LABELLING 41 PETplanet Insider Vol. 21 No. 05/20 www.petpla.net LABELLING 41 ing heads. So in case the same label is applied by different heads, we can easily redirect the offset value to the specific dispensing head.” This feature secures, that the right head is adjusted with its cor- responding offset value. This solution can be implemented in cooperation with both linear and rotary labelers. Intravis has already been using such applications, for example at a German global player since 2018. Prevention of product refinement: With this type of application, the whole labelling process is distributed over several sta- tions. At a first station, for example, a front label is attached by a dispensing head, at a second station a back label is applied and at a third station a code is engraved. An inspection unit can be integrated after each of the stations to check that all important parameters are correct. If one of the first two inspection stations detects an intolerable deviation, the further finishing steps (i.e. station two and/or three) are deactivated for the defective object. This prevents further processing of a faulty object and simplifies the recycling process of it and saves material. Correction of object orientation: While in the first two applications the inspection station is integrated after each process- ing step, this application is used before the actual labelling process. The inspec- tion unit determines the orientation of an object with regard to the necessary object orientation for the labeller or printer. If a faulty orientation is detected, further pro- cessing at subsequent labelling stations is de-activated and the object is sorted out for reutilisation. Why an inspection system? The most important advantage is obvi- ous: to avoid the further processing of already faulty objects. The earlier a defec- tive product is recognised in the produc- tion process, the less effort and material is invested in it. Producing faulty products can be avoided if the label dispensing head is permanently and automatically readjusted as described above. All this happens without any manual interven- tion. Thus, employees have more time to accomplish other tasks in the company. With most of these applications imple- mented in the recent years, Intravis shows that vision inspection systems for labels as well as for closures, preforms, bottles and containers are more than just sorting out units. www.intravis.de www.sacmi.com Product design Product development Product validation Industrial production plant Process & quality control On-site and start-up assistance After-sales and Customer service SACMI 4.0 THE COMPLETE CLOSURE, PREFORM AND CONTAINER SOLUTION FOR YOUR SMART FACTORY ENDLESS INNOVATION SINCE 1919
