Description

Technical Field

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

[0002] Currently, sorting racks on the market are designed in a simplified and convenient manner, with a general "U" shape. The transmission mechanism usually includes a shaft and gears mounted on the shaft. When installing the transmission mechanism into the sorting rack, the gears are usually mounted on the shaft first, and then the entire shaft is placed into the sorting rack from top to bottom. There are through holes on the side plate of the sorting rack. The two ends of the shaft are aligned with the through holes, and then the shaft is fixedly screwed to the sorting rack by screwing screws.

[0003] However, in this connection method, the diameter of the through hole is usually set to be larger than the diameter of the screw. After the shaft is fixed to the sorting bracket, the position of the screws at both ends of the shaft in the through hole will change. The connection between the shaft and the sorting bracket is unstable, which causes the axis of the shaft to be non-perpendicular to the side plate. This results in the shafts of two adjacent transmission mechanisms not being parallel, causing the gear teeth of the adjacent transmission gears sleeved on the shaft to be misaligned when they mesh. That is, the meshing gears are not on the same plane, resulting in an abnormal meshing situation of "trapezoidal meshing" during meshing, which affects the service life of the gears. Summary of the Invention

[0031] In one embodiment, the sorting module further includes a base, on which the sorting bracket is rotatably mounted, and the base is used to be fixedly connected to the machine base of the sorting device.

[0032] The present invention also proposes a sorting module for a sorting device, the sorting module comprising:

[0033] The sorting support includes a base plate and two side plates disposed on opposite sides of the base plate;

[0034] Mounting ports are respectively provided on the two side plates. The mounting ports include a first mounting port and a second mounting port that are interconnected. The first mounting port extends vertically and the second mounting port extends horizontally.

[0035] A transmission mechanism includes a shaft, a bearing, and a transmission gear. The bearing is sleeved on the shaft, and the transmission gear is sleeved on the bearing. The shaft includes a body portion and a protrusion portion that partially protrudes outward from the middle of both end faces of the body portion. The first mounting port includes an extension port and a square limiting port that communicate with each other. The square limiting port is located below the extension port. The extension port is used for the protrusion portion to be inserted into the square limiting port, and the square limiting port engages and limits the protrusion portion in the horizontal direction. A first stepped surface is formed between the body portion and the protrusion portion, located on the end face of the body portion.

[0061] This invention proposes an embodiment of a sorting module, which is mainly used in a sorting device. The sorting device is a commonly used sorting equipment in existing logistics transportation. It mainly includes a sorting module and a platform assembly. Goods are conveyed by the rotation of the roller assembly on the sorting module, and the overall rotation of the sorting module controls the direction of goods transport, thereby achieving the purpose of sorting the goods. The sorting device typically has multiple sorting modules arranged in an array. The sorting module includes a sorting support and a base. The base is fixedly connected to the frame of the sorting device. The sorting support is mounted on the base and is rotatable relative to the base. A transmission mechanism is installed inside the sorting support and the base. The roller assembly is mounted on the sorting support and is connected to the transmission mechanism, allowing the roller assembly to rotate.

[0062] Please see Figures 1 to 8 In one embodiment of the present invention, the sorting module 10 is used for a sorting device. The sorting module 10 includes a sorting bracket 100, a mounting port 200, a transmission mechanism 300, and a limiting structure 400. The sorting bracket 100 includes a base plate 110 and two side plates 120 disposed on opposite sides of the base plate 110. The mounting ports 200 are respectively disposed on the two side plates 120, and the mounting ports 200 include a first mounting port 210 and a second mounting port 220 that are interconnected. The transmission mechanism 300 includes a shaft 310 mounted on the first mounting port 210, and the shaft 310 is fixed relative to the first mounting port 210. The first mounting port 210 has a first direction for inserting the shaft 310, and the shaft 310 abuts against and limits the opposite side walls of the first mounting port 210 in a second direction. The limiting structure 400 is disposed in the second mounting port 220 to abut and limit the shaft 310 in the first direction. The first direction and the second direction intersect.

[0063] Specifically, please refer to Figure 4 The sorting bracket 100 includes a base plate 110 and two side plates 120 disposed on opposite sides of the base plate 110. An installation space is 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 can be fixed together by screws 500 or by other means. For ease of production, the sorting bracket 100 of this invention is integrally formed from sheet metal, resulting in a simple structure and convenient processing. This further improves the production efficiency of the sorting bracket 100 and reduces production costs. Furthermore, after the sorting bracket 100 is manufactured, no secondary processing is required, simplifying the production process and improving efficiency. The material cost of the sheet metal-made sorting bracket 100 is relatively low, further reducing costs.

[0064] Please see 4 and Figure 5 On each of the two side plates 120, a first mounting opening 210 and a second mounting opening 220 are correspondingly provided and communicate with each other. The shape of the first mounting opening 210 and / or the second mounting opening 220 can be a long strip, an arc, an opening with a bend, or an opening of other shapes, without specific limitations. For ease of processing and manufacturing, the shape of the opening is usually set to a regular edge, such as a square or a circle. In this embodiment, both the first mounting opening 210 and the second mounting opening 220 are long strips.

[0065] Please see Figure 2 and Figure 7 The two ends of the shaft 310 are respectively installed in the first mounting openings 210 of the two side plates 120, and the shaft 310 is fixed relative to the first mounting openings 210 and will not rotate. During the process of inserting the shaft 310 into the first mounting opening 210, the direction in which the shaft 310 is inserted is limited to a first direction. After the shaft 310 is installed into the first mounting opening 210, at least part of the outer surface of the shaft 310 abuts against the two opposite side walls of the first mounting opening 210, so that the shaft 310 installed in the first mounting opening 210 is limited in a second direction.

[0066] Meanwhile, a limiting structure 400 is provided in the second mounting port 220. This limiting structure 400 abuts against the shaft 310, thereby limiting the shaft 310 in the first direction. Thus, through the cooperation between the shaft 310 and the two opposite side walls of the first mounting port 210, and the limiting effect of the limiting structure 400, the position of the shaft 310 installed in the mounting port 200 can be restricted, preventing movement of the shaft 310. This ensures that the shaft 310 is installed in the preset position without deviation, guaranteeing 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 for meshing, they mesh on the same plane, preventing abnormal meshing conditions such as misaligned teeth or point meshing between gears, thus ensuring the service life of the gears.

[0067] It should be noted that the first direction intersects with the second direction. The first direction can be horizontal, vertical, or inclined, and there are no specific restrictions on it.

[0068] The technical solution of the present invention fixes the position of the shaft 310 installed in the first mounting port 210 by limiting it in the intersecting first and second directions through the two opposing side walls of the first mounting port 210 and the limiting structure 400. This prevents the shaft 310 from shifting relative to the sorting bracket 100, ensuring the stability of the connection between the shaft 310 and the sorting bracket 100. Furthermore, it avoids the abnormal meshing situation of "trapezoidal meshing" that occurs when the transmission gears 320 installed on two adjacent shafts 310 are meshed, where the gear teeth are not aligned, i.e., the meshing gears are not on the same plane. This ensures the service life of the gears.

[0069] Please see Figure 2 , Figure 3 , Figures 7 to 10 In one embodiment, the shaft 310 includes a body portion 311 and protrusions 312 protruding outward from both ends of the body portion 311. A first stepped surface 313 located on the end face of the body portion 311 is formed between the body portion 311 and the protrusions 312. The protrusions 312 are disposed in the first mounting opening 210, and the first stepped surface 313 abuts against the inner wall surface of the side plate 120.

[0070] Specifically, please refer to Figure 10 The shaft 310 includes a rod-shaped body portion 311 and protrusions 312 extending outward from both ends of the body portion 311 along its length. It should be noted that the protrusions 312 are formed by a partial outward protrusion from the center of the end face of the body portion 311, and the midpoint of the protrusion 312 coincides with the axis of the body portion 311. Since the protrusions 312 are formed by a partial outward protrusion from the center of the end face of the body portion 311, a first stepped surface 313 exists between the body portion 311 and the protrusions 312. The first stepped surface 313 is the end face of the body portion 311 when the protrusions 312 are not protruding. The shape of the protrusions 312 can be set to a more regular shape to better limit their movement through the opposing side walls of the first mounting opening 210.

[0071] In the radial direction of the shaft 310, the cross-section of the protrusion 312 is square. The square is approximately a perfect square, and for ease of processing and safety considerations, all four sides of the square are chamfered. Of course, in other embodiments, the cross-section of the protrusion 312 can also be circular, triangular, trapezoidal, or other shapes; no specific limitation is imposed.

[0072] Please see Figure 7 and Figure 8The first stepped surface 313 abuts against the inner wall surface of the side plate 120. This arrangement limits the axial direction of the shaft 310. Simultaneously, it prevents deformation of the sorting bracket 100 (i.e., inward deformation of the two side plates 120 of the sorting bracket 100) caused by excessive tightening of the screws 500 when connecting the shaft 310 to the sorting bracket 100. This would prevent misalignment of the gear teeth when multiple transmission shafts mesh, meaning the meshing gears would not be on the same plane, resulting in a "trapezoidal meshing" situation, thus ensuring the service life of the gears.

[0073] It is worth mentioning that the end face of the protrusion 312 is flush with the outer wall surface of the side plate 120. Specifically, if the end face of the protrusion 312 is made to protrude from the outer wall surface of the side plate 120, it is inconvenient to fix it, requiring a connector adapted to the shape of the protrusion, which increases costs. On the other hand, if the end face of the protrusion 312 is not made 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, the protrusion 312 may detach from the mounting opening 200 of the side plate 120, affecting the connection between the shaft 310 and the sorting bracket 100, especially when the side plate 120 deforms outward, the protrusion 312 is more likely to detach from the mounting opening 200 of the side plate 120. Therefore, the end face of the protrusion 312 is optionally flush with the outer wall surface of the side plate 120.

[0074] Please see Figure 4 and Figure 5 In one embodiment, the first mounting port 210 includes an extension port 211 and a limiting port 212 that are interconnected. The extension port 211 is used for the protrusion 312 to be inserted into the limiting port 212, and the second mounting port 220 penetrates the opposite side walls of the extension port 211.

[0075] Specifically, when installing the shaft 310, first, both ends of the shaft are inserted into the insertion port 211 respectively. Then, the protrusion 312 is moved from the insertion port 211 to the limiting port 212 to limit the shaft 310 in the first direction. The second mounting port 220 penetrates the two opposite side walls of the insertion port 211. Placing the limiting structure 400 in the second mounting port 220 can limit the shaft 310 in the second direction.

[0076] Please see Figure 4 and Figure 5 In one embodiment, in the first direction, the height of the insertion port 211 is greater than the height of the limiting port 212. This arrangement allows both ends of the shaft 310 to easily extend into the insertion port 211, and provides sufficient space for the protrusion 312 to move to the limiting port 212 for limiting.

[0077] Please see Figure 4 and Figure 5 In one embodiment, the distance between the two side walls of the inlet 211 is greater than the diameter of the shaft 310 in a direction perpendicular to the first direction. Specifically, by setting the distance between the two side walls of the inlet 211 to be greater than the diameter of the shaft 310, the shaft 310 can pass through the inlet 211. When installing the shaft 310, one end of the shaft 310 can be passed through the inlet 211, and then the other end can be moved downwards into the inlet 211 on the other side plate 120. Then, the protrusion 312 is moved from the inlet 211 to the limiting port 212 for limiting, making installation convenient and quick.

[0078] Please see Figure 4 and Figure 5 In one embodiment, in the axial direction of the shaft 310, the cross-sectional area of ​​the inlet 211 is 1-3 times the cross-sectional area of ​​the limiting opening 212. Specifically, setting the cross-sectional area of ​​the inlet 211 in the axial direction of the shaft 310 to 1-3 times the cross-sectional area of ​​the limiting opening 212 ensures that the cross-sectional area of ​​the inlet 211 is sufficiently large compared to the cross-sectional area of ​​the limiting opening 212, facilitating the installation of the shaft 310 into the mounting opening 200.

[0079] Please continue reading. Figure 4 and Figure 5 In one embodiment, in the first direction, the height of the second mounting opening 220 is less than the height of the limiting opening 212. Specifically, the second mounting opening 220 is mainly used for mounting the limiting structure 400 to limit the shaft 310 in the first direction. The limiting principle of the limiting structure 400 is that its two opposing surfaces abut against the protrusion 312 installed in the limiting opening 212 and the inner wall surface of the second mounting opening 220, so that the protrusion 312 will not be displaced in the first direction, thereby limiting the shaft 310 in the first direction. Setting the height of the second mounting opening 220 to be less than the height of the limiting opening 212 has two advantages: firstly, a limiting structure 400 with a low height (i.e., a thinner thickness) can be used to limit the shaft 310, and the requirements for the limiting structure 400 are not high; secondly, it ensures that a sufficient portion of the protrusion 312 is located in the limiting opening 212, ensuring the limiting effect of the two opposing sidewalls of the limiting opening 212 on the protrusion 312 in the second direction.

[0080] Please see Figure 4 and Figure 5In one embodiment, the second mounting opening 220 extends along a second direction, and in this second direction, the length of the second mounting opening 220 is greater than the width of the insertion opening 211 and the limiting opening 212. Specifically, the second mounting opening 220 can extend along the second direction, and in this second direction, the second mounting opening 220 penetrates the sidewall of the insertion opening 211, ensuring that the length of the second mounting opening 220 is long enough so that the limiting structure 400 installed in the second mounting opening 220 can completely cover the protrusion 312 installed in the limiting opening 212, thereby limiting the shaft 310 in the first direction.

[0081] Please see Figure 5 , Figures 7 to 10 In one embodiment, a second stepped surface 314 is further formed between the body portion 311 and the protrusion portion 312. The first mounting port 210 has a bottom wall 212a downstream in the first direction. The second stepped surface 314 is located on the side of the protrusion portion 312 away from the bottom wall 212a. The maximum distance from the second stepped surface 314 to the end face of the protrusion portion 312 is greater than the maximum distance from the first stepped surface 313 to the end face of the protrusion portion 312.

[0082] Specifically, the main body 311 of the shaft 310 is a rod-shaped cylinder. The protrusions 312, extending outward from both ends, are roughly cuboid in shape, thus forming a stepped surface between the protrusions 312 and the main body 311. These stepped surfaces can be roughly divided into four stepped surfaces corresponding to the four sides of the protrusions 312. These four stepped surfaces can be connected end-to-end to form a ring-shaped stepped surface, or they can be separated to form four independent stepped surfaces, or two or three adjacent stepped surfaces can be connected end-to-end; no specific limitation is made. 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 of the side plate 120, mainly serving to limit the axial movement of the shaft 310. The maximum distance from the second step surface 314 to the end face of the protrusion 312 is greater than the maximum distance from the first step surface 313 to the end face of the protrusion 312. In other words, the second step surface 314 is sufficiently deep in the axial direction of the shaft 310, and the second step surface 314 is located on the side of the protrusion 312 away from the bottom wall 212a. That is, in the axial direction of the shaft 310, the projection of the second step surface 314 at least partially coincides with the second mounting opening 220. This allows the limiting structure 400 installed in the second mounting opening 220 to extend to a sufficiently deep length, at least greater than the length of the protrusion 312, to ensure the limiting effect of the limiting structure 400 on the shaft 310 in the first direction.

[0083] Please see Figure 2 and Figure 3In one embodiment, the limiting structure 400 includes a connecting portion 410 and a limiting portion 420 connected to one end of the connecting portion 410. The limiting portion 420 extends into the second mounting opening 220 and abuts against the outer wall surface of the protrusion 312 and the inner wall surface of the second mounting opening 220, respectively. The connecting portion 410 is used to connect with the protrusion 312. Specifically, the limiting structure 400 is generally L-shaped, with a simple structure and easy manufacturing. The limiting structure 400 is divided into a limiting portion 420 inserted into the second mounting opening 220 and a connecting portion 410 used to fix relative to the sorting bracket 100. The limiting structure 400 can be formed by bending a single sheet metal part, making processing convenient. After the limiting part 420 is inserted into the second mounting port 220, it abuts against the outer wall surface of the protrusion 312 and the inner wall surface of the second mounting port 220 respectively, so that the shaft 310 will not move relative to each other in the first direction, and the shaft 310 is abutted and limited in the first direction.

[0084] Please see Figure 2 , Figure 3 , Figure 8 and Figure 10 In one embodiment, the outer end face of the protrusion 312 is provided with a screw hole 312a, and the connecting part 410 is provided with a through hole 411 for the screw 500 to pass through. The screw 500 passes through the through hole 411 and is screwed into the screw hole 312a. Specifically, a through hole 411 can be directly provided on the connecting part 410 so that the screw 500 passes through and is screwed into the screw hole 312a on the protrusion 312 of the shaft 310 to fix the position of the limiting structure 400. The connection method is simple, and the screw 500 fixes the limiting structure 400, the sorting bracket 100, and the shaft 310 relatively, which can further ensure that the shaft 310 will not be displaced in the mounting port 200. Of course, in other embodiments, a hole can be made on the sorting bracket 100 to fix the limiting structure 400, so that the limiting structure 400 is fixed relative to the sorting bracket 100, ensuring the limiting effect of the limiting structure 400 on the shaft 310. Alternatively, other connection methods can be used to fix the limiting structure 400, and no specific restrictions are imposed on this.

[0085] Please see Figure 8Considering that if the length of the limiting part 420 extending into the second mounting port 220 is insufficient—for example, if the length of the limiting part 420 extending into the second mounting port 220 is less than the thickness of the side plate 120—the limiting part 420 may easily detach from the second mounting port 220 when the sorting module 10 is vibrated or the sorting bracket 100 is deformed, thus failing to limit the shaft 310 in the first direction, and the shaft 310 can move in the first direction. Therefore, to solve this problem, the length of the limiting part 420 extending into the second mounting port 220 can be set to be greater than the thickness of the side plate 120.

[0086] Please see Figure 3 , Figure 8 and Figure 10 It should be noted that the end of the protrusion 312 is chamfered at the connection between the limiting part 420 and the connecting part 410. Specifically, the limiting structure 400 is formed by bending a sheet metal part to create the limiting part 420 and the connecting part 410; therefore, the connection between the connecting part 410 and the limiting part 420 is an arc-shaped transition surface. To avoid interference between the end of the protrusion 312 at the connection between the limiting part 420 and the connecting part 410 and the limiting structure 400, it is chamfered so that the limiting structure 400 can fit snugly against the outer surface of the protrusion 312.

[0087] In one embodiment, the angle formed by the first direction and the second direction is in the range of 45°-135°. Specifically, the angle between the first direction and the second direction can be set within the range of 45°-135°. Within this range, it can be ensured that the shaft 310 installed in the first mounting port 210 can be limited in both the first and second directions. In this embodiment, the first direction is the extension direction of the first mounting port 210, and the second mounting port 220 is the extension direction of the second mounting port 220.

[0088] Furthermore, the first direction is perpendicular to the second direction. That is, the extension direction of the first mounting port 210 is perpendicular to the extension direction of the second mounting port 220. The vertically arranged first mounting port 210 and second mounting port 220 are easy to process, and the limiting structure 400 installed in the second mounting port 220 can better cooperate with the protrusion 312 installed in the first mounting port 210 to limit the shaft 310 in the first direction.

[0089] Furthermore, the first mounting opening 210 extends vertically, and the second mounting opening 220 extends horizontally. The vertically and horizontally extending first mounting opening 210 and second mounting opening 220 facilitate processing, and the shaft 310 installed in the first mounting opening 210 can be secured by the limiting opening 212 at the bottom of the first mounting opening 210. Simultaneously, the vertically extending first mounting opening 210 also facilitates the insertion of the shaft 310 into the first mounting opening 210 for installation.

[0090] Please see Figure 1 , Figure 6 and Figure 9 In one embodiment, the transmission mechanism 300 further includes a transmission gear 320, and the sorting module 10 further includes a roller assembly 600. The transmission gear 320 is rotatably mounted on the shaft 310, and the roller assembly 600 is mounted on the sorting bracket 100. The roller assembly 600 has a roller gear 610, and the transmission gear 320 meshes with the roller gear 610.

[0091] Specifically, the transmission gear 320 is rotatably mounted on the shaft 310. A corresponding mounting position can be provided on the sorting bracket 100 for the roller assembly 600 to be installed. The roller gear 610 of the roller assembly 600 meshes with the transmission gear 320. When the transmission gear 320 rotates, it drives the roller gear 610 to rotate, thereby allowing the roller assembly 600 to rotate and convey goods passing through it. The transmission gear 320 is located at one end of the shaft 310. A blocking step and an annular groove 315 can be provided on the shaft 310. The blocking step limits one side of the transmission gear 320, and a retaining ring is provided in the annular groove 315 to limit the other side of the transmission gear 320.

[0092] Please see Figure 6 , Figure 7 and Figure 9 In one embodiment, the transmission mechanism 300 further includes a bearing 330, which includes an inner bearing ring, an outer bearing ring, and a bearing ball located between the inner bearing ring and the outer bearing ring; the inner bearing ring is fitted onto the shaft 310 and fixed relative to the shaft 310, and the outer bearing ring is connected to the transmission gear 320.

[0093] Specifically, the inner ring of the bearing is sleeved on the shaft 310 and fixed relative to the shaft 310. The transmission gear 320 is sleeved on the outer ring of the bearing and fixed relative to it. A drive mechanism 800 can be provided on one side of the transmission mechanism 300, which provides power to the transmission mechanism 300. The transmission gear 320 meshes with the drive gear 810 of the drive mechanism 800. When the drive gear 810 rotates, it drives the transmission gear 320 to rotate, thereby driving the roller gear 610 to rotate. The roller assembly 600 rotates, conveying the goods passing through the roller assembly 600.

[0094] Please see Figure 1 In one embodiment, the sorting module 10 further includes a base 700, and the sorting bracket 100 is rotatably mounted on the base 700. The base 700 is used to fix the sorting device to the machine base. Specifically, the sorting module 10 is fixedly mounted on the machine base of the sorting device via the base 700, and the sorting bracket 100 is rotatable relative to the base 700. The roller assembly 600 is mounted on the sorting bracket 100 and fixed relative to the sorting bracket 100. When the sorting bracket 100 rotates, it can drive the roller assembly 600 to rotate, thereby controlling the transport direction of goods passing through the roller assembly 600. Typically, the sorting device includes multiple sorting modules 10, which are arranged in multiple rows and columns. A connection hole is provided on the base plate 110 of the sorting bracket 100 for connecting rods. A row or column of sorting racks 100 can be connected by a connecting rod, allowing the entire row of sorting racks 100 to rotate as the connecting rod moves. This connection method only requires a single motor to drive the connecting rod, reducing the number of motors needed and thus significantly lowering costs. Furthermore, this connection method is simple to operate, easy to install, and improves production efficiency.

[0095] Please see Figures 1 to 10The present invention also proposes a sorting module 10. In one embodiment of the present invention, the sorting module 10 is used for a sorting device. The sorting module 10 includes a sorting bracket 100, a mounting port 200, a transmission mechanism 300, a limiting structure 400, and a roller group 600. The sorting bracket 100 includes a base plate 110 and two side plates 120 disposed on opposite sides of the base plate 110; mounting openings 200 are respectively disposed on the two side plates 120, and each mounting opening 200 includes a first mounting opening 210 and a second mounting opening 220 that are interconnected, the first mounting opening 210 extending vertically and the second mounting opening 220 extending horizontally; the transmission mechanism 300 includes a shaft 310, a bearing 330 and a transmission gear 320, the bearing 330 being sleeved on the shaft 310 and the transmission gear 320 being sleeved on the bearing 330; the shaft 310 includes a body portion 311 and a protrusion portion 312 formed by partially protruding outward from the middle of the two end faces of the body portion 311; the first mounting opening 210 includes an extension port that is interconnected. 211 and a square limiting opening 212, the square limiting opening 212 being located below the extension opening 211, the extension opening 211 being used for the protrusion 312 to be inserted into the square limiting opening 212, the square limiting opening 212 engaging and limiting the protrusion 312 in the horizontal direction; a first stepped surface 313 is formed between the body part 311 and the protrusion 312, located on the end face of the body part 311, the first stepped surface 313 abutting against the inner wall surface of the side plate 120; the limiting structure 400 is disposed at the second mounting opening 220, used to abut and limit the shaft 310 in the vertical direction; the roller assembly 600 is disposed on the sorting bracket 100, the roller assembly 600 having a roller gear 610, the transmission gear 320 meshing with the roller gear 610.

[0096] Specifically, please refer to Figure 4 The sorting bracket 100 includes a base plate 110 and two side plates 120 disposed on opposite sides of the base plate 110. An installation space is 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 can be fixed together by screws 500 or by other means. For ease of production, the sorting bracket 100 of this invention is integrally formed from sheet metal, resulting in a simple structure and convenient processing. This further improves the production efficiency of the sorting bracket 100 and reduces production costs. Furthermore, after the sorting bracket 100 is manufactured, no secondary processing is required, simplifying the production process and improving efficiency. The material cost of the sheet metal-made sorting bracket 100 is relatively low, further reducing costs.

[0097] Please see Figure 5 On each of the two side plates 120, a first mounting opening 210 and a second mounting opening 220 are correspondingly provided and communicate with each other. The shape of the first mounting opening 210 and / or the second mounting opening 220 can be a long strip, an arc, a bend, or other shapes, without specific limitations. For ease of manufacturing, the shape of the opening is usually set to a regular edge, such as a square or a circle. In this embodiment, both the first mounting opening 210 and the second mounting opening 220 are long strips. Further, the first mounting opening 210 extends vertically, and the second mounting opening 220 extends horizontally. The first mounting opening 210 and the second mounting opening 220 extending vertically and horizontally facilitate manufacturing, and the shaft 310 installed in the first mounting opening 210 can be locked and limited by the limiting opening 212 at the bottom of the first mounting opening 210. Meanwhile, the first mounting port 210, which extends vertically, also facilitates the insertion of the shaft 310 into the first mounting port 210 for installation.

[0098] Please see 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 mounted on the shaft 310. A corresponding mounting position can be provided on the sorting bracket 100 for the roller assembly 600 to be installed. The roller gear 610 of the roller assembly 600 meshes with the transmission gear 320. When the transmission gear 320 rotates, it drives the roller gear 610 to rotate, thereby allowing the roller assembly 600 to rotate and convey goods passing through it. The bearing 330 includes an inner bearing ring, an outer bearing ring, and bearing balls located between the inner and outer bearing rings. The inner bearing ring is mounted on the shaft 310 and fixed relative to it. The transmission gear 320 is mounted on the outer bearing ring and fixed relative to it. A drive mechanism 800 can be provided on one side of the transmission mechanism 300, providing power to the transmission mechanism 300. The transmission gear 320 meshes with the drive gear 810 of the drive mechanism 800. When the drive gear 810 rotates, it drives the transmission gear 320 to rotate, which in turn drives the roller gear 610 to rotate. The roller assembly 600 rotates on its own to transport goods passing through the roller assembly 600.

[0099] Please see Figure 10The shaft 310 includes a rod-shaped body portion 311 and protrusions 312 extending outward from both ends of the body portion 311 along its length. It should be noted that the protrusions 312 are formed by a partial outward protrusion from the center of the end face of the body portion 311, and the midpoint of the protrusion 312 coincides with the axis of the body portion 311. Since the protrusions 312 are formed by a partial outward protrusion from the center of the end face of the body portion 311, a first stepped surface 313 exists between the body portion 311 and the protrusions 312. This first stepped surface 313 is the end face of the body portion 311 when the protrusions 312 are not protruding. The protrusion 312 is placed into the square limiting port 212. The protrusion 312 and the two side walls opposite to the directional limiting port 212 cooperate to limit the shaft 310 in the horizontal direction. The shaft 310 installed in the first mounting port 210 is fixed relative to the first mounting port 210 and will not rotate on its own.

[0100] Please see Figure 7 and Figure 8 The first stepped surface 313 abuts against the inner wall surface of the side plate 120. This arrangement limits the axial direction of the shaft 310. Simultaneously, it prevents deformation of the sorting bracket 100 (i.e., inward deformation of the two side plates 120 of the sorting bracket 100) caused by excessive tightening of the screws 500 when connecting the shaft 310 to the sorting bracket 100. This would prevent misalignment of the gear teeth when multiple transmission shafts mesh, meaning the meshing gears would not be on the same plane, resulting in a "trapezoidal meshing" situation, thus ensuring the service life of the gears.

[0101] Please see Figure 2 and Figure 3 Meanwhile, a limiting structure 400 is provided in the second mounting port 220. This limiting structure 400 abuts against the shaft 310, thereby limiting the shaft 310 in the vertical direction. Thus, through the cooperation between the shaft 310 and the two opposite side walls of the first mounting port 210, and the limiting effect of the limiting structure 400, the position of the shaft 310 installed in the mounting port 200 can be restricted, preventing movement of the shaft 310. This ensures that the shaft 310 is installed in the preset position without deviation, guaranteeing 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 for meshing, they mesh on the same plane, preventing abnormal meshing conditions such as misaligned teeth or point meshing between gears, thus ensuring the service life of the gears.

[0102] Please see Figures 2 to 5 , Figure 8In one embodiment, the second mounting port 220 penetrates the opposite side walls of the extension port 211. In the vertical direction, the height of the extension port 211 is greater than the height of the square limiting port 212, and the height of the second mounting port 220 is less than the height of the square limiting port 212. In the horizontal direction, the distance between the two side walls of the extension port 211 is greater than the diameter of the shaft 310.

[0103] Specifically, please refer to Figure 5 The second mounting port 220 penetrates the two opposite side walls of the extension port 211. Placing the limiting structure 400 in the second mounting port 220 allows for limiting the shaft 310 in the second direction. In the vertical direction, the height of the extension port 211 is set greater than the height of the square limiting port 212, while the height of the second mounting port 220 is less than the height of the square limiting port 212. This arrangement allows both ends of the shaft 310 to easily extend into the extension port 211, providing sufficient space for the protrusion 312 to move to the limiting port 212 for limiting. Furthermore, the shaft 310 can pass through the extension port 211. During installation, one end of the shaft 310 can be passed through the extension port 211, and the other end moved downwards to the extension port 211 on the other side plate 120. Then, the protrusion 312 is moved from the extension port 211 to the limiting port 212 for limiting, making installation convenient and quick.

[0104] Please see Figures 8 to 10 In one embodiment, a second stepped surface 314 is formed between the body portion 311 and the protrusion portion 312. The second stepped surface 314 is located on the side of the protrusion portion 312 away from the bottom of the first mounting opening 210. The maximum distance from the second stepped surface 314 to the end face of the protrusion portion 312 is greater than the maximum distance from the first stepped surface 313 to the end face of the protrusion portion 312.

[0105] Specifically, the main body 311 of the shaft 310 is a rod-shaped cylinder, and the protrusions 312 extending outward from both ends are roughly cuboid, thus forming a stepped surface between the protrusions 312 and the main body 311. These stepped surfaces can be roughly divided into four stepped surfaces corresponding to the four sides of the protrusions 312. These four stepped surfaces can be connected end-to-end to form a ring-shaped stepped surface, or they can be separated to form four independent stepped surfaces, or two or three adjacent stepped surfaces can be connected end-to-end; no specific limitation is made in this regard. 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, mainly serving to limit the axial movement of the shaft 310. The maximum distance from the second step surface 314 to the end face of the protrusion 312 is greater than the maximum distance from the first step surface 313 to the end face of the protrusion 312. In other words, the second step surface 314 is sufficiently deep in the axial direction of the shaft 310, and the second step surface 314 is located on the side of the protrusion 312 away from the bottom wall 212a. That is, in the axial direction of the shaft 310, the projection of the second step surface 314 at least partially coincides with the second mounting opening 220. This allows the limiting structure 400 installed in the second mounting opening 220 to extend to a sufficiently deep length, at least greater than the length of the protrusion 312, to ensure the limiting effect of the limiting structure 400 on the shaft 310 in the vertical direction.

[0106] Please see Figures 1 to 3 In one embodiment, the limiting structure 400 includes a connecting portion 410 and a limiting portion 420 connected to one end of the connecting portion 410. The limiting portion 420 extends into the second mounting opening 220 and abuts against the outer wall surface of the protrusion 312 and the inner wall surface of the second mounting opening 220, respectively. The connecting portion 410 is used to connect with the protrusion 312. Please refer to [link to previous document]. Figures 7 to 10 The length of the limiting part 420 extending into the second mounting port 220 is greater than the thickness of the side plate 120; the end of the protrusion 312 is chamfered at the connection between the limiting part 420 and the connecting part 410, and the end face of the protrusion 312 is flush with the outer wall surface of the side plate 120.

[0107] Specifically, the limiting structure 400 is roughly L-shaped, simple in structure, and easy to manufacture. The limiting structure 400 consists of a limiting part 420 that inserts into the second mounting port 220, and a connecting part 410 for relative fixation with the sorting bracket 100. The limiting structure 400 can be formed by bending a single sheet metal piece, making processing convenient. After the limiting part 420 is inserted into the second mounting port 220, it abuts against the outer wall surface of the protrusion 312 and the inner wall surface of the second mounting port 220, respectively, so that the shaft 310 will not move relative to the first direction, thus limiting the shaft 310 in the first direction.

[0108] Considering that if the length of the limiting part 420 extending into the second mounting port 220 is insufficient—for example, if the length of the limiting part 420 extending into the second mounting port 220 is less than the thickness of the side plate 120—the limiting part 420 may easily detach from the second mounting port 220 when the sorting module 10 is vibrated or the sorting bracket 100 is deformed, thus failing to limit the shaft 310 in the first direction, allowing the shaft 310 to move in the first direction. Therefore, to solve this problem, the length of the limiting part 420 extending into the second mounting port 220 can be set to be greater than the thickness of the side plate 120.

[0109] Please see Figure 3 and Figure 8 The limiting structure 400 is formed by bending a sheet metal part to create the limiting portion 420 and the connecting portion 410. Therefore, the connection between the connecting portion 410 and the limiting portion 420 is an arc-shaped transition surface. To prevent the end of the protrusion 312 corresponding to the connection between the limiting portion 420 and the connecting portion 410 from interfering with the limiting structure 400, it is chamfered so that the limiting structure 400 can fit snugly against the outer surface of the protrusion 312. Meanwhile, if the end face of the protrusion 312 is made to protrude beyond the outer wall surface of the side plate 120, it is inconvenient to fix it, requiring a connector adapted to the shape of the protrusion, which increases costs. Conversely, if the end face of the protrusion 312 is not made to protrude beyond the outer wall surface of the side plate 120 and is not flush with it, the protrusion 312 may detach from the mounting opening 200 of the side plate 120, affecting the connection between the shaft 310 and the sorting bracket 100, especially when the side plate 120 deforms outwards, making it more likely for the protrusion 312 to detach from the mounting opening 200. Therefore, optionally, the end face of the protrusion 312 can be flush with the outer wall surface of the side plate 120.

[0110] This invention also proposes a sorting device, which includes a platform component and sorting modules. Multiple sorting modules are arranged in multiple rows and columns on the machine platform of the sorting device. Goods are conveyed by the rotation of roller groups on the sorting modules, and the conveying direction of the goods is controlled by the overall rotation of the sorting modules, thereby achieving the purpose of sorting the goods. The specific structure of the sorting modules is as described in the above embodiments. Since this sorting device adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here.

[0111] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
