Be used to form the application system of protective layer

Technical field

The present invention relates to a kind of application system; this application system forms protective layer after spraying paint on the zone of spraying paint that material mainly is applied to the vehicle outer surface; be particularly related to a kind of roller that uses and apply the application system that the liquid protective layer forms material, this roller contacts with described intimate.

Background technology

Vehicle (for example car) is stored in the parking before consigning to client usually after manufacturing, and carries by analogs such as train and steamers.During this period of time, vehicle is exposed to dust, metal dust, salt, oil, the acid neutralization directly is exposed in the sunlight, and if their store or time of carrying longer, the outermost quality possible deviation in the multilayer of the vehicle lacquer then.In order to prevent this situation, known a kind of method (for example, Japanese Laid-Open Patent Publication No.2001-89697) that before transporting vehicle, on the zone of spraying paint, forms peelable protective layer.Form material (be also referred to as and peel off coating) and make the material drying that is applied form peelable protective layer, zone by applying liquid cover layer or protective layer thereby protection is sprayed paint.And this peelable protective layer can be easy to be stripped from when removing, and can not come off naturally in the normal storage process.

Apply the processing procedure that protective layer forms material before with peelable protective layer drying and carry out like this, be about to protective layer and form material adhesion on roller, and roller is rolled along described surface, form material thereby apply protective layer.

In order to make this operation automation and to make that to apply quality even; a kind of method has been proposed; wherein, dry after pouring into to car body protective layer being formed material, so that protective layer forms material diffusion (for example seeing Japanese publication document No.08-173882).By using this method, a lot of coating processing operations are automatically, thereby have reduced staff's burden, and have improved cycle time, and this is preferred.

But in using Japanese Laid-Open Patent Publication No.08-173882 during disclosed method, it is evenly inevitable that protective layer forms the diffusion of material, and in order to prevent that protective layer from forming material generation splash loss, therefore do not apply this material on the roof edge.

And recent car body becomes and becomes increasingly complex, and has recessed and raised zones, and these are recessed and raised zones is very complicated because of having thin portion curve.It is very difficult using air nozzle to make protective layer formation material diffuse on these recessed zones and the curved surface.And for the very important zone of coating quality, protective layer forms material require and applies thickly especially, but is difficult to the thickness of control coating when utilizing air nozzle to make protective layer form the material diffusion.

Therefore, utilizing air nozzle to make after protective layer forms the material diffusion, needing a plurality of operating personnel to come to be applied on the roof edge and in the zone similarities such as thin portion zone in recessed zone and to finish this layer by protective layer being formed material with roller.Therefore, the processing procedure that applies that protective layer forms material partly depends on operating personnel, therefore becomes operating personnel's burden, and makes that coating quality may be according to operators'skills and difference.

In order to reduce the required workload of operating personnel and to make operation quality more even, after deliberation the utilization of industry mechanical arm, this industry mechanical arm uses the roller that is used by operating personnel usually.At this moment, preferably use pump to come automatically to supply with protective layer and form material to roller.

But, the protective layer that supplies to roller inside forms the inevitable surface that infiltrate into roller equably of material, and material is difficult to move to the end of roller, and becomes dry sometimes.Therefore, the protective layer that is applied on the vehicle forms material and inhomogeneous, and also inconsistent sometimes.

On the other hand, the application's applicant considered in the past to improve and applied the uniformity of quality and the needs of working automation, proposed application system and the applying method put down in writing as among the Japanese patent application No.2002-381880.In Japanese patent application No.2002-381880; be used for that protective layer is formed material and be applied to processing procedure on the vehicle outer surface by using further automation by the roller of Robot actions; this can improve the uniformity that applies quality, enhances productivity simultaneously and simplification work.

92a and 94a divides between the 76a two lower extension.

Rotary actuator 96 is arranged on the top of thrust rotating member 74, and stretch out from the bottom of connecting elements 70 be arranged in the recessed regional 96a of the upper surface of rotary actuator 96 than small embossment 98.This width than small embossment 98 is slightly less than the width of recessed regional 96a, and in this interstice coverage, thrust rotating member 74 can rotate freely along thrust direction.Thrust direction described here is the direction with the axis normal of roller 48, is to utilize the direction of rotation of the axis C of the 3rd arm 46 as central axis.The bolt 100 that connecting elements 70 is connected on the 3rd arm 46 also can be used as than small embossment 98.

Two anchor clamps 102 are set to upper-part relative in connector 88 and lower member with 104, and because aluminum pipe 106 is supported by anchor clamps 102 and 104, so support 86 is connected with pivot member 84.Cannelure 106a is arranged on the surface of aluminum pipe 106.

As shown in Figure 4 and Figure 5, support 86 is equipped with rack body 86e, and the end of this rack body 86e is connected on the fixed support 86a fixing by bolt 86b, but and the other end pass shaft component 86d with free rotation mode and be connected on the travel(l)ing rest 86c.Connector 110b is fixed on the fixed support 86a by nut 110a, and conduit 22 is connected with opening at the end place of connector 110b.

Rack body 86e is longer slightly than roller 48, and is parallel flat element, and is arranged on fixed support 86a on the two ends and travel(l)ing rest 86c with can be by hollow pipe 112 and free rotation mode backing roll 48.

On the other hand, the first end 112a of pipe 112 is connected with the opening at connector 110b other end place.Protective layer forms material by managing 112 and supply to roller 48 from conduit 22.Managing 112 backing rolls 48 makes roller 48 to rotate freely.Conical tank (not shown) that the first end 112a has a plurality of (for example two), and manage 112 by with the analog (not shown)s such as stud bolt that enter from connector 110b side the groove, be securely fixed on the connector 110b in the mode that engages.The second end 112b sealing of pipe 112.

Pipe 112 has a plurality of holes, and these hole shapes become the protective layer that is used for to roller 48 supplies have been supplied with and form material.Hole 114 can form nozzle form.In addition, preferably manage 112 and form, and for example be more preferably by the SUS304 material and form (steel pipe that is categorized as austenitic type according to the JIS of Japanese Industrial Standards) by stainless steel.

The end side of travel(l)ing rest 86c is formed with cannelure 86f.Travel(l)ing rest 86c can rotate by spring (elastomeric material) application of force (reference direction of arrow A among Fig. 5).In other words, travel(l)ing rest 86c utilizes the elastic force of spring 116 and moves to the holding position, and this makes the second end 112b of pipe 112 be connected with cannelure 86f.In addition, when installation and removal during roller 48, when make travel(l)ing rest 86c when arrow A 1 direction is moved specified angle with hand, the elastic force of spring 116 will act in opposite direction.Like this, travel(l)ing rest 86c will move to disengaged position, shown in the double dot dash line among Fig. 5.

Like this, travel(l)ing rest 86c can be at an easy rate effect by spring 116 move to bearing position or disengaged position, and when at bearing position, pipe 112 can be supported reliably.And, when being in a disengaged position, comparing with bearing position, travel(l)ing rest 86c is arranged on the position that can fully rotate, and not unexpected the pivot, therefore mounts and dismounts roller 48 and is easy to.

Preferably, the anglec of rotation of travel(l)ing rest 86c is set to greater than 90 degree, more preferably is set between 100 degree and 180 degree.

As Fig. 5 and shown in Figure 7, roller 48 forms by absorbing the material that forms material with the storage protection layer, and is equipped with: hollow applicator 48a, and this hollow applicator 48a applies protective layer formation material by closely contact with the surface of vehicle 14; And end cap 50, this end cap 50 makes the opening 48b liquid in the two ends of applicator 48a seal by O shape ring 120.Center at end cap 50 is porose, and this hole is not shown in the drawings, and because pipe 112 inserts whole roller 48 can free rotation mode being supported by these holes.To manage 112 and the cooperation level in hole regulate, remain on applicator 48a inside protective layer is formed material.

Pipe 112 is formed with a plurality of hole 114a to 114e, so that already provided protective layer is formed material feed roller 48.Hole 114a to 114e equidistantly makes along the direction of arrow B 1 from first end 112a to the second end 112b.Hole 114e near the second end 112b forms diameter greater than the hole 114a near the first end 112a.More particularly, the diameter D1 to D5 of hole 114a to 114e for example is arranged to concern D1=D2＜D3=D4＜D5.

In addition, for roller 48, the first end 112a of pipe 112 is connected with conduit 22, and forms material by being expelled in the roller 48 at the hole 114a to 114e that manages in 112 by the protective layer that conduit 22 is supplied with.In this case, because the diameter of hole 114a to 114e is set to for example D1=D2＜D3=D4＜D5, so protective layer formation material can in axial direction supply on the whole length of roller 48 equably.

As shown in Figure 8; when the diameter D1 to D5 of hole 114a to 114e equated, flowing through the amount that protective layer near the hole 114a of the first end 112a (this first end 112a is connected with conduit 22) forms material will be greater than the amount of the protective layer formation material of the hole 114e that flows through the close second end 112b.Therefore; have than near the bigger diameter of the diameter D1 of the hole 114a of the first end 112a time when the diameter D5 near the hole 114e of the second end 112b forms, the protective layer of approximate even amount forms material will flow out (with reference to the solid line among the figure 8) from

hole

114a, 114e.

Therefore, the approximate uniform protection layer of the amount of per unit area forms material and can flow out from hole 114a to 114e along pipe 112 axial directions, and protective layer formation material can evenly be supplied with along the whole length of roller 48 in the axial direction.Therefore, can utilize simple structure to obtain to apply uniformly quality and high-precision coating operation.

In addition, by the roller 48 and the support 86 of such formation, roller 48 can mount and dismount at an easy rate, and can improve the operational capacity of roller 48.Therefore, even when needs frequent maintenance (for example cleaning or change roller 48), this attended operation also can be finished effectively.

In addition, by such formation roller 48, form material by applicator 48a reception and storage by managing 112 protective layers of carrying, and be applied to reliably on the surface of vehicle 14 by this applicator 48a.

And, because at applicator 48a with manage in the space between 112 and do not have anything, so roller 48 will be lighter.Also have, when preparing to apply operation, the protective layer of specified quantitative forms material can place this space in advance, forms material so that prevent to supply with deficiently protective layer in applying operating process.

Should be noted that in hybrid system 150 compressor 152, air reservoir 154, watering 24 and pump 32 are shared for

manipulator

16a, 16b, 16c, and miscellaneous equipment provides respectively for each

manipulator

16a, 16b, 16c.

To introduce below and utilize the application system that is used to form protective layer that constitutes like this to apply the operation that protective layer forms material to vehicle.

Instruct the motion of each

manipulator

16a, 16b, 16c at first, in

advance.Manipulator

16a, 16b, 16c distribute to hood 14a, roof middle part 14b and the roof rear end 14c of vehicle 14 respectively; and applied protective layer by instruction to the appointed area and form material, and the instruction data record that is used for instructing and be held in place in the memory of controller 18 (with reference to figure 1).Should be noted that manipulator 16c distributes to tailstock trunk area if vehicle 14 is cars.

In other words, as shown in figure 10, instruct like this, promptly the 3rd arm 46 of manipulator 16a remains on from the enough distances in vehicle 14 surfaces, and the inclination angle of pivot member 84 is a fixed angles theta.The inclination angle of pivot member 84 remains angle θ substantially, but can ignore more shallow regional 200 and shorter raised zones 202, and the angle of pivot member 84 changes a little.By ignoring more shallow regional 200 and shorter raised zones 202 like this, the action instruction of manipulator 16a becomes easy.

Then, as shown in figure 10, when manipulator 16a is forming protective layer when moving right when material imposes on vehicle 14, air is fed into right cylinder 80, thereby produces relatively low power Fa along the direction of bar 80a withdrawal.And air is fed into left hand cylinder 78, so bar 78a will stretch out.Therefore, right side pin pressing member 94 push surperficial 94a with more weak defeating on the right lateral surface of pin 90 relatively, and the surperficial 92a that pushes of left side pin pressing member 92 separates with pin 90.Therefore, pivot member 84 and roller 48 receive around pivot 82 power in the counterclockwise direction, and roller 48 is pressed to vehicle 14 surfaces with suitable pressure.

Power Fa will and apply the zone according to movement technique and regulate.By carrying out above-mentioned adjusting at an easy rate by the pressure regulatory function of controller 18 operate regulator 176 or by using analogs such as specifying rotating disk.

On the other hand, as shown in Figure 11, during to left movement, air is fed into left hand cylinder 78, thereby produces relatively low power Fa along the direction of bar 78a withdrawal when manipulator 16a is forming material with protective layer and imposes on vehicle 14.And air is fed into right cylinder 80, so bar 80a will stretch out.Therefore, left side pin pressing member 92 push surperficial 92a with more weak defeating on the left-hand face of pin 90 relatively, and the surperficial 94a that pushes of right side pin pressing member 94 separates with pin 90.Therefore, pivot member 84 and roller 48 receive around pivot 82 power along clockwise direction, and roller 48 is pressed to vehicle 14 surfaces with suitable pressure.

Like this, by controlling airflow direction and the air pressure that is fed into

cylinder

78 and 80, can correctly roller 48 be pressed to vehicle 14 surfaces according to the manipulator 16a direction of motion.In other words, since the weight that effectively utilizes roller 48, can't help the required power that this weight provides as pressure and can compensate by the pressure of cylinder 78 and cylinder 80.

Therefore, when through recessed zone 200 or raised zones 202, roller 48 will can not rotate freely, and can not jump.And protective layer forms material and will be easy to ooze out from roller 48.At this moment, roller 48 can rotate around pivot 82, and can keep reliably closely contacting with raised zones 202 with recessed regional 200, forms material thereby can apply protective layer.In other words, when recessed zone 200 of roller 48 processes and raised zones 202, the height of bar 78a or recessed regional 200 the degree of depth of bar 80a basis or raised zones 202 stretches out or

withdraws.Cylinder

78 and 80 uses highly compressible air as drive medium, therefore can carry out compliant motion, and is easy to absorb the external pressure variation.In other words, first cylinder 78 and second cylinder 80 have the effect of pushing and buffering effect.

The pin pressing member 92 that is connected with the bar 78a of cylinder 78 is exerted pressure on pivot member 84 in opposite direction with the pin pressing member 94 that is connected with the bar 80a of cylinder 80, so, can carry out correct motion no matter pivot member 84 is along clockwise direction or angled in the counterclockwise direction.Therefore, can when moving to the left or to the right, apply protective layer and form material.

Then, having the vehicle 14 that the protective layer that is applied by

manipulator

16a, 16b, 16c forms material is transferred to carry out next processing by pipeline 12.And

manipulator

16a, 16b, 16c remain on not the spare space of interfering with vehicle 14, and wait up to introducing next vehicle 14 always.At this moment, starter gate valve 164 cuts out, and stops to supply with protective layer formation material.

The protective layer that applied forms material can air dry, perhaps dry by forced ventilation, thereby forms the regional peelable protective layer that sprays paint of protection vehicle.

As mentioned above, by the application system 10 of present embodiment, can improve the manipulation of roller 48 by the roller 48 of roller mechanism 34 supportings by installation and removal.Therefore, can carry out the maintenance of roller 48 effectively.And roller 48 is supported and supplies with matcoveredn formation material by managing 112, so roller mechanism 34 is simple in structure.And, although the structure of roller mechanism 34 is simplified, still can apply protective layer reliably and form material.

Introduce first to the 7th optional embodiment of roller mechanism 34 below with reference to Figure 12 to Figure 30.Should be known in the following description, will represent with identical Reference numeral, and will omit explanation them with element identical in the aforementioned roller mechanism 34 or among other optional embodiment.

As shown in figure 12, similar according to the roller mechanism 34a and the roller mechanism 34 of the application system that is used to form protective layer of the first optional embodiment, wherein manage 112 (with reference to figure 7) and replace by pipe 182.

Roller mechanism 34a is equipped with hollow pipe 182, and this pipe 182 is formed with a plurality of hole 184a to 184e, forms material so that supply with protective layer to roller 48.Hole 184a to 184e has identical opening diameter, and along arranging with interval H1 to H4 from arrow B 1 direction of first end 112a to the second end 112b.Near the hole 184e of the second end 112b and the interval H4 between the 184d less than near the hole 184a of the first end 112a and the interval H1 between the 184b.Interval H1 to H4 between the 184a to 184e of hole for example is arranged so that H1=H2＞H3＞H4.

Roller mechanism 34a by such formation; near the hole 184e of the second end 112b and the interval H4 between the 184d less than near the hole 184a of the first end 112a and the interval H1 between the 184b; like this, protective layer formation material can evenly apply from hole 184a to 184e per unit area along the axial direction of pipe 182.Like this, can be in the axial direction evenly supply with protective layer and form material, thereby obtain the effect identical with roller mechanism 34 along the whole length of roller 48.

In addition, in being equipped with pipe 112 roller mechanism 34, having the hole 114a to 114e that sets diameter D1 to D5 and can have and be arranged to and roller mechanism 34a identical distance H1 to H4.

Below with reference to Figure 13 and Figure 14 introduction roller mechanism 34b according to the second optional embodiment of roller mechanism 34.Roller mechanism 34b and roller mechanism 34 are similar, and its middle roller 48 is replaced by roller 148.

As Figure 13 and shown in Figure 14, roller 148 is by roller mechanism 34b supporting, thereby this roller can rotate freely and be equipped with: cylindricality brush pedestal 118a, protective layer form material and are supplied among this cylindricality brush pedestal 118a; And brush (applicator) 118b, it is arranged on the excircle of brushing pedestal 118a and with the surface of vehicle 14 and closely contacts, and forms material thereby apply protective layer.

Brush pedestal 118a is made by lightweight material, for example soaks into the paper that plastic material (for example phenol) is arranged.For the protective layer formation material that will supply among the brush pedestal 118a is delivered to brush 118b, in axial direction (direction of arrow B) forms a plurality of threaded hole 119 in the excircle of brush pedestal.Each hole 119 has and for example is the diameter D of 1.8mm and the spacing P of 20mm.

By roller mechanism 34b, when roller 148 rotations formed material to apply protective layer, protective layer formed material can in axial direction supply to rotation roller 148 equably with radial direction brush 118b.Therefore, protective layer forms material can be evenly and supply to reliably and apply the surface, therefore can realize that effective and high-quality protective layer forms the coating operation of material with simple structure.

In addition, brush pedestal 118a has the paper of plastic material to make by infiltration, and therefore, brush pedestal 118a is light and economical, and the intensity of brush pedestal 118a self can increase effectively.

Below with reference to the roller mechanism 34c of Figure 15 description according to the 3rd optional embodiment of roller mechanism 34.Roller mechanism 34c and roller mechanism 34 are similar, and its middle roller 48 is replaced by roller 212.

Roller mechanism 34c is so that roller 212 can free rotation mode support this roller 212; and the brush pedestal 118a as the part of roller 212 has a plurality of holes 214, and the protective layer that these holes 214 are used for being supplied with forms material and is delivered to brush pedestal 118a.Hole 214 becomes lattice structure in the axial direction upper edge outer circumferential of brush pedestal 118a.Each hole 214 has and for example is the diameter D of 1.8mm and the pitch P that has 20mm between hole adjacent one another are 214.

By the roller mechanism 34c of such formation, so that when applying protective layer and forming material, the brush zone 118b of rotation roller 212 can evenly apply protective layer with circumferential direction vertically and form material when roller 212 rotation.Therefore, similar with the effect of roller 34b, protective layer formation material can evenly and reliably be supplied to be applied on the surface, therefore can realize that effective and high-quality protective layer forms the coating operation of material by simple structure.

Below with reference to the roller mechanism 34d of Figure 16 to Figure 18 description according to the 4th optional embodiment of roller mechanism 34.Roller mechanism 34d has collar member 124, and this collar member 124 is added on the roller 48 of roller mechanism 34d.

Shown in Figure 16 to 18, collar member 124 is arranged between pipe 112 and the roller 48.In order to make collar member 124 lighter, for example collar member 124 is made of plastics and has radially a plurality of (for example two) part 126a, the 126b that divides.The slit shape groove 128a, the 128b that extend along the axial direction (along the direction of arrow B among Figure 17) of roller 48 are formed between part 126a, the

126b.Groove

128a, 128b form fixing width gap S (with reference to Figure 18).

In roller mechanism 34d, the first end 112a of pipe 112 is connected with conduit 22, and the protective layer of being supplied with by conduit 22 forms material by flowing in the collar member 124 in the hole 114 of managing in 112.

Protective layer forms material and radially is sent to the roller 48 from

groove

128a, 128b with axial direction, and making protective layer form material can evenly be supplied with along the axial direction of whole roller 48.Therefore, can realize that effective and high-quality protective layer forms material and applies operation by simple structure.

And in the roller 48, therefore, the aequum that the protective layer that needs in roller 48 forms material is replenished fast because collar member 124 is packed into.This is because the free space in roller 48 inside reduces greatly.Therefore, compare, can be used for the high response coating operation that protective layer forms material effectively with the structure of not using collar member 124.

In addition, because between divided

portion

126a, 126b, be formed with

groove

128a, 128b, thus the designs simplification of collar member 124, thus make collar member 124 to be made more economically.

In addition, for example need not arrange bearing between pipe 112 and end cap 122, therefore whole roller mechanism 34d can make forr a short time and be lighter.And, the decreased number of member, so roller mechanism 34d can be made economically.

Because collar member 124 can be divided into two

part

126a and 126b, therefore inner surface can be cleaned and be easy to assembling.In other words, when assembled

portion

126a and 126b, pipe 112 places between part 126a and the 126b simply.

Below with reference to the roller mechanism 34e of Figure 19 to Figure 21 description according to the 5th optional embodiment of roller mechanism 34.Roller mechanism 34e and roller mechanism 34d are similar, wherein are provided with bullport 188,188a, 190,190a in collar member 124.

As shown in Figure 19 to Figure 21, radially a plurality of bullports (opening) 188,190 that penetrate from the center of collar member 124 are formed at part 126a, the 126b of roller mechanism 34e.Bullport 188,190 is staggered along the outer wall of

part

126a, 126b, and in axial direction distributes equably.

In a plurality of bullports 188, in axial direction 189 tilt towards the end to outer surface at the bullport 188a at part 126a two ends, and 189 places have opening in the end from inner surface.Equally, in a plurality of bullports 190, in axial direction 191 tilt towards the end to outer surface at the bullport 190a at part 126b two ends, and 191 places have opening in the end from inner surface.

By the roller mechanism 34e of such formation, the protective layer of being supplied with by conduit 22 forms material and flows to collar member 124 from the hole 114 of managing 112.At this moment, the slit groove 128a, the 128b that extend along the axial direction of roller 48 are formed between part 126a, the 126b (this

part

126a, 126b form collar member 124), and

part

126a, 126b have a plurality of bullports 188,190 that radially penetrate.

Therefore, protective layer forms material and is transported in the roller 48 along

groove

128a, 128b, and because the centrifugal force that collar member 124 rotations cause and flowing in the roller 48 by a plurality of bullports 188.Therefore; protective layer forms material and can reliably and equably be supplied with in the axial direction along the whole length of roller 48; therefore, similar with the effect of roller mechanism 34d, can realize that effective and high-quality protective layer forms the coating operation of material by simple structure.

In addition; two part 126a that form collar member 124 are equipped with bullport 188a and the 190a that is connected with 191 with outer surface end 189 with 126b; therefore; the 114 protective layers formation materials that flow out flow through

bullport

188a and 190a from the hole; supplied to the two ends (end 189,191 of

part

126a, 126b just) of collar member 124 reliably, soaked into then to the two ends of applicator 48a.Therefore, can prevent the two ends desiccation of applicator 48a.

Therefore, protective layer forms material will infiltrate into applicator 48a in even mode, thereby form the coating that consistent protective layer forms material on vehicle 14.And, can not produce inhomogeneous applying.

In addition, 188a is similar with bullport, as shown in figure 22, also in axial direction 189 is tilting towards the end to outer surface from inner surface than the bullport 188b of the regional split shed at more close a little center, end 189.Equally, 190a is similar with bullport, also can tilt at the bullport 190b than the regional split shed at more close a little center, end 191.Therefore, can more positively prevent the regional desiccation of the end 189,191 of close collar member 124.

As shown in figure 23, all bullport 188c, 190c can both tilt symmetrically with respect to the central area, and are identical shaped if all bullport 188c have like this, and the process of then cutting and form bullport 188c will become easy.

In addition, as shown in figure 24,

bullport

188d and 190d can be from inner surface to outer surface 189 formation towards the end in axial direction with bend mode.As shown in figure 25, bullport 188e can have spiral-shaped, in axial direction distortion.

Below with reference to the roller mechanism 34f of Figure 26 description according to the 6th optional embodiment of roller mechanism 34.Roller mechanism 34f has

curved guide hole

198 and 199, to replace the bullport 188,190 among the roller mechanism 34e.

As shown in figure 26, a plurality of curved guide hole (opening) 198,199 that radially penetrates from the center of collar member 124 is arranged on part 126a, the 126b of roller mechanism 34f.Curved guide hole 198,199 is staggered in the perimeter of

part

126a, 126b, and in axial direction evenly distributes.

By the roller mechanism 34f of such formation, a plurality of curved guide hole 198,199 is arranged among part 126a, the 126b of roller mechanism 34f.Therefore, protective layer forms the amount that material applies and can change, and can apply the surface and carry out favourable coating operation specific.Therefore, bullport 188,190 by using roller mechanism 34e selectively and the curved guide hole 198,199 of roller mechanism 34f can effectively be used for the various required coatings operations that apply the surface.Should be known in for

roller mechanism

34e, 34f, any

groove

128a, 128b must be provided.

Below with reference to the roller mechanism 34g of Figure 27 to 30 description according to the 7th optional embodiment of roller mechanism 34.

The rack body 86e of roller mechanism 34g has a plurality of first through hole 87a, and these first through holes 87a penetrates into roller 48 sides from anchor clamps 104 sides that are installed in the top, and each first through hole 87a forms and has specific interval.The size and the number that should be noted that the first through hole 87a can be provided with according to the shape of rack body 86e.

On the other hand, the second approximate rectangular through hole 87b is formed near the center of fixed support 86a and travel(l)ing rest 86c.The first and

second hole

87a, 87b for example can form by punching processing.

And the first through hole 87a and the second through hole 87b that are formed among rack body 86e, fixed support 86a and the travel(l)ing rest 86c are not limited to through hole, also can be the recessed zones that has the bottom with suitable dimension and degree of depth.

A pair of inclined-plane (otch) 89a is formed at the end side of the fixed support 86a of support column 112 with fixing angle of inclination, so width is towards end narrow down (with reference to Figure 27).

A pair of inclined-plane (otch) 89b is formed at the end side of the travel(l)ing rest 86c of support column 112 with the constant tilt angle, so width is towards end narrow down (with reference to Figure 29).The angle of inclination of inclined-

plane

89a, 89b cuts into such angle, promptly contacts with the surface of vehicle 14 so that when applying protective layer and forming material when the roller in support connector 88 48, and the end of support 86 can not contact with the surface of vehicle 14.Should be noted that to form at inclined-plane 89a on the fixed support 86a and inclined-plane 89b on travel(l)ing rest 86c makes them be approximately identical angle.Should be noted that inclined-

plane

89a, 89b play the effect interfered of preventing, interfere with vehicle 14 so that prevent.

In addition, as inclined-

plane

89a, 89b on fixed support 86a and the travel(l)ing rest 86c are cut into leg-of-mutton replacement method, the end of fixed support 86a and travel(l)ing rest 86c can form taper shape.Therefore, identical with the situation of inclined-

plane

89a, 89b, can prevent that support 86 from contacting with the surface of vehicle 14.

By in the rack body 86e of support 86, forming a plurality of first through hole 87a or having the recessed zone of bottom and in fixed support 86a and travel(l)ing rest 86c, form the second through hole 87b or have the recessed zone of bottom, can alleviate the weight of the support 86 of roller mechanism 34g.Therefore, because the weight of support 86 reduces, can reduce with the moment of inertia of pivot 82 as the pivot generation of fulcrum by support connector 88.Therefore, support connector 88 can pivot easier and more smoothly, and the control of the pivot of roller mechanism becomes easy.

Should be noted that can be so that rack body 86e, fixed support 86a and travel(l)ing rest 86c be thinner to reduce weight, and but, this greatly reduces the second moment in cross section, thereby makes intensity become not enough.On the other hand, by forming the first through hole 87a, the second through hole 87b or the recessed zone at the end being arranged, can suppress the reducing of second moment (the moment of inertia) in cross section, thereby in weight reduction, keep intensity.

In addition, by inclined-plane 89a, the 89b that tilts with fixed angle in the end cutting of the travel(l)ing rest 86c of support 86 and fixed support 86a, when support connector 88 utilizes pivot 82 only to pivot a specified angle as fulcrum, can prevent that the support 86 of support connector 88 from contacting with the surface of vehicle 14.In other words, when alleviating support 86 weight,, roller 48 can prevent that support 86 from contacting with vehicle 14 when protective layer forms material when being used to apply by inclined-

plane

89a, 89b.

The combination that should be noted that the part of functions of utilizing roller mechanism 34 to 34f also is fine certainly.

Form peelable protective layer that material forms by protective layer and can transport the back protection zone of having sprayed paint, can in factory, protect the zone of having sprayed paint equally, also can be used as the substitute of scratch resistant lid at vehicle 14.Therefore, can save be used for various type of vehicle, have difform a plurality of scratch resistant lid.

In addition, though some shock absorbers of vehicle 14 have color and therefore do not need to spray paint, protective layer forms material and also can be applied on the part of not spraying paint, for example shock absorber.

Although described embodiments of the invention, it will be appreciated by those skilled in the art that under the situation that does not break away from spirit of the present invention or essence and can change and change.Scope of the present invention is limited by accessory claim.
