Definitions

  • This invention relates to a cutting head for cutting rod-shaped pieces in machines for making smokers' articles.
  • rod-shaped piece preferably includes pieces of filter or cigarette processed prior to obtaining a finished cigarette.
  • the cutting head of this invention can be applied to a filter tip attachment machine in cigarette making machine, where pieces of filter are applied to corresponding pieces of cigarette.
  • the cutting head of this invention can be advantageously applied to cutting composite filters of the type which are externally covered by an impermeable plastic sheath ("filter tube").
  • Prior art cutting heads as described for example in DE 10 2009 047 022 A comprise a circular blade made of metallic material.
  • the blade cyclically severs a double-length piece of filter or cigarette, dividing it into two single-length pieces.
  • Filter tip attachment machines comprise feed drums for feeding double length pieces of cigarette which are each divided into two single length pieces by a first circular cutting blade.
  • the two pieces of cigarette thus obtained are axially spaced by a spacing drum and, in a drum following that, a double-length piece of filter is inserted between them and joined to the pieces of cigarette by wrapping in a sheet of paper material.
  • the double-length piece of filter is then cut into two in a yet further drum by another circular cutting blade in such a way as to obtain two cigarettes placed end to end with their filter tips.
  • the blade is subject to heating which interacts negatively with the filter material which tends to stick to the surface of the blade, especially on the peripheral zone of it defining the cutting edge.
  • Repeated cutting causes the filter material to build up on the blade, reducing the cutting properties of the blade and thus worsening the quality of the cut pieces of filter.
  • the basic technical purpose of this invention is to provide a cutting head for cutting rod-shaped pieces in machines for making smokers' articles to overcome the above mentioned disadvantages of the prior art.
  • this invention has for an aim to provide a cutting head for cutting rod-shaped pieces in machines for making smokers' articles which is capable of guaranteeing lasting high cutting quality by eliminating the problem of rapid wear.
  • the numeral 1 denotes in its entirety a cutting head for cutting rod-shaped pieces in machines for making smokers' articles according to this invention.
  • the cutting head 1 comprises a circular blade 2 mounted on a supporting frame 3 and driven in rotation about its axis "X" by drive means which, for example, comprise a motor (not illustrated) inside the supporting frame 3 or other means for connecting it to drive means (not illustrated).
  • drive means which, for example, comprise a motor (not illustrated) inside the supporting frame 3 or other means for connecting it to drive means (not illustrated).
  • the cutting head 1 shown in the accompanying drawings with some parts cut away in order to better illustrate the invention, is preferably located at a filter tip attachment machine where pieces of filter are attached to pieces of cigarette. More in detail, the cutting head 1 is adapted to operate on rod-shaped articles (not illustrated in the accompanying drawings) transported in the suction flutes of a drum transversely to the axis of extension of the rod-shaped articles themselves. In this situation, the cutting head 1 is positioned with the circular blade 2 oriented with its axis "X" parallel to the axis of the rotary drum and thus parallel to the axis of the rod-shaped articles so that the position plane of the circular blade 2 is perpendicular to the rod-shaped articles, enabling the circular blade 2 to cut the articles into two parts.
  • the circular blade 2 is located at the end of a substantially tubular portion 3a of the supporting frame 3, aligned with the axis "X" of the circular blade 2.
  • the circular blade 2 which is of essentially known type, is defined by a metallic disc which is substantially flat except for an outer circular crown defining a cutting portion 4 which is tapered towards the cutting edge 5 in such a way as to define a rake angle "S" relative to the flat front surfaces of the circular blade 2 ( Figure 8 ).
  • the rake angle "S" is between 2° and 40°.
  • the cutting head 1 comprises scraping means 6 which are at least temporarily in contact with the cutting portion 4 of the circular blade 2 during a working cycle of the blade 2 in order to mechanically remove any residues from the cutting portion 4.
  • the scraping means 6 comprise at least one scraping disc 7 rotatable about a respective axis of rotation "Y1" and having a peripheral portion which is kept in contact with the cutting portion 4 of the circular blade 2.
  • the scraping means 6 comprise a pair of scraping discs 7, 8 disposed on opposite faces of the cutting portion 4 of the circular blade 2 so that any residues are removed from both sides of the cutting portion 4.
  • the two scraping discs 7, 8 have respective axes of rotation "Y1", “Y2" which are inclined in opposite directions, and still more preferably by the same quantity, relative to the axis of rotation "X" of the circular blade 2.
  • each scraping disc 7, 8 is inclined relative to the axis of rotation "X" of the circular blade 2 in such a way that the scraping disc 7, 8 can be kept in contact with the cutting portion of the circular blade along a contact line belonging to the cutting portion.
  • the axis of rotation "Y1", “Y2" of each scraping disc 7, 8 is inclined relative to the axis of rotation "X" of the circular blade 2 at an angle of between 2° and 40°.
  • the axes of rotation "Y1", "Y2" of the scraping discs 7, 8 are skew to each other.
  • each scraping disc 7, 8 in the zone of contact with the cutting portion 4 of the circular blade 2, each scraping disc 7, 8 is contained in a plane which is inclined oppositely to the rake angle relative to the plane containing the circular blade 2.
  • each scraping disc acts on an annular band of the cutting portion 4 whose radial extension is between 0.2 and 10 mm.
  • each scraping disc 7 is idle and is driven in rotation about its axis "Y1" by frictional interaction with the circular blade 2.
  • the frictional interaction between the circular blade 2 and the scraping discs 7, 8 is only partly tangential and also has a radial component. The tangential components drive the scraping discs 7, 8 in rotation, while the radial components produce the scraping action on the cutting portion 4.
  • the scraping means 6 are mounted on a supporting member 9 which is designed to adopt an adjustable position relative to the circular blade 2, in particular according to a translational movement towards and away from it.
  • a supporting member 9 which is designed to adopt an adjustable position relative to the circular blade 2, in particular according to a translational movement towards and away from it.
  • This is accomplished by mounting the supporting member 9 on the frame 3 by means of a stem 10 which can be driven with precision using a micrometric screw 11. That way, it is possible to compensate for any clearances between the scraping means 6 and the circular blade 2 as a result of wear.
  • the supporting member 9 is a rigid, cradle-shaped element which supports the two scraping discs 7, 8 on each side of it and which is connected, centrally, at the bottom of it to the upper end of the stem 10, whose lower end is coupled to the frame 3 and is connected to the aforementioned micrometric screw 11.
  • the cutting head 1 also comprises a blowing member 12 acting on at least one face of the circular blade 2 to direct a cooling air jet at the circular blade 2 and, in particular at least at the cutting portion 4 of the circular blade 2.
  • the blowing member is configured in such a way as to direct a cooling air flow at both faces of the circular blade 2.
  • the blowing member 12 is a U-shaped element having a central housing which receives a peripheral part of the circular blade 2 whose peripheral part is thus enclosed in the blowing member 12.
  • the peripheral part of the circular blade 2 acted on by the blowing member 12 extends in a radial direction from the cutting edge 5 for between 0.2 and 10 mm.
  • the blowing member 12 is also mounted to the supporting member 9 and, in order to supply compressed air to the blowing member 12, at least one pneumatic fitting 13 is provided for connection to a compressed air supply hose (not illustrated).
  • the blowing member 12 is operatively located upstream of at least one of the scraping means 6 (that is, of at least one of the scraping discs 7, 8).
  • the scraping means 6 are operatively located at least partly downstream of the blowing member 12.
  • blowing member 12 is located at an intermediate position between the two scraping discs 7, 8.
  • the cutting head 1 may also comprise at least one auxiliary scraping member 14 operatively positioned substantially in contact with at least one face of the circular blade 2 further on the inner side of the cutting portion 4 and adjacent to the cutting portion 4.
  • the auxiliary scraping members 14 act on a different annular zone of the circular blade 2 from that acted upon by the scraping means 6, in particular on a zone in which the faces of the circular blade 2 are parallel to each other and perpendicular to the axis of rotation "X" (that is to say, further in than the cutting portion 4 with the rake angle "S").
  • Each auxiliary scraping member 14 thus has a scraping edge which is preferably rectilinear and parallel to the plane defined by the respective face of the circular blade 2 it acts on.
  • the auxiliary scraping members 14 are located upstream of the two scraping discs 7, 8 relative to the feed direction of the circular blade 2, that is to say, at a position between the cutting area (labelled "A" in Figure 1 and corresponding to the zone in which the circular blade 2 cuts the rod-shaped articles) and the scraping discs 7, 8.
  • the width of the annular band of the circular blade 2 acted on by the auxiliary scraping members 14 substantially coincides with the annular band acted on by the blowing member 12.
  • auxiliary scraping members 14 are mounted on a fixed part of the cutting head, in particular on the frame 3, and are therefore not applied to the adjustable supporting member 9.
  • the auxiliary scraping members 14 are of adjustable type: in particular, they can be moved towards and away from the faces of the circular blade 2 by tilting about respective hinge axes "Z1", "Z2" in order to vary the distance between them and the circular blade 2 and/or to enable or disable their scraping action.
  • the cutting head 1 also comprises protective elements to cover at least part of the working zone of the circular blade 2. More specifically, the protective elements, shown in Figure 1 , comprise a face guard 15 covering the zone of interaction between the scraping discs 7, 8 and the circular blade 2 and/or curved protective guards 16 placed around the scraping discs 7, 8. Variants of the invention described in the foregoing are also imaginable without departing from the scope of the inventive concept. In particular, there may be a different number of scraping discs, mounted as required at suitable positions relative to the circular blade.
  • the parts of the circular blade acted on by the auxiliary scraping members and/or the blowing member may also differ from each other and from what is described above.
  • This invention achieves the preset aim thanks to the distinctive interaction between the action of the scraping discs to remove the residues and the cooling effect of the blowing member on the circular blade, which combine to improve blade cleaning efficiency, thereby increasing blade working life without requiring frequent maintenance to clean or change the blade and with obvious advantages in terms of productivity.
  • This effect is particularly important for cutting plastic covered filters because it avoids the build-up of molten plastic residues resulting from the cutting action.
