MACHINE TOOL LOADING AND UNLOADING DEVICE

摘要

PURPOSE: A device for loading and unloading machine tools is provided which the device can be used efficiently. CONSTITUTION: A system for engaging a loading unit with a machine supported on a floor surface and in combination with the machine, comprises: the loading unit having a loading unit chassis; first and second fixing devices each including: a fixing piece fixedly disposed relative to the machine and at a side of the machine; the fixing piece having a receiving section; and a mating piece mounted at a side of the loading unit chassis and having a configuration for engagement with the receiving section of the fixing piece; the fixing pieces being disposed vertically displaced from one another on the side of the machine; the mating pieces being disposed vertically displaced from one another on the side of the loading unit chassis so as to permit simultaneous engagement with the fixing pieces such that the loading unit is cantilever supportable from the side of the machine; and a bearing structure having rollers for supporting the loading unit chassis on the floor surface, the bearing structure being displaceable relative to the loading unit chassis to permit vertical movement of the bearing structure relative to the loading unit chassis such that the loading unit chassis is vertically displaceable relative to the machine and the floor surface so as to permit engagement and disengagement of the first and second fixing devices and cantilevered support of the loading unit absent the rollers contacting the floor surface when the first and second fixing devices are engaged and the bearing structure and the rollers are vertically retracted upward.
