T4000 package inspection system

High Speed Inspection System for Plastic, Metal, and Glass Containers



Versatile Inspection/Advanced Control

The TapTone 4000 is a versatile package inspection system capable of examining containers for leaks, fill level, physical defects, pressure and vacuum. The system's software gives users greater control over their product set-up and changeover, rejector set-up and alarms, "last reject" values, and autotracking. The system combines the latest technology, an intuitive user interface, and a long-standing record of high reliability, making the TapTone 4000 a cost effective solution for inspection of your plastic, metal, and glass containers.

Acoustic Technology

Measures pressure or vacuum in containers that do not have a measurable lid deflection—such as beer bottles, coffee bricks, plastic jars with composite closures and milk-based drinks in steel cans. The acoustic sensor works by applying a "tap" to the top of each container. The tone response is directly proportional to the pressure or vacuum inside the container. The frequency of the tone is measured and compared to user set reject limits where containers outside the limits will be rejected. The acoustic sensor is used on metal lids or crowns where the product does not touch the lid.

Proximity Technology

Measures pressure or vacuum in food cans, beverage cans, glass jars, and bottles with pop-button lids by measuring the lid deflection. The proximity sensor produces a continuous magnetic field that monitors the distance to the metal lid and produces a proportional analog voltage. The continuous proximity signal is digitally sampled to produce a merit value of the lid profile. The profile value is then compared to user-set limits. Containers with lid deflection outside these limits are rejected.

X-ray Technology

Measures the product fill level in steel, aluminum, glass, plastic and paper containers. An X-ray tube is used to produce a low-energy X-ray beam. The X-ray beam penetrates the side of the container in the area of the fill level. An X-ray detector is positioned on the opposite side of the container to measure the intensity of the beam after it goes through the container. The intensity of the beam is then compared to acceptable energy levels to determine the relative fill level of each container. The X-ray sensor is used to measure both overfilled and under filled products in all types of containers.
