The Best Solution To Inspect Glass Containers - Whatever The Defect or Contaminant

Any company working with glass containers needs to inspect their product with X-Ray; even the most robust QA process cannot prevent glass shards from ending up in the final product. Even the best rinsing process is not enough – the only way to keep glass out of product is to thoroughly inspect every single container and remove contaminated ones. Couple ScanTrac X-Ray systems with our new advanced analytics tool Operations Guardian to gain powerful insight on vital metrics and continuously improve your operation.

The Best Solution For Glass: ScanTrac Trio

Glass containers represent special inspection challenges. Container shape and sizing can make glass difficult to inspect – glass jars have punts and are often irregular shapes and sizes. Triple Beam ScanTrac machines can completely inspect all aspects of the glass container and its contents because the side beams can “see around” the punt to inspect the entire container. ScanTrac systems can find a wide range of contaminants in glass containers, including but not limited to:

ScanTrac Trio
Superior Glass Inspection By Design

Outer Beams See Around Glass Walls and Push Ups

The illustration below demonstrates how a glass bead could hide in front or behind this region of a bottle. The high concentration of glass in this region would typically render the area worthless for inspection; however, as the illustration shows, what hides from one beam of the Trio lies in clear sight for another beam. Some glass shards and other foreign materials may be easier to detect from one angle vs. another. The Trio’s three beams provide a statistically significant increase in probability of detecting foreign materials in your product.

Precise Fill Level Inspection

The center beam of the Trio captures a head X-Ray image of the container, allowing for precise fill level detection. The difference in fill between the images shown below is less than 5 grams in an 8 ounce glass jar. The inspection area (dotted line rectangle bracketed by yellow dashed line) can be adjusted vertically and horizontally for optimal fill control.

Center Beam Inspects for Cap Presence

The cap inspection can be positioned precisely in this image from the center X-Ray beam to provide accurate missing cap control. The images below demonstrate Trio’s ability to detect the presence (left image) or absence (right image) of a container’s lid or cap.

Center Beam Eliminates Product Spacing Issues

For complete inspection of a glass jar using only two beams, the jars must be spaced. Even if the inspection is made after naturally separating systems such as labelers and cappers (or even when jars are transferred to an accelerated conveyor), the jars may move close to another jar and eliminate the typically required half diameter spacing. When containers are inspected without adequate separation in a dual beam system (see red circle above), the images are combined, creating an “overlapped” image as shown below. This condition can be detected by the X-Ray system but the inspection is incomplete. With only two images, the options the user has are to either a) accept all overlaps, or b) reject all overlaps. With the Trio, an assured inspection is always provided.

ScanTrac Minimizes False Rejects

The best inspection systems need to both find defects when they occur and minimize false rejects. False rejects are expensive not just due to the loss of salable product but because of the labor allocated to addressing them.

ScanTrac minimizes rejects because it offers an exceptionally repeatable inspection process that is not sensitive to temperature, humidity, condition of product, etc.

In many applications the false reject rate on ScanTrac systems is on the order of 1:100,000!
