Embodiments for Carrying Out the Invention

[0015] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following, the same elements in all the drawings are denoted by the same reference numerals, and duplicate explanations are omitted. Also, in the description in the text, the reference numerals described previously will be used as necessary. FIG. 1 shows a perspective view from the front side and FIG. 2 shows a perspective view from the back side (closed state) of the columnar core dedicated storage box 1 of the present invention in a closed state.

[0016] One embodiment of the columnar core dedicated storage box 1, as shown in Figures 1 and 2, consists of a set of cushioning material 2 (not shown in Figures 1 and 2) and a set of rectangular parallelepiped boxes 3 (3A, 3B) for housing the cushioning material 2. On the front side of the columnar core dedicated storage box 1, that is, the side on which the opening and closing operations of each box 3A, 3B are performed, fasteners K (K1, K2) are provided as shown in Figure 1, and on the back side, as shown in Figure 2, a pair of removable hinges 4 (4A, 4B) are provided on the edges of each box 3A, 3B.

[0017] Figure 3 shows a perspective view of the columnar core storage box 1 from the front when it is open, and Figure 4 shows a perspective view of the columnar core storage box 1 in a separated state. By releasing (unlocking) the fasteners K1 and K2 on the front side of the columnar core storage box 1, the box bodies 3A and 3B can be opened around the removable hinges 4A and 4B as shown in Figure 3, and a set of cushioning materials 2A and 2B placed inside each box body 3A and 3B can be seen.

[0018] Furthermore, as shown in Figure 4, the columnar core dedicated storage box 1 can be separated into individual box bodies 3A and 3B by separating a pair of removable hinges 4A and 4B from each other. The details of the box bodies 3 (3A, 3B) and cushioning material 2 (2A, 2B) that form the columnar core dedicated storage box 1 of the present invention will be described below with reference to the drawings.

[0019] <Box 3 (3A, 3B)> Figure 5 shows perspective views of the box bodies 3A and 3B that form the columnar core dedicated housing box 1 of the present invention. As shown in Figure 5, the box bodies 3A and 3B are composed of a rectangular parallelepiped shape with one side open, and a pair of box bodies 3A and 3B are the same shape. That is, as shown in Figure 5, the width (longitudinal direction), depth (short direction), and thickness of a pair of box bodies 3A and 3B are the same. In addition, a space is provided inside the box bodies 3A and 3B for housing the cushioning material described later. The box bodies 3 (3A, 3B) are made of lightweight and durable materials to facilitate installation and movement. In particular, emphasis is placed on the function of safely protecting the columnar core by being resistant to shocks and vibrations during transportation. Furthermore, the internal structure of the box bodies 3 (3A, 3B) can be freely customized according to the size and material of the cushioning material described later, and can accommodate columnar cores of various sizes and shapes.

[0020] Furthermore, frame members are formed upright on all four sides around the space that houses the cushioning material, and fasteners K1 and K2 for opening and closing the box bodies 3A and 3B are provided on the edges of the frame members on the longer sides, as shown in Figure 5. In addition, removable hinges 4A and 4B are attached at positions opposite to the fasteners K1 and K2 (on the edges of the frame members on the other longer side), as shown in Figure 5. By fitting these pair of removable hinges 4A and 4B together, a pair of box bodies 3A and 3B are joined together, making it possible to open and close the columnar core dedicated storage box 1.

[0021] In particular, the removable hinges 4A and 4B are designed to be highly resistant to wear, even in environments where frequent opening and closing occurs, and are made of durable materials such as stainless steel. This allows for stable use over a long period of time and significantly reduces the frequency of maintenance. Furthermore, to release moisture (water droplets) generated from the columnar core to the outside of the dedicated storage box 1 for the columnar core, air holes 31-36 can be provided that penetrate the inside and outside of the box bodies 3A and 3B, as shown in Figures 1, 2, and 5. This prevents the accumulation of moisture even during long-term storage of the columnar core, minimizing deterioration of the columnar core. This design is particularly intended for use in humid environments and is a highly reliable structure.

[0022] <Buffer material 2 (2A, 2B)> Figure 6 shows a perspective view of the cushioning material 2A that forms part of the columnar core dedicated housing box 1 of the present invention, Figure 7 shows a plan view of the same cushioning material 2A, Figure 8 shows a cross-sectional view of the cushioning material 2A shown in Figure 7 along line XX, and Figure 9 shows a partially enlarged view of the groove portion 22A of the cushioning material 2A shown in Figure 8. As shown in Figures 6 and 7, the cushioning material 2 (2A, 2B) has a rectangular parallelepiped base portion 21, and three groove portions 22 (22A, 22B, 22C) are formed on one surface 21F. These groove portions 22 are arranged along the longitudinal direction ND of the base portion 21 and can be customized according to the shape and dimensions of the columnar core, and can accommodate columnar cores of various sizes. In addition, the groove portions 22 (22A, 22B, 22C) are smoothly molded and designed to prevent damage to the columnar core.

[0023] As shown in Figure 8, the cross-section of the groove portion 22 (22A, 22B, 22C) is semicircular, and the cylindrical columnar core is designed to fit into this semicircular groove portion 22 (22A, 22B, 22C). Furthermore, as shown in Figures 6 and 7, steps d1 to d6 are formed along the longitudinal direction ND of the groove portion 22 (22A, 22B, 22C) at the boundary between the groove portion 22 (22A, 22B, 22C) and one surface 21F of the base portion 21.

[0024] Furthermore, in order to release moisture (water droplets) generated from the columnar core to the outside of the dedicated storage box 1 for the columnar core, grooves 22 (22A, 22B, 22C) and air holes 23-25 ​​that penetrate the back of the base 21 can be provided as shown in Figure 7. This allows moisture accumulated in the columnar core to be efficiently discharged to the outside, suppressing internal humidity. This structure plays a very important role in maintaining the quality of the columnar core.

[0025] For example, on both sides of the groove 22A (the short-side MD side of the base 21), two steps d1 and d2 are formed along the longitudinal direction ND of the groove 22A, as shown in Figures 6 and 8. When a cylindrical columnar core W is housed in the groove 22A, consider the case where observation and photography are performed using two imaging devices C1 and C2 from two locations diagonally above the columnar core W, as shown in Figure 9. Since the cushioning material that forms part of the columnar core dedicated housing box of the present invention is provided with steps d1 and d2 in the groove 22A, as shown in Figures 6 to 9, visual observation and photography with imaging devices C1 and C2 can be performed up to the side surface (side circumferential surface) of the columnar core W located below one surface 21F of the base 21, as shown in Figure 9.

[0026] In other words, when imaging a columnar core W housed in a groove 22A of cushioning material forming part of a dedicated storage box for columnar cores using two imaging devices C1 and C2, the imaging ranges E1 and E2 of the columnar core W from the two imaging devices C1 and C2 overlap, resulting in an imaging range θ that exceeds 180°, starting from the center O of the columnar core W. This entire imaging range E1 and E2, which exceeds 180°, allows for detailed capture of the overall shape and appearance of the columnar core W, making it extremely effective in quality control and inspection processes.

[0027] In the embodiment of the cushioning material 2A shown in Figures 6 to 9, steps d1 to d6 are provided at the boundary between the groove portion 22 (22A, 22B, 22C) and one surface 21F of the base portion 21. However, even if chamfering such as R chamfering or C chamfering is applied to this boundary portion along the longitudinal direction ND of the cushioning material 2, it is still possible to observe and photograph the side surface (side circumferential surface) of the columnar core W located below one surface 21F of the base portion 21 shown in Figure 9. Furthermore, in this embodiment, the cross-sectional shape of the groove portion 22 (22A, 22B, 22C) is semicircular as shown in Figures 8 and 9, but it may also be rectangular, such as a square.

[0028] Next, the method for observing (photographing) the columnar cores housed and stored in the aforementioned dedicated storage box will be explained using diagrams. Figures 10 to 16 show the state of the dedicated storage box for columnar cores during observation (photography) of the columnar cores. In this embodiment, in order to photograph the entire side surface of the columnar core, it is necessary to first open one side of the dedicated storage box and take a photograph, then flip the dedicated storage box over, open the other side, and take another photograph. This observation (photography) method makes it possible to accurately observe and photograph the entire circumference of the side surface of the columnar core without damaging it. The specific procedure will be explained in detail below.

[0029] <Step 1: Installation of dedicated storage boxes for columnar cores and placement of imaging equipment> First, the columnar core is placed in the grooves 22 (22D~22F) of the cushioning material 2B of the columnar core dedicated storage box 1. As mentioned above, the grooves 22 are provided with steps d (d1~d6) as shown in Figures 7 and 8, which stably fix the columnar core in place and hold it in place so that it does not move during shooting. In addition, the columnar core dedicated storage box 1 not only protects the columnar core but also has the function of providing a stable shooting environment.

[0030] Before shooting, it is important to set up the dedicated storage box 1 for the columnar core on a flat surface and adjust the pair of boxes 3A and 3B so that they do not shake. Cameras, video cameras, and other imaging equipment (not shown) should be positioned at an appropriate distance on one side so that half of the columnar core is within the shooting range. At this time, it is important to adjust the focus and angle of the imaging equipment, and it is desirable to shoot from multiple angles in order to obtain accurate images of the surface of the columnar core. In addition, regarding the lighting of the shooting environment, it is important to ensure that the light source is uniform and to position it in a way that minimizes shadows and reflections, which will lead to the acquisition of high-quality images.

[0031] <Step 2: Open one side of the box and observe / photograph> Next, as shown in Figure 10, carefully open one side of the dedicated storage box 1 for the columnar cores, box body 3A. At this time, it is preferable to open and close the box slowly so as not to suddenly open and shock the columnar cores W11~W13. By opening box body 3A, half of the columnar cores W11~W13 are exposed, thereby allowing a part of the columnar cores W11~W13 to be directly inspected. Separate box bodies 3A and 3B with the removable hinges 4A and 4B as shown in Figure 11, leaving only box body 3B, which is the subject of the photograph, as shown in Figure 12.

[0032] In box 3B, confirm that the exposed columnar cores W11-W13 are securely fixed to the cushioning material 2B, and then photograph half of the surface using imaging equipment (not shown). For example, by using multiple cameras or other imaging equipment as shown in Figure 9, the entire area of ​​the exposed columnar core can be photographed, and images can be recorded without any omissions. During shooting, particular attention should be paid to ensuring that the settings and focus of the imaging equipment are accurately adjusted. Furthermore, the position of the imaging equipment should be appropriately adjusted according to the area to be observed, and it is recommended that the images be reviewed after shooting.

[0033] <Step 3: Close the dedicated storage box for the columnar core and turn it upside down.> Once the shooting is complete, connect box 3A to box 3B with the interlocking hinge as shown in Figure 13, then close the opened box 3A again as shown in Figure 14, and secure it firmly with fasteners K1 and K2. After confirming that boxes 3A and 3B are completely closed, carefully lift the columnar core storage box 1 as shown in Figure 15 and turn it inside out. At this time, care must be taken with how you lift it and the speed of the work to prevent the columnar core from moving inside.

[0034] In particular, when handling large columnar cores, having two or more workers cooperate to operate the box ensures safe and efficient work. When turning over the dedicated storage box for columnar cores, it is important to always be aware of the changes in gravity acting on the columnar cores W11-W13 and the state of the columnar cores W11-W13 within the dedicated storage box 1. In addition, during this process, it is necessary to reconfirm the state of the cushioning material placed around the columnar cores W11-W13 and check whether the cushioning material is held in the correct position.

[0035] <Step 4: Open the box on the opposite side and observe / photograph> After turning over the dedicated storage box 1 for the columnar cores, open the box 3B on the opposite side as shown in Figure 16. Now, confirm that the columnar cores W11~W13 are securely fixed by the grooves 22A~22C of the cushioning material 2A. Once this confirmation is complete, separate the pair of boxes 3A and 3B from each other as shown in Figures 11 and 12, and with only box 3A containing the columnar cores W11~W13 remaining, take another photograph of the columnar cores W11~W13 from the opposite side using photographic equipment (not shown).

[0036] Readjust the position and angle of the imaging equipment to ensure that the imaging range of columnar cores W11-W13 is completely covered. If necessary, change the focus and exposure settings of the imaging equipment to avoid light reflections. Imaging from the opposite side allows for detailed observation of areas that could not be captured previously. In particular, by carefully arranging the light source and imaging equipment, uniform observation of the entire columnar core becomes possible, and the outer surface of the columnar core can be recorded without any omissions.

[0037] In this step, images taken from both side surfaces are compared to confirm the overall appearance and surface condition of the columnar core. When integrating the captured data, it is important to identify overlapping sections and format the data into an easily analyzable format. This ensures a complete record of the columnar core, providing valuable data for future quality control and inspection.

[0038] <Step 5: Closing the dedicated storage box for columnar cores and restoring the original condition> Once the photography is complete, close the box 3B and re-close the fasteners K1 and K2. This completely closes the dedicated storage box 1 for the columnar cores, protecting the columnar cores W11 to W13. Return the dedicated storage box 1 for the columnar cores to its original position, completing the 360-degree photography of the side surfaces of the columnar cores W11 to W13.
