Embodiment 1

like figure 1 Shown is a flow chart of a palletizing method proposed in this embodiment. The palletizing method is used to provide a palletizing plan, and obtain a preferred plan with the largest number of palletizing according to screening conditions. More specifically, the purpose of the present invention is to stack a plurality of cuboid-shaped goods (boxes) with the same size to be palletized on a rectangular pallet to obtain the optimal solution with the largest number of pallets; the traditional solution mainly relies on manual calculation. Carrying out the palletizing design of the boxes, the present invention provides a palletizing method based on a nonlinear programming-based palletizing design algorithm.

[0027] like figure 1 As shown, a palletizing method proposed in this embodiment includes:

(1) Obtain the length and width information of the pallet, and obtain the length and width information of the box;

(2) Execute the algorithm to obtain all palletizing plan...

Embodiment 2

The palletizing scheme output by the above method of the present invention cannot be displayed visually. Therefore, the present invention further provides a visualization method for the palletizing scheme, such as Figure 10 Shown is a flowchart of the algorithm in the visualization method, including:

(1) First, obtain the length and width information of the pallet, obtain the length and width information of the box, and obtain the palletizing plan ;Specifically, enter the palletizing plan ; Input the long side l and wide side b of the box. The length and width of the tray are generally preset and are fixed values. In this embodiment, it is assumed that the tray length L is 1200, and the tray width B is 1000.

[0041] (2) Next, calculate the minimum lengths required for the boxes to be placed on the pallet in the horizontal (x) and vertical (y) directions in the palletizing plan;

Among them, the minimum required length in the horizontal direction is set to Lg, and Lg is det...

Embodiment 3

The gap between boxes is not set in the visualized palletizing plan output by the above method of the present invention. Therefore, the present invention further optimizes the visualization method of the above-mentioned palletizing plan, such as Figure 11 Shown is a flowchart of the algorithm in the improved visualization method, including:

(1) First, use x_interval1, x_interval2, x_interval3, x_interval4 to represent the gap values ​​of the first to fourth sub-regions (counterclockwise) in the horizontal direction; use G1, G2, G3, G4 to respectively indicate whether the four sub-regions are placed in boxes or not In the case of , the value is 0 if there is, and 1 if there is no; the symbol Q() indicates that if the value in the parentheses is less than or equal to 0, it will take 1, and if it is greater than 0, the original value will be maintained.

[0048] The methods of generating gaps between boxes in different palletizing schemes are different.

[0049] Case (1), when ...

Abstract

The invention discloses a stacking method and a stacking device.The stacking method is used for stacking a plurality of cuboid-shaped boxes with the same size on a rectangular tray, and the method comprises the steps that length and width information of the tray is obtained, and length and width information of the boxes is obtained; the algorithm is executed, all stacking schemes meeting constraint conditions in the algorithm are obtained, and each scheme result is recorded; wherein constraint conditions in the algorithm are set according to a preset processing model; the scheme with the maximum stacking number in the obtained stacking schemes is obtained through a Umax target function, wherein the Umax target function is set according to a preset processing model; according to the stacking device, the space utilization rate of the trays can be increased, and the stacking working efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of stacking, in particular to a stacking method and a stacking device. Background technique [0002] There are often a large number of goods in the product warehouse that need to be stacked and stacked. When the goods are put on the shelf or out of the warehouse, the loose goods need to be stacked on the pallet as closely as possible in a certain way to facilitate distribution and transportation. Palletizing design is an indispensable link in product logistics and warehousing. The goal is to provide the optimal solution for placing the maximum number of boxes of a given size on the pallet. A reasonable palletizing solution can improve the utilization rate of pallets and reduce the logistics and warehousing of products. cost. At present, the palletizing design on the market still mainly relies on manual calculation to carry out the palletizing design of boxes, which is not only inefficient, but also cannot g...
