Abstract

The present invention obviates correction work when changing the configuration of a band-shaped member (12) so as to project in the direction perpendicular to the front and back surfaces by means of the contact part (86a) of a configuration-changing member (configuration-changing arm (86)). Because the winding roller (50) and the configuration-changing member (configuration-changing arm (86)) are supported on the same support (83) and the contact part (86a) of the configuration-changing arm (86) is brought into contact with the band-shaped member (12) as the contact part is moved on the central surface (F) of the winding roller (50) to change the configuration of the band-shaped member (12) so as to project in the direction perpendicular to the front and back surfaces, even if the contact part (86a) is moved when the rotation axis (A) of the winding roller (50) is inclined with respect to the single plane (B), the configuration of the band-shaped member (12) that spans between the body (86a) on which the band-shaped member is being wound and the winding roller (50) is changed while always intersecting with the central surface (F) of the winding roller (50), limiting deviation to the side of the central surface (F) of the winding roller (50) in the axial direction.

Method and apparatus for winding strip member

The present invention relates to a method and an apparatus for winding a belt-like member that winds the belt-like member in a zigzag manner around the outer peripheral surface of the wound body.

Conventionally, in order to suppress belt end separation and reduce the weight of a pneumatic tire, particularly an aircraft radial tire, a narrow belt-like member is folded on the outer peripheral surface of the wound body at both ends of the winding region. It has been proposed to use a ply (belt layer) configured by winding a plurality of times in a zigzag shape for the tire. Here, as a winding device for winding such a belt-shaped member, for example, a device described in Patent Document 1 below has been proposed. In this configuration, a supply unit that supplies a belt-like member to a wound body that can rotate around an axis, and a movable base can be reciprocated in the axial direction of the wound body along the outer peripheral surface of the wound body. And a drive unit that can be moved closer to and away from the wound body and a winding start position of the belt-like member around the wound body, and can rotate about the normal to the outer peripheral surface of the wound body as a central axis A support body supported by the movable base, and a plurality of support members supported by the support body and pressed in a zigzag manner on the wound body by pressing the belt-shaped member against the outer peripheral surface of the wound body during reciprocation. A rotatable winding roller for winding and a support body and the winding roller are integrally rotated about a central axis, and the rotation axis of the winding roller includes the axis of the body to be wound, and the winding start position is determined. Repeatedly tilted in the opposite direction with respect to a single plane through Is obtained by a that the rotating part.

Here, when the formation of the ply (belt layer) using the belt-shaped member winding device as described above is completed, the belt-shaped member is once cut between the winding roller and the wound body, and then molded. The ply is removed from the body to be wound, and thereafter, the work is performed such that the start end portion of the band-shaped member is crimped to the body to be wound and the band-shaped member is wound again around the body to be wound. As an apparatus for processing such a belt-shaped member terminal, for example, a device described in Patent Document 2 below is known. The movable base can be moved in the axial direction of the body to be wound along the outer peripheral surface of the body to be wound, and the drive unit that can be moved closer to and away from the body to be wound, and the movable base. The first fixed body and the second fixed body fixed to be separated from each other, and the belt-shaped member supported by the first fixed body and pressing the belt-shaped member against the outer peripheral surface of the wound body during the movement of the movable base, A rotatable winding roller that is wound a plurality of times around the wound body in a substantially circumferential direction, and a base end portion is supported by the second fixed body so as to be able to swivel around a turning axis parallel to the axis of the wound body, When the winding of the belt-shaped member around the wound body is completed and the movable base, the first fixed body, the second fixed body, and the winding roller are separated from the wound body by the driving unit, the belt is swung and covered. A belt-like member that bridges between the winding body and the winding roller It is provided with a deforming arm that is deformed so as to protrude in a direction perpendicular to the front and back surfaces by the contacted part, and a cutting part that cuts the deformed band-shaped member between the wound body and the winding roller. is there.

Japanese Patent Laid-Open No. 5-131565 JP-A-5-0669498

And in order to process the terminal of the strip | belt-shaped member in the winding apparatus described in the above-mentioned patent document 1, it is possible to apply the terminal processing apparatus described in patent document 2 as it is to this winding apparatus. Then, the deformable arm described in Patent Document 2 is supported by the second fixed body, which is a separate member from the first fixed body on which the winding roller is supported, so that the base end portion can turn. In a state where the rotation axis of the winding roller is inclined at a predetermined angle with respect to a single plane by the rotating part as described in Patent Document 1, the deformable arm described in Patent Document 2 is turned to When the belt-like member bridging between the winding rollers is deformed by the contact portion of the deformable arm, the belt-like member contacting the contact portion of the deformable arm is pushed up in the vertical direction. As a result, the belt-shaped member between the contact portion of the deforming arm and the winding roller moves upward from the lower end of the winding roller inclined at a predetermined angle (as it approaches the contact portion of the deforming arm). The center surface passing through the center in the axial direction and gradually deviating from the center surface perpendicular to the rotation axis of the winding roller in the axial direction may be separated from the outer peripheral surface of the winding roller (the imaginary line in FIG. 7). See Y). After cutting the band-like member in a state where the band-like member is shifted laterally in this way, the winding roller is brought close to the wound body, and the starting end portion of the band-shaped member is pressed against the wound body by the winding roller. However, if the starting end portion of the belt-like member is detached from the outer peripheral surface of the winding roller, the starting end portion of the belt-like member cannot be pressure-bonded to the wound body by the winding roller. However, there is a problem that the work efficiency is greatly reduced because a correction work for accurately winding the start end portion of the belt-shaped member around the outer peripheral surface of the winding roller is required.

An object of the present invention is to provide a method and an apparatus for winding a belt-shaped member that can eliminate the need for a correction work when the belt-shaped member is deformed by the contact portion of the deformable member.

The purpose of this is to first supply a belt-like member to the wound body rotating around the axis, while moving the movable table along the outer peripheral surface of the wound body. While being reciprocated in the direction, the movable base is supported so as to be able to rotate about the normal to the outer peripheral surface of the wound body through the winding start position of the band-shaped member around the wound body as a central axis. The belt-like member is pressed against the outer peripheral surface of the wound body by a rotatable winding roller supported by the support body, and the support body and the winding roller are rotated integrally around the central axis. Then, the belt-like member is wound by repeatedly inclining the rotation axis of the winding roller in a reverse direction with respect to a single plane including the axis of the wound body and passing through the winding start position. Fold the body in a zigzag shape While the step of winding a plurality of times, and when the winding of the belt-shaped member around the wound body is completed, and when the movable base, the support body and the winding roller are separated from the wound body, The winding portion passes through the center in the axial direction of the winding roller while bringing the contact portion of the deformable member supported by the support body into contact with the belt-shaped member that bridges between the wound body and the winding roller. A step of deforming the belt-like member so as to protrude in a direction perpendicular to the front and back surfaces of the belt-like member by moving the roller on a central plane perpendicular to the rotation axis; A step of cutting between the winding roller and the winding roller, and the winding roller is provided with a start end portion of the belt-shaped member cut by bringing the movable base, the support and the winding roller close to the wound body. By the above A step of crimping the winding body, the winding process of the belt-shaped member, characterized in that it comprises a can be achieved.

Second, a supply unit that supplies a belt-like member to a wound body that can rotate around an axis, and a movable base are reciprocated in the axial direction of the wound body along the outer peripheral surface of the wound body. And a drive unit capable of approaching and separating from the wound body, and the outer periphery of the wound body through the movable base through the winding start position of the belt-shaped member around the wound body A support that is supported so as to be rotatable about a normal to the surface as a central axis, and the belt-like member that is supported by the support and presses the belt-like member against the outer peripheral surface of the wound body during the reciprocating motion. A rotatable winding roller that wraps around the outer peripheral surface of the wound body in a zigzag manner, and rotates the support body and the winding roller integrally around the central axis, Rotating axis of winding roller A rotating part that repeatedly inclines in a reverse direction with respect to a single plane that includes the axis of the wound body and passes through the winding start position, and is supported by the support, and the movable base, the support, and the winding When the roller is separated from the wound body by the drive unit, the axial center of the winding roller is in contact with the belt-shaped member that bridges between the wound body and the winding roller. A deformation member having a contact portion that moves through a central plane perpendicular to the rotation axis of the winding roller and deforms the belt-like member in a direction perpendicular to the front and back surfaces of the belt-like member, This can be achieved by a belt-shaped member winding device comprising a cutting portion for cutting the belt-shaped member between the wound body and the winding roller.

According to the present invention, the winding roller and the deforming member are supported by the support that is the same member that can rotate around the central axis, and the center surface of the winding roller is brought into contact with the belt-shaped member while the contact portion of the deforming member is in contact with the belt-shaped member Since the belt-like member is deformed so as to protrude in the direction perpendicular to the front and back surfaces by moving the top, the contact portion of the deformable member moves while the rotation axis of the winding roller is inclined with respect to a single plane. Even then, the belt-like member that bridges between the wound body and the winding roller will be deformed while always intersecting the central surface of the winding roller, and from the central surface of the winding roller to the axial direction side. There is no such thing as shifting. As a result, the starting end of the band-shaped member can be pressure-bonded to the wound body simply by bringing the winding roller close to the wound body after the band-shaped member is cut, so that the operator can start the end of the band-shaped member. The work efficiency is improved because no correction work is required to wind the wire around the winding roller.

The second moving unit 33 moves a winding roller 50 (to be described later) parallel to the axis of the forming drum 11 in a single plane B (here, a horizontal plane) including the axis of the forming drum 11 and passing through the winding start position D. . In the first moving unit 22 and the second moving unit 33 of the present embodiment, the winding roller is moved using a screw shaft. However, in the present invention, a linear motor, a cylinder is used, or These may be moved using a combination of the above-described screw shafts.

1 to 5, a wave gear type first reduction gear 36 called a harmonic drive (registered trademark) is attached to the front side portion of the left and right plates 29, and the first reduction gear 36 is fixed to the left and right plates 29. A cylindrical circular spline as a fixed side having inner teeth on the inner periphery, outer teeth meshing with the inner teeth of the circular spline, a flex spline as an output side that is thin and elastically deformable, and in the flex spline It is composed of a wave generator as an input side having an elliptical cam that is inserted and whose axis extends vertically (perpendicular to the horizontal plane). A swivel plate 37 is supported on the left and right plates 29 so as to be swivelable. The swivel plate 37 is connected to the flexspline of the first reduction gear 36. The lower end of the intermediate member 38 is fixed to the turning plate 37. A horizontal horizontal plate 39 is fixed to the upper end of the intermediate member 38, and a vertical plate 40 extending in the vertical direction is attached to the upper surface of the horizontal plate 39. The swivel plate 37, the intermediate member 38, the horizontal plate 39, and the vertical plate 40 described above constitute a movable table 41 as a whole.

The vertical plate 40 is provided with a second speed reducer 45 composed of a circular spline, flex spline and wave generator similar to the first speed reducer 36, and here the circular spline is fixed. In the present invention, as the first speed reducer 36 and the second speed reducer 45, instead of the wave gear type speed reducer, an eccentric oscillation type differential speed reducer or a planetary gear speed reducer may be used. Good. A hollow hole 46 penetrating the wave generator is formed on the central axis of the second reducer 45, more specifically on the axis of the wave generator of the second reducer 45, and this hollow hole 46 is supplied to the forming drum 11. The belt-like member 12 on the way can pass. Here, the central axis of the second speed reducer 45, that is, the axis of the wave generator, is located in a single plane B (horizontal plane), passes through the winding start position D, and is perpendicular to the vertical plate 40. It extends to. A support plate 47 as a part of a support body extending perpendicularly to the vertical plate 40 is fixed to the surface (front surface) of the flexspline constituting the second reduction gear 45 on the molding drum 11 side. The support plate 47 is located on the central axis of the second speed reducer 45, here, a single plane B (horizontal plane), and passes through the winding start position D of the belt-like member 12 around the molding drum 11, and the molding drum 11 is supported on the movable base 41 via the second reduction gear 45 so that it can rotate around the normal to the outer peripheral surface of 11.

A winding roller 50 whose rotation axis A is orthogonal to the axis of the wave generator of the second reduction gear 45 is rotatably supported at the end (front end) of the support plate 47 on the molding drum 11 side. 50 can reciprocate in the axial direction in a single plane B (horizontal plane) along the outer peripheral surface of the forming drum 11 by the operation of the first moving unit 22 and the second moving unit 33. In the present invention, the single plane B may be an inclined plane inclined at an acute angle with respect to the horizontal plane, or a vertical plane (vertical plane) orthogonal to the horizontal plane. In the present invention, in order to facilitate the position control of the winding roller 50, the front end (winding start position D) of the winding roller 50 is positioned on the vertical axis of the first reduction gear 36. Also good. A drive motor 51 is fixed to the left and right plates 29 directly below the first reduction gear 36. The output shaft of the drive motor 51 is connected to the wave generator of the first reduction gear 36.

As a result, when the drive motor 51 is actuated to transmit the rotation reduced from the flexspline of the first speed reducer 36 to the movable base 41, the movable base 41 is connected to the vertical axis (wave) of the first speed reducer 36. The winding roller 50 supported by the support plate 47 rotates around a vertical axis in a horizontal plane at this time. The drive motor 51 and the first reduction gear 36 described above constitute a swivel unit 54 that swivels the movable base 41 and the winding roller 50 about an axis perpendicular to the single plane B (horizontal plane). Then, while the winding roller 50 supported by the movable table 41 is separated from the outer peripheral surface of the forming drum 11 by a certain distance, the first moving unit 22 and the second moving unit 33 move along the outer peripheral surface of the forming drum 11 in the horizontal plane. Is reciprocated in the axial direction of the forming drum 11, the winding roller 50 is swung around an axis perpendicular to the single plane B (horizontal plane) by the swivel unit 54. In this way, even if the arc portion as described above is formed on the forming drum 11, the tangent to the outer peripheral surface of the arc portion at the winding start position D and the rotation axis A of the winding roller 50 are held in parallel. can do. In the present invention, a worm driven by a motor, a rack and pinion driven by a cylinder, or a link may be used as the turning portion.

The first moving unit 22, the second moving unit 33, and the turning unit 54 described above constitute a drive unit 55 as a whole, and the movable table 41 moves along the outer peripheral surface of the forming drum 11 by operating the drive unit 55. As a result, it can reciprocate in the axial direction of the molding drum 11 while being separated from the outer peripheral surface of the molding drum 11 by a certain distance, and can be moved closer to and away from the molding drum 11. In the present invention, the drive unit 55 includes a guide cam or a guide slit located in the single plane B and extending along the outer peripheral surface of the wound body, and a winding roller, a support body, and a movable base. Or you may use what was comprised from the moving part moved along a guide slit, or may use the articulated industrial robot by which the winding roller was supported by the front-end | tip of a hand. When the wound body is constituted by a cylindrical forming drum, the drive part 55 can be constituted only by the first moving part 22 and the second moving part 33, and the turning part 54 can be omitted.

A pair of regulating rollers 56 extending in the vertical direction is rotatably supported at the end (rear end) of the horizontal plate 39 opposite to the forming drum 11. These regulating rollers 56 are arranged at an equal distance from the width of the belt-like member 12. Then, the belt-like member 12 supplied toward the forming drum 11 passes between the regulating rollers 56 in the middle of the supply, and at this time, both side ends in the width direction of the belt-like member 12 are brought into rolling contact with the regulating roller 56. Thus, the posture of the belt-like member 12 during supply to the forming drum 11 is stabilized. On the upper surface of the horizontal plate 39, a rectangular plate-shaped guide plate 57 extending in the vertical direction is fixed. The guide plate 57 extends perpendicular to the vertical plate 40. A plurality of, here two, guide

rollers

58 and 59 and one regulating roller 60 are supported on the guide plate 57 so as to be rotatable around a horizontal axis, and these

guide rollers

58 and 59 and the regulating roller 60 are supported by the guide plate 57. The running direction of the belt-like member 12 is changed when the belt-like member 12 in the middle of supply rolls in contact with each other.

A fluid cylinder 61 extending in the vertical direction is attached to the guide plate 57 directly below the regulating roller 60. At the tip (upper end) of the piston rod 62 of the fluid cylinder 61, a clamping roller 63 that can contact the regulating roller 60 is rotatably supported. When the piston rod 62 of the fluid cylinder 61 protrudes and the sandwiching roller 63 rises, the sandwiching roller 63 presses the strip-shaped member 12 being supplied to the forming drum 11 against the regulating roller 60, and the strip-shaped member 12 is Clamping from above and below in cooperation with the regulation roller 60. A one-way clutch 64 connected to the regulation roller 60 is attached to the guide plate 57. The one-way clutch 64 permits or prevents the regulation roller 60 from rotating, thereby allowing the belt-like member 12 sandwiched between the regulation roller 60 and the sandwiching roller 63 to travel in the supply direction (forward) with respect to the forming drum 11. On the other hand, the strip member 12 is prevented from traveling in the direction opposite to the supply direction to the forming drum 11 (backward).

As described above, if the one-way clutch 64 allows the belt-like member 12 to travel in the supply direction, but prevents the belt-like member 12 from traveling in the direction opposite to the supply direction, the unwinding portion and the regulating roller 60 Between the festoon and the belt-like member 12 in the air, there is a part that travels in the air, so even if an external force is applied to the belt-like member 12 in the direction opposite to the supply direction (backward), Thus, the belt-like member 12 can be spirally wound around the forming drum 11 quickly and smoothly. The support plate 47 supports at least one guide roller 65 that can freely rotate around a horizontal axis, and here, the guide roller 65 is supported by the belt-like member 12 supplied through the hollow hole 46. Is guided to the lower side of the winding roller 50. The

guide rollers

58 and 59, the regulating roller 60, and the guide roller 65 described above constitute a supply unit 66 that supplies the belt-like member 12 to the forming drum 11 that can rotate around the axis. In the present invention, a transport conveyor may be used as the supply unit, or a combination of a roller and a transport conveyor as described in this embodiment may be used.

When the belt-shaped member 12 is supplied to the molding drum 11 by the supply unit 66 when the molding drum 11 rotates around the axis, the belt-shaped member 12 is pressed against the outer peripheral surface of the molding drum 11 by the winding roller 50. And wound around the outer peripheral surface of the forming drum 11. At this time, the winding roller 50 is driven by the drive unit 55 within a single plane B (horizontal plane) along the outer peripheral surface of the forming drum 11 from the outer peripheral surface of the forming drum 11 (substantially the same as the thickness of the belt-like member 12). Reciprocating in the axial direction of the forming drum 11 while being separated by a distance). On the other hand, the support plate 47 and the winding roller 50 are swung around the vertical axis of the first speed reducer 36 so that the rotation axis A of the winding roller 50 is tangent to the outer peripheral surface of the forming drum 11 at the winding start position D. Displace in parallel.

As described above, when the belt-like member 12 is pressed against the outer peripheral surface of the forming drum 11 by the winding roller 50 during the reciprocating motion of the winding roller 50, the belt-like member 12 is zigzag while being folded at both ends in the width direction of the winding region. The strip member 12 can be wound around the outer peripheral surface of the forming drum 11 a plurality of times. A timing pulley 69 coaxial with the wave generator is connected to the wave generator of the second reduction gear 45. On the axis of the timing pulley 69, a hollow hole 70 is formed which is coaxial with the hollow hole 46 and through which the belt-like member 12 being supplied passes. A drive motor 71 is attached to the horizontal plate 39. A timing belt 75 that passes through a through window 74 formed in the guide plate 57 is stretched between a timing pulley 73 and a timing pulley 69 that are fixed to the output shaft 72 of the drive motor 71.

The timing pulley 69, the drive motor 71, the timing pulley 73, and the timing belt 75 described above constitute a drive unit 76 that applies a rotational driving force to the second speed reducer 45 as a whole. Further, the second reduction gear 45 and the drive unit 76 as a whole apply a rotational driving force to the support plate 47 and the winding roller 50 when the belt-like member 12 is wound, thereby supporting the support plate 47 (a support bracket described later). 82) and the winding roller 50 are integrally positioned within a single plane B (horizontal plane) and pass through the winding start position D of the belt-like member 12 around the forming drum 11. By rotating the normal line with respect to the outer peripheral surface of the forming drum 11 as a central axis, a rotating unit 77 capable of repeatedly tilting the rotation axis A of the winding roller 50 in the opposite direction with respect to a single plane B (horizontal plane). Constitute. The rotating portion 77 can change the inclination angle of the rotation axis A of the winding roller 50 with respect to the single plane B, that is, the roller inclination angle G (see FIG. 7). In the present invention, a rotary actuator or a rack and pinion can also be used as the rotating part.

When the driving motor 71 is operated and the rotational driving force of the driving motor 71 is input to the wave generator of the second reduction gear 45, the low speed rotation is transmitted from the second reduction gear 45 to the support plate 47 and the winding roller 50. As a result, the support plate 47 (a support body 83 constituted by a support bracket 82 to be described later) and the winding roller 50 pass through the winding start position D of the belt-shaped member 12 around the forming drum 11 and the forming drum 11 The axis of rotation of the winding roller 50 is rotated at a predetermined angle with respect to the horizontal plane. As described above, when the rotation axis A of the winding roller 50 is inclined with respect to the horizontal plane, the belt-like member 12 is supplied from the supply unit 66 to the winding roller 50, and the movable base 41, the support plate 47, and the like. While the winding roller 50 is moved in the axial direction along the outer peripheral surface of the forming drum 11 by the drive unit 55, when the forming drum 11 rotates around the axis, the belt-like member 12 is pressed by the winding roller 50 while the forming drum 11 11 is wound spirally around the outer peripheral surface (winding region) in a state inclined with respect to the horizontal plane (see FIGS. 2 and 8). Then, when the belt-like member 12 is wound up to one end in the width direction of the winding region, the belt-like member 12 is wound around the outer peripheral surface of the forming drum 11 by a predetermined length in the circumferential direction as shown in FIG. In this case, the winding roller 50 is gradually inclined by the drive motor 71 so that the crossing angle (roller inclination angle G) between the rotation axis A of the winding roller 50 and the horizontal plane becomes zero.

In this way, by repeatedly inclining the rotation axis A of the winding roller 50 in the opposite direction with respect to the single plane B (horizontal plane), the band-shaped member 12 is formed on the outer peripheral surface of the forming drum 11 with the width of the winding region The circumferential direction portions 12a extending in the circumferential direction are provided at both ends in the direction, and then folded back and wound in a zigzag shape so as to form a wave of approximately two cycles per round. In the present invention, winding may be performed so as to form a wave of approximately one cycle per round. A detection unit 79 composed of a two-dimensional laser sensor or the like is fixed on the upper surface of the swivel plate 37. This detection unit 79 is a circumferential distance between adjacent belt-like members 12 wound around the outer peripheral surface of the forming drum 11, for example, a circumferential length of a gap located between the belt-like members 12, or a width of the belt-like member 12. The circumferential distance between the direction center lines can be detected.

1, 5, 6, and 7, an L-shaped support bracket 82 is fixed to the support plate 47. The support bracket 82 and the support plate 47 constitute a support body 83 as a whole. A drive motor 85 as a drive unit in which the rotation shaft of the output shaft 84 is coaxial with the rotation axis A of the winding roller 50 is attached to the support 83, specifically the support bracket 82. A base end portion of an inner arm 87 constituting a part of a deformable arm 86 as a deformable member is fixed to the output shaft 84 of the drive motor 85. Note that a rotary actuator or a rack and pinion may be used as the drive unit described above. A fluid cylinder 88 as a moving portion extending parallel to the rotation axis A of the winding roller 50 is fixed to the distal end portion of the inner arm 87, and the distal end of the piston rod 89 of the fluid cylinder 88 is fixed to the base of the outer arm 90. The end is fixed.

The inner arm 87 and the outer arm 90 described above constitute a deformable arm 86 as a deformable member as a whole. The outer arm 90 of the deformable arm 86 can be moved in the direction of the rotation axis of the winding roller 50 by the operation of the cylinder 88. In addition, the base end portion of the deforming arm 86 is supported by the support body 83 via the drive motor 85 so as to be able to turn around a turning axis coaxial with the rotation axis A of the winding roller 50. The distal end portion of the deformable arm 86 (outer arm 90) serves as a contact portion 86a that can contact the belt-like member 12. The contact portion 86a moves in the direction of the rotation axis of the winding roller 50 by the operation of the cylinder 88, and moves on an arc centering on the turning shaft by the operation of the drive motor 85. Note that the swivel axis located at the base end of the deformation arm 86 may be offset from the rotation axis A of the winding roller 50 as long as it is parallel to the rotation axis A of the winding roller 50. The arm 86 only needs to be supported by the support 83 so that the base end portion thereof can turn about a turning axis parallel to the rotation axis A of the winding roller 50.

Then, after the winding of the belt-like member 12 to the forming drum 11 is completed, when the movable base 41, the support 83, and the winding roller 50 are separated from the forming drum 11 by the operation of the driving unit 55, the winding roller 50 and the forming drum The belt-like member 12 is bridged almost horizontally between 11 and 11. At this time, the deforming arm 86 turns about the turning axis from the lower side to the upper side by the operation of the drive motor 85, and the contact portion 86a passes through the center in the axial direction of the winding roller 50 and the rotation axis of the winding roller 50 When moving while drawing a circular arc on the central plane F perpendicular to A, in other words, in a state of intersecting the central plane F, the contact portion 86a is lowered to the belt-like member 12 bridged in the middle of turning. Even after this contact, the contact portion 86a continues to move on the center surface F of the winding roller 50 by turning. Therefore, the strip-shaped member 12 being bridged is pushed up by the contact portion 86a of the deformable arm 86 so as to protrude in a direction perpendicular to the front and back surfaces of the strip-shaped member 12 (here, the strip-shaped member 12 The shape is deformed so as to form a convex chevron while exhibiting a triangular shape in the thickness direction. At this time, even if the space between the forming drum 11 and the winding roller 50 is narrow, if configured as described above, the belt-like member 12 that is bridged quickly and reliably is deformed while having a simple structure. Can be made.

In the present invention, when the belt-shaped member is deformed so as to protrude, the contact portion of the deformable member is moved linearly on the center surface F of the winding roller between the wound body and the winding roller. In this case, a fluid cylinder, a screw, or the like may be used as the drive unit described above. Here, at the base end portion and the distal end portion of the outer arm 90,

protrusions

91 and 92 projecting forward in the rotational direction when the winding roller 50 is wound are formed apart from each other in the longitudinal direction. As a result, when the belt-like member 12 bridged as described above is deformed so as to protrude by the contact portion 86a of the deformable arm 86, the deformed belt-like member 12 is stretched between the protrusion 91 and the protrusion 92 in the air. . In the present invention, the roller may be rotatably supported at the tip of the deformation arm 86.

When the fluid cylinder 88 is actuated and the piston rod 89 protrudes, the contact portion 86a of the deforming arm 86 moves in the direction of the rotation axis of the winding roller 50 from the position indicated by the solid line in FIG. Then, it approaches the winding roller 50 and overlaps with the belt-like member 12 located on the center surface F of the winding roller 50, ie, being bridged. On the other hand, when the piston rod 89 is retracted by the operation of the fluid cylinder 88, the contact portion 86a of the deformation arm 86 moves in the direction opposite to the rotation axis of the winding roller 50 to the position indicated by the solid line in FIG. It separates from the attaching roller 50 and is separated from the central surface F of the winding roller 50 laterally, that is, separated from the overlap with the belt-like member 12 being bridged. In the above-described embodiment, the deformable member (the deformable arm 86) is configured by the inner arm 87 and the outer arm 90. However, in the present invention, the deformable member may be configured by an integral object. In this case, the moving member moves the deformation member alone in the rotation axis direction of the winding roller 50, or the deformation member and the drive unit move integrally in the rotation axis direction of the winding roller 50. do it. Moreover, in this invention, you may make it use a screw and a solenoid as a moving part. Further, in the present invention, the base end portion of the outer arm 90 is slidably connected to the distal end portion of the inner arm 87, and the outer arm 90 is swung relative to the inner arm 87 by a moving portion such as a fluid cylinder. The contact portion 86a provided on the outer arm 90 may be positioned on the center surface F of the winding roller or separated from the center surface F to the side.

At one side of the winding roller 50, a cylinder (see FIG. 1) 95 as a moving part extending in parallel with the axis of the forming drum 11 is installed. The cylinder 95 is attached to a fixed frame (not shown) so that its position can be adjusted. A bracket 97 is fixed to the tip of the piston rod 96 of the cylinder 95, and a commercially available air cutter 98 as a cutting portion is attached to the bracket 97. Here, the air cutter 98 moves the piston by supplying and discharging air, and transmits the movement of the piston to the cutting blade 98a to swing the cutting blade 98a like a ridge, thereby forming the belt-shaped member 12. In the width direction at a portion stretched between the drum 11 and the winding roller 50, here, between the contact portion 86a of the deformation arm 86 and the winding roller 50 (specifically, between the protrusion 91 and the protrusion 92). Disconnect. In the present invention, the belt-shaped member at the portion stretched between the wound body and the contact portion of the deformable portion may be cut by the cutting portion. What is necessary is just to cut | disconnect a strip | belt-shaped member between rollers. Here, when the outer diameter of the forming drum 11 is changed, the mounting position of the cylinder 95 with respect to the fixed frame may be changed corresponding to the above-described change. In the present invention, the cutting portion may be constituted by an anvil extending parallel to the axis of the forming drum 11 and a disk-shaped cutter blade that is movable along the anvil and rotates.

In this embodiment, the winding roller 50 and the deformable arm 86 are both supported by the support body 83 that is the same member that can rotate about the central axis, and the contact portion 86a of the deformable arm 86 is formed on the belt-shaped member 12. The belt-like member 12 was deformed so as to protrude in a direction perpendicular to the front and back surfaces by moving on the central surface F of the winding roller 50 while making contact. Therefore, even if the contact portion 86a of the deformation arm 86 moves in a state where the rotation axis A of the winding roller 50 is inclined with respect to the single plane B, a band shape between the forming drum 11 and the winding roller 50 is obtained. As shown by the phantom line X in FIG. 7, the member 12 is deformed while always intersecting the central surface F of the winding roller 50, and may be displaced from the central surface F of the winding roller 50 in the axial direction. It is suppressed.

As a result, the start end of the band-shaped member 12 can be pressure-bonded to the forming drum 11 simply by bringing the winding roller 50 close to the forming drum 11 after the band-shaped member 12 is cut. Correction work such as winding the start end portion around the outer peripheral surface of the winding roller 50 is unnecessary, and the work efficiency is improved. On the other hand, as described in the background art, as indicated by the phantom line Y in FIG. 7, the band-shaped member 12 moves from the lower end of the winding roller 50 toward the upper side and from the central surface F of the winding roller to the axial direction side. Therefore, by simply bringing the winding roller 50 closer to the forming drum 11, the start end portion of the belt-like member 12 cannot be crimped to the forming drum 11 by the winding roller 50. There arises a problem that the operator needs to perform a correction operation for accurately winding the starting end portion of the belt-shaped member 12 around the outer peripheral surface of the winding roller 50.

The fluid cylinder 101 as a moving part is fixed to the bracket 97. The fluid cylinder 101 is inclined so as to approach the forming drum 11 as it goes downward. An application roller 104 extending parallel to the axis of the forming drum 11 is rotatably supported at the tip of the piston rod 102 of the fluid cylinder 101 via a bracket 103. When the fluid cylinder 101 is actuated and the piston rod 102 protrudes, the application roller 104 moves obliquely downward while grazing directly above the contact portion 86a of the deformable arm 86 that has swung to the upper limit, and forms the forming drum 11 and the contact portion 86a. The belt-like member 12 bridged between the belt-like member 12 is pushed obliquely downward in the vicinity of the contact portion 86a (see the phantom line in FIG. 6), so that the belt-like member 12 positioned between the contact portion 86a and the forming drum 11 is obtained. Is displaced (deformed in a convex shape toward the lower side) in a direction perpendicular to the front and back surfaces (in the thickness direction of the belt-like member 12). As a result, the band-shaped member 12 positioned between the forming drum 11 and the winding roller 50, here between the contact portion 86a and the winding roller 50, that is, the position (cutting position) cut by the air cutter 98. Without displacing (deforming) the belt-like member 12, a longitudinal tension is applied to the belt-like member 12 at the position. In the present invention, tension may be applied to the band-shaped member at the cutting position by displacing the band-shaped member between the contact portion and the winding roller by the applying roller.

Thus, if the tension is applied to the band-shaped member 12 at the cutting position by the applying roller 104 immediately before cutting by the air cutter 98, the band-shaped member 12 can be easily and reliably cut. Further, if the applying roller 104 is passed through the vicinity of the contact portion 86a by the fluid cylinder 101 as described above, an appropriate value of tension can be applied to the belt-like member 12 even if the stroke of the fluid cylinder 101 is short. The moving part can be easily downsized. A drive source for driving and rotating the forming drum 11,

drive motors

20, 31, 51, 71, 85, and control signals are output to the

fluid cylinders

88, 101, respectively, and these drive sources, drive

motors

20, 31, 51, 71, 85 The operation of the fluid cylinders 88 and 101 (on, off, rotational speed, etc.) is controlled by a control unit 105 (see FIG. 1) such as a personal computer.

Next, the operation of the embodiment will be described.
In a state where the belt-like member 12 is wound around the outer peripheral surface of the molding drum 11, the molding drum 11 is rotated around the axis by the driving force from the drive source, and the belt-like member 12 unwound from the unwinding portion. Is supplied from the lower side to the outer peripheral surface of the winding roller 50 by the supply unit 66. Here, the winding roller 50 is formed while being separated from the outer peripheral surface of the forming drum 11 by a certain distance (approximately the same distance as the thickness of the belt-like member 12) by the operation of the first moving part 22 and the second moving part 33. While moving (forward movement) in the single plane B (horizontal plane) along the outer peripheral surface of the drum 11 toward one end in the width direction of the winding region, the swivel unit 54 operates around the axis of the first reduction gear 36. The rotation axis A is inclined so as to be parallel to the tangent to the outer peripheral surface of the forming drum 11 at the winding start position D. At this time, the belt-like member 12 supplied to the forming drum 11 while being wound around the winding roller 50 is pressed against the outer peripheral surface of the forming drum 11 by the winding roller 50 at the winding start position D. As a result, the belt-like member 12 is transferred from the winding roller 50 to the periphery of the forming drum 11 (winding region), and is wound spirally while preventing air from entering.

Thus, when the belt-like member 12 is spirally wound around the outer peripheral surface of the forming drum 11, the belt-like member 12 is wound while being inclined at a relatively large angle with respect to the circumferential direction. When the belt-like member 12 is wound around the forming drum 11, the winding roller 50 and the support 83 are integrally rotated around the normal line passing through the winding start position D by the rotating portion 77, thereby winding the winding roller 50. The roller inclination angle G with respect to the single plane B (horizontal plane) of the rotation axis A is adjusted, and the crossing angle between the rolling direction of the winding roller 50 (winding direction of the belt-like member 12) and the single plane B (horizontal plane). Is a predetermined angle. When the winding of the belt-like member 12 reaches one end in the width direction of the winding region, the rotating portion 77 (drive motor 71) winds until the crossing angle between the rotation axis A of the winding roller 50 and the horizontal plane becomes zero. The attaching roller 50 and the support 83 are rotated in a short time. When the winding roller 50 reaches one end in the width direction of the winding area, the operation of the drive unit 55 is temporarily stopped to stop the axial movement of the winding roller 50. At this time, the molding drum 11 is continued. Then, the belt-like member 12 is wound around the end of the winding region in the width direction by a predetermined distance in the circumferential direction. In this way, the boundary between the spiral winding and the circumferential winding of the belt-like member 12 can be continued with an arc having a relatively small radius of curvature, and thereby the belt-like member can be formed without stopping the rotation of the forming drum 11. The member 12 can be continuously wound, and the working efficiency is easily improved.

Next, the rotating unit 77 (drive motor 71) is operated to rotate the winding roller 50 and the support 83 around the normal to the outer peripheral surface of the forming drum 11 in the same manner as described above, so that the winding roller 50 is tilted. The angle G is inclined in the opposite direction until the same angle as described above, and the drive unit 55 is operated to move (return) the winding roller 50 toward the other end in the width direction of the winding region. As a result, the boundary between the circumferential winding and the spiral winding of the belt-like member 12 is continued with an arc having a relatively small radius of curvature. Thereafter, the belt-like member 12 is spirally wound around the forming drum 11 as described above by further moving (returning) the winding roller 50 toward the other end in the width direction of the winding region. At this time, the direction of inclination of the belt-like member 12 with respect to the circumferential direction of the forming drum 11 is opposite to that described above. In this way, the belt-like member 12 is spirally wound from one end in the width direction of the winding region toward the other end in the width direction.

Then, when the belt-like member 12 is wound to the other end in the width direction of the winding region, the belt-like member 12 is rotated by rotating the winding roller 50 around the normal to the outer peripheral surface of the molding drum 11 as described above. Wind around a predetermined distance in 11 circumferential directions. Thereafter, the winding roller 50 is rotated in the opposite direction (same direction as the first) around the normal line, and is moved toward the one end in the width direction of the winding region (forward movement), and the belt-like member 12 is moved around the forming drum 11. Then, winding is performed along the already wound belt-like member 12 while forming a slight gap between the two belt-like members 12. In this way, while the movable table 41 and the winding roller 50 are reciprocated in the axial direction of the forming drum 11 along the outer peripheral surface of the forming drum 11 by the drive unit 55, the rotation axis A of the winding roller 50 is set to a single plane B. When the belt member 12 is repeatedly inclined in the opposite direction, the belt-like member 12 is wound in a zigzag manner in a plurality of circumferential directions while being folded at both ends in the width direction of the winding region. Attached. At this time, the belt-like member 12 is bent while exhibiting a wave shape of approximately two cycles per circumference of the forming drum 11. Then, the winding as described above is repeated a predetermined number of times, and two plies in which the belt-like members 12 are inclined in the opposite directions at the top and bottom are formed at a time. Such winding may be repeated to form two or more times of plies.

In this way, the winding of the belt-like member 12 around the forming drum 11 is completed as shown in FIGS. 9 and 10, and when the winding roller 50 reaches the center in the width direction of the winding region, the winding roller 50 The reciprocation is stopped and the rotation of the forming drum 11 is stopped. Next, the first moving portion 22 (drive motor 20) of the drive portion 55 is operated to integrally guide the front and rear plates 17, the left and right plates 29, the movable base 41, the winding roller 50, the support 83, and the deformable arm 86. The movable table 41, the winding roller 50, the support body 83 and the like are moved away from the forming drum 11 by moving rearward along the rail 16. At this time, the rotation axis A of the winding roller 50 may remain inclined at the same angle as when the belt-shaped member 12 is wound around the forming drum 11 with respect to the single plane B, or the winding roller 50 May be rotated around the normal line (center axis) so that the rotation axis A is positioned on the single plane B. Then, when the winding roller 50 or the like is separated from the forming drum 11 to a position where no interference occurs between the deforming arm 86 and the forming drum 11 when the deforming arm 86 described later turns, the winding roller 50 or the like moves backward. Stop moving.

At this time, the belt-like member 12 is bridged substantially horizontally between the forming drum 11 and the winding roller 50 while extending in a straight line. As indicated by the line, the contact portion 86 a of the deformable arm 86 waiting at the upper limit is positioned on the center surface F of the winding roller 50. As a result, the movement trajectory (turning trajectory) of the contact portion 86a of the deformable arm 86 intersects the belt-like member 12. Next, the fluid cylinder 88 is operated to retract the piston rod 89, and the contact portion 86a (outer arm 90) of the deformation arm 86 is moved in the direction of the rotation axis of the winding roller 50. As a result, the contact portion 86a is detached laterally from the center surface F of the winding roller 50, and thereby the movement locus (swivel locus) of the contact portion 86a of the deformable arm 86 is offset laterally from the belt-like member 12.

Next, the drive motor 85 is actuated to cause the deformable arm 86 to pivot about the pivot axis from the upper limit to the lower limit indicated by the solid line in FIG. 6. At this time, the contact portion 86a of the deformable arm 86 is As shown by an imaginary line in FIG. 11, it reaches the lower side of the band-shaped member 12 without interfering with the band-shaped member 12 being bridged. Next, by operating the fluid cylinder 88 to project the piston rod 89, the contact portion 86a (outer arm 90) is moved in the direction of the rotation axis of the winding roller 50, and the contact portion 86a is bridged. The lower side of the member 12 is returned to the central surface F of the winding roller 50. The state at this time is shown in FIG. If the fluid cylinder 88 for moving the contact portion 86a of the deformation arm 86 in the direction of the rotation axis of the winding roller 50 is provided in this way, the belt-like member 12 is bridged between the forming drum 11 and the winding roller 50. However, the contact portion 86a of the deformable arm 86 can be moved without receiving any interference.

Next, by operating the drive motor 85 to turn the deformable arm 86 upward, the contact portion 86a is moved upward on the central surface F of the winding roller 50, so that the contact portion 86a is moved upward. The belt-like member 12 is contacted from below while moving. Here, since the contact portion 86a continues to move upward even after such contact, the belt-like member 12 being bridged is pushed up partway by the contact portion 86a of the deformable arm 86, and the belt-like member 12 It is deformed so as to protrude in a direction perpendicular to the front and back surfaces, here upward (convex mountain). The state at this time is shown in FIG. Further, the belt-like member 12 that has been wound around the outer peripheral surface of the winding roller 50 almost half a circumference due to the separation from the forming drum 11 such as the winding roller 50 described above is peeled off from the outer peripheral surface of the winding roller 50. / 4 The amount of wrapping may be reduced to about one turn. Even in such a case, if the belt-like member 12 between the forming drum 11 and the winding roller 50 is deformed so as to protrude as described above, the winding of the belt-like member 12 around the outer peripheral surface of the winding roller 50 is performed. The stickiness can be increased to about 3/4 laps. Thereby, the belt-like member 12 can be surely present on the winding roller 50 at a portion in contact with the forming drum 11 when the winding roller 50 is pressed against the forming drum 11 in the subsequent process.

When the belt-shaped member 12 is deformed in this way, the winding roller 50 and the deformable arm 86 are supported by the support body 83 that is the same member that can rotate around the central axis, and the contact portion 86a of the deformable arm 86 is supported by the belt-shaped member 12. The belt-like member 12 is deformed so as to protrude in a direction perpendicular to the front and back surfaces of the winding roller 50 by moving on the center surface F of the winding roller 50 while being in contact with the roller. Even if the belt-like member 12 is deformed as described above, it is suppressed that the belt-like member 12 is axially displaced from the center surface F of the winding roller 50. As a result, the starting end of the band-shaped member 12 can be pressure-bonded to the forming drum 11 simply by bringing the winding roller 50 close to the forming drum 11 after the band-shaped member 12 is cut.

Further, when the belt-like member 12 is deformed as described above, the belt-like member 12 between the deformable arm 86 and the winding roller 50 is stretched between the protrusion 91 and the protrusion 92 of the outer arm 90 in the air. Next, by operating the cylinder 95 and causing the piston rod 96 to protrude, the bracket 97 is moved toward the contact portion 86a of the deformable arm 86 that has been swung to the upper limit as shown in FIG. When the bracket 97 moves to the vicinity of the contact portion 86a, the belt-like member 12 stretched in the air enters between the

projections

91 and 92 between the cutting blades 98a of the air cutter 98. Next, when the fluid cylinder 101 is operated to cause the piston rod 102 to protrude, the applying roller 104 moves obliquely downward to approach the forming drum 11 while grazing just above the contact portion 86a of the deforming arm 86, and the forming drum 11 The belt-like member 12 bridged between the contact portion 86a is pushed obliquely downward in the vicinity of the contact portion 86a (see FIGS. 6 and 14). As a result, the belt-like member 12 positioned between the contact portion 86a and the forming drum 11 is displaced in a direction (thickness direction) perpendicular to the front and back surfaces thereof, and is deformed so as to protrude downward here. The belt-like member 12 located at the cutting position is given a longitudinal tension while preventing displacement.

Next, when the air cutter 98 is operated, the cutting blade 98a of the air cutter 98 swings like a ridge, and the deformed belt-like member 12 is moved between the contact portion 86a and the winding roller 50 (the projection 91 and the projection 91). Cut in the width direction at the cutting position (between 92). Thus, between the step of deforming the belt-like member 12 to project and the step of cutting the belt-like member 12, the belt-like member 12 positioned between the contact portion 86a and the forming drum 11 is oriented in a direction perpendicular to the front and back surfaces. If the step of applying tension is applied to the strip-shaped member 12 at the cutting position located between the contact portion 86a and the winding roller 50, the strip-shaped member 12 can be cut easily and reliably. . When the belt-like member 12 is cut between the forming drum 11 and the winding roller 50 as described above, the end portion of the belt-like member 12 is on the forming drum 11 side, and the belt-like member is on the winding roller 50 side. Twelve start ends are formed respectively. Here, since there is no restraining end portion of the belt-like member 12 located on the forming drum 11 side, the free-end state is present, but the start end portion of the belt-like member 12 located on the winding roller 50 side is deformed. It is regulated to some extent by the frictional resistance with the

projections

91 and 92 of the arm 86. As a result, even if the winding roller 50 moves so as to approach the forming drum 11 in a subsequent process, the starting end portion does not peel off from the deformation arm 86 and the winding roller 50 and hang down. At this time, since the one-way clutch 64 restricts the strip member 12 from traveling in the direction opposite to the supply direction, even if an external force is applied to the strip member 12 in the direction opposite to the supply direction (backward). The strip member 12 is prevented from traveling (retracting) in the opposite direction.

Next, the

piston rods

96 and 102 of the

cylinders

95 and 101 are retracted to return the air cutter 98 and the applying roller 104 to the initial positions. At this time, after the forming drum 11 is rotated about half a half and the end portion of the belt-like member 12 is moved to the opposite side of the winding roller 50, the belt-like member 12 is manually processed by a processing unit (not shown) or an operator. Is wound around the forming drum 11 along the already wound belt-like member 12, and the end of the belt-like member 12 is parallel to the axis of the forming drum 11 at the center in the width direction of the winding region. Disconnect. In this way, when the band-shaped member 12 is wound around the molding drum 11 a predetermined number of times and a ply as a cylindrical member is molded, after the molding drum 11 is reduced in diameter, it is molded by a transport unit (not shown). The ply is removed from the forming drum 11 and carried out to the next process. Here, the ply molded as described above can be used, for example, as a belt layer, a belt reinforcing layer, or the like for aircraft, passenger car, and truck / bus tires. In addition, after sticking a tread on the outer side of the molded ply to form a belt tread band, the belt tread band may be removed from the wound body. Further, when the wound body is a tire intermediate as described above, a belt layer or the like may be directly formed on the outer peripheral surface of the tire intermediate in the same manner as described above. The belt layer etc. is not removed from the body.

Further, when the ply as described above is continuously manufactured, the driving unit 55 is operated to bring the movable base 41, the support 83, and the winding roller 50 close to the forming drum 11, and the axial direction of the forming drum 11 The winding roller 50 is moved to immediately after one end in the width direction of the winding region, and the winding roller 50 is rotated by the rotating unit 77 so that the rotation axis A of the winding roller 50 is single. It is located on the plane B (horizontal plane). Even if vibration acts on the support 83 during such movement, the deviation of the start end of the belt-like member 12 is restricted by the frictional resistance with the

protrusions

91 and 92, so that the deformation arm 86 and the winding roller 50 There is no peeling. Next, the winding roller 50 is moved toward the forming drum 11 and pressed against the forming drum 11 (one end in the width direction of the winding region), and the start end portion of the belt-like member 12 wound around the outer peripheral surface of the winding roller 50 Is wound onto the outer peripheral surface of the forming drum 11 by the winding roller 50. At this time, since the pressure-bonded portion of the band-shaped member 12 with respect to the forming drum 11 is located at a predetermined distance from the start end of the band-shaped member 12, the band-shaped member 12 on the start end side from the pressure-bonded portion is not pressure-bonded to the forming drum 11, It is in a free state without being restrained. Then, after pressing the belt-shaped member 12 against the molding drum 11, the axial movement of the winding roller 50 is restricted, and the molding drum 11 is rotated around the axis by a predetermined angle while feeding the belt-shaped member 12 to the molding drum 11. The belt is rotated, and the starting end portion of the belt-like member 12 is wound around the outer circumferential surface of the forming drum 11 in the circumferential direction by a specified length slightly longer than the circumferential portion 12a.

When the starting end of the belt-like member 12 is wound around the forming drum 11 in this way, the rotation of the forming drum 11 is temporarily stopped, and the drive motor 85 is operated to turn the deformation arm 86 downward, The contact portion 86a of the deformation arm 86 is moved closer to the outer peripheral surface of the forming drum 11. As a result, the contact portion 86a comes into contact with the starting end portion of the belt-like member 12 wound around the outer peripheral surface of the molding drum 11, and presses the belt-like member 12 at the portion against the molding drum 11. After the step of crimping the starting end of the band-shaped member 12 to the forming drum 11 by the winding roller 50 as described above, the forming drum 11 is rotated while supplying the band-shaped member 12, and the starting end of the band-shaped member 12 is moved to the forming drum 11. And a step of moving the contact portion 86a of the deformation arm 86 and pressing the start end portion of the belt-like member 12 wound around the forming drum 11 against the forming drum 11 by the contact portion 86a of the deformation arm 86. By doing so, the crimping of the starting end portion of the band-shaped member 12 to the forming drum 11 becomes more reliable, and the starting end portion is peeled off from the forming drum 11 when the band-shaped member 12 is continuously wound around the forming drum 11. The situation can be effectively prevented. Thereafter, the deformable arm 86 is turned upward to return the contact portion 86a to the upper limit.

As described above, when the belt-like member 12 is wound around the outer peripheral surface (one end in the width direction of the winding region) of the forming drum 11 by a predetermined length in the circumferential direction, the forming drum 11 is rotated around the axis, while the winding roller 50, the belt-like member 12 is wound about 2 to 3 times in a zigzag manner around the winding region of the forming drum 11 as described above. Then, when the starting end of the belt-like member 12 reaches the opposite side of the winding roller 50, the rotation of the forming drum 11 and the movement of the winding roller 50 are stopped. Next, a belt-like member that is wound around the molding drum 11 in a circumferential direction by peeling off a part of the starting end of the belt-like member 12 from the molding drum 11 by a processing unit (not shown) or an operator's manual work. The length of 12 is corrected to the length of the circumferential portion 12a. Thereafter, the starting end of the strip-shaped member 12 that has been peeled off is wound around the forming drum 11 along the already-rolled strip-shaped member 12, and the starting end of the strip-shaped member 12 is centered in the width direction of the winding region. And cutting in parallel to the axis of the forming drum 11. Thus, if both the starting end and the terminal end of the belt-like member 12 are cut parallel to the axis of the forming drum 11, the quality of the manufactured cylindrical body can be easily improved. Further, as described above, since the start end and the end end of the belt-like member 12 are both located at the center in the width direction of the winding region, the rotational balance of the cylindrical body is good. Next, in the same manner as described above, the belt-like member 12 is wound around the outer periphery of the forming drum 11 in a zigzag manner one after another.

In the present invention, when the winding direction of the belt-like member 12 is changed from a state inclined with respect to the circumferential direction to a state parallel to the circumferential direction, the rotation of the forming drum 11 is temporarily stopped while being parallel to the circumferential direction. When the winding direction of the belt-like member 12 is changed from the normal state to the inclined state with respect to the circumferential direction, the forming drum 11 may be rotated from the stopped state.

This invention can be applied to the industrial field in which a belt-like member is wound around the outer peripheral surface of a body to be wound in a zigzag manner.
