Description

Technical Field

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

[0002] Automatic sorting and distribution equipment is mainly used to classify goods and packages according to prescribed rules, such as sorting goods according to orders. It can effectively improve the efficiency and accuracy of sorting and distribution.

[0003] To improve the efficiency and flow rate of sorting units, existing automated sorting and distribution equipment is designed with a three-dimensional orientation. Existing technology provides a sorting device comprising a sorting unit and two sorting tracks spaced vertically apart. The sorting unit includes a lifting column, a sorting platform vertically mounted on the lifting column, a drive wheel mechanism mounted at one end of the lifting column, and a follower wheel assembly mounted at the other end of the lifting column. The drive wheel mechanism is self-driven and travels on one sorting track, while the follower wheel assembly travels on the other sorting track.

[0004] Existing sorting equipment utilizes a drive wheel mechanism and a follower wheel assembly to enable the sorting mechanism to travel on a sorting track. However, because the drive wheel mechanism is located at one end of the lifting column, the sorting mechanism suffers from an imbalance in vertical force, which can easily cause the two ends of the sorting mechanism to skew during operation. Consequently, the operational stability and reliability of the sorting mechanism cannot be effectively guaranteed. Utility Model Content

[0061] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0062] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0063] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0064] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0065] This embodiment provides a sorting device that can automatically sort and distribute items, improve sorting efficiency and flexibility, and enhance sorting reliability.

[0066] like Figure 1 and Figure 2 As shown, the sorting equipment provided in this embodiment includes a sorting track 200, a sorting device 100, a shelf, and a control system. The shelf is located on one side of the sorting track 200 and has multiple sorting containers. The sorting device 100 runs along the sorting track 200 to unload the items it carries into the target sorting containers. The control system is communicatively connected to the sorting device 100 to control the operation of the sorting device 100.

[0067] Specifically, the sorting device 100 includes a sorting mechanism 1 and a sorting drive mechanism 2. The sorting mechanism 1 includes a vertically extending mounting column 11, a platform 12 that can be raised and lowered along the mounting column 11, and two walking guide components 14 spaced apart along the height direction of the mounting column 11. The sorting drive mechanism 2 is installed on the side of the mounting column 11 away from the platform 12 and spaced apart between the two walking guide components 14. The sorting drive mechanism 2 can rotate relative to the mounting column 11 around a vertical axis.

[0068] The sorting track 200 includes two guide tracks 201 that are arranged vertically opposite each other and spaced apart, and a travel track 202 that is spaced apart between the two guide tracks 201. Two travel guide components 14 are respectively in rolling cooperation with the two guide tracks 201, and the sorting drive mechanism 2 travels on the travel track 202.

[0069] The sorting device 100 and sorting equipment provided in this embodiment, by setting two walking guide components 14 that cooperate with two guide rails 201, allow both ends of the sorting device 100 to be stably supported on the guide rails 201 through the two walking guide components 14, preventing the sorting device 100 from falling off the sorting rails 200, thus improving the operational stability and reliability of the sorting mechanism 1; by setting the sorting drive mechanism 2 at intervals between the two walking guide components 14, the setting position of the sorting drive mechanism 2 is approximately located in the middle of the sorting mechanism 1 along the height direction, thereby better ensuring the overall force balance of the entire sorting mechanism 1, effectively reducing the swaying of the sorting device 100 in the vertical plane during operation and the sorting mechanism The sorting mechanism 100 addresses issues such as tilting, improves drive stability, and effectively avoids interference between the sorting drive mechanism 2 and the walking guide component 14, thus enhancing the structural layout rationality of the sorting device 100. Furthermore, since the sorting drive mechanism 2 can rotate relative to the mounting column 11 around the vertical axis, it is more conducive to the operation of the sorting device 100 on the sorting track 200 with curved track sections, improving the smoothness and reliability of the sorting device 100's turning and enhancing its versatility for various tracks. Moreover, separating the sorting drive mechanism 2 from the walking guide component 14 facilitates the modular design of the sorting mechanism 1, thereby enabling the linkage connection between multiple sorting mechanisms 1 and expanding the application scenarios of the sorting device 100.

[0070] In this embodiment, the sorting mechanism 100 further includes a lifting drive assembly 13, which drives the platform 12 to move up and down along the mounting column 11. It is worth noting that the lifting drive assembly 13, the shelf, the sorting track 200, and the control system can be configured with reference to existing technologies. This is not the focus of the improvement of this utility model, and the utility model does not limit or elaborate on this aspect.

[0071] In this embodiment, a plurality of sorting devices 100 are provided on the sorting track 200. Each sorting device 100 includes at least one sorting mechanism 1 and a sorting drive mechanism 2 that drives the sorting mechanism 1 to run along the sorting track 200, thereby improving the sorting capacity of the sorting equipment.

[0072] Furthermore, each sorting drive mechanism 2 can be individually controlled by the control system, allowing the control system to regulate the operating speed and acceleration of each sorting device 100. This enables the sorting device 100 to better match its operating speed at various points on the sorting track 200 with its position on the sorting track 200. For example, it can operate at a relatively low speed when loading and unloading, and at a relatively high speed at other locations, thereby improving sorting flexibility and efficiency, as well as sorting stability and reliability.

[0073] In this embodiment, at least a portion of the sorting device 100 includes at least two sorting mechanisms 1 arranged side-by-side and linked together, and at least one sorting mechanism 1 is provided with a sorting drive mechanism 2. This satisfies sorting requirements while reducing the number of sorting drive mechanisms 2, thus lowering costs. Furthermore, this cooperative arrangement of the sorting device 100 and the sorting track 200 effectively reduces the number and arrangement of the sorting devices 100 relative to the sorting track 200, allowing for flexible adjustments to the number of sorting devices 100 based on the number of sorting slots, thereby improving the flexibility and reliability of the sorting equipment.

[0074] For ease of description, the sorting mechanism 1 equipped with the sorting drive mechanism 2 is referred to as the active sorting mechanism 1a, and the sorting mechanism 1 in the same sorting device 100 that is not equipped with the sorting drive mechanism 2 is referred to as the follow-up sorting mechanism 1b.

[0075] In this embodiment, among the multiple sorting mechanisms 1 of the same sorting device 100, the sorting mechanism 1 located at the foremost side in the preset travel direction is the active sorting mechanism 1a, and the rest are follower sorting mechanisms 1b. This allows the foremost active sorting mechanism 1a to pull the follower sorting mechanisms 1b behind it, thus more effectively improving the operational stability and reliability of the entire sorting device 100. In another embodiment, the sorting mechanism 1 located at the rearmost side in the preset travel direction may be the active sorting mechanism 1a, so that the active sorting mechanism 1a drives the remaining follower sorting mechanisms 1b. In yet another embodiment, the middle sorting mechanism 1 may be the active sorting mechanism 1a, thereby achieving the driving of the remaining follower sorting mechanisms 1b through a push-pull combination.

[0076] In this embodiment, the sorting track 200 is a racetrack-shaped track, with its length direction along a first direction and its width direction along a second direction. That is, the sorting track 200 includes two straight track segments arranged opposite each other and spaced apart in the second direction, and two arc-shaped track segments connecting the two ends of the two straight track segments. The straight track segments extend along the first direction. The sorting device 100 reciprocates along the sorting track 200. In other embodiments, the sorting track 200 may also be a circular track or a non-circular track of other shapes.

[0077] like Figures 3 to 5 As shown, the walking guide assembly 14 includes a mounting base 141 and a guide wheel assembly. The mounting base 141 is mounted on the side of the mounting column 11 facing the sorting track 200. The guide wheel assembly includes two first guide wheels 143 that are opposite to each other and spaced apart in the width direction of the guide track 201. The first guide wheels 143 can rotate relative to the mounting base 141, and the axis of rotation is arranged in the vertical direction. The first guide wheel 143 away from the mounting column 11 rolls with the inner side of the guide track 201, and the other first guide wheel 143 rolls with the outer side of the guide track 201, so that the guide track 201 is clamped between the two first guide wheels 143 to prevent the walking guide assembly 14 from detaching from the guide track 201.

[0078] The guide wheel assembly also includes a second guide wheel 144, which rolls with the side of the guide rail 201 facing the direction of the travel rail 202. That is, in the upper travel guide assembly 14, the second guide wheel 144 rolls with the lower side of the guide rail 201, and in the lower travel guide assembly 14, the second guide wheel 144 rolls with the upper side of the guide rail 201. This better achieves the vertical limitation of the sorting mechanism 1 relative to the sorting rail 200, reduces the probability of the travel guide assembly 14 disengaging from the corresponding guide rail 201 in the vertical direction, and further improves the operational stability and reliability of the sorting device 100.

[0079] The guide wheel assembly is rotatably mounted on the mounting base 141 via a mounting shaft 146, which is vertically positioned. This rotation of the guide wheel assembly relative to the mounting base 141 improves the smoothness of the travel guide assembly 14 along the arc-shaped track section, preventing obstruction during operation. Specifically, the guide wheel assembly also includes a wheel seat 142, which is rotatably mounted on the mounting base 141 via the mounting shaft 146, and the guide wheels are rotatably mounted on the wheel seat 142. Two guide wheel assemblies are spaced apart along the extension direction of the guide track 201 to improve guiding stability and reliability, thereby enhancing the operational stability and reliability of the sorting device 100.

[0080] The first guide wheel 143 and the second guide wheel 144 are both rotatably mounted on the wheel seat 142. Specifically, the wheel seat 142 includes a base plate and two side brackets connected to opposite sides of the base plate. The base plate and the two side brackets together form a mounting groove. The second guide wheel 144 is located in the mounting groove and its axle is rotatably mounted on the two side brackets. The two first guide wheels 143 are rotatably mounted on the two side brackets. A mounting shaft 146 is connected to the side of the base plate away from the second guide wheel 144 and is rotatably mounted on the mounting base 141. Further, the side bracket includes a first plate perpendicularly connected to the base plate and a second plate connected to the end of the first plate away from the base plate. The second plate extends in a direction away from the second guide wheel 144, and the first guide wheel 143 is rotatably mounted on the second plate.

[0081] The walking guide assembly 14 also includes a seat baffle 145, which is connected to the side of the two second plates opposite to the first plate. The seat baffle 145 has a clearance opening opposite the position of the second guide wheel 144. The side of the second guide wheel 144 away from the bottom plate is exposed through the clearance opening and contacts the guide rail 201. The axle of the first guide wheel 143 passes through the seat baffle 145 and is connected to the second plate.

[0082] like Figure 6 and Figure 7 As shown, in order to enable the active sorting mechanism 1a to drive the follow-up sorting mechanism 1b, among the multiple sorting mechanisms 1 located in the same sorting device 100, two adjacent sorting mechanisms 1 are connected by a linkage structure, and the linkage structure allows the two adjacent sorting mechanisms 1 to deflect horizontally relative to each other. This makes the connection between the two adjacent sorting mechanisms 1 non-rigid, and the two adjacent sorting mechanisms 1 can be offset relative to each other, so as to better meet the movement of the sorting device 100 on the arc track section.

[0083] In this embodiment, the linkage structure connecting the active sorting mechanism 1a and the adjacent follower sorting mechanism 1b is a linkage component 5. The linkage component 5 only allows the mounting columns 11 of the two active sorting mechanisms 1a and the mounting columns 11 of the follower sorting mechanism 1b to deflect horizontally relative to each other. This allows the follower sorting mechanism 1b adjacent to the active sorting mechanism 1a to rotate relative to the active sorting mechanism 1a around its vertical axis, while simultaneously maintaining the vertical operating state of the active sorting mechanism 1a. This avoids tilting caused by the pulling of the follower sorting mechanism 1b, and also helps maintain the vertical state of the follower sorting mechanism 1b during its operation, reducing the probability of overall tilting of the sorting device 100 and improving the operational reliability and stability of the sorting device 100.

[0084] In other embodiments, the linkage structure can only deflect horizontally relative to the active sorting mechanism 1a, while the linkage structure can deflect horizontally and vertically relative to the corresponding follower sorting mechanism 1b, so that while maintaining the vertical operation state of the active sorting mechanism 1a, the adjacent follower sorting mechanism 1b floats vertically relative to the active sorting mechanism 1a, so as to meet the operation when the travel track 202 is uneven.

[0085] In this embodiment, the linkage 5 and the two corresponding sorting mechanisms 1 are rotatably connected relative to each other via a vertical rotating shaft structure, so that the linkage 5 can only rotate horizontally relative to the mounting column 11 of the corresponding sorting mechanism 1. In other embodiments, the linkage 5 is connected to the mounting column 11 of the active sorting mechanism 1a via a vertical rotating shaft structure, and the linkage 5 is connected to the mounting column 11 of the corresponding follow-up sorting mechanism 1b via a ball joint structure.

[0086] The linkage structure connecting two adjacent follow-up sorting mechanisms 1b is the connecting component 4. The two adjacent follow-up sorting mechanisms 1b can tilt vertically and horizontally relative to each other through the connecting structure. By allowing the two adjacent follow-up sorting mechanisms 1b to tilt horizontally, it is easier to adapt to the synchronous operation of two sorting mechanisms 1b along an arc-shaped track section, ensuring the operational reliability of the sorting track 200. The vertical tilting of the two adjacent follow-up sorting mechanisms 1b allows them to move up and down with the surface of the guide track 201 when the guide track 201 is uneven, avoiding rigid tension between the two follow-up sorting mechanisms 1b and improving the operational reliability and stability of the sorting device 100. In other embodiments, the connecting structure connecting two adjacent follow-up sorting mechanisms 1b may allow only one end to tilt vertically relative to the corresponding sorting mechanism 1.

[0087] To improve the ease of setting up the linkage structure, the linkage structure can rotate relative to the sorting mechanism 1 connected to it around an axis extending in the vertical direction, and the axis of rotation is coaxial with the axis of a mounting shaft 146. Thus, the axis of rotation at both ends of the linkage structure is the axis of rotation of the guide wheel group of the two sorting mechanisms 1, so that the deflection of the linkage structure relative to the sorting mechanism 1 is consistent with the deflection of the guide wheel group relative to the guide rail 201. Thus, when the sorting device 100 is running on the arc track section, the sorting mechanism 1 on the front side can pull the sorting mechanism 1 on the rear side to turn, ensuring the synchronous operation of the two adjacent sorting mechanisms 1 on the arc track section, and avoiding the problem of subsequent sorting mechanism 1 getting stuck when the sorting mechanism 1 turns.

[0088] It is worth noting that the terms "front" and "rear" in the preceding and following texts refer to the preset travel direction of the sorting device 100. The side in front of the preset travel direction is "front", and the side behind the preset travel direction is "rear".

[0089] To improve the ease of setting up the linkage structure, in this embodiment, both ends of the linkage structure are connected to the mounting shafts 146 of the walking guide components 14 of the two sorting mechanisms 1, respectively. That is, the axis of rotation of the linkage structure relative to the mounting columns 11 of the two sorting mechanisms 1 is the axis of the mounting shaft 146. This allows the rotation of the wheel seat 142 relative to the mounting columns 11 to drive the linkage structure to rotate, simplifying the connection structure of the linkage structure and making it easier to ensure the synchronous operation of the two adjacent sorting mechanisms 1 on the arc-shaped track section. In other words, the vertical rotating shaft structure is the mounting shaft 146 of the corresponding sorting mechanism 1. In this embodiment, the linkage component 5 is a long strip plate structure, which is horizontally arranged and vertically connected to the mounting shaft 146 to simplify the structure of the linkage component 5 and reduce its cost.

[0090] In the same travel guide assembly 14, the mounting shaft 146 located in front of the preset travel direction is called the front mounting shaft 146a, and the other mounting shaft 146 is called the rear mounting shaft 146b. The front end of the linkage structure is connected to the rear mounting shaft 146b of the front sorting mechanism 1, and the rear end of the linkage structure is connected to the front mounting shaft 146a of the rear sorting mechanism 1. This configuration avoids interference between the linkage structure and the walking guide component 14. While simplifying the connection between the connecting component 4 and the sorting mechanism 1, the turning of the front sorting mechanism 1 will drive the rear mounting shaft 146b to rotate, thereby causing the sorting mechanism 1 to deflect relative to the linkage structure. At the same time, it pulls the rear sorting mechanism 1 to turn. This avoids the linkage structure affecting the turning of the sorting mechanism 1, while achieving synchronous operation of the two adjacent sorting mechanisms 1 when turning, improving the smoothness of the sorting device 100's operation. Furthermore, since the deflection state of the guide wheel set on the front sorting mechanism 1 relative to the sorting track 200 is closer to the deflection state of the guide wheel set on the adjacent rear side relative to the sorting track 200, it can reduce the horizontal deflection amplitude of the linkage structure when turning while ensuring that the front sorting mechanism 1 pulls the rear sorting mechanism 1, thus better ensuring the smoothness of the sorting device 100's operation.

[0091] To improve the ease of connection between the mounting shaft 146 and the linkage structure, the mounting shaft 146 passes through the mounting plate 21, and the linkage structure and wheel seat 142 are located on opposite sides of the mounting plate 21 to avoid interference between the linkage structure and the guide wheel assembly. In this embodiment, the linkage component 5 is a long strip plate-shaped structure, which is horizontally arranged and vertically connected to the linkage shaft to simplify the structure of the linkage component 5 and reduce its cost.

[0092] like Figures 7 to 9 As shown, at least one end of the connecting component 4 is connected to the follow-up sorting mechanism 1b via a ball joint, thereby enabling the connecting component 4 to rotate relative to the mounting column 11 of the follow-up sorting mechanism 1b within a certain cone angle range. This allows it to better adapt to the unevenness of the sorting track 200 and ensure the stability and smoothness of the entire sorting device 100.

[0093] A mounting shaft 146 is rotatably mounted on the mounting column 11 of the follow-up sorting mechanism 1b. The mounting shaft 146 is vertically arranged, and both ends of the connecting component 4 are provided with hinge joints 42, which are connected to the mounting shaft 146 to form a ball joint structure. That is, in this embodiment, both ends of the connecting component 4 are connected to the follow-up sorting mechanism 1b through a ball joint structure, so as to better ensure the linkage between the two follow-up sorting mechanisms 1b and better adapt to sorting tracks 200 with different flatness.

[0094] Specifically, the connecting assembly 4 includes a connecting seat 41 and a hinge joint 42 connected to the front and rear ends of the connecting seat 41. The hinge joint 42 is connected to the mounting shaft 146. The hinge joint 42 preferably, but not limited to, adopts a hinge structure that can achieve multi-directional rotation, such as a ball joint or a spherical bearing.

[0095] In this embodiment, the hinge joint 42 includes a hinge portion 421 and a connecting rod portion 422. The hinge portion 421 is hinged to the mounting shaft 146, and the connecting rod portion 422 is detachably connected to the connecting seat 41. Specifically, the connecting seat 41 is provided with a locking bolt 43, the threaded section of which extends out of the connecting seat 41. The end of the connecting rod portion 422 away from the hinge portion 421 is provided with a connecting threaded hole, and the threaded section is screwed into the connecting threaded hole. A positioning cut surface 4221 is cut on the connecting rod portion 422, and the positioning cut surface 4221 is horizontally arranged to position the installation position of the hinge joint 42.

[0096] The connecting base 41 includes a detachable connecting plate 411 and a fixing block 412. The connecting plate 411 has mounting grooves 4111 on opposite sides. The fixing block 412 has a connecting through hole 4121. The fixing block 412 and the mounting groove 4111 are arranged in a one-to-one correspondence. The connecting through hole 4121 communicates with the mounting groove 4111. The locking member passes through the connecting through hole 4121 and the screw head is located between the bottom of the mounting groove 4111 and the fixing block 412 to achieve the internal setting of the locking bolt 43.

[0097] The fixing block 412 has mounting slots 4122 on both sides of the connecting through hole 4121, so that the fixing block 412 forms an "I" shaped structure. The connecting plate 27 has connecting arms 4112 on both sides of the mounting groove 4111. The two connecting arms 4112 are respectively inserted into the two mounting slots 4122, and the connecting arms 4112 and the fixing block 412 are connected by fasteners 44 passing through them, so as to facilitate the installation and positioning of the fixing block 412 and the connecting plate 411, while improving the overall structural compactness of the connecting assembly 4.

[0098] like Figure 2 and Figure 6As shown, in this embodiment, a limiting buffer 8 protrudes forward from the front side of the active sorting mechanism 1a along the preset travel direction. The limiting buffer 8 is used to prevent the active sorting mechanism 1a from rigidly colliding with the sorting device 100 on the front side, avoiding damage to the sorting mechanism 1a due to rigid collision, and improving the operational safety and reliability of the sorting device 100. The limiting buffer 8 can adopt the structure of the prior art, and this embodiment does not limit it. The limiting buffer 8 is connected to the mounting base 141 and the seat baffle 145 of the travel guide assembly 14 to improve the setting stability and reliability of the limiting buffer 8. The limiting buffer 8 is preferably set on the lower side of the sorting mechanism 1 to facilitate disassembly, maintenance and replacement.

[0099] like Figure 10 and Figure 11 As shown, in this embodiment, the platform 12 is located on the side of the mounting column 11 away from the sorting track 200, and the walking guide assembly 14 and the walking drive mechanism are both located on the side of the mounting column 11 away from the platform 12, so as to avoid interference between the structures and improve the convenience of cooperation between the walking drive mechanism and the travel track 202.

[0100] To improve the reliability of the sorting drive mechanism 2 along the travel track 202, in this embodiment, a connecting column 31 is connected to the sorting mechanism 1 on which the sorting drive mechanism 2 is provided. The connecting column 31 can rotate relative to the sorting mechanism 1 about a vertical axis, and the sorting drive mechanism 2 is mounted on the connecting column 31. This arrangement allows the sorting drive mechanism 2 to rotate synchronously along the sorting track 200 when the active sorting mechanism 1a turns, and the sorting drive mechanism 2 can deflect relative to the active sorting mechanism 1a about a vertical axis, so as to better ensure the consistency of the turning of the two, improve the smoothness of turning, and avoid running jamming when turning.

[0101] The sorting drive mechanism 2 can float vertically relative to the sorting mechanism 1, allowing them to move relative to each other in the vertical direction. This enables the sorting drive mechanism 2 to adapt to the surface height of the travel track 202 when the travel track 202 is uneven, preventing operational jamming caused by unevenness. Furthermore, when the distance between the guide track 201 and the travel track 201 differs from the design, the vertical relative position adjustment of the sorting drive mechanism 2 and the sorting mechanism 1 better ensures reliable installation and stable operation of the sorting device 100 on the sorting track 200. This provides a margin of error for the stable operation of the sorting device 100, reduces the processing accuracy requirements of the travel track 202, and improves the operational stability and reliability of the sorting device 100.

[0102] The sorting device 100 also includes a floating component 3, which includes a connecting column 31. The sorting drive mechanism 2 is mounted on the connecting column 31, which can float up and down. Both ends of the connecting column 31 are detachably connected to the mounting column 11. Therefore, when assembling the sorting device 100, the sorting mechanism 1 and the sorting drive mechanism 2 can be assembled separately. After assembling the sorting drive mechanism 2 with the connecting column 31, the connecting column 31 is then assembled onto the mounting column 11. This allows the sorting drive mechanism 2 to cooperate with the floating component 3 to form a modular assembly that is detachable from the sorting mechanism 1, effectively improving assembly efficiency and reducing the ease of maintenance and replacement of each module. In other embodiments, the sorting drive mechanism 2 can also be directly slidably mounted on the mounting column 11.

[0103] like Figures 12 to 14 As shown, in this embodiment, the rotation axis of the connecting column 31 is coaxial with the mounting shaft 146, so that the rotation axis of a set of guide wheels in the up-and-down walking guide assembly 14 is coaxial with the rotation axis of the connecting column 31. This allows the rotation of the guide wheels to be consistent with the rotation of the connecting column 31, further improving the consistency of the sorting drive mechanism 2 and the active sorting mechanism 1a when turning.

[0104] To simplify the installation of the connecting column 31, in this embodiment, both ends of the connecting column 31 are fixedly connected to the mounting shafts 146 of the upper and lower sets of walking guide components 14, respectively. This allows the connecting column 31 to rotate with the mounting shafts 146, and the rotation of the mounting shafts 146 directly drives the connecting column 31 to rotate, thereby driving the sorting drive mechanism 2 to rotate. This allows the drive wheels of the sorting drive mechanism 2 to travel better on the arc-shaped travel track 202, ensuring the operational stability and reliability of the sorting device 100 while simplifying the structure of the sorting drive mechanism 2. In other embodiments, both ends of the connecting column 31 can be directly rotatably mounted on the mounting column 11 and separated from the walking guide components 14.

[0105] Furthermore, both ends of the connecting column 31 are connected to the front mounting shafts 146a of the two walking guide wheel sets, respectively. This avoids interference between the connecting column 31 and the linkage 5, and also facilitates the consistency of the turning of the sorting drive mechanism 2 with the turning of the front side of the active sorting head, thereby better ensuring the smoothness of the turning of the sorting drive mechanism 2. Specifically, the end of the front mounting shaft 146a away from the wheel seat 142 passes through the mounting base 141 and is connected to the connecting column 31.

[0106] In this embodiment, the length of the connecting column 31 is adjustable, thereby allowing the length of the connecting column 31 to better adapt to the spacing between the mounting seats 141 of the two walking guide components 14, improving installation convenience and stability. Specifically, the connecting column 31 includes a column body 311 and a fixed seat 312. The column body 311 extends vertically, and its first end is slidably connected to the fixed seat 312 in the vertical direction. Its second end is connected to the sorting mechanism 1. The end of the fixed seat 312 away from the column body 311 is connected to the sorting mechanism 1, and the sorting drive mechanism 2 is mounted on the column body 311. This arrangement avoids the length adjustment of the connecting column 31 from affecting the installation of the sorting drive mechanism 2 on the connecting column 31. Specifically, the ends of the fixed seat 312 and the column body 311 away from the fixed seat 312 are respectively connected to two mounting shafts 146.

[0107] To improve the ease of connection between the fixed base 312 and the sorting mechanism 1 and the column 311, the fixed base 312 includes a fixed plate portion 3121 and an adjusting column portion 3122 connected to the fixed plate portion 3121. The fixed plate portion 3121 is connected to the mounting shaft 146, and the extending direction of the adjusting column portion 3122 is the same as the extending direction of the column 311. The adjusting column portion 3122 and the column 311 are slidably connected.

[0108] Preferably, the column 311 and the adjusting column portion 3122 are slidably fitted together to improve the stability and reliability of the sliding connection. One of the column 311 and the adjusting column portion 3122 has an adjusting hole 3111, and the other has a protruding guide component 35. The adjusting hole 3111 extends vertically, and the guide component 35 slides through the adjusting hole 3111. This allows for sliding guidance between the two components through the cooperation of the adjusting hole 3111 and the guide component 35, while also limiting the maximum relative sliding stroke of the column 311 and the adjusting column portion 3122, preventing relative separation during assembly and improving the stability and reliability of the connecting column 31. In other embodiments, other existing structures for sliding guidance and limiting can also be provided between the column 311 and the adjusting column portion 3122.

[0109] The column 311 is preferably a hollow structure to reduce the weight of the connecting column 31. The cross-section of the column 311 and the adjusting column 3122 is preferably rectangular, so that the column 311 and the adjusting column 3122 can be made of square profiles, reducing the processing difficulty and improving the ease of cooperation between the column 311 and the sorting drive mechanism 2. Adjustment holes 3111 are provided on at least two opposite sides of the column 311 to ensure the sliding stability and reliability of the adjusting column 3122 and the column 311.

[0110] Furthermore, the guide component 35 can slide within the adjustment hole 3111 while also locking the column 311 and the adjustment column portion 3122 after adjustment, to ensure the overall structural stability of the connecting column 242. Optionally, the guide component 35 can be a screw threaded onto the adjustment column portion 3122 or a bolt passing through the adjustment column portion 3122, or a pin structure passing through the two opposing adjustment holes 3111. This embodiment does not limit the specific type of pin.

[0111] The end of the column 311 away from the fixed base 312 is connected to a fastening plate 313. The fastening plate 313 is detachably connected to the mounting shaft 146 of the corresponding end of the travel guide assembly 14 to improve the connection stability and convenience between the column 31 and the mounting base 141. The limiting buffer 8 is connected to the lower end of the fastening plate 313.

[0112] In this embodiment, both the upper and lower ends of the column are provided with fixing shaft holes. The fixing shaft holes are non-circular holes. One end of the mounting shaft 146 is inserted into the fixing shaft hole, and the cross-sectional shape of this end is adapted to the shape of the fixing shaft hole to prevent relative rotation between the connecting column 31 and the mounting shaft 146. Specifically, the fixing shaft holes are provided on the fastening plate 313 and the fixing plate portion 3121.

[0113] like Figure 15 and Figure 16 As shown, the sorting drive mechanism 2 includes a mounting plate 21, a traveling wheel 22 rotatably mounted on the mounting plate 21, and a traveling drive assembly 23 that drives the traveling wheel 22 to rotate. The mounting plate 21 is slidably mounted on the connecting column 31. The traveling wheel 22 and the traveling drive assembly 23 are both located on the side of the mounting plate 21 away from the connecting column 31 to reduce the probability of interference between the traveling wheel 22 and the traveling drive mechanism and the connecting column 31. The traveling wheel 22 is located on the side of the connecting column 31 away from the mounting column 11. The traveling wheel 22 travels on the travel track 202.

[0114] To improve the smoothness of the sliding of the sorting mechanism 1 along the connecting column 31, the floating component 3 includes a sliding guide component. The sliding guide component includes a slidingly engaged floating guide rail 32 and a guide slider 33. One of the guide slider 33 and the floating guide rail 32 is connected to the connecting column 31, and the other is connected to the mounting plate 21, which extends vertically. In this embodiment, the floating guide rail 32 is disposed on the mounting plate 21, and the guide slider 33 is connected to the connecting column 31, thereby improving the ease of setting up the floating guide rail 32 and facilitating the installation of multiple floating guide rails 32. In other embodiments, the floating guide rail 32 can also be directly disposed on the connecting column 31.

[0115] In this embodiment, two sliding guide components are spaced apart horizontally, with the two sliding guide components located on opposite sides of the connecting column 31, to improve the sliding stability and reliability of the sorting drive mechanism 2 along the connecting column 31. Furthermore, each floating guide rail 32 is provided with at least two guide sliders 33 spaced apart, thereby further improving the floating stability and reliability of the sorting drive mechanism 2.

[0116] To improve the ease of connection between the guide slider 33 and the connecting column 31, the floating assembly 3 includes a connector 34. The connector 34 connects the guide slider 33 and the connecting column 31, thereby fixing the guide slider 33 relative to the connecting column 31. Furthermore, the connector 34 extends along the width direction of the mounting plate 21, and its middle portion is connected to the connecting column 31. Both ends of the connector 34 are respectively connected to a guide slider 33 of each of the two sliding guide assemblies. This ensures the synchronous operation of the two sliding guide assemblies, thereby better preventing the sorting drive mechanism 2 from deviating from the connecting column 31 and improving its stress stability and balance. The connector 34 is preferably a plate-like structure to improve the ease of connection between the connector 34 and the connecting column 31 and the guide slider 33.

[0117] In this embodiment, two walking wheels 22 are arranged at intervals in the vertical direction. The two walking wheels 22 are a drive wheel 22a and a follower wheel 22b. The walking drive assembly 23 drives the drive wheel 22a to rotate. The walking wheels 22 drive the follower wheel 22b to rotate as they travel along the travel track 202. This can reduce the driving cost and improve the stability and reliability of the sorting drive mechanism 2 traveling along the travel track 202.

[0118] The follower wheel 22b is vertically floatingly mounted on the mounting plate 21. The sorting drive mechanism 2 also includes an elastic element 25, which constantly applies a force to the follower wheel 22b toward the drive wheel 22a. This ensures that the drive wheel 22a and the follower wheel 22b remain stably pressed against the travel track 202, increasing friction between the travel wheel 22 and the travel track, preventing slippage, and increasing the upper limit of acceleration. In this embodiment, the follower wheel 22b is located below the drive wheel 22a; in other embodiments, the drive wheel 22a may be located below the follower wheel 22b.

[0119] like Figure 17 and Figure 18As shown, to improve the floating convenience of the follower wheel 22b, the sorting drive mechanism 2 also includes a floating seat 24. The floating seat 24 is vertically and floatingly mounted on the mounting plate 21 relative to the mounting plate 21. One end of the axle of the follower wheel 22b is mounted on the floating seat 24, and the other end of the axle is slidably inserted into the mounting plate 21, so that the wheel body of the follower wheel 22b is sandwiched between the mounting plate 21 and the floating seat 24. The elastic member 25 is vertically arranged, and the first end of the elastic member 25 abuts against the floating seat 24, and the second end of the elastic member 25 is connected to the mounting plate 21 to improve the ease of setting the elastic member 25.

[0120] The floating seat 24 includes a floating seat 24 and connecting columns 242. A floating plate 241 is opposite to and spaced apart from the mounting plate 21. A follower wheel 22b is mounted on the floating plate 241. The first end of the connecting column 242 is connected to the floating plate 241. A floating hole 211 is provided on the mounting plate 21. The floating hole 211 is an elongated hole extending vertically. The second end of the connecting column 242 is slidably inserted into the floating hole 211. At least two connecting columns 242 are spaced apart laterally, and the two connecting columns 242 are located on opposite sides of the follower wheel 22b. The floating holes 211 and the connecting columns 242 are arranged in a one-to-one correspondence to improve the floating stability and reliability of the floating seat 24.

[0121] To improve the ease of installation of the elastic element 25, a connecting plate 27 is connected to the side of the mounting plate 21 away from the drive wheel 22a. The second end of the elastic element 25 abuts against the connecting plate 27 to provide support for the connecting plate 27. Furthermore, the position of the connecting plate 27 relative to the mounting plate 21 in the vertical direction can be adjusted to adjust the distance between the connecting post 242 and the connecting plate 27, thereby adjusting the preload of the elastic element 25.

[0122] In this embodiment, a connecting boss protrudes from one side of the mounting plate 21, and an adjusting bolt 210 passes through the connecting boss. A fastening hole is provided on the connecting plate 27, and the adjusting bolt 210 passes through the fastening hole. A locking nut is provided on the adjusting bolt 210, and the locking nut abuts against the side of the connecting plate 27 away from the connecting boss. Thus, the distance between the connecting boss and the connecting plate 27 can be adjusted by rotating the adjusting nut, thereby adjusting the position of the connecting plate 27 relative to the mounting plate 21 in the vertical direction.

[0123] The connecting plate 27 includes a main plate portion. Sliding portions protrude from both sides of the main plate portion along its length towards the mounting column 11. These sliding portions are L-shaped and form grooves with the main plate portion. The opposite sides of the mounting plate 21 are slidably inserted into these grooves. This arrangement facilitates guidance for the sliding of the connecting plate 27 on the mounting plate 21, improving adjustment stability. However, it is understood that other existing structures capable of vertically adjusting the height of the connecting plate 27 relative to the mounting plate 21 can also be applied to this embodiment.

[0124] In this embodiment, the first end of the elastic element 25 abuts against the connecting post 242, and the elastic element 25 and the connecting post 242 are arranged in a one-to-one correspondence to improve the force balance and force stability of the floating seat 24, and save the space occupied by the entire sorting drive mechanism 2. Specifically, a first guide post 28 is connected to the connecting post 242, and a second guide post 29 is connected to the connecting plate 27. Both the first guide post 28 and the second guide post 29 extend in the vertical direction. The two ends of the elastic element 25 are respectively sleeved on the first guide post 28 and the second guide post 29 to limit the direction of elastic deformation of the elastic element 25.

[0125] In this embodiment, the sorting drive mechanism 2 also includes a pressure wheel 26. One pressure wheel 26 is provided on each of the two opposite sides of the follower wheel 22b. The pressure wheel 26 is mounted on the floating seat 24 to cooperate with the follower wheel 22b to press the drive wheel 22a, thereby improving the pressing effect on the drive wheel 22a and further improving the operational reliability of the sorting drive mechanism 2.

[0126] The mounting plate 21 has a first shaft hole 212, and the floating plate 241 has a second shaft hole 2411. Both the first shaft hole 212 and the second shaft hole 2411 are elongated holes extending vertically. The first shaft hole 212 and the second shaft hole 2411 are each corresponding to a pressure wheel 26. The first end of the axle of the pressure wheel 26 is inserted into the first shaft hole 212, and the other end is inserted into the second shaft hole 2411. The two pressure wheels 26 are used to abut against the travel track 202 to keep the sorting drive mechanism 2 running horizontally along the travel track 202.

[0127] The sorting drive mechanism 2 also includes a connecting seat, which is connected to the side of the mounting plate 21 away from the mounting column 11. The drive wheel 22a is sandwiched between the connecting seat and the mounting plate 21. The walking drive assembly 23 is mounted on the connecting seat and connected to the axle of the drive wheel 22a to drive the drive wheel 22a to rotate. The walking drive assembly 23 is located on the side of the connecting seat away from the walking wheel 22 to avoid interference between the walking drive assembly 23 and the connecting column 31. The walking drive assembly 23 can adopt existing structures for driving the walking wheel 22 to rotate, such as a geared motor. This embodiment does not limit or elaborate on the specific structure of the walking drive assembly 23.

[0128] like Figure 19 and Figure 20As shown, the loading platform 12 can be a tipping platform or a belt-driven platform. The tipping platform 12 has a recessed bearing surface, which is effective for sorting rolling items. The belt-driven platform 12 can have raised ridges added to the belt surface, making it suitable for sorting thin and light items. Existing technologies that enable loading and unloading of the loading platform 12 can all be applied to this embodiment. This embodiment does not limit or elaborate on the structure of the loading platform 12 or the lifting mechanism that drives the lifting of the loading platform 12.

[0129] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
