Definitions

  • the invention relates to a cross cutting device with the features of the preamble of claim 1.
  • a cross cutting device is known from CA-Al-2, 176, 282, from which the present invention is based.
  • this cross cutting device is very complicated in construction and therefore expensive.
  • the cross cutting device of the present invention according to the features of claim 1 has a relatively simple construction, since the counter pressure tool is a simple cylinder or a counter cutting bar.
  • the following invention describes a variable cross cutter that fulfills all technical conditions and can also be manufactured inexpensively.
  • the cross cutting device consists of the following components:
  • the frame construction of the cross cutting device can be made from different materials (aluminum, cast steel, steel, etc.)
  • the pair of feed shafts which has the task of introducing a material or material web into the unit, can either be attached directly to the cross-cutting device and also driven from there, or it can be built up separately, or can already be part of an existing machine.
  • the task of this device is to introduce the material into the cross-cutting device at a constant or variable speed.
  • a register control can also act on the feed station if cross-cutting or perforation with printed registers is required for printed webs.
  • the impression cylinder serves as a counter bearing for the cutting or perforating knife when cutting the material web during the cutting process.
  • this is a very precisely mounted counter-pressure cylinder, which is either made of hardened steel or other hard material or is equipped with exchangeable hardened strips.
  • the surface speed or speed of the impression cylinder is adjusted to the web and can, if necessary, also from a existing base machine can be driven from.
  • a counter-cutting bar can also be provided, which works together with the cross-cutting knife.
  • the cross cutting rotor marked with 4 is used to hold cross cutting knives or cross perforation lines of all kinds.
  • cross-cutting knives are installed with the aid of a quick-action clamping device.
  • Other types of fastening are also conceivable and possible here. It is essential, however, that this cross-cutting rotor, in conjunction with the quick-action clamping bar, enables quick replacement with perforating lines and cutting knives, which is a clear advantage over existing systems.
  • the cross-cutting rotor has its own electromotive drive (servo motor), which influences the rotor speed with a specially designed control.
  • servo motor electromotive drive
  • only one knife or a maximum of two knives are attached to the rotor itself; in other exemplary embodiments, more knives are also conceivable. Due to the acceleration and deceleration compared to the web, different section lengths can now be cut or perforated.
  • the cross-cutting rotor assumes the web speed only in the range of + 10 ° around the cutting point and in the meantime either runs at its circumferential speed, measured on the web, slower or faster. Through this act the actual length of the web is reached.
  • the cross-cutting rotor has a special external shape that is of essential importance.
  • the cross cutting rotor has a particularly favorable and suitable shape that combines several advantages. On the one hand, large cross-cutting forces are absorbed by a high bending resistance due to the particularly suitable sword shape.
  • the second advantage is that the remaining parts that deviate from the normal circular shape and are omitted represent a significant saving in mass.
  • the special shape of the rotor has the advantage over other constructions that high bending moment with low weight is present, as well as the further advantage that due to the construction of the width "X" the depth of penetration into the web can be varied depending on the thickness of the goods and the angle of entry of the knife can and thus the cutting rotor is also suitable for cutting thick webs.
  • Figure 2 shows an advantageous embodiment of the cross cutting rotor, in which a further essential advantage is integrated.
  • Figure 1 it can be assumed that, while the rotor is working, in contrast to a normal round shaft, a correspondingly large amount of air has to be displaced and therefore the air resistance also counteracts the drive power.
  • the generation of this effect is also unfavorable for the further processing of material webs or cut sheets or is disruptive for operating personnel.
  • differently large and different numbers of transverse bores were made in the rotor transverse to its longitudinal axis. These cross holes significantly reduce air displacement. It is also important that the installation of these cross bores additionally reduces the mass considerably, which is further advantageous.
