Abstract
The invention relates to a production method for handling plates to be cut out of a plate blank. The production method is effected via a production system by carrying out a variety of working operations in an integrated manner, at a so-called plate working center, with a shearing mechanism, an unloading and handling mechanism, as well as a single or multi-section conveyor mechanism serving as a buffer conveyor storage therebetween, the mechanisms being computer controlled.
Claims18
In an environment wherein material and information flows are computer controlled, a production method for handling plates cut from a plate blank comprising the steps of:
- (a) cutting a plate blank by means for a shearing mechanism into plates of at least one predetermined shape;
- (b) transferring said plates successively cut from said plate blank onto a conveyor mechanism having at least two successive conveyors for transport to an unloading end;
- (c) operating said conveyor mechanism intermittently during said cutting operation for receiving and transporting said plates to said unloading end;
- (d) removing reject material and small pieces from said conveyor mechanism by moving vertically at least one end of at least a first conveyor of said conveyor mechanism;
- (e) unloading said plates from said unloading end by means of an unloading and sorting mechanism;
- (f) operating said conveyor mechanism, said shearing mechanism and said unloading and sorting mechanism as a flexible production system;
- and
- (g) using said intermittently operated conveyor mechanism as a buffer conveyor storage for compensating momentary differences in the operating speeds of said shearing mechanism and said loading and sorting mechanism.
In an environment wherein material and information flows are computer controlled, a system for handling plates cut from a plate blank comprising:
- a shearing mechanism for cutting a plate blank into plates of at least one predetermined shape;
- a conveyor mechanism having at least two successive conveyors and being operated intermittently during said cutting operation for receiving and transporting said plates successively cut from said plate blank to an unloading end, said conveyor mechanism further including:
- at least a first conveyor having at least one end thereof moving vertically for removing reject material and small pieces from said conveyor mechanism;
- an unloading and sorting mechanism for unloading said plates from said unloading end;
- and
- computer means for controlling the operation of said conveyor mechanism, said shearing mechanism and said unloading and sorting mechanism as a flexible production system by using said intermittently operated conveyor mechanism as a buffer conveyor storage for compensating momentary differences in the operating speeds of said shearing mechanism and said loading and sorting mechanism.
