Definitions
- the invention relates to a good processing device with an ink printing device according to the preamble of patent claim 1.
- the good processing device is equipped with an ink printing device for producing impressions on a moving in a transport direction x print carrier.
- print substrate when referring to a print substrate, it is intended to exclude other print media, such as flat goods, mailpieces, envelopes, postcards, and the like, from being processed in a printing good processing apparatus having the claimed inventive features.
- the print carrier is pressed by means of a pressure device to a transport module of the ink printing device and transported during printing in a transport direction x.
- the ink printing device comprises a printing module.
- the latter has a print carriage with a cartridge holder for receiving a replaceable ink cartridge or an inkjet print head holder for receiving an inkjet printhead.
- the printing module is adapted to displace the single at least one 1 inch wide print-producing ink jet print head in a direction orthogonal to the transport direction x vertical z-direction of a Cartesian coordinate system and vice versa by means of a linear stepping motor, as long as the printing is interrupted.
- Another part of the printing module is referred to below as a carriage, wherein the carriage of the printing module is moved for the purpose of maintenance transverse to the transport direction x.
- the ink jet printhead is also moved in the y direction of the Cartesian coordinate system and vice versa.
- different positions in the y direction are provided, wherein the carriage is moved by means of another motor controlled by a control unit of the good processing device.
- DE102018110726.9 for example, a suitable driving method for a commodity processing apparatus having an ink-jet printhead will be described.
- the good processing device can be formed for example as a franking machine.
- a franking machine comes in contact with peripheral devices and with other mail processing equipment in a franking system, which is wholly or partly bought or rented by a customer.
- Each inkjet printhead may be composed of three modules. From the European patent EP 713 776 B1 For example, another structure of two of the three modules for an ink jet print head is known. However, such a construction leads to distortions in the printed image due to manufacturing tolerances, which must be compensated by an electronic control. For a multi-module non-interlaced ink jet print head, therefore, a method and an arrangement for tolerance compensation (US Pat. EP 921 008 B1 and EP 921 009 A1 ) developed. A more integrated 1 inch inkjet printhead was not available at the time. Recently, modern methods based on silicon wafer technology for producing the nozzles in a nozzle plate (side shooter principle) have made possible high precision even when printing a larger printing width (US Pat. EP 2 576 224 B1 ).
- a postage meter with two 1 ⁇ 2 inch ink jet printheads is known, but requires printing a control pattern. Since each of the two 1 ⁇ 2 inch inkjet printheads prints only one half of the franking imprint, aligning both imprint halves is required. Since the two 1 ⁇ 2 inch inkjet printheads are offset not only transversely to the direction of transport of the mail piece but also longitudinally in the transport direction of the mail piece, a "time delay" becomes necessary Time offset reached. From the position of the two impression halves of the printed image of a predetermined printed image, the change required for the alignment of the impression halves in the control of the printing heads can be made easily readable relative to each other.
- the control system prints a test pattern on a surface of the mail piece and ensures that the print data signals sent to the pair of ink jet cartridges are coordinated to produce a high quality print of the print image.
- setting the default time delay by a user of a postage meter to achieve a high quality impression is time consuming and varies from operator to operator.
- Each of the two 1 ⁇ 2 "inkjet printheads is part of each ink cartridge, which has a limited supply of ink. After replacing spent ink cartridges, ink cartridges filled with ink may be inserted into a print carriage of the printer module having a carriage that travels on two rails transversely to the direction of transport of the mailpiece.
- the postage meter machine includes an arrangement for repositioning the carriage by its transverse movement and a maintenance assembly.
- the latter can only be moved orthogonally to the transverse movement. It is driven by a separate motor and can be moved in the transport direction and opposite to this.
- the maintenance assembly can be approached by a slotted guide to the printheads when the carriage is positioned in a maintenance position.
- the maintenance assembly and its drive means thus have no simple structure. Also, in a printing position, the pitch of the printheads over the print medium can not be changed. This is disadvantageous if the print carrier has no smooth, but a coarse textured or wavy surface.
- a box-shaped unit is equipped with a feed table having at the top an opening for the pressure elements of a pressure device, wherein the pressure elements are removably arranged, which facilitates their maintenance.
- the box-shaped unit is arranged in an operating position below the printing device of the franking machine and can be removed from this position for the purpose of maintenance.
- a mechanical connecting element is arranged at the back of the box-shaped assembly. Once an internal lock is released, the box-shaped assembly slides drawer-like on two guide rails forward and can be completely removed.
- the box-shaped unit can be removed, for example, for lifting the dust.
- ink-contaminable assemblies whose replacement requires opening the security housing of the postage meter required.
- a print carrier for producing impressions is pressed by means of a pressure device to an ink printing device which contains a transport module which transports the print carrier in a transport direction x during printing.
- the inkjet printing device has a print carriage with at least one replaceable ink cartridge.
- the at least one 1 ⁇ 2 inch ink cartridge is equipped with an ink jet print head which can be moved in the y direction and thus transversely to the transport direction x for the purpose of maintenance by means of the print carriage.
- franking machines are either sold or leased to customers. Each postage meter is updated to a next customer prior to its subsequent rental after being returned by a first customer.
- the need of future customers for a cheap modern printing technology in the franking machine could be taken into account.
- this would require a considerable effort in the reconstruction of the existing franking machines and it would therefore be desirable to keep the effort as low as possible.
- a franking machine in which all the ink-contaminable assemblies are arranged in the non-security areas of the franking machine.
- This has the advantage of having a postage meter re-leased to a customer should be easier to retrofit or can be maintained without opening the security housing of the franking machine is necessary.
- One of the non-safety areas again lies within a box-shaped module of the franking machine and another is accessible via a closable opening in a bottom plate of the housing lower part of the franking machine.
- the PostBase® post card rack has space issues when used with a 1-inch inkjet print head or cartridge with such a 1-inch inkjet print head because the rack was originally designed for two-1 ⁇ 2-inch Hewlett Packart ink cartridges only.
- the object is to eliminate the deficiencies of the known solutions, to improve the precision in printing an impression by means of an ink jet print head, to increase the accuracy of adjusting the distance of the ink jet print head over the print carrier and to further simplify the maintenance device of the printing device of the good processing device.
- the existing print mechanics should continue to be used.
- a subtask is to fix the space problem when using a 1 inch inkjet print head in a PostBase® postage meter machine.
- the space problem is to be solved essentially by removably constructed electro-mechanical and mechanical components.
- Another subtask is to allow for manual adjustment of the movement mechanics when the postage meter machine is de-energized and a 1 inch printhead motor method is not possible to position the print carriage at an appropriate position that permits replacement of the 1 inch ink printhead.
- An ink printing apparatus of the good processing apparatus includes a printing module.
- the print module is used to produce impressions on a moving print carrier and comprises a single ink jet printhead or ink cartridge with an ink jet printhead.
- the inkjet printing device allows movement of the inkjet printhead in two dimensions as long as printing is interrupted.
- the printing module is designed to displace the single ink-jet printhead in a y-direction transverse to the transport direction x and opposite thereto and in an orthogonal z-direction and opposite thereto.
- the stationary inkjet print head of the good processing apparatus which is stationary during printing, permits an impression at least 1 inch wide on a print carrier which is moved in the transport direction x during printing.
- the printing module according to the invention has a movable in the y-direction carriage and a subsequent print carriage part of the printing module, which is mounted vertically movable on the carriage.
- the print carriage has either a cartridge holder and a single plug-in ink cartridge or ink print head holder and an ink jet print head.
- a known print carriage of the PostBase® postage meter machine requires at least a cartridge holder and a carriage, which is movably mounted in the y-direction on two guide rods.
- the guide rods are linear support and guide elements of the carriage.
- the guide rods are arranged in a frame transversely to the transport direction x of the print carrier, lie parallel to one another at a constant distance which extends in the transport direction x and extend lengthwise in a direction orthogonal to the transport direction x of a Cartesian coordinate system.
- slide and print carriage are mounted separately movable in two orthogonal directions.
- a moving mechanism for vertically raising and lowering the ink jet printing head in the z direction and opposite thereto is provided so as to allow vertical movement thereof parallel to the z direction of the Cartesian coordinate system.
- the ink jet printhead is a component of the single ink cartridge, such as an ink cartridge with a 1 inch ink printhead, which is below a closable ink jet Flap mounted replaceably in an opening of a housing upper shell of the good processing device and accessible from above.
- the 1 inch ink jet print head can be prevented from drying out by sealing with a properly trained cleaning and sealing station (RDS).
- RDS has a stationary sealing cap and is interchangeably mounted in a housing lower shell of the good processing device via a closable maintenance opening.
- the 1 inch inkjet printhead can be coupled to the RDS due to the motion mechanics without the need to raise the RDS. This advantageously simplifies the structure of the maintenance station (RDS).
- the distance of the 1-inch inkjet printhead to a stationary service station (wiper lip) can be set different and highly accurate.
- the good processing device is, for example, a franking machine. All ink-contaminable assemblies are further arranged in the non-security areas of the franking machine.
- the modular arrangement of an ink reservoir corresponding to the ink reservoir takes place within the postage meter on a position located between the service station and the bottom plate of the housing base, all Tintenschmuetzbaren assemblies are accessible via a shaft-shaped opening in the bottom of the housing lower shell of the postage meter.
- the service station can also be replaced via the aforementioned shaft-shaped opening. Maintenance costs are reduced because only one service station is assigned to the print module with a single 1-inch wide inkjet printhead.
- the precision of printing an impression is further enhanced by the use of the single, at least 1 inch wide, inkjet printhead.
- the problems with aligning imprint halves of a printed image apparently disappear when using two 1 ⁇ 2 inch inkjet printheads instead Only a single inkjet printhead with a printing width of 1 inch is used.
- the inkjet printhead can be positioned accurately not only transversely to the transport direction of the print carrier, but also at a distance from the surface to be printed on the print carrier by means of a movement mechanism.
- the advantageous accuracy of the adjustment of the distance of the 1 inch ink jet print head over the print carrier also contributes to the improvement of the impression.
- the movement mechanism for raising and lowering the 1-inch ink-jet printhead comprises on the one hand means for moving the 1-inch ink-jet printhead in a direction z orthogonal to the transport direction x of the cartesian coordinate system and on the other hand means for manual adjustment of the distance of the 1-inch inkjet printhead from the Surface of the on-page print carrier.
- the movement mechanism is equipped with a lifting bar and with a balancing shaft whose longitudinal axis is aligned in the y-direction, ie transversely to a transport direction x of a printing medium.
- the movement mechanism allows lifting and lowering of the print carriage, wherein the lifting bar remains aligned parallel to the y-direction, ie transversely to the transport direction x.
- At both ends of the balance shaft each pinion force and are positively attached.
- the racks of the mounted lifting beam run in guides, wherein the guides are formed in a carrier for the movement mechanics and that the balance shaft is rotatably mounted on the carrier, wherein the racks of the balance shaft opposite the x-direction spaced but are arranged so close that on both sides of the balance shaft, the teeth of the racks and the teeth of the pinion engage each other at one point without play.
- One of the two racks is at the first end of the lifting bar and the other of the racks is at a distance of 60% to 80% of the first end, preferably in the distance range 2/3 to 70% of the length L of Lifting beam integrally formed.
- the load beam has a length L which is greater than the length of the carrier, that a first end of the carrier is aligned with the first end of the lifting beam and that the second end of the carrier at a distance of 70% 80% of the length L of the lifting bar is located from the first end, so that the lifting bar projects beyond the carrier in front.
- the lifting beam is applied by spring force and / or by gravity to the means for motorized method.
- the motoring means are mounted to the carrier within a y-directional space between the two racks.
- Means such as a linear stepping motor with integrated lifting mechanism are provided for the motorized method, wherein the integrated lifting mechanism is self-locking and has a lifting rod, which is arranged parallel to the z-direction and stepwise extendable to a predetermined adjustment length in the z-direction.
- the bottom of the lower housing shell of the franking machine additionally has a further opening, via which a tool suitable for this purpose can be introduced in order to actuate the means for manual adjustment of the movement mechanism.
- the means for manual adjustment are formed on the underside of a support of the movement mechanism and have a cylindrical rotary latch holder with a central opening at a distance from the carrier against the z-direction and the means for locking the vertical adjustment position.
- the manual adjustment means are spaced from the motoring means of the 1 inch ink jet printhead in the y direction of the Cartesian coordinate system.
- the means for locking the vertical adjustment position are integrated in the means for manual adjustment. They include a rotary latch, which can be adjusted with a tool.
- each adjustment position a predetermined Distance of the 1 inch inkjet printhead against the surface of the print carrier to be printed in the z-direction corresponds.
- the motion mechanism allows lifting and lowering of the 1 inch inkjet print head. This has the advantage that the maintenance station can be designed simply because it does not need to be lowered or raised.
- a well-known good processing device - seen from the front - transports print media from left to right during printing.

Das würde jedoch einen erheblichen Aufwand beim Umbau der bestehenden Frankiermaschinen erfordern und es wäre deshalb wünschenswert, den Aufwand dafür so gering wie möglich zu halten.In practice, franking machines are either sold or leased to customers. Each postage meter is updated to a next customer prior to its subsequent rental after being returned by a first customer. The need of future customers for a cheap modern printing technology in the franking machine could be taken into account. However, this would require a considerable effort in the reconstruction of the existing franking machines and it would therefore be desirable to keep the effort as low as possible.
Aus dem deutschen Gebrauchsmuster
Die Aufgabe besteht darin, die Mängel der bekannten Lösungen zu beseitigen, die Präzision beim Drucken eines Abdruckes mittels eines Tintenstrahldruckkopfes zu verbessern, die Genauigkeit der Einstellung des Abstandes des Tintenstrahldruckkopfes über dem Druckträger zu erhöhen und die Wartungvorrichtung der Druckvorrichtung des Gutverarbeitungsgeräts weiter zu vereinfachen. Dabei soll die vorhandene Druckmechanik im Wesentlichen weiter benutzt werden. Eine Teilaufgabe besteht in einem Beheben des Platzproblems bei Einsatz eines 1 Zoll-Tintendruckkopfes in einer Frankiermaschine vom Typ PostBase®. Das Platzproblem soll im Wesentlichen durch herausnehmbar aufgebaute elektro-mechanische und mechanische Bauteile gelöst werden.The object is to eliminate the deficiencies of the known solutions, to improve the precision in printing an impression by means of an ink jet print head, to increase the accuracy of adjusting the distance of the ink jet print head over the print carrier and to further simplify the maintenance device of the printing device of the good processing device. At the same time, the existing print mechanics should continue to be used. A subtask is to fix the space problem when using a 1 inch inkjet print head in a PostBase® postage meter machine. The space problem is to be solved essentially by removably constructed electro-mechanical and mechanical components.
Eine andere Teilaufgabe besteht in einem Ermöglichen einer Handverstellung der Bewegungsmechanik, wenn die Frankiermaschine stromlos ist und ein motorischen Verfahren des 1 Zoll-Druckkopfes nicht möglich ist, um den Druckwagen in eine geeignete Position zu bringen, welche ein Auswechseln des 1 Zoll-Tintendruckkopfes erlaubt.Another subtask is to allow for manual adjustment of the movement mechanics when the postage meter machine is de-energized and a 1 inch printhead motor method is not possible to position the print carriage at an appropriate position that permits replacement of the 1 inch ink printhead.
Die Aufgabe wird mit den Merkmalen eines Gutverarbeitungsgeräts nach dem Patentanspruch 1 gelöst.The object is achieved with the features of a good processing device according to
Eine Tintendruckvorrichtung des Gutverarbeitungsgeräts umfasst ein Druckmodul. Das Druckmodul dient zur Erzeugung von Abdrucken auf einen bewegten Druckträger und weist einen einzigen Tintenstrahldruckkopf bzw. eine Tintenkartusche mit einem Tintenstrahldruckkopf auf. Die Tintendruckvorrichtung ermöglicht eine Bewegung des Tintenstrahldruckkopfes in zwei Dimensionen, solange das Drucken unterbrochen wird. Das Druckmodul ist entsprechend ausgebildet, den einzigen Tintenstrahldruckkopf in eine y-Richtung quer zur Transportrichtung x und entgegengesetzt dazu sowie in eine orthogonale z-Richtung und entgegen-gesetzt dazu zu verschieben. Der während des Druckens stationäre einzige Tintenstrahldruckkopf des Gutverarbeitungsgeräts erlaubt einen mindestens 1 Zoll breiten Abdruck auf einen Druckträger, der während des Druckens in Transport-richtung x bewegt wird.An ink printing apparatus of the good processing apparatus includes a printing module. The print module is used to produce impressions on a moving print carrier and comprises a single ink jet printhead or ink cartridge with an ink jet printhead. The inkjet printing device allows movement of the inkjet printhead in two dimensions as long as printing is interrupted. The printing module is designed to displace the single ink-jet printhead in a y-direction transverse to the transport direction x and opposite thereto and in an orthogonal z-direction and opposite thereto. The stationary inkjet print head of the good processing apparatus, which is stationary during printing, permits an impression at least 1 inch wide on a print carrier which is moved in the transport direction x during printing.
Das erfindungsgemäße Druckmodul weist einen in y-Richtung beweglichen Schlitten und einen nachfolgend Druckwagen genannten Teil des Druckmoduls auf, der am Schlitten vertikal beweglich montiert ist. Der Druckwagen weist entweder einen Kartuschenhalter und eine einzige einsteckbare Tintenkartusche oder einen Tintendruckkopfhalter und einen Tintenstrahldruckkopf auf.The printing module according to the invention has a movable in the y-direction carriage and a subsequent print carriage part of the printing module, which is mounted vertically movable on the carriage. The print carriage has either a cartridge holder and a single plug-in ink cartridge or ink print head holder and an ink jet print head.
Ein bekannter Druckwagen der Frankiermaschine vom Typ PostBase® benötigt mindestens einen Kartuschenhalter und einen Schlitten, der in y-Richtung beweglich auf zwei Führungsstangen montiert ist. Die Führungsstangen sind lineare Trag- und Führungselemente des Schlittens. Die Führungsstangen sind in einem Gestell quer zu der Transportrichtung x der Druckträger angeordnet, liegen parallel zueinander in einem konstanten Abstand, der sich in die Transportrichtung x erstreckt und erstrecken sich der Länge nach in einer zur Transportrichtung x orthogonalen Richtung y eines kartesischen Koordinatensystems.A known print carriage of the PostBase® postage meter machine requires at least a cartridge holder and a carriage, which is movably mounted in the y-direction on two guide rods. The guide rods are linear support and guide elements of the carriage. The guide rods are arranged in a frame transversely to the transport direction x of the print carrier, lie parallel to one another at a constant distance which extends in the transport direction x and extend lengthwise in a direction orthogonal to the transport direction x of a Cartesian coordinate system.
Im erfindungsgemäßen Druckmodul sind Schlitten und Druckwagen separat voneinander in zwei orthogonale Richtungen beweglich montiert.In the printing module according to the invention slide and print carriage are mounted separately movable in two orthogonal directions.
Im Gutverarbeitungsgerät ist eine Bewegungsmechanik zum vertikalen Anheben und Absenken des Tintenstrahldruckkopfes in z-Richtung und entgegengesetzt dazu vorgesehen, so dass eine vertikale Bewegung desselben parallel zur z-Richtung des kartesischen Koordinatensystems ermöglicht wird. Der Tintenstrahldruckkopf ist ein Bestandteil der einzigen Tintenkartusche, beispielsweise einer Tintenkartusche mit einem 1-Zoll-Tintendruckkopf, die unter einer verschließbaren Klappe in einer Öffnung einer Gehäuseoberschale des Gutverarbeitungsgeräts auswechselbar montiert und von oben zugänglich ist. Mittels der in einem Gestell des Gutverarbeitungsgeräts montierten Bewegungsmechanik kann ein Anheben und ein Absenken des 1 Zoll-Tintenstrahldruckkopfes gegenüber der Wartungsstation oder dem zu bedruckenden Druckträger und zum Kartuschenwechseln realisiert werden. Der 1 Zoll-Tintenstrahldruckkopf kann durch Abdichtung mittels einer in einer geeigneten Weise ausgebildeten Reinigungs- und Dicht-Station (RDS) vor einer Austrocknung geschützt werden. Die RDS weist eine stationäre Dichtkappe auf und ist über eine verschließbare Wartungsöffnung auswechselbar in einer Gehäuseunterschale des Gutverarbeitungsgeräts montiert. Der 1 Zoll-Tintenstrahldruckkopf kann aufgrund der Bewegungsmechanik mit der RDS gekoppelt werden, ohne dass ein Anheben der RDS erforderlich ist. Dadurch vereinfacht sich vorteilhaft der Aufbau der Wartungsstation (RDS). Außerdem läßt sich der Abstand des 1 Zoll-Tintenstrahldruckkopfes zu einer stationären Wartungsstation (Wischlippe) unterschiedlich und hoch genau einstellen.In the good processing apparatus, a moving mechanism for vertically raising and lowering the ink jet printing head in the z direction and opposite thereto is provided so as to allow vertical movement thereof parallel to the z direction of the Cartesian coordinate system. The ink jet printhead is a component of the single ink cartridge, such as an ink cartridge with a 1 inch ink printhead, which is below a closable ink jet Flap mounted replaceably in an opening of a housing upper shell of the good processing device and accessible from above. By means of the movement mechanism mounted in a frame of the good processing device, raising and lowering of the 1-inch ink-jet printhead with respect to the service station or the print carrier to be printed and the cartridge replacement can be realized. The 1 inch ink jet print head can be prevented from drying out by sealing with a properly trained cleaning and sealing station (RDS). The RDS has a stationary sealing cap and is interchangeably mounted in a housing lower shell of the good processing device via a closable maintenance opening. The 1 inch inkjet printhead can be coupled to the RDS due to the motion mechanics without the need to raise the RDS. This advantageously simplifies the structure of the maintenance station (RDS). In addition, the distance of the 1-inch inkjet printhead to a stationary service station (wiper lip) can be set different and highly accurate.
Das Gutverarbeitungsgerät ist beispielsweise eine Frankiermaschine. Alle tintenverschmutzbaren Baugruppen sind weiterhin in den Nichtsicherheitsbereichen der Frankiermaschine angeordnet. Die modulare Anordnung eines dem Tintenreservoir entsprechenden Tintenauffangbehälters erfolgt innerhalb der Frankiermaschine auf einer zwischen der Wartungsstation und der Bodenplatte des Gehäuseunterteils gelegenen Position, wobei alle tintenverschmutzbaren Baugruppen über eine schachtförmige Öffnung im Boden der Gehäuseunterschale der Frankiermaschine zugänglich sind. Die Wartungsstation kann ebenfalls über die vorgenannte schachtförmige Öffnung ausgewechselt werden. Der Wartungsaufwand verringert sich, weil dem Druckmodul mit einem einzigen 1 Zoll breiten Tintenstrahldruckkopf nur noch eine einzige Wartungsstation zugeordnet ist.The good processing device is, for example, a franking machine. All ink-contaminable assemblies are further arranged in the non-security areas of the franking machine. The modular arrangement of an ink reservoir corresponding to the ink reservoir takes place within the postage meter on a position located between the service station and the bottom plate of the housing base, all Tintenschmuetzbaren assemblies are accessible via a shaft-shaped opening in the bottom of the housing lower shell of the postage meter. The service station can also be replaced via the aforementioned shaft-shaped opening. Maintenance costs are reduced because only one service station is assigned to the print module with a single 1-inch wide inkjet printhead.
Die Präzision beim Drucken eines Abdruckes wird durch die Verwendung des einzigen mindestens 1 Zoll breiten Tintenstrahldruckkopfes weiter erhöht. Gegenüber einer Verwendung von zwei ½ Zoll Tintenstrahldruckköpfen in einem Druckmodul entfallen offensichtlich die Probleme mit der Ausrichtung von Abdruckhälften eines Druckbildes, wenn statt zweier ½ Zoll Tintenstrahldruckköpfe nur ein einziger Tintenstrahldruckkopf mit einer Druckbreite von 1 Zoll eingesetzt wird.The precision of printing an impression is further enhanced by the use of the single, at least 1 inch wide, inkjet printhead. As opposed to using two ½ inch inkjet printheads in a print module, the problems with aligning imprint halves of a printed image apparently disappear when using two ½ inch inkjet printheads instead Only a single inkjet printhead with a printing width of 1 inch is used.
Der Tintenstrahldruckkopf kann nicht nur quer zur Transportrichtung der Druckträger, sondern außerdem im Abstand zu der zu bedruckenden Oberfläche des Druckträgers mittels einer Bewegungsmechanik genau positioniert werden. Die vorteilhafte Genauigkeit der Einstellung des Abstandes des 1 Zoll-Tintendruckkopfes über dem Druckträger trägt ebenfalls zur Verbesserung des Abdruckes bei. Die Bewegungsmechanik zum Anheben und Absenken des 1 Zoll-Tintenstrahldruckkopfes weist einerseits Mittel zum motorischen Verfahren des 1 Zoll-Tintenstrahldruckkopfes in einer zur Transportrichtung x orthogonalen Richtung z des kartesischen Koordinatensystems und entgegengesetzt dazu sowie andererseits Mittel zur Handverstellung des Abstandes des 1 Zoll-Tintenstrahldruckkopfes gegenüber der Oberfläche des auf der Seite liegenden Druckträgers auf.The inkjet printhead can be positioned accurately not only transversely to the transport direction of the print carrier, but also at a distance from the surface to be printed on the print carrier by means of a movement mechanism. The advantageous accuracy of the adjustment of the distance of the 1 inch ink jet print head over the print carrier also contributes to the improvement of the impression. The movement mechanism for raising and lowering the 1-inch ink-jet printhead comprises on the one hand means for moving the 1-inch ink-jet printhead in a direction z orthogonal to the transport direction x of the cartesian coordinate system and on the other hand means for manual adjustment of the distance of the 1-inch inkjet printhead from the Surface of the on-page print carrier.
Es ist vorgesehen, dass die Bewegungsmechanik mit einem Lasthebebalken und mit einer Ausgleichswelle ausgestattet ist, deren Längsachse in y-Richtung, also quer zu einer Transportrichtung x eines Druckträgers ausgerichtet ist. Die Bewegungsmechanik erlaubt ein Anheben und Absenken des Druckwagens, wobei der Lasthebebalken parallel zur y-Richtung, also quer zu der Transportrichtung x ausgerichtet bleibt. An beiden Enden der Ausgleichswelle sind jeweils Zahnritzel kraft- und formschlüssig befestigt. An dem Lasthebebalken sind Zahnstangen entgegen der z-Richtung, also in Richtung der Schwerkraft vom Lasthebebalken abstehend angebracht bzw. angeformt, wobei die Zahnstangen des montierten Lasthebebalkens in Führungen laufen bzw. gleiten, wobei die Führungen in einem Träger für die Bewegungsmechanik eingeformt sind und dass die Ausgleichswelle an dem Träger drehbar montiert ist, wobei die Zahnstangen von der Ausgleichswelle entgegen der x-Richtung beabstandet jedoch so nahe angeordnet sind, dass beidseitig der Ausgleichswelle die Zähne der Zahnstangen und die Zähne der Zahnritzel jeweils an einer Stelle spielfrei ineinander greifen. Eine der beiden Zahnstangen ist an dem ersten Ende des Lasthebebalkens und die jeweils andere der Zahnstangen ist in einem Abstand von 60% bis 80% von dem ersten Ende, vorzugsweise im Abstandsbereich 2/3 bis 70% der Länge L des Lasthebebalkens angeformt. Es ist vorgesehen, dass der Lasthebebalken eine Länge L aufweist, die größer ist, als die Länge des Trägers, dass ein erstes Ende des Trägers mit dem ersten Ende des Lasthebebalkens fluchtet und dass sich das zweite Ende des Trägers in einem Abstand von 70% bis 80% der Länge L des Lasthebebalkens von dem ersten Ende entfernt befindet, so dass der Lasthebebalken den Träger vorne überragt. Der Lasthebebalken liegt durch Federkraft und/oder aufgrund der Schwerkraft an den Mitteln zum motorischen Verfahren an. Die Mittel zum motorischen Verfahren sind innerhalb eines sich in y-Richtung erstreckenden Zwischenraumes zwischen den beiden Zahnstangen an dem Träger montiert. Zum motorischen Verfahren sind Mittel, wie beispielsweise ein Linearschrittmotor mit integrierter Hebemechanik vorgesehen, wobei die integrierte Hebemechanik selbsthemmend ausgebildet ist und eine Hubstange aufweist, welche zu der z-Richtung parallel liegend angeordnet und auf eine vorbestimmte Verstelllänge in z-Richtung schrittweise ausfahrbar ist.It is envisaged that the movement mechanism is equipped with a lifting bar and with a balancing shaft whose longitudinal axis is aligned in the y-direction, ie transversely to a transport direction x of a printing medium. The movement mechanism allows lifting and lowering of the print carriage, wherein the lifting bar remains aligned parallel to the y-direction, ie transversely to the transport direction x. At both ends of the balance shaft each pinion force and are positively attached. On the lifting beam racks against the z-direction, ie in the direction of gravity from the lifting beam abstehend mounted or molded, the racks of the mounted lifting beam run in guides, wherein the guides are formed in a carrier for the movement mechanics and that the balance shaft is rotatably mounted on the carrier, wherein the racks of the balance shaft opposite the x-direction spaced but are arranged so close that on both sides of the balance shaft, the teeth of the racks and the teeth of the pinion engage each other at one point without play. One of the two racks is at the first end of the lifting bar and the other of the racks is at a distance of 60% to 80% of the first end, preferably in the
In Kombination mit den Mitteln zur Handverstellung sind Mittel zur Arretierung der vertikalen Verstellposition vorgesehen. Zur Handverstellung weist der Boden der Gehäuseunterschale der Frankiermaschine eine weitere Öffnung zusätzlich auf, über welche ein dazu geeignetes Werkzeug eingeführt werden kann, um die Mittel zur Handverstellung der Bewegungsmechanik zu betätigen.In combination with the means for manual adjustment means for locking the vertical adjustment position are provided. For manual adjustment, the bottom of the lower housing shell of the franking machine additionally has a further opening, via which a tool suitable for this purpose can be introduced in order to actuate the means for manual adjustment of the movement mechanism.
Die Mittel zur Handverstellung sind auf der Unterseite eines Trägers der Bewegungsmechanik angeformt und weisen einen zylinderförmigen Drehriegelhalter mit einer zentralen Öffnung in einem Abstand zum Träger entgegen der z-Richtung sowie die Mittel zur Arretierung der vertikalen Verstellposition auf. Die Mittel zur Handverstellung sind in y-Richtung des kartesischen Koordinatensystems von den Mitteln zum motorischen Verfahren des 1 Zoll-Tintenstrahldruckkopfes beabstandet. Die Mittel zur Arretierung der vertikalen Verstellposition sind in dem Mittel zur Handverstellung integriert. Sie umfassen einen Drehriegel, der mit einem Werkzeug verstellt werden kann.The means for manual adjustment are formed on the underside of a support of the movement mechanism and have a cylindrical rotary latch holder with a central opening at a distance from the carrier against the z-direction and the means for locking the vertical adjustment position. The manual adjustment means are spaced from the motoring means of the 1 inch ink jet printhead in the y direction of the Cartesian coordinate system. The means for locking the vertical adjustment position are integrated in the means for manual adjustment. They include a rotary latch, which can be adjusted with a tool.
Bei einem motorischen Verfahren des Lasthebebalkens können mehrere unterschiedliche Verstellpositonen und bei der Handverstellung zwei unterschiedliche Verstellpositonen erreicht werden, wobei jede Verstellposition einem vorbestimmten Abstand des 1 Zoll-Tintenstrahldruckkopfes gegenüber der zu bedruckenden Oberfläche des Druckträgers in z-Richtung entspricht. Die Bewegungsmechanik erlaubt ein Anheben und Absenken des 1 Zoll-Tintendruckkopfes. Das hat den Vorteil, dass die Wartungsstation einfach ausgebildet sein kann, da diese weder abgesenkt noch angehoben werden braucht.In a motorized method of the lifting bar several different Verstellpositonen and the manual adjustment two different Verstellpositonen can be achieved, each adjustment position a predetermined Distance of the 1 inch inkjet printhead against the surface of the print carrier to be printed in the z-direction corresponds. The motion mechanism allows lifting and lowering of the 1 inch inkjet print head. This has the advantage that the maintenance station can be designed simply because it does not need to be lowered or raised.

Ein bekanntes Gutverarbeitungsgerät - von vorn gesehen - transportiert Druckträger von links nach rechts während des Bedruckens. Dabei bedeuten der Begriff "rechts" in Transportrichtung x eines - nicht dargestellten - Druckträgers bzw. stromabwärts gelegen und der Begriff "links" bedeutet entgegen der Transportrichtung x eines - nicht dargestellten - Druckträgers bzw. stromaufwärts gelegen. Es bedeuten "hinten" in y-Richtung sowie "oben" in z-Richtung eines kartesischen Koordinatensystems gelegen. Das Ausführungsbeispiel geht von einem derartigen Gutverarbeitungsgerät aus. Damit sollen aber solche Gutverarbeitungsgeräte nicht ausgeschlossen werden, die Druckträger von rechts nach links während des Bedruckens transportieren.A well-known good processing device - seen from the front - transports print media from left to right during printing. The term "right" in the transport direction x of a - not shown - print carrier or downstream located and the term "left" means contrary to the transport direction x - a - not shown - print carrier or upstream located. It means "back" in the y-direction and "up" in the z-direction of a Cartesian coordinate system. The embodiment is based on such a good processing device. However, this should not exclude such good processing equipment that transport the print carrier from right to left during printing.
Bei einer perspektivischen Darstellung von hinten sind die Begriffe "rechts" und "links" vertauscht. Deshalb werden nachfolgend die Begriffe "stromabwärts" und "stromaufwärts" verwendet.In a perspective view from behind the terms "right" and "left" are reversed. Therefore, the terms "downstream" and "upstream" are used below.
