[0002] With the rapid development of e-commerce, the express logistics industry has developed rapidly. Logistics is to meet the needs of customers and realize the whole process of planning, implementation and management of goods from the place of production to the place of consumption at the lowest cost. In this process, goods are composed of transportation, service, distribution, warehousing, packaging, loading and unloading, sorting and other links. When sorting, the size and weight of the logistics will be considered to ensure that the logistics can be delivered to the destination in the most economical and efficient way.

[0003] At present, logistics sorting is generally carried out through transportation equipment.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] Example:

[0031] Reference Figure 1-Figure 6 A logistics sorting device for logistics includes a support frame 1, and also includes: a conveying device 2 and a first bracket 3 arranged on the support frame 1. The specific structure of the conveying device 2 can refer to the technical scheme in the prior art. Those skilled in the art can know it and will not be described in detail here. It needs to be explained that the conveying device 2 mainly includes structures such as conveying rollers, conveyor belts, and drive motors. Among them, the first bracket 3 is provided with a height sorting unit and a width sorting unit, which are respectively used to monitor the height and width of the logistics; a guide unit arranged on the support frame 1, and the height sorting unit and the width sorting unit are connected to the guide unit through a pipeline, which is used to guide the logistics to different directions according to the volume of the logistics; a weight sorting unit arranged on the support frame 1, which is used to sort the goods according to their weight; a partition component arranged on the side of the support frame 1 close to the width sorting unit, is used to separate the logistics on the conveying device 2.

[0032] Reference Figure 1-Figure 3 The height sorting unit includes a limit rod 4 slidably connected to the first bracket 3, and a pressing piece 5 is fixedly connected to the end of the limit rod 4 close to the conveying device 2, and an anti-slip plate 6 is fixedly connected to the end of the limit rod 4 away from the conveying device 2, and a first spring 7 is fixedly connected between the anti-slip plate 6 and the first bracket 3, and a driving cylinder 8 fixedly connected to the first bracket 3 is fixedly connected to the side of the pressing piece 5 away from the conveying device 2, wherein the limit rod 4 and the driving cylinder 8 both pass through the first bracket 3, and the first spring 7 is sleeved on the limit rod 4, and the pressing piece 5 is located above the pushing plate 10, and the side of the pressing piece 5 close to the pushing plate 10 is inclined, and the inclination direction is the same as the conveying direction of the conveying device 2.

[0033] When the logistics are transported on the conveying equipment 2, when they come into contact with the pressing piece 5, if the height of the logistics is large, it will drive the pressing piece 5 to move upward and compress the driving cylinder 8 at the same time. In this process, since the pressing piece 5 is inclined along the conveying direction of the logistics, it will not affect the transportation of the logistics. If the height of the logistics is small, the logistics will not come into contact with the pressing piece 5 during the transportation process (it should be explained that during the transportation of logistics, in order to ensure the stability of the logistics transportation, the maximum size of the logistics is usually not placed vertically, that is, during the transportation of the logistics, the size that comes into contact with the conveying equipment 2 is usually greater than the height).

[0034] Reference Figure 1 and Figure 3 The width sorting unit includes a rotating pin 9 symmetrically fixedly connected to the support frame 1, a push plate 10 is rotatably connected to the rotating pin 9, and an annular cylinder 11 is fixedly connected between the push plate 10 and the first bracket 3, wherein the bottom of the push plate 10 is in contact with the conveying equipment 2, the push plate 10 is located below the pressing member 5, the annular cylinder 11 is elastic and passes through the first bracket 3, and the axis of the annular cylinder 11 is located on the same straight line as the rotating pin 9.

[0035] When the logistics come into contact with the push plate 10 during the transportation process, the logistics may be offset during the transportation process. Under the action of the two groups of push plates 10, the goods can be gradually moved to the center position of the conveying equipment 2, so as to ensure the stability of logistics transportation and sorting. If the logistics is larger in volume, the push plate 10 can be driven to rotate and the annular cylinder 11 can be compressed at the same time. The volume of the logistics can be monitored by driving the compression amount of the cylinder 8 and the annular cylinder 11, so as to facilitate the subsequent sorting of the logistics.

[0036] Reference Figure 1 and Figure 4 The guide unit includes a second bracket 14 fixedly connected to the support frame 1, a second rotating cylinder 15 fixedly connected to the second bracket 14, a rotating shaft 16 connected to the side of the second rotating cylinder 15 close to the conveying device 2, a guide plate 17 fixedly connected to the rotating shaft 16, the second rotating cylinder 15 is located at the center of the second bracket 14, the rotating shaft 16 is connected to the output end of the second rotating cylinder 15, the guide plate 17 is in contact with the conveying device 2, and also includes an air intake pipe 18 and an air release valve 19 arranged on the second rotating cylinder 15, the air intake pipe 18 is connected to the driving cylinder 8 and the annular cylinder 11 through a pipeline, when the driving cylinder 8 and the annular cylinder 11 are compressed, the gas enters the second rotating cylinder 15 through the pipeline, and when the gas is more, the gas is discharged through the air release valve 19.

[0037] According to the compression amount of the driving cylinder 8 and the annular cylinder 11 (if the volume of the logistics is large), the compressed gas enters the second rotating cylinder 15 through the intake pipe 18 to drive the guide plate 17 to rotate. It should be explained that when the amount of gas entering the second rotating cylinder 15 is small, it will not drive the second rotating cylinder 15 to rotate. When the amount of gas entering the second rotating cylinder 15 reaches a certain amount, it will drive the second rotating cylinder 15 to rotate a specified angle (at this time, the guide plate 17 rotates to the symmetrical direction). When the logistics is separated from the push plate 10 and the pressing member 5, the gas flows back to the driving cylinder 8 and the annular cylinder 11, thereby driving the second rotating cylinder 15 to rotate to the initial position. This is a conventional means in the prior art, so it will not be elaborated. The excess gas is discharged through the air release valve 19 to ensure the stability of the guide plate 17. According to the different volumes of logistics, the logistics can be transported along different sides of the guide plate 17, thereby realizing the sorting of logistics according to volume.

[0038] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 The weight sorting unit includes a rotating frame 20 rotatably connected to a support frame 1, a sorting plate 21 is fixedly connected to one end of the rotating frame 20 away from the support frame 1, a partition 22 is fixedly connected to the sorting plate 21, a plurality of fixed cylinders 23 are fixedly connected to one side of the support frame 1 close to the sorting plate 21, a movable rod 24 is fixedly connected to one side of the sorting plate 21 close to the fixed cylinder 23, wherein one end of the sorting plate 21 is in contact with the conveying device 2, the partition 22 is located at the center of the sorting plate 21, and the movable rod 24 extends to the inside of the fixed cylinder 23 at one end away from the sorting plate 21, the fixed cylinder 23 and the movable rod 24 are both arranged in an arc shape, and the axis of the fixed cylinder 23 and the movable rod 24 are located on the same straight line with the axis of the rotating frame 20, and a reset mechanism is arranged between the fixed cylinder 23 and the movable rod 24.

[0039] After being sorted by the guide plate 17, the logistics will fall onto the sorting plate 21 as it is transported by the conveying equipment 2, and will fall to different sides of the partition 22 according to the different volumes. At this time, according to the weight of the logistics, the sorting plate 21 will be pressed down to different degrees, and finally it will fall onto different conveyor belts through the sorting plate 21 to continue subsequent work to ensure the subsequent sorting of the logistics (for example, by scanning the logistics order number, sorting the logistics according to the area, etc.).

[0040] Reference Figure 6The reset mechanism includes a slider 25 arranged in the fixed cylinder 23, a second spring 26 is fixedly connected between the slider 25 and the movable rod 24, a movable convex ring 27 is fixedly connected to the outer wall of the slider 25, and a fixed convex ring 28 matching the movable convex ring 27 is fixedly connected to the inner wall of the fixed cylinder 23, wherein both the movable convex ring 27 and the fixed convex ring 28 are elastic, when the pressure between the movable convex ring 27 and the fixed convex ring 28 reaches a threshold value, the movable convex ring 27 moves to the other side of the fixed convex ring 28, and also includes a sealing ring 29 fixedly connected to the inner wall of the fixed cylinder 23, the sealing ring 29 is located on the side of the fixed convex ring 28 away from the movable rod 24, and a reset cavity is formed between the slider 25, the movable convex ring 27 and the fixed convex ring 28 and the fixed cylinder 23.

[0041] When logistics of different weights fall onto the sorting plate 21, the second spring 26 will have different lengths, and this can also prevent lighter logistics from stably falling from the sorting plate 21 to the conveyor belt. When the weight of the logistics reaches a certain value, that is, when the pressure between the movable convex ring 27 and the fixed convex ring 28 reaches the threshold, the movable convex ring 27 will move to the other side of the fixed convex ring 28, so that the sorting plate 21 rotates to the lowest angle. Since the compression of the gas is relatively large, when the logistics is in a relatively heavy weight, even if the weight of the logistics is large, the height difference between the lowest point of the sorting plate 21 and the conveyor belt will be relatively small, which can prevent heavier logistics from being damaged during sorting. When the logistics is separated from the sorting plate 21, the compressed gas will drive the slider 25 to move to the initial position until it drives the movable convex ring 27 to move to the initial side of the fixed convex ring 28.

[0042] Reference Figure 1-Figure 2 The partition assembly includes a first rotating cylinder 12 symmetrically fixedly connected to the outer wall of the support frame 1, a baffle 13 is arranged between the two groups of first rotating cylinders 12, the baffle 13 is in contact with the conveying device 2, and the baffle 13 is located on the side of the conveying device 2 close to the push plate 10. The air inlet end of the first rotating cylinder 12 is connected to the driving cylinder 8 and the annular cylinder 11 through a pipeline.

[0043] When sorting logistics with a smaller volume, the guide plate 17 will not rotate due to the small pressure between it and the push plate 10, so it does not need to stay for a long time. When sorting logistics with a larger volume, in order to avoid multiple logistics passing through the pressing piece 5 and the push plate 10 at the same time, affecting the judgment of the logistics volume, therefore, when the driving cylinder 8 and the annular cylinder 11 are compressed, part of the gas will be transported to the first rotating cylinder 12 through the pipeline, driving the baffle 13 to rotate to one side of the logistics transportation direction, and because the volume of the logistics is large, the tail of the logistics is still on the baffle 13 at this time. When the logistics is separated from the baffle 13, the baffle 13 will quickly rotate and stand up to block the subsequent logistics until the previous logistics is separated from the push plate 10. The baffle 13 will rotate to the initial position under the push of the subsequent logistics, and continue to sort the subsequent logistics.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
