Definitions

  • the present invention relates to an apparatus and method for introducing objects into a continuous flow of material.
  • the objects may be beads or capsules which are to be introduced into a continuous flow of filter material during manufacture of the filter component of a smoking article.
  • Smoking articles typically have a rod-shaped structure and include a charge, roll or column of smokable material such as cut tobacco.
  • the cut tobacco is typically surrounded by a paper wrapper thereby forming a so-called "tobacco rod".
  • a cylindrical filter element is aligned in an end-to-end relationship with the tobacco rod.
  • a filter element may comprise cellulose acetate tow filter material.
  • the filter material may be circumscribed by a paper material known as "plug wrap”.
  • the filter element is typically attached to one end of the tobacco rod using circumscribing wrapping material known as "tipping paper".
  • Various proposed methods for modifying the sensory attributes of smoke involve using filter elements as vehicles for adding additional flavour to the mainstream smoke in the smoking article. For example, it has been suggested to introduce objects such as capsules into the filter material during manufacture of the filter elements.
  • the apparatus described there comprises a reservoir containing the objects.
  • the reservoir opens out into a transfer chamber in which the objects are circulated.
  • the objects circulating in the transfer chamber move along a circulating path.
  • a part of the circulating path extends along the peripheral surface of a rotatable transfer wheel.
  • the rotatable transfer wheel has recesses (pockets) in its peripheral surface. The objects are introduced into and retained in the recesses with the aid of suction applied to the recesses.
  • a rotatable brush is arranged in the transfer chamber at the end of that part of the circulating path which extends along the peripheral surface of the transfer wheel.
  • an apparatus and method for introducing objects into a continuous flow of material While in the following specification only embodiments are illustrated in which objects are inserted into filter material, the invention also comprises cases in which the objects are inserted into other parts of a smoking article, for example into the tobacco rod or into a cavity in the filter.
  • the apparatus comprises a reservoir for providing a plurality of objects, a rotatable transfer wheel for transporting and delivering the objects to an insertion unit for introducing the objects into the continuous flow of material, and a transfer chamber for transferring the objects to the rotatable transfer wheel.
  • the transfer chamber is arranged between the reservoir and the rotatable transfer wheel.
  • the apparatus according to the invention further comprises means for generating a circulating movement of the objects in the transfer chamber such that the objects move along a circulating path. A part of the circulating path extends along the peripheral surface of the rotatable transfer wheel and in the direction of rotation of the rotatable transfer wheel.
  • the means for generating the circulating movement comprise a return member which is arranged in the transfer chamber at a curved side wall portion of the transfer chamber.
  • the return member is arranged at the end of that part of the circulating path which extends along the peripheral surface of the transfer wheel.
  • the return member and the curved side wall portion of the transfer chamber are arranged to reverse the direction of movement of the objects in the transfer chamber.
  • the return member has a drop-like shape comprising a peak, two straight flanks and a curved portion connecting the straight flanks. The peak faces towards the interior of the transfer chamber in a manner such that one of the flanks faces towards the peripheral surface of the rotatable transfer wheel, and this flank extends essentially tangential to the peripheral surface of the rotatable transfer wheel.
  • essentially tangential means that this straight flank and a tangent to the peripheral surface at the point where a normal to the peripheral surface goes through the peak of the return member, run parallel or include an angle which may amount up to 15 degrees.
  • the straight flank and the tangent include an angle.
  • the space between the straight flank and the peripheral surface tapers in a direction towards the end of that part of the circulating path that extends along the peripheral surface.
  • an object refers to any individual item that may be handled by the apparatus and method according to the invention.
  • the object is a substantially spherical object.
  • the substantially spherical object has a diameter of between about 0.5 mm and about 6.5 mm; more preferably, the substantially spherical object has a diameter of between about 2.5 mm and about 4.0 mm.
  • the substantially spherical object is a capsule.
  • the capsule comprises a liquid.
  • the liquid is flavorant, for example, menthol.
  • the capsule is crushable, that is, the capsule can release its content when a sufficient crushing strength is applied. With like objects, it is particularly important to handle the objects carefully as not to release the liquid within the capsules during the manufacturing process.
  • the use of the return member thus advantageously separates the capsules moving in a first direction, substantially along the periphery of the transfer wheel from the capsules moving into the opposite direction back into the transfer chamber after not having been picked up by the transfer wheel.
  • This separation allows for a better control of the speed of the capsules along the periphery of the transfer wheel. Further it reduces the stress onto the capsules, preventing breaking of capsules.
  • the rotatable transfer wheel may comprise recesses into which the objects are transferred through the application of suction to the bottom of the recesses.
  • an excess number of objects moves along the peripheral surface of the rotatable transfer wheel in order to make sure that each of the recesses of the rotatable transfer wheel contain exactly one object.
  • the objects enter into the space between the flank of the return member and the peripheral surface of the rotatable transfer wheel.
  • the return member facilitates the entering of one object into any empty recess so that each recess of the transfer wheel contains an object as the recess leaves the zone of the transfer chamber.
  • Those objects that have moved along the peripheral surface of the transfer wheel but have not been transferred to the rotatable transfer wheel are circulated back.
  • the direction of movement of the objects is reversed by the return member and the curved side wall portion of the transfer chamber. After having been circulated back, these objects can be used again for being transferred into the recesses of the rotatable transfer wheel.
  • circulating the objects in the transfer chamber advantageously prevents clogging.
  • the straight flank facing towards the peripheral surface of the rotatable transfer wheel is arranged at a predetermined distance from the peripheral surface of the rotatable transfer wheel.
  • This predetermined distance is selected such that a layer of one to six objects forms between the flank and the peripheral surface of the rotatable transfer wheel.
  • the predetermined distance may be selected such that a layer of from two to four objects forms between the flank and the peripheral surface of the rotatable transfer wheel.
  • This embodiment is advantageous in that it further contributes to the introduction of objects into the recesses in the peripheral surface of the rotatable transfer wheel, so that one object is retained in each recess of the rotatable transfer wheel as the respective recess leaves the zone of the transfer chamber.
  • the straight flank is arranged such that the space between the straight flank and the peripheral surface of the rotatable transfer wheel tapers.
  • this tapering of the space occurs in a direction towards the end of that part of the circulating path which extends along the peripheral surface of the rotatable transfer wheel.
  • a slight tapering of the space may assist in the transfer of objects into any potentially empty recesses of the rotatable transfer wheel.
  • the tapering should only be to an extent such that the objects do not get damaged or broken.
  • the tapering is of the magnitude of less that about a quarter of the diameter of a capsule.
  • the means for generating the circulating movement of the objects further comprise nozzles. These nozzles are arranged at the end of that part of the circulating path which extends along the peripheral surface of the rotatable transfer wheel.
  • the nozzles are capable of generating air flows which reverse the direction of movement of the objects in the transfer chamber. This reversal of movement of the objects is effected by the air flows together with the curved side wall portion of the transfer chamber, or together with the return member, or together with both the curved side wall portion and the return member.
  • the means for generating the circulating movement of the objects in the transfer chamber are designed such that, in operation, the speed of the objects along the peripheral surface of the rotatable transfer wheel is the same or substantially the same as the speed of the peripheral surface of the rotatable transfer wheel.
  • the term "substantially the same” with respect to the speed of the objects in particular means, that the speed of the objects along the peripheral surface of the rotatable transfer wheel is within a range of about 25 percent slower to about 25 percent faster than the speed of the peripheral surface of the rotatable transfer wheel.
  • the speed of the objects varies from the speed of the peripheral surface of the rotatable transfer wheel within a range of about 10 percent slower to about 10 percent faster than the speed of the peripheral surface of the rotatable transfer wheel. Whenever the term "about” is used in this application in connection with a specific value, this always is intended to also disclose the specific value. This may further improve the transfer of objects from the transfer chamber to the recesses of the rotatable transfer wheel.
  • Another aspect of the invention relates to a method for introducing objects into a continuous flow of material.
  • the method comprises the steps of:
  • the method further comprises the step of reversing the direction of movement of the objects in the transfer chamber by providing a return member.
  • the return member is arranged in the transfer chamber at a curved side wall portion of the transfer chamber, and at the end of that part of the circulating path which extends along the peripheral surface of the rotatable transfer wheel.
  • the method comprises the step of transferring the objects from the transfer chamber to the rotatable transfer wheel.
  • the rotatable transfer wheel transports the transferred objects to an insertion location where the objects are introduced into the continuous flow of material.
  • the return member has a drop-like shape, and comprises a peak, two straight flanks and a curved portion connecting the straight flanks.
  • the peak faces towards the interior of the transfer chamber.
  • the flank facing towards the peripheral surface of the rotatable transfer wheel extends essentially tangential to the peripheral surface of the rotatable transfer wheel.
  • the circulating movement of the objects in the transfer chamber is generated such that the speed of the objects moving along the peripheral surface of the rotatable transfer wheel is the same or substantially the same as the speed of the peripheral surface of the rotatable transfer wheel.
  • the speed of the objects may vary from the speed of the peripheral surface of the rotatable transfer wheel such that the speed of the objects is within a range of about 25 percent slower to about 25 percent faster than the speed of the peripheral surface of the rotatable transfer wheel.
  • the speed of the objects is such that the speed of the objects is within a range of about 10 percent slower to about 10 percent faster than the speed of the peripheral surface of the rotatable transfer wheel.
  • the step of reversing the direction of movement of the objects in the transfer chamber further comprises providing additional air flow at that end of the circulating path which extends along the peripheral surface of the rotatable transfer wheel.
  • the additional air flow is such that it reverses the direction of movement of the objects in the transfer chamber, either together with the curved side wall portion of the transfer chamber, or together with the return member, or together with both the curved side wall portion and the return member.
  • FIG. 1 a perspective view of an embodiment of essential components of the apparatus according to the invention are shown in an assembled state.
  • Fig. 2 shows a front view of this embodiment disclosing some additional details.
  • the apparatus comprises a reservoir 1 where the objects, for example capsules , are provided.
  • a non-transparent front plate 10 of reservoir 1 can be seen in Fig. 1 while in Fig. 2 front plate 10 is shown to be transparent so that additional details of the apparatus are visible.
  • the apparatus further comprises a transfer chamber 2 which is arranged between reservoir 1 and a rotatable transfer wheel 3.
  • a return member 20 having a drop-like shape is arranged in transfer chamber 2. Return member 20 helps to reverse the movement of the capsules along the periphery of rotatable transfer wheel 3 in transfer chamber 20, as will be discussed in more detail further below.
  • a number of nozzles 100 are arranged in front wall 10. With the aid of nozzles 100, overpressure or suction can be applied in order to create a circulating movement of the capsules in transfer chamber 2. This is indicated in Fig. 2 by the arrows in transfer chamber 2. Also, the overpressure or suction applied through nozzles 100 assists the capsules in getting moved towards rotatable transfer wheel 3.
  • Transfer chamber 2 is formed between a rear wall 11 and front wall 10. The depth of transfer chamber 2 between front wall 10 and rear wall 11 is such that only a single layer of capsules is allowed to form. By way of example, the depth (“thickness") of transfer chamber 2 may be in a range of about 110 percent to about 120 percent of the outer dimensions of the capsules.
  • Additional nozzles may be arranged in rear wall 11 in a position similar to the position of nozzles 100 in front wall 10. Through these additional nozzles overpressure or suction can be applied in a similar manner as through nozzles 100, in order to create the circulating movement of the capsules in the transfer chamber 2. This further assists in movement of the capsules towards rotatable transfer wheel 3.
  • the capsules are sucked into recesses provided in the peripheral surface of rotatable transfer wheel 3 (the recesses not being visible in Fig. 1 and Fig. 2 ). This can be performed by applying suction through the bottom of the individual recesses provided in rotatable transfer wheel 3.
  • Each capsule is retained in the respective recess until the capsule is introduced into a continuous flow of material at a unit for introducing the capsules into the continuous flow of material.
  • the unit for introducing the capsules into the flow of material is not shown in the drawings and may be a conventional unit which is well-known in the art.
  • a suitable unit for introducing the capsules into a continuous flow of filter tow is shown in Figs. 10-12 of WO 2010/055120 and is described in detail in the corresponding parts of the specification thereof.
  • the disclosure related to this unit for introducing the capsules into the continuous flow of filter material is therefore incorporated herein by reference.
  • the capsules are released from the recesses and introduced into the continuous flow of filter tow when the respective recess of the rotatable transfer wheel is at the lowermost position.
  • a detail of transfer chamber 2 is represented showing return member 20 in more detail.
  • Return member 20 is arranged in transfer chamber 2 at the end of that part of the circulating path of the capsules which extends along the peripheral surface of rotatable transfer wheel 3.
  • Return member 20 has a drop-like shape comprising a peak 200, two straight flanks 201, and a curved portion 202 connecting the two straight flanks 201.
  • Peak 200 faces towards the interior of transfer chamber 2.
  • That flank 201 which faces towards the peripheral surface of rotatable transfer wheel 3 extends essentially tangential to the peripheral surface of rotatable transfer wheel 3 so as to allow the capsules to flow around return member 20.
  • return member 20 assists in reversing the direction of movement of the capsules in transfer chamber 2.
  • Flank 201 of return member 20 facing towards the peripheral surface of rotatable transfer wheel 3 is arranged at a predetermined distance 204 from the peripheral surface of rotatable transfer wheel 3 (the peripheral surface of rotatable transfer wheel being indicated by dashed lines).
  • Predetermined distance 204 is selected such that a layer of one to six capsules may form between flank 201 and the peripheral surface of rotatable transfer wheel 3.
  • predetermined distance 204 can be selected such that a layer of from two to four capsules may form between flank 201 and the peripheral surface of rotatable transfer wheel 3.
  • Return member 20 may be arranged such that the space between flank 201 and the peripheral surface of rotatable transfer wheel 3 tapers slightly.
  • the space tapers in the direction towards the end of that part of the circulating path which extends along the peripheral surface of rotatable transfer wheel 3. This may cause a slight pressure on the capsules as they move through this space. This slight pressure may assist the insertion of the capsules into the recesses of rotatable transfer wheel 3.
  • the tapering preferably is be selected such that the slight "pressure" produced through the said tapering cannot cause any damage or breaking of the capsules.
  • one or more nozzles 203 may be arranged at the end of the circulating path of the capsules along the peripheral surface of rotatable transfer wheel 3. Nozzles 203 are capable of generating air flows which reverse the direction of movement of the capsules in transfer chamber 2, together with either the curved side wall of transfer chamber 2, or together with return member 20, or together with both the curved side wall and return member 20, as this is indicated by the arrows represented in Fig. 3 .
  • reservoir 1 is filled with capsules which enter into transfer chamber 2 at the lower end of reservoir 1 (see Fig. 1 ).
  • transfer chamber 2 a circulating movement of the capsules is generated, as is indicated by the arrows in Fig. 2 .
  • the capsules move along the peripheral surface of rotatable transfer wheel 3.
  • Each of the recesses of rotatable transfer wheel 3 is filled with a capsule or bead due to suction being applied to the bottom of the respective recess.
  • Those capsules not sucked into a recess are returned along the circulating path indicated by the arrows in Fig. 2 with the aid of return member 20 and nozzles 203.
  • Those capsules sucked into a recess are transported by rotatable transfer wheel 3 to a unit for introducing the capsules into a continuous flow of filter material. There, the capsules are released from the recesses and introduced into the flow of filter material as this is described in detail in WO 2010/055120 .
  • the respective empty recess again reaches the zone of transfer chamber 2 where a capsule or bead is sucked into the recess again, as this is described above.
  • the capsules are moving along the peripheral surface of rotatable transfer wheel 3 with a speed which is the same or substantially the same as the speed of the peripheral surface of rotatable transfer wheel 3.
  • the speed of the capsules along the peripheral surface of rotatable transfer wheel 3 is within a range of about 25 percent slower to about 25 percent faster than the speed of the peripheral surface of rotatable transfer wheel 3. More preferably, the speed of the capsules is within a range of about 10 percent slower to about 10 percent faster than the speed of the peripheral surface of rotatable transfer wheel 3.
  • a speed of movement of the capsules which is the same or substantially the same as the speed of the peripheral surface of rotatable transfer wheel 3 is advantageous in that it further improves the transfer of capsules from transfer chamber 2 to the recesses of rotatable transfer wheel 3.
