Description

The present disclosure relates to a system and a method 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.
The coating work of the sealing material using a roller is performed by hand while checking the state such as the thickness of the layer formed by the sealing material on the joint surface.

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 is a pressure contact between 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 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.

Since it is difficult to stabilize the coating state of the sealing material by the coating device, it is difficult to put into practical use a coating device that automates the coating process of the sealing material, and the coating process of the sealing material is still relied on manually.
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 state 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, it is an object of the present disclosure to provide a system and a method capable of practical application of a coating system by realizing stable coating of a non-Newtonian fluid such as a sealing material.

The non-Newtonian fluid coating system of the present disclosure includes a coating roller that is rotationally driven and rolls in a target area of a target member, a supply mechanism that supplies non-Newtonian fluid to the outer peripheral portion of the coating roller, and a direction in which the coating roller rolls. In front of the coating roller in the above, a supply roller arranged with a gap between the coating roller and the coating roller is provided. The supply roller is rotationally driven in the direction opposite to the direction of rotation of the coating roller. The non-Newtonian fluid is applied from the application roller to the target area while the target member and the application roller are relatively moved by the moving mechanism.

Further, the present disclosure is a method of applying a non-Newtonian fluid to a target area by using a coating roller that rolls the target area of the target member, and the non-Newtonian fluid coating system including the coating roller is used to apply the non-Newtonian fluid to the target area. In front of the coating roller in the direction in which the roller rolls, the supply roller arranged with a gap between the roller and the coating roller is rotationally driven in the opposite direction, and the target member and the coating roller are relatively moved. A coating step is provided in which the non-Newtonian fluid is applied from the coating roller to the target area while supplying the non-Newtonian fluid to the outer peripheral portion of the coating roller.

According to the present disclosure, in addition to the coating roller, a supply roller that is rotationally driven in the direction opposite to the coating roller is used, so that a non-Newtonian fluid having a stable thickness is used through a gap between the coating roller and the supply roller. A layer composed of can be formed in the target region. By stabilizing the application state of the non-Newtonian fluid, it is possible to realize automation and speeding up of application of the non-Newtonian fluid.

Hereinafter, embodiments will be described with reference to the accompanying drawings. The embodiments described below disclose a system and a method for applying the sealing material 3 to the member 2 by using the coating roller 11.

[First Embodiment]
According to the sealing material coating system 1 (FIGS. 1 to 3) of the present embodiment, 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. 7A or the frame 2-2 shown in FIG. 7B. 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 contains an appropriate dispersoid selected from the viewpoint of weather resistance and the like, and a dispersion medium, and is applied to the target region 2A of the member 2 in a state of having 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.

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 coating roller 11 that rolls the target area 2A of the member 2 is used, and the member 2 and the coating roller 11 are moved by the moving mechanism 8. The sealing material 3 is applied from the application roller 11 to the target area 2A while being relatively moved.
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 RD) 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. A moving body 40 including the coating roller 11 and the supply roller 12 and a control unit 6 for controlling the rotational drive of the coating roller 11 and the supply roller 12 are provided.
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, the coating system 1 includes a pressurizing mechanism 41 that brings the coating roller 11 and the target region 2A into contact with each other by an elastic force, a shape parameter acquisition unit 42 for making the coating roller 11 follow the shape change of the member 2, and a tracking mechanism. It is preferable to have 43. The pressurizing mechanism 41, the shape parameter acquisition unit 42, and the following mechanism 43 can be provided on the moving body 40 as in the present embodiment.

(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 RD 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 RD 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.

(Mobile)
The moving body 40 is moved with respect to the member 2 by the moving mechanism 8 (FIG. 2) along the rolling direction RD 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.
The moving body 40 is moved by the moving mechanism 8 with respect to the member 2 positioned at a predetermined position.

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.

(Applying roller)
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 to move in a predetermined direction (RD) 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 will be described later, it is preferable that the control unit 6 synchronizes both the rotation speed of the coating roller 11 and the rotation speed of the supply roller 12 with respect to the relative moving speed between the member 2 and the coating roller 11. When controlling the respective speeds of the coating roller 11 and the supply roller 12, a servomotor is used for the motors 11M and 12M.

As shown in FIGS. 7A and 7B, 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 along the longitudinal direction of the member 2. At this time, the rolling direction RD 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.

It is preferable that the coating roller 11 has a diameter of a certain value or more in consideration of the stability of the coating state of the sealing material 3 and the increase in the coating speed determined by the rotation speed and the diameter of the coating roller 11. If the coating roller 11 has a diameter equal to or larger than a certain diameter, the coating state of the sealing material 3 can be stabilized by securing a portion where the coating roller 11 contacts the target region 2A over a certain region or more. Further, the coating speed can be increased while keeping the rotation speed of the motor 11M within the upper limit.
The diameter of the coating roller 11 is preferably, for example, 30 mm or more.
As with the supply roller 12, it is preferable that the supply roller 12 synchronized with the rotation of the coating roller 11 also has a diameter equal to or larger than a certain value in consideration of increasing the coating speed. The diameters of the coating roller 11 and the supply roller 12 do not have to be the same and may be different.

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.

(Supply roller)
The supply roller 12 is adjacent to the front of the coating roller 11 and is supported by the support portion 400. The sealing material 3 supplied from above the supply roller 12 and the coating roller 11 to the outer peripheral portion 11A of the coating roller 11 is supplied by being rotationally driven in opposite directions while accumulating between the supply roller 12 and the coating roller 11. Through the gap 13 between the roller 12 and the coating roller 11, the coating roller 11 is supplied with a stable supply amount to the outer peripheral portion 11C below the gap 13. 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.

In order to stably supply the sealing material 3 over the entire width direction of the outer peripheral portion 11C, the width of the supply roller 12 is preferably the same as or substantially the same as the width of the coating roller 11. The width of the supply roller 12 is too wide to be wider than the width of the coating roller 11, and the sealing material 3 accumulates on both sides of the supply roller 12, and the accumulated sealing material 3 affects the thickness of the sealing material 3 on both sides of the coating roller 11 in the width direction. In order to avoid this, even if the width of the supply roller 12 is wide, it is preferable to keep the difference in width between the rollers 11 and 12 to a few mm.

As shown in FIG. 5A, the sealing material 3 supplied from the nozzle 31 of the supply mechanism 30 to the outer peripheral portion 11A of the coating roller 11 creates a gap 13 between the rollers 11 and 12 as the coating roller 11 and the supply roller 12 rotate. It passes through and forms a layer 3L1 having a thickness corresponding to the dimension of the gap 13 over the entire width direction of the outer peripheral portion 11C.
The outer peripheral portion 11C corresponds to the range from the position of the gap 13 to the target region 2A in the rotating coating roller 11. The outer peripheral portion 11A is located above the gap 13.

Even if the supply amount of the sealing material 3 from the nozzle 31 per unit time fluctuates, the sealing material 3 accumulates between the rollers 11 and 12, and as the rollers 11 and 12 rotate, the sealing material 3 passes through the gap 13 in the width direction toward the outer peripheral portion 11C. Since it is supplied at a uniform flow rate over the entire area, the thickness of the sealing material 3 on the outer peripheral portion 11C is stable. Therefore, the thickness t of the layer 3L2 of the sealing material 3 formed on the target region 2A by the transfer from the outer peripheral portion 11C can be stabilized.

The amount of the sealing material 3 accumulated between the coating roller 11 and the supply roller 12 is sufficient to be the minimum necessary amount capable of stabilizing the coating state of the sealing material 3.

As shown in the comparative example of FIG. 5B, when the plate 14 is installed at a predetermined position in front of the coating roller 11 instead of the supply roller 12, the sealing material 3 stays in the plate 14 from above the gap 15. Since the behavior of the sealing material 3 moving to the outer peripheral portion 11C is not stable, the thickness of the sealing material 3 is not stable in both the outer peripheral portion 11C and the target region 2A.

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. Since the partition 121 has a larger diameter than the outer peripheral portion 12A, the partition 121 projects 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.

(Control unit)
In order to make the thickness of the sealing material 3 applied to the target area 2A more stable, the control unit 6 has either the coating roller 11 or the supply roller 12 with respect to the relative moving speed F between the member 2 and the coating roller 11. It is preferable to synchronize the rotation of.
Here, the moving speed F, the thickness t of the sealing material 3 required for the target area 2A, the supply amount c (flow rate) of the sealing material 3 from the supply mechanism 30 to the coating roller 11, and the width of the coating roller 11. It has the relationship of the following equation (1) with W ₁ .

α is a coefficient for correcting the supply amount c. For example, in order to prevent the thickness of the sealing material 3 in the target area 2A from becoming insufficient due to the sealing material 3 adhering to the outer peripheral portion 12A of the supply roller 12, the partition 121, etc., α is set to a value exceeding 1. good. It is also possible to adjust the supply amount c by changing α while applying the sealing material 3 from the coating roller 11 to the target area 2A.

In the control unit 6, the sealing material 3 is accumulated between the coating roller 11 and the supply roller 12 while the sealing material 3 is applied to the target area 2A, and the sealing material 3 passes through the outer peripheral portion 11C through the gap 13. The discharge flow rate of the sealing material 3 from the nozzle 31 can be controlled constantly or variably so as to be supplied to the target region 2A.
An appropriate amount of the sealing material 3 may be supplied in advance between the coating roller 11 and the supply roller 12 before coating.

The control unit 6 or another control unit (not shown) drives the movement mechanism 8 at the movement speed F to send the moving body 40 including the coating roller 11 to the member 2 in the rolling direction RD.
At this time, in order to make the thickness of the sealing material 3 more stable, it is preferable to match the moving speed F with the peripheral speed of the coating roller 11. Further, for the same reason, it is preferable to match the peripheral speed of the coating roller 11 with the peripheral speed of the supply roller 12. The rotation speeds s ₁ and s ₂ are determined from the moving speeds F and the diameters D ₁ and D ₂ of the rollers 11 and 12, respectively.

Assuming that the diameter of the coating roller 11 is D ₁ and the diameter of the supply roller 12 is D ₂ , the control unit 6 derives the rotation speed s1 of the coating roller 11 from the following equation (2), and derives the following equation. The rotation speed s ₂ of the supply roller 12 can be derived from (3), and the rotation speeds s ₁ and s ₂ can be used for synchronous control of the rollers 11 and 12.

An example of each of the set value and the control parameter set in the control unit 6 is shown. The control unit 6 can store the following set values and control parameters in the storage medium, read them out from the storage medium, and use them for controlling the supply mechanism 30, the coating roller 11, and the like.
<Set value>
Required thickness: t [mm]
Movement speed: F [mm / min]
Diameter of coating roller 11: D ₁ [mm]
Width of coating roller 11: W ₁ [mm]
Diameter of supply roller 12: D ₂ [mm]

<Control parameters>
Supply amount of sealing material 3: c [mm ³ / min]
Rotation speed of coating roller 11: s ₁ [min ^-1 ]
Rotation speed of supply roller 12: s ₂ [min ^-1 ]

When the moving speed F and the peripheral speed obtained from the rotation speed s ₁ and the diameter D ₁ match or substantially match, the rotation of the coating roller 11 is synchronized with the moving speed F. Similarly, when the moving speed F and the peripheral speed obtained from the rotation speed s ₂ and the diameter D ₂ match or substantially match, the rotation of the supply roller 12 is synchronized with the moving speed F. If the rotations of the coating roller 11 and the supply roller 12 are synchronized with the moving speed F, the rotations of the rollers 11 and 12 are also synchronized with each other.

When the rotation of the coating roller 11 and the rotation of the supply roller 12 are synchronized, the flow of the sealing material 3 through the gap 13 is stabilized, so that the thickness of the layer 3L1 of the sealing material 3 in the outer peripheral portion 11C is also stable.
Further, when the rotation of the coating roller 11 is synchronized with the moving speed F, the coating roller 11 rolls on the target area 2A without slipping, so that the layer 3L1 of the sealing material 3 is stably peeled off from the coating roller 11. As a result of being transferred to the target region 2A, the thickness of the layer 3L2 of the sealing material 3 in the target region 2A can be more sufficiently stabilized.

(Support part)
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 brings the coating roller 11 and the member 2 into contact with each other by an elastic force.

(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 RD 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. FIG. 8 shows an image of the normal vector of the target area 2A that can be detected by the line sensor by a plurality of arrows. When the shape of the target region 2A changes in the rolling direction RD, the detected normal vector changes. As shown by the normal vector in FIG. 8, the inclination of the target region 2A in the width direction is not always constant.

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 RD 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 tracking 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).

An elastic body such as a spring 411 is not always necessary in order to press the coating roller 11 and the member 2 into contact with each other. For example, the coating roller 11 and the target area 2A of the member 2 are displaced by vertically displacing the support portion 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 portion 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.
Based on the above equations (1) to (3), the control unit 6 acquires the supply amount c of the sealing material 3, the rotation speed s ₁ of the coating roller 11, and the rotation speed s ₂ of the supply roller 12 through calculations. If so (control parameter acquisition step), the moving mechanism 8 sends the moving body 40 to the target region 2A in the rolling direction RD at the moving speed F, and the supply mechanism 30 feeds the moving body 40 from the nozzle 31 at the supply amount c. While supplying the sealing material 3 to the coating roller 11, the rotation of the coating roller 11 in the _R1 direction is controlled to the rotation speed s1 and the rotation of the supply roller 12 in the R2 direction is rotated under the drive control by the control unit 6. The number s ₂ is controlled, and the sealing material 3 is applied to the target area 2A by the coating roller 11 while the coating roller 11 is pressed against the target area 2A by the pressurizing mechanism 41 (application step). It is preferable to correct the postures of the coating roller 11 and the supply roller 12 by using the shape parameter detected by the shape parameter acquisition unit 42 in this coating step.

The moving speed F of the moving body 40 with respect to the member 2 can be variably controlled by the control unit 6 or another control unit. For example, in order to avoid insufficient thickness of the sealing material 3 in the step 2S of the member 2 (FIG. 5A), in front of the step 2S in the target region 2A based on the shape parameters acquired before or during the coating. By decelerating the moving body 40, the amount of the sealing material supplied from the coating roller 11 to the target area 2A per unit length is increased, and the speed of the moving body 40 is returned to the moving speed F after passing through the step 2S. You may. The rotation speed s ₁ of the coating roller 11 and the rotation speed s ₂ of the supply roller 12 may be adjusted so as to follow the shift of the moving body 40.

According to the present embodiment, by using the supply roller 12 in addition to the coating roller 11, 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 is targeted. It can be formed in the region 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.
By using the coating system 1 including the coating roller 11 and the supply roller 12, it is possible to get rid of the manual coating work and realize automation and high speed of sealing material coating.

[Second Embodiment]
A second embodiment will be described with reference to FIGS. 9, 10 and 11A.
Hereinafter, matters different from those of the first embodiment will be mainly described. The same components as those in the first embodiment are designated by the same reference numerals.
As shown in FIGS. 9 and 10, the coating system 1-2 of the second embodiment includes a temperature adjusting mechanism 7 that adjusts the sealing material 3 to a predetermined temperature. According to the coating system 1-2 and the sealing material coating method according to the second embodiment, a layer of the sealing material 3 having a desired thickness is formed in the target area 2A even if it is applied once.

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 second embodiment, the roller speed _VR at the time of coating is derived 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. Thereby, the state of application of the sealing material 3 to the target area 2A can be stabilized and the bonding quality between the members can be improved.

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 s ₁ of the coating roller 11, the diameter D ₁ , and the pi, the rotation speed s ₁ as the roller speed corresponding to the temperature characteristic of the sealing material 3 is acquired and rotated. The number s ₁ may be used to convert to the peripheral speed of the coating roller 11.

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 (4). ..
_VG < _VR < _VS (4)
_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 a coating test is performed at different roller speeds _VR , the relationship between _VG and _VR is reversed from that of equation (4), and the relationship between _VR and _VS is that of equation (4). If it is reversed, it will be difficult to stabilize the coating state.

From the above equation (4), 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 in the roller speed _VR .

FIG. 11A 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 .
When the relationship of the above formula (4) holds, as shown in FIG. 11A, 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 (4) does not hold will be described with reference to FIGS. 11B and 11C. When the formula (4) 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, the sealing material 3 has variations in physical properties such as viscosity depending on the temperature of the sealing material 3. It is difficult to stabilize the coating state of the sealing material 3 because the influence on the flow state of the sealing material 3 is large.

As shown in FIG. 11B, when _VR is sufficiently smaller than _VG ( _VR << _VG ), the roller speed _VR is slower than that in FIG. 11A, 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. _11C , when _VR is sufficiently larger than VS (VS _{<< VR} ), the roller speed _VR is faster than that in FIG. 11A, 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. 11C. 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 (4), 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. 11A, 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.

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 1-2, the coating thickness of the sealing material 3 and the sealing material 3 are the target areas. An example is a speed range in which a stable coating state is obtained from the viewpoint of the ratio of covering 2A.
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.

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 (4).

From the above test results using the coating system 1-2, the sealing material 3 with a stable thickness is once coated by rotationally driving the coating roller 11 in a speed range suitable for the environmental temperature at the time of coating. Layer 3L2 can be obtained in the target region 2A.

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.

When the same test as the above-mentioned verification test was performed on the target area 2A at 5 ° 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. Was confirmed.

(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.
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. Although not shown, for example, even if the supply mechanism of the sealing material 3 includes a tank as a supply source, a nozzle for discharging the sealing material 3 to the coating roller 11, and a hose connecting the tank and the nozzle. good. In this case, the tank and the hose may be covered with a heating cover as the temperature adjusting mechanism 7. For example, a heating wire can be incorporated in the heating cover.

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 (4). ..
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.

[Seal material application method]
An example of the procedure for applying the sealing material 3 by the application system 1-2 will be described.
The roller speed VR is set from the speed range SR based on the above formula (4), and the supply amount c of the sealing material 3 and the roller speed _V are set by the control unit 6 based on the above formulas (1) to (3). The rotation speeds s ₁ and s ₂ of the coating roller 11 and the supply roller 12 converted from _R are obtained, respectively.
Then, as in the first embodiment, the moving mechanism 8 sends the moving body 40 to the target region 2A in the rolling direction RD at the moving speed F, and the supply mechanism 30 supplies the amount c from the nozzle 31. While supplying the sealing material 3 to the coating roller 11, the rotation speed of the coating roller 11 in the _R1 direction is controlled to s1 under the drive control by the control unit 6, and the rotation speed of the supply roller 12 in the R2 direction. Is controlled to s2, and the sealing material ₃ is applied to the target area 2A by the application roller 11 (application step). During the coating step, the coating roller 11 may be pressed against the target area 2A by the pressurizing mechanism 41, and the posture of the coating roller 11 or the like may be corrected by using the shape parameter detected by the shape parameter acquisition unit 42. ..
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.

According to the present embodiment, the coating roller 11 is rotationally driven at the roller speed _VR determined in the speed range SR corresponding to the temperature characteristics of the sealing material 3, so that the sealing material 3 can be coated even once. It 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 that greatly exceeds the speed of manual coating work.

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.
For example, the coating system 1 of the first embodiment may include a temperature adjusting mechanism 7 for adjusting the sealing material 3 to a predetermined temperature. In that case, the supply mechanism 30, the movement mechanism 8, and the rollers 11 and 12 can be controlled for the movement speed F, the supply amount c, and the rotation speeds s ₁ and s ₂ according to the temperature of the sealing material 3.
