Description

Technical Field

[0001] This invention relates to the field of intelligent overhead conveying systems, and more specifically, to an intelligent overhead conveying system for embroidered fabrics. Background Technology

[0002] In modern embroidery production processes, intelligent and automated material conveying is a key link to ensure efficient production. Among them, rolls of fabric, as the core raw material for embroidery production, rely heavily on intelligent overhead conveying systems for their flow from storage areas to various processing steps (such as unrolling, cutting, and embroidery). With its advantages such as saving ground space and enabling flexible docking of multiple workstations, the intelligent overhead conveying system has become an indispensable piece of equipment in large-scale embroidery production. It undertakes the important task of rapidly and orderly transferring rolls of fabric between different production stages, directly affecting the production rhythm and efficiency of the entire embroidery production line. In the existing technology, when the intelligent overhead conveyor system is near the working area, the roll of fabric needs to be placed manually on the carrier module without stopping the machine. This process not only requires precise alignment to ensure the stability of the fabric as much as possible, but also consumes a lot of physical strength. It is difficult to operate the intelligent overhead conveyor system without stopping the machine. Currently, it is relatively easy to manually hang smaller rolls of fabric on the carrier module, but it is difficult to manually hang larger rolls of fabric on the carrier module. More importantly, the stability of the rolled fabric on the pallet is difficult to guarantee. The mechanical vibration generated during the operation of the overhead conveyor system continuously acts on the support module. Even if the fabric is initially placed in a relatively neat manner, it will gradually shift axially or radially during vibration. As the conveying distance increases, the offset accumulates, causing the center of gravity of the fabric to deviate from the center of the support module. When the center of gravity offset exceeds a critical value, the fabric risks falling off the support module. Therefore, an intelligent overhead conveyor system for embroidered fabric is proposed to solve the above problems. Summary of the Invention

[0003] To solve the above-mentioned technical problems, an intelligent hanging conveying system for embroidered fabric is provided. This technical solution solves the problems mentioned in the background technology.

[0004] To achieve the above objectives, the present invention can be implemented using the following technical solutions: This invention provides an intelligent hanging conveying system for embroidered fabric, including a guide rail and a lifting frame. A chain is movably connected to the inner wall of the guide rail. The lifting frame is located below the guide rail. Multiple trays are arranged sequentially from bottom to top inside the lifting frame. The lifting frame is equipped with a lifting component that drives the multiple trays to rise. Clamping components are installed on the outer wall of the trays. A winch is mounted on the bottom outer wall of the chain via a connector, and a hook is provided below the winch for suspending the pallet. The lifting assembly includes a rotating shaft, a tilting limit block, and a cylinder. Multiple rotating shafts are linearly arrayed and fixedly connected to the inner walls of both sides of the lifting frame from bottom to top. Every two tilting limit blocks are rotatably connected to the outer wall of the rotating shaft. The tray is located above the ends of the multiple tilting limit blocks. Two cylinders are fixedly installed on the bottom inner wall of the lifting frame, and their output ends are fixedly connected to a top plate. The top plate abuts against the bottommost tray.

[0005] Furthermore, multiple limiting rods are fixedly connected in a linear array at equal intervals from bottom to top on both sides of the inner wall of the lifting frame. The limiting rods are located above the ends of the two flipping limiting blocks facing the inner wall of the lifting frame and abut against the upper ends of the flipping limiting blocks.

[0006] Furthermore, two top frames are fixedly connected to the top outer wall of the tray, and a lifting rod is fixedly connected to the opposite outer wall of the two top frames. The lifting rod is engaged with a hook, and the height of the two top frames is equal to the distance between the two trays.

[0007] Furthermore, the bottom outer wall of the tray is fixedly connected with multiple feet, which are evenly distributed at the four corners of the tray at equal intervals.

[0008] Furthermore, the clamping assembly includes arc-shaped grippers, arc-shaped pads, movable columns, and a return spring. Multiple arc-shaped grippers are hinged inside the tray, with each pair of arc-shaped grippers arranged symmetrically. Two movable columns are slidably connected to the outer wall of the tray, with their bottom ends passing through the tray and their top ends fixedly connected to the arc-shaped pads. Arc-shaped connecting rods are hinged to the outer walls of the bottom two ends of the flipping limit block, and the end of the arc-shaped connecting rod away from the arc-shaped pads is hinged to the inner wall of the arc-shaped grippers.

[0009] Furthermore, the return spring is sleeved on the outer wall of the movable column, the top end of the return spring abuts against the bottom outer wall of the arc-shaped pad, and its bottom end abuts against the top outer wall of the tray. The bottom end of the movable column is on the same horizontal plane as multiple feet.

[0010] Furthermore, multiple mounting brackets are fixedly connected to the top outer wall of the guide rail, which are used to fix the guide rail to the wall. A driving device is installed on the top outer wall of the guide rail, which is used to drive the chain to run inside the guide rail.

[0011] As described above, the features and advantages of the intelligent hanging conveyor system for embroidered fabric in this invention are: This system reduces manual intervention in the placement and fixing of rolled fabrics by using automated lifting and clamping components. It eliminates the tedious operation of precise manual alignment and solves the problem of suspending materials without stopping the intelligent overhead conveyor system.

[0012] This system uses an external control system to drive the winch and drive unit to work together. The hook can automatically and accurately connect to the pallet and complete the connection, which greatly shortens the connection time. The mechanical connection is much more stable than manual operation, which effectively reduces failures caused by loose connection, significantly improves the efficiency of the material feeding and connection process, ensures the smooth production rhythm, and solves the problem of inconvenience of manually hanging large rolls of fabric in existing intelligent overhead conveyor systems.

[0013] The clamping components of this system utilize the fabric's own weight to achieve self-clamping. The arc-shaped grippers fit tightly against both ends of the fabric, and the structural design of the pallet base and movable column effectively resists mechanical vibration during the conveying process, preventing the fabric from shifting axially or radially. Even during long-distance conveying, it ensures the stability of the fabric's center of gravity, preventing it from falling due to the center of gravity shifting beyond the critical value. This reduces fabric loss and the risk of equipment damage, ensuring the safety and reliability of the conveying process. Attached Figure Description

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

[0017] See Figures 1-6 As shown, an embodiment of the present invention is provided, and an intelligent hanging conveying system for embroidered fabric will be described in detail below: See Figure 1 and 2 As shown, an intelligent suspended conveying system for embroidered fabric is disclosed. The main frame of the system consists of a guide rail 1 and a lifting frame 2. The guide rail 1 serves as the path carrier for suspended conveying, and the chain 11 movably connected to its inner wall provides the power transmission basis for the moving parts. The chain 11 can circulate along the extension direction of the guide rail 1. The lifting frame 2 serves as the lifting device for the pallet 26 and is set directly below the guide rail 1. The two form a vertical correspondence, which facilitates the subsequent suspension operation of the pallet 26 by the hook 16.

[0018] Reference Figure 3 and Figure 4 As shown, the multiple trays 26 inside the lifting frame 2 are arranged in a stacked layout, arranged sequentially from bottom to top. Each tray 26 can carry rolls of embroidered fabric. The lifting assembly is the core structure for raising the trays 26. It includes a rotating shaft 21, a flipping limit block 23, and a cylinder 24 working together: multiple rotating shafts 21 are fixed in a linear array at equal intervals on both sides of the inner wall of the lifting frame 2, providing rotational support for the flipping limit block 23; every two flipping limit blocks 23 are symmetrically rotated and connected to the same rotating shaft 21, and their ends jointly support the upper trays 26; the cylinder 24 is installed at the bottom of the lifting frame 2, and the top plate 25 connected to its output end directly contacts the lowermost tray 26. The extension and retraction of the cylinder 24 pushes the trays 26 upward, thereby driving the upper trays 26 to rise sequentially. It is worth noting that the bottom of the flipping limit block 23 is inclined upward, so that when the trays 26 move upward, the inclined surface of the bottom of the flipping limit block 23 pushes the flipping limit block 23 to flip.

[0019] Reference Figure 2 and Figure 3 As shown, the winch 15 is installed at the bottom of the chain 11 via the connector 14. The winch 15 is the core component for lifting and lowering the hook 16. Its working principle is based on mechanical transmission and force transmission, as detailed below: Power input and transmission: The winch 15 is equipped with a motor (as a power source) and a reduction gear set. After the motor starts, the high-speed rotational motion output is reduced by the reduction gear set, which reduces the speed and increases the torque, providing sufficient power for the winding and unwinding of the rope. Rope winding mechanism: The decelerated power is transmitted to the drum of the winch 15. The drum is fixedly connected to the output shaft of the reduction gear set. When the drum rotates forward, the rope (usually a high-strength steel wire rope) wound on the drum is wound up, and the hook 16 connected to the other end of the rope is lifted upward by the pull of the rope. When the drum rotates in reverse, the rope is released, and the hook 16 descends downward under the weight of itself and the suspended pallet 26. Braking device coordination: The winch 15 has a built-in braking device (such as an electromagnetic brake or a mechanical brake). When the motor stops working, the braking device automatically locks the drum to prevent it from rotating unexpectedly due to gravity or other factors, ensuring that the hook 16 and the suspended pallet 26 can stay stably at the required height and avoid falling. When the hook 16 is engaged with the lifting rod 29 on the pallet 26, the pallet 26 can be lifted from the lifting frame 2 and transported to the designated position along the guide rail 1 with the chain 11. It is worth noting that, in conventional designs in this field, to ensure a continuous and stable power supply to the winch 15 as it moves along the guide rail 1 with the chain 11, the power supply connection cable must be designed to be both responsive and avoid tangling. A specific solution is as follows: A sliding contact line (composed of copper or aluminum conductive rails, wrapped with an insulating layer) is installed parallel to the outside of the guide rail 1 as a carrier for mobile power supply. A current collector is installed on the winch 15. The conductive brush head of the current collector is in close contact with the sliding contact line and can slide along the sliding contact line as the winch 15 moves. One end of the power supply cable is connected to an external power source, and the other end is connected to the input end of the sliding contact line. The current collector is connected to the motor of the winch 15 through internal wires, thus forming a complete power supply circuit. When the winch 15 moves with the chain 11, the current collector slides on the sliding contact line, continuously supplying power to the winch 15. This is existing technology and will not be described in detail further. (Refer to...) Figure 5 As shown, hook 16 should be fixedly connected to the hanging plate above it to ensure that hook 16 does not sway.

[0020] Furthermore, the cooperation relationship between the inner limit rod 22 and the flipping limit block 23 of the lifting frame 2 is defined to enhance the stability of the pallet 26 lifting process. Multiple limit rods 22 are fixed in a linear array on both sides of the inner wall of the lifting frame 2 at the same spacing as the rotating shaft 21. Their positions are above the end of the flipping limit block 23 facing the inner wall of the lifting frame 2 and abut against the upper end of the flipping limit block 23. A torsion spring is provided between the inside of the flipping limit block 23 and the outer wall of the rotating shaft 21. When the tray 26 is pushed upward, the flipping limit block 23 flips upward around the pivot 21. At this time, the torsion spring deforms and generates elastic force, which helps the flipping limit block 23 to return to its original position. After the tray 26 has finished moving upward and pushing the flipping limit block 23, the flipping limit block 23 has the power to return to its original position. At the same time, the limiting rod 22 limits the downward flipping angle of the flipping limit block 23, preventing it from over-flipping and losing its ability to support the upper tray 26. Furthermore, under the action of the weight of the tray 26, the end of the flipping limit block 23 always abuts against the limiting rod 22, forming a stable support structure, ensuring that each tray 26 can be accurately positioned at the corresponding height during the upward process, avoiding swaying or falling.

[0021] Furthermore, referring to Figure 5 As shown, the connection structure between the pallet 26 and the hook 16 is clearly defined. The two top frames 27 fixed to the outer wall of the top of the pallet 26 are symmetrically distributed. There are two lifting rods 29 connected to the outer wall of the pallet 26, which are designed to be one high and one low. As the hooking part of the hook 16, the diameter or width of the lifting rod 29 is adapted to the hook groove of the hook 16 to ensure that the two can be stably engaged and prevent them from falling off during the suspension and transportation process. It should be noted that an annular groove should be opened on the outer wall of the lifting rod 29 located inside the hook groove of the hook 16 so that the lifting rod 29 can be engaged with the hook 16 when it is hooked, thus preventing the lifting rod 29 from sliding left and right.

[0022] Reference Figure 3 As shown, the height of the two top frames 27 is equal to the distance between the two pallets 26. This design ensures that when multiple pallets 26 are stacked in the lifting frame 2, the bottom feet 28 of the upper pallet 26 will not interfere with the top frame 27 of the lower pallet 26. At the same time, it ensures that the hook 16 has enough operating space when hooking the lifting rod 29 of any layer of pallet 26, without the need to adjust the position of the hook 16. In addition, multiple layers of pallets 26 can be lifted and pushed against each other by the top frames 27.

[0023] Furthermore, the structure and layout of the bottom feet 28 of the pallet 26 are described. Their function is to enhance the stability of the pallet 26 when it is placed. Multiple feet 28 are made of rigid material and are evenly distributed at the four corners of the pallet 26 to form a stable support surface. Furthermore, referring to Figure 5 and Figure 6 As shown, the structure and working method of the clamping component are described in detail. Its function is to fix the roll of fabric on the tray 26. The multiple arc-shaped claws 31 in the clamping component adopt a symmetrical layout and are hinged to the inner edge of the tray 26. Their arc-shaped contours are adapted to the outer circumference of the multiple rolls of fabric, and can fit the fabric surface to achieve stable clamping of the multiple rolls of fabric. The movable column 33 passes through the outer wall of the tray 26 and slides thereto, while its bottom end extends to the bottom of the tray 26. The two ends of the bottom of the arc-shaped pad 32 are hinged to the inner wall of the arc-shaped gripper 31 through the arc-shaped connecting rod 35 to form a linkage structure. When the rolled-up fabric is placed on the two arc-shaped pads 32, the weight of the fabric itself will exert downward pressure on the arc-shaped pads 32. Under this pressure, the arc-shaped pads 32 drive the movable column 33, which is fixedly connected to it, to slide downward along the outer wall of the tray 26. At this time, the return spring 34 sleeved on the outer wall of the movable column 33 is deformed by the compression of the arc-shaped pad 32, thereby generating upward elastic potential energy to store power for subsequent reset. At the same time, as the arc-shaped pad 32 moves downward, the arc-shaped connecting rods 35 hinged at both ends of its bottom will pull the arc-shaped grippers 31 downward. Since the arc-shaped grippers 31 are hinged inside the tray 26, under the traction of the arc-shaped connecting rods 35, the two symmetrically arranged arc-shaped grippers 31 will rotate relative to each other around their respective hinge points (i.e., move closer to each other). As the arc-shaped grippers 31 gradually close, their arc-shaped inner walls will tightly fit the two ends of the rolled fabric, thereby achieving automatic clamping of the fabric and effectively preventing the fabric from shifting or slipping on the tray 26.

[0024] Furthermore, the installation method of the return spring 34 and the positional relationship of the movable column 33 are supplemented. The return spring 34 is sleeved on the outer wall of the movable column 33 and is located between the arc-shaped pad 32 and the top outer wall of the tray 26. In its natural state, it is in a compressed state, providing an upward elastic force to the arc-shaped pad 32. When the arc-shaped pad 32 moves downward under the pressure from above, the return spring 34 is further compressed and stores elastic potential energy. When the pressure disappears, the return spring 34 releases the elastic potential energy, pushing the arc-shaped pad 32 to return to its original position. This, in turn, drives the arc-shaped gripper 31 to rotate outward through the arc-shaped connecting rod 35, releasing the grip on the fabric. This initial state setting is to coordinate with the reset action of the gripping components when the tray 26 is placed on the processing table. The specific process is as follows: When the rolled-up fabric is self-clamped by the clamping assembly, under the action of the fabric's gravity, the arc-shaped pad 32 drives the movable column 33 to slide downward. At this time, the bottom of the movable column 33 will be lower than the bottom of the multiple feet 28 and will no longer be on the same horizontal plane. When the tray 26 carrying the fabric is conveyed to the worktable and placed, the bottom of the movable column 33 will first contact the worktable because it is at a lower position. As the tray 26 continues to be placed downward, the worktable will exert an upward pushing force on the movable column 33, forcing the movable column 33 to slide upward. During the upward movement of the movable column 33, it will drive the arc-shaped pad 32 to move upward synchronously. At this time, the compressed return spring 34 will further release its elastic potential energy to help the arc-shaped pad 32 return to its original position. At the same time, the arc-shaped connecting rod 35 at the bottom of the arc-shaped pad 32 will pull the arc-shaped gripper 31 to rotate in the opposite direction (away from each other), thereby releasing the grip on the fabric. The arc-shaped pad 32 will also push the fabric upward to facilitate the subsequent processing steps to retrieve the fabric. When the tray 26 is completely placed and stable, and the multiple feet 28 are in contact with the table surface, the movable column 33 rises to its initial position under the pushing force of the table surface. Its bottom end is once again at the same level as the multiple feet 28, and it no longer rises. The clamping assembly returns to its initial state, waiting for the next cloth placement and clamping operation. This design utilizes the action of placing the tray 26 on the table to automatically trigger the clamping component to reset, without the need for additional operation, achieving seamless connection between fabric feeding and processing, and improving the automation level of the overall production process.

[0025] Furthermore, referring to Figure 2 As shown, the installation and fixing method and power source of the guide rail 1 are explained. Multiple mounting brackets 13 on the top outer wall of the guide rail 1 are fixed to the workshop wall or ceiling by bolts and other connecting parts to ensure that the guide rail 1 remains stable when bearing the weight of components such as chain 11, winch 15, hook 16 and pallet 26, and will not shake or shift. This is the prior art and will not be described in detail here. The drive unit 12, mounted on the top outer wall of the guide rail 1, typically employs a transmission structure consisting of a motor, a synchronous pulley, and a synchronous belt to drive the chain 11. Its specific working principle is as follows: The motor serves as the power source for the drive device 12. After being powered on, the output shaft of the motor rotates, converting electrical energy into mechanical energy to provide initial power for the entire transmission system. A synchronous pulley (driving synchronous pulley) is fixedly installed on the output shaft of the motor, while another synchronous pulley (driven synchronous pulley) is fixedly installed at one end of the transmission shaft. The driving synchronous pulley and the driven synchronous pulley are driven by a synchronous belt. The toothed structure on the inner side of the synchronous belt meshes with the teeth of the two synchronous pulleys to ensure that there is no relative slippage during transmission. When the output shaft of the motor drives the driving synchronous pulley to rotate, the driving synchronous pulley drives the driven synchronous pulley to rotate synchronously through the tooth transmission of the synchronous belt, thereby causing the transmission shaft to rotate together with the driven synchronous pulley. This is existing technology and will not be described in detail here. A sprocket is fixedly installed at the other end of the drive shaft. The sprocket meshes with the chain 11 in the guide rail 1. When the drive shaft rotates under the drive of the driven synchronous wheel, the sprocket rotates with the drive shaft. The teeth of the sprocket are embedded between the links of the chain 11. Through the interaction between the teeth and the links, the rotational motion is converted into the linear motion (circular motion) of the chain 11. Driven by the sprocket, the chain 11 circulates along the inner wall of the guide rail 1. Since the winch 15 is installed on the bottom outer wall of the chain 11 through the connector 14, the movement of the chain 11 drives the winch 15, the hook 16, and the tray 26 suspended by the hook 16 to move together along the guide rail 1, thereby realizing the conveying of the rolled fabric. It is worth noting that in this invention, the drive device 12 (motor), the winch 15 (built-in motor), and other electrical equipment are all electrically connected to an external control system (such as a PLC control cabinet or industrial computer) through cables to form a unified automated control network, which is an existing technology and will not be elaborated further.
