Description

Technical Field

[0001] The utility model relates to the technical field of logistics, in particular to a full-automatic equidistant single-piece flow output logistics line based on vision and photoelectric control. Background Art

[0002] With the continuous development of the logistics and express delivery industry, the volume of express parcels is also increasing. Large mail processing centers in various places have adopted fully automatic sorting machines to sort parcels.

[0003] The current fully automatic parcel sorting process is as follows: before the parcel enters the sorting machine, it needs to be pre-processed by equipment. When the parcel is unloaded, it is piled up tightly together. The parcel passes through the conveyor line module, space separation module, plane separation module, rejection module, gap adjustment module and other equipment to become a single piece flow, and then enters the sorting machine to complete the sorting.

[0004] When a large number of packages enter the conveyor line, after the packages are separated in space and plane, a small number of packages will still be piled together and inseparable or the distance between the front and rear packages is very small. The packages that cannot be separated will be removed. After removal, the amount of packages on the logistics line will decrease, reducing the efficiency of the overall logistics line. When the packages with small spacing pass through the balance wheel, due to the different friction between the bottom of the front and rear packages and the balance wheel, there is a probability that they will collide with each other, which can cause the packages to be delivered in pairs, reducing the accuracy of the logistics line. Therefore, the utility model proposes a fully automatic equidistant single-piece flow output logistics line based on vision and photoelectric control. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model can be applied to the automatic line of the parcel sorting machine (such as Figure 2 ), one logistics line of the utility model can deliver parcels to two infeed stations. The efficiency of one infeed station is 3000PPH, and the logistics line of the utility model can reach an effective efficiency of 6250PPH, which can fully supply parcels to two infeed stations.

[0028] The logistics line of the utility model is located in the middle of the automatic line. After the parcel is unloaded from the truck, it enters the conveying equipment. After transmission, the parcel will enter the logistics line of the utility model. In the logistics line of the utility model, it is processed by different equipment. Through algorithm control, the piled and different types of parcels are output to two supply tables in single-piece flows with equal spacing, and finally put into the parcel sorting machine for sorting.

[0029] The main components of the fully automatic equidistant single-piece flow output logistics line based on vision and photoelectric control in this utility model are as follows: Figure 1 ):

[0030] 1. Spatial separation module: mainly composed of 2 chutes, 3 horizontal belt conveyors, 4 climbing belt conveyors and 1 set of spatial separation vision system.

[0031] 2. Plane separation module: It is mainly composed of a 4×10 small narrowband machine array, 1 whole-bit module, 1 dual-band unit, and 1 plane separation vision system.

[0032] 3. Rejection module: mainly composed of 1 horizontal belt conveyor, 1 balance wheel and 1 rejection vision system.

[0033] 4. Gap adjustment module: mainly composed of 6 high-speed belt conveyors.

[0034] Its main network framework diagram is as follows ( Figure 3 ):

[0035] The logistics line of the utility model has a PLC, which is responsible for linking various modules in the logistics line and exchanging information with the centralized control PLC. The core algorithm for controlling the distance between packages is also controlled by this PLC.

[0036] The utility model discloses a fully automatic equidistant single-piece flow output logistics line based on vision and photoelectric control, which mainly solves the problems of insufficient package flow and unstable control of package spacing on the logistics line.

[0037] Its main working process is as follows:

[0038] 1. After the parcels are unloaded, there will be a lot of stacking. When passing through the spatial separation, the spatial separation uses vision to judge the stacking situation of the parcels on the current belt, and then uses the acceleration and deceleration of the belt, the inertia of the parcel itself, the angle of the climbing belt, etc. to make the parcels stacked up and down as flat as possible.

[0039] 2. After the packages are separated from the space, they will enter the plane separation. The plane separation uses visual judgment to turn the flat packages into single-piece flow and transport them one by one. If the vision detects that there are overlapping packages, the plane separation will also try to separate the overlapping packages.

[0040] 3. After the package is separated from the plane, it will enter the rejection module, which uses vision to determine whether the current package is stacked together. If the package is stacked together, the balance wheel will adjust the rotation direction when the package passes through the balance wheel, swing the package to the return line, and then re-enter the space separation for separation again. If the package is not stacked, the package will enter the gap adjustment module.

[0041] 4. After the package enters the gap adjustment module, each section of the gap adjustment module belt has photoelectricity, which uses photoelectricity to calculate the distance between packages, and then the belt controls the distance between packages to about 400mm by changing speed. This module adjusts the distance between packages, caches packages, and improves the effective efficiency of the logistics line.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
