Description

Technical Field

[0001] This utility model relates to the field of object sorting technology, and in particular to a sorting system. Background Technology

[0002] The working principle of the existing reciprocating sorting machine is as follows: After the object is automatically scanned, it is transported to the sorting trolley via the conveyor line. The sorting trolley transports the object to the designated slot for delivery, and then returns to the origin to pick up the next object, and so on in a reciprocating cycle.

[0003] Due to mechanical limitations, the travel distance of each sorting cart is finite and cannot be extended indefinitely. Therefore, the number of corresponding sorting slots is limited, resulting in a limited sorting capacity. However, faced with ever-increasing logistics and transportation demands, existing sorting machines need continuous expansion to increase their total sorting capacity. How to meet these expansion requirements based on existing sorting machines is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0014] Preferably, the feeding station includes a feeding frame with a feeding area and multiple sets of conveying components assembled in the feeding area. Each set of conveying components includes a conveying drive source, a pair of support rollers, and a conveyor belt connected to the outer periphery of the pair of support rollers. The support rollers are rotatably supported in the feeding frame and are connected to the conveying drive source. A triangular area is formed between two adjacent sets of conveying components.

[0015] Preferably, the support roller is a small-diameter roller with a diameter of no more than 40 mm.

[0079] 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.

[0080] 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," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used 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. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0081] 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 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.

[0082] Furthermore, in the description of this utility model, unless otherwise stated, "multiple" or "multiple groups" means two or more.

[0083] Figure 1 The image shown is a top view of a sorting system embodiment one. In the following description, it will be referred to as... Figure 1 The attached diagram serves as a reference for direction. Figure 1 In the diagram, the length direction of the translation track 1 is defined as the left-right direction, and the sorting mechanism 4 is located to the right of the package feeding mechanism 3; the width direction of the translation track 1 is defined as the front-back direction, and the sorting lifting unit 8 is located in front of the translation track 1; the height direction of the frame 2 is defined as the up-down direction, where the direction perpendicular to the paper and outward is the up direction.

[0084] like Figure 1-3 As shown, this utility model provides a sorting system, which includes a translation track 1, a package feeding mechanism 3 and a plurality of sorting mechanisms 4 arranged along the extension direction of the translation track 1.

[0085] The package feeding mechanism 3 includes a package feeding platform 31 and a package feeding assembly. The package feeding assembly includes a package feeding trolley 33 and a package feeding transmission unit 34 for driving the package feeding trolley 33 to move along the translation track 1; the package feeding platform 31 is used to transport items to the package feeding trolley 33.

[0086] The sorting mechanism 4 includes a sorting assembly, which comprises a sorting trolley 5, a sorting transmission unit 9, a transfer unit 6, and a receiving unit 7. The sorting trolley 5 moves along the translation track 1 under the drive of the sorting transmission unit 9. The transfer unit 6 and the receiving unit 7 are arranged sequentially along the extension direction of the translation track 1. The receiving unit 7 includes a row of material drop chutes and a row of material receiving frames arranged sequentially from the inside to the outside along the width direction of the translation track 1. The specific number of material drop chutes in each row and the specific number of material receiving frames in each row can be set as needed. Preferably, a row of material drop chutes and a row of material receiving frames are provided on each side of the translation track 1 along its horizontal width direction.

[0087] The bag-feeding trolley 33 can reciprocate along the translation track 1 between the bag-feeding platform 31 and the transfer unit 6 of the sorting mechanism 4 adjacent to the bag-feeding mechanism 3; the sorting trolley 5 can reciprocate along the translation track 1 between the transfer units 6 of two adjacent sorting mechanisms 4, or between the transfer unit 6 and the receiving unit 7 of the same sorting mechanism 4. The bag-feeding trolley 33, the sorting trolley 5, and the transfer unit 6 all include a conveyor belt that can transport items along the horizontal width direction of the translation track 1.

[0088] During operation, the package feeding trolley 33 can transport the items received from the package feeding station 31 to the adjacent transfer unit 6. Then, the sorting trolleys 5 in one or more sorting mechanisms 4 work to transport the items to the corresponding unloading chute through direct or relay transmission. Then, the conveyor belt of the sorting trolley 5 moves, causing the items to enter the corresponding unloading chute. The items slide down the unloading chute and enter the receiving frame, completing one item delivery.

[0089] As can be seen from the above, this utility model can adjust the number of sorting mechanisms 4 according to the preset sorting volume, thereby increasing the number of receiving units 7 and achieving capacity expansion. At the same time, the items provided by the feeding mechanism 3 can be transferred to the receiving unit 7, which is farther away from the feeding mechanism 3, through the relay transmission of the sorting trolleys 5 of multiple sorting mechanisms 4, thus breaking through the limitation of the single sorting transmission unit 9 on the movement stroke of the sorting trolley 5 and meeting the capacity expansion requirements.

[0090] Figure 1 The diagram shows an embodiment of the sorting system of this utility model, wherein the translation track 1 is in a straight line shape, and multiple sorting mechanisms 4 are arranged on one side of the package feeding mechanism 3 along the extension direction of the translation track 1. The following is in conjunction with... Figure 1 Detailed explanation of the working principle of this utility model's sorting system:

[0091] Example 1 includes three sorting mechanisms 4 located to the right of the bag supply mechanism 3, namely, a first sorting mechanism 41, a second sorting mechanism 42, and a third sorting mechanism 43, arranged from closest to furthest from the bag supply mechanism 3. The first sorting mechanism 41 includes a first sorting component, which comprises a first sorting trolley 51, a first sorting transmission unit 91, a first transfer unit 61, and a first receiving unit 71. The second sorting mechanism 42 includes a second sorting component, which comprises a second sorting trolley 52, a second sorting transmission unit 92, a second transfer unit 62, and a second receiving unit 72. The third sorting mechanism 43 includes a third sorting component, which comprises a third sorting trolley 53, a third sorting transmission unit 93, a third transfer unit 63, and a third receiving unit 73.

[0092] In each sorting mechanism 4, the transfer unit 6 is located on the side closer to the packaging mechanism 3, and the receiving unit 7 is located on the side farther away from the packaging mechanism 3. Those skilled in the art can also adjust the relative positions of the transfer unit 6 and the receiving unit 7 as needed, such as placing the receiving unit 7 on the side closer to the packaging mechanism 3.

[0093] After receiving the item from the supply station 31, the supply trolley 33 transports the item to the first transfer unit 61 of the first sorting mechanism 41 adjacent to the supply mechanism 3.

[0094] When an object needs to be delivered to the first receiving unit 71, the first sorting trolley 51 moves to the first transfer unit 61 to receive the object under the drive of the first sorting transmission unit 91, and then moves to the first receiving unit 71 for delivery.

[0095] When an item needs to be delivered to the second receiving unit 72, the first sorting trolley 51 receives the item from the first transfer unit 61 and then transports the item to the second transfer unit 62. The second sorting trolley 52, driven by the second sorting transmission unit 92, first moves to the second transfer unit 62 to receive the item, and then moves to the second receiving unit 72 to deliver it.

[0096] When an item needs to be delivered to the third receiving unit 73, the first sorting trolley 51 receives the item from the first transfer unit 61 and transports it to the second transfer unit 62. The second sorting trolley 52 then transports the item from the second transfer unit 62 to the third transfer unit 63. Driven by the third sorting transmission unit 93, the third sorting trolley 53 first moves to the third transfer unit 63 to receive the item, and then moves to the third receiving unit 73 for delivery.

[0097] Those skilled in the art can increase or decrease the number of sorting mechanisms 4 based on Embodiment 1 as needed. The working principle of relay transmission between a larger number of sorting mechanisms 4 is deduced from the above. Each bag feeding mechanism 3 has one or more bag feeding platforms 31, which can be selected by those skilled in the art as needed. In Embodiment 1, the bag feeding mechanism 3 is located at the end of the translation track 1, and includes a bag feeding platform 31 located on the front or rear side of the end of the translation track 1, or includes two bag feeding platforms 31 symmetrically arranged about the front and rear of the end of the translation track 1. Correspondingly, the bag feeding transmission unit 34 is used to drive a bag feeding trolley 33 to reciprocate between the bag feeding platform 31 and the first transfer unit 61.

[0098] Figure 2 and Figure 3The diagram shows a second embodiment of the sorting system of this utility model. The difference between this second embodiment and the first embodiment is that multiple sorting mechanisms 4 are arranged on the left and right sides of the feeding mechanism 3 along the extension direction of the translation track 1. The feeding mechanism 3 is located at a non-end position of the translation track 1, preferably in the middle of the translation track 1. The feeding mechanism 3 includes four feeding platforms 31, symmetrically arranged about the translation track 1 along its horizontal width. Correspondingly, the feeding transmission unit 34 drives two feeding trolleys 33 to reciprocate between the feeding platforms 31 and two adjacent transfer units 6. The number of sorting mechanisms 4 located on both sides of the feeding mechanism 3 can be the same or different.

[0099] Figure 4 and Figure 5 The diagram shows a third embodiment of the sorting system of this utility model. In this embodiment, the translation track is zigzag-shaped and includes multiple connecting segments that are connected end to end. These connecting segments are arranged in an arc shape, with an angle of 90° between adjacent connecting segments. A package feeding mechanism 3 is located at one end of the translation track, and a sorting mechanism 4 is correspondingly provided at each connecting segment. The transfer unit in each sorting mechanism 4 is located at one end of the connecting segment, facilitating docking with the package feeding mechanism 3 or the adjacent sorting mechanism 4.

[0100] Figure 6 The diagram shows Embodiment 4 of the sorting system of this utility model. In Embodiment 4, the translation track is also of a broken-line shape, including multiple connecting segments connected end-to-end, with an angle of 90° between adjacent connecting segments. The difference between Embodiment 4 and Embodiment 3 is that the multiple connecting segments are arranged in a stepped pattern.

[0101] In addition to Embodiments 3 and 4 above, multiple connecting segments can also be arranged in an L-shape.

[0102] Figure 6 The figure shown is a fifth embodiment of the sorting system of this utility model. In this fifth embodiment, the translation track is T-shaped and includes a first branch extending in the front-back direction and two second branches extending in the left-right direction. The package feeding mechanism 3 is located at one end of the first branch or the second branch.

[0103] Figure 7 The figure shown is a sixth embodiment of the sorting system of this utility model. In this sixth embodiment, the translation track is maze-shaped, including a first branch extending in the front-back direction and multiple second branches extending in different horizontal directions. The second branches are all connected to the first branch. The package feeding mechanism 3 is located at one end of the first branch.

[0104] Furthermore, such as Figure 1As shown, the package feeding drive unit 34 includes a package feeding drive component connected to the package feeding carriage 33; the sorting drive unit 9 includes a sorting drive component connected to the sorting carriage 5. The package feeding drive component and the sorting drive component can be ball screws driven by a motor, with their sliders connected to the package feeding carriage 33 / sorting carriage 5; or they can be cables, ropes, belts, or chains disposed between a pair of driving wheels and driven wheels.

[0105] In Embodiments 1, 3 to 5, the package feeding drive extends from the location of the package feeding platform 31 to the adjacent transfer unit 6; in Embodiment 2, the package feeding drive extends from the transfer unit 6 adjacent to its left to the transfer unit 6 adjacent to its right. In the adjacent package feeding mechanism 3 and sorting mechanism 4, the package feeding drive and the sorting drive have an overlapping section at the transfer unit 6, so the package feeding trolley 33 can reciprocate along the translation track 1 between the package feeding platform 31 and the transfer unit 6 of the adjacent sorting mechanism 4.

[0106] The sorting drive unit located at the non-end position of the translation track 1 extends from the transfer unit 6 of its respective sorting mechanism 4 to the transfer unit 6 of the adjacent sorting mechanism 4, which is relatively far from the feeding mechanism 3. That is, in two adjacent sorting mechanisms 4, the two sorting drive units have overlapping sections at the transfer unit 6, which is far from the feeding mechanism 3. Therefore, the sorting trolley 5 located at the non-end position of the translation track 1 can reciprocate along the translation track 1 between the transfer unit 6 and the receiving unit 7 of the same sorting mechanism 4 to complete one item delivery, and can also reciprocate along the translation track 1 between the transfer units 6 of two adjacent sorting mechanisms 4 to achieve relay transmission of items. The sorting drive unit located at the end position of the translation track 1 extends from the transfer unit 6 of its respective sorting mechanism 4 to the receiving unit 7 of the same sorting mechanism 4. Therefore, the sorting trolley 5 located at the end position of the translation track 1 can reciprocate between the transfer unit 6 and the receiving unit 7 of the same sorting mechanism 4.

[0107] As can be seen from Embodiments 1 to 6, the sorting system provided by this utility model can achieve unlimited expansion on the horizontal plane by increasing the number of sorting mechanisms 4 set along the translation track 1, and complete single-layer package feeding and single-layer sorting.

[0108] Furthermore, to improve the sorting efficiency of the sorting system and achieve the functions of single-layer feeding and multi-layer sorting, such as... Figure 1-4As shown, the sorting system of this utility model also includes a fixedly installed frame 2, with N sets of translation tracks 1 spaced apart along the height direction of the frame 2. Each set of translation tracks 1 includes one translation track 1 or two parallel translation tracks 1. Compared to moving along one translation track 1, the movement of the sorting trolley 5 along two translation tracks 1 simultaneously is undoubtedly more stable. The N sets of translation tracks 1 divide the frame 2 into N layers. At the same time, the packaging mechanism 3 includes N packaging components spaced apart along the height direction of the frame 2, and the sorting mechanism 4 includes N sorting components spaced apart along the height direction of the frame 2, where N is an integer greater than or equal to 2. There is a one-to-one correspondence between the N packaging components, the N sorting components, and the N sets of translation tracks 1. That is, the packaging mechanism 3 has one packaging component in each layer, and the sorting mechanism 4 has one sorting component in each layer, ensuring that items can be directly or relayed along a set of translation tracks 1 in each layer.

[0109] The feeding mechanism 3 also includes a feeding lifting unit 32 disposed between the feeding platform 31 and the frame 2. The feeding lifting unit 32 includes a lifting feeding trolley, which is used to transport multiple items provided by the feeding platform 31 to feeding trolleys 33 of different feeding components. Each sorting mechanism 4 also includes a sorting lifting unit 8. The sorting lifting unit 8 and the transfer unit 6 are disposed on different sides of the translation track 1 and the frame 2 along the horizontal width direction of the translation track 1. That is, the corresponding positions of the sorting lifting unit 8 and the transfer unit 6 on the translation track 1 are the same. The conveyor belt of the sorting trolley 5 or the feeding trolley 33 can be moved in different directions to dock with the sorting lifting unit 8 or the transfer unit 6. The sorting lifting unit 8 includes a lifting sorting trolley and a receiving part 800 disposed on the outside of the sorting lifting trolley (here, "outside" refers to the side away from the sorting trolley 5). The sorting lifting trolley is used to transport items between sorting trolleys 5 at different heights; the receiving section 800 is used to receive items that cannot be delivered due to malfunction of the sorting components. Specifically, both the package feeding lifting trolley and the sorting lifting trolley have conveyor belts that can move in the front-to-back direction. The receiving section 800 is fixedly installed at the bottom of the sorting lifting unit 8, and includes one or more receiving baskets arranged side by side in the left-to-right direction.

[0110] The functions of the package feeding lifting unit 32 and the sorting lifting unit 8 will be explained below with reference to the embodiments:

[0111] In Example 1, N=5, that is, 5 sets of translation tracks 1 are arranged at intervals along the height direction of the frame 2, dividing the frame 2 into 5 layers.

[0112] When the sorting system is working normally, the feeding lifting trolley can transport the items provided by the feeding table 31 to the feeding trolley 33 on any layer. Then the items are transferred between the transfer unit 6 and the sorting trolley 5 on the same layer as the feeding trolley 33, and finally delivered to the receiving unit 7 on the same layer.

[0113] When the sorting component on the third layer of the first sorting mechanism 41 malfunctions, but the items need to be transported to the second receiving unit 72 on the third layer of the second sorting mechanism 42, the sorting system operates as follows: The feeding lifting trolley transports the items provided by the feeding table 31 to the feeding trolley 33 on the third layer. The feeding trolley 33 moves to the first sorting lifting unit 81 of the first sorting mechanism 41 and transports the items to the first sorting lifting trolley in the first sorting lifting unit 81. The first sorting lifting trolley transports the items to the first sorting trolley 51 on the second layer. Then, the first sorting trolley 51 moves to the second sorting lifting unit 82 of the second sorting mechanism 42. The second sorting lifting trolley in the second sorting lifting unit 82 transports the items to the second sorting trolley 52 on the third layer. The second sorting trolley 52 delivers the items to the second receiving unit 72 on the third layer.

[0114] When the sorting component in the third layer of the first sorting mechanism 41 malfunctions, but it is necessary to transport the items to the first receiving unit 71 in the third layer, the sorting system works as follows: the supply lifting trolley transports the items provided by the supply table 31 to the supply trolley 33 in the third layer, the supply trolley 33 moves to the first sorting lifting unit 81 and transports the items to the first sorting lifting trolley, the first sorting lifting trolley descends to the vicinity of the receiving section 800 and transports the items to the receiving section 800.

[0115] As can be seen from the above, compared to a sorting system with a single-layer structure that can only expand infinitely in the horizontal plane, a sorting system with a multi-layer structure can expand vertically to increase the sorting capacity, and also allows the feeding carts 33 and sorting carts 5 on different layers to work simultaneously, realizing the function of single-layer feeding and multi-layer sorting, which greatly improves the sorting efficiency of items. At the same time, by setting a sorting lifting unit 8 in each sorting mechanism 4, this utility model can both detour around the faulty layer during relay transmission and accommodate items that cannot be delivered, thereby avoiding the failure of a single sorting component from affecting the normal operation of the entire sorting system, reducing the maintenance frequency of the sorting system, and further ensuring the efficient operation of the sorting system.

[0116] Specifically, such as Figure 1 and Figure 9As shown, the bag feeding platform 31 includes a bag feeding frame 310 with a bag feeding area 3101, and multiple sets of conveying assemblies assembled in the bag feeding area 3101 along the front-to-back direction. Each set of conveying assemblies includes a conveying drive source, a pair of support rollers, and a conveyor belt 311 connected to the outer periphery of the pair of support rollers. The support rollers are rotatably supported in the bag feeding frame 310 and are connected to the conveying drive source. A triangular area 312 is formed between adjacent sets of conveying assemblies. After being conveyed by the conveyor belts 311 of the multiple sets of conveying assemblies, the items are conveyed to the bag feeding lifting trolley or the bag feeding trolley 33.

[0117] Preferably, the support roller is a small-diameter roller with a diameter of no more than 40 mm. Because the support roller is a small-diameter roller with a diameter of no more than 40 mm, it can significantly reduce the size of the triangular-like area 312 formed between two adjacent sets of conveying components, making the connection between the two sets of conveying components smoother. This effectively prevents small items from getting stuck in the triangular-like area 312, ensuring that items can pass smoothly through multiple sets of conveying components and significantly reducing the probability of items falling off.

[0118] like Figure 10 As shown, the sorting trolley 5 includes a support frame with one or more conveyor sections mounted on it. Each conveyor section includes multiple rollers 501 rotatably mounted on the support frame and a conveyor belt 502 connecting the multiple rollers 501. One or more rollers 501 in each conveyor section are electric rollers or connected to a rotary drive source. When the rollers 501 rotate, the conveyor belt 502 moves forward or backward. When multiple conveyor sections are provided on the support frame, they are spaced apart on the support frame in a left-right direction. Sorting personnel can place items of different sizes or types on different conveyor belts 502 of the same sorting trolley 5 as needed, increasing the number of items transported by each sorting trolley 5 in a single trip. When the sorting trolley 5 arrives at the designated receiving unit 7, different conveyor sections are controlled to complete the delivery, thereby improving sorting efficiency.

[0119] The support also includes two baffles 506, which extend along the conveying direction (i.e., the front-to-back direction) of the conveyor belt 502. The two baffles 506 are arranged on the left and right sides of the conveyor belt 502 along the extension direction of the translation track 1, and form a first opening 5041 and a second opening 5042 with the front and rear ends of the conveyor belt 502, respectively. The sorting trolley 5 also includes a blocking part 503 for preventing objects placed on the conveyor belt from passing through the first opening 5041 and / or the second opening 5042.

[0120] In one embodiment of the blocking part 503, the blocking part 503 includes two blocking units, which are respectively disposed at the first opening 5041 and the second opening 5042. Each blocking unit includes a gate 5031 and a drive source 5032, which drives the gate 5031 to move closer to or away from the first opening 5041 or the second opening 5042. The bracket is also provided with a plurality of translation wheels 505 that are slidably disposed in the grooves of the translation track 1.

[0121] When the sorting trolley 5 receives / delivers materials, the drive source 5032 drives the gate 5031 away from the first opening 5041 / second opening 5042, allowing the materials to pass smoothly through the first opening 5041 / second opening 5042 and enter or leave the conveyor belt 502. When the sorting trolley 5 transports materials, the drive source 5032 drives the gate 5031 to move to the bottom of the first opening 5041 / second opening 5042, blocking the materials placed on the conveyor belt 502 and preventing them from falling down through the first opening 5041 / second opening 5042.

[0122] The drive source 5032 can be a linear displacement drive source or a rotary drive source. When the drive source 5032 is a linear displacement drive source, it drives the gate 5031 to move up and down, allowing the gate 5031 to move linearly back and forth within the range from the bottom of the first opening 5041 / second opening 5042 to the top of the first opening 5041 / second opening 5042. Specifically, the linear displacement drive source can be a lead screw motor, an electromagnet, etc. When the drive source 5032 is a rotary drive source, it drives the gate 5031 to rotate, allowing the gate 5031 to rotate within the range from the bottom of the first opening 5041 / second opening 5042 to the left / right side of the first opening 5041 / second opening 5042. Specifically, the rotary drive source can be a stepper motor or a servo motor.

[0123] In the second embodiment of the blocking part 503, the blocking part 503 is disposed on the conveyor belt 502, and includes a plurality of stops spaced apart along the extension direction of the conveyor belt 502. The stops extend along the width direction of the conveyor belt 502, and their specific shape is not limited, and can be strip-shaped, plate-shaped, block-shaped, column-shaped, or irregularly shaped, etc. When the sorting trolley 5 receives / delivers materials, the roller 501 drives the conveyor belt 502 to move forward, so that one stop is located at the bottom of the conveyor belt 502 and the other stop is located at the top of the conveyor belt 502, and the materials can smoothly pass through the first opening 5041 / second opening 5042 to enter or leave the conveyor belt 502; when the sorting trolley 5 transports materials, the roller 501 drives the conveyor belt 502 to move backward, at which time both stops are located at the top of the conveyor belt 502, and the materials are located between the two stops. The forward and backward movement of the materials is blocked by the stops, and they cannot fall down through the first opening 5041 / second opening 5042.

[0124] like Figure 1 As shown, the transfer unit 6 includes one or more transfer trolleys, each with a conveyor belt that can move in the forward and backward direction. When each transfer unit 6 has multiple transfer trolleys, the multiple transfer trolleys are spaced apart along the extension direction of the translation track 1.

[0125] Furthermore, the structures of the aforementioned bag supply trolley 33, transfer trolley, bag supply lifting trolley, and sorting lifting trolley are all the same as the structure of the sorting trolley 5.

[0126] Furthermore, the structure of the package feeding lifting unit 32 and the sorting lifting unit 8 is identical, both including one or more lifting components. Each lifting component includes a fixed frame, which is rectangular in shape, with a lifting drive source at its top. The lifting drive source drives the lifting synchronous shaft to rotate. Two lifting drive wheels are mounted on the lifting synchronous shaft, and two lifting driven wheels are mounted at the bottom of the fixed frame. A lifting transmission component is located between the lifting drive wheels and the lifting driven wheels on the same side. The two lifting transmission components are connected to the lifting frame, and a package feeding lifting trolley / sorting lifting trolley is fixedly connected within the lifting frame. When the lifting drive source drives the lifting synchronous shaft to rotate, it can simultaneously drive the lifting frame and the package feeding lifting trolley / sorting lifting trolley located between the two lifting transmission components to perform lifting movements. Specifically, the lifting drive source can be a stepper motor or a servo motor.

[0127] 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.
