Description

Technical Field

[0001] This invention belongs to the field of suspended conveying technology, and more specifically, relates to a circulating suspended conveying device. Background Technology

[0002] In the automobile production process, automobile parts need to be transported back and forth in the workshop for processing. Among them, overhead conveyor is a common method and is widely used in the assembly lines of various industrial sectors to transport workpieces between processes, complete various technological processes, and realize the comprehensive mechanization of conveying and process operations.

[0003] There are many types of overhead conveyor equipment currently available. In workshop production, the conveying mechanisms are mainly divided into the following categories: 1. Roller-type unidirectional conveyor mechanism: This type of mechanism can only convey in one direction, and automotive parts are prone to jamming, resulting in a high on-site failure rate; 2. Hanging conveyor mechanism: This type of mechanism can convey in both directions, but requires workers to manually switch the positioning mechanism of automotive parts, resulting in high labor intensity and long loading time; 3. Circular track motor conveyor mechanism: This type of mechanism uses motor conveying, which has high manufacturing costs, cannot achieve manual loading and unloading at any time, and has asynchronous loading and unloading at both ends.

[0004] Publication No. CN 117302880 A, Publication Date: December 29, 2023, Patent Title: A Suspended Conveying Device. This invention provides a suspended conveying device, including a conveying track and multiple conveying trolleys mounted on the track. Each conveying trolley includes a body, a front shovel hinged to the front end of the body, and a rear shovel fixedly connected to the rear end of the body. The rear shovel has multiple rear shovel pins arranged front-to-back, horizontally along the left-right direction of the conveying trolley. The front shovel includes a first toothed disc with multiple meshing teeth on its outer edge. When two adjacent conveying trolleys come into contact, the meshing teeth of the first toothed disc engage with the rear shovel pins. When the front shovel flips backward, it triggers a braking device inside the conveying trolley. In this technical solution, the brake triggering device is designed with pins meshing with the toothed disc, maintaining a stable flipping torque during the disc's flipping process, thus ensuring reliable braking and effectively preventing collisions between adjacent conveying trolleys caused by the brake's failure to activate. However, this suspended conveying device has high manufacturing costs and low conveying efficiency. Summary of the Invention

[0030] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0031] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0032] The present invention provides a circulating suspended conveyor device, such as... Figures 1 to 6 As shown, the device includes a support frame 100, a hanging mechanism 200, a track assembly 300, a blocking mechanism 400, and a hook assembly 500. This circulating suspended conveyor includes a support frame 100, a track assembly 300 connected to the support frame 100 via a telescopically adjustable hanging mechanism 200, a blocking mechanism 400 on the track assembly 300 to block the conveying of workpieces, and a hook assembly 500 on the track assembly 300 to hook the workpieces.

[0033] In this invention, such as Figure 1 As shown, the support frame 100 is a welded portal frame, serving as the support for the suspended ceiling. The support frame 100 includes vertical support columns arranged in two parallel, spaced-apart rows. Each row has multiple support columns arranged at intervals. Two opposing support columns form a set of support columns. The lower ends of the support columns are supported on the workshop floor, and the upper ends of each set of support columns are connected by support beams. Support longitudinal beams are provided on the support beams. To accommodate the arrangement of the suspension mechanism 200, the support frame includes multiple spaced-apart support longitudinal beams, to which the suspension mechanism 200 is supported and connected.

[0034] In this invention, such as Figure 1 , 2 As shown, the suspension mechanism 200 is suspended on top of the support frame 100 and connected to the support longitudinal beam. The suspension mechanism 200 serves as a longitudinal connector connecting the support frame 100 and the track assembly 300. In one embodiment of the present invention, two sets of symmetrically arranged track assemblies 300 are provided on both sides of the support frame, saving space and improving conveying efficiency.

[0035] In this invention, such as Figure 3 As shown, the suspension mechanism 200 includes a suspension base 210, which is mounted on a supporting longitudinal beam. A movable tie rod 220 is hinged to the lower part of the suspension base 210 via a hinge shaft. A connecting block 230 is connected to the lower end of the movable tie rod 220, and the connecting block 230 supports and connects the track assembly 300. The suspension base 210 includes an upper connecting plate and a lower connecting plate respectively arranged above and below the supporting longitudinal beam. The four corners of the upper and lower connecting plates are connected by bolts. The connecting block 230 can be welded to the upper part of the track assembly.

[0036] In this invention, such as Figure 1 , 2 As shown in Figure 3, the track assembly 300 is connected to the bottom of the suspension mechanism 200. The track assembly 300 is a magnetic track. Figure 4 As shown, the track assembly 300 includes a track housing 310, a winding post 320 disposed within the track housing 310, and an electromagnetic coil 330 wound around the outside of the winding post 320. The electromagnetic coil 330 generates magnetism when energized, enabling the track assembly 300 to function as an electromagnetic track. The track housing 310, as shown, is a closed loop-shaped structure. The track housing 310 is connected to a support frame via multiple spaced-apart suspension mechanisms 200. The tilt position of the track assembly is controlled by extending and retracting the movable pull rods 220 of the suspension mechanisms at different positions. The two inflection points on the short side of the loop-shaped structure are arranged with one side higher than the other, forming a cross-shaped loop structure with twisting inflection points, as shown in the figure. This structure allows for better utilization of gravity during transport, improving transport efficiency and saving drive energy.

[0037] In this invention, such as Figure 1 As shown, the blocking mechanism 400 is located at both ends of the track housing 310, that is, a blocking mechanism 400 is provided at both ends of the loop-shaped track housing, and the blocking mechanism 400 is connected to the bottom of the hanging mechanism 200 located at both ends. Figure 5 As shown, the blocking mechanism 400 includes a lever 410 connected to the bottom of the hanging mechanism 200, a handle rod 420 connected to one end of the lever 410, a movable stop 430 connected to the other end of the lever 410, a return spring 440 connected between the lever 410 and the hanging mechanism 200, and a pressure switch 450 disposed at the bottom of the lever 410.

[0038] In this invention, the pressure switch 450 is connected to the electromagnetic coil 330. When the handle 420 is pulled down, the handle 420 drives the lever 410 to rotate around the hinge point between the lever 410 and the upper hanging mechanism 200, causing the movable stop 430 at the other end of the lever 410 to lift up, thus canceling the limit of the movable stop 430 on the track. At the same time, the pressure switch 450 on the lever 410 contacts the support of the lever 410 during the rotation, so that the pressure switch 450 is connected to the electromagnetic coil 330. While canceling the limit, the power is turned on and the conveying process begins. When the handle 420 is released, the handle 420 is reset by the return action of the return spring 440, and the movable stop 430 is engaged at the upper limit of the track assembly 300.

[0039] In this invention, such as Figure 6As shown, the hook assembly 500 is connected to the track housing 310. The hook assembly 500 includes a magnetic ring 510 that is sleeved on the outside of the track housing 310, a guide wheel 520 disposed on the upper end of the magnetic ring 510, and a hook 530 connected to the bottom of the magnetic ring 510. Anti-collision blocks 540 are provided on both sides of the hook 530 along the track conveying direction.

[0040] In this invention, the magnetic ring 510 is a U-shaped ring with an open top, which is snapped onto the track housing from bottom to top. Guide wheels 520 are provided at both ends of the U-shaped opening of the magnetic ring 510. The magnetic ring 510 is suspended outside the track housing 310 via the guide wheels 520. The guide wheels 520 are arranged with their axes inclined inwards, and their rolling surfaces are in close contact with both sides of the track housing 310. The axes of the guide wheels 520 are parallel to the direction of the inclined contact surfaces on both sides of the track housing 310, ensuring stable conveying. The top-opening magnetic ring 510 and guide wheels 520 are strategically positioned to securely engage with both sides of the track housing 310, avoiding the upper connection point of the track housing and ensuring a smooth conveying process.

[0041] When the electromagnetic coil 330 is energized, the magnetic ring 510 moves outside the track housing 310, with the guide wheel 520 as the moving support, realizing magnetic drive. Each hook 530 has anti-collision blocks 540 connected to both sides by connecting rods. The anti-collision blocks 540 are made of rubber material. The length of the connecting rod is determined according to the size of the conveying component. During the conveying process, the anti-collision blocks 540 separate adjacent hooks 530 to avoid contact and collision between adjacent workpieces, ensuring a smooth conveying process.

[0042] In this invention, when the handle 420 is pulled down, the pressure switch 450 contacts the support of the lever 410, connecting the circuit of the electromagnetic coil 330 to achieve magnetic drive. In the accumulation area, the magnetic drive is controlled by manually operating the handle 420 of the blocking mechanism 400, which drives the hook assembly 500 to move.

[0043] In this invention, such as Figure 1 , 2 As shown in Figure 3, the bottom of the hanging mechanism 200 is connected to a hook guide 600 via a connecting frame. The hook guide 600 includes two parallel and spaced guide rods arranged along the track direction. The hook 530 passes through the guide gap between the two guide rods. The hook guide 600 provides guidance for the moving hook 530, preventing the hook 530 from swinging back and forth and ensuring the stability of the transportation process.

[0044] In this invention, the track housing 310 is a hollow shell made of insulating material. The track housing 310 is rotatably connected at its inflection points, and the connection can be adjusted by rotating the connecting sleeve. This, combined with the telescopic movable pull rod 220, controls the tilting direction of the two tracks. The front and rear track housings 310 are arranged at an alternating tilt. The movable pull rod 220 is a telescopic connecting rod, either actuated or hydraulically telescopic, capable of moving and adjusting the track housing 310, and controlling the height of both sides of the track housing 310 to change the conveying direction.

[0045] In this invention, the anti-collision block 540 is supported and connected to both sides of the hook 530 by a connecting rod. It can be designed as a circular block. The track shell 310, the guide wheel 520 and the anti-collision block 540 are all made of insulating materials to avoid electrical conduction and leakage.

[0046] In this invention, two sets of symmetrically arranged conveyor structures are provided on both sides of the support frame 100. That is, the conveyor structures formed by the hanging mechanism 200, the track assembly 300, the blocking mechanism 400, and the hook assembly 500 are symmetrically arranged on both sides of the support frame 100, forming symmetrical production stations, which facilitates assembly line conveying and improves production efficiency.

[0047] In practical use, the workpiece is hung on the hook 530. When no power is applied, the hook assembly 500 slides down the slope of the track housing 310 under the action of gravity to move the workpiece for conveying. At the inflection point of the track, the movable stop 430 is raised by pulling down the handle 420. At this time, the hook assembly 500 can move on the track. At the same time, pulling down the handle 420 triggers the pressure switch 450, which energizes the electromagnetic coil 330 built into the track. The external magnetic ring 510 slides on the track under the action of magnetic force, driving the workpiece to move cyclically on the track.

[0048] In this invention, the movable pull rod 220 is a connecting rod with telescopic function, which can drive the track housing 310 to swing, change the height of both sides of the track housing 310, and change the conveying direction under the action of gravity.

[0049] A circulating suspended conveyor includes a support frame 100; a suspension mechanism 200 suspended on top of the support frame 100; a track assembly 300 connected to the bottom of the suspension mechanism 200, the track assembly 300 including a cross-shaped loop track housing with rotatable inflection points, a winding post 320 disposed within the track housing 310, and an electromagnetic coil 330 wound around the outside of the winding post; and a blocking mechanism 400 connected to the bottom of the suspension mechanism 200 and located at both ends of the track housing 310, the blocking mechanism 400 including a lever 410 connected to the bottom of the suspension mechanism 200 and a handle 42 connected to one end of the lever 410. 0. A movable stop 430 connected to the other end of the lever 410, a return spring 440 connected between the lever 410 and the hanging mechanism 200, and a pressure switch 450 disposed at the bottom of the lever 410; a hook assembly 500 movably connected to the track housing 310, the hook assembly 500 including a magnetic ring 510 sleeved on the outside of the track housing, a guide wheel 520 disposed at the upper end of the magnetic ring 510, a hook 530 connected to the bottom of the magnetic ring 510, and anti-collision blocks 540 disposed on both sides of the hook 530; when the handle lever 420 is pulled down, the pressure switch 450 contacts the support of the lever 410, connecting the circuit of the electromagnetic coil.

[0050] In this invention, the bottom of the hanging mechanism 200 is connected to a hook guide 600 via a connecting frame, which is used to guide the hook 530, prevent the hook 530 from swinging back and forth, and ensure a stable conveying process.

[0051] In this invention, the suspension mechanism 200 includes a suspension base 210, a movable pull rod 220, and a connecting block 230. The top of the movable pull rod 220 is hinged and fixed to the suspension base 210 on the support frame 100, and the bottom of the movable pull rod 220 is provided with a connecting block 230 that connects to the track housing 310. An adjusting screw for manually adjusting the height position is provided between the movable pull rod 220 and the connecting block 230. If the adjustment of the movable pull rod's extension and retraction control fails, the adjusting screw can be manually adjusted to control the height position, ensuring the normal operation of the conveying process.

[0052] In this invention, the track housing 310 is a hollow housing, with rotatable connections at the inflection points. The front and rear track housings 310 are arranged at an angle. The magnetic ring 510 is a U-shaped ring with an open top, suspended outside the track housing 310 by guide wheels 520. A loop-shaped track assembly 300 is used, with track rods on the front and rear sides arranged at an angle, allowing for height adjustments on both sides by rotating the inflection points. It can be conveyed by gravity sliding without power, saving drive energy. Blocking mechanisms 400 are provided at both ends of the track to control the conveying process. Pulling down the handle 420 raises the movable stop 430, allowing the hook assembly 500 to move on the track. Simultaneously, pulling down the handle triggers a pressure switch, energizing the electromagnetic coil inside the track. The external magnetic ring slides on the track under magnetic force, moving the hook and causing the workpiece on the hook to move cyclically on the track. This allows for loading on one side and unloading on the other, reducing manual labor intensity, shortening working hours, and improving work efficiency.

[0053] The purpose of this invention is to provide a circulating suspended conveying device, comprising: a support frame, a hanging mechanism, a track assembly, a blocking mechanism, and a hook assembly. The hanging mechanism is suspended on top of the support frame; the track assembly is connected to the bottom of the hanging mechanism, and the track assembly includes a cross-shaped loop track housing with rotatable inflection points, a winding post disposed within the track housing, and an electromagnetic coil wound around the outside of the winding post; the blocking mechanism is connected to the bottom of the hanging mechanism and located at both ends of the track housing. At the vehicle part placement position, the operator places the vehicle part onto the hanging mechanism and manually operates the blocking mechanism. The vehicle part follows the hanging mechanism and slides along the track, being conveyed by gravity. After the hanging mechanism B carries the workpiece to the accumulation position, the part stops. At the retrieval position, the operator manually retrieves the part and then manually operates the blocking mechanism. The hanging mechanism A can then slide on the track under magnetic force, moving the hook mechanism A to another track for hanging operations. The accumulation area's hanging mechanism B carries the parts to the retrieval position, where they can be retrieved. The hanging mechanism A is transported to the hanging end by gravity and then moved to the hanging position by magnetic force. This allows for manual placement of automotive parts on one side and manual retrieval of automotive parts on the other side. Furthermore, the blocking mechanism facilitates the accumulation of automotive parts, preventing the operation of the conveying mechanism from affecting the workshop's production rhythm, reducing manual labor intensity, shortening working hours, and improving work efficiency.

[0054] This invention relates to a circulating suspended conveyor device, which allows for manual placement of automotive parts on one side and manual removal of automotive parts on the other side, reducing labor intensity, shortening working hours, and saving energy. A blocking mechanism enables the accumulation of automotive parts, preventing the conveyor's operation from affecting the workshop's production rhythm. This circulating suspended conveyor device has a simple structure, low operating costs, and significantly saves manpower and resources, improving production efficiency. It has strong practicality and good application prospects.
