Abstract: A dynamic insulated glass unit (IGU) assembly line scheduler is provided for production control of an IGU assembly line. When calculating the IGU assembly line order and controls, the scheduler evaluates at least i) a changeable set of uniquely identifiable glass lite storage loading locations adjacent a loading station, ii) a changeable set of uniquely identifiable IGU storage locations adjacent a unloading station, iii) a changeable identifiable subset of the set of uniquely identifiable IGU storage locations, and iv) a assembly line change outs to be performed at least in the production of the IGUs for the next in line set of IGUs to be shipped from the IGU assembly line. The scheduler is configured to re-evaluate the IGU assembly order at least with the filling of each next in line set of IGUs to be shipped.

Abstract: A glass production line comprises a style of lean manufacturing to solve many of the inefficiencies in the scheduling of orders through a glass plant. The main goal of the global scheduler of the present invention will be to dynamically adjust the flow of glass through a glass plant for maximum efficiency.

Abstract: An Insulated Glass (IG) line comprises a washer for washing lites; a spacer applicator for selectively attaching spacers to lites downstream of the washer; an assembler for coupling multiple lites with intervening spacer downstream of the spacer applicator; an unloading station for removing finished IGUs from the IG line downstream of the assembler; and a buffer storage unit upsteam of the washer and having i) at least one storage rack defining a plurality of lite storage locations, ii) a storage rack feeding unit configured to place lites into any storage location of each storage rack, and iii) a storage rack unloading unit configured to take lites from any storage location of each storage rack. The Insulated Glass (IG) line further includes a dynamic batch-less direct feed cutter upstream of the buffer storage unit.
