By the way, when a roll-shaped article is stored in a roll storage container in a suspended manner as described above, there is a concern that stress may be concentrated on the shaft portion. In particular, since the shaft of a roll-shaped article is basically a cylindrical body made of paper, if the roll is relatively heavy, the shaft deforms and the roll comes into contact with the inner surface or bottom of the roll storage container. There is a risk of damage etc.

The present invention has been made in order to solve the above-mentioned problems, and an object thereof is to provide a roll storage container that can stabilize the storage state of roll-shaped articles.

Below, each means suitable for solving the above objectives will be explained in terms of sections. Note that effects specific to the corresponding means will be added as necessary.

Means 1. A roll storage container capable of accommodating a roll-shaped article, which includes a substantially cylindrical shaft and a roll wound around the shaft,
A box-shaped container body having an opening that opens upward; a lid member that covers the container body and closes the opening; and a resin cap member that is attached to both ends of the shaft of the roll-shaped article. and
The container body is provided with a body side flange portion extending outward from the upper side of the container body,
The main body side flange portion is provided with a bearing portion that can support each of the cap members attached to both ends of the shaft portion,
The cap member includes a support part supported by the bearing part and an insertion part inserted into the shaft part,
The insertion portion is inserted into the shaft portion closer to the center portion in the width direction of the roll than the side end surface of the roll,
The cap member is
A substantially cylindrical cap body,
a substantially cylindrical outer peripheral wall portion provided to surround the outer periphery of the cap main body;
comprising a support connection rib that connects the outer peripheral wall portion and the cap main body,
The support connection rib is
a plurality of first support connection ribs provided radially at predetermined intervals in the circumferential direction of the cap body;
A roll storage container comprising: a second support connection rib that connects an edge of the outer peripheral wall on the insertion section side and the cap main body in an annular manner.

According to means 1, resin cap members are attached to both ends of the shaft portion, and the rolled article is supported by the container body (bearing portion) via the cap members. Thereby, it is possible to reinforce the portion of the shaft portion into which the insertion portion of the cap member is inserted, and it is possible to prevent deformation of the portion. Furthermore, the cap member (insertion part) is inserted to a part of the shaft part where the roll is wound and deformation can be said to be suppressed. For this reason, when a roll-shaped article with a cap member attached is installed in the container body, for example, when the cap member is inserted only into the part of the shaft that protrudes outward from the side end surface of the roll, It is possible to prevent a situation in which a portion of the shaft portion that protrudes outward from the side end surface of the roll is bent or the like. Therefore, the roll-shaped article can be stably supported (suspended in the air) using the cap member, and as a result, the accommodation state of the roll-shaped article can be stabilized.

In addition, the cap member does not directly contact the roll, but supports the roll via the shaft, which prevents the cap member from directly pressing against the roll and deforming the roll. can do.

Furthermore, by providing the outer peripheral wall, it is also possible to increase the area of the cap member supported by the bearing, compared to, for example, a case where the cap main body is supported by the bearing. As a result, the cap member can support the rolled article more stably. In addition, by providing the outer peripheral wall portion on the outer peripheral side of the cap main body, it is possible to prevent a situation where the entire cap member is inserted into the shaft portion.

Means 2. By continuously chamfering from the end face of the first support connection rib on the support part side to the outer peripheral surface of the outer peripheral wall part, the end face of the cap member on the support part side and the outer peripheral surface of the support part are chamfered. 2. The roll storage container according to means 1, wherein the boundary between the container and the container is chamfered.

According to means 3, when the roll-shaped article with the cap member attached is installed in the container body, the position of the roll-shaped article with respect to the container body is slightly shifted, and the outer circumferential surface of the support part and the end face of the cap member Even if the boundary part contacts the container body, the cap member is smoothly guided toward the bearing part due to the chamfered shape of the boundary part, and the cap member can be installed in the bearing part relatively smoothly. In addition, by omitting corners that are relatively easily scraped or damaged at the boundary, foreign matter formed by scraping is prevented from adhering to the roll, and the durability of the cap member is improved. can be done.

The protruding portion 56 has a continuous shape (substantially petal shape), and the protruding portion 56 further includes a first protruding portion 56a and a second protruding portion having a shorter protrusion length toward the outer periphery than the first protruding portion 56a. The protruding portions 56b are alternately arranged. In this embodiment, the diameter of an imaginary circle passing through the tips of the four first protruding portions 56a in the protruding direction is the same as the inner diameter of the shaft portion 8.

As described in detail above, according to the present embodiment, the cap members 5 made of resin are attached to both ends of the shaft portion 8 of the roll-shaped article 7, and the roll-shaped article 7 is passed through the cap member 5 to the container body 2. (bearing part 15). Thereby, 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 prevent deformation of the portion. Furthermore, the cap member 5 (insertion part 52) is a portion of the shaft portion 8 where the roll 9 is wrapped around and deformation is suppressed (a portion closer to the center in the width direction of the roll than the side end surface of the roll 9). It has even been inserted. For this reason, for example, when the cap member 5 is inserted only into a portion of the shaft portion 8 that protrudes outward from the side end surface of the roll 9, the roll-shaped article 7 with the cap member 5 attached is inserted into the container body. 2, it is possible to prevent a situation in which a portion of the shaft portion 8 that protrudes outward from the side end surface of the roll 9 is bent or the like. Therefore, the roll-shaped article 7 can be stably supported (suspended in the air) 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 is configured to support the roll 9 via the shaft portion 8 rather than directly contacting the roll 9, so that the cap member 5 directly presses against the roll 9 and the roll 9 is not deformed. It is also possible to prevent such situations.

Further, the support portion 51 of the cap member 5 has a two-layer structure including a cap body 53 and an outer circumferential wall portion 54 provided so as to surround the outer periphery of the cap body 53. are connected by a support connection rib 55. Thereby, the strength and rigidity of the support portion 51 can be increased. Further, by providing the outer peripheral wall portion 54, the area of the cap member 5 supported by the bearing portion 15 can be increased compared to, for example, a case where the cap body 53 is supported by the bearing portion 15. As a result, the roll-shaped article 7 can be supported more stably using the cap member 5. In addition, by providing the outer peripheral wall portion 54 on the outer peripheral side of the cap 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 between the end surface of the cap member 5 on the support portion 51 side and the outer circumferential surface of the support portion 51 is chamfered. Furthermore, the upper edge of the stopper part 16 of the container body 2 (the boundary between the stopper part 16 and the bearing reinforcing rib 22 provided along the upper edge of the stopper part 16) is shaped like a chamfer. It has become.

Therefore, when installing the roll-shaped article 7 equipped with the cap member 5 in the container body 2, the position of the roll-shaped article 7 with respect to the container body 2 may shift slightly, and the outer peripheral surface of the support portion 51 and the cap member Even if the boundary between the end face of the cap member 5 and the end face of the container body 2 comes into contact with the upper side of the stopper part 16 of the container body 2, the chamfered shape of the boundary allows the cap member 5 to be smoothly guided toward the bearing part 15, making it relatively smooth. The cap member 5 can be smoothly installed on the bearing part 15. In addition, since corners that are relatively easily scraped or damaged are omitted in the boundary portion, foreign matter formed by scraping is prevented from adhering to the roll 9, and the durability of the cap member 5 is increased. can be improved.

In addition, in this embodiment, the container body 2 includes the body side flange portion 14, so that the shaft portion 8 of the roll-shaped article 7 is placed closer to the inside of the roll storage container 1 than the outer edge of the body side flange portion 14. It can be accommodated. Furthermore, by covering the container body 2 containing the roll-shaped article 7 with the lid member 4, the opening of the bearing portion 15 toward 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 in the roll storage container 1 around the bearing part 15 (the end of the shaft part 8) can be closed, and the It is possible to prevent foreign matter from entering the inside of the roll storage container 1.

The container body 2 also includes a cap member 5 that projects upward from the bearing portion 15 and is supported by the bearing portion 15, and a stopper portion 16 that can restrict displacement of the shaft portion 8 toward the outside of the container body 2. ing. Therefore, when the roll storage container 1 is being transported or the like and the roll storage container 1 attempts to shift its position inside the roll storage container 1, the stopper portion 16 prevents the roll storage container 1 from further displacement. I can do it. Therefore, it is possible to prevent the misaligned roll-shaped article 7 from directly colliding with the lid member 4 (covering portion 38). Thereby, concerns regarding the impact resistance of the lid member 4 can be eliminated. As a result, while suppressing the complexity and size of the lid member 4, it is possible to reduce the weight of the lid member 4 and improve the workability of attaching and removing the lid member 4. Moreover, by regulating the positional shift of the roll-shaped article 7 by the stopper part 16 and the part corresponding to the shaft part 8, the roll 9 of the roll-shaped article 7 itself is It is possible to prevent a situation where the inner surface is contacted and damaged.

The stopper part 16 is provided with a cutout part 17, and the end opening of the cap body 53 of the cap member 5 installed (supported) on the bearing part 15 is opened to the container via the cutout part 17. It is exposed on the outside of the main body 2. Therefore, when loading and unloading the rolled article 7 into and out of the container body 2 using the robot arm, the cap member 5 attached to the shaft 8 is supported by the bearing 15, and then the robot arm is moved to the shaft 8. The robot arm can be inserted into the cap member 5 supported by the bearing part 15 and the shaft part 8 while the roll-shaped article 7 is placed in the container body 2.

Furthermore, by providing the stopper portion 16, it is possible to prevent a situation in which the cap member 5 falls off outward from the bearing portion 15. In particular, when the robot arm is pulled out from the shaft portion 8 after the roll-shaped article 7 with the cap member 5 attached thereto is installed in the container body 2 using the robot arm, the robot arm gets caught on the cap member 5 and the cap member It is possible to reliably avoid a situation in which the number 5 falls off. For example, when a relatively long robot arm is inserted from one end side of the shaft part to the other end side when taking out the roll-shaped article 7 installed in the container body 2, the other end It is possible to reliably avoid a situation in which the cap member 5 attached to the part side is pushed out by the robot arm and falls off.

Furthermore, when the lid member 4 of this embodiment is placed over the container body 2, the body-side flange portion 14 provided around the entire circumference of the upper side of the container body 2 and the folded portion 18 are removed from the outside of the container body 2. It has an outer peripheral edge portion 37 that covers from both sides. Further, the covering portion 38 is a part of the outer peripheral edge portion 37, and a 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 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 from entering the inside of the roll storage container 1.

In addition, the container body 2 is provided with a bearing reinforcing rib 22 that is 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 deformation and damage to the bearing portion 15 and the stopper portion 16 can be prevented. Furthermore, main body flange reinforcing ribs 21 are provided at both side positions of the bearing reinforcing ribs 22, and furthermore, in this 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 part 19 but also in the lower range of the lower receiving part 19 (also extending below the lower end of the bearing part 15). As a result, the rigidity of the long-side side wall portion 12 provided with the bearing portion 15 is increased, and 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 part 16, the long-side side walls 12 of the container body 2 are deformed outward, and the distance between the pair of opposing long-side side walls 12 increases. This can prevent the shaft portion 8 (cap member 5) of the roll-shaped article 7 from falling off 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 and damage to the covering portion 38 and the closing portion 43 can be prevented.

Further, the lid member 4 of this embodiment includes a handle portion 34 in a range where a part of the hand can be placed on the upper surface of the lid member 4 and a finger can be hung thereon. In this way, by providing the handle portion 34 at the top of the lid member 4, when attaching and detaching the lid member 4 to the container body 2, it is possible to avoid reaching the lower part of the lid member 4. It is possible to improve work efficiency, etc. In particular, when the upper and lower width (height) of the lid member 4 is relatively long, such as when the upper half of the roll-shaped article 7 is accommodated by the lid member 4, it is necessary to improve the workability of attaching and removing the lid member 4. The effect of achieving this effect is more clearly achieved. In this embodiment, when removing the lid member 4, when placing your hand on the upper part of the lid member 4, you have to bend your back or bend your knees, etc., compared to when you put your hand on the lower part of the lid member 4. Changes in the worker's posture are alleviated. Therefore, it becomes possible to perform the work of attaching and detaching the lid member 4 relatively smoothly.

Furthermore, the lid member 4 is 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 removing the lid member 4 can be improved.

In addition, the top plate portion 31 constituting the upper surface of the lid member 4 is configured in an arch shape. Therefore, while the roll-shaped article 7 is reliably accommodated, the weight of the lid member 4 can be reduced compared to, for example, a case where the lid member 4 is configured 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 due to another article being placed thereon. As a result, it is not necessary to ensure the strength of the lid member 4 assuming that another article is placed thereon, and the lid member 4 can be further reduced in weight.

Further, the handle portion 34 is constructed by making both ends of the top plate portion 31 protrude upward. Therefore, the handle portion 34 can be formed with a relatively simple structure. Furthermore, since the handle portions 34 are provided at both ends of the top plate portion 31, the fingertips of the hand grasping the handle portion 34 can be moved downward from the top surface of the lid member 4, and the fingertips can be moved to the sides of the lid member 4. It can be pressed into contact with the Therefore, the lid member 4 can be made easier to hold while suppressing the upward protrusion length of the handle portion 34.

Note that the present invention is not limited to the content described in the above embodiment, and may be implemented as follows, for example. Of course, other applications and modifications not exemplified below are also possible.

(a) In the above embodiment, the bearing portion 15 has a substantially arc-shaped cross section, but may have a U-shape (with a flat bearing surface) opening upward in cross-section, a substantially V-shape, etc., for example. However, in order to ensure as wide a contact area between the bearing part 15 and the cap member 5 (support part 51) as possible, the cross-sectional shape of the bearing part 15 and the cross-sectional shape of the outer peripheral surface of the support part 51 of the cap member 5 are the same. It is desirable that the shape is . Note that even if the outer circumferential shape of the shaft portion 8 and the shape and size of the bearing surface of the bearing portion 15 do not match, by using the cap member 5, the shaft portion 8 can be suitably connected to the bearing portion 15. can be supported.

Further, in the above embodiment, the lower half of the support portion 51 of the cap member 5 is accommodated in the bearing portion 15, but the depth of the bearing portion 15 is not particularly limited. Alternatively, for example, the entire support portion 51 of the cap member 5 installed on the bearing portion 15 in the height direction may be located below the main body side flange portion 14. However, in order to avoid the vertical width of the outer peripheral edge part 37 (covering part 38) of the lid member 4 from becoming too long, making it difficult to attach and detach the lid member 4, or causing a decrease in the strength of the outer peripheral edge part 37, It is desirable that the upper side of the cap member 5 can be accommodated on the lid member 4 side as well.

Further, although the shape of the notch 17 of the stopper part 16 is not particularly limited, by forming the notch 17, the robot arm can be inserted into the shaft part 8 supported by the bearing part 15. Furthermore, it is desirable that the stopper portion 16 has a shape that does not obstruct insertion of the robot arm. In addition, in the embodiment described above, the bearing part 15 is configured to open to the outside of the container body 2 (although the notch part 17 is formed in the stopper part 16). (the cutout portion 17 may be omitted). Note that it is also possible to omit the stopper portion 16.

(b) In the above embodiment, the bearing reinforcing ribs 22 are provided not only in the upper range of the lower receiving part 19 in the height direction of the container main body 2 but also in the lower range of the lower receiving part 19; The position, number, etc. of the bearing reinforcing ribs 22 are not particularly limited. Only one rib 22 may be provided. However, when the stopper part 16 is provided, it is desirable that the bearing reinforcing rib 22 connected to the stopper part 16 is also provided.

Further, in the above embodiment, the position and number of the covering reinforcing ribs 47 of the lid member 4 are not particularly limited. Only one covered reinforcing rib 47 may be provided.

(c) As shown in FIG. 15, in addition to or instead of the handle part 34 constituted by the lid protrusion 35 of the above embodiment, a recess 61 that constitutes the handle part 34 on the side surface of the lid member 4 It is also possible to provide In this case, it is possible to improve the ease of holding the lid member 4. Further, as in the case where a portion protruding from the side surface of the lid member 4 is provided, a situation in which the protruding portion is easily damaged or the protruding portion impedes nesting of the lid member 4 can be avoided. I can do it. Note that even when the lid protrusion 35 is omitted and the recess 61 is provided, by placing the index finger, middle finger, ring finger, etc. on the recess 61 and by placing the base of the thumb on the top surface of the lid member 4, the lid member 4 can be removed. can be held firmly. Further, the cross-sectional shape of the recess 61 is not particularly limited, and can be changed as appropriate, such as a U-shaped cross-section, a F-shaped cross-section, or an arc-shaped cross-section.

(d) In the above embodiment, the lid member 4 is provided with the outer peripheral edge portion 37 that covers the entire circumference of the upper side of the container body 2 from the outer peripheral side of the container body 2, but the formation range of the outer peripheral edge portion 37 etc. is not particularly limited, and for example, a part of the outer peripheral edge part 37 (or the entire part including the covering part 38) may be omitted in the circumferential direction of the upper side of the container body 2.

Furthermore, the width, number, and shape of the lid protrusions 35 can be changed as appropriate. However, it is desirable that the lid member 4 has a shape that prevents dust from accumulating on the upper surface side. Further, although it is possible to configure the lid member 4 in the shape of a square box, it is possible to reduce the weight by making the lid member 4 have an arcuate cross section according to the shape of the roll-shaped article 7. In addition, it is possible to form the lid protrusion 35 only in the area corresponding to the handle part 34, but it is possible to increase the strength of the top plate part 31 and make it easier to lift it by putting your hand on the handle part 34. In order to prevent deformation of the top plate part 31 when , it is desirable to extend it to the vicinity. Note that it is also possible to omit the handle portion 34.

Further, in the above embodiment, the thickness of the lid member 4 is configured to be thinner than the thickness of the container body 2, but it may be configured such that part or all of the lid member 4 has the same thickness as the container body 2. It's okay. Further, the surface of the handle portion 34 (near the upper end of the corresponding lid protrusion 35) may be processed to increase the frictional force (the uneven processing is the application of tape, etc.). In addition, a reinforcing rib may be provided on the back side of the lid protrusion 35 to connect the constituent walls of the lid protrusion 35.

(e) In the above embodiment, the outer circumferential wall portion 54 of the cap member 5 is configured to have the same diameter at any position in the longitudinal direction of the cap body 53, but the outer circumferential wall portion 54 on the insertion portion 52 side The support portion 51 may have a tapered shape in which the diameter gradually increases from the portion toward the end portion of the support portion 51 . However, if the outer peripheral wall portion 54 is inclined so that the support portion 51 of the cap member 5 and the bearing portion 15 can make surface contact, it is desirable that the bearing portion 15 be similarly inclined.

In addition, instead of the outer circumferential wall portion 54 and the support connection ribs 55, a protrusion protruding outward from the outer circumferential surface of the cap body 53 (for example, a circular protrusion protruding outward from the outer circumferential surface at an intermediate position in the longitudinal direction of the cap body 53) may be used. By providing an annular protrusion (an annular protrusion), a situation in which the entire cap member 5 is inserted into the shaft portion 8 may be prevented. Furthermore, it is also possible to omit the cap body 53 and the support connection ribs 55 (opposed to the outer circumferential wall part 54) in the support part 51. However, in consideration of ensuring the strength of the support part 51 and the sense of stability when the support part 51 is installed on the bearing part 15, as in the above embodiment, the support part 51 is connected to the cap body 53 and the outer peripheral wall part. It is desirable to have a two-layer structure comprising 54.

(f) In the above embodiment, the container body 2, the lid member 4, and the cap member 5 are made of polypropylene, but they may be made of other resin materials such as polyethylene, PET, and polyamide. Further, in the above embodiment, the roll-shaped article 7 including the roll 9 made of plastic film is stored in the roll storage container 1, but the type of roll of the roll-shaped article stored in the roll storage container 1 etc. is not particularly limited and can be changed as appropriate. Further, in the above embodiment, the shaft portion 8 of the roll-shaped article 7 is made of paper, but it may be made of another material (for example, resin, metal, etc.). Here, the structure is such that the cap member 5 is attached to the shaft portion 8, and by matching the material (hardness) of the cap member 5 with the material (hardness) of the container body 2, the shaft portion is made of a different material from the container body 2. Compared to the case where the shaft part 8 is directly installed on the bearing part 15 of the container body 2, it is possible to avoid the situation where the shaft part 8 and the container body 2 come into contact and are damaged (scraped) when the roll-shaped article 7 is put in and taken out. It can be prevented.
