Shown in Fig. 4 (d) and 4 (e), during the application object 50, make object 50 and spray gun displacement with predetermined direction (promptly opposite direction) with arrow S, keep object 50 constant simultaneously with the relative position of spray gun.
Thereafter, shown in Fig. 4 (f) and 4 (g), when with opposite directions, when moving back and forth object 50 and spray gun with the method for synchronization, when finishing the first half round trips and the second half round trips at every turn, object 50 is with the predetermined distance that is shifted successively of direction shown in the arrow S, and continues the layer application of coating material.Shown in Fig. 4 (h), when moving back and forth object 50, finish application fully by spray pattern 31.
By in opposite directions as mentioned above, carry out application when moving back and forth object 50 and spray gun with the method for synchronization, can reduce reciprocal starting position of object 50 and the distance between the completing place.This has further reduced object 50 in the required space of vibration-direction application.
In the present embodiment, the direction of displacement of object 50 and spray gun 30 is opposite with the direction shown in the arrow S; Yet direction is not limited to this, as long as can reduce the required space of application.
In the present embodiment, when from the center of the spray pattern 31 of spray gun 30 spraying basically at object 50 with in the middle of direction shown in the arrow S vertical the time, object 50 and spray gun 30 are shifted; Yet be not limited to this opportunity of displacement.
In the present embodiment, shown in Fig. 3 (c), the operation of controller control object conveyer and spray gun conveyer makes object 50 and spray gun 30 displacements once; Yet the number of times of displacement is not limited to once, and this operation can be so that more than 30 displacement of object 50 and spray gun.
In addition, in the present embodiment, the operation of controller control object 50 makes object 50 when finishing each half round trip of described object 50 as shown in Figure 3, successively with the displacement of direction shown in arrow S preset distance.Yet, can also control and make object 50 with particular constant speed, with direction shown in arrow S displacement, move back and forth object 50 simultaneously.

The method of control particle diameter, concentration and speed of atomization particle from the spray pattern of the coating material of spray gun 30 sprayings below is described.Atomizing particle size is the average grain diameter the coating material atomization particle group who measures near the site of object 50, and described coating material is with spray gun 30 atomizings.Particle diameter can be used measurements such as laser diffraction granularity analyzer.Atomization particle concentration is long-pending by the overall particle of unit are spray pattern.As the method for simplifying, it is the average atomizing particle concentration that atomization particle concentration can be used as, and it calculates divided by the spray pattern area with the coating material flow velocity.First-class by spray pattern is sprayed onto plate, can obtain the spray pattern area easily.Atomization particle speed is when atomization particle arrives the site of object 50, the averaged particles speed of population in object 50 directions.Atomization particle speed can be with measurements such as laser Doppler velocimeters for example.
When using revolution bell atomization spraying device as spray gun 30, clock cup diameter, the rotating speed of clock and the flow velocity of coating material etc. by suitable selection revolution bell atomization spraying device, can easily set particle diameter, make particle diameter basically with actual application operation in identical.For example, can be by changing the rotating air pressure of clock of revolution bell atomization spraying device 30, the rotating speed of control clock.Can be by changing the flow velocity of coating material feedway, the flow velocity of control coating material.Usually, the revolution bell atomization spraying device that is used for actual application operation has the clock cup diameter of about 60mm φ to 70mm φ, and its speed of gyration is 20000-30000rpm, and flow velocity is 200 to 300 cc/min; Yet, when using little clock cup in the present embodiment, can under the speed of gyration of the flow velocity that reaches about 20 to 30 cc/min less and about 10000rpm, obtain to operate identical particle diameter with actual application basically.
When using air atomization coating equipment as spray gun 30, the flow velocity by suitably selecting atomization air flow speed, coating material etc. can be set particle diameter easily, thus basically with actual application operation in identical.Can pass through the volume of minimizing discharge air etc., control atomization air flow speed.
By spray pattern,, can easily calculate atomization particle concentration based on the flow velocity of coating material with respect to the spray pattern area that forms on the object 50 from spray gun 30 sprayings.Therefore, by control coating material flow velocity, can obtain easily basically with actual application operation in identical atomization particle concentration.For example, when the width of application pattern in the practical operation be 30 centimetres, when flow velocity is 200 cc/min, if the width of application pattern is set at 10cm in the present embodiment, the pattern area ratio of present embodiment/practical operation is 1/9.Therefore, be 22.2 cc/min (200 * (1/9)) by setting flow velocity, can obtain identical atomization particle concentration.Please note angle and its flow velocity of the shaping air that sends from revolution bell atomization spraying device by control, can change the width of spray pattern easily.
When using revolution bell atomization spraying device as spray gun 30, the shaping air velocity by suitably selecting revolution bell atomization spraying device, application distance etc., can make easily atomization particle speed basically with actual application operation in identical.Please note when using air atomization coating equipment,, can easily make atomization particle speed identical with actual application operation basically by suitably selecting atomization air flow speed and application distance as spray gun 30.
As mentioned above, flow velocity, the application distance of the coating material by control spray gun 30 etc., the atomization condition (particle diameter of atomization particle, concentration and speed) that can make coating material basically with actual application operation on object 50 coating material of deposition identical.
Below the method for spray gun 30 and object 50 relative motions is controlled in explanation.Particularly, the forming process of filming during definite actual application is operated based on the relation between the variation of film formation time and gained coating thickness, the relative motion of control spray gun 30 and object 50.
Below with reference to Fig. 5 and Fig. 6 the forming process of filming in the actual application operation is described.Fig. 5 is a key diagram, has showed in the actual application step path of spray gun 100 on little area portions 103 of object 101.Fig. 6 is a key diagram, illustration the relation between elapsed time (elapse time) and the coating thickness in little area portions 103.
Among Fig. 5, spray gun 100 is connected to and vertically moves back and forth element 102, and coating material is sprayed on the object of wanting application.In this embodiment, spray gun 100 by seven times, makes spray pattern be coated seven times on little area portions 103 of application object 101, and formation is filmed.
With little area portions 103 pass through length L 1 divided by reciprocating motion speed, can calculate along with spray gun 100 by little area portions 103 once, the sedimentation time of atomization particle (floattime) is (TF).The spray gun 100 also part beyond little area portions 103 moves back and forth.Revolution bell atomization spraying device 100 is by the duration of part beyond little area portions 103, promptly finish in little area portions 103 behind the application path interval T I, can calculate with formula TI=(move back and forth the little area portions 103 of width L2-pass through the distance L 1)/speed of moving back and forth to follow-up application path.Therefore, can with representative film formation time trunnion axis and represent the vertical axis acquisition of the coating thickness forming process of filming as shown in Figure 6.Measurements such as the thickness of filming can electricity consumption magnetic coating thickness meter, laser instrument detector for displacement measuring.Among Fig. 6, schematically show film thickness, but in the actual application operation, film deposits based on logarithmic function with straight line.
Controller is regulated object conveyer 41, so that produce the coated film forming process, it is determined by the relation between the variation of coated film formation time and the coated film thickness that obtains.In other words, the control of object conveyer 41 depends on object 50 passes through from the coating material spray pattern of spray gun 30 spraying duration, number of times that object 50 passes through and finishes an application and transmit and begin the interval T I of application subsequently between transmitting, and makes these consistent with the forming process of filming during actual application is operated.Please note control object conveyer 41,, make that during interval T I, the atomization particle of coating material is not deposited on the object 50 by object 50 being statically placed in or the zone of mobile object 50 between the application that does not deposit the coating material atomization particle.
This makes and to be deposited on the object 50 substantially the same (behavior of film deposition) and actual application from coating material atomization particle of spray gun 30 sprayings.
When actual application operation is undertaken by 2-stage application, i.e. coated film forming process as shown in Figure 9, object is crossed application after carrying out application in advance, the sudden strain of a muscle break time of not carrying out application (flash time) of finishing application and providing between the beginning application in second step in first step.When using twice application to carry out application in the actual application operation with a sudden strain of a muscle break time, so that meet the opportunity of dodging the break time, can make from the coating material atomization particle deposition (deposition behavior) of revolution bell atomization spraying device 30 sprayings identical with actual application operation basically on object 50 by suitably setting interval T I.
In with coating material application object three times or multistage application more frequently, make it meet a plurality of the sudden strains of a muscle break time by suitably setting interval T 1, can make deposition properties basically with identical during actual application is operated.
As mentioned above, the film formation device 1 of present embodiment can be by air themperature and the humidity in 22 between the control application, control is from particle diameter, concentration and the speed of the coating material atomization particle of spray gun 30 sprayings, and control is deposited on the atomization particle deposition behavior on the object 50, make they basically with actual application operation in identical, reproduce the application condition in the actual application operation.Therefore, can form the substantially the same coated film that obtains in final mass and the actual application operation.
