Definitions

  • the invention relates to a cutting device for Cutting a material web into partial webs, with a Knife arrangement that is transverse to the direction of travel of the material web is movable and a first knife unit on one side of the material web and a second knife unit on the other side of the material web, the first knife unit having a drive Has positioning unit.
  • the invention is intended to be based on a paper web can be described as an example of a material web. But you can also use other material webs, for example Cut foils with the cutter.
  • Paper webs are often made with widths, that are too wide for later use. you will be therefore in one of the last editing steps cut the necessary or desired width. This creates several side by side from one material web running partial webs on partial web rolls be wound up. You can also cut straightening the edges of the material web to reach.
  • the knife arrangement here has two knife units on, also known as the upper knife and lower knife be, if the knife arrangement according to the principle of Silhouette works. So that the cut is done cleanly both knife units must be relatively accurate be positioned to each other. So far there are two possibilities. In one case, when repositioning the upper knife with the lower knife mechanically connected. Here, however, the material web may no longer present between the two knife units be. Both units are paired move together to their new position, fixed there and then decoupled from each other again. This requires one drive and one for each knife arrangement Positioning unit and in addition the mechanical coupling device.
  • the disadvantage here is that one Can not make adjustment as long as a paper web runs through the cutting device. It is therefore for example not possible a second set of Knife arrangements for a subsequent cutting process to position while still a web of material is cut to keep set-up times short.
  • the invention has for its object an accurate and quick adjustment of the knife arrangement enable.
  • This task is the cutting device solved at the outset according to the invention, that between the first knife unit and the second Knife unit a wireless signal transmission path is formed and the second knife unit has a tracking device.
  • the second knife unit is tracked the first knife unit, whereby the signal transmission path ensures that the necessary positioning signal at the the position of the corresponding to the first knife unit in the area the second knife unit is available.
  • the second knife unit is positioned So no longer compared to a fixed point that may be shift compared to that of the first knife unit can, so that a possibility of error is excluded becomes. Since the second knife unit is the first Knife unit is tracked, there is also a very quick adjustment. Both knife units are adjusted practically at the same time.
  • At least one end of the signal transmission path a magnetic field generating device arranged.
  • a magnetic field can cover almost any material especially a paper web, penetrate and accordingly on the other side the paper web.
  • There is a magnetic field therefore a particularly suitable signal that over the signal transmission path to the other knife unit can be transferred.
  • Furthermore, can to form a magnetic field so that it at least over a short distance is directed, so that also a relatively precise positioning of the other knife unit is made possible.
  • the magnetic field generating device is advantageous as Electromagnet trained.
  • the magnetic field can therefore be switched on and off, which is particularly the case It is an advantage if material webs are used with the cutting device be cut, which has an electrical conductivity exhibit. You can then in continuous operation Turn off the electromagnet so that no magnetic field there is more between the two knife units.
  • the tracking device through a magnetic coupling between the first and the second knife unit is formed.
  • the magnetic field can therefore be used for two purposes at the same time use. Firstly, with the help of the magnetic field the position of one knife unit to the other knife unit transfer. On the other hand, you can use the achieve magnetic coupling in one movement one knife unit the other knife unit becomes. A magnetic field is able to perform the coupling without contact, i.e. it is no mechanical connection between the two knife units necessary.
  • a magnetic field generating device is preferably on both knife units arranged, their field orientation is directed in the same direction. This results in a very strong magnetic coupling. This is stronger than the simple coupling of a magnetic field to an opposite piece of iron.
  • the two opposite Magnetic field generating devices are therefore position the two knife units so that the deviations in the fields are minimal. With in other words, the two knife units are automatic so positioned relative to each other that the state of least energy. At a corresponding arrangement of the magnetic field generating devices this is exact on the knife units the relative position that is desired.
  • the second knife unit advantageously has one Self drive on the one with a receiver at the end of the Signal transmission link is coupled and the second Align the knife unit with a local signal maximum.
  • This measure can additionally or alternatively the "magnetic drive” may be provided.
  • the self-propulsion the second knife unit is an additional drive.
  • positioning can be simplified since the knife unit is moved so that the Receiver a local maximum of the signal transmission path perceived signal.
  • the signal strength decreases from this maximum. So it is relative easy to determine the maximum.
  • the signal is advantageous due to electromagnetic Waves or formed by an electrostatic field. Both are ways to get a directional signal generate, for example, a beam of light through the paper goes through. Other electromagnetic waves, such as "radio signals" are also possible. Such waves or fields can be relative easy to create and also relatively easy to perceive, so that the appropriate receivers or sensors can be realized with relatively little effort.
  • the first knife unit is advantageously used as a lower knife educated.
  • the first knife unit must be exactly on that Format of the material web to be cut set will.
  • the upper knife, which is roughly in the same position must be followed can be somewhat less precise than the lower knife can be positioned. Accordingly the tracking option is sufficient.
  • a cutting device 1 shown in FIG. 1 is used for slitting one shown with dashed lines Paper web 2 (or another web of material).
  • the cutting device has a first one Knife unit 3, which is arranged below the paper web 2 is, and a second knife unit 4, the is arranged above the paper web.
  • the first knife unit 3 has a knife 5, which has a motor 6 can be driven.
  • This knife 5 is also called Inscribed "lower knife”.
  • the second knife unit 4 has a knife 7, which is also referred to as an "upper knife” becomes.
  • Both knives 5, 7 are for the sake of Overview shown at a distance from each other. For the actual cutting process, they are brought closer together, so that they work like a silhouette, i.e. the two knives 5, 7 partially overlap and enter the paper web 2. It it is obvious that the two knives 5, 7 do this positioned relatively exactly to each other in the axial direction must be so that the cutting result is the desired one Quality.
  • the knife unit 3 is mounted on a carriage 8 which on a rail 9 transverse to the direction of the paper web 2 is displaceable. This allows the position of the lower knife 5 in the width direction of the paper web change so that different cutting lines can be generated. For example, the widths of those cut from the paper web 2 Partial lanes vary. It is shown schematically that the wheels 10 of the car 8 are driven. The positioning the car 8 itself is known. One on this provided positioning device is not closer shown.
  • the knife unit 4 is also arranged on a carriage 11, the with the help of wheels 12 on a rail 13 is suspended.
  • the wheels 12 are not driven here.
  • the lower knife unit 3 has an electromagnet 14, which is put into operation via a control unit 15 can be.
  • the upper knife unit 4 has one Electromagnet 16 on, via a control unit 17 can be put into operation. Commissioning the electromagnet takes place in that coils 18, 19, which are placed around yokes 20, 21 with a direct current be charged. Here, the coils 18, 19 guided in the same direction, so that the electromagnets 14, 16th generate a magnetic field 22.
  • the north pole N of the electromagnet 16 is the south pole S of the electromagnet 14 opposite, so that the two electromagnets 14, 16 tighten each other. If the Electromagnets 14, 16 are put into operation before the carriage 8 is moved, then the carriage 11 is the upper knife unit 4 when moving the carriage 8 the lower knife unit 3 automatically tracked.
  • the distance between the yokes 20, 21 is here Exaggerated for reasons of clarity. He will actually be only a few millimeters in size. Basically, all you need is a distance, enough paper web 2 between the magnets lead through.
  • the upper knife unit does not have its own drive required. This is when the lower one moves Knife unit 3 using the magnetic field 22 automatically updated.
  • the magnetic field 22 of the electromagnet 14, 16 has two functions: First, sends it as a signal from the upper knife unit 4 Information about the position of the lower knife unit 3. On the other hand, it also serves to drive the upper knife unit 4 to transmit necessary forces.
  • Fig. 2 shows another embodiment in which parts, which correspond to those of FIG. 1, increased by 100 Reference numerals are provided.
  • the one shown in Fig. 2 Cutting device 101 also has one lower knife unit 103 and an upper knife unit 104, the lower knife unit 103 being a knife 105 and the upper knife unit 104 has a knife 107.
  • the knife 105 of the lower knife unit 103 is driven by a motor 106.
  • the lower knife unit 103 is on a carriage 108 with driven wheels 110 movable.
  • the carriage 111 of the upper knife unit 104 points in this embodiment, however, a drive 23 with which he can be moved on the rail 113 can.
  • This drive is via a control device 24 controlled.
  • the control device 24 is with a sensor 25 connected.
  • the sensor 25 serves as a receiver Signal from a transmitter 26 on the lower Knife unit 103 is delivered. Between the transmitter 26 and the sensor 25 is thus a wireless signal transmission path trained over which a signal can be transferred.
  • This signal can, as in 1 explained, for example from a magnetic field 22 exist through the paper web 2, 102 is known not to be disturbed.
  • Field 27 located along the transmission line trains, but also act in other sizes.
  • a light beam can be provided which is able to on the other side of the paper web to be noticed.
  • the signal can also pass through another electromagnetic wave in the invisible Area are formed, for example by a Radio signal.
  • Field 27 can also be a act electrostatic field generated by the transmitter 26 becomes.
