Inspection 4.0 for converters
The converting factory normally starts with a substrate. This can be paper , film, foil or sometimes a non-woven. More often than not it’s plastic film. Our software is designed to inspect rolls or sheets of plastic. Usually a converter will pass the substrate through some other value added process, whether it’s printing, laminating, perforation or pouching. Sometimes it can be all of them.
- SurfaceFlow – surface inspection algorithms for film, paper, foil and non wovens
- PackFlow – print inspection for flexible packaging with advanced classification
- Veriflow – Tool used for preprint operations to check printed products against designs
- Opacity analysis – used to measure the density of extruded film
- Color analysis – measure the color of pigmented film
- Seam verification – inspect the quality and integrity of seams on a roll
- Perforation verification – Verify location and number of perforations
- Caliper – measure the width of substrates
- AutoTrack – measure eye mark to eye mark to detect excessive stretch
- CodeID – 1D and 2D code verification with support for serialization
- Rewind Manager – Work flow that enables waste removal
- Fiber orientation – Non woven fiber randomness verification
- Smart converting starts with measurement and improvement. To accomplish results that enhance your process it is necessary to integrate the solution and use the data.
- ImageFlow supports data storage to commercial cloud suppliers and to standard industrial historians. OneBoxVision offers analytic data dashboards using industry standard business intelligence suites.
Inspecting the extruded substrate
All plastic film include some level of contaminates, arising from the production process or due to the nature of polymers. Extrusion and converting lines classify many defect types such as gels, black specs, fish eyes, holes, oil stains, insects, scratches, coating voids, air bubbles etc. These all originate from different issues but most all can have an impact on the further processing.
SurfaceFlow will locate all defects and identify the exact position, take a snapshot of the defect and alert the operator in real time. The end result is to avoid the production of waste. You can see benefits of deploying inspection in a number of areas including the film extrusion and converting process, the incoming raw material or at the final product especially during converting. By providing real time feedback on gel and black spec contamination, the machine downtime for die cleaning can be reduced and its capacity enhanced.
Gels or Fish-eyes are small film defects are normally characterized by their area and protrusion above the film surface. A gel count is one of the standard film properties. Foreign polymeric materials that do not completely melt form gels. Contaminants such as dust from bulk containers, particles and foreign materials, e.g. from poorly cleaned silos, can also cause fish-eyes. During the transfer of PE pellets through pipes, some of the PE pellets melt and smear on the walls and form ribbon-like streamers (angle hair) that flake off into the pellet stream. While the streamers are still adhering to the walls, their large surface area comes into prolonged contact with atmospheric oxygen. This can form fish-eyes. Deposits on the inside wall of the extruder and prolonged thermal exposure during a stoppage can also lead to fish-eyes with brown spots.
OneBoxVision’s System enables the control of film quality during production. We analyze material defects and provide real time feedback for the operator. It documents the quality of the product and supports the operator with the optimization of the production process. It guarantees total quality control and monitors key metrics..........
