CASE INSPECTION TECHNOLOGY

T4000 Case System
Case Inspection for Metal Cans or Glass Jars
with Metal Closures
The T4000 Case system is designed for non-contact, non-destructive, 100% automatic
container inspection through a sealed cardboard and/or shrink wrapped case. The
system offers the option of acoustic or proximity technology to inspect glass jars with
metal closures or metal cans for pressure or vacuum after the containers have been
sealed in the case. In many applications, the T4000 Case system will detect defects
other than low pressure or vacuum. Some examples are missing containers, containers
with missing lids or broken bottles, flat sours and damaged cans.

How It Works

Features

Applications

• 100% non-contact inspection

• Vacuum/Pressure inspection in metal cans

• Large PC touch screen

• Vacuum/Pressure inspection in glass jars
with metal closures

• Graphic screen shows defects in case
• Acoustic and Proximity sensor heads (up
to 4 heads)

• Missing cans
• Broken or missing glass bottles

• Quick set sensor bridge for easy

product changeover
• Speeds up to 250 cases per minute
• NEMA 4x, stainless steel, water wash

down (user interface enclosure and
control enclosure)

Acoustic Technology
Acoustic technology works by applying an electromagnetic pulse or “tap”
to the top of each container inside the sealed cardboard or shrink wrapped
case. The lid of the container vibrates at a natural resonant frequency
(“tone”) based on the internal pressure or vacuum in the container.
A microphone then senses the resultant tone. The system converts the
analog signal to digital and then the DSP board analyzes the output and
calculates the frequency. Containers outside user-set limits result in the
entire case being rejected. The magnetic pulse and acoustic response
will work through the cardboard or shrink wrapped cases. Defects
include low or no vacuum, low or no pressure, flat sours, dented lids
and missing containers in the case.

being rejected. The analog sensor will work through the cardboard
or shrink wrapped cases. Defects include low or no vacuum, Low
or no pressure, swelled cans, pop-buttons, dented seams or missing
containers inside the cases.

Case System Configuration
The T4000 Case system is a self-standing system that can be configured
as follows:
•t

Proximity inspection: 1-4 proximity sensor heads (single bridge)

•t

Acoustic inspection: 1-4 acoustic sensor heads (single bridge)

Proximity Technology

•t

Proximity technology works by measuring the curvature of each
container through the sealed case using analog proximity sensors.
The curvature for each container in the case is analyzed and assigned
a merit value based on the curvature measurements. The system
determines whether the container is acceptable or faulty based on userset parameters. Containers outside user-set limits result in the entire case

Combined acoustic/proximity inspection (one acoustic bridge
and one proximity bridge)

The system includes a six-foot inspection conveyor for warehouse or
other off-line applications. Spray markers can also be added (optional)
to mark the location of the faulty containers within the case for easy
identification and rework. The system can be ordered without the
conveyor for on-line applications.
