Description

Technical Field

[0001] This utility model relates to the field of logistics transportation equipment, specifically to a cross-belt sorting machine. Background Technology

[0002] A cross-belt sorting system is a logistics transportation device that connects a main drive belt conveyor and sorting trolleys carrying smaller belt conveyors. Because the conveying direction of the main drive belt conveyor intersects with the running direction of the sorting trolleys, the materials to be sorted are placed on the sorting belts of the sorting trolleys. During operation, the sorting machine drives multiple sorting trolleys to move. When a sorting trolley reaches its sorting position, the electric rollers on the trolley rotate, causing the sorting belt to rotate. The rotating sorting belt conveys the materials placed on it towards the sorting position until the materials are transported there, thus achieving the sorting purpose. A shock-absorbing mechanism is installed on the bottom track of the sorting trolleys to cushion the movement.

[0003] The existing shock absorption mechanism at the bottom of the sorting trolley has the following problems: the existing shock absorption structure is usually only distributed in pairs about the central axis of the main drive belt conveyor in the conveying direction, that is, about the length direction of the sorting trolley. However, when the sorting trolley turns, adjacent sorting trolleys are prone to collision. Moreover, due to the existence of gravity, the side of the sorting trolley closer to the corner of the running track in the width direction has a greater impact force on the sorting trolley that passed the corner when turning, which can easily damage the sorting trolley that passed the corner and affect the stability of the entire cross belt sorting machine. Utility Model Content

[0004] The technical solution adopted by this utility model to solve its technical problem is: to provide a cross-belt sorting machine, comprising:

[0005] The running track includes a horizontal section and a turning section. Multiple sorting trolleys are movably mounted on the running track. Adjacent sorting trolleys are connected to each other. The running track is equipped with a drive unit for driving the sorting trolleys, as well as a first shock-absorbing component and a second shock-absorbing component mounted on the sorting trolleys. The first shock-absorbing components are distributed in pairs about the central axis of the running track in the direction of travel.

[0006] The first shock absorption assembly includes a first pad block disposed on the running track and a first shock absorption pad elastically disposed on the first pad block. The first pad block has a moving groove for the first shock absorption pad to move. A telescopic spring is connected in the moving groove and is sleeved on the first shock absorption pad. The sorting trolley is provided with a pulley that is slidably disposed on the first pad block.

[0007] The second shock absorption component includes a second pad and a flexible pad connected to both ends of the sorting trolley in the width direction. The second pad is provided with a pressure groove that is adapted to the flexible pad. When the sorting trolley turns, the second pad contacts the pressure groove of the sorting trolley located at the front end of the running track in the running direction.

[0008] Furthermore, the pressure groove is an arc-shaped groove, and the flexible pad is spherical.

[0009] Furthermore, the second shock absorption assembly is provided in two sets on the sorting cart, and the second pads of the two sets of second shock absorption assemblies are located on different sides of the width direction of the sorting cart.

[0010] Furthermore, the first pad has a conical groove that communicates with the moving groove, and the pulley is slidably disposed in the conical groove.

[0011] Furthermore, the first shock-absorbing component also includes an elastic pad disposed between the tapered groove and the pulley.

[0012] Furthermore, the sorting trolley includes a main frame, a drive module, and a conveyor belt. The conveyor belt is mounted on the main frame, and the drive module is used to drive the conveyor belt to run.

[0013] Furthermore, the sorting trolley also includes a support frame mounted on the main frame, the support frame having a rotating shaft coaxially connected to a pulley, and the running track having a groove adapted to the pulley.

[0014] Furthermore, the support frame is provided with a limiting wheel, which is rotatably disposed in the sliding groove, and the plane where the limiting wheel is located is perpendicular to the plane where the pulley is located.

[0015] Furthermore, the sorting carts are connected by radial clearance bearings, and the radial clearance bearings of the sorting carts are connected to the rotating shafts of adjacent sorting carts.

[0016] Furthermore, the drive module includes a driving roller and a driven roller, both of which are electric rollers. The driving roller is used to drive the driven roller to rotate and drive the conveyor belt to run.

[0017] The beneficial effects of this utility model are: by setting the first shock-absorbing component and the second shock-absorbing component, the sorting trolley is shock-absorbing at both ends of the running track direction, thereby reducing the damage caused to the previous sorting trolley by collision when the adjacent sorting trolley turns, thus improving the stability of the entire cross belt sorting machine.

Detailed Implementation

[0025] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] Please refer to Figure 1This utility model embodiment provides a cross-belt sorting machine 100, including a running track 10. The running track 10 includes a horizontal section 11 and a turning section 12. A plurality of sorting trolleys 20 are movably arranged on the running track 10, and adjacent sorting trolleys 20 are interconnected. The running track 10 is provided with a drive component for driving the sorting trolleys 20, and a first shock-absorbing component 30 and a second shock-absorbing component 40 are arranged on the sorting trolleys 20. The first shock-absorbing components 30 are distributed in pairs about the central axis of the running direction of the running track 10. Further, in this embodiment, the drive component is a linear motor (not shown in the figure).

[0027] By setting the first shock-absorbing component 30 and the second shock-absorbing component 40, the sorting trolley 20 is damped at both ends of the running direction of the running track 10, thereby reducing the damage caused to the previous sorting trolley 20 due to collision when the adjacent sorting trolley 20 turns, thus improving the stability of the entire cross belt sorting machine 100.

[0028] Please refer to Figure 2 and Figure 3 The first shock-absorbing assembly 30 includes a first pad 31 disposed on the running track 10 and a first shock-absorbing pad 32 elastically disposed on the first pad 31. The first pad 31 has a moving groove 311 for the first shock-absorbing pad 32 to move. A telescopic spring 312 is connected inside the moving groove 311 and is sleeved on the first shock-absorbing pad 32. The sorting trolley 20 is provided with a pulley 21 slidably disposed on the first pad 31. Specifically, the width of the moving groove 311 is greater than the width of the first shock-absorbing pad 32. One end of the telescopic spring 312 is fixedly connected to the first shock-absorbing pad 32, and the other end of the telescopic spring 312 is fixedly connected to the groove wall of the moving groove 311.

[0029] Furthermore, the first pad 31 has a conical groove 313 that communicates with the moving groove 311, and the pulley 21 is slidably disposed within the conical groove 313. The conical groove 313 prevents the pulley 21 from easily shifting outward, thereby improving the stability of the pulley 21's movement.

[0030] For further details, please refer to Figure 3 The first shock-absorbing component 30 also includes an elastic pad 33 disposed between the conical groove 313 and the pulley 21. The elastic pad 33 further offsets the force on the sorting cart 20, improving the shock absorption performance of the sorting cart 20. Specifically, in this embodiment, the top end of the first shock-absorbing pad 32 is configured as a cone shape adapted to the conical groove 313, and the elastic pad 33 is a conical structure adapted to the top end of the first shock-absorbing pad 32.

[0031] Please refer to Figure 4The second shock absorption assembly 40 includes a second pad 41 and a flexible pad 42 connected to both ends of the sorting trolley 20 in the width direction. The second pad 41 is provided with a pressure groove 411 that is adapted to the flexible pad 42. When the sorting trolley 20 turns, the second pad 41 comes into contact with the pressure groove 411 of the sorting trolley 20 located at the front end of the running direction of the running track 10.

[0032] Furthermore, the pressure groove 411 is an arc-shaped groove, and the flexible pad 42 is spherical. More specifically, in this embodiment, the arc of the cross-section of the pressure groove 411 is a superior arc, so that when turning, the flexible pad 42 can contact the pressure groove 411 from multiple contact points, and the deformation of the flexible pad 42 can offset part of the impact force when the sorting cart 20 collides, thereby reducing the damage to the sorting cart 20 when turning.

[0033] Please refer to Figure 2 Furthermore, two sets of the second shock-absorbing components 40 are provided on the sorting cart 20, and the second pads 41 of the two sets of second shock-absorbing components 40 are located on different sides of the width direction of the sorting cart 20. When the running direction of the running track 10 is opposite to that shown in the figure, the forces on both sides of the width direction of the sorting cart 20 are uniform.

[0034] It is understandable that multiple sets of the second shock absorber 40 can be set, and the specific position of the second shock absorber 40 can be determined according to the specific collision position of the sorting trolley 20 under actual conditions.

[0035] Furthermore, the material of the second pad 41 is set to rubber.

[0036] For further details, please refer to Figure 2 and Figure 5 The sorting trolley 20 includes a main frame 22, a drive module, and a conveyor belt 24. The conveyor belt 24 is mounted on the main frame 22, and the drive module is used to drive the conveyor belt 24. Furthermore, the drive module includes a drive roller 231 and a driven roller 232, both of which are electric rollers. The drive roller 231 drives the driven roller 232 to rotate, thereby driving the conveyor belt 24.

[0037] Furthermore, the sorting trolley 20 also includes a support frame 25 mounted on the main frame 22. The support frame 25 is provided with a rotating shaft 251, which is coaxially connected to the pulley 21. The running track 10 is provided with a groove 13 that is compatible with the pulley 21.

[0038] Furthermore, the support frame 25 is equipped with a limiting wheel 252, which is rotatably disposed within the slide groove 13. The plane of the limiting wheel 252 is perpendicular to the plane of the pulley 21. The limiting wheel 252 limits the sorting trolley 20, making it difficult for the support frame 25 of the sorting trolley 20 to deviate from the circular track.

[0039] Furthermore, since the spacing between adjacent sorting carts 20 changes when the sorting cart 20 passes through the turning section 12 of the running track 10, a radial clearance bearing 26 is provided in this embodiment to connect adjacent sorting carts 20. The radial clearance bearing 26 of the sorting cart 20 is connected to the rotating shaft 251 of the adjacent sorting cart 20.
