Device for separating stacked sheets

Separator of stacked sheets, that being applicable as a means of separating blocks (33) and (33′) of stacked sheets (31), these blocks (33-33′) delimited by corresponding pre-cut lines (32), in order to allow that each sector of these blocks (33) and (33′) should form a cardboard box;

• the separator comprising conveyor belts (3) and (3′) mounted on corresponding moveable frames (2) and (2′), intended to tilt centrally and upwards to obtain the separation, along the pre-cut line (32), of the blocks (33) and (33′), previously placed on both conveyor belts (3) and (3′), with the pre-cut line (32) in correspondence with the central area established between both bands (3) and (3′) in whose central area respective rollers (6) and (6′) are mounted, that, in combination with external rollers (5) and (5′) and other tensing and lower rollers (7), form the means of support and movement for the conveyor belts (3) and (3′), driven by corresponding traction rollers (34) and (34′) set up between the tensing rollers (7) and (7′);
• with the particularity that beneath the internal rollers (6-6′) and centrally, cylinders (28) have been provided, whose activation produces the rise and corresponding upwards pivoting of the mobile frames (2) and (2′) and with them of the conveyor belts (3) and (3′), as well as of the corresponding interior rollers (6) and (6′);
• the external rollers (5-5′) remaining static.
