Xrs inspection and sorting of plastic containing objects progressing on production line

A control system for controlling X-Ray-Spectroscopy (XRS) inspection of objects, the control system being a computer system, which is connected to a computer network to communicate, via said network, with a plurality of XRS inspection stations at multiple production lines, and is in data communication with a central database manager, the control system being configured and operable to carry out the following:

• in response to input data indicative of an XRS inspection data piece of an object in association with identification data of said object, utilizing pre-stored data in a central database for analyzing the XRS inspection data comprising data indicative of an XRS signature identified by a certain XRS inspection system with respect to marking embedded in said object, and determining object status data with respect to said object, based on one or more conditions of plastic material composition in the object derived from said data indicative of the XRS signature;
• communicating the object status data to the respective XRS station;
• and based on analysis of XRS inspection data pieces of related objects provided from more than one XRS inspection stations, optimizing data in the database.

An X-Ray-Spectroscopy (XRS) inspection method for inspecting objects progressing on a production line, the method comprising:

• applying one or more XRS inspection sessions to the object passing through an inspection region defined by an XRS inspection station of the production line and generating XRS inspection data piece for said object, wherein the XRS inspection session comprises exciting at least a portion of the object by X-Ray or Gamma-Ray radiation and detecting a response of said at least portion of the object to the exciting radiation comprising data indicative of an XRS signature of marking embedded in plastic material composition of the object, said data indicative of the XRS signature being informative of one or more conditions of plastic material composition in the object;
• based on the XRS inspection data piece, determining object status data, and recording said object status data in association with identification data of the respective object;
• and based on the recorded object status data, generating sorting data for use at a sorting station of the production line.
