[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0027] Embodiment 1, as Figure 1-6 As shown, a double-side unloading flip-plate sorting mechanism comprises a running track 1 and a traveling frame 2, the traveling frame 2 is slidably connected in the running track 1, a support block 3 is fixedly installed above the traveling frame 2, and support plates 4 are fixedly installed on both the front and rear sides of the support block 3, and a limit shaft 5 is horizontally installed on the upper end of the support plate 4, and the two ends of the limit shaft 5 respectively pass through the two support plates 4; a support plate assembly is arranged above the support block 3;

[0028] The support plate assembly includes a hollow rotating seat 6 and a support plate 7, the support plate 7 is fixedly mounted on the upper surface of the hollow rotating seat 6, a flip shaft 8 is fixedly mounted on the lower end of the hollow rotating seat 6, both ends of the flip shaft 8 are rotatably connected to the support plate 4 through bearings, the limit shaft 5 and the flip shaft 8 are both arranged parallel to the axial direction of the running track 1, and the limit shaft 5 is located directly above the flip shaft 8; arc slots 9 are provided on the front and rear sides of the rotating seat 6, the limit shaft 5 passes through the arc slots 9 and is movably matched with the arc slots 9; in this embodiment, a limit slot 15 is provided on the middle upper side surface of the arc slot 9, the two ends of the limit slot 15 are smoothly transitioned to the arc slot 9, and the depth of the limit slot 15 matches the diameter of the limit shaft 5.

[0029] Push rod assemblies are symmetrically installed on the left and right sides of the running track 1, and trigger blocks 25 are fixedly installed on the left and right sides of the hollow rotating seat 6. The pushing end of the push rod assembly flexibly conflicts with the trigger block 25.

[0030] Working principle:

[0031] First, the running track 1 is fixed on the gantry of the sorting machine, and the traveling frame 2 is driven by the motor to run along the running track 1 at a set speed. In the initial state, the limit shaft 5 on the upper end of the support plate 4 is engaged with the limit notch 15 of the arc slot 9 to ensure that the support plate 7 can be stably in a horizontal position. Therefore, the support plate 7 can carry mail parcels of various special-shaped structures. Then, the driving mechanism drives the traveling frame 2 to move along the running track 1.

[0032] When the traveling frame 2 runs to the designated position, the push rod assembly on one side of the running track 1 is controlled to start, so as to control the pushing end of the push rod assembly to contact the trigger block 25, so as to push the hollow rotating seat 6 to rotate, so that the limit shaft 5 is disengaged from the limit slot 15 and slides along the arc slot 9, thereby driving the entire hollow rotating seat 6 to rotate and tilt around the flip shaft 8 to the other side of the running track 1, thereby driving the pallet 7 to tilt to a predetermined angle. At this time, the limit shaft 5 slides along the arc slot 9 to the limit position, ensuring that the pallet 7 is stably tilted, and the mail package smoothly slides along the pallet under the action of gravity to the sorting grid on the other side of the running track 1. Afterwards, the push rod assembly on the other side of the running track 1 is controlled to start, so as to push the hollow rotating seat 6 to reset in the opposite direction through the pushing end of the push rod assembly, so that the limit shaft 5 re-enters the limit slot 15, the pallet 7 returns to a horizontal state, and the traveling frame 2 continues to move forward to prepare for the next round of sorting tasks. In this embodiment, sorting grids can be symmetrically arranged on both the left and right sides of the running track 1, so that after the traveling frame 2 runs to the specified position, the sorting direction can be flexibly selected according to the needs, so as to effectively realize efficient two-way sorting, thereby improving the utilization rate of the entire carrying sorting unit. The number of internal sorting grids per unit length of the running track 1 is doubled.

[0033] The above structural design not only improves the sorting efficiency, but also reduces the equipment footprint, optimizes the sorting process, and reduces operating costs. At the same time, the symmetrically arranged push rod assembly ensures the smooth resetting of the hollow rotating seat 6, prolongs the service life of the equipment, and further improves the stability and reliability of the sorting system. When the walking frame 2 reaches the specified position again, the control system accurately adjusts the push rod assembly to ensure that the rotation angle of the rotating seat 6 and the inclination of the pallet 7 are perfectly matched, and the mail package slides smoothly into the corresponding sorting grid. Thereby realizing the automation and intelligence of the sorting process, greatly improving the sorting accuracy and efficiency, and providing a solid guarantee for the efficient operation of the logistics industry.

[0034] Embodiment 2, as Figure 6 As shown, as a further preferred embodiment of the first embodiment, the push rod assembly includes a mounting seat 10, a push rod 11 and a telescopic motor 12. The mounting seat 10 is fixed on the running track 1, and the telescopic motor 12 is fixedly installed on the upper surface of the mounting seat 10. The side of the mounting seat 10 close to the walking frame 2 is rotatably connected to the lower end of the push rod 11 through a rotating shaft, and the upper end of the push rod 11 is in active contact with the trigger block 25; a slide rail 13 is provided on the side of the push rod 11 away from the walking frame 2, and the telescopic end of the telescopic motor 12 is rotatably connected to the sliding block 14 through a joint bearing 24, and the sliding block 14 is slidably connected in the slide rail 13.

[0035] Therefore, when the pushing end of the control push rod assembly pushes the hollow rotating seat 6, the telescopic end of the telescopic motor 12 is directly controlled to extend, so as to utilize the flexible rotation of the joint bearing 24 and the smooth movement of the sliding block to cooperate to push the push rod 11 to rotate around the rotating axis, and then the upper end of the push rod 11 is rotated toward the hollow rotating seat 6 to apply a thrust to the trigger block 25 to ensure that the rotating seat 6 rotates smoothly to a predetermined angle, thereby accurately controlling the inclination of the pallet 7, ensuring that the mail package slides smoothly into the designated sorting grid, and further improving the sorting efficiency and accuracy.

[0036] Embodiment 3, as a further preferred solution of Embodiment 2, a rubber-coated bearing 20 is rotatably mounted on the upper end of the push rod 11, and the rubber-coated bearing 20 is in active contact with the trigger block 25. The rubber-coated bearing 20 is provided to ensure that there is a certain amount of rolling displacement between the rubber-coated bearing 20 and the trigger block 25 to effectively reduce friction resistance, and the buffering effect of the rubber-coated bearing 20 can also be used to reduce the operating noise of the equipment and improve the operating stability.

[0037] Furthermore, a shock-absorbing buffer pad can be installed on the outer side of the trigger block 25, so that the rubber-coated bearing 20 cooperates with the shock-absorbing buffer pad to effectively absorb vibration, further reduce noise, and improve the stability and durability of equipment operation.

[0038] Embodiment 4, as a further preferred scheme of embodiment 1, the support plate 4 includes an inner support plate 41 and an outer support plate 42, the inner support plate 41 is fixedly installed on the front and rear sides of the support block 3, and the outer support plate 42 is fixedly installed on the outer side of the inner support plate 41 by bolts; a guide column 16 is fixedly installed on the upper end of the outer support plate 42, and a support block 17 is movably sleeved on the outer surface of the guide column 16, and the two ends of the limit shaft 5 respectively pass through the two support blocks 17 and are connected to the support blocks 17; a buffer groove 18 is opened on the upper end surface of the outer support plate 42, and the bottom of the buffer groove 18 is connected to one end of the spring 19, and the other end of the spring 19 is fixedly connected to the support block 17.

[0039] Therefore, when the pallet 7 is carrying mail packages, the elastic buffering effect of the spring 19 can make the support block 17 move up and down along the guide column 16, thereby effectively ensuring the horizontal stability of the pallet 7 and preventing the mail packages from slipping, thereby further ensuring that the support block 17 can remain stable when carrying mail packages of different weights, further optimizing the stability and safety of the sorting system.

[0040] Embodiment 5, as a further preferred solution of embodiment 4, a plurality of vertically arranged strip holes are evenly opened on the surface of the outer support plate 42, and bolts are movably installed in the strip holes, and the bolts pass through the strip holes and are fixedly connected to the inner support plate 41. Therefore, when installing the outer support plate 42, the bolts can be directly inserted into the strip holes and tightened to ensure that the outer support plate 42 is tightly combined with the inner support plate 41, and through the design of the strip holes, the upper and lower positions of the outer support plate 42 can be adaptively fine-tuned to effectively ensure the fit between the limit shaft 5 and the limit slot 15, and then ensure the precise positioning and stability of the support plate 7 during the movement.

[0041] Embodiment 6, as a further preferred solution of embodiment 1, first rollers 21 are installed on both the left and right sides of the traveling frame 2, and slide grooves 22 are provided on both the left and right sides of the inner wall of the running track 1, and the first roller 21 is embedded in the slide grooves 22 and movably cooperates with the slide grooves 22; second rollers 23 are installed on the left and right sides of the bottom of the traveling frame 2, and the second rollers 23 are in contact with the left and right sides of the inner wall of the running track 1. Through the cooperation of the first roller 21 and the slide groove 22, the traveling frame 2 moves smoothly in the running track 1, and provides additional support to ensure that the traveling frame 2 moves smoothly along the track. At the same time, the second roller 23 is installed at the bottom of the traveling frame 2, and cooperates with the left and right sides of the inner wall of the running track 1, so as to further stabilize the running track of the traveling frame, reduce lateral shaking, and ensure the accuracy and reliability of the overall sorting system.

[0042] Embodiment 7, as a further preferred solution of Embodiment 1, electric telescopic rods are installed on both the left and right sides of the running track 1, and the telescopic ends of the electric telescopic rods pass through the through holes of the side walls of the running track 1 and cooperate with the left and right sides of the traveling frame 2. Therefore, when the traveling frame 2 moves in the running track 1, the telescopic shaft of the electric telescopic rod can be controlled to extend to achieve accurate limitation of the moving position of the traveling frame 2, thereby ensuring that the traveling frame 2 can be accurately positioned during the sorting process, thereby improving the overall sorting efficiency.

[0043] In the present invention, a controller may be provided, and the signal output end of the controller is respectively connected to the signal input end of the motor drive mechanism, the telescopic motor 12, and the electric telescopic rod of the traveling frame 2. Thus, the control chip in the controller can realize the driving control of the motor drive mechanism, the telescopic motor 12, and the electric telescopic rod of the traveling frame 2, so as to realize the automatic control effect.
