So, the call came in about mid-morning – an operator at a facility that fills plastic jars with peanut butter needed help with an application…
And I almost got stuck thinking about peanut butter. I like food, and peanut butter is near the top of my list. I’ve seen it successfully applied to cheeseburgers, and the peanut butter & bacon sandwich is even a breakfast staple in some of the Boy Scout groups I’ve been involved with. Crunchy or creamy, peanut butter rules.
Now, I’m a pro, so I didn’t allow this digression to supplant the attention I was giving the caller. The application was simple enough: the nozzle feeding the jars retains a small amount of the product at the tip, which drips off when it’s good & ready, thank you very much. This is oftentimes when the jar is in motion, so this little glob falls right onto the rim of the jar, causing issues with the protective seal, and a continuing mess as this jar with peanut butter on the outside of it travels down the line.
Many times we will be contacted by clients who provide vision inspection systems for a variety of industries. These companies are involved in applications to inspect everything from part conformance to product counting to processes to filling applications.
In the first photo above a customer had their vision inspection system set to inspect the filling of a powder material into its container. The problem is that the fine, dusty nature of the product would cause a small cloud to form near the filling point which would end up settling onto the lens area. Over time, so much build up would occur that the vision inspection system was rendered useless.
The customer had a small air jet set up as shown in the photo on the left, above. The problem with their air jet was that it did not provide full coverage across the width of the lens and allowed dust to still settle there. You can see it in the photo. After the customer contacted us and described the situation and the size of their lens, we recommended model 1122 2” Flat Super Air Nozzle with the thinnest shim available which is .005” thick. The 2″ Flat Super Air Nozzle was able to provide an airflow that covered the full diameter of the lens and blast any debris away. In the end, they removed the homemade small air jet assembly and simply blew air across the lens with EXAIR’s nozzle. See photo on the right above.
Vision inspection cameras, lasers, and sensors are found in a variety of dusty and messy environments. Inspection systems on filling lines, sawing applications, weighing machines and grinding applications are just some of the notoriously problematic processes. If you are involved in a process that has trouble keeping the vision inspection lenses clean, the 2” Flat Super Air Nozzle is a great way to mount an engineered solution that won’t run you out of house and home on your compressed air usage. And best of all, it actually does a good job. If your application is slightly bigger, smaller, dirtier etc., EXAIR’s unmatched selection of nozzle and blowoff products can likely provide a solution.
