Abstract

The invention relates to a drive device for driving pump units, which are used for paint-spraying. The drive device comprises a pneumatic drive motor 1 having a piston 2 which can move reciprocatingly in a cylinder 3. Fastened to the piston 2 are pump tappets 4 to 6, which in their turn are coupled with the pump units. To minimise overall length and to prevent jamming of the pump tappets, the invention provides for the pump tappets 4 to 6 each to be directly fastened to the piston 2 and to be guided on a first 7 and/or a second 8 casing plate of the cylinder 3. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Antriebsvorrichtung zum Antrieb mindestens zweier Pumpenaggregate, mit einem pneumatischen Antriebsmotor, welcher einen in einem Zylinder reziprok verschiebbaren Kolben umfaßt, welcher mit zumindest zwei mit dem Kolben bewegbaren Pumpenstößeln gekoppelt ist.The invention relates to a drive device for driving at least two pump units, with a pneumatic drive motor, which comprises a piston reciprocally displaceable in a cylinder, which is coupled to at least two pump tappets movable with the piston.

Antriebsvorrichtungen der oben beschriebenen Art werden insbesondere zum Antrieb von Farbspritzen verwendet. Der beschriebene Luftmotor ist in seinem Aufbau besonders einfach und wartungsfreundlich, so daß seine Verwendung zum Antrieb eines Pumpenaggregates vielfältige Vorteile bringt. Der Nachteil eines derartigen Luftmotors liegt darin, daß die an dem Kolben befestigte Kolbenstange mit einer Einrichtung verbunden werden muß, welche es gestattet, mehrere Farbspritzpumpenaggregate gleichzeitig und synchron zu betätigen. Es wurde deshalb bisher an die Kolbenstange ein Joch angekoppelt, welches mit einzelnen Pumpenstößeln verbunden war, welche wiederum den jeweiligen Pumpenaggregaten zugeordnet waren. Dieser relativ komplizierte mechanische Aufbau führt zu dem Nachteil, daß die einzelnen Pumpenstößel ebenso wie die Kolbenstange außerhalb des Luftmotors geführt werden müssen. Hieraus ergibt sich eine relativ große Baulänge, weiterhin erfordert diese Ausgestaltung einen erheblichen konstruktiven Aufwand. Die vergrößerte Baulänge der gesamten Antriebsvorrichtung führt weiterhin zu dem Nachteil, daß sowohl die Kolbenstange als auch die einzelnen Pumpenstößel sehr stark auf Kippen beansprucht sind. Diese Beanspruchung tritt insbesondere dann auf, wenn eine der mehreren Pumpenaggregate ausfällt, da die unterschiedliche Druckbelastung zu einer unterschiedlichen Krafteinleitung auf das Joch führt. Die Kippbeanspruchung führt wiederum zu einer verstärkten Belastung der Lagerteile, Dichtungen, und ähnlichem, wodurch der Verschleiß erheblich verstärkt wird.Drive devices of the type described above are used in particular for driving paint sprayers. The construction of the air motor described is particularly simple and easy to maintain, so that its use for driving a pump unit brings a variety of advantages. The disadvantage of such an air motor is that the piston rod attached to the piston must be connected to a device which allows several paint spray pump units to be operated simultaneously and synchronously. For this reason, a yoke was previously coupled to the piston rod, which was connected to individual pump tappets, which in turn connected the respective pump units were assigned. This relatively complicated mechanical structure leads to the disadvantage that the individual pump tappets and the piston rod must be guided outside the air motor. This results in a relatively large overall length, and this configuration also requires considerable construction effort. The increased overall length of the entire drive device also leads to the disadvantage that both the piston rod and the individual pump tappets are very heavily used on tilting. This stress occurs in particular when one of the several pump units fails, since the different pressure loads lead to a different application of force to the yoke. The tipping stress in turn leads to an increased load on the bearing parts, seals, and the like, which significantly increases wear.

Der Erfindung liegt die Aufgabe zugrunde, eine Antriebsvorrichtung der eingangs genannten Art zu schaffen, welche bei einfachem Aufbau und einfacher, kostengünstiger Herstellbarkeit die Nachteile des Standes der Technik vermeidet, eine kompakte Baugröße aufweist und ein hohes Maß an Störungssicherheit beinhaltet.The invention has for its object to provide a drive device of the type mentioned, which avoids the disadvantages of the prior art with a simple structure and simple, inexpensive to manufacture, has a compact size and includes a high degree of reliability.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die Pumpenstößel jeweils an dem Kolben befestigt sind und an einer ersten und/oder einer zweiten Gehäuseplatte des Zylinders geführt sind.According to the invention the object is achieved in that the pump tappets are each attached to the piston and are guided on a first and / or a second housing plate of the cylinder.

Die erfindungsgemäße Antriebsvorrichtung zeichnet sich durch eine Reihe erheblicher Vorteile aus. Da erfindungsgemäß die einzelnen Pumpenstößel direkt an dem pneumatischen Antriebsmotor gelagert sind, kann auf das aus dem Stand der Technik bekannte Joch vollständig verzichtet werden. Es ergibt sich somit eine erhebliche Verkürzung der Baulänge.The drive device according to the invention is characterized by a number of considerable advantages. Since, according to the invention, the individual pump tappets are mounted directly on the pneumatic drive motor, the yoke known from the prior art can be completely dispensed with. This results in a considerable reduction in the overall length.

Weiterhin ist die Kippgefahr im wesentlichen beseitigt, da jeder Pumpenstößel für sich an dem Antriebsmotor gelagert ist, so daß eine ungleichmäßige Belastung der einzelnen Pumpenstößel durch unterschiedliche Pumpkräfte die gesamte Baueinheit nicht beeinträchtigt, sondern lediglich zu einer unterschiedlichen Belastung des Pumpenstößels selbst führt. All dies führt zu einer erheblichen Verminderung des Verschleisses, so daß die Lebensdauer der Antriebsvorrichtung, verglichen mit der aus dem Stand der Technik bekannten Ausgestaltungsform wesentlich erhöht ist.Furthermore, the risk of tipping is substantially eliminated, since each pump tappet is mounted on the drive motor, so that an uneven loading of the individual pump tappets by different pumping forces does not affect the entire assembly, but only leads to a different loading of the pump tappet itself. All this leads to a considerable reduction in wear, so that the service life of the drive device is significantly increased compared to the embodiment known from the prior art.

In einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, daß der Pumpenstößel einstückig mit einem an einer der Gehäuseplatten geführten Lagerstößel ausgebildet ist. Diese Ausgestaltungsform bringt den Vorteil mit sich, daß der Durchmesser des Lagerstößels geringer gewählt werden kann, als der Durchmesser des Pumpenstößels, so daß sich geringere Abmessungen der Dichtungen erzielen lassen.In a preferred development of the invention it is provided that the pump tappet is formed in one piece with a bearing tappet guided on one of the housing plates. This embodiment has the advantage that the diameter of the bearing tappet can be chosen smaller than the diameter of the pump tappet, so that smaller dimensions of the seals can be achieved.

Der Pumpenstößel ist bevorzugter Weise an seinem freien Ende mit einem Anschlußelement versehen, um das nachfolgende Pumpenaggregat ankoppeln zu können. Dabei ist es besonders günstig, wenn eine Kippmöglichkeit im Übergangsbereich zwischen dem Pumpenstößel und dem Pumpenaggregat vorgesehen ist, um die Einleitung von Kippkräften auf den Pumpenstößel zu minimieren. Weiterhin kann das Anschlußelement mit einer Verdrehsicherung verbunden sein, welche beispielsweise einen parallel zu dem Pumpenstößel angeordneten Bolzen umfaßt, so daß bei der reziproken Bewegung des Pumpenstößels Drehungen desselben vermieden werden.The pump tappet is preferably provided with a connecting element at its free end in order to be able to couple the subsequent pump unit. It is particularly advantageous if a tilting possibility is provided in the transition area between the pump tappet and the pump assembly in order to minimize the introduction of tipping forces on the pump tappet. Furthermore, the connection element can be connected to an anti-rotation device which, for example, comprises a bolt arranged parallel to the pump tappet, so that rotations thereof are avoided during the reciprocal movement of the pump tappet.

Zur Betätigung des Antriebsmotors kann einer der Pumpenstößel mit einer Steuerstange zur Steuerung der Luftzufuhr zu dem Antriebsmotor versehen sein. Die Steuerstange kann beispielsweise längenverschiebbar an dem Pumpenstößel bzw. in demselben geführt sein, wobei das dem Pumpenstößel abgewandte Ende der Steuerstange mit einem Umschalter verbunden sein kann, um die Luftzufuhr zu dem pneumatischen Antriebsmotor zu steuern.To actuate the drive motor, one of the pump tappets can be provided with a control rod for controlling the air supply to the drive motor. The control rod can be displaceable in length on the pump tappet, for example or be guided in the same, wherein the end of the control rod facing away from the pump tappet can be connected to a changeover switch in order to control the air supply to the pneumatic drive motor.

In einer besonders günstigen Ausgestaltungsform der Erfindung ist der Pumpenstößel so dimensioniert, daß er eine Baulänge aufweist, welche im wesentlichen gleich zu der doppelten Hublänge des Kolbens ist. Hierdurch ergibt sich eine besonders kompakte Ausgestaltung der Antriebsvorrichtung.In a particularly favorable embodiment of the invention, the pump tappet is dimensioned such that it has an overall length which is essentially equal to twice the stroke length of the piston. This results in a particularly compact design of the drive device.

Im folgenden wird die Erfindung anhand eines Ausführungsbeispieles in Verbindung mit der Zeichnung beschrieben. Dabei zeigt:

  • Fig. 1 eine vereinfachte Seitenansicht, teils im Schnitt, eines Ausführungsbeispieles der erfindungsgemäßen Antriebsvorrichtung.
The invention is described below using an exemplary embodiment in conjunction with the drawing. It shows:
  • Fig. 1 is a simplified side view, partly in section, of an embodiment of the drive device according to the invention.

Die in Fig. 1 gezeigt Antriebsvorrichtung umfaßt einen pneumatischen Antriebsmotor 1, welcher einen Kolben 2 aufweist, welcher wiederum reziprok in einem Zylinder 3 hin und her bewegbar ist. Der Kolben 2 ist in üblicher Weise mittels einer Kolbendichtung 12 gegen den Zylinder 3 abgedichtet. In Fig. 1 ist auf die Darstellung der Luftzufuhr bzw. Luftabfuhr verzichtet worden, da diese zum Stand der Technik gehört. Die beiden Arbeitsräume des pneumatischen Antriebsmotors 1 werden durch eine erste Gehäuseplatte 7 und eine zweite Gehäuseplatte 8 begrenzt, diese sind über Stehbolzen 13 miteinander verbunden.The drive device shown in FIG. 1 comprises a pneumatic drive motor 1 which has a piston 2, which in turn is reciprocally movable in a cylinder 3. The piston 2 is sealed against the cylinder 3 in the usual way by means of a piston seal 12. In Fig. 1, the representation of the air supply or air discharge has been omitted, since this is part of the prior art. The two working spaces of the pneumatic drive motor 1 are delimited by a first housing plate 7 and a second housing plate 8, these are connected to one another via stud bolts 13.

Die Fig. 1 in schematischer Weise weiterhin einen Schalldämpfer 14 und eine Steuergehäuse 15. Diese entsprechen ebenfalls dem Stand der Technik, so daß auf eine dezidierte Beschreibung ebenfalls verzichtet werden kann. In Fig. 1 ist weiterhin zur übersichtlicheren Darstellung der Erfindung die Steuerstange weggelassen worden, mit Hilfe derer der Antriebsmotor gesteuert wird und die üblicher Weise mit dem Kolben 2 betriebsverbunden ist.1 further schematically shows a muffler 14 and a control housing 15. These also correspond to the prior art, so that a dedicated description can also be dispensed with. In Fig. 1 the control rod, by means of which the drive motor is controlled and which is normally operationally connected to the piston 2, has been omitted for a clearer illustration of the invention.

Erfindungsgemäß sind drei Pumpenstößel 4, 5 und 6 vorgesehen, welche jeweils über eine Dichtung 16 an der zweiten Gehäuseplatte 8 verschiebbar gelagert sind. Die Pumpenstößel 4 bis 6 sind fest mit dem Kolben 2 verbunden, wobei die Ankoppelung über eine Buchse 17 erfolgt. Die beiden äußeren Pumpenstößel 4 und 6 sind jeweils einstückig mit einem Lagerstößel 9 ausgebildet, welcher über eine Dichtung 18 an der ersten, oberen Gehäuseplatte 7 geführt ist. Die Pumpenstößel 4 und 6 sind somit verkippsicher direkt an dem pneumatischen Antriebsmotor 1 gelagert.According to the invention, three pump tappets 4, 5 and 6 are provided, which are each slidably mounted on the second housing plate 8 via a seal 16. The pump tappets 4 to 6 are firmly connected to the piston 2, the coupling being carried out via a bushing 17. The two outer pump tappets 4 and 6 are each formed in one piece with a bearing tappet 9, which is guided on the first, upper housing plate 7 via a seal 18. The pump tappets 4 and 6 are thus mounted directly on the pneumatic drive motor 1 so that they cannot tip over.

An den freien Enden der Pumpenstößel 4 bis 6 ist jeweils ein Anschlußelement 10 befestigt, welches im wesentlichen plattenförmig ausgebildet ist und sich in Eingriff mit jeweils einem Bolzen 11 befindet, der als Verdrehsicherung wirkt, um eine Drehung der Pumpenstößel 4 bis 6 während des reziproken Bewegungsvorganges zu vermeiden. Die Anschlußelemente 10 sind jeweils mit einem nur schematisch dargestellten Pumpenaggregat 19 verbunden, welches zum Antrieb von Farbspritzgeräten dient.At the free ends of the pump tappets 4 to 6, a connection element 10 is fastened, which is essentially plate-shaped and is in engagement with a bolt 11, which acts as an anti-rotation device, to rotate the pump tappets 4 to 6 during the reciprocal movement process to avoid. The connection elements 10 are each connected to a pump unit 19, only shown schematically, which is used to drive paint spraying devices.

Die Erfindung ist nicht auf das gezeigte Ausführungsbeispiel beschränkt, vielmehr ergeben sich für den Fachmann im Rahmen der Erfindung vielfältige Abwandlungs- und Modifikationsmöglichkeiten.The invention is not limited to the exemplary embodiment shown, but there are various modification and modification possibilities for the person skilled in the art within the scope of the invention.
