Description

Technical Field

[0001] This invention relates to the field of cutting technology, specifically to an intelligent cutting machine, cutting method, and control system adaptable to various types of leather. Background Technology

[0002] Currently, existing leather cutting machines typically only have a single cutting function. Their workflow is generally as follows: the feeding mechanism transports the entire piece of leather to the cutting table, and the vibrating blade completes the cutting according to the preset layout trajectory. After that, the finished product on the cutting table and the surrounding waste (edges and scraps) remain in their original flat, spread-out state.

[0003] Due to the lack of a follow-up sorting mechanism, existing equipment requires manual operation after the cutting process. Workers must manually pick out numerous finished pieces from the waste grid one by one, and then manually remove the remaining waste. This manual sorting method significantly reduces leather production efficiency. Summary of the Invention

To solve these problems, this invention employs the following technical solutions: A smart cutting machine adaptable to various types of leather includes a conveyor belt device, a movable cutting part movably connected to the conveyor belt device, a cylinder and an image acquisition device fixedly connected to the conveyor belt device, a connecting frame fixedly connected to the piston rod of the cylinder, four lifting and clamping components connected to the connecting frame, and a controller movably connected to the conveyor belt device.

A lifting seat is connected to the connecting plate, and a horizontal slide is slidably connected to the lifting seat. The horizontal slide is connected to the lifting seat via a spring, and a sliding member is slidably connected to the horizontal slide. A commutator is fixedly connected to the sliding member, and a third gear is fixedly connected to the input shaft of the commutator. A frame is fixedly connected to the output shaft of the commutator. Two claws are rotatably connected to the sliding member via an automatic reset shaft. Two clamping plates are slidably connected to the lifting seat, and threaded holes are provided on the clamping plates. A first gear is rotatably connected to the lifting seat, and a bidirectional screw is fixedly connected to the first gear. The bidirectional screw is threadedly connected to the threaded hole. A wedge-shaped block is fixed to the sliding member, and a first rack is fixedly connected to the connecting plate.

[0006] Optionally, the lifting and clamping assembly further includes a lifting frame, a second gear, and a second rack. The lifting frame is slidably connected to the connecting plate, and the lifting seat is slidably connected to the lifting frame. A through hole is provided on the lifting frame. The second gear is rotatably connected to the connecting plate, and a push column is rotatably connected to the second gear. The push column is slidably connected to the inner wall of the through hole, and the second rack is fixed to the conveyor belt device.

[0007] Optionally, the lifting frame is in the shape of a C.

[0008] Optionally, the wedge-shaped bar is fixedly connected to the connecting plate through the first extension bar, the top bar is fixedly connected to the connecting plate through the second extension bar, and the third rack is fixedly connected to the connecting plate through the third extension bar.

[0009] Optionally, a T-shaped frame is fixedly connected to the slider, and the rotating claw is rotatably connected to the T-shaped frame through the automatic reset rotating shaft.

[0010] Optionally, the controller includes a touch screen display.

[0011] Optionally, a display monitor is fixedly connected to the conveyor belt device.

[0012] An intelligent cutting method adaptable to various leathers, using the intelligent leather cutting machine adaptable to various leathers to cut leather, includes the following steps: Step 1: Place the leather on the conveyor belt device; Step 2: Obtain the surface image of the leather to be cut through the image acquisition device; Step 3: The controller identifies the leather contour and the defect area according to the surface image and generates a cutting path; Step 4: The controller controls the active cutting part to perform a cutting action on the leather according to the cutting path, so that the leather is separated into finished products and waste; Step 5: The controller controls the four lifting and clamping components to clamp the waste, the controller controls the first cylinder to drive the connecting frame, the lifting and clamping components, and the waste to move upward, the waste and the finished product are separated, and the finished product stays on the conveyor belt device; Step 6: The controller controls the conveyor belt device to transport the finished product to one side of the conveyor belt device and then separate it from the conveyor belt device, Step 7: The controller controls the lifting and clamping components to release the clamping of the waste, the waste falls on the conveyor belt device, and the controller controls the conveyor belt device to transport the waste to the other side of the conveyor belt device and then separate it from the conveyor belt device.

[0013] An intelligent leather cutting machine control system adaptable to various leathers, used to control the intelligent leather cutting machine adaptable to various leathers, includes a processor provided in the controller.

[0014] The present invention has the following beneficial effects: The leather is carried by a conveyor belt and the cutting contour is identified by an image acquisition device. The controller generates the cutting path and controls the moving cutting part to complete the precise cutting, so that the leather is directly separated into finished products and waste in the same station. In order to solve the problem that the finished products and waste are still in a flat mixed state after cutting and must be sorted manually piece by piece, the cylinder drives the connecting frame and four lifting and clamping components to move synchronously. The rotating claw can temporarily clamp a small area of ​​waste under the action of the frame and the reversing device. With the help of wedge blocks and wedge strips, the waste is locally lifted to form a gap that facilitates the insertion of the subsequent clamping plate, which can then clamp the whole piece of waste. The directional clamping control of the claw is achieved through the cooperation of rack three, gear three, and commutator. Then, gear one and rack one drive the bidirectional screw, so that the clamping plate synchronously clamps and positions the edge of the waste material. In conjunction with gear two and rack two, the lifting frame is driven to form reverse reciprocating vibration on the connecting plate. Under the continuous vibration, the finished products nested inside the waste material are gradually detached and fall onto the conveyor belt device. Finally, the conveyor belt device transports the finished products and waste materials to the two ends of the conveyor belt device respectively, realizing the automatic separation and automatic classification and collection of waste materials and finished products, reducing manual intervention, improving automation effect, and improving leather production efficiency.

[0018] 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.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0021] like Figures 2-5 As shown, an intelligent cutting machine adaptable to various types of leather includes a conveyor belt device 1, a movable cutting part 2 movably connected to the conveyor belt device 1, a cylinder 3 and an image acquisition device fixedly connected to the conveyor belt device 1, a connecting frame fixedly connected to the piston rod of the cylinder 3, four lifting and clamping components connected to the connecting frame, and a controller movably connected to the conveyor belt device 1.

[0022] The system includes a conveyor belt 1 for carrying the leather and conveying finished products and waste materials after cutting; a movable cutting section 2 for cutting the leather according to the cutting path; a cylinder 3 for driving the connecting frame and four lifting and clamping components to lift and lower as a whole, so as to avoid the movable cutting section 2 during cutting and to move the waste materials upward during sorting; an image acquisition device for acquiring images of the leather surface for the controller to identify the leather outline and defect areas; and a controller for generating a cutting path based on the image information and coordinating the movable cutting section 2, cylinder 3, conveyor belt 1, and lifting and clamping components to complete the cutting, separating, and conveying actions.

[0023] Optionally, the tool holder on the movable cutting section 2 is an integrated tool holder that combines cutting, drawing, punching, and punching, which is efficient, precise, and simple.

[0024] The high-frequency pneumatic blade on the blade holder can cut various materials such as leather, PU, ​​microfiber, mesh, and PVC.

[0025] Cut leather can be made from various types of leather materials, including natural leather, synthetic leather, artificial leather, composite leather, soft leather, hard leather, thick leather, or thin leather. Leather can be used to produce shoe uppers, insoles, shoe tongues, handbags, wallets, backpacks, handbags, belts, leather clothing, automotive interiors, furniture upholstery, or other leather products.

[0026] It is worth noting that leather often uses metals such as aluminum, zirconium, and titanium as tanning agents, which makes the leather contain metals and also makes it more durable. This invention also relates to the field of metal cutting in leather cutting. In the manufacturing of the cutting machine, each component, such as the conveyor belt device 1, the movable cutting part 2, the cylinder 3, the connecting frame, the lifting and clamping assembly, and the controller, is independently processed and manufactured, and then assembled with the help of tools.

[0027] Based on the above scheme, in some optional embodiments, the lifting and clamping assembly includes a connecting plate 4, on which a second cylinder 5, a wedge-shaped strip 21, a top strip 22, and a third rack 23 are fixedly connected. A lifting seat 6 is connected to the connecting plate 4, and a horizontal slide 7 is slidably connected to the lifting seat 6. The horizontal slide 7 is connected to the lifting seat 6 via a spring 71. A sliding member 8 is slidably connected to the horizontal slide 7, and a commutator 11 is fixedly connected to the sliding member 8. A gear is fixedly connected to the input shaft of the commutator 11. Wheel 3 (24), a frame 10 is fixedly connected to the output shaft of commutator 11. Two pawls 9 are rotatably connected to the slide 8 via an automatic reset shaft. Two clamping plates 12 are slidably connected to the lifting seat 6, each with threaded holes. A gear 14 is rotatably connected to the lifting seat 6, and a bidirectional screw 15 is fixedly connected to the gear 14, threadedly connected to the threaded holes. A wedge block 25 is fixedly connected to the slide 8, and a rack 13 is fixedly connected to the connecting plate 4. The automatic reset shaft allows the pawls 9 to automatically reverse and reset after the external force causing them to rotate is released. Gear 14 drives the bidirectional screw 15 to rotate; the bidirectional screw 15 drives the two clamping plates 12 to move synchronously closer or further apart, achieving clamping or releasing of the waste material edge.

[0028] The horizontal slide 7 can only slide horizontally on the lifting seat 6. The slide 8 can only move vertically on the horizontal slide 7.

[0029] In a preferred embodiment, the lifting and clamping assembly further includes a lifting frame 16, a second gear 18, and a second rack 20. The lifting frame 16 is slidably connected to the connecting plate 4, and the lifting seat 6 is slidably connected to the lifting frame 16. A through hole 17 is provided on the lifting frame 16. The second gear 18 is rotatably connected to the connecting plate 4, and a push column 19 is rotatably connected to the second gear 18. The push column 19 is slidably connected to the inner wall of the through hole 17, and the second rack 20 is fixedly connected to the conveyor belt device 1.

[0030] The lifting frame 16 is used to support the lifting seat 6 and drive the edge of the clamped waste material to move up and down reciprocally; the rack 20 is used to mesh with the gear 18 when the connecting plate 4 moves up with the cylinder 3, thereby driving the gear 18 to rotate; the gear 18 is used to drive the push column 19 to make eccentric movements; the push column 19 is used to slide in the through hole 17 and push the lifting frame 16 to move up and down reciprocally; the through hole 17 is used to provide sliding fit space for the push column 19, so that the rotation of the gear 18 can be converted into the up and down vibration of the lifting frame 16, thereby shaking off the finished product nested in the waste material.

[0031] Note that the rotating connections of frame 10, gear 14, gear 28, and gear 324 all have a certain damping force, so that the above components will not easily rotate unnecessarily after rotating to the appropriate position.

[0032] The lifting frame 16 can only move up and down on the connecting plate 4, and the lifting seat 6 can only slide horizontally along the lifting frame 16.

[0033] In an alternative embodiment, the lifting frame 16 is in the shape of a C.

[0034] In some embodiments, the wedge-shaped strip 21 is fixedly connected to the connecting plate 4 through the first extension strip, the top strip 22 is fixedly connected to the connecting plate 4 through the second extension strip, and the third rack 23 is fixedly connected to the connecting plate 4 through the third extension strip.

[0035] Regarding the setting of the rotating claw 9, a T-shaped frame is fixedly connected to the sliding member 8, and the rotating claw 9 is rotatably connected to the T-shaped frame through the automatic reset rotating shaft.

[0036] Note that the controller includes a touch screen display. The touch screen display is used to display leather images, cutting paths, equipment status, and operating parameters, and allows operators to input control commands or adjust cutting and sorting parameters.

[0037] In addition, a display monitor is fixedly connected to the conveyor belt device 1. The display monitor is used to externally display the equipment operating status, cutting progress, sorting status, or processing information, facilitating other personnel in the distance to observe the equipment status in real time.

[0038] In some alternative embodiments, the controller can determine the effective utilization rate of leather based on the leather surface image and optimize the cutting path according to the effective utilization rate of leather. The effective utilization rate η of leather satisfies the following formula: η = A / B × 100% Where η is the effective utilization rate of leather; A is the total area of finished products calculated by the controller according to the cutting path; B is the area of the leather cuttable region recognized by the controller from the surface image collected by the image acquisition device, and the area of the leather cuttable region does not include the area of the defect region. Through the above formula, the controller can judge the utilization degree of the current cutting path for leather, and when there are multiple optional cutting paths, preferentially select the cutting path with a higher effective utilization rate η of leather, thereby reducing the waste area and improving the utilization rate of leather materials.

[0039] As Figure 1 shown, a smart cutting method adaptable to multiple leathers uses the above-mentioned smart leather cutter adaptable to multiple leathers to cut leather, including the following steps: Step 1: Place the leather on the conveyor belt device 1; Step 2: Obtain the surface image of the leather to be cut through the image acquisition device; Step 3: The controller recognizes the leather contour and defect region according to the surface image and generates a cutting path; Step 4: The controller controls the active cutting part 2 to cut the leather according to the cutting path, so that the leather is separated into finished product and waste material; Step 5: The controller controls the four lifting and clamping components to clamp the waste material. The controller controls the cylinder 3 to drive the connecting frame, lifting and clamping components, and waste material to move upward. The waste material and finished product are separated, and the finished product stays on the conveyor belt device 1. Step Six: The controller controls the conveyor belt device 1 to transport the finished product to one side of the conveyor belt device 1 and then detaches it from the conveyor belt device 1; Step 7: The controller controls the lifting and clamping components to release the gripping of the waste material, and the waste material falls onto the conveyor belt device 1. The controller controls the conveyor belt device 1 to transport the waste material to the other side of the conveyor belt device 1 and then detach it from the conveyor belt device 1.

[0040] A smart cutting machine control system adaptable to various types of leather, used to control the smart cutting machine adaptable to various types of leather, includes a processor disposed within the controller.

[0041] Implementation process: The leather is placed on conveyor belt 1, and an image acquisition device acquires a surface image of the leather to be cut. The controller identifies the leather outline and defect areas based on the surface image and generates a cutting path. The controller then controls the movable cutting unit 2 to cut the leather according to the cutting path (cylinder 3 controls the raising and lowering of the connecting frame and lifting and clamping components to prevent obstruction of the movement of the movable cutting unit 2), separating the leather into finished product and waste material. Figure 6 As shown; At this point, the finished product and the waste material are still pressed together and have not completely separated. The controller controls the following operations: Cylinder 1 (3) moves the connecting frame and the lifting and clamping assembly down to a suitable position; Cylinder 2 (5) extends, causing the lifting seat 6 to slide horizontally along the lifting frame 16; the claws 9 move above the waste material; first, gear 3 (24) and rack 3 (23) mesh; rack 3 (23) drives gear 3 (24) to rotate; after being reversed by the commutator 11, gear 3 (24) drives the frame 10 to rotate, thereby causing the frame 10 to press down the two claws 9. The two claws 9 rotate around the automatic reset shaft, with their lower ends close to each other. The lower ends of the two claws 9 are inserted into the top wall of the waste material and temporarily clamp the waste material in a small area. The gear 3 24 disengages and the rack 3 23 engages. The two claws 9 maintain the temporary clamping of the waste material in a small area. Then, the wedge block 25 and the wedge strip 21 abut against each other. The wedge block 25 moves up along the inclined surface of the wedge strip 21, thereby causing the slide 8, the claws 9, and the waste material to move upward, so that the edge of the waste material is lifted to form a gap, so that the clamping plate 12 can be inserted later.

[0042] Then, the horizontal slide 7 and the top bar 22 abut against each other to limit the horizontal slide 7. The lifting seat 6 continues to move, and the horizontal slide 7 cannot move. The horizontal slide 7 compresses the spring 71. The pawl 9 maintains its current position so that the edge of the waste material is lifted and the edge of the waste material does not move horizontally. The lower clamping plate 12 is inserted into the gap, and the upper clamping plate 12 moves to the top of the waste material. The gear 14 continues to move horizontally with the lifting seat 6. Then the gear 14 and the rack 13 mesh. The gear 14 is driven by the rack 13 to rotate. The bidirectional screw 15 rotates with the gear 14. The rotation of the bidirectional screw 15 causes the two clamping plates 12 to move closer to each other to clamp the edge of the waste material, thus clamping the entire piece of waste material. A pressure sensor can be set on the clamping plate 12 to detect whether it is clamped firmly. The cylinder 2 5 stops extending.

[0043] Cylinder 3 shortens, causing all lifting and clamping components to move upwards. Gear 18 and rack 20 mesh, and gear 18 is driven to rotate by rack 20. Pusher 19 slides in through hole 17, causing lifting frame 16 to move up and down reciprocally. The movement directions of the two left lifting frames 16 and the two right lifting frames 16 are opposite (i.e., the initial phase difference between the pusher 19 in the left lifting and clamping component and the pusher 19 in the right lifting and clamping component on the corresponding gear 18 is 180°, so that the left and right lifting frames 16 form up and down reciprocating movements in opposite directions). This causes the left and right edges of the waste to move up and down in opposite directions, thereby shaking off the finished products stuck in the waste. All finished products fall onto conveyor belt device 1, the waste moves upwards and detaches from conveyor belt device 1, and then conveyor belt device 1 transports the finished products to one side of conveyor belt device 1. After that, the finished products detach from conveyor belt device 1 and enter the finished product storage box.

[0044] The piston rod of cylinder 3 extends and resets, and then the piston rod of cylinder 5 shortens and resets. According to the above principle, other components will reset, causing the two clamping plates 12 to move away from each other, releasing the clamping of the waste material. The waste material falls onto the conveyor belt device 1. The controller controls the conveyor belt device 1 to transport the waste material to the other side of the conveyor belt device 1. After that, the waste material leaves the conveyor belt device 1 and enters the waste material storage box, completing the leather cutting and automatic separation of finished products and waste materials.

[0045] The beneficial effects of this invention are as follows: The conveyor belt device 1 carries the leather and, in conjunction with the image acquisition device, identifies the cutting contour. The controller generates the cutting path and controls the active cutting part 2 to complete the precise cutting, allowing the leather to be directly separated into finished products and waste materials in the same workstation. To address the problem that the finished products and waste materials are still in a flat and mixed state after cutting and must be sorted manually piece by piece, the cylinder 3 drives the connecting frame and four lifting and clamping components to move synchronously. The rotating claw 9, under the action of the frame 10 and the commutator 11, achieves temporary clamping of a small area of ​​waste material. In conjunction with the wedge block 25 and the wedge strip 21, the waste material is partially lifted to form a gap that facilitates the subsequent insertion of the clamping plate 12, making it convenient for the subsequent clamping plate 12 to clamp the entire piece of waste material. The directional clamping control of the claw 9 is achieved through the cooperation of rack 3 23, gear 3 24 and commutator 11. Then, the bidirectional screw 15 is driven by gear 1 14 and rack 1 13, so that the clamping plate 12 forms a synchronous clamping and positioning of the waste material edge. In conjunction with gear 2 18 and rack 2 20, the lifting frame 16 is driven to form a reverse reciprocating vibration on the connecting plate 4, so that the finished products nested inside the waste material are gradually separated and fall onto the conveyor belt device 1 under the continuous shaking action. Finally, the conveyor belt device 1 transports the finished products and waste materials to both ends of the conveyor belt device 1, realizing the automatic separation and automatic classification and collection of waste materials and finished products, reducing manual intervention, improving automation effect and improving leather production efficiency.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
