Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines als prismatischer Hohlkörper ausgebildeten Trägers, dessen Wände durch Zusammenfügen von jeweils in Längsrichtung des Trägers hintereinander angeordneten Obergurtmodulen, Untergurtmodulen, Frontwandmodulen und Rückwandmodulen gebildet werden, wobei im Inneren des Trägers in Abständen Querstege angeordnet werden und wobei am Träger mindestens eine in seiner Längsrichtung verlaufenden Führungsbahn für eine längs der Führungsbahn bewegliche Baugruppe angeordnet wird.The invention relates to a method for producing a carrier designed as a prismatic hollow body whose walls are formed by joining each in the longitudinal direction of the carrier successively arranged Obergurtmodulen, Untergurtmodulen, front wall modules and rear wall modules, wherein in the interior of the carrier at intervals transverse webs are arranged and wherein the carrier at least one guide track running in its longitudinal direction is arranged for an assembly movable along the guide track.

Aus der Patentanmeldung US2007/0000886A1 ist ein Verfahren zur Herstellung eines Trägers und eines Maschinenbetts einer Werkzeugmaschine bekannt. Die Werkzeugmaschine hat einen auf Führungsbahnen eines Trägers verfahrbaren Schlitten, der einen Bearbeitungskopf trägt. Der Träger ist seinerseits auf Führungsbahnen des Maschinenbettes verfahrbar. Im Dokument ist eine Technik zur einfachen Herstellung des Trägers und des Maschinenbetts durch Zusammenbauen aus Blechteilen beschrieben, welche mittels Laserstrahlen zugeschnitten wurden.From the patent application US2007 / 0000886A1 For example, a method for producing a carrier and a machine bed of a machine tool is known. The machine tool has a slide which can be moved on guideways of a carrier and which carries a machining head. The carrier is in turn movable on guideways of the machine bed. The document describes a technique for easily manufacturing the carrier and the machine bed by assembling sheet metal parts cut by means of laser beams.

Die Technik der Bewegung eines Bearbeitungskopfes, der verschiebbar auf einem Träger gelagert ist, wobei der Träger gegebenenfalls selbst in einer Richtung quer zu seiner Längsachse beweglich ist, findet nicht nur bei Werkzeugmaschinen Anwendung, sondern beispielsweise auch bei Plottern und Druckern, wobei der Bearbeitungskopf in diesen Fällen ein Druckkopf ist. In allen Fällen geht es darum, den Träger möglichst präzise und biegesteif bei möglicht geringer Masse zu gestalten.The technique of moving a machining head that is slidably mounted on a carrier, which carrier is itself movable in a direction transverse to its longitudinal axis, not only applies to machine tools, but also, for example, in plotters and printers, wherein the machining head in this Cases is a printhead. In all cases, it is important to make the carrier as precise and rigid as possible with the lowest possible mass.

Die vorliegende Erfindung hat die Aufgabe, ein Verfahren zur Herstellung eines gattungsgemäßen Trägers vorzuschlagen, dessen mindestens eine Führungsbahn verglichen mit den Führungsbahnen bekannter Träger eine erhöhte Präzision aufweist. Das Herstellungsverfahren soll dabei mit einem gegenüber dem bekannten Stand der Technik reduzierten herstellungs- und maschinentechnischen Aufwand ausführbar sein.The object of the present invention is to propose a method for the production of a generic carrier whose at least one guideway has an increased precision compared with the guideways of known carriers. The manufacturing process is intended to be executable with a reduced manufacturing and mechanical complexity compared to the known prior art.

Die Lösung dieser Aufgabe der Erfindung wird erfindungsgemäß dadurch erreicht, dass die mindestens eine Führungsbahn gebildet wird, indem Bereiche der Module nach dem Zusammenfügen der Module und Querstege spanabhebend bearbeitet werden.The solution of this object of the invention is inventively achieved in that the at least one guideway is formed by machining areas of the modules after assembly of the modules and transverse webs are machined.

Der sich durch dieses Verfahren ergebende Vorteil besteht darin, dass sich damit verglichen mit bekannten Herstellungsverfahren eine höhere Präzision der Führungsbahn erreichen lässt.The advantage resulting from this method is that a higher precision of the guideway can be achieved compared with known production methods.

Die Erfindung betrifft auch einen nach dem erfindungsgemäßen Verfahren hergestellten Träger.The invention also relates to a carrier produced by the process according to the invention.

Die Erfindung betrifft auch einen weiteren als prismatischer Hohlkörper ausgebildeten Trägers der eingangs genannten Art.The invention also relates to a further designed as a prismatic hollow body carrier of the type mentioned.

Die Aufgabe, einen Träger mit mindestens einer Führungsbahn mit hoher Präzision zur Verfügung zu stellen, wird bei diesem weiteren Träger dadurch gelöst, dass die mindestens eine Führungsbahn durch mindestens ein sich über die Länge von mehreren Modulen erstreckendes Profil gebildet ist.The task of providing a carrier with at least one guideway with high precision is achieved in this further carrier in that the at least one guideway is formed by at least one over the length of several modules extending profile.

Der sich durch diese Maßnahmen ergebende Vorteil besteht darin, dass damit die Führungsbahnen, verglichen mit den Führungsbahnen bekannter zusammengesetzter Träger, eine höhere Präzision aufweisen.The advantage resulting from these measures is that the guideways have a higher precision compared with the guideways of known composite carriers.

Nach einer Ausführungsart sind die Module in Längsrichtung des Trägers gegeneinander versetzt sind, derart, dass Stellen, an denen zwei in Längsrichtung des Trägers hintereinander angeordnete Module aneinander stoßen, nicht mit Stellen fluchten, an denen zwei in Längsrichtung des Trägers hintereinander angeordnete Module der benachbarten Wand des Trägers aneinander stoßen. Damit wird insbesondere erreicht, dass die Biegesteifigkeit des Trägers über seine Länge keine Schwankungen aufweist.According to one embodiment, the modules are offset in the longitudinal direction of the carrier against each other, such that locations where two consecutively arranged in the longitudinal direction of the carrier modules abut each other, not aligned with locations where two in the longitudinal direction of the carrier successively arranged modules of the adjacent wall of the carrier abut each other. This is achieved in particular that the flexural rigidity of the carrier over its length has no fluctuations.

Vorteilhaft ist auch eine weitere Ausführungsform, bei der die Module unter sich und/oder die Module und die Querstege aus unterschiedlichen Werkstoffen bestehen. Damit kann den Träger den jeweiligen Anforderungen entsprechend hinsichtlich seines Biegeverhaltens und seines Verhaltens bei Temperaturänderungen weiter verbessert werden.Also advantageous is a further embodiment in which the modules consist of different materials and / or the modules and the transverse webs. Thus, the carrier can be further improved according to the respective requirements with regard to its bending behavior and its behavior in the event of temperature changes.

Gemäß einer anderen Ausführungsart sind die Module unter sich und/oder die Module und die Querstege miteinander durch Kleben verbunden. Dadurch kann der Träger besonders einfach und kostengünstig zusammengebaut werden. Wenn nach einer zusätzlichen Ausführungsart in den Klebefugen Kohlefasern eingebunden sind, wird die Steifigkeit des Trägers weiter erhöht.According to another embodiment, the modules are connected to each other and / or the modules and the transverse webs by gluing. This makes the carrier particularly easy and inexpensively assembled. If, according to an additional embodiment, carbon fibers are incorporated in the glue joints, the rigidity of the carrier is further increased.

Vorteilhaft sind auch Ausführungsarten, bei welchen die Module unter sich und/oder die Module und die Querstege miteinander durch Stifte und/oder Schrauben verbunden sind.Also advantageous are embodiments in which the modules are connected to each other and / or the modules and the transverse webs with each other by pins and / or screws.

Schließlich sieht eine weitere Ausführungsart vor, dass im Inneren des Trägers in Längsrichtung verlaufende, vorgespannte Zugmittel angeordnet sind. Die Vorspannung beeinflusst das Biegeverhalten des Trägers unter Last und Temperaturänderungen günstig.Finally, a further embodiment provides that in the interior of the carrier in the longitudinal direction, biased traction means are arranged. The bias affects the bending behavior of the carrier under load and temperature changes favorably.

Die Erfindung wird im nachfolgenden anhand der in den Zeichnungen dargestellten Ausführungsbeispiele näher erläutert.The invention will be explained in more detail below with reference to the embodiments illustrated in the drawings.

Also, the position information selected in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to a new position analogous to the new situation.

Der in Fig. 1 an Hand eines Ausschnitts illustrierte Träger 1 enthält einen aus in Längsrichtung des Trägers 1 hintereinander angeordneten Obergurtmodulen 2 zusammengesetzten Obergurt, einen aus in Längsrichtung des Trägers 1 hintereinander angeordneten Untergurtmodulen 3 zusammengesetzten Untergurt, eine aus in Längsrichtung des Trägers 1 hintereinander angeordneten Frontwandmodulen 4 zusammengesetzte Frontwand und eine aus in Längsrichtung des Trägers 1 hintereinander angeordneten Rückwandmodulen 5 zusammengesetzte Rückwand. Im Inneren des Trägers 1 sind in abständen Querstege 6 angeordnet, die rechtwinklig zu den genannten Modulen angeordnet und mit diesen verbunden sind.The in Fig. 1 Carrier 1 illustrated on the basis of a cutout comprises a top chord composed of upper chord modules 2 arranged one behind the other in the longitudinal direction of the carrier 1, a bottom chord composed of bottom chord modules 3 arranged one behind the other in the longitudinal direction of the carrier 1, a front wall composed of front panel modules 4 arranged one behind the other in the longitudinal direction of the carrier 1 a composed of in the longitudinal direction of the carrier 1 successively arranged rear wall modules 5 rear wall. In the interior of the carrier 1 transverse webs 6 are arranged at intervals, which are arranged at right angles to said modules and connected thereto.

In Fig. 1 ist deutlich zu sehen, dass die verschiedenen Module 2, 3, 4, 5 in Längsrichtung des Trägers 1 gegeneinander versetzt sind, derart, dass beispielsweise die Stelle, an der zwei hintereinander angeordnete Obergurtmodule 2 aneinender stoßen, nicht in der selben Querschnittsebene des Trägers liegt wie die Stelle, an der zwei hintereinander angeordnete Frontwandmodule 4 aneinander stoßen. Dadurch wird die Biegestabilität des Trägers 1 über seine Länge konstant gehalten. Wie man in Fig. 1 sieht, hat der Versatz der Module zur Folge, dass im Endbereich des Trägers beispielsweise das Frontwandmodul 4 (links in Fig. 1) kürzer ist als das ihm benachbarte Frontwandmodul. Die Module 2, 3, 4, 5 sind miteinander verbunden, insbesondere durch Kleben. Zusätzlich werden die Module bevorzugt durch Stifte oder Schrauben miteinander verbunden. Die Verbindung der Module durch Stifte verbessert insbesondere die Positioniergenauigkeit der Module untereinander. Zur Illustration der zusätzlichen Verbindung mit Stiften oder Schrauben sind in Fig. 1 Befestigungslöcher 16 in den Obergurtmodulen 2 und Befestigungslöcher 17 in den Frontwandmodulen 4 bezeichnet. Auch in den Querstegen 6 können Befestigungs- oder Positionierlöcher vorgesehen sein. An Stelle von Klebeverbindungen könnten zwischen den Modulen 2, 3, 4, 5 auch Schweiß- oder Lötverbindungen vorgesehen sein. Dies ist aber wegen der damit verbundenen Erwärmung der Teile im Hinblick auf die angestrebte hohe Präzision der Führungsbahnen nicht besonders vorteilhaft. Je nach Anforderungen, die an den Träger 1 gestellt werden, können für die verschiedenen Module 2, 3, 4, 5 unterschiedliche Werkstoffe verwendet werden. Als Maßnahme zur weiteren Erhöhung der Steifigkeit des Trägers 1 können in die Klebestellen zwischen den Modulen Kohlenstofffasern eingelegt werden.In Fig. 1 It can clearly be seen that the various modules 2, 3, 4, 5 are offset from each other in the longitudinal direction of the carrier 1, such that, for example, the point at which two upper belt modules 2 arranged one behind the other do not lie in the same cross-sectional plane of the carrier as the point where two successively arranged front wall modules 4 abut each other. As a result, the bending stability of the carrier 1 is kept constant over its length. How to get in Fig. 1 sees, the offset of the modules has the consequence that in the end of the carrier, for example, the front wall module 4 (left in Fig. 1 ) is shorter than the adjacent front wall module. The modules 2, 3, 4, 5 are connected to each other, in particular by gluing. In addition, the modules are preferably connected together by pins or screws. The connection of the modules by pins in particular improves the positioning accuracy of the modules with each other. To illustrate the additional connection with pins or screws are in Fig. 1 Fixing holes 16 in the top flange 2 and mounting holes 17 in the front wall modules 4 referred. Also in the transverse webs 6 fastening or positioning holes can be provided. Instead of adhesive bonds between the modules 2, 3, 4, 5 and welding or solder joints could be provided. However, this is not particularly advantageous because of the associated heating of the parts in view of the desired high precision of the guideways. Depending on the requirements placed on the carrier 1, different materials can be used for the different modules 2, 3, 4, 5. As a measure to further increase the rigidity of the carrier 1 carbon fibers can be inserted into the splices between the modules.

Weiter geht aus Fig. 1 hervor, dass in den Modulen 2, 3, 4, 5 Aussparungen vorhanden sein können, beispielsweise Aussparungen 13 in den Querstegen 6, Aussparungen 14 in den Rückwandmodulen 5 und Aussparungen 15 in den Frontwandmodulen 4. Diese Aussparungen dienen in erster Linie dazu, die Masse des Trägers 1 zu reduzieren, ohne dabei seine Steifigkeit zu verringern.Next goes out Fig. 1 that in the modules 2, 3, 4, 5 recesses may be present, for example, recesses 13 in the transverse webs 6, recesses 14 in the rear wall modules 5 and recesses 15 in the front wall modules 4. These recesses serve primarily to reduce the mass of the carrier 1 without reducing its rigidity.

Schließlich ist in Fig. 1 eine erste Führungsbahn 7 dargestellt, die sich über die Oberseiten der Untergurtmodule 3 in Längsrichtung des Trägers 1 erstreckt. Über die oberen Längskanten der Frontwandmodule 4 erstreckt sich eine zweite Führungsbahn 9. Die Aufgabe der Führungsbahnen 7, 9 besteht darin, als Laufbahn für eine längs des Trägers 1 bewegliche Baugruppe, beispielsweise einen Druckkopf zu dienen. Da gerade bei Großformat-Druckem an diese Führungsbahnen besonders hohe Anforderungen hinsichtlich ihrer Präzision gestellt werden, werden diese erst nach dem Zusammenbau des Trägers 1 über die gesamte Länge des Trägers spanabhebend bearbeitet, beispielsweise gefräst, geschliffen, geläppt oder geschabt. Im Übrigen können natürlich auch an den Obergurtmodulen 2 und/oder den Rückwandmodulen 5 Führungsbahnen vorhanden sein.Finally, in Fig. 1 a first guideway 7 is shown, which extends over the upper sides of the lower chord modules 3 in the longitudinal direction of the carrier 1. A second guideway 9 extends over the upper longitudinal edges of the front wall modules 4. The purpose of the guideways 7, 9 is to serve as a raceway for a subassembly movable along the carrier 1, for example a printhead. Since particularly high demands are placed on these guideways with regard to their precision, especially in the case of large-format printing, these are only machined, for example milled, ground, lapped or scraped, over the entire length of the carrier after assembly of the carrier 1. Incidentally, of course, 5 guideways may also be present on the upper belt modules 2 and / or the rear wall modules.

In der Querschnittsdarstellung der Fig. 2 ist deutlich die Anordnung der ersten Führungsbahn 7 an der Oberseite der Untergurtmodule 3 zu sehen, die seitwärts über die Frontwandmodule 4 hinaus ragen. Auch sieht man, dass die zweite Führungsbahn 9 über die Oberkante der Frontwandmodule 4 verläuft, welche Oberkante vertikal über die Obergurtmodule 2 hinaus ragt. Durch diese Gestaltung liegen die Führungsflächen frei und können problemlos einer spanabhebenden Präzisionsbearbeitung unterzogen werden.In the cross-sectional representation of Fig. 2 clearly shows the arrangement of the first guide track 7 at the top of the lower flange modules 3, which protrude laterally beyond the front wall modules 4 addition. It can also be seen that the second guide track 9 extends over the upper edge of the front wall modules 4, which upper edge projects vertically beyond the upper belt modules 2. With this design, the guide surfaces are free and can be easily subjected to a precision machining.

Fig. 2 zeigt ferner, dass die Ecken der Querstege 6 gebrochen sind, wodurch sich über die gesamte Länge des Trägers 1 verlaufende Eckräume 1 ergeben. In diesen Eckräumen befinden sich Zugmittel 12, beispielsweise Stahlseile oder Kohlenfaserbündel. Diese Zugmittel sind in den stirnseitigen Enden des Trägers 1 verankert und vorgespannt, wodurch die Steifigkeit des Trägers 1 zusätzlich erhöht wird und das Biegeverhalten des Trägers unter Last positiv beeinflusst werden kann. Fig. 2 further shows that the corners of the transverse webs 6 are broken, resulting in over the entire length of the support 1 extending corner spaces 1. In these corner spaces are traction means 12, such as steel cables or carbon fiber bundles. This traction means are anchored and biased in the front ends of the carrier 1, whereby the rigidity of the carrier 1 is additionally increased and the bending behavior of the carrier can be positively influenced under load.

Fig. 3 zeigt eine andere Möglichkeit zur Erreichung der geforderten hohen Präzision der Führungsbahnen, indem letztere als mit dem Träger 1 verbundene Präzisionsprofile ausgebildet sind. Ein erstes Profil 8 ist an über die Frontwand vorstehenden Bereichen der Untergurtmodule 3 angeordnet und ein zweites Profil 10 ist auf die oberen Längskanten der Frontwandmodule 4 aufgesetzt. Die Profile 8, 9 können ebenfalls durch Kleben mit den entsprechenden Modulen des Trägers 1 verbunden und durch Stifte und/oder Schrauben zusätzlich positioniert und gesichert sein und erstrecken sich über die Länge mehrerer Module, vorzugsweise über die gesamte Länge des Trägers. Fig. 3 shows another way to achieve the required high precision of the guideways by the latter are formed as connected to the carrier 1 precision profiles. A first profile 8 is disposed on over the front wall projecting portions of the lower flange modules 3 and a second profile 10 is on the upper longitudinal edges of the front wall modules 4 attached. The profiles 8, 9 can also be adhesively bonded to the respective modules of the carrier 1 and additionally positioned and secured by pins and / or screws and extend along the length of several modules, preferably over the entire length of the carrier.

Ein für einen Großformat-Drucker verwendeter erfindungsgemäßer Träger kann beispielsweise folgende Abmessungen haben. Länge 6'000 mm, Höhe 400 mm und Breite 300 mm.A carrier according to the invention used for a large-format printer may, for example, have the following dimensions. Length 6'000 mm, height 400 mm and width 300 mm.

Die Ausführungsbeispiele zeigen mögliche Ausführungsvarianten des Trägers, wobei an dieser Stelle bemerkt sei, dass die Erfindung nicht auf die speziell dargestellten Ausführungsvarianten derselben eingeschränkt ist, sondern vielmehr auch diverse Kombinationen der einzelnen Ausführungsvarianten untereinander möglich sind und diese Variationsmöglichkeit aufgrund der Lehre zum technischen Handeln durch gegenständliche Erfindung im Können des auf diesem technischen Gebiet tätigen Fachmannes liegt.
