Description

Die Erfindung betrifft eine Mitnehmerkupplung zwischen einem Antriebsmechanismus einer Kassettenaufnahmevorrichtung und einem Farbbandantrieb einer Farbbandkassette der im Oberbegriff des Patentanspruchs 1 angegebenen Art (DE-U-8 223 076).The invention relates to a driver clutch between a drive mechanism of a cassette holder and a ribbon drive of an ink ribbon cassette of the type specified in the preamble of claim 1 (DE-U-8 223 076).

In modernen Büromaschinen werden Farbbandkassetten verwendet, die das zum Beschreiben eines Aufzeichnungsträgers benötigte Farbband enthalten. Die Farbbandkassetten sind in Aufnahmevorrichtungen von Schreibmaschinen einsetzbar, wobei ein in dieser Vorrichtung angeordneter Antriebsmechanismus über eine Mitnehmerkupplung mit dem Farbbandantrieb in der Farbbandkassette kuppelbar ist. Um ein Aufsetzen der Farbbandkassetten in jeder Stellung der zu kuppelnden Teile zu ermöglichen, ist durch das deutsche Gebrauchsmuster 8 223 076 eine als Antriebsstift dienende Formfeder bekannt, die nur im ausgefederten Zustand mit Mitnehmerteilen des Farbbandantriebes in Eingriff steht. Eine Drehmitnahme des Farbbandantriebes erfolgt hierbei aber erst, wenn die Formfeder in eine entsprechende Ausnehmung des Mitnehmerteils einrastet. Da hierdurch ein sofortiger Antrieb des Farbbandes nicht gewährleistet ist, sind Fehler bei der Abdruckerzeugung nicht zu vermeiden.In modern office machines, ink ribbon cassettes are used which contain the ink ribbon required to write on a recording medium. The ink ribbon cassettes can be used in recording devices of typewriters, a drive mechanism arranged in this device being able to be coupled to the ink ribbon drive in the ink ribbon cassette via a driver coupling. In order to enable the ribbon cassettes to be placed in any position of the parts to be coupled, the German utility model 8 223 076 discloses a form spring which serves as a drive pin and which only engages with driver parts of the ribbon drive in the spring-out state. In this case, however, the ribbon drive is only driven in rotation when the shaped spring engages in a corresponding recess in the driver part. As this does not guarantee an immediate drive of the ribbon, errors in the generation of the imprints cannot be avoided.

Weiterhin ist durch das deutsche Gebrauchsmuster 8 113 901 eine Mitnehmerkupplung mit einem Mitnehmerzapfen bekannt, der seitlich an einem in das Kupplungsteil mittig einsteckbaren Führungszapfen angeformt ist. Diese formschlüssige Kupplung hat aber den Nachteil, daß bei einem Blockieren des Farbbandes in der Farbbandkassette Antriebselemente des Antriebsmechanismus beschädigt oder zerstört werden können.Furthermore, the German utility model 8 113 901 discloses a driver clutch with a driver pin which is formed laterally on a guide pin which can be inserted centrally into the coupling part. However, this form-fitting coupling has the disadvantage that if the ink ribbon is blocked in the ink ribbon cassette, drive elements of the drive mechanism can be damaged or destroyed.

Darüberhinaus zeigt die US-A-2 928 619 eine einen Hohlzapfen aufweisende Vorratsspule, wobei in die Öffnung des Hohlzapfens ein Führungszapfen mit Mitnehmerleisten zur Drehmitnahme einschiebbar ist. Allerdings kann der Hohlzapfen nicht ohne Zerstörung von dem Führungszapfen wieder abgezogen werden. Dieses ist aber bei austauschbaren Farbbandkassetten erforderlich.Furthermore, US-A-2 928 619 shows a supply spool having a hollow spigot, a guide spigot with driver strips for rotational driving being insertable into the opening of the hollow spigot. However, the hollow pin cannot be removed from the guide pin without being destroyed. However, this is necessary for replaceable ribbon cartridges.

Außerdem ist durch die US-A-3 312 410 eine Papiervorratsrolle bekannt, die schneidenförmige Mitnehmerkanten in einem Hohlraum zu elastischen Kupplung mit einem zylinderförmigen Antriebselement aufweist. Diese Anordnung weist keinen Hohlzapfen mit einer Hohlwandung auf, die durch das Mitnahmeelement elastisch verformt wird.In addition, a paper supply roll is known from US-A-3 312 410, which has cutting-shaped driver edges in a cavity for elastic coupling with a cylindrical drive element. This arrangement has no hollow pin with a hollow wall which is elastically deformed by the driving element.

Der Erfindung liegt die Aufgabe zugrunde, eine Mitnehmerkupplung gemäß dem Oberbegriff des Patentanspruchs 1 zu schaffen, die ein Aufsetzen der Farbbandkassetten auf die Aufnahmevorrichtungen in jeder Stellung der zu kuppelnden Teile ermöglicht, einen sofortigen Antrieb des Farbbandes nach dem Aufsetzen der Farbbandkassetten gewährleistet und eine Zerstörung oder Beschädigung der Antriebselemente des Antriebsmechanismus bei einem eventuellen Blockieren des Farbbandes sicher verhindert. Diese Aufgabe wird durch die im Patentanspruch 1 gekennzeichnete Erfindung gelöst.The invention has for its object to provide a driver clutch according to the preamble of claim 1, which allows the ribbon cartridges to be placed on the receptacles in any position of the parts to be coupled, ensures an immediate drive of the ribbon after the ribbon cartridges have been placed on and destruction or Damage to the drive elements of the drive mechanism in the event of a possible blocking of the ink ribbon is reliably prevented. This object is achieved by the invention characterized in claim 1.

Die erfindungsgemäße Mitnehmerkupplung ermöglicht ein Aufsetzen der Farbbandkassette in jeder beliebigen Stellung der zu kuppelnden Teile, wobei eine sichere Mitnahme des Farbbandes immer gewährleistet ist. Auch wird eine Beschädigung der Antriebsteile bei einem eventuellen Blockieren des Farbbandes durch Durchdrehen des Führungszapfens in dem elastisch verformten Hohlzapfen sicher verhindert.The driver coupling according to the invention enables the ink ribbon cassette to be placed in any position of the parts to be coupled, with a secure transportation of the ink ribbon being always guaranteed. Damage to the drive parts in the event of a possible blockage of the ink ribbon is also reliably prevented by turning the guide pin in the elastically deformed hollow pin.

Weitere vorteilhafte Ausgestaltungen des Erfindungsgegenstandes sind den Unteransprüchen zu entnehmen. Die Erfindung wird an einem Ausführungsbeispiel anhand der Figuren näher erläutert.Further advantageous refinements of the subject matter of the invention can be found in the subclaims. The invention is explained in more detail using an exemplary embodiment with reference to the figures.

Es zeigt:

  • Figur 1 eine Draufsicht auf die Kassettenaufnahmevorrichtung mit der Farbbandkassette im Querschnitt,
  • Figur 2 die zu kuppelnden Teile der Mitnehmerkupplung vor dem Kuppeln,
  • Figur 3 die Mitnehmerkupplung im gekuppelten Zustand und
  • Figur 4 den Führungszapfen der Mitnehmerkupplung in Draufsicht.
It shows:
  • FIG. 1 shows a plan view of the cassette receiving device with the ink ribbon cassette in cross section,
  • FIG. 2 shows the parts of the driver coupling to be coupled before coupling;
  • Figure 3 shows the driver clutch in the coupled state and
  • Figure 4 shows the guide pin of the driver clutch in plan view.

In Figur 1 ist eine Aufnahmevorrichtung 1 einer Schreib- oder ähnlichen Büromaschine mit einer aufgesetzten Farbbandkassette 2 dargestellt. In dieser Farbbandkassette 2 ist eine Vorratsspule 3 für ein Farbband 4 drehbar gelagert, von der das z.B. aus einem Karbonband bestehende Farbband 4 über Umlenkführungen 5, 6 aus einer Austrittsöffnung 7 herausgeführt, über Führungsarme 8, 9 durch die Druckstation geleitet und über eine Eintrittsöffnung 10 wieder in die Farbbandkassette 2 geleitet wird. Außerdem ist in der Farbbandkassette 2 ein als Antriebsrad ausgebildetes Stachelrad 11 drehbar gelagert, dessen Stacheln 12 mit dem Außenwickel 13 einer Aufwickelspule 14 in Antriebsverbindung steht. Diese Aufwickelspule 14 ist auf einer um eine Achse 15 schwenkbaren Schwenkhebel 16 drehbar gelagert, der durch eine Feder 17 derart beaufschlagt wird, daß die Stacheln 12 immer mit dem Außenwickel 13 der Aufwickelspule 14 in Eingriff stehen. Weiterhin ist in der Figur 1 ein Druckhammer 18 dargestellt, der z.B. elektromagnetisch antreibbar ist und durch Beaufschlagen einer Type einer Typenscheibe 20 einen Abdruck unter Zwischenschaltung des Farbbandes 4 auf einem Aufzeichnungsträger 19 erzeugt.FIG. 1 shows a receiving device 1 of a typewriter or similar office machine with an ink ribbon cassette 2 attached. In this ribbon cassette 2, a supply reel 3 for a ribbon 4 is rotatably supported, of which e.g. Ribbon 4 consisting of a carbon ribbon is guided out of an outlet opening 7 via deflection guides 5, 6, passed through the printing station via guide arms 8, 9 and is fed back into the ribbon cassette 2 via an inlet opening 10. In addition, in the ink ribbon cassette 2 a sprocket 11 designed as a drive wheel is rotatably mounted, the spikes 12 of which are in drive connection with the outer winding 13 of a winding spool 14. This take-up spool 14 is rotatably mounted on a pivotable lever 16 which can be pivoted about an axis 15 and is acted upon by a spring 17 such that the spikes 12 are always in engagement with the outer take-up 13 of the take-up spool 14. A pressure hammer 18 is also shown in FIG. is electromagnetically drivable and generates an impression by interposing the ink ribbon 4 on a recording medium 19 by applying a type of a type disk 20.

Die Mitnehmerkupplung zwischen dem Antriebsmechanismus einer Kassettenaufnahmevorrichtung 1 und dem Stachelrad 11 in der Farbbandkassette 2 besteht gemäß Figur 2 aus einem Führungszapfen 21 und einem als zweiten Kupplungsteil dienenden Hohlzapfen 22. Dieser Hohlzapfen 22 weist eine sacklochförmige Öffnung 23 auf, in die der Führungszapfen 21 mit Mitnehmerteilen 24, 25 unter elastischer Verformung der Wandung 26 des Hohlzapfens 22 zur Drehmitnahme einschiebbar ist. Je nach dem verwendeten Material für den Hohlzapfen 22 kann es hierbei auch zu einer geringen plastischen Verformung kommen. Die Mitnehmerkupplung ist in der Figur 2 vor dem Kuppelvorgang und in der Figur 3 im eingekuppelten Zustand dargestellt. Der mittig in die Öffnung 23 des Hohlzapfens 22 einsteckbare Führungszapfen 21 ist zylindrisch ausgebildet und weist mindestens eine seitlich als Mitnehmerteil ausgebildete schneidenförmige Mitnehmerkante 24; 25 auf, die parallel zur Längsmittelachse der Mitnehmerkupplung verläuft. Hierdurch ist eine sichere Drehmitnahme des Stachelrades 11 durch den z.B. über einen Schrittmotor antreibbaren Antriebsmechanismus in der Aufnahmevorrichtung 1 gewährleistet; für eine gleichmäßige Beanspruchung der Antriebsteile sind zwei diametral an dem äußeren Umfang des Führungszapfens 21 angeordnete schneidenförmige Mitnehmerkanten 24, 25 vorteilhaft. Mit dem Aufsetzen der Farbbandkassette 2 auf die Aufnahmevorrichtung 1 wird der Hohlzapfen 22 automatisch über den Führungszapfen 21 gestülpt. Die Mitnehmerkanten 24, 25 weiten hierbei den nachgiebigen Hohlzapfen 22 auf, wodurch eine sichere Drehmitnahme immer gewährleistet wird. Das Abnehmen der Farbbandkassette 2 von der Aufnahmevorrichtung 1 ist ebenfalls einfach, wobei danach die Wandung 26 die zylindrische Form wieder einnimmt. In jeder Stellung der kuppelnden Teile ist ein Aufsetzen bzw. Abnehmen der Farbbandkassette auf einfachste Weise möglich.According to FIG. 2, the driver coupling between the drive mechanism of a cassette receiving device 1 and the sprocket 11 in the ribbon cassette 2 consists of a guide pin 21 and a hollow pin 22 serving as a second coupling part. This hollow pin 22 has a blind hole-shaped opening 23 into which the guide pin 21 with driver parts 24, 25 with elastic deformation of the wall 26 of the hollow pin 22 can be inserted for rotary driving. Depending on the material used for the hollow pin 22, there may also be a slight plastic deformation. The driver clutch is in Figure 2 before Coupling process and shown in Figure 3 in the coupled state. The guide pin 21, which can be inserted centrally into the opening 23 of the hollow pin 22, is cylindrical and has at least one blade-shaped driver edge 24 formed laterally as a driver part; 25, which runs parallel to the longitudinal central axis of the driver clutch. This ensures that the pinwheel 11 is securely driven in rotation by the drive mechanism in the receiving device 1, which can be driven, for example, via a stepping motor; For a uniform loading of the drive parts, two blade-shaped driver edges 24, 25 arranged diametrically on the outer circumference of the guide pin 21 are advantageous. When the ink ribbon cassette 2 is placed on the receiving device 1, the hollow pin 22 is automatically placed over the guide pin 21. The driver edges 24, 25 here expand the flexible hollow pin 22, whereby a safe rotary driving is always guaranteed. The removal of the ribbon cassette 2 from the receiving device 1 is also simple, after which the wall 26 assumes the cylindrical shape again. In any position of the coupling parts, the ribbon cassette can be put on or taken off in the simplest way.

Bei einem Blockieren der Vorratsspule bzw. des Stachelrades 11 kann der Führungszapfen 21 in der Öffnung 23 des Hohlzapfens 22 durchdrehen. Hierdruch wird eine Beschädigung oder Zerstörung der Antriebsteile sicher verhindert.If the supply spool or the pinwheel 11 is blocked, the guide pin 21 can rotate in the opening 23 of the hollow pin 22. This reliably prevents damage or destruction of the drive parts.
