Description

  The present invention relates to a bobbin for winding a long object and a winding hose in which a hose is wound around the bobbin, and more particularly to a bobbin and a winding hose suitable for reuse.

For example, a long object such as a hose used for industrial, agricultural, or general households is often wound around a bobbin and displayed at a store, and only the sales amount is drawn from the bobbin and cut and sold. In general, long objects are wound around a bobbin from a factory before being shipped, and the bobbin is generally discarded after being sold at a store. Bobbins are often made of plastic, and disposal is not preferable from the viewpoint of effective use of resources and from the viewpoint of environment. However, returning only the bobbin was not economical in terms of transportation costs. Therefore, in order to facilitate the return of the used bobbin, for example, a method of detachably attaching the flange portion of the bobbin has been studied. (See Patent Document 1)
JP 2003-182939 A (pages 2 and 3, FIG. 1)

  However, even if the flange is detachable, it is necessary to discard the core around which the long object is wound, or it is necessary to return the core, which does not completely solve the above problem. Therefore, the present invention provides a bobbin capable of easily attaching a long object wound without having a winding core to a bobbin, and also providing a winding hose in which a hose is wound around the bobbin. With the goal.

  In order to achieve the above object, the bobbin according to the first aspect of the present invention includes, for example, as shown in FIG. 1, cylindrical cores 20a and 20b around which a long object is wound; both ends of the cores 20a and 20b Two flanges 10a, 10b arranged on the side; the cores 20a, 20b are divided into at least two by a surface 23 angled with a cylindrical axis. Here, “a plane having an angle with respect to the cylindrical axis” means a plane that is not a plane perpendicular to the cylindrical axis and is not a plane parallel to the cylindrical axis, and is not necessarily flat. And may include only a portion of the surface that is perpendicular or parallel to the cylindrical axis.

  With this configuration, since the core is divided by a surface having an angle with respect to the cylindrical shaft, a large cross section side and a small cross section side are formed on the divided core, and one split core is formed. Is inserted into the space inside the long object wound without having a core, and the other divided core is inserted into the space inside the long object wound from the small cross-section side. It becomes easy to insert the winding core into the space inside the wound long object. In addition, since the divided core is easy to insert into the space inside the long object wound from the small cross-section side, even if the outer diameter of the core is slightly larger than the inner dimension of the wound long object A core can be inserted and a long thing and a core can be stuck.

  In the bobbin according to the invention described in claim 2, for example, as shown in FIG. 1, in the bobbin 1 described in claim 1, the winding cores 20a, 20b may be cylindrical.

  If comprised in this way, since a core is cylindrical, it is easy to wind a long thing around a core, and does not damage a long thing with the corner of a core, etc.

  Further, in the bobbin according to claim 3, for example, as shown in FIG. 1, in the bobbin 1 according to claim 1 or 2, the flanges 10a and 10b may be detachable from the cores 20a and 20b. .

  If comprised in this way, a flange and a core can be shape | molded separately. Therefore, the width of the bobbin can be easily changed by changing the length of the core.

  Moreover, in the bobbin according to claim 4, as shown in FIGS. 1 and 2, for example, in the bobbin 1 according to claim 3, the flange 12 is inserted into the cylindrical inside of the winding cores 20a and 20b. The protrusion 14 may be integrally formed.

  If comprised in this way, since the protrusion of a flange will be inserted inside the cylindrical shape of a core, it will become easy to adhere a flange and a core.

  Moreover, in the bobbin which concerns on invention of Claim 5, in the bobbin 1 of Claim 3 or Claim 4, for example, as shown in FIGS. 1-3, the attachment hole 16 is provided in flange 10a, 10b (10). The two flanges 10 a and 10 b may be integrated by forming the dowels 27 into the mounting holes 16.

  If comprised in this way, since two flanges are integrated by inserting a dowel into an attachment hole, it becomes easy to assemble and disassemble a bobbin from a flange and a core.

  Further, in the bobbin according to the invention described in claim 6, as shown in FIGS. 2 and 3, for example, in the bobbin according to claim 5, the support surface 26 is formed inside the winding core 20, and the support surface 26. The dowels 27 may be fixed to.

  If comprised in this way, since the dowel fixed to the core is inserted in the attachment hole of a flange, and a flange and a core are integrated, a flange and a core are easy to adhere, and a flange and a core are also included. The bobbin can be easily assembled and disassembled.

  In the bobbin according to the invention described in claim 7, for example, as shown in FIG. 5, in the bobbin 2 described in claim 3 or 4, the dowel 36 is fixed to the flange 30; the cores 40a, 40b A support surface 46 is formed on the inside of the support surface 46, and a hole 47 is formed in the support surface 46; the dowel 36 may be fitted into a hole 47 formed in the support surface 46.

  With this configuration, the dowels fixed to the flange are fitted into the holes formed in the support surface of the core to integrate the flange and the core, so that the flange and the core are easily fixed. The bobbin can be easily assembled and disassembled from the flange and the winding core. Furthermore, since the support surface receives a force from the dowel through the hole, the moment acting on the support surface is reduced, and the support surface can be made thin.

  Further, as shown in FIG. 11, for example, the bobbin according to the eighth aspect of the present invention is the bobbin 9 according to the fourth aspect, wherein the divided core 180b is closed to fit around the protrusion 14 of the flange 170b. The closed portion 182 is combined with a divided core 180a different from the divided core 180b having the closed portion 182, so that the closed portion 182 is not displaced in the direction perpendicular to the axis. May be configured.

  With this configuration, the closed portion of the divided core fits around the protrusion of the flange, and the closed portion is combined with another divided core so that it does not shift in the direction perpendicular to the axis. Thus, the bobbin is stably assembled without causing the winding core to shift.

  Further, in the bobbin according to the invention described in claim 9, for example, as shown in FIG. 11, in the bobbin 9 described in claim 8, the cover portion overlapping the divided cores 180a to be combined with the closed portion 182 183 may be provided.

  If comprised in this way, since the closed part is provided with the cover part which overlaps with the divided | segmented winding core combined, the divided | segmented winding core will not be shifted | deviated perpendicularly to an axis | shaft reliably.

  Further, the bobbin according to the invention described in claim 10 is, for example, as shown in FIG. 11, in the bobbin 9 according to claim 8 or 9, the fastening member 172 that passes through and fastens the two flanges 170 a, 170 b. -174 is provided.

  If comprised in this way, since a flange will be fastened by a fastening member, it will not shift | deviate to an axial direction and an assembled bobbin will not break.

  Further, in the bobbin according to the invention described in claim 11, for example, as shown in FIG. 1, in the bobbin 1 described in any one of claims 1 to 10, the winding cores 20 a and 20 b are divided into two. The cores 20a and 20b divided into two are the same shape; the two flanges 10a and 10b may be the same shape.

  If comprised in this way, the number of parts for manufacturing a bobbin can be reduced, manufacture becomes easy and it is economical. In particular, when the flange and the core are made of resin and are manufactured by molding with a mold, the number of molds can be reduced, which is economically advantageous.

  In order to achieve the object, a winding hose according to a twelfth aspect of the present invention includes a bobbin 1 according to any one of the first to eleventh aspects, as shown in FIG. And a hose 152 wound around.

  If comprised in this way, it will become a winding hose which attached the bobbin to the hose shipped without winding around a core. Therefore, the bobbin can be reused, and the bobbin or a part of the bobbin can be discarded or returned to the factory.

  According to the present invention, the bobbin includes a cylindrical winding core on which a long object is wound, and two flanges disposed on both ends of the winding core, and the winding core has an angle with respect to the cylindrical shaft. Since the surface is divided into at least two parts, the core can be easily inserted into the space inside the wound long object. Moreover, since a winding hose is provided with said bobbin and the hose wound around the bobbin, it becomes a winding hose which attached the bobbin to the hose shipped without being wound around the core. Therefore, the bobbin can be reused, and the bobbin or a part of the bobbin can be discarded or returned to the factory.

  Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same or corresponding devices are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 is a diagram illustrating a bobbin as a first embodiment of the present invention. 1A is a perspective view of the assembled bobbin 1, and FIG. 1B is an exploded perspective view of the bobbin 1. The bobbin 1 includes flange members 10a and 10b and core members 20a and 20b. Here, since the two flange members 10a and 10b have the same shape and the two core members 20a and 20b have the same shape, they may be collectively referred to as the flange member 10 and the core member 20. Similarly, in the bobbin described later, the flange member and the core member are described with a and b added to distinguish the two elements, and collectively described without a and b. There are cases. The flange member 10 and the core member 20 are typically made of plastic because they are lightweight and easy to mold.

  FIG. 2 is an explanatory diagram of the flange member 10. 2A is a front view, and FIG. 2B is a cross-sectional view. The flange member 10 includes a hollow disc-shaped flange 12 and a cylindrical projection 14 that protrudes from the hollow portion of the flange 12 in the plate thickness direction of the flange 12 and has a flat surface 15 at the protruding portion. The flange 12 is a member for preventing a long object (not shown) wound around the bobbin 1 from collapsing, and is not limited to a hollow disk shape, but a polygonal plate such as a rectangular plate or a hexagonal plate. In addition, holes or gaps may be formed between the plates, or may be formed by rods arranged radially from the protrusions 14. When the flange 12 is a hollow disk, for example, when it is displayed at a store or the like, when the bobbin 1 in which a long object is wound up with two bars arranged in parallel is placed on a fixture for display, It is easy to pull out long objects. On the other hand, if the flange 12 is formed of a polygonal or radial rod (both not shown), it is difficult to roll and easy to handle when the bobbin is placed on the ground. Further, if holes or gaps are formed between the plates of the flange 12, or if the flange 12 is formed by a radially arranged rod, the material used for the flange can be saved, and resource saving and weight reduction can be achieved. Can contribute.

  The protrusion 14 protrudes in a cylindrical shape from the hollow periphery of the flange 12 in the plate thickness direction of the flange 12, and a flat surface 15 is formed at the protruding end. A through hole 18 is formed in the center of the plane 15. The through hole 18 is used to prevent the bobbin 1 from moving by suspending the bobbin 1 with a thin metal rod, wire or string, or by inserting it into a vertically standing rod. It may not be formed. Further, the flat surface 15 is formed with an attachment hole 16 for fitting a dowel of the core member 20 described later and fixing the dowel to the core member 20. Although three attachment holes 16 are formed in the flange member 10, the number of attachment holes 16 is not limited to three. The larger the number of mounting holes 16, the more firmly fixed to the core member 20. However, when the number is small, the structure is simple and easy to manufacture, and the flange member 10 and the core member 20 can be attached and detached. It becomes easy.

  FIG. 3 is an explanatory diagram of the core member 20. 3, (a) is a front view from the large diameter 24 side of the core member 20, (b) is a side view of the core member 20, and (c) is a rear view from the small diameter 25 side of the core member 20. Indicates. Two core members 20 are combined to form a core. That is, two core members 20 are formed by dividing a core having a cylindrical outer shape by a surface 23 having an angle with respect to a cylindrical axis. Since the core has an angle with respect to the cylindrical axis and is divided by the surface 23 reaching the end surface, the core member 20 is formed, so that the core member 20 is more than half of the cylindrical circular cross section. It has a large-diameter side end surface 24 including a portion and a small-diameter side end surface 25 of a portion less than half. The left side of FIG. 3B is the large diameter side end face 24, and the right side is the small diameter side end face 25.

  The core member 20 includes a core body 22 having a shape obtained by dividing a cylindrical shape, and a semicircular support surface 26 disposed at the center of the cylindrical member in the axial direction of the cylindrical shape. The support surface 26 may be formed integrally with the core body 22 or may be fixed to the core body 22 after being formed as a separate body. The inner diameter of the core body 22 is substantially the same as the outer diameter of the protrusion 14 of the flange member 10. By combining the core member 20, a cylindrical inner surface that fits into the protrusion 14 is obtained. A semicircular cutout 28 is formed in the support surface 26 at a position corresponding to the cylindrical shaft of the core. When the two semicircular support surfaces 26 are combined to form a circular shape, the notch 28 becomes a circular through hole. Further, a dowel 27 that fits into the mounting hole 16 of the flange member 10 when the core member 20 is fitted into the flange member 10 is fixed to the support surface 26 at a position corresponding to the mounting hole 16. The dowel 27 being fixed to the support surface 26 includes the case where the dowel 27 is formed integrally with the support surface 26. The dowel 27 is fitted into the attachment hole 16 to fix the flange member 10 and the core member 20 together. The outer diameter of the dowel 27 is substantially the same as or slightly larger than the diameter of the mounting hole 16. Here, “slightly large” means that the dowel 27 is large enough to fit into the attachment hole 16 due to elastic deformation around the dowel 27 and the attachment hole 16. It is preferable that the dowel 27 has a chamfered tip (an end surface that begins to be fitted into the mounting hole 16) or a thin tip formed because the dowel 27 is easily fitted into the mounting hole 16. The number of dowels 27 is typically the same as the number of attachment holes 16, but if a large number of attachment holes 16 are formed, the number of dowels 27 may be smaller than the number of attachment holes 16. In the flange member 10 shown in FIG. 2, three mounting holes 16 are formed at equal intervals. Therefore, in the core member 20 shown in FIG. 3, two dowels 27 are fixed to one surface of the support surface 26, and one dowel 27 is fixed to the other surface, and when the two core members 20 are combined, the combined support There will be three dowels 27 on each side of the face 26. The mounting hole 16 and the dowel 27 are both preferably circular in cross section (the circular mounting hole 16 and the cylindrical dowel 27) because it is easier to manufacture. However, the mounting hole 16 and the dowel 27 are not limited to the circular cross section, and may have any shape. . Further, the cross-sectional shapes of the attachment hole 16 and the dowel 27 may be different.

  Returning to FIG. 1, a method for assembling the flange members 10 a and 10 b and the core members 20 a and 20 b to the bobbin 1 will be described. The dowel 27 of the core member 20 is inserted into the mounting hole 16 of the flange member 10. When the dowel 27 is fitted into the attachment hole 16, the flange member 10 and the core member 20 are fixed. Since the dowels 27 are fixed to both surfaces of the support surface 26 of the core member 20, the two flange members 10 are coupled with the core member 20 interposed therebetween. The two core members 20 are united by being fixed to the common flange member 10. When assembled as the bobbin 1, the semicircular support surfaces 26 of the core member 20 are combined into one circular plate, and a through hole is formed by a notch 28 in the center. The through holes are arranged in a straight line with the through holes 18 formed in the flange members 10 on both sides, and allow a rod, a wire, or the like to pass through the axial center of the bobbin 1.

  As described above, by inserting the dowel 27 of the core member 20 into the mounting hole 16 of the flange member 10, the two flange members 10 and the two windings divided by the surface 23 having an angle with the cylindrical shaft are divided. The core member 20 can be easily assembled into the bobbin 1 and is assembled by fitting the dowel 27 into the mounting hole 16, so that the bobbin 1 can be easily assembled with the two flange members 10 and the two The core member 20 can be disassembled. Further, since the cylindrical shape formed by the two core members 20 has an inner diameter that fits into the protrusion 14 of the flange member 10, the dowel 27 is formed in the attachment hole 16 between the flange member 10 and the core member 20. In addition to the insertion, the core body 22 is fixed even by friction caused by closely connecting the projections 14. As a result, the fixing state between the flange member 10 and the core member 20 becomes firm, and the bobbin 1 is prevented from being deformed by the relative displacement between the flange member 10 and the core member 20.

  Next, a bobbin 8 as a modification of the bobbin 1 will be described with reference to FIG. 4A is a perspective view of the assembled bobbin 8, and FIG. 4B is an exploded perspective view of the bobbin 8. Hereinafter, the difference from the bobbin 1 will be mainly described. In the bobbin 8, one dowel 127 is fixed to the flat surface 125 of the protrusion 124 of the flange member 120, and one attachment hole 126 and a through hole 128 are formed. Further, one attachment hole 137 and a notch 138 are formed in the support surface 136 of the core member 130.

  In order to assemble the bobbin 8 from the flange member 120 and the core member 130, the two flange members 120 a and 120 b are arranged so that the dowels 127 fit into the attachment holes 126. Then, the dowel 127 is inserted into the mounting hole 126 of the flange member 120 facing the core member 130 after passing through the mounting hole 137 of the support surface 136 of the core member 130. By assembling in this way, the two flange members 120a and 120b are fixed to each other when the dowel 127 is fitted into the mounting hole 126, the support surface 136 is sandwiched between the flat surfaces 125 of the protrusions 124 of the flange member 120, and the dowel 127 is By passing through the attachment hole 137, the core member 130 is fixed to the flange member 120. Compared to the bobbin 1, the bobbin 8 has a reduced number of dowels and mounting holes, and the structure is simplified. Therefore, it is particularly suitable for a bobbin having a small size or a bobbin having a small applied load.

  Next, a bobbin 2 as a modification of the bobbin 1 will be described with reference to FIG. 5A is a perspective view of the assembled bobbin 2, and FIG. 5B is an exploded perspective view of the bobbin 2. Hereinafter, the difference from the bobbin 1 will be mainly described. The bobbin 2 has a longer core than the bobbin 1. That is, the bobbin 2 has a wide width and can be wound with a longer length. It is the same as the bobbin 1 that the core is divided into two core members 40 by a surface 43 having an angle with respect to the cylindrical axis. Each of the core members 40 includes support surfaces 46 at two locations. Therefore, the length from the large-diameter side end surface 44 and the small-diameter side end surface 45 of the core member 40 to the support surface 46 is set to the length from the large-diameter side end surface 24 and the small-diameter side end surface 25 of the core member 20 in the bobbin 1 to the support surface 26. It is possible to use the flange member 10 that is common to the bobbin 1 by setting the length to the same length.

  In the bobbin 2, the dowel 36 is fixed to the flat surface 35 of the projection 34 projecting from the flange 32 of the flange member 30, and a mounting hole 47 is formed in the support surface 46 of the winding core 40. The dowel 36 being fixed to the plane 35 includes the case where the dowel 36 is formed integrally with the plane 35. Also in the bobbin 2, dowels may be fixed to the support surface 46 and attachment holes may be formed in the flat surface 35 of the protrusion 34. When the flange member 30 and the core member 40 are fixed by forming the attachment hole 47 in the support surface 46 and fitting the dowel 36 into the attachment hole 47, a force is generated between the flange member 30 and the core member 40. Even if transmission is performed, a bending moment hardly acts on the support surface 46, and the support surface 46 can be made thin. As described with respect to the bobbin 1, when the attachment hole 16 is formed in the flat surface 15 of the protrusion 14 of the flange member 10 and the dowel 27 is fixed to the support surface 26 of the core member 20, the flange member 10 and the core member 20. Are separately disassembled, the dowel 27 is surrounded by the core body 22, and the dowel 27 as a protrusion that is easily damaged can be protected. In addition, when the length of the core member 40 is short (when the width of the bobbin 2 is narrow), the interval between the support surfaces 46 in the axial direction is narrowed or becomes a single support surface. The dowels 36 of the flange members 30 on both sides do not interfere with each other. In the bobbin 2, four mounting holes 47 are formed in the circular plate in which the support surfaces 46 are combined, and the four dowels 36 are fixed to the flat surface 35 of the projection 34 of each flange member. The number of 36 is not limited to 4 as described in the bobbin 1. The bobbin 2 also has a through hole 38 formed at the center of the plane of the flange member 30. It is preferable that a notch 48 of the support surface 46 allows a rod or wire to pass through the axis of the bobbin 2.

  In the bobbin 2, the dowels 36 of the flange members 30 on both sides are fitted into the mounting holes 47 of the support surface 46 on the side close to the flange members 30 of the core member 40, so that the flange member 30 and the core member 40 are It is assembled to the bobbin 2. That is, the two flange members 30 are fixed to a circular plate in which different support surfaces 46 are combined. However, since the support surfaces 46 are fixed to the common core member 40, the two flange members 30. Are combined with the core member 40 to form the bobbin 2. A notch 48 is formed in the support surface 46, and when combined into a circular plate, a through hole is formed. The through hole 18 formed in the flange member 30 is aligned with a straight line, and a rod, a wire, or the like is attached to the bobbin 2 It is possible to pass through the shaft center.

  Next, a bobbin 3 as another modification of the bobbin 1 will be described with reference to FIG. 6A is a perspective view of the assembled bobbin 3, and FIG. 6B is an exploded perspective view of the bobbin 3. Hereinafter, the difference from the bobbin 1 will be mainly described. In the bobbin 3, no protrusion is formed on the flange member 50, and the flange member 50 is a flat plate. A through hole 58 is formed at the center of the flange member 50, and a dowel 56 is fixed. It is the same as the bobbin 1 that the core is divided into two core members 60 by a surface 63 having an angle with respect to the cylindrical axis. The core member 60 is provided with support surfaces 66 at both ends thereof. A mounting hole 67 is formed in the support surface 66. Therefore, by inserting the dowel 56 into the attachment hole 67, the flange member 50 and the core member 60 are fixed, and the bobbin 3 is assembled. Also in the bobbin 3, a notch 68 is formed on the support surface 66, and when combined to form a circular plate, a through hole is formed, aligned in a straight line with the through hole 58 formed in the flange member 50, a rod, a wire, or the like Can be passed through the axial center of the bobbin 3.

  If the flange member 50 is formed of a flat plate like the bobbin 3, the flange member 50 can be easily manufactured. In the bobbin 3, the bobbin 3 having different widths can be assembled using the same flange member 50 only by changing the length of the core member 60 having the support surfaces 66 at both ends. A groove 59 is formed at a position where the core body 62 of the core member 60 of the flange member 50 abuts, and the support surface 66 of the core member 60 is slightly shifted inward from the end surfaces 64 and 65, so If it is configured to engage with the groove 59 of the flange member 50, it is preferable that the flange member 50 and the core member 60 are firmly fixed. Alternatively, a portion of the core member 60 of the flange member 50 where the core body 62 and the support surface 66 abut is disk-shaped, and the core member 60 is provided with the support surface 66 at the end of the core body 62. The core member 60 may be engaged with the recess of the flange member 50. Also in this case, the fixing of the flange member 50 and the core member 60 is stable.

  With reference to FIG. 7, the bobbin 4 as another modification of the bobbin 1 is demonstrated. 7A is a perspective view of the assembled bobbin 4, and FIG. 7B is an exploded perspective view of the bobbin 4. Hereinafter, the difference from the bobbin 1 will be mainly described. In the bobbin 4, a surface 73 having an angle with respect to a cylindrical shaft that divides the core into two core members 70a and 70b is divided without reaching the end surface 75 of the core. That is, the end surface 75 corresponding to the large-diameter side end surface has a circular cross section. On the other hand, there is no end surface corresponding to the small-diameter side end surface, and a surface 73 having an angle with respect to the cylindrical axis constitutes another end surface. The core member 70 is provided with a support surface 76, and a dowel 77 is fixed to the support surface 76. The flange member 10 of the bobbin 4 is the same as the flange member 10 of the bobbin 1.

  The flange member 10 and the core member 70 are assembled to the bobbin 4 by fitting the dowels 77 of the support surface 76 into the mounting holes 16 of the flange member 10. In the bobbin 4, the length of the core member 70 for manufacturing the bobbin having the same width is shortened, which makes it easy to manufacture, that is, the mold can be made compact when plastic molding is performed. Moreover, since the end surface 75 connected to the protrusion 14 of the flange member 10 is circular and closed, it is difficult to deform and can be firmly connected to the flange member 10. When the surface 23 having an angle with respect to the cylindrical shaft that divides the core into two core members 20a and 20b, such as the bobbin 1, reaches the end surfaces 24 and 25 of the core, the winding Even when the length of the core is short, the angle of the surface 23 can be made relatively small with respect to the cylindrical axis, and as will be described later, the core is wound on a long object wound without a core. The angle can be set to be easy to insert.

  As shown in FIG. 8, the ends 82 and 84 of surfaces 82 to 84 having an angle with respect to the cylindrical shaft that divides the core of the bobbin 5 into two core members 80a and 80b are perpendicular to the cylindrical axis. You may comprise. Thus, even if the surface that divides the core is composed of the surface 83 having an angle with respect to the cylindrical axis and the vertical surfaces 82 and 84 or parallel surfaces, the “core is a cylindrical axis” It is included in the concept of “divided into planes with angles”. 8A is a perspective view of the assembled bobbin 5, and FIG. 8B is an exploded perspective view of the bobbin 5. Hereinafter, the difference from the bobbin 4 will be mainly described. In the bobbin 5, since the end portions 82 and 84 of the surfaces 82 to 84 having an angle with respect to the cylindrical axis are formed perpendicular to the cylindrical axis, it is divided into two as the bobbin 4 shown in FIG. There are no sharp edges on the surfaces 76 of the core members 70a and 70b that are connected to each other. Therefore, when inserting the core into the space inside the wound long object, there is no risk of damaging the long object with an acute point, and the operator handling is not damaged. If the winding core is divided by one plane 73 as in the bobbin 4, the structure is simplified and the joining of the two winding core members 70a and 70b is simple. And the manufacturing becomes easy.

  FIG. 9 shows a further modification of the bobbin 1. FIG. 9 is a perspective view of the bobbin 6 in which two flange members 90a and 90b and core members 91a and 91b are assembled with screws 93 and wing nuts 94 penetrating the flange members 90a and 90b. Although the number of screws 93 may be one, a through hole 98 is formed at the center of the flange member 90 so that a rod or wire can be passed through the axis of the bobbin 6. It may be arranged at a position away from. In such a case, it is preferable to arrange the screw 93 at a position symmetrical to the axial center so that the tightening force by the screw 93 acts evenly, and a plurality of screws 93 are used. The wing nut 94 may be a hex nut or a screw 93 with a head screw and one side a screw head. When the wing nut 94 is used, the wing nut 94 can be tightened by hand without using a tool such as a spanner.

  In the bobbin 6, the winding core has an angle with respect to the cylindrical shaft and is divided into two core members 91a and 91b on the surface reaching the end surface. You may divide | segment by the surface with an angle. In addition, the flange member 90 is formed of a flat plate, but for example, it has a projection like the bobbin 1 and is preferably connected to the core members 91a and 91b because it is more firmly connected. If the flange member 90 is a flat plate, the wing nut 94 can be easily tightened. Further, if the core member 91 is provided with a support surface (not shown) and a through hole through which the screw 93 passes is formed on the support surface, the flange member 90 and the core member 91 are firmly fixed to each other, which is preferable. When the flange member 90 and the core member 91 are fastened together by screws as in the bobbin 6, the assembly is ensured and the bobbin 6 can be prevented from collapsing even when a large external force is applied.

  FIG. 10 shows that the flange member 100 and the core member 110 are fixed by inserting the protrusion 104 of the flange member 100 into the large-diameter side end portion 114 of the core member 110, and the two core members 110a and 110b are wound. It is a disassembled perspective view of the bobbin 7 assembled by inserting and fixing the end part by the side of the surface 113 which has an angle to the cylindrical axis | shaft which divides | segments a core into two to the connection member 119. The connecting member 119 has an outer diameter that fits into the inner surface of the core member 110, and has a length equal to or shorter than the interval between the protrusions 104 of the flange members 100a and 100b when assembled to the bobbin 7. It is a member having. The connecting member 119 does not necessarily have a cylindrical shape. For example, the connecting member 119 may have irregularities on the outer surface thereof, and may be fitted to the core member 110 smoothly. Compared to the bobbin 1 or the like, the bobbin 7 does not require the operation of aligning the position of the dowel and the mounting hole when assembling the flange member and the core member, and is easy to assemble. Thus, the method of joining the flange member and the core member may be different from the method of inserting the dowel into the attachment hole.

  Next, with reference to FIG. 11, the modification of the further bobbin is shown. In FIG. 11, the core member 180 has a closed portion 182, the closed portion 182 fits into the protrusion 14 of the flange member 170, and the closed portion 182 is combined with another core member 180 to be perpendicular to the axis. 2A and 2B are diagrams for explaining bobbins 9 and 209 having a configuration that does not deviate in any direction. FIG. 3A is a perspective view of the bobbin 9 having a cover portion 183 in a closed portion 182, and FIG. ) Is a perspective view of the bobbin 209 that is configured not to be displaced in the direction perpendicular to the axis by combining the end faces of the winding core member 190 by making them Z-shaped.

  First, the bobbin 9 will be described. The flange member 170 of the bobbin 9 is basically the same as the flange member 10 (see FIGS. 1 and 2). However, as will be described later, the number of dowels 187 fixed to the support surface 186 of the core member 180 may not be one, and the number of mounting holes 16 formed in the flat surface 15 of the flange member 170 is one. It may not be, and other numbers may be sufficient. The core member 180 has a closed section 182 having a circular cross section that forms the circumference of the core so that the surface 181 having an angle with the cylindrical shaft does not reach the end surface on the large diameter side. A curved plate shape protruding along the outer periphery of the closed portion 182 toward the core member 180 to be combined (the core member 180b for the core member 180a and the core member 180a for the core member 180b). The cover portion 183 is formed. The shape of the cover portion 183 is not limited to the curved plate shape. For example, even if the cover portion 183 is formed of a plurality of rods, the small diameter side end portion 184 is in contact with the small diameter side end portion 184 of the core member 180 to be combined. It does not have to be shifted in the vertical direction (in a direction away from the protrusion 14 of the flange member 170). A single support surface 186 is formed on the core member 180, and one dowel 187 is formed on the support surface 186 so as to face the large diameter side. A notch 188 is formed in the support surface 186, and when the support surface 186 is assembled by assembling the core member 180, one through hole is formed. When the bobbin 9 is assembled, the through hole is located on a straight line connecting the through holes 18 formed in the flat surfaces 15 of the two flange members 170.

  A method for assembling the bobbin 9 will be described. The core member 180 is fitted into the protrusion 14 of the flange member 170. Since the core member 180 has the closed portion 182, the core member 180 is securely fixed by being fitted to the protrusion 14. Further, the dowel 187 is fixed to the support surface 186 of the core member 180, and the dowel 187 is fitted into the mounting hole 16 of the flange member 170, so that the core member 180 is more reliably and predeterminedly provided on the flange member 170. It is fixed with the positional relationship. However, dowels are not required. Next, the two core members 180a and 180b are combined. By combining, the cover portion 183 of one core member 180a (180b) overlaps with the small-diameter side end 184 of the other core member 180b (180a). That is, the small diameter side end 184 is sandwiched between the protrusion 14 of the flange member 170 and the covering portion 183. When the cover portion 183 overlaps with the small diameter side end portion 184 or when the small diameter side end portion 184 is sandwiched between the cover portion 183 and the protrusion 14, the small diameter side end portion 184 is formed in the direction perpendicular to the axis (protrusion It is prevented from shifting (in a direction away from 14). Therefore, the bobbin 9 can be assembled stably. Further, through the two flange members 170a and 170b, a through bolt 172 is disposed through the through hole 18 of the flange member and a through hole formed by combining the support surface 186 with the notch 188, and the nut 174 Tightened. As a result, the two flange members 170 a and 170 b and the core members 180 a and 180 b are fastened together and firmly assembled as the bobbin 9. By providing the through bolt 172 and the nut 174 as fastening members in this way, the assembly of the bobbin 9 becomes firm, and it is possible to prevent the bobbin from collapsing during movement and use. The fastening member may not be the through bolt 172 and the nut 174, but may be a screw 93 and a wing nut 94 as shown in FIG. 9, or a flange member is fixed to the through bar using a spring mechanism or the like. An instrument may be provided. In addition, when the through-bolt 172 and the nut 174 are used, it can tighten firmly, and if it uses a screw and a wing nut, it can clamp | tighten without a tool. Even if the fastening member is not provided, the bobbin 9 may be assembled by the dowel 187 or by sandwiching the small-diameter side end portion 184 between the cover portion 183 and the protrusion 14. Moreover, the bobbin 9 can be suspended by extending the through-bolt 172 long and supporting the through-bolt 172 rotatably.

  In the bobbin 209 shown in FIG. 11 (c), the cover part 183 is not provided. Instead, the end face where the two core parts 190a and 190b meet is viewed from the side of the bobbin 209 placed as shown in FIG. 11 (c). (When viewed from the direction perpendicular to the paper surface), it is formed in a slanted Z shape. That is, the end surface 194 on the small diameter side is not a surface perpendicular to the axis, but is inclined so that the end surface 194 retracts from the intersection 195 with the surface 191 having an angle with the cylindrical axis at the top. In addition, the surface 193 of the closed portion 192 that is combined with the end surface 194 is formed so as to protrude so that the point corresponding to the intersection 195 is the bottom. By matching the inclined surfaces in this way, it is possible to prevent the end portion on the small diameter side from shifting in the direction perpendicular to the axis (in the direction away from the protrusion 14).

  Then, with reference to FIG. 12, the method to attach the elongate thing wound without the core to the bobbin which concerns on this invention is demonstrated. In FIG. 12, the bobbin 1 shown in FIG. 1 is used, a hose 152 is wound as a long object, and a winding hose 150 bundled with a tape 154 is described. 12A to 12F, the procedure for attaching the winding hose 150 to the bobbin 1 will be described in the order of work. The winding hose 150 is wound without a core and the diameter of the inner cylindrical space is the same as or slightly smaller than the outer diameter of the core, and is substantially the same as the length between the flanges 12 (see FIG. 2) of the bobbin 1. It is wound in the same width and is kept in its shape by being bundled at three locations with tape 154. The number of tapes is not limited to three.

  First, as shown in FIG. 12A, one core member 20a is connected to one flange member 10a. The winding core member 20a is disposed so that the large-diameter side end 24 (see FIG. 1) is connected to the flange member 10a. Next, as shown in FIGS. 12B and 12C, the core member 20a is inserted into the space inside the winding hose 150 from the small diameter side end 25 (see FIG. 1). Since it inserts in the space inside the winding hose 150 from the small diameter side edge part 25, it is easy to insert. And as shown in (c), it inserts deeply until the side surface of the winding hose 150 contacts the flange member 10a. Next, as shown in FIG. 12D, the other flange member 10b is also connected to the other core member 20b. The core member 20b is disposed so as to connect the large-diameter end 24 to the flange member 10b. Then, the flange member 10 b and the core member 20 b are rotated so that the core members 20 a and 20 b are connected, and the core member 20 b is inserted into the space inside the winding hose 150 from the small diameter side end portion 25. Also at this time, since the small diameter side end portion 25 is inserted into the space inside the winding hose 150, it is easy to insert. Then, when inserted into the back, the diameter of the cylindrical space inside the winding hose 150 is the same as or slightly smaller than the outer diameter of the winding core, so that the winding core member 20b is wound around the winding hose 150. Of the core member 20a and the core member 20b, the surfaces 23 having an angle come into contact with the cylindrical shafts of the core member 20a and the core member 20b. Therefore, when the core member 20b is further inserted into the back, the surface 23 having an angle with respect to the cylindrical shaft of the core member 20a causes the surface 23 having an angle with respect to the cylindrical shaft of the core member 20b to drive a wedge. The cylindrical space inside the winding hose 150 is pushed and expanded by the core member 20b. And the dowel 27 (refer FIG. 1) of the core member 20a fits in the attachment hole 16 (refer FIG. 1) of the flange member 10b, the dowel 27 of the core member 20b fits in the attachment hole 16 of the flange member 10a, As shown in FIG. 12E, the bobbin 1 is assembled. If the bobbin 1 is attached to the winding hose 150, by cutting and removing the tape 154, the winding hose 160 in which the hose 152 is wound around the bobbin 1 is obtained as shown in FIG.

  Since the angled surfaces 23 abut against the cylindrical shafts of the core member 20a and the core member 20b, the core members 20a and 20b are joined to each other so as to drive a wedge. The bobbin 1 can be easily attached to the winding hose 150 in which the diameter of the cylindrical space is the same as or slightly smaller than the outer diameter of the winding core. Furthermore, since the core members 20a and 20b are inserted into the inner cylindrical space so that the inner cylindrical space of the winding hose 150 is expanded, the innermost hose 152 and the core Is firmly attached, and the bobbin 1 and the hose 152 do not idle.

  When the winding hose 160 is manufactured as described above, for example, only the winding hose 150 is shipped at the factory, and the bobbin 1 is prepared at the dealer, so that the winding hose 160 can be easily made at the dealer. The bobbin 1 can be reused, the bobbin 1 or a part thereof is not discarded, and it is not necessary to return it to the factory.

  In the above description with reference to FIG. 12, the bobbin 1 is used as an example, but the other bobbins 2 to 9 and 209 described so far, or combinations and modifications thereof, the core and the flange If the bobbin is provided with a bobbin that is divided into at least two planes having an angle with respect to the axis, the same can be used.

  In the description so far, the core has been described as having a cylindrical shape, but the core may be any cylindrical shape around which a long object can be wound, and the cross section thereof is a polygon such as a triangle or a square, or It may have unevenness like a star shape, and a groove may be formed on the surface or a hole may be formed. The cylindrical shape includes these shapes. When the cross section of the core is made polygonal or uneven, the long apex or convex portion of the core makes strong contact with the long object, and the adhesion between the bobbin and the long object increases. Forming grooves and holes contributes to resource saving of the core material, and can reduce the weight of the bobbin.

  In the description so far, the flange member and the core member have been described as separate bodies, but may be integrally formed. When formed integrally, the joint between the core and the flange becomes more rigid, and the shape of the bobbin is stabilized.

  In the above description, the two flange members and the two core members have been described as having the same shape, but each may not be the same shape. Further, although the core has been described as being divided into two core members, the core may be divided into three or more. When the core is divided into three or more, it is sufficient that at least one part is divided by a surface having an angle with respect to the shaft, and the long length wound on the surface having an angle with respect to the shaft. What is necessary is just to insert a core member from the both sides of the space part inside a thing.

  In the description so far, the bobbin has been described as being made of plastic, but the material of the bobbin is not limited to plastic, and other materials may be used. If it is made of plastic, it is lightweight, easy to mold, can be molded integrally with the dowel, and is slightly elastically deformed when the dowel is inserted into the mounting hole. Can be fixed to.

  In the above description, the hose is wound around the bobbin. However, the hose is not limited to the hose, and other long objects such as a rope and an electric / communication cord may be used.
