Claim 0:
1. 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, including any of plastic granular material or plastic pellets or plastic grains, and
a feeder 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 grain scraper and/or a grain aligner for the bulk material or grain is arranged to scrape off the grains and/or align the grains.
