Machining center with magazine for the tools

摘要

The mechanical machining center is associated with a magazine for the tools in which the tools are collected in two horizontal rows superposed on vertical frames (pallets) transportable by means of a rotatable handling device from the magazine to a position in which an exchange arm withdraws the tools and brings them to the spindle of the working head. The magazine is composed of a fixed structure with a variable number of modules disposed in the form of a fan around the rotatable handling device and in which the pallets complete with tools are accommodated. The pallets may be transported manually or with the aid of wire-guided trolleys from a central magazine to each module. The handling device comprises a rotatable carousel structure on which two cage-like frames for supporting the pallets are pivoted in diametrically opposed position. Normally, one of the two frames is in a loading position, while the other frame is in an exchange position close to the exchanger arm. The frame in the loading position can rotate on the structure of the handling device to align itself with each module of the magazine. Each cage-like frame is provided with a chain-type loading device for withdrawing a pallet of tools from the magazine of for carrying a pallet of used tools back to the magzazine. In exchanging position each frame is movable to bring the desired tool into correspondence with the exchange arm.
