Description

Technical Field

[0001] This invention relates to the technical field of express delivery sorting, and more particularly to an express delivery sorting track system. Background Technology

[0002] In the field of express sorting, express sorting operations can be completed by using a production line and a continuous express sorting vehicle line running on the production line while the express sorting vehicles are in operation.

[0003] The express sorting line includes multiple express sorting vehicles connected end to end. Each express sorting vehicle includes a sorting platform for sorting express packages and a mechanism for driving the sorting platform. The mechanism can be configured as a purely mechanical structure and includes actuating components. The mechanism is connected to the sorting platform drive.

[0004] Along the width direction of the line, the actuating element can switch between the inner limit position, the inner area position, the centering position, the outer area position, and the outer limit position. The actuating elements corresponding to the inner limit position and the outer limit position are located in the inner area position and the outer area position in the width direction of the line. The inner area position is located between the centering position and the inner limit position, and the outer area position is located between the centering position and the outer limit position.

[0005] When the actuating component moves along the width of the line, that is, when switching between the above-mentioned positions, the mechanism will output driving torque to the sorting platform to drive the sorting platform to operate.

[0006] After the express sorting vehicle performs express sorting operations, the corresponding moving parts will move to the inner or outer limit position. In order to enable it to perform express sorting again, it needs to be reset to the center position. However, when the track is centered and the loading platform and the sorting platform are often flush, after the loading platform distributes the express to the corresponding sorting platform, the express will be located on one side of the sorting platform. If the express is kept on one side of the sorting platform for express sorting operations, the sorting platform will not have enough stroke to sort the express to the other side of the sorting platform, making it difficult for the express sorting vehicle to achieve bidirectional sorting. Summary of the Invention

[0007] (a) Technical problems to be solved

[0008] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a courier sorting track system to solve the technical problem that if the courier is kept on one side of the sorting platform for sorting operations, the sorting platform will lack sufficient travel to sort the courier to the other side of the sorting platform, making it difficult for the courier sorting vehicle to achieve bidirectional sorting.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0011] In a first aspect, the present invention provides an express sorting track system, comprising a line and a toggle member, characterized in that: the toggle member can switch between an inner limit position, an inner region position, a centering position, an outer region position, and an outer limit position; it also includes a sorting closed loop, the sorting closed loop including a reset track device and an upper packing track device; the reset track device can switch the toggle member to the inner region position; the upper packing track device includes an upper packing track unit, the upper packing track unit including an inner guide track and an inner rail guide member, the inner guide track having an inner rail break zone, the inner rail guide member being disposed in the inner rail break zone; the inner rail guide member can switch between an inner rail change position and an inner rail compensation position; the toggle member can run along the length direction of the line; when the inner rail guide member is in the inner rail change position, the toggle member in the inner limit position can be guided by the inner rail guide member to the inner rail break zone, and enter the inner region position through the inner rail break zone; when the inner rail guide member is in the inner rail compensation position, the toggle member in the inner limit position can maintain the inner limit position.

[0012] In this technical solution, the reset track device can switch the actuating component to the inner limit position, that is, it can make the actuating component and the mechanism move to one side of the express sorting vehicle. At this time, when the mechanism is performing the loading operation, the actuating component and the mechanism can move to the inner area position, thereby enabling the sorting platform to drive the express from one side of the sorting platform to the middle of the sorting platform, so as to ensure that the position of the express is always close to the middle position of the sorting platform, thereby ensuring that the express sorting vehicle can achieve bidirectional sorting when performing express sorting operations.

[0013] The packing track device includes a track unit. The inner guide track of the packing track unit receives the reset track device. When there is a packing requirement on the express sorting vehicle, the inner guide can switch to the inner track changing position. At this time, the agitator running along the inner guide track will be guided by the inner guide to enter the inner area. This process corresponds to the packing process, that is, the express will move from one side of the sorting platform to the middle of the sorting platform.

[0014] When there is no need to load packages onto the express sorting vehicle, that is, when there is no need to load packages onto the corresponding loading device, the inner rail guide will switch to the inner rail compensation position, so that the actuating part is kept in the inner limit position.

[0015] In one technical solution of the present invention, the inner guide rail extends along the length direction of the line body; multiple upper rail units are arranged sequentially along the length direction of the line body.

[0016] In this technical solution, multiple consecutive packing track units are set up, so that the sorting track system has multiple adjacent packing slots. Each packing slot corresponds to a packing platform, and each packing platform can transport express packages to the sorting platform. The corresponding packing platform only operates when the express sorting vehicle has a packing demand. When the express sorting vehicle runs to the packing track unit corresponding to the packing platform, the inner rail guide in the packing track unit will switch to the inner rail changing position, so that the express package output to the sorting platform will move closer to the center of the sorting platform.

[0017] When there is no need to load a package at the corresponding compartment of the express sorting platform, the inner rail guide in the loading track unit corresponding to the loading platform in that compartment will switch to the inner rail compensation position so that the actuating part and the mechanism are kept in the inner limit position. Only when there is a need to load a package for the express sorting vehicle will the corresponding inner rail guide in the corresponding loading track unit be controlled to switch to the inner rail change position.

[0018] As can be seen, by adopting the technical solution in this invention, each express sorting vehicle can independently load packages without affecting each other, which greatly improves the loading efficiency.

[0019] In one technical solution of the present invention, the sorting closed loop further includes a sorting track device, a reset track device and a collection track device arranged sequentially on the line, with the upper packing track device located between the reset track device and the collection track device.

[0020] In this technical solution, by setting up the various track devices in the above order, it is possible to ensure the continuity of express sorting and loading operations while ensuring the closed-loop sorting process.

[0021] In one technical solution of the present invention, the sorting track device enables the agitator to move from the center position to the inner limit position or the outer limit position; the packing track device enables the agitator to move from the inner limit position to the inner area position; and the collecting track device enables the agitator to move from the inner area position to the center position.

[0022] In this technical solution, the process of the sorting track device moving the toggle piece from the center position to the inner limit position or the outer limit position corresponds to the express delivery sorting process. The process of the packing track device moving the toggle piece from the inner limit position to the inner area position corresponds to the express delivery packing process. After the gathering track device moves the toggle piece from the inner area position to the center position, the express delivery on the sorting platform moves to the center of the sorting platform as the sorting platform runs.

[0023] In one technical solution of the present invention, the track reset device includes an outer guide rail and an outer rail guide member. The outer guide rail has an outer rail break area, and the outer rail guide member is disposed in the outer rail break area. The outer rail guide member can switch between an outer rail compensation position and an outer rail change position.

[0024] When the outer rail guide maintains the outer rail compensation position, the actuating component in the centering position can be guided to the inner limit position by the outer rail guide and the outer guide rail; when the outer rail guide maintains the outer rail change position, the actuating component in the centering position passes through the outer rail disconnection zone.

[0025] The actuating element in the outer limit position, outer region position, and inner region position can be guided by the outer guide rail to the inner limit position, and the actuating element in the inner limit position remains in the inner limit position.

[0026] The inner guide rail in the upper rail unit near the outer rail device is connected to the outer guide rail.

[0027] In this technical solution, after the express sorting vehicle runs to the reset track device, the actuating parts of the core of the express sorting vehicle that participated in the sorting will run to the inner limit position, the inner area position, the outer area position, or the outer limit position. The actuating parts in the above four positions will always be moved to the inner limit position by the outer guide rail, ensuring that the express sorting vehicle has sufficient adjustment stroke when running to the packing track device to ensure that the express after packing is in the middle position of the sorting platform.

[0028] The actuating parts of the mechanism of the express sorting cart that is not involved in sorting will also be actuated to the inner limit position when the outer rail guide is in the outer rail compensation position. This working condition corresponds to the working condition where the sorting platform of the express sorting cart has the need to load packages.

[0029] When the outer rail guide is in the outer rail change position, the actuating component of the mechanism of the express sorting cart that is not involved in sorting will pass directly through the outer rail break zone and remain in the center position. This working condition corresponds to the working condition where the sorting platform of the express sorting cart does not have the need for loading or sorting.

[0030] Therefore, the reset track device can flexibly match the actual needs of the packing track device and the sorting track device, greatly improving the flexibility of the express sorting track system and also improving the express sorting efficiency.

[0031] In one technical solution of the present invention, when the outer rail guide is in the change of track position, the actuating member in the outer limit position or the outer region position, after contacting the outer guide rail, crosses the outer rail break zone under the action of inertia.

[0032] In this technical solution, the inertia of the actuating component running along the outer guide rail is used to enable it to cross the outer rail break zone. Thus, regardless of the position of the outer rail guide component, as long as the position of the actuating component is not the center position, the actuating component will be moved to the inner limit position. This reduces the control cost of the outer rail guide component and improves the reliability of the reset rail device.

[0033] The outer guide rail includes a first section and a second section. An outer rail break zone is formed between the near ends of the first and second sections. The second section is closer to the upper rail device than the first section. There is a step difference along the length of the line between the near ends of the second and first sections.

[0034] In this technical solution, the outer guide rail includes a first section and a second section. By creating a step difference between the first section and the second section along the length of the line, it can be further ensured that the actuating component at the outer limit position and the outer area position can cross the outer rail break zone when running along the length of the line, thus avoiding interference between the actuating component and the outer rail break zone, and also improving the smoothness of the actuating component sliding along the outer guide rail.

[0035] In one technical solution of the present invention, the resetting track device further includes an inner centering track, one end of which is connected to the first end of the outer guide track, and the inner centering track extends along the length direction of the line.

[0036] In this technical solution, by setting an additional inner centering rail, the position of the actuating component passing through the outer rail break zone along the width direction of the line can be restricted, thereby improving the stability of the actuating component of the express sorting vehicle's mechanism when running along the length direction of the line.

[0037] In one embodiment of the present invention, the upper track unit further includes an outer centering track extending along the length of the track.

[0038] In this technical solution, when the inner rail guide is in the inner rail changing position, the inner rail guide guides the actuating component into the inner area. Since the actuating component will still have inertia, the outer centering rail can block the actuating component that will move inertia, so as to avoid it running in the outer area.

[0039] In one technical solution of the present invention, the collecting track device includes an outer connecting track and an inner connecting track, and a collecting channel is formed between the outer connecting track and the inner connecting track. The collecting channel extends along the length direction of the line body, one end of the collecting channel is a first end that receives the upper packaging track device, and the other end of the collecting channel is a second end that receives the sorting track device.

[0040] In this technical solution, the converging channel formed between the outer connecting track and the inner connecting track can restrict the position of the actuating component along the width direction of the line. As the express sorting vehicle runs, the actuating component corresponding to the inner area position will be moved to the center position, thereby ensuring the normal operation of express sorting.

[0041] In one technical solution of the present invention, the opening of the collection channel gradually decreases from the first end of the collection channel to the second end of the collection channel.

[0042] In this technical solution, the converging channel is set in the shape of a trumpet, and both the outer and inner connecting rails are arc-shaped. When the toggle component runs along the length of the line, it will gradually move from the inner area to the center position. The whole process is gentle and produces almost no collision noise, which helps to improve the quietness of the process and also increases the service life of the toggle component, the outer connecting rail, and the inner connecting rail.

[0043] In one technical solution of the present invention, the sorting closed loop is configured as multiple nested loops.

[0044] In this technical solution, multiple sorting closed loops also correspond to multiple continuous express sorting lines, which can enable multiple express sorting lines to operate together to improve express sorting efficiency.

[0045] (III) Beneficial Effects

[0046] The beneficial effects of the present invention are as follows: The express sorting track system of the present invention has a track reset device that enables the actuating component to switch to the inner limit position, that is, enables the actuating component and the mechanism to move to one side of the express sorting vehicle. At this time, when the mechanism is performing the loading operation, the actuating component and the mechanism can move to the inner area position, thereby enabling the sorting platform to drive the express from one side of the sorting platform to the middle of the sorting platform, so as to ensure that the position of the express is always close to the middle position of the sorting platform, thereby ensuring that the express sorting vehicle can achieve bidirectional sorting when performing express sorting operations.

[0047] The packing track device includes a track unit. The inner guide track of the packing track unit receives the reset track device. When there is a packing requirement on the express sorting vehicle, the inner guide can switch to the inner track changing position. At this time, the agitator running along the inner guide track will be guided by the inner guide to enter the inner area. This process corresponds to the packing process, that is, the express will move from one side of the sorting platform to the middle of the sorting platform.

[0048] When there is no need to load packages onto the express sorting vehicle, that is, when there is no need to load packages onto the corresponding loading device, the inner rail guide will switch to the inner rail compensation position, so that the actuating part is kept in the inner limit position.

[0049] In this way, it can be ensured that when the express sorting vehicle is carrying out express sorting operations, the sorting platform has sufficient travel distance to drive the express delivery, ensuring that it can achieve two-way sorting. Attached Figure Description

[0074] To better explain and facilitate understanding of this invention, the following description is provided in conjunction with the appendix. Figure 1-15 The present invention will be described in detail through specific embodiments. In this document, directional terms such as "upper" and "lower" are used interchangeably with other directional terms. Figure 4 The orientation is used as a reference.

[0075] Example 1:

[0076] Reference Figure 1-15An embodiment of the present invention provides a parcel sorting track system, including a line body 1 and a toggle member 2, the toggle member 2 being switchable between an inner limit position A, an inner area position B, a centering position C, an outer area position D, and an outer limit position E; it also includes a sorting closed loop, the sorting closed loop including a reset track device 4 and a packing track device 5; the reset track device 4 enables the toggle member 2 to switch to the inner area position B; the packing track device 5 includes a packing track unit 51, the packing track unit 51 including an inner guide track 511 and an inner rail guide member 512, the inner guide track 511 having... There is an inner rail break zone J, and an inner rail guide 512 is located in the inner rail break zone J. The inner rail guide 512 can switch between the inner rail change position K and the inner rail compensation position L. The actuating member 2 can run along the length direction of the line body 1. When the inner rail guide 512 is in the inner rail change position K, the actuating member 2, which is in the inner limit position A, can be guided by the inner rail guide 512 to the inner rail break zone J and enter the inner area position B through the inner rail break zone J. When the inner rail guide 512 is in the inner rail compensation position L, the actuating member 2, which is in the inner limit position A, can maintain the inner limit position A.

[0077] The mechanism includes a sliding component and a transmission component. The sliding component is slidably connected to the frame of the express sorting vehicle along the width direction of the line. The transmission component is located on the frame, and the actuating component is connected to the sliding component. The sliding component is used to bear the load along the width direction of the frame to drive the transmission component to run, thereby driving the sorting platform to operate.

[0078] More specifically, the transmission component includes a first transmission assembly, which is driven to connect to the sorting platform; the first transmission assembly includes a first chain and two first sprockets that cooperate with each other, both first sprockets are rotatably connected to the frame, a sliding member is connected to the first chain, and one first sprocket is driven to connect to the torque input end of the sorting platform.

[0079] The transmission component also includes a second transmission component that establishes a linkage between the first transmission component and the sorting platform. The second transmission component includes a cooperating second chain and two second sprockets. One second sprocket is connected to the first sprocket, and the other second sprocket is connected to the torque input end of the sorting platform.

[0080] In this embodiment, the reset track device 4 can switch the actuating member 2 to the inner limit position A, that is, it can make the actuating member 2 and the mechanism move to one side of the express sorting vehicle. At this time, when the mechanism is performing the packing operation, the actuating member 2 and the mechanism can move to the inner area position B, thereby enabling the sorting platform to drive the express from one side of the sorting platform to the middle of the sorting platform, so as to ensure that the position of the express is always close to the middle position of the sorting platform, thereby ensuring that the express sorting vehicle can achieve bidirectional sorting when performing express sorting operations.

[0081] The packing track device 5 includes a track unit. The inner guide track 511 of the packing track unit 51 receives the reset track device 4. When there is a packing requirement for the express sorting vehicle, the inner rail guide 512 can switch to the inner rail change position K. At this time, the toggle 2 running along the inner guide track 511 will be guided by the inner rail guide 512 and enter the inner area position B. This process corresponds to the packing process, that is, the express will move from one side of the sorting platform to the middle of the sorting platform.

[0082] When there is no need to load packages on the express sorting vehicle, that is, when there is no need to load packages at the corresponding loading device, the inner rail guide 512 will switch to the inner rail compensation position L, so that the actuating part 2 is kept in the inner limit position A.

[0083] Specifically, line 1 is a loop, and the loading and sorting positions of the express sorting vehicle can be set as straight segments of the loop to facilitate loading and sorting operations.

[0084] like Figure 4-6 In this embodiment, the inner guide rail 511 extends along the length direction of the line body 1; multiple upper rail units 51 are arranged sequentially along the length direction of the line body 1.

[0085] In this embodiment, multiple packing track units 51 are arranged in succession, so that the sorting track 312 system has multiple adjacent packing slots. Each packing slot corresponds to a packing platform, and each packing platform can deliver express packages to the sorting platform. The corresponding packing platform only operates when the express sorting vehicle has a packing requirement. When the express sorting vehicle runs to the packing track unit 51 corresponding to the packing platform, the inner rail guide 512 in the packing track unit 51 will switch to the inner rail changing position K, so that after the express package is output to the sorting platform, it will move closer to the center of the sorting platform.

[0086] When there is no need to load a package at the corresponding slot of the express sorting platform, the inner rail guide 512 in the loading track unit 51 corresponding to the loading platform in that slot will switch to the inner rail compensation position L, so that the actuating part 2 and the mechanism are kept in the inner limit position A. Only when there is a need to load a package for the express sorting vehicle will the corresponding inner rail guide 512 in the corresponding loading track unit 51 be controlled to switch to the inner rail change position K.

[0087] As can be seen, by adopting the technical solution in this invention, each express sorting vehicle can independently load packages without affecting each other, which greatly improves the loading efficiency.

[0088] like Figure 9 , Figure 12 and Figure 13As shown, in this embodiment, the reset track device 4 further includes an inner centering track 43, one end of which is connected to the first end of the outer guide track 41, and the inner centering track 43 extends along the length direction of the line body 1.

[0089] In this embodiment, by additionally setting the inner centering track 43, the position of the actuating element 2 passing through the outer track disconnection zone I along the width direction of the line body 1 can be restricted, thereby improving the stability of the actuating element 2 of the express sorting vehicle's mechanism when running along the length direction of the line body 1.

[0090] like Figure 4-6 In this embodiment, the sorting closed loop also includes a sorting track device 3, a reset track device 4 and a collection track device 6 arranged sequentially on the line 1, with the upper pack track device 5 located between the reset track device 4 and the collection track device 6.

[0091] In this embodiment, by arranging the various track devices in the above order, it is possible to ensure the continuity of express sorting and express loading operations while ensuring the closed-loop sorting is completed.

[0092] like Figure 4-15 In this embodiment, the sorting track device 3 enables the agitator 2 to move from the centering position C to the inner limit position A or the outer limit position E; the packing track device 5 enables the agitator 2 to move from the inner limit position A to the inner area position B; and the collecting track device 6 enables the agitator 2 to move from the inner area position B to the centering position C.

[0093] In this embodiment, the process of the sorting track device 3 causing the actuating element 2 to move from the centering position C to the inner limit position A or the outer limit position E corresponds to the express delivery sorting process. The process of the packing track device 5 causing the actuating element 2 to move from the inner limit position A to the inner area position B corresponds to the express delivery packing process. After the gathering track device 6 causes the actuating element 2 to move from the inner area position B to the centering position C, the express delivery on the sorting platform moves to the center of the sorting platform as the sorting platform runs.

[0094] like Figure 9 , Figure 12 and Figure 13In this embodiment, the reset track device 4 includes an outer guide track 41 and an outer rail guide member 42. The outer guide track 41 has an outer rail break zone I, and the outer rail guide member 42 is located in the outer rail break zone I. The outer rail guide member 42 can switch between the outer rail compensation position Q and the outer rail change position R. When the outer rail guide member 42 maintains the outer rail compensation position Q, the actuating member 2 in the centering position C can be guided by the outer rail guide member 42 and the outer guide track 41 to the inner limit position A. When the outer rail guide member 42 maintains the outer rail change position R, the actuating member 2 in the centering position C passes through the outer rail break zone I. The actuating member 2 in the outer limit position E, the outer region position D, and the inner region position B can be guided by the outer guide track 41 to the inner limit position A, and the actuating member 2 in the inner limit position A maintains the inner limit position A. The inner guide track 511 in the upper wrapping track unit 51 near the outer track device is supported by the outer guide track 41.

[0095] In this embodiment, after the express sorting vehicle runs to the reset track device 4, the actuating component 2 of the core of the express sorting vehicle that participated in the sorting will run to the inner limit position A, the inner area position B, the outer area position D, or the outer limit position E. The actuating component 2 in the above four positions will always be actuated to the inner limit position A by the outer guide track 41, ensuring that the express sorting vehicle has sufficient adjustment stroke when running to the packing track device 5 to ensure that the express after packing is in the middle position of the sorting platform.

[0096] The actuating component 2 of the mechanism of the express sorting cart that is not involved in sorting will also be actuated to the inner limit position A when the outer rail guide component 42 is in the outer rail compensation position Q. This working condition corresponds to the working condition where the sorting platform of the express sorting cart has the need to load packages.

[0097] When the outer rail guide 42 is in the outer rail change position R, the actuating component 2 of the mechanism of the express sorting cart that is not involved in sorting will pass directly through the outer rail disconnection area I and remain in the center position C. This working condition corresponds to the working condition where the sorting platform of the express sorting cart has no packing or sorting requirements.

[0098] Therefore, the reset track device 4 can flexibly match the actual needs of the packing track device 5 and the sorting track device 3, greatly improving the flexibility of the express sorting track system and also improving the express sorting efficiency.

[0099] like Figure 7 and Figure 8 The sorting track device 3 includes multiple sorting track units 31 arranged along the length direction of the line body 1. The sorting track units 31 are configured as two symmetrically arranged along the length direction of the line body 1 to realize bidirectional sorting of express delivery.

[0100] Sorting track unit 31 includes main track 311, sorting track 312 and main track guide 313. The main track 311 has a main track break area P and the main track guide 313 is located in the main track break area P.

[0101] One end of the sorting track 312 is the first end adjacent to the main track break area P, and the other end of the sorting track 312 is the second end extending away from the corresponding main track 311 along the width direction of the line body 1. The second end of the sorting track extends inclined along the running direction of the express sorting vehicle on the line body 1.

[0102] The main rail guide 313 can switch between the main rail compensation position F and the main rail changing position G;

[0103] When the main rail guide 313 maintains the main rail compensation position F, the actuating member 2, which is in the centering position C, can maintain its movement along the extension direction of the main rail 311 and maintain the centering position C.

[0104] When the main rail guide 313 maintains the main rail changing position G, the agitator 2, which is in the centering position C, can be guided by the main rail guide 313 to the sorting track 312, so that the sorting track 312 can guide the agitator 2 from the centering position C to the inner limit position A or the outer limit position E.

[0105] A main rail channel H is formed between the two main rails 311 in the two sorting rail units 31. The position of the main rail channel H along the width direction of the line body 1 corresponds to the centering position C of the actuating member 2, and the main rail channel H extends to the reset rail device 4.

[0106] The sorting track device 3 and the reset track device 4 may also be additionally equipped with retaining tracks, including a first retaining track and a second retaining track. The first retaining track forms a first retaining channel that connects to the main track channel 311 at one end and to the centering position C at the other end. The second track forms a second retaining channel that connects to the inner limit position A of the sorting track device 3 at one end and to the inner limit position A of the centering track device at the other end. The first retaining channel and the second retaining channel are used to further limit the position of the actuating lever 2 and prevent the actuating lever 2 from sliding when it runs along the line body 1 through the position between the sorting track device 3 and the reset track device 4.

[0107] Specifically, one end of the main rail guide 313, the outer rail guide 42, and the inner rail guide 512 can be hinged to the line body 1, and all of them are set as levers. The swing is controlled by the cylinder on the line body 1, that is, the main rail guide 313, the outer rail guide 42, and the inner rail guide 512 can all swing to the corresponding compensation position and track change position.

[0108] The cylinder is controlled by a control device, which can identify the code of each express sorting vehicle and make individual adjustments to each vehicle.

[0109] Specifically, the control device can be set as a PLC.

[0110] like Figure 13 In this embodiment, when the outer rail guide 42 is in the changing position, the actuating member 2, which is in the outer limit position E and the outer region position D, crosses the outer rail disconnection zone I under the action of inertia after contacting the outer guide rail 41.

[0111] In this embodiment, the inertia of the toggle member 2 as it runs along the outer guide rail 41 is used to enable it to cross the outer rail disconnection zone I. Thus, regardless of the position of the outer rail guide member 42, as long as the position of the toggle member 2 is not the center position C, the toggle member 2 will be toggleed to the inner limit position A. This reduces the control cost of the outer rail guide member 42 and improves the reliability of the reset rail device 4.

[0112] like Figure 9 , Figure 12 and Figure 13 The outer guide rail 41 includes a first section and a second section. An outer rail break zone I is formed between the close ends of the first section and the second section. The second section is closer to the upper rail device 5 than the first section. There is a step difference along the length direction of the line body 1 between the close ends of the second section and the first section.

[0113] In this embodiment, the outer guide rail 41 includes a first segment and a second segment. By creating a segment difference between the first segment and the second segment along the length direction of the line body 1, it can be further ensured that the actuating member 2, which is at the outer limit position E and the outer region position D, can cross the outer rail break zone I when running along the length direction of the line body 1, thus avoiding interference between the actuating member 2 and the outer rail break zone I, and also improving the smoothness of the actuating member 2 sliding along the outer guide rail 41.

[0114] like Figure 9 , Figure 12 and Figure 13 In this embodiment, the reset track device 4 also includes an inner centering track 43, one end of which is connected to the first end of the outer guide track 41, and the inner centering track 43 extends along the length direction of the line body 1.

[0115] In this embodiment, by additionally setting the inner centering track 43, the position of the actuating element 2 passing through the outer track disconnection zone I along the width direction of the line body 1 can be restricted, thereby improving the stability of the actuating element 2 of the express sorting vehicle's mechanism when running along the length direction of the line body 1.

[0116] like Figure 9 , Figure 12and Figure 13 In this embodiment, the upper track unit 51 further includes an outer centering track 514 extending along the length direction of the line body 1.

[0117] In this embodiment, when the inner rail guide 512 is in the inner rail changing position K, the inner rail guide 512 guides the actuating member 2 into the inner region position B. Since the actuating member 2 will still have inertia, the outer centering rail 514 can block the actuating member 2 that will run with inertia, so as to avoid it running in the outer region position D.

[0118] A first channel N is formed between the outer centering track 514 and the inner guide track 511. The position of the first channel N along the width direction of the line body 1 corresponds to the inner area position B and the centering position C of the actuating member 2. The actuating member 2 in the first channel N has two types: one is the actuating member 2 guided to the inner area position B through the centering track unit, and the other is the actuating member 2 that maintains the centering position C.

[0119] like Figure 15 In this embodiment, the collecting track device 6 includes an outer connecting track 61 and an inner connecting track 62. A collecting channel O is formed between the outer connecting track 61 and the inner connecting track 62. The collecting channel O extends along the length direction of the line body 1. One end of the collecting channel O is the first end that receives the first channel N, and the other end of the collecting channel O is the second end that receives the sorting track device 3.

[0120] In this embodiment, the converging channel O formed between the outer connecting track 61 and the inner connecting track 62 can restrict the position of the actuating member 2 along the width direction of the line body 1. As the express sorting vehicle runs, the actuating member 2, which is located in the inner area position B, will be moved to the center position C, thereby ensuring the normal operation of the express sorting work.

[0121] like Figure 15 In this embodiment, the opening of the collection channel O gradually decreases from the first end of the collection channel O to the second end of the collection channel O.

[0122] In this embodiment, the converging channel O is shaped like a trumpet, and both the outer connecting rail 61 and the inner connecting rail 62 are arc-shaped. When the toggle 2 runs along the length of the line 1, the toggle 2 will gradually move from the inner region position B to the centering position C. The whole process is gentle and almost no collision noise is generated, which helps to improve the quietness of the process and also improves the service life of the toggle 2, the outer connecting rail 61 and the inner connecting rail 62.

[0123] like Figure 4-6 In this embodiment, the sorting closed loop is configured as multiple nested loops.

[0124] In this embodiment, multiple sorting closed loops also correspond to multiple continuous express sorting lines, which can enable multiple express sorting lines to operate together to improve express sorting efficiency.
