Definitions

  • the present invention relates to a device for stapling successive runs of a rotating conveying device, which are straddled, sheet-like printed products which are guided outside of a stapling head having at least an approximately circular and cooperating stapling head, each stapling head being stapled is driven in sync with the conditions.
  • Such a device is disclosed, inter alia, by CH-A-667 621.
  • the latter has a saddle stitcher in which the printed products are placed astride the collecting sections arranged symmetrically about an axis of rotation and are conveyed by carriers along the collecting sections to an effective area of a stapler.
  • the stapling heads of the stapler are assigned to the collection sections, so that everyone can join Print products fed to the collection section can be stapled at the end of the collection area, with staplers being used to carry out the stitching process, in which the stitching heads are coupled with the collecting sections and are actuated by stationary control cams, or in which the stitching heads extend over a part of the circumference of the through Collection sections formed drum-shaped collecting device are actuated driven.
  • FIG. 3 shows a construction according to which the stitching heads run on a circular movement path, that is to say as in the prior art mentioned above.
  • the circular trajectory concentrates or restricts the stitching area to a point on the circumference of the collecting drum.
  • the respective stitching head hardly comes into contact with the printing sheets placed on the synchronously driven supports during the rotary movement for setting the clamp, whereas in embodiments with staplers arranged along the circumference of the collecting drum, the stitching heads are arranged in a kidney-shaped or oval shape outside the collecting drum trained trajectories are positively guided so that the printed sheets are stapled on a section of the synchronous movement on which at least one stitching head remains for a short time.
  • DE - A - 21 16 734 has a machine for stapling a web of material guided vertically between two cylinders rotating at the same speed, one cylinder as a stapling cylinder with a stapling stamp arranged therein, - which takes a cut wire length from a cutting device and into one Bracket forms -, and the other cylinder is designed as a stapling organ with an anvil assigned to the stapling stamp.
  • the stapling stamp is arranged to be longitudinally displaceable in a guide piece and connected to a control device in such a way that the stapling stamp moves in parallel with the web of material and the anvil can be moved against the stapling stamp to close the clamp driven by the web of material. This means that the clamp is finally deformed at the closest point of proximity of both cylinders.
  • the object of the present invention is therefore to remedy the disadvantages mentioned and a device of the type mentioned To create a way with which the end product can be given high stability and quality by stapling the printed products.
  • this object can be achieved in that the orbits of the stitching head (s) and the supports in the area of greatest approximation have a common section on which the orbit of the stitching head (s) is controlled by movement control of the stitching head (s) parallel to the orbit the conditions are ongoing.
  • the common route section is arranged on an at least partially circular region of the orbit of the supports, so that a favorable drive principle for the supports can be selected.
  • the common route section is distributed on both sides of a plane that connects the axes of rotation of the at least partially circular orbits of the stitching head (s) and supports, so that an optimal interaction of the stitching head and the support or stitching is achieved.
  • the accuracy of the stapling can be favored if the stapling head (s) and / or the supports or the bending devices assigned to them are attached to driven hubs, because in this way the supports can be positioned precisely above the folders and relative to the stapling heads.
  • FIGURE shows a detail of the device according to the invention on a device 1, also called a saddle stitcher, intended for collecting and then stapling folded, arch-shaped printed products.
  • the printed products are fed in a manner not shown to a conveyor section 2, which is formed by a plurality of saddle-like supports 4 which extend at a distance from a traction device 3 and are attached at intervals and which serve to place the printed products astride. Investors are used for this.
  • One visible axis 6 belongs to a stitching wheel 7, while an invisible axis is provided as a deflection wheel of the conveyor device 8 forming the conveyor section 2.
  • the stapling wheel 7 has, at a distance from the supports 4 on the circumference, bending devices 9, each of which forms a stapling station in the vicinity of the stapler 5.
  • a bending device could alternatively be assigned to each support 4, which would involve a greater outlay.
  • the conveyor track 2 which rises after the loading, runs to the stitching wheel 7 in the stitching area. This is formed by the stitching wheel 7 and the stitching device 5 arranged above it. According to the drawing, this consists of twelve stitching heads 10, which are indicated by radial center lines, and form a common axis of rotation 11. However, it could be one or another number of stapling heads which the stapler 5 has. On the effective stapling circumference of the stapler on which the stapling heads 10 rotate, the distances between them are selected according to the spacing of the supports 4 on the conveying device 8 and the bending devices 9 on the stapling wheel 7.
  • the stapling wheel 7 and stapler 5 are advantageously drive-connected, so that there is a mutually coupled dependency.
  • the space requirement of the device according to the invention can be determined by the spacing of the supports 4 and the number of stapling heads 10 of the stapler 5.
  • a stapler 5 it is of course possible to use a stapler 5 the division of the stitching heads 10 on the circumference of rotation does not correspond to the distances between the conveyor 8, which would require special control of the stitching heads.
  • a wire dispensing device 12 is arranged, on which the stitching head 10 passing by takes over a wire section intended for a clip, which is preformed in the stitching area when it is taken over or further.
  • the stapler 5 is located outside the stapling wheel 7, the stapling heads 10 run approximately in a circle and are driven in the stapling area in the same direction with the supports 4.
  • the orbits formed by the rotation of the stitching heads 10 and the rotary movement of the supports 4 have a common route section in the area of greatest proximity, on which the stitching process is carried out. This is achieved by a special movement control of the stitching heads in the stitching area, so that the stitching head (s) are connected to the overlays for a longer period of time than when there is a selective encounter.
  • the stitching heads 10 move on the common route section B parallel to the orbit 13 of the supports 4.
  • the control path A used prevents abrupt deflections of the stitching heads.
  • a saddle stitcher with feed stations which are driven in the machine cycle and are assigned to several collecting sections with a saddle-shaped support for the printed products placed thereon, is of course also suitable for use of the device according to the invention, the collecting sections being arranged axially symmetrically and driven about an axis and acting along the supports to form a stapler Drivers are formed and the feed stations feed one of the collecting sections with a printed product in succession with each machine cycle.
  • this is distributed on both sides of a plane running through the axes of rotation 6 and 11 of the circular orbits 13, 14 of the stitching heads 10 and supports 4 and is equipped for gentle changes in direction.
  • Both the stitching heads 10 and the bending devices 9, respectively. the conditions for a saddle stitcher with a drum-like arrangement of the collecting sections are attached to a driven hub.
  • the distance between the supports 4 and the stitching heads 10 or their orbits can be adjusted 13, 14 can be adjusted.
