Definitions

  • the present invention relates to a stapler with a stapling cylinder carrying at least one stapling head according to the preamble of claim 1, 2 or 3.
  • Staplers of this type conventionally comprise a stapling cylinder with one or more stapling heads and a locking cylinder, each of which can be rotated about an axis of rotation and between them delimit a gap through which the printed products to be stapled, in particular in a web-fed rotary printing press, pass and are stapled, the Lock cylinder serves as an abutment for the stitching head.
  • the number of staples required to staple a printed product and their distance from one another depends on the length of the fold line along which the printed product is folded and stapled. Usually two or three brackets are used. If printed products with different dimensions are to be processed one after the other, a complicated adjustment of the stapling apparatus may be necessary when changing the product.
  • DE 38 10 457 A1 discloses a rotary stapling device whose stapling heads are axially displaceable.
  • the invention has for its object to provide a stapler with a stapling cylinder carrying at least one stapling head.
  • An important advantage of the stapler according to the invention is that it allows the position of the stapling heads to be quickly adapted to the dimensions of a printed product to be processed, without parts having to be removed and reassembled for this purpose. A simple displacement of the stitching heads enables quick adaptation to changing formats.
  • the locking cylinder cooperating with the stapling cylinder conventionally carries locking blocks which, on their side facing the stapling heads, have depressions for guiding the legs of a staple during stapling. These locking blocks are expediently displaceable together with the stitching heads.
  • two gears are preferably provided in each case for converting a rotary movement into a displacement of at least one of the stitching heads or at least one of the locking blocks, and the gears are coupled to one another in such a way that they drive movements of the stitching head and of the locking block in each case over the same distances.
  • a stitching wire supply device assigned to each stitching head is preferably also displaceable; their displacement can also be expediently driven by a gear mechanism which is coupled to that of the stitching head, so that the stitching head and the stitching wire supply device each move over the same distances.
  • a threaded spindle is preferably used to convert a rotation into a displacement of a stitching head, a locking block or a stitching wire supply device.
  • such a spindle is preferably held coaxially in the stitching device or locking cylinder.
  • the spindle is preferably via a differential with an actuating shaft and with the cylinder in which it is held connected, and the transmission ratio of the differential gear is selected so that the spindle and the cylinder rotate at the same speed when the adjusting shaft is stationary.
  • Fig. 1 is a partial perspective view of a stapler
  • Figure 2 is a schematic section through a cylinder of the stapler.
  • 3 and 4 are sections through modified configurations of the cylinder.
  • Fig. 1 is a perspective view of a stapler, wherein side frame plates, ar, on which the various cylinders of the stapler are mounted, and components which serve to feed the printed products to be stapled to the lock and cylinder are not shown for the sake of clarity.
  • the stapling cylinder 01 rotatably mounted in the side frame plates about an axis A carries Two schematically illustrated stapling heads 02, which grip, with each staple of the stapling cylinder 01, a piece of wire 04 provided on a stapling wire supply device 03 assigned to the stapling head 02, cut them off and bend them into a staple in order to then staple a printed product with the staple, the gap 06 passes between the stitching cylinder 01 and a locking cylinder 07.
  • Stapling cylinder 01 and lock cylinder 07 have at their axial ends two gear wheels 08 and 09, respectively, which have two intermediate gear wheels 10; 11 are coupled to each other.
  • a common drive motor not shown, engages one of the gears 08; 09; 10 or 11.
  • the number of teeth of the gears 08; 09; 10; 1 1 are chosen so that both cylinders 01; 07 Rotate at the same speed or the speed corresponding to the number of stapling heads.
  • a spindle 12 is arranged coaxially, which can only be seen in FIG. 1 on the stapling cylinder 01.
  • the two stitching heads 02 of the stitching cylinder 01 reach through a slot 13 in its hollow jacket and each have a bore with an internal thread in a section engaging in the jacket, which bores with the spindle 12.
  • the two stitching heads 02 are located at sections 12a; 12b (see FIG. 2) of the spindle 12, each with the opposite thread pitch, so that rotation of the spindle 12 with respect to the stitching cylinder 01 causes the same movement of the stitching heads 02 along the axis A.
  • the locking blocks 14 of the locking cylinder 07 are displaceable in the same way by means of the spindle 12 guided in the hollow interior thereof.
  • An actuating shaft 16 is axially guided out of the stapling cylinder 01 and the locking cylinder 07 and, as shown in FIG. 2, is coupled to the spindle 12 via a differential 17, namely a two-stage planetary gear 17.
  • the actuating shaft 16 and the spindle 12 are each connected to a sun gear 18 and 19 of a stage of the planetary gear 17, and a ring gear 21 is fixedly connected to the gear 08 and 09, respectively, via which the concerned Cylinder 01 is driven in rotation when the stapler is in operation.
  • Fig. 2 shows the gear 08 directly on the planetary gear 17; 1 are both at different ends of the stapling cylinder 01 and are coupled by its rigid jacket.
  • any other differential gear construction e.g. a harmonic drive gear is considered, provided that it is ensured that between the three connections of the gearbox such a transmission ratio applies that, when the adjusting shaft 16 is stationary, the cylinder 01 or 07 and the spindle 12 located therein rotate at the same rotational speed, so that in Do not operate the stitching heads 02 or closing blocks 14 along the axis A; D hike.
  • a servo drive (coupled or not coupled) is conceivable for each axis or a manual drive.
  • the adjusting shafts 16 of the stapling cylinder 01 and the locking cylinder 07 are coupled by a toothed belt 23 wrapped around two pinions 22.
  • the diameters of the pinions 22 are the same, so that the spindles 12 each move in the same way and drive congruent movements of the stitching heads 02 and the locking blocks 14.
  • the stitching wire supply devices 03 are held on two guide spindles 24, which are firmly connected to the side plates, and can be displaced parallel to the axis A.
  • the stitching wire supply devices 03 thus follow each adjustment of the stitching heads 02.
  • a single adjustment movement is sufficient to move the stitching heads 02, supply devices 03 and closing blocks 14 towards one another while maintaining their exact alignment move.
  • the coupling via toothed belt 23; 28 can also be replaced by a coupling via gears or the like, which ensures that the threaded spindles 12; 26 cover the same rotation distances.
  • FIG. 3 shows a modification of the section of FIG. 2, in which three stitching heads 02 are arranged on the stitching cylinder 01.
  • the threaded spindle 12 extends through all three stitching heads 02, but has no thread in its middle section, on which the middle stitching head 02 is arranged, and can therefore rotate freely without displacing the middle stitching head 0J. This is secured directly on the jacket of the stapling cylinder 01 against axial displacement.
  • the two side stitching heads 02 always keep the same distance from the middle stitching head 02.
  • Complementary to the third stitching head there is of course also a third locking block 14 on the locking cylinder 07 and a third stitching wire supply device 03, which are not specifically shown in a figure.
  • FIG. 4 has two threaded spindles 12, each of which only extends over half the length of the cylinder 01.
  • Each threaded spindle 12 carries a stitching head 02 and can be driven by a planetary gear 17 independently of the other. In this way, asymmetrical positions of the stitching heads 02 (or the closing blocks and the stitching wire supply devices 03) can also be set with respect to the central plane of the stitching apparatus.
