Abstract

1371950 Feeding sheets INTERNATIONAL BUSINESS MACHINES CORP 2 June 1972 [23 June 1971] 25809/72 Heading B8R A picker foot 16 for separating sheets from a pile 12 is connected by a bellows 18 to a shaft 11, and carries a roller 22 which rides on a cam surface 24 in a frame 54, the cam surface being formed with a virtual slot 26 at its lowest point. The roller is urged against the cam surface by a spring. As the picker foot is rotated by the shaft, a sheet is carried to a station 14 where it is stripped from the foot, which returns to its initial position. The foot is connected to a vacuum source through a conduit 20. In its initial position, the foot is urged downwards, as permitted by the slot 26, towards the sheet pile, by gravity and the spring, the roller rotating an arm 30 about the pivot of a shaft 48, thereby rotating the shaft through a one-way clutch. When the picker comes within a predetermined distance from the pile, the resulting alteration in air pressure in the conduit 20 is sensed by a detector which causes an electric brake to be applied to the shaft 48 to stop further downward movement of the picker. A cam 58 on a shaft 56 rotated by a motor 57 thereafter swings the arm 30 to save the picker until the roller is clear of the slot, whereafter a further cam 59 on the shaft 56 disconnects the electric brake and closes a spring clutch 25 to cause the rotation of the shaft 11. Raising of the picker before the brake is disconnected is allowed by the one-way clutch. A sheet is attracted to the foot by suction when the foot is in its lowest position. Air flowing into the foot is utilized to blow against the side of the pile to loosen the upper sheets, and this flow of air is stopped when a sheet engages the foot. Brushes 64 prevent double feed.
