  The problem underlying the present invention is therefore to provide a further device of the type described at the outset, in which a quick and simple adaptation is carried out for different filter rod lengths. Should be possible.

This challenge is
A device for the transport of rod-shaped articles, in particular filter rods, in the tobacco processing industry,
A transport device for transporting these items in the longitudinal axis direction;
A lateral transfer device comprising means for transporting these items in the horizontal axis direction; and
Having a turning device for coupling the conveying conduit with the lateral transfer device;
This direction change device converts the movement of these items in the longitudinal axis direction into the direction of conveyance in the horizontal axis direction in the area of the direction change zone,
In this case, the lateral transfer device has at least one end-side longitudinal guide device for at least one head end of a rod-shaped article,
In the above type of device, this device is
This is solved by an improvement in that the drive is provided for a longitudinal guiding device for at least one head end of a rod-shaped article.

In particular, the longitudinal guide device of the lateral transfer device is equipped with one position adjustment device on each side of the head end of a rod-shaped article guided in the transverse direction, and therefore both of the longitudinal guide devices are The flow of single-layer items is facilitated between the direction guide devices.
It is likewise possible for this lateral transfer device to be provided with only one position adjustment device, with which it is possible for one longitudinal guiding device to automatically, for example, a rod Position adjustment during format exchange, such as changing the rod length of the shaped article, and within the spacing of the position adjustment device, adjusted relative to the relative longitudinal guide device; That is adapted.

  With the position adjustment device according to the invention for the longitudinal guide device, a simple, quick and particularly automatic adjustment of the distance between both longitudinal guide devices is achieved in the lateral transfer device. For this purpose, it is no longer necessary for the operating personnel to adjust the spacing of these longitudinal guides in a manual manner, for example during format changes. Overall, the adaptation time is reduced by the above.

  In addition, automatic spacing adjustment provides a precise position between both longitudinal guides. This longitudinal guide device is used for example in which a diverted, longitudinally conveyed item is moved further from the conveying conduit in the transverse direction by means of a transverse transfer device in the transverse direction, for example rollers and And / or further transported in the transverse direction by means of a belt, so that the flow of single-layered goods formed in this transverse transport device is transported, for example, into a magazine or the like. Known devices for transporting rod-shaped items with transport conduits transporting in the longitudinal direction and suitable lateral transport devices are, for example, filter receiving stations in cigarette continuum machines, whereby The filter rod is continuously fed to the filter rod magazine of the filter mounting machine.

  To that end, the lateral transfer device further comprises two longitudinally movable guides on the end face side, which are movable relative to each other and adjustable relative to each other, on both heads of the rod-shaped item. Have for the end.

  In order to achieve a predetermined guide of the flow of a single-layer item in the transverse transfer device, two end position abutments are also provided for this longitudinal guide device, or for each longitudinal guide device. A reciprocating movement of the longitudinal guide device is possible between these end position abutments in a direction transverse to the conveying direction of the goods flow, in particular perpendicular to this conveying direction. And position adjustment is performed.

  In yet another embodiment, the longitudinal guiding devices are or are adjustable in the opposite direction or symmetrically with one positioning device or one positioning device with respect to each other.

  At least one drive device, in particular a pneumatic drive device (pneumatic cylinder) or a servo drive device, is provided as a position adjusting device, with which at least one longitudinal guide device is used for conveying goods. Can be moved or moved transversely, in particular perpendicular to the direction, or with this drive, the distance between these longitudinal guides or the preset distance between these longitudinal guides It is furthermore advantageous if they can be adjusted or adjusted with respect to each other. For example, a stepless position adjustment of the distance between the two longitudinal guides is achieved via a position-controlled servo drive.

  Furthermore, it is advantageous if the length of the reciprocating movement of this longitudinal guide device or both longitudinal guide devices can be adjusted laterally and positionally with respect to the conveying direction of the goods.

  In particular, at least one linear guide part formed transversely to the transport direction of the laterally transported goods is provided for this longitudinal guide device, or both longitudinal guide devices, This achieves a predetermined linear position movement of the longitudinal guide device in the lateral transfer device.

  Advantageously, this longitudinal guide device or both longitudinal guide devices of the transverse axial transfer device are formed as guide rails or guide surfaces along the conveying direction of the goods conveyed in the horizontal axis direction. Has been.

  Advantageously, in the region of the turning zone at the end of the conveying conduit carrying in the longitudinal direction, the turning device is formed as a wedge-shaped turning member. Furthermore, it is advantageous if the direction changing device is designed to be movable in the longitudinal direction with respect to the goods conveyed in the longitudinal axis direction.

  A further simplification of the automatic adjustment, for example during format exchange at the filter receiving station, is achieved when at least one drive is provided for the longitudinal position movement of the turning device. For example, the position drive can be realized by a position-accurate servomotor or likewise by a pneumatic cylinder.

  In particular, the length of the longitudinal position movement of the turning device is adjustable or adjusted.

  This device is further characterized in that the length of the longitudinal position movement of the turning device corresponds to the magnitude of the reciprocation of this longitudinal guide device or of both longitudinal guide devices. By virtue of the above, adaptation to different filter rod lengths is achieved in a simple manner, without the need for the operator to make adjustments in the conveying device in a manual manner.

  Advantageously, the conveying device according to the invention is also provided on the inlet side in a filter rod magazine, in particular in a filter rod magazine of a machine in the tobacco processing industry, or in a transport facility in the tobacco processing industry.

  Furthermore, the object of the present invention is solved by a machine in the tobacco processing industry or a transport facility in the tobacco processing industry, which is formed with the apparatus described above for transporting rod-shaped articles in the tobacco processing industry. Is done. To avoid repetition here, reference should be made explicitly to the embodiments described above.

Please refer to these figures clearly for details according to the invention.

  In the following figures, the same or similar elements, or corresponding members, are indicated with the same reference numerals, respectively, so that the appropriate updated concept is not questioned.

  In FIG. 1, a plan view of a conveying device 1 for a rod-shaped article of the tobacco processing industry, in particular a filter rod, according to the invention is schematically illustrated. In this case, the receiving station receives, via the guide track, a filter rod that now reaches the pneumatic conveying conduit of the delivery station (not shown). These movements of the filter rod in the longitudinal axis direction are converted into transport movements in the horizontal axis direction in the direction change zone 8.

  With regard to further details of the receiving station, European Patent 0 699 396, in which a double receiving station is described in detail in the examples, which is based on a sufficiently broad basis in the disclosure of the present invention. See (Patent Document 3). The description for this dual receiving station also applies in a corresponding manner to this receiving station illustrated in FIG.

  After individualization of the filter rods by corresponding pairs of rollers in the conveying conduits conveying in the longitudinal direction, these accelerated filter rods reach the turning zone 8. The transport direction of the filter rod transported in the longitudinal axis direction in the transport device 1 is indicated by an arrow directed to the left side.

  In the direction change zone 8, the movement of the filter rod in the longitudinal axis direction is changed to the movement in the horizontal axis direction. For this purpose, a transport belt part (Foerderbandabschnitt) having a longitudinal guide 17 with a wedge-shaped turning member 18 is connected to the transport conduit. This longitudinal guide 17 is open towards the lateral transfer device. The filter rods redirected from the longitudinal movement of the filter rods by the wedge-shaped redirecting member 18 reach the range of action of the transverse transfer roller pairs and are , Pressed in the transverse direction into the transverse transfer section 22, so that these filter rods are captured by a belt (not shown here) and into a schematically drawn filter rod magazine 24. It is conveyed.

  The lateral transfer section 22 is laterally limited by two longitudinal guide rails 30, 31, which are narrowed towards the longitudinal guide 17 in the open area, As a result, the opening region is widened.

  On the side of the frame support, two drive devices 41, 42, 43, 44 are provided for the respective guide rails 30, 31, so that these guide rails 30, 31 are arranged in the lateral transfer section. It can be moved in a direction perpendicular to the conveying direction of the flow of the single-layered goods in 22. In this case, the distance between the guide rails 30 and 31 in the region of the guide surface oriented in parallel is adjusted to the length of the filter rod conveyed in the horizontal axis direction in the connection portion in the opening region.

  As the drive devices 41, 42, 43, 44, position-accurate servo drives and pneumatic cylinders are suitable, so that the distance between the guide rails 30, 31 can be determined in an automatic manner without manual intervention by the operator. Can be adjusted.

  The guide rails 30, 31 are symmetrical with respect to the intermediate position of these filter rods in the transverse transfer section 22 when the filter rods transported in the transport conduits vary, i.e. when the filter rod length varies. And are adapted to the length of these filter rods. In addition to the position movement of the guide rails 30 and 31, at the same time, the wedge-shaped direction changing member 18 is also moved correspondingly by the length of this position movement. For this purpose, a drive 19 is also provided in the longitudinal guide 17, for example in the form of a pneumatic cylinder 19, for moving the longitudinal position of the wedge-shaped turning member 18.

  When the pneumatic cylinder 19 is activated, the wedge-shaped turning member 18 is reciprocally moved between the two abutments 20 and 21 correspondingly. In this case, the pneumatic cylinder 19 is connected to the wedge-shaped direction changing member 18 via an appropriately shaped piece. By appropriate switching of the pneumatic cylinder 19, the wedge-shaped diverting member 18 is correspondingly reciprocated or slid.

  In addition, suitable linear guides are provided for these guide rails, which are formed perpendicular to the transport direction of the goods transported in the lateral transport section 22, and thereby provide the guide rails 30. Or 31 is similarly adjusted between the contact parts linearly. For this purpose, a contact strip 35 having contact portions 36, 37 is provided in the center of the lateral transfer section 22. These contact portions 36 and 37 form one (first) terminal position of the above-described linear reciprocating motion of the guide rails 30 and 31.

  In the other end position, the guide rails 30, 31 are moved outwards, and therefore the position adjusting bolts 38 are oriented and arranged outwardly in the vertical direction along these guide rails 30, 31. Is obtained when it contacts the side contact portions 45, 46 on the outside.
