As shown in FIG. 6A, the fork 5 is provided with a transfer device side wheel shaft support portion (hereinafter simply referred to as a wheel shaft support portion 61) that supports the wheel shaft 2. The fork 5 includes a top fork 62 to which the wheel shaft support 61 is attached, a second fork 63 for guiding the top fork 62 to slide, and a base fork 64 for guiding the second fork 63 to slide. A rack and pinion mechanism or a chain mechanism is provided between the top fork 62 and the second fork 63. A rack and pinion mechanism or a chain mechanism is also provided between the second fork 63 and the base fork 64. When the motor 65 attached to the base fork 64 rotates a pinion or sprocket provided on the base fork 64, the second fork 63 moves in the left-right direction by a rack and pinion mechanism or a chain mechanism. In addition, as the second fork 63 moves in the left-right direction, a pinion or sprocket provided on the second fork 63 rotates. When the pinion or sprocket of the second fork 63 rotates, the top fork 62 moves in the left-right direction by the rack and pinion mechanism or the chain mechanism. The second fork 63 and the top fork 62 move linearly in conjunction with each other. The top fork 62 can move linearly in both the left direction and the right direction. When the motor 65 is rotated in one direction, the top fork 62 moves to the left, for example, and when the motor 65 is rotated in the opposite direction, the top fork 62 moves to the right.

  As shown in FIG. 7A, the wheel shaft support portion 61 is elongated in a direction orthogonal to the moving direction of the top fork 62, and the top fork 62 and the wheel shaft support portion 61 intersect in a cross shape. The upper surface of the wheel shaft support portion 61 of the top fork 62 is formed flat so that the pallet can also be supported. A rim receiving surface 66 that contacts the rim portion 42a of the wheel 42 of the wheel shaft 2 is formed at both ends in the length direction of the wheel shaft support portion 61 (see also FIG. 6A). A flange escape groove 67 that escapes from the flange 42 b of the wheel 42 of the wheel shaft 2 is formed on the inner side of the rim receiving surface 66. A gear box receiving surface 68 that is in contact with the gear box 43 of the wheel shaft 2 is formed inside the flange clearance groove 67.

  As shown in FIG. 7A, the rim receiving surface 66 is formed in a V shape and prevents the wheel 42 from rolling back and forth. As shown in FIG. 8C, the rim receiving surface 66 of the wheel shaft support portion 61 contacts the wheel 42 in the middle of the two places P1 and P2 before and after the rim receiving surface 51 of the shelves 3a and 3b contacts the wheel 42. . As shown in FIGS. 7A and 7B, the gear box receiving surface 68 is in contact with the lower surface of the gear box 43 and prevents the gear box 43 from rotating with respect to the axle 41.

  With reference to FIG.8 and FIG.9, the process at the time of taking out the wheel shaft 2 supported by shelf 3a, 3b is demonstrated. When the wheel shaft 2 supported by the shelves 3a and 3b is taken out, as shown in FIG. 8C, first, the top fork 62 is horizontally moved in one direction toward the shelves 3a and 3b, and the top fork 62 is moved to the rack beam 31a. Move to below 31d. As shown in the plan view of FIG. 8A, when the top fork 62 is moved below the rack beams 31a to 31d, the wheel shaft support portion 61 of the top fork 62 and the rack beams 31a to 31d overlap in a plane. There is nothing. For this reason, it becomes possible to raise the wheel-shaft support part 61. FIG. Next, as shown in FIG. 9A → FIG. 9B, the top fork 62 and the wheel shaft support portion 61 are raised by raising the elevating body 32. Then, the receiving surface 66 of the wheel shaft support portion 61 comes into contact with the wheel 42 of the wheel shaft 2 and lifts the wheel shaft 2. As shown in FIG. 9B, the wheel shaft support portion 61 rises to the upper side of the rack beams 31a to 31d so as to avoid the rack beams 31a to 31d. Next, if the top fork 62 is horizontally moved in the opposite direction, the wheel shaft 2 can be moved onto the lifting body 32 of the stacker crane 4. When the wheel shaft 2 is placed on the rack beams 31a to 31d of the shelves 3a and 3b, the fork 5 performs the reverse operation.

  The overall operation of the automated warehouse is as follows. When the loading / unloading cart 11 on which the wheel shaft 2 is mounted moves to the loading / unloading port 1, the stacker crane 4 moves to the loading / unloading port 1, and the fork 5 pulls the wheel shaft 2 from the loading / unloading cart 11 onto the lifting body 32. Thereafter, the stacker crane 4 moves the wheel shaft 2 to the intended accommodating portion 21 of the shelves 3a and 3b. When the wheel shaft 2 is moved to the target housing portion 21, the fork 5 of the stacker crane 4 stores the wheel shaft 2 in the target housing portion 21. Thus, the receipt of the wheel shaft 2 is completed. When the wheelset 2 is unloaded, the reverse operation is performed. That is, the stacker crane 4 moves to the target accommodating portion 21, and the fork 5 pulls the wheel shaft 2 from the target accommodating portion 21 onto the lifting body 32. Thereafter, the stacker crane 4 moves to the loading / unloading port 1 and delivers the wheel shaft 2 to the loading / unloading cart 11.

  According to the automatic warehouse of the present embodiment, the following effects can be obtained. By directly supporting the wheels 42 of the wheel shaft 2 by the rack beams 31a to 31d of the shelves 3a and 3b, the loaded state of the wheel shaft 2 is stabilized, and it is possible to maintain stability against earthquake shaking. In addition, since the racks 31a to 31d and the wheel shaft support portion 61 that are in contact with the gear box 43 of the wheel shaft 2 are provided on the shelves 3a and 3b and the fork 5, both the dynamic shaft 2a and the driven shaft are stably put in and out of the shelves 3a and 3b In addition, it is possible to prevent the lubricating oil filled in the gear box 43 from leaking due to the inclination of the gear box 43 of the moving shaft 2a. Furthermore, by not using a pallet for storing the wheel shaft 2, work for loading and unloading the pallet and taking in and out of an empty pallet are eliminated, so that work safety and efficiency can be improved.

  The rack beams 31 a to 31 d of the shelves 3 a and 3 b are in contact with two places P 1 and P 2 before and after each wheel 42 of the wheel shaft 2, and the wheel shaft support portion 61 of the fork 5 is placed at two places P 1 and P 2 before and after each wheel 42. By being in contact with each other, the wheel shaft 2 can be stably supported, and the fork 5 can receive the wheel shaft 2 from the shelves 3a and 3b.

  The wheel shaft support 61 of the fork 5 moves horizontally in one direction below the rack beams 31a to 31d, then lifts the lifting body 32 to lift the wheel shaft 2, and then the upper side of the rack beams 31a to 31d in the opposite direction. Since the wheel shaft 2 is taken out by moving horizontally, the wheel shaft support portion 61 of the fork 5 can be prevented from interfering with the rack beams 31a to 31d of the shelves 3a and 3b.

  By forming the receiving surfaces 51 of the rack beams 31a to 31d and the receiving surface 66 of the wheel shaft support portion 61 of the fork 5 in a V shape, it is possible to prevent the wheel shaft 2 being stored or transported from rolling and dropping.

  Since the upper surfaces of the rack beams 31a to 31d and 74a to 74d and the upper surfaces of the wheel shaft support portions 61 and 81 of the top fork 62 are formed flat, an ordinary automatic warehouse can be used for articles other than the wheel shaft 2 if a separate pallet is used.
