In the judgement of S55, CPU71 uses the output signal of the rotational position detector of X shaft encoder 69.Rotational position detector is identical with the rotational position detector 95 of Y shaft encoder 70, X axle motor 63 revolve turn around during output many signals.CPU71 does not have variation to determine the end that travelling carriage 52 has arrived movable area R1 through the output signal of rotational position detector.
(S55: not), CPU71 judges (S60) to the detection signal that has or not origin sensor 82 when not arriving the end of movable area R1.When having arrived the end of movable area R1 (S55: be), CPU71 makes X axle motor 63 carry out inversion driving.Travelling carriage 52 is towards right-hand move (S70).CPU71 transfers to S50 with processing, and repeats the action of front narration.
When the detection signal of origin sensor 82 is arranged (S60: be), CPU71 is judged to be and has accomplished the location and tenth skill.Shown in figure 13, travelling carriage 52 stops when central point C is positioned on the mobile initial point Om.(S50: not), CPU71 is judged to be and can not positions travelling carriage 52, carries out error handling processing (S65) and the end location action when in S50, having passed through the stipulated time.Error handling processing for example is that the display part 6a of indication operation board 6 shows the processing that makes mistakes and forbid beginning making action.The demonstration that makes mistakes that display part 6a stipulates.The operator will hinder the factor (the for example barrier on the mobile route of travelling carriage 52) of location to get rid of according to the demonstration that makes mistakes of display part 6a, and 6b operates to operating portion.CPU71 implements location action once more.
When travelling carriage 52 does not have the detection signal of origin sensor 82 in the process that left moves, CPU71 makes the moving direction counter-rotating of travelling carriage 52.Shown in figure 13, the travelling carriage 52 on the Y reference position is positioned at when moving initial point Om right side, and origin sensor 82 is output detection signal in the process that moves towards left.Be positioned at when moving initial point Om left side origin sensor 82 output detection signal not in the process that moves towards left at travelling carriage 52.When travelling carriage 52 does not have the detection signal of origin sensor 82 in the process that left moves, CPU71 makes the moving direction counter-rotating and the detection of wait origin sensor 82 in S70.How travelling carriage 52 can irrespectively be positioned to move initial point Om with the initial position of left and right directions.
In addition; In this embodiment; Because the initial point input position beyond in the Y reference position can not detect the X reference position, so, can not detect the X reference position even think the initial point input position beyond the Y reference position by mistake to be the Y reference position because of barrier.Therefore, in this embodiment, can the position beyond the predefined mobile initial point Om be made as mobile initial point.
Below to partial alteration the variation of embodiment of top explanation describe.
(1) shown in figure 14, the Y axis datum position also can be that the initial point signal detector 96 of Y shaft encoder 70 detects the position of initial point signal for the first time.The Y axis datum position also can be that initial point signal detector 96 detects the position of initial point signal for the third time.Moving initial point Om also can be the excentral position of movable area R0, R1.
The input operation of (2) moving the operating portion 6b that initial point Om also can be through operation board 6 is set.The operator sets with respect to the directions X of the center of movable area R0, R1, side-play amount on the Y direction through input and moves initial point Om.
(3) shown in figure 16, Y shaft encoder 70 also can comprise the check-out console 93A of simple circular plate type.Check-out console 93A comprises the origin position surveyed area in the outside of rotation surveyed area.Identical with check-out console 93, the rotation surveyed area is the zone that many slit 93d are set up in parallel on complete cycle with the interval of equalization.The origin position surveyed area is the zone that many slit 93e are set up in parallel on half cycle (180 °) with the interval of equalization.Initial point signal detector (not shown) comprises illuminating part, light accepting part respectively in the face side and the rear side of origin position surveyed area.The initial point signal detector is exported detection signal many times during the half-turn (180 °) corresponding with the scope that forms slit 93e, output detection signal not during the remaining half-turn corresponding with the scope that does not form slit 93e (180 °).The scope that does not form slit 93e is equivalent to shielding portion, and the scope that forms slit 93e is equivalent to local shielding portion.The initial point signal detector switches to output state in initial point input position when check-out console 93A is just changeing, when check-out console 93A reverses, switch to non-output state in initial point input position.CPU71 can change the origin position that detects Y axle motor 64 according to the output of initial point signal detector.
