Abstract
A device for separating a batch of sheets from a pile of sheets and introducing the batch into a conveyor of a machine designed for processing the sheets characterized by a frame having a movable stop member mounted thereon, a unit for moving a pile of sheets so that the end of the pile is adjacent the movable stop, a unit which cooperates with the movable stop and separates a batch of sheets from the one end of the pile and another unit for moving the separated batch of sheets in a second direction parallel to the plane of the sheets in the pile to pass through an opening provided by moving the movable stop to enable introduction of the batch into a conveyor of a machine.
Claims10
A device for separating a batch of sheets from a pile of sheets and introducing the batch into a conveyor of a machine designed for processing said sheets, the device comprising a frame with a fixed stop having a movable stop member mounted in the frame adjacent the fixed stop;
- first means for moving the stop member between a first position aligned with the fixed stop to a second position to create a discharge opening between the fixed stop and the movable stop member;
- second means for moving a pile of sheets in one direction perpendicular to the plane of the sheets with one end of the pile being adjacent said movable stop member;
- means cooperating with the movable stop member being held by said first means in the first position for separating a batch of sheets from said one end of the pile and third means for moving said batch of sheets in a second direction parallel to the plane of the sheets in the pile through the discharge opening for introduction into a conveyor of the machine.
A device for separating a batch of sheets from a pile of sheets and introducing the batch into a conveyor of a machine designed for processing said sheets, the device comprising a frame with a fixed stop having a movable stop member mounted in the frame adjacent the fixed stop;
- means for moving the stop member between a first position aligned with the fixed stop to a second position to create a discharge opening;
- means for moving a pile of sheets in one direction perpendicular to the plane of the sheets with one end of the pile being adjacent said movable stop member, said means for moving a pile of sheets including means for regulating the position of the one end of the pile relative to to stop member;
- means cooperating with the movable stop member in the first position for separating a batch of sheets from said one end of the pile, said means for separating the batch of sheets including a separating member, a movable pile pressing member disposed on each side of the separating member and means for moving said separating member and pressing members with the separating member being moved towards the movable stop member and against the edges of the sheets disposed therebetween to cause a separating and lifting up of a batch of sheets from the pile with the pile pressing members being inserted between the lifted batch and the remaining portion of the pile;
- and means for moving said batch of sheets in a second direction parallel to the plane of the sheets in the pile through the discharge opening for introduction into a conveyor of the machine, said means for moving the batch including at least one batch pusher arranged on each side of the two movable pile pressing members, and drive means for moving said batch pushers.
