Description

Technical Field

[0001] This utility model belongs to the field of intelligent logistics sorting technology, specifically relating to an anti-fall device for intelligent logistics sorting. Background Technology

[0002] Smart logistics is a modern logistics model based on technologies such as the Internet of Things, big data, and artificial intelligence. It optimizes the entire logistics process (including warehousing, transportation, and distribution) through digitalization, automation, and intelligentization to achieve efficient, energy-saving, and environmentally friendly cargo flow. The automated sorting system of smart logistics is a key node connecting warehousing and distribution, directly affecting order processing efficiency and customer experience. Especially in e-commerce and cross-border logistics scenarios with high order volumes, sorting efficiency determines the throughput capacity of the overall logistics system. Automated sorting has become an essential support for the high complexity of modern logistics.

[0003] In sorting systems, a combination of horizontal and inclined conveyor belts is commonly used. When packages ascend an incline, insufficient friction may cause them to slip and slide down the inclined conveyor belt, affecting normal sorting. To prevent this, current sorting systems incorporate anti-slip and anti-fall devices. These include adding anti-slip patterns or special materials to the conveyor belt surface to increase friction, and installing flexible rubber skirts or transverse partitions on both sides of the belt to physically prevent packages from sliding backward. However, these methods are usually fixed and cannot be adjusted according to the condition of the packages during the sorting process. Flexible adjustments are possible. Taking the anti-slip texture on the conveyor belt surface as an example, in actual application scenarios, the bottom of the package contacts the highest point of the anti-slip texture. The conveyor belt speed is adjusted for different packages. For light and small items, the speed can be increased to improve efficiency, while for heavy or fragile items, the speed is reduced to reduce the risk of collision. When the conveyor belt speed is increased, the friction between the bottom of the package and the conveyor belt surface on the uphill section may not be enough to offset the component of gravity, causing the package to slide backward on the slope supported by the highest point of each anti-slip texture due to inertia. Under high speed, the contact time between the package and the conveyor belt is shortened, which may reduce the effective coefficient of friction, thereby increasing the risk of the package slipping.

[0004] Therefore, this utility model proposes an intelligent logistics sorting anti-fall device that can prevent express packages from sliding down the inclined section of the conveyor belt. Utility Model Content

[0005] In response to the problem in existing technologies that express packages may slide down slopes, thus affecting normal sorting, this utility model provides an intelligent logistics sorting anti-fall device.

[0006] This utility model adopts the following technical solution: a fall prevention device for intelligent logistics sorting, comprising a conveyor belt assembly and a set of fall prevention components, wherein the conveyor belt assembly includes a horizontally arranged first conveyor belt and an inclinedly arranged second conveyor belt.

[0007] The anti-fall component includes a set of torsion springs and baffles inclined on the second conveyor belt. The baffles are designed to be bidirectionally adjustable according to different application scenarios. The inclination angle of the baffles is greater than that of the second conveyor belt. The inclination angle of the baffles changes as the speed of the second conveyor belt increases. When the second conveyor belt transports express packages, the baffles pressed down by the express packages rotate, thereby reducing their inclination angle. The baffles not pressed down by the express packages form a blockage under the express packages, preventing the express packages from sliding down too much and affecting sorting efficiency.

[0008] Preferably, the anti-fall component further includes a mounting base fixedly installed on the surface of the second conveyor belt. The mounting base has a mounting groove, and a fixed shaft is fixedly installed in the mounting groove. The fixed shaft rotatably passes through a connecting rod, and the connecting rod is located in the mounting groove and rotatably connected to the mounting groove. The connecting rod is fixedly connected to a baffle, and a torsion spring is located at both ends of the baffle. One end of the torsion spring is fixedly connected to the side wall of the baffle, and the other end is fixedly connected to the mounting base.

[0009] Preferably, the side of the baffle away from the second conveyor belt is provided with an inclined surface, and the inclined surface is provided with a rubber layer.

[0010] Preferably, the conveyor belt assembly is mounted on a frame.

[0011] Preferably, the horizontal height of the lower end of the second conveyor belt is less than the horizontal height of the first conveyor belt.

[0012] Preferably, an auxiliary plate is provided at one end of the first conveyor belt near the second conveyor belt, and the auxiliary plate is fixedly connected to the frame.

[0013] Beneficial effects:

[0014] (1) The intelligent logistics sorting anti-fall device described in this utility model uses a rotatable baffle set on the second conveyor belt. When the baffle is pressed down by the express item, its tilt angle becomes smaller than that of the baffle that is not pressed down by the express item. This makes the baffle that is not pressed down by the express item block the express item. At the same time, the tilt angle of the baffle that is not pressed down changes according to the speed of the conveyor belt. When the speed is faster, the tilt angle of the baffle increases, the blocking surface of the express item increases, and the stability of the fast-running sorting of the conveyor belt is maintained.

[0015] (2) The intelligent logistics sorting anti-fall device described in this utility model only contacts the highest point of the baffle when the parcel comes into contact with the baffle. When the baffle is pressed and rotates, the contact surface between the inclined surface of the baffle and the parcel increases, increasing the friction coefficient between the parcel and the baffle. When combined with the baffle that is not pressed by the parcel, the parcel runs more stably on the slope section. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Example: Figures 1-5 The intelligent logistics sorting anti-fall device shown includes a conveyor belt assembly 2 and a set of anti-fall components 4. The conveyor belt assembly 2 includes a horizontally arranged first conveyor belt 21 and an inclined second conveyor belt 22. The anti-fall components 4 include a set of torsion springs 46 and a baffle 45 inclined on the second conveyor belt 22. The baffle 45 is configured to be bidirectionally adjustable according to different application scenarios. The inclination angle of the baffle 45 is greater than the inclination angle of the second conveyor belt 22. The inclination angle of the baffle 45 changes with the increase of the speed of the second conveyor belt 22. When the second conveyor belt 22 transports express items, the baffle 45 pressed down by the express items rotates, thereby reducing its inclination angle. The baffles 45 not pressed down by the express items form a blockage under the express items, preventing the express items from sliding down too much and affecting sorting efficiency.

[0024] In this embodiment, the parcel is conveyed from the first conveyor belt 21 to the second conveyor belt 22. When the parcel presses on part of the baffle 45 on the second conveyor belt 22, the baffle 45 rotates due to the weight of the parcel, and its tilt angle decreases. The baffle 45 pressed by the parcel provides support for the parcel. The rubber layer on the inclined surface 451 of the baffle 45 increases the friction, which drives the parcel to move towards the upper end of the second conveyor belt 22. The tilt angle of the baffle 45 not pressed by the parcel is greater than that of the pressed baffle 45, forming a barrier below the parcel and preventing the parcel from sliding down the slope significantly, which would affect the sorting efficiency.

[0025] like Figures 2-5As shown, the fall arrestor 4 also includes a mounting base 41 fixedly installed on the surface of the second conveyor belt 22. The mounting base 41 has a mounting groove 42, and a fixed shaft 43 is fixedly installed in the mounting groove 42. The fixed shaft 43 rotatably passes through a connecting rod 44. The connecting rod 44 is located in the mounting groove 42 and rotatably connected to the mounting groove 42. The connecting rod 44 is fixedly connected to a baffle 45. A torsion spring 46 is located at both ends of the baffle 45. One end of the torsion spring 46 is fixedly connected to the side wall of the baffle 45, and the other end is fixedly connected to the mounting base 41. A slope 451 is provided on the side of the baffle 45 away from the second conveyor belt 22, and a rubber layer is provided on the slope 451. The conveyor belt assembly 2 is installed on the frame 1. The horizontal height of the lower end of the second conveyor belt 22 is less than the horizontal height of the first conveyor belt 21. An auxiliary plate 3 is provided at the end of the first conveyor belt 21 near the second conveyor belt 22, and the auxiliary plate 3 is fixedly connected to the frame 1.

[0026] In this embodiment, the rotation range of the baffle 45 is limited, restricted by the opening of the mounting groove 42. When the baffle 45 rotates and comes into contact with the edge of the groove, it cannot continue to rotate. When the baffle 45 has its maximum inclination angle, the angle between the baffle 45 and the second conveyor belt 22 does not exceed 90 degrees. The stiffness of the torsion spring 46 is relatively small, allowing the inclination angle of the baffle 45 to change slightly with the running speed of the second conveyor belt 22. The express item presses down on the baffle 45, causing it to rotate under pressure. The baffle 45 moves closer to the second conveyor belt 22, and its inclination angle decreases. Multiple pressed baffles 45 provide support for the express item. The inclined surface 451 of the baffle 45 is provided with The rubber pad increases friction, and the angle of the baffle 45 that is not pressed down by the package is greater than that of the pressed baffle 45. It acts as a barrier under the package. If the package slides down during the conveying process, the baffle 45 below can prevent the package from sliding down further. When the speed of the second conveyor belt 22 is adjusted according to the sorting requirements, the angle of the baffle 45 can change according to the speed of the second conveyor belt 22. When the speed is faster, the baffle 45 is offset outward by centrifugal force. The centrifugal force overcomes the preload of the torsion spring 46, causing the angle of the baffle 45 to passively increase, increasing the blocking surface for the package, which can effectively block bagged light packages with irregular shapes.

[0027] In this embodiment, as Figure 1 and Figure 2 As shown, the express package is transported from the first conveyor belt 21 to the second conveyor belt 22. An auxiliary plate 3 is provided at the connection point. The express package is buffered by the auxiliary plate 3 under the transmission of the first conveyor belt 21 and then transferred to the second conveyor belt 22, which reduces the drop at the connection point of the first conveyor belt 21 and the second conveyor belt 22 and is beneficial to the transportation of the express package.

[0028] Working principle: When the conveyor belt assembly 2 is running, the parcels on the first conveyor belt 21, with the cooperation of the auxiliary plate 3, come onto the second conveyor belt 22. The baffle 45 that is pressed down by the parcel rotates, and the inclination angle of this part of the baffle 45 decreases. At the same time, the contact surface between the inclined surface 451 of this part of the baffle 45 and the bottom of the parcel increases, which increases the friction coefficient between the two and enhances the stability of the parcel on the slope. The inclination angle of the baffle 45 that is not pressed down by the parcel is greater than that of the baffle 45 that is pressed down by the parcel, forming a barrier under the parcel. If the parcel slides down, it can intercept the sliding parcel and prevent it from continuing to slide down, ensuring the normal operation of the second conveyor belt 22 on the slope. For different parcels, the running speed of the conveyor belt assembly 2 can have a certain impact on the inclination angle of the baffle 45. When the running speed of the second conveyor belt 22 is faster, the inclination angle of the baffle 45 that is not pressed down by the parcel increases, increasing the blocking surface for the parcel.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
