FIG. 2a shows an enlarged illustration of the one side wall 15 with the guides for the chains. At the point of connection with the foot 3, the associated connecting element 10 has a vertical bore 20 instead of the horizontal bore 13, via which the connecting element is firmly screwed to a part 21 of the foot 3.
On the inner lateral leg 9, a guide 22, best seen in FIG. 2b, is firmly screwed to the profile part by means of a spacer bolt 23. The guide 22 has a holder 24 made of a web-shaped central part 25 and two C-or a substantially rectangular cross-section. bracket-shaped sections 28, 29. The sections 28, 29 are aligned with their long sides essentially parallel to the side walls 15, 16. Their inner cross section is substantially equal to the outer cross section of chain guide rods 26, 27 to be received. The lateral free ends 28 ', 29' of the sections 28, 29 are bent inwards. The chain guide rods are inserted into the profiles of sections 28, 29. They are held in place by a central section which is essentially U-shaped and has a base section 30 and lateral legs which can be connected to the central part 25, the free ends 31, 32 of the side legs thus pointing outward in the manner shown in FIG. 2b are bent over that, together with the inwardly bent free ends 28 ', 29' of the sections 28, 29, they lock the chain guide rods 26, 27 in these sections. The chain guide rods have longitudinal slots in which the endless chain 33 is guided with its rollers 34. The chain has clips in a known manner for gripping a packaging material web 35 to be guided through the machine.

Die Arbeitsstationen weisen an ihren Rahmen an den Seiten auf sich horizontal erstreckenden Achsen gelagerte Laufräder 38, 39 auf. Die Arbeitsstationen sind mit diesen Laufrädern auf den schienenförmigen Leisten 36, 37 Schienen gelagert und können auf denselben in Längsrichtung des Rahmens in einem vorbestimmten Schienenabschnitt zur Anpassung an bestimmte Formate hin und her bewegt werden.As can best be seen from FIGS. 6a and 6b, FIGS Sections in which the work stations 4, 5, 6 are arranged are rail-like strips 36, 37 provided which are fixed with vertical bores of the connecting elements 10 guided screws associated with them. The workstations point to their Frames mounted on the sides on horizontally extending axes Impellers 38, 39 on. The workstations are with these Wheels mounted on the rail-shaped strips 36, 37 rails and can be on the same in the longitudinal direction of the frame a predetermined rail section to adapt to certain Formats are moved back and forth.

Wie am besten aus Figur 7 ersichtlich ist, ist eine durch die gesamte Maschine vom Eingang bis zum Ausgang geführte Transporteinrichtung in Form einer über einen Motor 41 angetriebenen Endloskette 42 vorgesehen. Diese ergreift auf der Eingangsseite der Maschine eine zu verformende Materialbahn 43 und führt diese durch die verschiedenen Arbeitsstationen 4, 5, 6 bis zur Ausgangsseite vorwärts. Auf der Eingansseite ist ein Druckmarkensensor 40 angeordnet, der auf der Materialbahn 43 angebrachte Druckmarken erfaßt und das Ausgangssignal einem Eingang einer Steuerung 44 zuführt. In dem hier beschriebenen Ausführungsbeispiel ist der Druckmarkensensor an der Eingangsseite zum Erfassen von Druckmarken auf der unteren Bahn einer Packung angeordnet. Alternativ ist der Druckmarkensensor im Bereich der Zuführung einer Oberbahn zum Abdecken der zu bildenden Packungen angeordnet.As best seen in Figure 7, one is through the entire Transport device guided machine from entrance to exit in the form of an endless chain driven by a motor 41 42 provided. This takes effect on the entry side of the Machine a material web 43 to be deformed and carries it out the various workstations 4, 5, 6 to the exit side forward. A print mark sensor 40 is arranged on the input side, the print marks attached to the material web 43 are detected and supplies the output signal to an input of a controller 44. The print mark sensor is in the exemplary embodiment described here on the input side for capturing print marks on the lower lane of a pack. Alternatively, the Print mark sensor in the area of the supply of a top web for covering arranged the packs to be formed.

Die Arbeitsstationen 4, 5, 6 sind jeweils mit Wegmeßeinrichtungen 45, 46, 47 versehen, die entweder die Absolutstellung der Stationen oder durch Inkrementenmessung die Relativstellung der Stationen erfassen. Die Ausgänge der Wegmeßeinrichtung sind mit jeweiligen Eingängen der Steuerung 44 verbunden. Ferner ist die Steuerung 44 eingangsseitig mit dem Ausgang einer Dateneingabeeinrichtung 48 verbunden, über die von außen Daten über die gewünschte Stellung der Arbeitsstationen eingebbar sind.The work stations 4, 5, 6 are each with displacement measuring devices 45, 46, 47 provided either the absolute position of the stations or the relative position of the stations by increment measurement to capture. The outputs of the path measuring device are with respective Inputs of the controller 44 connected. Furthermore, the control 44 on the input side with the output of a data input device 48 connected, via the outside data on the desired position the workstations can be entered.

Jede der Arbeitsstationen 4, 5, 6 ist über einen Spindelantrieb 49, 50, 51 kraftschlüssig mit einem jeweiligen Stellmotor 52, 53, 54 verbunden, der seinerseits mit seinem Steuereingang mit einem Ausgang der Steuerung 44 verbunden ist. Ferner ist der Steuereingang des Antriebsmotors 41 mit einem Ausgang der Steuerung 44 verbunden. Anstelle des Spindelantriebes können auch andere Linearantriebe Anwendung finden.Each of the work stations 4, 5, 6 is via a spindle drive 49, 50, 51 non-positively with a respective servomotor 52, 53, 54 connected, which in turn with its control input with a Output of the controller 44 is connected. Furthermore, the control input of the drive motor 41 is connected to an output of the controller 44. Instead of the spindle drive, other linear drives can also be used Find application.

    the control device (44) is connected with the printing mark sensor (40) and being arranged such that the control adjusts the positions of the stations (4, 5, 6) relative to each other in the direction parallel to the transport direction of the material webb by controlling the drive devices in response to deviations of the printing mark distances from predetermined values detected by said single printing mark sensor.
  2. The packaging machine according to claim 1,
    characterized in that
    each lateral frame part comprises rail-like portions (36, 37) within the range of the movable stations (4, 5, 6) and the corresponding stations comprise wheel pairs (38, 39), and that the stations (4, 5, 6) are movable the wheels resting on the rail-like portions.
  3. The packaging machine according to claim 1 or 2,
    characterized in that
    position measuring devices (45, 46, 47) are provided in the range of the stations (4, 5, 6) for determining the respective positions of the stations (4, 5, 6) relative to a reference position of the frame.
  4. The packaging machine according to one of claims 1 to 3,
    characterized in that
    each of the movable stations (4, 5, 6) is shiftable by a linear drive (49 to 54).
  5. The packaging machine according to one of claims 1 to 4,
    characterized in that
    the control device (44) adds up the detected printing mark distances and adjusts the stations (4, 5, 6) regarding their position in dependence on the respective ultimate deviation from a reference value.
  6. The packaging machine according to one of claims 1 to 5,
    characterized in that
    the drive for the material webb feeding is controllable as a function of the output of the printing mark sensor (4).
