Description

JOURNALDRUCKER MIT SCHWENKBARER AUFWICKELANORDNUNG JOURNAL PRINTER WITH SWIVELING REELING ARRANGEMENT
Druckerprinter
Die Erfindung betrifft einen Drucker, umfassend ein Druk- kerchassis und ein dieses einschließendes Druckergehäuse zur Aufnahme mindestens einer Druckstation mit einem Druck- köpf, einem dem Druckkopf zugeordneten Druckwiderlager und einem Lager für eine Vorratsrolle eines bahnförmigen Druckträgers, der zwischen Druckkopf und Druckwiderlager hindurchgeführt wird, wobei das Druckwiderlager um eine zur Lagerachse der Vorratsrolle parallele Schwenkachse zwischen einer Druckstellung, in der es mit dem Druckkopf einen Druckspalt für den Druckträger bildet, und einer dem Druckkopf fernen Servisestellung verschwenkbar ist, in der eine Vorratsrolle in den Drucker einlegbar ist.The invention relates to a printer comprising a printer chassis and a printer housing enclosing it for receiving at least one printing station with a print head, a print abutment assigned to the print head and a bearing for a supply roll of a web-shaped print carrier which is passed between the print head and the print abutment. the print abutment being pivotable about a pivot axis parallel to the bearing axis of the supply roll between a print position in which it forms a print gap for the print carrier with the print head, and a service position remote from the print head in which a supply roll can be inserted into the printer.
Ein Drucker der vorstehend genannten Art ist beispielsweise als Bondrucker für Kassenstationen bekannt. Das verschwenkbare Druckwiderlager ermöglicht ein rasches Einlegen einer neuen Vorratsrolle, ohne daß der Druckträger, das heißt üblicherweise eine Papierbahn in den Druckspalt eingefädelt werden muß, was früher oft zu störenden Unterbrechungen des Kassenbetriebes führte.A printer of the type mentioned above is known, for example, as a receipt printer for cash register stations. The pivotable pressure abutment enables a new supply roll to be inserted quickly without the printing medium, that is to say usually a paper web, having to be threaded into the printing nip, which in the past often led to disruptive interruptions in the checkout process.
Daneben sind Journaldrucker bekannt, bei denen der Druckträger nicht abgerissen sondern nach dem Bedrucken auf ei- ner Aufwickelwelle aufgewickelt wird. Bei diesen Druckern wird die Vorratsrolle in der Regel axial auf eine Welle aufgeschoben. Die Druckträgerbahn muß dann durch den Druckspalt gefädelt und mit der Aufwickelwelle verbunden werden. Dies ist häufig zeitraubend und verursacht bei großem Andrang bei den Kassenplätzen unerwünschte Betriebsstörungen.In addition, journal printers are known in which the print carrier is not torn off but is wound up on a take-up shaft after printing. With these printers, the supply roll is usually pushed axially onto a shaft. The print carrier web must then be threaded through the pressure gap and connected to the take-up shaft become. This is often time-consuming and causes undesirable operational disruptions when there is a large crowd at the checkout counters.
Der Erfindung liegt die Aufgabe zugrunde, einen Drucker der eingangs genannten Art anzugeben, der als Journaldrucker verwendet werden kann und bei dem die Druckträger- Vorratsrolle rasch und bequem eingelegt werden kann.The invention has for its object to provide a printer of the type mentioned, which can be used as a journal printer and in which the print carrier supply roll can be inserted quickly and easily.
Diese Aufgabe wird bei einem Drucker der eingangs genannten Art dadurch gelöst, daß in dem Drucker ein Lager für eine motorisch antreibbare Aufwickelwelle für den Druckträger vorgesehen ist, deren Drehachse mit der Schwenkachse des Druckwiderlagers zusammenfällt .This object is achieved in a printer of the type mentioned in that a bearing for a motor-driven winding shaft for the printing medium is provided in the printer, the axis of rotation of which coincides with the pivot axis of the pressure abutment.
Die erfindungsgemäß vorgeschlagene Anordnung der Aufwickel- welle erlaubt es, wie bei den bereits bekannten Bon- Druckern das Druckwiderlager zu verschwenken, ohne daß dabei die Aufwickelwelle im Weg ist. Dadurch kann der Druckspalt weit geöffnet und die Vorratsrolle für die Druckträgerbahn bequem in ihr Lager eingelegt werden. Die Druckträgerbahn wird um das Druckwiderlager herumgeführt und mit der Aufwickelwelle verbunden. Ein Einfädeln des Druckträgers in den Druckspalt ist nicht erforderlich. Der erfindungsgemäße Drucker ist nicht nur äußerst einfach und ohne die Gefahr von Betriebsstörungen zu bedienen, sondern auch einfach herzustellen.The arrangement of the take-up shaft proposed according to the invention makes it possible, as with the already known receipt printers, to pivot the print abutment without the take-up shaft being in the way. As a result, the printing gap can be opened wide and the supply roll for the print carrier web can be conveniently placed in its storage. The print carrier web is guided around the pressure abutment and connected to the take-up shaft. It is not necessary to thread the print carrier into the print nip. The printer according to the invention is not only extremely simple to operate and without the risk of malfunctions, but is also easy to manufacture.
Um trotz der Verschwenkbarkeit des Druckwiderlagers eine stabile Lagerung für dieses zu ermöglichen, ist das Druckwiderlager zweckmäßigerweise an einem an dem Druckerchassis schwenkbar gelagerten Rahmen angeordnet . Vorzugsweise ist das Druckwiderlager eine zu der Schwenkachse parallele Schreibwalze, die in ihrer Druckstellung mit einem An- triebsmotor koppelbar sein kann. Damit dient die Schreibwalze gleichzeitig als Transportwalze für den Druckträger.In order to enable stable support for the print abutment despite the pivotability of the print abutment, the print abutment is expediently arranged on a frame pivotably mounted on the printer chassis. The pressure abutment is preferably a platen roller parallel to the swivel axis, which in its printing position is attached to an drive motor can be coupled. The platen roller also serves as a transport roller for the print carrier.
Zur Vereinfachung der Anordnung ist es zweckmäßig, wenn die Aufwickelwelle von demselben Motor wie die Schreibwalze an- getrieben werden kann. Da jedoch der Durchmesser des Wik- kels auf der Aufwickelwelle ständig zunimmt, nimmt die Umfangsgeschwindigkeit am Wickel der Aufwickelwelle zu, während die Umfangsgeschwindigkeit an der Schreibwalze gleichbleibt. Um nun einen gleichzeitigen Antrieb von Schreibwal- ze und Aufwickelwelle durch denselben Antriebsmotor zu ermöglichen, wird vorgeschlagen, daß die Aufwickelwelle mit dem die Schreibwalze antreibenden Antriebsmotor über eine Rutschkupplung gekoppelt ist.To simplify the arrangement, it is expedient if the winding shaft can be driven by the same motor as the platen roller. However, since the diameter of the winding on the take-up shaft is constantly increasing, the peripheral speed on the take-up shaft of the take-up shaft increases, while the peripheral speed on the platen roller remains the same. In order to enable simultaneous drive of the platen roller and take-up shaft by the same drive motor, it is proposed that the take-up shaft be coupled to the drive motor driving the platen roller via a slip clutch.
Zweckmäßigerweise hat das Druckergehäuse ein Gehäuseunter- teil und einen Deckel, der an dem Gehäuseunterteil um eine zur Schwenkachse parallele Deckelachse schwenkbar gelagert und zwischen einer Schließstellung und einer Öffnungsstellung verschwenkbar ist, in der er das Auswechseln der Vorratsrolle und der Aufwickelwelle sowie das Verschwenken des Druckwiderlagers in dessen Servicestellung ermöglicht . Dabei kann die Bedienung des Druckers noch dadurch vereinfacht werden, daß der Deckel auf einem an seine Schließstellung angrenzenden Teil seines Schwenkweges lösbar mit dem Druckwiderlager so gekoppelt ist, daß dieses beim Ver- schwenken des Deckels zwischen seiner Druckstellung und seiner Servicestellung und vice versa verstellt wird. Die Bedienungsperson kann also mit einem einzigen Handgriff den Deckel öffnen und gleichzeitig das Druckwiderlager in seine Servicestellung verschwenken, so daß nicht nur die Aufwik- kelwelle herausgenommen werden kann, sondern auch das Lager für die Vorratsrolle freiliegt. In der gleichen Weise wird beim Zuklappen des Deckels auch das Druckwiderlager aus seiner Servicestellung wieder in die Druckstellung verschwenkt .The printer housing expediently has a lower housing part and a cover which is pivotably mounted on the lower housing part about a cover axis parallel to the pivot axis and can be pivoted between a closed position and an open position, in which it exchanges the supply roll and the winding shaft as well as the pivoting of the pressure abutment in whose service provision enables. The operation of the printer can be simplified further in that the cover is releasably coupled to the pressure abutment on a part of its pivoting path adjacent to its closed position in such a way that when the cover is pivoted it is adjusted between its print position and its service position and vice versa , The operator can thus open the lid with a single hand movement and at the same time pivot the pressure abutment into its service position, so that not only the winding shaft can be removed, but also the bearing for the supply roll is exposed. In the same way when the cover is closed, the pressure abutment is also pivoted out of its service position into the pressure position.
Die Kopplung zwischen Deckel und Druckwiderlager kann dabei auf einfache Weise so erfolgen, daß an einem deckelfesten Abschnitt mindestens ein Haken ausgebildet ist, der auf einem Teil des Deckelschwenkweges einen mit dem Druckwiderlager oder dem Rahmen verbundenen Abschnitt übergreift .The coupling between the cover and the pressure abutment can be carried out in a simple manner in such a way that at least one hook is formed on a cover-fixed section, which overlaps a section connected to the pressure abutment or the frame on part of the cover pivot path.
Der Druckkopf kann in an sich bekannter Weise ein Thermo- druckkopf sein. Ferner kann in dem Druckergehäuse eine weitere Druckstation mit einem Druckkopf, einem diesem zugeordneten Druckwiderlager und einem Lager für eine Vorrats- rolle eines bahnfδrmigen Druckträgers angeordnet sein, wobei beide Druckkopfe gemeinsam ansteuerbar sind. Die beiden Druckstationen können beispielsweise den Bondrucker und den Journaldrucker eines Kassendruckers bilden.The printhead can be a thermal printhead in a manner known per se. Furthermore, a further printing station can be arranged in the printer housing with a print head, a print abutment assigned to it and a bearing for a supply roll of a web-shaped print carrier, both print heads being controllable together. The two printing stations can form, for example, the receipt printer and the journal printer of a POS printer.

Der in Figur 1 dargestellte, allgemein mit 10 bezeichnete Drucker hat ein Druckergehäuse 12 mit einem Gehäuseunter- teil 14, das eine Bondruckstation 16 und eine Journaldruckstation 18 enthält und im Bereich der Bondruckstation 16 durch einen Deckel 20 und im Bereich der Journaldrucksation 18 durch einen Deckel 22 verschlossen ist. An seiner Vorderseite hat das Druckergehäuse 12 ein Bedienfeld 24.The printer shown in FIG. 1, generally designated 10, has a printer housing 12 with a lower housing part 14 which contains a receipt printing station 16 and a journal printing station 18 and in the area of the receipt printing station 16 by a cover 20 and in the area of the journal printing station 18 by a cover 22 is closed. The printer housing 12 has a control panel 24 on its front side.
Die Bondruckstation 16 hat in an sich bekannter Weise einen Druckkopf, ein Druckwiderlager und ein Lager für eine Vorratsrolle eines Druckträgers und wird hier nicht näher erläutert . Die Figur 2 zeigt den Drucker 10 mit geöffnetem Deckel 22. Man erkennt Teile der Journaldruckstation 18, nämlich eine Vorratsrolle 26 für den bahnformigen Druckträger und eine Aufwickelwelle 28, auf die der bahnfδrmige Druckträger nach dem Bedrucken aufgewickelt wird. Die Auf- wickelwelle 28 ist in offenen Lagergabeln 30 (von denen in Figur 2 nur eine zu sehen ist) des Druckerchassis gelagert. Ferner erkennt man ein Druckwiderlager 32 in Form einer Schreibwalze, das einem in Figur 2 nicht erkennbaren Ther- modruckkopf zugeordnet und an einem Schwenkrahmen 34 befestigt ist. Dieser hat zwei zueinander parallele Rahmenholme 36, die mit ihren der Schreibwalze 32 fernen freien Enden an dem Druckerchassis um eine zur Achse der Aufwickelwelle 28 co-axiale Schwenkachse 38 in nicht dargestellter Weise schwenkbar gelagert sind. Das Zusammenwirken dieser Teile der Journaldruckstation 18 wird nun anhand der schemati- sehen Figuren 3 bis 6 näher erläutert .The receipt printing station 16 has a print head, a print abutment and a bearing for a supply roll of a print carrier in a manner known per se and is not explained in more detail here. FIG. 2 shows the printer 10 with the cover 22 open. Parts of the journal printing station 18 can be seen, namely a supply roll 26 for the web-shaped print carrier and a take-up shaft 28, on which the web-shaped print carrier is wound after printing. The take-up shaft 28 is mounted in open bearing forks 30 (only one of which can be seen in FIG. 2) of the printer chassis. A pressure abutment 32 in the form of a platen roller can also be seen, which is assigned to a thermal print head which cannot be seen in FIG. 2 and is fastened to a swivel frame 34. This has two mutually parallel frame spars 36, which are pivotally mounted with their free ends remote from the platen roller 32 on the printer chassis about a pivot axis 38, which is coaxial with the axis of the winding shaft 28, in a manner not shown. The interaction of these parts of the journal printing station 18 will now be explained in more detail with reference to the schematic FIGS. 3 to 6.
Gemäß den Figuren 3, 5 und 6 liegt die Vorratsrolle 26 für die Druckträgerbahn 40 in einer Lagermulde 42. Die Druckträgerbahn 40 verläuft von der Vorratsrolle 26 über die Schreibwalze 32 zur Aufwickelwelle 28. Die Schreibwalze 32 und die Aufwickelwelle 28 werden gemäß Figur 4 von einem gemeinsamen Antriebsmotor 44 über Zwischenzahnräder 46, 47 angetrieben. Dabei erfolgt der Antrieb der Aufwickelwelle 28 über eine nicht dargestellte Rutschkupplung, um der Tatsache Rechnung zu tragen, daß sich die Umfangsgeschwindig- keit des Wickels auf der Aufwickelwelle 28 mit zunehmendem Wickeldurchmesser verändert .According to FIGS. 3, 5 and 6, the supply roll 26 for the print carrier web 40 lies in a storage trough 42. The print carrier web 40 runs from the supply roll 26 via the platen roller 32 to the take-up shaft 28. The platen roller 32 and the take-up shaft 28 are, according to FIG common drive motor 44 driven via intermediate gears 46, 47. The winding shaft 28 is driven via a slip clutch (not shown) in order to take into account the fact that the circumferential speed of the winding on the winding shaft 28 changes with increasing winding diameter.
Der Deckel 22 ist um eine zur Schwenkachse 38 des Rahmens 34 parallele Schwenkachse 48 an dem Gehäuseunterteil 14 schwenkbar gelagert, so daß er zwischen seiner in Figur 3 dargestellten Schließstellung und seiner in der Figur 6 dargestellten Öffnungsstellung verschwenkbar ist. Nahe dem vorderen Ende einer Seitenwand 50 des Deckels 22 ist ein Haken 52 mit einer Hakenöffnung 54 ausgebildet. Wird der Deckel 22 aus der in der Figur 6 dargestellten Öffnungs- Stellung im Gegenuhrzeigersinn um die Schwenkachse 48 in Richtung auf seine in der Figur 3 dargestellt Schließstel- lung verschwenkt, so trifft er mit einer in die Hakenδff- nung 54 übergehenden Rampenfläche 56 gegen einen Wellenzapfen 58 der Schreibwalze 32 (Figur 5) . Beim weiteren Verschwenken in Richtung auf seine Schließstellung nimmt der Deckel 22 nun den Schwenkrahmen 34 mit der Schreibwalze 32 mit und verschwenkt die Schreibwalze 32 in ihre in der Figur 3 dargestellte Druckstellung, in der sie an einem Ther- modruckkopf 60 anliegt. Die Schreibwalze 32 und der Thermo- druckkopf 60, der durch eine Feder 62 gegen die Schreibwal- ze 32 gespannt wird, bilden einen Druckspalt 64, durch den die Druckträgerbahn 40 hindurchgeführt wird.The cover 22 is pivotally mounted on the lower housing part 14 about a pivot axis 48 parallel to the pivot axis 38 of the frame 34, so that it can be pivoted between its closed position shown in FIG. 3 and its open position shown in FIG. A hook 52 with a hook opening 54 is formed near the front end of a side wall 50 of the cover 22. If the cover 22 is moved counterclockwise from the open position shown in FIG. 6 about the pivot axis 48 in the direction of its closed position shown in FIG. pivoted, it strikes with a ramp surface 56 merging into the hook opening 54 against a shaft journal 58 of the platen roller 32 (FIG. 5). Upon further pivoting in the direction of its closed position, the cover 22 now takes the pivot frame 34 with the platen roller 32 and pivots the platen roller 32 into the printing position shown in FIG. 3, in which it bears against a thermal print head 60. The platen roller 32 and the thermal print head 60, which is tensioned against the platen roller 32 by a spring 62, form a printing nip 64 through which the print carrier web 40 is guided.
Soll eine neue Vorratsrolle 26 eingelegt werden oder muß aus einem anderen Grunde der Drucker geöffnet werden, so wird der Deckel 22 aus der in der Figur 3 dargestellten Schließstellung im Uhrzeigersinn verschwenkt, wobei er gleichzeitig den Schwenkrahmen 34 zusammen mit der Schreibwalze 32 ebenfalls im Uhrzeigersinn in die in der Figur 5 dargestellte Servicestellung verschwenkt. In dieser Stellung kommt der Wellenzapfen 58 aus der Hakenöffnung 54 frei, so daß die Kopplung zwischen dem Schwenkrahmen 34 und dem Deckel 22 aufgehoben wird und der Deckel 22 aus der in der Figur 5 dargstellten Zwischenstellung in die in der Figur 6 dargestellte Öffnungsstellung verschwenkt werden kann. In der Servicestellung des Schwenkrahmens 34 sind Druckkopf 60 und Schreibwalze 32 weit voneinander getrennt. Die Lagermulde 42 und die Aufwickelwelle 28 sind frei zugänglich. Die Aufwickelwelle 28 mit dem darauf gebildeten Wickel kann aus den Lagergabeln 30 herausgenommen und eine neue Aufwickelwelle 28 eingelegt werden. Ferner wird eine neue Vorratsrolle 26 in die Lagermulde 42 eingelegt und die Druckträgerbahn 40 über die Schreibwalze 32 gelegt und an der Aufwickelwelle 28 befestigt, indem beispielsweise ein Anfangsabschnitt der Bahn auf die Aufwickelwelle 28 aufgewickelt wird. Man sieht, daß diese Maßnahmen in der in der Figur 6 dargestellten Stellung der Teile völlig ungehindert und bequem ausgeführt werden können. If a new supply roll 26 is to be inserted or if the printer has to be opened for another reason, the cover 22 is pivoted clockwise from the closed position shown in FIG. 3, and at the same time it also rotates the swivel frame 34 together with the platen roller 32 in a clockwise direction the service position shown in Figure 5 pivoted. In this position, the shaft journal 58 is released from the hook opening 54, so that the coupling between the swivel frame 34 and the cover 22 is released and the cover 22 can be pivoted from the intermediate position shown in FIG. 5 into the open position shown in FIG. 6 , In the service position of the swivel frame 34, printhead 60 and platen roller 32 are widely separated. The bearing trough 42 and the winding shaft 28 are freely accessible. The winding shaft 28 with the winding formed thereon can be removed from the bearing forks 30 and a new winding shaft 28 can be inserted. Furthermore, a new supply roll 26 is inserted into the storage trough 42 and the print carrier web 40 is placed over the platen roller 32 and on of the take-up shaft 28, for example by winding an initial portion of the web onto the take-up shaft 28. It can be seen that these measures can be carried out completely freely and comfortably in the position of the parts shown in FIG. 6.
