Definitions

  • the invention relates to a device for changing the conveying direction of bendable paper products or the like, which are brought up in a product stream, in particular scale-like at least two layers of paper products lying on top of one another, with a turning device which deflects angularly in a positive guide in the form of a screw thread.
  • a turning device which deflects angularly in a positive guide in the form of a screw thread.
  • Such a device has become known from DE-B-2 529 103.
  • Reversible conveyor known in which the isolated paper products are advanced by holders on a chain drive and conveyed away in any other direction.
  • the present invention has for its object to provide a way to redirect the formation of the paper products unchanged in another direction and, if necessary, to turn the individual paper products.
  • the device which may be in the form of an independent unit, can either replace deflection devices of known type in existing systems or can also be used for a new installation, e.g. a rotary cutting system.
  • the guide consists of a bead, a correspondingly curved rail, bar or the like. or has the latter and the conveyor belt runs parallel to the guide.
  • the guide can consist of separate, helical rollers, rollers or the like protruding from a stationary cylinder with their axes. consist.
  • At least one conveyor belt on its side facing away from the product with projections, lateral borders or the like.
  • the conveyor belt guide designed accordingly and at least one conveyor belt designed as an endless conveyor.
  • the cylinder preferably has holes for the rotatable reception of holders for the rollers or the like or the like. on.
  • the conveyor belt, the rollers, rollers or the bead can be a maximum of 15 cm wide; there can be lateral strips, guides or the like in a feed conveyor upstream of the turner. be provided for the product stream.
  • the angle of the helical guide between the feed and discharge conveyor is expediently twice as large as the angle between the longitudinal axis of the cylinder and the feeder.
  • the device according to the invention can also be supplemented in such a way that a reverser with a formation-fixed clamping of the product stream is connected downstream of the turner.
  • the user can have two conveyor belts running parallel at least in the area of contact with the product stream.
  • the paper products are largely held in a stable or formation-stable manner, so that the paper products leaving the re-user take exactly the same position in relation to their position and the respective distance to the neighboring paper products as in front of the feed conveyor.
  • At least one conveyor belt and / or the guide consisting of rollers or rollers or having this can be driven.
  • the return device is designed as an overhead conveyor.
  • the return conveyor can be arranged above the turner. In this way, not only is a particularly space-saving device obtained, but it is also possible to manufacture the turner in a modular manner and to connect the return device, which is likewise designed as an automatic module, to this module.
  • a turning device 2 is arranged after a feed conveyor 1, followed by the return device 3 and the removal conveyor 4.
  • the isolated paper product 5 shown in the exemplary embodiment is shown as a once-folded double page and is brought up in the direction of the arrow 6 and conveyed away in the direction of the arrow 7.
  • the intermediate turning and turning back of the paper product is described in more detail below; however, the paper product takes on exactly the same position in relation to the conveying direction and the neighboring paper products - be it isolated or in the form of scales - as in the feed conveyor after leaving the removal conveyor.
  • the feed conveyor 1 consists, for example, of two rollers 10, 11 which are connected to one another by four endless conveyor belts 12, 13, 14 and 15. Any side guides, strips or the like that are set to the width of the delivered paper products. are not shown.
  • the axis 16 of the turning device or the turning device 16 ′ runs at an angle of 45 ° to the feed conveyor axis.
  • the turner 16 ' consists of a cylinder which is firmly connected to the frame of the module and on which the rollers 20 shown in more detail in FIG. 4 are arranged.
  • a total of eight rollers 20 are provided, which are distributed in a cylindrical shape by 180 degrees of arc angle with respect to the turning axis 16 of the turning device 16 '. While the axis of the first roller 20 runs perpendicular to the feed direction 6, the axis of the eighth feed roller 20 runs perpendicular to the discharge axis 7.
  • the first roller 20 lies on the side of the turner 16 ′ facing the viewer, while the last roller 20 is arranged on the opposite side.
  • the intermediate six rollers 20 are distributed over the circumference of the cylinder 16 so that they create a helical connection between the first and last roller.
  • the rollers 20 are designed to run freely and are rotatably mounted in U-shaped holders 21.
  • the U-shaped holders each have a pin-shaped extension 22, which are each held in a corresponding hole 23 in the cylindrical turner 16 'by a locking screw 24; the locking screw 24 enables the holder 21 to be rotated in order to adapt it to the required guidance of a conveyor belt in the form of a screw thread.
  • the screw thread shape is indicated in Fig.
  • the paper product delivered by the feed conveyor is held in the area of the turning device 2 between two parallel conveyor belts in the width of the rollers 20, so that the individual paper products can be turned without changing their formation or their position and can be conveyed away in the direction of arrow 30; they can then be turned back by overhead conveying, as described in more detail below, and then, if necessary, fed to another treatment station in the direction of arrow 7.
  • the turning device is used by the positive guidance between the two conveyor belts, which are both driven synchronously, so that the individual products or the scale formation is turned by 180 ° , the individual products lying at the height of arrow 30 with their top down.
  • the eight rollers provided, for example, therefore not only deflect the product flow by 90 ° , but also turn the individual products by 180 ° , so that the underside of the paper products can be treated in an approximately immediately downstream treatment station, for example by applying adhesive , sticking labels or the like, or any overprint on the back is made possible.
  • the two belts run from the first roller 20 together helically to the last roller 20 one above the other, the upper belt 32 being driven by a driven roller 30 above the lower conveyor belt 33 to be described later and the eight rollers 20 runs to rollers 30 ', 30 ", the strip area on this side of the turner 16' being shown in a plan view with dashed lines and the area running over the rollers 20 being indicated by dash-dotted lines.
  • the lower conveyor belt 33 runs from the roller 34 directly over the rollers 20 (dash-dotted) to the reversing roller 31 and back to the roller 34.
  • the two conveyor belts in the area of the rollers 20 are guided directly one above the other, but are so elastic that they adapt to a certain degree to the thickness of the paper products being conveyed - be they single-layer or multi-layer.
  • the return conveyor 3 shown schematically in mirror-image representation in longitudinal section in FIG. 5, has four conveyor belts 40, 41, 42 and 43 which rotate as endless conveyors around the rollers 44 and 45, respectively.
  • the turning axis 16 would have to be changed by 90 ° in adaptation to the return conveyor 3 according to FIG. 5, the arrow direction 30 also correspondingly running in reverse in order to do justice to the cut of the return conveyor according to FIG. 5.
  • the roller 44 is on the right outside and is arranged higher than the roller 45, in the embodiment according to FIG. 5 it is reversed (in mirror image representation).
  • two parallel conveyor belts 50, 51 are provided, the upper conveyor belt 50 being guided around a deflecting roller 52, an outer upper roller 53 and a lower roller 54, and the roller 44.
  • the upper conveyor belt with the corresponding lower conveyor belt runs around the rollers 55, 56, 57, 58 and 59 and then back again to the deflection roller 52.
  • the lower conveyor belt 51 also runs, and in this case directly, on the rollers 55 to 59, the roller 55 being designed as a reversing roller.
  • the conveyor belt 51 then runs over the further reversing roller 60 to the roller 61 and to the driven reversing roller 62.
  • the two conveyor belts can consist of individual narrow conveyor belt strips; the conveyor belt strips - e.g. five in number - would have to be arranged so that they run in pairs in the area of the clamping of the individual products.
  • the return conveyor can be designed as an independent module or as an independent unit and can be used together with the turning device described above.
  • the individual products are fed in the direction of arrow 70 and conveyed away in the direction of arrow 71.
  • the arrow direction 30 corresponds to the arrow 70 in FIG. 5, while the arrow 71 should run in the opposite direction.
  • the deflecting rollers 44 and 52 to 60 would not have to be arranged on the left, as shown in FIG. 5, but on the right side of the drawing, i.e. above the conveyor belts 40 to 43. Because the removal, as shown in FIG. 1, would take place in the direction 7, the latter runs above the turner 16 or 16 'and is thus accommodated in a space-saving manner.
  • the helical positive guidance - in the embodiment shown, the rollers and the two conveyor belts are distributed over an arc angle of 180 ° in the turning area, which corresponds to a turning of the individual products from the top to the bottom.
  • more rollers can be provided and the turn of the products can be made larger or smaller by changing the arc angle of the positive guide.
  • the angle which the turning axis 16 forms with the feed conveyor or the feed direction 6 can be variable, as a result of which the corresponding discharge direction is changed.
