To do.

  The above solar cell panel packing material is composed of only two parts, a box-shaped container and a lid member, both of which are integrally molded products of foamed resin, and the management of the parts is extremely easy. Also, when packing solar cell panels, the required number of solar cell panels are dropped from above into a box-shaped container that has already been integrally molded, using the support grooves formed therein as a guide, and then the box-shaped container is packed. It is only necessary to close the opening of the vessel with a lid member, and the operation is very easy and high working efficiency can be obtained.

  Furthermore, in the packing material for solar cell panels according to the present invention, a space is formed in a region along each side wall provided with the ridges at the bottom of the container, and the box on the top surface of the lid member is capped. An air gap is also formed in a region along each side wall provided with the ridges of the shape container. The presence of this gap can alleviate the impact of the impact when the packing material is dropped directly on the corner portion of the packaging material for solar cell panel that is accommodated, so that the corner portion of the packed solar cell panel is damaged. Can be effectively avoided. Thereby, the package of the solar cell panel provided with high safety is obtained.

  In still another aspect of the packaging material for a solar cell panel according to the present invention, the solar cell panel packing material further includes a pallet that supports the box-shaped container. In this aspect, a box-shaped container that houses a solar cell panel and is covered on a pallet is placed and tightened together with a band or the like, thereby facilitating and stabilizing the handling of the package during transportation and storage. be able to.

  The solar cell panel is thicker than a glass substrate or the like, is not easily damaged, and does not require measures against generation of shaving powder. For this reason, even a packing material consisting only of a box-shaped container and a lid, both of which are integrally molded products of foamed resin, such as a packing material for a solar cell panel according to the present invention, is a hindrance as a packing material for a solar cell panel. Can be used. Further, it is not necessary to separately dispose cushioning materials such as EPE on the upper and lower edge portions of the accommodated solar cell panel, and the bottom portion of the box-shaped container and the top surface portion of the lid member have special support grooves. It does not matter if it remains flat. Of course, you may make it form the support groove which consists of a several protruding item | line in the bottom part of a box-shaped container and the top | upper surface part of a cover member so as to correspond to the support groove formed in the side wall of a box-shaped container.

  The box-shaped container and the lid member according to the present invention are preferably integrally formed by in-mold foam molding. Resin materials include polystyrene resins, polyolefin resins (eg, polypropylene resins, polyethylene resins, etc.), polyester resins (eg, polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, etc.), polycarbonate resins, polylactic acid Based resins and the like. Among these, it is preferable to use a composite resin containing polystyrene and polyethylene. The magnification of the foam may be appropriately set in consideration of the weight of the solar cell panel to be packed, etc., but is preferably about 20 to 40 times from the viewpoint of good buffering properties, light weight and economy. .

  ADVANTAGE OF THE INVENTION According to this invention, the packing material for solar cell panels which can ensure high safety | security with respect to an external impact can be obtained, while packing work can be performed with high working efficiency.

The packaging material 1 for solar cell panels is comprised with the box-shaped container 10 and the cover member 20 which are both made of foaming resin. Although not limited, in this example, both the box-shaped container 10 and the lid member 20 are formed by in-mold foam molding of foamable resin particles made of a composite resin containing polystyrene and polyethylene, and the density is 0.05 to 0. About 0.025 g / cm ³ .

  The box-shaped container 10 includes a bottom plate 11 and four side walls 12 and has a cubic shape as a whole. The upper edge side of the side wall is a stepped portion 13 whose inner side is convex. A plurality of parallel protrusions 14 are formed in the vertical direction on the inner surfaces of the pair of opposing sidewalls 12a and 12b in the four sidewalls 12, and the two adjacent protrusions 14 and 14 are adjacent to each other. A plurality of support grooves 15 that support the side end surfaces of the solar cell panel P are formed therebetween. The interval between the protrusions 14, that is, the width of the support groove 15 is the thickness of the solar cell panel P to be accommodated, how many solar cell panels P are inserted into one support groove 15, and the like. Set appropriately in consideration.

  As shown in FIG. 2, the inner side surface 11 a of the bottom plate 11 of the box-shaped container 10 is a flat surface, and in the region along the side walls 12 a and 12 b where the ridges 14 are formed, there are gaps along the side walls. 16 and 16 are formed. The outer edge 16a of each air gap 16 is a vertical surface flush with the inner surface of each side wall 12, and the inner edge 16b of each air gap 16 is positioned approximately 1 cm inward from the outer edge 16a. Yes. Moreover, the depth of each space | gap 16 should just be about 1 cm.

By an appropriate means, one or a plurality of solar cell panels P are lifted in a standing posture, and the side end surfaces thereof enter into the support grooves 15 formed between the ridges 14 formed in the box-shaped container 10. Then drop from the top. Thereby, each solar cell panel P has a stable posture in the box-shaped container 10 in a posture in which the lower end edge rides on the inner surface 11a of the bottom plate 11 of the box-shaped container 10 and both end surfaces are supported by the support grooves 15. Be contained. In that posture, gaps 16 and 16 are formed at the lower corners of the solar cell panels P and in the vicinity thereof at positions along the inner surfaces of the side walls 12a and 12b on the inner side surface 11a of the bottom plate 11 of the box-shaped container 10. Therefore, the container bottom plate 11 is not touched.

  Next, the lid member 20 is placed over the opening of the box-shaped container 10. The state is shown in FIG. As shown in FIG. 2, the stepped portion 13 formed on the upper edge side of the side wall 12 of the box-shaped container 10 and the stepped portion 23 formed on the lower edge side of the side wall 22 of the lid member 20 are fitted with the lid covered. The lid member 20 is attached to the box-shaped container 10 in a stable state. As shown in FIG. 2, when the lid member 20 is attached to the box-shaped container 10, the top surface 21 a of the lid member 20 is in contact with or slightly away from the upper edge of the accommodated solar cell panel P. Various dimensions of the lid member 20 are set so that

  After that, if necessary, the packing work is completed by passing and tightening a band (not shown) through the opening 31 of the pallet 30 to the package with the lid, and the packing work is completed. Provided.
