At the diagonal upper end of each tray row, there is a dead space 6 corresponding to one tray. , 7 are formed, and each of the trays is configured to be cyclically moved by both the feeding devices in synchronization and simultaneously in opposite directions, that is, in a two-step system.

Further, the forklift 8 to be installed on either side of each tray row is connected to a lifting drive device 10 installed in the lower pit of the lift column 9, and mounted between the drive device and the lift column. It consists of an endless chain 11, a lifting frame 12 that is attached to the chain and moves up or down, and a counterweight 13.
When the elevating frame 12 is lowered from the position shown in the two-dot chain line to the position shown in the solid line as shown in FIG. At this time, the counterweight is in the downward position.

As shown in FIG. 3, a U-shaped female connecting fitting 14 is provided at the front and rear left side of each tray 1, and an inverted L-shaped male connecting fitting 15 is provided at the front and rear right side. A coupler 16 is formed by the engagement of the connecting fittings, and each of the trays is connected to the left side and right side traversing devices 4,
5, the trays are simultaneously and synchronously moved leftward and rightward or rightward and leftward. The tray 1 shown by the two-dot chain line is moved to the solid line position by the drive of the left vertical feeder 2, and at the same time, the tray 1, which had been on the dead space 7, is moved to the solid line position in FIG. I am forced to do it.

Next, as shown in FIGS. 1 and 3, the frame 1
Due to the structure or layout of the forklift 9, if there is a partition wall or column 20 in the space in front of the forklift 8, the tray cannot be pulled out from the forklift or pulled into the forklift.

Therefore, according to the present invention, an engaging/disengaging device 21 for the coupler 16 used to pull the tray 1 into the space in front of the lift or the space on the left side of the tray row on the near side is provided. , a pair of front fixed rails 22 and rear fixed rails 23 arranged in the vertical direction, a frame truck running on these rails, and a power cylinder 25.
The front girder 26 and the rear girder 27 of the frame truck are on the same level as the movable rail 18 attached to the drive chain 17 via crossover rails 28 and 29, and the pair of vertical girders 30 A tray 1 is placed on the front girder and the rear girder, and a front fixed rail 2 is placed at the bottom of the tray 1.
2 and a front wheel 33 and a rear wheel 34 running on the rear fixed rail 23 are installed, and the power cylinder 2 is mounted.
