Dalla 879 alla UltimateSafeChain la stessa affidabilità, ma potenziata

From the 879 to UltimateSafeChain: the same reliability, enhanced

Today’s production lines demand increasingly high standards: higher speeds, lower noise levels, and greater safety.

The historic 879 chain, developed in the late 1980s and established as an industry benchmark, has long proven its strength as a tireless “workhorse” of conveyor lines.

MH Material Handling decided not to settle.

Drawing on nearly forty years of experience and direct, ongoing dialogue with field technicians, USC – UltimateSafeChain was created: an evolution that preserves the robustness of the 879 while integrating with new technologies to meet the real demands of modern industry.

Can something that already works perfectly really be improved?

The strength of the 879 BAT has never been in question: robust, versatile, andlong-lasting, it has earned the trust of operators because it “simply works.”

In particular, tangential drive has proven over time to be the most effective solution for managing LIFO accumulation systems, such as the BAT Buffer, ensuring stability and operational continuity.

However, through extensive field experience and ongoing dialogue with technicians, a key insight emerged: when the foundation is solid, it can be made even safer, quieter, and more efficient.

For this reason, we partnered with Ammeraal Beltech, integrating Safety Finger technology into our new USC chain, a solution already recognized for its strong focus on operator safety.

USC: the reliability you’ve always trusted, even better performance

The new UltimateSafeChain is not a break with the past, but its natural evolution.

It is fully backwards-compatible with existing lines: no system redesign is required—only the chain and sprockets need to be replaced.

The tangible benefits are immediate:

  • Higher operating speeds, increasing productivity without compromising stability.
  • Reduced noise levels, improving operator comfort and supporting compliance with industrial noise regulations.
  • Greater installable length, enabling more flexible and scalable system layouts.
  • Enhanced stability and safety, thanks to the integration of Safety Finger technology, which reduces the risk of accidents and unexpected stoppages.

All of this while preserving what operators already know and value: the reliability of tangential drive, a distinctive feature that continues to deliver top performance in buffering and accumulation systems.

Easy revamping that reduces downtime and hidden costs

One of the most critical aspects of plant modernization is the risk of downtime. Stopping a production line to replace components slows productivity and increases operating costs.

USC was developed with a clear objective: to simplify revamping.

No complex rebuilds, no full replacement projects—just the new chain and the corresponding sprockets are enough to transform an existing system into a more modern, efficient, and safer solution.

This approach fully aligns with the Total Cost of Ownership (TCO) perspective: investing in next-generation components helps reduce hidden costs related to extraordinary maintenance, energy consumption, and unplanned downtime.

Why choose MH Material Handling

At MH Material Handling, every innovation is driven by listening to the real needs of industrial systems.

With USC, we chose to preserve what already works—the robustness and tangential drive of the 879 BAT—and enhance it with new technologies that address today’s requirements: higher speed, greater safety, lower noise, and improved efficiency.

This is not an “off-the-shelf” product, but a solution designed to last over time, reduce risk, and simplify the daily work of those who operate and maintain systems.

That is what sets us apart: transforming conveyors from simple components into true drivers of competitiveness for companies.

If the 879 BAT has been a cornerstone for nearly 40 years, USC – UltimateSafeChain marks the beginning of a new chapter: the same reliability, with higher performance.

Innovations in Palletizer Feeding: current trends and future

In modern packaging lines, palletizer feeding plays a crucial role in ensuring a continuous and smooth production flow. Although the use of low-pressure accumulation conveyors is now well-established, in recent years we have witnessed a real technological evolution that has redefined operational methods in this field.

From Limited Slip Rollers to Modular Chains

In the past, palletizer feeding was mainly managed through friction rollers. Today, the trend has shifted to the use of modular chains with embedded rollers, which, although requiring a higher initial investment, offer numerous advantages.

Modular chains ensure:

  • Simplified maintenance, maintenance operations faster and more efficient. Time reduced by up to 50%.
  • Better product handling, thanks to the denser pitch of the modular chain’s idle rollers compared to friction rollers, allowing for the handling of smaller products and better preservation of their integrity by reducing specific pressure.
  • Long-term efficiency, as the higher initial investment is widely compensated by operational benefits that translate into reduced maintenance costs over the years.

Aerial Lines: An Increasingly Popular Strategy

Another growing trend in feeding lines is the installation of conveyors on high ground, hanging from the ceiling or supported by columns, a solution previously reserved for large productions but now spreading even to small plants.

This is because the advantages of overhead lines include:

  • Space optimization, as they free up the work floor, allowing for better management of areas in the plant.
  • Better ergonomics, as they facilitate operator movement and increase safety within the plant.
  • Integration with automation, as they allow the use of automated transport systems, further optimizing productivity.

This is another interesting point, as the increasing use of AGVs (Automated Guided Vehicles) and AMRs (Autonomous Mobile Robots) for material handling within plants makes it even more advantageous to have free and well-organized spaces.

Feeding Lines with Automatic Format Change: The New Frontier

In recent years, there has also been an increase in demand for feeding lines with automatic format change, a technology that allows switching from one format to another from the control panel. This is pretty much mandatory for aerial lines, where manual changeovers would be extremely time consuming. This solution has become particularly useful for companies that need to manage an increasingly varied range of products or operate in markets where demand changes rapidly.

Automatic format change allows for:

  • Production flexibility: Minimizes downtime during format changes, ensuring continuous production.
  • Reduction of operational costs: Minimizes manual interventions and optimizes the use of human resources.
  • Increased productivity: The ability to quickly change formats allows for maintaining high production volumes, ensuring superior efficiency.

Advanced Solutions from MH Material Handling to Optimize Your Production

At MH Material Handling, we are dedicated to providing tailored solutions to improve the performance of production lines, integrating innovations such as modular chains and overhead lines. Investing in advanced technologies for palletizer feeding is a strategic choice to improve efficiency, reduce maintenance costs, and increase long-term productivity, while maintaining the flexibility needed to respond to the challenges of a constantly changing market.

MH Material Handling is by your side to guide you towards more efficient and versatile production. Contact us to find out how we can optimize your feeding line and ensure its future competitiveness.

Come rendere la tua linea di confezionamento efficiente e anche sostenibile

How to make your packaging line efficient and sustainable?

In recent years, sustainability has become a central theme, not only in mass communication but also in industry. However, when people talk about sustainability, often they only think about the environmental aspect, neglecting other equally important factors, such as economic sustainability.

The packaging sector is also following this trend, increasingly resorting to packaging that uses less plastic or innovative, compostable materials. In parallel, another aspect is becoming increasingly important: production efficiency and waste reduction.

In fact, making production more efficient also means making it more sustainable.

Packaging lines, especially in the food industry, are complex systems consisting of numerous machines working in series or in parallel. Although each individual machine can be highly efficient, the overall efficiency of the line inevitably tends to decrease due to inevitable operational discrepancies or short interruptions.

Conveyors, which act as the circulatory system of these lines, can benefit greatly from the integration of a buffer or accumulation system, which helps to recover lost efficiency.

The role of accumulation systems in the sustainability of lines

Accumulation systems, or buffers, within the line are crucial in keeping the production process smooth. For example, when one machine works intermittently while another requires a constant flow, interruptions in the packaging process can occur. Traditionally, these problems have been solved with simple parking conveyors, but idle stops require more sophisticated solutions to manage production efficiently and without waste.

This is where the BAT Buffer from M.H. Material Handling comes in, an innovative accumulation system that meets these requirements perfectly. At FachPack, we will be presenting an updated version of our BAT Buffer, the result of years of experimentation and valuable feedback from our customers, making it the ideal solution today to ensure smooth, waste-free production.

BAT Buffer: M.H. Material Handling’s solution for efficient and sustainable packaging

The BAT Buffer is a flexible storage system with a configurable structure in anodised aluminium or AISI 304 stainless steel, designed to fit a wide range of products. This spiral device offers up to 150 metres of buffering space using only one motor, a feature that makes it highly efficient in terms of energy and space consumption.

The system is composed of spirals with straight sections varying in length between 2.5 and 6 metres and curves with an average radius of 200 mm, thus minimising the cross section. The technology behind the BAT Buffer allows it to operate with LIFO (Last In, First Out) logic: when downstream machines stop, products are temporarily stored in the buffer. The movement of the chain, controlled by an inverter and a photocell, allows the products to be placed in the buffer without them coming into contact with each other, maintaining zero pressure and preventing damage.

Benefits of the BAT Buffer: efficiency, waste reduction and sustainability

One of the distinguishing features of the BAT Buffer is its ability to manage the flow of products extremely efficiently. When downstream machines come back into operation or in the event of an upstream production stoppage, the buffer can reverse direction and start unloading products. A merging system allows products from the buffer to be mixed with the normal production flow, thus eliminating end-of-shift losses. This process is particularly advantageous for sectors such as bakery products, confectionery, coffee and many others.

Conclusion

In an increasingly sustainability-oriented industrial environment, the BAT Buffer from M.H. Material Handling is an ideal solution for food companies seeking to combine production efficiency and environmental sustainability. With its ability to reduce waste and optimise the production flow, the BAT Buffer not only improves the efficiency of packaging lines, but also contributes to a more sustainable future for the food packaging industry.

M.H. Material Handling will be present at FachPack 2024, Hall 7A, Stand 757, to present the BAT Buffer and other innovative solutions. Don’t miss the opportunity to discover how to improve the sustainability and efficiency of your packaging line!

What worked 10 years ago could be slowing down your packaging line today

A high-quality packaging line can deliver reliable performance for decades, especially when supported by careful engineering and proper maintenance.

The service life of a system represents significant value, but being fully operational does not always mean it can meet today’s production, technological and regulatory requirements.

New packaging materials, sustainability goals, and increasingly demanding industry standards require systems capable of evolving – a particularly important consideration in the food industry, where hygiene, ease of cleaning, and safety are fundamental requirements.

Lane mergers in packaging lines: when they are needed and which one to choose

Converging multiple product lanes into a smaller number of lanes may seem like a simple operation. In reality, the way products are collected, timed and delivered to the downstream machine can have a significant impact on the consistency of the entire process.

This is why designing a lane merger is not simply a matter of considering line speed. First of all, it is necessary to understand how the product behaves: its shape, stability, fragility, ability to run in contact with other products, and the pitch required by the downstream machine are all factors that help define the right solution.

Based on these parameters, M.H. Material Handling designs the merging configuration best suited to the characteristics of the line and the product.

The first criterion is the product: can it withstand accumulation?

Even before speed is considered, the assessment starts with the product and its ability to withstand accumulation.

A product that can tolerate accumulation can withstand the pressure generated by products touching and pushing against one another. Boxes, trays and products stacked in tightly packed formats fall into this category.

A fragile product, or one prone to overlapping, cannot withstand this type of stress, and a pressure-based system could compromise its integrity.

This is why resistance to accumulation is the first factor to be assessed, as it determines whether a pneumatic or dynamic lane merger is required even before line throughput is considered.

There is, however, one useful exception to bear in mind.

Even with a product that can withstand accumulation, the presence of many formats with significantly different widths often makes a dynamic solution preferable. This avoids format changeovers using adjustable or automatically controlled guides and, because the products do not come into contact with one another, eliminates the risk of misalignment.

Pneumatic, DU Series or HP Series: the right technology for each product

A pneumatic lane merger is the simplest and most cost-effective solution, but it is suitable only for products that can tolerate accumulation.

It operates using gates on the infeed lanes, which release the product rows in sequence, and requires two conditions: the products must be able to withstand pressure during accumulation, and the downstream machine must be capable of receiving products in a continuous train without being adversely affected.

The second requirement has a specific technical reason. At the outlet, the products are close together or touching. When this train reaches the downstream machine, the instantaneous speed seen by the machine is therefore twice the average speed. Either the downstream equipment must be able to handle this, or the flow must be normalised using a deceleration conveyor followed by an acceleration conveyor, at the cost of a larger footprint, two additional motors and more complex control logic.

The pneumatic solution is also well suited to a particular application: where the carton itself is the primary package, as is common in the pasta industry, in the section between secondary packaging and the case packer, where the product can be accumulated.

When, on the other hand, the product is delicate or must be handled without contact, dynamic lane mergers are used. M.H. offers two series.

The DU Series merges products by reducing the number of lanes through anti-overlap timing belts operating at controlled differential speeds, one for each infeed lane. Products are handled individually and without contact, making the system suitable for fragile products or products prone to overlapping, at speeds of up to approximately 240 pieces per minute.

The HP Series is the evolution of the DU Series, developed specifically for high-speed flow-wrapping lines and for connections between primary and secondary packaging. In this case, pressure is completely eliminated because the products must never come into contact. Each item is individually timed by means of a multi-belt system with independent brushless drives for every infeed lane, combined with blower-generated vacuum for higher acceleration rates, reaching up to 600 pieces per minute at the outlet. In flow-wrapping applications, precise product timing is essentially mandatory, as it is the only way to prevent products from overlapping.

Outlet pitch: a detail that should not be underestimated

As speed increases, it becomes essential to achieve the most consistent possible product pitch at the outlet of the lane merger, because this determines how the downstream machine receives each item.

A product flow delivered in trains can push the downstream machine beyond its production limits because of the instantaneous speed peaks described above. Individual product timing, on the other hand, controls the distance between packs and transfers them without contact, reducing the risk of jams and overlaps.

The choice always starts with the product

In every case, the starting point is always the product. The first step is to determine whether it can withstand accumulation, then assess its fragility and shape, the required production rate and the number of lanes to be merged, and finally the type of downstream machine, particularly whether it is a flow wrapper positioned between primary and secondary packaging.

The right technology emerges from these answers: a pneumatic lane merger for products that can withstand pressure, the DU Series for products requiring contact-free handling, and the HP Series for high-speed flow-wrapping applications.

At M.H. Material Handling, we manufacture material-handling systems and efficiency solutions for packaging lines in the food industry and related sectors. Over more than forty years of field experience, from food & beverage to pharmaceuticals and packaging, we have developed the expertise required to identify where lane merging can make a real difference and where it is unnecessary. On this basis, we design customised pneumatic and dynamic lane mergers from the DU and HP Series, starting with an analysis of the production line.

If you are planning a new line or a revamping project and lane merging is still an open issue, we can assess it together to identify the most suitable configuration.

Convy VP1

Conveyor: much more than just a connection between two machines

What happens when the connection between the machines in a packaging line is not designed correctly?

The risk is that slowdowns, accumulations, micro-stoppages and disruptions in the flow may occur, affecting the efficiency of the line and, over time, the overall performance of the plant.

This is the idea behind the new video series from ConveyorU, the M.H. Material Handling Academy dedicated to intelligent product handling in packaging lines.

Guiding you through this journey are Convy, the Academy’s mascot, who asks the questions of those who work in production plants every day, and Luca Fontana, CEO of M.H. Material Handling, who answers based on forty years of experience in line design.

In this first episode, they address an apparently simple question: why are conveyors so important?

As the video shows, the value of a conveyor depends on how it is integrated into the line, the required speed, the operating conditions and the specific production requirements.

The required characteristics also vary significantly depending on the industry: a line dedicated to food or pharmaceutical packaging has different priorities compared to an application in logistics, mechanical engineering or the automotive industry.

This is just one of the topics covered by ConveyorU, a journey dedicated to the different aspects of product handling and packaging line efficiency.

Do you want to improve the efficiency of your line?

Every line has different conditions, products and critical issues. To identify areas for improvement, it is therefore necessary to analyse the process as a whole, looking at how the machines interact and how the product is handled.

The M.H. Material Handling team can help you assess your line, identify any critical points and develop a solution based on the actual needs of your plant.

Less Packaging, More Line Problems. The hidden cost of sustainability on your machinery

It happens for different reasons. Sometimes it is a decision made by the purchasing department aimed at reducing costs. Sometimes the end customer requests less plastic. Sometimes it is compliance with new European packaging regulations, such as the PPWR Regulation. Sometimes it is all of these things combined.

Whatever the reason, when the primary film gets thinner, the package becomes lighter and more deformable.

On the conveyor, however, this means less stability.

On the conveyor, just a few microns change everything

A 28-micron film creates a very different pack from a 40-micron one. Lighter and more flexible, it is more affected by any type of contact – whether with product guides or with other packs in accumulation zones. The risk of deformation or overlapping inevitably increases.

Downstream, this results in micro-stops and scrap, and often in complaints from customers receiving damaged products.

The packaging machine continues to run as usual, but the entire section between production and packaging is no longer suitable for the new format. As a result, speeds, chain type, side guides, and contact surfaces all need to be reconsidered, because the entire conveying section must be recalibrated according to the new mechanical properties of the pack.

The buffer that worked yesterday may no longer be suitable today

An accumulation system is designed based on the real parameters of the format, such as weight, rigidity and pack dimensions. When these parameters change – for example, when switching to lighter or more flexible packaging – the behaviour of the product inside the buffer changes accordingly. In a pressure-based system, a less rigid pack therefore risks deformation or damage during accumulation if everything is not correctly set.

The MH Material Handling BAT Buffer operates without pressure on the product and is designed to be flexible and configurable across multiple formats and layouts. This makes it suitable even for lightweight and delicate packs.

However, flexibility does not mean that a single setup works for everything: if the format changes significantly and the buffer is not readjusted, the risk of jams and damage remains.

A useful rule of thumb during the design phase is that a buffer should hold between 2 and 5 minutes of production: the time needed to absorb the typical micro-stops of the line without losing productivity. With lighter formats, however, it is worth recalculating both the effective accumulation capacity and the discharge speed, considering that the downstream machine should be able to run at least 10–20% faster than average to recover the accumulated product.

Downstream of the packaging machine is where the real game is played

When package weight and rigidity change, the requirements of the downstream section of the primary packaging also change. All downstream mechanics – aligners, phases and lane combiners – are suddenly handling a product that is no longer matches the original design assumptions.

The packaging machine keeps running, but the downstream area – the one nobody actively monitors – is where efficiency is lost.

That is why every format change requires a check of the feeding and conveying systems, and it must be done before problems arise.

How to adapt the line without stopping production

The process starts with mapping the characteristics of the new package: weight, dimensions, rigidity and coefficient of friction.

The new format is then tested across every section of the line, not only on the packaging machine, because each section reacts differently and must be checked individually.

The most important step is to involve the conveyor supplier already during the design phase, not once the problem has already become evident.

Working in stages – validating one section at a time before moving on to the next – allows production to remain active while reducing risks.

The format changes. The line cannot stay the same

When a company decides to reduce packaging weight or thickness – whether to cut costs or to meet sustainability requirements – the decision usually starts in the purchasing department. A thinner film is selected, the price is negotiated, and the specification is updated in the system. And then it stops here.

The problem is that no one checks the impact of that change on the packaging line. The process engineer is not involved, at least not immediately. They are called in weeks later, when machine downtime starts to increase, scrap rises, and OEE drops without an obvious cause.

The machine is the same. The product is the same. However, the packaging has changed, and that change affects the entire line: from packaging to accumulation, from conveying to palletizing.

For over 40 years, MH Material Handling has been designing conveying and accumulation systems. We work on layout analysis, buffer configuration, feeding system adaptation, and the integration of new solutions into existing lines, ensuring everything works with today’s format, not yesterday’s.

If you are considering a format change, or if you are already facing issues after a reduction in material thickness, let’s talk before inefficiencies become the norm. A preventive technical discussion costs far less than a stopped line.

Hygienic Design vs Wash Down qual è il sistema più adatto alla tua linea

Hygienic Design vs Wash Down: Which system is right for your line

It’s 6:45 a.m. The line is down for end-of-shift cleaning. The operator directs a high-pressure water jet onto the conveyor, moving the lance from left to right, then shuts off the valve.

On the surface: clean.

In reality: the frame beneath the belt has three enclosed corners where water never reaches. Organic residue builds up there, day after day.

This is not a cleaning issue. It’s a machine design issue. And the difference between a line that passes a hygiene audit and one that barely gets through – every single time – comes down to this.

Washdown: effective on paper, limited in practice

Washdown – high-pressure cleaning with water and detergents – is the most common response to contamination risks in food processing lines.

It’s relatively inexpensive to implement and provides an immediate sense of control.

The problem is that it only works if the machine has been designed to be cleaned. If the frame has enclosed cavities, if chain returns are inaccessible, if joints retain moisture, the water jet doesn’t solve the issue. It just relocates it. The result is increasing consumption of water and chemicals, longer downtime, and a real risk of cross-contamination. Meanwhile, the quality manager signs off on sanitation reports that, in practice, cannot be fully guaranteed.

Hygienic Design eliminates the problem at the source

Hygienic Design, when applied to machinery, is a design approach that starts with a specific question: how can this machine be thoroughly cleaned, under real operating conditions, with the available personnel, in the shortest possible time?

A conveyor built with this logic features open-frame construction, sloped surfaces for effective drainage, tool-less disassembly, food-grade certified chains, and materials resistant to aggressive cleaning agents.

It’s not “washable” because someone claims it is – it’s washable because there are no areas where residue can accumulate.

From an operational standpoint, the impact is significant: sanitation downtime is reduced, water and chemical usage decreases, and contamination risk is minimized. Hygiene audits become a natural outcome of the design – not a recurring uncertainty.

Not every line carries the same risks – that’s why choosing the right approach matters

In practice, the choice between a Hygienic Design approach and a Washdown system depends on where the conveyor is positioned within the line and the type of product it handles.

For unpackaged products – fresh food, meat, dairy, bakery – the contamination risk is extremely high. Here, Hygienic Design is the minimum requirement.

Monolithic belts with no internal fabric, such as the SaniBelt line we design at MH, are specifically developed for this purpose. They have no exposed textile surfaces that can retain residue and can be cleaned in just a few minutes.

When handling packaged products, still within a white area, requirements change. A washdown design can be sufficient, provided stainless steel construction is maintained and flat surfaces and enclosed cavities are avoided. In this case, tool-less belt removal for cleaning is no longer essential. Moving into grey areas, hygiene requirements can be relaxed further, with greater emphasis on robustness and throughput. Depending on the environment, you may still opt for stainless steel frames – for example, where floors are regularly washed with water – or choose anodized aluminum structures where this is not required.

3 practical steps to quickly identify critical points in your line

Before deciding whether to upgrade a single conveyor or redesign an entire section, you need a simple method to identify where the real issues lie.

Here are three key aspects to assess your current situation:

The first step is to map the line by hygiene risk level

Open product, packaged product, and transition zones. For each area, define the conveyor type and the current cleaning regime.

The second step is to inspect critical design points

Enclosed frame corners, cavities beneath chain returns, joints between modules, and moisture-prone areas. If you can’t reach a spot with a cloth, water won’t clean it effectively either.

The third step is to measure actual sanitation time

If it exceeds 20 minutes per conveyor in high-risk areas, you have a design problem. And remember: no stricter cleaning procedure can compensate for a design flaw.

A layout is designed once -but it’s lived with every day

The issue is that most companies address hygiene only when the problem is already visible: a difficult audit, a product recall, or uncontrolled sanitation costs. At that point, the room for action is limited.

At MH Material Handling, we have been designing conveying systems based on these principles for over forty years. From the Saniflex belt for high-risk areas to the BAT system with USC chain for high-speed lines, every solution starts from a real analysis of the customer’s operating conditions – not from a standard catalog. If your sanitation times are too long, if hygiene audits are always uncertain, or if you are designing a new line, get in touch. We can analyze your processes together and identify the most effective solutions to protect product safety and reduce operating costs.
