Description

The present disclosure relates to a method and system for applying a non-Newtonian fluid such as a sealing material using a coating roller.

When assembling the structural members of an aircraft, a sealing material is applied to the joint surface between the members based on the requirements for waterproofing and corrosion resistance. For example, the sealing material is spread on the joint surface while rotating the roller with respect to the joint surface to which the sealing material is supplied.
It is difficult to stabilize the coating state of the sealing material on the joint surface due to the variation in the physical properties of the sealing material depending on the environmental temperature at the time of coating. Therefore, the coating work of the sealing material using the rollers is performed by hand while checking the state such as the thickness of the layer formed by the sealing material on the joint surface.
Since the viscosity of the sealing material changes depending on the environmental temperature, it is confirmed that the environmental temperature is within the allowable temperature range specified for the sealing material during the coating operation.

Although there are few examples of attempts to automate the coating of the sealing material by the coating device, Patent Document 1 discloses a sealing material coating device applicable to the stringer of an aircraft. Such a sealing material coating device has a sealing material coating mechanism mounted on a trolley that is suspended from a frame and can travel along a rail and can move up and down, and a contact pressure between a work such as a stringer and the sealing material coating mechanism. It is equipped with a work support positioner that can be used. The sealant coating mechanism includes a sealant feeder and a serrated sealant leveling roll arranged in series with the feeder. This sealing material application mechanism travels according to the shape of the work, and while pressing the smoothing roll against the work, the sealing material supplied to the joint surface by the feeder is evenly distributed to each saw tooth of the smoothing roll. The running speed is synchronized with the peripheral speed of the break-in roll.

As described above, it is difficult to put into practical use a coating system that automates the sealing material coating process because the variation in the physical properties of the sealing material due to the environmental temperature and the like affects the coating state of the sealing material. It relies on human hands.
In order to ensure the joining quality between the members that are assembled with the sealing material intervening, we want to apply the sealing material to the joint surface with a stable thickness.

According to a skilled worker, while checking the viscosity of the sealing material discharged from the dispenser and the condition of the applied sealing material, the pressing force of the roller against the joint surface, the speed at which the roller is moved, and the roller as necessary It is possible to stabilize the coating state by adjusting the number of reciprocating operations based on experience.
However, in addition to the need to secure skilled workers, there is a limit to the speed of the coating work even for skilled workers as far as manpower is concerned. Considering the current situation in which the coating state is stabilized by adjusting the roller speed while checking the state of the sealing material each time the coating work is performed, it is difficult to meet the demand for productivity improvement by speeding up the coating process.

Based on the above, the present disclosure provides methods and systems capable of speeding up the coating process by automating the coating of non-Newtonian fluids by realizing stable coating of non-Newtonian fluids such as sealing materials by the coating system. The purpose is to provide.

In studying the coating conditions for achieving automation and high speed, the inventor examined the physical phenomenon that the sealing material supplied to the outer peripheral surface of the roller adheres to the joint surface as the roller rotates. .. Even if the sealing material is stably supplied to the outer peripheral surface of the roller, if the sealing material does not stably adhere to the joint surface, the thickness of the sealing material adhered to the joint surface is also not stable. If a layer having a stable thickness of the sealing material can be obtained by performing the process of rolling the roller from one end to the other end of the joint surface only once, it contributes to speeding up the coating process.

The inventor of the present disclosure is related to the ease of peeling of the sealing material and the speed of application because the sealing material is a non-Newton fluid and there is a relationship between the shear stress of the flow and the speed of the flow. Focusing on the fact that there is, we came up with new coating conditions necessary to obtain a sealing material with a stable thickness on the joint surface.

The non-Newtonian fluid coating method of the present disclosure including such coating conditions is a method of applying a non-Newtonian fluid to a target region using a coating roller that rolls the target region of the target member, and is a non-Newtonian fluid including the coating roller. The coating system rotates the coating roller at a predetermined roller speed corresponding to the peripheral speed of the coating roller corresponding to the temperature characteristics of the non-Newtonian fluid, and at the same time, the target member and the coating roller are driven at a coating speed corresponding to the roller speed. A coating step is provided in which the non-Newtonian fluid is applied from the coating roller to the target area while being relatively moved while supplying the non-Newtonian fluid to the outer peripheral portion of the coating roller.
When the roller speed is _VR and the non-Newtonian fluid has a certain temperature and a certain viscosity, the speed at which the non-Newtonian fluid separates from the outer peripheral portion of the coating roller prior to reaching the target region due to the rotation of the coating roller is _VG . Assuming that the velocity at which the non-Newtonian fluid that has reached the region leaves the outer peripheral portion of the coating roller is _VS , the relationship of _VG < _VR < _VS is established.

Further, the non-Newtonian fluid coating system of the present disclosure is a system for coating a non-Newtonian fluid on a target region by using a coating roller that rolls on the target region of the target member, and is a coating corresponding to the temperature characteristics of the non-Newtonian fluid. A coating roller that is rotationally driven at a predetermined roller speed corresponding to the peripheral speed of the roller and is moved by a moving mechanism with respect to the target member at a coating speed corresponding to the roller speed, and a non-Newtonian fluid is applied to the outer periphery of the coating roller. It is equipped with a supply mechanism that supplies the unit.
When the roller speed is _VR and the non-Newtonian fluid has a certain temperature and a certain viscosity, the speed at which the non-Newtonian fluid separates from the outer peripheral portion of the coating roller prior to reaching the target region due to the rotation of the coating roller is _VG . Assuming that the velocity at which the non-Newtonian fluid that has reached the region leaves the outer peripheral portion of the coating roller is _VS , the relationship of _VG < _VR < _VS is established.

According to the present disclosure, as will be described in detail later, the coating roller is rotationally driven at a roller speed _VR corresponding to the temperature characteristics of the non- _Newtonian fluid based on _VG < _VR <VS. Non-Newtonian fluid can be applied to the target area to a stable thickness even if it is applied once, regardless of variations in physical properties such as viscosity due to the temperature of the sealing material, so that non-Newtonian fluid application can be automated and speeded up. Can be planned. According to the present disclosure, it is possible to realize a coating speed that greatly exceeds the speed by manual work.
As will be described later, the applicable speed of the coating roller for each temperature of the sealing material is faster as the temperature of the sealing material is higher. Therefore, if the coating operation is performed at a relatively high temperature, the sealing material can be applied to the target member while rolling the coating roller at high speed, so that the time required for the coating process can be shortened. In particular, it is preferable to perform the coating operation at a temperature close to the upper limit of the temperature allowed for the sealing material at the time of coating from the viewpoint of shortening the coating process. Further, the higher the temperature of the sealing material, the wider the applicable speed range for each temperature, so that the degree of freedom of the device for driving the coating roller or the like is high.

Hereinafter, embodiments will be described with reference to the accompanying drawings.
The present embodiment discloses a method and a system for applying the sealing material 3 to the member 2 using the coating roller 11, and a method for acquiring the speed of the coating roller 11.
According to the sealing material coating system 1 (FIGS. 1 to 3) disclosed below, the sealing material 3 can be applied to the member 2 constituting the airframe of the aircraft as an example of the target member.

[Material to be applied]
The member 2 corresponds to, for example, the stringer 2-1 shown in FIG. 6A or the frame 2-2 shown in FIG. 6B. Both the stringer 2-1 and the frame 2-2 are structural members of the aircraft and are joined to skins (not shown). The cross-sectional shape of the stringer 2-1 is just an example.
Due to the requirements for waterproofing and corrosion resistance, for example, after applying the sealing material 3 to the target area 2A of the stringer 2-1 the stringer 2-1 and the skin are joined by an appropriate method such as fastening.
As shown in FIG. 4, the positioning member 9 can position the member 2 at a predetermined position.
When the sealing material 3 is applied to the target area 2A, which is the joint surface of the structural member of the aircraft, it is required that the sealing material 3 is applied over the entire target area 2A.

[Seal material]
The sealing material 3 is applied to the target region 2A of the member 2 when it contains an appropriate dispersoid selected from the viewpoint of weather resistance and the like and a dispersion medium and has fluidity before curing. .. At the time of application, the sealing material 3 corresponds to a non-Newtonian fluid exhibiting viscosity.
The target area 2A of the member 2 and the target area of the corresponding member (for example, a skin) are sealed by the sealing material 3 being cured by drying or the like.

The temperature of the sealing material 3 is basically close to the temperature of the environment in which it is used, and the physical properties including the viscosity of the sealing material 3 change according to the temperature of the sealing material 3. According to the present embodiment, as will be described later, the roller speed at the time of coating is determined from the relationship between the ease of peeling of the sealing material 3 from the coating roller 11 and the speed of the coating roller 11 according to the temperature characteristics of the sealing material 3. By deriving _VR , the state of application of the sealing material 3 to the target area 2A can be stabilized and the bonding quality can be improved.

In addition to the sealing function, the sealing material 3 may have an adhesive function of joining members to each other by an adhesive force. In that case, the members are joined to each other as the sealing material 3 is cured between the members. At this time, with the members positioned, pressurization and heating may be performed as necessary.

In the present embodiment, the sealing material 3 is enclosed in a cylinder-shaped container 3C (FIGS. 1 and 2) and stored under temperature control. The container 3C is provided with a nozzle 31 for discharging the sealing material 3 on the coating roller 11. When the container 3C is opened before use, the container 3C is detachably attached to the moving body 40 including the coating roller 11. When replacing the container 3C with a new container 3C, the nozzle 31 and the piston shape inserted into the container 3C in order to prevent the sealing material of the used container 3C from being mixed with the sealing material of the new container 3C. All the members with which the sealing material 3 comes into contact, including the extrusion portion 32 and the coating roller 11 of the above, are cleaned. In addition, even at the time of periodic inspection, the path in contact with the sealing material 3 including the nozzle 31 and the coating roller 11 is cleaned.

[Seal material application system]
In the sealing material coating system 1 (hereinafter referred to as coating system 1) shown in FIGS. 1 to 3, the sealing material 3 is applied to the target area 2A by using the coating roller 11 that rolls the target area 2A of the member 2.
As used herein, the terms "front" and "rear" refer to the front and rear of the direction in which the coating roller 11 rolls (rolling direction D1) with respect to the position of the coating roller 11.

As shown in FIGS. 1 to 3, the coating system 1 supplies the coating roller 11, the supply roller 12 arranged in front of the coating roller 11, and the sealing material 3 to the outer peripheral portion 11A of the coating roller 11. 30, a moving body 40 including the coating roller 11 and the supply roller 12, a control unit 6 for controlling the rotational drive of the coating roller 11 and the supply roller 12, and a temperature adjusting mechanism 7 for adjusting the sealing material 3 to a predetermined temperature. It is equipped with.
By driving the moving mechanism 8 by the control unit 6 or another control unit (not shown), the moving body 40 provided with the coating roller 11 is sent to the member 2 at the moving speed.

Further, it is preferable that the coating system 1 includes a pressurizing mechanism 41 that presses the coating roller 11 and the target region 2A into contact with each other, and a following mechanism 43 that causes the coating roller 11 to follow the shape change of the member 2. The pressurizing mechanism 41 and the following mechanism 43 can be provided on the moving body 40 as in the present embodiment.

The setting of the roller speed _VR corresponding to the temperature characteristic of the sealing material 3 will be described. The roller speed _VR corresponds to the peripheral speed of the coating roller 11. Since the peripheral speed can be converted from the rotation speed, diameter, and pi of the coating roller 11, the rotation speed as the roller speed corresponding to the temperature characteristics of the sealing material 3 is obtained, and the rotation speed is used to obtain the rotation speed of the coating roller 11. It may be converted into the peripheral speed of.
When the sealing material 3 has a certain temperature T and a certain viscosity η, the relationship between the ease of peeling of the sealing material 3 from the coating roller 11 and the speed of the coating roller 11 is expressed by the following formula (1). _VG < _VR < _VS (1)
_VG : Speed at which the sealing material 3 separates from the outer peripheral portion 11A of the coating roller 11 prior to reaching the target area 2A due to rotation of the coating roller 11 _VR : Speed corresponding to the peripheral speed of the coating roller 11 _VS : The speed at which the sealing material 3 that has reached the target area 2A separates from the outer peripheral portion of the coating roller 11.

Here, _VG is a speed that is relatively determined in relation to _VR due to the physical properties of the sealing material 3. , _VS is also a speed that is relatively determined in relation to _VR due to the physical properties of the sealing material 3. _VG and _VS can be derived by testing and analysis.
When _VG < _VR , the sealing material 3 can stay in the outer peripheral portion 11C without being separated from the coating roller 11 by gravity, centrifugal force, or the like prior to reaching the target region 2A.
Further, when _VR < _VS , the sealing material 3 that reaches the target area 2A and exerts gravity, centrifugal force, adhesion to the target area 2A, and the like can be separated from the outer peripheral portion of the coating roller 11. ..
For example, when the coating test is performed at different roller speeds _VR , the relationship between _VG and _VR is reversed from the equation (1), and the relationship between _VR and _VS is the equation (1). If it is reversed, it will be difficult to stabilize the coating state.

From the above equation (1), the range of the roller speed _VR (speed range _SR ) between _VG and VS is derived. The roller speed _VR is determined in this range. The speed range SR and the roller speed _VR can be stored in the storage medium of the control unit 6.
It is preferable that the roller speed _VR is sufficiently larger than _VG and sufficiently smaller than _VS. For example, the center value from _VG to _VS can be set for the roller speed _VR .

FIG. 7A schematically shows the behavior of the flow of the sealing material 3 when the coating roller 11 is rotationally driven at the set roller speed _VR .
7A and 7B and 7C, which are comparative examples, show an example in which the supply roller 12 is arranged adjacent to the front of the coating roller 11. Even when the supply roller 12 does not exist and the sealing material 3 is directly supplied from the nozzle 31 to the outer peripheral portion 11A of the coating roller 11, the sealing material 3 is shown in FIGS. 7A, 7B, and 7C, respectively. It shows the same behavior as.

In FIGS. 7A, 7B, and 7C, the outer peripheral portion 11C of the coating roller 11 is the target region 2A from the position of the nozzle 31 and the gap 13 between the coating roller 11 and the supply roller 12 in the rotating coating roller 11. Corresponds to the range up to. The above-mentioned outer peripheral portion 11A is located above the position where the sealing material 3 is supplied to the outer peripheral portion 11C through the nozzle 31 and the gap 13.

When the relationship of the above formula (1) holds, as shown in FIG. 7A, the sealing material 3 forms a layer 3L1 having a stable thickness in the outer peripheral portion 11C below the gap 13, and R1 of the coating roller 11. When the layer 3L1 comes into contact with the target region 2A as it rotates in the direction, it separates from the coating roller 11 and forms a layer 3L2 having a stable thickness even in the target region 2A. At this time, the thickness t1 of the layer 3L1 and the thickness t2 of the layer 3L2 are equivalent.

The case where the above equation (1) does not hold will be described with reference to FIGS. 7B and 7C. If the formula (1) does not hold, even if the sealing material 3 is supplied to the outer peripheral portion 11A of the coating roller 11 in a stable supply amount (supply amount per unit time), the viscosity of the sealing material 3 due to the temperature, etc. The coating state of the sealing material 3 is not stable because the variation in the physical properties of the sealing material 3 has a large influence on the flow state of the sealing material 3.

As shown in FIG. 7B, when _VR is sufficiently smaller than _VG ( _VR << _VG ), the roller speed _VR is slower than that in FIG. 7A, so that the sealing material adhered to the outer peripheral portion 11C. 3 separates from the outer peripheral portion 11C due to gravity, centrifugal force, or the like and flows down prior to reaching the target region 2A due to the rotation of the coating roller 11. Since the behavior of the sealing material 3 that flows down is unstable, it is difficult to stabilize the thickness t1 of the sealing material 3 in the outer peripheral portion 11C. Then, it is difficult to stabilize the thickness t2 of the sealing material 3 adhering to the target region 2A. Since the relationship between t1 and t2 is t1> t2 or t1 <t2, the thickness of the layer 3L2 of the sealing material 3 on the target region 2A varies widely.

Next, as shown in FIG. _7C , when _VR is sufficiently larger than VS (VS _{<< VR} ), the roller speed _VR is faster than that in FIG. 7A, so that it adheres to the outer peripheral portion 11C. Before the sealing material 3 is separated from the coating roller 11 by contact with the target region 2A, the sealing material 3 is separated from the target region 2A by the rotation of the coating roller 11. Since the behavior of the sealing material 3 is unstable when the sealing material 3 does not separate from the coating roller 11 even if it comes into contact with the target area 2A in this way, the coating roller 11 moves to the target area 2A as in the example shown in FIG. 7C. Even if a part of the sealing material 3 is transferred, it is difficult to stabilize the thickness t2 of the sealing material 3.

For example, only a part of the sealing material 3 adhering to the outer peripheral portion 11C is transferred to the target region 2A, and the remaining sealing material 3 is left at the same location (outer peripheral portion 11C') even if it passes through the target region 2A. In this case, the relationship between the thickness t1 of the sealing material 3 in the outer peripheral portion 11C and the thickness t2 of the sealing material 3 adhering to the target region 2A is t1> t2. Can not be covered by the sealing material 3, and a part of the target area 2A may be exposed.

If the roller speed _VR is selected for the speed range SR represented by the above equation (1), the rotation of the coating roller 11 can be synchronized with the timing at which the sealing material 3 is separated from the coating roller 11. Then, regardless of variations in physical properties such as viscosity due to the temperature of the sealing material 3, as shown in FIG. 7A, the sealing material 3 does not separate from the outer peripheral portion 11C, maintains the thickness t1, and reaches the target region 2A. For example, it adheres to the target area 2A and separates from the coating roller 11. Therefore, the layer 3L2 of the sealing material 3 having a stable thickness is formed in the target region 2A. In this state, as shown in FIG. 7A, the amount of the sealing material 3 accumulated between the outer peripheral portion of the coating roller 11 and the outer peripheral portion of the supply roller 12 can stabilize the coating state of the sealing material 3. The minimum required amount is sufficient.

Based on the result of the test in which the roller speed _VR is changed for each temperature condition and the sealing material 3 is applied to the target area 2A by the coating system 1, the coating thickness of the sealing material 3 and the sealing material 3 apply the target area 2A. An example is a speed range in which a stable coating state is obtained from the viewpoint of the covering ratio.
Verification test results:
When the temperature is 15 ° C: 2.5 to 3 m / min When the temperature is 35 ° C: 7.5 to 14 m / min

When the sealing material 3 was applied by rolling the coating roller 11 only once from one end to the other end of the target area 2A under both the conditions of 15 ° C. and 35 ° C., the sealing material 3 was measured by the film thickness gauge. It was visually confirmed that the coating thickness (thickness of the layer 3L2) was 120 μm or more, and 100% of the target area 2A was covered with the sealing material 3.
At 35 ° C., the speed exceeding 14 m / min has not been tested due to the limitation of the upper limit speed of the moving mechanism 8. If the member 2 and the coating roller 11 are relatively moved by another moving mechanism having a higher upper limit speed than the moving mechanism 8, stable coating of the sealing material 3 is possible even if the speed exceeds 14 m / min.

When the test was conducted under the conditions of the same one-time coating as above, the temperature was 35 ° C., and the roller speed _VR was 5 m / min, the coating thickness of the sealing material 3 was insufficient. In this case, it is necessary to perform an operation such as double coating to keep the film thickness constant.
Further, when the test was conducted under the conditions that the temperature was 15 ° C. and the roller speed _VR was 10 m / min after one coating, the coating thickness of the sealing material 3 was insufficient and varied. In this case, the film thickness may not be stable even if it is applied multiple times.
From the above test results, it can be said that there is a speed range SR that contributes to the stability of the coated state of the sealing material 3 according to the temperature characteristics of the sealing material 3, so that the test results are consistent with the formula (1).

From the above test results using the coating system 1, the coating roller 11 is rotationally driven in a speed range suitable for the environmental temperature at the time of coating, so that the layer of the sealing material 3 having a stable thickness is once coated. Since 3L2 can be obtained in the target area 2A, it is possible to break away from the manual coating work and achieve automation and high speed of sealing material coating.

From the above test results, the applicable speed for each temperature is faster as the temperature of the sealing material 3 is higher. Therefore, if the coating operation is performed when the environmental temperature is relatively high, the sealing material 3 is coated while rolling the coating roller 11 on the member 2 at high speed. The time required can be shortened.
In particular, it is preferable to perform the coating operation at a temperature close to the upper limit of the temperature allowed for the sealing material 3 at the time of coating (for example, 35 ° C.) from the viewpoint of shortening the coating process.
In addition to the above, the higher the temperature of the sealing material 3, the wider the applicable speed range for each temperature. Therefore, the degree of freedom of the device for driving the coating roller 11 or the moving body 40 is high, and the coating roller 11 or the moving body 40 has a higher degree of freedom. Each can be given an appropriate speed.

(Supply mechanism)
The supply mechanism 30 (FIGS. 1 and 2) includes, for example, a container 3C, a nozzle 31, and an extrusion section 32.
The extrusion unit 32 pushes out the sealing material 3 in the container 3C from the nozzle 31 by a drive device 33 such as an air cylinder that is driven and controlled by the control unit 6. The sealing material 3 is stably supplied to the outer peripheral portion 11A of the coating roller 11 through the nozzle 31 in an amount corresponding to the coating thickness.
The extruded portion 32 moves, for example, from the position shown in FIG. 1 to the position shown in FIG. 2 as the sealing material 3 in the container 3C decreases.

The nozzle 31 located in the vicinity of the outer peripheral portion 11A gradually becomes thinner in the rolling direction D1 as it goes downward, and the opening area gradually increases in the width direction of the coating roller 11 as shown in FIG. The dimension of the lower end 31A of the nozzle 31 in the direction of the rotation axis 11B orthogonal to the rolling direction D1 is applied so that the sealing material 3 is supplied from the nozzle 31 to the entire width direction of the outer peripheral portion 11A of the coating roller 11. It is preferable that the width of the roller 11 is set to be the same as the width dimension.

(Temperature adjustment mechanism)
The temperature adjusting mechanism 7 has at least one function of heating and cooling, and adjusts the sealing material 3 to a predetermined temperature. When the sealing material 3 is heated, the temperature adjusting mechanism 7 may be provided with, for example, a heating wire or a heat source and a heat medium such as hot water or hot air. When cooling the sealing material 3, the temperature adjusting mechanism 7 may include, for example, a Pelche element. When the environmental temperature exceeds the upper limit of the allowable temperature of the sealing material 3, the temperature of the sealing material 3 can be maintained below the allowable value by the temperature adjusting mechanism 7 having a cooling mechanism.

The temperature adjusting mechanism 7 of the present embodiment includes a cover 71 that covers the container 3C, which is a supply source of the sealing material 3, and a heating wire (not shown) incorporated in the cover 71, and controls the output of the heating wire to be energized. By controlling by the unit 6, the temperature of the sealing material 3 is adjusted to, for example, 30 ° C. or higher via the container 3C. However, the temperature is controlled so as not to exceed the temperature allowed for the sealing material 3.
FIG. 1 shows a container 3C in which a part of the cover 71 is broken and covered with the cover 71. When heat is generated from the heating wire by energization, the entire range including the container 3C inside the cover 71, the extrusion portion 32, and a part of the nozzle 31 is heated as shown by the dot-shaped pattern in FIG. To.
The temperature adjusting mechanism 7 can be appropriately configured according to the configuration of the supply mechanism 30. Other examples will be described later (FIG. 8).

The nozzle 31 and the coating roller 11 so that the temperature given to the sealing material 3 by being heated or cooled by the temperature adjusting mechanism 7 is maintained as much as possible until the sealing material 3 reaches the target area 2A. All or part of the supply roller 12 can be formed of a resin material or the like having a lower thermal conductivity than that of a metal material. Examples of the resin material that can be adopted include silicone resin.
In addition to heat retention, it is also possible to incorporate the temperature adjusting mechanism 7 into the coating roller 11 and the supply roller 12.

When the sealing material 3 is adjusted to a constant temperature by the temperature adjusting mechanism 7, the speed range SR of the coating roller 11 that can obtain a stable coating state of the sealing material 3 is determined as described by showing the equation (1). ..
When the temperature adjusting mechanism 7 is provided, the relationship between the temperature of the sealing material 3 and the speed range SR can be established regardless of the environmental temperature. For example, the sealing material 3 can be provided with a temperature suitable for a speed range in which the coating roller 11 and the moving body 40 can be driven by the driving device.

(Moving bodies, coating rollers, and supply rollers)
The moving body 40 is moved with respect to the member 2 by the moving mechanism 8 (FIG. 2) along the rolling direction D1 in which the coating roller 11 rolls. FIG. 2 shows only the mounting portion 81 of the moving mechanism 8 to which the moving body 40 is detachably mounted, and the entire moving mechanism 8 provided with a rail or the like capable of guiding the mounting portion 81 in the horizontal direction or the vertical direction. Illustration is omitted.
When the moving body 40 is moved by the moving mechanism 8 with respect to the member 2 positioned at a predetermined position, the member 2 and the coating roller 11 are relatively moved at the coating speed _VA corresponding to the roller speed _VR . .. The roller speed VR and the coating speed VA are basically synchronized.

The moving body 40 includes a coating roller 11, a supply roller 12, a support portion 400 for supporting the coating roller 11, the supply roller 12, and the like, a pressurizing mechanism 41 including a spring 411 as an elastic body, and a shape parameter acquisition portion 42. And a follow-up mechanism 43.

The coating roller 11 is rotatably supported by the support portion 400 around the rotation shaft 11B, and is rotationally driven by the motor 11M (FIG. 2) under the control of the control portion 6.
The coating roller 11 is rotationally driven in the direction of the arrow _R1 at the roller speed VR, so that the coating roller 11 moves in a predetermined direction (D1) while rotating around the rotation shaft 11B while in contact with the target region 2A. The "rolling" of the coating roller 11 is used in this sense.

The coating roller 11 is formed of an appropriate material such as a resin material. The same applies to the supply roller 12.

As shown in FIGS. 6A and 6B, when the member 2 has a target area 2A long in a predetermined direction, the coating roller 11 of the moving body 40 rolls the target area 2A and targets along the longitudinal direction of the member 2. Roll region 2A. At this time, the rolling direction D1 of the coating roller 11 substantially coincides with the longitudinal direction of the member 2.

It is preferable that the coating roller 11 is provided with a width equivalent to that of the target area 2A. In order to reliably apply the sealing material 3 over the entire target area 2A, the width of the coating roller 11 can be set to be several mm larger than the width of the target area 2A, for example.
When the width of the coating roller 11 and the width of the target area 2A are the same, it is possible to prevent the sealing material 3 from dripping from both sides in the width direction of the coating roller 11, so that the accumulated sealing material 3 is the target area 2A. It may affect the thickness of the sealing material 3 at both ends in the width direction, or may cause contamination in which the sealing material 3 discharged earlier from the nozzle 31 is mixed with the sealing material 3 discharged after that. Can be avoided.
Moreover, the coating of the sealing material 3 over the entire target area 2A can be completed by one coating step of rolling the coating roller 11 from one end to the other end of the long target area 2A.

The coating system 1 can also be applied to a target area 2A having a width wider than the width of the coating roller 11. In this case, the sealing material 3 can be applied over the entire target area 2A while the moving body 40 is moved by the moving mechanism 8 in the width direction of the target area 2A.

The supply roller 12 is adjacent to the front of the coating roller 11 and is supported by the support portion 400. A stable supply amount is supplied from above the supply roller 12 and the coating roller 11 to the outer peripheral portion 11A of the coating roller 11. The supplied sealing material 3 accumulates between the supply roller 12 and the coating roller 11 and is rotationally driven in opposite directions to the outer peripheral portion 11C of the coating roller 11 through the gap 13 between the supply roller 12 and the coating roller 11. The sealing material 3 is supplied in a stable supply amount. As a result, the thickness of the sealing material 3 on the outer peripheral portion 11C can be made more stable, so that the thickness of the layer 3L2 of the sealing material 3 formed on the target region 2A by the transfer from the coating roller 11 can be made more stable. Can be made to. The gap 13 functions as a nozzle for supplying the sealing material 3 to the outer peripheral portion 11C of the coating roller 11.

The supply roller 12 is directed to the rotation axis 11B of the coating roller 11 by the motor 12M (FIG. 2) under the control of the control unit 6 in the direction (R2) opposite to the rotation direction (R1) of the coating roller 11. It is rotationally driven around the parallel rotation axis 12B.
The supply roller 12 does not come into contact with the target area 2A when the target area 2A is applied by the coating roller 11. The peripheral speed of the supply roller 12 may be basically the same as the roller speed _VR . The diameter of the supply roller 12 can be appropriately determined as long as it does not interfere with the target area 2A, the support portion 400, or the like.
In order to stably supply the sealing material 3 over the entire width direction of the outer peripheral portion 11C, it is preferable that the width of the supply roller 12 is set to be the same as the width of the coating roller 11.

It is preferable that the supply roller 12 is provided with circular partitions 121 (FIG. 1) on both sides in the axial direction. The pair of partitions 121 are rotated around the rotation shaft 12B together with the supply roller 12. The pair of partitions 121 are provided on the bush 122 that attaches the supply roller 12 to the support portion 400, and have a diameter larger than that of the outer peripheral portion 12A, so that the pair of partitions 121 project from the outer peripheral portion 12A over the entire circumference. Therefore, the sealing material 3 accumulated in the section between the pair of partitions 121 is separated from the outside of the partition 121, so that dust and the like from the outside are prevented from being mixed into the sealing material 3 and the pair of partitions 121 Since the area to which the sealing material 3 adheres is limited between them, the area to which the sealing material 3 adheres can be easily washed.
The pair of partitions 121 do not necessarily have to rotate together with the supply roller 12.

(Support, pressurization mechanism, and follow-up mechanism)
The support portion 400, the pressurizing mechanism 41, the shape parameter acquisition portion 42, and the follow-up mechanism 43 will be briefly described.
The support portion 400 supports the coating roller 11, the supply roller 12, the supply mechanism 30, and the temperature adjusting mechanism 7. The support portion 400 includes a laminate including a first support plate 401, a second support plate 402, and a third support plate 403, a support column 404 that supports the container 3C and the drive device 33, and a mounting portion 81 of the moving mechanism 8. It is provided with a mounting portion 405 to be mounted on the.

(Pressurization mechanism)
The pressurizing mechanism 41 has a coil spring 411 as a plurality of (here, four) elastic bodies that support the second support plate 402 above the first support plate 401 that supports the coating roller 11, the supply roller 12, and the like. Have. The height of the mounting portion 81 that supports the support portion 400 with respect to the target region 2A is increased by the moving mechanism 8 so that the coating roller 11 comes into contact with the state of being pressed against the target region 2A by the elastic force of these coil springs 411. At the same time, the elastic force of the coil spring 411 is adjusted by a plurality of (here, four) expansion / contraction portions 431.

Unlike the present embodiment, the device that supports the member 2 may be provided with a pressurizing mechanism that presses the coating roller 11 and the member 2 into contact with each other.

(Shape parameter acquisition unit)
The shape parameter acquisition unit 42 is a line sensor that scans the target region 2A in the width direction using, for example, a laser. The shape parameter acquisition unit 42 detects a shape parameter indicating the shape of the target region 2A in front of the coating roller 11 while moving in the rolling direction D1 together with the support unit 400, for example, provided on the first support plate 401. The shape parameter is, for example, a vector of normals orthogonal to the surface of the target region 2A. When the shape of the target region 2A changes in the rolling direction D1, the detected normal vector changes.

The shape parameter acquisition unit 42 is not limited to the line sensor, and may include, for example, a camera that captures the target area 2A and an image processing unit that acquires shape parameters from the image data obtained by the camera. .. Illustration of the camera and image processing unit is omitted.

(Following mechanism)
The follow-up mechanism 43 uses the shape parameter (normal vector) acquired by the shape parameter acquisition unit 42 to follow the posture of the coating roller 11 with respect to the shape change of the target region 2A. The pressurizing mechanism 41 having the coil spring 411 described above allows the coating roller 11 to follow the inclination of the target region 2A to some extent. According to the follow-up mechanism 43, the coating roller 11 can follow a large inclination exceeding the follow-up range of the pressurizing mechanism 41.
The follow-up mechanism 43 includes a telescopic portion 431 made of a plurality of expandable air cylinders and the like provided between the second support plate 402 and the third support plate 403, and a swing mechanism 432 in the width direction of the target region 2A. Has.

Each of the pair of swing mechanisms 432 includes a motor 432B that drives the first support plate 401 with respect to the second support plate 402 centered on the shaft portion 432A. The swing mechanism 432 is arranged on the front side and the rear side in the rolling direction D1 of the moving body 40, respectively.
For example, assuming that the member 2 is inclined with respect to the horizontal plane, the motor 432B is driven by the control unit 6 to be supported by the first support plate 401 and the first support plate 401 as shown in FIG. The rollers 11 and 12 and the container 3C can be swung in the width direction of the target region 2A with respect to the second support plate 402 and the third support plate 403.

The control unit 6 grasps a shape change such as an inclination of the target area 2A by monitoring a shape parameter such as a normal vector, and drives each expansion / contraction unit 431 and each swing mechanism 432 so as to follow the shape change. By doing so, the posture of the coating roller 11 is changed. By providing the moving body 40 with such a following mechanism 43, it is possible to increase the angle capable of following the shape change of the target region 2A as compared with the case where the coating roller 11 is provided with the following mechanism, for example.
According to the attitude control using the shape parameter acquisition unit 42 and the follow-up mechanism 43, the shapes of a large number of members 2 given various shapes, such as the members 2 constituting the airframe of an aircraft, can be changed to the dimensional shape tolerance. Including, while continuously grasping during coating, the sealing material 3 does not cause the coating roller 11 to slip in the width direction with respect to the target area 2A or to separate from the target area 2A, and to apply appropriate contact pressure. The sealing material 3 can be stably applied while being applied to the application roller 11 and the member 2.

It is preferable to suppress the angle formed by the outer peripheral surface of the coating roller 11 with respect to the target region 2A to, for example, 5 ° or less by posture control using the follow-up mechanism 43. The angle can also be expressed by the angle formed by the normal vector of the target region 2A and the central axis X set in the moving body 40 (for example, θ in FIG. 6).
When the same test as the above-mentioned verification test was performed on the target area 2A inclined with respect to the horizontal plane, the sealing material 3 was applied over the entire surface of the target area 2A with a sufficient coating thickness when the temperature was 5 ° or less. It was confirmed that.

An elastic body such as a spring 411 is not always necessary in order to press the coating roller 12 and the member 2 into contact with each other. For example, the coating roller 12 and the target area 2A of the member 2 are displaced by vertically displacing the support 400 by the moving mechanism 8 while detecting the load applied to the mounting portion 81 that supports the support portion 400 by the sensor. It may be pressed with a predetermined force. In this case, the pressurizing mechanism 41 is not required.
Further, if the posture of the support 400 is controlled by the moving mechanism 8, the moving mechanism 8 also has the function of the pressurizing mechanism 41 and the function of the following mechanism 43, so that the pressurizing mechanism 41 and the following mechanism 43 are required. Do not.

[Seal material application method]
An example of the procedure for applying the sealing material 3 by the coating system 1 described above will be described.
If the roller speed V _R is acquired from the speed range SR based on the above equation (1) (roller speed acquisition step), the moving body 40 is moved by the moving mechanism 8 at a coating speed V _A synchronized with the roller speed V _R. While feeding the target region 2A in the rolling direction D1 and supplying the sealing material 3 from the nozzle 31 to the coating roller 11 by the supply mechanism 30, under the drive control by the control unit 6, the coating roller 11 moves in the R1 direction. While controlling the roller speed VR, the rotation speed of the supply roller 12 in the _R2 direction is controlled to a speed synchronized with the roller speed _VR , and the coating roller 11 is pressed against the target area 2A by the pressurizing mechanism 41. The sealing material 3 is applied to the target area 2A by the application roller 11 (application step). It is preferable to correct the posture of the coating roller 11 or the like by using the shape parameter detected by the shape parameter acquisition unit 42 in this coating step.
It is preferable to adjust the temperature of the sealing material 3 by the temperature adjusting mechanism 7 prior to the coating step or in parallel with the coating step.
As described above, the coating roller 11 is rotationally driven at the roller speed _VR determined in the speed range SR corresponding to the temperature characteristic of the sealing material 3, so that the coating roller 11 can be sealed even if it is coated once. The material 3 can be applied to the target area 2A to a desired thickness. According to the present embodiment, as shown in the above test results, it is possible to realize a coating speed _VA that greatly exceeds the speed of manual coating work.

By using the supply roller 12 in addition to the coating roller 11 as in the present embodiment, the target area is the layer 3L2 having a stable thickness due to the sealing material 3 supplied to the target area 2A through the gap 13 between the two. It can be formed in 2A. Further, as described above, since the sealing material 3 stays between the coating roller 11 and the supply roller 12 in the minimum necessary amount, foreign matter or the like may be mixed into the sealing material 3 or discharged from the nozzle 31. It is possible to avoid mixing the sealing materials 3 having different elapsed times as much as possible, and it is possible to easily perform the cleaning work of removing the sealing materials 3 from the rollers 11 and 12.

In addition to the above, it is possible to select the configuration described in the above embodiment or change it to another configuration as appropriate.
As shown in FIG. 8, which is a modification of the present embodiment, the supply mechanism 30 of the sealing material 3 has a tank 301 as a supply source, a nozzle 31 for discharging the sealing material 3 to the coating roller 11, a tank 301, and a nozzle. A hose 302 connecting the 31 may be provided. In this case, the tank 301 and the hose 302 may be covered with the heating covers 701 and 702 as the temperature adjusting mechanism 7. For example, a heating wire can be incorporated in the heating covers 701 and 702.
Also in this modification, the nozzle 31 is driven while the coating roller 11 is rotationally driven at the roller speed _VR and the moving body 40 is sent to the target area 2A at the coating speed _VA synchronized with the roller speed _VR . By applying the sealing material 3 supplied to the coating roller 11 to the target area 2A, a stable coating thickness can be realized even once on the target area 2A, so that the sealing material application can be automated and speeded up. can.
