Adjustable Air Amplifier Transfers Plastic Bag Scrap

Many times EXAIR products are used to help sort materials based on their weight or their density by providing a consistent force against a series of targets that should be of the same density or weight, but when they are not, the airflow can be “tuned” to remove the non-conforming parts.

Model 6042 Aluminum Adjustable Air Amplifier rejects empty pouches.

In this case, our customer (a packaging automation specialist) was working with a form fill and seal machine that was dedicated to making pouches 2” x 8” and filling them with a food product. In some cases, the pouches would not become filled with product and needed to be removed from the line. So, our customer devised a way to mount model 6042 2” Adjustable Air Amplifier along-side the travel of the pouches and set the input pressure and air gap setting to get optimum vacuum capture velocity to suck away empty ones and leave the full ones in-tact. Above you can see a photo that the customer took while mocking up the application at their facility. You can see the hose connected to the output to direct the empty pouches to a wire basket below.

A couple of things in this application made use of the Adjustable Air Amplifier the best choice. The first was the funnel-shaped suction area on the back side of the Adjustable Air Amplifier. This optimizes the Air Amplifier’s ability to draw in ambient air to propel it to the outlet. In doing this the un-filled, light-weight, plastic pouch becomes caught in the high velocity stream and thus gets carried away as desired. The second thing is that since compressed air is the source of power, the customer has infinite adjustability over the amount of suction force that they can apply to the pouch in the application. They can adjust the air gap opening on the Adjustable Air Amplifier to have a coarse adjustment of air consumption as well as vacuum level. Then, they have a finer adjustment that a pressure regulator can provide to really dial in the suction force as they need it to be for removal of the empties.

The idea here is that while Air Amplifiers are generally used for their output flow to cool targets and provide a significant Blowoff force, they can also be used to draw in not only smoke and fumes but also other lightweight items like the empty pouches above.

If you have a need to set up any kind of sorting process, maybe just to separate two different recycling streams or perhaps it is a need to perform a quality control function as shown above, think about EXAIR and our many solutions in this area.

Adjustable Spot Cooler Provides Needed Cooling In Sunglass Lens Manufacturing

A little while back, I worked with a large eyeglass manufacturer on a sunglass lens cooling application. In their setup, they were dry cutting film-coated lenses with a router and after the lenses are cut, they are passed through several different rinse cycles and inspected for scratches or other damage. They were seeing a high number of reject parts and determined that the heat being generated by the tooling, was causing the irregularities. In an effort to alleviate the condition, they used a section of open flexible tubing to blow compressed air at the bit, which helped a little, but they were still concerned with the amount of scrap material.

I recommended they use our Model # 3825 Adjustable Spot Cooler System in the process. The Adjustable Spot Cooler incorporates a Vortex Tube to provide a temperature drop from the incoming supply air temperature. Using the temperature control valve, the exhausting air temperature and flow can be adjusted to fit the application. The system includes a flexible hose to focus the cold air to the desired area until re-positioned. The system also features a magnetic base that allows for easy mounting. By incorporating the filter separator included in the system, they can remove any moisture and/or contaminants in the air supply, relieving any concern with contamination or damage to the part.
