Abstract
Description
Technical Field
[0001] This invention relates to the field of airport transportation equipment technology, and more specifically to an airport roller conveyor. Background Technology
[0002] Currently, the airport cargo area is processing departing cargo in a direct-access mode, with manual baggage inspection. Security personnel and on-site operators control the roller line at the bottom of the security inspection machine and the roller line at the end of the line, respectively. There is no linkage between the two roller lines.
[0003] Due to potential delays in manual operation and a lack of coordination between production lines, goods may fall after being squeezed at the end of the roller conveyor. Furthermore, when there is an excessive volume of goods awaiting inspection or when goods are palletized, the roller conveyor must be stopped so that on-site security personnel can process the goods and arrange for forklifts to remove the palletized goods. Additionally, goods that have already been inspected on the roller conveyor need to be transported separately to prevent mixing of goods awaiting and completed inspection. Therefore, we propose a roller conveyor for airport use. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides an airport roller conveyor that overcomes these limitations. By installing a non-powered roller and partition baffles at the tail end of the second roller conveyor section, the forward rolling distance of goods is reduced, and goods are prevented from falling directly onto the conveyor line. When used in conjunction with folding roller conveyors, inspected goods can slide down the folding roller conveyor and be concentrated below the conveyor line without stopping the line. This avoids interfering with normal conveyor operation and allows workers to transport inspected goods in batches, reducing labor costs and improving efficiency. By incorporating limit guide rails and displacement components, the partition baffles are pushed open segment by segment as goods gradually accumulate at the tail end, controlling the distance the baffles advance each time. This ensures the partition baffles effectively block the goods while preventing excessive compression of the goods at the tail end.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] An airport roller conveyor is characterized in that it includes: a roller conveyor line, which is divided into a first roller conveyor section with a longer stroke and a second roller conveyor section with a longer stroke, wherein the rollers in the tail end range of the second roller conveyor section are designed as unpowered rollers, and a partition baffle is slidably installed at the tail end of the second roller conveyor section.
[0007] Preferably, slide rails are installed on the frame on both sides of the tail end of the second roller conveyor section, and correspondingly, guide grooves adapted to the slide rails are opened at the bottom of the partition baffle.
[0008] Preferably, the bottom of the partition baffle is hinged with a folding roller between the lower frame of the second roller conveying part, and the folding roller gradually unfolds as the partition baffle gradually moves away from the tail end of the second roller conveying part and forms a spacing.
[0009] Preferably, the folding roller comprises at least three pairs of hinged links, a plurality of rollers are installed between each pair of links, the first pair of links is hinged with the lower frame of the second roller conveying part, the second pair of links is hinged with the bottom of the partition baffle, and the remaining pairs of links are hinged with each other and integrated with the first and second pairs of links.
[0010] Preferably, the tail end frame of the second roller conveying part is further provided with a limiting guide rail on both sides, a guide groove is formed in the limiting guide rail, and a displacement member adapted to the limiting guide rail is installed on both ends of the partition baffle.
[0011] Preferably, the guide groove is divided into a positioning part and a homing part, the positioning part comprises a plurality of continuous recessed structures, the bottom of the recessed structure is semicircular, the recessed structure near the side wall of the first roller conveying part is vertical, and the other side wall is connected with the side wall of the adjacent recessed structure in a circular arc transition; the homing part is formed above the positioning part and is communicated with each other; the middle part of the homing part is a straight groove, and a buffer window is formed at one end near the first roller conveying part.
[0012] Preferably, the displacement member comprises a connecting plate fixedly installed on the partition baffle, one end of the connecting plate is hinged with a swing block, and the other end of the swing block moves along the guide groove.
[0013] Preferably, a space for forklifts to pick up the pallets is formed in the partition baffle, and a plurality of rubber bumpers are attached to the outer surface of the partition baffle for buffering.
[0014] The present application provides an airport roller conveyor. It has the following advantages:
[0015] 1. By installing a non-powered roller and a partition baffle at the tail end of the second roller conveying part, the travel distance of the goods rolling forward can be reduced, and the goods directly falling off the conveying line can be blocked.
[0016] 2. By using the partition baffle with the folding roller, the goods that have been inspected can be slid off the folding roller and concentrated under the conveying line without stopping the conveying line, which not only does not interfere with the normal operation of the conveying line, but also allows the workers to transport the goods that have been inspected in batches, reducing labor costs and improving efficiency.
[0017] 3. By setting the limiting guide rail strip and displacement piece, when the tail end goods are gradually accumulated, the force of the partition baffle is pushed away one by one, the distance of the forward movement of the partition baffle is controlled, the blocking effect of the partition baffle on the goods is ensured, and the mutual extrusion of the tail end goods is avoided.

[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0029] Referring to the drawings Figs. 1-3 A roller conveyor for airport, comprising a roller conveying line, the conveying line is divided into two sections, and the roller conveying line is erected on a rack, one section is a first roller conveying part 1, the other end is a second roller conveying part 2, the stroke of the first roller conveying part 1 is longer, mainly used for accumulating goods, providing sufficient time for personnel to judge the package;
[0030] The stroke of the second roller conveying part 2 is short, and the rollers in the tail end range of the second roller conveying part 2 are designed as unpowered rollers, that is, not connected to the power chain, and at least one diffuse reflection photoelectric sensor is installed between the unpowered roller and the nearest powered roller. When the goods of the second roller conveying part 2 reach the position of the photoelectric sensor and are identified by the photoelectric sensor, the roller conveying part automatically stops. It can be understood that the photoelectric sensor and the second roller conveying part 2 are electrically connected, and a conventional electrical control mode can be used.
[0031] In some embodiments, the length of the first roller conveying part 1 is designed to be 4600mm, and the length of the second roller conveying part 2 is designed to be 1600mm, and the widths of both are set to meet the single 1200*1000mm pallet specification.
[0032] The unpowered roller is mainly used to reduce the stroke amount of the forward rolling of the goods.
[0033] A separation baffle 3 is slidably installed at the tail end of the second roller conveying part 2. Specifically, slide rails are respectively installed on the racks on both sides of the tail end, and correspondingly, guide grooves are formed in the bottom of the separation baffle 3 to match the slide rails. Intervals are formed in the separation baffle 3 for the forklift to pick up the pallets, so as to facilitate the connection of the pallet goods by the forklift. In order to avoid damage to the separation baffle 3 caused by the impact of the forklift, a plurality of rubber bumpers are attached to the outer surface of the separation baffle 3 to provide cushioning and reduce the risk of damage to the separation baffle 3 caused by the misoperation of the forklift.
[0034] A folding roller 4 is hingedly connected between the bottom of the separation baffle 3 and the lower rack of the second roller conveying part 2. In the initial state, the separation baffle 3 is attached to the tail end of the second roller conveying part 2. As the goods on the tail end gradually accumulate, the goods will push the separation baffle 3 away from the tail end and expand the folding roller 4. When the folding roller 4 is fully expanded, there is a gap between the separation baffle 3 and the tail end of the second roller conveying part 2, and the size of the gap should be sufficient for the goods to fall from the gap to the roller below. When the tail end has too many goods, the worker can make the goods fall from the gap and slide down to the bottom of the expanded folding roller 4 after checking the goods. The bottom goods are transported at one time, and the conveying line workers can continue to check without being affected. It should be noted that the pallet goods cannot fall from the gap and need to be unloaded by a forklift.
[0035] The folding roller 4 includes at least three pairs of hingedly connected continuous links. Each pair of continuous links is provided with a plurality of rollers. It can be understood that the first pair of continuous links is hingedly connected to the lower rack of the second roller conveying part 2, the second pair of continuous links is hingedly connected to the bottom of the separation baffle 3, and the remaining pairs of continuous links are hingedly connected to each other and integrated with the first and second pairs of continuous links.
[0036] The tail end frame of the second roller conveying part 2 is also provided with a limiting guide rail strip 5 on each side, the limiting guide rail strip 5 is provided with a guide groove, the two ends of the partition baffle 3 are provided with displacement pieces 6 matched with the limiting guide rail strip 5, the displacement pieces 6 move along the guide groove, the guide groove is divided into a positioning part 51 and a homing part 52, the positioning part 51 comprises a plurality of continuous recess structures, the bottom of the recess structure is semicircular, the recess structure near the side wall of the first roller conveying part 1 is vertical, and the other side wall is connected with the side wall of the adjacent recess structure in a circular arc transition, the homing part 52 is arranged above the positioning part 51 and communicates with each other; the middle part of the homing part 52 is a straight groove, and a buffer window is formed at one end close to the first roller conveying part 1.
[0037] The displacement piece 6 comprises a connecting plate 61 fixedly installed on the partition baffle 3, one end of the connecting plate 61 is hinged with a swing block 62, the other end of the swing block 62 moves along the guide groove, when the partition baffle 3 starts to move away from the tail end, the swing block 62 will move along the recess structure, but it cannot directly return, for example, the swing block 62 can move along the circular arc part of the first recess structure towards the second recess structure, but the swing block 62 directly wants to return to the last recess structure and is blocked by the vertical side wall of the current recess structure, that is, the recess structure plays a positioning role on the swing block 62;
[0038] Until the swing block 62 moves to the last recess structure, the swing block 62 is lifted to reach the buffer window along the guide groove homing part 52, in order to facilitate the adjustment of the swing block 62, a handle is installed on the connecting plate and connected with the swing block, and a corresponding displacement groove is also arranged on the connecting plate.
[0039] The cooperation of the limiting guide rail strip 5 and the displacement piece 6 can gradually push the partition baffle 3 away when the tail end goods are gradually stacked, control the distance of the partition baffle 3 each time, avoid the tail end goods from being excessively squeezed, and also ensure that the partition baffle 3 will not easily lose the limit.
[0040] When the pallet goods are transported to the tail end, the partition baffle 3 does not need to be retracted, and the forklift can directly insert into the pallet from the interval between the tail end baffles. Compared with the conventional use of a cylinder or an extension rod to control the partition baffle 3, since the forklift will frequently collide with the partition baffle 3, plus the structure strength of the unfolded cylinder or extension rod is not large, which is easy to cause component damage. The limiting guide rail strip 5 and the displacement piece 6 are simple to process, the raw materials are easy to obtain, and the structure strength is sufficient. If the partition baffle 3 is retracted and then the pallet goods are unloaded, the conveying line needs to be stopped, and the goods on the pallet goods return path need to be emptied, so as to avoid the goods from being excessively squeezed during the return process, and an additional pushing force (manual or motor reverse rotation) is also needed to return the pallet goods, which is time-consuming and laborious.
