Next, the operation of the shelving equipment having the luggage loading/unloading device and the two-stage lifting station of the above embodiment will be explained.

FIG. 20 shows a load 109 consisting of a container 16 and articles 114 placed thereon placed on the upper conveyor 5 and lower conveyor 6 of the shelf stacking lift 2, and the running of the shelf stacking lift 2 and the loading platform frame 3. This figure shows the state in which the cargo 109 is conveyed in the longitudinal direction and the vertical direction of the lift passage by lifting and lowering, and the cargo 109 is placed in the center of the upper conveyor 5 and the lower conveyor 6, and the conveyor The engaging members 40 on both sides of the direction are fitted into the engaging recesses 14 of the container 16, and each wheel 50 of each conveyor 5, 6 is placed on the high level upper surface 47 of the conveyor support rail 46, and the upper conveyor 5 is The upper frame 24 is held horizontally at the upper center, and the lower conveyor 6 is held horizontally at the upper center of the lower frame 25.

From the state shown in FIG.
If the conveyors 5 and 6 are to be carried into the upper and lower shelves at the same time, as shown in FIG. 5,
6 is gradually inclined so that its carry-in side end is lowered, and then the endless chain 4 is circularly driven in the carry-in direction by the conveyor drive device 30, so that the cargo 109 is placed on the shelf material 115 in the shelf. We will send them at the same time.

As shown in FIG. 22, after the cargo 109 has been sent to a predetermined position, the cargo frame 3 and the conveyors 5 and 6 supported thereby are gradually moved downward, and the cargo 109 is placed on the shelf material 115. then lower the upper conveyor 5 to the upper frame 2.
At the same time, the lower conveyor 6 is returned to the center position of the lower frame 25.

When carrying out items simultaneously from the upper and lower shelves using the upper conveyor 5 and lower conveyor 6,
First, each conveyor moving drive device 60 moves the upper conveyor 5 and the lower conveyor 6 toward the cargo 109 to be carried out, and inclines the ends of each conveyor 5 and 6 on the cargo side to be lower.
In this state, each of the conveyors 5 and 6 is further moved, and as shown in FIG. and each conveyor 5, 6 supported thereby
gradually raise the engaging member 40 into the engaging recess 1
4 and slightly raise the end of the lift passage side of the cargo 109, each conveyor drive device 30 drives the endless chain 4 of each conveyor 5, 6 in the unloading direction to move the cargo 109 onto each conveyor. The conveyors 5 and 6 are pulled up to the center and placed thereon, and then each conveyor 5 and 6 is moved to the upper center of the loading platform frame 3 to be in the state shown in FIG.

In the case where the cargo 109 discharged from the right shelf in Fig. 23 is to be delivered simultaneously to the left shelf opposite to that shelf as described above, each conveyor 5 and 6 is placed on the left shelf. , and tilt each conveyor 5, 6 so that its left end is lower. Then, as described above, move the endless chain 4 of each conveyor 5, 6 toward the left shelf in the carrying direction (left side By circulating the goods 109 on each conveyor 5 and 6 in the same direction as the direction of transport from the shelf, the goods 109 are simultaneously fed onto the shelf material 115 in the left shelf, and the goods 109 are fed to a predetermined position. After that, load frame 3
and each conveyor 5 supported thereby,
6 is lowered, and then the upper conveyor 5 is moved back to the center of the upper frame 24 and the lower conveyor 6 is moved back to the center of the lower frame 25.

When loading cargo on the floor conveyor 113 for loading/unloading onto the upper conveyor 5 and lower conveyor 6 of the shelf lift 2, the upper loading platform 79 and the lower loading platform 80 are stopped at the lower limit positions, and then the loading/unloading After the cargo 109 is conveyed onto the fixed conveyor 106 by the floor conveyor 113, the lifting drive device 91 is operated to raise the upper cargo tray 79, so that the cargo 109 is transported by the upper cargo tray 79.
Then, the cargo 109 is carried onto the fixed conveyor 106 by the loading/unloading floor conveyor 113, and then the lower loading platform 80 is moved upward to move the cargo 109 on the fixed conveyor 106 onto the lower loading platform. It is supported by 80 and rises.

Next, the upper stage conveyor 5 and lower stage conveyor 6 in the shelf stacking lift 2 are operated simultaneously, and the cargo on the upper loading platform 79 and the lower loading platform 80 is simultaneously taken up onto the respective conveyors 5 and 6.

In addition, when carrying out the cargo 109 on the upper conveyor 5 and lower conveyor 6 in the shelf stacking lift 2 through the two-stage elevating station 112 and the floor conveyor 113 for loading/unloading, the upper loading platform 7
9 and the lower loading platform 80 are stopped at the upper limit position, the upper stage conveyor 5 is opposed to the upper loading stage 79, and the lower stage conveyor 6 is moved to the lower loading stage 8.
0, and then operate the upper conveyor 5 and the lower conveyor 6 simultaneously to transfer the cargo 109 on the upper conveyor 5 and the lower conveyor 6 to the upper loading platform 7.
9 and the lower loading platform 80 at the same time.

Next, by operating the lifting drive device 91 in the downward direction to lower the upper loading platform 79 and the lower loading platform 80, the cargo on the lower loading platform 80 is first lowered onto the fixed conveyor 106, and then, The cargo on the fixed conveyor 106 is moved onto the floor conveyor 113 for loading and unloading, and then the lower loading platform 80
with the upper loading platform 79 stopped at the lower limit position.
is lowered, and the cargo on the upper loading platform 79 is placed on the fixed conveyor 106, and then the cargo on the fixed conveyor 106 is moved to the floor conveyor 113 for carrying in and out and carried out.

As described above, the two-stage lifting station 11
Two pieces of baggage can be transferred at the same time between 2 and the shelf stacking lift 2, and therefore the efficiency of carrying in and out of pieces between the floor conveyor 113 for carrying in and out and the multi-tiered stacked shelf row 1 can be further improved.

Note that as the fixed conveyor 106, any other conveyor may be used instead of the roller conveyor, and the frame 108 of the fixed conveyor 106 may be used instead of the roller conveyor.
may be fixed to the lower frame 72.
