The assembly controls the size change of nine different points within the machine.
Needing to be highly accurate, fast, robust and safe RML designed and manufactured a number of assemblies that were fitted to an existing AZON thermal break saw and chemical applicator.
Using a recipe system stored within the controller the operator is able to easily select the product to be run, instigate the change and the servo motor control will position the mechanisms for that product.
Nalco operates an existing thermal break machine to feed widow and door extrusions into the resin application process. When changing from one extrusion size to the next, the changeover process was manual and required very precise positioning. The resulting product wastage and lost time were due to the required fine tuning between every changeover.
RML developed a solution whereby the manual vertical and horizontal adjustment controls were replaced by nine servo controlled actuators. The accuracy of the servo positioning allowed very precise and repeatable setup of the line, thereby eliminating the requirement to fine tune the adjustment and resulting lost time and product wastage.
The improvement in changeover speed and accuracy has allowed Nalco to process in less than a single shift, what used to take up to two shifts.
In addition, the wastage from the process has fallen by 97%
The two packers that are used for the dessert products have the added complexity of an integrated elevator to lift the packs from the forming level to a height which suits the palletiser infeed and provides clearance for a pedestrian walkway.
These machines are running at their maximum output speeds and have performed exceptionally well, requiring only routine maintenance in the form of a weekly service. The elevator system is very reliable and requires little maintenance to keep it performing as it should.
Of all of the types of packers that we have on site (past and present) the RML packers have proven to be one of the most reliable, and easiest to maintain.
Their open and honest approach and their willingness to work close with the MilkTestNZ team has resulted in very positive outcomes for us.
The design process went very smoothly with regular reviews and we were fully engaged throughout by RML’s engineering and design team.
Our start up and commissioning went somewhat better than we had anticipated and we have been pleased with RML’s performance and the performance of our new packing line.
In general, we have found the RML team to be professional, proactive and very responsive to questions and quick to resolve any problems for us.
The RML team took the time to understand the requirements for the overall plant and supported areas outside their scope to ensure the overall project was a success.
We look forward to working with the RML team again in the future.
