Therefore, electrophoretic coating device 100 can, in the side of vehicle 99 and top side, make electrophoresis liquid become large to the speed of relative movement of this vehicle 99.Thus, electrophoretic coating device 100, by the right flank recycle system 113 and the left surface recycle system 114, can improve the mixing effect relative to vehicle 99.
At this, as mentioned above, the right flank recycle system 113 of present embodiment and the left surface recycle system 114 form the counter current flow of electrophoresis liquid at the side of vehicle 99 and top side, and, form the flowing of the side, side direction another side, side from vehicle 99.
Below, with reference to Fig. 2, the right flank recycle system 113 of present embodiment and the formation of the left surface recycle system 114 are described.Fig. 2 is the amplification view being carried out amplifying in the A portion in Figure 1A and illustrate.In the present embodiment, the right flank recycle system 113 and the left surface recycle system 114 are with mutually different output ejection electrophoresis liquid.
Specifically, the right flank recycle system 113 is with the output lower than the left surface recycle system 114 ejection electrophoresis liquid.Thus, the electrophoresis liquid that the side of the vehicle 99 in electrophoresis chamber 101 and top side are stirred is relative with the carriage direction of vehicle 99 and flow, and, moves from face 105 sides, left side towards right side face 104 effluents meanwhile.
In addition, the right flank recycle system 113 and the left surface recycle system 114 spray electrophoresis liquid towards vehicle 99 side with mutually different angles.Specifically, the right flank recycle system 113 extends from right side face 104 towards vehicle 99 side with the angle from 10 ° to 40 ° and arranges (the θ 1 Fig. 2.)。That is, the right flank recycle system 113 extends from right side face 104 towards vehicle 99 side with the angle less than 45 ° and arranges.Therefore, the right flank recycle system 113 facilitates the stirring of the electrophoresis liquid in electrophoresis chamber 101 towards vehicle 99 rear side.
On the other hand, the left surface recycle system 114 extends from left side face 105 towards vehicle 99 side with the angle between 50 ° to 80 ° and arranges (θ 2 Fig. 2).That is, the left surface recycle system 114 extends from left side face 105 towards vehicle 99 side with the angle larger than 45 ° and arranges.Therefore, the left surface recycle system 114 facilitates the stirring of the electrophoresis liquid in electrophoresis chamber 101 towards face 104 sides, right side.
Like this, because the right flank recycle system 113 facilitates the stirring of electrophoresis liquid to rear view of vehicle side, the left surface recycle system 114 facilitates the stirring of electrophoresis liquid to side, vehicle 99 side, therefore, facilitates the stirring of the electrophoresis liquid of the right flank side of vehicle 99 in electrophoresis chamber 101.
And, as mentioned above, because the right flank recycle system 113 is with the output lower than the left surface recycle system 114 ejection electrophoresis liquid, therefore, facilitate the stirring of the electrophoresis liquid of the right flank side of vehicle 99 in electrophoresis chamber 101.
In addition, in the present embodiment, the nozzle 113g being positioned at the side, most upstream of the right flank recycle system 113 is disposed in the position of the nozzle 114g more upstream side than the side, most upstream being positioned at the left surface recycle system 114.
On the other hand, when the nozzle 114g of the left surface recycle system 114 is disposed in the nozzle 113g upstream side than the right flank recycle system 113, consider the possibility that can exist and can not be stirred by the rear side to electrophoresis chamber 101 by the nozzle 114g electrophoresis liquid that facial 104 side sprays go out to the right.
Therefore, nozzle 113g due to the right flank recycle system 113 is disposed in the position of the nozzle 114g more upstream side than the left surface recycle system 114, therefore, it is possible to stir by the nozzle 114g of the left surface recycle system 114 electrophoresis liquid that goes out of facial 104 side sprays to the right to the rear side of electrophoresis chamber 101.
And, the nozzle 113a of the right flank recycle system 113 to nozzle 113g roughly equidistantly to arrange.In addition, the nozzle 114a to nozzle 114g of the left surface recycle system 114 is also roughly equidistantly to arrange.That is, the mode that the nozzle 113a to nozzle 113g of these right flank recycle systems 113 and nozzle 114a of the left surface recycle system 114 replaces to nozzle 114g mutually according to the carriage direction along vehicle 99 arranges.
Like this, because the nozzle 113a to nozzle 113g of the right flank the recycle system 113 and nozzle 114a of the left surface recycle system 114 alternately arranges to nozzle 114g mutually along the carriage direction of vehicle 99, therefore, by by each nozzle of the left surface recycle system 114 electrophoresis liquid of stirring of facial 104 sides to the right, can be stirred by each nozzle of the right flank recycle system 113 rear side to electrophoresis chamber 101.
Therefore, the electrophoretic coating device 100 of present embodiment maintains counter current flow in electrophoresis chamber 101, while promote the stirring of the electrophoresis liquid of the right flank side of vehicle 99.Thus, electrophoretic coating device 100 according to the present embodiment, the foreign matter of discharging from vehicle 99c is difficult to fall next vehicle 99b.
In addition, in the present embodiment, the suction recycle system 115 for sucking the electrophoresis liquid in electrophoresis chamber 101 is equipped with at the right side face 104 forming electrophoresis chamber 101.At this, as mentioned above, the electrophoretic coating device 100 of present embodiment, by the right flank recycle system 113 and the left surface recycle system 114, maintains counter current flow in electrophoresis chamber 101, while promote the stirring of the electrophoresis liquid of the right flank side of vehicle 99.
That is, because the suction recycle system 115 of present embodiment is disposed in the right flank side of vehicle 99, so easily suck electrophoresis liquid.Thereby, it is possible to suppress foreign matter being mixed into next vehicle 99 more reliably.
In addition, form suck the recycle system 115 multiple suction paths respectively with right side face 104 for axle, extend with the outside of the face 104 to the right of the angle between 10 ° to 80 ° and arrange (θ 3 as shown in Figure 2).As long as this angle is the angle of the counter current flow not hindering electrophoresis chamber 101, be not particularly limited.
Like this, the electrophoretic coating device 100 due to present embodiment maintains the counter current flow of the electrophoresis liquid in electrophoresis chamber 101, while promote the flowing of the right flank side of vehicle 99, therefore, it is possible to suppress foreign matter being mixed into next vehicle 99.
Therefore, electrophoretic coating device 100 according to the present embodiment, owing to can suppress foreign matter being mixed into next vehicle 99, sends into electrophoresis chamber 101 by multiple vehicle 99 and the productivity of electrophoresis engineering of carrying out continuously therefore, it is possible to improve.
Then, with reference to Fig. 3 A, Fig. 3 B and Fig. 4, the flowing of the electrophoresis liquid of the electrophoretic coating device 100 of present embodiment is described.Fig. 3 A is the orthographic plan of the flowing schematically showing the electrophoresis liquid in the electrophoresis chamber of the electrophoretic coating device 100 of one embodiment of the present invention from the top of electrophoretic coating device 100, and Fig. 3 B is the side elevational view of the flowing schematically showing the electrophoresis liquid in the electrophoresis chamber of the electrophoretic coating device 100 of one embodiment of the present invention from the side of electrophoretic coating device 100.In addition, Fig. 4 is the amplification view being carried out amplifying in the B portion in Fig. 3 A and illustrate.
As shown in Fig. 3 A and Fig. 3 B, to send into multiple vehicle 99 at equal intervals in the electrophoresis chamber 101 of the main composition as electrophoretic coating device 100.Now, in electrophoresis chamber 101, electrophoresis liquid sprays from the bottom surface recycle system 112, the right flank recycle system 113 and the left surface recycle system 114.Like this, because electrophoresis liquid sprays from the bottom surface recycle system 112, the right flank recycle system 113 and the left surface recycle system 114, therefore, in electrophoresis chamber 101, electrophoresis liquid is stirred.
In the present embodiment, the right flank recycle system 113 for axle, with the angle between 10 ° to 40 °, goes out electrophoresis liquid towards vehicle 99 side spray with face 104 on the right side of the electrophoresis chamber 101 being equipped with this right flank recycle system 113.
That is, due to the right flank recycle system 113 with right side face 104 for axle, go out electrophoresis liquid with at least little than 45 ° angle towards vehicle 99 side spray, therefore, the rear side towards vehicle 99 promotes the stirring of electrophoresis liquid.
On the other hand, the left surface recycle system 114, to be equipped with the left side face 105 of the electrophoresis chamber 101 of this left surface recycle system 114 for axle, goes out electrophoresis liquid towards vehicle 99 side spray between 50 ° to 80 °.
That is, due to the left surface recycle system 114 with left side face 105 for axle, go out electrophoresis liquid with at least large than 45 ° angle towards vehicle 99 side spray, therefore, the width side towards vehicle 99 promotes the stirring of electrophoresis liquid.
Now, the right flank recycle system 113 is with the spray volume fewer than the left surface recycle system 114 ejection electrophoresis liquid.Therefore, the moving phase ratio of the electrophoresis liquid flowed with the rear side towards vehicle 99 carried out by means of the right flank recycle system 113, the flowing of the electrophoresis liquid moved towards the width effluent of vehicle 99 of carrying out by means of the left surface recycle system 114 forms stronger flowing.
Thus, in electrophoresis chamber 101, the electrophoresis liquid of flowing is using the right flank side of vehicle 99 as stream, and the rear side to vehicle 99 flows.Like this, because the electrophoresis liquid of flowing is using the right flank side of vehicle 99 as stream in electrophoresis chamber 101, the rear side to vehicle 99 flows, so make the foreign matters of discharging in vehicle 99 drop to next vehicle 99.
In addition, the nozzle 113f being positioned at the side, most upstream of the right flank recycle system 113 is disposed in the nozzle 114f more upstream side than the side, most upstream being positioned at the left surface recycle system 114.And, the right flank recycle system 113 by multiple nozzle 113a to nozzle 113f along right side face 104 to arrange at equal intervals.
In addition, the left surface recycle system 114 also by multiple nozzle 114a to nozzle 114f along left side face 105 to arrange at equal intervals.That is, the nozzle 113a to nozzle 113f of these right flank recycle systems 113 and nozzle 114a of the left surface recycle system 114 alternately arranges mutually to nozzle 114f.
At this, suppose when the nozzle 114f being positioned at side, the left surface recycle system 114 most upstream be disposed in than the nozzle 113f being positioned at side, the right flank recycle system 113 most upstream more upstream side, the electrophoresis liquid flowed towards the width of vehicle 99 by nozzle 114f is difficult to flow towards the rear of vehicle 99.
On the other hand, the nozzle 114f due to the left surface recycle system 114 of present embodiment is disposed in side more further downstream than the nozzle 113f of the right flank recycle system 113, therefore, promotes the flowing to the rear side of vehicle 99 by nozzle 113f.
In addition, because the nozzle 113a to nozzle 113f of the right flank the recycle system 113 and nozzle 114a of the left surface recycle system 114 alternately arranges mutually to nozzle 114f, therefore, the nozzle 113a that flows through of the electrophoresis liquid promoted to the width side of vehicle 99 by nozzle 114a to nozzle 114f promotes to nozzle 113f to the rear side of vehicle 99.
Like this, electrophoretic coating device 100 according to the present embodiment, can maintain the flowing of the rear side to vehicle 99, namely maintain counter current flow, while electrophoresis liquid is stirred as stream in the right flank side of vehicle 99 by the left surface recycle system 114.
In addition, the suction recycle system 115 is equipped with at the right side face 104 of electrophoresis chamber 101.That is, sucking the recycle system 115 by arranging in face 104 side, right side becoming electrophoresis liquid stream, can easily the electrophoresis liquid stirred in electrophoresis chamber 101 be discharged to the outside in electrophoresis chamber 101.
As mentioned above, electrophoretic coating device 100 according to the present embodiment, by suppressing the foreign matter of discharging from vehicle 99c to the attachment of the vehicle 99a at next vehicle 99b or rear, can improve and multiple vehicle 99 be sent into electrophoresis chamber 101 continuously and the productivity of electrophoresis engineering of carrying out.
