Definitions

  • the invention relates to a nozzle arrangement of the type mentioned in the preamble of claim 1.
  • bottles When reusable bottles are cleaned before they are refilled, the bottles are soaked in baths and sprayed from the outside and especially from the inside in spraying stations. New bottles are also often sprayed inside before they are filled. In the case of internal spraying, a liquid jet is directed into the inside of the bottle, which is to capture and rinse out as many areas of the inner surface as possible. If possible, any stubborn dirt residues should be rinsed out safely.
  • the bottles are suspended from a nozzle arrangement which injects into the bottle from below, so that the liquid can run out of the bottle again downwards.
  • Nozzle arrangements of the type mentioned at the outset have a rotationally driven nozzle body, the spray jet of which follows the mouth of a moving bottle over a certain angular range.
  • this results in the advantage that the bottles can be moved continuously in a bottle cleaning machine, whereby they are sprayed out over a longer period of time in the swivel range of the jet.
  • this also results in Significant advantage that the spray jet enters the bottle at different angles over its swivel angle range and thus strikes different wall areas in the bottle. This results in intensive cleaning at different points of impact of the jet in the bottle.
  • the nozzle body can pivot with the nozzle tube, for example in a reciprocating pivoting movement.
  • a construction is known in which the nozzle body rotates with respect to the nozzle tube, one end or the other of the bore alternately pointing outwards towards the bottle.
  • the bores are directed perpendicular to the axis of rotation and thus generate a spray jet which pivots in the plane perpendicular to the axis of rotation.
  • the points of impact of the jet in the bottle therefore run up the side wall of the bottle, centrally over the bottle bottom and down on the other side of the bottle. There may be insufficient rinsing effects on the side of the bottle.
  • the object of the present invention is to provide a nozzle arrangement of the type mentioned at the outset which flows through an obliquely spraying bore of the nozzle body alternately from both ends when the nozzle body rotates without axial displacement of the nozzle body.
  • the beam Since the hole is arranged at an angle, the beam does not swing in one plane, but on a flat cone.
  • the points of impact of the swiveling beam in the bottle therefore do not run centrally over the bottle base, but, depending on the size of the oblique angle, more or less high in a curved path over the side wall of the bottle. If the angle of inclination deviates very slightly from the vertical, the points of impact of the beam can also run a short distance over the bottom of the bottle.
  • the cleaning effect can be significantly improved in accordance with the individual bottle shape and its special cleaning and flow problems.
  • the bore is kinked in itself, so that when the nozzle body is rotated through 180 °, the bore injects again in the same direction. Without the need to axially offset the nozzle body during its rotation, the bore can be flowed through alternately in both directions in order to achieve the desired self-cleaning effect, as in the construction of DE-PS 24 02 630.
  • FIGS. 1 and 2 show in cross section and in longitudinal section a spray tube 1 with a nozzle body in the form of a nozzle shaft 2, which is arranged rotating about the axis A.
  • the nozzle shaft 2 is mounted on the outer edge of a flange 3 which is adapted to the nozzle shaft.
  • the nozzle shaft 2 thus closes the opening 4 of the spray tube 1 surrounded by the flange 3.
  • the nozzle shaft 2 is held on the flange 3 by a bracket 5 which, as the figures show, has a corresponding passage above the opening 4.
  • the nozzle shaft 2 has a bore 6 which, according to the prior art, is perpendicular to its axis of rotation A.
  • the end of the bore 6 towards the spray tube 1 is placed in connection with the opening 4 over the angular range indicated in FIG. 1, so that liquid under the pressure in the spray tube 1 through the opening 4 and the bore 6 emerges in the form of a spray jet, which is shown in three swivel angles with the arrows a, c and e in FIG. 1.
  • a bottle 7 with a mouth 8 is moved past the nozzle arrangement shown, in the direction of the arrow according to FIG. 1. In FIG. 2, this corresponds to a movement perpendicular to the plane of the drawing.
  • the rotary drive of the nozzle shaft 2 takes place synchronously with the transport movement of the bottle 7.
  • the nozzle shaft rotates in the direction of rotation shown by an arrow in FIG. 1.
  • the first jet a After opening of the bore 6 through the opening 4 of the spray tube 1, the first jet a thus hits the bottle at the angle shown.
  • the last jet e shortly before the bore 6 is closed by the flange 3 strikes the bottle at an opposite oblique angle, which is then moved to the left in FIG. 1 so that the jet can still enter the mouth 8.
  • the jet generated by the nozzle arrangement is pivoted in a plane perpendicular to the axis A of the nozzle shaft 2, 1 in the plane of the drawing.
  • FIG. 3 shows in the sectional plane of FIG. 1 the bottle 7 with the first incoming beam a, the central beam c incident vertically upwards, the last beam e and with two beams b and d in intermediate angular positions. It can be seen here that the points of incidence of the rays a to e first run upward on the right side wall of the bottle according to FIG. 3, then over the bottom of the bottle and then down again on the other side.
  • Fig. 4 shows the manner in which the settlement takes place.
  • the side wall of the bottle is cut open in the middle in front and folded to the right and left behind.
  • the floor is folded back in the direction of the arrow. 5, in which the curve K is drawn in, on which the points of incidence of the rays lie.
  • the points of incidence of the rays a to e indicated in FIG. 3 are marked here.
  • the first point of impact is therefore at a, then runs vertically upwards on the side wall of the bottle via b to the bottom of the bottle, which it crosses in the middle, the beam c striking the center of the bottom. Then the impact points d after e on the other side wall descend again.
  • Fig. 5 the angular positions 0 ° to 360 ° of the bottle shell with respect to the bottle axis are given below.
  • the central plane of the bottle in which it is moved that is to say in the plane of the drawing according to FIGS. 1 and 3, runs through 0 ° and 180 °, as indicated in FIG. 3.
  • the 0 ° position corresponds to the line of the bottle jacket, which lies at the front in the direction of movement of FIG. 1.
  • the bore 6 is perpendicular to the axis of rotation A of the nozzle shaft 2.
  • the spray jet a to e thus swings in the plane perpendicular to the axis of rotation A, that is to say in the plane of the drawing in FIGS. 1 and 3, that is to say in the central plane of the bottle 7, which according to FIG 5 runs through 0 ° and 180 °.
  • FIGS. 1 to 2 the invention is explained in three exemplary embodiments, specifically on the basis of a spray tube construction with a nozzle shaft and bottles moved over it, corresponding to the construction of FIGS. 1 to 2, which is of completely identical design, except for the bore, which is designed differently is as the bore 6 of FIGS. 1 to 2.
  • Fig. 6 shows a nozzle shaft 12 according to the invention in the direction of Fig. 2.
  • the bore 16 is formed so that it emerges at both openings obliquely to the plane perpendicular to the axis of rotation A, that is, at both openings at the angle ⁇ shown compared to the Axis A.
  • This angle ⁇ can preferably be approximately 70 ° to 85 °.
  • the spray jets emerging from the bore 16 therefore do not pivot in a plane perpendicular to the axis of rotation A, but in a flat cone with the axis of rotation A as the cone axis.
  • the bottle 7 is transported in a slightly laterally offset transport path so that the swivel angle of the spray jet can enter the mouth 8.
  • FIG. 7 shows how the spray jets generated by the nozzle shaft 12 of FIG. 6 strike the bottle.
  • the curve of these points of impact is denoted by K '.
  • arrows also show the direction of travel of the rays lying against the wall. It turns out that apart from the jet pointing vertically upwards from point c, the jets all run more or less obliquely, that is to say run helically along the bottle wall.
  • FIG. 7 shows, when the beam is swiveled from a to e, that is to say largely all areas of the Bottle detected by the rays running against the bottle wall. These rays run against the wall, as shown in FIG. 3 by means of the ray b. If one compares with the spray pattern of FIG. 5, it can be seen that in the spray pattern shown in FIG. 5 according to the prior art, the jets lying against the wall all run on the curve K. According to the invention, as can be seen from FIG. 7, the rays run helically in different directions and essentially cover the entire inner wall of the bottle.
  • FIGS. 8 and 9 show a variant of the embodiment of FIGS. 6 and 7.
  • a bore 26 is provided in the nozzle shaft 22, in which the angle ⁇ (see FIG. 6) is larger, that is to say closer to 90 °.
  • the curve K '' of the spray jet impact points here runs somewhat slimmer than the curve K 'according to FIG. 7 and extends higher. The middle part of the curve runs over the ground.
  • a comparison of FIGS. 7 and 9 shows how the spray pattern in the bottle can be changed by varying the angle ⁇ of the bores. Depending on the bottle shape (slim and long, thick and short), the spray pattern can be adapted to the requirements.
  • FIG. 6 shows a nozzle shaft 32, which has two bores 36.1 and 36.2 at a distance on the axis of rotation A, which are each symmetrically obliquely directed in the opposite direction.
  • the jets generated by these bores hit the same bottle 7.
  • Fig. 12 shows the curves of the beam impact points in the development of the bottle.
  • the rays generated by the bore 36.1 meet on the curve K 1 with the points of incidence a 1 to e 1.
  • the rays of the bore 36.2 on the curve K2 with respect to the through 0 ° and 180 ° running center plane of the bottle is exactly symmetrical.
  • FIG. 12 The particularly intensive spray pattern of FIG. 12 can be achieved instead of the construction of FIGS. 10 and 11 also with a construction of the nozzle shaft which is designed with only one bore according to FIGS. 6 or 8. There are then two nozzle shafts to be arranged one behind the other on the transport path of the bottle, which spray in the opposite oblique direction. Then the one nozzle shaft (see Fig. 12) on the curve K1 and the subsequent nozzle shaft on the curve K2 spray.
  • nozzle shafts are shown which preferably have a plurality of bores 16, 26 or pairs of bores 36.1, 36.2 over their length.
  • Such nozzle shafts can be used in bottle cleaning machines of conventional design, in which in long bottle baskets Bottles are moved in parallel on a large number of parallel bottle conveyors.
  • a nozzle body with only one hole or a pair of holes is sufficient.
  • nozzle body instead of rotating the nozzle body on a spray tube, it can also be fixed on it and pivoted with it, for example back and forth.
