Background Art

The sorting unit is a logistics sorting equipment. The execution device of the sorting unit is the first sorting platform. The first sorting platform is often set to be electrically driven, which includes a motor, two rollers and a belt provided 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 will be easily damaged after a long time of running, making it difficult to reduce the maintenance frequency of the first sorting platform, and also reducing the express sorting efficiency;

Therefore, when the sorting unit is running, the operation of the sorting platform can be controlled by the mechanical structure in conjunction with the clutch device. However, the clutch device is often set in an exposed form. The express delivery falling on the sorting platform and the impact received by the sorting unit during operation are at risk of damaging the clutch device. After the clutch device is damaged, the sorting platform will immediately fail, and the staff cannot shut it down for maintenance, which reduces the express sorting efficiency.

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 bag platform and the lower bag grid, and further affect the utilization rate of the site where the sorting unit is located.

DETAILED DESCRIPTION

In order to better explain the present invention and facilitate understanding, the present invention is described in detail below in conjunction with Figures 1 to 10 through specific implementations. Wherein, the directional terms such as "upper" and "lower" mentioned herein are based on the orientation of Figure 4.

Embodiment 1:

1 to 5 , an embodiment of the present invention provides a sorting unit I, which 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, and 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, 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 unit I also includes a first rotating shaft 4, which 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, and the axis of the first rotating shaft 4 extends along the width direction of the sorting unit I.

The length direction is the X direction in FIG. 1 , the width direction is the Y direction in FIG. 1 , and the height direction is the Z direction in FIG. 1 .

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 and will not affect the normal operation of the first clutch device 2;

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 will not affect the height layout of the frame 1 .

At the same time, one side opening of the first assembly cavity 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 first assembly cavity A and the first clutch device 2 are provided, resulting in an increase in the size of the frame 1 along the width direction of the sorting unit I, it will not protrude from the vertical projection contour of the first sorting platform 3. Therefore, the first clutch device 2 will not affect the overall layout of the sorting unit I.

Since the first assembly cavity A is entirely embedded in the outline of the frame 1, the sorting unit I is cleverly used 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 beneficial 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.

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 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 blocks the top opening of the frame to form a first assembly cavity A, and the first rotating shaft 4 is rotatably connected to the main frame body 101.

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, and the top of the frame is blocked by the first sorting platform 3 to form a first assembly cavity A. In this way, the first assembly cavity A can be formed. In this case, the frame 1 does not have any additional unnecessary components, which is beneficial to reducing the curb weight of the frame 1, and further beneficial to achieving the lightweight of the sorting unit I.

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.

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.

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.

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.

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.

The second shaft 6 can be configured to be rotatably connected to the second connecting member 103, and the first clutch device 2 is used to disconnect or combine the driving connection relationship between the first shaft 4 and the second shaft 6. When the first clutch device 2 is switched to the closed state, the second shaft 6 can be linked with the first shaft 4 to drive the first sorting platform 3 to operate; when the first clutch device 2 is switched to the disconnected state, the torque transmission between the second shaft 6 and the first shaft 4 is disconnected, and the first sorting platform 3 will stop. Stop operation.

The second rotating shaft 6 is rotatably connected to the frame 1, and the second rotating shaft 6 maintains a driving connection with 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, thereby making the first sorting platform 3 operate or stop operating.

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.

The sorting unit I further comprises casters 15 , which are vertically hinged to the frame 1 , and the casters 15 are capable of supporting the frame 1 .

In this embodiment, sorting unit I can be supported not only by the first driving wheel 5, but also by the caster 15. The two can be arranged to play a supporting role at the same time, or it can be arranged that in the sorting interval of sorting unit I, sorting unit I is supported by the first driving wheel 5, and in the non-sorting interval of sorting unit I, sorting unit I is supported by the caster 15.

In the present embodiment, the caster 15 is configured to be vertically rotatable in order to make the caster 15 match the turning condition of the sorting unit I. In most cases, when the sorting unit I has a sorting demand, the sorting unit I runs in a straight line. Therefore, when the sorting unit I has an operation demand, the sorting unit I is supported by the first driving wheel 5, and when the sorting unit I has no operation demand, the sorting unit I is supported by the caster 15. This can reduce the wear of the first driving wheel 5 and increase the service life of the first driving wheel 5.

Specifically, the first driving wheel 5 and the caster 15 are both configured as rubber-coated wheels.

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

By providing 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.

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, so that the sorting unit I has better flexibility in use.

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 installation requirements of the sleeve 14. This can reduce the overall cost of the sorting unit I.

Specifically, when the third rotating shaft 9 adopts the arrangement form in Example 3, the two sleeves 14 are both installed on the main frame.

When the third rotating shaft 9 adopts the arrangement form in Example 4, 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.

Embodiment 6:

9 and 10 , the embodiment of the present invention provides a sorting and transport line including 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 improve the express sorting efficiency.

Line body II forms a horizontal closed loop, and multiple 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; multiple sorting assemblies are hinged end to end along the vertical axis and then run along line body II.

In this technical solution, the sorting planes of the sorting unit 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, so that the sorting assembly can be used to transport large express deliveries, thereby improving the adaptability of the sorting and transportation line to the express size.

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

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 track 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.

In a technical solution of the present invention, the sorting and transporting line further includes a linear motor device, which includes a moving part B and a fixed part, wherein the fixed part is arranged on the line body II; and the moving part B is arranged on the frame 1.

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 body 101. The control system is arranged in the storage cavity to further improve the structural compactness of the sorting unit I.

The front and rear sides of the frame 1 are provided with connection holes 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 passing the wiring harness, which are used to arrange the wiring harness. This wiring harness arrangement form 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.
