Multiple insert delivery systems and methods

A delivery system, comprising:

• a frame;
• a plurality of hoppers attachable to the frame in a vertically spaced apart arrangement, wherein the hoppers are each configured to hold a plurality of sheet-like materials;
• at least one upper belt movably coupled to the frame, wherein the belt is configured to move sheet-like materials downward from the hoppers;
• at least one contact roller disposed below each hopper;
• at least one suction apparatus that is associated with each hopper, wherein the suction apparatus is movable toward and away from the hopper to remove the sheet-like materials from each hopper;
• and
• a guide that is configured to hold one of the sheet-like materials to the upper belt as the sheet-like material moves toward the contact roller.

A sheet-like material detection system comprising:

• a frame;
• at least one belt that is configured to move sheet-like materials;
• at least one roller disposed over the belt that is configured to roll over a sheet-like material moved by the belt, wherein the roller is coupled to an axle that is pivotally coupled to the frame;
• an arm that is coupled to the axle;
• a potentiometer in contact with the arm, wherein the potentiometer is configured to produce an electrical signal that is related to the amount of movement of the arm that is turn is related to the amount of movement of the roller when one or more sheet-like materials is beneath the roller.

A method for moving sheet-like materials, the method comprising:

• coupling a plurality of hoppers to a frame in a vertically spaced apart arrangement, wherein the hoppers each hold a plurality of sheet-like materials;
• moving one of the sheet-like materials from one of the hoppers with a suction apparatus;
• moving the suction apparatus and the sheet-like material downward until the sheet-like material is grabbed between at least one upper belt that is movably coupled to the frame and at least one contact roller that is disposed below the hopper;
• and
• moving the sheet-like material downward with the upper belt.
