Anticlogging device for ink ejection nozzle of postage meter, has suction unit arranged near brush for sucking pollutant particles torn from mail item by friction of brush on mail item, and control unit directly arranged on axis of brush

摘要

#CMT# #/CMT# The device has a rotary brush (22) arranged upstream of an ink jet printing module in a mail item transporting path (20), and driven in rotation by a rotation control unit (24). The control unit is directly arranged on a rotational axis of the brush. A suction unit (26) is arranged near the brush for sucking pollutant particles torn from a mail item by friction of the brush on the mail item. The suction unit has a fan (30) connected to an air distribution duct (32). #CMT#USE : #/CMT# Anticlogging device for avoiding clogging of an ink ejection nozzle of an ink jet printing module or print head in a postage meter (claimed). #CMT#ADVANTAGE : #/CMT# The control unit is directly arranged on the rotational axis of the brush, so that the anticlogging device is compact, thus facilitating the integration of the anticlogging device in an existing postage meter, without requiring huge modifications in the structure of the postage meter. The anticlogging device avoids clogging of the ink ejection nozzle in order to optimize the printing quality and the printing time. The anticlogging device is simple, inexpensive, and implemented during functioning of the postage meter. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic elevational view of a printing unit of a mail processing machine. 10 : Ink jet printing module 20 : Mail item transporting path 22 : Rotary brush 24 : Rotation control unit 26 : Suction unit 30 : Fan 32 : Air distribution duct.
