Description

Technical Field

[0001] This invention relates to the field of rotary die-cutting machine technology, and in particular to a method, apparatus, equipment and storage medium for checking the deviation of die-cutting rollers. Background Technology

[0002] The booming development of the post-printing market has led to a surge in demand for packaging boxes and signs made of various non-metallic materials, placing higher demands on processing equipment. Commonly used die-cutting machines on the market primarily employ planar and cylindrical die-cutting, but with the acceleration of intelligent manufacturing, rotary die-cutting is gradually taking a dominant position. Rotary die-cutting machines are rapidly developing due to their high speed, precision, and ease of adjustment. To adapt to a wider range of applications, the die-cutting rollers used for die-cutting have relatively large diameters, generally exceeding 150mm, and are magnetic for easy adsorption of the die-cutting mold. Such large-diameter magnetic rollers are generally quite heavy. The die-cutting roller is the most crucial component in a rotary die-cutting machine, playing a vital role in die-cutting accuracy. Therefore, ensuring proper installation and fit during operation is essential, making routine quality inspection quite challenging.

[0003] The existing technology CN106739485B discloses a method and device for online detection and fault diagnosis of longitudinal registration in printing presses. It uses color mark sensors to detect multiple color mark signals, and the generated pulse signals are filtered and then used for color signal identification. These signals are compared with high-speed, high-resolution pulse signals emitted by an encoder with high-precision displacement and speed detection to derive the initial registration error using a roller runout compensation algorithm. This method has some value. However, the use of multiple displacement sensors to capture multiple marker data, along with FPGA and host computer processing, makes the method very complex, involving many parameters and thus increasing the factors affecting accuracy. Furthermore, it lacks universality, only suitable for multi-color, multiple-repetition printing machines, which has significant limitations, is not very convenient to operate, and has low adoption rates.

[0004] Therefore, how to provide a solution to the above-mentioned technical problems is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0018] The encoder values ​​in the programmable logic controller are obtained each time the specific identifier is detected, and the encoder values ​​are converted using a preset conversion formula to obtain several encoder conversion values.

[0019] The maximum and minimum values ​​among the several encoder conversion values ​​are determined, and the deviation value of the target roller is determined based on the maximum and minimum values ​​using the range formula.

[0020] Optionally, the preset conversion formula is Jn = A MOD Sn (n>1); where Jn is the encoder conversion value, A is the circumference of the target roller, MOD is the modulo operation, and Sn is the encoder value in the programmable logic controller when the specific marker is detected for the nth time.

Obviously, the drawings described below are only embodiments of the present invention.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Because rotary die-cutting machines typically use large-diameter rollers, generally exceeding 150mm, and are solid magnetic structures, they are quite heavy. This makes precise installation and leveling difficult, and initial accuracy testing after installation is even more challenging. Currently, checking the deviation of the die-cutting rollers in rotary die-cutting machines can be done using a micrometer to measure the runout at each position and record the values. This method generally requires at least two people and is quite time-consuming. Alternatively, a separate specialized device using a grating ruler for scanning and inspection can be used, but this is also complex and inconvenient to operate.

[0043] Therefore, this application provides a die-cutting roller deviation inspection scheme, which can detect the deviation value of the die-cutting roller at the initial installation in a very simple way, so as to improve the machine yield rate; and the steps are simple, which can improve the accuracy detection efficiency of the die-cutting roller of the rotary die-cutting machine, ensure the cutting accuracy of the die-cutting machine, and has great applicability.

[0044] This invention discloses a method for checking the deviation of die-cutting rollers, see [link to relevant documentation]. Figure 1 As shown, applied to a rotary die-cutting machine, the method includes:

[0045] Step S11: Set a specific marker for the target roller on the rotary die-cutting machine in advance.

[0046] In this embodiment, a marker is set on the surface of the target roller, and then the deviation of the die-cutting roller is determined by detecting the position of the marker. Therefore, a specific marker is pre-set for the target roller on the rotary die-cutting machine, for example, a white rectangular marker is affixed for detection and identification. Figure 2 The diagram shows the setup. Actuator M1 is the target roller, including a servo driver and a servo motor; an identifier S is mounted on actuator M1; actuator M2 is a device for fixing sensor A. Figure 3 The diagram shows the setup of the marker. As you can see, detection can be achieved by setting up only one marker, making it simple to set up and easy to operate.

[0047] Step S12: When a precision detection task is detected, the pulse signal generated by the specific marker during each rotation of the target roller is detected by a preset color mark detection device.

[0048] In this embodiment, the preset color mark detection device is a sensor used to detect specific markers. The markers are detected and processed by adjusting the sensor's position and parameters. Specifically, the rotary die-cutting machine is started to make the target roller rotate at a uniform speed; when a precision detection task is detected, the sensor detects the pulse signal generated by the specific marker during each rotation of the target roller based on uniform speed.

[0049] In this embodiment, a preset color mark detection device detects specific markers arranged on the rollers of a rotary die-cutting machine, generating two pulse signals. One signal is transmitted to a servo driver, and the other to a programmable logic controller (PLC). The two signals are processed separately and then converged to the PLC, where an algorithm calculates a specific position value. Specifically, the pulse signal is divided into two paths to obtain a first pulse signal and a second pulse signal. The first pulse signal is transmitted to the servo driver, which uses a fast position capture mode to acquire the encoder value of the servo motor and transmits the encoder value to the PLC. The second pulse signal is transmitted to the PLC, which acquires the encoder value in real time via a hardware interrupt.

[0050] Normally, pulse signals are transmitted from a programmable logic controller (PLC) to a servo driver. In this embodiment, two pulse signals are generated. The first pulse signal is transmitted to the servo driver, which uses its own fast position capture mode to obtain the encoder value of the servo motor. Because servos have the advantages of high speed and high resolution, the values ​​acquired by the servo driver are reliable and stable. The servo encoder value is then transmitted to the controller.

[0051] The second pulse signal is transmitted to the programmable logic controller (PLC). Because the PLC is multi-axis, high-speed, and high-precision, its scan cycle can be set to 1ms, thus ensuring accurate calculation. Upon receiving the pulse signal from the sensor, the controller activates its internal function block and uses hardware interrupts to acquire the servo encoder value in real time, with a time error on the order of microseconds.

[0052] Step S13: Determine the deviation value of the target roller based on the pulse signal.

[0053] In this embodiment of the application, determining the deviation value of the target roller based on the pulse signal includes: acquiring the encoder values ​​in the programmable logic controller each time the specific marker is detected, and converting the encoder values ​​using a preset conversion formula to obtain a plurality of encoder conversion values; determining the maximum and minimum values ​​among the plurality of encoder conversion values, and determining the deviation value of the target roller based on the maximum and minimum values ​​using a range formula.

[0054] like Figure 4 As shown, when the device starts, it rotates at a constant speed v. During each rotation, the sensor detects the specific marker. The programmable logic controller (PLC) will acquire several encoder values ​​during the N rotations of the roller. Assuming the position of the first sampling pulse is S1, and considering the inherent errors in the installation and processing of the roller, the positions of each sampling pulse will not be exactly the same. The position of the second sampling pulse is recorded as S2, and so on, up to Sn. Further, a preset conversion formula is used to convert the encoder values ​​to obtain several encoder conversion values. The preset conversion formula is Jn = A MOD Sn (n>1); where Jn is the encoder conversion value, A is the circumference of the target roller, MOD is the modulo operation, and Sn is the encoder value in the PLC when the specific marker is detected for the nth time. Then, the range formula J = J max -J min The deviation value is derived; where J min J is the minimum value. max This is the maximum value. It should be noted that the programmable logic controller records preset parameters such as the roller diameter, and the value of the motor encoder obtained by sampling can be converted into the value of the circumference based on this parameter information.

[0055] Furthermore, in this embodiment, after determining the deviation value of the target roller based on the pulse signal, the method further includes: performing quality inspection on the rotary die-cutting machine based on the deviation value of the target roller. Once the deviation value of the die-cutting roller at initial installation is determined, the rotary die-cutting machine can be subjected to quality inspection to improve the machine's yield rate. Obtaining the most accurate deviation data with the fewest possible system components and parameters greatly improves the accuracy detection efficiency of the rotary die-cutting machine's die-cutting roller, ensuring the cutting accuracy of the die-cutting machine.

[0056] Furthermore, in this embodiment, after determining the deviation value of the target roller based on the pulse signal, the method further includes: recording the deviation value of the target roller in real time and displaying it on a touchscreen. It is evident that the values ​​obtained after the detection begins are recorded and displayed on the display device in real time, providing a more intuitive and easily observable feedback result. Because the detection results are intuitive, the detection of this type of equipment can be quantified and scaled up.

[0057] like Figure 5 The diagram illustrates an exemplary overall deviation inspection system, including the detection and processing of color mark pairs, sampling and processing by a servo drive system, data processing and display on a touchscreen, and deviation value sampling and calculation. For more detailed explanations of the working processes of each of these components, please refer to the corresponding content disclosed in the preceding steps; further elaboration is omitted here.

[0058] This application provides a method for checking the deviation of a die-cutting roller, applied to a rotary die-cutting machine.

This application, by pre-setting a specific marker on the target roller of the rotary die-cutting machine, only requires adjusting the position and parameters of the sensor to begin detection. The system configuration is simple and easy to operate; it detects the deviation value of the die-cutting roller at the initial installation stage in a very simple way, improving the machine yield rate and having great applicability.

[0059] Accordingly, this application also discloses a die-cutting roller deviation inspection device, see [link to relevant documentation]. Figure 6 As shown, the device includes:
