EXAIR E-Vacs For Pick-And-Place Applications

EXAIR E-Vacs For Pick-And-Place Applications

One of the topics which is sure to produce good conversation is our vacuum generator product line, the E-Vacs.  Using a compressed air powered venturi to produce vacuum, the E-Vac is attractive for a number of applications because the vacuum flow is instantaneous.  This means we can produce vacuum only when and where it is needed rather than keeping a vacuum pump in continuous operation.

Power supplies to be lifted with EXAIR E-Vacs
This instantaneous nature of the E-Vac was recently attractive to an end user in need of a better method to handle electronic power supplies used in their computer production process.  They wanted the lifting and placement of the power supplies to be semi-automated, with an operator turning the lifting system on and off.
This type of application is perfect for an E-Vac.  In order to determine the best solution, for this or any E-Vac application, we have to first determine the following:
  1. Is the material/item to be lifted porous or non-porous?
    1. Porous materials will have leakage through the material itself, or through inconsistencies in the material surface. Items such as cardboard, fabrics, or a golf ball are considered porous.
    2. Non-porous materials will not have leakage through the material. Items such as smooth glass and flat plastics are considered non-porous.
  2. What is the weight of the item to be lifted?
  3. How will the item be lifted?
    1. Will the vacuum cups mount to the top of the workpiece to the side? This will determine if the suction cups will be in a horizontal or vertical plane when lifting the product.
Battery dims
Dimensions of the workpieces
Using this information we can determine the proper safety factor to apply (2 for horizontal orientation of the vacuum cups, 4 for vertical orientation), and the potential vacuum cups to be used.  Then, based on size of the workpiece and space constraints we can select the proper vacuum cups.  And finally, using charts on file with the EXAIR Application Engineering department, we can select the correct E-Vac or E-Vacs for the application.
If you have a pick-and-place need in your facility, contact an EXAIR Application Engineer.  We’ll be happy to help choose the right components for your setup.

Super Air Knife Protects IR Camera Lens


2016-02-25 10.24.50
The blue compressed air line feeds the Super Air Knife used to keep a camera lens clean.
Exair's German distributor, Eputec Gmbh contacted Exair person one day regarding a customer they have been working with to supply 3” Aluminum Super Air Knives for keeping an infrared camera lens clear. The mentioned cameras were supplied with an “air ring” of sorts from the manufacturer, but they consumed a good deal of air and were not effective for the task of keeping the lens area with a clear view of the process it was intended to monitor.
With that, the end customer wanted to improve on this characteristic of their equipment. And so they contacted the technical specialist at Eputec Gmbh to discuss options. After determining the need, they chose a Model BP110003 (3” Aluminum Super Air Knife) to blow away the smoke and other light debris that can tend to float into the view of the camera. A photo of one of the IR cameras with Model 110003 fitted along with a heat shield and an automated lens cap to keep the lens clean when not in use.
Blowing lenses of cameras, sensors, lasers and other similar devices used to monitor process and provide feedback has been one of the more common uses for the Super Air Knife over the years. If you have a similar process that could benefit from using Super Air Knives, contact us and we will be glad to render the same quick service to help you through your application.

Ion Bars Eliminate Static in Foam Web Production

10. STATIC
Foam Web with ineffective Earth grounding
Exair's Greek distributor came to Exair one day with a production issue for one of his clients. They manufacture foam in a variety of forms for many different end uses. In this particular case, the customer was working with a flat web of foam. As they are un-rolling and processing the foam, a decent amount of static charge builds up on the material which eventually causes discharges to the rollers in the machinery and to operators as well. The discharges are dangerous to personnel as they can be quite potent, causing a reflexive jerk back which can put the operators into a dangerous position with respect to machine components, not to mention that they are just flat out uncomfortable to receive. Another issue is that the discharges also cause blemishes on the surface of the white foam where they occur. Such blemishes are considered a defect and are therefore another reason that the customer wants to investigate active static elimination.
As you can see in the above photo, the customer has a couple of ground “probes” if you will, that ride on the surface of the foam web. They do this in hopes that the charges will “drain off” to Earth ground. While this kind of “passive” static elimination can be useful in certain circumstances, many times is just not sufficient to completely neutralize the material as needed for the process. Exair reviewed the line speed in the application and the web was moving at a reasonably slow 10 – 15 meters per minute. With this in mind, the EXAIR Ion Bar would be a perfect fit to provide the necessary ions to “actively” discharge the electrostatic field. By actively, I mean that the ion bar produces positive and negative ozone ions which are actively delivered and come into contact with the material. This causes the net charge to drop to a much lower level than simple grounding techniques just cannot get to.
Exair ended up recommending two pieces of model 7042 (42” Ion Bar) (one for each side of the web and model 7907 (2 outlet Power Supply, 230 VAC input) for the application. These bars have eliminated the blemishes on the foam web and removed the static shocks experienced by the operators.
With the very coldest of winter-time temperatures upon us now, it is what Exair term “static season” due to the low humidity in the air. Processes like this one can be rendered hopeless without the use of some form of active static elimination.
Are you in a converting business of some kind? Do you have static issues in your processes?  If so, consider contacting us for some help with your application. Static electricity in a production environment does not have to be a problem.

3″ Super Air Knife & 1″ Flat Super Air Nozzle Solve Bearing Measurement Inaccuracies

A bearing manufacturer was having an issue effectively removing oil from a bearing race prior to a laser micrometer for gauging dimensional tolerances. The bearings are assembled, travel through a washer and then go through a centrifugal dryer. After the dryer, the bearings travel down a conveyor to the laser micrometer, where they are measured, laser marked, coated with rust preventive and boxed for shipment. The issue they were having is after the centrifugal dryer, they were still seeing small droplets of oil and contaminants settling on the outside diameter of the outer ring, causing the laser to take a faulty reading which would reject part.
Bearing
Example of a caged bearing.
Exair recommended the customer mount a 3″ Super Air Knife over the top of the conveyor and a 1″ Flat Super Air Nozzle mounted vertically on each side to allow the bearing to pass through a “tunnel” of high velocity air to remove the foreign matter. While this would solve the contamination issue on the O.D. of the bearing race, it raised another concern to the customer. The laser takes the reading through a small slot on the side of the conveyor, and with the particulate being airborne again, the customer was concerned they may see some contaminants work their way through the opening and settle on the laser lens. The opening is about 3/4″ so I recommended they install another 1″ Flat Super Air Nozzle to blow across the small opening, making a curtain of air to block any foreign matter from passing through the slot.

This is just one example of using multiple EXAIR products to solve a single issue. Whether it’s a contamination blowoff application or something entirely different like cooling, exhausting fumes or conveying product, chances are EXAIR has a solution. Give us a call to see how we might be able to improve your process.

Remove Irritants in the Work Place


Saving Money and Compressed Air
Save Money, Reduce Noise, and Minimize Compressed Air Use
We are having a mild winter in Cincinnati, Ohio, and even though the poison ivy seems dead, you can still catch it. One lady was collecting brush, and in two days, she broke out.  She had a rash on her arms, legs, face, and stomach.  And if you ever had poison ivy, you know how itchy it is.  The problem is that if you itch it, you can spread it.
It started Exair's people to think of things that are a nuisance in manufacturing, like noise exposure to personnel and wasted costs within processes. The Intelligent Compressed Air Products by EXAIR can reduce noise levels and electrical costs.  One very simple exercise would be to locate all your open pipes that use compressed air.  They can be located on machines to blow off debris and even on the end of air guns.  For every open type pipe, place an EXAIR Super Air Nozzle on the end of it.  You will notice very quickly that the noise level is reduced.  It can drop the noise by as much as 40 decibels.  The other thing that you will notice is your monthly electric bill.  By adding our Super Air Nozzles to the end of your inefficient blow off pipes, you can be saving over $1,000/year for every open type pipe.
If you have poison ivy, I would suggest calamine lotion or here are some additional tips. If you have high noise levels and high energy costs, then I would suggest EXAIR products.  You can discuss how EXAIR can save you money and reduce your noise level by contacting one of the Application Engineers at EXAIR.

Cooling Fabric with a Super Air Knife Increases Production Speed

Super Air Knife has 40:1 Amplification Ratio
Super Air Knife has 40:1 Amplification Ratio
Exair received a call from a customer in the textile industry. The customer was producing a fabric that ends up being used for furniture.  The fabric varied in width between 4 feet (1.2 meters) and 6 feet (1.8 meters) wide.  In one of the processes, the material went through an oven to be heated to 200 deg. F (93 deg. C).  This would “set” a fire retarding chemical compound in the fabric.  As the fabric web exited the oven, they needed to cool it to roughly 120 deg. F (49 deg. C) so it could be handled by the operators.
The customer tried their luck at designing a duct that was seven feet (2.1 meter) long by one foot wide (30.5 cm) by one foot tall (30.5 cm).  At the bottom of the duct, they cut one inch wide (2.5 cm) slots along the length in an attempt to create a wide airflow across their material.  The large metal box (ducting) was suspended across the fabric and oriented to blow air straight down onto the material.  On the open end of the metal box, they mounted a fan to blow air inside with the intention that the slits in the duct work would direct the air from the fan onto the fabric.
Their idea worked to some small degree, but the cooling results were simply too little to continue with this kind of solution. Fortunately, the customer knew about EXAIR Corporation and they contacted us to see if we could help. Because they needed to provide additional time for the fabric to cool, they slowed their line speeds down to 20 yards/min (18 meters/min). It was obvious that they wanted to increase the throughput if they could.
In order to increase throughput, we needed to figure a way to increase the cooling rate.  To increase the cooling rate, we can either use colder air or more air.  Given the wide format of the material, the best decision for this application would be to blow more air across the target material.  The Super Air Knife has a 40:1 amplification ratio.  For every 1 part of compressed air, it will entrain and move 40 parts of ambient air to the target surface.  The result is that a larger volume of air hitting the surface of the material.  More volume hitting the target means we can cool it quicker.  I suggested a model 110272, 72″ Super Air Knife Kit to span across the different width of fabrics.  It can be mounted across the width of the material and set at a 45 degree angle to the material in a counter flow orientation. The reason for the angle and the counter-flow orientation are to enhance the cooling effect provided by the Super Air Knife. Orienting the Super Air Knife at a low angle allows for the flow coming from it to stay in contact with the material web for a much longer period of time.
By removing the fan with the duct work and installing the Super Air Knife, they found they could increase throughput to 30 yards / min. (9.2 meters / min). A 50% increase. The customer was thrilled about the significant increase as this was a real bottleneck in their production process.
If you have any cooling issues, you can rely on Vivek Engineers to determine the best product. If you have any questions or would like to discuss any of your applications, you can contact the Application Engineers at Vivekengineers.

When Your Best Salesperson Is A Cabinet Cooler System


Recently Exair had the pleasure of assisting a customer with an Air Knife application.  It wasn’t the “textbook” blow off situation, but it was another fairly common use: environmental separation.
That’s the fancy term for keeping liquids, gases, fumes, etc. inside a machine or enclosure, and/or away from personnel or equipment that might not function properly when exposed to said contaminants.  In this particular situation, they just wanted to keep coolant spray in a CNC machine away from the lens of a vision inspection system’s lens, inside the machine.  Our Super Air Knives are so good at this, they’re even used in the motion picture industry to keep droplets off the camera lens when filming scenes where water is being sprayed everywhere…just like the coolant spray inside a CNC machine.  So they purchased a Model 110206 6″ Aluminum Super Air Knife Kit to blow a light curtain of air in front of the lens.
Now, we know that’s a nice little blog, all by itself, but it’s an application that might not have stayed in my mind much longer than the time to process the order, had it not been for an additional detail from our conversation:
They called because they were very happy with our Cabinet Cooler Systems.
Which they installed on some control panels in their machine shop, years ago, and were famously preventing electrical component faults where the refrigerant-operated coolers had failed.

THIS is where excellence in customer service, quality manufacturing, error-free and on-time shipping (99.997% on time for 17 years and counting) make ALL THE DIFFERENCE…it gets you remembered the next time a user has a question about something that might be related to something similar.  And in this case, the only similarity was that both products are compressed air operated.
When you think of compressed air, we want you to think of EXAIR.  And it appears to be working.  we are proud to be here, and I eagerly await  your call to find out how we can provide a solution to your compressed air question or concern.

Proper Air Supply & Installation Provides Best Performance

Exair was recently contacted by a customer who was using (2) of our 18″ Standard Air Knives to keep a sealing surface clean on their leak test fixture during a welding operation. The customer didn’t have a blow off in place before using our Air Knives and saw considerable improvement but were still seeing some residual contaminate on the sealing surface area. Their first thought was to turn up the pressure on the supply in an effort to create more flow, and while this did provide a slight improvement, the end result was similar. Next they were considering ordering a shim kit which includes a .001″, .003″ and .004″ shim, with the thought that opening the gap in the air knife, they would achieve more flow. (The Standard Air Knife is shipped with a .002″ shim installed). While changing to a thicker shim will provide additional force and velocity, we generally don’t need such large shims to blow away dust and light liquids from a surface. I turned our focus to the compressed air supply lines feeding the knives.
The customer was able to send a few pictures which quickly explained the lack of performance:

Photo 1
In the above photo you will notice the undersized 10mm tubing the customer was using to feed the knives. For an 18″Standard Air Knife we recommend 1/2″ Schedule 40 Iron Pipe for a run up to 10′. Using undersized lines and/or restrictive fittings starves the knife of air volume and will result in a pressure drop which reduces the performance of the Air Knife. They were also using a standard pipe nipple coming off of the other end inlet of the first Air Knife to supply compressed air to the second Air Knife. This type of setup would actually starve the second knife even more as there wouldn’t be enough volume or pressure being delivered for the unit to perform. With the 10mm tubing effectively trying to feed (2) knives, this only compounded the inadequate supply for the air demand of (2) 18″ Standard Air Knives.

Pic 2 EDIT.jpg
Photo 2

Referencing Photo 2 above, the customer was using our 3/4″ Pressure Regulator, Oil Removal Filter and Filter Separator and also supplying them with the 0mm tubing. To maintain their pressure and volumetric flow (SCFM), they would need to increase the supply size to at least 3/4″ pipe or larger. The other concern is the installation itself, with the airflow running from left to right in the image above – the filters should be mounted in line before the pressure regulator to provide clean filtered air to the regulator and accounting for any pressure drops passing through the filters.
The customer advised they have submitted a work order to have the filters placed in front of the regulators and to replace the supply line with 3/4″ pipe. Once the installation is correct, they will quickly learn that EXAIR air knives are the best in the industry and will have a successful application.

Cold Gun Aircoolant System

Adjustable Spot Cooler









Replace messy mist systems - improve dry machining with clean, cold air!


What is the Cold Gun Aircoolant System?

EXAIR’s Cold Air Guns use filtered compressed air (80-100 PSIG) and vortex tube technology to produce sub-zero air for industrial spot cooling. Using only compressed air, the Air Gun produces a stream of cold air 50°F (28°C) below your compressed air Cold Guns keep parts cooltemperature @ 80 psi. It’s clean, convenient – put the gun where you need it, using the magnetic base – aim the cold air stream onto your work with the flexible hose – go to work!. To optimize the gun’s cooling capability the cold airflow & the temperature drop are factory set & is non-adjustable.
Cold air machining eliminates mist coolants and heat-related parts growth while improving tool life, parts tolerance and surface finish quality. Air Cooling System for dry machining applications - replaces polluting and often toxic mist systems to improve dry machining operations. No mess, no residue and low in cost. The unit is muffled for quiet operation. No moving parts assure long life, maintenance free operation while extending tool life and improving production rates.
Cold Air Guns are used in various industrial processes, fabrication, assembly and packaging as a versatile spot cooling device. Most popular applications involve cooling during the machining of metals, plastics, wood, rubber, ceramics and other materials.

Super Air Knife Helps Keep a Belt Clean for a Cement Factory

PKI
A cement factory was having some issues with spillage of cement powder underneath his conveyor. This 48” wide conveyor system used a cleated belt to carry the cement ingredients up an incline to a mixing chamber.  As the conveyor went around the end to dump the mix, some of it would stick to the cleats and corners where the cleats were attached to the belt.  At the conveyor return, any ingredients that were sticking to the belt would dislodge and fall to the ground.  Spillage is wasteful, costly, unsafe, and time consuming to cleanup.  He wondered if Exair could help him with his application.
Exair recommended the model 110248PKI Super Air Knife.  This model included a 48” (122cm) Super Air Knife, a filter, a regulator, a shim set, and a plumbing kit.  The filter would capture any excess water and contamination from the compressed air line that you would not want on the belt or in the cement mix.  The regulator and shim set would be used to control the amount of force required to remove the cement mix without creating a dust cloud.  The plumbing kit provides all of the necessary fittings and hose to prevent pressure drops and keep our customers from hunting down all the right fittings.
Super Air Knife
The Super Air Knife would be placed underneath the conveyor on the return side after the mix was dumped. It should be mounted about 6” (15 cm) away from the belt and at a 45 degree angle blowing back toward the end of the conveyor.  The force of the air would dislodge any excess mix and push it back to the opening of the mixer. As a result, the cement mix was not being wasted on the ground or creating a dust nuisance, but being used to make cement.
