Abstract

The invention discloses a cargo box closing method for an automatic storing and taking system of a compact robot. The cargo box closing method for the automatic storing and taking system of the compact robot comprises the following steps of 1) establishing a box closing model based on a cargo association rule by taking the shortest total walking distance in a cargo picking process of the robot asa target function according to the operation flow of the automatic storing and taking system of the compact robot and the reason causing long order processing time under the current common storage strategy; 2) considering the requirement that a mathematical model established in the step 1) should be preferentially placed at the position closest to the top layer of a grid cargo shelf and closest toa workstation for cargoes with high demand frequency, designing a distribution rule of workbins; and 3) using an intelligent algorithm to optimize and solve the cargo storage mode, and determining the optimal storage position of the cargoes. According to the cargo box closing method for the automatic storing and taking system of the compact robot provided by the invention, the order processing time of the system under the common cargo storage strategy can be reduced.

Description

technical field

[0001] The invention relates to the technical field of storage of compacted warehouse goods, in particular to a method for packing goods in a compact robot automatic access system. Background technique

[0002] With the rapid development of the mobile Internet, the diversity and explosive growth of customer needs, and the ever-shortening effective life cycle of products, it is gradually difficult for traditional automated access systems to adapt to the market. A new type of compact robot suitable for new retail and e-commerce companies Access systems are on the rise. The system has the characteristics of saving warehouse area, high design flexibility, flexible expansion, and high order processing accuracy.

[0003] Different from the traditional automated three-dimensional warehouse, the system does not need to leave aisle space, but a high-density storage area formed by stacking rows of boxes with the same shape and specification. The robot moves along the...

Examples

Embodiment Construction

[0043] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0044] The compacting robot automatic access system cargo packing method provided by the present invention is specifically implemented according to the following steps:

[0045] Step 1 takes the shortest total walking distance as the objective function in the picking process of the robot, and establishes a binning model based on goods association rules;

[0046] 1.1 Analyze the system operation process and the reasons for the long order processing time of the common storage strategy;

[0047] see figure 1 , the present invention designs the operation process of the following system, which is mainly divided into three steps: the system receives the customer order, and assigns it an idle robot. After receiving the order instruction, the robot walks from the waiting position to the target material box. If the box is not located on the top shelf of the shelf, the...
