Definitions

  • the invention relates to a spraying device for bottle washers with a cylindrical nozzle shaft which rotates in batches and is arranged outside a spray box supplying the spray liquid, the nozzles of which run perpendicular to the axis of rotation and one or more nozzles are provided next to one another for one spray position and are aligned crosswise to one another at a distance.
  • bottles to be cleaned are preferably held in cells arranged in cell carriers and transported through the individual treatment zones. After the end of the treatment process, rinsing and rinsing then take place, in which the bottles in the cells with their mouths are moved downwards via spraying stations which run across the machine and have a spray nozzle for each row of bottles. It is known to use rotating nozzle tubes or shafts as spraying devices, which are rotated batchwise by the bottle carriers depending on the feed speed of the chains moving them, so that the spray jet strikes the bottle mouth.
  • a spray device has become known in which a nozzle shaft is provided which is crosswise has arranged nozzle bores which can be brought into a spraying action by means of a rotary star. These nozzle bores are arranged at a distance from one another and are arranged off-center of an outlet opening which points centrally to the bottle mouth. With a corresponding rotation of the drive star or the nozzle shaft, a nozzle bore, which is offset to the left of the bottle mouth in the direction of movement of the bottles, and the nozzle bore, which runs crosswise and is aligned to the right of the center of the bottle mouth during the next spray cycle.
  • the nozzle bores are always aligned laterally to the center of the bottle mouth passed over them.
  • the bottle mouths can be so far outside the area of the respective nozzle bores that an exact spraying cannot be carried out. It cannot be ruled out that one or the other bottle will not be sprayed out in the required manner. This is particularly dangerous in the beverage industry, where the bottles are then filled with drinks.
  • the reusable bottles pass through different lye departments during their treatment. It must therefore be ensured that such residues do not remain in the bottle to be filled afterwards.
  • two or more nozzles are provided next to one another for each spray position and, in addition to these, at least two crosswise nozzles which are rotatably supported in their axial movement in such a way that the nozzle opening in each injection action is in any position can be moved to a vascular mouth passed over it.
  • the nozzle opening or the spray jet emerging therefrom can be carried along to the bottle carried over it during a spray cycle and can be guided relative to this movement at least partially by axial displacement of the nozzle body through the container cavity in the sense of a spatial spray jet curve.
  • the invention is based on the object of creating an exact center spray with crosswise offset bores and with spherical spraying, which enables a spatial loading of the container interior by axial displacement, to reduce the displacement of the jets located next to one another and thus an even more precise spatial path of the spray jet ensure.
  • this object is achieved in that the nozzle bores which are offset in a rotating circle are arranged in a cross-sectional plane in the nozzle shaft.
  • the crosswise arrangement of the nozzle bores in one plane provides a particularly exact center injection in the case of stationary nozzle bores.
  • a particularly advantageous guidance of the axial displacement path is ensured in the case of displaceably mounted nozzle bores.
  • the spray device consists of a preferably rectangular spray box 1, which is arranged transversely to the direction of movement 2 of the bottles 3 in a cleaning machine, not shown.
  • this spray box 1 are Screwed bearing blocks 4, which serve to actually accommodate the nozzle body 5, which is expediently designed, as the exemplary embodiment shows, as a continuous nozzle shaft.
  • the nozzle shaft has 5 nozzle bores I and III and further nozzle bores II and IV offset from these bores by 90 °.
  • the nozzle bores I and III offset in a rotating circle are arranged in the same cross-sectional plane in the nozzle shaft, the bores crossing in the axis of the nozzle shaft.
  • the nozzle bores III and IV are likewise arranged in the same common cross-sectional plane of the nozzle shaft 5 and also intersect in the nozzle shaft axis.
  • the mutually offset nozzle bores intersect outside the axis of the nozzle shaft, so that in this way different spray jet angles and different spraying processes can be achieved with a corresponding rotation of the nozzle shaft. This enables any adjustment to the respective conditions.
  • the nozzle shaft is mounted according to the embodiment shown in Fig. 1 in the bearing blocks 4, which in turn have a lower feed opening 6 for the spray liquid and are formed in the outlet region 7 of the spray jet so that it can cover a certain angular range when the nozzle shaft rotates, ie , in the direction of travel 2 of the bottles 3 can be moved with them, although the actual spray box 1 is arranged in a stationary manner.
  • the spray liquid occurs thereby through a bore 8 of the spray box into the area of the feed opening 6 of the bearing block 4 and from here as a targeted spray jet through one of the nozzle bores I to IV above it to the outside.
  • the spray liquid itself is supplied to the spray box 1 laterally or at a suitable point under pressure, so that liquid is constantly applied to it.
  • the spray jet Due to the rotation of the nozzle body or the nozzle shaft 5, the spray jet only reaches the outside when it reaches the upper outlet region 7 of the bearing block 4.
  • the bottle 3 is located, for example, on the left side of the spray box 1 shown in cross section in the plane of the drawing.
  • the bottle then moves further to the right side of this spray box, whereby a rotation of the nozzle shaft 5 is also caused by bottle baskets, not shown , so that the spray jet constantly moves with the bottle 3 and hits it from different angular positions.
  • the nozzle bore II offset by 90 ° comes into action in the subsequent row of bottles, which is also centered in the center of the bottle mouth above it without displacement of the nozzle shaft.
  • the axial movement of the nozzle shaft 5 also occurs at the same time as the nozzle shaft 5 rotates.
  • This axial displacement of the nozzle shaft 5 is brought about by adjusting devices, not shown, which are arranged, for example, at the end of such a nozzle shaft 5 and as a cam control disk or the like. can be trained.
  • adjusting devices not shown, which are arranged, for example, at the end of such a nozzle shaft 5 and as a cam control disk or the like. can be trained.
  • any desired spray jet procedure can now be achieved through the bottle located above it.
  • the adjusting device is designed such that first, according to the exemplary embodiment in FIG.
  • the nozzle bore I then without lateral displacement of the nozzle shaft 5, the nozzle bore II, then with the lateral displacement beginning, the nozzle bore III and finally when the nozzle shaft remains in this second position the nozzle bore IV is set to spray.
  • the nozzle bore I comes into action again, which is brought about by pushing back and rotating the nozzle shaft into the original position.
  • the nozzle bore II is then used again, then by slightly shifting the use of the nozzle bore III and the nozzle bore IV. In this way, a further improved spraying of the bottles passed over the spray box 1 is achieved. If you do not want to move the nozzle shaft, only holes I and II can be used, which are then used after their rotation by 180 nach with their opposite openings.
  • each spray jet must have its own uninterrupted nozzle bore so as not to limit the effect of the spray jet.
  • the invention it has been shown by the invention that, when the nozzle bores are arranged crosswise in the same drilling plane, there is no swirling or the like of the spray jet and this reaches the bottle cavity in a perfectly constant jet effect.
