Patent number: 11724286Abstract: An apparatus for detecting matter comprises bulk feeding means configured for feeding a plurality of objects into a detecting region; at least one light source having a focusing element and being configured for illuminating at least one object moving in an object plane in the detecting region; and a first light-analyzing apparatus arranged to sense light that has been transmitted through the object. In the associated method, the object is caused to move in the plane and the object is illuminated with incident light. Light that has been transmitted through the object and is falling in a measuring plane is detected, and an object-specific parameter based on the detected transmitted light is determined.Type: GrantFiled: November 3, 2014Date of Patent: August 15, 2023Assignee: TOMRA SORTING NVInventors: Dirk Balthasar, Tobias Hartmann, John McGloughlin, Douglas Alexander Reid

Publication number: 20230213443Abstract: An apparatus for detecting matter including: a light source arrangement adapted to emit a first and a second set of light beams towards a first detection zone through which the matter is provided. A spectroscopy system adapted to receive and analyse light which is reflected and/or scattered by matter in the first detection zone. A laser triangulation system including, a laser arrangement adapted to emit a line of laser light towards a second detection zone. A camera-based sensor arrangement configured to receive and analyse light which is reflected and/or scattered by matter in the second detection zone. The received light of the spectroscopy system completely or partially intersects the received light of the camera-based sensor arrangement and/or the line of laser light.Type: ApplicationFiled: May 4, 2021Publication date: July 6, 2023Applicant: Tomra Sorting GmbHInventors: Dirk BALTHASAR, Michael MAYER, Patrick STURM, Tobias TÜCKMANTEL

Publication number: 20230011383Abstract: A bulk sorting system for sorting objects in bulk is provided. The bulk sorting system includes: at least one radiation source arranged to radiate the objects, at least one optical sensor arranged to capture reflected radiation of the objects and acquire the reflected radiation as multi- or hyperspectral data; a processing circuit configured to analyze the reflected radiation of the objects by inputting the multi- or hyperspectral data into a convolutional neural network (CNN) with at least two convolutional layers in order to either detect and classify the objects in the multi- or hyperspectral data and/or semantically segment the multi- or hyperspectral data; and a mechanical sorter configured to sort the objects according to their classification and/or segmentation using the analysis of the processing circuit such that different overlapping and/or stacked objects are separated or treated as a single group of objects.Type: ApplicationFiled: November 4, 2020Publication date: January 12, 2023Applicant: Tomra Sorting GmbHInventors: Dirk BALTHASAR, Daniel BENDER, Frank SCHMITT

Patent number: 9594040Abstract: A method for analyzing objects depending on their electromagnetic properties. The method including the steps of conveying the objects to be analyzed on a conveyer belt; scanning the electromagnetic properties of the objects and the conveyer belt by an electromagnetic sensor, wherein the electromagnetic properties of the conveyer belt are dependent on metallic contaminants which are stuck in the conveyer belt; generating belt properties data representing the electromagnetic properties of the conveyer belt, and analyzing the objects according to the scanned electromagnetic properties and the belt properties data. This has the benefits that the electromagnetic properties of the conveyer belt are considered when distinguishing between metallic and non-metallic objects which have to be sorted. This way, the objects which got stuck in the conveyer belt over time, may influence a sorting less, which may improve sorting results. Further, an apparatus for executing such a method.Type: GrantFiled: August 16, 2013Date of Patent: March 14, 2017Assignee: TOMRA SORTING ASInventors: Dirk Balthasar, Thomas Erdmann, Volker Rehrmann, Stefan Jürgensen, Slah Gharbi
