Definitions

  • the invention relates to a multi-channel blow nozzle, with a housing that has a nozzle outlet with row-arranged nozzle channels at one end and an opening for gas or air supply at the opposite (rear) end.
  • Nozzles of the aforementioned type are primarily used for blowing out containers, housings and the like, for cooling and cleaning materials and for blowing away or specifically transporting small parts. Compressed air is the primary medium. However, it is at least conceivable to use other gases or gas mixtures.
  • DE-PS 24 13 614 also shows a similar compressed air-fed multi-channel nozzle with rows of individual nozzle channels lying next to one another.
  • the nozzle according to the above publication is - in contrast to the nozzles according to the prior art mentioned above - as a plastic injection-molded part, consisting of two identical or glued together different sized halves.
  • the individual nozzle outlet channels can each be formed as semicircular grooves in the two nozzle body halves by injection molding.
  • a juxtaposition of several nozzles to form a multiple nozzle device can be seen from the brochures mentioned at the beginning.
  • a common pipe is used for the compressed air supply, on which the individual multi-channel nozzles are installed next to each other - at right angles to the pipe axis.
  • the individual nozzles are firmly connected to the common compressed air supply pipe, so the multiple nozzle device is designed as a fixed distributor block.
  • the object is achieved in a multi-channel blowing nozzle of the type mentioned in the introduction in that the housing has two mutually parallel side walls and in that a connecting recess is arranged on one side wall and a hollow cylindrical connecting piece is arranged on the other side wall, flush with the connecting recess, whose outer diameter is smaller than that Diameter of the connecting recess, such that a plurality of housings can be arranged in a row next to one another, the connecting piece of the one housing engaging in a sealing manner in the adjacent connecting recess of the adjacent housing, and the connecting recess and connecting piece can each be sealed by a side part.
  • the invention enables a simple plugging (and loosening) of the individual nozzles, but at the same time also causes a cross-connection of the compressed air supply from housing to housing, so that a pressure medium supply to only a single housing of the multiple nozzle arrangement is required.
  • the possibility (which may be available in the case of multiple nozzle arrangements with an extremely large overall width) is in no way excluded to supply pressure medium to a second (or further) individual nozzle of the overall arrangement if necessary.
  • the compressed air connections of the individual housings that are not required can be sealed in a simple manner by means of appropriate blind closures.
  • the respective outer side surface of the multiple nozzle arrangement or - when used as a single nozzle - both side surfaces of the housing can be easily and effectively closed by the side part according to the invention.
  • a multi-channel blowing nozzle with a nozzle chamber extending between the gas or air supply opening and the nozzle outlet (nozzle channels)
  • an intermediate wall with through-openings for the medium in the nozzle chamber transversely to the direction of supply of the gaseous medium .
  • the partition is expediently arranged closer to the gas or air supply opening than to the nozzle outlet. It preferably adjoins the connecting recess and connecting piece in such a way that a channel-like housing section results between the connecting recess and connecting piece.
  • the defined passage openings in the intermediate wall two of which are preferably provided and arranged symmetrically to the gas or air supply opening, advantageously have the effect that only as much gas or air passes through to the nozzle outlet (nozzle channels) as is necessary. This ensures the distribution of the gaseous medium supplied over a longer row of individual nozzles assembled to form a multiple nozzle arrangement.
  • the partitioning according to the invention with a few passage openings also has the further advantageous effect that the noise emitted by the blowing nozzles or by the multiple nozzle arrangement is reduced by approximately 10 dB. Subjectively, this corresponds to halving the volume.
  • the multiple nozzle arrangement shown in FIG. 1 consists of three mutually identical individual nozzles 10, 11 and 12, which form the basic elements of the plug-in system, and two lateral, different connecting elements 13, 14.
  • the individual nozzles 10, 11 and 12 each have an approximately rectangular shape / cuboid housing 15, in which on the one hand a connection opening 16 for gas or air supply and on the other hand several rows next to each other arranged nozzle channels 17, which form the nozzle outlet, are incorporated. Between the gas or air supply 16 and the nozzle outlet 17 extends - like the nozzle housing 15 itself approximately cuboid - nozzle chamber 18.
  • the nozzle housing 15 also has two mutually parallel side walls 19 and 20. On one side wall 19 is laterally protruding a hollow cylindrical connecting piece 21 is formed.
  • the other side wall 20, on the other hand, has a connecting recess 22, which has a larger diameter than the connecting piece 21, but is arranged flush with the latter in the nozzle housing 15.
  • Fig. 1 also shows that in the multiple nozzle arrangement shown, each individual nozzle engages with its connecting piece 21 in the adjacent connecting recess 22 of the adjacent nozzle. To seal this connection, a sealing ring 23 surrounding the connecting piece 21 is provided. In this way, any number of nozzles can be put together to form a multiple nozzle arrangement.
  • the end elements 13 and 14 already mentioned form side parts of the multiple nozzle arrangement, as a result of which it is sealed on both sides.
  • the one side part 13 has a recess 24 into which the connecting piece 21 of the adjacent nozzle 10 engages.
  • the diameter of the recess 24 in the side part 13 corresponds to the diameter of the connection recesses 22 provided in the nozzles. Sealing is also carried out in a corresponding manner by an O-ring 23.
  • an extension 25 is formed on the inner surface of the other side part 14, one has the diameter corresponding to the diameter of the connecting piece 21 of the nozzle.
  • the extension 25 engages in the connecting recess 22 of the laterally adjacent nozzle and is in turn sealed against this by an O-ring 23.
  • the supply connection 26, which forms a separate part and is detachably arranged in the relevant opening 16 of the nozzle housing 15, can also be connected accordingly at any time to one of the other two nozzle housings.
  • annular groove 34 is incorporated, which serves to receive the sealing O-ring 27.
  • a corresponding annular groove also has the supply connection 26 and the blind plug 28 on its outer circumference.
  • This ring groove is numbered 35.
  • the interaction of the O-ring 27 with the annular grooves 34, 35 advantageously creates a snap connection which enables a durable connection between the supply connection 26 or the blind plug 28 and the nozzle housing 15.
  • the supply connection 26 or the blind plug 28 can also be connected in some other way to the nozzle housing 15, which e.g. can be done by gluing, screwing or by means of a bayonet lock.
  • the nozzles 10, 11 and 12 are designed or manufactured as injection molded parts, it is also conceivable to design the injection mold in such a way that the nozzle housing 15 can be produced either with a molded-on supply connection or without one.
  • an intermediate wall 30 which is transverse to the feed direction 29 of the gaseous medium is arranged in the nozzle chambers 18.
  • the drawing makes it clear that the partition walls 30 are arranged closer to the gas or air supply opening 16 than to the nozzle outlets 17. In the exemplary embodiment shown, they lie directly adjacent to the connecting recess 22 and connecting piece 21, so that a channel-like housing section 32 extending in the transverse direction 31 results.
  • two comparatively small-caliber through openings 33 are incorporated in the partition walls 30.
  • a distribution of the gaseous medium supplied at 26 is within the Multiple nozzle arrangement guaranteed over a larger number or longer row of nozzles.
  • the defined through openings 33 in the intermediate walls 30 simultaneously ensure that only as much gaseous medium reaches the nozzle outlets 17 as is necessary for the particular application.
  • the partitioning of the nozzle chambers 18 by means of the intermediate walls 30 provided with relatively small-caliber through openings 33 also has the additional advantageous effect that the noise emitted to the outside by the nozzles is limited to a minimum.
  • each nozzle housing has a connecting tab 36 on one side, which has a bore for inserting a fastening screw 37.
  • a recess 38 corresponding to the contours of the connecting bracket 36 is machined with a threaded bore 39 for the fastening screw 37.
  • the side parts 13 and 14 are also connected mechanically in a corresponding manner to the adjacent nozzles — in the exemplary embodiment shown, the nozzles 10 and 12.
  • the side part 14 has a connecting tab (not shown) which interacts with the depression 38 of the adjacent nozzle 12.
  • the other side part 13 has a cutout (not shown) corresponding to the contours of the connecting lugs 36, into which the connecting lug 36 of the adjacent nozzle 10 engages.
  • the preferred production method for the nozzles 10, 11 and 12 assembled to form the multiple nozzle arrangement shown is the injection molding method, a thermoplastic material being used as the material.
  • the top of the nozzle housing 15, which is numbered 15a and 15b in FIGS. 2 and 3, should be manufactured separately from the bottom 15c.
  • the parts 15a and 15c or 15b and 15c can then be connected to one another in a sealed manner by gluing or welding.
