In the packaging industry, where every interruption can result in productivity loss, accumulation systems become strategic components to maintain performance and output. One ideal solution is the BAT Buffer by M.H. Material Handling, which we explore below.

The Heart That Keeps Your Line Alive

The BAT Buffer operates using a LIFO (Last In, First Out) logic and is designed to manage micro-stoppages typical in packaging lines. In the event of a downstream stop, the system automatically diverts incoming products to the accumulation buffer, keeping upstream machines running.

The BAT Buffer features a spiral structure that alternates straight and curved sections. This design maximizes available space, offering up to 150 meters of accumulation capacity with a single motor. The straight sections range from 2.5 to 6 meters, while the curves have an average radius of 200 mm, allowing adaptation to complex layouts.

Precision Control, Down to the Millimeter

During loading, products are guided into the buffer with a consistent pitch, regulated via inverter, preventing overlaps or damage—crucial for delicate or pressure-sensitive packaged goods.

Once normal operations resume, the BAT Buffer reverses direction and gradually releases the products back into the production flow. This can be done via an orthogonal transfer unit (to maintain product orientation) or a dynamic combiner for high-speed lines.

The average emptying time, from a full configuration, ranges from 15 to 25 minutes depending on installed capacity and downstream speed.

Recover What You Thought Was Lost

One of the BAT Buffer’s standout features is its ability to recover production lost to micro-stoppages. If downstream machines have an extra 10-20% capacity, the system can completely eliminate these losses by the end of a shift.

Its mechanical structure also enables quick switching between loading and unloading phases without needing full accumulation, helping to regularize the production flow. This operational flexibility makes it ideal for lines subject to frequent format changes or sudden production peaks.

Engineered to Fit, Wherever Needed

The BAT Buffer is ideal in sectors where output sequencing is not critical:

• Bakery and confectionery products
• Coffee and vacuum-packed goods
• Other long shelf-life items

The structure is available in anodized aluminum for standard applications or AISI 304 stainless steel for environments requiring higher hygiene standards, such as cleanrooms. It supports occasional washing without compromising performance.

Its pressure-free design and modular components make it suitable for integration into existing plants, facilitating revamping operations.

See It Live

For those interested in discovering the BAT Buffer’s full potential, M.H. Material Handling will be exhibiting at IPACK-IMA 2025 in Milan from May 27 to 30, Pavilion 7, Booth B21.

For the first time in Italy, the compact infeed/outfeed system of the BAT Buffer—already praised at FachPack 2024—will be presented. Visitors will also get a sneak peek at an exclusive feature designed for those who recognize technical evolution at first glance.
