Embodiment 1 FIG.
FIG. 1 is an external view of a first embodiment of a solar cell module package according to the present invention. FIG. 2 is a cross-sectional view of the solar cell module package according to the first embodiment, showing a cross section taken along line II-II in FIG. FIG. 3, FIG. 4 and FIG. 5 are views showing a package constituting the solar cell module package.

The solar cell module package according to the first embodiment includes a package 1 in which a solar cell module 5 is wrapped with wrapping paper 6, a pallet 3 on which a plurality of packages 1 are stacked, and a plurality of stacked packages 1. A packaging body protection member 2 that protects corners, and a wrapping material 4 that wraps and fixes the plurality of packaging bodies 1, the pallet 3, and the packaging body protection member 2 together are provided. In FIG. 2, the wrapping material 4 is indicated by a one-dot chain line.

  As shown in FIGS. 3, 4, and 5, the package 1 is formed by wrapping the solar cell module 5 with wrapping paper 6. The length of the wrapping paper 6 in the longitudinal direction is about 1.5 times the length of the solar cell module 5, and the length in the short direction is substantially the same as the width of the solar cell module 5. Length. The wrapping paper 6 is disposed so as to cover the back sheet side (rear surface side) of the solar cell module 5, and about ¼ of the length of the solar cell module 5 in each of the short sides of the solar cell module 5. Folded back to the glass side (front side). The wrapping paper 6 is pulled toward the center of the solar cell module 5 at the ends of the wrapping paper 6 at both ends folded back to the glass surface side so as to be in close contact with the glass surface and the frame surface. The end portions of the folded wrapping paper 6 and the wrapping paper 6 on the back sheet side are fixed at four points with the tape 7 so that the wrapping paper 6 does not sag. By covering the back sheet side of the solar cell module 5 entirely with the wrapping paper 6, it is possible to protect the terminal box and the connector installed on the back sheet side in addition to the back sheet which is more easily damaged than glass. it can. Moreover, the usage-amount of material can be reduced by covering only a part by the side of a glass surface with the wrapping paper 6. FIG.

  When the packaging body 1 is loaded on the pallet 3 by the automatic robot, the position where the pawl 10 of the automatic robot chucks the packaging body 1 and the fixing position of the tape 7 are matched. As a result, the nail 10 of the automatic robot is prevented from entering the gap between the frame and the wrapping paper 6, and the frame damage by the nail 10 of the automatic robot is prevented. By taking this form, it is possible to stack pallets with an automatic robot, as in the case of corrugated cardboard packaging, and to suppress an increase in the number of workers.

  By providing the tape 7 for fixing the wrapping paper 6 at four locations, the packaging body 1 can be held by the four claws of the automatic robot, and therefore can be stably held when the automatic robot is loaded.

  A plurality of the packages 1 formed in this way are stacked on the pallet 3 larger than the outer shape of the solar cell module 5. FIG. 6 is a diagram illustrating a state in which packaging bodies are stacked by an automatic robot. FIG. 7 is a cross-sectional view showing a state where the automatic robot chucks the package.

  The pallet 3 is made of wood in the same manner as that used for normal transportation, and a hole for inserting a claw of a transfer forklift is provided on a side surface. The size of the pallet 3 is larger than the outer shape of the solar cell module 5 so that the packaging body 1 does not protrude from the pallet 3 even if it is slightly deviated in consideration of the accuracy when stacking with an automatic robot. ing.

After stacking a predetermined number, for example, 10 packaging bodies 1, the packaging body protection members 2 are arranged outside the four corners of the stacked packaging bodies 1. The packaging body protection member 2 is formed by stacking cardboards, is bent along the corners of the packaging body 1, and is disposed so as to cover the corners of the packaging body 1. The height of the packaging body protection member 2 is substantially equal to the height of the plurality of packaging bodies 1 stacked. The package protection member 2 is temporarily fixed to the package 1 using tapes 12 on the outer sides of the four corners of the stacked package 1.

A plurality of packaging bodies 1 are stacked on a pallet 3, a packaging body protection member 2 is disposed at a corner, and the uppermost packaging body 1 has an area substantially equal to the packaging body 1 on the uppermost packaging body 1. The protective paper 11 which protects the glass surface of 1 solar cell module 5 is placed. Thereafter, the periphery is wound with a wrapping material 4 to fix the pallet 3, the plurality of packaging bodies 1, and the packaging body protection member 2.

The wrapping material 4 is a transparent polyethylene film, for example, and has stretchability and adhesiveness. By wrapping the wrapping material 4 so as to cover the upper corners of the pallet 3, the side surfaces of the plurality of packaging bodies 1, the packaging body protection member 2, and the upper corners of the uppermost packaging body 1, the pallet 3 And the some package 1 and the package protection member 2 can be fixed. Since the wrapping material 4 has stretchability and adhesiveness, the wrapping material 4 can be wound without any gaps by being wound without any slack, and can be easily fixed as a whole. .

Further, since the wrapping material 4 is made of a transparent material, the wrapping operation can be easily performed, and the packaging body 1 and the packaging body protection member 2 in the wrapping material 4 can be easily visually recognized even after being fixed. .

Thus, the solar cell module package is formed by winding the pallet 3, the plurality of packages 1, and the package protection member 2 with the wrapping material 4. The solar cell module 5 has a strong frame on the outer periphery, and originally has a strength that does not cause a problem even when stacked.

By wrapping the solar cell module 5 with the wrapping paper 6 to form a package, and then stacking the frames, the frames can be prevented from being rubbed and scratched. Further, by protecting the four corners of the package 1 stacked in the packaging member protecting member 2 can prevent the package 1 is shifted. Furthermore, by winding the wrapping material 4 around the packaging body 1 and the packaging body protection member 2, the packaging body protection member 2 can be firmly pressed against the packaging body 1 and the displacement of the packaging body 1 can be suppressed.

  Further, by winding the wrapping material 4 also on the upper corner of the pallet 3, the plurality of packaging bodies 1 and the pallet 3 can be fixed. Further, by winding the wrapping material 4 also on the upper corner portion of the uppermost package 1, the package 1 can be prevented from moving up and down and fixed. Thereby, even if there is vibration during transportation, the solar cell module 5 can be firmly fixed to the pallet 3, so that the solar cell module 5 can be prevented from being damaged or damaged.

  Since the wrapping paper 6 that covers the solar cell module 5 is lighter than the corrugated cardboard, the solar cell module package can be reduced in weight. Moreover, since the packaging paper 6 can be broken and the solar cell module 5 can be taken out in the unpacking operation, the workability is remarkably improved as compared with the case where the solar cell module 5 is individually packed with cardboard. Furthermore, since the weight and bulk of unnecessary packing materials after unpacking can be reduced, recovery at the time of disposal is easy. Furthermore, by using the wrapping paper 6 that is cheaper than cardboard, the material cost of the packaging material can be reduced.
