Definitions

  • This invention relates to an abutment unit for pieces of smokers' articles, usable preferably in machines used for making composite filters and commonly known as combiners.
  • Combiners of known type comprise one or more abutment units for pieces of smokers' articles, in particular pieces of filter, which this specification expressly refers to but without losing in generality, and which essentially comprise a rotary abutment drum equipped on its outer surface with a plurality of suction flutes extending along an axis parallel to the axis of rotation of the drum.
  • Separate pieces - for example three - of filter material or the like are placed in the flutes with their axis parallel to the axis of the flute in such a way as to form what is known as a filter plug, substantially cylindrical in shape.
  • a filter plug consisting of three pieces is made from a first piece which is cut into two parts which are in turn spaced from each other in an axial direction, generally by movement of respective flutes in which they are held. The two parts or pieces thus obtained and spaced from each other are transferred into the flutes of the abutment drum and a third piece is placed between the preceding two.
  • the three pieces thus positioned are brought into abutment along an axial direction as the abutment drum rotates and are then joined to each other, for example by means of an outer wrap.
  • the plugs thus obtained are then used in subsequent conventional processing steps.
  • the flutes on the drum may be continuous or discrete, that is, divided into a succession of separate parts, in some cases, separated by empty spaces, each preferably intended to receive a corresponding piece of the plug.
  • the separate pieces are brought into abutment by means of pushing systems which push the free axial ends of the plugs located at the ends of the respective flutes and protruding axially therefrom.
  • pushing systems comprise, for example, pushing discs positioned at the bases of the drum and suitably shaped in such a way that a respective outer circular crown strikes corresponding ends of the plugs as the drum rotates so as to push the pieces towards each other.
  • the separate pieces which make up each filter plug may differ in length according to the final filter to be made.
  • the size of the filter plugs is variable between a maximum value and a minimum value based on the type of filter to be made.
  • the length of the filters and hence of the filter plug is usually adjusted by modifying the length of the first piece which is divided in two.
  • Varying the length of this piece creates the drawback of having to substitute the abutment drum so that the total axial length of the flutes is always considerably less than that of the plugs so the pushing systems can bring the separate pieces into abutment and reach, as their maximum limit, the axial ends of the flutes.
  • Varying the size of the filters being made also creates the drawback of having to substitute the movement system - for example, a cam - which widens the flutes for receiving the two distinct parts into which the first piece is divided, since the distance between these parts must allow the third piece to be placed between them.
  • the main purpose of this invention is to propose an abutment unit for pieces of smokers' articles to overcome the above mentioned drawbacks.
  • This invention has for an aim to provide an abutment unit for pieces of smokers' articles which is more versatile than prior art solutions and which allows changeovers to be managed more easily without shutting down the machine in which the unit is installed or considerably reducing the down times.
  • the numeral 1 denotes an abutment unit for pieces 100a, 100b, 100c of smokers' articles which, for simplicity, are shown only in Figure 2 .
  • the pieces 100a, 100b, 100c, each of which has a main axis, are usually cylindrical in shape and, hereinafter, preferred reference is made to pieces of filter or of filter material.
  • the unit 1 is intended for the tobacco industry and, preferably, is intended for a machine which makes composite filters, also known as "combiner” and schematically indicated by the reference numeral 200.
  • the machine 200 is of substantially known type and is not described in detail.
  • the unit 1 comprises an abutment drum 2 rotatable about an axis of rotation R.
  • axial is used to denote directions parallel to the axis of rotation R
  • radial is used to denote directions parallel to a radius of the drum 2.
  • the drum 2 comprises, on its outside cylindrical surface, a plurality of suction flutes 3 for holding down the pieces of smokers' articles and extending mainly in a direction parallel to the axis of rotation R.
  • Each flute 3 has a first end 3a and a second end 3b.
  • Each flute 3 preferably defined as a portion of a cylindrical surface whose axis is parallel to the axis of rotation R of the drum, is shaped to match a portion of the outside cylindrical surface of the pieces of smokers' article and is delimited by respective flanks 4.
  • Each flank 4 delimits, in a substantially known manner, two consecutive flutes 3 along the outside cylindrical surface of the drum 2.
  • Each flank 4 has an outside radial profile.
  • a succession of outside profiles of the flanks 4 defines an outside cylindrical surface having an axis R.
  • the unit 1 comprises pusher means (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20) operating at the abutment drum 2 to push the pieces 100a, 100b, 100c towards each other from a spaced-apart position to a close-together position.
  • pusher means (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20) operating at the abutment drum 2 to push the pieces 100a, 100b, 100c towards each other from a spaced-apart position to a close-together position.
  • the pieces 100a, 100b, 100c are abutted end to end along a longitudinal direction to form a plug 101, shown in Figure 2 .
  • the pieces 100a, 100b, 100c are movable in the respective flute 3 along an abutment direction parallel to the axis of rotation R and substantially parallel to the main axis of the pieces 100a, 100b, 100c themselves.
  • the pusher means comprise engagement means 7, 8, 9, 10 by which the pieces fed into the flutes 3 of the drum 2 are engaged.
  • the engagement means 7, 8, 9, 10 by which the pieces 100a, 100c are engaged are at least partly movable along the abutment direction between an away position spaced from the abutment drum 2, shown at the top of Figure 2 , substantially at a station 300 where the pieces are loaded, and a near position close to the abutment drum 2, shown in Figure 2 .
  • the engagement means 7, 8, 9, 10 project at least partly beyond a radial dimension of the flanks 4.
  • the engagement means 7, 8, 9, 10 are shaped to be able to act on the pieces by projecting beyond the radial dimension of the flanks 4.

  • the portions 5b, 6b are configured to be deformed along the abutment direction parallel to the axis R so as to allow the engagement means to move between the near position and the away position.
  • the actuating means operate on the first disc-shaped element 5 - in particular on the annular portion 5b thereof - and on the second disc-shaped element 6 - in particular on the annular portion 6b thereof - in order to move the engagement means between the near position and the away position by elastically deforming the disc-shaped elements 5 and 6.
  • the positions near the drum 2 and away from the drum 2 of the engagement means correspond to a position where the portions 5b, 6b are close together and a position where the portions 5b, 6b are spaced apart.
  • the engagement means for engaging the pieces 100a, 100b, 100c comprise a first annular tooth 7 and a second annular tooth 8.
  • the tooth 7 extends from the external annular portion 5b of the element 5 towards the drum 2.

  • the faces 7a, 8a extend radially and are shaped to engage part of one end of the corresponding piece.
  • the teeth 7, 8 act on a radially outer portion of the pieces 100a, 100c, in particular, the portion of the pieces which extends radially beyond the dimensions of the flanks 4.

  • the faces 9a, 10a are shaped to engage the whole of the end surface of the corresponding piece, that is, they have substantially the same shape as the transversal cross section of the pieces to be moved.
  • this solution allows abutting filter pieces 100a, 100b, 100c even if made of delicate material since the pushing pressure is, in use, distributed over the entire base area of each piece.
  • the faces 9a and 10a of the pusher means 9, 10 are positioned at an axial distance which is smaller than the maximum axial dimension of the drum 2 and in particular than a maximum axial dimension of the flanks 4.

  • the rollers 11, 12 have respective axes of rotation R1, R2, preferably transversal to each other and preferably intersecting the axis of rotation R of the drum 2.
  • the rollers 11, 12 are spaced from each other along a circular arc so as to maintain the action of the pusher means on the pieces for a predetermined length of time before the plugs 101 are discharged, in substantially known manner.

  • the distance between the faces 7a and 8a or between the faces 9a and 10a with the portions 5b, 6b in the near position corresponds, in practice, to the length of the plug 101 or to the sum of the lengths of the pieces 100a, 100b and 100c in abutment against each other along the respective flute 3.
  • the axial distance between the faces 7a and 8a or between the faces 9a and 10a may be greater than, smaller than or equal to the axial measurement of the drum 2 or, more specifically, of the flanks 4 as a function of the length of the pieces 100a, 100b, 100c being processed.
  • the pieces 100a, 100b, 100c are positioned in the flutes 3 spaced from each other at the loading station 300.
  • the rotation of the portions 5b and 6b is opposed by the rollers 11, 12 and 14, 15, respectively.
  • rollers 11, 12 and 14, 15 during the rotation of the drum 2 causes bending, substantially along the abutment direction, of the portion 5b and of the portion 6b, respectively.
  • the bending of the portions 5b and 6b causes the engagement means to move to the near position, that is to say, the teeth 7, 8 or the pusher means 9, 10 move towards each other, thereby pushing the pieces 100a, and 100c and compacting the plug 101.
  • the preferred arrangement of the pusher means 9, 10 and/or the preferred shape of the teeth 7, 8 make it possible to compact even plugs 101 whose length, measured along the abutment direction, is less than the length of the flutes 3 or of the flanks 4.
  • the combiner 200 equipped with the abutment unit 1 is structured as if it always worked pieces or filters of the largest size. Spacing systems, if any, for the pieces upstream of the abutment unit remain configured to space the end pieces by the maximum distance, irrespective of the axial size of the middle piece interposed between them.
  • the abutment drum always has flutes of the maximum length because the pusher means are able to compact even plugs whose total length is less than the axial length of the flutes or flute flanks.
  • the abutment unit according to this invention advantageously allows changeovers to be carried out without having to substitute mechanical units since it is sufficient to adjust using the mechanism 20.
  • the abutment unit according to the invention eliminates the need for service or substitution of mechanical parts during changeovers.
  • the abutment drum, or the respective flutes, is of the axial width suitable for plugs of the largest size. Similarly, all the rollers and mechanisms upstream are for plugs of the largest size even when operating on plugs of smaller size.
