  The cutting device 40 for the string-like member 4 includes a cutting portion 41 and a driving device 42, and is disposed in front of the supply direction P of the string-like member 4 with respect to the supply head 20. Further, the cutting device 40 is arranged on the outer side in the radial direction of the wound body 7 (upper side here) with respect to the string-like member 4 wound around the wound body 7. The cutting part 41 of the cutting device 40 is attached to and supported by the support part 75 of the attachment part 72. The drive device 42 of the cutting device 40 is attached to the protruding portion 74 of the attachment portion 72 and is connected to the cutting portion 41. When the winding of the string-like member 4 around the wound body 7 is finished, the cutting device 40 is driven by the driving device 42, and the cutting unit 41 causes the string between the supply head 20 and the wound body 7. The shaped member 4 is cut.

FIG. 3 is a view showing the cutting device 40 for the string-like member 4 according to this embodiment as seen from the Y direction of FIG.
As illustrated, the cutting unit 41 of the cutting device 40 is scissors and includes a pair of blades (a first blade (upper blade) 43, a second blade (lower blade) 44) and a rotation shaft 45. The first blade 43 is attached to the end portion (here, the lower end portion) of the support portion 75 on the wound body 7 side, and the rotation shaft 45 is attached to the intermediate portion of the support portion 75. The second blade 44 is rotatably attached to the rotation shaft 45 and moves so as to rotate about the rotation shaft 45. The drive device 42 is a piston / cylinder mechanism, and moves the piston rod 47 together with a piston (not shown) in the cylinder 46. The cylinder 46 is rotatably attached to a support piece 76 fixed to the projecting portion 74, and the tip end portion of the piston rod 47 is rotatably attached to the second blade 44.

  The drive device 42 moves the second blade 44 together with the piston rod 47 to drive the cutting portion 41 of the cutting device 40. Thereby, the second blade 44 is separated from the first blade 43 (a position where the string-like member 4 is not cut) (a position indicated by a solid line in FIG. 3) and a second position combined with the first blade 43. (Position to cut the string-like member 4) (position indicated by the dotted line in FIG. 3). The drive device 42 arranges the second blade 44 at the first position when the supply of the string-like member 4 is started and during winding of the string-like member 4. In this state, the string-like member 4 passes through the wound body 7 side of the cutting device 40 while being supplied and wound around the wound body 7 at a position where it does not contact the cutting device 40 (first blade 43). To do.

  At the time of cutting the string-like member 4, the second blade 44 is moved from the first position to the second position by the driving device 42, and the string-like member 4 is cut by the first blade 43 and the second blade 44. At that time, the string-like member 4 is disposed between the first blade 43 and the second blade 44 and is cut at a predetermined angle with respect to the width direction by the first blade 43 and the second blade 44. After cutting the string-like member 4, the drive device 42 moves the second blade 44 from the second position to the first position. Thus, the cutting device 40 is driven by the drive device 42 to cut the string-like member 4.

  When the string-like member 4 is cut by the cutting device 40, the supply head 20 is supplied from the supply position K of the string-like member 4 away from the cutting device 40 by the second moving device 50 (see FIGS. 1 and 2). It moves to the cutting position S of the string-like member 4 closer to the cutting device 40 than the position K. The cutting position S of the string-like member 4 is a position adjacent to the cutting device 40, and the supply head 20 at the supply position K is disposed at a position closer to the wound body 7 than the supply head 20 at the cutting position S. . By moving from the cutting position S to the supply position K, the supply head 20 gradually approaches the wound body 7 while being separated from the cutting device 40. On the other hand, by moving from the supply position K to the cutting position S, the supply head 20 gradually moves away from the wound body 7 while approaching the cutting device 40.

  As the supply head 20 moves to the cutting position S, the string-like member 4 between the supply head 20 and the wound body 7 moves together with the supply head 20 and is displaced in the movement direction of the supply head 20. Thereby, the string-like member 4 is moved away from the wound body 7 to the cutting device 40 and is disposed at a position where it is cut by the cutting device 40. In this state, the supply head 20 stops at the cutting position S, and the cutting device 40 cuts the string-like member 4 between the supply head 20 and the wound body 7. Subsequently, the supply head 20 moves to the supply position K, and the cut front end portion of the string-like member 4 moves together with the supply head 20. When the supply head 20 stops at the supply position K, the front end portion of the string-like member 4 is disposed at the supply start position in the vicinity of the wound body 7. Thus, the second moving device 50 moves the supply head 20 to the supply position K of the string-like member 4 and the cutting position S of the string-like member 4 where the string-like member 4 is cut by the cutting device 40. .

  The second moving device 50 includes a guide part 51 attached to the projecting part 74 of the attaching part 72 and a moving mechanism 52 connected to the supply head 20. The supply head 20 is movably attached to the guide part 51 and is guided by the guide part 51 in a predetermined movement direction R (here, obliquely up and down direction). Further, the supply head 20 moves along the guide portion 51 to the supply position K of the string-like member 4 and the cutting position S of the string-like member 4. The moving mechanism 52 is a piston / cylinder mechanism and moves the piston rod 54 together with a piston (not shown) in the cylinder 53. The cylinder 53 is rotatably attached to the connecting portion 71 of the movable body 70, and the tip end portion of the piston rod 54 is rotatably attached to the supply head 20. The moving mechanism 52 moves the supply head 20 together with the piston rod 54 in the moving direction R.

  By the second moving device 50, the supply head 20 is arranged at the supply position K of the string-like member 4 when the supply of the string-like member 4 is started, and is maintained at the supply position K while the string-like member 4 is wound. At the time of cutting the string-like member 4, the supply head 20 is moved from the supply position K of the string-like member 4 to the cutting position S of the string-like member 4 by the second moving device 50 and arranged at the cutting position S. Accordingly, the string-like member 4 between the supply head 20 and the wound body 7 is displaced toward the cutting device 40. Therefore, the second moving device 50 is also a displacement device that displaces the string-like member 4 by the movement of the supply head 20. In addition to the supply head 20, the second moving device 50, the driving device 42 of the cutting device 40, and the pressing device 60 are attached to the movable body 70 of the first moving device 30. The first moving device 30 moves the supply head 20 in the width direction W of the wound body 7 together with each part of the winding device 10 attached to the movable body 70.

  The pressing device 60 includes two rotatable pressing rollers (first pressing roller 61 and second pressing roller 62) that press the string-like member 4 and a switching device 63 that switches between the pressing rolls that hold the string-like member 4. Similar to the cutting device 40, the first pressing roll 61 and the second pressing roll 62 are disposed in front of the supply direction P of the string-like member 4 with respect to the supply head 20, and the radius of the wound body 7. It is arranged outside in the direction. The cutting device 40 (the cutting unit 41) is disposed between the first pressing roll 61 and the second pressing roll 62, and the first pressing roll 61 is disposed between the supply head 20 at the supply position K and the cutting device 40. The Further, the second pressing roll 62 is arranged in front of the first pressing roll 61 and the cutting device 40 in the supply direction P of the string-like member 4.

  When the winding of the string-like member 4 around the wound body 7 is started, the first pressing roll 61 presses the front end portion of the string-like member 4 supplied from the supply head 20 at the supply position K, and The front end portion of the string-like member 4 is disposed on the appendage 7. By the first pressing roll 61, the front end portion of the string-like member 4 is attached to the winding start position of the wound body 7 and disposed at the winding start position. In this state, the wound member 7 is rotated by the rotating device 3, whereby the string-like member 4 is wound around the wound member 7.

  When the string-like member 4 is cut by the cutting device 40, the second pressing roll 62 presses the string-like member 4 wound around the wound body 7, and between the supply head 20 and the wound body 7. A portion of the string-like member 4 on the wound body 7 side is held. In this state, when the supply head 20 moves to the cutting position S, the string-like member 4 between the supply head 20 and the wound body 7 moves away from the wound body 7 and is displaced to the cutting device 40. When the string-like member 4 is displaced, the wound body 7 is rotated in accordance with the movement of the supply head 20. Thereby, the string-like member 4 between the supply head 20 and the wound body 7 is prevented from loosening.

  The switching device 63 includes an arrangement member 64 that arranges the first pressing roll 61 and the second pressing roll 62 at predetermined positions, a rotating shaft 65 attached to the support portion 75, and a displacement mechanism 66. The arrangement member 64 has an L shape, is rotatably attached to the rotation shaft 65, and is displaced so as to rotate about the rotation shaft 65. The first pressing roll 61 is rotatably attached to one end portion (tip portion) of the arrangement member 64, and the second pressing roll 62 is rotatably attached to a bent portion of the arrangement member 64.

  The displacement mechanism 66 is a piston / cylinder mechanism and moves a piston rod 68 together with a piston (not shown) in the cylinder 67. The cylinder 67 is rotatably attached to a support piece 77 fixed to the projecting portion 74, and the distal end portion of the piston rod 68 is rotatably attached to the other end portion (base end portion) of the arrangement member 64. The displacement mechanism 66 moves the proximal end portion of the arrangement member 64 together with the piston rod 68 to displace the arrangement member 64. Due to the displacement of the arrangement member 64, the first pressing roll 61 and the second pressing roll 62 move around the rotation shaft 65. By the switching device 63 operated by the displacement mechanism 66, the pressing device 60 moves the first pressing roll 61 and the second pressing roll 62 to a position where the string-shaped member 4 is pressed and a position where the string-shaped member 4 is not contacted. The pressing roll for pressing the string-like member 4 is switched. Further, the pressing device 60 presses the first pressing roll 61 and the second pressing roll 62 attached to the arrangement member 64 respectively against the string-like member 4.

Next, a procedure for manufacturing the tire by winding the string-like member 4 around the wound body 7 by the winding device 10 will be described.
FIG. 4 is a diagram showing a winding procedure of the string-like member 4 of the present embodiment, and shows the winding devices 10 in different states as in FIG.
First (see FIG. 4A), the supply head 20 is moved by the first moving device 30 in the width direction W of the wound body 7, and the supply head 20 is arranged at a position where winding of the string-like member 4 is started. At that time, the supply head 20 is arranged at the supply position K of the string-like member 4 by the second moving device 50. Further, the front end portion of the string-like member 4 protrudes from the supply head 20 and is disposed at the supply start position.

  Subsequently (see FIG. 4B), the first pressing roll 61 is pressed against the front end portion of the string-like member 4 by the pressing device 60. The front end portion of the string-like member 4 is pressed toward the wound body 7 by the first pressing roll 61 and is disposed at the winding start position of the wound body 7. Next, the wound body 7 is rotated to wind the string-like member 4 around the wound body 7. After starting the winding of the string-like member 4 (see FIG. 4C), the pressing device 60 separates the first pressing roll 61 from the string-like member 4, and the first pressing roll 61 and the second pressing roll 62 are separated from the string-like member 4. Place it in a position where it will not touch. In this state, the string-like member 4 is supplied from the supply head 20 arranged at the supply position K of the string-like member 4 toward the wound body 7, and the string-like member 4 is continuously connected to the wound body 7. Wrap. Further, during the winding of the string-like member 4, the first moving device 30 moves the supply head 20 together with the cutting device 40 in the width direction W of the wound body 7, and the winding position M of the string-like member 4 is changed. The width is changed in the width direction W of the wound body 7. The winding position M of the string-like member 4 gradually moves in the width direction W of the wound body 7.

  The winding device 10 supplies the string-like member 4 to the wound body 7 that rotates around the axis, and winds the string-like member 4 around the wound body 7 in a spiral shape. Thereby, a tire structural member is shape | molded by the to-be-wrapped body 7. FIG. When the winding of the string-like member 4 around the wound body 7 is completed (see FIG. 4D), the pressing device 60 presses the second pressing roll 62 against the portion on the rear end side of the string-like member 4. The string-like member 4 is pressed toward the wound body 7 by the second pressing roll 62 and is held by the wound body 7. Next, the second moving device 50 moves the supply head 20 together with the string-like member 4 from the supply position K of the string-like member 4 toward the cutting device 40 (cutting position S). It arrange | positions at the cutting position S (refer FIG. 4E). Thereby, the string-like member 4 between the supply head 20 and the wound body 7 is separated from the wound body 7 and is brought close to the cutting device 40. Further, the string-like member 4 is displaced to the cutting device 40 and disposed at a position where it is cut by the cutting device 40.

  The second moving device 50 moves the supply head 20 to displace the string-like member 4 to the cutting device 40. In this state, the rotation of the wound body 7 is stopped, the cutting device 40 is driven by the driving device 42, and the string-like member 4 displaced to the cutting device 40 is cut by the cutting device 40. Next, the wound body 7 is rotated to wind the string-like member 4 around the wound body 7 up to the rear end. Further, the cutting device 40 is returned to the original state before cutting, and the supply head 20 is moved from the cutting position S to the supply position K by the second moving device 50. Thereafter, the tire 7 is manufactured by combining the member to be wound 7 with another tire constituent member to form a raw tire and vulcanize the raw tire.

  In the present embodiment described above, the string-like member 4 can be easily cut by the cutting device 40 by moving the supply head 20. Moreover, since the cutting device 40 is moved together with the supply head 20, it is not necessary to move the cutting device 40 alone. It is not necessary to move the wound body 7 when the string-like member 4 is wound or when the string-like member 4 is cut. Therefore, the operation | movement relevant to winding of the string-like member 4 can be simplified. Therefore, the string-like member 4 can be wound around the wound body 7 with a simple operation, and the winding efficiency of the string-like member 4 can be improved. As a result, the time required for winding the string-like member 4 can be shortened.
