HEPCOMOTION LAUNCHES THE NEW high performance Driven Track System DTS2


This month, HepcoMotion brings a brand new product to the worldwide market. The DTS2 Scroll Driven Track System has been developed to cater for high speed applications with significantly larger driving forces.


A FLEXIBLE DRIVE SYSTEM – SIMPLE, YET CLEVER!


O


ne business that already knows the benefits of this new track system is


Robotronic AG, the Swiss sole agency for Mitsubishi robots. The company focuses on individual automation solutions for the self-developed robot cell MRT (Modular Robot Technology) – a feeding system for the pharmaceutical packaging industry. The combination of Robotronic’s


modular design and HepcoMotion’s linear systems offers an individual solution, ready for serial production. Mike Weber, general manager of


Robotronic AG, and his team in Winterthur invested three years of hard work into developing the MRT robot cell. His philosophy: Finding easy and cost- efficient solutions for complex tasks. Early in the development phase


Mike Weber was looking for a very flexible drive system. One of his business partners made him aware of HepcoMotion, a supplier of linear motion systems from Tiverton who also builds customised special components. The family-run company has developed and distributed linear motion solutions for more than 45 years. Weber analysed the products which can not only be used separately as individual units but also combined with different technologies to build linear, rotary and continuous systems. From the beginning he was impressed by the cleverness of the systems which can be customised individually for most diverse requirements. Weber prefers continuing business with


the same supplier so that he knows the systems through and through. That is why it is so important for Weber to collaborate with companies such as HepcoMotion – to further standardise their modular system and reduce the risk of failures and quality problems. Now that the MRT system is ready for


serial production, the proof of concept is taking place at a well known international customer in the pharmaceutical industry. Small glass vials in packs of five are moved onto a transport system by the new robot cell, where they are packed into blisters every second and afterwards put into a cartoning machine. This is carried out by two parallel


working robots, each of which equipped with a double gripper to pick up two times five vials and put them into blisters. The trays containing the ten vials are transported by an accurate screw drive; the carriages are directed and driven by a belt between V-slides. A Mitsubishi servo motor controls the position of the blisters. Mike Weber explains that he was looking for a system that works very precisely. On the one hand the vials are made of fragile glass and can break easily; on the other hand the handling was supposed to be working both rapidly and precisely together with the robots and the feeding system. This is necessary to guarantee high efficiency and avoid problems such as machine breakdowns. According to Weber, HepcoMotion’s system meets these challenges. Its design works with high speed and still is mechanically robust and very accurate. Stefan Kaufmann, HepcoMotion’s salesman for Switzerland, explains the new DTS2 system which was used here: “The Dynamic Track System ‘DTS2’ uses a screw drive that positions the carriage exactly where it is needed. In this special application, six carriages

are placed with a positional accuracy of ±0.2mm. An extra long drive screw was built for this custom-made design so six carriages can be driven by


one screw. The carriages themselves (21 all in all) are fixed onto slides. On the outside these carriages are connected with a belt, just like a railway.” In Weber’s opinion, another reason why the modular design and the DTS2 system match so perfectly is the possibility to combine it with Mitsubishi motors. Standard motors are often used together with ready designed systems – with HepcoMotion’s solution, they can work with their own individual motors. When using Mitsubishi


motors, up to eight extra servo axes can be driven directly by the robot system. The additional


axis is designed for the robot and operated by the robot controller. This is an

interpolating task which must be carried out with high positional accuracy, another important aspect. This system offers a very flexible but at


the same time robust and easy to handle technology which mechanical construction guarantees high positional accuracy during a long system life. Weber plans to use HepcoMotion products as standard component for their modular systems. Using these components, they are able to be more dynamic and drive the screw with higher speed without risk for the belt to skip. Weber and his team compared HepcoMotion products with those of competitors. The company is convinced that the quality guarantees a highly functional and low-maintenance system for their own customers – and all this for decades.
