Abstract
A reciprocating axis of the ejector is born in a non-sliding state by permanent magnets on the reciprocating axis and permanent magnets surrounding the reciprocating axis. The reciprocating axis linearly projects out and retracts by the reciprocating components which cause the reciprocating axis to reciprocate by the driving signals from the driver circuit. A slanted surface is provided at the foremost end of the reciprocating axis. When the granular objects to be ejected flow-in continuously, the projecting-out action takes place correspondingly with the leading granular object to be ejected and, after the following granular object(s) to be ejected has been ejected, the retracting action takes place.
Claims5
A granular object sorting apparatus comprising:
- a transfer means for transferring granular objects to be sorted;
- an illuminating means for irradiating light to said granular objects released from said transfer means;
- a light receiving means for receiving light from the granular object having received irradiating light of said illuminating means, said transfer means, said illuminating means and said light receiving means being arranged at a point along a falling locus of the granular objects released from said transfer means;
- a determination means for determining as to whether each of the granular objects is to be ejected or not based on a received light signal from said light receiving means, and outputting an ejection signal for the object to be ejected;
- a driver circuit for outputting a driving signal based on said ejection signal from said determination means;
- and
- an ejection means for ejecting the granular object to be ejected, said ejection means including a reciprocating axis which is born in a non-sliding state and which linearly projects out or retracts in an axial direction and a reciprocating means for causing the reciprocating axis to retract or project out by said driving signal from said driver circuit, said reciprocating axis having at the foremost end portion thereof a slanted surface inclining towards the projecting direction of the reciprocating axis from the upstream side of the falling locus, said slanted surface being adapted to hit the granular object in the falling locus during the projecting-out operation of the reciprocating axis and said driver circuit being arranged to output the driving signal to the reciprocating means so that, when the granular objects to be ejected by a given ejection means are determined as continuous, the projecting-out operation of the reciprocating axis is caused correspondingly to the leading granular object to be ejected and, after the ejection of the succeeding granular object or objects to be ejected, the retracting operation takes place.
