Abstract
PURPOSE: To change the suction force of a suction cup in a pneumatic attraction type paper feeder device simply and securely by selecting a switch merely in accordance with the type of paper.
CONSTITUTION: To change the suction force of a suction cup 20 according to the type of paper-for example 110kg, 70kg, 55kg-paper three air passage for those three different types and an air passage for adjustment for any other type of paper are interposed between a vacuum pump 10 and the suction cup 20. In these passages, solenoid operated valves 301W304 to open and close the passages and regulating valves 401W404 for adjustment of suction force are installed. Solenoid operated valves 301W304 shall be so arranged that they can be turned on and off selectively by switches SW1WSW4. According to this arrangement, attraction of a sheet can be made with the optimum suction force by operating one of the switches SW1WSW4 in accordance with the type of paper, that will well ensure a reliable feed of sheets of paper.
