Abstract

The invention relates to a tape dispenser for producing lengths of tape. The tape dispenser comprises a rotatable roller on which the tape is wound up and a rotatable take-off roller across which the tape to be taken off is guided. The take-off roller has at least one perforation element that is directed against the surface of support of the tape and that is used to perforate the tape. The dispenser is further provided with latch elements that block the take-off roller if the tape has covered a certain distance once it has been perforated. The latch elements release the take-off roller once the perforated section at the tape's end is separated from the tape.

Description

Bandspender Tape dispenser
Die Erfindung betrifft einen Bandspender nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a tape dispenser according to the preamble of patent claim 1.
In vielen Anwendungsbereichen des täglichen Lebens werden oft Bandstücke bestimmter Länge - beispielsweise Stücke von Klebeband für Pakete oder dergleichen - benötigt. Zum Erzeugen von solchen Bandstücken sind einfache Vorrichtungen - sogenannte Band-Abroller - bekannt, mit denen das Band von einer Rolle abgewickelt und über ein Schneideelement geführt wird. Wenn das freie Ende des Bandes die gewünschte Länge erreicht hat, wird es mit dem Schneideelement abgeschnitten. Bei diesen Vorrichtungen wird die Länge des abzuschneidenden Bandes durch den Benutzer bestimmt, indem er das Band in gewünschter Länge abwickelt und dann abschneidet. Zum Abschneiden muss er das Bandende so über das Schneideelement führen, dass dieses schneidend auf das Band einwirken kann. Für die Erzeugung von Bandstücken mit vorgegebener Länge sind die bekannten Vorrichtungen nicht geeignet. Zudem ist ihre Handhabung insbesondere zum sicheren Abschneiden umständlich und bei längerer Benutzung deshalb ermüdend.In many areas of daily life, pieces of tape of a certain length - for example pieces of adhesive tape for packages or the like - are often required. Simple devices - so-called tape unwinders - are known for producing such tape pieces, with which the tape is unwound from a roll and guided over a cutting element. When the free end of the tape has reached the desired length, it is cut off with the cutting element. In these devices, the length of the tape to be cut is determined by the user by unwinding the tape to the desired length and then cutting. To cut it, it must guide the end of the tape over the cutting element so that it can act on the tape in a cutting manner. The known devices are not suitable for the production of pieces of tape with a predetermined length. In addition, their handling is cumbersome, especially for safe cutting, and is therefore tiring when used for a long time.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen einfachen Bandspender der eingangs genannten Art zu schaffen, der sehr handlich ist und der zum Abschneiden des Bandes keine besonderen Manipulationen durch den Benutzer erfordert.The present invention has for its object to provide a simple tape dispenser of the type mentioned, which is very handy and does not require any special manipulations by the user to cut the tape.

In den Figuren sind für dieselben Elemente jeweils dieselben Bezugszeichen verwendet worden und erstmalige Erklärungen betreffen alle Figuren, wenn nicht ausdrücklich anders erwähnt.In the figures, the same reference numerals have been used for the same elements, and first-time explanations apply to all figures, unless expressly stated otherwise.
Die Figuren 1 und 2 zeigen die wesentlichen Teile des Bandspenders, wobei Figur 1 eine seitliche Ansicht in das Innere des geöffneten Bandspenders zeigt. Er besteht in seinen Hauptteilen aus einem Grundgehäuse 4 und einem auf das Grundgehäuse 4 aufsteckbaren Gehäuseaufsatz 12. Die Verbindung zwischen Grundgehäuse 4 und Gehäuseaufsatz 12 erfolgt über Rastelemente 18. Das Grundgehäuse 4 besteht aus zwei voneinander trennbaren Gehäusehälften 4a, 4b, die durch Zusammenstecken zusammengefügt werden (vgl. Figur 2). In Figur 1 ist ferner eine Gehäusehälfte weggelassen, um den Blick in das Innere des Bandspenders zu ermöglichen. Am Gehäuseaufsatz 12 ist ein Träger 3 vorgesehen, an dem eine Rolle 1 mit dem aufgewickelten Band 2 drehbar angebracht ist. Am Grundgehäuse 4 ist eine drehbare Abwickelrolle 5 angebracht, über die das von der Rolle 1 kommende Band 2 geführt ist. Das freie Ende des Bandes 2 tritt aus einer Öffnung 8 aus dem Grundgehäuse 4 aus. Die Abwickelrolle 5 weist ein Perforationselement 6 auf, das gegen die Unterseite, d.h. gegen die auf der Abwickelrolle 5 aufliegende Fläche des Bandes 2 gerichtet ist. Als Perforationselement 6 ist mindestens ein beispielsweise dreieckförmiges Messer vorhanden, dessen eine Spitze aus der Abwickelrolle 5 herausragt. Es können auch mehrere solcher Messerelemente nebeneinander vorgesehen werden. Ferner ist im Grundgehäuse 4 ein Arretierungselement 7 - z.B. ein an einem Ende eingespannter Federstab - untergebracht, der in noch näher beschriebener Weise in die Abwickelrolle 5 greift und diese in einer bestimmten Stellung blockiert und dann wieder freigibt. Ferner sind im Innern des Bandspenders nach Bedarf noch an sich bekannte Bandführungen vorgesehen, um das Band bis zu seinem Austritt zu führen. Zum Ersetzen einer aufgebrauchten Rolle 1 durch eine neue genügt es, den Gehäuseaufsatz 12 vom Grundgehäuse 4 zu trennen und mit einer neuen Rolle zu bestücken. Denkbar ist auch, den ganzen Gehäuseaufsatz 12 samt Rolle 1 zu ersetzen (siehe Figur 2).Figures 1 and 2 show the essential parts of the tape dispenser, wherein Figure 1 shows a side view of the inside of the opened tape dispenser. Its main parts consist of a basic housing 4 and a housing attachment 12 which can be plugged onto the basic housing 4. The connection between the basic housing 4 and the housing attachment 12 takes place via latching elements 18. The basic housing 4 consists of two separable housing halves 4a, 4b which are joined together by plugging them together (see Figure 2). In Figure 1, a housing half is also omitted to allow a view into the interior of the tape dispenser. A carrier 3 is provided on the housing attachment 12, on which a roller 1 with the wound tape 2 is rotatably attached. A rotatable unwinding roll 5 is attached to the basic housing 4, via which the band 2 coming from the roll 1 is guided. The free end of tape 2 occurs from an opening 8 from the basic housing 4. The unwinding roll 5 has a perforation element 6 which is directed against the underside, ie against the surface of the band 2 resting on the unwinding roll 5. At least one triangular knife, for example, is present as the perforation element 6, the tip of which protrudes from the unwinding roller 5. Several such knife elements can also be provided side by side. Furthermore, a locking element 7 - for example a spring bar clamped at one end - is accommodated in the basic housing 4, which engages in the unwinding roller 5 in a manner described in more detail and blocks it in a specific position and then releases it again. Furthermore, known tape guides are provided inside the tape dispenser as required to guide the tape until it exits. To replace a used roll 1 with a new one, it is sufficient to separate the housing attachment 12 from the basic housing 4 and to equip it with a new roll. It is also conceivable to replace the entire housing attachment 12 including roller 1 (see FIG. 2).
Anhand der Figuren 3 bis 6 wird die Funktionsweise des erfindungsgemässen Bandspenders näher erläutert, wobei nur die zum Verständnis notwendigen Teile dargestellt sind. Figur 3 zeigt die Ausgangslage, wo das freie Ende des Bandes 2 über die Abwickelrolle 5 hinausragt, nachdem vorher ein Bandstück abgetrennt worden ist. Soll ein weiteres Bandstück erzeugt werden, zieht der Benutzer das Band 2 am freien Ende weiter heraus. Dabei dreht sich die Abwickelrolle 5 in Pfeilrichtung und das Perforationselement 6 läuft in gleicher Richtung mit. Das freie Ende des Federstabes 7 greift in eine in der Abwickelrolle 5 verlaufende Nut 9 und wird beiDrehung der Abwickelrolle 5 darin geführt. Die Nut 9 verläuft spiralförmig auf der Oberfläche der Abwickelrolle 5 von aussen nach innen. Dadurch wird beim Abwickeln des Bandes 2 der Federstab 7 vorgespannt.The mode of operation of the tape dispenser according to the invention is explained in more detail with reference to FIGS. 3 to 6, only the parts necessary for understanding being shown. Figure 3 shows the starting position where the free end of the tape 2 protrudes beyond the unwinding roller 5 after a piece of tape has been separated. If another piece of tape is to be produced, the user pulls tape 2 out further at the free end. The unwinding roll 5 rotates in the direction of the arrow and the perforation element 6 runs in the same direction. The free end of the spring bar 7 engages in a groove 9 running in the unwinding roller 5 and is guided therein when the unwinding roller 5 is rotated. The groove 9 runs spirally on the surface of the unwinding roller 5 from the outside inwards. Characterized the spring rod 7 is biased when unwinding the tape 2.
Im Laufe der Drehbewegung der Abwickelrolle 5 gelangt das Perforationselement 6 in eine Lage, wo es das Band 2 zunächst berührt und dann durchsticht (sieheIn the course of the rotational movement of the unwinding roll 5, the perforation element 6 comes into a position where it first touches the tape 2 and then pierces (see
Figur 4). Wird das Band 2 weiter fortbewegt, dreht sich die Abwickelrolle 5 weiter, bis sie durch den in der Nut 9 auf einen Anschlag 10 auflaufenden Federstab 7 blockiert wird (Figur 5). Wird weiter in Pfeilrichtung am Band 5 gezogen, wird das freie Ende des Bandes 2 an der vorher durch das Perforationselement 6 teilweise durchstossenen Stelle vom Band 2 abgetrennt. Dabei wird das Drehmoment, wel- ches durch die auf das Band 2 ausgeübte Zugkraft auf die Abwickelrolle 5 wirkt, plötzlich aufgehoben. Demzufolge gelangt der Federstab 7 infolge seiner Vorspannung unverzüglich aus der die Drehung der Abwickelrolle 5 blockierenden Stellung in eine die Drehbewegung freigebende Stellung innerhalb der Nut 9. In diesem Bereich ist die Nut 9 vorzugsweise z-förmig ausgebildet. Der Federstab 7 nimmt wieder seine Ruhelage mit einer geringeren Vorspannung ein. Damit ist die Ausgangslage gemäss Figur 1 wieder erreicht und es kann in beschriebener Weise ein nächstes Bandstück erzeugt werden, indem der Benutzer das Band 2 wiederum an seinem freien Ende aus dem Gehäuse 4 herauszieht. Die Länge der erzeugten Bandstücke wird durch den äusseren Umfang der Abwickelrolle 5 be- stimm*Figure 4). If the belt 2 is moved further, the unwinding roll 5 continues to rotate, until it is blocked by the spring bar 7 running into the groove 9 onto a stop 10 (FIG. 5). If the band 5 is pulled further in the direction of the arrow, the free end of the band 2 is severed from the band 2 at the point previously pierced by the perforation element 6. The torque which acts on the unwinding roller 5 due to the tensile force exerted on the band 2 is suddenly canceled. As a result, due to its pretensioning, the spring bar 7 immediately moves from the position blocking the rotation of the unwinding roller 5 to a position within the groove 9 which releases the rotary movement. In this area, the groove 9 is preferably of Z-shape. The spring bar 7 resumes its rest position with a lower preload. The starting position according to FIG. 1 is thus reached again and a next piece of tape can be produced in the manner described by the user again pulling the tape 2 out of the housing 4 at its free end. The length of the tape pieces produced is determined by the outer circumference of the unwinding roll 5 *
In Figur 7 ist eine Variante der Abwickelrolle 5' gezeigt, wobei die Nut 9' in etwa mittig auf der Aufwickelrolle 5' und seitlich dazu zwei nebeneinander liegenden Perforationselemente 6' vorgesehen sind. Insbesondere ist daraus die z-förmige Ausbildung der Nut 9' im Bereich des Anschlags 10' mit grösseren Rundungen vorgesehen. Die hier gezeigte Nut 9' weist aber genau dieselbe Funktionsweise auf, wie bei der mit Bezug auf die Figuren 3 bis 6 beschriebenen Abwickelrolle 5', d.h. die Reibflächen im z-förmigen Bereich der Nut 9' verhindern, dass der Federstab 7 in die Ausgangsposition zurückspringen kann, so lange das Klebband 2 noch nicht abgerissen ist. Die weiteren Aussparungen 20' auf der Aufwickelrolle 5' dienen dazu, dass das Klebband 2 nicht zu stark an deren Oberfläche haften bleibt.A variant of the unwinding roll 5 'is shown in FIG. 7, the groove 9' being provided approximately centrally on the winding roll 5 'and laterally two perforation elements 6' lying next to one another. In particular, the z-shaped design of the groove 9 'in the area of the stop 10' with larger curves is provided therefrom. However, the groove 9 'shown here has exactly the same function as that of the unwinding roll 5' described with reference to FIGS. 3 to 6, i.e. the friction surfaces in the z-shaped area of the groove 9 'prevent the spring bar 7 from springing back into the starting position as long as the adhesive tape 2 has not yet been torn off. The further cutouts 20 'on the winding roll 5' serve to ensure that the adhesive tape 2 does not adhere too strongly to the surface thereof.
In Figur 8 ist ein Bandspender mit einer alternativen Ausführungsform des Arretie- rungselementes dargestellt. Figur 8a zeigt eine Ansicht in das Innere einer Gehäusehälfte 4a mit einem Träger 3 zur Aufnahme der Bandrolle. Die Abwickelrolle 5 weist seitlich eine Trägerscheibe 14 auf, an der eine Spannfeder 13 als Arretierungselement angebracht ist (siehe Figur 8b). Die Spannfeder 13 besteht aus einem fest mit der Trägerscheibe 14 verbundenen Teil 13a und einem Federarm 13b mit einem Federkopf 16. Im Innern des Gehäuses 4 ist eine spiralförmig ver- laufende Nut 15 mit einem Anschlag 17 angeordnet. Die Scheibe 14 ist so eingesetzt, dass der Federkopf 16 in die Nut 15 greift. In der Ausgangslage zum Erzeugen eines Bandstückes befindet sich der Federkopf 16 an der mit „x" bezeichneten Stelle in der Nut 15. Dreht sich die Abwickelrolle 5 in Pfeilrichtung, gelangt der Federkopf 16 aus der Ausgangslage bis zum Anschlag 17, und es wird eine konti- nuierlich zunehmende Druckkraft auf den Federarm 13b ausgeübt. Der Federarm 13b wird dabei vorgespannt. Das hier gezeigte Arretierungselement ist einstückig aus einem geeigneten Zweikomponenten-Kunststoff im Spritzgussverfahren her-, gestellt.FIG. 8 shows a tape dispenser with an alternative embodiment of the locking element. Figure 8a shows a view into the interior of a housing half 4a with a carrier 3 for receiving the tape roll. The unwinding roll 5 has a support disk 14 on the side, on which a tension spring 13 is attached as a locking element (see FIG. 8b). The tension spring 13 consists of a part 13a fixedly connected to the carrier disk 14 and a spring arm 13b with a spring head 16. In the interior of the housing 4 there is a spiral groove 15 with a stop 17. The disc 14 is inserted so that the spring head 16 engages in the groove 15. In the starting position for producing a piece of tape, the spring head 16 is located at the point labeled “x” in the groove 15 - Nuclearly increasing compressive force is exerted on the spring arm 13b, the spring arm 13b being preloaded The locking element shown here is made in one piece from a suitable two-component plastic by injection molding.
Im Übrigen ist die prinzipielle Funktionsweise zum Erzeugen eines Bandstückes die gleiche wie beim Bandspender gemäss den Figuren 1 bis 6. Auf dem Weg des Federkopfes 16 zum Anschlag 17 wird das über die Abwickelrolle 5 laufende Band vom Perforationselement 6 durchstossen. Hierauf läuft der Federkopf 16 auf den Anschlag 17 auf und die Abwickelrolle 5 wird blockiert. Beim Abreissen des perfo- rierten Bandstückes springt der Federkopf 16 unverzüglich in die Ausgangslage „x". Die Vorspannung des Federarms 13b ist aufgehoben und der Bandspender steht zum Erzeugen eines weiteren Bandstückes bereit. Otherwise, the basic mode of operation for producing a piece of tape is the same as for the tape dispenser according to FIGS. 1 to 6. On the way of the spring head 16 to the stop 17, the tape running over the unwinding roller 5 is pierced by the perforation element 6. The spring head 16 then runs onto the stop 17 and the unwinding roller 5 is blocked. When the perforated piece of tape is torn off, the spring head 16 jumps immediately into the starting position “x”. The pretension of the spring arm 13b is released and the tape dispenser is ready to produce another piece of tape.
