In the pharmaceutical industry, tampon print has been the way of printing on products. In all industries, and in the pharmaceutical industry in particular, there is a strong trend towards smaller batch sizes, higher flexibility, higher demands and fast switching between different products.
By using a rather new concept of linear movers in the form of Beckhoff’s XTS system in cooperation with Plasma pretreatment, HAPA Redcube plus printer, UV hardner and vision inspection we were able to develop a flexible solution that is capable of handling capacities from 0–220 incoming products per minute with a footprint that is much smaller than the old type of Tampon print, with the same print quality. The Digital Pad Printer also offers quicker turnaround time between jobs, less maintenance and lower overhead costs.
As always, the conceptualization started with brainstorming. The ideas were quickly directed at the rather new concept of using linear movers that could be controlled individually or synchronized together as needed on a common track.
The XTS system is an excellent basis for flexible solutions
After evaluating the products available, it was decided to use the Beckhoff XTS system. As in most cases involving Graniten solutions. Together with HAPA´s Redcube plus printer head, Plasma pretreatment, UV hardener and vision system, we had the foundation to start developing our Inline Digital Pad Printer.
The key challenge during the development of this machinery solution was to make the XTS system capable of handling a considerably higher payload than it was initially designed for. By developing a patented guide-rail system, Graniten could overcome this, thereby widening the potential uses of the XTS product. By using XTS technology, it is possible to disconnect the interdependency of the various machinery modules and it also enables the machines to be more compact.
By modifying minor components and software, the solution is capable of handling capacities from 0–220 incoming products per minute with a small footprint. The machine design enables the operator to perform line clearance and change format in a matter of minutes.
