  • Fig. 2 shows a section along the line 11-11 on an enlarged scale and
  • Fig. 3 is a section along the line 111-111 in Fig. 2 on an enlarged scale.

Die Verpackungsmaschine 1 weist einen Maschinenrahmen 2, eine von diesem getragene Formstation 3 und eine Versiegelungsstation 4 auf. Eine Unterfolie 5 wird von einer Vorratsrolle 6 abgezogen und taktweise jeweils zwischen den Arbeitstakten der Stationen 3 und 4 vorwärtsbewegt: In der Formstation 3 werden Behälter 7 geformt, die nach dem Befüllen der Versiegelungsstation 4 zugeführt werden. Von einer zweiten Vorratsrolle 8 wird eine Oberfolie 9 abgezogen und über eine Umlenkrolle 10 über die Behälter 7 geführt, von wo aus die Oberfolie in die Versiegelungsstation 4 zum Verschließen der Behälter geführt wird.The packaging machine 1 has a machine frame 2, a molding station 3 carried by the latter and a sealing station 4. A lower film 5 is pulled off a supply roll 6 and is moved forward in cycles between the work cycles of stations 3 and 4: Containers 7 are formed in the forming station 3 and are fed to the sealing station 4 after filling. An upper film 9 is drawn off from a second supply roll 8 and guided over a deflecting roller 10 over the containers 7, from where the upper film is guided into the sealing station 4 for closing the containers.

Auf dem Weg der Oberfolie von def Vorratsroiie 8 zu der Umlenkrolle 10, also vor dem Weg der Oberfolie in die Versiegelungsstation 4 hinein ist eine Druckeinrichtung 11 vorgesehen.A pressure device 11 is provided on the path of the upper film from the supply roll 8 to the deflection roller 10, that is to say before the upper film moves into the sealing station 4.

Die Druckeinrichtung umfaßt einen Rahmen 12, der mit dem Maschinenrahmen 2 verbunden ist. Der Rahmen 1 2trägt zwei in einem Abstand voneinander angeordnete, sich in einer Richtung senkrecht zu der durch die Druckeinrichtung hindurchzuführenden Oberfolie 9 erstreckende Führungsstangen 13, 14, auf denen ein parallel zu der Oberfolienbahn angeordneter Querbalken 15 verschiebbar angeordnet ist. Der Querbalken trägt auf seiner der Oberfolie zugewandten Seite eine Heizeinrichtung 16 mit daran befestigten Drucktypen 17, 18, 19. Die Drucktypen sind als Klischees ausgebildet und sind auf der der Oberfolie 9 zugewandten Seite und parallel zu der Oberfläche der Oberfolie ausgerichtet angeordnet und so mit der Heizeinrichtung 16 verbunden, daß sie auf eine vorbestimmte Temperatur von vorzugsweise zwischen etwa 130 und 150°C aufheizbar sind. Der seitliche Abstand der Drucktypen 17, 18, 19 ist in Abhängigkeit von der Größe und Anzahl der in eine Richtung quer zur Vorschubrichtung der Maschine nebeneinander angeordneten Packungen so gewählt, daß der Aufdruck für jede der Packungsreihen erfolgt. Wie aus Fig. 2 ersichtlich ist, haben die Drucktypen zueinander einen Abstand.The printing device comprises a frame 12 which is connected to the machine frame 2. The frame 1 2 carries two guide rods 13, 14 which are arranged at a distance from one another and extend in a direction perpendicular to the upper film 9 to be passed through the printing device and on which a cross bar 15 arranged parallel to the upper film web is slidably arranged. The crossbar carries on its side facing the upper film a heating device 16 with attached printing types 17, 18, 19. The printing types are designed as clichés and are arranged on the side facing the upper film 9 and aligned parallel to the surface of the upper film and thus with the Heating device 16 connected that they can be heated to a predetermined temperature of preferably between about 130 and 150 ° C. The lateral spacing of the printing types 17, 18, 19 is selected as a function of the size and number of packs arranged next to one another in a direction transverse to the feed direction of the machine in such a way that the printing takes place for each of the pack rows. As can be seen from FIG. 2, the printing types are at a distance from one another.

Ferner ist parallel zu der durch die Druckeinrichtung geführten Oberfolie 9 auf der den Drucktypen gegenüberliegenden Seite und parallel zur Oberfolie 9 eine Widerlagerplatte 20 vorgesehen, an die während des Druckens die Oberfolie durch das Einwirken der Drucktypen 17, 18, 19 angelegt wird.Furthermore, an abutment plate 20 is provided parallel to the upper film 9 guided through the printing device on the side opposite the printing types and parallel to the upper film 9, to which the upper film is applied during printing by the action of printing types 17, 18, 19.

Es ist ein Antrieb 21 in Form einer Kolben-Zylinder-Einrichtung vorgesehen. Der Zylinder derselben ist mit dem Rahmen 12 fest verbunden. Die Kolbenstange ist mit dem Querbalken 15 fest verbunden. Der Antrieb ist so ausgerichtet, daß er über den Querbalken 15 die Drucktypen in die in Fig. 2 gezeigte zurückgezogene Stellung bzw. in die Druckstellung, in der die Drucktypen die Oberfolie gegen das Widerlager 20 drücken, in Abhängigkeit von einer Steuerung hin- und herbewegt.A drive 21 in the form of a piston-cylinder device is provided. The cylinder of the same is firmly connected to the frame 12. The piston rod is fixed to the crossbar 15. The drive is aligned so that it moves the print types over the crossbar 15 into the retracted position shown in FIG. 2 or into the print position, in which the print types press the top film against the abutment 20, depending on a control .

In einem rechten Winkel zu den Führungsstangen 13, 14 und parallel zu der Ebene der Oberfolie 9 sind zwei weitere Führungsstangen 22, 23 angeordnet und seitlich von dem Rahmen 12 gehalten. Auf diesen ist ein hin- und herschiebbares Gehäuse 24 angeordnet. Das Gehäuse umfaßt einen Sockel 25. In dem Sockel sind zwei waagerechte Bohrungen vorgesehen, durch die die beiden Führungsstangen 22, 23 hindurchgehen, und deren Durchmesser so gewählt ist, daß der Sockel auf den Führungsstangen frei gleitet. Ferner weist der Sockel eine senkrechte Mittenbohrung mit Kugellagern 26, 27 an jedem Ende der Bohrung auf. Darüber hinaus sind die Enden der Kette 36, die parallel zur Richtung der Führungsstangen 22, 23 verläuft, fest mit dem Sockel 25 verbunden.At a right angle to the guide rods 13, 14 and parallel to the plane of the top film 9, two further guide rods 22, 23 are arranged and held laterally by the frame 12. A housing 24 which can be moved back and forth is arranged on these. The housing comprises a base 25. Two horizontal bores are provided in the base, through which the two guide rods 22, 23 pass, and the diameter of which is selected such that the base slides freely on the guide rods. Furthermore, the base has a vertical center bore with ball bearings 26, 27 at each end of the bore. In addition, the ends of the chain 36, which runs parallel to the direction of the guide rods 22, 23, are firmly connected to the base 25.

Auf der Oberseite weist der Sockel ein als Heizkammer 29 ausgebildetes Gehäuse auf, welches lediglich auf der den Drucktypen zugewandten Seite eine sich vertikal erstreckende Öffnung 30 aufweist.On the top, the base has a housing designed as a heating chamber 29, which has a vertically extending opening 30 only on the side facing the printing types.

Der Innenraum der Heizkammer 29 ist im wesentlichen zylindrisch ausgebildet und so groß, daß eine Farbrolle 31 gerade hineinpaßt. Die Farbrolle 31 ist auf einem Rollendorn 32 aufgebracht und besteht aus Schaumstoff, der mit Druckfarbe getränkt ist. Die Druckfarbe ist so ausgebildet, daß sie bei Umgebungstemperatur fest ist und nicht färbt. Bei einer Erwärmung auf eine Temperatur oberhalb der Umgebungstemperatur und vorzugsweise in der Grö- βenordnung von 130 bis 150°C erweicht der Farbstoff und wird bei Kontakt mit Drucktypen an diese abgegeben.The interior of the heating chamber 29 is essentially cylindrical and so large that a paint roller 31 just fits into it. The paint roller 31 is applied to a roller mandrel 32 and consists of foam which is impregnated with printing ink. The printing ink is designed so that it is solid at ambient temperature and does not color. When heated to a temperature above the ambient temperature and preferably in the order of 130 to 150 ° C., the dye softens and is released to it when it comes into contact with printing types.

Die Farbrolle ist durch einen mit dem Rollendorn 32 verbundenen Achsfortsatz 34 in die vertikale Bohrung des Sockels 25 eingestreckt und wird in den Kugelagern 26, 27 geführt. An dem der Rolle abgewandten Ende des Achsfortsatzes ist ein Kettenrad 35 vorgesehen, welches drehfest mit dem Achsfortsatz 34 verbunden ist.The paint roller is stretched through an axial extension 34 connected to the roller mandrel 32 into the vertical bore of the base 25 and is guided in the ball bearings 26, 27. At the end of the axle extension facing away from the roller, a chain wheel 35 is provided which is connected to the axle extension 34 in a rotationally fixed manner.

Die Heizkammer 29 wird über eine Regeleinrichtung auf eine voreingestellte Temperatur von vorzugsweise ca. 130 bis 150°C erwärmt.The heating chamber 29 is heated to a preset temperature of preferably approximately 130 to 150 ° C. via a control device.

Parallel zu den Führungsstangen 22, 23 ist eine Endlos-Antriebskette 36 vorgesehen. Diese ist über zwei an den gegenüberliegenden Seiten des Rahmens 12 vorgesehene Kettenräder 37, 38 geführt. Das Kettenrad 38 ist über einen Motor 39 antreibbar. Die Antriebskette ist so mit dem Sockel verbunden, daß bei Bewegung der Antriebskette das Gehäuse 24 und damit die Farbfolie 31 mitgenommen und zwischen den beiden Seitenwänden des Rahmens in Richtung des Pfeiles 40 hin- und herbewegt wird.An endless drive chain 36 is provided parallel to the guide rods 22, 23. This is guided over two chain wheels 37, 38 provided on the opposite sides of the frame 12. The sprocket 38 can be driven by a motor 39. The drive chain is connected to the base in such a way that when the drive chain moves, the housing 24 and thus the color film 31 are carried along and moved back and forth between the two side walls of the frame in the direction of arrow 40.

Ferner ist eine zweite Antriebskette 41 vorgesehen, die über vier sich parallel zu der Achse der Farbrolle 31 erstreckende Umlenkzahnräder 42 - 45 geführt ist. Die zweite Antriebskette ist so ausgerichtet, daß sie sich mit dem Zahnrad 35 in Eingriff befindet. Die zweite Antriebskette ist über einen Motor 46 antreibbar.Furthermore, a second drive chain 41 is provided, which is guided via four deflection gears 42 - 45 which extend parallel to the axis of the ink roller 31. The second drive chain is oriented to engage the gear 35. The second drive chain can be driven by a motor 46.

Im Betrieb wird zunächst die Oberfolie in der in Fig. 2 gezeigten Weise zwischen den Drucktypen und der Widerlagerplatte, die vorzugsweise aus einem Elastomer gebildet ist, hindurchgeführt.In operation, the top film is first passed in the manner shown in FIG. 2 between the printing types and the abutment plate, which is preferably formed from an elastomer.

Bei eingeschalteter Heizung wird über den Motor 46 und die Antriebskette 41 die Farbrolle fortlaufend gedreht, so daß ständig eine gleichmäßige Erwärmung erfolgt. Zum Einfärben der Drucktypen wird der Motor 46 abgeschaltet, und gleichzeitig wird der Motor 39 angeschaltet. Dadurch wird die Farbwalze an den Klischees entlanggefahren, wobei durch die jetzt als Zahnstange wirkende Antriebskette 41 die Farbrolle ständig gedreht wird. Die Farbrolle rollt über die Drucktypen bzw. Druckklischees und gibt die Druckfarbe an diese ab. Sobald die Farbrolle in der zweiten Endlage ist und somit die Drucktypen eingefärbt sind, wird der Motor 39 abgestellt, und der Motor 46 wird eingestellt. Gleichzeitig werden die Drucktypen über den Antrieb 21 in Richtung des Pfeiles 47 gegen die Oberfolie gepreßt, wodurch die Farbe auf die Oberfolie übertragen wird. Da die Oberfolie nicht erwärmt ist, ist die auf sie übertragene Farbe sofort wischfest. Anschließend erfolgt der nächste Takt.When the heating is switched on, the paint roller is rotated continuously via the motor 46 and the drive chain 41, so that there is constant uniform heating. To color the printing types, the motor 46 is switched off, and at the same time the motor 39 is switched on. As a result, the inking roller is moved along the clichés, the ink roller being constantly rotated by the drive chain 41, which now acts as a toothed rack. The ink roller rolls over the printing types or printing clichés and delivers the printing ink to them. As soon as the ink roller is in the second end position and the printing types are thus inked, the motor 39 is switched off and the motor 46 is stopped. At the same time, the printing types are pressed against the upper film via the drive 21 in the direction of arrow 47, as a result of which the color is transferred to the upper film. Since the top film is not heated, the color transferred to it is immediately smudge-proof. The next bar then follows.
