Description

Gegenstand der Erfindung ist ein Etikettenspender für Nähmaschinen, der aufweist:

  • (a) eine Halterung für eine Etikettenband-Vorratstrommel;
  • (b) einen Schrittmotor zum abschnittsweisen Vorschieben des Etikettenbands;
  • (c) einen Lichtsensor zum Erfassen von Lesemarken auf dem Etikettenband;
  • (d) eine Klemmvorrichtung zum Einklemmen jeweils des vorderen Endbereichs des Etikettenbands;
  • (e) ein Messer zum Abschneiden jeweils eines mit seinem vorderen Endbereich eingeklemmten Etiketts von dem Etikettenband;
  • (f) eine Zuführvorrichtung zum Ergreifen des jeweiligen Etiketts und dessen Zuführung zu der Nähmaschine zum Annähen an ein Nähgut; und
  • (g) eine elektronische Steuerung für den Schrittmotor, die mit Daten über die jeweils anzunähenden Etiketten programmierbar ist und an die der Lichtsensor ange­schlossen ist.
The invention relates to a label dispenser for sewing machines, which comprises:
  • (a) a holder for a label tape supply drum;
  • (b) a stepper motor for feeding the label tape in sections;
  • (c) a light sensor for detecting bookmarks on the label tape;
  • (d) a clamping device for clamping each of the front end portion of the label tape;
  • (e) a knife for cutting a label pinched from the label tape with its front end portion;
  • (f) a feed device for gripping the respective label and feeding it to the sewing machine for sewing on a material to be sewn; and
  • (g) an electronic control for the stepper motor, which is programmable with data about the labels to be sewn on and to which the light sensor is connected.

Bei einem bekannten Etikettenspender für Nähmaschinen wird das Etikettenband mittels eines Asynchronmotors, der mit einer Bremse ausgestattet ist, abschnittsweise vorge­schoben. Ein Lichtsensor erfaßt Lesemarken auf dem Eti­kettenband und steuert aufgrund dessen den Betrieb des Asynchronmotors sowie das Abschneidmesser. Wenn von einer Art von Etiketten auf eine andere Art von Etiketten, ins­besondere Etiketten mit anderer Länge, übergegangen wird, müssen mechanische Anschläge des Etikettenspenders und die Position des Lichtsensors längs des Etikettenbands mühsam und genau neu eingestellt werden. Außerdem besteht keine völlige Sicherheit, daß die Etiketten nicht ver­kanten oder verrutschen.In a known label dispenser for sewing machines, the label tape is advanced in sections by means of an asynchronous motor which is equipped with a brake. A light sensor detects bookmarks on the label tape and controls the operation of the asynchronous motor and the cutting knife. When changing from one type of label to another type of label, in particular labels with a different length, mechanical stops of the label dispenser and the position of the light sensor along the label tape have to be readjusted laboriously and accurately. In addition, there is no complete certainty that the labels will not tilt or slip.

Bei dem erfindungsgemäßen Etikettenspender ist keine Neueinstellung beim Übergang auf andere Etiketten erfor­derlich. Der Lichtsensor kann fest angeordnet sein, ins­besondere in einem festen Abstand von der Messerkante. Die funktionserforderlichen Daten für die jeweils zu verarbeitenden Etiketten können in die elektronische Steuerung einprogammiert werden. Dabei handelt es sich vorzugsweise um Daten hinsichtlich der Etikettenlänge und der Position der Lesemarke auf den Etiketten. Das Vorschieben des Etikettenbands erfolgt durch den elek­tronisch gesteuerten Schrittmotor genauer als durch den Asynchronmotor mit Bremse. Die Etiketten können schneller und zuverlässiger verarbeitet werden.With the label dispenser according to the invention, no readjustment is required when changing to other labels. The light sensor can be fixed, in particular at a fixed distance from the knife edge. The functionally required data for the labels to be processed can be programmed into the electronic control. It is about preferably about data regarding the label length and the position of the reading mark on the labels. The electronically controlled stepper motor pushes the label tape forward more precisely than the asynchronous motor with brake. The labels can be processed faster and more reliably.

Bevorzugte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben und werden weiter unten genauer erläutert.Preferred developments of the invention are specified in the subclaims and are explained in more detail below.

Vorzugsweise ist der Etikettenspender so ausgebildet, daß er wahlweise sowohl ungefalzte Etiketten als auch gefalzte Etiketten zum Annähen an Nähgut bereitstellen kann. Im letzgenannten Fall kann man die Klemmvorrich­tung, mit der ggf. eine Blaseinheit zusammenarbeitet, auch als Falzeinrichtung bezeichnen.The label dispenser is preferably designed in such a way that it can optionally provide both unfolded labels and folded labels for sewing on material to be sewn. In the latter case, the clamping device, with which a blowing unit may cooperate, can also be referred to as a folding device.

Die elektronische Steuerung ist vorzugsweise derart programmierbar, daß sie nicht nur den Schrittmotor sondern auch weitere Funktionen steuert, insbesondere die Klemmvorrichtung bzw. Falzeinrichtung, ggf. die Blasein­heit, das Abschneidmesser etc. Mittels des erfindungsge­mäßen Etikettenspenders lassen sich die Etiketten unab­hängig von ihrer Länge ohne Gefahr des Verrutschens oder Verkantens immer genau mittig falzen.The electronic control is preferably programmable in such a way that it controls not only the stepping motor but also other functions, in particular the clamping device or folding device, possibly the blowing unit, the cutting knife, etc. By means of the label dispenser according to the invention, the labels can be put into danger regardless of their length of slipping or tilting always fold exactly in the middle.

Der Vorschub von Etiketten mit Hilfe des Schrittmotors und das Falzen der Etiketten sind gleichzeitig durchführ­bar. Ob dabei die Beschriftung der Etiketten dem Nähgut zugewandt oder abgewandt sein soll, spielt keine Rolle.The feed of labels with the help of the stepper motor and the folding of the labels can be carried out simultaneously. It does not matter whether the labeling of the labels should face or face the sewing material.

Die Erfindung wird beispielsweise anhand einer bevor­zugten Ausführungsform gemäß der Zeichnung näher erläu­tert.The invention is explained in more detail, for example, using a preferred embodiment according to the drawing.

  • Fig. 2 schematisch einen Längsschnitt durch die Falz­einrichtung des Etikettenspenders nach Fig. 1 in der in Fig. 3 angedeuteten Schnittebene A-A,
  • Fig. 3 eine Einzelheit der Falzeinrichtung gemäß der Fig. 2 und
  • Fig. 4 schematische Darstellung der Arbeitsweise der Falzeinrichtung gemäß der Fig. 2 in sechs Schritten a - f.
Show it:
  • 1 general view of a label dispenser attached to a sewing machine according to the invention,
  • 2 schematically shows a longitudinal section through the folding device of the label dispenser according to FIG. 1 in the sectional plane AA indicated in FIG. 3,
  • Fig. 3 shows a detail of the folding device according to FIGS. 2 and
  • FIG. 4 shows a schematic representation of the operation of the folding device according to FIG. 2 in six steps a - f.

In der Figur 1 ist ein erfindungsgemäßer Etikettenspender 1 mittels eines mehrere Freiheitsgrade aufweisenden Ge­stells 2 unmittelbar an der Rückseite einer Nähmaschine N angeordnet. An der Vorderseite der Nähmaschine N befindet sich eine bekannte, durch einen Schwenkantrieb As be­tätigbare Zuführvorrichtung Z. Diese führt der Nähmaschi­ne N die vom Etikettenspender 1 bereitgestellten Eti­ketten in einer für das Einnähen in das jeweilige Nähgut geeigneten Lage zu. Im Gehäuse 3 des Etikettenspenders 1 ist ein elektrischer Schrittmotor 4 vorgesehen, der zum Vorschieben eines von einer außerhalb des Gehäuses 3 an­geordneten Vorratstrommel 5 zulaufenden Etikettenbandes 6 über einen Treibriemen 7 Transportrollen 8, 9 antreibt.In FIG. 1, a label dispenser 1 according to the invention is arranged directly on the back of a sewing machine N by means of a frame 2 having several degrees of freedom. Is located at the front of the sewing machine, a known N, s feeder actuatable by a pivot drive of the sewing machine A Z. This N performs the labels supplied by the label dispenser 1 in a position suitable for sewing into the respective sewing material able to. In the housing 3 of the label dispenser 1, an electric stepping motor 4 is provided, which drives a transport belt 8, 9 via a drive belt 7 for feeding a label tape 6 running from a storage drum 5 arranged outside the housing 3.

Die zum korrekten Etikettenvorschub erforderlichen Ein­stelldaten, nämlich die Länge der verwendeten Etiketten und der Abstand der darauf vorgesehenen Lesemarken von der Vorderkante der Etiketten werden einer programmier­baren, elektronischen Steuerung vorgegeben. Diese kann entweder ebenfalls im Gehäuse 3 oder außerhalb des Eti­kettenspenders 1 untergebracht sein, wie mit Bezugs­zeichen 17 angedeutet.The setting data required for correct label feed, namely the length of the labels used and the distance of the reading marks provided thereon from the front edge of the labels, are predefined by a programmable, electronic control. This can either be accommodated in the housing 3 or outside the label dispenser 1, as indicated by reference number 17.

Zur Erfassung der Lesemarken dient ein ortsfest im Ge­häuse 3 gelagerter Lichtsensor 10 an sich bekannter Art. Im Bereich der rechtsseitigen, unteren Ecke des Gehäuses 3 ist ferner eine Falzeinrichtung 11 in Figur 1 angedeu­tet (vgl. auch Fig. 2), in der die Etiketten, die gemäß den programmierten Einstelldaten durch die Transport­rollen 8, 9 zudosiert werden, unter Umständen nach voll­zogenem Falzen, durch ein Messer 12 vom Etikettenband 6 abgeschnitten und sodann an den bereitstehenden Greifern Gz der Zuführvorrichtung Z übertragen werden. Der Lese­strahl des Lichtsensors 10 ist in einem festen Abstand a von der Schneide des Messers 12 fixiert.A light sensor 10, which is fixed in position in the housing 3 and is known per se, is used to detect the reading marks. In the area of the lower right corner of the housing 3, a folding device 11 is also indicated in FIG. 1 (see also FIG. 2) in which the labels , which are metered in according to the programmed setting data by the transport rollers 8, 9, possibly after the folding has been completed, cut off from the label tape 6 by a knife 12 and then transferred to the ready grippers G z of the feed device Z. The reading beam of the light sensor 10 is fixed at a fixed distance a from the cutting edge of the knife 12.

Dank der erfindungsgemäßen Anordnung können die zeitauf­wendige Einstellerei von Anschlägen zur Vorgabe geänder­ter Etikettenlänge und eine exakte Ausrichtung des Lichtsensors 10 auf eine neue Lesemarke jeweils vor Ver­wendung andersartiger Etiketten entfallen. Obwohl die Lesemarke durch den Lichtsensor 10 bereits während des Etikettentransportes abgetastet wird, läßt die Steuerung zunächst den programmierten Vorschub zurücklegen und veranlaßt sodann selbsttätig die Durchführung der not­wendigen weiteren Funktionsschritte.Thanks to the arrangement according to the invention, the time-consuming setting of stops for specifying changed label lengths and an exact alignment of the light sensor 10 with a new reading mark can be dispensed with each time before using different types of labels. Although the reading mark is already scanned by the light sensor 10 while the label is being transported, the controller first has the programmed feed back and then automatically carries out the necessary further functional steps.

Eine nochmalige, vergrößerte Darstellung der Falzeinrich­tung 11 ist aus der Fig. 2 ersichtlich. Unter dem Messer 12 befindet sich im Innern der Falzeinrichtung 11 eine pneumatische Blaseinheit 14. Messer 12 und Blaseinheit 14 sind von einer Klemmvorrichtung 15 umschlossen. Die Klemmvorrichtung 15 weist eine anhand eines zweifach abgewinkelten Armes 15.1 fest mit dem Gehäuse 3 verbun­dene, obere Klemmbacke 15.2 und eine bewegliche, untere Klemmbacke 15.3 auf, die mittels eines einfach abgewin­kelten Armes 15.4 exzentrisch drehbar einem Drehantrieb 16 angelenkt ist. Zur Führung der Kreiselbewegung der unteren Klemmbacke 15.3 beim Betrieb ist ferner der ange­lenkte Schenkel des einfach abgewinkelten Armes 15.4 mit einer Bohrung 15.5 ausgebildet, in der der eine Endab­schnitt einer Führungsstange 15.6 verfahrbar aufgenommen ist. Der mit einem größeren Durchmesser ausgestaltete andere Endabschnitt der Führungsstange 15.6 ist am Gehäuse 3 schwenkbar gelagert. Die pneumatische Blasein­heit 14 weist die Form eines ebenfalls abgewinkelten Flachkanals und an ihrem sich etwa bis zur Höhe des zu­laufenden Etikettenbandes erstreckenden Ende eine Mehr­zahl in die Vorschubrichtung des Etikettenbandes 6 ausge­richteter Düsenöffnungen 14.1 auf (vgl. auch Fig. 3). Das Messer 12 ist in für sich bekannter Weise an einer Welle befestigt, die parallel zur Zeichnungsebene verlaufend angeordnet und daher in der Fig. 2 nicht sichtbar ist. Die Schwenkbewegung des Messers 12 wird dann mit Hilfe eines einfachen Druckzylinders über einen Hebel betätigt, die in der Fig. 2 ebenfalls nicht sichtbar sind.A further, enlarged illustration of the folding device 11 can be seen from FIG. 2. A pneumatic blowing unit 14 is located under the knife 12 inside the folding device 11. Knife 12 and blowing unit 14 are enclosed by a clamping device 15. The clamping device 15 has an upper clamping jaw 15.2, which is fixedly connected to the housing 3 by means of a double-angled arm 15.1, and a movable, lower clamping jaw 15.3, which is articulated rotatably by means of a single-angled arm 15.4 to a rotary drive 16. For guiding the gyroscopic movement of the lower jaw 15.3 during operation, the articulated leg of the simply angled arm 15.4 is also formed with a bore 15.5 in which one end section of a guide rod 15.6 is movably received. The other end section of the guide rod 15.6, which is designed with a larger diameter, is pivotably mounted on the housing 3. The pneumatic blowing unit 14 has the shape of an angled flat channel and at its end, which extends approximately up to the height of the incoming label tape, has a plurality of nozzle openings 14.1 aligned in the direction of advance of the label tape 6 (cf. also FIG. 3). Knife 12 is fastened in a manner known per se to a shaft which runs parallel to the plane of the drawing and is therefore not visible in FIG. 2. The pivoting movement of the knife 12 is then actuated with the aid of a simple pressure cylinder via a lever, which are likewise not visible in FIG. 2.

Gegenüber der Klemmvorrichtung 15 sind in der Fig. 2 die Umrisse der Zangenbacken des Greifers G der Zuführvor­richtung Z mittels gestrichelter Linien augedeutet.Compared to the clamping device 15, the outlines of the jaws of the gripper G of the feed device Z are indicated by means of dashed lines in FIG. 2.

Die Wirkungsweise der Falzeinrichtung 11 wird anhand der Fig. 4 erläutert, die außer der in Frage stehenden Ein­richtung lediglich die beiden Transportrollen 8, 9, das zwischen diesen zulaufende Etikettenband 6 und die Wirkungslinie des Messers 12 darstellt. Vor Betriebs­beginn liegt die Vorderkante eines Etiketts auf der Höhe der Messerschneide, und die Klemmvorrichtung 15 ist bei ausgefahrener Lage der Führungsstange 15.6 geschlossen. Die ersten drei Bilder a bis c zeigen den nach der In­betriebnahme der Falzeinrichtung 11 anlaufenden Trans­port des Etikettenbandes 6. Zunächst erfolgt ein Vorschub des Etikettenbandes 6 um einen bestimmten Teilabschnitt der vorprogrammierten Gesamtstrecke als ein erster Arbeitsschritt, gegen dessen Ende sich die Klemmvorrich­tung 15 infolge der nach unten einsetzenden Kreiselbewe­gung der beweglichen, unteren Klemmbacke 15.3 zu öffnen beginnt (vgl. Bild a). Im Verlaufe eines nachfolgenden zweiten Arbeitsschrittes wird das Etikettenband 6 um einen weiteren Teilabschnitt der erforderlichen Gesamt­strecke vorgeschoben, und gleichzeitig weitet sich auch die Öffnung zwischen den Klemmbacken 15.2, 15.3 der Klemmvorrichtung 15 weiter auf (vgl. Bild b). Die Führungsstange 15.6 der beweglichen Klemmbacke 15.3 bleibt während der beschriebenen beiden Arbeitsschritte gemäß den Bildern a und b im wesentlichen in ihrer aus­gefahrenen Position. Dies ändert sich mit dem dritten Arbeitsschritt nach dem Bild c dahingehend, daß sich die bewegliche, untere Klemmbacke 15.3 unter Einfahren der Führungsstange 15.6 in ihre Bohrung 15.5 an die zuge­wandte Seitenfläche der pneumatischen Blaseinheit 14 anlegt und dadurch der daran überhängende Vorderabschnitt eines Etiketts zwischen diesen beiden Teilen eingeklemmt wird.The mode of operation of the folding device 11 is explained with reference to FIG. 4, which, apart from the device in question, only represents the two transport rollers 8, 9, the label tape 6 running between them and the line of action of the knife 12. Before the start of operation, the front edge of a label lies at the level of the knife edge, and the clamping device 15 is closed when the guide rod 15.6 is in the extended position. The first three pictures a to c show the transport of the label tape 6 starting after the commissioning of the folding device 11. First, the label tape 6 is advanced by a certain section of the preprogrammed total distance as a first work step, towards the end of which the clamping device 15 acts as a result of the following gyroscopic movement of the movable, lower jaw 15.3 begins to open at the bottom (see Fig. a). In the course of a subsequent second working step, the label tape 6 is advanced by a further partial section of the required total distance, and at the same time the opening between the clamping jaws 15.2, 15.3 of the clamping device 15 widens further (see Figure b). The guide rod 15.6 of the movable clamping jaw 15.3 remains essentially in its extended position during the two working steps described according to the pictures a and b. This changes with the third work step according to the picture c in that the movable, lower clamping jaw 15.3, when the guide rod 15.6 is retracted into its bore 15.5, rests against the facing side surface of the pneumatic blower unit 14 and thereby the front portion of a label that overhangs between these two Parts is jammed.

Wenn das Falzen des eingeklemmten Etiketts erforderlich ist, wird in einem vierten Arbeitsschritt bei unverändert eingefahrenem Zustand der Führungsstange 15.6 aus jeder der Düsenöffnungen 14.1 je ein Luftstrahl gegen das diese Öffnungen 14.1 umspannende Etikett gerichtet und gleich­zeitig das Etikettenband 6 vorgeschoben (vgl. Bild d). Durch dieses Vorgehen kann ein Etikett unabhängig von seiner Länge immer genau in der Mitte gefaltet werden.If it is necessary to fold the pinched label, in a fourth step with the guide rod 15.6 in the unchanged state, an air jet is directed out of each of the nozzle openings 14.1 against the label spanning these openings 14.1 and at the same time the label tape 6 is advanced (see Figure d). This procedure means that a label can always be folded exactly in the middle, regardless of its length.

Im nachfolgenden fünften Arbeitsschritt wird die Klemm­vorrichtung 15 geschlossen, indem sich die untere, beweg­liche Klemmbacke 15.3 unter gleichzeitigem Wiedereinfah­ren der Führungsstange 15.6 in ihre Bohrung 15.5 an die feststehende, obere Klemmbacke 15.2 anlegt. Dadurch wird das gefalzte Etikett zwecks Abtrennung vom Etiketten­band 6 mittels des Messers 12 festgehalten. Zugleich dringt der aus der Klemmvorrichtung 15 ragende Vorder­teil des gefalzten Etiketts in den bereitstehenden Grei­fer Gz der Zuführvorrichtung Z hinein (vgl. Bild e).In the following fifth step, the clamping device 15 is closed by the lower, movable clamping jaw 15.3 engaging the fixed, upper clamping jaw 15.2 while simultaneously retracting the guide rod 15.6 into its bore 15.5. As a result, the folded label is held by the knife 12 for the purpose of being separated from the label tape 6. At the same time, the front part of the folded label protruding from the clamping device 15 penetrates into the ready gripper G z of the feed device Z (cf. picture e).

In einem sechsten Arbeitsschritt schließt der Greifer G und nimmt das gefalzte Etikett aus der sich zu öffnen beginnenden Klemmvorrichtung 15. Es kann ein neuer Arbeitszyklus anlaufen (vgl. Bild f).In a sixth working step, the gripper G closes and takes the folded label out of the clamping device 15 that begins to open. A new working cycle can start (see Fig. F).

Der Etikettenspender gemäß der Erfindung gestattet eine Bereitstellung von Etiketten für das Einnähen in das Nähgut in allen drei möglichen Nähpositionen, nämlich mit dem Nähgut zu- oder abgewandter Beschriftung oder in gefaltetem Zustand.The label dispenser according to the invention allows labels to be provided for sewing into the sewing material in all three possible sewing positions, namely with the labeling facing or facing away from the sewing material or in the folded state.

Falls kein Falzen erforderlich ist, wird das über die Blaseinheit 14 vorgeschobene Etikett nach dem Einklemmen gemäß Bild c durch das Messer 12 vom Etikettenband 6 abgetrennt und anschließend durch Anblasen aus den Düsenöffnungen 14.1 unter Umkehrung seiner beiden Seiten an den Greifer Gz weiterbefördert.If no folding is required, the label advanced via the blowing unit 14 is separated from the label belt 6 by the knife 12 after being clamped in according to Figure c and then conveyed on to the gripper G z by blowing from the nozzle openings 14.1, reversing its two sides.
