Description

Die Erfindung betrifft eine Längsschneide- oder Rillmaschine für eine bewegte Wellpappebahn, mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a slitter or scoring machine for a moving corrugated cardboard web, with the features of the preamble of claim 1.

Eine derartige Längsschneide- oder Rillmaschine ist aus der GB 21 39 135 A bekannt. Diese besitzt überhalb und unterhalb der horizontal durchlaufenden Warenbahn Führungsbetten, die quer zur Warenbahn und mit Abstand übereinander angeordnet sind. Jedes Führungsbett ist um eine mittige Trag- und Verstellspindel hin- und herschwenkbar angeordnet. In jedem Führungsbett sind beiderseits der Trag- und Verstellspindel Werkzeugkörper in Reihe quer zur Warenbahn angeordnet. Jeder Werkzeugkörper ist in dem Führungsbett geführt. Er kann bei eingerückter Kupplung mittels der Verstellspindel verstellt werden. Jeder Werkzeugkörper trägt ein einziges Werkzeug, das über eine durchgehende Antriebsspindel antreibbar ist. Sind bei gekipptem Führungsbett die zusammenwirkenden Werkzeugreihen in Arbeitsstellung, nehmen die in Warenbahnlaufrichtung dahinter angeordneten Werkzeugreihen die Ausgangsstellung ein. Die in Ausgangsstellung befindlichen Werkzeugpaare können für eine nachfolgende Bearbeitung der Warenbahn in neue Positionen eingestellt werden. Hierzu sind die zugehörigen Kupplungen mit der gemeinsamen Verstellspindel zu kuppeln. Die von unterschiedlichen Werkzeugkörpern getragenen Werkzeuge eines Führungsbettes sind dabei gleich ausgebildet. Es ist nicht vorgesehen, die in Ausgangsstellung befindlichen Werkzeuge in gleicher Position wie die in Arbeitsstellung befindlichen zu belassen, um sie als Ersatzwerkzeug benützen zu können. Es ist weiter nicht vorgesehen, unterschiedliche Werkzeuge bei einem Führungsbett zu verwenden. So können z. B. nicht unterschiedliche Rillprofile oder Messer- und Perforierwerkzeuge eingesetzt werden.Such a slitting or creasing machine is known from GB 21 39 135 A. This has guide beds above and below the horizontally continuous web, which are arranged transversely to the web and at a distance one above the other. Each guide bed can be swiveled back and forth around a central carrying and adjusting spindle. In each guide bed, tool bodies are arranged in rows across the web on both sides of the carrying and adjusting spindle. Each tool body is guided in the guide bed. It can be adjusted using the adjusting spindle when the clutch is engaged. Each tool body carries a single tool that can be driven by a continuous drive spindle. If the interacting tool rows are in the working position when the guide bed is tilted, the tool rows arranged behind in the direction of the web run in the starting position. The tool pairs in the initial position can be set to new positions for subsequent processing of the web. To do this, the associated couplings must be coupled to the common adjusting spindle. The tools of a guide bed carried by different tool bodies are of identical design. It is not intended that the tools in the starting position be in the same position as those in the working position left in order to use them as replacement tools. It is also not intended to use different tools in a guide bed. So z. B. not different creasing profiles or knife and perforating tools can be used.

Aus der DE-PS 24 36 717 sind weiter Maschinen zum Längsschneiden und Rillen einer Warenbahn bekannt. Diese sind in einer Anlage hintereinander angeordnet und können wechselweise eingesetzt werden. Jede Maschine besitzt mehrere Werkzeugpaare in Reihen quer zur Laufrichtung der Warenbahn, angeordnet in Form einer sogenannten Revolvereinheit. Die nicht in Arbeitsstellung befindlichen Werkzeuge können paarweise in neue Position voreingestellt werden. Auch bei dieser bekannten Maschine ist nicht vorgesehen, unterschiedliche Werkzeuge zu verwenden.From DE-PS 24 36 717 machines for slitting and creasing a web are also known. These are arranged one after the other in a system and can be used alternately. Each machine has several pairs of tools in rows across the direction of the web, arranged in the form of a so-called turret unit. The tools that are not in the working position can be preset in pairs in a new position. In this known machine, too, it is not intended to use different tools.

Aus der DE 36 00 516 C2 ist eine Längsschneidvorrichtung für Warenbahnen mit hintereinander angeordneten unterschiedlichen Schneidsystemen bekannt. Mit solchen Längsschneidmaschinen sollen unterschiedliche Bahnmaterialien mit unterschiedlichen Schneidsystemen, z.B. rotierenden Messerpaaren, Klingen, Quetschmessern und dgl. geschnitten werden. Ober- und unterhalb der zu schneidenden Bahn sind Werkzeugpaare angeordnet. Jedes obere Werkzeugpaar ist an einem schwenkbar gelagerten Doppelarm gelagert, der für sich mittels eines Schwenkantriebes hin- und herschwenbar ist. Jeder Doppelschwenkarm ist schiebbar und einstellbar gelagert. Der Wechsel der Schneidwerkzeuge zum Einsatz unterschiedlicher Schneidsysteme erfolgt bei Wechsel der Warenbahn und nicht im Durchlaufbetrieb. Diese bekannte Längsschneidmaschine sieht nicht vor, daß gleiche Werkzeuge in neuen Positionen oder in gleichen Positionen zum Schneiden bzw. Bearbeiten der durchlaufenden Warenbahn eingesetzt werden sollen. Da jedem einzelnen Doppelarm für die Werkzeugpaare ein mitverschiebbarer Schwenkantrieb zuzuordnen ist, ist der Aufwand beträchtlich.DE 36 00 516 C2 discloses a longitudinal cutting device for webs with different cutting systems arranged one behind the other. With such slitting machines, different web materials are to be cut with different cutting systems, for example rotating pairs of knives, blades, squeezing knives and the like. Tool pairs are arranged above and below the web to be cut. Each upper pair of tools is mounted on a swivel-mounted double arm, which can be swung back and forth by means of a swivel drive. Each double swivel arm is slidable and adjustable. The changing of the cutting tools for the use of different cutting systems takes place when changing the web and not in continuous operation. This known slitting machine does not provide that the same tools should be used in new positions or in the same positions for cutting or processing the continuous web of material. Since each individual double arm for the tool pairs can be assigned a swiveling swivel drive, the effort is considerable.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs beschriebene Längsschneide- oder Rillmaschine so zu verbessern, daß es möglich wird, bei geringstem Aufwand beschädigte oder abgenutzte Werkzeuge oder Werkzeuge mit anderen Profilen in im wesentlichen gleichen Arbeitspositionen wirken zu lassen, dabei aber den üblichen Durchlaufbetrieb, d. h. mit kontinuierlich durchlaufender Warenbahn, aufrechtzuerhalten.The invention has for its object to improve the slitting or creasing machine described at the outset so that it is possible to have damaged or worn tools or tools with other profiles in essentially the same working positions, but with the usual continuous operation, d. H. with a continuously running web of goods.

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

Nach der Erfindung kann schnell und ohne Unterbrechung der kontinuierlichen Bewegung der Warenbahn ein Ersatzwerkzeug in Arbeitsstellung gebracht werden. Auch ist es möglich, statt eines Ersatzwerkzeuges anders ausgebildete Werkzeuge in Arbeitsstellung zu bringen, die z. B. eine andere Profilform aufweisen. Die Maschine nach der Erfindung ist dabei so aufgebaut, daß der geringstmögliche Bauaufwand erforderlich wird. Somit ist sie preisgünstig herstellbar.According to the invention, a replacement tool can be brought into the working position quickly and without interrupting the continuous movement of the web. It is also possible, instead of a replacement tool, to bring differently designed tools into the working position. B. have a different profile shape. The machine according to the invention is constructed so that the lowest possible construction effort is required. It is therefore inexpensive to manufacture.

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

Fig. 2
a partial section along the line II-II in Fig. 1st

Die nachfolgend beschriebene Längsschneide- und/oder Rillmaschine 1 findet für eine Wellpappenbahn 2 Anwendung.The slitting and / or creasing machine 1 described below is used for a corrugated cardboard web 2.

Die Längsschneide- und/oder Rillmaschine 1 besitzt ein stationäres Maschinengestell 3, das nur teilweise in Figur 1 angedeutet ist. Dieses Maschinengestell 3 trägt ein Führungsbett 4 für Werkzeugkörper 5. Das Führungsbett 4 umfaßt paralelle Längsträger 6, die quer zur Längsachse der durchlaufenden Wellpappenbahn 2 angeordnet sind. Diese Längsträger 6 sind an ihren Enden fest mit Schildplatten 7 verbunden. Die Schildplatten 7 sind über Schwenkzapfen 8 mit dem Maschinengestell 3 verbunden. Die Längsträger 6 weisen an ihrer Unterseite parallele Führungsschienen 9 mit kreisförmigem Querschnitt auf.The longitudinal cutting and / or creasing machine 1 has a stationary machine frame 3, which is only partially indicated in FIG. 1. This machine frame 3 carries a guide bed 4 for tool body 5. The guide bed 4 comprises parallel longitudinal members 6, which are arranged transversely to the longitudinal axis of the continuous corrugated cardboard web 2. These longitudinal beams 6 are firmly connected to shield plates 7 at their ends. The shield plates 7 are connected to the machine frame 3 via pivot pins 8. The longitudinal beams 6 have parallel guide rails 9 with a circular cross section on their underside.

Die Werkzeugkörper 5 besitzen an ihrer Oberseite passende Aufnahmen 11 für die Führungsschienen 9. Die Werkzeugkörper 5 tragen mehrere, im Ausführungsbeispiel zwei, dargestellte Werkzeuge 12, 12'. Diese können Schneidwerkzeuge oder Rillwerkzeuge sein. Dabei kann bei Schneid- oder Rillwerkzeugen ein Werkzeug als Ersatz vorgesehen sein. Bei einem Rillwerkzeug ist es auch möglich, andere Rillprofile vorzusehen.The tool bodies 5 have matching receptacles 11 for the guide rails 9 on their upper side. The tool bodies 5 carry several tools 12, 12 ', which are shown in the exemplary embodiment. These can be cutting tools or creasing tools. A tool can be provided as a replacement for cutting or creasing tools. With a creasing tool, it is also possible to provide other creasing profiles.

Die Werkzeuge 12, 12' werden über paralelle Antriebswellen 13, 13' angetrieben, die die Werkzeuge 12, 12' drehfest aber längsverschiebbar aufnehmen. Hierfür besitzen die Antriebswellen 13, 13' Längsnuten 10, mit denen Keile 10' greifen.The tools 12, 12 'are driven by parallel drive shafts 13, 13' which hold the tools 12, 12 'in a rotationally fixed but longitudinally displaceable manner. For this purpose, the drive shafts 13, 13 'have longitudinal grooves 10 with which wedges 10' engage.

Es ist auch möglich, nur eines der Werkzeuge 12 oder 12' über eine Antriebswelle 13 oder 13' anzutreiben. Dann sind die Werkzeuge 12, 12' über miteinander kämmende, nicht dargestellte Zahnungen verbunden.It is also possible to drive only one of the tools 12 or 12 'via a drive shaft 13 or 13'. Then the tools 12, 12 'are connected by intermeshing teeth, not shown.

Quer zur Wellpappenbahn 2 sind die Werkzeuge 12, 12' hintereinander reihenweise angeordnet. Zur Einstellung der Werkzeuge 12, 12' auf ihre Sollstellung ist z.B. eine durchgehende Verstellspindel 14 vorhanden. Jeder Werkzeugkörper 5 weist an seiner Oberseite eine steuerbare Kupplung 15 auf. Solche Verstellantriebe sind in verschiedenen Bauformen bekannt. Der dargestellte Verstellantrieb ist nur beispielsweise angegeben.Transversely to the corrugated cardboard web 2, the tools 12, 12 'are arranged in rows one behind the other. A continuous adjusting spindle 14 is provided, for example, for setting the tools 12, 12 'to their desired position. Each tool body 5 has a controllable coupling 15 on its upper side. Such adjustment drives are known in various designs. The adjustment drive shown is only given as an example.

Damit die Werkzeuge 12, 12′ wechselweise in Arbeitsstellung überführbar sind, ist das Führungsbett 4 mit einer Stelleinrichtung 16 verbunden, welche andererseits mit dem stationären Maschinengestell 3 verbunden ist. Vorzugsweise ist eine solche Stelleinrichtung 16 als Spindelhubvorrichtung ausgebildet, die seitlich außerhalb der Mittelebene am Führungsbett 4 angreift. Dadurch ist es möglich, das Führungsbett 4 um den Drehzapfen 8 begrenzt zu verschwenken. Da die Werkzeuge 12, 12′ symmetrisch zur Mittelebene angeordnet sind, kann auf einfache Weise über die Stelleinrichtung 16 wechselweise das eine oder das andere der Werkzeuge 12, 12′ in Arbeitsstellung überführt werden, in der ein solches Werkzeug mit der Wellpappenbahn 2 zusammenwirkt. Wie üblich sind in Längsrichtung der Wellpappenbahn 2 mehrere Einheiten von Werkzeugen in nicht dargestellter Weise angeordnet, wobei mehrere Reihen von Schneidwerkzeugen und mehrere Reihen von Rillwerkzeugen vorhanden sind. Ein solcher Aufbau ist gleichfalls üblich und daher nicht gesondert dargestellt.So that the tools 12, 12 'can be alternately transferred into the working position, the guide bed 4 is connected to an actuating device 16, which on the other hand is connected to the stationary machine frame 3. Such an adjusting device 16 is preferably designed as a spindle lifting device which acts laterally on the guide bed 4 outside the central plane. This makes it possible to pivot the guide bed 4 to a limited extent about the pivot pin 8. Since the tools 12, 12 'are arranged symmetrically to the central plane, one or the other of the tools 12, 12' can be transferred to the working position in a simple manner via the adjusting device 16, in which such a tool interacts with the corrugated cardboard web 2. As usual, several units of tools are arranged in the longitudinal direction of the corrugated cardboard web 2 in a manner not shown, with several rows of cutting tools and several rows of creasing tools being present. Such a structure is also common and is therefore not shown separately.

Neben den überhalb der Wellpappenbahn 2 vorgesehenen Werkzeugen 12, 12′ sind, wie aus Fig. 1 ersichtlich, damit zusammenwirkende Werkzeuge 17, 17′ unterhalb der Wellpappenbahn 2 angeordnet. Führungsbett, Antriebswellenstell-Einrichtungen und dgl. entsprechen dabei dem Aufbau überhalb der Wellpappenbahn 2.In addition to the tools 12, 12 'provided above the corrugated cardboard web 2, as can be seen from FIG. 1, cooperating tools 17, 17' are arranged below the corrugated cardboard web 2. The guide bed, drive shaft adjusting devices and the like correspond to the structure above the corrugated cardboard web 2.

Wie aus Fig. 2 ersichtlich, können die Werkzeuge 12, 12′ nicht bloß in einer Ebene parallel zur Längsmittelebene der Wellpappenbahn 2 angeordnet sein, sondern auch in überlappender Anordnung. Hierfür sind die mit den Antriebswellen 13, 13′ drehfest aber verschiebbar verbundenen Werkzeugträger 18 nabenförmig ausgebildet. Die davon getragenen, ringförmigen Rillwerkzeuge 12, 12′ nehmen dann einen gewissen Versatz zueinander ein. Bei Wechsel der Werkzeuge muß dann eine entsprechende Nachstellung erfolgen. Die Rillwerkzeuge 12, 12′ stützen sich über Kugellager 9, 19′ auf dem Werkzeugkörper 5 ab, der im Querschnitt unterschiedliche Stärke aufweist.As can be seen from Fig. 2, the tools 12, 12 'can be arranged not only in a plane parallel to the longitudinal center plane of the corrugated cardboard web 2, but also in an overlapping arrangement. For this purpose, the tool carrier 18 are formed hub-shaped with the drive shafts 13, 13 'rotatably but slidably connected. The ring-shaped creasing tools 12, 12 'carried thereby then take up a certain offset from one another. When changing the tools, an appropriate readjustment must then be made. The creasing tools 12, 12 'are supported by ball bearings 9, 19' on the tool body 5, which has different thickness in cross section.

Es ist auch möglich, statt nur zwei Werkzeuge an einem Werkzeugkörper 5 auch mehrere vorzusehen, insbesondere dann, wenn ein revolverartiger Anbau der Werkzeuge am Werkzeugkörper erfolgt.Instead of only two tools on one tool body 5, it is also possible to provide a plurality of tools, in particular when the tools are turret-like mounted on the tool body.

Es ist auch möglich nur das untere Führungsbett für die Werkzeuge 17, 17′ oder das obere und das untere schwenkbar auszubilden.It is also possible to form only the lower guide bed for the tools 17, 17 'or the upper and lower pivotable.
