Filed: 1963-08-07
Abstract: 967,058. Feeding sheets. G. SPIESS. Aug. 7, 1963 [Aug. 8, 1962], No. 31148/63. Heading B6B. A telescopic, sheet-lifting sucker device for separating sheets from the top of a pile 6 comprises a suction cup 5 on a hollow piston 4 which is guided for vertical movements in a cylinder 3, the latter also constituting a hollow piston which is vertically movable in a bore 1 of a fixed casing 2. Both pistons 3, 4 have intercommunicating central bores, the piston 3 being urged downwardly by a strong compression spring 8, and the piston 4 being acted upon by a weaker spring 9. The top of the bore 1 is connected through a duct 10 to a suction conduit 11. When the suction cup 5 rests on the pile 6 and is sealed, the piston 4 first moves upwardly with the top sheet of the pile, and then the two pistons 4, 3 move together upwardly until a lateral stop 12 on the piston 3 abuts a stem 13 of a non-return valve 14. In this position, the valve 14 is raised to allow compressed air to issue from conduits 17, 18 to float the raised sheet. When the sheet is removed from the cup 5, the springs urge the pistons downwardly, the piston 3 being the first to reach the bottom due to the stronger spring 8, and the piston 4 then falls gently on to the top of the pile 6. A stop pin 20 on the free end of a leaf spring 22 secured by a screw 21 to the piston 3, engages a vertical groove 19 in the piston 4 to retain the latter and prevent rotation thereof; a similar arrangement is provided for the piston 3. The end wall 7 of the bore 1 has a small air inlet aperture 23.
