The invention will be described below with reference to bags 10 for receiving tobacco. In the Fig. 1 to 24 shown pouch 10 are made of thin packaging material, in particular (thermally sealable) film formed. The bag 10 consists of a one-piece, here rectangular, elongated blank, which forms a pocket 11 due to folding of a leg for the package contents with pocket front wall 12 and pocket rear wall 13. These adjacent portions of the blank are joined together by thermal welding or gluing , and in the area of side seams 14, 15. An opening is used to fill the bag 11 and to remove the contents.

The bag rear wall 13 is extended beyond the opening and forms a bag flap 16. This bag is wrapped around it with the bag 11 filled, such that an end portion of the bag flap 16 abuts the bag rear wall 13 and is connected thereto. The bag flap 16 extends when the bag 10 is closed both on a front side 17 and a rear side 18 of the bag 10.

The bag 10 is provided with glued (separate) blanks. In the present example, as a closure means of the bag 10, a blank in the form of a tape 19 at the free edge of the bag flap 16 - approximately centrally - attached. The strip-shaped closure means has a coating of permanent adhesive on one side and an adhesive-free grip tab 20 on the free end region.

Furthermore, in this example, the bag 10 another blank attached, namely a (control) Bandole 21. The band 21 is positioned like the tape 19, but not centrally, but laterally adjacent and spaced from the tape 19. In addition, are 22 health warnings), namely in the area of the bag back wall 13, the inside of the bag flap 16 and the outside of the bag 16. The health advice 22 is large-scale printing according to the respective legal requirements, such as a Combination of textual warnings and pictures.

Another peculiarity of the bag 10 shown is that the bag flap 16 is lengthened relative to the bags known in the prior art. Usually, the bag flap 16 ends approximately halfway up the pocket front wall 12 or the bag back wall 13. However, in the present case, the bag flap 16 is extended approximately into the area of the transition between the front 17 and the back 18 of the bag 10 extends both the tape 19 and the handle tab 20, starting from the back 18 into the region of the front side 17. The two blanks thus extend beyond an imaginary bag edge between the two opposing large-sized side surfaces.

Both blanks (tape 19 and banderole 21) are arranged on the bag flap 16 such that a first section 23 of the blank is respectively attached to the bag flap 16 and projects beyond an edge 24 of the bag flap 16. A second portion 25 of the blanks projects beyond the edge 24 and is wrapped around the imaginary edge of the bag. In the present case, the handle tab 20 is formed at the end of the second portion 25 of the tape 19.

The attachment of the blanks will be described below with reference to two embodiments of packaging machines.

• Fig. 4 zeigt einen Teil einer Verpackungsmaschine in einer Seitenansicht, die zum Anbringen der Zuschnitte an befüllten Beuteln 10 dient. In einem ersten Arbeitsschritt wird eine fortlaufende Materialbahn 26 für das Tape 19 von einer Bobine 27 abgewickelt und über diverse Umlenkrollen 28 in den Bereich einer Schneideinrichtung 29 geführt. Dort werden einzelne Tapes 19 von der fortlaufenden Materialbahn 26 abgetrennt und an eine Auflegetrommel 30 übergeben.

First embodiment:

• Fig. 4 shows a part of a packaging machine in a side view, which serves for attaching the blanks to filled bags 10. In a first step, a continuous web of material 26 for the tape 19 is unwound from a reel 27 and guided over various pulleys 28 in the region of a cutting device 29. There, individual tapes 19 are separated from the continuous material web 26 and transferred to a lay-up drum 30.

With the help of the laying drum 30, the tapes 19 are transferred to the bag 10. This takes place in such a way that only the first section 23 of each tape 19 is attached to a respective bag 10 so that the second section 25 projects beyond the free edge 24 of the bag flap 16 ( Fig. 5 ).

During the attachment of the first portion 23 of the tape 19, the bag 10 lies flat on a conveyor belt 31, with which the bags 10 are conveyed through the device. The bags 10 are arranged with their longitudinal direction in or parallel to the transport direction pointing to the conveyor belt 31. Each side of the transport belt 31 guides 32 are provided at the height of the bag 10. Transverse to the transport direction, the bags 10 are each positioned between carriers 33 of the transport belt 31.

According to the position of the bag 10 on the conveyor belt 31, the separated tapes 19 are placed with their longitudinal extent pointing transversely to the transport direction on the bags 10.

Following the laying drum 30, the bags 10 pass a pressing device 34 for pressing the first portions 23 of the tapes 19 against the top of the bag 10. In the present embodiment, the pressing device 34 is formed by a arranged above the transport path foam roller 35, the rotating at one Axis 36 is mounted. With the aid of the foam roller 35, the first portion 23 is pressed against the top of the bag 10, so that a glue connection between the tape 19 and the bag flap 16 is established.

The necessary glue can be applied on site with a glue unit on the tape 19 or the web 26. Alternatively, pre-glued material webs 26 can be used. Optionally, the glue can be reactivated when attaching the tape.

In a next processing station in the region of the transport belt 31, the second portion 25 of the tape 19 in a transfer station 37 is wrapped around the bag 10 and following the contour of the bag 10, the latter is pressed into the region of an underside of the bag 10.

For this purpose, the bags 10 are laterally or transversely to the transport direction partially deported from the transport belt 31 to expose the bottom of the bag 10. In order to prevent the bags 10 from slipping off the side of the transport belt 31, a support surface 38 for the bags 10 is positioned in this area at the level of the upper side of the transport belt 31.

For lateral pushing off, a slider 39 arranged next to the transport belt 31 is used, which in the region of a contact surface for engagement with the bag 10 is designed substantially complementary to the contour of the bag 10, namely with an approximately trapezoidal recess.

As a counterpart to the slider 39, a stationary guide 40 is arranged on the opposite side, which has a corresponding contact surface, so that the bag 10 can be held between the contact surfaces of the slider 39 and the guide 40.

In the area of the top of the bag 10, a hold-down 41 is provided, with which the bag 10 is pressed against the transport belt 31, so as to secure the position of the bag flap 16 against displacement when a tape 19 is attached. The hold-down 41 is mechanically coupled to the slider 39 in the present embodiment and is moved accordingly along with these. Not only is pressure exerted on the bag 10 from above, but the hold down 41 also aligns the bag flap 16, particularly with respect to the side edges of the bag 10. Furthermore, the hold down 41 holds the bag flap 16 in the aligned position.

The actual process of flipping the second portion 25 of the tape 19 is effected by means of a separate member, namely by means of a pressing device 42. The pressing device 42 has a pressure roller 43 which is rotatably mounted on an arm 44.

The pressure roller 43 is movable on the arm 44 by a gear, not shown, as follows: When a bag 10 reaches the Umlegestation 73, the pressure roller 43 is above the bag 10 and laterally offset thereto, namely above and at a distance to the second portion 25 of the tape 19. After the lateral displacement of the bag 10 according to Fig. 7 the pressure roller 43 is moved in a pivoting movement of the contour of the bag 10 following, under entrainment or under application of the second portion 25 of the tape 19 on the circumference of the bag 10 accordingly Fig. 7 and 8th , In this case, the pressure roller 43 is guided into the region of an underside of the bag 10 in order to press and secure the second portion 25 of the tape 19 here as well.

So that the pressure roller 43 can fix the tape 19 to the bag 10 as described, a recess 45 in the lateral guide 40 is provided on the one hand in the working area of the pressure roller 43, and a corresponding recess in the bearing surface 38.

After folding over the second section 25 of the tape 19, the bag 10 is pushed back again into its original relative position on the conveyor belt 31, namely by means of laterally pivoting guides 40 (FIG. Fig. 9 , below).

As it turned out Fig. 9 Furthermore, the guide 40 and the slide 39 extends approximately over the length of a bag 10. The slide is mounted on two push rods 46 and hydraulically, mechanically or pneumatically actuated.

In the next step, the bands 21 are placed. The banderoles 21 required for this purpose come from a banderole magazine 47, from which the banderoles 21 are removed one by one and at a distance from one another are transferred to the periphery of another laying drum 48. During the transport of the banderoles 21 on the laying drum 48 glue is applied to the banderoles 21 with a glue nozzle 49 and these are placed on the bag 10 by the laying drum 48. As in the case of the tapes 19, this takes place only with a first section 23, whereas a second section 25 of the bands 21 protrudes freely beyond the edge 24 of the bag lugs 16.

Thereafter, the bags 10 reach the area of another transfer station 50. Also in the transfer station 50, as in the transfer station 37, a slide 39 and a hold-down 41 are arranged on one side of the transport belt 31, which are used as in the transfer station 37. On the opposite side of the transport belt 31, however, no guide 40 or a pressure roller 43 is provided, but a combination of two fittings 51, 52nd

The two shaped pieces 51, 52 are mounted displaceably on a vertical guide 53 and movable independently of each other. For this purpose, push rods 54 serve, which are articulated on the one hand to a frame 55 and on the other hand to the fittings 51, 52 are mounted. The shaped pieces 51, 52 each have a contact surface 56, wherein the two contact surfaces 56 together correspond approximately to the contour of the bag 10.

• Zunächst befinden sich beide Formstücke 51, 52 oberhalb des seitlich auskragenden zweiten Abschnitts 25 der Banderole 21 (Fig. 11).
• Danach werden beide Formstücke 51, 52 abgesenkt, wobei eine hervorstehende Nase 80 des unteren Formstücks 52 den zweiten Abschnitt 25 der Bobine 21 mitnimmt. Die Formstücke 51, 52 werden soweit abgesenkt, dass sich die Kontaktflächen 56 auf Höhe der entsprechend gekrümmten Abschnitte der Oberseite und der Unterseite des Beutels 10 befinden (Fig. 12).
• Danach wird wie in Fig. 13 gezeigt der Beutel 10 seitlich mittels des Schiebers 39 verschoben und gegen die Kontaktflächen 56 der Formstücke 51, 52 gedrückt, wodurch der zweite Abschnitt 25 der Banderole 21 am Beutel 10 befestigt wird.
• Danach werden entsprechend Fig. 14 die Formstücke 51, 52 auseinanderbewegt, sodass der Beutel 10 mit der daran befestigten Banderole 21 in Transportrichtung des Transportgurts 31 abtransportiert werden kann.
• Danach werden die beiden Formstücke 51, 52 in die Ausgangsstellung gemäß Fig. 11 bewegt, bevor der nächste Beutel 10 die Umlegestation 50 erreicht.

The procedure for transferring the second section 25 of the band 21 is as follows:

• First, both shaped pieces 51, 52 are located above the laterally projecting second portion 25 of the band 21 (FIG. Fig. 11 ).
• Thereafter, both fittings 51, 52 are lowered, with a protruding nose 80 of the lower mold 52, the second portion 25 of the reel 21 entrains. The fittings 51, 52 are lowered so far that the contact surfaces 56 are at the height of the corresponding curved portions of the top and bottom of the bag 10 ( Fig. 12 ).
• After that, as in Fig. 13 shown the bag 10 laterally displaced by the slider 39 and pressed against the contact surfaces 56 of the fittings 51, 52, whereby the second portion 25 of the band 21 is attached to the bag 10.
• After that will be accordingly Fig. 14 the shaped pieces 51, 52 moved apart, so that the bag 10 can be removed with the banderole attached thereto 21 in the transport direction of the transport belt 31.
• Thereafter, the two fittings 51, 52 in the starting position according to Fig. 11 moves before the next bag 10 reaches the folding station 50.

Thus, the lower mold 52 can be brought to rest in the region of the bottom 10 of the bag, the conveyor belt 31 is provided in the working region of the lower mold 52 with a recess 57.

As Fig. 10 shows, two fittings 51, 52 are provided so that either the band 21 left or right of the tape 19 can be attached.

Furthermore, it is conceivable that in the method step according to Fig. 13 , Thus, when pressing the second portion 25 of the banderole 21, the two fittings 51, 52 still (slightly) against each other to be pressed to press the banderole 21 in total against the bag 10.

After attaching the banderole 21, the bag 10 are pushed back laterally onto the conveyor belt 31, for example, by a corresponding switch or laterally pivoting guides.

A special feature of the method described so far is also that the conveyor belt 31 is cyclically driven, wherein the two Umlegestationen 37, 50 during the (short-term) standstill of the transport belt 31 are active while the two Auflegetrommeln 30, 48 the tape 19 and Place banderole 21 during transportation of transport belt 31.

• Das zweite Ausführungsbeispiel steht im Zusammenhang mit einem speziellen Beutelrevolver 58 gemäß DE 10 2012 003 400 A1 aus dem Hause der Anmelderin. Zur vollständigen Offenbarung der Erfindung wird auf den Inhalt dieser Anmeldung verwiesen, die vollumfänglich zum Gegenstand der vorliegenden Anmeldung gemacht wird.

Second embodiment:

• The second embodiment is in connection with a special bag turret 58 according to DE 10 2012 003 400 A1 from the house of the applicant. For a complete disclosure of the invention, reference is made to the content of this application, which is fully made the subject of the present application.

• In der Übergabestation 59 ist ein drehend angetriebener Übergabeförderer 61 vorgesehen, der Halteköpfe 62 aufweist. Die Halteköpfe 62 verfügen jeweils über mehrere Saughalter 63, 64, 65. Je nach Anzahl der gleichzeitig zu handhabenden Beutel 10 ist eine entsprechende Anzahl von Halteköpfen 62 nebeneinander vorgesehen.

Accordingly, several bags 10 are simultaneously removed in the region of a transfer station 16 from the periphery of the bag turret 58 and fed to a transport belt 60, stored there and transported away. The attachment of the tape 19 and the band 21 is carried out as described below:

• In the transfer station 59, a rotationally driven transfer conveyor 61 is provided, the holding heads 62 has. The holding heads 62 each have a plurality of suction holders 63, 64, 65. Depending on the number of simultaneously to be handled bag 10, a corresponding number of holding heads 62 is provided side by side.

With the help of a first suction holder 63, a tape 19 is removed from the circumference of a above the transfer conveyor 61 taped conveyor 66 and attached to the bag flap 16 of a bag 10 with a first portion 23 in the manner already described. In this case, the bag 10 are gripped by the suction holder 64, 65, namely as shown in FIG Fig. 24 , At the same time, at least one hook-shaped holding member 67 enters the revolver 58 and engages behind a bag 10 and presses it against the holding head 62 or its suction holder 64, 65 (FIG. Fig. 16 ).

In the next step, the second portion 25 of the tape 19 by means of a compressed air nozzle 68 partially wrapped around the imaginary bag edge between the front 17 and back 18.

The compressed-air nozzle 68 is arranged in the present embodiment on the holding head 62, namely on a support 69, on which the suction holders 63, 64, 65 are arranged.

The partial folding over of the second section 25 of the tape 19 takes place during the picking-up movement of the transfer conveyor 61, ie after the removal of the bags 10 from the bag turret 58 and before the transfer of the bags 10 to the transport belt 60 (FIG. Fig. 17 ).

In the next step, the second portion 25 of the tape 19 is completely folded over by means of a further compressed air nozzle 70 and attached to the bag 10.

The second compressed air nozzle 70 is not disposed on the transfer conveyor 61, but on a pivot mechanism, not shown, such that the compressed air nozzle 70 as in Fig. 18 and 19 shown moved along an elliptical path 71 and thereby pivoted about a bearing point. In this way, the compressed air nozzle 70 follows the path of movement of the bag 10 on the holding head 62, so that the second portion 25 of the tape 19 is gradually pressed along the contour of the bag 10 by means of compressed air and thus attached to the bag 10.

To transfer the bag 10, the holding members 67 are pivoted back and the bag 10 placed on the conveyor belt 60, the bags 10 with their longitudinal extent in the conveying direction facing the conveyor belt 60 are such that the bag flap 16 facing upward.

Fig. 24 shows, on the one hand, the position of the suction holders 63, 64, 65 on the bag 10. The suction holders 64 engage on both sides of the tape 19 in the area of the bag flap 16. The two suction holders 65 are positioned at a slightly greater distance from each other in the vicinity of an opposite imaginary bag edge. In an embodiment not shown can be dispensed with the suction holder 64. Further shows Fig. 24 by means of a marking 72 the approximate point of application of the compressed-air nozzles 68, 70.

It is understood that not necessarily two compressed-air nozzles 68, 70 must be used for folding over the second portions 25 of the tapes 19. It is also conceivable that this can be done only with the aid of a compressed air nozzle and / or with the aid of another organ.

During further transport of the bags 10 along the transport belt 60, a band 21 is attached to the bags 10 in the manner described above next. The laying of the bands 21 can be done as in the first embodiment by means of a laying drum.

First, a banderole 21 is placed on each bag 10 only with the first portion 23, while the bags 10 are guided between two side guides 73, 74 in the transport direction. In the conveying direction in each case front and back, the bag 10 between carriers 75 of the transport belt 60 are held.

Furthermore, the bags are 10 on the conveyor belt 60 that the bag 10 is exposed in the region of the bottom, for attachment of the second portion 25 of the bands 21. For this purpose, the conveyor belt 60 corresponding recesses 45 on.

After placing the banderoles 21, the bags 10 reach the working area of another transfer station 76, in which the second section 25 of the banderole 21 is folded over and attached in the manner already described.

In the area of the transfer station 76, the bags 10 are pressed from above by means of an upper guide 77 against the transport belt 60, wherein the bag flap 16 is fixed in its position. Further, a hold-down 78 is used, which is placed in the region of the banderole 21 on the bag flap 16, and a folding member 79 for folding and pressing the second portion 25 of the bandery 21st

The operation of the folding member 79 is comparable to the operation of the molding 52 in the first embodiment. By means of a nose 80, the second portion 25 of the band 21 is taken and moved down. Then, by pivoting the folding member 79, a curved contact surface 81 of the folding member 79 is placed against the contour of the bag 10 and the second portion 25 of the band 21 is pressed and attached.

Hold-down 78 and folding member 79 are respectively attached to the end of operating levers 82, which are coupled together and movable via a gear, not shown, in the manner shown. This results in a superimposed movement of hold-down 78 and folding member 79, such that while the hold-down 78 is placed on the bag 10, the second portion 25 of the sleeve 21 by the folding member 79 is first pressed down and then the contour of the bag 10 following against This is pressed into the region of the bottom of the bag 10th

• In Fig. 25 bis 29 ist ein drittes Ausführungsbeispiel gezeigt. Dabei kommt ein anderer Typ Beutel 10 zum Einsatz, nämlich ein sogenannter Seitenfaltbeutel. Dieser Typ Beutel 10 ist als solcher aus dem Stand der Technik bekannt. Hierzu wird auf die Anmeldungen DE 30 49 601 A1 und DE 32 14 240 A1 aus dem Hause der Anmelderin verwiesen.

Third embodiment:

• In Fig. 25 to 29 a third embodiment is shown. In this case, another type of bag 10 is used, namely a so-called side-folding bag. This type of bag 10 is known as such from the prior art. This will be on the registrations DE 30 49 601 A1 and DE 32 14 240 A1 from the applicant's home.

In the present embodiment, however, the bag 10 is provided with a longer bag flap 16 which, as in the first two embodiments, is attached to the bag flap 16 with a first portion 23 and projects beyond a rim 24 of the bag flap 16 with a second portion 25 and contour following the bag 10 and attached thereto.

Despite the slightly different from the first two embodiments construction of the bag 10 are for matching elements of the bag 10 and the device uses the same reference numerals. The following also describes only the aspects and features in which the third embodiment deviates from the two preceding embodiments.

Both the tape 19 and the band 21 are mounted starting from the front side 17 of the bag in the region of a bottom side 83 located between front side 17 and rear side 18. This is done according to Fig. 27 to 29 while the bag 10 lies flat on a conveyor belt 31 and the front 17 for attaching the first portions 23 of tape 19 and band 21 facing upward. However, in the present case, the transport belt 31 has no recess 57, since the blank does not have to be placed in the region of the underside of the bag 10.

Analogous to Fig. 6 to 8 the bag 10 abuts a slider 39 on one side. With a hold-down 41, the bag flap 16 is held in position. A blank is placed from above ( Fig. 27 ) and folded by means of a folding member 84 in the region of the substantially flat bottom side 83. This is done by gradually lowering the folding member 84 (FIG. Fig. 28 ).

Finally, the slider 39 is moved laterally in the direction of the folding member 84, so that the bag 10 or its bottom side 83 pressed against the folding member 84 and the blank on the bottom side 83 is attached over the entire surface ( Fig. 29 ). The folding member 84 takes over as far as part of the tasks of the guide 40 from the first two embodiments.

The dimensions of the folding member 84 are preferably selected so that the blanks in the region of the second portion 25 can rest against the folding member 84 essentially over the whole area.

It is conceivable that both the tape 19 and the band 21 are attached in one step by the same folding member 84 on the bottom side 83. It is also conceivable that, as in the first two embodiments, first in a first step, the tape 19 and then in a second step, the banderole 21 is attached to the bag 10.

Generally, it should be noted for all embodiments that the methods for attaching the tape 19 on the one hand and the band 21 on the other hand, of course, also can be exchanged. In principle, the use of the technique shown is also possible in connection with other types of packaging machines. In addition, of course, other separate blanks than tapes 19 or banderoles 21 are attached to the bags 10, possibly also in addition to a tape 19 and / or a band 21. <B> LIST OF REFERENCES: </ b> 10 bag 36 axis 11 bag 37 Umlegestation 12 Pocket front wall 38 bearing surface 13 Pocket rear wall 39 pusher 14 side seam 40 guide 15 side seam 41 Stripper plate 16 bag flap 42 pressing device 17 front 43 capstan 18 back 44 poor 19 Tape 45 recess 20 grip tab 46 pushrod 21 banderole 47 band magazine 22 Health Notes 48 application drum 23 first section 49 glue nozzle 24 edge 50 Umlegestation 25 second part 51 fitting 26 web 52 fitting 27 reel 53 guide 28 idler pulley 54 pushrod 29 cutter 55 frame 30 application drum 56 contact area 31 Conveyor belt 57 recess 32 guide 58 bag turret 33 takeaway 59 Transfer station 34 pressing device 60 Conveyor belt 35 foam roller 61 Transfer conveyor 62 holding head 63 Suction cup 64 Suction cup 65 Suction cup 66 Tape conveyor 67 holding member 68 compressed air nozzle 69 carrier 70 compressed air nozzle 71 train 72 mark 73 cornering 74 cornering 75 takeaway 76 Umlegestation 77 upper guide 78 Stripper plate 79 folding member 80 nose 81 contact area 82 actuating lever 83 bottom side 84 folding member
