Shorter Cycle Times, Enhanced Reliability, Less Complexity by ENGEL

ENGEL to present new multidynamic at Fakuma 2018; Shorter cycle times, enhanced reliability, less complexity

When introducing multidynamic three years ago, ENGEL set new standards for performance and efficiency in the use of linear robots. The software automatically adapts the speed of the robot movements to the current load and thus shortens the cycle time in many applications. Whereas the previous release was only able to optimise the speed of the linear axes as a function of the load, multidynamic now also controls the speed of the servomotor-driven rotary axes and therefore leverages further efficiency potentials. ENGEL is presenting the new development for the first time at Fakuma 2018 from 16 to 20 October in Friedrichshafen, Germany.

Traditionally the maximum speed and acceleration of the robot movements is designed for the maximum load-bearing capacity and the greatest possible strokes, but few applications fully exploit this spectrum. This is exactly where ENGEL comes in with multidynamic. When loads are lower and strokes shorter, ENGEL viper robots equipped with multidynamic move faster, thus enabling shorter cycle times.
The software belongs to the standard range of all ENGEL viper robots. It automatically controls the speed and acceleration as a function of the load, thus combining the shortest possible cycle times with the best possible precision, energy efficiency and service life of the mechanical components. The plant operator does not need to manually optimise the robot speed, a fact which accelerates the production process start-up.

Reduce handling times by a further 10 to 30 percent
What is new is that multidynamic calculates and automatically sets the optimum speed not only for the linear movements but also for the movements on the servomotor-driven rotary axes. The software determines the maximum allowable dynamics from the weight handled and the gravity distance from the rotary axes. Through this additional optimisation, the handling time can be reduced by a further 10 to 30 percent in rotation-intensive applications.
If the system detects an overload due to excessive handling weight or an increased distance to the centre of gravity, it outputs a warning message for the system operator and thus actively contributes to preventing excessive wear on the mechanically-driven components, or even system failure.

Premiere at Fakuma
At the Fakuma, multidynamic will be demonstrating its impressive new performance for the first time. To allow this to happen, injection moulded parts with and without additional weights will be alternately picked up and moved by an ENGEL viper 20 robot. Visitors to the fair can follow live on the injection moulding machine’s CC300 control panel how the robot identifies weights and gravity distances, slowing down both its linear and rotary movements when the gripper picks up the component with an additional weight and accelerating again when the gripper is carrying less weight. The determined masses and gravity distances as well as the corresponding cycle times are clearly displayed and documented on the CC300 control.
The multidynamic software is available for ENGEL viper robots of all sizes as a standard feature. The first viper robots with the new multidynamic will be delivered starting in April 2019.
