Description

Technical Field

[0001] This invention relates to the field of logistics sorting technology, and in particular to a modular belt sorting machine. Background Technology

[0002] In the logistics industry, efficient and accurate sorting is crucial for improving logistics efficiency. One common structure in widely used logistics sorting machines features a circular conveyor belt with sorting rollers mounted on it. To facilitate the operation of these rollers, a swinging wheel is installed on the frame. The axle of the sorting roller is perpendicular to the conveyor belt's direction of travel, i.e., parallel to the width of the sorting machine. Normally, when the axle of the swing wheel is perpendicular to the axle of the sorting roller, the two wheels do not contact each other, and the sorting roller remains stationary and does not rotate. However, when the swing wheel rotates to a certain angle and comes into contact with the sorting roller, the relative motion between them causes the sorting roller to rotate, thus enabling it to perform its sorting function. This design, to a certain extent, meets the basic requirements of logistics sorting.

[0003] However, existing fixed-position swing wheels exhibit significant drawbacks during actual operation. When the swing wheel oscillates, interference frequently occurs between it and the sorting wheel. This interference not only causes additional friction and collisions between the sorting wheel and the swing wheel during operation, easily damaging them, but also affects the stability of the equipment's normal operation. Frequent malfunctions and repairs increase the operating costs of logistics companies, significantly impacting the lifespan of the sorting equipment and hindering the efficient and sustainable development of the logistics industry. Based on the problems existing in the prior art, this paper proposes a modular belt sorting machine to overcome the shortcomings of existing swing wheel configurations in logistics sorting machines. Summary of the Invention

[0004] The purpose of this invention is to provide a modular belt sorting machine to solve the problems pointed out in the background art.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A modular belt sorting machine includes a frame, a power unit, sorting slots, a centering motion component, multiple sorting units, and a conveyor belt. The sorting slots are located on the side of the frame. The power unit, the centering motion component, and the multiple sorting units are mounted on the frame. The conveyor belt surrounds the frame. Each sorting unit includes a drive motor, a drive shaft, a lower base plate, a middle floating plate, a rising top plate, a lifting cam, a lateral cam, a vertical lifting plate, a horizontal follower plate, and a swing wheel assembly. The drive motor and drive shaft are mounted below the lower base plate, and the drive shaft is connected to the drive motor. The middle floating plate and the rising top plate are located above the lower base plate, and the rising top plate is located above the middle floating plate. The lifting cam and the lateral cam are mounted on the drive shaft and rotate synchronously with the drive shaft. The vertical lifting plate is connected to the rising top plate. The horizontal follower plate is connected to the intermediate floating plate and is used to drive the intermediate floating plate to move horizontally. The intermediate floating plate is provided with a balance wheel drive component. The balance wheel assembly includes multiple balance wheel units. Each balance wheel unit is provided with a balance wheel driven component that cooperates with the balance wheel drive component. The balance wheel unit passes through the rising top plate and rises and falls with the rising top plate. The vertical lifting plate is provided with a transverse elongated hole, and the lifting cam is provided in the transverse elongated hole. The horizontal follower plate is provided with a vertical elongated hole, and the transverse cam is provided in the vertical elongated hole. By the cooperation of the transverse cam and the lifting cam with the vertical elongated hole and the transverse elongated hole, respectively, during one lifting action, the swinging motion of the balance wheel unit presents a fast-then-slow pattern, while the rising motion presents a slow-then-fast pattern.

[0007] In a preferred embodiment, the transverse cam includes a cam body and a cam sleeve. The inner wall of the cam sleeve is provided with a limiting groove, and the cam body is provided with a limiting strip. The cam sleeve is sleeved on the cam body, and the limiting strip cooperates with the limiting groove. The cam sleeve is made of rubber material.

[0008] In a preferred embodiment, a lifting guide rod is further included. The lower base plate is provided with a lifting guide hole, the lifting guide rod passes through the lifting guide hole, and is connected to the rising top plate.

[0009] In a preferred embodiment, two of each of the vertical lifting plate, horizontal follower plate, lifting cam, and lateral cam are provided.

[0010] In a preferred embodiment, the balance wheel support includes a balance wheel shaft, a balance wheel bracket, and a balance wheel body, wherein the balance wheel shaft is connected to the balance wheel bracket, and the balance wheel body is disposed on the balance wheel bracket.

[0011] In a preferred embodiment, the conveyor belt includes multiple connecting units, each connecting unit including a plate and multiple sorting wheels. The plate has multiple mounting openings, and the sorting wheels are installed in the mounting openings. The multiple mounting openings are arranged in a straight line. The plate has a first connecting member on one side and a second connecting member on the other side. The first connecting member and the second connecting member of adjacent connecting units are connected.

[0012] In a preferred embodiment, the first connection includes a plurality of first connecting plates and a connecting shaft, and the second connecting member includes a plurality of second connecting plates. The first connecting member and the second connecting member are connected to each other, and the second connecting plate is inserted into the gap between two adjacent first connecting plates. The connecting shaft passes through the first connecting plate and the second connecting plate to form the annular conveyor belt.

[0013] In a preferred embodiment, the balance wheel drive component is configured as a rack, and the balance wheel driven component is configured as a gear.

[0014] In a preferred embodiment, the plurality of balance wheel units are arranged in multiple rows, and the number of racks is the same as the number of rows of balance wheel units, with each rack controlling the oscillation of one row of balance wheel units.

[0015] In a preferred embodiment, the drive motor and the drive shaft are connected by a synchronous belt.

[0016] Compared with the prior art, the modular belt sorting machine of the present invention has a frame for support during operation, a power component for driving the conveyor belt to move in a circular motion, which can be a motor, a sorting slot for receiving sorted goods, a centering action component for centering the goods, and a conveyor belt for conveying and sorting.

[0017] The drive motor, the power source controlling the entire sorting unit, is installed below the lower base plate and connected to the drive shaft. The drive shaft drives the lifting cam and the transverse cam to rotate synchronously. The vertical lifting plate is connected to the rising top plate, and the movement of the lifting cam in the transverse elongated hole drives the rising top plate to move up and down. The horizontal follower plate is connected to the intermediate floating plate, and the rotation of the transverse cam in the vertical elongated hole realizes the horizontal movement of the intermediate floating plate. The swing wheel assembly contains multiple swing wheel units, which cooperate with the intermediate floating plate through the swing wheel drive component and the swing wheel driven component. It can rise and fall with the rising top plate and swing under the action of the intermediate floating plate.

[0018] During the sorting process, when sorting is not required, the swing wheel assembly is in a low position, and the conveyor belt does not perform sorting operations. When sorting is required, the drive motor starts, the drive shaft rotates, and the lifting cam and the lateral cam rotate accordingly. The lifting cam drives the vertical lifting plate, causing the upper plate to rise, which in turn causes the swing wheel assembly to rise; simultaneously, the lateral cam drives the horizontal follower plate, causing the middle floating plate to move laterally, which in turn causes the swing wheel unit to swing. When the swing wheel unit rises to a certain position and contacts the conveyor belt, the conveyor belt begins to perform sorting operations. After the operation is completed, the drive motor reverses, and through the same control principle, the upper plate and the middle floating plate are reset, the swing wheel assembly returns to the low position, and the conveyor belt stops sorting.

[0019] This structural design brings significant technical benefits. First, it effectively solves the interference problem between the swing wheel and sorting wheel in existing technologies, reducing equipment wear and tear and malfunctions, and extending the equipment's lifespan. Second, through precise mechanical transmission and control, it achieves efficient and accurate execution of the sorting action, improving logistics sorting efficiency. Most importantly, by ensuring that the swing wheel's oscillation is initially fast and then slows down, while the upward movement is initially slow and then fast, the oscillation is essentially completed at the end of the upward movement. This ensures that the oscillation is largely finished before the swing wheel contacts the sorting wheel, avoiding the interference problem between the swing wheel and sorting wheel found in existing technologies. Furthermore, the component's rational structural design, coordinated operation of all parts, and high stability reduce the operating costs of logistics companies, providing strong support for the efficient and sustainable development of the logistics industry.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0031] like Figures 1 to 8As shown, a modular belt sorting machine includes a frame 25, a power unit, sorting slots 26, a centering motion component, multiple sorting units, and a conveyor belt 24. The sorting slots 26 are located on the side of the frame. The power unit, the centering motion component, and the multiple sorting units are mounted on the frame 25. The conveyor belt 24 surrounds the frame 25. Each sorting unit includes a drive motor 1, a drive shaft 2, a lower base plate 3, a middle floating plate 5, a rising top plate 6, a lifting cam 7, a transverse cam 8, a vertical lifting plate 9, a horizontal follower plate 11, and a swing wheel assembly. The drive motor 1 and drive shaft 2 are mounted below the lower base plate 3, and the drive shaft 2 is connected to the drive motor 1. The middle floating plate 5 and the rising top plate 6 are located above the lower base plate 3, and the rising top plate 6 is located above the middle floating plate 5. The lifting cam 7 and the transverse cam 8 are mounted on the drive shaft 2 and rotate synchronously with the drive shaft 2. The vertical lifting plate 9 is connected to the horizontal follower plate 11. The rising top plate 6 is used to drive the rising top plate 6 to move up and down. The horizontal follower plate 11 is connected to the intermediate floating plate 5 and is used to drive the intermediate floating plate 5 to move horizontally. The intermediate floating plate 5 is provided with a balance wheel drive component. The balance wheel assembly includes multiple balance wheel units. Each balance wheel unit is provided with a balance wheel driven component that cooperates with the balance wheel drive component. The balance wheel unit passes through the rising top plate 6 and rises and falls with the rising top plate 6. The vertical lifting plate 9 is provided with a horizontal elongated hole 10. The lifting cam 7 is provided in the horizontal elongated hole 10. The horizontal follower plate 11 is provided with a vertical elongated hole 12. The transverse cam 8 is provided in the vertical elongated hole 12. By cooperating with the vertical elongated hole 12 and the horizontal elongated hole 10 respectively, the swing motion of the balance wheel unit is fast at first and then slow down during a lifting action, while the rising action is slow at first and then fast.

[0032] In this embodiment, a modular belt sorting machine is used for operation. The frame 25 is used for support, the power component is used to drive the conveyor belt 24 so that the conveyor belt 24 moves in a circular motion. The power component can be a motor. The sorting slots 26 are used to receive the sorted goods, the centering action component is used to center the goods, and the conveyor belt 24 is used to transport and sort the goods.

[0033] The drive motor 1 is the power source controlling the entire sorting unit. It is installed below the lower base plate 3 and connected to the drive shaft 2. The drive shaft 2 drives the lifting cam 7 and the transverse cam 8 to rotate synchronously. The vertical lifting plate 9 is connected to the rising top plate 6. Through the movement of the lifting cam 7 in the transverse elongated hole 10, the rising top plate 6 is driven to move up and down. The horizontal follower plate 11 is connected to the intermediate floating plate 5. The horizontal movement of the intermediate floating plate 5 is achieved by the rotation of the transverse cam 8 in the vertical elongated hole 12. The swing wheel assembly contains multiple swing wheel units. Through the swing wheel drive component and the swing wheel driven component, it cooperates with the intermediate floating plate 5 and can rise and fall with the rise and fall of the rising top plate 6, and swing under the action of the intermediate floating plate 5.

[0034] During the sorting process, when sorting is not required, the swing wheel assembly is in a low position, and the conveyor belt 24 does not perform sorting. When sorting is required, the drive motor 1 starts, the drive shaft 2 rotates, and the lifting cam 7 and the lateral cam 8 rotate accordingly. The lifting cam 7 drives the vertical lifting plate 9, causing the rising top plate 6 to rise, which in turn causes the swing wheel assembly to rise; at the same time, the lateral cam 8 drives the horizontal follower plate 11, causing the intermediate floating plate 5 to move laterally, which in turn causes the swing wheel unit to swing. When the swing wheel unit rises to a certain position and contacts the conveyor belt 24, the conveyor belt 24 begins to perform sorting. After the operation is completed, the drive motor 1 reverses, and through the same control principle, the rising top plate 6 and the intermediate floating plate 5 are reset, the swing wheel assembly returns to the low position, and the conveyor belt 24 stops sorting.

[0035] This structural design brings significant technical benefits. First, it effectively solves the interference problem between the swing wheel and sorting wheel 14 in existing technologies, reducing equipment wear and malfunctions and extending the equipment's lifespan. Second, through precise mechanical transmission and control, it achieves efficient and accurate execution of the sorting action, improving logistics sorting efficiency. Most importantly, by ensuring that the swing wheel's oscillation is initially fast and then slows down, while the upward movement is initially slow and then fast, the oscillation is essentially completed at the end of the upward movement. This ensures that the oscillation is largely finished before the swing wheel contacts the sorting wheel 14, avoiding the interference problem between the swing wheel and sorting wheel 14 found in existing technologies. Furthermore, the component's rational structural design, coordinated operation of all parts, and high stability reduce the operating costs of logistics companies, providing strong support for the efficient and sustainable development of the logistics industry.

[0036] Regarding the question of how to achieve the completion time of the action between the transverse cam 18 and the lifting cam 17, it is achieved by setting the cooperation relationship between the transverse cam 8 and the vertical elongated hole 12, and the cooperation relationship between the lifting cam 7 and the transverse elongated hole 10. Those skilled in the art can make this shape setting.

[0037] The "one lifting action process" refers to the process of the lifting top plate 6 rising once, which is also the process of the balance wheel assembly rising once.

[0038] To adjust the swing amplitude, the transverse cam 8 includes a cam body 27 and a cam sleeve 28. The inner wall of the cam sleeve 28 has a limiting groove 29, and the cam body 27 has a limiting strip. The cam sleeve 28 is fitted onto the cam body 27, and the limiting strip cooperates with the limiting groove 29. The cam sleeve 28 is made of rubber. By replacing the cam sleeve 28, the eccentric position of the transverse cam 8 can be adjusted. By adjusting the eccentric position, different swing amplitudes of the swing unit can be adjusted.

[0039] The material of the cam sleeve 28 is not limited to rubber. Any material that facilitates assembly and allows the cam sleeve 28 and the cam body 27 to be joined can be used, but at the same time, it must ensure a certain structural strength.

[0040] Regarding how the cam sleeve 28 is set to achieve the adjustment of the eccentric position: Since the cam sleeve 28 is fitted on the cam body 29, the outer contour shape of the transverse cam 8 is determined by the cam sleeve 28. By setting the cam sleeve 28 to different shapes, the eccentric position can be adjusted, and the shape of the transverse cam 9 can also be adjusted.

[0041] To facilitate the installation of the cam sleeve 28, a docking interface can be provided on the cam sleeve 28, and a connection can be achieved by connecting buckles. Thus, the cam sleeve 28 can be fitted onto the cam body 27 by opening the docking interface.

[0042] In this embodiment, both the transverse elongated hole 10 and the vertical elongated hole 12 are set as elongated oval holes, and both the lifting cam 7 and the transverse cam 8 are set as circular and are eccentrically set on the drive shaft 2. When the rising top plate 6 is at its lowest position, the point on the circumference of the lifting cam 7 and the transverse cam 8 that is farthest from the drive shaft is at its lowest position.

[0043] Regarding the cooperation between the transverse elongated hole 10 and the lifting cam 7, and the cooperation between the vertical elongated hole 12 and the transverse shifting cam 8, more specifically: both the transverse elongated hole 10 and the vertical elongated hole 12 are set as elongated holes, that is, elongated holes with circular ends, and the two ends are connected by a straight line segment. Both the lifting cam 7 and the transverse shifting cam 8 are set as circular and are eccentrically set on the drive shaft 2. In the non-sorting state, that is, when the rising top plate 6 is at its lowest position, the point on the circumference of the lifting cam 7 and the transverse shifting cam 8 that is farthest from the drive shaft is at its lowest position, that is, the longest swing arm is in a vertical state. Through this structural setting, the setting objective of this case is achieved.

[0044] In order to guide the rising top plate 6 during the lifting process, a module belt sorting machine in this embodiment also includes a lifting guide rod 17. The lower base plate 3 is provided with a lifting guide hole 4. The lifting guide rod 17 passes through the lifting guide hole 4 and is connected to the rising top plate 6. Multiple lifting guide rods 17 are provided.

[0045] In order to achieve stable support for the intermediate floating plate 5 and make the overall structure stable, two of each of the vertical lifting plate 9, horizontal follower plate 11, lifting cam 7 and transverse cam 8 are provided and are symmetrically arranged with respect to the center line of the lower base plate 3 to achieve symmetrical arrangement of the structure.

[0046] In this embodiment, the balance wheel support 19 includes a balance wheel shaft 18, a balance wheel support 19, and a balance wheel body 20. The balance wheel shaft 18 is connected to the balance wheel support 19, and the balance wheel body 20 is disposed on the balance wheel support 19.

[0047] The conveyor belt 24 includes multiple connecting units, each including a plate 13 and multiple sorting wheels 14. The plate 13 has multiple mounting openings into which the sorting wheels 14 are mounted. The mounting openings are arranged in a straight line. The plate 13 has a first connecting member on one side and a second connecting member on the other. The first and second connecting members of adjacent connecting units are connected to form a ring-shaped conveyor belt 24. The multiple connecting units are connected to form a whole. During sorting, the swing wheel contacts the sorting wheels 14, thereby executing the sorting action.

[0048] Specifically, the first connection includes multiple first connecting plates 15 and a connecting shaft (not shown in the figure), and the second connecting member includes multiple second connecting plates 16. The first and second connecting members are mutually connected, with the second connecting plate 16 inserted into the gap between two adjacent first connecting plates 15, and the connecting shaft passing through the first connecting plate 15 and the second connecting plate 16. This structural arrangement enables rotational connection between adjacent connecting units.

[0049] Furthermore, the balance wheel driving component is configured as a rack 22, and the balance wheel driven component is configured as a gear 21. The oscillation of the balance wheel unit is realized through the cooperation of the gear 21 and the rack 22.

[0050] Specifically, the multiple balance wheel units are arranged in multiple rows, and the number of racks 22 is the same as the number of rows of the balance wheel units. Each rack 22 controls the oscillation of one row of balance wheel units. Through the movement of the intermediate floating plate 5, the synchronous movement of multiple racks 22 is achieved, thereby realizing the synchronous movement of multiple balance wheel units.

[0051] To achieve precise control, the drive motor 1 and the drive shaft 2 are connected by a synchronous belt 23.
