METHOD AND ARRANGEMENT FOR WORKING PROFILE BLANKS

摘要

A method and an arrangement for finishing a number of different pre-treated profile blanks, such as T-bars or the like, at a finishing station provided with a transport means for transporting the profile blanks, positioning means for profile blanks, imaging means, at least one finishing robot and a computer-based control system. The method includes the following operations accomplished at the finishing station: each profile blank is introduced into the finishing station by means of the transport means and positioned into a certain preknown position; a selected field of view of the profile blank is photographed by means of the imaging means; the basic form and essential dimensions of the profile blank are detected from the picture; certain forms, taught to the control system and deviating from a regular profile blank, especially lead-through openings, lightening holes and yield cuts, are searched and identified from the picture, on the basis of which a classification of the profile blank is achieved, the control system determining the further operations to be carried out in each case on the basis of the classification; the control system controls the finishing robot to accomplish one or more of the following operations: milling, grinding and/or cutting the profile blank, or the profile blank is moved directly to the next step; the profile blank is moved one field of view forward in the finishing station.
