Definitions

  • the invention relates to a stapling device for cross-stitching product parts, in particular in a folder arranged downstream of a rotary printing press, according to the preamble of claim 1.
  • DE 29 32 757 C2 describes a stapling device in a folder of a rotary printing press.
  • a combined cutting and stapling cylinder is provided with stapling dies and patrices.
  • the patrix is moved using a four-bar linkage.
  • a disadvantage of this stapling device is that the staple executes a relative movement in the circumferential direction with respect to collector and product parts during the stapling process. This can result in damage to the products and torn stapling.
  • the invention is based on the object / a stapler len of endeavortei to provide for cross-stitching in which a staple is no relative movement in the circumferential ri rect based on the running to be stapled product parts or on a counter-cylinder during a stapling operation.
  • This object is achieved by the features of the characterizing part of claim 1.
  • the advantages that can be achieved with the invention are, in particular, that relative movements of the clamps with respect to the product parts or the closing counter-bearing perpendicular to the stapling movement are largely avoided. This reduces bending stresses acting on brackets and eyes against bearings. This stapling movement produces a high staple quality, since tearing out the clip from the product parts is avoided. Thanks to the optimized stapling movement, it is possible to staple thicker product parts or more layers of product parts compared to the prior art, and to achieve higher production speeds. In addition, the load on the stapling device due to vibrations is reduced.
  • the stapling device according to the invention is shown in the drawing and will be described in more detail below.
  • Figure 1 is a schematic side view of a booklet device according to the invention.
  • Figure 2 is a schematic section of the booklet device according to the invention.
  • 3 shows an enlarged detail in a schematic representation of a movement sequence during a stapling operation corresponding to FIG. 1.
  • a cutting and stapling cylinder support 3 and a counter cylinder 4 acting collector Izy li nder 4 are rotatably supported about their parallel axes of rotation 6, 7.
  • the cutting and He tylinder support 3 is provided with two rotatable cutting cylinders 8, 9 as well as with two rotating stapling cylinders 11, 12, the axes of rotation 13, 14, 16, 17 of which are paired by 180 ° offset, concentrically in a radius r3, z.
  • B. r3 300 mm, to the axis of rotation 6 of the cutting and stitching cylinder support 3 are arranged.
  • the cutting and stapling cylinders 8, 9, 11, 12 are offset by 90 ° to one another.
  • the cutting and stapling cylinders 8, 9, 11, 12 rotate during a cutting or stapling process in the opposite direction to collecting Izyli nder 4.
  • the stapling cylinders 11, 12 have the same structure, which is why the following description is limited to a staple cylinder 11.
  • On the stitching cylinder 11 three lamella planes 21 are provided, each offset by 120 ° and extending parallel to its axes of rotation 16, in each of which several, in the present example two, stitching heads 22 are fastened in the axial direction.
  • Each stapling head 22 essentially consists of a stamp 23, which is fixed with respect to the stapling cylinder 11, 12, and a spring-loaded, radially movable stapling piston 24.
  • the stapling pistons 24 are provided with two cutting and guiding elements 26 at their outwardly facing end.
  • a camshaft 27 engages at an inward-facing end of the tacking piston 24. This camshaft 27 is mounted in the center of the stitching cylinder 11 and rotates at a speed n27, which corresponds exactly to the speed n3 or an integer multiple of the speed n3 of the cutting and stitching cylinder carrier 3.
  • the camshaft 27 is designed in such a way that the tacking piston 24 is extended during the takeover of the stitching wire and, after the stitching has been completed, that is to say in a center 28 of the cutting and tacking cylinder carrier 3 and collecting nozzle 4 is completely retracted.
  • An eccentric bending horn 29, for example, is arranged around the stapling cylinders 11, 12 in the interior of the cutting and stapling cylinder carrier 3 in the region of the stapling heads 22. A distance of the inner surface 31 of the bending horn 29 extending parallel to the axis of rotation 16 of the stitching cylinder 11 to the axis of rotation 16 of the stitching cylinder 11 decreases in the direction of rotation of the stapling cylinder 11, for. B.
  • the collector Izy l i nde r 4 serves as a counter cylinder for the
  • the bevels of the toothing of sun or planet gear 52, 51 of cutting cylinders 8, 9 are not equal to the bevel of the toothing of sun or planet gear 53, 54 of stitching cylinders 11, 12, causing a phase shift between cutting cylinder 8, 9 and stitching cylinder 11 , 12 can be performed.
  • the stitching can be adapted to a bottom or top fold.
  • n41 or n11
  • Staple wire feed device 56 is offset in the direction of rotation of the cutting and stapling cylinder carrier 3 by 144 ° to the central 28 of the cutting and stapling cylinder carrier 3 and collecting cylinder 4 on the periphery of the cutting and stapling cylinder carrier 3.
  • the next stapling head 22 has the greatest distance from the axis of rotation 6 of the cutting and stapling cylinder carrier 3, ie stapling head 22, axis of rotation 16, 17 of the stapling cylinder 11, 12 and axis of rotation 6 of the cutting and stapling cylinder carrier 3 are located on one common straight lines.
  • a U-shaped die is formed for bending the clamps.
  • a stitching wire becomes the cutting and guiding elements 26 of the stitching head 22, and then cut off by the progressive rotational movement of the cutting and stitching cylinder carrier 3.
  • the cut-off stitching wire is brought under the first spring plate 32, as seen in the direction of rotation, by the progressive rotational movement of the stitching cylinder 11, 12. The stitching wire is thus fixed in the cutting and guiding elements 26.
  • the stitching wire is guided into the area of the bending horn 29. Due to the reduced distance between the inner surface 31 of the bending horn 29 to the axis of rotation 16 of the stitching cylinder 11, the stitching wire is pressed into the U-shaped die formed by the punch 23 and cutting and guide elements 26 and thus during the rotational movement of the stitching cylinder 11 to one Bracket shaped.
  • the shape of the clip is completed at the latest before it exits the bending horn 29, in the present example after the stitching head 22 has rotated about 180 ° in the bending horn 29.
  • the high area of the camshaft 27 presses the stitching piston 24 with the cutting and Guide elements 26 to the outside.
  • the shaped clamp is then held by the second spring plate 33, which continues the bending horn 29 in the direction of rotation.
  • the camshaft 27 rotates from its high range to its low range with respect to the tacking piston 24.
  • the tacking piston 24 moves with the cutting and guiding elements 26 radially inwards and gives the clamp legs Partially free bracket.
  • the corresponding stapling heads 22 - and thus the staples - are positioned radially on the axis of rotation 7 of the collecting cylinder 4.
  • the entire stapling movement is determined by the superimposed rotary movements of the stapling cylinder 11, 12 and cutting and stapling cylinder carrier 3 executed radially with respect to the axis of rotation 7 of the collecting cylinder 4.
  • the clamp is pressed into the product parts 57 by the rotary movement of the cutting and stapling cylinder carrier 3 by the fixed stamps 23 acting on the back of the clamp.
  • the cutting and guiding elements 26 are completely retracted and the clip leaves the second spring plate 33.
