Filtec
Empty Glass Bottle Inspection

Catch imperfections in glass containers of all sizes before they reach the filler.

Empty Glass Imperfections

Imperfections in empty glass containers, either returnable or even straight from the manufacturer, can easily result in damaged or wasted product. Empty bottle inspection occurs between the washer and the filler, ensuring that no residual liquid, foreign objects, or damaged glass comes in contact with the product.


Common Glass Flaws

  • Damaged glass
  • Cracked thread
  • Scuffed sidewalls
  • Residual liquid or caustic
  • Chipped base
  • Uneven finish
  • Foreign objects

OUTER SIDEWALL INSPECTION

Outer sidewall refers to the outside surface of a container, usually below the thread and above the base. This outer surface can often become visibly scuffed or chipped, especially in returnable glass or PET. While outer sidewall damages are unlikely to corrupt the product itself, external container flaws are the indications of low quality standards most obvious to the end consumer.

Inspection Technology Overview

  • 15 independent inspection zones
  • ACL detection
  • Adjustable illumination
  • 360 degree outer surface inspection
  • 6000k LED panel strobe
  • Cellophane / brightfield detection
  • Adjustable illumination
  • High resolution images
OUTER SIDEWALL INSPECTION

Sidewall Bottle Rotator

Twelve images are captured at 30 degree intervals while the bottles rotate past the inspection window, providing the most thorough inspection and fewest number of false rejects.

Bottles rotate against each other as they pass through the inspection field, allowing for 360 degree detection.
LED strobe passes high intensity light through the empty containers to a high speed digital camera where an image is captured and processed through a series of algorithms.

BASE INSPECTION

The base of a bottle receives the most amount of wear during the container's life, and easily sustains scuffing or chips. Thorough inspection of both the inside and outside of an empty container's base prevents flawed packaging and contaminated product from reaching the market.

Inspection Technology Overview

  • High resolution CCD camera
  • Detection of flaws both inside and outside of the container
  • Adjustable filters for embossing and varying bottle designs
  • Up to 6 different inspection zones
  • Adjustable filters for embossing and varying bottle designs
  • Cellophane / brightfield detection
BASE INSPECTION

INNER SIDEWALL INSPECTION

The bottle's inner sidewall is made up of all the inside surfaces from the base up through the neck. Damages in these surfaces can be difficult to see with the human eye, but can easily grow mold internally or shed glass into the product after it has been filled.

Inspection Technology Overview

  • High resolution CCD camera
  • Detection of flaws behind ceramic labels or embossing
  • Up to 6 different inspection zones
INNER SIDEWALL INSPECTION

THREAD INSPECTION

A bottle's thread refers to the molding at the top of the neck where the cap may be screwed in place. Incorrectly formed or damaged thread can result in capping failures, spillage, and contaminated product.

Inspection Technology Overview

  • High resolution CCD camera
  • Up to 720 degree inspection tracking
  • Adaptable for Press, Roll, and Twist finishes
  • 5 inspection zones
  • Auto-centering and auto-tracking functions
THREAD INSPECTION

FINISH INSPECTION

The finish of a bottle or container is the very top surface where the cap is applied. For returnable glass especially, this surface can easily chip while in the market or during the washing process and cause problems with proper capping and sealing. If a chipped finish does make its way back out into the market, sharp edges can harm the end consumer.

Inspection Technology Overview

  • High resolution CCD camera
  • Long-life LED strobe
FINISH INSPECTION

RESIDUAL LIQUID & FOREIGN OBJECT INSPECTION

Without additional inspection, leftover caustic and objects (like mold, cigarette butts, or straws) not shaken out during the washing process can remain inside of returnable containers through the filler and get sent back out to the market.

Inspection Technology Overview

Radio Frequency (RF) RLD Technology

Detects smallest amounts of caustic, even once it has dried.

Infrared (IR) RLD Technology

Detects oil, paint, gasoline, and other liquids and objects with low conductivity.
