[0052] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. These embodiments are only used to illustrate this utility model and are not intended to limit it.

[0053] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0054] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0055] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0056] Figure 2 The image shown is a top view of the sorting module of this utility model. In the following description, it will be referred to as... Figure 2The attached diagram serves as a reference for direction. Figure 2 In the diagram, the direction perpendicular to the view paper and facing outwards is the upward direction, the direction perpendicular to the view paper and facing inwards is the downward direction, the direction along the view paper and upwards is the backward direction, the direction along the view paper and downwards is the forward direction, the direction along the view paper and to the right is the right direction, and the direction along the view paper and to the left is the left direction.

[0057] like Figure 1 and Figure 2 As shown, this utility model provides a sorting system, which includes a frame 4, a sorting mechanism, a bag feeding mechanism 5, and a discharge chute 6. The sorting mechanism includes multiple sorting modules 1 installed at intervals along the height direction (i.e., vertical direction) of the frame 4. Each sorting module 1 includes a closed track 2 and multiple sorting trolleys 3 installed on the closed track 2. Each sorting trolley 3 in each sorting module 1 is equipped with a travel drive source 34, and each sorting trolley 3 moves cyclically along the closed track 2 under the drive of its travel drive source 34. The bag feeding mechanism 5 is located at the loading station of the frame 4, including a bag feeding platform and a lifting and conveying module located between the bag feeding platform and the frame 4. The discharge chute 6 is installed on the frame 4, and is provided with multiple partitions to divide the discharge chute 6 into multiple discharge slots. Preferably, it also includes a receiving mechanism 7 arranged outside the discharge chute 6. The discharge chute 6 and the receiving mechanism 7 can be arranged along the extension direction of the closed track 2.

[0058] When the sorting system is working, the feeding station supplies items to the lifting and conveying module. The lifting and conveying module moves up and down to distribute the items to the sorting carts 3 in the sorting module 1 at different heights. Each sorting cart 3 moves from the loading station along the closed track 2 to any designated position under the drive of its own walking drive source 34. Then the sorting cart 3 delivers the items, so that the items enter the designated unloading slots. The items slide along the unloading slots to the receiving mechanism 7, completing one item delivery.

[0059] Compared to existing sorting systems using linear tracks, this invention employs a closed track, which increases the travel distance of the sorting trolley 3 within a limited installation space and increases the number of corresponding unloading slots. The sorting mechanism with multi-layer sorting modules and the package feeding mechanism with lifting and conveying modules expand the vertical capacity of the sorting system, thereby further increasing the number of unloading slots and improving the sorting capacity. At the same time, each sorting trolley 3 is driven by an independent drive source, making control more flexible and convenient, and ensuring stable delivery efficiency and accuracy.

[0060] The closed track 2 specifically includes a closed guide rail that is connected end to end and has no open end. The sorting trolley 3 can move infinitely along the closed track 2 and reach the same designated position without changing direction.

[0061] like Figure 2As shown, in a specific embodiment of this utility model, the closed track 2 includes a closed guide rail, the sorting trolley 3 is installed on the closed guide rail and is movably connected to the closed guide rail in the middle, and moves cyclically along the closed guide rail under the drive of its own walking drive source 34.

[0062] like Figure 3 As shown, in another specific embodiment of this utility model, the enclosed track 2 includes two enclosed guide rails of the same shape, arranged sequentially from the outside to the inside: an outer guide rail 21 on the outside and an inner guide rail 22 on the inside. The sorting trolley 3 is installed between the outer guide rail 21 and the inner guide rail 22, and moves cyclically along both the outer guide rail 21 and the inner guide rail 22 simultaneously under the drive of its own walking drive source 34. Compared to setting one enclosed guide rail, setting two enclosed guide rails helps to better support the sorting trolley 3, making the movement of the sorting trolley 3 more stable.

[0063] like Figure 4 and Figure 5 As shown, the sorting trolley 3 includes a trolley support 33, rollers rotatably mounted on both sides of the trolley support 33, and a conveyor belt 31 wound around the two rollers. One of the rollers is connected to a conveyor belt drive source 32, or is an electric roller. When the roller rotates, it can drive the conveyor belt 31 to move horizontally, thereby realizing the receiving or delivery of items.

[0064] The sorting trolley 3 also includes a drive wheel assembly and a driven wheel assembly 36 disposed at the bottom of the trolley support 33. The drive wheel assembly includes a drive wheel 341 that rotates under the drive of the travel drive source 34, a cantilever 331 hinged to the trolley support 33, and a limiting wheel 35 disposed at the bottom of the cantilever 331. The travel drive source 34 is mounted on the trolley support 33; the cantilever 331 and the trolley support 33 are connected by a spring 37. The axes of the drive wheel 341 and the limiting wheel 35 both extend in the vertical direction and are distributed on both sides along the moving direction of the sorting trolley 3, for contacting the side wall of the closed track 2. The arrangement of the cantilever 331 and the spring 37 provides a certain degree of flexibility for the steering of the sorting trolley 3, and the elastic force of the spring 37 ensures that the drive wheel 341 and the limiting wheel 35 are in close contact with the side wall of the closed track 2. The driven wheel assembly 36 includes a traveling wheel 361 and multiple guide wheels 362. The axis of the traveling wheel 361 extends horizontally and is used to travel on the top of the enclosed track 2. The axes of the guide wheels 362 extend vertically, and the multiple guide wheels 362 are distributed on both sides along the moving direction of the sorting cart 3 for contacting the side walls of the enclosed track 2. The conveyor belt drive source 32 and the traveling drive source 34 are specifically servo motors.

[0065] To prevent items from falling off the sorting trolley 3, preferably, the trolley support 33 further includes two baffles 332, which extend along the length of the conveyor belt 31 and are arranged on both sides of the conveyor belt 31 along the width of the conveyor belt 31, forming a first opening 381 and a second opening 382 between them and the two ends of the conveyor belt 31, respectively; it also includes a blocking part for blocking items placed on the conveyor belt 31 from passing through the first opening 381 and / or the second opening 382.

[0066] One embodiment of the blocking part includes a gate and a drive source. The drive source is located near the first opening 381 or the second opening 382 and is used to drive the gate to perform lifting or rotating movements. When the gate blocks the first opening 381 or the second opening 382, ​​the object will not fall off the conveyor belt 31.

[0067] Embodiment 2 of the blocking part includes multiple stops 733 spaced apart along the length of the conveyor belt 31. The stops 733 extend along the width of the conveyor belt 72, and their specific shapes are not limited, such as strips, plates, blocks, columns, or irregular shapes. When the sorting trolley 3 receives / delivers objects, the roller drives the conveyor belt 31 to move, so that one stop is located at the bottom of the conveyor belt 31 and the other stop is located at the top of the conveyor belt 31. The objects can pass smoothly through the first opening 381 / second opening 382 and enter or leave the conveyor belt 31. When the sorting trolley 3 transports objects, the roller drives the conveyor belt 31 to move in the opposite direction. At this time, both stops are located at the top of the conveyor belt 31, and the objects are located between the two stops. The movement of the objects along the length of the conveyor belt 31 is blocked by the stops, and they cannot fall down through the first opening 381 / second opening 382.

[0068] The shape of the closed track 2 is not limited; it can be a circular track or an irregular track.

[0069] like Figure 2 or Figure 3 As shown, the circular track is specifically shaped like a playground, comprising two straight segments 211 and two arc segments 212. The two straight segments 211 are arranged parallel to each other, and the two arc segments 212 are respectively located on the left and right sides of the two straight segments 211, connecting the ends of the two straight segments 211 on the same side. Those skilled in the art can also change the shape of the circular track as needed, such as making it circular, elliptical, or irregular.

[0070] like Figure 6-9 As shown, irregular orbits can be as follows: Figure 6 The L-shape shown, such as Figure 7 The U-shaped shape shown is as follows: Figure 8 The E-type shown or as Figure 9 The closed track shown has wavy segments.

[0071] Specifically, such as Figure 6 As shown, the L-shaped closed track 2 includes a first straight segment extending forward and backward and a second straight segment extending left and right. The packaging mechanism 5 is located at the connection between the first straight segment and the second straight segment. Multiple material discharge chutes 6 are located on the outside of the closed track 2 along the extension direction of the first straight segment and the second straight segment.

[0072] like Figure 7 As shown, the U-shaped closed track 2 includes four arc-shaped segments and four straight segments arranged sequentially from left to right: a first straight segment, a second straight segment, a third straight segment, and a fourth straight segment. All four straight segments extend in the front-to-back direction, with the first and fourth straight segments having the same length, the second and third straight segments having the same length, and the first straight segment being longer than the second. The rear ends of the first and fourth straight segments are connected by the first arc-shaped segment, the front ends of the first and second straight segments are connected by the second arc-shaped segment, the rear ends of the second and third straight segments are connected by the third arc-shaped segment, and the front ends of the third and fourth straight segments are connected by the fourth arc-shaped segment. A bag-feeding mechanism 5 is provided on the outer side of each of the first and fourth straight segments, and a material discharge chute 6 is provided on the outer side of the closed track 2 along the extending directions of the first, second, third, and fourth straight segments.

[0073] like Figure 8 As shown, the E-type closed track 2 includes a first section extending in the front-to-back direction, six second sections spaced apart in the front-to-back direction, and five arc-shaped sections for connecting the six second sections end to end. The second sections extend in the left-to-right direction, with the foremost and rightmost second sections connected to the front and rear ends of the first section, respectively. A bag-feeding mechanism 5 is provided on the outside of the first section and the foremost and rightmost second sections, respectively. A material discharge chute 6 is provided on the outside of the closed track 2 along the extending directions of the first section and the six second sections.

[0074] like Figure 9 As shown, the closed track 2 with wave segments is based on the E-type closed track 2 with the addition of the second segment and the number of arc segments.

[0075] The aforementioned irregularly shaped tracks can better adapt to the conditions of different installation sites, avoid existing equipment in the installation site, make full use of the installation space, and increase the sorting capacity of the sorting system.

[0076] In each sorting module 1, the number of sorting trolleys 3 on the closed track 2 is not limited, and those skilled in the art can increase or decrease them according to the length of the closed track 2 and the requirements of sorting efficiency.

[0077] The feeding platform includes two feeding rollers and a feeding conveyor belt disposed between the two feeding rollers. The feeding conveyor belt rotates continuously under the drive of a motor, which can transport objects in the direction of the lifting and conveying module.

[0078] The lifting and conveying module includes a fixed frame, which is rectangular in shape. A lifting drive source is located at the top of the frame, driving a lifting synchronous shaft to rotate. Two driving wheels are mounted on the lifting synchronous shaft, and two driven wheels are located at the bottom of the fixed frame. A lifting transmission component is positioned between the driving and driven wheels on the same side, connecting the two transmission components to the lifting frame. A lifting trolley is fixedly connected within the lifting frame. The lifting trolley has a structure similar to a sorting trolley, including a trolley support, two rollers mounted on the support, and a conveyor belt positioned between the rollers. When the lifting drive source drives the lifting synchronous shaft to rotate, it simultaneously moves the lifting frame and the lifting trolley between the two transmission components in a lifting motion.

[0079] When the package supply mechanism 5 is working, the package supply conveyor belt supplies items to the lifting trolley. The lifting trolley moves up and down and distributes the items to the sorting trolleys 3 in the sorting module 1 located at different heights via the trolley conveyor belt.

[0080] The aforementioned lifting drive source can be a stepper motor or a servo motor. The aforementioned lifting drive wheel and lifting driven wheel are selected from pulleys or sprockets, and the lifting transmission components can be transmission components such as cables, ropes, belts, or chains that can convert the rotational motion of the wheels into translational motion.

[0081] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
