Preferably, the gondolas in the receiving area in a rear region on a stop for, in particular received in the nacelle, rod-shaped article. As a result, a very accurate positioning of the rod-shaped article is possible. In order to compensate for any segment length variations of the rod-shaped article or length variations of the rod-shaped article, the stop is preferably designed to be elastic. In the context of the invention, an elastic training is also a resilient training.

Preferably, at least two suction air openings in the receptacle or in the receiving trough are provided in the receiving area of the receptacle, which are separated from one another by a web. As a result, at least two rod-shaped articles can be separated in the receptacle of the nacelle held each other and safe. Preferably, the receptacle, in particular receiving trough, a contact surface which is aligned with the longitudinal axis and against which a rod-shaped article placed in the receptacle, wherein the web is aligned with the contact surface, such that an inserted into the receptacle rod-shaped article on the web is applied. Preferably, a suction air opening is provided for each rod-shaped article.

For a more accurate embodiment of the Saugluftöffnungen or an inserting a strand machine of the tobacco processing industry with corresponding Saugluftöffnungen in recordings or receiving troughs of gondolas of a loading device is based on the German patent application of the applicant. 10 2016 109 740.3 directed. This patent application was filed on 26.05.2016 at the German Patent and Trademark Office.

Preferably, a receptacle, in particular receiving trough, is provided for rod-shaped articles in the receiving area. The receptacle is preferably part-circular, in particular quarter-circle, in cross section.

Preferably, the stop fills a, in particular upper part of a cross-sectional area of a receptacle in the receiving area. This results in a very gentle transfer of the rod-shaped article from a radial movement to a linear movement, i. in the transfer from the loading device in the strand or on the strand possible. In particular, this results in a low product load. The stop also increases the position accuracy in strand production, especially in the storage in the longitudinal axial conveying process. As a result, a Schnittlageschwank can be significantly reduced.

Preferably, the at least one receiving or receiving trough is arranged parallel to the strand or the format device. Further preferably, a Saugluftvorrat is provided, of which the Saugluftkanäle be fed with suction air. Preferably, a valve is associated with each suction air duct of a nacelle.

Preferably, a strand machine of the tobacco-processing industry is provided with an insertion device according to the invention, by means of the insertion device rod-shaped articles are placed on a formatting device or a conveying device or are placed so that forms a strand of rod-shaped articles.

The object is further achieved by the use of a downstream in the conveying direction of the body part of a nacelle of a loading device of the tobacco processing industry to longitudinally position rod-shaped articles which are arranged in a receptacle of the nacelle following another nacelle. The further nacelle is in the conveying direction of the nacelle below.

Preferably, the positioning is a collapse, wherein in particular a positioning is made up to a stop which is arranged in a rear part of the receptacle.

Finally, the object is achieved by a method for operating a rod making machine of the tobacco-processing industry, wherein rod-shaped articles of the tobacco processing industry are introduced by means of a loading device in a strand of the tobacco processing industry or applied to a strand of the tobacco processing industry, where to insert or applying the rod-shaped articles in the strand or on the strand of the loading device, comprising a plurality of gondolas, which are designed for receiving, for holding and dispensing rod-shaped articles, about a rotation axis is rotated, the gondolas on the way to the strand or at Strand in operative connection with each other in such a way that a rear body part of a downstream in the conveying direction arranged first nacelle moves at least one arranged in a receptacle of the adjacent upstream second nacelle rod-shaped article in its longitudinal axis. The displacement preferably takes place relative to the reception of the second nacelle and / or in the receptacle of the second nacelle.

Preferably, the rod-shaped articles arranged in the second nacelle are displaced up to a rear stop. As a result, a particularly accurate positioning is possible.

Preferably, the receptacles, in particular receiving troughs, of the gondolas are aligned parallel to one another during a rotation of the insertion device. As a result, a particularly accurate and safe transporting and dispensing rod-shaped articles of the tobacco processing industry is possible.

When transferring segment packets or rod-shaped articles of the tobacco processing industry between the drums of a Multifiltermakers it can lead to an easy skipping of the segments or the rod-shaped article to each other. The segment packets or rod-shaped articles or packages of rod-shaped articles which are accommodated in the receptacles of the insertion device, more precisely in the receptacles of the gondolas of the insertion device, can have gaps between the individual rod-shaped articles or segments before being deposited in the strand and are thus in the axial direction, ie in the direction of the longitudinal axis, not necessarily optimally positioned.

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.

Fig. 1 shows schematically a view of a strand machine 21 of the tobacco processing industry. For example, a filter rod machine is shown.

Filter segments 11, 11 'are introduced by means of a transfer device, not shown in troughs or receiving troughs 13 of gondolas 16, 17 of an insertion device 10. The loading device 10 rotates in the direction of the arrow about an axis of rotation 18. The gondolas 17 are each mounted on rotation axes 19, so that upon rotation of the loading device 10, the orientation of the receiving wells 13 remain the same, in particular parallel to the formed strand 12 or a web of Format device 22.

The recorded in the gondolas 17 filter segments 11, 11 'are passed longitudinally to a strand 12. For this purpose, the filter segments 11,11 'on a wrapping material strip 35, which is applied to a format tape 34, placed. The format belt 34 moves in the direction of the arrow or in the conveying direction 15. In Fig. 1 is the conveying direction 15 from right to left by the format device 22, so that in the formatting device 22, a wrapping material strip 35 is wound around the strand 12, as usual, provided with an adhesive and is closed.

Subsequently, the strand 12 is cut by a cutting device 33 in filter rods desired use length, for example, twice the length of use.

The loading device 10 according to the invention has specially designed gondolas 16, 17. These are in the FIGS. 2 to 5 shown schematically. The gondolas 16, 17 are conveyed in the conveying direction 15 on the loading device 10, which is shown only in sections. In addition, the gondolas 16, 17 are arranged so close to one another that a rear part 24 or 24 'of a leading nacelle 16 can penetrate into a receiving region 14 of the following nacelle 17. As a result, the filter segments 11, 11 'accommodated in the receiving region 14 or the receiving trough 13 of the nacelle 17 can be positioned by axial displacement. To make this possible, the nacelle bodies 26, 27 have a rear body part 24, 24 ', which is designed so far downstream that they can penetrate into the receiving region 14.

In the Fig. 2 to 5 only two gondolas 16, 17 of the loading device 10 are shown. This serves to illustrate the principle of the positioning of filter segments 11, 11 '. Of course, more gondolas 16, 17 are usually provided for the loading device 10, since the filter segments 11, 11 'are to be positioned continuously in the respective gondolas.

In Fig. 2 and also in the Fig. 3 to 5 are at upstream gondolas 17, the filter segments 11, 11 'still included in the receiving trough 13. During further conveyance in the direction of arrow 15, the filter segments 11, 11 'approach a wrapping material strip 35, which is also conveyed in the conveying direction 15. It then happens a transfer, approximately in a range between the arrangement of the two gondolas 16, 17 from the Fig. 2 to 5 happens. The left side arranged gondola 16 is again arranged away from the filter segments 11, 11 '. These have already been applied to the filter strand 12 or form a total of the filter strand 12th

The illustrated filter segments 11, 11 'may be filter segments 11, 11' made of a filter acetate tow or hollow filter. The hollow filters are marked with 11 '. However, completely different filter segments can also be provided. In order to provide an exact positioning of the filter segments 11, 11 'in the rear region 28, 28' of the gondolas 16, 17, corresponding stops 25, 25 'in the receiving areas 14 and receiving wells 13 are provided. These limit the axial displaceability of the filter segments in the receiving troughs 13. This is for example in the Fig. 3 to 5 shown. In Fig. 3 the stop 25 or 25 'is not flexible or elastic. The flexibility or elasticity is however in Fig. 4 intended. In this way, corresponding length tolerance of the filter segments 11, 11 'can be compensated, so that it is avoided that too long filter segments 11, 11' or a total too long group of filter segments 11, 11 'jump out of the receiving trough 13 when pushed together.

In FIGS. 2 and 3 the rear body parts 24, 24 'of the gondolas 16, 17 are not elastic or flexible. This is, however, in Fig. 4 and especially in Fig. 5 the case. In particular in Fig. 5 is the rear body part 24, 24 'of the gondolas 16, 17 each elastic, in particular resilient in this case, designed. Also, the stop 25, 25 'may be resilient.

The stop 25, 25 'also serves to prevent slippage in the longitudinal axial direction during transfer from the rotational movement of the insertion device 10, in particular a loading wheel, in a longitudinal axial conveying direction, ie in the longitudinal axial conveying direction of the strand. It can also be provided that the stop 25, 25 'at the transport in the receiving troughs 13 of the gondolas 16, 17 has a distance from the rod-shaped articles. The stop 25, 25 'is in this case formed in the radial direction so that it covers less than half the radius of a rod-shaped article. This is in Fig. 6 shown schematically. As a result, excessive radial kinetic energy which is exerted on the product end, ie on the rod-shaped article in the rear region, is avoided.

Fig. 6 schematically shows a cross section through the lower part of a nacelle 16, 17 according to the invention with a view of the rear part 24, 24 'of the nacelle 26 of the invention. A receiving trough 13 is formed, which has a stop 25 in the rear part 24, 24'. The receptacle 13 is designed substantially in a quarter-circle, so that of the rod-shaped articles which are received in the receptacle 13, a quarter circle from the circumference of the nacelle 26 is applied. The stop 25 covers or fills only a part of the cross-sectional area of the receptacle 13. In Fig. 6 the stop 25 is formed only in an outer edge region. The radial extension of the stopper 25 is only a fraction, in particular less than half, preferably less than a quarter, preferably less than a sixth, of the radius of the receptacle 13 or of the male rod-shaped article to be accommodated.

The boundary edge of the stop 25 in the receptacle 13 is shown bent convex.

In Fig. 7 a slightly different embodiment of the stopper 25 is shown schematically. The edge of the stop 25 is limited by straight lines. In addition, approximately half of the surface of the receptacle 13 is filled by the stop 25.

Due to the design of the stopper 25 according to the 6 and 7 the engagement of the stop on the rod-shaped articles is completed shortly after delivery of the rod-shaped article in the transfer to the strand or to the strand, so that a very gentle transfer is possible. Overall, the product load is kept to a minimum.

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. In the context of the invention, features which are identified by "particular" or "preferably" are to be understood as optional features.
