Description
Parallel zur Führung 11 des Meßkopfes sind über die Tischbreite verteilt mehrere Bogenanschlãge 12 vorgeseben, an die eini auf den Abstimmtisch 10 aufgelegter Bogen angelegt wird. Ebenfalls parallel Zur Führung 11 verlãuR eine Hauptsaugluiste 13, die, was die Fig2 zeigt, als Vierkantprofil ausgeführt und mit ihrem Hohlraum 14 über ein Ventil an Unterdrück angeschlossen werden kann. In ihrer in der Höhe der Eben des Absinmtisches 111 liegenden Oberseite sind zahlreiche Bohrungen 15 angebracht, durch die ein aufliegender Bogen gestgesaugt werden kann Neben der Hauptsaugleiste 13 in Richtung zur Fläche des Abstimmmtisches 10 befindet sich ein Kanal 16, der im bereich seiner Enden von Führungsstangen 17 überspannt wird. Auf diesen Führungsstangen 17 sind festigkelmmbare Gleitstücke 18 geführt, zwischen denen sich, im Kanal 16 liegend, eine Hilfssaugleiste 19 erstreckt, deren Hohlraum 20 (siehe Fig. 2) eberEalls huber ein weiteres Ventil an eine Unterdruckquelle angeschlossen ist. Die Oberseite der Hilfssausgleiste 19 befindet sich in der Ebene des Abstimuntisches X und ist von BohrEmgen 21 durchsetzt, mit deren Hilfe ein darüberliegender Bogen festgesaugt werden kann, wenn über das zu steuernde Ventil Unterdruck an den Hohlraum 20 angelegt wird. Die Gleitstücke 18 können auf den Führungsstangen 17 mittels eines Stellhebels 22 verschoben und arretiert werden, so daß die Hilfssaugleiste 19 innerhalb der Ebene des Abstimmtisches 10 und der Grenzen des Kanals 16 frei verschieblich ist. Parallel to the guide 11 of the measuring head are distributed over the width of the table several Bogenanschlãge 12 vorgeseben, to the one placed on the voting table 10 Arch is applied. A main suction list also runs parallel to guide 11 13, which, what Fig2 shows, designed as a square profile and with its cavity 14 can be connected to negative pressure via a valve. In their height Numerous bores 15 are located on the upper side of the plane of the absinthe table 111 attached through which an overlying arch can be sucked. Next to the main suction bar 13 in the direction of the surface of the tuning table 10 is a channel 16, the is spanned by guide rods 17 in the region of its ends. On these guide bars 17 Festigkelmmbare slide pieces 18 are guided, between which, in the channel 16 lying, an auxiliary suction strip 19 extends, the cavity 20 (see FIG. 2) of which everywhere Another valve is connected to a vacuum source via another valve. The top the auxiliary exit bar 19 is located in the plane of the voting table X and is penetrated by BohrEmgen 21, with the help of which an overlying arch is sucked tight can be if via the valve to be controlled Negative pressure on the Cavity 20 is created. The sliding pieces 18 can be placed on the guide rods 17 be moved and locked by means of an adjusting lever 22, so that the auxiliary suction bar 19 within the plane of the voting table 10 and the limits of the channel 16 free is movable.
Die Bogenanschläge 12 sind schwenkbar auf Wellen 23 befestigt, so daß sie über einen Seilzug, eine Zahnleiste od. dgl. unter das Niveau der Tischebene geschwenkt werden kennen. The sheet stops 12 are pivotally mounted on shafts 23, see above that they od via a cable, a toothed bar. Like. Below the level of the table level know to be panned.
Da der Abstand zwischen der Führung 11 für den Meßkopf und seiner Meßblende, mit der die Farbfelder der Farbkontrolleiste abgetastet werden, genau festliegt, ist es erforderlich, daß die Farbkontrolleiste exakt zur Führung 11 ausgerichtet ist. Damit dies auch bei Bogen geschehen kann, bei denen aus den obengenannten Gründen die Lage der Farbkontrolleiste zur Bogenkante nicht oder nicht an allen Stellen den gewünschten Abstand hat, sind nunmehr am Abstimmtisch 10 und im vorliegenden Fall auf der Hauptsaugleiste 13 Ausrichtmarken 24 vorgesehen. Am Bogenrand werden Gegenmarken mitgedruckt, die gemeinsam mit der Farbkontrolleiste auf die Druckplatte aufkopiert werden. Since the distance between the guide 11 for the measuring head and his Measuring aperture with which the color fields of the color control bar are scanned, exactly is fixed, it is necessary that the color control bar is precisely aligned with the guide 11 is. So that this can also be done with arches for which the reasons mentioned above the position of the color control bar to the sheet edge not or not in all places has the desired distance, are now on the voting table 10 and in the present Case on the main suction strip 13 alignment marks 24 are provided. Be at the edge of the sheet Counter marks are also printed, which together with the color control bar on the printing plate be copied.
Damit der Bogen auf dem Abstimmtisch 10 so ausgerichtet ist, daß die Farbkontrolleiste in der exakt richtigen Lage zum traversierenden Meßkopf gehalten ist, wird der Bogen bei hochstehenden Bogenanschlägen 12 auf die Tischplatte aufgelegt und gegen die Bogenanschläge 12 angeschoben. Als nächstes wird, beispielsweise mit Hilfe eines Fußschalters, das Ventil geöffnet, über das an den Hohlraum 20 der Hilfssaugleiste 19 Unterdruck angelegt wird, so daß der Bogen durch die Hilfssaugleiste 19 gehalten ist Gleichzeitig werden die Bogenanschläge 12 unter die Tischfläche geschwenkt Mit Hilfe der Handhebel 22 ist es nun ein Leichtes, durch Verschieben der Hilfssaugleiste 19 die Gegenmarken an den Bogenrändern genau auf die Ausrichtmarken 24 auf der Hauptsaugleiste 13 auszurichten, und wenn das geschehen ist, wird in üblicher Weise das das Unterdrucksystem mit dem Innenraum 14 der Hauptsaugleiste 13 verbindende Ventil geöffnet, so daß der Bogen nunmehr für den anschließenden Abtastvorgang durch den Meßkopf auf dem Abstimmtisch 10 festgehalten und exakt ausgerichtet ist. So that the sheet is aligned on the voting table 10 so that the color control bar is kept in exactly the right position in relation to the traversing measuring head is, the bow is placed on the table top with upright bow stops 12 and pushed against the sheet stops 12. Next, for example with With the help of a foot switch, the valve is opened via the cavity 20 of the auxiliary suction bar 19 negative pressure is applied so that the sheet is held by the auxiliary suction bar 19 At the same time, the sheet stops 12 are pivoted under the table surface With the help of the hand lever 22, it is now easy to move the auxiliary suction bar 19 the counter marks on the sheet edges exactly on the alignment marks 24 on the main suction bar 13 to align, and when that is done, this will be the vacuum system in the usual way with the interior 14 of the main suction strip 13 connecting valve opened so that the sheet now for the subsequent scanning process through the measuring head on the Voting table 10 is held and precisely aligned.
Es versteht sich, daß dann, wenn die Bedienungsperson feststellt, daß die Gegenmarken und die Ausrichtmarken 24 bereits beim ersten Anlegen des Bogens aufeinandertreffen, keinerlei Verschiebung der Hilfssaugleiste 19 erforderlich ist, vielmehr gleich die Hauptsaugleiste 13 eingeschaltet werden kann und der Abtastvorgang beginnt - Leerseite- It goes without saying that if the operator determines that that the counter marks and the alignment marks 24 already when the sheet is first created meet, no displacement of the auxiliary suction strip 19 is required, Rather, the main suction bar 13 can be switched on and the scanning process begins - blank page-
