Definitions

  • the invention relates to a method for cutting folded sheets and / or sheets, sheet stacks, booklets or the like which are transported by means of a conveying device and the like Stitch together or in a different way Joined sheets, in particular made of paper, usually have an unsightly appearance at the edge, and this makes trimming at least at the top and bottom edge, possibly also at the side edge or at all three edges mentioned necessary.
  • a special area of application is the production of specialist magazines, magazines, brochures, books and the like. Like. However, neither the method nor the device is limited to such articles or paper. For the sake of simplicity, reference is only made below to the production of illustrations.
  • the latter are preferably trimmed on three sides, namely above and below and opposite their binding margin. They leave the printing press in the so-called shed, ie seen in the direction of transport, their front end lies on the rear end of the preceding copy.
  • shed ie seen in the direction of transport
  • the deposit from the printing press is not absolutely uniform, which is why the degree of overlap is sometimes larger, sometimes smaller. This uneven formation of scales has hitherto made it difficult to trim the individual specimens.
  • the printing press has a much higher output than previously known machines for trimming the printed copies.
  • the specimens are cut individually or combined in small groups. This group formation is a complex operation, which results in a complicated device and therefore limited in its working speed. On the other hand, however, the known cutting devices do not permit any other trimming to be carried out.
  • the object of the invention is therefore to provide a method for cutting according to the preamble of claim 1 and an apparatus for performing this method, with which or with which a higher throughput speed is possible, and in particular one of the upstream printing press or the conveying speed corresponding conveyor speed allows the conveyor.
  • a method of the type mentioned is proposed, which is characterized according to the invention in that the sheets, stacks of sheets, booklets or the like are fed to a cutting device in the scale, ie overlapping in the transport direction at the front and rear, and cut in the scale, the cut being made in batches.
  • the working cycle of the cutting device which previously determined the working speed is no longer applicable, which is why the working speed can be increased considerably.
  • the throughput speed during cutting can be just as high as the ejection speed of the printing press. This allows the manufacture of the products in the exemplary embodiment, that is to say the illustrated, to be increased considerably. So far it has been common to print the magazines a. The like.
  • To cut with a cutting tool consisting of an upper and lower knife due to the circular cutting of the two cutting knives in a pulling, continuous cut. The latter is less suitable for cutting in the scale, which is why, according to a further process step, it is proposed that the cut be made in batches.
  • a further development of the method provides that the sheets, stacks of sheets, booklets or the like are cut simultaneously on two mutually opposite sides in the scale. This allows simultaneous editing of the upper and lower ends of the magazines.
  • a further embodiment of the invention provides that the scale is guided over a corner and the sheets, stacks of sheets, booklets or the like are subsequently trimmed on a third side in the scale. In all the cases mentioned, the cut is of course made in batches.
  • a device for carrying out the method of the type described above is characterized according to the invention by a transport device for the scale formed from sheets, stacks of sheets, booklets or the like, and at least one cutting device arranged on the side of the transport device for batchwise cutting.
  • the device can be an extension of the device transporting the scale, which leads past the cutting device or, with simultaneous trimming, leads through the gap between the two cutting devices at two opposite ends.
  • the cutting device operates according to one of the marking features in batches, because this is advantageous compared to the continuous drawing.
  • each cutting device consists of a disk-shaped, toothed, drivable circular knife and a counter knife interacting therewith.
  • the serrated circular knife is comparable to a conventional saw blade or a side milling cutter. With regard to its tooth formation, these elements can serve as a model, but taking into account the material to be cut, in particular paper.
  • the counter knife is preferably disc-shaped and provided with a circumferential, circular cutting edge.
  • the cut is therefore made with the help of a partial circumference of the counter knife and a cutting edge of a tooth.
  • the counter knife is also expediently drivable.
  • a further development of the invention provides that the axes of the toothed circular knife and the counter knife are offset in the transport direction and in particular the axis of the counter knife lies in front of that of the toothed circular knife.
  • the geometric axis of the toothed circular knife is preferably offset by approximately the amount of its radius. If both knives are driven, a further embodiment of the invention provides that the peripheral speed of the counter knife is approximately the feed speed of the scale and that of the toothed circular knife is approximately 10-50 times thereof.
  • the scale 1 consisting of individual specimens 2 comes from a printing machine (not shown) and is moved forward in the direction of the arrow 3 with the aid of a transport device 4. It first reaches the area of a straightening station S, where the longitudinal edges are aligned. Subsequently, the scale 1 passes through a first cutting station 6, which essentially consists of two mutually opposite cutting devices 7, which can be adjusted at least in the direction of the double arrows 8.
  • Each cutting device comprises a disk-shaped, toothed circular knife 9 which can be driven by a motor and a counter knife 10 cooperating therewith.
  • the latter is preferably also disk-shaped and. drivable. It has a circular cutting edge 11 which interacts with the cutting edges 12 of the teeth 13 one after the other, so that a batch-wise cutting process occurs.
  • the axis 14 of the toothed circular knife 9 is offset from the axis 15 of the counter knife 10 in the transport direction 3 or 16.
  • the offset of the geometric axes can correspond, for example, to the radius of a pitch circle 17.
  • the counter knife 10 is located completely below the plane of the scale 1.
  • the arrangement is in particular such that a lower band 18 or the underside of the scale 1 extends tangentially to the cutting edge 11.
  • the geometric axis 19 of the knife 9 expediently also lies approximately in the plane of the scale, in particular the upper surface of the lower belt 18.
  • the latter is preferably a toothed belt.
  • an upper belt 20 opposite the lower belt is comparatively smooth and soft in order to be able to nestle well against the uneven contour of the scale.
  • the transport device 4 includes the two upper and lower belts on the side at least one intermediate conveyor belt 21, but in particular two intermediate conveyor belts 21.
  • the side spacing of the belts can be changed to allow different widths of the scale. For this reason, the elements of the straightening station 5 and the cutting devices 7 can also be adjusted or set in the direction of the double arrows 8.
  • the smallest format to be processed is decisive for the bandwidth.
  • each cutting tooth 13 of the toothed circular knife 9 extends at a clearance angle 22 of approximately 0 to 20 °.
  • the peripheral speed of the counter knife or the cutting edge 11 of the counter knife 10 corresponds approximately to the feed speed of the scale 1 at this point.
  • the speed of the toothed circular knife, which has approximately the same diameter, is significantly higher, which results in a circumferential speed which is approximately 10-50 times that of the cutting edge 11.
  • the two parallel upper and lower ends of the specimens 2 are trimmed.
  • the scale 1 is guided over a corner by means of a suitable device 23, subsequently straightened using a second straightening station 24 and cut at a second cutting station 25.
