Description

Die Erfindung betrifft eine Vorrichtung zur Versorgung eines Farbkastens eines einer Druckmaschine zugeordneten Farbwerks gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for supplying an ink fountain of an inking unit assigned to a printing press according to the preamble of claim 1.

Bei den bekannten Anordnungen dieser Art bilden die Absperrorgane und eine jeweils zugeordnete Antriebseinrichtung jeweils eine Baueinheit, die beim Farbwechsel komplett gewechselt wird. Pro Farbkasten und Farbe ist daher eine derartige Baueinheit erforderlich. Dies ergibt einen hohen baulichen Aufwand. Ein weiterer Nachteil ist in dem hohen Gewicht der genannten Baueinheiten zu sehen, was einen erhöhten Arbeitsaufwand beim Farbwechsel verursacht. Die bekannten Anordnungen erweisen sich demnach als nicht wirtschaftlich und bedienungsfreundlich genug.In the known arrangements of this type, the shut-off elements and an associated drive device each form a structural unit which is completely changed when the color is changed. Such an assembly is therefore required for each ink fountain and color. This results in a high structural effort. Another disadvantage is the high weight of the units mentioned, which causes an increased amount of work when changing colors. The known arrangements therefore prove to be not economical and user-friendly enough.

Aus der EP-A2-0359957 ist eine Druckmaschine bekannt, an der ein Kammerrakel und eine Farbzufuhrvorrichtung lösbar festlegbar sind.A printing machine is known from EP-A2-0359957, on which a chamber doctor blade and an ink supply device can be detachably fixed.

Aus der GB-A-2065 559 ist eine Vorrichtung zum Aufbringen einer abgemessenen Menge flüssiger Farbe auf eine Farbprobenkarte für Malfarben, Kosmetika etc. bekannt, bei welcher eine Pumpe einer Farbzuführvorrichtung austauschbar an einem stationären Absperrorgan festlegbar ist.From GB-A-2065 559 a device for applying a measured amount of liquid paint to a color sample card for stains, cosmetics etc. is known, in which a pump of a paint supply device can be fixed interchangeably to a stationary shut-off device.

Aus der DE-A-1805 853 ist eine Vorrichtung zum Mischen von mehreren Farben zu einem vorgebbaren Farbton bekannt, wobei Einzelkomponenten vorgesehen in denen eine Farbkomponente gespeichert und umgewälzt wird, und von denen die Farbkomponenten zum Mischen abgebbar sind. Die Einzelelemente sind dabei zur Wartung und Pflege abmontierbar und austauschbar.From DE-A-1805 853 a device for mixing several colors to a predeterminable color tone is known, individual components being provided in which a color component is stored and circulated, and from which the color components can be dispensed for mixing. The individual elements can be removed and replaced for maintenance and care.

Es ist die Aufgabe der vorliegenden Erfindung, eine Vorrichtung eingangs erwähnter Art mit einfachen und kostengünstigen Mitteln so zu verbessern, daß trotz geringen Bauaufwands eine hohe Bedienungsfreundlichkeit erreicht wird.It is the object of the present invention to improve a device of the type mentioned at the beginning with simple and inexpensive means in such a way that a high level of user-friendliness is achieved despite the low construction costs.

Diese Aufgabe wird erfindungsgemäß durch das Kennzeichen des Anspruchs 1 gelöst.This object is achieved by the characterizing part of claim 1.

Diese Maßnahmen stelllen sicher, daß pro Verbraucher und Farbe nur eine Antriebseinrichtung benötigt wird. Da es sich hierbei um ein vergleichsweise teures Aggregat handelt, wird hierdurch der erforderliche Bauaufwand gegenüber den bekannten Anordnungen stark reduziert. Gewechselt werden nur die Absperrorgane, die vergleichsweise einfach und kostengünstig sind. Zudem ergibt sich ein vergleichsweise geringes Gewicht der Wechselaggregate, was den beim Farbwechsel erforderlichen Arbeitsaufwand gegenüber den bisherigen Anordnungen ebenfalls stark reduziert.These measures ensure that only one drive device is required per consumer and color. Since this is a comparatively expensive unit, the construction effort required is greatly reduced compared to the known arrangements. Only the shut-off devices are replaced, which are comparatively simple and inexpensive. In addition, there is a comparatively low weight of the changing units, which also greatly reduces the amount of work required for changing the color compared to the previous arrangements.

Erfindungsgemäß sind die Absperrorgane jeweils an einen beweglichen Leitungsabschnitt angesetzt, der mittels eines Schnellverschlusses mit der zugeordneten Farbquelle kuppelbar ist, was die Durchführung des Farbwechsels erleichtert. Pro Farbe kann dabei ein mit der zugeordneten Farbe beaufschlagbarer, stationär angeordneter Verteilerkopf vorgesehen sein, der mit mehreren, den zugeordneten Verbrauchern zugeordneten, jeweils eine Farbquelle bildenden Anschlußnippeln versehen ist. Hiermit läßt sich auch dann eine sehr kompakte Anordnung erreichen, wenn mehrere, einander benachbarte Farbverbraucher zu versorgen sind.According to the invention, the shut-off elements are each attached to a movable line section which can be coupled to the assigned color source by means of a quick-release fastener, which makes it easier to carry out the color change. For each color, a stationarily arranged distribution head can be provided, which can be loaded with the assigned color and is provided with a plurality of connection nipples, each of which forms a color source and is assigned to the assigned consumers. This allows a very compact arrangement to be achieved even if several adjacent color consumers are to be supplied.

Dadurch, daß die Antriebseinrichtung nach Art einer Steckkupplung mit den zugeordneten Absperrorganen kuppelbar ist, ist sichergestellt, daß die Absperrorgane beim Ansetzen an die bzw. Abnehmen von der Antriebseinrichtung automatisch in und außer Antriebsverbindung kommen.The fact that the drive device can be coupled to the associated shut-off elements in the manner of a plug-in coupling ensures that the shut-off elements automatically come into and out of the drive connection when they are attached to or removed from the drive device.

Vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den Unteransprüchen angegeben.Advantageous refinements and appropriate further training of the higher-level measures are specified in the subclaims.

Eine vorteilhafte Maßnahme kann darin bestehen, daß die Absperrorgane mittels eines Rastschlosses am Gehäuse der Antriebseinrichtung lösbar festlegbar sind. Die Antriebsorgane könen dementsprechend einfach durch Ein- bzw. Ausrasten an- bzw. abgebaut werden, was den Farbwechsel sehr erleichtert.An advantageous measure can consist in that the shut-off elements can be releasably fixed to the housing of the drive device by means of a latching lock. Accordingly, the drive elements can be easily attached or detached by snapping in and out, which makes the color change very easy.

Zweckmäßig kann das Rastschloss einerseits vorgesehene, mit Rastnocken versehene Blattfedern aufweisen, deren Rastnocken in zugeordnete, andererseits vorgesehene Rastkerben einrastbar sind. Dies ergibt eine besonders einfache und übersichtliche Bauweise verbunden mit einfacher und leichter Handhabung.The latching lock can expediently have, on the one hand, provided leaf springs provided with latching cams, the latching cams of which can be latched into associated latching notches provided on the other. This results in a particularly simple and clear construction combined with simple and easy handling.

Weitere vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen ergeben sich aus den restlichen Unteransprüchen und sind aus der nachstehenden Beispielsbeschreibung entnehmbar.Further advantageous refinements and expedient further training of the superordinate measures result from the remaining subclaims and can be found in the example description below.

Nachstehend wird ein bevorzugtes Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert. Hierbei zeigen:

A preferred exemplary embodiment of the invention is explained in more detail below with reference to the drawing. Here show:
Figure 1
1 shows a schematic view of a printing unit of a multi-color printing machine,
Figure 2
a front view of a drive device and a shut-off device in the disassembled state and

the arrangement of Figure 2 in the assembled state.

Die der Figur 1 zugrundeliegende Druckmaschineneinheit besteht in an sich bekannter Weise aus einem Maschinengestell 1, auf dem das Druckwerk und die diesem zugeordneten Aggregate aufgenommen sind. Im dargestellten Beispiel soll es sich um ein Doppeldruckwerk handeln, von dem lediglich der untere Plattenzylinder 2 mit zugeordnetem Gummizylinder 3 dargestellt sind. Jedem Plattenzylinder 2 ist ein Farbwerk 4 zugeordnet. Dieses enthält unter anderem einen Farbkasten 5, aus dem eine Tauchwalze 6 Farbe entnimmt.The printing machine unit on which FIG. 1 is based consists, in a manner known per se, of a machine frame 1 on which the printing unit and the ones assigned to it Aggregates are included. In the example shown, it is intended to be a double printing unit, of which only the lower plate cylinder 2 with an associated rubber cylinder 3 are shown. An inking unit 4 is assigned to each plate cylinder 2. This contains, among other things, an ink fountain 5 from which an immersion roller takes 6 ink.

Den Farbkästen 5 wird die jeweils zu verarbeitende Farbe aus hier nicht näher dargestellten Großgebinden zugepumpt. Hierzu sind fest installierte, zu den einzelnen Druckmaschineneinheiten führende Farbleitungen 7a, 7b vorgesehen. Für jede Farbe ist eine derartige Farbleitung 7a bzw. 7b vorgesehen. Im dargestellten Beispiel handelt es sich um zwei Farben. Die Farbleitungen 7a, 7b enden jeweils an einem mit mehreren Anschlußnippeln 8a, 8b versehenen Verteilerkopf 9, der am Maschinengestell 1 befestigt sein kann, wie hier durch eine Konsole 10 angedeutet ist. Die den einzelnen Farben zugeordneten Verteilerköpfe 9 besitzen einen Anschlußnippel 8a bzw. 8b für jeden Farbkasten 5 der zugeordneten Maschineneinheit.The color boxes 5 are pumped with the color to be processed in each case from large containers not shown here. For this purpose, permanently installed ink lines 7a, 7b leading to the individual printing press units are provided. Such a color line 7a or 7b is provided for each color. In the example shown, there are two colors. The color lines 7a, 7b each end at a distributor head 9 provided with a plurality of connecting nipples 8a, 8b, which can be fastened to the machine frame 1, as indicated here by a console 10. The distributor heads 9 assigned to the individual colors have a connection nipple 8a or 8b for each ink fountain 5 of the assigned machine unit.

Die jeweils gewünschte Farbe wird am zugeordneten Anschlußnippel 8a bzw. 8b abgenommen und in den Farbkasten 5 geleitet. Hierzu sind den Farbkästen 5 zugeordnete Einfülleinrichtungen vorgesehen, die alternativ zum Einsatz kommen. Pro Farbkasten und Farbe ist jeweils eine derartige Einfülleinrichtung vorgesehen. Diese Einfülleinrichtungen enthalten ein oberhalb des Farbkastens 5 endendes Einfüllrohr 11, das an ein beispielsweise als Kugelhahn ausgebildetes Absperrorgan 12 angesetzt ist, von dem ein beweglicher Schlauchabschnitt 13 abgeht, der mittels eines Schnellverschlusses 14 am gewünschten Anschlußnippel 8a bzw. 8b anschließbar ist. Das Farbniveau im Farbkasten 5 wird gemessen und durch Auf- bzw. Absteuern des Absperrorgans 12 konstant gehalten. Zur Betätigung des Absperrorgans 12 ist eine Antriebseinrichtung 15 vorgesehen, die als sogenannter Drehantrieb ausgebildet sein kann.The desired color is removed from the assigned connection nipple 8a or 8b and passed into the ink fountain 5. For this purpose, filling devices assigned to the ink fountains 5 are provided, which are used alternatively. Such a filling device is provided for each ink fountain and ink. These filling devices contain a filling tube 11 which ends above the ink fountain 5 and is attached to a shut-off element 12, for example a ball valve, one of which Movable hose section 13 comes off, which can be connected by means of a quick-release fastener 14 to the desired connection nipple 8a or 8b. The color level in the ink fountain 5 is measured and kept constant by opening and closing the shut-off element 12. To actuate the shut-off member 12, a drive device 15 is provided, which can be designed as a so-called rotary drive.

Beim Farbwechsel werden das Einfüllrohr 11 samt Absperrorgan 12 und Schlauchabschnitt 13 gewechselt. Die Antriebseinrichtung 15 bleibt in Stellung. Diese ist stationär angeordnet, d.h. dem zugeordneten Verbraucher fest zugeordnet. Im dargestellten Beispiel ist die Antriebseinrichtung 15 an einer Traverse 16 des Maschinengestells 1 befestigt. Es wäre aber auch denkbar, die Antriebseinrichtung 15 zusammen mit den Verteilerköpfen 9 auf ein und derselben Halteeinrichtung aufzunehmen. Pro Verbraucher, also hier pro Farbkasten 5, wird nur eine Antriebseinrichtung 15 benötigt, an die das jeweils zum Einsatz kommende Absperrorgan 12 lösbar ansetzbar und antriebsmäßig ankuppelbar ist. Das zum Einsatz kommende Absperrorgan 12 samt Einfüllrohr 11 und Schlauchabschnitt 13 wird im Einbauzustand von der Maschinen fest angeordneten Antriebseinrichtung 15 getragen, so daß keine zusätzliche maschinenseitige Abstützung erforderlich ist. Zur Verbindung von Antriebseinrichtung 15 und Absperrorgan 12 sind dementsprechend eine geeignete Halteeinrichtung sowie eine Kupplungseinrichtung erforderlich.When changing colors, the filler pipe 11 together with the shut-off device 12 and the hose section 13 are changed. The drive device 15 remains in position. This is arranged in a stationary manner, ie permanently assigned to the assigned consumer. In the example shown, the drive device 15 is fastened to a cross member 16 of the machine frame 1. However, it would also be conceivable to accommodate the drive device 15 together with the distributor heads 9 on one and the same holding device. Only one drive device 15 is required per consumer, that is to say here per ink fountain 5, to which the shut-off element 12 used in each case can be detachably attached and can be coupled in terms of drive. The shut-off device 12 used, together with the filler pipe 11 and hose section 13, is carried in the installed state by the drive device 15 which is fixedly arranged in the machine, so that no additional machine-side support is required. A suitable holding device and a coupling device are accordingly required for connecting the drive device 15 and the shut-off device 12.

Die Absperrorgane 12 sind, wie am besten aus Figuren 2 und 3 erkennbar ist, an einem hier durch einen Rechteckrohrabschnitt gebildeten Trägerprofil 17 befestigt, das einander gegenüberliegende Blattfedern 18 trägt, deren das Trägerprofil 17 überragende Enden mit durch nach innen gebogene Abwinklungen gebildeten Rastnocken 19 versehen sind. Das Gehäuse der Antriebseinrichtung 15 ist an der ihrem Abtrieb 20 zugeordneten Seite mit einem beispielsweise durch den Abtrieb 20 flankierende Leisten gebildeten Anbaufuß 21 versehen, an den das Trägerprofil 17 ansetzbar ist. Der Anbaufuß 21 ist an den den Blattfedern 18 zugeordneten Seiten mit dachförmig gegeneinander geneigten Flanken versehen, so daß sich den Rastnocken 19 zugeordnete Rastkerben 22 ergeben. Zum Anbauen des Absperrorgans 12 wird dieses an die Antriebseinrichtung 15 so angesteckt, daß die Rastnocken 19 zum Eingriff mit den Rastkerben 22 kommen.The shut-off devices 12, as can best be seen from FIGS. 2 and 3, are fastened to a support profile 17 formed here by a rectangular tube section, which supports opposite leaf springs 18, the ends of which project beyond the support profile 17 and are provided with locking cams 19 formed by inwardly bent bends are. The housing of the drive device 15 is provided on the side assigned to its output 20 with a mounting foot 21, for example formed by strips flanking the output 20, to which the carrier profile 17 can be attached. The mounting foot 21 is provided on the sides associated with the leaf springs 18 with roof-shaped inclined flanks, so that the locking cams 19 associated locking notches 22 result. To attach the shut-off element 12, it is attached to the drive device 15 such that the locking cams 19 come into engagement with the locking notches 22.

Anstelle einer als Rastschloss ausgebildeten Halteeinrichtung könnte selbstverständlich auch eine Magnetverbindung oder ein Bajonettverschluß oder dergleichen vorgesehen sein. Zur Sicherung der Position und zur Bewerkstelligung einer Verdrehsicherung können die Stoßfuge zwischen Anbaufuß 21 und Trägerprofil 17 durchgreifende Stifte 23 vorgesehen sein, die hier am Anbaufuß 21 befestigt und in zugeordnete Bohrungen 24 des oberen Stegs des Trägerprofils 17 zum Eingriff bringbar sind.Instead of a holding device designed as a latching lock, a magnetic connection or a bayonet lock or the like could of course also be provided. To secure the position and to achieve an anti-rotation device, the butt joint between mounting foot 21 and support profile 17 can be provided through pins 23 which are fastened here to the mounting foot 21 and can be brought into engagement in associated bores 24 of the upper web of the support profile 17.

Das hier durch Rastverschluß an der Antriebseinrichtung festlegbare Absperrorgan 12 wird mit dem Abtrieb 20 des Antriebsorgans 15 antriebsmäßig nach Art einer Steckkupplung gekuppelt, die gleichgerichtet wie die im dargestellten Beispiel als Rastschloss ausgebildete Halteeinrichtung in- und außer Eingriff bringbar ist, so daß sowohl die Halteeinrichtung als auch die Kupplungseinrichtung praktisch mit demselben Handgriff in- und außer Eingriff bringbar sind. Hierzu sind die Absperrorgane 12 jeweils mit einem Antriebsstummel 25 versehen, der das zugeordnete Trägerprofil 17 durchgreift und an seinem darüber vorstehenden Ende ein Steckkupplungselement, hier in Form eines Vierkants 26, aufweist. Der Abtrieb 20 der Antriebseinrichtung 15 besitzt eine das zugeordnete Steckkupplungselement bildende Vierkantausnehmung 27, in die der Vierkant 26 beim Ansetzen des Absperrorgans 12 an die Antriebseinrichtung 15 einschiebbar ist, wie in Figur 2 durch einen Pfeil angedeutet ist.The shut-off device 12 which can be fixed here by a snap lock on the drive device is driven with the output 20 of the drive member 15 in the manner of a plug-in coupling coupled, which can be brought in and out of engagement in the same direction as the holding device designed as a latching lock in the example shown, so that both the holding device and the coupling device can be brought in and out of engagement practically with the same handle. For this purpose, the shut-off elements 12 are each provided with a drive stub 25 which passes through the associated support profile 17 and has a plug-in coupling element, here in the form of a square 26, at its end projecting above it. The output 20 of the drive device 15 has a square recess 27 forming the associated plug-in coupling element, into which the square 26 can be inserted when the shut-off element 12 is attached to the drive device 15, as indicated in FIG. 2 by an arrow.

Zur Durchführung eines Farbwechsels werden das der bisherigen Farbe zugeordnete Absperrorgan 12 samt Einfüllrohr 11 und Schlauchabschnitt 13 hier einfach durch Abziehen von der Antriebseinrichtung 15 abgenommen und der Schnellverschluß 14 gelöst. Anschließend wird das der neuen Farbe zugeordnete Absperrorgan samt hieran aufgenommenem Einfüllrohr und Schlauchabschnitt durch Aufschieben an der Antriebseinrichtung 15 gehaltert und hiermit in Antriebsverbindung gebracht sowie die Schnellkupplung 14 an den zugeordneten Anschlußnippel 8a bzw. 8b angeschlossen. Da die Antriebseinrichtung 15 in Stellung bleibt, ergeben sich gewichtsmäßig vergleichsweise leichte Wechseleinheiten, die einfach gehandhabt werden können. Da die Antriebseinrichtung 15 pro Farbkasten nur einmal benötigt wird, ergibt sich auch ein vergleichsweise geringer Aufwand.To carry out a color change, the shut-off device 12 associated with the previous color, including filler pipe 11 and hose section 13, are simply removed from the drive device 15 by pulling them off and the quick-release fastener 14 is released. Then the shut-off device assigned to the new color, together with the filler pipe and hose section accommodated thereon, is held on the drive device 15 by sliding it on and brought into drive connection, and the quick coupling 14 is connected to the assigned connection nipple 8a or 8b. Since the drive device 15 remains in position, there are comparatively light exchange units in terms of weight, which can be easily handled. Since the drive device 15 per ink fountain only once required, there is also comparatively little effort.
