Description

Technical Field

[0001] This invention relates to the technical field of express delivery sorting, and more particularly to a track-changing device and an express delivery sorting and transport line. Background Technology

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

[0003] The express sorting vehicle includes a roller assembly for supporting and sorting express packages.

[0004] In the prior art, the roller assembly used as a sorting platform is often set as an electric roller. In order to drive the electric roller, a power supply module needs to be set on each express sorting vehicle. However, express sorting vehicles often need to run for a long time, and the electrical energy stored in the power supply module is insufficient to support the continuous operation of the electric roller, which causes the express sorting operation to be unable to run continuously and reduces the express sorting efficiency.

[0005] The present invention aims to propose a track-changing device and a courier sorting and transportation line, which drives the rotating roller assembly, which serves as a sorting platform, to operate through the movement of the courier sorting vehicle. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a track changing device and a courier sorting and transportation line, which solves the technical problem that when the transfer roller assembly is set as an electric roller, the electrical energy stored in the power supply module is insufficient to support the continuous operation of the electric roller, resulting in the inability of the courier sorting operation to continue and reducing the efficiency of courier sorting.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0010] In a first aspect, the present invention provides a track-changing device, comprising a track body and a main track and an auxiliary track disposed on the track body; the main track has a first sliding channel extending along the length direction of the track body; the auxiliary track has a second sliding channel extending along the length direction of the track body, one end of the second sliding channel being a first end adjacent to the first sliding channel, and the other end being a second end extending away from the first sliding channel along the width direction of the track body; wherein, the auxiliary track includes an initial state and a track-changing state, when the auxiliary track maintains the initial state, the first sliding channel remains continuous; when the auxiliary track maintains the track-changing state, the first end of the second sliding channel engages with the first sliding channel.

[0011] In this technical solution, the main track, as the primary track on the line, is fixed to the line and forms a fixed first sliding channel; the auxiliary track, on the other hand, is an auxiliary track on the line, which is movably installed on the line and can perform track-changing actions, connecting the second sliding track to the first sliding track as needed.

[0012] When the auxiliary track is in the initial state, the second sliding channel is not connected to the first sliding channel, the lever will continue to slide along the first sliding channel, the mechanism will not receive power input, the roller assembly cannot operate, and the express delivery on the roller assembly will not move relative to the roller assembly.

[0013] When the auxiliary track is in the track changing state, the second sliding channel will be inserted into the first sliding channel. When the express delivery vehicle runs along the line, the lever at the corresponding position will slide from the first sliding channel into the second sliding channel, thereby driving the lever to slide along the width of the line. At the same time, power is input to the mechanism, driving the rotating roller assembly to run and perform the express delivery sorting action, that is, throwing the express delivery off the rotating roller assembly.

[0014] Compared with existing technologies, the operation of the express sorting vehicle can be used to make the roller assembly rotate, thus making the express sorting vehicle a purely mechanical structure, which greatly improves its reliability and also helps to reduce the cost of the express sorting vehicle.

[0015] Therefore, there is no need to install electric rollers and power supply modules on the express sorting vehicle. The express sorting vehicle requires almost no maintenance during use, which improves the efficiency of express sorting. The purely mechanical express sorting vehicle also improves the safety of the express sorting process.

[0016] In one technical solution of the present invention, the main track includes two nested first tracks, forming a first sliding channel between them; the auxiliary track includes a second track and a third track with their first ends close together, and a second sliding channel is formed on one outer edge of the second track and the third track; the second track is hinged to the line body, the first track includes a first break, the second track is disposed at the first break, the third track is fixed to the line body, and the second end of the third track extends in a direction away from the first sliding channel; wherein, when the second track continues to extend in the direction of the first sliding channel, the auxiliary track maintains its initial state; when the second end of the second track swings in a direction close to the first sliding channel and remains in contact with the extension line of the first track, the auxiliary track enters a track-changing state.

[0017] In this technical solution, the operation of the express sorting vehicle will cause the lever to slide along the first sliding channel. When the auxiliary track enters the track changing state, the first sliding channel will connect with the corresponding second sliding channel. As the express sorting vehicle runs, the lever will also be guided by the second track to the second sliding channel, thereby causing the lever to slide along the width direction of the line, inputting power to the core and driving the roller assembly to operate.

[0018] In one technical solution of the present invention, the line body is configured as a loop; the first track further includes a second break portion, and the track changing device further includes a fourth track disposed on the line body and located at the second break portion. The first end of the fourth track is connected to the second break portion, and the second end of the first track extends away from the first sliding channel. The fourth track and the third track are located on the same side of the first sliding channel. A third sliding channel is formed on one outer edge of the fourth track. The distance between the end of the third sliding channel close to the first sliding channel and the first sliding channel relative to the width direction of the line body is greater than the distance between the end of the second sliding channel away from the first sliding channel relative to the width direction of the line body. The direction in which the first track, the second track and the third track are sequentially disposed is set as the positive direction, and the fourth track is disposed on the rear side of the third track along the positive direction.

[0019] In this technical solution, after the lever is guided from the first sliding channel to the second sliding channel by the auxiliary rail, the lever will slide along the second sliding channel. After sliding a certain distance, it may detach from the second sliding channel and then slide freely on the line, no longer bearing the force along the width of the line. When the express delivery vehicle moves to the fourth track position, the lever will gradually fit with the fourth track and, guided by the fourth track, gradually slide towards the first channel until it re-enters the first sliding channel to perform the next express delivery sorting action, thus realizing the continuous operation of express delivery sorting.

[0020] The positive direction is the direction of operation of the delivery vehicle. The fourth track is located behind the third track. At the same time, by limiting the distance between the end of the third sliding channel closest to the first sliding channel and the first sliding channel relative to the width of the line, it can be ensured that after the lever leaves the second sliding channel, as the delivery vehicle moves, the lever will interfere with the third sliding channel and be guided back to the first sliding channel, thus ensuring that the express sorting operation can be carried out continuously and reliably.

[0021] In one technical solution of the present invention, the first disconnection portion is configured as a plurality of interleaved portions arranged along the first track to form a plurality of continuous auxiliary tracks corresponding to the first track; the plurality of continuous auxiliary tracks correspond to a fourth track, and the fourth track is located on the rear side of the plurality of continuous auxiliary tracks in the positive direction.

[0022] In this technical solution, the first break section is set on the first track in multiple ways to set up multiple continuous auxiliary tracks. In this way, the track changing device can enable multiple express delivery vehicles to perform express delivery sorting operations simultaneously.

[0023] One fourth track corresponds to multiple consecutive auxiliary tracks. When the express sorting vehicle finishes the express sorting action and passes through the fourth track, the fourth track will reset all the express sorting vehicle levers in sequence, so that it can re-enter the first sliding channel and prepare for the next express sorting cycle.

[0024] In one technical solution of the present invention, the auxiliary track and the fourth track are configured as two corresponding sets located on both sides of the main track along the width direction of the track body.

[0025] In this technical solution, the auxiliary track and the fourth track are set as two corresponding sets on both sides of the main track along the width direction of the line body. Correspondingly, the core of the express sorting vehicle is also set as two sets, and the roller assembly can be set as two layers matching the core. That is, the sorting platform will form a double layer to improve the express sorting efficiency.

[0026] In one embodiment of the present invention, the second end of the second track has a guide surface.

[0027] In this technical solution, the guide surface is used to guide the lever, so that the lever can smoothly enter the second sliding channel or remain in the first sliding channel.

[0028] In one technical solution of the present invention, the track changing device further includes a limiting block for limiting the angle at which the second track swings away from the first sliding channel.

[0029] In this technical solution, the limiting block is used to limit the maximum swing angle of the second track away from the first sliding channel, thereby ensuring that the second track can reliably compensate for the first break when the auxiliary track maintains its initial state.

[0030] In one technical solution of the present invention, the track changing device further includes a driving member, which is disposed on the line body and is used to drive the second track to swing.

[0031] In this technical solution, the driving component is used to drive the second track to swing, thereby enabling the second track to actively enter the track-changing state at the required time, so that the express delivery vehicle can perform express sorting actions.

[0032] In one technical solution of the present invention, the track changing device further includes a reset member for resetting the second track to the state of closing the first disconnection part; the reset member includes a spring, the two ends of which abut against the second track and the line body respectively.

[0033] In this technical solution, the reset member is used to reset the second track to the state of closing the first disconnection part. It can be set as a spring, with the two ends of the spring abutting the connecting lugs extending from the second track and the connecting lugs extending from the line body, respectively.

[0034] Secondly, the present invention provides an express sorting and transportation line, including the track changing device in any of the above technical solutions, and also includes an express sorting vehicle running along the line; the express sorting vehicle includes a frame and a mechanism disposed on the frame, the mechanism includes a lever, and the express sorting vehicle performs express sorting actions when the lever slides relative to the frame.

[0035] In this technical solution, the track-changing device is applied to the express sorting and transportation line. The track-changing device works in conjunction with the machine core to drive the roller assembly to achieve purely mechanical operation.

[0036] (III) Beneficial Effects

[0037] The beneficial effects of the present invention are as follows: In the track changing device and express sorting and transportation line of the present invention, the main track is the main track on the line body, which is fixed on the line body to form a fixed first sliding channel; the auxiliary track is the auxiliary track on the line body, which is movably installed on the line body and can perform track changing action, and can connect the second sliding track to the first sliding track as needed.

[0038] When the auxiliary track is in the initial state, the second sliding channel is not connected to the first sliding channel, the lever will continue to slide along the first sliding channel, the mechanism will not receive power input, the roller assembly cannot operate, and the express delivery on the roller assembly will not move relative to the roller assembly.

[0039] When the auxiliary track is in the track changing state, the second sliding channel will be inserted into the first sliding channel. When the express delivery vehicle runs along the line, the lever at the corresponding position will slide from the first sliding channel into the second sliding channel, thereby driving the lever to slide along the width of the line. At the same time, power is input to the mechanism, driving the rotating roller assembly to run and perform the express delivery sorting action, that is, throwing the express delivery off the rotating roller assembly.

[0040] Compared with existing technologies, the operation of the express sorting vehicle can be used to make the roller assembly rotate, thus making the express sorting vehicle a purely mechanical structure, which greatly improves its reliability and also helps to reduce the cost of the express sorting vehicle.

[0041] Therefore, there is no need to install electric rollers and power supply modules on the express sorting vehicle. The express sorting vehicle requires almost no maintenance during use, which improves the efficiency of express sorting. The purely mechanical express sorting vehicle also improves the safety of the express sorting process. Attached Figure Description

[0063] To better explain and facilitate understanding of this invention, the following description is provided in conjunction with the appendix. Figure 1-9 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 1 The orientation is used as a reference.

[0064] Example 1:

[0065] An embodiment of the present invention provides a track-changing device I, including a line body 1 and a main track 2 and an auxiliary track 3 disposed on the line body 1; the main track 2 has a first sliding channel A extending along the length direction of the line body 1; the auxiliary track 3 has a second sliding channel B extending along the length direction of the line body 1, one end of the second sliding channel B being a first end adjacent to the first sliding channel A, and the other end being a second end extending away from the first sliding channel A along the width direction of the line body 1; wherein, the auxiliary track 3 includes an initial state and a track-changing state, when the auxiliary track 3 maintains the initial state, the first sliding channel A remains continuous; when the auxiliary track 3 maintains the track-changing state, the first end of the second sliding channel B is connected to the first sliding channel A.

[0066] An embodiment of the present invention also provides an express sorting and transportation line, including the track changing device I in the above technical solution, and an express sorting vehicle II running along the line body 1; the express sorting vehicle II includes a frame 8 and a mechanism 9 disposed on the frame 8, the mechanism 9 includes a lever, and the express sorting vehicle II performs express sorting actions when the lever slides relative to the frame 8.

[0067] In this embodiment, the track-changing device I is applied to the express sorting and transportation line. The track-changing device I works in conjunction with the core 9 to drive the roller assembly to achieve purely mechanical operation.

[0068] In this embodiment, the main track 2 serves as the main track on the line 1, and it is fixed to the line 1 to form a fixed first sliding channel A; the auxiliary track 3 is an auxiliary track on the line 1, which is movably installed on the line 1 and can perform track changing actions, connecting the second sliding track to the first sliding track as needed.

[0069] When the auxiliary track 3 is in the initial state, the second sliding channel B is not connected to the first sliding channel A, the lever will continue to slide along the first sliding channel A, the mechanism 9 will not receive power input, the roller assembly cannot operate, and the express delivery on the roller assembly will not move relative to the roller assembly.

[0070] When the auxiliary track 3 is in the track changing state, the second sliding channel B will be inserted into the first sliding channel A. When the express delivery vehicle runs along the line 1, the lever at the corresponding position will slide from the first sliding channel A into the second sliding channel B, thereby driving the lever to slide along the width of the line 1. At the same time, power is input to the mechanism 9, driving the rotating roller assembly to run and perform the express delivery sorting action, that is, throwing the express delivery off the rotating roller assembly.

[0071] Compared with existing technologies, the operation of the express sorting vehicle II can be used to make the roller assembly rotate, thus making the express sorting vehicle II a purely mechanical structure, which greatly improves its reliability and also helps to reduce the cost of the express sorting vehicle II.

[0072] Therefore, there is no need to install electric rollers and power supply modules on the Express Sorting Cart II. The Express Sorting Cart II requires almost no maintenance during use, which improves the efficiency of express sorting. The purely mechanical Express Sorting Cart II also improves the safety of the express sorting process.

[0073] Specifically, the mechanism 9 includes a sliding member and a transmission member. The sliding member is slidably connected to the frame 8 along the width direction of the frame 8, and the transmission member is located on the frame 8. The sliding member is used to bear the load along the width direction of the frame 8 to drive the transmission member to run, thereby driving the roller assembly to run. A lever extends from the sliding member.

[0074] More specifically, the transmission component includes a first transmission assembly, which is drivenly connected to the roller assembly; 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 8, a sliding member is connected to the first chain, and one first sprocket is drivenly connected to the torque input end of the roller assembly.

[0075] The transmission component also includes a second transmission component that establishes the linkage between the first transmission component and the roller assembly. 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 roller assembly.

[0076] The main track 2 includes two nested first tracks 21, forming a first sliding channel A between them; the auxiliary track 3 includes a second track 31 and a third track 32 with their first ends close together, and a second sliding channel B is formed on one outer edge of the second track 31 and the third track 32; the second track 31 is hinged to the line body 1, the first track 21 includes a first break C, the second track 31 is disposed at the first break C, the third track 32 is fixed to the line body 1, and the second end of the third track 32 extends in a direction away from the first sliding channel A; wherein, when the second track 31 continues to extend in the direction of the first sliding channel A, the auxiliary track 3 maintains its initial state; when the second end of the second track 31 swings in a direction close to the first sliding channel A and remains in contact with the extension line of the first track 21, the auxiliary track 3 enters a track-changing state.

[0077] In this embodiment, the operation of the express sorting vehicle II will cause the lever to slide along the first sliding channel A. When the auxiliary track 3 enters the track changing state, the first sliding channel A will connect with the corresponding second sliding channel B. As the express sorting vehicle II runs, the lever will also be guided by the second track 31 to the second sliding channel B, thereby causing the lever to slide along the width direction of the line body 1, inputting power to the mechanism 9, and driving the roller assembly to run.

[0078] The first break section C is the first break area on the continuous first track 21; optionally, when the auxiliary track 3 is in the initial state, the second track 31 can just compensate for the first break area.

[0079] Specifically, the auxiliary track 3 also includes a transition section 33, which is used to transition between the first end of the second track 31, the end of the first track 21, and the first end of the third track 32, so as to prevent the lever from jumping when it passes through this position.

[0080] More specifically, the transition portion 33 may be made of rubber sheet and is set at this position by adhesive bonding.

[0081] When the second track 31 swings, it cannot interfere with the third track 32 and the first track 21. With the presence of a transition plate, a certain distance can be made between the first end of the second track 31 and the end of the first track 21 and the first end of the third track 32.

[0082] The second end of the second track 31 has a guide surface F.

[0083] In this embodiment, the guide surface F is used to guide the lever, so that the lever can smoothly enter the second sliding channel B, or remain sliding in the first sliding channel A.

[0084] The track-changing device I also includes a drive unit 6, which is located on the line body 1 and is used to drive the second track 31 to swing.

[0085] In this embodiment, the driving component 6 is used to drive the second track 31 to swing, thereby enabling the second track 31 to actively enter the track-changing state at the required time, so that the express delivery vehicle can perform express delivery sorting actions.

[0086] Specifically, the drive component 6 can be configured as either a pneumatic telescopic component or a hydraulic telescopic component.

[0087] In this embodiment, the track changing device I further includes a reset member 7, which is used to reset the second track 31 to the state of closing the first disconnection part C; the reset member 7 includes a spring, the two ends of which abut against the second track 31 and the line body 1 respectively.

[0088] In this embodiment, the reset member 7 is used to reset the second track 31 to the state of closing the first disconnection part C. It can be set as a spring, with the two ends of the spring abutting the connecting lugs extending from the second track 31 and the connecting lugs extending from the line body 1, respectively.

[0089] The drive unit 6 is controlled by the control system. Each express sorting car II has a unique number. An identification device can be set on the line 1 to identify the number of the express sorting car II. When an express sorting car II with a specific number needs to perform express sorting, the drive unit 6 is controlled to run after the express sorting car II runs to the designated position. In this way, the core 9 of the express sorting car II will receive driving force and drive the roller assembly to perform express sorting.

[0090] Since each drive unit 6 can be controlled independently, the continuous express sorting vehicle II can perform express sorting actions at different required positions, which greatly improves the flexibility of the express sorting vehicle II.

[0091] The use of this track-type mechanism 9 drive mode, due to its simple mechanical structure, results in fast response and small error, thus allowing the express sorting vehicle II to operate at a higher speed, greatly improving express sorting efficiency.

[0092] Specifically, the express sorting vehicle II is configured to operate via a friction drive device on the line. That is, friction plates are installed on the express vehicle frame 8, and the friction plates contact the friction wheel of the friction drive device. The friction force drives the friction plates to move, which in turn drives the frame 8 to move.

[0093] Example 2:

[0094] In addition to possessing all the technical solutions of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0095] Line 1 is configured as a loop; the first track 21 also includes a second break D, and the track changing device I also includes a fourth track 4 disposed on line 1 and located at the second break D. The first end of the fourth track 4 is connected to the second break D, and the second end of the first track 21 extends away from the first sliding channel A. The fourth track 4 and the third track 32 are located on the same side of the first sliding channel A. A third sliding channel E is formed on one outer edge of the fourth track 4. The distance between the third sliding channel E and the first sliding channel A in the width direction of line 1 is greater than the distance between the second sliding channel B and the end of the second sliding channel B away from the first sliding channel A in the width direction of line 1. The direction in which the first track 21, the second track 31 and the third track 32 are sequentially disposed is set as the positive direction, and the fourth track 4 is disposed on the rear side of the third track 32 along the positive direction.

[0096] In this embodiment, after the lever is guided from the first sliding channel A to the second sliding channel B by the auxiliary rail 3, the lever will slide along the second sliding channel B. After sliding a certain distance, it may detach from the second sliding channel B and then slide freely on the line body 1, that is, it will no longer bear the force along the width direction of the line body 1. When the express delivery vehicle runs to the position of the fourth rail 4, the lever will gradually fit with the fourth rail 4 and, under the guidance of the fourth rail 4, gradually slide towards the first channel until it re-enters the first sliding channel A to perform the next express delivery sorting action, so as to realize the continuous operation of express delivery sorting.

[0097] The positive direction is the direction of operation of the delivery vehicle. The fourth track 4 is located behind the third track 32. At the same time, by limiting the distance between the end of the third sliding channel E close to the first sliding channel A and the first sliding channel A in the width direction relative to the line body 1 to be greater than the distance between the end of the second sliding channel B away from the first sliding channel A and the width direction relative to the line body 1, it can be ensured that after the lever is disengaged from the second sliding channel B, as the delivery vehicle moves, the lever will interfere with the third sliding channel E and be guided back to the first sliding channel A, thus ensuring that the express sorting operation can be carried out continuously and reliably.

[0098] Example 3:

[0099] In addition to possessing all the technical solutions of any of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0100] The first disconnection C is configured as multiple sections that are staggered along the first track 21 to form multiple consecutive auxiliary tracks 3 corresponding to the first track 21; the multiple consecutive auxiliary tracks 3 correspond to a fourth track 4, and the fourth track 4 is located on the rear side of the multiple consecutive auxiliary tracks 3 in the positive direction.

[0101] In this embodiment, there are multiple first disconnections C on the first track 21 to set multiple continuous auxiliary tracks 3. In this way, the track changing device I can enable multiple express delivery vehicles to perform express delivery sorting operations at the same time.

[0102] One fourth track 4 corresponds to multiple consecutive auxiliary tracks 3. When the express sorting vehicle II finishes the express sorting action and passes through the fourth track 4, the fourth track 4 will reset all the levers of the express sorting vehicle II in sequence, so that it can re-enter the first sliding channel A and prepare for the next express sorting cycle.

[0103] Specifically, the second sliding channel B and the third sliding channel E can be configured as an arc-shaped channel, an involute channel, or a straight channel. When both are configured as arc-shaped channels or involute channels, the second sliding channel B is concave towards the first sliding channel A, and the third sliding channel E is concave away from the first sliding channel A.

[0104] Example 4:

[0105] In addition to possessing all the technical solutions of any of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0106] The auxiliary track 3 and the fourth track 4 are set as two corresponding sets located on both sides of the main track 2 along the width direction of the line body 1.

[0107] In this embodiment, the auxiliary track 3 and the fourth track 4 are set as two corresponding sets located on both sides of the main track 2 along the width direction of the line body 1. Correspondingly, the core 9 on the express sorting vehicle II is also set as two sets, and the roller assembly can be set as two layers matching the core 9. That is, the sorting platform will form a double layer to improve the express sorting efficiency.

[0108] Example 5:

[0109] In addition to possessing all the technical solutions of any of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0110] The track-changing device I also includes a limiting block 5, which limits the angle at which the second track 31 swings away from the first sliding channel A.

[0111] In this embodiment, the limiting block 5 is used to limit the maximum swing angle of the second track 31 away from the first sliding channel A, thereby ensuring that the second track 31 can reliably compensate for the first disconnection C when the auxiliary track 3 remains in its initial state.

[0112] Specifically, the limiting block 5 can be set as a rubber block or a nylon block.

[0113] More specifically, the limiting block 5 can be set between the adjacent second track 31 and the third track 32 corresponding to the adjacent auxiliary track 3, and connected to the third track 32.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
