Description
Technical Field
[0001] This invention relates to the technical field of cigarette transportation, and more specifically, to a planning method for loading finished cigarette boxes onto a vehicle. Background Technology
[0002] In the finished cigarette shipment process, the stacking of cigarette cartons in the truck is technically demanding due to considerations of cigarette quality protection and transportation stability. This includes the need for a balanced arrangement of the truck's length, width, and height, as well as the cigarette cartons, to maximize loading efficiency. Standard cigarette cartons must be stacked upright, while non-standard cartons must be stacked according to actual conditions; neither standard nor non-standard cartons should be placed sideways. Two layers of cartons can be placed horizontally on the top level of the truck. The presence of gooseneck structures in the truck must be considered during stacking. The mixed stacking of cigarette cartons of various specifications and destinations must also be taken into account. While manual loading is sufficient for workers, in the tobacco production industry, with increasing automation in production and warehousing equipment, the use of loading robots to replace manual loading of finished cigarette cartons is becoming a trend. Existing loading and stacking planning methods cannot meet these technical requirements, necessitating a loading planning method that satisfies these needs to complement the use of loading robots.

The length, width, and height of a single finished cigarette box when laid flat are as follows: Substituting into steps 4-1-1-1 and 4-1-1-2, we get and To obtain the stacking method of a single type of finished cigarette box in the flat stacking area; Step 4-1-3: Calculate the length as The maximum number of cigarettes that can be stacked within the designated area for: ； Step 5: Substitute the information of the current type of finished cigarette box in the current order group into the calculation model of the single finished cigarette box stacking method in Step 4 to obtain the stacking method. If the current type of finished cigarette box in the current order group can be stacked into a cuboid when stacked in this method, stack it into a cuboid first in this method, and then update the remaining quantity of the current type of finished cigarette box in the current order group and the remaining space size in the carriage; otherwise, proceed to Step 9. Step 6: If the remaining quantity of the current type of finished cigarette box in the current group order updated in Step 5 is not 0, return to Step 5; otherwise, proceed to Step 7. Step 7: If there is no remaining space in the carriage or the current type of finished cigarette box in the current order is the last type of finished cigarette box in the last order, end the planning; otherwise, proceed to step 8. Step 8: When the current type of finished cigarette box in the current order group is the last type of finished cigarette box in the current order group, select any type of finished cigarette box in the next order group as the current type of finished cigarette box in the current order group, and return to Step 5; otherwise, select any remaining type of finished cigarette box in the current order group as the current type of finished cigarette box in the current order group, and return to Step 5. Step 9: If the remaining finished cigarette boxes of the current type in the current order are stacked in a row according to the usual stacking method, then the remaining finished cigarette boxes of the current order are stacked in the usual stacking method and the process returns to Step 7; otherwise, proceed to Step 10. Step 10: Using the calculation model of the matching degree of the two types of finished cigarette boxes and the corresponding stacking methods in Step 4, calculate the matching degree of the current type of finished cigarette box in the current group of orders with all types of finished cigarette boxes that can be used as the next loading. Select the one with the highest matching degree as the next loading type of finished cigarette box, obtain the corresponding stacking method, stack the current type of finished cigarette boxes in the current group of orders in this stacking method, and continue to stack the next loading type of finished cigarette boxes in this stacking method until a whole row is formed. Update the remaining quantity of the next loading type of finished cigarette boxes and the size of the remaining space in the carriage. Use the remaining next loading type of finished cigarette boxes as the current type of finished cigarette boxes in the current group of orders, and return to Step 5.
2. The planning method for loading finished cigarette boxes onto a vehicle according to claim 1, characterized in that: Step 4 further includes step 4-2: constructing a calculation model for the matching degree of the two finished cigarette boxes and the corresponding stacking methods: ， in, , These represent the length and width of the first type of finished cigarette box, respectively. This indicates the number of the first type of finished cigarette boxes stacked horizontally in a horizontal row. This indicates the number of the first type of finished cigarette boxes stacked vertically in a horizontal row. , These represent the length and width of the second type of finished cigarette box, respectively. This indicates the number of the second type of finished cigarette boxes stacked horizontally in a horizontal row. This indicates the number of the second type of finished cigarette boxes stacked vertically in a horizontal row. Indicates the maximum allowable gap; This indicates the stacking stroke of the cigarette loading machine in the forward and backward direction.
3. The planning method for loading finished cigarette boxes onto a vehicle according to claim 2, characterized in that: Step 10 includes the following steps: Step 10-1: When the current type of finished cigarette box in the current order group is the last type in the current order group, use the calculation model of the matching degree of the two types of finished cigarette boxes and the corresponding stacking method in Step 4 to calculate the matching degree of the current type of finished cigarette box in the current order group with all types of finished cigarette boxes in the next order group. Select the one with the highest matching degree as the next type of finished cigarette box to be loaded, and obtain the corresponding stacking method. If yes, proceed to step 10-3; otherwise, proceed to step 10-2. Step 10-2: Using the matching models of the two types of finished cigarette boxes and their corresponding stacking methods from Step 4, calculate the matching degree between the current type of finished cigarette box in the current order group and the remaining types of finished cigarette boxes in the current order group. Select the one with the highest matching degree as the next type of finished cigarette box to be loaded, and obtain the corresponding stacking method. Proceed to step 10-3; Step 10-3: The current type of finished cigarette box in the current order group is processed according to... The stacking method is as follows: the next type of finished cigarette box for loading is... Continue stacking in the same way until a whole row is formed. Update the remaining quantity of the cigarette box for the next type of loading and the dimensions of the remaining space in the carriage. Proceed to step 10-4. Step 10-4: When the remaining quantity of the next loading type of finished part smoke box is 0, return to step 7; otherwise, use the remaining next loading type of finished part smoke box as the current type of finished part smoke box for the current group order, and return to step 5.
4. The planning method for loading finished cigarette boxes onto a vehicle according to claim 3, characterized in that: Step 10-3 includes the following steps: Step 10-3-1: The current type of finished cigarette box in the current order group is processed according to... The stacking method is as follows: when the current type of finished cigarette boxes for the current order group are stacked to form a whole layer, the next type of finished cigarette boxes for loading will be stacked in the following manner. The stacking method starts on the entire layer and continues until the entire row is completed. Update the remaining quantity of the cigarette boxes for the next type of loading and the dimensions of the remaining space in the carriage, and proceed to step 10-4; otherwise, proceed to step 10-3-2. Step 10-3-2: Divide the entire floor above into two parts. The next type of finished part smoke box will be placed in each of the two parts.
