[0075] One embodiment of the present invention provides a tray arrangement device, please refer to Figures 1 to 21 The pallet sorting device includes: a conveying platform 100, the conveying platform 100 includes a first load-bearing line 10 and a conveying line 50, the first load-bearing line 10 is located below the conveying line 50, the first load-bearing line 10 is used to carry an empty pallet 1, and the conveying line 50 is used to transport the empty pallet 1 loaded with luggage; a sorting platform 200, the conveying platform 100 is arranged adjacent to the sorting platform 200, the sorting platform 200 includes a second load-bearing line 20 and a luggage platform 60, the second load-bearing line 20 is located below the luggage platform 60, the second load-bearing line 20 is used to carry an empty pallet 1, and the luggage platform 60 is used to place the empty pallet 1 to be loaded with luggage; wherein, a first tray-taking port 110 is provided on the conveying platform 100, so as to obtain the empty pallet 1 on the first load-bearing line 10 through the first tray-taking port 110, and a second tray-taking port 210 is provided on the sorting platform 200, so as to obtain the empty pallet 1 on the second load-bearing line 20 through the second tray-taking port 210.

[0076] The pallet sorting device of one embodiment of the present invention is provided with a first pallet taking port 110 and a second pallet taking port 210 on the conveying platform 100 and the sorting platform 200, respectively, so that empty pallets 1 can be obtained from the first carrying line 10 and the second carrying line 20, respectively. That is, it can be used for passengers and security inspectors to obtain empty pallets 1 from different positions, avoiding the problem of disorder on site.

[0077] In one embodiment, the conveying platform 100 is mainly used for conveying, and the sorting platform 200 is mainly used for sorting passengers' luggage, that is, the empty pallet 1 is obtained from the second carrying line 20 and then placed on the luggage platform 60. After the luggage is placed in the empty pallet 1, it is transported through the conveyor line 50.

[0078] In one embodiment, the conveying platform 100 and the sorting platform 200 can be spliced ​​together. Of course, the two can also be an integral whole, which is not limited here.

[0079] In one embodiment, the first tray access opening 110 is arranged on the side of the conveying platform 100 away from the sorting platform 200, and the second tray access opening 210 is arranged on the side of the sorting platform 200 away from the conveying platform 100; wherein the first tray access opening 110 and the second tray access opening 210 are arranged opposite to each other. The first tray access opening 110 and the second tray access opening 210 are respectively located on both sides of the tray sorting device, that is, they correspond to the standing position requirements of the security inspector and the passenger respectively. Of course, in the case of a large passenger flow, it is not ruled out that the passenger stands at the first tray access opening 110.

[0080] In one embodiment, there are multiple first tray access openings 110 , which are spaced apart along the length direction of the first carrying line 10 , and / or there is only one second tray access opening 210 .

[0081] In one embodiment, there are multiple first tray-taking openings 110, each of which can take out an empty tray 1 at the same time, and there is one second tray-taking opening 210, which can take out multiple empty trays 1 at the same time; wherein, the number of empty trays 1 that can be taken out simultaneously by the second tray-taking opening 210 is equal to the number of the first tray-taking openings 110. The first tray-taking openings 110 are generally for security inspectors, so the number of empty trays 1 required is relatively small, and considering that the first carrying line 10 has a conveying function, the first tray-taking openings 110 are designed to be small, and their length can be used to take out one empty tray 1. The second tray-taking openings 210 are for passengers, so the number of empty trays 1 required is relatively large, so they are set to be large openings, and different passengers can take trays from a large opening.

[0082] like Figure 7 and Figure 8As shown, the tray sorting device also includes: a tray discharging mechanism 30, which includes a driving unit 31 and a flip assembly 32. The driving unit 31 is connected to the flip assembly 32 to drive the flip assembly 32 to rotate relative to the first load line 10, and to make the empty tray 1 on the first load line 10 detach from the first load line 10 and move along the flip assembly 32 to the second load line 20. The empty tray 1 is transmitted to the first load line 10, so it needs to be transferred to the second load line 20 by the tray discharging mechanism 30 for passengers to pick up the tray. This design method can not only form the recycling of the empty tray 1, but also there will be no problem of empty trays 1 piling up at the tray picking location, and the entire security inspection location is relatively simple.

[0083] 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.

[0084] 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 .

[0085] 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.

[0086] 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.

[0087] 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.

[0088] In one embodiment, an avoidance gap 11 is provided on the first carrying line 10; the first carrying line 10 is arranged adjacent to the second carrying line 20; the driving unit 31 is arranged below the first carrying line 10, and at least a portion of the flipping assembly 32 is arranged opposite to the avoidance gap 11; wherein the driving unit 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.

[0089] 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.

[0090] like Fig.12 As 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.

[0091] In one embodiment, the rolling portion 322 may be a rotatable component such as a roller or a ball, which is not limited here.

[0092] 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.

[0093] 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.

[0094] In one embodiment, the rotating frame 321 is a U-shaped frame, and the two rolling parts 322 are respectively disposed at two ends of the U-shaped frame.

[0095] In one embodiment, Figures 19 to 21 As shown, the first carrying line 10 is a roller conveyor line, which includes a plurality of first rollers 12, and an avoidance gap 11 is formed between two adjacent first rollers 12; wherein, the driving unit 31 is arranged below the first carrying line 10, and at least a portion of the flipping assembly 32 is arranged opposite to the avoidance gap 11 and is movable within the avoidance gap 11.

[0096] In one embodiment, both ends of the first roller 12 are respectively mounted on the frame 40 via a first support member 15 and a second support member 16, and one end of the first roller 12 is a driving end, that is, the power source drives one end of the first roller 12 to ensure that the first roller 12 rotates relative to the frame 40, thereby enabling the first roller 12 to drive the empty pallet 1 to move.

[0097] In one embodiment, the first carrying line 10 has the function of conveying the empty pallet 1 , that is, after conveying the empty pallet 1 to a preset position, the empty pallet 1 is moved to the second carrying line 20 through the pallet ejecting mechanism 30 .

[0098] like Fig. 20 As shown, a plurality of avoidance gaps 11 are formed between the plurality of first rollers 12 , and the first carrying line 10 further includes: a first support plate 13 , and some of the plurality of avoidance gaps 11 may selectively correspond to the first support plate 13 or the turning assembly 32 .

[0099] In one embodiment, considering that there are multiple first rollers 12, that is, there are multiple avoidance gaps 11, but not every avoidance gap 11 corresponds to a flipping assembly 32, a first support plate 13 can be provided in the avoidance gap 11 that does not correspond to the flipping assembly 32 to shield the avoidance gap 11. This setting can prevent objects or human bodies from accidentally extending into the avoidance gap 11.

[0100] In one embodiment, the first support plate 13 is a detachable part, that is, it can be added according to needs, and of course it can also be removed when the flip component 32 needs to be added. The whole design can meet the needs of different customers and improve the versatility of the device.

[0101] In one embodiment, the first support plate 13 is detachably disposed in the avoidance gap 11; wherein the first support plate 13 comprises a receiving groove, the notch of the receiving groove faces the empty pallet 1, and the plane where the bottom of the receiving groove is located is higher than the bottom of the first roller 12. The first support plate 13 disposed in the middle of the avoidance gap 11 has higher visualization and more reliable safety assurance.

[0102] In one embodiment, the bearing device further includes: a frame 40, the first bearing line 10 and the second bearing line 20 are both arranged on the frame 40, the driving unit 31 is hinged on the frame 40, and the flip assembly 32 is hinged on the frame 40; wherein the driving unit 31 includes a push rod 311, and the flip assembly 32 is hinged on the push rod 311, so that when the push rod 311 is extended, the flip assembly 32 is driven to rotate relative to the frame 40. When the driving unit 31 drives the push rod 311 to extend, the flip assembly 32 rotates relative to the frame 40, thereby rotating upward, so that the empty pallet 1 is separated from the flip assembly 32.

[0103] In one embodiment, the flip assembly 32 is disposed on the frame 40 via a first hinge assembly 33 , the driving unit 31 is disposed on the frame 40 via a second hinge assembly 34 , and the flip assembly 32 is also disposed on the push rod 311 via a second hinge assembly 34 .

[0104] like Fig.12 and Fig.15 As shown, the first hinge assembly 33 includes a first base 331, a first rotating shaft 332, a first bearing 333 and a first retaining spring 334.
