Definitions

  • the present invention relates to an apparatus for introducing solid objects into a material flow.
  • the solid objects may be capsules or beads.
  • US-A-2005/0070409 discloses an apparatus wherein capsules are transferred from a reservoir to a central portion of a rotating horizontal pan. Through rotation of the horizontal pan the capsules are transported to the peripheral portion of the pan. At the peripheral portion of the pan stem lifters are arranged lifting the capsules from the pan up and transferring them into transfer tubes arranged at the periphery of the horizontal pan. The capsules are then further transported through the transfer tubes to a rotating vertical wheel comprising pockets with seats for receiving the capsules. The capsules received in the seats are then transported through rotation of the vertical wheel to an insertion location where the capsules are deposited into a stream of filter material.
  • an apparatus for introducing solid objects into a material flow of for example a smoking article While in the following specification only embodiments are discussed in which solid objects are inserted into filter material, the invention is applicable for the insertion of solid objects into other parts of a smoking article, for example into the tobacco rod or into a cavity of the smoking article.
  • an apparatus comprising a first wheel being arranged to be rotatable about a vertical axis and being capable of transporting the solid objects to a peripheral portion of the first wheel.
  • the apparatus according to the invention further comprises a second wheel mounted beneath the peripheral portion of the first wheel at a transfer location, the second wheel being arranged to be rotatable about a horizontal axis and comprising recesses for receiving the solid objects provided by the first wheel at the transfer location.
  • the apparatus according to the invention further comprises at least one ejector pin, the at least one ejector pin being slidably arranged between an upper position, in which a solid object may be transported to a location beneath the ejector pin, and a lower position, such that movement of the ejector pin from the upper position to the lower position pushes a solid object from beneath the ejector pin into the recess of the second wheel at the transfer location.
  • the second wheel is further capable of transporting and delivering the solid objects received in the recesses to a unit for introducing the solid objects into filter material.
  • the ejector pin provides for a very fast and reliable mechanical transfer of a solid object from the first to the second wheel through a pushing action.
  • the ejector pin as an active transfer means contributes significantly to the movement of the solid objects which are otherwise acted upon by gravitational forces only. Due to centrifugal forces acting on the solid objects during operation of the first wheel, the gravitational forces are further reduced by frictional forces on the outer perimeter of the first wheel. Accordingly, the use of the ejector pin to support the gravitational forces in the transfer of the solid objects from the first wheel to the second wheel becomes even more advantageous at higher machine speed.
  • the ejector pin also provides for a well-defined guided movement of the solid objects which are to be securely transferred into the recesses of the second wheel.
  • the ejector pin when the ejector pin is in the lower position it prevents following solid objects, for example the capsule "next in the queue", from being transported into the transfer location. Thus, the risk of clogging or crushing of solid objects can be prevented. Further, in certain embodiments of the invention it can be assured that only one solid object at a time is introduced into a specific location in the filter material, into another part of a smoking article or into a flow of material such as for example a flow of filter tow.
  • solid objects denote objects that have a geometrical shape with well-defined boundaries, in contrast to liquids or gases.
  • solid objects include objects which are entirely made of solid state substances, objects having a shell made of a solid substance enclosing a liquid or gaseous core, and objects like gelatine capsules also having well- defined boundaries.
  • the solid object according to the invention may be elastic, deformable and crushable if a sufficiently high force is applied.
  • An embodiment of the apparatus according to the invention further comprises a reservoir for providing a plurality of solid objects, the reservoir comprising an outlet at its lower end.
  • the first wheel is mounted beneath the outlet of the reservoir. Solid objects may be transferred from the reservoir to the first wheel by gravitational force.
  • the ejector pin comprises an outer surface section with a reduced circumference at its side facing the solid objects.
  • the reduced outer dimensions section has a length which is at least as long as a lifting height of the ejector pin between the upper position and the lower position of the movement of the ejector pin.
  • the reduced dimensions section prevents the solid objects remaining on the first wheel from being damaged or crushed by the downward movement of the ejector pin.
  • the cross-section of the ejector pin in the reduced dimensions section is about 20 percent smaller than the average diameter of the solid objects handled by the apparatus according to the invention.
  • the bottom end face of the tip of the ejector pin at least partially comprises a concave shape.
  • a concave shaped tip end face which may especially have a spherical shape or may have any other suitable concave shape, minimizes the impact force on the respective solid object to be transferred to the second wheel due to the matching outer shape of the tip end face.
  • the concave shape of the tip end face allows solid objects having different sizes to be securely transferred to the second wheel.
  • the concave shaped tip end face provides for a reliable and secure transfer of the solid objects to the second wheel without damaging or crushing the solid objects.
  • Such an embodiment is particularly advantageous where the solid objects are crushable flavour release capsules.
  • a further embodiment of the apparatus according to the invention comprises a plurality of ejector pins and a corresponding plurality of frame elements.
  • Each ejector pin is fixedly mounted to a corresponding frame element.
  • the frame elements are arranged to be synchronously rotatable with the first wheel about the vertical axis of rotation of the first wheel.
  • Each of the frame elements is provided with a fixedly attached cam follower.
  • a stationary circumferential cam is provided that is mounted such that the cam follower is guidable by the circumferential cam.
  • the circumferential cam comprises a passive cam portion and an active cam portion.
  • the active cam portion comprises a lowermost point at the transfer location .
  • active cam portion refers to a portion of the circumferential cam that is adapted to create a displacement of the sliding pin when the cam follower is moved through the active portion of the circumferential cam.
  • the active cam portion comprises a descending portion starting at the level of the passive cam portion of the circumferential cam and extending downward to a lowermost point, and a subsequent ascending portion starting at the lowermost point and extending upward back to the level of the passive cam portion of the cam channel such that the sliding pin is displaced from the upper position to the lower position and back upon passing through the active cam section.
  • the term “passive cam portion” is used to indicate the portion of the circumferential cam that does not provide for a displacement of the sliding pin.
  • the cam may move the ejector pin first upwards out of an intermediate position such that a solid object can move under the sliding pin, then move downward to eject the solid object in the transfer zone and finally move back into an intermediate position that blocks the end of the radial channels.
  • the cam follower comprises an elastic element such that the elastic element elastically biases the cam follower towards the circumferential cam.
  • the cam follower allows for the cam follower to follow the cam in the active cam portion in an upward and downward direction. Further, this allows the use of a single sided cam as opposed to a cam channel.
  • a cam channel may be provided that may guide the cam follower in both upward and downward directions.
  • all cam followers of the apparatus are mounted on a detachment means, such that all cam followers are detachable from the cam against the elastic element by the detachment means.
  • This allows for disengagement between the followers and the cam which may provide the possibility to lower all sliding pins into the lower position, irrespective of their position with respect to the transfer zone. This can be advantageous for alignment or maintenance of the apparatus according to the invention.
  • the first wheel has a conical shape defining a surface sloping downwardly from a central portion of the first wheel towards a peripheral portion.
  • the conical shape of the first wheel assists in the distribution of the centrally supplied solid objects due to gravitational forces adding to the centrifugal forces acting on the solid objects upon rotation of the first wheel, so that the capsules and beads are guided to the peripheral portion of the first wheel.
  • the first wheel comprises a plurality of individual radially outwardly extending channels adapted to guiding the solid objects to the peripheral portion.
  • the outlet of the reservoir comprises a cylindrical wall extending down to a predefined distance above the first wheel. This predefined distance is selected such that it allows solid objects to be transported to the peripheral portion only in the individual radially outwardly extending channels. The cylindrical wall thereby prevents the solid objects from being transported to the peripheral portion of the first wheel other than in the channels, so that solid objects may not reach the peripheral portion of the first wheel at a position not intended for the transfer.
  • the first wheel and the second wheel are synchronously driven by a common drive.
  • This is advantageous in that the transfer location at the peripheral portion of the first wheel and a corresponding receiving position on the periphery of the second wheel exactly match at any time.
  • the apparatus may comprise one or more of the following displacement means:
  • First displacement means for generating a maintenance space between the second wheel and a unit for introducing the solid objects into a smoking article.
  • the first displacement means enable a relative movement between a zone where the material, for example filter tow, flows and the apparatus for introducing the solid objects into the said material. This is advantageous with respect to a convenient maintenance, especially cleaning or repair, of the zone where the material flows .
  • Second displacement means for generating a maintenance space between the first wheel and the second wheel. These second displacement means allow for a relative movement between the first horizontally rotating and the second vertically rotating wheel. These second displacement means enable a convenient cleaning of the transfer zone between the first and the second wheel or for the inspection of the ejector pins.
  • Third displacement means for generating a maintenance space between the outlet of the reservoir and the first wheel.
  • an access space may be created which allows for example for a cleaning of the first wheel, especially the cleaning of the radially outwardly extending channels, and also allows for an emptying of the reservoir, for example during maintenance.
  • the introduction of a solid object such as the above-mentioned capsules or beads into the smoking article and in particular into a flow a filter material via the second vertical wheel may be performed in a manner known in the art.
  • it can be performed as disclosed in the international patent application WO-A-2010/055120.
  • the solid objects to be introduced into a flow of filter material are transported in recesses of a vertical transfer wheel to a position where the solid objects are introduced into the flow of filter material.
  • the second wheel is arranged such that it partially extends through a slit into the interior space of a guiding cone through which the filter material flows.
  • a method of transferring a solid object from a first wheel to a second wheel comprises the steps of providing a first wheel being arranged to be rotatable about a vertical axis and being capable of transporting solid objects to a peripheral portion of the first wheel and providing a second wheel mounted beneath the peripheral portion of the first wheel at a transfer location, the second wheel being arranged to be rotatable about a horizontal axis and having recesses for receiving the solid objects provided by the first wheel at the transfer location.
  • the method further comprises providing at least one ejector pin, the at least one ejector pin being slidably arranged between an upper position, in which a solid object may be transported to a location beneath the ejector pin, and a lower position.
  • the solid objects are transferred preferably from a reservoir to the first wheel and further transported to the periphery of the first wheel by centrifugal forces.
  • at least one solid object is transferred from the first wheel to the second wheel by pushing the solid object with the ejector pin into a recess of the second wheel at the transfer location.
  • a reservoir comprising an outlet at its lower end is provided for providing a plurality of solid objects and the first wheel is mounted beneath the outlet of the reservoir. Solid objects provided in the reservoir are then transferred through the outlet of the reservoir to the first wheel.
