Checkweighing

Checkweighing or checkweigher is a manual or automatic machine for checking weight of packaged and unpack-aged goods. Predominantly used within the food industry. Checkweighing consists of a system that incorporates belts and weighing terminals for high speed production lines. Also known as in motion scales.

Checkweighing – Alternative Names

Also known in different locations around the world by many different names to include, dynamic checkweighers, in motion scales, belt weighers, check scales, high speed precision scales, conveyor scales or dynamic scales.

Checkweighing – Typical Set Up

Checkweigher systems have a set of belts, we use quick release belts that require minimal production down time.  As the packages pass over the load cell the system will record the package weight. If the package is within the set tolerances. The package will pass through to the next stage which would normally involve an inspection system.

Alternatively packages will be rejected if they are outside the set tolerance for the items being weighed. Any over weight or under weight packages will be rejected with pushers or we can incorporate a pneumatic option to reject the goods.

Checkweighing with Inspection

Furthermore due to the very high industry standards within the food sector. More often a requirement is to have at least one inspection system. One of the most popular solutions for production the integrated x-ray food systems. Not only checking for metallic objects but can detect, rubber, plastics, bone and even the product density.

Also metal detectors are still very popular, checking for ferrous and non ferrous metals. Each inspection system will again reject any goods that fail the checks whilst passing along the belt lines.

In addition to the internal inspection there is now a growing need for vision inspection. Checking the package integrity from above and below. Checking seam and seal and ensuring that every package is perfect before it leaves the line. A photographic archive created for each and every item leaving the line.

Also the vision inspection systems check the correct packaging is used. The correct labels with the correct print layout. Bar codes,  sell by dates recorded and monitored. Any package that fails again rejected with pushers.

Checkweighing machines easily adapted for any time of production environment. Each system easily tailored to the customers particular requirements.
