Description

Technical Field

[0001] The present invention belongs to the technical field of logistics management, and particularly relates to a loading calculation method for multi-specification packaging boxes. Background Art

[0002] In recent years, the specifications of finished cigarettes have changed greatly, and there are various specifications such as conventional finished cigarettes, medium-sized cigarettes, slender cigarettes, and manually packaged cigarettes. When loading multi-specification finished cigarettes, it is very difficult to calculate whether the transport vehicle can hold the finished products to be sent. There are often situations where the vehicle needs to be replaced and reloaded because the finished products cannot be loaded, which is time-consuming and laborious.

[0003] Currently, it is mainly through manual calculation to roughly estimate whether a certain number of multi-specification finished cigarettes can be loaded, and then start loading. Because manual estimation is inefficient, the more specifications there are, the more difficult it is to estimate, and the estimation result is not intuitive, making it difficult to evaluate whether the estimation result meets the loading requirements. Therefore, an algorithm for loading multi-specification cigarette products is needed to calculate in advance whether the loading vehicle can hold the cigarette products to be sent, so as to improve the efficiency of shipping cigarette products. Summary of the Invention

[0004] The purpose of the present invention is to provide a loading calculation method for multi-specification packaging boxes to solve the problem of the deficiency of the existing loading algorithms for multi-specification cigarette products and the inability to estimate the loading of multi-specification cigarette products. At the same time, the loading strategy is formed into a three-dimensional visualization effect to facilitate the loading operation of the loading personnel.

[0005] To achieve the above purpose, the present application is implemented through the following technical solutions:

[0006] A loading calculation method for multi-specification packaging boxes includes the following steps:

[0007] S1. Stack the packaging boxes of different specifications in advance to form multiple different combination modules, including vertical combination modules and horizontal combination modules;

[0008] S2. Calculate the maximum number of layers of packaging boxes that can be loaded in the vertical direction according to the maximum loadable height of the carriage;

[0009] S3. According to the different vertical combination modules in step S1, calculate the corresponding vertical combination modes obtained for the packaging boxes in the top two layers according to different combination modules when calculating according to the carriage height in step S2, and the remaining layers are all placed vertically to improve the compressive capacity of the packaging boxes;

[0010] S4. By calculating the cumulative height of the packaging boxes in different vertical combination modes, select the vertical combination mode whose cumulative height is closest to and does not exceed the maximum loadable height of the carriage;

[0011] S5. According to the width, length of the carriage and the vertical patterns of each layer, and based on the horizontal combination modules in step S1, obtain the horizontal combination patterns, calculate the number of packing boxes that can be placed on each layer, and select the horizontal combination pattern with the largest number of packing boxes that can be placed.

[0012] S6. After determining the vertical combination pattern and the horizontal combination pattern according to steps S5 and S6, calculate the maximum number that can be placed according to the length and width of the carriage, and allocate the number of each layer of the packing boxes to be loaded proportionally based on this number.

[0013] S7. According to step S6 and following the principle of last-in, first-out, load the packing boxes of different specifications and quantities respectively.

[0014] Further, the vertical combination modules in step S1 at least include the vertical combination modules of 1 vertical, 1 modular and 1 flat, and the vertical combination modules of 2 horizontal and 2 flat; the horizontal combination modules include the forward horizontal combination modules and the lateral horizontal combination modules.

[0015] Further, in step S5, the number of packing boxes = (carriage length / packing box length) × (carriage width / packing box width), and the horizontal combination modules include two types of modules, forward and lateral. When the length and width of the packing box are interchanged, the obtained number of packing boxes is different, and thus the placement pattern in the horizontal direction of this layer is obtained.

[0016] Further, in step S6, the number of packing boxes on each layer = the total number of packing boxes of this specification × (carriage length / packing box length of this layer × carriage width / packing box width of this layer) / the sum of the number of packing boxes that can be placed on each layer.

[0017] Further, in step S6, after calculating the number of packing boxes on each layer, if there is a remainder, the remaining packing boxes are newly added according to the placement pattern of the bottom layer. If the bottom layer is not enough, they are placed in the penultimate layer, the third layer from the bottom in turn, and so on.

[0018] Further, it also includes forming a loading calculation model according to the loading calculation method of any one of the above and respectively preparing three-dimensional visualization effect diagrams.

[0019] The beneficial effects of the present invention are:

[0020] This technical solution greatly improves the estimation efficiency and scientificity of loading cigarette finished products, avoids the problem of finding that it cannot be loaded after loading and then changing the vehicle. At the same time, it also provides a loading strategy for convenient loading operation, greatly improving the loading efficiency. Specific embodiments

[0021] The technical solution of the present invention will be described in detail through the following embodiments. The following embodiments are only exemplary and can only be used to explain and illustrate the technical solution of the present invention, rather than being construed as a limitation on the technical solution of the present invention.

[0022] This technical solution mainly aims at a loading algorithm for multi-specification packaging boxes to solve the pre-calculation problem of loading. In the following embodiments of this application, taking cigarette boxes as an example, the pre-calculation of loading the packaging boxes will be described in detail. It does not mean that this technical solution is only applicable to cigarette boxes, but this technical solution is applicable to the pre-calculation of loading all relevant packaged goods in the logistics field. For example, packaging boxes of different models of refrigerators, air conditioners, etc. can all be applicable to the technical solution of this application.

[0023] In the following embodiments, since there are different models of cigarette boxes for current cigarettes, such as cigarette boxes for regular cigarettes, medium-sized cigarettes, slender cigarettes, or manually packaged cigarettes, etc., usually the specification sizes of these different models of cigarette boxes are completely different, or the cigarette boxes of the same model but different brands of cigarettes may also be different. When transporting outwards, it cannot be guaranteed that the same vehicle only transports the same model of cigarette boxes. Most of the time, the same vehicle needs to transport multiple models of cigarette boxes to a specific location at the same time, which is the basis for the implementation of this technical solution.

[0024] In the technical solution of this application, taking the cigarette box as a cuboid structure as an example for illustration, where the vertical direction of the cigarette box is the height of the cigarette box, the horizontal direction of the cigarette box is the width of the cigarette box, and the flat direction of the cigarette box is the length of the cigarette box. Any specification of the cigarette box will be described accordingly.

[0025] S1. Pre-form multiple different combination modules for stacking cigarette boxes of different specifications. In the technical solution of this application, different combination modules include vertical combination modules and horizontal combination modules.

[0026] In this embodiment, taking cigarette boxes of different specifications, namely cigarette box A for regular cigarettes, cigarette box B for medium-sized cigarettes, and cigarette box C for slender cigarettes, as examples for illustration.

[0027] The vertical combination modules at least include vertical combination modules of 1 vertical, 1 module, and 1 flat, and vertical combination modules of 2 horizontal and 2 flat; the horizontal combination modules include a positive horizontal combination module and a lateral horizontal combination module.

[0028] S2. In this embodiment, first, take the cigarette case A of conventional cigarettes as an example for illustration. First, calculate the maximum number of layers that the packaging box can be loaded in the vertical direction according to the maximum loadable height of the carriage. Here, assume that the vertical height of the cigarette case A of conventional cigarettes is 500 mm, and the maximum loadable height of the carriage is 5000 mm, that is, the maximum number of layers of the packaging box A in the vertical direction is 10 layers. The same applies to other cigarette cases. For example, the vertical height of the cigarette case B of medium-sized cigarettes is 400 mm, then the maximum number of layers of the packaging box B in the vertical direction is 12 layers. The vertical height of the cigarette case C is 600 mm, then the maximum number of layers of the packaging box C in the vertical direction is 8 layers.

[0029] S3. In the technical solution of this application, it is possible to start calculating from the bottom layer which combination module to use for placement on each layer until the top layer. In this embodiment, for the cigarette case A, the first 8 layers from bottom to top are all placed vertically to enhance the compressive capacity of the cigarette case A. For the vertically placed cigarette case A, it is possible to choose the forward horizontal or lateral horizontal direction according to needs, which can be determined according to the width of the carriage.

[0030] S4. Calculate the different placement modes of the top two layers, that is, the 9th and 10th layers. By calculating the cumulative height of each placement mode, the cumulative height of this application is the total height of the following 8 layers plus the total height of the top two layers. Finally, select the placement mode that is closest to the maximum loadable height of the carriage but does not exceed the full vertical stacking of the carriage as the placement mode of the box body A.

[0031] S5. According to the width, length of the carriage and the vertical modes of each layer, calculate whether to use the forward horizontal or lateral horizontal direction placement mode to place the most box bodies. The number of box bodies per layer = (length of the carriage / length of the box body A) × (width of the carriage / width of the box body A). Because there are two placement modes of forward horizontal or lateral horizontal, at this time, the length and width of the box body are interchanged, and the number of box bodies obtained is not equal. Based on this, the placement mode in the horizontal direction of each layer can be obtained. The same calculation method is used for other box bodies B or box bodies C.

[0032] S6. For the box body A, after determining the horizontal placement mode of the following 8 layers and the vertical placement mode of the upper two layers, determine the number of box bodies A to be packed. If the number of box bodies A to be packed is greater than the maximum loadable number of the carriage, then load the vehicle in this way. If the number of box A to be packed is less than the maximum loadable number of the carriage, then calculate the maximum number that can be placed according to the length and width of the carriage. Determine the number of box bodies A to be loaded on each layer through the ratio of the number of box bodies A to be packed to the maximum number that can be placed.

[0033] After calculating the number of cases A to be packed in each layer, if there is a remainder, the remaining cases A are added row by row according to the placement pattern of the bottom layer. If one layer is not enough, they are placed in the second-to-last layer, the third-to-last layer, and so on, until all cases A are placed. The same method for placing cases A is used for other cases B or cases C to be packed.

[0034] Specifically, after placing the cases B to be packed according to the corresponding placement pattern, determine the placement pattern of cases B. Since the maximum number of vertical layers for cases B is 12, first determine the placement method for the bottom 10 layers. According to the method of cases A, when determining whether to place them horizontally forward or horizontally sideways, find the placement pattern that can accommodate the largest number of cases B. Then calculate the different placement patterns for the top two layers, i.e., the 11th and 12th layers. By calculating the cumulative height of each placement pattern, the cumulative height in this application is the total height of the bottom 10 layers plus the total height of the top two layers. Finally, select the placement pattern of full vertical stacking that is closest to the maximum installable height of the carriage but does not exceed the carriage as the placement pattern of cases B. Here, it is assumed that the number of cases B to be packed is less than the maximum installable number of the carriage for illustration. Then, calculate the maximum number that can be placed based on the length and width of the carriage. Determine the number of cases B to be packed in each layer by the ratio of the number of cases B to be packed to the maximum number that can be placed.

[0035] After calculating the number of cases B to be packed in each layer, if there is a remainder, the remaining cases B are added row by row according to the placement pattern of the bottom layer. If one layer is not enough, they are placed in the second-to-last layer, the third-to-last layer, and so on, until all cases B are placed. The same method is used for placing cases C, and no repeated description will be given here.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
