Shown for the first time: Room portal for collaborative robots

RK Rose+Krieger at Motek 2019

RK Rose+Krieger has been a partner of the Fraunhofer Institute for Mechatronic Systems Design for may years. Minden's supplier of components and systems for automation technology will be presenting the latest joint project – a triple-axis room portal for a system for robot-based processing – to the specialist audience at Motek 2019. A lifting column linkage for cobots and the upgraded MultiControl II duo lifting column controller for activation of up to four drives or two drive groups are also being shown for the first time in Stuttgart. Height-adjustable versions of the double and telescoping monitor support arms, the completely revised RK Easywork workstation system and the EPX-II KG twin-tube linear unit will also be on show.

Three additional movement axes

Small collaborative six-axis robots (cobots) always play an important role in fully automatic production environments. Compared to the larger counterparts, the light-weights do have one disadvantage: their small range of action of a few 100 millimetres. Therefore, a common solution is to use linear actuators with which the cobots can be moved horizontally or vertically to the respective location of use. The RK Rose+Krieger range in this field includes a lifting column linkage for height adjustment of cobots. This solution is of interest for height-adjustable workstations with which the collaborative robots can be positioned synchronously, for example.

The Minden company went a step further in a joint project with the research department for Scientific Automation of the Fraunhofer Institute for Mechatronic Systems Design: In order to not only provide the cobots with a linear but rather a three-dimensional upgrade, RK Rose+Krieger engineered and implemented a triple-axis room portal for a robot-aided handling system. The room axes are not superimposed over the robot axes, but they move the cobot in the room to the respective location of use. As a result there is no longer any need for costly and time-consuming conversion and resetting work. There are additional positive side effects thanks to the rigidity of the room portal, which guarantees a high level of achievable precision when using tools, and the much lower costs compared to conventional industrial robots.

Visitors to Motek 2019 will be able to see the multi-axis portal, which is made up of BLOCAN® aluminium profiles and linear actuators from the RK Duoline and RK MonoLine series, in action for the first time.

MultiControl II duo plus: upgraded lifting column controller for even more flexibility

Following the premium version of the tried-and-tested MultiControl II duo lifting column controller which was shown for the first time at the Hanover Messe 2019, RK Rose+Krieger is now introducing the MultiControl II duo plus. A basic version and premium version of this upgraded variant will also be available for delivery. The basic version of the controller can now position up to four identical drives synchronously, for example an existing table frame comprising four Multilift II lifting columns. The premium version even provides the option of defining two different drive groups and moving them either synchronously or individually. A typical application would be a control room in which the height of the table and monitors is adjusted by just one controller.

Further new functions of the MultiControl II duo plus include the service drive and the screen lock for the operating control. The service drive function helps to eliminate distortions on the system by positioning just a single drive. The screen lock protects the drives from unauthorised access.

When upgrading the controller, RK Rose+Krieger also modified the Multilift and Slimlift lifting columns and the LZ 60 electric cylinder so that they would be compatible with the new MultiControl II duo and MultiControl II duo plus controllers. Together with the complete series of Multilift II and Powerlift M lifting columns, a total of ten drive elements can now be controlled.

Visit RK Rose+Krieger at Motek in Stuttgart in Germany from 7 to 10 October 2019, hall 4 / stand 4411.
