Sensors Enable Stable Detection of Color Marks on Food Packages

KYOTO, Japan -- OMRON Corporation introduces the "Color Mark Photoelectric Sensor E3S-DC Series (E3S-DC)" and "Color Fiber Amplifier Unit E3NX-CA Series (E3NX-CA)" targeting food and beverage makers faced with an increasing difficulty to detect color marks printed on diversified product packages.

Used in combination, the E3S-DC and E3NX-CA can stably detect color marks which are printed on glossy or colorful materials with subtle differences in colors and previously difficult to detect, cutting back on time necessary to start production and do maintenance work, contributing to an overall productivity increase in the packaging process.

Faced with increasingly diversified consumer needs, the food and beverage industries are developing new products almost on a daily basis, diversifying packaging materials and designs in the process. Given such circumstances, manufacturers have been looking for a sensor capable of detecting, stably and simply, color marks printed on all sorts of materials in order to keep their plant running stably.

In response, OMRON cooperated with its customers to develop the E3S-DC and E3NX-CA which incorporate OMRON's proprietary sensing technology and algorithm to stably detect "differences in colors" under various conditions. The combination of the E3S-DC and E3NX-CA not only reliably detect color marks on a variety of packaging materials but also optimize initially set parameters to adjust to changes in manufacturing lots, contributing to a stable operation of the production plant.

Reliably detecting color marks on various packaging materials - The "Super High Dynamic Range" function requires only a simple setting to stably detect color differences between marks and the background printed on glossy materials including aluminum vapor deposition film. - The "Low Noise, High S/N Ratio Light Receiving System" reliably detects subtle differences in similar types of color often used on colorful packaging with little color differences.

Optimizing settings to adjust to lot changes - Color information detected by a sensor will be transmitted to upper layer equipment such as a programmable logic controller via EtherCAT (R). Color variations resulting from various lots can be easily managed in a database and sensors can be adjusted for optimal settings to keep the plant from an abrupt shutdown and maintain a high operational ratio.
