FIG. 6 is an explanatory view showing a bearing plate, a reel, and a boarding prevention plate.

  The linear material feeding device will be described with reference to FIG.

  The linear material feeding device 1 includes a storage box 10, a shaft 20 stored in the storage box 10, a reel 30 rotatably supported on the shaft 20, and a linear shape wound around the reel 30. It is composed of a pair of (two) climbing prevention plates 40 that are bent along the outer peripheral surface of a material (for example, an optical fiber cable) W and are disposed at opposing positions so as to face the outer peripheral surface. Yes.

  The above-described storage box 10 has a rectangular parallelepiped shape made of paper (for example, made of cardboard), and has an opening 12 for a handle formed on the front surface portion 11S and the back surface portion 11H, which is lower than the opening 13 of the front surface portion 11S. A drawer port 13 through which the linear material W is drawn out is provided at the position. The inner shape of the left and right side surface portions 11L and 11R of the storage box 10 is, for example, a square having a side of 342 mm. An inner flap 14 is provided at the upper end of the front portion 11S and the rear portion 11H of the storage box 10, and an inner flap 15 having an insertion hole 16 at the upper end of the right side portion 11R with the right side portion 11R. In addition, an upper lid 17 having an insertion piece 18 to be inserted into the insertion hole 16 of the right side surface portion 11R at an end corresponding to the right side surface portion 11R is provided at the upper end of the left side surface portion 11L.

  Therefore, after each inner flap 14 is bent inward and the inner flap 15 is bent inward, the insertion piece 18 is bent inward while the upper lid 17 is bent inward, and then inserted into the insertion hole 16. The storage box 10 can be closed.

  The shaft 20 is a paper cylinder and is supported at both left and right ends by a bearing plate 21 having a circular shaft support hole 22 as a center. The length of the shaft 20 is substantially equal to the inner dimensions of the left and right side portions 11L and 11R of the storage box 10, for example, 235 mm. Both bearing plates 21 are formed in a square shape substantially equal to the inner surfaces of the left and right side surface portions 11L and 11R of the storage box 10.

  The reel 30 described above is made of paper (for example, made of cardboard), and has a flange portion 32 formed in a circular shape having a diameter shorter than one side of the bearing plate 21, for example, 330 mm, on both sides of the cylindrical winding drum 31. Yes. A circular insertion hole 33 into which the shaft 20 is rotatably inserted is provided at the center of both flange portions 32. Further, between the flanges 32 and the bearing plate 21, in order to reduce the frictional resistance when the reel 30 rotates and to draw out the linear material W with low tension, it is made of paper having a small outer diameter. A ring 35 (for example, made of cardboard) is arranged. When the shaft 20 is sequentially inserted into the bearing plate 21 (the shaft support hole 22), the ring 35, the reel 30 (insertion hole 33), the ring 35, and the bearing plate 21 (the shaft support hole 22), the two bearing plates 21 The total dimension of the thickness, the thickness of the two rings 35 and the axial length of the reel 30 is substantially equal to the length of the shaft 20.

  The above-described two climbing prevention plates 40 are made of paper (for example, made of cardboard), and the length in the length direction (vertical direction) is an internal dimension (approximately 342 mm) from the bottom 11B of the storage box 10 to the middle flap 14. Longer, for example, 370 mm. Further, as shown in FIG. 2A, the two climbing prevention plates 40 have a width substantially equal to the width between the pair of flange portions 32 of the reel 30 and can be inserted between the flange portions 32. The main body 41 and the both sides of both ends in the length direction of the boarding prevention plate main body 41 are protruded by a dimension substantially equal to the thickness of the flange portion 32 of the reel 30 at right angles substantially perpendicular to the length direction. And provided with projecting portions 44A and 44B that are partly in contact with the outer peripheral surface of the flange portion 32. The projecting portions 44A and 44B are provided so as to project at right angles to the sides on both sides in the vicinity of both end portions in the longitudinal direction (vertical direction) of the boarding prevention plate 40. Note that the protrusion on the other end side (lower end side) of the climbing prevention plate 40 is longer than the length (for example, 50 mm) in the length direction (vertical direction) of the protruding portion 44A on one end side (upper end side) of the climbing prevention plate 40. The length (for example, 100 mm) in the length direction (vertical direction) of the portion 44B is longer. Further, the boarding prevention plate 40 (the boarding prevention plate body 41) is closer to one end side (upper side) than the central portion in the longitudinal direction, for example, at a position 150 mm from one end (upper end), that is, the upper and lower protrusions 44A, 44B. A bent portion 42 is provided in the width direction (a direction perpendicular to the length direction) between the bent portion 42 and closer to one end than the central portion in the longitudinal direction and between the upper and lower protruding portions 44A and 44B. The part is provided with an opening 43 through which the linear material W is drawn out in correspondence with the outlet 13. Thus, by making the two climbing prevention plates 40 the same shape, it becomes easy to manufacture the climbing prevention plate 40 and can be mounted without considering the front and back surfaces of the climbing prevention plate 40. Easy to install.

  In addition, since the boarding prevention plate 40 arranged opposite to the boarding prevention plate 40 disposed on the side of the drawer outlet 13 (front portion 11S) in the storage box 10 does not need to pass the linear material W drawn from the reel 30, As shown in FIG.2 (b), the thing without the opening part 43 may be sufficient.

  Next, assembly will be described.

  First, the reel 30 around which the linear material W is wound is rotatably supported by using the shaft 20, the bearing plate 21 and the ring 35, and is bent by the bending portion 42 so that one end side is brought close to one end side. The two climbing prevention plates 40 are accommodated in the storage box 10 in a state of facing each other along the outer peripheral surface of the linear member W wound around the reel 30. Then, when the storage box 10 is covered and closed in order to keep the two climbing prevention plates 40 bent along the outer peripheral surface of the wire W wound on the reel 30, FIGS. As shown in FIG. 3, the over-travel prevention plate 40 on the other end side (lower side) of the bent portion 42 abuts against the inner surfaces of the front surface portion 11S and the back surface portion 11H, and the other end (lower end) of the over-travel prevention plate 40 is the bottom portion 11B. And one end (upper end) of the boarding prevention plate 40 abuts on the inner surface of the intermediate flap 14.

  In this way, when the two climbing prevention plates 40 are accommodated in the housing box 10 together with the reels 30, the climbing prevention plate main body portions 41 located on both sides of the bent portion 42 enter between the flange portions 32 of the reel 30, and the bent portions. The boarding prevention plates 40 on the upper side of 42 approach each other, and a part of the four projecting portions 44 </ b> A and 44 </ b> B comes into contact with the outer peripheral surface of the flange portion 32. In this combined state, the clearance (clearance) between the both side portions of the climbing prevention plate main body portion 41 and the both flange portions 32 of the reel 30 is held in a minute gap where the linear material W does not protrude outside. The length from the inner surface of the bottom portion 11B of the storage box 10 to which the other end of the boarding prevention plate 40 abuts to the bent portion 42 of the boarding prevention plate 40 is the housing box 10 to which the other end of the boarding prevention plate 40 abuts. It becomes longer than the length from the inner surface of the bottom 11B to the center of the reel 30. Therefore, the overpass prevention plate 40 does not move in the storage box 10 and the expected function of the overpass prevention plate 40 can be maintained. Further, since the length in the length direction of the protrusion 44B is made longer than the length in the length direction of the protrusion 44A, the protrusion 44B is brought into contact with the outer peripheral surface of the flange portion 32 and the overpass prevention plate 40 is tilted. Therefore, the intended function of the boarding prevention plate 40 can be maintained.

  Next, the drawing out of the linear material W will be described.

  First, when the linear material W led out to the outside of the storage box 10 through the opening 43 of the boarding prevention plate 40 and the outlet port 13 of the storage box 10 is pulled out from the reel 30 for a predetermined length, the reel 30 is turned clockwise in FIG. Since it rotates, the linear material W can be pulled out from the linear material feeding device 1.

  When the linear material W is pulled out for a predetermined length in this way, the reel 30 is overrun, so that the linear material W wound around the reel 30 is loosened, and the loose linear material W moves the flange portion 32 of the reel 30. Although it tries to get over, it is bent along the outer peripheral surface of the linear material W, and the linear material W which is loosened by the boarding prevention plate main body portion 41 and the protruding portions 44A, 44B of the opposing boarding prevention plate 40 is the flange portion 32. To prevent (prevent) overcoming. That is, the portion where the linear material W is loosened is accommodated between the linear material W wound around the reel 30 and the boarding prevention plate main body 41. Therefore, even if the reel 30 overruns and the linear material W wound around the reel 30 becomes loose, the loose linear material W does not enter between the flange portion 32 of the reel 30 and the bearing plate 21. Even if the linear material W is temporarily loosened when it is overrun and stopped, the loose linear material W can be easily pulled out.

  In the above-described embodiment, the example in which the shaft 20 is supported by the bearing plate 21 has been described. However, the shaft may be directly provided in the storage box. Moreover, although the linear material W was demonstrated as an optical fiber cable, even if it is linear materials, such as a string and a tube, it functions similarly.
