By the way, in the case of manual coating, it is necessary for the operator himself to recognize the uncoated portion during the operation so that the uncoated portion does not occur. However, this recognition may not always be easy.
The application of the coating agent is to protect the surface of the solar panel. However, when an uncoated portion is formed, the dirt adheres and the protection of the solar panel becomes insufficient. Further, if there is a portion where dirt is likely to adhere, the dirt tends to spread throughout the solar panel starting from the portion where the dirt is attached. If the surface of the solar panel tends to get dirty, the power generation efficiency tends to decrease.

Each tube 77b is inserted into a hole (not shown) formed in a hard sponge portion 71b to 74b described later, and the application liquid is applied to the application side sponge portions 71c to 74c described later through the hole. It can be supplied.

  As shown in FIG. 3, one application unit 70 includes a plurality (four in this embodiment) of pads 71 to 74 and pad support units 81 to 84 that are individually installed for each pad. And. The plurality of pads 71 to 74 are arranged in series in a state extending in the longitudinal direction Y (vertical direction) of the frame body 11.

  Each of the pads 71 to 74 includes a core part 71a to 74a made of sponge (see FIG. 6 and FIG. 7 for the pad 71). Engineering member) 75 is wound. Further, the application unit 70 includes an integral outer cloth portion (coating member) 76 wound around the outside of all the pads arranged in series.

The core portions 71a to 74a are generally rectangular in shape, and are hard sponge portions 71b to 74b disposed on the second support portions 81b to 84b described later, and a rectangular parallelepiped shape disposed on the panel surface s side. Application side sponge portions 71c to 74c. Both sponge parts are made of an elastic sponge, and the application-side sponge parts 71c to 74c are made of a sponge that can be impregnated with an application liquid. As each sponge, an appropriate sponge such as one made of melamine resin can be used.
The inner cloth portion 75 is disposed outside the core portions 71a to 74a so as to cover the core portions 71a to 74a, and when the pads 71 to 74 are positioned at the application position (see FIG. 5), the outer cloth portion It is in contact with the panel surface s via 76.
The outer cloth portion 76 is disposed outside the inner cloth portion 75 (outside the core portions 71a to 74a), and comes into contact with the panel surface s when the pads 71 to 74 are positioned at the application position (see FIG. 5). Is.
As will be described later, only one of the inner cloth portion 75 and the outer cloth portion 76 may be used (see FIG. 8).

  Each pad support part 81-84 is attached to the mobile body 40a. As shown in FIG. 6, the first support parts 81a-84a attached to the mobile body 40a so as to be swingable. Second support portions 81b to 84b fixed in a rotatable state to the tip portions of the first support portions 81a to 84a, and pads 71 to 74 corresponding to the tip portions of the second support portions 81b to 84b. It is attached.

Each of the first support portions 81a to 84a can swing around a rotation axis Ya extending in the frame body longitudinal direction Y with respect to the movable body main body 40a, and each of the second support portions 81b to 84b is all The first support portions 81a to 84a can rotate around the rotation axis Yb in the frame body longitudinal direction Y.
The application unit 60 includes a swing mechanism 85 (see FIG. 5) that swings the first support portions 81a to 84a. By actuating the swing mechanism 85, the application portion 70 is separated from the application position (see FIG. 5A) where the pads 71 to 74 are in contact with the panel surface s, and the pads 71 to 74 are separated from the panel surface s. To the retracted position (see FIG. 5B).

  The second support portions 81b to 84b are fixed to the first support portions 81a to 84a by bolts B and nuts N (see FIG. 6). Therefore, it can fix in the state located in the appropriate rotation position with respect to the 1st support parts 81a-84a.

  The swing mechanism 85 is only shown in FIG. 5 for the sake of convenience in order to clearly show the configuration of the coating unit 60, and is not shown in other drawings. Various swinging mechanisms 85 can be used. Here, the connecting rod 85a is connected to all the first support portions 81a to 84a, and the tip of the telescopic rod 85b is connected to the connecting rod 85a. Is a well-known mechanism that swings using a connected air cylinder 85c (see FIG. 10), and the description thereof is omitted. Further, the coating apparatus of the present embodiment includes a controller 99 (see FIG. 10) that controls the operation of the traveling motor 25, the vertical movement motor 45, the coating liquid supply pump 79, the air cylinder 85c of the swing mechanism 85, and the like. However, since the controller has a known configuration, the description thereof is omitted here.

  By the way, when each pad 71-74 of the application part 70 is located in a contact position, the edge part (the corner | angular part of a pad shown by Fig.5 (a)) located in the front end side (panel surface side) of a pad 70a comes into contact with the panel surface. When the coating liquid is applied to the panel surface with the pad in this state, the coating quality is stabilized, for example, the thickness of the coating film formed on the pad surface becomes more stable.

The pads 71 to 74 are supported so as to be swingable with respect to the second support portions 81b to 84b of the pad support portion 81 (see FIG. 7).
More specifically, the pads 71 to 74 are supported so as to be swingable around a swing axis Xa extending in the running direction (horizontal direction) X of the frame body 11 with respect to the second support portions 81b to 84b. Yes. That is, when the pads 71 to 74 are swung in a state where they are located at the retracted positions, the second support portions 81b in a swingable state in which both ends of the pads 71 to 74 can be moved close to and away from the panel surface s. It is supported by ~ 84b.
When the pads 71 to 74 installed in such a state are moved to the contact position and pressed against the panel surface s, the entire width of the pads 71 to 74 is more in contact with the panel surface s. It can be said that the configuration can be surely realized.

Further, as shown in FIG. 9, each of the pads 71 to 74 is arranged with a gap C secured between adjacent pads (pad 71 and pad 72 in FIG. 9). It can swing independently of the pad.
By the way, it can be said that the surface of the solar panel P is generally a flat surface, and it is considered as such. However, when a coating liquid is applied to the surface of the solar panel P using a pad having a certain length (for example, the length of the width dimension of the panel plate constituting the solar panel P), an uncoated portion is generated. was there.
Therefore, when the application test was repeated, the surface of the solar panel P can be said to be a complex surface (uneven surface or undulated surface) including waviness and unevenness of various scales in detail. Thus, it has been found that the above-described uncoated portion may occur due to such a state. Accordingly, further investigations have been made on the application pad, and the application unit 70 of the application apparatus of this embodiment is used. The application unit 70 is composed of a plurality of pads 71 to 74, and each pad 71 to 74 can swing independently about the swing axis Xa (see FIG. 7) in the traveling direction X, so By swinging the pads 71 to 74 corresponding to the unevenness of the surface of the panel P, it is possible to maintain and maintain the state in which the entire width direction of each pad is in contact with the surface of the solar panel P more reliably. It is more reliably prevented that an uncoated part is generated.

And as above-mentioned, the outer side cloth part 76 is comprised by the integral cloth part arrange | positioned at the panel surface side of all the core parts with which each pad 71-74 is provided. More specifically, the present embodiment is configured to include an integrated (one piece) outer cloth portion 76 that wraps the outside of all the pads.
Since each of the pads 71 to 74 can swing independently, the panel is basically oriented in a direction suitable for the state of the panel surface s with which the pad abuts (state of unevenness or undulation). In the case of a configuration in which the outer sides of all the pads 71 to 74 are wound with an integral cloth portion 76 as in the present embodiment, the outer cloth portion 76 is in contact with the surface s. It functions as a member that suppresses the displacement of the positions of the end portions 71e and 72e in FIG. That is, it can be said that the outer cloth portion 76 has a function of adjusting the swinging direction of the adjacent pads to be continuous. As a result, the pads 71 to 74 arranged in series so as to be independently swingable are allowed to swing in suitable directions, and the entire pad is smoothly oriented in a continuous direction. Can do. Thereby, it can prevent that an uncoated part arises, respond | corresponding to the unevenness | corrugation and wave | undulation of various scales of the surface of the solar panel P. FIG. Such an outer cloth part 76 can be called, for example, a correction member (correction means) for the orientation of the pads 71 to 74, and can be called an interlocking member (interlocking means) for the direction of the adjacent pads 71 to 74.

  The inner cloth part 75 and the outer cloth part 76 are materials that allow the coating liquid impregnated in the core parts 71c to 74c to ooze out to the panel surface side in a state of being in contact with the panel surface s. In this embodiment, the same nonwoven fabric is used for both the cloth portions 75 and 76.

  According to the coating apparatus 1 configured as described so far, after the coating apparatus is installed on the panel P for photovoltaic power generation, the coating liquid is supplied to the coating unit 70 and the pad of the coating unit 70 is moved to the coating position. When the frame portion 10 is moved in the horizontal direction with the pad in contact with the panel surface s, the coating liquid can be applied to the panel surface s.

  Next, the procedure of the coating operation using the above-described coating apparatus will be described.

When attaching the coating device 1 to, for example, a solar panel P installed outdoors, first, the frame portion 10 is attached to the solar panel P. Specifically, the upper end engaging portion 21 of the frame portion 10 is hooked on the upper end edge Pa of the solar panel P (see FIG. 1). As a result, the upper end rollers 22, 22 of the upper end engaging portion 21 come into contact with the upper surface of the upper end edge Pa in a state where the upper end rollers 22, 22 can roll in the traveling direction X along the upper end edge Pa. When the self-propelling motor is operated in this state, the frame portion 10 can be moved in the traveling direction X.
Next, the lower end engaging portion 31 is moved to bring the lower end rollers 32 and 32 into contact with the lower end edge Pb of the panel P, and the lower end engaging portion 31 is fixed at this position (panel contact position). Thus, the frame unit 10 is installed in a state in which the solar panel P is sandwiched between the upper end roller 22 and the lower end roller 32 and is capable of traveling in the traveling direction X.

  Next, the moving body 40 is installed on the frame unit 10. Specifically, the guide rail 11c is sandwiched between the vertical drive rollers 42 and 42, and the driven rollers 43 and 43 are brought into contact with the upper surfaces of the rail portions 11a and 11b of the frame body 11. Accordingly, when the vertical movement motor is operated, the moving body 40 can be moved in the vertical direction Y (direction orthogonal to the traveling direction of the frame portion 10) along the longitudinal direction of the frame portion 10.

  Next, the coating operation by the coating apparatus that has been installed will be described.

  First, the traveling motor is operated to move the frame portion 10 to a position on the left end side of the solar panel P (a position on the left side of the position shown in FIG. 1). Then, the vertical movement motor is operated to move the moving body 40 to the uppermost height position of the frame portion 10 (refer to the first height position, the height position of the moving body 40 shown in FIG. 1).

Next, the swing mechanism 85 is operated to move the other application part (application part arranged on the left side in FIGS. 3 and 5) 70 to the contact position (pad contact process, FIG. )reference).
Thereby, the other application part 70 (the edge part 70a) is in a state of being in contact with the position of the upper end side of the left end of the surface of the solar panel P. It should be noted that, after the installation of the coating device 1 is completed, the coating liquid is applied from the tank 77a via the tube 77b to the pads 71˜ of the coating unit 70 at a predetermined timing before the coating unit 70 is brought into contact with the surface of the solar panel P. Supply to 74.

In this state, the driving motor is operated to move the frame portion 10 to the right side. Thereby, the other application part 70 moves to the right side, and the application liquid is applied to the uppermost part of the surface of the solar panel P by the application part 70. When the frame unit 10 moves to the right end side of the solar panel P, the traveling motor is stopped and the frame unit 10 stops traveling.
At this time, the other application unit 70 has not moved to the right end Pr of the solar panel P (see FIG. 5A), and the application operation has not been completed on the right end side of the solar panel P. A front region D (see FIG. 5A) occurs. The application of the pre-application area D will be described later.

When the frame unit 10 stops, the other application unit 70 is then moved from the contact position to the retracted position.
In addition, after the start of the movement of the other application unit 70, the vertical movement motor is operated to move the moving body 40 downward and to the second height position.
The second height position of the application unit 70 is a position where the upper end position of the application unit 70 at the second height position is lower than the upper end position of the application unit 70 at the first height position, and the first height position. It is a position that is in a higher position than the lower end position of the application part 70 in the position.

Next, the swing mechanism 85 is operated to move one application part (the right application part in FIG. 3) 70 to the contact position.
Thereby, one application part 70 contact | abuts to the 2nd height position of the right end of the solar panel surface s (refer FIG.5 (b)).

In this state, the traveling motor is operated to move the frame portion 10 to the left side. Thereby, one application part 70 moves to the left side, and the application liquid is applied to the second height portion of the surface of the solar panel P by the one application part 70.
If the second height position of the coating unit 70 is the position as described above, an overlapping portion is generated between the coating region at the first height position and the coating region at the second height position, and the uncoated portion. Is prevented from occurring.

When the frame unit 10 moves to the left end side of the solar panel P, the traveling motor is stopped and the frame unit 10 stops traveling.
In addition, during traveling to the left side of the frame portion 10 at the second height position, the coating liquid can be manually applied to the above-described region before coating. In this case, the area of the region to be manually applied can be suppressed to the minimum, and the occurrence of an uncoated region can be prevented more reliably.

When the frame unit 10 stops, next, one application unit 70 is moved from the contact position to the retracted position.
In addition, after the movement of one application unit 70 is started, the vertical movement motor is operated to move the moving body 40 downward and move to the third height position.
When the movement of the moving body 40 is completed, the swing mechanism is operated to move the other application unit 70 to the contact position again (pad contact process).
Thereafter, the same operation as the series of operations described so far is repeated until the application of the lowermost region of the surface of the solar panel P is completed.

  Thus, if the coating device of this embodiment is used, a coating liquid can be apply | coated to the surface front surface of the solar panel P easily, rapidly and reliably.

The coating operation described so far is a method using manual coating for coating a part of the region.
And according to the coating device 1 of this embodiment, the method of apply | coating all the area | regions with a coating device can be performed so that it may demonstrate below.
Since the operation up to the first pad contact process is the same as that described above, the description thereof is omitted.

  In a state where the first pad contact process described above is completed, the traveling motor is operated to cause the frame portion 10 to travel to the right side. Thereby, the other application part 70 moves to the right side, and the application liquid is applied to the uppermost part of the surface of the solar panel P by the application part 70. When the frame unit 10 moves to the right end side of the solar panel P, the traveling motor is stopped and the frame unit 10 stops traveling. At this time, the above-mentioned pre-application region where the coating liquid is not applied exists below the frame portion 10.

When the frame portion 10 stops, the swing mechanism 85 is then operated to move the other application portion 70 from the contact position to the retracted position.
Further, the swing mechanism 85 is operated to move one application unit 70 to the contact position. Thereby, one application part 70 contacts the upper end part of the right end of the panel surface s of the solar panel P. In this state, the traveling motor is operated to move the frame portion 10 to the left side. Thereby, a coating liquid is apply | coated to the area | region before application | coating mentioned above.

Thereafter, when the frame portion 10 moves to the left end side, the traveling motor is stopped, and the frame portion 10 stops traveling.
When the frame part 10 stops, one application part 70 is moved from the contact position to the retracted position.
Further, after the movement of one application unit 70 is started, the vertical movement motor is operated to move the moving body 40 downward and to the second height position.

Then, when the movement of the moving body 40 to the second height position is completed, the swing mechanism is operated to move one application unit 70 to the contact position again (pad contact process).
Thereafter, the same operation as the series of operations described so far is repeated until the application of the lowermost region of the surface of the solar panel P is completed.

  If it does in this way, a coating liquid can be apply | coated to the surface front surface of the solar panel P easily, rapidly and reliably, without performing application | coating by manual operation using the coating device of this embodiment.

  And even if it uses which application | coating procedure mentioned above, in the coating device 1 of this embodiment, in the state which contact | abutted the corner | angular part 70a (refer FIG. 5) of the pads 71-74 to the surface of the solar panel P Since the coating operation is performed, the coating quality is stabilized. Further, although the surface s of the solar panel P is basically a flat surface, it has irregularities and undulations of various scales, but the pads 71 to 74 of the coating unit 70 of the coating apparatus of the present embodiment are Since each can swing independently, it can swing in the direction corresponding to the above-mentioned undulation and can come into contact with the surface of the solar panel P, so the occurrence of an uncoated portion can be prevented more reliably. . Further, since the plurality of pads of each application unit 70 are wound by one outer cloth portion 76, the pads 71 to 74 arranged in series are allowed to swing in a suitable direction, and the pads It is possible to realize a state in which the whole is directed smoothly in a continuous direction, and the occurrence of an uncoated portion is more reliably prevented.

  The coating apparatus according to the present invention is not limited to the one described in the embodiment. A coating device modified within the scope of the present invention is included in the scope of the present invention.

  For example, the support portions 81 to 84 are constituted by a first support portion and a second support portion, but various support structures that can move the application portion to the contact position and the retracted position can be used. is there.

Further, the pads 71 to 74 of the coating apparatus of the present embodiment have a rectangular cross-sectional shape orthogonal to the frame longitudinal direction (vertical direction), but if the shape has a ridge-like edge, Not limited.
The pads 71 to 74 having a rectangular cross section come into contact with the panel surface s at the edge portion 70a (see the corner portion 70a in FIG. 5) located at the lowermost end of the rectangle. Thus, when the pad is positioned at the contact position, a configuration in which the width of the contact portion with the panel surface of the pad is shorter than the width of the pad is preferable. And the contact position with the panel surface of a pad is not specifically limited, However, It is preferable to be located behind a pad advancing direction rather than the center position of the width direction of a pad.

The number of pads on one application part 70 is preferably 2 or more and 10 or less, and more preferably 4 or more and 6 or less. The length of the pad in the longitudinal direction of the frame is preferably 10 cm or more and 1 m or less.
Moreover, although the application part 70 is a pair of right and left arrangement | positioning in the coating device 1 of this embodiment, only any one may be sufficient. When there is one application unit, one application unit may be configured to include either one of the pair of application units of the present embodiment, or may be an application unit installed in another part.

  Moreover, although the coating device 1 of this embodiment is suitable as a device which apply | coats a coating liquid to the surface s of the photovoltaic power generation panel P installed outdoors, it compares not only indoors and outdoors but like a photovoltaic power generation panel. It can be used as an apparatus for applying a coating liquid to a wide application target surface. Moreover, although the coating device 1 of this embodiment is suitable as a coating device which apply | coats a coating liquid to the inclined plane like a solar panel, as a device which applies a coating liquid with respect to the application | coating surface spread horizontally. It can be used.

  The coating apparatus 1 according to the embodiment described above includes the frame lower end portion 30, but may be a coating apparatus having a configuration that does not include this. The coating apparatus of the present embodiment includes a frame lower end 30 and can be installed with the panel P sandwiched from above and below, and can be installed in a state in which play is unlikely to occur, and is applied to a coating surface that spreads horizontally. It is excellent in that it can be applied to liquid application. On the other hand, the coating device having a configuration that does not include the lower end of the frame is lightweight and can be easily installed and removed, and the pad is provided with a force to press the lower end of the running frame 10 against the panel surface by the operator himself / herself. It can be said that it is excellent in that a pressing pressure is applied, a reverse force is applied to reduce the pad pressing force, and the pad pressing force can be easily adjusted. In addition, when the frame lower end part 30 is provided, a motor for causing the frame lower end part 30 to self-run may be provided.

Moreover, in the coating device 1 of this embodiment, although both the inner cloth part 75 and the outer cloth part 76 are used as what wraps the outer side of the pads 71-74, even if it is the structure which uses only any one. Good.
For example, as shown in FIG. 8, when only the outer cloth portion 76 is used, the thickness of the cloth portion is reduced by the amount that the inner cloth portion 75 does not exist without impairing the effect of the outer cloth portion 76 described above. Therefore, it is preferable in that the elasticity of the sponge constituting the pad can be used more effectively. Further, if only the outer cloth portion 76 is used, the influence of friction between the inner cloth portion 75 and the outer cloth portion 76 is eliminated, so that the adjacent pads 71 to 74 are compared with each other compared to the case where the inner cloth portion 75 exists. While maintaining the interlocking, the swing range of each pad 71 to 74 is widened (easiness of swinging is further improved), which is preferable in that it can flexibly cope with various swell shapes on the surface of the panel P. .
In addition, when only the inner cloth portion 75 is used, it is not a configuration in which all the pads are wound around the integral cloth portion, and thus independent swinging of each pad becomes easier. In the case where only the inner cloth portion (coating member) 75 is used, it is more preferable that the ends of the inner cloth portions wound around the adjacent pads are in contact with each other. With such a configuration, the occurrence of an unapplied portion is more reliably prevented, and the swing of one pad arbitrarily selected from a plurality of pads is performed, as in the case where all the pads are wound with an integral cloth portion. Can be transmitted to the pads arranged adjacent to the one pad via the inner cloth portions 75 and 75 (interlocking members) in contact with each other.
