    The present invention relates to a winding method and apparatus for supplying a belt-like rubber member to the outer surface of a wound body and winding it spirally.

In recent years, for example, Patent Document 1 below has proposed a pneumatic tire manufacturing method and apparatus capable of producing a small lot of various types of pneumatic tires while maintaining high productivity.
JP 2004-136549 A

  In this product, a hard core having the same outer shape as the inner surface of the product tire is rotated, a belt-like rubber member is supplied to the outer side of the hard core, and the inner liner is formed by winding it in a spiral shape. To form an inner bead layer. Next, after knitting a carcass layer on the outer side of the inner liner and inner bead layer, the outer bead layer is molded in the same manner as the inner bead layer, and then the side wall rubber member is wound in a spiral shape to form a sidewall, A belt layer is knitted, and then a tread rubber is formed by spirally winding a belt-shaped rubber member to form a green tire.

  Here, for example, in the formation of the tread rubber as described above, the hard core is rotated around the axis while the extruder is moved in a horizontal plane along the outer surface of the hard core while extruding the belt-shaped rubber member from the extruder. Thus, the belt-like rubber member is supplied to the hard core one after another, and is wound and laminated on the outer surface in a spiral manner. At this time, the outer side in the radial direction of the hard core around which the belt-like rubber member is wound is formed. Since the side surface is curved in a substantially arc shape, the extruder is rotated around the vertical axis as the winding position changes, and the belt-like rubber member is supplied so as to be substantially parallel to the inclination of the hard core at the winding position. Yes.

    Here, it is conceivable to supply rubber in the form of a belt-like rubber member from a conveyor through a hopper into the above-described extruder. In this case, the extruder rotates around the vertical axis, and the hopper of the extruder Is displaced in the circumferential direction with respect to the straight line connecting the conveyor and the extruder, the running direction of the belt-like rubber member is changed while slidingly contacting the hopper.

  When sliding contact occurs in this way, a large tension is applied from the hopper to the belt-like rubber member, so that the belt-like rubber member is greatly stretched in the longitudinal direction. As a result, the cross-sectional area of the belt-like rubber member is reduced. There was a problem of insufficient supply of rubber to the extruder. Further, when the tension is excessive or the belt-like rubber member is caught on the edge of the hopper, the belt-like rubber member may be cut halfway.

  In the present invention, when a belt-like rubber member is supplied to a supply means that can move in a horizontal plane and can rotate about a vertical axis, the winding of the belt-like rubber member that can effectively reduce the tension generated in the belt-like rubber member. It is an object of the present invention to provide a turning method and apparatus.

    The first object is to send a belt-like rubber member from the fixed position on the delivery means to the supply means by the delivery means, and a supply means for receiving the delivered belt-like rubber member at the receiving portion. At the same time, the belt-shaped rubber member is supplied to the rotating wound body while being rotated in the horizontal plane along the outer surface of the wound body and rotated around the vertical axis. And immediately before the belt-shaped rubber member reaches the receiving portion of the supply means, the traveling direction is made substantially parallel to the center line of the receiving portion by the changing means that rolls and contacts the belt-shaped rubber member. It can be achieved by the method of winding the belt-shaped rubber member so changed,

  Second, when the wound body is rotating, supported by a movable table that is movable in a horizontal plane along the outer surface of the wound object, and supported by the movable table so as to be rotatable about a vertical axis. A supply means for supplying a belt-like rubber member to the outer surface of the wound body and spirally winding it; a sending means for sending the belt-like rubber member from a fixed position to a receiving portion of the supply means; and a support for the moving table Change means for changing the travel direction to be substantially parallel to the center line of the receiving portion by rolling and contacting the belt-like rubber member immediately before the belt-like rubber member reaches the receiving portion of the supplying means. This can be achieved by a belt-like rubber member winding device.

  In this invention, immediately before the belt-shaped rubber member reaches the receiving portion of the supply means, the traveling direction is changed so as to be substantially parallel to the center line of the receiving portion by the changing means that rolls and contacts the belt-shaped rubber member. Therefore, when the traveling direction of the belt-like rubber member is changed, no sliding contact or catching occurs, and as a result, the tension of the belt-like rubber member is reduced. As a result, the cross-sectional area of the belt-like rubber member is reduced, and a situation where rubber shortage occurs or a cut occurs in the middle is prevented.

According to the third aspect of the present invention, the traveling direction of the belt-like rubber member can be effectively changed and guided to the receiving portion while the structure is simple.
Furthermore, when the tension in the belt-like rubber member described above is greatly changed and the belt-like rubber member is pulled or loosened, the direction of the belt-like rubber member entering the change means changes variously. If comprised as described in claim | item 4, even if a strip | belt-shaped rubber member approachs into a change means from which direction, this can be reliably guided to a receiving part.

  According to the fifth aspect of the present invention, since the distance between the two vertical guide rollers that are in rolling contact with the belt-like rubber member is increased, the direction change angle at the travel direction changing portion of the belt-like rubber member is reduced. Thereby, the bending stress in the band-shaped rubber member when the direction of the band-shaped rubber member is changed can be reduced.

A bearing 55 is accommodated on the upper surface of the rear end of the bracket 54. A bearing case 56 is fixed. Reference numeral 57 denotes a rotating shaft extending in the vertical direction, the lower portion of which is inserted into the bearing case 56 and rotatably supported by the bearing case 56 via the bearing 55. A square box-like shape is formed at the upper end of the rotating shaft 57. A support box 58 is fixed, and a storage space 60 having a rectangular cross section penetrating in the front-rear direction is formed in the support box 58.

  Reference numeral 61 denotes four vertical guide rollers that are stored in the storage space 60 and extend in the vertical direction. Both ends (upper and lower ends) of the vertical guide rollers 61 in the axial direction are formed on the top wall 58a and the bottom wall 58b of the support box 58, respectively. Each is supported for free rotation. Here, the vertical guide rollers 61 are virtually drawn on the top wall 58a of the support box 58, and are arranged on the vertices of horizontal rectangles extending in parallel to the side wall 58c of the support box 58, respectively. The vertical guide roller 61 includes two vertical guide rollers 61a and 61b located on the upstream side in the running direction of the belt-like rubber member 38, and two vertical guide rollers 61c located on the downstream side in the running direction of the belt-like rubber member 38, 61d.

  When the traveling direction of the belt-like rubber member 38 is changed, the belt-like rubber member 38 is arranged on the left side of the center of the storage space 60 and is separated from the longitudinal direction of the belt-like rubber member 38 by two vertical guide rollers. Rolling contact is made with 61a, 61c or one of the two vertical guide rollers 61b, 61d arranged on the right side of the center of the storage space 60 and separated in the running direction of the belt-like rubber member 38.

  62 are four horizontal guide rollers which are stored in the storage space 60 and are orthogonal to the vertical guide rollers 61. Both ends of the horizontal guide rollers 62 in the axial direction can freely rotate on the side walls 58c of the support box 58. And arranged between the vertical guide rollers 61a, 61b and 61c, 61d. Here, two lateral guide rollers 62a and 62b arranged on the upstream side in the running direction of the belt-like rubber member 38 of the lateral guide roller 62 have both axial ends at the lower ends of the longitudinal guide rollers 61a and 61b. Each of the vertical guide rollers 61a and 61b and the horizontal guide rollers 62a and 62b are arranged so as to form a rectangle (here, a square). become.

As a result, the vertical guide rollers 61c and 61d and the horizontal guide rollers 62c and 62d also form a rectangle (here, a square) as described above. The rectangle formed by the vertical guide rollers 61c and 61d and the horizontal guide rollers 62c and 62d is the same as the rectangle formed by the vertical guide rollers 61a and 61b and the horizontal guide rollers 62a and 62b. They are separated from each other in the traveling direction and are parallel to each other.

  Reference numeral 65 denotes a support block in which a total of eight support blocks are fixed, two at the center of the inner surface of each of the top wall 58a, the bottom wall 58b and the both side walls 58c of the support box 58. The rubber member 38 extends in the traveling direction. Reference numeral 66 denotes eight inclined guide rollers which are stored in the storage space 60 and are inclined at 45 degrees with respect to both the vertical and horizontal guide rollers 61 and 62. The inclined guide rollers 66 are supported at both ends in the axial direction. The block 65 is supported so as to be free to rotate, and is disposed between the vertical guide rollers 61a and 61b, the horizontal guide rollers 62a and 62b, and the vertical guide rollers 61c and 61d and the horizontal guide rollers 62c and 62d.

The rollers 66e, 66f, 66g, and 66h are arranged so as to form a rectangle (here, a square) as a whole, but the two rectangles formed by the inclined guide rollers 66 are the vertical and horizontal guide rollers 61 and 62, respectively. It is a congruent or similar shape to the shape of the rectangle that is rotated by 45 degrees with its center as the axis of rotation. When the above-described inclined guide roller 66 is omitted, the belt-like rubber member 38 may be caught at the intersection of the vertical guide roller 61 and the horizontal guide roller 62. Such a situation can be reliably prevented.

  If the horizontal guide roller 62 and the inclined guide roller 66 are arranged between the vertical guide rollers 61a and 61b and the vertical guide rollers 61c and 61d as described above, the two belt-shaped rubber members 38 are in rolling contact with each other. Since the distance between the vertical guide rollers 61a and 61c or between the vertical guide rollers 61b and 61d is increased, the travel direction changing portion of the belt-like rubber member 38 (deformed into an arc shape at the contact portion with the outer periphery of the vertical guide roller 61). The direction change angle G at the position of the belt-like rubber member 38 is reduced, and the bending stress in the belt-like rubber member 38 when the direction of the belt-like rubber member 38 is changed can be reduced.

  The support box 58 and the support block 65 described above constitute a support frame 69 that is supported by the movable table 32 so as to be rotatable about a vertical axis. The support frame 69 includes the vertical and horizontal guide rollers 61, 62, an inclined guide roller 66 is rotatably supported. Here, the vertical and horizontal guide rollers 61 and 62 and the inclined guide roller 66 described above are supported by the moving base 32 through the support frame 69, and immediately before the belt-like rubber member 38 reaches the hopper 37 of the supply means 45. In this case, the rolling direction of the belt-like rubber member 38 is changed to be substantially parallel to the center line of the hopper 37, here the straight line connecting the center of the hopper 37 and the rotation axis of the extruder 35. The changing means 70 is configured.

  If the changing means 70 is constituted by the vertical and horizontal guide rollers 61 and 62 and the inclined guide roller 66 as described above, the tension in the belt-like rubber member 38 is greatly changed, and the belt-like rubber member 38 is pulled or loosened. Thus, even when the approach direction of the belt-like rubber member 38 to the changing means 70 changes variously, the belt-like rubber member 38 can be reliably guided to the hopper 37 by changing the traveling direction in the above direction. it can.

  Reference numeral 73 denotes a guide roller group provided between the support box 58 and the hopper 37 of the extruder 35. The guide roller group 73 is a plurality of horizontal first guides rotatably supported by the bracket 54. The roller 74 and a plurality of second guide rollers 75 provided on both axial sides of each first guide roller 74 and having a lower end portion rotatably supported by the bracket 54 are configured. The guide roller group 73 guides the belt-like rubber member 38 whose traveling direction has been changed by the changing means 70 to the hopper 37 of the extruder 35 while guiding it.

Next, the operation of the first embodiment will be described.
The belt-like rubber member 38 pulled out from the storage case 49 by the operation of the transport conveyor 50 is sent out from the downstream end 51 (fixed position) toward the hopper 37 of the extruder 35. The running direction of the rubber member 38 is changed by the changing means 70 and is guided by the guide roller group 73, and then received by the hopper 37 of the extruder 35. When the belt-like rubber member 38 is supplied to the extruder 35 in this way, the belt-like rubber member 38 is transferred upward while being heated by the screw 36 and then narrowed from the extrusion head 39 of the extruder 35. It is extruded as a belt-like rubber member 40.

  At this time, while rotating the tire intermediate 18 and the forming drum 11, the belt-like rubber member 40 extruded from the extruder 35 is moved to the tire intermediate by moving the supply means 45 back and forth and right and left integrally with the moving table 32. In this case, the supply means 45 is rotated around the vertical axis so that the belt-like rubber member 40 is attached to the tire intermediate body 18 at the position where the tire intermediate member 18 is attached. Paste it so that it is almost parallel to the inclination of the body 18. Then, by performing such spiral winding a plurality of times, a plurality of belt-like rubber members 40 are laminated on the outer surface (radially outer side surface) of the tire intermediate 18 to form the tread rubber 46.

  When the moving table 32 is located on a straight line M connecting the center in the axial direction of the tire intermediate 18 and the downstream end 51 of the conveyor 50, the extruder 35 has an extrusion head 39 and the hopper 37 has a straight line M. Although it is stopped in a posture positioned above, when the moving table 32 moves to the left side position L on the left side of the straight line M, the extruder 35 rotates clockwise by a predetermined angle as shown by a solid line in FIG. Accordingly, the hopper 37 is displaced in the circumferential direction toward the left side. On the other hand, when the movable table 32 moves to the right side position R on the right side of the straight line M, the extruder 35 moves in the opposite direction as shown by the phantom line in FIG. Since it rotates clockwise by a predetermined angle, the hopper 37 is shifted in the circumferential direction toward the right side.

  Here, when the tension of the belt-like rubber member 38 is within the set range, the belt-like rubber member 38 is near the center of the vertical guide roller 61 in the vertical direction (axial direction) as shown in FIGS. In this case, when the movable table 32 moves to the left position L, the belt-like rubber member 38 moves in the vertical direction of the two vertical guide rollers 61b and 61d installed on the right side. The rolling direction is changed to the substantially square shape while rolling and contacting the central portion, and the traveling direction is changed, and then the hopper 37 of the extruder 35 is supplied.

  On the other hand, when the movable table 32 is moved to the right position R, the belt-like rubber member 38 rolls in contact with the vertical center of the two vertical guide rollers 61a and 61c installed on the left side and the traveling direction changes. After the change, the hopper 37 of the extruder 35 is supplied. Further, when the movable table 32 is positioned on the straight line M, the belt-like rubber member 38 is in contact with the vertical guide rollers 61b and 61d or the vertical guide rollers 61a and 61c while rolling or in contact with them. It is supplied to the hopper 37 of the extruder 35 without contact.

  As described above, when the traveling direction of the belt-shaped rubber member 38 is changed by the vertical guide roller 61, the tension of the belt-shaped rubber member 38 acts on the vertical guide roller 61 that is in contact with the support frame 69. The means 70 rotates about the rotation shaft 57, so that the belt-like rubber member 38 comes into rolling contact with the two vertical guide rollers 61 with substantially equal contact pressure, and the direction change angle G of the belt-like rubber member 38 is minimized. Become. Further, as described above, when the tension of the belt-like rubber member 38 is controlled so as to be always within the set range, the changing means 70 may be constituted by only the four vertical guide rollers 61. In this way, it is possible to guide the hopper 37 effectively by changing the traveling direction of the belt-like rubber member 38 while having a simple structure.

  Here, the tension of the belt-like rubber member 38 described above may change due to fluctuations in the feeding speed of the belt-like rubber member 38 from the conveyor 50, etc., but may be outside the set range. If the tension of the belt-like rubber member 38 increases when the belt-like rubber member 38 is moving, the belt-like rubber member 38 between the conveyor 50 and the changing means 70 is stretched, so that the belt-like rubber member 38 is attached to the inclined guide roller 66c (66g). The running direction is changed while being in rolling contact. On the other hand, when the tension of the belt-like rubber member 38 is reduced, the belt-like rubber member 38 between the conveyor 50 and the changing means 70 is loosened. The traveling direction of the member 38 is changed while being in contact with the inclined guide roller 66b (66f).

  On the contrary, when the tension of the belt-like rubber member 38 increases when the movable table 32 is moved to the right position R, the belt-like rubber member 38 is stretched, so that it travels while being in rolling contact with the inclined guide roller 66d (66h). On the other hand, when the tension of the belt-like rubber member 38 is reduced, the belt-like rubber member 38 is slackened, so that the belt-like rubber member 38 travels while being in contact with the inclined guide roller 66a (66e). The direction will be changed.

  Further, when the tension of the belt-like rubber member 38 increases when the movable table 32 is positioned on the straight line M, the belt-like rubber member 38 is stretched, so that the running direction while rolling and contacting the lateral guide roller 62b (62d). On the other hand, when the tension of the belt-like rubber member 38 is reduced, the belt-like rubber member 38 is slackened, so that the belt-like rubber member 38 rolls and contacts the lateral guide roller 62a (62c) in the traveling direction. Will be changed. Thus, even if the belt-like rubber member 38 enters the change means 70 from any direction due to the change in tension, the change means 70 can reliably guide the belt-like rubber member 38 to the hopper 37.

  As described above, immediately before the belt-like rubber member 38 reaches the hopper 37 of the extruder 35, the changing means 70 that makes rolling contact with the belt-like rubber member 38 causes the running direction of the belt-like rubber member 38 to be approximately the center line of the hopper 37. Since the belt-like rubber member 38 is changed to be parallel, no sliding contact or catching occurs when the running direction of the belt-like rubber member 38 is changed. As a result, the tension of the belt-like rubber member 38 is reduced. As a result, the cross-sectional area of the belt-like rubber member 38 is reduced, and it is possible to prevent a situation where the extruder 35 is short of rubber or is cut in the middle.

    In the above-described embodiment, the tire intermediate 18 supported by the forming drum 11 is used as the wound body. However, in the present invention, a hard core having the same outer shape as the inner surface of the product tire is used. May be. Further, in the above-described embodiment, as the supply unit 45, the extruder 35 and the applicator rolls 43 and 44 that extrude as the belt-shaped rubber member 40 from the extrusion head 39 after the band-shaped rubber member 38 received through the hopper 37 is heated. However, in this invention, you may make it comprise from the sticking roll mechanism which supplies and winds the strip | belt-shaped rubber member supplied from the sending means to a to-be-wrapped body as it is. At this time, the entrance of the belt-like rubber member in the sticking roll mechanism becomes the receiving portion.

  Furthermore, in the above-described embodiment, the conveyor 50 is used as the feeding means. However, in the present invention, the reel around which the belt-like rubber member is wound, and the reel is provided with a rotational driving force to form a belt-like shape from the reel. You may make it comprise the drive mechanism which unwinds a rubber member, and the guide roller group which is installed between the reel and the supply means, and guides the strip | belt-shaped rubber member unwound from the reel. In this case, the position where the belt-like rubber member is detached from the guide roller located on the most downstream side is a fixed position.

  Further, in the above-described embodiment, the tread rubber 46 is configured by spirally winding the belt-shaped rubber member 40. However, in the present invention, the squeegee rubber is configured, or the extruder is used. A reinforcing belt may be configured by supplying a cord and winding a belt-like rubber member coated with the cord in a spiral shape.
