Ejection System for Laminated Material Stacker

An ejection system for laminated material stackers that is configured to receive said laminates in an initial position, move them and release them in a final position, the ejection system comprising:

• a frame with transverse ends and longitudinal ends, the frame including vacuum assemblies movably mounted on the frame via splined shafts;
• the vacuum assemblies comprising at least vacuum boxes and perforated belts which are conveyor belts with a plurality of perforations to allow the vacuum generated in the vacuum boxes to be applied to the laminates to be moved;
• the vacuum assemblies movable on the splined shafts, adapted to be moving towards or away from each other;
• retractable guides mounted on the vacuum assemblies, wherein the retractable guides can be moved between a retracted position and a guided position, in which the retractable guides have moved vertically in a direction perpendicular to the longitudinal direction of the vacuum assemblies, moving away from the frame;
• and
• a position adjustment mechanism configured to adapt the position of the vacuum assemblies in the transverse direction of the frame, wherein the mechanism comprises at least one pair of spindles, each having a first end and a second end, and wherein each spindle is threaded in a different direction, clockwise and anti-clockwise respectively;
• wherein the vacuum assemblies engage with the spindles by nuts such that the rotation of the spindles causes the longitudinal movement of the vacuum assemblies.
