OmniVision II Empty Bottle Inspection

 

Sees it all so you know it all
The OmniVision II Empty Bottle Inspector is the only all-surface empty bottle inspector that provides full 360 degree inspection at line speeds up to 1400 bottles per minute – while exceeding all industry standards for quality, repeatability and reliability – with minimal false rejects.

 

Low-Cost and Simple Installation

The Omnivision II system is compact, modular, easily expandable and fits into existing lines without modifications, while machines by others require complex conveyor controls and additional conveyor transfers to ensure bottles are gapped before, during and after inspection. The OmniVision II requires no special gapping or controls, and can also deal with product back-up from fillers, unlike other systems.

 

Guaranteed Alignment

filtec’s unique vacuum Starwheel provides guaranteed inspection alignment by holding bottles in two places for perfect registration in the inspection zone – as opposed to relying on spongy belts that can collect contaminants and require frequent replacement. Additionally, a wide range of bottle sizes and dimensional tolerances can run through the OmniVision II without causing jams or stoppages.

 

Ultra High 360 Degree Performance
Equipped with the Auto-Rotator OSW system, the OV-II is the only true all-surface empty bottle inspector, providing a full 360 degrees of sidewall inspection. Bottles are rotated while passing a high-speed camera where up to 12 images of the entire outside surface of every bottle are captured for complete coverage. State of the art multi-media technology processes it all.
The OmniVision II features the highest speed digital processing and reject handling that is independent of other computing systems – so it can’t be slowed down by typical CPU technology. It also features Integrated Fail-safe Rejection, so if air or power is lost, all bottles are automatically forced onto the rejection conveyor instead of going uninspected to the filler.

 

Inspection types include:

  • Base
  • Inner Sidewall
  • 360° Outer Sidewall
  • Residual Liquid
  • Finish
  • Thread

The OmniVision II addresses an impressive range of empty bottle problems, including contaminants, foreign objects, transparent film, glass defects, residual liquid, glass damage and scuffing .
Leap ahead of industry standards with the OmniVision II – the only empty bottle inspection system that has true full coverage.

Base Inspection

A high-speed camera captures high contrast images of the base and heel of each container using specialized LED lighting and optics. Empty bottle inspection algorithms filter out normal features of containers such as bottle design and embossing, and then identify contamination or damage on the inside and outside of the container. System software divides images into as many as six overlapping user-defined inspection zones. Even cellophane can be detected with the Bright Field option. Special optics and filters assure optimal empty bottle inspection with minimal false rejects.

 

  • Bright Field Option
  • Residual Liquid/Caustic Detection
  • Thread Inspection
  • Inner Sidewall Inspection
  • 360° Outer Sidewall Inspection
  • Finish Inspection

 

    The bright field option utilizes the standard base inspection camera with a polarization system to detect transparent cellophane that is not detectable by the human eye. The system causes the cellophane to appear as an opaque object so that it is easily detected by the camera optics and analytic software. The bright field process is superior to dark field analysis which requires a separate camera system.

    Residue left from the washing process poses a high risk to the quality of the product. The OmniVision II identifies this residue with two different inspection options:

    Residual Caustic Detection

    The filtec residual caustic detection system generates a high frequency radio signal in the base area of the container which is measured by a receiver on the other side of the container. Even a single drop of caustic carryover or dry caustic film is reliably detected by the change in the signal.

    Residual Liquid Detection

    The filtec residual liquid detection system detects even the smallest amount of water based liquids in containers by measuring the amount of absorption of infrared radiation by the container. (Illustrated below)

    Damage to the thread of a bottle top can prevent proper closure or make it difficult to open the container. In addition, sharp edges, chips and cracks can cause injury to customers.

    The OmniVision II inspects twist and roll-on-pilfer-proof (ROPP) thread of containers using a top view camera, LED lighting and special custom optics to focus the camera on the thread, and a dedicated high speed image processor for full thread inspection

    The thread inspection evaluates up to 720 degrees of roll thread and inspects the full length of all twist thread segments, providing both thread integrity and thread “unwrap” evaluations.

     

    The OmniVision II inspects the inner sidewall of containers by looking through the necks, allowing it to detect contamination on the inside of the container behind ACL labels and even heavy scuffing.

    A separate camera uses optics specially designed to capture images of the inside walls of each container. Additionally, the OmniVision II performs a secondary base inspection while it performs the inner sidewall inspection. Special object detection provides the ability to detect syringes and other large objects – allowing these types of rejects to be segregated from other rejects using a downstream sorting system.

    Front view inspection is the only way to be assured that containers are not damaged and no foreign objects or contaminants are present. This is especially true when inspecting dark glass and containers with fluted and embossed features – where visibility of the far side is obscured by the color and texture. The OmniVision II is the only all-surface empty bottle inspector that provides full front view inspection by taking up to 12 separate images of each container as it continuously rotates through the inspection area.

    The ability to analyze 12 separate images of each bottle makes it easier to distinguish between normal design features and contamination or defects – providing more accurate inspections and reducing false rejects.

    Sophisticated software divides each of the 12 images of each bottle into multiple overlapping inspection zones and filters the images to differentiate normal bottle characteristics from defects or contamination. It then compares the results of each of the images to further differentiate defects from normal bottle characteristics.

    Damage to the sealing surface or finish of a container can jeopardize the quality of the product by preventing a good seal which can present safety hazards to customers.

    The OmniVision II uses sophisticated optics, LED strobe lighting and field-proven image processing algorithms to analyze the entire sealing surface and adjacent areas and reliably differentiate between critical faults (chips, cracks, etc.) and signs of normal wear in finishes. Its “Dual” lighting system allows for the reliable inspection of different types of container finishes – e.g. crown and thread, within one inspection station.

    The OmniVision II inspects bottles up to 70 mm in diameter.
