Description
Die Erfindung betrifft eine Klebstoffauftragsvorrichtung mit einer Klebstoff aufnehmenden Klebstoffkammer, deren vordere Seite durch eine Klebstoffwalze mit vertikaler Drehachse, die mit einer vertikalen Seitenwand der Kammer einen Rückförderspalt für nicht abgenommene Klebstoffaufträge begrenzt, und durch eine zu dieser parallele Dichtwalze geschlossen ist, die mit der Klebstoffwalze einen Klebstoffdurchtrittsspalt bildet und durch Abdichtmittel gegenüber der anderen vertikalen Seitenwand der Kammer abgedichtet ist, mit einer an die Klebstoffwalze anstellbaren Klebstoffauftrags- oder Klischeewalze, die vorzugsweise formatmäßig Leimaufträge von dieser übernimmt und auf mit einem Klebstoffauftrag zu versehende Werkstücke überträgt, und mit einem schwenkbar gelagerten und mit einem Antrieb versehenen Stellhebel, in dem exzentrisch zu dessen Schwenkachse mit einer Exzentrizität, die kleiner ist als der Radius der Klischeewalze, die Klischeewalze gelagert ist und der die Klischeewalze von dem Werkstückträger abrückt, wenn mit einem Klebstoffauftrag zu versehende Werkstücke ausbleiben.The invention relates to an adhesive application device with an adhesive receiving Adhesive chamber, the front side of which is held by an adhesive roller with vertical Axis of rotation with a vertical side wall of the chamber a return gap limited for adhesive orders not accepted, and by one to this parallel sealing roller is closed, with the adhesive roller an adhesive passage gap forms and by sealing means against the other vertical side wall the chamber is sealed, with an adhesive application device that can be positioned on the adhesive roller or cliché roller, which is preferably in the format of glue this takes over and on workpieces to be applied with an adhesive transmits, and with a pivoted and provided with a drive Control lever in which eccentric to its pivot axis with an eccentricity that is smaller than the radius of the plate roller, the plate roller is mounted and the the plate roller moves away from the workpiece carrier when applying an adhesive No workpieces to be provided.
Eine Klebstoffauftragsvorrichtung der eingangs angegebenen Art ist beispielsweise aus DE-C-19532582 bekannt. Bei derartigen Vorrichtungen muß die Klischeewalze von dem beispielsweise aus einem Greiferzylinder bestehenden Werkstoffträger abgerückt werden, wenn dieser keine mit einem Klebstoffauftrag zu versehende Werkstücke transportiert, damit der Werkstückträger bzw. der Greiferzylinder nicht durch Leimaufträge verschmiert werden. An adhesive application device of the type specified at the outset is, for example known from DE-C-19532582. In such devices, the cliché roller moved away from the material carrier consisting, for example, of a gripper cylinder if this is not an adhesive application Workpieces transported so that the workpiece carrier or the gripper cylinder does not be smeared with glue.
Bei dem Abrücken der Klischeewalze vom Werkstückträger ergibt sich das Problem, daß möglichst der Abstand der Klischees zu der Klebstoffwalze nicht verändert werden soll, damit die Gleichmäßigkeit des Klebstoffauftrags auf die Klischees nicht beeinträchtigt wird und die Klischees auch nicht gequetscht werden.When the cliché roller moves away from the workpiece carrier, the problem arises that as far as possible the distance between the clichés and the adhesive roller is not changed So that the uniformity of the adhesive application on the clichés is not is impaired and the clichés are not squashed.
Anhand der Fig. 3 bis 5 der Zeichnung wird eine schwenkbare Lagerung der Klischeewalze
beschrieben, bei der bei einem Abrücken von dem Werkstückträger der
Abstand der Drehachse der Klischeewalze zu der Drehachse der Klebstoffwalze
konstant bleibt. Die mit dem Klischee 3 versehene Klischeewalze 2 ist in der Lagerung
6 in einem Hebel 4 drehbar gelagert, der seinerseits um die Drehachse 5 der
Klebstoffwalze 1 schwenkbar gelagert ist. Die Bahn der kontinuierlich geöfrderten
und mit einem Klebstoffauftrag zu versehenden Werkstücke ist durch den Pfeil A
angedeutet. Soll die Klischeewalze 2, 3 von dem Werkstückträger abgerückt werden,
wird ein Antrieb, beispielsweise ein Pneumatikzylinder 7, betätigt, der den Hebel
4 zwischen den gestellfesten Anschlägen 8, 9 verschwenkt. Da während dieses
Verschwenkens die Drehachse des Klischeezylinders 2 auf einem zu der Drehachse
5 der Klebstoffwalze 1 konzentrischen Hüllzylinder, der durch den Pfeil B angedeutet
ist, verschwenkt wird, ändert sich der Abstand der Drehachse
des Klischeezylinders zu der Drehachse der Klebstoffwalze
1 nicht. Aus Fig. 4 ist ersichtlich, daß das Klischee 3 des Klischeezylinders
2 in jeder Schwenklage des Stellhebels 4 Klebstoffaufträge
gleicher Dicke von der Klebstoffwalze 1 abnimmt.
Aus Fig. 5 ist ersichtlich, daß bei einem Verschwenken des Stellhebels
4 das Klischee 3 keiner Abstandsänderung zu dem Mantel
der Klebstoffwalze 1 unterliegt.3 to 5 of the drawing is a pivotable mounting of the plate roller
described in which when moving away from the workpiece carrier
Distance of the axis of rotation of the plate roller to the axis of rotation of the adhesive roller
remains constant. The
Die aus den Fig. 3 bis 5 ersichtliche Anordnung hat jedoch den
Nachteil, daß die Klischeewalze 2 an einem relativ langen Hebel
mit verhältnismäßig großem Abstand von dessen Schwenkachse gelagert
ist, der zum Abrücken und Anstellen der Klischeewalze mit
einem kleineren Schwenkwinkel verschwenkt werden muß, so daß bei
einem Verschwenken erhebliche Massen stark beschleunigt und abgebremst
werden müssen, was bei der hohen Geschwindigkeit, mit der
das An- und Abstellen erfolgt, wegen der sich aus den großen Beschleunigungen
ergebenden großen Massenkräften problematisch
ist.The arrangement shown in FIGS. 3 to 5 has the
Disadvantage that the
Um die bei einem Ab- und Anstellen der Klischeewalze zu beschleunigenden
und abzubremsenden Massen beherrschbarer zu machen, ist
es, wie anhand der Fig. 6 bis 8 erläutert wird, aus einer Vorrichtung
der eingangs angegebenen Art bekannt, die Klischeewalze
2 in einem kürzeren Hebel 10 zu lagern, dessen Schwenkachse 11
von der Drehachse 12 des Klischeezylinders 2 einen Abstand aufweist,
der kleiner ist als der Radius der Klischeewalze. Diese
Anordnung hat jedoch, wie aus Fig. 7 ersichtlich ist, den Nachteil,
daß bei einem Abschwenken der Klischeewalze 2 von dem Werkstückträger
die Drehachse 12 des Klischeezylinders in die Stellung
12' verschwenkt wird, in der sie von dem zu der Drehachse 5
der Klebstoffwalze 1 konzentrischen Hüllzylinder B mit dem Radius
R nach innen hin abweicht, so daß sich die Drehachsen 12, 5
der Klischeewalze und der Klebstoffwalze einander annähern und
das Klischee in der aus den Fig. 7 und 8 ersichtlichen Weise gequetscht
wird. Diese Quetschung, die eine gleichmäßige Klebstoffaufnahme
während des Abstellens verhindert, ist nachteilig, wurde
jedoch in Kauf genommen.To accelerate those when the cliché roller is switched off and on
and to make the braked masses more manageable
it, as will be explained with reference to FIGS. 6 to 8, from a device
the cliché roller known at the
Aufgabe der Erfindung ist es, eine Klebstoffauftragsvorrichtung der eingangs angegebenen Art zu schaffen, bei der sich bei Verringerung der sich aus den Beschleunigungen ergebenden Massenkräfte bei einem Ab- und Anstellen der Klischeewalze an den Werkstückträger der Abstand der Drehachse der Klischeewalze zu der Drehachse der Klebstoffwalze nicht ändert.The object of the invention is an adhesive application device to create the type specified at the beginning, when reducing the mass forces resulting from the accelerations when the cliché roller is put on and off on the workpiece carrier the distance of the axis of rotation of the plate roller to that The axis of rotation of the adhesive roller does not change.
Erfindungsgemäß wird diese Aufgabe bei einer Klebstoffauftragsvorrichtung der eingangs angegebenen Art dadurch gelöst, daß die Drehachse des Klischeezylinders oder die Drehachse der Klebstoffwalze derart beweglich geführt sind, daß der Abstand der Klischeewalze zur Klebstoffwalze gleichbleibt.According to the invention, this object is achieved with an adhesive application device of the type specified in that the Axis of rotation of the plate cylinder or the axis of rotation of the adhesive roller are guided so that the distance between the plate roller to the adhesive roller remains the same.
Bei der spezielleren, beispielsweise aus der DE-195 32 582.6 bekannten Klebstoffauftragsvorrichtung, die oben im zweiten Absatz näher beschrieben ist, wird die Aufgabe dadurch gelöst, daß die aus Klebstoffkammer mit Klebstoff- und Dichtwalze bestehende Einheit um eine seitliche, zu der Achse der Klischeewalze parallele Achse schwenkbar gelagert und zwischen einem zu der Achse der Klebstoffwalze konzentrischen Zapfen oder Sektor und einer mit dem Stellhebel verdrehbaren Steuerkurve ein beweglich gelagertes Abstandselement angeordnet ist, daß eine die Einheit beaufschlagende federnde Einrichtung den Zapfen der Klebstoffwalze an das Abstandselement andrückt und daß die Charakteristik der Steuerkurve so gewählt ist, daß bei einem Verschwenken des Stellhebels der Abstand der Achsen der Klebstoffwalze und der Klischeewalze konstant bleibt. In the more specific, for example from DE-195 32 582.6 known adhesive application device, the above in the second Paragraph is described in more detail, the task is solved by that the existing from the adhesive chamber with adhesive and sealing roller Unit around a side, to the axis of the plate roller parallel axis pivoted and between one to the Axis of the adhesive roller concentric pin or sector and a control cam rotatable with the control lever a movable stored spacer is arranged that the unit resilient device acting on the pin of the adhesive roller presses against the spacer element and that the characteristic the control curve is selected so that when the Lever the distance between the axes of the adhesive roller and the Cliché roller remains constant.

Zweckmäßigerweise besteht das Abstandselement aus einem im Maschinengestell schwenkbar gelagerten Hebel mit zu der Klischeewalzenachse paralleler Schwenkachse.The spacer element expediently consists of a in the machine frame pivoted lever with to the cliché roller axis parallel pivot axis.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß sich das Abstandselement über einen einstellbaren Exzenter auf dem Zapfen der Klebstoffwalze abstützt, so daß sich die Dicke des von dem Klischee von der Klebstoffwalze abgenommenen Klebstoffauftrags einstellen läßt.In a further embodiment of the invention it is provided that the spacer via an adjustable eccentric on the Supports the adhesive roller so that the thickness of the adhesive application removed from the cliché by the adhesive roller can be adjusted.
