1. A device for separating and counting a pre-determined quantity of discrete objects, said device comprising:
- a feed tray defining an axis extending between an inlet portion and a discharge portion of the tray, the tray including at least one guide path extending along the axis for the passage and singularization of objects, the guide path including a plurality of segments, each of the segments defining a direction of movement along the axis, wherein the direction defined by at least some of the segments is oriented at an angle with respect to the axis, the angle becoming decreasingly oblique toward the outlet portion of the tray;
first means for advancing objects along the guide path from the inlet portion to the discharge portion of the tray, the guide path effecting a singularization of the objects as the objects are advanced thereon;
second means for counting the quantity of singularized objects received at the discharge portion of the tray;
third means for interrupting the advancement of objects along the guide path when the quantity of objects counted equals the predetermined quantity, andcontrol means connected to the second and third means for receiving data from the second means corresponding to the quantity of objects counted and for activating the third means to interrupt the advancement of objects when the data received corresponds to the predetermined quantity.

18. An apparatus for packaging a predetermined quantity of objets, said apparatus comprising:
-
a feed tray defining an axis extending between an inlet portion and a discharge portion of the tray, the tray including at least one guide path for the passage and singularization of objects, the guide path including a plurality of reversely arcuate segments, said segments increasing in radius from the inlet portion to the discharge portion of the tray; first means for advancing objects along the guide paths from the inlet portion to the discharge portion of the tray, the guide paths effecting a singularization of the objects as the objects are advanced thereon; second means for counting the quantity of singularized objects received at the discharge portion of the tray;
the second means including a camera for imaging objects, an optical sensor for registering the image as a pixel array, and a processor for converting the registered image into data;third means for interrupting the advancement of objects along the guide paths when the quantity of objects counted equals the predetermined quantity, the third means comprising a plurality of gates, each one of the gates associated with a respective one of the plurality of guide paths and movable between an open position wherein objects advance along the guide path and a closed position wherein the advancement of objects along the guide path is interrupted; control means connected to the second and third means for receiving data from the processor corresponding to the quantity of objects counted and for actuating the gate associated with a respective one of the guide paths to interrupt the advancement of objects along that path when the data received corresponds to the predetermined quantity; means for transferring objects from the discharge portion of the tray to a container to fill the container with the predetermined quantity of objects, and a conveyor for delivering at least one empty container to a fill position for receiving the predetermined quantity of objects from the transfer means, and for removing the filled container from the fill position.
