Definitions

  • the present invention relates to a combiner for use in the manufacture of rod-shaped articles comprising at least two components.
  • Rod-shaped articles for example smoking articles, may comprise a plurality of cylindrical components attached in axial alignment.
  • these components typically include a wrapped rod of tobacco and a filter.
  • the filter may itself comprise a plurality of cylindrical components.
  • Heated smoking articles in which tobacco or other material is heated rather than burnt may comprise additional cylindrical components, for example a heat source for igniting a heated smoking article.
  • one or more of the components may be initially presented as a double or quadruple length component, that is, a component which is two or four times the length of that component in the final smoking article. These multiple lengths are typically cut and separated and other components introduced between the cut portions. This complex combining procedure is carried out on machinery known as a combiner.
  • a conventional combiner comprises a plurality of drums.
  • the circumferential surfaces of the drums have axially aligned channels, for example grooves or notches, for the reception of the cylindrical components of the smoking article to be manufactured.
  • a method of making an axially aligned assembly of components of rod shaped articles comprising supplying a component from one of a plurality of component supply stations to a channel of an assembler, repeating the step of supplying a component to the channel of the assembler until a desired assembly of components is in the channel of the assembler, transferring the assembly from the assembler and controlling the relative positions of the supply stations and the assembler and controlling the provision of the components to the assembler from the supply stations.
  • the assembler moves from one supply station to another.
  • the relative movement of the assembler and the supply stations is controlled.
  • the method also includes controlling the transfer of the assembly from the assembler.
  • the method of the invention is particularly useful in the manufacture of smoking articles.
  • the assembler includes a plurality of channels.
  • Transfer of the complete assemblies can be, for example, transfer of the assemblies to successive channels in the circumferential surface of a transfer drum. In other embodiments, transfer can be by a 'pick and place' device. After transfer, the complete assemblies may travel transverse to their axis or longitudinal to their axis. The complete assemblies will typically move to a downstream part of the combiner, such as a rod making unit where they can be wrapped together and if necessary cut or combined with further components. In the case of assemblies which are a multiple of the required final component, the assemblies will generally be transported longitudinally to their axis after wrapping and cut by a cutter positioned to one side of the path of the wrapped assemblies.
  • the channels on the assembler are of V cross section so that they can accommodate cylindrical components of different diameter.
  • the supply of components to a channel of the assembler preferably takes place immediately after an assembly has been transferred from the channel so that the channel contains components for only a single design of smoking article at one time.
  • a component supply station includes a pusher for pushing a rod of the component material partly into a channel of the assembler and a cutter for cutting the rod to leave a component in the channel.
  • the length of rod pushed into the channel is the length of that component required in the complete rod-shaped article. It may be a multiple of the length of the component required in the final product, in which case the component will be cut downstream (this is discussed further with reference to Figures 6A, 6B and 6C).
  • the length of rod pushed into the assembler channel before the rod is cut can be increased or reduced.
  • a supply station provides a plurality of rods of the component material and the pusher pushes each rod the required distance into a respective channel of the assembler before the rods are cut to leave the components in the channels of the assembler.
  • the assembler comprises one or more trays, preferably 1 to 10 trays, having channels on a principal surface. The trays are moved between the component supply stations and receive components at the supply stations.
  • the assembler is a continuous belt running around rollers.
  • the belt has channels transverse to its direction of movement.

  • the channels may be defined by pairs of parallel circular section rods extending across the belt.
  • the belt may be a strip of flexible material or it may be one or more chains.
  • the channels in the assembler are transverse to the transport direction of the assembler.
  • the assembler is a rotatable turntable having radial channels.
  • the component supply stations are disposed around the circumference of the turntable.
  • the turntable rotates past the supply stations and receives components as it does so.
  • a component assembly station includes a component receiver, each component receiver associated with a respective one of the component supply stations.
  • a plurality of components is delivered to the component receiver.
  • the components are taken from the component receiver, for example by a 'pick and place' device such as a selective compliant assembly robot arm (SCARA) or an industrial robot having a Cartesian anthropomorphic or Delta architecture, and placed in the channels in the assembler to form the assemblies of axially aligned components.
  • SCARA selective compliant assembly robot arm
  • the component receivers may be separate from each other or one or more component receivers at adjacent component supply stations may be integral with each other.
  • the component receiver is preferably a tray having a plurality of channels for reception of the components.
  • the assembler can move from one component supply station to the next in a fixed order or the order can be varied according to the design of smoking article to be made.
  • the assembler can receive one or more components at each component supply station or at only selected supply stations, according to the design of smoking article.
  • the assembler can move continuously between the component supply stations or it can index between them, stopping adjacent the stations. Depending on the design of the smoking article to be manufactured, the assembler can receive components from every supply station or from only selected stations. The assembler can stop more than once at one or more of the supply station if the complete assembly of components includes more than one of a particular component. The assembler preferably moves on a continuous path so that after the transfer station, it returns to the first supply station. The path may be of any configuration.
  • One preferred path for the assembler comprises two straight line portions joined by curved portions, one straight line portion of the path taking the assembler past the component supply stations to the transfer station and the other straight line portion returning it to near the first supply station.
  • Another preferred path for the assembler is circular.
  • the assembler can move in the same transport direction throughout, or it can move forwards and backwards, to collect components in the correct order.
  • the assembler can move transverse to the transport direction to enable components to be correctly positioned in the channels.
  • the supply stations, or those portions of the supply stations immediately adjacent the assembler can move transversely to the transport direction of the assembler to enable components to be correctly positioned in the channels.
  • the channels of the assembler can be lined with paper or other wrapping material before components are introduced into the channels.
  • the supply of components to supply stations can be controlled by the controller.
  • the controller can change what components are supplied to a supply station. Components can be switched from one supply station to another by changing how supply hoppers of the components distribute components among the supply stations.

  • the number of supply stations is preferably between 2 and 10,
  • the assembler is arranged to move from one supply station to another.
  • the controller controls the relative movement of the assembler and the supply stations.
  • the controller controls the mentioned transfer of the said assemblies of axially aligned components from the assembler.
  • Axial alignment of the components is achieved essentially in the longitudinal direction of an underlying rod-shaped article.
  • the different cylindrical components are introduced into the combiner at different locations. They are transferred from drum to drum, if necessary being cut and separated during this process as described above, until an appropriate assembly of axially aligned components has been formed.
  • the assembled components are typically joined together with an overwrap and, if necessary, cut to an appropriate length for the next stage of manufacture. If the complete assemblies are only semi-finished articles but not finished articles, the complete assemblies are combined with other cylindrical components or semi-finished articles, joined by overwrapping and, if necessary, cut to length. The procedure is repeated until a finished article is made.
  • a combiner to be used for the manufacture of rod-shaped articles can easily and rapidly switch from making rod-shaped articles of one design, for example using components of first length, diameter or relative position in the article, to articles of a second design, in which at least one of the length, the diameter or the relative position of the components is different.
  • the invention particularly allows for the manufacture of smoking articles with tobacco rods of various lengths of the above mentioned heated smoking article type, in which tobacco or other material is heated rather than burnt. Different rod lengths may be required because of the heated smoking articles have tobacco rods of different lengths different lengths or because the heaters used for the heating of the tobacco rod are of different lengths.
  • the filter lengths or lengths of other components of these smoking articles for example mouth pieces, may differ as well, for example depending on the technology used for the heating of the tobacco and the filtering of the generated aerosol or smoke.
  • the combiner according to the invention can be used for combining smoking article filter components into final filters, to join filters to rods of smoking material, such as tobacco, and to combine components of heated smoking articles, for example tobacco rods, into final heated smoking articles which may comprise at least one tobacco rod and at least one filter component.
