Product Briefing Outline: Bystronic glass has introduced sorting systems for buffer operation or used as direct connection to a production line for thin-film solar modules. Thin-film producers obtain modular configurable solutions designed for front-end operations for decoupling the different production processes from each other as well as at the back-end for sorting the ready-made modules prior to packaging.
Problem: In order to sort ready-made photovoltaic modules according to quality, performance classes, physical sizes or other features, a sorting operation is required
Solution: Depending on size and composition, the substrates are stored either vertically, at an angle of 6°, or horizontally. Loading and unloading is carried out by means of conveyors, sorting carriages or robots. The fixed storage systems or cartridges have more than 120 positions, which can be managed in a high-bay warehouse. In order to sort ready-made photovoltaic modules according to quality, performance classes, physical sizes, or other features, a sorting operation is required: After leaving production in the sequence of manufacture, the modules are temporarily stored and then removed at the appropriate time according to the sorting criteria. It is possible to integrate a number of inspection processes in advance–i.e., at the end of the production process and prior to storage and/or sorting. The sorted modules subsequently arrive at the automatic packing station.
Applications: The buffer and storage system is suitable for the storage of both substrates as well as ready-made modules with back rails and junction box — for all conventional glass sizes up to 2.20 x 2.60 meters.
Platform: The buffer and storage system as well as the sorting system are characterised by solid design, high positioning accuracy and gentle handling of substrates and/or modules. The systems are also equipped with their own control system for seamless object tracking, including interfaces to the different processes and the MES (manufacturing execution system).
Availability: February 2010 onwards.
