Generally, when we’re talking about a Line Vac application it involves the transfer of bulk materials from one place to another. Many applications involve replacing what we call a “bucket and ladder” operation. An operator must fill a bucket or container with the material, climb up a ladder, and then deposit it into a hopper. While this is a great example of one way to use them, Line Vacs can also be used in a variety of other applications.
In the past, we’ve blogged about using smaller Line Vacs for conveying yarn or string. At the end of a run there’s often too little thread left on a roll to save for a future run. The customer must strip the yarn off the remaining spool in order to reuse it. Using just a small amount of compressed air, a 3/8” Line Vac makes quick work of any residual thread on the spool.
I recently worked with our distributor in Argentina on another unique Line Vac application. Their customer manufacturers a variety of different types of protective plastic mesh. They come in many different sizes and colors and are used to protect the outsides of parts or products during shipping. Their machine required an operator to keep a close eye and at times manually feed the material into the machine as it would get stuck. Their hopes were to automate this process so that they could increase production and alleviate the need for an operator to worry about feeding the material by hand.
Using a Model 6082 1-1/4” aluminum Line Vac fitted with a funnel on the intake side, they were able to convey the plastic material into the cutter. It was cut to length and deposited in a box below. The video below shows the process.
The material is fed off of the spool and into the cutter without jamming or getting bunched up. Production rates are now consistent and they were even able to increase the feed rate by almost 20%. The 6082 consumes just under 26 SCFM of compressed air at 80 PSIG, making it a low-cost solution to what was an aggravating problem for them. In addition to the ability to increase the feed rate, automating this process freed up an operator to monitor additional processes in the facility.
