Description

Module used for stacking thin panels

The present invention relates to a module used for stacking thin panels, and more specifically, a module used for stacking and supporting thin panels such as a plurality of solar panels in the vertical direction for storage and transportation. About.

A solar panel has a thin plate shape in which cells are connected in series and protected by resin or tempered glass. More specifically, a cell made of silicon is interposed between a glass layer and a plastic layer, or between a glass layer and a glass layer. It is an embedded laminated structure, and has a thickness of several millimeters, an area of several square meters, and a weight ranging from 10 to 30 kg. Therefore, it is a precise and fragile structure.

Such solar panels are transported by vehicles such as trucks from manufacturing plants to rooftops and roofs of buildings and houses, which are relatively remote locations. Receive.

Conventionally, two types of means have been known for stacking and transporting thin panels that are relatively large and fragile, such as solar panels.

In the first type, as disclosed in Patent Document 1, the periphery of the thin panel is damaged by fitting a frame formed of plastic or light metal on the four sides which are the most fragile parts of the thin panel. After being protected, the module is placed on a module (also referred to as a corner material) located at the four corners of the thin panel, and the thin panel with the four sides protected and the module are alternately placed. By doing so, a laminated body of thin plate panels is formed.

However, with this means, a large number of frames corresponding to the number of four sides of the thin panel to be transported are required, which reduces the transport efficiency of the thin panel.

Therefore, as disclosed in Patent Document 2, as a second type conveying means, a module disposed at the four corners of the thin panel without using a costly frame has the same dimensions as the thickness of the thin panel. It is known that a groove portion is formed and a corner portion of the thin plate panel is sandwiched in the groove portion, thereby suppressing vibration and vertical flapping during conveyance of the thin plate panel, thereby preventing damage.

However, as described above, the thin panel, particularly the solar panel, is made of a brittle material such as glass. Therefore, the corners of the four corners are particularly easily damaged, and such a portion has the same dimensions as the thickness of the thin panel. Inserting the groove into the groove portion was a cumbersome operation.
Furthermore, when stacking solar panels on a pallet in a solar panel packaging line, the sandwich type module as described in Patent Document 2 arranges the modules at its four corners before stacking the solar panels. It is necessary to let Specifically, with the corners of the solar panel sandwiched between the modules, the modules placed on the solar panels to be stacked are stacked while aligning the modules at the four corners placed on the lower stage. There is a need. For this reason, after placing only the modules with respect to the four corner modules arranged in the lower stage, the solar panel is placed along the four corner modules arranged in a predetermined position. This will not be possible and will limit the packaging line for solar panels.
JP 2006-32978 A European Patent EP2320157A2

Therefore, in view of the above technical problems, the object of the present invention is applied to a thin plate panel that does not have a protective member such as a frame on the outer periphery, in particular, a solar panel. It is a module arranged at the four corners or other edges of the panel, and by simply stacking the modules and thin plate panels alternately, it is possible to easily construct a laminate for transportation, It is an object of the present invention to provide a module used for stacking thin panels that can effectively prevent fluttering and breakage of the thin panels due to an impact, and can greatly reduce the number of steps required for carrying work.

In order to solve the above problem, a module used for stacking thin plate panels according to the present invention is:
A support part that supports the thin panel from below, a load transmission part that is connected to the support part and transmits the weight of the thin panel in the vertical direction, and a positioning that horizontally positions the thin panel stacked vertically A module used for stacking thin plate panels,
The support portion has a support surface on which the thin plate panel is placed,
The load transmitting portion is formed outside the support surface and has an upper portion that receives the upper module when the module is stacked, and a bottom portion that transmits a load to the upper portion of the lower module when the module is stacked,
A lower projecting portion capable of being opposed to the upper surface of the thin panel supported by the lower module is provided, and a lower end of the lower projecting portion is located below the bottom portion;
It is configured.

According to the module used for stacking the thin plate panels having the above-described configuration, the module is configured by the stacked modules and the load transmitting unit that supports the weight of the thin plate panel, and the support unit for supporting the thin plate panel. Therefore, characteristics suitable for each purpose can be given to both. However, as will be described later, the two modules do not need to be physically separable, and are deliberately separated from their functions. For example, the entire module is integrated by plastic resin injection molding or the like. It does not prevent it from forming.

The module may be disposed at each of the four corners of the rectangular thin plate panel, the support surface may have an L shape, and the positioning portion may have a standing wall surface extending upward from an outer edge of the support surface. As a result, it is possible to position the rectangular thin panel by suppressing the outward movement of the rectangular thin panel by placing the rectangular thin panel on the support surface so as to contact the standing wall at each of the four corners of the rectangular thin panel. It is.
Then, the size of the downward projecting portion may be a size that allows the lower end of the downward projecting portion of the module placed on the upper side to hit the upper surface of the thin panel when the thin plate panel is placed on the support surface.
In order to prevent cracking by preventing the thin panel from flapping up and down during transportation of stacked thin panels, it is only necessary to be able to regulate the vertical amplitude of the thin panels due to vibration. When there is no vibration, it means that a slight gap is allowed between the downward projecting portion and the upper surface of the thin panel.

According to the module used for stacking the thin plate panels having the above configuration, the thin plate panel is placed on the support surface of the module and the upper module is placed thereon in order to form a laminate of the thin plate panels. Then, a thin plate panel is inserted between the lower end of the downward projecting portion of the module and the support surface, and an effect substantially equivalent to that of the second type prior art is obtained. That is, by sandwiching the supported portion (for example, the corners of the four corners) of the thin panel, vibrations during the transportation of the thin panel and vertical fluttering can be suppressed, thereby preventing damage.

Here, in the load transmission part and the downward projection part that are separated conceptually as described above (although not necessarily physically separated), the vertical rigidity of the load transmission part depends on the vertical direction of the downward projection part. It is better to have a configuration that is stiffer than rigid.

According to the module used for stacking the thin plate panels having the above-described configuration, the weight of the laminated body is supported, and so to speak, the load transmitting portion serving as the structural support of the laminated body is given rigidity capable of sufficiently supporting the weight. On the other hand, the lower protrusion of the upper module, which has the purpose of holding the upper surface of the thin plate panel, is kept low in rigidity (softened), and the weight of the entire upper laminate is reduced through the lower protrusion. Prevents the top panel from being applied

Therefore, in the module used for stacking the thin panel according to the present invention, it is preferable to form both the load transmitting portion and the downward projecting portion in a hollow structure.
Thereby, it becomes possible to form a plurality of ribs in the hollow space formed in the hollow in the load transmitting portion and the downward projecting portion.

Then, the thickness of the rib formed in the hollow space in the load transmitting portion is made thicker and / or the load transmitted than the thickness of the rib formed in the hollow space in the downward projecting portion. The number of ribs formed in the hollow space in the portion is increased compared to the number of ribs formed in the hollow space in the downward projecting portion, and / or in the hollow space in the load transmitting portion. It is possible to adopt a configuration in which the interval between the formed ribs is made denser than the interval between the ribs formed in the hollow space in the downward projecting portion.

According to the module used for stacking the thin panel having the above configuration, the vertical rigidity of the load transmitting portion can be easily reduced by appropriately designing the thickness, number of installations, or interval of the ribs. Compared to the vertical rigidity of the protrusion, the rigidity can be made suitable.

In addition, in order to make the vertical rigidity of the load transmission part stiffer than the vertical rigidity of the downward projecting part, the wall thickness of the outer surface of the load transmission part formed in the hollow is It is preferable that the thickness is larger than the thickness of the rib formed in the hollow space in the load transmitting portion.

Furthermore, when the load transmitting part and the downward projecting part are formed hollow, the bottom part of the downward projecting part is preferably open.

When the bottom surface is formed by closing the bottom of the downward projecting portion, dust or dust adheres to the bottom surface, and the bottom surface (that is, the lower end of the downward projecting portion) is in contact with the surface of the lower thin panel. However, by opening the bottom surface, it is possible to prevent dust and dust from adhering to the bottom.

In this case, it is preferable that the lower end of the rib formed in the hollow space in the downward projecting portion is extended so as to coincide with the end surface of the bottom portion of the downward projecting portion.

Thereby, the lower end of the lower protruding portion contacts not only the peripheral edge of the lower protruding portion but also the rib in the lower protruding portion, so that the force by which the lower protruding portion presses the thin panel from above can be distributed more uniformly.

In addition, this invention is not restricted to the structure mentioned above, For example, the load transmission part and the downward protrusion part can also be set as the structure currently formed.

In this case, the load transmitting part and the downward projecting part are made of different materials, and the rigidity of the material constituting the downward projecting part is set lower than the rigidity of the material constituting the load transmitting part. good.

Further, it is possible to adopt a configuration in which one of the load transmitting portion and the downward projecting portion is formed hollow and the other is formed solid.

In order to solve the above problem, a module used for stacking thin plate panels according to the present invention is:
A support part that supports the thin panel from below, a load transmission part that is connected to the support part and transmits the weight of the thin panel in the vertical direction, and a positioning that horizontally positions the thin panel stacked vertically A module used for stacking thin plate panels,
A main body that supports the weight of the module and the thin panel when a plurality of modules are stacked; an upper part that is formed outside the support and receives the upper module when the modules are stacked; and And a bottom part for transmitting a load to the upper part of the lower module when stacked,
The lower surface of the thin panel is in contact with a support surface formed on the upper surface of the support portion, and the upper surface is in contact with the lower end surface of the stacked upper module.
, The configuration.

Hereinafter, the first embodiment of the module 10 according to the present invention will be described in detail with reference to the accompanying drawings, taking as an example the case where a solar panel P is used as a stacked thin panel. FIG. 1 is a schematic view showing a use state of a module according to the first embodiment of the present invention, and FIG. 2 is a perspective view showing the module and the solar panel P in the use state of FIG. 3 (a) to 3 (f) show the module according to the first embodiment of the present invention, (a) top view, (b) bottom view, (c) outer side view, (d). FIG. 6 is an inner side view, (e) a cross-sectional view along line ee, and (f) a cross-sectional view along line ff.

The solar panel P has a rectangular shape and is directly supported by the module 10 at each of the four corners without fitting a frame formed of plastic, light metal, or the like around the periphery.
As shown in FIGS. 1 to 3, the module 10 is interposed between the solar panels P in order to stack and support a plurality of solar panels P. And the solar panel P, the load transmitting part 20 mainly serving to support the total weight and the support part 40 for supporting the corners of the four corners of the solar panel P are schematically configured.

The load transmitting unit 20 is formed in an L shape that is complementary to the corners of the four corners that are the supported portions of the solar panel P, and the positioning unit 22 is opposite to the solar panel P. A laterally spaced outer surface 24, a top portion 26 that receives the upper module when the module 10 is stacked, and a bottom portion 28 that transmits load to the upper portion 26 of the lower module when the module 10 is stacked. is doing.
On the other hand, the support part 40 has a support surface 42 extending horizontally from the positioning part 22 of the load transmitting part 20 and a lower side of the support surface 42 below the bottom part 28 to support one solar panel P. And a downward projecting portion 44 projecting from the bottom.

More specifically, in the positioning unit 22, the module 10 is disposed at each of the four corners of the solar panel P, the support surface 42 has an L shape, and the positioning unit 22 is located upward from the outer edge of the support surface 42. It has a standing wall 23 extending to 26. Thereby, in each of the four corners of the solar panel P, by placing the solar panel P on the support surface 42 so as to contact the standing wall surface 23, the outward movement of the solar panel P is suppressed, It is possible to position.
Further, as shown in FIG. 2, the upper portion 26 constitutes an L-shaped load receiving surface, while the bottom portion 28 constitutes an L-shaped load releasing surface, and the downward projecting portion 44 extends downward from the bottom portion 28. It has the outer side surface 27 extended to the contact part 45 (it demonstrates later) which is a lower end of a protrusion part.
Thus, when the modules 10 are stacked at each of the four corners of the solar panel P, as shown in FIG. 1, in the modules 10 adjacent in the vertical direction, the outer surface 27 of the upper module 10 is By placing the load release surface of the upper module 10 on the load receiving surface of the lower module 10 so as to abut against the wall surface 23, the relative movement of the upper module 10 to the lower module 10 is suppressed. Therefore, it is possible to position the solar panels P stacked in stages through the module 10 in the horizontal direction.

The contact portion 45 will be described. The lower surface of the downward projecting portion 44 is formed, and the lower surface is formed in parallel with the support surface 42. When the modules 10 are stacked, as shown in FIG. As described above, by placing the upper module 10 on the lower module 10, the contact portion 45 of the upper module 10 faces the upper surface of the solar panel P supported by the lower module 10. Provided to abut.
As a result, the four corners of the solar panel P are firmly sandwiched between the support surface 42 of the module 10 supporting the solar panel P and the contact portion 45 of the module 10 at the upper level. The solar panel P does not flutter or rattle.

The size of the contact portion 45, that is, the width of the lower surface of the downward projecting portion 44 may be determined from the viewpoint of effectively preventing such fluttering and rattling during the transportation of the solar panel P. FIG. As shown in FIG. 3, it is not necessarily the same area as the support surface 42.

The load transmission unit 20 and the support unit 40 are described as if they were separate independent members. However, in general, the load transmission unit 20 and the support unit 40 are formed from a single member integrally molded by plastic injection molding or the like. It is configured (see FIG. 3 (e)).
In this respect, the resin material of the module is a thermoplastic resin, and is an olefin resin such as polyethylene or polypropylene, or an amorphous resin, and more specifically, ethylene, propylene, butene, isoprene pentene, methyl pentene, or the like. It is a polyolefin (for example, polypropylene, high density polyethylene) which is a homopolymer or copolymer of olefins, and the structure of the module 10 is relatively complicated. Therefore, it is particularly suitable for integral molding by injection molding.

In the present embodiment, both the load transmitting portion 20 and the downward projecting portion 44 of the support portion 40 have a hollow structure. That is, as best shown in FIG. 3B, in the load transmitting portion 20, four L-shaped sides are provided between the outer surface 24 and the positioning portion 22, and a total of 8 L-shaped portions. A plurality of ribs 30 are extended, and a hollow space 32 is opened between the rib 30 and the adjacent rib 30. Similarly, a total of five ribs 46 extend from the downward projecting portion 44 of the support portion 40, and a space between the rib 46 and the adjacent rib 46 is opened as a hollow space 48. The hollow space 48 is wider than the hollow space 32 due to the difference in the number of installed

ribs

30 and 46. Furthermore, the thickness of the rib 30 is 2.5 mm, the thickness of the rib 46 is 2.0 mm, and the rib 30 provided in the load transmitting portion 20 is more in the rib 46 provided in the downward projecting portion 44. It is thicker than As shown in the cross-sectional view of FIG. 3 (f), these

ribs

30, 46 are vertically projecting from the upper part 26 to the end face of the bottom part 28 in the rib 30 of the load transmitting part 20. The ribs 46 are continuously provided vertically from the support surface 42 to the end surface of the lower end thereof, and each of the load transmitting portion 20 and the downward projecting portion 44 serves as a support member for a load in the vertical direction. It has become. As a result, the vertical rigidity of the load transmitting portion 20 is stiffer than the vertical rigidity of the downward projecting portion 44.

When the solar panel P is transported by a truck or the like using the module according to the present embodiment configured as described above, first, four modules 10, one at each of the four corners of the pallet 54, It installs so that it may correspond to the corner | angular part of the panel P, the solar panel P is moved above it, the solar panel P is dropped on the support surface 42 of the support part 40 of each module 10, and the solar panel P The corner portion is placed so as to contact the positioning portion 22 of the module 10. Thereby, the loading of the first solar panel P is completed.

Next, the bottom portions 28 of the four modules 10 newly prepared are placed so as to overlap the upper portions 26 of the four modules 10 installed on the pallet 54. Then, as before, the second solar panel P is moved above the pallet 54, the solar panel P is lowered on the support surface 42 of the support part 40 of the new module 10, and the solar panel P Is placed so that the corners of the module are in contact with the positioning part 22 of the module 10. At this time, since the outer surface 27 of the downward projecting portion 44 of the new module 10 abuts against the standing wall 23 of the lower module 10, even if the solar panel P is shaken in the horizontal direction, the new module 10 10 does not shift outward in the radial direction, and the four corners of the solar panel P are reliably positioned by the positioning portion 22. Thereby, the loading of the second solar panel P is completed.

As shown in FIG. 4, by repeating this process, the modules 10 and the solar panels P are alternately stacked, and when the required number is reached, the top plate 56 is placed on the upper surface of the laminate. After placing and binding the rope 58 in the vertical direction from the bottom surface of the pallet 54 to the top surface of the top plate 56, a protective sleeve (not shown) is placed on the outer periphery to complete the transport unit 60. Then, the transport unit 60 is loaded on a truck or the like and transported to the installation site of the solar panel P.

During transportation, vibrations accompanying the traveling of the truck are applied to the solar panel P in the vertical and vertical directions, and the four corners of the solar panel P are supported by the module 10 supporting the solar panel P. The solar panel P does not flutter or rattle because it is firmly held between the surface 42 and the contact portion 45 of the module 10 at the upper level. In addition, with respect to the solar panels P arranged in the lower stage of the laminate, the weight of the multiple solar panels P stacked above is supported by the load transmission unit 20 of the module 10 and has a lower rigidity. The load applied to the upper surface of the solar panel P from the protrusion 44 is reduced. As a result, damage to the solar panel P is effectively prevented.

When the truck arrives at the installation site, the transport unit 60 is unpacked. The unpacking is performed in the reverse order to the procedure when the transport unit 60 is formed. That is, first, a protective sleeve (not shown) is removed from the outer surface of the transport unit 60, and then the rope 58 is released. Then, the top plate 56 placed on the upper surface of the laminate is removed. Thereby, the uppermost solar panel P is exposed. The uppermost solar panel P has its four corners positioned from four directions in the horizontal direction by the positioning portions 22 of the module 10, but is not restricted at all in the upward direction. Therefore, it can be taken out from the transport unit 60 as long as it is lifted vertically upward.

When the topmost solar panel P has been installed at the required installation location, the top four modules 10 that have supported the solar panel P at the four corners until then are removed. Since the module 10 is merely placed on the module 10 one level lower, it can be easily removed by pulling upward. As a result, the next-stage solar panel P is exposed. Thus, taking out the solar panel P starts from the topmost one stacked last, contrary to the time of stacking, the taking out of the first solar panel P is performed last, The process ends when the first solar panel P is taken out.

As described above, according to the present embodiment, although it is a simple configuration, it is applied to a thin plate panel, particularly a solar panel, which does not have a protective member such as a frame on its outer periphery, and in order to stack and support it. , Modules arranged at the four corners or other edges of the thin plate panel, and by simply stacking the modules and thin plate panels alternately, it is possible to easily construct a laminate for conveyance and A module used for stacking thin panels that can effectively prevent flapping and breakage of thin panels due to vibrations and shocks, and can greatly reduce the labor required for transporting operations is provided. .

Next, a second embodiment of the present invention will be described in detail with reference to FIGS. In the following description, the same reference numerals are given to the same components as those in the first embodiment, the description thereof will be omitted, and the features of the present embodiment will be described in detail.
The feature of the module 100 according to the present embodiment is the positioning part and the contact part.

As shown in FIGS. 5 and 6, the positioning unit stacks the upper module 100 on the lower module 100 in a form in which the load release surface of the upper module 100 is placed on the load receiving surface of the lower module 100. An upper locking portion 104 for restricting relative movement of the upper module 100 to the lower module 100 provided on the inner edge 102 of the load receiving surface, and the same side as the side on which the upper locking portion 104 of the load release surface is provided. The inner edge 103 has an upper locking portion 104 and a lower locking portion 106 that is provided in a form offset in the horizontal direction and restricts relative movement of the upper module 100 relative to the lower module 100.
More specifically, one upper locking portion 104 is provided on each side of the intersection portion of the L-shaped load receiving surface, and one lower locking portion 106 is provided on each side of the intersection portion of the L-shaped load release surface. The upper locking portion 104 and the lower locking portion 106 are provided so as to substantially cover the

inner edges

102 and 103 of the standing wall 22 in cooperation with each other. The upper locking portion 104 is provided on the proximal side of the intersection portion of the L-shaped load receiving surface, and the lower locking portion 106 is provided on the distal side of the intersection portion of the L-shaped load release surface.

Each of the upper locking portions 104 has an inclined portion 110 that is inclined inward from the inner edge 102 of the load receiving surface upward from the load receiving surface, and is fixed to the inner surface of the standing wall 22. As described later, the height H1 of the upper locking portion 104 from the load receiving surface is such that when the modules 100 are stacked, the upper locking portion 104 of the lower module 10 is positioned between the modules 100 adjacent in the vertical direction. Since the front end of the upper part extends partway along the inner surface of the standing wall 22 of the upper module 100, it may be set appropriately so as not to hit the lower surface of the support surface 42 of the upper module 10.

On the other hand, each of the lower engaging portions 106 has an inclined portion 113 that is inclined inward from the inner edge 103 of the load releasing surface downward from the load releasing surface, and is fixed to the inner surface of the standing wall 22. . As described later, the height H2 of the lower locking portion 106 from the load release surface is such that when the modules 100 are stacked, the lower locking portion 106 of the upper module 100 is located between the modules 100 adjacent in the vertical direction. Since the tip of this part extends to the middle of the inner surface of the standing wall 22 of the lower module 100, it may be set appropriately so as not to hit the upper surface of the support surface 42 of the lower module 10.

Thereby, between the modules 100 adjacent to each other in the vertical direction, the upper locking portion 104 of the lower module 100 restricts the upper module 100 from moving inward relative to the lower module 100. The lower locking portion 106 of the module 100 restricts the upper module 100 from moving outward relative to the lower module 100, so that the upper module 100 moves inwardly with respect to the lower module 100. The relative movement to the outside is suppressed, and the modules 100 can be stacked stably. In particular, the module is formed in an L-shape, and on each side across the intersection, an upper locking portion 104 in the upper plate-like body 12 and a lower locking portion 106 in the lower plate-like body 14. Accordingly, the two orthogonal directions on the horizontal plane can be regulated correspondingly, and more specifically, inward in the two orthogonal directions with respect to the module 100 below the upper module 100. Restriction is made, and restriction in the two orthogonal directions to the lower module 100 on the one upper module 100 is made.

According to the above configuration, the upper locking portion 104 and the lower locking portion 106 are provided on the inner edge 102 of the load receiving surface and the inner edge 103 of the load releasing surface, respectively. The upper and lower locking portions 106 are not provided on the upper and load releasing surfaces, and the load receiving surface and the load releasing surface are made as small as possible by ensuring a sufficient load transmission area, and the outside of the module 100 itself. By avoiding overhanging, the compactness of the module 100 can be maintained.
On the other hand, with respect to the contact portion 45, unlike the case in which the downward projecting portion 44 is formed so as to cover the entire region of the support portion 40 in the first embodiment, the lower locking portion 106 is moved downward in the second embodiment. The lower projecting portion 44 is provided to extend to the lower end, and the contact portion 45 is provided at the lower end thereof. The contact portion 45 is provided in parallel with the support surface 42, and the downward extension length H2 of the contact portion 45 is such that when the module 100 is stacked, the contact portion 45 that can extend from the upper module supports the lower module. It suffices if the upper surface of the solar panel P placed on the surface 42 can be hit, and the installation position and the size of the hitting portion 45 may vary during transportation of the stacked solar panels P. What is necessary is just to determine suitably from a viewpoint which prevents rattling. The contact portion 45 may taper downward. As a modification, the upper locking portion 104 is provided on the distal side of the intersection of the L-shaped load receiving surface, and the lower locking portion 106, that is, the lower protrusion 44 is located proximal to the intersection of the L-shaped load release surface. It may be provided on the side.
According to such a configuration, in the first embodiment, in order to provide the contact portion 45, the entire lower protruding portion 44 protrudes downward, but the lower locking portion 106, which is a positioning portion, is used to locally In particular, by providing the contact portion 45, it is possible to reduce the amount of the required resin material.

The embodiments of the present invention have been described in detail above, but various modifications or changes can be made by those skilled in the art without departing from the scope of the present invention.
For example, in the said embodiment, although demonstrated that there was no clearance between the downward protrusion part 44 and the solar panel P, it is not limited to it, The solar panel in which the downward protrusion part 44 is conveying As long as fluttering of P can be prevented, the solar panel P may have a clearance of about several mm.
In the present embodiment, in order to stack a plurality of solar panels P in the vertical direction, the same module 100 is used and stacked in a columnar shape at each of the four corners of the plurality of solar panels P. However, the present invention is not limited thereto. Therefore, since the number of solar panels P supported by the lower layer module 100 is larger, the strength is required accordingly. Therefore, a module 100 having the same outer shape but a different thickness is prepared. A thick module 100 may be employed.
Furthermore, in the said embodiment, the case where each of the four corners of the solar panel P which has a rectangular shape was directly supported by the module 100 used for stacking of thin panel was demonstrated. Accordingly, the horizontal view of the supported portion of the thin panel is a right-angled corner, and the positioning portion 22 that is complementary to this is L-shaped, so that the overall outer shape of the module 10 is also approximately. L-shaped. However, when the thin plate panel is circular, the contour of the supported portion in the horizontal view has a convex arc shape, and the positioning portion 22 which is complementary to this has a concave arc shape. Needless to say.
