Abstract:
A device for producing hollow glassware (1), said hollow glassware (1) including stemware and tumblers, said device comprising a manufacturing line for making semifinished products (2) consisting of solid glass blanks; a manufacturing line for forming the hollow glassware from the semifinished products (2) which is separate from the manufacturing line for making the semifinished products (2) and a storage and supply stage (BV) with storage devices for storing the semifinished products produced in the manufacturing line for making the semifinished products and with transport devices for automatically supplying said semifinished products (2) from the storage devices to the manufacturing line for forming the hollow glassware;wherein said manufacturing line for forming the hollow glassware from the semifinished products comprises a blow molding stage (BF, KE), said blow molding stage comprising a blow head (9) with a blow work ring, a blowing unit (10), a blow mold (11) and a bottom lifter (12) and in which plastically deformable glass gobs are shaped to form the desired hollow glassware; a removal stage (BE, KE) for removal of the hollow glassware (1) from the blow molding stage and for delivery to subsequent processes, said removal stage (BE,KE) comprising removal devices (15,17); a preheating stage (VW) with heating devices (4, 4a) for preheating the semifinished products (2) supplied thereto from the storage and supply stage (BV); a semifinished product heating stage (HE) with heating devices (8) for further heating of the semifinished products (2) at least to a temperature close to a blowing temperature; a transport stage (HB) with transport devices (5, 5a, 6, 7) for transporting the semifinished products (2) from the preheating stage (VW) to the semifinished product heating stage (HE); and a transfer stage (ÃœE) with devices for transferring the semifinished products (2) after the further heating in the semifinished product heating stage (HE) into the blow molding stage (BF, KF), where the semifinished products (2) are available as said plastically deformable glass gobs for blow molding to form the hollow glassware.
