The shape is such that it is continuous (substantially petal shape), and the projecting shape portion 56 has a first projecting shape portion 56a and a second projecting length shorter than that of the first projecting shape portion 56a on the outer peripheral side. The protruding portions 56b are arranged alternately. In the present embodiment, the diameter of the virtual circle passing through the tip portions of the four first projecting shape portions 56a in the protruding direction and the inner diameter of the shaft portion 8 are configured to be the same.

As described in detail above, according to the present embodiment, the lid member 4 includes a handle portion 34 within a range in which a part of the hand is placed on the upper surface of the lid member 4 and a finger can be hung. By providing the handle portion 34 on the upper portion of the lid member 4 in this way, when attaching or detaching the lid member 4 to or from the container body 2, the user does not reach to the lower portion of the lid member 4 and put his or her hand on it. It is possible to improve workability. In particular, when the vertical width (height) of the lid member 4 is relatively long, such as when the lid member 4 accommodates about the upper half of the roll-shaped article 7, the workability of attaching and detaching the lid member 4 is improved. The effect of trying is more remarkable. In the present embodiment, when the lid member 4 is removed, when the hand is placed on the upper part of the lid member 4, the hips are bent or the knees are bent, etc., as compared with the case where the hand is placed on the lower part of the lid member 4. The change in the posture of the worker is alleviated. Therefore, the lid member 4 can be attached and detached relatively smoothly without difficulty.

Further, the lid member 4 is formed to be thinner than the container body 2. Therefore, the weight of the lid member 4 can be reduced, and as a result, the workability of attaching and detaching the lid member 4 can be improved.

In addition, the top plate portion 31 forming the upper surface of the lid member 4 is formed in an arch shape. Therefore, while reliably accommodating the roll-shaped article 7, for example, the weight of the lid member 4 can be reduced as compared with the case where the lid member 4 is formed in a square box shape. Further, it is possible to make it difficult to place another article on the lid member 4, and it is possible to prevent the lid member 4 from being deformed or damaged by placing another article on the lid member 4. As a result, it is not necessary to secure the strength assuming that another article is placed on the lid member 4, and the weight of the lid member 4 can be further reduced.

Further, the handle portion 34 is configured by projecting both ends of the top plate portion 31 upward. Therefore, the handle portion 34 can be formed with a relatively simple structure. Further, since the handle portions 34 are provided at both ends of the top plate portion 31, the fingertips of the hand holding the handle portion 34 can be released below the upper surface of the lid member 4, and the fingertips can be released to the side surface of the lid member 4. Can be pressed against. Therefore, the lid member 4 can be easily held while suppressing the upward protrusion length of the handle portion 34.

Further, in the present embodiment, since the container main body 2 is provided with the main body side flange portion 14, the shaft portion 8 of the roll-shaped article 7 is placed on the inner side of the roll storage container 1 with respect to the outer edge portion of the main body side flange portion 14. Can fit. Further, by covering the container body 2 containing the roll-shaped article 7 with the lid member 4, the opening of the bearing portion 15 to the outside of the container body 2 is covered by the covering portion 38. Therefore, it is possible to avoid a situation in which the inner space of the roll storage container 1 opens to the outside of the roll storage container 1 via the bearing portion 15. Therefore, by covering the container body 2 with the lid member 4, the gap of the roll storage container 1 in the peripheral portion of the bearing portion 15 (the end portion of the shaft portion 8) can be closed, and the gap of the roll storage container 1 can be closed through the peripheral portion of the bearing portion 15. It is possible to prevent foreign matter and the like from entering the inside of the roll storage container 1.

Further, the container body 2 includes a cap member 5 that protrudes upward from the bearing portion 15 and is supported by the bearing portion 15, and a stopper portion 16 that can regulate the displacement of the shaft portion 8 to the outside of the container body 2. ing. Therefore, when the roll-shaped article 7 is about to be displaced inside the roll storage container 1 when the roll storage container 1 is transported, the stopper portion 16 prevents the roll-shaped article 7 from being further displaced. Can be done. Therefore, it is possible to prevent the misaligned roll-shaped article 7 from directly colliding with the lid member 4 (covered portion 38). Thereby, the anxiety about the impact resistance of the lid member 4 can be dispelled. As a result, it is possible to reduce the weight of the lid member 4 and improve the workability of attaching and detaching the lid member 4 while suppressing the complicated shape and the increase in size of the lid member 4. Further, by restricting the misalignment of the roll-shaped article 7 at the stopper portion 16 and the portion corresponding to the shaft portion 8, the roll 9 of the roll-shaped article 7 itself is the container body 2 (long side side wall portion 12). It is possible to prevent a situation in which the product comes into contact with the inner surface and is damaged.

The stopper portion 16 is provided with a notch portion 17, and the end opening of the cap body 53 of the cap member 5 installed (supported) in the bearing portion 15 is opened through the notch portion 17 to form a container. It is designed to be exposed to the outside of the main body 2. Therefore, when the roll-shaped article 7 is taken in and out of the container body 2 using the robot arm, the robot arm is moved to the shaft portion 8 after the cap member 5 mounted on the shaft portion 8 is supported by the bearing portion 15. The robot arm can be inserted into the cap member 5 and the shaft portion 8 supported by the bearing portion 15 while the roll-shaped article 7 is installed in the container body 2.

Further, in the lid member 4 of the present embodiment, when the container main body 2 is covered, the main body side flange portion 14 and the folded-back portion 18 provided on the entire circumference of the upper side portion of the container main body 2 are outside the container main body 2. It includes an outer peripheral edge portion 37 that covers from the side. Further, the covering portion 38 is a part of the outer peripheral edge portion 37, and the general portion 39 which is another portion of the outer peripheral edge portion 37 is connected to the covering portion 38. With this configuration, by covering the container body 2 with the lid member 4, the entire circumference of the upper side portion of the container body 2 is covered by the lid member 4 from the outer peripheral side of the container body 2. Therefore, it is possible to more reliably prevent foreign matter and the like from entering the inside of the roll storage container 1.

In addition, the container body 2 is provided with a bearing reinforcing rib 22 connected to at least one of the bearing portion 15 and the stopper portion 16. Therefore, the rigidity and strength of the bearing portion 15 and the stopper portion 16 of the container body 2 can be increased, and the deformation and damage of the bearing portion 15 and the stopper portion 16 can be prevented. Further, main body flange reinforcing ribs 21 are provided at positions on both sides of the bearing reinforcing ribs 22, and in the present embodiment, the bearing reinforcing ribs 22 and the main body flange reinforcing ribs 21 are provided in the height direction of the container main body 2. It is provided not only in the upper range of the lower receiving portion 19 but also in the lower range of the lower receiving portion 19 (provided extending below the lower end portion of the bearing portion 15). As a result, the rigidity of the long side side wall portion 12 provided with the bearing portion 15 is increased, and the deformation of the long side side wall portion 12 can be suppressed. Therefore, for example, when the roll-shaped article 7 collides with the stopper portion 16, the long side side wall portion 12 of the container body 2 is deformed outward, and the distance between the pair of long side side wall portions 12 facing each other increases. This makes it possible to prevent the shaft portion 8 (cap member 5) of the roll-shaped article 7 from falling off from the bearing portion 15. As a result, the roll-shaped article 7 can be stored more stably.

Further, the lid member 4 is provided with a covering reinforcing rib 47 connected to at least one of the covering portion 38 and the closing portion 43. Therefore, the rigidity and strength of the covering portion 38 and the closing portion 43 of the lid member 4 can be increased, and deformation or damage of the covering portion 38 and the closing portion 43 can be prevented.

Further, in the present embodiment, resin cap members 5 are attached to both ends of the shaft portion 8 of the roll-shaped article 7, and the roll-shaped article 7 is supported by the container body 2 (bearing portion 15) via the cap member 5. Will be done. As a result, it is possible to reinforce the portion of the shaft portion 8 into which the insertion portion 52 of the cap member 5 is inserted, and it is possible to suppress deformation of the portion. Further, the cap member 5 (insertion portion 52) is a portion of the shaft portion 8 where the roll 9 is wound and deformation is suppressed (a portion closer to the center portion in the width direction of the roll than the side end surface of the roll 9). It has been inserted up to. Therefore, for example, when the cap member 5 is inserted only in a portion of the shaft portion 8 that protrudes outward from the side end surface of the roll 9, the roll-shaped article 7 to which the cap member 5 is attached is placed in the container body. When installed in 2, it is possible to prevent a situation in which a portion of the shaft portion 8 protruding outward from the side end surface of the roll 9 is curved or the like. Therefore, the roll-shaped article 7 can be stably supported (suspended in the air) by using the cap member 5, and as a result, the accommodation state of the roll-shaped article 7 can be stabilized.

In addition, the cap member 5 does not come into direct contact with the roll 9, but supports the roll 9 via the shaft portion 8, and the cap member 5 directly presses against the roll 9 to deform the roll 9. It is also possible to prevent such a situation.

Further, the support portion 51 of the cap member 5 has a two-layer structure including a cap main body 53 and an outer peripheral wall portion 54 provided so as to surround the outer periphery of the cap main body 53, and further, the outer peripheral wall portion 54 and the cap main body 53. Is connected by a support connecting rib 55. As a result, the strength and rigidity of the support portion 51 can be increased. Further, by providing the outer peripheral wall portion 54, for example, the area of the cap member 5 supported by the bearing portion 15 can be increased as compared with the case where the cap main body 53 is supported by the bearing portion 15. As a result, the roll-shaped article 7 can be supported more stably by using the cap member 5. In addition, by providing the outer peripheral wall portion 54 on the outer peripheral side of the cap main body 53, it is possible to prevent a situation in which the entire cap member 5 is inserted into the shaft portion 8.

Further, the boundary portion between the end surface of the cap member 5 on the support portion 51 side and the outer peripheral surface of the support portion 51 has a chamfered shape. Further, the upper edge portion of the stopper portion 16 of the container body 2 (the boundary portion between the stopper portion 16 and the bearing reinforcing rib 22 provided along the upper edge portion of the stopper portion 16) has a chamfered shape of the container body 2. It has become.

Therefore, when the roll-shaped article 7 to which the cap member 5 is attached is installed on the container body 2, the position of the roll-shaped article 7 with respect to the container body 2 is slightly displaced, so that the outer peripheral surface of the support portion 51 and the cap member Even if the boundary portion with the end surface of 5 abuts on the upper side portion of the stopper portion 16 of the container body 2, the chamfered shape of the boundary portion allows the cap member 5 to be smoothly guided to the bearing portion 15 side, which is relatively relatively. The cap member 5 can be smoothly installed on the bearing portion 15. Further, by omitting the corner portion which is relatively easily scraped or damaged at the boundary portion, the durability of the cap member 5 is prevented while preventing foreign matter formed by scraping from adhering to the roll 9. Can be improved.

Further, since the stopper portion 16 is provided, it is possible to prevent the cap member 5 from falling off from the bearing portion 15 to the outside. In particular, when the roll-shaped article 7 to which the cap member 5 is attached is installed on the container body 2 using the robot arm and then the robot arm is pulled out from the shaft portion 8, the robot arm is caught by the cap member 5 and the cap member It is possible to reliably avoid a situation in which 5 is dropped out. Further, for example, when taking out the roll-shaped article 7 installed in the container body 2, when inserting a relatively long robot arm from one end side to the other end side of the shaft portion, the other end It is possible to reliably avoid a situation in which the cap member 5 mounted on the portion side is pushed out by the robot arm and falls off.
