Application

Detecting the presence of transparent containers

The Challenge

A leading manufacturer of containers for the consumer goods industry needed to detect the presence of transparent containers for labeling, position detection and production counting purposes. It was imperative that the object detection be precise, repeatable and able to detect transparent, frosted and opaque objects.

High-cost, specialty sensors are often used to detect transparent objects. A compact, cost-effective, yet high-performance and easy to use solution was needed.

Application

Verification of tamper evident seal

The Challenge

A major manufacturer of shrink sleeve labeling and tamper-evident shrink banding systems needed to verify the presence of tamper-evident seal placement. Verification needed to be performed on every container during the high-speed process. Tamper-evident seals are mandatory for pharmaceutical products making it vital to verify the presence of the seal in the packaging process.

Use of shrink band films with optical brighteners to provide a tamper-evident seal has become a cost effective solution to improving the level of security provided by manufacturers in their products.

Application

In-line blow molding opacity verification

The Challenge

One of the important factors in bottle use is the light barrier that the bottle provides to its contents. Since HDPE is a naturally translucent material, pigments are added to create the necessary opacity for the container. The most popular pigment is titanium dioxide, which provides excellent opacity and white coloring. During the manufacturing process it is important to maintain the required quantity of the pigments to achieve the proper opacity acceptable to the customer while protecting the contents from the damaging affects of light.

Application

Verification of glue placement for folder/gluer

The Challenge

A leading supplier of glue application and glue detection systems needed to verify the placement of glue on various packaging materials in a high-speed process to improve quality, throughput and to reduce operating cost by minimizing down-time. Proper glue placement on seams is necessary for packaging integrity.

The Solution

EMX Industries, Inc. has developed the UVX-300G-C Luminescence sensor designed to detect the presence of a wide variety of adhesives with luminescent tracers.

Application

High-speed clear label presence verification

The Challenge

A major manufacturer of labeling systems for cosmetic, food, chemical and pharmaceutical industries needed to verify the placement of clear labels in the high-speed labeling process to guarantee presence of product label on a wide variety of containers and cartons.

Currently, clear labels are difficult to verify due to the transparent properties of the label. Vision systems are often unable to reliably detect the presence of clear labels.
