Feeding and braking mechanism, in a labelling machine, for a roll of labels (8', 8") which can be drawn over a dispensing edge and carries self-adhesive labels spaced apart from one another, having a drive roller (1) fixedly mounted behind the dispensing edge (24) in the feed direction and a counter-pressure roller (11) which can be pressed against the drive roller (1), thereby trapping the reversing portion (8") of the label roll, and having a roll brake comprising a fixedly mounted stopper (2) and a counter-pressure stopper (3) which can be pressed against the former stopper (2) so as to trap the label roll (8', 8") between them, and having a lever (6) swivel-mounted on the machine frame and comprising a first lever arm (5') carrying the counter-pressure roller and a second lever arm (5") carrying the counter-pressure stopper (3), and which can be swivelled back and forth between two extreme positions by means of a preferably pneumatically or electromechanically operated actuating mechanism (4), such that in one extreme position the counter-pressure roller (11) is pressed against the drive roller (1) while the counter-pressure stopper (3) is raised and in the other extreme position the counter-pressure stopper (3) is pressed against the stopper (2) while the counter-pressure roller (11) is raised, characterised in that the advancing portion (8') of the label roll located in front of the dispensing edge (24) and the reversing portion (8") of the label roll located behind the dispensing edge (24) are passed together between the stopper (2) and the counter-pressure stopper (3), with the result that the advancing portion (8') and the reversing portion (8") of the label roll are jointly wedged between the stopper (3) and the counter-pressure stopper (2) while the counter-pressure roller (11) is raised.

Description

Die Erfindung betrifft einen Transport- und Brems­mechanismus in einer Etikettiervorrichtung der im Ober­begriff des Anspruchs 1 angegebenen Gattung. Mit Hilfe des Transport- und Bremsmechanismus wird ein Selbstklebe­etiketten tragendes Etikettenband schrittweise unter Freigabe eines Selbstklebeetiketts über eine Spendekante gezogen und in den Zwischenphasen angehalten.The invention relates to a transport and braking mechanism in a labeling device of the type specified in the preamble of claim 1. With the help of the transport and braking mechanism, a label tape carrying self-adhesive labels is gradually pulled over a dispensing edge with the release of a self-adhesive label and stopped in the intermediate phases.

Bei einem bekannten Transport- und Bremsmechanismus dieser Art (DE-PS 24 32 501) ist in Vorschubrichtung hinter der Spendekante eine gestellfest gelagerte, kon­tinuierlich angetriebene Antriebsrolle und eine gegen die Antriebsrolle unter Zwischenklemmen des leeren Rück­laufteils des Etikettenbandes andrückbare Gegendruckrolle sowie eine in Vorschubrichtung vor der Antriebsrolle angeordnete, aus einem gestellfesten Stopper und einem gegen diesen unter Zwischenklemmen des Etikettenbands andrückbaren Gegendruckstopper bestehende Bandbremse vorgesehen. Weiter ist dort ein Hebel gestellfest ge­lagert, der einen ersten, die Gegendruckrolle tragenden Hebelarm und einen zweiten den Gegendruckstopper tragen­den Hebelarm aufweist und der über einen pneumatisch auslösbaren Betätigungsmechanismus so zwischen zwei Endstellungen hin- und herschwenkbar ist, daß in der einen Endstellung die Gegendruckrolle bei abgehobenem Gegendruckstopper gegen die Antriebsrolle und in der anderen Endstellung der Gegendruckstopper bei abgehobener Gegendruckrolle gegen den Stopper gepreßt wird. Die Bandbremse mit Stopper und Gegendruckstopper ist dort in Vorschubrichtung vor der Spendekante angeordnet, wirkt also auf den mit den Selbstklebeetiketten be­ stückten Vorlaufteil des Etikettenbands. Um auf der relativ langen Strecke zwischen Bandbremse und Antriebs­rolle im angehaltenen Zustand ein Durchhängen des Eti­kettenbands zu vermeiden, wird sowohl die Antriebsrolle als auch die Gegendruckrolle vom Rücklaufteil des Eti­kettenbands teilweise umschlungen, so daß auch bei abge­hobener Gegendruckrolle eine Zugkraft durch die schleifende Antriebsrolle auf das Etikettenband ausgeübt wird. Je nach Oberflächenbeschaffenheit des Etiketten­bands führt dies beim Stillstand zu einem mehr oder weniger starken Abrieb auf dem Etikettenband und auf der Oberfläche der Antriebsrolle, so daß die Gefahr einer Bandüberdehnung oder gar eines Bandrisses einer­seits und eines vorzeitigen Verschleißes der Rollenober­fläche andererseits besteht.In a known transport and braking mechanism of this type (DE-PS 24 32 501) is in the feed direction behind the dispensing edge a permanently fixed drive roller mounted on the frame and a counter-pressure roller which can be pressed against the drive roller with intermediate clamping of the empty return part of the label tape and one in the feed direction before Drive roller arranged, provided from a frame-fixed stopper and a counterpressure against which it can be pressed against it with intermediate clamps of the label tape. Furthermore, there is a lever fixed to the frame, which has a first lever arm carrying the counterpressure roller and a second lever arm carrying the counterpressure stopper and which can be pivoted back and forth between two end positions via a pneumatically triggerable actuating mechanism such that in one end position the counterpressure roller when lifted off Counter pressure stopper is pressed against the drive roller and in the other end position the counter pressure stopper is pressed against the stopper when the counter pressure roller is lifted off. The tape brake with stopper and counter pressure stopper is arranged in the feed direction in front of the dispensing edge, so it acts on the self-adhesive label cut the leading part of the label tape. In order to avoid sagging of the label tape on the relatively long route between the tape brake and the drive roller when stopped, both the drive roller and the counter pressure roller are partially wrapped around by the return part of the label tape, so that even when the counter pressure roller is lifted off, a pulling force by the sliding drive roller on the label tape is exercised. Depending on the surface quality of the label tape, this leads to a more or less severe abrasion on the label tape and on the surface of the drive roller when it is at a standstill, so that there is a risk of tape overstretching or even a tape break on the one hand and premature wear of the roll surface on the other.

Der Erfindung liegt die Aufgabe zugrunde, den bekannten Transport- und Bremsmechanismus der eingangs angegebenen Art dahingehend zu verbessern, daß der Verschleiß im Bereich der Antriebsrolle verringert und die Gefahr einer Banduberdehnung oder gar eines Bandrisses auch bei längeren Stillstandszeiten vermieden wird.The invention has for its object to improve the known transport and braking mechanism of the type mentioned in such a way that the wear in the area of the drive roller is reduced and the risk of belt overstretching or even a belt breakage is avoided even during longer downtimes.

Zur Lösung dieser Aufgabe wird die im Patentanspruch 1 angegebene Merkmalskombination vorgeschlagen. Weitere vorteilhafte Ausgestaltungen und Weiterbildungen des Erfindungsgedankens ergeben sich aus den abhängigen Ansprüchen.To achieve this object, the combination of features specified in claim 1 is proposed. Further advantageous refinements and developments of the inventive concept result from the dependent claims.

Die Erfindung geht von dem Gedanken aus, daß bei einer Anordnung des Stoppers in Vorschubrichtung hinter der Spendekante in der Nähe der Antriebsrolle eine Um­ schlingung der Antriebsrolle und der Gegendruckrolle entbehrlich ist, so daß das Etikettenband im angehalte­nen Zustand von der Antriebsrolle abgehoben und dadurch ein Abrieb auf dem Etikettenband und der Antriebsrolle vermieden werden kann. Gemäß der Erfindung wird dement­sprechend vorgeschlagen, daß der Stopper in Vorschub­richtung hinter der Spendekante in der Nähe der Antriebs­rolle angeordnet ist, und daß das Etikettenband durch die Gegendruckrolle tangential und umschlingungsfrei gegen die Antriebsrolle andrückbar und im angehaltenen Zustand von dieser abgehoben ist. Eine Straffung des Etikettenbandes im Bereich der Spendekante läßt sich hierbei dadurch erreichen, daß die Vorratsrolle des Etikettenbandes eine einstellbare Lagerreibung aufweist und/oder daß im Bereich vor der Spendekante eine Bürste oder dergleichen Bremselement gegen den Bandvorlauf anliegt.The invention is based on the idea that an arrangement of the stopper in the feed direction behind the dispensing edge in the vicinity of the drive roller Looping of the drive roller and the counter-pressure roller is unnecessary, so that the label tape can be lifted from the drive roller in the stopped state and thereby abrasion on the label tape and the drive roller can be avoided. According to the invention it is accordingly proposed that the stopper is arranged in the feed direction behind the dispensing edge near the drive roller, and that the label tape can be pressed tangentially and without wrap against the drive roller and lifted from it in the stopped state. A tightening of the label tape in the area of the dispensing edge can be achieved in that the supply roll of the label tape has an adjustable bearing friction and / or that in the area in front of the dispensing edge a brush or similar braking element rests against the tape advance.

Eine weitere Verbesserung in dieser Hinsicht kann da­durch erzielt werden, daß die Bandbremse einen an einem dritten Hebelarm angeordneten zweiten Gegendruckstopper aufweist, der bei abgehobener Gegendruckrolle unter Zwischenklemmen des Vorlaufteils des Etikettenbands gegen einen in Vorschubrichtung vor der Spendekante angeordneten zweiten gestellfesten Stopper anpreßbar ist.A further improvement in this regard can be achieved in that the tape brake has a second counterpressure stop arranged on a third lever arm, which can be pressed against a second stopper fixed to the frame in the advancing direction before the dispensing edge when the counterpressure roller is lifted off by interposing the feed part of the label tape.

Gemäß einer weiteren bevorzugten Ausgestaltung der Er­findung wird der vor der Spendekante befindliche, mit den Selbstklebeetiketten bestückte Vorlaufteil des Eti­kettenbands durch den Bereich zwischen Stopper und Gegen­druckstopper hindurchgeführt, so daß er im angehaltenen Zustand gemeinsam mit dem hinter der Spendekante be­ findlichen Rücklaufteil des Etikettenbands zwischen Stopper und Gegendruckstopper eingeklemmt wird.According to a further preferred embodiment of the invention, the leading part of the label tape located in front of the dispensing edge and equipped with the self-adhesive labels is passed through the area between the stopper and the counterpressure stopper, so that it be in the stopped state together with that behind the dispensing edge sensitive return part of the label tape is clamped between the stopper and counter pressure stopper.

Bei den beiden letztgenannten Ausgestaltungen ist es möglich, den Vorlaufteil des Etikettenbands im ange­haltenen Zustand einer Zugbelastung auszusetzen, ohne daß es zu einer Lockerung des Etikettenbands im Bereich der Spendekante kommt. Solche Zugbelastungen treten beispielsweise bei einer Prägebearbeitung der Etiketten durch den zurückziehenden und noch an den Etiketten haftenden Prägestempel auf. Auf eine verschleißanfällige Andrückbürste im Bereich der Spendekante kann hier ver­zichtet werden.In the latter two configurations, it is possible to subject the leading part of the label tape to a tensile load in the stopped state without the label tape loosening in the area of the dispensing edge. Such tensile loads occur, for example, when the labels are embossed by the retracting embossing stamp which is still adhering to the labels. A pressure-sensitive pressure brush in the area of the dispensing edge can be dispensed with here.

The invention is explained in more detail below on the basis of the exemplary embodiments shown schematically in the drawing. Show it

Der in den Figuren in verschiedenen Ausführunsbeispielen dargestellte Transport- und Bremsmechanismus ist für eine Etikettiervorrichtung bestimmt, in welcher der mit Selbstklebeetiketten 15 bestückte Vorlaufteil 8' eines Etikettenbands von einer nicht dargestellten Vor­ratsrolle in Richtung der Pfeile 20 abgezogen und über eine nicht gezeigte Spendekante unter Freigabe der Selbstklebeetiketten 15 geführt wird. Hinter der Spende­kante gelangt der leere Rücklaufteil 8" des Etiketten­bands in Vorschubrichtung zunächst durch eine aus einem gestellfesten Stopper 2 und einem Gegendruckstopoer 3 bestehende Bandbremse und anschließend an der in Richtung des Pfeils 22 kontinuierlich mit konstanter Drehzahl angetriebenen, gestellfest gelagerten Antriebs­rolle vorbei zu einer nicht dargestellten Aufwickelrolle. Die Drehzahl der Antriebsrolle 1 wird über einen regel­baren Elektromotor oder über ein Regelgetriebe einge­stellt.The transport and braking mechanism shown in the figures in various exemplary embodiments is intended for a labeling device in which the leading part 8 'of a label tape equipped with self-adhesive labels 15 is pulled off a supply roll (not shown) in the direction of the arrows 20 and is released via a dispensing edge, not shown, with the release of the Self-adhesive labels 15 is performed. Behind the dispensing edge, the empty return part 8 "of the label tape in the feed direction first passes through a tape brake consisting of a stopper 2 fixed to the frame and a counterpressure stopper 3 and then past the drive roller, which is continuously driven at constant speed in the direction of arrow 22, to a drive roller not shown The speed of the drive roller 1 is set via a controllable electric motor or via a regulating gear.

Der Transport des Etikettenbands 8',8" in Richtung der Pfeile 20 erfolgt durch die Antriebsrolle 1 dadurch, daß der Rücklauf 8" durch eine Gegendruckrolle 11 gegen die Umfangsfläche der Antriebsrolle 1 gepreßt wird.The transport of the label tape 8 ', 8 "in the direction of the arrows 20 is carried out by the drive roller 1 in that the return 8" is pressed by a counter-pressure roller 11 against the peripheral surface of the drive roller 1.

Die Gegendruckrolle ist auf einem ersten Hebelarm 5' eines um die gestellfeste Achse 10 schwenkbaren Kipp­hebels gelagert, auf dessen zweiten Hebelarm 5" der Gegendruckstopper 3 angeordnet ist. Die Betätigung des Hebels 5',5" erfolgt mit Hilfe eines pneumatisch oder elektromechanisch auslösbaren Betätigungsmechanismus 4, der über eine Steuerstange 7 und einen am einen Ende an seinem Gelenk 9 mit der Steuerstange 7 und am anderen Ende starr mit dem zweiarmigen Hebel 5',5" verbundenen Steuerhebel 6 zwischen zwei Endstellungen hin- und her­schwenkbar ist. In der einen Endstellung ist die Gegen­druckrolle 11 bei abgehobenem Gegendruckstopper 3 unter Zwischenklemmen des Rücklaufs 8" gegen die Antriebs­rolle gepreßt (Fig. 1), während in der anderen End­stellung der Gegendruckstopper 3 bei abgehobener Gegen­druckrolle 11 unter Zwischenklemmen des Rückläufs 8" gegen den Stopper 2 gepreßt ist (Fig. 2). Der Rücklauf 8" ist unter einem flachen Winkel über die Gegenandruck­rolle 11 geführt, so daß er zusammen mit der Gegenan­druckrolle 11 von der Antriebsrolle 1 abgehoben wird.The counterpressure roller is mounted on a first lever arm 5 'of a rocker arm pivotable about the axis 10 fixed to the frame, on the second lever arm 5 "of which the counterpressure stopper 3 is arranged. The actuation of the lever 5', 5" takes place with the aid of a pneumatically or electromechanically actuatable actuating mechanism 4 which is connected via a control rod 7 and one at one end at its hinge 9 to the control rod 7 and at the other end rigidly to the two-armed lever 5 ', 5 " Control lever 6 can be pivoted back and forth between two end positions. In one end position the counter pressure roller 11 is pressed against the drive roller with the counter pressure stop 3 lifted off, with intermediate clamps of the return 8 ″ (FIG. 1), while in the other end position the counter pressure stopper 3 is lifted against the stopper 2 with the counter pressure roller 11 lifted off, intermediate clamps of the return 8 ” is pressed (Fig. 2). The return 8 "is guided at a flat angle over the counter-pressure roller 11 so that it is lifted off the drive roller 1 together with the counter-pressure roller 11.

In Figur 3 ist eine konstruktive Ausführungsförm des in den Figuren 1 und 2 im Funktionsschema dargestellten Transport- und Bremsmechanismus gezeigt.FIG. 3 shows a constructive embodiment of the transport and braking mechanism shown in the functional diagram in FIGS. 1 and 2.

Bei dem in Figur 4 in einem Funktionsschema dargestellten abgewandelten Ausführungsbeispiel eines Transport- und Bremsmechanismus ist eine zusätzliche Bandbremse im Bereich des Bandvorlaufs 8' angeordnet, die einen ge­stellfesten Stopper 12 und einen auf einem mit dem Hebel 5',5" starr verbundenen dritten Hebelarm 14 angeordneten Gegendruckstopper 13 aufweist. Der Bandvorlauf 8' ist hierbei zwischen Stopper 12 und Gegendruckstopper 13 hindurchgeführt. In der gezeigten Antriebsstellung sind bei angedrückter Gegendruckrolle 11 beide Gegendruck­stopper 3 und 13 vom Etikettenband 8",8' abgehoben während in der Bremsstellung die Gegendruckstopper 3 und 13 bei abgehobener Gegendruckrolle 11 gemeinsam gegen den jeweiligen Stopper 2 und 12 gepreßt werden. Eine aus nachgiebigem Material, wie beispielsweise Gummi, bestehende Bremsschicht 18 auf Stopper und Gegendruck­stopper sorgt für eine zuverlässige und gleichmäßige Abbremsung der beiden Bandteile 8',8".In the modified exemplary embodiment of a transport and braking mechanism shown in FIG. 4 in a functional diagram, an additional band brake is arranged in the region of the band advance 8 ′, which has a stop 12 fixed to the frame and a third lever arm 14 rigidly connected to the lever 5 ′, 5 ″ arranged counter pressure stop 13. The tape feed 8 'is passed between the stop 12 and the counter pressure stop 13. In the drive position shown, with the counter pressure roller 11 pressed on, both counter pressure stops 3 and 13 are lifted off the label tape 8 ", 8' while in the braking position the counter pressure stops 3 and 13 when the counter-pressure roller 11 is lifted, they are pressed together against the respective stoppers 2 and 12. A brake layer 18 on the stopper and counter-pressure stop made of resilient material, such as rubber, ensures reliable and uniform braking of the two band parts 8 ', 8 ".

Bei dem in Figur 5 gezeigten abgewandelten Ausführungs­beispiel ist auch der Vorlaufteil 8' des Etikettenbandes durch die Bandbremse 2,3 hindurchgeführt. Die Umlenk­rollen 16 und 17 sorgen dafür, daß der Vorlaufteil 8' und der Rücklaufteil 8" des Etikettenbandes im Bereich zwischen Stopper 2 und Gegendruckstopper 3 im wesent­lichen parallel zueinander ausgerichtet sind. Beim An­pressen des Gegendruckstoppers 3 gegen den Stopper 2 werden somit beide Bandteile 8' und 8" gemeinsam festge­halten.In the modified exemplary embodiment shown in FIG. 5, the leading part 8 'of the label tape is also passed through the tape brake 2, 3. The deflection rollers 16 and 17 ensure that the feed part 8 'and the return part 8 "of the label tape are aligned essentially parallel to one another in the area between the stopper 2 and the counterpressure stopper 3. When the counterpressure stopper 3 is pressed against the stopper 2, both tape parts 8' are thus and 8 "held together.

Das Ausführungsbeispiel nach Figur 6 entspricht weitgehend dem nach Figur 5, bei welchem der Vorlaufteil 8' und der Rücklaufteil 8" gemeinsam durch eine einzige, aus Stopper 2 und Gegendruckstopper 3 bestehende Bandbremse hindurchgeführt sind. Es ist lediglich dahingehend abgewandelt, daß die Umlenkrolle 17 entfällt und somit der Vorlaufteil 8' und der Rücklaufteil 8" des Etikettenbands auf der gesamten Strecke zwischen Umlenkrolle 16, Bandbremse 2,3 und Spendekante 24 in kleinem Abstand voneinander im wesentlichen parallel zueinander ausgerichtet sind. Die Spendekante 24 ist am freien Ende eines dünnwandigen Tisches 26 angeordnet, der gleichzeitig als Widerlager für ein nicht dargestelltes, auf die Selbstklebeetiketten von oben her einwirkendes Druck- oder Prägeaggregat ausgebildet ist. Das Etikettenband wird unter Umlenkung um 180° so über die Spendekante 24 gezogen, daß die Selbstklebeetiketten 15 sich aufgrund ihrer Eigensteifigkeit vom Band ablösen.The embodiment according to FIG. 6 largely corresponds to that according to FIG. 5, in which the forward part 8 'and the return part 8 "are passed together through a single band brake consisting of stopper 2 and counterpressure stopper 3. It is merely modified in that the deflection roller 17 is omitted and thus the forward part 8 'and the return part 8 "of the label tape are oriented essentially parallel to one another at a small distance from one another over the entire distance between the deflection roller 16, band brake 2, 3 and dispensing edge 24. The dispensing edge 24 is arranged at the free end of a thin-walled table 26, which is simultaneously designed as an abutment for a printing or embossing unit, not shown, which acts on the self-adhesive labels from above. The label tape is pulled over the dispensing edge 24 under deflection by 180 ° in such a way that the self-adhesive labels 15 detach from the tape due to their inherent rigidity.
