Description

Technical Field

[0001] This invention belongs to the field of garment processing technology, and relates to a garment fabric twisting device, and more particularly to an automatic garment fabric separation device. Background Technology

[0002] The garment processing industry is a labor-intensive industry, relying heavily on manual labor, leading to rising costs. While patent document CN202020851827.4 provides a needle-punched garment piece grasping device, its principle involves first "grabbing" the numbered garment pieces through needle punching, then transferring them to a predetermined position. However, this fabric separation device easily leaves needle holes in the fabric, affecting the quality of the processed garments. Furthermore, existing technologies also include air-blowing pipes on numbering machines, but using these pipes to lift and flip the fabric pieces can easily result in flipping too many pieces at once, leading to poor accuracy. Therefore, this method cannot be formally applied to numbering machines. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic garment fabric separation device to solve the technical problem in the prior art that it is impossible to accurately grasp and flip the fabric without damaging it.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] An automatic garment fabric separation device includes a support plate, a control box, and a marking mechanism, a fabric-spinning mechanism, and a gripping mechanism disposed on the support plate and connected to the control box. The marking mechanism is disposed on the front side of the support plate. The fabric-spinning mechanism includes a spinning drive part and a spinning transmission connection part connected thereto. The spinning transmission connection part is rotatably connected to the support plate. The gripping mechanism is disposed at the output end of the spinning transmission connection part and has the freedom to spin along the output end of the fabric piece under the drive of the spinning transmission connection part.

[0006] The fabric-spinning mechanism includes a fabric-spinning cylinder, a transmission link, a gripper cylinder base, a gripper assembly plate, a bearing seat, and a gripper transmission shaft. The gripper transmission shaft is mounted on the rear side of the support plate via the bearing seat and the gripper assembly plate. The fixed end of the fabric-spinning cylinder is fixed to the side of the support plate via a connecting plate, and the telescopic end is hinged to one end of the transmission link via a connector. The other end of the transmission link is hinged to one end of the gripper cylinder base. One end of the gripper transmission shaft passes through the bearing seat and is keyed to the middle of the gripper cylinder base, while the other end is fixed with a gripping mechanism.

[0007] The gripping mechanism includes a support plate, a slide connecting plate, a slide cylinder, and a gripper portion disposed on the slide of the slide cylinder, which are fixedly connected in sequence. The slide cylinder is vertically arranged and drives the gripper portion on its slide to slide up and down relative to the body of the slide cylinder. The support plate is disposed on the gripper drive shaft and is keyed to the gripper drive shaft.

[0008] A position detector is provided on the side of the cylinder body of the slide cylinder, and a magnetic ring is provided on the slide. The position detector is electrically connected to the control box and detects the position of the slide relative to the cylinder body by detecting the change of the magnetic field of the magnetic ring relative to the position detector.

[0009] The gripper part includes gripper side plates, gripper cylinders, gripper cylinder connectors, gripper connecting rods, gripper rotating blocks, gripper friction blocks, and gripper fixing backing blocks. There are two gripper side plates, which are respectively fixed on both sides of the slide in the slide cylinder. The gripper cylinder and the gripper fixing backing blocks are respectively fixed on both sides of the gripper side plates. One end of the gripper cylinder connector is fixed to the telescopic end of the gripper cylinder, and the other end is hinged to one end of the gripper connecting rod. One end of the gripper rotating block is hinged to the other end of the gripper connecting rod, and the middle part is hinged to the two gripper side plates. The gripper friction block is fixed on the gripper rotating block on the opposite side of the gripper connecting rod. The gripper friction block and the gripper fixing backing block are arranged opposite each other to form the gripper body.

[0010] The gripper portion also includes a clamping block, which is fixed to the clamping surface of the gripper fixing backing block, and the gripper friction block contacts the side of the clamping block in a vertical state.

[0011] The gripper also includes a pressure sensor and a sensor bracket. The sensor bracket is fixed to the side of the gripper fixing block and located on the opposite side of the gripper friction block. Both the gripper friction block and the gripper rotating block are provided with through slots. The fixed end of the pressure sensor is set on the sensor bracket, and the sensing end passes through the through slots of the gripper friction block and the gripper rotating block and then contacts one side of the clamping surface in the gripper friction block.

[0012] It also includes an air-blowing auxiliary fabric turning mechanism set on the support plate. The air-blowing auxiliary fabric turning mechanism includes an air-blowing bend fixed on the support plate by an air-blowing auxiliary bracket. The air inlet of the air-blowing bend is connected to an external air pump, and the air outlet of the air-blowing bend points to the material outlet side of the marking mechanism. The air outlet of the air-blowing bend is located between two vertical planes of the gripper body when it is in its original position and when it is thrown to the highest position.

[0013] The gripper cylinder is a stroke-adjustable cylinder.

[0014] An electromagnetic valve is installed on the air blowing bend, and the electromagnetic valve is electrically connected to the control box.

[0015] The beneficial effects of adopting the above technical solution are as follows:

[0016] This invention provides an automatic garment fabric separation device, used in the process of numbering garment fabric pieces. The device automatically grips and flips the fabric pieces, and the numbering machine numbers the fabric pieces. After the numbering is completed, the slide cylinder drives the gripper to slide down to contact the surface of the fabric piece. The gripper cylinder moves to drive the gripper body to perform a gripping action. The gripper friction block moves relative to the surface of the fabric piece to generate friction. Under the action of friction, the fabric piece wrinkles and is clamped by the gripper body. After the fabric piece is clamped, it is lifted up as the slide cylinder rises. A pressure sensor is installed to detect the pressure of the gripper friction block in real time during the gripping state. Based on the pressure, it is determined whether the gripper body has gripped one piece of fabric, zero pieces of fabric, or two or more pieces of fabric. When the detected pressure exceeds or falls below the pressure value when gripping one piece of fabric, the gripper cylinder drives the gripper friction block to loosen relative to the gripper fixing block and then re-grip and pick up the fabric. The pressure sensor re-detects the pressure of the gripper friction block. When the detected pressure is within the set range, the fabric-swinging cylinder in the fabric-swinging mechanism retracts, driving the gripping mechanism to perform a throwing action. When the fabric-swinging cylinder retracts to its final position, the gripper cylinder drives the gripper friction block to loosen. After the fabric is successfully flipped over by the air blowing and flipping mechanism, the fabric-swinging cylinder drives the gripping mechanism to reset, waiting for the next fabric to be picked up.

[0017] The technical solution provided by this invention can automate the fabric turning process, with high grasping accuracy and no damage to the fabric pieces. It can significantly improve the marking efficiency of the marking machine and significantly reduce the manual dependence on fabric marking, making it suitable for widespread promotion and application in the marking process of garment fabric pieces.

[0025] To better understand the purpose, structure, and function of this invention, a clear and complete description of the invention is provided below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 3 As shown, this invention provides an automatic garment fabric separation device, which is installed on and used in conjunction with a fabric marking machine. In this embodiment, it includes a support plate 1, a control box, and a marking mechanism 2, a fabric throwing mechanism 3, and a gripping mechanism 4, all installed on the support plate 1 and connected to the control box. The marking mechanism 2 is located on the front side of the support plate 1. In this embodiment, the marking component disclosed in patent application CN216033275U is used, and a PLC controller is installed in the control box to control the action commands of each component in the device. The fabric throwing mechanism 3 includes a throwing drive part and a throwing transmission connection part connected to it. The throwing transmission connection part is rotatably connected to the support plate 1. The gripping mechanism 4 is located at the output end of the throwing transmission connection part and has the freedom to throw along the output end of the fabric piece under the drive of the throwing transmission connection part. After the marking mechanism 2 completes the marking, the control box controls the gripping mechanism 4 to grab the fabric piece. After the gripping is completed, the control box controls the fabric throwing mechanism 3 to swing the gripping mechanism 4 to the highest point. At the same time, the gripping mechanism 4 releases the fabric piece, and the grabbed fabric piece is flipped to the discharge side of the marking machine, thereby separating the marked fabric piece from the fabric piece to be marked.

[0027] Specifically, such as Figures 2 to 4As shown, the fabric-throwing mechanism 3 includes a fabric-throwing cylinder 5, a transmission link 6, a gripper cylinder base 7, a gripper assembly plate 8, a bearing seat 9, and a gripper drive shaft 10. The gripper drive shaft 10 is mounted on the rear side of the support plate 1 via the bearing seat 9 and the gripper assembly plate 8. The fixed end of the fabric-throwing cylinder 5 is fixed to the side of the support plate 1 via a connecting plate 11, and the telescopic end is hinged to one end of the transmission link 6 via a connector. The other end of the transmission link 6 is hinged to one end of the gripper cylinder base 7. One end of the gripper drive shaft 10 passes through the bearing seat 9 and is keyed to the middle of the gripper cylinder base 7; the other end is fixed with a gripping mechanism 4. During the fabric-throwing action, the fabric-throwing cylinder 5 retracts, driving the gripper drive shaft 10 to rotate around its own axis via the transmission link 6 and the gripper cylinder base 7. The rotating gripper drive shaft 10 causes the gripping mechanism 4 fixed on it to swing to a high position, thus throwing the fabric outwards.

[0028] In addition, such as Figure 3 , Figure 4 , Figure 5 As shown, the gripping mechanism 4 includes a support plate 12, a slide connecting plate 13, a slide cylinder 14, and a gripper portion 15 disposed on the slide 141 of the slide cylinder 14, which are fixedly connected in sequence. The slide cylinder 14 is vertically arranged, driving the gripper portion 15 on its slide 141 to slide up and down relative to the body of the slide cylinder 14, so as to lower the gripper portion 15 to the height of the marking fabric piece. The support plate 12 is disposed on the gripper drive shaft 10 and is keyed to the gripper drive shaft 10 for transmission. However, since the gripping mechanism 4 can easily be worn by driving it to swing through the keyed connection between the support plate 12 and the gripper drive shaft 10 alone, this embodiment uses a base connecting plate 71 to fix the support plate 12 and the gripper cylinder base 7. When the fabric-spinning cylinder 5 is working, it uses the gripper drive shaft 10 and the base connecting plate 71 to drive the support plate 12, which can significantly reduce the frictional resistance of the gripper drive shaft 10 during the transmission process, reduce its wear, and extend its service life.

[0029] Furthermore, in order to facilitate the identification of whether the slide cylinder 14 has extended to the correct position, so that the gripper 15 can automatically increase its stroke as the fabric becomes thinner during the marking process, thereby ensuring that the gripper 15 can successfully grasp the fabric when making the releasing and clamping actions, in this embodiment, a position detector is provided on the side of the cylinder body of the slide cylinder 14, and a magnetic ring is provided on the slide 141. The position detector is electrically connected to the control box and detects the position of the slide 141 relative to the cylinder body by detecting the change in the magnetic field of the magnetic ring relative to the position detector.

[0030] In this embodiment, the working process of the slide cylinder is as follows:

[0031] Before marking the first piece of fabric in a stack, the height of the fabric to be marked needs to be determined. The method is as follows: the slide cylinder 14 drives the gripper 15 to sink down to contact the fabric. Under the reverse force of the fabric, it rebounds a small distance, and the magnetic field of the magnetic ring relative to the position detector changes. This triggers the position detector to transmit a signal to the control box to obtain the height position of the fabric. Then, the gripper 15 is lifted, and the marking mechanism 2 marks the fabric. After marking is completed, the slide cylinder 14 drives the slide 141 and the gripper 15 on it to sink down to complete the fabric clamping action. After the fabric is clamped in place, the slide cylinder 14 retracts and drives the gripper 15 to move. The fabric throwing cylinder 5 drives the gripper 15 to throw the fabric outward.

[0032] After the first piece of fabric is thrown out, starting with the second piece, the marking mechanism 2 directly marks the fabric pieces. After marking, the slide cylinder 14 drives the gripper 15 to sink until it contacts the fabric piece and rebounds slightly. The position detector triggers a detection signal, which is transmitted to the PLC controller in the control box. Upon receiving the detector signal, the control box initiates the single-layer fabric gripping action. Since the marking mechanism 2 has sufficient leeway during its operation, gripping the fabric piece will not affect the marking process; therefore, height compensation is not required.

[0033] Furthermore, such as Figure 5 , Figure 6As shown, the gripper part 15 includes gripper side plates 16, gripper cylinders 17, gripper cylinder connectors 18, gripper connecting rods 19, gripper rotating blocks 20, gripper friction blocks 21, and gripper fixing blocks 22. Two gripper side plates 16 are respectively fixed to both sides of the gripper part mounting plate 142. These plates are mounted on both sides of the slide 141 in the slide cylinder 14 via the gripper part mounting plate 142, and are used to fix other components of the gripper part 15 to the slide 141 of the slide cylinder 14. The gripper cylinders 17 and 18 are also included. The two sides of the claw fixing support block 22 are respectively fixed on the claw side plate 16. One end of the claw cylinder connector 18 is fixed to the telescopic end of the claw cylinder 17, and the other end is hinged to one end of the claw connecting rod 19. One end of the claw rotating block 20 is hinged to the other end of the claw connecting rod 19, and the middle part is hinged to the two claw side plates 16. The claw friction block 21 is fixed on the claw rotating block 20 on the opposite side of the claw connecting rod 19. The claw friction block 21 and the clamping surface of the claw fixing support block 22 are arranged opposite to each other to form the claw body. By utilizing the hinges of the gripper cylinder connector 18, gripper connecting rod 19, and gripper rotating block 20, as well as the hinge between the gripper rotating block 20 and the gripper side plate 16, the gripper friction block 21 is driven to swing relative to the gripper fixed support block 22, thereby enabling the gripper body to complete the release-clamping action. The specific action process is as follows: the gripper cylinder 17 drives the gripper cylinder connector 18 to extend and sink, the upper end of the gripper connecting rod 19 swings around the hinge axis with the gripper cylinder connector 18, and drives the gripper rotating block 20, which is hinged to the lower end of the gripper, to swing around the hinge axis with the lower end of the gripper connecting rod 19. Under the action of the swinging of one side of the gripper rotating block 20, the middle part of the gripper rotating block 20 swings around the hinge axis with the gripper side plate 16, thereby driving the gripper friction block 21, which is fixed to the gripper rotating block 20, to perform the release-clamping action relative to the gripper fixed support block 22. In order to make the degree of loosening of the gripper friction block 21 relative to the gripper fixing backing block 22 adjustable so as to adapt to and grip fabrics of different thicknesses and broaden its application range, the gripper cylinder 17 in this embodiment is a stroke adjustable cylinder. When it is necessary to grip fabrics of other thicknesses, the stroke of the gripper cylinder 17 can be quickly adjusted.

[0034] Furthermore, such as Figure 5 , Figure 6 As shown, when it is necessary to clamp a piece of fabric with a significantly different thickness than before, in order to improve the clamping accuracy, the gripper part 15 in this embodiment also includes a pressing block 23. The pressing block 23 is fixed on the clamping surface of the gripper fixing backing block 22. When it is necessary to clamp a piece of fabric with a smaller thickness, the gripper friction block 21 contacts the side of the pressing block 23 in a vertical state. When it is necessary to clamp a piece of fabric with a larger thickness, the pressing block 23 with a smaller thickness can be selected or replaced according to the actual situation, so that there is a certain gap between the clamping surface of the pressing block 23 and the gripper friction block 21, so as to ensure that the gripper body can fully clamp a piece of fabric with a larger thickness.

[0035] Furthermore, to improve the gripping accuracy of the gripper body and avoid over-gripping or missed gripping, ensuring that each piece of clothing fabric is numbered once, the gripper part 15 also includes a pressure sensor 24 and a sensor bracket 25 electrically connected to the control box. The sensor bracket 25 is fixed to the side of the gripper fixing support block 22, located opposite the gripper friction block 21. Both the gripper friction block 21 and the gripper rotating block 20 are provided with through slots. The fixed end of the pressure sensor 24 is mounted on the sensor bracket 25, and the sensing end passes through the through slots of the gripper friction block 21 and the gripper rotating block 20, contacting one side of the clamping surface of the gripper friction block 21. The pressure sensor 24 detects the pressure exerted on it by the gripper friction block 21 in real time and transmits the pressure data to the control box in real time, allowing the control box to determine whether to issue a fabric-throwing command or a command to loosen and re-clamp the gripper body. In this embodiment, since the control box needs to process and analyze the data collected by the sensor, a PLC controller is selected in the control box.

[0036] Furthermore, such as Figure 1 , Figure 2 As shown, in order to enable the fabric piece gripped by the gripper body to be smoothly flipped over under the action of the fabric-throwing mechanism 3, an air-blowing auxiliary fabric-flipping mechanism is also provided on the support plate 1 in this embodiment. The air-blowing auxiliary fabric-flipping mechanism specifically includes an air-blowing bend pipe 27 fixed on the support plate 1 by an air-blowing auxiliary bracket 26. The air inlet end of the air-blowing bend pipe 27 is connected to an external air pump, and the air outlet end points to the material outlet side of the marking mechanism 2. The air outlet of the air-blowing bend pipe 27 is located between the two vertical planes when the gripping surface of the gripper body is in its original position and when it is thrown to the highest position. In addition, a solenoid valve is provided on the air-blowing pipe 27 and connected to the PLC controller so that the air-blowing pipe 27 blows air intermittently. When the fabric piece is brought to the highest position by the gripper body, the PLC controller controls the solenoid valve to open and blow air between the gripped fabric piece and the fabric piece to be numbered. At the same time, the gripper body releases the gripped fabric piece. Under the combined action of the swinging action of the fabric swinging mechanism 3 and the blowing action of the air blowing bend 27, the fabric piece is successfully flipped over.

[0037] Finally, all cylinders mentioned in this embodiment are connected to an external air pump, and the external air pump and other electrical components are electrically connected to the control box. This is something that those skilled in the art can do, and will not be described in detail in this embodiment.

[0038] It is understood that the present invention has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. Furthermore, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of the present invention.
