Description

Technical Field

[0001] This utility model relates to the field of logistics sorting equipment technology, and in particular to a flip-type sorting grid device and a cross-belt sorting system. Background Technology

[0002] Currently, cross-belt sorters are widely used in automated sorting equipment in the logistics, e-commerce, and express delivery sectors. They are mostly circular or linear structures. Items move along the main line of the sorter via transport trolleys. Multiple exit slots are distributed on both sides of the sorter. When an item reaches its corresponding exit, the transport trolley rotates its belt to generate power, moving the item out of the main sorting line and into the unloading (slot) on either side, completing the sorting process. The unloading (slot) system is the end-point equipment of the sorting system, and its function is to temporarily store items fed in by the sorting host.

[0003] Because sorting machines have multiple exit slots, and the height and width of each individual exit slot are currently fixed, in order to ensure that goods are smoothly sorted to the slots, the width of the sorting machine slots is often made very large, resulting in a reduction in the number of slots and the number of sorting paths. At the same time, it will increase the length of the sorting machine's main line, which will inevitably increase the manufacturing cost of the equipment. On the other hand, the floor space occupied by the equipment will also increase.

[0004] A current Chinese patent (application number: CN202420127454.4) discloses a sorting device for unloading parts and its cross-belt sorting machine. When the flipping base plate of the flipping assembly flips down to its lower limit position, the flipping assembly connects to the lower end tray; when the flipping base plate of the flipping assembly flips up to its upper limit position, the flipping assembly connects to the upper end tray. The problem is that the tilting stability of the flipping assembly relies solely on its own linkage mechanism and linear drive mechanism. If the driving force of the linear drive mechanism is insufficient, and the material is heavy, the flipping base plate is highly likely to lose stability. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a flip-type sorting grid device and a cross-belt sorting system, which adopts a two-in-one grid so that one grid forms two switchable material channels leading to different sorting destinations. More importantly, the driving force requirement of the flipping drive device is relatively low. In addition, it can reduce the length of the sorting machine main line of the cross-belt sorting system, reduce the floor space of the cross-belt sorting system, and reduce the cost of the cross-belt sorting system.

[0006] To solve the above-mentioned technical problems, this utility model provides a flip-type sorting grid device, comprising:

[0007] Support frame;

[0008] The sorting chute is located on the support frame, and the two ends of the sorting chute along its own falling direction are the inlet port and the outlet port, respectively.

[0009] A layered chute is mounted on a support frame. The two ends of the layered chute along its own dropping direction are a receiving port and a blocking port, respectively. The receiving port of the layered chute is connected to the discharge port of the sorting chute. The layered chute includes a first compartment and a second compartment located above the first compartment. The bottom of the first compartment is connected to the bottom of the sorting chute.

[0010] The flip plate assembly includes a flip plate and a rotating shaft. The flip plate is hinged to the sorting chute via the rotating shaft near the edge of the layered chute and is adjacent to the bottom of the second compartment slot.

[0011] A flipping drive device includes a linkage mechanism and a driver. The driver is located on a support frame and is connected to the flipping plate through the linkage mechanism to make the flipping plate swing up and down around the rotation axis within a preset angle range.

[0012] When the flip plate swings upward to its upper limit position, the material fed into the sorting chute slides into the first compartment slot.

[0013] When the tilting plate swings downwards to its lower limit position, the edge of the tilting plate away from the layered chute abuts against the bottom of the sorting chute, and the material fed into the sorting chute slides into the second compartment through the tilting plate.

[0014] Furthermore, the bottom of the sorting chute includes a first bottom plate and a second bottom plate. The inclination angle of the second bottom plate relative to the horizontal plane is greater than that of the first bottom plate relative to the horizontal plane. The two sides of the second bottom plate along its own material dropping direction are respectively connected to the bottom of the first bottom plate and the bottom of the first grid slot.

[0015] Furthermore, the linkage mechanism includes a swing frame and a connecting rod. The swing frame is connected to the rotating shaft and to the flip plate via a connecting pin. The connecting rod is connected to the swing frame and the driver respectively.

[0016] Furthermore, the sorting chute has an arc-shaped clearance hole on its wall that allows the connecting pin to pass through.

[0017] Furthermore, the swing frame is A-shaped, with a top and two feet. The top is connected to a connecting pin, one foot is connected to a pivot, and the other foot is connected to a connecting rod.

[0018] Furthermore, the actuator is a telescopic cylinder.

[0019] Furthermore, the edge of the flip plate away from the layered slide has an anti-collision flip edge.

[0020] Furthermore, the sorting chute is provided with a seated outer spherical ball bearing on its chute wall, which allows for the installation of a rotating shaft.

[0021] This utility model also provides a cross-belt sorting system, including:

[0022] Sorting machine main line;

[0023] Transport trolleys are located on the main line of the sorting machine;

[0024] The flip-type sorting grid device has its sorting chute's feed port tilted towards the conveying direction of the sorting machine's main line.

[0025] As described above, the flip-plate sorting grid device and cross-belt sorting system of this utility model have the following beneficial effects: Compared with the unloading grid device disclosed in the existing Chinese patent (application number: CN202420127454.4), the sorting principle of the flip-plate sorting grid device of this utility model is completely different. When the flip plate swings downward to the lower limit position, the edge of the flip plate away from the layered chute abuts against the bottom of the sorting chute. The material fed into the sorting chute slides into the second grid slot through the flip plate and then flows to a destination. At this time, the bottom of the sorting chute and the rotating shaft can jointly support the flip plate, and the flip plate can bear heavier materials, greatly improving the tilting stability of the flip plate. When the flip plate swings upward to the upper limit position, the material fed into the sorting chute slides into the first grid slot and then flows to another destination. At this time, the flip plate does not need to bear the weight of the material. Therefore, the flip-type sorting grid device of this utility model adopts a two-in-one grid, so that one grid forms two switchable material channels, which lead to different sorting destinations respectively. More importantly, the driving force requirement of the flip drive device is relatively low. In addition, it can reduce the length of the sorting machine main line of the cross belt sorting system, reduce the floor space of the cross belt sorting system, and reduce the cost of the cross belt sorting system.

[0050] 6 Sorting Machine Main Line Detailed Implementation

[0051] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0052] It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings of this specification are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the content disclosed herein. They are not intended to limit the implementation conditions of this utility model and therefore have no substantial technical significance.

Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model.

[0053] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, this utility model provides a flip-type sorting grid device, comprising:

[0054] Support frame 1;

[0055] Sorting chute 2 is mounted on support frame 1. The two ends of sorting chute 2 along its own falling direction are the feeding port and the discharging port, respectively.

[0056] The layered chute 3 is mounted on the support frame 1. The two ends of the layered chute 3 along its own falling direction are a receiving port and a blocking port, respectively. The receiving port of the layered chute 3 is connected to the discharge port of the sorting chute 2. The layered chute 3 includes a first grid groove 31 and a second grid groove 32 located above the first grid groove 31. The bottom of the first grid groove 31 is connected to the bottom of the sorting chute 2.

[0057] Flip plate assembly 4 includes a flip plate 41 and a rotating shaft 42. The flip plate 41 is hinged to the sorting chute 2 near the edge of the layered chute 3 via the rotating shaft 42 and is closely connected to the bottom of the second compartment 32.

[0058] The flipping drive device 5 includes a linkage mechanism 51 and a driver 52. The driver 52 is located on the support frame 1 and is connected to the flipping plate 41 through the linkage mechanism 51 so that the flipping plate 41 swings up and down around the rotating shaft 42 within a preset angle range.

[0059] When the flip plate 41 swings upward to the upper limit position, the material fed into the sorting chute 2 slides into the first compartment 31.

[0060] When the tilting plate 41 swings downward to the lower limit position, the edge of the tilting plate 41 away from the layered chute 3 abuts against the bottom of the sorting chute 2, and the material fed into the sorting chute 2 slides into the second compartment 32 through the tilting plate 41.

[0061] In the lower compartment device disclosed in the existing Chinese patent (application number: CN202420127454.4), when the flip plate of the flip assembly flips down to the lower limit position, the flip plate is connected to the lower end support plate, and the flip plate needs to bear the weight of the material; when the flip plate of the flip assembly flips up to the upper limit position, the flip plate is connected to the upper end support plate, and the flip plate also needs to bear the weight of the material.

[0062] Compared to the sorting device disclosed in the existing Chinese patent (application number: CN202420127454.4), the sorting principle of the flip-plate sorting device of this utility model is completely different. When the flip plate 41 swings downward to its lower limit position, the edge of the flip plate 41 away from the layered chute 3 abuts against the bottom of the sorting chute 2. The material fed into the sorting chute 2 slides into the second sorting slot 32 through the flip plate 41 and then flows to a destination. At this time, the bottom of the sorting chute and the rotating shaft can jointly support the flip plate, and the flip plate can bear heavier materials, greatly improving the tilting stability of the flip plate. When the flip plate 41 swings upward to its upper limit position, the material fed into the sorting chute 2 slides into the first sorting slot 31 and then flows to another destination. At this time, the flip plate does not need to bear the weight of the material.

[0063] Therefore, the flip-type sorting grid device of this utility model adopts a two-in-one grid, so that one grid forms two switchable material channels, which lead to different sorting destinations respectively. More importantly, the driving force requirement of the flip drive device is relatively low. In addition, it can reduce the length of the sorting machine main line of the cross belt sorting system, reduce the floor space of the cross belt sorting system, and reduce the cost of the cross belt sorting system.

[0064] Furthermore, in order to facilitate the material to slide into the first or second compartment slot when the flip plate is switched to the lower or upper limit position, the bottom of the sorting chute 2 includes a first bottom plate 21 and a second bottom plate 22. The inclination angle of the second bottom plate 22 relative to the horizontal plane is greater than the inclination angle of the first bottom plate 21 relative to the horizontal plane. The two sides of the second bottom plate 22 along its own material dropping direction are respectively connected to the bottom of the first bottom plate 21 and the bottom of the first compartment slot 31.

[0065] Furthermore, to facilitate the up-and-down swinging of the flip plate, the linkage mechanism 51 includes a swing frame 511 and a connecting rod 512. The swing frame 511 is connected to the rotating shaft 42 and is also connected to the flip plate 41 via a connecting pin 513. The connecting rod 512 is connected to both the swing frame 511 and the driver 52. The swing frame 511 swings around the rotating shaft 42, and the swing frame 511 drives the flip plate 41 via the connecting pin 513.

[0066] Furthermore, in order to avoid motion interference between the connecting pin 513 and the sorting chute 2, the wall of the sorting chute 2 is provided with an arc-shaped clearance hole 23 that allows the connecting pin 513 to pass through.

[0067] Furthermore, to simplify the structure of the swing frame 511, the swing frame 511 is A-shaped, with a top and two feet. The top is connected to the connecting pin 513, one foot is connected to the rotating shaft 42, and the other foot is connected to the connecting rod 512.

[0068] Furthermore, the actuator 52 is a telescopic cylinder, such as a rod-mounted electric cylinder. Power is transmitted through the rod-mounted electric cylinder to drive the linkage mechanism, causing the tilting plate to tilt up and down, thereby achieving the material channel switching action between the first and second compartment slots.

[0069] Furthermore, to prevent materials from being damaged by the edge of the flip plate 41, the edge of the flip plate 41 away from the layered chute 3 has an anti-collision flip edge 411.

[0070] Furthermore, the sorting chute 2 is provided with a seated outer spherical ball bearing 24, such as a diamond-shaped seated outer spherical ball bearing, on the chute wall to allow the installation of the rotating shaft 42. By providing the diamond-shaped seated outer spherical ball bearing between the linkage mechanism and the flip plate assembly, during use, the flip plate is connected to the linkage mechanism via the rotating shaft, while the linkage mechanism and the flip plate are separated and do not directly contact each other. This greatly reduces friction loss and surface loss, extends the service life of the rotating shaft, and improves rotation smoothness.

[0071] This utility model also provides a cross-belt sorting system, including:

[0072] Sorting machine main line 6;

[0073] The transport trolley is located on the main line 6 of the sorting machine;

[0074] The flip-type sorting grid device has its sorting chute 2 with its inlet port tilted towards the conveying direction of the main line 6 of the sorting machine. The number of flip-type sorting grid devices can be two or more.

[0075] This reduces the length of the main sorting line in the cross-belt sorting system, reduces the floor space occupied by the cross-belt sorting system, and reduces the cost of the cross-belt sorting system.

[0076] In summary, this utility model's flip-type sorting grid device and cross-belt sorting system employ a two-in-one grid, allowing one grid to form two switchable material channels leading to different sorting destinations. More importantly, it requires less driving force from the flipping drive device. Furthermore, it reduces the length of the main sorting line in the cross-belt sorting system, decreases the floor space occupied by the system, and lowers its cost. Therefore, this utility model effectively overcomes the various shortcomings of existing technologies and possesses high industrial applicability.

[0077] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
