Description

FIELD

[0001] The present application relates to the technical field of cutting position detection for products to be cut, and specifically to a detection control system for the cutting position of a large-size sheet product.BACKGROUND

[0002] During the automatic cutting process of a large sheet of a valuable security, it is necessary to ensure the absolute accuracy of the product posture to guarantee the appearance and sizes of the cut products. In the initial cutting process, there is not any detection mechanism. When the product reaches a cutting position, a side gauge will tap and arrange it to position the product, and after the positioning is completed, a cutting knife starts to cut the product. This method has a significant potential risk, i.e., when the product posture deviates greatly, the tapping of the side gauge cannot achieve effective correction, resulting in defective product during cutting.

[0003] With the upgrading of detection technologies, after the side gauge completes tapping, four cameras mounted directly above the product verify the posture of the product surface. If a verification result is within an error range, the cutting operation can be started. However, this detection method has a defect, i.e., when the product surface is misaligned with the product below, the quality of the product below cannot be effectively guaranteed after cutting.

[0004] During the large-sheet cutting process, since the printed products are not produced by the same printing machine, each stack of products has a different positioning reference. Therefore, during the cutting process, it is necessary to check whether the cutting line of each stack coincides with an actual cutting position. When the deviation is too large, the machine needs to be stopped, and it needs two persons to cooperate to adjust the side gauge. As the reference edge is on a non-operating side and the cutting positions on the two sides both need to be taken into account, two persons are needed for collaborative operation. In the process of adjusting the side gauge, the two operators need to communicate to adjust the sizes of the side gauge. However, each person has a different understanding of the size of the reference edge, so there may be information asymmetry during the communication, leading to errors in the adjusted sizes.SUMMARY

[0005] The present application aims to solve at least one of the above technical problems.

[0006] Thus, a first purpose of the present application is to propose a detection control system for a cutting position of a large-size sheet product.

[0007] To achieve the first purpose of the present application, the technical solutions of the present application provide a detection control system for a cutting position of a large-size sheet product, comprising: horizontal pan / tilt heads; an image acquisition module comprising industrial cameras, light sources and supports, wherein the supports are disposed on the horizontal pan / tilt heads, both the industrial cameras and the light sources are movably connected to the supports, and the supports comprise arc-shaped supports; a side gauge driving module, provided on one side of the horizontal pan / tilt heads, and comprising a side gauge, a stepper motor and a position sensor, wherein the stepper motor is connected to the side gauge and configured to adjust the side gauge, and the position sensor is connected to the stepper motor and configured to feed back the size of the side gauge adjusted by the stepper motor; and an information processing module, connected to the image acquisition module and the side gauge driving module respectively, and configured to acquire an image acquired by the image acquisition module, obtaining a deviation value between a cutting line of the image and a template on the basis of the image, and controlling, on the basis of the deviation value, the stepper motor to adjust the side gauge.

[0008] In the technical solution, the detection control system for a cutting position of a large-size sheet product comprises the horizontal pan / tilt heads, the image acquisition module, the side gauge driving module, and the information processing module. Wherein, the image acquisition module comprises the industrial cameras, the light sources, and the supports. The supports are mounted on the horizontal pan / tilt heads, which can expand the shooting range, cover all types of large products that need to be shot, and ensure a best shooting position. Both the industrial cameras and the light sources are movably connected to the arc-shaped supports to adjust the shooting angles of the cameras. When the positions of the industrial cameras are adjusted, it is unnecessary to adjust the focal lengths of the industrial cameras, and thus adjustment time is saved. The side gauge driving module comprises the side gauge, the stepper motor, and the position sensor. The stepper motor is configured to adjust the side gauge, and after the stepper motor completes adjustment, a high-precision position sensor mounted on one side feeds back the adjusted size of the side gauge by the stepper motor, realizing closed-loop control in program. Adopting the stepper motor to drive the adjustment of the size of the side gauge enables real-time automatic adjustment of the size of the side gauge. After the image acquisition module completes an image acquisition task, the information processing module acquires the image collected by the image acquisition module, compares a cutting line on the image with the template to obtain the deviation value between the cutting line of the image and the template, and controls the stepper motor to adjust the corresponding parameters of the side gauge according to the deviation value. After the adjustment is completed, comparison with the change value of the position sensor is performed to ensure the accuracy of the motor in parameter adjustment. The adjustment precision of the stepper motor can reach 0.02mm, which greatly improves the adjustment precision for the side gauge. The technical solution of the present application can more accurately and directly measure the deviation size of the side gauge, and improve the cutting quality of products. By using the arc-shaped supports, it is unnecessary to adjust the focal lengths when the positions of the industrial cameras are adjusted, and data use requirements are met. When the stepper motor is adopted to drive the parameter adjustment of the side gauge and adjust the size of the side gauge, manual intervention or fully automatic adjustment can be adopted, which is simple and fast, and can reduce the use of labor, greatly improve work efficiency, and shorten the shut downtime in adjusting the side gauge.

[0038] In the above embodiment, optionally, the arc-shaped support 130 is a 45° arc-shaped support with the cutting edge of the cutting knife as the circle center and the distance from the cutting knife to the center line of the horizontal pan / tilt heads 110 as the radius.

[0042] In the above embodiment, optionally, the light sources comprise first light sources and second light sources. The first light sources are connected to the front end cutting line cameras, and the second light sources are connected to the rear end cutting line cameras.

[0043] In the above embodiment, optionally, the information processing module comprises a computer. The computer is connected to the industrial cameras 120, and is configured to acquire the images collected by the industrial cameras 120 and calculate the deviation value between the cutting lines of the images and the template based on the images. The information processing module further comprises the PLC, which is respectively connected to the computer and the stepper motor 140, and is configured to control the stepper motor 140 to adjust the corresponding parameters of the side gauge according to the deviation value. The PLC is further connected to the alarm device, and is configured to control the alarm device to sound an alarm when the deviation value exceeds a preset value.

[0044] In the above embodiment, optionally, the alarm device can be an alarm light.

[0045] As shown in FIG. 1, FIG. 2, FIG. 3 and FIG. 4, the detection control system 10 for a cutting position of a large-size sheet product according to a specific embodiment of the present application solves the problem of measuring the product position, sheet feeding and separating status, and skew size of valuable securities during the large-sheet cutting process, collecting number information, and providing alarms and deviation values when abnormalities occur. The system is composed of advanced technologies such as industrial cameras 120, a PLC control technology, and a driving technology of the stepper motor 140.

[0046] In an existing early warning system for the large-sheet cutting process, two cameras are mounted between a set of knife boxes at the trimming station to collect two marker points when the product is located at a centered position, so as to determine the position deviation of the product. During the printing process, different pressures of the printing machine lead to sheet stretching or shrinking of the product. When the pressure of the printing machine is too high, the product will be compressed and deformed, resulting in the expansion of the product width. At the moment, the verification deviation of the four detection points near the middle is within a deviation range, but the cutting precision requirements of the cutting lines near the product edges cannot be guaranteed. Therefore, our technology uses two industrial cameras 120 to collect the positions of the cutting lines at the edges of a large-sheet product and determine whether the first product sheet is misaligned. Only two cameras are reserved in the middle of the product, wherein one camera collects the crown characters of the product, and the other collects the deviation of the markers. At this moment, several cameras align one cutting surface to prevent product skewing.

[0047] The image acquisition module consists of industrial cameras 120, light sources and supports. In terms of structure, the image acquisition module needs to collect the front and rear cutting lines of a large-sheet product. However, considering compatibility with all product types and the position differences in cutting lines, to ensure the best shooting position, the supports are mounted on the horizontal pan / tilt heads 110 to expand the shooting range. To adjust the shooting angles of the cameras, a 45° arc-shaped support is designed with the cutting edge of the cutting knife as the circle center and the distance from the cutting knife to the center line of the pan / tilt heads as the radius. When the camera positions are adjusted, it is unnecessary to adjust the focal lengths of the cameras, and thus the adjustment time is saved.

[0048] When the size of the side gauge is adjusted, the original adjustment method requires an operator to rotate an adjustment handle on an operating side, and a dial indicator is fixed above the rotating handle to monitor the adjustment value of the side gauge in real time. We have improved the adjustment method of the side gauge by upgrading the rotating handle for adjusting the side gauge to be a stepper motor for driving. After the adjustment by the stepper motor 140 is completed, a high-precision position sensor mounted on one side feeds back the size of the side gauge adjusted by the stepper motor 140, achieving a closed-loop control in program.

[0049] Adopting a stepper motor to drive the adjustment of the size of the side gauge can achieve an automatic adjustment of the size of the side gauge in real-time. After the image acquisition module completes the image collection task, it compares the cutting lines of the image with the template and transmits the deviation value to the computer, and the computer sends the deviation value to the PLC to control the stepper motor 140 to adjust the corresponding parameters of the side gauge. After the adjustment is completed, comparison with the change value of the position sensor is performed to ensure the accuracy of the motor in parameter adjustment. The adjustment precision of the stepper motor 140 can reach 0.02 mm, and the adjustment precision of the side gauge is greatly improved.

[0050] Meanwhile, the system allows manual intervention in adjusting the size of the side gauge. After the collected data are transmitted to the computer , the computer presents the deviation parameters to the operator as a recommended value. The operator, through the collected images and the actual positions of the product on the operating side, adds subjective manual judgment and completes the adjustment of the size of the side gauge.

[0051] Compared with the previous operation method, both the automatic adjustment and manual intervention adjustment for the size of the side gauge can reduce manual labor, significantly improve working efficiency, and shorten the shut downtime for the adjustment of the side gauge.

[0052] The embodiment can more accurately and directly measure the deviation size of the side gauge, and then improve the cutting quality of products. When collecting the edges of large-sheet products, due to position constraints, the cameras cannot vertically collect the cutting lines. An innovative arc-shaped support is adopted, and then it is unnecessary to adjust the focal lengths when the camera positions are adjusted, and meanwhile, the data use requirement is met. In the process of side gauge adjustment, the stepper motor is innovatively applied for driving the parameter adjustment of the side gauge. Either a manual intervention method or a fully automatic method can be adopted during the adjustment of the size of the side gauge, which is simple and efficient. The application of the early warning system for process control eliminates the occurrence of previously scrapping an entire product with one wrong cut, ensures the cutting quality of products, reduces manual involvement, and lowers the labor intensity of employees at the same time.
