Simple connection to a PLC via Ethernet/IP and storage of inspection images on a remote FTP server permit industry-oriented integration in the particular control environment of a packaging machine.
An illuminating solution for correct product packaging and reliable processes
Protection against counterfeits, design optimization, differentiability in the packaging procedure – there are various reasons why packaging and its contents are provided with fluorescent marks that are invisible to the human eye. At the same time, many automated processes call for the objects or marks to be detected regardless of position, orientation and size within the extended area of, for example, a conveyor belt. The Inspector I40 LUT has been specially designed for such 2D tasks. During the inspection, the vision sensor emits invisible short-wave UV light. If invisible luminophores are present within the sensor’s field of view, the UV light excites these fluorescent materials and they light up. The resultant long-wave light in the visible spectrum is detected by the Inspector I40 LUT with image capture, and inspected for the particular product feature. The vision sensor is capable of evaluating the pattern, frequency and differences between luminophore marks within a test window, and can therefore provide statements on quality or for differentiation purposes.
Solves the most varied of inspection tasks
The Inspector I40 LUT offers a high level of flexibility for the solution of the most varied of tasks. Inspection tasks can be individually set up and adapted with the integrated package of software tools. Whereby up to 32 reference objects can be stored, allowing the device to react to frequent product changes – and the corresponding alterations in the inspection scenarios – using a simple switching process, without impairing the availability of the packaging plant. In this way, the Inspector I40 LUT can very flexibly and reliably implement packaging-related requirements regarding quality, security and traceability.
Is the package insert present?
Paper generally contains so-called natural luminophores. When these are excited with UV light they, too, emit light in the visible spectrum. This effect is familiar from white shirts or blouses illuminated with a black-light bulb, e.g. in discotheques. In exactly the same way, the Inspector I40 LUT can examine whether the package insert is present in packets that are still open. Optional color filters can further enhance the effect for better inspection.
