Definitions

  • the present invention relates to a spraying device.
  • the invention is concerned with a spraying device of the type used for the cleaning of bottles e.g. in bottling operations by which bottles are filled with a pourable product.
  • a typical unit for cleaning bottles in a beverage bottling plant comprises a plurality of operating stations, including one or more washing stations, a rinsing station and a cooling section. Furthermore, a cleaning unit of this type comprises transport means for: receiving the bottles to be cleaned at an input station; conveying the bottles along a bottle path which sequentially crosses each one of the operating stations; and for delivering cleaned bottles at an output station.
  • Washing stations and rinsing station are defined mostly by respective baths, wherein bottles are first brought into contact with cleaning agents (i.e. the chemicals in aqueous solution referred to above) and then rinsed for removing any possible residue of those chemicals.
  • cleaning agents i.e. the chemicals in aqueous solution referred to above
  • the speed at which the bottles are advanced along their path by the transport means is such that the permanence time of bottles in each bath is enough to achieve the desired cleaning effect.
  • the transport means typically consist of a conveyor which, in a cooling path portion P cool of path P conveys the bottles head first, i.e. with the opening facing downwards.
  • the conveyor comprises a plurality of bars, each of which carries a respective plurality of bottle holders.
  • bottle holders are in the form of bottle baskets, each of which is adapted to receive and convey a respective bottle.
  • the bars are driven, typically by means of a pair of parallel chains arranged about respective drive systems, along a closed loop which substantially replicates, in a relative portion connecting the input and output stations, the bottle path P.
  • the transport means are continuously cycled through the various parts of the cleaning unit to permit a substantially uninterrupted operation thereof and, thus, an essentially constant throughput of a substantial number of bottles to meet the needs of high-speed bottling plants (in certain instances, these machines may process as many as 150,000 bottles per hour).
  • bottles are then conveyed through the different baths of the operating stations and reach the rinsing and cooling stations, where they are reached by jets of water aiming at rinsing both their inner and outer surface as well as at lowering their temperature in order to prepare them for subsequent operations (typically filling, labelling, capping).
  • a cleaning unit typically comprises (see, for reference, Figure 1 ) spraying devices 100 of the type comprising: a main conduit 101 for the supply of a washing liquid, said conduit 101 being fastened to a frame of the cleaning unit and hydraulically connected to a source of water (not shown); and a rotating body 102 defining a plurality of nozzles 103 through which water, supplied from conduit 101, is intermittently sprayed towards the bottles.
  • spraying devices 100 of the type comprising: a main conduit 101 for the supply of a washing liquid, said conduit 101 being fastened to a frame of the cleaning unit and hydraulically connected to a source of water (not shown); and a rotating body 102 defining a plurality of nozzles 103 through which water, supplied from conduit 101, is intermittently sprayed towards the bottles.
  • Main conduit 101 essentially consists of a manifold adapted to receive water at a given pressure and to distribute it at a number of outlets arranged along its length to which respective tubular junction elements 104 are fastened.
  • rotating body 102 generally consists of a radially bored cylinder, wherein each through hole defines a nozzle 103.
  • rotating body 102 comprises a set of as many nozzles 103 as there are junction elements 104.
  • rotating body 102 contains a second set of as many nozzles 103 as there are junction elements 104, defined by through holes forming an angle smaller than 180° (e.g. of 90°) with the through holes defining the first set of nozzles 103.
  • nozzles 103 are alternately put in and out of hydraulic connection with conduit 101, thereby alternately enabling and disabling the supply of respective jets of water.
  • EP1728565 discloses a spraying device wherein the junction elements 104 have a lateral surface 105, a surface 106 for contact with the manifold main conduit and a polished surface 107 for sliding contact with the cylindrical rotating body 102, and internally define a passage 108 for the washing liquid.
  • the junction elements 104 are shaped so that the polished sliding contact surface 107 completely adheres to the outer surface of the rotating body 102, whereas it is substantially welded and joined to the main manifold conduit 101 at a relative outlet.
  • exit of the washing liquid through a given nozzle in the cylindrical rotating body is enabled solely when the cylindrical rotating body forms a given angle relative to the corresponding junction element, i.e. upon alignment of the nozzle with the passage internally defined by the junction element.
  • liquid-tight contact is achieved in the area surrounding the openings of nozzles 103 when they align with the channels internally defined by junction elements 104.
  • Spraying devices of this type are often affected by drawbacks such as the accumulation of dirt and residues contained in the washing liquid.
  • drawbacks such as the accumulation of dirt and residues contained in the washing liquid.
  • dirt particles accumulate in it up to a threshold value.
  • junction element Besides, the need to achieve and ensure a proper liquid-tight adherence between junction element and rotating body makes manufacture of the sliding contact surface of a junction element very complex and costly, because of the high precision standards required. It is necessary that the materials used for the manufacture of these parts be highly rigid, therefore, whenever the two parts are not perfectly matching, leaks are bound to occur.
  • This object is achieved by a spraying device as claimed in claim 1.
  • FIGS 2 and 3 illustrate schematically a junction element 104' operatively coupled with a manifold conduit 101 and a cylindrical rotating body 102 in a spraying device 1' of the type described above.
  • the description given in the following shall not cover in detail certain constructional aspects of the spraying device 1' which virtually reproduce corresponding features already described above with reference to spraying device 1 according to the prior art. Therefore, wherever possible, when describing spraying device 1', the same reference numbers shall be used for parts that are identical or functionally alternative to corresponding parts of spraying device 1 described above.
  • Junction element 104' has a tubular structure extending along a relative axis H and internally defining a passage 108 of the same axis.
  • junction element 104' has a first open end 109 adapted to cooperate with, and releasably fixable to (e.g. in snap-on fashion), manifold conduit 101 at a relative outlet, so that washing liquid flowing in manifold conduit 101 can be received into passage 108.
  • first open end 109 is adapted to receive and hold an O-ring for sealing purposes, so that a liquid-tight connection can be achieved between junction element 104' and manifold conduit 101.
  • junction element 104' has, opposite first open end 109, a second open end 110 defining a surface 111 facing, in use, cylindrical rotating body 102 and adapted to cooperate with it in liquid-tight sliding contact at least at a relative first portion 112 extending annularly about the relative opening 113.
  • first portion 112 of surface 111 is substantially cylindrical, so as to match and completely adhere to the outer surface of cylindrical rotating body 102 and has a polished finish.
  • While rotating, cylindrical body 102 is pressed against junction elements 104' so as to obtain, at the relative first portions 112, a liquid-tight contact. Accordingly, exit of the washing liquid through a given nozzle 103 in cylindrical rotating body 102 is enabled solely when cylindrical rotating body 102 forms a given angle relative to the corresponding junction element 104', i.e. upon alignment of nozzle 103 with the passage internally defined by junction element 104', i.e. with the relative opening 113.
  • surface 111 comprises a second portion 114 substantially adjacent to first portion 112 and adapted to cooperate with play with the outer surface of cylindrical rotating body 112, a segment 115 of an annular gap being thereby defined between said second portion 114 and the cylindrical body 102.
  • second portion 114 may comprise a surface having a substantially cylindrical structure with a diameter slightly greater than the diameter of cylindrical body 102.
  • opening 113 has an oval-shaped cross-section, which is designed to be operatively coupled with a pair of nozzles 103 defined by corresponding through holes in rotating body 102, the relative axes of the through holes forming an angle smaller than 180° and lying in respective parallel planes slightly apart from one another, as in the prior art arrangement illustrated in Figure 1 .
  • the cross-section of opening 113 may have a different shape, e.g. circular, especially in the case where only one nozzle 103 is provided for every outlet in main conduit 101.
  • junction element 104' preferably comprises, at second open end 110, anti-rotation means 117 symmetrically arranged relative to axis H and configured to cooperate with play with the outer surface of rotating body 102 so that proper positioning of surface 112 of junction element 104' relative to rotating body 102 is ensured upon rotation of the latter.
  • anti-rotation means 117 With the first portion 112 of surface 111 not be correctly positioned relative to rotating body 102, i.e. were the relative cylindrical surface not properly matching and in misalignment, cooperation of anti-rotation means 117 with rotating body 102 upon rotation of the latter would cause the rotation of junction element 104' about the relative axis H until achievement of the correct positioning, without any intervention on the part of an operator.
  • proper alignment of opening 113 of second open end 110 with the axis of a corresponding nozzle 103 is ensured upon rotation of rotating body 102.
  • anti-rotation means 117 may substantially consist, as in the embodiment shown in Figures 2 and 3 , of two pairs of projections arranged on opposite sides of second portion 114. Each projection 117 defines a respective end cylindrical surface. Each end cylindrical surface lies substantially in a plane transversal to axis H.
  • junction elements 104' are fastened to (e.g. snapped on) manifold conduit 101 in perfect alignment relative to the longitudinal axis thereof.
  • anti-rotation means 117 arranged on both sides of rotating body 102, as soon as the spraying device is activated - i.e. as soon as motor means initiate rotation of body 102 about its axis - junction elements 104' shall be, accordingly, rotated to assume the proper alignment relative to nozzles 103 of rotating body 102.
  • anti-rotation means 117 ensure that, in use, the correct alignment is maintained, which also results in the gap 115 between second open end 111 of junction element 104' and rotating body 102 to be maintained. Accordingly, dirt particles and impurities which tend to accumulate there may easily be removed without the operator needing to turn the spraying device off and to disassemble rotating body 102 and junction elements 104' for accessing the relative interface at which dirt and impurities have accumulated.
  • junction elements 104' according to the description given above can conveniently be manufactured by moulding, 3-D printing and similar processes.
