DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1 FIG.
The present embodiment shown in FIGS. 1 to 7 relates to a packaging device for overlapping and packaging a rectangular board 1 such as a solar battery panel. First, an outline of a solar cell panel as the rectangular board 1 will be described with reference to FIGS. 1 and 2. In the solar battery panel, a large number of solar battery cells are embedded, and an aluminum edge frame 3 is mounted on the four circumferences of a base whose surface is covered with a surface protective material 2 such as tempered glass. An inward flange 4 is provided on the back surface of the edge frame 3 to be attached to a frame or the like.
[0017]
The packaging device for stacking and packaging the rectangular board-shaped objects 1 having such a structure is made of a rigid paper material such as corrugated paper covering the two opposite side edges in the longitudinal direction of the rectangular board-shaped object 1 together with the corner portions. A pair of side buffering means 5 configured in a shape is provided with a partition structure 6 that holds the interval between the rectangular board-like objects 1 (see FIG. 4). A packaging form is adopted in which the rectangular plate-like object 1 in which the side edges are held by the two side buffering means 5 in a superposed state with a gap by the partition structure 6 is bound together with the binding band 7 together with the side buffering means 5. The two rectangular board-like objects 1 are stacked in a back-to-back state with the high-strength surface protective material 2 side facing outward.
[0018]
The side buffering means 5 and the partition structure 6 of the packaging device are configured by a bending operation of a single sheet of rigid paper material in a developed shape as shown in FIG. The sheet 8 has a shape in which one flap 9 is provided at each of the four corners of the short side of the rectangular flat plate portion. The flat plate portion is divided into six sections along the long side, and is vertically symmetrical at a cutting line 11 having connecting portions 10 at two locations near both ends provided on the center line. The outermost part along the long side is applied to the side edge in the longitudinal direction of the rectangular board 1 as an edge contact surface 12. A rising surface 14 is defined on the inner side of each edge contact surface 12 with the bend ruled line 13 as a boundary, which is in contact with the longitudinal side surface of the rectangular board 1, and another edge is formed on the inner side with the bend ruled line 13 as a boundary. A per-part surface 12 is defined. The flap 9 is formed to extend at both ends of the outer edge contact surface 12, and the edge contact surface 12 is partitioned by a bent ruled line 13.
[0019]
An inward insertion piece 15 is formed by an incision line 16 at the center of the bending ruled line 13 of the inner edge contact surface 12 on one inner side, and at the center of the bending ruled line 13 of the other inner edge contact surface 12. A slit-like hole 17 into which the insertion piece 15 can be inserted is formed, and an insertion structure is provided. The height dimension of the insertion piece 15 is substantially equal to the width dimension of the rising surface 14. Two rows of cuts are provided on both ends of the cutting line 11 on the center line so as to cross the cutting line 11 at right angles. The inner cut is straight, while the outer cut is convex. By this two cuts, a set of two hook structures 18 is formed on both ends of the cutting line 11 (see FIG. 4).
[0020]
The packaging operation by this packaging apparatus is performed by the following method. That is, two unfolded sheets 8 are laid out at an approximately width interval of the rectangular plate-like object 1 so that the front side edges in the longitudinal direction are placed on the adjacent edge contact surfaces 12 of the two sheets 8. The rectangular board 1 is placed on Thereafter, the rising surface 14 is raised by bending the bent ruled line 13 and is brought into contact with the side surface of the rectangular board 1 to reversely fold the connecting portion 10 on the cutting line 11 to contact the edges of the two inner surfaces. 12 are overlapped, and the partition structure 6 is assembled.
[0021]
Since the partition structure 6 is opened only by the bending cage and it is difficult to perform the next operation, the hooking structure 18 is bent as shown in FIG. 4, and the collar portion is hooked on the flange 4 on the back surface of the rectangular board 1. deep. As a result, the partition structure 6 is held in a stable assembly form, and is further abutted against the side edge on the back surface side of the rectangular board 1 in a form that is secured by inserting the insertion piece 15 into the hole 17 (FIG. 5). reference). This operation is performed on the two sheets 8 simultaneously or concurrently. The upper surface of the partition structure 6 is an edge contact surface 12 with respect to the upper rectangular disk-shaped object 1, and the upper rectangular disk-shaped object 1 is placed in the same manner as the lower rectangular disk-shaped object 1. Then, the rising surface 14 is raised by bending the bent ruled line 13 and is brought into contact with the side surface of the upper rectangular board 1, and the edge contact surface 12 is bent by the bent ruled line 13, so that the upper side surface side edge is formed. I guess.
[0022]
Thereafter, the flap 9 is bent along the lateral side and fixed with a tape or the like. As a result, the corners of the four corners that are most susceptible to scratching are securely protected by double flaps 9 from both sides. Finally, the two to three portions across the two side buffering means 5 are banded by the binding band 7 and the whole is bound to complete the packaging by the packaging device (see FIG. 6). For unpacking, it is sufficient to follow the reverse procedure described above, and the flat sheet 8 can be easily formed and easily recycled.
[0023]
This packaging device mainly protects only the parts that are easily damaged, and omits the packaging of the parts that do not cause a problem. The solar cell panel is installed outdoors, and the surface protection material 2 has a high strength design, and there is almost no need to cover the whole. Therefore, the packaging of this part is omitted, and no partition is provided on the entire surface, so that the rectangular board-like objects 1 are not brought into contact with each other by the double-structured partition structure 6 having a buffer function. The packaging work is completed in parallel with the assembly of the packaging device, so that the work efficiency is high, which can contribute to a significant reduction in packaging costs as well as a reduction in materials.
[0024]
The insertion piece 15 is interposed in the longitudinal direction at the intermediate portion of the side buffering means 5 and fulfills a supporting function, so that the assembled shape is stabilized and also a buffering function. Although the cutting line 11 on the center line can be constituted by a bent ruled line, it becomes a reverse-folded ruled line, so two steps are required, and the cost becomes high.
[0025]
In addition, by adopting a configuration in which flaps are extended at both ends of the rising surface 14 and bent into the rising surface 14, both sides of the corner portion can be protected by a double structure. Moreover, you may make it cut | disconnect by the cutting line 11 of a centerline, and what was divided | segmented into 2 sheets may be combined with an adhesive agent etc. Furthermore, when it is necessary to protect also the short side direction of the square board-shaped object 1, the unfolded-shaped sheet | seat 19 as shown in FIG. When there are three rectangular discs 1 to be packaged, three sets of each surface configuration of the sheet 8 are formed.
