Description

  The present invention has at least one turning means for turning the filter tow belt, and the turning means arranges the conveying path at an angle with respect to the first path part and the first path part. At least one along a transport path attached to the filter manufacturing machine for manufacturing filter rods for smoking articles, in particular cigarettes, from the filter tow strip, which is divided into a second path portion towards the filter manufacturing machine The invention relates to a device for conveying two filter tow bands.

  In order to produce filter rods for smoking articles, in particular cigarette filter rods, on filter production machines provided for this purpose, so-called filter tows are used which are drawn out in the form of strips from a filter tow source. A filter maker typically has an apparatus for processing filter tows and a subsequent filter strand maker. In a filter tow processing device, the filter tow band is usually processed by stretching and application of a softening agent, formed into a circle, and then delivered to the filter strand making machine in the desired shape and density for further processing. The filter strand manufacturing machine manufactures a filter strand by wrapping with a covering material tape from the processed filter tow band, and this filter strand is finally cut into filter rods having a desired length.

  The filter tow source is typically used to contain at least one filter tow bale from which the filter tow is drawn continuously as a strand, band or belt (hereinafter also referred to as “filter tow band”). . In order to supply the filter tow band to the processing device of the filter manufacturing machine, a so-called gantry is used in the case of the current commercially available apparatus, and the tow band is drawn into the filter maker from the filter tow bale via this gantry. However, this apparatus is only in a situation where the filter tow band can be supplied to the filter manufacturing machine only from a fixed direction.

European Patent Application Publication No. 1 800 553

  The object of the present invention is to realize an essentially direction-independent installation of a filter making machine with respect to a filter tow source or a conveying device connected after the filter tow source, thereby connecting after the filter tow source or the filter tow source. An object of the present invention is to provide a configuration for realizing an essentially direction-independent supply of a filter tow belt drawn from a conveying device to a filter manufacturing machine.

  In order to solve this problem, the turning means is supported so as to be movable about a rotation axis that is substantially parallel to the second path portion or substantially coincides with the second path portion. And a turning means for turning the filter tow belt, and the turning means has a first path portion and an angle with respect to the first path portion. For transporting the filter tow strip along the transport path to a filter manufacturing machine for manufacturing filter rods for smoking articles, in particular cigarettes, from the filter tow strip, which is divided into a second path portion towards the manufacturing machine Propose the device.

  The present invention allows an essentially direction-independent supply of filter tow bands to the filter making machine, whereby the filter making machine's intrinsic orientation relative to the filter tow source or a transport device connected after the filter tow source. Can be installed independent of Therefore, according to the present invention, it is possible to obtain an advantage that the tow supply unit can be formed without depending on the location of the filter manufacturing machine when the production direction is adjusted. In this case, even when the filter tow belt is disposed, the filter tow belt in the second path portion between the turning means and the filter manufacturing machine may be controlled by the twist or the twist. Can try to reduce the loss of quality.

  Certainly, in order to perform semi-automatic bale exchange, it is possible to rotate the guide ring that guides the filter tow belt between two positions respectively limited to the center on each filter toe veil. As is well known, this prior art is supported so as to be movable about a rotation axis which is located substantially parallel to or substantially coincides with the path portion between the turning means and the inlet of the filter manufacturing machine. It does not give any indication about providing a turning means.

  Preferred embodiments and developments of the invention are described in the dependent claims.

  Preferably, the turning means is in a rotational position in which the filter tow belt reaches the turning means essentially straight and without bending and twisting from the filter tow source or a conveying device connected after the filter tow source along the first path portion. Is movable.

  The turning means comprises a guide surface that is at least partially curved from the first path portion toward the second path portion, with the guide toe so that the filter tow band is spread over the surface in the form of the first The development of this configuration, which is transportable from the path part to the second path part, is directed to a guide surface that is essentially bent and / or essentially untwisted of the filter tow band coming from the first path part. The turning position (6) stands out by being movable at a rotational position allowing surface contact.

  For this reason, the guide surface is formed to allow sliding contact with the guide surface of the filter tow belt. In the case of such an extension, for example, the turning means comprises a curved upper surface constituting a curved guide surface or a curved flat portion whose outer surface constitutes a curved guide surface, the flat portion being It is plate-shaped or consists of plate material. Furthermore, at least the cross-section of the outer surface of the turning means is at least partly provided with an inverted U-shape. In this case, the concept of the inverted U-shape does not mean that the “U-character” must be forced to be reversed, but the “U-character” tilts diagonally downward. It may also be suitable for.

  However, the turning means can also have the shape of a disc with a guide surface formed around it. Instead of a configuration in which the filter tow band slides on the turning means, the disk is rotatably supported as a roller, and the filter tow band may pass through this roller.

  In another preferred arrangement, a support member is provided, the upper part supporting the turning means and the lower part being movable along a track surrounding the second path part. In particular, the trajectory is circular, and the center point of the circular trajectory is located approximately on the rotation axis. This configuration, in which the support member is provided as a kind of rotating tower and supports the turning means at the upper end, allows the installation independent of the direction of the filter manufacturing machine to the filter tow source or the conveying device connected after the filter tow source. To provide an arrangement which is particularly simple in structure and at the same time effective.

  In the developed form of the above configuration, a pedestal that is rotatably supported around a rotation axis and that can be attached to a filter manufacturing machine is provided, and the pedestal includes a through hole through which the second path portion passes. The lower portion of the support member is fixed to the pedestal at a distance in the radial direction with respect to the rotation axis. Preferably, the axis of rotation passes through the through hole and the pedestal can have the shape of a table extending substantially perpendicular to the axis of rotation.

  In particular, at least one guide element is provided for guiding the filter tow band of the second path part between the turning means and the filter maker. For purpose, this guide element should be arranged on the support member. A preferred development of this configuration is distinguished by the fact that the guide element is provided with a through hole, through which the second path portion passes, whereby the filter tow band can be passed. In particular, the guide element can be formed in particular as a ring oriented substantially perpendicular to the second path part.

  Particularly advantageously, the device according to the invention is suitable for supplying a filter tow band substantially perpendicular to the filter maker, so that the second path section from the turning means to the filter maker is approximately The direction is adjusted vertically.

  In this case, in addition to the at least one guide element according to the above configuration, which normally holds the filter tow band only in the second path portion in the second path section from the turning means to the filter manufacturing machine, Rather than providing other types of guide means for guiding the filter tow band through a curved or curved track, or conveying means for dynamically moving the filter tow band, It should be noted that the two path portions may be essentially free hanging or “movable” and the second path portion may extend essentially straight.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 schematically shows a partial cross-sectional view of a transport device according to a preferred configuration of the invention and an inlet region of a subsequent filter manufacturing machine. 1 shows an enlarged view of the first part of FIG. 1 illustrating the area of the turning plate. The 2nd part of FIG. 1 which illustrated the lower part and base of the supporting member is expanded and shown. The structure which consists of two conveyance apparatuses and one succeeding 2 strand filter manufacturing machine is shown by a perspective view schematically. The structure of FIG. 4 is shown with a top view. The structure of FIG. 4 is shown with a rear view.

  In each attached figure, there are schematically shown a plurality of components for transporting and processing filter tow and a device comprising these components for producing filter rods for smoking articles, in particular cigarettes, in a strand process. And in part where the drawings show in nature the components, parts and details necessary for an understanding of the invention. The usual parts in the mechanical configuration of the machine, such as machine frames, holding parts, bearings and panels, for example, are not shown in the figures for better understanding unless they are important. It should be understood that the configuration shown in each figure is part of a device (not shown in its entirety) for producing filter rods for smoking articles, in particular for filter cigarettes.

  The filter tow can be continuously in the form of a band, belt or strand, for example consisting of at least one container or receptacle for the filter tow bale, or optionally from a filter tow source which can for example consist of a direct filter tow bale It is pulled out and transported via a transport device to a processing unit that is part of a filter manufacturing machine, usually arranged at a distance. Although the filter tow source and the filter tow veil are not shown in FIGS. 1 to 3, a portion of the transfer device on the outlet side of the transfer path 2 is schematically shown. In the illustrated embodiment, The filter tow belt 4 is guided through this conveyance path. After exiting the transport path 2, the filter tow band 4 crosses the first path portion to the turning means formed as the turning plate 6 in the illustrated embodiment.

  As can be seen in particular in FIG. 2, in the illustrated embodiment, the cross section of the turning plate 6 has an inverted “U-shaped” shape arranged vertically. In the illustrated embodiment, the turning plate 6 is fixed to the upper end portion 8a of the support member 8 arranged vertically, and enters the conveyance path 2 through the first path portion and is perpendicular to the drawing plane of the figure. The filter tow band 4 spread over the surface is adjusted so as to make surface contact with the outer surface 6a of the turning plate 6 as seen in FIGS. As described above, since the cross section of the turning plate 6 has an inverted U-shaped shape, the outer surface 6a is correspondingly curved, and the filter tow band 4 is turned along the outer surface. Accordingly, the outer surface 6a serves as a guide surface.

  In the illustrated embodiment, the turning means formed as the turning plate 6 is provided as a kind of sliding bearing on which the filter and the spare 4 are dragged on the curved outer surface 6a. However, as an alternative, it is also conceivable to provide a roller or roll around which the filter tow belt is guided, which is rotatably supported as turning means in order to reduce the friction.

  In the illustrated embodiment, the filter tow band 4 is turned downward substantially vertically via the turning plate 6. In the illustrated embodiment, the first path portion extends substantially horizontally so that a turning of about 90 ° is performed.

  A guide ring 10 for guiding the filter tow band 4 is attached to the support member 8. Since the guide ring 10 is disposed beside the support member 8 and is adjusted in a substantially horizontal direction, the filter toe band 4 passes through the guide ring 10 almost vertically. As further appreciated in FIGS. 1 and 2, in the illustrated embodiment, the guide ring 10 is located adjacent to the upper end 8 a of the support member 8 below the turning plate 6.

  As can be seen particularly in FIG. 3, the support member 8 has a lower portion 8 b fixed to the outside of the center of the turntable 12. As already described, the support member 8 is formed as a vertical bar, but the turntable 12 has the shape of a disk located in a horizontal plane. By means of the thrust bearing 14, the turntable 12 is supported on the mounting plate 16 so as to be rotatable about a rotation shaft 18. In the illustrated embodiment, the rotary shaft 18 coincides with a second path portion through which the filter tow band 4 passes from the turning plate 6 toward the filter manufacturing machine 22. Accordingly, the rotating shaft 18 also passes through the peripheral edge 6b on the outlet side of the turning plate 6 facing downward in the direction of the filter manufacturing machine 22 (FIG. 2), and preferably the rotating shaft is approximately at the center of the turning plate. Pass through.

  As can be seen in FIGS. 1 and 3, the mounting plate 16 is secured to the upper surface 20 a of the housing 20 of the filter making machine 22. As can be further seen in FIG. 3, the turntable 12 includes a central through hole 12a, and the base plate 16 similarly includes a through hole 16a. Both through-holes 12a, 16a have a circular shape whose central point is located on the rotary shaft 18 already described above, and therefore are oriented coaxially with each other, and the filter tow band 4 is shown next. Together, the passage for the filter tow band 4 is configured so that it can enter the filter maker 22 for further processing through the unused inlet.

  The filter manufacturing machine 22 is usually provided with a processing device, in which the filter tow band 4 is stretched, a softening agent is applied, and is formed into a circular shape, whereby a desired shape and density for subsequent processing are obtained. The filter strand manufacturing machine forms a filter strand from the processed filter tow strip by wrapping with a covering tape, and the filter strand is finally sent to a filter strand manufacturing machine connected after the processing apparatus. And then cut into filter rods having a desired length. 1 and 3, only the inlet region of the processing device of the filter maker 22 is shown schematically in cross-section, including two rolls 24, 25 that together make up a draw roll pair. In the illustrated embodiment, processing devices are used in the filter maker 22 that pass through various processing units that are positioned up and down along a processing section in which the filter tow band 4 is vertically directed downward. In this case, the downward movement of the filter tow band 4 is supported by the influence of gravity. In order to facilitate retraction, the retraction roll pairs 24 and 25 are additionally provided directly below an inlet (not shown). After the pulling roll pair 24 or 25, the filter tow strip 4 passes through various processing units, so that the filter tow strip 4 normally undergoes pre-stretching, main stretching, spraying and circular shaping. receive.

  By supporting the turntable 12 so as to be rotatable about the vertical rotation shaft 18, the lower portion 8 b draws a circular orbit about the rotation shaft 18 when the turntable 12 rotates. This also applies to the entire support member 8, which in turn allows the turning plate 6 to move accordingly about the rotation axis 18. As can further be seen in FIG. 1, the filter tow strip 4 extends from the turning plate 6 to the filter making machine 22 along the second path portion, substantially parallel to the support member 8 and to the support member 8. Pass at intervals.

  While configuring the entire apparatus, the turntable 12 is connected to the filter manufacturing machine 22 by a filter tow band 4 coming from the conveying path 2 along the first path portion as shown in FIGS. Is moved to a rotational position to allow surface contact to the outer surface 6a of the curved turning plate 6 without substantial bending and / or essentially twisting, and then usually with locking means not shown Fixed by. In this case, the filter tow band 4 along the second path portion between the turning plate 6 and the filter manufacturing machine 22 is as shown in each figure (there is a virtual plane perpendicular to the drawing plane). Instead of passing through a virtual plane, it may be twisted or twisted. In order to control such torsion, the guide ring 10 is provided on the inner surface (not shown), which has already been described above, so that the filter tow band 4 can contact along the second path portion. . A similar guide function can be performed by the through-holes 12a and 16a positioned on the upper and lower sides of the turntable 12 and the mounting plate 16 on the same axis. It is also conceivable to have a diameter large enough to eliminate Since the drawing roll pairs 24 and 25 in the filter manufacturing machine 22 are adjusted in the fixed direction, in the second path portion of the illustrated embodiment, specifically, the peripheral edge 6b on the outlet side of the turning plate 6 and The filter tow band 4 is twisted between the pulling roll pairs 24 and 25. Preferably, the central axis of the filter tow band 4 on the path along the second path portion coincides with the rotation axis 18. However, basically, a situation in which the rotation axis is located outside the center of the filter tow band 4 extending along the second path portion is also conceivable. In any case, the filter tow band 4 is twisted in the second path portion around the rotation axis.

  FIGS. 4 to 6 show two conveying devices or one two-channel conveying device and one filter manufacturing machine 22, so that the filter manufacturing machine includes two filter tow bands 4-1 and 4-2. Is supplied. The filter manufacturing machine 22 illustrated in FIGS. 4 to 6 is a two-strand filter manufacturing machine.

  Both filter tow strips 4-1 and 4-2 are each drawn from an attached filter tow source, which in the illustrated embodiment of FIGS. 4-6, is provided with an attached container 32-1 or 32-2. The filter tow veil 30-1 or 30-2 is contained in Further, in the illustrated embodiment, one upright support member 34-1 or 34-2 is fixed to each of the containers 32-1 and 32-2, and the attached filter toe bail 30- is attached to the upper end thereof. A turning unit 36-1 or 36-2 for turning a part of the filter tow band coming from 1 or 30-2 to the attached transport path 2-1 or 2-2 is disposed.

  After exiting the transport path 2-1 or 2-2, the filter tow band 4-1 or 4-2 reaches the turning plate 6-1 or 6-2. In the illustrated embodiment, the turning plates 6-1 and 6-2 have a bent shape of at least 90 ° with essentially horizontal legs and essentially vertical legs, but the turning plates are selectively Like the turning plate 6 of FIGS. 1 and 2, it may have an inverted “U-shaped” configuration arranged essentially vertically.

  In order to hold both turning plates 6-1 and 6-2, an essentially vertical common support member 80 is provided, which essentially supports the first turning plate 6-1 at its upper end. An essentially horizontally oriented second gantry 82-2 is disposed to support the horizontally oriented first gantry 82-1 and second turning plate 6-2. Similar to the turning plate 6 of the configuration shown in FIGS. 1 and 2, in the configuration of FIGS. 4-6, it enters from the attached half-feed path 4-1 or 4-2 in the illustrated embodiment in a substantially horizontal direction. As shown in FIG. 4, the tow strip 4-1 or 4-2 spread on the surface is in contact with the outer surface of the attached turning plate 6-1 or 6-2. 6-2 is adjusted in direction. As described above, the turning plate 6-1 or 6-2 has a shape that is bent at least approximately 90 ° when viewed in cross section, so that its outer surface is correspondingly curved, and along this outer surface, respectively. The filter tow band 4-1 or 4-2 is turned. Therefore, also in this embodiment, the outer surfaces of the turning plates 6-1 and 6-2 serve as guide surfaces.

  Similar to the configuration shown in FIGS. 1 to 3, the turning plates 6-1 and 6-2 have a function of a sliding bearing in which each filter toe band 4-1 or 4-2 is dragged on the curved outer surface. . However, as an alternative, it is also conceivable to provide a roller or roll around which the filter tow belt is guided, which is rotatably supported as turning means in order to reduce the friction.

  In the illustrated embodiment, the filter tow bands 4-1 and 4-2 are turned downward substantially vertically via turning plates 6-1 and 6-2. In the illustrated embodiment of FIGS. 4-6, the path portion defined by the attached transport path 2-1 or 2-2, comparable to the first path portion of the configuration illustrated in FIGS. Because it extends horizontally, a turn of about 90 ° is made to a second path portion comparable to the second path portion of the configuration shown in FIGS.

  The support member 80 has a substantially horizontal direction adjusted at a distance from the bases below the tops, and hence below the bases 82-1 and 82-2 supporting the turning plates 6-1 and 6-2. Is provided, which supports a guide element 86 where the filter tow strips 4-1 and 4-2 are both oriented in the direction of the filter making machine 22. To the subsequent (third) path portion of. The guide element 86 comprises a guide surface, which is curved in response to turning, so that in the illustrated embodiment, the curved toe surface is similarly fitted with filter tow strips 4-1 and 4-2. It serves as a kind of sliding bearing that can be dragged. Optionally, however, a roller or roll that is rotatably supported against both filter tow strips 4-1, 4-2 or one of filter tow strips 4-1 or 4-2 to reduce friction. It is also conceivable to provide

  A deployment nozzle 88 is arranged at the downstream end of the guide element 86, which deployment nozzle is in the filter maker 22 and thus from a compressed air source not shown, via a hose 89. Supplied with compressed air.

  The support member 80 is fixed to a base or a foundation not shown in FIGS.

  Similar to the configuration shown in FIGS. 1 to 3, in the configuration of FIGS. 4 to 6, the turning plates 6-1 and 6-2 are essentially vertical rotation shafts 18 in an essentially horizontal plane. Can be turned around. Therefore, the first turning plate 6-1 is supported on the attached first gantry 82-1 so as to be rotatable about the first rotating shaft 18-1, and the second turning plate 6-2 is Attached to the attached second frame 82-2 is supported so as to be rotatable about the second rotation shaft 18-2. In this case, the first rotating shaft 18-1 passes through substantially the center of the first turning plate 6-1 and the second rotating shaft 18-2 passes through substantially the center of the second turning plate 6-2. . In addition, in the illustrated embodiment, both rotating shafts 18-1 and 18-2 are oriented substantially parallel to each other, as can be seen in particular in FIG. In addition, both racks 82-1 and 82-2 are also pivotable independently of the support member 80, and preferably pass through the support member 80, as seen in FIG. It is supported so as to be able to turn around the coincident rotating shaft 81. On the other hand, in the illustrated embodiment, the support member 80 is fixed so as not to rotate.

  In addition, it should be noted here that, in the illustrated embodiment, both racks 82-1 and 82-2 are disposed on the support member 80 in the vertical direction, as can be seen in FIG. In this case, preferably, the two racks 82-1 and 82-2 are disposed on the support member 80 so as to be adjustable in height.

  In this case, the two racks 82-1 and 82-2 are selectively or additionally provided so that the turning plates 6-1 and 6-2 are positioned on a common horizontal plane as opposed to the views of FIGS. 4 and 6. It is also possible to arrange them relative to each other. The latter is particularly desirable when the exits of the transport paths 2-1 and 2-2 are at the same height, which causes a problem when, for example, the transport paths are opposed to each other.

  Finally, in the illustrated embodiment of FIGS. 4 to 6, the guide element 86 and the gantry 84 that supports the deployment nozzle 88 that is disposed immovably with respect to the guide element 86 are also supported around the rotation shaft 81. The member 80 is supported so as to be pivotable.

  While constructing the apparatus shown in FIGS. 4 to 6, first, the gantry 82-1 and 82-2 are swirled correspondingly depending on the direction of the half-feed paths 2-1 and 2-2. The turning plates 6-1 and 6-2 are adjusted in direction with respect to the exits of the transport paths 2-1 and 2-2, in this case, in particular defined by the respective half-feed paths 2-1 or 2-2 It is moved to a position downstream of the exit of each transport path 2-1 or 2-2 on the transport path. The turning plates 6-1 and 6-2 are then rotated about the attached rotating shaft 18-1 or 18-2, so that in the first path portion, especially as seen in FIGS. An attached curved turning plate 6-1 with no substantial bending and / or substantial twisting of the filter tow strips 4-1 and 4-2 coming from the respective conveying path 2-1 or 2-2 along or 6-2 is moved to a rotational position allowing surface contact to the outer surface. Therefore, the turning of the gantry 82-1 and 82-2 around the rotation shaft 81 turns the turning plates 6-1 and 6-6 in consideration of the arrangement of the conveying paths 2-1 and 2-2 at an angle. 2 is a kind of rough adjustment for adjusting the corresponding direction, but the rotation of the turning plates 6-1 and 6-2 around the respective rotation shafts 18-1 or 18-2 is caused by the respective conveyance paths. The readjustment is performed to accurately adjust the direction of the turning plate with respect to the exit 2-1 or 2-2. This causes the filter tow strips 4-1 and 4-2 to twist along the second path portion between the turning plates 6-1 and 6-2 and the guide element 86, as seen in FIGS. Alternatively, the configuration is adjusted so as to be controlled by twisting. In this case, in the illustrated embodiment, both the rotating shafts 18-1 and 18-2 substantially pass through the second path portion, and therefore, the first rotating shaft 18-1 moves along the second path portion. The first filter toe band 4-1 substantially coincides with the second rotation shaft 18-2 and the second filter tow band 4-2 substantially coincides. In particular, the respective rotation shafts 18-1 or 18-2 substantially pass through the center of the filter tow band 4-1 or 4-2, and substantially coincide with the center axis of the filter tow band. Finally, the adjustment of the configuration is such that a slightly torsionally twisted filter tow band 4-1 or 4-2 is in surface contact with the curved outer surface of the guide element 86, from which essentially further as shown in FIG. It is performed so that it is guided to the filter manufacturing machine 22 along the third path portion without being twisted. In this case, the deployment nozzle 88 acts so that the filter tow strips 4-1 and 4-2 are deployed in a common plane and thus enter the filter maker 22 in an essentially plane configuration.

  Finally, it should be noted that, for completeness, the configuration described with reference to FIGS. 4-6 can be extended to transport and process more than two filter tow bands.
