The questions to ask when purchasing to avoid obsolete camera inspection systems

System Overview

The goal of this document is to review the inspection system technically and to identify future support issues. The diagram above shows the 4 key areas that are then surveyed in detail below.

  1.  Camera system
  2. LED Lighting system
  3. Image processing system
  4. Software

Why rollers are important parts of a 100% inspection system

Rollers are used to guide the web material along a predetermined path through a process
line. Let's take a printing press as an example. The path will vary on most presses as different
print jobs have varying print requirements (number of colors, cold seal, side of printing,
drying time, etc.). The web path will also vary depending on the drying times and drying
temperatures of the inks. Under the inspection head, rollers are used to present the web to
the cameras in as stable a condition as possible. There are a couple of configurations often
used for both surface inspection and print inspection.

Using a vision system to support process control, manufacturing and quality

When purchasing an inspection solution you must think about the end user. Often it is a project engineer that specifies a vision system for their surface inspection requirements, but does not consider how it works for all the key users who operate it daily.  Let’s look at the key stakeholders in a factory that interact with vision systems:

  • The operator - this includes the personnel at the process line and converting lines.
  • The engineer - this normally is the process engineer that is responsible for the
    operation and upkeep of the process lines.
  • The quality supervisor - this is the individual tasked with using the data to guarantee quality of goods and the interface between customer service and production.

Smart converting using inspection data for track and trace

100% inspection system work flows

When manufacturing discrete items like boxes of biscuits, pharmaceutical products, cans and bottles there has always been the capability to inspect and reject. This has been taken for granted. When operating in a roll to roll environment the challenges are quite different. It is not always possible to stop the line so when a defect is detected it will continue to the rewind and become part of the product to be shipped.

Learn how rollers and web handling affect your 100% inspection system’s performance

The following article explains the many reasons why rollers (idlers) and web material properties can adversely affect inspection performance especially for 100% print inspection. Let's understand exactly the effects of idlers and web paths on your vision system.

Why print inspection is a requirement for the plastic packaging industry?

Understanding the printing industry

The printing industry is estimated to be the 5th largest industry in the world with global annual sales of over $240bn Printing is a part of practically all consumer goods, from publications to product packaging and labels. Based on research conducted by the Association for Suppliers of Printing and Publishing Technologies, the total installed base of printing presses is estimated at approximately 50,000 multi color web-fed presses (publications & packaging) and 100,000 multi color sheet-fed presses.  The print inspection industry has targeted a single segment of the printing market, the packaging segment.

Using a robot to inspect screen printed automotive displays

SheetFlow is used  for an automated sheet inspection solution for automotive parts

The client was facing several challenges. The volume for these high end automotive parts was rising, the availability of skilled operators was dropping, and the consistency of inspection was an issue. The goal was to design an automated cell that would accelerate the inspection and improve productivity while reducing returns.

US Packaging giant upgrades vision systems that were obsolete

US Packaging giant uses PackFlow  to upgrade old presses

A major US packaging supplier approached the team at OneBoxVision with a challenge. The client had a stock of older presses equipped with vision systems that the suppliers would not support anymore. They were deemed obsolete. OneBoxVision surveyed the equipment and specified a state of the art upgrade using commercial off the shelf components that the user could source in the US. The target lines were equipped with a complete new set of vision systems at close to 50% of the cost of purchasing replacements from the incumbent suppliers. This allowed the client to spend more on training and  validation so as to ensure the equipment was used to it's potential.

New kit to build 100% print inspection systems for packaging

Can I build a  print inspection system?

The packaging industry continues to expand and automate.  When one looks at the high cost of turnkey camera solutions from industry providers such as BST, AVT and others, and the reduction in cost of components, building your own system  looks like an attractive opportunity. There is an opportunity for converters to lower CapEx costs and for other engineering companies enter a high margin vision niche.

Simple viewing camera added as key feature to ImageFlow

Low cost matrix camera added as integrated viewer on a printing press

Often an inspection systems resolution is perfect for automated feature detection, but an operator may need to see some items in more detail or have a different view. ImageFlow supports the integration of a simple matrix camera as a viewing option.

The example below shows how one was added to a printing press so operators could view tiny register marks in more detail.
