High capacity compiler with vertically adjustable sheet discharge and acquire means

An apparatus for compiling a plurality of sheets received from a printing machine to form a stack thereof, comprising:

• means for acquiring and discharging sheets, said acquiring and discharging means comprises a first plurality of rotatable driven members and a second plurality of rotatable idler members in frictional contact with said driven members so as to form a sheet discharge drive nip;
• sheet compiling means disposed adjacent to said acquiring and discharging means for receiving sheets from said acquiring and discharging means;
• means for determining the stack height in said sheet compiling means;
• means, responsive to said height detecting means, for moving said acquiring and discharging means relative to said sheet compiling means;
• and
• means, proximately disposed to said sheet compiling means, for longitudinal registration of the sheets received from said acquiring and discharging means, said longitudinal registration means comprising a plurality of members coaxially aligned with said rotatable members and a plurality of endless belts partially entrained around said members with the lower outer circumference of said belts being in frictional contact with the topmost discharged sheet in said compiling means.

• a vertically adjustable tray, positioned adjacent to said acquiring and discharging means disposed to receive sheets from said acquiring and discharging means, said tray inclined so as to oppose the direction of sheet discharge, wherein said tray further includes an end registration edge adjacent to said acquiring and discharging means;
• means for determining the stack height in said tray;
• means, responsive to said determining means, for moving said acquiring and discharging means relative to said tray;
• and
• means, proximately disposed to said tray, for longitudinal registration of the sheets received from said acquiring and discharging means, said longitudinal registration means comprising a plurality of members coaxially aligned with said rotatable members and a plurality of endless belts partially entrained around said members with the lower outer circumference of said belts being in frictional contact with the topmost discharged sheet in said compiling means.

• means, responsive to said height detecting means, for moving said acquiring and discharging means relative to said sheet compiling means;
• and
• means for lateral registration of each of the received sheets in the stack in said compiling means, wherein said lateral registration means comprises a laterally movable guide for positioning each sheet of the stack against said lateral registration edge so that the compiled stack of sheets is fully registered, wherein said laterally movable guide further comprises a vertical member, and an upwardly flared member wherein said upwardly flared member has an upturned surface which is highest at a point adjacent said vertical member.
