Unter der Scheibe 16 befindet sich eine weitere, feststehende Scheibe, auf der die Schachteln 1 mit ihrem Boden aufliegen.The boxes 1 are inserted at the first station 17 into correspondingly dimensioned receptacles or holes 27 on the circumference of the disk 16. Under the disc 16 is another, fixed disc on which the boxes 1 rest with their bottom.

Der Antrieb der drehbaren Scheibe 16 ist so ausgebildet, daß die Schachteln 1 taktweise von einer zur nächsten Station 17 bis 24 transportiert werden.The drive of the rotatable disc 16 is designed so that the boxes 1 are cyclically transported from one to the next station 17 to 24.

Die Schachtelzufuhreinrichtung besteht aus einem Magazin 29, an dem die zusammengefalteten Schachteln bzw. Zuschnitte 1' der Faltschachteln hintereinander angeordnet sind. Die Zuschnitte 1' werden mittels eines (nicht dargestellten) verschwenkbar gelagerten Saugers, der die Zuschnitte 1' einzeln abnimmt, einer im einzelnen nicht näher dargestellten Schachtelauffalteinrichtung 30 zugeführt.The box feeder consists of a magazine 29 on which the folded boxes or blanks 1 'of the folding boxes are arranged one behind the other. The blanks 1 'are fed to a carton folding device 30 (not shown in detail) by means of a swivel-mounted suction device (not shown) which removes the blanks 1' individually.

Die Auffalteinrichtung 30 kann beispielsweise aus einem an einer Kante der Schachtel 1 angreifenden Hebel und einem an der diagonal gegenüberliegenden Kante der Schachtel 1 angreifenden Anschlag bestehen. Die aufgefalteten Schachteln 1 werden dann mit dem Sauger in Position über einer Aufnahme 27 der Scheibe 16 an der ersten Station 17 gebracht.The unfolding device 30 can consist, for example, of a lever engaging an edge of the box 1 and a stop engaging the diagonally opposite edge of the box 1. The unfolded boxes 1 are then brought into position by means of the suction device over a receptacle 27 of the disk 16 at the first station 17.

Ein von oben in die Schachtel 1 eingreifender (nicht dargestellter) Druckstempel drückt dann die Schachtel 1 in das Loch 27 und gleichzeitig die Bodenklappen gegeneinander. Falls ein sogenannter Patentboden vorgesehen ist, ist damit die Bildung des Bodens abgeschlossen. Wenn die Bodenklappen hingegen verklebt werden sollen, muß noch eine Klebstoffauftrageeinrichtung vor dem Eingriff des Stempels in die in der ersten Station 17 angeordnete Schachtel 1 wirksam werden.A pressure stamp (not shown) which engages into the box 1 from above then presses the box 1 into the hole 27 and at the same time the bottom flaps against one another. If a so-called patent floor is provided, the formation of the floor is thus completed. When the bottom flaps are to be bonded, however, still a need Klebstoffauftrageeinric tung h prior to engagement of the punch in the disposed in the first station 17 packet 1 are effective.

Zur Füllstation 19 werden die Pralinen 25 hintereinander von einem Transportband 31 befördert. Weiterhin sind an der Füllstation 19 soviele (nicht dargestellte) Sauger vorhanden, wie Pralinen 25 in eine Schachtel 1 gefüllt werden sollen, also z.B. zwei Sauger bei zwei in jede Schachtel 1 zu füllende Pralinen.The chocolates 25 are transported one after the other by a conveyor belt 31 to the filling station 19. Furthermore, there are as many suckers (not shown) at the filling station 19 as chocolates 25 are to be filled into a box 1, e.g. two suction cups for two chocolates to be filled in each box 1.

Die Sauger sind an einem (nicht dargestellten) Hebel angeordnet, der um eine senkrechte Achse verschwenkbar und auf und ab beweglich ausgebildet ist. Bei zwei Pralinen pro Schachtel wird der Hebel also über die beiden Pralinen 25 am Ende des Transportbandes 31 verschwenkt, so daß die beiden Sauger über den beiden Pralinen 25 angeordnet sind, wonach der Hebel nach unten geführt wird, die Sauger die Pralinen ansaugen, der Hebel nach oben geführt wird, über die Schachtel 1 in der Ausnehmung 27 der Scheibe16 an der Füllstation 19 verschwenkt wird, dann nach unten geführt wird, die beiden Sauger die beiden Pralinen 25 freigeben und schließlich der Hebel in seine Ausgangsposition mit den beiden Saugern über die nächsten beiden Pralinen 25 auf dem Transportband 31 zurückgeführt wird.The suction cups are arranged on a lever (not shown) which can be pivoted about a vertical axis and is movable up and down. With two chocolates per box, the lever is thus pivoted over the two chocolates 25 at the end of the conveyor belt 31, so that the two suckers are arranged over the two chocolates 25, after which the lever is guided downward, the suction cups suck the chocolates, the lever is guided upwards, is pivoted over the box 1 in the recess 27 of the disc 16 at the filling station 19, then is guided downwards, the two suction cups release the two chocolates 25 and finally the lever into its starting position with the two suction cups over the next two chocolates 25 is returned on the conveyor belt 31.

Mit ähnlich verschwenkbaren, auf und ab bewegbaren Saugern kann dann in der Station 20 bzw. 21 das kissenartige Füllstück bzw. der Garantieschein in die Schachtel 1 eingelegt werden.The pillow-like filling piece or the guarantee certificate can then be inserted into the box 1 in the stations 20 or 21 with suction cups which can be pivoted up and down in a similar manner.

Die Verschließeinrichtung an der Verschließstation 22 ist schematisch in Figur 2 und 2a wiedergegeben.The closing device at the closing station 22 is shown schematically in FIGS. 2 and 2a.

Sie weist zwei Niederdrücker 32 und 33 auf, die die Schließklappen 7 und 8 an den Stirnwänden 3 und 4 nach innen biegen. Die Schachtel 1 kann zur Erleichterung des Biegens der Schließklappen 7 und 8 je eine vorgeformte Faltlinie 34 aufweisen. Die Niederdrücker 32 und 33 weisen die Form eines sich im wesentlichen in Transportrichtung 35 der Scheibe 16 erstreckenden Teiles auf und sind jeweils am freien Ende eines Hebels 36 bzw. 37 befestigt. Die Hebel 36 und 37 sind um senkrecht verlaufende Achsen 38 und 39 verschwenkbar, die auf dem Maschinengestell 16 angeordnet sind. Die Hebel 36 und 37 werden derart angetrieben, daß die Niederdrücker 32 und 33 eine zangenförmige Bewegungen etwa in Transportrichtung 35 ausführen. Die Niederdrücker 32 und 33 werden als erstes an der Verschließstation 22 wirksam.It has two depressors 32 and 33 which bend the closing flaps 7 and 8 inwards on the end walls 3 and 4. The box 1 can each have a pre-formed fold line 34 to facilitate the bending of the closing flaps 7 and 8. The depressors 32 and 33 have the shape of a part extending essentially in the transport direction 35 of the disk 16 and are each fastened to the free end of a lever 36 and 37, respectively. The levers 36 and 37 can be pivoted about perpendicular axes 38 and 39 which are arranged on the machine frame 16. The levers 36 and 37 are driven in such a way that the depressors 32 and 33 execute a tong-shaped movement approximately in the transport direction 35. The depressors 32 and 33 are first effective at the closing station 22.

Alsdann werden-die Schließklappen 9 und 10 an den Seitenwänden 5 und 6 über die von den Niederdrückern 32 und 33 nach unten gedrückten Schließklappen 7 und 8 gebogen. Um die Seitenflächen, die die Schauseiten der Packung bilden, nicht durch Knicke zu verschandeln, weisen die Schließklappen 9 und 10 keine Knicklinien auf im Gegensatz zu den Knicklinien 34 der Schließklappen 7 und 8 an den Stirnwänden 3 und 4.Then the closing flaps 9 and 10 on the side walls 5 and 6 are bent over the closing flaps 7 and 8 pressed down by the depressors 32 and 33. In order not to spoil the side surfaces that form the end faces of the pack by kinks, the closing flaps 9 and 10 have no folding lines, in contrast to the folding lines 34 of the closing flaps 7 and 8 on the end walls 3 and 4.

Zum Biegen der Schließklappen 9 und 10 der Seitenwände 5 und 6 sind zwei Greifarme 40 und 41 vorgesehen, die als sich in Transportrichtung 35 der Fördereinrichtung erstreckende Teile ausgebildet sind. Die Greifarme 40 und 41 sind quer zur Transportrichtung 35 der Fördereinrichtung aufeinander zu beweglich. Dazu sind die beiden Greifarme 40 und 41 jeweils an einem Hebel 42 und 43 befestigt. Die beiden Hebel 42 und 43 sind an waagrecht verlaufenden Achsen 44 und 45 drehbar angelenkt.For bending the closing flaps 9 and 10 of the side walls 5 and 6, two gripping arms 40 and 41 are provided, which are designed as parts which extend in the transport direction 35 of the conveying device. The gripping arms 40 and 41 can be moved towards one another transversely to the transport direction 35 of the conveying device. For this purpose, the two gripping arms 40 and 41 are each fastened to a lever 42 and 43. The two levers 42 and 43 are pivoted on horizontally extending axes 44 and 45.

Der Antrieb jeder der beiden Greifarme 40 und 41 erfolgt durch einen drehfest an den drehbaren Achsen 44 und 45 angeordneten Hebel 46 und 47, der über je einen Mitnehmer 48 bzw. 49 mit dem Hebel 42 und 43 der Greifarme 40 und 41 verbunden ist.Each of the two gripping arms 40 and 41 is driven by a lever 46 and 47 arranged on the rotatable axes 44 and 45 in a manner fixed against relative rotation, which is connected to the levers 42 and 43 of the gripping arms 40 and 41 via a driver 48 and 49, respectively.

Jeder Mitnehmer 48 bzw. 49 besteht aus einem am Hebel 42 bzw. 43 der Greifarme 40 und 41 vorgesehenen Schlitz oder Langloch 50 bzw. 51 und einem Stift 52 bzw. 53, der an dem Hebel 46 bzw. 47 befestigt ist und in das zugehörige Langloch 50 bzw. 51 eingreift.Each driver 48 or 49 consists of a slot or slot 50 or 51 provided on the lever 42 or 43 of the gripping arms 40 and 41 and a pin 52 or 53 which is fastened to the lever 46 or 47 and into the associated one Elongated hole 50 or 51 engages.

Weiterhin ist jeder Hebel 42, 43 und 46, 47 zweiarmig ausgebildet, wobei der von der Schachtel 1 abgewandte Arm jedes Greiferhebels 42 bzw. 43 mit dem zugehörigen Arm des betreffenden Hebels 46 bzw. 47 über eine Zugfeder 54 bzw. 55 verbunden ist.Furthermore, each lever 42, 43 and 46, 47 is designed with two arms, the arm of each gripper lever 42 or 43 facing away from the box 1 being connected to the associated arm of the respective lever 46 or 47 via a tension spring 54 or 55.

Werden die Hebel 46 und 47 aufeinander zu verschwenkt (Fig. 2), nimmt also der Stift 52 bzw. 53 in dem Langloch 50 bzw. 51 den zugehörigen Greifarm 40 bzw. 41 mit, bis die beiden Greifarme 40 und 41 auf den einander gegenüber liegenden Seiten der Schachtel 1 im Bereich des oberen Randes der Verschlußklappen 9 und 10 der Seitenwände 5 und 6 aneinanderschlagen. Im weiteren Verlauf der Drehbewegung der Hebel 46 und 47 erfolgt eine Federbelastung der Greifarme 40 und 41 durch die Federn 54 und 55, wodurch die Enden der Schließklappen 9 und 10 der Seitenwände 5 und 6 zusammengehalten werden (Fig. 2a).If the levers 46 and 47 are pivoted towards one another (FIG. 2), the pin 52 or 53 takes the associated gripping arm 40 or 41 in the elongated hole 50 or 51 until the two gripping arms 40 and 41 face each other lay the sides of the box 1 together in the area of the upper edge of the flaps 9 and 10 of the side walls 5 and 6. In the further course of the rotary movement of the levers 46 and 47, the gripping arms 40 and 41 are loaded by the springs 54 and 55, as a result of which the ends of the closing flaps 9 and 10 of the side walls 5 and 6 are held together (FIG. 2a).

An den Hebeln 46 und 47 sind Laschenverriegelungsteile 56 und 57 vorgesehen. Die Laschenverriegelungsteile 56 und 57 sind hammerkopfförmig ausgebildet. Sie bestehen aus Kunststoff und weisen eine Abschrägung 58 auf, die von unten nach oben schräg zur betreffenden Lasche 11 bzw. 12 verläuft.Tab locking parts 56 and 57 are provided on the levers 46 and 47. The tab locking parts 56 and 57 are formed like a hammer head. They are made of plastic and have a bevel 58 which runs obliquely from bottom to top to the tab 11 or 12 in question.

Die Hebel 46 und 47 sind so an den Drehachsen 44 und 45 angeordnet, daß die Laschenverriegelungsteile 56 und 57 an den Abschnitten 11 " bzw. 12" der Laschen 11 und 12 angreifen, also an den Abschnitten, die sich seitlich neben den mit den Einschnitten 13 und 14 versehenen Abschnitten 11' bzw. 12' der Laschen 11 und 12 befinden.The levers 46 and 47 are arranged on the axes of rotation 44 and 45 in such a way that the tab locking parts 56 and 57 engage on the sections 11 "and 12" of the tabs 11 and 12, that is, on the sections which are laterally adjacent to those with the incisions 13 and 14 provided sections 11 'and 12' of the tabs 11 and 12.

Die Hebel 46 und 47 sind an den beiden Achsen 44 und 45 so angeordnet, daß sie die in der in Figur 2 dargestellte Ausgangsposition besitzen. Weiterhin sind die Hebel 46 und 47 von der in Figur 2 dargestellten Ausgangsposition um einen Winkel verschwenkbar, daß die Laschenverriegelungsteile 56 und 57 über den Spitzbogen, den die durch die Greifarme 40 und 41 gebogenen Schließklappen 9 und 10 der Seitenwände 5 und 6 bilden, hinweg von der Seite der einen Seitenwand 5 bzw. 6 zur Seite der gegenüber liegenden Seitenwand 6 bzw. 5 der Schachtel 1 bewegbar sind (Fig. 2a).The levers 46 and 47 are arranged on the two axes 44 and 45 so that they have the starting position shown in Figure 2. Furthermore, the levers 46 and 47 can be pivoted through an angle from the starting position shown in FIG. 2 such that the tab locking parts 56 and 57 over the pointed arch formed by the closing flaps 9 and 10 of the side walls 5 and 6 bent by the gripping arms 40 and 41 can be moved from the side of one side wall 5 or 6 to the side of the opposite side wall 6 or 5 of the box 1 (Fig. 2a).

Auf diese WeisL"biegen die Laschenverriegelungsteile 56 und 57 die Laschenabschnitte 11' und 12' der Laschen 11 und 12 um die, betreffende Knicklinie 15 etwa im rechten Winkel nach hinten und bewegt sie aneinander vorbei. Sobald sich die beiden Laschen abschitte 11'und 12"aneinander vorbeibewegt haben, schnappen sie in ihre im wesentlichen in Schachtellängs- bzw. Transportrichtung 35 verlaufende Ausgangsposition zurück, wodurch die Einschnitte 13 und 14 ineinandergreifen. Die Laschenverriegelungsteile 56 und 57 werden alsdann zurückbewegt und nehmen dabei die Greifarme 40 und 41 mit, wodurch die Schließklappen 9 und 10 an den Seitenwänden 5 und 6 freigegeben werden. Alsdann werden die Niederdrücker 32 und 33 durch Verschwenken der Hebel 36 und 37 um die Achsen 38 und 39 aus der Schachtel 1 herausgezogen.In this Weisl "the flap locking parts 56 and 57 bend the tab portions 11 'and 12' of the flaps 11 and 12 to which respective crease line 15 approximately at right angles to the back and moving them past each other. As soon as the two tabs abschitte 11 'and 12 "have moved past each other, snap back into their starting position, which runs essentially in the longitudinal or transport direction 35, whereby the incisions 13 and 14 interlock. The tab locking parts 56 and 57 are then moved back, taking the gripping arms 40 and 41 with them, whereby the closing flaps 9 and 10 on the side walls 5 and 6 are released. The depressors 32 and 33 are then pulled out of the box 1 by pivoting the levers 36 and 37 about the axes 38 and 39.

Zum Antrieb ist jede Achse 44 und 45 mit einem Zahnrad 59 bzw. 60 versehen. Die Zahnräder 59 und 60 kämmen ineinander.
