Description

[Technical field]

[0001] This specification discloses a technique relating to an item storage device. [Background technology]

[0002] The automated warehouse management system described in Patent Document 1 utilizes idle time between the entry and exit of items to move items with earlier scheduled delivery dates and times to shelves closer to the delivery station. In this way, the automated warehouse management system described in Patent Document 1 aims to shorten the time from a delivery request to the completion of delivery.

[0003] In the automated warehouse described in Patent Document 2, the shelves of the automated warehouse are divided into a short-term zone close to the output station and a medium- to long-term zone away from the output station. The automated warehouse described in Patent Document 2 sets the number of items scheduled to be output for one day as the safety stock amount, and moves stored items from the medium- to long-term zone to the short-term zone during designated times such as at night or during lunch breaks. In this way, the automated warehouse described in Patent Document 2 aims to shorten the waiting time until output by replenishing the shortage of the safety stock amount during times of low load.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] 1. Embodiment 1 shows an example of a board production facility 80 to which an article storage device 50 is applied. The board production facility 80 shown in FIG. 1 includes a substrate-related operation line 10L equipped with a substrate-related operation machine 10, a receiving section 20, a transport vehicle 30, and a storage facility 40.

[0012] 1-1. Substrate work line 10L In the substrate-related work line 10L, substrate-related work machines 10 perform a predetermined substrate-related work on a substrate 90. There is no limitation on the type and number of substrate-related work machines 10. As shown in Fig. 1, the substrate-related work line 10L of the present embodiment includes a plurality of (five) substrate-related work machines 10, including a printer 10a, a print inspection machine 10b, a component mounting machine 10c, a reflow furnace 10d, and a visual inspection machine 10e, and the substrate 90 is transported in the above order by a substrate transport device.

[0013] The printer 10a prints solder at component mounting positions on the board 90. The print inspection machine 10b inspects the printing condition of the solder printed by the printer 10a. The component mounting machine 10c mounts multiple components on the board 90 on which the solder has been printed. There may be one component mounting machine 10c or multiple component mounting machines 10c. When multiple component mounting machines 10c are provided, the multiple component mounting machines 10c can share the task of mounting multiple components on the board 90.

[0014] The component mounting machine 10c includes a component supplying device that supplies components to be mounted on the board 90. The component supplying device can supply components using, for example, a feeder including a reel 21a shown in FIGS. 2A and 2B, or a component tray 21b on which components are arranged as shown in FIG. 2C. The reel 21a has a main body 21a1 on which a component tape 21a2 that contains the components to be mounted on the board 90 is wound. The reel 21a is rotatably and detachably provided on the feeder. The leading end of the component tape 21a2 is pulled out to a component removal section provided on the feeder, and the components are sequentially supplied. The reel 21a can supply relatively small components such as chip components.

[0015] Components are arranged on the component tray 21b. The component tray 21b can supply relatively large components such as QFPs (Quad Flat Packages) and BGAs (Ball Grid Arrays). The reflow furnace 10d heats the board 90 on which the components have been mounted by the component mounting machine 10c, melting the solder and performing soldering. The appearance inspection machine 10e inspects the mounting state of the components mounted on the board 90 by the component mounting machine 10c.

[0016] In this way, the substrate-related work line 10L can use a plurality (five) of substrate-related work machines 10 to sequentially transport substrates 90 and perform production processes including inspection processes to produce substrate products. Note that the substrate-related work line 10L can also include substrate-related work machines 10 such as a functional inspection machine, a buffer device, a substrate supply device, a substrate reversing device, a shield mounting device, an adhesive application device, and an ultraviolet ray irradiation device, as necessary.

[0017] The plurality (five) of substrate-related performing machines 10 constituting the substrate-related performing line 10L and the management device 19 are provided so as to be able to communicate with each other by wired or wireless communication units. The management device 19 controls the plurality (five) of substrate-related performing machines 10 constituting the substrate-related performing line 10L and monitors the operating status of the substrate-related performing line 10L. The management device 19 stores various control data for controlling the plurality (five) of substrate-related performing machines 10. The management device 19 transmits the control data to each of the plurality (five) of substrate-related performing machines 10. Furthermore, each of the plurality (five) of substrate-related performing machines 10 transmits its operating status and production status to the management device 19.

[0018] 1-2. Receiving section 20 and transport vehicle 30 For example, when the item 21 arrives at the receiving section 20, the receiving operation described below is performed. Then, the item 21 is, for example, stored in a storage case, loaded onto the transport vehicle 30, and transported to the storage facility 40. After being stored in the storage facility 40, the item 21 is supplied to the substrate-related work line 10L as necessary.

[0019] The item 21 is not limited as long as it is used in the substrate-related operation machine 10. For example, the substrate-related operation line 10L is equipped with a component mounting machine 10c. In this case, the item 21 includes a reel 21a on which a component tape 21a2 is wound, which contains the components to be mounted on the substrate 90. The item 21 also includes a component tray 21b on which the components are arranged. As shown in FIGS. 2A and 2C, an identification code 22 capable of identifying the item 21 is attached to the item 21. The identification code 22 may be, for example, a one-dimensional code, a two-dimensional code, or a wireless tag.

[0020] Specifically, when the item 21 arrives at the receiving section 20, the worker issues identification information using, for example, an item management device. The worker also uses a barcode reader or the like to read a barcode or the like attached to the item 21 by the supplier (vendor). The worker can also obtain the item information from a database in which item information related to the item 21 is registered. The worker uses the item management device to issue an identification code 22 that includes at least the identification information and the item information.

[0021] The worker attaches an identification code 22 including at least identification information to a surface of the article 21, and stores the article 21 in a storage case. The storage case may take various forms as long as it is capable of storing at least one article 21. The storage case may be a tray 60, which will be described later. The storage case is also provided with a specific code 23 that can identify the storage case. The specific code 23 may be, for example, a one-dimensional code, a two-dimensional code, or a wireless tag.

[0022] The worker loads the storage case containing the item 21 onto the transport vehicle 30. For example, the transport vehicle 30 can be towed by the worker. An automated transport vehicle capable of automatic travel can also be used as the transport vehicle 30. Note that the transport vehicle 30 can also transport the item 21 to the storage facility 40 without using a storage case. Also, the worker can transport the item 21 to the storage facility 40 without using the transport vehicle 30. Furthermore, at least a part of the work performed by the worker described above can be automated using a transport device (e.g., a belt conveyor), an actuator (e.g., a robot arm), an item management device, etc.

[0023] 1-3. Storage 40 The storage 40 may take various forms as long as it is capable of storing the item 21. As shown in Fig. 3A to Fig. 3C, the storage 40 of this embodiment is formed, for example, in an octagonal prism shape. Note that in Fig. 3C, the top of the storage 40 is open, and the interior of the storage 40 is shown.

[0024] The storage facility 40 of this embodiment includes an entry / exit section 41, a storage section 42, a control device 40a, a transfer device 40b, a reading device 40d, and a display device 40e. The entry / exit section 41 includes an opening 41a and a placement section 40c, through which the item 21 is entered and removed. As shown in FIG. 3A, an opening 41a is provided on the front side of the storage facility 40. The opening 41a is formed larger than the item 21 so that the item 21 can be entered or removed. The storage facility 40 may also have an exit port provided at an opening different from the opening 41a through which the item 21 is entered.

[0025] As shown in Fig. 3B, the placement section 40c is provided in the work space near the opening 41a. The placement section 40c can temporarily place the item 21 when the item 21 is stored or removed from the warehouse. For example, the storing operation of the item 21, which involves bringing in the item 21 and placing it on the placement section 40c, can be performed by a worker. Also, the unloading operation of the item 21, which involves removing the item 21 placed on the placement section 40c, can be performed by a worker in the same manner as the storing operation.

[0026] A reading device 40d is provided above the placement section 40c. When the item 21 enters the storage 40 through the opening 41a, the reading device 40d reads the identification code 22 attached to the item 21 to acquire at least the identification information out of the identification information and the item information. The reading device 40d can be a known reading device (e.g., a code reader that reads one-dimensional codes and two-dimensional codes). When the identification code 22 is a wireless tag, the storage 40 can be provided with a wireless device capable of wireless communication with the wireless tag.

[0027] The storage section 42 stores the article 21. The storage section 42 may take various forms as long as it can store the article 21. For example, when the storage section 42 stores the reel 21a, the storage section 42 may include a storage unit 42u including a main body section 42a and a partition member 42b, as shown in FIG. 3C. The main body section 42a is formed in a U-shape when viewed in the vertical direction (Z-axis direction). The partition member 42b is provided so as to protrude upward at a predetermined angle relative to the main body section 42a, and can store the reel 21a. The angle of the partition member 42b is set so as to prevent the reel 21a from falling off.

[0028] In addition, the storage unit 42u is provided with multiple pairs of partition members 42b, and can store multiple reels 21a. Each of the multiple pairs of partition members 42b is provided with two partition members 42b spaced apart from each other so as not to interfere with the transfer device 40b. In FIG. 3C, for convenience of illustration, some of the members are given reference numbers, but not all of the members are given reference numbers.

[0029] 3B and 3C, the storage units 42u of this embodiment are arranged in an elliptical shape when viewed in the vertical direction (Z-axis direction). The storage section 42 of this embodiment includes two types of storage units 42u, a first storage section 42t1 and a second storage section 42t2, and each storage unit 42u includes a plurality of first storage sections 42t1 or a plurality of second storage sections 42t2 arranged along the vertical direction (Z-axis direction).

[0030] The first storage section 42t1 can store at least one type of item 21 among a plurality of types of items 21 with different external dimensions used in the substrate-related operating machine 10. The second storage section 42t2 can store at least one type of item 21 with an external dimension equal to or larger than that of the item 21 (item 21 that can be stored in the first storage section 42t1), and is formed larger than the first storage section 42t1. For example, as shown in FIG. 3C, the second storage section 42t2 is formed larger in width and depth than the first storage section 42t1. The height dimension of the second storage section 42t2 is formed to be the same as that of the first storage section 42t1.

[0031] For example, if the article 21 is a reel 21a, the first storage section 42t1 can store a reel 21a with a predetermined reel diameter (at least one type of reel 21a). The second storage section 42t2 can store a reel 21a with a predetermined reel diameter and a reel 21a with a larger diameter than the reel 21a (at least one type of reel 21a with an outer dimension equal to or larger than the reel 21a that can be stored in the first storage section 42t1).

[0032] The storage units 42u are connected by a connecting portion 42j. The type, number and arrangement of the storage units 42u can be changed as appropriate. The shape and size (width, depth and height) of the storage units 42u can be set to match the items 21 to be stored, and the storage section 42 can store items 21 other than the reels 21a, such as the component trays 21b. The items 21 may be stored in any suitable storage unit 42u, and when the board production facility 80 includes multiple storage cabinets 40, the items 21 may be stored in any storage cabinet 40 that includes a suitable storage unit 42u.

[0033] The control device 40a includes a known arithmetic device and storage device, and a control circuit is configured. The control device 40a is provided so as to be able to communicate with the transfer device 40b, the reading device 40d, and the display device 40e, and can control them. The storage 40 includes a storage device 53m that stores item information on the item 21, and can also notify the management device 19 of the item information. For example, if the item 21 is a reel 21a, the item information can include the type of parts contained in the reel 21a, the number of parts (remaining number), the reel diameter, the reel thickness, the model and supplier (vendor), the humidity control level, the expiration date, and the like.

[0034] The transfer device 40b stores the item 21 that has entered the warehouse 40 in the storage section 42, and when retrieving the item 21, moves the item 21 stored in the storage section 42 from the storage section 42. Specifically, the transfer device 40b moves the item 21 that has been placed on the placement section 40c during the retrieval work of the item 21 to the storage section 42 and stores it there. In addition, when retrieving the item 21, the transfer device 40b moves the item 21 stored in the storage section 42 to the placement section 40c. This makes it possible to perform the retrieval work of the item 21.

[0035] As shown in FIG. 3B and FIG. 3C, the transfer device 40b of this embodiment is provided inside the storage unit 42u (first storage section 42t1 and second storage section 42t2) when viewed in the vertical direction (Z-axis direction). The transfer device 40b may take various forms as long as it can move the item 21. For example, a robot arm (multi-joint robot), a lifting and sliding mechanism, etc. may be used as the transfer device 40b. As shown in FIG. 3C, the transfer device 40b of this embodiment includes a lifting section 40b1 and a gripping section 40b2.

[0036] The lifting section 40b1 can rotate about an axis along the vertical direction (Z-axis direction) and can lift and lower the gripping section 40b2 along the vertical direction (Z-axis direction). The gripping section 40b2 can grip the article 21 and can move forward or backward at the same angle as the inclination angle of the placement section 40c. In addition, the gripping section 40b2 can move forward or backward at the same angle as the inclination angle of the partition member 42b of the storage section 42.

[0037] Specifically, as shown in Fig. 3C, the gripping unit 40b2 includes a pair of grippers GP1 and GP2. The pair of grippers GP1 and GP2 can grip the article 21 from a direction inclined at a predetermined angle with respect to the vertical direction (Z-axis direction). In this embodiment, the predetermined angle is set to the same angle as the inclination angle of the placement unit 40c and the inclination angle of the partition member 42b of the storage unit 42.

[0038] The pair of grippers GP1, GP2 grip the item 21 by the upper gripper GP1 and the lower gripper GP2 moving in a direction toward each other. Conversely, the pair of grippers GP1, GP2 release their grip on the item 21 by the upper gripper GP1 and the lower gripper GP2 moving in a direction away from each other. The lower gripper GP2 is connected to the lifting / lowering unit 40b1. Therefore, the pair of grippers GP1, GP2 can rotate around an axis along the vertical direction (Z-axis direction) together with the lifting / lowering unit 40b1, and can be raised and lowered along the vertical direction (Z-axis direction) together with the lifting / lowering unit 40b1.

[0039] In this manner, in the storage 40 of this embodiment, the inclination angle of the placement section 40c and the inclination angle of the partition member 42b of the storage section 42 match. Therefore, in the storage 40 of this embodiment, the entry removal operation of removing the article 21 from the placement section 40c and the entry storage operation of storing the removed article 21 in the storage section 42 can be performed by the lifting and lowering motions, the turning motion, the forward motion, and the backward motions of the transfer device 40b. In addition, in the storage 40 of this embodiment, the exit removal operation of removing the article 21 from the storage section 42 and the exit sending operation of sending the removed article 21 to the placement section 40c can be performed by the lifting and lowering motions, the turning motion, the forward motion, and the backward motions of the transfer device 40b.

[0040] The display device 40e may be a known display device, and displays various data so that the worker can visually confirm them. The display device 40e displays, for example, item information about the items 21 stored in the storage unit 42 in response to the worker's operation. The display device 40e of this embodiment is configured with a touch panel, and also functions as an input device that accepts various operations by the worker.

[0041] The control device 40a can also store the position information, entry / exit information, and storage information of the item 21 in the storage section 42 in the storage device 53m, and the display device 40e can also display these pieces of information. The position information includes information indicating the storage location of the item 21. The entry / exit information includes information indicating the entry date and time, the exit date and time, and the number of entry / exit times of the item 21. The storage information includes information on at least the humidity of the ambient temperature and humidity of the storage section 42. The control device 40a stores the position information and entry date and time of the item 21 in the storage device 53m when the item 21 is stored. The control device 40a stores the storage information in the storage device 53m while the item 21 is stored. The control device 40a stores the exit date and time of the item 21 in the storage device 53m when the item 21 is exited, and adds one entry / exit time to the number of entry / exit times and stores it in the storage device 53m.

[0042] 1-4. Goods storage device 50 As described above, the storage section 42 includes two types of storage units 42u, the first storage section 42t1 and the second storage section 42t2, and the repository 40 includes both the first storage section 42t1 and the second storage section 42t2. The second storage section 42t2 can store an item 21 that is equal to or larger than the outer dimensions of the item 21 that can be stored in the first storage section 42t1, and is formed larger than the first storage section 42t1, so that the item 21 that can be stored in the first storage section 42t1 can also be stored in the second storage section 42t2.

[0043] Therefore, if there is no free space in the storage area of ​​the first storage section 42t1, the items 21 that can be stored in the first storage section 42t1 may be stored in the second storage section 42t2. As a result, the storage area of ​​the second storage section 42t2 may be insufficient. Also, there may be a surplus in the storage area of ​​the first storage section 42t1. In this way, the worse the storage condition of the items 21 becomes, the lower the storage efficiency of the storage cabinet 40 for the items 21 may become.

[0044] Therefore, the board production equipment 80 of this embodiment is provided with an item storage device 50. The item storage device 50 includes a storage 40 and a placement unit 51. The storage 40 may take various forms as long as it includes both the first storage unit 42t1 and the second storage unit 42t2. The item storage device 50 may also include a movement unit 52. The item storage device 50 may also include a memory unit 53 and an initial placement unit 54. The placement unit 51, the movement unit 52, the memory unit 53, and the initial placement unit 54 may be provided in various control devices.

[0045] For example, at least some of the arrangement unit 51, the movement unit 52, the memory unit 53, and the initial arrangement unit 54 can be provided in the control device 40a of the storage 40. At least some of the arrangement unit 51, the movement unit 52, the memory unit 53, and the initial arrangement unit 54 can also be provided in the management device 19. At least some of the arrangement unit 51, the movement unit 52, the memory unit 53, and the initial arrangement unit 54 can also be formed on the cloud. The item storage device 50 of this embodiment includes the arrangement unit 51, the movement unit 52, the memory unit 53, and the initial arrangement unit 54. Also, as shown in FIG. 4, the arrangement unit 51, the movement unit 52, the memory unit 53, and the initial arrangement unit 54 are provided in the control device 40a of the storage 40.

[0046] Further, the item storage device 50 of this embodiment executes control according to the flowchart shown in Fig. 5. The placement unit 51 performs the judgment shown in step S15 and the process shown in step S16. The movement unit 52 performs the judgment shown in step S13 and the process shown in step S14. The memory unit 53 performs the process shown in step S11. The initial placement unit 54 performs the process shown in step S12. As will be described later, the control regarding the movement of the items 21 or the partition member 42b by the item storage device 50 is performed during a specified time period, and is executed independently of the control regarding the normal entry and exit of the items 21 as described above.

[0047] 1-4-1. Arrangement section 51 The placement unit 51 moves the items 21 stored between the first storage unit 42t1 and the second storage unit 42t2 when it is necessary to improve the storage state of the storage cabinet 40 (steps S15 and S16 shown in FIG. 5). The placement unit 51 may take various forms as long as it is capable of moving the items 21 as described above.

[0048] As described above, when there is no free space in the storage area of ​​the first storage section 42t1, the items 21 that can be stored in the first storage section 42t1 may be stored in the second storage section 42t2, and the storage efficiency of the items 21 in the storage cabinet 40 may decrease. The arrangement section 51 can determine that it is necessary to improve the storage state of the storage cabinet 40 when the storage rate of the items 21 in the first storage section 42t1 or the storage rate of the items 21 in the second storage section 42t2 exceeds a preset allowable range. In addition, the arrangement section 51 can determine that it is necessary to improve the storage state of the storage cabinet 40 when there is no free space in the storage area of ​​the first storage section 42t1 and the quantity or ratio of the items 21 stored in the second storage section 42t2 exceeds a preset threshold value. When the items 21 that can be stored in the first storage section 42t1 are stored in the second storage section 42t2 and free space occurs in the first storage section 42t1, the arrangement section 51 can move the items 21 stored in the second storage section 42t2 to the first storage section 42t1.

[0049] Specifically, the placement unit 51 determines whether or not it is necessary to improve the storage state of the storage facility 40 (Step S15). If it is necessary to improve the storage state of the storage facility 40 (Yes in Step S15), the placement unit 51 uses the transfer device 40b to move the items 21 that are stored in the second storage unit 42t2 and can be stored in the first storage unit 42t1 to an empty first storage unit 42t1 (Step S16).

[0050] For example, as shown in FIG. 3C, the second storage section 42t2 of the storage 40 of this embodiment is formed with a width dimension and a depth dimension larger than those of the first storage section 42t1. The height dimension of the second storage section 42t2 is formed to be the same as that of the first storage section 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 section 42t2 can store the reel 21a with a predetermined reel diameter and the reel 21a with a diameter larger than that of the reel 21a. In the above embodiment, the arrangement section 51 can use the transfer device 40b to move the reel 21a with a predetermined reel diameter that can be stored in the first storage section 42t1 stored in the second storage section 42t2 to the empty first storage section 42t1.

[0051] If the item 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 item storage device 50 is temporarily terminated without performing the process shown in step S16. Similarly, if the item 21 that can be stored in the first storage section 42t1 is stored in the second storage section 42t2 but there is no free storage space in the first storage section 42t1 that can store the item 21 (No in step S15), the control by the item storage device 50 is temporarily terminated without performing the process shown in step S16.

[0052] As described above, the second storage section 42t2 of the storage cabinet 40 of this embodiment is formed to have a larger width and depth than the first storage section 42t1. In addition, the height of the second storage section 42t2 is formed to be the same as that of the first storage section 42t1. However, the height of the second storage section 42t2 may be formed to be larger than that of the first storage section 42t1. In this case, the width and depth of the second storage section 42t2 may be the same as that of the first storage section 42t1, or may be formed to be larger than that of the first storage section 42t1.

[0053] In a configuration in which the height dimension of the second storage section 42t2 is formed larger than that of the first storage section 42t1, for example, when the article 21 is a reel 21a, the first storage section 42t1 can store the reel 21a having a predetermined thickness t0. The second storage section 42t2 can store the reel 21a having a predetermined thickness t0 and the reel 21a having a thickness t0 thicker than that of the reel 21a. In this configuration, the arrangement section 51 can use the transfer device 40b to move the reel 21a having the predetermined thickness t0 that can be stored in the first storage section 42t1, which is stored in the second storage section 42t2, to an empty first storage section 42t1.

[0054] Furthermore, the placement section 51 can move the item 21 that can be stored in the first storage section 42t1 and that is stored in the second storage section 42t2 to any available first storage section 42t1. For example, the placement section 51 can move the item 21 that can be stored in the first storage section 42t1 and that is stored in the second storage section 42t2 so that the item 21 is stored from the first storage section 42t1 that is closer to the loading / unloading section 41 of the storage 40. This can shorten the travel distance traveled by the transfer device 40b when unloading the item 21, and can shorten the time required for unloading the item 21 (the time required from an unloading request until the item 21 can be unloaded).

[0055] As shown in Fig. 3C, in the storage 40 of this embodiment, each storage unit 42u has a plurality of first storage sections 42t1 or a plurality of second storage sections 42t2 arranged along the vertical direction (Z-axis direction). Also, as shown in Fig. 3A, the opening 41a and the placement section 40c of the loading / unloading section 41 are provided in the center of the storage 40 in the vertical direction (Z-axis direction). Furthermore, the transfer device 40b is provided inside the storage unit 42u (the first storage sections 42t1 and the second storage sections 42t2) when viewed in the vertical direction (Z-axis direction).

[0056] Therefore, the arrangement section 51 can move the article 21 that can be stored in the first storage section 42t1 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). The arrangement section 51 can also move the article 21 that can be stored in the first storage section 42t1 stored in the second storage section 42t2, starting from the empty first storage section 42t1 of the storage unit 42u that has the shortest distance to the placement section 40c. The arrangement section 51 can also move the article 21 that can be stored in the first storage section 42t1 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) of the storage unit 42u that has the shortest distance to the placement section 40c.

[0057] In this way, the article storage apparatus 50 can shorten the distance traveled by the transfer device 40b when retrieving the article 21, and can shorten the time required to retrieve the article 21. Therefore, the article storage apparatus 50 can improve the storage efficiency of the article 21 in the storage facility 40 while shortening the time required to retrieve the article 21.

[0058] The control device 40a of the storage 40 is also connected to the management device 19 shown in FIG. 1 so as to be able to communicate with it. For example, the management device 19 notifies the control device 40a of the occurrence of a changeover in the substrate-related work line 10L. The management device 19 can also notify the control device 40a of the occurrence of a shortage of the items 21 to be supplied to the substrate-related work line 10L. The management device 19 can also notify the control device 40a of the possibility of a changeover occurring within a predetermined period. The management device 19 can also notify the control device 40a of the possibility of a shortage of the items 21 within a predetermined period. The control device 40a can also cause the necessary items 21 to be removed from the warehouse based on these notifications.

[0059] In the above embodiment, the placement unit 51 can also move the items 21 stored in the second storage unit 42t2 and capable of being stored in the first storage unit 42t1 so that the items 21 to be delivered during a changeover are stored and consolidated in the adjacent first storage units 42t1. The placement unit 51 can also move the items 21 stored in the second storage unit 42t2 and capable of being stored in the first storage unit 42t1 so that the items 21 to be delivered during a shortage of the items 21 to be supplied to the substrate-related work line 10L are stored and consolidated in the adjacent first storage units 42t1. The placement unit 51 can also move the items 21 stored in the second storage unit 42t2 and capable of being stored in the first storage unit 42t1 so that the items 21 to be delivered during a possibility of a changeover or a possibility of a shortage of the items 21 to be supplied to the substrate-related work line 10L are stored and consolidated in the adjacent first storage units 42t1.

[0060] The placement section 51 can also move the items 21 stored in the second storage section 42t2 and capable of being stored in the first storage section 42t1 so that the items 21 to be delivered for each substrate-related operation line 10L are stored and consolidated in the adjacent first storage sections 42t1. The placement section 51 can also move the items 21 stored in the second storage section 42t2 and capable of being stored in the first storage section 42t1 so that the items 21 to be delivered for each substrate-related operation machine 10 are stored and consolidated in the adjacent first storage sections 42t1.

[0061] 1-4-2. Moving part 52 As the storage unit 40 is used, the items 21 desired to be stored may change, and the size (width, depth, and height) of the first storage unit 42t1 required for the storage unit 40 may change. Similarly, as the storage unit 40 is used, the items 21 desired to be stored may change, and the size of the second storage unit 42t2 required for the storage unit 40 may change.

[0062] As shown in Fig. 3C, the storage cabinet 40 of this embodiment includes a plurality of first storage sections 42t1 partitioned by a partition member 42b, and a plurality of second storage sections 42t2 partitioned by a partition member 42b. In this embodiment, it is easier to increase or decrease the height dimension of the first storage section 42t1 than to increase or decrease the width dimension or depth dimension of the first storage section 42t1. Similarly, it is easier to increase or decrease the height dimension of the second storage section 42t2 than to increase or decrease the width dimension or depth dimension of the second storage section 42t2.

[0063] Therefore, the item storage device 50 of this embodiment includes a moving unit 52. The moving unit 52 moves the partition member 42b so as to increase the number of first storage units 42t1 or second storage units 42t2 capable of storing items 21 that have been stored in and removed from the storage 40 a predetermined number of times or more. As described above, the control device 40a adds the number of times of storage and removal once when the item 21 is removed from the storage device 53m, and stores the increment in the storage device 53m. Thus, the moving unit 52 can obtain information on the items 21 that have been stored in and removed from the storage device 53m a predetermined number of times or more, and the number and thickness of the items 21.

[0064] Then, the movement unit 52 judges whether or not movement of the partition member 42b is necessary (step S13 shown in FIG. 5). For example, when the necessary number of first storage units 42t1 or second storage units 42t2 capable of storing the items 21 having been entered and removed a predetermined number of times or more are not secured in the storage 40, the movement unit 52 can judge that movement of the partition member 42b is necessary. Conversely, when the necessary number of first storage units 42t1 and second storage units 42t2 capable of storing the items 21 having been entered and removed a predetermined number of times or more are secured in the storage 40, the movement unit 52 can judge that movement of the partition member 42b is unnecessary.

[0065] If the partition member 42b needs to be moved (Yes in step S13), the moving unit 52 moves the partition member 42b to match the height dimension of the first storage section 42t1 or the second storage section 42t2 to be increased (step S14). As described above, the moving unit 52 may take various forms as long as it can move the partition member 42b. For example, the storage unit 42u has slits formed at regular intervals, 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 adjacent partition members 42b matches the height dimension of the first storage section 42t1 or the second storage section 42t2 to be increased.

[0066] The storage unit 42u may also include a lifting mechanism capable of moving each of the partition members 42b in the vertical direction (Z-axis direction). In this embodiment, the movement section 52 uses the lifting mechanism to move the partition members 42b so that the distance between adjacent partition members 42b matches the height dimension of the first storage section 42t1 or the second storage section 42t2 to be increased. If movement of the partition members 42b is not required (No in step S13), the control by the item storage device 50 proceeds to the judgment in step S15 without performing the process in step S14.

[0067] For example, as shown in FIG. 2B , a component tape 21a2 that stores components to be mounted on a board 90 is wound around the reel 21a. The thickness t0 of the reel 21a varies depending on the width of the component tape 21a2. Therefore, the height of the first storage section 42t1 or the second storage section 42t2 required for the storage 40 is likely to vary as the storage 40 is used. Therefore, when the item 21 is a reel 21a, it is preferable that the moving section 52 moves the partition member 42b in accordance with the thickness t0 of the reel 21a that has been inserted and removed a predetermined number of times or more. This enables the item storage device 50 to increase the number of first storage sections 42t1 or second storage sections 42t2 that can store the reels 21a that have been inserted and removed from the storage 40 a predetermined number of times or more.

[0068] 1-4-3. Memory unit 53 and initial placement unit 54 As described above, the closer the storage area is to the loading / unloading section 41 of the storehouse 40, the shorter the travel distance traveled by the transfer device 40b when unloading the item 21, and the shorter the time required for unloading the item 21. The above matters are not limited to the above-mentioned embodiment. Therefore, in order to take the above matters into consideration when determining the initial storage area of ​​the item 21 in the storage section 42, the item storage device 50 of this embodiment is provided with a memory section 53 and an initial placement section 54.

[0069] The memory unit 53 stores the number of times that the item 21 has entered and exited the storage 40 in the memory device 53m (step S11 shown in FIG. 5). As described above, for example, the memory unit 53 adds one entry / exit count when the item 21 is emptied and stores the count in the memory device 53m. The memory device 53m stores the number of entries / exits for each type of item 21. Based on the number of entries / exits stored in the memory device 53m, the initial placement unit 54 stores the item 21 with a greater number of entries / exits in a storage area closer to the entry / exit section 41 of the storage 40 (step S12).

[0070] The initial placement section 54 can store the item 21 with a higher number of times of entry and exit in a storage area closer to the entry / exit section 41 of the storage 40 in the same manner as in the previously described embodiment. Specifically, the initial placement section 54 can store the item 21 with a higher number of times of entry and exit in a storage area closer to the center of the storage unit 42u in the vertical direction (Z-axis direction). The initial placement section 54 can also store the item 21 with a higher number of times of entry and exit in a storage area of ​​the storage unit 42u with a shorter distance to the placement section 40c. The initial placement section 54 can also store the item 21 with a higher number of times of entry and exit in a storage area closer to the center of the storage unit 42u in the vertical direction (Z-axis direction) with a shorter distance to the placement section 40c.

[0071] The initial placement unit 54 can determine the storage area for the items 21 after a sufficient number of items 21 have entered and left the storage facility 40 to enable statistical analysis. Therefore, when starting operation of a new storage facility 40, the initial placement unit 54 can determine the storage area for the items 21 based on the number of times the items 21 have entered and left the storage facility 40, which is stored in the memory device 53m for the storage facility 40 that is already in operation. It is preferable that the storage facility 40 that is already in operation is a storage facility 40 that is capable of storing items 21 equivalent to the items 21 to be stored in the storage facility 40 that is about to start operation.

[0072] In a configuration in which the article storage device 50 includes the memory unit 53 and the initial placement unit 54, the placement unit 51 may take the following form. For example, the placement unit 51 tally up the number of times of entry and exit stored in the memory unit 53m for each predetermined period, and can move an article 21 with a larger increase in the number of times of entry and exit or a larger increase rate compared to the previous tally to a storage area closer to the entry / exit unit 41 compared to the storage area determined by the initial placement unit 54. The predetermined period can be set arbitrarily, for example, to one week, one month, or the like.

[0073] In the present embodiment, when an item 21 that can be stored in the first storage section 42t1 is stored in the second storage section 42t2 and an empty space occurs in the first storage section 42t1, the arranging section 51 moves the item 21 stored in the second storage section 42t2 to the first storage section 42t1. In this embodiment, the arranging section 51 can move an item 21 with a larger increase in the number of times that it is stored in and out of storage or an increase rate of the number of times that it is stored in and out of storage compared to the past tally (for example, the previous tally) to a storage area (first storage section 42t1) that is closer to the storage area determined by the initial arranging section 54.

[0074] Furthermore, the placement unit 51 can also move the item 21 when the time required for retrieving the item 21 is reduced by a predetermined time or more by changing the storage area from the storage area determined by the initial placement unit 54. This allows the item storage device 50 to move the item 21 when a predetermined effect can be obtained by changing the storage area, thereby reducing the number of times the item 21 is moved.

[0075] The placement unit 51 can also move the item 21 when the time required for the item 21 to be removed from the warehouse becomes equal to or exceeds a specified time. This allows the item storage device 50 to move the item 21 when a change in storage area is required, thereby reducing the number of times the item 21 is moved. Note that the thresholds for determining whether or not to move the item 21 (the above-mentioned predetermined time and specified time) can be set arbitrarily, and can be derived in advance by simulation, verification using an actual machine, or the like.

[0076] The placement unit 51 can also move the item 21 during a time period designated by a user or during a time period when the number of times the item 21 is stored and retrieved is expected to be equal to or less than a specified number. This allows the item storage device 50 to reduce the impact on normal storing and retrieving of the item 21 using the transfer device 40b.

[0077] For example, the user can use a touch panel (the display device 40e functioning as an input device) to specify any time period during which the item 21 is to be moved. Also, for example, a time period during which there is less changeover work and less in- and out-of-stocking of the item 21 compared to the daytime, such as at night, is included in the time period during which the number of in- and out-stocking of the item 21 is expected to be equal to or less than the specified number. Note that the above-mentioned specified number can be set arbitrarily and can be derived in advance by simulation, verification using an actual machine, or the like.

[0078] 2. Variations The storage 40 in the modified form includes a tray storage section 42t3 capable of storing a tray 60. Furthermore, when it is necessary to improve the storage state of the storage 40, the arrangement section 51 in the modified form moves the stored articles 21 between target trays 60t that are trays 60 storing fewer articles 21 than the maximum number of storable articles 21. In the modified form, the differences from the embodiment are mainly described, and overlapping descriptions are omitted.

[0079] 2-1.Tray 60 The tray 60 stores the article 21 used in the substrate-related operating machine 10 that performs a predetermined substrate-related operation on the substrate 90. The tray 60 may have various forms as long as it can store the article 21. The tray 60 may include a first storage section 61 capable of storing at least one type of article 21 (in the case of the reel 21a, referred to as the first reel 21f in this specification) among a plurality of types of articles 21 having different outer dimensions. The tray 60 may also include a second storage section 62 capable of storing 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 an outer dimension equal to or larger than that of the article 21 (article 21 that can be stored in the first storage section 61) and which is larger than the first storage section 61. The tray 60 may also include both the first storage section 61 and the second storage section 62.

[0080] 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 can also include a pin member 63. The tray 60 can also include cutout portions 64, 64. As shown in Fig. 7, the tray 60 includes a first storage section 61, a second storage section 62, a pin member 63, and cutout portions 64, 64. The first storage section 61 and the second storage section 62 can take various forms. The second storage section 62 shown in Fig. 7 is provided above the first storage section 61 in the vertical direction (Z-axis direction) and continuous with the storage space of the first storage section 61. The first storage section 61 is formed with a first recess 61a capable of accommodating the first reel 21f. The second storage section 62 is formed with a second recess 62a capable of accommodating the second reel 21s.

[0081] Since the reel 21a is cylindrical, the first recess 61a is formed as a cylindrical recess (roughly the shape excluding the notches 64, 64 described later) having a diameter slightly larger than the outer diameter of the first reel 21f. The second recess 62a is formed as a cylindrical recess having a diameter slightly larger than the outer diameter of the second reel 21s. Since the second storage section 62 is provided above the first storage section 61 in the vertical direction (Z-axis direction) so as to be continuous with the storage space of the first storage section 61, the bottom surface 61b of the first recess 61a and the bottom surface 62b of the second recess 62a are formed in a stepped shape.

[0082] The tray 60 can include at least one first storage section 61 and at least one second storage section 62. The tray 60 shown in Fig. 7 includes a plurality of (four in the figure) first storage sections 61 and one second storage section 62. The tray 60 includes a main body section 60a that is square (roughly shaped excluding cutout sections 64, 64 described later) when viewed in the vertical direction (Z-axis direction), and the plurality of (four) first storage sections 61 and one second storage section 62 are formed in the main body section 60a.

[0083] At least one first reel 21f can be accommodated in one first storage section 61. At least one second reel 21s can be accommodated in one second storage section 62. As the number of first reels 21f accommodated in one first storage section 61 increases, the operation of removing the first reels 21f accommodated in the first storage section 61 becomes more complicated. As the number of first reels 21f accommodated in one first storage section 61 increases, the management of the first reels 21f becomes more complicated. The same applies to the second reel 21s accommodated in the second storage section 62.

[0084] 8, it is preferable that each of the multiple (four) first storage sections 61 has a height dimension H1 set so as to be able to store one first reel 21f, and that one second storage section 62 has a height dimension H2 set so as to be able to store one second reel 21s. It is also preferable that one tray 60 stores either the first reel 21f or the second reel 21s. This makes it easier to take out the desired reel 21a from the tray 60, and makes it easier to manage the reels 21a.

[0085] As shown in Fig. 8, the first storage section 61 and the second storage section 62 can store the reel 21a such that the axial direction (direction of the arrow R) of the rotation axis R0 of the reel 21a coincides with the vertical direction (Z-axis direction). Also, as shown in Fig. 6, the first storage section 61 is arranged such that the rotation axis R0 of the first reel 21f stored in the first storage section 61 is located on the same circumference (on a circle CL0) centered on the rotation axis R0 of the second reel 21s stored in the second storage section 62 when viewed in the vertical direction (Z-axis direction). As a result, the tray 60 can efficiently store a plurality of types of reels 21a having different outer dimensions (reel diameters) in the vertical direction (Z-axis direction).

[0086] Furthermore, even if the reels 21a have the same outer dimensions (reel diameter), the width dimension of the component tape 21a2 may differ, and the height dimension (thickness t0) of the reels 21a may differ. For example, if the height dimension of the first storage section 61 is set to match the maximum height dimension (thickness t0) of the first reel 21f to be used, gaps are likely to occur in the first storage section 61. The same applies to the height dimension of the second storage section 62. Therefore, it is preferable that the height dimension of at least one of the first storage section 61 and the second storage section 62 is set to match the minimum height dimension RH0 (minimum thickness t0) of the article 21 (reel 21a). This makes it easier to reduce gaps in the tray 60, improving the storage efficiency of the tray 60.

[0087] The first storage section 61 shown in FIG. 8 has a height H1 set according to the minimum height RH0 (minimum height RH1) of the first reel 21f. The second storage section 62 has a height H2 set according to the minimum height RH0 (minimum height RH2) of the second reel 21s. If the height (thickness t0) of the first reel 21f stored in the first storage section 61 is greater than the minimum height RH1, the first reel 21f encroaches on at least the second storage section 62. In this case, the second storage section 62 does not store the second reel 21s. If the height (thickness t0) of the second reel 21s stored in the second storage section 62 is greater than the minimum height RH2, the second reel 21s is stored in a state where it protrudes from the tray 60.

[0088] The first storage section 61 can also store a plurality of types of first reels 21f having different outer dimensions (reel diameters). Similarly, the second storage section 62 can also store a plurality of types of second reels 21s having different outer dimensions (reel diameters). For example, at least one of the first storage section 61 and the second storage section 62 may include a pin member 63. The pin member 63 is inserted into a support hole of the reel 21a when the reel 21a is stored.

[0089] The pin member 63 is formed in a cylindrical shape, and the outer diameter of the pin member 63 is set to be slightly smaller than the outer diameter of the support hole of the reel 21a. The height dimension of the pin member 63 provided in the first storage section 61 is set to be smaller than the height dimension H1 of the first storage section 61. Similarly, the height dimension of the pin member 63 provided in the second storage section 62 is set to be smaller than the height dimension H2 of the second storage section 62. The tray 60 shown in FIG. 7 includes the pin member 63 in the second storage section 62. This allows the second storage section 62 to store a plurality of types of second reels 21s having different outer dimensions (reel diameters).

[0090] The outer dimensions of the first storage section 61 are set so as to be able to accommodate the reel 21a with the smallest outer dimensions (the reel 21a with the smallest reel diameter, referred to herein as the smallest reel) among the reels 21a used in the production of the board products. The outer dimensions of the second storage section 62 are set so as to be able to accommodate the reel 21a with the largest outer dimensions (the reel 21a with the largest reel diameter, referred to herein as the largest reel) among the reels 21a used in the production of the board products. The main body 60a is set to be slightly larger than the outer dimensions of the second storage section 62. Furthermore, the second storage section 62 is provided with a pin member 63.

[0091] Therefore, the outer dimensions of the tray 60 can be set according to the outer dimensions (reel diameter) of the largest reel. Also, for example, the outer dimensions (reel diameter) of the smallest reel are about half of the outer dimensions (reel diameter) of the largest reel. Therefore, in one tray 60, it is easy to evenly arrange a plurality (four) of first storage sections 61, and it is easy to evenly store a plurality (four) of smallest reels. Furthermore, since the second storage section 62 is provided with the pin member 63, the worker can store a plurality of types of second reels 21s whose outer dimensions (reel diameter) are larger than the smallest reel and smaller than the largest reel in the second storage section 62 without worrying about the outer dimensions (reel diameter) of the second reels 21s. As shown in FIG. 6 and FIG. 7, the tray 60 is provided with a specific code 23 that can identify the tray 60. Also, the reel 21a is provided with an identification code 22.

[0092] 2-2. Storage 40 The storage 40 may have various configurations as long as it has a tray storage section 42t3 capable of storing the tray 60 for storing the article 21. The storage 40 has an entry / exit section 41, a storage section 42, a control device 40a, a transfer device 40b, a reading device 40d, and a display device 40e. The entry / exit section 41 has an opening 41a and a placement section 40c. However, as shown in FIG. 9 and FIG. 10, the storage 40 in a modified form is formed, for example, in a dodecagonal prism shape. FIG. 9 is an enlarged view of a part of the storage unit 42u. As shown in the figure, the storage unit 42u has 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.

[0093] Specifically, as shown in Fig. 7 and Fig. 9, a pair of protrusions 60e1, 60e1 protruding in the width direction (arrow TW direction) is formed on both ends 60e, 60e of the tray 60. The protrusions 60e1, 60e1 are inserted into a pair of slits 42d, 42d formed at the same height, and both ends 60e, 60e of the tray 60 are supported. This allows the storage unit 42 to store each of the multiple trays 60 in a predetermined tray storage unit 42t3. The storage unit 42 can store the multiple trays 60 in the vertical direction (Z-axis direction) while minimizing the gap in the vertical direction (Z-axis direction).

[0094] Furthermore, as shown in FIG. 10, the storage section 42 includes a plurality of storage units 42u (six in the figure). Each of the plurality (six) storage units 42u includes a plurality of tray storage sections 42t3 arranged along the vertical direction (Z-axis direction). As shown in the figure, the plurality (six) storage units 42u are arranged in a circle when viewed in the vertical direction (Z-axis direction). In this embodiment, the closer the plurality (six) storage units 42u arranged in a circle are to the center, the higher the possibility of interference with adjacent trays 60 when the tray 60 is stored in the tray storage section 42t3. Therefore, the tray 60 may include cutouts 64, 64 at corners formed in a square or rectangular shape when viewed in the vertical direction (Z-axis direction). The cutouts 64, 64 are formed at the corners on the center side of the plurality (six) storage units 42u arranged in a circle so that the tray 60 does not interfere with adjacent trays 60 when stored in the tray storage section 42t3.

[0095] As shown in FIG. 10, the tray 60 is formed in a square shape when viewed in the vertical direction (Z-axis direction). The cutouts 64, 64 are formed in two corners on the center side of the multiple (six) storage units 42u arranged in a circle among the four corners of the square. The cutouts 64, 64 are formed as if the two corners were cut along the pull-out direction (arrow DW direction) of the adjacent tray 60. That is, an end face of one cutout 64 is provided along the pull-out direction (arrow DW direction) of the adjacent tray 60. An end face of the other cutout 64 is provided along the pull-out direction (arrow DW direction) of the other adjacent tray 60.

[0096] This prevents the tray 60 from interfering with the adjacent tray 60 when the tray 60 is stored in the tray storage section 42t3. The above also applies to the case where the tray 60 is formed in a rectangular shape when viewed in the vertical direction (Z-axis direction). For convenience of illustration, FIG. 10 shows the cutout portions 64, 64 and the pull-out direction (arrow DW direction) of the adjacent tray 60 for one tray 60. The above also applies to the cutout portions 64, 64 of the other trays 60.

[0097] The number and arrangement of the storage units 42u can be changed as appropriate. Similarly, the number of tray storage sections 42t3 in each of the multiple storage units 42u can be changed as appropriate. In addition, the tray storage section 42t3 can be changed as appropriate in terms of the spacing between the pair of support members 42c, 42c and the vertical (Z-axis) pitch of the pair of slits 42d, 42d according to the size (width, depth, and height) of the tray 60 to be stored.

[0098] 2-3. Arrangement section 51 When it is necessary to improve the storage condition of the storage facility 40, the placement unit 51 moves the stored items 21 between target trays 60t, which are trays 60 that contain fewer items 21 than the maximum number of items 21 that can be stored (corresponding to steps S15 and S16 shown in Figure 5).

[0099] As described above, the arrangement unit 51 may take various forms as long as it can move the articles 21. For example, in the tray 60 shown in Figs. 6 to 8, a maximum of four reels 21a (first reels 21f) can be stored in the first storage unit 61 in one tray 60. In this way, when the storage 40 stores a target tray 60t in which fewer articles 21 (reels 21a) are stored than the maximum number of articles 21 (reels 21a) that can be stored (four in this case), the storage efficiency of the articles 21 (reels 21a) in the storage 40 may decrease. The arrangement 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.

[0100] The arrangement unit 51 can move the article 21 (reel 21a) stored in the target tray 60t to another target tray 60t so that an empty tray 60 is generated in which no article 21 (reel 21a) is stored. Specifically, the arrangement unit 51 judges whether or not it is necessary to improve the storage state of the storage 40 (corresponding to step S15 shown in FIG. 5). If it is necessary to improve the storage state of the storage 40 (corresponding to Yes in step S15), the arrangement unit 51 uses the transfer device 40b and the reel transfer device to move the article 21 (reel 21a) stored in the target tray 60t to another target tray 60t (corresponding to step S16).

[0101] For example, the reel transfer device is provided in the placement section 40c. The reel transfer device adsorbs the article 21 (reel 21a) stored in the target tray 60t moved to the placement section 40c by the transfer device 40b, and moves the article 21 (reel 21a) to a waiting location. The reel transfer device stores the article 21 (reel 21a) in another target tray 60t moved to the placement section 40c by the transfer device 40b. The arrangement section 51 repeats the above control to aggregate the article 21 (reel 21a) stored in the target tray 60t to another target tray 60t. This results in an empty tray 60 that does not store the article 21 (reel 21a), and the number of target trays 60t is reduced.

[0102] 9, a plurality of tray storage sections 42t3 are provided along the vertical direction (Z-axis direction) in the storage section 42. Therefore, there is a possibility that the upper end 21t of the article 21 (reel 21a) stored in the tray 60 stored in the tray storage section 42t3 may encroach on another tray storage section 42t3 adjacent in the vertical direction (Z-axis direction).

[0103] For example, at least one of the first storage section 61 and the second storage section 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 stored in a state protruding from the tray 60. Therefore, when the upper end portion 21t of the article 21 (reel 21a) stored in the tray 60 stored in the tray storage section 42t3 encroaches on another tray storage section 42t3 adjacent in the vertical direction (Z-axis direction), the article storage device 50 restricts storage of the tray 60 in the other tray storage section 42t3 adjacent in the vertical direction (Z-axis direction).

[0104] This makes it possible to avoid interference between the upper end 21t of the article 21 (reel 21a) stored in the tray 60 stored in the tray storage section 42t3 and the tray 60 stored in another tray storage section 42t3 adjacent in the vertical direction (Z-axis direction). Note that the article 21 (reel 21a) encroaching on the adjacent tray storage section 42t3 is mainly assumed to be the second reel 21s, but may also be the first reel 21f.

[0105] Here, the tray 60 in which the upper end 21t of the stored article 21 (reel 21a) encroaches on another adjacent tray storage section 42t3 in the vertical direction (Z-axis direction) is defined as the first tray. The tray storage section 42t3 in which the first tray is stored is defined as the first tray storage section. The other tray storage section 42t3 in which the first tray is stored is defined as the second tray storage section. For example, when the first tray is removed and another first tray is stored in the first tray storage section, the restriction on the storage of the tray 60 in the second tray storage section should be continued. On the other hand, when the first tray is removed and a tray 60 in which the upper end 21t of the article 21 (reel 21a) does not encroach on the second tray storage section is stored in the first tray storage section, the restriction on the storage of the tray 60 in the second tray storage section can be released.

[0106] After the first tray is released, it is often uncertain which of the above trays 60 will be stored in the first tray storage section. Therefore, the placement unit 51 may move the tray 60 so that the tray 60 containing the articles 21 (reels 21a) is stored and aggregated in a plurality of tray storage sections 42t3 adjacent in the vertical direction (Z-axis direction). This makes it easier to form a plurality of vacant tray storage sections 42t3 adjacent in the vertical direction (Z-axis direction) including the first tray storage section and the second tray storage section after the first tray is released.

[0107] The modified article storage device 50 may also include a memory unit 53 and an initial placement unit 54 (corresponding to steps S11 and S12 shown in FIG. 5). However, there is a possibility that a plurality of types of articles 21 may be stored in one tray 60. Therefore, the memory unit 53 stores the number of times of entry and exit for each type of article 21 stored in the tray 60. The placement unit 51 also tallies the number of times of entry and exit stored in the storage device 53m for each predetermined period, and can move an article 21 with a larger increase in the number of times of entry and exit or a larger increase rate compared to the previous tally to a storage area closer to the entry and exit unit 41 compared to the storage area determined by the initial placement unit 54.

[0108] The arrangement unit 51 in the modified form moves the articles 21 stored in the target tray 60t to another target tray 60t so as to generate an empty tray 60 that does not store any articles 21. In this form, the arrangement unit 51 can move the articles 21 (the articles 21 stored in the tray 60 from which the target tray 60t has been eliminated) that have a larger increase in the number of times of entry and exit compared to the past tally (for example, the previous tally) to a storage area (tray storage section 42t3) that is closer to the entry / exit section 41 compared to the storage area determined by the initial arrangement unit 54.

[0109] The placement unit 51 can also move the item 21 (the item 21 stored in the tray 60 from which the target tray 60t has been dissolved) when the time required for the item 21 to be removed is reduced by changing the storage area from the storage area determined by the initial placement unit 54, and the reduced time is equal to or greater than a predetermined time. The placement unit 51 can also move the item 21 (the item 21 stored in the tray 60 from which the target tray 60t has been dissolved) when the time required for the item 21 to be removed is equal to or greater than a specified time. The placement unit 51 can also move the item 21 (the item 21 stored in the tray 60 from which the target tray 60t has been dissolved) during a time period designated by the user or during a time period when the number of times the item 21 is expected to be stored and removed is equal to or less than a specified number of times.

[0110] 3.Other In the above-described embodiment, the article 21 is mainly a reel 21a. However, the article 21 may be, for example, the above-described component tray 21b. The tray 60 may also include only the first storage section 61 of the first storage section 61 and the second storage section 62. The tray 60 may also include only the second storage section 62 of the first storage section 61 and the second storage section 62.

[0111] 4. Examples of Effects of the Embodiments and Modifications The article storage device 50 includes a storage cabinet 40 and a placement unit 51. As a result, the article storage device 50 can improve the storage efficiency of the article 21 in the storage cabinet 40. [Explanation of symbols]
