3. The high-speed baggage transfer tray of this application can be transported at high speeds at turns and up / down slopes, and to avoid damage to the baggage, separation of the baggage from the high-speed baggage tray, or the separation of baggage from the standard airline baggage tray; In the case of a power failure of the high-speed luggage conveying and sorting system, the high-speed luggage conveying tray can be self-starting and obtain power-driven movement on the track / conveyor of the high-speed luggage conveying and sorting system without the assistance of personnel. . And the tray has side guide wheels, which can correct the deviation during the conveying process, and reduce the friction and impact noise between the tray and the side guard; the bottom is more wear-resistant and can adapt to long-term running at high speed; the tray will not be on the sorting equipment. There is a risk of overturning or even getting off track.

4. The strip-shaped protrusions of the present application can enhance the friction of the upper surface of the tray, and the plurality of reinforcing ribs provided in the upper tray and the lower tray can make the overall strength of the upper tray and the lower tray. The multiple curved surfaces form an inclination structure to prevent luggage from flying out of the tray. The inclination and chamfer are set around the pallet. This is because the tracks are connected in sections. There is a gap between the segments or the height difference between the segments. The inclination or chamfer can avoid the connected pallets. The mutual influence makes the conveying of the pallet more smooth. The side guide wheels ensure that there is no jamming during the operation, and the matching structure with the side cover of the track is increased, especially in the high-speed conveying section, so that the pallet cannot fly out of the conveying track even if the pallet is stuck in time.

Better stability during operation.

6. The second advantage of the quick disassembly and assembly of the supporting roller device in this application is that the first and second stoppers are pulled inwardly by the spring, so that the two wheels at both ends of the expansion sleeve exert axial pressure inward. The oblique surface applies two forces to the wedge surface of the expansion sleeve, one is the horizontal pressure of the expansion sleeve inward, and the other is the pressure of the expansion sleeve vertically outward. The inclined surface of the wheel shaft will be tightened and open the expansion sleeve. The axial direction of the wheel clamps the expansion sleeve horizontally inward, and on the other hand, tightens the expansion sleeve vertically outwards, so as to fix the expansion sleeve and the axle, which plays a role of fastening, ensuring that the supporting wheel can be firmly maintained in the design position, and runs quietly and smoothly. When released, the second stopper is released from the spring, and the inward pressure disappears, causing the axle and the expansion sleeve to slacken.

In the picture

Indicates the pallet, and the state of the tipping unit is illustrated in the figure. The horizontal axis is 1 to 10, a total of 10 tilting mechanism units, and the conveying direction is from 1 to 10. The vertical axis is the sequence of the action process. Each increase of 1 in the serial number indicates that the tray has moved forward a distance of the width of the tilting unit. The 10 units of the system have the same width, L1, and the gap between the units is small and can be ignored. The distance between the sensor installation position and the end of the unit is L4. The conveying module's conveying speed is stable at V1, the length of the luggage carrying container is L2, and the distance between the containers is L3. The dumping action time of the unloading mechanism is T1 and the return time is T2. The efficiency is P. Then there is the following relationship: (2 × L1) / V1>T1; L3 / V1> ((2 × L1) / V1 + T2); P = 3600 × V1 / (L2 + L3) where L1 and L2 are in mechanical design Already fixed. L4 = 3 × L1-L2.

The high-speed luggage transfer tray 1 can be transported at high speeds at turns and up / down slopes, and avoids damage to luggage, separation of luggage from the high-speed luggage transfer tray 1, or the separation of luggage from standard airline luggage trays. In the event of a power failure in the conveying and sorting system, the high-speed baggage conveying tray 1 can be self-started and obtain power-driven movement on the rails / conveyors of the high-speed baggage conveying and sorting system without the assistance of personnel. And the tray has side guide wheels, which can correct the deviation during the conveying process, and reduce the friction and impact noise between the tray and the side guard; the bottom is more wear-resistant and can adapt to long-term running at high speed; on the sorting equipment, the tray 201 is not There is a risk of overturning or even getting off track.

The strip-shaped protrusion 210 of the present application can enhance the frictional force on the upper surface of the tray, and the plurality of reinforcing ribs provided in the upper tray 201 and the lower tray 202 can make the overall strength of the upper tray 201 and the lower tray 202. The multiple curved surfaces form an inclination 207 structure, which can prevent luggage from flying out of the tray. At the same time, it can make the luggage sorting process smoother and reduce the impact of the luggage during the sorting process. The inclination 207 and chamfer are set around the pallet. This is because the tracks are connected in sections. There is a gap between the sections or the height difference between the sections. The setting of the inclination 207 or the chamfer can avoid connection. The pallets affect each other, which makes the conveying of the pallets more smooth. The side guide wheels ensure that there is no jamming during the operation, and the matching structure with the side cover of the track is increased, especially in the high-speed conveying section, so that the pallet cannot fly out of the conveying track even if the pallet is stuck in time.

The stacking slot 206 and the stacking protrusion 209 facilitate the taking and placing of the tray during stacking. It can also ensure that pallets stacked together are stacked more firmly during transportation. The upper surface of the pallet can provide reasonable friction. The friction coefficient between the surface of the luggage and the upper surface of the pallet (accommodating surface) is 0.25 to 0.83, which can prevent luggage from contacting the upper surface of the pallet during turning, high-speed transportation, up / downhill, etc. ( (Acceptance surface) has a clear relative movement trend or even slips. In severe cases, luggage flies out of the tray; 0.5 to 0.8 of the lower surface of the tray and the upper surface of the conveyor belt can prevent the tray from turning, high-speed transportation, up / downhill, etc. During the process, there is a clear relative movement trend or even sliding on the upper surface of the conveyor belt; the upper surface (accommodating surface) of the tray has a strong anti-wear ability, which avoids the luggage in the process of turning, high-speed transportation, up / downhill, etc. The upper surface (accommodating surface) of the tray has obvious relative movement tendency and even slips. Each baggage high-speed transfer tray 1 has a unique identification code, which is stored on the permanent RFID tag in a machine-readable format in the baggage high-speed transfer tray 1. The RFID tag can be replaced without damaging the tray; there is a drainage opening at the bottom of the tray for the high-speed luggage delivery tray 1 to prevent water accumulation in the tray.

The upper tray 201 is designed as a thin-walled hollow structure with an average thickness of about 3 to 5 mm. In order to prevent stress deformation and increase the overall strength, appropriate reinforcing ribs are set in the middle. At the same time, there is a clip structure connected to the lower tray 202.

The pallet is subjected to centrifugal force during the turn, and friction and inclination 207 are required to provide centripetal force to prevent luggage from flying out of the pallet.

During the field test, it was found that during the operation of the up and down track, the luggage is easy to slide in the tray in the running direction. In order to solve this problem, in addition to increasing the surface friction coefficient, it is proposed to use a raised structure, which will help improve the overall tray. Strength to prevent the tray from deforming under heavy load.

Because the tracks are connected in sections, there are gaps or step height differences between the sections, so the pallet needs to be set with a chamfer and inclination 207.

Add a matching structure with the track side cover, especially the high-speed conveying section, so that the pallet cannot fly out of the conveying track even if the pallet jams in time.

Two forces, one is the horizontal pressure inward of the expansion sleeve 404, and the other is the vertical pressure of the expansion sleeve 404. The inclined surface 410 of the axle 405 will press tightly and open the expansion sleeve 404. The expansion sleeve 404 is clamped horizontally inside, and the expansion sleeve 404 is tightly tightened vertically outwards, so that the expansion sleeve 404 and the axle 405 are fixed, which plays a fastening role, ensuring that the supporting wheel 402 can be firmly maintained in the design position, quiet and stable. When it is released, the second stop claw 412 disengages from the spring 406, the inward pressure disappears, and the axle 405 and the expansion sleeve 404 are loosened. The axle 405 is quickly removed to ensure convenient assembly and disassembly and replacement of parts. When parts are damaged, they can be replaced quickly, which is convenient for maintenance and shortens the repair time.
