Description

Technical Field

[0001] The utility model relates to the technical field of express delivery sorting, and in particular to a sorting and transportation system. Background Art

[0002] A sorting unit is a type of logistics sorting equipment. Its execution device is the sorting platform. To improve its sorting efficiency, its inherent performance must be ensured. This performance includes structural compactness, service life, layout rationality, maintenance frequency, and sorting accuracy.

[0003] At present, the sorting platform is often configured to be electrically driven, which includes a motor, two rollers, and a belt for linking the two rollers. The motor drives one roller to operate. Since the sorting unit needs to operate for a long time, the motor will be easily damaged after a long period of operation, making it difficult to reduce the maintenance frequency of the sorting platform and reducing the express sorting efficiency. Even if the operation of the sorting platform is controlled by a mechanical structure in conjunction with a clutch device, the clutch device is often configured to be exposed. The exposed clutch device will also occupy a part of the space outside the frame of the sorting unit, which will affect the upper package platform and the lower package grid, limit the rationality of the layout of the sorting unit, reduce the performance of the sorting unit, and thus reduce the performance of the sorting and transportation system.

[0004] The form of using a mechanical structure to cooperate with a clutch device to operate the sorting platform is to utilize the operating action of the sorting unit to drive the sorting platform to operate through the mechanical structure. The torque input end of the mechanical structure is the first driving wheel. Since the sorting platform of the sorting unit only needs to operate in specific parts of the sorting and transportation line, such as the upper and lower bag parts, the first driving wheel serves as the supporting wheel of the sorting unit and needs to be supported on the sorting and transportation line at all times. Therefore, when the sorting platform has no operating requirements, the first driving wheel will have unnecessary wear, which reduces the service life of the first driving wheel and makes it easier for the first driving wheel to slip on the sorting and transportation line, which is not conducive to improving the operating accuracy of the sorting platform, reduces the service life of the sorting unit, increases the maintenance frequency of the sorting unit, and also reduces the performance of the sorting unit, thereby reducing the performance of the sorting and transportation system.

[0033] (3) Beneficial effects

[0034] The beneficial effect of the present invention is as follows: in the sorting and transportation system of the present invention, the first sorting platform is driven to operate by the first rotating shaft. When the first sorting platform has an operation demand, it is the operation range of the first sorting platform; when the first sorting platform does not have an operation demand, it is the stagnation range of the first sorting platform. Only in the operation range of the first sorting platform does the first driving wheel maintain contact with the friction section, and in the stagnation range of the first sorting platform, the first driving wheel is separated from the friction section and remains suspended, so as to avoid unnecessary wear of the first driving wheel, thereby reducing the maintenance frequency of the sorting unit and improving the sorting accuracy of the sorting unit.

[0035] A first assembly cavity is formed between the frame and the first sorting platform, and the first assembly cavity can effectively protect the first clutch device without affecting the normal operation of the first clutch device;

[0036] Due to the provision of the first assembly cavity, the first clutch device can be embedded in the outline of the frame, so the first clutch device will not affect the height layout of the frame.

[0037] At the same time, one side opening of the first assembly cavity is shielded by the first sorting platform. The first sorting platform itself has a requirement for its own extension length along the width direction of the sorting unit. Therefore, even if the provision of the first assembly cavity and the first clutch device causes the size of the frame along the width direction of the sorting unit to increase, it will not protrude beyond the vertical projection outline of the first sorting platform. Therefore, the first clutch device will not affect the overall layout of the sorting unit.

[0038] Since the first assembly cavity is entirely embedded in the outline of the frame, the sorting unit is cleverly used as a component of the first assembly cavity, so that after the first clutch device is assembled, it will not occupy space outward in the width direction of the sorting unit, nor will it occupy space in the height direction of the sorting unit, and will not occupy space in the length direction of the sorting unit. Therefore, the sorting unit will not appear bloated, which is conducive to improving the structural compactness and aesthetics of the sorting unit, and will not affect the upper packaging platform and lower packaging grid of the sorting unit, thereby not reducing the utilization rate of the site where the sorting unit is located, thereby improving the rationality of the sorting unit layout, further improving the overall performance of the sorting unit, and thus improving the performance of the sorting and transportation system.

[0039] This sorting and transportation system improves existing sorting unit issues in terms of sorting efficiency, sorting accuracy, maintenance frequency, and layout rationality, effectively ensuring the performance of the sorting unit and, ultimately, the sorting and transportation system. As the performance of the sorting and transportation system improves, the cost of express delivery sorting will also decrease, thus facilitating the development and promotion of automated express delivery sorting and providing a partial hardware foundation for the realization of unmanned express delivery sorting stations.

DETAILED DESCRIPTION

[0057] In order to better explain the present invention, and to facilitate understanding, the following Figure 1-15 , through the specific implementation method, the utility model is described in detail. Among them, the directional nouns such as "upper" and "lower" mentioned in this article are Figure 1 The orientation is referenced.

[0058] Example 1:

[0059] Reference Figures 1-10 , an embodiment of the present utility model provides a sorting and transportation system, including a sorting unit I and a sorting and transportation line II, wherein a plurality of sorting units I are connected end to end and run along the sorting and transportation line II; the sorting unit I includes a frame 1 and a first sorting platform 3; the sorting unit I also includes a first clutch device 2, a first driving wheel 5 and a first rotating shaft 4; a first assembly cavity A with an open lower side is formed between the frame 1 and the first sorting platform 3, and the first clutch device 2 is arranged in the first assembly cavity A so that the first clutch device 2 is embedded in the outline of the frame 1; the sorting and transportation line II includes a friction section 201, and when the sorting unit I runs along the sorting and transportation line II, it can switch the first sorting platform 3 between an operating section and a stagnant section; in the operating section of the first sorting platform 3, the first driving wheel 5 maintains friction contact with the friction section 201 to enable the first driving wheel 5 to operate; in the stagnant section of the first sorting platform 3, the first driving wheel 5 remains separated from the friction section 201 so that the first driving wheel 5 is suspended.

[0060] In this embodiment, the first sorting platform 3 is driven by the first rotating shaft 4. When the first sorting platform 3 is in operation, it is in the operation range of the first sorting platform 3; when the first sorting platform 3 is not in operation, it is in the stagnation range of the first sorting platform 3. Only in the operation range of the first sorting platform 3 does the first driving wheel 5 maintain contact with the friction segment 201. In the stagnation range of the first sorting platform 3, the first driving wheel 5 is disengaged from the friction segment 201 and remains suspended, thereby avoiding unnecessary wear of the first driving wheel 5, thereby reducing the maintenance frequency of the sorting unit I and improving the sorting accuracy of the sorting unit I.

[0061] The length direction is Figure 1 The X direction in the width direction is Figure 1 The Y direction in the height direction is Figure 1 The Z direction in .

[0062] In this embodiment, a first assembly cavity A is formed between the rack 1 and the first sorting platform 3. The first assembly cavity A can effectively protect the first clutch device 2 without affecting the normal operation of the first clutch device 2.

[0063] Due to the provision of the first assembly cavity A, the first clutch device 2 can be embedded in the outline of the frame 1 , so the first clutch device 2 does not affect the height layout of the frame 1 .

[0064] At the same time, one side opening of the first assembly chamber A is shielded by the first sorting platform 3. The first sorting platform 3 itself has a requirement for its own extension length along the width direction of the sorting unit I. Therefore, even if the provision of the first assembly chamber A and the first clutch device 2 causes the size of the frame 1 along the width direction of the sorting unit I to increase, it will not protrude beyond the vertical projection outline of the first sorting platform 3. Therefore, the first clutch device 2 will not affect the overall layout of the sorting unit I.

[0065] Since the first assembly cavity A is entirely embedded in the outline of the frame 1, the sorting unit I is cleverly utilized as a component of the first assembly cavity A, so that after the first clutch device 2 is assembled, it will neither occupy space outward in the width direction of the sorting unit I, nor occupy space in the height direction of the sorting unit I, nor occupy space in the length direction of the sorting unit I. Therefore, the sorting unit I will not appear bloated, which is conducive to improving the structural compactness and aesthetics of the sorting unit I, and will not affect the upper packaging platform and the lower packaging grid of the sorting unit I, thereby not reducing the utilization rate of the site where the sorting unit I is located, improving the rationality of the layout of the sorting unit I, further improving the overall performance of the sorting unit I, and thus improving the performance of the sorting and transportation system.

[0066] The Sorting and Transport System I of this embodiment improves the existing Sorting Unit I in terms of sorting efficiency, sorting accuracy, maintenance frequency, and layout rationality, effectively ensuring the performance of Sorting Unit I. As the performance of Sorting Unit I improves, the cost of express delivery sorting will also be reduced, thus facilitating the development and promotion of automated express delivery sorting and providing a partial hardware foundation for the realization of unmanned express delivery sorting stations.

[0067] Specifically, the first driving wheel 5 is an elastic wheel. When the first driving wheel 5 is in frictional contact with the friction segment 201, the first driving wheel 5 itself will be deformed, so that the first driving wheel 5 has a first contact surface in contact with the friction segment 201, that is, there is surface contact between the first driving wheel 5 and the friction segment 201, thereby increasing the friction coefficient between the first driving wheel 5 and the friction segment 201, preventing the first driving wheel 5 from slipping and improving the driving accuracy of the first sorting platform 3.

[0068] Specifically, the first sorting platform 3 includes a roller assembly, which includes two rollers and a belt for linking the two rollers, and a sorting area is formed above the belt.

[0069] In this embodiment, the frame 1 includes a main frame 101, a first connecting member 102, a second connecting member 103 and a third connecting member 104. The first connecting member 102 and the third connecting member 104 both extend along the width direction of the sorting unit I and are both connected to the main frame 101. The second connecting member 103 extends along the length direction of the main frame 101 and connects the first connecting member 102 and the third connecting member 104; the first sorting platform 3 is rotatably provided on the frame 1, the first connecting member 102, the second connecting member 103, the third connecting member 104 and the main frame 101 form a frame, the first sorting platform 3 blocks the top opening of the frame to form a first assembly chamber A, the first clutch device 2 is located within the outline surrounded by the frame, and the first rotating shaft 4 is rotatably connected to the main frame 101.

[0070] In this embodiment, the first connecting member 102, the second connecting member 103, the third connecting member 104 and the main frame 101 together form a frame-like structure. The top of the frame is blocked by the first sorting platform 3 to form a first assembly cavity A. Such an arrangement can ensure that no additional unnecessary components are included in the frame 1 under the premise of forming the first assembly cavity A, which is beneficial to reducing the curb weight of the frame 1, thereby facilitating the lightweighting of the sorting unit I, improving the performance of the sorting unit I, and thereby improving the performance of the sorting and transportation system.

[0071] Specifically, the main frame 101 can be set to a rectangular shell shape to facilitate the setting of the first rotating shaft 4, the first connecting member 102 and the second connecting member 103 can be set to a plate shape, and the third connecting member 104 can be set to a rod connected to the main frame 101, and multiple vertically arranged rods form a side wall of the first assembly cavity A.

[0072] In this embodiment, the sorting unit I also includes a second rotating shaft 6 that is rotatably connected to the frame 1 and coaxial with the first rotating shaft 4; the first rotating shaft 4 is rotatably connected to the frame 1 and extends along the width direction of the sorting unit I, and extends to the first assembly cavity A, and the first assembly cavity A is arranged along the axial direction of the first rotating shaft 4; the axis of the first rotating shaft 4 extends along the width direction of the sorting unit I; the first driving wheel 5 is connected to the first rotating shaft 4 and is coaxial with the first rotating shaft 4, and the first driving wheel 5 can support the frame 1 by supporting the first rotating shaft 4; the first clutch device 2 includes a torque input part 21, a support part 22 and a torque output part, the torque input part 21 is connected to the first rotating shaft 4 or the first driving wheel 5, the support part 22 is connected to the frame 1, and the torque output part is connected to the second rotating shaft 6; the first clutch device 2 can disconnect or combine the drive connection relationship between the first rotating shaft 4 and the second rotating shaft 6; the second rotating shaft 6 maintains a drive connection with the first sorting platform 3.

[0073] In this embodiment, the first rotating shaft 4 can serve as the supporting shaft of the frame 1, and the first driving wheel 5 can be frictionally rotated when the sorting unit I is in operation. Moreover, since the torque input part 21 of the first clutch device 2 is connected to the first rotating shaft 4 or the first driving wheel 5, and the first rotating shaft 4 serves as a load-bearing shaft, the first rotating shaft 4 is allowed to bear a larger torque. When the load on the first sorting platform 3 is large, the first rotating shaft 4 will not be deformed, and the first clutch device 2 can still maintain reliable and stable operation, thereby further improving the performance of the sorting unit I and thus improving the performance of the sorting and transportation system.

[0074] The supporting portion 22 of the first clutch device 2 is supported on the frame 1 , such as on the second connecting member 103 . A groove can be provided on the plate-shaped second connecting member 103 so that the supporting portion 22 is connected to the groove.

[0075] This technical solution integrates the load-bearing shaft of the sorting unit I and the torque input shaft of the first clutch device 2 into the first rotating shaft 4, thereby further improving the structural compactness of the sorting unit I, reducing the overall cost of the sorting unit I, improving the performance of the sorting unit I, and thereby improving the performance of the sorting and transportation system.

[0076] The second rotating shaft 6 can be configured to be rotatably connected to the second connecting member 103. The first clutch device 2 is used to disconnect or connect the driving connection between the first rotating shaft 4 and the second rotating shaft 6. When the first clutch device 2 is switched to the closed state, the second rotating shaft 6 can operate in conjunction with the first rotating shaft 4, and thus can drive the first sorting platform 3 to operate through the second rotating shaft 6; when the first clutch device 2 is switched to the disconnected state, the torque transmission between the second rotating shaft 6 and the first rotating shaft 4 is disconnected, and the first sorting platform 3 will stop operating.

[0077] The second rotating shaft 6 is rotatably connected to the frame 1 and maintains a driving connection with the first sorting platform 3. The first clutch device 2 can switch between an engaged state in which the driving connection between the first rotating shaft 4 and the second rotating shaft 6 is established, and a disengaged state in which the driving connection between the first rotating shaft 4 and the second rotating shaft 6 is disconnected, thereby operating or stopping the first sorting platform 3.

[0078] By controlling the working timing and working duration of the first clutch device 2 , the operating state of the first sorting platform 3 can be controlled.

[0079] In this embodiment, the sorting transport line II also includes a support section 202, and the operation drive system of the sorting unit I also includes a support wheel 15 vertically hinged on the frame 1, and the support wheel 15 can be supported on the support section 202 to support the sorting unit I; the first drive wheel 5 and the support wheel 15 are staggered along the axial direction of the first rotating shaft 4.

[0080] In this embodiment, the support wheel 15 is configured to be vertically rotatable so that the support wheel 15 matches the turning condition of the sorting unit I. The support wheel 15 can cooperate with the first drive wheel 5 to jointly support the frame 1, thereby improving the operating stability of the sorting unit I, further improving the performance of the sorting unit I, and thereby improving the performance of the sorting and transportation system.

[0081] At the same time, the first driving wheel 5 and the support wheel 15 are staggered along the axis of the first rotating shaft 4, thereby avoiding contact between the support wheel 15 and the friction segment 201, thereby increasing the service life of the support wheel 15 and the friction segment 201.

[0082] In this embodiment, the hardness and wear resistance of the support wheel 15 are greater than those of the first drive wheel 5, and the friction coefficient of the support wheel 15 is less than that of the first drive wheel 5, which can reduce the wear of the first drive wheel 5 and increase the service life of the first drive wheel 5 and the support wheel 15.

[0083] Specifically, the first driving wheel 5 and the supporting wheel 15 are both configured as rubber-coated wheels.

[0084] More specifically, the first drive wheel 5 can be a polylactone-coated wheel, and the support wheel 15 can be a polyurethane-coated wheel. Polylactone-coated wheels have advantages such as a high friction coefficient and good elasticity. This material not only provides a sufficient friction coefficient when in contact with the friction segment 201, but also ensures that the first contact surface of the first drive wheel 5 with the friction segment 201 has a sufficient area, further preventing the first drive wheel 5 from slipping on the friction segment 201, thereby improving the operational stability and accuracy of the sorting unit I.

[0085] The polyurethane rubber-coated wheel material has the advantages of high hardness, good wear resistance and low operating noise. The use of the support wheel 15 of this material is conducive to reducing the operating noise of the sorting unit I and improving the quietness of the driving system of the sorting unit I during operation.

[0088] The sorting and transporting line II further includes a base body 203 , on which both the friction segment 201 and the support segment 202 can be detachably connected; the friction segment 201 and the support segment 202 are both configured as sheet structures.

[0089] In this embodiment, the friction section 201 and the support section 202 are sheet structures detachably connected to the base 203. Since the friction section 201 and the support section 202 play the actual supporting role of the sorting and transporting line II, targeted designs including structure, strength and surface roughness are made for the two, so that the sorting and transporting line II can meet actual usage requirements, and the base 203 can be used as a fixed support frame. The base 203 can then be set to an ordinary steel frame or even a wooden structure to reduce the curb weight and production cost of the sorting and transporting line II, thereby improving the performance of the sorting and transporting system.

[0090] Specifically, the friction section 201 and the support section 202 may both be configured as steel sheets connected to the base 203 via countersunk bolts, and the friction coefficient of the friction section 201 may be configured to be greater than the friction coefficient of the support section 202 .

[0091] Example 3:

[0092] Reference Figure 7 and Figure 8 In addition to all the technical solutions of the above-mentioned embodiment 2, the embodiment of the present utility model further has the following technical solutions:

[0093] The support section 202 is a closed loop connected end to end; in the operating range and stagnant range of the sorting platform, the support wheel 15 remains supported on the support section 202 to support the sorting unit I; the support section 202 includes a straight portion 2031, and the friction section 201 extends along the extension direction of the straight portion 2031.

[0094] In this embodiment, the support section 202 is a closed loop. In the operating range and stagnant range of the sorting platform, the support wheel 15 always remains supported on the support section 202 to ensure the operational stability of the sorting unit I. In the operating range of the sorting platform, the first drive wheel 5 also remains in friction contact with the friction section 201, but the first drive wheel 5 does not provide the main supporting force for the sorting unit I.

[0095] The operating range of the sorting platform corresponds to the position of the straight portion 2031 of the support section 202. Within the operating range of the sorting platform, the sorting platform works by loading or unloading packages. The linear operating range facilitates the arrangement of the loading and unloading devices, facilitates the realization of two-way loading and unloading, and improves the express sorting efficiency.

[0096] In this embodiment, the sorting and transporting line II further includes a third slope 207 connected to the friction section 201 to guide the support wheel 15 toward or away from the friction section 201 .

[0097] In this embodiment, in both the operating range and the stagnant range of the sorting platform, the support section 202 always supports the support wheel 15 to support the sorting unit I. The third slope 207 is used to guide the first drive wheel 5 from the suspended position to the friction section 201, or to guide the first drive wheel 5 from the friction section 201 to the suspended position, so as to avoid the first drive wheel 5 from stalling during operation, thereby ensuring the operational stability of the sorting platform and the sorting unit I.

[0098] Specifically, the cross section of the third slope 207 can be set to be a right-angled trapezoid and welded to the friction section 201 .

[0099] More specifically, the third slope 207 has an end close to the friction section 201 that slopes upward, and an end away from the friction section 201 that slopes downward.

[0100] Example 4:

[0101] Reference Figure 4-Figure 6 ,as well as Figure 9 and Figure 10 In addition to all the technical solutions of the above-mentioned embodiment 2, the embodiment of the present utility model further has the following technical solutions:

[0102] Multiple friction segments 201 and multiple support segments 202 are staggered and connected to form a ring-shaped sorting transport line II; within the operating range of the sorting platform, the support wheel 15 remains separated from the friction segment 201 and the support segment 202, and at the same time, the first drive wheel 5 is supported on the friction segment 201 to support the sorting unit I; within the stagnant range of the sorting platform, the support wheel 15 remains supported on the support segment 202 to support the sorting unit I; the friction segment 201 is set as a straight segment, and the support segment 202 is set as a curved segment.

[0103] In this embodiment, the support section 202 and the friction section 201 are interlaced and connected to form a ring-shaped sorting transport line II. The support section 202 supports the support wheel 15 to support the sorting unit I in the stagnant area of the sorting platform, and supports the sorting unit I through the first drive wheel 5 in the operating area of the sorting platform. In this way, it can be ensured that the first drive wheel 5 applies sufficient positive pressure to the friction section 201 to ensure that the first drive wheel 5 does not slip during operation while supporting the sorting unit I, thereby further improving the driving accuracy of the sorting platform.

[0104] After separating from the supporting section 202 , the support wheel 15 will also enter a suspended position separated from the sorting and transporting line II, so that the support wheel 15 will not be supported on the sorting and transporting line II all the time, thereby reducing the friction loss of the support wheel 15 .

[0105] In this embodiment, the friction segment 201 is configured as a straight segment, and the support segment 202 is configured as a curved segment.

[0106] In this embodiment, the operating range of the sorting platform is a straight segment, and the stagnant range of the sorting platform is a curved segment. Within the operating range of the sorting platform, the working action of the sorting platform is loading or unloading packages. The straight segment can facilitate the arrangement of the loading and unloading devices, and the curved segment can ensure that the sorting transport line II can form a loop.

[0107] In this embodiment, the sorting transport line II also includes a parallel section 204, a first side of the parallel section 204 is connected to an end of the friction section 201 close to the parallel section 204, and a second side of the parallel section 204 is connected to an end of the support section 202 close to the parallel section 204; when the sorting unit I runs to the parallel section 204, the first driving wheel 5 is supported on the first side of the parallel section 204, and the support wheel 15 is supported on the second side of the parallel section 204.

[0108] In this embodiment, the parallel section 204 is used to realize the transition when the first driving wheel 5 and the support wheel 15 cooperate or disengage with the corresponding friction section 201 and the running section. When the working condition of one of the first driving wheel 5 and the support wheel 15 supporting the sorting unit I is switched to the working condition of the other of the first driving wheel 5 and the support wheel 15 supporting the sorting unit I, a bearing platform is provided to simultaneously support the first driving wheel 5 and the support wheel 15, thereby ensuring the operating stability of the sorting unit I when the working condition is switched.

[0109] Specifically, the parallel section 204 can be configured as an integral platform, the upper surface of which is used to support the first driving wheel 5 and the supporting wheel 15 .

[0110] More specifically, the first side of the parallel segment 204 may be set as the inner side of the parallel segment 204 relative to the loop line, and the second side of the parallel segment 204 may be set as the outer side of the parallel segment 204 relative to the loop line.

[0111] In this embodiment, the sorting transport line II further includes a first slope 205 and a second slope 206 connected to the parallel section 204 to guide the first driving wheel 5 and the supporting wheel 15 toward or away from the parallel section 204 .

[0112] In this embodiment, the first slope 205 and the second slope 206 are both connected to the parallel section 204. When the first driving wheel 5 and the support wheel 15 run from the suspended position to the parallel section 204, or run from the parallel section 204 to the suspended position of the first driving wheel 5 and the support wheel 15, the first slope 205 and the second slope 206 respectively guide the first driving wheel 5 and the support wheel 15 to avoid the first driving wheel 5 and the support wheel 15 from stalling during operation, thereby ensuring the operational stability of the sorting platform and the sorting unit I.

[0113] Specifically, the cross-sections of the first slope 205 and the second slope 206 can both be set to be right-angled trapezoids, and can be welded to the parallel section 204 .

[0114] More specifically, the first slope 205 and the second slope 206 are inclined upward at one end close to the parallel section 204 , and inclined downward at one end away from the parallel section 204 .

[0115] Example 5:

[0116] Reference Figure 11-13 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0117] The sorting unit I further includes a second sorting platform 7 rotatably arranged on the frame 1 . The second sorting platform 7 is vertically stacked with the first sorting platform 3 and is further away from the first rotating shaft 4 than the first sorting platform 3 .

[0118] In this embodiment, the second sorting platform 7 is vertically stacked above the first sorting platform 3, and a certain distance is reserved between the two to ensure that the first sorting platform 3 has sufficient transportation space.

[0119] The second sorting platform 7 and the first sorting platform 3 are configured to have the same structure. Both the first sorting platform 3 and the second sorting platform 7 are supported on the first connecting member 102, such as by bolt connection.

[0120] By setting up an additional second sorting platform 7, the sorting efficiency of the sorting unit I can be increased exponentially, thereby reducing the sorting cost of express delivery.

[0121] Furthermore, since the first sorting platform 3 and the second sorting platform 7 are independent of each other, they can independently perform express sorting operations, which makes the use flexibility of the sorting unit I better.

[0122] In this embodiment, the sorting unit I also includes a third rotating shaft 9 and a fourth rotating shaft 10 connected to the frame 1 and coaxially, and the third rotating shaft 9 is parallel to the axis of the first rotating shaft 4 and / or the second rotating shaft 6; the sorting unit I also includes a second clutch device 11, and the second clutch device 11 has the same structure as the first clutch device 2.

[0123] In this embodiment, the second sorting platform 7 adopts the same control method as the first sorting platform 3, that is, the operating state of the second sorting platform 7 is controlled by controlling the state of the second clutch device 11. This improves the integrity of the sorting unit I and the versatility of its parts, thereby reducing the procurement and assembly costs of the sorting unit I, thereby reducing the overall cost of the sorting unit I.

[0124] In this embodiment, the second rotating shaft 6 and the fourth rotating shaft 10 are provided as two respectively located at the ends of the first rotating shaft 4 and the third rotating shaft 9 , and the first clutch device 2 and the second clutch device 11 are provided as two groups corresponding to the second rotating shaft 6 and the fourth rotating shaft 10 .

[0125] In this embodiment, the sorting unit I further includes a first transmission device 12 and a second transmission device 13, which respectively establish a driving connection relationship between the second rotating shaft 6 and the first sorting platform 3, and between the fourth rotating shaft 10 and the second sorting platform 7. The first transmission device 12 and the second transmission device 13 are also provided in two groups, which respectively establish a driving connection relationship between the corresponding second rotating shaft 6 and the first sorting platform 3, and between the corresponding fourth rotating shaft 10 and the second sorting platform 7. The torque output directions of the two groups of first transmission devices 12 are opposite, and the torque output directions of the two groups of second transmission devices 13 are also opposite, so that the first sorting platform 3 and the second sorting platform 7 can both operate in the forward direction and the reverse direction.

[0126] In this embodiment, the first sorting platform 3 corresponds to two sets of first clutch devices 2 , and the second sorting platform 7 also corresponds to two sets of second clutch devices 11 .

[0127] When one first clutch device 2 is closed, the first sorting platform 3 can rotate forward, and when the other first clutch device 2 is closed, the first sorting platform 3 can rotate reverse.

[0128] When one second clutch device 11 is closed, the second sorting platform 7 can rotate forward, and when the other second clutch device 11 is closed, the second sorting platform 7 can rotate reversely.

[0129] The first clutch device 2 and the second clutch device 11 are independent of each other, and their working states will not be affected by each other, thereby ensuring the flexibility and reliability of the sorting unit I.

[0130] The first clutch device 2 and the second clutch device 11 are arranged at both ends of the first rotating shaft 4 and the third rotating shaft 9 respectively. The second rotating shaft 6 is supported on the second connecting member 103. A mounting plate extends from the first connecting member 102, and the mounting plate is used to support the second sorting platform 7.

[0131] Each pair of coaxial first and second clutch devices 2 and 11 share a first rotating shaft 4 and a third rotating shaft 9. The torque input portions 21 of the two first clutch devices 2 receive torque in the same direction, and the torque input portions 21 of the two second clutch devices 11 also receive torque in the same direction. The torques are then reversed through the corresponding first transmission devices 12, thereby causing the torques output by the two first clutch devices 2 and received by the first sorting platform 3 to rotate in opposite directions. Torques in opposite directions are thus generated, enabling the two first clutch devices 2 to control the forward or reverse rotation of the first sorting platform 3.

[0132] In this embodiment, the first transmission device 12 and the second transmission device 13 both include a first transmission assembly and a second transmission assembly that are driven and connected to each other, the first transmission assembly can change the output direction of the torque, and the second transmission assembly can transmit the torque in parallel; the first transmission assembly includes a bevel gear transmission assembly, and the second transmission assembly includes one of a sprocket chain transmission assembly and a belt transmission assembly.

[0133] By adjusting the meshing direction of the bevel gear assembly, the direction of its output torque can be changed, thereby enabling the first transmission device 12 to achieve the desired torque reversal.

[0134] The bevel gear transmission assembly can be configured as a spiral gear to improve the stability of torque transmission.

[0135] Specifically, both the first transmission device 12 and the second transmission device 13 include two transmission assemblies. One is a bevel gear transmission assembly, which includes bevel gears and an intermediate shaft. The driving bevel gear is connected to the corresponding second rotating shaft 6 or fourth rotating shaft 10, and the intermediate shaft is rotatably connected to the frame 1. The other is a sprocket chain transmission assembly, which transmits the torque of the intermediate shaft to the torque input port of the corresponding first sorting platform 3 or second sorting platform 7.

[0136] The transport directions of the first sorting platform 3 and the second sorting platform 7 are both along the width direction of the sorting unit I. Therefore, the axes of the rollers of the first sorting platform 3 and the second sorting platform 7 extend along the length direction of the sorting unit I. Figure 11 The first transmission device 12 and the second transmission device 13 are arranged in the form of .

[0137] Specifically, the first clutch device 2 and the second clutch device 11 can both be configured as electromagnetic clutches or magnetic powder clutches, which can be powered by a battery provided on the frame 1, or by establishing an electrical connection with an external power grid through brushes and powered by the external power grid.

[0138] By controlling the working timing and working duration of the first clutch device 2 and the second clutch device 11 , the operating states of the first sorting platform 3 and the second sorting platform 7 can be controlled.

[0139] Example 6:

[0140] In addition to all the technical solutions of the above-mentioned embodiment 5, the embodiment of the present utility model further has the following technical solutions:

[0141] The sorting unit I also includes a second drive wheel connected to both ends of the third rotating shaft 9, and the second drive wheel can support the frame 1 by supporting the third rotating shaft 9; the torque input part 21 of the second clutch device 11 is connected to the third rotating shaft 9 or the second drive wheel, the support part 22 of the second clutch device 11 is connected to the frame 1, and the torque output part of the second clutch device 11 is connected to the fourth rotating shaft 10; the second drive wheel and the second clutch device 11 are located in a second assembly cavity with the same structure as the first assembly cavity A.

[0142] In the operating range of the second sorting platform 7, the second drive wheel maintains frictional contact with the friction segment 201 to enable the second drive wheel to operate; in the stagnant range of the second sorting platform 7, the second drive wheel remains disengaged from the friction segment 201 to enable the second drive wheel to be suspended in the air; the second drive wheel and the support wheel 15 are staggered along the axial direction of the third rotating shaft 9.

[0143] In this embodiment, the second driving wheel is used as the driving component of the third rotating shaft 9 , and the second driving wheel also operates through friction contact with the friction segment 201 .

[0144] At the same time, the second driving wheel and the support wheel 15 are staggered along the axis of the third rotating shaft 9, thereby avoiding contact between the support wheel 15 and the friction segment 201, thereby increasing the service life of the support wheel 15 and the friction segment 201.

[0145] The second driving wheel and the first driving wheel 5 share a friction section 201 to reduce the cost of the sorting and transporting system.

[0146] In this embodiment, the third rotating shaft 9 is arranged horizontally relative to the first rotating shaft 4, that is, the third rotating shaft 9 and the first rotating shaft 4 are in the same horizontal plane, and the third rotating shaft 9 adopts the same form as the first rotating shaft 4 to obtain the initial torque. The third rotating shaft 9 can also serve as the support shaft of the frame 1, and the second driving wheel can be frictionally rotated when the sorting unit I is running.

[0147] Specifically, the second drive wheel has the same structure as the first drive wheel 5, and the tangents of all the first drive wheels 5 and all the second drive wheels are in the same horizontal plane, so as to ensure that all the first drive wheels 5 and all the second drive wheels can operate by rubbing against the same plane, and the second drive wheel and the second clutch device 11 are located in the second assembly cavity with the same structure as the first assembly cavity A, which can also ensure the structural compactness of the sorting unit I and thus ensure the performance of the sorting unit I.

[0148] More specifically, the second assembly cavity with the same structure defined in this embodiment can be understood as a symmetrical structure of the first assembly cavity, with the axis of symmetry being the center line of the length direction of the main frame 101. The second assembly cavity and the first assembly cavity A share a main frame to form a side wall of the cavity, and the accompanying drawings will not provide detailed description.

[0151] The torque input portion 21 of the second clutch device 11 is connected to the third rotating shaft 9, the support portion 22 of the second clutch device 11 is connected to the frame 1, and the torque output portion of the second clutch device 11 is connected to the fourth rotating shaft 10; the sorting unit I also includes a third transmission device 8, and the third rotating shaft 9 and the first rotating shaft 4 are drivenly connected through the third transmission device 8; the third transmission device 8 includes one of a synchronous belt drive assembly, a sprocket chain drive assembly, a gear drive assembly and a belt drive assembly.

[0152] The torque of the third rotating shaft 9 comes from the first rotating shaft 4, which can cleverly utilize the distance that must be reserved between the two, thereby improving the structural compactness of the sorting unit I.

[0153] The third transmission device 8 includes one of a synchronous belt transmission assembly, a sprocket chain transmission assembly, a gear transmission assembly and a belt transmission assembly to ensure the stability and reliability of torque transmission between the first rotating shaft 4 and the third rotating shaft 9.

[0154] Specifically, in this embodiment, the first rotating shaft 4 and the third rotating shaft 9 are vertically stacked.

[0155] Example 8:

[0156] Reference Figure 11-13 In addition to all the technical solutions of the above-mentioned embodiment 6 or 7, the embodiment of the present utility model further has the following technical solutions:

[0157] The sorting unit I further includes two groups of sleeves 14 , both of which are connected to the frame 1 , and the two groups of sleeves 14 are arranged in parallel, and the first rotating shaft 4 and the third rotating shaft 9 are rotatably connected in the corresponding sleeves 14 .

[0158] In this embodiment, the first rotating shaft 4 and the second rotating shaft 6 are rotatably connected in the sleeve 14. During assembly, the sleeve 14 can be assembled to the frame 1, such as the main frame 101. In this way, the frame 1 does not need to be fine-machined for the first rotating shaft 4 and the second rotating shaft 6, as long as it can meet the requirements of installing the sleeve 14. In this way, the overall cost of the sorting unit I can be reduced.

[0159] Specifically, when the third rotating shaft 9 adopts the arrangement form in Example 6, the two sleeves 14 are both installed on the main frame 101.

[0160] When the third rotating shaft 9 adopts the arrangement form of Example 7, the sleeve 14 of the first rotating shaft 4 is installed on the main frame 101, a connecting rod extends from the main frame 101, and the sleeve 14 of the second rotating shaft 6 is installed on the connecting rod.

[0161] Example 9:

[0162] Reference Figure 14 and Figure 15 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0163] A plurality of sorting units I connected end to end form a sorting assembly, so that the sorting planes of all first sorting platforms 3 and all second sorting platforms 7 in one sorting assembly are continuous; the plurality of sorting assemblies are hinged end to end along the vertical axis and then run along the line body II, so as to improve the continuity of the express sorting operation and improve the express sorting efficiency.

[0164] In this embodiment, the sorting planes of the sorting units I in the sorting assembly are continuous with each other, so that all the sorting planes of each sorting assembly can form an extra-large platform. In this way, the sorting assembly can be used to transport large express parcels, thereby improving the adaptability of the sorting and transport line II to the size of the express parcels.

[0165] Specifically, adjacent sorting units I in a sorting assembly can be connected by bolts, and adjacent sorting assemblies can be connected by spherical bearings.

[0166] More specifically, since the loop line is bound to have curved parts, the number of sorting units I included in the sorting assembly should not be too large, so as to ensure that the first driving wheel 5 in the sorting unit I and the sorting transport line II on the line body II are as consistent as possible, that is, the plane where the first driving wheel 5 rotates is as parallel as possible to the extension plane of the length direction of the line body II.

[0167] In one technical solution of the present invention, the sorting and transporting line II also includes a linear motor device, which includes a moving part B and a fixed part. The fixed part is arranged on the line body II; the moving part B is arranged on the frame 1.

[0168] The frame 1 has a storage cavity in which a control system can be arranged. The storage cavity can be formed inside the main frame 101, and the control system is arranged in the storage cavity to further improve the structural compactness of the sorting unit I.

[0169] The front and rear sides of the frame 1 are provided with connection holes Q for arranging the wiring harness, that is, the front and rear sides of the main frame body 101 are reserved with wiring harness openings for the wiring harness to pass through, which are used to arrange the wiring harness. This wiring harness arrangement can well limit the bending direction and bending formation of the wiring harness when the sorting unit I turns, thereby avoiding the problem of wire breakage caused by large-angle bending of the wiring harness, thereby improving the service life of the wiring harness.

[0170] It can be understood that, except for any conflicting parts, the above-mentioned embodiments 1-9 can be freely combined to form other implementation methods of the present invention.
