Description
Kopiermaschine mit Storchschnabelgestänge Bei der im Hauptpatent 698 5..2 beschriebenen Kopiermaschine ist es erforderlich, daß die Achsen der Gelenkverbindungen zwischen Schreibpunkt und Werkzeugträger bzw. zwischen Fahrpunkt und Kopierstift zu der waagerechten Hauptachse des Storchschnabelgestänges stets parallel sind, weil sonst beim Neigen des letzteren Klemmungen und Fehler in der Höhenlage auftreten. Wenn das Werkzeu-lager in einem parallel zu sich geführten Balken sitzt, läßt sich diese Bedingung für das Schreibpunktgelenk leicht durch Verbindung desselben mit dem Balken erfüllen, aber bei dem Fahrpunktgelenk ist dies nicht möglich. Man könnte: zwar, wie dies bei Kopiermaschinen mit Axialsteuerung von Taster und Werkzeug durch einen Hebel schon geschieht, alle drei Gelenke durch einen Führungsstab verbinden, aber dieser muß in seiner Länge der größten Entfernung des Fahrpunktes von der Storchschnabelhauptachse entsprechen und ragt deshalb bei allen anderen Stellungen des Storchschnabelgestänges um einen mehr oder weniger großen Betrag über den Fahrpunkt oder die Hauptachse hinaus.Copier with cranesbill rods In the copier machine described in the main patent 698 5..2, it is necessary that the axes of the articulated connections between the writing point and the tool carrier or between the driving point and the copying pen are always parallel to the main horizontal axis of the cranesbill rods, because otherwise clamps when the latter is inclined and errors in altitude occur. If the tool store is seated in a beam that is parallel to itself, this condition for the writing point joint can easily be met by connecting it to the beam, but this is not possible with the driving point joint. It is possible, as is already the case with copier machines with axial control of buttons and tools by means of a lever, to connect all three joints with a guide rod, but this must correspond in length to the greatest distance of the travel point from the main axis of the cranesbill and therefore protrudes from all others Positions of the cranesbill rod by a more or less large amount beyond the driving point or the main axis.
Diese Schwierigkeiten «-erden erfindungsgemäß dadurch umgangen, daß die Ausrichtung der Gelenkachse (n) von vornherein überflüssig gemacht wird, indem an der oder den betreffenden Stellen Kreuz- oder Kugelgelenke eingebaut werden. In der "Zeichnung ist die Anwendung des Erfindungsgedankens bei dein Ausführungsbeispiel des Hauptpatents -schematisch in einer Seitenansicht gezeigt. Da hei dieser Maschine das mit dein Schreibpunkt i; des Storchschnabelgestänges verbundene Gleitstück 18 auf dein parallel zu sich geführten Balken 12 bzw. der darauf befestigten Schiene 16 sitzt, ist die Achse dieses Gelenkes ohnehin stets parallel zur Hauptachse i des Storchschnabelgestänges. Dagegen ist die Achse der Gelenkverbindung zwischen dein Fahrpunkt I9 und dem Kopierstift ?o nicht gegen Verdrehen gesichert; sie wird daher durch ein Kreuzgelenk 33 ersetzt. Selbstverständlich kann statt dessen bei geringer Beanspruchung auch ein Kugelgelenk verwendet werden. Das Schreibpunktgelenk 17 ist in gleicher `'eise zu ändern, wenn das Werkzeuglager 1 ,3, 14. ähnlich wie der Kopierstift 2o an frei beweglichen Führungsarmen aufgehängt ist.According to the invention, these difficulties are circumvented in that the alignment of the joint axis (s) is made superfluous from the outset by installing universal joints or ball joints at the point or points concerned. In the "drawing, the application of the inventive concept to your embodiment of the main patent is shown schematically in a side view. In this machine the sliding piece 18 connected to your writing point i; 16, the axis of this joint is always parallel to the main axis i of the cranesbill rods anyway. In contrast, the axis of the joint connection between your driving point I9 and the copying pen? O is not secured against rotation; it is therefore replaced by a universal joint 33. Of course, instead A ball-and-socket joint can also be used if the load is low. The writing point joint 17 is to be changed in the same way if the tool store 1, 3, 14 is suspended on freely movable guide arms similar to the copying pen 2o.
