Classifying the materials required by the steel bars according to types, specifications, single lengths and the number of the materials required by the steel bars to form z, wherein each row z comprises (a2, b2, c2 and d2) so as to form a required material table; wherein a2 is the type of the required material, b2 is the specification of the required material, c2 is the single length of the required material, and d2 is the number of the required material.

In some preferred embodiments, the forming of the demand planning array corresponding to each row x by using z includes the following steps, and in this embodiment, data in the excess stock table, where x is 12, that is, data in the 12 th row a is HRB400, b is 16, c is 5487, and d is 30, is taken as an example, and specifically, the following steps are taken:

if a is a2 and b is b2, then x corresponds to z and z is accessed_iWherein z is_iAll data in the chart that satisfy a ═ a2, and b ═ b2 are needed; i is the row number of all data satisfying the condition;

all z are_iAccording to d2_iC2_iArranging in descending order to form a needed planning group corresponding to the x, wherein the needed planning group is M ═ c2_i:d2_iWhere d2_iIs corresponding to z_iThe number of required materials in (1), c2_iIs corresponding to z_iMedium length of material. Since the data of one row of the excess material inventory table corresponds to a plurality of rows of data in the demand table, i is used for distinguishing the corresponding rows of data in the demand table.

The specific operation in this embodiment is as follows:

according to the excess stock table, x is 12, namely data of 12 th row of data a is HRB400, b is 16, c is 5487, and d is 30, three rows of data meeting the condition are found in the required planning table, wherein the three rows of data are as follows: 3(HRB400, 16, 322, 33), 4(HRB400, 16, 6572, 19) and 5(HRB400, 16, 1547, 30);

33 pieces of 322, 19 pieces of 6572 and 30 pieces of 1547 are arranged in descending order to form a required parameter set M, namely [6572,.. eradiation, 6572, 1547, eradiation, 1547, 322, eradiation and 322] for utilizing the excess material from long to short for blanking and facilitating the next step.

In this embodiment, the remainder c 5487 is described by using a notation group of [6572,. solstice, 6572, 1547,. solstice, 1547, 322,. solstice, 322 ]:

in this example, c 5487, M₁6572; if the judgment is made in step S102 and 6572 > 5487, the process proceeds to step S103.

In step S103, one 6572 is deleted from M to obtain M_S，M_SThere are 18 6572, 30 1547, 33 322 left; the process proceeds to step S104.

In step S104, M is taken_S1，M_S1In this case 6572, 6572 > 5487, M_S1Pointing to the next element, the next element is 6572.

In step S105, step S104 is repeated until the current element M_s11547 when it is the first 1547<5487 and updating c, wherein c is 5487 and 1547 is 3940, storing 1547 in t and t is [1547 ]]And from M_SDelete one of 1547, update M_SAfter update M_S18 6572, 29 1547, 33 322;

step S104 is repeated, and c is 3940, where M is updated_SGet M_S1，M_S11547, 1547<3940, updating c, when c is 3940-]And from M_SDelete one of 1547, update M_SAfter update M_S18 6572, 28 1547, 33 322;

step S104 is repeated, and c is 2393, where M is updated_SGet M_S1，M_S11547, 1547<2393 and c is updated, wherein c is 2393 and 1547 is 846, and t is 1547 stored in t and t is [1547, 1547]And from M_SDelete one of 1547, update M_SAfter update M_S18 6572, 27 1547, 33 322;

step S104 is repeated, and c is 846, where M is updated_SGet M_S1，M_S11547, 1547>846, then M_s1Point to M_s1547 of the next element;

step S104 is repeated until the current element M is reached, and c is 846_S1Is the first 322, 322<846, update c, when c is 846-]And from M_SDelete one 322, update M_SAfter update M_S18 6572, 27 1547, 32 322;

step S104 is repeated, where c is 524 and M is_S1Is 322, 322<524, updating c, when c is 524-]And from M_SDeletion inOne 322, update M_SAfter update M_S18 6572, 27 1547, 31 322;

step S104 is repeated, and c is 202, at which time M is updated_SGet M_S1，M_S1Is 322, 322>202, then M_s1Point to M_sThe next element 322;

continuing to repeat the step S104 until M is traversed_SIf the residual length of the residue cannot be cut to any element in the required design group, the blanking plan t of the residue is finally obtained [1547, 1547, 1547, 322 ═ 1547]The remaining length is 202, and the update requirement is given by the program array M ═ M_S＝{6572:18,1547:27,322:31}。

Then, the next excess material is blanked according to the above-mentioned mode, i.e. the steps S101 to S105 are repeated until the element in the required plan array M is empty, and finally the blanking plan array T ═ T [ T ] of the row of data is obtained₀,t₁,...,t_k-1]。

In some preferred implementations, the targeted objects of the remainders can be rods, in particular steel bars and pipes.

In summary, the blanking method has the following advantages:

(1) classify the clout, form multirow data, be convenient for manage the clout to during the unloading, the data of the clout that will unload with need with drawing the table contrast, can know the clout fast and can cut into which kind of materials that need, make the clout maximize satisfy and need the requirement.

(2) When each row of excess materials are blanked, each excess material in each row of excess materials has a corresponding blanking cutting plan, and the number of the required materials which can be cut into the excess materials and the residual quantity after cutting can be obtained through the blanking cutting plan of each excess material, so that powerful guidance is provided for field cutting of workers.

(3) And the excess stock table and the required planning table are subjected to data updating, so that after each excess stock utilization and blanking, the data are clearly and clearly recorded, and the excess stock formed after each blanking is stored into the excess stock table as new data, so that the circulation blanking of the excess stock is realized, and the resources are fully utilized.

It should be understood that the blanking method for the excess material can also perform blanking for the raw material; the clout compares, the raw materials of same type, specification, single long is general all the same to the single long of raw materials is general all to be greater than the material that needs to use, and the radical of raw materials is general sufficient in addition, leads to when utilizing the raw materials unloading, and the unloading situation is comparatively simple, consequently is to the unloading of raw materials to the simple situation application of clout unloading, specifically is:

classifying and recording the raw materials to form a raw material inventory table;

acquiring plan data of materials to be used, and carrying out classification recording to form a planning table of the materials to be used;

according to the raw material inventory table, finding out corresponding data in the required utilization planning table, and forming a required utilization planning array;

planning blanking by using a raw material inventory table according to the required utilization planning array to obtain a blanking planning array of raw materials;

and (5) blanking the raw materials according to the blanking plan array.

The blanking method in the application can carry out blanking on the raw materials after the blanking of the excess materials in the excess material warehouse is finished, can carry out blanking on the excess materials, can carry out blanking on the raw materials in the same way, increases the application range of the method, carries out blanking according to the excess materials in a way of carrying out blanking on each row of data and each column of data, also fully utilizes and records the raw materials, and avoids material waste.
