Description

Technical Field

[0001] The present invention relates to the technical field of painting transportation, and particularly to a swinging track. Background Art

[0002] Currently, the most advanced pre-treatment electrophoresis transportation method is a tipping conveyor. The tipping conveyor uses a heavy-duty track and a light-duty track in combination. The tipping conveyor can travel straight and tip on the track.

[0003] Chinese Patent CN208585707U discloses a vehicle body transportation system and a vehicle body pre-treatment and electrophoresis system. The tipping machine can only run straight along the track, and the switching between rotation lines needs to be realized by adding a turntable.

[0004] Currently, there is a self-rotating tipping conveyor that cancels the turntable. The tipping machine conveyor can run along a straight track and an arc track. When the tipping machine travels completely straight or completely in an arc, the walking wheels on the light-load side of the tipping machine do not wear severely. When the tipping machine just finishes straight walking and before it just starts to walk completely in an arc, or when the tipping machine just finishes walking completely in an arc and before it just starts straight walking, during this process, the walking wheels on the light-load side of the tipping machine will walk irregularly, resulting in rapid wear of the walking wheels on the light-load side. Summary of the Invention

[0005] To solve the above problems, the present invention provides a swinging track to solve this problem.

[0006] To achieve the above object, the present application provides the following technical solutions:

[0007] The swinging track includes a transportation line, a swinging curved rail, a first leg and a second leg for support. One end of the swinging curved rail is rotatably connected to the first leg, and the other end can swing along the second leg. A return force providing member is provided between the first leg and the swinging curved rail for the swinging curved rail to return to its original position after swinging.

[0008] Further, a rotating shaft assembly is provided on the first leg. One end of the swinging curved rail is connected to the rotating shaft assembly, and the swinging curved rail realizes a rotating motion along the first leg through the rotating shaft assembly.

[0009] Further, a first bracket is provided on the first leg. The rotating shaft assembly includes a bushing provided on the first bracket. A rotating shaft connected to the swinging curved rail is rotatably provided in the bushing, and a bearing for reducing friction is sleeved on the outer wall of the rotating shaft.

[0010] Further, a second bracket is provided on the second leg. An arc-shaped rail is provided on the upper surface of the second bracket, and a roller that can roll along the arc-shaped rail is rotatably provided at the bottom of the swinging curved rail.

[0011] Further set as: stoppers are respectively arranged on both sides of the top of the second bracket.

[0012] Further set as: polyurethane blocks are installed on the end faces of the two stoppers facing each other.

[0013] Further set as: an installation plate is arranged on one side of the second bracket close to the first bracket, one end of the return force providing member is connected to the installation plate, and the other end is connected to the swing curved rail.

[0014] Further set as: the return force providing member is one of a door closer, a spring or a gas spring.

[0015] Further set as: two return force providing members are provided, and the two return force providing members are respectively located on both sides of the swing track.

[0016] Further set as: a plurality of rollers are arranged on the swing curved rail.

[0017] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0018] Through the rotation action of the swing curved rail, the present invention effectively cancels the torsional force between the walking wheels on the light load side of the tilter and the track, avoids the rapid wear of the walking wheels on the light load side, extends the service life of the equipment, makes the tilter more stable and smooth when converting between the straight track and the arc track, reduces the operation failures caused by the track connection problems, and enhances the reliability and stability of the entire conveying system.

[0019] Compared with the self-rotating tilter conveyor system without a swing track, when the tilter just finishes straight walking and before it just completely starts walking on the arc, or when the tilter just completely finishes walking on the arc and before it just starts straight walking, when the tilter walks during this process, the swing track can rotate and swing to cancel the torsional force between the walking wheels on the light load side and the track, and avoid the occurrence of rapid wear and severe noise of the walking wheels on the light load side.

[0032] Embodiment 1

[0033] Refer to Figures 1 - 5 , which is the swing track disclosed in the present invention, including a transportation line 0, a swing curved rail 3, a first leg 1 and a second leg 2 for support. The swing curved rail 3 is arranged on the first leg 1 and the second leg 2, and the swing curved rail 3 can perform a swing action and is used to support the walking wheels on the light load side of the tilter.

[0034] In this embodiment, the shape of the swing curved rail 3 is a sector, and it can also be other shapes.

[0035] The first leg 1 is arranged at the junction of the straight track 001 and the arc track 002 of the transportation line 0. A first bracket 4 is arranged on the first leg 1, and a rotating shaft assembly 5 is arranged on the first bracket 4. One end of the swing curved rail 3 is connected to the rotating shaft assembly 5, and the swing curved rail 3 rotates along the first leg 1 through the rotating shaft assembly 5.

[0036] Among them, the rotating shaft assembly 5 includes a bushing 11 arranged on the first bracket 4. A rotating shaft 12 connected to the swing curved rail 3 is rotatably arranged in the bushing 11, and a bearing 13 for reducing friction is sleeved on the outer wall of the rotating shaft 12.

[0037] In this embodiment, the rotating shaft assembly 5 can cooperate with multiple bearings 13, and the rotation mode of the rotating shaft assembly 5 can be through the bearing 13 or other means.

[0038] A second bracket 6 is arranged on the second leg 2. The end of the swing curved rail 3 far from the rotating shaft assembly 5 can walk and swing on the second bracket 6. Specifically, an arc track 9 is arranged on the upper surface of the second bracket 6, and a roller 10 capable of rolling along the arc track 9 is rotatably arranged at the bottom of the swing curved rail 3.

[0039] In this embodiment, two stoppers 14 are respectively arranged on both sides of the top of the second bracket 6. Both stoppers 14 are arranged on the walking path of the swing curved rail 3 to prevent the swing curved rail 3 from swinging out of the track system, and a polyurethane block 15 is installed on the opposite end faces of the two stoppers 14.

[0040] On one side of the second support 6 close to the first support 4, there is a mounting plate 7. On the side of the mounting plate 7 facing away from the second support 6, a return force providing member 8 is installed. The other end of the return force providing member 8 is connected to the swing curved rail 3;

[0041] In this embodiment, the return force providing member 8 includes but is not limited to: a door closer, a spring, a gas spring, or other similar forms, or other structural forms.

[0042] When the tilter enters the swing curved rail 3 from the straight rail 001, the swing curved rail 3 starts to swing with the rotating shaft assembly 5 on the first leg 1 as the rotation center. This swinging action can effectively offset the torsional force between the walking wheels on the light load side of the tilter and the rail, thereby avoiding the rapid wear of the walking wheels on the light load side and extending the service life of the equipment. At the same time, one end of the swing curved rail 3 far from the rotating shaft assembly 5 travels along the arc rail 9 on the second support 6 of the second leg 2 through the roller 10, assisting the swing curved rail 3 to complete the swinging action, making the tilter more stable and smooth when switching between the straight rail 001 and the arc rail 9. When the tilter leaves the swing curved rail 3, the return force providing member 8 pulls the swing curved rail 3 back to its original position. This design ensures that the swing curved rail 3 can quickly return to its initial position to prepare for the passage of the next tilter;

[0043] The stoppers 14 on both sides of the top of the second support 6 limit the swinging range of the swing curved rail 3, preventing it from swinging out of the rail system, avoiding equipment failures and safety accidents, and improving the safety and reliability of equipment operation. The polyurethane blocks 15 installed on the opposite end faces of the stoppers 14 can effectively reduce the collision and friction between the swing curved rail 3 and the stoppers 14, further reducing noise.

[0044] Embodiment 2

[0045] Refer to Figures 6 - 7 , the difference from Embodiment 1 is that in this embodiment, the area of the swing rail is increased so that no matter whether the swing curved rail 3 rotates clockwise or counterclockwise, the walking wheels on the light load side of the tilter can fall on the swing curved rail 3; and a plurality of rollers 10 are provided on the swing curved rail 3 to enhance the supporting force for the swing curved rail 3; in this embodiment, two return force providing members 8 are provided, and the two return force providing members 8 are respectively located on both sides of the swing rail. With this setting, the swing curved rail 3 can meet the requirements of bidirectional swinging walking.

[0046] Specifically, different from the single positioning of the swing rail in Embodiment 1 after reset, the swing rail in this embodiment is in an equilibrium position when stationary. The two door closers are symmetrically stretched like springs, which can ensure that the swing curved rail 3 can accurately return to its original position after bidirectional swinging.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention.
