Definitions

  • the invention relates to a device according to the preamble of patent claim 1.
  • Such cutting devices are known with regard to the usual cutting technology used.
  • their application is directed to the cutting of paper webs and also to the cutting of individually designed printed products which have been created by prior cross-cutting and which are fed to the cutting device in a continuous process according to the transport speed used either to a gap or in the so-called shingled stream.
  • the shingled stream is the common form, so that the shingled stream is then also decisive for the further processing processes.
  • the cutting of individually designed printed products requires a transport device with which the products are conveyed through the cutting gap and at the same time held down so that the attacking cutting forces do not Cause slipping.
  • the arrangement according to DE-A-3022772 has conveyor belts above and below the transport path, which feed the material to be cut to the cutting device for edge trimming.
  • DE-V-8401628.0 shows a similar cutting device in connection with a ribbon line, which is provided for transporting the material to be cut, but the position of the ribbon line is based on the implementation of a separating cut, that is to say a cut that is more or less within the width of the printed product takes place, turned off.
  • the associated knife is designed as a one-piece double knife, so that the strip lying between the cutting edges results in a chip approximately the width of the cutting edge distance.
  • the ribbon cable is straight and close to the cutting line, because the compression of the flexible paper plays a major role in the cutting area.
  • Another device for cutting out which is more variable with regard to the strip width of the cutout, works with offset circular knives, the first longitudinal cut being made by the first coming circular knife and the second longitudinal cut being made by the offset circular knife.
  • This type of cutting out has the advantage that the reaction of the chip, which can be relatively rigid and resistant in the case of printed products in the form of scales, is to be kept low.
  • the known cutting devices are characterized by the table-shaped design due to the associated transport devices.
  • the transport path describes a flat surface because the material to be cut is fed in and out in a straight line.
  • the footprint of such cutting devices is large, and their characteristic structure also means that the entire processing line, on which the production runs in-line from the roll via the printing press and other units to the ready-to-use printed product, is relatively elongated. If the cutouts mentioned are to be made, however, additional space is required in the table-shaped cutting devices because of the offset circular knife arrangement. Investment, operating and maintenance expenses increase almost proportionally, especially since longer processing distances can also be made more difficult technically.
  • the cutting out affects an application of increasing importance because of the production versatility that can be achieved with it, because it enables the customary format division, which is based on the circumference of the printing cylinder and mostly involves transverse folds, to be avoided. This results in a greater variety of products with regard to small, more manageable printed products.
  • a section is designed whose length corresponds to a single or multiple of the circumference of the printing cylinder. This section is subsequently rotated by 90 ° with respect to the transport direction so that the product edges or image edges originally lying transverse to the web development direction come to lie parallel to the transport direction.
  • Cutouts are used when there are pressure-free zones or overfills with overlapping printed images that have to be removed between the adjacent print products.
  • the object of the present invention is to limit the cut-out-enabling products for scale-shaped products to the smallest possible space, thereby favorable conditions for the to create the necessary contact pressure with high cutting quality.
  • the features of the characterizing part of claim 1 include that the shingled stream is cut and transferred simultaneously in one operation with the cutting device. If the counter knife device also has the role of a transfer cylinder, the shingled stream exits with the trimmed sections in the opposite direction to the feed direction, and the outlet of the cutting device is thus on the side of the inlet. While in the case of a table-shaped arrangement of the cutting device, each offset circular knife also normally requires a counter knife, the cutting device according to the invention manages with only one counter knife device in the case of two offset circular knives.
  • the longitudinal cutting device has clamping jaws for holding the stack of sheets on the fold edge, and furthermore the stack of sheets between the clamping bands receiving them.
  • the required synchronization of the sequence of the lower and upper band line with the rotary movement of the circular knives and the counter knife device is achieved by using toothed belts for the band lines on the one hand and toothed belt pulleys in connection with the circular knives and the counter knife device on the other.
  • the feed belt 10 takes over the transport of the printed products in the form of scales as sections P B to the cutting device.
  • the dimension of the visible lateral edge of a section P B results from the width of the folded or unfolded web strands; the dimension of the section P B transversely to the feed belt is approximately the width B comprising several product lengths.
  • the cutting device consists of deflection rollers 6, 7, 8, 9, set up for the strip lines, a deflection drum 3 and the core piece, the counter knife device 1 and the circular knives 2.
  • the loop of the lower band line 4 includes the deflecting rollers 6, 9 and the counter knife device 1; the loop of the upper ribbon line 5 runs over the deflection rollers 7, 8, the deflection drum 3 and the circular knife 2. It goes without saying that the unwinding in one loop runs in the opposite direction to the unwinding in the other loop.
  • the transport path of the printed products within the cutting device extends from the input E via the deflection drum 3 and the counter knife device 1 with the circular knives 1 set to the output A.
  • input E and output A are a pull-in or discharge gap between the lower and upper ribbon lines 4, 5 educated.
  • the conveyor belt 11 is arranged for the removal of the trimmed products P b .
  • the difference in height H that can be found between the feed belt 10 and the conveyor belt 11 is due to the arrangement of the deflection drum 3 located approximately above the counter knife device 1 within the cutting device. Associated with this, a change of curvature takes place for the lower and upper ribbon line 4, 5, and a greater wrap around the ribbon line and thus the printed products in the area of the counter knife device 1 is achieved.
  • the diameter of the deflection drum 3 is selected so that the printed products are not subject to buckling during their contact with them, but their position in the scale flow is stabilized by the predetermined curvature.
  • the diameter of the counter knife device 1 must be so large that a suitable distance between the offset circular knives 2 can be achieved and that the accessibility of the circular knives 2 is also guaranteed.
  • the diameter of the counter knife device 1 depends on the size of the grooved rings 1/1 to be used.
  • the upper ribbon line 5 runs on a pitch circle of the drive and tensioning body 2/1, which is smaller than the pitch circle attributable to the cutting edge of the circular knife 2.
