KHS has launched a new low-noise preform processing system, with optimised tipping and easy operation as added benefits.
Offering less noise and improved quality, the new preform processing system from KHS Corpoplast – InnoPET Silent TipTainer – sees PET preforms fed to the sorting unit especially gently, resulting in a considerable reduction in the amount of noise around the tilter.
“With the Silent TipTainer we’re achieving a much lower preform rejection rate than has been the case to date,” explains Alexander Heller, technical project manager and developer for preform conveying systems at KHS Corpoplast.
The reason for this is that the drop height of the PET preforms into the tipper has been greatly reduced. Where the rejection rate was previously at 3%, just 0.25 to 0.3% of all preforms are now damaged during tilting or by bumping into one another as they fall.
The lower drop height and smooth tipping in stages not only mean that preforms are handled more gently and that there are fewer breakages on the necks; the adapted tipping process also results in perceptibly lower noise levels.
KHS measurements record a maximum of 80 dB(A). The closed system also ensures that values of up to 110 dB(A) are no longer standard.
By reducing the amount of noise pollution occupational safety is improved further for operators working near the tipper.
According to KHS, best product quality is obtained by filling the optimised box tilter silo unit by up to two preform loads.
At a higher preform density damage can be caused by the preforms falling onto one another.
In the compact and hygienic Silent TipTainer the risk of contamination by dust or other foreign matter is reduced to a minimum.
