Accurate placement for tub lid insert

Unilever Best Foods (Nederland) recently had the task of sourcing a machine that could handle a special pack design for its Becel (Flora) pro.activ spread.

The requirement was to combine the cartoning with an automatic product feeding system, plus the insertion of an information booklet, with a speed requirement in excess of 220 packs/min.

Kliklok Woodman won the contract and built three complete packaging systems comprising Servo IPTU (Intelligent Product Transfer Units) feeding the margarine tubs broadside into a conveyor system that accurately positions the product to allow placement of the booklet into the indented lid of the plastic container.

The booklet feeder, which is servo driven and integrated into the infeed conveyor of the Prima end load cartoner, was a key element of the line’s design.

Unilever’s project manager Marc Olthoff says “Kliklok Woodman offered a feed geometry which allows accurate positioning of the leaflet into the tub lid, and this was a key factor in our decision to place the order with them.”
