Description
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Zuschnitten aus Pappe oder pappähnlichen Materialien mit den Merkmalen des Hauptanspruchs sowie eine Vorrichtung zur Durchführung des Verfahrens nach Oberbegriff von Anspruch 4.The present invention relates to a method for the production of blanks from cardboard or cardboard-like materials with the features of the main claim and to an apparatus for carrying out the method according to the preamble of claim 4.
Derartiges Verfahren gehört im Umfang der durch die
Mit einem derartigen Verfahren ist es möglich, außer den bei Kartonzuschnitten üblichen längs und quer verlaufenden Bearbeitungslinien, z. B. Schnitt-, Rill-, Perforations-, Stanz- und Falzlinien auch Bearbeitungslinien am Kartonzuschnitt anzubringen, die weder ausschließlich in Längs- noch ausschließlich in Querrichtung verlaufen.With such a method, it is possible, in addition to the usual in carton blanks longitudinal and transverse processing lines, for. As cutting, creasing, perforation, punching and folding lines and processing lines to attach to the carton blank that run either exclusively in the longitudinal or exclusively in the transverse direction.
Mit der Längsrichtung des Werkstücks bzw. Kartonzuschnitts ist diejenige Richtung gemeint, welche durch die Bewegungsrichtung des Transferantriebs definiert ist, mit dessen Hilfe die Werkstücke, ausgehend vom Einzugsbereich in die Maschine, durch die einzelnen Bearbeitungsstufen gefördert werden.With the longitudinal direction of the workpiece or carton blank is meant that direction which is defined by the direction of movement of the transfer drive, with the aid of which the workpieces, starting from the catchment area in the machine, are conveyed through the individual processing stages.
Liegen die Längsrichtungen aller nacheinander zu durchlaufenden Bearbeitungsmodule auf einer einzigen durchgehenden geraden Linie, so spricht man von einer sogenannten Inline-Maschine (s. z.B. Katalog Klett).If the longitudinal directions of all processing modules to be traversed successively are on a single continuous straight line, this is referred to as a so-called inline machine (see, for example, Klett's catalog).
Zu den Bearbeitungsmodulen gehören neben Druckmodulen, Stanzmodulen, Perforationsmodulen usw. alle bei der Herstellung derartiger Kartonzuschnitte notwendigen einzelnen Baugruppen, innerhalb derer die Kartonzuschnitte jeweils einer besonderen Bearbeitungsart unterworfen sind.In addition to printing modules, punching modules, perforation modules, etc., the processing modules include all the individual assemblies required in the production of such carton blanks, within which the blanks are each subjected to a special type of processing.
Wie aus oben genannter
Diese Aufgabe löst die Erfindung mit den Merkmalen des Anspruchs 1.This object is achieved by the invention with the features of claim 1.
Eine hierfür geeignete Vorrichtung ergibt sich aus den Merkmalen des Anspruchs 4.A device suitable for this purpose results from the features of claim 4.
Die Erfindung beruht auf dem Grundgedanken, die Plottereinrichtung bzw. das Plottermodul so auszugestalten, dass das jeweilige Bearbeitungswerkzeug am Plottermodul ausschließlich in Querrichtung bewegbar ist, während die notwendige Längsrichtung der Bearbeitung nicht durch das Plottermodul selbst sondern durch eine entsprechend umgestaltete Transfereinrichtung zum Transport des Kartonzuschnitts durch die Bearbeitungsmaschine hindurch realisiert wird.The invention is based on the basic idea of designing the plotter module or the plotter module such that the respective machining tool can only be moved transversely on the plotter module, while the necessary longitudinal direction of the machining is not effected by the plotter module itself but by a correspondingly redesigned transfer device for transporting the cardboard blank the processing machine is realized through.
Die Transfereinrichtung wird zu diesem Zweck so ausgestaltet, dass sie, vorzugsweise über eine Ansteuerelektronik, sowohl vorwärts als auch rückwärts in Längsrichtung verfahrbar ist, möglichst mit variabler Geschwindigkeit.The transfer device is designed for this purpose so that, preferably via a control electronics, both forward and backward in the longitudinal direction is movable, if possible with variable speed.
Der dabei von dem Transferantrieb mitgenommene Kartonzuschnitt wird daher unter dem Bearbeitungskopf der Plottereinrichtung allein durch den Transferantrieb der Bearbeitungsmaschine bewegt, während der Bearbeitungskopf der Plottereinrichtung ausschließlich quer zur Längsrichtung beweglich ist.The carton blank taken along by the transfer drive is therefore moved under the processing head of the plotter device solely by the transfer drive of the processing machine, while the processing head of the plotter device is movable exclusively transversely to the longitudinal direction.
Somit müssen lediglich die Antriebsmotoren für die Querrichtung an der Plottereinrichtung und für die Längsrichtung am Transferantrieb miteinander so kombiniert werden, dass jede beliebige schräg verlaufende Bearbeitungsrichtung am Kartonzuschnitt ermöglicht wird. Dies geschieht über variable Geschwindigkeiten in Längs- bzw. Querrichtung.Thus, only the drive motors for the transverse direction on the plotting device and for the longitudinal direction on the transfer drive must be combined with each other so that any oblique machining direction is made possible on the carton blank. This is done via variable speeds in the longitudinal or transverse direction.
Mathematisch geschieht dies durch vektorielle Addition der jeweiligen Geschwindigkeiten in Längsrichtung und Querrichtung.Mathematically, this is done by vectorial addition of the respective velocities in the longitudinal and transverse directions.
Der Vorteil der Erfindung liegt insbesondere in der Ersparnis eines zusätzlichen Längsantriebs im Plottermodul, weil der Kartonzuschnitt ohnehin durch den Transferantrieb der Maschine in Längsrichtung durch den Plotter geführt wird.The advantage of the invention lies in particular in the savings of an additional longitudinal drive in the plotter module, because the carton blank is guided in any case by the transfer drive of the machine in the longitudinal direction through the plotter.
Dies hat die Erfindung erkannt und macht sich darauf basierend eine Steuerung zu Nutze, mit deren Hilfe die einzelnen steuerbaren Antriebsmotoren sowohl für die Längsrichtung als auch für die Querrichtung im Sinne der mathematischen Addition der jeweiligen Geschwindigkeitskomponenten addiert werden.This has recognized the invention and, based on this, makes use of a control system with the aid of which the individual controllable drive motors are added both for the longitudinal direction and for the transverse direction in the sense of the mathematical addition of the respective velocity components.
Es soll also ausdrücklich gesagt sein, dass die Plottereinrichtung lediglich eine Antriebsbewegung des Bearbeitungskopf in Querrichtung ermöglicht, während die Längsrichtung, in der sich das Werkstück bewegen muß, durch den Transferantrieb der Bearbeitungsmaschine realisiert wird.It should therefore be expressly stated that the plotting device only allows a drive movement of the processing head in the transverse direction, while the longitudinal direction, in which the workpiece must move, is realized by the transfer drive of the machine tool.
Auf diese Weise läßt sich die bislang übliche Baulänge derartiger Wellpapp-Verarbeitungsmaschinen erheblich reduzieren.In this way, the usual length of such corrugated cardboard processing machines can be significantly reduced.
Ohne den Grundgedanken der Erfindung zu verlassen, kann die Plottereinrichtung sogar bei in Querrichtung stillstehendem Bearbeitungskopf längs verlaufende Bearbeitungslinien erstellen bzw. bei in Längsrichtung stillstehenden Transferantrieb in Querrichtung verlaufende Bearbeitungslinien.Without departing from the basic idea of the invention, the plotting device can even create longitudinal machining lines in the case of a machining head that is stationary in the transverse direction, or machining lines running in the transverse direction in the longitudinal direction of the stationary transfer drive.
Man erhält auf diese Weise einen erheblich verminderten Bauaufwand, weil prinzipiell sogar die übliche Flachbettstanze bzw. Rotationsstanze fehlen kann.Obtained in this way a significantly reduced construction costs, because in principle even the usual flat bed punch or rotary die can be missing.
Die erfindungsgemäße Plottereinrichtung ist nämlich auch in der Lage, die zahlreichen durch Flachbettstanzen oder Rotationsstanzen erzeugten Bearbeitungslinien auszuführen.Namely, the plotting device according to the invention is also capable of executing the numerous processing lines produced by flat-bed punching or rotary blanking.
Der Kostenaufwand derartiger Gesamtmaschinen wird daher erheblich reduziert und die unternehmerseitig vorzuhaltenden Gebäudegrößen ebenfalls.The cost of such overall machines is therefore considerably reduced and the entrepreneur side vorzuhaltenden building sizes also.
Bevorzugt wird eine Weiterbildung, bei welcher der Transferantrieb der Werkstücke, beginnend hinter der Einzugsstation und vorzugsweise bis zu einer nachgeordneten Stapeleinrichtung ausschließlich auf einer einzigen geraden Linie liegt.Preference is given to a development in which the transfer drive of the workpieces, starting behind the feed station and preferably up to a downstream stacking device is exclusively on a single straight line.
Auf diese Weise kommt man zu einem Plottermodul, welches einfach zwischen bereits vorhandene Bearbeitungsmodule eingeschoben werden kann.In this way you get to a plotter module, which can be easily inserted between existing editing modules.
Um eine möglichst stufenfreie schräg verlaufende Bearbeitungslinie zu erzielen, wird ergänzend vorgeschlagen, daß das Bearbeitungswerkzeug der Plottereinrichtung während der Bearbeitung jedes einzelnen Werkstücks in jede beliebige Drehstellung drehbar ist, die sich aus der Vektoraddition der Geschwindigkeiten in Längs- und Querrichtung zu jedem Zeitpunkt der Bearbeitung ergibt.In order to achieve a stepless as possible oblique processing line, it is additionally proposed that the processing tool of the plotting device is rotatable during the processing of each individual workpiece in any rotational position, resulting from the vector addition of the velocities in the longitudinal and transverse directions at each time of processing.
Auf diese Weise liegt das Bearbeitungswerkzeug stets genau parallel zu der Bearbeitungslinie, die es herzustellen gilt, so dass bei entsprechend feiner digitaler Aufbereitung der Steuerdaten auch optisch kreisrunde Konturen ausgeschnitten oder ähnliches werden können. Dabei ist es auch möglich, statt einer einzigen Plottereinrichtung mehrere derartige Plottermodule inline vorzusehen, von denen beispielsweise ein erster Plottermodul Schnittlinien erzeugt, der nächste Plottermodul Perforationslinien, der dritte Plottermodul Rilllinien usw.In this way, the machining tool is always exactly parallel to the processing line that has to be produced, so that in accordance with fine digital processing of the control data and optically circular contours can be cut or the like. It is also possible to provide inline instead of a single plotter several such plotter modules, of which, for example, a first plotter module generates cut lines, the next plotter module perforation lines, the third plotter module creasing lines, etc.
Wesentlich ist für alle derartigen Plottermodule, dass die Bewegungskomponente des Bearbeitungskopfs nur in Querrichtung realisiert ist, während die Längsrichtung durch Bewegung des Werkstücks mittels der Transferantriebe erfolgt.It is essential for all such plotter modules that the movement component of the machining head is realized only in the transverse direction, while the longitudinal direction is effected by movement of the workpiece by means of the transfer drives.
Die Erfindung hat insoweit erkannt, dass es für die Bearbeitung derartiger Werkstücke allein auf die Relativbewegung zwischen Bearbeitungskopf und Werkstück ankommt und spart folglich an der Plottereinrichtung einen separaten Längsantrieb ein, welcher allerdings durch den entsprechend umgestalteten Transferantrieb ersetzt wird.The invention has recognized to the extent that it depends solely on the relative movement between the machining head and workpiece for the processing of such workpieces and thus saves on the plotter a separate longitudinal drive, which, however, is replaced by the correspondingly redesigned transfer drive.
Dabei kann es durchaus vorkommen, dass die Einzelbearbeitung jedes Werkstücks in dem Plottermodul mehr Zeit in Anspruch nimmt, als in den anderen Modulen.It may well happen that the individual processing of each workpiece in the plotter module takes more time than in the other modules.
Zu diesem Zweck wird vorgeschlagen, dass zumindest die Geschwindigkeiten der vorgelagerten Bearbeitungsmodule derart reduzierbar sind, dass für die Bearbeitung im Plottermodul hinreichend Zeit zur Verfügung steht.For this purpose, it is proposed that at least the speeds of the upstream processing modules can be reduced in such a way that sufficient time is available for processing in the plotter module.
Die Reduktion der Geschwindigkeiten kann bis zum Stillstand gehen.The reduction of the speeds can go to a standstill.
Ergänzend weist der Bearbeitungskopf am Plottermodul eine vertikale Drehachse auf, um welche er mittels separatem Antrieb in jede beliebige Drehstellung lagerbar ist.In addition, the processing head on the plotter module has a vertical axis of rotation about which it can be stored by means of a separate drive in any desired rotational position.
Die jeweils notwendige Drehstellung ergibt sich aus der vektoriellen Addition der Geschwindigkeiten in Längsrichtung und Querrichtung.The respectively required rotational position results from the vectorial addition of the speeds in the longitudinal direction and transverse direction.
Auf diese Weise steht das Bearbeitungswerkzeug stets genau parallel zur jeweiligen schräg verlaufenden Richtung, in welcher die Bearbeitungslinie an der Stelle der Bearbeitung weist.In this way, the machining tool is always exactly parallel to the respective oblique direction, in which the processing line points at the point of processing.
Zur Vermeidung eines unnötig großen Schlupfs wird darüber hinaus vorgeschlagen, den Transferantrieb im Plottermodul durch jeweils paarweise vorgesehenen Transportrollen zu realisieren, von denen jeweils ein Paar vor und ein Paar hinter dem Bearbeitungskopf des Plottermoduls sitzt, so dass sich das Werkstück zwischen den Transportrollen einklemmen läßt während es vorwärts bzw. rückwärts transferiert wird.To avoid an unnecessarily large slippage is also proposed to realize the transfer drive in the plotter module by pairs provided transport rollers, each of which a pair in front and a pair behind the processing head of the plotter module sits so that the workpiece can pinch between the transport rollers during it is transferred forward or backward.
Hierfür sind Ausführungsbeispiele angegeben.For this purpose, embodiments are given.
Im Folgenden wird die Erfindung anhand von Ausführungsbeispielen näher erläutert.In the following the invention will be explained in more detail by means of exemplary embodiments.

Sofern im Folgenden nichts anderes gesagt ist, gilt die folgende Beschreibung stets für alle Figuren.Unless otherwise stated below, the following description applies to all figures.
Die Figuren zeigen anschaulich das Verfahren zur Herstellung von Zuschnitten 1 aus Pappe oder pappähnlichen Materialien nach der vorliegenden Erfindung.The figures clearly show the process for producing blanks 1 of cardboard or cardboard-like materials according to the present invention.
Aus diesen Zuschnitten 1 werden üblicherweise Kartons gebildet, um vorbestimmte Waren zu verkaufen.From these blanks 1 usually cartons are formed to sell predetermined goods.
Ausgangsprodukt für das vorliegende Verfahren sind Werkstücke 2 von ursprünglich beliebiger Ausgangsform.Starting material for the present process are
Es handelt sich üblicherweise um Wellpapp- oder Pappzuschnitte von rechteckigem Grundriß. Diese Werkstücke werden durch längsverlaufende Bearbeitungslinien 3, querverlaufende Bearbeitungslinien 4 und darüber hinaus auch schrägverlaufende Bearbeitungslinien 5 zu Abwicklungen 50 des zu fertigenden Kartongebildes zugerichtet.These are usually corrugated cardboard or cardboard blanks of rectangular outline. These workpieces are trimmed by longitudinal processing lines 3, transverse processing lines 4 and beyond oblique processing lines 5 to
Bei den Bearbeitungslinien handelt es sich um Schnitte, Schlitze, Ritzen, Rillen, Perforationen oder auch um Falzlinien.The processing lines are cuts, slits, cracks, grooves, perforations or even fold lines.
Wie die untere Nebenfigur zeigt, können bei derartigen Zuschnitten 1 Bearbeitungslinien 5 auftreten, die weder ausschließlich in Längs- noch in Querrichtung verlaufen.As the lower secondary figure shows, 1 processing lines 5 can occur in such blanks, which extend neither exclusively in the longitudinal nor in the transverse direction.
Dabei ist die Längsrichtung definiert durch die sogenannte Transferantriebsrichtung 6, in welcher Richtung die Werkstücke 2 durch die einzelnen Bearbeitungsstufen 7a,7b,7c geführt werden.In this case, the longitudinal direction is defined by the so-called transfer drive direction 6, in which direction the
Im vorliegenden Fall handelt es sich um eine sogenannte Inline-Maschine, bei welcher alle Transferantriebsrichtungen der einzelnen Bearbeitungsstufen 7a-c auf einer einzigen geraden Linie liegen.In the present case, it is a so-called inline machine, in which all transfer drive directions of the
Wesentlich ist nun, dass diejenigen Bearbeitungslinien 5, die weder ausschließlich in Längs- noch ausschließlich in Querrichtung verlaufen, von einer Plottereinrichtung 8 erzeugt werden, welche parallel oberhalb und relativ zur Ebene des zu bearbeitenden Werkstücks beweglich einen Arbeitskopf 9 aufweist, welcher mit vorgegebenem Abstand zum Werkstück lediglich in Querrichtung zu jedem Punkt der jeweiligen Bearbeitungslinie verfahrbar ist, zur Bearbeitung an jedem Punkt des Werkstücks aktivierbar ist und dann im aktivierten Zustand entlang der jeweiligen schräg verlaufenden Bearbeitungslinie 5 mit gesteuertem Vorschub lediglich in Querrichtung 10 angetrieben ist, während das Werkstück gleichzeitig in Längsrichtung mittels des Transferantriebs 11 der Maschine bearbeitungsgerecht relativ zum Arbeitskopf 9 der Plottereinrichtung 8 positioniert wird.It is essential that those processing lines 5, which run neither exclusively longitudinally nor exclusively in the transverse direction, are produced by a
Es ist also wesentlich, dass der Bearbeitungskopf 9, der auch als Werkzeugträger dient, über eine geeignete elektromotorische Antriebsvorrichtung lediglich quer zum Werkstück verfahrbar ist, während das Werkstück durch die kombinierte Ansteuerung oben genannter motorischer Antriebseinrichtung und der Antriebseinrichtung für den Transferantrieb 11 bearbeitungsgerecht positioniert wird.It is therefore essential that the machining head 9, which also serves as a tool carrier, can only be moved transversely to the workpiece via a suitable electromotive drive device, while the workpiece is positioned for processing by the combined control of the above-mentioned motor drive device and the drive device for the
Die Längsrichtung 12 der Plotterbewegung wird daher durch entsprechende Ansteuerung des Transferantriebs 11 realisiert.The
Ergänzend weist der Bearbeitungskopf mit seinem Werkzeugträger einen Drehkopf 13 auf, so dass das Bearbeitungswerkzeug bzw. der Werkzeugträger der Plottereinrichtung 8 während der Bearbeitung des jeweiligen Werkstücks 2 in jede beliebige Drehstellung drehbar ist, die sich aus der vektoriellen Addition der Geschwindigkeiten in Längsrichtung 12 und Querrichtung 10 ergibt.In addition, the machining head with its tool carrier on a
Der Drehkopf 13 weist einen hierfür geeigneten Drehantrieb 14 auf, der genau so wie der Transferantrieb 11 und der Antrieb für die Querrichtung 10 von einer elektrischen Steuerung 15 mit Steuersignalen beaufschlagt wird, um an dieser Stelle der Bearbeitungsmaschine die gewollt schräg verlaufende Bearbeitungslinie anzubringen.The
Die elektrische Steuerung 15 für die Plottereinrichtung weist als Input die geometrischen Daten des fertigen Zuschnitts 1 auf, so dass über entsprechende Positionssensoren die jeweilige Positionierung des Werkstücks 2 erfolgen kann während zugleich die notwendigen Bewegungen in Schrägrichtung der jeweiligen Bearbeitungslinien durch zeitgleiche Ansteuerung der Motoren von Längs- und Querantrieb erfolgt.The
Im vorliegenden Fall sind die Bearbeitungsmodule 17a,b,c unmittelbar aufeinanderfolgend angeordnet.In the present case, the
Da naturgemäß die Plottereinrichtung, abhängig von dem Zeitaufwand der Bearbeitung, einen Rückstau in demjenigen Bereich der Maschine verursachen kann, der vor ihr von den Werkstücken durchlaufen wird, ist eine weitere elektronische Steuerung 16 vorgesehen, mit deren Hilfe zumindest die Geschwindigkeiten der vorgelagerten Bearbeitungsmodule hier nur 17a so verlangsamt werden können, dass das Plottermodul 19 die zum jeweiligen Bearbeiten des Werkstücks 2 notwendige Zeit erhält.Since, of course, the plotting device, depending on the time required for processing, can cause a backwater in that area of the machine, which is passed in front of her from the workpieces, a further
Wesentlich ist dabei die Kopplung der Antriebe für die Längs- und Querrichtung am Plottermodul derart, dass die Geschwindigkeit des einen motorischen Antriebs, z.B. für die Längsrichtung in Abhängigkeit von der Geschwindigkeit des anderen motorischen Antriebs gesteuert wird.What is essential here is the coupling of the drives for the longitudinal and transverse directions on the plotter module such that the speed of the one motor drive, e.g. is controlled for the longitudinal direction in dependence on the speed of the other motor drive.
Dies erfolgt zweckmäßiger Weise nach dem Master-Slave-Prinzip, wobei als Master sowohl der Antrieb für die Längsrichtung als auch der Antrieb für die Querrichtung dienen kann, während der komplementäre Antrieb die Slave-Funktion übernimmt und umgekehrt.This is expediently carried out according to the master-slave principle, with the master serving both the drive for the longitudinal direction and the drive for the transverse direction can, while the complementary drive takes over the slave function and vice versa.
Die Reduzierung der Transfergeschwindigkeiten vor dem Plottermodul 19 betrifft insbesondere alle Antriebseinheiten, die zwischen der Einzugsstation 18 und dem Eingang zum Plottermodul angeordnet sind.The reduction of the transfer speeds in front of the
Für die dem Plottermodul nachgeordneten Bearbeitungsmodule gilt dies nicht zwangsläufig, kann jedoch zum Erhalt vorbestimmter Bearbeitungstakte durchaus Sinn machen.This does not necessarily apply to the processing modules downstream of the plotter module, but can certainly make sense to obtain predetermined processing cycles.
Ergänzend zeigt die
Es ist also durchaus möglich, diese unterschiedlichen Bearbeitungsschritte in ein und derselben Plottereinrichtung 8 zu vollziehen.It is therefore entirely possible to carry out these different processing steps in one and the
Ebenso ist es möglich, für jeden einzelnen Typ von Bearbeitungsschritten jeweils eine separate Plottereinrichtung 8 vorzusehen.It is also possible to provide a

Hierzu dient ein am Drehkopf 13 angreifender Drehantrieb 14, welcher über die elektrische Steuerung 15 für das Plottermodul während der Bearbeitung des jeweiligen Werkstücks derart steuerbar ist, dass sich die jeweilige Drehstellung aus der vektoriellen Addition der Geschwindigkeiten in Längsrichtung und Querrichtung ergibt.Serves for this purpose is a

Diese Brücke ist aus statischen Gründen beidseitig starr mit dem Maschinengestell verbunden.For static reasons, this bridge is rigidly connected to the machine frame on both sides.

Jeweils ein Paar dieser Transportrollen 21a,b bzw. 22a,b sitzt jeweils vor bzw. hinter dem Bearbeitungskopf 9 der Plottereinrichtung 8 und spannt zwischen sich das Werkstück 2 so ein, dass es durch entsprechende Drehbeaufschlagung der Transportrollen 21a,b;22a,b in die entsprechende Vorwärts- bzw. Rückwärts gerichtete Transferrichtung angetrieben wird.In each case, a pair of these
Dies wird hier dadurch erreicht, dass die beiden unteren Transportrollen 21b,22b über einen gemeinsamen umlaufenden Antriebsriemen in derselben Drehrichtung angetrieben werden, während die beiden oberen Transportrollen 21a,22a über jeweils einen separaten Koppelriemen 24a,24b in derselben Wirkrichtung angetrieben sind. Der Antrieb erfolgt schlupflos, z. B. über Zahnriemen.This is achieved here by the fact that the two

Claims (8)
- A method for the manufacture of cuttings (1) of cardboard or cardboard-like materials for the purpose of selling goods, of which flat workpieces (2) of original arbitrary shape display by processing lines running longitudinally and where necessary also laterally like intersection lines, creasing lines, perforation lines, punch lines and fold lines for the execution (50) of a manufactured cardboard structure prepared and in addition other processing lines (5), which run neither solely in a longitudinal nor solely in a lateral direction, where the longitudinal line is defined through the transfer gear (6), whereby said workpieces (2) are transported in succession through the several machining phases (7a, b, c) of the production machine, in which the cuttings are each subjected to a machining method, and where the other processing lines (5) that neither run solely in a longitudinal nor solely in a lateral direction are generated from a movable plotter device (8) that is parallel and relative to the level of the workpieces (2) for machining, of which the working head (9) is powered with a specified separation distance in the workpiece (2) manoeuvrable solely in the lateral direction (10) at each point of this other processing line (5), able to be activated for processing at each point and is powered with controlled feeding in the lateral direction (10) in the activated state along the respective other processing line, and that the workpiece (2) is positioned at the same time in the longitudinal direction by means of the transfer gear (11) processing-compliant with the machine relative to the working head (9) of the plotter device (8) and that the transfer speed of the protruding processing phase is slowed in such a way that the plotter device (8) saves the necessary time in the processing of the workpiece (2).
- The method according to claim 1, characterised in that the transfer drive (11) of the workpieces (2) takes place through the machine on a single straight line.
- The method according to claim 1 or 2, characterised in that the processing implement (20) of the plotter device (8) is rotary during the processing of the relative workpieces (2) in each arbitrary rotational position that arises from the vectorial addition of the velocity in longitudinal and lateral directions at each point in the process.
- Equipment for the implementation of the procedure for one of the claims 1 to 3, with several processing modules (17a, b, c) arranged in succession, in processing direction of the workpieces (2), like cutting, creasing, perforation, punching and folding modules and with a transfer gear for the transport of the products between the feeder station (18) in the machine and the subsequent processing modules (17a, b, c), characterised in that at least a single plotter module (19) is provided, at which the workpiece (2) is controllable in the longitudinal line of the manufacturing procedure position-wise through the transfer gear (11) of the processing machine both forwards and backwards and likewise subject to the relative lateral (10) velocity one of these portable processing implements (20) lying in a longitudinal direction in this plotter module (19) at right angles to the longitudinal direction.
- Equipment for claim 4, characterised in that the processing modules (17a, b, c, 19) directly follow each other and that during the forward/backward actions at least the velocity of the mounted processing modules (17a) in terms of the time required on the plotter module is reducible.
- Equipment for one of claims 4 or 5, characterised in that the processing implement (20) on the plotter module (19) is rotatable by a vertical axis in each arbitrary rotational position and able to be controlled in such a way during the processing of the respective products that the respective rotational position arises from the vectorial addition of the velocity in the longitudinal and lateral directions.
- Equipment for one of the claims 4 to 6, characterised in that the transfer gear (11) in the plotter module is formed through each pair of coordinated transport rollers (21a, b; 22a,b) above and below the product, of which each one pair (21a,b) sits in front and one pair behind the processing head (9) of the plotter modules (19) and that all transport rollers (21a, b;22a, b) are each drivable at the same time and with the same effective direction on the workpiece (2).
- Equipment for one of the claims 4 to 7, characterised in that the processing implement (20) sits on a fixed cross bridge (25) linked to the machine frame and is manoeuvrable on this solely in a lateral direction (10).
