Latest KraussMaffei robots enable higher flexibility and energy savings
Source:Adsale Plastics Network    Editor:JK    Date:13.Dec.2021

KraussMaffei has developed the new generation of LRX linear robots. Three key benefits for plastics processors are the wide selection of axis lengths and wrist axes, optimal integration of peripherals and flexibility in complex, challenging injection molding processes.


The new linear robot product line also includes customized gripper solutions tailored optimally to the mold and the component. All components are integrated centrally into the MC6 control system and are easy and intuitive to operate.

Also, KraussMaffei is now offering the EcoMode function as a standard feature for all linear robots in the LRX series. Eco-Mode ensures that the operating speed of the robot is adapted to the cycle of the injection molding machine. This reduces waiting times but has no influence on the cycle time. This, in turn, relieves the load on the mechanical system and the drive train and provides energy savings of up to 20%.


More potential for conserving resources is offered by the optional air-saving valves for generating a vacuum with integrated air-saving control. This interrupts vacuum generation as soon as the component is gripped securely and the configured vacuum value is reached. When the threshold value is undershot, vacuum generation is activated again. Compared to conventional vacuum valves, this function uses far less compressed air.

The development of the new handheld pendant was focused on providing the operator with more information and greater convenience during operation. The new capacitive multitouch panel has a diagonal screen size of 10.1". With the high resolution of 800 x 1280 pixels and the pressure-sensitive touchscreen, the operator now has a clearly arranged view of information.


The number of configurable circuits offered in standard models has been increased from the current 4/4 to 8/8. All the latest-generation LRX linear robots now offer the ability to implement up to 8 vacuum and 8 pneumatic circuits. In addition, the media portal on the Y-axis has been optimized to make gripper changes even faster and easier.


The wide selection of pneumatic and servo wrist axes ensures high robot precision in parts handling.

The features of the linear robots in the LRX/LRX-S series from KraussMaffei include particularly fast acceleration, which enables short cycle times and high productivity. This applies to the new generation as well.


Furthermore, the LRX linear robots have precision for component insertion. "The repeatability is less than 0.1 mm. Our in-house measurements have obtained yielded values of 1.8 mm from other manufacturers. We are thus offering our customers significant added value," stated Dr. Volker Nilles, Executive Vice President New Machines at KraussMaffei.


These values shorten the mold opening time for component insertion and demolding and enable faster production in a safe process. This results in shorter cycle times and thus greater productivity in injection molding production.
