Description

Die Erfindung betrifft ein Zeichenbrett mit einem Plotter, d.h. einem steuerbar bewegbar angeordneten Zeichenstift, wobei der Plotter über das Zeichenbrett bewegbar ist.The invention relates to a drawing board with a plotter, i.e. a controllably movable drawing pen, the plotter being movable over the drawing board.

Zum Erstellen und Ändern von Konstruktionszeichnungen werden neben herkömmlichen Zeichenbrettern auch Computer mit Plottern eingesetzt.In addition to conventional drawing boards, computers with plotters are also used to create and change construction drawings.

Auf Zeichenbrettern, auf denen in der Regel Zeichnungen bis zur Formatgröße DIN AO erstellt werden können, zeichnet der Konstrukteur von Hand mit Hilfe von über das Zeichenbrett verschiebbaren Linealen, Zirkeln und Schablonen. Diese solcherart erstellten Zeichnungen können dann digitalisiert und in einen Computer, der ein spezielles Programm, ein sogenanntes CAD-Programm, besitzt, eingegeben werden.The designer draws on drawing boards, on which drawings up to DIN AO size can usually be drawn, by hand using rulers, compasses and stencils that can be moved over the drawing board. These drawings created in this way can then be digitized and entered into a computer which has a special program, a so-called CAD program.

Im Computer abgespeicherte und mittels eines Bildschirms überarbeitete, respektive geänderte Zeichnungen können mit einem Plotter ausgedruckt werden. Dafür stehen Plotter mit verschiedenen Formaten zur Verfügung. Je nach Größe des Papierformates der Zeichnung und damit des Formates des Plotters sind die Kosten eines Plotters verschieden groß. Ein Plotter für das Zeichenformat DIN AO kostet derzeit mindestens DM 40 000,-. Zu diesen Plotterkosten kommen noch die Kosten des Computers selbst mit seiner Software, der Speichereinrichtungen, sowie gegebenenfalls die Kosten eines sogenannten Graphik- oder Digitalisierungstabletts. Damit muß mit Systemkosten von mindestens DM 55 000,- gerechnet werden. Mit einem solchen System erhält man lediglich den Arbeitsplatz für einen einzelnen Zeichner, wenngleich der eigentliche Computer bei größeren Computern und größeren Speichereinrichtungen - bei höheren Kosten derselben - auch für mehrere Arbeitsplätze benutzt werden kann. Kleinere Unternehmen können sich deshalb in der Regel solche Systeme für DIN AO Formate nicht leisten.Drawings saved in the computer and revised or changed on a screen can be printed out with a plotter. Plotters with different formats are available for this. Depending on the size of the paper format of the drawing and thus the format of the plotter, the costs of a plotter vary. A plotter for the DIN AO drawing format currently costs at least DM 40,000. In addition to these plotter costs, there are also the costs of the computer itself with its software, the storage devices, and, if appropriate, the costs of a so-called graphics or digitizing tablet. This means that system costs of at least DM 55,000 must be expected. With such a system one only obtains the workstation for a single draftsman, although the actual computer can be used for larger computers and larger storage devices - at higher costs - for several workplaces. Smaller companies can therefore generally not afford such systems for DIN AO formats.

Es gibt nun auch Zeichensysteme bestehend aus einem Computer mit Eingabetastatur und Speichereinrichtungen, Graphiktablett und Plotter für DIN A3 Blattformat, deren Preise bei mindestens DM 30 000,- liegen. Mit diesen Systemen können aber keine DIN AO Blattformate bearbeitet werden, auch kann in der Regel in den Plotter nur ein Blatt des Formates DIN A3 eingelegt werden.There are now also drawing systems consisting of a computer with an input keyboard and storage devices, graphics tablet and plotter for A3 sheet format, the prices of which are at least DM 30,000. With these systems, however, no DIN AO sheet formats can be processed, and usually only one sheet of DIN A3 format can be inserted into the plotter.

Es gibt nun Plotter, die zwar auch nur einen Zeichenbereich von DIN A3 aufweisen, die aber auf ein grösseres Zeichenblatt aufgelegt werden können und dort verschoben werden können. Diese Plotter weisen eine Eingabetastatur auf, mit der der Zeichenstift bewegt werden kann. Diese Plotter sind relativ preiswert und sie können mit entsprechender Anwender-Software auch mittels sogenannter Micro- oder Personal-Computer, die schon in vielen Schreib- und Zeichen-Büros vorhanden sind, betrieben werden. Mittels dieser Plotter können verschiedene Einzelzeichnungen des maximalen Formates DIN A3 auf einem größeren Blatt gezeichnet werden. Der Plotter wird auf diesem größeren Zeichenblatt von Hand verschoben und ausgerichtet. Es ist aber bei dieser Arbeitsweise nicht möglich, eine Figur zu zeichnen, die größer ist, als das vom Plotter zu verarbeitende DIN A3 Format.There are now plotters that have only a drawing area of A3, but that can be placed on a larger drawing sheet and can be moved there. These plotters have an input keyboard with which the drawing pen can be moved. These plotters are relatively inexpensive and they can also be operated with the appropriate user software using so-called micro- or personal computers, which are already available in many writing and drawing offices. Using these plotters, various individual drawings of the maximum format DIN A3 can be drawn on a larger sheet. The plotter is moved and aligned by hand on this larger drawing sheet. However, with this method of working it is not possible to draw a figure that is larger than the DIN A3 format to be processed by the plotter.

Ein solcher bekannter Plotter wird z.B. von der Firma Rotring Technik GmbH unter der Bezeichnung "NC-plotscriber" vertrieben. Dazu gibt es verschiedene Steuereinheiten und auch ein CAD-System (Bildschirm-Zeichnungserstellungssystem). Auch dieses System ist sehr teuer.Such a known plotter is e.g. distributed by Rotring Technik GmbH under the name "NC-plotscriber". There are various control units and a CAD system (screen drawing system). This system is also very expensive.

Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Zeichenbrett zu schaffen, mit dem Zeichnungen des Formates DIN AO preiswerter erstellt werden können.The invention has for its object to provide a generic drawing board with which drawings of the format DIN AO can be created cheaper.

Diese Aufgabe wird durch den Gegenstand des Anspruches 1 gelöst. Die Gesamtfläche des Zeichenbrettes wird in mehrere Felder eingeteilt, die einander mindestens berühren oder sogar geringfügig überschneiden und denen der Plotter fest zuordenbar ist.This object is solved by the subject matter of claim 1. The total area of the drawing board is divided into several fields that at least touch or even slightly overlap each other and to which the plotter can be firmly assigned.

Ein wesentliches Element der Erfindung ist ein Plotter, der sich gegenüber einem Zeichenbrett in verschiedenen, exakt bestimmbaren Stellungen festlegen läßt.An essential element of the invention is a plotter that can be set in different, precisely definable positions relative to a drawing board.

Dieser Plotter besitzt keine eigene Auflageflä- - che für das Papier, sondern er wird auf ein Zeichenblatt aufgelegt, welches flächenmäßig viel größer ist, als der Plotter. Der Plotter darf also im Bereich seines Zeichenbereiches keinen Boden aufweisen, d.h. er besitzt einen nach unten offenen Rahmen. Ein solcher Plotter besteht im wesentlichen aus einem rechteckigen Rahmen, in dem in der einen zu einem Paar von Seitenkanten parallelen Richtung eine Führungsschiene verschiebbar angeordnet ist, deren Längserstreckung quer zu diesen Seitenkanten liegt. An dieser Führungsschiene entlang ist / sind ein oder mehrere Zeichenstift(e) verfahrbar und senkrecht zur Erstreckungsebene des Rahmens heb- und senkbar gelagert. Ein Plotter mit einem nach unten offenen Rahmen ist als solches bekannt (vgl. "NC-plotscriber" der Fa. Rotring Technik GmbH).This plotter does not have its own support surface for the paper, but is placed on a drawing sheet, which is much larger in area than the plotter. The plotter must therefore have no floor in the area of its drawing area, i.e. it has a frame that is open at the bottom. Such a plotter essentially consists of a rectangular frame in which a guide rail is arranged displaceably in the direction parallel to a pair of side edges, the longitudinal extent of which is transverse to these side edges. Along this guide rail, one or more drawing pen (s) can be moved and can be raised and lowered perpendicularly to the plane of extent of the frame. A plotter with a frame that is open at the bottom is known as such (cf. "NC-plotscriber" from Rotring Technik GmbH).

Der nun hier verwendete Plotter muß jedoch noch Mittel zum festen Zuordnen zu einem bestimmten und bestimmbaren Feld des Zeichenbrettes aufweisen, d.h. der Plotter darf nicht, wie der bekannte Plotter, über dem Zeichenbrett völlig frei verschiebbar sein. Diese Mittel gestatten es, den Plotter gegenüber den einzelnen Feldern exakt auszurichten und zu halten. Solche Mittel können am Zeichenbrett festgelegte Stifte sein, die in Bohrungen eingreifen können, die entweder unmittelbar am Plotter oder an einem mit dem Plotter fest verbundenen Bauteil vorgesehen sind. Es können aber auch sowohl am Zeichenbrett, als auch am Plotter Bohrungen vorgesehen sein, die zur Flucht gebracht werden und durch die zum Arretieren des Plotters gegenüber dem Zeichenbrett Stifte od.dgl. schiebbar sind.However, the plotter now used here must still have means for permanent assignment to a specific and determinable field of the drawing board, i.e. the plotter, like the well-known plotter, must not be able to move freely over the drawing board. These means allow the plotter to be precisely aligned and held in relation to the individual fields. Such means can be pens fixed on the drawing board, which can engage in bores that are provided either directly on the plotter or on a component that is firmly connected to the plotter. But it can also be provided both on the drawing board, and on the plotter holes, which are brought to escape and through the pens or the like for locking the plotter against the drawing board. are slidable.

Ein solcher Plotter besitzt vorzugsweise auch ein Tastenfeld, über das Steuerbefehle für den / die Zeichenstift(e) eingebbar sind.Such a plotter preferably also has a keypad via which control commands for the drawing pen (s) can be entered.

Aus der WO-A 8 502 150, die als Stand der Technik nach EPÜ Art. 54 (3) gilt, ist eine Zeichenmaschine bekannt, die eine erste Laufwagenanordnung enthält, an der eine zweite Laufwagenanordnung befestigt ist. Diese zweite Laufwagenanordnung besitzt zwei motorisch antreibbare Laufwagen, von denen einer einen Arbeitskopf aufweist, der einen Zeichenstift enthalten kann. Der Zeichenstift kann mittels dieser zweiten Laufwagenanordnung in einem sogenannten Aktivbereich bewegt werden, während mit der ersten Laufwagenanordnung der Aktivbereich festgelegt werden kann. Dieser Aktivbereich kann mittels von Meßwertgebern aufgenommenen Daten einem Rechner vermittelt werden. Mittels Bremsen kann die zweite Laufwagenanordnung in einem beliebigen, bestimmbaren Aktivbereich festgehalten werden.A drawing machine is known from WO-A 8 502 150, which is considered prior art under EPC Art. 54 (3), which contains a first carriage arrangement to which a second carriage arrangement is attached. This second carriage arrangement has two motor-driven carriages, one of which has a working head, which can contain a drawing pen. The drawing pen can be moved in a so-called active area by means of this second carriage arrangement, while the active area can be defined with the first carriage arrangement. This active area can be conveyed to a computer by means of data recorded by sensors. The second carriage arrangement can be held in any definable active area by means of brakes.

Aus der DE-A 3 128 699, die einen Miniplotter zeigt und beschreibt, ist es grundsätzlich bekannt, diesen Miniplotter an einer Zeichenmaschine über dem Zeichenblatt beweglich festzulegen und dann mittels Fenstertechnik auch ein Zeichenblatt zu bearbeiten, welches größer ist, als der Arbeitsbereich des Miniplotters, der selbst nur eine DIN A4 Fläche abdeckt.From DE-A 3 128 699, which shows and describes a mini plotter, it is known in principle to fix this mini plotter movably on a drawing machine above the drawing sheet and then to edit a drawing sheet by means of window technology which is larger than the working area of the mini plotter , which itself only covers a DIN A4 area.

Ein Zeichenbrett 1, welches als solches bekannt ist und auch eine nicht dargestellte Zeichenmaschine aufweisen kann, die wegklappbar oder wegschwenkbar ist, besitzt hier mindestens an seiner oberen Längskante eine horizontal angeordnete Reihe von Stiften 2, die voneinander gleichmäßig beabstandet sind und deren Achsen sich senkrecht zur Erstreckungsebene des Zeichenbrettes 1 erstrecken.A drawing board 1, which is known as such and can also have a drawing machine, not shown, which can be folded away or swung away, has here, at least on its upper longitudinal edge, a horizontally arranged row of pins 2 which are evenly spaced from one another and whose axes are perpendicular to Extend plane of the drawing board 1.

Dieses Zeichenbrett 1 ist gemäß Figur 1 für maximale Blattformate DIN AO (1.189 mm x 841 mm ) vorgesehen und weist eine Breite von 1,5 m und eine Höhe von 1 m auf. Auf diesem Zeichenbrett 1 ist hier ein Zeichenblatt 3 des Formates DIN AO angeordnet. Dieses Zeichenblatt 3 wird nun in dreimal drei Matrix-Felder 4 eingeteilt, was hier durch strichpunktierte Feld-Begrenzungslinien 5 angedeutet ist.According to FIG. 1, this drawing board 1 is provided for maximum sheet formats DIN AO (1,189 mm x 841 mm) and has a width of 1.5 m and a height of 1 m. A drawing sheet 3 of the DIN AO format is arranged on this drawing board 1. This drawing sheet 3 is now divided into three times three matrix fields 4, which is indicated here by dash-dotted field boundary lines 5.

Gemäß Figur 2 ist das Zeichenbrett 1 für Zeichenformate DIN A1 (841 mm x 594 mm) vorgesehen und entsprechend kleiner. Auf diesem Zeichenbrett ist entsprechend ein Zeichenblatt DIN A1 angeordnet, welches analog zu Figur 1 in zweimal zwei Matrix-Felder 4 eingestellt ist.According to Figure 2, the drawing board 1 is provided for character formats DIN A1 (841 mm x 594 mm) and correspondingly smaller. A drawing sheet DIN A1 is correspondingly arranged on this drawing board, which is set in two matrix fields 4, as in FIG. 1, twice.

Diese Einteilung in Matrix-Felder 4 braucht auf dem Zeichenblatt 3 nicht durch Linien vorgenommen zu werden, wenngleich solche Hilfslinien die Übersicht erleichtern. Jedem dieser hier neun bzw. vier Matrix-Felder 4 kann ein und derselbe Plotter 6 zugeordnet werden, so daß für diesen einen Plotter 6 neun bzw. vier verschiedene Anordnungen möglich sein müssen. Jedes Matrix-Feld 4 erhält zuordnungsmäßig eine - hier - zweiziffrige Feldnummer 7, z.B. 11, 12,13,21,22,23,31, 32 und 33 bzw. 11, 12,21 und 22, wobei die erste Ziffer z.B. die "Zeile" der Matrix angibt, während die zweite Ziffer die "Spalte" der Matrix bezeichnet. Die Felder 4 können aber auch durchgehend nummeriert werden.This division into matrix fields 4 need not be made by lines on the drawing sheet 3, although such auxiliary lines make the overview easier. Each of these nine or four matrix fields 4 can be assigned one and the same plotter 6, so that nine or four different arrangements must be possible for this one plotter 6. Each matrix field 4 is assigned a - here - two-digit field number 7, e.g. 11, 12,13,21,22,23,31, 32 and 33 or 11, 12,21 and 22, the first digit e.g. indicates the "row" of the matrix, while the second digit indicates the "column" of the matrix. The fields 4 can also be numbered consecutively.

Der Plotter 6 kann nur jeweils ein Matrix-Feld in der Größe DIN A3 bearbeiten. Durch exakte Zuordnung des Plotters 6, auf die unten noch näher eingegangen wird, zu einem bestimmten Matrix-Feld 4, z.B. in Figur 1 zu dem Matrix-Feld 4 mit der Feldnummer "23" und in Figur 2 zu dem Matrix-Feld 4 mit der Feldnummer "22", kann der Computer intern ein ganzes Zeichenblatt der Größe DIN AO bzw. DIN A1 verwalten und es kann durch nacheinander erfolgende Verschiebung des Plotters 6 auch über das gesamte Blattformat gezeichnet werden, wenn dem Computer jeweils auch die Feldnummer 7 des Matrix-Feldes 4 angegeben wird, dem der Plotter 6 jeweils zugeordnet wird. Dies ist durch ein Software-Programm möglich, welches aufgrund der Zuordnung des bestimmten Matrix-Feldes 4 aus dem virtuellen Gesamtbild des Speichers des Computers nur das jeweilige virtuelle Bild des bestimmten Matrix-Feldes 4 auswählt.The plotter 6 can only process one matrix field in size A3. By exact assignment of the plotter 6, which will be discussed in more detail below, to a specific matrix field 4, e.g. in Figure 1 for the matrix field 4 with the field number "23" and in Figure 2 for the matrix field 4 with the field number "22", the computer can internally manage a whole drawing sheet of the size DIN AO or DIN A1 and it can be drawn over the entire sheet format by successively shifting the plotter 6 if the computer also specifies the field number 7 of the matrix field 4 to which the plotter 6 is assigned. This is possible by means of a software program which, on the basis of the assignment of the specific matrix field 4, only selects the respective virtual image of the specific matrix field 4 from the virtual overall image of the memory of the computer.

Die Zuordnung des Plotters 6 zu einem bestimmten Matrix-Feld 4 kann aufgrund zweier ähnlicher Ausbildungen des Zeichenbrettes erhalten werden, wobei die Ausführungsform gemäß Figur 2 nur möglich ist, wenn das Gesamtblatt in maximal zweimal zwei Felder 4 aufgeteilt wird, d.h., wenn z.B. bei Verwendung eines DIN A3-Plotters nur eine Zeichnung im Format DIN A1 auf einem entsprechend kleineren Zeichenbrett 1 erstellt werden soll.The assignment of the plotter 6 to a specific matrix field 4 can be obtained on the basis of two similar designs of the drawing board, the embodiment according to FIG. 2 being possible only if the entire sheet is divided into a maximum of two fields 4, i.e. if e.g. When using a DIN A3 plotter, only a drawing in DIN A1 format should be created on a correspondingly smaller drawing board 1.

Wie oben gesagt, zeigt Figur 1 die Verwendung eines DIN A3-Plotters 6 für die Erstellung einer DIN AO-Zeichnung, wobei eine Matrix mit neun Feldern 4 notwendig ist.As stated above, FIG. 1 shows the use of a DIN A3 plotter 6 for creating a DIN AO drawing, a matrix with nine fields 4 being necessary.

Da das Matrix-Feld 4 mit der Feldnummer "22" keine Seitenkante mit dem Zeichenformat des Blattes in Format DIN AO gemeinsam hat, der Plotter 6 also nicht - wie in Figur 2 - unmittelbar neben dem Zeichenblatt festgelegt werden kann, ist an einem solchen Plotter 6 eine Platte 8 befestigt, die möglichst durchsichtig sein sollte und hier aus einem Plexiglas bestehtSince the matrix field 4 with the field number "22" has no side edge in common with the character format of the sheet in DIN AO format, the plotter 6 cannot - as in FIG. 2 - be fixed directly next to the drawing sheet, is on such a plotter 6 a plate 8 attached, which should be as transparent as possible and here consists of a plexiglass

Diese Platte 8 ist hier etwas schmaler, als die größte Länge des Plotters 6, während die Länge der Platte 8 - in Figur 1 in der Vertikalen gesehen, also in Richtung der kürzeren Seitenkante des Matrix-Feldes 4 - geringfügig größer, als die doppelte Länge der kürzeren Seitenkante des Matrix-Feldes 4 ist.This plate 8 is here somewhat narrower than the greatest length of the plotter 6, while the length of the plate 8 - seen in the vertical in FIG. 1, that is in the direction of the shorter side edge of the matrix field 4 - is slightly larger than twice the length is the shorter side edge of the matrix field 4.

Diese Platte 8 weist nun hier, d.h., für ein Zeichen-Format DIN AO und einen Plotter des Formates DIN A3, drei vertikale Reihen von gleichmäßig voneinander beabstandeten Bohrungen 9 auf, wobei auch die drei Reihen gleichmäßig voneinander beabstandet sind. Der Abstand zwischen jeweils zwei Reihen von Bohrungen 9 ist maximal so groß, wie die kürzere Seitenkante eines Matrix-Feldes 4 lang ist. Entspricht die Größe des Matrix-Feldes 4 exakt dem Format DIN A3, also 420 mm x 297 mm, so beträgt dieser Abstand z.B. 280 mm.This plate 8 now has three vertical rows of bores 9 that are evenly spaced from one another, that is, for a DIN AO character format and a DIN A3 format plotter, the three rows also being evenly spaced from one another. The distance between two rows of bores 9 is at most as large as the shorter side edge of a matrix field 4 is long. If the size of the matrix field 4 corresponds exactly to the DIN A3 format, i.e. 420 mm x 297 mm, this distance is, for example, 280 mm.

Der Abstand zwischen den Bohrungen 9 einer Reihe ist so festzulegen, daß ein Vielfaches davon maximal der Länge der längeren Seitenkante des Matrix-Feldes entspricht, bei DIN A3 Format also z.B. der Abstand zwischen zwei Bohrungen 140 mm beträgt.The distance between the bores 9 of a row is to be determined such that a multiple thereof corresponds at most to the length of the longer side edge of the matrix field, i.e. in A3 format e.g. the distance between two holes is 140 mm.

Gemäß der Ausführungsform nach Figur 1 ist nun an der oberen Seitenkante des Zeichenbrettes 1 eine Leiste 10 angebracht, in der die Stifte 2 in einer Reihe angeordnet sind, wobei diese Reihe parallel zu dieser Seitenkante des Brettes verläuft. Der Abstand zwischen zwei benachbarten Stiften 2 entspricht exakt dem Abstand benachbarter Bohrungen der Platte 8.According to the embodiment according to FIG. 1, a strip 10 is now attached to the upper side edge of the drawing board 1, in which the pins 2 are arranged in a row, this row running parallel to this side edge of the board. The distance between two adjacent pins 2 corresponds exactly to the distance between adjacent holes in the plate 8.

Gemäß Figur 1 greifen jeweils drei Stifte 2 der Leiste 10 in drei Bohrungen 9 einer Reihe ein. Dadurch erhält der Plotter 6 gegenüber einem auf dem Zeichenbrett angebrachten Zeichenblatt 3 eine exakt definierte Position, der gemäß Figur 1 die Feldnummer "23" zuzuordnen ist.According to Figure 1 engage three pins 2 of the strip 10 in three holes 9 in a row. This gives the plotter 6 an exactly defined position relative to a drawing sheet 3 attached to the drawing board, to which the field number "23" can be assigned in accordance with FIG.

Löst man nun die Platte 8 von den Stiften 2 und verschiebt sie mitsamt dem Plotter 6 um hier drei Stifte nach links, so ist der Plotter 6 einer anderen exakt definierten Position, hier dem Matrix-Feld 4 mit der Feldnummer "22" zugeordnet. Dieses Matrix-Feld 4 hat nun Koordinaten, die im virtuellen Bild des Computers um den dreifachen Abstand benachbarter Stifte 2, also hier um 420 mm, in horizontaler X-Richtung kleiner sind, als die Koordinaten des Matrix-Feldes 4 mit der Feldnummer "23".If you now detach the plate 8 from the pens 2 and move them together with the plotter 6 by three pens to the left, the plotter 6 is assigned to another exactly defined position, here the matrix field 4 with the field number "22". This matrix field 4 now has coordinates that are smaller in the virtual image of the computer by three times the distance between adjacent pins 2, ie here by 420 mm, in the horizontal X direction than the coordinates of the matrix field 4 with the field number "23 ".

Entsprechend kann der Plotter 6 höher oder tiefer gehängt werden, wobei gemäß der Ausführungsform nach Figur 1 die vertikalen Y-Koordinaten jeweils um 280 mm verändert werden.Correspondingly, the plotter 6 can be hung higher or lower, the vertical Y coordinates being changed by 280 mm in each case according to the embodiment according to FIG.

Beim Auflegen des Plotters 6 auf das Zeichenblatt 3 in eine bestimmte Position muß also dem Computer nur mitgeteilt werden, welchem Matrix-Feld 4 der Plotter 6 zugeordnet wurde.When the plotter 6 is placed on the drawing sheet 3 in a certain position, the computer only has to be informed which matrix field 4 the plotter 6 has been assigned to.

Selbstverständlich können zwischen den einzelnen gezeichneten Reihen von Bohrungen 9 in der Platte 8 noch weitere dazu parallele Reihen von Bohrungen 9 vorgesehen sein. Wesentlich ist nur, daß dem Computer jeweils die exakte Lage des Plotters 6 durch Eingabe z.B. der Feldnummer 7 mitgeteilt wird.Of course, further parallel rows of holes 9 can be provided between the individual drawn rows of holes 9 in the plate 8. It is only essential that the exact position of the plotter 6 is given to the computer by input e.g. the field number 7 is communicated.

Der Plotter 6 weist nun ein Tastenfeld 12 auf. Mit diesem Tastenfeld 12 können Steuerbefehle für den Zeichenstift dem Plotter 6 eingegeben werden. Je nach Befehl wird dieser Befehl auch unmittelbar dem Computer über die Leitung 13 mitgeteilt. Über das Tastenfeld 12 läßt sich z.B. eingeben, daß der Zeichenstift ausgehend von einem vorher festgelegten Punkt einen Strich in einer bestimmten Richtung und mit einer bestimmten Länge ziehen soll.The plotter 6 now has a keypad 12. With this keypad 12, control commands for the drawing pen 6 can be entered. Depending on the command, this command is also communicated directly to the computer via line 13. The keypad 12 can e.g. Enter that the drawing pen should draw a line in a certain direction and with a certain length starting from a predetermined point.

Der Konstrukteur, der dieses Zeichenbrett 1 mit Plotter bedient, zeichnet nun nicht mehr mit Bleistift und Lineal, sondern er gibt über das Tastenfeld z.B. den Winkel ein, den er bisher an seiner Zeichenmaschine einstellte, worauf er dann über die Tasten des Tastenfeldes 12 eingibt, wie lang die Linie sein soll, die der Zeichenstift zeichnen soll. Kennt er die exakte Länge dieser Linie nicht, so kann er sich, wie bisher mit seinem Bleistift, an deren Ende "herantasten", d.h., er gibt erst einen großen Zeichenschritt und dann immer kleinere Zeichenschritte über das Tastenfeld ein, bis die Linie dort endet, wo sie gemäß der Vorstellung des Konstrukteurs enden soll. Es ist somit nicht notwendig, vorher die exakten Endkoordinaten einer Konstruktionslinie zu kennen, was beim "Konstruieren" seiten der Fall ist.The designer who operates this drawing board 1 with a plotter no longer draws with a pencil and ruler, but instead uses the keypad e.g. the angle that he has previously set on his drawing machine, whereupon he then uses the keys of the keypad 12 to enter how long the line should be that the drawing pen should draw. If he does not know the exact length of this line, he can "feel" at the end of it, as before with his pencil, ie he first enters a large drawing step and then increasingly smaller drawing steps using the keypad until the line ends there where it should end according to the designer's idea. It is therefore not necessary to know the exact end coordinates of a construction line beforehand, which is the case with "construction".

Gemäß einer besonderen Ausführungsform der Erfindung wird dabei der Zeichenstift in verschieden großen, abgestuften Schritten bewegt. Solche Schritte sind z.B. jeweils 100 mm, 10 mm, 1 mm und 0,1 mm. Soll der Zeichenstift entlang einer Linie um z.B. insgesamt 243,1 mm bewegt werden, so wird der Zeichenstift mittels einer "100 mm-Taste" zweimal um 100 mm bewegt, dann mittels einer "10 mm-Taste" viermal 10 mm, dann mittels einer "1 mm-Taste" dreimal um 1 mm und schlußendlich mittels einer "0,1 mm-Taste" noch um 0,1 mm. Daraus wird ersichtlich, daß der Konstrukteur sich dann, wenn ihm die Gesamtlänge der zu ziehenden Linie nicht bekannt ist, schrittweise an das Linienende heran-"tasten" kann.According to a special embodiment of the invention, the drawing pen is moved in differently sized, graduated steps. Such steps are e.g. 100 mm, 10 mm, 1 mm and 0.1 mm each. If you want the pen to move along a line e.g. a total of 243.1 mm are moved, the drawing pen is moved twice by 100 mm using a "100 mm button", then four times 10 mm using a "10 mm button", then three times using a "1 mm button" 1 mm and finally by a "0.1 mm button" by 0.1 mm. From this it can be seen that if the designer does not know the total length of the line to be drawn, he can gradually "touch" the end of the line.

Bei der Ausführungsform gemäß Figur 2 mit einem Zeichenblatt 3 des Formates DIN A1 und einem Plotter 6 des Formates DIN A3, also einer Einteilung in zweimal zwei Matrix-Felder 4, liegt der Plotter 6 immer mit zwei seiner Seitenkanten außerhalb des Formates des Zeichenblattes 3.In the embodiment according to FIG. 2 with a drawing sheet 3 of the format DIN A1 and a plotter 6 of the format DIN A3, i.e. a division into two matrix fields 4, the plotter 6 is always outside of the format of the drawing sheet 3 with two of its side edges.

Hier sind deshalb die Stifte 2, die den Plotter 6 gegenüber dem Zeichenbrett 1 ausrichten, neben dem Zeichenblatt 3 um dieses herum an allen seinen Seitenkanten angeordnet, während der Plotter 6 entweder an seinem rechteckigen Rahmen selbst Bohrungen 9 aufweist, wie in Figur 2 gezeigt, oder um diesen Rahmen noch eine umlaufende Leiste angebracht ist, in der die Bohrungen 9 angeordnet sind. Eine gesonderte Platte 8, wie bei der Ausführungsform gemäß Figur 1, ist hier also nicht erforderlich.Here, therefore, the pens 2, which align the plotter 6 with respect to the drawing board 1, are arranged next to the drawing sheet 3 around it on all of its side edges, while the plotter 6 itself has holes 9 on its rectangular frame, as shown in FIG. 2, or a circumferential strip in which the bores 9 are arranged is also attached to this frame. A separate plate 8, as in the embodiment according to FIG. 1, is therefore not necessary here.

Die Abstände zwischen benachbarten Bohrungen 9 und Stiften 2 sind hier analog der Ausführungsform gemäß Figur 1 zu wählen.The distances between adjacent bores 9 and pins 2 are to be selected here analogously to the embodiment according to FIG. 1.

Hier kann der Plotter 6 dann, wenn nur zweimal zwei Matrix-Felder 4 gewünscht sind, an jeweils zwei seiner Seitenkanten gegenüber dem Zeichenbrett 1 festgelegt werden.Here, if only two matrix fields 4 are desired, the plotter 6 can be fixed on two of its side edges opposite the drawing board 1.

Ist bei der Ausführungsform gemäß Figur 2 eine umlaufende Leiste um den Plotter 6 vorgesehen, so sollte diese Leiste auch aus einem durchsichtigen Material, z.B. aus einem Plexiglas bestehen.If a circumferential bar is provided around the plotter 6 in the embodiment according to FIG. 2, this bar should also be made of a transparent material, e.g. consist of a plexiglass.

Der Rand des Plotters 6 sollte möglichst schmal sein, da die Teile der Zeichnung, die sich jeweils unter diesem Rand befinden, von dem Konstrukteur nicht gesehen werden können. Je schmaler dieser Rand ausgebildet ist, desto besser ist der Überblick über die Gesamtheit der Zeichnung.The edge of the plotter 6 should be as narrow as possible, since the parts of the drawing that are located below this edge cannot be seen by the designer. The narrower this border is, the better the overview of the entire drawing.

Die Stifte 2, die an dem Zeichenbrett 1 direkt (Figur 2) oder indirekt (Figur 1) festgelegt sind, bestehen hier aus verschleißfestem Metall. Auch kann die Leiste 10 aus Metall sein, um eine ausreichende Stabilität derselben und bleibende Ausrichtung der Stifte 2 auch über lange Zeit zu gewährleisten.The pens 2, which are attached to the drawing board 1 directly (FIG. 2) or indirectly (FIG. 1), are made of wear-resistant metal. The strip 10 can also be made of metal in order to ensure sufficient stability thereof and permanent alignment of the pins 2 even over a long period of time.

Die oben beschriebenen "Bohrungen" 2 sind bei einer besseren Ausführungsform Bohrungen in einer Plexiglas-Platte 8 oder umlaufenden Plexiglas-Leiste, in die Metallbuchsen eingesetzt sind. Der Innendurchmesser dieser Metallbuchsen ist auf den Außendurchmesser der Stifte 2 so abgestimmt, daß ein Paßsitz vorliegt. Dadurch wird die exakte Positionierung des Plotters 6 gegenüber den Stiften 2 und somit gegenüber dem Zeichenbrett 1 gewährleistet. Ist nach längerem Gebrauch des Zeichenbrettes 1 mit dem Plotter 6 das Spiel zwischen den Bohrungen 9 und den Stiften 2 zu groß, so können die Metallbuchsen gegen neue Metallbuchsen ausgewechselt werden. Auch ist es möglich, die Stifte 2 austauschbar auszubilden, um bei Verschleiß der Stifte 2 auch brettseitig für exakten Sitz zu sorgen.In a better embodiment, the “bores” 2 described above are bores in a plexiglass plate 8 or circumferential plexiglass strip into which metal bushings are inserted. The inner diameter of these metal bushings is matched to the outer diameter of the pins 2 so that there is a snug fit. This ensures the exact positioning of the plotter 6 relative to the pens 2 and thus relative to the drawing board 1. If after a long use of the drawing board 1 with the plotter 6 the play between the holes 9 and the pins 2 is too great, the metal bushings can be exchanged for new metal bushings. It is also possible to design the pins 2 to be interchangeable in order to ensure an exact fit when the pins 2 are worn.

Gemäß einer nicht dargestellten, der in Figur 1 dargestellten ähnlichen Ausführungsform ist anstelle der Platte 8 ein Rahmen aus mehreren Leisten vorgesehen, die jeweils parallel zu den Seitenkanten des Plotters liegen.According to an embodiment, not shown, which is similar to that shown in FIG. 1, instead of the plate 8, a frame made of several strips is provided, each of which is parallel to the side edges of the plotter.

Horizontale Leisten weisen dabei jeweils eine Reihe von Bohrungen 9 auf, während die dazu senkrechten Leisten eine Verbindung der Bohrungen 9 aufweisenden Leisten mit dem Plotter 6 gewährleisten.Horizontal strips each have a number of bores 9, while the vertical strips ensure a connection of the bores 9 with the plotter 6.

Die Einteilung der Matrix-Felder 4 kann auch anders erfolgen, als oben beschrieben, insbesondere können die Matrix-Felder 4 wesentlich kleiner sein, als oben beschrieben.The matrix fields 4 can also be classified differently than described above, in particular the matrix fields 4 can be significantly smaller than described above.

Ein oben anhand der Figur 1 beschriebenes Matrix-Feld 4, welches dort 420 mm x 280 mm aufweist, könnte nochmals in sechs Felder unterteilt sein, die quadratisch sind und eine Seitenlänge von 140 mm aufweisen. Entsprechend müßte dann die Anzahl der Feldnummern 7 von neun auf 42 vergrößert werden. Dies ist insbesondere dann vorteilhaft, wenn der Konstrukteur eine Einzelheit der Zeichnung eigentlich dort zeichnen will, wo sich zwei Felder der "Neuner"-Einteilung berühren. Es ist dann möglich, den Plotter 6 exakt so auszurichten und zu halten, daß dem Konstrukteur wieder ein volles Arbeits-Feld 4 im Format DIN A3 zur Verfügung steht.A matrix field 4 described above with reference to FIG. 1, which has 420 mm × 280 mm there, could again be divided into six fields, which are square and have a side length of 140 mm. Accordingly, the number of field numbers 7 would have to be increased from nine to 42. This is particularly advantageous if the designer actually wants to draw a detail of the drawing where two fields of the "nine" division meet. It is then possible to align and hold the plotter 6 exactly in such a way that the designer has again a full work area 4 in DIN A3 format.

Das gesamte Zeichenblatt kann auch in Matrix-Felder 4 eingeteilt werden, die horizontal und/oder vertikal jeweils um exakt 100 mm voneinander verschoben sind, wenngleich dann Vielfache davon nicht mehr mit den DIN-Formaten übereinstimmen. Es ergibt sich dann aber für den Konstrukteur die Möglichkeit, sehr einfach die Koordinaten auch bei Verschiebung des Plotters nachzuvollziehen.The entire drawing sheet can also be divided into matrix fields 4, which are horizontally and / or vertically displaced by exactly 100 mm from each other, although multiples of them then no longer match the DIN formats. However, the designer then has the opportunity to easily follow the coordinates even when the plotter is moved.

Der Plotter 6 kann aber auch anstelle der Zeichenlineale an einer bekannten Zeichenmaschine festgelegt sein, wobei z.B. an dieser Mittel, wie Bohrungen und Stifte, vorgesehen sind, um die Zeichenmaschine und damit den Plotter jeweils in einer bestimmten Stellung zu arretieren. Solche' Zeichenmaschinen müssen allerdings stabiler ausgeführt sein, als allgemein üblich, da der Plotter 6 ein viel größeres Gewicht aufweist, als die sonst verwendeten Lineale. Bei einer sogenannten Parallelogramm-Zeichenmaschine sind dazu z.B. in je einer Strebe eines Paares von Parallelführungen Bohrungen vorgesehen, wobei für jedes gewünschte Matrix-Feld 4 jeweils eine Bohrung der einen Führungsstrebe mit einer Bohrung der anderen Führungsstrebe zur Deckung gebracht und mittels eines Stiftes od. dgl. gegeneinander gesichert werden.The plotter 6 can also be fixed to a known drawing machine instead of the drawing rulers, e.g. on this means, such as holes and pens, are provided in order to lock the drawing machine and thus the plotter in a particular position. Such 'drawing machines must, however, be made more stable than is customary, since the plotter 6 has a much greater weight than the rulers otherwise used. In a so-called parallelogram drawing machine, e.g. bores are provided in each strut of a pair of parallel guides, a bore of the one guide strut being made to coincide with a bore of the other guide strut for each desired matrix field 4 and secured against one another by means of a pin or the like.

Bekannt sind weiterhin Zeichenmaschinen mit Geradführung, bei denen der Zeichenkopf mit den Zeichenlinealen entlang einer vertikalen Schiene vertikal verschiebbar ist, wobei diese vertikale Schiene selbst wieder an einer oder zwei horizontalen Schiene(n) horizontal verschiebbar ist. In diesen Schienen können bei dieser bekannten Zeichenmaschine noch Meßwertgeber zur Ermittlung der Lage der Zeichenlineale vorgesehen sein.Drawing machines with straight guidance are also known, in which the drawing head with the drawing rulers can be displaced vertically along a vertical rail, this vertical rail itself being horizontally displaceable on one or two horizontal rails. In this known drawing machine, sensors can also be provided in these rails for determining the position of the drawing rulers.

Anstelle des Zeichenkopfes wird nun ein Plotter an der vertikalen Schiene der Zeichenmaschine insbesondere drehfest festgelegt. Durch die Meßwertgeber läßt sich nun jeweils die Lage des Plotters auf dem Zeichenbrett bestimmen und die dabei erhaltenen Werte werden unmittelbar dem Computer übermittelt.Instead of the drawing head, a plotter is now fixed on the vertical rail of the drawing machine, in particular in a rotationally fixed manner. The position of the plotter on the drawing board can now be determined by the transducers and the values obtained are immediately transmitted to the computer.

Insbesondere hierbei kann der Plotter z.B. mit Schrittschaltmotoren motorisch über das Zeichenbrett bewegt werden. Auch hierbei empfiehlt es sich, das Zeichenbrett in bestimmte Felder einzuteilen, wobei z.B. der Plotter entlang der vertikalen Schiene und die vertikale Schiene entlang der horizontalen Schiene nur in 100 mm-Schritten bewegt wird. Dazu sind z.B. eine Anzahl von Endschaltern sowohl in der vertikalen, als auch in der horizontalen Schiene vorgesehen. Dabei wird der Plotter durch Betätigen eines weiteren Schalters bewegt, bis er am Zeichenbrett einen bestimmten, dem gewünschten Matrix-Feld 4 zugeordneten Endschalter erreicht hat.In particular, the plotter can e.g. can be moved by motor over the drawing board with stepper motors. It is also advisable to divide the drawing board into certain fields, e.g. the plotter is only moved in 100 mm steps along the vertical rail and the vertical rail along the horizontal rail. For this, e.g. a number of limit switches are provided in both the vertical and horizontal rails. The plotter is moved by actuating another switch until it has reached a certain limit switch assigned to the desired matrix field 4 on the drawing board.

Andererseits kann durch die Meßwertgeber sehr einfach und exakt festgestellt werden, in welcher Lage sich der Plotter auf dem Zeichenbrett befindet, weshalb das Zeichenbrett in eine Vielzahl von beliebigen Feldern 4 eingeteilt werden könnte.On the other hand, it can be determined very simply and precisely by the measuring value transmitter in which position the plotter is on the drawing board, which is why the drawing board could be divided into a number of arbitrary fields 4.

Bei ausreichend stabiler Ausbildung dieser Art von Zeichenmaschine sind keine weiteren Mittel zum Halten des Plotters mehr notwendig.With a sufficiently stable design of this type of drawing machine, no further means for holding the plotter are necessary.

Figur 3 zeigt ein Zeichenbrett 1, an dessen vertikalen Seitenkanten Leisten 10 mit Bohrungen 2' angeordnet sind, gegenüber denen eine horizontale Leiste 14 mit Bohrungen 2 festlegbar ist. Diese Leisten 10 und 14 können die Schienen einer Zeichenmaschine sein. An dieser Leiste 14 ist gegenüber den Bohrungen 2 der Plotter 6 festlegbar. Hier weist auch der Plotter 6 Bohrungen auf. Durch entsprechende Bohrungen wird jeweils ein Stift 15 gesteckt, um den Plotter 6 gegenüber dem Zeichenbrett 1 zu halten. Es wurde hier ein Bohrungsabstand von jeweils 200 mm gewählt, so daß sich hier insgesamt 20 sich überschneidende Matrix-Felder 4 ergeben.FIG. 3 shows a drawing board 1, on the vertical side edges of which strips 10 with bores 2 'are arranged, against which a horizontal strip 14 with bores 2 can be fixed. These strips 10 and 14 can be the rails of a drawing machine. On this bar 14, the plotter 6 can be fixed relative to the bores 2. The plotter also has 6 holes here. A pin 15 is inserted through appropriate holes in order to hold the plotter 6 relative to the drawing board 1. A hole spacing of 200 mm was chosen here, so that there are a total of 20 overlapping matrix fields 4.

Die Ausführungsform gemäß Figur 4 benutzt einen rechteckigen Rahmen 16, der gegenüber dem Zeichenbrett 1 in der Horizontalen verschieb- und festlegbar ist, während der Plotter 6 in diesem Rahmen 16 vertikal verschieb- und festlegbar ist. Hier beträgt der Lochabstand in der Horizontalen 200 mm, während der Lochabstand in der Vertikalen 100 mm beträgt. Dabei wird dem Format des Plotters 6 Rechnung getragen, der in der Horizontalen größer ist, als in der Vertikalen.The embodiment according to FIG. 4 uses a rectangular frame 16 which is horizontally displaceable and fixable with respect to the drawing board 1, while the plotter 6 can be vertically displaced and fixed in this frame 16. Here the hole spacing in the horizontal is 200 mm, while the hole spacing in the vertical is 100 mm is. The format of the plotter 6 is taken into account, which is larger in the horizontal than in the vertical.
