Definitions

  • the invention relates to a stapler with a stapling cylinder carrying at least one stapling head according to the preamble of claim 1 or 2.
  • Such staplers conventionally comprise a stapling cylinder which carries at least one stapling head and an independent closing cylinder, which can each be rotated about an axis of rotation and delimit a gap between them through which the printed products to be stapled pass and are stapled, the closing cylinder serving as an abutment for the stapling head serves.
  • 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 is that it enables secure stapling of printed products, in particular printed products produced in web-fed rotary printing presses, of different thicknesses.
  • By making the width of the gap traversed by the printed products adjustable it can be ensured that the stapling head only moves tangentially to the surface of the printed product to be stapled, so that there is no risk of contact traces remaining and also the synchronism of the stapler is not affected.
  • a first and a second distance are defined as a function of parameters of the print products to be processed.
  • a distance between the stitching head and the abutment is set by means of a motor.
  • the axis of rotation of this cylinder is held on two arms which are pivotable about a pivot axis parallel to the axis of rotation of the cylinder.
  • the suspension is preferably selected so that, in a typical operating position of the displaceable cylinder, the connecting line between the pivot axis and the displaceable rotation axis is parallel to the plane of the gap defined as the common tangent of the two cylinders in contact.
  • This attachment ensures that small deflections from this typical operating position run at right angles to the level of the gap, so that when the gap width is adjusted, it is ensured that the stitching head, when passing through the gap, faces the assigned abutment on the locking cylinder in the correct position.
  • the stitching cylinder and the locking cylinder are coupled by a gear and driven together.
  • This transmission has, according to a preferred, simple embodiment, a with the displaceable cylinder. B. by meshing in operative contact intermediate gear whose axis of rotation coincides with the pivot axis of the cylinder. The active contact between the displaceable cylinder and the intermediate wheel remains unchanged in any position of the displaceable cylinder.
  • the axis of the displaceable cylinder can also be held by a linear actuator.
  • this linear actuator should expediently move the displaceable cylinder in a direction perpendicular to the plane of the gap.
  • the locking cylinder can be provided as the only sliding cylinder. This is particularly expedient if the stapler is arranged as a largely autonomous device in a production line, since the locking cylinder, if it only has to serve as a support for the abutment, can be made smaller and lighter than the stapling cylinder.
  • Figure 1 is a partial perspective view of a first embodiment of a stapler.
  • FIG. 1A shows a modification of the embodiment from FIG. 1;
  • FIGS. 2-5 each show schematic side views of further configurations of the stapler.
  • Fig. 1 is a perspective view of a stapler, with 9.gesteilpiatten, on which the various cylinders of the stapler are mounted, as well as components that serve to supply the printed products to be stapled 01 and lock cylinder 04 are not shown for the sake of clarity.
  • the stapling cylinder 01 which is rotatably mounted in the sogesteilpiatten about an axis A, carries two schematically illustrated stapling heads 02 which, with each revolution of the stapling cylinder 01, grip a piece of wire presented on a dispenser (not shown), cut it off and bend it into a clamp, in order to subsequently use the clamp to produce a printed product to staple that passes through a gap 03 between the stapling cylinder 01 and a locking cylinder 04. More than two stitching heads 02 can also be arranged on the stitching cylinder 01.
  • Staple cylinder 01 and lock cylinder 04 are driven by a common motor, not shown. They carry at their axial ends two gears 06 and 07, each of which has two intermediate gears 08; 09 are coupled to each other.
  • the intermediate gear 08 is not shown on the side facing the viewer in FIG. 1.
  • the intermediate gears 08; 09 are about axes B; C rotatable.
  • the gear ratios of the gears 06; 07 are selected in such a way that stitching cylinder 01 and locking cylinder 04 rotate at the speed required for the translation.
  • the axis of rotation D of the locking cylinder 04 is suspended on two swivel arms 11.
  • the pivot arms 11 are in the region of their upper ends about the axis C of the
  • the displacement of the axis D is associated with a slight rotation of the locking cylinder 04 about its axis D when the stapling cylinder 01 is assumed to be stationary. That is, when the width of the gap 03 is adjusted by pivoting the arms 11, the position of abutments formed on the locking cylinder 04, which are intended to cooperate with the stitching heads 02 to close the clips, is shifted slightly in the circumferential direction.
  • the radius of the gear 07 In order to keep the displacement of the abutment as small as possible, the radius of the gear 07 must be as large as possible in comparison to that of the intermediate gear 09; a ratio of at least 2: 1 is desirable.
  • a compensation gear 21 which meshes with a fixed on the side frame plate 22, the gear ratio of the compensation gear 21 to the jacket / body of the lock cylinder 04 is selected so that it maintains its orientation when the swivel arms 11 are adjusted.
  • the intermediate gears 08; 09 replaced by a toothed belt 23, which with the gears 06; 07 of the stitching cylinder 01 and the locking cylinder 04 combs.
  • the adjustable suspension of the locking cylinder 04 on swivel arms 11 driven by an eccentric pin 13 is the same as in the case of FIG. 1.
  • the toothed belt 23 is guided around a resiliently mounted belt tensioner 24 so that the tension of the toothed belt 23 is independent of the position of the swivel arms 11 maintain.
  • stapling cylinders 01 and locking cylinders 04 are again connected via intermediate gears 08; 09 coupled together.
  • the axis of the locking cylinder 04 is suspended in two sliding blocks 26, each of which can be displaced in sliding rails 27 mounted on the side panels with the aid of a threaded rod 28 driven by a motor (not shown) and engaging in an internal thread of the sliding block 26. Since the amplitude of the displacement of the locking cylinder 04 is small in practice compared to the radii of the gears 07; 09 is, the engagement between the two is not lost when the locking cylinder 04 is displaced.
  • the slide rails 27 are oriented horizontally, so that the locking cylinder 04 does not have to be raised when the width of the gap 03 is adjusted.
  • FIG. 4 is derived from that of FIG. 3 in that the two
  • FIG. 5 shows, as a fifth embodiment of the invention, a stapling device integrated in a folder in a schematic side view analogous to that of FIGS. 2 to 4.
  • the stitching cylinder 31 is displaceably mounted, and the locking cylinder 32, which is also the collecting cylinder 32 of the folder, has a fixed axis.
  • the stitching cylinder 31 is held in a rigid frame which is formed by two end plates 33 rigidly connected by cross struts 34. This frame is suspended on a carriage 37 so as to be pivotable about an axis 36.
  • This carriage 37 is horizontally displaceable as required in order to open the gap 41 between the stitching cylinder 31 and the locking cylinder 32 for maintenance purposes.
  • a motor 38 mounted on the slide 37 drives two eccentric disks 39 which are connected to one another on an axis and on which the two end plates 33 each rest. Depending on the rotational position of the eccentric discs 39, the width of the gap 41 varies between the two cylinders 31; 32nd
  • the motor 17 or 38 regulating the gap width can be controlled from a control room. This calculates the required gap width and the required position of the eccentric pins 13 or eccentric discs 39 on the basis of data such as the number of pages of the products to be stapled, the thickness of the paper used, etc., which are already available at the control room in connection with other control tasks of other parts of a printing press in which the stapler is integrated. Manual adjustment of the gap width is therefore not necessary, and the work required for this is eliminated.
