Float glass production stacking technology

Stacking technology - good stacking means better glass

Flat glass production: Cold End

For the glass line’s stacking process to work well, it relies on a good sorting process. We can develop a smart system for you so that conveying and stacking are a class act. What’s required are the right number of stackers at maximum capacity to deliver a highly accurate and scratch-free result.

Grenzebach offers best-in-class technologies to guarantee precise stacking at the end of the glass lines:

Sheets of glass can be simply removed by hand or by using a fully automatic stacker
for small, mid-size, large and extra-extra-large glass sheets of up to 24 meters or 26 yards
and weighing up to 3 tons or 6613 pounds.

The sheets of glass can be removed from the tin or air side, from several levels – tiers and drops, statically or picked on the fly. Single or dual pick options ensure greater efficiency. The smart combination of two stackers, which can be used singly or as a pair for extra-long sheets, allows fully flexible production.

Perfect material flow through handling equipment

Grenzebach handling equipment

The Grenzebach portfolio has a large variety of handling equipment, ranging from

portal stackers,
swing stackers,
direct stackers,
under-table stackers
and robot technology.

Various combinations of handling equipment and platforms are possible, too. And it’s all adapted to cope with the subsequent material flow.

Integrated production logistics

Intralogistics

Want to interconnect stations on the glass production line, create links from the cold end to the warehouse or from the production line to temporary storage space? As far as we’re concerned, the sky’s the limit. The factory of the future will revolve around automation concepts that learn as they go along. Traditional conveying technology will grow to increasingly embrace modern robotics and automatic guided vehicles (AGVs), which are autonomous and boast a high level of availability. Automatic guided vehicles enable sustainable flexibility of processes. For example, our software also allows route planning of forklifts and AGVs.

Grenzebach increases efficiently by guaranteeing that the right products are in the right place at the right time.

Service

The engineering and commissioning of a new system are the first steps towards a successful glass line. Professional service in daily business is just as important - which is why we are at your side throughout the system’s entire life cycle.

Technology & equipment

Patterned glass

Drawing glass. Rolled glass. Patterned glass. These terms describe glass with a special surface structure. Grenzebach provides hot end as well as cold end technology. We are your partner along the entire production line, from the annealing lehr to the cold end with cutting, stacking and conveyor equipment.

Tin bath

The tin bath is the heart of every float glass production line; it is a decisive quality factor. Consequently, at Grenzebach, it is always tailored to each customer’s requirements. Using process simulation, we are able to extract the ultimate in yield and quality.

Drossbox

In the dross box, the glass floating on the tin is lifted out of it for the first time and transferred to the annealing lehr. The trick is to transfer the glass ribbon from a liquid and full-surface support to a roller conveyor.

Annealing lehr

The annealing process is a decisive factor for quality, productivity, and efficiency. With our innovative systems, you can keep it fully under control: the latest technological control applications monitor your process at all times, prevent production losses and help to minimize downtime.

Utilities and central power supply

For a float glass plant to operate reliably and at peak performance, it needs a steady supply of energy and other media like natural gas, electricity, inert gas, tin and much more.

Conveying technology

Our technology conveys glass gently and precisely – even over distances greater than 100 meters or 110 yards. What’s more, our conveying solutions operate smoothly and have long service lives too.

Cutting technology

Cutting technology lies at the heart of the cold end of a float glass production line. Combined with the breaking system, the cutting heads, force-regulated controls and an intelligent optimization system form a superbly efficient unit.

Metrology

As a glass manufacturer, a stable production process is more important than ever these days. Grenzebach’s inspection and measurement procedures stand for advanced control methods and top product quality.
