Claim 15:
16. An apparatus for feeding single grains to one or more processing machines, comprising:
at least one singulator,
a granular material reservoir for a bulk material, and
a feeding device for feeding the singulated bulk material to the injection molding machine,
wherein at least two housing sections are arranged around the singulator to form a closed housing,
wherein the singulator is formed from a singulating disk,
wherein the singulating disk is provided with suction openings distributed over a pitch circle, and the granular material reservoir is arranged on one side of the singulating disk for receiving bulk material and a negative-pressure generating device for generating a negative pressure in a negative-pressure chamber is arranged or connected on an opposite side,
wherein the singulating disk is mounted on a shaft and coupled with a drive, and, via the shaft, the singulating disk is configured to be rotated with the suction openings to receive the bulk material directly against the singulating disk, and to dispense the bulk material, and a seal is configured to seal the rotating singulating disk,
wherein the singulating disk is provided with suction openings as through bores,
wherein the suction opening is smaller than the grain to be transported,
wherein a stirrer or a carry-along is arranged on the singulating disk for receiving the bulk material or on the shaft or one or more load cells for measuring the weight of the bulk material contained are arranged in the region of the granular material reservoir, or wherein the entire apparatus is arranged on load cells or on a weighing device for determining the weight of the bulk material filled or of the grains or of the entire apparatus.
