Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of the present disclosure.

[0059] An embodiment of the present invention provides a bearing device, please refer to Figures 1 to 21 The carrying device is used to carry the empty pallet 1, and the carrying device includes: a first carrying line 10, on which an avoidance gap 11 is arranged; a second carrying line 20, the first carrying line 10 and the second carrying line 20 are arranged adjacent to each other; a tray-spitting mechanism 30, which includes a driving part 31 and a flipping assembly 32, the driving part 31 is arranged below the first carrying line 10, and at least a part of the flipping assembly 32 is arranged opposite to the avoidance gap 11; wherein the driving part 31 is drivingly connected to the flipping assembly 32 to drive the flipping assembly 32 to rotate relative to the first carrying line 10, and to make the empty pallet 1 located on the first carrying line 10 detach from the first carrying line 10 and move along the flipping assembly 32 to the second carrying line 20.

[0060] The load-bearing device of one embodiment of the present invention comprises a first load-bearing line 10, a second load-bearing line 20 and a tray-discharging mechanism 30, and the tray-discharging mechanism 30 can transfer the empty pallet on the first load-bearing line 10 to the second load-bearing line 20. That is, when conveying an empty pallet 1, the empty pallet 1 can be conveyed only to the first load-bearing line 10, and then transferred by the tray-discharging mechanism 30. Compared with the prior art in which one conveying line can only meet the needs of one platform receiving an empty pallet, the load-bearing device can transfer the empty pallet 1 from the first load-bearing line 10 to the second load-bearing line 20, thereby meeting the tray-taking requirements at different positions.

[0061] In one embodiment, when the driving unit 31 drives the flip assembly 32 to rotate upward, the flip assembly 32 contacts the empty pallet 1 located on the first carrying line 10, and since one end of the flip assembly 32 is raised, the empty pallet 1 will move along the flip assembly 32 and thus be transferred to the second carrying line 20.

[0062] like Fig.12As shown, the flip assembly 32 includes: a rotating frame 321, the driving unit 31 is drivingly connected to the rotating frame 321 to drive the rotating frame 321 to rotate relative to the first carrying line 10; and a rolling portion 322, the rolling portion 322 is arranged on the rotating frame 321, and at least a part of the rolling portion 322 is rotatably arranged relative to the rotating frame 321, so that when the rolling portion 322 passes through the avoidance gap 11 and contacts the empty pallet 1, the empty pallet 1 is movably arranged along the rolling portion 322. The driving unit 31 drives the rotating frame 321 to rotate, and the rotating frame 321 drives the rolling portion 322 to rotate upward, at which time the empty pallet 1 will move along the rolling portion 322, and because the rolling portion 322 is a rotating member, the friction between the empty pallet 1 and the rolling portion 322 is reduced, and the empty pallet 1 is more likely to be separated from the rolling portion 322.

[0063] In one embodiment, the rolling portion 322 may be a rotatable component such as a roller or a ball, which is not limited here.

[0064] In one embodiment, the rolling portion 322 is a smooth bar, which is arranged opposite to the avoidance gap 11 and is movably arranged in the avoidance gap 11. In the original state, the smooth bar can be stored in the avoidance gap 11 or located below the avoidance gap 11, and preferably does not contact the empty pallet 1. When the empty pallet 1 is transferred, the rolling portion 322 will be rotated out of the avoidance gap 11, thereby driving the empty pallet 1.

[0065] In one embodiment, the tray discharging mechanism 30 is used to be arranged in one-to-one correspondence with the empty trays 1, so that the flip assembly 32 moves the empty tray 1 located on the first load line 10 and corresponding to the first tray taking opening 110 to the second load line 20, and makes the empty tray 1 correspond to the second tray taking opening 210. When the empty tray 1 is located at the position of the flip assembly 32, the empty tray 1 corresponds to the first tray taking opening 110, that is, the empty tray 1 can be directly taken out from the first tray taking opening 110 without position adjustment, and after the empty tray 1 is transferred to the second load line 20 by the flip assembly 32, the empty tray 1 corresponds to the second tray taking opening 210, and the passenger can directly take the empty tray 1 without position adjustment.

[0066] In one embodiment, there are multiple tray ejecting mechanisms 30 , and the multiple tray ejecting mechanisms 30 are independently arranged to drive multiple empty trays 1 to be transferred to the second carrying line 20 .

[0067] In one embodiment, the driving part 31 of the plate spitting mechanism 30 adopts an electric push rod, a crank 4-bar mechanism, a cylinder, a small power cylinder, etc., and the plate spitting angle β of the flipping component 32 is 0-30°. Among them, the driving part 31 can adopt an electric push rod and a stepper motor combination, an electric push rod and a servo motor combination, a cylinder as an actuator, compressed air pushes the cylinder to complete, or an oil cylinder as an actuator, a hydraulic pump, and hydraulic oil push the cylinder to complete. The flipping angle can be set according to the needs. The larger the angle, the faster the plate is spitted, and the smaller the angle, the slower the plate is spitted.

[0068] In one embodiment, the driving part 31 has a fixed end, and the fixed end is connected and hinged on the frame 40 by using a sheet metal structure, a carbon steel plate, an alloy steel, or a profile. A rolling bearing, an oil-free bushing, a fisheye bearing, and an oil-containing sealed bearing are arranged between the first rotating shaft 332 of the first hinge assembly 33 and the first base 331 to reduce friction. The first rotating shaft 332 is fixed on both sides by a shaft retaining spring, fixed by a single-side shaft shoulder, and fixed by a movable end on the other side. The movable end can be fixed by a retaining spring, a cotter pin, a thread, or the like.

[0069] In one embodiment, the rotating frame 321 is formed by welding a whole sheet metal, welding and splicing a sheet metal segment, splicing after cutting a profile, or bending a plate. The rolling part 322 can directly use a smooth bar, or the flip assembly 32 uses a structural support (rotating frame 321) + rolling bearing (rolling part 322), a structural support (rotating frame 321) + a rotating body (rolling part 322), etc.

[0070] In one embodiment, there are multiple avoidance gaps 11, which are arranged at intervals along the length direction of the first carrying line 10, and there are multiple rolling parts 322, which are arranged one by one corresponding to the multiple avoidance gaps 11, so as to drive the empty pallet 1 to leave the first carrying line 10 through the multiple rolling parts 322. A tray ejection mechanism 30 includes a driving part 31 and a flip assembly 32, and the flip assembly 32 can ensure a rotating frame 321 and multiple rolling parts 322 arranged on the rotating frame 321, so as to stably lift the empty pallet 1.
