Definitions

  • Upsizing folding machine with pull-in and / or folding rollers that can be adjusted to different folding gap widths and / or can be pivoted against one another in a resilient manner, which are each rotatably supported in two-arm pairs of pivoting levers and which each form a pull-in or folding point with a further folding roller, and with at least one folding pocket whose inlet gap has a minimum width and the thickness of the folded material is resiliently changeable.
  • Folding machines of the generic type which have folding rollers which can be adjusted to variable gap widths are known per se (CH-PS 390 287, DE-GM 92 03 930.8).
  • the folding pockets of these edging machines are, however, not with movable limiting elements on the inlet side provided that allow a change in the width of the inlet opening already in the folding pockets.
  • the invention has for its object to improve an edging folding machine of the generic type in such a way that a trouble-free transport of folding material through the entire machine and a good folding quality is ensured by the gap widths of the inlet gaps of the folding pockets of the thickness of the folding pockets even during processing of folding goods of very different thicknesses incoming incoming goods are automatically adjusted.
  • At least one of the finger-like and / or strip-like delimiting elements forming the inlet gap of a folding pocket can be moved to enlarge the inlet gap by actuating members of the pair of pivot levers which carries the pivotable roller of the pair of rollers which lies directly in front of the folding pocket Feed gap or fold gap forms.
  • the width of the inlet opening of each folding pocket based on an always present minimum width, which corresponds approximately to four to six times the thickness of a normal paper sheet, the width of the folding material
  • the width of the folding material To enlarge the inlet gap so far that a secure, trouble-free entry of the folded material into the folding pocket is ensured up to its stop and that, at the same time, in the area of the inlet opening of the folding pocket in question ensures the required folding material guide for the desired folding break or the folding edge to be brought about precisely is. It is particularly advantageous that the enlargement of the inlet opening takes place automatically as a function of the thickness of the folded material being processed.
  • the embodiment of the invention according to claim 2 makes it possible to achieve a disproportionate enlargement of the inlet gap of the relevant folding pocket in relation to the enlargement of the feed or folding gap located in front of the respective folding pocket.
  • This functionality is functionally very important, particularly in the case of very thick packages of folded goods, for a correct and trouble-free entry of the folded goods into the relevant folding pocket, and is particularly advantageous in connection with the embodiment according to claim 4.
  • the embodiment according to claim 4 has the effect that the minimum width of the inlet gap is maintained and not enlarged when the thickness of the folded goods is small.
  • the embodiment according to claim 3 is advantageous in that it achieves a more favorable angle of impact of the folded material on the guide bar with larger folded material thicknesses and thus also less deflection of the folded material when it enters the folding pocket.
  • the folding pocket 1 shown in the drawing consists of a multiplicity of staggered and spaced-apart lattice bars 2 and 3, each of which is connected to one another by cross bars 4 and 5 to form an upper lattice 6 and a lower lattice 7 Form inlet slot 8 together. While the upper grid 6, consisting of the bars 2, can be opened upwards about the axis of the cross bar 4, but usually remains in the functional position shown in FIGS. 1 and 3 to 5 due to its own weight or by locking, the lower one is off the lattice bars 3 formed lattice 7 limited pivotable downward about the axis of the cross bar 5.
  • an angle bar 10 is attached to an attached and welded in the transverse direction extending angle rail 10, which is provided with a right-angled to the plane of the inlet slot 8 ledge section 11, on which several hook-shaped bent obliquely to the level of the inlet slot 8 extending guide tongues 12 are integrally formed, the arcuate connecting section 13 to the strip section 11 forms the upper limiting element for an inlet gap 14 of the folding pocket 1.
  • the lower delimiting element of the inlet gap 14 consists of a flat leg 15 of an angle rail 16 which runs parallel to the plane of the inlet slot 8 and which is connected to the lattice bars 3 of the lower lattice of the folding pocket 1 and is arranged such that its flat upper side lies exactly in the plane, in which the bars 3 limit the inlet slot 8 on the underside.
  • round spacer blocks 17 are arranged outside the inlet width, on which the strip section 11 of the upper angle strip 10 rests with its round connecting section 13, so that the inlet gap 14 always has a minimum opening width b, which corresponds to the height of these spacer blocks 17. It is approximately 1 mm.
  • the angle rail 16 is limited in its upward movement by two shaft screws 18 each arranged on a lateral end section, which are screwed into a fixed skirting board 19 and protrude through the corresponding bores of the leg 15, and also by helical compression springs 20, which concentrically fix the shaft screws 18 enclose supported.
  • These helical compression springs 20 are supported on the underside on the baseboard 19 and on the upper side on the underside of the leg 15, so that the leg 15 is constantly pressed against the screw head 18 ′ located above it.
  • both the leg 15 of the angle rail 16 and the guide tongues 12 of the angle bar 10 protrude into the space between a feed roller W 1 and a folding roller W 3.
  • Die Folding roller W 3 forms a first folding point F 1 with a first folding roller W 2, while the feed roller W 1 forms a feeding point E with the first folding roller W 2.
  • the folding roller W 3 is also assigned a further folding roller W 4, which forms a second folding point F 2 with it.
  • This fold point F 2 is preceded in a similar manner by a second fold pocket, not shown in the drawing, into which the folded material passing the fold point F 1 can enter.
  • the feed roller W 1 is mounted on a fixed axis 21.
  • the two folding rollers W 2 and W 3 are each rotatably supported in two-armed pairs of pivot levers 22 and 23, which in turn can be pivoted about pivot axes 24 and 25 and are under the influence of tension springs 26 and 27, by means of which the folding roller W 2 counteracts the fixed feed roller W 1 and the folding roller W 3 are pressed against the also movable folding roller W 2.
  • the lever arms 22 'and 23' of the pairs of swivel levers 22 and 23 carrying the folding rollers W 2 and W 3 are each provided with finger-shaped extensions 28 and 29, respectively, which extend against the inlet gap 14 of the folding pocket 1 or against an inlet gap of another in the drawing Not shown folding pocket are directed and can act by means of pin-like actuators 30 and 31 on the ends of the legs 15 of the angle rails 16 that this is as shown in Fig. 4, of remove the stationary guide tongues 12 or the connecting section 13, which remain stationary due to the dead weight of the upper bar grille 6 or through interlocks, and thus widen the inlet gap 14.
  • the actuating members 30 of the pair of swivel levers 22 are arranged such that they have a distance a (see FIG. 5) in the rest position of the pair of pivot levers 22 from the upper side of the leg 15 of the angle rail 16, which corresponds approximately to the minimum opening width b of the inlet gap 14.
  • a see FIG. 5
  • the preferred embodiment described above has the advantage that the movement of the angle rail 16 can be achieved directly and without further reversing the direction of movement and also the Advantage that this results in a more favorable angle of incidence or entry of the folding material into the folding pocket in question, which results in less deflection of the folding material when entering the folding pocket in question.
  • This angle of incidence is indicated in FIGS. 1 and 3 by the arrow 34.
  • inlet gaps 14 can be expanded in an analogous manner by the pairs of swivel levers, each of which carries the swiveling folding roller of the folding point lying in front of it. It inevitably arises that the widening of the inlet gap corresponds in each case to the thickness of the folding material which increases from folding point to folding point.
  • the functional principle on which the invention is based can also be applied to upset folding machines which are provided with an automatic adjusting device which measures the thickness of the folded material from case to case and adjusts the pivoting lever of the folding rollers in such a way that the feed point E and the subsequent folding points F1, F2 etc. have the required gap width.
