Abstract

The screen printer has a movable printing table and a suction chamber for the printing material which is connected to a vacuum source via elastic hoses. This suction chamber consists of a suction region which is continuous in the region of the edge of the printing table and which is sealed off from the outside and from the printing material. This design reduces the area subjected to the vacuum, and the available suction capacity results in a more rapid and more intensive build-up of a vacuum in this edge region. This is sufficient to ensure that even stiff or highly curved cardboard boxes are retained firmly and securely on the printing table by suction. <IMAGE>

Description

Die Erfindung betrifft eine Siebdruckmaschine mit einem beweglichen Drucktisch, der eine Ansaugkammer für das Druckgut aufweist, die über elastische Schläuche an eine Unterdruckquelle angeschlossen ist.The invention relates to a screen printing machine with a movable printing table, which has a suction chamber for the printed matter, which is connected to a vacuum source via elastic hoses.

Siebdruckmaschinen dieser Art sind bekannt. Der Drucktisch weist dabei einen Hohlraum auf, der nach oben in der Regel durch eine perforierte Platte abgedeckt ist und über elastische Schläuche mit einer Vakuumpumpe in Verbindung steht. Da der Tisch aus der Druckposition unterhalb des Drucksiebes und der Rakel jeweils wieder in die Anlegeposition zurückgefahren werden muß, wo ein neues Blatt Papier o.dgl. aufgelegt wird, können die den Hohlraum des Drucktisches mit der Vakuumpumpe verbindenden Schläuche nur verhältnismäßig kleine Durchmesser aufweisen, damit sie elastisch genug sind, um die dauernde Bewegung mitzumachen. Die aus dem Hohlraum des Dru-cktisches absaugbare Luftmenge ist daher begrenzt.Screen printing machines of this type are known. The printing table has a cavity which is usually covered at the top by a perforated plate and is connected to a vacuum pump via elastic hoses. Since the table from the printing position below the printing screen and the squeegee must be moved back into the feed position, where a new sheet of paper or the like. is placed, the hoses connecting the cavity of the pressure table to the vacuum pump can only have relatively small diameters so that they are elastic enough to take part in the continuous movement. The amount of air that can be extracted from the cavity of the printing table is therefore limited.

Dieser Umstand kann jedoch beim Druck üblicher dünner Bögen aus Papier o.dgl. hingenommen werden, weil dadurch keine Nachteile für das Festhalten des Druckgutes auf dem Dru-cktisch bestehen. Wenn jedoch relativ steife Materialien, die auch noch dazu neigen, sich etwasdurchzuwölben, wie beispielsweise relativ steife Kartone mit einer Wellpappeinlage o.dgl., bedruckt werden sollen, so reicht der am Drucktisch erzeugte Unterdruck in der Regel nicht aus, um einen sicheren Halt solcher Materialien auf dem Drucktisch zu erreichen.However, this fact can or the like when printing conventional thin sheets of paper or the like. be accepted because there are no disadvantages for holding the printed matter on the printing table. However, if relatively stiff materials that also tend to bulge somewhat, such as relatively stiff cartons with a corrugated cardboard insert or the like, are to be printed, the underpressure generated at the printing table is generally not sufficient to hold them securely Reach materials on the print table.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Siebdruckmaschine der eingangs genannten Art den Drucktisch so auszubilden, daß auch solche steifen Materialien bedruckt werden können.The invention is based, to design the printing table in a screen printing machine of the type mentioned in such a way that even such rigid materials can be printed on the task.

Ausgehend von der Überlegung, daß es ausreicht, das Dru-ckgut nur im Bereich seines Umfanges festzuhalten, besteht die Erfindung darin, daß die Ansaug-kammer als ein im Bereich des Randes des Drucktisches umlaufender Ansaugbereich ausgebildet ist, der nach außen und zum Druckgut hin abgedichtet ist. Durch diese Ausgestaltung wird die vom Unterdruck beaufschlagte Fläche kleiner und die zur Verfügung stehende Absaugkapazität führt zu einem schnelleren und intensiveren Aufbau eines Unterdruckes in diesem umlaufenden Randbereich. Es hat sich gezeigt, daß dies ausreicht, um auch steife und im Ausgangszustand stark gewölbte Kartonagen o.dgl. fest und sicher auf dem Drucktisch festzusaugen. Eine Ansaugung in deren Mittelbereich ist nicht notwendig.Based on the consideration that it is sufficient to hold the printed material only in the area of its circumference, the invention consists in the suction chamber being designed as a suction area running around the edge of the printing table, which extends outwards and towards the printed material is sealed. As a result of this configuration, the area acted upon by the negative pressure becomes smaller and the available suction capacity leads to a faster and more intensive build-up of a negative pressure in this peripheral region. It has been shown that this is sufficient to make even stiff and strongly curved cardboard boxes or the like. to be firmly and securely sucked onto the printing table. A suction in the middle area is not necessary.

Vorteilhaft ist es, wenn der Ansaugbereich aus mehreren Reihen von Ansaugbohrungen mit relativ großen Durchmesser besteht und wenn zur Abdichtung eine rundum verlaufende Dichtung vorgesehen ist, die in eine umlaufende Nut'eingelegt ist. Durch diese Ausgestaltung, bei der der Bohrungsdurchmesser größer gewählt wird als bei handelsüblichen Ansaugdrucktischen, wird der erwünschte schnelle Aufbau des Unterdrucks gefördert. Die Dichtung verhindert, daß Luft von außen eingesaugt wird. " iIt is advantageous if the suction area consists of several rows of suction bores with a relatively large diameter and if an all-round seal is provided for sealing, which is inserted into a circumferential groove. This configuration, in which the bore diameter is chosen larger than that of commercially available suction pressure tables, promotes the desired rapid build-up of the vacuum. The seal prevents air from being sucked in from the outside. "i

Zu diesem Zweck ist es besonders vorteilhaft, wenn die Dichtung mit einer elastisch aus der Nut herausragenden Lippe versehen ist, deren freies Ende zum Rand des Drucktisches gerichtet ist. Diese Ausgestaltung nämlich bringt den Vorteil mit sich, daß auch bei gewölbtem Druckgut in dessen Randbereich durch das Anliegen der hochstehenden Lippendichtung ein weitgehend abgeschlossener Hohlraum zwischen Drucktisch und Druckgut erzeugt wird, der das Einziehen von Falschluft verhindert und so in relativ kurzer Zeit ein sattes Anliegen de Druckgutes auf dem Drucktisch bewirkt.For this purpose, it is particularly advantageous if the seal is provided with a lip which protrudes elastically from the groove, the free end of which is directed towards the edge of the printing table. This embodiment namely has the advantage that even with curved printed material in the edge region by the application of the upstanding lip seal a largely closed cavity between the printing table and the printed material is generated, which prevents the drawing in of false air and thus a rich concern de in a relatively short time Print material causes on the printing table.

Eine weitere vorteilhafte Ausgestaltung ergibt sich dadurch, daß der Ansaugbereich und die Nut mit der Dichtung Teile einer gesondert auf den Drucktisch aufzusetzenden und auswechselbaren Zusatzplatte sind. Diese Ausgestaltung bringt den Vorteil mit sich, daß die Zusat platte jeweils an das zu druckende Gut angepaßt werden kann, ohne daß zu diesem Zweck der Drucktisch selbst eine Änderung erfahren muß.A further advantageous embodiment results from the fact that the suction area and the groove with the seal are parts of a replaceable additional plate which is to be placed separately on the printing table. This configuration has the advantage that the additional plate can be adapted to the product to be printed without the printing table itself having to undergo a change for this purpose.

Die Erfindung ist in der Zeichnung anhand eines Ausführungsbeispiels schematisch dargestellt und wird im folgenden erläutert. Es zeigen:The invention is shown schematically in the drawing using an exemplary embodiment and is explained below. Show it:

  • Fig. 1 eine schematische Draufsicht auf einen Drucktisch einer Siebdruck maschine mit einer aufgelegten Zusatzplatte zur Erzeugung von Unterdruck nur im Randbereich undFig. 1 is a schematic plan view of a printing table of a screen printing machine with an additional plate placed to generate negative pressure only in the edge area and
  • Fig. 2 eine vergrößerte Dar-stellung des Teilschnittes gemäß der Linie II-II in Fig. 1.FIG. 2 shows an enlarged representation of the partial section along the line II-II in FIG. 1.

In den Fig. 1 und 2 ist die Abdeckplatte 1 eines Drucktisches für eine nicht dargestellte Siebdruckmaschine gezeigt, die bekannter Bauart ist und deren Drucktisch zwischen einer Druckposition und einer Aufnahmeposition zum Auflegen des Druckgutes hin und her bewegbar ist. Die Deckplatte ist, wie Fig. 2 entnommen werden kann, dicht auf das Untergestell 2 des Drucktisches aufgesetzt, so daß sich jeweils unterhalb der Abdeckplatte 1 Hohlräume 4 bzw. 5 bilden, die in bekannter Weise über elastische Schläuche mit einer Unterdruckquelle in Verbindung gebracht werden können. Die Abdeckplatte 1 weist einen umlaufenden, durch die strichpunktierte Linie 6 nach innen begrenzten Ansaugbereich 7 auf, der beim Ausführungsbeispiel durch drei Reihen 8, 9 und 10 von Bohrungen 11 gebildet wird. Die Reihen 8, 9 und 10 der Bohrungen 11 verlaufen jeweils parallel zueinander. Weitere öffnungen sind in der Abdeckplatte 1 nicht vorgesehen.1 and 2, the cover plate 1 of a printing table for a screen printing machine, not shown, is shown, which is of a known type and whose printing table can be moved back and forth between a printing position and a receiving position for placing the printed matter. The cover plate, as can be seen in FIG. 2, is placed tightly on the base frame 2 of the printing table, so that cavities 4 and 5 form below the cover plate 1, which are connected in a known manner to a vacuum source via elastic hoses can. The cover plate 1 has a circumferential suction region 7 which is delimited inward by the dash-dotted line 6 and which in the exemplary embodiment is formed by three rows 8, 9 and 10 of bores 11. The rows 8, 9 and 10 of the bores 11 each run parallel to one another. No further openings are provided in the cover plate 1.

Die Abdeckplatte 1 weist außerdem eine umlaufende Nut 12 auf, in der eine ebenfalls umlaufende Dichtung 13 mit einer Dichtlippe 13a eingesetzt ist, deren freies Ende aus der Nut 12 heraus nach oben und in Richtung zum Außenrand 1a der Abdeckplatte 1 gerichtet ist.The cover plate 1 also has a circumferential groove 12 in which a likewise circumferential seal 13 with a sealing lip 13a is inserted, the free end of which is directed upwards out of the groove 12 and in the direction of the outer edge 1a of the cover plate 1.

Unterhalb der Lochreihen 8, 9 und 10 verläuft der Hohlraum 4, der nach außen durch die Wand 4a abgegrenzt ist, der nach innen durch die Wand 4b abgegrenzt sein kann, oder zumindestens zur Abstützung der Deckplatte 1. mit entsprechenden unterbrochenen Stegen 4b gegenüber dem Raum 5 abgeteilt ist. Aus Stabilitätsgründen sind außerdem in dem Hohlraum unterhalb der Abdeckplatte 1 kreuzförmig verlaufende Stützstege (Fig. 1) 14 und 15 vorgesehen, die nicht abdichtend sein müssen, aber dies sein können, wenn die Absaugöffnungen für die Luft aus den Hohlräumen 4, 5 entsprechend angeordnet werden. Beim Ausführungsbeispiel, bei dem die Abdeckplatte 1 nur den umlaufenden Ansaugbereich in der Form der Lochreihen 8, 9 und 10 aufweist, ist eine Unterteilung des Hohlraumes unterhalb der Abdeckplatte 1 nicht notwendig.Below the rows of holes 8, 9 and 10 runs the cavity 4, which is delimited on the outside by the wall 4a, which can be delimited on the inside by the wall 4b, or at least to support the cover plate 1 with corresponding interrupted webs 4b with respect to the room 5 is divided. For stability reasons, cross-shaped support webs (Fig. 1) 14 and 15 are also provided in the cavity below the cover plate 1, which do not have to be sealing, but can be if the suction openings for the air from the cavities 4, 5 are arranged accordingly . In the exemplary embodiment in which the cover plate 1 has only the circumferential suction area in the form of the rows of holes 8, 9 and 10, it is not necessary to subdivide the cavity below the cover plate 1.

Wie aus Fig. 2 erkennbar ist, kann die neue Siebdruckmaschine mit dem neuen Drucktisch zum Anlegen und Bedrucken von relativ steifen und sich im Ausgangszustand nach außen wölbenden Material eingesetzt werden. Wegen der nach oben stehenden Lippe 13a der Dichtung 13 gelingt es nämlich verhältnismäßig einfach, das sich nach oben wölbende Druckgut, beim Ausführungsbeispiel ein Blatt 16 steifen Kartons mit einer Wellpappeinlage, so auf dem Drucktisch anzuordnen, daß der freie Spalt 17 nach außen verhältnismäßig klein bleibt; in den meisten Fällen legt sich das Druckgut 16 im Ausgangszustand am Rand bereits auf das freie Ende der Dichtlippe 13a auf. Wird nun Unterdruck angelegt, so entsteht wegen der relativ geringen rahmenförmigen Ansaugfläche 7 sehr schnell ein hoher Unterdruck; durch den Spalt 17 kann nicht genügend Luft von außen nachströmen, so daß das Druckgut 16 sich spätestens dann an die Lippe 13a anlegt und diese Lippe unter der Wirkung des Unterdruckes im Raum 18 zwischen der Oberfläche der Abdeckplatte 1 und dem Druckgut 16 nach unten in die Nut 12 hereindrückt. Das Druckgut 16 selbst kommt auf diese Weise zu einer satten Anlage auf dem Drucktisch und kann dann ohne Schwierigkeiten in die Druckposition gefahren werden. Nach dem Druck wird der Unterdruck im Raum 4 abgeschaltet. Das Dru-ckgut 16 wird in bekannter Weise durch Greifer gehalten und der Drucktisch fährt wieder zur Aufnahme eines neuen Druckgutes in seine Ausgangsposition zurück.As can be seen from FIG. 2, the new screen printing machine with the new printing table can be used for applying and printing relatively stiff material that bulges outward in the initial state. Because of the upstanding lip 13a of the seal 13, it is relatively easy to arrange the bulging printed material, in the exemplary embodiment a sheet of 16 rigid cardboard boxes with a corrugated cardboard insert, on the printing table in such a way that the free gap 17 remains relatively small to the outside ; in most cases, the printed material 16 in the initial state already lies on the edge of the free end of the sealing lip 13a. If negative pressure is now applied, a high negative pressure very quickly arises because of the relatively small frame-shaped suction surface 7; through the gap 17 not enough air can flow in from the outside, so that the printed material 16 then at the latest bears against the lip 13a and this lip under the effect of the negative pressure in the space 18 between the surface of the cover plate 1 and the printed material 16 down into the Push in 12. In this way, the printed material 16 itself comes to a full contact on the printing table and can then be moved into the printing position without difficulty. After the pressure, the negative pressure in room 4 is switched off. The printed material 16 is held in a known manner by grippers and the printing table moves back to its starting position for receiving a new printed material.

Die Abdeckplatte 1 kann so ausgebildet sein, daß sie leicht vom Drucktisch abnehmbar ist. Sie kann dann den jeweiligen Bedürfnissen angepaßt ausgebildet werden, so daß sie für verschiedenes Druckgut ausgewechselt werden kann und jeweils den optimalen Ansaugeffekt bringt.The cover plate 1 can be designed so that it can be easily removed from the printing table. It can then be adapted to the respective needs, so that it can be exchanged for different printed matter and brings the optimum suction effect in each case.
