Sanofi-Aventis ensures product quality with METTLER TOLEDO Checkweighers

Sept. 7, 2010 - PRLog -- Standard checkweigher components add to process reliability
A good product countercheck (“good philosophy”) is performed by a downstream light barrier to ensure that all bad products have been successfully sorted.
At this point, the downstream drop-down conveyor is lowered to guarantee that only good products are sent down the line for further packing.

In this fashion all products located on the checkweigher are removed from the transport path and any incomplete drug packages are safely removed from the production process. The checkweigher then triggers the conveyor belt to stop by means of a time delay, thus enabling operating staff to perform an additional quality-control check.

The checkweigher is operated via the user-friendly touch screen terminal, with individual user profiles programmed for separate operators.

Gliding limits are based on the nominal weight of the pharmaceutical products
As the weight of all the individual package components can vary from batch to batch, the “gliding limits” function is used to take these weight fluctuations into account by defining variable upper and lower limits. This enables medium- and long-term fluctuations against the mean value to be recorded and remedied which in turn enables compensating for long-term fluctuations by using these newly calculated tolerance limits. The removal of the defective products under the “gliding limits” option is based solely on the nominal weight of the pharmaceutical product.
