Title: Dierk Schroder: Innovator in Tobacco Processing Technology
Introduction
Dierk Schroder is a notable inventor based in Hamburg, Germany. He has made significant contributions to the tobacco processing industry, holding a total of 5 patents. His innovative approaches have enhanced the efficiency and accuracy of measuring and weighing rod-shaped articles in this sector.
Latest Patents
Schroder's latest patents include a method and apparatus for measuring the diameters of rod-shaped articles. This invention allows for the precise measurement of successive articles as they advance sideways on a rotary drum-shaped conveyor. The articles are rotated about their longitudinal axes due to frictional engagement with a rolling member. The system utilizes a laser beam, which is interrupted by the rotating articles, to ascertain their diameters. The intercepted radiation is monitored by a video camera, generating electric signals that are processed to determine the diameters of the articles.
Another significant patent involves a method and apparatus for determining the weight of rod-shaped articles. In this invention, the articles are conveyed along an arcuate path and urged to impinge upon sensors under centrifugal force. The sensors transmit signals to transducers, which convert these signals into data denoting the actual weight of the tested articles. This technology can utilize piezoelectric transducers or extensometers for accurate measurements.
