  • the worker can also obtain item information from a database in which item information about the item 21 is registered.
  • the automated warehouse 40 may take various forms as long as it is equipped with a storage section 42 capable of storing the items 21 in a state where the items 21 are accommodated on the trays 60, or capable of storing the received items 21 as they are.
  • the automated warehouse 40 uses the transfer device 40b to carry in the trays 60 housing the items 21 or the items 21 to the storage section 42 and store them.
  • the transfer device 40b is used to carry out the trays 60 housing the items 21 or the items 21 from the storage section 42, making it possible to remove the items 21.

As shown in FIG. 3A, an opening 41a is provided at the front of the automated warehouse 40. The opening 41a is formed larger than the items 21 so that the items 21 can be loaded and unloaded.
  • the automated warehouse 40 can also have an unloading port at an opening different from the opening 41a through which the items 21 are loaded.
  • the loading section 40c is provided in the work space near the opening 41a.
  • the loading section 40c can temporarily load the item 21 when the item 21 is stored or removed.

  • the unloading operation of the item 21, which involves removing the item 21 placed on the loading section 40c can be performed by an operator.
  • An imaging device 40d is provided above the loading section 40c. When the item 21 is stored in the automated warehouse 40 through the opening 41a, the imaging device 40d captures an image of the item identification member 22 attached to the item 21, and acquires item identification information that can identify the stored item 21.
  • the storage section 42 can store the item 21 or a tray 60 that stores the item 21.
  • the tray 60 can take various forms as long as it can store the item 21. As shown in Figures 4 and 5, the tray 60 can have a first storage section 61 that can store at least one type of item 21 (in the case of a reel 21a, referred to as the first reel 21f in this specification) among multiple types of items 21 with different external dimensions.
  • the tray 60 can also have a second storage section 62 that can store at least one type of item 21 (in the case of a reel 21a, referred to as the second reel 21s in this specification) that has larger external dimensions than the item 21 that can be stored in the first storage section 61 and is larger than the first storage section 61.
  • the tray 60 can also have both a first storage section 61 and a second storage section 62.
  • the first storage section 61 and the second storage section 62 can take various forms.
  • the second storage section 62 shown in Figure 4 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.
  • the first recess 61a is formed as a cylindrical recess with a diameter slightly larger than the outer diameter of the first reel 21f.
  • the second recess 62a is formed as a cylindrical recess with a diameter slightly larger than the outer diameter of the second reel 21s.
  • the second storage section 62 is provided vertically above the first storage section 61 (Z-axis direction) and continuous with the storage space of the first storage section 61, so that 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.
  • the tray 60 can have at least one first storage section 61 and at least one second storage section 62.
  • the tray 60 shown in FIG. 4 has multiple (four in this figure) first storage sections 61 and one second storage section 62. Also, when viewed in the vertical direction (Z-axis direction), the tray 60 has multiple (four) first storage sections 61 and one second storage section 62 formed in a square main body section 60a.
  • At least one first reel 21f can be stored in one first storage section 61. At least one second reel 21s can be stored in one second storage section 62. The more the number of first reels 21f stored in one first storage section 61 increases, the more complicated the operation of removing the first reels 21f stored in the first storage section 61 becomes. Also, the more the number of first reels 21f stored in one first storage section 61 increases, the more complicated the management of the first reels 21f becomes. The same can be said about the second reel 21s stored in the second storage section 62.
  • each of the multiple (four) first storage sections 61 has a height dimension set so that it can store one first reel 21f
  • one second storage section 62 has a height dimension set so that it can store one second reel 21s.
  • one tray 60 stores either the first reel 21f or the second reel 21s. This makes it easier to remove the desired reel 21a from the tray 60, and makes it easier to manage the reels 21a.
  • first storage section 61 can store multiple types of first reels 21f with different external dimensions (reel diameters).
  • second storage section 62 can store multiple types of second reels 21s with different external dimensions (reel diameters).
  • at least one of the first storage section 61 and the second storage section 62 can be provided with a pin member 63. The pin member 63 is inserted into the support hole of the reel 21a when the reel 21a is stored.
  • 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. Furthermore, the height dimension of the pin member 63 provided in the first storage section 61 is set to be smaller than the height dimension 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 of the second storage section 62.
  • the tray 60 shown in FIG. 4 is provided with a pin member 63 in the second storage section 62. This allows the second storage section 62 to store multiple types of second reels 21s with different outer dimensions (reel diameters).
  • the outer dimensions of the tray 60 can therefore be set to match the outer dimensions (reel diameter) of the largest reel. Also, for example, the outer dimensions (reel diameter) of the smallest reel are approximately half the outer dimensions (reel diameter) of the largest reel. Therefore, it is easy to evenly arrange multiple (four) first storage sections 61 in one tray 60, and to evenly store multiple (four) smallest reels. Furthermore, since the second storage section 62 is provided with a pin member 63, the operator can store multiple 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.
  • the storage unit 42u has a pair of support members 42a, 42a that support side wall portions 60e, 60e at both ends in the width direction (arrow TW direction) of the tray 60.

  • the number and arrangement of the storage units 42u can be changed as appropriate.
  • the number of storage areas 42r in each of the multiple storage units 42u can be changed as appropriate.
  • the spacing between the pair of support members 42a, 42a and the vertical (Z-axis) pitch of the pair of protrusions of the storage area 42r can be changed as appropriate to match the size (width, depth, and height) of the tray 60 to be stored.
  • grooves can be provided in the pair of support members 42a, 42a, and protrusions can be provided on the side walls 60e, 60e of the tray 60.

  • general items 21g and specific items 21t may be stored together. Furthermore, the number of items 21 used in the substrate-related operating machine 10 is greater for general items 21g than for specific items 21t. Therefore, the number of times general items 21g are stored and removed tends to be greater than the number of times specific items 21t are stored and removed, and the atmospheric humidity in the storage section 42 tends to fluctuate with the storage and removal of general items 21g.
