Abstract
A leaves counting machine comprising a rotor having a plurality of suction heads arranged on a rotary disc. Leaves are counted by drawing and turning over them one by one by the suction heads in the course of rotation of the rotor. Changes in a suction pressure during the suction of leaves onto the suction heads are detected by a pressure transducer and the counting is executed by the use of pulses detected by the pressure transducer.
Claims2
A counting method in a leaves counting machine wherein a rotor has a plurality of suction heads arranged on a rotary disc at equal intervals and wherein leaves are counted by drawing and turning the leaves over one by one by the suction heads in the course of rotation of the rotor, said method comprising detecting changes in suction pressure during the suction of the leaves against the suction heads by a pressure transducer, converting the change in suction pressure into an electrical pulse by said transducer, feeding the pulses from the transducer through an amplifier and a level discriminator circuit and counting said pulses.
