[0014] [Reel] As shown in FIG. 1, the reel 10 includes a reeling drum 1 and two flanges 2 (flange plates) provided on one end and the other end of the reeling drum 1, respectively. The winding drum 1 is formed in a cylindrical shape and can be wound with a wire 100 (see FIG. 6) such as an electric wire or cable.

[0015] The structure of the reel 10 will be described using an XYZ Cartesian coordinate system. The Z direction is the direction (axial direction) along the central axis of the reel drum 1. The X direction is the length direction of the veneer material 5. The X direction is perpendicular to the Z direction. The Y direction is the width direction of the veneer material 5. The Y direction is perpendicular to the Z direction and the X direction. The X direction is perpendicular to the Y direction. The plane along the X direction and the Y direction is the XY plane. The plane along the Y direction and the Z direction is the YZ plane. The circumferential direction is the direction going around the central axis of the reel drum 1.

[0016] Based on Figure 5, the positional relationship of each component in flange portion 2 will be provisionally defined. One side of the X direction (the right side in Figure 5) is the +X side. The side opposite the +X side is the -X side. The Y direction is the up-and-down direction. One side of the Y direction (the upper side in Figure 5) is the +Y side. The side opposite the +Y side is the -Y side. The positional relationship defined here does not limit the orientation of reel 10 during use.

[0017] A view from the Z direction is called a plan view. The "inner axial direction" is the direction in which the two flanges 2 approach each other. The "outer axial direction" is the direction opposite to the inner axial direction. The radial direction is the direction passing through the central axis of the hoisting drum 1 in a plane perpendicular to the central axis of the hoisting drum 1.

[0018] 1 and 3, the flange portion 2 is a disk-shaped member concentric with the winding drum portion 1. The outer diameter of the flange portion 2 is larger than the outer diameter of the winding drum portion 1. The flange portion 2 protrudes radially outward from the outer peripheral surface 1a at the end of the winding drum portion 1.

[0019] As shown in FIGS. 1 to 4, the flange 2 includes a flange main body 3 and a plurality of reinforcing members 4. As shown in FIGS. The flange body 3 is a composite plate having a plurality of veneer materials 5. The veneer materials 5 are in the form of long plates. The plurality of veneer materials 5 are arranged side by side with their sides facing each other and no gaps in the width direction. The plurality of veneer materials 5 are arranged adjacent to each other. The outer surface 3a of the flange body 3 is the outer surface in the axial direction. The veneer materials 5 are formed, for example, from wood.

[0020] An outlet hole 6 is formed in the flange body 3. The outlet hole 6 is a hole for pulling out the end (winding start end) of the wire wound around the winding drum 1 to the outside of the flange 2. The outlet hole 6 penetrates the flange body 3 (single plate material 5) in the thickness direction. The outlet hole 6 is an arc-shaped slit that runs along the circumferential direction of the flange body 3. The outlet hole 6 is formed radially outward from the outer peripheral surface 1a of the winding drum 1 in a plan view. The outlet hole 6 is formed at a position close to the outer peripheral surface 1a of the winding drum 1 in a plan view.

[0021] As shown in Figures 1 and 3, a plurality of mounting recesses 7 are formed on the outer surface 3a of the flange main body 3. The mounting recesses 7 are formed in the shape of grooves. The plurality of mounting recesses 7 include first to fifth mounting recesses 7A to 7E. The first to fourth mounting recesses 7A to 7D are formed along the Y direction (a direction intersecting with the X direction).

[0022] The first to fourth mounting recesses 7A to 7D are formed across a plurality of veneer materials 5 aligned in the Y direction. The first mounting recess 7A and the second mounting recess 7B are formed across all of the veneer materials 5. The first to fourth mounting recesses 7A to 7D are parallel to one another. The first to fourth mounting recesses 7A to 7D are formed at intervals in the X direction.

[0023] As shown in FIGS. 2 and 4, the shape of the cross section perpendicular to the longitudinal direction of the mounting recess 7 is, for example, rectangular.

[0024] As shown in Figures 1 and 3, the first mounting recess 7A is formed on the -X side of the center of the outer surface 3a. The second mounting recess 7B is formed on the +X side of the center of the outer surface 3a. The first mounting recess 7A and the second mounting recess 7B face each other in the X direction. The first mounting recess 7A and the second mounting recess 7B are formed with a gap between them in the X direction. The upper and lower ends of the mounting recesses 7A and 7B reach the periphery (upper edge) of the outer surface 3a. The first mounting recess 7A and the second mounting recess 7B have the same length.

[0025] In plan view, the first mounting recess 7A is formed on the -X side from the -X side end of the lead-out hole 6. In plan view, the second mounting recess 7B is formed on the +X side from the +X side end of the lead-out hole 6.

[0026] The third mounting recess 7C is formed at a position on the -X side of the first mounting recess 7A. The third mounting recess 7C faces the first mounting recess 7A. The third mounting recess 7C is formed at a distance from the first mounting recess 7A. The fourth mounting recess 7D is formed at a position on the +X side of the second mounting recess 7B. The fourth mounting recess 7D faces the second mounting recess 7B. The fourth mounting recess 7D is formed at a distance from the second mounting recess 7B. The upper and lower ends of the mounting recesses 7C and 7D reach the peripheral edge of the outer surface 3a. The third mounting recess 7C and the fourth mounting recess 7D have the same length.

[0027] The fifth mounting recess 7E is formed from the inner edge of the first mounting recess 7A to the inner edge of the second mounting recess 7B. The fifth mounting recess 7E is formed along the X direction at a position below the center of the outer surface 3a. The fifth mounting recess 7E is formed at a position lower than the lead-out hole 6. The fifth mounting recess 7E is formed at a position radially outward from the lead-out hole 6. The fifth mounting recess 7E is formed in the vicinity of the lead-out hole 6.

[0028] The multiple reinforcing members 4 include first to fifth reinforcing members 4A to 4E. Of the first to fifth reinforcing members 4A to 4E, the first to fourth reinforcing members 4A to 4D are main reinforcing members 4A to 4D (first to fourth main reinforcing members 4A to 4D). The fifth reinforcing member 4E is an auxiliary reinforcing member 4E.

[0029] The first to fifth reinforcing members 4A to 4E are formed in a rod shape and are made of, for example, wood.

[0030] The first to fifth reinforcing members 4A to 4E fit into the first to fifth mounting recesses 7A to 7E, respectively. Portions of the first to fifth reinforcing members 4A to 4E enter and fit into the first to fifth mounting recesses 7A to 7E, respectively.

[0031] 2 and 6, the shape of the cross section of the reinforcing member 4 perpendicular to the longitudinal direction is, for example, rectangular. The dimension of the reinforcing member 4 in the Z direction (the dimension in the depth direction of the mounting recess 7) is, for example, greater than the depth of the mounting recess 7. Therefore, a portion of the reinforcing member 4 protrudes outward in the axial direction from the outer surface 3a.

[0032] The widths of the first to fifth reinforcing members 4A to 4E are approximately the same as or slightly smaller than the widths of the first to fifth mounting recesses 7A to 7E, respectively. As long as the first to fifth reinforcing members 4A to 4E can fit into the first to fifth mounting recesses 7A to 7E, respectively, the widths of the first to fifth reinforcing members 4A to 4E may be larger than the widths of the first to fifth mounting recesses 7A to 7E. It is desirable that portions of the first to fifth reinforcing members 4A to 4E are press-fitted into the first to fifth mounting recesses 7A to 7E and fixed by friction to the inner surfaces of the first to fifth mounting recesses 7A to 7E.

[0033] As shown in Figures 1 and 3, the first to fourth main reinforcing members 4A to 4D are formed along the Y direction (a direction intersecting the X direction). The first to fourth main reinforcing members 4A to 4D are formed across a plurality of veneer materials 5. The first main reinforcing member 4A and the second main reinforcing member 4B are formed across all of the veneer materials 5. The first to fourth main reinforcing members 4A to 4D are parallel to one another. The first to fourth main reinforcing members 4A to 4D are formed at intervals in the X direction.

[0034] The first main reinforcement 4A is formed on the -X side of the center of the outer surface 3a. The second main reinforcement 4B is formed on the +X side of the center of the outer surface 3a. The first main reinforcement 4A and the second main reinforcement 4B face each other in the X direction. The upper ends of the main reinforcements 4A and 4B are located close to the periphery (upper edge) of the outer surface 3a. The lower ends of the main reinforcements 4A and 4B are located close to the periphery (lower edge) of the outer surface 3a. The first main reinforcement 4A and the second main reinforcement 4B have the same length.

[0035] In plan view, the first main reinforcing member 4A is formed on the -X side of the -X side end of the outlet hole 6. In plan view, the second main reinforcing member 4B is formed on the +X side of the +X side end of the outlet hole 6.

[0036] The third main reinforcement 4C is formed on the -X side of the first main reinforcement 4A. The third main reinforcement 4C faces the first main reinforcement 4A. The fourth main reinforcement 4D is formed on the +X side of the second main reinforcement 4B. The fourth main reinforcement 4D faces the second main reinforcement 4B. The upper and lower ends of the main reinforcements 4C and 4D are located near the periphery of the outer surface 3a. The third main reinforcement 4C and the fourth main reinforcement 4D have the same length.

[0037] The auxiliary reinforcement 4E is formed from the inner edge of the first main reinforcement 4A to the inner edge of the second main reinforcement 4B. It is desirable that the auxiliary reinforcement 4E bridges between the first main reinforcement 4A and the second main reinforcement 4B. The auxiliary reinforcement 4E is provided below the center of the outer surface 3a along the X direction. The auxiliary reinforcement 4E is formed at a position lower than the outlet hole 6. The auxiliary reinforcement 4E is formed in the vicinity of the outlet hole 6.

[0038] As shown in FIGS. 5 and 7, the flange body 3 and the reinforcing member 4 are connected by a plurality of connecting members 8. As shown in Fig. 7, the connecting member 8 is in the form of a long plate (e.g., a rectangle) with its longitudinal direction along the Y direction. The connecting member 8 is in the form of a plate parallel to the YZ plane. The connecting member 8 is formed thinner than the width (dimension in the X direction) of the reinforcing member 4. The connecting member 8 is formed, for example, from wood.

[0039] A slit-shaped first fitting recess 11 extending along the Y direction is formed on the inner surface 7a (bottom surface) of the mounting recess 7. The first fitting recess 11 is formed penetrating through the flange main body 3 in the thickness direction (Z direction). A slit-shaped second fitting recess 12 extending along the Y direction is formed on the side surface 4a of the reinforcing member 4 (the surface facing the inner surface 7a).

[0040] 8 and 9, a first portion 8A (an inner portion in the axial direction) that is a part of the connecting member 8 enters into the first fitting recess 11 and fits into the first fitting recess 11. The fitting between the first portion 8A and the first fitting recess 11 can be said to be a concave-convex fitting, because the first portion 8A, which is a convex portion, enters into the first fitting recess 11.

[0041] The thickness of the first portion 8A is approximately the same as or slightly smaller than the width of the first fitting recess 11. As long as the first portion 8A can be fitted into the first fitting recess 11, the thickness of the first portion 8A may be greater than the width of the first fitting recess 11. It is desirable that the first portion 8A be press-fitted into the first fitting recess 11 and fixed to the inner surface of the first fitting recess 11 by friction.

[0042] The second portion 8B (axial outer portion), which is another part of the connecting member 8, enters into the second fitting recess 12 and fits into the second fitting recess 12. The fitting between the second portion 8B and the second fitting recess 12 can be said to be a convex-concave fitting, because the second portion 8B, which is a convex portion, enters into the second fitting recess 12.

[0043] The thickness of the second portion 8B is approximately the same as or slightly smaller than the width of the second fitting recess 12. As long as the second portion 8B can be fitted into the second fitting recess 12, the thickness of the second portion 8B may be greater than the width of the second fitting recess 12. It is desirable that the second portion 8B be press-fitted into the second fitting recess 12 and fixed to the inner surface of the second fitting recess 12 by friction.

[0044] The connecting member 8 can be installed by inserting it into the first fitting recess 11 and the second fitting recess 12 from the inner surface side of the flange body 3. The first portion 8A of the connecting member 8 fits into the first fitting recess 11, and the second portion 8B of the connecting member 8 fits into the second fitting recess 12, thereby connecting the flange body 3 and the reinforcing member 4 via the connecting member 8.

[0045] 5, the reinforcing member 4 is connected to the flange main body 3 by a plurality of connecting members 8. The plurality of connecting members 8 are provided at different positions in the length direction of the reinforcing member 4.

[0046] [Effects of the Winding Frame of the Embodiment] As shown in FIGS. 1 and 2, in the reinforcing frame 10, the reinforcing member 4 fits into the mounting recess 7 of the flange body 3. This restricts relative movement between the reinforcing member 4 and the flange body 3 (for example, movement in a direction along the XY plane). This increases the mechanical strength of the flange 2. Of the reinforcing members 4, the main reinforcing members 4A to 4D extend across multiple veneer materials 5. This allows the main reinforcing members 4A to 4D to determine the relative positions of the multiple veneer materials 5. This further increases the mechanical strength of the flange 2.

[0047] In the reel 10, the reinforcing material 4 can provide sufficient strength to the flange 2, allowing the thickness of the flange main body 3 to be reduced. Therefore, the weight of the flange 2 of the reel 10 can be reduced compared to a reel having a flange made of multiple laminated composite plates. This allows the reel 10 to be made lighter. This reduces the burden of material handling in the manufacture of wire rod. The burden of transporting the reel 10 can also be reduced, allowing for savings in fuel costs required for transportation.

[0048] In the reel 10, the thickness of the flange main body 3 can be reduced, and therefore the material cost of the flange 2 can be reduced.

[0049] As shown in FIG. 7, in the reel 10, the flange main body 3 and the reinforcing member 4 are connected by a connecting member 8 that fits into the fitting recesses 11 and 12. This allows the reinforcing member 4 to be firmly connected to the flange main body 3. By using the connecting member 8, the reinforcing member 4 and the flange main body 3 can be connected without using metal fittings such as nails. This makes it easy to assemble and disassemble the reel 10. When disassembling, this reduces the effort required to separate the wood from the metal fittings. This reduces the time required to assemble and disassemble the reel 10.

[0050] In the reel 10, the auxiliary reinforcing member 4E is bridged between the first main reinforcing member 4A and the second main reinforcing member 4B, so that the reinforcing effect of the reinforcing member 4 can be enhanced.

[0051] In the reel 10, the auxiliary reinforcing material 4E is provided near the outlet hole 6, thereby reinforcing the flange main body 3 in the area where the outlet hole 6 is formed, thereby increasing the mechanical strength of the flange main body 3.

[0052] The flange 2 is mostly made of wood. Wood emits less CO2 during production than other materials (for example, steel), making the reel 10 suitable from the standpoint of environmental conservation.

[0053] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. 1, the flange portion 2 is provided with a plurality of reinforcing members 4, but the number of reinforcing members is not particularly limited. The number of reinforcing members can be one or more. In the reel 10, a plurality of mounting recesses 7 are formed in the flange body 3, but the number of mounting recesses is not particularly limited. The number of mounting recesses may be one or more.

[0054] 2 and 4, in the reel 10, the cross section perpendicular to the longitudinal direction of the reinforcing material 4 has a rectangular shape, but the cross-sectional shape of the reinforcing material is not particularly limited. The cross-sectional shape of the reinforcing material may be a circle or a polygon such as a triangle or pentagon.

[0055] As shown in FIG. 2, in the reinforcing member 10, the reinforcing member 4 protrudes outward in the axial direction from the outer surface 3a of the flange body 3, but the reinforcing member does not have to protrude from the outer surface 3a of the flange body 3. 1 uses both main reinforcing members 4A to 4D and auxiliary reinforcing member 4E, but the reinforcing member may be the main reinforcing member alone. Although four main reinforcing members 4A to 4D are used in reinforcing member 10, the number of main reinforcing members may be at least one. The number of auxiliary reinforcing members may be one or more (any number equal to or greater than two).

[0056] 5, in the reinforcing member 10, the reinforcing member 4 is connected to the flange main body 3 by a plurality of connecting members 8, but the number of connecting members per reinforcing member is not particularly limited. The number of connecting members per reinforcing member may be one or more. In the reel 10 shown in Figures 1 and 2, the flange body 3 is made of one composite plate material, but the flange body 3 may also be made of a plurality of laminated composite plate materials.

[0057] 1, the main reinforcing members 4A-4D and the mounting recesses 7A-7D are formed along the Y direction, but the extending direction of the main reinforcing members and the mounting recesses may be any direction that intersects with the longitudinal direction of the veneer in a plan view. For example, the main reinforcing members and the mounting recesses may be inclined at an angle greater than 0° and less than 90° with respect to the longitudinal direction of the veneer in a plan view.

[0058] 1 includes a winding drum 1 and flanges 2 provided at both ends of the winding drum 1, but the flanges may be provided only at one end of the winding drum. The flanges are not limited to being provided at the ends of the winding drum, and may be provided at any position along the length of the winding drum.

[0059] In addition, it is possible to replace the components in the above-described embodiments with well-known components as appropriate, and the above-described embodiments and variations may be combined as appropriate, without departing from the spirit of the present invention.
