[0007] This specification discloses a reel storage tray including a first storage section and a second storage section. The first storage section is capable of storing a first reel, which is at least one type of reel among a plurality of types of reels having different outside dimensions around which a component tape that stores components to be mounted on a board is wound. The second storage section is capable of storing a second reel, which is at least one type of reel having outside dimensions larger than those of the first reel.

[0008] This specification also discloses a storage including a storage unit and a moving unit. The storage unit includes a storage space for storing the reel storage tray that stores the reel. The moving unit moves the reel storage tray from a storage position to a predetermined storage space when the reel is stored, and moves the reel storage tray stored in the storage space to a predetermined storage position when the reel is removed. Effect of the Invention

[0009] According to the reel storage tray, the first reel can be stored in the first storage section, and the second reel, which has a larger outer dimension than the first reel, can be stored in the second storage section. Therefore, the reel storage tray can store multiple types of reels with different outer dimensions. What has been described above about the reel storage tray can also be said about the storage unit that stores the reel storage tray. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] 1. Embodiment The reel storage tray 30 and the storage 40 of this embodiment are provided in board production equipment 80. As shown in Fig. 1, the board production equipment 80 includes a substrate-related work line 10L, a receiving section 2A, a reel storage tray 30, a storage 40, and an automated guided vehicle 50. In the board production equipment 80 of this embodiment, the reel 20 that arrives at the receiving section 2A is stored in the reel storage tray 30 and transported to the storage 40 by the automated guided vehicle 50. In addition, the reel 20 stored in the storage 40 is stored in the reel storage tray 30 and transported to the component mounting machine 10c by the automated guided vehicle 50.

[0012] 1-1. Substrate work line 10L In the substrate-related work line 10L, a substrate-related work is performed on a substrate 90 by a substrate-related work machine 10. The type and number of substrate-related work machines 10 constituting the substrate-related work line 10L are not limited. 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.

[0013] The multiple (five) substrate-related operation machines 10 are arranged in the following order from the upstream side: a printer 10a, a print inspection machine 10b, a component mounting machine 10c, a reflow furnace 10d, and an appearance inspection machine 10e. A substrate 90 is carried into the printer 10a located at the beginning of the substrate-related operation line 10L. The substrate 90 is then transported downstream by a substrate transport device of the substrate-related operation line 10L, and is removed from the appearance inspection machine 10e located at the end of the substrate-related operation line 10L.

[0014] The printer 10a prints solder paste 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 components on the board 90 on which the solder has been printed by the printer 10a. 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 components on the board 90.

[0015] The component mounting machine 10c is equipped with a component supplying device that supplies components to be mounted on the board 90. For example, the components can be supplied by a feeder equipped with a reel 20 shown in FIG. 2, a tray, or the like. The reel 20 has a component tape 20b that stores the components wound around a main body 20a. The reel 20 is rotatably and detachably provided on the feeder. The leading end of the component tape 20b is pulled out to a component removal section provided on the feeder, and the components are supplied one after another. The reel 20 can supply relatively small components such as chip components. The components are arranged on a tray. The tray can supply relatively large components such as lead components.

[0016] The reflow furnace 10d heats the board 90 on which the components have been mounted by the component mounting machine 10c, melts the solder, and performs soldering. The appearance inspection machine 10e inspects the mounting state of the components mounted by the component mounting machine 10c. Specifically, the appearance inspection machine 10e recognizes whether the components mounted on the board 90 are appropriate, the mounting state of the components (X coordinate, Y coordinate, and mounting angle), and sends the information to the management device 19.

[0017] In this way, the substrate-related work line 10L can sequentially transport the substrates 90 using a plurality (five) of substrate-related work machines 10 and perform production processes including inspection processes to produce substrate products. The number of substrate-related work machines 10 in the substrate-related work line 10L can be appropriately increased or decreased depending on, for example, the type of substrate products to be produced, and the configuration can be appropriately changed. The substrate-related work line 10L can also be equipped with 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.

[0018] 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.

[0019] 1-2. Arrival section 2A and reel storage tray 30 2, the receiving section 2A is provided with at least one reel storage tray 30. The reel storage tray 30 can store a plurality of types of reels 20 with different outside dimensions (reel diameters). As described above, the reel 20 has wound thereon component tape 20b that stores components to be mounted on the board 90.

[0020] As shown in FIG. 3, the reel storage tray 30 includes a first storage section 31 and a second storage section 32. The reel storage tray 30 can include a pin member 33. The reel storage tray 30 can also include cutout portions 34, 34. As shown in the figure, the reel storage tray 30 of this embodiment includes a first storage section 31, a second storage section 32, a pin member 33, and cutout portions 34, 34. The first storage section 31 can store a first reel 21, which is at least one type of reel 20 among a plurality of types of reels 20 having different outside dimensions. The second storage section 32 can store a second reel 22, which is at least one type of reel 20 having outside dimensions larger than the first reel 21.

[0021] The reel storage tray 30 may have various configurations as long as it can store a plurality of types of reels 20 having different outer dimensions (reel diameters). In this embodiment, as shown in Fig. 3, the second storage section 32 is provided above the first storage section 31 in the vertical direction (arrow Z direction) so as to be continuous with the storage space of the first storage section 31. The first storage section 31 is formed with a first recess 31a capable of storing the first reel 21. The second storage section 32 is formed with a second recess 32a capable of storing the second reel 22.

[0022] Since the reel 20 is cylindrical, the first recess 31a is formed as a cylindrical recess (roughly the same shape excluding the notches 34, 34 described later) having a diameter slightly larger than the outer diameter of the first reel 21. The second recess 32a is formed as a cylindrical recess having a diameter slightly larger than the outer diameter of the second reel 22. Since the second storage section 32 is provided above the first storage section 31 in the vertical direction (arrow Z direction) so as to be continuous with the storage space of the first storage section 31, the bottom surface 31b of the first recess 31a and the bottom surface 32b of the second recess 32a are formed in a stepped shape.

[0023] The reel storage tray 30 can include at least one first storage section 31 and at least one second storage section 32. As shown in Fig. 3, the reel storage tray 30 of this embodiment includes a plurality of (four in Fig. 3) first storage sections 31 and one second storage section 32. In addition, the reel storage tray 30 of this embodiment has a main body section 30a that is square (roughly shaped excluding cutout sections 34, 34 described later) when viewed in the vertical direction (arrow Z direction), and the plurality of (four) first storage sections 31 and one second storage section 32 are formed in the main body section 30a.

[0024] At least one first reel 21 can be accommodated in one first storage section 31. At least one second reel 22 can be accommodated in one second storage section 32. As the number of first reels 21 accommodated in one first storage section 31 increases, the operation of removing the first reels 21 accommodated in the first storage section 31 becomes more complicated. As the number of first reels 21 accommodated in one first storage section 31 increases, the management of the first reels 21 becomes more complicated. The same can be said about the second reel 22 accommodated in the second storage section 32.

[0025] 4, it is preferable that each of the plurality (four) of first storage sections 31 has a height dimension H1 set so as to be able to store one first reel 21, and that one second storage section 32 has a height dimension H2 set so as to be able to store one second reel 22. This makes it easier to take out a desired reel 20 from the reel storage tray 30, and makes it easier to manage the reels 20.

[0026] Also, only at least one first reel 21 can be accommodated in one reel storage tray 30. Also, only at least one second reel 22 can be accommodated in one reel storage tray 30. Furthermore, in one reel storage tray 30, at least one first reel 21 can be accommodated in the first storage section 31, and at least one second reel 22 can be accommodated in the second storage section 32. When the ease of removal and management of the reel 20 is emphasized, it is preferable to accommodate either the first reel 21 or the second reel 22 in one reel storage tray 30. In the case where one reel storage tray 30 has a plurality of (four) first storage sections 31 as in this embodiment, one reel storage tray 30 can accommodate one first reel 21 in each of the plurality of (four) first storage sections 31 without accommodating the second reel 22.

[0027] As shown in Fig. 4, in this embodiment, the first storage section 31 and the second storage section 32 can store the reel 20 such that the axial direction (arrow R direction) of the rotation axis R0 of the reel 20 coincides with the vertical direction (arrow Z direction). Also, as shown in Fig. 2, the first storage section 31 is arranged such that the rotation axis R0 of the first reel 21 stored in the first storage section 31 is located on the same circumference (on a circle CL0) centered on the rotation axis R0 of the second reel 22 stored in the second storage section 32 when viewed in the vertical direction (arrow Z direction). As a result, the reel storage tray 30 of this embodiment can efficiently store a plurality of types of reels 20 having different outer dimensions (reel diameters) in the vertical direction (arrow Z direction).

[0028] Furthermore, even if the reels 20 have the same outer dimensions (reel diameter), the width dimension of the component tape 20b may differ, and therefore the height dimension may differ. For example, if the height dimension of the first storage section 31 is set to match the maximum height dimension of the first reel 21 to be used, gaps are likely to occur in the first storage section 31. The same can be said about the height dimension of the second storage section 32. Therefore, it is preferable that the height dimension of at least one of the first storage section 31 and the second storage section 32 is set to match the minimum height dimension RH0 of the reel 20. This makes it easier to reduce gaps in the reel storage tray 30, and improves the storage efficiency of the reel storage tray 30.

[0029] As shown in FIG. 4, in this embodiment, the first storage section 31 has a height H1 set in accordance with the minimum height RH0 (minimum height RH1) of the first reel 21. The second storage section 32 has a height H2 set in accordance with the minimum height RH0 (minimum height RH2) of the second reel 22. If the height of the first reel 21 stored in the first storage section 31 is greater than the minimum height RH1, the first reel 21 encroaches on at least the second storage section 32. In this case, the second storage section 32 does not store the second reel 22. If the height of the second reel 22 stored in the second storage section 32 is greater than the minimum height RH2, the second reel 22 is stored in a state where it protrudes from the reel storage tray 30.

[0030] The first storage section 31 can also store a plurality of types of first reels 21 having different outer dimensions (reel diameters). Similarly, the second storage section 32 can also store a plurality of types of second reels 22 having different outer dimensions (reel diameters). For example, at least one of the first storage section 31 and the second storage section 32 can be provided with a pin member 33. The pin member 33 is inserted into a support hole of the reel 20 when the reel 20 is stored.

[0031] The pin member 33 is formed in a cylindrical shape, and the outer diameter of the pin member 33 is set to be slightly smaller than the outer diameter of the support hole of the reel 20. The height dimension of the pin member 33 provided in the first storage section 31 is set to be smaller than the height dimension H1 of the first storage section 31. Similarly, the height dimension of the pin member 33 provided in the second storage section 32 is set to be smaller than the height dimension H2 of the second storage section 32. As shown in FIG. 3, the reel storage tray 30 of this embodiment includes the pin member 33 in the second storage section 32. This allows the second storage section 32 to store a plurality of types of second reels 22 having different outer dimensions (reel diameters).

[0032] In this embodiment, the outer dimensions of the first storage section 31 are set so as to be able to accommodate the reel 20 with the smallest outer dimensions (the reel 20 with the smallest reel diameter, referred to herein as the smallest reel) among the reels 20 used in the production of the board products. The outer dimensions of the second storage section 32 are set so as to be able to accommodate the reel 20 with the largest outer dimensions (the reel 20 with the largest reel diameter, referred to herein as the largest reel). The main body section 30a is set to be slightly larger than the outer dimensions of the second storage section 32. Furthermore, the second storage section 32 is provided with a pin member 33.

[0033] Therefore, the outer dimensions of the reel storage tray 30 of this embodiment can be set according to the outer dimensions (reel diameter) of the largest reel. Also, the outer dimensions (reel diameter) of the smallest reel of this embodiment is about half of the outer dimensions (reel diameter) of the largest reel. Therefore, in one reel storage tray 30, it is easy to evenly arrange a plurality of (four in this embodiment) first storage sections 31, and it is easy to evenly store a plurality (four) of smallest reels. Furthermore, since the second storage section 32 is provided with the pin member 33, the operator can store a plurality of types of second reels 22 whose outer dimensions (reel diameter) are larger than the smallest reel and smaller than the largest reel in the second storage section 32 without worrying about the outer dimensions (reel diameter) of the second reels 22.

[0034] 2 and 3, the reel storage tray 30 is provided with a tray identification code 23. The tray identification code 23 includes identification information for identifying one reel storage tray 30 from among the multiple reel storage trays 30. The reel 20 is provided with a reel identification code 24. The reel identification code 24 includes identification information for identifying one reel 20 from among the multiple reels 20. The tray identification code 23 and the reel identification code 24 may be, for example, a one-dimensional code, a two-dimensional code, or a wireless tag.

[0035] When the reel 20 arrives at the receiving section 2A, a worker at the receiving section 2A issues a reel identification code 24 including identification information, for example, using a reel management device. The worker also uses a barcode reader or the like to read a barcode or the like attached to the reel 20 by the supplier (vendor). The worker can also obtain the reel information of the reel 20 from a database in which reel information related to the reel 20 is registered. The worker can also use the reel management device to issue a reel identification code 24 including identification information and reel information.

[0036] An operator at the receiving section 2A attaches a reel identification code 24 including at least identification information to the reel 20. When the operator places the reel 20 in the reel storage tray 30, the operator reads the tray identification code 23 attached to the reel storage tray 30 using a reading device. The operator also reads the reel identification code 24 attached to the reel 20 using a reading device, and places the reel 20 in the reel storage tray 30. This creates a correspondence between the identification information that identifies the reel storage tray 30 and the identification information that identifies the reel 20. FIG. 2 shows an example of a state in which the reel 20 is stored in the reel storage tray 30. Note that the figure is a plan view, and shows an example of a storage state of the reel 20 in a schematic manner.

[0037] The worker at the receiving section 2A loads the reel storage tray 30 containing the reel 20 onto the automated guided vehicle 50. The automated guided vehicle 50 is an automated guided vehicle (AGV: Automatic Guided Vehicle) that does not require a worker to operate it. The worker can also transport the reel 20 or the reel storage tray 30 containing the reel 20 without using the automated guided vehicle 50. 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), a reel management device, etc. When the worker transports a reel 20 that is not contained in the reel storage tray 30, the storage 40 stores the reel 20 in the reel storage tray 30.

[0038] The substrate-related work line 10L, the receiving section 2A, the storage 40, the automated guided vehicle 50, and the management device 19 are arranged to be able to communicate with each other via a wired or wireless communication unit. The above-mentioned correspondence is transmitted from the receiving section 2A to the management device 19 via the communication unit. When the reel storage tray 30 is loaded onto the automated guided vehicle 50, the management device 19 transmits a transport command to the automated guided vehicle 50. The transport command includes the transport destination of the reel storage tray 30. When the automated guided vehicle 50 receives the transport command, it transports the reel storage tray 30 to the storage 40 designated as the transport destination.

[0039] 1-3. Storage 40 The storage 40 may take various forms as long as it can store the reel storage trays 30 that store the reels 20. As shown in Figs. 5 and 8, the storage 40 of this embodiment is formed, for example, in a dodecagonal prism shape. For convenience of illustration, the outer wall of the storage 40 shown in Fig. 6 has been removed so that the interior of the storage 40 can be seen. Fig. 7 is an enlarged view of a portion of the storage unit 42u in Fig. 6.

[0040] The storage facility 40 includes a storage unit 42 and a moving unit 44. The storage facility 40 of this embodiment includes an entrance unit 41, a storage unit 42, a delivery unit 43, a control device 40a, a moving device 40b, a display device 40c, and an acquisition device 40d. As shown in FIG. 9, the control device 40a includes a moving unit 44 when considered as a control block. The control device 40a can also include a management unit 45. The moving unit 44 and the management unit 45 can be provided in various control devices and management devices. The moving unit 44 and the management unit 45 can also be formed on the cloud.

[0041] 1-3-1. Storage area 41 and delivery area 43 The receiving section 41 receives the reels 20 or the reel storage trays 30 that store the reels 20. The unloading section 43 unloads the reels 20 or the reel storage trays 30 that store the reels 20. The reel storage trays 30 may have any of the forms already described. The receiving section 41 may have various forms as long as it can receive the reels 20 or the reel storage trays 30. Similarly, the unloading section 43 may have various forms as long as it can unload the reels 20 or the reel storage trays 30.

[0042] As shown in FIG. 5 and FIG. 6, the entrance section 41 and the exit section 43 of this embodiment are formed in the same opening. The opening includes a first opening 40f through which the reel 20 or the reel storage tray 30 enters and leaves the warehouse, and a second opening 40s through which the automated guided vehicle 50 carrying the reel storage tray 30 enters and leaves the warehouse. As shown in the figure, the automated guided vehicle 50 is connected to the second opening 40s. The first opening 40f can also be used to enter and exit the reel 20 that is not stored in the reel storage tray 30. In this case, for example, when the reel 20 enters the warehouse, the worker stores the reel 20 in the reel storage tray 30 that has been sent out to the first opening 40f. When the reel 20 is sent out, the worker takes out the reel 20 from the reel storage tray 30 that has been sent out to the first opening 40f.

[0043] Of the storage unit 41 and the delivery unit 43, at least the storage unit 41 is provided with an acquisition device 40d. The control device 40a uses the acquisition device 40d to recognize the reels 20 and the reel storage trays 30 stored in the storage unit 42. The acquisition device 40d can be a known reading device (for example, a code reader that reads one-dimensional codes and two-dimensional codes, a wireless reader that wirelessly communicates with wireless tags, etc.).

[0044] In this embodiment, the acquisition device 40d reads the tray identification code 23 attached to the reel storage tray 30 when the reel storage tray 30 is stored, and acquires identification information for identifying the reel storage tray 30. Also, the acquisition device 40d reads the reel identification code 24 attached to the reel 20 when the reel storage tray 30 is stored, and acquires identification information for identifying the reel 20. Furthermore, the control device 40a acquires the above-mentioned correspondence from the management device 19. The control device 40a confirms that the correspondence between the identification information for identifying the reel storage tray 30 acquired by the acquisition device 40d and the identification information for identifying the reel 20 matches the correspondence acquired from the management device 19, and stores the correspondence in the storage device.

[0045] The reels 20 stored in the stored reel storage tray 30 can be transferred to another reel storage tray 30 provided in the storage 40. As described above, the reels 20 that are not stored in the reel storage tray 30 can also be stored. In these cases, the acquisition device 40d reads the reel identification code 24 attached to the reel 20 when the reel 20 is stored in the storage unit 42, and acquires the identification information for identifying the reel 20 to be stored in the storage unit 42. The control device 40a stores in the storage device the correspondence between the identification information for identifying the reel storage tray 30 in which the reel 20 is stored and the identification information for identifying the reel 20.

[0046] 1-3-2.Storage section 42 The storage section 42 includes a storage space 42s for storing the reel storage tray 30. The storage section 42 may take various forms as long as it is capable of storing the reel storage tray 30. As shown in Figs. 6 and 7, in this embodiment, the storage section 42 includes a pair of support members 42a, 42a for supporting both ends 30e, 30e of the reel storage tray 30 in the width direction (arrow TW direction). The reel storage tray 30 is inserted into a pair of slits 42b, 42b formed at the same height in the pair of support members 42a, 42a, and both ends 30e, 30e are supported.

[0047] Specifically, as shown in Fig. 3 and Fig. 7, a pair of protrusions 30e1, 30e1 protruding in the width direction (arrow TW direction) is formed on both ends 30e, 30e of the reel storage tray 30. The protrusions 30e1, 30e1 are inserted into a pair of slits 42b, 42b formed at the same height, and the reel storage tray 30 is supported at both ends 30e, 30e. This allows the storage section 42 to store each of the multiple reel storage trays 30 in a predetermined storage space 42s. The storage section 42 can store the multiple reel storage trays 30 in the vertical direction (arrow Z direction) while minimizing the gap in the vertical direction (arrow Z direction).

[0048] 8, the storage section 42 of this embodiment includes a plurality of storage units 42u (six in the figure). Each of the plurality (six) storage units 42u has a plurality of storage spaces 42s arranged along the vertical direction (arrow Z direction). As shown in the figure, the plurality (six) storage units 42u are arranged in a circle when viewed in the vertical direction (arrow Z direction).

[0049] In this embodiment, the closer the multiple (six) storage units 42u arranged in a circle are to the center, the higher the possibility that the reel storage tray 30 will interfere with the adjacent reel storage tray 30 when stored in the storage space 42s. Therefore, the reel storage tray 30 may be provided with cutouts 34, 34 at corners formed in a square or rectangular shape when viewed in the vertical direction (arrow Z direction). The cutouts 34, 34 are formed at the corners on the center side of the multiple (six) storage units 42u arranged in a circle so that the reel storage tray 30 will not interfere with the adjacent reel storage tray 30 when stored in the storage space 42s.

[0050] As shown in FIG. 8, the reel storage tray 30 of this embodiment is formed in a square shape when viewed in the vertical direction (arrow Z direction). The cutouts 34, 34 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 34, 34 are formed as if the two corners were cut along the pull-out direction (arrow DW direction) of the adjacent reel storage tray 30. That is, an end face of one cutout 34 is provided along the pull-out direction (arrow DW direction) of the adjacent reel storage tray 30. An end face of the other cutout 34 is provided along the pull-out direction (arrow DW direction) of the other adjacent reel storage tray 30.

[0051] This suppresses interference with adjacent reel storage trays 30 when storing the reel storage trays 30 in the storage space 42s. The above also applies to the case where the reel storage trays 30 are formed in a rectangular shape when viewed in the vertical direction (arrow Z direction). Note that, for convenience of illustration, FIG. 8 illustrates the cutout portions 34, 34 of one reel storage tray 30 and the pull-out direction (arrow DW direction) of the adjacent reel storage tray 30. The above also applies to the cutout portions 34, 34 of the other reel storage trays 30.

[0052] The number and arrangement of the storage units 42u can be changed as appropriate. Similarly, the number of storage spaces 42s in each of the multiple storage units 42u can be changed as appropriate. In addition, the spacing between the pair of support members 42a, 42a and the pitch in the vertical direction (arrow Z direction) of the pair of slits 42b, 42b of the storage space 42s can be changed as appropriate according to the size (width, depth, and height) of the reel storage tray 30 to be stored.

[0053] Assume that a plurality of types of reels 20 having different external dimensions (reel diameters) that are not accommodated in the reel accommodation tray 30 are directly accommodated in the accommodation section 42. In this case, the accommodation section 42 needs to be provided with a plurality of types of storage spaces 42s that match the external dimensions (reel diameters) of the reels 20. Therefore, before using the storage 40, the user needs to determine the type and required number of storage spaces 42s for each external dimension (reel diameter) of the reels 20. In addition, for example, when a difference occurs between the type and required number of storage spaces 42s determined in advance and the type and required number of storage spaces 42s that are actually required in the production of board products, there is a possibility that unused storage spaces 42s or insufficient storage spaces 42s will occur.

[0054] In this embodiment, the storage section 42 stores the reel storage tray 30 capable of storing a plurality of types of reels 20 having different external dimensions (reel diameters). Therefore, the storage space 42s can be designed according to the external dimensions of the reel storage tray 30 regardless of the external dimensions (reel diameters) of the reels 20. In addition, the above-mentioned advance determination is not necessary, and even if there is a change in the type of reels 20 required for the production of the board products, as long as the number of reels 20 stored is the same, there is little surplus or deficiency in the storage space 42s. In this way, the storage section 42 of this embodiment improves the storage efficiency of the reels 20 and improves convenience compared to a case in which a plurality of types of reels 20 having different external dimensions (reel diameters) that are not stored in the reel storage tray 30 are directly stored in the storage section 42.

[0055] 1-3-3.Moving part 44 The moving unit 44 moves the reel storage tray 30 from the storage position to a predetermined storage space 42s when the reel 20 is stored, and moves the reel storage tray 30 stored in the storage space 42s to a predetermined unloading position when the reel 20 is unloaded. The moving unit 44 can move the reel storage tray 30 using the moving device 40b. The moving device 40b may take various forms as long as it is capable of moving the reel storage tray 30.

[0056] The moving device 40b of this embodiment is provided inside the multiple (six) storage units 42u when viewed in the vertical direction (arrow Z direction). For example, a robot arm (articulated robot), a lifting and sliding mechanism, etc. can be used as the moving device 40b. As shown in FIG. 6, the moving device 40b of this embodiment includes a lifting and lowering unit 40b1 and a gripping unit 40b2.

[0057] The lifting section 40b1 lifts and lowers the gripping section 40b2 in the vertical direction (arrow Z direction) while rotating a predetermined angle around an axis along the vertical direction (arrow Z direction). The gripping section 40b2 can grip the reel storage tray 30, and can move forward or backward while gripping the reel storage tray 30. When storing the reel 20, the lifting section 40b1 lifts and lowers the gripping section 40b2 in the vertical direction (arrow Z direction) so that when the gripping section 40b2 moves forward, the gripping section 40b2 reaches the reel storage tray 30 at the storage position. Next, the gripping section 40b2 moves forward to grip the reel storage tray 30, and moves backward while gripping the reel storage tray 30 (removal work at the time of storage).

[0058] Then, the lifting section 40b1 rotates a predetermined angle to lift the gripping section 40b2 up and down in the vertical direction (arrow Z direction) so that the gripping section 40b2 reaches the storage space 42s of the desired storage unit 42u when the gripping section 40b2 advances. Next, the gripping section 40b2 advances and inserts the reel storage tray 30 into the storage space 42s (in this embodiment, a pair of slits 42b, 42b), releases its grip on the reel storage tray 30, and retreats (storage work at the time of warehousing). The moving section 44 repeats the removal work at the time of warehousing and the storage work at the time of warehousing until all the reels 20 to be stored are stored.

[0059] When the reel 20 is removed from the storage unit 42, the lifting section 40b1 raises and lowers the gripping section 40b2 in the vertical direction (the direction of the arrow Z) so that when the gripping section 40b2 advances, the gripping section 40b2 reaches the reel storage tray 30 stored in the storage space 42s of the desired storage unit 42u. Next, the gripping section 40b2 advances to grip the reel storage tray 30 stored in the storage space 42s (in this embodiment, a pair of slits 42b, 42b), and retreats while still gripping the reel storage tray 30 (removal work at the time of removal from the storage unit).

[0060] Then, the lifting section 40b1 rotates a predetermined angle to raise and lower the gripping section 40b2 in the vertical direction (arrow Z direction) so that the gripping section 40b2 reaches a predetermined unloading position of the unloading section 43 when the gripping section 40b2 advances. Next, the gripping section 40b2 advances to unload the reel storage tray 30 to the unloading position, releases its grip on the reel storage tray 30, and retreats (unloading operation at the time of unloading). The moving section 44 repeats the unloading removal operation and the unloading operation at the time of unloading until all of the unloaded reels 20 have been unloaded.

[0061] In this embodiment, the entry position and the exit position are the first opening 40f or the second opening 40s. When the reel 20 stored in the stored reel storage tray 30 is transferred to another reel storage tray 30 provided in the storage 40, the moving device 40b includes a transfer unit. The transfer unit, for example, adsorbs the reel 20 stored in the stored reel storage tray 30 and transfers the reel 20 to another reel storage tray 30 provided in the storage 40. The above also applies to the case where a reel 20 that is not stored in a reel storage tray 30 is stored.

[0062] When the delivery position is the first opening 40f, for example, the worker takes out the reel 20 or the reel storage tray 30 in which the reel 20 is stored. When the delivery position is the second opening 40s, when the reel storage tray 30 is loaded onto the automated guided vehicle 50, the management device 19 transmits a transport command to the automated guided vehicle 50. When the automated guided vehicle 50 receives the transport command, it transports the reel storage tray 30 to the component mounting machine 10c designated as the transport destination.

[0063] 1-3-4. Management Department 45 6 and 7, in this embodiment, the storage section 42 is provided with a plurality of storage spaces 42s arranged in the vertical direction (arrow Z direction). Therefore, there is a possibility that the upper end 20t of the reel 20 stored in the reel storage tray 30 stored in one storage space 42s may encroach on the storage space 42s adjacent in the vertical direction (arrow Z direction).

[0064] For example, as described above, at least one of the first storage section 31 and the second storage section 32 has a height dimension set in accordance with the minimum height dimension RH0 of the reel 20, and mainly the second reel 22 may be stored in a state where it protrudes from the reel storage tray 30. Therefore, when the upper end portion 20t of the reel 20 stored in the reel storage tray 30 stored in one storage space 42s encroaches on the adjacent storage space 42s in the vertical direction (arrow Z direction), the management section 45 restricts the storage of the reel storage tray 30 in the adjacent storage space 42s.

[0065] This makes it possible to avoid interference between the upper end 20t of the reel 20 housed in the reel housing tray 30 housed in one storage space 42s and the reel housing tray 30 housed in the adjacent storage space 42s in the vertical direction (arrow Z direction). Note that the reel 20 encroaching on the adjacent storage space 42s is mainly assumed to be the second reel 22, but it may also be the first reel 21.

[0066] 1-3-5.Other As shown in FIG. 5, the storage 40 includes a display device 40c. A known display device can be used as the display device 40c, and the display device 40c displays various data so that the worker can visually confirm them. For example, the display device 40c displays reel information about the reels 20 stored in the storage section 42 in response to the worker's operation. The display device 40c in this embodiment is configured with a touch panel, and the display device 40c also functions as an input device that accepts various operations by the worker. For example, the worker can use the touch panel (the display device 40c that functions as an input device) to specify the desired reel 20 to be removed from the storage 40. In this case, the control device 40a uses the moving device 40b to move the reel storage tray 30 that stores the specified reel 20 to the removal position of the removal section 43 and remove the reel 20.

[0067] The control device 40a can also store position information, entry / exit information, and storage information of the reel storage tray 30 that stores the reel 20. The position information indicates the storage location of the reel storage tray 30 that stores the reel 20. The entry / exit information indicates the entry date and time and the exit date and time of the reel 20 or the reel storage tray 30 that stores the reel 20. The storage information includes information on the ambient temperature, humidity, and the like of the storage section 42. The control device 40a stores the position information and the entry date and time when the reel 20 or the reel storage tray 30 that stores the reel 20 is entered. The control device 40a stores the storage information while the reel storage tray 30 is in storage. The control device 40a stores the exit date and time when the reel 20 or the reel storage tray 30 that stores the reel 20 is exited.

[0068] 2. Examples of Effects of the Embodiments According to the reel storage tray 30, the first reel 21 can be stored in the first storage section 31, and the second reel 22, which has a larger outer dimension than the first reel 21, can be stored in the second storage section 32. Therefore, the reel storage tray 30 can store a plurality of types of reels 20 with different outer dimensions. What has been described above about the reel storage tray 30 can also be said about the storage cabinet 40 that stores the reel storage tray 30. [Explanation of symbols]
