Description

Technical Field

[0001] This invention relates to the field of fabric cutting technology, and more specifically, to an automatic fabric sorting device. Background Technology

[0002] Fabric cutting is a key process in the textile, apparel, and home furnishing manufacturing industries. It involves precisely cutting large pieces of fabric into several pieces according to a design pattern for subsequent sewing or processing. Laser cutting machines are one type of cutting machine. They are typically equipped with a vacuum adsorption table to hold the fabric and a CNC system to drive the laser head. Based on computer-aided design layouts, they can cut dozens or even hundreds of pieces of varying shapes and sizes in a single operation at high speed. The sorting of cut fabrics mainly relies on the following methods: manual sorting, which is inefficient, labor-intensive, and prone to errors; robotic vision sorting, which, while highly automated, is complex and costly; and mechanical sorting, which typically divides the cutting table into different areas and uses mechanical structures, such as partition descent, tilting, or pushers, to allow the pieces within each area to slide into corresponding collection containers under gravity or simple external force.

[0003] Existing automatic fabric sorting devices, such as mechanical sorting, have the following drawbacks during use: 1. The high temperature of laser cutting can cause localized melting of the cut edges of thermoplastic fabrics such as synthetic fibers, which easily stick to the table surface after cooling; 2. Static electricity generated during the cutting process can cause thin fabric pieces to adhere tightly to the table surface, severely hindering the smooth sliding and separation of the fabric pieces under gravity; 3. For soft and easily deformable textile fabrics, they are prone to tumbling and folding during the inclined sliding process, resulting in the fabric pieces accumulating in a messy and curled state in the collection box, making subsequent retrieval or manual sorting difficult, and may also cause damage to the fabric pieces. In view of this, we propose an automatic fabric sorting device. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic fabric sorting device to address the aforementioned shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: including a base, wherein the top of the base is symmetrically provided with unloading ports and the top of the inner sidewalls of the unloading ports are all hinged with a tilting worktable; A categorized storage box is installed on the inner wall of the machine base, including several partitioned chambers, and several partitioned chambers correspond to the unloading ports of the machine base; The drive assembly is located on the outer wall of the machine base and can synchronously drive the tilting worktable to tilt downwards along the symmetrical axis. The driven component is located on the outer wall of the base and can be driven by the drive component; The suction assembly, which is located above the flipping worktable and consists of several units, includes a suction plate shell. The bottom of the suction plate shell is provided with several suction holes, which form the suction end. It can be driven by the driven assembly and rotated synchronously to the bottom of the suction plate shell, where the suction end corresponds one-to-one with the partition cavity of the sorting and storage box.

[0006] As a further description of the above technical solution: an X-axis displacement assembly is provided on the top of the base, and a Y-axis displacement assembly is connected to the power output end of the X-axis displacement assembly. A laser cutting head is provided on the power output end of the Y-axis displacement assembly.

[0007] As a further description of the above technical solution: the flipping worktable includes a flipping frame, the hinged end of the flipping frame is fixed with a hinge rod and is rotatably connected to the top of the machine base through the hinge rod, and the inner sidewall of the flipping frame is provided with a vacuum adsorption table.

[0008] As a further description of the above technical solution: the classification storage box includes a box shell, the top of the box shell is open, and a number of partition plates are installed on the inner side wall of the box shell, forming a number of partition cavities with the partition plates.

[0009] As a further description of the above technical solution: the drive assembly includes an electric motor, the power output end of the electric motor is connected to a worm gear, and a worm wheel meshes with the outer wall of the worm gear.

[0010] As a further description of the above technical solution: a spur gear A is coaxially arranged on the outer wall of the worm gear, a spur gear B with a diameter larger than that of the spur gear A meshes with the outer wall of the spur gear A, and a belt drive component A is coaxially arranged on the outer wall of the spur gear B and a spur gear C is connected through the belt drive component A.

[0011] As a further description of the above technical solution: the hinge rod ends of the two sets of symmetrically arranged flip frames are all meshed with a spur gear C, and the two spur gears C mesh with each other.

[0012] As a further description of the above technical solution: the suction assembly also includes an L-shaped frame rotatably connected to the outer wall of the base, and the suction plate shell is installed at the end of the L-shaped frame.

[0013] As a further description of the above technical solution: the top of the adsorption plate shell is connected to a flexible tube and a suction pump is connected through the flexible tube.

[0014] As a further description of the above technical solution: the driven component includes a rotating rod, one end of which is provided with a belt drive component B and is connected to the power output end of the drive component through the belt drive component B. A plurality of bevel gears A are installed on the outer side wall of the rotating rod, and bevel gears B are meshed on the outer side wall of the bevel gears A. The bevel gears B are installed at the bottom of the L-shaped frame.

[0015] In the above technical solution, the present invention provides the following beneficial effects: This invention enables the rotating worktable to rotate synchronously downwards along its axis of symmetry. Simultaneously, through the driven component, the suction component rotates until the bottom suction end of the suction plate corresponds one-to-one with the partition cavity of the sorting and storage box. The suction component first picks up the fabric from the top of the tilted rotating worktable, flattens it, and makes it roughly parallel to the ground. Then, the suction pump is turned off, allowing the fabric to float into the partition cavity of the corresponding sorting and storage box for sorting and storage. This allows the cut fabric to be quickly removed from the rotating worktable and stacked relatively flat after being dropped, solving the problem of poor sorting and unloading functionality in existing automatic fabric sorting devices.

[0019] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Please see Figures 1-7 The present invention provides a technical solution: including a base 1, with unloading ports symmetrically arranged on the top of the base 1 and a rotating worktable 5 hinged to the top of the inner sidewall of each unloading port; In another embodiment of the present invention, the flipping worktable 5 includes a flipping frame 501, the hinge end of the flipping frame 501 is fixed with a hinge rod and is rotatably connected to the top of the base 1 through the hinge rod, and a vacuum adsorption table 502 is provided on the inner side wall of the flipping frame 501.

[0021] The flip-up worktable 5 is located on top of the machine base 1 and is used to support and fix the fabric to be cut, and to perform the unloading action after the cutting is completed; The flipping frame 501 is a rigid frame structure. Its hinged sides are hinged to the unloading port of the machine base 1 through hinge rods, so that the flipping worktable 5 can rotate around the hinge rods.

[0022] The vacuum adsorption table 502 uses an existing product, preferably with a surface covered with a layer of high-temperature resistant and laser-abrasion resistant special felt or silicone pad. This protects the laser head and increases friction with the fabric. The table has numerous through holes inside, which connect to an external vacuum pump (not shown in the figure) independently of the suction pump 10. Before the cutting operation, the vacuum pump is started by an external power supply via an external switch. The negative pressure adsorbs the fabric onto the table, preventing displacement during cutting and ensuring cutting accuracy. After cutting, the vacuum adsorption is first turned off, releasing the main constraint force on the cut piece for easy subsequent flipping and unloading. In another embodiment of the present invention, preferably, an X-axis displacement component 2 is provided on the top of the base 1, the power output end of the X-axis displacement component 2 is connected to a Y-axis displacement component 3, and a laser cutting head 4 is provided on the power output end of the Y-axis displacement component 3.

[0023] The X-axis displacement assembly 2 and the Y-axis displacement assembly 3 have the same structure and both use existing products. Preferably, a linear guide rail is used as the guiding base, and a ball screw driven by a servo motor drives the slide on it to move horizontally, so that the laser cutting head 4 can reach any specified coordinate on the table plane.

[0024] The laser cutting head 4 is installed at the power output end of the Y-axis displacement assembly 3. It adopts existing products and integrates a focusing lens, gas nozzle and other components. It can emit a high-energy-density laser beam. The signal input end is connected to a control system. According to the CAD layout diagram pre-input by the control system, the movement trajectory of the X-axis displacement assembly 2 and the Y-axis displacement assembly 3 and the start, stop and power of the laser cutting head 4 are controlled, so as to melt and cut various complex shapes of fabric pieces. Existing technology is used here. The classification storage box 6 is set on the inner side wall of the machine base 1, and includes several partitioned cavities, with each partitioned cavity corresponding to the unloading port of the machine base 1; In another embodiment of the present invention, the classification storage box 6 includes a box shell 601 with an opening at the top. A plurality of partition plates 602 are installed on the inner side wall of the box shell 601, and a plurality of partition cavities are formed between the partition plates 602.

[0025] The top of the housing 601 is open to receive the cut pieces. Its interior is divided into multiple independent compartments by several partition plates 602. Each compartment is designed to hold one type or category of cut pieces. The height of the partition plates 602 must be sufficient to prevent the cut pieces from moving between compartments when they fall, and must not obstruct the unloading port that is exposed when the tilting worktable 5 is tilted down. It should also be noted that after the suction assembly 9 is rotated, the suction end at the bottom of the suction plate housing 901 corresponds one-to-one with the unloading port exposed when the tilting worktable 5 is tilted down. The categorized storage box 6 can adopt a pull-out design, making it easy for operators to retrieve the categorized cut pieces; Drive component 7 is located on the outer wall of the base 1 and can synchronously drive the tilting worktable 5 to tilt downward along the symmetrical axis; In another embodiment of the present invention, the drive assembly 7 includes a motor 701, the power output end of the motor 701 is connected to a worm 702, and a worm wheel 703 is engaged on the outer side wall of the worm 702.

[0026] In another embodiment of the present invention, a spur gear A704 is coaxially disposed on the outer side wall of the worm gear 703, and a spur gear B705 with a diameter larger than that of the spur gear A704 meshes with the outer side wall of the spur gear A704. A belt drive A706 is coaxially disposed on the outer side wall of the spur gear B705 and a spur gear C707 is connected through the belt drive A706.

[0027] In another embodiment of the present invention, the hinge rod ends of the two symmetrically arranged flip frames 501 are all meshed with spur gears C707, and the two spur gears C707 mesh with each other.

[0028] The motor 701 is used as the power source. The power is transmitted through the worm gear 702 and worm wheel 703. The worm gear 702 and worm wheel 703 are self-locking, so that the rotating worktable 5 can be self-locked before and after rotation, which can stably support the fabric. Then, the power is reduced and increased through the spur gears A704 and B705. The spur gear B705 transmits the power to two meshing spur gears C707 through the belt drive A706. These two spur gears C707 mesh with the ends of the hinge rods of the rotating worktables 5 on both sides, thereby synchronously driving the two rotating frames 501 to rotate downward. The driven component 8 is disposed on the outer wall of the base 1 and can be driven by the drive component 7; In another embodiment of the present invention, the driven component 8 includes a rotating rod 801. One end of the rotating rod 801 is provided with a belt drive component B802 and is connected to the power output end of the drive component 7 through the belt drive component B802. A plurality of bevel gears A803 are installed on the outer wall of the rotating rod 801. A bevel gear B804 meshes with the outer wall of the bevel gears A803. The bevel gears B804 are installed at the bottom of the L-shaped frame 903.

[0029] The suction assembly 9 is located above the flipping worktable 5 and there are several of them. It includes a suction plate shell 901. The bottom of the suction plate shell 901 is provided with several suction holes 902, which form the suction end. It can be driven by the driven assembly 7 through the driven assembly 8 and rotated synchronously until the suction end of the suction plate shell 901 corresponds one-to-one with the separation cavity of the classification storage box 6.

[0030] In another embodiment of the present invention, the suction assembly 9 further includes an L-shaped frame 903 rotatably connected to the outer wall of the base 1, and the suction plate shell 901 is installed at the end of the L-shaped frame 903.

[0031] In another embodiment of the present invention, the top of the adsorption plate shell 901 is connected to a flexible tube and a suction pump 10 is connected through the flexible tube to generate negative pressure suction.

[0032] The power of the drive assembly 7 is also transmitted to the rotating rod 801 of the driven assembly 8 via the belt drive component B802. The bevel gear A803 on the rotating rod 801 drives the bevel gear B804 to rotate, thereby causing the L-shaped frame 903 and the adsorption plate shell 901 at its end to rotate. It should be noted that during actual use, the transmission ratio needs to be adjusted so that when the suction assembly 9 rotates from a position that does not obstruct the cutting of the laser cutting head 4 to a position where the bottom suction end of the suction plate shell 901 corresponds one-to-one with the partition cavity of the sorting and storage box 6, the flipping worktable 5 flips down to expose the discharge port, which is sufficient to allow the fabric adsorbed by the bottom suction end of the suction plate shell 901 to float into the corresponding partition cavity of the sorting and storage box 6 from the discharge port exposed by the flipping worktable 5. Working Principle: This embodiment provides an automatic fabric sorting device for cutting. In use, the fabric is first laid on the vacuum adsorption table 502. An external power supply turns on the vacuum adsorption table 502 via an external switch, causing the fabric to be adsorbed onto it. The vacuum adsorption table 502 is an existing product; preferably, its surface is covered with a layer of high-temperature resistant and laser-abrasion resistant special felt or silicone pad, which protects the laser head and increases friction with the fabric. The table has numerous through-holes inside, connected to an external vacuum pump (not shown in the figure) independently of the suction pump 10. Before cutting, the external power supply starts the vacuum pump via an external switch, using negative pressure to adsorb the fabric onto the table, preventing displacement during cutting and ensuring cutting accuracy. After cutting, the vacuum adsorption is first turned off, releasing the main constraint force on the cut pieces for easy subsequent flipping and unloading. The X-axis displacement assembly 2, Y-axis displacement assembly 3 and laser cutting head 4 are turned on by an external power supply and cut according to the program. The X-axis displacement assembly 2 and the Y-axis displacement assembly 3 have the same structure and both use existing products. Preferably, a linear guide rail is used as the guiding base, and a ball screw driven by a servo motor drives the slide on it to move horizontally, so that the laser cutting head 4 can reach any specified coordinate on the table plane.

[0033] The laser cutting head 4 is installed at the power output end of the Y-axis displacement assembly 3. It adopts existing products and integrates a focusing lens, gas nozzle and other components. It can emit a high-energy-density laser beam. The signal input end is connected to a control system. According to the CAD layout diagram pre-input by the control system, the movement trajectory of the X-axis displacement assembly 2 and the Y-axis displacement assembly 3 and the start, stop and power of the laser cutting head 4 are controlled, so as to melt and cut various complex shapes of fabric pieces. Existing technology is used here. Once completed, turn off the vacuum adsorption platform 502 via an external switch to stop the fabric from being adsorbed. When the external power supply is turned on via an external switch, the drive assembly 7 and the suction pump 10 are activated. The two tilting worktables 5 tilt downwards synchronously. The motor 701 is the power source, and the power is transmitted through the worm gear 702 and worm wheel 703. The worm gear 702 and worm wheel 703 are self-locking, so that the tilting worktables 5 can be self-locked before and after rotation, which can stably support the fabric. Then, the power is reduced and increased through the spur gears A704 and B705. The spur gear B705 transmits the power to two meshing spur gears C707 through the belt drive A706. These two spur gears C707 mesh with the ends of the hinge rods of the two tilting worktables 5, thereby synchronously driving the two tilting frames 501 to tilt downwards. The power of the drive assembly 7 is also transmitted to the rotating rod 801 of the driven assembly 8 via the belt drive component B802. The bevel gear A803 on the rotating rod 801 drives the bevel gear B804 to rotate, thereby causing the L-shaped frame 903 and the adsorption plate shell 901 at its end to rotate. It should be noted that during actual use, the transmission ratio needs to be adjusted so that when the suction assembly 9 rotates from a position that does not obstruct the cutting of the laser cutting head 4 to a position where the bottom suction end of the suction plate shell 901 corresponds one-to-one with the separation cavity of the sorting and storage box 6, the flipping worktable 5 flips down to expose the discharge port, which is sufficient to allow the fabric adsorbed by the bottom suction end of the suction plate shell 901 to float into the corresponding separation cavity of the sorting and storage box 6 from the discharge port exposed by the flipping worktable 5.

[0034] The negative pressure at the bottom of several adsorption plates 901 will pick up the cut pieces in the corresponding areas one by one, which can effectively overcome the sticking of the cut pieces on the table caused by static electricity, melting or fiber entanglement, and can flatten the cut pieces. Then, the suction pump 10 is turned off, and the fabric adsorbed by the bottom adsorption end of the adsorption plate 901 floats into the corresponding partition cavity of the classification storage box 6 from the unloading port that is exposed under the flipped worktable 5.

[0035] The external power supply drives the drive component 7 to reverse through an external switch, and the flip worktable 5 is reset to a horizontal position to prepare for the next cut. The suction component 9 is reset and rotated to a position that does not obstruct the laser cutting head 4 from laser cutting (the X-axis displacement component 2, Y-axis displacement component 3, laser cutting head 4, vacuum adsorption table 502, motor 701 and suction pump 10 are all existing products and are all connected to the external power supply and external switch).

[0036] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
