  The solar cell module stacking tool 100 according to the present invention is suitably used for multi-stage stacking in which solar cell modules 3 having a frameless structure without an aluminum frame member are stacked horizontally in multiple stages. Therefore, in the following embodiment, the case where the solar cell modules 3 having a frameless structure are stacked in multiple stages will be described. In the solar cell module package according to the present invention, the solar cell modules 3 are stacked horizontally in multiple stages by the solar cell module stacker 100.

-First embodiment-
FIG. 1 is an overall perspective view showing an example (first embodiment) of a solar cell module stacking tool 100. An arrow Z in FIG. 1 indicates the vertical direction. As shown in FIG. 1, the solar cell module stacker 100 includes a support member 1 and a pallet 2. The support member 1 has a lower surface engaged with the pallet 2 and supports the four corners of the solar cell module 3. As will be described later with reference to FIG. 2, the support member 1 is fixed to four corners of the pallet 2, and the four corners are supported by the base portion 11 or the support portion 15 formed on the support member 1. 3 are stacked horizontally in multiple stages.

  Next, the structure of the support member 1 and the pallet 2 will be described in detail with reference to FIGS. FIG. 2 is a partial perspective view of the support member 1 and the pallet 2 shown in FIG. 3 is a bottom view and a side view of the support member 1 shown in FIG. FIG. 3A is a bottom view of the support member 1, and FIG. 3B is a side view of the support member 1. FIG. 4 is a plan view and a side view of the pallet 2 shown in FIG. FIG. 4A is a plan view of the pallet 2, and FIG. 4B is a side view of the pallet 2.

-Structure of pallet 2-
First, the structure of the pallet 2 will be described with reference to FIGS. As shown in FIG. 4, the pallet 2 is made of wood and has a frame structure in which four quadrangular columnar members are combined. In addition, a recess 21 is formed at each of the four corners of the pallet 2. The concave portion 21 is a portion in which the fitting convex portion 13 (see FIG. 2) of the support member 1 is fitted and locked, and as shown in FIG. It may be formed in a quadrangular pyramid shape. Further, the recess 21 is formed so as to penetrate the pallet 2 in the vertical direction.

  Thus, since the pallet 2 has a frame structure in which four quadrangular columnar members are combined, the pallet 2 can be realized with a simple configuration. Further, since the pallet 2 is made of wood, the pallet 2 having the required strength can be produced at a relatively low cost. Furthermore, since the concave portion 21 of the pallet 2 is formed so as to penetrate the pallet 2 in the vertical direction, the concave portion 21 of the pallet 2 can be easily formed.

-Structure of support member 1-
Next, the structure of the support member 1 will be described with reference to FIGS. 2 and 3. The support member 1 includes a base portion 11, a restriction portion 12, a fitting convex portion 13, a locking portion 14, a support portion 15, and a countersunk screw 16. The support member 1 is made of resin and is integrally formed.

  In this way, since the support member 1 is made of resin and is integrally formed, the support member 1 has the required strength and is less likely to damage the solar cell module 3 due to sliding, contact, or the like. Can be produced relatively inexpensively.

  Although this embodiment demonstrates the case where the supporting member 1 is resin, the form which consists of other materials (for example, rubber | gum etc.) may be sufficient as the supporting member 1. FIG.

  The base portion 11 is a plate-like member that is supported in contact with the upper surface of the pallet 2 and supports the lower surface of the corner portion of the solar cell module 3 placed on the lowest side (side adjacent to the pallet 2). . Further, the base body portion 11 is formed with two screw holes 111 through which the countersunk screws 16 are inserted.

  The screw holes 111 are connected to the base part 11 and the restricting part 12 (the right end position and the lower end position in FIG. 3A), and to the base part 11 and the locking part 14 in the connecting position (upper left in FIG. 3A). End position and left end position). The countersunk screw 16 passes through the screw hole 111 and is screwed into the pallet 2 to fix the base portion 11 to the pallet 2.

  The restricting portion 12 is a plate-like member that is erected upward at the outer peripheral side end portion of the base portion 11 and restricts the horizontal movement of the corner portion of the solar cell module 3. As shown in FIG. 2, the restricting portion 12 includes a first restricting portion 121 and a second restricting portion 122 that are orthogonal to each other. The 1st control part 121 and the 2nd control part 122 are integrally molded by planar view L shape. Further, the first restricting portion 121 and the second restricting portion 122 are extended so as to protrude more than a predetermined length (for example, 50 mm) from the upper surface of the uppermost support portion 15 of the support portion 15.

  Thus, since the 1st control part 121 and the 2nd control part 122 are integrally molded by planar view L shape, the intensity | strength of the control part 12 is securable with a simple structure. Moreover, since the 1st control part 121 and the 2nd control part 122 are extended so that more than predetermined length (for example, 50 mm) may protrude from the upper surface of the support part 15 of the uppermost end among the support parts 15. FIG. Even when the solar cell module 3 placed on the upper surface of the uppermost support portion 15 vibrates, the horizontal movement of the corner portion of the solar cell module 3 is surely restricted by the restriction portion 12. Can do.

  The fitting convex portion 13 is a quadrangular frustum-shaped member that is erected downward at a substantially central position of the base body portion 11 and is fitted and locked to the concave portion 21 formed in the pallet 2. Here, the fitting convex part 13 is corresponded to the "convex part" as described in a claim. Since the fitting convex portion 13 erected downward at a substantially central position of the base portion 11 is fitted and locked to the concave portion 21 formed on the pallet 2, the base portion 11 is moved in the horizontal direction. Is regulated. Moreover, the fitting convex part 13 and the recessed part 21 are formed in the shape of a truncated pyramid, so that it goes below.

  In this way, the lower surface of the corner portion of the solar cell module 3 placed on the lowermost side is supported by the base portion 11 of the support member 1, and the solar cell module 3 is horizontal by the restriction portion 12 of the support member 1. Directional movement is restricted. Since the fitting convex portion 13 of the supporting member 1 that supports the solar cell module 3 and restricts the movement in the horizontal direction is fitted and locked to the concave portion 21 of the pallet 2 in this manner, Generation | occurrence | production of the load collapse of the solar cell module 3 mounted can be prevented.

  Moreover, since the fitting convex part 13 and the recessed part 21 are formed in the shape of a tapered truncated pyramid so that it goes down, the fitting convex part 13 can be easily inserted and fitted in the recessed part 21. In addition, the base portion 11 of the support member 1 can be effectively restricted from rotating about the fitting convex portion 13.

  In this embodiment, although the case where the fitting convex part 13 and the recessed part 21 were formed in the shape of a quadrangular frustum was demonstrated, as the fitting convex part 13 and the recessed part 21 headed below, the shape of a truncated cone is tapered. (Or a conical shape) may be used. In this case, the fitting convex portion 13 can be more easily inserted and fitted into the concave portion 21.

  The locking portion 14 is a member that is locked in contact with two adjacent surfaces on the inner peripheral side of the pallet 2. Specifically, the locking portion 14 includes two plate-like members 141 and 142 that are locked in contact with two adjacent surfaces on the inner peripheral side of the pallet 2. Furthermore, the two plate-like members 141 and 142 of the locking portion 14 are integrally formed in a substantially L shape in plan view.

  In this way, the locking portion 14 erected downward at the inner peripheral side end portion of the base body portion 11 is brought into contact with the inner surface of the pallet 2 and locked, so that the horizontal direction of the support member 1 is increased. Directional movement can be more reliably regulated. Further, since the two plate-like members 141 and 142 of the locking portion 14 are respectively brought into contact with and locked with two adjacent surfaces on the inner peripheral side of the pallet 2, the horizontal movement of the support member 1 is performed. Can be more reliably regulated. Furthermore, since the two plate-like members 141 and 142 of the locking portion 14 are integrally formed in a substantially L shape in plan view, the strength of the locking portion 14 can be ensured.

  In the present embodiment, the case where the four support members 1 fixed to the four corners of the pallet 2 are each provided with a locking portion 14 will be described, but at least one of the four support members 1 is used. One support member 1 may be provided with a locking portion 14.

  Moreover, in this embodiment, although the latching | locking part 14 is provided with the plate-shaped members 141 and 142, the latching | locking part 14 is two surfaces adjacent to the inner peripheral side of the pallet 2, for example. The form which is a rod-shaped member arrange | positioned in this intersection point position may be sufficient.

  The support portion 15 is erected in parallel with the upper surface of the base portion 11 on the restricting portion 12 and supports one lower surface of the corner portion of the solar cell module 3 excluding the solar cell module 3 placed on the lowermost side. A plurality of (10 pieces in FIG. 2) plate-like members. If the number of support portions 15 is N, a maximum of (N + 1) solar cell modules 3 can be placed.

  That is, the lower surface of the corner portion of the solar cell module 3 is supported by one or a plurality of plate-like support portions 15 erected on the restriction portion 12 in parallel with the upper surface of the base body portion 11. And since the control part 12 is extended toward upper direction, the horizontal movement of the corner | angular part of the solar cell module 3 supported by the support part 15 is controlled. Therefore, it is possible to prevent the collapse of the solar cell module 3 supported by the base portion 11 and the solar cell module 3 supported by the support portion 15.

  In the present embodiment, a case where ten support parts 15 are formed will be described, but any form in which one or more support parts 15 are formed may be used. Moreover, although this embodiment demonstrates the case where the support part 15 is a rectangular plate-shaped member, the shape of the support part 15 may be shapes other than a rectangle. For example, it may be a partial arc.

  The countersunk screw 16 passes through the screw hole 111 and is screwed into the pallet 2 to fix the base portion 11 to the pallet 2. Thus, since the base | substrate part 11 is fixed to the pallet 2 with the countersunk screw 16, the horizontal movement of the supporting member 1 can be controlled still more reliably.

  In this embodiment, the case where the countersunk screw 16 fixes the base part 11 to the pallet 2 will be described. However, the base part 11 may be fixed to the pallet 2 by at least one of the countersunk screw 16 or the countersunk screw.

  Further, as shown in FIG. 3, the support member 1 includes a corner portion of the base portion 11 that supports the corner portion of the solar cell module 3 (the lower right end of FIG. 3A) and the vertical direction of the fitting convex portion 13. The plane is symmetrical with respect to a plane including the central axis (a plane indicated by a one-dot chain line in FIG. 3A).

  Thus, since the supporting member 1 is comprised by plane symmetry, since the supporting member 1 which supports each four corner | angular parts of the solar cell module 3 can be implement | achieved by the same structure, a supporting member 1 can be reduced in cost, and convenience can be improved.

-Loading procedure using solar cell module mounting tool 100-
A procedure for horizontally stacking the solar cell modules 3 in multiple stages on the pallet 2 using the solar cell module stacking tool 100 described above with reference to FIGS. First, the fitting convex portions 13 of the support member 1 are inserted into the concave portions 21 of the pallet 2 at two adjacent sides of the pallet 2. Next, the countersunk screw 16 is inserted into the screw hole 111 and screwed into the pallet 2. In this way, the support member 1 is fixed on the pallet 2.

  Next, two adjacent sides of a plurality (for example, 10) of solar cell modules 3 are respectively placed on the upper surfaces of the base portion 11 and the support portion 15 of the two support members 1 fixed on the pallet 2. To do. At this time, the other two sides of the solar cell module 3 are supported by a fork or the like of the device.

  Then, the remaining two sides of the solar cell module 3 are respectively placed on the upper surfaces of the base portion 11 and the support portion 15 of the two support members 1, and the fitting convex portions 13 of the two support members 1 are placed on the pallet 2.

  In this way, a plurality of (for example, 10) solar cell modules 3 can be stacked horizontally and stacked on the pallet 2. In the placement procedure described above, the two support members 1 are not fixed to the pallet 2 with the countersunk screws 16, but not all the support members 1 are necessarily fixed to the pallet 2 with the countersunk screws 16.

-Second embodiment-
FIG. 5 is an overall perspective view showing an example (second embodiment) of the solar cell module stacking tool 100A. The solar cell module stacking tool 100A shown in FIG. 5 is different from the solar cell module stacking tool 100 shown in FIGS. 1 to 4 in the following points. In the solar cell module stacking tool 100 shown in FIGS. 1 to 4, the support member 1 includes a support portion 15 for mounting a plurality of solar cell modules 3, but the solar cell module stacking tool shown in FIG. 5. The support member 1A according to 100A is different in that it does not have a support portion. In FIG. 5, a member corresponding to the support member 1 of the solar cell module stacker 100 is indicated by adding “A” to the end of the reference numeral provided in the support member 1.

  That is, the solar cell module stacker 100 is capable of mounting a maximum of (N + 1) solar cell modules 3 when the number of support portions 15 is N, whereas the solar cell module stacker 100 100A mounts one solar cell module 3.
