Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of logistics sorting, in particular to a sorting friction structure and a sorting machine. BACKGROUND

[0002] In the logistics industry, efficient and accurate sorting work is crucial to improve logistics efficiency. The current widely used logistics sorting machine, one of the common structures is that the conveying belt is arranged in a ring shape, and the conveying belt is provided with a sorting wheel. In order to cooperate with the work of the sorting wheel, a swing wheel is arranged on the rack. The wheel shaft of the sorting wheel is perpendicular to the conveying direction of the conveying belt, that is, parallel to the width direction of the sorting machine. Under normal circumstances, when the wheel shaft of the swing wheel is perpendicular to the wheel shaft of the sorting wheel, the swing wheel does not contact the sorting wheel, and the sorting wheel remains in a stationary state and does not rotate. When the swing wheel rotates by a certain angle and contacts the sorting wheel, the sorting wheel will rotate due to the relative motion between the swing wheel and the sorting wheel, thereby realizing the sorting function of the sorting wheel. This design meets the basic needs of logistics sorting to some extent.

[0003] However, the existing swing wheel is fixedly arranged, which has obvious defects in actual operation. When the swing wheel is operated, interference often occurs between the swing wheel and the sorting wheel. This interference not only causes additional friction and collision between the sorting wheel and the swing wheel during operation, which easily damages the sorting wheel and the swing wheel, but also affects the normal operation stability of the equipment. Frequent breakdowns also increase the operating cost of logistics enterprises, greatly affect the service life of the sorting equipment, and are not conducive to the efficient and sustainable development of the logistics industry. Based on the above problems existing in the prior art, the present application proposes a sorting friction structure and a sorting machine to overcome the shortcomings of the existing swing wheel arrangement of the logistics sorting machine.

[0009] In a preferred embodiment, the balance wheel support comprises a balance wheel shaft, a balance wheel support and a balance wheel body. The balance wheel shaft is connected with the balance wheel support. The balance wheel body is arranged on the balance wheel support.

[0010] In a preferred embodiment, the chain plate comprises a plurality of connection units. The connection unit comprises a plate body and a plurality of sorting wheels. The plate body is provided with a plurality of mounting holes. The sorting wheels are mounted in the mounting holes. The mounting holes are arranged in a linear type. One side of the plate body is provided with a first connecting member. The other side of the plate body is provided with a second connecting member. The first connecting member and the second connecting member of adjacent connection units are connected.

[0011] In a preferred embodiment, the first connecting member comprises a plurality of first connecting plates and a connecting shaft, and the second connecting member comprises a plurality of second connecting plates, among the first connecting member and the second connecting member connected with each other, the second connecting plates are inserted into the gaps between two adjacent first connecting plates, and the connecting shaft passes through the first connecting plates and the second connecting plates.

[0012] In a preferred embodiment, the balance wheel driving member is provided as a rack, and the balance wheel driven member is provided as a gear.

[0013] In a preferred embodiment, a plurality of the balance wheel units are arranged in multiple rows, the number of the racks is the same as the number of the arranged rows of the balance wheel units, and each of the racks controls the swing of a row of the balance wheel units.

[0014] In a preferred embodiment, the driving motor and the driving shaft are connected through a synchronous belt.

[0015] A sorting machine comprises the sorting friction structure.

[0016] Compared with the prior art, the sorting friction structure of the application has the driving motor as the power source of the whole assembly, which is installed below the lower bottom plate and connected with the driving shaft. The driving shaft drives the lifting cam and the horizontal moving cam to rotate synchronously.

DETAILED DESCRIPTION

[0028] The application will be further described below in conjunction with the drawings.

[0029] The specific embodiments are only an explanation of the application, and are not a limitation of the application, and those skilled in the art can make modifications to the embodiments without creative contribution after reading the specification, and as long as the modifications are within the scope of the claims of the application, they are protected by the patent law. EMBODIMENT

[0030] As Figures 1 to 8As shown, a sorting friction structure includes a drive motor 1, a drive shaft 2, a lower bottom plate 3, a middle floating plate 5, a rising top plate 6, a jacking cam 7, a horizontal moving cam 8, a vertical jacking plate 9, a horizontal following plate 11, a balance wheel assembly and a chain plate, the drive motor 1 and the drive shaft 2 are installed below the lower bottom plate 3, the drive shaft 2 is connected with the drive motor 1, the middle floating plate 5 and the rising top plate 6 are arranged above the lower bottom plate 3, a plurality of first magnets 32 are arranged on the rising top plate 6, the rising top plate 6 is arranged above the middle floating plate 5, the jacking cam 7 and the horizontal moving cam 8 are arranged on the drive shaft 2 and rotate synchronously with the drive shaft 2, the vertical jacking plate 9 is connected with the rising top plate 6 and drives the rising top plate 6 to move up and down, the horizontal following plate 11 is connected with the middle floating plate 5 and drives the middle floating plate 5 to move horizontally, the middle floating plate 5 is provided with a balance wheel driving member, the balance wheel assembly includes a plurality of balance wheel units, each balance wheel unit is provided with a balance wheel driven member matched with the balance wheel driving member, the balance wheel unit passes through the rising top plate 6 and rises and falls with the rising and falling of the rising top plate 6, the top of the balance wheel unit is movably arranged, the top of the balance wheel unit is provided with a second magnet 33, a plurality of the first magnets 32 and a plurality of the balance wheel units are arranged one by one in correspondence, the first magnet 32 is arranged on the terminal side of the corresponding balance wheel unit in the direction of the goods conveying, the first magnet 32 and the second magnet 33 repel each other, the vertical jacking plate 9 is provided with a horizontal long hole 10, the jacking cam 7 is arranged in the horizontal long hole 10, the horizontal following plate 11 is provided with a vertical long hole 12, the horizontal moving cam 8 is arranged in the vertical long hole 12, and the chain plate is arranged in cooperation with the balance wheel assembly.

[0031] The sorting friction structure of the embodiment, the drive motor 1 is the power source of the whole assembly, which is installed below the lower bottom plate 3 and connected with the drive shaft 2. The drive shaft 2 drives the jacking cam 7 and the horizontal moving cam 8 to rotate synchronously. The vertical jacking plate 9 is connected with the rising top plate 6 and drives the rising top plate 6 to move up and down through the movement of the jacking cam 7 in the horizontal long hole 10. The horizontal following plate 11 is connected with the middle floating plate 5 and realizes the horizontal movement of the middle floating plate 5 through the rotation of the horizontal moving cam 8 in the vertical long hole 12. The balance wheel assembly includes a plurality of balance wheel units, which are matched with the middle floating plate 5 through the balance wheel driving member and the balance wheel driven member, can rise and fall with the rising and falling of the rising top plate 6, and realize the swing under the action of the middle floating plate 5.

[0032] During the execution of the sorting action, when sorting is not required, the balance wheel assembly is in the low position, and the chain plate does not perform the sorting action. When sorting is required, the driving motor 1 is started, the driving shaft 2 rotates, and the lifting cam 7 and the horizontal moving cam 8 rotate accordingly. The lifting cam 7 drives the vertical lifting plate 9, causing the lifting top plate 6 to rise and drive the balance wheel assembly to rise; at the same time, the horizontal moving cam 8 drives the horizontal follower plate 11, causing the intermediate floating plate 5 to move horizontally and in turn driving the balance wheel unit to swing. When the balance wheel unit rises to a certain position and contacts the chain plate, the chain plate begins to perform the sorting action. After the action is completed, the driving motor 1 is reversed, and through the same control principle, the lifting top plate 6 and the intermediate floating plate 5 are reset, the balance wheel assembly returns to the low position, and the chain plate stops sorting.

[0033] This structure setting brings 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 prolongs the service life of the equipment. Second, through precise mechanical transmission and control, efficient and accurate execution of the sorting action is achieved, improving the efficiency of logistics sorting. During the execution of the sorting action, due to the repulsion of the first magnet 32 and the second magnet 33, the height of the balance wheel unit on the terminal side of the direction of the goods transport is higher, and during the execution of the sorting, the conveying belt 24 first contacts the low position of the balance wheel unit, and then contacts the high position of the balance wheel unit, which can smoothly start the sorting of the conveying belt 24. In addition, the structure of the component is reasonable, the parts work cooperatively, the stability is strong, the operating cost of the logistics enterprise is reduced, and strong support is provided for the efficient and sustainable development of the logistics industry.

[0034] Regarding the effect of the higher side and the lower side of the balance wheel unit, specifically, during the execution of the sorting action, the conveying belt 24 first contacts the low position of the balance wheel unit, at which time the force between the conveying belt 24 and the balance wheel unit is small, and then contacts the high position of the balance wheel unit, at which time the force between the conveying belt 24 and the balance wheel unit is large, so the force exerted on the sorting wheel 14 on the conveying belt 24 has a process from small to large, and the change of force and the setting of slope are conducive to starting the sorting wheel 14. When the balance wheel unit is placed flat, a larger tension between the conveying belt 24 and the balance wheel unit is required, which will burden the power system, and the arrangement of the present case effectively alleviates this problem. In addition, due to the setting of the slope, the sorting wheel 14 completes a climbing process every time it passes through a sorting unit, which will produce a slight vibration, which is transmitted to the goods, which is conducive to smoothly moving the goods and facilitating the sorting work.

[0035] Further, the first magnet 32 and the second magnet 33 are arranged to provide a force support for the lifting of the one side of the balance wheel unit, and the force support is elastic rather than rigid, so that the balance wheel unit will not be stuck due to excessive interaction force between the balance wheel unit and the conveying belt 24 during the movement of the conveying belt 24. Compared with directly arranging a spring to provide elasticity, the arrangement of the spring will significantly increase the complexity of the structure due to the swing action of the balance wheel unit, which will not only reduce the reliability of the structure, but also increase the manufacturing cost.

[0036] After the one side of the balance wheel unit is lifted, the top of the balance wheel unit forms a slope, and the conveying belt 24 is equivalent to a climbing process when passing through the slope. During the passing through of the plurality of balance wheel units, the climbing process is repeatedly performed, and the conveying belt 24 generates a slight vibration in the process, which can avoid the goods from being stuck during the sorting, and solve the problem of the start of the sorting wheel 14. In general, if the top of the balance wheel unit is in a horizontal state, it is difficult to ensure that the sorting wheel 14 and the top of the balance wheel unit are in contact every time to drive, unless a large tensioning force is arranged between the balance wheel unit and the sorting wheel 14, and the tensioning force will bring a running burden to the whole system. Through the height arrangement of the balance wheel unit in the present case, on the one hand, the climbing state can ensure that the top of the balance wheel unit and the sorting wheel 14 are in contact, and when reaching the top of the slope, the interaction force between the balance wheel unit and the sorting wheel 14 is large, but it is only a short and instantaneous, and the sorting wheel 14 will immediately reach the next bottom of the slope. At the top of the slope, through the large interaction force, the start of the sorting wheel 14 can be smoothly realized.

[0037] The terminal of the conveying direction of the goods refers to the terminal direction of the conveying direction of the goods.

[0038] In the present embodiment, the horizontal long hole 10 and the vertical long hole 12 are arranged as long circular holes, i.e. the long holes with circular ends, and the two ends are connected by a straight line segment. The lifting cam 7 and the horizontal moving cam 8 are arranged as circles and are eccentrically arranged on the driving shaft 2. In the non-sorting state, i.e. when the lifting plate 6 is in the lowest position, the points on the wheel circumference of the lifting cam 7 and the horizontal moving cam 8 farthest from the driving shaft are in the lowest position, i.e. the longest swing arm is in the vertical state. Through the cooperation of the horizontal moving cam 7 and the lifting cam 8 with the vertical long hole 12 and the horizontal long hole 10, the swing action of the balance wheel presents a mode of first fast and then slow during the whole action, and the lifting action presents a mode of first slow and then fast. In the final stage of the lifting action, the swing action has been basically completed, so that the swing action is basically completed before the balance wheel contacts the sorting wheel.
