Seal Film Printing Machine
Travtec Packaging Engineering started developing a new high performance hygienic
seal film printing machine for a major medical device company, it knew that
precision linear indexing would be the key to success, so called in automation
components specialists Hoerbiger-Origa for consultation.
with Travtec to develop a printer that could traverse back and forth across a
moving web of clear film, applying vital consumer information and branding just
before the film seals containers prior to lidding.
The printing on the film
had to be positionally accurate relative to the container and timed to the
sequence control of the overall machine. As
the containers index through a filling station with typically 5-10 filling
heads, the printer is required to traverse with a demanding intermittent motion
cycle at a repeatability of 0.1mm, and this suggested that a servo driven electric linear
actuator would be required to achieve the necessary accuracy and repeatability.
The design that the
engineering team picked uses a standard thermal ribbon printer mounted on a
screw-driven Hoerbiger-Origa actuator with a servo motor and controller, so that
it can traverse across the web.
