Description

The invention relates to a receiving device for receiving articles of the tobacco processing industry for a conveyor device designed to convey these articles, which has a movable body in the conveying direction, with at least one adapted to the format of the male article receiving portion for receiving at least one article. Furthermore, the invention relates to a conveying device for conveying articles of the tobacco processing industry with at least one such receiving device.

Articles of the tobacco processing industry, for example, rod-shaped objects such as tobacco rods and sticks of limited length, filter rods, filter rod groups or cigarettes with and without filters or cigarillos u. Like. Be.

In the conveying device of the type mentioned, the transport of the articles of the tobacco-processing industry takes place by means of the movable body provided as a conveying element, which moves with its outside receiving the article in the direction of movement and thus in conveying or transporting direction emotional. For this purpose, the articles are received on the outside of the movable body one behind the other in the direction of movement and extending transversely to the direction of movement receiving portions. During transport, the receiving portions are connected to a negative pressure source via passages formed in the movable body, so that the articles to be conveyed are sucked by a negative pressure formed in the receiving portions toward the outside of the movable body of the conveyer and are carried along thereby the receiving portions are formed in particular groove-shaped.

Preferably, as a conveying device of the aforementioned type, a rotary conveying device is used, in which the movable body is designed as a rotatably mounted, driven drum in order to convey the articles of the tobacco processing industry in the rotational direction, thus defining the direction of movement. Such conveying devices and in particular rotary conveying devices are used in drum machines of the tobacco processing industry, in particular in filter attachment machines and Multifilterherstellmaschinen.

Conveying devices and in particular rotary conveyor devices for conveying articles of the tobacco processing industry are known. For example, the WO 2010/012420 A1 a conveyor drum with receiving troughs for receiving articles of the tobacco processing industry. The receiving troughs comprise two different types of receiving troughs, namely smaller receiving troughs for receiving rod-shaped articles with a smaller diameter and larger receiving troughs for receiving rod-shaped articles with a larger diameter. The two different receiving troughs on the outside of the drum body of the conveyor drum in a row are arranged transversely and alternately one behind the other, based on the rotation and thus conveying direction.

For the production of articles of the tobacco processing industry with different formats, in particular different diameters, the corresponding formatrelevanten components of a used for this purpose Machine, in particular the conveyor devices of the type mentioned to adapt to a changed format, which is often associated with high costs and long downtime and resulting high costs.

It is therefore an object of the present invention to propose measures, whereby the adaptation of a conveyor device to articles of different formats and in particular different diameters is facilitated.

This object is achieved with a receiving device for receiving articles of the tobacco processing industry for a conveying device designed for conveying these articles, which has a movable body in the conveying direction, with at least one adapted to the format of the male article receiving portion, characterized by at least one receiving element, the one outer side, on which the at least one receiving portion is formed, and an inner side, with which the receiving element is to be arranged on the outer side of the movable body of the conveying device, and fastening means for releasably securing the at least one receiving element on the outer side of the movable body the conveying device are formed and have at least one position-giving element which is provided on the receiving element and adapted for engagement with the movable body of the conveying device.

Characterized in that according to the invention, the receiving portions for receiving the articles are not formed directly on the outside of the movable body of the conveyor, but on the outside of receiving portions to be arranged with its inside on the outside of the movable body of the conveyor, and fastening means are provided, allow a releasable attachment of the receiving elements on the outside of the movable body of the conveyor, the movable body of the conveyor can be equipped with interchangeable format-dependent recording elements. For an exact positioning of the receiving elements on the outside of the movable body of the conveying device, the fastening means according to the invention comprise at least one position-indicating element, which is provided on the receiving element and is designed for engagement with the movable body of the conveying device. Thus, the invention enables in a structurally simple and at the same time effective a fast format and in particular diameter change.

Thus, whereas in the prior art the receiving sections, which are generally provided with a hollow shape, are formed directly on the outside of the movable body of the conveying device, which is generally provided as a drum, this is precisely not the case with the invention. For in the invention interchangeable receiving elements are provided to form the receiving portions, so that at least in a preferred embodiment of the invention, the receiving portions are formed exclusively on the outside of the receiving elements. This in turn allows a simplified and standardized production of the movable body of the conveyor.

The replacement of only the receiving elements instead of the entire conveyor allows faster implementation not only a format change, but also a maintenance or repair and thus leads to lower downtime and a reduction in costs, especially since the inventive arrangement of the receiving elements requires a significantly lower material usage than the remaining components of the conveyor.

Finally, another advantage of the invention is that a conveying device provided with the receiving device according to the invention can also interact with other components of a machine of the tobacco-processing industry like conventional conveying devices. Therefore, it is possible to replace in conventional machines of the tobacco processing industry conventional conveyors against conveyors with the receiving device according to the invention and in this way to be able to use the advantages of the invention in already existing machines of the tobacco processing industry.

Preferably, a format-independent body is used as the movable body of the conveying device, whereby the pitch accuracy is predetermined in the arrangement of several recording elements.

Furthermore, it is conceivable to provide not only at least one position-giving element on the receiving element, but at least one further position-giving element on the movable body of the conveying device, wherein the at least one position-giving element on the receiving element and the at least one position-giving element on the movable body of the conveying device respectively engage with each other to bring.

A precise positioning of the receiving elements on the movable body is particularly important if the recording of the articles to be conveyed in the receiving sections by negative pressure and therefore in the receiving element at least one suction channel is included, which opens on the outside of the receiving element in the receiving portion and also on the Inside the receiving portion ends where the suction channel must be brought into fluid communication with a correspondingly associated suction channel in the movable body of the conveyor. However, such a fluid connection can essentially only be produced by precise alignment of the receiving element with respect to the movable body of the conveying device, if appropriate using suitable sealing elements.

In addition to the at least one position-generating element, which ensures by engagement with the movable body of the conveying device for an accurate positioning of the at least one receiving element, the fastening means may also have further elements which result in a releasable fixing of the at least one receiving element on the movable body of the conveying device contribute, but it is irrelevant whether these additional means make a direct engagement between the at least one receiving element and the movable body of the conveyor or support the fixation only indirectly by being interposed so to speak between the receiving element and the movable body. It is crucial that using the at least one position-giving element an immediate fixation of the at least one receiving element on the movable body of the conveying device is achieved.

Further preferred embodiments and advantageous developments of the invention are specified in the dependent claims.

A preferred embodiment of the invention is characterized in that the at least one positional element arranged on the receiving element pin for the insertion into a trained on the movable body of the conveyor, essentially correspondingly accurate bore, formed on a receiving element precisely fitting bore for receiving a movable Body of the conveying device arranged pin or a screw for screw engagement with a formed in the movable body of the conveyor, complementary threaded bore formed on the receiving element projection for engagement with a substantially correspondingly accurate recess in the movable body of the conveyor, a recess formed in the receiving element Recording a provided on the movable body of the conveying device, substantially correspondingly precisely fitting projection and / or a locking means for engaging with the b ewegbaren body of the conveyor device has provided corresponding locking means. According to this embodiment, therefore, position-giving elements can be realized with a particularly simple and thus cost-effective but effective construction.

Furthermore, the fastening means preferably comprise clamping means, screw connection means and / or magnetic connection means. The use of such fasteners allows a particularly secure mounting of the at least one receiving element on the movable body of the conveyor and at the same time allows a quick and easy change of the receiving element. When using clamping means and / or magnetic connecting means, the change of the receiving element can be carried out easily even without further tools.

Depending on the geometric and material design of the receiving element and the movable body of the conveyor, the fastening means be provided either on the receiving element or on the movable body of the conveyor or on both.

A further preferred embodiment is characterized in that the position-indicating element has a stopper provided on the receiving element or a section of the receiving element provided as a stop and for a contact engagement with a stop provided on the movable body of the conveying device or a section of the movable body provided as a stop the conveyor device is formed.

This embodiment is particularly advantageous for the case that the fastening means comprise sliding means for a sliding engagement with corresponding, preferably substantially complementary, sliding means formed on the movable body of the conveying device. By means of the stop or the stops namely during the attachment of the receiving element by sliding the sliding movement is stopped at a point in which then the desired exact positioning of the receiving element relative to the movable body of the conveyor is reached. In particular, in the event that the receiving element consists of an elongated body, along which the receiving portion extends, and for attachment to the movable body of the conveying device in the longitudinal direction can be pushed onto this, the stop should be designed as acting in the longitudinal direction of the receiving element stop.

In a development of the previously discussed embodiment, the sliding means have at least one key formed on the receiving element for the sliding engagement with a formed on the movable body of the conveyor, corresponding, preferably substantially complementary, fitting groove and in particular two formed on the receiving element, spaced apart and substantially parallel to each other extending feather keys for the sliding engagement with two correspondingly formed on the movable body of the conveyor fitting grooves. Alternatively, it is also conceivable that at least one fitting groove on the receiving element and the at least one Provide complementary key on the movable body of the conveyor.

Furthermore, the fastening means may preferably comprise at least one connecting means with which at least two receiving elements can be brought into engagement in such a way that they occupy a defined distance from one another. By means of the connecting means a plurality of receiving elements can be combined into a kind gurt- or chain-like arrangement, whereby these receiving elements are held together, while the fixation relative to the movable body of the conveyor using the fasteners and in particular the at least one position-generating element substantially directly on the movable body Conveying device takes place. Thus, in this embodiment, the connecting means contribute to a defined arrangement of each two adjacent receiving elements and in particular determine the division in the group of interconnected receiving elements. In addition, can be achieved with an arrangement of interconnected by the connecting means receiving elements better handling during format change over the change of individual receiving elements.

Preferably, the at least one connecting means is designed to connect a plurality of receiving elements with each other so that they are arranged equidistant from each other and therefore each receiving element has the same distance from the adjacent receiving element.

The distance between two adjacent receiving elements from each other, for example, can be substantially zero. This is the case in particular when the connecting means are formed on the receiving element as a hinge means for substantially direct articulated coupling of two adjacent receiving elements with each other. In this embodiment, therefore, the receiving elements are adjacent to each other and form a kind of articulated chain.

Alternatively, it is also possible to achieve a greater pitch, to choose between each two adjacent receiving elements a distance greater than zero. This is the case, in particular, when the connecting means are designed as connecting links in order to couple two adjacent receiving elements, preferably articulated, to one another and to arrange them at a defined distance from one another. In this embodiment, therefore form the links together with the receiving elements a kind of chain.

In a further alternative embodiment, the connecting means are also formed as links, which, however, each support a receiving element and are coupled via the respectively adjacent links, preferably articulated. Here, therefore, only the links form a kind of chain and serve as support elements each for a receiving element.

Furthermore, it is alternatively possible to form the at least one connecting means band, cord or wire, in order in this way to connect the receiving elements loosely to a kind of belt with each other, wherein such a connection is articulated at the same time. For this purpose, the receiving elements, preferably on or adjacent to one of their side edges, at least one bore and / or at least one eye through which or extends the band, cord or wire-shaped connecting means.

In a further preferred alternative embodiment, the at least one connecting means on a support for receiving the receiving elements. Accordingly, in this embodiment, the receiving elements are connected to each other via the carrier by the individual receiving elements are applied substantially accurate pitch on the carrier. By such a carrier, the receiving elements are held together, while the fixation using the fastening means and in particular of the at least one position-generating element takes place directly on the movable body of the conveyor.

Preferably, the carrier should be a, preferably flexible, flat part. The flat part may in particular be formed as a foil or sheet and preferably consist of textile material, plastic and / or metal.

The fastening means may additionally be provided for fixing on the outside of the movable body of the conveying device and, if necessary, have special fastening elements. For example, if the carrier consists of a ferromagnetic metal strip, magnets can be used to hold the metal strip.

The fastening means may also comprise retaining means for supporting the receiving elements on the carrier in order to achieve the desired cohesion of the receiving elements on the carrier. Preferably, the holding means on the underside of the receiving element, preferably on or adjacent to one of its side edges, a projection and the carrier have a corresponding opening for receiving such a projection, so by engagement of a projection in a corresponding, preferably substantially accurate, opening the desired orientation of the associated receiving element relative to the carrier is achieved.

Preferably, the receiving portions form elongate grooves or troughs, which are oriented substantially perpendicular to the direction of movement.

The at least one receiving element may preferably consist of plastic. However, other materials are conceivable for producing the at least one receiving element.

In a preferred embodiment, the receiving device according to the invention is intended for a conveying device provided for conveying the articles and designed as a rotary conveying device, in which a rotatably mounted drum is provided as the movable body, the direction of rotation of which defines the conveying direction.

A group of receiving elements interconnected by means of the aforementioned connecting means may preferably be closed to form a ring. Also, the aforementioned carrier may form a ring. Such a ring can then be easily pushed onto the drum of the conveyor and can preferably be centered over a fit on the drum of the conveyor and aligned by means of fixing means such as a pin on the drum.

However, since it is not possible on each drum to subtract a closed ring readily, the ring can consist of at least two releasably interconnected ring segments for a quick format change.

Finally, another aspect of the present invention relates to a conveying device for conveying articles of the tobacco processing industry with at least one receiving device according to the present invention.

It should first be noted at this point that the same or similar elements in the figures are identified by the same reference numerals, so that in the following description after an initial explanation of those elements of a corresponding repeated explanation is omitted.

The preferred embodiments of a receiving device for receiving articles of the tobacco processing industry described below with reference to the figures are intended for a conveying device for conveying these articles, which is designed as a rotary conveying device and a has conventional structure. For this purpose, the conveying device has a drum body forming a conveyor drum or a base drum 2, which has a substantially cylindrical outer or outer surface 2a and within a drum machine of the tobacco processing industry, in particular in a filter manufacturing machine or Filteransetzmaschine to a likewise not shown axis of rotation is rotatably mounted. The conveyor drum is rotated by a drive, also not shown in rotation, wherein the rotational direction of the outer side 2a of the base drum 2 defines the aforementioned direction of movement and thus the conveying direction of the article, also not shown, to be conveyed.

According to the in the FIGS. 1 to 3 shown first preferred embodiment, the outer side 2a of the base drum 2 is provided with a circumferential rim 4, in which extending in the axial direction, elongated recesses 6 are formed, which are arranged in the circumferential direction next to each other in series and equidistantly from each other. As the FIGS. 1 and 3 can also be seen, open into this recess 6 suction channels 8, which are connected to a suction source, not shown.

For receiving the articles, depression elements 10 are used according to the embodiments described here. These tray elements, which are separate components, in the illustrated embodiments have an elongated shape and, in particular, the Fig. 2 and 4 can be seen, a directed transversely to its longitudinal direction concave surface to form a trough 10 a, in each of which a rod-shaped article of the tobacco-processing industry is taken, which is not shown in the accompanying figures. The trough elements 10 are arranged on the outer side 2a of the basic drum 2 so that their upper side forming the trough 10a points outwards, as can be seen from the figures.

The articles accommodated in the troughs 10a are held in the embodiments described here by means of a vacuum generating suction air. In particular Fig. 1 can recognize this, the trough elements 10 are provided with corresponding passages 12, which the Outside 2a connect the base drum 2 facing inside of the trough elements 10 with the outside thereof, where the trough 10a is formed, so that the passages 12 open into the respective trough 10a. The trough elements 10 are to be arranged on the outer side 2a of the basic drum 2 so that their passages 12 are aligned with the suction channels 8, respectively.

Thus, a precise positioning of the trough elements 10 on the outer side 2a of the base drum 2 is required. For this purpose, position-giving elements are provided. As the FIGS. 1 and 3 can recognize, according to the first preferred embodiment, the position-bearing elements include holes 14 in the recesses 6 in the ring 4 on the outer side 2a of the base drum 2 and are on the outer surface 2a of the base drum 2 facing bottom or inside of the well elements 10 corresponding pins 16th attached, in such a way that with the arrangement of the trough elements 10 each in a recess 6 of the ring 4 on the outer side 2 a of the base drum 2 each a pin 16 is inserted accurately into an associated bore 14, such as Fig. 3 schematically shows. With the aid of the described connector, the depression elements 10 can thus be positioned in the desired position relative to the outside 2a of the base drum 2, in particular to bring the passages 12 in alignment with the suction channels 8 in the base drum 2.

In order to prevent inadvertent release of the depression elements 10 from the base drum 2, the described connector should preferably be press fit by selecting the outside diameter of the pins 16 to be slightly larger than the inside diameter of the holes 14 and the portion of the base drum 2 surrounding the holes 14. or the pins 16 are made of at least slightly elastic material, or be formed as not shown in the figures locking connection by the pins 16 are provided with a radial locking lug and the holes 14 with a corresponding lateral recess or vice versa. Alternatively, it is also conceivable, for example, to choose a magnetic connection by the magnets of the in Fig. 3 shown pins 16 formed and the associated holes 14 are enclosed by ferromagnetic material, which incidentally also in the reverse arrangement is possible. As a further alternative in this context, however, it is also conceivable to arrange a magnet in the bores 14 or to fill the bores 14 with magnetic material and to provide the hollow elements 10 with ferromagnetic material on their bottom or inside.

Instead of a pen form as described above, the in Fig. 3 schematically illustrated elements 16 may also be formed as projections with other shapes, provided that these projections fit into the respective corresponding bore 14 substantially fit exactly whose shape must be correspondingly complementary.

Furthermore, it is alternatively also conceivable, instead of in Fig. 3 schematically shown pin connection 14, 16, for example, to choose a screw, so that instead of the in Fig. 3 shown pin 16, the trough element 8 is provided with a (not shown in the figures) through hole through which a threaded screw is inserted, which then comes into threaded engagement with a correspondingly formed in the bore 14 internal thread into screw engagement.

Finally, other mounting options for the Muldenelemente are conceivable, if the fasteners are solvable. Because for a quick format change, the arrangement of the trough elements 10 on the base drum 2 should be interchangeable, so that only trough elements 10 are provided with troughs 10 a different curvature and width.

As the Figures 1 and 2 can also be seen, in the illustrated first embodiment, the well elements 10 are dimensioned so that they fit into the recesses 6 in the rim 4 on the outside 2a of the base drum 2 substantially. Further, in the illustrated embodiment, the axial length of the trough elements 10 corresponds approximately to the axial length of the recesses 6. Because of the equidistant arrangement of the axially aligned recesses 6 on the circumference of the base drum 2 in the illustrated first embodiment, the pitch accuracy is given by the base drum 2, which thus also can be called format constant.

Fig. 4 shows one opposite the FIGS. 1 to 3 slightly modified second embodiment in which on the pin 16, an elastic O-ring 18 is seated, which is held in a pin 16 surrounding the groove 20 and in the assembled state of the trough element 10 from the wall 14a of the bore 14 projecting shoulder 14b engages behind. As a result, a releasable locking connection is generated. For the sake of completeness, it should be noted at this point that, alternatively, the O-ring can also be fastened to the wall 14a of the bore 14 and engage in an associated suitable groove corresponding to the groove 20 on the pin 16 of the depression element 10. Of course, the described arrangement is dimensioned so that the trough element 10 rests with its lower or inner side 10b on the bottom 6a of the recess 6, when the O-ring 18 is in clamping engagement with the shoulder 14b, as Fig. 4 also shows.

In Fig. 5 a third preferred embodiment is shown in which as a position-giving element on the outer side 2a of the base drum 2, a peripheral peripheral radial shoulder 22 is provided. This paragraph 22 serves as a stop for a frontal end 10c, which comes in arrangement of the trough elements 10 on the base drum 2 in abutment with the shoulder 22 and thus also forms a stop in the form of an abutment. Such an arrangement is particularly suitable if, for attachment in the recesses 6 or on the rim 4 and thus on the outer side 2 a of the base drum 2, the well elements 10 along their long sides each have a feather not shown in the figures, whereby two in the axial Direction parallel to each other, not shown in the figures keyways are formed. Accordingly, in the recesses 6, two spaced-apart, extending in the axial direction of the fitting grooves formed, with which the feather keys can be brought into sliding engagement on the trough element 10. For mounting in this embodiment, the trough elements 10 are thus mounted by sliding into the recesses 6 on the outer side 2 a of the base drum 2, until they come with their (during pushing forward) frontal end 10 c into contact with the shoulder 22. Incidentally, it is also conceivable in this case to form the fitting grooves on the depression element 10 and the feather keys in the recess 6.

Fig. 6 shows a fourth preferred embodiment, in which the trough elements 10 are connected by links 24 hinged together. The connection of the well elements 10 takes place at the front ends 10c through the links 24. For this purpose, the links 24 are articulated at their two ends in each case via a hinge 26 with the front end 10c of the adjacent tray element 10, such as Fig. 6b lets recognize. For this purpose, as in Fig. 6a is shown, in the front ends 10c of the well elements 10 corresponding hinge holes 26a provided that record as part of the hinges 26 provided, not shown in the figures hinge pins. By serving as connecting means links 24 thus a substantially direct and distance-free articulated coupling each two adjacent well elements 10 is provided, whereby the adjacent well elements 10 form a kind of articulated chain or band. As Fig. 6a can also be seen, the thus interconnected trough elements 10 are closed to form a ring which is pushed onto the lateral surface or outer side 2a of the base drum 2.

In Fig. 7 a fifth preferred embodiment is shown, in which the trough elements 10 are also arranged directly under articulated connection and thus without spacing, but the articulated connection takes place between each two adjacent trough elements by means of a hinge pin 28 which connects the two adjacent trough elements 10 directly articulated. For this purpose, the long sides 10d are formed with a plurality of respectively spaced-apart fingers 10e, which engage in the spaces between the fingers 10e on the long side 10d of the adjacent tray element 10 and at their free ends in the figures, not shown, aligned holes, through which the hinge pin 28 is plugged, like Fig. 7b can be seen, in which the parallel to the long sides 10d of the trough elements 10 and thus with respect to the base drum 2 extending in the axial direction and shown in dashed lines hinge axis for simplicity is also designated by the reference numeral "28".

Fig. 8 shows a sixth preferred embodiment, in which each two adjacent well elements 10 similar to the fourth preferred embodiment of FIG Fig. 6 are coupled by links 30 articulated together and the connection of the links 30 takes place with the trough elements 10 respectively via hinges 32, the hinge axes in the direction of the longitudinal extent of the trough elements and thus in the direction of which long sides and with respect to the base drum 2 in the axial direction. However, unlike the fourth preferred embodiment, the links 30 have a greater length, whereby each two adjacent well elements 10 are kept at a distance from each other. In this way, a larger division can be achieved. In this embodiment, therefore, form the trough elements 10 together with the links 30 a kind of chain.

Especially in the case of the Fig. 6 to 8 discussed fourth to sixth embodiments, the well elements 10 are arranged, so to speak, in the manner of chain links, the well elements 10 may alternatively be referred to as well members.

Also, the links 34 according to the in Fig. 9 illustrated seventh preferred embodiment keep the well elements 10 at a distance from each other. However, in this embodiment, the articulated connection takes place exclusively via the links 34. As Fig. 9a can recognize the links 34 have a fork shape with a longer rod-shaped portion 34a and two spaced-apart fingers 34b, on the inner sides of two opposing locking lugs 36 are formed. At the free end of the rod-shaped portion 34 a, the link 34 is provided with a slot 37. For a hinged coupling that includes a link 34 with its two fingers 34 b, the free end of the rod-shaped portion 34 a of an adjacent link 34, whereby the locking lugs 36 loosely engage on the inner sides of the fingers 34 b in the slot 37 of the adjacent link 34. Further, in this embodiment, the well elements 10 and the links 34 are configured so that the well elements 10 are supported by the links 34. For this purpose, the links 34 with their rod-shaped Section 34a inserted through formed in the well elements 10 corresponding through holes 10f, which are oriented transversely to the longitudinal extent of the well elements 10 and thus in the assembled state transverse to the axis of rotation of the base drum 2. In the illustrated embodiment, two correspondingly spaced through holes 10 f are provided on each well element 10, such as Fig. 9b lets recognize. In Fig. 9c the arrangement of the links 34 described above is shown on the trough element 10, while Fig. 9d the coupling of the links 34 shows. Here are the links 34 and in particular the length of the rod-shaped portion 34 a dimensioned so that also in this embodiment, the well elements 10 are each held at a distance from each other, as well Fig. 9d lets recognize. Accordingly, here form only the links 34 a kind of chain, which is also joined together to form a ring here.

Fig. 10 shows schematically with reference to Fig. 8 described sixth preferred embodiment, a special arrangement of the well element 10 on the outer side 2a of the base drum 2, this particular arrangement, for example, in principle for the fourth, fifth and seventh preferred embodiments according to the FIGS. 6 . 7 and 9 applies. In the presentation of Fig. 10 Namely, at the lower or inner side 10b of the trough elements 10, a preferably circumferential sealing element 38 is mounted, with which the trough element 10 rests on the outer side 2a of the base drum 2. As a result, the undesired entry of secondary air into the respective suction channel 8 in the base drum 2 is prevented.

In Fig. 11 an eighth preferred embodiment is shown in which the trough elements 10 are connected by a cord or a wire 40 with each other. For this purpose, the cord or wire 40 is pulled by trained at the front ends 10c of the trough elements 10, not shown in the figures eyes or holes. In this way, the trough elements 10 are connected to a kind of belt, which is joined together in this embodiment to form a ring. It should be noted in this context that, despite the guidance of the cord or wire 40 along both frontal ends 10c of the trough elements 10 in FIG illustrated embodiment, however, is only a single continuous line or a single continuous wire 40, the or in the region of his or her sections 40a changes the page. Due to the articulated connection by means of a cord or a wire 40 a better handling over the change of individual well elements is achieved in Formatwechsei.

Fig. 12 shows a ninth preferred embodiment in which the individual well elements 10 are connected by a strip or strip-shaped carrier material 42 with each other. As Fig. 12 can recognize the carrier material 42 is designed as a flat part and joined together to form a ring. Preferably, a metal strip can be used as a carrier material 42. But there are also other materials, such as textiles or plastic, especially in the form of a plastic film, conceivable. The individual well elements 10 are in this case graduation applied to the substrate 42 and using position-giving elements, as for example with reference to FIGS. 1 to 4 have been described, positioned on the outside 2a of the base drum 2. If the carrier material 42 consists of a sheet-metal strip, magnets may be provided for fixing the carrier material 42; However, other mounting options are just as conceivable.

In Fig. 13 a tenth preferred embodiment is shown, in which, in the same way as in the ninth embodiment according to Fig. 12 a carrier material 42 is used. However, in this embodiment at the front ends 10c and / or the lower or inner side 10b of the trough elements 10 in the direction of the base drum 2 facing projections 44 are formed, which protrude in the assembled state through corresponding openings 46 in the substrate 42. This arrangement of projections 44 and corresponding openings 46 can serve for example for fixing the depression elements 10 relative to the support material 42. At the same time or alternatively, the projections 44 can also be used for fixing the depression elements 10 to the base drum 2 by engagement with recesses provided on the upper side 2a and not shown in the figures.

In Fig. 14 An eleventh preferred embodiment is shown, which differs from the first embodiment according to Fig. 1 differs in that instead of a ring 4, a format ring 50 is provided, which is pushed onto the lateral surface or outside 2a of the base drum 2. Similar to the wreath 4 of Fig. 1 the format ring 50 has a plurality of axially extending and circumferentially juxtaposed elongated recesses 52 in which the (in Fig. 14 not shown) Muldenelemente 10 are releasably secured. Thus, the format ring 50 forms a format constant component similar to the wreath 4 of Fig. 1 , In particular, the format ring 50 is centered on the outer surface 2a of the base drum 2 via a fit, which is not shown in the figures, and aligned in exact position over at least one position-giving element. This ensures that formed in the format ring 50 suction holes 48 are brought into alignment with correspondingly associated and formed in the base drum 2 suction channels. Further leaves Fig. 14a Recognize a circumferential circumferential stop 22 to which the format ring 50 comes into contact when pushed onto the base drum 2, whereby an accurate positioning in the axial direction is ensured. A rotationally fixed attachment of the format ring 50 to the base drum 2, for example, by means of magnets in the stop 22 or by screwing done.

Since it is not possible on each conveyor drum to deduct a closed ring forward, it is alternatively also conceivable that in Fig. 14 divided format ring 50 into a plurality of releasably interconnected ring segments, as in Fig. 15 is shown by reference numerals "50a", "50b" and "50c". In this case, the ring segments 50a to 50c can be exchanged individually for fast format change.

Finally, it should be pointed out again at this point that the positioning of the depression elements 10 takes place by means of position-determining elements provided for this purpose, which produce a direct engagement with the base drum 2. In contrast, for example, serve in the FIGS. 12 and 13 shown carrier material 42 and in the Figures 14 and 15 shown format ring 50 or 50a, 50b, 50c only as a kind of belt or band to hold together the trough elements 10 in the manner of a rope ladder. It is also conceivable for fastening the carrier material 42 or the format ring 50, for example, to use suitable clamping elements. In contrast, as already mentioned, the positioning and thus adjustment relative to the outer side 2a of the basic drum 2 takes place by means of position elements acting directly on the basic drum 2; this will also be in Fig. 14b illustrates that at the side edge of the format ring 50, a recess 54 is incorporated, which is aligned in the assembled state with an associated hole in the base drum 2, which the bore 14 of Fig. 1 and 3 corresponds and therefore also in Fig. 14b designated by the reference numeral "14".
