Eine Wellpappe-Bearbeitungs-Vorrichtung 1, insbesondere zum Schneiden und/oder Rillen einer Wellpappe-Bahn 2, weist ein stationäres Maschinen-Gestell 3 auf, das auf dem Boden 4 abgestützt ist. An dem Maschinen-Gestell 3 sind quer zu einer Wellpappe-Bahn 2 verlaufende Querträger 6 angeordnet. Die Querträger 6 sind als Werkzeugbetten ausgebildet. Sie sind jeweils paarweise übereinander, spiegelsymmetrisch zur Wellpappe-Bahn 2 angeordnet. Die Querträger 6 sind jeweils um eine Achse verschwenkbar im Maschinen-Gestell 3 gelagert. Für die Verschwenkung der Querträger 6 sind insbesondere als Spindel-Mutter-Antrieb ausgebildete Schwenkantriebe 7 vorgesehen.A corrugated cardboard processing device 1, in particular for cutting and / or corrugating a corrugated web 2, has a stationary machine frame 3 which is supported on the bottom 4. On the machine frame 3 transverse to a corrugated web 2 extending cross member 6 are arranged. The cross member 6 are formed as tool beds. They are each arranged in pairs one above the other, mirror-symmetrical to the corrugated web 2. The cross member 6 are each mounted pivotably about an axis in the machine frame 3. For the pivoting of the cross member 6 in particular designed as a spindle nut drive pivot drives 7 are provided.

An den jeweils der Wellpappe-Bahn 2 zugewandten Seiten der Querträger 6 sind Führungs-Schienen 8 angebracht. Die Führungs-Schienen 8 werden auch als Linearlager bezeichnet und bilden ein erstes Führungs-Element. Es sind an jedem Querträger 6 jeweils zwei Führungs-Schienen 8 vorgesehen. Auf den Führungs-Schienen 8 sind einander wiederum paarweise zugeordnete Werkzeugträger 9 quer zur Transportrichtung 5 verschiebbar gelagert. Die Werkzeugträger 9 umfassen jeweils einen Führungsbock 10. Am oberhalb der Wellpappe-Bahn 2 angeordneten Führungsbock 10 ist jeweils ein Werkzeug 11 um eine Werkzeug-Achse 12 drehbar gelagert. Die Werkzeug-Achse 12 ist insbesondere senkrecht zur Transport-Richtung 5 ausgerichtet. Entsprechend ist an dem unterhalb der Wellpappe-Bahn 2 angeordneten Führungsbock 10 jeweils ein Gegenwerkzeug 13 um eine Gegenwerkzeug-Achse 14 drehbar gelagert. Bei den Werkzeugen 11 und Gegenwerkzeugen 13 kann es sich um Rillwerkzeuge zum Erzeugen einer Längsrillung in Transportrichtung 5 in der Wellpappe-Bahn 2 oder um Messer, insbesondere um Kreismesser, zum Längsschneiden der Wellpappe-Bahn 2 handeln. Die Werkzeuge 11 und Gegenwerkzeuge 13 können über einen beispielsweise aus der EP 0 922 543 A2 bekannten Drehantrieb angetrieben sein. Außerdem können die Werkzeuge 11 oder die Gegenwerkzeuge 13 jeweils auch als Gegen-Haltetisch 15 ausgebildet sein.At each of the corrugated web 2 facing sides of the cross member 6 guide rails 8 are attached. The guide rails 8 are also referred to as linear bearings and form a first guide element. There are two guide rails 8 are provided on each cross member 6. On the guide rails 8, in turn, mutually associated tool carriers 9 are displaceably mounted transversely to the transport direction 5. The tool carriers 9 each comprise a guide block 10. The guide block 10, which is arranged above the corrugated web 2, in each case rotatably supports a tool 11 about a tool axis 12. The tool axis 12 is aligned in particular perpendicular to the transport direction 5. Accordingly, a counter-tool 13 is rotatably mounted about a counter-tool axis 14 at the arranged below the corrugated web 2 guide block 10 each. The tools 11 and counter tools 13 can be scoring tools for producing a longitudinal grooving in the transport direction 5 in the corrugated web 2 or knives, in particular circular knives, for longitudinal cutting of the corrugated web 2. The tools 11 and counter tools 13 can, for example, from the EP 0 922 543 A2 be driven known rotary drive. In addition, the tools 11 or the counter tools 13 may each also be designed as a counter-holding table 15.

Die Werkzeuge 11 und Gegenwerkzeuge 13 sind jeweils mittels des Schwenkantriebs 7 in eine in Fig. 2 dargestellte Eingriffs-Position verschwenkbar, in welcher sie mit der Wellpappe-Bahn in Eingriff stehen. Entsprechend sind die Werkzeuge 11 und Gegenwerkzeuge 13 mittels der Schwenkantriebe 7 in eine in Fig. 1 dargestellte Park-Position verschwenkbar, in welcher sie nicht mit der Wellpappe-Bahn 2 in Eingriff stehen. Die Wellpappe-Bahn 2 ist somit berührungsfrei zwischen den Werkzeugen 11 und den Gegenwerkzeugen 13 hindurchgeführt, sofern sich diese in der Park-Position befinden.The tools 11 and counter tools 13 are each by means of the pivot drive 7 in an in Fig. 2 shown engaged position in which they are engaged with the corrugated web. Accordingly, the tools 11 and counter tools 13 by means of the pivot drives 7 in an in Fig. 1 Park position shown pivoted in which they are not engaged with the corrugated web 2. The corrugated web 2 is thus passed without contact between the tools 11 and the counter tools 13, provided that they are in the park position.

Die Werkzeugträger 9 sind jeweils am Querträger 6 in Richtung der Werkzeug-Achse 12, das heißt quer zur Transportrichtung 5 verschiebbar. Zur Verschiebung der Werkzeugträger 9 quer zur Transportrichtung 5 ist eine als Gewinde-Spindel 16 ausgebildete Stellwelle, welche drehbar im Maschinen-Gestell 3 gelagert ist, vorgesehen. Die Gewinde-Spindel 16 bildet ein zweites Führungs-Element. Zum Antrieb der Gewinde-Spindeln 16 ist jeweils ein über einen Zahnriemen 17 mit diesem verbundener Positioniermotor 18 vorgesehen. Jeder Werkzeugträger 9 weist eine auf der Gewinde-Spindel 16 angeordnete Spindelmutter 19 auf mit einem InnenGewinde 20, welches in ein dazu passendes Außen-Gewinde 21 der Gewinde-Spindel 16 eingreift. Die Spindelmutter 19 bildet ebenso wie die Lager des Werkzeugträgers 9 auf den Führungs-Schienen 8 ein Werkzeugträger-Lager.The tool carriers 9 are each on the cross member 6 in the direction of the tool axis 12, that is transversely to the transport direction 5 slidably. For displacement of the tool carrier 9 transversely to the transport direction 5 is designed as a threaded spindle 16 actuating shaft, which is rotatably mounted in the machine frame 3, is provided. The threaded spindle 16 forms a second guide element. To drive the threaded spindles 16, a positioning motor 18 connected thereto via a toothed belt 17 is provided in each case. Each tool carrier 9 has a threaded spindle 16 arranged on the spindle nut 19 with an internal thread 20 which engages in a mating outer thread 21 of the threaded spindle 16. The spindle nut 19 forms as well as the bearings of the tool carrier 9 on the guide rails 8 a tool carrier bearing.

Vorteilhafterweise ist an jedem Werkzeugträger 9 eine in den Figuren nicht dargestellte Kupplung vorgesehen, mittels derer die freie Drehbarkeit der Spindelmutter 19 gegenüber dem Werkzeugträger 9 unterbunden werden kann, mittels derer also die Spindelmutter 19 drehfest mit dem jeweiligen Werkzeugträger 9 verbunden werden kann.Advantageously, a coupling not shown in the figures is provided on each tool carrier 9, by means of which the free rotation of the spindle nut 19 relative to the tool carrier 9 can be prevented by means of which thus the spindle nut 19 rotatably connected to the respective tool carrier 9.

Außerdem umfasst die Wellpappe-Bearbeitungs-Vorrichtung 1 eine Schmier-Einrichtung 22 zur Schmierung der Lager zwischen den Werkzeugträgern 9 und den Führungselementen 8, 16.

Der Schmierstoff-Verteiler 23 weist eine Pumpe 25 und eine Vielzahl von Schmierstoff-Leitungen 26 auf. Außerdem ist eine Steuer-Einheit 27 zur Steuerung der Schmier-Einrichtung 22 vorgesehen, mittels welcher die Schmierung der Lager automatisiert durchführbar ist. Die Steuer-Einheit 27 ist vorzugsweise programmierbar. Die Schmierstoff-Leitungen 26 sind jeweils mittels eines steuerbaren Ventils 28 über die Pumpe 25 mit dem Schmierstoff-Behälter 24 verbunden.In addition, the corrugated cardboard processing apparatus 1 comprises a lubricating device 22 for lubricating the bearings between the tool carriers 9 and the guide elements 8, 16. The lubricating device 22 comprises a lubricant distributor 23 with at least one lubricant container 24. The lubricant Distributor 23 has a pump 25 and a plurality of lubricant lines 26. In addition, a control unit 27 is provided for controlling the lubricating device 22, by means of which the lubrication of the bearings can be carried out automatically is. The control unit 27 is preferably programmable. The lubricant lines 26 are each connected by means of a controllable valve 28 via the pump 25 to the lubricant reservoir 24.

Zur Zuführung des Schmierstoffs zu den zu schmierenden Lagern sind sowohl die Gewinde-Spindel 16 als auch die Führungs-Schienen 8 jeweils als Hohlwelle bzw. Hohlprofil mit einer Längs-Bohrung ausgebildet. Die Hohlwellen sind endseitig abgedichtet. Die Hohlwellen bzw. Hohlprofile können einen beliebigen Außenquerschnitt, insbesondere einen rechteckigen oder runden Querschnitt, besitzen. Zur Einleitung von Schmierstoff in die Hohlwellen ist jeweils eine Drehdurchführung 29 in mindestens einem am Maschinen-Gestell 3 angeordneten Wellen-Lager 30 vorgesehen. Über die Drehdurchführung 29 sind die Hohlwellen jeweils mit einer der Schmierstoff-Leitungen 26 des Schmierstoffs-Verteilers 23 verbunden. Hierbei ist jeweils einer der Gewinde-Spindeln 16 eine separate Schmierstoff-Leitung 26 zugeordnet. Ebenso ist jeder der Führungs-Schienen 8 jeweils eine separate Schmierstoff-Leitung 26 zugeordnet. Mittels der von der Steuer-Einheit 27 steuerbaren Ventile 28 sind somit die Hohlwellen einzeln, steuerbar mit Schmierstoff beaufschlagbar.For supplying the lubricant to the bearings to be lubricated, both the threaded spindle 16 and the guide rails 8 are each formed as a hollow shaft or hollow profile with a longitudinal bore. The hollow shafts are sealed at the ends. The hollow shafts or hollow profiles can have any external cross section, in particular a rectangular or round cross section. For introducing lubricant into the hollow shafts, a rotary feedthrough 29 is provided in at least one shaft bearing 30 arranged on the machine frame 3. About the rotary feedthrough 29, the hollow shafts are each connected to one of the lubricant lines 26 of the lubricant distributor 23. In this case, each of the threaded spindles 16 is assigned a separate lubricant line 26. Likewise, each of the guide rails 8 is assigned a separate lubricant line 26 in each case. By means of controllable by the control unit 27 valves 28 thus the hollow shafts are individually, controllably acted upon with lubricant.

An jeweils einer Stelle in Richtung quer zur Transportrichtung 5 ist in jeder der Hohlwellen eine Querbohrung 31 vorgesehen. Durch die Querbohrung 31 wird auf den Hohlwellen jeweils eine Schmier-Position 32 definiert, an welcher Schmierstoff zur Schmierung der Lager aus den Hohlwellen austreten kann. Die Schmier-Position 32 auf der Gewinde-Spindel 16 und die Schmier-Position 32 auf den Führungs-Schienen 8 sind jeweils in Transportrichtung 5 fluchtend zueinander angeordnet, so dass sich der Werkzeugträger 9, wenn er sich an der Schmier-Position 32 der Gewinde-Spindel 16 befindet, auch gerade die Schmier-Position 32 bezüglich der Führungs-Schienen 8 einnimmt.At each point in the direction transverse to the transport direction 5, a transverse bore 31 is provided in each of the hollow shafts. By the transverse bore 31, a lubricating position 32 is defined on the hollow shafts, at which lubricant for lubrication of the bearing can escape from the hollow shafts. The lubricating position 32 on the threaded spindle 16 and the lubricating position 32 on the guide rails 8 are each arranged in the transport direction 5 in alignment with each other, so that the tool carrier 9, when it is in the lubricating position 32 of the thread -Spindle 16, also just the lubricating position 32 with respect to the guide rails 8 occupies.

Zur Schmierung der Lager eines bestimmten Werkzeugträgers 9 muss dieser quer zur Transportrichtung 5 an die Schmier-Position 32 verschoben werden. Hierzu ist die Steuer-Einheit 27 an den Positionier-Motor 18 gekoppelt.To lubricate the bearings of a particular tool carrier 9, this must be moved transversely to the transport direction 5 to the lubricating position 32. For this purpose, the control unit 27 is coupled to the positioning motor 18.

Im Folgenden wird die Funktionsweise der Schmier-Einrichtung 22 beschrieben. Zum automatischen Schmieren der Wellpappe-Bearbeitungs-Vorrichtung 1 wird jeweils einer der Werkzeugträger 9 mittels der vom Positionier-Motor 18 angetriebenen Gewinde-Spindel 16 an die Schmier-Position 32 verschoben. In dieser Position des Werkzeugträgers 9 wird die zu der entsprechenden Gewinde-Spindel 16 führende Schmierstoff-Leitung 26 durch gesteuertes Öffnen ihres zugehörigen Ventils 28 von Schmierstoff-Verteiler 23 mit Schmierstoff beaufschlagt. Der Schmierstoff gelangt vom Schmierstoff-Behälter 24 durch die Drehdurchführung 29 in die als Hohlwelle ausgebildete Gewinde-Spindel 16 und gelangt durch die Längs-Bohrung im Inneren der Gewinde-Spindel 16 zur Querbohrung 31, durch welche er zur Schmierung des Lagers des jeweiligen Werkzeugträgers 9 austritt.The operation of the lubricating device 22 will be described below. For automatically lubricating the corrugated cardboard processing apparatus 1, one of the tool carriers 9 is displaced by means of the threaded spindle 16 driven by the positioning motor 18 to the lubricating position 32. In this position of the tool carrier 9, the leading to the corresponding threaded spindle 16 lubricant line 26 is acted upon by controlled opening of its associated valve 28 of the lubricant distributor 23 with lubricant. The lubricant passes from the lubricant reservoir 24 through the rotary feedthrough 29 into the hollow shaft formed as a threaded spindle 16 and passes through the longitudinal bore in the interior of the threaded spindle 16 to the transverse bore 31, through which he lubrication of the bearing of the respective tool carrier. 9 exit.

Die Schmierung der Lager des Werkzeugträgers 9 auf den Führungs-Schienen 8 erfolgt auf entsprechende Weise.The lubrication of the bearings of the tool carrier 9 on the guide rails 8 takes place in a corresponding manner.

Nach Schmieren der Lager eines Werkzeugträgers 9 wird dieser von der Schmier-Position 32 entfernt, so dass der nächste Werkzeugträger 9 zum Schmieren an die Schmier-Position 32 verschoben werden kann. Die Werkzeugträger 9 werden somit nacheinander zum Schmieren an die Schmier-Position 32 verschoben.After lubricating the bearings of a tool holder 9, this is removed from the lubricating position 32, so that the next tool carrier 9 can be moved to the lubricating position 32 for lubrication. The Tool carrier 9 are thus successively moved to the lubricating position 32 for lubrication.

Das Verschieben der Werkzeugträger 9 ist vorteilhafterweise mittels der Steuer-Einheit 27 automatisiert durchführbar, so dass zum Schmieren der gesamten Wellpappe-Bearbeitungs-Vorrichtung 1 nur noch ein Schmierprogramm über die Steuer-Einheit 27 gestartet werden muss. Da die Wellpappe-Bearbeitungs-Vorrichtung 1 mehr als 100 Werkzeugträger 9 aufweisen kann, deren Lager auf der Gewinde-Spindel 16 und den Führungs-Schienen 8 oftmals nur schwer zugänglich sind, wird durch die mittels der Schmier-Einrichtung 22 durchführbar automatisierte Schmierung der Aufwand hierfür erheblich verringert.The displacement of the tool carrier 9 is advantageously carried out automatically by means of the control unit 27, so that only one lubrication program on the control unit 27 must be started to lubricate the entire corrugated processing apparatus 1. Since the corrugated board processing device 1 may have more than 100 tool carrier 9, the bearings on the threaded spindle 16 and the guide rails 8 are often difficult to access, is by the means of the lubricating device 22 feasible automated lubrication of effort considerably reduced.

Im Folgenden wird unter Bezugnahme auf die Fig. 5 ein zweites Ausführungsbeispiel der Schmier-Einrichtung 22 beschrieben. Identische Teile erhalten dieselben Bezugszeichen wie bei dem ersten Ausführungsbeispiel, auf dessen Beschreibung hiermit verwiesen wird. Konstruktiv unterschiedlich, jedoch funktionell gleichartige Teile erhalten dieselben Bezugszeichen mit einem nachgestellten a. Der Unterschied zum ersten Ausführungsbeispiel besteht darin, dass die Führungs-Schienen 8a mittels einer im Querträger 6a integrierten Schmierstoff-Zuführung 33 mit Schmierstoff versorgt werden. Es ist daher bei diesem Ausführungsbeispiel nicht nötig, die Führungs-Schienen 8a als Hohlwellen auszubilden. Dies ist insbesondere von Vorteil, wenn eine bereits bestehende Wellpappe-Bearbeitungs-Vorrichtung 1 mit bereits vorhandenen Führungs-Schienen 8a mit einer erfindungsgemäßen Schmier-Einrichtung nachgerüstet werden soll. Hierzu müssten lediglich die Schmier-Zuführungen 33 an den Querträgern 6a angebracht und mit den Schmierstoff-Leitungen 26 vom Schmierstoff-Verteiler 23 verbunden sowie die Führungs-Schienen 8a mit den Querbohrungen 31 versehen werden. Gegebenenfalls muss die vorhandene Stellwelle durch eine erfindungsgemäße, hohle Gewinde-Spindel 16 ersetzt werden.The following is with reference to the Fig. 5 A second embodiment of the lubricating device 22 is described. Identical parts are given the same reference numerals as in the first embodiment, to the description of which reference is hereby made. Structurally different, but functionally similar parts receive the same reference numerals with a following a. The difference from the first exemplary embodiment is that the guide rails 8a are supplied with lubricant by means of a lubricant feed 33 integrated in the cross member 6a. It is therefore not necessary in this embodiment, the guide rails 8a form as hollow shafts. This is particularly advantageous if an existing corrugated board processing device 1 is to be retrofitted with already existing guide rails 8a with a lubricating device according to the invention. For this purpose, only the lubricating feeders 33 would have to be attached to the cross members 6a and connected to the lubricant lines 26 from the lubricant distributor 23 and the guide rails 8a with the transverse bores 31 be provided. If necessary, the existing adjusting shaft must be replaced by a hollow threaded spindle 16 according to the invention.
