Tool magazine
A tool magazine exhibits a storage wheel, on the circumference of which there are attached, in the direction of its rotational axis protruding in both directions, tool receivers designed to receive tools. To transport the tools to a tool changer arranged on one side of the storage wheel there is provided a tool handover device, which is movable by means of a 4-position drive. To also enable the tools arranged to face away from the tool changer to be transported, the storage wheel exhibits passage opening that is open towards its circumference.
