Definitions

  • the invention relates to a drawing-in means for drawing in a material web according to the preamble of claims 1 or 3.
  • Such feeding means are used in particular in web-fed rotary printing presses in order to pull the beginning of the web of the new paper web through the printing press after a roll change.
  • the paper web can be guided through the printing press along different paths in modern web-fed rotary printing presses, so that the drawing-in means must be reversed accordingly along different drawing-in paths. Due to the complex geometry of the necessary pull-in paths, for example in the area of turning bars, the pull-in means must be guided in three-dimensional guides running through the room.
  • DE 94 15 859 U1 discloses a pull-in means designed in the manner of a metal strip.
  • This metal strip can either be designed as an endless strip, which is guided over deflection rollers.
  • a metal strip section can be used, the two ends of which are each wound on a drivable winding roll.
  • DE 22 41 127 A1 discloses a pull-in means which is designed as a spring steel strip and is guided between two parallel tubes arranged at a short distance from one another. Functional surfaces are profiled into the spring steel strip, which engage in the recesses of a drive pulley, so that the drive force can be transmitted from the drive pulley to the pull-in means.
  • DE 44 09 693 C1 describes the use of a side arch chain as a pull-in means.
  • the rivet bolts of the side arc chain are conical, so that the side arc chain is axially movable in each chain link by a small area deviating from the direction of the longitudinal axis.
  • EP 0 418 903 A2 describes a paper web holding part which is fastened to the pull-in means by means of a flexible band. In addition to being fastened by means of the band, it can be secured to the pull-in means by means of a clip, for example when returning the pull-in means.
  • DE 100 24 013 C1 describes a pull-in chain on which a coupling element designed as a driver is detachably arranged.
  • the invention has for its object to provide a pull-in means for pulling a web of material.
  • An advantage that can be achieved with the invention is, in particular, that the optional equipping of the pull-in means with functional elements creates a flexible system that can be converted and adapted in a simple manner depending on the application and functional requirements.
  • the pull-in means designed as a metal strip section represents a base support element on which, depending on the application, the different configurations can be realized by fixing different functional elements. This is particularly advantageous if the material web that is drawn in is divided in the longitudinal direction during the drawing in and the partial webs that are created as a result are to be drawn in along different drawing paths.
  • the pull-in means can be equipped with a plurality of coupling elements, to each of which a partial web can be coupled. If a whole web of material is to be retracted at a later point in time, all but one of the coupling elements are removed from the infeed means.
  • the resulting feed system with various functional elements that can be combined to create the feed means that a wide variety of pulling tasks can be solved flexibly.
  • Figure 1 shows a first embodiment of a broken Einzugmitteis in top view.
  • FIG. 2 shows a metal strip section of a pull-in center according to FIG. 1;
  • Fig. 3 shows a second embodiment of a broken-in Einzugmitteis in top view
  • FIG. 4 shows a metal strip section of a feed means according to FIG. 3; 5 shows a cross section through the pull-in means according to FIG. 1 along the section line V - V;
  • FIG. 6 shows a cross section through the pull-in means according to FIG. 3 along the section line VI-VI;
  • FIG. 7 shows the pulling means guided in a guide according to FIG. 3 in cross section
  • FIG. 9 shows a cross-section of a transfer station of a third exemplary embodiment of a pull-in means.
  • the pull-in means 01 shown in FIGS. 1 and 5 essentially consists of a finite band section 02 which is largely dimensionally stable in its longitudinal direction, in particular a metal band section 02 (see FIG. 2) which is covered at least in sections with a plastic layer 03 ,
  • the metal strip section has e.g. B. a thickness d02 of a maximum of 0.3 mm, in particular a maximum of 0.2 mm. That means the z. B. made of spring steel metal band section 02 forms the core of the Einzugmitteis 01, in which tensile and shear forces can be transmitted, whereas the required functional surfaces of the Einzugmitteis 01 are realized by the coating 03 designed as a plastic layer 03 by means of appropriate shaping.
  • the plastic layer 03 represents, for example, individual carrier elements 03, e.g. B. plastic segments 03, to which functional elements described in more detail below can be releasably attached.
  • the plastic layer 03 is structured in sections. Sections alternate as functional surfaces 04, z. B. tooth flanks 04, in which a gear for driving the feed means 01 can engage, and sections with as functional surfaces 06, z. B. sliding elements 06, which can come to rest in a profile guide not shown here, in pairs in the longitudinal direction of the feed means 01.

  • guides 32, z. B. guide profiles 32 (Fig. 7) arranged.
  • Drive motors with gearwheels are provided at certain intervals along the guide profile 32, the distance between the gearwheels being chosen to be smaller than the length of the feed means 01, so that the feed means 01 can be transferred from one gearwheel to the next during the conveyance along the feed path. Due to the deformability of the pull-in means 01, complex guide geometries can be realized.
  • Clip structures 08 and 09 are formed on the coating 03 formed as a plastic layer 03 on the top and bottom of the metal strip section 02, each lying opposite the tooth flanks 04 and the sliding elements 06.
  • Various functional elements can be clipped into these clip structures 08 or 09 in a form-fitting manner, in order to equip the pull-in means 01 with the required functional elements in accordance with the respective intended use.
  • the pull-in means 01 shown in FIG. 1 is equipped with two functional elements 11, 12.
  • the first functional element 11 is designed in the manner of a coupling element 11, to which a material web 13 can be coupled, for example using a pull-in tip.
  • the functional element 12 is, for. B. formed as an initiator element 12 and can be evaluated contactless by a sensor.
  • the position of the pull-in tip in the printing press can be determined. If the pull-in means 01 is to be used for a different type of pull-in task, the functional elements 11, 12 can be removed in a simple manner and the pull-in means 01 can be equipped with other functional elements in sufficient numbers.

  • the annular recesses 14 are arranged in pairs in the area of the tooth flanks 04 or sliding elements 06 or the clip structures 08, 09, since in these areas the greatest forces have to be transferred from the plastic layer 03 to the metal strip section 02.
  • the recesses 16 are slit-shaped transversely to the longitudinal axis of the metal strip section 02, whereby the deformability and in particular the torsion of the metal strip section 02 is increased.
  • FIG. 3 and 6 to 8 illustrate a second exemplary embodiment of a pull-in means 20.
  • the core of the pull-in means 20 is in turn guided by a band section 21, e.g. B. metal strip section 21 (see FIG. 4), wherein the coating 22 formed as a plastic layer 22 is releasably connected to the metal strip section 21 in this embodiment.
