Can sorting method and apparatus
摘要:
An article or can sorting apparatus for separating articles having a recycle value from articles having no recycle value is defined by an annular article supporting surface positioned at about 45 degrees to horizontal, a cylindrical wall positioned in relation to the surface to define an article processing chamber, a feed hopper into which a plurality of the articles are deposited for feeding into the chamber, and an article conveying disc or wheel positioned in parallel relation to the surface and having a plurality of outwardly extending article pusher arms for separating the articles, such as discarded beverage cans, from the plurality of articles and conveying the articles one at a time about the annular surface to a material discriminator and a weight scale and toward an accept door or a reject door. The material discriminator or metal detector, the scale, and the accept and reject doors form segments of the article conveying surface. The apparatus is preferably controlled by a computer; and on the basis of the material and weight determinations, each article is either accepted for recycling or rejected and returned to a customer. The number of accepted articles is counted, and a printer is provided for printing out a tape documenting the money payout due the customer for the recycled articles.
