Definitions

  • the invention relates to a rail switch for a device for transporting
  • a partial web that has already been cut lengthwise can be fed to a double cross cutter for further processing of the individual partial webs, i.e. the partial webs are each fed (preferably at different heights) to a specific cutting device of the double cross cutter.
  • Known railway switches have a plurality of “paddles” for this purpose, which can be pivoted about an axis lying transversely to the conveying direction and essentially in the conveying plane.
  • paddles for example, 10 to 15 such paddles are arranged next to one another, so that the one to be transported
  • Material at the outer free end of the paddle can be fed to further processing at different heights. Due to the presence of several such paddles, flexible feeding is also possible side by side transported webs or sheets to other facilities possible. As a rule, a plurality of paddles are always pivoted together into a predetermined angular position, the width of the paddles (transverse to the transport direction) being selected to be significantly smaller than the smallest width of the web or sheet to be transported. This results in sufficient flexibility in the choice of the width of the individual partial webs.
  • the paddles of known railway switches consist of a profile which is U-shaped in cross section, the two legs of the U being relatively short and only serving to stiffen the paddle.
  • the width of the paddles and thus the profile is approx. 10 to 15 cm.
  • the top of the paddles, on which the web to be transported or the sheets to be transported rest with their underside, is flat.
  • the invention is therefore based on the object of creating a rail switch for a device for transporting material webs or sheet-like material, in particular for a corrugated cardboard system, which avoids the aforementioned disadvantages and in particular a contamination-free and exact transport of the material to be conveyed, also with light qualities and / or high speeds. Furthermore, the invention has for its object to provide a device for transporting material webs or sheet-like material, in particular for a corrugated cardboard system, in which contamination-free and safe transport is ensured over the entire length of the support surface for the material to be conveyed.
  • each pivotable paddle from one or more longitudinal bars with a convex cross-section in the direction of the underside of the material to be transported and by providing a sufficient air gap or distance between the individual longitudinal bars Formation of an air film and thus the floating of the material to be transported safely avoided.
  • the longitudinal rods of the paddles are cylindrical, in particular as tubes, each paddle or
  • Element consists of two longitudinal bars.
  • the longitudinal rods preferably have a diameter of approximately 3 to 4 cm, with a spacing of approximately 1 to 3 cm.
  • the longitudinal bars of each element are connected by webs which do not extend to the underside of the material web to be transported.
  • these webs can act as air guide elements which have a guide surface which form an obtuse angle with the underside of the material to be transported.
  • the guide surface is provided on the rear side of the air guide element, i.e. on the side facing the transport direction.
  • this measure can be used not only in connection with a track switch, but also with known support tables for transport devices for material webs or sheet material. the.
  • the longitudinal bars of each paddle can (optionally additionally) be connected at one or both ends of the longitudinal bars with transverse struts arranged thereon, the upper side of the transverse strut ending below the underside of the material to be transported.
  • the cross strut provided there at the rear end of the paddle can serve as a holder for the required pivot bearing.
  • FIG. 1 shows a section of a corrugated cardboard plant with several devices for the transport of material webs or sheet-like material
  • FIG. 2 is a schematic side view of a rail switch according to the invention
  • Fig. 3 is a plan view of the rail switch in Fig. 2 and
  • FIG. 4 is an enlarged side view of a section along the line II-II in FIG. 3.
  • the section of a corrugated cardboard system 1 shown in FIG. 1 consists of a short cross cutter 3 arranged from the feed end, which cuts an endless corrugated cardboard web 9 fed from the outlet of the heating and cooling section (not shown) on the lateral edges to produce format changes.
  • a first conveyor device 5 is provided, which essentially consists of a rigid table 7. This section of the conveyor 5 serves for further cooling of the still endless corrugated cardboard web 9 before it is fed to a cutting and creasing machine 11 at the output end of the first conveyor 5.
  • the partial webs 9a, 9b are fed to a web switch 13 at the output-side end of the cutting and creasing machine 11.
  • the web switch 13 feeds a partial web 9a to an upper support table 15 of a second conveyor device 17 provided below and the other partial web 9b to a lower support table 19 of the conveyor device 17.
  • the individual partial webs are then fed to a double cross cutter 21 which consists of the individual ones Partial webs 9a, 9b cut out sheets of the desired length.
  • the support tables 7 and 15 and 19 of the first and second conveyor devices 5 and 17 can be designed in a manner known per se as tubular tables.
  • the contact surfaces consist of a plurality of tubes arranged next to one another in a plane at a predetermined distance. This substantially prevents condensate, which escapes from the lateral edges of the corrugated cardboard, in the support surface for the underside of the corrugated cardboard web 9, since the corrugated cardboard web ideally has only one line contact with each tube of the supports. Due to the slope in the pipe cross section to the left or right of the line contact of the pipes, the condensate can flow down or is only reflected in those areas that do not come into contact with the underside of the web 9.
  • such tube tables can also reliably avoid the floating of the corrugated cardboard web at high transport speeds and / or light qualities.
  • the individual longitudinal bars can also be designed in any other way. It is only a requirement that the upper side facing the underside of the corrugated cardboard web to be transported is convex in cross section in the direction of the corrugated cardboard web. According to the invention, all the track switches 13 are also formed from individual longitudinal bars or elements in the manner explained below. 8th
  • FIG. 2 shows a side view of such a railway switch, designated by reference number 13 in FIG. 1.
  • the track switch 13 comprises, as can be seen from the plan view in FIG. 3, a plurality of pivotably mounted elements 23.
  • the elements or paddles 23 are pivotably supported about an axis A at the rear end of the paddle 23, the axis A being transverse to the transport direction I the
  • Corrugated cardboard web 9 and in a plane parallel to the corrugated cardboard web 9 (before the web switch 13 is fed) is stored.
  • each element 23 consists of two longitudinal bars 25 which are connected by means of webs 27.
  • the webs 27 are preferably designed such that their upper side does not protrude beyond the upper side of the longitudinal bars 25 or extend into the plane of the upper side of the longitudinal bars 25. This prevents the top of the longitudinal rods 27 from touching the underside of the corrugated cardboard web 9 to be transported.
  • the webs 27 between the longitudinal bars 25 can also take over the function of air guiding elements.
  • the webs 27 are designed in such a way that they have an air guide surface 27a, which is formed at the rear end of the web 27.
  • the air guide surface 27a forms an obtuse angle ⁇ with the underside of the material to be transported.
  • the air entrained by the underside of the material web 9 to be transported is deflected obliquely downward without an air build-up forming under the corrugated cardboard web 9 in areas in front of the webs 27.
  • the downward directed airflow generated in this way also creates a suction effect which holds the corrugated cardboard web securely on the surface of the elements 23.
  • Such webs 27 can be arranged at suitable intervals in the longitudinal direction of the element.
  • elements 23 may be provided.
  • This feature of the webs designed as an air-guiding element does not necessarily have to be used in connection with the rail switches according to the invention, but can also be used separately for rigid support surfaces.
  • a strut 29 which is directed essentially at right angles downwards and which is preferably fastened to the front of a web 27.
  • the underside of the strut 29 is articulated to the piston 31 of a hydraulic or pneumatic cylinder 33.
  • each element 23 can be pivoted about the axis A independently of the other elements.
  • the articulated connection of the elements 23 with the preceding rigid support can, as can be seen from FIG. 3, take place in such a way that a fork-shaped element 35 arranged on the rear side of a web 27 interacts with a strut 37 which is stationary on the upstream rigid support is attached, preferably also to a corresponding web.
  • these two elements can then be connected in the usual way by means of a bolt in the axis A.
