Automatic classifiers are compact systems made up of transversely movable vertical frames. This allows large quantities of glass to be stored in very small spaces and can be integrated with automatic loading systems. The spacing between two frames is performed electro-mechanically to create one or more aisles for access to the desired type of glass sheet.
In order to minimise the space occupied, frames are normally stacked one against the other. However, when access to a particular frame is required for pick up, a mobile device which slides underneath the frames moves a specific portion of the warehouse and creates the necessary access aisle between two specific frames. It can be separated in a single movement without having to close and re-open the classifier. This benefits cycle time and minimises machine movements. The sheets can be picked up manually or automatically by automatic glass loading systems such as overhead cranes or selective loaders.
The high degree of modularity allows the warehouse to be designed according to specific needs, with the option of choosing not just the number of frames, but also their loading depth, thus differentiating between the various frames. In addition, “Plus” series frames can be loaded with one row of jumbo glass packs or two rows of half glass packs side by side.
Automation is managed using the latest "PC based" control technology which combines the flexibility and performance of PCs with the robustness and stability of PLCs and allows the classifier to be fully integrated with the loading system with which it continuously exchanges information and loading and unloading lists; this guarantees operation in complete safety and reliability. It is controlled and managed by an independent control panel.
