Description

[Technical Field]

[0001] This invention relates to a method for stacking and grouping sheet metal packages. [Background Technology]

[0002] In the current furniture manufacturing industry, the stacking process of incoming board packages is all done manually. In order to facilitate inventory and transportation, multiple packages of the same batch need to be divided into multiple groups for stacking. The quantity and volume of the packages in each stacking group are required to be similar. Therefore, stacking personnel are often required to have certain experience in stacking packages. However, in actual operation, manual stacking is also prone to problems such as large differences in the quantity or volume of packages stacked in each group, which causes inconvenience to inventory and transportation. [Summary of the Invention]

[0003] This invention overcomes the shortcomings of the prior art and provides a method for stacking and grouping sheet metal packages.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A method for stacking and grouping sheet metal packages, characterized in that: it includes...

[0006] S1. Read the information of each sheet metal package to obtain the total number of sheet metal packages, the volume of each sheet metal package, and the total volume of the sheet metal packages. Set the maximum number of sheet metal packages per group and the allowable value for the difference in group volume.

[0007] S2. Divide the total number of sheet metal packages into groups based on the largest number of sheet metal packages in each group to obtain the group quantity;

[0008] S3. Divide the total volume of the sheet metal package into equal groups to obtain the average volume;

[0009] S4. Divide the total number of sheet metal packages equally by the group quantity to obtain the number of sheet metal packages in each group;

[0010] S5. Group the sheet metal packages according to the quantity of each group of sheet metal packages, and ensure that the difference between the actual volume and the average volume of each group of sheet metal packages is not greater than the allowable value for the difference in group volume.

[0011] The method for stacking and grouping sheet metal packages as described above is characterized in that: when the grouping quantity value in S2 is not an integer, it is rounded up.

[0012] The method for stacking and grouping sheet metal packages as described above is characterized in that: S4 includes...

[0013] S41. Determine if the number of grouped board packages is an integer. If yes, jump to S5; otherwise, jump to S42.

[0014] S42. Set the number of sheet metal packages in a sheet metal package group to the integer value of the number of sheet metal packages in the group, and calculate the remaining number of sheet metal packages and the remaining number of groups;

[0015] S43. Divide the remaining number of board packages equally among the remaining group quantities to obtain the number of board packages in each group, then jump to S41.

[0016] The method for stacking and grouping sheet metal packages as described above is characterized in that: in S5, the sheet metal packages are grouped by the quantity of each group of sheet metal packages to obtain different combinations of sheet metal package groups, and one of the combinations is selected in which the difference between the actual volume and the average volume of each group of sheet metal packages is not greater than the allowable value of the group volume difference.

[0017] The method for stacking and grouping sheet metal packages as described above is characterized in that: in S1, the information of each sheet metal package is read, including the order number information; and in S5, sheet metal packages with the same order number are grouped into the same sheet metal package group.

[0018] The method for stacking and grouping sheet metal packages as described above is characterized in that: the information read in S1 for each sheet metal package includes the length, width and height information of the sheet metal package.

[0019] The method for stacking and grouping sheet metal packages as described above is characterized in that the maximum number of sheet metal packages in a group is 100.

[0020] The beneficial effects of this invention are:

[0021] 1. This invention sets a maximum number of sheet metal packages per group, thereby limiting the maximum number of sheet metal packages per palletizing group. The number of palletizing groups is calculated based on the maximum number of sheet metal packages per group. Then, the average volume and the number of sheet metal packages per group are calculated based on the number of groups. The delivered sheet metal packages are then grouped according to the number of sheet metal packages per group, and the difference between the actual volume and the average volume of each sheet metal package group is not greater than the allowable value for group volume difference. This makes the number and volume of sheet metal packages in each palletizing group similar, which facilitates warehousing and transportation after palletizing, saves labor, improves efficiency, speeds up the overall palletizing process, and increases the speed of logistics operations.

[0022] 2. When the group quantity value is not an integer, this invention uses rounding up. Then, it calculates the average volume and the number of board packages in each palletizing group based on the rounded group quantity value, ensuring that each palletizing group does not exceed the maximum number of board packages. At the same time, when the number of board packages in each group is calculated based on the group quantity and is not an integer, it also uses rounding up, ensuring that the difference in the maximum number of board packages between each palletizing group is one. This achieves rapid grouping and makes the number and volume of board packages in each palletizing group of the same batch of board packages similar, which facilitates warehousing and transportation after palletizing.

[0023] 3. The present invention reads the order number information of each board package, and groups board packages with the same order number into the same board package group when grouping, which makes it easy to quickly find board packages with the same order number when using them later, saving time.

[0025] The technical solutions in the embodiments of the present invention will now be clearly and completely described in conjunction with the accompanying drawings.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. Furthermore, descriptions involving "preferred," "second-best," etc., in this invention are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "preferred" or "second-best" may explicitly or implicitly include at least one of those features.

[0027] like Figure 1 As shown, a method for stacking and grouping sheet metal packages includes:

[0028] S1. Read the information of each sheet metal package to obtain the total number of sheet metal packages, the volume of each sheet metal package, and the total volume of the sheet metal packages. Set the maximum number of sheet metal packages per group and the allowable value for the difference in group volume.

[0029] S2. Divide the total number of sheet metal packages into groups based on the largest number of sheet metal packages in each group, and obtain the group quantity. If the group quantity value is not an integer, round it up.

[0030] S3. Divide the total volume of the sheet metal package into equal groups to obtain the average volume;

[0031] S4. Divide the total number of sheet metal packages equally among the group quantities to obtain the number of sheet metal packages per group. Specifically,

[0032] S41. Determine if the number of grouped board packages is an integer. If yes, jump to S5; otherwise, jump to S42.

[0033] S42. Set the number of sheet metal packages in a sheet metal package group to the integer value of the number of sheet metal packages in the group, and calculate the remaining number of sheet metal packages and the remaining number of groups;

[0034] S43. Divide the remaining number of board packages equally among the remaining group quantities to obtain the number of board packages in each group, then jump to S41;

[0035] S5. Group the board packages according to the quantity of each group of board packages, and ensure that the difference between the actual volume and the average volume of each group of board packages is not greater than the allowable value of the group volume difference. Specifically, in S5, the board packages are grouped according to the quantity of each group of board packages to obtain different combinations of board package groups. Select one combination in which the difference between the actual volume and the average volume of each group of board packages is not greater than the allowable value of the group volume difference.

[0036] In this case, S1 reads the information of each board package, including the order number information. In S5, board packages with the same order number are grouped into the same board package group, which makes it easier to quickly find board packages with the same order number when using them later, saving time.

[0037] In this case, S1 reads information about each board package, including the length, width, and height of the board package, and calculates the volume of the board package based on the length, width, and height information of the board package.

[0038] Assuming there are 342 sheet metal packages, and the maximum number of sheet metal packages per group is 100, the grouping process is as follows:

[0039] After reading the information of each sheet metal package, the total number of sheet metal packages is 242, as well as the volume information of each sheet metal package and the total volume of the sheet metal package A. The maximum number of sheet metal packages in a group is set to 100 and the allowable value for the volume difference between groups is set to B.

[0040] The total number of sheet metal packages is grouped by the largest number of sheet metal packages in the group, that is, the number of groups is 242 / 100 = 2.42. Since the number of groups 2.42 is not an integer, the number of groups is 3 after rounding up.

[0041] Divide the total volume of the sheet metal package into equal groups, and the average volume is A / 3.

[0042] Divide the total number of sheet metal packages equally among the group quantities, and the total number of sheet metal packages per group is 242 / 3 = 80.6…;

[0043] Determine if the number of board packages in the group (80.6...) is an integer; if the number of board packages in the group (80.6...) is not an integer, set the number of board packages in one group to the integer value of the number of board packages in the group. Therefore, the number of board packages in one group is 81. Calculate the remaining number of board packages: 242 - 81 = 161. The remaining number of groups is 3 - 1 = 2.

[0044] Divide the remaining number of board packages equally among the remaining group quantities, and the total number of board packages in each group is 161 / 2 = 80.5;

[0045] Determine if the number of board packages in the group is 80.5. If the number of board packages in the group is not an integer, set the number of board packages in one group to the integer value of the number of board packages in the group. Therefore, the number of board packages in one group is 81. Calculate the remaining number of board packages: 161-81=80. The remaining number of groups is 2-1=1.

[0046] Divide the remaining number of board packages equally among the remaining group quantities, and the total number of board packages in each group is 80 / 1 = 80.

[0047] Determine if the number of packaged board pieces in the group is 80; since the number of packaged board pieces in the group is 80, the number of packaged board pieces in the three palletizing groups is 81, 81, and 80 respectively.

[0048] The 242 sheet metal packages were divided into three groups based on the number of packages: 81, 81, and 80, resulting in different combinations of sheet metal package groups. Subsequently, the actual volume of each sheet metal package group in each group was calculated, and the actual volume of each sheet metal package group in each group was compared with the average volume A / 3. The group in which the difference A / 3 between the actual volume of each sheet metal package group and the average volume is not greater than the allowable value B for the difference in group volume was selected. The 242 sheet metal packages were then sorted and grouped according to this selected combination.

[0049] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct or indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
