Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0027] Example 1, as Figures 1-6 As shown, a two-sided unloading flip-plate sorting mechanism includes a running track 1 and a walking frame 2. The walking frame 2 is slidably connected in the running track 1. A support base 3 is fixedly installed on the top of the walking frame 2. Support plates 4 are fixedly installed on both the front and rear sides of the support base 3. A limit shaft 5 is horizontally installed on the upper end of the support plate 4. The two ends of the limit shaft 5 pass through the two support plates 4 respectively. A pallet assembly is provided above the support base 3.

[0028] The pallet assembly includes a hollow rotating seat 6 and a pallet 7. The pallet 7 is fixedly installed on the upper surface of the hollow rotating seat 6. A flipping shaft 8 is fixedly installed at the lower end of the hollow rotating seat 6. The two ends of the flipping shaft 8 are rotatably connected to the support plate 4 through bearings. The limiting shaft 5 and the flipping shaft 8 are both arranged parallel to the axial direction of the running track 1. The limiting shaft 5 is located directly above the flipping shaft 8. Arc-shaped slots 9 are provided on the front and rear sides of the rotating seat 6. The limiting shaft 5 passes through the arc-shaped slots 9 and is movably engaged with the arc-shaped slots 9. In this embodiment, a limiting slot 15 is provided on the upper middle side of the arc-shaped slot 9. The two ends of the limiting slot 15 smoothly transition with the arc-shaped slot 9. The depth of the limiting slot 15 matches the diameter of the limiting shaft 5.

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

[0030] Working principle:

[0031] First, the running track 1 is fixed on the gantry of the sorting machine. The traveling frame 2, driven by a motor, moves along the running track 1 at a set speed. In the initial state, the limiting shaft 5 at the upper end of the support plate 4 engages with the limiting slot 15 of the arc-shaped slot 9 to ensure that the pallet 7 is stably in a horizontal position. This allows the pallet 7 to carry mail packages of various irregular shapes. Then, the drive mechanism moves the traveling frame 2 along the running track 1.

[0032] Once the traveling frame 2 reaches the designated position, the pusher assembly on one side of the running track 1 is activated. The pushing end of the pusher assembly contacts the trigger block 25, causing the hollow rotating seat 6 to rotate. This causes the limiting shaft 5 to disengage from the limiting slot 15 and slide along the arc-shaped slot 9, thereby causing the entire hollow rotating seat 6 to rotate and tilt around the flipping shaft 8 to the other side of the running track 1. This tilts the pallet 7 to a predetermined angle. At this point, the limiting shaft 5 slides along the arc-shaped slot 9 to its limit position, ensuring the pallet 7 tilts stably. The mailbag then slides smoothly down the pallet under gravity into the sorting compartment on the other side of the running track 1. Afterward, the pusher assembly on the other side of the running track 1 is activated again, pushing the hollow rotating seat 6 back to its original position via its pushing end. This causes the limiting shaft 5 to re-enter the limiting slot 15, the pallet 7 returns to a horizontal state, and the traveling frame 2 continues forward, preparing for the next sorting task. In this embodiment, sorting slots can be symmetrically arranged on both the left and right sides of the running track 1, allowing the traveling frame 2 to flexibly select the sorting direction as needed after reaching the designated position, thereby effectively achieving efficient bidirectional sorting and improving the utilization rate of the entire carrying and sorting unit. This also multiplies the number of sorting slots per unit length of the running track 1.

[0033] The aforementioned structural design not only improves sorting efficiency but also reduces equipment footprint, optimizes the sorting process, and lowers operating costs. Simultaneously, the symmetrically arranged push rod assembly ensures the smooth return of the hollow rotating seat 6, extending the equipment's lifespan and further enhancing the stability and reliability of the sorting system. When the traveling frame 2 reaches the designated position again, the control system precisely adjusts the push rod assembly to ensure a perfect match between the rotation angle of the rotating seat 6 and the inclination of the pallet 7, allowing the mail package to smoothly slide into the corresponding sorting slot. This achieves automation and intelligence in the sorting process, significantly improving sorting accuracy and efficiency, and providing a solid guarantee for the efficient operation of the logistics industry.

[0034] Example 2, as Figure 6 As shown, as a further preferred embodiment of the first embodiment, the push rod assembly includes a mounting base 10, a push rod 11, and a telescopic motor 12. The mounting base 10 is fixed on the running track 1. The telescopic motor 12 is fixedly mounted on the upper surface of the mounting base 10. The lower end of the push rod 11 is rotatably connected to the side of the mounting base 10 near the walking frame 2 via a rotating shaft. The upper end of the push rod 11 is in movable 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. The telescopic end of the telescopic motor 12 is rotatably connected to a sliding block 14 via a spherical bearing 24. The sliding block 14 is slidably connected in the slide rail 13.

[0035] Therefore, when the pushing end of the push rod assembly pushes the hollow rotating seat 6, the telescopic end of the telescopic motor 12 is directly controlled to extend, so that the flexible rotation of the joint bearing 24 is matched with the smooth movement of the sliding block, so as to push the push rod 11 to rotate around the rotating shaft, and then the upper end of the push rod 11 rotates to the direction of the hollow rotating seat 6, so as to apply a pushing force to the trigger block 25, ensure that the rotating seat 6 rotates stably to a predetermined angle, accurately control the inclination of the supporting plate 7, ensure that the mail bag smoothly slides into the specified sorting pocket, and further improve the sorting efficiency and accuracy.

[0036] In embodiment three, as a further preferred solution of embodiment two, the upper end of the push rod 11 is rotatably installed with a rubber bearing 20, and the rubber bearing 20 is in movable contact with the trigger block 25. By arranging the rubber bearing 20, a certain rolling displacement amount between the rubber bearing 20 and the trigger block 25 is ensured, so as to effectively reduce the friction resistance, and the buffering effect of the rubber bearing 20 can also be used to reduce the equipment operation noise and improve the operation stability.

[0037] Further, a damping cushion can also be installed on the outer side of the trigger block 25, so that the rubber bearing 20 cooperates with the damping cushion to effectively absorb vibration, further reduce noise, and improve the stability and durability of the equipment operation.

[0038] In embodiment four, as a further preferred solution of embodiment one, the supporting plate 4 includes an inner supporting plate 41 and an outer supporting plate 42, the inner supporting plate 41 is fixedly installed on the front and rear sides of the supporting seat 3, and the outer supporting plate 42 is fixedly installed on the outer side of the inner supporting plate 41 by bolts; the outer supporting plate 42 is fixedly installed with a guide column 16 on the upper end, the guide column 16 is movably sleeved with a supporting block 17 on the outer surface, and the two ends of the limiting shaft 5 respectively penetrate through the two supporting blocks 17 and are connected with the supporting blocks 17; the outer supporting plate 42 is provided with a buffer groove 18 on the upper end surface, and the buffer groove 18 is connected with one end of a spring 19 at the bottom, and the other end of the spring 19 is fixedly connected to the supporting block 17.

[0039] Therefore, when the supporting plate 7 carries the mail bag, the supporting block 17 can move up and down along the guide column 16 through the elastic buffering effect of the spring 19, so as to effectively ensure the horizontal stability of the supporting plate 7 and avoid the mail bag from falling, thereby further ensuring that the supporting block 17 can remain stable when carrying mail bags of different weights, and further optimizing the stability and safety of the sorting system.

[0040] As a further preferred scheme of Embodiment Four, a plurality of vertically arranged strip-shaped holes are uniformly arranged on the surface of the outer support plate 42, and bolts are movably installed in the strip-shaped holes, and the bolts pass through the strip-shaped holes and are fixedly connected with the inner support plate 41. Therefore, when the outer support plate 42 is installed, the bolts can be directly inserted into the strip-shaped holes and fastened, so as to ensure that the outer support plate 42 is tightly combined with the inner support plate 41, and through the design of the strip-shaped holes, the up-down position of the outer support plate 42 can be adaptively and slightly adjusted, so as to effectively ensure the fitting degree of the limiting shaft 5 and the limiting notch 15, and then ensure the accurate positioning and stability of the supporting plate 7 in the movement process.

[0041] As a further preferred scheme of Embodiment One, first rollers 21 are installed on the left and right sides of the walking frame 2, sliding grooves 22 are arranged on the inner walls of the left and right sides of the running track 1, and the first rollers 21 are embedded in the sliding grooves 22 and movably cooperate with the sliding grooves 22; second rollers 23 are installed on the left and right sides of the bottom of the walking frame 2, and the second rollers 23 are in contact with the left and right sides of the inner walls of the running track 1. Through the cooperation of the first rollers 21 and the sliding grooves 22, the walking frame 2 can stably move in the running track 1, and additional support is provided to ensure that the walking frame 2 stably moves along the track. At the same time, the second rollers 23 are installed on the bottom of the walking frame 2 and cooperate with the left and right sides of the inner walls of the running track 1, which further stabilizes the running track of the walking frame, reduces lateral shaking, and ensures the accuracy and reliability of the whole sorting system.

[0042] As a further preferred scheme of Embodiment One, electric telescopic rods are installed on the left and right sides of the running track 1, the telescopic ends of the electric telescopic rods pass through the through holes in the side walls of the running track 1 and movably abut against the left and right sides of the walking frame 2. Therefore, when the walking frame 2 moves in the running track 1, the telescopic shafts of the electric telescopic rods can be controlled to extend, so as to accurately limit the moving position of the walking frame 2, thereby ensuring that the walking frame 2 can be accurately positioned during the sorting process, and improving the overall sorting efficiency.

[0043] In the utility model, a controller can also be arranged, and the signal output end of the controller is connected with the motor driving mechanism of the walking frame 2, the telescopic motor 12 and the signal input end of the electric telescopic rod. Therefore, the driving control of the motor driving mechanism of the walking frame 2, the telescopic motor 12 and the electric telescopic rod can be realized through the control chip in the controller, so as to realize the automatic control effect.
