Definitions

  • the invention relates to a device for stapling signatures, 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 four-bar linkage does not produce a uniform movement and the stapling cylinder can therefore be excited to cause harmful vibrations.
  • the invention has for its object to provide a device for stapling signatures.
  • the advantages which can be achieved with the invention consist in particular in that only rotating parts are used which enable the stapling cylinder to be operated with little vibration.
  • the stapling device according to the invention does not require any installation space outside a stapling cylinder carrier and is also very compact.
  • the stapling device according to the invention is shown in the drawing and is described in more detail below.
  • a cutting and stapling cylinder carrier 3 and a collecting cylinder 4 acting as a counter cylinder 4 are around them parallel axes of rotation 6, 7 rotatably supported.
  • the cutting and stapling cylinder carrier 3 is provided with two rotatable cutting cylinders 8, 9 as well as with two rotatable stapling cylinders 11, 12, the axes of rotation 13, 14, 16, 17 of which are offset in pairs by 180 ° , concentric 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 counter to the collecting cylinder 4 during a cutting or stapling process.
  • the stapling cylinders 11, 12 have the same structure, which is why the following description is limited to a stapling cylinder 11.
  • Provided on the stapling cylinder 11 are three clamp planes 21, each offset by 120 ° and extending parallel to its axes of rotation 16, in which several, in the present example two, stapling heads 22 are fastened in the axial direction.
  • Each stitching head 22 essentially consists of a stamp which is stationary with respect to the stitching cylinder 11, 12 23 and a sprung, radially movable tacking piston 24.
  • the tacking 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 stitching of the stitching wire and, after the stitching has been completed, that is, in a center 28 of the cutting and stitching cylinder carrier 3 and collecting cylinder 4, is completely retracted.
  • An eccentric bending horn 29, for example, is arranged around the stitching cylinders 11, 12 in the interior of the cutting and stitching cylinder carrier 3 in the area of the stitching heads 22. A distance between 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 is reduced in the direction of rotation of the stitching cylinder 11, for. B.
  • the collecting cylinder 4 serves as a counter-cylinder for the cutting and stapling cylinders 8, 9, 11, 12 and is therefore provided with cutting strips 34 fixed to the cylinder and counterbearing 36 fixed against the cylinder.
  • the cutting cylinders 8, 9 and stitching cylinders 11, 12 are driven by means of a planetary gear transmission from a main drive gear train.
  • a planet gear 48 meshes with a number of teeth z48, z. B.
  • the bevels of the toothing of sun or planet gear 52, 51 of cutting cylinders 8, 9 are not equal to the inclination of the toothing of sun or planet gear 53, 54 of stitching cylinders 11, 12, which causes 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.
  • or n11
  • a staple wire feed device 56 is offset in the direction of rotation of the cutting and stapling cylinder carrier 3 by 144 ° to the center 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 stitching head 22 has the greatest distance from the axis of rotation 6 of the cutting and stitching cylinder support 3, ie stitching head 22, axis of rotation 16, 17 of the stitching cylinder 11, 12 and axis of rotation 6 of the cutting and stitching cylinder support 3 are located on one common straight lines.
  • a U-shaped die is formed for bending the clamps.
  • a stitching wire is fed to 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 - 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 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 staple piston 24 moves with the cutting and guiding elements 26 radially inward and partially releases the clip legs of the clip.
  • the corresponding stitching heads 22 - and thus also the clips - stand radially on the axis of rotation 7 of the collecting cylinder 4 shortly before the clip legs hit the product parts 57.
  • the entire stitching movement is caused by the superimposed rotary movements of the stitching cylinder 11, 12 and the cutting and stitching cylinder carrier 3 executed radially with respect to the axis of rotation 7 of the collecting cylinder 4.
  • the clamp is driven by the rotary motion of the cutting and Stapling cylinder carrier 3 is pressed into the product parts 57 by the fixed stamps 23 acting on the back of the clamp.
  • the cutting and guiding elements 26 are withdrawn completely and the clip leaves the second spring plate 33.
  • the clip penetrates the product parts 57 and is replaced by the z.
  • the stapling cylinders 11, 12 and thus the stapling heads 22 rotate about their respective axes of rotation 16, 17.
  • This rotational movement is carried out by means of the drive described in such a way that the stapling head 22 involved in the current stapling process at least from the beginning to the end of the stapling process , d. H. from hitting the product parts 57 to lifting off the product parts 57, executes an approximately radial movement aligned with the axis of rotation 7 of the collecting cylinder 4.
  • Both the relevant stitching heads 22 and the corresponding closing counter-bearings 36 move at approximately web speed.
  • the stapling cylinder 11 can of course also be stored separately from the cutting cylinders 8, 9 in its own rotating stapling cylinder carrier.
  • the device according to the invention is not limited to the exemplary embodiment shown with three-part collecting cylinder 4, but can also be adapted to other cutting and stapling devices with, for example, five- or seven-part collecting cylinder.
