Abstract

PURPOSE: To sense off error in feeding sheets of paper by a pneumatic attraction type paper feeder device and to allow the unit to stand by, taking the initial position in the sequence of the unit, when any error in feeding is sensed by such an arrangement as sensing the drop of suction pressure for attraction of sheets of paper, i.e. the drop of vacuum.
CONSTITUTION: In this paper feeder device, the leading edge of a sheet of paper attracted by a suction cup 2 is transported to and held by a leading edge suction hole 3a excavated in a rotary drum 3, and the whole sheet is wound round this drum 3, where the trailing edge of the sheet in held by another suction hole 3b. Now, the device is equipped with a pressure switch 6 to sense off the drop of pressure in a vacuum pump 1, and paper feeding condition can be estimated by actuation/deactuation of this pressure switch 6 --- that is to say, actuation of the pressure switch 6 will inform us that any miss-feeding has arisen and we must stop the unit and give an alarm, and replace the unit to the initial position in the sequence of the unit.
