechanism. Then, the infrared sensor 1 detects the offset distances of the left and right edges of the conveyed pre-coated metal coil 8 in the running direction. The detection data is fed back to the control system. When the detection data is within the normal threshold range, the pre-coated metal coil 8 is conveyed normally. At this time, the deviation rectifying roller 2 is used as a conveying roller. However, when the detected data feeds back that the edge offset distance ≥ 50 mm, that is, when the set long limit value alarms, the control system 7 processes an electrical signal for the electric driver 201, controls the electric driver 201 to push and pull the deviation rectifying roller 2 left and right, and adjusts the edge offset distances on both sides of the pre-coated metal coil 8 to make it within the normal threshold range. And when the offset distance of the pre-coated metal coil 8 suddenly exceeds 150 mm, that is, when the set extra long limit value alarms, at this time, the control system 7 shuts down the production line emergently, which is the emergency treatment. Generally, before the extra long limit value alarms, the on-line deviation rectifying device will predict the deviation behavior of the pre-coated metal coil 8 in advance according to the data of the edge offset distance fed back by the infrared sensor 1 and whether the long limit value alarms, and correct the track to ensure the continuous on-line operation and production of the pre-coated metal coil and avoid the occurrence of unsafe behaviors.

Of course, the above description is not a limitation to the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those of ordinary skill in the art within the essence of the present utility model should also fall within the protection scope of the present utility model.
