Online mixed stacking method based on buffer area

Abstract

The invention relates to an online mixed stacking method based on a buffer area. The method comprises the following steps that A, goods on a conveyor belt are sequentially placed in the buffer area, the size information of the goods is collected, and the placing posture of the goods is generated; B, according to the space condition occupied by the placement postures of the cargoes, waste spaces generated by different placement postures of a single cargo and different placement sequences of a plurality of cargoes under different stacking modes when the cargoes are stacked to the tray are calculated, and the waste spaces are gaps between the cargoes and gaps between the cargoes and the tray; C, a stacking method with the least waste space is selected, the cargoes are selected one by one from the buffer area according to the stacking method, and the cargoes are placed into the trays; and D, if the tray space reaches the upper limit, the tray is replaced; and if not, the steps A, B and C are repeated. The stacking time is shortened, and the utilization rate of the stacking space is increased.

Description

technical field [0001] The invention relates to the technical field of cargo palletizing, in particular to an online mixed palletizing method based on a buffer zone. Background technique [0002] With the improvement of the overall mechanization, automation and digitalization level of my country's industry, the types and quantities of goods in the factories of Chinese enterprises have also begun to increase, which has also led to the rapid development of the logistics industry. At the same time, due to the different sizes of goods and frequent transportation, the palletizing industry will inevitably face upgrading and transformation. Therefore, the pros and cons of palletizing algorithms have an important impact on the transportation costs of the entire industry, especially in the transportation of mixed goods, the improvement of the space utilization of palletizing can often bring significant economic benefits. Therefore, the significance of palletizing algorithm optimizat...

Problems solved by technology

[0003] At present, the palletizing schemes targeted by the palletizing algorithm mainly focus on two schemes: offline design with known cargo information and online design with the same cargo size. Among them, offline design with known cargo information is mainly The disadvantage is that it is necessary to know the order of goods on the assembly line in advance and then design the palletizing scheme offline, which will easily increase the time of palletizing, increase the production cycle, and reduce production efficiency

At the same time, another kind of online design and palletizing scheme with the same size of goods is limited for the situation. It can only be designed and palletized for a certain kind of goods online, which is not very inclusive. It is different from the actual production situation of most existing enterprises. The mixed goods palletizing that you want to implement does not match

Furthermore, under the premise of no cargo information, online stacking of the goods on the conveyor belt can easily achieve a low space utilization rate, which is inconsistent with the expected effect

In actual cargo transportation, the type of cargo is not unique, and the order and size of the cargo coming from the assembly line cannot be fully known in advance. These two main constraints make the existing palletizing scheme need to be improved
