(EN) DEVICE FOR GUIDING MOVING LETTERS AND PARCELS

Abstract
(DE)
Die Erfindung betrifft eine Vorrichtung zum Führen bewegter Sendungen (10) an mindestens einem Tintenstrahldruckkopf (3) mit einem Transport- und Deckband (2, 4) sowie einer Führungskulisse (1) zur Verhinderung einer Tintentropfenablagerung im Bereich der Druckköpfe (3) infolge von an Kanten entstehenden Luftturbulenzen. Die Druckköpfe (3) befinden sich in Ausschnitten der Kulisse (1). Erfindungsgemäß sind mindestens in der Umgebung der Druckköpfe (3) in der Kulisse (1) in Sendungstransportrichtung verlaufende Strömungskanäle (6) vorhanden, die so tief sind, daß kein Strömungsabriß erfolgt. Zwischen den Strömungskanälen (6) befinden sich schmale Stege zum Führen der Sendungen. In Verlängerung der Stege befinden sich über den Tintenstrahldruckköpfen (3) dort schmale Führungen (7), wo die Druckdüsen (5) nicht verdeckt werden. Die nach dem jeweiligen Druckkopf (3) in Sendungstransportrichtung liegenden Stege und Führungen (7) weisen zum Verhindern des Berührens der bedruckten Sendungsteile eine gegenüber den vorhergehenden Bereichen geringere Höhe auf.
(EN)
The invention relates to a device for guiding moving letters and parcels (10) past at least one ink-jet printing head (3), with a conveyer belt and a cover belt (2, 4) and a guide frame (1) to prevent ink droplet deposition in the region of the printing heads (3) caused by air turbulence at the edges. The printing heads (3) are arranged in recesses in the frame (1). According to the invention, flow ducts (6) are provided along the direction of transport of the parcels at least in the region surrounding the printing heads (3) in the frame (1) and are deep enough to prevent stall. Narrow ridges are provided between the flow ducts (6) for guiding the parcels. Narrow guide elements (7) extend from the ridges above the ink-jet printing heads (3) where the printing nozzles (5) are exposed. The ridges and guide elements (7) downstream of a given printing head (3) in the direction of transport are lower than the preceding regions to prevent touching of the printed articles.
(FR)
L'invention concerne un dispositif permettant de guider des lettres et des colis en mouvement, qui passent devant au moins une tête d'impression à jet d'encre (3), comportant une bande transporteuse et une bande de couverture (2, 4), ainsi qu'une coulisse de guidage (1) pour éviter tout risque de dépôt de gouttes d'encre dans la zone des têtes d'impression (3), suite aux turbulences de l'air qui interviennent au niveau des arêtes. Les têtes d'impression (3) se trouvent dans des évidements de la coulisse (1). Selon l'invention, il est prévu des canaux d'écoulement à proximité des têtes d'impression (3) dans la coulisse (1), dans le sens de transport des lettres et des colis. Ces canaux d'écoulement sont d'une profondeur telle que tout risque de blocage de l'écoulement est évité. Il est prévu entre les canaux d'écoulement (6) des nervures étroites pour guider les lettres et les colis. Dans le prolongement de ces nervures, au-dessus des têtes d'impression à jet d'encre (3), se trouvent des guides (7) étroits où les buses d'impression (5) ne sont pas recouvertes. Les nervures et les guides (7) se trouvant en aval de chaque tête d'impression (3) dans le sens de transport des lettres et des colis, sont situés moins haut que les zones qui les précèdent, afin d'éviter tout contact avec les lettres et les colis imprimés.
