Es ist allgemein bekannt, zur Überprüfung der registergenauen Anlage von Druckplatten einen schließbaren Stromkreis zu verwenden, der durch das Eingreifen von Registerbolzen der Spannschiene in Maßkerben der Druckplatte erfolgt.It is generally known for checking the register-accurate installation of Pressure plates to use a closable circuit that is controlled by the Intervention of register bolts of the clamping rail in the notches of the pressure plate he follows.
Durch die EP 0 551 976 B1 ist es beispielsweise bekannt, elektrisch leitende Anschläge für eine Druckplatte vorzusehen, wobei bei genauer Anlage der Druckplatte an den Anschlägen mittels der elektrisch leitenden Druckplatte ein Stromkreis geschlossen wird und auf diese Weise eine genaue Positionierung der Druckplatte angezeigt wird.From EP 0 551 976 B1 it is known, for example, to be electrically conductive To provide stops for a printing plate, the precise Pressure plate at the stops by means of the electrically conductive pressure plate Circuit is closed and in this way accurate positioning the pressure plate is displayed.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Erfassung einer Druckplattenlage zu schaffen, die ohne elektrisch leitende Anschläge arbeitet.The invention has for its object a device for detecting a To create pressure plate layer that works without electrically conductive stops.
Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.The object is achieved by the features of claim 1 solved.
In vorteilhafter Weise werden als Druckplattenerfassungsmittel mechanische Spannungssensoren eingesetzt. Mechanical plates are advantageously used as pressure plate detection means Voltage sensors used.
Jedem Registermittel, welches mit einer Kante der Druckplatte korrespondiert, ist mindestens ein mechanischer Spannnungssensor zugeordnet. Die mechanischen Spannungssensoren sind im Bereich von Kraftwirkungslinien angeordnet, die entstehen, wenn ein Registermittel eine mechanische Verformung, bzw. Auslenkung erfährt. Vorzugsweise werden die mechanischen Spannungssensoren in der Nähe der Registermittel, z. B. Anschläge, angeordnet, da dort die eingebrachten Spannungen am größten sind und somit am genauesten erfaßbar sind.Any register means that corresponds to an edge of the printing plate at least one mechanical tension sensor is assigned. The mechanical tension sensors are in the range of force action lines arranged, which arise when a register means a mechanical Deformation or deflection experiences. Preferably the mechanical Voltage sensors near the register means, e.g. B. attacks, arranged, because there the tensions are greatest and thus are most precisely detectable.
Besonders vorteilhaft ist eine Anordnung der mechanischen Spannungssensoren im Grund der Klemmleiste, in welcher die Registermittel angeordnet sind.An arrangement of the mechanical ones is particularly advantageous Voltage sensors in the bottom of the terminal block, in which the register means are arranged.
In vorteilhafter Weiterbildung ist es vorgesehen den Bereich um die Registermittel herum durch Durchbrüche oder Ausnehmungen zu schwächen, damit die Registermittel schon bei Einwirkung kleinster Kräfte ausgelenkt werden. Die mechanischen Spannungssensoren können hierbei auf Stegen angeordnet werden, die zwischen den Durchbrüchen vorgesehen sind.In an advantageous development, the area around the Weakening register means around through openings or recesses, so that the register means are deflected even under the action of the smallest forces become. The mechanical tension sensors can be on ridges are arranged, which are provided between the openings.
In erfindungsgemäßer Ausführung bestehen die mechanische Spannungssensoren aus piezokeramischen Körperschallsensoren. Piezokeramische Körperschallsensoren haben den Vorteil, daß sie in erster Linie auf dynamische Veränderungen oder Zustände wie Platteneinführung reagieren. Langsame Spannungsänderungen wie Maschinenalterung, Verspannung mechanischer Bauteile usw. werden dabei nicht erfaßt.In the embodiment according to the invention, there are mechanical ones Voltage sensors made of piezoceramic structure-borne noise sensors. Piezo-ceramic structure-borne noise sensors have the advantage that they are first Line on dynamic changes or conditions such as plate insertion react.

29 werden vorzugsweise so angebracht, daß diese vom Registermittel
(Anschlag) 21, 22 aus gesehen, auf der der Druckplatte 16

Daten und Energie ist es vorgesehen, eine Energieversorgungsquelle 42 direkt
an der Spannschiene 20 anzuordnen und diese mit der Elektronik 31 zu
verbinden. Die Energieversorgungsquelle 42 kann hierbei beispielsweise eine
Batterie, ein Akku oder ein Dynamo in Verbindung mit einem aufladbaren Akku
sein, bei dem eine Energiespeisung aus der Rotation des Plattenzylinders 11;

die Anschläge 21, 22 mit Durchbrüchen 37, 38 zu versehen, und die
Sensoren 27, 28, 29 auf Stegen 39 bis 41 anzuordnen. Hierdurch ergeben sich
bei Belastung der Anschläge 21, 22 durch die Druckplatte 16 größere
mechanische Spannungen in den Stegen 39, 41 und somit ein stärkeres :
