[0002] This case claims the priority information of the utility model named "Sorting Unit and Sorting and Transportation Line" with the application date of October 24, 2023 and the application number of 202322853896.5. Background Art

[0003] The sorting unit is a logistics sorting device, and the execution device of the sorting unit is the first sorting platform. The first 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 running for a long time, making it difficult to reduce the maintenance frequency of the first sorting platform and also reducing the express sorting efficiency.

[0004] Therefore, when the sorting unit is running, the operation of the sorting platform can be controlled by a mechanical structure cooperating with a clutch device. However, the clutch device is often set in an exposed form, and there is a risk of damage to the clutch device from the express packages that fall on the sorting platform and the impacts received during the operation of the sorting unit. After the clutch device is damaged, the sorting platform immediately fails, and the staff has to stop the machine for maintenance, reducing the express sorting efficiency.

[0005] In addition, 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 table and the lower package grid, and further affect the utilization rate of the site where the sorting unit is located.

Therefore, the first clutch device will not affect the overall layout of the sorting unit.

[0032] Since the first assembly cavity is integrally embedded within the contour of the frame and the sorting unit is cleverly utilized as a component of the first assembly cavity, after the first clutch device is assembled, it will neither occupy space outward in the width direction of the sorting unit, nor in the height direction of the sorting unit, nor in the length direction of the sorting unit. Therefore, it will not make the sorting unit appear bloated, which is beneficial to improving the structural compactness and aesthetics of the sorting unit, and will not affect the upper package platform and lower package compartments of the sorting unit, and thus will not reduce the utilization rate of the site where the sorting unit is located.

[0063] For better explaining the present invention for easy understanding, the present invention will be described in detail below in conjunction with the attached Figures 1-10 , through specific implementation modes. Among them, the orientation nouns such as "up" and "down" mentioned in this article are based on the Figure 4 orientation.

[0064] Embodiment 1:

[0065] Referring to Figures 1-5 , an embodiment of the present invention provides a sorting unit Ⅰ. The sorting unit Ⅰ can run along its own length direction. The sorting unit Ⅰ includes a frame 1, a first clutch device 2 and a first sorting platform 3. The first sorting platform 3 is rotatably arranged on the frame 1; a first assembly cavity A with an open lower side is formed between the frame 1 and the first sorting platform 3. 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 unit Ⅰ further includes a 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, and the axis of the first rotating shaft 4 extends along the width direction of the sorting unit Ⅰ.

[0066] The length direction is the Figure 1 X direction in Figure 1 , the width direction is the Figure 1 Y direction in

[0067] 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;

[0068] Due to the setting of this first assembly cavity A, the first clutch device 2 can be embedded within the contour of the frame 1. Therefore, the first clutch device 2 will not affect the height layout of the frame 1.

[0069] Meanwhile, one side of the first assembly cavity A is open and is blocked by the first sorting platform 3. The first sorting platform 3 itself has a requirement for the extension length along the width direction of the sorting unit I. Therefore, even if the setting of the first assembly cavity A and the first clutch device 2 causes an increase in the size of the frame 1 along the width direction of the sorting unit I, it will not protrude beyond the vertical projection contour of the first sorting platform 3. Thus, the first clutch device 2 will not affect the overall layout of the sorting unit I.

[0070] Since the first assembly cavity A is entirely embedded within the contour of the frame 1, the sorting unit I is cleverly utilized as a component of the first assembly cavity A. After the first clutch device 2 is assembled, it will neither occupy space outward in the width direction of the sorting unit I, nor in the height direction of the sorting unit I, nor in the length direction of the sorting unit I. Therefore, it will not make the sorting unit I appear bulky, which is beneficial to improving the structural compactness and aesthetics of the sorting unit I, and will not affect the upper package platform and lower package compartments of the sorting unit I, and thus will not reduce the utilization rate of the site where the sorting unit I is located.

[0071] 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. Both the first connecting member 102 and the third connecting member 104 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 connecting member 102, the second connecting member 103, the third connecting member 104, and the main frame body 101 form a framework. The first sorting platform 3 blocks the top opening of the framework to form the first assembly cavity A. The first rotating shaft 4 is rotatably connected to the main frame body 101.

[0072] In this embodiment, the first connecting member 102, the second connecting member 103, the third connecting member 104, and the main frame body 101 jointly form a structure similar to a framework. After the top of the framework is blocked by the first sorting platform 3 to form the first assembly cavity A, this setting can, on the premise of forming the first assembly cavity A, ensure that the frame 1 has no additional unnecessary components, which is beneficial to reducing the overall mass of the frame 1, and thus beneficial to realizing the lightweight of the sorting unit I.

[0073] 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 rods form a side wall of the first assembly cavity A.

[0074] In this embodiment, the sorting unit I also includes a first driving wheel 5 connected to both ends of the first rotating shaft 4, and a second rotating shaft 6 rotatably connected to the frame 1 and 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 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.

[0075] 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 running. 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 will be 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.

[0076] The support portion 22 is supported on the frame 1, such as supported on the second connecting member 103. A groove body can be opened on the plate-shaped second connecting member 103 so that the support portion 22 is connected to the groove body.

[0077] 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 and reducing the overall cost of the sorting unit I.

[0078] 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 combine the driving connection relationship between the first rotating shaft 4 and the second rotating shaft 6. When the first clutch device 2 is switched to a closed state, the second rotating shaft 6 can be operated in conjunction with the first rotating shaft 4, and then the first sorting platform 3 can be driven to operate through the second rotating shaft 6; when the first clutch device 2 is switched to a 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.

[0079] The second rotating shaft 6 is rotatably connected to the frame 1, and the second rotating shaft 6 is drivingly connected to the first sorting platform 3; the first clutch device 2 can switch between a combined state in which a driving connection relationship between the first rotating shaft 4 and the second rotating shaft 6 is established and a separated state in which the driving connection relationship between the first rotating shaft 4 and the second rotating shaft 6 is disconnected, so as to make the first sorting platform 3 operate or stop operating.

[0080] 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.

[0081] The sorting unit I further includes a caster 15, and the caster 15 is vertically hinged to the frame 1, and the caster 15 can support the frame 1.

[0082] In this embodiment, the sorting unit I can be supported not only by the first driving wheel 5, but also by the caster 15. The two can be set to support simultaneously, or can be set to support the sorting unit I by the first driving wheel 5 in the sorting area of the sorting unit I and support the sorting unit I by the caster 15 in the non-sorting area of the sorting unit I.

[0083] In this embodiment, the caster 15 is set to be vertically rotatable in order to match the turning working condition of the sorting unit I. In most cases, when there is a sorting requirement for the sorting unit I, the sorting unit I runs in a straight line. Therefore, when the sorting unit I has an operating requirement, the sorting unit I is supported by the first driving wheel 5, and when the sorting unit I has no operating requirement, the sorting unit I is supported by the caster 15. This form can reduce the wear of the first driving wheel 5 and improve the service life of the first driving wheel 5.

[0084] Specifically, both the first driving wheel 5 and the caster 15 are set as rubber-coated wheels.

[0085] More specifically, the first driving wheel 5 can be set as a polylactone rubber-coated wheel, and the caster 15 can be set as a polyurethane rubber-coated wheel.

[0086] Embodiment 2:

[0087] Refer to Figure 6 、 Figure 7 and Figure 8 In addition to having all the technical solutions of the above embodiments, the embodiments of the present utility model further have the following technical solutions:

[0088] 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 away from the first rotating shaft 4 than the first sorting platform 3.

[0089] 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.

[0090] 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.

[0091] By setting an additional second sorting platform 7, the sorting efficiency of the sorting unit I can be doubled, and the sorting cost of express deliveries can be reduced.

[0092] 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.

[0093] The sorting unit I further includes a third rotating shaft 9 and a fourth rotating shaft 10 that are 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.

[0094] 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 generality between parts are both 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.

[0095] The second rotating shaft 6 and the fourth rotating shaft 10 are respectively arranged at two 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 arranged in two groups corresponding to the second rotating shaft 6 and the fourth rotating shaft 10.

[0096] 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 arranged 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.

[0097] 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.

[0098] 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 in reverse.

[0099] 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 in reverse.

[0100] 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.

[0101] The two ends of the first rotating shaft 4 and the third rotating shaft 9 are correspondingly provided with the first clutch device 2 and the second clutch device 11. 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.

[0102] 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 then the two first clutch devices 2 can control the first sorting platform 3 to rotate forward or in reverse.

[0103] 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 make the torque be transmitted 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.

[0104] 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 reversal.

[0105] The bevel gear transmission component can be set as an arc tooth gear to improve the stability of torque transmission.

[0106] 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.

[0107] 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 as in Figure 3 .

[0108] 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 arranged on the frame 1, or an electrical connection relationship with an external power grid can be established through carbon brushes and powered by the external power grid.

[0109] 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.

[0111] In addition to all the technical solutions of the above Embodiment 2, the embodiment of the present utility model further has the following technical solutions:

[0112] 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 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 driving wheel, 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 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.

[0113] 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 the initial torque in the same form as the first rotating shaft 4, and the third rotating shaft 9 can also be used as the support shaft of the frame 1. The second driving wheels can be frictionally rotated when the sorting unit I is operating.

[0114] Specifically, the second driving wheel has the same structure as the first driving wheel 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 operate by friction with a plane. Moreover, the second driving 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.

[0115] 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, and the symmetric axis is the midline in the length direction of the main frame 101. The second assembly cavity and the first assembly cavity A share a main frame to form one side wall of the cavity, and the drawings will not be elaborated here.

[0116] Embodiment 4:

[0117] Referring to Figure 6 、 Figure 7 and Figure 8 In addition to having all the technical solutions of the above embodiments, the second embodiment of the present invention further has the following technical solutions:

[0118] 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 drivingly connected through the third transmission device 8; the third transmission device 8 includes one of a synchronous belt transmission component, a sprocket chain transmission component, a gear transmission component, and a belt transmission component.

[0119] 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.

[0120] The third transmission device 8 includes one of a synchronous belt transmission component, a sprocket chain transmission component, a gear transmission component, and a belt transmission component to ensure the stability and reliability of the torque transmission between the first rotating shaft 4 and the third rotating shaft 9.

[0121] Specifically, in this embodiment, the first rotating shaft 4 and the third rotating shaft 9 are vertically stacked.

[0122] Embodiment 5:

[0123] Referring to Figure 1 、 Figure 5 、 Figure 6 and Figure 7 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:

[0124] The sorting unit I further includes two groups of sleeves 14. The sleeves 14 are both connected to the frame 1, and the two groups of sleeves 14 are arranged in parallel. The first rotating shaft 4 and the third rotating shaft 9 are rotatably connected within the corresponding sleeves 14.

[0125] In this embodiment, the first rotating shaft 4 and the second rotating shaft 6 are rotatably connected within the sleeve 14. During assembly, the sleeve 14 can be assembled onto 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 requirements of the sleeve 14, thereby reducing the overall cost of the sorting unit I.

[0126] Specifically, when the third rotating shaft 9 adopts the arrangement form in Embodiment 3, both of the two sleeves 14 are installed on the main frame body.

[0127] When the third rotating shaft 9 adopts the arrangement form in Embodiment 4, 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.

[0128] Embodiment 6:

[0129] Referring to Figure 9 and Figure 10 , in addition to providing a sorting and transportation line, an embodiment of the present utility model includes the sorting unit I in the above-mentioned Embodiment 2. A plurality of sorting units I are connected end to end and run along the line body II to improve the continuity of the express sorting operation and the express sorting efficiency.

[0130] The line body II forms a horizontal closed loop, and a plurality of 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; a plurality of sorting assemblies are hinged end to end along the vertical axis and run along the line body II.

[0131] In this technical solution, 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-sized express deliveries, thereby improving the adaptability of the sorting and transportation line to the size of express deliveries.

[0132] 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.

[0133] 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 wheel 5 in the sorting unit I and the track on the line body II are as consistent as possible, that is, the plane in which the first driving wheel 5 rotates is as parallel as possible to the extension plane of the length direction of the line body II.

[0134] In a technical solution of the present utility model, the sorting and transportation line further includes a linear motor device, and the linear motor device includes a moving member B and a fixed member. The fixed member is arranged on the line body II; the moving member B is arranged on the frame 1.

[0135] The frame 1 has a storage cavity capable of arranging a control system, and the storage cavity can be formed inside the main frame body 101. The control system is arranged in the storage cavity to further improve the structural compactness of the sorting unit I.

[0136] Connection holes for routing wire harnesses are provided on the front and rear sides of the frame 1, that is, wire harness ports for the wire harness to pass through are reserved on the front and rear sides of the main frame body 101 for routing the wire harness. This form of wire harness routing 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.

[0137] It can be understood that in the above Embodiments 1-5, except for the conflicting parts, they can be freely combined to form other embodiments of the present utility model.
