Description

Technical Field

The application relates to the technical field of paper product production, in particular to an online customized production platform and method for special-shaped corrugated paper.

Background

The paper product processing industry is one of the important industries in China, both corrugated boards for packaging boxes and paper towels serving as sanitary articles are indispensable daily articles in daily life, and most of packages of products, goods and other articles are wrapped and contained by the packaging boxes formed by paper products. Due to the special shape of some commodities and goods and the reason that the commodities and the goods are convenient to carry by hand, hold by hand and have strong protection performance, the special-shaped corrugated paper is adopted to package the commodities and the goods.

When a user places a bill to purchase special-shaped corrugated paper, basic information of the corrugated paper needs to be determined according to the requirement of the user, for example, the shape, the size, the number, the additional performance and the like of the corrugated paper box are used as order information, the order information is sent to a corrugated paper manufacturer, and the corrugated paper board capable of being integrally packaged through assembling, folding and the like is produced by the manufacturer according to the order information provided by the user. Due to the fact that the application range of the special-shaped corrugated paper is small, the order is usually characterized by small batch and multiple types. The existing production mode of corrugated paper boards is mainly to produce each order as an independent production batch, but the number of produced pieces in the order of the special-shaped corrugated paper package is small, but the production types are more, and the corrugated paper products are usually obtained by assembling a plurality of paper board pieces, so that only the paper boards in the self batch can participate in typesetting in the production process by the production mode, the limitation of typesetting is large, and the typesetting mode of saving more raw material paper boards is difficult to obtain through the diversity of the shapes of the paper boards.

At present, a mode of performing mixed typesetting on cardboard pieces in orders of a plurality of different batches also exists, but the mode also needs to consider parameters of other items in order information, such as requirements on corrugated paper corrugation, layer number and strengthening function, and especially needs to consider the problem of how to perform typesetting production under the condition that information in the order information is missing, such as that a user orders 50 corrugated papers with certain types of shapes and specified corrugated paper size, but the requirements on the corrugated paper corrugation, the layer number and the strengthening function adopted by a carton are not explicitly made. Therefore, how to perform mixed typesetting of multiple orders under the condition of ensuring that the order requirements are met and how to produce the orders with information loss so as to ensure that the order requirements are met and optimize the typesetting layout to save the raw material paperboard are problems to be solved urgently at present.

Detailed Description

In order to make the implementation objects, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the drawings in the embodiments of the present application.

An embodiment of the online customized production platform for profiled corrugated paper disclosed in the present application is described in detail below with reference to fig. 1 to 11. As shown in fig. 1, the platform disclosed in this embodiment mainly includes: the system comprises an order information acquisition module, an order dividing module, an order combining module, a paperboard typesetting module and a paperboard cutting device.

The order information acquisition module is used for acquiring specification item parameters and required quantity of the special-shaped corrugated case from the user order.

The user can order and customize and purchase the required different-type corrugated case through the official website of the manufacturer or the mobile phone APP, and the user needs to provide the parameter information of the required corrugated case when ordering, including the parameters of each specification item and the required number of the corrugated cases. The specification items mainly comprise the structure type, the edge type, the layer number, the size, the strengthening function and the like of the carton. The carton structure type is the packaging structure and the packaging appearance of the different-style corrugated carton, and the carton structure type is equivalent to the carton style; the flute shape of the single-layer paperboard comprises A, B, C, E and other types, and the multi-layer paperboard comprises AB, AC, AE, CB, BB and other types; the number of layers comprises a single layer, a double layer, a three layer, a five layer, a seven layer and the like; the size refers to the information of the carton on the length, width and height dimensions, and can be expressed by micro, small, medium, large and super large sizes, and different size models represent the carton with a specific size; the reinforcing function refers to a specific function proposed for the carton for a specific purpose of the carton, and includes freshness preservation (which can be realized by coating a preservative film), heat preservation (which can be realized by coating a heat insulating coating), insect prevention (which can be realized by coating an insect-proof paint), skid prevention (which can be realized by coating a skid-proof coating), and the like.

The order dividing module is used for determining the order with all the parameters of the specific specification items determined, and classifying the order according to the parameters of the specific specification items to obtain an initial order class.

Among the various specification items contained in the order information, part of the specification items belong to the specification items which have restriction and limitation on the selection of the raw material paperboard in the production and cutting process, such as the flute shape, the layer number and the strengthening function, all three specification items need to adopt the raw material paperboard with corresponding parameters for production and cutting to obtain the carton meeting the specification item requirements, for example, a single-layer anti-slip carton of the A flute shape is needed, the single-layer anti-slip carton of the A flute shape can be finally obtained only by adopting the raw material paperboard of the A flute shape, the single-layer anti-slip carton of the A flute shape and the anti-slip coating for cutting, and the specification items which have restriction and limitation on the selection of the raw material paperboard are specific specification items. The format items for the carton structure type and size do not depend on the raw paperboard but on the production cut and therefore do not belong to a particular format item.

The following describes the order type determination process by taking table 1 as an example, wherein 9 orders submitted by users are listed in table 1, the requirements of the users for the cartons are given, and the enhanced function specification items are omitted from the table.

TABLE 1 user order type determination Table

In the user order in table 1, the order information may have parameter requirements for all specification items, or may have parameter requirements for only some specification items, where all specification items having specific parameter requirements are called order orders of the same rank, for example, five orders with

order numbers

1, 2, 4, 7, and 8, which are in turn called order orders of the

same rank

1, 2, 3, 4, and 5; some of the specific specification items that are not required to be explicitly specified are called missing orders, such as four orders with

order numbers

3, 5, 6, and 9, which are respectively missing layer number, edge type, and layer number plus edge type, and are sequentially called

missing orders

1, 2, 3, and 4.

After the order of the orderlies is determined, because the order of the orderlies belongs to the order with the most complete production information, the order of the orderlies is taken as a classification standard, the production batches are firstly divided according to the order of the orderlies, the dividing process of the order of the orderlies is described by taking the parameter requirements of specific specification items in the orders of the users as the basis in the dividing process, and the table 2 is taken as an example.

TABLE 2 user order divide by item Table

In the user orders in table 2, by comparing the specific specification item parameters of five simultaneous orders with

original order numbers

1, 2, 4, 7 and 8, it can be seen that the requirements of the

simultaneous orders

1 and 3 on the specific specification item parameters (flute shape and layer number) are the same, and both are B-type single-layer cartons, so the raw material paperboard used in cutting can be the paperboard with the same performance, and the two orders can be divided into the same batch and simultaneously cut for production, so that the

original order numbers

1 and 4 are divided into the same order, and the initial order class 1 is obtained. The parameters of the specific specification items of the other order orders with the original order

serial numbers

2, 7 and 8 are not completely the same between every two orders, so in order to meet the requirements of users, the raw paperboard used in cutting can only adopt different paperboards, and therefore the orders cannot be divided into the same batch for cutting but need to be respectively cut, so that the order with the original order

serial numbers

2, 7 and 8 are respectively divided into a single order, and finally five order orders are divided into four

initial order classes

1, 2, 3 and 4.

The order combining module is used for determining an item-missing order which comprises part of the specified specification item parameters and is not determined, and combining the item-missing order with an initial order class meeting the specified specification item parameters of the item-missing order to obtain a production order set.

The meaning of the missing order and the determination method thereof are described above, and in order to reasonably utilize the raw cardboard, the initial order classes of the

defective orders

1, 2, 3, 4 meeting the parameter requirements of the specific specification items are determined from the initial order classes, then the orders are combined, and finally, the production order sets are obtained, each production order set is a separate production batch, contains one or more different user orders, and uses different types of raw cardboard.

And the paperboard piece typesetting module is used for typesetting the paperboard pieces based on the production order set. And the paperboard piece cutting device is used for cutting the paperboard piece based on the typesetting result to obtain the special-shaped corrugated paper product.

Each production order set comprises one or more user orders, each user order is assigned to produce one carton structure type, a carton finished product of each structure type is formed by splicing, bonding and binding paperboard pieces with different sizes, shapes and numbers, therefore, each production order set comprises a plurality of different paperboard pieces to be cut, the paperboard pieces are obtained by cutting a raw paperboard with larger block size by a paperboard piece cutting device according to program setting, the typesetting of the paperboard pieces determines how the paperboard piece cutting device cuts, all the paperboard pieces contained in the production order set are typeset and arranged, then the paperboard pieces are cut according to the typesetting result to obtain an individual paperboard piece, and finally the special-shaped corrugated carton is obtained.

Compared with the mode of carrying out independent typesetting and cutting production aiming at each single user order, the mode of combining the orders and then typesetting can enable the paperboard pieces with different shapes and sizes contained in the orders to participate in the typesetting process, the types of the paperboard pieces which can be used for typesetting are increased, the mode of typesetting results caused by too few types can be prevented from being fixed due to the proper increase of the types, and the possibility of lower utilization rate of the raw paperboard caused by too few types in the typesetting results is reduced.

For example, the order a for one-in-one requires 160 flat cartons, which are formed by folding a generally cross-shaped cardboard, so that the order a only includes cardboard, namely cardboard a1, which is involved in layout, and when the order a is individually laid out and cut, the layout mode with the highest utilization rate is the layout schematic shown in fig. 2, 8 cardboard pieces a1 are arranged on one raw cardboard in fig. 2, which are respectively identified by serial numbers 1 to 8, and a total of 20 raw cardboard pieces are required to meet the requirement of 160 flat cartons, and it can be seen from the figure that a large area of vacant positions can be utilized.

If an absent order B exists, the order B requests 360 closed cartons, the carton is formed by closing a box body and a box cover, and the box body and the box cover are formed by folding a single piece of paperboard, so the order B includes two pieces of paperboard B1 and B2 participating in typesetting, and the production platform provided by the embodiment judges that the order B can be merged with an existing order a (belonging to a certain initial order class) as an absent order, and then the paperboard pieces a1, B1 and B2 are mixed and typeset, so that the mixed typesetting schematic diagrams shown in fig. 3 to 5 are obtained. Wherein, fig. 3 is a mixed layout P1, 8 paper boards a1 (serial numbers 1 to 8) and 9 paper boards B2 (serial numbers 9 to 17) are arranged, 20P 1 sheets need to be produced to obtain 160 paper boards a1 to meet the requirement of order a, and simultaneously, 180 paper boards B2 are also produced by 20P 1 sheets, which improves the utilization rate of the 20 paper boards. Fig. 4 is a layout P2, in which 18 cardboard pieces B1 (nos. 1 to 18) are arranged, and a total of 20 raw cardboard pieces are required to satisfy the number requirement of 360. Fig. 5 is a layout P3, in which 39 cardboard pieces B2 (nos. 1 to 39) are arranged, and 5 raw cardboard pieces are required to meet the requirement of the remaining 180 pieces.

It will be appreciated that the combined orders a and B require 20+20+5=45 sheets of raw paperboard, whereas the individual cut production requires 20+20+ (360/39) =50 sheets, with 360/39 requiring rounding-up. Therefore, the classification and combination of the order with the same item and the order with the missing item can save the use amount of the raw material paperboard and reduce the production cost.

It should be noted that, the order dividing module, the order combining module, and the like may be implemented based on the results of the trial combination and the pre-layout when the order dividing and the order combining are performed (as in the embodiment described below), that is, the simulated layout is already performed before the layout is performed by the cardboard component layout module, so that the cardboard component layout module may directly perform the layout by using the pre-layout scheme according to which the dividing and the combining are actually performed in order to maintain the results of the trial combination and the pre-layout without damaging the basis of the dividing and the combining.

In the embodiment, the completeness of the user order information is analyzed, the orders with high completeness and low completeness are respectively extracted, on the basis of the complete orders with high completeness and a plurality of production constraint conditions, the batch division is performed on the aligned orders, then the missing orders with low completeness and a plurality of production constraint conditions are merged with the result of the batch division of the complete orders, the batch division of the missing orders is completed, the batch division results of all orders are obtained, then the typesetting and cutting production is performed according to the batch, the multi-order merging, typesetting and cutting production is realized on the premise of meeting the order requirements, the type number of layout is reduced, the variety of the types of the plate pieces which can be discharged when the same layout is typeset is increased, the utilization rate of the raw material paperboard when the paperboard pieces are cut is improved, and the paperboard resources are saved.

In one embodiment, the platform further comprises an order merge determination module. The order merging judgment module is used for pre-typesetting a plurality of order orders to be divided into the same initial order class and calculating the utilization rate of the raw material paperboard before dividing the order orders, and when the utilization rate of the raw material paperboard of any order is not lower than the utilization rate standard threshold, the corresponding order which is not lower than the utilization rate standard threshold is independently used as a production order set.

One of the main technical effects of the present application is to improve the utilization rate of the raw material paperboard during production, so before dividing the order, it is necessary to determine whether the combination of the order is favorable for improving the utilization rate of the raw material paperboard. The merging necessity judgment process for each of the orderliness orders is shown below by taking table 3 as an example, wherein the number column and the size column are omitted because the merging necessity judgment and the subsequent order merging process do not relate to the number and the size.

TABLE 3 JUNCTION CONSUMPTION JURY LIQUIDS AND JUNCTION RESULTS TABLE FOR ORDER WITH QUILT-ORDER AND DEFECT ORDER

Before the order dividing module divides the order form of the table 1 to obtain an initial order form class, a plurality of order forms to be merged into the same initial order form class are extracted, for example, two order forms of the order form 1 and the order form 3 in the table 1, the two order forms are merged directly in the table 2 because the ridge type and the layer number are the same, in the embodiment, the two order forms are pre-typesetted firstly, the pre-typesetting mode is the same as the formal typesetting mode, and the difference is that the pre-typesetting mode can be abandoned and cannot be formal typesetting, and only is one pre-typesetting mode. The utilization rates of the raw material paperboards after pre-typesetting are calculated to be 98% and 88%, respectively, and the utilization rates are compared with a utilization rate standard threshold (95%), and the utilization rate of the raw material paperboard of the order 1 is found to be not lower than 95%, so that the order of the order 1 in the table 3 is directly used as a production order set capable of being directly produced, and the order number is 1, namely the production order set 1. The remaining full order 3 is referred to as the initial order class 1.

The reason for this is that if the full order 1 itself is taken as an individual order and meets the utilization rate reaching threshold, it indicates that the order has fully utilized the raw material paperboard, and if the order is merged with other orders, the utilization rate of the merged order does not exceed that of the full order 1 regardless of the utilization rate of the order merged with the order, and even the utilization rate of the merged order is lower than that of individual production because the typesetting scheme adopted after merging is a non-optimal scheme, and the like, so that the order 1 does not need to be merged and directly taken as a production order set, so that the subsequent missing order merging process does not need to be participated in, and the time for sorting the merged paper boards according to the carton structure type because the paper boards are mixed together is also saved. Thus, the project order 1 becomes a production order set 1 that does not participate in the division and consolidation.

It will be appreciated that the raw cardboard utilization can be calculated as: the ratio of the sum of the areas of the paperboard pieces on the raw paperboard to the total area of the raw paperboard. In addition, if the utilization rates of the raw material paperboards of the

orderlies

1 and 3 are lower than 95% after the judgment of the merging necessity of the orderlies, the

orderlies

1 and 3 are merged according to the table 2 to obtain the initial order class 1 containing the

orderlies

1 and 3. If one or more of the orderlies are separately used as a production order set after the judgment of the merging necessity of the orderlies, and a plurality of orderlies to be merged into the same initial order class remain, merging the orders to obtain the initial order class.

The order merging judgment module is also used for pre-typesetting each missing order and calculating the utilization rate of the raw material paper board before merging the missing orders, and when the utilization rate of the raw material paper board is not less than the utilization rate standard threshold, the corresponding missing order which is not less than the utilization rate standard threshold is independently used as a production order set, and the specific specification items of undetermined parameters of the production order set are determined according to the stock quantity of the raw material paper board of each specific specification item.

Before the order merging module merges the missing orders in table 1, the merging necessity determination is also performed on the missing orders, and the merging necessity determination process of each missing order is shown in table 3 as an example.

Before the order merging module merges the missing orders of table 1 to obtain a production order set, the utilization rate of the raw material paperboard of each missing order is calculated respectively, if the utilization rate of the raw material paperboard of the original missing order 1 in table 1 after pre-typesetting is 96%, the utilization rate is compared with a utilization rate standard threshold (95%), and the utilization rate is found to be higher than 95%, so that the order of the original missing order 1 is directly used as the production order set capable of being directly produced in table 3, and the order number is 2, namely the production order set 2. The reason for this is the same as the reason for pre-typesetting the alignment item order and calculating the utilization rate, and is to avoid that the overall utilization rate may be reduced if the alignment item order is merged with the initial order class subsequently.

Since the production order set 2 includes the missing order, the required specification parameters need to be completed to enable actual production. The production order set 2 lacks parameters of the layer number specification item, that is, any layer number can be selected as the layer number specification item, in the embodiment, according to the stock of the raw material paperboard with different layer numbers of the C-flute type, the single layer with the lowest cost can be selected as the layer number specification item parameter of the production order set 2, and the layer number with the highest stock can also be selected as the layer number specification item parameter of the production order set 2.

For the obtained production order sets 1 and 2, the layout arranged by the cardboard typesetting module during the pre-typesetting can be directly used as the typesetting result of the cardboard typesetting module by the order merging judgment module.

The order combining judgment module is used for carrying out pre-judgment on the combining necessity to obtain a table 3 with the order type different from that of the table 2, so that the utilization rate of the raw material paperboard is improved, and the sorting time of the paperboard pieces with different carton structures is shortened.

In one embodiment, the order consolidation module comprises: the three units are used for merging the missing order and the initial order class meeting the specific specification item parameters of the missing order to obtain a production order set.

The mergeable range determining unit is used for determining an initial order class which is consistent with all determined specific specification item parameters of the missing order from the initial order classes according to the comparison of the specification item parameters to obtain a mergeable order group of each missing order.

The precondition for merging the missing orders with the initial order classes is that the specification parameter requirements of the customer on the carton box must be met, so one of the preparation works that must be performed before merging is to determine which initial order classes each missing order can be specifically merged with (all the original order classes at this time contain the full orders), and the set of the initial order classes that are allowed to be merged is the mergeable order group of the missing orders. Table 4 below illustrates the mergeable order set for each missing order.

TABLE 4 missing order merge selection Table

In the missing order in table 4, only the layer number is required in the specific specification item of the missing order 2, that is, the layer number is required to be a single layer, and the initial order class that is also a single layer includes initial order classes 1 and 3 (although the production order set 1 is also a single layer, a production order has already been formed, and therefore does not participate in merging any more), and meanwhile, the missing order 2 does not require a ridge shape, so that the ridge shape can adopt any ridge shape, and therefore it can be determined that the mergeable order group of the missing order 2 includes the

initial order classes

1 and 3, and can be merged with any of the two classes. And the rest orders are analogized.

The single-choice order combining unit is used for determining a missing order which only comprises an initial order class in the combinable order groups, performing trial combination and pre-typesetting on the determined missing order and the corresponding initial order class, calculating a raw material paperboard consumption reduction value generated by the utilization rate change of the raw material paperboards before and after the trial combination, obtaining a raw material paperboard single cost value corresponding to the lowest cost parameter which can be selected by using an undetermined specification item of the determined missing order and a raw material paperboard single cost value corresponding to the corresponding specification item parameter of the corresponding initial order class, calculating a cost variation based on the reduction value and the two cost values, and combining the determined missing order with the corresponding initial order class when the cost variation indicates that the cost is reduced to obtain the combinable initial order class.

If the mergeable order group of a missing order only contains one initial order class, the missing order has no other merging selection and can only be merged or not merged with the initial order class, for example, the mergeable order group of the missing order 1 in table 4 only contains the initial order class 4, so before performing subsequent complex merging judgment, the missing order which can be simply determined how to merge can be merged first, the missing order 1 is merged into the initial order class 4 to obtain the merging table shown in table 5, and at this time, the initial order class 4 contains two merged orders.

TABLE 5 Single-choice missing order merge Table

It can be understood that, in order to ensure that the cost of the raw materials is not increased due to the combination, the cost variation of the raw material paperboard before and after the combination is calculated before the combination of the order combination units, the combination is performed if the cost is reduced, the combination is not performed if the cost is not reduced, the paperboard pieces of different orders need to be sorted after the combination and the typesetting production which wastes the calculation power and time, and therefore the combination is not performed unless the cost is actually reduced.

The specific cost calculation method takes the missing order 1 in table 4 as an example, the reason for cost reduction is the improvement of the utilization rate of the raw material paperboard, which is equivalent to the reduction of the consumption amount of the raw material paperboard, and the reason for cost improvement is that the number of layers is forcibly limited to the number of layers of the initial order class after combination. Therefore, the missing order 1 and the initial order class 4 need to be merged in a trial and merge manner, which is the same as the formal merge, except that the trial merge may be abandoned and cannot become the formal merge, but only as a preview. Assuming that the utilization rates of the raw material paperboards of the missing order 1 and the initial order 4 are respectively 80% and 70% before trial combination, the utilization rate of the raw material paperboard of the initial order 4 is increased to 88% due to relatively complementary and adaptive shapes after trial combination, which indicates that the consumption of the raw material paperboard is reduced, and the consumption reduction value of the raw material paperboard can be obtained by conversion according to the reduction amount of the consumption of the raw material paperboard, assuming that the missing order 1 before trial combination needs 10 sheets of raw material paperboards, the initial order 4 needs 50 sheets of raw material paperboards, and the initial order 4 after trial combination needs 56 sheets of raw material paperboards, the consumption of 4 sheets is saved, and the consumption reduction value is 4.

And acquiring the single cost of the missing order 1 when the lowest cost layer number (namely, single layer) is selected and the same as the initial order type 4 layer number (namely, 3 layers), wherein if the single cost of each single layer of raw material paperboard is calculated as 0.1 and the single cost of each 3 layers of raw material paperboard is calculated as 0.15, 10 single layer paperboards with the lowest cost are selected when the missing order 1 is independently typeset and produced, the required cost is 10 × 0.1=1, the initial order type 4 needs 50 paperboards with 3 layers per se, the required cost is 50 × 0.15=7.5, and therefore the total cost of the raw material paperboards before trial combination is 8.5; and after the original order class 4 is merged, 56 paper boards (4 saved) with 3 layers are needed, the merged cost is 56 × 0.15=8.4, and the merged cost shows that the cost is reduced and the reduction value is 0.1, so that the missing order 1 and the original order class 4 are merged to obtain the original order class 4 in the table 5, that is, the missing order with the original order serial number of 5 is produced by adopting 3 layers of paper boards, and the consumption cost of the raw material paper boards is saved. If the cost changes to be flat or rising, the missing order 1 is produced as a single production order set, since it cannot be merged with other orders, and merged orders increase the cost.

The order sorting and merging unit is used for sorting the missing orders which comprise a plurality of initial order classes in the combinable order group according to the number of the included initial order classes from small to large, and sequentially determining the initial order classes corresponding to the missing orders and merging the missing orders based on the sorting result.

Continuing to take table 5 as an example, two missing orders to be merged remain, and the two

missing orders

2 and 3 are sorted according to the number of the initial order types contained in the combinable order group, where the number of the initial order types of the missing order 2 is less than that of the missing order 3, so that the sorting results are (missing order 2 and missing order 3), and if the initial order types contained in the combinable order groups of n missing orders are the same, the sorting order of the n missing orders is adjacent, and who is first and then does not influence each other. And then combining the missing item orders 2 with small initial order type quantity contained in the combinable order groups based on the sequencing result, and then combining the missing item orders 3 with large initial order type quantity contained in the combinable order groups until all the missing item orders are combined, wherein each combined initial order type is a production order set which contains a full item order and/or a missing item order.

The following is a detailed description of how the default orders, which contain multiple initial order classes, are merged.

In one embodiment, the order sorting and merging unit comprises a current order determining subunit, a multiple-choice order number value calculating subunit and a trial ranking effect evaluating subunit.

And the current order determining subunit is used for determining a current missing order with the most front current ordering based on the ordering result, and determining a new current missing order with the most front current ordering after the current missing order is combined through the multiple-choice order numerical value calculating subunit and the trial-discharge effect evaluating subunit until the missing order does not exist.

The missing order is sequentially merged with the initial order types according to the sorting result described above, the merging order is controlled by the current order determining subunit, the current order determining subunit extracts the most front missing order 1 as the current missing order, the order is the missing order with the least number of the initial order types contained in the merged order group in all the un-merged missing orders, after the merging of the current missing order is completed by other subunits, the un-merged missing order is one less, then the current order determining subunit extracts the current most front missing order 2 according to the sorting order again, and so on until all the missing orders are merged.

The multi-choice order number value operator unit is used for trial combination and pre-typesetting of the current lack order and each initial order class in the corresponding combinable order group respectively, and calculating the cost variation between the current lack order and each corresponding initial order class and the paper board position dispersion of each pre-typeset original order.

This possibility does not exist for the missing order with multiple initial order classes that can be selected for combination, which needs to be separately judged as a production order set by the order combination judging module before, whereas for the missing order with only a single combination selection, the missing order with

multiple combinations

1 and 2 needs to take into account not only the raw material cost but also the time cost brought by the automatic sorting of the cardboard pieces of different orders, so that some values about the order need to be calculated.

The value to be calculated by the multiple-choice order value calculating subunit includes the cost variation before and after merging, and the calculation manner of the cost variation is the same as that of the single-choice order merging unit, which is not described herein again.

The value to be calculated by the multiple-choice order value calculating subunit further includes a sheet member position dispersion that reflects the degree of scattering of different order sheet members, or the degree of coupling or cohesion of different order sheet members in position.

The operator unit of the multi-choice order number value can also obtain the consumption of the raw material paperboard of the combined front lack order and the corresponding initial order type for use in subsequent calculation.

And the effect evaluation and combination subunit is used for inputting the characteristic vector formed by the cost variation, the paperboard position dispersion and the order completion time limit into a cost efficiency evaluation model, and combining the current missing order and the corresponding initial order type or using the current missing order as an independent production order set based on the evaluation result.

The cost efficiency evaluation model is a pre-established evaluation model, can analyze input vectors containing cost variation, dispersion and expected completion time to obtain an evaluation result after balancing the consumption cost of the raw material paperboard and the sorting time cost, and obtains a merging scheme of the missing order according to the evaluation result. The vector may be in the form of: [ n, (c11, d11, t1), (c12, d12, t2), …, (c1n, d1n, tn) ], where n is the number of selectable initial order classes for the out-of-order, c is the amount of cost variation, d is the cardboard position dispersion, and t1 is the earliest order completion time limit among the out-of-order and the order contained in the first initial order class. Taking the missing item order 1 in table 5 as an example, the vector is [2, (c11, d11, t1), (c12, d12, t2) ].

For missing order 1 in table 5, there are three merging scenarios: and the orders are not combined and are used as a single production order set, combined with the initial order class 1 and combined with the initial order class 3, and a corresponding combination scheme is determined as a combination scheme of the missing order 1 according to the evaluation result.

Assuming that the combination scheme corresponding to the evaluation result is to be combined with the initial order class 3, the combined initial order class 3 includes orders with original order

serial numbers

8 and 6, the original missing order 2 becomes the current missing order, the multiple-choice order number value operator unit performs trial combination and pre-typesetting on the current missing order and the

initial order classes

1, 2, 3 and 4 respectively, calculates the cost variation and the sheet position dispersion between the current missing order and the

initial order classes

1, 2, 3 and 4 respectively, the effect evaluation and combination subunit inputs the calculated data into the cost efficiency evaluation model to finally obtain the combination scheme of the original missing order 2 (combined with the initial order class 1), until all the missing orders are combined to obtain the order combination completion table shown in the table 6, and then all the initial order classes are used as the production order set, typesetting and cutting are performed in cooperation with merging the previously established production order sets 1 and 2.

Table 6 order merge completion table

It can be understood that, the production order set 1 and the production order set 2 implement pre-typesetting when the order combination judging module judges the utilization rate, the initial order set 4 implements pre-typesetting when the order combination unit judges that the orders lack items are to be combined, the initial order sets 1 and 3 implement pre-typesetting when the operator unit with multiple orders in the order sorting combination unit selects one of the orders with the number of orders lacking items, the cardboard typesetting module can be used as the typesetting scheme of the order sets and the order sets according to the pre-typesetting scheme, and the initial order set 2 is directly divided into a single initial order set from the order sets according to the flute type and the layer number, so that the cardboard typesetting module does not implement single typesetting, and then the typesetting scheme can be obtained.

In one embodiment, the step of calculating the positional dispersion of the cardboard member by the multi-order numerical operator unit includes the following steps B1 to B4.

Step B1, determining a mixed raw paperboard with more than one ordered piece of paperboard on all raw paperboard that is required to be consumed.

Taking the missing order 1 and the initial order class 1 in table 5 as an example, assuming that the missing order 1 includes 2 kinds of cardboard members, and the initial order class 1 includes 4 kinds of cardboard members, the two orders are pre-typeset after trial combination and use 70 pieces of raw cardboard, possibly, the cardboard members of the two orders are not arranged on each cardboard, and only one cardboard member of one order may be arranged on some cardboard, so that the raw cardboard on which more than one cardboard member of one order is arranged may be predetermined and referred to as mixed raw cardboard, so as to save the calculation amount in the subsequent steps.

And step B2, acquiring the central point of the circumscribed rectangle of each paperboard piece on the mixed raw material paperboard, and projecting each central point onto the long edge and the wide edge of the raw material paperboard respectively to obtain a long edge central point sequence and a wide edge central point sequence.

Because the shapes of the paper plates are mostly irregular figures, the external rectangles of the paper plates are obtained firstly, the external rectangles are rectangles which can just enclose the paper plates in the current posture, and the maximum abscissa, the maximum ordinate, the minimum abscissa and the minimum ordinate of the paper plates are used for demarcating the boundaries to obtain the rectangles. The central point of the external rectangle is the intersection point of the diagonal lines of the rectangle.

The long side of the raw material paperboard is in the length direction, namely the X-axis direction, and the wide side is in the width direction, namely the Y-axis direction. And projecting each central point to an X axis and a Y axis to obtain an X axis point sequence and a Y axis point sequence, wherein the recording sequence of the central points in the sequences is recorded in sequence from one side to the other side of the X axis or the Y axis. If a plurality of central points with the same X-axis coordinate or a plurality of central points with the same Y-axis coordinate exist, the central points are recorded in the sequence on the projection position in a flat relation. Fig. 6 is a schematic projection diagram of the cardboard of fig. 3, and fig. 6 includes cardboard a1 and cardboard B2, where a1 represents a center point by a square, B2 represents a center point by a triangle, the lower side and the left side in the figure are X-axis and Y-axis respectively, and the projections of the center points on the axes, and it can be seen that the center points at the partial projection positions are coincident, and the coincident points include both the center point of a1 and the center point of B2.

And step B3, judging the change times of the orders of the adjacent central points in each sequence according to the sequence of the central points in the sequence, and taking the change times occurring between the paper boards with the adjacent relation as effective times.

Taking the X axis in fig. 6 as an example, the order change is performed from the first position point on the left side to the second position point (which may be from right to left), where the first position point on the left side is the center point of B2, the second position point is the center point of two overlapping a1, and the order change occurs from the first position point to the second position point, but the B2 cardboard piece corresponding to the first position point has an adjacent relationship with only one a1 cardboard piece corresponding to the second position point, so the number of times is 1 × 1= 1; the third position point is the central point of two B2, the order change occurs again from the second position point to the third position point, but the two A1 paperboard corresponding to the second position point is only adjacent to one B2 paperboard corresponding to the third position point, so the times are 1 x 1+1 x 1= 2; the fourth site is the center point of a single a1, with the order of 1 x 1= 1; the fifth and sixth location points remain the center point of a single a1, and therefore are not incremented; the seventh position point is the center point of a single B2, but is not adjacent to the corresponding paperboard piece between the sixth position points, and therefore is not incremented; the eighth position is a coincidence point of a center point A1 and a center point B2, the center points B2 from the seventh position to the eighth position count no times, but the center points A1 from the seventh position to the eighth position count times, so the times are 1 × 1=1, and so on, and the corresponding order change times between every two projection positions are obtained.

And step B4, calculating the sum of the times of the two sequences as the position dispersion of the paperboard.

The change times of the orders belonging to the X axis and the Y axis are usually different, different axes reflect the dispersion degrees in different directions, and the summary of the dispersion degrees in different directions reflects the difficulty of sorting the paper plate, so the X axis and the Y axis need to be considered simultaneously, and the more times are calculated, the higher the dispersion degree is.

In an embodiment, the order combination judging module, the order combination module, and the cardboard piece typesetting module of the platform perform the pre-typesetting, and each of the steps C1 to C3 includes the following steps.

Step C1, a dischargeable region formed between the discharged sheet and the boundary of the layout on the current layout is generated.

Taking fig. 7 as an example, the left part in fig. 7 is a layout in which one discharged sheet 1 has been arranged, the current layout is the shape of the raw material cardboard, the layout boundary is the boundary of the raw material cardboard, the dischargeable region is one or more closed regions formed by dividing the raw material cardboard by a union set of all the discharged sheets, each closed region is a region not containing the discharged sheet formed by intersecting the boundary of the union set of all the discharged sheets with the raw material cardboard boundary, as shown in the right part in fig. 7, the discharged sheet 1 divides the raw material cardboard into two regions, R1 and R2.

Furthermore, before the order combining and judging module of the platform and the order combining module carry out the pre-typesetting and the paperboard piece typesetting module carries out the typesetting of the paperboard pieces, all the paperboard pieces in the order participating in the pre-typesetting or the typesetting are firstly sequenced according to the area from large to small to obtain a paperboard piece arrangement sequence, and the paperboard pieces are sequentially extracted according to the sequence in the paperboard piece arrangement sequence to carry out the pre-typesetting and the typesetting.

Taking the layout in fig. 3 and 4 as an example, if all the cardboard pieces included in the pre-typesetting or typesetting orders a and B are three types a1, B1 and B2, respectively, the order after sorting according to the sizes of the areas is: a1, B1 and B2, therefore, when typesetting or typesetting, 160A 1 in the order A in total number are typeset, then 360B 1 in the order B in total number are typeset, and finally 360B 2 in the order in total number are typeset. The reason for this is that the large paperboard pieces are arranged first, and the small paperboard pieces are filled in the blank areas formed by the large paperboard pieces, which creates conditions for saving the consumption of the raw material paperboard to the maximum.

Step C2, an inner adaptive trajectory of the sheet currently to be discharged with respect to the dischargeable region is generated.

The inner adaptation trajectory is: under the condition that the sheet to be discharged keeps in contact with the side line of the dischargeable area, after the sheet to be discharged is translated for one circle along the shape of the dischargeable area in the dischargeable area, a path through which a preset vertex of the sheet to be discharged moves is formed. As shown in fig. 8, the sheet member to be discharged is a sheet member 2 having the same shape and size as the discharged sheet member 1, the inner adaptation trajectory formed by the sheet member 2 along the dischargeable region R1 is a broken line in fig. 8, the preset vertex is a vertex from the leftmost lower corner to the leftmost lower corner of the sheet member 2, the position of the sheet member 2 in the drawing is one of the positions when the sheet member 2 is translated along the outer shape of the dischargeable region, and the inner adaptation trajectory of the sheet member 2 with respect to R2 cannot be generated because the area of the dischargeable region R2 is too small to accommodate the sheet member 2. It is understood that the region R1 and the discharged sheet member 1 are not shown in fig. 8 in order to show the inner adaptive trajectory.

It should be noted that, when the inside adaptive trajectory is generated, any side line of the sheet to be discharged cannot intersect with a side line of the dischargeable region, for example, when the sheet to be discharged is translated along the side line of the dischargeable region, a side line of the sheet to be discharged exceeds the side line of the raw material paperboard boundary in the dischargeable region, so as to cause intersection, the translation trajectory from the intersection is not taken as the inside adaptive trajectory until the sheet to be discharged continues to be translated along the side line of the dischargeable region until the sheet to be discharged no longer intersects with any side line of the dischargeable region, and then the translation trajectory thereafter is taken as the inside adaptive trajectory. The determination of intersection may be determined by determining whether an intersection occurs between the line segments. The track may be one or more unconnected closed figures, may contain both closed figures and line segments connected to them, or may be only one or more points.

And step C3, determining the optimal discharge position of the sheet to be discharged currently from the inner adaptive track.

The optimal discharge position is the position capable of saving the consumption of the raw material paperboard to the maximum, and the determination mode of the optimal discharge position mainly comprises the following two standards.

And determining the number of overlapping edges between the layout boundary and the discharged sheet when the sheet to be discharged is at each position on the inner adaptive trajectory, and selecting the position with the largest number of overlapping edges as the discharge position of the sheet to be discharged.

The overlapped side is a common overlapped side which is overlapped with any ejected sheet and the layout boundary at any position of an adaptive track including any side line of the paper sheet 2 of the current sheet to be ejected, as shown in fig. 9, when the paper sheet 2 is at a position 2', the paper sheet 2 has three overlapped sides, the first overlapped side is a side where the top side line of the paper sheet 2 is overlapped with the top of the layout boundary, the second overlapped side is a side where the left side line of the paper sheet 2 is overlapped with the left side of the layout boundary, and the third overlapped side is a side where the bottom side line of the paper sheet 2 is overlapped with the top side line of the ejected sheet 1; when the sheet member 2 is at the 2 ″ position, the sheet member 2 also has three overlapped sides, which are side lines where the adjacent three sides of the left lower portion of the sheet member 2 and the adjacent three sides of the right upper portion of the discharged sheet member 1 overlap, respectively. At this time, the number of overlapping sides of the 2' position and the 2 ″ position is the same, and the optimal discharge position cannot be determined only by the criterion, and then the criterion two is used for further selection.

And a second standard, acquiring the central point of the circumscribed rectangle of the sheet to be discharged at present when the number of the overlapped edges at the plurality of positions is the same, and taking the central point closest to the left side of the layout as the discharge position of the sheet to be discharged at present.

The center of the sheet member 2 differs between the 2 ' position and the 2 ″ position, and the center point is closer to the left side of the layout at the 2 ' position than at the 2 ″ position, so the 2 ' position is adopted as the optimum position of the sheet member 2.

As for the arrangement of the cardboard members 3, as shown in fig. 10, the broken line at the left part in the figure is an inner adaptive track formed by the cardboard members 3, and the right part is an optimal discharge position of the cardboard members 3, wherein there are actually two optimal discharge positions, and there are two optimal discharge positions after judged according to the above two criteria, and thus one is selected.

After the a1 type cardboard pieces are arranged, the B1 type cardboard pieces are arranged on the brand new raw cardboard without coexisting with the a1 and on the same cardboard, since the B1 type cardboard pieces cannot be arranged on the layout full of the a1 type cardboard pieces. Then, when arranging the B2 type cardboard pieces, the cardboard pieces can be arranged on the layout where the a1 type cardboard pieces are arranged, the remaining arrangeable region of the layout where the a1 type cardboard pieces are arranged is shown in fig. 11, there are 12 arrangeable regions R1 to R12 in total, when arranging the first B2 type cardboard piece, the B2 which finds the default posture as the lateral posture can be arranged on 8 in total of R2, R9, R3, R11, and R12, and after arranging the B2 in the lateral posture, the B2 can be rotated by a set angle, for example, by 90 degrees along the center point thereof to obtain the vertical posture, and when arranging the B2 which finds the vertical posture can be arranged on 1 in total of R4, thereby obtaining the layout where 8 a1 and 9B 2 pieces are arranged in fig. 3.
