1-3. Configuration example of the article management device 50 When the type of the substrate product 900 to be produced is switched, the type and number of articles 80 required by the substrate working machine WM0 in the production of the substrate product 900 change. Therefore, a setup change operation is performed in which the article 80 to be supplied is changed according to the type of the substrate product 900 to be produced.

In the present embodiment, a plurality of (two)

trolleys

30 and 30 that can collectively replace (replace) a plurality of feeders 122 each having a reel 121 for supplying a component 81 which is an article 80 are used for setup replacement. Work is done.

1-3-1. Classification setting unit 51
FIG. 6 shows an example of the relationship between the production plan L0, the unit production W0, and the production group G0. The production plan L0 defines the order of unit production W0 in which the production of the same type of substrate product 900 using the substrate working machine WM0 is specified. For example, in the production plan L0 shown in FIG. 6, the unit production W0 for producing the tenth type substrate product 900 from the unit production W0 for producing the first type substrate product 900 (indicated by the unit production W01 in the figure). It is shown that ten kinds of substrate products 900 up to (in the figure, the unit production W10 is shown) are produced in order.

In addition, the number of production of various board products 900, the production start date and time, the scheduled production end date and time, the delivery date, the type of equipment used, the number of equipment used, the type of article 80 required for the production of the board product 900, and the number of articles 80. Etc. are specified in the production plan L0. Further, when there are a plurality of work lines WL0 for the board capable of producing the board product 900, the work line WL0 for the board to be used is specified in the production plan L0. The production plan L0 is stored in the storage device DS0 shown in FIG.

The division setting unit 51 divides a plurality of unit production W0 included in the production plan L0 for each production group G0 (step S12 shown in FIG. 5). The production group G0 is a set of at least one unit production W0 using the article 80 supplied to the substrate working machine WM0 by the article supply medium 70 mounted on one trolley 30 at a time. The classification setting unit 51 can classify the production group G0 from various viewpoints.

For example, the classification setting unit 51 can classify the production group G0 according to the maximum number of goods supply media 70 that can be mounted on one carriage 30 at a time. Further, the classification setting unit 51 can also classify the production group G0 so that the number of goods supply media 70 mounted on one carriage 30 at one time is substantially equal for each carriage 30. Further, the division setting unit 51 can also divide the production group G0 so that the number of unit production W0 included in the production group G0, the production time, and the like are substantially equal for each production group G0.

For example, the first production group G0 shown in FIG. 6 (indicated by the production group G1 in the figure) includes the unit production W01 and the unit production W02. For the sake of brevity, the article 80 used in the unit production W01 and the unit production W02 includes a first-class part 81 (indicated by the part 81a in the figure) and a second-class part 81 (in the same figure, the part 81a). , And the two types of parts 81 shown in the part 81b). Further, the component 81a is housed in the reel 121a. The reel 121a is mounted on the feeder 122a. The component 81b is housed in the reel 121b. The reel 121b is mounted on the feeder 122b.

At this time, one carriage 30 (indicated by the carriage 30a in the figure) is equipped with a feeder 122a equipped with a reel 121a for supplying the component 81a and a feeder 121b equipped with the reel 121b for supplying the component 81b. 122b and the like are mounted at one time. When the trolley 30a is connected to the component supply device 12, the component mounting machine WM3, which is the board work machine WM0, can start the unit production W01 and the unit production W02 using the component 81a and the component 81b. The above-mentioned thing about the production group G1 can be similarly applied to the other production group G0 (in the figure, it is shown by the production group G2, the production group G3 and the production group G4).

In the present embodiment, the two carriages 30 and 30 (indicated by the carriages 30a and 30b in FIG. 6) alternately supply the article supply medium 70 to the board working machine WM0. In this embodiment, the division setting unit 51 uses a production group G0 that uses the article supply medium 70 supplied from one trolley 30, and a production group G0 that uses the article supply medium 70 supplied from the other trolley 30. The production group G0 can be divided so that and are repeated alternately.

In the example shown in FIG. 6, the production group G0 using the article supply medium 70 supplied from the carriage 30a is the production group G1 and the production group G3. The production group G0 using the article supply medium 70 supplied from the trolley 30b is the production group G2 and the production group G4. The substrate product 900 is produced in the order of the production group G1 in which the trolley 30a is involved, the production group G2 in which the trolley 30b is involved, the production group G3 in which the trolley 30a is involved, and the production group G4 in which the trolley 30b is involved.

In this way, the production group G0 (production group G1 and production group G3) in which the trolley 30a is involved and the production group G0 (production group G2 and production group G4) in which the trolley 30b is involved are alternately repeated. Therefore, when the production of the board product 900 of the production group G0 in which the dolly 30a is involved is completed, the worker detaches the dolly 30a from the parts supply device 12 and transfers the dolly 30b prepared in advance to the parts supply device 12. Can be linked. As a result, it is possible to reduce the production waiting time of the substrate product 900 of the production group G0 in which the carriage 30b is involved.

1-3-2. Allocation unit 52
As shown in FIG. 6, for example, it is assumed that parts 81a of the same type supplied from the same trolley 30a are used in different production groups G0 (production group G1 and production group G3). In this case, if the article supply medium 70 that supplies the parts 81a used in the production group G1 and the article supply medium 70 that supplies the parts 81a used in the production group G3 are different, the article supply medium 70 in the trolley 30a. Replacement work is required.

Therefore, when the articles 80 of the same type supplied from the same trolley 30 are used in different production groups G0, the allocation unit 52 trolleys so that the article supply medium 70 for supplying the articles 80 becomes the same. The article supply medium 70 is assigned to 30 (step S13 shown in FIG. 5).

In the above example, the allocation unit 52 allocates the same article supply medium 70 for supplying the component 81a to the component 81a used in the production group G1 and the production group G3. As a result, the article management device 50 can reduce the replacement work of the article supply medium 70 that supplies the component 81a. The same can be said for the parts 81c supplied from the carriage 30b. The component 81c is housed in the reel 121c. The reel 121c is mounted on the feeder 122c.

The component 81b shown in FIG. 6 is supplied from both the carriage 30a and the carriage 30b. The parts 81b supplied from the trolley 30a are used in the production group G1 and the production group G3. The parts 81b supplied from the carriage 30b are used in the production group G2 and the production group G4. As described above, it is assumed that parts 81b of the same type supplied from different carriages 30 (trolleys 30a and 30b) are used in different production groups G0. In this case, if the same article supply medium 70 that supplies the parts 81b is shared by the carriage 30a and the carriage 30b, the article supply medium 70 needs to be replaced in the carriage 30a and the carriage 30b.

Therefore, in the allocation unit 52, when the articles 80 of the same type supplied from the different trolleys 30 are used in different production groups G0, the article supply medium 70 for supplying the articles 80 is different for each trolley 30. It is preferable to assign the article supply medium 70 to each of the carriages 30.

In the above example, the allocation unit 52 allocates the article supply medium 70 (reel 121b and feeder 122b) for supplying the component 81b to the carriage 30a, and supplies the article supply medium 70 (reel) different from the article supply medium 70. 121d and feeder 122d) are assigned to the dolly 30b. As a result, the article management device 50 can reduce the replacement work of the article supply medium 70 that supplies the component 81b.

Further, in the present embodiment, since the same article supply medium 70 is used in a plurality of production groups G0, it is easy that the article 80 housed in the article supply medium 70 is insufficient. Therefore, when the remaining number of articles 80 housed in the article supply medium 70 allocated to the trolley 30 is a predetermined number or less, the allocation unit 52 supplies other articles of the same type as the article 80. It is advisable to preliminarily allocate the supply medium 70. As a result, the article management device 50 can reduce the situation where the article 80 is insufficient (for example, out of parts).

For example, if the board-to-board work by the board-to-board work machine WM0 is defective, the article 80 used for the board-to-board work may be discarded. Further, the board-to-board work machine WM0 may perform the board-to-board work again when the board-to-board work is defective. A spare number is set assuming such a case. When the remaining number of articles 80 housed in the article supply medium 70 is equal to or greater than the planned number of articles 80 to be supplied from the article supply medium 70, but is equal to or less than the addition value obtained by adding the spare number to the planned number of uses. There is a possibility that the article 80 will be in short supply (for example, out of parts). Therefore, the threshold value for determining the remaining number of articles 80 (the above-mentioned predetermined number) can be set to, for example, an added value obtained by adding a spare number to the planned number of articles 80 to be supplied from the article supply medium 70.

In any of the cases described above, the arrangement of the same article supply medium 70 in the production group G0 (production group G1 and production group G3) in which the carriage 30a is involved (arrangement of the reel 121 and the feeder 122 in the pallet member 33) is , Can be standardized. Similarly, the arrangement of the same article supply medium 70 (arrangement of the reel 121 and the feeder 122 in the pallet member 33) in the production group G0 (production group G2 and production group G4) in which the carriage 30b is involved can be made common. ..

1-3-3. Collation unit 53
When the article supply medium 70 is mounted on the trolley 30, the collating unit 53 determines whether or not the article supply medium 70 mounted on the trolley 30 is the article supply medium 70 assigned to the trolley 30 to be equipped. (Step S14 shown in FIG. 5). As a result, the article management device 50 can confirm the correctness of the article supply medium 70 mounted on the carriage 30.

For example, the worker transports the dolly 30 not connected to the parts supply device 12 to the storage FS0 shown in FIG. 1 to prepare for the production of the board product 900 of the next production group G0. Specifically, the worker equips the trolley 30 with the article supply medium 70 stored in the storage FS0. For example, the worker reads the identification code attached to the dolly 30 for identifying the dolly 30 by using a reading device. Further, the worker reads the identification code for identifying the article supply medium 70 attached to the article supply medium 70 by using a reading device, and equips the trolley 30 with the identification code. After the article supply medium 70 is mounted on the trolley 30, the operator can also read the identification code for identifying the article supply medium 70 attached to the article supply medium 70 by using a reading device.

The collation unit 53 acquires the information read by the reading device (identification information of the trolley 30 and identification information of the article supply medium 70). When the collating unit 53 allocates the article supply medium 70 to the trolley 30, the collating unit 53 correlates the identification information of the article supply medium 70 to be equipped assigned to the trolley 30 with the identification information of the trolley 30, and is shown in FIG. It is stored in the storage device DS0. When the identification information of the article supply medium 70 read by the reading device and the identification information of the article supply medium 70 stored in the storage device DS0 match, the collating unit 53 supplies the article to be mounted on the trolley 30. It is determined that the medium 70 is the article supply medium 70 assigned to the carriage 30 to be equipped.

Further, the collating unit 53 is mounted on the trolley 30 when the identification information of the article supply medium 70 read by the reading device and the identification information of the article supply medium 70 stored in the storage device DS0 do not match. It is determined that the article supply medium 70 is not the article supply medium 70 assigned to the carriage 30 to be equipped. In this case, the collation unit 53 shows the worker the above-mentioned determination result, and guides the worker to redo the work for the erroneously equipped article supply medium 70.

1-3-4. Deformation form of the division setting unit 51 For example, the component 81b shown in FIG. 6 is supplied from both the carriage 30a and the carriage 30b. The parts 81b supplied from the trolley 30a are used in the production group G1 and the production group G3. The parts 81b supplied from the carriage 30b are used in the production group G2 and the production group G4.

In this case, by changing the classification of the production group G0, the parts 81b may be supplied from the same trolley 30 (trolley 30a or trolley 30b). For example, in the production group G2, when the component 81b is used only in the unit production W05, the unit production W05 included in the production group G2 is moved to the production group G3. As a result, the parts 81b used in the unit production W05 can be supplied from the carriage 30a. Further, the unit production W0 in which the parts 81b are used can be aggregated, and the commonality of the articles 80 (including the article supply medium 70) used in the unit production W0 is increased.

In this way, the division setting unit 51 sets at least one unit production W0 using the article 80 included in the production group G0 into another production group G0 so that the commonality of the articles 80 used in the unit production W0 increases. It is also possible to move to (step S12 shown in FIG. 5). As a result, the article management device 50 can reduce the replacement work of the article supply medium 70 that supplies the article 80.

1-3-5. Production order change unit 54
In the above-mentioned example, the production order of the unit production W0 specified in the production plan L0 (in the order of unit production W01, unit production W02, unit production W03, ..., Unit production W09, unit production W10) is changed. It has not been. However, by changing the production order of the unit production W0, it may be possible to increase the commonality of the articles 80 used in the unit production W0.

For example, in the above example, by exchanging the unit production W05 included in the production group G2 and the unit production W06 included in the production group G3, the parts 81b used in the unit production W05 can be supplied from the trolley 30a. can. In this case as well, the unit production W0 in which the parts 81b are used can be aggregated, and the commonality of the articles 80 (including the article supply medium 70) used in the unit production W0 is increased.

In this way, the production order changing unit 54 can also change the production order of at least one unit production W0 using the article 80 so that the commonality of the articles 80 used in the unit production W0 increases (FIG. FIG. Step S11 shown in 5. As a result, the article management device 50 can reduce the replacement work of the article supply medium 70 that supplies the article 80. The production order changing unit 54 can change the production order of the unit production W0, and the division setting unit 51 can move the unit production W0 to another production group G0.

1-3-6. Others In the above-described example, the substrate working machine WM0 is a component mounting machine WM3 that mounts a component 81, which is an article 80, on a substrate 90. The article supply medium 70 is a feeder 122 (reel 121 and feeder 122 that supplies the component 81) equipped with a reel 121 that supplies the component 81.

The article supply medium 70 may be only the reel 121 or only the feeder 122. That is, the article supply medium 70 is at least one of the reel 121 and the feeder 122 that supply the component 81. However, the anti-board working machine WM0 is not limited to the component mounting machine WM3. Similarly, the article 80 is not limited as long as the anti-board working machine WM0 is an article necessary for the production of the substrate product 900. The article supply medium 70 may take various forms according to the article 80.

Further, in the above-described example, the two carriages 30 alternately supply the article supply medium 70 to the board working machine WM0. However, three or more carriages 30 can also supply the article supply medium 70 to the board working machine WM0 in any order. For example, in the production of a small-lot, high-mix substrate product 900, the production time per unit production W0 tends to be short, and the number of unit production W0 tends to increase. Since the maximum number of goods supply media 70 that can be mounted on one carriage 30 is determined by the carriage 30, there is also an upper limit on the number of unit production W0 that can be included in one production group G0.

Therefore, in the production of the low-volume, high-mix substrate product 900, the production time per production group G0 tends to be short. In this case, even if the production of the substrate product 900 of one production group G0 is completed, there is a possibility that the production preparation of the substrate product 900 of the next production group G0 is not completed. Therefore, it is preferable to increase the number of trolleys 30 to be used and equip the trolleys 30 with the necessary article supply medium 70 in advance.

For example, when three trolleys 30 are used, the first trolley 30, the second trolley 30, the third trolley 30, the first trolley 30, the second trolley 30, the third trolley 30, and so on. The two carts 30 can be used in a fixed order. Further, the order of use of the plurality of carriages 30 can be changed so that the commonality of the articles 80 used in the unit production W0 is increased. For example, when three trolleys 30 are used, the first trolley 30, the second trolley 30, the third trolley 30, the first trolley 30, the third trolley 30, and the second trolley 30 are used. You can also do it.

In the above-mentioned example, the dolly 30 is transported by an operator. However, the dolly 30 may be an automatic guided vehicle. Further, the worker may issue the article supply medium 70 stored in the storage FS0, or may issue the article supply medium 70 stored in the storage FS0. In the latter case, the storage FS0 discharges the article supply medium 70 assigned to the carriage 30 by the allocation unit 52.

Further, the trolley 30 which is an automatic guided vehicle can be moved to the storage FS0 and connected to the storage FS0. The storage FS0 equips the trolley 30 with the article supply medium 70 assigned by the allocation unit 52. When the article supply medium 70 is equipped, the trolley 30 separates from the storage FS0 and moves to the board working machine WM0. The carriage 30 is connected to the board working machine WM0 (for example, the parts supply device 12 of the parts mounting machine WM3). When the production of the substrate product 900 of the predetermined production group G0 is completed, the carriage 30 is separated from the substrate working machine WM0, and the above-mentioned process is repeated.

2. 2. Article management method The same applies to the article management method as described above for the article management device 50. Specifically, the article management method includes a classification setting process and an allocation process. The division setting step corresponds to the control performed by the division setting unit 51. The allocation process corresponds to the control performed by the allocation unit 52. Further, the article management method may include a collation step. The article management method may also include a production order changing step. The collation step corresponds to the control performed by the collation unit 53. The production order changing step corresponds to the control performed by the production order changing unit 54.

3. 3. An example of the effect of the embodiment According to the article management device 50, a classification setting unit 51 and an allocation unit 52 are provided. In particular, the allocation unit 52 is a trolley so that when the articles 80 of the same type supplied from the same trolley 30 are used in different production groups G0, the article supply medium 70 for supplying the articles 80 is the same. The article supply medium 70 is assigned to 30. As a result, the article management device 50 can reduce the replacement work of the article supply medium 70. The above-mentioned thing about the article management apparatus 50 can be said similarly about the article management method.
