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

[Embodiment 1]
FIG. 1 is a perspective view showing a state before final packing of a solar cell module using the support structure 1 according to the embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along the line BB of FIG.

The support structure 2 shown in FIG. 1 and FIG. 2 is a component of a stacked packing tool for stacking and packing solar cell modules in a horizontal state, and the stacked packing tool is roughly divided into a rectangular substrate portion. (Hereinafter also referred to as a pallet) 1 and a support structure that is arranged at each of the four corners of the upper surface of the substrate unit 1 and supports the solar cell module 100 in a horizontal state by placing the corners 100a of the solar cell module 100. And a body 2.

The support structure 2 is configured so that the solar cell modules 100 are stacked and packed in a horizontal state. Four support structures 2 are attached to the upper surface of the pallet 1. The four support structures 2 are positioned with respect to the pallet 1. The four support structures 2 support the four corners (corner portions) 100a of the rectangular solar cell module 100, respectively.

Further, a plurality of (eight in the example of FIG. 1) support structures 2 are stacked in the vertical direction Z on the four support structures 2 attached to the upper surface of the pallet 1. One solar cell module 100 is supported by the four support structures 2 at each stage. That is, in the example of FIG. 1, eight solar cell modules 100 are stacked on the pallet 1 in a horizontal state.

In addition, the solar cell module 100 stacked on the pallet 1 is covered with a top plate 6 to be described later and the upper surface of the uppermost solar cell module 100 is covered with a binding band 7 such as a PP (polypropylene) band as a binding member. It is transported while being wound around the pallet 1.

Moreover, the solar cell module 100 supported by the support structure 2 is frameless. In other words, the frameless solar cell modules 100 can be stacked and packed by the support structure 2 in multiple stages.

FIG. 3A is a perspective view of the support structure 2 as viewed obliquely from above, and FIG. 3B is a perspective view of the support structure 2 as viewed from obliquely below.

The support structure 2 is a structure that receives the corner portion 100a of the solar cell module 100 from below, and a base portion 23 that is bent in an L shape in plan view, and an inner wall surface (inner side surface) 23c of the base portion 23. And a quadrangular receiving portion (supporting portion) 28 extending in a direction perpendicular to the wall surface from the lower end portion.

The receiving portion 28 is formed so as to receive the corner portion 100a of the solar cell module 100 from below, and the overall shape of the support structure 2 is formed in a substantially L-shaped longitudinal section.

The lower surface of the receiving portion 28 is flush with the lower end surface 23 b of the base portion 23. As described above, when the lower surface of the support structure 2 is constituted by the lower surface of the receiving portion 28 and the lower end surface 23b of the base portion 23, when the support structure 2 is placed on the pallet 1, Since the support structure 2 comes into contact with the pallet 1 both at the lower surface and the lower end surface 23b of the base portion 23, the support structure 2 can be placed on the pallet 1 in a more stable state.

A fitting recess 29 for fitting with the fitting protrusion 1 a formed on the upper surface of the pallet 1 is formed on the lower surface of the receiving portion 28.

In this manner, the fitting convex portion 1 a is formed on the upper surface of the pallet 1, and the fitting concave portion 29 is formed on the lower surface of the receiving portion 28 of the supporting structure 2, thereby placing the supporting structure 2 on the pallet 1. When this is done, the lateral displacement of the support structure 2 can be prevented by this fitting structure.

The base portion 23 is configured to be stacked in the vertical direction Z. For this reason, the engaging convex portion 25 and the engaging portion 25 are engaged with the upper end surface 23a and the lower end surface 23b of the base portion 23 so as to be sequentially fitted and engaged with the base portion 23 of another support structure 2 arranged adjacent to each other in the vertical direction. Recesses 26 are respectively provided. Two engaging convex portions 25 are provided on each upper end surface 23a of each piece of the base portion 23, and two engaging concave portions 26 are provided on each lower end surface 23b of each piece of the base portion 23. A total of two are provided. However, the number of formation of the engaging convex part 25 and the engaging concave part 26 is not limited to this.

For example, as shown in FIG. 4A and FIG. 4B, four engagement protrusions 25 are provided on the upper end surface 23 a of each piece of the base portion 23, for a total of four engagement protrusions 26, A total of four pieces may be provided, two on the lower end surface 23b of each piece of the base portion 23. In addition to this, for example, a configuration in which two L-shaped one in total are provided on the upper end surface 23a and the lower end surface 23b of the base portion 23, respectively. With such an engagement structure, the support structure 2 can be stacked in multiple stages while preventing lateral displacement.

Here, in the present embodiment, the engaging recess 26 has a structure in which the outer wall surface (outer side surface) 23d side of the base portion 23 is opened. As described above, the engagement recess 26 has a structure in which the outer wall surface 23d side of the base portion 23 is opened, so that the engagement state between the support structures 2 arranged adjacent to each other in the vertical direction can be directly confirmed visually. it can.

Further, as shown in FIG. 5, when engaging the engaging concave portion 26 of the supporting structure 2 disposed on the upper side with the engaging convex portion 25 of the lower supporting structure 2, only from the upper direction d1. In addition, since the engaging concave portion 26 can be fitted and engaged with the engaging convex portion 25 even from the lateral direction d3 or the diagonally upward direction d2, the engaging operation is facilitated.

Further, the outer wall surface (outer side surface) 25 a of the engaging convex portion 25 is formed flush with the outer wall surface 23 d of the base body portion 23. In this way, the outer wall surface 25a of the engagement convex portion 25 is formed flush with the outer wall surface 23d of the base portion 23, so that the engagement convex portion 25 of the lower support structure 2 is disposed on the upper side. When the engaging concave portion 26 of the supporting structure 2 is engaged, the outer wall surface 25a of the engaging convex portion 25 of the lower supporting structure 2 is the outer wall surface 23d of the base portion 23 of the upper supporting structure 2. And become the same. Therefore, it can be easily confirmed that the lower support structure 2 and the upper support structure 2 are reliably engaged by visually confirming that they are flush.

The support structure 2 having such a shape is formed by injection molding using a resin such as PP (polypropylene) or ABS (acrylonitrile / butadiene / styrene copolymer).

When the pallet 1 is made of wood, the fitting convex portion 1a is formed by cutting the pallet 1 itself or by forming a piece of wood, and bonding the piece of wood onto the pallet 1 and firmly fixing it with screws, nails or the like. do it. In addition, when the pallet 1 is made of iron, the fitting convex portion may be formed by burring processing in which a hole is formed by burring and then processed so as to push up the periphery of the hole.

The substrate unit 1 has a two-layer structure in which an upper substrate 11 and a lower substrate 12 are supported by a plurality of horizontal rails 13, and there is a gap between the upper substrate 11 and the lower substrate 12. A hole through which a binding band 7 described later is passed, and a hole into which a fork of a forklift is inserted when loading into a transport container or the like.

Next, a packing method for stacking and packing the solar cell modules 100 in multiple stages using the support structure 2 having the above configuration will be described with reference to FIGS. The following packing method is performed by, for example, an automatic machine.

First, as shown in FIG. 6, fitting recesses 29 formed on the lower surface of the receiving portion 28 of the support structure 2 in the first stage are fitted into the four fitting projections 1 a of the substrate portion 1. Thus, the first-stage support structures 2 are arranged at the four corners of the substrate unit 1. Next, as shown in FIG. 7, the four corner portions 100 a of the first-stage solar cell module 100 are placed on the first-stage support structures 2. Next, as shown in FIG. 8, the engagement concave portions 26 of the second-stage support structure 2 are fitted and engaged with the engagement convex portions 25 of the first-stage support structure 2. Next, as shown in FIG. 9, the corners 100 a at the four corners of the second-stage solar cell module 100 are placed on the second-stage support structures 2. Thereafter, by repeating the procedure shown in FIGS. 8 and 9 a predetermined number of times, as shown in FIG. 1, a predetermined number of solar cell modules 100 are stacked in multiple stages on the substrate unit 1.

In the embodiment, the corner portion 100a of the solar cell module 100 includes the upper surface of the receiving portion 28 of the support structure 2 that supports the corner portion 100a of the solar cell module 100 and the support structure disposed on the upper stage thereof. It is configured to be sandwiched between the lower surface of the two receiving portions 28. Thereby, it is possible to prevent the individual solar cell modules 100 from flapping up and down (vertical direction Z).

Thereafter, as shown in FIG. 10, the solar cell module 100 is prevented from bending up and down at the center of both edge portions 100 b along the longitudinal direction of the stacked solar cell modules 100, and is caused by vibration during transportation. A shock-absorbing member 5 for preventing vertical flapping is fitted and arranged.

As shown in FIG. 11, the buffer member 5 is formed in a U shape when viewed from the side. As shown in FIG. 12, the buffer member 5 is fitted to the edge portion 100 b of each solar cell module 100, so that the upper and lower buffer members are arranged. 5 is arranged without a gap.

Further, the buffer member 5 is formed with a concave groove portion 53 penetrating vertically on the outer side surface through which a binding band 7 which is a binding member described later is passed.

Therefore, as shown in FIG. 13, first, in this state, the substrate member 1 (more specifically, the upper substrate 11) is passed through the concave groove portion 53 of the buffer member 5 to the uppermost solar cell module 100. Is wound around the binding band 7 and bound together.

Thus, by forming the concave groove portion 53 through which the binding band 7 is passed on the outer side surface of the buffer member 5, it is possible to prevent the buffer member 5 after binding from shifting in the lateral direction.

Next, as shown in FIG. 14, a top plate 6 made of, for example, cardboard is formed on the upper surface of the uppermost solar cell module 100 as a buffer so as to be wider than the width of the solar cell module 100.

The top plate 6 has a bent portion 61 that bends along a straight line L that connects the outer wall surfaces of the support structure 2 disposed at the corner portions 100a on both sides of the edge portion 100b along the longitudinal direction of the solar cell module 100. ing.

And as shown in FIG. 15, the bending part 61 of the both sides of the longitudinal direction of the top plate 6 is bend | folded below along the straight line L which connects the outer side wall surfaces of the support structure 2. As shown in FIG.

Then, in this state, the binding band 7 is routed from the substrate portion 1 (more specifically, the upper substrate 11) to the top plate 6 at two places about 1/3 from both ends in the longitudinal direction. And unite them together.

After this, although not shown in the drawing, the whole is wrapped in a film-like sheet (such as a wrap) to produce a solar cell module package. And the solar cell module package produced in this way is loaded into a transport container by a forklift and transported to a destination.

As described above, the support structure according to Embodiment 1 is a support structure that places the corners of the solar cell module and supports the solar cell module in a horizontal state, and is stacked in the vertical direction.

A feature is that an outer side surface of the base portion is opened.

Further, according to the above support structure, the outer side surface of the engaging convex portion may be formed to be flush with the outer side surface of the base portion.

In this manner, the outer side surface of the engaging convex portion is formed flush with the outer side surface of the base portion so as to be arranged on the upper side of the engaging convex portion of the lower support structure. When the engagement concave portion of the support structure is engaged, the outer side surface of the engagement convex portion of the lower support structure is flush with the outer side surface of the base portion of the upper support structure. Therefore, it can be easily confirmed that the lower support structure and the upper support structure are reliably engaged by visually confirming that they are flush.

[Embodiment 2]
FIG. 25 is a perspective view showing a state before final packing of the solar cell module using the stacked packing tool A according to the embodiment of the present invention. With reference to FIG. 25, the outline of the loading packaging tool A before final packing is demonstrated.

The stacking packing tool A shown in FIG. 25 is a stacking packing tool for stacking and packing solar cell modules in a horizontal state. When roughly classified, the stacking packing tool A stands at four locations on the rectangular substrate portion 1 and the upper surface of the substrate portion 1.

A buffer member 5 that holds the solar cell module 100 by being fitted to the edge portion 100b from the lateral direction.

Thus, the buffer member 5 is fitted to the pair of opposing edge portions 100b of the solar cell module 100 from the lateral direction, so that the edge portion 100b of the solar cell module 100 is fixed from both sides by the pair of buffer members 5. can do. This prevents the solar cell modules 100 stacked in a horizontal state from being bent due to vibration during transportation, prevents contact or collision with the solar cell modules 100 adjacent in the vertical direction, and further due to vibration during transportation. The horizontal movement of the solar cell module 100 can be suppressed.

The substrate unit 1 (hereinafter also referred to as a pallet) has a two-layer structure in which an upper substrate 11 and a lower substrate 12 are supported by a plurality of horizontal rails 13. Is a hole through which a bundling member 7 (hereinafter also referred to as a bundling band), which will be described later, passes, and a hole into which a fork of a forklift is inserted when loading into a transport container or the like. Further, at the four corners of the upper surface of the upper substrate 11, fitting protrusions 1a are formed as shown in FIG.

The support structure 2 is configured so that the solar cell modules 100 are stacked and packed in a horizontal state. Four support structures 2 are attached to the upper surface of the upper substrate 11 (hereinafter also referred to as the upper surface of the pallet). The four support structures 2 are fitted and positioned on the fitting projections 1 a on the pallet 1. The four support structures 2 each support four corners 100a (corner portions) of the rectangular solar cell module 100.

Further, a plurality of (9 in the example of FIG. 25) support structures 2 are further stacked in the vertical direction Z on the four support structures 2 attached to the upper surface of the pallet 1. One solar cell module 100 is supported by the four support structures 2 at each stage. That is, in the example of FIG. 25, ten solar cell modules 100 are stacked on the pallet 1 in a horizontal state.

FIG. 16A is a perspective view of the support structure 2 as viewed obliquely from above, and FIG. 16B is a perspective view of the support structure 2 as viewed from obliquely below.

The support structure 2 is a structure that receives the corner portion 100a of the solar cell module 100 from below, and the base portion 23 that is bent in an L shape in plan view, and the wall surface from the lower end portion of the inner wall surface of the base portion 23. And a rectangular receiving portion 28 (supporting portion) extending in a direction perpendicular to the vertical direction.

For example, as shown in FIGS. 17A and 17B, two engagement convex portions 25 are provided on the upper end surface 23 a of each piece of the base portion 23, for a total of four, and the engagement concave portions 26 are also provided on the base portion 23. It is good also as a structure which provided two in total at the lower end surface 23b of one piece. With such an engagement structure, the support structure 2 can be stacked in multiple stages while preventing lateral displacement.

Further, as the support structure 2 in Embodiment 2, the support structure 2 shown in FIGS. 3A and 3B or the support structure 2 shown in FIGS. 4A and 4B may be used.

FIG. 18 is a perspective view of the buffer member 5 as viewed obliquely from above.

The shock-absorbing member 5 has a U-shape when viewed from the side, and includes an opening 54 (opening groove) formed in a U-shape. The opening 54 (opening groove) is formed to be fitted to the edge 100b of the solar cell module 100. Further, the upper surface 55 and the lower surface 56 of the buffer member 5 are flat. Thereby, the some buffer member 5 can be stacked | piled up and down, and the upper surface of the buffer member 5 and the lower surface of another buffer member 5 can be adhere | attached using an adhesive agent, an adhesive tape, etc. Further, a concave groove 53 is vertically formed through the side surface (outer surface) opposite to the opening 54. Thereby, the later-described binding band 7 (binding member) can be passed through the concave groove portion 53 on the outer surface of the buffer member 5, and the lateral displacement of the buffer member 5 after binding can be prevented. In addition, although it is preferable to pass the binding band 7 by forming the concave groove portion 53, the concave groove portion 53 may not be formed.

The buffer member 5 having such a shape is made of, for example, foamed plastic or foamed urethane.

FIG. 19 is a perspective view of another buffer member 5 as viewed obliquely from above.

The buffer member 5 includes a plurality of openings 54 (opening grooves) at regular intervals in the vertical direction. Each opening 54 is formed so as to be fitted to the edge 100b of the solar cell module 100. In the illustrated example, two openings 54 are provided. As a result, a plurality of stacked solar cell modules 100 can be held by one buffer member 5. Further, since the number of the buffer members 5 to be bonded and used is smaller than that of the buffer member 5 in which one opening 54 is formed, the number of times of bonding between the buffer members 5 can be reduced. The strength can be improved.

FIG. 20 is a perspective view of still another buffer member 5 as viewed from obliquely above.

The buffer member 5 has a tapered surface that guides the edge 100b of the solar cell module 100 at the opening tip 57 of the opening 54 (opening groove) of the buffer member 5 shown in FIG. Thereby, the solar cell module can be efficiently guided to the opening 54 by the tapered surface provided at the opening tip 57 of the opening 54.

Next, a packing method for stacking and packing the solar cell modules 100 in multiple stages using the stacked packing tool A having the above configuration will be described with reference to FIGS. The following packing method is performed by, for example, an automatic machine.

First, as shown in FIG. 21, the fitting concave portions 29 formed on the lower surface of the receiving portion 28 of the support structure 2 in the first step are respectively provided on the four fitting convex portions 1 a of the substrate portion 1. The first-stage support structure 2 is disposed by fitting into the fitting convex portion 1a formed on the upper surface of the first stage.

Next, as shown in FIG. 22, the four corners 100 a of the first-stage solar cell module 100 are placed on the first-stage support structures 2. Next, as shown in FIG. 23, the engagement concave portions 26 of the second-stage support structure 2 are fitted and engaged with the engagement convex portions 25 of the first-stage support structure 2. Next, as shown in FIG. 24, the corners 100 a at the four corners of the second-stage solar cell module 100 are placed on the second-stage support structures 2. Thereafter, by repeating the procedure shown in FIGS. 23 and 24 a predetermined number of times, a predetermined number of solar cell modules 100 are stacked in multiple stages on the pallet 1.

After that, in order to prevent vertical deflection of the solar cell module 100 at the center of both edge portions 100b along the longitudinal direction of the stacked solar cell modules 100, and to prevent vertical fluttering due to vibration during transportation, etc. The buffer members 5 are fitted together from the lateral direction of the solar cell module 100 to hold the solar cell module (see FIG. 25).

FIG. 26 is a cross-sectional view taken along the line CC of FIG. In order to fit the buffer members 5 from the lateral direction to the opposing edge portions 100b of all the solar cell modules 100 stacked in a horizontal state in the vertical direction, the number of openings 54 equal to the number of the solar cell modules 100 in advance. Thus, the necessary number of buffer members 5 are prepared, and these buffer members 5 are divided into two parts and stacked so that the number of openings 54 is the same as the number of solar cell modules 100. And the adjacent upper surface and lower surface of the buffer member 5 stacked up and down are bonded using an adhesive or an adhesive tape, and in this state, the solar cell module 100 is stacked and integrally formed from the lateral direction. The buffer members 5 are fitted together to hold the opposite edge portions 100b of the solar cell module 100 from both sides.

At this time, the solar cell module 100 can be efficiently guided to the opening 54 by the tapered surface provided at the opening tip 57 of the opening 54 of the buffer member 5.

The buffer members 5 that are integrally formed by stacking in the vertical direction from the lateral direction of the solar cell module 100 are fitted together, and then the binding band 7 (binding member) is passed through the concave groove portion 53 on the outer surface of the buffer member 5 and the substrate. The part 1 (more specifically, the upper substrate 11) to the uppermost solar cell module 100 is wound around the binding band 7 and bound together.

As described above, by forming the concave groove portion 53 through which the binding band 7 (binding member) is passed on the outer surface of the buffer member 5, it is possible to prevent lateral displacement of the buffer member after binding.

Note that the shape of the lowermost buffer member 5 a is different from the shape of the other buffer members 5, and has a shape that contacts the upper surface of the pallet 1.

For example, a description will be given of the stacking packing tool A when the spacer member 3 is mounted on the four fitting protrusions 1a of the pallet 1 described above without mounting the support structure 2 (see FIG. 27). In addition, the structure of the stacking packaging tool A using the spacer member 3 will be described in more detail in a fourth embodiment described later. Here, the spacer member 3 has a cubic shape as shown in FIGS. 28A and 28B, and the lower surface placed on the pallet 1 has fitting convex portions formed at the four corners of the upper surface of the pallet 1. A fitting concave portion 31 to be fitted to 1a is formed, and a fitting convex portion 32 for fitting and fixing the support structure 2 is formed on the upper surface.

After the spacer members 3 are arranged on the four fitting protrusions 1a of the pallet 1, the support structures 2 are stacked on the spacer members 3 at the four corners, and the solar cell module is formed by the support structures 2 at the four corners. 100 corner portions 100a are placed so as to be placed thereon, and thereafter, the stacking of the support structure 2 and the placement of the solar cell modules are repeated a predetermined number of times, whereby a predetermined number of solar cell modules 100 are placed on the pallet 1 in multiple stages. To load. At this time, since the spacer member 3 is attached to the upper surface of the pallet 1 between the lowermost solar cell module 100 and the upper surface of the pallet 1, as shown in FIG. The distance between the lowermost solar cell module 100 and the upper surface of the pallet 1 is wider than the distance between. FIG. 29 shows a cross-sectional view of the solar cell module 100, the support structure 2, and the spacer member 3.

Thus, as shown in FIG. 30, the lowermost buffer member 5 a is different from the other buffer members 5 arranged on the upper stage in that the thickness T <b> 1 on the lower side of the opening 54 is different from that of the other buffer members 5. It is thicker than the thickness T2 on the lower side of the opening 54. Thus, by fitting the buffer member 5 having a shape that comes into contact with the upper surface of the pallet 1, both the upper surface of the pallet 1 and the lower surface of the lowermost solar cell module 100 are in contact with the buffer member 5a, and the solar cell module Since 100 is fitted with the buffer member 5a, contact or collision between the lowermost solar cell module 100 and the upper surface of the pallet 1 can be prevented. FIG. 30 is a cross-sectional view of the solar cell module 100 and the buffer member 5.

In addition, the shape of the uppermost buffer member 5b is such that the height from the upper surface of the pallet 1 to the upper surface of the uppermost buffer member 5b is equal to the height from the upper surface of the pallet 1 to the upper surface of the uppermost support structure 2. Is designed. That is, the height T11 (see FIG. 30) from the upper surface of the uppermost solar cell module to the upper surface 55 of the uppermost buffer member 5 is the upper surface of the uppermost support structure 2 from the upper surface of the uppermost solar cell module. Since it is equal to the height T11 up to (that is, the height to the engagement convex portion 25 (see FIG. 29)), the shape of the uppermost buffer member 5b is different from the shapes of the other buffer members 5.

Note that the shape of the uppermost buffer member 5b and the shape of the other buffer members 5 may be the same, and in this case, the engagement protrusion of the support structure 2 from the upper surface of the solar cell module 100 of each step. The height T11 to the portion 25 (see FIG. 29) and the height S (see FIG. 30) of the upper surface of the buffer member 5 from the upper surface of the solar cell module 100 at each stage are equal.

Accordingly, the height from the upper surface of the pallet 1 to the upper surface of the uppermost buffer member 5b is equal to the height from the upper surface of the pallet 1 to the upper surface of the uppermost support structure 2, so that the upper surface of the buffer member 5b and the support structure Even if a top plate 6 described later is placed on the upper surface of the body 2, the top plate 6 can be kept horizontal.

Here, an example of stacking of the buffer members 5 is shown in FIGS. The buffer member 5 may be stacked by vertically stacking the buffer member 5 having one opening 54 (opening groove) (see FIG. 30), or by stacking the buffer member 5 provided with a plurality of openings 54. It does not matter (see FIG. 31). Moreover, you may pile up combining the buffer member 5 provided with the one opening part 54, and the buffer member 5 provided with the some opening part 54 (refer FIG. 32). Moreover, you may use a different kind of buffer member 5 in the both edges of the solar cell module 100 (refer FIG. 33).

Thus, a desired number of solar cell modules can be stacked and held in the vertical direction in a horizontal state by the buffer member.

Next, as shown in FIG. 34, on the upper surface of the uppermost solar cell module 100, a top plate 6 made of, for example, cardboard is formed as a buffer so as to have a width wider than the width of the solar cell module 100.

The top plate 6 is bent along a straight line L that connects the outer wall surfaces of the support structure 2 stacked in the vertical direction and disposed at the corner portions 100a on both sides of the edge portion 100b along the longitudinal direction of the solar cell module 100. A bent portion 61 is provided. In a state where the top plate 6 is arranged on the upper surface of the uppermost solar cell module 100, straight lines connecting the outer wall surfaces of the support structure 2 with the bent portions 61 on both sides in the longitudinal direction of the top plate 6 as shown in FIG. Bend down along L.

(Description of other configuration examples of the top plate 6)
FIG. 36 shows another configuration example of the top plate 6.

The top plate 6 is a straight line that connects the outer wall surfaces of the support structure 2 (that is, the outer wall surfaces of the base member 23) disposed at the corner portions 100 a on both sides of the edge portion 100 b along the longitudinal direction of the solar cell module 100. A bent portion 61 that is bent along L is provided, and a pair of cuts 62 are formed in the bent portion 61 with a width interval facing the buffer member 5.

The bent portion 61 of the top plate 6 in which the notches are formed in this way is bent downward along a straight line L connecting the outer wall surfaces of the support structure 2 as shown in FIG.

At this time, as shown in FIG. 37, the bent portion 61 a between the notches 62 can be bent downward along the outer edge portion 100 b of the buffer member 5, and the bent portions 61 on both sides of the bent portion 61 of the support structure 2. It can be bent along a straight line L connecting the outer wall surfaces. That is, even when the outer edge portion 100b of the buffer member 5 protrudes outward from the straight line L connecting the outer wall surfaces of the support structure 2, the straight line L connecting the outer wall surfaces of the support structure 2 and the buffer member The

bent portions

61a and 61b of the top plate 6 can be individually brought into close contact with each other along the five edge portions 100b and bent.

As described above, the stacking packaging device according to the second embodiment is a stacking packaging device that stacks and packs solar cell modules in the vertical direction in a horizontal state, and is erected on the substrate unit and the upper surface of the substrate unit.

Further, the fitting convex portion 82 has a lower outer peripheral surface formed on a vertical surface 82b continuous with the inclined surface 82a. By forming the lower outer peripheral surface on the vertical surface 82b, it is possible to prevent the lateral displacement of the fitting recess 29 of the support structure 2 fitted to the fitting convex portion 82, that is, the lateral displacement of the support structure 2.

Moreover, a rib piece 83 is formed on the peripheral edge of the upper surface of the main body 81 so as to surround the fitting convex portion 82. In the present embodiment, the rib piece 83 excludes the corner portion of the support substrate 1 from the peripheral edge portion of the upper surface of the main body portion 81 (that is, is in contact with the auxiliary frame body 114 and the short side frame body 102). It is formed on the edge of the other two sides (excluding the edge that is present). When the rib piece 83 is placed with the fitting concave portion 29 of the support structure 2 fitted to the fitting convex portion 82, the rib piece 83 is placed on the outer peripheral portion of the support structure 2 (more specifically, the side surface of the support portion 28). Part).

By forming the rib pieces 83 in this way, it is possible to enhance the lateral displacement prevention effect of the support structure 2 fitted and arranged at the corner of the support substrate 1, particularly the displacement prevention effect in the center direction of the support substrate 1. . That is, the receiving member 8 of the present embodiment has a double slip prevention function by providing the fitting convex portion 82 and the rib piece 83.

Further, the height of the rib piece 83 is slightly lower than the height of the fitting convex portion 82. For example, the height of the fitting convex portion 82 is 11 mm, and the height of the rib piece is 8 mm. As described above, the height of the rib piece 83 is slightly lower than the height of the fitting projection 82 because the lower surface of the support structure 2 is ribbed when the support structure 2 is installed on the support substrate 1. This is to avoid interference with the piece 83. That is, when the support structure 2 is horizontally lowered and installed on the support substrate 1, the lower surface of the support structure 2 and the rib piece 83 may interfere if the target position of the placement position is shifted from the corner position toward the center. There is sex. However, if the height of the rib piece 83 is set lower than the height of the fitting convex portion 82, the fitting concave portion of the support structure 2 is caused before the interference between the lower surface of the support structure 2 and the rib piece 83 occurs. Since the installation position is corrected by the fitting of 29 and the fitting convex portion 82, the structure does not cause interference.

Further, an engaging portion 86 is provided on the bottom surface 85 of the main body 81 so as to protrude toward the end of the long side frame 101. The engaging portion 86 includes a support rod 86a that extends horizontally from the lower end edge of one side surface 81a of the main body portion 81, and an engagement piece 86b that is bent downward from the distal end portion of the support rod 86a. Has been. When the receiving member 8 is placed on the end portion of the upper corrugated plate 111, the support rod 86 a formed to protrude from the bottom surface 85 of the main body portion 81 fits into the groove portion 111 a of the upper corrugated plate 111, and the tip portion The engaging piece 86b is provided so as to engage with an end edge portion (an end edge portion of the bottom surface) of the groove portion 111a of the upper corrugated plate 111. In this way, by engaging the engagement piece 86b with the end edge portion of the groove portion 111a of the upper corrugated plate 111, the receiving member 8 attached to the long side frame body 101 becomes the other side of the long side frame body 101. Can be prevented from shifting to the end side.

Further, the receiving member 8 is formed with a through hole 88 penetrating from the upper surface to the lower surface of the main body portion 81. The through hole 88 is formed with a large diameter on the upper side and a small diameter on the lower side, and a stepped portion 88a between the large diameter and the small diameter at the center of the hole receives the head of the screw member 90 inserted from the large diameter side. Has become a department.

That is, as shown in FIGS. 44 and 45, the receiving portion 8 is inserted into the through hole 88 that is a screw insertion hole from the large diameter side and screwed into the bottom surface of the groove portion 111 a of the corrugated plate 111. It is fixed to the upper corrugated plate 111.

The receiving member 8 having such a shape is formed by injection molding using a resin such as PP (polypropylene) or ABS (acrylonitrile / butadiene / styrene copolymer).

Note that the gap between the upper corrugated sheet 111 and the lower corrugated sheet 111 is a hole through which the binding band 7 described later passes, and a hole into which a fork of a forklift is inserted when loading into a transport container or the like.

The above is description of the support substrate 1 which is embodiment of this invention.

Next, a packing method for stacking and packing the solar cell modules 100 in multiple stages using the support substrate 1 having the above configuration will be described with reference to FIGS. 49 to 57. The following packing method is performed by, for example, an automatic machine.

First, as shown in FIG. 49, the fitting protrusions 82 of the receiving member 8 arranged at the four corners of the support substrate 1 are respectively formed on the lower surface of the support portion 28 of the support structure 2 that is the first step. The fitted recesses 29 are fitted, and the first-stage support structure 2 is arranged at the four corners of the support substrate 1. Next, as shown in FIG. 50, the four corner portions 100 a of the first-stage solar cell module 100 are placed on the first-stage support structures 2. Next, as shown in FIG. 51, the engagement concave portions 26 of the second-stage support structure 2 are fitted and engaged with the engagement convex portions 25 of the first-stage support structure 2. Next, as shown in FIG. 52, the corners 100a at the four corners of the second-stage solar cell module 100 are placed on the second-stage support structures 2. Thereafter, by repeating the procedure shown in FIGS. 51 and 52 a predetermined number of times, as shown in FIG. 38, a predetermined number of solar cell modules 100 are stacked in multiple stages on the support substrate 1.

In the embodiment, the corner portion 100a of the solar cell module 100 includes the upper surface of the support portion 28 of the support structure 2 that supports the corner portion 100a of the solar cell module 100 and the support structure disposed on the upper surface thereof. It is configured to be sandwiched between the lower surfaces of the two support portions 28. Thereby, it is possible to prevent the individual solar cell modules 100 from flapping up and down (vertical direction Z).

Thereafter, as shown in FIG. 53, the solar cell module 100 is prevented from bending up and down at the center of both edge portions 100b along the longitudinal direction of the stacked solar cell modules 100, and is also caused by vibration during transportation. A shock-absorbing member 5 for preventing vertical flapping is fitted and arranged.

As the buffer member 5, for example, the buffer member 5 as shown in FIG. 11 can be used. As shown in FIG. 54, the upper and lower buffer members 5 are fitted into the end portions 100 b of the solar cell modules 100. Are arranged without gaps.

Therefore, as shown in FIG. 55, first, in this state, the solar cell module of the uppermost stage is passed from the support substrate 1 (more specifically, the upper corrugated sheet 111) so as to pass through the groove 53 of the buffer member 5. Up to 100 are wound around the binding band 7 and bound together.

Next, as shown in FIG. 56, on the upper surface of the uppermost solar cell module 100, a top plate 6 made of, for example, corrugated cardboard, having a width wider than the width of the solar cell module 100 is disposed as a buffer.

The top plate 6 has bent portions 61 that bend along a straight line L that connects the outer wall surfaces of the support structure 2 disposed at the four corners of the support substrate 1.

Then, as shown in FIG. 57, the bent portions 61 on both sides in the longitudinal direction of the top plate 6 are bent downward along the straight line L.

In this state, the binding band 7 is routed from the support substrate 1 (more specifically, the upper corrugated plate 111) to the top plate 6 at two places about 1/3 from both ends in the longitudinal direction. In this way, they are united together.

As described above, the support substrate according to the third embodiment is a support substrate that supports the solar cell module in a horizontal state by placing the support structure that supports the corners of the solar cell module. The upper surface of the substrate is formed with a fitting convex portion into which a fitting concave portion formed on the lower surface of the support structure is fitted.

Can be prevented. That is, it is possible to prevent the lateral displacement of the solar cell module with respect to the support substrate.

Further, according to the support substrate, the fitting convex portion may have a configuration in which the upper outer peripheral surface is formed on an inclined surface that gradually expands from the upper side toward the upper surface side of the support substrate. According to this configuration, by forming the upper outer peripheral surface as an inclined surface, the fitting recess formed on the lower surface of the support structure can be easily fitted, and workability is improved.

Further, according to the support substrate, the fitting convex portion may have a configuration in which a lower outer peripheral surface is formed on a vertical surface continuous from an inclined surface. According to this configuration, by forming the outer peripheral surface of the lower portion as a vertical surface, it is possible to prevent the lateral displacement of the fitting concave portion of the support structure fitted to the fitting convex portion, that is, the lateral displacement of the support structure.

Moreover, according to the said support substrate, it is good also as a structure which the rib piece which contact | abuts to the outer peripheral part of a support structure and prevents a shift | offset | difference to a horizontal direction was formed around the fitting convex part of the upper surface of a support substrate. . According to this configuration, it is possible to further enhance the effect of preventing the lateral displacement of the support substrate fitted and arranged at the corner of the support substrate.

Moreover, according to the said support substrate, the outer peripheral part of the support structure is formed in the planar view square shape, and a rib piece opposes two sides of the corner | angular part of a support substrate among the circumference | surroundings of a fitting convex part. It is good also as a structure formed except a part. As described above, the rib piece is formed by excluding the portion facing the two sides of the corner portion of the support substrate in the periphery of the fitting convex portion, and thus the support structure fitted and arranged at the corner portion of the support substrate. The effect of preventing the lateral displacement of the body, particularly the effect of preventing the displacement toward the center of the support substrate can be enhanced.

Further, according to the support substrate, the support substrate has a rectangular frame structure, the two long side frames facing the edge of the long side of the solar cell module, and the short of the solar cell module. It is good also as a structure provided with two short side frame bodies which oppose the edge part of a side side, and the receiving member in which the fitting convex part was formed in the both ends of the long side frame body.

According to this configuration, the support substrate can be reduced in weight by using a frame structure. Moreover, the mounting position of the receiving member can be adjusted in advance by configuring the receiving member as a member separate from the long side frame.

Further, according to the support substrate, the receiving member may include a main body portion formed in a square shape in plan view, and the fitting convex portion may be formed at the center of the upper surface of the main body portion.

Further, according to the support substrate, the rib piece may be formed on the peripheral edge of the upper surface of the main body. Further, the main body portion may include an engaging portion that protrudes toward the end of the long side frame, and the engaging portion may be engaged with the end of the long side frame.

According to the above configuration, since the lowermost support structure can be fitted and fixed to the engagement convex portion of the support substrate, the solar cell module can be stably packed in multiple stages without lateral displacement.

In addition, according to the above-described stacking and packing tool, it is possible to use the lowermost support structure placed on the substrate portion as the spacer member, that is, to also serve as the spacer member. By using the support structure as the spacer member, it is not necessary to prepare the spacer member separately, so that the number of members as a stacked packing tool can be reduced. In this case, the solar cell module is not placed on the lowermost support structure, and is only used as a spacer member.
