Abstract
An apparatus for the program controlled longitudinal and transverse cutting of workpiece plates. A longitudinal cutting saw and a transverse cutting saw are arranged with an intermediate workpiece transport table in-between. Arranged on the intermediate workpiece support table is a lifting device for collecting and lifting end strips cut from workpiece plates by the longitudinal saw above the plane of transport of the cut plate sections, as the cut plate sections are transported onto the transverse saw.
Claims3
An apparatus for the program-controlled cutting of workpiece plates into multiple workpiece plate pieces, said apparatus being operably arranged for longitudinal cutting of edge strip stacks from workpiece plate stacks, subsequent longitudinal sectioning of said workpiece plate stacks into workpiece plate piece stacks, transverse sectioning of said plate piece stacks cut from said workpiece plate stacks, and transverse sectioning of said edge strip stacks, said apparatus for the program-controlled cutting of workpiece plates into multiple workpiece plate pieces comprising:
- a longitudinal cutting saw for cutting said edge strip stacks from said workpiece plate stacks and for cutting said workpiece plate stacks into said workpiece plate piece stacks;
- a first advancing device for feeding said workpiece plate stacks to said longitudinal cutting saw;
- a first support table for supporting said workpiece plate stack as they are fed to said longitudinal cutting saw by said first advancing device;
- a transverse cutting saw for cutting said workpiece plate piece stacks and said edge strip stacks, operably arranged generally perpendicular to said longitudinal cutting saw;
- a second advancing device for feeding said workpiece plate piece stacks and said edge strip stacks to said transverse cutting saw;
- a second support table for supporting said workpiece plate piece stacks and said edge strip stacks as they are fed to said transverse cutting saw by said second advancing device;
- a transport device for moving said edge strip stacks and said workpiece plate piece stacks from said longitudinal cutting saw to said second support table;
- and
- a pick-up device for collecting each said edge strip stack as it is cut from a workpiece plate stack, up to a predetermined number of edge strip stacks,
- said pick-up device including a lifting device for raising said collected edge strip stacks to a holding position to permit said workpiece plate piece stacks to pass under said collected edge strip stacks and advance to said transverse cutting saw,
- said lifting device being operably arranged to collect said predetermined number of edge strip stacks so that once said predetermined number of edge strip stacks has been collected, operation of said longitudinal saw is interrupted, said lifting device lowers said edge strip stacks from said holding positions for advancing to said transverse saw for transverse cutting.
