  • Recording of trash in a fiber preparation system
    Patent number: 11976388
    Abstract: A method and associated device and system are provided for recording trash in a fiber preparation system having a plurality of cleaning points and a transport line that is connected to the cleaning points and is guided into a central container connected to a negative pressure source for generating transport air. The trash is suctioned from each cleaning point through the transport line with the transport air to the central container and is feed separately from each cleaning point to the central container. In the central container, the trash is separated from the transport air and transferred into a scale for weighing. With the trash located on the scale, an optical recording of the trash is made with a camera directed to an interior of the scale.

  • FIBER PREPARATION MACHINE
    Publication number: 20220042212
    Abstract: A fiber preparation machine for processing fiber material includes a store or filling chute for storing the fiber material before or after processing. A camera is directed into an interior of the store or filling chute, the camera having an optical axis oriented at an angle (?) with respect to a vertical axis that is perpendicular to a surface of the fiber material in a range of plus 30 degrees to minus 30 degrees. The camera has a resolution for detecting a particle having an extension of 0.1 mm2 on the surface of the fiber material.
