Title
(DE) ETIKETTENEINLEGEVERFAHREN UND -VORRICHTUNG
(EN) LABEL-INSERTING METHOD AND DEVICE
(FR) PROCEDE ET DISPOSITIF POUR L'INSERTION D'ETIQUETTES
Abstract
(DE)
Die Erfindung bezieht sich auf ein Verfahren zum Bereitstellen von mindestens einem, in eine Formhälfte (36, 46, 47) eines Werkzeugs (34) einer Kunststoffverarbeitungsmaschine, insbesondere Spritzgussmaschine (2, 45) oder Tiefziehmaschine, einlegbaren Einlegeetikett (29) am Werkzeug (34) der Maschine. Bei diesem Verfahren wird aus Etikettenbandmaterial (22) durch eine im wesentlichen aus einer Stanzplatte (17) und einem Schnittwerkzeug (19) bestehenden Stanzvorrichtung (1) Einlegeetiketts (29) herausgestanzt. Diese Einlegeetiketts (29) werden durch einen zur Stanzvorrichtung (1) zugehörigen Träger zum Werkzeug (34) der Maschine (2, 45) überführt und zum Einlegen in dieses abgegeben. Bisher stellt es ein grosses Problem dar, dieses Überführen mit einer ausreichend präzisen und knitterfreien Positionierung des Einlegeetiketts (29) durchzuführen. Dieses Problem wird dadurch beseitigt, dass die Einlegeetiketts (29) nach dem Stanzvorgang von der im wesentlichen quer zur Stanzrichtung verschiebbaren, als Träger ausgebildeten Stanzplatte (17) gehalten und zum Werkzeug (34) der Maschine (2, 45) überführt werden. Des weiteren bezieht sich die vorliegende Erfindung auf eine Vorrichtung zum Durchführen des Verfahrens.

(EN)
The invention concerns a method of preparing on the tool (34) of a machine at least one insert label (29) which can be inserted in a mould half (36, 46, 47) of the tool (34) of a plastics processing machine, in particular an injection moulding machine (2, 45) or deep-drawing machine. In this method, insert labels (29) are stamped out of label strip material (22) by a stamping device (1) substantially comprising a stamping plate (17) and a cutting tool (19). These insert labels (29) are conveyed by a carrier, which is associated with the stamping device (1), to the tool (34) of the machine (2, 45) and delivered for insertion in the tool. Hitherto, it was very difficult to transfer the insert labels (29) with sufficient precision and position them without creases. This difficulty is overcome in that, after being stamped, the insert label (29) is held and conveyed to the tool (34) of the machine (2, 45) by the stamping plate (17), which is in the form of a carrier and can be displaced substantially transversely to the stamping direction. The present invention further concerns a device for carrying out the method.

(FR)
L'invention se rapporte à un procédé pour la mise en place sur un outil (34) d'une machine, d'au moins une étiquette d'insertion (29) pouvant être insérée dans un demi-moule (36, 46, 47) d'un outil (34) d'une machine de transformation de matière plastique, en particulier, d'une machine de moulage par injection (2, 45) ou d'une machine d'emboutissage profond. Dans ce procédé, des étiquettes d'insertion (29) sont découpées à partir d'un matériau en bande (22) au moyen d'un dispositif de poinçonnage (1) comprenant essentiellement une plaque de poinçonnage (17) et un outil à découper (19). Les étiquettes (29) sont transportées, au moyen d'un support associé au dispositif de poinçonnage (1), à l'outil (34) de la machine (2, 45) et délivrées en vue de leur insertion dans cet outil. Dans les dispositifs connus jusqu'à présent, on ne peut effectuer le transfert des étiquettes (29) en les positionnant avec une précision suffisante et sans les froisser. L'invention permet de remédier à ces inconvénients grâce au fait que les étiquettes d'insertion (29) sont maintenues, après découpage, par la plaque de poinçonnage (17) réalisée sous la forme d'un support déplaçable sensiblement perpendiculairement à la direction de découpage et sont transférées à l'outil (34) de la machine (2, 45). L'invention concerne en outre un dispositif pour la mise en ÷uvre de ce procédé.
