Definitions
- the invention relates to a method for heating and fixing an ink application, in particular a toner powder on a plate-shaped carrier, in which the applied on the coated top of the carrier ink application is fixed by the action of heat on the support, and an apparatus for performing the method.
- infrared radiation to heat and fix a paint application applied to a paper or sheet carrier is known in the art DE 198 57 044 A1 known.
- the short-wave infrared radiation has a typical emission temperature of 2000 to 2500 K.
- Paper has a low basis weight, which is generally less than 100 g / m 2 .
- toner fixation is from the EP 0 989 473 A2 known.
- the toner powder is fixed on the paper with an inductively heated roller.
- thin copy paper is heated relatively quickly, since it also has a basis weight of ⁇ 100 g / m 2 in the rule.
- Thick-walled plate-like materials such as glass or ceramic plates, plastic plates, etc., can not be readily heated in this way because they have a significantly higher basis weight and therefore a significantly higher heat capacity.
- a heat fusion device is also from the DE-A-22 61 116 known, wherein each leads an electrically heated plate in containers above and below a paper web for fixing a toner image with thermally uniform radiation.
- the energy input takes place both on the coated top of the carrier and on the uncoated underside of the carrier with different selectable admission of infrared radiation, hot air flow and Microwave radiation.
- the carrier transmits a portion of the impingement and absorbs a portion thereof.
- the application of pressure to the back of the support causes the material of the support to heat uniformly as a result of partial absorption and, on the other hand, increased absorption in the toner powder takes place at the interface between the application of paint and the support, resulting in a better melting of the toner powder -vers and thus leads to a better adhesion on the carrier.
- the energy input is also largely independent of Tonerbelegungsgrad and the type of toner powder, which is particularly advantageous for direct printing of different carrier materials with different toner powder, such as thermoplastic, duroplastic or ceramic toner powders.
- the infrared emitters extend over the entire paint application of the stationary carrier or they form a continuous line, which ensure a sufficient heating and fixing time with the speed of the carrier and its length.
- Partial reflectors concentrate the radiation onto the paint application and also direct radiation reflected by the support back onto the support.
- the partial reflectors associated with the coated upper side of the carrier can be combined to form a reflector unit.
- the process according to the invention is used, because the carried-through carrier 1 is acted upon on the coated upper side 1.1 and the uncoated rear side of the lower side 1.2 with an infrared radiation emanating from infrared emitters 3, on both Pages of the carrier 1 are arranged.
- infrared emitters 3 are in the same pitch but offset by half a pitch from each other the top and bottom 1.1 and 1.2 of the carrier 1 assigned.
- the carrier 1 is moved by transport rollers 2. The speed of this movement and the length of this "flow chamber" are tuned to ensure adequate irradiation time and fixation time.
- the infrared emitters 3 are each arranged in semicircular partial reflectors 4.1 and 4.2, so that a bundling of the radiation in the direction of the carrier 1 takes place and that radiation reflected by the carrier 1 is reflected back again.
- the partial reflectors 4.1 on the coated upper side 1.1 of the carrier 1 are combined to form a reflector unit 4, while on the non-coated underside 1.2 of the carrier 1, the partial reflectors 4.2 are always arranged between two transport rollers 2.
- the infrared emitters 3 are for example formed as a tube heaters, halogen lamps, quartz lamps, or carbon lamps whose radiation maximum between 0.8 ⁇ m and 5 ⁇ m, and in each case the emission temperatures of between 1000 K and 750 K are.
- the thickness of the carrier is to be chosen in the range between 3 mm and 8 mm. Glass or glass ceramic with a transmission> 20%, preferably> 50%, for the short-wave infrared radiation is particularly well suited as a carrier material. Other materials with sufficiently large transmission for infrared radiation can be used with equally good effect.
- the radiators are designed as ceramic radiators. These have a radiation maximum between 3.5 and 4 microns and a radiation temperature in the range between 500 and 600 ° C.
- the structural design with the transport rollers 2, the infrared emitters 3 and the partial reflectors 4.1 and 4.2 is practically the same.
- a hot air stream 10 is additionally passed over the inking dse carrier 1, which is held by a hot air blower 6 in a conduit system 5 in circulation.
- the partial reflectors 4.1 of the reflector unit 4 close inflow chambers 11, to which the hot air is supplied via supply lines 5.1.
- the hot air exits through air passage openings 7 of the partial reflectors 4.1 from the inflow chambers 11 and heats the paint on additionally.
- the reflector unit 4 has suction openings 8, via which the hot air is sucked into suction chambers 12.
- the suction chambers 12 the sucked air are passed through the filter 9 and the Ver contained impurities.
- the freed from impurities and cooled air passes via suction lines 5.2 back to the hot air blower 6, where it is supplied to the circulation circuit 5 after heating and pressure increase again.
- the application of additional heat to the ink application brings an improvement in the heating time and thus the toner fixation.
- the hot air blower 6 may be formed as a radial fan, which sucks axially the air from the suction lines 5.2 and heated radially feeds the feed lines 5.1.
- the method can also be carried out in a device designed as a receiving chamber without transport rollers.
- the partial reflectors 4.2 are then combined to form a reflector unit and the carrier 1 is brought into the receiving chamber and exposed for a predetermined time of the infrared radiation together with hot air stream and / or microwave radiation.
- the combination with hot air and / or microwave radiation can be selected as needed, taking into account material, thickness and transmittance of the carrier 1.
- the coated upper side 1.1 of the carrier 1 is additionally acted upon by a directed and bundled hot air stream 10.
- the carrier 1 is moved on transport rollers 2 on the stationary hot air blower 6, which is housed in a housing 15.
- the air flow generated by the hot air blower 6 is thereby still heated via a heater 13 and fed via a guide element 14 selectively to an outflow opening 16.
- the guide element 14 forms with the housing 15 an outflow channel 17 and a suction channel 18 for the air flow 10.
- a microwave chamber 24 is shown in addition, in which can be introduced via closure members 25 of the carrier 1 and removed. During the loading of the uncoated underside 1.2 of the carrier, the closure members 25 remain closed. The microwave chamber 24 is shielded to the outside, so that the microwave radiation occurs only in the interior.
- the transport of the carrier 1 in and out of the microwave chamber 24 take over transport rollers 2. Between the transport rollers 2 Mikrowellenklystrons 23 are arranged, which are controlled by a pyrometer 26. Pyrometers, especially those in the spectral range with wavelengths around 5.5 ⁇ m or im Range 7.5 to 8.2 ⁇ m sensitive, are particularly well suited for monitoring the surface temperature of glasses or glass ceramics. Due to the relatively good coupling of support materials of an aluminosilicate glass ceramic in high quartz mixed crystal modification (HQMK), temperature monitoring is particularly important in order to prevent overheating of the toner material and the carrier material.
- HQMK high quartz mixed crystal modification
- Pyrometers also offer the advantage that they are relatively insensitive to microwave radiation.

Description
Die Erfindung betrifft ein Verfahren zum Erwärmen und Fixieren eines Farbauftrages, insbesondere eines Tonerpulvers auf einem plattenförmigen Träger, bei dem der auf der beschichteten Oberseite des Trägers aufgebrachte Farbauftrag durch Wärmeeinwirkung auf dem Träger fixiert wird, sowie eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for heating and fixing an ink application, in particular a toner powder on a plate-shaped carrier, in which the applied on the coated top of the carrier ink application is fixed by the action of heat on the support, and an apparatus for performing the method.
Die Verwendung einer Infrarot-Strahlung zum Erwärmen und Fixieren eines auf einem Papier oder blattförmigen Träger aufgebrachten Farbauftrages ist aus der
Ein weiteres Verfahren zur Tonerfixierung ist aus der
Bei diesem bekannten Verfahren wird dünnes Kopierpapier relativ schnell aufgeheizt, da es in der Regel auch ein Flächengewicht von < 100 g/m2 aufweist. Dickwandige plattenförmige Materialien, wie Glas- oder Keramikplatten, Kunststoffplatten usw. können auf diese Art nicht so ohne Weiteres aufgeheizt werden, da sie ein deutlich höheres Flächengewicht und daher eine deutlich höhere Wärmekapazität aufweisen.In this known method thin copy paper is heated relatively quickly, since it also has a basis weight of <100 g / m 2 in the rule. Thick-walled plate-like materials, such as glass or ceramic plates, plastic plates, etc., can not be readily heated in this way because they have a significantly higher basis weight and therefore a significantly higher heat capacity.

Es ist Aufgabe der Erfindung, ein Verfahren zu schaffen, mit dem bzw. der schnell und effizient auf plattenförmigen Materialien mit hohem Flächengewicht Tonerpulver, insbesondere keramisches und duroplastisches Tonerpulver mit guter Haftung fixiert werden kann.It is an object of the invention to provide a method by which toner powder, in particular ceramic and thermosetting toner powder can be fixed with good adhesion quickly and efficiently to plate-shaped materials with a high basis weight.
Diese Aufgabe wird nach der Erfindung mit einem Verfahren nach Anspruch 1 gelöst. Verschiedene vorteilhafte Ausgestaltungen sind in den abhängigen Ansprüchen definiert.This object is achieved according to the invention with a method according to claim 1. Various advantageous embodiments are defined in the dependent claims.
Der Energieeintrag erfolgt dabei sowohl über die beschichtete Oberseite des Trägers als auch über die nicht beschichtete Unterseite des Trägers mit unterschiedlich wählbarer Beaufschlagung aus Infrarotstrahlung, Heissluftstrom und Mikrowellenstrahlung. Der Träger lässt einen Teil der Beaufschlagung durch und absorbiert einen Teil derselben. Die Beaufschlagung der Rückseite des Trägers bewirkt zum einen, dass durch teilweise Absorption sich das Material des Trägers gleichmäßig aufheizt, und zum anderen, dass an der Grenzfläche zwischen dem Farbauftrag und dem Träger eine erhöhte Absorption im Tonerpulver stattfindet, was zu einem besseren Aufschmelzen des Tonerpul-vers und damit auch zu einer besseren Haftung auf dem Träger führt. Der Energieeintrag ist auch weitgehend unabhängig vom Tonerbelegungsgrad und von der Art des Tonerpulvers, was bei Direktbedruckung unterschiedlicher Trägermaterialien mit unterschiedlichem Tonerpulver, wie thermoplastischen, duro-plastischen oder keramischen Tonerpulvern besonders vorteilhaft ist.The energy input takes place both on the coated top of the carrier and on the uncoated underside of the carrier with different selectable admission of infrared radiation, hot air flow and Microwave radiation. The carrier transmits a portion of the impingement and absorbs a portion thereof. The application of pressure to the back of the support, on the one hand, causes the material of the support to heat uniformly as a result of partial absorption and, on the other hand, increased absorption in the toner powder takes place at the interface between the application of paint and the support, resulting in a better melting of the toner powder -vers and thus leads to a better adhesion on the carrier. The energy input is also largely independent of Tonerbelegungsgrad and the type of toner powder, which is particularly advantageous for direct printing of different carrier materials with different toner powder, such as thermoplastic, duroplastic or ceramic toner powders.
Insbesondere die Infrarot-Strahler erstrecken sich über den gesamten Farbauftrag des stillstehenden Trägers oder sie bilden eine Durchlaufstrecke, die mit der Geschwindigkeit des Trägers und ihrer Länge eine ausreichende Aufheiz- und Fixierzeit gewährleisten. Teilreflektoren bündeln die Strahlung auf den Farbauftrag und richten auch vom Träger reflektierte Strahlung wieder auf den Träger. Dabei können die der beschichteten Oberseite des Trägers zugeordneten Teilreflektoren zu einer Reflektoreinheit vereinigt sein.In particular, the infrared emitters extend over the entire paint application of the stationary carrier or they form a continuous line, which ensure a sufficient heating and fixing time with the speed of the carrier and its length. Partial reflectors concentrate the radiation onto the paint application and also direct radiation reflected by the support back onto the support. In this case, the partial reflectors associated with the coated upper side of the carrier can be combined to form a reflector unit.

- a device with a hot air impingement of the coated top and
- Fig. 4

Bei der Durchlaufvorrichtung nach Fig. 1 wird das erfindungsgemäße Verfahren angewendet, denn der durchgeführte Träger 1 wird auf der beschichteten Oberseite 1.1 und der nicht beschichteten Rückseite der Unterseite 1.2 mit einer Infrarot-Strahlung beaufschlagt, die von Infrarot-Strahlern 3 ausgeht, die auf beiden Seiten des Trägers 1 angeordnet sind. Mehrere Infrarot-Strahler 3 sind in gleicher Teilung jedoch um eine halbe Teilung gegeneinander versetzt der Ober- und Unterseite 1.1 und 1.2 des Trägers 1 zugeordnet. Dabei wird der Träger 1 von Transportwalzen 2 bewegt. Die Geschwindigkeit dieser Bewegung und die Länge dieser "Durchlaufkammer" sind so abgestimmt, dass eine ausreichende Bestrahlungszeit und Fixierzeit gewährleistet wird. Die Infrarot-Strahler 3 sind jeweils in halbkreisförmigen Teilreflektoren 4.1 bzw. 4.2 angeordnet, so dass eine Bündelung der Strahlung in Richtung Träger 1 erfolgt und dass vom Träger 1 reflektierte Strahlung wieder zurück reflektiert wird. Die Teilreflektoren 4.1 auf der beschichteten Oberseite 1.1 des Trägers 1 sind zu einer Reflektoreinheit 4 vereinigt, während auf der nicht beschichteten Unterseite 1.2 des Trägers 1 die Teilreflektoren 4.2 stets zwischen zwei Transportwalzen 2 angeordnet sind.1, the process according to the invention is used, because the carried-through carrier 1 is acted upon on the coated upper side 1.1 and the uncoated rear side of the lower side 1.2 with an infrared radiation emanating from
Die Infrarot-Strahler 3 sind z.B. als Dunkelstrahler, Halogenstrahler, Quarz-strahler oder Carbonstrahler ausgebildet, deren Strahlungsmaximum zwischen 0,8 µm und 5 µm und jeweils deren Emissionstemperaturen zwischen 1000 K und 750 K liegen. Die Dicke des Trägers liegt im Bereich zwischen 3 mm und 8 mm gewählt werden. Glas oder Glaskeramik mit einer Transmission > 20 %, vorzugsweise > 50 %, für die kurzwellige Infrarot-Strahlung eignet sich besonders gut als Trägermaterial. Auch andere Materialien mit ausreichend großer Transmission für Infrarot-Strahlung sind mit gleich guter Wirkung verwendbar.The
In einem weiter bevorzugten Ausführungsbeispiel sind die Strahler als Keramikstrahler ausgebildet. Diese besitzen ein Strahlungsmaximum zwischen 3,5 und 4 µm und eine Strahlungstemperatur im Bereich zwischen 500 und 600°C.In a further preferred embodiment, the radiators are designed as ceramic radiators. These have a radiation maximum between 3.5 and 4 microns and a radiation temperature in the range between 500 and 600 ° C.
Beim Ausführungsbeispiel nach Fig. 2 ist der konstruktive Aufbau mit den Transportwalzen 2, den Infrarot-Strahlern 3 und den Teilreflektoren 4.1 und 4.2 praktisch gleich. Zur Erwärmung und Fixierung des Tonerpulvers auf der beschichteten Oberseite 1.1 des Trägers 1 wird zusätzlich jedoch noch ein Heißluftstrom 10 über den Farbauftrag dse Trägers 1 geleitet, der von einem Heißluftgebläse 6 in einem Leitungssystem 5 in Zirkulation gehalten wird. Die Teilreflektoren 4.1 der Reflektoreinheit 4 schließen Einströmkammern 11 ab, denen über Zuführleitungen 5.1 die Heißluft zugeführt wird. Die Heißluft tritt über Luftdurchtrittsöffnungen 7 der Teilreflektoren 4.1 aus den Einström-kammern 11 aus und heizt den Farbauftrag zusätzlich auf. Zwischen den Teilreflektoren 4.1 weist die Reflektoreinheit 4 Absaugöffnungen 8 auf, über die die Heißluft in Absaugkammern 12 eingesaugt wird. In den Absaugkammern 12 werden die eingesaugte Luft über Filter 9 geleitet und die enthaltenen Ver-unreinigungen zurückgehalten. Die von Verunreinigungen befreite und abgekühlte Luft gelangt über Absaugleitungen 5.2 wieder zum Heißluftgebläse 6 zurück, wo sie nach Erwärmung und Druckanhebung wieder dem Zirkulations-Kreislauf 5 zugeführt wird. Die Beaufschlagung des Farbauftrages mit zusätzlicher Heißluft bringt eine Verbesserung in der Aufheizzeit und damit auch der Tonerfixierung. Das Heißluftgebläse 6 kann als Radialgebläse ausgebildet sein, das axial die Luft aus den Absaugleitungen 5.2 ansaugt und aufgeheizt radial den Zuführleitungen 5.1 zuführt.In the embodiment of FIG. 2, the structural design with the
Wie erwähnt, kann das Verfahren auch in einer als Aufnahmekammer ausgebildeten Vorrichtung ohne Transportwalzen vorgenommen werden. Die Teilreflektoren 4.2 sind dann auch zu einer Reflektoreinheit vereinigt und der Träger 1 wird in die Aufnahmekammer gebracht und für eine vorgegebene Zeit der Infrarot-Strahlung zusammen mit Heißluftstrom und/oder einer Mikrowellenstrahlung ausgesetzt. Die Kombination mit Heißluft und/oder Mikrowellenstrahlung kann nach Bedarf gewählt werden, wobei Material, Dicke und Transmissionsgrad des Trägers 1 zu berücksichtigen sind.As mentioned, the method can also be carried out in a device designed as a receiving chamber without transport rollers. The partial reflectors 4.2 are then combined to form a reflector unit and the carrier 1 is brought into the receiving chamber and exposed for a predetermined time of the infrared radiation together with hot air stream and / or microwave radiation. The combination with hot air and / or microwave radiation can be selected as needed, taking into account material, thickness and transmittance of the carrier 1.
Bei dem Ausführungsbeispiel nach Fig. 3 wird die beschichtete Oberseite 1.1 des Trägers 1 zusätzlich mit einem gerichteten und gebündelten Heißluftstrom 10 beaufschlagt. Dabei wird der Träger 1 auf Transportrollen 2 an dem feststehenden Heißluftgebläse 6 vorbei bewegt, das in einem Gehäuse 15 untergebracht ist. Der vom Heißluftgebläse 6 erzeugte Luftstrom wird dabei noch über eine Heizung 13 erwärmt und über ein Leitelement 14 gezielt einer Ausströmöffnung 16 zugeführt. Das Leitelement 14 bildet mit dem Gehäuse 15 einen Ausströmkanal 17 und einen Einsaugkanal 18 für den Luftstrom 10.In the embodiment according to FIG. 3, the coated upper side 1.1 of the carrier 1 is additionally acted upon by a directed and bundled
In Fig. 4 ist zusätzlich eine Mikrowellenkammer 24 gezeigt, bei der über Verschlussorgane 25 der Träger 1 eingebracht und herausgenommen werden kann. Während der Beaufschlagung der nicht beschichteten Unterseite 1.2 des Trägers bleiben die Verschlussorgane 25 geschlossen. Die Mikrowellenkammer 24 ist nach außen abgeschirmt, so dass die Mikrowellenstrahlung nur im Innenraum auftritt. Der Transport des Trägers 1 in die und aus der Mikrowellenkammer 24 übernehmen Transportrollen 2. Zwischen den Transportrollen 2 sind Mikrowellenklystrons 23 angeordnet, die mittels eines Pyrometers 26 geregelt werden. Pyrometer, insbesondere solche, die im Spektralbereich mit Wellenlängen um die 5,5 µm bzw. im Bereich 7,5 bis 8,2 µm empfindlich sind, eignen sich besonders gut zur Überwachung der Oberflächentemperatur von Gläsern oder Glaskeramiken. Aufgrund der relativ guten Ankopplung von Trägermaterialien aus einer Alumosilikat-Glaskeramik in Hochquarzmischkristall-Modifikation (HQMK) ist eine Temperaturüberwachung besonders wichtig, um Überhitzungen des Tonermaterials und des Trägermaterials zu verhindern.In Fig. 4, a
Pyrometer bieten weiterhin den Vorteil, dass sie relativ unempfindlich bezüglich Mikrowellenstrahlung sind.Pyrometers also offer the advantage that they are relatively insensitive to microwave radiation.
