DCOS Sweden AB is proud to announce a substantial contract to retrofit the existing Bosch Rexroth drive system at OTM Avistryk Herning-Ikast A/S in Ikast, Denmark. The existing equipment consists of two Goss Universal 45 presses, with a total of twelve 4-high printing towers and two folders installed in early 2000, comprise over 70 drives and motors. The presses are by an EAE press control system and AMAL splicers.
In the 1990’s, Bosch Rexroth, with its well-known brand Indramat, took part in transforming the graphic arts industry from traditional mechanical line shafts to shaftless drive transmission. In the last 20+ years, Shaftless technology has been the predominant method to run and control printing presses and industry leading OEMs like KBA, Goss, DGM, and Solna has relied on Bosch Rexroth´s technology.
Many of these presses were equipped with the DIAX series of drives and the CLC motion controller. All based on SERCOS II fiber optics. Like all electronics, the service life of components is limited and especially on power electronics making the DIAX system a challenge to maintain today. There are many short-term solutions available to extend service life for a few years, but most do not involve any change in technology. This approach only delays the inevitable, which is a complete retrofit in the near future.
In 2015 DCOS developed an industry unique Retrofit concept for the DIAX platform, a step-by-step migration of the old DIAX system to a modern drive system platform, the same platform we use on new presses toady. The investment is targeted towards a new state-of-the-art technology, and gradually the old SERCOS II fiber optic system is removed and replaced with a standardized, non-proprietary Ethernet based bus system.
OTM Avistryk realized a few years back that they needed to extend the operational life of the Bosch Rexroth system on their Goss presses to fight obsolescence and to ensure uptime of their presses.
