Abstract
The invention relates to a process which enables foreign bodies to be rapidly recognized and filtered out of fibre processing lines. A stream of fibres is inspected by color sensors. If foreign bodies are detected in the flow of fibres, they are blown out by compressed air nozzles (13). The inspection and filtering out can be performed with continuous operation, and purposeful filtering out blows only a few foreign bodies out with the fibres.
Claims13
A process for the recognition and filtering out of differently colored foreign bodies from fibre flocks in processing lines, said process including the steps of:
- continuously transporting the fibres over a measuring distance and past a plurality of color sensors to detect the presence of said in bodies in the flocks;
- and
- compacting the fibres in a converging shaft, one wall of which is formed by a conveyor belt which moves the fibres along and past the color sensors;
- the color sensors being disposed in columns one beside the other.
A process for the recognition and filtering out of differently colored foreign bodies from fibre flocks in processing lines, said process including the steps of:
- continuously transporting the fibres over a measuring distance and past a plurality of color sensors to detect the presence of said foreign bodies in the fibre flocks;
- compacting the fibres in a converging shaft;
- and
- conveying the fibres along the color sensors by a single conveyor belt, the color sensors being disposed in columns one beside the other.
A process for the recognition and filtering out of differently colored foreign bodies from fibre flocks in processing lines, including the step of continuously transporting the fibres over a measuring distance and past a plurality of color sensors to detect the presence of the foreign bodies in the fibre flocks, the color sensors being disposed in columns one beside the other, and
- wherein each of the individual color sensors has its own illumination source incorporated therein for the inspection.
