PRINTING APPARATUS

摘要

[Problems to be Solved];Provision of a printing apparatus which is capable of printing a pattern and/or a character on a curved printed surface, such as an airframe surface of a passenger aircraft, in a very short time.;[Means for Solving the Problems];A head array 3 having therein a plurality of inkjet nozzles 16 for ejecting ink toward a remote position by supplying pressurized air to every ink tanks 6 filled with the ink, respectively, is mounted on a linear array 4 so as to be able to perform linear reciprocation, the linear rail being held by an robot arm 5a of a multi-articulated robot 5, and a position at which the robot arm 5a is to be disposed is controlled on the basis of position information, while controlling of driving of predetermined nozzles 16 in the head array 3 is performed in association with the position information.

主权项

1. A printing apparatus for printing a pattern and/or a character by performing ejection of a predetermined ink to a predetermined targeted position of a curved printed surface, comprising:
a head array provided therein a plurality of inkjet nozzles configured to eject an ink toward a remote position by supplying pressurized air to an ink tank filled with the ink to thereby apply thereto high-pressure air; a linear rail configured to allow the head array to make linear reciprocation therealong; a multi-articulated robot provided with a robot arm arranged for appropriately moving the linear rail to a predetermined position and for holding the linear rail at the predetermined position; a robot arm controller configured to control driving of the robot arm on the basis of position information; and a controller configured to supply the position information to the robot arm controller, and to perform driving control of the predetermined inkjet nozzle of the head array in association with the position information.
