Description
Functioning
Containers previously filled with solid product by means of the Vibration Filler mod.RPN enter the Vacuum Filler on a conveyor, then they are synchronised by a screw in polyzene and positioned under the vacuum filling valves by an inlet star.
At this stage, by the pneumatic cylinder, the valves lower and position themselves on the container, thus starting the filling procedure according to the phases:
- Vacuum formation.
- Filling with the liquid.
- Vacuum breaking by contact with environment air.
Pre-arrangement for machine feeding by pump or gravity.
The machine is height-adjustable by means of an electromechanical device.
Fast change of the equipment for containers of different diameter and height.
After the container has been vacuum filled it is moved by means of a synchronization tooth (mounted on a plate) to the outlet tangential conveyor, in a delicate manner without abrupt direction changes in order to avoid possible centrifugal forces which would cause the pouring out of the liquid.
After the start-up and first adjustments the machine does not need any operator assistance.
Manufacturing Features
- Basement with supporting plate in carbon steel, structure and total covering with inspection doors in stainless steel, height adjustable supporting feet. The basement includes the driving unit with variable speed motor, transmission devices and the air treatment group with solenoid valves.
- Carrousel for containers hanging support fixed on a fifth wheel.
- Filling carousel mounted on 4 telescopic columns with mechanical device for height adjustment.
- Filling liquid tank in AISI 316 stainless steel.
- Central vacuum manifold.
- Pneumatic cylinders for the valves up and down motion.
- Special filling valves (STV patented) without sliding seals for liquid vacuum filling.
- Cross mounted on bearings and fixed to a column. It supports a ring on which the cams are installed for the vacuum, filling and environment air phases and also the up and down phases of the valves pneumatic cylinders. On this cross are mounted the float for the liquid level control, the vacuum filling valves and tank covers.
- Vacuum pump of liquid ring type in cast iron and rotor in bronze with AISI 316 stainless steel tank. The tank is connected to the machine central manifold and it is equipped with vacuum gauge, level indicator, manhole, washing sphere and discharge valve.
- One screw for one size of container is supplied with the machine.
- Electric control board in stainless steel.
- Manufacturing in AISI 304 stainless steel, except for some parts which are in a different material suitable for their functioning.
- Safety protection system as per CE norms.
- On demand, the machine can be supplied with a tube nest HEAT EXCHANGER in AISI 316 stainless steel.
