Abstract
The method involves measuring data of a sheet material first being detected by means of a sensor, the sensor then deriving one or more measuring results from the data. Using a sorting tree a sorting class for the sheet material is derived from the measuring results of the sheet material. In each sorting node of the sorting tree a domain is fixed for at least one measuring result. The domains of a measuring result in a sorting node are selected so that they are either a subdomain or equal to the domain of the corresponding measuring result of the assigned, higher sorting node. The sheet material is transported to a destination in accordance with the derived sorting class for the sheet material.
Claims38
A method for processing sheet material, comprising the steps of:
- detecting measuring data by means of at least one sensor;
- deriving measuring results from the detected measuring data, and
- deriving a sorting class for the sheet material from the measuring results,
- wherein the step of deriving the sorting class for the sheet material comprises the step of locating a sorting node in a sorting tree in which all of said measuring results are within a predetermined ranges of values, said predetermined ranges being hereinafter referred to as domains,
- wherein said sorting tree includes a plurality of sorting nodes, one of said sorting nodes being an uppermost sorting node and all other ones of said sorting nodes being directly connected to one upper node and at least one lower node to form said sorting tree, said uppermost sorting node forming a highest level of the sorting tree, sorting nodes in a lower level of the sorting tree having a common number of sorting nodes between said uppermost sorting node and the sorting nodes in the lower level, sorting nodes between one of the sorting nodes in a lower level and the uppermost sorting node being hereinafter referred to as higher sorting nodes assigned to the sorting node in the lower level, and a lowest level of the sorting tree having a greatest number of nodes between the uppermost sorting node and the sorting nodes of the lower level, and
- wherein said sorting tree has the following characteristics:
- a domain is fixed at least for one of said measuring results in each said sorting node of the sorting tree,
- for said domain of said one of said measuring results in each said sorting node of the sorting tree other than the uppermost sorting node of the sorting tree, a corresponding domain of said one of said measuring results is present in a higher sorting node assigned to each said sorting node, and
- the domain of said one of said measuring results in each said sorting node of the sorting tree other than the uppermost sorting node is a subdomain or equal to the domain of the corresponding measuring result of the higher sorting node assigned to each said sorting node.
