Definitions

• TITLE Device for dedusting shutters by ionization
• the present invention relates to the dedusting of objects, and more particularly, to ionization cleaning devices for bottle closures.
• plastic capsules or stoppers as obturators. In general, this is any device intended to ensure the tight closure of a container.
• the shutters circulate via a bottling line, which conventionally comprises a conveyor allowing said shutters to be transferred along the line to bottling machines performing various operations necessary to obtain a finished product, such as for example a filled and stoppered bottle.
• a bottling line which conventionally comprises a conveyor allowing said shutters to be transferred along the line to bottling machines performing various operations necessary to obtain a finished product, such as for example a filled and stoppered bottle.
• Ionization cleaning consists of neutralizing the static charges of the shutters using antistatic equipment capable of neutralizing the surface of the charged shutters by continuously generating positive and negative ions.
• dust any polluting particle that can become encrusted or stick to the shutter.
• Antistatic equipment is available in several types depending on its use. One can for example cite the ionization nozzles often placed in cleaning systems for capsules.
• the aim of the invention is therefore to overcome this drawback and to provide a cleaning system capable of dissociating small dust from the shutters.
• a device for removing dust from shutters capable of circulating in a chute extending along a longitudinal axis, comprising suction means arranged around the chute and capable of sucking up dust. separate from the shutters, and at least one ionization bar extending longitudinally around the chute.
• the chute makes it possible to transfer the shutters from storage means to a bottling machine.
• the obturators are cleaned during their transfer.
• At least one ionizing antistatic bar associated with a blowing bar arranged on one of the longitudinal sides of the chute is used without limitation.
• a plurality of ionizing antistatic bars associated with a plurality of blowing bars and arranged at at least two longitudinal sides of the shutter. gutter.
• two ionizing bars can thus be positioned with two blowing bars at the level of the longitudinal sides facing the chute.
• Antistatic ionization bars work by emitting an electric field composed of positive and negative ions through emitting tips powered by a high voltage generator.
• the supply voltage is between 7 and 8 kV.
• ionization bars also allows the shutters to be exposed for a longer time to ions, which increases the chances of extracting small dust. This makes the device particularly suited to a bottling rate greater than 10,000 bottles per hour.
• the suction means comprise a first nozzle extending longitudinally on one side of the chute, and a second nozzle extending along a transverse axis perpendicular to the longitudinal axis.
• the first suction nozzle allows ionized air laden with dust to be evacuated.
• the second nozzle thus arranged allows the dust located at this level to be sucked up.
• the suction means comprise at least one vacuum switch capable of detecting the vacuum generated by the first nozzle and / or the second nozzle.
• the suction means comprise at least one blow bar extending longitudinally around the chute and comprising a pressure switch capable of detecting a predetermined value of the pressure injected into the chute and a pressure regulator capable of adjusting said pressure.
• the first nozzle is in the form of an oblong hole and the second nozzle is adjustable.
• This shape has the advantage of facilitating the collection of dust-laden air.
• the adjustment of the second nozzle it is more particularly a question of adjusting its distance from the capsules so as to position it as close as possible to the capsules, and this without disturbing their movement in the chute. This improves the efficiency of dust extraction.
• said at least one ionization bar is made of anodized aluminum or stainless steel, and has a length of at least 100 mm.
• the invention relates to a housing comprising a door for access to a removable chute extending along a longitudinal axis, and a device for dusting shutters as defined above.

• the bottling line includes a removable conveyor 4, here a chute.
• the chute 4 is surrounded by a dust removal device 5 shutters capable of cleaning the capsules which circulate between the storage means 2 and the bottling machine 3.
• each capsule is cleaned by said device 5 before it arrives in the bottling machine 3.
• FIG. 2 illustrates an exemplary embodiment of the device for removing dust from shutters 5.
• the dedusting device 5 here comprises two ionization bars 51 and 52 which extend along a longitudinal axis y-y '.
• the two ionization bars 51 and 52 are able to emit an electric field composed of positive and negative ions via emitting tips supplied by a high voltage generator not shown in the figure.
• the capsules are thus exposed to the electric field over the entire length of the ionization bars 51 and 52 to loosen the most dust from the capsules.
• the dust is therefore found floating in the ionized air inside chute 4.
• the dust removal device 5 comprises suction means comprising a first suction nozzle 53 and a second suction nozzle 54.
• the first suction nozzle 53 which extends longitudinally on one of the sides of the chute 4, is able to discharge the ionized air laden with dust.
• the first suction nozzle 53 is advantageously in the form of an oblong hole, which makes it possible to simultaneously suck up a large number of dust of any size.
• the second suction nozzle 55 is adjustable and extends along a transverse x-x axis "perpendicular to the longitudinal y-y axis". It cleans the inside of the capsule.
• the suction means also comprise, in this example, two blow bars which extend longitudinally around the chute 4.
• the two blower bars allow the discharged dust to be lifted off but also to bring the ionized air and the capsules into contact.
• a vacuum switch 55 is placed here on a suction pipe common to the two nozzles 53 and 54.
• an alert is generated if insufficient vacuum is detected at the suction nozzles 53 and 54.
• the dedusting device 5 is included in a housing 6 which is accessed via a door 61.
