Definitions

  • the invention relates to a device with which paper webs can be folded by machine. Before or after such, the Messerfalz- or pocket folding technique using folding devices longitudinal slitting devices are present to bring, for example, the already folded sheet or subsequently to be folded sheet by cutting longitudinal edges in the correct width or to cut the product into several benefits.
  • folding devices such as pocket folding devices with upstream or downstream tool shafts.
  • tool shafts can be equipped for slitting, but also for perforating or scoring.
  • upper and lower blades can be used, which are each mounted rotatably on a respective upper and lower shaft. With such cooperating two circular knives, the web can then be cut in a shear section in the longitudinal direction, that is to say in the running direction of the web. Due to manufacturing tolerances of the cutting blade, it is very difficult to bring the cutting gap between the respective upper and lower blade as possible to zero in order to achieve the highest possible quality of cut.
  • the circular blades can be moved axially on the respective upper or lower blade shaft.
  • the conveying speed of the paper web between the tool shafts and the folding shafts of the folding device must be exactly the same.
  • the shear cut cutting principle implies that the upper and lower knives are slightly larger in diameter than the transport rolls present on each cutting shaft and conveying the paper web between them. Due to this overlap, however, the cutting blades have a slightly smaller speed component in the cutting direction than the paper web, despite the higher peripheral speed due to their larger diameter. This comes it is the shear cut to a kind of pulling through the paper web through the cutting blade, which leads to a very poor quality cut especially for thin papers.
  • the present invention seeks to form the tool shafts upstream or downstream of folding devices such as knife shafts in particular so that the highest possible quality paper cut or a comparable longitudinal processing can be generated.
  • the lower circular blade is mounted freely movable on its blade shaft, while the associated upper circular blade is rotatably mounted on its upper shaft.
  • the lower, rotationally driven blade shaft is connected directly or indirectly via a gear to the upper shaft, such that the upper blade shaft receives a comparatively higher rotational speed. This can also be achieved by another own drive for the upper cutter shaft.
  • This higher rotational speed of the upper shaft has the consequence that the upper circular blade has a correspondingly high rotational speed.
  • the lower circular blade can also be attached to the upper one. In this way, it is ensured that the two cutting blades in the cutting point with the paper web have a higher speed component in the running direction of the web than the web itself, so that a high-quality shear cut can be produced.
  • such a pulling longitudinal section can also be achieved by arranging a corresponding gear between the shaft to be rotated by any desired drive and one of the two circular knives. It would also be possible to set one of the two or both circular blades by relatively separate drives in relation to the or the rotatively driven waves in relatively faster rotation.
  • the two cutting blades cooperating cooperating knives are rotatably mounted on their tool shafts.
  • the one or both of the above or from below of the paper web adjacent transport rollers are freely rotatably mounted on the respective tool shafts.
  • the transport rollers can then be driven to rotate so that they transport the paper web conveyed through between them at the desired web speed to the folding rollers or away from the folding rollers.
  • the tool shafts can be driven correspondingly faster rotational, so that the above-mentioned high-quality shear cut can be produced.
  • the production of a freely rotatably mounted transport roller is structurally simpler and thus economically cheaper than the comparable construction for a free rotatably mounted circular blade.
  • the adjacent each of the top and bottom of the paper web transport rollers can be driven by, for example, auxiliary shafts. It would also be possible to drive only one of these in each case two transport rollers and mitzuschleppen the other transport role as it were by their investment in the paper web.
  • the cutting quality of the longitudinal cuts or cuts to be produced in a paper web in conjunction with a folding device can also be increased by bringing the cutting gap between the upper and lower knives as close as possible to zero.
  • a minimally wide cutting gap can be produced in that one of the opposing circular blades is pressed against the counter blade via a spring element.
  • the rotatably mounted on a shaft circular blade loaded by a spring element in the axial direction, so that it always frictionally rests with its peripheral edge on the counter blade.
  • This spring element can, as shown in the drawings embodiments, preferably be an elastically deformable ring such as in particular a rubber ring or even a steel spring or another spring element.

Between the two rubber inserts 44, 45 of the lower and upper transport roller unit 40, 50, the paper web 28 runs.
  • a lower holding jaw 60 is rotatably mounted on the lower shaft 26 via a screw 62.
  • the holding jaw 60 is surrounded by a ball bearing 64 which carries an outer retaining ring 66.
  • the retaining ring 66 is thus freely rotatably mounted on the holding jaw 60.
  • the ball bearing 64 is arranged by means of a locking ring 61 in the axial direction 59 fixed to the lower holding jaw 60.
  • the lower circular blade 70 is clamped between a re-entrant shoulder 67 of the retaining ring 66 and a held by a locking ring 69 in the axial direction 59 on the holding jaw 66 spacer.
  • the ball bearing 64 of this lower circular blade 70 is freely rotatably mounted on the lower holding jaw 60 and thus on the lower shaft 26 in the same manner as the retaining ring 66.
  • the lower circular blade 70 cooperates with an upper circular blade 74.
  • This upper circular blade 74 is rotatably mounted on an upper jaw 76 which is rotatably mounted on a screw 78 on the upper shaft 24, and is loaded by a spring ring 80 in the axial direction 59, that is in the longitudinal direction of the two longitudinal axes 82, 84 of the upper shaft 24 and lower shaft 26.
  • the spring ring 80 thus presses in the axial direction 59 against the upper circular blade 74.
  • the upper circular blade 74 is applied in the axial direction 59 laterally pressing against the lower circular blade 70, as shown in Fig. 1.
  • the two Umf margins of the two circular knives 70, 74 thus produce a shear cut with a size going to zero cutting gap. In this way, a clean longitudinal section can be generated and thus, for example, one side edge 83 can be separated from the remaining paper web 28 in terms of quality.
  • Each cutting edge of both circular knives 70, 74 each has a - not shown in the drawing - hollow grinding.
  • the spring ring 80 (rubber ring) is held framed by a press ring 81 laterally.
  • the pressing ring 81 has an internal thread and the upper holding jaw 76 has an external thread, so that the pressing 81 can be screwed onto the holding jaw and thereby the spring ring 80 can be prestressed.
  • the pressing ring is fixed in its adjusted position.
  • a lower gear 90 is rotatably mounted on the lower shaft 26, which is actively rotatably driven, in the present case 24 teeth.
  • This lower gear 90 meshes with an upper gear 92, which has, for example, 20 teeth and which is also rotatably mounted on the upper shaft 24.
  • the gear consisting of these two gears 90 or 92 causes the upper shaft 24 to have a rotational speed 20 percent greater than the lower shaft 26.
  • the upper circular blade 74 mounted on the upper shaft 24 in a rotationally fixed manner has a correspondingly increased rotational speed , which transmits this upper circular blade 74 by its frictional engagement with the lower circular blade 70 on this lower circular blade 70.
  • the lower circular blade 70 assumes this increased rotational speed, since it is freely rotatably mounted on its lower shaft via the ball bearing 64. In this way, a relation to the running speed of the paper web 28 sufficiently increased rotational speed of the circular blade 70, 74 can be ensured.
  • the running speed of the web 28, however, is not increased.
  • the running speed of the paper web 28 is based on the rotational speed of the lower transport roller unit 40, which is non-rotatably mounted on the lower shaft 26.
  • the rubber insert 44 of the lower transport roller unit 40 transmits its rotational speed to the upper transport roller unit 50 with the freely rotatably mounted upper rubber insert 45.
  • the paper web 28 is thus transported by the two rubber inserts 44, 45 of the two transport roller units 40, 50 at a speed in the web running direction, which is determined by the rotational speed of the lower shaft 26.
