High-speed checkweighing

For its oldest brands in the confectionery segment, the food manufacturer was looking for a reliable checkweigher combined with metal detection in the packaging line. The project was challenging from the outset. The benchmark process speed of 430 pieces per minute and the fact that the product was to be used in the food sector called for a weighing solution with MID approval for high speeds. The weighing solution also needed to have the option of flexible customisation for subsequent transitions between products. And finally, the product’s special packaging design posed an extra challenge. The sweets are packed loose in long, narrow cardboard packages, which have an extremely small supporting surface due to their design and are therefore not very stable.

Minebea Intec tendered a proposal with the checkweigher Flexus and won the contract. The checkweigher was equipped with a customised feeder as an ETO (Engineering to Order) project, which helps to ensure that the packs of products always pass through the weighing area in the correct orientation, even at very high speeds. The complex feeding and discharging technology effortlessly keeps up with the required pace. Reliable ejection of incomplete or contaminated packs of products is ensured by two high-speed separators, which push the cardboard boxes (which are oriented perpendicularly) out of the product flow. Separate, lockable run-off containers ensure that the ejected goods are stored securely.
