Description

Die Erfindung betrifft eine Längsschneide-und/oder Rillmaschine für bewegte Materialbahnen, insbesondere für Wellpappebahnen nach dem Oberbegriff des Patentanspruches 1.The invention relates to a longitudinal cutting and / or creasing machine for moving material webs, in particular for corrugated cardboard webs according to the preamble of claim 1.

Von Wellpappeanlagen sind für ein Format immer kleinere Aufträge bei kürerzen Laufzeiten, d.h. höheren Arbeitsgeschwindigkeiten, zu erfüllen. Für Längsschneide- und/oder Rillmaschinen, die einen Bestandteil einer solchen Wellpappenanlage bilden, werden demzufolge immer kürzere Umstellzeiten für die Werkzeuge gefordert. Längsschneide- und/oder Rillmaschinen nach der DE-A-2 250 125 erreichen mittlere Umstellzeiten von ca. 10 Sekunden bei Einfachanordnung. Für eine moderne Wellpappenanlage ist dies zu lang. Um kurze Umstellzeiten realisieren. zu können, geht man immer mehr dazu über, zwei Längsschneide- und/ oder Rillmaschinen hintereinander in einer sogenannten Tandem-Anordnung aufzustellen. Während eine Maschine in Betrieb ist, werden die Werkzeuge der anderen Maschine für den nächstfolgenden Auftrag positioniert.Corrugated cardboard plants are getting smaller and smaller orders with shorter terms, i.e. higher working speeds. For slitting and / or creasing machines, which form part of such a corrugated cardboard system, ever shorter changeover times for the tools are required. Slitting and / or creasing machines according to DE-A-2 250 125 achieve average changeover times of approx. 10 seconds with a simple arrangement. This is too long for a modern corrugated cardboard system. To realize short changeover times. To be able to, there is an increasing tendency to set up two longitudinal cutting and / or creasing machines in a so-called tandem arrangement. While one machine is in operation, the tools of the other machine are positioned for the next job.

Bei Formatwechsel werden Ober- und Unterwerkzeuge der in Betrieb befindlichen Maschine getrennt und gleichzeitig die positionierten Werkzeuge der zweiten Maschine eingerückt. Die erforderliche Umstellzeit von einer Maschine zur anderen beträgt hierbei ca. 1 Sekunde. Die Maschine nach der genannten DE-PS ist zum Einsatz für die Tandem-Anordnung zu teuer, da jedes Werkzeug eine eigene Antriebsspindel besitzt und jedem Werkzeugpaar ein eigener Antriebsmotor, ein eigener IST-Wert-Geber und Auswertelektronik zugeordnet ist.When changing the format, the upper and lower tools of the machine in operation are separated and at the same time the positioned tools of the second machine are engaged. The changeover time from one machine to another is approx. 1 second. The machine according to the aforementioned DE-PS is too expensive to use for the tandem arrangement, since each tool has its own drive spindle and each tool pair is assigned its own drive motor, its own actual value transmitter and evaluation electronics.

Es ist weiter eine Längsschneide- und/oder Rillmaschine nach der DE-A-2142117 bekannt. Zum Positionieren findet eine Greiferanordnung Verwendung. Die Werkzeugkörper werden durch einen Verstellschlitten zum Zwecke des Positionierens bewegt und der Greifer gibt den jeweils zu positionierenden Werkzeugkörper frei. Sind alle Werkzeugkörper abgesetzt, werden sie pneumatisch oder hydraulisch auf den Werkzeugwellen verspannt. Nachteilig ist, daß sowohl beim Verstellvorgang, als auch insbesondere beim Festsetzen der Werkzeugkörper, erhebliche Maßdifferenzen auftreten können, weil die Werkzeugkörper im Verhältnis zum Wellendurchmesser sehr kurz sind und daher bei der geringsten Verschmutzung zum Verkanten neigen. Eine weitere Längsschneide- und/oder Rillmaschine, die ebenfalls mit einer Greiferanordnung arbeitet ist aus FR-A-2 274 415 (entspricht DE-A-25 26 599) bekannt.A slitting and / or creasing machine according to DE-A-2142117 is also known. A gripper arrangement is used for positioning. The tool bodies are moved by an adjustment slide for the purpose of positioning and the gripper releases the tool body to be positioned in each case. Once all the tool bodies have been removed, they are clamped pneumatically or hydraulically onto the tool shafts. It is disadvantageous that considerable dimensional differences can occur both during the adjustment process and in particular when the tool bodies are fixed, because the tool bodies are very short in relation to the shaft diameter and therefore tend to tilt at the slightest contamination. Another slitting and / or creasing machine, which also works with a gripper arrangement, is known from FR-A-2 274 415 (corresponds to DE-A-25 26 599).

Der Erfindung liegt die Aufgabe zugrunde, die eingangs beschreibene, bekannte Maschine unter Beibehaltung der Trennung von Führungswellen und Antriebswellen so zu verbessern, daß der hohe Aufwand an Verstelleinheiten vermieden wird.The invention has for its object to improve the known machine described above while maintaining the separation of guide shafts and drive shafts so that the high expenditure on adjusting units is avoided.

Die Erfindung löst diese Aufgabe mit den Merkmalen des kennzeichnenden Teils des Patentanspruches 1.The invention solves this problem with the features of the characterizing part of patent claim 1.

Die Erfindung bietet den Vorteil, daß die Längsschneide- und/oder Rillmaschine preiswerter gebaut werden kann, weil nur ein Positionierantrieb notwendig ist. Für eine Maschine mit drei Werkzeugstationen sind je nach Ausführungsvariante nur je sechs oder nur je zwei Verstellspindeln und Verschiebekörper notwendig.The invention offers the advantage that the slitter and / or scoring machine can be built more cheaply because only one positioning drive is necessary. For a machine with three tool stations, depending on the design variant, only six or only two adjusting spindles and sliding bodies are required.

Außerdem ist keine Verschiebung der gesamten Maschine zur Bahnkantenkorrektur mehr notwendig. Schließlich ist es möglich, ohne Verbreiterung der Maschine zusätzliche Werkzeugkörper anzubringen, dabei eine minimale Durchbiegung der Querträger zur Führung für die Werkzeugpaare zu gewährleisten. Zusätzlich werden ein leichter Werkzeugwechsel, minimale Verstellzeit bei Formatwechsel und hohe Verstellgenauigkeit erreicht.In addition, there is no longer any need to move the entire web edge correction machine. Finally, it is possible to attach additional tool bodies without widening the machine, thereby ensuring a minimal deflection of the crossbeams for guiding the tool pairs. In addition, easy tool changes, minimal adjustment times when changing formats and high adjustment accuracy are achieved.

Weitere Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further refinements of the invention result from the subclaims.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. In der Zeichnung zeigen:

The invention is explained in more detail below with reference to an embodiment shown in the drawing. The drawing shows:
  • Figure 1 is a side view of the slitter and / or creasing machine.
  • Figure 2 is a vertical section through the guide for the tool body.
  • Fig. 3 is a vertical longitudinal section through the adjusting device for the tool body, and

In der nachfolgenden Beschreibung ist die bewegte Materialbahn eine Wellpappenbahn und diese wird in einer horizontalen Ebene durch die Längsschneide- und/oder Rillmaschine 1 bewegt.In the following description, the moving material web is a corrugated cardboard web and this is moved in a horizontal plane by the slitting and / or creasing machine 1.

Die Längsschneide- und/oder Rillmaschine 1 bzw. 1' besitzt einen Rahmen 2, der einen jochartigen Grundrahmenteil 3 und seitliche Ständerteile 4 und 5 aufweist.The longitudinal cutting and / or creasing machine 1 or 1 'has a frame 2, which has a yoke-like base frame part 3 and side stand parts 4 and 5.

Der Grundrahmenteil 3 ist über Fundamentschienen 6 ortsfest mit dem Fundament 7 verbunden.The base frame part 3 is fixedly connected to the foundation 7 by means of foundation rails 6.

Überhalb und unterhalb der strichpunktiert gezeichneten Wellpappenbahn 8 sind Werkzeige 9, 10 angeordnet. Ein oberes Werkzeug 9 und ein unteres Werkzeug 10 wirken als Werkzeugpaar zusammen.Tools 9, 10 are arranged above and below the dash-dot corrugated cardboard web 8. An upper tool 9 and a lower tool 10 work together as a pair of tools.

In der Längsschneide-und/oder Rillmaschine 1 sind in mehreren Ebenen, die senkrecht zur Laufrichtung der Wellpappenbahn 8 verlaufen, in Längsrichtung der Bahn gesehen hintereinander, unterschiedliche Werkzeuge, wie z.B. Schneidemesser oder Rillwerkzeuge, angeordnet. Vorzugsweise sind Schneidemesser mit nachfolgenden Rillwerkzeugen kombiniert, so daß eine durch die Maschine laufende Wellpappenbahn 8 längs geschnitten und entsprechend herzustellenden Kartonzuschnitten gerillt werden kann. In ein- und derselben Querebene sind gleiche Werkzeuge, z.B. Schneidmesser oder Rillwerkzeuge, in einer Werkzeugstation vorgesehen.In the longitudinal cutting and / or creasing machine 1, in several planes that run perpendicular to the direction of travel of the corrugated cardboard web 8, different tools, such as e.g. Cutting knife or creasing tools. Cutting knives are preferably combined with subsequent creasing tools so that a corrugated cardboard web 8 running through the machine can be cut lengthways and cardboard blanks to be produced can be grooved. The same tools, e.g. Cutting knives or creasing tools, provided in a tool station.

Die in Fig. 1 angedeuteten Werkzeuge oberhalb und unterhalb der Wellpappenbahn 8 sind Schneidmesser, wobei jeweils ein Schneidmesser oberhalb und unterhalb der Wellpappenbahn 8 zu einem Werkzeugpaar zusammengefaßt sind.The tools indicated in FIG. 1 above and below the corrugated cardboard web 8 are cutting knives, with one cutting knife above and below the corrugated cardboard web 8 being combined to form a pair of tools.

Jedes Schneidmesser 9 oberhalb und jedes Schneidmesser 10 unterhalb der Wellpappenbahn 8 ist in einem schlittenförmigen Werkzeugkörper 11 auswechselbar gelagert. Die Werkzeugkörper 11 der oberen Werkzeuge 9 sind mittels Kugelführungen 12 verschiebbar längs parallelen Führungsstangen 13, 14 geführt. Die Führungsstangen 13, 14 sind mittels Befestigungen 15 an einem biegesteifen Querträger 16 befestigt. Der Querträger 16, der von im Abstand voneinander angeordneten, parallelen und an den Enden über Stirnplatten miteinander verbundenen U-Schienen gebildet ist, verbindet starr die oberen Enden der Ständerteile 4 und 5.Each cutting knife 9 above and each cutting knife 10 below the corrugated cardboard web 8 is exchangeably mounted in a slide-shaped tool body 11. The tool bodies 11 of the upper tools 9 are guided so that they can be displaced along parallel guide rods 13, 14 by means of ball guides 12. The guide rods 13, 14 are fastened to a rigid cross member 16 by means of fastenings 15. The cross member 16, which is formed by spaced-apart, parallel U-rails connected at the ends by end plates, rigidly connects the upper ends of the stand parts 4 and 5.

Die Werkzeugkörper 11 der unteren Werkzeuge 10 sind ebenfalls mittels Kugelführungen 17 verschiebbar an parallelen, im Abstand angeordneten Führungsstangen 18, 19 geführt. Die Führungsstangen sind mittels Befestigungen 20 an einem Querträger 21 befestigt. Der biegesteife Querträger 21 wird von zwei parallelen, im Abstand voneinander angeordneten und an den Enden über Stirnplatten miteinander verbundenen U-Schienen gebildet. Der Querträger 21 ist in Pfeilrichtung I höhenverschiebbar mit den Ständerteilen 4, 5 verbunden.The tool body 11 of the lower tools 10 are also guided by means of ball guides 17 on parallel, spaced guide rods 18, 19. The guide rods are fastened to a cross member 21 by means of fastenings 20. The rigid crossmember 21 is formed by two parallel U-rails which are arranged at a distance from one another and are connected to one another at the ends by end plates. The cross member 21 is connected to the stand parts 4, 5 so as to be vertically displaceable in the direction of the arrow I.

Zur Höhenverstellung des Querträgers 21 sind mit diesem seitliche Hubspindeln 22, 23 verbunden, die über eine endlose Kette 23' gemeinsam von einem doppelseitig beaufschlagten Druckmittel-Zylinder mit durchgehender Kolbenstange, beispielsweise einem Pneumatik-Zylinder, angetrieben sind. Hierdurch können die Werkzeuge 9, 10 aus ihrer Wirkstellung durch Absenken des unteren Querträgers 21 und damit der von diesem getragenen Werkzeuge 10 in die Außerwirkstellung überführt werden, in der eine neue Positionierung der Werkzeuge möglich ist.To adjust the height of the cross member 21, lateral lifting spindles 22, 23 are connected to it, which are driven via an endless chain 23 'jointly by a pressure medium cylinder acted on on both sides with a continuous piston rod, for example a pneumatic cylinder. As a result, the tools 9, 10 can be transferred from their operative position by lowering the lower cross member 21 and thus the tools 10 carried by the latter into the inoperative position, in which a new positioning of the tools is possible.

Die einzelnen Werkzeuge 9, 10 oberhalb und unterhalb der Wellpappenbahn 8 sind jeweils durch Antriebswellen 25, 26 angetrieben, welche zentrisch durch die Werkzeuge 9, 10, z.B. Messer, verlaufen. Die Antriebswellen 25, 26 sind längsgenutet, über Paßfedern wird ihre Drehbewegung übertragen auf die Werkzeuge, die ihrerseits längs der sich drehenden Wellen 25, 26 verschiebbar sind.The individual tools 9, 10 above and below the corrugated cardboard web 8 are each driven by drive shafts 25, 26 which are centered by the tools 9, 10, e.g. Knife, run. The drive shafts 25, 26 are longitudinally grooved, their key movement is transmitted via feather keys to the tools, which in turn can be moved along the rotating shafts 25, 26.

Die Antriebswellen 25, 26 ragen über den Ständerteil 4 hinaus. Außerhalb des Ständerteils 5 sind die Antriebswellen 26, 25 über nicht dargestellte Kardanwellen und über Ketten 27 antriebsmäßig mit einer durchgehenden Welle 28 verbunden, die über eine Kupplung 29 vom nicht dargestellten Hauptantrieb der gesamten Wellpappenanlage angetrieben wird.The drive shafts 25, 26 protrude beyond the stand part 4. Outside the stand part 5, the drive shafts 26, 25 are connected via a cardan shaft (not shown) and chains 27 to a continuous shaft 28, which is driven by a coupling 29 from the main drive (not shown) of the entire corrugated cardboard system.

Die über den Ständerteil 4 hinausragenden Wellenteile 30 und die gleichfalls über diesen Ständerteil vorstehenden Führungsstangenteile 31 ermöglichen das Überführen der Werkzeugpaare in einen Parkraum 32.The shaft parts 30 protruding beyond the stand part 4 and the guide rod parts 31 also protruding beyond this stand part enable the tool pairs to be transferred into a parking space 32.

Zum Verstellen der Werkzeuge 9, 10 dienen Verschieberohre 33 und 34. Diese verlaufen zwischen den U-Schienen des oberen Querträgers 16 und des unteren Querträgers 21. Sie verlaufen dabei parallel zu den Führungsstangen 13, 14 bzw. 18, 19.Sliding tubes 33 and 34 are used to adjust the tools 9, 10. These run between the U-rails of the upper cross member 16 and the lower cross member 21. They run parallel to the guide rods 13, 14 and 18, 19, respectively.

Die Verschieberohre 33, 34 durchqueren Backenbremsen 35, die an den Werkzeugkörpern 11 ausgebildet sind. Jede Backenbremse 35 besitzt eine schwenkbare Backe 36 mit einem Bremsbelag 37. An der schwenkbaren Backe 36 befindet sich ein Backenarm 38, der an seinem freien Ende eine Rolle 39 trägt.The sliding tubes 33, 34 traverse shoe brakes 35, which are formed on the tool bodies 11. Each shoe brake 35 has a pivotable shoe 36 with a brake lining 37. On the pivotable shoe 36 there is a shoe arm 38 which carries a roller 39 at its free end.

Die Bremsbacken 36 werden über eine Federanordnung 40 in Klemmstellung überführt, in der dann die Werkzeugkörper 11 auf den zugehörigen Verschieberohren 33 bzw. 34 festgeklemmt sind.The brake shoes 36 are transferred into a clamping position by means of a spring arrangement 40, in which the tool bodies 11 are then clamped on the associated sliding tubes 33 and 34, respectively.

Zum Verstellen der Werkzeugkörper 11 und damit der Werkzeuge 9, 10 bei gelöster Backenbremse 35 dient eine Verschiebeeinrichtung, welche einen Verschiebekörper 41 umfaßt. Mit diesem Verschiebekörper 41 fest verbunden ist das eine Ende jedes Verschieberohres 33, 34.A displacement device, which comprises a displacement body 41, is used to adjust the tool body 11 and thus the tools 9, 10 when the shoe brake 35 is released. One end of each displacement tube 33, 34 is fixedly connected to this displacement body 41.

Mit dem Mutternflansch 42 des Verschiebekörpers 41 fest verbunden ist eine Spindelmutter 43. Diese wird von einer Verstellspindel 44 durchquert. Diese Verstellspindel ist mittels eines Lagers 45 im Ständerteil 5 bzw. im verstellbaren Querträger 21 gelagert. Die Verstellspindel 44 durchquert zentrisch jedes Verschieberohr 33, 34. Sein freies Ende ist über ein Lager 46 schiebbar im Verschieberohr 33 bzw. 34 gelagert. Die Verstellspindel 44 ist durch einen Positioniermotor 47 antriebbar. Die Verstellspindeln 44 sind über Zahnriemen 48 miteinander verbunden.A spindle nut 43 is fixedly connected to the nut flange 42 of the displacement body 41. An adjusting spindle 44 passes through this. This adjusting spindle is mounted by means of a bearing 45 in the stand part 5 or in the adjustable cross member 21. The adjusting spindle 44 passes centrally through each shift tube 33, 34. Its free end is slidably supported in the shift tube 33 or 34 via a bearing 46. The adjusting spindle 44 can be driven by a positioning motor 47. The adjusting spindles 44 are connected to one another via toothed belts 48.

Die Verschieberohre 33, 34 sind über Gleitlager 49 in den Backenbremsen 35 gelagert.The sliding tubes 33, 34 are mounted in the shoe brakes 35 via slide bearings 49.

Da alle Werkzeugkörper 11 auf die Verschieberohre 33, 34 geklemmt werden können, die Verstellung aller Verschieberohre 33, 34 über einen einzigen Positioniermotor 47 erfolgt, kann auch die Bahnkantenkorrektur, d.h. die positionsgerechte Einstellung der Werkzeuge zur jeweiligen seitlichen Kante der Wellpappenbahn, über den Positionierantrieb erfolgen, so daß die Maschine nicht mehr verschiebbar sein muß.Since all tool bodies 11 can be clamped onto the sliding tubes 33, 34, the adjustment of all sliding tubes 33, 34 takes place via a single positioning motor 47, the web edge correction, i.e. the correct positioning of the tools for the respective lateral edge of the corrugated cardboard web is carried out via the positioning drive, so that the machine no longer has to be displaceable.

Das Ein- und Ausfahren der Werkzeugpaare der einzelnen Werkzeugstationen, die jeweils von den Werkzeugpaaren einer Vertikalebene gebildet werden, erfolgt über Pneumatikzylinder 24. Jeder Werkzeugstation ist ein Zylinder 24 zugeordnet. Wie aus Fig. 4 ersichtlich, besitzt im vorliegenden Fall die Längsschneide- und/oder Rillmaschine 1 drei Werkzeugstationen a, b, c in Bahnrichtung gesehen hintereinander gelegen. Es sind somit auch drei Pneumatikzylinder 24 vorhanden. Die einzelnen Zylinder 24 sind auf einem gemeinsamen Schlitten 50 angeordnet, der über den Verstellmotor 51 über eine Verstellspindel 52 antreibbar ist. Das Aus- und Einfahren der Werkzeugpaare der einzelnen Werkzeugstationen kann bei dieser Anordnung getrennt erfolge. Die Einjustierung der Werkzeugstationen, die sogenannte Rilltiefeneinstellung, erfolgt für alle drei Stationen gemeinsam durch Verstellung des Schlittens 50 über den Verstellmotor 51.The tool pairs of the individual tool stations, which are each formed by the tool pairs of a vertical plane, are moved in and out via pneumatic cylinders 24. A cylinder 24 is assigned to each tool station. As can be seen from FIG. 4, in the present case the longitudinal cutting and / or creasing machine 1 has three tool stations a, b, c located one behind the other in the web direction. There are therefore also three pneumatic cylinders 24. The individual cylinders 24 are arranged on a common carriage 50 which can be driven via the adjusting motor 51 via an adjusting spindle 52. With this arrangement, the tool pairs of the individual tool stations can be extended and retracted separately. The adjustment of the tool stations, the so-called creasing depth adjustment, is carried out for all three stations together by adjusting the slide 50 via the adjusting motor 51.

Die Werkzeugkörper 11 jedes Werkzeuges 9, 10 sind über die Federanordnung 40 und die Backenbremsen 35 überlicherweise auf den Verschieberohren 34, 33 festgeklemmt. Die Klemmung der Werkzeugkörper 11 auf den Verschieberohren 33, 34 kann im Bereich des Parkraumes 32 gelöst werden. Der Parkbereich beginnt hinter einer Sperrklinke 53 (Fig. 3).The tool bodies 11 of each tool 9, 10 are usually clamped onto the sliding tubes 34, 33 via the spring arrangement 40 and the shoe brakes 35. The clamping of the tool body 11 on the sliding tubes 33, 34 can be released in the area of the parking space 32. The parking area begins behind a pawl 53 (Fig. 3).

Das Lösen der Klemmung der Werkzeugkörper 11 an den Verschieberohren 33, 34 erfolgt beim Abräumen der Werkzeugkörper 11 vor einer neuen Positionierung der Werkzeuge. Hierzu läuft die am Bremsbackenarm 38 angeordnete Rolle 39 auf eine sich über den Parkraum 32 längserstreckende Auflaufschiene 54 auf, die in einer im Querschnitt C-förmigen Halteschiene 55 höhenbeweglich gelagert ist. Die Bodenseite jeder Auflaufschiene 54 ist über Druckkissen 56 beaufschlagbar. Wird über Druckkissen 56 die Auflaufschiene 54 bis zur Begrenzung durch die Haltschienen bewegt, wird beim Auflaufen der Rollen 39 und der damit verbundenen beweglichen Bremsbacke die Backenbremse gelüftet, d.h. die Klemmung des Werkzeugkörpers 11 auf dem Verschieberohr 33 bzw. 34 gelöst. Bei gelüfteter Backenbremse 35 läßt sich jeder Werkzeugkörper 11 relativ leicht auf dem zugehörigen Verschieberohr 33 bzw. 34 verschieben. Somit können leicht zusätzliche Werkzeugkörper 11 auf die vorstehenden Wellenteile bzw. Führungsstangenteile aufgeschoben bzw. es können Werkzeugkörper getauscht werden.The loosening of the clamping of the tool body 11 on the sliding tubes 33, 34 takes place when the tool body 11 is cleared before a new positioning of the tools. For this purpose, the roller 39 arranged on the brake shoe arm 38 runs onto a run-up rail 54 which extends longitudinally over the parking space 32 and is mounted such that it can move in height in a holding rail 55 which is C-shaped in cross section. The bottom side of each ramp rail 54 can be acted upon by pressure pads 56. If the guide rail 54 is moved to the limit by the holding rails via pressure pads 56, the shoe brake is released when the rollers 39 and the movable brake shoe connected to it, i.e. the clamping of the tool body 11 on the sliding tube 33 or 34 is released. When the shoe brake 35 is released, each tool body 11 can be moved relatively easily on the associated sliding tube 33 or 34. Additional tool bodies 11 can thus easily be pushed onto the projecting shaft parts or guide rod parts or tool bodies can be exchanged.

Wie aus Fig. 1 ersichtlich, erstreckt sich der Parkraum 32 auch außerhalb des Rahmens 2 der Maschine 1. Dadurch kann die Maschinenbreite trotz vieler Werkzeuge 9, 10 klein gehalten werden. Die Gefahr der Durchbiegung der Querträger 16 bzw. 21 wird verringert und die Einstellgenauigkeit erhöht. Die Sperrklinke 53 ist schwenkbar gelagert. Sie ist über einen Druckmittel-Zylinder 57 durch die Kolbenstange 58 betätigbar. In Sperrstellung greift die Klinkennase 59 mit einem Sperrteil 60 des Werkzeugkörpers 11. Der Zylinder 57 arbeitet mit zwei unterschiedlichen Schließdrücken. Die Schließstellung der Klinke 53 wird über einen nicht dargestellten Endschalter kontrolliert.As can be seen from FIG. 1, the parking space 32 also extends outside the frame 2 of the machine 1. As a result, the machine width can be kept small despite many tools 9, 10. The risk of deflection of the cross beams 16 and 21 is reduced and the setting accuracy is increased. The pawl 53 is pivotally mounted. It can be actuated by the piston rod 58 via a pressure medium cylinder 57. In the locked position, the pawl nose 59 engages with a locking part 60 of the tool body 11. The cylinder 57 works with two different closing pressures. The closed position of the pawl 53 is controlled by a limit switch, not shown.

Ein Positioniervorgang der Werkzeuge 9, 10 erfolgt folgendermaßen:The tools 9, 10 are positioned as follows:

a) Abräumen:a) Clearing:

Die Werkzeuge 9, 10 befinden sich in ihren positionierten Stellungen. Die Werkzeuge jeden Werkzeugpaares sind in ihren Positionierstellungen, d.h. auseinandergefahren, wozu der untere Querträger 21 mit den Werkzeugkörpern 11 und den unteren Werkzeugen 10 nach unten abgesenkt ist.The tools 9, 10 are in their positioned positions. The tools of each pair of tools are in their positioning positions, i.e. moved apart, for which the lower cross member 21 with the tool bodies 11 and the lower tools 10 is lowered down.

Die Sperrklinke 53 ist geöffnet, d.h. die Sperrklinkennase 59 ist im Gegenuhrzeigersinn etwas hochgeschwenkt und läßt die Sperrteile 60 der Werkzeugkörper 11 frei durchtreten.The pawl 53 is open, i.e. the pawl nose 59 is pivoted slightly counterclockwise and allows the locking parts 60 of the tool body 11 to pass freely.

Es wird angenommen, daß der Verschiebekörper 41 zugleich mit dem 'Werkzeugkörper 11 des ersten Werkzeuges (z.B. Nullmesser) verbunden ist. Bei Einschalten des Positioniermotors 47 werden über die Verstellspindel 44, Verschiebekörper 41, Verschieberohre 33 bzw. 34, die geklemmten Werkzeugkörper 11 unter Beibehaltung .ihrer Stellungen zueinander in Richtung zum Parkraum 32 verschoben. Bein Einlauf in den Parkraum 32 wird die Backenbremse 35 beim Auflaufen der Rolle 39 auf die ausgefahrene Auflaufschiene 54 gelüftet und damit die Klemmverbindung zwischen Werkzeugkörper 11 und Verschieberohr 33 bzw. 34 gelöst. Die nach und nach ankommenden Werkzeugkörper 11 schieben die bereits entklemmten Werkzeugkörper 11 immer weiter in den Parkraum 32 hinein. Nachdem alle Werkzeugkörper 11 im Parkraum 32 abgestellt sind und der Verschiebekörper 41 seine NullMarke mit nicht dargestelltem Endschalter erreicht hat, ist der Abräumvorgang beendet. Ein anschliessender Positioniervorgang kann beginnen.It is believed that the sliding body 41 of the first tool (eg zero meter) is connected simultaneously with the 'tool body. 11 When the positioning motor 47 is switched on, the clamped tool bodies 11 are displaced in the direction of the parking space 32 via the adjusting spindle 44, displacement body 41, displacement tubes 33 and 34, while maintaining their positions relative to one another. When entering the parking space 32, the shoe brake 35 is released when the roller 39 runs onto the extended run-on rail 54 and the clamping connection between the tool body 11 and the displacement tube 33 or 34 is released. The tool bodies 11 arriving gradually push the tool bodies 11 which have already been unclamped further and further into the parking space 32. After all tool bodies 11 have been parked in the parking space 32 and the sliding body 41 has reached its zero mark with a limit switch (not shown), the clearing process is ended. A subsequent positioning process can begin.

b) Positionieren der Werkzeuge:b) Positioning the tools:

Die Verstellklinke 53 wird durch den Zylinder 57 in die Schließstellung (Fig. 3) überführt. Der Zylinder 57 arbeitet zunächst mit dem niedrigeren Druck. Die Auflaufschiene 54 ist eingefahren. Dadurch werden alle Werkzeugkörper 11 in ihrer dicht aneinanderliegenden Stellung im Parkraum auf dem Verschieberohr 33 bzw. 35 geklemmt. Der Positioniermotor 47 treibt die Verstellspindel 44 mit umgekehrter Drehrichtung an. Die Zählung eines nicht dargestellten Positionszählers beginnt bei Null, wenn der Verschiebekörper 41 einen nicht dargestellten, z.B. durch einen Endschalter vorgegebenen Schaltpunkt überfährt. Der Verschiebekörper 41 wird durch die Verstellspindel 44 in Richtung von dem Parkraum 32 weg bewegt. Der erste nachfolgende Werkzeugkörper 11 läuft gegen die Klinkennase 59 der Sperrklinke 53 und drückt diese bei dem niedrigeren Druck des Zylinders 57 etwas auf. Dadurch wird der nicht dargestellte Klinkenendschalter betätigt. Die Auflauf schiene 54 wird ausgefahren, wodurch die Werkzeugkörper 11 auf dem Verschieberohr 33 bzw. 34 entklemmt werden. Der Zylinder 57 für die Sperrklinke 53 wird auf einen höheren Druck geschaltet, wodurch der anliegende Werkzeugkörper 11 sicher in seine Null-Position zurückgedrückt wird. Diese Null-Position muß dem Schaltpunkt entsprechen, bei welchem der Positionszähler zu Zählen beginnt.The adjusting pawl 53 is transferred to the closed position (FIG. 3) by the cylinder 57. The cylinder 57 initially works with the lower pressure. The run-up rail 54 is retracted. As a result, all of the tool bodies 11 are clamped in their closely abutting position in the parking space on the sliding tube 33 or 35. The positioning motor 47 drives the adjusting spindle 44 in the opposite direction of rotation. The counting of a position counter, not shown, starts from zero when the displacement body 41 has a position counter, not shown, e.g. passed by a limit switch predetermined switching point. The displacement body 41 is moved in the direction away from the parking space 32 by the adjusting spindle 44. The first subsequent tool body 11 runs against the pawl nose 59 of the pawl 53 and presses it slightly at the lower pressure of the cylinder 57. As a result, the jack limit switch, not shown, is actuated. The casserole rail 54 is extended, whereby the tool body 11 on the sliding tube 33 and 34 are unclamped. The cylinder 57 for the pawl 53 is switched to a higher pressure, as a result of which the adjacent tool body 11 is reliably pushed back into its zero position. This zero position must correspond to the switching point at which the position counter begins to count.

Sobald das eingestellte Maß zwischen dem ersten Werkzeug und dem nachfolgenden Werkzeug erreicht ist, wird der Positionierantrieb gestoppt, die Auflaufschiene 54 fährt ein, die im Parkraum befindlichen Werkzeugkörper werden auf dem Verschieberohr 33 bzw. 34 festgeklemmt und die Sperrklinke 53 öffnet.As soon as the set dimension between the first tool and the subsequent tool is reached, the positioning drive is stopped, the run-up rail 54 moves in, the tool bodies located in the parking space are clamped on the sliding tube 33 or 34 and the pawl 53 opens.

Der Positionierantrieb startet zunächst mit verminderter Stellgeschwindigkeit. Sobald der Sperrteil 60 des nachfolgenden Werkzeugkörpers 11 die Sperrklinkennase 59 verlassen hat (Endschalterkontrolle), schließt die Sperrklinke 53 mit niedrigem Druck.The positioning drive starts with a reduced positioning speed. As soon as the locking part 60 of the subsequent tool body 11 has left the locking pawl nose 59 (limit switch control), the locking pawl 53 closes with low pressure.

Die Sperrklinke 53 wird vom nächstfolgenden Werkzeugkörper 11 aufgedrückt, Auflaufschiene 54 ausgefahren, die noch im Parkraum befindlichen Werkzeugkörper 11 werden entklemmt, Sperrklinkenzylinder 57 auf höheren Druck geschaltet, dadurch: der dritte Werkzeugkörper 11 in Null-Position gedrückt und der Positionierantrieb schaltet auf maximale Verstellgeschwindigkeit und stoppt wieder bei Erreichen des eingestellten Maßes zwischen zweitem und drittem Werkzeug. Danach wiederholt sich der beschriebene Vorgang so oft, bis alle Werkzeuge positioniert sind. Der letzte Positionierschritt besteht darin, alle im richtigen Abstand zueinander auf den Verschieberohren festgeklemmten Werkzeuge gemeinsam noch so viel weiter zu verschieben, daß das Null-Messer an der vorgewählten Bahnkante steht.The pawl 53 is pressed on by the next tool body 11, the run-up rail 54 is extended, the tool body 11 still in the parking space is unclamped, the pawl cylinder 57 is switched to higher pressure, as a result: the third tool body 11 is pressed into the zero position and the positioning drive switches to the maximum adjustment speed and stops again when the set dimension between the second and third tool is reached. Then the described process is repeated until all tools are positioned. The last positioning step is to move all the tools clamped on the sliding tubes at the correct distance from each other so much further that the zero knife is at the pre-selected web edge.

Anstatt für jede Werkzeugstation für jede Verstellspindel einen Verschiebekörper 41 vorzusehen, kann nur je ein gemeinsamer Verschiebekörper für alle oberen und alle unteren Hälften von mehreren Werkzeugstationen, im vorliegenden Fall z.B. drei, vorhanden sein. Dadurch können Verstellspindeln entfallen und der Verstellantrieb vereinfacht sich.Instead of providing a displacement body 41 for each adjusting spindle for each adjustment spindle, only one common displacement body can be used for all upper and all lower halves of several tool stations, in the present case e.g. three, be present. This eliminates the need for adjustment spindles and simplifies the adjustment drive.
