Description

Technical Field

[0001] This invention relates to the field of multi-layer cutting bed technology, and more specifically to a multi-layer cutting bed capable of inkjet printing. Background Technology

[0002] With the advancement of technology, automatic cutting tables have become increasingly common. These tables are automated cutting devices used in industries such as textiles, apparel, and leather, allowing for rapid fabric cutting. However, existing automatic cutting tables still rely on manual pre-marking during the cutting process. After the fabric is laid out, before cutting, the cutting path, internal hole positions, alignment points, and grain direction must be clearly marked on the fabric surface. Currently, this marking work relies almost entirely on manual operation (using chalk, chalk, markers, stickers, etc.). This is extremely time-consuming: For complex patterns or large fabric layers, manual marking and positioning takes a significant amount of time, becoming a bottleneck in the entire cutting process. It is also prone to errors: The accuracy of manual marking and positioning is affected by worker skill and fatigue, easily leading to deviations, resulting in cutting errors or misalignment. Furthermore, it lacks flexibility: Once the fabric is laid out, if modifications to the cutting plan or markings are needed, manual modifications are extremely difficult and may even require re-laying the fabric.

[0003] Its lack of inkjet printing capability is a key bottleneck restricting its efficiency and intelligence. This is not just a problem with "cutting" itself, but with the efficiency of the entire cutting preparation process. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-layer cutting bed that can be inkjet printed, thereby solving the following technical problem: the lack of inkjet printing function leads to low cutting efficiency.

[0005] The objective of this invention can be achieved through the following technical solutions: A multi-layer cutting bed capable of inkjet printing includes an operating platform and a movable frame that moves longitudinally therein, characterized in that the movable frame is provided with a multi-layer cutting bed assembly that moves laterally and vertically therein. The multi-layer cutting bed assembly includes a multi-layer cutting bed head and an inkjet mechanism. The inkjet mechanism includes an adapter mounting plate connected to the multi-layer cutting bed head. A fixing plate is provided on the adapter mounting plate, and an ink cartridge holder is slidably connected to the fixing plate. An ink head is installed inside the ink cartridge holder.

[0006] As a further aspect of the present invention: a fixing frame is fixedly installed on the fixing plate, and a driving mechanism is installed on the fixing frame. The driving mechanism is used to drive the ink cartridge holder and the ink head to move up and down.

[0007] As a further aspect of the present invention, the driving mechanism is a cylinder structure.

[0008] As a further aspect of the present invention, the driving mechanism is a motor lead screw structure.

[0009] As a further embodiment of the present invention: a guide rail is fixedly installed on the fixing plate, an ink cartridge holder is connected to the guide rail via a slider, and an ink cartridge holder and a photoelectric sensor are fixedly installed on the ink cartridge holder.

[0010] As a further aspect of the present invention, it also includes a control system for identifying the cutting path and controlling the drive mechanism to cut along the cutting path. Specifically, the control system includes: The standard acquisition unit is used to acquire the inkjet image and its location imported into the user's system, and to perform standard analysis. The vision unit is used to acquire inkjet images of the fabric to be cut placed on the cutting table, and to mark the real-time distances of the upper limit point, lower limit point, median point and the origin of the coordinate system corresponding to the acquired inkjet images as real-time upper limit distance, real-time lower limit distance and real-time median distance respectively; and to transmit the real-time upper limit distance, real-time lower limit distance and real-time median distance to the processing unit.

[0011] As a further aspect of the present invention: the standard analysis method is as follows: the standard inkjet image entered by the user and its positional relationship with the cutting bed are obtained, and the feature points of the inkjet image are selected to specify the origin of the point. Using the origin as the origin of the coordinate system, the horizontal and vertical movement directions of the clipping are marked as the X-axis and Y-axis, respectively. Then, the edge lines of the inkjet image are mapped onto the coordinate system, with the edge lines referring to the edges of the corresponding inkjet image. Obtain the position of the edge line in the coordinate system, and then select at least three points from the edge line. The distances of these three points from the origin are respectively the farthest, the closest, and the median point from the origin. Mark the farthest point as the upper limit point and the closest point as the lower limit point. The median point refers to the point whose distance from the origin is equal to the median of the distances from the upper limit point and the lower limit point to the origin. The distances between the corresponding upper limit point, lower limit point, median point and the origin of the coordinate system are marked as standard upper limit distance, standard lower limit distance and standard median distance; the standard upper limit distance, standard lower limit distance and standard median distance are transmitted to the processing unit.

[0012] As a further aspect of the present invention, the specific analysis method of the processing unit is as follows: Obtain the differences between the standard upper limit distance, standard lower limit distance, standard median distance and the corresponding real-time upper limit distance, real-time lower limit distance, and real-time median distance, and label them as upper limit difference, lower limit difference and median difference respectively; When any two of the upper limit difference, lower limit difference, and median difference exceed X1, it indicates that a medium wrinkle has occurred, and the staff will be automatically reminded to check the fabric to be cut. When any one of the upper limit difference, lower limit difference, and median difference exceeds X2, it indicates that an error wrinkle has occurred, and the staff will be automatically reminded to check the fabric to be cut.

[0013] The beneficial effects of this invention are: This invention enables inkjet printing by incorporating an inkjet mechanism on the head of a multi-layer cutting bed. The inkjet system, integrated into or above the cutting bed, automatically, quickly, and accurately prints the cutting outlines, internal hole positions, alignment crosshairs, fabric grain lines, piece numbers, production information, and other details from the CAD design directly onto the finished fabric surface. This saves time and labor: reducing manual work that previously took hours to minutes or even less significantly reduces labor costs and improves efficiency and quality. Furthermore, the control system enhances the overall automation level, allowing for automatic identification and adjustment based on the fabric type. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-4 As shown, the present invention is a multi-layer cutting bed that can be inkjet printed, including an operating platform 1 and a movable frame 2 that moves along its longitudinal direction. The movable frame 2 is provided with a multi-layer cutting bed assembly 3 that moves along its transverse and vertical directions. The multi-layer cutting bed assembly 3 includes a multi-layer cutting bed head 31 and an inkjet mechanism 32. The inkjet mechanism 32 includes a transition mounting plate 321 connected to the multi-layer cutting bed head 31. A fixing plate 322 is provided on the transition mounting plate 321. An ink cartridge holder 327 is slidably connected to the fixing plate 322. An ink head 328 is installed inside the ink cartridge holder 327.

[0018] A fixing frame 234 is fixedly installed on the fixing plate 322, and a driving mechanism 325 is installed on the fixing frame 234. The driving mechanism 325 is used to drive the ink cartridge holder 327 and the ink head 328 to move up and down.

[0019] The drive mechanism 325 is a cylinder structure. The drive mechanism 325 is also a motor lead screw structure. Both can drive the ink cartridge holder 327 to perform lifting and lowering movements; different drive methods are used depending on the requirements.

[0020] A guide rail 323 is fixedly installed on the fixed plate 322. A cartridge holder 326 is connected to the guide rail 323 via a slider. A cartridge holder 327 and a photoelectric sensor 329 are fixedly installed on the cartridge holder 326.

[0021] Its specific working process is as follows: The entire assembly is mounted on the head of the multi-layer cutting machine via an adapter plate; the ink cartridge holder 327 and the ink head 328 are driven up and down by the drive mechanism 325; the photoelectric sensor 329 senses the distance to the fabric and drives the drive mechanism 325 to stop rotating, and ink is sprayed. After ink spraying is completed, the drive mechanism 325 rises.

[0022] It also includes a control system, which identifies the cutting path and controls the drive mechanism to cut along the cutting path. The specific control system includes: The standard acquisition unit is used to acquire the inkjet image and its location imported into the user's system, and to perform standard analysis. Specifically, the method is as follows: The system obtains the standard inkjet image entered by the user and its positional relationship with the cutting bed. It then selects feature points from the inkjet image to specify the origin of the point. The specified point can be arbitrarily designated by the administrator. Using the origin as the origin of the coordinate system, the horizontal and vertical movement directions of the clipping are marked as the X-axis and Y-axis, respectively. Then, the edge lines of the inkjet image are mapped onto the coordinate system, with the edge lines referring to the edges of the corresponding inkjet image. Obtain the position of the edge line in the coordinate system, and then select at least three points from the edge line. The distances of these three points from the origin are respectively the farthest, the closest, and the median point from the origin. Mark the farthest point as the upper limit point and the closest point as the lower limit point. The median point refers to the point whose distance from the origin is equal to the median of the distances from the upper limit point and the lower limit point to the origin. The distances between the corresponding upper limit point, lower limit point, median point and the origin of the coordinate system are marked as standard upper limit distance, standard lower limit distance and standard median distance; the standard upper limit distance, standard lower limit distance and standard median distance are transmitted to the processing unit; The vision unit is used to acquire inkjet images of the fabric to be cut placed on the cutting table, and to mark the real-time distances of the upper limit point, lower limit point, and median point corresponding to the acquired inkjet images to the origin of the coordinate system as real-time upper limit distance, real-time lower limit distance, and real-time median distance, respectively. The real-time upper limit distance, real-time lower limit distance, and real-time median distance are transmitted to the processing unit. The processing unit is used for deviation analysis, and the specific analysis method is as follows: Obtain the differences between the standard upper limit distance, standard lower limit distance, standard median distance and the corresponding real-time upper limit distance, real-time lower limit distance, and real-time median distance, and label them as upper limit difference, lower limit difference and median difference respectively; When any two of the upper limit difference, lower limit difference, and median difference exceed X1, it indicates that a medium wrinkle has occurred, and the staff will be automatically reminded to check the fabric to be cut. When any of the upper limit difference, lower limit difference, and median difference exceeds X2, it indicates the presence of error wrinkles, and the system will automatically remind staff to inspect the fabric to be cut. Here, X1 and X2 are preset values, and the value of X1 is less than or equal to 0.75 times X2. Under normal circumstances, X1 can be set to 0.2 cm in actual operation, and X2 can be set to 0.3 cm. This setting can also be configured by the administrator according to the required precision for different materials. Of course, as another embodiment of this application, the deviation analysis method in this system is different, specifically: When a situation arises where staff need to inspect the fabric to be cut, as mentioned in the aforementioned embodiments, the staff to be cut are not notified first. Instead, based on the inkjet image imported into the system by the user and its location, several equidistant cutting points are made along its edge line, with the distance between each pair of cutting points being preset. Several split points are obtained, and then the distances of these split points from the origin in the standard coordinate system established under the imported system data are obtained. All distances are marked as standard distances. Then, the real-time distance between it and the origin is obtained with the help of the visual unit; The differences between several standard distances and real-time distances are obtained and marked as real-time differences; Points with a real-time difference exceeding X1 are marked as deviation points, and points that are marked as standard points are marked as such. Once the deviation point is obtained, the area where the wrinkle is located can be determined based on the deviation point, which is the angle between the deviation point and the origin.

[0023] The specific work process is as follows: 1. After creating the pattern from the garment design file drawn in PLT or professional garment CAD, use Super Nesting software to generate a CUT format cutting bed file with cutting paths and specified inkjet content; 2. Import the CUT format file into the Aorui multi-layer cutting machine output control system, and follow the working process of the control system described above; 3. Lay out the fabric, send it to the multi-layer cutting bed cutting area, and cover it with a film; 4. Adjust the machine and begin cutting; 5. Start the negative pressure pump, align with the origin, spray the number first, then cut.

[0024] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
