In addition, the systems rely on chains, roller bearings, timing belts and other mechanics that become more complex – and difficult to maintain – as system size expands.
Making the Move to Independent Cart Technology (ICT)
Independent cart technology (ICT) – based on linear synchronous motors – changes the paradigm for disposable medical device manufacturing.
How? Linear motor technology allows conveyor modules to be configured end-to-end, creating an electro-magnetic force to propel carriers transporting product much faster than traditional systems.
And because independent cart technology uses far fewer moving parts than conventional fixed systems, machine complexity and maintenance is kept to a minimum. Fewer mechanical parts also means less component-generated dust, debris and oil residue – an important consideration for clean room environments.
When it comes to maximizing flexibility – and doing more in less space – modular independent cart technology is a game-changer. Each carrier moves independently and is fully configurable and programmable to easily accommodate process, assembly and size variations.
Due to independent motion, the speed at which carriers move to each process station is based on the time it takes to complete that process – not a fixed conveyor rate. In addition, carriers can return to a previous station if the same operation is required more than once in the product run. Or carriers can take a parallel path – imagine a highway exit ramp – to accommodate different process steps with minimal impact to machine footprint.
And because independent cart technology is based on establishing and maintaining carrier position at all times, it intrinsically creates a high-fidelity track and trace record. For medical device manufacturers, this functionality can streamline validation and compliance.
For machine builders who have incorporated independent cart technology, the results have been impressive. Many report reducing machine footprints and/or increasing throughput by 50 percent or more.
