News & Innovations

High-performance, intelligent, low-maintenance Coating
Supplier of complete lines for coating technology including upstream and downstream processes, Grenzebach keeps improving equipment efficiency.

Manufacturers of high-tech glass with highest requirements to architectural aes-thetics and energy efficiency want to surprise their customers with innovations and therefore need coating equipment which allows for flexibility in their portfolio. As a supplier of complete system lines, Grenzebach takes this fact into consideration as well as the running optimization of productivity, energy efficiency and availability of systems. From the raw substrate feeding down to the removal of coated glass and towards the unloading: The solution package comes from a single source; and the Coating experts are also involved in the upstream and downstream processes. „Globally leading glass manufacturers appreciate the wide range - when it comes to the supply of new equipment as well as the upgrade of existing production technology. We are partners for difficult questions about the complete value-added chain“, says Dr. Jens Ellrich, Head of Coating Technology at Grenzebach.

New and upgraded features
Visitors will be able to see a chain of detail improvements on the Coating equip-ment from Grenzebach. This helps to achieve a modular shield and drive system and a higher productivity due to lower maintenance time. The focus is on reduction of downtime and permits higher productivity. A whole series of optimizations contribute to this benefit:

- Gas bar segmentation: Adjustable gas bar segmentation ensures an optimum adaptation to the respective requirements. This leads to a better process control and thus increased productivity.

- Process gas management: The inlet of the process gas directly into the area, where it is needed - at the glass surface in the plasma - in combination with process pumps directly on the cathode lids guarantees highest process stability and optimum reproducibility for lowest possible gas cost.

- Gas separating tunnel: The automatic adaptation of the height of the gas separating tunnel allows a constant gas separating factor for different glass thicknesses, improving process stability, allowing the use of shorter coaters.

For special-purpose applications as they are needed in solar industry or special coatings, the heating of the substrates to 225 degrees Celsius is possible, achieving higher variability in the product portfolio.

In the case of glass gaps of 30 millimeters or less, the coating technology now works even more solidly and reliably. This helps to produce longer campaigns and to reduce the maintenance effort and productivity rises.

The Grenzebach coating equipment is optimized to the lowest floor load possible. For the installation we only need minimum floor reinforcements without special requirements to the foundation. Effect: reduced overall costs.

From the foundations to the finesse of equipment configuration: These have an auto-configuring design. The system automatically identifies the equipment control system, the assignment of pumps, cathodes or empty positions; multi-couplings allow automatic connection to the vacuum, water, current and control system connections.

Data on Glass – Glass sheets with digital fingerprint
In the age of digital glass products, gapless Product Traceability is of utmost importance. Let's have a look at a functioning glass facade on a building: The glass sheet came a long way in the value-added chain. At some point it was bent, cut and stacked on the float line; then it was ground, heat-treated, coated, laminated, processed into insulating glass, framed, fixed - and now dwells on the building. "The long travel generated numerous data about the final product – a real abundance of information", says Peter Seidl, Product Manager Glass at Grenzebach.

This product is interesting from several different perspectives, for glass manufacturers, glass processing factories, transporting agencies, planners, facade engineers, and facility managers, just to name a few. Important data includes manufacturer’s designation, production time, glass sheet ID, dimensions, process and treatment parameters and position on the building. All of this makes up the digital finger print of the product. “We offer the glass industry a large spectrum of technologies to add the digital finger print to their product“, says Seidl. Identification numbers, bar codes or QR cods carry this information and can be applied onto the surface or by means of laser engraving.

Detection of complete glass racks with RFID
Pretty new for the glass industry is the RFID technology (radio frequency identifi-cation). With radio frequency many products can be detected at the same time contact-free and without optical contact, such as complete glass racks. This data in turn can be transferred to the Grenzebach Application Server. The process steps and data with the unambiguous glass sheet ID are linked and a product resume is created.
With the RFID tag, a label with integrated memory chip and antenna, data can be read out and reregistered.
The product has relevant data readily available needed by following actors in the value chain.
For example a glass sheet can transfer glass failure data via the RFID tag, such as the failure type, classification, failure position to a cutting table and can optimize to the best possible cut-to-size result.

„These technologies strengthen the trust between the manufacturer, processor and end user of the glass products", explains Grenzebach expert Seidl. Identification of every single product at any time adds to transparency and is a big step in towards Industry 4.0.

Camera system Float Scan Edge-digital by Grenzebach: An inspection system with crystal-clear value added
By means of the camera system Float Scan Edge-digital (FSE-d) Grenzebach launches a new version of the well-proven FSE camera system into the market, which will increase yield in the cold end of the flat glass production. The system supplies fundamentally important information for the optimized cutting to size of the glass ribbon. This system is available as new device as well as add-on kit for equipment already installed. The cutting equipment allows even more accurate adjustment, so that a bigger portion of the available glass ribbon can be used. In the case of schedule preventive maintenance, the maintenance staff gets significant support through new assistance systems. The further development is based on 30 years of experience with the manufacturing of corresponding camera systems. FSE-d can be directly integrated into the digital system by means of the Grenzebach Application Server. The IIoT platform developed in-house and the supplied information are directly useful for product optimization and reporting. FSE-d provides more accurate function of the cutting technology, which is the core of the cold end of the float glass production line, with numerous values adds; higher yield, higher quality, easier processes, further networking and more data safety.
