Abstract
Abstract A rotary support is mounted on the frame of a machine tool for rotation about an axis, and a plurality of carriers is distributed along a major surface of the rotary support and connected thereto to share its rotation about the axis. Each of the carriers has a carrier axis, and the rotary support can be indexed between a plurality of positions in each of which one of the carrier axes extends parallel to a horizontal plane and other carrier axis extends normal thereto. The carrier axes may intersect the axis of rotation of the rotary support, or they may be offset therefrom so as to generate a hyperboloid during the rotation of the rotary support. The rotary support may be used for moving workpieces toward a tool and a workpiece-transporting arrangement may be associated with the rotary support for supplying workpieces thereto and removing finished workpieces therefrom. The workpiece-transporting arrangement has only two degrees of freedom of movement, one of them coinciding with the carrier axis which extends normal to the plane. The carriers may be driven into rotation about their respective carrier axes in at least one of said positions.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
163 words
In a machine tool, a combination comprising a frame; a support mounted on said frame for rotation about a support axis; a plurality of carriers mounted on said support so as to share the rotation thereof about said support axis, each of said carriers having a carrier axis and a supporting surface substantially normal to said carrier axis; means for indexing said support about said support axis between a plurality of positions in each of which one of said carrier axis is substantially normal to a horizontal plane and the respective supporting surface faces downwardly and another carrier axis is substantially parallel to said plane; and conveyor means for supplying workpieces to a respective carrier the carrier axis of which extends normal to said plane, and for withdrawing finished workpieces therefrom, including a lifting table, and means for lifting said table toward said respective supporting surface so as to bring a workpiece supported on said table into contact with said respective supporting surface.
Claim 2
Dependent Claim
163 words
In a machine tool, a combination comprising a frame; a support mounted on said frame for rotation about a support axis; a plurality of carriers mounted on said support so as to share the rotation thereof about said support axis, each of said carriers having a carrier axis and a supporting surface substantially normal to said carrier axis; means for indexing said support about said support axis between a plurality of positions in each of which one of said carrier axis is substantially normal to a horizontal plane and the respective supporting surface faces downwardly and another carrier axis is substantially parallel to said plane; and conveyor means for supplying workpieces to a respective carrier the carrier axis of which extends normal to said plane, and for withdrawing finished workpieces therefrom, including a lifting table, and means for lifting said table toward said respective supporting surface so as to bring a workpiece supported on said table into contact with said respective supporting surface.
Claim 3
Dependent Claim
20 words
A combination as defined in claim 1, and further comprising means for rotating said carriers about their respective carrier axes.
Claim 4
Dependent Claim
30 words
A combination as defined in claim 2, wherein said rotating means is operative for rotating a respective carrier at least when said carrier axis thereof extends parallel to said plane.
Claim 5
Dependent Claim
19 words
A combination as defined in claim 1, and further comprising means for attaching a workpiece to a respective carrier.
Claim 6
Dependent Claim
