Description

Technical Field

[0001] This utility model relates to the field of conveying devices, and in particular to a gravity slide rail circulating conveying mechanism. Background Technology

[0002] Existing conveyor lines typically place workpiece pallets directly on the conveying medium, such as V-belts, synchronous belts, flat belts, round belts, and chains, moving synchronously with it. The conveying medium is responsible for both transporting the workpiece pallets and transmitting the system's power. This type of conveyor system, where the conveying medium is in direct contact with the workpiece pallets, is more prone to damage, has a shorter lifespan, and incurs higher maintenance costs. With the development of modern industrial technology, the requirements for production lines to be more flexible, automated, and cost-effective are increasing.

[0003] For example, utility model publication CN209758430U discloses a workpiece table transfer and conveying device. It includes a workpiece table, several conveyor belts, and a transfer mechanism. The workpiece table is mounted on the conveyor belts for transport. The transfer mechanism is used to transfer the workpiece table from the original conveyor belt to a target conveyor belt. The transfer mechanism operates at the intersection of two conveyor belts and includes a lifting platform and a conveyor. The conveyor is mounted on the lifting platform, and its transmission direction is towards the target conveyor belt. The lifting platform drives the conveyor to rise so that the conveyor contacts the workpiece table and transfers the workpiece table to the target conveyor belt, where it is then transported again.

[0004] However, the aforementioned existing technologies rely on conveyor belts or robotic arms to transfer workpieces, using drive motors to move the workpieces. This consumes significant energy during long-distance workpiece transport, resulting in high operating costs and rigid connections between structures. Therefore, there is a need for a workpiece conveying mechanism that offers low energy consumption and flexible transmission. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art, which has high energy consumption due to active transmission of the drive motor, resulting in high operating costs, and to provide a gravity slide rail circulating conveying mechanism.

[0006] The objective of this utility model can be achieved through the following technical solutions: A gravity slide rail circulating conveying mechanism includes a slide rail, a workpiece storage bracket, and a first adjustment component and a second adjustment component with the same structure. The first adjustment component and the second adjustment component are both support adjustment structures. The support adjustment structure includes a fixed frame, a sliding block, a cable, and a take-up and release unit. The sliding block is slidably mounted on the fixed frame in the vertical direction. The take-up and take-down unit is fixed on the fixed frame. One end of the cable is connected to the take-up and take-down unit and the other end is connected to the sliding block. The two ends of the slide rail are respectively fixed on the sliding blocks of the first adjustment component and the second adjustment component. The workpiece storage bracket is slidably fixed on the slide rail.

[0007] Preferably, the slide rail includes a transmission component and a first sub-slide rail and a second sub-slide rail that are parallel to each other and spaced apart, and the workpiece storage bracket includes a first storage sub-bracket and a second storage sub-bracket. The first storage sub-support is slidably mounted on the first sub-slide rail, and the second storage sub-support is slidably mounted on the second sub-slide rail. The two ends of the first and second sub-slide rails are respectively fixed on sliding blocks. The first and second storage sub-supports are diagonally distributed and connected by a transmission component.

[0008] Preferably, the transmission component includes a roller assembly and a transmission rope; The roller assembly is rotatably fixed on the first and second sub-slide rails. The roller assembly is arranged in a rectangular array on the side of the slide rails closest to the ground. The axis of rotation of the roller assembly is perpendicular to the plane of the slide rails. The transmission rope is installed around the circumference of the roller assembly. The first and second storage sub-supports are respectively fixed on the transmission rope.

[0009] Preferably, the roller assembly includes multiple rollers, and the outer ring of each roller is provided with an annular V-shaped groove that cooperates with the transmission rope.

[0010] Preferably, the workpiece storage bracket includes an H-shaped bracket, a carabiner, and a pulley assembly. The pulley assembly is slidably mounted on a slide rail. One end of the carabiner is fixed to the H-shaped bracket, and the other end is connected to the pulley assembly.

[0011] Preferably, the mechanism further includes a support frame, which is an L-shaped structure with one end fixed to the ground and the other end connected to a slide rail. The support frame is located between the first adjustment component and the second adjustment component.

[0012] Preferably, the take-up and take-down unit and the sliding block are located on both sides of the fixed frame, and the top of the fixed frame is provided with multiple guide pulleys, with the cable wound around the guide pulleys.

[0013] Preferably, the fixing frame is provided with an array of positioning holes along the sliding direction of the sliding block, and the sliding block is provided with positioning pins that cooperate with the positioning holes. The positioning pins are detachably installed in the positioning holes.

[0014] Preferably, the sliding block includes a fixed plate and a cam, the cam is rotatably mounted on the fixed plate, the slide rail is mounted on the fixed plate, one side of the fixed frame is provided with a guide groove that cooperates with the cam, and one end of the cable is connected to the fixed plate.

The fixed base is mounted on a fixed frame, the take-up reel is rotatably mounted on the fixed frame, the rotating handle drives and connects to the take-up reel, and one end of the cable is connected to the take-up reel.

[0016] Compared with the prior art, the present invention has the following advantages: (1) This solution uses adjustable slide rails at both ends, with an inclined slide rail and a workpiece storage bracket that can slide freely on the slide rail. This allows the workpiece mounted on the workpiece storage bracket to move towards the lower end of the slide rail based on its own weight, thus realizing the workpiece transfer. Compared with the existing method of using a drive motor to drive a transmission belt, this structure requires no additional drive, has low energy consumption, and reduces costs. Moreover, based on the cable-adjustable slide rail height, the entire transfer device is flexible, has strong impact resistance, and the transfer is more stable and reliable.

[0017] (2) This solution adopts a double-rail parallel structure, with two sliding workpiece storage sub-supports installed at opposite ends of the two sub-rails. The two sub-supports are connected by a transmission rope. The workpiece is placed on the higher sub-support and transferred to the lower end by gravity. At the same time, the lower sub-support is transferred to the higher end, which facilitates the next placement of the workpiece. This avoids the support reset operation, simplifies the conveying process, and improves the workpiece transmission efficiency. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model 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 limitations on this utility model.

[0023] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0024] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0025] Example 1 like Figure 1-3As shown, this embodiment provides a gravity slide rail circulating conveying mechanism, including a slide rail 1, a workpiece storage bracket 2, and a first adjustment component 3 and a second adjustment component 4 with the same structure. The first adjustment component 3 and the second adjustment component 4 are both support adjustment structures. The support adjustment structure includes a fixed frame 5, a sliding block 6, a cable 7, and a take-up and release unit 8. The sliding block 6 is slidably mounted on the fixed frame 5 in the vertical direction. The take-up and take-down unit 8 is fixed on the fixed frame 5. One end of the cable 7 is connected to the take-up and take-down unit 8, and the other end is connected to the sliding block 6. The two ends of the slide rail 1 are respectively fixed on the sliding blocks of the first adjustment component 3 and the second adjustment component 4. The workpiece storage bracket 2 is slidably fixed on the slide rail 1.

[0026] The first adjustment component 3 and the second adjustment component 4 are respectively installed at the beginning and end of the workpiece conveyor. The cable 7 is tightened by the take-up / release unit 8 at the beginning, causing the sliding block on that side to be pulled upwards. Simultaneously, the cable is released by the time unit at the end, causing the corresponding sliding block to move downwards. This results in the starting end of the slide rail being higher than the ending end, and the slide rail being tilted. The workpiece to be conveyed is placed on the workpiece storage bracket 2. Under the action of the workpiece's gravity, the workpiece storage bracket 2 moves along the slide rail towards the end, thus realizing the conveying of the workpiece.

[0027] The workpiece is conveyed by a workpiece storage bracket 2 that slides freely along the adjustable-height slide rails at both ends, allowing the workpiece mounted on the bracket to move towards the lower end of the slide rails under its own weight. Compared to existing conveyors that use a drive motor to power a transmission belt, this structure requires no additional drive, resulting in lower energy consumption and reduced costs. Furthermore, the cable-adjustable slide rail height makes the entire conveying device more flexible, impact-resistant, and provides more stable and reliable transmission.

[0028] Preferred implementation methods, such as Figure 2 As shown, the slide rail 1 includes a transmission component and a first sub-slide rail 101 and a second sub-slide rail 102 that are parallel to each other and spaced apart. The workpiece storage bracket 2 includes a first storage sub-bracket 201 and a second storage sub-bracket 202. The first storage sub-support 201 is slidably mounted on the first sub-slide rail 101, and the second storage sub-support 202 is slidably mounted on the second sub-slide rail 102. The two ends of the first sub-slide rail 101 and the second sub-slide rail 102 are respectively fixed on the sliding block. The first storage sub-support 201 and the second storage sub-support 202 are diagonally distributed and connected by a transmission component.

[0029] In this embodiment, as Figure 5 As shown, the transmission components include a roller assembly 103 and a transmission rope 104; The roller assembly 103 is rotatably fixed on the first sub-slide rail 101 and the second sub-slide rail 102. The roller assembly is distributed in a rectangular array on the side of the slide rail closest to the ground. The axis of rotation of the roller assembly is perpendicular to the plane of the slide rail. The transmission rope 104 is installed around the pulley assembly. The first storage sub-support 201 and the second storage sub-support 202 are respectively fixed on the transmission rope 104.

[0030] By adopting a dual-rail parallel structure, two slidable workpiece storage sub-supports are installed at opposite ends of the two sub-rails. The two sub-supports are connected by a transmission rope. Workpieces are placed on the higher sub-support and transferred to the lower end by gravity. At the same time, the lower sub-support is transferred to the higher end, which facilitates the next placement of workpieces. This avoids the need for support reset operations, simplifies the conveying process, and improves workpiece transfer efficiency.

[0031] In this embodiment, the roller assembly 103 includes multiple rollers, and the outer ring of each roller has an annular V-shaped groove that mates with the transmission rope 104. Four rollers can be used, installed at both ends of each sub-rail. The transmission rope is installed through the rollers, serving as a means of mutual transmission between the two workpiece sub-supports. Compared to rack and pinion drives, this structure is simpler and has a certain degree of cushioning effect.

[0032] In this embodiment, as Figure 4 As shown, the workpiece storage bracket 2 includes an H-shaped bracket 203, a carabiner 204, and a pulley system. The pulley system is slidably mounted on the slide rail 1. One end of the carabiner 204 is fixed to the H-shaped bracket 203, and the other end is connected to the pulley system. The height of the vertical bars on both sides of the H-shaped bracket 203 can be adjusted by the corresponding carabiner to keep the horizontal bar between the two vertical bars horizontal, thereby facilitating the loading and unloading of workpieces and improving the stability of workpiece transmission.

[0033] In this embodiment, the mechanism further includes a support frame 9, which is L-shaped with one end fixed to the ground and the other end connected to the slide rail 1. The support frame 9 is located between the first adjustment component 3 and the second adjustment component 4. By setting the support frame 9 at the middle position of the slide rail, the middle position of the slide rail is supported and fixed. The support frame is installed on the upper surface of the slide rail, avoiding any impact on the movement of the workpiece storage bracket 2 and improving the stability of the slide rail transmission. Moreover, the support frame 9 and the slide rail adopt a rotatable hinge structure, avoiding any impact on the height adjustment of both ends of the slide rail.

[0034] In this embodiment, the take-up and release unit 8 and the sliding block 6 are located on both sides of the fixed frame 5. The top of the fixed frame 5 is provided with multiple guide pulleys, and the cable 7 is wound around the guide pulleys.

[0035] Furthermore, the fixing frame 5 is provided with an array of positioning holes along the sliding direction of the sliding block 6, and the sliding block 6 is provided with positioning pins that cooperate with the positioning holes. The positioning pins can be detachably installed in the positioning holes.

[0036] In this embodiment, the sliding block 6 includes a fixed plate and a cam. The cam is rotatably mounted on the fixed plate, the slide rail 1 is mounted on the fixed plate, and a guide groove that cooperates with the cam is provided on one side of the fixed frame 5. One end of the cable 7 is connected to the fixed plate.

[0037] In this embodiment, the take-up and take-down unit 8 includes a fixed base, a take-up reel, and a rotating handle. The fixed base is mounted on a fixed frame, the take-up reel is rotatably mounted on the fixed frame, the rotating handle drives the take-up reel, and one end of the cable 7 is connected to the take-up reel.

[0038] Cable 7 is wound around the take-up reel, and the movable end can be secured with a clip. A guide pulley is used at the end of the fixed frame for steering, connecting it to a sliding block on the other side of the fixed frame. Turning the handle drives the take-up reel to release or retract the cable, which in turn moves the sliding block, allowing for quick and easy adjustment of the height at both ends of the slide rail. The sliding block is then secured by inserting locating pins into the locating holes, ensuring greater stability of the slide rail during workpiece transport.

[0039] This device is based on gravity conveying of workpieces. The specific working process is as follows: the fixed frame and support frame are installed on the floor. When it is necessary to transport the workpiece: ① By adjusting the length of the nylon rope, the left side of the gravity slide rail mechanism is lowered, and the right side of the slide rail is adjusted in the same way to raise its height, thus achieving a state where the left side is lower and the right side is higher.

[0040] ②Use carabiners to install two workpiece storage brackets diagonally to both ends of the slide rail, one on the left end and the other on the right end, with the two workpiece storage brackets installed on both sides of the slide rail respectively, and connect the two workpiece storage brackets with nylon rope.

[0041] ③ Place the workpiece on the workpiece storage bracket on the right end. At this time, due to gravity, the workpiece will slide from right to left along the slide rail to the predetermined position on the left, while the unloaded workpiece storage bracket on the left end will slide from left to right to the predetermined position on the right by the nylon rope.

[0042] ④ After removing the workpiece from the workpiece storage rack at the predetermined position on the left, place the unprocessed workpiece onto the workpiece storage rack at the predetermined position on the right. Similarly, the workpiece storage rack on the right descends, and the workpiece storage rack on the left rises, thus allowing the slide rail to reciprocate.

[0043] When transporting workpieces, depending on the processing requirements, the workpieces need to be moved from the left to the right. At this time, we only need to adjust the nylon ropes at both ends of the slide rail to make the left slide rail bracket rise and the right slide rail bracket fall. The rest of the operation steps do not need to be changed.

[0044] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
