RAV04/2 is an high speed powder filling machine for macrodosing.
The double step system allow to reach a rate of 80 pcs./min.
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 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 Ų 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 heads with auger tool, assembled on a column; up-down movement of whole device with the possibility of rotation for cleaning operations.
Inox steel hoppers with Ų140 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 80 bottles/min.




LOGIC CONTROLS

Logic controls based on PLC Siemens S7 CPU 313C with special modules for axis control, net weight system and quick counters.
Operational Panel Touch Screen Siemens TP270, 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 (stand by).
Minimum load of caps (stand by).
Bottle presence in filling point (no dosing).
Powder level in main funnel (calling product – stop after xx seconds).


NET WEIGHT SYSTEM

N.4 load cells with capactiy of 400gr. and accuracy of 4000 steps for the whole range.
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.
