Description

Technical Field

[0001] This invention relates to the field of cutting bed technology, and more specifically to a cutting bed sorting system and a cutting bed. Background Technology

[0002] When cutting pieces are collected after the automatic cutting machine finishes cutting, the remaining fabric scraps are not recycled. However, in a cutting machine with a continuous feed system, the fabric is constantly fed to the cutting table, so the scraps become longer and longer, requiring timely recycling. Currently, the common method is to collect a portion of the cut pieces, cut the corresponding scraps, and then recycle them. See patent publication number CN108823942A, but its cutting lines are set as multiple unconnected straight lines, and the cutting lines generated each time are different, making the operation more complicated.

[0003] Therefore, optimizing the automatic collection of cut pieces and the recycling of leftover materials are problems that need to be solved. Summary of the Invention

[0004] The purpose of this invention is to provide a cutting bed sorting system and a cutting bed that can realize the automatic sorting of cut pieces and the recycling of leftover materials, simplifying the cutting process of leftover materials.

[0005] To achieve the above objectives, the present invention provides a cutting bed sorting system, wherein the cutting surface of the cutting bed is sequentially divided into a cutting area and a sorting area according to the fabric's transport direction from inlet to outlet, and the cutting bed sorting system includes:

[0006] The sorting module is used to sort the cut pieces on the sorting area;

[0007] A cutting module is used to cut off excess material along a fixed cutting path, which is a straight line; the cutting path is the boundary line between the cutting area and the picking area, or the cutting path is located in the picking area;

[0008] The control module is used to control the operation of the picking module and the cutting module;

[0009] While the sorting module is sorting the cut pieces, the cutting area is simultaneously performing the cutting operation.

[0010] In an optional embodiment, the sorting module includes multiple sorting units;

[0011] The sorting module has two working modes: single sorting mode and double sorting mode.

[0012] In the single-pickup mode, all the picking units pick up the cut pieces in the first manner;

[0013] In the dual-sorting mode, the sorting unit is divided into two groups. The first group is used to sort the cut pieces that intersect with the cutting path in a second manner, and the second group is used to sort the remaining cut pieces in a first manner.

[0014] In the alternative solutions, the first method involves two sorting units cooperating to sort two pieces of fabric, while the second method involves each sorting unit sorting one piece of fabric independently.

[0015] In an optional configuration, the control module is further configured to determine whether there are cut pieces on the cutting path of the cutting module; if cut pieces are determined to be present, the picking module operates in the double picking mode; otherwise, it operates in the single picking mode.

[0016] In an alternative embodiment, the first group of picking units consists of a predetermined number of units, all of which are located close to the cutting path.

[0017] In an optional embodiment, the method for determining whether there is a cut piece on the cutting path of the cutting module includes:

[0018] Determine the number of intersection points between the cutting path and the outer contour curve of the cut piece. If the number is greater than 0, then there is a cut piece on the cutting path.

[0019] In an optional embodiment, the picking unit includes a telescopic rotating rod, a telescopic rod, and a suction cup;

[0020] The telescopic rotating rod can slide along the track, extend and retract in the longitudinal direction, and rotate about itself as an axis of rotation;

[0021] The telescopic rod is connected to the lower end of the telescopic rotating rod, and the telescopic rod can extend and retract in the horizontal direction;

[0022] The suction cup is rotatably connected to the end of the telescopic rod;

[0023] The control module controls the movement of the telescopic rotating rod, the telescopic rod, and the suction cup to make the suction cup reach the preset piece adsorption position.

[0024] In an optional configuration, the suction cup is equipped with a displacement sensor to collect its position coordinates, thereby matching the position of the suction cup with a preset fabric piece adsorption position via the control module.

[0025] In an optional embodiment, the telescopic rod has two ends, each end of which is connected to a suction cup, and the two suction cups work independently.

[0026] The present invention also provides a cutting bed, including the above-described cutting bed sorting system.

[0027] The beneficial effects of this invention are as follows:

[0028] This invention enables automatic sorting of cut pieces and recycling of leftover materials. The cutting position and shape of the leftover materials are always a fixed straight line, which simplifies the cutting process of leftover materials.

[0029] Furthermore, by having two sorting units work together to sort two pieces of fabric, the average volume of each sorting unit can be significantly reduced, increasing the maximum number of sorting units that can be accommodated simultaneously in the upper space of the cutting bed.

[0030] Furthermore, the dual-picking mode (second method) can improve response speed and execution speed. The switching judgment between the two modes is simple (only to determine whether n is greater than 0, where n is the number of intersections between the cutting path and the outer contour curve of the cut piece), providing a higher degree of freedom for process optimization.

[0042] Example 1

[0043] Reference Figures 1 to 4This embodiment provides a cutting bed sorting system. The cutting surface of the cutting bed is sequentially divided into a cutting area 2 and a sorting area 1 according to the fabric's transport direction from inlet to outlet (the fabric is transported from the cutting area 2 to the sorting area 1). The cutting bed sorting system includes:

[0044] The sorting module is used to sort the cut pieces 3 on the sorting area 1;

[0045] A shearing module is used to cut off excess material along a fixed shearing path, said shearing path being a straight line (e.g., ...). Figure 1 (As shown by the dashed line); the cutting path is the boundary line between the cutting area and the picking area, or the cutting path is located in the picking area;

[0046] The control module is used to control the operation of the picking module and the cutting module;

[0047] While the sorting module is sorting the cut pieces, the cutting area is simultaneously performing the cutting operation.

[0048] Specifically, there are generally two types of cutting bed systems: one where the fabric is laid out again after one batch is cut, and the fabric does not move during cutting; and the other where the cutting process is continuous, with the fabric still in motion. In the continuous cutting bed system, the remaining material is constantly being cut and recycled.

[0049] In this embodiment, the cutting surface of the cutting bed is divided into two areas: cutting area 2 and picking area 1. While the picking module picks up the cut pieces in picking area 1, cutting area 2 simultaneously cuts. After both are completed, the conveying device of the cutting bed sends the fabric located in cutting area 2 to picking area 1. The remaining material left after the cut pieces were picked up in picking area 1 is then transferred along... Figure 1 The dotted line should be cut off and recycled.

[0050] In this embodiment, the picking module includes multiple picking units; the picking module operates in two modes: a single picking mode and a double picking mode. In the single picking mode, all picking units pick up cut pieces according to a first method. In the double picking mode, the picking units are divided into two groups: the first group picks up cut pieces that intersect with the cutting path according to a second method, and the second group picks up the remaining cut pieces according to the first method. The first method involves two picking units cooperating to pick up two cut pieces, while the second method involves each picking unit picking up one cut piece independently.

[0051] In this embodiment, the system first determines whether there is a piece 3 on the cutting path of the cutting module. The determination method is as follows: the cutting path is always a straight line at a fixed position. The system determines whether the straight line intersects with the outer contour curve of the piece 3 (the database stores the outer contour data and position data of the pre-cut pieces; the horizontal coordinate of the straight line remains unchanged, so it is only necessary to traverse the outer contour data and find the data with the same horizontal coordinate as the straight line to find the piece corresponding to that data). If the number of intersection points n = 0, the control module controls the picking module to perform single picking mode; if the number of intersection points n > 0, the control module controls the picking module to switch to double picking mode. After picking is completed, the cutting module cuts off the remaining material along a specific straight line.

[0052] In this embodiment, the sorting unit includes a telescopic rotating rod 6, a telescopic rod 5, and a suction cup 4. The telescopic rotating rod 6 can slide along the track 7 and can extend and retract in the longitudinal direction, as well as rotate around its own axis. The telescopic rod 5 is connected to the lower end of the telescopic rotating rod 6 and can extend and retract in the horizontal direction. The suction cup 4 is rotatably connected to the end of the telescopic rod 5. The control module controls the movements of the telescopic rotating rod 6, the telescopic rod 5, and the suction cup 4 to make the suction cup 4 reach a preset piece suction position. In this embodiment, the telescopic rod 5 has two ends, each end of which is connected to a suction cup 4, and the two suction cups 4 work independently. The telescopic rod 5 can control the distance between the two suction cups 4, and the telescopic rotating rod 6 can control the height of the suction cup 4 and the horizontal angle of the telescopic rod 5.

[0053] In this embodiment, the suction cup 4 is equipped with a displacement sensor to collect its position coordinates, thereby matching the position of the suction cup 4 with a preset piece adsorption position through the control module. One suction cup 4 can be positioned to the preset piece adsorption position first, and then the extension and retraction of the telescopic rod 5 and the rotation of the telescopic rotating rod 6 can move the other suction cup 4 to the preset adsorption position (at this time, the piece moves horizontally under the drive of the cutting bed's conveyor device, and the picking unit needs to move horizontally synchronously with the piece). For a cutting bed system that cuts while moving, the position of the piece 3 changes constantly, so the positioning of the suction cup 4 also needs to include time data, adsorbing the piece 3 at a specific position at a specific time.

[0054] The operation of the picking module under different modes will now be explained:

[0055] In single-pickup mode: see Figure 3Instead of using a single picking unit to pick up a single piece of fabric 3, two picking units are used to pick up two pieces of fabric 3 together. Two suction cups 4 of the same picking unit adhere to the same side of two adjacent pieces of fabric 3, and the suction position is adjusted by a telescopic rod 5 and a telescopic rotating rod 6. Advantages: The distance between adjacent pieces of fabric 3 is smaller, and the length required for the picking unit to span two pieces of fabric 3 is also smaller. If one picking unit is used to pick up one piece of fabric 3, the distance between the two suction cups 4 needs to be adjusted using the telescopic rod 5 to accommodate the length of the piece of fabric 3. The telescopic rod 5 requires a longer telescopic distance, increasing the device size and greatly limiting the number of picking units that can be accommodated in the upper space of the cutting bed. Furthermore, the picking unit needs to travel a certain distance to deliver the piece of fabric to the designated position. The cutting speed of the piece of fabric, the picking speed of the picking unit, the conveying speed, and the conveying distance need to be coordinated to achieve the optimal production speed. If the number of picking units is small, the picking speed will limit the distance between the cutting bed and the area accommodating the piece of fabric when arranging the factory area. The picking method in this embodiment increases the freedom of arrangement for each area.

[0056] In dual-pickup mode: Since there may not be other cut pieces nearby that intersect with the cutting path, in order to achieve... Figure 3 The picking method shown is used, therefore... Figure 4 As shown, one picking unit picks up one piece 3. The picking module is divided into two groups: one group picks up pieces 3 that intersect with the cutting path (hereinafter referred to as transition pieces) according to the second method, and the other group picks up the remaining pieces according to the first method. The picking units responsible for picking up transition pieces are always fixed to a few specific units, and the remaining picking units only need to maintain a single picking mode. That is, the mode switching of the picking module is only the switching of the picking methods of these fixed picking units. When each picking unit picks up one piece of fabric individually, the control is simple, and it has a faster response and execution speed, and can quickly pick up all the pieces of fabric on the cutting path.

[0057] In this embodiment, when arranging the cut pieces, only the cut pieces required for the same garment are cut from the same fabric. This way, when transporting the cut pieces, they can be transported to the same holding area, avoiding the problem that the cut pieces collected by the two picking units are located in different cutting areas and the transportation distance is too long.

[0058] In this embodiment, the switching of the picking module's working mode, combined with a specific picking unit structure, improves picking efficiency and increases the maximum number of picking units that can be set. The conventional, uniform picking method for cut pieces has been improved, resulting in two different picking modes, each responsible for the cut pieces intersecting the cutting line and the remaining cut pieces. In single-picking mode, the specific picking method significantly reduces the volume of the picking unit, thus accommodating larger picking distances and faster cutting speeds, providing greater freedom for process optimization. In dual-picking mode, when a picking unit picks up a single cut piece, it has a faster response and execution speed, quickly picking up all cut pieces along the cutting path.

[0059] The scrap cutting line no longer needs to be specifically generated; the dividing line between the cutting area and the picking area is used uniformly as the cutting line, making the cutting operation more convenient.

[0060] Another embodiment of the present invention provides a cutting bed, including the cutting bed sorting system described in embodiment 1.

Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
