This highly dynamic planar surface gantry EXCH is beating all speed records. It is 30 percent faster than any conventional Cartesian handling system while the initial costs are comparable. Festo developed this high-speed handling system for dynamic assembly operations in which small and light mass-produced articles need to be positioned quickly and flexibly. It can now be ordered very easily in a package – with just one part number for the handling system, including a control system CMCA.
The planar surface gantry EXCH covers the working space of 2 SCARA robots. It has a rectangular working area that is significantly larger than that of robot systems with delta kinematics. These can work only in areas which are round or kidney-shaped and have other disadvantages such as high costs, a mass of around 150 kilograms to be fitted and a need for a large installation space.
Flat, quick, precise
EXCH is very flat and has a low centre of gravity and a simpler frame than high-speed delta robots. Its optimised acceleration and braking characteristics enable an accuracy of 0.1 mm during suction pick-up and gripping.
The H-gantry has a speed of 5 m/s and achieves acceleration rates of 50 m/s² thanks to a clever design that connects both EGC toothed belt axes to the cross member with a single rotating toothed belt around the drive shaft. The belt is driven by two servo motors EMMS. An added benefit is that there is no need to move a motor in the X/Y plane, which has two degrees of freedom. Reduced mass facilitates fast, dynamic motion and results in less wear.
With the CMCA, users receive a complete, ready-to-install control package for the planar surface gantry EXCH – with an axis controller, 3D motion control, motor controller and safety concept. This provides machine and plant constructors with an uncomplicated solution for complex and highly dynamic handling tasks which can be ordered using only one part number.
Each complete system is delivered by Festo with the basic parameterisation so that commissioning is quick and easy. The integrated safety concept is especially helpful as it can be easily integrated into a customer's safety hierarchy. What is more, attractively priced standard solutions are available, offering basic projects pre-programmed in CODESYS.
Supplied ready to install
Fully assembled and tested, the ready-to-install system solutions are delivered right to the machine – together with all the design data and circuit diagrams, and of course with a comprehensive functional and fixed-price warranty. Users receive not only hardware in the form of a ready-to-install subsystem but a complete value-creation package. Complete solutions of this kind ease the burden on technical personnel, keep design costs low, simplify the procurement process and reduce process costs.
