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.)

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.

Coast to Coast and Beyond

Recently, I was working with  a customer looking for a Premium Reversible Drum Vac and wanted it shipped to the Northwest Territories of Canada –  which we could do!  It got me to thinking, what are the farthest US state and territory locations EXAIR has shipped to in the North, South, West and East directions.  I ‘scoured’ the records and came up with these.

Furthest North- We have shipped to Prudhoe Bay, Alaska.  Most recently, believe it or not, we shipped a NEMA 4X Cabinet Cooler to an Oil and Natural Gas Exploration Company.  Goes to show that even the coldest environments still have the need to provide cool, clean, dry air to cool and protect electronics in electrical enclosures.

Furthest South – We have shipped to the US Territory of Puerto Rico, city of Santa Isabel.  An Aerospace company needed a strong, laminar blast of air and utilized a 6″ Stainless Steel Air Knife.  An Air Knife offers a quiet, efficient way to clean, dry or cool parts, webs, or conveyors.

Furthest West- We have shipped to the US Territory of Guam.  The local University ordered a model 1111-4 Super Air Nozzle Cluster, for a good strong blast of air flow for a cleaning operation.  The model 1111-4 delivers 3.2 lbs of force, at just 82 dBA of sound. A safe and efficient nozzle for blowoff operations.

Furthest East- We have shipped to Eastport, Maine.  The customer in Eastport ordered a Line Vac and a section of Conveyance Hose.  The Line Vac is a great tool for conveying large volumes of material over long distances, through a standard hose or tube.  The compact design features large throat diameters for maximum throughput capability.

 

It was interesting to look back and see all the places that EXAIR has shipped.  We have customers from all over the globe. If you are outside the of 50 US States and Canada, we have a dedicated team of International Application Engineers that will work with you to select the best EXAIR product for your process and application, and direct you to your local International Distributor.

Light Duty Line Vac For Part Rejection

Today I worked with a long standing customer that was interested in using the Line Vac technology to provide a method for part rejection.  The parts come out of a bin and travel to the next station for final assembly.  There is an accept/reject analysis system along the way, and it was decided that the Line Vac would offer an easy way to remove the part from the conveyor and transport it to a reject bin.

The parts are very small, with 0.093″ to 0.187″ OD and 0.178″ to 0.335″ lengths.  Part weights were 0.27 grams or less, so a very small and light weight item.  Maximum part processing was estimated at less than 6 parts per minute, so low speed and low transfer rates apply.  The final piece of information was the distance for conveyance, and here it was only a few inches up and then 4′ over to the reject bin.

Based on all the information about the parts, the process and the transfer distance, it was determined that the 3/4″ Light Duty Line Vac would be an ideal choice for the application. The unit is available as part of the  model 132075 Light Duty Line Vac Kit, which includes a Automatic Drain Filter Separator and a Pressure Regulator.  The Pressure Regulator is especially important in this application, as it will allow for pressure adjustment to provide the best performance while keeping the compressed air usage to a minimum.

Light Duty Line Vac Conveys the “Slugs” from a Die Punch Application

At EXAIR, we get asked a lot of interesting questions about what our products can do. One of them that occurs with some frequency is, “Can your Line Vac convey slugs from a stamping operation?” The answer is usually yes as “slugs” (the material punched out of a sheet of stock to create a hole) are well suited in size, shape and weight to be conveyed effectively with the Line Vac product. We are used to this question from folks who are processing various types of metal sheet. The slugs tend to build up within their tooling and basically get in the way, if not even jam up the tooling from time to time. So getting rid of them from the process becomes a necessity that is, many times, not addressed during the tool making process.

Recently, we had another customer with this same kind of problem with foam. They were processing a foam sheet by punching a many holes in it which generated the waste stream you see above. Little pieces of foam about 8 – 10 mm in diameter and about 40 mm long. As you probably have guessed by now, the area that was set up to receive these renderings quickly became loaded full with the foam slugs. The customer needed to find a way to remove the slugs to a remote area so the receiving container could be switched out easily without stopping production. The original container was small, plastic bin about the size of a kitchen garbage can. The new receiving container was a large cardboard box that typically goes by the term Gaylord. The customer needed to set the Gaylord about 3 – 4 meters away from the die punching area. This is where the EXAIR model 130300 (3” Light Duty Line Vac) comes into play. The customer fabricated a chute that was positioned under the area to catch the slugs. The chute transitions to accept the 3” Light Duty Line Vac for connection at the bottom. Then, a 3” hose is connected to the output side of the Light Duty Line Vac so it could blow the slugs over to the Gaylord.

Foam Slugs From Die Stamping Process

The customer chose the Light Duty Line Vac because it uses less air than a comparable size of our Standard Duty units. They didn’t need a tremendous amount of suction power due to the light-weight nature of the slugs. They also wanted a 3” unit to make sure none of the product would get caught anywhere within the conveying stream.

With the new Light Duty Line Vac installed, the operators do not have to spend as much time tending to the emptying of the previous, small containers that had to be used due to their size for fitting into the catch area. For an application where thousands of these slugs are produced in an hour, the productivity gain was significant. The customer didn’t place an exact value on the gain, but are considering this method for other, similar processes they have in the plant.
