Description

The invention relates to a swash plate for a conveyor drum of the tobacco processing industry, which is adapted to synchronously co-rotate on a side surface of the conveyor drum for Queraxialen promotion of rod-shaped articles of the tobacco processing industry with troughs for receiving the articles to items in their troughs to move longitudinally axially, wherein the swash plate on a circumferential circle whose radius corresponds to a radial distance of the troughs to a rotational axis of the conveyor drum, has openings which are aligned in the installed state of the swash plate with the wells of the conveyor drum. The invention further relates to a conveyor drum of the tobacco-processing industry with a swash plate according to the invention and a machine of the tobacco-processing industry with a conveyor drum according to the invention.

In the context of the present invention, rod-shaped articles of the tobacco-processing industry are understood in particular to be filter cigarettes, cigarettes, cigarillos, filter rods, etc.

Swash plates are used in machines of the tobacco processing industry on conveyor drums, are conveyed in the arranged along the circumference troughs articles of the tobacco processing industry transversely. The swash plates provide for a longitudinal axial displacement of the articles in their troughs by exerting a mechanical pressure on the front surface of the articles.

A longitudinal axial displacement of the articles in their troughs in the course of their cross-axial promotion may be necessary if they are not in their desired position and should be moved to the desired position. An example of this is given in the preparation of groups of tobacco sticks and filter plugs for wrapping with a glued tipping paper leaflet. In this case, two axially aligned tobacco sticks in the wells of a revolving conveyor, e.g. a rotating drum, transferred. Between the tobacco sticks an axially aligned filter plug twice the useful length is then still stored. In order to ensure a trouble-free storage of the filter plug, located between the tobacco rods and the filter plug of a group distances that must be eliminated by axial displacement of the tobacco sticks, so that the group-forming components of tobacco rods and filter plug are close to each other.

In DE 1 008 173 a suitable displacement mechanism is described, in which so-called wobble rings on a plurality of springs on the hub of a groups promoting the groups in wells drum are attached. At a displacement point actuators press the wobble rings in the direction of the groups, wherein the rings move the outer tobacco rods to the filter plugs located between them. After the shift point, the springs push back the wobble rings, so that after removal of the pushed-together groups new groups of articles can be taken into the hollows. This type of resilient suspension of Verschieberinges on a variety of springs is mechanically sensitive due to the many prone to fracture springs and not trouble-proof especially for high speeds.

According to EP 1 033 083 B1 the wobble ring is further developed in that it consists at least partially of silicone material. The silicone material in particular replaces the feathers according to the state of the art DE 1 008 173 , At the outer end region of the existing silicone swash ring in a training, a pressing ring of a rigid material, for example of metal, is provided, which may have an opening in the region of a trough for receiving an article.

During the assembly of tobacco rod filter plug tobacco rod groups on a conveyor drum or drum, it is possible that one or more consecutive groups may lack a filter plug. In the further process, problems can arise in that if covering paper leaflets are applied to the defective groups despite the absence of filter plugs, disruptions and consequent machine downtime can not be avoided in the subsequent process step, rolling.

To eliminate this problem is out US Pat. No. 3,699,974 (see there Fig. 4 ) known in the manufacture of filter cigarettes, the tobacco sticks of a group in the absence of filter plug while moving on a conveyor drum by blowing together on each other and so to reduce the distance between them. The tobacco sticks are wrapped in a subsequent step with a tipping paper leaflet and then discharged from the production process. The production process does not have to be stopped.

Further disclosed DE 27 42 856 A1 a device for the collapse of tobacco rods in malformed or missing double filters. The device is arranged on a feed drum, wherein the tobacco sticks are not completely blended in the absence of double filter, but on the drum only as far as approached to ensure a sufficient overlap of the subsequently adhered pad paper leaflet.

It is possible to provide the collapse of the tobacco sticks on conveyor drums having swash plates. For this purpose, the swash plates each have a hole or a circular opening at the location of a trough of the conveyor drum, whose diameter is slightly smaller than the diameter of a rod-shaped article and is promoted by the compressed air for pushing the article together. For this purpose, the opening is aligned with the trough, so that an article with the full surface of a compressed air pulse is applied. With usual diameters of the rod-shaped article of about 5 to 9 mm (millimeters), the openings have a diameter of about 3 mm, so that the swash plate fulfills the function of the longitudinal axial displacement of the article despite the opening. Accordingly, the radius or the radial height of the openings with respect to the radial direction of the swash plate smaller than the radius of the articles or the hollows.

It can be very fast switching times for the compressed air pulses reach, so that in individual incomplete article groups only little compressed air hits the swash plate, but this almost completely passes through the opening or the hole. If several incomplete article groups occur in series, it is possible to send a compressed air impulse to each affected article group. However, this becomes difficult with ever-increasing production speeds. On the one hand, the duration of the compressed air pulse can not be arbitrarily shortened, so that a greater proportion of the compressed air can not pass through an opening, but strikes the closed surface of the swash plate. A simpler control of the compressed air pulse looks in this case so that not single compressed air pulses are generated, but a long compressed air pulse, which lasts from the first to the last incomplete article group. A typical pressure of the compressed air used is about 5 bar.

Especially in the latter case, the effect that compressed air meets openings of the swash plate and also on the swash plate itself. This may result in interference of reflected compressed air with subsequent compressed air or pulses of compressed air, and the effectiveness, strength, and direction or concentration of the compressed air or air pulses may deteriorate, resulting in swash plate oscillations. Both leads to an unclean collapse and an unclean tumbling of the swash plate by periodic change in distance between the nozzle and swash ring. Especially at high production speeds, which can currently be between 12,000 and 20,000 items per minute for a production line, this effect can be achieved also not preclude, for example, that a stiffer silicone or elastomer is used in the swash plate.

Based on this prior art, it is therefore an object of the present invention to provide a swash plate, a conveyor drum and a machine of the tobacco processing industry, with which even at high production speeds reliable collapse faulty article groups and a safe and stable tumbling of Swashplate is guaranteed.

This object is achieved by a swash plate for a conveyor drum of the tobacco processing industry, which is adapted to be synchronously co-rotating on a side surface of the conveyor drum for Queraxialen promotion of rod-shaped articles of the tobacco processing industry with troughs for receiving the articles to article in their troughs to move longitudinally, wherein the swash plate on a peripheral circle whose radius corresponds to a radial distance of the troughs to a rotational axis of the conveyor drum, openings, which are aligned in the installed state of the swash plate with the wells of the conveyor drum, characterized in that at least one opening extends circumferentially in the circumferential direction and partially not overlapping formed with a trough and / or at least one additional opening is provided on the circumferential circle, which does not overlap with a trough.

In the context of the present invention, an aperture in the swashplate is aligned with a trough when the aperture formed by the aperture overlaps the circle described by the trough and which, during operation of the conveyor drum, is guided by a rod-shaped article such as a tobacco rod. is completed. A pulse of compressed air through the aperture then hits a front of the article, so that it is displaced in the trough. In the prior art, the apertures are circular and collinear with the axial axis of symmetry of said circle or rod-shaped articles.

According to the invention, it is provided that openings now also completely or partially no longer overlap with the troughs, that is, the circles bounded by the troughs. These openings are thus at least partially outside of the wells, so that compressed air pulses or compressed air does not hit the articles at these points. Since these non-overlapping areas of the openings are provided in addition to the aligned and overlapping openings, the attack surface is reduced, which provides the swash plate the compressed air pulses during the collapse of articles from incomplete article groups. By reducing the attack surface for the compressed air pulse of the compressed air pulse exerts less pressure on the swash plate than before, so that the running and tumbling behavior of the swash plates is controlled. It also reduces the effect that reflected compressed air interferes with subsequent compressed air or compressed air pulses. This measure has no negative impact on the collapse of the articles in the troughs.

Advantageously, the swash plate on an outer ring, in which the openings are arranged.

In the context of the invention, openings are understood as meaning openings in the swashplate or in its outer ring, which are drilled, milled or produced in another way. The height of the openings, viewed in the radial direction of the swash plate, is 2 to 5 mm, preferably 2.5 to 3.5 mm. Also Advantageously, the height of the apertures, where the apertures do not overlap with troughs, is smaller than the height of the apertures aligned with the troughs. This also causes the effect according to the invention, but the structural stability of the swash plate is influenced to a lesser extent. One and the same aperture can have a greater height at the location or in the overlapping area of a trough than in a non-overlapping area.

In a preferred embodiment, at least one aperture aligned with a trough extends beyond the trough in at least one direction along the circumference of the conveyor drum. Preferably, such an opening forms a slot. The slot can be centered on the trough or the trough ahead or run after. In this case, the webs or continuous surfaces of the swash plate between the openings are narrower than in the prior art. The webs provide the structural stability of the swash plate.

The length of the elongated holes in the circumferential direction of the conveyor drum preferably corresponds to the conveying path which the circumference of the drum covers for the duration of a single compressed air pulse at a planned production speed. In this case, the compressed air pulse passes completely through the slot and no pressure is exerted on the swash plate. An advantageous length for a slot is in this context 5 to 15 mm, in particular 6 to 10 mm.

Alternatively or additionally, it is preferably provided that at least one opening has no overlap with a trough. This means that next to the openings at the location of the wells further, separate openings are provided. in this connection is in an advantageous, particularly simple embodiment to circular holes.

An advantageous, easy to manufacture embodiment is that the openings form a regular sequence of equal or equal length openings. By the rule measure is particularly ensured that along the entire circumference of the conveyor drum, the effect of air pressure pulses is the same and does not vary from trough to trough.

A preferred development consists in that a fixed number, in particular 3, openings are arranged between each two successive, aligned with hollows interruptions, which do not overlap with a trough. This embodiment, in particular with three successive separate perforations arranged away from one another, has proven to be particularly reliable in practice.

Alternatively, it is advantageously provided that the openings form an irregular sequence. This means, in particular, that the openings are advantageously of different lengths and / or shapes and / or have different distances. The fact that the arrangement and / or shape of the apertures with respect to the wells of the conveyor drum are irregular, indeed has the consequence that each trough faces a different configuration of openings in the swash plate. However, this irregular configuration prevents the formation of resonances and standing waves, which may affect the operation of the conveyor drum according to the invention under certain circumstances. Even an irregular arrangement of the openings has no negative effects on the collapse of articles of defective article groups, as long as a corresponding opening is arranged at the location of the wells.

Preferably, the outer ring of the swash plate is disposed on an elastic inner ring. The elastic part consists for example at least partially of silicone. It is also possible, a swash plate or a wobble ring on the basis of elastic springs in the sense of DE 1 008 173 equip according to the invention. Such a ring, which is fastened with springs or similar or equivalent elastic means to a hub of a conveyor drum and rotates synchronously with this, is expressly referred to in the context of the present invention as a swash plate.

In the context of the invention advantageously, in particular adjustable, roller device or plunger device is provided, on which the swash plate rolls or along and by means of which the outer ring of the swash plate is pressed at the position of the roller device or plunger device against articles in the wells. It is also advantageously provided that the swash plate is arranged on a hub of the conveyor drum and in particular rotates synchronously therewith. Advantageously, the wells have suction air openings.

The object underlying the invention is also achieved by a conveyor drum of the tobacco-processing industry with a swash plate according to the invention described above and by a machine of the tobacco-processing industry with a conveyor drum according to the invention.

Advantageously, a compressed air displacement device for acting on the end face of an article in a trough of the conveyor drum provided with a compressed air pulse through an opening of the outer ring of the swash plate, and arranged upstream in the conveying direction of the sensor device for detecting the absence of components of the article, in particular filter plug of the tobacco rod filter plug tobacco rod groups, wherein the compressed air displacement device, a compressed air pulse generated when the sensor device generates a signal corresponding to the absence of a component of at least one article. In order to allow for high production speeds, which currently reach up to 20,000 articles of the tobacco processing industry per minute, the sensor device along the conveying direction of the article groups at least 5 troughs upstream of the compressed air displacement device is arranged.

Preferably, the conveyor drum is arranged in the conveying direction of the article upstream of the station for the application of tipping paper leaflets on collapsed tobacco rod filter plug tobacco rod groups.

The object underlying the invention is also achieved by the use of a swash plate in a conveyor drum or a machine of the tobacco-processing industry as described above.

In the drawings, the same or similar elements and / or parts are provided with the same reference numerals, so that apart from a new idea each.

In Fig. 1 a Filteransetzmaschine is shown in fragmentary form in a front view, wherein the Filteransetzmaschine receives over a drum assembly T tobacco sticks double-use length of a schematically drawn cigarette rod machine P. A cigarette rod machine is known under the name "PROTOS" of the patent applicant.

On their conveyor to a compilation drum 21, the tobacco sticks double use length are cut and spread. On the assembly drum 21 are transported over a further drum assembly M double-length filter plugs, which are inserted between two longitudinally spaced tobacco rods. As a result, a sequence of tobacco rod filter plug tobacco rod groups arranged transaxially behind one another is formed on the assembly drum 21.

The assembled article groups are transferred from the assembly drum 21 to a conveyor drum 22 and transported to a padger 10.1 for a first group of assembled tobacco rod filter plug tobacco rod groups. In DE 39 18 137 C2 There is described in detail a coating apparatus which is fully incorporated in the content of the present application.

A glued in the dressing apparatus 10.1 and funded tipping paper strip 11.1 is on a cutting drum 12.1. cut from the blades of a knife drum 13.1 in tipping paper or leaflets. The cut tipping paper leaflets are transferred to the article groups of a first group on the conveyor drum 22 or pinned.

In EP 1 466 535 A1 a method for combining smoking article components is described, wherein in the drawings, articles of a first and second group of products are shown (see. Fig. 2 . Fig. 3 . Fig. 4a, Fig. 4b ). The disclosure of said European patent application is incorporated in full in the disclosure of the present patent application.

After attaching the tipping paper to the article of the first Group the articles of the first and the second group are transported further, wherein the front end of the tipping paper leaflet protrudes on the article groups.

The groups of articles are subsequently conveyed to an application and withdrawal drum 24, so that the article groups not provided with a tipping paper leaflet are removed by the application and removal drum 24 and the front end of the tipping paper leaflets is respectively applied to the articles of the first group. The application and removal drum 24 has thus simultaneously combines the function of a folding star (for the first article groups) and a removal drum (for the second article groups).

The application and removal drum 24 transfers the removed articles of the second group to a conveyor drum 25, which transports the articles of the second group to a coating apparatus 10.2 in which a tipping paper strip 11.2 is conveyed. The second coating apparatus 10.2 has a knife roller 13.2, which cuts the tipping paper strip 11.2 in cooperation with a suction roller 12.2.

The tipping paper leaflets cut from the tipping paper strip 11.2 are transferred and adhered to the tobacco products or tobacco rod filter-tobacco rod groups of the second group. The front end of the tipping paper leaflet is then applied to the articles of the second group on the conveyor drum 25 by means of a folding star 23.2. In this context, expressly Fig. 3 the European patent application EP 1 466 535 A1 referenced, in which this process is shown and described.

The conveyor drum 25 conveys the articles of the second group to a drum 26. The conveyor drum 26 at the same time receives on the conveyor drum 22 further transported article of the first group, so that the articles of the first and the second group are arranged alternately on the drum.

Subsequently, the articles of the first and second groups are transported to a rolling device 27 with a rolling block so that the tipping paper leaflets are completely wrapped around the tobacco rod filter plug tobacco rod groups. The finished wrapped articles are subsequently transferred to a conveyor drum 28 and a further conveyor drum 29 and provided for further processing on a filter attachment machine. In particular, filter cigarettes of simple usable length are produced from the double-length filter cigarettes.

In Fig. 2 a conveyor drum 31 according to the invention is shown schematically in fragmentary perspective view. The surface of the conveyor drum 31 has troughs 32 with Saugluftbohrungen 33, by means of which articles (not shown) are held during their transverse axial promotion in the troughs 32 of the conveyor drum 31. On both sides of the conveyor drum 31 swash plates 34 are arranged, the outer rings 35 have openings 36. The apertures 36 are arranged in a regular concentric arrangement along the circumference of the conveyor drum 31 about a hub of the conveyor drum 31 around. For this purpose, the outer ring 35 of the swash plate 34 is connected via an elastic ring 37 and an inner fastening ring 38 with the hub, so that the swash plate 34 moves synchronously with the conveyor drum 31 or rotates.

The elastic ring 37, which consists for example of silicone, allows the outer ring 35 can be moved relative to the inner fastening ring 38 of the swash plate 34 in the direction of the depressions 32 of the conveyor drum 31. As a result of this mobility, when articles approach the depressions 32, they are displaced longitudinally axially toward the centers of the depressions 32.

Two symmetrically arranged compressed air valves 39 (not shown) on the signal from a sensor device from compressed air pulses from which hit by an aligned with the troughs 32 opening 36 on articles that are held in the troughs 32 of the conveyor drum 31 by means of Saugluftbohrungen 33.

Fig. 3 shows an enlarged detail Fig. 2 in a schematic representation. In particular, the apertures 36 are clearly visible in the outer ring 35 of the swash plate, some of which openings are aligned with the troughs 32 of the conveyor drum 31. The intervening apertures do not overlap with the troughs 32. In the embodiment shown in FIG Fig. 2 and Fig. 3 are located between the openings 36 which are aligned with a respective trough 32 of the conveyor drum 31, three further openings 36, which are aligned with no trough.

In Fig. 4 schematically is a cross-sectional view through the combination of a conveyor drum 41, a swash plate 45 and a combination of compressed air nozzle 47 and compressed air valve 48 is shown. For the sake of clarity, only one trough 42 of the conveyor drum 41 is shown in which an article 43, for example a tobacco stick, is located. Between the conveyor drum 41 and the swash plate 45 there is a gap 44, which indicates that the swash plate 45 is movable toward or away from the conveyor drum 41. The swash plate 45 rotates the conveyor drum 41 together on the compressed air nozzle 47 of the compressed air valve 48 over.

Incomplete article groups, a compressed air stream or compressed air pulse 49 is generated the moment in which trough 42 are aligned with Article 43 and opening 46 with the nozzle 47, which emerges in the direction of arrow from the compressed air nozzle 47 and through the opening 46 on the front of the article 43 meets and this also shifts in the direction of movement of the compressed air pulse 49.

In Fig. 5 is shown in schematic representation a portion of an outer ring 53 of a known swash plate, together with the circumference of a conveyor drum shown with dashed lines 52. At the location of each trough 52 is aligned with the trough 52 opening 54 is arranged by the compressed air pulses in the in Fig. 4 can be routed represented manner.

Sections of the outer rings 56, 57, 59 of swash plates according to the invention are in the FIGS. 6a to 6c shown.

The embodiment according to Fig. 6a has a regular sequence of circular openings 54, 55, wherein in each case an opening or opening 54 is aligned with a trough 52 and two further subsequent openings 55 are aligned with no trough. With the difference that between two recesses 52 aligned with recesses 54 only two instead of three off-side openings 55 are provided, this corresponds to the embodiment of the Figures 2 and 3 , The number of interposed off-site openings depends inter alia on the distance of successive troughs of the conveyor drum.

In Fig. 6b are the successive circular openings 54, 55 detached by slots 58, which are centered in the embodiment shown on the troughs 52 of a conveyor drum. But you can also anticipate or run after the wells, but in any case, the wells 52 still need to be aligned with a portion of the slot 58. This means that in each case a part of the oblong holes 58 overlaps with depressions 52 and at least one other part of the oblong holes 58 does not overlap with depressions 52.

In Fig. 6c an irregular arrangement is shown in which the outer ring 59 to two wells 52 each have a known opening 54, at other wells slots 58 and in between irregularly shaped openings 60. The distances, shapes and sizes alternate in an irregular sequence. In any case, however, no smaller openings than the openings 52 are provided at the locations of the wells. This in Fig. 6c The variant shown has the advantage that no resonances or standing waves can form.

A safe process management and reliable collapse of articles is guaranteed with each of these variants.

All mentioned features, including the drawings alone to be taken as well as individual features that are disclosed in combination with other features are considered alone and in combination as essential to the invention. Embodiments of the invention may be accomplished by individual features or a combination of several features.
