  In recent years, various products have appeared as sheet-like products. For example, as an example of the sheet-like product, a protective sheet for protecting the back surface for solar cells can be exemplified.

  However, such a sheet-like product is formed with a small thickness while having a large planar dimension. Therefore, after stacking each sheet-like product, the individual sheet-like products are likely to be displaced. As a result, if the individual sheet-like products are displaced, it becomes difficult to cover the sleeve from the top of the laminate, and the packaging work There was a problem that efficiency would deteriorate.

  On the other hand, it is conceivable to increase the working efficiency of the packaging by increasing the inner dimension of the sleeve. However, when the inner size of the sleeve is increased, the manufacturing cost of the package increases, the transport efficiency of the package decreases, and the storage efficiency of the storage space for storing the package decreases. End up. Further, when the inner dimension of the sleeve is increased, the gap between the inner wall surface of the sleeve and the sheet-like product is increased accordingly. For this reason, when the package is transported, the sheet-like product easily moves in the sleeve, and the sheet-like product may be damaged. Therefore, for these reasons, there is a limit to increasing the inner size of the sleeve, and the above problems have not been solved fundamentally.

  The present invention has been made in consideration of such points, and an object of the present invention is to provide a technique for improving the efficiency of the work of packing a laminate of sheet-like products.

  The present invention employs the following configuration in order to solve the above-described problems.

  That is, the packaging body according to the present invention is a packaging body for packaging a laminated body obtained by stacking a plurality of sheet-like products cut into a predetermined shape, and is connected to each other so that the laminated body A plurality of sleeve pieces forming a cylindrical sleeve surrounding the body are provided. And at least one sleeve piece of the plurality of sleeve pieces includes two side walls respectively along two adjacent sides of the laminate, and the two side walls are respectively aligned with the sheet-like products. Is as long as possible.

  In the above configuration, the sleeve surrounding the periphery of the laminated body is divided into a plurality of sleeve pieces. Therefore, in the above configuration, the sleeve is not covered from the top of the laminated body, but a plurality of divided sleeve pieces are arranged around the laminated body from the horizontal direction, and the plurality of sleeve pieces are connected to each other, thereby Can be formed. Therefore, in the above configuration, since it is released from the work process of covering the sleeve from the top of the laminated body, it is not necessary to consider the state of the laminated body when placing the sleeve, and the physical properties of the individual sheet-like products The laminate can be packed without being affected by interference.

  In addition, in the above configuration, at least one of the plurality of sleeve pieces includes two side walls respectively along two adjacent sides of the laminate, and the two side walls are respectively provided for each sheet-like product. It has a length that allows alignment. Therefore, even if the individual sheet-like products are slightly shifted, when the sleeve pieces are combined to form the sleeve, the sleeve pieces are simply positioned around the laminate to align the individual sheet-like products. It can be performed. That is, without increasing the number of work steps, the sheet-like products can be aligned in the vertical direction so as not to interfere with the packaging of the laminate. Therefore, according to the said structure, the efficiency of the operation | work which packs the laminated body of a sheet-like product can be improved.

  As another form of the packaging body, the stacked body includes a first side, a second side adjacent to the first side, a second side adjacent to the first side, and the second side. A third side that faces the first side, and a fourth side that faces the first side and is adjacent to the second side and the third side. There may be two sleeve pieces. The first sleeve piece is connected to a first side wall having a lateral length longer than a length of the first side of the laminated body to be packed, and one end portion in the lateral direction of the first side wall. A second length having a lateral length longer than half of the length of the second side of the laminate so that the sheet-like product can be aligned by bringing the second side of the body into contact with each other. A sidewall and a third sidewall connected to the other lateral end of the first sidewall and having a lateral length shorter than half the length of the third side of the laminate. Good. The second sleeve piece is connected to a first side wall having a lateral length longer than a length of the fourth side of the laminated body to be packed, and one lateral end portion of the first side wall, A second side having a lateral length longer than half of the length of the third side of the laminate so that the sheet-like product can be aligned by contacting the third side of the body. A side wall and a third side wall connected to the other lateral end of the first side wall and having a lateral length shorter than half the length of the second side of the laminate. Good. The first sleeve piece and the second sleeve piece are connected to the second side wall of the first sleeve piece and the third side wall of the second sleeve piece, and the third side wall of the first sleeve piece and the third side wall of the first sleeve piece. The sleeve may be formed by connecting the second side wall of the second sleeve piece.

  In this configuration, the sleeve is composed of two sleeve pieces, and each sleeve piece has a first side wall that is longer than the length of the side of the laminated body and the laminated body so that each sheet-like product can be aligned. A second side wall that is longer than half the length of the side. Therefore, it is possible to reduce the number of steps of connecting the sleeve pieces when forming the sleeve, and by performing the step of surrounding the laminated body with both sleeve pieces, each sheet-like product can be naturally aligned. can do. Therefore, according to the said structure, the efficiency of the operation | work which packs the laminated body of a sheet-like product can be improved especially.

  As another form of the package, the sheet products may be formed in a rectangular shape in plan view, and the first sleeve piece and the second sleeve piece may be formed in the same shape.

  According to this configuration, the first sleeve piece and the second sleeve piece do not have to be produced separately, so that the number of parts can be reduced and the efficiency of producing both sleeve pieces is increased. Therefore, according to the said structure, the manufacturing cost of a package can be suppressed.

  As another form of the packaging body, the first sleeve piece may be configured by laminating two plate-like members while shifting them in the lateral direction. The second side wall of the first sleeve piece is composed of a superposed portion where the two plate-like members overlap each other and a first non-polymerized portion where one plate-like member does not overlap the other plate-like member. Good. The first side wall and the third side wall of the first sleeve piece may be constituted by a second non-overlapping portion where the one plate-like member does not overlap with the other plate-like member. Further, the second sleeve piece may be formed by laminating two plate-like members while shifting them in the lateral direction. The second side wall of the second sleeve piece is composed of a superposed portion where the two plate-like members overlap each other and a first non-polymerized portion where the other plate-like member does not overlap in one plate-like member. Good. The first side wall and the third side wall of the second sleeve piece may be constituted by a second non-overlapping portion where the one plate-like member does not overlap with the other plate-like member. The second side wall of the first sleeve piece and the third side wall of the second sleeve piece are connected to each other between the first non-overlapping portion of the first sleeve piece and the second non-overlapping portion of the second sleeve piece. And the connection between the third side wall of the first sleeve piece and the second side wall of the second sleeve piece may be performed at an end of the second non-overlapping portion of the first sleeve piece. It may be performed in one region on the part side and the first non-polymerized portion of the second sleeve piece.

  In this configuration, each sleeve piece can be formed simply by shifting and laminating the two plate-like members. Therefore, the manufacturing cost of the package can be suppressed. Further, since the two sleeve pieces are connected to each other between the non-overlapping portions, it is possible to prevent the thickness from changing in each side wall of the sleeve. Thereby, according to the said structure, it can prevent that it becomes easy to apply stress to a part of a package, and although it is a simple structure of bonding two plate-shaped members together, it is formed. The strength of the package can be increased.

  As another form of the package, at least one of the four sides of each sheet-like product may have a length of 800 mm or more, and the thickness of each sheet-like product may be 0.5 mm or less. And each said sleeve piece may be dimensioned so that the clearance gap between the inner wall surface of the said sleeve and each said sheet-like product may be 20 mm or less.

  As described above, when the planar dimensions of the individual sheet-like products constituting the laminate are increased and the thickness thereof is reduced, the individual sheet-like products are liable to be displaced, and the work efficiency of packaging the laminate is deteriorated. End up. However, according to the said structure, the work efficiency of packing can be improved by enclosing a laminated body with the some sleeve piece divided | segmented.

  Therefore, according to the said structure, even if each sheet-like product and each sleeve piece are dimensioned as mentioned above, a laminated body can be packed, without deteriorating working efficiency. That is, without deteriorating the working efficiency, a laminate composed of a sheet-like product having a length of at least one of the four sides of 800 mm or more and a thickness of 0.5 mm or less is used as the inner wall surface of the sleeve. And each sheet-like product can be packed with a sleeve having a relatively small inner dimension so that the gap is 20 mm or less.

  Moreover, as another form of the package, the laminate may be obtained by stacking the sheet-like products for the number of sheets in which the thickness of the laminate is 50 mm or more.

  As the sheet-like products are stacked, the individual sheet-like products are more easily displaced, and the work efficiency of the packaging of the laminate can be deteriorated. On the other hand, in the above configuration, a sleeve is formed by arranging a plurality of sleeve pieces around the laminate from the horizontal direction and connecting the plurality of sleeve pieces instead of covering the sleeve from above the laminate. To do. Therefore, it is not necessary to consider the state of the laminated body when covering the sleeve, and even if the amount of stacked sheet products is increased, it is possible to prevent the working efficiency of packaging of the laminated body from being deteriorated. That is, according to the said structure, even if it laminated | stacks the sheet-like product for the number of sheets in which the thickness of a laminated body becomes 50 mm or more, a laminated body can be packed without deteriorating working efficiency.

  Moreover, as another form of the said package, each said sheet-like product may be solar cell members, such as a solar cell sealing material and a solar cell protective sheet. The adjacent sleeve pieces may be connected by a screw member that is screwed in a direction perpendicular to the overlapped portion of the adjacent sleeve pieces, and the axial length of the screw member is determined by the adjacent sleeve piece. It may be shorter than the total thickness of both pieces.

  In the said structure, members for solar cells, such as a sealing material for solar cells and a protection sheet for solar cells, are included in a package as a sheet-like product. Since this solar cell member is used as a material for a solar cell, it is better to avoid a solvent such as an adhesive from contacting the solar cell member as much as possible. On the other hand, according to the configuration, since the adjacent sleeve pieces are mechanically connected by the screw member, it is possible to avoid the use of a solvent such as an adhesive as much as possible. It is possible to prevent the solvent from coming into contact with the solar cell member.

  In addition, according to this configuration, since the axial length of the screw member is shorter than the total thickness of both adjacent sleeve pieces, the screw member does not protrude inside the package. Therefore, the screw member does not interfere with the solar cell member included in the package, and the screw member can be prevented from scratching the solar cell member.

  Further, the packing method of the present invention includes a step of arranging a laminate obtained by stacking a plurality of sheet-like products cut into a predetermined shape on a bottom cover, and one sleeve piece among the plurality of sleeve pieces. And comprising two side walls respectively extending along two adjacent sides of the laminate, each of the two side walls having a sleeve piece having a length that allows alignment of the respective sheet-like products. The step of aligning the sheet-like products that constitute the laminate, and the remaining sleeve pieces of the plurality of sleeve pieces are arranged around the laminate. Disposing and connecting the plurality of sleeve pieces to each other in the circumferential direction to form a cylindrical sleeve surrounding the laminate, and disposing a canopy on the upper end of the sleeve, Close side opening Provided that the step. According to the said structure, the efficiency of the operation | work which packs the laminated body of a sheet-like product for the same reason as the above can be improved.

  ADVANTAGE OF THE INVENTION According to this invention, the efficiency of the operation | work which packs the laminated body of a sheet-like product can be improved.

The solar cell member 60 corresponds to the “sheet-like product” of the present invention. The solar cell member 60 will be described later. In the present embodiment, the stacked body 6 is circumferentially arranged with the first side 61, the second side 62 adjacent to the first side 61, the first side 61, and the second side 62. The fourth side 64 is opposed to the third side 63 and the first side 61 and is adjacent to the second side 62 and the third side 63. Each side 61-64 of the laminated body 6 respond | corresponds to each side of the member 60 for solar cells (each sheet-like product).

  The package 1 is placed on the pallet 5 after packing such a laminate 6. The pallet 5 is a loading platform for storing and transporting cargo with a forklift or the like. That is, in the present embodiment, the packing body 1 in which the stacked body 6 is packed can be transported via the pallet 5 by a forklift or the like. However, the conveyance method of the package 1 according to the present embodiment is not limited to such an example, and may be appropriately selected according to the embodiment. Hereinafter, each component of such a package 1 is demonstrated.

(Bottom lid)
First, the bottom cover 2 will be described. The bottom lid 2 constitutes the bottom of the package 1 and has a placement surface 23 on which the stacked body 6 is placed. Side walls (21, 22) extending upward are provided on both sides of the mounting surface 23 in the short direction. Both side walls (21, 22) are opposed to the short side direction of the bottom lid 2, and are configured along the longitudinal direction. On the other hand, such side walls are not provided at both ends in the longitudinal direction of the mounting surface 23. That is, the mounting surface 23 is open in the longitudinal direction.

  However, the configuration of the bottom lid 2 is not limited to such an example, and may be appropriately selected according to the embodiment. Moreover, the dimension of the bottom cover 2 can be set suitably according to embodiment. For example, the bottom cover 2 can be formed so that the length in the longitudinal direction is 1690 mm and the length in the lateral direction is 1080 mm. In addition, you may interchange this longitudinal direction and a transversal direction. The bottom lid 2 may be referred to as a tray or a lower lid.

  Such a material of the bottom cover 2 can be appropriately selected according to the embodiment. For example, a paper cardboard can be used as the material of the bottom cover 2. The type of cardboard need not be limited, and may be, for example, an A flute, a B flute, a C flute, or the like. Further, the type of the cardboard layer may be either single, two, or three layers. However, the material of the bottom cover 2 is not limited to such an example, and a plastic cardboard may be used, or a material other than the cardboard such as a plate material may be used.

(sleeve)
Next, the sleeve 3 will be described with further reference to FIGS. 2 and 3. FIG. 2 is a perspective view illustrating the configuration of the sleeve 3 according to this embodiment. FIG. 3 is a plan view illustrating the configuration of the sleeve 3 according to this embodiment. As illustrated in FIGS. 1 to 3, the sleeve 3 according to the present embodiment is configured by two sleeve pieces (31, 33) so as to surround the periphery of the laminate 6 having a rectangular shape in plan view. It is formed in a cylindrical shape.

  The first sleeve piece 31 includes a rectangular first side wall 311, a second side wall 312 connected to one lateral end of the first side wall 311, and a second side connected to the other lateral end of the first side wall 311. 3 side walls 313. As illustrated in FIG. 1, the first side wall 311 has a lateral length longer than the length of the first side 61 of the stacked body 6 to be packed so that the stacked body 6 can be accommodated in the sleeve 3. Have.

  Similarly, the second sleeve piece 33 has a rectangular first side wall 331, a second side wall 332 connected to one end portion in the lateral direction of the first side wall 331, and the other end portion in the lateral direction of the first side wall 331. A third side wall 333 to be connected. The second sleeve piece 33 is disposed to face the first sleeve piece 31. Therefore, the first side wall 331 has a lateral length longer than the length of the fourth side 64 of the stacked body 6 to be packed so that the stacked body 6 can be accommodated in the sleeve 3.

  Further, as illustrated in FIGS. 2 and 3, when the sleeve 3 is formed, the second side wall 312 of the first sleeve piece 31 and the third side wall 333 of the second sleeve piece 33 are formed of the laminate 6. Are connected on the second side 62 side. The third side wall 313 of the first sleeve piece 31 and the second side wall 332 of the second sleeve piece 33 are connected on the third side 63 side of the stacked body 6.

  Therefore, the side wall of the sleeve 3 configured by connecting the second side wall 312 of the first sleeve piece 31 and the third side wall 333 of the second sleeve piece 33 has a lateral direction longer than the length of the second side 62. It is formed to have a length. The side wall of the sleeve 3 configured by connecting the third side wall 313 of the first sleeve piece 31 and the second side wall 332 of the second sleeve piece 33 has a lateral length longer than the length of the third side 63. Is formed.

  Specifically, the second side wall 312 of the first sleeve piece 31 is in contact with the second side 62 of the stacked body 6 so that each solar cell member 60 (sheet-like product) can be aligned. The laminate 6 is formed to have a lateral length longer than half of the length of the second side 62 of the laminate 6. Accordingly, the third side wall 333 of the second sleeve piece 33 is formed to have a lateral length shorter than half of the length of the second side 62 of the stacked body 6.

  Similarly, the second side wall 332 of the second sleeve piece 33 is laminated so that the solar cell members 60 (sheet-like products) can be aligned by bringing the third side 63 of the laminated body 6 into contact with each other. The body 6 is formed to have a lateral length longer than half of the length of the third side 63 of the body 6. Accordingly, the third side wall 313 of the first sleeve piece 31 is formed to have a lateral length that is shorter than half the length of the third side 63 of the stacked body 6.

  Here, “the length that enables positioning of each sheet-like product” of the present invention means that each sheet-like product (laminated body) is brought into contact with the side wall of the sleeve piece to contact each sheet. The length of the product that can be aligned inside the sleeve piece. For example, when each sheet-like product is a substantially uniform sheet, the center of gravity of each sheet-like product is located substantially in the center. Therefore, if the side wall of the sleeve piece has a lateral length longer than half of the length of the side of each sheet-like product, the corresponding side comes into contact with the side wall of the sleeve piece. In addition, the side wall of the sleeve piece can act on the center of gravity of each sheet-like product. That is, the moment of force acting on each sheet-like product from the side wall of the sleeve piece acts in a direction to fit each sheet-like product inside the sleeve piece, thereby aligning each sheet-like product inside the sleeve piece. be able to.

  Accordingly, if the side wall of the sleeve piece has a lateral length longer than half of the length of the side of each sheet-like product, the sheet-like product is brought into contact with the side wall of the sleeve piece. Each sheet-like product can be aligned. Therefore, the length in the lateral direction that is longer than half of the length of the side of each sheet-like product can correspond to “the length that allows alignment of each sheet-like product” in the present invention.

  In the present embodiment, in the first sleeve piece 31, the first side wall 311 and the second side wall 312 have such a length that each solar cell member 60 can be aligned. Similarly, in the 2nd sleeve piece 33, the 1st side wall 331 and the 2nd side wall 332 have the length which can position each member 60 for solar cells. Therefore, both the first sleeve piece 31 and the second sleeve piece 33 correspond to “at least one sleeve piece” of the present invention.

  As illustrated in FIG. 3, in the present embodiment, the end portion of the second side wall 312 of the first sleeve piece 31 is in contact with the inner wall surface of the first side wall 331 of the second sleeve piece 33. Further, the end portion of the second side wall 332 of the second sleeve piece 33 is in contact with the inner wall surface of the first side wall 311 of the first sleeve piece. Therefore, the second side wall 312 of the first sleeve piece 31 has a lateral length longer than the length of the second side 62 of the stacked body 6, and the second side wall 332 of the second sleeve piece 33 is The horizontal length of the laminate 6 is longer than the length of the third side 63 of the laminate 6.

  Moreover, in this embodiment, each member 60 for solar cells which comprises the laminated body 6 is formed in the planar view rectangular shape. Therefore, when the solar cell members 60 are aligned in the vertical direction, the first side edge 61 and the fourth side edge 64 of the stacked body 6 have the same length, and the second side edge 62 and the second side edge The length is the same as the three side edges 63. Therefore, in this embodiment, the 1st sleeve piece 31 and the 2nd sleeve piece 33 are mutually formed in the same shape. However, the shape of the first sleeve piece 31 and the second sleeve piece 33 is not limited to such an example, and may be different from each other.

  Next, the structure of each sleeve piece (31, 33) will be described with further reference to FIGS. FIG. 4 is an exploded perspective view illustrating the configuration of the first sleeve piece 31 (second sleeve piece 33) according to this embodiment. FIG. 5 is a perspective view illustrating the configuration of the first sleeve piece 31 (second sleeve piece 33) according to this embodiment. FIG. 6 is a plan view illustrating the configuration of the first sleeve piece 31 (second sleeve piece 33) according to this embodiment.

  As illustrated in FIGS. 4 to 6, the first sleeve piece 31 according to the present embodiment moves the two plate-shaped members of the first plate-shaped member 321 and the second plate-shaped member 322 in the lateral direction (FIG. 6). Left and right direction) and pasted together. The horizontal length W1 of the first plate member 321 is longer than the horizontal length W2 of the second plate member 322, and the height H1 of the first plate member 321 is the second plate. The length is the same as the height H <b> 2 of the shaped member 322.

The second plate-shaped member 322 corresponds to “one plate-shaped member” of the present invention, and the first plate-shaped member 321 corresponds to “the other plate-shaped member” of the present invention.

  As illustrated in FIG. 6, the second side wall 312 of the first sleeve piece 31 includes an overlapping portion 325 and a first non-overlapping portion 326. Here, the lateral length of the second plate member 322 matches the lateral length of the second side wall 312, and the end of the second plate member 322 is the end of the first plate member 321. The first non-polymerized portion 326 is formed in the second plate-like member 322 by the amount shifted laterally from the portion.

  On the other hand, the first side wall 311 and the third side wall 313 of the first sleeve piece 31 are configured by the second non-overlapping portion 327 in the first plate-like member 321. Specifically, the first plate-like member 321 has a fold line 323 near the end of the second plate-like member 322 on the overlapping portion 325 side, and from the end on the second non-overlapping portion 327 side. The first non-overlapping portion 326 has a fold line 324 on the inner side by the length in the horizontal direction. The first side wall 311 of the first sleeve piece 31 is configured by a region from the fold line 323 to the fold line 324, and the third side wall 313 is configured by a region from the fold line 324 to the end portion on the second non-polymerized portion 327 side. The

  Similarly, the second sleeve piece 33 according to the present embodiment is configured by bonding two plate-like members, a first plate-like member 341 and a second plate-like member 342, while shifting them in the lateral direction. The first plate member 341 corresponds to the first plate member 321, and the second plate member 342 corresponds to the second plate member 322.

  That is, the first plate-like member 341 and the second plate-like member 342 are bonded to each other, so that the overlapping portion 345 where the two plate-like members (341, 342) overlap each other and the second plate-like member 342 in the first plate-like member. A first non-polymerized portion 346 in which 341 does not overlap and a second non-polymerized portion 347 in which the second plate-shaped member 342 does not overlap in the first plate-shaped member 341 are formed.

  Further, the second side wall 332 of the second sleeve piece 33 is composed of a superposed portion 345 and a first non-polymerized portion 346. On the other hand, the first side wall 331 and the third side wall 333 of the second sleeve piece 33 are configured by the second non-polymerized portion 347. Specifically, the first side wall 331 is configured by a region from the fold line 343 to the fold line 344 in the second non-polymerized part 347, and the third side wall 333 is formed from the fold line 344 to the end part in the second non-polymerized part 347. Consists of regions.

  As illustrated in FIG. 3, the second side wall 312 of the first sleeve piece 31 and the third side wall 333 of the second sleeve piece 33 are connected to the first non-overlapping portion 326 of the first sleeve piece 31. This is performed in one region on the end side of the second non-overlapping portion 347 of the second sleeve piece 33. Specifically, the first non-polymerized portion 326 of the first sleeve piece 31 and the region constituting the third side wall 333 in the second non-polymerized portion 347 of the second sleeve piece 33 are connected.

  Here, the first non-polymerized portion 326 of the first sleeve piece 31 and the region constituting the third side wall 333 in the second non-polymerized portion 347 of the second sleeve piece 33 are formed to have the same size. Therefore, by configuring the first plate member 321 of the first sleeve piece 31 and the first plate member 341 of the second sleeve piece 32 with the same thickness, the thickness of the sleeve 3 is uniform on the side where the connection is performed. Can be.

  Similarly, the connection between the third side wall 313 of the first sleeve piece 31 and the second side wall 332 of the second sleeve piece 33 is connected to a region on the end side of the second non-overlapping portion 327 of the first sleeve piece 31 and the second side wall 332. This is performed with the first non-polymerized portion 346 of the two-sleeve piece 33. Specifically, the region constituting the third side wall 313 in the second non-polymerized portion 327 of the first sleeve piece 31 and the first non-polymerized portion 326 of the second sleeve piece 33 are connected. At this time, as described above, the first plate-like member 321 of the first sleeve piece 31 and the first plate-like member 341 of the second sleeve piece 32 are configured with the same thickness, so that on the side where the connection is performed, 3 can be made uniform.

  In addition, the method of connecting the sleeve pieces (31, 33) adjacent to each other can be appropriately selected according to the embodiment. For example, a tape, an adhesive, or the like may be used to connect the sleeve pieces (31, 33) adjacent to each other. However, in the present embodiment, the stacked body 6 to be packed is composed of the solar cell member 60. Since the solar cell member 60 is used as a battery material, it is better to avoid a solvent such as an adhesive from contacting the solar cell member 60 as much as possible.

  Therefore, in the present embodiment, as illustrated in FIGS. 2 and 3, adjacent sleeve pieces (31, 33) are connected by a screw member 36. Therefore, according to the present embodiment, the adjacent sleeve pieces (31, 33) are mechanically connected by the screw member 36, so that the use of a solvent such as an adhesive can be avoided as much as possible. It is possible to prevent the solvent from coming into contact with the solar cell member 60 included in the solar cell 1.

  The screw member 36 is screwed in a direction perpendicular to a portion where adjacent sleeve pieces (31, 33) are overlapped. Here, as illustrated in FIG. 3, the axial length of the screw member 36 is shorter than the total thickness of both the adjacent sleeve pieces (31, 33). Therefore, it can prevent that the screw member 36 protrudes inside the package 1, and this prevents that the screw member 36 damages the solar cell member 60 included in the package 1. be able to. For example, M screw (registered trademark) manufactured by Asakawa Gumi Transportation Co., Ltd. can be used for such a screw member 36.

  Note that the connection between the first plate member 321 and the second plate member 322 and the connection between the first plate member 341 and the second plate member 342 can be similarly performed. That is, the screw member 35 similar to the screw member 36 is used to connect the first plate member 321 and the second plate member 322 and to connect the first plate member 341 and the second plate member 342. Also good. Moreover, a tape, an adhesive agent, etc. may be used for these connections.

  The sleeve 3 is configured as described above. The dimension of this sleeve 3 can be suitably set according to the dimension of the laminated body 6 (each solar cell member 60) to be packed. Moreover, the material of each sleeve piece (31, 33), in other words, the material of each plate-like member (321, 322, 341, 342) can be appropriately selected according to the embodiment. For example, as the material of each plate-like member (321, 322, 341, 342), cardboard made of paper, plastic, or the like may be used as in the case of the bottom cover 2, or a material other than cardboard is used. May be. As described above, the type of cardboard to be used is not limited, and may be, for example, an A flute, a B flute, a C flute, or the like. The type of the corrugated cardboard layer to be used may be either single, two, or three layers. In addition, a different material may be used for both sleeve pieces (31, 33), and a material different from the said bottom cover 2 may be used.

(canopy)
Next, the canopy 4 will be described. The canopy 4 is formed in a flat rectangular parallelepiped shape. Specifically, a side wall is provided at each end of the canopy 4, and the inner dimension of the space surrounded by each side wall corresponds to the outer shape of the sleeve 3. Therefore, the opening on the upper end side of the sleeve 3 can be closed by the canopy 4. The canopy 4 may be referred to as a cap, an upper lid, or the like.

  The material of such a canopy 4 can be appropriately selected according to the embodiment, like the bottom lid 2 and the sleeve 3. For example, the material of the canopy 4 may be a cardboard made of paper or plastic, or a material other than the cardboard may be used. The canopy 4 may be made of a material different from at least one of the bottom lid 2 and the sleeve 3.

<Laminated body>
Next, the laminated body 6 packed by the packing body 1 is demonstrated. As illustrated in FIG. 1, in the present embodiment, the laminate 6 is obtained by stacking a plurality of sheet-like solar cell members 60 cut into a rectangular shape in plan view.

  As described above, the solar cell member 60 corresponds to the “sheet-like product” of the present invention. However, the sheet-like product constituting the laminated body 6 is not limited to such an example, and may be appropriately selected according to the embodiment. Moreover, the shape of the member 60 for solar cells may not be restricted to a rectangular shape in plan view, and may be appropriately selected according to the embodiment. For example, the solar cell member 60 may have a predetermined shape such as a polygonal shape, a circular shape, or an elliptical shape. The “rectangular shape in plan view” includes a square shape.

  The solar cell member 60 is, for example, a solar cell sealing material, a solar cell protective sheet, or the like. The sealing material for solar cells is a sheet-like packaging material for sealing battery elements, such as an electrode and an electrolyte, in a solar cell, for example. Moreover, the protective sheet for solar cells is a sheet material for protecting the solar cell module, and is used, for example, on the back surface of the solar cell module. Such a solar cell member 60 may condense when placed in a high humidity environment, and is required to have moisture resistance during storage and transportation. Hereinafter, an example of the configuration of the solar cell member 60 will be described with reference to FIG.

  FIG. 7 illustrates the configuration of the solar cell member 60 when the solar cell member 60 is a solar cell protective sheet. As illustrated in FIG. 7, in the solar cell member 60 according to the present embodiment, a weather-resistant base material 601, an intermediate layer base material 602, and an inner layer base material 603 are interposed via an adhesive layer 604 and an adhesive layer 605. It is a laminated body having a joined three-layer structure.

(Weather-resistant substrate)
The weather-resistant substrate 601 is configured to satisfy the physical properties required for the solar cell member 60 and to have excellent hydrolysis resistance among materials used for the solar cell module laminated member.

  Examples of the material of the weather resistant substrate 601 include polyethylene resin, polypropylene resin, cyclic polyolefin resin, polystyrene resin, acrylonitrile-styrene copolymer, acrylonitrile-butadiene-styrene copolymer, polychlorinated resin, and the like. Vinyl resins, fluorine resins, poly (meth) acrylic resins, polycarbonate resins, polyester resins such as polyethylene terephthalate and polyethylene naphthalate, polyamide resins such as various nylons, polyimide resins, polyamideimide resins, Film materials or sheet materials such as polyaryl phthalate resins, silicone resins, polysulfone resins, polyphenylene sulfide resins, polyether sulfone resins, polyurethane resins, acetal resins, and cellulose resins It can be used.

  The weather-resistant substrate 601 can be produced by using one or a plurality of resins among the above-described resins by an extrusion method, a cast molding method, a T-die method, a cutting method, an inflation method, or other film forming methods. . The thickness of the weather-resistant substrate 601 is not particularly limited, but is preferably 5 to 250 μm, more preferably 10 to 150 μm from the viewpoint of transportability during processing, and 20 to 80 μm. Most preferably. The weather resistant substrate 601 may be subjected to a surface treatment for improving adhesion with other substrates.

(Intermediate layer base material)
The intermediate layer base material 602 has a role as a layer between the weather resistant base material 601 and the inner layer base material 603, and is disposed from the viewpoints of insulation, ensuring strength, water vapor barrier properties, and the like. As the material of the intermediate layer base material 602, a metal foil such as polyethylene terephthalate, polyethylene naphthalate, polybutylene terephthalate, and aluminum foil can be used.

  In addition, the intermediate layer base material 602 can be manufactured by a known film forming method, similarly to the weather resistant base material 601. The intermediate layer base material 602 may be composed of a single layer or a plurality of layers. In addition, when the intermediate | middle layer base material 602 is comprised with a some layer, each layer can be joined with an adhesive agent. The thickness of such an intermediate layer base material 602 is not particularly limited, but is preferably 12 to 250 μm from the viewpoint of ensuring the mechanical strength and ensuring the workability.

  When a resin film is used as the intermediate layer base material 602, a metal oxide vapor deposition film may be provided on the surface of the weather resistant base material 601. By providing such a metal oxide vapor deposition film, moisture resistance, weather resistance, and the like can be imparted to the weather resistant substrate 601. In addition, the method of forming a metal oxide vapor deposition film on the surface of the weather resistant base material 601 is not particularly limited, and may be a known vapor deposition method. For example, physical vapor deposition such as vacuum deposition, sputtering, ion plating, ion cluster beam, or chemical vapor deposition such as plasma chemical vapor deposition, thermal chemical vapor deposition, and photochemical vapor deposition Thus, a metal oxide vapor deposition film may be formed on the surface of the weather resistant substrate 601.

  Moreover, the kind of metal oxide vapor deposition film may be suitably selected according to embodiment. Examples of the metal constituting the deposited film include silicon (Si), aluminum (Al), magnesium (Mg), calcium (Ca), potassium (K), tin (Sn), sodium (Na), boron (B), Titanium (Ti), lead (Pb), zirconium (Zr), yttrium (Y), or the like may be used. The thickness of such a metal oxide vapor-deposited film is not particularly limited, but from the viewpoint of imparting moisture resistance and weather resistance, and suppressing the occurrence of cracking or cracking of the metal oxide vapor-deposited film, 100 nm is preferable, and 10 to 60 nm is more preferable.

(Inner layer base material)
The inner layer base material 603 is in contact with the filler constituting the solar cell module. For this reason, selection of the material used for the inner-layer base material 603 can be performed in consideration of adhesion to the filler, for example. When a polyolefin-based filler is used in the solar cell module, it is preferable to use polyethylene as the material of the inner layer base material 603. Polyethylene has high adhesion to polyolefin-based fillers, and the combination of these materials contributes to improving the durability of the laminated member for solar cell modules. The material used for the inner layer base material 603 may contain other materials. Further, the inner layer base material 603 may contain various additives such as those contained in the weather resistant base material 601.

  This inner layer base material 603 can be produced by a known film forming method, similarly to the weather resistant base material 601 and the intermediate layer base material 602. The thickness of the inner layer base material 603 is not particularly limited, but is preferably 15 to 250 μm from the viewpoint of securing the mechanical suitability while ensuring the mechanical strength. In addition, the inner layer base material 603 may be subjected to a surface treatment for improving adhesion to other base materials in the same manner as the weather resistant base material 601. Furthermore, a metal oxide film and a metal foil may be provided on the inner layer base material 603 by a known method in order to improve the barrier property and the like.

(Production method)
Such a solar cell member 60 can be appropriately manufactured according to the embodiment. For example, the solar cell member 60 can be produced by providing each adhesive layer (604, 605) between the base materials 601 to 603 and performing dry lamination. For each adhesive layer (604, 605), a two-component adhesive composed of a main agent and a curing agent can be used.

(Other)
In the present embodiment, the solar cell member 60 is configured as described above. However, the configuration of the solar cell member 60 is not limited to such an example, and may be appropriately selected according to the embodiment.

  Moreover, the planar dimension of each member 60 for solar cells may be set suitably according to embodiment. For example, each solar cell member 60 may be formed such that at least one of the four sides is 800 mm or more. As a specific example, the length of the first side edge 61 and the fourth side edge 64 can be 980 mm, and the length of the second side edge 62 and the third side edge 63 can be 1660 mm.

  In addition, in this embodiment, since each solar cell member 60 is formed in a rectangular shape, the first side edge 61 and the fourth side edge 64 have the same length, and the second side edge 62 and the third side edge 60 are the same. The side edges 63 have the same length. In addition, as described above, the second side edge 62 and the third side edge 63 are longer than the first side edge 61 and the fourth side edge 64. However, the relationship between the lengths of the sides 61 to 64 is not limited to such an example, and may be appropriately selected according to the embodiment. For example, the lengths of the first side edge 61 and the fourth side edge 64 and the lengths of the second side edge 62 and the third side edge 63 may be interchanged.

  Furthermore, the thickness of each solar cell member 60 may be appropriately set according to the embodiment. For example, the thickness of each solar cell member 60 may be set to be 0.5 mm or less. The laminate 6 is configured by stacking a plurality of such solar cell members 60. At this time, the laminated body 6 may be obtained by stacking the solar cell members 60 for the number of sheets in which the thickness of the laminated body 6 (length in the vertical direction in FIG. 1) is 50 mm or more. For example, a large number of solar cell members 60 may be stacked, and the thickness of the stacked body 6 may be 380 mm.

§2 usage method Next, the usage method of the package 1 which concerns on this embodiment is demonstrated using FIGS. 8-12. 8-12 illustrates the process of packing the laminated body 6 with the packing body 1 which concerns on this embodiment. In addition, the usage method of the package 1 demonstrated below is corresponded to the "packing method" of this invention. However, the procedure described below is only an example, and each step may be changed as much as possible. In addition, in the procedure described below, processes can be omitted, replaced, and added as appropriate according to the embodiment.

(First step)
First, as illustrated in FIG. 8, as a first step, a laminate 6 obtained by stacking a plurality of sheet-like solar cell members 60 cut into a rectangular shape in plan view is prepared, The laminated body 6 is disposed on the bottom lid 2 disposed in (1). At this time, the thickness of the laminated body 6 can be 380 mm.

(Second step)
Next, as illustrated in FIG. 9, as the second step, one of the two sleeve pieces (31, 33) constituting the sleeve 3 is arranged so as to contact the side of the laminated body 6. The solar cell member 60 constituting the laminate 6 is aligned. In the present embodiment, since both the first sleeve piece 31 and the second sleeve piece 33 have two side walls having a length capable of aligning the solar cell member 60, the first sleeve piece 31 and the second sleeve piece 33 are provided. Either of the sleeve pieces 33 may be used for alignment.

  For example, as illustrated in FIGS. 9 and 10, the first sleeve piece 31 is brought close to the stacked body 6 from the first side 61 side, and the first side wall 311 and the second side wall 312 of the first sleeve piece 31 are formed. The first sleeve piece 31 is disposed around the stacked body 6 so as to contact the first side edge 61 and the second side edge 62 of the stacked body 6. At this time, since the end side of the bottom cover 2 is released in the longitudinal direction, the first sleeve piece 31 can be disposed around the stacked body 6 from the released region. In the second step, the laminated body 6 is brought together with the first sleeve piece 31 toward the side wall 21 of the bottom cover 2 so that the second sleeve piece 33 described later can be easily arranged.

(Third step)
Next, as illustrated in FIG. 10, as the third step, the remaining sleeve pieces excluding the sleeve pieces arranged in the second step are arranged around the laminated body 6, and both sleeve pieces (31, 33) are arranged. Are connected to each other in the circumferential direction to form a rectangular tube-like sleeve 3 surrounding the periphery of the laminate 6.

  In the example of FIG. 10, since the first sleeve piece 31 is arranged around the laminated body 6 in the second step, the second sleeve piece 33 is arranged around the laminated body 6 in the third step. Specifically, the second sleeve piece 33 is brought close to the laminated body 6 from the fourth side 64 side, and the second sleeve piece 33 is arranged around the laminated body 6. At this time, as described above, since the end side of the bottom cover 2 is released in the longitudinal direction as described above, the second sleeve piece 33 can be disposed around the stacked body 6 from the released region. it can.

  Then, the overlapping portions of the second side wall 312 of the first sleeve piece 31 and the third side wall 333 of the second sleeve piece 33 are connected by the screw member 36. Further, the overlapping portion of the third side wall 313 of the first sleeve piece 31 and the second side wall 332 of the second sleeve piece 33 is connected by the screw member 36. As a result, the sleeve pieces (31, 33) are connected to each other in the circumferential direction, and the sleeve 3 in a state of being already arranged around the laminated body 6 is formed.

  Here, each sleeve piece (31, 33) can be dimensioned such that the gap between the inner wall surface of the sleeve 3 and each solar cell member 60 is 20 mm or less. For example, as described above, when the planar dimension of the laminate 6 is 980 mm (short direction) × 1660 mm (longitudinal direction), each sleeve piece (31, 31) is set so that the inner dimension of the sleeve 3 is 1000 mm × 1667 mm. 33) can be dimensioned. Further, when the height of the laminated body 6 is 380 mm, the height of each sleeve piece (31, 33), in other words, the height of the sleeve 3 may be 380 mm or more. The thickness can be 420 mm.

  In addition, in FIG. 10, the scene which has arrange | positioned the 1st sleeve piece 31 and the 2nd sleeve piece 33 separately is illustrated. However, instead of arranging only one of them, both sleeve pieces (31, 33) may be arranged around the laminate 6 at a time. That is, the arrangement of the sleeves in the second step and the arrangement of the sleeve pieces in the third step may be performed simultaneously.

(4th process)
Finally, as illustrated in FIGS. 11 and 12, as the fourth step, the top cover 4 is disposed at the upper end of the sleeve 3 to close the opening on the upper end side of the sleeve 3. Thereby, packing of the laminated body 6 by the packing body 1 is completed. Note that simply placing the canopy 4 on the upper end of the sleeve 3 may cause the canopy 4 to come off the upper end of the sleeve 3. Therefore, as illustrated in FIG. 12, after placing the canopy 4 on the upper end of the sleeve 3, the packing body 1 may be fastened and fixed together with the pallet 5 using one or a plurality of bands 51.

[Action / Effect]
As described above, in the present embodiment, the sleeve 3 surrounding the laminate 6 is divided into two sleeve pieces (31, 33). Therefore, as shown in the second step and the third step, the sleeve 3 is not put on the laminated body 6 but two sleeve pieces (31, 33) are arranged around the laminated body 6 from the horizontal direction. Thus, the arrangement of the sleeve 3 can be completed by connecting both the sleeve pieces (31, 33). Therefore, according to the present embodiment, since the operation step of covering the sleeve 3 from the top of the laminate 6 is released, it is not necessary to consider the state of the laminate 6 when the sleeve 3 is arranged. The laminated body 6 can be packed without being affected by physical interference of the solar cell member 60.

  In addition, in the present embodiment, the first side wall 311 and the second side wall 312 of the first sleeve piece 31 and / or the first side wall 331 and the second side wall 332 of the second sleeve piece 33 are respectively the solar cell member 60. It has a length that can be aligned. Specifically, each side wall (311, 312, 331, 332) has a lateral length longer than the corresponding side of the solar cell member 60. Therefore, even when the individual solar cell members 60 are slightly displaced, as shown in the second step and the third step, when assembling the sleeve pieces (31, 33), the sleeve pieces (31, 33) are assembled. ) Can be positioned around the laminate 6 to align the individual solar cell members 60. That is, according to each sleeve piece (31, 33), it is possible to align the solar cell members 60 in the vertical direction so as not to interfere with the packing of the stacked body 6 without increasing the working efficiency. Therefore, according to this embodiment, the efficiency of the operation | work which packs the laminated body 6 of a sheet-like product can be improved.

  In particular, in this embodiment, both the sleeve pieces (31, 33) can be used for alignment of the solar cell members 60. Therefore, in forming the sleeve 3 in the second step and the third step, the sleeve pieces (31, 33) are brought close to the laminated body 6 from the opposing direction when the sleeve pieces (31, 33) are made to face each other. Can be arranged around the laminate 6 and the solar cell members 60 can be naturally aligned. Therefore, according to this embodiment, the efficiency of the operation | work which packages the laminated body 6 of a sheet-like product can be improved especially.

  In the present embodiment, the first sleeve piece 31 and the second sleeve piece 33 are formed in the same shape. For this reason, the first sleeve piece 31 and the second sleeve piece 33 do not have to be manufactured separately, so that the number of parts can be reduced and the efficiency of manufacturing both sleeve pieces (31, 33) is increased. Therefore, according to this embodiment, the manufacturing cost of the package 1 can be suppressed.

  Moreover, in this embodiment, the 1st sleeve piece 31 can be produced in the simple process of shifting and bonding two plate-shaped members (321,322) to a horizontal direction. Similarly, the second sleeve piece 33 can be manufactured by a simple process in which two plate-like members (341, 342) are bonded while being shifted in the horizontal direction. Therefore, according to this embodiment, the manufacturing cost of the package 1 can be suppressed.

  Moreover, in this embodiment, the thickness of the sleeve 3 can be made uniform in the area | region which connects both the sleeve pieces (31, 33). Therefore, it is possible to prevent stress from being easily applied to a part of the package 1, and the strength of the package 1 is relatively low despite the simple configuration in which the plate-like members are simply bonded together. Can be increased.

  In the present embodiment, the length of at least one of the four sides of the solar cell member 60 can be 800 mm or more, and the thickness of the solar cell member 60 can be 0.5 mm or less. In addition, each sleeve piece (31, 33) can be dimensioned such that the gap between the inner wall surface of the sleeve 3 and each solar cell member 60 is 20 mm or less. Furthermore, the solar cell members 60 corresponding to the number of the laminated bodies 6 having a thickness of 50 mm or more can be stacked. Conventionally, it is difficult to cover the laminated body 6 with a sleeve, and the packaging work efficiency is deteriorated. On the other hand, in this embodiment, since the divided two sleeve pieces (31, 33) are arranged from the periphery of the laminated body 6, the work efficiency is deteriorated even in the above situation. And the laminated body 6 can be packed.

§3 Modifications While the embodiment of the present invention has been described above, the above description is merely an example of the present invention in all respects. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention. In addition, regarding each component of the package 1, the component may be omitted, replaced, and added as appropriate according to the embodiment. The shape and size of each component of the package 1 may be set as appropriate according to the embodiment. For example, the following changes can be made. In the modification described below, the same reference numerals are used for the same components as those in the above embodiment, and the description thereof is omitted as appropriate.

However, the number of sleeve pieces constituting the sleeve 3 is not limited to two, and may be three or more. In this case, at least one sleeve piece has two side walls that respectively extend along two adjacent sides of the laminate 6, such as the first side wall (311, 331) and the second side wall (312, 332). Each of the two side walls is configured to have such a length that each sheet-like product (solar cell member 60) can be aligned. For example, an example as shown in FIG. 13 can be given.

  FIG. 13 is an exploded perspective view illustrating a package 1a according to this modification. In the package 1 a of the modified example illustrated in FIG. 13, the sleeve 3 a is composed of four sleeve pieces, a first sleeve piece 31 a, a second sleeve piece 33 a, a third sleeve piece 38, and a fourth sleeve piece 39. ing. In the package 1a of the present modification, the total length of the second side wall 312a of the first sleeve piece 31a and the third side wall 333a of the second sleeve piece 33a is shorter than the second side 62 of the stacked body 6. ing. Therefore, in this modification, the third sleeve piece 38 is disposed between the second side wall 312a of the first sleeve piece 31a and the third side wall 333a of the second sleeve piece 33a. Thus, the sleeve 3 a is configured such that the length of the side wall on the second side 62 side is longer than the length of the second side 62 of the multilayer body 6. Similarly, the sleeve 3a is configured such that the fourth sleeve piece 39 is disposed between the third side wall 313a of the first sleeve piece 31a and the second side wall 332a of the second sleeve piece 33a, so that The length of the side wall is configured to be longer than the length of the third side 63 of the stacked body 6.

However, the shape of each solar cell member 60 may not be limited to such an example, and may be appropriately selected according to the embodiment. For example, an example as shown in FIG. 14 can be given.

  FIG. 14 is an exploded perspective view illustrating a package 1b according to this modification. In the package 1b of the modified example illustrated in FIG. 14, each solar cell member 60b constituting the stacked body 6b is cut into a hexagon in plan view. Correspondingly, the bottom lid 2b and the canopy 4b are also formed in a hexagonal shape. Furthermore, the first sleeve piece 31b and the second sleeve piece 33b constituting the sleeve 3b are formed to have a hexagonal shape when connected to each other. In this case, each solar cell member 60b may be configured such that at least one of the diagonals L is 800 mm or more.
