Hands On Hot Melt Machinery vs. Remote Access Equipment

The hot melt industry has been changing over the years and most recently has made a push for remote access machinery, or even Bluetooth enabled equipment. At Universal Systems, we believe in the old school “hands on” approach to high speed packaging. Having a human component to troubleshoot and catch issues before they even start, in our opinion, is the only way to effectively manage your manufacturing systems. However, some of our competitors are moving toward human-less systems, where one person can manage the line from afar. With the equipment telling the person what they need and when they need it. There are pros and cons to each.

Here are the reasons why we feel like the “hands on” approach to line operators is still important.

Experience

Real time on the spot decision making based on experience will always be irreplaceable.

Troubleshooting

If something were to happen on the line, a line operator can real-time troubleshoot and fix the issue faster and more efficiently than a computer.

Eyes on the Problem

Putting your eyes on the actual problem helps you to better understand what the issue is and how to fix it. Reading an error code or getting an alert that you then must spend time researching is not always the best solution. If you can see why the line is down, then you have a better chance of getting it fixed and back up and running quickly.

Makeshift Fixes

Not that we are a proponent of makeshift fixes, sometimes it is necessary. With someone on the line, they can quickly switch out a filter or unclog a nozzle without there being much downtime. If you are working remotely, you would then have to call down to someone on the floor to make the switch, which could take more time than your operation can afford.

Overall, while computers and technology can be helpful and advance the industry, nothing can effectively replace a valuable line operator with experience and the ability to think on their feet. The same goes for technical support. It is invaluable to be able to work with a company who can offer you real-time technical support. At Universal Systems, you can always speak to someone who can help. We don’t send you through teleprompts or force you to send an email that may or may not get answered in a timely manner. We pride ourselves in our response times and helping our customers who are on the floor and putting in the work to get their equipment running at maximum capacity.

Why Glue is Better Than Tape to Seal Boxes

Having been in business for over 40 years, here at Universal Systems we are a little biased regarding why glue is better than tape, however there are some key differences that all packaging facilities should take into consideration before buying a case sealing system.

Are you looking for a case sealing system that is durable, reliable, easy to maintain and affordable long term? If so, then you should definitely look into hot melt systems. Universal Systems’ ProBilt melters are stainless steel and come with a 10-year heater warranty. We offer full time customer service and can easily walk you through setup and maintenance. Tape sealers can be more difficult to set up and run for high-speed packaging. Tape is also not as forgiving as glue, and more expensive per box. It can get jammed more easily and needs to be replaced more often, increasing your long-term budget.

If you are running a high-speed packaging line, sealing a lot of boxes, then you should probably use hot glue versus tape. Tape machines have a much slower run time than hot glue application systems. While it does take time for the glue to melt and allow it to set, once hot glue is applied, it will be on there forever. Glue is also more durable through all different types of weather conditions. Tape tends to unstick in heat and in cold. The strength of adhesion you get with hot glue is much stronger than tape. So, if you are sealing boxes that are heavy, such as bottles, then hot glue is the way to go.

The application process is also very different with hot glue than tape. With hot glue, you have the versatility to use it for several different types of applications including larger or smaller boxes, filters, non-wovens, etc. Additionally, through nozzle size and air pressure, you can regulate how much glue you apply to each box. With tape, it is a set feature that you cannot change.

For all of those reasons and more, if you are evaluating case sealers make sure you take a look at every aspect of your business now and in the future. If you are running a large packaging facility and need versatility and longevity, go with hot glue. If you are smaller and have a set box sealing system in place that will not change much over time, go with tape.

If you have any other questions about hot glue case sealing systems, please call (561) 272-5442 or email sales@ussefl.com.

How Dirty Air Impacts Your Pneumatic Systems

Pneumatic hot melt systems are run by air in both the pump and the applicator guns. One of the most important ways to ensure the longest run time out of any pneumatic system is to make sure that the air is clean and dry. That can be easier said than done. Most all packaging facilities have oil, water, or debris in their air. That is just the way it is. Some factories will install air cleaning systems and then add lubricators to lines to ensure that other equipment that requires oil runs smoothly. But even with the most expensive and elaborate air filtration system, there will always be some type of substance that gets by and can lead to issues in the pneumatic pumps of hot melt units. The simplest solution is to install an oil removal filter regulator to the air line running to the pump.

Oily air is our most commonly found issue inside facilities that have pumps stop up. The reason is because the shifters are manufactured with very specific tolerance clearance between the shifter spool and sleeve. This design is a necessity in order to get the pump to shift. Too much clearance and the air will just blow by the spool, never building up enough air pressure to pump. Too little clearance and the shifter will jam. That being said, if you have oily air or dirty air being run through the shifter, over time, that will cause a film to build up inside the shifter and cause a jam. Depending on the amount of oil or dirt in your air, and the number of hours the systems is run for, will determine how long this will take to happen. However, if you feel like your facility air is questionable, we suggest that you use the oil-removal filter regulator to prevent any shifter stop ups.

Another pump issue that can be caused by dirty or oily air is that it can get into the air motor and damage the rulon seals. The seals need to be tight to snuggly move up and down the air motor and if they get damaged by oil or dirt, that can lead to your pump not efficiently pumping. These seals can be replaced over time and should be checked every 2,000 hours.

Universal Systems offers pump rebuild kits for the seals, as well as sells the shifter valves in case you ever run into a pump issue caused by dirty, oily air. For more information on our pump rebuilding services, or for any technical support you might need, please call (561) 272-5542 or email sales@ussefl.com.

How Melter Sustainability Lowers the Impact on Your Budget

Budgeting is nothing new, it is one of the toughest parts of business. When you are running a packaging plant and need equipment, but the budget does not allow for it, what happens then? There is an answer to that dilemma…buy reliable melters and do preventative maintenance from the start.

Reliability is what we focus on at Universal Systems. We know that being up and running is the most important part of high-speed packaging. Not only do we offer full time customer service and an unparalleled heater warranty, our melters and components are easy to install, easy to operate and the most affordable on the market. All of our ProBilt melters come with a 4-hose max capacity and 10 year heater warranty. They also all run the same pump and same AccuScan Control Panel, no matter what size tank capacity, allowing you to stock less overall inventory since there is such versatility. This key feature helps you in lowering your overall budget spending.

When calculating budget, you also need to take into consideration personnel and training of personnel. The Universal Systems ProBilt melters are easy to install and operate, proud of the fact that we are plug and play. With just the press of a button, you can set the temperature on your tank and all your hoses and guns. With our seamless set back feature, you can leave the tank heated to 165 degrees if you are not using it for a shift, then heat back to regular set temperature within minutes to run at full capacity again.

Another key fact in lowering your overall spend is preventative maintenance. At Universal Systems, we really push our customers to maintain their equipment and keep it clean and filtered. Be as good to your equipment as you want it to be to you. Spending only hundreds of dollars monthly on preventative maintenance items such as filters and cleaning kits will save you thousands of dollars per year trying to fix what you could have prevented. We put together a suggested preventative maintenance schedule. For more information call one of our sales reps today at (561) 272-5442 or email sales@ussefl.com.

Mini Modules and Gun Applicators

Several Years ago, Nordson® introduced the MBII gun applicators and modules. Initially, the small module and applicator manifold was made for packaging lines that were designed with little room for glue application. Then, they started offering them in a low-profile design for case sealers. Over time, Nordson® started using MBII guns and modules as standard equipment on all of their packaging line set ups. Why? Even though it is not clear the need for the MBII in most standard application setups that have room for an H200, the price surely made it a much more profitable product in Nordson’s® arsenal. The MBII is more than double the price of a standard H200 module and gun applicator.

The key question to ask is, when do you need to use a MBII applicator versus a standard H200 applicator? Like we mentioned earlier, a MBII applicator is essential on packaging lines that have about half the space to fit an applicator than typical lines. Not only is the manifold about half the length and height of a standard H200 gun, the modules measure a mere 1” x 2” in size. Additionally, MBII applicators have the filter built into the manifold. This is a space saver because it eliminates the need for the in-line filter assembly off of the back of a standard gun into a hose. This allows for the MBII gun to attach directly to the hose and still be able to filter out all of the char and debris travelling through the hose and into the manifold. MBII guns also are air open, air close systems, so you can only run them if you have your line set up with two air lines running to the gun. MBII modules do still fit all of the standard H200 nozzle tips. So, even though you cannot use your standard H200 module on the MBII manifold, you can use all of your current stock nozzles.

If your new packaging line comes in with a MBII system installed, our recommendation is to measure the space where the applicator is mounted. If you have room for a standard H200 applicator and in-line filter assembly, you can always switch to a standard H200 set up. The only thing you will need to change out is the gun, filter assembly and solenoid. This will save you thousands of dollars in the future…but only if it fits.

How to Determine Heated Hose Length for Your Packaging Line

One of the most important things to consider when setting up your packaging line is the best length hose that you should use for both the top and bottom applications. While most maintenance managers think the longer the better, that is not always the case. Heated hoses should be treated with care to ensure durability and run time. At Universal Systems SE we recommend that you map out where the tank will be situated and then where the guns will be mounted. When setting up the top applicator line, make sure to account for hose mounting brackets and try not to make too many turns. The hose line should run as direct as possible to the applicators. We recommend that the hose mounts be hanging mounts for top applications. This will cause no kinks or damage to the exterior hose casing and ensure the long run life of the hose.

When setting up the bottom line, the hose should be mounted down the side of the packaging machine itself. You can use hanging mounts here as well. Make sure not to lay or run the hose on the floor. Also, do not coil the hose under the tank. If you have any leftover hose that you need to coil…your hose is too long. Running the hose on the ground and coiling the heated hose could cause a plethora of issues such as power shortages, heating issues or tripping hazards, all dangerous to your employees. Make sure to keep the area around the tank and hoses clean and hazard free.

The most common hose lengths sold are 6’, 8’, 10’ and 12’. However, Universal Systems does manufacture 2’, 4’, 16’, 20’ and 24’ hoses that we stock. Our biggest piece of advice is to take your time measuring and setting up the mounting brackets. This will ensure that your hoses will last longer and your packaging line will be as efficient as possible.

Help When You Need It

In the post-pandemic age of industry, every company is finding themselves in need of more help. Whether it is qualified technicians with experience in the field, or technical support and customer service from their vendors. A lot of large companies, like Nordson®, have gotten rid of their technical support and customer service representatives, replacing them with automated systems or remote sales reps that do not have a detailed knowledge of each customers purchase history or equipment needs. That is making it difficult for CPGs to troubleshoot issues or for new maintenance managers to know what to order.

Many line operators of hot melt machines are new to the industry, since companies saw their long-term employees retire during the pandemic. At Universal Systems, we not only stayed open and kept all of our employees during the pandemic, we have kept detailed reports of our customers purchase history, as well as a cross reference list of our products to Nordson®. We are always here to take any technical calls or offer Nordson® replacement parts when you need them. With the “supply chain shortage” impacting all Americans, we made sure to back our bets here at USSE. We have ramped up our inventory by double its normal size to ensure that you can get products when you need them and not be held hostage to overseas competitor parts. We make everything in the USA and use all US suppliers. We stand behind our products and feel certain that we would be able to help you with any issue that may arise with your hot melt equipment.

For any technical support please email tech@ussefl.com or call 561-272-5442.

Lowering Downtime on Your Packaging Line

As CPGs continue to change their packaging lines to try and cut costs but stabilize runtime, there are a few things to consider when analyzing the cause of machine downtime and how to prevent it.

The below statistics were taken from the Fall 2021 issue of OEM Magazine:

Causes reports by respondents at CPG companies as the most common cause of packaging machine downtime: 26.3% general wear and tear, 21.1% operator error, & 22.1% product changeover.

General wear and tear is pretty self-explanatory. This would depend on how many hours and days per week a facility runs their packaging lines. If they are running 24/7, then the percentage of general replacement parts purchased will be higher than a plant that is only open 8 hours per day, 5 days a week. To lower downtime, each facility should stock at least 1 -3 replacements, at all times, of the following items: Heated Hoses, Glue Applicators, Modules, Nozzles, Tank filters, and In-Line filters. Another way to lower downtime is preventative maintenance. If CPGs were to prioritize preventative maintenance, then their packaging machinery would last longer and lead to less overall downtime. We recommend PM practices that include changing tank and gun filters, as well as maintaining an even level of heated glue in the glue reservoir of the tank. If done on the regular, general wear and tear percentages would go down.

Operator error is also another large concern for CPGs and the cause of most packaging line downtime. That is because Nordson® and other large corporate OEMs are making their melters more technologically advanced.  Unfortunately, this increased technology does not come with increased training. While technology can create less human interaction, if the line operators are not trained on how to work the equipment, it can lead to more errors. Also, several of the new systems need to run on a network in order to work, so if there is any network downtime, that will now impact the packaging machinery and shut down the line. Universal Systems has maintained our simple to use systems and provides YouTube videos on how to work our machines, along with error codes and how to navigate the control board.

The final most common cause of packaging line downtime is product changeover. To lower overall costs, many CPGs use the same machines to package multiple types of items, which requires a changeover of parts. This downtime might be harder to avoid, however if the line operators are well versed in the machinery and understand the usage need of the machine in all areas, this can be lowered.

Remote Buying & Troubleshooting is the New Reality

After the world shut down in 2020, then slowly started to reopen, it became clear that certain job roles no longer needed to be in an office and could work from home. For the packaged goods industry, that impacted purchasing agents. Now, as maintenance managers run the floor and manage the inventory, purchasing agents are at home trying best to communicate the company needs to suppliers. Realizing the potential that purchasing departments might rely on supplier websites, here at Universal Systems, we focused on updating our website and making sure that there are competitor OEM cross reference numbers easily searchable throughout the site. We also have sales reps that can handle almost any product question and return quotes within 24 hours.

Another impact the pandemic has had on the packaging industry is workforce. There might not be as many skilled and experienced engineers on the floor to troubleshoot issues as they arise. As a manufacturer, we have also experienced setbacks with sending technical reps out to facilities to help them troubleshoot. In an effort to virtually help our customers, we provided YouTube videos on how to set up our ProBilt line of tanks, how to program our control boards and how to set temperatures. We also have several very skilled engineers in house that can walk customers through any issue they may be experiencing. We’ve found ourselves utilizing technology more and more for troubleshooting. Since less techs are allowed in facilities, we have started doing virtual meeting via Facetime or through texting photos. Both have shown to be pretty effective.

Hopefully, one day soon, we get back to workers being allowed to be in the office to physically check inventory and see what they need to order. But until then, we will continue to help our customers as much as we can remotely. If you have any hot melt questions, please feel free to reach out to sales@ussefl.com.
