Description

The invention relates to a transfer drum of the tobacco processing industry for Queraxialen promotion of two streams of rod-shaped products of the tobacco processing industry.

Out WO 03/024256 A2 a device for assembling groups of filter segments for the production of multi-segment filters of the tobacco processing industry is known, are assembled in the filter segments and promoted cross-axial. The assembled groups of filter segments or sub-groups of filter segments are transferred by a transfer device into a longitudinally axially conveyed strand of filter segments, which is then wrapped by a wrapping material, so that forms a corresponding filter strand in a strand process. Subsequently, corresponding multi-segment filters are cut to length from the filter strand in order to be further processed accordingly. For example, multi-segment filters become twice the useful length cut to set between two tobacco sticks and then cut centrally to form two filter cigarettes. By using a plurality of self-contained functional units, which are designed as modules, a large variability in the production of multi-segment filters is given.

A corresponding device is also in the EP 1 393 640 B1 disclosed. Here, in particular, the assembly is shown in the transverse axial conveying the filter segments and the longitudinal axial conveying in the strand production.

To accelerate multi-segment filter production, in EP 1 913 824 A1 . EP 1 913 825 A1 and EP 1 767 107 A1 proposed to make the strand formation two lanes. In this case, different concepts are used for the precise positioning of the section of the strand for the production of the multi-segment filters from a string of corresponding filter segments. EP 1 913 824 A1 discloses, for example, means for controlling the position of the segment filter groups of the strand relative to the cut of the cutting means. The means in this case comprise control means with a sensor which is arranged in the vicinity of each continuous filter strand and monitors the passage of at least one filter element of each group. If there are deviations, the speed of a format strip, by means of which the filter strand is conveyed, is adapted accordingly.

EP 1 913 825 A1 go another way. In this case, before the introduction of a group of filter segments into the strand or the strands, the position of the filter segments is varied longitudinally axially on the basis of a measurement signal taken after the formation of the filter strand. EP 1 767 107 A1 sees a change in the phase of the insert wheels in Dependence of the position of the segments in the filter strand.

Out EP 1 787 534 B1 For example, a multi-segment filter machine is known which has a rotary member which rotates about an axis which is aligned transversely to channels of an inlet finger and is provided with a plurality of carriers which serve to mount groups of filter plugs in pairs of conveyors to pass the two channels to form two continuous successions of groups in the channels. This device is relatively poorly visible in the field of transfer of the filter plug on the rotary member.

As a result, a very good visibility into the device when transferring or transferring filter segments or groups of filter segments in two strands, which are conveyed longitudinally axially given.

Another advantage of the device is that in the transverse axial promotion of the filter segments or groups of filter segments prior to transfer into two longitudinally axially promoted strands compared to EP 1 787 534 B1 only half the process speed is necessary. This is due to the fact that preferably two groups of filter segments, of which one group in the first filter strand is inserted longitudinally and the other in the second filter strand is inserted longitudinally axially, in particular in a trough one behind the other or side by side, namely in the transverse axial transport , There are thus two webs of groups of filter segments, which are used to form two longitudinally axially funded filter strands, transversely promoted.

From the transfer drum 8, the rear web 64 is transferred from filter segment groups to a double transfer drum 10. This is schematically in Fig. 3 also indicated, wherein the rear part of the transfer drum 10 accommodates the respective filter segment groups 13b. The other web 65 of filter segment groups 13a is transferred via a take-off drum 9 to the front part of the double transfer drum 10. The front part and the rear part of the double transfer drum 10 rotate opposite to each other, so that the respective filter segment groups 13a and 13b can be securely transferred to the insert wheels 11 and 12.

The insert wheels 11 and 12, which are arranged in this example V-shaped, whose axes or axes of rotation 92, 93 to each other thus have an angle of about 70 °, each have Einlegeradaufnahmearme 41, which also have corresponding wells into which the Filter segment groups 13a and 13b can be inserted accordingly. The insert wheels 11 and 12 are rotated at a rotational speed which is slightly greater than the conveying speed of the filter strands 14a and 14b. For position control of the filter segment groups in the filter rod 14a and 14b, the rotational speeds of the insert wheels are variable.

In the embodiment according to Fig. 2 it is a variant of the transfer of filter segment groups or filter segments from the group forming device 2 in filter strands 14a and 14b.

The corresponding transferred filter segment groups 13a and 13b, which form a filter strand 14a and 14b, have been correspondingly placed on a wrapping material strip, not shown, for example, each of a format strip, the in Fig. 3 is shown schematically, is driven. Subsequently, the filter strands are guided in the conveying direction 24 through a formatting device 17, in which the wrapping material strips are wound around the respective filter strands 14a and 14b and glued. Thus, wrapped filter strands 15a and 15b are formed. These are cut in the cutter 18.

The cutting device 18 is, for example, a rotating knife. As a result, multi-segment filters 16a and 16b are cut to length corresponding to the filter strands 15a and 15b. These are then transferred by a transfer device 19 of the prevailing in the strand forming device 3 longitudinal axial conveying direction in a transverse axial conveying direction 24. In the transfer device 19 may be a two-lane so-called spider of the Applicant, which is common in two-lane cigarette rod making machines.

From the transfer device 19, the multi-segment filters 16a and 16b are arranged transaxially one behind the other on a measuring drum 20, in or on which a sensor device 23 is arranged.

After measuring the multi-segment filters 16a and 16b, those which are defective are discharged in the discharging drum 21. Those who are okay will be over the delivery drum 22 delivered.

The measuring device or sensor device 23 generates, inter alia, a measuring signal 28 which is fed to a regulating device 27. The measuring signal 28 may contain, for example, an indication as to how far the position of one or more filter segments deviates from a desired and predeterminable position. From this signal 28 and / or from measurement signals 71a and 71b, which are provided by sensors 70a and 70b, corresponding control signals 30 and 31 are generated, which are supplied to the drives 25 and 26 of the insert wheels 11 and 12. As a result, preferably the speed of insertion of the filter segment groups 13a and 13b can be controlled. The control device 27 can generate a control signal 29, which drives the drive of the cutting device 18.

In Fig. 1 In addition, in the case of the corresponding sensors 70a and 70b between the two filter strands 15a and 15b, a lighting device 32 'is provided, by means of which electromagnetic radiation is radiated in the direction of the two strands 15a and 15b in order to detect correspondingly in the transmitted light method, where the respective position of the filter segments or groups of filter segments in the filter string 15a and 15b, respectively. The electromagnetic radiation is visible light, infrared light or ultraviolet light. Instead of detection with electromagnetic radiation, a capacitive measurement can also be carried out if, for example, filter segments have activated charcoal granulate or are acetate filter segments loaded with activated charcoal. The sensor devices 70a and 70b may alternatively be provided to the sensor 23 or cumulatively.

For the sensor device 23, this applies alternately to multi-segment filters 16a and 16b from the strands 15a and 15b measures, so that always alternately measuring signals to the respective layers of filter segments or groups of filter segments in the multi-segment filter of the control device 27 are supplied. The control signals 30 and 31, which are supplied to the drives 25 and 26 of the insert wheels 11 and 12, can now be used to change the position of the filter segments or groups of filter segments, for example to perform a cut as simultaneously as possible on both filter strands 15a and 15b can and thus transfer the multi-segment filters 16a and 16b in approximately a transverse axial alignment with each other on the discharge device 4. Alternatively, a device may be provided on the discharge device 4 in order to transfer non-aligned multi-segment filters into cross-axially aligned multi-segment filters. For this purpose, for example, find a stop in example of the measuring drum 20 use.

For example, in Fig. 3 schematically in three-dimensional representation of a further device for transferring a stream of cross-axially funded filter segments or groups of filter segments, which are arranged axially axially behind each other in the transverse axial conveying, shown in two longitudinally axially promoted strands of filter segments or groups of filter segments. Also, two webs of filter segment groups 64 and 65 are conveyed from the transfer drum 5 to the transfer drum 6 and another transfer drum 6 '. These two tracks 64 and 65 then arrive in the embodiment of Fig. 3 as in the embodiment according to Fig. 2 From there, the filter segments or groups of filter segments of the webs 64 and 65 are removed from a transfer drum 8 and the front Track 65 and the filter segment groups of the front track 65 passed to the loading wheel 12. The filter segments or groups of filter segments of the rear web 64 are still transferred to a pickup drum 9 and from there to the Einlegead 11. The Einlegeradaufnahmearme 41 of the insert wheels 11 and 12 and also the Einlegeads 91 of the following embodiments, for example, as in EP 1 639 907 B1 the applicant. Correspondingly cranked guides can be provided for this purpose, so that the receptacles of the Einlegeradaufnahmearme 41 and 41 'are each arranged parallel to each other on the conveying path. In Fig. 3 are schematically shown the axes of rotation 92 and 93 of the insert wheels 11 and 12.

In the embodiment of Fig. 3 replace the transfer drum 8 and the pickup drum 9, the double transfer drum 10 of Fig. 2 ,

In particular, the embodiments according to the FIGS. 1 to 3 The insertion wheels, which may also be referred to as transfer devices, are arranged in a V-shape, can also efficiently serve to longitudinally axially conveyed strands 14a and 14b of rod-shaped articles 13a and 13b into one or two streams cross-axially promoted rod-shaped article to transfer. This can in particular also serve to transfer tobacco strands or tobacco sticks from a longitudinal axial conveying direction into a transverse axial conveying direction. For this purpose, the tobacco strands should be cut before transferring them into rod-shaped articles, for example tobacco sticks, and then the tobacco sticks themselves are removed from the insertion processes 11 and 12 from the longitudinally conveyed tobacco strands and onto the transfer drums 8 and 9 according to FIG Fig. 3 or on the transfer drum 10 according to Fig. 2 be transferred.

Fig. 4 shows a further embodiment of the device. In this embodiment, separation of the webs 64 and 65 is performed directly after the transfer drum 6. There are namely two pickup drums 9 and 9 'are provided, which, as in Fig. 4 1, remove the filter segment groups 13a and 13b of the front panel 65 and the rear panel 64. These transfer the filter segment groups of these two webs on receiving arms 84 and 85 of an accelerator drum 80. The accelerator drum 80 has in each case two accelerator drum rings 83 and 83 ', which respectively have a plurality of receiving arms 84 and 85. The receiving troughs, which are provided for receiving the filter segment groups 13b of the front track 65, perform a circular movement whose diameter is smaller than that of the receptacles which are provided for receiving the filter segment groups 13a of the rear track 64. The difference of the radii of these circular paths corresponds to the distance of the filter strands 14a and 14b formed.

The insert wheels 11 and 12 are provided in this embodiment with a collinear axis of rotation 92 to 93. The insert wheel 11, which is provided for the formation of the filter strand 14a, has a larger radius than the insert wheel 12, which is provided for the formation of the filter strand 14b. Accordingly, the Einlegeradaufnahmearme 41 'and the receiving troughs of the Einlegeradaufnahmearme 41', by a distance closer to the axis of rotation of the accelerator drum 80 is arranged, which corresponds to the distance of the formed filter strands 14a and 14b. In this way, an efficient transfer of the filter segment groups 13a and 13b can be performed from a single side, wherein the insert wheels 11 and 12 can still be driven independently of each other. This is a particularly clear and well-visible embodiment the invention.

In Fig. 5a another embodiment is shown in a schematic three-dimensional representation. The same design is in Fig. 5b shown schematically in a frontal view. The webs 64 and 65 of filter segment groups are respectively transferred from the transfer drums 5 and 6 to an accelerator drum 7. From there, the two webs 64 and 65 of filter segment groups 13a and 13b pass onto a transfer drum 90 having two drum rings 88 and 89 whose axes of rotation and their orbital axes 114 and 115 are offset from each other, in particular offset in the direction of the double loading wheel 91 In this way, when the filter segment groups are transferred, the desired spacing of the receiving troughs 62 and 63 provided on each double receiving arm 87 is made possible. The corresponding receiving trough 60 of the receiving arms 86 of the rear drum ring 88 is also in accordance with Fig. 5b clearly shown. In addition, the receiving wells 61 of the front drum ring 88 are correspondingly in Fig. 5b well depicted. By this placement or transfer of filter segment groups 13a and 13b on the double insert 91 is also given a very good visibility in the transfer. Alternatively, the rear drum ring 88 may comprise receiving arms 86 that are designed to be movable, movable or movable radially outwards, so that when the filter segment groups 13b are transferred from the accelerator drum 7, the receiving recess of the receiving arm 86 provided for this purpose is longitudinally aligned with the adjacent receiving recess of the drum ring 89 is. In this case, the axes 114 and 115 should be on top of each other.
