Definitions

  • the proposed invention relates to the technical field of changing the position of knives according to the preamble of the appended claim 1.
  • Devices of the type mentioned are used, for example, to use relatively wide webs with the help of at least one - generally with Using multiple slitting devices to cut into narrow strips so that these narrow strips can then be wound up, for example, into smaller rolls.
  • Such a device is known, for example, from German Patent 41 07 227.
  • a so-called traverse is provided, that is to say a connection, arranged transversely to the running direction of the web to be processed, between two frame parts, for example of two side walls, which is shaped in such a way that several knives can be held thereon.
  • the knives are able to cut the web in the running direction so that the narrow strips mentioned can be cut out of this web.
  • several knives are often distributed over the width of the web to be cut. The position of these knives can be changed to enable strips of different widths to be cut as desired.
  • Each of the knives required for a cutting process works together with a corresponding counter knife.
  • an upper knife works with a lower knife. So that the adjustment can be carried out relatively easily, i. that is, it is relatively easy to change from one width of strips to be cut to another, so-called bottom knives are often used as counter knives, which contain several cutting surfaces, each of which is suitable, together with an upper knife in the desired sense.
  • REPLACEMENT BLA ⁇ (RULE 26) to work.
  • RULE 26 REPLACEMENT BLA ⁇
  • a mixed form is also possible, so that, for example, an upper knife can work with one of several cutting edges of an associated lower knife and, moreover, is additionally able to cooperate with several such lower knives as desired.
  • the upper knives are generally fastened to knife holders which can be moved and adjusted transversely to the width of the web to be processed.
  • the aforementioned known device uses lighting devices, such as signal lamps, according to which the respective holder of a slitting knife can be aligned. A magnifying glass is required here for alignment, so that the respective knife holder can be aligned with the desired accuracy on the so-called traverse. By today's standards, this alignment process is still quite time-consuming.
  • efforts are made to manufacture the individual parts of the cutting device as inexpensively as possible. This means, for example, that the respective lower knife or knives, with which a so-called upper knife interacts, must be manufactured as inexpensively as possible.
  • the so-called lower knife has so far been designed
  • REPLACEMENT BLA ⁇ (RULE 26) tet that it extends, for example, over the entire width of the web to be processed in one piece and contains cutting edges at regular intervals.
  • the known lower knife shows a multitude of such cutting edges which have to be at a certain distance from one another if the widths of the strips to be achieved are to be kept as precisely as possible. This means that a large number of tolerances must be observed when the lower knife in question is manufactured. Of course, the requirements for accuracy in manufacture make the product more expensive, in this case the lower knife. In addition, there is a requirement on the part of the operator of such a mechanical device to be able to produce other widths of strips which differ from the distances between the cutting edges of the lower knife used in each case.
  • a web to be divided into strips 1, 2 and 3 in its running direction runs through a corresponding mechanical device.
  • This mechanical device contains, among other things, so-called upper knives 4 and 5, and lower knives 6, 7, 8 and 9.
  • Each lower knife has one A large number of cutting edges, for example the cutting edges 10, 11, 12.
  • Each two cutting edges of a lower knife enclose a mutual distance, the so-called division.
  • the cutting edges 14 and 15 include, for example, the distance 16 from one another, which is referred to in the technical field as the division between the cutting edges 14 and 15.
  • Each of the upper knives 4 and 5 can cooperate with any desired cutting edge.
  • each of the upper knives is held in a so-called holder 17 or 18 and fastened to it.
  • Each holder 17 or 18 or other holders of this type can be moved or moved along a rail 19 or fixed to it, this rail being usually referred to in the technical field as a cross member.
  • the rail is fastened to its end faces in the associated machine frame and therefore does not move itself.
  • the holders 17 and 18 of the upper knives 4 and 5 are also designed such that they are first rotated relative to the rail before the holders 17 and 18 are moved in such a way that the knives are released from the cutting edges 11 to 12 etc.
  • the respective lower knife so to speak, can emerge from the so-called cutting grooves 20 of the respective lower knife before the holders 17 and 18 can be moved in the direction of the arrow 21 so that the respective upper knife can interact with a different cutting edge than before for another cutting job.
  • Spacers or something similar can be inserted between the respective lower knives.
  • the spacer sleeve 22 is inserted between the bottom knives 6 and 7, the spacer sleeve 23 between the bottom knives 7 and 8. All the bottom knives and spacing sleeves are pushed onto a shaft 24, the shaft 24 being known and therefore not shown again rotatable in the corresponding dimension machine frame is stored.
  • the shaft 24 can be provided with a rotary drive.
  • spacer sleeve No such spacer sleeve, for example, is inserted between the lower cutters 8 and 9.
  • spacer sleeves can also be regarded as spacer plates or have a crescent-shaped cross section, so that they represent an open Latin C approximately. If this is the case, then it is not necessary to remove the lower cutters 6, 7, 8 and 9 from the shaft 24 if the spacer sleeves 22 and 23 are to be replaced, for example. It is sufficient to loosen the lower knives 6 to 9, which are usually screwed onto the shaft 24, so that they can be moved slightly parallel to the geometric axis of the shaft 24 in the direction of the arrow 25.
  • the width 26 of the spacer sleeve 22 or a corresponding spacer plate or spacer thus becomes different.
  • the width 26 of the respectively selected spacer sleeve or corresponding spacer does not necessarily have to correspond to the distance 13 which exists between two cutting edges of the lower part.
  • the width 26 can be quite different from that Distance 13.
  • the lower knives 6 to ') etc. must be manufactured for their part and are therefore necessarily subject to a corresponding accuracy, which is determined by the manufacturer. lation process is conditional. This accuracy should be such that it does not make the individual lower knife unnecessarily expensive.
  • inexpensive manufacture requires relatively coarse tolerances, so that it can happen, for example, that the distance 13 does not necessarily have to be the same as the distance 16. This applies all the more, the longer the lower knife selected, ie the wider it is shown in the figure.
  • lighting devices 28 in the form of signal lamps or the like are provided, so that the operator can very quickly find the point at which the respective holder of the respective knife is positive ⁇ must be on.
  • These signal lamps are in turn attached to the rail 19 in the direction of arrow 25 or parallel thereto or parallel to the direction of arrow 21 in such a way that such a signal lamp lies next to the other.
  • Two signal lamps maintain a distance 27 from one another which is considerably smaller than, for example, distance 13 or distance 16.
  • five such signal lamps or lighting devices come to the width of a distance 13 or 16 the distance 27 is smaller than the division of the associated lower knife, for example a fifth or a quarter, but at most half the distance 13 or the distance 16.
  • five or more such lighting devices 28 come at a distance 13 or for example 16.
  • the lighting devices are attached to a support 29 in such a way that at least one such lighting device is provided per support 29.
  • several such lighting devices can also be arranged on a carrier 29, for example in powers of two such as 128 or 256.
  • Other supports 29, 30, 31 and 32 are fastened along the rail 19 to their or an associated part, which means that the supports 29 to 32 appear to be arranged side by side in the figure.
  • a control device 33 which is connected to the support 29 by means of control lines 34, 35 and 36, is assigned to the support 29 and the lighting devices 28 fastened thereon. At least three such control lines are provided per carrier, for example carrier 29.
  • control lines can be used, for example seven control lines per carrier.
  • control device 37 is assigned to the support 30, the control device 38 to the support 31 and the control device 39 to the support 32. All control devices can be connected, for example, with the aid of the line 40
  • the lighting devices 28 can represent signal lamps and, for example, consist of diodes, for example those diodes from the Hewlett-Packard GmbH, Sales Center Germany,dorfberger Str. 110-130, D 71034 Böblingen, under the HLMP-XXXX series to be expelled.
  • control devices take into account a corresponding future offset of the associated upper knife 4 or 5 by Make the device glow, which is offset, for example, by this offset in relation to another lighting device provided per se. This displacement can be seen in the direction of arrow 21.
  • the control device 38 could be informed by how much the distance 16, which is located between the cutting edges 14 and 15, is from its nominal size due to the manufacturing process of the lower knife 8.
  • the lower knife 8 Since the lower knife 8 has a plurality of cutting edges, not to say many cutting edges, each of which should maintain the distance 16 from one another, it may be that a different distance 42 is very different from the intended dimension due to the production of the lower knife. Because of this diversity and the originally intended control, for example the lighting device 43, instead of the lighting device 43, the lighting device 44 can be controlled, for example, so that the operator is given the instruction: push the knife holder 18 for the new production not to the lighting device 43 that remains dark, but to the lighting device 44 that lights up instead. Analogously to this, the process of lighting up one or the other lighting device is corresponding to the respective width 26 of the spacer sleeve 22 or others Spacer sleeves or other corresponding spacer devices. The situation is similar when using several lower knives. Instead of, for example, five lighting devices per division of the respective lower knife, any other arbitrary number of lighting devices can be selected which is larger than one. This apparently simple increase in the number has many practical advantages for simple and quick operability of the device.
