[0028] In order to better explain the present invention and facilitate understanding, the following Figure 1-5 , the utility model is described in detail through specific implementation methods. Among them, the directional nouns such as "upper" and "lower" mentioned in this article are Figure 1 The orientation is used as a reference.

[0029] Embodiment 1:

[0030] Reference Figure 1-Figure 4 The embodiment of the utility model provides a sorting and transporting line, comprising a plurality of sorting units connected end to end, the sorting unit comprising a frame 1, two driving devices 2 vertically stacked and connected to the frame 1, and two sorting platforms 3 vertically stacked and connected to the frame 1, the two driving devices 2 are both located below the lower sorting platform 3; it also comprises a first transmission device 4 for driving the connection between the lower driving device 2 and the lower sorting platform 3, and a second transmission device 5 for driving the connection between the upper driving device 2 and the upper sorting platform 3, the first transmission device 4 and the second transmission device 5 both make way for the position between the two sorting platforms 3; wherein the transmission route of the second transmission device 5 passes through the side of the frame 1 away from the two sorting platforms 3, and then passes through the side of the upper sorting platform 3 close to the frame 1.

[0031] In this embodiment, the two driving devices 2 and the two sorting platforms 3 are vertically stacked, which improves the sorting efficiency of the sorting unit while improving its structural compactness and reducing its horizontal space occupation, thereby helping to reduce the overall floor space of the sorting and transportation line and reduce the express sorting cost. Since the driving devices 2 are all located at the bottom of the bottom sorting platform 3, the driving devices 2 will not affect the operation of the sorting platform 3, and can also improve the overall space utilization of the sorting unit.

[0032] Specifically, the driving device 2 can be configured as a leverage driving device, and the driving device 2 includes two disconnected rotating shafts and a clutch for disconnecting or combining the linkage relationship between the two rotating shafts. The driving device 2 at the bottom also includes a driving wheel connected to one rotating shaft and capable of driving the rotating shaft to rotate. When the sorting unit moves, the driving wheel is frictionally rotated, thereby driving the rotating shaft to rotate, while the other rotating shaft is drivingly connected to the head end of the first transmission device 4. Under the control of the clutch, the torque can be selectively transmitted to the corresponding lower sorting platform 3.

[0033] The rotating shaft at one end of the driving device 2 above can be arranged in a linkage form with the driving wheel, such as a rotating shaft connected to the driving wheel below through a synchronous belt drive. The two rotating shafts of the two driving devices 2 adopt a parallel axis solution, and the other rotating shaft of the driving device 2 above is connected to the head end of the second transmission device 5. Under the control of the corresponding clutch, the torque can be selectively transmitted to the corresponding upper sorting platform 3.

[0034] The two driving devices 2 each include two driving units, that is, the lever-driven driving device is divided into two left and right groups to respectively drive the corresponding sorting platform 3 to rotate forward or reverse, and the two driving units do not provide driving force at the same time.

[0035] In this embodiment, the driving unit is used to drive the sorting platform 3 to rotate forward or reverse, so as to improve the use flexibility of the sorting platform 3.

[0036] Since the first transmission device 4 and the second transmission device 5 both make room between the two sorting platforms 3, the first transmission device 4 and the second transmission device 5 will not interfere with the express on the first sorting platform 3, thereby improving the reliability of the torque transmission process, and further improving the stability and reliability of the express sorting operation.

[0037] In addition, the transmission route of the second sorting device passes through the side of the frame 1 away from the two sorting platforms 3, and then passes through the side of the upper sorting platform 3 close to the frame 1, that is, passes through the back of the frame 1 and the upper sorting platform 3. This makes it possible for the second sorting device to occupy almost no additional space in the projection along the running direction of the sorting unit, thereby greatly improving the structural compactness of the sorting unit, and cleverly utilizing the frame 1 and the upper sorting platform 3 to shield the second transmission device 5, thereby improving the aesthetics of the sorting unit and the safety of the torque transmission process.

[0038] The frame 1 includes a base frame 11 and a vertical board 12 detachably connected to the base frame 11, the lower sorting platform 3 is supported on the base frame 11, and the upper sorting platform 3 is supported on the vertical board 12; the second transmission device 5 includes a first chain assembly 51, a second chain assembly 52 and a third chain assembly 53 which are sequentially driven and connected, the first chain assembly 51 and the third chain assembly 53 both extend horizontally, the second chain assembly 52 extends vertically, the first chain assembly 51 extends to the back of the vertical board 12, the second chain assembly 52 is located at the back of the vertical board 12, and the third chain assembly 53 is located at the back of the upper sorting platform 3.

[0039] In this embodiment, the second transmission device 5 includes a first chain assembly 51, a second chain assembly 52 and a third chain assembly 53. The three chain assemblies form a U-shaped transmission route, which can well match the shape of the vertical plate 12 and the upper sorting platform 3, thereby facilitating the hiding of the second transmission device 5.

[0040] The frame 1 includes a cover plate connected to the frame 1, and an assembly space is formed between the cover plate and the frame 1 to accommodate the first chain assembly 51 and the second chain assembly 52. ​​For example, Figure 1 As shown, the downstream of the first chain assembly 51 is located in the assembly space, the second chain assembly 52 is located in the assembly space, and the upstream of the third chain assembly 53 is located in the assembly space.

[0041] In this embodiment, the cover plate can also cover most of the first chain assembly 51 and the entire second chain assembly 52, thereby providing protection for both and ensuring the stability of the torque transmission process.

[0042] One of the vertical plate 12 and the bottom frame 11 is provided with a plurality of vertically extending waist holes, and the other is provided with connecting holes that match the waist holes one by one, and the corresponding connecting holes and the corresponding waist holes are connected by a connecting member 6. The matching design of the waist holes and the connecting holes enables the vertical plate 12 to be adjusted vertically relative to the bottom frame 11, so that the tightness of the second chain assembly 52 can be adjusted conveniently and quickly.

[0043] In this embodiment, the vertical plate 12 and the base frame 11 are detachably connected, the upper sorting platform 3 is supported on the vertical plate 12, and the lower sorting platform 3 is supported on the base frame 11. In this way, the upper sorting platform 3 and the lower sorting platform 3 can be quickly disassembled by disassembling the vertical plate 12, so that the sorting unit can quickly switch between single-layer sorting and double-layer sorting, which greatly improves the flexibility of use of the sorting unit.

[0044] The third chain assembly 53 is located between the upper sorting platform 3 and the vertical plate 12; the upper sorting platform 3 moves away from the vertical plate 12 to make room for the assembly of the third chain assembly 53. The vertical plate 12 and the upper sorting platform 3 can provide protection for the third chain assembly 53 to ensure the stability of the torque transmission process.

[0045] Arranging the third chain assembly 53 between the upper sorting platform 3 and the vertical plate 12 can save space on the back of the vertical plate 12, so that the vertical plate 12 can maintain a narrow width. The torque input end of the sorting platform 3 is arranged on both sides of the sorting platform 3. Such an arrangement can make the third chain assembly just able to be blocked by the upper sorting platform 3, further improving the structural compactness of the sorting unit.

[0046] Specifically, the two sorting platforms 3 have the same size to improve the integrity of the sorting unit parts and components and reduce procurement and assembly costs; and the running direction of the sorting platforms 3 is a vertical direction opposite to the movement of the sorting unit. The two sorting platforms 3 include two parallel rollers and a rotating belt arranged on the two rollers, and the upper plane of the rotating belt is the sorting plane of the sorting platform 3.

[0047] In this embodiment, the sorting and transporting line further includes a ring-shaped line body, and the sorting units adjacent to each other can run along the extension direction of the ring-shaped line body. The sorting and transporting line further includes a connector 6 connecting adjacent sorting units, and the connector 6 can connect the rack 1 and two sorting platforms 3 adjacent to the rack 1; wherein the connector 6 can adjust the length along the extension direction of the line body to compensate for the difference between the spacing between the lower sorting platform 3 and the adjacent rack 1 and the spacing between the upper sorting platform 3 and the adjacent rack 1. The connector 6 includes a bull's eye bearing and a connecting bolt connecting the bull's eye bearing and the corresponding sorting unit.

[0048] Since the two sorting platforms 3 have the same size and the upper sorting platform 3 is located in the gap of the third chain assembly 53, the upper sorting platform 3 will protrude more than the lower sorting platform 3. By adjusting the length of the connecting member 6 along the moving direction of the sorting unit, this difference can be compensated, so that the connection between adjacent sorting units is stable and reliable.

[0049] The sorting unit further includes a running wheel 7 , which is vertically hinged to the frame 1 . The sorting unit further includes a limiting member 8 for limiting the swing angle of the running wheel 7 , which is connected to the frame 1 .

[0050] The running wheel 7 that can swing vertically can match the curved part of the annular line, thereby improving the stability of the sorting unit when it runs on the annular line. By limiting the swing angle of the running wheel 7, it is possible to avoid the running wheel 7 from swinging too much. Therefore, when the sorting unit is assembled on the annular line, the running wheel 7 always maintains a shape within a correct range, which is conducive to the assembly of the sorting platform 3.

[0051] Specifically, the traveling wheel 7 includes a wheel body and a wheel frame, the wheel body is rotatably connected to the wheel frame, and the wheel frame is vertically hinged to the base frame 11; the limiting member 8 can be set as a bolt that is transversely threadedly connected to the base frame 11, and the end of the bolt limits the swing range of the traveling wheel 7 by squeezing the base frame 11.

[0052] In this embodiment, the sorting unit further includes two scissor plate assemblies 9 connected between the frame 1 and two sorting platforms 3 adjacent to the frame 1 to shield the gap between the frame 1 and the sorting platform 3. The scissor plate assembly 9 includes a first plate member 91 connected to the frame 1 and a second plate member 92 connected to the corresponding sorting platform 3, and the first plate member 91 and the second plate member 92 are stacked on one side thereof.

[0053] The scissor plate can fill the large gap between the rack 1 and the sorting platform 3 adjacent to the rack 1, thereby preventing the express on the sorting platform 3 from falling onto the annular line through the large gap, thereby affecting the normal progress of the express sorting operation.

[0054] Specifically, the side wall on which the first plate 91 and the second plate 92 are adjacent to each other can be configured to be an outwardly convex arc shape or polygonal shape to match the swinging requirements between adjacent sorting units.

[0055] Embodiment 2:

[0056] refer to Figure 1 In addition to all the technical features of the above-mentioned embodiment 1, this embodiment also includes the following technical solutions:

[0057] The second transmission device 5 is arranged into two groups which do not interfere with each other, and are respectively connected to the two driving units corresponding to the upper driving device 2 to drive the upper sorting platform 3 to rotate forward and reverse respectively.

[0058] In this embodiment, the second transmission device 5 is symmetrically arranged along the vertical axis of the sorting unit, and the two do not interfere with each other. They are respectively used to transmit positive torque and negative torque to the upper sorting platform 3 to ensure that the upper sorting platform 3 can operate reliably.

[0059] Embodiment 3:

[0060] refer to Figure 5 In addition to all the technical features of the above-mentioned embodiment 1, this embodiment also includes the following technical solutions:

[0061] The first chain assembly 51 and the third chain assembly 53 both include intermediate sprockets. Both ends of the first chain assembly 51 are linked to the two drive units corresponding to the upper drive device 2. The second chain assembly 52 is linked to the two intermediate sprockets, and then to the first chain assembly 51 and the third chain assembly 53.

[0062] In this embodiment, the following solution can be adopted: the first chain assembly 51 and the third chain assembly 53 are set as a long chain, and the first chain assembly 51 is linked to the torque output ends of the two drive units. Since the two drive units will not provide driving force at the same time, even if one of the drive units drives the other drive unit to operate, it will not affect the normal use of the sorting unit. The third chain assembly 53 is linked to the two torque input ends of the upper sorting platform 3, and similarly, it will not affect the normal operation of the sorting platform 3. Or the third chain assembly 53 keeps driving and connecting one torque input end of the upper sorting platform 3.

[0063] The two intermediate gears are linked by a chain to realize the linkage of the first chain assembly 51 and the third chain assembly 53, thereby ensuring reliable transmission of torque.

[0064] At the same time, a tensioning sprocket can also be provided to ensure the reliability of torque transmission.
