Abstract

A numerically or manually controlled moving carriage drafting machine with digital X-Y position and angle indication, input keyboard, ruler holder and lowering mechanism for tubular pens or similar writing instruments at the drawing head is particularly characterized in that the drawing head contains an X1-Y1 writer with high dynamic range and small working range only for lettering and small sized symbols whose path instructions are superimposed by the same computer alternately also to the X-Y drives of the moving carriages, and that all movements of the drawing head originate as selected from a movement sensor which is guided manually by the hand of an operator as well as from a path computer, with all operating and path driving programs at least capable of being recalled from the keyboard at the drawing head.

Description

Die Erfindung betrifft eine Laufwagen-Zeichenmaschine gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a carriage drawing machine according to the preamble of claim 1.

Bei rechnergestützten Laufwagen-Zeichenmaschinen werden die Bahninformationen in Form von Analog- oder Digitalwerten kartesischer Koordinaten der Bahnpunkte an die Antriebe ausgegeben, wobei die Bahnbestimmung durch einen Rechner erfolgt., dem die Bahnbeschreibung durch Programmierung in einer geeigneten, regelmässig höheren Programmiersprache mitgeteilt wurde.In the case of computer-aided carriage drawing machines, the path information is output to the drives in the form of analog or digital values of Cartesian coordinates of the path points, the path being determined by a computer to which the path description was communicated by programming in a suitable, regularly higher programming language.

Darüberhinaus sollen rechnergestützte Zeichenmaschinen es dem Konstrukteur jedoch auch ermöglichen, während des Konstruktionsprozesses sowohl wie gewohnt mit im Zeichenkopf befestigten Linealen von Hand positioniert auf der Zeichenfläche zu arbeiten, als auch die Hilfe des Rechners bei der Ausführung einfach beschreibbarer oder ein für allemal beschriebener schwieriger, immer aber schwierig ausführbarer Zeichenoperationen einzusetzen. Er soll durch die Ausstattung der Maschine jederzeit in der Lage sein, Teile seiner Konstruktion zu Stützpunkten einer später abzufahrenden Bahn zu kürzen, Routineprogramme zur Ausführung von zum Beispiel wiederkehrenden Teilen seiner Konstruktion einzusetzen, Ortsbestimmungen versuchsweise vorzunehmen, zum Beispiel zur Optimierung bestimmter Verhältnisse, Schnittflächen zu schraffieren, beliebige Kreis- oder Streckenteilungen oder ähnliches vorzunehmen.In addition, computer-assisted drawing machines should also enable the designer to work with the rulers attached to the drawing head by hand on the drawing surface as usual during the design process, as well as the help of the computer in the execution, which is easy to describe or more difficult, always described but difficult to use drawing operations. By equipping the machine, he should be able at any time to shorten parts of his construction to support points for a path to be traveled later, to use routine programs to carry out, for example, recurring parts of his construction, to carry out location tests on an experimental basis, for example to optimize certain conditions, cut surfaces hatch to make any division of circles or lines or the like.

Der Stand der Technik ist gut gekennzeichnet durch ein Produkt der Firma Wild Heerbrugg AG, CH-9435 Heerbrugg, laut beigefügtem Prospekt. Alle vom Zeichenkopfwagen auszuführenden Bewegungen und Bahnen müssen über einen Rechner programmiert werden, der über RS 232-Anschluss mit den Achsantrieben -der Laufwagen-Zeichenmaschine verbunden ist.The state of the art is well characterized by a product from Wild Heerbrugg AG, CH-9435 Heerbrugg, according to the attached brochure. All movements and trajectories to be carried out by the drawing head carriage must be programmed via a computer which is connected to the axis drives of the carriage drawing machine via an RS 232 connection.

Entsprechend der heute hohen Leistung der in dem jeweils eingesetzten Steuerrechner verfügbaren Programme werden solche automatischen Zeichenmaschinen zur Entwicklung umfangreicher Linienwerke und zur Darstellung komplexer Konstrukionen in den verschiedensten Ansichten und Schnittbahnen verwendet. Dieser Stand der Technik ist unter anderem auch durch Prospekte der Firmen: Aristo, Calomp, Xynetics beschrieben.Corresponding to the high performance of the one used in each case Programs available to control computers, such automatic drawing machines are used for the development of extensive lineworks and for the representation of complex constructions in the most varied of views and cutting paths. This state of the art is also described in brochures from the companies: Aristo, Calomp, Xynetics.

Kennzeichnend für diesen Stand der Technik sind die hohen intellektuellen Anforderungen an den Konstrukteur, die die Bedienung dieser Maschinen stellt, und die bei komplizierten Zeichnungswerken bis zum teilweisen oder vollen Verlust der Übersicht über die Linienwerksprogramme, auf jeden Fall jedoch zu steil zunehmendem Dokumentationsaufwand und damit zu einer Beeinträchtigung der Produktivität der Leistungseinheit Mensch-Maschine führt. Der weit überwiegende Teil aller Konstruktionsarbeiten im allgemeinen Ingenieurwesen wird deshalb auch heute noch an Zeichenbrettern und Zeichenmaschinen geleistet, deren Funktion seit Jahrzehnten unverändert ist.Characteristic of this state of the art are the high intellectual demands placed on the designer by the operation of these machines and, in the case of complicated drawings, up to a partial or complete loss of the overview of the line program, but in any case to a steeply increasing documentation effort and thus impairment of the productivity of the human-machine power unit. The vast majority of all construction work in general engineering is therefore still performed today on drawing boards and drawing machines, the function of which has remained unchanged for decades.

Der entscheidende Nachteil des beschriebenen Standes der Technik besteht nämlich darin, dass durch die räumlich weit auseinanderliegenden Elemente konventioneller CAD-Anlagen für den Konstrukteur ungewohnte und konzentrationsstörende körperliche Bewegungen und Anpassungen des Auges an wechselnde Objektentfernungen notwendig werden, die psychisch stark belasten.The decisive disadvantage of the described prior art is that the spatially widely spaced elements of conventional CAD systems make it necessary for the designer to use unusual and concentration-disrupting physical movements and adapting the eye to changing object distances, which are extremely stressful.

Der Erfindung liegt die Aufgabe zugrunde, Elemente sowohl der konventionellen handgeführten Zeichenmaschine als auch der konventionellen numerisch oder rechnergesteuerten Zeichenmaschine sowie Elemente sogenannter Plotter oder Beschriftungsmaschinen so anzuordnen, dass der Konstrukteur eine wirksame Hilfe von hoher Produktivität bei seiner Arbeit erhält, deren Anwendung für ihn naheliegend ist, weil nicht Einsicht in komplexe Rechnerprogramme, sondern nur Übersicht über das die Konstruktion oder den Plan darstellende Linienwerk von ihm verlangt wird.The invention has for its object to arrange elements of both the conventional hand-held drawing machine and the conventional numerical or computer-controlled drawing machine and elements of so-called plotters or lettering machines so that the designer receives effective help of high productivity in his work, the application of which is obvious to him because not insight into complex computer programs, but only an overview of the construction or the line work representing the plan is required of him.

Es ist von entscheidender Wichtigkeit, Fahrsensor, Digitalanzeige, Rechnertastatur, X1- Y1-Fahrwerk zum Beispiel nach DBP 27 24 855 Justierlupe, Druckbleistift sowie eine zweckmässige Auswahl von Röhrchenfedern räumlich eng benachbart im unmittelbaren Blickfeld des Bedieners einer Laufwagen-Zeichenmaschine nach der vorliegenden Erfindung anzuordnen.It is of crucial importance that the driving sensor, digital display, computer keyboard, X 1 - Y 1 suspension, for example according to DBP 27 24 855, a magnifying glass, mechanical pencil and an appropriate selection of tube springs are spatially closely adjacent in the immediate field of vision of the operator of a carriage drawing machine according to the present To arrange invention.

Die Lösung dieser Aufgabe wird durch die im Kennzeichen des Patentanspruchs 1 beschriebene technische Lehre vermittelt, während die Unteransprüche zweckmässige Ausgestaltungsformen der Erfindung beinhalten.This object is achieved by the technical teaching described in the characterizing part of patent claim 1, while the subclaims contain expedient embodiments of the invention.

Gemäss der Erfindung besitzt die Zeichenmaschine regelbare Antriebe in X- und Y-Richtung, die ihre Sollwerte von einem vorprogrammierten Analog- oder Digitalrechner oder von einem Führungssensor erhalten. Eine herkömmliche Laufwagen-Zeichenmaschine wird in X- und Y-Achse mit massearmen Antrieben hoher Dynamik ausgerüstet, die entweder von der Hand des Bedieners am Fahrsensor der Zeichenmaschine oder vom Rechner der Maschinensteuerung aus Bahnbeschreibungen erzeugte Fahrsignale in Fahrbewegungen umsetzen.According to the invention, the drawing machine has controllable drives in the X and Y directions, which receive their setpoints from a preprogrammed analog or digital computer or from a guide sensor. A conventional carriage drawing machine is equipped in the X and Y axes with low-mass drives of high dynamics, which convert driving signals generated by path descriptions into driving movements either by the operator's hand on the driving sensor of the drawing machine or by the computer of the machine control.

Der Zeichenkopf der so veränderbaren Laufwagen-Zeichenmaschine, der, wie bekannt, mit einer Aufnahme für zwei rechtwinklig zueinander angeordnete Lineale versehen ist, erhält neben einem Fahrsensor eine Tastatur als Eingang in den Steuerrechner und ein zweites, fest eingebautes X1- Y1-Fahrwerk, zum Beispiel nach DBP 27 24 855, eine Kathodenstrahlröhre als rechneransteuerbare Datenausgabe, eine Zentrierlupe, einen Druckbleistift, sowie eine zweckmässige Anzahl von Röhrchenfedern unterschiedlicher Strichbreiten.The drawing head of the so-changeable carriage - drafting machine, which, as is known, provided with a receptacle for two mutually perpendicular rulers, receives alongside a driving sensor, a keyboard as an input into the control computer and a second, fixedly built-X 1 - Y 1 running gear , for example according to DBP 27 24 855, a cathode ray tube as computer-controllable data output, a centering magnifier, a mechanical pencil, and an appropriate number of tube nibs of different line widths.

Um diese erfinderische Anordnung teilweise bekannter, teilweise neuer Hilfsmittel ingenieurmässiger Konstruktion kostengünstig herzustellen, kann es zweckmässig sein, die Steuer- und Auswerteelektronik der Laufwagenachsen dem X1- Y1-Fahrwerk aufzuschalten, solange dort bahngefahren wird, und sie auf das X- Y-Fahrwerk zurückzuschalten, wenn dort Bedarf ist.In order to produce this inventive arrangement of partly known, partly new aids of engineering design inexpensively, it can be expedient to connect the control and evaluation electronics of the carriage axles to the X 1 - Y 1 undercarriage as long as there is rail travel, and to the X, Y, Switch down undercarriage if there is a need.

Weiter kann es zweckmässig sein, auch die Lagerung der Linealaufnahme motorisch drehbar auszubilden, um wie bei den X-Y- bzw. X1- Y1-Antrieben ein manuell oder vom Rechner erzeugtes Steuersignal zu definierten Drehungen der Linealaufnahme zu verarbeiten.Further, it may be advantageous to form the bearing of the intake Linea rotatable motor to as the XY or X 1 - to process a manually or generated by the computer control signal at defined rotations of the Linea intake Y 1 -Antrieben.

Eine weitere Ausführungsform der Erfindung besteht darin, dass im Zeichenkopf einer Laufwagen-Zeichenmaschine mit weg- oder ortsmessenden X-Y-Antrieben alle Ein- und Ausgabeelemente räumlich eng benachbart im direkten Gesichtsfeld des Bedieners angeordnet sind, die für die interaktive Zusammenarbeit mit dem Rechner und für die schrittweise Erstellung von Entwurf und Reinzeichnung am gleichen Ort, dem Arbeitsbereich der Zeichenmaschine, erforderlich sind. Ferner besteht eine weitere Ausführungsform darin, dass die über die Tastatur am Zeichenkopf zugänglichen Betriebsprogramme der Maschine die einfache Übernahme von durch manuelles Verfahren und Justieren des Zeichenkopfes mit dem Fahrsensor gewonnenen Positionen Ortsdaten jedes einzelnen Aus- und Eingabewerkzeuges wie X1-Y1-Schreiber, Schnittpunkt der Ziehkanten des Linealpaares, optische Achse der Zentrierlupe, Bleistift- oder Röhrchenfederachsen erlauben.Another embodiment of the invention is that in the drawing head of a carriage drawing machine with displacement or location-measuring XY drives, all input and output elements are spatially closely adjacent in the direct field of vision of the operator, which are necessary for interactive cooperation with the computer and for step-by-step creation of the draft and final drawing in the same place, the working area of the drawing machine. Furthermore, a further embodiment consists in that the operating programs of the machine accessible via the keyboard on the drawing head make it easy to take over the position data of each individual output and input tool such as X 1 -Y 1 writer obtained by manual movement and adjustment of the drawing head with the travel sensor, Allow intersection of the drawing edges of the ruler pair, optical axis of the centering magnifier, pencil or tube spring axes.

Die mit der erfinderischen Anordnung erzielbaren Vorteile bestehen besonders darin, dass sie sich dem natürlichen Entstehungsprozess einer ingenieurmässigen Konstruktion am Zeichenbrett fast ideal anpasst. Der Fahrsensor am Zeichenkopf gibt der Zeichenmaschine solange das Verhalten einer konventionellen, antriebslosen Laufwagen-Zeichenmaschine, als der Bediener Rechnerhilfe nicht wünscht, wobei jedoch die Ortsdaten jeweils interessierender Aus- oder Eingabewerkzeuge an der Anzeige zur Verfügung stehen können.The advantages that can be achieved with the inventive arrangement are, in particular, that it adapts almost perfectly to the natural process of creation of an engineering construction on the drawing board. As long as the driving sensor on the drawing head gives the drawing machine the behavior a conventional, drive-less carriage drawing machine, when the operator does not want computer assistance, but the location data of the relevant output or input tools can be available on the display.

Vorteilhaft anders verhält sich der Zeichenkopf beim Loslassen des Fahrsensors. Da er keine Fahrsignale liefert, steht der Zeichenkopf und damit die Ziehkanten der Lineale fest. Die Ortsdaten der Ziehkanten oder jedes beliebigen anderen Ausgabewerkzeuges können in der Digitalanzeige verfolgt oder als Stützpunkte eines zu entwickelnden Bahnfahrprogrammes in den Rechner übernommen werden.The drawing head behaves advantageously differently when the driving sensor is released. Since it does not provide any driving signals, the drawing head and thus the drawing edges of the rulers are fixed. The location data of the drawing edges or any other output tool can be tracked in the digital display or transferred to the computer as a base for a rail travel program to be developed.

Erfordert der Arbeitsfortschritt Rechnerhilfe, zum Beispiel für Teilungen, Kreise, trigonometrische Bestimmungen oder für die Ausführung genormter Darstellungselemente, so kann sie über Tastatur abgerufen, über die Anzeige geprüft, mit jedem verfügbaren Zeichenwerkzeug geleistet werden. Ausführung und Fortschritt dieser Systemhilfe erfolgen im bequem überschauberen Gesichtsfeld des Bedieners, der die Ausführung über Tastatur beschleunigen, verzögern oder abbrechen kann.If the work progress requires computer help, for example for divisions, circles, trigonometric determinations or for the execution of standardized display elements, it can be called up via the keyboard, checked via the display, and performed with any available drawing tool. Execution and progress of this system help take place in the operator's comfortably oversized field of vision, which can accelerate, delay or abort the execution using the keyboard.

Besonders wenn gespeicherte, grössen-, form- oder massstabvariable Darstellungselemente aufgabengerecht in Zeichnungen oder Pläne eingefügt werden sollen, ist die Möglichkeit, mit dem Fahrsensor und der Justierlupe feinfühlig im Arbeitsfeld, also in Zeichnung oder Plan, zu positionieren und die Ausführung dem benötigten, nur erschwert oder ungenau optisch positionierbaren Werkzeug per Steueranweisung zuzuordnen, ausserordentlich produktiv.Especially if stored, size, shape or scale-variable display elements are to be inserted in drawings or plans according to the task, it is possible to use the travel sensor and the adjusting magnifier to position the work area, i.e. in the drawing or plan, and to execute the required one difficult to assign or inaccurately optically positionable tool via control instruction, extremely productive.

Ähnliches gilt für wiederkehrende oder einmalige Texte, wenn die Plazierung in der Zeichnung kritisch oder beengt oder von jeweils wechselndem Platzangebot gekennzeichnet ist. Hier kann die einfache Positionierung über Fahrsensor und die Beschränkung der beschreibbaren Fläche durch Angabe der Grenzen sehr zeitsparend sein. Reinzeichnen von Umrissen, Schnitten, Schraffuren, axiometrischen Darstellungen können ähnlich effektiv durch Interaktion zwischen Maschine und Mensch ausgeführt werden.The same applies to recurring or one-off texts if the placement in the drawing is critical or cramped or is characterized by changing space. Here is the simple position tion via the driving sensor and the limitation of the writable area by specifying the limits can be very time-saving. Drawing in outlines, cuts, hatching, axiometric representations can be carried out just as effectively through interaction between machine and human.

Eine Ausführungsform der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.

Die horizontale Führungsbahn 1 enthält einen zum Beispiel nach der eigenen noch nicht offengelegten Patentanmeldung P 31 04 962.1-27 angetriebenen, in der Zeichnung nicht dargestellten Führungswagen, an dem die Führungsbahn 2 starr und biegesteif befestigt ist. Auch die Führungsbahn 2 enthält wie die Führungsbahn 1 einen ebenfalls nicht dargestellten Führungswagen, an dem der Zeichenkopf 3 befestigt ist. Führungsbahn 1 stellt dabei die X-Achse, Führungsbahn 2 die Y-Achse der Zeichenmaschine dar. Die FÜhrungsbahn 1 ist ihrerseits an zum Beispiel einem Zeichenbrett 15, wie allgemein bekannt, befestigt, das Zeichenbrett neigbar oder fest in zweckmässiger Höhe vor dem Zeichner aufgestellt.The horizontal guideway 1 contains, for example, a guide carriage, not shown in the drawing, to which the guideway 2 is fixed rigidly and rigidly, for example according to its own as yet unpublished patent application P 31 04 962.1-27. The guideway 2, like the guideway 1, also contains a guide carriage, also not shown, to which the drawing head 3 is attached. Guideway 1 represents the X-axis, guideway 2 the Y-axis of the drawing machine. The guideway 1 is in turn attached to, for example, a drawing board 15, as is generally known, the drawing board can be tilted or set up in a suitable height in front of the draftsman.

Der Zeichenkopf 3 am Laufwagen der Führungsbahn 2 enthält für die Bedienung mit der linken Hand den für vektoriellen Druck in Fahrrichtung empfindlichen Fahrsensor 11 und den drehmomentempfindlichen Drehsensor 10, für die Erzeugung der Fahrsignale, für die Bewegung des Zeichenkopfes 3 oder für die Drehung des Linealwinkels 5, 6. Ferner sind auf der bedienerseitigen Frontfläche des Zeichenkopfes die Tastatur 13, sowie die Matrixpunkt- oder Kathodenröhrenanzeigen 12 angebracht.The drawing head 3 on the carriage of the guideway 2 contains the driving sensor 11 sensitive to vector pressure in the direction of travel and the torque-sensitive rotation sensor 10 for the operation with the left hand, for generating the driving signals, for the movement of the drawing head 3 or for the rotation of the ruler angle 5 , 6. Furthermore, the keyboard 13 and the matrix dot or cathode tube displays 12 are attached to the operator's front surface of the drawing head.

Bedienerhandabgewandt, jedoch im nahen Gesichtsfeld des Bedieners und betätigt von Abhebemechanismen im inneren des Zeichenkopfes, befinden sich ein X1- Y1-Fahrwerk 7, eine Bleistiftaufnahme 8, eine Justierlupe 9 sowie zum Beispiel Röhrchenfedern 4 verschiedener Strichstärken, die beispielsweise nach der eigenen noch nicht offengelegten Patentanmeldung P 31 44 057.6 angeordnet sein können.Averted from the operator's hand, but in the near field of vision of the operator and actuated by lifting mechanisms inside the drawing head, there are an X 1 - Y1 carriage 7, a pencil holder 8, an adjusting magnifier 9 and, for example, tube springs 4 of different line widths, which, for example, are not yet available published patent application P 31 44 057.6 can be arranged.

Sollen sich die Bewegungen in X-Achse durch besondere Dynamik auszeichnen, so kann es zweckmässig sein, eine Führungsbahn 1' vorzusehen, darin einen ebenfalls nicht dargestellten Führungswagen anzuordnen, an dem die Führungsbahn 2 bei a so befestigt ist, dass rechte Winkel zwischen 1, l'und 2 auch bei jeder für den Betrieb vorgesehenen Beschleunigung und Verzögerung ebenso gesichert sind wie Parallelverschiebung von Führungsbahn 2.If the movements in the X-axis are to be distinguished by special dynamics, it may be expedient to provide a guideway 1 ', to arrange therein a guide carriage, likewise not shown, to which the guideway 2 is fastened at a in such a way that right angles between 1, l'and 2 are also secured with every acceleration and deceleration intended for operation, as is parallel displacement of guideway 2.
