Abstract
The cutting machine comprises a horizontal knife (17) for cutting a block (40) into plates (41). To allow for removal of a stack of plates (42) before the whole block (40) has been cut, a removal means comprising a removal conveyor (32) is provided. After completion of the last cut, the knife (17), after reversal of its cutting edge, will be entered into the cutting gap (43) again and be lifted, thus allowing a separating member (34) of the removal conveyor (32) to enter the resultant gap (44). By driving the conveyer belt (12), the stack of plates (42) is transferred onto the removal conveyor (32).
Claims11
A cutting machine for cutting blocks of material into plates and forming stacks of said plates, said cutting machine comprising:
- a knife for cutting horizontally through a block, said knife extending transversely across the working width of the machine and being arranged for horizontal movement relative to the block, and
- a removal means comprising a height-adjustable removal conveyor and a separating member arranged to grip under, lift and transfer a stack of plates onto the removal conveyor, wherein the knife being controlled in such a manner that, after completion of a cut through the block, the knife being reversed and entering the block again, and finally being moved upwards and lifting the stack of plates from the block.
A method for cutting blocks of material into plates and for forming stacks of plates, said method comprising the steps of:
- passing a knife through a block multiple times and severing a plate from the block, followed by a return movement of the knife,
- after severing a number of plates from the block:
- returning the knife to a position under the most recently cut-off plate,
- lifting the knife,
- inserting a removal means under the plate lifted by the knife while simultaneously driving a removal conveyor for transfer of the stack of plates onto the removal means, and
- placing the stack of plates from the removal conveyor onto an auxiliary conveyor.
A method for cutting blocks of material into plates, said method comprising the steps of:
- severing a partial block from the block by horizontal cutting using a knife,
- returning the knife under said partial block,
- lifting the knife,
- inserting a removal means under said partial block, and transport,
- transport of said partial block onto a conveyor band,
- performing horizontal cuts in said partial block for severing a number of plates, said plates forming a stack of plates, and
- processing the stack of plates by performing vertical cuts.
