Innovative Float Glass Productionfrom Cold End to Warehouse

Large Size Stacker

Since the introduction of floatglass technology to the market,the name of Grenzebach has beeninseparably associated with handlingand processing of flat glass.Whether as a complete line or as a single component, or simple or

or complicated production processes based on our long experi-ence in engineering we offer technology o high standards with the

best results. From lehr to warehouse the line is separated in several

sections which need to be precisely connected to one another.

Float Cutting Technology

Extreme cutting accuracy and high availability are only two

o the many standards that have to be met. The longitudinal

and the cross cutter are equipped with the field-proven

Grenzebach cutter heads with electromagnetic cutting orce

generator. They allow to precisely regulate the required

cutting orce. The speed o the glass ribbon determines the

positioning o the cutter heads and the cutter head controller

enables a smooth lowering o the cutting wheel by jump-cut

unction. The cutting equipment reaches its highest level o

unctionality in combination with the Grenzebach supervisionand optimisation system.

Stacking Technology theperfect device for each glassFor eeding o glass into a production line and or precise

simple manual take-off up to ully automated stacking or

small and middle sizes and or jumbo ormats weighing more

than 1000 kg. Grenzebach swing arm stackers are using

crank gear drives or a controlled, smooth motion at each

end o the stroke. Our tinside /air-side stacker offers the

option to take off glass sheets alternatively rom upside or

rom below and in certain applications, robots create a use

ull alternative or take-off or eeding.

Efficient Technology for Patternedand Wired Glass

With the increasing demandfor solar glass, patternedglass lines experience a kindof Renaissance. Grenzebachmachinery for these glasses offera concept of high operational

safety and efficient production.

Advantage is taken o our know-how gained in many years o

manuacturing float glass technology especially cutting

machinery to secure high quality o this valuable end

product, optimum yield rom t he material and cost-saving

operation, thus contributing largely to our customers

success. The endless glass ribbon flows onto the Grenzebach

line in various widths, thickness and production speeds. Our

cold end equipment will accommodate all conventional

patterns. In the cutting area, horizontal and longitudinal

cutting bridges divide the glass ribbon. An electromagneticsystem determines the cutting strength and proven Grenze-

bach cutting heads guarantee precise cuts. Special produc-

tion steps are also required or processing o wired glass.

When operating machinery with wire inlay it is possible to

integrate a wire-shearing device afer snapping o the cross

cut. Following this operation, trimming and disposal o the

glass edge is effected on a conveyor that can be varied in

width. Afer trimming, the glass panel is conveyed to t he

stacking device and taken off. Grenzebach offers a complete

range o equipment or stacking various glass sizes. Customers

can choose rom a simple manual take-off to ully automated

stacking. Robots are increasingly used, due to their ex treme

flexibility. Stacking can be made on all conventional racks, inboxes and also in end caps. Highly automated devices can

even be equipped with automatic end cap packing.

Equipment to meet everyproduction needGrenzebach Magnetron lines are our response to the markets

increasing demand or coated glass. Usually working off-

line, these lines can process all sizes o glass. Taken rom

temporary glass rack storage, jumbo or mid-sized glass

ormats are ed into the line by s wing-arm stackers or gantry

eeders. Robots are used to handle small glass plates, alter-

natively, sheets o any size can also be loaded manually.

The glass first passes through a washing machine beore

it is transported into a clean room and enters the coater.

Following the coating process, the line has provision or

inspection o thickness and coating quality either automa-

tically or by the operator. Grenzebach also offer systems to

control the entire surace coating and provide cutting andsnapping equipment or partitioning jumbo or LES plates into

small glass sheets.

Sophisticated stackers for adelicate materialO vital importance in maintaining glass quality is its careul

handling. Under no circumstances must glass be touched on

the coated side. With our range o overhead stackers, tin-side

/ air-side stackers and robots Grenzebach stacking techno-

logy satisfies this requirement, also ensuring accurate and

gentle placing and preventing unwanted marks on the glass

surace.

Options for special operationsGrenzebach lines can be adapted to suit special needs. For

example, as a specific option or European glass coating

lines, we offer protective sheet handling where the firstsheet o a glass batch is lef uncoated in order to protect the

remaining sheets. The entire glass pack is sealed off by adhe-

sive tape either on the stacker or off-line.

Flexible Systems for Safety GlassHigh Performance Cutting Lines

Lines that produce architectural glass in very high

volumes demand very sophisticated equipment.

Their exact unctioning greatly influences quality

and usability o the glass and finally also cost

efficiency. Grenzebach cutting lines are well known

or their flexibility in speed and their high cutting

accuracy. In close communication with the customer

the equipment is designed to production needs.Depending upon your requirements, Grenzebach

cutting tables can handle straight cuts, intermittent

cuts and ree-orm cuts. An optical sensor detects

the edge positioning and there is no need to adjust

the plate position on the cutting table. Cut ting

orce and lubricant eed are automatically varied

to momentary cutting speed. The result: clean

edges without flaking and chipping, easy and rapid

separation o cuts and minimum cutting-oil depo-

sits on glass. An industrial PC with Windows based

computer screens and graphic operator screens

has been developed to be user-riendly. The graphic

pictures are true to scale based on a practicalorms catalogue. The quick and easy cut ting plans

generated can be saved. A cutting plan optimisation

is available on request. This recognises and acili-

tates the elimination o deects ensuring minimum

wastage and a high glass yield.

Laminated glass is used as a standard or or many applica-

tions like overhead installations, bullet proo glass, as sound

proo glass and in many other variations. As flexible as its

scope o use are the solutions or its production. According tothe specific requirements. Grenzebach meets these needs by

offering unctional technology or laminating production lines.

Control Technologymade by Grenzebach

Ultrasonic bondingunites metal and glass

Wherever metal meets glass, the connec-

tion has previously been o rather short

duration. However, interaces o this

kind are widely used in practice, such as

in aade elements or brackets or solar

modules. Grenzebach has addressed this

topic and already registered a patent or

ultrasonic welding. This process makes it

possible to achieve a lasting bond between

glass and metal. At present, the techno-

logy or ultrasonic welding is still being

improved and refined; a test machine isalready running. There are many interes-

ting potential applications or this process,

representing new markets or the Grenze-

bach Group once again.

The new vacuuminsulating glass (VIG)

The production o sheets o glass with

significantly improved insulating values

represents a promising uture technology.

The new vacuum insulating glass (VIG) has

heat transmission values that would other-

wise only be possible with triple glazing.

Instead o using a noble gas in bet ween

the panes or insulating purposes as in

the past, VIG has a vacuum between two

panes. This vacuum provides extraordi-

narily good insulation. In addition, the

complete glazed panel is very thin, becausethe vacuum between the two panes o

glass only needs to be about 1 mm thick.

As a result, window glazing o this kind is

perectly suited or renovating old buil-

dings. VIG is a real product or the uture,

but it does need a special manuacturing

process. Grenzebach is conducting inten-

sive research and development here. The

first complete pilot plant or manuactu-

ring vacuum insulating glass is planned or

the near uture.

Grenzebach offers a complete range o machine

controls, always designed to the specific appli-

cations. From PLC control up to complex controls

or robot moves. Operating menus can be recalled

separately or production, quality assurance, main-

tenance and programming. The graphic operation

concept is clearly structured and all stations are

ully linked with each other. It is possible to deter-

mine in advance any unction patterns while illogical

entries are rejected and an explanation is given.Host computer and optimising system under take

overriding tasks such as production planning, admi-

nistration o orders, capacity and quality optimised

production and reporting to an ERP system with up-

and download unction. This means that the Gren-

zebach system can be ully integrated into an exis-

ting ERP concept. Training programmes and teleser-

vice to find ast solutions to problems support the

operating staff. Updates can be uploaded easily.

Grenzebach offers a vast range o control technology

or every level o automation:

Intelligent drive technology

Visualisation and operation

Host and optimisation systems Reporting tools

ERP connection

Teleservice and 24 hour service

Control of the production process at all times, quickreaction and full use of the line capacity the Grenzebachcontrol system meets these requirements at its best.

Laser cutting

The laser cutting process runs

similar to the conventional

cutting process. Its absolute

advantage, however, is the total

lack o micro cracks on the glass

surace. The Grenzebach laser

cutter uses a CO2 laser with

a specific wave length that is

absorbed by the top glass layers

and where it is converted into

heat. A set o special and adjus-

table mirrors deflect and ocusthe laser beam over a specific

length along the score line. This

is done several hundreds o times

within a second and heats up the

glass surace in a controlled way.

The heat is applied in a way that

avoids negative effects to the

glass structure.
