おいて公知である。2. Description of the Related Art Conventionally, conveyors on which pallets for carrying cargo are placed are arranged in upper and lower tiers, and there are elevators for raising and lowering the conveyor between an upper floor and a lower floor. On the floor surface, similarly to the above, a fixed support provided with conveyors on which pallets are placed in upper and lower stages, and an elevating table composed of a pantograph mechanism having a conveyor on the upper surface are provided, and the elevator is stopped in a stopped state. A configuration in which each conveyor is driven individually to transfer a mounted pallet loaded with luggage and an empty pallet not loaded with luggage horizontally to transfer empty pallets and carry in / out luggage between conveyors at the same time.

なるなどの不都合があった。According to the above-mentioned conventional construction, for example, in the case of transporting goods by using a truck, the truck is operated on a floor surface and mounted on an empty pallet on a lift table or lifted. In order to transfer the trolley from the pallet mounted on the pedestal to the floor, the trolley mounting surface on the elevating platform must be flush with the floor. At the lowest position of the lifting platform, it was necessary to provide a dug-down portion so that its mounting surface was equal to the floor surface. For this reason, the provision of the dug-down portion on the floor surface, particularly on the upper floor, may not only cause the floor panel to be weakened, but also make it difficult to install the apparatus itself.

ものである。Therefore, in the present application, the position of the pallet when loading and unloading cargo to and from the floor can be made as close to the floor as possible, instead of the conventional elevator. The present invention provides a simple elevating device and omits the configuration of a dug-down section that is conventionally required. That is, a pair of front and rear apparatus main bodies having an elevating mechanism which is erected on the floor surface in a direction orthogonal to the transfer direction and reciprocates in the height direction, and along the front surface of the apparatus main body by the elevating mechanism. A mounting member that moves up and down, and a transfer device that is mounted on the mounting member and that supports a pallet for loading and unloading and transfers the pallet in the width direction of the apparatus main body. A support member attached to the member and extending horizontally in the transfer direction, and spaced along the longitudinal direction of the support member, and
The lower end is composed of a plurality of transfer members rotatably fixing a disk supporting the pallet, and a drive mechanism for simultaneously rotating the disks of the transfer member in the same direction by motor driving, the disk having an umbrella-like upper surface. The load carrying pallet has an inclined surface, and the lower surface of the pallet for loading and unloading is parallel to the inclined surface of the upper surface of the disk of the transfer member. In this case, a contact member inclined upward and outward is attached.

角で充分である。The lifting device according to the present invention is placed on the floor so as to be close to the fixed support in the transporting device for the pallet for loading and unloading cargo, and to face each other in a direction perpendicular to the transport direction. In addition, the transfer mechanism supports an empty pallet in advance, and in a standby state for receiving the carriage, the disk is placed at the lowest position closest to the floor by the lifting mechanism. Then, when transferring the trolley on which the load is placed from this standby state to the upper conveyor of the fixed support using an empty pallet, first use the slope table on the empty pallet supported by the transfer mechanism. The truck is mounted. In this case, since the pallet support level is at the lowest position closest to the floor surface, and the height of the disk can be lower than that of other transfer means such as rollers and trochanters, the slope table should have a very gentle inclination angle. It is.

待機状態に復する。When transferring an empty pallet from the lower conveyor of the fixed support to the transfer device, the transfer mechanism is lowered to a low position facing the lower conveyor by an elevating mechanism, and in this state, the lower conveyor of the fixed support is transferred. And the disk is rotated by the drive mechanism. The empty pallet is then transferred from the lower conveyor of the fixed support to a lower transfer mechanism. Next, from this state, the transport mechanism is lowered by the lifting mechanism to the lowest position where the disk is closest to the floor surface, thereby returning to the standby state for receiving the cart on the empty pallet.

点を有する。As described above in detail, according to the lifting device of the present invention, the disk can be brought as close as possible to the floor surface and the pallet supporting level can be minimized. It is not necessary to provide a digging part on the surface, so there is no danger that the floor will be weakened, and the slope of the slope base used when transferring the bogie between the floor and the transfer mechanism will be extremely gentle. In particular, according to the configuration of the third aspect, the moving mechanism can be moved up and down very smoothly, and according to the configuration of the fourth aspect, the rotational drive of the disk can be performed. It has advantages such as smoothness.
