Description

Technical Field

[0001] This invention relates to the field of logistics sorting technology, and more particularly to a logistics warehousing and sorting structure. Background Technology

[0002] In the fields of modern logistics, express delivery and e-commerce warehousing, automated sorting systems are core equipment. Their efficiency and reliability directly determine the sorting capacity of the entire logistics system. Traditional automated sorting technologies, such as cross belt sorters, slider sorters and swing wheel sorters, are not effective enough for sorting small soft packages and heavy boxes.

[0003] In the prior art, such as the patent with publication number CN117181610A, a smart logistics warehousing and sorting equipment is disclosed, including a sorting base plate, and a rectangular opening is opened on one side of the top of the sorting base plate. Sorting rotating shafts are rotatably installed at the front and rear ends of the inner wall of the rectangular opening of the sorting base plate, and the other ends of the two sorting rotating shafts are fan-shaped and dispersed. A base block is welded and fixed to the middle of the inner wall of the rectangular opening of the sorting base plate, and a bearing ring is installed on the other side of the base block. A rotatable sorting rotating shaft is installed on the inner wall of the bearing ring. The other end of the sorting rotating shaft is fixed to the other side of the inner wall of the rectangular opening of the sorting base plate through the bearing ring. A sorting mechanism is provided on one side of the bottom of the sorting base plate.

[0004] The above structure utilizes a sorting rotating shaft and a fan-shaped sorting rotating shaft to disperse boxes of different sizes. Boxes of different sizes will fall at different positions onto the sorting conveyor below for sorting. However, because the sorting methods for light and small soft packages and heavy boxes are different, they are prone to deflection, rolling or jamming on the sorting path, and the sorting process is not smooth enough. Summary of the Invention

[0005] In view of this, the purpose of this invention is to propose a logistics warehousing and sorting structure to solve the problem that due to the different sorting methods for light and small soft packages and heavy boxes, deflection, rolling or jamming can easily occur on the sorting path, resulting in an unsmooth sorting process.

[0006] Based on the above objectives, the present invention provides a logistics warehousing and sorting structure, including a roller body and a transverse array of transfer rollers inside the roller body. Multiple sets of transfer rollers are rotated by external drive. A discharge hopper is fixedly installed at one end of the roller body, and an inclined plate is fixedly installed on one side of the roller body. Two sorting conveyor tables are provided below the inclined plate. The sorting conveyor tables are used to transport sorted items. A side plate platform is fixedly installed on the roller machine body, and photoelectric sensor one and photoelectric sensor two are respectively installed on one side of the side plate platform; The side plate platform has a slot inside, and multiple sets of lateral finger pieces are arranged inside the slot, with the lateral finger pieces corresponding to the transmission rollers. Bottom finger components are provided between multiple sets of transmission rollers. The bottom finger components are staggered with the transmission rollers. The bottom finger components are movably installed on the inner wall of the roller body. A control structure is connected between the bottom finger components and the side finger components. The control structure is electrically connected to photoelectric sensor one and photoelectric sensor two, respectively. The control structure is used to drive the multiple sets of bottom finger components and the multiple sets of side finger components to push different objects to the inclined plate.

[0007] Preferably, a long rod and a short rod are sequentially installed on one side of the side panel platform, and a crossbar is fixedly installed on both the long rod and the short rod. A photoelectric sensor one and a photoelectric sensor two are respectively provided on one side of the long rod and the short rod. Preferably, the bottom finger component includes a swing rod movably mounted on the inner wall of the roller mill, and multiple sets of sliding wheels are rotatably mounted inside the swing rod.

[0008] Preferably, the lateral lever component includes multiple sets of telescopic cylinder one and telescopic cylinder two fixedly installed inside the slot, and the output ends of telescopic cylinder one and telescopic cylinder two are fixedly connected to levers.

[0009] Preferably, the control structure includes a long-stroke cylinder and a short-stroke cylinder fixedly installed inside the roller mill body. The long-stroke cylinder is connected to a photoelectric sensor one, and the short-stroke cylinder is connected to a photoelectric sensor two. The output end of the long-stroke cylinder is fixedly connected to four sets of swing rods, which form a large box area. The output end of the short-stroke cylinder is fixedly connected to the other three sets of swing rods, which form a small box area. Multiple sets of spring telescopic rods are provided at the bottom of the large box area. The side of the spring telescopic rod away from the long-stroke cylinder is provided with an elastic rod. An inclined block is fixedly installed at the end of the elastic rod. A bracket is fixedly installed on the inner wall of the roller machine body. A contact switch corresponding to the inclined block is fixedly installed on the bracket. The contact switch is connected to the telescopic cylinder. Multiple sets of spring telescopic rods are provided at the bottom of the small box area. The spring telescopic rods are located near the side of the short-stroke cylinder, and a pressing head is fixedly installed on one side of the spring telescopic rods. A contact switch is provided above the pressing head. The contact switch is installed inside the roller machine body and is connected to the telescopic cylinder.

[0010] Preferably, the two sorting and conveying stations correspond to the large box area and the small box area respectively, the support is an L-shaped structure, and the inclined blocks are mirror images of the upper and lower sides of the elastic rod.

[0011] Preferably, at least four sets of the first telescopic cylinder and at least three sets of the second telescopic cylinder are provided.

[0012] Preferably, at least eight sets of sliding wheels are provided, and the cross-sectional height of the sliding wheels is smaller than the cross-sectional height of the transmission rollers.

[0013] The beneficial effects of this invention are: Items of different sizes are transported by the conveyor rollers on the roller machine body. When a light and small soft package and a heavy box pass by the photoelectric sensor one at the same time, the heavy box will block the photoelectric sensor one. The bottom finger piece under the target box will lift up synchronously, briefly lifting the box away from the conveyor roller. At this time, the lifted bottom finger piece can tilt to the side as a whole. After being lifted up, the side finger piece will give the box a lateral force, sending it into the inclined plate. After completion, the swing rod will descend and reset. Small, lightweight soft packages may obstruct the photoelectric sensor. The control structure pushes one end of the bottom dial finger upward a small distance, causing the lateral dial finger to activate. The lateral dial finger performs the main pushing action, easily pushing the box towards the ramp. The ramp then transfers boxes of different sizes to different sorting conveyor stations. If there are smaller packages, they are directly fed into the discharge hopper via the conveyor rollers. The entire process sorts small, lightweight soft packages and heavy boxes, effectively guiding and controlling the items to prevent them from deviating, rolling, or getting stuck on the sorting path, ensuring a smooth and continuous sorting process.

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a logistics warehousing and sorting structure includes a roller body 1 and a transverse array of transfer rollers 2 inside the roller body 1. Multiple sets of transfer rollers 2 are rotated by external drive. A discharge hopper 5 is fixedly installed at one end of the roller body 1, and an inclined plate 3 is fixedly installed on one side of the roller body 1. Two sorting transfer tables 4 are arranged below the inclined plate 3. The sorting transfer tables 4 are used to transfer sorted items. A side plate platform 9 is fixedly installed on the roller machine body 1. A long rod 10 and a short rod 11 are installed sequentially on one side of the side plate platform 9. A crossbar 12 is fixedly installed on both the long rod 10 and the short rod 11. A photoelectric sensor 13 and a photoelectric sensor 2 14 are respectively installed on one side of the long rod 10 and the short rod 11. The side plate platform 9 has a slot 72 inside, and multiple sets of lateral finger pieces 7 are arranged inside the slot 72, which correspond to the transmission roller 2. Bottom finger pieces 6 are provided between multiple sets of transmission rollers 2. The bottom finger pieces 6 and the transmission rollers 2 are staggered. The bottom finger pieces 6 are movably installed on the inner wall of the roller body 1. A control structure 8 is connected between the bottom finger pieces 6 and the side finger pieces 7. The control structure 8 is electrically connected to photoelectric sensor 13 and photoelectric sensor 2 14, respectively. The control structure 8 is used to drive the multiple sets of bottom finger pieces 6 and the multiple sets of side finger pieces 7 to push different objects to the inclined plate 3.

[0019] In this embodiment, objects of different sizes are transported by the conveyor rollers 2 on the roller machine body 1. They first pass through the large box area. Using the photoelectric sensor 13 on the long rod 10, when a light soft bag and a heavy box pass by the photoelectric sensor 13 at the same time, the heavy box will block the photoelectric sensor 13. The bottom finger 6 under the target box will be lifted upwards in sync, briefly lifting the box away from the conveyor roller 2. At this time, the lifted bottom finger 6 can tilt to the side as a whole. In the lifted state, the side finger 7 gives the box a lateral force and sends it into the inclined plate 3. After completion, the swing rod 61 descends and resets. After passing through the small box area, the photoelectric sensor 14 on the short rod 11 is used. However, the light and small soft package will block the photoelectric sensor 14. The control structure 8 pushes one end of the bottom finger 6 to move upward a small distance, and the side finger 7 starts to move. The side finger 7 performs the main pushing action, easily pushing the box towards the inclined plate 3. The inclined plate 3 transfers the large and small boxes to different sorting conveyor tables 4. If there are smaller packages, they directly enter the discharge hopper 5 through the conveyor roller 2. The overall sorting effect of light and small soft packages and heavy boxes achieves effective guidance and control of the items, preventing them from deflecting, rolling or getting stuck on the sorting path, and ensuring the smoothness and continuity of the sorting process.

[0020] As one implementation method, such as Figure 4 , Figure 5 As shown, the bottom finger component 6 includes a swing rod 61 movably mounted on the inner wall of the roller body 1, and multiple sets of sliding wheels 62 are rotatably mounted inside the swing rod 61.

[0021] The sliding wheel 62 is provided with at least eight sets, and the cross-sectional height of the sliding wheel 62 is less than the cross-sectional height of the transmission roller 2.

[0022] In this embodiment, the box is normally conveyed on the conveyor roller 2. When sorting is required, the swing rod 61 below the target box is simultaneously lifted upward, briefly lifting the box away from the conveyor roller 2. At this time, the lifted swing rod 61 can tilt to the side as a whole, and the sliding wheel 62 increases the inertia of the tilted box. In the lifted state, a lateral force is applied to the box, sending it into the inclined plate 3. After completion, the swing rod 61 is lowered and reset.

[0023] As one implementation method, such as Figure 2 , Figure 3 , Figure 4 As shown, the lateral lever 7 includes multiple sets of telescopic cylinder 1 73 and telescopic cylinder 2 74 fixedly installed inside the slot 72. The output ends of telescopic cylinder 1 73 and telescopic cylinder 2 74 are all fixedly connected to levers 75.

[0024] Among them, telescopic cylinder 1 73 is provided with at least four sets, and telescopic cylinder 2 74 is provided with at least three sets.

[0025] In this embodiment, when the box needs to be sorted, the lateral finger 7 on one side extends and pushes the object laterally to change its path. The telescopic cylinder 1 73 corresponds to the large box and the telescopic cylinder 2 74 corresponds to the small box, sliding into the inclined plate 3 located on the side.

[0026] As one implementation method, such as Figure 3 , Figure 4 , Figure 5 As shown, the control structure 8 includes a long-stroke cylinder 81 and a short-stroke cylinder 82 fixedly installed inside the roller body 1. The long-stroke cylinder 81 is connected to a photoelectric sensor 13, and the short-stroke cylinder 82 is connected to a photoelectric sensor 14. The output end of the long-stroke cylinder 81 is fixedly connected to four sets of swing rods 61, which form a large box area. The output end of the short-stroke cylinder 82 is fixedly connected to the other three sets of swing rods 61, which form a small box area. Multiple sets of spring telescopic rods 86 are provided at the bottom of the large box area. The side of the spring telescopic rod 86 away from the long-stroke cylinder 81 is fixedly equipped with an elastic rod 89. An inclined block 891 is fixedly installed at the end of the elastic rod 89. A bracket 87 is fixedly installed on the inner wall of the roller machine body 1. A contact switch 85 corresponding to the inclined block 891 is fixedly installed on the bracket 87. The contact switch 85 is connected to the telescopic cylinder 73. Multiple sets of spring telescopic rods 83 are provided at the bottom of the small box area. The spring telescopic rods 83 are located near the side of the short-stroke cylinder 82, and a pressing head 84 is fixedly installed on one side of the spring telescopic rods 83. A contact switch 85 is provided above the pressing head 84. The contact switch 85 is installed inside the roller machine body 1 and is connected to the telescopic cylinder 74.

[0027] In this embodiment, the large box body blocks the photoelectric sensor 13, which activates the long-stroke cylinder 81 in the control structure 8, pushing one end of the bottom finger 6 to move upward. The bottom finger 6 lifts the large box body and moves it laterally towards the inclined plate 3. When the box body is moved to the vicinity of the grid edge by the bottom finger 6, and when the bottom finger 6 returns to its original position downward, the lateral finger 7 starts to move, giving the box body a pushing force to ensure that it can slide completely into the inclined plate 3 by inertia without getting stuck at the edge of the inclined plate 3. The action ends. The small, soft bag will block the photoelectric sensor 14, activating the short-stroke cylinder 82 in the control structure 8, pushing one end of the bottom toggle 6 upward a small distance. The tilted bottom toggle 6 slightly reduces the friction between the soft bag and the conveyor belt surface. At this time, the bottom spring telescopic rod 83 causes the pressing head 84 to contact the contact switch 85, and the side toggle 7 begins to move. While maintaining the bottom toggle 6 to provide stable support, the side toggle 7 performs the main pushing action, easily pushing the box towards the inclined plate 3.

[0028] As one implementation method, such as Figure 4 , Figure 5 As shown, the two sorting and conveying stations 4 correspond to the large box area and the small box area respectively. The support 87 has an L-shaped structure, and the inclined blocks 891 are mirrored on the upper and lower sides of the elastic rod 89.

[0029] In this embodiment, as the bottom toggle 6 moves upward, the bottom spring telescopic rod 86 moves upward at the same time. The elastic rod 89 and the inclined block 891 move upward and cannot contact the contact switch 88. When the bottom toggle 6 returns to its original position, the side toggle 7 starts to move. For large boxes, the bottom toggle 6 and the side toggle 7 move sequentially and overlap at the end, ensuring the final success rate of sorting.

[0030] Working principle: During use, objects of different sizes are transported by the conveyor rollers 2 on the roller conveyor body 1. They first pass through the large box area. Using the photoelectric sensor 13 on the long rod 10, when a small, light package and a large box pass by the photoelectric sensor 13 simultaneously, the large box blocks the photoelectric sensor 13, activating the long-stroke cylinder 81 in the control structure 8. This pushes one end of the bottom lever 6 upwards, lifting the large box and moving it laterally towards the inclined plate 3. As the box is moved by the bottom lever 6... When the box moves to the vicinity of the grid edge, the bottom toggle 6 moves upward, and the bottom spring telescopic rod 86 moves upward at the same time. The elastic rod 89 and the inclined block 891 move upward and cannot contact the contact switch 88. When the bottom toggle 6 returns to its original position, the side toggle 7 starts to move. When the box is slightly deviated at an angle during the bottom transportation process, the side toggle 7 can push it back to the correct position and at the same time give the box a continuous pushing force. It slides completely into the inclined plate 3 by inertia and will not get stuck on the edge of the inclined plate 3. The action ends and all toggle fingers return to their original positions. After passing through the small box area, using the photoelectric sensor 14 on the short rod 11, if there are smaller packaged items, they will directly enter the discharge hopper 5 through the transfer roller 2. However, light and small soft packages will block the photoelectric sensor 14, activating the short-stroke cylinder 82 in the control structure 8, pushing one end of the bottom finger 6 upward a small distance. The tilted bottom finger 6 slightly reduces the friction between the soft package and the conveyor belt surface. At this time, the bottom spring telescopic rod 83 causes the pressing head 84 to contact the contact switch 85, and the side finger 7 starts to move. While maintaining the bottom finger 6 to provide stable support, the side finger 7 performs the main pushing action, easily pushing the box towards the inclined plate 3. The inclined plate 3 transfers the large and small boxes to different sorting conveyor tables 4, which improves the sorting effect of light and small soft packages and heavy boxes, realizes effective guidance and control of items, prevents them from deflecting, rolling or getting stuck on the sorting path, and ensures the smoothness and continuity of the sorting process.
