Abstract

Abstract An automatic numerically controlled slotting or notching press arrangement which includes a multi-armed feed and removing device having a turnstile or turntable which is selectively indexed or rotated so as to convey blanks to various processing stations. The feeding and removing device is adapted to transfer the blanks from at least one stack unloading station to a centering or aligning station, a locating or turning station, a processing station, a stator stacking station, and a rotor stacking station. A numerically controlled indexing unit (a clamping table for blanks to be processed) and a numerically controlled tool changing is provided. The stack unloading station and the rotor stacking station form the first and last processing stations and are linked by a conveying device which operates independently of the turnstile or turntable of the feeding and removing device.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 126 words
A numerically controlled automatic notching arrangement for notching blanks, the arrangement comprising at least one stack unloading station, an aligning station, a processing station, a first stacking station and a second stacking station, at least one notching machine having a numerically controlled tool changing means, and a multi-armed feeding and removing means including an indexable turntable for conveying blanks between at least one said stack unloading station, said aligning station, said processing station, said first stacking station and said second stacking station, characterized in that conveyor means are provided for linking the stack unloading station with the second stacking station, said conveyor means being driven independently of the indexable turntable whereby blanks may be selectively conveyed from the second stacking station to the stack unloading station.
Claim 2
Dependent Claim 126 words
A numerically controlled automatic notching arrangement for notching blanks, the arrangement comprising at least one stack unloading station, an aligning station, a processing station, a first stacking station and a second stacking station, at least one notching machine having a numerically controlled tool changing means, and a multi-armed feeding and removing means including an indexable turntable for conveying blanks between at least one said stack unloading station, said aligning station, said processing station, said first stacking station and said second stacking station, characterized in that conveyor means are provided for linking the stack unloading station with the second stacking station, said conveyor means being driven independently of the indexable turntable whereby blanks may be selectively conveyed from the second stacking station to the stack unloading station.
Claim 3
Dependent Claim 29 words
An arrangement according to claim 1, characterized in that means are provided for adjusting the at least one notching machine radially with respect to a blank to be processed.
Claim 4
Dependent Claim 20 words
