Device for cleaning ink injection nozzles
This invention relates to a device for cleaning the ink ejection nozzles of an inkjet printer head of a mail handling machine, comprising, on the one hand, a scraping means arranged in a path of travel of the mail items opposite the ink ejection nozzles and actuated by a mail item as it advances beneath the printer head, and, on the other hand, a means for cleaning this scraping means. Advantageously, the scraping means is articulated between a position of scraping in which the scraping means is arranged in the path of travel of the mail items, and a position of rest in which the scraping means is withdrawn from this path of travel.
1. Device for cleaning ink ejection nozzles of an inkjet printer head of a mail handling machine,
wherein it comprises a scraping means arranged in a path of travel of mail items opposite the ink ejection nozzles and actuated by a mail item as it advances beneath the printer head.
2. The cleaning device of claim 1 , wherein the device further comprises a means for cleaning said scraping means.
3. The cleaning device of claim 1 , wherein said scrapping means comprises a vaned wheel.
4. The cleaning device of claim 3 , wherein a cleaning means for cleaning said vaned wheel comprises a scraper which rubs each vane of the vaned wheel.
5. The cleaning device of claim 3 , wherein said vaned wheel is motorized.
6. Device for cleaning ink ejection nozzles of an inkjet printer head of a mail handling machine, comprising:
a scraping means that is articulated between a position of scraping in which the scraping means is arranged in a path of travel of mail items, and a position of rest in which the scraping means is withdrawn from this path of travel, wherein the scraping means is opposite the ink ejection nozzles and actuated by a mail item as it advances beneath the printer head.
