SFL:FUNCTIONALUNITS Functional units identification功能单元辨认 1. Frame It supports and ensures a perfect coupling of the various functional units. 支撑不同功能单元并确保完美的连接 2. Preforms feeding It has the function of raising, orientating and transferring the preforms from the hopper to the blowing machine, guaranteeing process continuity. 从料斗提升,整理和输送瓶坯到吹瓶机,保证过程的连续性 3. Motorization (single) The unit, operated by a single brushless electrical motor, has the function of moving the synchronously loading wheel, oven wheel and the blowing press unit. 4. Preforms loading The unit has the function of feeding the machine with the preforms needed for production. 5. Ovens 9. Stretching/blowing It includes the following main components: a) A seal unit密封单元 b) A stretching rod unit拉伸杆单元 c) A blowing unit吹制单元 It is connected to the following systems: - Electrical - Electronic (control) - Pneumatic (service + process air) The unit has the function of stretching preform’s material axially through some metal rods and along the radius through a blow, carried out in two successive phases, of high pressure compressed air (10 and 40 bar) in order to give them their final shape (bottle). 9 MACHINE FUNCTIONAL UNITS – STRETCHING/BLOWING TRAINING TRAINING Preforms feeding瓶坯进给 5 Frame机架 Motorization动力系统 Preforms load瓶坯装载 Ovens烘箱 Chain rotation瓶坯旋转输送链 Variable pitch变节距机械手 Transfer device主机械手 Stretch/blowing拉伸吹制 Blowing press吹模运动 Bottles unload瓶子卸载 6 7 8 9 10 11 4 3 2 1 It includes the following main components: a) Machine frame b) Press frame It is connected to the following systems : - Electrical - Electronic (control) - Water system - Pneumatic (service + process air) 1 MACHINE FUNCTIONAL UNITS - FRAME The machine frame consists of a stiff beam structure with seats and supports for housing the following functional units: - Motorization - Preforms loading - Ovens - Chain rotation - Variable pitch The press frame consists of a stiff beam structure, with seats and supports for housing
