While supporting the bottom surface, grip the side surface and center it. After centering, the second gripping hand 47 ascends along the guide member 46 and lifts the container lO storing the gripped item B to the vicinity of the base 24 of the item retrieval tool 20, as shown in FIG. 4(C). , as shown in (d), the tip of the partition 21 and the guide member 27 protrude downward from the base 24.
is inserted into the container 10 containing the item B, and then stopped. Therefore, Yong! First, the guide member 27 is inserted into the gap I2 formed by four items B among the items B arranged in a matrix on '1i10, and then the partition 2
Since the tip of the container IO is inserted, the items B stored in the container IO can be reliably separated into individual items. In addition, when the item ejecting tool 20 and the container 0 storing the item B are stacked on top of each other, if a gap δ of approximately 5 cm is left as shown in FIG. 4(C), the item B can be removed from the container 10 Item removal I4
20 can be transferred smoothly.

As described above, when the base 24 of the item removal tool 20 and the opening 11 of the container 10 are overlapped, the reversing device 40
is driven to invert the item removal tool 20 and the container 10 containing the item B as shown in FIG.

That is, the first and second gripping hands 45, 47 and the guide member 46 are reversed counterclockwise in FIG. 2 with the rotation shaft 44 as a fulcrum.

To explain this reversing operation in more detail, after the first gripping hand 45 rotates approximately 170'' counterclockwise, the traveling platform 42 moves backward, and the article retrieving tool 20, which is in the reversing process, is moved onto the surface of the main article cutting tool 80a. After the first gripping hand 45 is further rotated approximately 10 degrees counterclockwise, the article extracting tool 20 and the container lO containing the article B are superimposed on the main article cutting tool 80a. Due to this reversing operation, the items B stored in the container 10 are separated one by one by the partitions 21, and the items B stored in the container 10 are separated by the item removal tool 20

The shutters 83 corresponding to the item rows are sequentially opened to release the item B.
is dropped into the chute 91 and all the articles B are cut out from the main article cutting tool 80a, then the shutter 22 of the article removing tool 20 is opened in the direction of the arrow in FIG. All items B are automatically transferred to the main item cutting tool 80a.

Next, a mode of transferring items that are transferred infrequently will be explained.

When transferring an article from the auxiliary take-out lower part 1b in which articles that are not frequently transferred are stored to the auxiliary article cutter 80b, since the auxiliary take-out lower part 1b and the auxiliary article cutter 80b do not face each other, When the empty item removal tool 20 placed on the auxiliary item removal tool 80b is grasped and the reversing device 40 is in the state shown by the solid line in FIG. As the carriage 50 moves up and down, the auxiliary retrieval interval lower 1b stores articles to be replenished.
Container 1, which has moved to a position opposite to , and stores item B
After the reversing device 40 has rotated approximately 1,700 times counterclockwise or while rotating, the stacker crane 60 is moved and the carriage 50 is rotated. As the carriage 50 moves up and down, the carriage 50 returns to the predetermined auxiliary article cutting tool 8.
After moving to the position facing 0b, the reversing device 40 further rotates approximately 10 degrees counterclockwise, and the auxiliary article cutting tool 80
Place the item removal tool 20 and container 10 on top of b.

As described above, after an article that is frequently transferred or an article that is infrequently transferred is placed on the article cutting tool 80 via the article picking tool 20, the article B transferred to the article cutting tool 80 According to the desired number of pinking commands, for example, as shown in FIG. The container is transported to a desired container or the like (not shown). Incidentally, since the plurality of chutes 91 are connected to one spiral shade 90 at different heights, different types of articles B can be collected from the plurality of article cutting tools 80 almost simultaneously into one container. It is possible to automatically arrange the grapes.

In addition, FIG. 6(a) [present]) is a front view of each as seen from the traveling rail 61 side for explaining the arrangement of the articles placed on the unloading lower lower 1 and the article cutting tool 80. It is a diagram.

That is, as shown in Figure 6, items that are frequently transferred (1
) to Q6) are placed on the main take-out lower lower 1a, which is arranged to face the main article cutter 80a, and the main article cut-outs are removed from the main take-out lower lower 1a based on an article transfer command. At 80a, there is a container 10 storing the item B via the item retrieval tool 20! ! There is no such thing as it is placed. Therefore, articles (1) to Oe that are frequently transferred can be transferred to the lower 1. The articles can be efficiently transferred from the main article cutting tool 80a to the main article cutting tool 80a. In addition, since the work range of one stacker crane 60 is 70 units of fluidized shelves, the stunker crane 60 moves items (1) to 0ω that are frequently transferred to interference control zones Z, 1, Z, etc.
...Since items can be transferred without entering the container, there is no waiting time for interference and items can be transferred extremely efficiently.

Also, are the items O to [phase] that are transferred less frequently located at the main removal frontage? The item cutting tool 80 is sandwiched between la.
is placed on the auxiliary take-out lower lower 1b arranged with a step, and based on the article transfer command, the part where the flow JIA 70 is not installed, that is, each flow shelf 70 The item is taken out I42 by the auxiliary item cutting tool 80b disposed facing the space interposed therebetween.
0 so that the container 10 containing the item B is placed thereon. Therefore, it is necessary to move the stacker crane 60 to transfer the articles, but since the fluidizing shelves 70 are arranged intermittently through a plurality of spaces,
The probability that adjacent stacker cranes 60, 60 will interfere with each other can be reduced. Further, as described above, interference control zones Lh, Z, I... are provided on the traveling rail 61, which is the traveling route of the stacker crane 60, and any of the adjacent stacker cranes 60, 60 is in the interference control zone Zmb. , Zl,... or the interference control zone Z&hs zbc,...
