Description

Technical Field

[0001] The present invention relates to the technical field of transportation-related fields, and in particular to a mechanism for preventing upper and lower transition conveyor parts from falling off on a linear sorting platform for express mail. Background Art

[0002] With the rapid development of the Internet, the number of express deliveries has increased dramatically. Express mail is usually sorted and transported in a straight line using conveyor rollers or conveyor belts. Regardless of whether conveyor rollers or conveyor belts are used, the mail is placed above the conveyor rollers or conveyor belts when it is being transported. The mail can only be transported on planes at the same height. At a time when the volume of express deliveries is increasing dramatically, linear sorting and transport of mail on the same plane is not suitable, and three-dimensional transport, i.e. upper and lower layer transport, is required. Usually, two planes with a height difference need to be transported through a lifting mechanism. The lifting mechanism works once, rising to align with the high-level conveyor plane and descending to align with the low-level conveyor plane. This not only makes the mechanism complex and the transport efficiency low, but also requires multiple moves of the mail during transport, increasing the chance of damage. Summary of the Invention

[0003] In order to overcome the defects of the prior art, the present invention provides a balancing mechanism for a linear sorting device that keeps mail from falling during the upper and lower transitions, reduces the probability of mail damage caused by the use of a lifting mechanism, reduces the area occupied by mail transportation, and improves transmission efficiency.

[0004] To achieve the above objectives, the present invention employs the following technical solution: a balancing mechanism for a linear sorting device that prevents mail from falling during its transition from one level to the next. The mechanism comprises a frame and a trolley. The frame is connected to a rotating wheel via a main shaft. The trolley is fixedly connected to a trolley central axis, which moves along the outer circumference of the rotating wheel. The trolley central axis is fixedly connected to a connecting block. The rotating wheel is fixedly connected to a balancing wheel. The main shaft is sleeved with a balancing ring, which is connected to a plurality of vertical balancers. The vertical balancers are connected to the rotating wheel and abutted against the connecting block. The trolley passes through a circular rotating wheel to keep the platform parallel to the horizontal plane. The trolley-loaded mail does not fall, achieving continuous, connected transport of mail between the upper and lower layers of linear sorting, resulting in high transmission efficiency. This reduces the movement of mail and reduces the chance of damage.

[0005] Preferably, the vertical balancer includes: a strip-shaped flat vertical plate, an upper shaft and a lower shaft fixed to the vertical plate, a connecting plate, and a balancing block fixed to the connecting plate, the lower shaft, the vertical plate, and the upper shaft are connected in a Z shape, the upper shaft, the connecting plate, and the balancing block are connected in a Z shape, and the surface of the balancing block is perpendicular to the surface of the vertical plate.

[0006] Preferably, the balance ring is annular, the lower shaft is rotatably connected to the annular ring of the balance ring, the upper shaft is rotatably connected to the balance wheel near the edge surface, and the vertical plate and the balance block are located on both sides of the balance wheel.

[0007] Preferably, the balancing block is in contact with the connecting block, and the center of the balancing ring is offset downward from the center of the rotating wheel due to its own weight.

[0008] Preferably, the trolley is a rectangular platform, and the trolley center axis is located at the center axis of the trolley platform.

[0009] As a preferred method, the connection between the trolley and the runner is as follows:

[0010] 1. The middle shaft of the trolley is connected with a chain, the rotating wheel is a sprocket, and the chain is engaged with the sprocket.

[0011] 2. The center shaft of the trolley is connected with a toothed belt, the runner is a gear, and the toothed belt is meshed with the gear.

[0012] The present invention has the following beneficial effects: the trolley, via its circular rotating wheels, achieves linear sorting and continuous conveying of mail between upper and lower levels, reducing mail handling and improving delivery efficiency. The linear sorting and conveying transition between upper and lower levels occupies a small footprint, lowering operational costs. The trolley platform remains parallel to the horizontal plane during the transition, ensuring that loaded mail does not fall, reducing the risk of damage and improving the quality of delivered mail.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1:

[0022] like Figure 1-6As shown, a platform conveying mechanism includes a frame 1 and a trolley 5. The trolley 5 is a rectangular platform. Raised stop bars are provided on the upper surface of the trolley 5. The stop bars are arranged around the upper surface of the trolley 5. The trolley 5 is fixedly connected to a trolley central axis 52. The trolley central axis 52 is located on the central axis of the trolley 5 platform. Both ends of the trolley central axis 52 extend outside the trolley 5 platform. The trolley central axis 52 is fixedly connected to a connecting block 51. The connecting block 51 is rectangular and fixed to one end of the trolley central axis 52. The connecting block 51 is perpendicular to the horizontal plane.

[0023] The frame 1 is a rectangular frame. Frame 1 is rotatably connected to a runner 6 via a main shaft. The main shaft is located in the center of frame 1 and parallel to the horizontal plane. The main shaft and frame 1 are connected via a bearing. The runner 6 is connected to the main shaft via a key. The runner 6 is fixedly connected to the main shaft. The balance wheel 4 is disc-shaped and fixed coaxially with the runner 6.

[0024] The main shaft is sleeved with a balancing ring 2. The balancing ring 2 is annular. The annular surface of the balancing ring 2 is parallel to the surface of the rotating wheel 6. There is a gap between the balancing wheel 4 and the rotating wheel 6. The connecting block 51 falls within this gap.

[0025] The gimbal 2 is connected to several vertical stabilizers 3. The vertical stabilizers 3 include a lower shaft 31, vertical plates 32, an upper shaft 33, a connecting plate 34, and a balancing weight 35. The vertical plates 32 are flat, strip-shaped plates. The larger surface area is the vertical plate 32. One end of the lower shaft 31 and the upper shaft 33 are fixed to the ends of the vertical plates 32, respectively, while the other ends are suspended. The lower shaft 31, vertical plates 32, and upper shaft 33 are connected to form a Z-shape. The connecting plate 34 and balancing weight 35 are rectangular plates. The larger surface area is the connecting plate 34 and balancing weight 35. The side surfaces of the connecting plate 34 are fixed to the surfaces of the balancing weight 35 near their edges. The suspended end of the upper shaft 33 is fixed to the surface of the connecting plate 34. The upper shaft 33, connecting plate 34, and balancing weight 35 are connected to form a Z-shape. The vertical plates 32 and connecting plates 34 are parallel and spaced apart. The surface of the balancing weight 35 is perpendicular to the surface of the vertical plates 32.

[0026] The suspended end of the lower shaft 31 is connected to the balancing ring 2 via a bearing. The lower shaft 31 is perpendicular to the annular surface of the balancing ring 2. The balancing ring 2 is parallel to the surface of the vertical plate 32, with a gap therebetween. The balancing wheel 4 is provided with a bearing near the edge, and the upper shaft 33 is located between the vertical plate 32 and the connecting plate 34 and is connected to the bearing. The vertical plate 32 and the connecting plate 34 are located on either side of the balancing wheel 4, with gaps between the two surfaces of the balancing wheel 4. The upper shaft 33 is rotationally connected to the balancing wheel 4 near the edge surface. The upper shaft 33 is perpendicular to the surface of the balancing wheel 4. The balancing weight 35 falls in the gap between the balancing wheel 4 and the rotating wheel 6.

[0027] The number of vertical balancers 3 is related to the distance between the center axes 51 of adjacent trolleys 5. The vertical balancers 3 are evenly distributed near the edge of the rotating wheel 6, and the arc length between two adjacent vertical balancers 3 is equal to the distance between the center axes 51 of adjacent trolleys 5. The weight of the balancing ring 2 itself is greater than the sum of the weight of the trolley 5 and the weight of the mail loaded on the trolley 5. The balancing ring 2 relies on the vertical balancers 3 connected to the balance wheel 4 to offset its own weight and is suspended on the side of the balancing ring 2. Due to the weight of the balancing ring 2, the center of the ring is offset downward from the center of the rotating wheel 6. The plane of the balancing block 35 remains vertical and horizontal.

[0028] The trolley's central shaft 52 is connected to a chain. There is a pair of chains, located on either side of the trolley 5. The ends of the trolley's central shaft 52 extending from either side of the trolley 5 are respectively connected to a sleeve in each of the two chains. The trolley's central shaft 52 passes through one end face of the sleeve and is fixedly connected to the connecting block 51. The rotating wheel 6 is a sprocket. There are two sprockets, one on each side of the trolley 5. One sprocket is fixed to the balance wheel 4. The chain and sprocket engage. The rotation of the sprocket drives the sprocket to move horizontally, and the trolley 5 also moves horizontally. When the chain connected to the trolley's central shaft 52 engages the sprocket, the balance weight 35 abuts the connecting block 51. The weight of the balance ring 2 itself is greater than the weight of the trolley 5 plus the weight of the mail loaded on the trolley 5. The balance weight 35 maintains a vertical horizontal plane. The balance weight 35 forces the connecting block 51 to maintain a vertical horizontal plane. The trolley's central shaft 52 cannot rotate. As the chain and sprocket engage, the trolley's central shaft 52 moves along the circumference of the sprocket. When trolley 5 passes through sprocket arc, the plane of trolley 5 platform remains parallel to the horizontal plane always. Like this, the mail of trolley 5 load is moved from upper layer to lower layer or from lower layer to upper layer, always on trolley 5 platform, can not fall.

[0029] Example 2:

[0030] In order to make the structure lightweight and reduce noise and oil pollution, the trolley central shaft 52 is connected to a toothed belt. There is a pair of toothed belts located on both sides of the trolley 5. The ends of the trolley central shaft 52 extending from both sides of the trolley 5 are fixed to the planes of the two toothed belts respectively. One end extends out of the toothed belt and the other side is fixed to the connecting block 51. The runner 6 is a gear. There are two gears located on both sides of the trolley 5. The gear on one side is fixed to the balance wheel 4. The toothed belt meshes with the gear. The gear rotates, driving the toothed belt to move horizontally, and the trolley 5 also moves horizontally. When the teeth fixed to the trolley central shaft 52 mesh with the gear, the balance block 35 is in contact with the connecting block 51. Due to its own weight, the balance ring 2 keeps the balance block 35 in a vertical horizontal plane. The balance block 35 forces the connecting block 51 to maintain a vertical horizontal plane. The trolley central shaft 52 cannot rotate. The trolley central shaft 52 moves along the outer circumference of the gear as the toothed belt meshes with the gear. When the trolley 5 passes through the gear arc, the plane of the trolley 5 platform always remains parallel to the horizontal plane. The mails loaded by the trolley 5 are moved from the upper layer to the lower layer or from the lower layer to the upper layer, and they are always on the trolley 5 platform and will not fall.
