Description

  TECHNICAL FIELD The present invention relates to a solar cell panel holding casing, a cardboard box assembling method, and a cardboard box disassembling method, and in particular, a solar cell panel holding casing that holds a large and heavy solar cell panel and uses a recyclable material. The present invention relates to a cardboard box assembly method and a cardboard box disassembly method.

  Solar power generation is being promoted as part of the use of natural energy. 2. Description of the Related Art Mass production technology for unit power generation panels (power generation modules), which are a set of power generation film forming elements that convert light energy into electrical energy, has been advanced. A large number of unit power generation panels are distributed globally and transported by trucks and container ships. The power generation element of the unit power generation panel and its electric output line are not subject to vibration. Careful packaging of each panel in a vibration-proof manner causes an increase in packaging materials. It is required to pack a large number of panels in one unit packing box. A technique for packing a large number of panels in a unit packing box is known from Patent Document 1 described later.

With the advancement of technology in recent years, large-sized panels with dimensions of 1.1 m (width) x 1.4 m (length) and a mass of 20 or more kg per sheet have been manufactured in the amorphous solar cell panel. From the viewpoint of resource and energy saving, “Structure that cannot disassemble and fold the main body of the packaging box”, “Structure that stores the product vertically and puts it in and out vertically” described in Patent Document 1 for the following reasons , "Use of non-recyclable materials such as foamed resin molded products and plastic cardboard for packaging boxes" cannot be employed.
(1) Since large and large-mass solar panel packaging boxes are large in size, if they are not disassembled and foldable, it will take a lot of money to transport empty packaging boxes, and it will be very large in factories and installation sites. Storage space for an empty packaging box is required.
(2) Since the packaging box for large and large-mass solar panels is about 1.5m in height, the top and bottom of the large and large-mass solar panel must be lifted up to about 3m in a structure that is taken in and out in the vertical direction. It cannot be taken in and out, and it cannot be taken in and out safely at the factory and the installation site.
(3) From the viewpoint of saving resources and energy, it is desirable to use recyclable or reusable materials for packaging, and corrugated cardboard as packaging materials that can be recycled not only in Japan but also from overseas customers. Often specified for use. Instead of Patent Document 1, it is possible to pack each panel and transport it by stacking and securing it horizontally on a pallet. In this case, the following problems are derived and adopted. Can not do it.

(4) When the output of each solar panel varies within the allowable tolerance, and it becomes necessary to adjust the total output for each packing unit when packing at the factory, or to adjust the output for each installation location at the installation site Then, an operation of confirming the output with the serial number attached to the back surface of each packed solar cell panel and taking out a predetermined panel occurs. In this case, in order to take out the panel of the serial number having a predetermined output from the packaging for each panel stacked on the pallet, the packaging for each stacked panel is moved to a wide place and unpacked. In addition, it is necessary to confirm the serial number on the back of the panel, which requires a lot of construction cost and work space.
(5) To pack each panel, a lot of packing material costs and artificial costs are required.
(6) Packaging for each panel is stacked horizontally on a pallet, secured with a band, etc., and transported by truck or ship. This method is unstable due to severe vibration or shaking during transportation. It is necessary to limit the number of stacks to be relatively small in order to prevent load slipping and collapse, leading to reduced loading efficiency on trucks or container ships, increased transportation costs, and extensive storage at factories or installation sites. Space is needed.

  In order to popularize solar power generation panels, cost reduction is desired. In addition to reducing the manufacturing cost of the element itself, it is necessary to reduce the packaging cost for mass transportation. It is next important that the post-use treatment of a large number of packaging boxes is appropriate. It is desirable that the material of the packaging container be a material that can be recycled. In particular, as such a material, corrugated cardboard that is manufactured recyclely and reused after use is particularly preferable. Corrugated cardboard is a material whose use is preferred worldwide. In order to reduce the cost, it is further desirable that the packaging unit can be assembled and disassembled. The reduction in the assembly and dismantling efforts further reduces the overall cost of the distribution process.
