Definitions

  • the present invention relates to a device for stapling successive runs of a rotating conveyor device straddlingly placed sheet-like printed products which are guided outside by a stapler having at least one circularly circulating and interacting with the runs head, each stapling head during stapling 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 printing products are placed astride the collecting sections arranged symmetrically about an axis of rotation and fed by carriers along the collecting sections to an effective area of a stapler become.
  • the stapling heads of the stapling machine are assigned to the collecting sections, so that everyone can join them
  • the printing section fed to the printed products can be stapled at the end of the collecting area, with staplers being used for carrying out the stitching process, in which the stitching heads are coupled with the collecting sections and are actuated by stationary control cams or where the stitching heads are used over a partial area of the circumference of the Drum-shaped collecting device formed by the collecting sections are actuatably driven.
  • CH-A-667 621 mediates the classic stitching apparatus in which the axis of rotation of the stitching heads is spaced apart or is provided outside the collecting sections arranged in the form of a drum.
  • FIG. 3 shows a construction according to which the stitching heads rotate on a circular movement path, that is to say as in the aforementioned prior art.
  • the circularly designed movement path 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 co-rotating supports during the rotary movement for setting the staple, whereas, when arranged along the circumference of the collecting drum, the stitching heads are arranged in a kidney or oval shape outside the collecting drum trained trajectories are positively guided, so that the printed sheets are stapled on a section of the synchronization, on which a 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 element with an anvil assigned to the stapling stamp.
  • the stitching stamp is arranged to be longitudinally displaceable in a guide piece and is connected to a control device in such a way that the stitching stamp moves in parallel with the fabric web and the A-boss can be displaced against the stitching stamp to close the clamp driven by the fabric web . This means that the clamp is finally deformed at the closest approach point of both cylinders.
  • the deflection of the fabric web also has a disadvantageous effect on the stability of the stapled product.
  • the object of the present invention is therefore to remedy the disadvantages mentioned and to implement a device of the type mentioned at the beginning. to create the kind 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 have a common route section in the area of greatest approximation.
  • the supports on the common route section are adapted to the orbit of the stapling head (s), they can be designed so that they can be lowered.
  • the supports are preferably controlled at least on the common route section of the orbits with a control Device connected.
  • 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 arranged distributed on both sides of a plane connecting the axes of rotation of the at least partially circular orbits of the stitching heads and overlays, so that an optimal interaction of the stitching head and overlay or stitching is achieved.
  • the accuracy of the stitching can be favored if the stitching head (s) and / or the supports are fastened to driven hubs or the supports are positively connected to hubs, because in this way an exact positioning of the supports over the benders and against the stitching heads can be done.
  • the invention is then described with reference to an embodiment shown in the drawing.
  • the single figure shows a section of the device according to the invention on a device 1, also called a saddle stitcher, intended for collecting and then stapling folded, sheet-shaped printed products.
  • the printed products are supplied in a manner not shown in detail 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 extend at intervals, which serve to place the printed products astride. Investors are used for this.
  • 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 extend at intervals, which serve to place the printed products astride. Investors are used for this.
  • Stapling device 5 which is traversed by the traction device 3, which rotates endlessly around two axes.
  • the one visible axis 6 belongs to a stitching wheel 7, while an invisible axis is provided as the deflection wheel of the conveyor device 8 forming the conveyor section 2.
  • the conveyor device 8 which is approximately belt-like in the transverse direction, runs over the stitching wheel 7 and the deflection wheel, both wheels being mounted on the axles in duplicate.
  • the stapling wheel 7 has, at a distance from the supports 4 on the circumference, bending devices 9 which each form 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 11 and form a common axis of rotation 11. However, it could be one or another number of stapling heads which the stapler 5 has.
  • the distances between them are selected in accordance with the spacing of the supports 4 on the conveyor 8 or the bending devices 9 on the stapling wheel 7.
  • 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 and the number of stapling heads 10 of the stapler 5.
  • a wire dispensing device 12 On the length of the orbit of the stapling heads 10, outside the stapling area, a wire dispensing device 12 is arranged, on which the passing stapling head 10 takes over a wire section intended for a staple, which is preformed in the stapling area when it is taken over or further.
  • the stapler 5 is located outside the stapling wheel 7, the stapling heads 10 rotate approximately in a circle and are driven in the stapling area with the supports 4 running in the same direction.
  • the orbits formed by the rotation of the stitching heads 10 and the rotational movement of the supports 4 have, in the area of greatest proximity, a common section of the route on which the stitching process is carried out. This is achieved by a special movement control of the stitching heads or pads in the stitching area, so that the stitching head (s) are connected to the pads over a longer period of time than if they were encountered at one point.
  • the stitching heads 10 move on the common route section B parallel to the orbit 13 of the pads.
  • the control path A used prevents abrupt deflections of the stitching heads.
  • An embodiment variant is conveyed by the control path C and the common route section D, according to which the circulating path 14 of the supports 4 runs approximately parallel to the circulating path 14 of the stitching heads 10 in the greatest vicinity of the stitching wheel 7 and stitching device 5.
  • the supports 4 can be lowered in the area of the stapling, for which purpose a control (not shown) can be used.
  • a control (not shown) can be used.
  • the control of the stitching heads and supports by rollers on sta- tional or moving curves, gears etc. are known and therefore need not be discussed in detail here.
  • the common route section of the orbits 13, 14 is arranged on part of the circular path of the supports 4, which is incomplete due to the special design of the saddle stitcher.
  • a saddle stitcher with lay-on 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, are also suitable for use of the device according to the invention, the axially symmetrically arranged and driven around an axis with longitudinal sections of the supports are designed to be effective carriers and the loading stations successively feed one of the collecting sections with a printing product with each machine cycle.
