Description

Technical Field

[0001] The present invention relates to the technical field of express sorting, and particularly to a sorting and transportation system. Background Art

[0002] The sorting unit is a logistics sorting device, and the execution device of the sorting unit is a sorting platform. To improve the sorting efficiency of the sorting unit, it is necessary to ensure the self-performance of the sorting unit. The self-performance of the sorting unit includes structural compactness, service life, layout rationality, maintenance frequency, sorting accuracy, etc.

[0003] Currently, the sorting platform is often set as an electric drive type, which includes a motor, two rollers, and a belt for linking the two rollers. The motor drives one roller to run. Since the sorting unit needs to run for a long time, the motor is prone to damage after long-term operation, making it difficult to reduce the maintenance frequency of the sorting platform and also reducing the express sorting efficiency. Even if the operation of the sorting platform is controlled through a mechanical structure in cooperation with a clutch device, however, since the clutch device is often set in an exposed form, the exposed clutch device will also occupy a part of the space outside the frame of the sorting unit, which will affect the upper bagging table and the lower bagging grid, limit the layout rationality 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 in cooperation with a clutch device to operate the sorting platform utilizes the operating actions of the sorting unit to drive the sorting platform to rotate 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 has an operating requirement in specific parts of the sorting and transportation line, such as the upper bagging and lower bagging parts, and the first driving wheel, as the support wheel of the sorting unit, needs to always support on the sorting and transportation line. Therefore, when the sorting platform has no operating requirement, the first driving wheel has unnecessary wear, reducing the service life of the first driving wheel and also making the first driving wheel more likely to slip on the sorting and transportation line, which is not conducive to improving the operation accuracy of the sorting platform, reducing the service life of the sorting unit, increasing the maintenance frequency of the sorting unit, and also reducing the performance of the sorting unit, and thus reducing the performance of the sorting and transportation system. Summary of the Invention

[0005] (1) Technical Problems to be Solved

[0006] In view of the above-mentioned disadvantages and deficiencies of the prior art, the present invention provides a sorting and transportation system, which solves the technical problem that the performance of the sorting unit and even the sorting and transportation system is low due to high maintenance frequency, low service life, poor layout rationality, and low sorting accuracy in the prior art.

[0033] (III) Beneficial effects

[0034] The beneficial effects of the present invention are as follows: For 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 operating requirement, it is the operating interval of the first sorting platform; when the first sorting platform has no operating requirement, it is the stagnation interval of the first sorting platform. Only within the operating interval of the first sorting platform, the first driving wheel remains in contact with the friction section, while within the stagnation interval of the first sorting platform, the first driving wheel disengages 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. This first assembly cavity can effectively protect the first clutch device and will not affect the normal operation of the first clutch device;

[0036] Due to the setting of this first assembly cavity, the first clutch device can be embedded within the contour of the frame. Therefore, the first clutch device will not affect the height layout of the frame.

[0037] At the same time, one side of the first assembly cavity is open and is blocked by the first sorting platform. The first sorting platform itself has a requirement for its extension length along the width direction of the sorting unit. Therefore, even if the setting of the first assembly cavity and the first clutch device causes an increase in the size of the frame along the width direction of the sorting unit, it will not protrude beyond the vertical projection contour 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 implementation manners

[0057] For better explaining the present invention for easy understanding, the following combines the attached Figures 1 - 15 drawings and describes the present invention in detail through specific implementation manners. Among them, the orientation nouns such as "upper" and "lower" mentioned in this article are based on Figure 1 the orientation of the attached drawings.

[0058] Embodiment 1:

[0059] Refer to Figures 1 - 10, an embodiment of the present invention provides a sorting and transportation system, including a sorting unit Ⅰ and a sorting and transportation line Ⅱ. 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 further 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 contour 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, the first sorting platform 3 can be switched between an operating interval and a stagnant interval; within the operating interval of the first sorting platform 3, the first driving wheel 5 remains in frictional contact with the friction section 201 to make the first driving wheel 5 rotate; within the stagnant interval of the first sorting platform 3, the first driving wheel 5 remains disengaged from the friction section 201 to make the first driving wheel 5 suspended.

[0060] In this embodiment, the first sorting platform 3 is driven to run by the first rotating shaft 4. When the first sorting platform 3 has an operating requirement, it is the operating interval of the first sorting platform 3; when the first sorting platform 3 has no operating requirement, it is the stagnant interval of the first sorting platform 3. Only within the operating interval of the first sorting platform 3 does the first driving wheel 5 remain in contact with the friction section 201, while within the stagnant interval of the first sorting platform 3, the first driving wheel 5 disengages from the friction section 201 and remains suspended to avoid 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 Figure 1 the Y direction in Figure 1 the Z direction in.

[0062] In this embodiment, a first assembly cavity A is formed between the frame 1 and the first sorting platform 3. The first assembly cavity A can effectively protect the first clutch device 2 and does not affect the normal operation of the first clutch device 2;

[0063] Due to the setting of this first assembly cavity A, the first clutch device 2 can be embedded in the contour 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 body 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 body 101. The second connecting member 103 extends along the length direction of the main frame body 101 and connects the first connecting member 102 and the third connecting member 104. The first sorting platform 3 is rotatably arranged on the frame 1. The first connecting member 102, the second connecting member 103, the third connecting member 104, and the main frame body 101 form a frame. The first sorting platform 3 covers the top opening of the frame to form a first assembly cavity A. The first clutch device 2 is located within the contour surrounded by the frame. The first rotating shaft 4 is rotatably connected to the main frame body 101.

[0070] In this embodiment, the first connecting member 102, the second connecting member 103, the third connecting member 104, and the main frame body 101 together form a structure similar to a frame. The top of the frame is covered by the first sorting platform 3 to form a first assembly cavity A. With this setting, on the premise of forming the first assembly cavity A, there are no additional unnecessary components in the frame 1, which is beneficial to reducing the overall mass of the frame 1, and further beneficial to realizing the lightweight of the sorting unit I, improving the performance of the sorting unit I, and thus improving the performance of the sorting and transportation system.

[0071] Specifically, the main frame body 101 can be set as 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 as plate shapes. The third connecting member 104 can be set as a rod connected to the main frame body 101. Multiple vertically arranged rods form one side wall of the first assembly cavity A.

[0072] In this embodiment, the sorting unit I further includes a second rotating shaft 6 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 into the first assembly cavity A. The first assembly cavity A is arranged along the axis 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. 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. The torque output part is connected to the second rotating shaft 6. The first clutch device 2 can disconnect or combine the driving connection relationship between the first rotating shaft 4 and the second rotating shaft 6. The second rotating shaft 6 maintains a driving 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.

[0086] Example 2:

[0087] Reference Figures 4 - 10 In addition to all the technical solutions of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[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-like structures detachably connected to the base body 203. Since the friction section 201 and the support section 202 actually play a supporting role in the sorting and transportation line II, targeted designs including structure, strength, and surface roughness for the two can enable the sorting and transportation line II to meet the actual use requirements. By setting the base body 203 as a fixed support frame, the base body 203 can be set as an ordinary steel frame or even a wooden structure, so as to reduce the overall mass and production cost of the sorting and transportation line II, and further improve the performance of the sorting and transportation system.

[0090] Specifically, both the friction section 201 and the support section 202 can be set as steel sheets connected to the base body 203 by countersunk bolts, and the friction coefficient of the friction section 201 can be set to be greater than that of the support section 202.

[0091] Embodiment 3:

[0092] Referring to Figure 7 and Figure 8 In addition to having all the technical solutions of the above Embodiment 2, the embodiments of the present invention further have the following technical solutions:

[0093] The support section 202 is a closed loop connected end to end; within the operating interval and the stagnant interval of the sorting platform, the support wheels 15 always maintain support 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. Within the operating interval and the stagnant interval of the sorting platform, the support wheels 15 always maintain support on the support section 202 to ensure the running stability of the sorting unit I. Within the operating interval of the sorting platform, the first driving wheel 5 also maintains frictional contact with the friction section 201, but the first driving wheel 5 does not provide the main supporting force for the sorting unit I.

[0095] The operating interval of the sorting platform corresponds to the position of the straight portion 2031 of the support section 202. Within the operating interval of the sorting platform, the working action of the sorting platform is to load packages on or off. The straight-shaped operating interval can facilitate the arrangement of the package loading device and the package unloading device, which is beneficial to realizing two-way package loading and two-way package unloading, and also beneficial to improving the express sorting efficiency.

[0096] In this embodiment, the sorting and transportation line II further includes a third ramp 207 connected to the friction section 201 to guide the support wheels 15 to 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 Figures 4 - 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 invention 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 section of the sorting platform is a straight section, and the stagnant section of the sorting platform is a curved section. Within the operating section of the sorting platform, the working action of the sorting platform is to load or unload packages. The straight section facilitates the arrangement of the package loading device and the package unloading device, and the curved section ensures that the sorting and transportation line II can form a loop.

[0107] In this embodiment, the sorting and transportation line II further includes a parallel section 204. One side of the parallel section 204 is connected to one end of the friction section 201 close to the parallel section 204, and the other side of the parallel section 204 is connected to one 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 one side of the parallel section 204, and at the same time, the support wheel 15 is supported on the other side of the parallel section 204.

[0108] In this embodiment, the parallel section 204 is used to achieve 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 the sorting unit I supported by one of the first driving wheel 5 and the support wheel 15 is switched to the working condition supported by the other of the first driving wheel 5 and the support wheel 15, a loading platform is provided to carry the first driving wheel 5 and the support wheel 15 at the same time, thereby ensuring the running stability of the sorting unit I during the working condition switching.

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

[0110] More specifically, one side of the parallel section 204 can be set as the inner side of the parallel section 204 relative to the loop, and the other side of the parallel section 204 can be set as the outer side of the parallel section 204 relative to the loop.

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

[0112] In this embodiment, both the first ramp 205 and the second ramp 206 are 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 ramp 205 and the second ramp 206 respectively play a guiding role for the first driving wheel 5 and the support wheel 15, avoiding jerks during the running of the first driving wheel 5 and the support wheel 15, and thus ensuring the running stability of the sorting platform and the sorting unit I.

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

[0114] More specifically, the first slope 205 and the second slope 206 slope upward near one end of the parallel section 204 and slope downward away from the parallel section 204.

[0115] Embodiment 5:

[0116] Referring to Figures 11 - 13 , in addition to having 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 provided on the frame 1. The second sorting platform 7 is vertically stacked with the first sorting platform 3 and is farther from the first rotating shaft 4 relative to 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 set 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 providing an additional second sorting platform 7, the sorting efficiency of the sorting unit I can be doubled, and the sorting cost of express delivery can be reduced.

[0121] Moreover, since the first sorting platform 3 and the second sorting platform 7 are independent of each other, they can independently perform the express sorting operation, making the sorting unit I have better flexibility in use.

[0122] In this embodiment, the sorting unit I further includes a third rotating shaft 9 and a fourth rotating shaft 10 connected to the frame 1 and coaxial. The axis of 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 further 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, by controlling the state of the second clutch device 11 to control the working state of the second sorting platform 7, so that the integrity of the sorting unit I and the universality between parts are better, which can reduce the procurement cost and assembly cost of the sorting unit I, etc., and further reduce the overall cost of the sorting unit I.

[0124] In this embodiment, the second rotating shaft 6 and the fourth rotating shaft 10 are arranged at both ends of the first rotating shaft 4 and the third rotating shaft 9 respectively, and the first clutch device 2 and the second clutch device 11 are arranged in 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 to 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 both provided in two groups to 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 both the first sorting platform 3 and the second sorting platform 7 can run forward and can also run backward.

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

[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 backward.

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

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

[0131] Every two coaxial first clutch devices 2 and second clutch devices 11 share one first rotating shaft 4 and one third rotating shaft 9. The torque input parts 21 of the two first clutch devices 2 receive torques in the same direction, and the torque input parts 21 of the two second clutch devices 11 also receive torques in the same direction, and the torque is reversed through the corresponding first transmission device 12, so that the rotation directions of the torques output from the two first clutch devices 2 obtained by the first sorting platform 3 are opposite, and torques with opposite rotation directions can be obtained, and thus the two first clutch devices 2 can control the first sorting platform 3 to rotate forward or backward.

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

[0133] By adjusting the meshing direction of the bevel gear assembly, the direction of the output torque can be changed, so that the first transmission device 12 can achieve the purpose of the required torque commutation.

[0134] The bevel gear transmission component can be set as an arc tooth gear to improve the stability of torque transmission.

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

[0136] The transportation directions of both the first sorting platform 3 and the second sorting platform 7 are 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, and the first transmission device 12 and the second transmission device 13 can be arranged in the form of Figure 11 Among them.

[0137] Specifically, both the first clutch device 2 and the second clutch device 11 can be set as electromagnetic clutches or magnetic powder clutches, which can be powered by a battery provided on the frame 1, or can establish an electrical connection relationship with an external power grid through a brush and be 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] Embodiment 6:

[0140] In addition to having all the technical solutions of the above Embodiment 5, the embodiment of the present invention further has the following technical solutions:

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

[0142] Within the operating range of the second sorting platform 7, the second driving wheels remain in frictional contact with the friction section 201 to cause the second driving wheels to rotate. Within the stagnant range of the second sorting platform 7, the second driving wheels remain disengaged from the friction section 201 to suspend the second driving wheels. The second driving wheels and the supporting wheels 15 are arranged offset from each other along the axis of the third rotating shaft 9.

[0143] In this embodiment, the second driving wheels are used as the driving components of the third rotating shaft 9, and the second driving wheels also rotate by frictional contact with the friction section 201.

[0144] Meanwhile, the second driving wheels and the supporting wheels 15 are arranged offset from each other along the axis of the third rotating shaft 9, thereby avoiding contact between the supporting wheels 15 and the friction section 201, and thus improving the service lives of the supporting wheels 15 and the friction section 201.

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

[0146] In this embodiment, the third rotating shaft 9 is horizontally arranged 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. Moreover, the third rotating shaft 9 obtains an initial torque in the same manner as the first rotating shaft 4. The third rotating shaft 9 can also serve as the support shaft of the machine frame 1, and the second driving wheels can be frictionally rotated during the operation of the sorting unit I.

[0147] Specifically, the second driving wheels have the same structure as the first driving wheels 5, and the tangents of all the first driving wheels 5 and all the second driving wheels are in the same horizontal plane to ensure that all the first driving wheels 5 and all the second driving wheels can rotate due to friction with a single plane. Moreover, the second driving wheels and the second clutch device 11 are located in a second assembly cavity having 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 the symmetric structure of the first assembly cavity. The axis of symmetry is the midline in the length direction of the main frame body 101. The second assembly cavity and the first assembly cavity A share a main frame body to form one side wall of the cavity, and no detailed illustration will be given in the drawings.

[0149] Example 7:

[0150] Referring to Figures 11 - 13 , in addition to having all the technical solutions of the above-mentioned Embodiment 5, the embodiment of the present invention further has the following technical solutions:

[0151] The torque input part 21 of the second clutch device 11 is connected to the third rotating shaft 9, the supporting 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 sorting unit I further includes a third transmission device 8, and the third rotating shaft 9 and the first rotating shaft 4 are kept in driving connection through the third transmission device 8; 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.

[0152] The torque of the third rotating shaft 9 comes from the first rotating shaft 4, and the distance that must be reserved between the two can be skillfully utilized, 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 arranged vertically and stacked.

[0155] Example 8:

[0156] Referring to Figures 11 - 13 , in addition to having all the technical solutions of the above-mentioned Embodiment 6 or 7, the embodiment of the present invention further has the following technical solutions:

[0157] The sorting unit I further includes two sets of sleeves 14, the sleeves 14 are both connected to the frame 1, and the two sets 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 on the main frame body 101. In this way, the frame 1 does not need to perform fine machining on the first rotating shaft 4 and the second rotating shaft 6, as long as it can meet the installation of the sleeve 14, so that the overall cost of the sorting unit I can be reduced.

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

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

[0161] Embodiment 9:

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

[0163] Multiple sorting units I connected end to end form a sorting assembly, so that the sorting planes of all the first sorting platforms 3 and all the second sorting platforms 7 in one sorting assembly are continuous; multiple sorting assemblies are hinged end to end along the vertical axis and run along the line body II to improve the continuity of the express sorting operation and 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 the sorting planes of all the sorting units in each sorting assembly can form an ultra-large platform. In this way, the sorting assembly can be used to transport large express items, thereby improving the adaptability of the sorting and transportation line II to the size of express items.

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

[0166] More specifically, since there will inevitably be curved parts in the loop line, the number of sorting units I included in the sorting assembly should not be too large to ensure that the first driving wheels 5 in the sorting units I and the sorting and transportation line II on the line body II are as consistent as possible, that is, the plane where the rotation direction of the first driving wheels 5 is located is as parallel as possible to the extension plane in the length direction of the line body II.

[0167] In a technical solution of the present invention, the sorting and transportation line II further includes a linear motor device, and the linear motor device 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] There is a storage cavity capable of arranging a control system inside the frame 1, and this storage cavity can be formed inside the main frame body 101. The control system is arranged in this storage cavity to further improve the structural compactness of the sorting unit I.

[0169] On the front and rear sides of the frame 1, there are connection holes Q for routing wire harnesses, that is, wire harness openings that meet the requirements for the passage of wire harnesses are reserved on the front and rear sides of the main frame body 101 for arranging wire harnesses. This form of wire harness arrangement can well limit the bending direction and formation of the wire harness when turning in the sorting unit I, thereby avoiding the problem of wire breakage caused by large-angle bending of the wire harness and improving the service life of the wire harness.

[0170] It can be understood that for the above-mentioned Embodiments 1-9, except for the parts in conflict, they can be freely combined to form other embodiments of the present invention.

[0171] In the description of the present invention, it should be understood that the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.
