Flexible Spacer Application
The LiSEC VSA-A is a fully automatic system for applying flexible rolled spacer belts to glass sheets. The patented application technique allows for highly precise and dimensionally stable positioning, as well as low-friction and careful application of the spacer belt within very short cycle times.
The glass transport of the VSA-A consists of a transport wall with support rollers and divided drive zones. An additional directly attached suction beam guarantees safe and precise glass transport. An application head is located on the vertical axis, which is supplied with material via a climate-controlled material box. There is a butylation system on the application head for double-sided application of a butyl cord to the spacer. A sophisticated corner punching device ensures perfect 90° corners and guarantees the leak-tightness of the insulating glass units.
The process begins with the positioning of the sheet by means of a sensor. The sheet height is measured via a sensor in the in-feed section. As soon as the sheet is in position, the application procedure starts. The spacer is transported to the application head via an air-conditioned box, containing the spacer in roll form. There, the protective film on the side is suctioned in and spacer butylation takes place. The spacer is then pressed onto the sheet. Precise punching of the corners guarantees that the corner is optimally formed.
Every insulating glass manufacturer benefits from this system, regardless of the size of the company. The VSA-A is particularly suitable for manufacturers who wish to apply warm-edge spacers automatically, but also for small to medium-sized companies that want to expand their product portfolio and also process flexible spacers in addition to fixed frames - and even for highly automated operations that wish to process all products automatically.
The VSA-A is ideally suited for the production of double, triple and quadruple units. One advantage of the VSA-A is the optional equipment with a two-track application head. This means that manual spacer changes are no longer necessary for asymmetrical unit build-ups. No time is lost changing spacers, which results in a massive cycle time advantage and greatly increases the output of automatically produced insulating glass units. Furthermore, the use of high-quality components keeps operating and maintenance costs to a minimum. The working environment remains clean due to the automatic disposal of corner punch waste and production without downtime is ensured.
Continuous all-around application with perfect corner shape
The free-cutting device clears the area of the corner, enabling an optimal corner finish.
Optimum storage of spacers thanks to climate chamber
The magazine for storing the flexible spacers (SuperSpacer) is monitored by a humidity sensor to ensure perfect processing quality of the spacer at all times.
Small space requirement compared to conventional spacer systems
The LiSEC VSA-A is particularly space-saving compared to conventional spacer systems. Thanks to the compact construction, several spacer materials are available at any time in the air-conditioned warehouse.
