Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention applies to a loading/unloading device for a rotary rack in which various cargoes are stored in a large number of rack bodies that can be circulated.

[Prior art] Conventional rotary racks have a machine frame set up at the loading/unloading position, and a lifting platform with a handing device is attached to the frame to receive goods, or a lid-type loading/unloading device is used. The loading and unloading capacity is small because the lift platform for the handover lid needs to be raised and lowered between the objects 11 each time to receive or pass the goods, and then returned to the position of the warehousing line or the warehousing line. For this reason, attempts have been made to improve the capacity by installing a plurality of lids, but this results in an increase in the installation space of the entire loading and unloading device. In addition, the elevating platform has a loading/unloading device, and in order to place the cargo on it and move it up and down smoothly, it is necessary to assemble a relatively large machine frame with sufficient strength. had become complicated.

LObject of the Invention] An object of the present invention is to provide a warehousing/unloading device that has a large warehousing/unloading capacity and requires a small installation space by arranging an elevating tray conveyor at the warehousing/unloading position.

[Summary of the Invention] According to the present invention, an elevating tray conveyor is disposed at the loading/unloading position of a rotary rack, and a loading/unloading button is attached to each stage of the rack. The rotary rack has a structure in which a tray-shaped rack body connected to an elliptical guide rail by an endless chain ring can be circulated in multiple stages, and each stage can be moved separately.

An elevating type tray conveyor consists of at least one pair of endless chains arranged facing each other across the vertical surface of the loading/unloading area, with the same pitch as the upper and lower rack openings, and the same side as the chain always faces when running. It consists of a plurality of sets of tray members mounted on a level chain and a drive @ for synchronously operating the pair of endless chains. Since the tray conveyor supports both lower edges of the cargo by opposing tray members, it is possible to smoothly receive the cargo, load it onto the target rack, unload it, or unload the cargo.
