The present invention provides an overhead travelling carriage system in which an overhead travelling carriageis run along a running rail to convey a cassettebetween processing devicesThe overhead travelling carriage system is provided with an elevating spacefor a platformon which transfer meansis provided to transfer the cassetteand a storage spacein which a plurality of shelves are provided in a vertical direction to store cassettesThe elevating space and the storage space are arranged in a direction orthogonal to the running rail, as viewed from above. According to the present invention, the stocker requires a reduced space.

Overhead travelling carriage system

The present invention provides a carrying apparatus that prevents an elevating motor and the like from projecting from a stacker crane to hinder the stacker crane from interfering with walls of an automatic warehouse. A traveling vehicleof a stacker crane comprises traveling driving meansfor wheelsand elevation driving meansfor elevating and lowering a platformBoth driving meansare arranged so that a longitudinal direction of both driving meansis almost parallel with a direction in which the traveling vehicleruns. The traveling vehiclecomprises a pair of framesspaced at a predetermined distance from each other and a plurality of connecting members that connect both framestogether. Both driving meansare arranged outside the respective framesWheelsare arranged in the front and rear, respectively, of the traveling vehicleThe traveling driving meansis connected to each wheelAn elevating pulleyfor the platformis arranged between the front and rear wheels. The elevation driving meansis connected to the elevating pulley

Carrying apparatus

A mast in a conventional stacker crane is configured to extend in a vertical direction. Accordingly, the mast is not sufficiently rigid, and may swing in a running direction during running or when the running operation is stopped. An attempt to increase the rigidity results in a thicker mast, thus increasing the size of the stacker crane. In order to solve this problem, a mast is extended vertically from a lower frame and a platform that elevates and lowers along the mast wherein a ladder is extended vertically at a position opposite to the mast across the platform in a direction in which the lower frame runs, and a top of the mast and a top of the ladder is connected together via an upper frame.

The present invention provides an automated guided vehicle system that can transfer an article between an automated guided vehicle and an automatic warehouse on the basis of easy control. In an automated guided vehicle system the vehicle A running on a running path is provided with a roller conveyor used to transfer an article. Further, automatic warehouses are each provided with an article storage and retrieval roller conveyor The transfer roller conveyor which runs with the vehicle A, and the storage and retrieval roller conveyor are arranged in series and in proximity to each other in a carrying direction. An article can be transferred between the vehicle A and the automatic warehouse The bottom surface of the article is formed as planar portions at its laterally opposite ends in the carrying direction. The transfer roller conveyor and storage and retrieval roller conveyor which carry the article are each provided with rows of rollers provided in the carrying direction. Planar portions at the opposite ends of each conveyor can be supported by the pair of roller rows

Automated guided vehicle system

A transferring apparatus which enables articles interlock-stacked on a pallet for a single-article to be bar-stacked on a shipping pallet includes lifters 4, 6 for shipping pallets (transferring pallets) B, C provided on the respective sides of a lifter 2 for a pallet for a single-article A, and a carriage 20 which picks up one layer of articles at a time from the pallet for a single-article A and alternatively transfers the layers of articles to the two transferring pallets B, C. According to this configuration, it is possible to load only odd- or only even-numbered layers of the pallet for a single-article A onto the transferring pallets B, C.
