Abstract

A container raising/lowering conveyance apparatus is provided with: rod-shaped gripping raising/lowering bodies which are long in a raising/lowering direction, and which are supported so as to be capable of being horizontally fitted to and detached from corners of a container; and lifting raising/lowering bodies in which supporting implements protruding towards two parallel side surfaces of the container are provided to rod-shaped main bodies which are long in the raising/lowering direction and are capable of being moved closer to and away from the two parallel side surfaces of the container. When the supporting implements are moved closer to the two parallel side surfaces of the container, the supporting implements are inserted underneath a flange portion at the two parallel side surfaces of the container, and when the rod-shaped main bodies are raised, the supporting implements lift the container via the flange portion.

First claim

What is claimed is:

1. A container raising/lowering conveyance apparatus that peripherally grips and raises and lowers an article-conveying container with a right-angled parallelogram planar shape, characterized in comprising four gripping raising/lowering bodies, respectively corresponding to four corners of the container and at least two lifting raising/lowering bodies respectively corresponding to two parallel side surfaces of the container, and having a configuration where the respective gripping raising/lowering bodies are rod-shaped bodies, each being long in a raising/lowering direction and including a fitting portion of angle-shaped transverse section capable of being fitted to a container corner along adjacent vertical side faces of the container, and are supported by a supporting structure so as to be capable of being raised and lowered and capable of being respectively horizontally fitted to and detached from the four corners of the container, each of the lifting raising/lowering bodies has a rod-shaped main body, which is long in the raising/lowering direction, provided with a supporting implement protruding towards the container and has the rod-shaped main body supported by the supporting structure so as to be capable of being raised and lowered and capable of horizontally moving closer to and away from a side surface of the container, and the supporting implements are inserted underneath a protruding portion at container side surfaces upon being moved closer to the container side surfaces and lift the container via the protruding portion when the rod-shaped main bodies are raised.

2. The container raising/lowering conveyance apparatus according to claim 1 , wherein the rod-shaped main body of each of the lifting raising/lowering bodies is disposed in correspondence to a center position of a horizontal direction length of the corresponding container side surface, the supporting implement is mounted, at each of symmetrical positions at respective sides of the center position, to a base plate mounted to the rod-shaped main body, and the two supporting implements are configured to lift a flange portion of the corresponding container side surface at the same time.

3. The container raising/lowering conveyance apparatus according to claim 1 , wherein the fitting portions of the respective gripping raising/lowering bodies have a raising/lowering direction length enabling simultaneous fitting to corners of a plurality of stacked containers and the supporting implements of the respective lifting raising/lowering bodies are provided at least at positions corresponding to a container at a lowest stage among the stacked plurality of containers.

4. The container raising/lowering conveyance apparatus according to claim 1 , wherein with each of the lifting raising/lowering bodies, the supporting implement is provided at each of at least at two upper and lower parts at a position corresponding to the container at a lowest stage among the stacked plurality of containers and a position corresponding to a container of intermediate height.

5. The container raising/lowering conveyance apparatus according to claim 1 , wherein a traveling body, supported in a manner enabling front/rear direction movement and right/left direction movement so as to be capable of covering an entirety of a storage area, including a horizontal supporting surface dispersingly supporting the container in a fixed orientation in all of front/rear and right/left directions and an entrance/exit of a container conveying conveyor, is supported at an upper side of the storage area, and the traveling body constitutes the supporting structure.

6. The container raising/lowering conveyance apparatus according to claim 5 , wherein the respective gripping raising/lowering bodies and the respective lifting raising/lowering bodies are configured to be capable of being raised and lowered, together with a supported container, inside an vertical direction through opening portion provided at the traveling body.
