Example Embodiment

[0036] The technical solutions of the present invention will be further described below in conjunction with the drawings and specific implementations.

[0037] Such as Figure 1-Figure 3 As shown, an online cargo palletizing method with insufficient information includes the following steps:

[0038] Step 1: Determine whether the space of the pallet in each two-dimensional plane parallel to the bottom surface of the pallet can accommodate the goods to be placed a 1 , If not possible, the goods a 1 Place it in the next pallet; if possible, judge whether the height of the pallet can accommodate the goods to be placed a 1 , If not possible, the goods a 1 Place it in the next tray, if possible, record the position 1 Go to location collection L;

[0039] Step two, judge each position l i Place the goods to be placed a 1 Time and goods a 1 Is the contact area at the bottom of the i Delete, if it is satisfied, continue to judge whether there is an obstacle in the vertical direction at this p...

Abstract

The invention relates to an on-line cargo stacking method based on under-complete information. The on-line cargo stacking method based on the under-complete information is characterized by comprisingthe following steps that 1, all positions l capable of accommodating cargoes are recorded into a position set L; 2, screening is carried out according to whether the contact area between each position l and the bottom of the corresponding cargo a<1> meets a safe placement requirement or not when the corresponding cargo a<1> to be placed is placed and whether obstacles exist in the vertical direction or not; 3, corresponding placement positions of all the cargoes are found, an average value m<1> of the number of trays required by all schemes is recorded, a Monte Carlo sampling method is used for calculating a corresponding average number m of trays needed when the corresponding cargo a<1> is placed at each position l, and the minimum value in m is selected; and 4, the step 1to the step 3 are repeated till stacking of all the cargoes is completed. The method can effectively improve a space utilization rate of the trays.

Description

technical field [0001] The invention relates to the technical field of cargo palletizing, in particular to an online cargo palletizing method with incomplete information. Background technique [0002] At present, the palletizing schemes studied in our country are all based on offline palletizing schemes, which is to design a scheme that maximizes the utilization rate of pallets and minimizes the number of pallets used under the premise of knowing the type, quantity, and order of goods. Today, with the development of intelligence and automation, this offline solution needs to be optimized and changed to adapt to new problems. [0003] During the assembly line robot palletizing operation, we may only know the type and size of the goods, but not the order of the goods coming from the assembly line. In this case, we can only rely on the experience of the workers for manual palletizing, but when the goods are slightly larger or When it is slightly heavier, it has to be operated ...
