HEUFT systems are responsible for labelling and inspecting the quality of filled yoghurt jars at Emmi.
Applying tamper evident labels precisely to the lid, fitting jars accurately with back and body labels, examining the end product carefully for foreign objects and rejecting faulty packaging consistently: HEUFT has integrated two systems along a jar filling line for premium yoghurts at Emmi Frischprodukte AG in Ostermundigen, Switzerland, in order to perform these tasks.
An extremely compact labelling machine with only one carousel was required in view of the lack of space on site. Nevertheless it should be able to place three different labels exactly there where they belong. The solution: the HEUFT TORNADO D. It sends the jars through twice. During the first circuit they are subjected to a camera–based and servo–controlled alignment using the opening tab on the closure and then fixed into specially constructed clamping starwheels.
During the second throughput the lids are fitted with adhesive labels first. Their tamper evident strips are pressed exactly onto the body of the container. Finally the wet glue labels are applied to the front and back of the jars. The triple labelling is so precise that the strips of the closure labels are always centrally positioned under the body labels. The presence and position of the labels are checked optically before the containers leave the machine.
Then it is off to the foreign object detection in the HEUFT eXaminer XA the unique X–ray and image processing technologies of which provide maximum detection reliability.
