Abstract
Description
Technical Field
[0001] This invention relates to the technical field of packaging carton packing, and more specifically, to a flexible centralized packing method. Background Technology
[0002] For parts export, parts need to be packaged in cartons, and then these cartons are loaded into metal crates for export. A crucial task is packing the parts into the crates according to the customer's schedule, quantity, and the parts' own packaging specifications. The quality of packing determines the loading rate, which directly affects the customer's transportation efficiency and costs. Traditional packing methods still rely heavily on manual experience, with workers manually arranging cartons based on size and weight. While some packing system algorithms exist to generate packing plans, most are based on simple requirements such as volume priority, weight priority, and customer order requirements. This results in low space utilization in the generated packing plans. Gaps easily occur when mixing cartons of different sizes, and the stack height of the metal crates is not fully utilized. Furthermore, due to the diverse sizes of cartons, when mixing cartons that do not perfectly fit the crate size, space overflow can easily occur when switching between different sizes, frequently requiring on-site inspection and rework, resulting in low packing efficiency. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of existing parts cartons in which the internal space is not fully utilized when mixed packing, and to provide a flexible centralized packing method that can improve packing loading rate and packing efficiency through rule matching, sequence optimization and compensation adjustment.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A flexible centralized packing method is provided, comprising the following steps: S1. Group all the parts packaging cartons; S2. Establish packing rules for frequently ordered parts; S3. Establish priority rules; wherein, step S3 includes: S31. Set basic priority rules; S32. Set the first priority rule: classify the parts packaging cartons, and then pack the parts packaging cartons into the metal frame boxes according to the group and category; S33. Set a second priority rule: mix the same group in the same layer and unrestricted groups between different layers; when switching between packaging cartons of different groups of parts between layers, set a height compensation value and load the packaging cartons of different groups of parts in sequence based on the height compensation value; S34. Set a third priority rule: Mix and pack in a way that does not restrict the group between the same layer and between different layers; within the same layer, set a same-layer mixing rule, and load the packaging cartons of different groups of parts in sequence based on the same-layer mixing rule; between different layers, load the packaging cartons of different groups of parts in sequence based on the height compensation value. S4. Count the number of packaging cartons for each group of parts in real time to obtain the remaining quantity of unpacked cartons; based on the group of packaging cartons for each group of parts and the remaining quantity of unpacked cartons, pack them first according to the rules in step S2, and then select the appropriate rules for packing in step S3.
[0005] This invention provides a flexible centralized packing method that, by establishing packing rules for frequently ordered parts, prioritizes and solidifies high-frequency order schemes, thereby improving packing efficiency. Through the established priority rules, when mixing parts, the method addresses the issue of layer height adaptation of packaging cartons of different heights within the metal frame box using height compensation values. Furthermore, it avoids the risk of overflow during mixed packing by setting rules for mixing parts within the same layer. This invention improves packing loading rate and packing efficiency through rule matching, sequence optimization, and compensation adjustment.
[0006] Furthermore, in step S3, the basic priority rule has a higher priority than the first priority rule, the second priority rule, and the third priority rule; in step S31, the basic priority rule is: smaller does not suppress larger, and heavier does not suppress lighter.
[0007] Further, step S32 includes the following steps: S321. Classify each group of parts packaging cartons, including: standard parts packaging cartons and non-standard parts packaging cartons; S322. For standard parts packaging cartons, pack them into iron frame boxes according to their groups, and ensure that each iron frame box is in a standard full-load state; S323. For non-standard parts packaging cartons, pack them into iron frame boxes according to their groups, and ensure that each iron frame box is in a non-standard full-load state.
[0008] Further, in step S33, the height compensation value is set to... ,in: = / T In the formula, This indicates the maximum remaining height space in the metal frame box after the parts packaging cartons are packed. T This indicates the height of the metal frame box.
[0009] Further, in step S33, The calculation formula is:
[0010]
[0011] In the formula, T Indicates the height of the iron frame box. s Non-negative integer combinations representing the height of the parts packaging carton; Indicates the first i The number of layers in the cardboard box for packaging parts within the metal frame box; Indicates the first i The height of the cardboard box used for packaging the parts.
[0012] Further, in step S34, the same-layer mixing rule includes: Set the packing direction and packing order of the parts packaging cartons in the iron frame box within the same group: Place the parts packaging cartons one by one in the iron frame box along the width direction of the iron frame box; when the current width position of the iron frame box is full, move it along the length direction of the iron frame box and then place it one by one along the width direction of the iron frame box. Set the packing order for parts packaging cartons between different groups: sort the parts packaging cartons from smallest to largest area; Set the packing position of the parts packaging cartons between different groups: after shifting along the length of the iron frame box from the end position of the previous group of parts packaging cartons, place the next group of parts packaging cartons. Calculate the actual number of parts packaging cartons placed in the current layer for each group.
[0013] Furthermore, the actual number of parts packaging cartons placed in the current layer of the iron frame box within each group is set as follows: ,in: = min( , ) =
[0014] = floor(( ) / ) = floor( W / ) In the formula, L Indicates the length of the iron frame box. W This indicates the width dimension of the metal frame box. Indicates the first i The length dimensions of the packaging carton for the assembled parts. Indicates the first i Width dimensions of the cardboard box used for packaging the parts. This indicates the coordinates of the farthest point of the current part's packaging carton along the length direction within the current layer; Indicates the coordinate position Below, the number of cartons containing the group of parts that can still be placed along the length of the current layer; floor indicates rounding down; This indicates the maximum number of cartons containing this group of parts that can be placed in the current layer along the width direction; This indicates the maximum number of cartons containing this group of parts that can be placed in the current layer; Indicates the first i Quantity of cartons used for packaging parts; if If the value is greater than 0, then update the coordinate position. (+), where: (+)=
[0015] In the formula, ceil represents rounding up.
[0016] Furthermore, in step S1, each group of parts packaging cartons contains parts packaging cartons of the same type and the same carton size.
[0017] Furthermore, in step S2, the packing rules for the high-frequency ordered parts include: Set high-frequency repackaging rules: Sort the order frequency of each part in the historical parts ordering records from most to least frequent. For the parts ordered first... n The parts packaging cartons corresponding to the parts number are matched one by one with standard or non-standard iron frame boxes according to their respective carton sizes, so that the iron frame boxes are in a standard full-load state or a non-standard full-load state after packing. Set high-frequency mixed-item rules: For items sorted first... n The part packaging cartons corresponding to the part types of serial numbers are determined according to the size of their respective cartons. The group of iron frame boxes of each specification size that can be mixed and packed and the corresponding number of cartons are determined, so that the packed iron frame boxes are in a standard full-load state or a non-standard full-load state. The high-frequency packaging rule has a higher priority than the high-frequency mixing rule.
[0018] Furthermore, the flexible centralized packing method further includes step S5: Check whether the iron frame boxes packed according to the second priority rule and the third priority rule have overflow. Check whether the gross weight of the steel frame boxes packed according to the first priority rule, the second priority rule, and the third priority rule exceeds the load-bearing requirements of the steel frame boxes.
[0019] Compared with the prior art, the beneficial effects of the present invention are: By establishing high-frequency order parts packing rules, high-frequency order solutions can be prioritized, improving packing efficiency. Priority rules, when handling mixed packing, address the issue of layer height compatibility between cartons of different heights within the metal frame box using height compensation values. Furthermore, rules for mixing within the same layer can prevent overflow risks. This invention improves packing loading rate and efficiency through rule matching, sequence optimization, and compensation adjustments. After packing, checking for overflow and excessive gross weight within the metal frame box further prevents overflow risks and enhances operational safety. Attached Figure Description

[0022] The present invention will be further described below with reference to specific embodiments. To enable those skilled in the art to better understand the present invention, the technical solutions of the embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.
[0023] Those skilled in the art will understand that embodiments of the present invention can be provided as methods, systems, or computer program products. Therefore, the present invention can take the form of a completely hardware embodiment, a completely software embodiment, or an embodiment combining software and hardware aspects.
[0024] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this invention are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.
[0025] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0026] Example 1 like Figure 1 The first embodiment of a flexible centralized packing method of the present invention is shown, which includes the following steps: S1. Group all the parts packaging cartons; S2. Establish packing rules for frequently ordered parts; S3. Establish priority rules; wherein, step S3 includes: S31. Set basic priority rules; S32. Set the first priority rule: classify the parts packaging cartons, and then pack the parts packaging cartons into the iron frame box 200 according to the group and category; S33. Set a second priority rule: mix the same group of parts on the same layer and unrestricted groups between different layers; when switching between packaging cartons of different groups of parts between layers, set a height compensation value and load the packaging cartons of different groups of parts in sequence based on the height compensation value. S34. Set the third priority rule: Mix and pack in a way that does not restrict the group between the same layer and between different layers; within the same layer, set the same layer mixing rule, and load the packaging cartons of different groups of parts in sequence based on the same layer mixing rule; between different layers, load the packaging cartons of different groups of parts in sequence based on the height compensation value. S4. Count the number of packaging cartons for each group of parts in real time to obtain the remaining quantity of unpacked cartons; based on the group of packaging cartons for each group of parts and the remaining quantity of unpacked cartons, pack them first according to the rules in step S2, and then select the appropriate rules for packing in step S3.
[0027] By establishing high-frequency order parts packing rules, high-frequency order solutions can be prioritized, improving packing efficiency. Furthermore, by establishing priority rules, when mixing parts, the height compensation value within the priority rules can address the issue of matching the layer height of cartons of different heights within the metal frame box. Additionally, the established same-layer mixing rules can prevent the risk of overflow during mixing. This invention can improve packing loading rate and packing efficiency through rule matching, sequence optimization, and compensation adjustment.
[0028] Example 2 This embodiment is a second embodiment of a flexible centralized packing method. This embodiment is similar to the first embodiment, except that, as shown in the following... Figures 2 to 7 As shown, specifically, in step S1, all received parts packaging cartons are grouped, specifically by the type of parts loaded in the cartons and the size of the cartons, so that each group of parts packaging cartons contains parts packaging cartons of the same type and the same size. It should be noted that parts of the same type are loaded using parts packaging cartons of the same size; different types of parts are generally loaded using parts packaging cartons of different sizes, but there are still cases where different types of parts are loaded using parts packaging cartons of the same size.
[0029] Specifically, in step S2, the packing rules for frequently ordered parts include: Set high-frequency repackaging rules: Sort the order frequency of each part in the historical parts ordering records from most to least frequent. For the parts ordered first... n The part packaging cartons corresponding to the part types of serial numbers are matched one by one with the standard or non-standard iron frame boxes 200 according to their respective carton sizes, so that the iron frame boxes 200 after packing are in a standard full-load state or a non-standard full-load state. Set high-frequency mixed-item rules: For items sorted first... nThe packaging cartons corresponding to the part types of serial numbers are determined according to the size of each carton, and the group and the corresponding number of cartons that can be mixed and packed in the iron frame boxes 200 of each specification are determined, so that the packed iron frame boxes 200 are in a standard full-load state or a non-standard full-load state. The high-frequency packaging rule has a higher priority than the high-frequency mixing rule.
[0030] In this embodiment, the standard fit between the cardboard box size of the parts packaging cartons and the specifications of the metal frame box 200 means that after the parts packaging cartons are stacked in the metal frame box 200 of the specified size at the maximum capacity, the parts packaging cartons can fit snugly inside the metal frame box 200, and at this time, a standard full-load state is achieved. (Refer to...) Figure 2 The state shown, where the load rate 92%; The non-standard fit between the cardboard box size and the metal frame box 200 means that when the cardboard boxes are stacked at their maximum capacity inside the metal frame box 200, the cardboard boxes fit snugly against the interior of the metal frame box 200, reaching a non-standard full-load state. (See reference for details.) Figure 3 The indicated state shows a loading rate of 81% to 92%. It should be noted that the standard full-load state or non-standard full-load state in the high-frequency mixed-loading rule is consistent with the state indication in the high-frequency separate-loading rule. In this embodiment, the front... n The specific value of the serial number can be selected according to the actual usage scenario.
[0031] Specifically, in step S3, the basic priority rule has a higher priority than the first priority rule, the second priority rule, and the third priority rule; in step S31, the basic priority rule is: smaller should not be placed on top of larger ones, and heavier should not be placed on top of lighter ones. It should be noted that in the basic priority rule, "large" and "small" refer to the horizontal area of the parts packaging carton, while "heavy" and "light" refer to the weight of the parts packaging carton. By setting the rule of "smaller should not be placed on top of larger ones," stress concentration in the carton can be avoided, preventing damage to the cartons stacked below. It should also be noted that the basic priority rule can be added or removed according to the actual usage scenario.
[0032] In this embodiment, the iron frame boxes 200 used in step S3 can all be set to the same specifications and dimensions. Specifically, step S32 includes the following steps: S321. Classify each group of parts packaging cartons, including: 110 standard parts packaging cartons and 120 non-standard parts packaging cartons; wherein: Standard parts packaging carton 110 refers to a carton that, when stacked in a metal frame box 200 with the maximum number of cartons it can hold, can fit snugly against the interior of the metal frame box 200; non-standard parts packaging carton 120 refers to a carton that, when stacked in a metal frame box 200 with the maximum number of cartons it can hold, can fit close to the interior of the metal frame box 200. S322. For standard parts packaging cartons 110, pack them into iron frame boxes 200 according to their groups, ensuring that each iron frame box 200 is in a standard full-load state; such as Figure 2 As shown, under standard full-load conditions, standard parts packaging cartons 110 stacked in the iron frame box 200 fit snugly against the interior of the iron frame box 200, achieving a loading rate of [missing information]. 92%; S323. For non-standard parts packaging cartons 120, pack them into iron frame boxes 200 according to their groups, ensuring that each iron frame box 200 is in a non-standard full-load state; such as Figure 3 As shown, under non-standard full-load conditions, the non-standard parts packaging cartons 120 stacked in the iron frame box 200 are close to the inside of the iron frame box 200, with a loading rate of 81%~92%.
[0033] Specifically, in step S33, the height compensation value is set to... ,in: = / T
[0034]
[0035] In the formula, This indicates the maximum remaining height space in the 200mm metal frame box after the parts packaging cartons are packed. T Indicates the height of the iron frame box. s Non-negative integer combinations representing the height of the parts packaging carton; Indicates the first i The number of layers in the cardboard box for packaging the parts within the 200mm iron frame box. and It is an integer; Indicates the first i The height of the cardboard box used for packaging the parts.
[0036] like Figure 5 As shown, assuming When you need to get from height a The packaging carton for the parts has been switched to height b When assembling parts into packaging cartons,a Groups and b Interlayer mixing of the group has such Figure 5 The three scenarios shown are based on the maximum remaining height space of the iron frame box 200 after interlayer mixing. Perform height compensation value The calculation can prevent the phenomenon of floor height overflow when mixing different types of materials.
[0037] Specifically, in step S34, the same-layer mixed-packing rules include: The packing direction and order of the parts packaging cartons in the same group within the metal frame box 200 are set as follows: the parts packaging cartons are placed one by one along the width direction of the metal frame box 200, that is, rotation is not considered when the parts packaging cartons are placed in the metal frame box 200; after the current width position of the metal frame box 200 is filled, it is moved along the length direction of the metal frame box and then placed one by one along the width direction of the metal frame box; for example... Figure 6 and Figure 7 As shown, a Packaging cartons for parts In the width direction along the iron frame box 200 Place them one by one along the width direction; Set the packing order for parts packaging cartons from different groups: sort them according to the area of the parts packaging cartons from smallest to largest; for example... Figure 6 and Figure 7 As shown, a The area of the packaging carton for the parts ( ) b The area of the packaging carton for the parts ( Therefore, proceed first. a The packaging of parts into cartons is done in the same way; Set the packing position of the parts packaging cartons between different groups: After shifting along the length of the metal frame box from the end position of the previous group of parts packaging cartons, place the next group of parts packaging cartons; for example... Figure 6 and Figure 7 As shown, after placement a After assembling the parts and packaging them into cartons b The packaging boxes for all the parts were placed starting from the coordinate position of y=0; Calculate the actual number of parts packaging cartons placed in the current layer for each group, including the following calculations: Set the actual number of parts packaging cartons placed in the current layer of the 200-cell metal frame box for each group. ,in: = min( , ) =
[0038] = floor(( ) / ) = floor( W / ) In the formula, L This indicates the length of the 200mm iron frame box. W This indicates the width dimension of the 200mm iron frame box. Indicates the first i The length dimensions of the packaging carton for the assembled parts. Indicates the first i Width dimensions of the cardboard box used for packaging the parts. This indicates the coordinates of the farthest point of the current part's packaging carton along the length direction within the current layer; Indicates the coordinate position Below, the number of cartons containing the group of parts that can still be placed along the length of the current layer; floor indicates rounding down; This indicates the maximum number of cartons containing this group of parts that can be placed in the current layer along the width direction; This indicates the maximum number of cartons containing this group of parts that can be placed in the current layer; Indicates the first i Quantity of cartons used for packaging parts; if If the value is greater than 0, then update the coordinate position. (+), where: (+)=
[0039] In the formula, ceil represents rounding up; if If the current layer is full, it means that no more space can be placed on it and another layer needs to be added until there is not enough space inside the 200 iron frame box.
[0040] It should be noted that in step S2, the dimensions of the iron frame boxes 200 of each specification are known quantities; the length of the iron frame boxes 200 used in step S3 is... L ,width W ,high T All quantities are known, including the length of the packaging carton for each group of parts. ,width ,high All of these are known quantities; therefore, by calculating the volume and area, we can determine the maximum number of cartons that can be held for each type of part corresponding to the iron frame box 200 of each specification and size when packing according to the high-frequency packing rules in step S2. , , ...; it can also know the maximum number of cartons that can be held for each type of part packaging carton corresponding to each size of the iron frame box 200 when packing according to the high-frequency mixed packing rule in step S2; it can also know the loading rate of each group of part packaging cartons in the iron frame box 200 in step S3; it can also know the maximum number of cartons that can be held for each group of part packaging cartons in the iron frame box 200 in step S3. , , ...; it can also be determined that in step S3, the maximum number of cartons that can be placed in each layer of the iron frame box 200 for each group of parts packaging cartons can be determined. , , ...
[0041] Therefore, in step S4, the part types corresponding to all part packaging cartons are first identified. For part packaging cartons belonging to the part types corresponding to the high-frequency ordering part packing rules, the remaining quantity of unpacked cartons is determined. The corresponding maximum number of boxes that can be accommodated At that time, packing is carried out according to the high-frequency packing rules in step S2; and for the remaining quantity that is not packed... The corresponding maximum number of boxes that can be accommodated However, if the high-frequency mixed packing rule can be met, packing is carried out according to the high-frequency mixed packing rule in step S2. After each packing of the iron frame box 200 is completed, the remaining quantity of unpacked boxes in the groups with quantity changes is statistically updated, and then the appropriate rule is selected in step S2 to continue packing based on the updated remaining quantity of unpacked boxes.
[0042] Therefore, in step S4, the remaining parts packaging cartons after packing according to the rules in step S2, as well as parts packaging cartons from other groups that do not belong to the high-frequency order parts packing rules, are handled as follows: Unpacked remaining quantity Maximum number of boxes and loading rate 81% of the groups were packed according to the rules in step S32; after packing, as follows... Figure 2 and Figure 3 As shown; Unpacked remaining quantity Maximum number of boxes and loading rate 81% of the groups were packed according to the rules in step S33; Unpacked remaining quantity Maximum number of boxes And the remaining quantity not packed Maximum number of boxes that can be accommodated in one floor The groups are categorized and packed according to the rules in step S33; after packing, as follows... Figure 4 As shown; Unpacked remaining quantity Maximum number of boxes that can be accommodated in one floor The groups are categorized and packed according to the rules in step S34; after packing, as follows... Figure 6 or Figure 7 As shown. Similarly, after each packing of 200 iron frame boxes is completed, the remaining quantity of unpacked boxes in groups with quantity changes is statistically updated. Then, based on the updated remaining quantity of unpacked boxes, the appropriate rule is selected in step S3 to pack again, until all cartons are packed.
[0043] Example 3 This embodiment is a third embodiment of a flexible centralized packing method. This embodiment is similar to embodiment one or two, except that the flexible centralized packing method in this embodiment further includes step S5: Check whether the iron frame boxes 200 packed according to the second priority rule and the third priority rule have overflow. If there is overflow, it can be adjusted manually. Check whether the gross weight of the 200 iron frame boxes packed according to the first priority rule, the second priority rule, and the third priority rule exceeds the load-bearing requirements of the iron frame boxes. For those that are overweight, they can be adjusted manually.
[0044] After packing is completed, checking whether the iron frame box overflows and whether the gross weight of the iron frame box exceeds the limit can further prevent the risk of overflow and improve operational safety.
[0045] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.
[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
