Detailed description of the invention
Below, based on preferred embodiment, with reference to accompanying drawing, the present invention is described.
An example (the first embodiment) of the nozzle head that painting device of the present invention uses is represented in Figure 1A and Figure 1B.Figure 1A is the sectional view parallel with application face, and Figure 1B is the sectional view vertical with application face.In addition, represent the structure from three branch flow passage to nozzle in Figure 1B, the structure of the coating introduction part should intersected in the cross section identical with Figure 1B and a branch flow passage omits diagram.
Nozzle head 10 shown in Figure 1A and Figure 1B has: respectively install nozzle 11,12,13,14 multiple ejiction openings 27,27, The coating introduction part 20 fewer than the quantity of multiple ejiction opening 27,27 ...; With from coating introduction part 20 to multiple ejiction opening 27,27 ... extension the painting flow path 16 of mode branch.
Coating introduction part 20 is the single coating introduction parts be connected with the painting flow path of coating material supply system.In figure ia, coating introduction part 20 is configured with in the substantial middle of nozzle head 10.In coating material supply system, never illustrated paint can is to the painting flow path conveying coating of each nozzle.In nozzle body 15, formation extends from coating introduction part 20 and is branched off into the multiple ejiction openings 27 corresponding with each nozzle, the painting flow path 16 of 27 ....
Nozzle 11,12,13,14 is arow configuration on nozzle head 10.In figure ia, see with the plane parallel with application face, from one end 18 (first end) of nozzle body 15 to the other end 19 (the second end), be configured with nozzle from coating introduction part 20 all directions in the lateral direction.The number being configured at the nozzle of right direction from coating introduction part 20 is identical with the number of the nozzle being configured at left direction from coating introduction part 20.These nozzles 11,12,13,14 as shown in Figure 1B, are formed highlightedly from the one side (being configured at the face in the application face of coated object, nozzle forming surface 17 substantially in parallel) of nozzle head 10 to the emission direction of coating.Nozzle forming surface 17 arranges ejiction opening 27.These nozzles 11,12,13,14 as shown in Figure 1B, configure symmetrically relative to the middle position C of row.In the present embodiment, be provided with 8 nozzles row, be configured with 4 nozzles 11,12,13,14 in the both sides of middle position C respectively.In Figure 1A and Figure 1B, from the position near middle position C to the position away from middle position C, to multiple nozzle successively annotated mark 11,12,13,14, and the nozzle difference that will adjoin each other.Nozzle near middle position C represents to mark 11, nozzle farthest away from middle position C represents to mark 14, and the nozzle between nozzle 11 and nozzle 14 represents to mark 12,13 successively on the direction (left and right directions) from nozzle 11 towards nozzle 14.As shown in Figure 1B, the painting flow path in each nozzle is formed on central shaft, offers coating jet in the front end of nozzle.
As shown in Figure 1A, distance between centers L1, L2, L3, L4 of nozzle 11,12,13,14 of adjoining along the direction of row distance between centers met near the nozzle of middle position C be away from the distance between centers of the nozzle of middle position more than relation.The distance between centers of nozzle 11,11 is set to L1, the distance between centers of nozzle 11,12 is set to L2, the distance between centers of nozzle 12,13 is set to L3, the distance between centers of nozzle 13,14 is set to L4, meets the relation of L1 >=L2 >=L3 >=L4.In the present embodiment, the distance between centers particularly met near the nozzle of middle position C compares away from the large relation of the distance between centers of the nozzle of middle position C, and meets the relation of L1 > L2 > L3 > L4.
In addition, as shown in Figure 1B, with the nozzle near middle position C with the mode of more spray volume ejection coating (with the nozzle away from middle position C in the mode of less spray volume ejection coating), set spray volume Q1, Q2, Q3, Q4 of the coating sprayed from each nozzle 11,12,13,14.Namely, the spray volume of nozzle 11 is set to Q1, the spray volume of nozzle 12 is set to Q2, the spray volume of nozzle 13 is set to Q3, the spray volume of nozzle 14 is set to Q4, meets the relation of Q1 > Q2 > Q3 > Q4.According to the size of spray volume Q1, Q2, Q3, Q4, as shown in Figure 1A, the area of the application pattern 31,32,33,34 formed by each nozzle 11,12,13,14 is also different.That is, the application pattern that the coating sprayed by the nozzle more from spray volume is formed broadens, and the application pattern that the coating sprayed by the nozzle less from spray volume is formed narrows.
Like this, near the nozzle of middle position, set the spray volume of coating from nozzle ejection, thus, even if the mode overlapped each other with the circumference of application pattern carries out two road coatings, the thickness of film also can not excessively increase manyly.Therefore, even handwork, uniform two road coatings also easily can be formed.Due to adjacent nozzle application pattern 31,32,33,34 overlapped, so also not easily produce coating residue.
Each nozzle 11,12,13,14 preferably has the two-fluid spray nozzle being coated with flow path and atomizing air stream.The nozzle body 15 of nozzle head 10 connects the atomizing air feed system (not shown) of the coating material supply system to the painting flow path supply coating of each nozzle and the atomizing air stream supply atomizing air to each nozzle.The never illustrated compressor of atomizing air feed system is to the atomizing air stream supply atomizing air (compressed air of atomization) of each nozzle.In addition, in nozzle body 15 formed connect described atomizing air feed system atomizing air stream single atomizing air supply port (not shown) and from this atomizing air supply port to the atomizing air stream (not shown) of each nozzle branch.In Figure 1A and Figure 1B, only figure is shown with coating stream, but atomizing air stream (not shown) is concentrically located at around painting flow path in nozzle 11,12,13,14.The atomizing air jet of ring-type is offered in the front end of atomizing air stream.
Supply coating from painting flow path 16 to each nozzle 11,12,13,14 and from atomizing air stream supply atomizing air, thus, the coating sprayed undertaken being atomized by the atomizing air sprayed from atomizing air jet and spray to application face from coating jet.On the injection direction of each nozzle, formed such as cone shape application pattern by the coating particle of spraying, blow the application face of being attached to simultaneously.
In the present embodiment, the quantity of multiple ejiction opening 27,27 ... is the power times of two relative to the quantity of coating introduction part 20, is specifically 8 times.A stream, from coating introduction part 20 towards multiple ejiction opening 27,27 ..., namely from coating introduction part 20 towards the path of arbitrary ejiction opening, is branched off into two by the painting flow path 16 in nozzle body 15.In addition, the quantity of the branch part in arbitrary path is mutually identical.
As shown in Figure 1A, be coated with flow path 16 and there are a pair one time branch flow passage 21,21 and a pair two times branch flow passage 22,22 and a pair three times branch flow passage 231,232,233,234.
At this, a pair one time branch flow passage 21,21 is the first branch point 24 branch from the downstream being positioned at single coating introduction part 20 and mutually with the branch flow passage that identical flow path length extends.
A pair two times branch flow passage 22,22 are the second branch point 25 branch from the downstream being positioned at each branch flow passage 21 and mutually with the branch flow passage that identical flow path length extends.
A pair three times branch flow passage 231,232,233,234 are branch flow passage of the 3rd branch point 26 branch from the downstream being positioned at each secondary branch flow passage 22.
The downstream of three branch flow passage 231,232,233,234 is install the ejiction opening 27 of nozzle 11,12,13,14 respectively.
In the present embodiment, as shown in Figure 1A, be coated with flow path from the first branch point 24 branch and form a branch flow passage 21,21 to the left and right of coating introduction part 20 of central authorities being positioned at nozzle head 10, branch flow passage 21,21 is generally perpendicularly after slight curvature, and one time branch flow passage 21,21 arrives the second branch point 25 respectively.Be coated with flow path from each second branch point 25 branch and form secondary branch flow passage 22,22 to the left and right, secondary branch flow passage 22,22 is generally perpendicularly after slight curvature, and secondary branch flow passage 22,22 arrives the 3rd branch point 26 respectively.And then, be coated with flow path from each 3rd branch point 26 branch and form three branch flow passage 231,232,233,234 to the left and right.In three branch flow passage 231,232,233,234, three times branch flow passage 231,232 is configured between the first branch point 24 and the second branch point 25 in the lateral direction, three times branch flow passage 233 is configured between the second branch point 25 and one end 18 of nozzle body 15 (left direction), and three times branch flow passage 234 is configured between the second branch point 25 and the other end 19 of nozzle body 15 (right direction).At this, the left and right of Figure 1A refers to the direction of the row configuring multiple nozzle.Three branch flow passage 231,232,233,234 as shown in Figure 1B, after nozzle 11,12,13,14 slight curvature, arrive ejiction opening 27.
From the first branch point 24 to the three branch point 26, formed in the same face parallel with nozzle forming surface 17 and be coated with flow path.In the half-way of three branch flow passage 231,232,233,234, as shown in Figure 1B, the painting flow path vertical with nozzle forming surface 17 is formed.In addition, in the present embodiment, the painting flow path formed in the same face shown in Figure 1A is made up of the stream parallel or vertical with the column direction of nozzle, but the present invention is not limited thereto, and also can arrange the painting flow path extended obliquely relative to the direction of row.
In a branch flow passage 21,21, not only flow path length is mutually equal, and flowing path section area is also equal.In addition, in secondary branch flow passage 22,22, not only flow path length is mutually equal, and flowing path section area is also equal.The flowing path section area of secondary branch flow passage 22 is the half of the flowing path section area of a branch flow passage 21.The number of secondary branch flow passage 22 is two times of a branch flow passage 21, and therefore, the total of the flowing path section area of each secondary branch flow passage 22 is equal with the total of the flowing path section area of each branch flow passage 21.
Like this, except the first branch point 24 of branch initial after coating introduction part 20 with beyond the final branch point (the 3rd branch point 26) of multiple ejiction opening 27, the front last branch in 27 ..., be arranged in each branch point (the second branch point 25) of midway, the total of the area of section of the stream (secondary branch flow passage 22) after branch is equal with point area of section of the stream (branch flow passage 21) of supporting the front, thus, coating balance between supply and demand when carrying out two branches is good, is easy to distribute equably.
In addition, in the present embodiment, area of section and the length of the painting flow path (three branch flow passage 231,232,233,234) from final branch point (the 3rd branch point 26) to ejiction opening 27 are mutually different.Thus, spray volume Q1, Q2, Q3, Q4 of the coating sprayed from each nozzle 11,12,13,14 is controlled.Such as, the area of section supplying three branch flow passage 231,232 of coating to two nozzles 11,12 near middle position C is larger than the area of section supplying three branch flow passage 233,234 of coating to two nozzles 13,14 away from middle position C.Thus, the control making spray volume Q1, Q2 of nozzle 11,12 more than spray volume Q3, Q4 of nozzle 13,14 becomes easy.
In addition, for the length of two three branch flow passage from the 3rd identical branch point 26 2 branch, three branch flow passage 231 supplying coating to the nozzle 11 near middle position C are shorter than three branch flow passage 232 supplying coating to the nozzle 12 away from middle position C.Supply the relation of three branch flow passage 233,234 of coating to nozzle 13,14 too, three times branch flow passage 233 to three branch flow passage 234 are shorter.Thus, the spray volume Q1 of nozzle 11 is more than the spray volume Q2 of nozzle 12 and spray volume Q3 that is nozzle 13 is more than the spray volume Q4 of nozzle 14 control becomes easy.
Spray volume Q1, Q2, Q3, Q4 of coating pass through area of section and the cut to lengthen of three branch flow passage 231,232,233,234, and therefore, bore D1, D2, D3, the D4 of the painting flow path in each nozzle 11,12,13,14 also can be mutually equal.In this case, the nozzle of same size can be installed as each nozzle 11,12,13,14, therefore, it is possible to suppress cost.
An example (the second embodiment) of the nozzle head that painting device of the present invention uses is represented in Fig. 2 A and Fig. 2 B.Fig. 2 A is the sectional view parallel with application face, and Fig. 2 B is the sectional view vertical with application face.In fig. 2b, the same with Figure 1B, will structure local omit and diagram from three branch flow passage to the structure of nozzle.The formation of the second embodiment can be set to roughly the same with the first embodiment, and therefore, the repetitive description thereof will be omitted, below, difference is described.
As shown in Figure 2 B, in the present embodiment, bore D1, D2, D3, the D4 of the painting flow path in each nozzle 11,12,13,14 are mutually different.Specifically, become large mode (mode diminished with the bore of the nozzle away from middle position C) with the bore of the nozzle near middle position C, the size of setting bore D1, D2, D3, D4.Namely, the painting flow path bore of nozzle 11 is set to D1, the painting flow path bore of nozzle 12 is set to D2, the painting flow path bore of nozzle 13 is set to D3, the painting flow path bore of nozzle 14 is set to D4, meets the relation of D1 > D2 > D3 > D4.Thus, about the relation of spray volume, also meet the relation of Q1 > Q2 > Q3 > Q4.The area of application pattern 31,32,33,34 is the same with the first embodiment, according to the size of spray volume Q1, Q2, Q3, Q4, the application pattern that the coating sprayed by the nozzle more from spray volume is formed broadens, and the application pattern that the coating sprayed by the nozzle less from spray volume is formed narrows.
Like this, the design according to nozzle 11,12,13,14 makes spray volume change, and therefore, the painting flow path 16 in nozzle body 15 can with until the mode that ejiction opening 27 distributes coating be equably formed.On nozzle head 100, nozzle 11,12,13,14 equally spaced configures.That is, as shown in Figure 2 A, distance between centers L1, L2, L3, L4 of the nozzle 11,12,13,14 that the direction along row adjoins are mutually equal, and meet the relation of L1=L2=L3=L4.
In addition, not only from the first branch point 24 to the three branch point 26, the area of section of stream and length impartial in the same manner as the first embodiment, and also mutually equally to form from the 3rd branch point 26 as final branch point to the area of section of the painting flow path (three branch flow passage 23) of ejiction opening 27 and length.Namely, in the second branch point 25, the total of the area of section of the stream (secondary branch flow passage 22) not only after branch is equal with point area of section of the stream (branch flow passage 21) of supporting the front, and in the 3rd branch point 26, the total of the area of section of the stream (three branch flow passage 23) after branch is also equal with point area of section of the stream (secondary branch flow passage 22) of supporting the front.Thus, from coating introduction part 20 in multiple streams of ejiction opening 27, coating balance between supply and demand when stream is branched off into two is good, is easily allocated in equably by the coating flowed in stream and is branched off in multiple streams.In this case, the difference of the bore of nozzle becomes the main cause of spray volume change, and therefore, the control of spray volume is easy.
Above, based on preferred embodiment describing the present invention, but the invention is not restricted to above-mentioned embodiment, various change can be carried out without departing from the scope of spirit of the present invention.
Painting device preferably possesses the clean unit utilizing painting flow path in air or diluent flush two-fluid spray nozzle and atomizing air stream.By flowing through diluent in painting flow path, coating can be dissolved and remove.In addition, by flowing through air in painting flow path, can by dry for painting flow path.Atomizing air stream flows only through air usually, therefore, do not need to clean, but coating also sometimes adheres to from the front end of nozzle, invades.Therefore, preferably by flowing through diluent and dissolution of coatings in atomizing air stream, or dispelled by the pressure of air, thus will the coating removing of attachment.Diluent according to compositions such as the resin comprised in coating or pigment, can suitably select the organic solvent of low polarity or high polarity.
With regard to painting device, carry out operation because operator is hand-held, therefore, preferably possess the hand lance being provided with nozzle head.Preferred hand lance is arranged the operating portion being used for the flow adjusting coating and atomizing air on hand.Clean unit not need when application to be arranged on hand lance, therefore, preferably having can by the coupling of clean unit from hand lance dismounting by singly-key type.
The direction of nozzle head preferably can freely be changed (rotation).Thereby, it is possible to easily change the direction of pattern (application pattern).Horizontal plane, vertical plane, inclined plane can be enumerated in the direction in application face.Direction from from nozzle to the attached coating of application top blast be laterally, upwards, downwards, any direction such as incline direction.When possessing hand lance, preferably rotating mechanism being set between gripping section and nozzle head, even if operator does not change the direction of the gripping section of hand, also changing the direction of (rotation) nozzle head.
Preferably possess in the both sides of nozzle head for application distance is set to certain rotation pad.Rotating the outward appearance that pad has such as wheel shape, by rotating on application face, nozzle head can be made to move in parallel.
In the nozzle head of illustrated example, multiple nozzle shape is configured in a row, but also can be configured to more than two row.
Nozzle forming surface is set to plane in illustrated example, but also can have concavo-convex or rise and fall, curved surface.The ejiction opening of nozzle is installed be formed in illustrated example in nozzle forming surface, but also can be set to ejiction opening is set at the end of the recess caved in from nozzle forming surface, and a part for nozzle is imbedded the formation of this recess.
On nozzle head, the number being configured to the nozzle of row both can be even number, also can be odd number.If at the nozzle of a row configuration more than 4, then can the present invention be applied.
Such as, when 4 nozzles N1, N2, N3, N4 arranging one configure successively, N2, N3 are for leaning on ectocentral nozzle, and N1, N4 are the nozzle away from central authorities.In this case, the distance between centers between N2, N3 is more than the distance between centers between N1, N2 and between N3, N4, and the spray volume of N2, N3 sets manyly than the spray volume of N1, N4.
In addition, when 5 nozzles N1, N2, N3, N4, N5 arranging one configure successively, N3 is the nozzle near central authorities, and N1, N5 are the nozzle farthest away from central authorities.In this case, the distance between centers between N2, N3 and between N3, N4 is more than the distance between centers between N1, N2 and between N4, N5, and the spray volume of N3 is more than the spray volume of N2, N4, and the spray volume of N2, N4 sets more than the spray volume of N1, N5.
The quantity being located at the coating introduction part of nozzle head both can be one, also can be two, more than three or three.Be the power of two doubly (4 times, 8 times, 16 times etc.) by the quantity of multiple ejiction opening relative to the number of coating introduction part, from coating introduction part towards in the path of arbitrary ejiction opening of multiple ejiction opening, a stream be branched off into two.In addition, the quantity of the branch part in arbitrary path is mutually identical.
