Festo's New T-Gantry and H-Gantry Herald a New Era in Packaging Handling Systems with Packing Cycle Times of 670 Milliseconds

Festo delivers the systems directly to the packaging machine, ready to install and adapted to all required machine interfaces.

HAUPPAUGE, NY, June 25, 2012 - Festo's new highspeed

H-gantries and T-gantries are 30 per cent faster than
conventional handling systems. They herald a new age in
packaging technology, combining the dynamic response of a linear
motor handling system with the costs of a toothed belt handling
solution.

These two handling systems represent real alternatives to
expensive and complex robot systems such as robots with delta
kinematics and SCARAs. Festo delivers the systems directly to the
machine, ready to install and adapted to all required machine
interfaces.

High-speed T-gantry
The high-speed T-gantry can easily achieve cycle times of 670
milliseconds. It is a high-speed pick and place unit with a higher
dynamic response than a conventional linear gantry and can be scaled
to any stroke.

The gantry has a speed of 4 m/s and achieves acceleration
rates of 50 m/s² over the entire working area thanks to a clever design
that connects both 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 the fact that the motors do
not need to be moved within the X/Y area with its two degrees of
freedom. Reduced mass and two servo drives, which are mounted
parallel to each other, facilitate fast, dynamic motion and result in less
wear.

High-speed H-gantry
The 3D/planar surface gantry distributes packaged foodstuffs
such as small chocolate bars to boxes. It covers a rectangular working
area that is significantly larger than that of robot systems with delta
kinematics, which can only work in round or kidney-shaped areas.

Other disadvantages of many delta robots are the high costs, the
installation weight of approximately 150 kg, and the large installation
footprint.

The high-speed H-gantry, on the other hand, can be scaled to
any stroke, has a very low profile, a low centre of gravity, and a
simpler frame than high-speed delta robots. Its optimized acceleration
and braking characteristics enable strokes of two meters and one
meter along the X- and Y-axes, with an accuracy of 0.2 mm.

The rotary/lifting module of the high-speed H-gantry is
ingenious too. It consists of a hollow shaft with integrated energy
through-feed for the front-end module and forms the Z-axis to which
the gripper unit is attached. The rotary/lifting module accelerates to a
speed of 1.5 m/s at a rate of 20 m/s². Vacuum and mechanical
grippers with work piece loads ranging from zero to two kilograms can
thus be operated.

Robotics for system solutions
The handling system is based on the robotic controller CMXR. It
combines mechanical systems as well as electric drive and control
technology to form a complete kinematic system solution and
coordinates highly dynamic motion in 3D space. The robotic controller
CMXR interpolates and positions all the axes that can trace contours
on a center line. Contour switching points can be set and used for
accurate activation of process equipment.

The CMXR also acts as an interface to master controllers on the
one hand and to the motor controllers of the servo axes and the valve
terminals on the other. And that's not all. The controller also supports the
integration of vision systems such as the intelligent Compact Vision
System SBO..-Q from Festo. Applications involving moving objects
can also be realized with the help of the vision system and the
available conveyor systems.

Easy subsystem integration
Festo delivers the ready-to-install system solution directly to the
machine, fully assembled and tested. All pertinent engineering data
and circuit diagrams are also supplied, together with a comprehensive
operating and fixed-price guarantee. Customers in the packaging
technology sector receive not only hardware in the form of a ready-toinstall
subsystem, but also a complete value creation package.

Complete solutions reduce the workload for technical staff, keep
engineering expenses to a minimum, simplify the procurement
process, and reduce process costs.

BitFlow Introduces 6th Generation Camera Link Frame Grabber: The Axion

BitFlow has offered a Camera Link frame grabbers for almost 15 years. This latest offering, our 6th generation combines the power of CoaXPress with the requirements of Camera Link 2.0. Enabling a single or two camera system to operate at up to 850 MB/S per camera, the Axion-CL family is the best choice for CL frame grabber. Like the Cyton-CXP frame grabber, the Axion-CL leverages features such as the new StreamSync system, a highly optimized DMA engine, and expanded I/O capabilities that provide unprecedented flexibility in routing. There are two options available; Axion 1xE & Axion 2xE. The Axion 1xE is compatible with one base, medium, full or 80-bit camera offering PoCL, Power over Camera Link, on both connectors. The Axion 2xE is compatible with two base, medium, full or 80-bit cameras offering PoCL on both connectors for both cameras. The Axion-CL is a culmination of the continuous improvements and updates BitFlow has made to Camera Link frame grabbers.
