MUMBAI, India, June 13 -- Intellectual Property India has published a patent application (202517049507 A) filed by Trutzschler Group Se, Monchengladbach, Germany, on May 22, for 'method for detecting foreign bodies in fiber material.'
Inventor(s) include Engels, Guido; and Dovern, Martin.
The application for the patent was published on June 13, under issue no. 24/2025.
According to the abstract released by the Intellectual Property India: "The invention relates to a method for detecting foreign bodies in fiber material (3) which is received in a filling shaft (2) of a preparation machine (1; 100), in particular a spinning preparation machine. The preparation machine (1; 100) has a housing (26) with a housing opening (27), via which the filling shaft (2) is visible from the outside, and an inspection device (30) which closes the housing opening (27) and which comprises a separating element (32) with a transparent monitoring region (39) and at least one camera (54) which has a view into the filling shaft (2) through the monitoring region (39). The method has the following repeating steps: capturing (72) images of the fiber material (3) passing by the monitoring region (39) by means of the at least one camera (54); analyzing (73) the captured images by means of at least one analyzing unit (57) which is connected to the at least one camera (54) and is configured to determine the content of foreign bodies in the fiber material (3) and provide the foreign body content as an output value; comparing (85) the output value with a specified and/or previous starting value; and carrying out an optimization run (92) in which the position or speed of at least one cleaning element (15, 16) for removing waste material from the fiber material (3) is automatically modified if the output value deviates from the starting value, wherein the current waste composition of the separated waste material, comprising foreign bodies and reusable fibers, is determined (80) in a waste section (21) connected downstream of the at least one cleaning element (15, 16) by means of a waste sensor device (22) using at least one optical sensor (23, 24)."
The patent application was internationally filed on Oct. 18, 2023, under International application No.PCT/EP2023/078982.
