(2) 1996 Sidel SBO 6/10 two-step stretch blow molding machines (no photos available yet) GENERAL INFORMATION The SBO 6/10 has 6 molds and 10 heating modules. It can produce up to 7200 bottles per Hour in a wide range of bottle sizes and styles from 0.25 to 3 liters. Sidel 2-step ^PET stretch-blow molders require previously manufactured preforms be supplied to the machine. Separating the bottle manufacturing and preform manufacturing processes allow production to be optimized, provide greater flexibility of operation and use, and provide higher production output rates and yield. MAXIMUM PREFORM DIMENSIONS Neck height 9 - 41 mm (measured from bottom of support ring) Minimum inside diameter of neck 19 mm Maximum outside diameter of neck 34 mm Preform support ring diameter 29 - 51 mm Maximum preform length 210 mm MAXIMUM BOTTLE DIMENSIONS Maximum bottle diameter 130 mm Maximum bottle height 380 mm Bottle capacity 0.25 - 3 liters AVERAGE PREFORM WEIGHTS (non carbonated and carbonated liquids) 0.25 liter bottle 14-20 grams 0.50 liter bottle 20-33 grams 1.00 liter bottle 26-40 grams 1.50 liter bottle 35-51 grams 2.00 liter bottle 44-58 grams 3.00 liter bottle 68-84 grams SBO 6/10 SPECIFICATIONS: BLOW WHEEL Height 3.5 meters Number of molds 6 Closing force 10 tons Item height (under neck) at outfeed 1.4 meters approximately Machine DC drive motor power 4 KW HEAT CONDITIONING Height 2 meters Number of oven heating units 10 Number of heating zones per unit 8 Maximum power 170 KW ELECTRICAL USAGE Maximum supplied power 200 KW Average consumption 100-150 KW/hr (varies per bottle being produced) COMPRESSED AIR Supplied power from 7-35 bar Pressure 7 bar Flow rate 50-100 Nm3/hr (varies per bottle being produced) Blow pressure - champagne base up to 25 bar Blow flow rate - champagne base 110-550 Nm3/hr Blow pressure - petaloid base up to 35 bar Blow flow rate - petaloid base 155-770 Nm3/hr CHILLED WATER Temperature 10-12 degrees Centigrade Pressure 5-6 bar Flow rate up to 6 cubic meters/hour Kcal to be removed up to 16,000 Kcal/hour WEIGHT Blow wheel with molds 8 tons Heat conditioning unit 2.2 tons Preform feeder 0.65 tons Electrical cabinet 0.85 tons OVERALL DIMENSIONS (including open gate access etc) Length not including preform feeder 4.0 meters (157 inches) Length including preform feeder 9.3 meters (336 inches) Width 6.4 meters (252 inches) DESCRIPTION AND OPERATION OF SIDEL SBO 6/10 STRETCH BLOW MOLDERS PREFORM FEEDER The preforms are held under the support ring by two rails before being lowered by gravity to the feeder plate. PREFORM HEAT CONDITONING The preforms are transferred neck up to the heat conditioning device. This unit continuously insures the preforms are inverted before passing, neck down, in front of the heating units and then inverts them again. During the heating phase, the preforms are rotated and their necks protected from the heat in order to optimize the distribution of heat without deforming the neck. Heating is insured by 10 heat modules. Each unit can accommodate up to 8 infrared lamps stacked horizontally whose ends are air cooled. The heating power of 8 zones, corresponding to the 8 rows of lamps, can be controlled in order to optimize the heat profile. These zones are regulated on all SBO Models. After heating, a control by infra-red camera of preform temperature enables regulation of the zones under control, thus insuring maintenance of the required temperature. PREFORM TRANSFER At the outfeed of the heat conditioning unit the preforms are transferred to the blow wheel by means of a transfer wheel. BOTTLE STRETCH-BLOW The blow wheel comprises of 6 molds of the pin type locking system whose opening and closing are cam actuated. Each mold, cooled by inner circulation of chilled water, is fitted in a mold-holding unit with integral mechanical locking. This system allows quick change of the molds. The blow nozzle is then inserted into the neck of the preform, thus guiding the stretching rod, which insures the preform's axial orientation. The blow which insures side orientation takes place in two stages: medium pressure pre blowing and high pressure blowing thus enabling optimum distribution of bottle wall thickness. The blow nozzle insures perfect seal whatever the blowing pressure. The blow pressure control is integrated into the machine. BOTTLE DISCHARGE The bottles are discharged from the blow wheel by an outfeed wheel which transfers the bottles on a star wheel which pushes the bottles onto the machine outfeed. TECHNICAL ADVANTAGES OF SIDEL SBO STRETCH BLOW MOLDERS MACHINE RELIABILITY Robustness and long lasting service components. Transfer and mold open/close motions are controlled by rotary kinematics and fixed cam paths. PROCESS RELIABILITY Constant quality of bottle production based on the precision and repetition of stretch motions, and automatic adjustment of camera controlled heating zones. PRODUCTIVITY High productivity based on synchronization of all cam actuated motions and reduced dead times. INTERCHANGEABLE MOLD SETS Molds can be designed to fit the complete line of Sidel SBO stretch blow molders. SIMPLICITY A single motor with simple motions actuated by timing belts and gears. VERSATILITY Cabinet design enables easy access and fast interchange of molds and customization parts. Settings for heating, output rate, stretching, pre-blowing, and blowing can be quickly and independently changed. The process can be adapted to all types of preforms. AUTOMATIC OPERATION The main functions of startup and operation are combined on the machine integrated control panel. The role of the operator mainly consists of checking preform loading and output bottle quality. BOTTLE WEIGHT REDUCTION Optimization of material distribution based on precision of heat conditioning and stretch motions. STAFF SAFETY Machine startup can only proceed with the doors closed - opening them during machine operation triggers an immediate shutdown of the machine. Noise levels are less than 85dB. MACHINE SAFETY Various safety systems avoid mechanical damage to the machine. Preventative safety systems, such as the ejection of sub-standard preforms before heat conditioning, ejection of unblown preforms and substandard blown preforms, etc. High speed shutdown of machine due to prevent abnormal stress levels etc.
