'■■ X-Y-Positioniereiiirichtung zur Qualitätskontrolle im Offsetdruck '■■ XY positioning device for quality control in offset printing
Die Erfindung betrifft eine Vorrichtung zur Farbmessung für den Offsetdruck, wobei eine Farbmeßeinrichtung mittels eines Positioniersysteins über jeden Punkt der auszumessenden Vorlage bewegt werden kann.The invention relates to a device for color measurement for offset printing, whereby a color measuring device can be moved by means of a positioning system over any point of the original to be measured.
Ziel ist es, densitorhetrische und spektrale Farbwerte einer Vorlage sicherheitsgerecht und optimal bezüglich Platzbedarf und Bewegungsfreiheit zu messen, um diese dann mit Hilfe eines Rechnersystem auszuwerten, ggf. mit Sollvorgaben zu vergleichen und zur Korrektur der Farbdosierung zu nutzen.The aim is to measure the densitometry and spectral color values of a template in a safe and optimal way with regard to space requirements and freedom of movement, in order to then evaluate them with the help of a computer system, if necessary, compare them with target specifications and use them to correct the color dosage.
Es sind X- oder X- und Y-Positiomersysteme bekannt, die mit Densitometern und/oder Tristimulusmeßköpfen und/oder Spektralfotometern und/oder CCD-Kaineras bestückt werden, die vorgegebene Meßpunkte der Meßbogen (1) anfahren und ausmessen.X or X and Y positometer systems are known which are equipped with densitometers and/or tristimulus measuring heads and/or spectrophotometers and/or CCD cameras which move to and measure predetermined measuring points on the measuring arc (1).
Ein Problem stellen bei all diesen Meßsystemen die Quetsch- und Scherstellen an den bewegten Teilen dar, die zum Schutz von Personen und Gegenständen abzusichern sind.A problem with all these measuring systems is the crushing and shearing points on the moving parts, which must be secured to protect people and objects.
Schon beim flachen Auflegen der Hand auf die Meßfläche (2) können bei Spalthöhen > 6mm infolge der Keilwirkung zwischen Meßfläche, Hand und bewegten Teilen extrem hohe Kräfte auftreten. Herkömmliche Mittel, wie z.B. Drehmomentenbegrenzung wirken der Effektivität des Gesamtmeßsystems entgegen, und Sicherheitsabfragen mittels Software, z.B. Schleppfehlerkontrolle, sind als alleinige Personenschutzsichherungen unzulässig.Even if the hand is placed flat on the measuring surface (2), extremely high forces can occur at gap heights of > 6 mm due to the wedge effect between the measuring surface, the hand and the moving parts. Conventional means, such as torque limitation, counteract the effectiveness of the entire measuring system, and safety queries using software, e.g. tracking error control, are not permitted as the sole means of personal protection.
Daher wird vorgeschlagen, an den, mittels Linarführung bewegten Teilen, eine Sicherheitseinrichtung (3) anzubringen, wobei die Annäherung an beliebiger Stelle und von beliebiger Richtung den sofortigen Abbruch der Bewegung zur Folge hat. Dies kann z. B. mittels, sich im Innern der Sicherheitskontaktleiste befindlichen, leitenden, sich.gegenüberliegenden Kontaktstreifen, oder mittels berührungslos wirkender Lichtschranken realisiert werden. Dabei sind alle Sicherheitseinrichtungen so in Reihe geschaltet, daß sie ein selbstsicherades System darstellen.It is therefore proposed to attach a safety device (3) to the parts that are moved by means of linear guides, whereby approaching it at any point and from any direction results in the immediate termination of the movement. This can be achieved, for example, by means of conductive contact strips located inside the safety contact strip, which are opposite one another, or by means of contactless light barriers. All safety devices are connected in series in such a way that they form a self-safe system.
Ein weiteres Problem bei den Qualitätsfarbmeßsystemen im Bogenoffset stellt der Platzbedarf der Meßsysteme dar. Bekannt sind Meßtische, die zusätzlich zum Plattenscanner und Abstimmtisch an Bogendruckmaschinen aufgestellt werden. Um dem Nachteil des erhöhten Platzbedarfes zu begegnen wurden im Gebrauchsmuster G 93 02 173.9 Systeme vorgeschlagen, die die Messung der bedruckten Bogen auf dem Abstimmtisch erlauben.Another problem with quality color measurement systems in sheet-fed offset is the space required by the measurement systems. Measuring tables are known that are set up in addition to the plate scanner and matching table on sheet-fed printing machines. In order to counteract the disadvantage of the increased space requirement, systems were proposed in utility model G 93 02 173.9 that allow the measurement of the printed sheets on the matching table.
Als Nachteil ist dabei zu nennen, daß der Drucker in der Zeit der Messung durch das System behindert wird. Außerdem muß er Gewohnheiten auf dem Abstimmtisch, z.B. das zusätzliche Unterlegen von Druckbogen an den beiden Seitekanten, sowie der Vorder- und Hinterkante, aufgeben. Aufgabe der Erfindung ist es, ein Meßsystem zu schaffen, das mit dem geringen Platzbedarf an der Druckmaschine auskommt, und dem Drucker seinen Freiraum auf dem Abstimmtisch läßt.One disadvantage is that the printer is hindered by the system during the measurement. In addition, he must give up habits on the calibration table, e.g. additional support of the printed sheet on the two side edges, as well as the front and rear edges. The aim of the invention is to create a measuring system that manages with the small space required on the printing machine and leaves the printer free space on the calibration table.
Außerdem ist das Meßsystem so zu gestalten, daß der Drucker den Bogen zum Ausmessen bequem, und ohne Behinderung des Bewegungsbereiches einlegen kann.In addition, the measuring system must be designed in such a way that the printer can insert the sheet for measurement comfortably and without hindering the range of motion.
Alle bekannten X-Y-Positioniersysteme zur Qualitätskontrolle im Offsetdruck bestehen aus einer, die Vorlage überspannenden Brücke als Lineareinheit, an deren Schlitten der Sensor angeordnet ist, wobei die Enden der Brücke wiederum auf parallel beweglichen Schlitten zweier sich gegenüberliegender Linieareinheiten fixiere sind. In jedem Fall werden aber, auch wenn die Homeposition der Sensoren außerhalb des Bogenbereiches liegt, drei Seiten des Meßsystems mit Linearführungen blockiert, die den Drucker beim AuflegenAll known X-Y positioning systems for quality control in offset printing consist of a bridge spanning the template as a linear unit, on whose carriage the sensor is arranged, with the ends of the bridge in turn being fixed on parallel moving carriages of two opposing linear units. In any case, even if the home position of the sensors is outside the sheet area, three sides of the measuring system are blocked with linear guides that guide the printer when placing the template.

der Bogen auf die Meßfläche behindern.the arc on the measuring surface.
Erfindungsgemäß werden die o.a. Probleme dadurch gelöst, daß das Meßsystem als flache Konstruktion mit einem Freiann ausgebildet wird, wobei die Anordnimg des gesamten Meßsystems mittels Galgenkonstniktion über einem beliebigen, im Bereich der Auslage der Bogendruckmaschine befindlichen, Stapel erfolgt.According to the invention, the above-mentioned problems are solved by designing the measuring system as a flat construction with a free arm, whereby the arrangement of the entire measuring system is carried out by means of a gallows construction above any stack located in the delivery area of the sheet-fed printing press.
Der, an allen Maschinen in der Druckerei vorhandene und bisher ungenutze Platz über diversen Stapeln (z.B.The previously unused space available on all machines in the printing shop above various stacks (e.g.
Stapel für bedruckte, abholbereite Bogen der 1. oder 2. Wahl oder für Makulaturbogen) wird damit durch ein, im folgenden Ausführungsbeispiel beschriebenes Meßsystem genutzt.Stack for printed, ready-to-collect sheets of the 1st or 2nd choice or for waste sheets) is used by a measuring system described in the following example.

Das Positioniersystem der Meßeinrichtung besteht aus einer, in X-Richtung beweglichen Linearführung (4) und der quer dazu in Y-Richtung beweglichen Linearführung (5). Dabei wird die, den Bogen überspannende Brückenkonstruktion durch eine Freiannkonstruktion ersetzt, wobei die, die Freiarrnlinearführung (5) mit Sensorik (6) tragende, Linearführung (4)bezüglich Führungslänge und -breite größer dimensioniert ist, um die höhere Momentenbelastung zu kompensieren.The positioning system of the measuring device consists of a linear guide (4) that can be moved in the X direction and the linear guide (5) that can be moved perpendicular to it in the Y direction. The bridge construction that spans the arch is replaced by a free-arm construction, whereby the linear guide (4) that supports the free-arm linear guide (5) with sensors (6) is dimensioned larger in terms of guide length and width in order to compensate for the higher moment load.
Der Antrieb der Linearführungen erfolgt mittels DC-Motoren über Zahnriemen und kugelgelagerte Spindeln. Zum besseren Auflegen der Bogens auf die Meßfläche (2) bildet diese mit der Linearführung (4) eine Ebene, wobei der Raum unter der Mefläche für eine stabile, mit der Linearführung (4) verbundene, Unterbaukonstruktion (7), z.B. in Form von Längs- und Querträger genutzt wird, in der gleichzeitig notwendige Steuer-, Sicherheits- und Bedienelemente, z.B. Tasten (8) oder Trackballfach (9), elektrische und pneumatische Leitungen, Einrichtungen zur Bogenfixierung (10) u.a. untergebracht sind. Die Unterbaukonstruktion wird auf zwei galgenfbrrnigen Trägern fixiert, wobei die Galgenträger (11) über einem beliebigen, im Bereich der Bogenauslage befindlichen, Stapel (12) angeordnet sindThe linear guides are driven by DC motors via toothed belts and ball-bearing spindles. To better place the sheet on the measuring surface (2), this forms a plane with the linear guide (4), whereby the space under the measuring surface is used for a stable substructure (7) connected to the linear guide (4), e.g. in the form of longitudinal and transverse supports, in which the necessary control, safety and operating elements, e.g. buttons (8) or trackball compartment (9), electrical and pneumatic lines, devices for sheet fixation (10) and others are housed. The substructure is fixed on two gallows-shaped supports, whereby the gallows supports (11) are arranged above any stack (12) located in the area of the sheet delivery
Am einem der Galgenträger (11) befindet sich ein schwenkbarer Monitor (13) mit Tastatur (14). Der Rechner (15) und die Steuereinheit für die DC-Motoren (16) werden in mittelbarer Nähe zum Meßsystem, z.B. unter der Galerie (17) der Druckmaschine im Bereich der Auslage untergebracht, wobei diese Einheiten über Leitungen mitdem Meßtisch verbunden sind.A swiveling monitor (13) with keyboard (14) is located on one of the boom supports (11). The computer (15) and the control unit for the DC motors (16) are housed in close proximity to the measuring system, e.g. under the gallery (17) of the printing machine in the delivery area, with these units being connected to the measuring table via cables.
