Device for stacking sheets, especially sheets of paper or cardboard transported by a stream feeder, onto pallets

Abstract

In order to stack sheets of paper or cardboard ( 1 1) transported by a stream feeder onto pallets ( 4 ), devices arm known which comprise a stacking platform ( 5 ) which can be raised and lowered, and on which the piles ( 3 ) are formed. During the stacking process, the longitudinal edge of a sheet ( 1 ) is guided by a separating plate ( 12 ) which is suspended on a holding element fixed in the machine frame, and is connected to a vibrator ( 13 ) in the form of a shaking element. According to the invention, in order to improve the shaking effect of the separating plate ( 12 ), a holding plate ( 18 ) is fixed, by means of rubber elements ( 19 ), to the holding element fixed in the machine frame, in such a way that it is decoupled from vibrations, the separating plate ( 12 ) and vibrator ( 13 ) being suspended from the holding plate in a rigid manner.

1 . A device for stacking sheets transported by a stream feeders onto pallets, the device comprising: 
 (a) a stacking platform capable of being raised or lowered on which a stack of sheets is formed, and    (b) at least one separating plate capable of guiding the longitudinal edges of a sheet during the stacking, the plate being suspended on a holder attached to a machine frame and and attached to a shaking element,    wherein the holder comprises a holding plate attached to the machine frame via rubber elements so as to be vibration-uncoupled and wherein the separating plate and shaking element are rigidly suspended.    
   
   
       2 . The device of  1 , wherein the separating plate is detachably attached to the holding plate.  
   
   
       3 . The device of  1 , wherein the holder comprises a holding plate mounted in the machine frame and the holding plate is capable of being raised and lowered.  
   
   
       4 . The device of  3 , wherein an ejection roll and a separating shoe are additionally attached to the holding plate.  
   
   
       5 . The device of  claim 1 , wherein the shaking element is a vibrator.
