Abstract

The continuous label strip (2) is fed over a sharp edge (4) which lifts each label from the strip. A cutter removes the label and a stamp (7) holds the label by suction. The stamp is pressed down onto the item and transfers the label securely onto the item. The labelling machine is adjustable to operate with labels of different sizes and with different spacings on the backing strip. A stepping motor (9) drives the reciprocating system, with a rack-and-pinion drive to set the relative movements. The cutter is positioned in front of the dispensing edge for lifting the labels from the strip and provides minimum damage risk to the strip.

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Spenden und Ablegen von selbstklebenden Flächengebilden nach dem Oberbegriff des Patentanspruches 1 bzw. dem Oberbegriff des Patentanspruches 4.The invention relates to a method and a device for dispensing and depositing self-adhesive fabrics according to the preamble of claim 1 and the preamble of claim 4.

Bei derartigen, z. B. aus der DE-OS 40 20 847 bekannten Verfahren und Vorrichtungen werden selbstklebende Etiketten, die mit der Klebschicht auf einem Trägerband haften, vom Trägerband zu einer Übergabestation befördert, in der sie vom Trägerband abgenommen werden, indem das Trägerband in einem spitzen Winkel um eine Spendekante geführt und die Etiketten von einer mit Ansaugöffnungen versehenen Stempelplatte erfaßt werden, welche die Etiketten auf einem Objekt, z. B. einer Warenverpackung, ablegt. Hierbei ist es nachteilig, daß die Etiketten als vorgestanzte Gebilde auf dem Trägerband vorhanden sind, so daß abhängig von der jeweils benötigten Größe und Anzahl der Etiketten das Trägerband gewechselt werden muß. Dies bedingt neben Stillstandzeiten der Vorrichtungen einen erheblichen Lagerraum für Transportbänder mit unterschiedlichen Etiketten.In such, e.g. B. from DE-OS 40 20 847 known methods and devices are self-adhesive labels that adhere to the adhesive layer on a carrier tape, transported from the carrier tape to a transfer station, in which they are removed from the carrier tape by the carrier tape at an acute angle guided a dispensing edge and the labels are detected by a stamp plate provided with suction openings, which the labels on an object, for. B. a goods packaging. It is disadvantageous here that the labels are present as pre-punched structures on the carrier tape, so that the carrier tape must be changed depending on the size and number of labels required in each case. In addition to downtimes of the devices, this requires one considerable storage space for conveyor belts with different labels.

Aufgabe der Erfindung ist es nun, ein Verfahren und eine Vorrichtung zu schaffen, womit durch Änderungen in der Gestalt der abzugebenden Etiketten bedingte Stillstandzeiten auf ein Minimum reduziert werden.The object of the invention is now to provide a method and a device with which downtimes caused by changes in the shape of the labels to be dispensed are reduced to a minimum.

Diese Aufgabe wird gemäß der Erfindung ausgehend von einem Verfahren der eingangs beschriebenen Gattung gemäß Patentanspruch 1 dadurch gelöst, daß jedes Flächengebilde unmittelbar vor dem Ablösen vom Trägerband von einem endlosen Materialstreifen auf dem Trägerband abgetrennt wird.This object is achieved according to the invention on the basis of a method of the type described at the beginning according to claim 1 in that each fabric is separated from an endless strip of material on the carrier tape immediately before it is detached from the carrier tape.

Mit dem erfindungsgemäßen Abtrennen jedes Flächengebildes von einem auf dem Trägerband anhaftenden endlosen Materialstreifen unmittelbar vor dessen Ablösen vom Trägerband sowie dessen Überführen an ein Objekt wird es ausschließlich durch Einstellen des Trennpunktes, was zweckmäßigerweise beim schrittweisen Umlenken des Trägerbandes zum Lösen des Flächengebildes vom Trägerband durch Verändern der Schrittlänge erfolgt, auf einfache Weise möglich, von einem endlosen Materialstreifen unterschiedlich lange Flächengebilde abzutrennen und zu spenden. Es entfällt durch die Maßnahmen nach der Erfindung nicht nur das Stillstandzeiten verursachende Austauschen von Trägerbändern mit unterschiedlichen Flächengebilden. Es werden auch keine Werkzeuge benötigt, um Trägerbänder mit Flächengebilden unterschiedlicher Länge zu fertigen.With the inventive separation of each fabric from an endless strip of material adhering to the carrier tape immediately before its detachment from the carrier tape and its transfer to an object, it becomes exclusively by setting the separation point, which is expedient when the carrier tape is gradually deflected to Detaching the fabric from the carrier tape by changing the stride length is easily possible to separate and donate fabrics of different lengths from an endless strip of material. The measures according to the invention not only eliminate the need to replace carrier tapes with different flat structures which cause downtimes. No tools are required to produce carrier tapes with flat structures of different lengths.

Eine Vorrichtung gemäß dem Oberbegriff des Anspruches 4 zur Durchführung des Verfahrens nach der Erfindung ist dadurch ein vorzugsweise als Hack- oder Schlagmesser ausgebildetes Schmiedewerk gekennzeichnet, das von einem auf dem Trägerband haftenden endlosen Materialstreifen ein Flächengebilde unmittelbar vor dessen Übergabe an den Stempel abtrennt.A device according to the preamble of claim 4 for carrying out the method according to the invention is characterized by a forge, preferably designed as a chopper or percussion knife, which separates a sheet of material from an endless strip of material adhering to the carrier tape immediately before its transfer to the stamp.

Diese neue Vorrichtung ermöglicht die Durchführung des erfindungsgemäßen Verfahrens zum Spenden und Ablegen von selbstklebenden Flächengebilden durch die Anordnung des Schneidwerkes vor der Spendekante für das Flächengebilde mit einfachen Mitteln. Hierbei wird durch die bevorzugte Ausgestaltung des Schneidwerkes als Schlag- oder Hackmesser, dessen Klinge zweckmäßigerweise von einem Kniehebelsystem angetrieben wird, nicht nur eine hohe Arbeitsgeschwindigkeit des Schneidwerkes erzielt, sondern auch eine präzise Einstellung der Schnitt-Tiefe ohne großen Aufwand erreicht; denn zum störungsfreien Betrieb der Vorrichtung muß verhindert werden, daß beim Abtrennen eines Flächengebildes vom Materialstreifen das Trägerband beschädigt wird.This new device enables the method according to the invention for dispensing and depositing self-adhesive flat structures to be carried out by the arrangement the cutting unit in front of the dispensing edge for the fabric with simple means. Here, the preferred design of the cutting mechanism as a chopper or cleaver, the blade of which is expediently driven by a toggle lever system, not only achieves a high working speed of the cutting mechanism, but also achieves precise adjustment of the cutting depth without great effort; because for trouble-free operation of the device it must be prevented that the carrier tape is damaged when a sheet is separated from the material strip.

Bei der dargestellten Vorrichtung wird ein Trägerband 1, auf dem ein endloser Materialstreifen 2 (Fig. 2a bis 2c) mit einem Haftkleber befestigt ist, von einer Vorratsrolle 3 abgezogen und um eine Spendekante 4 geführt, an der ein von der Klinge 5 eines Schneidwerkes vom Materialstreifen 2 abgetrenntes Flächengebilde 6 z. B. ein Etikett vom Träger band 1 abgelöst sowie an einen Stempel 7 übergeben wird. Das Trägerband 1 wird anschließend auf eine Abzugsrolle 8 aufgewickelt. Der Transport des Trägerbandes 1 wird von einem Schrittmotor 9 über eine mit dem Trägerband 1 in Wirkverbindung stehende Antriebsrolle 10 bewirkt.In the device shown, a carrier tape 1, on which an endless strip of material 2 (FIGS. 2a to 2c) is fastened with a pressure sensitive adhesive, is pulled off a supply roll 3 and guided around a dispensing edge 4, on which one of the blades 5 of a cutting unit from Strips of material 2 separated fabric 6 z. B. a label detached from the carrier tape 1 and passed to a stamp 7. The carrier tape 1 is then wound onto a take-off roll 8. The transport of the carrier tape 1 is effected by a stepper motor 9 via a drive roller 10 which is operatively connected to the carrier tape 1.

Die Antriebsrolle 10 treibt weiter eine Welle 11 an, auf der ein Zahnrad 12 mit einer Freilauf- bzw. Klemmkupplung (nicht dargestellt) gelagert ist. Mit dem Zahnrad 12 kämmt eine Zahnstange 13, die am Stempel 7 angreift und denselben in Vorschubrichtung des Trägerbandes 1 vor dessen Umlenkung an der Spendekante 4 verstellt.The drive roller 10 further drives a shaft 11 on which a gear 12 with a one-way clutch or clamping clutch (not shown) is mounted. With the gear 12 meshes a rack 13 which engages the punch 7 and the same is adjusted in the feed direction of the carrier tape 1 before it is deflected at the dispensing edge 4.

Zum Anbringen des vom Materialstreifen 2 abgetrennten und am Stempel 7 durch Unterdruck gehaltenes Flächengebildes 6 an einem Objekt 14 wird der Stempel 7 auf dieses Objekt 14 abgesenkt und der Unterdruck aufgehoben, so daß das Flächengebilde 6 mit seiner Klebschicht am Objekt 14 haftet.To attach the sheet 6 separated from the material strip 2 and held on the stamp 7 by a vacuum, the stamp 7 is lowered onto this object 14 and the vacuum is released so that the sheet 6 adheres to the object 14 with its adhesive layer.

Das Schneidwerk (Fig. 2a bis 2c) umfaßt einen Amboß 15, an dem zugleich die Spendekante 4 ausgebildet ist und der das Widerlager für die an einem Messerhalter 16 befestigte Klinge 5 bildet. Der Messerhalter 16 ist über eine nicht dargestellte Stange schwingend am Rahmen des Schneidwerkes gehalten. Am der Schneide der Klinge 5 gegenüberliegenden Ende des Messerhalters 16 greift ein Schenkel 17 eines Kniehebels 18 an, dessen anderer Schenkel 19 Teil eines um einen Bolzen 20 schwenkbaren Winkelstückes 21 ist. Das freie Ende des anderen Teiles 22 des Winkelstückes 21 ist mit der Kolbenstange 23 eines Pneumatikzylinders (nicht gezeigt) verbunden.The cutter (Fig. 2a to 2c) comprises an anvil 15, on which the dispensing edge 4 is also formed and which forms the abutment for the blade 5 attached to a knife holder 16. The knife holder 16 is held in a swinging manner on the frame of the cutting mechanism via a rod (not shown). On the edge of the blade 5 opposite the end of the knife holder 16, one leg 17 of a toggle lever 18 engages, the other leg 19 of which is part of an angle piece 21 which can be pivoted about a bolt 20. The free end of the other part 22 of the angle piece 21 is one with the piston rod 23 Pneumatic cylinder (not shown) connected.

Im folgenden wird noch das Zusammenwirken der einzelnen Elemente der beschriebenen Vorrichtung beim Spenden und Ablegen von Flächengebilden erläutert:
Das schrittweise von der Vorratsrolle 3 mit dem Schrittmotor 9 abgezogene Trägerband 1 mit anhaftenden Materialstreifen 2 wird an der Klinge 5 vorbei über den Amboß 15 und unter Umbiegen an der Spendekante 4 zur Abzugsrolle 8 geführt. Dabei befinden sich die Klinge 5 und der Stempel 7 in der in Fig. 1a gezeigten Warteposition.The interaction of the individual elements of the device described when dispensing and depositing flat structures is explained below:
The carrier tape 1 with adhering material strips 2, which is gradually withdrawn from the supply roll 3 with the stepping motor 9, is guided past the blade 5 over the anvil 15 and with bending at the dispensing edge 4 to the take-off roll 8. The blade 5 and the stamp 7 are in the waiting position shown in FIG. 1a.

Sobald eine durch die Schrittgröße vorbestimmte Länge des Materialtreifen 2 die Schneide der Klinge 5 passiert hat, wird der Stempel 7 auf den Materialstreifen 2 abgesenkt und trennt die Klinge 5 durch Anheben oder Absenken der Kolbenstange 23 des Pneumatikzylinders ein Flächengebilde 6 vom Materialstreifen 2 ab. Die Klinge 5 und der Stempel 7 nehmen dabei die in Fig. 1b bzw. Fig. 2b gezeigte Schneidstellung ein.As soon as a length of the material strip 2 predetermined by the step size has passed the cutting edge of the blade 5, the stamp 7 is lowered onto the material strip 2 and separates the blade 5 from the material strip 2 by lifting or lowering the piston rod 23 of the pneumatic cylinder. The blade 5 and the punch 7 assume the cutting position shown in Fig. 1b and Fig. 2b.

Nach dem Abschneiden eines Flächengebildes 6 vom Materialstreifen 2 wird nicht nur die Klinge 5 durch die Fortsetzung der den Schneidvorgang auslösenden Bewegung der Kolbenstange 23 angehoben (Fig. 2a oder Fig. 2c), sondern auch das Trägerband 1 vom Schrittmotor 9 eine Schrittlänge weiter gezogen. Dabei wird der Stempel 7 synchron zur Geschwindigkeit des Trägerbandes 1 von der Klinge 5 weg bewegt, indem das Zahnrad 12 die Zahnstange 13 entsprechend verstellt. Gleichzeitig wird der Abschnitt des Trägerbandes 1, der das von der Klinge 5 abgetrennte Flächengebilde trägt, um die Spendekante 4 gezogen, wodurch sich das Flächengebilde 6 vom Trägerband löst und an die Fläche des Stempels 7 übergeben wird, woran es durch Unterdruck gehalten wird. Sobald das Flächengebilde 6 vollständig vom Trägerband 1 abgezogen ist, wird der Stempel 7 noch weiter von der Klinge 5 entfernt, indem er von der nicht gezeigten, auf die Zahnstange 13 einwirkenden Kolbenstange eines weiteren Pneumatikzylinders gegen einen Anschlag in die Warteposition gemäß Fig. 1c bewegt wird. Dabei sind die Zahnstange 13 und das Zahnrad 12, das sich aufgrund der Freilaufkupplung auf der Welle 11 dreht, im Eingriff.After a sheet 6 has been cut off from the material strip 2, not only is the blade 5 raised by the continuation of the movement of the piston rod 23 which triggers the cutting process (FIG. 2a or FIG. 2c), but also the carrier tape 1 is pulled a step further by the stepping motor 9. The punch 7 is moved away from the blade 5 synchronously with the speed of the carrier tape 1 by the gear wheel 12 adjusting the rack 13 accordingly. At the same time, the portion of the carrier tape 1, which carries the sheet separated from the blade 5, is drawn around the dispensing edge 4, whereby the sheet 6 detaches from the carrier tape and is transferred to the surface of the stamp 7, whereupon it is held by negative pressure. As soon as the fabric 6 has been completely removed from the carrier tape 1, the stamp 7 is removed even further from the blade 5 by moving a piston rod of another pneumatic cylinder, not shown, acting on the rack 13 against a stop into the waiting position according to FIG. 1c becomes. Here are the rack 13 and the gear 12, which due to the overrunning clutch the shaft 11 rotates, in engagement.

In der Warteposition nach Fig. 1c wird der Stempel 7 mit nicht näher dargestellten Pneumatikelementen auf ein Objekt 14 abgesenkt (Fig. 1d und Fig. 2c), auf dem das Flächengebilde 6 mit seiner Haftschicht anzuordnen ist, deren Klebkraft so groß ist, daß nach Aufheben des Unterdruckes am Stempel 7 das Flächengebilde 2 sicher am Objekt 14 haftet.In the waiting position according to FIG. 1c, the stamp 7 is lowered with pneumatic elements (not shown in more detail) onto an object 14 (FIGS. 1d and 2c) on which the flat structure 6 with its adhesive layer is to be arranged, the adhesive force of which is so great that after Removing the negative pressure on the stamp 7, the fabric 2 adheres securely to the object 14.

Nach dem Ablegen des Flächengebildes 2 auf dem Objekt 14 wird der Stempel 7 angehoben, danach der Eingriff zwischen Zahnrad 12 und Zahnstange 13 aufgehoben und anschließend die Zahnstange 13 zusammen mit dem Stempel 7 von dem auf die Zahnstange 13 einwirkenden Pneumatikzylinder in die Warteposition gemäß Fig. 1a zurückgestellt. In dieser Position wird der Eingriff zwischen Zahnrad 12 und Zahnstange 13 wieder her- und dadurch sichergestellt, daß die Zahnstange 13 zwischen der Warteposition des Stempels 7 gemäß Fig. 1a und dessen Ablegeposition gemäß Fig. 1d stets die gleiche Wegstrecke zurücklegt, die ein ganzzahliges Vielfaches der Zahnteilung des Zahnrades 12 ist und sich aus einem ersten Abschnitt, der der durch den Schrittmotor bewirkten Drehung des Zahnrades 12 und folglich der Länge des zu spendenden Flächengebildes 6 entspricht, sowie einem zweiten Abschnitt zusammensetzt, den die Zahnstange 13 beim Verstellen des Stempels 7 nach dem Ablösen des Flächengebildes 6 vom Trägerband 1 gegen den Anschlag in die Position gemäß Fig. 1c zurücklegt. Durch Starten des Schrittmotors 9 kann somit ein neues Flächengebilde 6 gespendet und abgelegt werden.After depositing the sheet 2 on the object 14, the stamp 7 is raised, then the engagement between the gear 12 and the rack 13 is released and then the rack 13 together with the stamp 7 from the pneumatic cylinder acting on the rack 13 into the waiting position according to FIG. 1a deferred. In this position, the engagement between the gear 12 and the rack 13 is restored and thereby ensured that the rack 13 always covers the same distance between the waiting position of the stamp 7 according to FIG. 1a and its storage position according to FIG. 1d, which is an integer multiple of the tooth pitch of the gear 12 and is composed of a first section, which corresponds to the rotation of the gear 12 caused by the stepper motor and consequently the length of the fabric 6 to be donated, and a second section, which the rack 13 during adjustment the stamp 7 after detaching the fabric 6 from the carrier tape 1 against the stop in the position shown in FIG. 1c. By starting the stepping motor 9, a new sheet 6 can thus be donated and deposited.

Hieraus wird zugleich ersichtlich, daß es außer einer Veränderung der Taktzeit des Schrittmotors 9 keiner weiteren Einstellarbeiten bedarf, um die Länge des mit der erfindungsgemäßen Vorrichtung zu spendenden Flächengebildes 6 den jeweiligen Erfordernissen anzupassen.From this it can also be seen that, apart from a change in the cycle time of the stepping motor 9, no further adjustment work is required in order to adapt the length of the fabric 6 to be dispensed with the device according to the invention to the respective requirements.

Die Erfindung ist nicht auf die dargestellte und beschriebene Ausführungsform begrenzt, sondern schließt für den Fachmann geläufige Abwandlungen ein. So kann zum Beispiel in Transportrichtung des Trägerbandes unmittelbar vor oder hinter der Klinge des Schneidwerkes eine Druckeinrichtung angeordnet werden, um die zu spendenden Flächengebilde mit Informationen zu versehen. Bei Flächengebilden aus weichen oder schaumartigen Stoffen kann der Stempel zusätzlich mit Nadeln oder anderen Steckmitteln ausgestattet sein, um das Halten dieser Flächengebilde am Stempel zu verbessern.The invention is not limited to the illustrated and described embodiment, but includes modifications familiar to those skilled in the art. For example, in the direction of transport of the carrier tape immediately before or a printing device can be arranged behind the blade of the cutting unit in order to provide the fabrics to be donated with information. In the case of fabrics made of soft or foam-like materials, the stamp can additionally be equipped with needles or other plug-in means in order to improve the holding of these fabrics on the stamp.
