Quality Control via Camera Inspection for Packed and Unpacked
Products
Sweets are luxury foodstuff and therefore high quality has to be
especially maintained. This is confirmed by increasing quality
regulations which are defined e.g. in the International Food Standard,
in EU laws and in national food laws or by demanding product
liabilities of companies. This affects the used raw materials as well as
the unpacked products and the packaging, including the labels.

The HELMS-INSPEKTOR

When confronted with increasing rates of production and often changing products image processing
systems can make a significant contribution for being able to follow these increasing quality
requirements. Even if camera inspection for the quality control of packaging is well established and has
improved over the years, the efforts for reducing the rate of errors in the production process are a
constant challenge for the development of more effective equipment and processes. An example for
such a machine is the HELMS-INSPEKTOR (*).

The HELMS-INSPEKTOR controls products, which are transported
on a conveyor belt with high speed in respect of various error
types. Typical errors in packaging are e.g. displaced print, welding
errors, cracks and impurities or open and empty packaging. When
dealing with unpacked products the detection of deviations in form,
colour and size as well as the identification of foreign bodies and
fragments plays a big role.
Inspection of Products on a Conveyor Belt.

An example for an application is the implementation of the HELMS-INSPEKTOR at a noted
manufacturer of flow pack packed chocolate bars (**). These emerge out of the packaging machine with
a cadence of 800 units per minute. Especially when the machine starts and stops errors in packaging are
caused, which accumulate to ca. 1 per mil of the total amount. The HELMS-INSPEKTOR assures that
the inferior parts are identified and ejected.
