[0036] ===First Embodiment===

[0037] Figure 1A and Figure 1B It is an explanatory diagram of the packaging unit 1 according to the first embodiment. Figure 1A It is an explanatory diagram of the packaging unit 1 in the first form. Figure 1B It is an explanatory diagram of the packaging unit 1 in the second form. Figure 2A and Figure 2B It is an explanatory diagram of the interior of the packaging unit 1. Figure 2A This is an explanatory diagram of the interior of the packaging unit 1 as viewed from the side. Figure 2B This is an explanatory diagram showing the interior of the packaging unit 1 without showing the side plate portion 412 and the cover 42 .

[0038] In the following description, the direction perpendicular to the bottom surface of the package 40 (the upper surface of the bottom 411; the surface supporting the roll 20) is referred to as the "upper and lower directions", and the roll 20 side viewed from the bottom surface of the package 40 is referred to as the "upper" and the opposite side is referred to as the "lower". When the packaging unit 1 is placed on a horizontal plane, the upper and lower directions coincide with the vertical direction. In the following description, the direction perpendicular to the upper and lower directions is sometimes referred to as the lateral direction.

[0039] The packaging unit 1 is a component (unit) that packages the wire 10. Figure 1A and Figure 1B As shown, the packaging unit 1 can be deformed. Figure 1A As shown in FIG. 1 , the form used to package the wire material 10 is referred to as the “first form”. Figure 1B As shown, the mode for extracting the wire material 10 is referred to as a “second mode.” The packaging unit 1 includes the wire material 10 , a packaging body 40 , and a tray 60 .

[0040] The wire 10 is a linear component. The wire 10 includes, for example, cables (electrical wires, optical cables, etc.), wires, tubes, etc. Here, the wire 10 is an optical cable. The wire 10 is packaged in a bent state. Here, the wire 10 is packaged in a wound state. For example, a thick cable with a rigidity of more than 3 mm in an outer diameter is contained in a package 40 in a manner that can be pulled out after being wound for more than 1000 m. In addition, when the outer diameter of the cable is 7 to 11 mm, a cable of 2000 m in length can be contained in a package 40 of 1 m×1 m×1 m size. In the following description, the structure formed by winding the wire 10 is sometimes referred to as a "wound body". However, the wire 10 may also be packaged in a state that is not wound.

[0041] Figure 3A It is an explanatory diagram of an example of the wound body 20 . Figure 3B 2 is an explanatory diagram of another example of a winding body. The winding body 20 is formed by winding the wire 10 while repeatedly reversing the winding direction. By repeatedly reversing the winding direction of the wire 10, Figure 1B When the wire 10 is pulled out from the wound body 20, twisting of the wire 10 can be suppressed. The wound body 20 has a reversing portion 22 in which the wire 10 wound in an S-shape and the wire 10 wound in an inverted S-shape are alternately stacked. Figure 3A The winding body 20 shown has a winding portion 21 that allows the wire 10 to be wound around the outer periphery of the reversal portion 22. Figure 3B As shown, the wound body 20 may not include the encircling portion 21. In addition, the wound body 20 may be configured to wind the wire 10 without reversing the winding direction of the wire 10. The structure of the wound body 20 can be appropriately changed as required.

[0042] The package 40 is a structure for packaging the wire 10 (winding body 20). The package 40 has a storage space for storing the wire 10 (winding body 20). The package 40 can be deformed into a first form and a second form. Here, the package 40 is configured in a box shape. However, the package 40 is not limited to a box-shaped structure, but can also be a skeleton-shaped (frame-shaped) structure. That is, the package 40 has a component that forms a storage space. For example, the component that forms the storage space can be a component that covers the bottom, side, and upper surface of the storage space, or it can be a skeleton. The material of the component that forms the storage space can be, for example, wood, corrugated paper and other paper, metal, FRP, plastic, and a combination thereof. In particular, when the component that forms the storage space is composed of corrugated paper, it is lightweight, easy to disassemble, and recyclable, and does not use chemicals such as preservatives, so it is more suitable for contributing to a sustainable society than metal or wooden drums. The package 40 of the first embodiment has a main body 41 and a cover 42. However, as will be described later, the package 40 may not include a lid.

[0043] The main body 41 is a portion constituting the main body of the package 40. The main body 41 is a portion for packaging the wire 10 (wound body 20). The main body 41 has a bottom 411 and a holding portion 413.

[0044] The bottom portion 411 constitutes the bottom of the main body 41. The bottom portion 411 is a member that supports the wound body 20 from below. Here, the bottom portion 411 is a plate-shaped member, but is not limited to a plate-shaped member as long as it can support the wound body 20.

[0045] The side plate portion 412 is provided in a manner of standing upward from the periphery of the bottom portion 411. The side plate portion 412 constitutes the side surface of the main body portion 41. However, when the main body portion 41 is configured in a skeleton shape, the main body portion 41 may not have the side plate portion 412. In addition, here, the bottom portion 411 and a plurality of (here, 4) side plate portions 412 form a storage space for accommodating the wire 10. The number of the side plate portions 412 is not limited to 4, and may be, for example, 6, 8, etc.

[0046] The holding portion 413 is a component that holds the wire 10 in a coiled shape. In other words, the holding portion 413 is a component that holds the winding body 20. The holding portion 413 is a rod-shaped (cylindrical) component along the up-down direction. The holding portion 413 extends from the bottom 411 toward the upper side. The wire 10 contacts the holding portion 413 to limit the movement of the wire 10, thereby preventing the winding body 20 from collapsing when the wire 10 is drawn out (for example, when packaging, when drawn out, when stored, and when transported). However, the holding portion 413 can be provided as needed, and the holding portion 413 may also be absent.

[0047] Using an example shown in FIG. 3 for explanation, a pair of holding portions 413 are provided near the front and rear of the reversal portion 22 of the winding body 20. In addition, in order to suppress the twisting of the wire 10 when the wire 10 is pulled out, the winding body 20 has a reversal portion 22 that reverses the winding direction of the wire 10 into an S-shape or an inverted S-shape (Z-shape), and in the reversal portion 22, the posture of the wire 10 becomes unstable and easily collapses. Therefore, by arranging the pair of holding portions 413 near the front and rear of the reversal portion 22 (in other words, by arranging the reversal portion 22 of the winding body 20 between the pair of holding portions 413), the shape collapse of the reversal portion 22 can be suppressed.

[0048] The cover 42 is a part that covers the main body 41. The cover 42 is configured to be openable and closable. Figure 1A As shown in FIG. 1 , when the cover 42 is closed (the cover 42 is folded), the cover 42 covers the upper part of the main body 41, and the package 40 is in the first form (a form for packaging the winding body 20 in the package 40). When the wire 10 is pulled out from the package 40, as shown in FIG. Figure 1B As shown, the cover 42 is unfolded, and the cover portion 42A is assembled from the cover 42. The state in which the cover portion 42A is assembled corresponds to the second state of the package 40 (the state for extracting the wire material 10).

[0049] The cover portion 42A is a portion assembled from the cover 42 (multiple cover portions 421 described later). The cover portion 42A is disposed above the main body portion 41 and is disposed at a position higher than the uppermost portion of the package body 40 in the first form (the portion of the package body 40 that is at the highest position; here, the upper surface of the cover 42). A withdrawal port 43 is disposed at the top of the cover portion 42A. Thus, the withdrawal port 43 can be arranged at a high position. However, the withdrawal port 43 only needs to be at a position higher than the uppermost portion of the package body 40 in the first form, and may not be disposed at the top of the cover portion 42A. For example, the withdrawal port 43 may also be disposed on the inclined surface of the cover portion 42A.

[0050] The extraction port 43 is a portion for extracting the wire 10 packaged in the main body 41. The extraction port 43 is set larger than the cross-section of the wire 10, so that the wire 10 can be inserted into the extraction port 43 to extract the wire 10 to the outside. The extraction port 43 is provided at a position higher than the uppermost portion of the package body 40 in the first form. The extraction port 43 of the first embodiment is provided on the cover portion 42A constituted by the cover 42. However, the extraction port 43 may not be provided on the cover portion 42A, and may not be provided on the cover 42 (for example, refer to the second embodiment described later).

[0051] like Figure 1B As shown, the cover 42 has two cover parts 421 (a first cover part 421A and a second cover part 421B). The first cover part 421A is a plate-shaped component, which is disposed on the upper edge (upper side) of the side plate part 412, and rotates (opens and closes) around the upper edge of the side plate part 412. The second cover part 421B is a plate-shaped component, which is disposed on the upper edge of the side plate part 412 opposite to the side plate part 412 on which the first cover part 421A is disposed, and rotates (opens and closes) around the upper edge of the side plate part 412 as an axis. Figure 1A As shown in FIG. 1 , in the first form, the first cover portion 421A and the second cover portion 421B overlap and cover the upper portion of the main body portion 41. Figure 1B As shown, in the second form, the gable roof-shaped cover 42A is assembled by the cover 42 (the first cover part 421A and the second cover part 421B). In the second form, the end edges of the first cover part 421A and the second cover part 421B are connected to each other, thereby stabilizing the posture of the first cover part 421A and the second cover part 421B.

[0052] In the first embodiment, the extraction port 43 is provided in the cover portion 42A. Figure 1BAs shown, a barrel component 44 is installed in the central part of the end edge of the first cover part 421A and the second cover part 421B, and the barrel component 44 constitutes the extraction port 43. That is, the barrel component 44 is arranged at the position connecting the first cover part 421A and the second cover part 421B. In addition, a recess is pre-provided in the central part of the end edge of the first cover part 421A and the second cover part 421B, and the barrel component 44 is installed in the opening formed by the recess. By installing the barrel component 44 at the position connecting the first cover part 421A and the second cover part 421B, it is possible to prevent the wire 10 from entering between the first cover part 421A and the second cover part 421B. However, the extraction port 43 may not be constituted by the barrel component 44 (described later; refer to Figure 5B ).

[0053] Next, the reason why the extraction port 43 is provided at a high position will be described. Figure 4 It is a schematic diagram of the wire 10 , the holding portion 413 , and the extraction port 43 .

[0054] When the packaging unit 1 is viewed from the side, a pair of retaining portions 413 are symmetrically arranged. That is, a pair of retaining portions 413 are arranged at equal distances from the center of the packaging body 40 (refer to the dotted line in the figure). Here, the interval between the outer edges of the pair of retaining portions 413 is set to X. The withdrawal port 43 is arranged on the extension line of the center of the packaging body 40 (refer to the dotted line in the figure). Therefore, the lateral distance between the outer edge of the retaining portion 413 and the withdrawal port 43 is X / 2. In addition, the distance from the bottom surface of the packaging body 40 (the upper surface of the bottom 411) to the front end of the retaining portion 413 (the protruding length of the retaining portion 413 protruding from the bottom surface; the height of the retaining portion 413) is set to Y. In addition, the distance from the bottom surface of the packaging body 40 (the upper surface of the bottom 411) to the withdrawal port 43 (the height of the withdrawal port 43) is set to Z.

[0055] In order to extract the wire 10 extracted from the winding body 20 from the withdrawal port 43, it is necessary to pass over the front end of the holding portion 413. Here, when the wire 10 passes over the front end of the holding portion 413, the angle between the wire 10 on the upper side of the front end of the holding portion 413 (the wire 10 between the front end of the holding portion 413 and the withdrawal port 43) and the horizontal direction is set to θ1, and the angle between the wire 10 on the lower side of the front end of the holding portion 413 (the wire 10 guided by the holding portion 413; the wire 10 between the winding body 20 and the front end of the holding portion 413) and the horizontal direction is set to θ2. In the figure, the state when the angle θ2 is maximum is shown. The angle θ2 is maximum when the wire 10 on the bottom 411 is pulled out. Therefore, the maximum value of the angle θ2 is equivalent to the angle between the line connecting the outer edge of the front end of the retaining portion 413 on one side and the outer edge of the base end of the retaining portion 413 on the other side (the fixed end of the retaining portion 413 and the bottom 411) and the bottom surface of the packaging body 40 (the upper surface of the bottom 411).

[0056] The larger the angle θ1 is, the easier it is for the wire 10 to pass over the front end of the holding portion 413. Therefore, it is preferred that the height Z of the extraction port 43 is as large as possible. In other words, it is preferred that the extraction port 43 is set at a high position. For this reason, the extraction port 43 of the present embodiment is arranged at a position higher than the uppermost portion of the package body 40 in the first form (the upper surface of the cover 42 in the first embodiment) (see Figure 1B ).

[0057] In addition, the larger the angle θ1 is compared to the angle θ2, the easier it is for the wire 10 to pass over the front end of the holding portion 413. Therefore, it is preferred that the angle θ1 is greater than the angle θ2. Figure 4 As shown, when the height Z of the extraction port 43 is 1.5 times the height Y of the holding portion 413 , the maximum values ​​of the angles θ1 and θ2 are equal. Therefore, the height Z of the extraction port 43 is preferably 1.5 times or more the height Y of the holding portion 413 .

[0058] like Figure 4 As shown, the wire 10 needs to pass over the front end of the holding portion 413, so it is preferred that the front end of the holding portion 413 is a shape that is easy for the wire 10 to pass over. Therefore, the holding portion 413 may also be a shape that is thinner as it approaches the front end side. In addition, the front end of the holding portion 413 may also be rounded when viewed from the side.

[0059] In addition, the main body 41 may not include the holding portion 413. Even if the main body 41 does not include the holding portion 413, if the extraction port 43 is set at a high position, the angle between the center line of the extraction port 43 and the wire 10 can be reduced, and the wire 10 can be easily extracted from the extraction port 43. Therefore, even if the main body 41 does not include the holding portion 413, it is advantageous to set the extraction port 43 at a high position, and thus the extraction port 43 is preferably arranged at a position higher than the uppermost portion of the package body 40 in the first form.

[0060] The pallet 60 is a component that serves as the base of the packaging body 40. The pallet 60 serves as a platform used, for example, when the packaging unit 1 is moved by a forklift. The pallet 60 may also have a lower plate portion 61 and a spacer 62. The lower plate portion 61 is a plate-shaped portion that constitutes the lower surface of the pallet 60. The spacer 62 is a component that is arranged between the packaging body 40 (bottom portion 411) and the lower plate portion 61. A gap is formed between the bottom portion 411 and the lower plate portion 61 by the spacer 62, and the fork of the forklift is inserted into the gap. In addition, the lower plate portion 61 may not be provided, and a gap may be formed on the lower side of the packaging body 40 only by the spacer 62. The packaging unit 1 may not have the pallet 60.

[0061] like Figure 2AAs shown, the retaining portion 413 passes through the bottom 411 of the package body 40, and the lower end of the retaining portion 413 is fixed to the lower plate portion 61 of the tray 60. The retaining portion 413 is fixed at two locations, the bottom 411 of the package body 40 and the lower plate portion 61 of the tray 60. The bottom 411 and the lower plate portion 61 are spaced apart in the up-down direction by the spacer 62, so the retaining portion 413 is fixed at two locations spaced apart in the up-down direction. As a result, the retaining portion 413 becomes a structure that is not easy to tip over. However, the retaining portion 413 does not need to pass through the bottom 411 of the package body 40, and the lower end of the retaining portion 413 is fixed to the bottom 411 of the package body 40.

[0062] <Modification>

[0063] Figure 5A and Figure 5B It is an explanatory diagram of a first modified example of the packaging unit 1 of the first embodiment. Figure 5A This is a diagram showing the packaging unit 1 in a state where the cover 42 is opened, as viewed from above. Figure 5B It is an explanatory diagram of the packaging unit 1 in the second form.

[0064] In the first modification, the cover 42 also includes a first cover portion 421A and a second cover portion 421B, and a recess is provided at the center of the end edge of the first cover portion 421A and the second cover portion 421B. In the first modification, after the first cover portion 421A and the second cover portion 421B are assembled to form the cover portion 42A, the cylinder member 44 is not mounted on the recess, and the extraction port 43 is formed by the recess of the first cover portion 421A and the second cover portion 421B. In this way, the extraction port 43 may not be formed by the cylinder member 44.

[0065] Fig. 6A and Figure 6B It is an explanatory diagram of a second modified example of the packaging unit 1 of the first embodiment.

[0066] In the second modification, the cover 42 also has a first cover portion 421A and a second cover portion 421B. In the second modification, a coupling portion 422 is provided at the end edges of the first cover portion 421A and the second cover portion 421B. The coupling portion 422 is a portion that is coupled to other components when the cover portion 42A is assembled. The coupling portion 422 of the first cover portion 421A is coupled to the coupling portion 422 of the second cover portion 421B, thereby stabilizing the postures of the first cover portion 421A and the second cover portion 421B and improving the strength of the cover portion 42A.

[0067] Here, the coupling portion 422 is configured as a concave-convex shape, and the concave-convex of the first cover portion 421A and the concave-convex of the second cover portion 421B mesh with each other, thereby coupling the end edges of the first cover portion 421A and the second cover portion 421B to each other. However, the coupling portion 422 is not limited to the concave-convex shape. For example, the coupling portion of one side of the first cover portion 421A and the second cover portion 421B may be set as an insertion piece, and the coupling portion of the other side may be set as a slit, and the end edges of the first cover portion 421A and the second cover portion 421B may be coupled to each other by inserting the insertion piece into the slit. However, in the case of Fig. 6A and Figure 6B When the coupling portion 422 is constructed into a concave-convex shape as shown, the coupling portion 422 of the first cover portion 421A can be coupled with the coupling portion 422 of the second cover portion 421B only by opening and closing the first cover portion 421A and the second cover portion 421B, so there is no need to insert the insertion piece into the slit, thereby facilitating the assembly operation of the cover portion 42A.

[0068] Fig. 7A and Figure 7B It is an explanatory diagram of a third modified example of the packaging unit 1 of the first embodiment.

[0069] In the third variant, the cover 42 also has a first cover portion 421A and a second cover portion 421B. In addition, in the third variant, the cover 42 has a wing portion 423. The wing portion 423 is a plate-shaped portion that blocks the gap of the cover portion 42A. The wing portion 423 is arranged on the upper edge (upper side) of the side plate portion 412 where the first cover portion 421A or the second cover portion 421B is not arranged, and rotates (opens and closes) with the upper edge of the side plate portion 412 as an axis. When the gable roof-shaped cover portion 42A is assembled by the first cover portion 421A and the second cover portion 421B, the side edges of the first cover portion 421A and the second cover portion 421B are connected to the side edges of the wing portion 423. Thus, the gap on the side of the gable roof-shaped cover portion 42A can be blocked by the wing portion 423. In the third modification, as in the connection part 422 of the second modification, connection parts may be provided at the side edges of the first cover part 421A and the second cover part 421B and the side edges of the wing part 423, respectively, so that the connection part of the first cover part 421A or the second cover part 421B is connected to the connection part of the wing part 423. Thus, the strength of the cover part 42A is improved.

[0070] Fig. 8A and Figure 8B It is an explanatory diagram of a fourth modified example of the packaging unit 1 of the first embodiment.

[0071] In the fourth modification, the cover 42 has a plurality of (here, 4) cover portions 421. Each cover portion 421 is provided on the upper edge (upper side) of each of the plurality of side plate portions 412 of the main body 41. By connecting the side edges of the four cover portions 421 to each other, a square roof-shaped (truncated cone-shaped) cover portion 42A is assembled. In the fourth modification, the end edges of the plurality of cover portions 421 constitute the extraction port 43. In addition, the barrel member 44 may be mounted on the opening portion constituted by the end edges of the plurality of cover portions 421, whereby the extraction port 43 is constituted by the barrel member 44. By constituting the extraction port 43 with the barrel member 44, it is possible to suppress the wire 10 from entering between the cover portions 421. In addition, in the fourth modification, a coupling portion may be provided on the side edge of each cover portion 421, as in the coupling portion 422 of the second modification, so that the coupling portions of the cover portions 421 are coupled to each other. Thus, the strength of the cover portion 42A is improved.

[0072] Fig. 9A and Fig. 9B It is an explanatory diagram of a fifth modified example of the packaging unit 1 of the first embodiment.

[0073] In the fifth modification, the recess 424 is formed at the edge of the cover 421 constituting the extraction port 43, which is different from the fourth modification ( Fig. 8A and Figure 8B ) is different. A recess 424 is formed at the end edge of the cover 421, thereby arranging the recess 424 around the edge of the withdrawal port 43. When the wire 10 is withdrawn from the withdrawal port 43, the wire 10 enters the recess 424, thereby stabilizing the position of the withdrawn wire 10 at the position of the recess 424. In the fifth modification, the wire 10 can be prevented from entering between the cover 421 without using the barrel member 44.

[0074] Fig. 10A and Fig. 10B It is an explanatory diagram of a sixth modified example of the packaging unit 1 of the first embodiment.

[0075] In the sixth modification, the cover 42 also has a plurality of (here, 4) cover portions 421. Each cover portion 421 has an upper surface portion 425. The upper surface portion 425 is a plate-shaped portion constituting the upper surface of the cover portion 42A. The upper surface portion 425 is provided at the end edge of the cover portion 421 on the side opposite to the side plate portion 412. A hole 425A is formed in the upper surface portion 425, and the extraction port 43 is constituted by the hole 425A. Here, the upper surface portion 425 is provided on each of the four cover portions 421, and the four upper surface portions 425 overlap to constitute the upper surface of the cover portion 42A. However, it is sufficient as long as the upper surface portion 42 is provided on at least one cover portion 421. According to the sixth modification, it is possible to suppress the wire 10 from entering between the cover portions 421.

[0076] In the first embodiment including the first to sixth modified examples, the extraction port 43 in the second form is located at a position higher than the uppermost portion of the package body 40 in the first form. Thus, the extraction port 43 can be located at a high position by deforming the packaging unit 1, so that the wire 10 can be easily extracted by a simple structure.

[0077] In addition, in the first embodiment including the first to sixth modified examples described above, the package body 40 has a plurality of cover portions 421, and the extraction port 43 is provided in the cover portion 42A assembled from the cover portions 421. Thus, the extraction port 43 can be provided at a high position using the cover 42, thereby improving the extraction performance of the wire without preparing a structure such as an arm.

[0078] <Experimental example>

[0079] Production Figure 1A and Figure 1B The packaging unit 1 shown was used to evaluate the extraction performance of the optical cable (equivalent to the wire 10). Here, packaging units 1 were produced in which the distance between a pair of retaining portions 413 was 700 mm, the height Y of the retaining portion 413 was 720 mm, and the height Z of the extraction port 43 was different within the range of 810 mm to 1500 mm. In addition, the diameter of the optical cable was 7 mm. In the evaluation of the extraction performance, when the optical cable was extracted from the extraction port 43 without pulling it with excessive force, it was evaluated as good (○), when the optical cable was extracted from the extraction port 43 only by pulling it with strong force, it was evaluated as qualified (△), and when the optical cable could not be extracted, it was evaluated as unqualified (×).

[0080] Table 1 shows the evaluation results of the extraction performance of each packaging unit 1 having different heights Z of the extraction port 43 .

[0081] [Table 1]

[0082]

[0083] △: The optical cable can only be pulled out by pulling it hard

[0084] ○: The optical cable is pulled out without excessive force

[0085] As shown in Table 1, when the height Z of the withdrawal outlet 43 is 1.5 times or more of the height Y of the holding portion 413, the optical cable can be pulled out from the withdrawal outlet 43 without pulling the optical cable with excessive force. In this way, it was confirmed that as long as the height Z of the withdrawal outlet 43 is 1.5 times or more of the height Y of the holding portion 413, the wire 10 can easily pass over the front end of the holding portion 413. In addition, even in the case of Z / Y=1.46, the optical cable was pulled out from the withdrawal outlet 43. In this way, even if the height Z of the withdrawal outlet 43 is less than 1.5 times the height Y of the holding portion 413, the optical cable can be pulled out from the withdrawal outlet 43 as long as it is possible to resist the optical cable from being hooked on the holding portion 413. However, it was confirmed that as long as the height Z of the withdrawal outlet 43 is 1.5 times or more of the height Y of the holding portion 413, it is not necessary to resist the optical cable from being hooked on the holding portion 413, so it becomes easier to pull out compared with the case where the height Z of the withdrawal outlet 43 is less than 1.5 times the height Y of the holding portion 413. In addition, as Figure 4 As shown in FIG. 1 , as long as the height Z of the extraction port 43 is 1.5 times or more of the height Y of the holding portion 413, the wire 10 can easily pass over the front end of the holding portion 413. Figure 1A and Figure 1B The packaging unit 1 shown is different from the packaging unit 1 in the case of Figure 1A and Figure 1B Similarly, in the packaging unit 1 shown, if the height Z of the extraction port 43 is 1.5 times or more the height Y of the holding portion 413 , extraction becomes easier than when the height Z of the extraction port 43 is less than 1.5 times the height Y of the holding portion 413 .

[0086] ===Second Embodiment===

[0087] Fig.11A and Fig. 11B It is an explanatory diagram of the packaging unit 1 according to the second embodiment. Fig.11A It is an explanatory diagram of the packaging unit 1 in the first form. Fig. 11B It is an explanatory diagram of the packaging unit 1 in the second form. Figures 12A to 12C It is an explanatory diagram of the lifting unit 50 . Fig. 12A This is a diagram showing the packaging unit 1 as viewed from above. Fig. 12B It is an explanatory diagram of the lifting unit 50 in the first form. Fig. 12C 2 is an explanatory diagram of the lifting unit 50 in the second form. Fig. 12B and Fig. 12C In order to illustrate the lifting unit 50 (and the winding body 20), the side plate portion 412 is not shown.

[0088] In the second embodiment, the packaging unit 1 also includes the winding body 20, the packaging body 40, and the tray 60. In the second embodiment, the lifting unit 50 may not include the tray 60. The packaging body 40 of the second embodiment further includes the lifting unit 50. In addition, the packaging body 40 of the second embodiment may include the cover 42 as in the first embodiment, or may not include the cover 42.

[0089] The lifting unit 50 is a component that raises and lowers the extraction port 43. When the package 40 is in the first form (a form for packaging the winding body 20 in the package 40), the lifting unit 50 is in a state where the extraction port 43 is lowered and is accommodated in the package 40 (main body 41). In addition, when the package 40 is provided with a cover 42, the lifting unit 50 is in a state where the extraction port 43 is lowered, and the cover 42 (not shown) is closed, and the lifting unit 50 can be packaged in the package 40. When the package 40 is in the second form (a form for extracting the wire 10), the lifting unit 50 is in a state where the extraction port 43 is raised, and the extraction port 43 is in a position higher than the uppermost part of the package 40 in the first form (the part of the package 40 that is in the highest position; in the case of having the cover 42, it is the upper surface of the cover 42; in the case of not having the cover 42, it is the upper edge of the main body 41). Furthermore, when the package 40 includes the cover 42 , when the package 40 is deformed from the first form to the second form, after the cover 42 is opened, the lifting unit 50 is used to position the extraction port 43 at a high position.

[0090] The lifting unit 50 includes a moving body 51 having the extraction port 43 and a telescopic member 52 .

[0091] The movable body 51 is a component that moves (lifts and lowers) in the up-down direction. When the package body 40 is in the first form (a form for packaging the wire 10), the movable body 51 is in a lowered position and is packaged in the main body 41. When the package body 40 is in the second form (a form for extracting the wire 10), the movable body 51 is in an ascended position, becoming a position higher than the uppermost part of the package body 40 in the first form. The movable body 51 has a withdrawal port 43 and a connecting portion 511. In the second embodiment, the withdrawal port 43 is provided on the movable body 51, and the cover 42 of the package body 40 is not provided. The connecting portion 511 is a portion that connects the withdrawal port 43 to the telescopic component 52. One end of the connecting portion 511 is connected to the withdrawal port 43, and the other end of the connecting portion 511 is connected to the telescopic component 52 (specifically, the front end of the telescopic component 52). Figures 12A to 12C The extraction port 43 and the connecting portion 511 shown are composed of the same member (rod-shaped member). However, the member constituting the extraction port 43 and the member constituting the connecting portion 511 may be constituted by different members (described later; see Fig. 14C ).

[0092] like Fig.11A As shown, when the package body 40 is in the first form (a form for packaging the wire 10), the moving body 51 is arranged below the front end of the holding portion 413. Thus, it is possible to suppress the wire 10 of the winding body 20 from detaching from the holding portion 413 in the first form. However, in the first form, the moving body 51 may also be arranged above the holding portion 413 (however, below the uppermost portion of the package body 40 in the first form).

[0093] In addition, if Fig.11A As shown, when the package 40 is in the first form (a form for packaging the wire 10), the moving body 51 contacts the upper surface of the winding body 20 (contacts the wire 10 constituting the upper surface of the winding body 20). As a result, the wire 10 of the winding body 20 can be pressed in the first form, thereby suppressing the collapse of the winding body 20. However, even if the moving body 51 does not contact the wire 10 of the winding body 20, as long as the moving body 51 is arranged below the front end of the holding portion 413, it is possible to suppress the wire 10 of the winding body 20 from detaching from the holding portion 413.

[0094] The telescopic component 52 is a component that is telescopic in the up-down direction. The telescopic component 52 is a component that moves (lifts and lowers) the moving body 51 in the up-down direction. The telescopic component 52 is a component that is in the up-down direction and extends from the bottom 411 toward the upper side. The lower end of the telescopic component 52 in the figure is fixed to the bottom 411. However, as with the above-mentioned retaining portion 413, the telescopic component 52 can also pass through the bottom 411 of the packaging body 40, and the telescopic component 52 is fixed at the bottom 411 and the lower plate portion 61 of the tray 60. As a result, the telescopic component 52 becomes a structure that is not easy to tip over. The moving body 51 (specifically, the connecting portion 511) is fixed at the upper end of the telescopic component 52. The telescopic component 52 is telescoped, so that the moving body 51 moves (lifts and lowers) in the up-down direction. A plurality of telescopic components 52 are arranged on the outside of the winding body 20, and are arranged at intervals in the circumferential direction in a manner to surround the winding body 20. Here, four telescopic components 52 are arranged at 90-degree intervals on the outer periphery of the winding body 20.

[0095] Fig.13 It is an explanatory diagram of an example of the structure of the telescopic member 52.

[0096] The telescopic member 52 includes an upper member 521, a lower member 522, and a fixing portion 523. The upper member 521 and the lower member 522 are members extending in the up-down direction. The upper member 521 slides upward relative to the lower member 522, thereby extending the telescopic member 52. In addition, the telescopic member 52 may be extended by connecting the upper member 521 and the lower member 522 with a hinge and expanding the angle of the hinge (in other words, by unfolding the folded upper member 521 and the lower member 522). The telescopic member 52 may also be provided with a plurality of stages. Fig.13 The structure shown in the figure can be extended and retracted in multiple stages. Here, the upper component 521 and the lower component 522 are configured as a cylinder, the outer diameter of the upper component 521 is smaller than the inner diameter of the lower component 522, and the upper component 521 is arranged on the inner side of the lower component 522. The fixing part 523 fixes the upper component 521 and the lower component 522, and fixes them in a state where the telescopic component 52 is stretched. The fixing part 523 in the figure is provided on the upper component 521, and has a protrusion that is biased toward the outside by a spring. If the upper component 521 moves upward relative to the lower component 522, the protrusion of the fixing part 523 enters the fitting hole of the lower component 522, thereby fixing the upper component 521 and the lower component 522. As described above, it is preferred that the fixing part 523 is a structure that automatically fixes the upper component 521 and the lower component 522 if the upper component 521 is moved to a specified position relative to the lower component 522. Thus, for example, compared with the case where the upper member 521 and the lower member 522 are fixed by screws, the operation of fixing the telescopic member 52 in the extended state becomes easier. In particular, when the plurality of telescopic members 52 need to be extended simultaneously when the movable body 51 (extraction port 43) is raised, if the fixing portion 523 is configured to automatically fix the upper member 521 and the lower member 522, the operation of fixing the movable body 51 (extraction port 43) in the raised state becomes easier.

[0097] In addition, the fixing portion 523 is not limited to Fig.13 For example, the fixing portion 523 may be provided on the lower member 522 and may have a protrusion that is urged inward, and the protrusion of the fixing portion may enter the fitting hole of the upper member 521, thereby fixing the upper member 521 and the lower member 522. Fig.13The structure of applying force to the protrusion by a spring as shown in the figure. For example, a taper may be provided on the outer surface of the upper component 521 and the inner surface of the lower component 522, and the upper component 521 may move upward relative to the lower component 522, thereby making the outer surface of the upper component 521 fit with the inner surface of the lower component 522, and fixing the telescopic component 52 in a state where the telescopic component 52 is extended. Even in the structure where the tapered surfaces fit together, when the upper component 521 is moved to a predetermined position relative to the lower component 522, the upper component 521 and the lower component 522 can be automatically fixed. However, the fixing part 523 is not limited to the structure that automatically fixes the upper component 521 and the lower component 522, and the upper component 521 and the lower component 522 may be fixed by screws, pins, locking rods, etc. In addition, the upper component 521 and the lower component 522 are not limited to cylindrical components, and may be composed of rod-shaped or plate-shaped components, for example. In addition, the fixing part 523 may not be equipped on the lifting unit 50 itself. However, if the lifting unit 50 includes the fixing portion 523 , it becomes easy to perform the fixing operation in the extended state of the telescopic member 52 .

[0098] Figures 14A to 14C It is an explanatory diagram of a modified example of the lifting unit 50 .

[0099] Fig.14A The lifting unit 50 of the first modified example shown has a moving body 51 and telescopic parts 52. As for the telescopic parts 52, four telescopic parts 52 are arranged at intervals of 90 degrees on the outer periphery of the winding body 20. The moving body 51 has two intersecting bridge parts 512. The bridge part 512 is a part that is bridged between the front ends of the two opposing telescopic parts 52. Each bridge part 512 is composed of a pair of parallel rod parts. The part where the two bridge parts 512 intersect constitutes the extraction port 43, and the part other than that constitutes the connecting part 511.

[0100] exist Fig. 14B In the second modification shown, the lifting unit 50 also has a moving body 51 and a telescopic member 52. In the second modification, the lifting unit 50 has two telescopic members 52, and a bridge portion 512 is provided in a manner that bridges the front ends of the two telescopic members 52. In the second modification, the extraction port 43 is formed in the central portion of the bridge portion 512, and the connecting portion 511 is formed by the other portion. As shown in the second modification, the telescopic members 52 may not be arranged on the outer periphery of the winding body 20 at intervals of 90 degrees.

[0101] exist Fig. 14CIn the third modified example shown, the lifting unit 50 also has a moving body 51 and a telescopic member 52. The moving body 51 of the third modified example has an extraction port 43 formed by a circular ring member 513, and a rope member (equivalent to a connecting portion 511) connecting the extraction port 43 (circular ring member 513) and the telescopic member 52. In this way, the extraction port 43 and the connecting portion 511 may not be formed by a rod-shaped member.

[0102] In the second embodiment including the first to third modified examples, similarly to the first embodiment, the extraction port 43 in the second form is located at a position higher than the uppermost portion of the package body 40 in the first form. Thus, the extraction port 43 can be located at a high position by deforming the packaging unit 1, thereby improving the extraction performance of the wire without preparing a structure such as an arm.

[0103] In addition, in the second embodiment including the first to third modified examples described above, unlike the first embodiment, the package body 40 includes: a moving body 51 having a withdrawal port 43; and a telescopic member 52. Thus, by extending the telescopic member 52, the withdrawal port 43 can be located at a high position. In addition, the lifting unit 50 is packaged in the package body 40, so that when the wire 10 is withdrawn, a withdrawal device having a structure independent of the packaging unit 1 is not required.

[0104] Furthermore, in the second embodiment including the first to third modified examples described above, Figure 4 Therefore, in the second embodiment including the first to third modified examples, the height Z of the extraction port 43 is preferably 1.5 times or more the height Y of the holding portion 413 , as in the first embodiment.
