Description

Technical Field

[0001] This utility model relates to the technical field of suspended conveying devices, and in particular to a suspended workpiece suspension device for a suspended production line. Background Technology

[0002] Suspended production lines are a type of high-efficiency aerial material handling system. Their core feature is that workpieces are suspended on overhead tracks by hooks and moved continuously or intermittently by a drive unit.

[0003] In the automotive water pump production workshop, in order to facilitate the transfer and processing of water pump components in various workstations and factory spaces, an existing suspended conveyor line is adopted. The core structure includes a circular conveyor line, and then the bottom of the conveyor line is connected to hooks that are spaced apart. The workpiece is hooked on the hooks for spatial transfer.

[0004] The existing hook structure has some problems in use: the hook generally adopts a J-shaped structure, and the workpiece is hooked onto the hook through the assembly hole, but some problems are encountered when removing the workpiece. (Refer to...) Figure 1 When picking up a workpiece vertically upwards, it always hits the hook and is difficult to remove directly. Generally, only one method is used... Figure 2 The workpiece is removed by rotating it around the hook at a certain angle until the extension line of the hook is basically parallel to the workpiece's mounting hole. The worker has to hold the workpiece and rotate it at a certain angle to remove it, which is a cumbersome and inefficient process. Utility Model Content

[0005] The purpose of this invention is to solve the shortcomings of existing technologies where workers have to rotate the workpiece at a certain angle before they can remove it, and the upward rotation process is cumbersome and inefficient. Therefore, this invention proposes a suspended workpiece suspension device for a suspended production line.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A workpiece suspension device for a suspended production line includes a first hanging rod assembled with a suspended conveyor line, a second hanging rod movably connected to the first hanging rod, and an upwardly inclined insert rod rotatably connected to the bottom end of the second hanging rod via a horizontally set pin. An angle limiting structure is provided between the insert rod and the second hanging rod. The upper half of the insert rod is a straight rod portion, which is located on the first side of the second hanging rod. When suspending a workpiece, the workpiece is hooked onto the straight rod portion.

[0008] An extension rod extends from the end of the insertion rod away from the straight rod. The extension rod is located on the second side of the second hanging rod, and the second side is arranged opposite to the first side. The tilting limit structure includes a limit block fixed to the second side of the second hanging rod. The limit block is located on the upper side of the extension rod. When the extension rod abuts against the limit block, the insertion rod is at its maximum angle.

[0009] The limiting block is a permanent magnet, and the extension rod is a ferromagnetic metal part. The limiting block and the extension rod are magnetically attracted to each other.

[0010] The first hanging rod is rotatably connected to the second hanging rod via a hinge, and the hinge's pivot is arranged parallel to the pin.

[0011] The first hanging rod has a connected movable hole and a vertical slide rail. The movable hole is located directly above the vertical slide rail. The second hanging rod includes two vertical rod sections and one horizontal rod section distributed in an inverted U-shape. The horizontal rod section has flat sections on both sides. The horizontal rod section can switch between the movable hole and the vertical slide rail. When the horizontal rod section is inside the vertical slide rail, the flat sections are tangent to the wall of the vertical slide rail. When the horizontal rod section is inside the movable hole, the horizontal rod section can rotate freely along the horizontal axis.

[0012] The first hanging rod has an inclined surface in the area of ​​the movable hole, and the inclined surface is located directly above the vertical slide rail.

[0013] This utility model proposes a suspended workpiece suspension device for a production line. The advantages are as follows: This device, through the rotatable connection between the second hanging rod and the insert rod, the upward tilting structure of the insert rod, and the movable connection between the first hanging rod and the second hanging rod, allows the workpiece to naturally slide off along the straight and inclined sections after being pushed upwards. Unlike prior art devices, this eliminates the need to rotate and adjust the angle of the workpiece to achieve detachment. This structure effectively avoids the problem of interference between the workpiece and the hook when it is removed upwards, simplifying the removal action, improving workpiece retrieval efficiency, reducing operational difficulty, and lowering the labor intensity of workers.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 2-10 A workpiece suspension device for a suspended production line includes a first hanging rod 1 assembled with a suspended conveyor line. A second hanging rod 2 is movably connected to the first hanging rod 1. The bottom end of the second hanging rod 2 is rotatably connected to an upwardly inclined insert rod 9 via a horizontally set pin 7. An angle limiting structure is provided between the insert rod 9 and the second hanging rod 2. The upper half of the insert rod 9 is a straight rod part 15, which is located on the first side of the second hanging rod 2. When suspending a workpiece 10, the workpiece 10 is hooked on the straight rod part 15.

[0027] refer to Figures 4-6 In use, the mounting hole at one end of the workpiece hooks onto the straight rod section of the upper half of the insertion rod. The second hook rod is rotatably set by driving the insertion rod through a pin. When the operator needs to remove the workpiece, they only need to push the workpiece upwards, causing it to move upwards along the inclined direction of the insertion rod. As the workpiece moves upwards, the second hook rod 2 rotates relative to the first hook rod 1, and at the same time, the contact point between the workpiece and the insertion rod gradually moves away from the pin. Guided by the inclined structure of the insertion rod, the workpiece can automatically detach from the straight rod section, achieving a quick and easy removal of the workpiece.

[0028] This device, through the rotatable connection between the second hanging rod and the insert rod, the upward tilting structure of the insert rod, and the movable connection between the first hanging rod 1 and the second hanging rod 2, allows the workpiece to naturally slide off along the straight and inclined sections after being pushed upwards. Unlike prior art devices, this eliminates the need to rotate the workpiece to adjust its angle for detachment. This structure avoids the interference problem between the workpiece and the hook when being removed upwards, simplifies the removal process, improves workpiece retrieval efficiency, reduces operational difficulty, and lowers the labor intensity for workers.

[0029] An extension rod 11 extends from the end of the insertion rod 9 away from the straight rod part 15. The extension rod 11 is located on the second side of the second hanging rod 2. The second side is arranged opposite to the first side. The tilt limit structure includes a limit block 8 fixed to the second side of the second hanging rod 2. The limit block 8 is located on the upper side of the extension rod 11. When the extension rod 11 abuts against the limit block 8, the insertion rod 9 is at its maximum angle.

[0030] In one implementation, the limiting block 8 is a permanent magnet block, and the extension rod 11 is a ferromagnetic metal part. The limiting block 8 and the extension rod 11 are magnetically attracted to each other. The magnetic attraction causes the insertion rod 9 to return to the maximum opening angle so as to facilitate the placement of subsequent workpieces.

[0031] Of course, when the weight of the straight rod 15 is greater than the weight of the extension rod 11, gravity can also cause the insertion rod 9 to return to the maximum opening angle.

[0032] In one embodiment where the first hanging rod 1 and the second hanging rod 2 are movably connected, the first hanging rod 1 is rotatably connected to the second hanging rod 2 via a hinge, with the hinge's pivot parallel to the pin 7. When the workpiece 10 is pushed upward, the insert rod 9 passively rotates around the pin 7. The rotation of the insert rod 9 causes the second hanging rod 2 to rotate relative to the first hanging rod 1 around the hinge, thereby releasing any interference force that may occur between the insert rod 9 and the workpiece 10. This structure provides a controllable degree of freedom of movement during the upward unhooking process of the workpiece, preventing the insert rod 9 from getting stuck when the workpiece is lifted vertically, thus improving the reliability and smoothness of the unhooking process.

[0033] As another embodiment of the movable connection between the first hanging rod 1 and the second hanging rod 2, refer to Figures 4-6 The first hanging rod 1 has a connected movable hole 6 and a vertical slide rail 5. The movable hole 6 is located directly above the vertical slide rail 5. The second hanging rod 2 includes two vertical rod parts 12 and a horizontal rod part 13 distributed in an inverted U-shape. The horizontal rod part 13 has flat parts 14 on both sides. The horizontal rod part 13 can switch between the movable hole 6 and the vertical slide rail 5. When the horizontal rod part 13 is inside the vertical slide rail 5, the flat parts 14 are tangent to the wall of the vertical slide rail 5. When the horizontal rod part 13 is inside the movable hole 6, the horizontal rod part 13 can rotate freely along the horizontal axis. For example, the inner diameter of the movable hole 6 is larger than the cross-sectional size of the horizontal rod part 13. The first hanging rod 1 has an inclined surface 4 in the area of ​​the movable hole 6. The inclined surface 4 is located directly above the vertical slide rail 5.

[0034] Under normal conditions, the horizontal bar 13 is located within the vertical slide rail 5, and the flat part 14 is tangent to the wall of the vertical slide rail 5. This restricts the second hanging rod 2 relative to the first hanging rod 1 in the horizontal direction, allowing it to move only in a straight line up and down, thus ensuring stability and anti-swaying capability during the conveying process. The first hanging rod 1 has an inclined surface 4 in the area of ​​the movable hole 6. The inclined surface 4 is located directly above the vertical slide rail 5 and serves as a guide structure.

[0035] refer to Figure 3 , Figure 4 The sequence of workpiece suspension and detachment is as follows: workpiece 10 is hooked onto the straight rod 15 of the insertion rod 9 and moves with the conveyor line; (Reference) Figure 4 , Figure 5 When the workpiece needs to be removed, push the workpiece 10 upwards. Under the inclined guidance of the insertion rod 9, the workpiece drives the insertion rod 9 and the second hanging rod 2 to move upwards as a whole. In the vertical slide section 5, since the flat part 14 is tangent to the slide wall, the second hanging rod 2 remains locked in this stage and moves upwards with the workpiece. When the horizontal bar part 13 reaches the position of the movable hole 6, the flat part 14 disengages from the vertical slide section 5, and the horizontal bar part 13 rotates relative to the first hanging rod 1 under the guidance of the inclined surface 4, so that the second hanging rod 2 enters a rotatable state from a constrained state. (Reference) Figure 6 As the workpiece 10 continues to be pushed upwards, the insert rod 9 passively rotates around the pin 7, while the second hanging rod 2 rotates relative to the horizontal bar 13 until the workpiece 10 slides off the insert rod 9. The combination of the vertical slide rail 5 and the movable hole 6 not only locks the second hanging rod 2 during transport to reduce swaying, but also allows for controlled unlocking via the movable hole 6 and the inclined surface 4 during part removal, ensuring the reliability and safety of the disengagement action.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
