| Specification: | Dimensional Testing of Cans for the Food Industry
Accurate dimensions and shape of the
prefabricated cans and can-lids is of prime importance, in order to ensure that the lids and the cans match properly and form a permanent airtight
seal after the filling and sterilization process. This in order to avoid costly batch sealing failures in the canning industry. A special non-contact automated measurement testing machine was developed to
control the dimensional integrity of the cans and the matching lids. The machine determines with the
aid of a laser-optical sensor. The exact location and dimensions of the corrugations, the unfolded seam
stitching height and the nominal core-height of the lid. The MICRO-EPSILON optoNCDT used in this machine is not influenced by variations in basic
container material colour, or by preprinted advertising illustrations and text in a wide variety of
colours on the cans or the can-lids. Accurate measurement test results are therefore guarenteed.
Reasons for cho- High repeatability of and consistency of
measurement values especially by various
reflecting materials, aluminium, surface treated
sheet-metal etc., as well as insensitive to rapid
colour variations of preprinted advertising
illustrations and texts.
- Extreme small laser-beam measuring point
especially well suited for measuring exact
dimensions of small corrugations.
- Possibility to transfer data directly into a computer
for visualization and statistical data storageosing the system |
