ABSTRACT:
A pallet changer having additional distribution and storage functions for a manufacturing plant having a central control station, transfer stations at the conveying and storage part of the installation and address readers. The pallet changer comprises a rotatable part capable of rotating about a vertical axis and having pallet guides and pallet feed devices for pallets equipped with switching markers. The rotatable part can be rotated into four fixed change positions offset by about 90.degree. with respect to one another for changing the pallets at one, two or three transfer stations and at one or two machine tools. Rotation of the rotatable part is accomplished as a function of programmes infed to the central control station and by means of four non-rotatably arranged address readers dispositioned at a spacing of about 90.degree. from one another and with the same spacing from the axis of rotation. The address readers are activated by the address switching markers of the pallets inserted onto the pallet guides.
