Blank diecutting machine

Abstract

A machine for diecutting blanks and having a feeding station for sheets, a sheet feeder through the machine for the fed sheets, a sheet diecutting station, a stripping station for free waste cut from the sheets, a blanking and delivery station of the blanks, an evacuation station for waste attached to the blanks and a binder sheet inserting device for inserting binder sheets from a storage pile of binder sheets between the blanks during piling up of the blanks. A feeding compartment receives the storage pile of binder sheets. That compartment occupies a volume situated between the evacuation station of waste attached to the blanks and a machine base. A lifting mechanism lifts the storage pile of binder sheets during insertion of the binder sheets between the piled up blanks.

1 . Machine for diecutting blanks in sheets of paper, cardboard or other sheet material, the machine comprising: 
 a feeding station for the sheets, a sheet feeder for feeding sheets at the station through the machine; a diecutting station operable as the sheet is fed to cut the sheet and create waste, a stripping station for the free waste that has been cut, a blanking and delivery station of the blanks at which the blanks are piled, an evacuation station for waste attached to the blanks, a machine base under the stations of the machine;    a binder sheet inserting device for inserting binder sheets from a storage pile of the binder sheets between successive blanks as the blanks pile up at the delivery station, the inserting device comprising a feeding compartment for receiving the storage pile of binder sheets, the feeding compartment occupying a volume between the evacuation station of waste attached to the blanks and the machine base, and    a lifting mechanism placed and operable for lifting the storage pile of binder sheets during the inserting of the binder sheets between the piled up blanks.    
   
   
       2 . Machine according to  claim 1 , further comprising a housing surrounding the machine, the housing having a transverse wall at a side of the housing downstream in the sheet feeding, a door on the transverse downstream sidewall of the housing and operable to enable access in the housing for positioning of the storage pile of binder sheets in the storage piles in the housing.  
   
   
       3 . Machine according to  claim 2 , wherein the door includes a viewing window.  
   
   
       4 . Machine according to  claim 2 , wherein the door is a safety door operable to cause the machine to stop when opening the door.  
   
   
       5 . Machine according to  claim 1 , wherein the feeding compartment comprises a fixed front stop downstream in the sheet feeding, two movable lateral centering stops at lateral sides of the storage pile, an actuating device comprising two drives for the lateral centering stops, and the drives comprising means for engaging the lateral centering stops and for simultaneously moving the two lateral stops over identical lengths and in the opposite directions from one another.  
   
   
       6 . Machine according to  claim 5 , further comprising a horizontal swivelling shaft, the feeding compartment further comprises a rear stop having a rest position, the rear stop is articulated around a horizontal swivelling shaft; and a detector for detecting swivelling of the rear stop about the swivelling shaft from its rest position.
