1-4-1. Placement part 51
The placement unit 51 moves the stored articles 21 between the first storage unit 42t1 and the second storage unit 42t2 when it is necessary to improve the storage state of the storage box 40 (step S15 shown in FIG. 5). and step S16). The placement section 51 may take various forms as long as it can move the article 21 as described above.

As described above, when there is no space in the storage area of the first storage section 42t1, there is a possibility that the article 21 that can be stored in the first storage section 42t1 will be stored in the second storage section 42t2. There is a possibility that the storage efficiency of the articles 21 will decrease. The arranging unit 51 improves the storage state of the stocker 40 when the storage rate of the articles 21 in the first storage section 42t1 or the storage rate of the articles 21 in the second storage section 42t2 exceeds a preset allowable range. can decide that it is necessary to In addition, when the storage area of the first storage section 42t1 is full and the quantity or ratio of the articles 21 stored in the second storage section 42t2 exceeds a preset threshold value, the arrangement section 51 It can be determined that the storage condition of 40 needs to be improved. When an article 21 that can be stored in the first storage portion 42t1 is stored in the second storage portion 42t2 and there is an empty space in the first storage portion 42t1, the arrangement portion 51 stores the article in the second storage portion 42t2. The article 21 that has been stored can be moved to the first storage section 42t1.

Specifically, the arrangement unit 51 determines whether it is necessary to improve the storage condition of the stocker 40 (step S15). When it is necessary to improve the storage condition of the stocker 40 (Yes in step S15), the placement unit 51 uses the transfer device 40b to remove the first storage unit 42t1 stored in the second storage unit 42t2. The article 21 that can be stored in the first storage section 42t1 is moved to the empty first storage section 42t1 (step S16).

For example, as shown in FIG. 3C, the second storage section 42t2 of the storage 40 of the present embodiment is formed to be larger in width and depth than the first storage section 42t1. The height dimension of the second storage portion 42t2 is the same as that of the first storage portion 42t1. For example, when the article 21 is a reel 21a, the first storage section 42t1 can store the reel 21a with a predetermined reel diameter. The second storage portion 42t2 can store a reel 21a having a predetermined reel diameter and a reel 21a having a larger diameter than the reel 21a. In the above embodiment, the placement unit 51 uses the transfer device 40b to transfer the reel 21a having a predetermined reel diameter that can be stored in the first storage unit 42t1 stored in the second storage unit 42t2 to the empty first storage unit 42t1. It can be moved to the storage portion 42t1.

When the article 21 that can be stored in the first storage section 42t1 is not stored in the second storage section 42t2 (No in step S15), the control by the article storage device 50 does not perform the processing shown in step S16. And once it ends. Similarly, if an article 21 that can be stored in the first storage section 42t1 is stored in the second storage section 42t2, but there is no empty storage area that can store the article 21 in the first storage section 42t1, (step If S15 is No), the control by the article storage device 50 temporarily terminates without performing the process shown in step S16.

As described above, the second storage section 42t2 of the storage 40 of the present embodiment is formed to have larger width and depth dimensions than the first storage section 42t1. Moreover, the height dimension of the second storage portion 42t2 is formed to have the same height dimension as the first storage portion 42t1. However, the second storage portion 42t2 may be formed to be larger in height than the first storage portion 42t1. In this case, the width dimension and the depth dimension of the second storage portion 42t2 may be the same as those of the first storage portion 42t1, or may be formed larger than those of the first storage portion 42t1.

In a form in which the height dimension of the second storage portion 42t2 is formed to be larger than that of the first storage portion 42t1, for example, when the article 21 is a reel 21a, the first storage portion 42t1 is a reel 21a having a predetermined thickness t0. can be stored. The second storage portion 42t2 can store a reel 21a having a predetermined thickness t0 and a reel 21a having a thickness t0 that is thicker than the reel 21a. In this embodiment, the placement unit 51 uses the transfer device 40b to transfer the reel 21a having a predetermined thickness t0 that can be stored in the first storage unit 42t1 stored in the second storage unit 42t2. It can be moved to the part 42t1.

In addition, the placement section 51 can move the article 21 that is stored in the second storage section 42t2 and that can be stored in the first storage section 42t1 to an arbitrary empty first storage section 42t1. For example, the placement unit 51 can be stored in the first storage unit 42t1 stored in the second storage unit 42t2 so that the article 21 is stored from the first storage unit 42t1 near the loading/unloading unit 41 of the storage 40. object 21 can be moved. As a result, it is possible to shorten the distance traveled by the transfer device 40b when the article 21 is to be delivered, and shorten the time required for the delivery of the article 21 (the time required from the delivery request until the article 21 can be delivered). can do.

As shown in FIG. 3C, in the storage shed 40 of this embodiment, each storage unit 42u has a plurality of first storage sections 42t1 or a plurality of second storage sections 42t2 along the vertical direction (Z-axis direction). is provided. Further, as shown in FIG. 3A, the opening 41a and the placement section 40c of the loading/unloading section 41 are provided in the central portion of the storage 40 in the vertical direction (Z-axis direction). Further, the transfer device 40b is provided inside the storage unit 42u (the first storage portion 42t1 and the second storage portion 42t2) when viewed in the vertical direction (Z-axis direction).

Therefore, the arranging section 51 sequentially stores the articles 21 that can be stored in the first storage section 42t1 that is stored in the second storage section 42t2, starting from the empty first storage section 42t1 in the center in the vertical direction (Z-axis direction). can be moved. In addition, the arrangement portion 51 is stored in the first storage portion 42t1 stored in the second storage portion 42t2 in order from the empty first storage portion 42t1 of the storage unit 42u having the shortest distance from the placement portion 40c. Possible items 21 can also be moved. Furthermore, the arrangement portion 51 is arranged in the second storage portion 42t2 in order from the empty first storage portion 42t1 at the center in the vertical direction (Z-axis direction) of the storage unit 42u having the shortest distance from the mounting portion 40c. It is also possible to move the article 21 that can be stored in the first storage portion 42t1 that is stored.

In this way, the article storage device 50 can shorten the movement distance of the transfer device 40b when the article 21 is delivered, and can shorten the time required for the article 21 to be delivered. Therefore, the article storage apparatus 50 can achieve both improvement in storage efficiency of the articles 21 in the storage box 40 and reduction in the time required to take out the articles 21 .

In addition, the control device 40a of the storage 40 is communicably connected to the management device 19 shown in FIG. For example, the management device 19 notifies the control device 40a of the occurrence of a setup change in the board-related work line 10L. The management device 19 can also notify the control device 40a of the shortage of the articles 21 to be supplied to the board-related work line 10L. The management device 19 can also notify the control device 40a of the possibility that a setup change will occur during a predetermined period. The management device 19 can also notify the control device 40a of the possibility that the articles 21 will run short during a predetermined period. The control device 40a can also deliver the necessary articles 21 based on these notifications.

In the above-described embodiment, the arrangement portion 51 is stored in the second storage portions 42t2 so that the articles 21 scheduled to be delivered during setup change are stored in the plurality of adjacent first storage portions 42t1 and collected. It is also possible to move the article 21 that can be stored in the first storage portion 42t1. In addition, the arranging unit 51 is arranged so that the articles 21 scheduled to be delivered when there is a shortage of the articles 21 to be supplied to the board-related work line 10L are stored in the plurality of adjacent first storage sections 42t1 and aggregated. The article 21 that can be stored in the first storage portion 42t1 stored in the storage portion 42t2 can also be moved. Furthermore, the arrangement unit 51 stores the articles 21 to be delivered when there is a possibility of a setup change or a shortage of the articles 21 to be supplied to the board-oriented work line 10L. The articles 21 that can be stored in the first storage portion 42t1 stored in the second storage portion 42t2 can also be moved so that they are stored and collected.

In addition, the placement section 51 is stored in the second storage section 42t2 so that the articles 21 scheduled to be delivered for each board-related work line 10L are stored in a plurality of adjacent first storage sections 42t1 and aggregated. The article 21 that can be stored in the first storage portion 42t1 can also be moved. Further, the arrangement portion 51 is stored in the second storage portion 42t2 so that the articles 21 scheduled to be delivered for each board-oriented work machine 10 are stored in the plurality of adjacent first storage portions 42t1 and collected. The article 21 that can be stored in the first storage portion 42t1 can also be moved.

1-4-2. moving part 52
As the storage 40 is used, the items 21 to be stored may change, and the size (width, depth and height) of the first storage section 42t1 required for the storage 40 may change. Similarly, as the storage 40 is used, the items 21 to be stored may change, and the size of the second storage section 42t2 required for the storage 40 may change.

As shown in FIG. 3C, the storage 40 of this embodiment includes a plurality of first storage sections 42t1 partitioned by partition members 42b and a plurality of second storage sections 42t2 partitioned by partition members 42b. I have. In this form, it is easier to increase or decrease the height dimension of the first storage portion 42t1 compared to the case of increasing or decreasing the width dimension or the depth dimension of the first storage portion 42t1. Similarly, it is easier to increase or decrease the height dimension of the second storage portion 42t2 than to increase or decrease the width dimension or the depth dimension of the second storage portion 42t2.

Therefore, the article storage device 50 of this embodiment is provided with a moving section 52 . The moving unit 52 moves the partition member 42b so as to increase the number of the first storage units 42t1 or the second storage units 42t2 that can store the articles 21 that have been stored in and out of the warehouse 40 for a predetermined number of times or more. Let As described above, the control device 40a increments the number of times the article 21 is delivered to the storage device 53m and stores it in the storage device 53m. Therefore, the moving unit 52 can acquire information about the number and thickness of the articles 21 that have been stored/retrieved a predetermined number of times or more, and the thickness of the articles 21 from the storage device 53m.

Then, the moving unit 52 determines whether or not it is necessary to move the partition member 42b (step S13 shown in FIG. 5). For example, if the necessary number of the first storage units 42t1 or the second storage units 42t2 that can store the articles 21 that have been stored in and out a predetermined number of times or more are not secured in the storage 40, the moving unit 52 moves the partition member 42b. You can decide that you need to move. Conversely, when the necessary number of the first storage units 42t1 and the second storage units 42t2 capable of storing the articles 21 that have been stored/retrieved a predetermined number of times or more are secured in the storage shed 40, the moving unit 52 includes the partition member 42b. can be determined to be unnecessary.

When the partition member 42b needs to be moved (Yes in step S13), the moving unit 52 moves the partition member 42b in accordance with the increased height dimension of the first storage portion 42t1 or the second storage portion 42t2. (Step S14). The moving part 52 may take various forms as long as it can move the partition member 42b as described above. For example, slits are formed at regular intervals in the storage unit 42u, and the partition members 42b are inserted into the slits so that the distance between adjacent partition members 42b is a predetermined distance. In this form, the moving unit 52 reinserts the partition member 42b into the predetermined slit using a transfer device similar to the transfer device 40b. When the partition member 42b is inserted into the predetermined slit, the distance between the adjacent partition members 42b matches the increased height dimension of the first storage portion 42t1 or the second storage portion 42t2.

The storage unit 42u can also include an elevating mechanism capable of moving the partition members 42b in the vertical direction (Z-axis direction). In this form, the moving part 52 uses an elevating mechanism to move the partition members 42b so that the distance between the adjacent partition members 42b matches the height dimension of the first storage part 42t1 or the second storage part 42t2 to be increased. to move. If the movement of the partition member 42b is unnecessary (No in step S13), the control by the article storage device 50 proceeds to the determination shown in step S15 without performing the processing shown in step S14.

For example, as shown in FIG. 2B, a component tape 21a2 containing components to be mounted on the board 90 is wound around the reel 21a. The thickness t0 of the reel 21a varies according to the width dimension of the component tape 21a2. Therefore, the height dimension of the first storage portion 42t1 or the second storage portion 42t2 required for the storage 40 tends to change as the storage 40 is used. Therefore, when the article 21 is a reel 21a, the moving unit 52 preferably moves the partition member 42b according to the thickness t0 of the reel 21a whose number of times of entering and leaving the warehouse is equal to or greater than a predetermined number of times. As a result, the article storage apparatus 50 can increase the number of the first storage section 42t1 or the second storage section 42t2 that can store the reels 21a that have been stored in and out of the storage 40 for a predetermined number of times or more.

1-4-3. Storage unit 53 and initial placement unit 54
As described above, the closer the storage area is to the loading/unloading section 41 of the storage 40, the shorter the movement distance of the transfer device 40b when the article 21 is to be delivered, and the time required to deliver the article 21 is shortened. . The above matters are not limited to the forms already described. Therefore, the article storage device 50 of the present embodiment includes a storage section 53 and an initial placement section 54 in order to take the above matters into consideration when determining the initial storage area of the article 21 in the storage section 42 as well.

The storage unit 53 causes the storage device 53m to store the number of times the article 21 has entered/exited the storage 40 (step S11 shown in FIG. 5). As described above, for example, the storage unit 53 adds one to the number of times the article 21 is delivered when the article 21 is delivered, and stores the result in the storage device 53m. The storage device 53m stores the number of times the articles 21 have been put in and taken out for each type. Based on the number of times of entering and leaving the warehouse stored in the storage device 53m, the initial placement unit 54 stores the article 21 with the higher number of times of entering and leaving in the storage area closer to the entering and leaving unit 41 of the stocker 40 (step S12).

The initial placement section 54 can store articles 21 that have been stored and retrieved more frequently in a storage area closer to the storage section 41 of the stocker 40 in the same manner as in the above-described mode. Specifically, the initial placement unit 54 can store the article 21 that has been stored and retrieved more frequently in a storage area closer to the center in the vertical direction (Z-axis direction) of the storage unit 42u. In addition, the initial placement section 54 can also store articles 21 that have been stored and taken out more frequently in the storage area of the storage unit 42u that is closer to the placement section 40c. In addition, the initial placement unit 54 stores articles 21 that have been stored in and out more frequently in a storage area closer to the center in the vertical direction (Z-axis direction) of the storage unit 42u with a shorter distance from the placement unit 40c. can also

It should be noted that the initial placement unit 54 can determine the storage area for the articles 21 after a considerable number of articles 21 that can be statistically analyzed have entered/exited the storage 40 . Therefore, when the operation of the storage warehouse 40 is newly started, the initial placement unit 54 stores the number of times the articles 21 have been stored in the storage device 53m for the storage warehouse 40 that is already in operation. A storage area can be determined. The storage warehouse 40 that is already in operation is preferably a storage warehouse 40 that can store articles 21 that are the same as the articles 21 that are scheduled to be stored in the storage warehouse 40 that will start operating from now on.

When the article storage device 50 includes the storage unit 53 and the initial placement unit 54, the placement unit 51 can take the following forms. For example, the arranging unit 51 totalizes the number of times of entering and leaving the warehouse stored in the storage device 53m for each predetermined period. The storage area can be moved to a storage area closer to the loading/unloading section 41 than the storage area determined by the section 54 . The predetermined period can be arbitrarily set, for example, one week, one month, or the like.

The placement unit 51 of the present embodiment is arranged such that when an article 21 that can be stored in the first storage unit 42t1 is stored in the second storage unit 42t2 and there is an empty space in the first storage unit 42t1, the second storage unit 51 The article 21 stored in the portion 42t2 is moved to the first storage portion 42t1. In this form, the arranging unit 51 determines that the storage area determined by the initial arranging unit 54 is the article 21 having a larger increase in the number of times or rate of increase in the number of times of entering/exiting compared to the time of past aggregation (for example, the time of the previous aggregation). It can be moved to a storage area (first storage section 42t1) closer to the loading/unloading section 41 by comparison.

In addition, when the shortened time required for shipping the article 21 by changing the storage area from the storage area determined by the initial placement section 54 is equal to or greater than the predetermined time, the placement section 51 can also be moved. As a result, the article storage apparatus 50 can move the article 21 when a predetermined effect is obtained by changing the storage area, and can reduce the number of times the article 21 is moved.

The arranging unit 51 can also move the article 21 when the required time until the article 21 is delivered is equal to or longer than the prescribed time. As a result, the article storage device 50 can move the article 21 when the storage area needs to be changed, and can reduce the number of times the article 21 is moved. It should be noted that the threshold value (the above-mentioned predetermined time and specified time) for determining whether or not to move the article 21 can be arbitrarily set, and can be derived in advance by simulation, verification using an actual machine, or the like.

In addition, the arranging unit 51 can also move the article 21 to a time zone specified by the user or a time zone in which the number of times the articles 21 are put in and taken out is expected to be equal to or less than a specified number of times. As a result, the article storage device 50 can reduce the influence on the normal loading and unloading of the articles 21 using the transfer device 40b.

For example, the user can use the touch panel (the display device 40e that functions as an input device) to designate an arbitrary time period for moving the article 21. In addition, for example, a time period such as night when there is less set-up work and fewer articles 21 are put in and out than in the daytime is included in the time period in which the number of times the articles 21 are put in and taken out is expected to be equal to or less than the specified number of times. The specified number of times can be arbitrarily set, and can be derived in advance by simulation, verification using an actual machine, or the like.

2. Modification A modification of the storage 40 includes a tray storage section 42 t 3 capable of storing the tray 60 . In addition, when the storage condition of the stocker 40 needs to be improved, the arrangement unit 51 of the modified form is a target tray 60 that stores articles 21 that are less than the maximum number of articles 21 that can be accommodated. The article 21 stored between 60t is moved. In the modified form, differences from the embodiment are mainly described, and redundant description is omitted.

2-1. tray 60
The tray 60 accommodates the articles 21 used in the board-related work machine 10 that performs predetermined board-related work on the board 90 . The tray 60 may take various forms as long as it can accommodate the articles 21 . The tray 60 has a first accommodation portion 61 capable of accommodating at least one type of article 21 (in the case of the reel 21a, referred to as a first reel 21f in this specification) among a plurality of types of articles 21 having different outer dimensions. be prepared. The tray 60 holds at least one type of article 21 (in the case of the reel 21a, referred to as the second reel 21s in this specification) having a size equal to or greater than the outer dimensions of the article 21 (the article 21 that can be accommodated in the first accommodation portion 61). ) can be accommodated, and a second accommodation portion 62 larger than the first accommodation portion 61 can be provided. The tray 60 can also have both the first compartment 61 and the second compartment 62 .

The tray 60 shown in FIGS. 6 to 8 includes both a first storage section 61 and a second storage section 62. The tray 60 may also include pin members 63 . The tray 60 may also include

cutouts

64,64. As shown in FIG. 7, the tray 60 includes a first housing portion 61, a second housing portion 62, a pin member 63, and

notches

64,64. The first accommodation portion 61 and the second accommodation portion 62 can take various forms. The second accommodation portion 62 shown in FIG. 7 is provided above the first accommodation portion 61 in the vertical direction (the Z-axis direction) so as to be continuous with the accommodation space of the first accommodation portion 61 . The first accommodation portion 61 is formed with a first recess 61a capable of accommodating the first reel 21f. Further, the second housing portion 62 is formed with a second recess 62a capable of housing the second reel 21s.

Since the reel 21a has a columnar shape, the first recess 61a is formed as a cylindrical recess (a general shape excluding

notch portions

64, 64 described later) having a slightly larger diameter than the outer diameter of the first reel 21f. there is The second recess 62a is formed in a cylindrical recess having a slightly larger diameter than the outer diameter of the second reel 21s. Above the first accommodation portion 61 in the vertical direction (Z-axis direction), the second accommodation portion 62 is provided continuously with the accommodation space of the first accommodation portion 61, so that the bottom surface 61b of the first recess 61a and the second recess A bottom surface 62b of 62a is formed in a stepped shape.

The tray 60 can include at least one first storage portion 61 and at least one second storage portion 62 . A tray 60 shown in FIG. 7 includes a plurality of (four in the figure) first housing portions 61 and one second housing portion 62 . Further, the tray 60 includes a main body portion 60a having a square shape (rough shape excluding

notch portions

64, 64 described later) when viewed in the vertical direction (Z-axis direction), a plurality of (four) first accommodating portions 61, One second housing portion 62 is formed.

At least one first reel 21f can be accommodated in one first accommodating portion 61. At least one second reel 21 s can be accommodated in one second accommodating portion 62 . As the number of first reels 21f accommodated in one first accommodating portion 61 increases, the work of removing the first reels 21f accommodated in the first accommodating portion 61 becomes more complicated. Moreover, as the number of first reels 21f accommodated in one first accommodation portion 61 increases, the management of the first reels 21f becomes more complicated. What has been described above also applies to the second reel 21 s housed in the second housing portion 62 .

Therefore, as shown in FIG. 8, each of the plurality (four) of the first accommodation portions 61 is set to have a height dimension H1 so as to accommodate one first reel 21f, and one second accommodation portion 62 is , the height dimension H2 is preferably set so as to accommodate one second reel 21s. Also, it is preferable that one tray 60 accommodates either the first reel 21f or the second reel 21s. This facilitates the work of removing the desired reel 21a from the tray 60, and facilitates the management of the reels 21a.

As shown in FIG. 8, the first accommodating portion 61 and the second accommodating portion 62 are arranged such that the axial direction (arrow R direction) of the rotation axis R0 of the reel 21a is aligned with the vertical direction (Z-axis direction). 21a can be accommodated. In addition, as shown in FIG. 6, the first accommodation portion 61 has the same circumference around the rotation axis R0 of the second reel 21s accommodated in the second accommodation portion 62 when viewed in the vertical direction (Z-axis direction). The rotation axis R0 of the first reel 21f housed in the first housing portion 61 is positioned above (on the circle CL0). As a result, the tray 60 can efficiently accommodate a plurality of types of reels 21a having different outer dimensions (reel diameters) in the vertical direction (Z-axis direction).

Also, even if the reels 21a have the same external dimensions (reel diameter), the component tapes 21a2 may have different width dimensions, and the reels 21a may have different height dimensions (thickness t0). For example, if the height dimension of the first accommodation portion 61 is set to match the maximum height dimension (thickness t0) of the first reel 21f to be used, a gap is likely to occur in the first accommodation portion 61 . What has been described above also applies to the height dimension of the second accommodation portion 62 . Therefore, at least one of the first storage portion 61 and the second storage portion 62 has a height dimension set according to the minimum height dimension RH0 (minimum thickness t0) of the article 21 (reel 21a). and good. As a result, the gap between the trays 60 can be easily reduced, and the storage efficiency of the trays 60 can be improved.

The height dimension H1 of the first accommodation portion 61 shown in FIG. 8 is set according to the minimum height dimension RH0 (minimum height dimension RH1) of the first reel 21f. In addition, the height dimension H2 of the second accommodation portion 62 is set according to the minimum height dimension RH0 (minimum height dimension RH2) of the second reel 21s. If the height dimension (thickness t0) of the first reel 21f accommodated in the first accommodation portion 61 is greater than the minimum height dimension RH1, the first reel 21f erodes at least the second accommodation portion 62. As shown in FIG. In this case, the second storage portion 62 does not store the second reel 21s. Further, when the height dimension (thickness t0) of the second reel 21s accommodated in the second accommodation portion 62 is larger than the minimum height dimension RH2, the second reel 21s is accommodated in a state of protruding from the tray 60.

A plurality of types of first reels 21f with different outer dimensions (reel diameters) can be accommodated in the first accommodating portion 61. Similarly, the second accommodation portion 62 can accommodate a plurality of types of second reels 21s having different outer dimensions (reel diameters). For example, at least one of the first accommodation portion 61 and the second accommodation portion 62 may be provided with the pin member 63 . The pin member 63 is inserted into the support hole of the reel 21a when the reel 21a is accommodated.

The pin member 63 is formed in a cylindrical shape, and the outer diameter of the pin member 63 is set slightly smaller than the outer diameter of the support hole of the reel 21a. Also, the height dimension of the pin member 63 provided in the first accommodation portion 61 is set smaller than the height dimension H1 of the first accommodation portion 61 . Similarly, the height dimension of the pin member 63 provided in the second housing portion 62 is set smaller than the height dimension H2 of the second housing portion 62 . The tray 60 shown in FIG. 7 has a pin member 63 in the second housing portion 62 . As a result, the second accommodation portion 62 can accommodate a plurality of types of second reels 21s having different outer dimensions (reel diameters).

A first accommodating portion 61 is provided so as to accommodate a reel 21a having the smallest external dimension among the reels 21a used in the production of circuit board products (the reel 21a having the smallest reel diameter, which is referred to as the smallest reel in this specification). external dimensions are set. In addition, the reel 21a having the largest external dimensions among the reels 21a used in the production of board products (the reel 21a having the largest reel diameter, which is referred to as the largest reel in this specification) can be accommodated. External dimensions of the portion 62 are set. The body portion 60 a is set slightly larger than the outer dimensions of the second housing portion 62 . Further, a pin member 63 is provided in the second accommodation portion 62 .

Therefore, the outer dimensions of the tray 60 can be set according to the outer dimensions (reel diameter) of the maximum reel. Also, for example, the outer dimension (reel diameter) of the smallest reel is approximately half the outer dimension (reel diameter) of the largest reel. Therefore, in one tray 60, it is easy to arrange a plurality (four) of the first accommodating portions 61 evenly, and to easily accommodate a plurality (four) of minimum reels. Furthermore, since the second accommodation portion 62 is provided with the pin member 63, the operator can select a plurality of types of second reels 21s whose external dimensions (reel diameter) are larger than the minimum reel and equal to or smaller than the maximum reel. The reel 21s can be accommodated in the second accommodation portion 62 without worrying about the external dimensions (reel diameter). Incidentally, as shown in FIGS. 6 and 7, the tray 60 is provided with a specific code 23 by which the tray 60 can be identified. An identification code 22 is attached to the reel 21a.

2-2. Storage 40
The stocker 40 may be provided with a tray storage section 42t3 capable of storing the tray 60 storing the articles 21, and may take various forms. The stocker 40 includes a loading/unloading section 41, a storage section 42, a control device 40a, a transfer device 40b, a reading device 40d, and a display device 40e. The loading/unloading section 41 includes an opening 41a and a placement section 40c. However, as shown in FIGS. 9 and 10, the modified storage box 40 is formed in, for example, a dodecagonal prism shape. FIG. 9 is an enlarged view enlarging a part of the storage unit 42u. As shown in the figure, the storage unit 42u includes a pair of

support members

42c, 42c that support both

ends

60e, 60e of the tray 60 in the width direction (arrow TW direction). The tray 60 is inserted into a pair of

slits

42d, 42d formed at the same height in a pair of

support members

42c, 42c, and both

ends

60e, 60e are supported.

Specifically, as shown in FIGS. 7 and 9, both ends 60e, 60e of the tray 60 are formed with a pair of protrusions 60e1, 60e1 that protrude in the width direction (arrow TW direction). The projections 60e1, 60e1 are inserted into a pair of

slits

42d, 42d formed at the same height, and the tray 60 is supported at both

ends

60e, 60e. Thereby, the storage section 42 can store each of the plurality of trays 60 in the predetermined tray storage section 42t3. In addition, the storage section 42 can store a plurality of trays 60 in the vertical direction (Z-axis direction) while minimizing the gap in the vertical direction (Z-axis direction).

Furthermore, as shown in FIG. 10, the storage section 42 includes a plurality of (six in the figure) storage units 42u. Each of the plurality (six) of storage units 42u is provided with a plurality of tray storage portions 42t3 along the vertical direction (Z-axis direction). As shown in the figure, a plurality (six) of storage units 42u are arranged in a circle when viewed in the vertical direction (Z-axis direction). In this form, the more the plurality (six) of storage units 42u arranged in a circle are arranged toward the center, the more likely the tray 60 will interfere with the adjacent tray 60 when stored in the tray storage portion 42t3. become more sexual. Therefore, it is preferable that the tray 60 has

notches

2-3. Placement part 51
When it is necessary to improve the storage condition of the stocker 40, the arranging unit 51 stores the articles 21 among the target trays 60t, which are the trays 60 in which the articles 21 smaller than the maximum number of articles 21 that can be accommodated are stored. The article 21 that is held is moved (corresponding to steps S15 and S16 shown in FIG. 5).

The placement section 51 may take various forms as long as it can move the article 21 as described above. For example, in the tray 60 shown in FIGS. 6 to 8, a maximum of four reels 21a (first reels 21f) can be accommodated in the first accommodating portion 61 in one tray 60. FIG. In this way, the stocker 40 stores the target tray 60t containing articles 21 (reels 21a) that are smaller than the maximum number (in this case, four) of articles 21 (reels 21a) that can be accommodated. In this case, the storage efficiency of the articles 21 (reels 21a) in the stocker 40 may decrease. The placement unit 51 can determine that the storage state of the storage 40 needs to be improved when the number or ratio of the target trays 60t stored in the storage 40 exceeds a preset threshold value. can.

The placement unit 51 can move the article 21 (reel 21a) accommodated in the target tray 60t to another target tray 60t so that an empty tray 60 in which no article 21 (reel 21a) is accommodated is generated. can. Specifically, the placement unit 51 determines whether it is necessary to improve the storage state of the storage box 40 (corresponding to step S15 shown in FIG. 5). If it is necessary to improve the storage condition of the stocker 40 (corresponding to Yes in step S15), the placement section 51 is stored in the target tray 60t using the transfer device 40b and the reel transfer device. The article 21 (reel 21a) is moved to another target tray 60t (corresponding to step S16).

For example, the reel transfer device is provided on the placement section 40c. The reel transfer device sucks the article 21 (reel 21a) housed in the target tray 60t moved to the placement section 40c by the transfer device 40b, and moves the article 21 (reel 21a) to the standby location. . The reel transfer device accommodates the article 21 (reel 21a) in another target tray 60t moved to the placement section 40c by the transfer device 40b. By repeating the above-described control, the arranging section 51 can collect the articles 21 (reels 21a) accommodated in the target tray 60t to another target tray 60t. As a result, there are empty trays 60 in which articles 21 (reels 21a) are not stored, and the number of target trays 60t is reduced.

As shown in FIG. 9, in the storage section 42, a plurality of tray storage sections 42t3 are provided along the vertical direction (Z-axis direction). Therefore, there is a possibility that the upper end portion 21t of the article 21 (reel 21a) stored in the tray 60 stored in the tray storage portion 42t3 may erode another tray storage portion 42t3 adjacent in the vertical direction (Z-axis direction). There is

For example, at least one of the first storage portion 61 and the second storage portion 62 has a height dimension set according to the minimum height dimension RH0 of the article 21 (reel 21a), and mainly the second reel 21s may be accommodated in a state of protruding from the tray 60 . Therefore, in the article storage device 50, the upper end portion 21t of the article 21 (reel 21a) accommodated in the tray 60 accommodated in the tray accommodation section 42t3 is placed in another tray accommodation section adjacent in the vertical direction (Z-axis direction). 42t3, the storage of the tray 60 in another tray storage portion 42t3 adjacent in the vertical direction (Z-axis direction) is restricted.

As a result, the upper end portion 21t of the article 21 (reel 21a) stored in the tray 60 stored in the tray storage portion 42t3 is stored in another tray storage portion 42t3 adjacent in the vertical direction (Z-axis direction). Interference with the tray 60 can be avoided. The article 21 (reel 21a) encroaching on the adjacent tray storage portion 42t3 is mainly assumed to be the second reel 21s, but may also be the first reel 21f.

Here, the first tray is the tray 60 in which the upper end 21t of the stored article 21 (reel 21a) erodes another tray storage section 42t3 adjacent in the vertical direction (Z-axis direction). Also, the tray storage portion 42t3 in which the first tray is stored is referred to as the first tray storage portion. Further, another tray housing portion 42t3 adjacent to the first tray housing portion in the vertical direction (Z-axis direction) is referred to as a second tray housing portion. For example, when the first tray is taken out and another first tray is stored in the first tray storage portion, the storage regulation of the tray 60 in the second tray storage portion should be continued. On the other hand, when the first tray is taken out and the tray 60 in which the upper end portion 21t of the article 21 (reel 21a) does not erode the second tray storage portion is stored in the first tray storage portion, the second tray storage portion , can be released.

After the first tray is taken out, it is often uncertain which of the above trays 60 will be stored in the first tray storage section. Therefore, the arrangement unit 51 arranges the trays 60 so that the trays 60 storing the articles 21 (reels 21a) are stored in the plurality of tray storage units 42t3 adjacent to each other in the vertical direction (the Z-axis direction) and collected. It's good to move. This makes it easier to form a plurality of empty tray storage portions 42t3 adjacent in the vertical direction (Z-axis direction) including the first tray storage portion and the second tray storage portion after the first tray is delivered.

It should be noted that the article storage device 50 of the modified form can also be provided with the storage unit 53 and the initial placement unit 54 (corresponding to steps S11 and S12 shown in FIG. 5). However, there is a possibility that multiple types of articles 21 may be accommodated in one tray 60 . Therefore, the storage unit 53 stores the number of times the articles 21 stored in the tray 60 are stored in and out for each type. In addition, the placement unit 51 totalizes the number of times of entering and leaving the warehouse stored in the storage device 53m for each predetermined period. The storage area can be moved to a storage area closer to the loading/unloading section 41 than the storage area determined by the section 54 .

The placement unit 51 of the modified form moves the article 21 accommodated in the target tray 60t to another target tray 60t so that an empty tray 60 in which no article 21 is accommodated is generated. In this form, the arranging unit 51 selects the articles 21 (the trays 60 where the target tray 60t has been accommodated) that have increased in the number of times or the rate of increase in the number of times of entering and leaving the warehouse compared to the time of past aggregation (for example, the time of the previous aggregation). The closer the article 21) is to the storage area determined by the initial placement unit 54, the closer the storage area (tray storage unit 42t3) to the loading/unloading unit 41 can be.

In addition, when the shortened time required for shipping the article 21 by changing the storage area from the storage area determined by the initial placement section 54 is equal to or greater than the predetermined time, the placement section 51 (Articles 21 housed in the tray 60 from which the target tray 60t has been removed) can also be moved. The arranging unit 51 can also move the article 21 (the article 21 stored in the tray 60 from which the target tray 60t is cleared) when the required time until the article 21 is delivered is equal to or longer than the specified time. . In addition, the arranging unit 51 determines whether the article 21 (the target tray 60t is accommodated in the tray 60 in which the target tray 60t is cleared) is specified by the user or the time period in which the number of times the article 21 is expected to enter and exit the warehouse is equal to or less than the specified number of times. It is also possible to move the article 21) that is being held.

3. Others In the form described above, the case where the article 21 is the reel 21a is mainly described as an example. However, the article 21 may be, for example, the component tray 21b already described. Alternatively, the tray 60 may include only the first storage portion 61 out of the first storage portion 61 and the second storage portion 62 . The tray 60 can also include only the second storage portion 62 out of the first storage portion 61 and the second storage portion 62 .

4. Example of Effects of Embodiments and Modified Modes According to the article storage device 50 , the storage box 40 and the placement section 51 are provided. As a result, the article storage device 50 can improve the storage efficiency of the articles 21 in the storage box 40 .
