Refilling Device for a Stacking Magazine with Metal Sheets

Abstract

A refilling device on a stacking magazine (2) comprises a refilling magazine (18) which is disposed above the stacking magazine and has a rotatably drivable shaft (10) on each of two sides of the refilling magazine, the shafts together forming a support for a stack (11), and at least one controllably activatable air nozzle, by way of which air can be blown into the refilling magazine in such a way that metal sheets on the bottom side of the stack (11) can be bent by the air supply in the direction of the stacking magazine.

What is claimed is: 
     
         1 - 17 . (canceled) 
     
     
         18 . A refilling device on a stacking magazine ( 2 ), comprising a refilling magazine ( 18 ) which is disposed above the stacking magazine, wherein the stacking magazine ( 2 ) has a rotatably drivable shaft ( 10 ) on each of two sides of the refilling magazine, the shafts together forming a support for a stack ( 11 ), and at least one controllably activatable air nozzle, by way of which air can be blown into the refilling magazine in such a way that metal sheets on the bottom side of the stack ( 11 ) can be bent by the air supply in the direction of the stacking magazine. 
     
     
         19 . The refilling device according to  claim 18 , wherein the shafts ( 10 ) are actuated by a drive means, particularly wherein the drive means comprises two drive motors ( 30 ). 
     
     
         20 . The refilling device according to  claim 18 , wherein the refilling device comprises a filling level sensor ( 31 ) in the stacking magazine ( 2 ), wherein a low filling level is detectable with the filling level sensor ( 31 ) and can be reported to a controller of a destacking device or to an entire arrangement of destacker and rounding device and welding machine, wherein the refilling device can then be activated by means of the controller. 
     
     
         21 . The refilling device according to  claim 20 , wherein the filling level sensor ( 31 ) is an optical, light-barrier-based filling level sensor, or an electrical, particularly inductive, filling level sensor.
