New sizes for roller bearing system
Guideline, Hoerbiger-Origa's highly successful aluminium profile roller bearing system, has been expanded to include new sizes and options to address an even wider scope of applications.
"We had installed a fully automated shrink-wrapping line into a customer's plant in February of 2006 which incorporated a double guided rodless pneumatic cylinder, controlled by a 5/3 open-centre solenoid-operated spool valve" John Ellison, a Project Manager with Adpak, said.
Initially, this worked well, but we found that if the machine was idle for any length of time (for example, during product type changeovers) the cylinder would "creep" and lose its default start position.
The use of a 5/3 spool valve also made it difficult to control the action of the cylinder after an emergency stop.
Once air pressure was re-applied to the cylinder, it would move violently in one direction or the other, scattering product in its path.
Eventually, due to the rigours of a three-shift working system, the cylinder gave up the ghost (a maladjusted seal-strip and wear proved to be the weakest link).
Adpak decided that a more robust, reliable and controllable rodless pneumatic cylinder solution was required for the job, a 40mm bore Hoerbiger Origa OSP-P rodless cylinder, fitted with Slideline guide and integrated VOE 3/2 poppet valves fitted the requirements perfectly.
"Having used a similar (although much smaller 25mm bore) unit on an earlier project, we were impressed with the build quality, value and controllability of the cylinder", explains Ellison.
"The integrated 3/2 valves allow us to leave the cylinder standing without it creeping".
"We can also allow the cylinder to be pressurised and de-pressurised without risk of any sudden violent movement".
The integration of control valves directly in the cylinder end caps ensures the fastest possible response, faster cycle times and reduced air consumption - all of which benefit machine productivity.
The customer also said that the operation of the whole system now seems far smoother.
This is a direct result of the low friction, low wear and maintenance free sealing system of the Origa cylinder, which similarly contributes to greatly extended service life. Request a free brochure from Hoerbiger-Origa ...
