International Classification:

G01N 2164

US Classification:

356 73, 356317, 356417, 2504611, 250223 R, 2505594, 209577

Abstract:

Apparatus and methods are provided for sensing the presence of bright white paper on a conveyor of a paper sorting system. The conveyor is constantly illuminated with ultraviolet light. When bright white paper is present in the inspection zone of the conveyor, it will re-radiate fluorescent light energy as a result of the ultraviolet light. Periodically, the inspection zone of the conveyor is illuminated with a second light source in the visible light spectrum. Light is collected from the inspection zone of the conveyor, including reflected light from the secondary source and including emitted fluorescent light energy as a result of the ultraviolet light falling on bright white paper. Periodically a microprocessor associated with the sensor senses reflected light from the second source to determine whether any object if present on the conveyor. The microprocessor then senses the level of fluorescent light energy being emitted from any object on the conveyor. The system determines first whether any object is present on the conveyor, as a result of the reflected secondary light, and then determines whether that object is bright white paper depending upon the measured level of emitted fluorescent light energy.

International Classification:

B07B 400

US Classification:

209137

Abstract:

An apparatus and method for reducing the circling upward movement of a product such as waste paper entrained in a carrier stream. The invention includes a product rake placed within a discharge chute to capture and direct product within the product flow. A further aspect of the invention includes a relief valve integrated into the discharge chute to alleviate pressure in the discharge chute and allow excess air to be relieved from the discharge chute to control the product flow.

International Classification:

US Classification:

356417, 209577, 2504591, 2504611

Abstract:

A method is provided for sorting white paper from a stream of paper wherein the concentration of white paper is less than the concentration of non-white paper. The method includes identifying the white paper by detecting the presence of an optical characteristic of the white paper as the stream of paper is passed by a sensor. Then the white paper is ejected from the stream of paper by controlling one or more actuators directed against the white paper, and thereby separating the white paper from the non-white paper. The method is particularly applicable to the sorting of white paper during curbside recycling.
