Baggage 22 such as bucket bags is stored in the shelf spaces of the multi-tiered stacked shelf row 8, and a portion of the cargo 22 protrudes beyond the multi-tiered stacked shelf row 8 toward the lift path side. When carrying out the cargo 22 from the shelf to the shelf lift, the upper conveyor 6 is raised in advance as shown in FIG. 22, and then the lifting frame 3
is moved upward slightly, and the protruding end of the baggage 22 is slightly lifted by the end of the lower conveyor 5.

Next, the conveyor lift drive device 7 is operated in the downward direction, and the lift member 27 and thereby the hanging member 2 are
When the holding frame 28 and the upper conveyor 6 supported via the carriers 9 are moved downward, the end of the upper conveyor 6 first hits the upper surface of the end of the baggage 22, and the upper conveyor 6 and the holding frame 28 are moved downward. stops moving downward, and then the elevating member 27
As the elastic pressing spring 31 is compressed by the downward movement of the conveyor 6, the end of the upper conveyor 6 is elastically pressed against the upper surface of the end of the baggage.

Next, the conveyor drive device 43 drives each lower conveyor 5 and upper conveyor 6 in the load drawing direction, and the load 22 is drawn to a predetermined position on the traversing frame 4 by these conveyors. Next, the traversing frame 4 is moved laterally until its center reaches near the center of the lift passage, and then the shelf lift is moved toward the unloading station.

When unloading the cargo 22 transported by the shelf lift to the loading/unloading station, the lower conveyor 5
With the baggage gripped by the upper conveyor 6, the transverse frame 4 is moved toward the station, and the lower conveyor 5 and the upper conveyor 6
is driven in the baggage sending direction to place the baggage on the upper part of the station, and then the conveyor lift drive device 7 moves the upper conveyor 6 up and down, and the lifting frame 3 is moved down to lower the baggage onto the station. Next, the transverse frame 4 is returned to its original position.

Note that when the shelf stacking lift receives packages from the station and when loading packages from the shelf stacking lift into the shelving bins, the packages are carried in and out in the same manner as in the above-mentioned case.

When implementing this invention, the belts 56 and 57 of the lower conveyor 5 and the upper conveyor 6 are as follows.
Rubber belts, fiber belts, metal mesh belts, etc. can be used, and the surface of the belt has
In order to reliably prevent slipping, a large number of protrusions or protrusions or brush-like protrusions may be provided.
Further, as the lower conveyor and the upper conveyor, a roller chain conveyor or any other type of conveyor may be used.

According to this invention, when receiving the baggage 22 from a shelf or station, the end of the lower conveyor 5 is placed under the bottom surface of the end of the baggage, and then the lifting frame 3 is moved slightly upward to move the end of the lower conveyor 5. The end of the baggage 22 is slightly lifted by the upper part, and the upper conveyor 6 is lowered by the conveyor lift drive device 7 via the lifting member 27, the hanging member 29, and the holding frame 28, and the upper conveyor 6 is placed on the top surface of the baggage. After contact, the conveyor lifting drive device 7
The lifting member 27 is further lowered by the force of the elastic pressing spring 31 to press the upper conveyor 6 against the upper surface of the load, and then the lower conveyor 5 and the upper conveyor 6 are driven synchronously in the load drawing direction. Therefore, the lower conveyor 5 and the upper conveyor 6 can securely grip the load without slipping and move the load to a predetermined position in a stable state and without scratches. Furthermore, when delivering the cargo to a shelf or station, the lower conveyor 5 and the upper conveyor 6 grasp the cargo, and as in the case described above, keep the cargo in a stable state and prevent it from being scratched. In addition, since the upper conveyor 6 is pressed by the conveyor lifting drive device 7 via the elastic pressing spring 31, when the upper conveyor 6 is pressed against the load, there is no impact on the load and damage to the load. The upper conveyor 6 can be pressed against the baggage with an appropriate pressing force without the risk of causing the baggage to move.Furthermore, there are four pillars 24 arranged at intervals in the longitudinal and lateral directions on the transverse frame 3. 25 and a holding frame 28 to which the upper conveyor 6 is fixed, and the elevating member 2
7 are slidably fitted to each of the above-mentioned supports, so that effects such as being able to move the elevating member 27 and the upper conveyor 6 up and down in a stable state can be obtained.
