Description

Technical Field

[0001] The present invention relates to the technical field of plate processing, and in particular to a plate coating deviation correction method, a deviation correction component and a plate processing device. Background Art

[0002] Lamination technology is widely used in furniture manufacturing, architectural decoration and other fields. Its main purpose is to improve the aesthetics and durability of the board. The traditional lamination process usually includes the following steps: Preparation: Select a suitable board as the substrate. Common substrates include medium-density fiberboard (MDF), particleboard, solid wood board, etc. At the same time, select appropriate film materials, such as PVC film, PET film, wood grain paper, etc. These films usually have various patterns and textures to meet different decoration needs. Cleaning: Thoroughly clean the surface of the board to remove dust, grease and other impurities to ensure that the surface is clean and smooth. Film coating: Apply glue on the surface of the film. Select the appropriate glue according to the material of the film. Commonly used glues include water-based glue, solvent-based glue, etc. The glue coating method can be manual glue coating or automatic glue coating equipment. The latter is suitable for large-scale continuous production. Heating: Heating can soften the film, making it easier to fit on the surface of the board and help the glue to bond better. Heating can be performed by infrared heaters, hot air guns, etc. Film application: Place the film on top of the board to ensure that the position is accurate. Use pressure equipment (such as rollers, presses) to tightly fit the film to the surface of the board, and remove the air between the film and the board to avoid bubbles. Cooling: Allow the laminated board to cool naturally to solidify the glue, or use equipment such as fans to accelerate the cooling process. Trimming and cleaning: Use special tools to remove excess film edges and remove residual glue and debris to ensure a clean surface of the finished product.

[0003] In the above-mentioned laminating process, the film is usually used in roll form. In order to ensure that the film can completely cover the plate, and considering the hysteresis of the film correction during the laminating process, a film with a width greater than the plate is usually used. Although this approach can solve the problem of position deviation during film lamination to a certain extent, it also brings a series of problems, mainly including: 1) Material waste: Since the width of the film is much larger than the actual width of the plate, a large amount of film material is cut off after lamination, resulting in material waste. At the same time, in order to ensure that the film can still be effectively bonded to the plate when it deviates, the glue coating area on the surface of the film needs to be larger than the area of ​​the plate to be laminated, which increases the amount of glue used and leads to glue waste. 2) Increased costs: Additional film materials and glue not only increase the cost of raw materials, but also consume additional manpower and energy in the subsequent cutting process, further increasing the overall production cost. 3) Environmental pollution: Wasted film materials and excess glue are difficult to degrade, increasing the pressure on the environment.

[0004] Therefore, how to reduce the material waste caused by film deviation in the lamination process is a problem that technical personnel in this field need to solve urgently. Summary of the invention

[0005] The invention provides a plate lamination deviation correction method, a deviation correction component and a plate processing device, which are used to solve the technical problem of material waste caused by film deviation in the plate lamination process in the prior art.

[0006] A first aspect of the present invention provides a plate lamination deviation correction method, comprising: S1: real-time acquisition of the offset A of the first position, the offset B of the second position and the offset C of the third position of the film, the first position is close to the unwinding section of the film, the second position is close to the gluing section of the film, and the third position is close to the laminating section of the film; S2: Calculate the real-time deviation x and real-time deviation speed S of the film according to A, B and C; S3: compare S with speed threshold S1; S4: If S ≥ S1, increase the glue coating width; S5: Control the plate to rotate nX / N along the offset direction, and control the film placing roller to move (N -n)A / N along the axial direction opposite to the offset direction, where N is an integer greater than or equal to 2, n≥Nn, and X is the offset degree when S5 is started; S6: Control the gluing component to move nB / N along the offset direction and reduce the gluing width.

[0007] In a first possible method for correcting deviation of a plate material during lamination according to the first aspect, S5 includes: S51: Compare X and the deviation threshold X1; S52: if X≤X1, the plate is controlled to rotate nX / N along the offset direction, and the film placing roller is controlled to move (N-n)A / N along the axial direction opposite to the offset direction, where N is an integer greater than or equal to 2, and n=Nn; S53: If X>X1, the plate is controlled to rotate nX / N along the offset direction, and the film placing roller is controlled to move (N-n)A / N along the axial direction opposite to the offset direction, n>Nn.

[0008] In a second possible method for correcting deviation of a plate material during lamination according to the first aspect, S4 includes: S41: If S>S1, increase the glue coating width; S42: If S≤S1, the film placing roller is controlled to move in the axial direction opposite to the offset direction.

[0009] In a third possible method for correcting deviation of a plate material during lamination according to the first aspect, S4 includes: If S>S1, the glue coating width is increased along the offset direction.

[0010] In a fourth possible method for correcting deviation of a plate material during lamination according to the first aspect, S6 includes: The gluing component is controlled to move nB / N in the offset direction and the gluing width is reduced.

[0011] In a fifth possible method for correcting deviation of plate lamination according to the first aspect, after S6, the method further includes: S7: Detect whether to start a new round of lamination; S8: If yes, compare X with the deviation threshold X1; S9: If X≤X1, the new sheet is controlled to flow in in the positive direction, and the film placing roller is controlled to move nA / N in the axial reverse offset direction, and the glue coating component is controlled to move (N -n)B / N in the reverse offset direction.

[0012] In a sixth possible method for correcting deviation of plate lamination according to the first aspect, after S6, the method further includes: S7: Detect whether to start a new round of lamination; S8: If yes, compare X with the deviation threshold X1; S9: If X>X1, the new sheet is controlled to flow in with a deflection (nm) X / N in the offset direction, and the film placing roller is controlled to move mA / N in the axial direction opposite to the offset direction, and the glue coating component is controlled to move mB / N in the opposite direction to the offset direction, where m is a positive number and n>m.

[0013] In combination with the sixth possible method for correcting the deviation of plate film coating of the first aspect, in a seventh possible method for correcting the deviation of plate film coating of the first aspect, after S9, the following steps are further included: S10: Execute S7 to S9 in a loop until 2(nm)X / N≤X1.

[0014] A second aspect of the present invention provides a deviation correction component, comprising: Any possible plate lamination deviation correction method provided in the first aspect is used for deviation correction.

[0015] A third aspect of the present invention provides a plate processing device, comprising: The second aspect provides a correction component.

[0016] It can be seen from the above technical solutions that the present invention has the following advantages: The plate coating correction method provided by the scheme obtains the offset A of the film in the unwinding section, the offset B in the gluing section and the offset C in the laminating section in real time, and then calculates the real-time offset x and the real-time offset speed S of the film according to the real-time offsets of the three positions, and then compares S and the offset speed S1. If S>S1, it means that the offset speed is faster. Before the film is corrected, the rapid offset of the film may cause the coating surface of the plate to run out of the area that can be covered by the gluing area of ​​the film. Therefore, the gluing width should be increased to increase the gluing area to ensure that the coating surface of the plate is fully covered. Then, the plate is controlled to rotate nX / N along the film offset direction, and the film unwinding roller is controlled to move (N-n)A / N along the axial direction opposite to the offset direction, that is, by adjusting the film and the plate at the same time, the relative offset of the film and the plate becomes zero, and finally the gluing component is controlled to move nB / N along the offset direction and reduce the gluing width. According to the deviation degree and deviation speed of the film, the position and gluing width of the plate, film placing roller and gluing assembly are adjusted to ensure that the coated surface of the plate can be fully covered by the gluing area of ​​the film, thereby reducing the redundancy of the film and the gluing area of ​​the film set up to deal with the deviation of the film, thereby reducing the amount of cut film and glue used, reducing material waste and lowering manufacturing costs.

[0017] At the same time, when the film is offset, the positions of the film placing roller and the plate are adjusted at the same time to eliminate the relative offset between the two. Compared with only adjusting the position of the film placing roller or the plate to eliminate the absolute offset between the two, the adjustment range is smaller, which can avoid film wrinkles caused by large adjustments and ensure that the film quality is not affected.

[0020] The embodiments of the present invention provide a plate lamination deviation correction method, a deviation correction component and a plate processing device, which are used to solve the technical problem of material waste caused by film deviation in the plate lamination process in the prior art.

[0021] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0024] In the existing laminating process, the film is usually used in roll form. In order to ensure that the film can completely cover the plate and take into account the hysteresis of the film during the lamination process, a film with a width greater than the plate is usually used. Although this approach can solve the problem of position deviation during film lamination to a certain extent, it also brings a series of problems, mainly including: 1) Material waste: Since the width of the film is much larger than the actual width of the plate, a large amount of film material is cut off after lamination, resulting in material waste. At the same time, in order to ensure that the film can still be effectively bonded to the plate when it deviates, the glue coating area on the surface of the film needs to be larger than the required lamination area of ​​the plate, which increases the amount of glue used and leads to glue waste. 2) Increased costs: Additional film materials and glue not only increase the cost of raw materials, but also consume additional manpower and energy in the subsequent cutting process, further increasing the overall production cost. 3) Environmental pollution: Wasted film materials and excess glue are difficult to degrade, increasing the pressure on the environment. Example

[0025] See also Figure 1 A plate lamination deviation correction method provided by an embodiment of the present invention includes: S1: real-time acquisition of the offset A of the first position, the offset B of the second position and the offset C of the third position of the film, the first position is close to the unwinding section of the film, the second position is close to the gluing section of the film, and the third position is close to the laminating section of the film; Specifically, a displacement sensor is provided near the film unwinding section, through which the offset A of the film at the first position is obtained in real time; a displacement sensor is provided near the film gluing section, through which the offset B of the film at the second position is obtained in real time; a displacement sensor is provided near the film laminating section, through which the offset C of the film at the third position is obtained in real time. In order to ensure the accuracy of the detection of the offset, a pair of displacement sensors can be provided at the first position, the second position and the third position, and each pair of displacement sensors is relatively provided at a position close to the edge of the film parallel to the flow direction, because when the film is offset, the edge of the film parallel to the flow direction moves to one side at the same time, so the displacement of the relative edges is detected simultaneously, which can improve the accuracy and reliability of the detection. It should be noted that the offset refers to the displacement of the edge of the film parallel to the flow direction (hereinafter referred to as the long edge) in the width direction compared to the position when it is not offset. The width of the film and the width of the glue coating on the film are set slightly larger than the width of the plate. The redundancy of the glue coating width is to provide enough time to adjust the position of the film roller, the glue coating assembly and the plate, and the glue coating width, so as to adjust the position of the plate before it runs out of the coverage of the film coating area. The redundancy of the film is to provide space for further increasing the glue coating width, so the specific value of the redundancy is set according to the position adjustment speed of the film roller, the rotation speed of the plate, the position adjustment speed of the glue coating assembly and the adjustment speed of the glue coating width. Before the offset occurs, the film width> glue coating width> plate width.

[0026] S2: Calculate the real-time deviation x and real-time deviation speed S of the film according to A, B and C; Specifically, the offset refers to the angle formed by the long edge of the film before and after the offset. Since the long edge of the film is presented as a curve, the offset can also be understood as the angle formed by the vertical plane where the long edge is located before and after the offset. Before the film is offset, the length from the laminating roller (used to press the film to the laminating surface of the plate) to the first position, the second position and the third position is known, so the specific offset can be calculated in combination with the corresponding offset. In this step, the offset is calculated in combination with the three real-time offsets to obtain three real-time offsets x. When A≥B≥C or A≤B≤C, the three calculated offsets are equal. The following is also based on the case of A≥B≥C. It should be noted that when B>C or B>A occurs, the offset of the film between the second position and the laminating roller is taken as x. The offset speed refers to the moving speed of the film in the width direction. Since the third position is closest to the plate, the offset speed of the third position has the greatest impact on the laminating quality, so the real-time offset of the third position is substituted into the speed calculation formula to calculate the real-time offset speed S.

[0027] S3: compare S with speed threshold S1; Specifically, the speed threshold S1 is a specific speed value, which is determined by the characteristics of the film. When the offset speed is less than this speed value, the film is controlled to move in the opposite direction of the offset (that is, the film roller is directly controlled to move), and the film will not form wrinkles under the two opposite forces of the correcting force and the offset force. Whether wrinkles are formed is affected not only by the characteristics of the film, but also by the width of the film. Therefore, the specific value of the speed threshold S1 needs to be tested and measured on a specific film.

[0028] S4: If S ≥ S1, increase the glue coating width; Specifically, when S≥S1, it means that the offset speed of the film is relatively fast at this time. If the position of the film placing roller is directly adjusted to correct the deviation at this time, it is equivalent to applying a correcting force opposite to the offset force to the film. Although the deviation correction can be achieved, the film is subject to the risk of forming wrinkles under the action of two opposite forces, which will affect the coating quality. In this step, in order to avoid this risk, the position of the film placing roller is not adjusted first, but the glue coating width is increased first, so as to obtain a larger glue coating width redundancy, thereby ensuring that the glue coating area of ​​the offset film can still completely cover the coating surface of the plate, that is, the glue coating area is increased to prevent the plate from running out of the coverable area of ​​the glue coating area.

[0029] S5: Control the plate to rotate nX / N along the offset direction, and control the film placing roller to move (N -n)A / N along the axial direction opposite to the offset direction, where N is an integer greater than or equal to 2, n≥Nn, and X is the offset degree when S5 is started; Specifically, the deflection of the film is a relatively short process, so after S4, the deflection speed of the film has dropped or has stopped deflecting, that is, S<S1. It should be noted that S4 and S5 are executed successively in the coating process of the same plate. Therefore, if only the film-releasing roller is controlled to move in the axial direction opposite to the deflection, due to the long length of the film between the film-releasing roller and the film-pressing roller, the large movement of the film may not only cause wrinkles in the film, but also have a certain correction hysteresis. If only the plate is controlled to rotate to adapt to the deflected film, so that the relative offset between the film and the plate becomes zero (that is, the long side of the coated surface of the plate is parallel to the long edge of the film), the plate may need to be rotated at a larger angle. Not only is it time-consuming to control the rotation of the plate longer, there is a certain correction hysteresis, and a larger space must be reserved for the rotation of the plate, which greatly increases the size of the equipment. In order to reduce the impact of the above shortcomings, in this step, the film-releasing roller is controlled to move in the axial direction opposite to the deflection (N -n)A / N, while controlling the plate to rotate nX / N in the offset direction, by adjusting the positions of the film roller and the plate at the same time, that is, controlling the film and the plate to move towards each other, so that the relative offset between the film and the plate becomes zero, both wrinkles and large-scale rotation of the plate can be avoided. Considering that a one-time large-scale movement of the film roller will have a greater impact on the lamination quality, it is preferred to set the plate position change to be larger than the film position change, that is, n≥Nn.

[0030] S6: Control the gluing component to move nB / N along the offset direction and reduce the gluing width.

[0031] Specifically, after step S5, the absolute offset of the plate and the film (i.e., the offset relative to the position when not offset) is still greater than zero, but the relative offset between the plate and the film is zero. At this time, the two are already in a relatively stable state, and the gluing width is increased in S4, so the redundancy of the gluing width is large at this time, and there is waste. Therefore, in order to reduce waste, in this step, the gluing component is controlled to move nB / N along the offset direction and reduce the gluing width.

[0032] The beneficial effects of this embodiment include: ① According to the deviation degree and deviation speed of the film, the position and gluing width of the plate, film placing roller and gluing assembly are adjusted, so as to ensure that the coated surface of the plate can be fully covered by the gluing area of ​​the film, and reduce the redundancy of the film and the gluing area of ​​the film set to deal with the deviation of the film, thereby reducing the amount of cut film and glue used, reducing material waste and reducing manufacturing costs.

[0033] ② When the film is offset, the positions of the film placing roller and the plate are adjusted at the same time to eliminate the relative offset between the two. Compared with only adjusting the position of the film placing roller or the plate to eliminate the absolute offset between the two, the adjustment range is smaller, which can avoid the film wrinkles caused by large adjustments and ensure that the film quality is not affected.

[0034] ③Reduce the redundant amount of film materials and glue required, and reduce pollution to the environment.

[0035] Optimization for S5: S51: Compare X and the deviation threshold X1; Specifically, the offset threshold is a specific offset. After the offset occurs, if the film roller is controlled to move significantly in the axial direction opposite to the offset direction for correction, the tension in a certain area of ​​the film will suddenly change, and the tension in the moving direction will become uneven, which may cause wrinkles. Therefore, the maximum movement of the film roller that the film can withstand is first determined (when the movement of the film roller is less than or equal to the maximum movement, wrinkles will not be formed, and when the movement of the grinding roller is greater than the maximum movement, wrinkles will be formed). Because the position change of the plate is greater than or equal to the position change of the film, the position change is measured by the offset variable caused by the position change, so the offset threshold X1 should be twice the offset corresponding to the maximum movement.

[0036] S52: if X≤X1, the plate is controlled to rotate nX / N along the offset direction, and the film placing roller is controlled to move (N-n)A / N along the axial direction opposite to the offset direction, where N is an integer greater than or equal to 2, and n=Nn; Specifically, since X1 is twice the offset corresponding to the maximum movement, and the position change of the plate is greater than or equal to the position change of the film, when X≤X1, it means that during the deviation correction process, the film placing roller only needs to move less than or equal to the "maximum movement" described in S51 to make the relative offset between the plate and the film become zero. More specifically, in this step, N=2, n=1, that is, the position change of the plate and the film is the same.

[0037] S53: If X>X1, the plate is controlled to rotate nX / N along the offset direction, and the film placing roller is controlled to move (N-n)A / N along the axial direction opposite to the offset direction, n>Nn.

[0038] Specifically, in order to avoid wrinkles, the displacement of the grinding roller must be less than or equal to the displacement W corresponding to X1 / 2. Therefore, when X>X1, (N-n)A / N≤W is required. Setting n>Nn can be understood as dividing the offset into N parts, where the plate rotates n parts along the offset direction, which is expressed as controlling the plate to rotate nX / N along the offset direction, and the film rotates (N-n) parts in the opposite offset direction, which is expressed as the film roller moving axially in the opposite offset direction (N-n)A / N. In this way, the long side of the coated surface of the plate is parallel to the long edge of the film, that is, the relative offset of the plate and the film is equal to zero, and the absolute offset is nX / N, thereby realizing relative deviation correction of the film.

[0039] Optimization of step S4: S41: If S>S1, increase the glue coating width; Specifically, when S>S1, it means that the offset speed is relatively fast. If the film roller is directly controlled to move for deviation correction, wrinkles may be generated in the film. Therefore, the glue coating area is increased by increasing the glue coating width to ensure that the glue coating area can fully cover the film coating surface of the plate, and the coating quality is not affected by the film offset. More specifically, when S>S1, the glue coating width is increased along the offset direction, that is, the glue coating width is increased to the side to which the film is offset. For example, if the film is offset to the right, the right end of the glue coating width of the glue coating component is controlled to move outward, and the increased glue coating width is equal to the offset of the film at the second position corresponding to the absolute offset nX / N.

[0040] S42: If S≤S1, the film placing roller is controlled to move in the axial direction opposite to the offset direction.

[0041] Specifically, when S≤S1, it means that the offset speed is slow at this time. Directly controlling the movement of the film roller for correction will not cause wrinkles in the film. Therefore, when X<X1 / 2, the film roller can be directly controlled to move in the axial direction opposite to the offset without rotating the plate, so that the absolute offset of the plate and the film becomes zero, thereby achieving absolute correction of the film. When X>X1 / 2, it is still necessary to simultaneously control the film and the plate to change position as described in step S52 to achieve relative correction.

[0042] Optimization of step S6: Control the glue coating assembly to move nB / N along the offset direction and reduce the glue coating width, and the reduced glue coating width is equal to the offset of the film at the second position corresponding to the absolute offset nX / N.

[0043] Further optimization of the plate lamination correction method. The above correction method only achieves relative correction, but not absolute correction. In order to achieve absolute correction, the following steps are added after S6: S7: Detect whether to start a new round of lamination; Specifically, the sensor detects whether there are plates to be coated that are ready to enter the coating station. If yes, it means that the plates being coated are almost finished and a new plate to be coated is ready to be coated.

[0044] S8: If yes, compare X with the deviation threshold X1; Specifically, when a new sheet material to be coated is to be coated, X is compared with the deviation threshold value X1, so as to control the position change of the new sheet material to be coated and the film placing roller according to the comparison result.

[0045] S9: If X≤X1, the new sheet is controlled to flow in in the positive direction, and the film placing roller is controlled to move nA / N in the axial reverse offset direction, and the glue coating component is controlled to move (N -n)B / N in the reverse offset direction.

[0046] Specifically, when X≤X1, after step S5, the film still has an absolute offset nX / N, and the movement of the film-releasing roller corresponding to the absolute offset nX / N is less than or equal to the "maximum movement", so the grinding roller is directly controlled to move nA / N in the opposite offset direction, and the glue coating component is controlled to move (N -n)B / N in the opposite offset direction, and then the new sheet material to be coated is controlled to flow in in the positive direction. In this way, the relative offset and absolute offset of the new sheet material to be coated and the film are both zero, achieving absolute correction.

[0047] The above step S9 is applicable to the case where X≤X1, and the following step S9 is applicable to the case where X>X1.

[0048] S9: If X>X1, the new sheet is controlled to flow in with a deflection (nm) X / N in the offset direction, and the film placing roller is controlled to move mA / N in the axial direction opposite to the offset direction, and the glue coating component is controlled to move mB / N in the opposite direction to the offset direction, where m is a positive number and n>m.

[0049] Specifically, when X>X1, after step S5, there is still an absolute offset nX / N, and the movement of the film-laying roller corresponding to the absolute offset nX / N is greater than the "maximum movement". Therefore, if the film-laying roller is directly controlled to move in the opposite direction of the offset, wrinkles will be generated in the film. Therefore, absolute deviation correction cannot be achieved by directly controlling the film-laying roller. It is still necessary to simultaneously control the change of the new sheet and the film-laying roller to reduce the absolute offset while keeping the relative offset at zero. Therefore, the new sheet is controlled to flow in with a deflection (nm) X / N in the offset direction, and the film-laying roller is controlled to move mA / N axially in the opposite direction of the offset. At the same time, the glue coating component is controlled to move m in the opposite direction of the offset. B / N can be understood as dividing the absolute offset nX / N into two parts: (nm)X / N and mX / N. Then, the new sheet is controlled to flow into the laminating station at an angle of (nm)X / N in the offset direction, and the film placing roller is controlled to move in the opposite direction of the offset by the offset amount corresponding to mX / N, that is, the sheet and the film are controlled to move toward each other, thereby reducing the absolute offset while keeping the relative offset at zero. After step S9, if there is still an absolute offset, in order to make the absolute offset zero, the following steps are added on the basis of S9: S10: Execute S7 to S9 in a loop until 2(nm)X / N≤X1.

[0050] Specifically, each time a new round of lamination begins, the film placing roller is controlled to move in the opposite direction of the offset, and the sheet is controlled to flow into the laminating station at a certain angle in the direction of the offset, so as to continuously reduce the absolute offset while ensuring that the relative offset is zero, until the offset corresponding to the absolute offset at the first position is less than or equal to the maximum movement. When this condition is met, S9 corresponding to X≤X1 is executed to make the absolute offset become zero, thereby achieving absolute correction. Example

[0051] A deviation correction component is provided in an embodiment of the present invention, and the deviation correction component adopts any one of the plate coating deviation correction methods provided in Example 1 for deviation correction. The deviation correction component integrates the function of obtaining the offset of the film in the unwinding section, the gluing section and the laminating section in real time, and can calculate the real-time offset degree and offset speed of the film based on these offsets. When the film deviates, the component can eliminate the relative offset between the film and the plate by adjusting the position of the plate, controlling the movement of the film unwinding roller and the position change of the gluing component. The advantage of this is that it reduces material waste, reduces costs, and helps to improve the quality of lamination. Example

[0052] A plate processing device is provided in an embodiment of the present invention, and the plate processing device uses the correction component provided in the second embodiment to correct the deviation.
