EyeSens Object Counter at the production of condoms

The applications for the EVT products – especially the EyeVision software – is many fold. Often seemingly complex tasks are solved with simple commands into EVTsoftware, for example the “Object Counter” in the inspection of production and packaging of condoms.

Condoms are not only a product where hygiene and quality are essential, but sometimes there are also characteristics, which require special inspection systems.

The EyeSens vision sensor with the EyeVision software has been used at the production site of the world's largest condom manufacturer since 2005. The company built a new factory in China in addition to its main plant to produce 1.15 billion condoms a year.

They now export their products to more than 80 countries through international organisations such as the World Health Organisation (WHO) and the United Nations Fund of Population Activities (UNFPA).

The current case shows a unique solution with the simple method of BLOB-analysis. BLOB (Binary Large Object) is a fundamental technique of machine vision, based on analysis of consistent image regions. It is a tool of choice for applications in which the objects being inspected are clearly discernible from the background. The diverse set of Blob Analysis methods allows the user to create tailored solutions for a wide range of visual inspection problems.

The condom application uses the EyeSens ObjectCounter – a vision sensor with specialized command set, including the BLOB command of the EyeVision software. The command has to define if the condom is packaged with the right side up. These specific condoms are applied with a treatment that delays ejaculation  requiring that treatment is applied to the correct side. The EyeSens system decides which way up the condom is, to ensure that the correct side of the condom is showing to be treated.
