Definitions

  • the proposed invention relates to the technical Field of changing the position of knives according to the preamble of the appended claim 1.
  • Facilities of the type mentioned, for example used to use relatively wide webs at least with the help one - usually with the help of several - slitter cut into narrow strips, so that these narrow strips then, for example smaller rolls can be wound up Setup is, for example, from the German patent 41 07 227 known.
  • traverse for example provided, that is a transverse to the direction of the machining path arranged connection between two Frame parts, for example of two side walls, the is shaped so that several knives are held on it can.
  • the knives are able to move the web in the direction of travel to cut so that the said narrower Strips can be cut out of this path, often there are several knives in such cutting devices distributed over the width of the web to be cut. These knives can be changed in position thus to enable that, depending on the request, different widths Strips can be cut.
  • Each one for one Cutting process required knife works with an appropriate Counter knife together. For example, works an upper knife with a lower knife. So that Adjustment can be carried out relatively easily, d. H., that relatively easy to cut by a width of Stripes can be switched to another often used as counter knife so-called lower knife, which contain several intersecting surfaces, each suitable are to work with an upper knife in the desired sense.
  • the individual To produce parts of the cutting device as inexpensively as possible.
  • the or the respective lower knife, with which a so-called upper knife cooperates, manufactured as inexpensively as possible must become.
  • the bottom knife has been designed so that it is, for example, across the entire width of the processing web in one piece and regular Spacing contains cutting edges.
  • the known Lower knife shows a variety of such cutting edges, that have to be at a certain distance from each other, if possible the widths of the strips to be achieved should be strictly observed. This means that a large number of tolerances must be observed when the lower knife in question is manufactured. The accuracy requirements in manufacturing of course make the product more expensive, in this case the lower knife.
  • This machine Facility contains u. a. so-called upper knife 4 and 5, and Lower knives 6, 7, 8 and 9.
  • Each lower knife has one Variety of cutting edges, for example the cutting edges 10, 11, 12.
  • Two cutting edges each of a lower knife close a mutual distance, the so-called division on.
  • the cutting edges 14 and 15 close, for example the distance 16 between each other, which in the experts as a division between the cutting edges 14 and 15 is referred to.
  • Each of the upper knives 4 and 5 can be used interact with every desired cutting edge.
  • each of the upper knives can be rotated in a so-called holder 17 or 18 held and attached to it.
  • Each holder 17 or 18 or other such holders can be along a rail 19 moved or moved and fixed to this in the professional world, this rail is usually used as a traverse referred to as.
  • the rail is on its end faces attached to the associated machine frame, moves therefore not itself.
  • the holders 17 and 18 of the upper knife 4 and 5 are also designed so that they are before moving the holder 17 and 18 initially opposite the rail so that the knives from the Cutting edges 11 to 12 etc.
  • the respective lower knife free, so to speak from the so-called cutting grooves 20 of the respective lower knife can swap out before the holder 17 and 18 are moved in the direction of arrow 21 can, so that the respective upper knife with another Cutting edge than before for another cutting job can work together.
  • Between the respective lower knives can insert spacers or something similar become.
  • the spacer sleeve 22 is between the lower knives 6 and 7 inserted, the spacer sleeve 23 between the lower knives 7 and 8. All lower knives and Spacer sleeves are pushed onto a shaft 24, whereby the shaft 24 in a known and therefore not shown again Way rotatable in the corresponding machine frame is stored.
  • the shaft 24 with be provided with a rotary drive.
  • spacer sleeve Between the lower knives 8 and 9 is, for example, not such a spacer sleeve used. However, it is also possible here to use a spacer sleeve or use something similar. Such spacers can also be viewed as spacers or have a crescent-shaped cross-section, so that they roughly represent an open Latin C. If if this is the case, then it is not necessary about that Remove the lower knife 6, 7, 8 and 9 from the shaft 24, when the spacers 22 and 23 are changed, for example should be. It is sufficient to use the lower knives 6 to 9 which are in usually screwed onto the shaft 24 to loosen, so that they are slightly parallel in the direction of arrow 25 be shifted to the geometric axis of the shaft 24 can.
  • the width becomes 26 the spacer sleeve 22 or a corresponding spacer plate or spacer another.
  • the width 26 of each selected spacer sleeve or the corresponding spacer does not necessarily have the distance 13, which between two cutting edges of the lower knife.
  • the width 26 can be quite different from that Distance 13.
  • the lower knives 6 to 9, etc. are manufactured and are therefore necessarily subject a corresponding accuracy that is due to the manufacturing process is conditional. This accuracy is said to be be that it does not make the individual lower knife unnecessarily expensive. Inexpensive manufacture, however, requires relative rough tolerances so that it can occur, for example can that the distance 13 is not necessarily the distance 16 must be the same. This applies all the longer the longer it is selected lower knife is d. H. the wider it gets in the figure.
  • lighting devices are 28 in Form of signal lamps or the like. Provided so that the operator can find the position very quickly, where the respective holder of the respective knife is positioned must become.
  • These signal lamps are in turn Direction of arrow 25 or parallel to it or parallel to the direction of arrow 21 on the rail 19 in such a way attached that such a signal lamp next to the other lies.
  • Two signal lamps hold one below the other a distance 27 which is significantly smaller than, for example the distance 13 or the distance 16. For example there are five such signal lamps or lighting devices to the width of a distance 13 or 16. Thus the distance 27 is smaller than the division of the associated one Lower knife, for example a fifth or a Quarter, but maximum half of the distance 13 or of the distance 16.
  • Lighting devices 28 are arranged on a support 29, for example in powers of two such as 128 or 256.
  • Several Beams 29, 30, 31 and 32 are along the rail 19 attached to her or an associated part, which means that the carriers 29 to 32 are arranged side by side in the figure appear.
  • the carrier 29 and the attached Lighting devices 28 is a control device 33 assigned, which by means of control lines 34, 35 and 36 is connected to the carrier 29. At least three of them Control lines are per carrier, for example the carrier 29 provided.
  • Control lines there can be a different number of Control lines are used, for example seven Control lines per carrier.
  • the carrier 30 is in a corresponding Assigned the control device 37, the carrier 31 is the control device 38 and the carrier 32 the control device 39. All control devices can for example with the help of line 40 with a Central control device 41 may be connected.
  • the lighting devices 28 can represent signal lamps and, for example consist of diodes, for example such diodes, which from Hewlett-Packard GmbH, sales center Germany,iereberger Str. 110-130, D 71034 Böblingen, are sold under the HLMP-XXXX series.
  • widths 26 of the spacer sleeve 22 or similar devices the respective control device or the central control device 41 before the start of the production process have already been notified, take into account these control facilities a corresponding future offset of the associated upper knife 4 or 5 by adding a lighting device to shine, which for example this offset from another in itself beforehand provided lighting device is offset.
  • This Dislocation can be seen in the direction of arrow 21.
  • controller 38 could be communicated to controller 38 by how much the distance 16, which is between the cutting edges 14 and 15 is due to the manufacturing process of the lower knife 8 from its nominal size is removed.
  • each one should keep the distance 16 between them, it may be that a different distance 42 due to the manufacture of the The lower knife is very different from that intended for it Target dimension.
  • the lighting device 43 for example instead of the lighting device 43 the lighting device 44 can be controlled, so that the operator is informed: slide the knife holder 18 for the new production process not on the dark lighting device 43, but instead of the luminous lighting device instead 44.
  • the process of lighting up is analogous to this corresponding to one or the other lighting device the respective width 26 of the spacer sleeve 22 or others Spacer sleeves or other corresponding spacing devices. Similar relationships also result in the use of several lower knives. Instead of, for example five lighting devices per division of each Lower knife can also be any other Number of lighting devices can be selected, which larger than one. This seemingly simple enlargement The number has many practical advantages for a simple one and quick usability of the facility.
