You can also

  The long body only needs to be a long body that extends in the axial direction and can constitute the long decorative article, even if it is a flexible long body formed of rubber, fiber, etc. It may be a long body that is not bent or is not easily bent. As such a long body, for example, a bendable long body in which a rubber magnet is coated with a resin is preferably used. This long body is adjusted to an appropriate outer diameter and axial length according to the application.

  The connector may be any member that can be attached to both ends of the long body and connect the both ends. For example, the connector includes the male connector and the female connector. There is a connector that can connect both ends of the elongated body to each other by detachably engaging the tool and the female connector. Such a connector is formed into a shape of, for example, a tube, an ellipsoid, or a sphere, and a portion that contacts the body is formed of an elastic material such as rubber in order to prevent injury to the body. Examples of the female connector include a tubular body having an axial hole that penetrates in the axial direction thereof and into which the elongated body is inserted. Examples of the tubular male connector include the axial hole. Examples thereof include a tubular body having a protruding portion that is detachably inserted at the distal end and a shaft hole into which the long body is inserted. When the female connector and the tubular male connector have elasticity, each of the female connector and the tubular male connector has a diameter smaller than the outer diameter of the long body. It has a shaft hole and the shaft hole, and is fixed to the end of the elongated body by its own elastic force.

  As a long decorative article suitably manufactured by the long decorative article manufacturing apparatus and manufacturing method according to the present invention, a connector is attached to each end of a long object formed by covering a rubber magnet with a resin. Examples of such magnetic therapy devices include magnetic necklaces and magnetic bracelets.

  As the magnetic necklace, for example, as shown in FIGS. 11 and 12, a long body 51, a tubular elastic member 54 attached to one end of the long body 51, and the tubular elastic member 54 And a tubular male connector 52 having a connecting member 55 that is removably inserted into a tubular elastic female connector 53 attached to the other end of the long body 51. The magnetic necklace 50 is mentioned. In other words, the magnetic necklace 50 is attached to the long body 51, the tubular elastic female connector 53 attached to the other end of the long body 51, and one end of the long body 51. A tubular elastic member 54, and a tubular male connector 52 including a connecting member 55 which is inserted into the tubular elastic member 54 and is removably inserted into the tubular elastic female connector 53.

  As shown in FIG. 11, the magnetic necklace 50 has a long body by inserting the connecting member 55 of the tubular male connector 52 into the shaft hole 61 of the tubular elastic female connector 53 and inserting them. The two ends of 51 are connected and used in an annular shape.

  The elongate body 51 is formed by covering a rubber magnet with a resin, one end of which is housed in the tubular male connector 52, and the other end is housed in the tubular elastic female connector 53. . In the long body 51, a magnet material is dispersed in rubber, and a long rubber magnet extending in one direction is covered with a resin. The rubber magnet is a mixture of rubber and a magnet material such as ferrite, and the mixing ratio of the rubber and the magnet material is preferably 80 to 95% by mass for the magnet material and 5 to 20% by mass for the rubber. If the rubber magnet is formed with the mixing ratio in the above range, appropriate flexibility can be obtained, so that it can be easily worn on the body, and the magnetic flux density can be increased within the appropriate range, so that health is promoted. Increases effectiveness. As the rubber and the magnet material, known materials can be used without particular limitation. The rubber magnet has a cross section formed into a circle having a diameter of about 3 to 8 mm. As the resin, known ones are used without particular limitation, and examples thereof include silicone resins and urethane resins. The resin layer made of the resin has a thickness of about 0.1 to 0.5 mm, for example. Thus, the elongate body 51 can also be referred to as a solid substance consisting of a rubber magnet and a resin layer.

  Assuming that magnet material particles, for example, ferrite particles, are magnetized in the same direction, for example, the upper direction of the cross section, in the transverse section of the long body 51, the adjacent N poles and S poles of the magnet material particles cancel each other. It is virtually magnetized in any cross section of the body 51. The direction of the magnetization may be different in the direction of the magnetic field lines coming out of the N pole in the length direction of the long body 51, for example, staggered, spiral, or randomly changed, and the magnetic effect Can be changed to be higher. As the strength of magnetization, the magnetic flux density on the surface of the long body 51 is preferably adjusted to a range of 40 to 70 millitesla.

  The tubular male connector 52 includes a tubular elastic member 54 and a connection member 55 that is inserted into the tubular elastic member 54 and is removably inserted into the tubular elastic female connector 53. .

  As shown in FIG. 12, the tubular elastic member 54 is formed of an elastic material having elasticity, for example, rubber or the like, and is formed into a tubular body having a shaft hole 61 penetrating along the axis thereof. Attached to one end. The tubular elastic member 54 may be a cylindrical body having a circular truncated cone part whose outer diameter gradually decreases toward one end part, and the entire tubular elastic member 54 is in a cylindrical state having a uniform outer diameter. There may be. In this example, the tubular elastic member 54 is made of silicone rubber, and a part of the tubular elastic member 54 is a cylindrical body having a truncated cone portion whose outer diameter gradually decreases toward one end portion.

  As shown in FIG. 12, the shaft hole 61 has two inner diameter changing portions whose inner diameters are reduced or enlarged, and penetrates the tubular elastic member 54 along the axis. That is, the shaft hole 61 includes a first shaft hole 62 that houses and elastically holds the end portion of the long body 51 and also houses a first bulging portion 67 of the connecting member 55 described later, and the first shaft. The second shaft hole 63 that has a smaller diameter than the hole 62 and holds the shaft 66 of the connection member 55 and the third shaft hole 64 that accommodates the collar portion 68 of the connection member 55 share the axis of the tubular elastic member 54. The first shaft hole 62 is opened at one end of the tubular elastic member 54, and the third shaft hole 64 is opened at the other end of the tubular elastic member 54. The first shaft hole 62 can accommodate the first bulging portion 67 and has an inner diameter smaller than the outer diameter of the long body 51, and the second shaft hole 63 is smaller than the inner diameter of the first shaft hole 62 and has the shaft 66. The third shaft hole 64 has a larger inner diameter than the second shaft hole 63 and can accommodate the flange portion 68.

  The connecting member 55 includes a shaft 66 projecting from the tubular elastic member 54 with a first bulging portion 67 inserted into the tubular elastic member 54 and a second bulging portion 69 of the tubular elastic female connector 53 described later. The shaft hole 61 is removably inserted. As shown in FIG. 12, the connecting member 55 is made of a material having rigidity, for example, metal, resin, or the like, and is formed in a so-called “dumbbell shape” having a flange portion 68 at a substantially central portion of the axis. That is, the connecting member 55 includes a shaft 66 having a substantially circular cross section extending in one direction, a first bulging portion 67 whose outer peripheral surface bulges in the radial direction at one end of the shaft 66, and the other of the shaft 66. A ring-shaped ridge projecting perpendicularly to the axis on a shaft 66 between the first bulging portion 67 and the second bulging portion 69, a second bulging portion 69 whose outer peripheral surface bulges in the radial direction Part 68. The shaft 66 can be inserted into the tubular elastic member 54, and has an axial length and an outer diameter that can be removably inserted into the tubular elastic female connector 53. In particular, a portion between the first bulging portion 67 and the flange portion 68 has an outer diameter and an axial length that can be accommodated in the second shaft hole 63. The intermediate portion is inserted into the tubular elastic female connector 53 and has an axial length and an outer diameter that can be accommodated in the third shaft hole 64 and the second shaft hole 63. In other words, the portion between the first bulging portion 67 and the flange portion 68 has an axial length substantially the same as the axial length of the second shaft hole 63, and between the flange portion 68 and the second bulging portion 69. This part has an axial length substantially the same as the total axial length of the second axial hole 63 and the third axial hole 64 of the tubular elastic female connector 53.

  The first bulging portion 67 is formed in a cylindrical shape having a truncated cone shape at the tip, and when the first bulging portion 67 is inserted or fitted into the tubular elastic member 54, the rear end surface of the first bulging portion 67 is the first shaft hole. 62 and the second shaft hole 63 are engaged with the stepped portion due to the inner diameter difference.

  The flange portion 68 is accommodated in the third shaft hole 64 when inserted or fitted into the tubular elastic member 54, and the end surface on the first bulge portion 67 side is the second shaft hole 63 and the third shaft hole 64. It is designed to be locked to the stepped portion due to the difference in inner diameter. That is, the position of the connecting member 55 in the axial direction is determined by inserting the first bulging portion 67 and the flange portion 68 into the shaft hole 61.

  The second bulging portion 69 is formed in a cylindrical shape having a hemispherical tip, and passes through the third shaft hole 64 and the second shaft hole 63 when inserted into the tubular elastic female connector 53. And the rear end surface of the second bulging portion 69 is locked to the stepped portion due to the inner diameter difference between the first shaft hole 62 and the second shaft hole 63, and the tubular male connector 52 The tubular elastic female connector 53 is connected. The shaft 66, the first bulging portion 67, the collar portion 68, and the second bulging portion 69 may have dimensions enough to be accommodated in the tubular elastic member 54 or the tubular elastic female connector 53. It is preferable that the outer diameter is slightly larger than the diameter of the shaft hole 61 of the member 54 or the shaft hole 61 of the tubular elastic female connector 53 because these elastic forces hold the member. In the connecting member 55, the outer diameter of the flange portion 68 is substantially the same as the maximum outer diameter of the second bulge portion 69 and is smaller than the maximum outer diameter of the first bulge portion 67. Since the first bulging portion 67 has a larger maximum outer diameter than the second bulging portion 69 in this way, the tubular male connector 52 and the tubular elastic female connector 53 are connected and detached. Even so, the connecting member 55 maintains the state of being inserted into the tubular elastic member 54.

  As shown in FIG. 12, the tubular elastic female connector 53 is formed in a tubular body having a shaft hole 61 that penetrates along the axis of the elastic material having elasticity, and the other of the long body 51. It is attached to the end of the. The tubular elastic female connector 53 is basically the same as the tubular elastic member 54. That is, it can be said that the tubular male connector 52 is composed of the tubular elastic female connector 53 and the connecting member 55. Therefore, the magnetic necklace 50 includes tubular elastic members 54 attached to both ends of the long body 51, one tubular elastic member 54 is a tubular elastic female connector 53, and the other tubular elastic member 54 is connected to the connecting member. 55 is inserted into a tubular male connector 52.

The small diameter portion 16 has the tip restricting portion 16a at its tip, particularly at the tip surface. In the present invention, the intermediate shaft body does not have to include the small diameter portion and the tip restricting portion. However, if the medium shaft body includes the small diameter portion 16 and the tip restricting portion 16a like the intermediate shaft body 11, the medium shaft body is inserted into the tube body 12. Since the displacement can be regulated by contacting the end surface of the elongated body 51, the relative positional relationship between the tubular elastic member 54 and the elongated body 51 can be easily and stably maintained. As a result, it is particularly preferable in that a long decorative article having the same quality can be manufactured with higher yield. The tip restricting portion 16a may be in any form that can abut against the long body 51 and restrict the displacement thereof, and is flat in this example.

  The axial lengths of the large-diameter portion 14, the outer-diameter changing portion 15, and the small-diameter portion 16 are appropriately adjusted according to the tubular elastic member 54, the long body 51, and the like as well shown in FIG. The large diameter portion 14 is a member that arranges and supports the outer diameter changing portion 15 so that the outer diameter changing portion 15 protrudes from the distal end portion of the tube body 12 when the middle shaft body 11 is inserted into the tube body 12 described later. As long as such a function is exhibited, the form of the large diameter portion 14 is not particularly limited. For example, the large-diameter portion 14 may be a solid body, and the end portion may be open or closed.

  As shown in FIG. 4 (b), the tubular body 12 is a tubular member having both ends opened, and the middle shaft body 11 is inserted therethrough and faces in a direction opposite to the direction in which the middle shaft body 11 is inserted. In other words, the long body 51 is inserted in the same direction as the direction in which the tubular elastic member 54 is pushed, and the connection member 55 is inserted so as to face the long body 51. The tubular body 12 has an inner diameter that is substantially the same as or larger than the outer diameter of the large-diameter portion 14, the long body 51, and the connecting member 55, and supports and fixes the tubular elastic member 54 that is disposed so as to be covered. . The tubular body 12 is shorter than the axial length of the middle shaft body 11. In this example, when the tubular body 12 is provided in a standing state on the tubular body moving means 42 described later, the distal end portion and the large diameter portion 14 of the tubular body 12 are provided. It has an axial length that is substantially coincident with the tip portion. It is preferable that the tubular body 12 is adjusted to a thin thickness within a range in which the strength can be maintained because the tubular elastic member 54 can be easily packaged.

  As shown in FIG. 4 (c), the holding shaft body 13 is a cylindrical member or a tubular member having a shaft hole 17 that opens to the tip portion, that is, the tip surface and holds the connection member 55 in an upright state. The middle shaft body 11 is inserted and arranged in the tube body 12 that has been removed or detached. The holding shaft body 13 is a solid cylindrical member having the shaft hole 17. For example, as shown in FIG. 7A, the holding shaft body 13 is configured such that the shaft hole 17 accommodates a part of the second bulging portion 69 and the flange portion 68 of the connecting member 55, and the inner periphery thereof. The surface comes into contact with the outer peripheral surface of the flange portion 68, and the standing state of the connection member 55 is stabilized. In this way, the holding shaft body 13 holds the connecting member 55 in an upright state in which the first bulging portion 67 protrudes from the opening so as to be substantially coaxial with the holding shaft body 13. Therefore, the shaft hole 17 has an inner diameter capable of accommodating the second bulging portion 69 and the flange portion 68, and a depth capable of accommodating from the tip of the second bulging portion 69 to a part of the flange portion 68. The front end surface of the holding shaft 13 is substantially perpendicular to the axis. The holding shaft body 13 has an outer diameter that is substantially the same as or smaller than the inner diameter of the tube body 12, and has an axial length that is shorter than the axial length of the tube body 12, specifically as described later. In addition, the connecting shaft 55 has an axial length that allows the connecting member 55 to be disposed inside the tubular body 12 when the holding shaft body moving means 43 is provided in an upright state.

  For example, as shown in FIG. 1, the manufacturing apparatus 1 includes a moving unit 40 that moves the tube body 12, the middle shaft body 11, and the holding shaft body 13 back and forth independently in the axial direction of the middle shaft body 11. Yes. The moving means 40 is provided with the middle shaft body 11 erected, and a middle shaft body moving means 41 for moving the middle shaft body 11 back and forth in the axial direction and the radial direction of the axis, and the tube body 12 erected. A tube moving means 42 for moving the tube body 12 back and forth in the axial direction and a holding shaft body 13 are erected, and a holding shaft body for moving the holding shaft body 13 back and forth in the axial direction and the radial direction of the axis. And moving means 43.

  The middle shaft body moving means 41 moves the middle shaft body 11 back and forth in the axial direction so as to be inserted into, removed from, or retracted from the tube body 12, and moves the middle shaft body 11 back and forth in the radial direction of the axis line. The middle shaft body 12 that has been removed from or retracted from the tube body 12 is retracted from this position. The tubular body moving means 42 has a through hole 44 through which the middle shaft body 11 and the holding shaft body 13 penetrate, and the tubular body 12 is erected so as to share the center with the through hole 44 and surround the through hole 44. ing. The holding shaft body moving means 43 moves the holding shaft body 13 back and forth in the axial direction so as to be inserted into, removed from, or retracted from the tube body 12, and moves the holding shaft body 13 back and forth in the radial direction of the axis line. It arrange | positions in the position which shares an axis line with the pipe body 12, and retracts the holding shaft body 13 from this position. In this example, each of the middle shaft body moving means 41, the tube body moving means 42, and the holding shaft body moving means 43 is a flat plate-like member, and can be independently moved forward and backward as described above. Are connected to cylinders, etc. Since the middle shaft body moving means 41, the tube body moving means 42, and the holding shaft body moving means 43 are configured in this way, the middle shaft body 11 and the holding shaft body 13 are inserted into, inserted into, or removed from the tube body 12, respectively. be able to. FIG. 1 shows a state in which the middle shaft body 11 is inserted into the tube body 12 by the middle shaft body moving means 41 and the holding shaft body 13 is waiting at a position where the holding shaft body moving means 43 does not share the axis line with the tube body 12. ing.

  As shown in FIGS. 1 and 2, the regulating member 10 has a regulating surface 19 formed around a through hole 18 through which the tube body 12 penetrates, and the tube body 12 projects from the through hole 18. Are arranged as follows. The restricting member 10 restricts the displacement of the tubular elastic member 54 sheathed on the tubular body 12 by the restricting surface 19. Specifically, the restricting member 10 extends along the axis C direction with respect to the restricting member 10. It restrains or prevents the tubular elastic member 54 that is sheathed on the outer periphery of the tubular body 12 from retreating in the same direction together with the tubular body 12 when it is relatively retracted. In this example, the regulating member 10 is a flat having a through hole 18 through which the tubular body 12 passes and a regulating surface 19 which is formed around the through hole 18 and regulates or prevents displacement of the tubular elastic member 54 such as retreat. It is a plate-like member. The regulating member 10 is a driving means (not shown) such as a motor, so as to be able to move forward and backward along the direction of the axis C independently of the intermediate shaft moving means 41, the tube moving means 42 and the holding shaft moving means 43. It is connected to a cylinder or the like, and is arranged at a position where the axial length of the tubular body 12 protruding from the regulating member 10 is substantially the same as the axial length of a tubular elastic member 54 described later.

  The pushing member 20 in the manufacturing apparatus 1 is, for example, as shown in FIG. 5A, an end portion of a tubular elastic member 54 that is inserted and arranged in an outer diameter changing portion 15 protruding from one opening of the tube body 12. Are arranged in the extending direction of the axis C so as to be able to move back and forth along the axis C of the middle shaft body 11. As will be described later, the pushing member 20 moves forward and backward along the direction of the axis C of the middle shaft body 11, and inserts and arranges the tubular elastic member 54 inserted into the middle shaft body 11 protruding from the tube body 12 in the direction. The tubular elastic member 54 is covered and arranged on the tube body 12 while being expanded in diameter by the outer diameter changing portion 15. Specifically, as shown in FIGS. 1 to 3, the pushing member 20 includes a first pushing arm 21A and a second pushing arm 21B, and the first pushing arm 21A and the first pushing arm 21B. The two pushing arms 21B are provided with pushing portions 22A and 22B, which will be described later, at their ends. More specifically, as shown in FIGS. 1 to 3, the pushing member 20 is formed around a first through recess 24 </ b> A that forms a through portion 27 described later, and the first through recess 24 </ b> A. The penetrating portion 27 is formed together with the first pushing arm 21A having the first pushing portion 22A having the first abutting portion 23A that abuts the end portion of the tubular elastic member 54, and the first penetrating recess 24A. A second pushing portion 22B having a second pushing portion 22B having a second penetrating recess 24B and a second abutting portion 23B formed around the second penetrating recess 24B and abutting the end of the tubular elastic member 54. It comprises an advance arm 21B.

  The first pushing arm 21A has a substantially quadrangular prism shape, and includes one first pushing portion 22A having a first penetrating recess 24A and a first contact portion 23A at one end. A first tip member 25A is mounted, and a first connecting member 26A (see FIGS. 1 and 2) connected to a pushing member moving means 44 described later is mounted on the other end.

  1 and 3, the first tip member 25A is a smooth plate-like member, and has a substantially semicircular shape penetrating in an end surface on the second pushing arm 21B side to be described later in the thickness direction. A first through-hole recess 24A is formed. That is, the first tip member 25A includes a flat surface and the first through recess 24A formed substantially perpendicular to the surface, and the first pushing portion 22A includes the first through recess 24A and the first through hole. The first contact portion 23A is a surface surrounding the recess 24A. As shown in FIGS. 1 and 2, the first tip member 25 </ b> A has a desired surface on the middle shaft body 11 when the first pushing arm 21 </ b> A is supported by the pushing member moving means 44. The end face is positioned so as to face the axis C of the middle shaft body 11.

  The amount of depression of the first through recess 24 </ b> A is such that the concave surface of the first through recess 24 </ b> A contacts the outer surface of the middle shaft body 11 when the pushing member 20 moves forward and the tubular body 12 is covered with the tubular elastic member 54. Alternatively, the outer diameter and inner diameter of the tubular elastic member 54, the shape and size of the first tip member 25A, and the amount of protrusion from the side surface of the first push arm 21A toward the second tip member 25B so as to be non-contact. It is determined accordingly. In short, the amount of recess of the first through recess 24A is such that when the tubular elastic member 54 is pushed forward, the first contact portion 23A that contacts the tubular elastic member 54 exists, and the recess of the first through recess 24A exists. The surface is determined so as to be in contact with or not in contact with the outer surface of the middle shaft body 11. As will be described later, it is preferable that the concave surface of the first through recess 24 </ b> A is not in contact with the outer surface of the middle shaft body 11.

  In the manufacturing apparatus 1, the first connecting member 26 </ b> A is pushed so that the first pushing arm 21 </ b> A is rotatably supported by the pushing member moving means 44 as shown in FIGS. 1 and 2, for example. A shaft body or the like that is supported by a bearing of the advance member moving means 44 is provided.

  The second pushing arm 21B is basically the same as the first pushing arm 21A, as shown in FIGS.

In particular, the first push arm 21A and the second push arm 21B are close to or remote from each other so that the center of the center shaft body 11 is located substantially on the axis C (see FIG. 3). The pushing member is rotatable so that the first through recess 24A and the second through recess 24B facing each other are close to or remote from each other, in other words, so that the through portion 27 can be opened and closed. The first connecting member 26A and the second connecting member 26B are supported by the moving means 44.

  In the pushing member 20 supported in this way, the through portion 27 is equal to or larger than the outer diameter of the small-diameter portion 16 in the middle shaft body 11 and the outer diameter of the tubular elastic member 54 inserted and arranged in the middle shaft body 11. The dimensions are the same or less than the outer diameter. For example, in this example, as shown in FIG. 3, the penetrating portion 27 is a substantially circular cutout portion in which a substantially semicircular first penetrating recess 24A and a second penetrating recess 24B face each other. The diameter has a dimension in the above range. Specifically, the diameter of the penetrating portion 27 is slightly larger than the outer diameter of the small diameter portion 16.

  As shown in FIGS. 1 and 2, the pushing member moving means 44 has a plate shape and serves as a bearing that supports the shafts of the first connecting member 26A and the second connecting member 26B therein. A recess is formed. The pushing member moving means 44 is connected to driving means (not shown) such as a motor and a cylinder so as to be able to move forward and backward together with the first pushing arm 21A and the second pushing arm 21B of the pushing member 20. Yes.

  The opening amount adjusting means 30 in the manufacturing apparatus 1 is configured so that the middle shaft body 11 moves according to the relative position of the pushing member 20 along the axis C direction of the middle shaft body 11, in other words, according to the forward and backward movement of the pushing member 20. It is a member that adjusts the separation distance, that is, the opening amount of the penetrating part 27 that penetrates. When the manufacturing apparatus 1 includes the opening amount adjusting means 30 that maintains the non-contact state between the penetrating portion 27 and the outer diameter changing portion 15 during operation, the insertion jig 10 and the penetrating portion 27 are damaged due to wear or the like. This is preferable because the tubular elastic member 54 can be uniformly mounted on the long body 51 and high durability can be exhibited.

  Specifically, as shown in FIGS. 1 to 3, the opening amount adjusting means 30 gradually decreases in outer diameter toward the tip at an inclination ratio corresponding to the inclination ratio of the outer diameter changing portion 15.

As will be described later, the opening amount adjusting means 30 is configured such that the first guided portion 37A and the second guided portion 37B slide in the axial direction on the outer peripheral surface of the guide outer diameter changing portion 34. The first pushing arm 21A and the second pushing arm 21B can be brought close to or remote from each other via the first adjusting arm 32A and the second adjusting arm 32B.

  As shown in FIGS. 1 and 2, the guide member 31 has a rod shape in which the large diameter portion 35, the guide outer diameter changing portion 34, and the small diameter portion 36 share a central axis. Specifically, the guide member 31 is provided in a standing state on a fixed substrate (not shown), and is provided with a large-diameter portion 35 having a substantially constant outer diameter and an end portion of the large-diameter portion 35, and toward the tip. The guide outer diameter changing portion 34 gradually decreases in outer diameter, and the small diameter portion 36 is provided continuously from the end of the guide outer diameter changing portion 34 and has a substantially constant outer diameter smaller than the large diameter portion 35. ing. The guide outer diameter changing portion 34 may be a frustum-shaped guide taper portion whose outer diameter gradually decreases at a constant rate toward the tip, and the outer diameter gradually decreases at a different rate toward the tip. A guide curved surface portion having a curved surface may be used, and in this example, the guide taper portion is used.

  The guide member 31 has outer diameters of the large diameter portion 35, the guide outer diameter changing portion 34, and the small diameter portion 36 so that the penetrating portion 27 has an opening amount that does not contact the outer peripheral surface of the outer diameter changing portion 15. The axial length is adjusted. In this example, the position (altitude) in the direction of the axis C between the penetrating portion 27 and a first guided portion 37A and a second guided portion 37B described later, and the inclination ratio of the outer diameter changing portion 15 in the intermediate shaft body 11 In consideration of the above, the inclination ratio and axial length of the guide outer diameter changing portion 34 and the axial length of the large diameter portion 35 are determined.

  As shown in FIGS. 1 to 3, the first adjustment arm 32 </ b> A has a first connecting portion 38 </ b> A that is a rectangular column whose one end protrudes substantially horizontally from the side surface of the first pushing arm 21 </ b> A, and its tip. And a first guided portion 37A. As shown in FIG. 3, the first guided portion 37A is formed in a substantially arc shape penetrating in the thickness direction on the side surface of the flat rectangular column body on the first adjusting arm 35 side described later. It is a notch recess. The concave amount of the first guided portion 37A is such that the concave surface of the first guided portion 37A is brought to the outer surface of the guide member 31 when the pushing member 20 moves forward and the tubular body 12 is inserted and arranged in the tubular elastic member 54. In accordance with the shape and dimensions of the flat rectangular column body, the amount of protrusion on the second guided portion 37B side from the first connecting portion 38A, the inclination ratio of the outer diameter changing portion 15, etc. Has been.

  The second adjustment arm 32B is basically the same as the first adjustment arm 32A, as shown in FIGS.

  The first guided portion 37A and the second guided portion 37B that face each other are positioned substantially on the axis of the guide member 31, as shown in FIG. The first guided portion 37A and the second guided portion 37B are slid on the outer peripheral surface of the guide outer diameter changing portion 34 in a state of being opposed to each other, so that the inclination ratio of the guide outer diameter changing portion 34 is increased. Accordingly, the distance between each other is remote or close.

  37 A of 1st guided parts and the 2nd guided part 37B are more than the outer diameter of the small diameter part 36 in the guide member 31, Comprising: The maximum outer diameter of the guide outer diameter change part 34, ie, less than the outer diameter of the large diameter part 35, Have the following dimensions. For example, in this example, as shown in FIG. 3, the first guided portion 37A and the second guided portion 37B face each other to form a substantially circular space. And the diameter of this space part has the dimension of the said range. Specifically, the diameter of the substantially circular space part formed by 37 A of 1st guided parts and the 2nd guided part 37B is small diameter. The outer diameter of the portion 36 is almost the same.

  As shown in FIG. 1, the elastic member 33 may be a member that can connect the first push arm 21 </ b> A and the second push arm 21 </ b> B close to or remotely from each other along the rotation direction. Examples thereof include a tension coil spring and a compression coil spring. In this example, a tension coil spring is installed as the expansion / contraction member 33 above the first pushing arm 21A and the second pushing arm 21B, that is, on the pushing member moving means 44 side. Accordingly, the pushing member 20 is normally brought into the initial state shown in FIGS. 1 to 3 by the telescopic member 33, and the first pushing arm against the stretching force of the telescopic member 33 by the opening amount adjusting means 30. 21A and the second pushing arm 21B are rotatable so as to be remote along the rotation direction.

  In the manufacturing apparatus 1, the driving timing and driving speed of the moving means 40, the pushing member moving means 44 and the regulating member 10 may be controlled by a control device such as a computer, or may be controlled manually. .

  Each member of the manufacturing apparatus 1 may be formed of a material having a certain level of strength, and examples of such a material include various resins and various metals. Each member can be produced by a known method such as molding, rolling, and grinding.

  Hereinafter, an example of the manufacturing method according to the present invention using the manufacturing apparatus 1 (hereinafter, sometimes referred to as one manufacturing method according to the present invention) will be described. In one manufacturing method according to the present invention, the steps A to G are performed, and the tubular male connector 52 including the tubular elastic member 54 and the connecting member 55 is attached to one end of the long body 51. This is a featured manufacturing method. 5 to 8, for the sake of convenience, the extension direction on the small diameter portion 16 side of the middle shaft body 11 is referred to as an upper direction or a front end direction, and the extension direction on the large diameter portion 14 side is referred to as a lower direction or a rear end direction.

  In one manufacturing method according to the present invention, first, the process A is performed to place the manufacturing apparatus 1 in an initial state. That is, as shown in FIG. 1 and FIG. 5A, the middle shaft body moving means 41, the tube body moving means 42, and the regulating member 10 are relatively moved forward and backward along the direction of the axis C, respectively. The tube body 12 with the outer diameter changing portion 15 protruding from the opening is arranged in a state protruding from the through hole 18 of the regulating member 10. Specifically, the tubular body 12 is caused to penetrate the regulating member 10 having the regulating surface 19 formed around the through hole 18 through which the tubular body 12 penetrates, and the tubular body 12 protrudes from the through hole 18. The middle shaft body 11 having the outer diameter changing portion 15 whose outer diameter gradually decreases toward the tube is inserted into the tube body 12 so that the outer diameter changing portion 15 protrudes from one opening of the tube body 12. At this time, the restricting member 10 is disposed and fixed at a position corresponding to the axial length of the tubular elastic member 54 covering the tubular body 12. In this example, the restricting member 10 is disposed at the same position as the axial length of the tubular elastic member 54. Has been. Further, the distal end of the tube body 12 and the distal end portion of the large diameter portion 14 (not shown in FIG. 5A) are substantially flush with each other, and the outer diameter changing portion 15 and the small diameter portion 16 protrude from the distal end of the tube body 12. ing.

  Before or after the step A or simultaneously, the pushing member 20 is disposed at a distance from the middle shaft body 11 and the like above the axis C. The initial state of the pushing member 20 is pushed so that the first pushing arm 21A and the second pushing arm 21B are substantially parallel to each other, as shown in FIGS. Suspended by the advancing member moving means 44, the center of the penetrating portion 27 is located substantially on the axis, and the center of the space formed by the first guided portion 37A and the second guided portion 37B is substantially the same as that of the guiding member 31. Located on the axis. In the initial state, the pushing member 20 is in contact with or slightly spaced from the end surface of the first tip member 25A and the end surface of the second tip member 25B, as well shown in FIGS. Oppositely, the opening amount of the penetrating portion 27 is minimized.

  In the manufacturing method according to the present invention, the process B of inserting and arranging the tubular elastic member 54 in the outer diameter changing portion 15 protruding from the opening is then performed. In this example, the tubular elastic member 54 is inserted and disposed in a part of the small diameter portion 16 and the outer diameter changing portion 15. As shown in FIG. 5 (b), the tubular elastic member 54 has an end portion where the third shaft hole 64 is opened on the outer shape changing portion 15 side, and an end portion where the first shaft hole 62 is opened is the pushing member 20. It is inserted so that it is on the side. At this time, since the small diameter portion 16 has an axial length longer than that of the tubular elastic member 54, as shown in FIG. 5B, the small diameter portion 16 penetrates the shaft hole 61 and the end surface of the tubular elastic member 54. Protruding from. And the tubular elastic member 54 is arrange | positioned in series with the pipe body 12 so that it may become substantially coaxial with a space | interval. The insertion and placement of the tubular elastic member 54 may be performed manually or automatically by a tubular elastic member handling mechanism such as a robot arm.

  In the manufacturing method according to the present invention, the tubular elastic member 54 is then pushed relatively toward the tube body 12 along the axial direction of the middle shaft body 11 and expanded at the outer diameter changing portion 15. Step C for sheathing the tubular body 12 is performed. Specifically, the pushing member 20 is relatively advanced along the axis C direction downward. In this example, the middle shaft body moving means 41, the tube body moving means 42 and the regulating member 10 are fixed and the pushing member 20 is advanced. Then, as shown in FIG. 5C, the first tip member 25 </ b> A and the second tip member 25 </ b> B of the pushing member 20 come into contact with the upper end surface of the tubular elastic member 54. At this time, the end surface of the tubular elastic member 54 abuts on the first abutting portion 23A of the first pushing portion 22A and the second abutting portion 23B of the second pushing portion 22B, and the small diameter portion 16 has the penetrating portion 27. Has entered. Further, the small diameter portion 36 of the guide member 31 enters the space portion formed by the first guided portion 37A and the second guided portion 37B.

  When the pushing member 20 is further advanced in the same direction, the tubular elastic member 54 is pushed toward the tube body 12 while being inserted into the outer diameter changing portion 15 as shown in FIG. . As the tubular elastic member 54 is pushed toward the tube body 12, the tubular elastic member 54 slides on the outer peripheral surface of the outer diameter changing portion 15, and the inner diameter, that is, the shaft hole 61 and the outer diameter are gradually expanded. At this stage, as shown in FIG. 6A, since the first tip member 25A and the second tip member 25B have not reached the outer diameter changing portion 15, the first push of the push member 20 is performed. The arm 21 </ b> A and the second pushing arm 21 </ b> B maintain an initial state, that is, a substantially parallel state by the expansion / contraction member 33.

  As shown in FIG. 6B, when the pushing member 20 is further advanced in the same direction and the first tip member 25A and the second tip member 25B reach the outer diameter changing portion 15, immediately before or simultaneously. The opening amount adjusting means 30 causes the first pushing arm 21A and the second pushing arm 21B to move away from each other in the opposite directions with respect to the shaft body pivotally supported by the bearing of the pushing member moving means 44. To turn. That is, when the first guided portion 37A and the second guided portion 37B reach the guide outer diameter changing portion 34 of the guide member 31 and advance along the guide outer diameter changing portion 34, the first guided portion 37A and the second guided portion 37A The space portion formed by the guided outer diameter changing portion 34 is gradually expanded by the guided outer diameter changing portion 34, and the guided portion 37 </ b> B is separated. Then, the first adjustment arm 32A provided with the first guided portion 37A and the second adjustment arm 32B provided with the second guided portion 37B are similarly separated from each other, and the first pressing arm combined with the first adjustment arm 32A is provided. Similarly, the advance arm 21A and the second push arm 21B to which the second adjustment arm 32B is coupled are separated from each other. Then, as the pushing member 20 advances downward, the space portion is gradually and greatly expanded by the inclination ratio of the guide outer diameter changing portion 34. As a result, the penetrating portion 27 is not in contact with the outer surface of the middle shaft body 11 in accordance with the relative position of the pushing member 20 along the axis C direction, and the inclination ratio of the outer diameter changing portion 15 of the middle shaft body 11 The diameter is expanded according to

  In this way, the first pushing arm 21A and the second pushing arm 21B are separated from each other, and as shown in FIG. 6B, the pushing member 20 includes the penetrating portion 27, the outer diameter changing portion 15, and the like. While maintaining the non-contact state, the tubular elastic member 54 is pushed to the tube body 12 side.

  When the pushing member 20 is further advanced in the same direction, as shown in FIG. 6C, the first pushing arm 21A and the first pushing arm 21A according to the relative position of the pushing member 20 along the axis C direction. While being separated from the second pushing arm 21 </ b> B, the tubular elastic member 54 is pushed until the lower end of the tubular elastic member 54 contacts the restriction surface 19 of the restriction member 10, and the tubular elastic member 54 is attached to the outer peripheral surface of the tubular body 12. That is, it is packaged. At this time, since the tubular elastic member 54 completely covers the outer peripheral surface of the tube body 12 and is expanded in diameter, the tube body 12 is pressed by the elasticity in the central axis direction of the substantially uniform axis C in the circumferential direction. Thus, the tube 12 is in close contact with the tube body 12. Thereafter, as shown in FIG. 7A, the pushing member 20 moves backward in the direction of the axis C, enters an initial state, and stands by.

  In the manufacturing method according to the present invention, the process D for removing the central shaft body 11 inserted through the tubular body 12 from the tubular body 12 is then performed. Although not shown, specifically, the tubular body moving means 42 and the regulating member 10 are fixed, and the middle shaft body moving means 41 is moved backward relatively along the direction of the axis C, whereby the middle shaft body 11 is moved to the axis C. Downward in the direction, in other words, the tubular elastic member 54 is moved backward relative to the tube body 12 in the direction of the outer sheath relative to the tube body 12. After the small-diameter portion 16 is completely removed from the tube body 12, the middle shaft body moving means 41 is moved backward relative to the radial direction of the axis C to retract or retract the middle shaft body 11 in the radial direction of the axis C. . When the process D is completed in this manner, as shown in FIG. 7A, the tube body 12 is hollow, and a space for disposing the holding shaft body 13 is provided below the tube body 12. Defined.

  In the manufacturing method according to the present invention, as shown in FIG. 7 (b), the elongated body 51 is then inserted into the tube body 12 from which the middle shaft body 11 is pulled out to form a cavity. The process E which inserts and arrange | positions one edge part is implemented. Specifically, the long body 51 is inserted into the hollow tubular body 12 from the starting direction side of the tubular elastic member 54 in the pushing direction, that is, the upper side, and is inserted into the tubular body 12. In this example, as shown in FIG. 7 (b), the long body 51 is moved to a position where the region where the first bulging portion 67 can be accommodated remains substantially beyond the center of the axis of the tubular body 12. Interpolate to At this time, since the diameter of the tubular body 12 is substantially the same as the outer diameter of the long body 51, the long body 51 inserted and disposed in the tubular body 12 maintains its insertion and arrangement state. In addition, in order to hold | maintain the insertion arrangement state of the elongate body 51 more correctly as needed, the elongate body 51 is hold | maintained using the holding tool which clamps the elongate body 51 from the radial direction, for example, a clamp. It can also be held. The insertion and placement of the long body 51 may be performed manually or automatically by a long body handling mechanism such as a robot arm.

  In one manufacturing method according to the present invention, before or after Step F, which will be described later, that is, before or after Step D, before or after Step E, or between Step D and Step E, As shown in FIGS. 7B and 7C, the holding shaft body 13 is disposed below the tube body 12 while the connection member 55 is held upright in the shaft hole 17 of the holding shaft body 13. . At this time, as shown in an enlarged view in FIG. 7C, the connection member 55 includes a part of the second bulging portion 69 and the flange portion 68 accommodated in the shaft hole 17, and the outer peripheral surface of the flange portion 68 is a shaft. By being in contact with the inner peripheral surface of the hole 17, the first bulging portion 67 is stably held in an upright state protruding from the tip of the holding shaft body 13 while being substantially coaxial with the holding shaft body 13. In this example, since the first bulging portion 67 of the connecting member 55 has a maximum outer diameter larger than the maximum outer diameter of the second bulging portion 69, it is not accommodated in the shaft hole 17 and is not connected to the connecting member 55. Will never fall.

  The holding shaft body 13 holding the connection member 55 in this way is arranged at a position that coincides with the axis C of the tube body 12 as shown in FIG. The holding shaft body 13 is arranged by advancing the holding shaft body moving means 43 in the radial direction of the axis C.

  In one manufacturing method according to the present invention, as shown in FIG. 8 (a), the holding shaft body 13 is then inserted from the other opening into the tube body 12 in which the middle shaft body 11 is pulled out and becomes a cavity. The process F of inserting and arranging the connecting member 55 held upright in the shaft hole 17 is performed. Specifically, by fixing the tubular body moving means 42 and the regulating member 10 and advancing the holding shaft body moving means 43 along the axis C direction, a long body is formed inside the tubular body 12. The collar portion 68 is internally or inserted from the first bulge portion 67 of the connection member 55 such that the first bulge portion 51 and the first bulge portion 67 face each other. At this time, as shown in FIG. 8A and FIG. 8C, the holding shaft body 13 has an end surface on the second bulging portion 69 side of the flange portion 68 accommodated in the shaft hole 17. The lower end surface of the tubular elastic member 54 sheathed on the tube, in other words, the lower opening of the tubular body 12, that is, until it is substantially flush with the restriction surface 19 of the restriction member 10. The connecting member 55 is inserted and arranged inside the tube body 12. Therefore, the end of the holding shaft body 13 slightly enters the tube body 12.

  In the manufacturing method according to the present invention, the process G is then performed in which the tubular body 12 is moved backward relative to the regulating member 10 while regulating the displacement of the tubular elastic member 54 by the regulating surface 19. Specifically, as shown in FIG. 8B, the regulating member 10 and the holding shaft body moving means 43 are fixed and the tube body moving means 42 is moved backward along the axis C direction, The tubular body 12 is removed from the tubular elastic member 54. Then, the tube body 12 moves backward in the same direction against the adhesion force of the tubular elastic member 54. At this time, since the end portion of the tubular elastic member 54 sheathed on the tubular body 12 is in contact with the restriction surface 19 of the restriction member 10, the tubular elastic member 54 cannot be retracted together with the tubular body 12. The connecting member 55 remains in the position where it is inserted into the tube body 12. That is, the tubular body 12 is retracted in the same direction without displacement of the positions of the tubular elastic member 54, the long body 51, and the connecting member 55 arranged via the tubular body 12.

  When the tubular body moving means 42 is moved backward in this way, the tubular elastic member 54 having an inner diameter smaller than the outer diameter of the long body 51 is retracted from the tubular body 12 as shown in FIG. Since it is going to return to the original shape (particularly the original dimension) from the portion by the elastic force, the long body 51 arranged inside the tubular elastic member 54 is arranged in the central axis direction of the axis C substantially uniform in the circumferential direction thereof. It adheres with the elasticity of. Subsequently, when the tubular body moving means 42 is moved backward in the same direction, for example, as shown in FIG. 12, the tubular elastic member 54 comes into close contact with the elongated body 51 as described above, and the tubular elastic member 54 The first bulging portion 67, the shaft 61, and the flange portion 68 of the connection member 55 disposed inside are accommodated in the first shaft hole 62, the second shaft hole 63, and the third shaft hole 64, and the connection member 55 is inserted. To do.

  In this manner, the tubular male connector 52 composed of the tubular elastic member 54 and the connection member 55 can be easily and at once attached to one end of the long body 51.

  As described above, in the manufacturing method according to the present invention, the tubular elastic member 54 does not pass through the tubular body 12, in other words, is folded back on the tubular body 12 and attached to the long body 51. . The magnetic necklace 50 manufactured in this way is taken out from the manufacturing apparatus 1. The step of taking out the magnetic necklace 50 may be carried out manually or automatically by a long ornament taking-out mechanism such as a robot arm.

  In the manufacturing method according to the present invention, as shown in FIG. 5A, the tube body 12, the middle shaft body 11, the holding shaft body 13, the moving means 40, and the regulating member 10 are then returned to the initial state. .

  In one manufacturing method according to the present invention, the magnetic necklace 50 having the tubular male connector 52 attached to the end can be manufactured in this way. In order to manufacture a plurality of magnetic necklaces 50, a series of steps shown in FIGS. 5A to 8B are repeatedly performed.

  In one manufacturing method according to the present invention, by performing the following process G from process A, one end of the long body 51 is inserted into the tubular elastic member 54 sheathed by the tubular body 12 via the tubular body 12. And the connecting member 55 are arranged so as to oppose each other, and the tubular body 12 can be removed while maintaining this arrangement state. Therefore, a tubular male mold comprising the tubular elastic member 54 and the connecting member 55 is provided. The connector 52 can be constructed and attached to one end of the elongated body 51 at the same time. Therefore, according to the manufacturing method according to the present invention, the magnetic necklace 50, which is an example of a long decorative article provided with the tubular male connector 52 at the end, can be manufactured easily and at once.

  Hereinafter, another example of the manufacturing method according to the present invention using the manufacturing apparatus 1 (hereinafter, another manufacturing method according to the present invention may be referred to) will be described. In another manufacturing method according to the present invention, the following process G is performed from the process A, or before or after the process A is performed before or after the process, and the tubular male connector 52 is connected to the long body 51. The tubular elastic female connector 53 is attached to the other end of the long body 51 at the same time as or before or after the attachment to one end of the long body 51. 5 to 10, for the sake of convenience, the extension direction on the small diameter portion 16 side of the central shaft body 11 is referred to as the upper or front end direction, and the extension direction on the large diameter portion 14 side is referred to as the lower or rear end direction.

  In another manufacturing method according to the present invention, a method of performing the process A from the process A after performing the following process G from the process A will be described. Therefore, in another manufacturing method according to the present invention, the long body 51 in which the tubular male connector 52 is attached to one end by performing the following process G from the process A as described above is used. .

  In another manufacturing method according to the present invention, first, process a is performed and the manufacturing apparatus 1 is placed in an initial state. That is, as shown in FIG. 1 and FIG. 5A, the tube body 12 in which the outer diameter changing portion 15 protrudes from one opening is regulated in the same manner as in step A of the manufacturing method according to the present invention. It arrange | positions in the state protruded from the through-hole 18 of the member 10. FIG. Further, in the same manner as in the manufacturing method according to the present invention, the pushing member 20 is arranged at a distance from the middle shaft body 11 and the like in the upper direction in the axis C direction, before or after the step A.

  In another manufacturing method according to the present invention, as shown in FIG. 5 (b), the outer diameter changing portion projecting from the opening is then performed in the same manner as in step B of the one manufacturing method according to the present invention. Step (i) is performed in which the tubular elastic female connector 53 is inserted and disposed in the position 15. In another manufacturing method according to the present invention, a tubular elastic female connector 53 having the same shape and the same dimensions is used instead of the tubular elastic member 54.

  In another manufacturing method according to the present invention, as shown in FIGS. 5 (c) to 6 (c), a tubular elastic female is then performed in the same manner as in step C of the manufacturing method according to the present invention. A process C is performed in which the mold connector 53 is pushed relatively to the tube body 12 side along the axial direction of the middle shaft body 11 and is externally expanded by the outer diameter changing portion 15 to be sheathed on the tube body 12. In this manner, as shown in FIG. 6C, the tubular elastic female connector 53 is tubular until the lower end of the tubular elastic female connector 53 contacts the restriction surface 19 of the restriction member 10. 12 to the exterior.

  In another manufacturing method according to the present invention, a process D is then performed in which the middle shaft body 11 is retracted relative to the tube body 12. This step D is a step of forming a cavity into which the long body 51 is inserted and arranged inside the tube body 12 by the retracted middle shaft body 11, and is, for example, the same as the step D of the one manufacturing method according to the present invention. Examples include a step of removing the middle shaft body 11 inserted through the tube body 12 from the tube body 12, a step of relatively retracting the tip of the middle shaft body 11 at least into the tube body 12, and the like. In another manufacturing method according to the present invention, a step of relatively retracting the tip of the middle shaft body 11 at least into the tube body 12 is employed as step d.

  Specifically, as shown in FIG. 9A, the middle shaft body 11 is directed downward in the direction of the axis C, in other words, in the direction of the outer sheath relative to the tube body 12 of the tubular elastic female connector 53. To at least relatively recede into the tube body 12. In this example, the tip restricting portion 16 a of the middle shaft body 11 is relatively retracted at least into the tube body 12 to form a cavity in the tip direction of the tube body 12. Specifically, the regulating member 10 and the tube body moving means 42 are fixed, and the middle shaft body moving means 41 is retracted downward. At this time, the retraction amount of the tip restricting portion 16a is appropriately adjusted according to the attachment state of the long body 51 to the tubular elastic female connector 53. In the magnetic necklace 50, the tip restricting portion 16a of the middle shaft body 11 is adjusted. As shown in FIG. 9 (a), the tube body 12 is retracted to a position beyond the approximate center of the axis of the tube body 12.

  In another manufacturing method according to the present invention, next, as shown in FIG. 9 (b), the middle shaft body 11 is pulled out into a cavity in the same manner as in step E of the one manufacturing method according to the present invention. The step o of inserting and arranging the other end of the long body 51 from one of the openings into the inside of the tubular body 12 is performed. In this example, as shown in FIG. 9B, the other end of the long body 51 to which the tubular male connector 52 is not inserted from the pushing direction starting side is the tip regulating portion 16a. The long body 51 is inserted into the tube body 12 until it comes into contact with the tube body 12. At this time, the insertion amount of the long body 51 into the tube body 12 is basically the same as the retraction amount of the middle shaft body 11 or the tip regulating portion 16a in the tube body 12. When the long body 51 is inserted and arranged in the tube body 12 in this manner, the displacement of the long body 51 in the direction of the axis C is restricted by the tip restricting portion 16a and the direction other than the direction of the axis C is restricted. The displacement is regulated by the tube body 12 and held so as to be in a desired insertion state. In addition, the long body 51 can also hold | maintain the long body 51 using the said holder similarly to the process E of the one manufacturing method which concerns on this invention.

  In another manufacturing method according to the present invention, in the same manner as in step G of the one manufacturing method according to the present invention, the regulating member 10 while regulating the displacement of the tubular elastic female connector 53 at the regulating surface 19. The process of retracting the tubular body 12 relatively is performed. Specifically, as shown in FIG. 10 (a), the restricting member 10 and the middle shaft body moving means 41 are fixed, and the tube body moving means 42 is moved backward along the direction of the axis C to move the pipe. The body 12 is removed from the tubular elastic female connector 53. Then, the tube body 12 is retracted in the same direction against the adhesion force of the tubular elastic female connector 53. At this time, since the end portion of the tubular elastic female connector 53 sheathed on the tubular body 12 is in contact with the regulating surface 19 of the regulating member 10, the tubular elastic female connector 53 retreats together with the tubular body 12. However, it remains in the position where it was put on the tube body 12. That is, the tubular body 12 is retracted in the same direction without displacement of the positions of the tubular elastic female connector 53 and the long body 51 arranged via the tubular body 12.

  When the tubular body moving means 42 is moved backward relatively in this manner, as shown in FIG. 10A, the tubular elastic female connector 53 having an inner diameter smaller than the outer diameter of the long body 51 is Since the tubular body 12 tries to return to the original shape (particularly the original dimensions) by the elastic force from the retracted portion, the long body 51 arranged inside the tubular elastic female connector 53 is substantially in the circumferential direction. The contact is made with elasticity in the direction of the central axis of the uniform axis C. Subsequently, when the tubular body moving means 42 is moved backward in the same direction, the tubular elastic female connector 53 is attached to the long body 51 as described above, as shown in FIG. Is done.

  In this manner, the tubular elastic female connector 53 can be easily attached to the other end of the long body 51.

  Thus, in another manufacturing method according to the present invention, the tubular elastic female connector 53 does not pass through the tube body 12, in other words, moves back on the tube body 12, so that the long body 51 is attached. The magnetic necklace 50 thus manufactured is taken out from the manufacturing apparatus 1. The step of taking out the magnetic necklace 50 may be carried out manually or automatically by a long ornament taking-out mechanism such as a robot arm.

  In another manufacturing method according to the present invention, as shown in FIG. 5A, the tube body 12, the middle shaft body 11, the moving means 40, and the regulating member 10 are then returned to the initial state.

  In another manufacturing method according to the present invention, the tubular male connector 52 is attached to one end in this manner, and the tubular elastic female connector 53 is attached to the other end. The necklace 50 can be manufactured. In order to manufacture a plurality of magnetic necklaces 50, as shown in FIGS. 5A to 10B, the process A to the process G and the process A to the process F are repeatedly performed. .

  In another manufacturing method according to the present invention, the tubular body is formed inside the tubular elastic member 54 that is sheathed by the tubular body 12 by performing the above-mentioned process A to the above-mentioned process G and the above-mentioned process A to the above-mentioned process. Since the tubular body 12 can be pulled out while maintaining this arrangement state after one end of the long body 51 and the connecting member 55 are arranged to face each other via 12, the tubular elastic member The tubular male connector 52 composed of the connection member 55 and the connecting member 55 can be constructed and attached to one end of the long body 51 and the tubular elastic female connector 53 can be attached to the long body 51. It can be attached to the other end of the. Therefore, according to another manufacturing method according to the present invention, the magnetic necklace 50, which is an example of a long ornamental product including the tubular male connector 52 and the tubular elastic female connector 53 at the ends, can be easily obtained. And it can be manufactured all at once.

  In one manufacturing method according to the present invention and another manufacturing method according to the present invention, the process A is performed from the process A to the process G, and in addition to these processes, the process A is performed. Despite the simplicity of the process, the relative positions of the tubular elastic member 54 or the tubular elastic female connector 53 arranged through the tubular body 12 and the long body 51 and the connecting member or the long body 51. The relationship can be easily and stably maintained until the manufacture of the long decorative article is completed. In particular, in one manufacturing method and another manufacturing method according to the present invention, each of the steps can be performed by a forward operation of the pushing member 20 and a forward / backward operation of the moving means 40. Since it can be semi-automated or automated by adopting the control means or the like, the tubular male connector 52 and the tubular elastic female connector 53 are mounted on the long body 51 as desired without requiring operator skill. be able to. Therefore, although one manufacturing method and another manufacturing method according to the present invention are simple manufacturing methods, long decorative articles having equivalent quality can be manufactured with high yield. Moreover, one manufacturing method according to the present invention and another manufacturing method according to the present invention do not require the tubular elastic member 54 or the tubular elastic female connector 53 to pass through in the axial direction of the tubular body 12, and the tubular body 12 is not required to pass through. By simply retracting, the tubular elastic member 54 or the tubular elastic female connector 53 can be attached to the long body 51 and the tubular male connector 52 can be constructed all at once. The time required for manufacturing can be shortened.

  On the other hand, since the manufacturing apparatus 1 includes the middle shaft body 11, the tube body 12, the holding shaft body 13, the regulating member 10, the pushing member 20, and the moving means 40, one manufacturing method according to the present invention and the present invention. The tubular elastic member 54 or the tubular elastic female connector 53, the long body 51, and the connecting member or the long body 51, which are preferably used for carrying out another manufacturing method, are arranged via the tubular body 12. Can be easily and stably maintained until the manufacture of the long decorative article is completed. Therefore, according to this manufacturing apparatus 1, it is possible to easily and at once manufacture a long decorative article including the tubular male connector 52 and / or the tubular elastic female connector 53 at the end.

  Moreover, since the manufacturing apparatus 1 includes the opening amount adjusting means 30 and the through portion 27 is not in contact with the outer diameter changing portion 15 during operation, the middle shaft body 11 and the through portion 27 are damaged due to wear or the like. There is no, and demonstrates high durability. Furthermore, as described above, the manufacturing apparatus 1 does not need to pass the tubular elastic member 54 or the tubular elastic female connector 53 in the axial direction of the tube body 12, and therefore the time required for manufacturing the long decorative article. Can be greatly shortened.

  As described above, according to the manufacturing apparatus 1 and another manufacturing method according to the present invention, the long decorative article comprising the tubular male connector 52 and the tubular elastic female connector 53 at the ends. It is possible to achieve the object of providing a long decorative article manufacturing apparatus and a manufacturing method thereof that can be manufactured easily and all at once.

  The apparatus for manufacturing a long decorative article according to the present invention is not limited to the above-described embodiments, and various modifications can be made within a range in which the object of the present invention can be achieved.

  The holding shaft body 13 has the shaft hole 17 having a uniform diameter, but may have an inner wall having substantially the same shape as the connecting member 55 to be inserted. For example, a shaft hole having the same shape as the shaft hole 61 of the tubular elastic member 54 can be formed in the holding shaft body instead of the shaft hole 17. According to the holding shaft body having such a shaft hole, the connecting member 55 can be held in an upright state so that the axis of the connecting member 55 more accurately matches the axis.

  The manufacturing apparatus 1 is an apparatus having one each of the tubular body 12, the intermediate shaft body 11, the pushing member 20, the regulating member 10, and the holding shaft body 13.

Can be installed at once.

  In the manufacturing apparatus 1, the middle shaft body 11 has the small diameter portion 16 and the tip restricting portion 16a. However, in this invention, the middle shaft body may not have at least one of the small diameter portion and the tip restricting portion. Alternatively, the tip surface of the outer diameter changing portion may be the tip restricting portion.

  In the manufacturing apparatus 1, the first pushing arm 21 </ b> A and the second pushing arm 21 </ b> B are directly connected by the telescopic member 33. In the present invention, the first pushing arm and the second pushing arm are: If these are connected in proximity or remotely, they may not be directly connected by the expansion / contraction member. For example, the first adjustment arm and the second adjustment arm are directly connected by the expansion / contraction member, so that the first The push arm and the second push arm may be indirectly connected.

  In the manufacturing apparatus 1, the first through recess 24A and the second through recess 24B have the same amount of recess in the thickness direction of the first tip member 25A and the second tip member 25B. The first penetrating recess and the second penetrating recess may be semi-conical recesses whose recesses become smaller toward the pushing member moving means. Similarly, the first guided portion and the second guided portion may be semi-conical concave portions whose concave amount is reduced toward the pushing member moving means. In addition, the decreasing rate of the recessed amount in these semi-conical concave portions may be the same as or different from the inclination rate in the outer diameter changing portion or the guide outer diameter changing portion.

  In the manufacturing apparatus 1, the middle shaft body moving means 41 in which the middle shaft body 11 is erected, the tube body moving means 42 in which the tube body 12 is erected, and the holding shaft body moving means 43 in which the holding shaft body 13 is erected.

You may provide the holding part.

  As shown in FIGS. 2 and 3, the manufacturing apparatus 1 includes a pushing member 30 having the first pushing arm 21 </ b> A and the second pushing arm 21 </ b> B. The member includes an abutting portion that abuts on an end of the tubular elastic member 54 or the tubular elastic female connector 53 that is inserted and arranged in the outer diameter changing portion, and relatively pushes the tubular elastic member 54 toward the tubular body side. For example, a plate-like member having a through-hole, specifically, “pushing member 5” shown in FIG. 4 of Patent Document 1, and “plier 6” shown in FIG. “Holding member 26” shown in FIG. 30 of Patent Document 1 can be used. In the manufacturing apparatus 1, the first pushing arm 21A and the second pushing arm 21B are rotatably supported by the pushing member moving means 44. In the present invention, For example, at least one of the second pushing arms may be supported by the pushing member moving means so that the penetrating recesses are close to or remote from each other.

  In the manufacturing apparatus 1, the intermediate shaft body 11 and the guide member 31 are manufactured and fixed so that the positions (altitudes) of the outer diameter changing portion 15 and the guide outer diameter changing portion 34 in the axis C direction are different. However, in this invention, the intermediate shaft body and the guide member may be manufactured and fixed so that the positions (altitudes) of the outer diameter changing portion and the guide outer diameter changing portion are the same. In this case, the outer diameter changing portion of the intermediate shaft body and the guide outer diameter changing portion of the guide member have the same inclination ratio and axial length, and further, the penetrating portion, the first guided portion, and the second guided portion. In the guide portion, in particular, the end surfaces on the side of the middle shaft body have the same position (altitude) in the axial direction of the middle shaft body.

  The manufacturing apparatus 1 includes a guide member 31 having a large-diameter portion 35, a guide outer diameter changing portion 34, and a small-diameter portion 36.
