Abstract
Devices for stacking sheet-fed paper or cardboard sheets (,) on pallets (,) are known to have a vertically stationary conveyor (,) at a height above the maximum stack level above the floor and a storage platform (,) which can be raised and lowered upon which the stacks are formed. An optical sensor (,) which senses the stack level is arranged at the input side prior to the stacking area to control the lowering of the storage platform (,). According to the invention, at least three optical sensors (,) are disposed below the conveyor level at a slight distance from each other in a vertical line. The maximum vertical distance between the two sensors (,) is 20 mm. By activating any two sensors (,), the drop in height of the sheets (,) can be set depending on the type of sheet and without the need for extensive adjustment upon a change in the type of sheet.
