Description

Technical Field

[0001] The present invention relates to the technical field of mechanical engineering, and particularly to a dual-sensor high-efficiency paper feeding and rapid positioning structure. Background Art

[0002] In the traditional material processing field, especially in equipment involving paper feeding and cutting operations, position detection and positioning are crucial steps. Currently, it is relatively common to use a single sensor to perform this task. The single sensor faces many challenges in practical applications. In modern industrial production, the precision requirements for material processing are increasing day by day, especially in some high-end manufacturing industries, such as the manufacturing of precision electronic components and high-precision printing. However, a single sensor can often only provide accurate position information in one direction. For example, during the paper feeding process, if only the accurate position of the paper in the X direction can be determined, but there is a lack of precise positioning means in the Y direction, then when complex graphic cutting or high-precision typesetting and printing are required, it is difficult to ensure the processing precision. This is because many processing tasks require precise positioning of materials in multiple directions simultaneously, and the accurate position information in a single direction is far from sufficient to meet the overall precision requirements.

[0003] Moreover, the limitations of a single sensor are also very obvious. In a high-speed running processing scenario, it is difficult for a single sensor to ensure the accuracy of the material position every time the material starts and stops. Since the processing process is a continuous process, even a tiny position error will accumulate continuously during frequent start and stop operations. As the processing continues, this error accumulation will have a serious impact on the quality of the final product. Also, when multi-directional positioning is required, the single-sensor method often requires additional steps or manual intervention to complete. For example, after completing the X-direction positioning, manual adjustment or other auxiliary means are used to achieve the Y-direction positioning. This undoubtedly increases the processing time cost and reduces the overall production efficiency. In today's industrial environment that pursues high-efficiency production, this inefficiency caused by the positioning method is unacceptable.

[0004] In addition, on some highly automated production lines, the operating speed of the equipment is relatively fast, and the real-time requirements for position detection and positioning are also very high. Due to the limitations of its structure and function, a single sensor has deficiencies in rapid response and is difficult to meet the real-time positioning requirements under high-speed operation.

[0005] In order to overcome the above problems, a dual-sensor high-efficiency paper feeding and rapid positioning structure is proposed. Summary of the Invention

[0006] The main object of the present invention is to provide a dual-sensor high-efficiency paper feeding and rapid positioning structure, aiming to solve the technical problem that a single sensor can often only provide accurate position information in one direction, and for the precise positioning requirements in multiple directions, additional steps or manual intervention are required to complete, which not only increases the processing time but also reduces the overall production efficiency.

[0007] To achieve the above object of the invention, the present invention in a first aspect provides a dual-sensor high-efficiency paper feeding and rapid positioning structure, including a second color mark sensor and a deviation correction sensor, wherein the second color mark sensor is used to identify the color blocks on the material when the material moves along the paper feeding direction, and control the servo motor to achieve precise positioning in the X direction;

[0008] The deviation correction sensor is used to detect the offset of the material in the Y direction and output a signal for precise positioning in the Y direction.

[0009] Further, it further includes a first color mark sensor, which is used to perform preliminary position calibration on the tool holder under manual intervention when a new template enters the work.

[0010] Further, the second color mark sensor is fixedly installed above the material tape. During the movement of the material along the paper feeding direction, the second color mark sensor identifies the printed color blocks on the material and sends a signal to the control system. The control system controls the operation of the servo motor based on this signal, precisely controls the start and stop of the material, thereby achieving precise positioning of the material in the paper feeding direction.

[0011] Further, the deviation correction sensor is installed at the edge of the material tape, and the center of its recognition range is directly opposite to the edge of the material, serving as the zero position setting point;

[0012] When the material deviates in the Y direction due to tension change, the deviation correction sensor outputs the offset to the control system to achieve precise positioning in the Y direction.

[0013] Further, this structure can complete the processing process in three beats of tool lifting, rapid paper feeding, and tool lowering for processing, saving the repeated positioning time.

[0014] Further, when the tool holder lifts the tool after completing the cutting action of one layout, and after the material moves quickly and stops, the current position of the material is obtained through the second color mark sensor and the deviation correction sensor, avoiding repeated positioning actions.

[0015] Further, through the combined action of the second color mark sensor and the deviation correction sensor, rapid and precise positioning in both the X and Y directions is achieved, improving the overall processing efficiency.

[0016] Further, the control logic adopted by the control system can adjust the position of the material in real time according to the feedback information of the second color mark sensor and the deviation correction sensor to ensure the accuracy of each operation.

[0017] Further, the first color mark sensor, the deviation correction sensor, and the second color mark sensor are all electrically connected to the control system, and transmit the recognition information to the control system for corresponding control.

[0018] Further, the control system accurately controls the movement of the tool rest according to the signals of the second color mark sensor and the deviation correction sensor, so as to achieve high-tempo processing.

[0019] Beneficial effects:

[0020] The dual-sensor high-efficiency paper feeding and rapid positioning structure of the present invention derives beneficial effects based on the content of independent claim 1.

[0021] The present invention identifies the color blocks on the material through the second color mark sensor to achieve precise start-stop control along the paper feeding direction (X direction); at the same time, the deviation correction sensor can monitor and correct the deviation of the material in the direction perpendicular to the paper feeding direction (Y direction) in real time, ensuring the precise positioning of the material in both directions. Moreover, in this application, the tool rest is lifted after completing the cutting action of one layout, and the material can be quickly moved to the next position without repositioning, greatly reducing the time required for repeated positioning, improving the speed and efficiency of the entire processing process, and also achieving the rapid and precise positioning of the material in the X direction and Y direction, thereby significantly improving the processing efficiency and product quality.

[0022] By adjusting the mounting bracket to adapt to different types and sizes of materials, it has wide applicability and flexibility and can meet diverse production requirements. Description of the Drawings

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation of the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present invention, "a plurality" means two or more unless otherwise specifically defined.

[0030] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "connected" and "coupled" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection or an integral connection; it may be a mechanical connection, a direct connection or an indirect connection through an intermediate medium, and may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely means that the horizontal height of the first feature is lower than that of the second feature.

[0032] Referring to Figure 1 - Figure 2 , an embodiment of the present invention provides a dual-sensor high-efficiency paper feeding and rapid positioning structure, which includes a second color mark sensor 3 and a deviation correction sensor 2. The second color mark sensor 3 is used to identify the color block on the material when the material moves along the paper feeding direction, and control the servo motor to achieve precise positioning in the X direction;

[0033] The deviation correction sensor 2 is used to detect the offset of the material in the Y direction and output a signal for precise positioning in the Y direction.

[0034] In this embodiment, through the collaborative work of different sensors, rapid and precise position adjustment of the material in the X and Y directions is achieved.

[0035] It mainly includes a first color mark sensor 1, a deviation correction sensor 2, a second color mark sensor 3, a tool holder 4, and a control system. All sensors are electrically connected to the control system so as to transmit the recognized information to the control system in a timely manner, and then perform corresponding control operations.

[0036] The second color mark sensor 3 can be installed above the material tape at a position 20 - 50 mm through a bracket. The bracket is provided with a horizontal slide rail and a locking bolt, which can achieve a fine adjustment of the horizontal position of ±15 mm to ensure that the color block recognition area is strictly aligned with the material traveling trajectory. The deviation correction sensor 2 is preferably installed on the side of the material by means of an L-shaped cantilever.

[0037] During operation, the circuit system inside the second color mark sensor 3 detects and converts the optical signal entering its recognition area. It uses a specific optical filter that only allows the light wavelength matching the color characteristics of the color block to pass through, and then converts the optical signal into an electrical signal through a photodiode. This electrical signal is processed by amplification and filtering, and then sent to the internal analog-to-digital converter (ADC) to be converted into a digital signal for the control system to process.

[0038] When a new template is put into operation, the first color mark sensor 1 plays a role. At this time, under the condition of manual auxiliary intervention, the first color mark sensor 1 initially calibrates the position of the tool holder 4. Usually, the operator observes the feedback of the first color mark sensor 1 according to the characteristics of the template and the preset standards, and manually adjusts the position of the tool holder 4 to make the tool holder 4 in a relatively accurate starting processing position.

[0039] The second color mark sensor 3 precisely controls the position in the X direction during the paper feeding process of the material. The second color mark sensor 3 is fixedly installed directly above the material tape. When the material moves continuously along the paper feeding direction, the pre-printed color blocks on the material will enter the recognition area of the second color mark sensor 3. Once the second color mark sensor 3 recognizes these color blocks, it will quickly send out corresponding signals to the control system.

[0040] After receiving this signal, the control system issues a stop instruction to the running servo motor, so that the material stops precisely at the preset position, thus completing the precise positioning of the material in the paper feeding direction (that is, the X direction).

[0041] Optionally, it further includes a first color mark sensor 1, which is used to initially calibrate the position of the tool holder 4 under manual intervention when a new template enters operation.

[0042] It should be noted that the second color mark sensor 3 is fixedly installed above the material tape. When the material moves along the paper feeding direction, the second color mark sensor 3 identifies the color blocks printed on the material and sends a signal to the control system. The control system stops the servo motor to stop the material, thereby realizing the precise positioning control of the material in the paper feeding direction (X direction). The second color mark sensor 3 is fixedly installed above the material tape, can identify the color blocks printed on the material, and precisely control the start and stop of the material through the control system.

[0043] The deviation correction sensor 2 is installed at the edge of the material tape, and the center of its recognition range is directly opposite to the material edge, which is set as the zero position setting point.

[0044] When the material deviates in the Y direction due to tension changes, the deviation correction sensor 2 outputs the deviation amount to the control system to achieve precise positioning in the Y direction.

[0045] The function of the deviation correction sensor 2 is to complete the position positioning of the material in the Y direction. It is installed at the edge of the material tape, and the center of its recognition range is precisely aligned with the material edge, which is set as the zero position reference point.

[0046] The deviation correction sensor 2 internally adopts a laser emission and reception device. The laser emitter emits a narrow laser beam towards the material edge. When the laser beam irradiates the material edge, part of the light is reflected back and received by the receiver. The intensity and time information of the reflected light detected by the receiver are converted into an electrical signal, and this electrical signal reflects the position information of the material edge. By analyzing and processing this electrical signal, the deviation amount of the material in the Y direction can be obtained.

[0047] The control system is built-in with a dual-channel PID closed-loop control module. Among them, the X-direction control channel uses the pulse signal of the second color mark sensor 3 as the trigger source. When the front edge of the color block is detected, the position counter is started, and the real-time position deviation is calculated by combining the feedback value of the servo motor encoder, and the motor acceleration and deceleration curve is dynamically adjusted; the Y-direction control channel uses a fuzzy control algorithm to convert the 0-10V analog deviation signal output by the deviation correction sensor 2 into a phase angle compensation value of the deviation correction stepping motor, and the compensation response time ≤ 50ms. The data of the two channels are fused in the motion control card to generate a three-dimensional space deviation correction instruction.

[0048] The control system is built-in with a dual-channel PID closed-loop control module. Among them, the X-direction control channel uses the pulse signal of the second color mark sensor 3 as the trigger source. When the leading edge of the color block is detected, the position counter is started, and the real-time position deviation is calculated by combining the feedback value of the servo motor encoder, and the motor acceleration and deceleration curve is dynamically adjusted. Specifically, when the second color mark sensor 3 detects the leading edge of the color block, a pulse signal will be generated, and this signal is transmitted to the X-direction PID control channel of the control system. Inside the channel, first, the pulse signal is shaped and counted to obtain the position information of the current color block. At the same time, the servo motor encoder will real-time feedback the speed and position information of the motor. The X-direction PID control channel compares these two pieces of information and calculates the real-time position deviation. Then, according to the preset PID parameters (proportional, integral, and differential coefficients), the voltage adjustment amount that should be applied to the motor is calculated to adjust the motor acceleration and deceleration curve. For example, if the position deviation is large, the proportional coefficient will make the adjustment voltage large, causing the motor to decelerate quickly; if the deviation persists, the integral coefficient will continuously accumulate the deviation value and further adjust the voltage until the deviation is reduced to an acceptable range.

[0049] Among them, the calibration process is described in detail:

[0050] The initial calibration of the first color mark sensor 1 includes the following steps:

[0051] Manually place the standard calibration plate under the tool rest 4, and the plate is printed with a cross reference line and a color block array;

[0052] Activate the calibration mode through the HMI interface, and control the tool rest 4 to move along the X / Y axis until the first color mark sensor 1 detects the center of the reference color block;

[0053] The operator observes the deviation between the laser positioning mark and the calibration plate scale, and finely adjusts the mechanical zero point of the tool rest 4 through the handwheel;

[0054] After completing the X / Y two-way calibration, the system automatically records the compensation parameters and generates a calibration report.

[0055] Optimization of the material handling process:

[0056] In the high-speed paper feeding stage (speed ≥ 3m / s), the control system executes a prediction algorithm: based on historical positioning data, a material deformation model is established, and dynamic deceleration is started 300mm before the target position, specifically including:

[0057] When the second color mark sensor 3 detects the Nth color block, calculate the material elongation rate according to the spacing of the previous N - 1 color blocks, combine the real-time offset of the deviation correction sensor 2, and dynamically correct the final stop position coordinates

[0058] Switch to the fine positioning mode with a resolution of 0.1mm in the last 50mm stroke to ensure that the positioning error ≤ ±0.05mm.

[0059] When 3 consecutive color marks are not recognized, it automatically switches to the encoder mileage assisted positioning mode and triggers an audible and visual alarm at the same time; when the Y-direction offset exceeds the set threshold (default 2 mm), the roller reverse deviation correction program is urgently started, and the deviation correction force curve graph is displayed on the touch screen; it is equipped with a power-off memory module, and when there is an abnormal power-off, it can save key data such as the current coordinates and tension parameters to the FRAM memory.

[0060] The second color mark sensor 3 is preferably an RGB three-channel photoelectric sensor (such as the SICK CLV series), with a deviation correction sensor with a repeat positioning accuracy of 0.1 mm. The detection distance between the deviation correction sensor 2 and the edge of the material is 1.5 ± 0.2 mm, and the detection resolution reaches 0.02 mm; the servo motor is a 20-bit absolute encoder motor, which is combined with a harmonic reducer to achieve an angular positioning accuracy of 0.005°.

[0061] During the paper feeding process of the material, due to various factors (such as tension changes, etc.), the material may shift in the Y direction. Once this happens, the deviation correction sensor 2 will immediately detect the offset and output this offset information to the control system. The control system will then adjust the position of the material according to the received offset data to achieve precise positioning in the Y direction.

[0062] This structure can complete a high-efficiency processing process in the three-beat cycle of knife lifting, fast paper feeding, and knife lowering for processing, saving the repeated positioning time.

[0063] After the tool rest 4 completes the cutting action of one layout and lifts the knife, after the material moves quickly and stops, the current position of the material is obtained through the second color mark sensor 3 and the deviation correction sensor 2, avoiding repeated positioning actions.

[0064] This structure can complete efficient processing operations in the cycle formed by these three beats of knife lifting, fast paper feeding, and knife lowering for processing. The specific process is as follows:

[0065] After the tool rest 4 completes the cutting action of one layout, immediately perform the knife lifting operation; then the material moves at a relatively fast speed and stops after moving to the appropriate position. After the material stops, the second color mark sensor 3 and the deviation correction sensor 2 quickly start to work to obtain the position information of the current material in the X and Y directions. Because of the real-time and accurate feedback of these sensors, the processing process does not need to perform repeated positioning operations and can directly perform the processing of the next beat, greatly improving the overall processing efficiency.

[0066] Through the combined action of the second color mark sensor 3 and the deviation correction sensor 2, rapid and precise positioning in the X and Y directions is achieved, improving the overall processing efficiency.

[0067] The control logic adopted by the control system can adjust the position of the material in real time according to the feedback information of the second color mark sensor 3 and the deviation correction sensor 2, ensuring the accuracy of each operation.

[0068] The first color mark sensor 1, the deviation correction sensor 2, and the second color mark sensor 3 are all electrically connected to the control system, and transmit the recognition information to the control system for corresponding control. The control system accurately controls the movement of the tool rest 4 according to the signals of the second color mark sensor 3 and the deviation correction sensor 2, realizing high-beat processing.

[0069] The control logic adopted by the control system is the core element to ensure the efficient and accurate operation of the entire structure. It can dynamically and timely adjust the position of the material in the X and Y directions according to the real-time information fed back by the second color mark sensor 3 and the deviation correction sensor 2. Before each processing operation, the control system will accurately control the movement of the tool rest 4 according to the sensor feedback information, ensuring that each operation is accurate and error-free, thus realizing a high-beat and high-precision processing process.

[0070] Note: This double-sensor high-efficiency paper feeding and rapid positioning structure realizes the rapid and accurate position adjustment and efficient processing of the material in the X and Y directions through the collaborative work of multiple sensors and advanced control logic, and has significant application value and advantages.

[0071] When the tool rest 4 completes the cutting action of one layout, the tool lifting operation is immediately executed. The tool lifting operation is realized by the control system sending a specific instruction to the drive motor of the tool rest 4. This instruction will control the rotation direction and speed of the motor, so that the tool rest 4 is lifted upward at a stable speed. During the tool lifting process, the control system will monitor the position of the tool rest 4 in real time to ensure that the tool rest 4 can accurately reach the predetermined tool lifting height. For example, through the signals fed back by the limit switch or encoder installed on the tool rest 4, the control system can accurately control the tool lifting height of the tool rest 4, and the error range is controlled within ±0.1 mm.

[0072] The material moves at a relatively high speed. During this process, the rotation speed and torque of the paper feeding motor will be dynamically adjusted according to the characteristics of the material and the instructions of the control system. For example, for thicker materials or materials with greater surface friction, the paper feeding motor needs to provide a greater torque to ensure the smooth movement of the material. At the same time, in order to prevent the material from running off track during the rapid movement, the guiding devices on both sides of the equipment will adjust the position of the material in real time. The guiding devices detect the contact pressure between the material and the guiding devices through pressure sensors. When the pressure is uneven, the control system will adjust the spacing or pressure of the guiding devices to keep the material on the correct paper feeding path all the time. The speed control of the paper feeding motor is achieved through the feedback adjustment of the control system based on the preset paper feeding speed and the actually detected material movement speed. For example, if the actual paper feeding speed is lower than the preset speed, the control system will increase the input voltage of the paper feeding motor to increase the rotation speed of the motor until the actual speed reaches the preset speed.

[0073] Stop after moving to the appropriate position. This appropriate position is determined by the control system according to the processing task and the previous positioning information. When the control system determines that the material has reached the appropriate position, it will send a stop instruction to the paper feeding motor. After receiving the instruction, the paper feeding motor will gradually decelerate until it stops. During this process, in order to avoid sudden stop causing impact on the equipment, the control system will adopt soft stop technology, that is, gradually reduce the input voltage of the motor to make the motor stop smoothly. When the second color mark sensor 3 and the deviation correction sensor 2 quickly start to work to obtain the position information of the current material in the X and Y directions, the sensors will transmit the detected position information to the control system in the form of electrical signals. The control system will quickly process these signals. For example, the X-direction position information detected by the second color mark sensor 3 will be sent to the X-direction positioning module, and the Y-direction position information detected by the deviation correction sensor 2 will be sent to the Y-direction positioning module. The positioning module will evaluate the position of the material according to the preset positioning accuracy requirements (such as ±0.05 mm). If the position deviation is within the allowable range, it is considered that the positioning is successful; if it exceeds the range, the corresponding adjustment mechanism will be triggered.
