Description

  The present invention relates to a solar cell module mounting unit that stacks solar cell modules horizontally and stacks them in multiple stages during transportation or the like.

  DESCRIPTION OF RELATED ART Conventionally, the glass plate package for packing and transporting glass substrates for flat panel displays (FPD), such as a liquid crystal display, a plasma display, a field emission display, and an electroluminescence display, is known (for example, patent document 1). reference).

  FIG. 8 is a perspective view showing the entire configuration of the glass plate package according to Patent Document 1. As shown in FIG.

  The glass plate package 101 is configured to accommodate a glass plate laminate 106 formed by laminating a plurality of glass plates in a flat position above the base portion 103 of the pallet 102, and A glass plate receiving portion 104 having a size corresponding to the size of the glass plate is disposed on the upper portion of the portion 103, and a buffer 105 is laid on the upper portion of the glass plate receiving portion 104 over substantially the entire area thereof. The glass plate laminated body 106 is placed on the upper portion of the buffer body 105, and the glass plate laminated body 106 is positioned in the glass plate receiving portion 104 on the outer side of the buffer body 105 and the glass plate laminated body 106. A plurality of presser plates 107 for restricting the movement are attached to be separated from each other.

  Further, at the four corners of the base portion 103, columns 108 are erected to support the upper glass plate package when the glass plate packages 101 are stacked in a plurality of stages, and are formed at the upper ends of the four columns 108. In a state in which the glass plate packing body 101 is integrated in a plurality of stages by fitting the protruding portion 108a into a recess (not shown) formed on the lower surface of the base portion 103 in the upper glass plate packing body 101. Various types of transportation are possible.

  By the way, when the glass plate package 101 described above is used for packing a solar cell module, the solar cell module is provided with a terminal box on the back surface side, and therefore cannot be simply stacked flat. . Therefore, a spacer member or the like for opening a certain gap between the upper and lower adjacent solar cell modules is further required, and the above glass plate package 101 cannot be simply used.

  In addition, the glass plate packaging body 101 is provided with upright quadrangular columnar columns 108 for stacking vertically on the outside of each corner of the glass plate laminate 106. Therefore, since the outer shape of the base part 103 is considerably larger than the outer shape of the glass plate laminate 106, for example, there is a problem that the loading efficiency of the glass plate laminate 106 when loaded in a transport container or the like is poor. . That is, when viewed with the glass plate laminate 106, a considerable gap is generated between the crow plate laminates 106 adjacent in the lateral direction.

  Therefore, when considering the loading efficiency to a transport container etc., the structure like the said glass plate package 101 is not preferable.

  FIG. 9 shows an example of a solar cell module stacker that stacks and packs solar cell modules in multiple stages during transportation or the like.

  This solar cell module stacker 2 is arranged to support a rectangular substrate 21 and each corner (corner portion) 10a of the solar cell module 10 that is disposed at four corners of the substrate 21 and stacked horizontally. The structure is provided with the member 22 and is particularly suitably used for stacking a solar cell module having a frameless structure (laminated glass structure).

  10 and 11 show the configuration of the support member 22. FIG. 10 is a perspective view seen from an obliquely upper side, and FIG. 11 is a perspective view seen from an obliquely lower side.

  The support member 22 has a structure for receiving the corner portion 10a of the solar cell module 10 from below. The base portion 23 is bent in an L shape in plan view, and the inner wall surface of the base portion 23 is orthogonal to the wall surface. And a receiving portion (supporting portion) 28 extending in the direction.

  The receiving portion 28 is formed so as to receive the corner portion 10a of the solar cell module 10 from below, and the overall shape of the support member 22 is formed in a substantially L-shaped longitudinal section.

  The upper end surface 23a and the lower end surface 23b of the base portion 23 are respectively provided with a fitting convex portion 25 and a fitting concave portion 26 for sequentially fitting with another support member 22 disposed adjacent to the upper and lower sides. . Two fitting protrusions 25 are provided, one on each upper end surface 23 a of the base part 23, and one fitting recess 26 is provided on each lower end face 23 b of each piece of the base part 23. A total of two are provided. However, the number of the fitting convex portions 25 and the fitting concave portions 26 is not limited to this. For example, one is L-shaped on each of the upper end surface 23a and the lower end surface 23b of the substrate portion 23, for example, two in total. It may be provided. The support member 22 having such a shape is formed by injection molding using a resin such as PP (polypropylene) or ABS (acrylonitrile / butadiene / styrene copolymer).

  On the other hand, on the substrate 21, fitting convex portions 29 are formed at four corners so as to face the fitting concave portions 26 of the support member 22. The substrate 21 has a two-layer structure in which an upper substrate 21a and a lower substrate 21b are supported by a plurality of horizontal rails 21c, and a gap between the upper substrate 21a and the lower substrate 21b is A hole for passing a binding band 7 described later, and a hole into which a fork of a forklift is inserted when loading into a transport container or the like.

  Using the support member 22 having such a shape, the solar cell modules 10 having a frameless structure are horizontally stacked by the procedure shown in FIGS.

  That is, first, the fitting recesses 26 of the first-stage support member 22 are fitted to the four fitting projections 29 of the substrate portion 21 (FIG. 12), and in this state, one step is placed on each support member 22. It mounts so that the corner part 10a of the four corners of the solar cell module 10 of eyes may be mounted (FIG. 13). Next, the fitting concave portions 26 of the second-stage support member 22 are fitted into the fitting convex portions 25 of the respective support members 22 (FIG. 14). It mounts so that the corner part 10a of the four corners of the solar cell module 10 of a step may be mounted (FIG. 15). By repeating this procedure a predetermined number of times, as shown in FIG. 16, a predetermined number of solar cell modules 10 (10 to 30 in the figure but actually 20 to 30) are stacked in multiple stages on the substrate unit 21. To do.

  After that, as shown in FIG. 17, a top plate 6 made of, for example, cardboard is formed on the upper surface of the uppermost solar cell module 10 as a buffer so as to be wider than the width of the solar cell module 10.

  And as shown in FIG. 18, the both sides of the longitudinal direction of the top plate 6 are arranged along the edge part 10b of the longitudinal direction of the solar cell module 10, and the outer surfaces of the supporting member 22 arrange | positioned at the both corner parts 10a ( That is, it is bent along a straight line L (see also FIG. 17) connecting the outer surfaces of the base portion 23, and in this state, two places about 1/3 from both ends in the longitudinal direction are formed on the substrate 21. The binding band 7 is looped around from the top plate 6 to the top plate 6 to be united together. Thereafter, although not shown, the whole is wrapped in a film-like sheet (such as a wrap) to produce a solar cell module package. Then, the solar cell module package produced in this way is loaded into a transport container by a fork reel and transported to a destination.

JP 2010-168045 A

  Here, the number of solar cell modules packed as a solar cell module package is about 25 to 30. The reason is that if one pack is made with a larger number of sheets than this, it becomes difficult to transport with a general size forklift.

  For this reason, the conventional solar cell module package has a problem that the height is less than half that of a transportation container such as a truck, and the transportation efficiency is poor.

  In order to solve such a problem, the above-mentioned solar cell module package may be stacked and loaded to the full height of the transport container. However, the conventional solar cell module loader is arranged in multiple stages. Since they are not stacked, even if they are stacked, there is a high possibility that they will slip or collapse due to vibration or impact during transportation, and the solar cell module may be damaged.

  The present invention was devised to solve such problems, and an object of the present invention is to provide a solar cell module mounting unit that can stack and transport solar cell module packages without shifting or collapsing the load. There is to do.

A solar cell module stacker provided with support members that respectively support the corner portions of the solar cell modules that are arranged and stacked horizontally, a stacking member that is disposed at the upper end of the support member, and the stacking member And a fixing member for fixing the solar cell module stackers stacked one above the other through the above.

  Thus, by fixing the solar cell module stacker with the fixing member, the solar cell module stacker can be stacked in a plurality of stages in the vertical direction. Thereby, the transport efficiency (loading efficiency to a transport container) at the time of transport by a transport container etc. can be improved.

Moreover, in the solar cell module stacking unit of the present invention, the fixing member is configured to fix the substrates stacked vertically. Thus, by fixing the substrates, even when the solar cell module stackers are stacked in a plurality of stages, the solar cell module stackers can be stably and firmly fixed.
In the solar cell module loading unit of the present invention, a bracing member is used as the fixing member. By using the bracing member, the upper solar cell module stacking tool and the lower solar cell module stacking tool can be firmly fixed without shifting or collapsing.

  In the solar cell module stacking unit of the present invention, the solar cell module stacker integrally binds the top plate disposed on the topmost stacked solar cell module and the substrate to the top plate. And a binding member to be further provided. A solar cell module mounting tool in which solar cell modules are stacked and stacked in multiple layers by arranging a top plate on the uppermost solar cell module and binding the bottom substrate to the top plate together by a binding member Can be tightly packed without the solar cell module being displaced or collapsed.

  According to the solar cell module stacking unit of the present invention, the solar cell module stackers are stacked in multiple stages, and the upper and lower solar cell module stackers are fixed to each other by the fixing member, thereby stacking the solar cell module stackers in a plurality of stages. Can do. Thereby, since the solar cell module can be loaded up to the height of the transport container, the transport efficiency of the solar cell module can be improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is an overall perspective view showing a schematic configuration of a solar cell module stacking unit according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of a solar cell module stacker constituting the solar cell module mounting unit according to the present embodiment. 3 is a side view showing a state in which the top plate is arranged and packed in the solar cell module mounting tool, and FIG. 4 is a cross-sectional view taken along the line AA in FIG.

  First, the solar cell module stacker according to this embodiment will be described with reference to FIGS.

  The solar cell module stacker 2 according to the present embodiment is disposed at four corners of the rectangular substrate 21 and each corner of the substrate 21 and supports the corner portions 10a of the solar cell modules 10 stacked horizontally. The support members 22 and the outer surfaces of the support members 22 that are disposed on the stacked uppermost solar cell modules 10 and disposed at both corner portions 10a along one set of edge portions 10b of the solar cell modules 10 The top plate 6 has a bending portion 61 that bends along a straight line connecting the two, and a binding band 7 (see FIG. 3) that is a binding member that binds the substrate 21 to the top plate 6 together.

  Incidentally, such a configuration itself is the same as the configuration of FIG. 17 and FIG. 18 described in the prior art. Therefore, the solar cell modules 10 are stacked in multiple stages using the solar cell module stacker 2 of the present embodiment. The procedure for packing together is also the same as the procedure shown in FIGS. 9 to 18 described in the prior art. Therefore, the same reference numerals are given to the same members, and detailed description thereof is omitted.

  According to the above configuration, as shown in FIGS. 2 and 3, the bent portion 61 of the top plate 6 can be bent along the outer surface of the support member 22 (that is, the outer surface of the base portion 23).

  The solar cell module stacking unit 1 shown in FIG. 1 is used when stacking the solar cell module packages packed as described above in multiple stages.

  That is, the solar cell module stacking unit 1 of the present embodiment includes the solar cell module packing tool 2 having the above-described configuration (however, in FIG. 1, the top plate 6 and the binding band 7 are not shown), the sun. A stacking member 3 for stacking battery module packages in multiple stages and a bracing rod 4 as a fixing member for fixing the upper and lower solar cell module stackers 2 are provided. The stacked member 3 is used to ensure the strength of the support member 22 when the solar cell module package is stacked up and down. In addition, the bracing bar 4 is used to prevent lateral displacement and collapse of the solar cell module package stacked in multiple stages.

  That is, by fixing the solar cell module loaders 2 with the bracing bars 4, the solar cell module loaders 2 can be stacked in a plurality of levels in the vertical direction. Transport efficiency can be improved.

  The stacked member 3 is a metal plate (iron plate) formed in a rectangular shape. This stacking member 3 includes contact surfaces of the solar cell module packages stacked in the vertical direction (specifically, the uppermost support member 22 of the lower solar cell module package and the upper solar cell module package). The purpose is to reinforce the contact portion with the lower surface of the substrate 21.

  The bracing bar 4 fixes the substrates 21 of the solar cell module stacker 2 stacked one above the other. More specifically, the horizontal rail 21c arranged at one end (the left end in FIG. 1) of the substrate 21 of the upper solar cell module stacker 2 and the other of the substrates 21 of the lower solar cell module stacker 2 Is fixed obliquely by the brace bar 4 with the crosspiece 21c arranged at the end (right end in FIG. 1). A pair of the bracing bars 4 may be arranged on both sides in the width direction of the solar cell module package stacked in multiple stages, or arranged only on one side (in FIG. 1, only on the front side). May be. By fixing the substrates 21 in this manner, each solar cell module stacker 2 can be stably and firmly fixed even when the solar cell module stackers 2 are stacked in a plurality of stages.

  Next, a procedure for stacking solar cell module packages in two stages using the solar cell module stacking unit 1 having the above configuration will be described with reference to FIGS.

  FIG. 5 shows a solar cell module package packaged by the procedure shown in FIGS. 9 to 18 described in the prior art.

  In the state shown in FIG. 5, the stacked members 3 are disposed at the positions of the uppermost support members 22 disposed at the four corners.

  Thereafter, as shown in FIG. 6, the upper solar cell module package is stacked on the lower solar cell module package via the stacking member 3.

  Next, as shown in FIG. 7, the braces 4 are used to fix the substrates 21 of the solar cell module stacker 2 stacked one above the other. That is, the horizontal beam 21c disposed at one end of the substrate 21 of the upper solar cell module stacker 2 and the horizontal beam 21c disposed at the other end of the substrate 21 of the lower solar cell module stacker 2. Are fixed obliquely by the brace bar 4.

  At this time, as described above, the bent portion 61 of the top plate 6 is bent along the outer surface of the base portion 23 of the support member 22 and does not swell laterally. It is possible to bind 61 by slightly pushing 61 toward the edge 10b of the solar cell module 10. Therefore, when the end portion of the bracing bar 4 is fixed to the end portion of the substrate 21, the bent portion 61 of the top plate 6 can be fixed without getting in the way. Further, since the bent portion 61 is not obstructed, the problem that the bracing bar 4 is pushed by the bent portion 61 of the top plate 6 and bulges out (curves) does not occur.

  Thereby, the solar cell module package can be stacked in two upper and lower stages with a structure that can sufficiently withstand vibration and shock during transportation. Moreover, the loading efficiency to the transport container is improved by loading in two upper and lower stages.

  In the above embodiment, the support member 22 is described as being configured to be stacked one by one in correspondence with the solar cell module 10, but these are integrated in a plurality of stages (for example, five stages, etc.). Alternatively, the whole may be integrated as one support member.

  In the above embodiment, the stacked members 3 are used. However, if there is no problem in strength, the stacked members 3 can be omitted.

  In the above embodiment, the bracing bar 4 is slanted in one direction, but two bars may be slung. As a result, the strength is further increased, and a stacking structure that is strong against rolling and pitching can be obtained.

  In addition, embodiment disclosed this time is an illustration in all the points, Comprising: It does not become the basis of limited interpretation. Therefore, the technical scope of the present invention is not interpreted only by the above-described embodiments, but is defined based on the description of the scope of claims. Moreover, all the changes within the meaning and range equivalent to a claim are included.
