When plain old soap & water just don’t do the trick, there are a number of hand cleaners available on the market to remove even the most stubborn dirt & grime. Some are lotion-like, and leave your skin moisturized. Others have abrasive grit, and don’t. They come in all sorts of containers, too, from small jars that you dip a portion from, to large jugs with pump dispensers. The latter is oftentimes found in industrial repair shops…and they’re made on the production line of a company who needed our help getting rid of static charge.
After the extrusion process, these jugs are conveyed through a series of prep stations before they’re labeled & filled. The static charge generated along the way was causing issues with labeling: it made them skew one way or the other, or wrinkle up at certain points, instead of being applied straight & smooth on the side of the jug.
Now, all it takes to generate a static charge is contact and separation of non-conductive surfaces. Every time a roller sent a jug moving on the conveyor, or a bumper changed its direction, the static charge built up. In most applications, the best place to remove static charge is right before it becomes a problem. There was a tunnel immediately prior to the labeling station that was an ideal location to install a Static Eliminator…so they did.
The tunnel was 29″ wide inside, so this was a great fit for a Model 112224 24″ Gen4 Super Ion Air Knife Kit. Blowing ionized air across the jugs as they moved through the tunnel eliminated the static charge, and their label problems.
They also noted an additional benefit: this wasn’t a huge problem, but occasionally, a jug would have some plastic chips or shavings clinging to it. Those would get rejected during quality inspection…they’d have to remove those labels and put them back in the line. Again, it wasn’t a huge problem, and was within their quality tolerances…but they went to ZERO after they started using the Super Ion Air Knife.
If you’ve got a problem with static charge, EXAIR has a variety of solutions that’ll take of them, and perhaps even others. Through the end of February 2023, we’ll even give you a free AC Sensor with any qualifying Static Eliminator Product purchase. Give me a call if you’d like to find out more.
