[0001] This invention relates to the field of material storage and transfer technology, and in particular to a material turnover device. Background Technology

[0002] In the automotive assembly process, materials often need to be temporarily stored and transferred between adjacent workstations. Related technologies involve suspending materials in racks and using these racks to move materials between different workstations. However, this requires moving the racks themselves, and the racks' movement between workstations is not smooth enough, resulting in low material turnover efficiency. Summary of the Invention

After the operator at the loading station suspends the material using a hanging component, it is placed into the first chute of the first track component. Due to the gravity of the hanging component and the material, the hanging component causes the material to slide along a first direction. The first limiting part rotates and blocks the end of the first chute to prevent the sliding part of the hanging component from sliding out, thus storing multiple hanging components with suspended materials in the first chute of the first track component. The operator at the unloading station rotates the first limiting part to avoid the end of the first chute, thereby removing the hanging components and materials for assembly. After removing the material from the hanging component, the unloading process continues. The operator at the workstation places the unloaded hanging component into the second chute of the second track component. Due to the gravity of the hanging component, it slides along the second direction. The second limiting part rotates and blocks the end of the second chute to prevent the sliding part of the hanging component from sliding out. The worker at the loading station rotates the second limiting part to avoid the end of the second chute, removes the hanging component, and suspends the material.

[0020] In the description of this invention, it should be noted that terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0021] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of the present invention, not all embodiments.

[0022] In the automotive assembly process, materials often need to be temporarily stored and transferred between adjacent workstations. Related technologies involve suspending materials in racks and using these racks to move materials between different workstations. However, this requires moving the racks themselves, and the racks' movement between workstations is not smooth enough, resulting in low material turnover efficiency.

[0023] In related technologies, during the production of body-in-white parts, materials typically require temporary storage and sequential transfer between adjacent workstations. Existing material transfer methods often employ frame lifting devices, manual handling, ordinary material racks, AGVs (Automated Guided Vehicles), or powered conveyor lines. Manual handling and ordinary material racks suffer from high labor intensity, low efficiency, and poor workstation coordination. While AGVs, lifting devices, or chain conveyors can achieve automated transfer, they usually require motors, sensors, and control systems, resulting in high equipment costs, complex structures, and inconvenient maintenance. Therefore, a material handling device with a simple structure, requiring no power drive, capable of sequential material sliding by gravity, and able to perform limited-position storage of parts is needed.

[0024] Based on this, embodiments of the present invention provide a material handling device to solve the problems of high manual handling intensity, low storage efficiency of ordinary material racks, high cost of power conveying equipment, and inconvenience in empty hook retrieval during the transfer process between adjacent workstations in existing body-in-white assembly processes. Its inclined design of the first track component 200 and the second track component 300 allows materials to slide under their own weight after being hooked onto the hanging component 400. The device achieves piece-by-piece release, slow storage, and unloading control through the first limiting part 220 and the blocking part 500. It eliminates the need for motors, chains, and complex control systems, and has advantages such as simple structure, convenient operation, reliable operation, high storage efficiency, energy saving, and suitability for on-site layout.

[0025] refer to Figures 1 to 11 A material turnover device according to an embodiment of the present invention is described below, with specific examples illustrating the material turnover device.

[0026] Reference Figures 1 to 2 As shown, the material turnover device includes a support 100, a first track 200, a second track 300, a hanging component 400, a blocking component 500, a side limiting component 600, and an end limiting component 700.

[0027] Reference Figure 2 and Figure 3As shown, the support member 100 is formed by a frame structure. A loading station is located at the end of the support member 100 in a first direction, and a unloading station is located at the end of the support member 100 in a second direction. An internal conveying channel 110 extending along the first direction is provided inside the support member 100. The top inner wall of the conveying channel 110 is connected to a first track member 200, which extends along the first direction and gradually slopes downwards. A second track member 300 is connected to the outer wall of the support member 100, extending along the second direction and gradually slopes downwards.

[0028] Reference Figures 4 to 6 As shown, the first track component 200 is provided with a first slide groove portion 210 extending along a first direction. The bottom of the first slide groove portion 210 is through. The first slide groove portion 210 is through along the first direction. The bottom of the first slide groove portion 210 is provided with a plurality of first roller groups 211. The plurality of first roller groups 211 are arranged sequentially along the first direction. Each first roller group 211 is provided with two first rollers 212. The two first rollers 212 are arranged opposite each other in a direction perpendicular to the first direction. The axes of the two oppositely arranged first rollers 212 intersect at an inclination.

[0029] The first track member 200 has a first limiting part 220 and a first elastic part at its two ends respectively. The top of the end of the first slide groove 210 has a first opening. The first limiting part 220 is hinged to the top of the first slide groove 210. The first limiting part 220 can rotate around an axis perpendicular to the first direction so that the first limiting part 220 can rotate in the first opening. The side wall of the end of the first slide groove 210 facing outward is provided with a first stop. The first stop is located on the trajectory of the first limiting part 220 rotating outward in the first opening. The first stop restricts the degree of freedom of the first limiting part 220 to rotate outward in the first opening, so that the first limiting part 220 cannot rotate outward and can only rotate along the first opening into the first slide groove 210.

[0030] After rotating around its axis, the first limiting part 220 can cover the end of the first sliding groove part 210. The first elastic part is a torsion spring, which is disposed between the pivot of the first limiting part 220 and the bottom of the first sliding groove part 210. The elastic force of the first elastic part causes the first limiting part 220 to tend to move towards the first stop, thereby causing the first limiting part 220 to rotate towards the first stop and cover the end of the first sliding groove part 210. By pushing the first limiting part 220 inward against the elastic force of the first elastic part, the first limiting part 220 rotates into the first sliding groove part 210 in the first opening, thereby allowing the first limiting part 220 to avoid the first sliding groove part 210.

[0031] When the sliding part 410 of the hanging member 400 is disposed in the first slide groove 210, due to the cooperation of the first limiting part 220, the first slide groove 210, the first elastic part and the first stop, when the external force is removed, the first limiting part 220 can block the end of the first slide groove 210. The first limiting part 220 blocks the sliding part 410 from moving outward, thereby preventing the sliding part 410 of the hanging member 400 from sliding out of the end of the first slide groove 210.

[0032] Reference Figures 7 to 9 As shown, the second direction is opposite to the first direction. The second track member 300 is provided with a second slide groove 310 extending along the second direction. The bottom of the second slide groove 310 is through. The bottom of the second slide groove 310 is provided with a plurality of second roller groups 311. The plurality of second roller groups 311 are arranged sequentially along the second direction. Each second roller group 311 is provided with two second rollers 312. The two second rollers 312 are arranged opposite each other in a direction perpendicular to the second direction. The axes of the two oppositely arranged second rollers 312 intersect at an inclination.

[0033] The two ends of the second track member 300 are respectively provided with a second limiting part 320 and a second elastic part. The top of the end of the second slide groove 310 is provided with a second opening. The second limiting part 320 is hinged to the top of the second slide groove 310. The second limiting part 320 can rotate around an axis perpendicular to the second direction so that the second limiting part 320 can rotate in the second opening. The side wall of the end of the second slide groove 310 facing outward is provided with a second stop. The second stop is located on the trajectory of the second limiting part 320 rotating outward in the second opening. The second stop restricts the degree of freedom of the second limiting part 320 to rotate outward in the second opening, so that the second limiting part 320 cannot rotate outward and can only rotate along the second opening into the second slide groove 310.

[0034] After rotating around its axis, the second limiting part 320 can cover the end of the second sliding groove part 310. The second elastic part is a torsion spring, which is disposed between the pivot of the second limiting part 320 and the bottom of the second sliding groove part 310. The elastic force of the second elastic part causes the second limiting part 320 to tend to move towards the second stop, thereby causing the second limiting part 320 to rotate towards the second stop and cover the end of the second sliding groove part 310. By pushing the second limiting part 320 inward against the elastic force of the second elastic part, the second limiting part 320 rotates into the second sliding groove part 310 in the second opening, thereby allowing the second limiting part 320 to avoid the second sliding groove part 310.

[0035] When the sliding part 410 of the hanging member 400 is disposed in the second slide groove 310, due to the cooperation of the second limiting part 320, the second slide groove 310, the second elastic part and the second stop, when the external force is removed, the second limiting part 320 can block the end of the second slide groove 310. The second limiting part 320 blocks the sliding part 410 from moving outward, thereby preventing the sliding part 410 of the hanging member 400 from sliding out of the end of the second slide groove 310.

[0036] Reference Figure 10 As shown, the hanging component 400 includes a sliding part 410, a spacer part 420, and a hanging part. The sliding part 410 is cylindrical, and its axis is set along a first direction. The sliding part 410 has screw holes at its ends in the first and second directions, respectively. The spacer part 420 is a screw rod, and the two spacer parts 420 are screwed into the two screw holes, respectively. By rotating the spacer part 420, the distance of its outward protrusion can be changed, thereby adjusting the distance between two adjacent hanging components 400 in the first or second direction. The hanging part includes a first hook, a buckle ring, a second hook, and a hanging frame. The first hook is connected to the bottom of the sliding part 410, and the second hook is connected to the top of the hanging frame. The buckle ring is fitted onto the first hook and the second hook. There is a space for movement between the buckle ring and the first hook, and between the buckle ring and the second hook. After the hanging frame lifts the material 10, the hanging frame can move relative to the sliding part 410 to prevent the material 10 from interfering with the support member 100 and causing the sliding part 410 to get stuck.

[0037] Reference Figures 1 to 2 As shown, the sliding part 410 can be slidably disposed in the first chute 210 or the second chute 310. After the hanger 400 lifts the material 10, the hanger 400 and the material 10 can be placed into the conveying channel 110 of the support 100. Due to the combined effect of the weight of the hanger 400 and the weight of the material 10, the sliding part 410 in the first chute 210 slides along the first direction.

[0038] Since the second track member 300 is located outside the support member 100, the hanging member 400 can only be placed into the second slide groove 310 of the second track member 300 before the material 10 is hoisted. Due to the gravity of the hanging member 400, the sliding part 410 in the second slide groove 310 slides along the second direction.

[0039] Reference Figure 1 , Figure 2 and Figure 11 As shown, two blocking components 500 are respectively installed at the loading station and unloading station of the conveying channel 110.

[0040] Each blocking member 500 includes a rotating part 510, a blocking part 520, a counterweight part 530, an operating part 540, and an anti-rotation part 550.

[0041] The rotating part 510 is hinged to the support member 100. The rotating part 510 rotates about an axis parallel to the first direction. The bottom of the rotating part 510 is connected to the blocking part 520 on the side facing the first slide groove 210. The blocking part 520 extends towards the first slide groove 210, forming an "L" shape with the rotating part 510. The counterweight part 530 is connected to the bottom of the rotating part 510. The weight of the counterweight part 530 causes the rotating part 510 to drive the blocking part 520 to rotate to the first slide groove 210. The anti-rotation part 550 is connected to the support member 100 and is located on the trajectory of the rotating part 510 driving the blocking part 520 to move towards the first sliding groove 210. When the rotating part 510 contacts the anti-rotation part 550, the blocking part 520 is located below the first sliding groove 210, so that the blocking part 520 is located on the trajectory of the hanging member 400 moving along the first sliding groove 210. The blocking part 520 prevents the hanging member 400 from sliding along the first sliding groove 210.

[0042] The operating part 540 is a pull rope, and a pull ring is provided on the support member 100. The operating part 540 extends downward after passing through the pull ring. The operating part 540 is connected to the rotating part 510 on the side opposite to the first slide groove part 210. The operator pulls the operating part 540 to make the rotating part 510 rotate away from the first slide groove part 210 against the gravity of the counterweight part 530 and the gravity of the blocking part 520. This causes the rotating part 510 to disengage from the anti-rotation part 550 and the blocking part 520 to move from below the first slide groove part 210 to the outside of the first slide groove part 210. The hanging part 400, which was blocked by the blocking part 500, is released and moves in the first direction.

[0043] In this embodiment, two blocking members 500 are respectively disposed at both ends of the conveying channel 110 in the first direction and the second direction, and the distance between the two blocking members 500 is less than the distance between the two first limiting parts 220. When the hanging member 400 moves along the first direction in the first chute part 210, the hanging member 400 passes through the first limiting part 220 of the loading station, the blocking member 500 of the loading station, the blocking member 500 of the unloading station, and the first limiting part 220 of the unloading station in sequence.

[0044] In other words, referencing Figure 1As shown, the first operator places the hanging component 400 and the material 10 it is hoisting into the loading station. The hanging component 400 pushes the first limiting part 220 of the loading station to rotate in the first direction, causing the hanging component 400 to enter the first chute part 210. Then, the hanging component 400 is blocked by the blocking part 500 of the loading station. Then, the first operator pulls the corresponding operating part 540 to release the hanging component 400 and the material 10. The hanging component 400 continues to move along the first chute part 210 until it is blocked by the blocking part 500 of the unloading station. Then, the second operator pulls the corresponding operating part 540 to release the hanging component 400 and the material 10, causing the hanging component 400 to be stopped by the first limiting part 220 of the unloading station. Finally, the second operator pushes the first limiting part 220 of the unloading station to rotate in the second direction to open the first chute part 210, allowing the hanging component 400 and the material 10 to be removed from the unloading station.

[0045] Reference Figure 1 As shown, after the second operator removes the material 10 suspended by the hanging component 400, the second operator places the hanging component 400 into the second chute 310 from the unloading station. The hanging component 400 pushes the second limiting part 320 of the unloading station to rotate in the second direction, causing the hanging component 400 to enter the second chute 310. The hanging component 400 moves in the second direction in the second chute 310 until it is stopped by the second limiting part 320 of the loading station of the second chute 310. When the first operator needs to remove the hanging component 400, the first operator pushes the second limiting part 320 of the loading station to rotate in the first direction to open the second chute 310, allowing the hanging component 400 to be removed from the loading station. The first operator then hoists the material 10 onto the hanging component 400 and then puts the hanging component 400 back into the first chute 210.

[0046] Reference Figures 1 to 3 As shown, two side limiting members 600 are respectively connected to both sides of the support member 100. The two side limiting members 600 are located on both sides of the conveying channel 110, and the side limiting members 600 extend along the first direction. The side limiting members 600 are located outside the movement trajectory of the material 10 along the conveying channel 110, and the side limiting members 600 prevent the material 10 from moving in a direction perpendicular to the first direction.

[0047] Reference Figures 1 to 3 As shown, the end face limiting member 700 is rotatably connected to the support member 100. The end face limiting member 700 rotates around an axis parallel to the first direction. The end face limiting member 700 bends towards the conveying channel 110 at the ends of the loading station and the unloading station, respectively. When the end face limiting member 700 rotates around the axis, the two ends can rotate to both ends of the conveying channel 110, and the two ends can also rotate to a position offset from the conveying channel 110.

[0048] In this embodiment, a limiting plate is provided on the support member 100, and the limiting plate is located on the trajectory of the downward rotation of the end of the end face limiting member 700. When the end of the end face limiting member 700 contacts the limiting plate, the end of the end face limiting member 700 is parallel to the horizontal plane and the end of the end face limiting member 700 is located at the end of the conveying channel 110, so that the end face limiting member 700 prevents the material 100 in the conveying channel 110 from moving to the outside of the support member 100 along the first direction or the second direction. When it is necessary to pick up or put down the material 10, the operator needs to rotate the end of the end face limiting member 700 upward so that it is disengaged from the limiting plate and the end of the end face limiting member 700 is perpendicular to the horizontal plane, so that the end of the end face limiting member 700 is offset from the conveying channel 110, so as to facilitate the picking up or putting down of the material 10.

[0049] Specifically, the material turnover device includes a support component 100, a first track component 200, a second track component 300, a hanging component 400, and a blocking component 500.

[0050] Since the material 10 in this embodiment is a thin, irregularly shaped part related to the car door, it lacks a stable support surface when placed directly for transportation, which can easily cause shaking, bumping and scratches. Therefore, the non-powered hanging transportation and storage of the car door is completed by the cooperation of the support member 100, the first track member 200, the second track member 300, the hanging member 400 and the blocking member 500. The support member 100 serves as the overall load-bearing foundation. A loading station is located at the end of the support member 100 in the second direction, and a unloading station is located at the end of the support member 100 in the first direction. This station is used to install the first track member 200, the second track member 300, and the blocking member 500. Two side limiting members 600 and an end-face limiting member 700 are also provided to restrict the movement range of the assembly materials 10 related to the body-in-white during the hanging and sliding process, preventing excessive swaying of the materials 10. The first track member 200 and the second track member 300 are installed at an angle on the support member 100. At the loading station, the operator hangs the materials 10 onto the hanging member 400. The blocking member 500 at the loading station blocks and positions the hanging member 400, ensuring a stable and reliable material loading process. During loading, the end face limiting component 700 is rotated to open the conveying channel 110. The operator hangs the material 10 onto the hanging component 400, then closes the end face limiting component 700 and opens the blocking component 500 at the loading station. The material 10 and the hanging component 400 slide along the first track component 200 under their own gravity to the next storage position or unloading station, and are blocked by the blocking component 500 at the unloading station to prevent multiple materials from sliding simultaneously and colliding. During unloading, the end face limiting component 700 is rotated to open the conveying channel 110, and the operator at the unloading station removes the material 10 from the hanging component 400; the empty hanging component 400 is placed on the second track component 300, and the empty hanging component 400 slides back to the loading station by gravity. Through the above process, the entire workflow of loading, non-powered transfer, limiting storage, unloading, and return of the empty hanging component 400 for the body-in-white material 10 can be completed.

[0051] The support member 100 primarily provides a certain degree of inclination and load-bearing capacity for the first track member 200 and the second track member 300; it also provides load-bearing capacity for the two blocking members 500; the conveying channel 110 of the support member 100 provides installation space for the hanging and sliding of the material 10. The side limiting members 600 on both sides of the support member 100 are used to limit the lateral swaying of the material 10 during the sliding process; the end limiting members 700 limit the back-and-forth swaying of the material 10. Together, these two components prevent the body-in-white material 10 from colliding with the support member 100. Both the side limiting members 600 and the end limiting members 700 directly limit the material 10 itself, while the limiting of the hanging member 400 is achieved by the first limiting part 220 and the second limiting part 320.

[0052] The first track component 200 is used to support the hanging component 400 and the material 10, so that the material 10 slides along the first chute 210 under the action of gravity, realizing unpowered transfer and storage. The first limiting part 220 at both ends of the first chute 210 and the blocking part 500 at both ends of the support component 100 separate the control of the material 10 transfer stage and the empty hanging component 400 return stage.

[0053] The second track component 300 is used to support the unloaded hanging component 400 after the material 10 has been transferred, so that it can slide back to the loading station along the roller conveyor under the action of gravity, thus realizing the recycling of the hanging component 400.

[0054] The blocking component 500 at the loading station is used to block and release the hanging component 400, ensuring the stability of the material 10 during the hanging process and preventing the hanging component 400 from slipping prematurely before the material 10 is securely hung, thus enabling the sequential loading and release of the material 10 piece by piece. Specifically, the blocking component 500 at the loading station directly limits the hanging component 400, while the direct limitation of the material 10 is achieved by the side limiting component 600 on the support component 100.

[0055] The blocking component 500 at the unloading station is used to block and position the hanging component 400 and the material 10 at the end of the unloading process, so that the material 10 stops at the manual unloading position, realizing the unloading of one piece at a time and the return connection of the unloaded hanging component 400. Among them, the blocking component 500 at the unloading station directly limits the hanging component 400, and the direct limitation of the material 10 is achieved by the side limiting component 600 on the support component 100.

[0056] Hanging component 400 is used to carry material 10 and slide on the first track component 200 or the second track component 300.

[0057] The material turnover device includes a support component 100, a first track component 200, a second track component 300, a hanging component 400, and two blocking components 500, etc.

[0058] The support member 100 provides overall support, installation, and protective limiting. The conveying channel 110 of the support member 100 provides sufficient working space for the hanging and sliding of the material 10; the side limiting member 600 is used to limit the horizontal left and right swing range of the material 10 during the hanging and sliding process to prevent the material 10 from colliding with the support or adjacent materials 10; the end face limiting member 700 is used to limit the horizontal back and forth swing of the material 10; the four first mounting brackets of the support member 100 are distributed at intervals along the first direction, and the four first mounting brackets gradually decrease along the first direction and cooperate to form a 2-degree inclination angle to support the first track member 200; the four second mounting brackets of the support member 100 are distributed at intervals along the second direction, and the four second mounting brackets gradually decrease along the second direction and cooperate to form a 3-degree inclination angle to support the second track member 300.

[0059] The first track component 200 is installed on the four first mounting brackets of the support component 100 via four adjustable connectors to ensure the overall stable sliding of the hanging component 400 under gravity. During operation, the rotating end-face limiting component 700 is first rotated to a vertical position, and the material 10 is manually hung on the hanging component 400. Then, the end-face limiting component 700 is rotated to a horizontal position. The horizontal position is maintained by the limiting plate on the support component 100 supporting the end of the end-face limiting component 700, thus limiting the material 10. The operator pulls the operating part 540 of the loading station, causing the rotating part 510 to rotate 90 degrees, releasing the hanging component 400 and the material 10. After the operator releases the operating part 540, the rotating part 510 and the counterweight part 530 reset under gravity and re-enter the trajectory of the next hanging component 400, blocking the movement of the hanging component 400 and the material 10, thus achieving piece-by-piece control. After being released, the hanging component 400 and the material 10 slide along the first track component 200 under their own weight until they are stopped by the blocking component 500 of the unloading station and the end face limiting component 700 on the support component 100, thus achieving the functions of non-powered transfer, sequential storage and single-piece conveying of the body-in-white material 10.

[0060] After the operator finishes unloading, they pull the operating part 540 of the unloading station, causing the rotating part 510 to rotate 90 degrees. The hanging part 400 continues to slide and stops between the first limiting part 220 and the blocking part 500 of the unloading station. The operator pushes the first limiting part 220 into the interior of the first chute part 210. After the hanging part 400 separates from the material 10, the operator pushes the second limiting part 320 in the second track part 300 to hang the unloaded hanging part 400 into the second chute part 310, allowing it to flow back to the loading station by gravity. The operator at the loading station pushes the second limiting part 320 to remove the hanging part 400 and pushes the first limiting part 220 of the first track part 200 to hang the unloaded hanging part 400 into the first chute part 210, thus entering the next cycle.

[0061] The side limiting member 600 is slidably connected to the support member 100, allowing the relative distance between the two side limiting members 600 to be adjusted in the horizontal direction. The side limiting member 600 adopts a pressure plate clamping structure to connect with the support member 100, supporting stepless position adjustment, and can adapt to materials 10 of various widths, accurately matching the optimal limiting state of the material 10 in the left and right directions. The end limiting member 700 limits the material 10 in the front and back directions, preventing the material 10 from shifting due to inertia after the hanging member 400 stops. The ends of the side limiting member 600 and the end limiting member 700, as well as the hanging part of the hanging member 400, are all provided with an external rubber layer, which can buffer impact and protect the material 10.

[0062] The first track component 200 is mounted at an angle on the support component 100 via four adjustable connectors. These connectors allow for minute adjustments to the installation height and tilt angle of the first track component 200, ensuring stable sliding of the hanging component 400 and the material 10 parts under gravity, thus achieving a non-powered transport function. The top plate of the first chute 210 is made of transparent acrylic, facilitating observation of the fault location and precise disassembly and repair of the first chute 210 in case of internal malfunction. The first rollers 212 inside the first chute 210 are arranged in an inverted "V" shape, with an 80-degree internal angle between the axes of two rollers 212. Each roller 212 makes point contact with the sliding part 410, thereby reducing friction. The first chute 210 is provided with first limiting parts 220 at both ends. Without human intervention, it only allows entry but not exit. The first limiting part 220 must be pushed manually to remove the hanging part 400. The first limiting part 220 and the blocking part 500 of the loading station cooperate to realize the placement of the hanging part 400 piece by piece. The first limiting part 220 and the blocking part 500 of the unloading station cooperate to realize the picking and delivery of the hanging part 400 piece by piece.

[0063] The second track component 300 is mounted at an angle on the support component 100 via four adjustable connectors. These connectors allow for minute adjustments to the installation height and tilt angle of the second track component 300. The top plate of the second slide section 310 is made of transparent acrylic material, facilitating observation of fault points and precise disassembly and repair. Inside the second slide section 310, the second rollers 312 are arranged in an inverted "V" shape, with an 80-degree internal angle between the axes of two second rollers 312. Each second roller 312 makes point contact with the sliding part 410, thereby reducing friction. Second limiting parts 320 are located at both ends of the second slide section 310, allowing only entry but not exit without human intervention. The hanging component 400 can only be removed by manually pushing the second limiting parts 320. This component reduces the workload of manually handling the hanging component 400 and allows for its reuse.

[0064] The support member 100 is equipped with two lifting eye bolts, which serve to steer the operating part 540 of the blocking member 500 at the loading station. The counterweight 530 can be adjusted according to actual conditions. The blocking member 500 at the loading station enables the material 10 to be loaded, released, and stored sequentially, preventing the material 10 from slipping prematurely if it is not securely attached, and preventing multiple materials 10 from slipping simultaneously.

[0065] The support member 100 is equipped with two lifting eye bolts, which serve to steer the operating part 540 of the blocking member 500 at the unloading station. The counterweight 530 can be adjusted according to actual conditions. The blocking member 500 at the unloading station realizes terminal stopping, unloading positioning, and empty hanging member 400 return release, and separates the material transfer stage and the empty hanging member 400 return stage for control.

[0066] The spacer portions 420 at both ends of the hanging member 400 provide end-limiting. By adjusting the screw-in distance of the spacer portions 420, the spacing between the two hanging members 400 can be flexibly set to achieve fixed-distance storage. The spacer portions 420 are used to adjust the spacing to compensate for the inertial displacement of the material after it is stopped by the blocking member 500 due to gravity sliding, preventing the material 10 from being damaged by collision. The hanging part and the sliding part 410 of the hanging member 400 are flexibly connected by a carabiner. When the hanging member 400 carries the material 10 and slides along the first track member 200, and is stopped momentarily by the blocking member 500 at the unloading station, the carabiner of the hanging member 400 acts as a buffer to avoid relative friction damage between the material 10 and the hanging part. The shape of the hanging part is designed according to the load data of the material 10 to ensure that the center of gravity of the material 10 and the hanging member 400 does not shift after the material 10 is hung, and the material 10 is in a vertical state. A rubber tube is inserted into the working surface of the hanging part that contacts the material 10 for isolation. The rubber tube is replaceable.

[0067] The first chute section 210 and the second chute section 310 can be replaced with roller guide rails, slide rails, chutes, or low-friction guide rails; the hanging part of the hanging component 400 can be replaced with a single hook, double hook, hook with rollers, or hook with positioning groove, depending on the structure of the material 10; the blocking component 500 can adopt a rope counterweight structure, or a spring return type limit, handle-operated type limit, foot pedal type limit, cylinder limit, or electromagnetic limit structure; the second track component 300 can be set on the side, bottom, or top of the support component 100, and its return direction and tilt angle can be adjusted according to the site space. The above alternative structures can all achieve the purpose of non-powered transfer of body-in-white material 10, limited storage, piece-by-piece unloading, and return of unloaded hanging component 400.

[0068] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate; that is, they may be located in one place or distributed across multiple network units. Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs.
