RAV05 is a powder filling and machine for macrodosing. A mechanical system lift each bottle up to effect the dosage directly inside the bottle neck. As option it can be supply a net weight system, checking each sample at 50 pcs/min, with automatic feedback. STRUCTURE AND SAFETY Main structure in aluminum shape, completely covered by inox steel panels. Input and output conveyor belt by one motor: adjustable guides and structure in inox steel. Bottles positioning by high density POLYZENE star wheel. Container size up to Ø 80 mm., H 160 mm. Cab made with aluminium shape and tempered glasses or polycarbonate with mechanichal safety switches. Electrical and logic controls located inside a inox box, side the machine. DOSING UNIT Dosing head with auger tool, assembled on a column; up-down movement of whole device with the possibility of rotation for cleaning operations. Inox steel hopper with Ø140 mm. hole; calling product function and level control by capacitive sensor. Dosage control by 100 pulses/rev. encoder and Siemens quick counter modules. Optional net weight System with automatic feedback, based on high speed load cells and Siemens Siwarex module: 100% controlled up to 50 bottles/min. CAPPING SYSTEM Caps feeding device by vibration cup in inox steel, Ø600 mm., with sound-dampening container. Caps positioning by mechanical or pneumatical device. Closing head for screw or alluminium caps, with adjustable rotation speed and magnetic clutch with torque selection. Two programmable speeds for approaching and closing in up/down movement. LOGIC CONTROLS Logic controls based on PLC Siemens S7 CPU 300 with special modules for axis control, net weight system and quick counters. Operational Panel Touch Screen Siemens TP27, with alarm list, setup function and sensitive areas: statistical report and feedback parameters displayed and printed out on request. Two levels of passwords: user and maintenance. CHECK POINTS Minimum load and maximum load of bottles on conveyor belt (stand by). Minimum load of caps (stand by). Bottle presence in filling point (no dosing / no capping). Cap presence in closing point (stop). Powder level in main funnel (calling product – stop after xx seconds). NET WEIGHT SYSTEM N.2 load cells with capactiy of 400 gr. and accuracy of 4000 steps for the whole range, equal to 0.1 gr. Check weight system by SIEMENS SIVAREX U with digital filters to compensate vibrations: each bottle is checked before filling and after filling and capping. Net weight is calculated. Autotuning feedback system to adjust the weight within the set range: two levels of control (EXAMPLE: from 0% to ±1.5% OK , from 1.5%to 2.5% autotuning of dosing head, more than 2.5% discarding and autotuning of dosing head). Electrical or pneumatical device for discarding out of range bottles. Each function controlled by Touch Screen Panel. Connection to serial printer for printout of report data.
