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

  FIG. 9 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. 9, the outline of the loading packaging tool A before final packing is demonstrated.

  The stacking packing tool A shown in FIG. 9 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 support member 2 that supports each of corner portions 100a (hereinafter also referred to as corner portions) of solar cell modules 100 that are installed and horizontally stacked, and a pair of opposing edges of solar cell modules 100 that are stacked horizontally The buffer member 5 that holds the solar cell module 100 by being fitted to the part 100b from the lateral direction is provided.

  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 member 2 is configured to stack and package the solar cell modules 100 in a horizontal state. Four support members 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 members 2 are positioned by being fitted to fitting protrusions 1 a on the pallet 1. The four support members 2 support the four corners 100a (corner portions) of the rectangular solar cell module 100, respectively.

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

  The solar cell module 100 supported by the support member 2 is frameless. That is, the frameless solar cell modules 100 can be stacked and packed by the support member 2 in multiple stages.

  FIG. 1A is a perspective view of the support member 2 as viewed obliquely from above, and FIG. 1B is a perspective view of the support member 2 as viewed from obliquely below.

  The support member 2 has a structure for receiving the corner portion 100a of the solar cell module 100 from below, and a base portion 23 bent in an L shape in plan view, and a lower end portion of the inner wall surface of the base portion 23 on the wall surface. And a quadrangular receiving portion 28 (supporting portion) extending in a direction orthogonal to each other.

  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 member 2 is formed in a substantially L-shaped longitudinal section.

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

  In this way, when the support member 2 is placed on the pallet 1 by forming the fitting convex portion 1 a on the upper surface of the pallet 1 and forming the fitting concave portion 29 on the lower surface of the receiving portion 28 of the support member 2. The lateral displacement of the support member 2 can be prevented by this fitting structure.

  The base portion 23 is configured to be stacked in the vertical direction Z. Therefore, an engaging convex portion 25 and an engaging concave portion for sequentially fitting and engaging with the base portion 23 of another support member 2 arranged adjacent to each other on the upper and lower surfaces 23a and 23b of the base portion 23. 26 are 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.

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

  FIG. 2 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 formed of, for example, foamed plastic or foamed urethane.

  FIG. 3 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. 4 is a perspective view of still another buffer member 5 as viewed obliquely from above.

  In the buffer member 5, a tapered surface that guides the edge 100 b of the solar cell module 100 is formed at the opening tip 57 of the opening 54 (opening groove) of the buffer member 5 shown in FIG. 2. 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. 5, the fitting concave portions 29 formed on the lower surface of the receiving portion 28 of the support member 2 which is the first stage are respectively formed on the four fitting convex portions 1 a of the substrate portion 1. The first-stage support member 2 is arranged by fitting into the fitting convex portion 1a formed on the upper surface.

  Next, as shown in FIG. 6, the four corner portions 100 a of the first-stage solar cell module 100 are placed on the first-stage support members 2. Next, as shown in FIG. 7, the engaging recesses 26 of the second-stage support member 2 are fitted and engaged with the engagement protrusions 25 of the first-stage support members 2. Next, as shown in FIG. 8, the corners 100 a at the four corners of the second-stage solar cell module 100 are placed on the second-stage support members 2. Thereafter, by repeating the procedure shown in FIGS. 7 and 8 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. 9).

  10 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.

  In this manner, 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 the 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 abuts the upper surface of the pallet 1.

  For example, 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 member 2 (see FIG. 11) will be described. Here, the spacer member 3 has a cubic shape as shown in FIGS. 12A and 12B, and the lower surface placed on the pallet 1 has fitting protrusions 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 member 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 members 2 are stacked on the spacer members 3 at the four corners, and the solar cell module 100 is supported by the support members 2 at the four corners. The corner portions 100a are placed so as to be placed, and thereafter, the stacking of the support members 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 stacked on the pallet 1 in multiple stages. 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. 13 shows a cross-sectional view of the solar cell module 100, the support member 2, and the spacer member 3.

  Accordingly, as shown in FIG. 14, 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. 14 is a cross-sectional view of the solar cell module 100 and the buffer member 5.

  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 member 2. Designed. That is, the height T11 (see FIG. 14) from the upper surface of the uppermost solar cell module to the upper surface 53 of the uppermost buffer member 5 is from the upper surface of the uppermost solar cell module to the upper surface of the uppermost support member 2 (see FIG. 14). That is, since it is equal to the height T11 up to the height of the engaging projection 25 (see FIG. 13), the shape of the uppermost buffer member 5b is different from the shapes of the other buffer members 5.

  In addition, the shape of the uppermost buffer member 5b and the shape of the other buffer members 5 may be the same shape. In this case, the engagement convex portion of the support member 2 from the upper surface of the solar cell module 100 of each step. The height T11 up to 25 (see FIG. 13) is equal to the height S (see FIG. 14) of the upper surface of the buffer member 5 from the upper surface of the solar cell module 100 at each stage.

  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 member 2, so that the upper surface of the buffer member 5b and the support member 2 Even when a later-described top plate 6 is placed on the upper surface, 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 stacking the buffer member 5 having one opening 54 (opening groove) in the vertical direction (see FIG. 14) or by stacking the buffer member 5 provided with a plurality of openings 54. It does not matter (see FIG. 15). 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. 16). Moreover, you may use a different kind of buffer member 5 in the both edges of the solar cell module 100 (refer FIG. 17).

  Accordingly, 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. 18, a top plate 6 made of, for example, corrugated 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 is bent so as to be bent along a straight line L that connects the outer wall surfaces of the support members 2 stacked in the vertical direction, which are arranged at the corner portions 100a on both sides of the edge portion 100b along the longitudinal direction of the solar cell module 100. A 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, a straight line L connecting the outer wall surfaces of the support member 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 the line.

  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.

  Thereafter, although not shown, 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.

(Description of other configuration examples of the top plate 6)
FIG. 20 shows another configuration example of the top plate 6.

  The top plate 6 is a straight line L that connects the outer wall surfaces of the support member 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 pair of cuts 62 are formed in the bent portion 61 with a width interval facing the buffer member 5.

  As shown in FIG. 21, 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 that connects the outer wall surfaces of the support member 2.

  At this time, as shown in FIG. 21, 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 are outside the support member 2. It can be bent along a straight line L connecting the 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 member 2, the straight line L connecting the outer wall surfaces of the support member 2 and the buffer member 5 The bent portions 61a and 61b of the top plate 6 can be individually brought into close contact with each other along the edge portion 100b and bent.

  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.
