Definitions

  • This disclosure relates generally to a container rinsing system and method, and more specifically to air rinsing of containers such as beverage bottles without the use of water or other elements that come into direct contact with the containers.
  • Empty containers such as PET (polyethylene terephthalate) bottles
  • PET polyethylene terephthalate
  • Such containers may become contaminated with foreign material, such as paper, wood dust, or plastic debris during shipping, even when they are stored in boxes or other carrying receptacles.
  • the bottles can also become contaminated as they are being processed prior to filling.
  • contact between the containers and the surfaces of articles, such as conveyors or carriers, used to convey the containers cause the containers to pick up a small amount of net electrostatic charge, thereby rendering the containers capable of attracting fine particles to the containers' internal and external walls.
  • the electrostatic charges on the bottles may cause the bottles to cling to one another, thus causing the bottles to move at an angle. This leads to bottles falling off of the conveying system, particularly when using a belt or rope conveying system.
  • the need to rinse or otherwise clean the containers prior to filling is necessary to ensure that the contents of the beverage within the container are acceptable to the ultimate consumer.
  • Typical dust particles contaminating these containers are extremely small, often measuring less than 10 microns in diameter. Any electrostatic charges on the containers induce opposite charges on the particles to attract and hold the particles on the container walls. To remove particles adhering to the walls, these opposite charges must be neutralized. Neutralizing the charges is difficult, however, because the charges holding each dust particle to a container wall are shielded by the dust particle itself. Moreover, once the electrostatic forces have been momentarily abated, the freed dust particles must be removed immediately before they re-attach themselves to the container.
  • the methods include spraying the containers with cold or hot water, utilizing ozone or ozonated water as a sanitizing agent, using ionized gas streams to rinse containers, and using combinations of air and water for rinsing.
  • a pan inverting and/or cleaning system is disclosed in US 2010/0094454 A1 .

  • the air conveyor has a track assembly and an air source.
  • Containers are movably supported by the track assembly and the air source moves the containers along the track and past the air nozzles and vacuum members.
  • a method for assembling an air rinsing system for containers comprises providing an air source for use in rinsing the containers and connecting a manifold to the air source.
  • the manifold comprises a manifold inlet, an ionization unit, and a manifold outlet.
  • the method further comprises placing the ionization unit within the manifold, such that during operation, air is ionized before exiting the manifold outlet.
  • a method for air rinsing bottles comprises providing an air source, receiving air from the air source at a manifold connected to the air source, the manifold comprising a manifold inlet, an ionization unit, and a plurality of manifold outlets, ionizing the air within the manifold with the ionization unit before the air exits the manifold outlets, expelling ionized air from the manifold through the plurality of manifold outlets, and passing a bottle over or under the plurality of manifold outlets, and the ionized air from the plurality of manifold outlets assists in removing particles from the bottle.

  • Two openings one of which is shown in FIG. 16A , are disposed at either longitudinal end of the enclosure 1022, which are required to permit the passage of the bottles 1040.
  • the enclosure 1022 can be provided with two plexiglass doors 1340A and 1340B.
  • the plexiglass doors 1340A and 1340B can be provided with handles 1342A and 1342B for easy access to the inside area of the enclosure 1022 for maintaining the system.
  • the rinsing system 1010 can be provided with an air source to provide air to the containers 1040.
  • HEPA filters can be placed at the air source inlet and outlet for filtering any unwanted particles from the air.
  • a 0.3 ⁇ (99.9% efficiency) HEPA filter or pre-filtering assembly can be added to the air source inlet to screen off microorganisms from the supply air and a 0.5 ⁇ (99% efficiency) HEPA filter can be added to the outlet of the air source as a preventative measure for any unforeseeable debris from the air source.
  • the embodiments disclosed herein could be implemented with any air source known in the art.
  • the nozzles 1301 can be provided with internal ionization units within a nozzle manifold 1303, which can be configured to ionize the air before the air exits the nozzles.
  • the nozzle array 1300 can be mounted on the nozzle manifold 1303. As shown in FIGS. 16A and 16B , the nozzle array height can be adjusted up and down by height adjustment screws 1326.
  • the air nozzle array is mounted to an adjustable bracket 1328, which has slots 1330 and guide pins 1332 for adjusting the height of the nozzle array 1300 with respect to the bottles 1040 and grippers 1039.
  • Air from the air source is exposed to the air ionizing units, which ionize the air for assisting with removing particles from the passing containers. After the air is ionized it is directed into the nozzles. As can be observed from this arrangement, the air is ionized before reaching and exiting the nozzles. This enhances cleaning, creates a reliable and durable source for ionized air, and creates a system that is easy to maintain.
  • the rinsing system 1010 can also be equipped with a vacuum system 1100 for vacuuming unwanted particles from the bottles 1040 as they move on the conveyor 1012.
  • the vacuum system 1100 comprises a vacuum pan 1101, which extends underneath the bottle flow path and underneath the air manifold 1300.
  • the vacuum pan 1101 is essentially in the form of a trough that becomes shallower in the direction of the bottle flow path, as shown in FIG. 16B .
  • the trough is folded, and at the point adjacent and directly beneath the ionizing nozzles 1301, is connected, for example, by screws 1102 to a vacuum duct 1104, which in one embodiment is in the form of a cylinder as shown in FIG. 16A .
  • the vacuum system 1100 can be provided with two elbow shaped-manifolds or vacuum manifolds 1108, which each have suction inlets 1106.
  • the vacuum manifolds 1108 are located on either side of the manifold 1303 for vacuuming unwanted particles from the system.
  • the vacuum manifolds 1108 can be provided with diverging portions 1110 for expanding the vacuumed area inside of the housing 1022.
  • the vacuum duct 1104 is connected to the duct 1019, (shown in FIG. 1 ) which is in fluid communication with a vacuum source or air source (not shown) that provides a suction or vacuum force to the environment within the housing 1022, where the nozzle array 1300 is contained.
  • the vacuum system 1100 which is powered by the vacuum source, continually evacuates the air within the housing 1022, together with any floating ionized dust or other particles that have been removed from the surfaces of the bottles 1040 through the suction inlets 1106. In addition, to helping extract the floating ionized dust or other particles that have been removed from the surfaces of the bottles 1040, the vacuum system 1100 also helps in removing dirty air from the rinsing system 1010.
  • the vacuum system 1100 can form part of a closed loop system in that the air extracted by the vacuum can be filtered by a HEPA filter and recycled back to the air source and then provided to the nozzle array 1300 for use in rinsing the bottles 1040 in the cleaning process.
  • a separate vacuum source can be used, such as a Dayton model 2C940 blower. In either instance, the inlet of the source is attached to the vacuum duct 1019.
  • An electrical control panel interacts with plant PLC, which enables the air source to run at an optimal fan rate depending on the particular bottle size and conveyor speed. Additionally, the electrical control panel (not shown) is electrically connected to the nozzles disposed on the nozzle array 1300 within the bottle cleaning station 1020 to provide operator control.
  • the rinsing system 1010 is also equipped with sensors at key locations for ensuring cleaning performance. Upon detection of an error in the system, for example, low air pressure, improper filtration, or a non-functioning ionizer, the system can be configured to give a warning signal to the operator and can be configured to shut down operation. In any of the above embodiments, if any of the sensors connected to the vacuum members or the nozzles senses a lack of suction or a lack of air pressure respectively, the system is automatically shut down via an automatic shut-off switch.
  • the cleaning system 1020 cleans the inside of the bottles 1040 as they are transported through the rinsing system 1010.
  • the bottles 1040 are transported through the rinsing system 1010 so that each bottle 1040 traverses the various stations, for example, the bottle gripping station (not shown) and the bottle cleaning system 1020.
  • the conveyor arrangement 1012 transfers the bottles 1040 so the bottle flow path follows the direction of the arrows, and as a result of the bottle path passing around a large pulley rotating wheel 1014, the bottles 1040 become inverted in a generally upside down position with the opening being downwardly directed, as shown by bottle 1040 in FIG. 15 .
  • the bottles 1040 are preferably held in the conveyer arrangement by the finger grippers 1039 (shown in FIG. 16A ).
  • air is directed inside the bottles 1040 by the nozzles 1301 on the nozzle array 1300. This has the effect of discharging any particles located inside the bottles 1040.
  • the pressure of the air exiting the nozzles can be regulated at the air source and can be manipulated by any suitable methods known in the art. It may be desired to customize the pressure of the air based on the type and/size of the bottle being cleaned.
  • the vacuum system 1100 which continually evacuates the air within the housing 1022, evacuates any floating ionized dust or other particles that have been removed from the bottles 1040. Consequently, tiny particles that have been displaced from the bottle surfaces that remain entrained in the air within housing 1022 are evacuated from the bottle environment and are no longer available to re-adhere to the surface again in the event they become de-ionized. Additionally, the vacuum can be applied such that a negative pressure is maintained across the system. This helps prevent dirty air from being blown into the environment surrounding the system and prevents the dirty air from contaminating the surrounding environment and equipment.
  • the container rinsing system of the present disclosure provides several advantages.
  • the container rinsing system utilizes much less electric energy than traditional air systems (less than half of the electric energy) to air rinse empty bottles. It is robust, leads to less down time of the bottling operation, and requires less maintenance than preexisting systems.
  • the system is an air-only system as opposed to a water-based system or combination air/water system, the system uses fewer natural resources such as water and electricity.
  • the rinsing system also has a small footprint saving on facility space. Previous designs required a larger footprint and more structure and components. The design also allows the nozzles to be positioned closer to the bottle finish enhancing rinsing capabilities. Because the system components, including the housing and conveyor, can be easily adjusted, rapid change-over of the system is achieved for differently-sized bottles. Use of the ionizing air nozzle neutralizes resources such as water and electricity.
  • the rinsing system also has a small footprint saving on facility space. Previous designs required a larger footprint and more structure and components.
