Description

Technical Field

[0001] The present invention relates to the technical field of logistics sorting, and in particular to a modular belt sorting machine. Background Art

[0002] In the logistics industry, efficient and accurate sorting is essential to improving logistics efficiency. One of the common structures of the currently widely used logistics sorting machines is that the conveyor belt is set in a ring shape and a sorting wheel is arranged on the conveyor belt. In order to cooperate with the sorting wheel, a swingable balance wheel is arranged on the frame. The axle of the sorting wheel is perpendicular to the conveying direction of the conveyor belt, that is, parallel to the width direction of the sorting machine. Under normal circumstances, when the axle of the balance wheel is perpendicular to the axle of the sorting wheel, the balance wheel does not contact the sorting wheel, and the sorting wheel remains stationary and does not rotate. When the balance wheel rotates a certain angle and contacts the sorting wheel, due to the relative motion between the balance wheel and the sorting wheel, the sorting wheel will rotate, thereby realizing the sorting function of the sorting wheel. This design meets the basic needs of logistics sorting to a certain extent.

[0003] However, the existing balance wheel adopts a fixed setting, which exposes obvious defects during actual operation. When the balance wheel is swinging, it often interferes with the sorting wheel. This interference will not only cause additional friction and collision between the sorting wheel and the balance wheel during operation, which may easily cause damage to the sorting wheel and the balance wheel, but also affect the normal operation stability of the equipment. Frequent fault repairs will also increase the operating costs of logistics companies, greatly affecting the service life of the sorting equipment, and is not conducive to the efficient and sustainable development of the logistics industry. Based on the above problems existing in the prior art, this case proposes a modular belt sorting machine, which aims to overcome the shortcomings of the balance wheel setting of the existing logistics sorting machine.

[0011] In a preferred embodiment, the conveyor belt includes a plurality of connecting units, and the connecting units include a plate body and a plurality of sorting wheels. The plate body is provided with a plurality of mounting openings, and the sorting wheels are installed in the mounting openings. The plurality of mounting openings are arranged in a straight line. A first connecting member is provided on one side of the plate body, and a second connecting member is provided on the other side. The first connecting member and the second connecting member of adjacent connecting units are connected in a straight line.

[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. In the first connecting members and the second connecting members that are cooperatively connected to each other, the second connecting plate is inserted into the gap between two adjacent first connecting plates, and the connecting shaft passes through the first connecting plates and the second connecting plates to form the ring-shaped conveyor belt.

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

[0016] Compared with the prior art, the modular belt sorting machine of the present invention, when working, the frame is used for supporting, the power component is used for driving the conveyor belt so that the conveyor belt moves in a circular motion, which can be set as a motor, the sorting grid is used to receive the sorted goods, the centering action component is used to realize the centering of the goods, and the conveyor belt is used to realize transportation and sorting.

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. A balance wheel driving component is provided on the intermediate floating plate 5. The balance wheel assembly includes a plurality of balance wheel units. The balance wheel unit is provided with a balance wheel driven component that cooperates with the balance wheel driving component. The balance wheel unit passes through the rising top plate 6 and rises and falls following the rise and fall of the rising top plate 6. A horizontal long hole 10 is provided on the vertical lifting plate 9. The lifting cam 7 is arranged in the horizontal long hole 10. A vertical long hole 12 is provided on the horizontal follower plate 11. The transverse cam 8 is arranged in the vertical long hole 12. The transverse cam 8 and the lifting cam 7 are respectively arranged with the vertical long hole 12 and the transverse long hole 10, so that during a lifting action, the swinging action of the balance wheel unit presents a fast-first-then-slow manner, and the rising action presents a slow-first-then-fast manner.

[0033] In a modular belt sorting machine of the present embodiment, when working, the frame 25 is used for supporting, the power component is used for driving the conveyor belt 24 so that the conveyor belt 24 moves in a circular motion, which can be set as a motor, the sorting grid 26 is used for receiving the sorted goods, the centering action component is used for centering the goods, and the conveyor belt 24 is used for conveying and sorting.

[0034] Its driving motor 1 is the power source for the entire sorting unit control, which is installed below the lower base plate 3 and connected to the driving shaft 2. The driving shaft 2 drives the lifting cam 7 and the transverse cam 8 to rotate synchronously. The vertical lifting plate 9 is connected to the lifting top plate 6, and the lifting top plate 6 is driven to move up and down by the movement of the lifting cam 7 in the transverse long hole 10; the horizontal follower plate 11 is connected to the intermediate floating plate 5, and the horizontal movement of the intermediate floating plate 5 is realized by the rotation of the transverse cam 8 in the vertical long hole 12.

[0035] During the sorting process, when sorting is not required, the balance wheel assembly is in a low position, and the conveyor belt 24 does not perform the sorting action. When sorting is required, the drive motor 1 is started, the drive shaft 2 rotates, and the lifting cam 7 and the transverse cam 8 rotate accordingly.

After the action is completed, the drive motor 1 reverses, and through the same control principle, the rising top plate 6 and the middle floating plate 5 are reset, the balance wheel assembly returns to the low position, and the conveyor belt 24 stops sorting.

[0036] This structural setting brings about significant technical effects. First, it effectively solves the interference problem between the balance wheel and the sorting wheel 14 in the prior art, reduces the wear and failure of the equipment, and extends the service life of the equipment. Secondly, through precise mechanical transmission and control, the efficient and accurate execution of the sorting action is achieved, and the efficiency of logistics sorting is improved. Most importantly, during the entire action execution process, the swinging action of the balance wheel is fast first and then slow, and the rising action is slow first and then fast. At the end of the rising action, the swinging action has been basically completed, so that before the balance wheel contacts the sorting wheel 14, the swinging action is basically completed, avoiding the problem of mutual interference between the balance wheel and the sorting wheel 14 in the prior art. In addition, the structural design of the component is reasonable, the various components work together, and the stability is strong, which reduces the operating costs of logistics companies and provides strong support for the efficient and sustainable development of the logistics industry.

[0037] Regarding the problem of how to achieve the action completion time between the transverse shift cam 18 and the lifting cam 17, it is achieved by setting the matching relationship between the transverse shift cam 8 and the vertical long hole 12, and the matching relationship between the lifting cam 7 and the transverse long hole 10. Those skilled in the art can make this shape setting.

[0038] The "one lifting action process" refers to the process in which the lifting top plate 6 rises once, that is, the process in which the balance wheel assembly rises once.

[0039] In order to adjust the swing amplitude, the transverse shift cam 8 includes a cam body 27 and a cam sleeve 28. The inner wall of the cam sleeve 28 is provided with a limit groove 29. The cam body 27 is provided with a limit strip. The cam sleeve 28 is sleeved on the cam body 27. The limit strip matches the limit groove 29. The cam sleeve 28 is made of rubber material. By replacing the cam sleeve 28, the eccentric position of the transverse shift cam 8 can be adjusted. By adjusting the eccentric position, the swing amplitude of the swing unit can be adjusted to different degrees.

[0040] The material of the cam sleeve 28 is not limited to rubber material. Any material can be used as long as it is easy to assemble and can realize the combination of the cam sleeve 28 and the cam body 27. However, a certain structural strength must be ensured at the same time.

[0041] Regarding how the cam sleeve 28 is set to achieve adjustment of the eccentric position: Since the cam sleeve 28 is sleeved 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.

[0042] In order to realize convenient installation of the cam sleeve 28 , a docking interface may be provided on the cam sleeve 28 , and connection may be realized by connecting a buckle, so that the cam sleeve 28 may be sleeved on the cam body 27 by opening the docking interface.

[0043] In this embodiment, the transverse long hole 10 and the vertical long hole 12 are both configured as long oval holes, the lifting cam 7 and the transverse cam 8 are both configured as circular shapes and eccentrically arranged on the drive shaft 2, and when the rising top plate 6 is in the lowest position, the points on the circumference of the lifting cam 7 and the transverse cam 8 that are farthest from the drive shaft are in the lowest position.

[0044] Regarding the cooperation between the transverse long hole 10 and the lifting cam 7, and the cooperation relationship between the vertical long hole 12 and the transverse cam 8, more specifically: the transverse long hole 10 and the vertical long hole 12 are both set as long round holes, that is, the ends are set as circular long holes, and the two ends are connected by a straight line segment. The lifting cam 7 and the transverse cam 8 are both set as circles and eccentrically set on the drive shaft 2. In the non-sorting state, that is, when the rising top plate 6 is at the 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 the lowest position, that is, the longest swing arm is in a vertical state.

The plate body 13 is provided with a plurality of mounting openings, and the sorting wheels 14 are installed in the mounting openings. The plurality of mounting openings are arranged in a straight line. A first connecting member is provided on one side of the plate body 13, and a second connecting member is provided on the other side. The first connecting member and the second connecting member of the adjacent connecting units are connected to form a ring-shaped conveyor belt 24. The plurality of connection units are connected to form a whole. When performing a sorting action, the pendulum wheel contacts the sorting wheel 14, thereby realizing the execution of the sorting action.

[0049] Specifically, the first connection includes a plurality of first connection plates 15 and a connection shaft (not shown in the figure), and the second connection member includes a plurality of second connection plates 16. In the first connection member and the second connection member that are connected to each other, the second connection plate 16 is inserted into the gap between two adjacent first connection plates 15, and the connection shaft passes through the first connection plate 15 and the second connection plate 16. Through such a structural setting, the rotation connection of the adjacent connection units is achieved.

[0050] Furthermore, the balance wheel driving component is configured as a rack 22, and the balance wheel driven component is configured as a gear 21, and the swing of the balance wheel unit is achieved through the cooperation of the gear 21 and the rack 22.

[0051] Specifically, the plurality of balance wheel units are arranged in multiple rows, the number of the racks 22 is the same as the number of rows in which the balance wheel units are arranged, each rack 22 controls the swing of one row of the balance wheel units, and the synchronous movement of the plurality of racks 22 is achieved through the movement of the intermediate floating plate 5, thereby achieving the synchronous movement of the plurality of balance wheel units.
