Espera ESVS Vision System

Espera has developed a cost-effective vision control system that automatically verifies packages using high-resolution inline cameras. The ESVS Vision System can be used as a standalone quality control system, or integrated inline with any existing Espera weigh price labellers.

The vision system provides full quality control of packed and labelled products at speeds of up to 150 packs/min. An integrated conveyor system allows for precise examination of the packs and labels from either the top or bottom, or both, with automatic height adjustment to suit packages of varying heights.

The ESVS system can check finished packs to ensure that the products have been packaged and labelled correctly and in accordance with the predefined records and criteria stored in the database including pack dimensions and outlines; label position and alignment; label contents such as text, weight and price fields; barcode readability and content; logos; seal area; and presence of foreign bodies.

Statistical reports can be generated for many criteria including checked packs, correct packs, rejected packs, line speeds. Versions are available with top only, bottom only, or top and bottom camera configurations.

By automating the time-consuming manual aspects of QA checks, the system enables users to better direct their QA resources and helps to prevent product recalls.
