Description

Technical Field

[0001] This invention belongs to the field of express sorting technology, specifically relating to an automatic sorting machine for logistics. Background Technology

[0002] In recent years, with the rapid development of the e-commerce industry, the number of online shoppers across the country has gradually increased, leading to a surge in express parcels and driving the growth of the logistics industry. Among these factors, parcel sorting has become one of the main reasons affecting delivery time. Once parcels arrive at a transit station, they need to be sorted together based on their destination. Currently, parcel sorting is achieved using specialized sorting equipment.

[0003] For example, the utility model patent with patent authorization announcement number CN209829620U provides an automatic parcel sorting line, including a parcel feeding device, a measuring and scanning device, a parcel side-mounting device, a parcel sorting device, and a control device arranged sequentially along the conveying direction of the parcels. The measuring and scanning device includes a volume measuring component for measuring the volume information of the parcels, a weighing platform for weighing the weight information of the parcels, and a scanning component for identifying the barcode information of the parcels. The parcel sorting device includes multiple parcel sorting components arranged sequentially. The control device is electrically connected to the volume measuring component, the weighing platform, the scanning component, and the multiple parcel sorting components.

[0004] Based on the search of the aforementioned patent grant announcement numbers, and considering their shortcomings, the following was found:

[0005] In existing express sorting lines, because the sorting warehouse space is large enough and the sorting areas are all at the same height, it is only necessary to set up an express sorting line next to several sorting areas to transport express packages to the corresponding sorting areas. However, in cases where warehouse space and layout are limited, multiple sorting areas may have different heights. In this case, using a single express sorting line can no longer meet the sorting needs of express packages. Summary of the Invention

[0006] To address the issue of limited warehouse space and layout, where multiple sorting areas have different heights, and where a single express sorting line is insufficient for express sorting, this invention provides an automated sorting machine for logistics.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] An automatic sorting machine for logistics includes a first conveyor line with an input port and an output port at both ends, a second conveyor line, and a sorting assembly. The second conveyor line is located at the bottom of the first conveyor line and has an input port and an output port at both ends. The first conveyor line has a lane-changing opening. The sorting assembly includes a first drive belt and a drive unit. The first drive belt is located inside the lane-changing opening and is hinged to one end of the first conveyor line. The drive unit is mounted on top of the first conveyor line, and its output end is hinged to the first drive belt for controlling the rotation of the first drive belt. The input port is located directly below the lane-changing opening.

[0009] As a preferred embodiment of the present invention, the sorting assembly further includes a second transmission belt, which is symmetrically arranged at the other end of the switching port relative to the first transmission belt. The second transmission belt is hinged to one end of the first conveyor line. The hinge points of the first transmission belt and the second transmission belt are respectively located at the two ends of the switching port. The driving unit is hinged to the second transmission belt. The second transmission belt and the first transmission belt have the same rotation angle and opposite rotation directions.

[0010] As a preferred embodiment of the present invention, the drive unit includes a retaining rod and a hinge unit. The retaining rod is horizontally mounted on the top of the first conveyor line, and the central axis of the retaining rod is projected onto the surface of the first conveyor line on the line of symmetry of the switching point. The hinge unit includes a hinge block and two hinge rods. The center of the hinge block is rotatably coaxially connected to the retaining rod. The two hinge rods are located at both ends of the hinge block, and the two hinge rods are matched one-to-one with two transmission belts. The two ends of any one of the hinge rods are respectively hinged to one end of the hinge block and one end of the transmission belt.

[0011] As a preferred embodiment of the present invention, the drive unit further includes a drive motor, a drive block, and a drive rod. The drive motor is mounted on the top of the first conveyor line. The output end of the drive motor is connected to one end of the drive block. The two ends of the drive rod are respectively hinged to the other end of the drive block and the end of the hinge block near the second transmission belt.

[0012] As a preferred embodiment of the present invention, the initial angle of the drive block is tilted, and when viewed along the rotation direction of the output end of the drive motor, the end of the drive block closest to the drive rod rotates towards the top.

[0013] As a preferred embodiment of the present invention, the minimum height of the first transmission belt is higher than the setting height of the second conveyor line.

[0014] As a preferred embodiment of the present invention, it further includes a stabilizing component, which includes a stabilizing plate and a stabilizing rod. The stabilizing plate is disposed at the bottom of the second transmission belt, and the two ends of the stabilizing rod are respectively connected to the stabilizing plate and the second transmission belt. After the first transmission belt rotates towards the bottom, the surface of the first transmission belt and the surface of the stabilizing plate are on the same inclined plane.

[0015] As a preferred embodiment of the present invention, the surface of the stabilizing plate is arranged parallel to the surface of the second transmission belt.

[0016] As a preferred embodiment of the present invention, the stabilizing component further includes a plurality of rotating units, which are equally spaced on the stabilizing plate along the transport direction of the second conveyor line. Each rotating unit includes a plurality of rotating beads and a rotating rod. The rotating rod is rotatably mounted on the stabilizing plate, and the plurality of rotating beads are coaxially mounted on the rotating rod at equal intervals along the axial direction of the rotating rod. The top height of the rotating beads is higher than the surface height of the stabilizing plate.

[0017] As a preferred embodiment of the present invention, the rotating unit further includes a connecting gear, a driving gear, and a driving ring. The connecting gear is rotatably disposed on the side wall of the stable plate and is coaxially connected to the rotating rod. The driving gear is rotatably disposed on the side wall of the stable plate and meshes with the connecting gear. The driving ring is coaxially connected to the driving gear and can lock or release its abutment relationship with the surface of the second conveyor line.

[0018] The beneficial effects of this invention are as follows:

[0019] By setting up a drive unit and a first transmission belt, it should be noted that the first transmission belt in this solution is a conveyor structure with express delivery function; the first transmission belt can rotate under the control of the drive unit; when the first transmission belt rotates to a state where its surface coincides with the surface of the first conveyor line, the express delivery can be transported on the first conveyor line; when the first transmission belt rotates to a certain angle, the express delivery on the first conveyor line will move to the second conveyor line through the rerouting port, so that the express delivery can be transported on the second conveyor line. This solves the problem of multiple sorting areas with different heights when warehouse space and layout are limited, in which case a single express delivery sorting line can no longer meet the express delivery sorting needs.

Detailed Implementation

[0032] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0033] Please see Figures 1-9 This embodiment provides an automatic sorting machine for logistics, including a first conveyor line 1. The first conveyor line 1 has an input port 101 and an output port 102 at both ends. The input port 101 is used for manually placing packages onto the first conveyor line 1. The output port 102 corresponds to a package sorting area within the warehouse. When a package arrives at the output port 102, it is sorted into that specific sorting area. The machine also includes a second conveyor line 2 and a sorting assembly 3. The second conveyor line 2 is located at the bottom of the first conveyor line 1. The second conveyor line 2 has an input port 201 and an output port 202 at both ends. The input port 201 of the second conveyor line 2 is used for placing packages onto the second conveyor line 2. The output port 202 corresponds to another package sorting area within the warehouse. When a package arrives at the output port 202, it is sorted into another specific sorting area. Since the two express sorting areas in this solution are at different heights, the first conveyor line 1 and the second conveyor line 2 are set at different heights. Furthermore, it is worth noting that both the first conveyor line 1 and the second conveyor line 2 in this solution are conveying structures capable of transporting express packages. Further, the first conveyor line 1 in this solution has a switching point 103. The sorting component 3 includes a first drive belt 301 and a drive unit 4. The first drive belt 301 is located within the switching point 103 and is hinged to one end of the first conveyor line 1. The drive unit 4 is mounted on top of the first conveyor line 1, and its output end is hinged to the first drive belt 301 to control its rotation. The inlet 201 is located directly below the switching point 103. By including the drive unit 4 and the first drive belt 301, it should be noted that the first drive belt 301 in this solution is a conveying structure capable of transporting express packages. The first transmission belt 301 can rotate under the control of the drive unit 4. When the first transmission belt 301 rotates to the point where its surface overlaps with the surface of the first conveyor line 1, the express delivery can be transported on the first conveyor line 1. When the first transmission belt 301 rotates to a certain angle, the express delivery on the first conveyor line 1 will move to the second conveyor line 2 through the reversing port 103, so that the express delivery can be transported on the second conveyor line 2. This solves the problem that when warehouse space and layout are limited, multiple sorting areas with different heights will appear. At this time, the use of a single express delivery sorting line can no longer meet the express delivery sorting problem.

[0034] It is worth noting that this solution includes a scanner, which is installed on the first conveyor line 1. The scanner is located between the input port 101 and the reversing port 103 of the first conveyor line 1. The function of the scanner is to identify the information of the express delivery passing through the scanner. Based on the information identified by the scanner, the rotation angle of the first transmission belt 301 is controlled so that the express delivery can be transported on the first conveyor line 1 or the second conveyor line 2.

[0035] As described in the above embodiments, the first transmission belt 301 rotates to a specific angle, enabling express packages located on the first conveyor line 1 to move to the second conveyor line 2. However, due to the varying heights of the express packages, there are instances where, after the first transmission belt 301 rotates to a specific angle, the distance between the first transmission belt 301 and the first conveyor line 1 is less than the height of the express package. This results in the express package being unable to move to the second conveyor line 2 through the gap between the first transmission belt 301 and the first conveyor line 1. Therefore, to address this problem, the sorting component 3 in this solution further includes a second transmission belt 302. The second transmission belt 302 is symmetrically arranged relative to the first transmission belt 301 at the other end of the switching port 103, and is hinged to one end of the first conveyor line 1. The hinge points of the first transmission belt 301 and the second transmission belt 302 are located at the two ends of the switching port 103, respectively. The drive unit 4 is hinged to the second transmission belt 302. The second transmission belt 302 and the first transmission belt 301 have the same rotation angle and opposite rotation directions. It should be noted that when the first transmission belt 301 and the second transmission belt 302 are not rotating, the first transmission belt 301 and the second transmission belt 302 together fill the switching port 103, and the surface height of the first transmission belt 301 and the surface height of the second transmission belt 302 are level, and the surface height of the first transmission belt 301 and the surface height of the second transmission belt 302 are equal to the surface height of the first conveyor line 1. Thus, the express can smoothly move from the input port 101 of the first conveyor line 1 to the output port 102 of the first conveyor line 1. When the drive unit 4 starts working, it will simultaneously drive the first transmission belt 301 and the second transmission belt 302 to rotate. The first transmission belt 301 will rotate towards the bottom of the first conveyor line 1, while the second transmission belt 302 will rotate towards the top of the first conveyor line 1. The rotation angles of the first transmission belt 301 and the second transmission belt 302 are the same. With this setting, when the first transmission belt 301 rotates to a specific angle, the gap between the first transmission belt 301 and the second transmission belt 302 will exceed the maximum height of the express delivery, making it easier for the express delivery to enter the second conveyor line 2 smoothly.

[0036] Specifically, the drive unit 4 of this solution includes a retaining rod 401 and a hinge unit. The retaining rod 401 is horizontally mounted on the top of the first conveyor line 1. The central axis of the retaining rod 401 is projected onto the surface of the first conveyor line 1 on the line of symmetry of the switching point 103, and the projection of the central axis of the retaining rod 401 onto the surface of the first conveyor line 1 is perpendicular to the transport direction of the first conveyor line 1. The hinge unit includes a hinge block 402 and two hinge rods 403. The center of the hinge block 402 is rotatably coaxially connected to the retaining rod 401. The two hinge rods 403 are located at both ends of the hinge block 402, and the two hinge rods 403 are respectively matched with the first transmission belt 301 and the second transmission belt 302. Any hinge rod Both ends of 403 are hinged to one end of the hinge block 402 and one end of the first transmission belt 301 or the second transmission belt 302, respectively. It should be noted that the central axis of the retaining rod 401, projected onto the lane change opening 103, lies on the line of symmetry between the first transmission belt 301 and the second transmission belt 302. The two hinge rods 403 are parallel to each other, and the hinge points of the two hinge rods 403 and the hinge block 402 are equidistant from the center of the hinge block 402. Furthermore, the distance between the hinge point of the hinge rod 403 and the corresponding hinge point of the first transmission belt 301 and the line of symmetry of the lane change opening 103 is equal to the distance between the hinge point of the other hinge rod 403 and the corresponding hinge point of the second transmission belt 302 and the line of symmetry of the lane change opening 103. It should be noted that when the hinge block 402 is in its initial state, it is horizontally positioned, both hinge rods 403 are vertically positioned, and the surfaces of the first transmission belt 301 and the second transmission belt 302 are flush. When the hinge block 402 rotates along the central axis of the retaining rod 401, the end of the hinge block 402 near the second transmission belt 302 is in a raised state, and the end of the hinge block 402 near the first transmission belt 301 is in a lowered state. Therefore, the second transmission belt 302 can rotate towards the top of the first conveyor line 1, and the first transmission belt 301 can rotate towards the bottom of the first conveyor line 1.

[0037] Specifically, the drive unit 4 of this solution also includes a drive motor 404, a drive block 405, and a drive rod 406. The drive motor 404 is mounted on top of the first conveyor line 1. The output end of the drive motor 404 is connected to one end of the drive block 405. The two ends of the drive rod 406 are respectively hinged to the other end of the drive block 405 and the end of the hinge block 402 near the second transmission belt 302. With this configuration, when the drive motor 404 rotates, it will drive the first transmission belt 301 and the second transmission belt 302 to rotate. It should be noted that when the drive motor 404 rotates half a turn, the first transmission belt 301 and the second transmission belt 302 complete rotation, and the gap between the first transmission belt 301 and the second transmission belt 302 reaches its maximum. When the drive motor 404 continues to rotate half a turn, the first transmission belt 301 and the second transmission belt 302 return to their original positions, and the surfaces of the first transmission belt 301 and the second transmission belt 302 are flush. It should also be noted that, in order to ensure that the drive block 405 and drive rod 406 do not have a "dead point" position during rotation, the initial angle of the drive block 405 and drive rod 406 is set at an angle, and when viewed along the rotation direction of the output end of the drive motor 404, the end of the drive block 405 closest to it and the drive rod 406 rotates towards the top.

[0038] It should also be noted that the minimum height of the first transmission belt 301 in this solution is higher than the setting height of the second conveyor line 2. This setting ensures that the express delivery on the first transmission belt 301 will fall smoothly onto the second conveyor line 2.

[0039] It is worth noting that the drive unit 4 in this solution cannot be replaced by the existing lifting structure. This is because the stroke of the motor rotation is faster than the stroke of the motor lifting. When there is a large volume of express deliveries, the working efficiency of the drive unit 4 in this solution is much greater than that of the lifting structure. Therefore, in the field of small and medium-sized express sorting, the lifting structure cannot replace the structure of the drive unit 4 in this solution.

[0040] As described in the above embodiment, when a package falls from the first conveyor belt 301 onto the second conveyor line 2, it possesses an initial velocity provided by the first conveyor belt 301 before falling onto the second conveyor line 2. Simultaneously, there is a height difference between the package and the first conveyor belt 301 as it falls onto the second conveyor line 2. The combined effect of the initial velocity and the height difference causes the package to tumble upon falling onto the second conveyor line 2. It should be noted that this device is specifically designed for sorting fragile packages. If a package tumbles during the sorting process, there is a possibility that the contents of the package may be damaged during the sorting process. To avoid this situation, the solution also includes a stabilizing component 5, which includes a stabilizing plate 501 and a stabilizing rod 502. The stabilizing plate 501 is disposed at the bottom of the second transmission belt 302. The two ends of the stabilizing rod 502 are respectively connected to the stabilizing plate 501 and the second transmission belt 302. The surface of the stabilizing plate 501 is parallel to the surface of the second transmission belt 302. When the first transmission belt 301 rotates towards the bottom, the end of the first transmission belt 301 away from its hinge point is separated from the stabilizing plate 501 by a certain distance, which is less than the length of the belt. It should be noted that after rotation, the end face of the stabilizing plate 501 and the surface of the first transmission belt 301 are on the same inclined plane. With the stabilizer plate 501 in place, when the first transmission belt 301 rotates, the end face of the stabilizer plate 501 is on the same plane as the surface of the first transmission belt 301, and one end of the first transmission belt 301 is separated from the stabilizer plate 501 by a certain distance, which is less than the length of the express delivery. This arrangement allows the express delivery to move from the first transmission belt 301 to the stabilizer plate 501, and during the movement of the express delivery on the stabilizer plate 501, the speed of the express delivery will gradually decrease to zero until the express delivery stops moving. Next, the first transmission belt 301 resets, and the second transmission belt 302 resets along with it. Since the inlet 201 of the second conveyor line 2 is located directly below the reversing inlet 103, after the second transmission belt 302 resets, the stabilizing plate 501 will also be located on the second conveyor line 2. At this time, as long as the express delivery is transported to the second conveyor line 2, the height difference and initial velocity of the express delivery when it moves from the first transmission belt 301 to the second conveyor line 2 can be eliminated, thus achieving the effect of the express delivery falling smoothly from the first transmission belt 301 onto the second conveyor line 2 and avoiding the express delivery from flipping over.

[0041] To achieve the aforementioned technical effects, the stabilizing component 5 of this solution further includes several rotating units. These rotating units are equally spaced on the stabilizing plate 501 along the transport direction of the second conveyor line 2. Each rotating unit includes several rotating beads 504 and a rotating rod 505. The rotating rod 505 is rotatably mounted on the stabilizing plate 501. The axial direction of the rotating rod 505 is projected onto the surface of the second conveyor line 2 and is perpendicular to the transport direction of the second conveyor line 2. The rotating beads 504 are coaxially mounted on the rotating rod 505 at equal intervals along the axial direction of the rotating rod 505. The top height of the rotating beads 504 is higher than the surface height of the stabilizing plate 501. First, it should be noted that since the stabilizing plate 501 is connected to the second transmission belt 302, the stabilizing plate 501, like the second transmission belt 302, has two states: the first state, in which the stabilizing plate 501 is in a horizontal state; and the second state, in which the stabilizing plate 501 is in a raised state. With this setup, when the stabilizer plate 501 is in an elevated state, the rotating bead 504 will not rotate. When the express delivery moves from the first transmission belt 301 onto the stabilizer plate 501, its speed on the stabilizer plate 501 will gradually decrease until it stops moving. After the second transmission belt 302 resets, the stabilizer plate 501 changes from an elevated state to a horizontal state. At this time, the rotating bead 504 resumes rotation, and the rotation direction of the rotating bead 504 is the same as the transport direction of the second conveyor line 2. This setup enables the rotating bead 504 to control the movement of the express delivery, moving it from the stabilizer plate 501 onto the second conveyor line 2.

[0042] Furthermore, to achieve the rotation of the rotating bead 504, the rotating unit of this solution also includes a connecting gear 506, a driving gear 507, and a driving ring 503. The connecting gear 506 is rotatably mounted on the side wall of the stabilizing plate 501 and is coaxially connected to the rotating rod 505. The driving gear 507 is rotatably mounted on the side wall of the stabilizing plate 501 and meshes with the connecting gear 506. The driving ring 503 is coaxially connected with the driving gear 507, and the diameter of the driving ring 503 is larger than the diameter of the driving gear 507. In addition, when the stabilizing plate 501 is in a horizontal state, the end face of the driving ring 503 is in a mating fit with the surface of the second conveyor line 2; when the stabilizing plate 501 is in an inclined state, the end face of the driving ring 503 is released from its mating fit with the surface of the second conveyor line 2. With this configuration, when the stabilizing plate 501 is tilted, the driving ring 503 releases its contact with the surface of the second conveyor line 2, preventing the rotating bead 504 from rotating. When the stabilizing plate 501 is horizontal, the driving ring 503 locks its contact with the surface of the second conveyor line 2, controlling the driving gear 507 to rotate. This, in turn, drives the connecting gear 506 to mesh and rotate, ultimately causing the rotating bead 504 to rotate. Furthermore, due to the cooperation between the connecting gear 506 and the driving gear 507, the transport direction of the rotating bead 504 for the express delivery is the same as the transport direction of the express delivery on the second conveyor line 2.

[0043] It is worth noting that the friction between the rotating rod 505 and the stable plate 501 in this design is greater than the friction between the express delivery and the rotating ball 504. This design ensures that when the express delivery moves onto the stable plate 501, it will not cause the rotating ball 504 to move.

[0044] As described in the above embodiments, in order to prevent the express delivery from sliding off the stable plate 501 due to inertia while moving to the stable plate 501, this solution also provides a blocking unit 6. The blocking unit 6 includes a blocking block 601, which is a flexible component. The blocking block 601 is located at the top of the end of the stable plate 501 away from the first transmission belt 301. By providing the blocking block 601, when the express delivery moves to the stable plate 501, it will continue to move on the stable plate 501 along the conveying direction of the first transmission belt 301 due to inertia. If the express delivery cannot reduce its speed to zero while sliding on the stable plate 501, it will collide with the blocking block 601. Since the blocking block 601 in this solution is a flexible component, it can stop the express delivery from sliding on the stable plate 501 without damage.

[0045] However, it should also be noted that when the transport direction of the second conveyor line 2 is not the same as that of the first conveyor line 1, after the stabilizer plate 501 is reset, the rotating bead 504 will drive the express delivery to move out of the stabilizer plate 501; if the transport direction of the second conveyor line 2 is the same as that of the first conveyor line 1, due to the presence of the blocking block 601, even after the stabilizer plate 501 is reset, the express delivery will still be unable to move out of the stabilizer plate 501 due to the obstruction of the blocking block 601. Based on this, in order to solve the above problems, the blocking unit 6 of this solution also includes a limiting rod 602, a limiting spring 603, a pressing rod 604, and a rotating rod 605. The top of the blocking block 601 is hinged to the side wall of the stabilizing plate 501. The stabilizing plate 501 has a limiting slot 5011, a rotating slot 5012, and a pressing slot 5013. The rotating slot 5012 is located inside the stabilizing plate 501. The limiting slot 5011 is located on the top surface inside the stabilizing plate 501. The pressing slot 5013 is located on the bottom surface inside the stabilizing plate 501. The rotating slot 5012 communicates with the limiting slot 5011 and the pressing slot 5013 respectively. The rotating rod 605 is located inside the rotating slot 5012. The middle end of the rotating rod 605 is hinged to the interior of the stabilizing plate 501. The limiting rod 602 is slidably located inside the limiting slot 5011. The horizontal... The cross-sectional shape is the same as that of the limiting rod 602; the blocking unit 6 also includes a first sliding block 606 and a second sliding block 607. The end face of the rotating rod 605 is provided with a sliding groove 6051. The setting direction of the sliding groove 6051 is parallel to the central axis direction of the rotating rod 605. The first sliding block 606 and the second sliding block 607 are slidably disposed at both ends of the sliding groove 6051. The bottom end of the limiting rod 602 is hinged to the first sliding block 606. Similarly, the pressing rod 604 is slidably disposed in the pressing groove 5013. The cross-sectional shape of the pressing groove 5013 is the same as that of the pressing rod 604. The top of the pressing rod 604 is hinged to the second sliding block 607. The limiting spring 603 is disposed in the rotating groove 5012. The two ends of the limiting spring 603 are respectively connected to the interior of the stabilizing plate 501 and one end of the rotating rod 605. Furthermore, looking along the transport direction of the first transmission belt 301, the limiting rod 602 is positioned in front of the blocking block 601, and the limiting rod 602 can lock or release its restraining relationship with the blocking block 601. It is also worth noting that the length of the pressing rod 604 extending beyond the stabilizing plate 501 is greater than the distance between the stabilizing plate 501 and the surface of the second conveyor line 2 when the stabilizing plate 501 is in a horizontal state.With this configuration, when the stabilizer plate 501 is in the raised state, due to the force of the limiting spring 603, the rotating rod 605 is tilted, causing the top of the limiting rod 602 to extend beyond the stabilizer plate 501. This restricts the rotation of the blocking block 601, ensuring that the express delivery stops on the stabilizer plate 501. During the reset of the stabilizer plate 501 towards a horizontal state, the distance between the stabilizer plate 501 and the second conveyor line 2 decreases, causing the pressing rod 604 to first contact the surface of the second conveyor line 2, thereby controlling the pressing rod 604 to move inwards towards the stabilizer plate 501. This causes the rotating rod 605 to rotate, which in turn drives the limiting rod 602 to move towards the interior of the stabilizing plate 501 until the stabilizing plate 501 returns to its horizontal state. At this point, the limiting rod 602 retracts completely into the stabilizing plate 501, thus releasing the limiting rod 602 from its restrictive relationship with the blocking block 601. When the express delivery moves, it drives the blocking block 601 to rotate, allowing the express delivery to move smoothly from the stabilizing plate 501 to the second conveyor line 2. After the blocking block 601 releases its abutment from the express delivery, it returns to its original position due to gravity.

[0046] It should be noted that the bottom of the pressing rod 604 in this solution is an arc structure, which facilitates the pressing action of the pressing rod 604 with the second conveyor line 2.

[0047] It should also be noted that the blocking block 601 in this solution has a reset mechanism; when the express delivery moves out of the stabilizing plate 501, the blocking block 601 returns to its original position. Furthermore, the express delivery sorted by this device consists of fragile, small to medium-sized goods, which have a certain weight, thus enabling the blocking block 601 with its reset mechanism to be pushed.
