Description

Technical Field

[0001] The present invention relates to the field of heat transfer machine technology, and in particular to a heat transfer machine, a heat transfer method and an intelligent terminal. Background Art

[0002] The heat transfer machine can transfer various heat transfer patterns onto fabrics such as cotton, linen, and chemical fibers through heat transfer, and can also perform heat treatment processes such as screen printing, plastisol, and foaming. It can also bake color marks, portrait photos, landscape patterns, etc. on porcelain plates and metal plates, and is especially suitable for making medals, commemorative badges, cultural shirts, etc. It is economical and practical, and the patterns are exquisite. It is replacing traditional embroidery and screen printing, while the cost and effect are much lower and better than general embroidery and multi-color screen printing.

[0003] In the related art, a patent with the Chinese patent publication number CN107891660A discloses a heat transfer machine, which includes a chassis, a bracket arranged on the chassis, a heating plate, two linear slide rails, a workbench slidably connected to the two linear slide rails, and a cylinder arranged on the bracket; the end of the piston rod of the cylinder is detachably connected to the heating plate; the length of the workbench is not less than 2 times the length of the heating plate; a rack and pinion transmission mechanism and a driving motor are arranged on one side of the workbench. The heat transfer machine provided by the present invention realizes double-station alternate and cyclic work, that is, realizes continuous production and improves work efficiency.

[0004] In view of the above-mentioned related technology, since the materials of the clothing and the heat transfer are both manually placed on the work station, although there are marks on the clothing for the position of the heat transfer material to prevent deviation of the heat transfer material position, the position of the entire clothing is not fixed, and it is impossible to clearly identify whether the corresponding clothing is placed in place with the naked eye, which is likely to cause placement deviation, resulting in uneven heat transfer during the heat transfer process and even damaging the clothing. Summary of the Invention

[0005] In order to improve the situation that there are marks on the clothing, but the position of the entire clothing is not fixed, and it is impossible to clearly identify whether the corresponding clothing is placed in place with the naked eye, which is likely to cause placement deviation, the present invention provides a heat transfer machine, a heat transfer method and an intelligent terminal.

[0006] In the first aspect, the present invention provides a heat transfer machine, adopting the following technical solutions: A heat transfer machine, comprising: A workbench, on which a bracket is provided, and a slide rail is provided on the bracket along the length direction of the workbench; Station plates, arranged on the workbench, and the number of the station plates is two and they are arranged along the length direction of the workbench; The chassis is slidably connected to the slide rail. A first driving source for driving the chassis to slide is provided inside the chassis. The chassis extends to the workbench. A cylinder is provided inside the chassis. A heating plate is fixedly connected to the piston rod of the cylinder. The heating plate and the workbench cooperate to form a hot stamping space; and A positioning assembly, the positioning assembly includes: Passive rollers, rotatably connected to the periphery of the workbench; and Active rollers, rotatably connected to the periphery of the heating plate. Second driving sources for driving the active rollers to rotate are fixedly connected to the periphery of the heating plate. When the heating plate presses down onto the workbench, the active rollers and the passive rollers are in abutting cooperation to clamp the clothing, and when the active rollers and the passive rollers rotate, the clothing is moved.

[0007] By adopting the above technical solution, the position of the pattern is known by taking an image, then the offset position is determined according to the position of the pattern and the required position, and then the clothing is clamped and moved by the active rollers, so that the clothing is placed at the specified position, improving the accuracy of the clothing placement position.

[0008] In a second aspect, the present invention provides a hot stamping method, adopting the following technical solution: A hot stamping method, applied to a hot stamping machine as described above, includes: In response to a preset trigger signal, obtain a clothing placement image; Analyze the hot stamping pattern coordinates based on the clothing placement image and a preset hot stamping feature; When the hot stamping pattern coordinates are the preset standard pattern coordinates, control the heating plate to press down and start heating; When the hot stamping pattern coordinates are inconsistent with the standard pattern coordinates, determine the offset distance and offset direction based on the hot stamping pattern coordinates and the standard pattern coordinates; Based on the offset direction, find the corresponding corrected active roller number from a preset correction database; Determine the number of rotations of the active roller based on the offset distance; Control the heating plate to press down, and control the active roller with the corrected active roller number to rotate according to the number of rotations of the active roller, and then start heating.

[0009] By adopting the above technical solution, the position of the pattern is known by taking an image, then the offset position is determined according to the position of the pattern and the required position, and then the clothing is clamped and moved by the active rollers, so that the clothing is placed at the specified position, improving the accuracy of the clothing placement position.

[0010] Optionally, the method for determining the number of rotations of the active roller based on the offset distance includes: Control the heating plate to press down, then control the driving roller corresponding to the corrected driving roller number to rotate according to the preset number of unit turns, then control the heating plate to lift up and continue to obtain the clothing placement image and analyze the coordinates of the stamping pattern, and define the coordinates of the stamping pattern as the test pattern coordinates; Calculate the unit moving distance based on the test pattern coordinates and the stamping pattern coordinates; Calculate the number of turns of the driving roller based on the offset distance and the unit moving distance.

[0011] By adopting the above technical solution, since the thickness and material of each kind of clothing are different, the distance driven by one turn of the driving roller is also different, so the number of turns can be determined according to one turn of the driving roller, which improves the accuracy of the number of turns of the driving roller.

[0012] Optionally, before obtaining the clothing placement image, it further includes: Control the heating plate to press down and obtain the pressing signal fed back on the driving roller; Output the preset signal of no clothing placed when all the pressing signals are consistent with the preset no-load pressure signal; When all the pressing signals are inconsistent with the no-load pressure signal, lift up the heating plate, and then start the step of obtaining the clothing placement image; When there is a pressing signal consistent with the no-load pressure signal, obtain the no-load driving roller number corresponding to the pressing signal consistent with the no-load pressure signal; Find the corresponding symmetric driving roller number from the preset opposite-side database based on the no-load driving roller number; Output the preset signal of no clothing placed when the pressing signal corresponding to the symmetric driving roller number is also consistent with the no-load pressure signal; When the pressing signal corresponding to the symmetric driving roller number is inconsistent with the no-load pressure signal, determine the repair direction based on the symmetric driving roller number and the no-load driving roller number; Control the heating plate to rise by a preset micro-rising height, and then control the driving roller corresponding to the symmetric driving roller number to roll in the repair direction until the pressing signal corresponding to the no-load driving roller number is inconsistent with the no-load pressure signal.

[0013] By adopting the above technical solution, it is necessary to determine whether the placement is completed before obtaining the image. If the placement is completed but one driving roller does not clamp, the clothing can be pushed to the no-load driving roller by the opposite driving roller so that all the driving rollers can clamp, which is convenient for the operation process when adjusting the placement position of the clothing subsequently.

[0014] Optionally, after the step of controlling the heating plate to rise by a preset micro-rising height, and then controlling the driving roller corresponding to the symmetric driving roller number to roll in the repair direction until the pressing signal corresponding to the no-load driving roller number is inconsistent with the no-load pressure signal, it further includes: When the pressing signal corresponding to the idler driving roller number is inconsistent with the idler pressure signal, define the idler driving roller number as the reloaded driving roller number; Control the driving rollers corresponding to the reloaded driving roller number and the symmetric driving roller number to roll in the repair direction until the pressing signal corresponding to the reloaded driving roller number remains unchanged.

[0015] By adopting the above technical solution, when the clothing is pushed onto the idler driving roller, it can be assisted by the idler driving roller to improve the efficiency of clothing clamping.

[0016] Optionally, after controlling the driving rollers corresponding to the reloaded driving roller number and the symmetric driving roller number to roll in the repair direction until the pressing signal corresponding to the reloaded driving roller number remains unchanged, it further includes: Obtain the real-time pressure corresponding to the pressing signal, define the real-time pressure corresponding to the reloaded driving roller number as the real-time reloaded pressure, and define the real-time pressure corresponding to the symmetric driving roller number as the real-time symmetric pressure; Calculate the dynamic speed ratio based on the real-time reloaded pressure and the real-time symmetric pressure; Determine the dynamic rolling speed based on the dynamic speed ratio and the preset rated rolling speed; Determine the tensioning direction based on the repair direction; When the dynamic speed ratio is greater than 1, control the driving roller corresponding to the reloaded driving roller number to roll in the repair direction and at the rated rolling speed, control the driving roller corresponding to the symmetric driving roller number to roll in the tensioning direction and at the dynamic rolling speed, and continue to obtain the real-time reloaded pressure and the real-time symmetric pressure; When the dynamic speed ratio is less than 1, control the driving roller corresponding to the reloaded driving roller number to roll in the repair direction and at the dynamic rolling speed, control the driving roller corresponding to the symmetric driving roller number to roll in the tensioning direction and at the rated rolling speed, and continue to obtain the real-time reloaded pressure and the real-time symmetric pressure; When at least one of the real-time reloaded pressure and the real-time symmetric pressure is unstable, calculate the dynamic speed ratio and the dynamic rolling speed, and continue to roll; Stop rolling when both the real-time reloaded pressure and the real-time symmetric pressure are stable.

[0017] By adopting the above technical solution, when both are clamped, since the former is pushed over for clamping, it indicates that there may be wrinkles. Then, at this time, the two driving rollers need to roll in the reverse direction until balanced. When the pressure is balanced, it means that it has been spread out and straightened at this time. Then, the image can be obtained, ensuring the neatness of the clothing during the clothing ironing process.

[0018] Optionally, the method of controlling the heating plate to press down and then controlling the driving roller corresponding to the correction driving roller number to rotate according to the unit number of turns includes: Based on the corrected active roller number, find the corresponding symmetric active roller number from the opposite database, and define this symmetric active roller number as the symmetric corrected active roller number; When the corresponding real-time complex load pressure and real-time symmetric pressure are both stable, the active roller corresponding to the symmetric corrected active roller number does not roll, but controls the active roller corresponding to the corrected active roller number to rotate according to the unit number of turns; During the process of the active roller corresponding to the corrected active roller number rotating according to the unit number of turns, when the pressing signal and the no-load pressure signal corresponding to the symmetric corrected active roller number are consistent, re-control the heating plate to rise by the preset micro-rising height, and then control the active roller corresponding to the symmetric corrected active roller number to roll in the repair direction until the pressing signal and the no-load pressure signal corresponding to the no-load active roller number are inconsistent; During the process of the active roller corresponding to the corrected active roller number rotating according to the unit number of turns, when the pressing signal and the no-load pressure signal corresponding to the symmetric corrected active roller number are always inconsistent, control the heating plate to lift.

[0019] By adopting the above technical solution, one rotation also needs to be carried out when the clothing is flattened, and after one rotation, the four sides of the clothing are still clamped, so that it is ensured that the forward distance brought by one rotation in the whole process is fixed and will not be affected.

[0020] Optionally, the method of controlling the heating plate to press down and controlling the active roller with the corrected active roller number to rotate according to the number of turns of the active roller rotation and then starting to heat includes: During the process of controlling the active roller with the corrected active roller number to rotate according to the number of turns of the active roller rotation, obtain the pressing signals corresponding to the corrected active roller number and the symmetric corrected active roller number in real time, define the pressing signal corresponding to the corrected active roller number as the corrected pressing signal, and define the pressing signal corresponding to the symmetric corrected active roller number as the symmetric pressing signal; When the corrected pressing signal and the symmetric pressing signal are stable, continue to rotate until the number of turns of rotation reaches the number of turns of the active roller rotation; When the corrected pressing signal or the symmetric pressing signal changes, lift the heating plate to re-obtain the test pattern coordinates and recalculate the number of turns of the active roller rotation.

[0021] By adopting the above technical solution, the pressure needs to be kept stable during the rolling process. If the pressure changes, it is very likely that the forward distance value per turn changes. Therefore, it is necessary to re-determine the forward distance per turn to determine the subsequent forward distance required.

[0022] Optionally, it also includes the method of lifting the heating plate to re-obtain the test pattern coordinates and recalculate the number of turns of the active roller rotation when the corrected pressing signal or the symmetric pressing signal changes. This method includes: Obtain the total number of stable rolling circles when correcting the downward pressure signal or the change of the symmetric downward pressure signal; Continue to roll and obtain the total number of unstable rolling circles; Calculate the stable moving distance based on the total number of stable rolling circles and the unit moving distance; Calculate the maximum unstable moving distance based on the total number of unstable rolling circles and the preset maximum unit moving distance; Calculate the maximum moving distance based on the stable moving distance and the maximum unstable moving distance; When the maximum moving distance is less than the offset distance and the corrected downward pressure signal and the symmetric downward pressure signal remain stable, lift the heating plate to re-obtain the test pattern coordinates and re-calculate the number of rotations of the driving roller; When the maximum moving distance is less than the offset distance and the corrected downward pressure signal and the symmetric downward pressure signal still change, continue to roll; When the maximum moving distance is equal to the offset distance, lift the heating plate to re-obtain the test pattern coordinates and re-calculate the number of rotations of the driving roller.

[0023] By adopting the above technical solution, it is also possible to calculate according to the maximum distance per single time during the unstable process, and only lift the lifting plate to check the current situation when it is expected to reach the offset distance or reach the balance, reducing the energy required for frequent lifting and saving a large amount of resources.

[0024] In a third aspect, the present invention provides an intelligent terminal, adopting the following technical solution: An intelligent terminal includes a memory and a processor, and a computer program capable of being loaded and executed by the processor as any one of the methods described above is stored on the memory.

[0025] By adopting the above technical solution, the position of the pattern is known by taking a picture, then the offset position is determined according to the position of the pattern and the required position, and then the driving roller is used to clamp the clothing for movement, so that the clothing is placed at the specified position, improving the accuracy of the clothing placement position.

[0026] In summary, the present invention includes at least one of the following beneficial technical effects: Determine the offset position according to the position of the pattern and the required position, and then use the driving roller to clamp the clothing for movement, so that the clothing is placed at the specified position, improving the accuracy of the clothing placement position; Since the thickness and material of each piece of clothing are different, the distance driven by one rotation of the driving roller is also different, so the number of rotations can be determined according to one rotation of the driving roller, improving the accuracy of the number of rotations of the driving roller; Before acquiring the image, it is necessary to determine whether the placement is complete. If the placement is complete but one of the driving rollers is not clamping, the clothing can be pushed to the idle driving roller by the opposite driving roller so that all the driving rollers can clamp, which is convenient for the operation process during the subsequent adjustment of the clothing placement position.

[0037] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0038] An embodiment of the present invention discloses a hot stamping method. Refer to Figure 1 , a hot stamping method includes: Step 100: In response to a preset trigger signal, obtain a clothing placement image.

[0039] As Figure 2 shown, this hot stamping method is applied to a heat transfer machine, which includes a workbench 1, a station plate 2, a chassis 3, and a positioning assembly 4. A bracket 11 is installed on the workbench 1, and a slide rail 12 arranged along the length direction of the workbench 1 is installed on the bracket 11. The number of station plates 2 is two and they are arranged along the length direction of the workbench 1. Here, it can also be multiple to enable work on multiple stations. Generally, two are sufficient to continuously perform heat transfer work. The chassis 3 is slidably connected to the slide rail 12. A first driving source (not shown in the figure) for driving the chassis 3 to slide is installed in the chassis 3. The first driving source can be a motor, or if there are two stations, it can also be a cylinder drive. The chassis 3 extends to the station plate 2. A cylinder (not shown in the figure) is also installed in the chassis 3. The piston rod of the cylinder is arranged downward. A heating plate 31 is fixedly connected to the piston rod of the cylinder. The heating plate 31 extends above the station plate 2. The heating plate 31 and the station plate 2 cooperate to form a hot stamping space. The positioning assembly 4 includes a driving roller 41 and a driven roller 42. The driven roller 42 is rotatably connected to the periphery of the station plate 2. To prevent wrinkles, the highest point of the driven roller 42 can be flush with the upper surface of the station plate 2. The driving roller 41 is rotatably connected to the periphery of the heating plate 31. A second driving source (not shown in the figure) for driving the driving roller 41 to rotate is fixedly connected to the periphery of the heating plate 31. When the heating plate 31 presses down onto the station plate 2, the driving roller 41 and the driven roller 42 are in abutting cooperation to clamp the clothing and move the clothing when the driving roller 41 and the driven roller 42 rotate.

[0040] The trigger signal is a signal for triggering the heat transfer work. Here, buttons for triggering this trigger signal are provided at both stations. When one of them is triggered, the chassis 3 automatically moves to the corresponding position to perform heat transfer work. The clothing placement image is an image taken downward from the heating plate 31 when the clothing is placed on the station plate 2. It is obtained by a camera.

[0041] Step 101: Analyze the hot stamping pattern coordinates based on the clothing placement image and preset hot stamping features.

[0042] The hot stamping feature refers to the feature of the painting hot stamped on the garment. If it is a single color that is distinguishable from the color of the garment, it can be directly distinguished by the color feature. If not, it can be distinguished by one of the colors that is different from the color of the garment. The hot stamping pattern coordinates are the coordinates of the hot stamped pattern. Here, it can be the coordinates of a certain reference point. As long as it is determined, all subsequent points can be verified based on this point. For example: the leftmost point. The analysis method is the image contour analysis method.

[0043] Step 102: When the hot stamping pattern coordinates are the preset standard pattern coordinates, control the heating plate 31 to press down and start heating.

[0044] The standard pattern coordinates are the coordinate points of the hot stamping set artificially. When the hot stamping pattern coordinates are consistent with the standard pattern coordinates, it indicates that the garment is placed in place and the hot stamping is relatively uniform during the hot stamping process. Therefore, the hot stamping process can be normally executed at this time, and the heating plate 31 is controlled to press down and start heating.

[0045] Step 103: When the hot stamping pattern coordinates are inconsistent with the standard pattern coordinates, determine the offset distance and offset direction based on the hot stamping pattern coordinates and the standard pattern coordinates.

[0046] The offset distance is the distance from the hot stamping pattern coordinates to the standard pattern coordinates. Since the positioning component 4 of the entire device can only roll horizontally and vertically, the same is true for the garment. Therefore, the offset distance can be decomposed into two distances along the length direction and the width direction of the workbench 1. The offset direction is the moving direction from the hot stamping pattern coordinates to the standard pattern coordinates. Here, it can also be decomposed into two directions along the length direction and the width direction of the workbench 1. The determination method is to establish a coordinate system and draw a vector from the hot stamping pattern coordinates to the standard pattern coordinates, and then decompose it into two vectors along the length direction and the width direction of the workbench 1. The magnitudes of the two vectors are the offset distances, and the directions of the two vectors are the offset directions.

[0047] Step 104: Based on the offset direction, find the corresponding correction idler roller number from the preset correction database.

[0048] Correct the number of the driving roller to the number of the driving roller 41 for correcting the offset. The purpose of numbering is to determine which specific driving roller 41 it is. The mapping relationship between the offset direction and the number of the correcting driving roller is stored in the database. After the staff in the field numbers the driving roller 41, any one of the driving rollers 41 is selected to roll. If the driving roller 41 rolls inward, the clothing moving efficiency is not high. If the driving roller 41 rolls outward, the clothing can be dragged closer to the driving roller 41. Therefore, the driving roller 41 rolling outward is the main operation. At this time, record the number of the driving roller 41 and the moving direction of the clothing, define this moving direction as the offset direction, and then record the two to obtain the database. When the system receives the offset direction, it automatically looks up the corresponding number of the correcting driving roller in the database and outputs it.

[0049] Step 105: Determine the number of rotation circles of the driving roller based on the offset distance.

[0050] The number of rotation circles of the driving roller is the number of rotation circles that the driving roller 41 needs to rotate. Here, if the friction is large enough, for every distance the driving roller 41 rotates, the clothing moves the same distance. Generally, the number of rotation circles of the driving roller is obtained by dividing the offset distance by the circumference of the driving roller 41, or it can also be calculated by subsequent steps.

[0051] Step 106: Control the heating plate 31 to press down, and control the driving roller 41 with the number of the correcting driving roller to rotate according to the number of rotation circles of the driving roller, and then start heating.

[0052] Generally, in this case, the number of the correcting driving rollers is two, and the number of rotation circles of the driving roller can also be two.

[0053] Refer to Figure 3 , the method for determining the number of rotation circles of the driving roller based on the offset distance includes: Step 200: Control the heating plate 31 to press down, then control the driving roller 41 corresponding to the number of the correcting driving roller to rotate according to the preset unit number of rotation circles, then control the heating plate 31 to lift up and continue to obtain the clothing placement image and analyze the coordinates of the hot stamping pattern, and define these coordinates of the hot stamping pattern as the test pattern coordinates.

[0054] The unit number of rotation circles is one circle. The purpose of doing this here is to measure how much distance the clothing advances corresponding to the unit number of rotation circles. Since it is not certain to ensure static friction during the pressing process, it may be sliding friction. Therefore, there may be slippage between the driving roller 41 and the clothing. In this case, the clothing does not advance the same distance after the driving roller 41 rotates a certain distance. Therefore, testing is required.

[0055] Step 201: Calculate the unit moving distance based on the test pattern coordinates and the hot stamping pattern coordinates.

[0056] The unit moving distance is the distance moved in one circle of the unit. The calculation method here is to subtract the coordinates of the test pattern from the coordinates of the hot stamping pattern.

[0057] Step 202: Calculate the number of rotations of the driving roller based on the offset distance and the unit moving distance.

[0058] The calculation method is to divide the offset distance by the unit moving distance.

[0059] Here, the unit moving distance is the distance in two directions, and the offset distance is also the distance in two directions. Then, they can be divided one by one correspondingly.

[0060] Refer to Figure 4 , before obtaining the clothing placement image, it also includes: Step 300: After controlling the heating plate 31 to press down, obtain the pressing signal feedback on the driving roller 41.

[0061] The pressing signal is the signal of pressing down. Here, this signal can be the signal of the value corresponding to the contact pressure. The obtaining method can be obtained by a pressure sensor. Here, generally control the distance that the heating plate 31 moves downward. At this distance, there is only a little gap between the driving roller 41 and the driven roller 42. The size of this gap is thicker than the thickness of a single layer of clothing but thinner than the thickness of a double layer of clothing, so that when the clothing is placed, it will be squeezed against each other to generate a pressing signal. Here, the pressing down distance can be measured according to the specific clothing to be hot stamped.

[0062] Step 301: When all the pressing signals are consistent with the preset no-load pressure signal, output the preset no-clothing-placed signal.

[0063] The no-load pressure signal is the signal without contact to generate pressure, that is, the pressure of the sensor is 0. The no-clothing-placed signal is the signal without clothing placed. Here, the output method can be in the form of an alarm.

[0064] When all the pressing signals are consistent with the no-load pressure signal, it means that the clothing is not in place at all. At this time, it is impossible to correct according to the previous steps, nor can hot stamping be carried out. Then, directly output the signal that no clothing is placed.

[0065] Step 302: When all the pressing signals are inconsistent with the no-load pressure signal, lift the heating plate 31, and then start the step of obtaining the clothing placement image.

[0066] When all the pressing signals are inconsistent with the no-load pressure signal, it means that the clothing is all on the roller at this time, indicating that the placement is completed. Then, hot stamping is carried out in the normal way of steps 100 - 106.

[0067] Step 303: When there is a downward pressure signal that is consistent with the no-load pressure signal, obtain the no-load driving roller number corresponding to the downward pressure signal that is consistent with the no-load pressure signal.

[0068] The no-load driving roller number is the number of the driving roller 41 that does not hold the clothing. The obtaining method here can be a method of judgment, that is, when it is consistent with the no-load pressure signal, the no-load driving roller number is automatically output.

[0069] When there is a downward pressure signal that is consistent with the no-load pressure signal, it indicates that the clothing is not held by the roller at this position at this time. Therefore, it is necessary to know the number of the corresponding driving roller 41.

[0070] Step 304: Based on the no-load driving roller number, find the corresponding symmetric driving roller number from the preset opposite-side database.

[0071] The symmetric driving roller number is the number of the driving roller 41 corresponding to the no-load driving roller number. Here, it is the number of the driving roller 41 on the opposite side. The mapping relationship between the no-load driving roller number and the symmetric driving roller number is stored in the database. After all the driving rollers 41 are numbered by the staff in this field, the numbers of the two opposite-side driving rollers 41 are automatically associated and set. When the system receives the no-load driving roller number, the corresponding symmetric driving roller number is automatically found from the database and output.

[0072] Step 305: When the downward pressure signal corresponding to the symmetric driving roller number is also consistent with the no-load pressure signal, output the preset signal of no clothing placed.

[0073] When the downward pressure signal corresponding to the symmetric driving roller number is also consistent with the no-load pressure signal, it indicates that the symmetric driving roller 41 also does not hold the clothing, so the clothing cannot be moved by pushing.

[0074] Step 306: When the downward pressure signal corresponding to the symmetric driving roller number is not consistent with the no-load pressure signal, determine the repair direction based on the symmetric driving roller number and the no-load driving roller number.

[0075] The repair direction is the direction to move the clothing between the driving roller 41 corresponding to the no-load driving roller number and the corresponding driven roller 42. The determination method is from the side of the symmetric driving roller number to the side of the no-load driving roller number.

[0076] Step 307: Control the heating plate 31 to rise by a preset micro-rising height, and then control the driving roller 41 corresponding to the symmetric driving roller number to roll in the repair direction until the downward pressure signal corresponding to the no-load driving roller number is not consistent with the no-load pressure signal.

[0077] The slightly rising height is a height at which the garment can be moved by pushing. Due to the limitations of the heating plate 31 and the working plate 2 at the upper and lower positions, the garment can only move to one side.

[0078] Referring to Figure 5 , after the step of controlling the heating plate 31 to rise according to the preset slightly rising height and then controlling the driving roller 41 corresponding to the symmetric driving roller number to roll in the repair direction until the pressing signal corresponding to the no-load driving roller number and the no-load pressure signal are inconsistent, the following steps are further included: Step 400: When the pressing signal corresponding to the no-load driving roller number and the no-load pressure signal are inconsistent, define the no-load driving roller number as the reloaded driving roller number.

[0079] When the pressing signal corresponding to the no-load driving roller number and the no-load pressure signal are inconsistent, it indicates that the garment has moved between the driving roller 41 corresponding to the no-load driving roller number and the corresponding driven roller 42 at this time.

[0080] Step 401: Control the driving rollers 41 corresponding to the reloaded driving roller number and the symmetric driving roller number to roll in the repair direction until the pressing signal corresponding to the reloaded driving roller number remains unchanged.

[0081] Control the driving roller 41 corresponding to the reloaded driving roller number to actively roll to improve the efficiency of the driving roller 41 actively moving the garment.

[0082] Referring to Figure 6 , after controlling the driving rollers 41 corresponding to the reloaded driving roller number and the symmetric driving roller number to roll in the repair direction until the pressing signal corresponding to the reloaded driving roller number remains unchanged, the following steps are further included: Step 500: Obtain the real-time pressure corresponding to the pressing signal, define the real-time pressure corresponding to the reloaded driving roller number as the real-time reloaded pressure, and define the real-time pressure corresponding to the symmetric driving roller number as the real-time symmetric pressure.

[0083] The obtaining method is by using a pressure sensor.

[0084] Step 501: Calculate the dynamic speed ratio based on the real-time reloaded pressure and the real-time symmetric pressure.

[0085] The dynamic speed ratio is the ratio after converting pressure to speed. The calculation method is that the real-time reloaded pressure multiplied by the corresponding speed is equal to the real-time symmetric pressure multiplied by the corresponding speed, and then the dynamic speed ratio is obtained after conversion. Here, if the downward pressure of one end of the roller is too large, the rotation speed of the roller can be appropriately reduced, which can reduce the friction between the roller and the cloth.

[0086] Step 502: Determine the dynamic rolling speed based on the dynamic speed ratio and the preset rated rolling speed.

[0087] The rated rolling speed is the speed at which rolling can be achieved due to reasons of equipment such as motors. It is measured manually. The dynamic rolling speed is the rolling speed that needs to be changed to ensure the dynamic speed ratio. The calculation method is as follows: if the dynamic speed ratio is greater than 1, the dynamic rolling speed is the rated rolling speed divided by the dynamic speed ratio; if the dynamic speed ratio is less than 1, the dynamic rolling speed is the rated rolling speed multiplied by the dynamic speed ratio.

[0088] Step 503: Determine the tensioning direction based on the repair direction.

[0089] The tensioning direction is the direction opposite to the repair direction. The determination method is opposite to the repair direction.

[0090] Step 504: When the dynamic speed ratio is greater than 1, control the main roller 41 corresponding to the id number of the complex load main roller to roll in the repair direction and at the rated rolling speed, control the main roller 41 corresponding to the id number of the symmetric main roller to roll in the tensioning direction and at the dynamic rolling speed, and continue to obtain the real-time complex load pressure and the real-time symmetric pressure.

[0091] When the dynamic speed ratio is greater than 1, it indicates that the speed of the main roller 41 corresponding to the id number of the complex load main roller is relatively large, so this main roller 41 rolls at the rated rolling speed.

[0092] Step 505: When the dynamic speed ratio is less than 1, control the main roller 41 corresponding to the id number of the complex load main roller to roll in the repair direction and at the dynamic rolling speed, control the main roller 41 corresponding to the id number of the symmetric main roller to roll in the tensioning direction and at the rated rolling speed, and continue to obtain the real-time complex load pressure and the real-time symmetric pressure.

[0093] When the dynamic speed ratio is less than 1, it indicates that the speed of the main roller 41 corresponding to the id number of the complex load main roller is relatively small, so it just rolls at the dynamic rolling speed.

[0094] Step 506: When at least one of the real-time complex load pressure and the real-time symmetric pressure is unstable, calculate the dynamic speed ratio and the dynamic rolling speed, and continue to roll.

[0095] When at least one of the real-time complex load pressure and the real-time symmetric pressure is unstable, it indicates that there is still no internal tension at this time, so continue to move.

[0096] Step 507: Stop rolling when both the real-time complex load pressure and the real-time symmetric pressure are stable.

[0097] When both the real-time complex load pressure and the real-time symmetric pressure are stable, it indicates that the tensions at both ends are balanced, and at this time both ends are tensioned, so stop rolling.

[0098] Refer to Figure 7, the method of controlling the heating plate 31 to press down and then controlling the driving roller 41 corresponding to the corrected driving roller number to rotate according to the unit number of turns includes: Step 600: Based on the corrected driving roller number, find the corresponding symmetric driving roller number from the opposite database, and define this symmetric driving roller number as the symmetric corrected driving roller number.

[0099] The symmetric corrected driving roller number is the number of the driving roller 41 on the opposite side of the driving roller 41 corresponding to the corrected driving roller number. The establishment of the database was introduced in step 304 and will not be elaborated here. When the system receives the corrected driving roller number, it automatically finds the corresponding symmetric corrected driving roller number from the database and outputs it.

[0100] Step 601: When the corresponding real-time reloading pressure and real-time symmetric pressure are both stable, the driving roller 41 corresponding to the symmetric corrected driving roller number does not roll, and the driving roller 41 corresponding to the corrected driving roller number is controlled to rotate according to the unit number of turns.

[0101] When the real-time reloading pressure and real-time symmetric pressure are both stable, it means that it has been tightened and the measurement process is relatively stable. Then, at this time, the driving roller 41 corresponding to the corrected driving roller number is controlled to rotate according to the unit number of turns to ensure the accuracy of the measured distance advanced per single turn.

[0102] Step 602: During the process of the driving roller 41 corresponding to the corrected driving roller number rotating according to the unit number of turns, when the pressing signal corresponding to the symmetric corrected driving roller number is consistent with the no-load pressure signal, the heating plate 31 is controlled to rise again according to the preset micro-rising height, and then the driving roller 41 corresponding to the symmetric corrected driving roller number is controlled to roll in the repair direction until the pressing signal corresponding to the no-load driving roller number is inconsistent with the no-load pressure signal.

[0103] During the process of the driving roller 41 corresponding to the corrected driving roller number rotating according to the unit number of turns, when the pressing signal corresponding to the symmetric corrected driving roller number is consistent with the no-load pressure signal, it indicates that a detachment phenomenon has suddenly occurred, and then it can be adjusted in the manner of steps 500 - 507.

[0104] Step 603: During the process of the driving roller 41 corresponding to the corrected driving roller number rotating according to the unit number of turns, when the pressing signal corresponding to the symmetric corrected driving roller number is always inconsistent with the no-load pressure signal, the heating plate 31 is controlled to lift.

[0105] During the process of the driving roller 41 corresponding to the corrected driving roller number rotating according to the unit number of turns, when the pressing signal corresponding to the symmetric corrected driving roller number is always inconsistent with the no-load pressure signal, one turn of rotation also needs to be carried out with the clothing laid flat, and after one turn of rotation, the four sides of the clothing are still clamped, so as to ensure that the forward distance brought by one turn of rolling in the whole process is fixed and will not be affected. Reference Figure 8 , the method of controlling the heating plate 31 to press down and controlling the driving roller 41 for correcting the driving roller number to rotate according to the number of rotation circles of the driving roller, and then starting to heat includes: Step 700: During the process of controlling the driving roller 41 for correcting the driving roller number to rotate according to the number of rotation circles of the driving roller, obtain the pressing signals corresponding to the corrected driving roller number and the symmetrically corrected driving roller number in real time. Define the pressing signal corresponding to the corrected driving roller number as the corrected pressing signal, and define the pressing signal corresponding to the symmetrically corrected driving roller number as the symmetric pressing signal.

[0106] Step 701: Continue to rotate until the number of rotation circles reaches the number of rotation circles of the driving roller when the corrected pressing signal and the symmetric pressing signal are stable.

[0107] When the corrected pressing signal and the symmetric pressing signal are stable, it indicates that the driving roller 41 is rolling in a stable state at this time, so it can continue to roll.

[0108] Step 702: When the corrected pressing signal or the symmetric pressing signal changes, lift the heating plate 31 to re-obtain the test pattern coordinates and re-calculate the number of rotation circles of the driving roller.

[0109] When the corrected pressing signal or the symmetric pressing signal changes, it indicates that the pressure changes at this time. Then the sliding speed may change, so the previous distance per unit circle may be incorrect, and it needs to be re-calculated.

[0110] Reference Figure 9 , it also includes the method of lifting the heating plate 31 to re-obtain the test pattern coordinates and re-calculate the number of rotation circles of the driving roller when the corrected pressing signal or the symmetric pressing signal changes. This method includes: Step 800: Obtain the total stable rolling circles when the corrected pressing signal or the symmetric pressing signal changes.

[0111] The total stable rolling circles are the number of circles that have rolled before the corrected pressing signal or the symmetric pressing signal changes.

[0112] Step 801: Continue to roll and obtain the total unstable rolling circles.

[0113] The total unstable rolling circles are the number of circles that continue to roll after becoming unstable. The acquisition method is obtained by counting through a rolling counter.

[0114] Step 802: Calculate the stable moving distance based on the total stable rolling circles and the unit moving distance.

[0115] The stable moving distance is the distance that moves stably. The calculation method is the product of the two.

[0116] Step 803: Calculate the maximum unstable moving distance based on the total number of unstable rolling circles and the preset maximum unit moving distance.

[0117] The maximum unit moving distance is the moving distance of the largest single circle, which is measured by the staff in this field under different pressure modes. The maximum unstable moving distance is the distance when rolling according to the total number of unstable rolling circles at the maximum unit moving distance. The calculation method is the product of the two.

[0118] Step 804: Calculate the maximum moving distance based on the stable moving distance and the maximum unstable moving distance.

[0119] The maximum moving distance is the maximum distance in both stable and unstable cases. The most critical value is calculated here.

[0120] Step 805: When the maximum moving distance is less than the offset distance and the correction pressing signal and the symmetric pressing signal remain stable, lift the heating plate 31 to re-obtain the test pattern coordinates and re-calculate the number of rotations of the driving roller.

[0121] When the maximum moving distance is less than the offset distance, it means that the offset distance has definitely not been moved yet. However, at this time, the correction pressing signal and the symmetric pressing signal remain stable, indicating that it may be relatively stable subsequently. Then, the unit circle distance can be re-determined and the number of rotations of the driving roller can be calculated continuously.

[0122] Step 806: When the maximum moving distance is less than the offset distance and the correction pressing signal and the symmetric pressing signal still change, continue to roll.

[0123] When the maximum moving distance is less than the offset distance and the correction pressing signal and the symmetric pressing signal still change, it means that the offset distance has definitely not been moved yet. However, because the correction pressing signal and the symmetric pressing signal still change, it is very likely to be lifted and pressed repeatedly. Therefore, to avoid this situation, continue to roll while ensuring that the offset distance has not been completed.

[0124] Step 807: When the maximum moving distance is equal to the offset distance, lift the heating plate 31 to re-obtain the test pattern coordinates and re-calculate the number of rotations of the driving roller.

[0125] When the maximum moving distance is equal to the offset distance, it may reach the offset distance. Then, regardless of whether the correction pressing signal and the symmetric pressing signal are stable or change, it is necessary to lift it to detect whether the standard pattern coordinates are reached. If not, it is also necessary to continue to repeat obtaining the test pattern coordinates and calculating the number of rotations of the driving roller to avoid over-moving and exceeding the offset distance.
