Software optimises pick and place design

A Visual Components product story
Edited by the Engineeringtalk editorial team Jul 16, 2008

Visual Components' industrial simulation software is being used to optimise configurations, ensuring that, once built, systems work right the first time.

Visual Components' industrial simulation software is playing a key role in the design and manufacture of the end-of-line, automated pick and place robotic systems for packaging operations made by RTS Flexible Systems.

The simulation software is being used to help optimise configurations before proposals are shown to potential customers and ensure that, once built, systems work right the first time.

Designed to increase capacity, enhance throughput and product yield, the innovative packaging machines feature an intelligent vision system developed by RTS Flexible Systems.

The technology identifies products entering the packaging machine and is programmed to "see" a variety of items that are either substandard, or of a particular type for sorting and packaging.

Appropriate positioning and feed rate data is sent by the vision system to multiple, downstream, four-axis fast picking robots that select and pick products from the conveyor belt for processing.

To ensure a design works to a customer's requirements, RTS Flexible Systems could either construct a machine and test various options to establish the best configuration, or build a virtual model at a fraction of the price, using simulation software.

It chose the latter approach, but the problem was finding the right software.

The company already used several simulation systems.

These products all lacked the integration of statistics-based discrete event simulation and kinematic robot simulation.

Visual Components offered this al combination at an affordable price with an open architecture included an application program interface (API).

This enabled RTS Flexible Systems, with support from SimX, to directly link the programming in the manufacturer's machine vision system to the industrial simulation software.

"Using the combination of our technology and Visual Components we can optimise a system's configuration and performance, including how many robots are actually required", says Dr David Hopper, Technical Director of RTS Flexible Systems.

"Now we can be sure at the initial design and proposal stage, whereas the alternative might be to discover - and to our cost - that another robot is needed, or one is redundant, only after the machine has been built and is in use".

"This has major benefits to us and our customers in minimising risk, saving money and enhancing our competitive edge".

Besides preparing realistic and reliable sales proposals, the combined technology is also used to test 'what if' operations.

"You can design for extremes, but in the real world it's the unexpected events that catch you out", says Hopper.

"The highly realistic simulation achieved with Visual Components is also a good sales tool and facilitates requirements discussions with customers".

"What's more, we can also use the data for downstream manufacturing functions, so it's giving us tremendous value for money".
