<P>PROBLEM TO BE SOLVED: To provide a reversal system for reversing vertical swinging rotation of a jetting nozzle in a liquid jetting device. <P>SOLUTION: In the liquid jetting device rotating the jetting nozzle (rotational axis core) around the vertical axial line of a liquid supply cylinder by a relative rotation difference of the jetting nozzle with respect to a tip rotation cylinder of the liquid supply cylinder, the rotation axis 50 suspending in the axial direction in the supply cylinder 60 and rotating by receiving the driving force of a drive mechanism, is formed as a double rotation axis comprising the rotational axis core 51 and a rotation axial cylinder 52 including the rotational axis core 51, and the relative rotation difference (relative rotational angle difference) of a second transmitting means 30 for rotating the jetting nozzle 70, to a first transmitting means 20 for rotating the tip rotation cylinder 62 of the liquid supply cylinder, is switched between the positive side and negative side. Thereby, in the nozzle reversal system, when the relative rotation difference obtained by transmission from the first and second transmitting means, is in the positive side, the jetting nozzle is tilted upward, and when the relative rotation difference is in the negative side, the jetting nozzle is tilted downward. <P>COPYRIGHT: (C)2012,JPO&INPIT |
