Filed:

Feb 7, 2002

Appl. No.:

10/068996

Inventors:

Peter Leibinger - Avon CT
Leonid Zeygerman - West Hartford CT

Assignee:

Trumpf, Inc. - Farmington CT

International Classification:

G06F 1900

US Classification:

700114, 156364, 271228

Abstract:

A machine tool installation includes a machine tool with a work support table, and a workpiece guidance system. Adjacent the machine tool is a sheet material loader and unloader with a frame, a platform supported on the frame for vertical movement, and a sheet material gripper mounted on the frame for movement from a position forwardly of the frame to a retracted position. A sheet pickup depends from the platform to engage the top sheet of a stack of sheets disposed therebelow. A computer control operates the elements to move a workpiece on the work support table to a position adjacent the platform, and the gripper moves the workpiece onto the lowered platform. The sheet pickup engages a sheet and the platform is moved upwardly to move the engaged sheet to a position above the plane of the work support table which is moved thereunder, and the sheet gripper deposits the sheet on the work support table.

Abstract:

A tool for machining workpieces by motion of the machining tool relative to the workpiece has a support extending in the X-axis over a work support table and movable in the Y-axis. A machining tool housing is movable on the support in the Y-axis. A portion of the housing containing the machining tool is movable with respect to the mounted portion in the Y-axis within a limited range of motion. A computer control effects operation of drive motors to move the housing along the support and the support along the machining tool table to machine a workpiece supported on said worktable in X and Y axes, and the computer control can also effect operation of another drive motor to rapidly move of the housing portion and machining tool in the Y-axis when the desired length of motion in the Y-axis is within its range of motion.
