INFEED FINGER SYSTEM

The elliptic finger movement lets bring the bottles from the loading table to the baskets automatically, without using other pushing members.
Safety devices protect the fingers during their movements.
These fingers are made of high density plastic profiles which assure a noiseless working operation and gentle treatment of the bottle.

WORM INFEED SYSTEM

Whenever special bottles (rectangular, square, oval, etc.) are handled, it is not possible to put them on an accumulation table, consequently a worm infeed system is required.
The bottles are spaced by an infeed scroll and fed to the inload slides through a pushing device which is lined with polyethylene.
Moreover a bar will introduce the bottles into the baskets.

CAMS OUTFEED SYSTEM

The opening of the sliding block transfers the bottles from the baskets and places them on to the cams that, with their rotating movement, take the bottles along the slide conveyors to the discharge conveyor.

The slides and unloading cams are made of high density polyethylene to guarantee a noiseless working operation and longer life cycle. Safety devices protect all the movements.

BOTTLE CELLS & CARRIER

The design of our cells and barrier guarantees the following advantages:

  • Large selection of bottle cell carriers in various widths and lengths.
  • Optimum machine adaptation.
  • Easy replacement of individual cells.
  • Optimized wall thicknesses and cutouts in the carrier side walls which allows lighter weight, smaller surfaces, less media carryover, and less chain guide wear.
  • For the bottler this means energy savings of up to 30%, further reduction in water consumption and less maintenance.

LABEL REMOVAL SYSTEM

These bottle washers have a double-step label removal. In the first step, after about 40% of the total soaking time, sub-sprays remove the loose labels and the caustic flux with the floating labels is guided directly to the outload filtering conveyor extending across the machine.
In the second step, at the end of the soaking time, many sprays hit the bottles everywhere and totally remove the labels.

The caustic solution with labels is guided directly toward the revolving filtering conveyor and a rotating brush removes the labels and residuals which are sticking on it. In order to guarantee a good efficiency of this system in the long period, the nozzles are easily extractable to make a perfect internal caustic.

SELF CLEANING NOZZLES

This spraying system consists of rotating shafts, radially drilled on each row of baskets, having a star on one end operated by a strike fixed on the basket carrying beam. This system gives a perfect synchronism and centering between sprays and bottles, even if the main chain would have to become longer during the years.

Moreover the geometrical shape of these sprays lets the water lick flirt one internal side of the bottles, after the bottom of the bottles and then the other internal sides.

The last advantage of the rotary nozzles is that the rotating spraying shaft causes a water flow reversal every 180░, assuring a self-cleaning effect: dismantling and cleaning are unnecessary.

NOISE PREVENTION

The bottle washers can be supplied with suitable equipment on the inload and outload area in order to reduce the noise levels and to provide job safety for the operators.
This equipment does not interfere with the normal operation.

HEAT INSULATION

With temperatures ranging from 60░C to 80░C, a proper insulation greatly reduces the energy consumptions.
All the machine models can be equipped with optional total or partial heat insulation which is made with panels of polyurethan (high thickness) relined with stainless steel plates.

SOAKING BATH RECOVERY

In order to increase the life-cycle of the soaking bath, Bardi is able to supply 2 different systems of soaking bath recovery:

  • SEDIMENTATION TANK: the bath is sent into a sedimentation tank in which the filtration is carried out through 2 different phase: a non-stop filtration on all the mass of water, at medium pressure, followed by an high pressure discontinuous filtration of the mud gathered in the sedimentation cone.
  • VIBRATING SCREEN: the solution is sent into a solid separator in which the solid solution is filtered by a means of a network of 50 meshes that block every particles of glass and paper.
