Definitions

  • the invention relates to a device for the suspended guiding of material webs or sheets of material to be conveyed, with nozzles fed with blown air in a nozzle body, each of which has a sunk surface in the nozzle body and inclined to the outside of the nozzle body, for the blowing air jet emerging from the nozzle opening.
  • nozzles have been developed which, due to their geometric design, guarantee a defined outflow of the blown air (DE-PS 19 07 083). These nozzles are formed by an arcuate incision in the nozzle body, the area lying inside the arc being a tongue-shaped nozzle lip in the plane of the surface of the nozzle body, while the area lying outside the arc is lowered in a trough-like manner.
  • the object of the invention is to provide a device for the suspended guiding of material webs and sheets to be conveyed, which has a higher contact security than the known device.
  • the device according to the invention lacks the tongue-shaped nozzle lips required in the prior art for the shaping and alignment of the blowing air jet direction, which led to frictional contact with the material web.
  • the choice of the blowing angle makes it possible to determine whether the focus of the device should be more on conveying or more on suction. The larger the blowing angle, the larger the sector of the source flow, so that the suction forces increase and the delivery forces decrease. The maximum conveying effect is achieved when the blowing air jet direction runs parallel to the guide surface.
  • each nozzle has a plurality of nozzle openings, each with a tangential component of the blowing air jet direction, the tangential components of the blowing air jet directions of all nozzle openings being in the same direction.
  • a spiraling source flow is generated on the entire circumference of the conical depression.
  • the nozzle body is made of sheet metal and the nozzles are molded into the sheet.
  • the nozzle body is solid and the nozzles are formed in the nozzle body by machining.
  • each nozzle is formed by a shaped body which is used in the nozzle body, which is made in particular of sheet metal. This alternative is particularly suitable for large quantities.
  • the device according to the invention can be designed differently depending on the task. If it is only a question of guiding the material webs or sheets of material, the nozzle body can be designed as a blow strip with nozzles arranged in a row transverse to the guide direction. If the aim is to achieve a spreading effect at the same time, the blowing jet direction of the nozzles in the central section of the bar is essentially perpendicular to the longitudinal axis of the nozzle body and passes from this section in a graduated manner in a direction parallel to the ends. If a conveying effect is to be exerted on the material sheets, then the blowing jets of all nozzles are directed essentially in the conveying direction.
  • the intensity of the guidance or conveyance can be influenced by a more or less dense assembly of the nozzle body with nozzles.
  • the nozzle bodies can also be designed according to the air cushion principle.
  • An application according to the invention consists, for example, in that the nozzle body, as an arcuate deflecting body, has at least one row of nozzles arranged on each of its two edges running transversely to the conveying direction. If several rows are arranged on each edge, the nozzles of the two rows should be offset from one another.
  • the nozzle body can also be used in the case of a sheet deposit with a conveyor track arranged above a sheet stack, in particular with a slide bar arranged downstream of a cross cutter, for the overlap of the sheets to be deposited one after the other.
  • a nozzle body is used in which each nozzle has blow-out openings arranged symmetrically around the center.
  • a blast air-fed nozzle is formed in a solid nozzle body 1 with a flat side 2 facing a material web M to be conveyed and conveyed by machining.
  • the nozzle has a conical depression 3 and an eccentric nozzle opening 4 with a blowing jet direction S, which runs parallel to the adjacent guide surface 3a of the lateral surface 3b of the conical depression 3.
  • the blown air emerges in the form of a source flow with a sector angle ⁇ over the adjacent edge 5 of the conical depression and onto the material web M.
  • Figures 2.2a differs from that of Figures 1.1a only in that the nozzle body 1 is made of sheet metal and the nozzle is formed by deforming the sheet.
  • FIGS. 4,4a also differs from that of FIGS. 3,3a in that the upper region of the conical recess 3 has a larger opening angle than the lower region.
  • FIGS. 5.5a corresponds to that in FIGS. 3.3a with the difference that not one nozzle opening but three nozzle openings 4a, 4b, 4c are provided and the blowing air jet directions S a , S b , S c additionally have a tangential component, where the tangential components are in the same direction.
  • nozzle bodies corresponding to FIGS. 1 to 4a are designed as parallel strips.
  • Each bar 11, 12, 13 carries a row of nozzles, the resulting jet direction of which is aligned with the source flow.
  • ⁇ 90 °
  • K 25 mm
  • d 4 mm
  • t 50 mm
  • b 70 mm
  • c 30 mm if the nozzles with a
  • Blown air pressure of 1/100 bar can be operated.
  • nozzles according to one of the exemplary embodiments 1 to 4a are used.
  • the resulting blowing jet directions are not directed in the same direction, but are arranged essentially perpendicular to the strip axis in the region of the center of the strip and then gradually move towards the ends in a direction parallel to the axial direction of the strip.
  • a spreading effect is exerted on the material web.
  • the gradation of the direction down to parallel to the axial direction and to the ends is chosen because otherwise the additive lateral forces exerted by the individual nozzles in the middle would be too great.
  • the nozzle body extends perpendicular to the conveying direction and has two rows of nozzles corresponding to the exemplary embodiment on its two edges extending transversely to the conveying direction of Figure 1.1a, wherein the nozzles of adjacent rows are offset by half a pitch. Between the edges, the nozzle body has an arcuate deflecting body B.
  • the blowing air jet direction of the nozzles is at the two edges directed towards each other so that an air cushion carrying the material web M is built up between the edges in connection with the material web M to be guided.
  • the nozzles on one edge and the nozzles on the other edge are transverse to the conveying direction and open to the material web M channels N 1, N 2, which serve the Bernoulli effect of air flowing between the nozzles to counteract the small material web distance.
