Title
(DE) DRUCKMASCHINE MIT AUFLADUNGSEINRICHTUNG
(EN) PRINTING MACHINE WITH CHARGING DEVICE
(FR) MACHINE D'IMPRESSION À DISPOSITIF DE CHARGE
Abstract
(DE) Die Erfindung betrifft eine Druckmaschine (01), mit einem Auflageelement (07), das eine umlaufend bewegbare und für einen Kontakt mit einem Bedruckstoff (02) vorgesehenen Kontaktoberfläche (08) aufweist, wobei die Druckmaschine (01) einen Tintenstrahldruckkopf (09) aufweist, dessen Ausstoßöffnung (12) auf das Auflageelement (07) ausgerichtet angeordnet ist und wobei die Druckmaschine (01) eine Aufladungseinrichtung (03) aufweist, die eine Aufladungselektrode (04) aufweist, die auf die Kontaktoberfläche (08) ausgerichtet angeordnet ist und wobei die Aufladungseinrichtung (03) eine Gegenelektrode (06) aufweist und wobei die Kontaktoberfläche (08) zumindest teilweise zwischen der Aufladungselektrode (04) und der Gegenelektrode (06) angeordnet ist und wobei ein kleinster Abstand (a) zwischen der Aufladungselektrode (04) und der Kontaktoberfläche (08) größer ist als ein kleinster Abstand (b) zwischen einer Ausstoßöffnung (12) des zumindest einen ersten Druckkopfs (09) und der Kontaktoberfläche (08).
(EN) The invention relates to a printing machine (01), with a support element (07), which has a contact surface (08) which can be moved in circulation and is provided for a contact with a printing material (02), wherein: the printing machine (01) has an inkjet print head (09), the discharge opening (12) of which is arranged so as to be directed toward the support element (07); the printing machine (01) has a charging device (03), which has a charging electrode (04) arranged so as to be directed toward the contact surface (08); the charging device (03) has a counter electrode (06); the contact surface (08) is at least partially arranged between the charging electrode (04) and the counter electrode (06); and a minimum distance (a) between the charging electrode (04) and the contact surface (08) is greater than a minimum distance (b) between a discharge opening (12) of the at least one first print head (09) and the contact surface (08).
(FR) L'invention concerne une machine d'impression (01), avec un élément de support (07) qui a une surface de contact (08) qui peut être déplacée en circulation et qui est prévue pour un contact avec un matériau d'impression (02), dans laquelle : la machine d'impression (01) a une tête d'impression à jet d'encre (09), dont l'ouverture de décharge (12) est disposée de façon à être dirigée vers l'élément de support (07) ; la machine d'impression (01) a un dispositif de charge (03), qui a une électrode de charge (04) disposée de façon à être dirigée vers la surface de contact (08) ; le dispositif de charge (03) a une contre-électrode (06) ; la surface de contact (08) est au moins partiellement disposée entre l'électrode de charge (04) et la contre-électrode (06) ; et une distance minimale (a) entre l'électrode de charge (04) et la surface de contact (08) est supérieure à une distance minimale (b) entre une ouverture de décharge (12) de l'au moins une première tête d'impression (09) et la surface de contact (08).
