Apparatus and a method for aggregating a desired number of articles without individually counting out each article to achieve the desired number. A stream of the articles is discharged into a weigh hopper until substantially a predetermined weight of articles is in the hopper. The number of articles in the hopper is determined from the total weight of the hopper and the weight of a single article. Additional articles are caused to enter the hopper one-by-one until the desired total number of articles is contained in the hopper. The contents of the hopper are then packaged for distribution.

Apparatus and method for dispensing batches of articles

A method and apparatus for counting irregularly-shaped articles. A pair of light sources are provided at a sensing plane through which articles to be counted pass. Each of the light sources emits a light beam that is at an angle to the other light beam, such as an angle of about 90.degree.. Corresponding light sensors are positioned opposite the respective light sources to receive the light signals as the articles pass through the sensing plane. A time division multiplex circuit is provided to alternately operate the light sources, and the outputs from the respective light detectors are summed to provide a unitary signal that is provided to a counter to maintain a count of the number of articles passing through the sensing plane. The system provides combined output signals that are substantially independent of the orientation of the article at the sensing plane.
