By forming the groove, the contact area between the one-side, other-side lower conveyors 25, 26 (conveyor belt 30) and the belt-like rubber member 13 is changed to the one-side, other-side upper conveyors 39, 40 (conveyor belt 44). Although it is smaller than the contact area with the belt-like rubber member 13, in this invention, one side, the other side lower conveyors 25, 26 (conveyor belt 30) and one side, the other side upper conveyors 39, 40 (conveyor belt 44) The material may be made different, or the surface roughness (the degree of unevenness) may be made different. In the present invention, a thin plate-like separator is positioned between the belt-shaped rubber member 13 and the downstream end of the lower conveyor 25, 26 (conveyor belt 30) on one side or the other side. By blowing air between the downstream end of the lower side conveyors 25 and 26 (conveyor belt 30) and the belt-like rubber member 13, the belt-like rubber member 13 is moved from one side and the other side lower conveyors 25 and 26 (the conveyor belt 30). It may be made to detach | leave and it may be made to transcribe | transfer to the one side and other side upper conveyors 39 and 40 (conveyor belt 44) by this.

  An upper drive motor 55 is mounted on the support plate 47 behind the lower drive motor 48, and an upper pulley 56 fixed to the output shaft of these upper drive motors 55, and one side and other side upper conveyors 39, 40. A belt 58 is stretched between the upper pulley 57 fixed to the rear roller 43, and as a result, the upper drive motor 55 is operated to rotate the upper pulley 56 between the belt 58 and the upper pulley 57. If it is transmitted to the conveyor belt 44 of the one-side and other-side upper conveyors 39, 40, the conveying section located below the conveyor belt 44 travels forward. At this time, if the upper surface of the band-shaped rubber member 13 made of unvulcanized rubber is adhered to the conveyor belt 44 by adhesive force, the band-shaped rubber member 13 is supported on the wound body 11 while being supported from above by the conveyor belt 44. It is conveyed forward. The above-described upper drive motor 55, upper pulleys 56 and 57, and belt 58 as a whole apply driving force to the one-side and other-side upper conveyors 39 and 40 so that the conveyor belt 44 travels, and the belt-like rubber member 13 is covered. The upper conveyor drive means 59 which conveys toward the rotary body 11 is comprised. Thus, the one side, the belt-like rubber member 13 conveyed forward by the other side lower conveyors 25, 26 is transferred to the one side, the other side upper conveyors 39, 40 as described above, the one side, After being supplied to the other side upper conveyors 39, 40, one side, one side running at the same speed as the other side lower conveyors 25, 26, the front side by the other side upper conveyors 39, 40, deformed or longitudinally It is conveyed without stretching.

The driving force from the common drive motor is transmitted to the one side, other side lower conveyors 25, 26, one side, the other side upper conveyors 39, 40 so that these conveyor belts 30, 44 run at a constant speed. May be. Lower end portions of four guide rails 61 that are separated from each other and extend perpendicularly to the lower frame 27 are fixed to the front end portions of the lower frame 27 constituting the one-side and other-side lower conveyors 25, 26. The slide bearing 62 fixed to the upper frame 41 of the one-side and other-side upper conveyors 39, 40 is slidably engaged. As a result, the one-side and other-side upper conveyors 39 and 40 are moved up and down while being guided by the guide rail 61, so that the one-side and other-side lower conveyors 25 and 26 are maintained parallel to each other and the other-side lower-side conveyors 25 and 26. The distance between the conveyors 25 and 26 and the lower conveyors 25 and 26 on one side and the other side can be changed. Thus, if one side and the other side upper conveyors 39 and 40 can be raised and lowered along the guide rail 61 extending perpendicularly to the lower frame 27, the one side when the one side and the other side upper conveyors 39 and 40 are raised and lowered. The parallelism between the other side upper conveyors 39 and 40 and the one side and the other side lower conveyors 25 and 26 can be easily maintained with high accuracy.

  A central portion of a pair of screw shafts 63 extending in parallel to the guide rail 61 is rotatably supported on the connection plate 60 fixed to the connection beam 19 positioned immediately after the upper drive motor 55, and the lower ends of these screw shafts 63 The part is formed with a male screw. Screw blocks 64 are respectively fixed to the rear end portions of the one-side and other-side upper conveyors 39, 40, and the lower end portions (male threads) of the screw shaft 63 are screwed into these screw blocks 64. A drive motor 65 is attached to the connecting plate 60 on the rear side of the screw shaft 63. Between the pulley 66 fixed to the output shaft of the drive motor 65 and the pulley 67 fixed to the upper end of the screw shaft 63. Belt 68 is stretched over. As a result, when the drive motor 65 operates and the rotation of the output shaft is transmitted to the screw shaft 63 via the pulley 66, the belt 68, and the pulley 67, the screw shaft 63 rotates without moving up and down, As a result, the one-side and other-side upper conveyors 39 and 40 to which the screw block 64 is fixed are moved up and down while being guided by the guide rail 61.

  The guide rail 61, the slide bearing 62, the screw shaft 63, the screw block 64, the drive motor 65, the pulleys 66 and 67, and the belt 68 described above as a whole include the front end of the lower conveyors 25 and 26 on one side and the other side. The one side and the other side including the rear end of the upper conveyor 39, 40 are relatively close to each other, here the one side, the rear side of the other upper conveyor 39, 40 (the whole here) is stationary The front side contacting / separating means 69 is configured to approach and separate the front end portions (here, the whole) of the lower conveyors 25, 26 on one side and the other side. In the present invention, the front side contact / separation means includes a drive motor, a link mechanism or a crank mechanism for converting the rotation of the drive motor into a linear motion, and the same guide rail and slide bearing as described above. Alternatively, the front end portion of the one side or other side lower conveyor may be moved closer to or away from the rear end portion of the one side or other side upper conveyor. And when the belt-like rubber member 13 is being conveyed forward by the one side, the other side lower conveyors 25, 26, the one side, the other side upper conveyors 39, 40 are raised by the front side contacting / separating means 69, A gap larger than the thickness of the belt-like rubber member 13 is formed between the one side, other side lower conveyors 25, 26 and the one side, other side upper conveyors 39, 40.

  After that, when the starting end 13b of the belt-like rubber member 13 is conveyed to the front end of one side, the other side lower conveyor 25, 26, the one side, the other side upper conveyor 39, The rear end portion (overall) of 40 is moved closer to the front end portion (overall) of the lower conveyors 25, 26 on one side. When the leading end of the belt-like rubber member 13 is strongly clamped by the front ends of the lower conveyors 25 and 26 on one side and the other side, and compressed (crushed) by about 0.5 to 1.0 mm in the vertical direction (thickness direction) ,Stop. As a result, the starting end portion of the belt-like rubber member 13 is pressed and transferred with a large adhesive force to the rear end portion of the one-side, other-side upper conveyors 39, 40, whereby the belt-like rubber by the one-side, other-side upper conveyors 39, 40 is transferred. The support of the member 13 becomes strong, and peeling of the belt-like rubber member 13 from the conveyor belt 44 can be effectively prevented.

On the other hand, a support plate 71 slidably contacting the conveyor belt 30 is provided on the inner surface side of the conveyor belt 30 on one side located on the overlapping portion 53 and on the other side lower conveyors 25 and 26. The pressing force (compression force) is reliably transmitted from the other side lower conveyors 25, 26 and the one side, other side upper conveyors 39, 40 to the belt-like rubber member 13, and the belt-like rubber member 13 is reliably compressed by a predetermined amount. Can be transferred. In this way, when the starting end of the belt-like rubber member 13 is transferred to the one side, other side upper conveyors 39, 40, the front side contact / separation means 69 is operated to move the one side, other side upper conveyors 39, 40, The distance between the one-side, other-side upper conveyors 39, 40 and the one-side, other-side lower conveyors 25, 26 is raised until it is substantially equal to the thickness of the belt-like rubber member 13. Thereafter, the lower and upper drive motors 48 and 55 are operated synchronously so that the one side, the other side lower conveyors 25 and 26 and the one side, the other side upper conveyors 39 and 40 travel at a constant speed, and the belt-like rubber at the overlapping portion 53 The member 13 is transferred from one side, the other side lower conveyors 25, 26 to the one side, the other side upper conveyors 39, 40, while the one side, the other side upper conveyors 39, 40 transfers the band-like rubber member 13 after the transfer. It is conveyed toward the front while being supported from above.

  Here, the belt-like rubber member 13 is transferred to the one-side, other-side upper conveyors 39, 40 simply by lightly pressing (contacting) the starting end portion of the belt-like rubber member 13 to the one-side, other-side upper conveyors 39, 40. In such a case, as described above, the operation of compressing the start end portion of the belt-like rubber member 13 by the one side, the other side lower conveyors 25, 26 and the one side, the other side upper conveyors 39, 40 may be omitted. Well, in this case, after the starting end 13b of the belt-like rubber member 13 reaches one side, the front end of the lower conveyor 25, 26 on the other side, the front side contacting / separating means 69 sets the one side, the other side upper conveyors 39, 40 to one side The distance between the lower conveyors 25 and 26 may be lowered until the thickness of the belt-like rubber member 13 is substantially equal. Furthermore, in this invention, you may fix so that the space | interval between one side, an other side upper conveyor, and one side, an other side lower conveyor may become always substantially equivalent to the thickness of a strip | belt-shaped rubber member.

  Here, when fixed as in the latter case, the one side, the other side lower conveyor and the one side, the other side upper conveyor only need to run at a constant speed, and the one side, the other side lower conveyor moves forward. When the belt-shaped rubber member thus conveyed reaches the overlapping portion, it is transferred from the one side, the other side lower conveyor to the one side, the other side upper conveyor. In addition, as described above, the one side and the other side upper conveyor can be moved up and down by the front side contact / separation means 69 so that only the one side and other side upper conveyors 39 and 40 are raised and lowered with respect to the one side and other side lower conveyors 25 and 26. If the rear end of 39, 40 is moved closer to or away from the front end of the lower conveyor 25, 26 on one side, the length in the front-rear direction of the lower conveyor 25, 26 on the other side It is preferable that the length is larger than the length in the front-rear direction of the one-side and other-side upper conveyors 39, 40. The reason is that if the one side, the other side upper conveyors 39, 40, which are smaller than the one side, the other side lower conveyors 25, 26, are raised and lowered, the structure becomes simple and the energy consumption for raising and lowering is reduced. This is because it can be saved.

  In addition, in this invention, while making one side and an other side upper conveyor stand still, raising and lowering a to-be-wound body makes the to-be-wound body approach and separate from the front end part of the other side upper conveyor. In short, it is only necessary that the wound body and the front end of the upper conveyor on one side and the other side can be relatively approached and separated from each other. In the present invention, the upper conveyor on one side and the other side may be moved in parallel (lifted / lowered) instead of being oscillated so that the front end portion thereof approaches and is separated from the wound body. Furthermore, in the present invention, the rotation of the drive motor is transmitted to the pin while decelerating using a gear train composed of an external gear, a bevel gear, or the like, or an eccentric oscillating speed reducer, etc. The other side lower conveyor, the one side, and the other side upper conveyor may be swung integrally.

  The belt-like rubber member 13 supported from the upper side by the one side, other side upper conveyors 39, 40 is wound by the synchronous operation of the one side, other side lower conveyors 25, 26, one side, other side upper conveyors 39, 40. When it is conveyed toward the rotating body 11 and the start end 13b of the belt-like rubber member 13 is conveyed to one side, the front end portion (downstream end portion) of the other side upper conveyor 39, 40, the rear side contacting / separating means 78 is In operation, the one side, other side lower conveyors 25, 26, one side, other side upper conveyors 39, 40 swing integrally downward about the rear end portion (pin 17) of the support frame 18. As a result, the start end 13b of the belt-like rubber member 13 is pressed against the top 12 of the wound body 11 by the front end portions of the one side, other side upper conveyors 39, 40, and the start end portion of the belt-like rubber member 13 is wound. It is transferred to the top 12 of the body 11. In this state, the wound body 11 rotates and the one side, the other side lower conveyors 25, 26, the one side, the other side upper conveyors 39, 40 operate synchronously, and the conveyor belt 30 and the conveyor belt 44 are wound. When traveling at the same speed as the peripheral speed of the body 11, the belt-like rubber member 13 is transferred to the one side, the other side lower conveyors 25, 26 on the one side, the other side upper conveyors 39, 40, while being conveyed, It is transferred from the other side upper conveyors 39 and 40 to the wound body 11 and wound around the circumference one after another.
