Abstract
Description
Technical Field
[0001] This application claims the priority of a Chinese patent application with the application number 202310794287.9 and the invention title of "Sorting Module and Sorting Device", which was filed with the Chinese Patent Office on June 29, 2023, and the entire content thereof is incorporated herein by reference.
[0002] This application relates to the technical field of logistics sorting, and particularly to a sorting module and a sorting device.
Background Art
[0003] Currently, the commercially available sorting brackets have a simplified structure, are convenient for production, and their shape presents a "U" - shaped design. The transmission mechanism usually includes structures such as a shaft rod and a gear externally fitted on the shaft rod. When installing the transmission mechanism into the sorting bracket, usually, first, structures such as the gear are externally fitted on the shaft rod, and then the entire shaft rod is inserted into the sorting bracket from top to bottom. Through - holes are provided on the side plates of the sorting bracket. Align both ends of the shaft rod with the through - holes, and then fix and screw the shaft rod and the sorting bracket by screwing.
[0004] However, in such a connection method, usually, the hole diameter of the through - hole is set larger than the diameter of the screw. After fixing the shaft rod and the sorting bracket, the positions of the screws at both ends of the shaft rod in the through - hole change, the connection between the shaft rod and the sorting bracket becomes unstable, and the axis of the shaft rod does not become perpendicular to the side plate. As a result, the shaft rods of two adjacent transmission mechanisms are not parallel, and when the transmission gears externally fitted on the adjacent shaft rods are meshed, the positions of the teeth of the gears are shifted, that is, the meshed gears are not located in the same plane, and an abnormal meshing situation called "trapezoidal meshing" occurs when they are meshed, which will affect the service life of the gears.

[0040] This application provides an embodiment of a sorting module, which is mainly used in a sorting device. The sorting device is a sorting machine commonly used in existing logistics transportation, and mainly comprises a sorting module and a platform assembly, transporting goods by the rotation of a group of rollers in the sorting module, and controlling the direction of transport of the goods by the rotation of the entire sorting module, thereby achieving the purpose of sorting goods. The number of sorting modules in the sorting device is usually set to be multiple, with multiple sorting modules installed in an array, and the sorting module includes a sorting bracket and a base, the base is used to be fixedly connected to the chassis of the sorting device, the sorting bracket is attached to the base and is rotatable relative to the base, a transmission mechanism is installed inside the sorting bracket and base, and a group of rollers is attached to the sorting bracket and is transmitted and connected to the transmission mechanism, thereby making the group of rollers rotatable.
[0041] Referring to Figures 1-8, in one embodiment of the present application, the sorting module 10 is used in a sorting device, and the sorting module 10 includes a sorting bracket 100, a mounting opening 200, a transmission mechanism 300, and a position limiting structure 400, the sorting bracket 100 includes a bottom plate 110 and two side plates 120 provided on opposite sides of the bottom plate 110, the mounting opening 200 is provided corresponding to each of the two side plates 120, and the mounting opening 200 includes a first mounting opening 210 and a second mounting opening 220 that are in communication with each other, and the transmission The moving mechanism 300 includes a shaft 310 attached to the first mounting opening 210, the shaft 310 being fixed to the first mounting opening 210, the first mounting opening 210 having a first direction into which the shaft 310 enters, the shaft 310 and two opposing side walls of the first mounting opening 210 contact each other in a second direction to restrict its position, the position restricting structure 400 is provided in the second mounting opening 220 so as to contact the shaft 310 in the first direction to restrict its position, where the first direction intersects with the second direction.
[0042] Referring to Figure 4, the sorting bracket 100 includes a base plate 110 and two side plates 120 provided on opposite sides of the base plate 110, with a mounting space formed between the two side plates 120 for mounting the transmission mechanism 300 of the sorting module 10. The side plates 120 and the base plate 110 are fixedly connected by screws 500, but they may be connected by other means. To facilitate production and processing, the sorting bracket 100 of this application is integrally molded, and is formed by primary processing of sheet metal members, resulting in a simple structure, ease of processing, further increasing the production efficiency of the sorting bracket 100 and reducing production costs. In addition, there is no need for secondary processing after the processing of the sorting bracket 100 of this application is completed, making the production process simpler and easier and increasing production efficiency. The material cost of the sorting bracket 100 manufactured from sheet metal members is relatively low, further reducing costs.
[0043] Referring to Figures 4 and 5, the two side plates 120 are each provided with corresponding first mounting openings 210 and second mounting openings 220 that communicate with each other. The shape of the first mounting opening 210 and / or the second mounting opening 220 may be elongated, curved, have a bent portion, or have any other shape, and is not specifically limited thereto. To facilitate processing and manufacturing, the shape of the opening is usually set to a square or circular shape with regular edges, and in this embodiment, both the first mounting opening 210 and the second mounting opening 220 are installed in an elongated shape.
[0044] Referring to Figures 2 and 7, both ends of the shaft 310 are respectively attached to the first mounting openings 210 of the two side plates 120, and the shaft 310 is fixed to the first mounting openings 210 and does not rotate itself. In the process of inserting the shaft 310 into the first mounting openings 210, the direction in which the shaft 310 is inserted is defined as the first direction, and after the shaft 310 is installed in the first mounting openings 210, at least a portion of the outer surface of the shaft 310 abuts against the two opposing side walls of the first mounting openings 210 so that the position of the shaft 310 installed in the first mounting openings 210 is restricted in the second direction.
[0045] On the other hand, a position-restricting structure 400 is provided in the second mounting opening 220, and this position-restricting structure 400 abuts against the shaft 310, thereby restricting the position of the shaft 310 in the first direction as well. In this way, the cooperation between the shaft 310 and the two opposing side walls of the first mounting opening 210, along with the position-restricting action of the position-restricting structure 400, restricts the position of the shaft 310 installed in the mounting opening 200, preventing the shaft 310 from moving. In this manner, the shaft 310 is installed in a preset position without coming loose, ensuring the stability of the connection between the shaft 310 and the sorting bracket 100. Furthermore, when two adjacent shafts 310 are fitted onto the transmission gear 320 and meshed, they are positioned on the same plane when meshing, ensuring the service life of the gear without any abnormal meshing conditions such as misalignment of the gear teeth or point contact meshing between gears.
[0046] The first direction intersects with the second direction, and the first direction may be horizontal, vertical, or inclined; however, it is not specifically limited to these directions.
[0047] The technical solution of this application involves fixing the position of the shaft 310 mounted in the first mounting opening 210 by restricting its position in both the intersecting first and second directions using the two opposing side walls of the first mounting opening 210 and the position limiting structure 400. This prevents the shaft 310 from being displaced relative to the sorting bracket 100, ensuring the stability of the connection between the shaft 310 and the sorting bracket 100. This avoids an abnormal meshing situation called "trapezoidal meshing" that occurs when two adjacent shafts 310 are meshed, where the teeth are misaligned, meaning the meshed gears are not located on the same plane, thus ensuring the service life of the gears.
[0048] Referring to Figures 2, 3, and 7-10, in one embodiment, the shaft 310 includes a main body 311 and projections 312 that protrude outward from both ends of the main body 311. A first stepped surface 313 is formed between the main body 311 and the projections 312, located on the end face of the main body 311. The projections 312 are provided in the first mounting opening 210, and the first stepped surface 313 abuts against the inner wall surface of the side plate 120.
[0049] Referring to Figure 10, the shaft 310 includes a rod-shaped main body 311 and projections 312 that protrude outward from the end faces of both ends in the longitudinal direction of the main body 311. The projections 312 are formed by partially protruding outward from the middle of the end face of the main body 311, and the center point of the structure of the projections 312 coincides with the axis of the main body 311. Because the projections 312 are formed by partially protruding outward from the middle of the end face of the main body 311, there is a first stepped surface 313 between the main body 311 and the projections 312, and the first stepped surface 313 is the end face of the main body 311 when the projections 312 are not protruding. The projections 312 can be set to have a more regular shape so that their position is more appropriately restricted by the opposing side walls of the first mounting opening 210.
[0050] In the radial direction of the shaft rod 310, the cross-section of the projection 312 is set to be a rectangle. The rectangle is approximately square, and for ease of processing and for the sake of perfection, all four sides of the rectangle are chamfered. Of course, in other embodiments, the shape of the cross-section of the projection 312 may be circular, triangular, trapezoidal, or other shapes, and is not specifically limited thereto.
[0051] Referring to Figures 7 and 8, the first stepped surface 313 abuts against the inner wall surface of the side plate 120, and by installing it in this manner, the axial position of the shaft rod 310 can be restricted. At the same time, when connecting the shaft rod 310 and the sorting bracket 100 with the screw 500, overtightening can deform the sorting bracket 100 (i.e., the two side plates 120 of the sorting bracket 100 deform inward), thereby preventing the teeth from being misaligned when gears on multiple transmission shafts are meshed together, that is, preventing the gears that are meshing with each other from being located on the same plane, and thus avoiding a situation called "trapezoidal meshing" when they are meshed, thereby ensuring the lifespan of the gears.
[0052] The end face of the projection 312 is flush with the outer wall surface of the side plate 120. Specifically, if the end face of the projection 312 is provided to protrude from the outer wall surface of the side plate 120, it becomes inconvenient to fix it, requiring a connecting member that matches the shape of the projection, which increases costs. If the end face of the projection 312 is not provided to protrude from the outer wall surface of the side plate 120 and is not flush with the outer wall surface of the side plate 120, there is a risk that the projection 312 will escape from the mounting opening 200 of the side plate 120, affecting the connection between the shaft rod 310 and the sorting bracket 100. In particular, if the side plate 120 deforms outward, the situation in which the projection 312 escapes from the mounting opening 200 of the side plate 120 is more likely to occur. Therefore, the end face of the projection 312 is made flush with the outer wall surface of the side plate 120.
[0053] Referring to Figures 4 and 5, in one embodiment, the first mounting opening 210 includes an insertion opening 211 and a position limiting opening 212 that are in communication with each other, the insertion opening 211 is used so that the projection 312 enters the position limiting opening 212, and the second mounting opening 220 penetrates two opposing side walls of the insertion opening 211.
[0054] When installing the shaft 310, first insert both ends of the shaft into the insertion openings 211, respectively, to restrict the position of the shaft 310 in the first direction, and then move the projection 312 from the insertion opening 211 into the position restriction opening 212. The second mounting opening 220 penetrates the two opposing side walls of the insertion opening 211, and the position restriction structure 400 is placed in the second mounting opening 220, thereby restricting the position of the shaft 310 in the second direction.
[0055] Referring to Figures 4 and 5, in one embodiment, in the first direction, the height of the insertion opening 211 is higher than the height of the position limiting opening 212. By setting it in this way, both ends of the shaft 310 can be easily inserted into the insertion opening 211, and sufficient movement space is secured for the projection 312 to move into the position limiting opening 212 and limit its position.
[0056] Referring to Figures 4 and 5, in one embodiment, the distance between the two side walls of the insertion opening 211 in a direction perpendicular to the first direction is greater than the diameter of the shaft 310. Specifically, by setting the distance between the two side walls of the insertion opening 211 to be greater than the diameter of the shaft 310, the shaft 310 can pass through the insertion opening 211. When installing the shaft 310, one end of the shaft 310 is passed through the insertion opening 211, and the other end is moved downward into the insertion opening 211 of the other side plate 120. After that, the projection 312 is moved from the insertion opening 211 into the position limiting opening 212 to limit its position, making installation convenient and quick.
[0057] Referring to Figures 4 and 5, in one embodiment, the cross-sectional area of the insertion opening 211 in the axial direction of the shaft 310 is 1 to 3 times the cross-sectional area of the position restriction opening 212. Specifically, by setting the cross-sectional area of the insertion opening 211 in the axial direction of the shaft 310 to 1 to 3 times the cross-sectional area of the position restriction opening 212, it is possible to ensure that the cross-sectional area of the insertion opening 211 is sufficiently larger than the cross-sectional area of the position restriction opening 212, and the shaft 310 can be easily installed in the mounting opening 200.
[0058] Continuing to refer to Figures 4 and 5, in one embodiment, in the first direction, the height of the second mounting opening 220 is lower than the height of the position limiting opening 212. Specifically, the second mounting opening 220 is mainly used to mount the position limiting structure 400 so as to limit the position of the shaft 310 in the first direction. The position limiting principle of the position limiting structure 400 is that its two opposing surfaces contact both the projection 312, which is mounted so as to be limited in position within the position limiting opening 212, and the inner wall surface of the second mounting opening 220, thereby preventing the projection 312 from displacing in the first direction and limiting the position of the shaft 310 in the first direction. By setting the height of the second mounting opening 220 lower than the height of the position restriction opening 212, it is possible to restrict the position of the shaft rod 310 simply by using a position restriction structure 400 that is not tall (i.e., thin), thus reducing the requirements for the position restriction structure 400, while ensuring that a sufficient portion of the projection 312 is positioned within the position restriction opening 212, thereby ensuring the position restriction effect of the two opposing side walls of the position restriction opening 212 relative to the projection 312 in the second direction.
[0059] Referring to Figures 4 and 5, in one embodiment, the second mounting opening 220 extends along a second direction, and in the second direction, the length of the second mounting opening 220 is greater than the width of the insertion opening 211 and the position limiting opening 212. Specifically, the second mounting opening 220 can extend along a second direction, and in the second direction, the second mounting opening 220 penetrates the side wall of the insertion opening 211, ensuring that the length of the second mounting opening 220 is sufficiently long. As a result, the position limiting structure 400 installed in the second mounting opening 220 can completely cover the projection 312 installed in the position limiting opening 212, thereby limiting the position of the shaft 310 in the first direction.
[0060] Referring to Figures 5, 7 to 10, in one embodiment, a second stepped surface 314 is further formed between the main body 311 and the projection 312, the first mounting opening 210 has a bottom wall 212a downstream in the first direction, the second stepped surface 314 is located on the side of the projection 312 away from the bottom wall 212a, and the maximum distance from the second stepped surface 314 to the end face of the projection 312 is greater than the maximum distance from the first stepped surface 313 to the end face of the projection 312.
[0061] Since the main body portion 311 of the shaft 310 is a rod-shaped cylindrical body, and the projections 312 extending outward from both ends of the projections 312 are substantially rectangular, a stepped surface is formed between the projections 312 and the main body portion 311. The stepped surface can be broadly divided into four stepped surfaces corresponding to the four sides of the projections 312. These four stepped surfaces may be connected at their ends to form a single annular stepped surface, or they may be separated from each other to form four independent stepped surfaces. Furthermore, two or three adjacent stepped surfaces may be connected from end to end, and this is not specifically limited. In this embodiment, the stepped surface can be specifically divided into a first stepped surface 313 and a second stepped surface 314. The first stepped surface 313 abuts against the inner wall surface of the side plate 120 and mainly serves to restrict the axial position of the shaft 310. The maximum distance from the second stepped surface 314 to the end face of the projection 312 is greater than the maximum distance from the first stepped surface 313 to the end face of the projection 312. In other words, the second stepped surface 314 is sufficiently deep in the axial direction of the shaft rod 310, and the second stepped surface 314 is located on the side of the projection 312 away from the bottom wall 212a. That is, in the axial direction of the shaft rod 310, the projection of the second stepped surface 314 at least partially overlaps with the second mounting opening 220. As a result, the position limiting structure 400 installed in the second mounting opening 220 can be inserted to a sufficient depth, at least longer than the length of the projection 312, thereby ensuring the position limiting effect of the position limiting structure 400 on the shaft rod 310 in the first direction.
[0062] Referring to Figures 2 and 3, in one embodiment, the position limiting structure 400 includes a connecting portion 410 and a position limiting portion 420 connected to one end of the connecting portion 410. The position limiting portion 420 is inserted into the second mounting opening 220 and abuts against the outer wall surface of the projection 312 and the inner wall surface of the second mounting opening 220, respectively. The connecting portion 410 is used to connect to the projection 312. Specifically, the position limiting structure 400 is provided in a substantially L-shape, has a simple structure, and is easy to manufacture. The position limiting structure 400 is divided into a position limiting portion 420 inserted into the second mounting opening 220 and a connecting portion 410 fixed relative to the sorting bracket 100. The position limiting structure 400 can be formed by bending a single sheet metal member, and is easy to process. After the position limiting portion 420 is inserted into the second mounting opening 220, it comes into contact with the outer wall surface of the projection 312 and the inner wall surface of the second mounting opening 220, respectively. This prevents the shaft rod 310 from moving relative to it in the first direction, and limits the position of the shaft rod 310 by contact in the first direction.
[0063] Referring to Figures 2, 3, 8, and 10, in one embodiment, a screw hole 312a is provided on the outer end surface of the projection 312, and a through hole 411 is provided in the connecting portion 410 through which a screw 500 passes, and the screw 500 passes through the through hole 411 and is screwed into the screw hole 312a. Specifically, the first through hole 411 can be directly provided in the connecting portion 410 so that the screw 500 passes through and is screwed into the screw hole 312a in the projection 312 of the shaft rod 310. This fixes the position of the position limiting structure 400, simplifies the connection method, and further ensures that the shaft rod 310 does not displace at the mounting opening 200 by fixing the position limiting structure 400 relative to both the sorting bracket 100 and the shaft rod 310 with the screw 500. Of course, in other embodiments, the position limiting structure 400 can be fixed to the sorting bracket 100 by providing a hole in the sorting bracket 100 for fixing the position limiting structure 400, thereby ensuring the position limiting effect of the position limiting structure 400 on the shaft 310, or the position limiting structure 400 may be fixed by other connection methods, and this is not specifically limited.
[0064] Referring to Figure 8, as considered here, if the length to which the position limiting portion 420 is inserted into the second mounting opening 220 is insufficient, for example, if the length to which the position limiting portion 420 is inserted into the second mounting opening 220 is less than the thickness of the side plate 120, then when the sorting module 10 vibrates or the sorting bracket 100 deforms, the position limiting portion 420 is likely to detach from the second mounting opening 220, and will not be able to perform a position limiting action on the shaft 310 in the first direction, allowing the shaft 310 to move in the first direction. In view of this, in order to solve this problem, the length to which the position limiting portion 420 is inserted into the second mounting opening 220 is set to be greater than the thickness of the side plate 120.
[0065] Referring to Figures 3, 8, and 10, the end of the projection 312 is chamfered in accordance with the connection point between the position limiting portion 420 and the connecting portion 410. Specifically, the position limiting structure 400 is formed by bending a sheet metal member to create the position limiting portion 420 and the connecting portion 410, and therefore the connection point between the connecting portion 410 and the position limiting portion 420 is an arc-shaped transition surface. In order to avoid interference between the end of the projection 312 corresponding to the connection point between the position limiting portion 420 and the connecting portion 410 and the position limiting structure 400, it is chamfered, thereby allowing the position limiting structure 400 to be in close contact with the outer surface of the projection 312.
[0066] In one embodiment, the angle between the first direction and the second direction is in the range of 45° to 135°. Specifically, the angle between the first direction and the second direction can be set within the range of 45° to 135°, and within this range, it is possible to ensure that the position of the shaft rod 310 mounted in the first mounting opening 210 is restricted in both the first and second directions. In this embodiment, the first direction is the extending direction of the first mounting opening 210, and the second direction is the extending direction of the second mounting opening 220.
[0067] In one embodiment, the first direction is perpendicular to the second direction. That is, the extending direction of the first mounting opening 210 is perpendicular to the extending direction of the second mounting opening 220, making it easier to process the vertically positioned first mounting opening 210 and second mounting opening 220, and allowing the position limiting structure 400 installed in the second mounting opening 220 to cooperate better with the projection 312 installed in the first mounting opening 210 in order to limit the position of the shaft rod 310 in the first direction.
[0068] In one embodiment, the first mounting opening 210 extends vertically, and the second mounting opening 220 extends horizontally. The first and second mounting openings 210 and 220, which extend vertically and horizontally, are easy to manufacture, and the shaft rod 310 installed in the first mounting opening 210 can be locked and its position restricted by the position restriction opening 212 at the bottom of the first mounting opening 210. On the other hand, because the first mounting opening 210 extends vertically, it is also convenient to insert the shaft rod 310 into the first mounting opening 210 and install the shaft rod 310.
[0069] Referring to Figures 1, 6, and 9, in one embodiment, the transmission mechanism 300 further includes a transmission gear 320, the sorting module 10 further includes a roller group 600, the transmission gear 320 is rotatably mounted on the shaft 310, the roller group 600 is mounted on the sorting bracket 100, the roller group 600 has a roller gear 610, and the transmission gear 320 meshes with the roller gear 610.
[0070] A transmission gear 320 is rotatably fitted onto a shaft 310, and a mounting position for attaching a roller group 600 may be provided on the sorting bracket 100. The roller gear 610 of the roller group 600 meshes with the transmission gear 320, and when the transmission gear 320 rotates, it drives the roller gear 610 to rotate, thereby making the roller group 600 rotatable and enabling the transport of cargo passing through the roller group 600. The transmission gear 320 is provided at one end of the shaft 310, and a blocking step and an annular locking groove 315 are provided on the shaft 310. The blocking step restricts the position of one side of the transmission gear 320, and a locking ring is provided in the annular locking groove 315 to restrict the position of the other side of the transmission gear 320.
[0071] Referring to Figures 6, 7, and 9, in one embodiment, the transmission mechanism 300 further includes a bearing 330, the bearing 330 including a bearing inner ring, a bearing outer ring, and bearing balls positioned between the bearing inner ring and the bearing outer ring, the bearing inner ring being fitted onto and fixed to the shaft 310, and the bearing outer ring being connected to the transmission gear 320.
[0072] The inner ring of the bearing is fitted onto the shaft 310 and fixed to the shaft 310, and the transmission gear 320 is fitted onto the outer ring of the bearing and fixed relative to it. An active mechanism 800 may be provided on one side of the transmission mechanism 300, and the active mechanism 800 provides power to the transmission mechanism 300. The transmission gear 320 meshes with the active gear 810 of the active mechanism 800, and when the active gear 810 rotates, it drives the transmission gear 320 to rotate, which in turn drives the roller gear 610 to rotate, causing the roller group 600 to rotate on its own and transport the load passing through the roll group 600.
[0073] Referring to Figure 1, in one embodiment, the sorting module 10 further includes a base 700, the sorting bracket 100 is rotatably mounted on the base 700, and the base 700 is used to fixably connect to the machine table of the sorting device. Specifically, the sorting module 10 is fixedly mounted to the machine table of the sorting device by the base 700, the sorting bracket 100 is rotatable relative to the base 700, and the roller group 600 is attached to and fixed relative to the sorting bracket 100. When the sorting bracket 100 rotates, it drives the roller group 600 to rotate, thereby controlling the transport direction of the goods passing through the roller group 600. Typically, the sorting device includes a plurality of sorting modules 10, and the plurality of sorting modules 10 are installed in multiple rows and multiple columns. The bottom plate 110 of the sorting bracket 100 is provided with connection holes for connecting connecting rods. A single row or single column sorting bracket 100 can be connected by a single connecting rod, allowing the entire sorting bracket 100 to rotate when the connecting rod moves. This connection method can be implemented by driving the connecting rod with only one motor, reducing the number of motors used and significantly lowering costs. In addition, this connection method is simple, easy to operate, and easy to install, improving production efficiency.
[0074] Referring to Figures 1 to 10, the present application further provides a sorting module 10, in one embodiment of the present application, the sorting module 10 is used in a sorting device, and the sorting module 10 includes a sorting bracket 100, a mounting opening 200, a transmission mechanism 300, a position limiting structure 400 and a group of rollers 600. The sorting bracket 100 includes a bottom plate 110 and two side plates 120 provided on opposite sides of the bottom plate 110, the mounting opening 200 is provided corresponding to each of the two side plates 120, and the mounting opening 200 includes a first mounting opening 210 and a second mounting opening 220 communicating with each other, the first mounting opening 210 extending along the vertical direction and the second mounting opening 220 extending along the horizontal direction. The transmission mechanism 300 includes a shaft 310, a bearing 330, and a transmission gear 320, wherein the bearing 330 is fitted onto the shaft 310, and the transmission gear is fitted onto the bearing 330. The shaft 310 includes a main body 311 and projections 312 that are partially formed to protrude outward from the middle of the end faces of both ends of the main body 311. The first mounting opening 210 includes an insertion opening 211 that communicates with each other and a rectangular position The sorting bracket 100 includes a position restriction opening 212, the rectangular position restriction opening 212 is located below the insertion opening 211, the insertion opening 211 is used for the projection 312 to enter the rectangular position restriction opening 212, the rectangular position restriction opening 212 engages with the projection 312 horizontally to restrict its position, a first stepped surface 313 is formed between the main body 311 and the projection 312 on the end face of the main body 311, the first stepped surface 313 abuts against the inner wall surface of the side plate 120, the position restriction structure 400 is provided in the second mounting opening 220 and is used to abut against the shaft rod 310 vertically to restrict its position, the roller group 600 is provided in the sorting bracket 100, the roller group 600 has a roller gear 610, and the transmission gear 320 meshes with the roller gear 610.
[0075] Referring to Figure 4, the sorting bracket 100 includes a base plate 110 and two side plates 120 provided on opposite sides of the base plate 110, with a mounting space formed between the two side plates 120 for mounting the transmission mechanism 300 of the sorting module 10. The side plates 120 and the base plate 110 are fixedly connected by screws 500, but they may be connected by other means. To facilitate production and processing, the sorting bracket 100 of this application is integrally molded, and is formed by primary processing of sheet metal members, resulting in a simple structure, easy processing, further increasing the production efficiency of the sorting bracket 100 and reducing production costs. In addition, there is no need for secondary processing after the processing of the sorting bracket 100 of this application is completed, making the production and processing process easier and increasing production efficiency. The material cost of the sorting bracket 100 manufactured from sheet metal members is relatively low, further reducing costs.
[0076] Referring to Figure 5, the two side plates 120 are each provided with corresponding first mounting openings 210 and second mounting openings 220 that communicate with each other. The shape of the first mounting opening 210 and / or the second mounting opening 220 may be elongated, arc-shaped, have a bent portion, or be of any other shape, and is not specifically limited thereto. To facilitate processing and manufacturing, the shape of the opening is usually set to a square or circular shape with regular edges, and in this embodiment, both the first mounting opening 210 and the second mounting opening 220 are installed in an elongated shape. Furthermore, the first mounting opening 210 extends along the vertical direction, and the second mounting opening 220 extends along the horizontal direction. The first and second mounting openings 210 and 220, which extend vertically and horizontally, are easy to manufacture, and the shaft 310 installed in the first mounting opening 210 can be locked and its position restricted by the position restriction opening 212 at the bottom of the first mounting opening 210. On the other hand, because the first mounting opening 210 extends along the vertical direction, it is also convenient to insert the shaft 310 into the first mounting opening 210 and install the shaft 310.
[0077] Referring to Figures 7 to 10, the transmission mechanism 300 includes a shaft 310, a bearing 330, and a transmission gear 320. The transmission gear 320 is rotatably fitted onto the shaft 310, and the sorting bracket 100 may be provided with a mounting position for attaching a roller group 600. The roller gear 610 of the roller group 600 meshes with the transmission gear 320, and when the transmission gear 320 rotates, it drives the roller gear 610 to rotate, thereby making the roller group 600 rotatable and enabling the transport of cargo passing through the roller group 600. The bearing 330 includes a bearing inner ring, a bearing outer ring, and bearing balls positioned between the bearing inner ring and the bearing outer ring. The bearing inner ring is fitted onto the shaft 310 and fixed to the shaft 310. The transmission gear 320 is fitted onto the bearing outer ring and fixed relative to it. An active mechanism 800 may be provided on one side of the transmission mechanism 300, and the active mechanism 800 provides power to the transmission mechanism 300. The transmission gear 320 meshes with the active gear 810 of the active mechanism 800, and when the active gear 810 rotates, it drives the transmission gear 320 to rotate, which in turn drives the roller gear 610 to rotate, causing the roller group 600 to rotate on its own and transport the load passing through the roll group 600.
[0078] Referring to Figure 10, the shaft 310 includes a rod-shaped main body 311 and projections 312 that protrude outward from the end faces of both ends in the longitudinal direction of the main body 311. The projections 312 are formed by partially protruding outward from the middle of the end face of the main body 311, and the center point of the structure of the projections 312 coincides with the axis of the main body 311. Because the projections 312 are formed by partially protruding outward from the middle of the end face of the main body 311, there is a first stepped surface 313 between the main body 311 and the projections 312, and the first stepped surface 313 is the end face of the main body 311 when the projections 312 are not protruding. The projection 312 is placed inside the rectangular position-restricting opening 212, and the cooperation of the projection 312 and the two opposing side walls of the rectangular position-restricting opening 212 restricts the position of the shaft rod 310 in the horizontal direction. Furthermore, the shaft rod 310, which is installed inside the first mounting opening 210, is fixed to the first mounting opening 210 and does not rotate itself.
[0079] Referring to Figures 7 and 8, the first stepped surface 313 abuts against the inner wall surface of the side plate 120, and by installing it in this manner, the axial position of the shaft rod 310 can be restricted. At the same time, when connecting the shaft rod 310 and the sorting bracket 100 with the screw 500, overtightening can deform the sorting bracket 100 (i.e., the two side plates 120 of the sorting bracket 100 deform inward), thereby preventing the teeth from being misaligned when the gears on multiple transmission shafts are meshed together, that is, preventing the gears that are meshing with each other from being located on the same plane, and thus avoiding a situation called "trapezoidal meshing" when they are meshed together, thereby ensuring the lifespan of the gears.
[0080] Referring to Figures 2 and 3, a position-restricting structure 400 is provided in the second mounting opening 220, and this position-restricting structure 400 abuts against the shaft 310, thereby restricting the position of the shaft 310 in the vertical direction as well. In this way, the cooperation between the shaft 310 and the two opposing side walls of the first mounting opening 210, along with the position-restricting action of the position-restricting structure 400, restricts the position of the shaft 310 installed in the mounting opening 200, preventing the shaft 310 from moving. Thus, the shaft 310 is installed in a preset position without coming loose, ensuring the stability of the connection between the shaft 310 and the sorting bracket 100. Furthermore, when the transmission gears 320 fitted onto two adjacent shafts 310 mesh, they are located on the same plane, preventing abnormal meshing conditions such as misalignment of gear teeth or point contact meshing between gears, thus ensuring the service life of the gears.
[0081] Referring to Figures 2 to 5 and Figure 8, in one embodiment, the second mounting opening 220 penetrates two opposing side walls of the insertion opening 211, the height of the insertion opening 211 is higher than the height of the rectangular position limiting opening 212 in the vertical direction, the height of the second mounting opening 220 is lower than the height of the rectangular position limiting opening 212, and the distance between the two side walls of the insertion opening 211 is greater than the diameter of the shaft 310 in the horizontal direction.
[0082] Referring to Figure 5, the second mounting opening 220 penetrates the two opposing side walls of the insertion opening 211, and by placing the position limiting structure 400 inside the second mounting opening 220, the position of the shaft rod 310 can be limited in the second direction. In the vertical direction, the height of the insertion opening 211 is set higher than the height of the rectangular position limiting opening 212, and the height of the second mounting opening 220 is set lower than the height of the rectangular position limiting opening 212. By setting it in this way, both ends of the shaft rod 310 can be easily inserted into the insertion opening 211, and sufficient movement space is secured for the projection 312 to move into the position limiting opening 212 and limit its position. Furthermore, the shaft 310 can pass through the insertion opening 211, and when installing the shaft 310, one end of the shaft 310 is passed through the insertion opening 211, the other end is moved downward into the insertion opening 211 of the other side plate 120, and then the projection 312 is moved from the insertion opening 211 into the position limiting opening 212 to limit its position, making installation convenient and quick.
[0083] Referring to Figures 8 to 10, in one embodiment, a second stepped surface 314 is further formed between the main body portion 311 and the projection portion 312, the second stepped surface 314 is located on the side of the projection portion 312 away from the bottom of the first mounting opening 210, and the maximum distance from the second stepped surface 314 to the end face of the projection portion 312 is greater than the maximum distance from the first stepped surface 313 to the end face of the projection portion 312.
[0084] Since the main body portion 311 of the shaft 310 is a rod-shaped cylinder, and the projections 312 extending outward from both ends of the projections 312 are substantially rectangular, a stepped surface is formed between the projections 312 and the main body portion 311. The stepped surface can be broadly divided into four stepped surfaces corresponding to the four sides of the projections 312. These four stepped surfaces may be connected in order from end to end to form a single annular stepped surface, or they may be separated from each other to form four independent stepped surfaces. Furthermore, two or three adjacent stepped surfaces may be connected from end to end, and this is not specifically limited. In this embodiment, the stepped surface can be specifically divided into a first stepped surface 313 and a second stepped surface 314. The first stepped surface 313 abuts against the inner wall surface of the side plate 120 and mainly serves to restrict the axial position of the shaft 310. The maximum distance from the second stepped surface 314 to the end face of the projection 312 is greater than the maximum distance from the first stepped surface 313 to the end face of the projection 312. In other words, the second stepped surface 314 is sufficiently deep in the axial direction of the shaft rod 310, and the second stepped surface 314 is located on the side of the projection 312 away from the bottom wall 212a. That is, in the axial direction of the shaft rod 310, the projection of the second stepped surface 314 at least partially overlaps with the second mounting opening 220. As a result, the position limiting structure 400 installed in the second mounting opening 220 can be inserted to a sufficient depth, at least longer than the length of the projection 312, thereby ensuring the vertical position limiting effect of the position limiting structure 400 relative to the shaft rod 310.
[0085] Referring to Figures 1 to 3, in one embodiment, the position limiting structure 400 includes a connecting portion 410 and a position limiting portion 420 connected to one end of the connecting portion 410. The position limiting portion 420 is inserted into the second mounting opening 220 and abuts against the outer wall surface of the projection 312 and the inner wall surface of the second mounting opening 220, respectively. The connecting portion 410 is used to connect to the projection 312. Referring to Figures 7 to 10, the length to which the position limiting portion 420 is inserted into the second mounting opening 220 is greater than the thickness of the side plate 120. The end of the projection 312 is chamfered in accordance with the connection point between the position limiting portion 420 and the connecting portion 410, and the end face of the projection 312 is flush with the outer wall surface of the side plate 120.
[0086] In one embodiment, the position limiting structure 400 is provided in a substantially L-shape, which is simple in structure and easy to manufacture. The position limiting structure 400 is divided into a position limiting portion 420 inserted into the second mounting opening 220 and a connecting portion 410 fixed relative to the sorting bracket 100. The position limiting structure 400 can be formed by bending a single sheet of metal, making it easy to process. After the position limiting portion 420 is inserted into the second mounting opening 220, it comes into contact with the outer wall surface of the projection 312 and the inner wall surface of the second mounting opening 220, respectively, thereby preventing the shaft rod 310 from moving relative to it in the first direction and limiting its position by contacting the shaft rod 310 in the first direction.
[0087] As considered here, if the length to which the position limiting portion 420 is inserted into the second mounting opening 220 is insufficient, for example, if the length to which the position limiting portion 420 is inserted into the second mounting opening 220 is less than the thickness of the side plate 120, then when the sorting module 10 vibrates or the sorting bracket 100 deforms, the position limiting portion 420 is likely to detach from the second mounting opening 220, and will not be able to perform a position limiting action on the shaft 310 in the first direction, allowing the shaft 310 to move in the first direction. In view of this, in order to solve this problem, the length to which the position limiting portion 420 is inserted into the second mounting opening 220 is set to be greater than the thickness of the side plate 120.
[0088] Referring to Figures 3 and 8, the position limiting structure 400 is formed by bending a sheet metal member to create the position limiting portion 420 and the connecting portion 410. Therefore, the connection point between the connecting portion 410 and the position limiting portion 420 is an arc-shaped transition surface. To avoid interference between the end of the projection 312 corresponding to the connection point between the position limiting portion 420 and the connecting portion 410 and the position limiting structure 400, the end is chamfered, thereby allowing the position limiting structure 400 to be in close contact with the outer surface of the projection 312. Furthermore, if the end face of the projection 312 is provided to protrude from the outer wall surface of the side plate 120, it becomes inconvenient to fix it, requiring a connecting member that matches the shape of the projection, which increases costs. If the end face of the projection 312 is not provided to protrude from the outer wall surface of the side plate 120 and is not flush with the outer wall surface of the side plate 120, there is a risk that the projection 312 will escape from the mounting opening 200 of the side plate 120, affecting the connection between the shaft rod 310 and the sorting bracket 100. In particular, if the side plate 120 deforms outward, the situation in which the projection 312 escapes from the mounting opening 200 of the side plate 120 is more likely to occur. Therefore, the end face of the projection 312 is made flush with the outer wall surface of the side plate 120.
[0089] This application further provides a sorting device comprising a platform assembly and sorting modules. The number of sorting modules is set to multiple, and the multiple sorting modules are arranged in multiple rows and multiple columns on the machine table of the sorting device. Goods are transported by the rotation of roller groups in the sorting modules, and the direction of transport of the goods is controlled by the rotation of the entire sorting module, thereby achieving the purpose of sorting the goods.
