Line Vac Makes Golf Ball Testing More Efficient

Recently, we at EXAIR worked with a major player in the golf ball manufacturing world.  As an avid golfer myself, this was an application I could really get a ‘grip’ on and I had the ‘drive’ to propose a solution.

The customer was involved in Research & Development, performing testing on the golf balls through robotic hitting, collection, and attribute measurement. The current set up involved the ball being hit, gravity collection into a PVC tube, and then an operator unhooking the tube, walking it over to and unloading the balls onto a rack, in the same order of hitting. The customer wanted to eliminate the manual task of the tube handling and have the balls delivered directly to the rack area.  The transfer would need to be 15′ vertically, then 15′ horizontally, before dropping down to table level.  A typical rate is only 5 balls per minute. This is a perfect application for the Line Vac, a compressed air operated conveyor.

EXAIR had previously tested golf ball conveyance, as seen in the Line Vac video below (at the 1:53 mark) where golf balls are conveyed 100′, at only 30 PSIG of supply pressure.

To present the best solution to customer, we had 2 dozen golf balls sent to us, and we set-up and simulated the actual conveyance conditions of 15′ vertical and 15′ horizontal travel. We found that the balls could be conveyed at only 20 PSIG of supply pressure, when presented one at a time. When the inlet was flooded with golf balls, simulating a worst case condition, the Line Vac was able to perform the conveyance at 60 PSIG. Operation at 80-100 PSIG is possible providing a operational safety factor.

The customer was impressed with the results and has implemented the model 6984 – 2″ Aluminum Line Vac Kit into the process, making the process more efficient.

Line Vacs- Air Operated Conveyors, and Much More

The EXAIR Line Vac is a tried and true device for conveying parts, materials, and waste – with no moving parts. The list of successfully conveyed materials in the application database is far reaching – including plastic pellets, scrap/trim, chips, pills/tablets, shavings, sawdust and granules.

The Line Vacs can be used for more than conveying large amounts of material from A to B. Recently, one of our automation customers found an application for the Line Vac in the design and manufacture of a custom fill machine.  The machine was commissioned to fill small, plastic cups.  To move the cups from the material staging area to the filler processing area, (10) of the 2″ aluminum Line Vacs were used.  Using a sensor to measure the stack height in each tube, the compressed air is triggered on/off to transfer a group of cups over to the filling area.  See photo below-

Other types of applications that Line Vacs have been used for include pick and place, small space ventilation, fine powder dispersion and light vacuum generation. Another popular use is to integrate into a machining process for waste removal of chips, shavings, and waste removal.

The Line Vacs come in (3) types- Standard, Light Duty and Heavy Duty.  Also, (3) different end connections are available including smooth bore, threaded, and the new sanitary flanged. Depending on the model type, materials of construction may include aluminum, type 303 and 316 stainless steels, and a hardened alloy.  Special high temperature versions are available with temperature ratings up to 900°F (482°C.)

The Case For The Heavy Duty Line Vac

When it comes to conveying bulk materials like pellets, grains, powders, etc., you’ve got plenty of choices:  Mechanical conveyor types, like bucket, auger, and cleated belt conveyors can move product as far as you want, and as quickly as you want…they can be made as long as you want, and as big & fast as you want.  “Fast” as in conveyance rate, that is.  Lead time, including engineering, design, fabrication, and installation, can be months.

Large mechanical conveyors can move tons of material over great distances.

Air operated conveyors are quite popular too, and the dense phase models can move a lot of material a great distance, and quickly.  Like the mechanical types, they have a wide range of economy to scale…and the price tags to prove it.  Medium- and dilute-phase pneumatic conveyors are less complicated in design, which brings us to the heart of today’s blog.

EXAIR Air Operated Conveyors, or Line Vacs, are the simplest of all:  the Line Vac itself used compressed air to generate a “pull/push” to draw material into the suction, and propel it through the discharge.  We have a variety of models to choose from, but our focus today will be the Heavy Duty Line Vac.

EXAIR Heavy Duty Line Vacs are the workhorse of our Air Operated Conveyors product line.  Consider their advantages:

*Made of a proprietary hardened alloy, they offer superior abrasion resistance & durability.  They’re ideal for shot blast and tumbling media…the very stuff that’s MADE to wear metal surfaces down…and it’s no problem for the Heavy Duty Line Vac.

Heavy Duty Line Vac: Hardened Alloy Construction and High Performance

*Heavy Duty also means higher power, which means higher suction heads (up to 2-1/2 times increase) and conveyance rates (up to 11 times greater.)  Oh, and that blasting shot & tumbling media I mentioned?  Standard dilute-phase conveyors may have trouble moving that at all.

*Like our Standard Line Vacs, the Heavy Duty models’ Kits come with a Mounting Bracket for ease of installation, an Automatic Drain Filter Separator to keep the air clean & dry, and a Pressure Regulator so you can ‘dial in’ the performance you need.

Line Vac Kits come with a Mounting Bracket (not shown,) an Automatic Drain Filter Separator (left,) and a Pressure Regulator (right.) Oil Removal Filters (optional; center) are also available if needed.

*Also like our Standard Line Vacs, the Heavy Duty models use common sized conveyance hose (3/4″ to 3″ ID) and are also available with male NPT threads (3/4″ to 3″ as well) if you want to hard pipe them.

Male NPT Threads make permanent and rigid installation into a piping system a breeze.

If you’re looking for a simple, durable, and powerful conveyor system, look no further than the Heavy Duty Line Vac Give me a call if you’d like to discuss your application and/or product selection.

Light Duty Line Vac For Paper Trim Removal

Today I worked with a customer that manufactures a wide variety of material handling equipment including coil unwinders.  The engineer was calling because there was a special project for a coil unwinder that could handle a waste piece of paper trim.  As the metal coil is being unwound for delivery to a metal processing machine, the protective paper is pulled off and was to be collected into a waste receptacle for easy handling and disposal/recycling.  The engineer was hoping to replicate an existing system that used a hybrid blower system, with an extra compressed air nozzle, but in a simpler form.

Coil Unwinder

We proposed the use of the 4″ Light Duty Line Vac– shown below.130400The Light Duty Line Vacs offer an effective way to convey small and light materials a short distance. Like the standard Line Vac, the Light Duty Line Vac converts an ordinary hose or tube into a  conveyor for scrap, trim, and bulk materials.

When the process involves moving low volumes of materials over short distances, the Light Duty Line Vac is a great choice. The simplified (2) piece design offers effective conveying at a lower cost. As an added plus, the compressed air consumption is lowered to levels commensurate with handling the lighter materials, at lower volumes and short distances.  Using a pressure regulator to control the supply air allows for tuning of the transfer rate, and keeps air usage to the minimum amount needed.

The Light Duty Line Vacs are available with inlet/outlet diameters from 3/4″ up to 6″.  With no moving parts, maintenance free operation is assured.

Threaded Line Vacs: Low Cost Conveyor Uses Ordinary Pipe!

EXAIR’s Threaded Line Vac air operated conveyor takes an ordinary pipe and converts it into a powerful conveying system.  A fast, low cost way to convey items such as pellets, scrap trim, bulk solids, chips, paper, small parts, sawdust, granules, and so much more. The Threaded Line Vac attached easily to plumbing pipe couplers, like PVC or iron, making it easy to build a complete system with parts readily available from your local supply house or hardware store.

The Threaded Line Vac are ideally suited for conveying large volumes of materials over long distances.  Like the standard, smooth bore ended Line Vacs, the unit works by ejecting a small amount of compressed air to produce a vacuum suction on the inlet side and a high output flow from the outlet side.  By using a pressure regulator to control the compressed air supply pressure, the rate of conveyance can be controlled to match the application needs, while minimizing the compressed air usage.

3inTrLVbckls_prHR1670x574

Models are available from 3/8 NPT to 3 NPT with materials of construction of aluminum and types 313 and 316 stainless steels (excellent corrosion resistance.)  High temperature versions of the stainless steel Threaded Line Vacs are available as well, for temperatures up to 900°F.

For those processes requiring the highest rates of conveyance over the longest distances and/or the most abrasive of materials, the Heavy Duty Threaded Line Vac is the right choice.  Designed with the most rugged industrial processes and applications in mind, the special hardened alloy construction helps prevent premature wear that could occur with standard aluminum or stainless steel models, under the harshest of conditions.  The performance has been boosted, to be able to convey more material, over longer distances and higher vertical rises.

To select the right model, information regarding these criteria is helpful-

  • Size of parts and bulk density of material being conveyed
  • What size hose, tube, or pipe is desired
  • Target conveyance rate
  • Distance of conveyance, both horizontal and vertical legs
  • Preferred material of construction

For another look, please see the video available that provides more details about the Line Vac family.

When Efficiency And Practicality Collide

Even if you’re a casual reader of our blogs, you already know that EXAIR Application Engineers LOVE to preach efficiency in the use of compressed air…it’s our “bread and butter;” the very nature of our business. This year, we’re celebrating thirty-five years of leading the way in the development of efficient, safe, and quiet compressed air products. Our track record of success as a solutions provider across a diverse range of industrial and commercial applications is well documented in our blogs, as well as Knowledge Base and Case Study Libraries.  We devote considerable resources (engineering, research & development, product testing, etc.) to making certain that EXAIR Intelligent Compressed Air Products cost less to operate, and perform better, than whatever you’re using right now.

Strange as it may seem, though, sometimes our products are EXTREMELY popular in cases where they INCREASE a facility’s consumption of compressed air…by replacing something that DOESN’T use compressed air at all:

*I’ve written before about how our Large Maximum Cold Temperature Vortex Tubes have replaced liquid nitrogen rigs in freeze sealing operations.  Now, a Vortex Tube directs a portion of its air supply to (usually) unusable hot exhaust, in order to generate the usable flow of cold air.  When compared to the costs of liquid nitrogen and the resources involved to get it where it needs to be, though, the cost of the compressed air needed to operate the Vortex Tube is indeed the practical solution.

A 1/4 ton of refrigeration from a product that fits in the palm of your hand, and all you need is a supply or compressed air!

*Line Vacs are probably THE prime example of the value of using compressed air where it wasn’t used before…replacing a “bucket and ladder” operation:

Straight from our Catalog, a perfect example of using valuable compressed air to save even more valuable resources.

*Then there are the situations that just come down to time.  In large spaces, our Super Blast Safety Air Guns can be used to “sweep” the floor in a fraction of the time it takes an operator with a push broom.

Super Blast Safety Air Gun makes short work of large area cleanup.

To make a long story just a little bit longer…if you’re using compressed air, you can use it better with EXAIR’s engineered compressed air products.  And there are plenty of practical applications where you’re not using compressed air right now too.  If you’d like to find out more about either one, give me a call.
