RLF - Recirculation filling system

RLF - Recirculation filling system

ENOBERG’s RLF series is the most versatile filling machine both for glass and PET containers.

It is suitable for filling products such as vinegar, sauces and spirits at medium-high speed.

The innovative recirculation filling system is able to bottle frothy products without affecting production; the excess product is collected in a small external tank, ready to be filled again.

The machine can be configured for hot filling with recirculation system in order to guarantee a constant filling temperature and a return to pasteurizer of the product to be filled.

Complete, versatile and easily serviceable, thanks to the filling valve entirely designed by Enoberg, it guarantees a high precision filling level.

The basic version is equipped with other technologically advanced solutions, such as:

  • 7” HMI (Human Machine Interface) touch screen, supplied by SMITEC;
  • Electrical regulation of the carousels height;
  • Independent movement of the machine axes through ICOS brushless motors with integrated control, in order to guarantee perfect synchronism between the stars and low noise during the functioning;
  • Diagnosis of engine operating conditions through HMI;
  • Quick bottle changeover parts;
  • Rapid and immediate regulation of the filling levels by means of spacers.

ENOBERG’s RLF machine can be fully cleanded thanks to the dummy bottles, to the spray balls contained in the product tanks, to the piping system designed for recovering or recycling, depending on the needs, the washing solution, and to the Automatic cleaning phases (CIP).

Full featured in the basic version, the machine can be customized with different accessories, including:

  • HOT FILL recirculation filling system;
  • Components in contact with the product in AISI 316 steel;
  • Upper covering.

Available in various sizes to cover an extended production range, RLF machines are supplied in filler/capper version and in rinser/filler/capper version.

1INFEED CONVEYOR
The bottles are transported inside the machine through a conveyor belt. This device is an air conveyor in case of PET bottles, or a chain conveyor in case of glass bottles. The bottle flow is regulated using a pneumatically operated gate which, depending on the condition of plant production, enables or blocks the bottles transfer to the first star wheel.


_

2BOTTLE TRANSFER: INLET - RINSER
Bottles coming from the conveyor are transported towards the rinser. This transfer is performed through a rotating star wheel which receives the bottles from the conveyor and transports them towards the rinsing carousel.


_

3RINSER
The bottle coming from the star wheel reaches the rinsing turret where a rubber gripper grabs the bottle neck, and by using a mechanical cam system inverts the bottle (180 degrees) in order to have the bottle lip aligned with its rinsing nozzle. The nozzle is activated, dispensing water or air depending on the filling product and on the customers preference. At the end of the rinsing phase, the bottle is inverted again, coming back to the initial position. The bottle is ready to be moved to the rinsing carousel. Each rinsing turret is equipped with a “no bottle-no spray" system: a sensor placed close to the rinser inlet detects the presence of the bottle. In the event that no bottle is detected, the correspondent turret will not perform any rinsing operation.


_

4BOTTLE TRANSFER: RINSER – FILLER
Bottles coming from the rinser are moved towards the filler. This transfer is performed through a rotating star wheel which collects the bottles from the rinsing turret and transports them towards the filling carousel.


_

5FILLER
The bottle coming from the starwheel reaches the filling turret. The filling technology is based on mechanical opening and closing of the valve. Once the bottle is in position in the filling turret, it is moved towards the filling valve by a pneumatic piston. The valve is opened thanks to the contact and the pressure of the bottle on it. The filling process begins. The product is transfered by gravity from the tank to the bottle. Once the filling phase is completed, the product is recirculated through a suitable circuit and it is collected in an external tank. The product recirculation continues until the closure of the valve. In case of hot filling, there is a continuous product recirculation even if the valve is closed. The valve is mechanically closed: it rises and it comes back to its initial position. The filled bottle is ready to be moved to the capper.


_

6BOTTLE TRANSFER: FILLER – CAPPER
Bottles coming from the filler are moved towards the capper. This transfer is performed through a rotating star wheel which collects the bottles form the filling turret and transports them towards the capping turret.


_

7CAPPER
The bottle coming from the star wheel reaches the capping turret where a star shaped mould allows the bottle centering under the corresponding capping turret. In case of plastic screw caps and plastic pressure caps, the cap coming from caps feeding system is picked up by means of a star wheel called "pick and place". In case of aluminium screw caps, the cap is directly placed onto the bottle opening. Depending on the cap to be applied, it is possible to have rotating capping machines (for plastic screw caps), pressure capping machines (for plastic pressure caps or crown caps), or capping machine having threading heads (for aluminium screw caps). The rinsed, filled and capped bottle is ready to be moved to the outlet conveyor. Each capping turret is equipped with "no bottle-no cap" system: in the event that no bottle is detected under the capping turret, the cap will not be applied.


_

8OUTLET CONVEYOR
The rinsed, filled and capped bottles are moved out of the machine through a chain conveyor. In neck handling version, this conveyor is equipped with automatic height adjustment, which allows the bottle point of support to be tailored to the bottle height.
