Jo Detailed Description
As used herein, the term smoking article' includes smokeable products such as cigarettes, cigars and cigarillos whether based on tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco or tobacco substitutes and also heat-not-burn products and other nicotine delivery product such as aerosol generation devices including c-cigarettes. The smoking article may be provided with a filter for the gaseous flow drawn by the smoker. Whllst not all smoking artides have a filter, embodiments of the present invention relate to smoking articles that are provided with a filter for the gaseous flow drawn by the smoker and which is attached to a tobacco rod in a cigarette filter assembly apparatus using tipping paper.
A known adhesive applicator 1 forming part of a cigarette filter assemNy apparatus (not shown) is illustrated in Figures 1 to 3. The adhesive applicator 1 includes a trough 2 containing a reservoir 3 of adhesive and a transfer roller 4 which is mounted to a frame for rotation about an axis A' above the trough 2 and has a circumferential surface 6 projecting into reservoir of adhesive 3 received in the trough 2. During operation, a layer of adhesive is received on the circumferential surface 6 of the transfer roller 4 and is deposited on the underside surface a of a tensioned web of tipping paper 7 which is moving across the transfer roller 4 as it rotates. The path of the tipping paper web 7 through thc adhcsivc applicator 1 is indicatcd by arrow W' in Figurc land movcs from left to right, as shown on the drawing sheet, from an upstream position on the left hand side to a downstream position on the right hand side.
A web guide roller 8 is positioned to either side of the transfer roller 4. In other words, one web guide roller 8 is ocated in an upstream position and the other web guide roller s 8 is ocated in a downstream position, with the transfer roller 4 located between each of the web guide rollers, and so that each web guide roller 8 lies on opposite sides of a vertical plane extending through the axis A of the transfer roller 4. Each web guide roller 8 is rotatably mounted to a lower end of a respective arm 9 and each arm 9 is pivotally mounted to the frame 5 for rotation about an axis B', so that they can each pivot to move the web guide roflers 8 between an operational and a non-operational position under pneumatic control and in response to a signal from a filter assembly apparatus control unit (not shown).
In an operational position, as shown in Figure 1, the web guide rollers 8 are pivoted about axis B' to alter the path of the tensioned web and force the underside surface a Jo of the tensioned tipping paper web 7 into contact with the surface 6 of the transfer roller 4, so that adhesive is transferred from the rotating transfer rofler 4 to the underside surface a of the moving web 7 in the region of contact between the web 7 and the transfer roller 4. The web guide rollers 8 rotate freely relative to their arms 9 to minimise friction between the circumferential surface 8a of each web guide roller 9 and the tipper surface 7b of the web 7 as the web 7 passes beneath the web guide rollers 9 and over the transfer rofler 4 situated between them. Tt will be appreciated that neither of the web guide rollers 8 come into contact with the transfer roller 4. However, they act on the tensioned tipping paper web 7 so as to alter its path and cause it to come into contact with the transfer roller 4 that is positioned between each of said web guide rollers 8.
When the filter assembly unit is stopped and the web 7 is stationary, the arms 9 pivot in the opposite direction about axis B', as shown in Figure 2. Due to the tension in the web 7, the web 7 moves out of contact with the transfer roller 4. It is necessary for the web 7 to come out of contact with the transfer roller 4 because, if the web 7 remained in contact with the transfer roller 4 when stationary, it would quickly become saturated with the adhesive present on the transfer roller 4 causing the web 7 to break during subsequent processing through the filter assembly unit.
According to one embodiment, one of the arms 9 and its respective web giude roller 8 is omitted from the adhesive applicator iand is replaced with a pressure roller assembly (see Figure 4) that is positioned and configured to app'y pressure to the tensioned web 7 and directly press it into contact with the circumferential surface 6 of the transfer roller 4. The pressure roller 11 forms a nip between itself and the transfer roller 4 to pinch the web 7 as it passes therethrough. As shown in Figure 4, the pressure roller ii is positioned so that the nip against the transfer roller 4 is downstream of a vertical plane extending through the axis A of the transfer roller 4.
More specifically, and with reference to Figures 4 to 8, there is provided a cyindrica pressure roller ii that is mounted for rotation about an axis F' parallel to the axis of rotation A' of the transfer roller 4 and axis B' of the remaining arm 9. The pressure roller 11 is shown in more detail in Figure 8, from which it can be seen that it is mounted to a pressure roller deployment mechanism comprising a yoke 12 in which the pressure roller 11 is free to rotate. The yoke 12 is slideably attached to a mounting plate o 13 which is, in turn, removably attached to a bracket 14 bohed or otherwise attached to the frames. Whilst it is envisaged that the mounting plate 13 may be attached directly to the frame 5 or formed integrally with the bracket 14, it is preferable for the mounting plate 13 and bracket 14 to be readily separable from each other so that the mounting plate 13 can be removed easily from the adhesive applicator 1 together with the pressure roller ii. This not only enab'es the pressure roller assembly 10 to be removed and replaced quickly, but it also facilitates removal and replacement of the transfer roller 4 and the adhesive trough 2, which would otherwise be difficult to detach from the frame 5 in the presence of the pressure roller assembly 10. Furthermore, by making the pressure roller ii and mounting plate 13 removable, it need only have a short stroke between its operational and non-operational positions, i.e. the distance of the pressure roller ii from the surface 6 of the transfer roller 4 may remain short. The mounting plate 13 may be provided with fixing screws or bolts ia that locate in recesses 15 formed in an upper edge 16 of the bracket 14. The mounting plate 13, together with the pressure roller 11, may therefore be hung from the bracket 14 and the fixing screws 14 tightened by means of knurled end caps 17, to hold the pressure roller 11 in place.
The position of the pressure roller 11 can be pneumatically controlled by the filter unit assembly apparatus in the same way that the web guide roller 8 that it replaces is controllcd. A pncumatic lifting cylindcr 18 can bc attachcd to thc mounting plate 13 using a secondary bracket 19 to which the lifting cylinder 18 is attached. Operation of the pneumatic lifting cy'inder 18 will cause the pressure roller ii and yoke 12 to slide rdative to the mounting plate 13 in a radial direction relative to the axis A' of the transfer roller 4 between an operational position, in which it forms a nip with the transfer roller 4, as shown in Figure 4, and a non-operational position, as shown in Figure 5.
In the operationa' position, a web 7 of tipping paper passing through the nip between the pressure roller ii and the transfer roller 4 is pinched and directly urged or biased into contact with the surface 6 of the transfer roller 4 by the pressure roller ii. As web 7 is forced against the transfer roller 4 by the pressure rofler ii, the transfer of adhesive from the transfer roller 4 to the tipping paper web 7 is more even and consistent as the web 7 travels between them. it will be appreciated that, in the absence of the tipping paper web 7, the pressure roller ii would make direct contact with, and press against, the circumferential surface 6 of the transfer roller 4 in its operational position.
Therefore, when the web 7 is present, the pressure roller ii squeezes or pinches the web jo 7 to press it against the transfer roller 4.
In the non-operational position of the pressure roller 11, as shown in Figure 5, the web 7 is no longer pinched or squeezed against the transfer roller 4 by the pressure roller ii and so the web 7 moves out of contact with the transfer roller 4 to prevent the web 7 from becoming soaked with adhesive. When the pressure roller ii moves into its non-operational position, the web moves away from the transfer roller 4 due to tension in the web 7 that causes it to flatten out and assume a more direct, undeflected path through the adhesive applicator 1.
In the above-described embodiment, the remaining web guide roller 8 is retained in order to deflect the web 7 so that it contacts the transfer roller 4 and prior to passing through the nip formed between the pressure roller ii and the transfer roller 4. The web guide roller 8 may be located upstream so that the web 7 is deflected into contact with the transfer roller 4 prior to the web 7 passing through a vertical plane extending through the axis of rotation A of the transfer roller 4, whereas the pressure roller 11 may be located downstream so that the web 7 is nipped to the transfer roller 4 at a point on the transfer roller 4 that is ocated after the web 7 has passed through said vertical p'ane.
However, it is also envisaged that the remaining web guide roller 8 may be omitted so that only the pressure roller 11 is employed to urge the tensioned web 7 against the transfer roller 4. Tn order to increase the extent of contact between the web 7 and the transfer roller 4 other than at the nip, a second pressure roller ii and second pressure roller deployment mechanism may be provided in place of the remaining web guide roller 8, so that the web 7 is nipped to the transfer roller 4 at two spaced locations around the circumference of the transfer roller 4. One pressure roller 11 may be ocated upstream so that the first nip is located prior to the web 7 passing through a vertical p'ane extending through the axis of rotation A of the transfer roller 4, whereas the second pressure roller ii maybe located downstream so that the second nip is located after the web 7 has passed through said vertical plane extending through axis A of the transfer roller 4.
In an alternate embodiment, a pressure roller assembly 10 may be provided in addition to both the arms 9 and web guide rollers 8 shown in the adhesive applicator of Figures 1 to 3. For example, the pressure roller assembly 10 may be located between each of the jo arms 9, as shown in Figure 7. Tn this case, the axis P' of the pressure roller ii could be located directly above the axis A' of the transfer roller 4S0 that the pressure roller ii will move in a vertical path between its operational and non-operational positions.
In another embodiment, the mounting p'ate 13 of the pressure roller assembly 10 may be attached to the end of one of the arms 950 that it will offly be necessary to omit the web guide roller 8 attached to that arm 9. Tn such an embodiment, the arm 9 would first pivot downwardly into its operational position and the pressure roller ii would then slide relative to its mounting plate 13 so that it directly presses the web 7 against the transfer roller 4.
In any of the above described embodiments, a stop member 20 (see Figures 4 and 5) may be associated with each arm 9 and attached to the frame 5 in a fixed position.
When the arm 9 moves into its operational position under pneumatic control, it stops at the same fixed and consistent position due to engagement with the stop member 20.
This ensures that the arm 9, or arms 9, do not move or fluctuate in position due to slight variations in the compressed air pressure. The stop member 20 may be adjustable. For example, the stop member 20 may comprise a screw 21 threadingly received within a fixed block 22 with the arm 9 making contact with the head of the scrcw2lwhcn its opcrational position is rcachcd. Tim position of thc screw 21 maybe adjusted by rotating it within the bthck 22 thereby altering the operational position of the arm 9.
It will be appreciated that movement of the pressure roller ii between operational and non-operational positions will after the web path resulting in a change in web ength.
However, a change in web length can be avoided if the web is passed over a further compensating roller (not shown) whose movement is synchronised with that of the pressure roller ii and which moves to compensate for any changes in web length caused by movement of the pressure roller ii. For example, the compensating roller may retract out of contact with the web as the pressure rofler 11 is brought into contact with the web so that the web length remains unchanged irrespective of the position of the pressure roller ii between its operational and non-operational positions.
The adhesive applicator may be controlled by a controller linked to the filter unit assembly apparatus so that movement of the pressure roller between its operational and non-operational positions occurs automatically in response to other events. For o examp'e, the pressure roller 11 may disengage and move into its non-operational position when the assembly unit stops and re-engage when the assembly unit starts.
