Abstract
An equipment of accumulation of sheets forms a stack of sheets on an accumulation plane by means of driving belts and diverters arranged along the path of the sheets and jump on the accumulation plane. The height of the jump is modified by shifting vertically the accumulation plane with respect to the diverters according to number and/or thickness of the sheets. The diverters can be shifted according to the length of the sheets to be accumulated, while a series of arrest lugs delimits at the rear the area of collection of the sheets and a forwarding mechanism with a pair of output rollers forwards the stack of accumulated sheets when the lugs are released.
Claims11
A sheet accumulating equipment comprising an accumulation plane for sheets entering along a feeding direction, a plurality of driving belts of elongated shape, with respective lower branches positioned in parallel a little above the accumulation plane and ramp members arranged along the path of the sheets and lifting the sheets with engagement with said lower branches and wherein said belts are driven for dragging the lifted sheets with the lower branches and depositing the sheets, by jump, on the accumulation plane or on sheets in accumulation, said accumulating equipment further comprising
- a suspension group for the accumulation plane, a shifting command mechanism and a carriage of support for said ramp members, wherein
- said suspension group is provided for allowing a vertical shifting of the accumulation plane with respect to the ramp members so as to modify the height of the jump, and
- said shifting command mechanism can be actuated for the vertical shifting of the accumulation plane by adapting the height of the jump according to number and thickness of the accumulated sheets,
- said accumulation plane defines a plurality of longitudinal slots, while the ramp members are mounted on said carriage and are partially housed in said longitudinal slots;
- and
- wherein said carriage is longitudinally shiftable for limiting, by means of the ramp members, a longitudinal extension of a sheet gathering area functionally to the length of the sheets to be accumulated.
