Dual Carriage Extrusion Blow Moulder Upgrade

Fastest possible turnaround with B&R control system

KlareTech recently completed a control system upgrade on an old dual carriage extrusion blow moulding machine.

It is common place in many factories to find machines that have been shelved due to ageing control systems. In many cases these machines are mechanically still in near perfect condition and they end up being put aside only because of the cost of replacing failing electronic control components that are becoming obsolete. KlareTech provides an opportunity to breathe new life into these machines.

A perfect solution in the case of extrusion blow moulding machines is the B&R blow moulding upgrade solution. Fully developed touch screen HMI with process animation provides an intuitive operator interface. Software from B&R which is already 80% complete means a less 'buggy' experience than many other upgrade solutions on the market which often require software to be written from scratch. The turnaround time for the installation is also unusually fast among the competitors in this segment.

Blow moulding machine upgrade using B&R

Seamless Integration of complex extras

In our latest onsite upgrade KlareTech went all the way.

This dual carriage extrusion blow moulder had every possible additional feature - Takeout robots, In-mould labelling robots, hydraulic scrap remover and needle-blow.

All of these features were seamlessly integrated into the B&R blow moulding control platform running on a Power Panel 400 embedded HMI/PLC with X20 IO.

An 8-layer parallel control sequence means that every movement is adjustable to ensure flexibility for handling the most complex tasks.

The below video shows one of the most complicated bottles currently blown in the South African market running smoothly with a cycle time of 14 seconds all controlled with our upgraded system.

Each movement in the process chain has a delay adjustable with a resolution of 10ms and if you think that 10ms doesn't make any difference you obviously haven't

worked with needle-blow before. 

Hydraulic mould movements on the machine involve proportional control of flow valves based on analog feedback from position transducers. The hydraulic blowpin movements are simple proxy to proxy movements with simple directional hydraulic valves and robot movements are all pneumatically controlled.
