In parts one and two of this blog series, I described the typical packaging process, how actual runtime is defined, how vision is used to improve runtime, and how vision compares to the use of discrete sensors. In this last installment of this series, I will show some specific examples of how vision sensors have been used in packaging and show two case studies exemplifying the benefits customers achieved with the use of vision in their processes.
In my recent travels of the east coast from Boston to Tampa, customers have been looking for quality solutions to be able to run:
and multiple sizes,
and multiple form-factors,
all on one production line.
Two things about this seem to be in every application:
- Change-over needs to be simple for the operators.
- Management needs to see the cost/time savings, be it planned or unplanned downtime.
But how can I do multiple recipes or multiple jobs on one machine? I have to reprogram/reposition sensors, move guide rails, swap out components, etc…
In part one of this blog series, I described the basic definition of the typical packaging process and how many processes runtime actually get broken down and defined. In this second part of vision sensors in packaging, I will specifically describe how vision is used to reduce planned and unplanned downtime and compare discrete versus the use of vision to achieve the same goals of error proofing a process and runtime improvement.
One of the things I am often asked about is “why use machine vision in packaging”? There are many reasons, including dealing with the perceived complexity of serviceability and cost. I will show you where the use of vision in packaging can significantly decrease a major cost factor called “planned downtime”, along with other benefits in this 3 part blog series – so stay tuned for my later posts.
