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.

The Importance of IN STOCK

Over the last two years, as both manufacturers and consumers, we have learned a lot about the importance of having our most vital items in stock. As we head into the end of 2021 and move into 2022, we have to believe that getting products for both our business and personal lives is going to get increasingly difficult. As large US CPGs have relied more and more on packaging machinery made in China, like Nordson®, they are finding it increasingly difficult to get products. Large corporations have been incentivized for years to move their manufacturing facilities overseas, not only because labor is cheaper, but raw material is cheaper and more readily available. With that, however, the cost of their products has increased due to tariffs and greed, and they are now unable to ship to the US, putting some large CPG facilities in a bad situation.

Here at Universal Systems, we have prided ourselves on being Made in the USA and stocking thousands of items. We still do and will remain sourcing all of our raw material within the USA, as well as keep our most popular products built and on the shelf for our valued customers that need them in order to keep their production and packaging lines up and running. If there are any CPG companies out there that are having issues getting Nordson® products, please reach out to us. We will quote pricing and lead time within 24 hours.

The importance of “in stock” has never been more valuable. We realize that and are dedicated to continue to invest in stocking products so that our customers can get their most vital items in a timely and cost-effective manner.

For pricing on our most popular products, please reach out to sales@ussefl.com.

Top 5 Tips to Hot Melt Machine Maintenance

Packaging lines are complicated pieces of machinery and knowing the ins and outs of each component is important. When you install a new hot melt system onto your packaging line, there are 5 helpful tips to take into consideration to ensure smooth operation and getting the most out of your equipment.

Read and Keep the Manual

The best practice for maintaining your hot melt tank is to read the manual and keep it handy. So many times, maintenance managers will install the tank, but not read the instructions on how to wire it or program it. That can lead to so many issues. In other instances, a tank may be running for some time, but someone hits a button accidentally and changes a setting, then doesn’t know how to change it back. If only they had read the manual or kept it on hand. It sounds like such a common-sense thing, but oftentimes manuals are discarded with the shipping crate. For this reason, we keep a digital manual on our website for anyone to reference.

Replace the Filters

Preventative maintenance is one of the most important tasks to keep your machine running efficiently and reduce down time for your packaging line. When your tank filters are clogged, that is good, it means that they are doing their job and filtering out char. Changing them on a regular basis and spending a small amount on a tank filter will save you thousands in the future.

Monitor Your Hot Melt System

Line operators are tasked with monitoring tanks on a daily basis. It is important to make sure that the pump is pumping smoothly, the solenoid is not lagging and the guns and hoses are heating to temperature and staying there consistently. Even a minor change in any of those tasks can mean that it is time to proactively replace a component, or at least make sure there is a back up on the shelf.

Know Your Options

Knowing your options ties all three previous tips together. If you have read the manual, you will know what your options are when something goes down. If you are doing preventative maintenance, then you know it is not the tank filters. And if you are monitoring your system, you know what components you replace most often and what inventory you have on the shelf. In addition, you should also know what options you have should you need to replace your current system. Is the current technology working for you or do you want to upgrade to an auto-fill system? It is always good to be prepared and know your options.

Listen to Your Workers

Line operators are on the front lines, literally. They watch particular lines and machines on each line all day, every day. They know what parts are running effectively and where the problems may lie. It is important that you listen to them. They might not be the maintenance manager by job title, but they are the most knowledgeable about the equipment they are in charge of and their opinion should be the first requested.

When to Use Micro-Adjust Modules

Hot melt system modules are located on the front of your applicator guns. There are several different types of modules and in most cases, they can be easily replaced on the manifold versus replacing the entire gun assembly. Changing out a module is a more cost-effective way to increase productivity and lower glue costs. Typically, modules need to be replaced when they are having glue dripping issues or major leaking from the nozzle. This is caused by normal wear or char getting stuck in the piston chamber, not allowing it to seat securely.

When replacing a module, you have the option of buying a standard case sealer module or a micro-adjust module. This refers to the module’s adjustment cap on the module body. A standard case sealer module comes pre-set and typically needs no adjustment. This is our most popular style module. A micro-adjust module cap is typically sold on Zero Cavity or ProBead Reduced Cavity modules. These modules have a user-friendly adjustable screw top that changes the pressure of the glue through the nozzle. This allows the operator to dial in a precise glue bead. Typically, zero cavity and ProBead reduced cavity modules have micro-adjustable caps for this reason. For example, they are used on medication boxes or beauty supplies. Another advantage to a zero cavity or ProBead reduced cavity micro-adjust module is the self-cleaning functionality, limiting charring and clogging.

For more information about micro-adjust modules please reach out to a technical sales rep at sales@ussefl.com or call (561) 272-5442.

How to Effectively Clean Your Melter

Keeping your hot melt adhesive system clean may not be on the top of your priority list. However, take a look at your melter now, it is probably bronzed and blackened with old melted glue and char in the glue reservoir. That is what travels through your application system and onto your boxes. That is also what is potentially causing clogging issues and why you are replacing so many nozzles. Even though your melter looks like this now, it is possible to clean it and positively impact the longevity of your system. We recommend that you clean your system at least once every quarter. If you are running 24-hour shifts, 7 days a week, then you might want to schedule cleaning once a month.

Universal Systems SE sells a product called Purge Plus™ that, when used properly, will clean almost any melter. The directions for use are simple:

  • Drain all hot melt from tank reservoir
  • Fill reservoir with Purge Plus™
  • Heat Purge Plus to 350°F – 375°F for approximately 45 minutes
  • Open tank drain valve and remove tank filter assembly
  • Slowly start pump and run Purge Plus™ through the tank manifold and into a meal container until reservoir is empty
  • Stop pump, replace filter assembly and close drain valve
  • Carefully wipe any remaining contaminants from tank reservoir
  • Add new hot melt and recirculate through system
  • Drain one cup from each hose

In addition to cleaning the tank reservoir and heated hot melt hoses, if you are running a ProBilt™ series melter, the exterior is manufactured out of 316 grade stainless steel. So, any stainless steel cleaner will shine the exterior of the tank.

For any additional questions about Purge Plus or how to properly clean your tank and hoses, please call a Universal Systems service technician at (561) 272-5442 or email tech@ussefl.com.

How to Change Out a Melter Pump

There are several reasons why a melter’s pump might stop working. The most common reasons are clogging of the ball and seat from foreign matter such as carton dust, and the actuator clogging due to dirty or oily air. No matter what the reason, if your pump stops pumping it needs to be replaced. Obviously, it much more cost effective to change out a pump then to replace the entire unit. However, it is not always easy to switch out a pump, especially if you are new to the line. Below are a few tips to help ease you through the process.

  • Make sure the circuit breaker on the front of the unit is set to OFF once the applicator has reached normal application temperature.
  • Shut OFF the input air to the pump.
  • Set the pump regulator to zero and trigger all guns to relieve system pressure.
  • When removing the old pump, rotate it slightly to break the suction and then pull it straight up and out.
  • When installing the new pump, make sure to torque the screws 15-16 ft-lbs.
  • Connect the pump electrical plug to tank receptacle and turn tank back on.
  • Once the tank board reads that the tank has reached set temperature, wait 15 minutes. This will allow the glue around the pump hydraulics to get to temperature.
  • After waiting 15 minutes, reinstall the air regulator and connect the airline and activate air.

The Importance of Product Support

Universal Systems SE has been manufacturing hot melt equipment since 1981. Starting with hoses and nozzles, then moving into applicators, pumps and tanks. Our first ProBilt tank was launched in 1990. Since then, our melter has only had a couple of generational upgrades. We believe that this is what sets us apart from other hot melt equipment manufacturers in the industry today. We have never believed upgrading our equipment or technology so much that it makes our old tanks in operation obsolete. We have added features and improved upon what we initially launched in 1990, but we have not let technology negatively impact the operational ease of our machines.

USSE believes in the importance of long-term product support and cross compatibility. There are hot melt system manufacturer’s in the industry, like Nordson®, who have discontinued not only production but also product support of their old melters. Both the 2300 series and 3000 series melters, while discontinued by Nordson®, are still in operation in hundreds of packaging facilities across America. Unlike Nordson®, Universal Systems still supports those old melters because we appreciate the fact that many of these melters, similar to the ProBilt melters, continue to run even 20+ years after initial operation. We are one of the only manufacturers in existence to still make and service 2300 & 3000 series pumps.

We also believe in product uniformity across all of our melters. That is why when we designed our melters, we made sure that all of Universal Systems’ ProBilt machines run the same control boards, pumps and tank filters. In most cases, facilities run several ProBilt melters, but only need to stock 1 or 2 of each spare part. That uniformity creates a streamlined and more simplistic inventory process.

As we move deeper into 2021 and our new normal continues to change, think about how the importance of long-term product support and a streamlined inventory process can help keep your packaging lines up and running.

When to Call Your Glue Manufacturer vs. Your Packaging Machinery Technician

With the reopening of many packaging facilities in full swing, here at Universal Systems SE, we are getting a lot of technical calls that pertain to glue and not the packaging machinery itself. Not a lot of technicians realize that some of the problems they are experiencing with their equipment are actually being caused by the glue. By the way, this has always been the case. Since knowledge is power, below are 2 issues that we get a lot of calls about that are glue related and not machine related.

#1 Glue Related Issue – Char

Many line operators and line technicians have experienced char in their hot melt application systems and most of them think that the char is caused by the machine. That is not actually accurate. The hot melt tank will heat the glue, but only to the temperature that is set by the operator. It is very important to understand how recommended temperature ranges effects viscosity which allows the glue to run at its optimal level. Most charring is due to overheating the glue. That char will travel through your application equipment and cause clogs which will require you to replace equipment or its components. However, that will not fix the long-term problem of charring. If the charring is not corrected, when you install the new equipment it will clog again. That is not a machinery issue, that is a glue issue. Our suggestion is to speak with your glue provider and find out all of the specifications on the glue you are using such as ball and ring, optimal temperature and viscosity. That will save you a lot of money in the long run and should reduce any excessive charring.

#2 Glue Related Issue – Coagulation

There is no doubt about it, glue is expensive. In most cases, the glue can be more expensive than the application equipment. The reason is because most facilities use a lot of it. As we all know, the world has been a crazy place this year, and with the re-opening of a lot of packaging plants, comes new, reduced operating budgets. We have heard from a lot of customers that in order to save on costs, they have had to change glue, whether it is moving to a more inexpensive glue, or a system that lays down less glue but with a stronger adhesion. Either way, if you change glue and do not meticulously clean your glue application system, you can have coagulation causing clogs. We recommend cleaning your tank and hoses with Purge Plus or a similar cleaning substance before changing glues.

At Universal Systems SE, we are always happy to help with any issues that you might have. But keep in mind that sometimes, your issue might be something that you need to discuss with your glue manufacturer. In the meantime, please feel free to reach out to us with any questions at tech@ussefl.com.

Safety in Switching Out Glue Equipment

The best way to keep your packaging line up and running as efficiently as possible is to do preventative maintenance. Here at Universal Systems SE, we have advocated for regular packaging line maintenance, including all of your glue melter equipment and components. However, it is not only important to know when to do maintenance, it is also important to know how to do that maintenance. There are more mistakes made in the switching out of glue equipment and components than you may think. Whether you are changing out a filter or switching a pump, there are steps to take in order to ensure a smooth transition, with the least amount of downtime. Here are a few tips on switching some of our ProBilt hot melt equipment products.

Tank Filters

First and foremost, it is important to know the model of your tank. Even though that sounds like standard knowledge, there are many tanks that look similar but have different tank capacities, pump types and filters. Once you know the tank model, you can look up if you need to replace the entire tank filter or if you can replace just the screen. On USSE’s ProBilt tanks, for example, you have the option to change only the tank screen. This allows you to save some money long term, while still maintaining your tank. It is recommended that you make the change while the tank is in setback and to wear Kevlar gloves so that you don’t burn yourself. The tank filter is located on the side of the tank. It can be removed with a flat head screw driver. Once the complete filter assembly is removed, there is a long screw that secures the screen to the assembly. Simply remove that screw, switch the screen, and replace the filter assembly. If you are changing out the tank screen, make sure that you do not damage the filter bung or o-rings when making the switch. Also, be careful, the glue inside the filter is HOT.

In-line Gun Filters

These are the easiest of filters on your glue line to change out. In most cases, the filters can be reordered in packs of 5. Locate where the filter is on the filter assembly body and use a wrench to loosen and remove. Kevlar gloves should be worn, as the outside of the filter will be hot and there will be glue on the filter you are removing. Simply put the new filter in place and tighten.

Modules

Usually modules are switched out because they are dripping or leaking. This is typically caused by either char or end of life of seat and piston. Switching out a module is fairly simple. Before taking off the old module and replacing with the new, make sure that the system is not running. Each replacement module comes with 2 o-rings and 2 screws. Place the o-rings on the back of the module and secure it on the gun applicator with the new screws.

If you are running an H200, zero cavity or reduced cavity module, there are rebuild kits available.

Pumps

Switching out a glue pump is the least common practice on a packaging line. However, this is also simpler than you would think. Most technicians think that in order to change out a pump, you need to turn the tank off and let the glue cool. That is not always the case. If you are running a ProBilt tank and have an experience technician, he can switch out the pump while the system is still on. First, make sure you are wearing Kevlar gloves because the system will be hot. Turn off the air running to the system, this will limit any injuries. Remove the 3 bolts holding in the pump, use needle-nose pliers and do this carefully. Put the old pump on a large piece of cardboard where the glue can drain, cool and harden. Carefully put the new pump in, secure it with the 3 bolts and turn back on the air.

For any other questions about tank maintenance, please contact one of Universal Systems’ experienced technicians at (561) 272-5442 or email tech@ussefl.com
