    专利说明:

    [0001] The purpose of the order is a method and unit for feeding beads used in the filters of tobacco industry products, particularly cigarettes.
    [0002] This invention relates to the feeding of spherical or oval objects, which are subsequently placed inside the filter material. For the sake of simplicity, such objects are hereinafter referred to as accounts. Products known in the market are cigarettes, whose filters are provided with beads containing aromatic or flavoring substances. The substances contained in the bills are released during the act of smoking or even before lighting a cigarette by pressing the filter resulting in the bill being crushed.
    [0003] In the production process, a problem that is difficult to solve and, at the same time, very significant, is the feeding of individual beads to the filter forming machine at high speeds, in a way that ensures that the beads remain undamaged and high feed efficiency is maintained, that is, each manufactured filter actually contains an account.
    [0004] In known account feeders, channels are used to feed the beads to the area from which they are transferred to an account supply wheel, with the function of said wheel placing the supplied beads within the filter material.
    [0005] In US patent 7,975,877B2, a bead feeder is described, in which the bead feeding unit is provided with a plurality of radially arranged channels, connected with a bowl, where the channels rotate with the bowl, and the beads are collected, by vacuum transfer by a bead transfer wheel, from bags located at the channel exits and then transferred to a bead supply wheel.
    [0006] WO 2009/071271 describes a bead feeder in which the bead feeding unit is provided with passages rotating with the bowl, where the beads are fed to a bead feeding wheel, after separating the lower bead those located above it, using a stationary arcuate wedge end element.
    [0007] WO 2009/071272 describes a similar bead feeder, in which the beads are fed to a bead supply wheel using two plates having a plurality of openings and rotating in relation to each other, and one bead is fed after aligning the respective openings directly on top of each other.
    [0008] US patent 7,833,146B2 shows a device for feeding beads through curved channels from a bowl directly to a bead supply wheel, where the channels rotate with the bead bowl, and the beads are harvested from the bowl by transfer to vacuum.
    [0009] In the devices shown above, the bills are transferred from the supply channel retention pockets to the transfer wheels or to a wheel supplying the bills for the filter material. However, in the case of very high efficiencies, the construction of the elements may be so complicated or may require so much space that, in order to ensure correct transfer of the beads, a change in the diameter in which the beads are transported may be necessary. A change in diameter can also be forced by building elements by collecting the beads in order to transfer them to a wheel supplying the beads to the filter material.
    [0010] The objective of the invention is to develop a bead chain feeding unit, in which the bead flow, in the form of a plurality of individual bead chains, spaced along a first arc with a first radius, is transformed in a stream of beads in the form of an arched stream of individual beads along a second arc with a second radius.
    [0011] The subject of the invention is a method of feeding beads, in a unit to transfer a chain of beads from a tobacco industry system, of receiving bags for external feeding of bags, in which the beads are transferred along grooves guides arranged in guide plates, comprising the steps in which: the beads are fed to a guide chamber formed at the intersection of a guide groove of a first guide plate and a guide groove of a second guide plate; at least one guide plate is rotated in relation to the second guide plate, which forces the movement of the guide chamber, so that the distance from the guide chamber to the geometric axis of rotation of the guide plates changes; the beads are transported from the guide chamber to an external feed pouch.
    [0012] The subject of the invention is also a unit to feed a chain of beads in a tobacco industry system machine, to receive bags for external feeding of bags, through guide grooves arranged in guide plates. A unit according to the invention comprises two guide plates located on top of each other, while the guide groove of the first guide plate and the guide groove of the second guide plate intersect to form at least one bead guide chamber, where at least one of the guide plates is mobile.
    [0013] A unit according to the present invention is characterized by the fact that the first guide plate is stationary.
    [0014] A unit according to the present invention is characterized in that a guide channel of the first guide plate forms a plurality of guide chambers with a plurality of guide channels of the second guide plate.
    [0015] An account transfer unit according to the present invention allows feeding a chain of accounts in such a way that at each stage of account transfer the position of the accounts is fully controlled, that is, it is not possible for an account take a random position, which would result, for example, in an undesirable crushing of an account. The unit can be used in any bead feeder where it is necessary to change the radius of the arc in which a bead chain moves. The unit transfers a chain of individual beads at a speed adjusted to highly efficient filter-making machines.
    [0016] The purpose of the invention has been shown in a preferred embodiment in a design in which:
    [0017] Fig. 1 shows an account feeder in perspective view.
    [0018] Figs. 2a through 2d show a fragment of an account feeder of the first embodiment in a top view in successive account transfer stages,
    [0019] Fig. 3 shows a sectional view of a retention pouch of the first embodiment of the guide channel, marked in Fig. 2a as A-A, before pushing a bead out of the retention pouch,
    [0020] Fig. 4 shows a sectional view of the retention pouch of the first embodiment of the guide channel, marked in Fig. 2a as B-B, after transferring an account to the supply wheel,
    [0021] Fig. 5 shows a sectional view of a retention pouch of the second embodiment of the guide channel, marked in Fig. 2a as A-A, before transferring an account,
    [0022] Fig. 6 shows a sectional view of the retention pouch of the second embodiment of the guide channel, marked in Fig. 2a as B-B, after transferring an account to the supply wheel,
    [0023] Figs. 7a to 7c show a fragment of an account feeder of the second embodiment in a top view in successive account transfer stages.
    [0024] Fig. 1 shows a feeder 1 for beads 2, provided with a storage container 2A for beads 2, a chain feed unit 3, a unit 13 for transferring the beads to a supply wheel and the supply wheel 7 for supplying beads 2 for the filter material transported along a funnel 9. For reasons of simplification, the elements holding the individual units have not been shown.
    [0025] Fig. 2a shows a fragment of a bead feeder 1 in a top view. A bead supply unit 3 is provided with a plurality of stationary channels in the form of tubes 4, spaced in an arc of radius R1, with said tubes being supplied by container 2A, while a bead 2 above the entrance to a of the tubes was shown. At the outlets of the tubes 4, first holding pockets 14 (Fig. 3) are located, of which the beads are transferred to second receiving pockets 18 (Fig. 4) belonging to a unit 13 to transfer the beads 2 to the supply wheel 7 , while the pockets are located in the area between a first guide plate 5 and a second guide plate 6. After passing through a substantially horizontal guide channel 19, between the first guide plate 5 and the second guide plate 6, the beads are then supplied downward to an external power pouch 21, moving in an arc of radius R2. The beads are also transferred to the bags on the circumference of the supply wheel 7, which places the beads within the filter material transported inside the funnel 9. The guide channel 19 is formed of two parts, the guide channel 19 should be considered as a path that a bead 2 'covers between the receiving bag 18 and the entrance of the feeding bag outwards 21. The upper part of the guide channel 19 is defined by a guide groove 5A, shaped on the base side of the first guide plate 5 , oriented towards the second guide plate 6, the lower part of the guide channel 19 is defined by a guide groove 6A on the top side of the second guide plate 6 oriented towards the first guide plate 5, while the grooves 5A and 6A are intersect, which is described with reference to Fig. 2a.
    [0026] Fig. 2a shows a fragment of a bead feeder 1, according to the invention, in the first embodiment. In a top view, a fragment of the bill 2, feeding the unit 3 and the unit 13 to transfer the bills 2 to the supply wheel 7, has been shown. Unit 3 is provided with a plurality of tubes 4 (in an arc of radius R1), while all tubes 4 are filled with beads 2. For the sake of simplicity, the elements attaching the tubes to the structure of the feeder 1 and the transmission elements were not shown. The bead feeding unit 3 is provided with rotary feeding means, in the form of a cam 8, comprising pushing segments 10, having pushing edges 11, while the cam 8 rotates about the geometric axis of rotation 12 at speed ®1. The first plate 5 is stationary, while the second plate 16 is rotatable and rotates about the axis of rotation 12 at speed w2, lower than the speed w1 of cam 8. The guide grooves 5A and 6A of both plates Guide 5 and 6 are shown in dashed lines. At the intersection of the grooves 5A and 6A a guide chamber 22 is formed which, in view of the direction of rotation of the plate 6 and the orientation of the grooves, moves so that the distance from the guide channel 22 to the geometric axis of rotation 12 increases between radius R1 and R2. A solution is also possible where both plates 5 and 6 are rotatable.
    [0027] Fig. 3 shows a sectional view of any tube 4, where, for example, in Fig. 2a, the section was marked as A-A. The lowermost bead 2 ', of the column of beads 2, is located in the holding pocket 14, arranged at the outlet of the tube 4, limited from below by a plate 15 and on the sides by the plate 5 and a circumferential edge 16 of the cam 8.
    [0028] Fig. 4 shows a sectional view marked as BB in Fig. 2a, which corresponds to a situation in which the working segment 10, moving in a circular path, during the rotation of the cam 8, passed through a successive pouch 14 under a successive tube 4 and caused or pushing the bead 2 'out of the holding pouch 14, and said bead moved to the receiving pouch 18 and was further transferred substantially and horizontally into the guide channel 19 being the movement path of the guide chamber 22, and then down to the feed pouch 21 and to the supply wheel 7 in which it is held in a known manner, for example, by vacuum.
    [0029] Figs. 5 and 6 show a similar transfer from an individual bead 2 ', where the guide channel 19' makes feeding the bead 2 'directly to the supply wheel 7' possible, while the pouch 21 'is located at the level of the guide channel 19 '.
    [0030] Figs. 2a, 2b, 2c and 2d show successive stages of movement of the bead 2 'within the guide chamber along the guide channel 19 (bead movement path) in the first embodiment. In Fig. 2a, the push segment 10 is in a position exactly in front of the bead 2 'located at the distance R' to the axis of rotation 12, while the guide chamber 22, at the intersection of the grooves 5A and 6A, begins to form. In Fig. 2b, the push segment 10 passed through the bead 2 'and caused it to slide into the chamber 22, which, with the rotation of the plate 6 and the groove 6A, begins to move away from the geometric axis of rotation 12, while at the moment of transferring the account the holding bag 14 and the receiving bag 18 were positioned substantially radially. In Fig. 2c, the bead 2 'still remains in the guide chamber 22, just before feeding it into the feed pouch 21. In Fig. 2d the bead 2' was placed in the feed pouch 21 and moving it will be done more with the feed pouch 21 moving in an arc of radius R2 and rotating with the guide plate 6 at speed w2, while the radius of arc R2 is greater than the radius R1. Finally, the account will be fed to supply wheel 7.
    [0031] Fig. 7a shows a fragment of a bead feeder in a second embodiment. The tubes 4 with the beads located in them are spaced in an arc of radius R1. In the first guide plate 5 ', a guide groove 5B is formed, while in the second guide plate 6' a guide groove 6B and a guide groove 6C are formed, while groove 5B intersects with grooves 6B and 6C, forming the chambers. 22 'and 22 ”, respectively, into which accounts 2' and 2” are inserted. Figs. 7a, 7b and 7c show the stages of movement of the bead 2 'and bead 2 "of the guide chamber 22' and of the guide chamber 22", respectively. The guide groove 5B, shaped on the first guide plate 5 'in Fig. 7A, begins to intersect with the guide groove 6B, shaped on the guide plate 6', and at said intersection the guide chamber 22 'begins to form. When the guide chamber 22 ', being a receiving pocket, is positioned substantially and radially to the holding pocket 14, the bead 2' is pushed into this guide chamber by the pushing segment 10 '. The same groove 5B also intersects with the guide groove 6C and at said intersection the guide chamber 22 'is formed, into which previously the bead 2 "has been pushed. As shown in Fig. 7b, during the rotation of the plate 6 ', the beads 2' and 2 ”move, so that their distance to the axis of rotation 12 'increases between the radius R1 and R2. In Fig. 7c the bead 2 "is placed inside the feed pouch 21 'and will move more in a circle of radius R2, along with the rotating plate 6 and will be fed to the supply wheel 7.
    [0032] In another embodiment of the device according to the present invention, the guide grooves 5A and 5B can be formed as channels with supplied vacuum. Such a solution ensures that a bead does not rub against the lateral edges of the groove and is somewhat rolled along the groove.
