Definitions

  • the invention relates to a longitudinal folding device with at least one former, according to the preamble of claim 1.
  • Folding formers are known to be used in folders for the production of longitudinal folds in a material web drawn over them. Certain types of products which are to be produced in cooperation with downstream transverse or longitudinal folding devices of a folding apparatus require a displacement of the former or, in the case of several, of one of the former in the longitudinal direction of the incoming material web.
  • the folder In the folders known from ROTOMAN printing presses from MAN - ROLAND Druckmaschinen Aktiengesellschaft, Offenbach, the folder is horizontally displaced in order to achieve the desired offset of the former nose.
  • the hopper inlet roller upstream of the folding former must also be displaced horizontally by the same amount, which also results in a change in the wrap angle and thus in the draft conditions. Since the hopper inlet roller is switched on in the drive train, its displacement can only be accomplished with considerable design effort.
  • a separate hopper feed roller is also necessary when one of several formers is moved.
  • the object of the invention is to achieve a displacement of a former with simple constructional means in a generic longitudinal folding device.
  • the folding former is arranged to be adjustable in the direction of the former inclination.
  • 1 denotes a former feed roller and 2 denotes a folding former that is displaceable relative to the former in the direction of its inclination angle.
  • the longitudinal folding device comprises a folding former 2, which is arranged downstream of a funnel inlet roller 1 which is fixedly mounted in frame side walls (12, 13) in the direction of movement of the material web.
  • This former is arranged in a frame 5 formed from side walls 3 and cross members 4.
  • the folding former 2 is held on its underside not far from the former nose 2a by means of a known and therefore not described in detail device 6 for fine adjustment of the former inclination, which is arranged axially adjustable in bearing blocks 7 connected to the frame 5.
  • the former 2 In its upper part, the former 2 is rotatably supported on its rear side via a linkage 8 and a tube 9 attached to it on an axis 10 installed transversely in the frame 5.
  • the units also involved in the longitudinal folding process, such as funnel outlet rollers 11 and possibly existing perforating devices, not shown in the drawing, are also arranged in frame 5.
  • the frame 5 is in turn mounted in the frame side walls 12, 13 of the folder in such a way that it can be displaced relative to the latter in the direction of the former inclination.
  • slot-like guides 14 are incorporated into the lower part of the side walls 3 of the frame 5, into which fitting bolts 15 which are fastened to the frame side walls 12, 13 engage.
  • the longitudinal axis of the guides 14 is parallel to the inclination of the funnel.
  • the displacement movement starts from a longitudinally arranged to a frame side wall 12 and by means of bearing blocks 17 of this flanged adjusting spindle 18, at one end of which a handwheel 19 is arranged for the introduction of force and at the other end of which a worm 20 is arranged to derive the force.
  • a worm wheel 21 meshing with this worm 20 is attached to one end of a synchronizer shaft 22 mounted in the frame side walls 12, 13.
  • the frame 5 is rotatably suspended with holes 29 provided in its side walls 3.
  • the frame 5 executes a pivoting movement which results in a displacement s in the direction of the funnel inclination, which corresponds to twice the eccentricity e of the eye 28 located on the gearwheel 26 relative to its center.
  • the frame In both end positions, the frame can be fixed relative to the frame side walls 12, 13 by means of clamping devices 30 screwed into the eyes 28 of the gear wheels 26 and into the fitting bolts 15.
  • Recesses 31 are provided in the side walls 3 of the frame 5, which allow the frame 5 to swing around the synchronous shaft 22.
  • the example described above is based on the requirement profile in which two end positions of the former are sufficient for adjustment. This is the case, for example, with a plurality of folding formers arranged next to one another then the case when one of the former is to be moved independently of the others in order to feed the products that arise in parallel during the first longitudinal folding process to a subsequent transverse folding process with a slight offset.
  • the lateral offset offers the necessary possibility of attack for a subsequent separation of the folded products, for example with grippers.
  • a former 42 is arranged downstream of a former entry roller 41. This is mounted in a frame 45 formed from side walls 43 and cross members 44.
  • a device 46 is articulated not far from the former nose 42 a, which serves for the fine adjustment of the former inclination.
  • This device 46 is mounted in axially adjustable manner in bearing blocks 47 connected to the frame 45 and, since it is known to the person skilled in the art, has not been described in detail.
  • the folding former 42 is rotatably mounted on an axis 50, which is installed transversely in the frame 45, via a linkage 48 attached to its rear side and a tube 49 attached to it.
  • the units also involved in the longitudinal folding process, such as funnel outlet rollers 51 and possibly existing perforating devices (not shown in the drawing) are also mounted in frame 45.
  • the frame 45 is mounted in the frame side walls 52, 53 in such a way that it can be displaced relative to the latter in the direction of the funnel inclination.
  • two slot-like guides 54 are incorporated into the side walls 43 of the frame 45, the common longitudinal axis of which lies parallel to the inclination of the funnel. Fit in these guides 54 on the frame side walls 52, 53 fasteners 55, the diameter of which is only slightly smaller than the width of the guides 54.
  • the semicircular ends of the guides 54 in cooperation with the fit bolts 55, form stroke limits for the displacement movement of the frame 45.
  • This displacement movement is based on an adjusting spindle 58 which is arranged longitudinally to a frame side wall 52 and is flanged to this by means of bearing blocks 57, at one end of which there is a handwheel 59 for the application of force and at the other end of which there is a worm 60 to derive the force.
  • a worm wheel 61 meshing with this worm 60 is fastened to one end of a synchronous shaft 62 mounted in the frame side walls 52, 53.
  • This synchronous shaft 62 has in the region of the side walls 43 of the frame 45 two pinions 65, 66 which cooperate with toothed rack profiles 67 which are incorporated in an edge 68 of a rectangular recess 69 in each side wall 43 which runs parallel to the funnel inclination.
  • the rack profile can either be worked directly into the side walls 43 or be formed by a toothed strip fastened on the edge 68.
  • the arrangement described above enables a stepless funnel adjustment, the largest dimension of which is determined by the length of the guides 54.
  • the folding former 42 can be fixed in any position by means of clamping devices 70 screwed into the fitting bolts and acting on the inner sides of the side walls 43 of the frame 45.
