[0004] [Patent Document 1] JP 2005-153888 A Summary of the Invention [Problem to be solved by the invention]
[0005] In the patent document 1, it is difficult to remove the solar cell panel from the front side or the top side of the package.
[0006] In view of the above circumstances, an object of the present disclosure is to provide a solar cell module packaging body, a solar cell module packaging structure, and a method for unpacking the solar cell module packaging structure that can increase the work efficiency when removing the solar cell module. [Means for solving the problem]
[0007] Configuration 1 of the present disclosure is a packaging body that encases a hexahedron consisting of a solar cell module group formed by vertically arranging a plurality of solar cell modules in a front-to-rear direction, the front surface and rear surface of the hexahedron being respectively constituted by a surface of a solar cell module arranged at the front and rear of the solar cell module group, the left surface and right surface of the hexahedron being respectively constituted by left end surfaces and right end surfaces of the plurality of solar cell modules forming the solar cell module group, the top surface of the hexahedron and the bottom surface of the hexahedron being respectively constituted by a surface of a solar cell module arranged at the rear of the solar cell module group, Each surface is composed of upper and lower end surfaces of a plurality of the solar cell modules that form the solar cell module group, and comprises a front panel covering the front surface of the hexahedron, a rear panel covering the rear surface of the hexahedron, a left panel covering the left surface of the hexahedron, a right panel covering the right surface of the hexahedron, a top panel covering the top surface of the hexahedron, and a bottom panel covering the bottom surface of the hexahedron, and is characterized in that the left panel and the right panel each have cutouts that expose the upper left corners and upper right corners of one or more solar cell modules that are positioned in the front of the solar cell module group.
[0008] Here, the solar cell module generally refers to a panel-shaped one that receives sunlight and generates electrical energy, and is also called a solar cell panel, a solar panel, a solar panel, etc. In such a solar cell module, the surface refers to the wide surface that receives sunlight, the left end surface and the right end surface refer to the left and right narrow surfaces when the solar cell module is placed vertically, the top end surface refers to the upper narrow surface when the solar cell module is placed vertically, and the bottom end surface refers to the lower narrow surface when the solar cell module is placed vertically.

[0014] A fifth aspect of the present disclosure may be a packaging body according to the fourth aspect of the present disclosure, wherein an upper part and a lower part of the front panel are configured to be separable from each other.
[0015] Furthermore, configuration 6 of the present disclosure can be a configuration in which, in the packaging body of configuration 5 of the present disclosure, a horizontal winding band is provided that restrains the lower part of the front panel, the left side panel, the rear panel, and the right side panel, and is wrapped around a central axis line along the vertical direction of the hexahedron.
[0016] In addition, configuration 7 of the present disclosure may be configured such that, in the packaging body of configuration 4 of the present disclosure, the front panel, the rear panel, the left panel and the right panel are formed in a rectangular cylindrical shape, and the upper and lower parts of the front panel are configured to be detachable.
[0017] Furthermore, configuration 8 of the present disclosure is a solar cell module packaging structure in which a hexahedron consisting of a group of solar cell modules formed by placing a plurality of solar cell modules vertically and arranging them in the front-to-back direction is wrapped in a packaging body, and is characterized in that the packaging body has the configuration described in any one of configurations 1 to 3 of the present disclosure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0022] Best modes for carrying out the present disclosure will be described with reference to the drawings.
[0023] (Embodiment 1) 1 to 5A-E show embodiment 1 of the present disclosure. A hexahedron 17 is a solar cell module group formed by placing a plurality of solar cell modules 1 vertically and arranging them horizontally. The solar cell module group forming the hexahedron 17 is in a state where the plurality of solar cell modules 1 are restrained in an inseparable manner by a plurality of (for example, four) inner bands 18 so as not to come apart. A packaging body 2 is for wrapping the hexahedron 17.
[0024] The solar cell module 1 is large in size. Here, large size refers to, for example, a width of 1600 mm to 2300 mm, a length of 980 mm to 1200 mm, a weight of 18 kg to 24 kg for a single-sided glass type, and a weight of 28 kg to 33 kg or more for a laminated glass type.
[0025] 5C , in the solar cell module 1, the front surface is labeled with the reference numeral 11, the rear surface is labeled with the reference numeral 12, the left end surface is labeled with the reference numeral 13, the right end surface is labeled with the reference numeral 14, the top end surface is labeled with the reference numeral 15, and the bottom end surface is labeled with the reference numeral 16. The front and rear surfaces are all surfaces of the solar cell module 1. The left end surface, right end surface, top end surface, and bottom end surface are all side surfaces of the solar cell module 1.
[0026] 5B and 5C, the front surface of hexahedron 17 and the rear surface of hexahedron 17 are respectively composed of the surface (front surface 11) of the solar cell module arranged at the front and the surface (rear surface 12) of the solar cell module arranged at the rear of the solar cell module group forming hexahedron 17. Here, the front and rear of solar cell module 1 may be reversed, so that the front surface of hexahedron 17 and the rear surface of hexahedron 17 are respectively composed of the front surface 11 or rear surface 12 of the solar cell module arranged at the front and the rear surface 12 or front surface 11 of the solar cell module arranged at the rear of the solar cell module group forming hexahedron 17.
[0027] The left and right faces of hexahedron 17 are respectively constituted by left end faces 13 and right end faces 14 of the multiple solar cell modules 1 that form the solar cell module group. In other words, the side face of the solar cell module 1 that constitutes the left face of hexahedron 17 is left end face 13, and the side face of the solar cell module 1 that constitutes the right face of hexahedron 17 is right end face 14.
[0028] Moreover, the upper surface and the lower surface of hexahedron 17 are respectively constituted by upper end surfaces 15 and lower end surfaces 16 of the multiple solar cell modules 1 that form the solar cell module group. In other words, the side surface of the solar cell module 1 that constitutes the upper surface of hexahedron 17 is upper end surface 15, and the side surface of the solar cell module 1 that constitutes the lower surface of hexahedron 17 is lower end surface 16.
[0029] Furthermore, as shown in FIG. 2, the structure in which the hexahedron 17 of the solar cell module 1 is packed in the packaging body 2 (solar cell module packaging structure) is placed on a pallet 8, so that it can be easily transported by a forklift or the like, although not shown.
[0030] The packaging body 2 includes a top plate disposed on the top surface of the hexahedron 17, a bottom plate disposed on the bottom surface of the hexahedron 17, a front plate disposed on the front surface of the hexahedron 17, a rear plate disposed on the rear surface of the hexahedron 17, a left plate disposed on the left surface of the hexahedron 17, and a right plate disposed on the right surface of the hexahedron 17. The top plate, bottom plate, front plate, rear plate, left plate, and right plate may each be separate members, or may be integrally formed members. In addition, for example, the top plate and the front plate may be integrally formed members disposed across multiple surfaces of the hexahedron 17. As shown in FIG. 1 and FIG. 2, in the first embodiment, the packaging body 2 includes a side plate 3, a top plate 4, a bottom plate 5, first to fourth vertically wound outer bands 6A to 6D, and first and second horizontally wound outer bands 6E and 6F. The side plate 3 of the packaging body 2 of the first embodiment includes a left plate (a left surface 31 described below), a right plate (a right surface 32 described below), and a rear plate (a rear surface 33 described below), and the top plate 4 includes a front plate (a hanging surface 42 described below). The side plate 3, the top plate 4, and the bottom plate 5 of the packaging body 2 are made of, for example, cardboard.
[0031] 1 and 3, side plate 3 is formed in a U-shape in plan view so as to surround a total of three faces of hexahedron 17, namely, the left face, right face, and rear face, and includes a left face 31, a right face 32, and a rear face 33. Left face 31 is the left side plate, right face 32 is the right side plate, and rear face 33 is the rear plate.
[0032] The left surface 31 of the side plate 3 refers to the surface covering each left end surface 13 (corresponding to the left surface of the hexahedron 17) of the solar cell module 1. The right surface 32 of the side plate 3 refers to the surface covering each right end surface 14 (corresponding to the right surface of the hexahedron 17) of the solar cell module 1. The rear surface 33 of the side plate 3 refers to the surface covering the rear surface 12 (corresponding to the rear surface of the hexahedron 17) of the rear solar cell module 1.
[0033] As shown in FIG. 3, flaps 35 are provided on the lower edges of the left face 31, right face 32 and rear face 33 of the side panel 3.
[0034] 1 and 4, the top plate 4 has a top surface 41 and a hanging surface 42. The top surface 41 is a surface that covers each upper end surface 15 (corresponding to the upper surface of the hexahedron 17) of the group of solar cell modules 1, and the hanging surface 42 is a surface that covers the front surface 11 of the leading solar cell module 1, and is provided so as to hang downward at a right angle to the front edge of the top surface 41. The top surface 41 is a top plate, and the hanging surface 42 is a front plate.
[0035] As shown in FIG. 4, the table top 4 is provided with flaps 43 on the left, right and rear sides of the top surface 41 and on the left and right sides of the hanging surface .
[0036] As shown in FIG. 1, the bottom plate 5 covers the lower end faces 16 (corresponding to the lower faces of the hexahedrons 17) of the solar cell modules 1.
[0037] As shown in FIG. 2, the first to fourth vertically wound outer bands 6A to 6D and the first and second horizontally wound outer bands 6E, 6F bind the side plate 3, the top plate 4 and the bottom plate 5 together so that they cannot be separated.
[0038] The first and second vertically wound outer bands 6A, 6B are wound around a central axis along the left-right direction of the hexahedron 17 so as to extend from the hanging surface 42 of the top plate 4 through the top surface 41 of the top plate 4 to the rear surface 33 of the side plate 3, and from the rear surface 33 through the bottom plate 5 to the hanging surface 42 of the top plate 4. The first and second vertically wound outer bands 6A, 6B are spaced apart in the left-right direction of the hexahedron 17.
[0039] The third and fourth vertically wound outer bands 6C, 6D are wound around a central axis along the front-rear direction of the hexahedron 17 so as to extend from the top surface 41 of the top plate 4 through the left surface 31 of the side plate 3 to the bottom plate 5, and from the bottom plate 5 through the right surface 32 of the side plate 3 to the top surface 41 of the top plate 4. The third and fourth vertically wound outer bands 6C, 6D are spaced apart in the front-rear direction of the hexahedron 17.
[0040] The first and second horizontally wound outer bands 6E, 6F are wound around a central axis along the vertical direction of the hexahedron 17 so as to extend from the hanging surface 42 of the top plate 4 through the left surface 31 of the side plate 3 to the rear surface 33, and from the rear surface 33 through the right surface 32 to the hanging surface 42 of the top plate 4. The first and second horizontally wound outer bands 6E, 6F are spaced apart in the vertical direction of the hexahedron 17.
[0041] Corner pads 7 are provided at each corner of each of the outer bands 6A to 6F to prevent the tightening load from each of the outer bands 6A to 6F from concentrating on a specific area of the solar cell modules 1. The material of each corner pad 7 may be, for example, cardboard.
[0042] 1 and 3, a notch (referred to as a left notch) 36 is provided in the upper front portion of each left surface 31 of side panel 3. A notch (referred to as a right notch) 37 is provided in the upper front portion of each right surface 32 of side panel 3. Due to left notch 36 and right notch 37, both left surface 31 and right surface 32 are pentagonal in front view.
[0043] As shown in FIG. 5B, the cutout shape is a right-angled triangle when viewed from the front. The left cutout 36 exposes the upper left corner of each of the predetermined number of solar cell modules 1. The right cutout 37 exposes the upper right corner of each of the predetermined number of solar cell modules 1. The left cutout 36 and the right cutout 37 do not cover the front upper portion of the left and right faces of the hexahedron 17, and expose the upper left and upper right corners of the predetermined number of solar cell modules 1 arranged at the front among the multiple solar cell modules 1 forming the solar cell module group. The number of solar cell modules 1 whose upper left and upper right corners are exposed is at least one, but if there are five or more, it becomes easier to remove them.
[0044] 1 and 3, starting position 36a of left cutout 36 is set at the midpoint in the front-to-rear direction of the upper edge of left surface 31 of side panel 3. End position 36b of left cutout 36 is set at the midpoint in the up-to-down direction of the front edge of left surface 31 of side panel 3. By setting starting position 36a and end position 36b at the midpoint in the front-to-rear direction and the up-to-down direction in this manner, the upper left corners and upper right corners of a predetermined number of solar cell modules 1 can be exposed while maintaining the strength of left surface 31 of side panel 3.
[0045] Further, starting position 37a of right cutout 37 is set at the midpoint in the front-to-rear direction of the upper edge of right surface 32 of side panel 3. End position 37b of right cutout 37 is set at the midpoint in the up-to-down direction of the front edge of right surface 32 of side panel 3. By setting starting position 37a and end position 37b at the midpoint in the front-to-rear direction and the up-to-down direction in this manner, the upper left corners and upper right corners of a predetermined number of solar cell modules 1 can be exposed while maintaining the strength of right surface 32 of side panel 3.
[0046] 1 and 4, a perforation (called a front perforation) 44 is provided in the vertical center of the hanging surface 42 of the top panel 4. The hanging surface 42 (front panel) is configured so that the upper and lower parts can be separated by this front perforation 44. This front perforation 44 is a horizontal straight line connecting the terminal position 36b of the left cutout 36 and the terminal position 37b of the right cutout 37.
[0047] Next, a method for unpacking the above-mentioned packaging structure for the solar cell module will be described with reference to Figs. 5A to 5E.
[0048] In the packaging structure of the solar cell module 1 shown in FIG. 2, as shown in FIG. 5A, the first to fourth vertically wound outer bands 6A to 6D and the corner pads 7 at the upper corners of the first to fourth vertically wound outer bands 6A to 6D are removed, and the first and second horizontally wound outer bands 6E, 6F are left, and the corner pads 7 at the lateral corners of the first and second horizontally wound outer bands 6E, 6F are pulled out, thereby loosening the first and second horizontally wound outer bands 6E, 6F.
[0049] Thereafter, as shown in FIG. 5B, the portion above the front perforation 44 on the hanging surface 42 of the top plate 4 is cut off, and the top plate 4 is removed.
[0050] As a result, the upper region of the hanging surface 42 is cut out, exposing the upper region of the front surface of the leading solar cell module 1 from the cut out region. The cut out region is continuous with the left and right cutouts 36, 37 of the side panel 3.
[0051] From the left and right cutouts 36, 37, the upper left corners and upper right corners of a predetermined number of solar cell modules 1 located toward the front are exposed.
[0052] By the way, by cutting off the upper region of the hanging surface 42, the lower region of the hanging surface 42 remains. However, the left and right flaps 43 of the remaining lower region (called the remaining portion 42a) are overlapped on the outside of the left surface 31 and right surface 32 of the side panel 3, and the first and second horizontal winding bands 6E, 6F are not cut, so that the remaining portion 42a of the hanging surface 42 does not fall inward.
[0053] Also, the inner band 18 of the hexahedron 17 is cut. This allows the worker to grasp the upper left and upper right corners of the leading solar cell module 1 with his or her hands and remove it upward, as shown in Fig. 5C. Note that the first and second horizontal winding bands 6E, 6F are loosened by removing the corner pads 7 at the lateral corners of the first and second horizontal winding bands 6E, 6F, making it easier to remove the solar cell module 1.
[0054] Moreover, when removing the solar cell module 1, it is only necessary to lift the solar cell module 1 above the remaining portion 42a of the hanging surface 42, so the labor required by the worker can be reduced compared to the case where a large solar cell module 1 is lifted higher than the upper end surface 15 of another large solar cell module 1. In other words, the height of the remaining portion 42a of the hanging surface 42 is lower than the height of the solar cell module 1, so that the solar cell module 1 can be easily removed. Note that, although it is preferable to remove the solar cell modules 1 one by one, it is also possible to remove two by two.
[0055] After removing the predetermined number of solar cell modules 1 near the front, as shown in Fig. 5D, the solar cell modules 1 remaining near the rear surface 33 of the side panel 3 are pulled horizontally or nearly horizontally toward the remaining portion 42a of the hanging surface 42, and then the solar cell modules 1 are removed upward in the same manner as above. The left and right cutouts 36, 37 make it easy to pull them in.
[0056] When the solar cell module 1 is pulled, as shown in FIG. 5E, even if the solar cell module 1 falls in the pulling direction, the solar cell module 1 is received by the upper side of the remaining part 42a of the hanging surface 42 and does not fall completely. Therefore, the solar cell module 1 is not damaged and the worker can easily grab and remove it. In addition, the remaining part 42a of the hanging surface 42 does not fall outward even if the solar cell module 1 falls in the pulling direction due to the first and second horizontal winding bands 6E and 6F. From the viewpoint of preventing the solar cell module 1 from falling forward, the height of the remaining part 42a of the hanging surface 42 is preferably half the height of the solar cell module 1. From the viewpoint of ease of removal of the solar cell module 1, the lower the height of the remaining part 42a of the hanging surface 42, the better, and the remaining part 42a of the hanging surface 42 can prevent the solar cell module 1 from falling forward.
[0057] As described above, in the embodiments of the present disclosure, it is possible to remove multiple solar cell modules 1 one after another from a packaging structure for the solar cell modules 1 safely and quickly with as little effort as possible, thereby improving work efficiency when removing the solar cell modules 1 from above or from the front.
[0058] (Embodiment 2) 6 to 10A-D show a second embodiment of the present disclosure. The configuration of the solar cell module 1 and the hexahedron 17, as well as the point of mounting the solar cell module packaging structure on a pallet 8, are similar to those of the first embodiment, and therefore will not be described here.
[0059] The packaging body 2 includes, for example, a side plate 3, a top plate 4, a bottom plate 5, first to fourth vertically wound outer bands 6A to 6D, and first and second horizontally wound outer bands 6E and 6F. The side plate 3 of the packaging body 2 of the second embodiment includes a left side plate (left surface 31 described below), a right side plate (right surface 32 described below), and a rear plate (rear surface 33 described below), and the top plate 4 includes a front plate (hanging surface 42 described below). The side plate 3, top plate 4, and bottom plate 5 of the packaging body 2 are, for example, cardboard.
[0060] 6 and 8, side plate 3 is formed in a U-shape in plan view to cover and surround three faces of hexahedron 17, namely, the left face, right face, and rear face, and includes a left face 31, a right face 32, and a rear face 33. Left face 31 is the left side plate, right face 32 is the right side plate, and rear face 33 is the rear plate.
[0061] The left surface 31 of the side plate 3 refers to the surface covering each left end surface 13 (corresponding to the left surface of the hexahedron 17) of the solar cell module 1. The right surface 32 of the side plate 3 refers to the surface covering each right end surface 14 (corresponding to the right surface of the hexahedron 17) of the solar cell module 1. The rear surface 33 of the side plate 3 refers to the surface covering the rear surface 12 (corresponding to the rear surface of the hexahedron 17) of the rear solar cell module 1.
[0062] As shown in FIG. 8, a flap 35 is provided on the lower edge of each of the left surface 31, the right surface 32 and the rear surface 33 of the side panel 3.
[0063] 6 and 8, the top panel 4 has a top surface 41 and a hanging surface 42. The top surface 41 is a surface that covers each upper end surface 15 (corresponding to the upper surface of the hexahedron 17) of the group of solar cell modules 1, and the hanging surface 42 is a surface that covers the front surface 11 of the leading solar cell module 1, and is provided so as to hang downward at a right angle to the front edge of the top surface 41. The top surface 41 is a top panel, and the hanging surface 42 is a front panel.
[0064] As shown in FIG. 9, the top board 4 is provided with flaps 43 on the left, right and rear sides of the top surface 41 and on the left and right sides of the hanging surface .
[0065] As shown in FIG. 6, the bottom plate 5 covers each lower end surface 16 (corresponding to the lower surface of the hexahedron 17) of the solar cell modules 1.
[0066] As shown in FIG. 7, the first to fourth vertically wound outer bands 6A to 6D and the first and second horizontally wound outer bands 6E, 6F bind the side plate 3, the top plate 4 and the bottom plate 5 together so that they cannot be separated.
[0067] The first and second vertically wound outer bands 6A, 6B are wound around a central axis along the left-right direction of the hexahedron 17 so as to extend from the hanging surface 42 of the top plate 4 through the top surface 41 of the top plate 4 to the rear surface 33 of the side plate 3, and from the rear surface 33 through the bottom plate 5 to the hanging surface 42 of the top plate 4. The first and second vertically wound outer bands 6A, 6B are spaced apart in the left-right direction of the hexahedron 17.
[0068] The third and fourth vertically wound outer bands 6C, 6D are wound around a central axis along the front-to-rear direction of the hexahedron 17 so as to extend from the left surface 31 of the side plate 3 through the top surface 41 of the top plate 4 to the right surface 32 of the side plate 3, and from the right surface 32 through the bottom plate 5 to the left surface 31 of the side plate 3. The third and fourth vertically wound outer bands 6C, 6D are spaced apart in the front-to-rear direction of the hexahedron 17.
[0069] The first and second horizontally wound outer bands 6E, 6F are wound around a central axis along the vertical direction of the hexahedron 17 so as to extend from the hanging surface 42 of the top plate 4 through the left surface 31 of the side plate 3 to the rear surface 33, and from the rear surface 33 through the right surface 32 to the hanging surface 42 of the top plate 4. The first and second horizontally wound outer bands 6E, 6F are spaced apart in the vertical direction of the hexahedron 17.
[0070] Corner pads 7 are provided at each corner of each of the outer bands 6A to 6F to prevent the tightening load from each of the outer bands 6A to 6F from concentrating on a specific area of the solar cell modules 1. The material of each corner pad 7 may be, for example, cardboard.
[0071] 6 and 8, a notch (referred to as a left notch) 36 is provided in the upper front portion of each left surface 31 of side panel 3. A notch (referred to as a right notch) 37 is provided in the upper front portion of each right surface 32 of side panel 3. Due to left notch 36 and right notch 37, both left surface 31 and right surface 32 are pentagonal in front view.
[0072] As shown in FIG. 10B, the cutout shape is a right-angled triangle when viewed from the front. The left cutout 36 exposes the upper left corner of each of the predetermined number of solar cell modules 1. The right cutout 37 exposes the upper right corner of each of the predetermined number of solar cell modules 1. The left cutout 36 and the right cutout 37 do not cover the front upper portion of the left and right faces of the hexahedron 17, and expose the upper left and upper right corners of a predetermined number of solar cell modules arranged in the front among the multiple solar cell modules 1 forming the solar cell module group. The number of solar cell modules whose upper left and upper right corners are exposed is at least one, but if there are five or more, it becomes easier to remove them.
[0073] 6 and 8, starting position 36a of left cutout 36 is set at the midpoint in the front-to-rear direction of the upper edge of left surface 31 of side panel 3. End position 36b of left cutout 36 is set at the midpoint in the up-to-down direction of the front edge of left surface 31 of side panel 3. By setting starting position 36a and end position 36b at the midpoint in the front-to-rear direction and the up-to-down direction in this manner, the upper left corners and upper right corners of a predetermined number of solar cell modules can be exposed while maintaining the strength of left surface 31 of side panel 3.
[0074] Further, starting position 37a of right cutout 37 is set at the midpoint in the front-to-rear direction of the upper edge of right surface 32 of side panel 3. End position 37b of right cutout 37 is set at the midpoint in the up-to-down direction of the front edge of right surface 32 of side panel 3. By setting starting position 37a and end position 37b at the midpoint in the front-to-rear direction and the up-to-down direction in this manner, the upper left corners and upper right corners of a predetermined number of solar cell modules are exposed while the strength of right surface 32 of side panel 3 can be maintained.
[0075] Next, a method for unpacking the above-mentioned packaging structure for the solar cell module will be described with reference to FIGS. 10A to 10D.
[0076] In the packaging structure for solar cell module 1 shown in FIG. 7, the first to fourth vertically wound outer bands 6A to 6D, the first and second horizontally wound outer bands 6E, 6F and all of the corner pads 7 are removed as shown in FIG. 10A.
[0077] In addition, each of the flaps 35 of the side panel 3 is overlapped on the underside of the bottom panel 5, and the hexahedron 17 is placed on top of them, so that the side panel 3 does not fall over.
[0078] Thereafter, the top plate 4 is removed. As a result, as shown in Fig. 10B, the hanging surface 42 is removed, and almost the entire front surface 11 of the leading solar cell module 1 is exposed. Also, the upper left corners and upper right corners of a predetermined number of solar cell modules 1 closest to the leading edge are exposed from the left and right cutouts 36, 37.
[0079] After this, the inner band 18 of the hexahedron 17 is cut. This allows the worker to grasp the upper left and upper right corners of the solar cell module 1 placed first with his or her hands, as shown in Fig. 10C, and remove it sideways into the open portion where the hanging surface 42 of the top plate 4 has disappeared. The left and right cutouts 36, 37 allow it to be easily pulled in.
[0080] Moreover, when removing the solar cell modules 1, there is no need to lift the solar cell modules 1 as in the first embodiment, so the labor required by the worker can be significantly reduced compared to the first embodiment. Although it is preferable to remove the solar cell modules 1 one at a time, it is also possible to remove two at a time.
[0081] Then, after removing the specified number of solar cell modules 1 toward the front, the solar cell modules 1 remaining toward the rear surface 33 of the side panel 3 can be successively pulled horizontally or nearly horizontally toward the open portion and then removed, as shown in FIG. 10D.
[0082] As described above, in the embodiment of the present disclosure, it is possible to sequentially remove multiple solar cell modules 1 from a packaging structure safely and quickly with as little effort as possible, thereby improving work efficiency when removing solar cell modules 1 from the front.
[0083] (Embodiment 3) 11 to 15A-E show embodiment 3 of the present disclosure. The configuration of solar cell module 1 and hexahedron 17, as well as the point of mounting the solar cell module packaging structure on a pallet 8, are similar to embodiment 1, and therefore will not be described here.
[0084] The packaging body 2 includes, for example, a side plate 3, a top plate 4, a bottom plate 5, first to fourth vertically wound outer bands 6A to 6D, and first and second horizontally wound outer bands 6E and 6F. The side plate 3 of the packaging body 2 of the third embodiment includes a left side plate (a left surface 31 described below), a right side plate (a right surface 32 described below), a rear plate (a rear surface 33 described below), and a front plate (a front surface 34 described below). The side plate 3, the top plate 4, and the bottom plate 5 of the packaging body 2 are made of, for example, cardboard.
[0085] The side plate 3 is formed in a rectangular cylindrical shape that surrounds the four sides of the hexahedron 17, the front, rear, left and right, and has a left side 31, a right side 32, a front side 34, and a rear side 33. The left side 31 is the left side plate, the right side 32 is the right side plate, the rear side 33 is the rear plate, and the front side 34 is the front plate.
[0086] The left surface 31 of the side panel 3 refers to the surface covering each left end surface 13 (corresponding to the left surface of the hexahedron 17) of the solar cell module 1. The right surface 32 of the side panel 3 refers to the surface covering each right end surface 14 (corresponding to the right surface of the hexahedron 17) of the solar cell module 1. The front surface 34 of the side panel 3 refers to the surface covering the front surface 11 of the leading solar cell module 1. The rear surface 33 of the side panel 3 refers to the surface covering the rear surface 12 (corresponding to the rear surface of the hexahedron 17) of the trailing solar cell module 1.
[0087] As shown in Figure 13, this side panel 3 is manufactured by sequentially connecting the left side 31, front side 34, and right side 32 to the left side of the rear side 33, and forming a shape in which the glue flap 35n is connected to the left side of the right side 32. The front side 34, left side 31, rear side 33, and right side 32 are then bent into a square cylindrical shape in a plan view, and the glue flap 35n is bent and attached to the right side of the inner surface of the rear side 33 to obtain a square cylindrical side panel 3.
[0088] 11, the top plate 4 covers only the upper end faces 15 (corresponding to the upper faces of the hexahedrons 17) of the solar cell modules 1. Flaps 43 are provided on the left, right, front and rear edges of the top plate 4, as shown in FIG.
[0089] As shown in FIG. 11, the bottom plate 5 covers the lower end faces 16 (corresponding to the lower faces of the hexahedrons 17) of the solar cell modules 1.
[0090] As shown in FIG. 12, the first to fourth vertically wound outer bands 6A to 6D and the first and second horizontally wound outer bands 6E, 6F bind the side plate 3, the top plate 4 and the bottom plate 5 together so that they cannot be separated.
[0091] The first and second vertically wound outer bands 6A, 6B are wound around a central axis along the left-right direction of the hexahedron 17 so as to extend from the front surface 34 of the side panel 3 through the top surface 41 of the top panel 4 to the rear surface 33 of the side panel 3, and from the rear surface 33 through the bottom panel 5 to the front surface 34 of the side panel 3. The first and second vertically wound outer bands 6A, 6B are spaced apart in the left-right direction of the hexahedron 17.
[0092] The third and fourth vertically wound outer bands 6C, 6D are wound around a central axis along the front-to-rear direction of the hexahedron 17 so as to extend from the left surface 31 of the side plate 3 through the top surface 41 of the top plate 4 to the right surface 32 of the side plate 3, and from the right surface 32 through the bottom plate 5 to the left surface 31 of the side plate 3. The third and fourth vertically wound outer bands 6C, 6D are spaced apart in the front-to-rear direction of the hexahedron 17.
[0093] The first and second horizontally wound outer bands 6E, 6F are wound around a central axis along the vertical direction of the hexahedron 17 so as to extend from the front surface 34 of the side plate 3 through the left surface 31 to the rear surface 33 of the side plate 3, and from the rear surface 33 through the right surface 32 to the front surface 34 of the side plate 3. The first and second horizontally wound outer bands 6E, 6F are spaced apart in the vertical direction of the hexahedron 17.
[0094] Corner pads 7 are provided at each corner of each of the outer bands 6A to 6F to prevent the tightening load from each of the outer bands 6A to 6F from concentrating on a specific area of the solar cell modules 1. The material of each corner pad 7 may be, for example, cardboard.
[0095] As shown in Figures 11 and 13, a perforation (referred to as a left perforation) 38 is provided at each upper front portion of the left surface 31 of the side panel 3. A perforation (referred to as a right perforation) 39 is provided at each upper front portion of the right surface 32 of the side panel 3. A perforation (referred to as a front perforation) 34a is provided on the front surface 34 of the side panel 3. The left perforation 38 allows the front upper portion of the left panel to be separated. The right perforation 39 allows the front upper portion of the right panel to be separated. The front perforation 34a allows the upper and lower portions of the front panel to be separated.
[0096] The left perforation 38 has an inclined straight line shape connecting a starting position 38a, which is set in the middle of the front-to-back direction of the upper edge of the left surface 31 of the side panel 3, and an ending position 38b, which is set in the middle of the top-to-bottom direction of the front edge of the left surface 31.
[0097] The right perforation 39 has an inclined straight line shape connecting a starting position 39a set at the midpoint in the front-to-back direction of the upper edge of the right surface 32 of the side panel 3 and an ending position 39b set at the midpoint in the up-down direction of the front edge of the right surface 32.
[0098] The front perforation 34a is shaped as a horizontal straight line connecting the end position 38b of the left perforation 38 and the end position 39b of the right perforation 39.
[0099] Next, a method for unpacking the above-mentioned packaging structure for the solar cell module will be described with reference to Figs. 15A to 15E.
[0100] In the packaging structure for solar cell module 1 shown in FIG. 12, the first to fourth vertically wound outer bands 6A to 6D, the first and second horizontally wound outer bands 6E, 6F and all of the corner pads 7 are removed as shown in FIG. 15A.
[0101] Thereafter, as shown in FIG. 15B, the top plate 4 is removed, the side plate 3 is raised a predetermined amount, and the inner band 18 of the hexahedron 17 is cut.
[0102] Then, the side panel 3 is lowered by cutting off the left perforation 38, the right perforation 39 and the upper part of the front perforation 34a of the side panel 3. As a result, the upper front corner area of the left face 31, the upper front corner area of the right face 32 and the upper part of the front face 34 are cut out, so that the upper left corners and upper right corners of a predetermined number of solar cell modules near the front of the solar cell module group 1 are exposed from the cut-out areas, and the upper part of the front face 11 of the front solar cell module 1 is exposed. Note that the side panel 3 may be lifted a predetermined amount after cutting off the left perforation 38, the right perforation 39 and the upper part of the front perforation 34a of the side panel 3, and then the inner band 18 of the hexahedron 17 may be cut.
[0103] In this way, as shown in FIG. 15C, a worker can grasp the upper left and upper right corners of the leading solar cell module 1 with his or her hands and remove it upward.
[0104] Moreover, when removing the solar cell module 1, it is only necessary to lift the solar cell module 1 above the remaining lower region 34b on the front surface 34 of the side panel 3, so the labor required by the worker can be reduced compared to the case where a large solar cell module 1 is lifted higher than the upper end surface 15 of another large solar cell module 1. In other words, the height of the remaining lower region 34b on the front surface 34 is lower than the height of the solar cell module 1, so that the solar cell module 1 can be easily removed. Note that, although it is preferable to remove the solar cell modules 1 one by one, it is also possible to remove two by two.
[0105] Then, after removing the specified number of solar cell modules 1 near the front, as shown in FIG. 15D, the solar cell modules 1 remaining near the rear surface 33 of the side panel 3 are pulled horizontally or nearly horizontally toward the lower region 34a of the front surface 34, and then removed upward in the same manner as described above.
[0106] When the solar cell module 1 is pulled in, even if the solar cell module 1 remaining near the rear surface 33 of the side plate 3 falls in the direction of pulling, as shown in FIG. 15E, the solar cell module 1 is received by the upper edge of the remaining lower area 34a of the front surface 34 of the side plate 3 and does not fall completely. Therefore, the solar cell module 1 is not damaged and is easy for an operator to grasp and remove. From the viewpoint of preventing the solar cell module 1 from falling forward, the height of the remaining lower area 34b of the front surface 34 is preferably half the height of the solar cell module 1. From the viewpoint of ease of removal of the solar cell module 1, the lower the height of the remaining lower area 34b of the front surface 34, the better, and the remaining lower area 34b of the front surface 34 can prevent the solar cell module 1 from falling forward.
[0107] As described above, in the embodiments of the present disclosure, it is possible to remove multiple solar cell modules 1 one after another from a packaging structure for the solar cell modules 1 safely and quickly with as little effort as possible, thereby improving work efficiency when removing the solar cell modules 1 from above or from the front.
[0108] The present disclosure is not limited to the above-described first to third embodiments, and may be modified as appropriate within the scope of the claims and equivalents thereto.
[0109] (1) Figure 16 shows a fourth embodiment. In the fourth embodiment, the inclined straight lines of the left and right cutouts 36, 37 of the first embodiment are L-shaped with rounded inner corners. Note that only the right cutout 37 is shown in Figure 16, but the left cutout 36 is similar. The fourth embodiment also provides the same functions and effects as the first embodiment.
[0110] (2) Fig. 17 shows embodiment 5. In embodiment 5, the inclined straight lines of the left and right cutouts 36, 37 of embodiment 1 are L-shaped, and the inner corners are made inclined straight lines to round the connecting corners. Note that Fig. 17 only shows the right cutout 37, but the left cutout 36 is similar. With embodiment 5, the same actions and effects as embodiment 1 can be obtained.
[0111] (3) Fig. 18 shows a sixth embodiment. In the sixth embodiment, the inclined straight lines of the left and right cutouts 36, 37 of the first embodiment are L-shaped. Although Fig. 18 shows only the right cutout 37, the left cutout 36 is similar. In the sixth embodiment, the same action and effect as in the first embodiment can be obtained.
[0112] (4) Figure 19 shows a seventh embodiment. In the seventh embodiment, the left and right cutouts 36, 37 of the first and second embodiments are perforations (only the right perforation 37X is shown in Figure 19, but the left cutout 36 is similar). In the seventh embodiment, the same actions and effects as those of the first and second embodiments can be obtained.
[0113] (5) Figure 20 shows embodiment 8. In embodiment 8, the left and right flaps 43 on the hanging surface 42 of the tabletop 4 of embodiment 1 are provided only in the range from the middle in the vertical direction (also called the hanging direction) to the lower end (also called the tip in the hanging direction). In embodiment 8, the same action and effect as embodiment 1 can be obtained.
[0114] (6) Although not shown, in the first and second embodiments, it is possible to pack the solar cell modules 1 in such a way that the rear surface 33 of the side panel 3 covers the front surface 11 of the leading solar cell module 1, and the hanging surface 42 of the top panel 4 covers the rear surface 12 of the trailing solar cell module 1. Such a configuration is referred to as a ninth embodiment. The same actions and effects as those of the first and second embodiments can be obtained in this ninth embodiment.
[0115] (7) Although not shown, in the first and second embodiments, it is possible to set the terminal position 36b of the left cutout 36 at a position corresponding to the lower edge of the left end face 13 of the leading solar cell module 1, and set the terminal position 37b of the right cutout 37 at a position corresponding to the lower edge of the right end face 14 of the leading solar cell module 1. Such a configuration is referred to as the tenth embodiment.
[0116] In the tenth embodiment, the areas of the left cutout 36 and the right cutout 37 are relatively large, so that the effort required to remove the solar cell module 1 can be reduced compared to the first and second embodiments.
[0117] (8) Although not shown, in the first and second embodiments, instead of the left and right notches 36 and 37 in the side panel 3, perforations can be provided, and the portion above the perforations can be cut off to form the cut-off area. Such a configuration is referred to as the eleventh embodiment.
[0118] In this embodiment 11, a method of opening the package structure of the solar cell modules 1 will be described. The difference between this embodiment 11 and the embodiment 1 is that before or after cutting off the part above the front perforation 44 on the hanging surface 42 of the top plate 4, the part above the perforations that replace the left notch 36 and the right notch 37 is cut off. As a result, the upper corners of the left front side of the left surface 31 and the upper corners of the right front side of the right surface 32 of the side plate 3 are cut off, so that the upper left corners and the upper right corners of the predetermined number of solar cell modules 1 near the front are exposed. The other operations are basically the same as those in the embodiment 1, so the explanation here is omitted. The same actions and effects as those of the embodiments 1 and 2 can be obtained in this embodiment 11 as well.
[0119] (9) Although not shown, in the third embodiment, instead of the left perforation 38, the right perforation 39, and the front perforation 34a of the side panel 3, it is possible to cut off the areas above the perforations 38, 39, and 34a. Such a configuration is referred to as the twelfth embodiment. The cut-off areas are referred to as cutouts, and the sides corresponding to the left perforation 38, the right perforation 39, and the front perforation 34a are referred to as the first line, the second line, and the third line, respectively, although not shown.
[0120] In this embodiment 12, the effort required to cut above the left perforation 38, right perforation 39 and front perforation 34a as in the third embodiment is eliminated, thereby improving work efficiency when removing the solar cell module 1 compared to the third embodiment.
[0121] (10) Although not shown, in the first to twelfth embodiments, it is possible to pack the solar cell modules 1 so that the rear surface 33 of the side panel 3 covers the front surface 11 of the leading solar cell module 1, and the front surface 34 of the top panel 4 covers the rear surface 12 of the trailing solar cell module 1. This form is referred to as a thirteenth embodiment. The thirteenth embodiment also provides the same functions and effects as the first embodiment. [Industrial Applicability]
