===First embodiment===
FIG. 1A and FIG. 1B are explanatory diagrams of the packaging unit 1 of the first embodiment. FIG. 1A is an explanatory diagram of the packaging unit 1 of the first embodiment. FIG. 1B is an explanatory diagram of the packaging unit 1 of the second embodiment. 2A and 2B are explanatory diagrams of the inside of the packaging unit 1. FIG. 2A is an explanatory diagram of the inside of the packaging unit 1 viewed from the side. FIG. 2B is an explanatory diagram showing the inside of the packaging unit 1 with the side plate portion 412 and the lid 42 not shown.

In the following description, the direction perpendicular to the bottom surface of the package 40 (the top surface of the bottom part 411; the surface that supports the wound body 20) is referred to as the "up-down direction", and the side of the wound body 20 when viewed from the bottom surface of the package 40 is referred to as the "vertical direction". is considered "top" and the opposite side is "bottom". When the packaging unit 1 is placed on a horizontal surface, the vertical direction coincides with the vertical direction. Furthermore, in the following description, a direction perpendicular to the up-down direction may be referred to as a lateral direction.

The packing unit 1 is a member (unit) in which the wire rod 10 is packed. As shown in FIGS. 1A and 1B, the packaging unit 1 can be modified in shape. As shown in FIG. 1A, the form for packing the wire rod 10 is referred to as a "first form". As shown in FIG. 1B, the form for drawing out the wire rod 10 is referred to as a "second form". The packaging unit 1 includes a wire rod 10, a package 40, and a pallet 60.

The wire rod 10 is a linear member. The wire 10 includes, for example, a cable (such as an electric cable or an optical cable), a wire, a tube, and the like. Here, the wire 10 is an optical cable. The wire rod 10 is packed in a bent state. Here, the wire rod 10 is packaged in a wound state. For example, a thick, rigid cable with an outer diameter of 3 mm or more is wound over 1000 m or more and is housed in the package 40 so that it can be pulled out. Note that when the outer diameter of the cable is 7 to 11 mm, a cable with a length of 2000 m can be accommodated in the package 40 with a size of 1 m x 1 m x 1 m. In the following description, a structure in which the wire rod 10 is wound may be referred to as a "wound body." However, the wire 10 does not need to be packaged in a wound state.

FIG. 3A is an explanatory diagram of an example of the wound body 20. FIG. 3B is an explanatory diagram of another example of the wound body. The wound body 20 is constructed by winding the wire rod 10 while repeatedly reversing the winding direction. By repeatedly reversing the winding direction of the wire 10, twisting of the wire 10 can be suppressed when the wire 10 is pulled out from the wound body 20 as shown in FIG. 1B. The wound body 20 has an inverted portion 22 in which wire rods 10 wound in an S-shape and wire rods 10 wound in an inverted S-shape are alternately stacked. The wound body 20 shown in FIG. 3A has a winding part 21 in which the wire rod 10 is wound around the outer periphery of the reversing part 22. Note that, as shown in FIG. 3B, the wound body 20 does not need to include the circumferential portion 21. Moreover, the wound body 20 may be configured by winding the wire rod 10 without reversing the winding direction of the wire rod 10. The configuration of the wound body 20 can be changed as required.

The packing body 40 is a structure for packing the wire rod 10 (wound body 20). The package 40 has an accommodation space that accommodates the wire rod 10 (wound body 20). The package 40 can be transformed 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-like structure, but may be a frame-like structure. That is, the package 40 has a member that forms a housing space. For example, the member forming the accommodation space may be a member that covers the bottom, side surfaces, and top surface of the accommodation space, or may be a frame. Examples of the material of the member forming the accommodation space include wood, paper such as cardboard, metal, FRP, plastic, and combinations thereof. In particular, when the storage space is made of cardboard, it is lightweight, easy to disassemble, and recyclable, and does not use chemicals such as preservatives, so it is better than metal or wooden drums. Suitable for contributing to a sustainable society. The package 40 of the first embodiment includes a main body 41 and a lid 42. However, as will be described later, the package 40 does not need to have a lid.

The main body portion 41 is a part that constitutes the main body of the package 40. The main body portion 41 is a portion where the wire rod 10 (wound body 20) is packed. The main body portion 41 has a bottom portion 411 and a holding portion 413.

The bottom portion 411 constitutes the bottom of the main body portion 41 . The bottom portion 411 serves as a member that supports the wound body 20 from below. Although the bottom portion 411 is a plate-shaped member here, it is not limited to a plate-shaped member as long as it can support the wound body 20.
A side plate portion 412 is provided so as to rise upward from the periphery of the bottom portion 411 . The side plate portion 412 constitutes a side surface of the main body portion 41 . However, when the main body part 41 is configured in a frame shape, the main body part 41 does not need to include the side plate part 412. Note that here, an accommodation space for accommodating the wire rod 10 is formed by the bottom portion 411 and a plurality of (four in this case) side plate portions 412. The number of side plates 412 is not limited to four, and may be six or eight, for example.
The holding portion 413 is a member that holds the wire 10 in a wound shape. In other words, the holding part 413 is a member that holds the wound body 20. The holding portion 413 is a rod-shaped (cylindrical) member extending in the vertical direction. The holding part 413 extends upward from the bottom part 411. Since the movement of the wire rod 10 is restricted when the wire rod 10 comes into contact with the holding part 413, it is possible to prevent the wound body 20 from collapsing when the wire rod 10 is pulled out (for example, during packaging, pulling out, storage, or transportation). It can be suppressed. However, the holding part 413 may be installed as needed, and the holding part 413 may be omitted.

To explain using an example shown in FIG. 3, the pair of holding parts 413 are provided near the front and back of the inverted part 22 of the wound body 20, respectively. In addition, in order to suppress twisting of the wire 10 when the wire 10 is pulled out, the wound body 20 has an inverted portion in which the winding direction of the wire 10 is reversed in an S-shape or an inverted S-shape (Z-shape). 22, and the posture of the wire rod 10 becomes unstable at this reversal portion 22 and is likely to collapse. Therefore, by disposing the pair of holding parts 413 near the front and rear of the reversing part 22 (in other words, by disposing the reversing part 22 of the wound body 20 between the pair of holding parts 413). ), it is possible to suppress the shape of the reversing portion 22 from collapsing.

The lid 42 is a part that covers the main body part 41. The lid 42 is configured to be openable and closable. As shown in FIG. 1A, when the lid 42 is closed (the lid 42 is folded), the lid 42 covers the upper part of the main body 41, and the package 40 is in the first form (a rolled body). 20 into a package 40). When the wire rod 10 is pulled out from the package 40, the lid 42 is unfolded and the hood portion 42A is assembled with the lid 42, as shown in FIG. 1B. The assembled form of the hood portion 42A corresponds to the second form of the package 40 (a form for pulling out the wire 10).

The hood part 42A is a part assembled with a lid 42 (a plurality of lid parts 421 described later). The hood portion 42A is provided above the main body portion 41, and is provided at a higher position than the top of the package 40 in the first embodiment (the highest portion of the package 40; here, the top surface of the lid 42). . An outlet 43 is provided at the top of the hood portion 42A. Thereby, the outlet 43 can be arranged at a high position. However, the outlet 43 only needs to be located at a higher position than the top of the package 40 in the first embodiment, and does not need to be provided at the top of the hood part 42A. For example, the outlet 43 may be provided on the inclined surface of the hood portion 42A.

The outlet 43 is a part from which the wire 10 packed in the main body 41 is pulled out. Since the outlet 43 is set larger than the cross section of the wire 10, the wire 10 can be inserted through the outlet 43 and drawn out to the outside. The outlet 43 is provided at a higher position than the top of the package 40 in the first embodiment. The outlet 43 of the first embodiment is provided in the hood portion 42A formed by the lid 42. However, the outlet 43 may not be provided in the hood portion 42A or may not be provided in the lid 42 (for example, see the second embodiment described below).

As shown in FIG. 1B, the lid 42 has two lid parts 421 (a first lid part 421A and a second lid part 421B). The first lid portion 421A is a plate-shaped member, is provided on the upper edge (upper side) of the side plate portion 412, and rotates (opens and closes) around the upper edge of the side plate portion 412. The second lid part 421B is a plate-shaped member, and is provided on the upper edge of the side plate part 412 facing the side plate part 412 on which the first lid part 421A is provided, and is centered around the upper edge of the side plate part 412. Rotate (open and close). As shown in FIG. 1A, in the first form, the first lid part 421A and the second lid part 421B cover the upper part of the main body part 41 in an overlapping state. As shown in FIG. 1B, in the second embodiment, a gable roof-shaped hood portion 42A is assembled by the lid 42 (the first lid portion 421A and the second lid portion 421B). In the second form, the edges of the first lid part 421A and the second lid part 421B are connected to each other, so that the postures of the first lid part 421A and the second lid part 421B are stabilized.

In the first embodiment, the outlet 43 is provided in the hood portion 42A. Here, as shown in FIG. 1B, a cylindrical member 44 is attached to the central part of the edge of the first lid part 421A and the second lid part 421B, and this cylindrical member 44 constitutes the outlet 43. That is, the cylindrical member 44 is provided at a portion that connects the first lid part 421A and the second lid part 421B. Note that a recess is provided in advance at the center of the edge of the first lid 421A and the second lid 421B, and the cylindrical member 44 is attached to the opening defined by the recess. By attaching the cylindrical member 44 to the region connecting the first lid part 421A and the second lid part 421B, it is possible to suppress the wire 10 from entering between the first lid part 421A and the second lid part 421B. However, the outlet 43 does not need to be composed of the cylindrical member 44 (described later; see FIG. 5B).

Next, the reason why the outlet 43 is provided at a high position will be explained. FIG. 4 is a schematic diagram of the wire 10, the holding part 413, and the outlet 43.

When the packaging unit 1 is viewed from the side, the pair of holding parts 413 are arranged symmetrically. That is, the pair of holding parts 413 are arranged at the same distance from the center of the package 40 (see dotted line in the figure). Here, the distance between the outer edges of the pair of holding parts 413 is assumed to be X. The outlet 43 is arranged on an extension of the center of the package 40 (see the dotted line in the figure). Therefore, the distance in the lateral direction between the outer edge of the holding portion 413 and the outlet 43 is X/2. Further, the distance from the bottom surface of the package 40 (the top surface of the bottom portion 411) to the tip of the holding portion 413 (the protruding length of the holding portion 413 from the bottom surface; the height of the holding portion 413) is defined as Y. Further, the distance from the bottom surface of the package 40 (the top surface of the bottom portion 411) to the outlet 43 (the height of the outlet 43) is defined as Z.

In order to pull out the wire 10 drawn out from the wound body 20 from the outlet 43, it is necessary to get over the tip of the holding part 413. Here, when the wire rod 10 passes over the tip of the holding section 413, the angle that the wire rod 10 above the tip of the holding section 413 (the wire rod 10 between the tip of the holding section 413 and the outlet 43) makes with the lateral direction is calculated. θ ₁ , and the wire rod 10 below the tip of the holding portion 413 (the wire rod 10 guided by the holding portion 413; the wire rod 10 between the winding body 20 and the tip of the holding portion 413) forms the horizontal direction. Let the angle be θ ₂ . The figure shows the state when the angle θ ₂ is at its maximum. The angle θ ₂ is at its maximum when the wire 10 on the bottom 411 is pulled out. Therefore, the maximum value of the angle θ ₂ is the line connecting the outer edge of the tip of one holding part 413 and the outer edge of the proximal end of the other holding part 413 (the fixed end of the holding part 413 and the bottom part 411), and the packaging This corresponds to the angle with the bottom surface of the body 40 (the top surface of the bottom portion 411).

The larger the angle θ ₁ is, the easier it is for the wire 10 to get over the tip of the holding part 413. For this reason, it is desirable that the height Z of the outlet 43 be as large as possible. That is, it is desirable that the outlet 43 be provided at a high position. For this reason, the outlet 43 of this embodiment is arranged at a higher position than the top of the package 40 in the first embodiment (the upper surface of the lid 42 in the first embodiment) (see FIG. 1B).

Furthermore, the larger the angle θ ₁ is compared to the angle θ ₂ , the easier it is for the wire 10 to get over the tip of the holding part 413 . For this reason, it is desirable that the angle θ ₁ is greater than or equal to the angle θ ₂ . As shown in FIG. 4, when the height Z of the outlet 43 is 1.5 times the height Y of the holding part 413, the angle θ ₁ becomes equal to the maximum value of the angle θ ₂ . For this reason, it is desirable that the height Z of the outlet 43 is 1.5 times or more the height Y of the holding part 413.

As shown in FIG. 4, since the wire 10 needs to get over the tip of the holding part 413, it is desirable that the tip of the holding part 413 has a shape that allows the wire 10 to easily get over. For this reason, the holding portion 413 may have a shape that becomes thinner toward the distal end. Further, the tip of the holding portion 413 may be rounded when viewed from the side.

Note that the main body portion 41 does not need to include the holding portion 413. Even when the main body part 41 does not include the holding part 413, if the outlet 43 is provided at a high position, the angle between the center line of the outlet 43 and the wire 10 can be made small, and the wire 10 can be removed from the outlet 43. It becomes easier to pull out. Therefore, even when the main body part 41 does not include the holding part 413, it is advantageous to provide the outlet 43 at a higher position, so that the outlet 43 is higher than the top of the package 40 in the first embodiment. It is desirable to place it in a high position.

The pallet 60 is a member that serves as a stand for the package 40. The pallet 60 serves as a loading platform used when the packaging unit 1 is moved by, for example, a forklift. The pallet 60 may include 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 member disposed between the package 40 (bottom portion 411) and the lower plate portion 61. A gap is formed between the bottom part 411 and the lower plate part 61 by the spacer 62, and a fork of a forklift is inserted into this gap. Note that a gap may be formed on the lower side of the package 40 using only the spacer 62 without providing the lower plate portion 61. The packaging unit 1 does not need to include the pallet 60.

As shown in FIG. 2A, the holding part 413 penetrates the bottom part 411 of the package 40, and the lower end of the holding part 413 is fixed to the lower plate part 61 of the pallet 60. The holding portion 413 is fixed at two locations: the bottom portion 411 of the package 40 and the lower plate portion 61 of the pallet 60. Since the bottom part 411 and the lower plate part 61 have a gap in the vertical direction due to the spacer 62, the holding part 413 is fixed at two places spaced apart in the vertical direction. This provides a structure in which the holding portion 413 does not easily fall down. However, the lower end of the holding part 413 may be fixed to the bottom part 411 of the packing body 40 without the holding part 413 penetrating the bottom part 411 of the packing body 40 .

<Modified example>
5A and 5B are explanatory diagrams of a first modification of the packaging unit 1 of the first embodiment. FIG. 5A is a top view of the packaging unit 1 with the lid 42 open. FIG. 5B is an explanatory diagram of the packaging unit 1 of the second embodiment.
Also in the first modification, the lid 42 has a first lid part 421A and a second lid part 421B, and a recess is provided in the center of the edge of the first lid part 421A and the second lid part 421B. It is being In the first modification, after assembling the first lid part 421A and the second lid part 421B to form the hood part 42A, the first lid part 421A and the second lid part 421B are assembled without attaching the cylinder member 44 to the recess. An outlet 43 is formed by the recess. In this way, the outlet 43 does not need to be composed of the cylindrical member 44.

6A and 6B are explanatory diagrams of a second modification of the packaging unit 1 of the first embodiment.
Also in the second modification, the lid 42 includes a first lid part 421A and a second lid part 421B. In the second modification, coupling portions 422 are provided at the edges of the first lid portion 421A and the second lid portion 421B. The coupling portion 422 is a portion that is coupled to other members when the hood portion 42A is assembled. By coupling the coupling portion 422 of the first lid portion 421A and the coupling portion 422 of the second lid portion 421B, the postures of the first lid portion 421A and the second lid portion 421B are stabilized, and the strength of the hood portion 42A is increased. improves.
Here, the coupling part 422 is configured to have an uneven shape, and the unevenness of the first lid part 421A and the unevenness of the second lid part 421B mesh with each other, so that the first lid part 421A and the second lid part 421B The edges of are joined together. However, the coupling portion 422 is not limited to the uneven shape. For example, one of the connecting parts of the first lid part 421A and the second lid part 421B is made into an insertion piece, the other joining part is made into a slit, and by inserting the insertion piece into the slit, the first lid part 421A and the second lid part 421B The edges of the lid portion 421B may be joined together. However, when the connecting portion 422 is configured to have an uneven shape as shown in FIGS. 6A and 6B, the connecting portion 422 of the first lid portion 421A and the second Since the connecting portion 422 of the lid portion 421B can be combined with the connecting portion 422 of the lid portion 421B, the operation of inserting an insertion piece into a slit is not necessary, so that the assembly work of the hood portion 42A is facilitated.

FIGS. 7A and 7B are explanatory diagrams of a third modification of the packaging unit 1 of the first embodiment.
Also in the third modification, the lid 42 includes a first lid part 421A and a second lid part 421B. Furthermore, in the third modification, the lid 42 has a flap portion 423. The flap portion 423 is a plate-shaped portion that closes the gap in the hood portion 42A. The flap part 423 is provided on the upper edge (upper side) of the side plate part 412 where the first lid part 421A or the second lid part 421B is not provided, and rotates around the upper edge of the side plate part 412 (opens and closes). do). When the gable roof-shaped hood part 42A is assembled with the first lid part 421A and the second lid part 421B, the respective side edges of the first lid part 421A and the second lid part 421B and the side edges of the flap part 423 are concatenated. Thereby, the gap on the side of the gable roof-shaped hood portion 42A can be closed by the flap portion 423. In addition, also in the third modification, like the joint portion 422 of the second modification, the joint is connected to each side edge of the first lid portion 421A and the second lid portion 421B, and to the side edge of the flap portion 423. A connecting portion of the first lid portion 421A or the second lid portion 421B and a connecting portion of the flap portion 423 may be combined by providing a portion. This improves the strength of the hood portion 42A.

FIGS. 8A and 8B are explanatory diagrams of a fourth modification of the packaging unit 1 of the first embodiment.
In the fourth modification, the lid 42 has a plurality of (here, four) lid parts 421. Each lid portion 421 is provided on the upper edge (upper side) of each of the plurality of side plate portions 412 of the main body portion 41 . By connecting the side edges of the four lid parts 421, a rectangular roof-shaped (truncated pyramid-shaped) hood part 42A is assembled. In the fourth modification, the outlet 43 is formed by the edges of the plurality of lid parts 421. Note that the outlet 43 may be configured by the cylindrical member 44 by attaching the cylindrical member 44 to an opening formed by the edges of the plurality of lid parts 421. Since the cylindrical member 44 constitutes the outlet 43, it is possible to prevent the wire 10 from entering between the lid portions 421. In addition, also in the fourth modification, a joining part may be provided on the side edge of each lid part 421, like the joining part 422 of the second modification, and the joining parts of the lid parts 421 may be joined together. This improves the strength of the hood portion 42A.

9A and 9B are explanatory diagrams of a fifth modification of the packaging unit 1 of the first embodiment.
The fifth modification differs from the fourth modification (FIGS. 8A and 8B) in that a recess 424 is formed at the edge of the lid portion 421 constituting the outlet 43. By forming the recess 424 at the edge of the lid portion 421, the recess 424 is arranged at the periphery of the outlet 43. When the wire 10 is pulled out from the outlet 43, the wire 10 enters the recess 424, so that the position of the wire 10 to be pulled out is stabilized at the position of the recess 424. In the fifth modification, the wire rod 10 can be prevented from entering between the lid parts 421 without using the cylindrical member 44.

FIGS. 10A and 10B are explanatory diagrams of a sixth modification of the packaging unit 1 of the first embodiment.
Also in the sixth modification, the lid 42 includes a plurality of (here, four) lid portions 421. Each lid portion 421 has an upper surface portion 425. The upper surface portion 425 is a plate-shaped portion that constitutes the upper surface of the hood portion 42A. The upper surface portion 425 is provided at the edge of the lid portion 421 on the opposite side from the side plate portion 412. A hole 425A is formed in the upper surface portion 425, and the outlet 43 is formed by this hole 425A. Here, each of the four lid sections 421 is provided with an upper surface section 425, and the four upper surface sections 425 are overlapped to form the upper surface of the hood section 42A. However, it is sufficient that at least one lid part 421 is provided with the upper surface part 425. According to the sixth modification, it is possible to prevent the wire 10 from entering between the lid parts 421.

In the first embodiment including the first to sixth modifications described above, the outlet 43 in the second form is located at a higher position than the top of the package 40 in the first form. As a result, the outlet 43 can be placed at a higher position by deforming the packaging unit 1, so that the wire 10 can be easily pulled out with a simple configuration.
Further, in the first embodiment including the first to sixth modifications described above, the package 40 has a plurality of lids 421, and the outlet 43 is connected to the hood 42A assembled by the lids 421. established in As a result, the draw-out port 43 can be provided at a high position using the lid 42, so that the draw-out performance of the wire can be improved without preparing a structure such as an arm.

<Experiment example>
A packaging unit 1 shown in FIGS. 1A and 1B was created, and the performance of pulling out an optical cable (corresponding to the wire 10) was evaluated. Here, packaging units 1 were created in which the distance between the pair of holding parts 413 was 700 mm, the height Y of the holding parts 413 was 720 mm, and the height Z of the outlet 43 was varied in the range of 810 mm to 1500 mm. Note that the diameter of the optical cable is 7 mm. In the evaluation of the pulling performance, if the optical cable could be pulled out from the outlet 43 without pulling the optical cable with excessive force, it was evaluated as good (○), and if the optical cable could be pulled out from the outlet 43 by pulling the optical cable strongly, it was evaluated as good (○). The evaluation was rated as acceptable (△), and the evaluation was rated as unacceptable (x) if the optical cable could not be pulled out.

Table 1 shows the evaluation results of the drawer performance of each packaging unit 1 in which the height Z of the drawer opening 43 is different.

As shown in Table 1, when the height Z of the outlet 43 was 1.5 times or more the height Y of the holding part 413, the optical cable could be pulled out from the outlet 43 without pulling the optical cable with excessive force. Thus, it was confirmed that when the height Z of the outlet 43 is 1.5 times or more the height Y of the holding part 413, the wire 10 easily climbs over the tip of the holding part 413. Note that even in the case of Z/Y=1.46, the optical cable could be pulled out from the outlet 43. In this way, even if the height Z of the outlet 43 is less than 1.5 times the height Y of the holding part 413, if the optical cable can resist being caught on the holding part 413, the optical cable can be removed from the outlet 43. It is possible to extract. However, if the height Z of the outlet 43 is 1.5 times or more the height Y of the holding part 413, the optical cable does not have to resist being caught on the holding part 413, so the height of the outlet 43 It was confirmed that the holding part 413 is easier to pull out compared to the case where Z is less than 1.5 times the height Y of the holding part 413. Note that if the height Z of the outlet 43 is 1.5 times or more the height Y of the holding part 413 as shown in FIG. Also in the case of a packaging unit 1 different from the packaging unit 1 shown in FIG. 1B, the height Z of the drawer opening 43 is equal to the height Y of the holding part 413, similarly to the packaging unit 1 shown in FIGS. 1A and 1B. If it is 1.5 times or more, it will be easier to pull out compared to the case where the height Z of the outlet 43 is less than 1.5 times the height Y of the holding part 413.

===Second embodiment===
FIGS. 11A and 11B are explanatory diagrams of the packaging unit 1 of the second embodiment. FIG. 11A is an explanatory diagram of the packaging unit 1 of the first embodiment. FIG. 11B is an explanatory diagram of the packaging unit 1 of the second embodiment. 12A to 12C are explanatory diagrams of the elevating unit 50. FIG. 12A is a top view of the packaging unit 1. FIG. 12B is an explanatory diagram of the elevating unit 50 in the first embodiment. FIG. 12C is an explanatory diagram of the elevating unit 50 in the second embodiment. Note that in FIGS. 12B and 12C, the side plate portion 412 is not shown in order to show the elevating unit 50 (and the wound body 20).

Also in the second embodiment, the packaging unit 1 includes a rolled body 20, a packaged body 40, and a pallet 60. Note that in the second embodiment as well, the lifting unit 50 does not need to include the pallet 60. The package 40 of the second embodiment further includes a lifting unit 50. Note that the package 40 of the second embodiment may be provided with the lid 42 as in the first embodiment, or may not be provided with the lid 42.

The elevating unit 50 is a member that moves the drawer opening 43 up and down. When the package 40 is in the first form (the form for packing the rolled body 20 into the package 40), the elevating unit 50 is in a state where the drawer opening 43 is lowered and the package 40 (main body part 41) is It is accommodated. In addition, when the packaging body 40 is provided with the lid 42, the lifting unit 50 can be packed in the packaging body 40 by closing the lid 42 (not shown) with the elevating unit 50 lowering the drawer opening 43. When the package 40 is in the second form (the form for drawing out the wire 10), the elevating unit 50 is in a state where the draw-out port 43 is raised, and the draw-out port 43 is located at the top of the package 40 in the first form ( The highest position of the package 40; the upper surface of the lid 42 if there is one; the upper edge of the main body 41 if there is no lid 42). Note that when the package 40 includes a lid 42, when transforming the package 40 from the first form to the second form, the lid 42 is opened and then the drawer opening 43 is opened using the lifting unit 50. It will be placed in a higher position.

The elevating unit 50 includes a moving body 51 having an outlet 43 and a telescopic member 52.

The moving body 51 is a member that moves (elevates and lowers) in the vertical direction. When the packing body 40 is in the first form (a form for packing the wire rod 10), the movable body 51 is in the lowered position and is packed in the main body part 41. When the package 40 is in the second form (the form for pulling out the wire 10), the movable body 51 is in an elevated position, higher than the top of the package 40 in the first form. The moving body 51 has an outlet 43 and a connecting portion 511. In the second embodiment, the outlet 43 is not provided in the lid 42 of the package 40 but is provided in the movable body 51. The connecting portion 511 is a portion that connects the outlet 43 and the elastic member 52. One end of the connecting portion 511 is connected to the outlet 43, and the other end of the connecting portion 511 is connected to the expandable member 52 (specifically, the tip of the expandable member 52). The outlet 43 and the connecting portion 511 shown in FIGS. 12A to 12C are made of the same member (rod-shaped member). However, the member constituting the outlet 43 and the member constituting the connecting portion 511 may be configured as separate members (described later; see FIG. 14C).

As shown in FIG. 11A, when the package 40 is in the first form (a form for packing the wire 10), the movable body 51 is arranged below the tip of the holding part 413. Thereby, it is possible to suppress the wire rod 10 of the wound body 20 from coming off from the holding part 413 in the first embodiment. However, in the first form, the movable body 51 may be arranged above the holding part 413 (but below the top of the package 40 in the first form).
Further, as shown in FIG. 11A, when the packing body 40 is in the first form (a form for packing the wire rod 10), the movable body 51 is in contact with the upper surface of the wound body 20 (the form for packing the wire rod 10). (in contact with the wire 10 forming the upper surface). Thereby, the wire rod 10 of the wound body 20 can be suppressed in the first form, and the collapse of the wound body 20 can be suppressed. However, even if the movable body 51 is not in contact with the wire rod 10 of the wound body 20, if the movable body 51 is arranged below the tip of the holding part 413, the wire rod 10 of the wound body 20 is connected to the holding part. It is possible to suppress deviation from 413.

The expandable member 52 is a member that expands and contracts in the vertical direction. The extensible member 52 is a member that moves the movable body 51 in the vertical direction (elevates and lowers). The expandable member 52 is a member extending in the vertical direction, and extends upward from the bottom portion 411. The lower end of the telescopic member 52 in the figure is fixed to the bottom portion 411. However, similarly to the holding part 413 described above, the expandable member 52 may penetrate through the bottom 411 of the package 40 and be fixed at two locations, the bottom 411 and the lower plate 61 of the pallet 60. This provides a structure in which the expandable member 52 is difficult to fall down. A movable body 51 (specifically, a connecting portion 511) is fixed to the upper end of the expandable member 52. As the extensible member 52 expands and contracts, the movable body 51 moves in the vertical direction (elevates and descends). The plurality of elastic members 52 are arranged on the outside of the wound body 20, and are arranged at intervals in the circumferential direction so as to surround the wound body 20. Here, four elastic members 52 are arranged at 90 degree intervals around the outer circumference of the wound body 20.

FIG. 13 is an explanatory diagram of an example of the structure of the expandable member 52.

The expandable 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 vertical direction. When the upper member 521 slides upward with respect to the lower member 522, the expandable member 52 expands. Note that instead of sliding the upper member 521 and the lower member 522, the upper member 521 and the lower member 522 are joined by a hinge, and the angle of the hinge is widened (in other words, the upper member 521 and the lower member 522 are in a folded state. The telescoping member 52 may be extended (by deploying the lower member 522). The extensible member 52 may be expandable and retractable in multiple stages by having multiple stages of the structure shown in FIG. Here, the upper member 521 and the lower member 522 are configured in a cylindrical shape, the outer diameter of the upper member 521 is smaller than the inner diameter of the lower member 522, and the upper member 521 is arranged inside the lower member 522. . The fixing portion 523 fixes the upper member 521 and the lower member 522, and fixes the expandable member 52 in an expanded state. The fixing portion 523 in the figure is provided on the upper member 521 and has a protrusion that is biased outward by a spring. When the upper member 521 moves upward with respect to the lower member 522, the protrusion of the fixing portion 523 enters the fitting hole of the lower member 522, thereby fixing the upper member 521 and the lower member 522. In this way, the fixing part 523 is preferably configured to automatically fix the upper member 521 and the lower member 522 when the upper member 521 is moved to a predetermined position relative to the lower member 522. This makes it easier to fix the telescopic member 52 in an extended state, compared to, for example, fixing the upper member 521 and the lower member 522 with screws. In particular, when it is necessary to simultaneously extend a plurality of telescopic members 52 when raising the movable body 51 (drawer port 43), the fixing section 523 is configured to automatically fix the upper member 521 and the lower member 522. If so, the work of fixing the movable body 51 (drawing port 43) in the raised state becomes easy.

Note that the fixing portion 523 is not limited to the structure shown in FIG. 13. For example, the fixing part is provided on the lower member 522 and has a protrusion that is biased inward, and the protrusion of the fixing part enters the fitting hole of the upper member 521, thereby causing the upper member 521 and the lower member to 522 may be fixed. Further, the fixing portion 523 is not limited to the structure in which the protrusion is biased by a spring as shown in FIG. 13. For example, by providing a taper on the outer surface of the upper member 521 and the inner surface of the lower member 522 and moving the upper member 521 upward with respect to the lower member 522, the outer surface of the upper member 521 and the inner surface of the lower member 522 are fitted together. The expandable member 52 may be fixed in an expanded state. Even with this configuration in which the tapered surfaces are fitted together, it is possible to automatically fix the upper member 521 and the lower member 522 when the upper member 521 is moved to a predetermined position relative to the lower member 522. It is possible. However, the fixing portion 523 is not limited to a structure that automatically fixes the upper member 521 and the lower member 522, and may fix the upper member 521 and the lower member 522 using, for example, screws, pins, bolts, or the like. Further, the upper member 521 and the lower member 522 are not limited to cylindrical members, and may be formed of, for example, rod-shaped or plate-shaped members. Moreover, the fixing part 523 does not need to be provided in the elevating unit 50 itself. However, if the elevating unit 50 includes the fixing part 523, the work of fixing the expandable member 52 in the extended state becomes easier.

14A to 14C are explanatory diagrams of modified examples of the elevating unit 50.

The elevating unit 50 of the first modified example shown in FIG. 14A has a moving body 51 and a telescopic member 52. It is located. The moving body 51 has two intersecting bridge parts 512. The bridging portion 512 is a portion that bridges the distal ends of the two opposing elastic members 52. Each bridge portion 512 is composed of a pair of parallel rod members. A portion where the two bridge portions 512 intersect constitutes the outlet 43, and the other portion constitutes the connecting portion 511.

Also in the second modification shown in FIG. 14B, the elevating unit 50 includes a moving body 51 and an elastic member 52. In the second modification, the elevating unit 50 has two telescopic members 52, and a bridge portion 512 is provided so as to bridge the tips of the two telescopic members 52. In the second modification, the outlet 43 is configured in the center of the bridge portion 512, and the connecting portion 511 is configured by the other portions. As shown in the second modification, the elastic members 52 do not need to be arranged at 90 degree intervals around the outer circumference of the wound body 20.

Also in the third modification shown in FIG. 14C, the elevating unit 50 includes a moving body 51 and a telescopic member 52. The moving body 51 of the third modification includes an outlet 43 formed of an annular member 513, and a string member (corresponding to the connecting portion 511) that connects the outlet 43 (annular member 513) and the elastic member 52. has. In this way, the outlet 43 and the connecting portion 511 do not need to be made of rod-shaped members.

In the second embodiment including the first to third variations described above, similarly to the first embodiment, the outlet 43 in the second embodiment is located at a higher position than the top of the package 40 in the first embodiment. . As a result, the draw-out port 43 can be placed at a higher position by deforming the packaging unit 1, so that the ease of drawing out the wire can be improved without preparing a structure such as an arm.
Further, in the second embodiment including the first to third modifications described above, unlike the first embodiment, the package 40 includes a moving body 51 having an outlet 43 and an elastic member 52. . Thereby, by extending the elastic member 52, the outlet 43 can be placed at a higher position. In addition, since the elevating unit 50 is packed in the packing body 40, when drawing out the wire rod 10, there is no need for a drawing device or the like which is configured separately from the packing unit 1.
Note that also in the second embodiment including the first to third variations described above, as shown in FIG. 4, it is desirable that the angle θ ₁ is equal to or greater than the angle θ ₂ . Therefore, in the second embodiment including the first to third modifications described above, the height Z of the outlet 43 is 1.5 times the height Y of the holding part 413, as in the first embodiment. The above is desirable.
