The conformity determination unit 4 compares the conformity attribute value stored in the conformity determination attribute memory 3 with the attribute value of the unit data retrieved from the unit data memory 1 and determines that they are conformity when both match. . If no matching attribute value is stored in the matching determining attribute memory 3, it is unconditionally judged as matching. The conformance attribute value generation unit 2 generates the conformance attribute value of the unit data determined to be conformance by the conformity determination unit 4 and stores it in the conformity determination attribute memory 3. The specific lot formation by this device A ₁ will be mainly described below with reference to FIG.
4 will be described in order of steps S1, S2, .... The prerequisites for lot organization are as follows. (1) Perform lot organization work in a manufacturing plant that processes steel ingots into bars. (2) There are two types of raw materials, S25C material and S9CK material. Be sure to make different lots without mixing both. (3) 1 lot 500kg machine and 1 lot 10
There are two machines of 00 kg, and the processable lot sizes are 460 kg to 500 kg and 960 kg to 100, respectively.
It is in the range of 0 kg. It is necessary to have a lot that can be supplied to one of the processing machines, and the lot will be completed if the total weight of the combination of unit raw materials falls within either range. (4) The 500 kg machine and the 1000 kg machine have the same priority. Further, it is assumed that a plurality of unit data as shown in FIG. 5 are stored in the unit data memory 1 in advance, and all of the unit data are targets of lot organization. First, as shown in FIG. 14, after the initial setting (S1 to S3), the unit data No. 1
From the unit data memory 1 (that is, a in the figure is 1) (S4). Unit data No. The material of 1 is S25C,
The weight (kg) is 120 (that is, b is S25C) (S6). At the beginning, since there is no combination of preceding unit data, the matching attribute value b is stored in the matching determination attribute memory 3.
_There is no ₁ , and the conformity determination unit 4 determines that the unit data conforms unconditionally (S7). The unit data N
o. a, that is, 1 is stored in the combination memory 5 (S
9). Then, the lot completion determination unit 6 determines whether or not the combination of unit data in the combination memory 5 is completed as a lot. At this time, the unit data is No. Since there is only one, if the weight (kg) is added, the sum SUM is 120, and 460 ≦ SUM ≦ 5
00 or 960 ≦ SUM ≦ 1000 (hereinafter, referred to as lot formation condition) is not satisfied. Therefore, it is determined that the lot is not completed (S10, S11). Before checking the next combination, the compatible attribute value generation unit 2 is activated. At this stage, since there is no combination of the preceding unit data, the attribute value b of the new unit data, that is, the material S25C is generated as the compatible attribute value b ₁ (S1
2). Then, the matching attribute value b ₁ is stored in the matching determining attribute memory 3 (S13).

Next, the unit data No. Other unit data is added one by one to the combination of 1 (S14, S15), and the lot completion is checked each time. Unit data No. 2 is selected from the unit data memory 1 (that is, a is 2) (S4). The matching attribute value b _{1 in the} matching determining attribute memory 3 is S25C (S5 to S5C).
S7), the conformity determining unit 4 determines the unit data No. Two
Since it matches the attribute value b (S25C) of, it is determined to match (S8). The unit data No. That is, 2 is additionally stored in the combination memory 5 (S9). And
In the lot completion determination unit 6, the combination number of the unit data in the combination memory 5 is determined. 1 and No. It is determined whether or not 2 and 2 are completed as a lot. If the weight (kg) of these unit data is added, the sum SUM is 2
Since it is 30 and the lot formation condition is not satisfied, it is determined that the lot is not completed (S10, S11). Next, the compatible attribute value generation unit 2 is activated. The unit data No. is stored in the matching determination attribute memory 3. The attribute value b of 2 is S25C
Therefore, the compatible attribute value b _{1 of} S25C is stored (S12, S13) (after all, the value does not change). Next, the unit data No. 1 and unit data No. Other unit data is added to the combination of 2 and (S14, S15), and the lot completion is checked each time. Unit data No. 3 is selected from the unit data memory 1 (that is, a is set to 3) (S4). The matching attribute value b _{1 in the} matching determining attribute memory 3 is S25C (S5 to S7), and the unit data No. Since it is different from the attribute value b (S9CK) of No. 3, it is determined not to match (S8). Therefore, the unit data No. 3 is not stored in the combination memory 5. As a result of sequentially repeating steps S4 to S15 for all the unit data stored in the unit data memory 1 in this way, as shown in FIG.
1, 2, 4, 6, 7, 8, 9 are stored in the combination memory 5. At this time, the sum SUM of the weights of the unit data is 96
Since the value becomes 0 and the lot formation condition is satisfied, it is determined that the lot is completed (S10, S11). Then, this unit data No. Combination information (No. 1, 2, 4,
6, 7, 8, 9) are registered in the completed lot memory 7.
At the same time, those Nos. In the unit data memory 1 are stored.
It is stored that the flags corresponding to each of the above are erased and the lot has been organized (S16). Further, the matching determination attribute memory 3 and the combination memory 5 are cleared (S17 to S20).

As described above, first, the unit data No. Lot formation that selected 1 is completed. Then, lot formation is performed by selecting other unit data. That is, the steps (S4 to S20) similar to the above are executed while excluding the unit data whose flag has already been erased from the lot organization. In this example, if the execution is further continued, the remaining unit data will disappear before the lot is completed. Therefore, it is necessary to terminate the trial and replace the first unit data of the combination. What is finally obtained is the two lots shown in FIGS. 8A and 8B, both of which are registered in the completed lot memory 7. As described above, according to the first embodiment, the automatic lot formation can be performed quickly and reliably. Note that the first embodiment does not try all possible combinations of unit data, but continuously arranges unit data of the same material (except unit data in which the flag is already erased). The lot completion is checked for the combination of unit data. Combinations other than the above can be examined in the second embodiment below. That is, as shown in FIG. 2, the lot organization device A _{2 according} to the second embodiment is
A unit data memory 1, which is all the constituent elements of the lot organization A _{1 according} to the first embodiment, a matching attribute value generating unit 2, a matching determining attribute memory 3, a matching determining unit 4, a combination memory 5, and a lot completion determining unit. 6 and the completed lot memory 7, the lot completion determining unit 6 does not determine that the lot is completed until the matching determining unit 4 completes the search for all unit data newly stored in the unit data memory 1. In addition, a combination changing unit 8 (corresponding to a changing unit) that changes the combination of the unit data stored in the combination memory 5 is provided. Hereinafter, a specific lot organization by the device A ₂ will be described in order of steps S101, S102, ... While mainly referring to FIG.
In addition, as a precondition of the lot formation at this time, the following condition (5) is added to the preconditions (1) to (4) of the first embodiment. (5) Within one lot, the difference between the maximum value and the minimum value of the completed outer diameter of the bar must be within 7 mm. Further, it is assumed that a plurality of unit data as shown in FIG. 6 is stored in the unit data memory 1 in advance, and all this unit data is the object of lot organization. First, as shown in FIG. 15, after initial setting (S101 to S104), the unit data N
o. 1 is selected from the unit data memory 1 (that is, a is set to 1) (S105). Unit data No. The material of 1 is S25
C, the completed outer diameter (mm) is 50, and the weight (kg) is 120 (that is, b is S25C and d is 50). First, the procedure similar to that of the first embodiment is used to determine whether the lot is completed (S106 to S113). When it is determined that the lot is not completed, the matching attribute value generation unit 2 is activated before checking the next combination. At this stage, since there is no combination of the preceding unit data, the value b of the inner material of the attribute values b and d of the new unit data
That is, S25C is generated as the compatible attribute value b ₁ , and the minimum value d ₁ and the maximum value d ₂ of the completed outer diameter are the values d of the unit data itself, that is, 50 (S 25 C).

The contents are shown in FIG.

As a result of sequentially repeating steps S105 to S118 in this way, nine unit data Nos. 1, 2,
4, 6, 10, 14, 16, 19, and 21 are stored in the combination memory 5. At this time, the sum S of the weights of the unit data
The UM is 1210, and the lot formation condition is not satisfied, so it is determined that the lot is not completed (S112, S).
113). Next, the compatible attribute value generation unit 2 is activated. Unit data No. The material of the attribute values b and d of 21 is S25C
Since the maximum value and the minimum value of the completed outer diameter (mm) remain 55 and 48, respectively (S114), these values are stored in the matching determination attribute memory 3 (S115). The combination memory 5 and the matching determination attribute memory 3 at this time
FIG. 9D shows the stored contents of the. However, since the unit data no longer remains, the trial is temporarily stopped. Here, the following operations are performed by the combination changing unit 8. That is, the unit data No. stored last in the combination memory 5 is stored. Two

21). Still, the lot is not complete as I have already tried. Next, the unit data No. before that. 19 is also removed from the combination memory 5. Unit data No. Up to 16 are traced back to the stage stored in the combination memory 5 and the continuation is tried (S105 to S121). Unit data No. 1
The unit data No. 9 is determined to be compatible by the compatibility determining unit 4 after the removal of the unit data No. 9. 21, the unit data No. 21 is additionally stored in the combination memory 5 (S105 to S111). No. 1, 2, 4, 6,
Eight unit data of 10, 14, 16, and 21 are stored in the combination memory 5. The lot completion determination unit 6 determines whether the combination of unit data in the combination memory 5 is completed as a lot (S11).
2, S113). If the weights (kg) of the unit data are added, the sum SUM of them is 1070, which does not satisfy the lot formation condition, and thus it is determined that the lot is not completed. Next, the matching attribute value generation unit 2 is activated. Unit data No. Of the 21 attribute values b and d, the material is S25C
Since the maximum and minimum values of the completed outer diameter (mm) are 55 and 48, respectively (S114), these values are stored in the matching determination attribute memory 3 (S115). There are no more unit data left, so the trial ends again.
Here, the unit data No. stored last in the combination memory 5 is stored. 21 is removed from the combination memory 5 (S
119-S121). Still, the lot has not been completed as we have already tried. Next, the unit data N before that
o. 16 is also removed from the combination memory 5. Unit data No. 14 is traced back to the stage stored in the combination memory 5 and the continuation is tried (S105 to S121).

Similarly, as a result of proceeding the trial backwards, the four unit data Nos. Lots of 1, 2, 6, 17 were obtained. Weight of unit data (k
g), the sum SUM of them is 460,
The judgment conditions of the lot completion judgment unit are satisfied. The contents stored in the combination memory 5 and the matching determination attribute memory 3 at this time are shown in FIG. However, since the matching attribute value generating unit 2 is not activated, the contents stored in the matching determination attribute memory 3 are unit data No. It is up to 6. Unit data No. 1
For the attribute values b and d of No. 7, the material is S25C, and the maximum and minimum values of the completed outer diameter (mm) are 55 and 48, respectively. 17 outer diameter (mm) value 4
5 indicates that the lot is completed when 50-45 = 5 <7 is determined by the conformity determination unit 4 to be compatible. In addition,
As shown in Fig. 9 (d), the completed outer diameter (m
m), the maximum value d ₂ and the minimum value d ₁ are 55 and 48, respectively. It should be noted that 17 eventually matched. Unit data No. The combination information of Nos. 1, 2, 6 and 17 is registered in the completed lot memory 7, and at the same time, those No.s in the unit data memory 1 are registered. The flags corresponding to each of the above are erased, and it is stored that the lot has been organized (S122). After that, the trial was continued in the same manner while excluding the unit data in which the flag was erased (S105 to S126), and four sets of lots were obtained. The contents of the obtained lots are shown in FIGS. As described above, according to the second embodiment, the lot organization can be performed by all the effective combinations of the unit data. By the way, when there are two types of processing machines at the time of lot organization in an actual manufacturing factory, the priority order of the processing machines to be used may be given considering the yield and the like. Therefore, this will be dealt with in the case where the priorities of the processing machines are given in the third embodiment described below. As shown in FIG. 3, the lot organization device A _{3 according to the third} embodiment is a unit data memory 1 of the constituent elements of the lot organization devices A ₁ and A ₂ according to the _first and _second embodiments. In addition to the conformity attribute value generation unit 2, the conformity determination attribute memory 3, the conformity determination unit 4, the lot completion determination unit 6, and the completed lot memory 7, the conformity determination is performed for all unit data newly stored in the unit data memory 1. A unit data secondary memory 9 (corresponding to a third storage unit) that stores unit data that has been searched by the unit 4 and that has been determined to be compatible, and a second compatibility determination unit 10 that searches the unit data secondary memory 9 And, the unit data number is sequentially decreased until the combination of an appropriate number of unit data searched by the second conformity determination unit 10 for the unit data stored in the unit data secondary memory 9 matches a predetermined lot organization condition. Appropriate number Second, the combination information of the unit data is taken out when the combination of the unit data matches the predetermined lot organization condition.
The lot completion determination unit 11 (corresponding to extraction means) and the second combination memory 12 that stores combination information of unit data before being taken out by the lot completion determination unit 11 are provided.

In this device A ₃ , the unit data secondary memory 9
Is used to form lots in the process in which lots of unit data in the unit data secondary memory 9 are completed as many as possible. Therefore, a two-stage lot composition is adopted. Then, the lot completion determination unit 6 used for the first stage composition unconditionally determines that the lot is incomplete. In addition, the second conformity determination unit 10 used for the second stage composition also determines that the conformance is unconditional. Hereinafter, with reference mainly to FIGS. 16 and 17 specific lots organized by the device A _3, step S201, S2
02, ... will be described in this order. As a precondition for the lot formation at this time, the following condition (6) is added to the preconditions (1) to (3) and (5) of the first and second embodiments. (6) 10 lots per lot with higher yield than 500 kg machine
The 00kg machine has a higher priority. Therefore, lot formation should be performed in the process of completing lots of unit data as much as possible first. Further, in the unit data memory 1, similarly to the second embodiment,
It is assumed that a plurality of unit data as shown in FIG. 6 are stored, and all of the unit data are targets of lot organization.
First, as shown in FIG. 16, initial setting (S201 to S20
4) After that, from the unit data in the unit data memory 1, the No. of the unit data to be the head is displayed. Are sequentially selected from 1 (that is, a is 1, 2, ...) (S205). At this time, the unit data No. whose flag is not erased If the flag is already erased, select the next No.
Are searched in order to find unit data whose flag is not erased (S206). If not found, the lot formation ends. If found, the unit data No. First, the execution of the first stage composition is started. First, the No. in the unit data memory 1 is set. The flag of 1 is not erased, so its material, finished outer diameter (m
m) is checked (S207). Unit data No. The material of No. 1 is S25C and the completed outer diameter (mm) is 50 (that is, b is S25C and d is 50) (if the unit data No.
If the flag of 1 is erased, the unit data No.
1 is skipped and the next unit data No. The same two items should be examined. The same applies below). And the first and second
It is determined whether the lot is completed or not by the same procedure as in the embodiment (S208 to S212). However, the first
In the staged formation, the conformity determination unit 4 unconditionally determines that the lot is not completed. Before checking the next combination, the compatible attribute value generation unit 2 is activated. At this stage, since there is no combination of the preceding unit data, the material value b, that is, S25C, among the attribute values b and d of the new unit data, is generated as the compatible attribute value b ₁ . As the minimum value d ₁ and the maximum value d ₂ of the finished outer diameter value d or 50 of the unit data itself is generated (S213). Then, these matching attribute values b ₁ , d ₁ and d ₂ are stored in the matching determining attribute memory 3 (S214). Unit data 2 at this time
The stored contents of the next memory 9 and the matching determination attribute memory 3 are shown in FIG.

Next, the unit data No. Other unit data is added one by one to the combination consisting of 1 (S215 to S217), and it is determined that the lot is not completed each time. In this way, step S205
As a result of sequentially repeating S217, as shown in FIG. 1, 2, 4, 6, 10, 1
4, 16, 19, and 21 are stored in the unit data secondary memory 9 (S211). The lot completion determination unit 6 determines whether or not the combination of the unit data in the unit data secondary memory 9 is completed as a lot, and unconditionally determines "not completed" (S212). Next, the compatible attribute value generation unit 2 is activated. Unit data No. Of the 21 attribute values b and d, the material is S25C and the completed outer diameter (mm)
Since the maximum value and the minimum value of are respectively 55 and 48 (S213), these values are the matching determination attribute memory 3
(S214). However, the unit data no longer remains in the unit data memory 1 (S215 to S2).
16). In the third embodiment, the second stage composition is activated here. In the second stage organization, the unit data secondary memory 9 is already available.
M unit data (No. 1, in this example,
Lot composition is performed by selecting M'unit data from among 9, 4, 21, 6, 9, 19, and 21). Lot formation is performed in the process described below to complete the process. Also in the second stage lot organization, initial setting is first performed (S218 to S222). Among them, the number M of unit data in the unit data secondary memory 9 is checked. M = 9
Is. Next, one unit data is selected from the unit data secondary memory 9 (S223), the second conformity determination unit 10 unconditionally determines conformity (S224), and stores it in the second combination memory 12 (S225). ). Then, the second lot completion determination unit 11 checks whether the combination of the nine unit data stored in the second combination memory 12 is completed as a lot (corresponding to the case of M ′ = M) (S226 to S234). ). If not completed, then eight unit data are selected and it is checked whether or not all combinations thereof are completed as a lot (corresponding to the case of M '= M-1). If it is not completed yet, then seven unit data are selected and it is checked whether or not all combinations of them are completed as a lot (corresponding to the case of M '= M-2). In the same way, the number is sequentially reduced, and finally one unit data is selected to check whether or not the combination thereof is completed as a lot (M '= M-n, n = 1, 2, ... , M-1
Equivalent to.

Here, the required unit data number m1 in FIG.
Is the number of unit data to be replenished to make the number of combinations of unit data M ', and the remaining number m2 of unit data is the unit data No. of the combination candidate. Order (ie 1,2,4,6,10,14,16,19,21
It is the number of the following unit data that remains based on the order. As a typical case, a case will be described below in which M ′ = 7 unit data are selected and it is checked whether or not all combinations thereof are completed as a lot. For example, the contents stored in the second combination memory 12 are as shown in FIG. In this case, the unit data No. When the combinations of 1, 2, 6, 10, and 14 become more, two more unit data are required, while three candidate unit data (No. 16, 19, 21)
Since it remains, it is possible to replenish the unit data to make 7 pieces. Therefore, the unit data No. 16
Is additionally stored in the second combination memory 12. Similarly, if the replenishment is continued thereafter, the contents stored in the second combination memory 12 will be as shown in FIG. At this time, the required unit data number m1 becomes 0 (S229), which means that seven unit data have been selected, and the second lot completion determination unit 11 works for the first time here. That is, if the weights (kg) of all the unit data belonging to the second combination memory 12 are also added by also referring to the values of the weight (kg) in the unit data memory 1, the sum SUM becomes 920, and the lot organization condition Is not satisfied, it is determined that the lot is not completed (S23).
3, S234). Next, the last unit data No. in the second combination memory 12 is stored. Since the succeeding candidate is still present even after removing 19 (it is clear from the fact that the remaining unit data number m2 is 1) (S237), the unit data No. 19 is removed (S238, S232), and instead the subsequent unit data No. 21 is stored (S223 to S228). Since the required unit data number m1 becomes 0 (S229), it means that 7 unit data have been selected, and the second lot completion determination unit 11 operates. However, it is determined that the lot is not completed because the lot organization condition is not satisfied (S233, S
234). Next, the last unit data No. in the second combination memory 12 is stored. If 21 is removed, the subsequent candidate m2
(There is no remaining unit data number m2 is 0) (S237). 16
Is removed, and the subsequent unit data No. is replaced. 19 is stored (S235 to S238, S232, S223 to S22.
5). Since the number of required unit data m1 is 1, the subsequent unit data No. 21 is stored. Since the required unit data number m1 becomes 0, seven unit data have been selected, and the second lot completion determination unit 11 operates. However,
Since the lot organization condition is not satisfied, it is determined that the lot is not completed (S233, S234).

Next, the last unit data No. in the second combination memory 12 is stored. If No. 21 is removed, there are no subsequent candidates (it can be known from the remaining unit data number m2 being 0) (S273), so the previous data No. Try to remove 19. However, the required number of unit data m1 = 1,
Since the number of remaining unit data m2 = 1, No. If 19 is removed, (the required unit data number m1> the remaining unit data number m
It becomes 2), and it is understood that even if the candidate unit data is supplemented thereafter, 7 combinations cannot be made (S237). Therefore, (required unit data count m1 <remaining unit data count m
It is necessary to go back to the unit data described in 2). N of unit data in the second combination memory 12
o. No. 14 is (required unit data number m1 <remaining unit data number m2). No. 14 of the succeeding unit data is replaced with No. 14. The trial is continued from the place where 16 is stored (S235 to S238, S232, S223).
~ S225). If the trial is continued in this way, the contents of the second combination memory 12 become as shown in FIG. 12C, and the required unit data number m1 becomes 0 (S229), so that seven unit data have been selected. Then, the second lot completion determination unit 11 operates. That is, if the weight (kg) of all the unit data belonging to the second combination memory 12 is also referred to by referring to the value of the weight (kg) in the unit data memory 1, the sum SUM becomes 960. Therefore, since the lot organization condition is satisfied, it is determined that the lot is completed (S23).
3, S234). In this way, 7 unit data N
o. Lots consisting of 1, 4, 6, 10, 14, 16, 19 were obtained. Since lots were organized in the process of completing lots of unit data as much as possible first, the data in the unit data memory 1 is exactly the same as that in the second embodiment, but the second embodiment is performed. Larger lots were obtained than those obtained in the examples. Combination No. 1,
4, 6, 10, 14, 16, 19 are completed lot memories 7
Be registered with. At the same time, those Nos. In the unit data memory 1 are stored. Flags corresponding to each of the above are erased, and it is stored that the lot is organized (S2).
42). Then, the second stage formation is completed. As a result of checking whether all combinations of the 7 unit data are completed as a lot, if they are not completed,
Next, six unit data are selected (S239 to S2
41) It is checked whether or not all combinations thereof are completed as a lot (S222 to S238). In the same way, the number of units will be reduced in the same way, and finally one unit data will be selected to check whether or not those combinations are completed as a lot. If the lot is still not completed, the second stage formation is completed without completion.

After that, if the trial was continued, another three sets of lots were obtained. The obtained lot is shown in FIG.
It shows in (d). As described above, according to the third embodiment, the lot organization can be performed so that the maximum number of unit data is included. As a result, (1) Lot formation, which was conventionally done manually, is automatically performed, and the formation time is shortened. As a result, about 1000 pieces of order data are organized into lots in 3 minutes. This is much faster than manual work. (2) Since it is an automatic formation, it is an objective lot formation. (3) Since many combinations of unit data, which cannot be exhausted by conventional manual work, can be examined, the lot organization rate increases and the delivery rate achievement rate improves. (4) In particular, since the trials of useless combinations are omitted by the actions of the attribute memory 3 for matching determination, the matching determining unit 4, and the matching attribute value generating unit 2, the time for automatic organization increases by checking all combinations. Can be prevented. Although the combination memory 5 is clearly separated from the unit data memory 1 in both the first and second embodiments, the combination memory 5 and the unit data memory 1 may be integrated in actual use. For example, FIG. 4 shows a case where the combination memory 5 and the unit data memory 1 are integrated in the first embodiment. The contents stored in the unit data memory 1 are as shown in FIG. 7 at the stage in which the formation of the second lot by the lot forming apparatus A ₁ ′ as shown in FIG. 4 is being tried.
The combination No. of FIG. Unit data N is 2
o. If only these are combined, the sum SUM of the weight (kg) is 480, which satisfies the lot formation condition, so that it is determined that the lot is completed. In this example, it seems that the combination memory 5 is not necessary, because the unit data memory 1 holds the information capable of identifying the combination of the unit data. In the third embodiment, when shifting from the first stage lot formation to the second stage lot formation, the process immediately shifts to the second stage. However, in actual use, first, there are several orders for selecting unit data. If the number of unit data stored in the unit data secondary memory 9 is the largest, the number of unit data stored in the unit data secondary memory 9 is changed to the second stage lot composition. It is even more effective in completing the lot in advance.
