BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is capable of rotating around a rotation axis, and a narrow band-like strip is formed on the outer surface of a rotating body in which the radius from the rotation axis changes to the outer surface depending on the axial position. The present invention relates to a belt-shaped member winding device that winds a member in a spiral shape.

2. Description of the Related Art Conventionally, as a winding device for a linear object,
For example, those described in JP-A-62-48535 are known. This is provided on the movable base, and a screw shaft extending parallel to the rotation axis of the toroidal tire constituent member, a movable base screwed onto the screw shaft and movable along the screw shaft by rotation of the screw shaft. A tilting block that has a rotating block that rotates around a vertical axis by a torque actuator and a rail that is slidably fitted to the rotating block, and that tilts on the floor by receiving the rotating force from the rotating block. A plate and a rear surface having the same shape as the projected shape of the crown portion of the tire constituent member,
The rear surface guides a linear object supported by a contour block which is in contact with the front surface of the tilt plate without slipping, a screw shaft supported by the tilt plate and extending along the tilt plate, and a moving frame screwed to the screw shaft. And a sensor for measuring the distance between the moving frame and the contour block.

When the linear member is helically wound around the tire constituent member by this means, the tire constituent member is rotated around the rotation axis and the screw shaft is rotated to guide the linear member. Is moved along the axis of rotation of the tire component. Thereby, the linear object is spirally wound around the outer surface of the tire constituent member. At this time, since the radius of the tire component changes according to the axial position, this movement causes the distance between the moving frame and the contour block to become a predetermined value or more. As a result, a signal is sent from the sensor to the screw shaft, the screw shaft rotates, and the movable table moves along the screw shaft. At this time, since the turning force is applied from the torque actuator to the tilting plate through the turning block, the tilting plate contacts the rear surface of the contour block, that is, until it becomes parallel to the tangent to the outer surface of the tire constituent member. Tilt. As a result, the supply roller moves following the outer surface of the tire constituent member and feeds the linear object substantially along the normal line of the tire constituent member.

However, such a conventional winding device for a belt-shaped member has a problem in that the structure is complicated and the manufacturing cost is high.

An object of the present invention is to provide a belt-shaped member winding device which has a simple structure and can be manufactured at low cost.

[0006]

Such an object is to provide an outer surface of a rotating body which is rotatable about an axis of rotation and whose radius from the axis of rotation to the outer surface changes depending on the axial position. A band-shaped member winding device for spirally winding a band-shaped member having a width, comprising: a support base, a moving means for moving the support base parallel to a rotation axis of a rotating body, and the support base orthogonal to a rotation axis of the rotating body. A contacting / separating means for moving the support base toward and away from the rotating body by moving in parallel to the straight line, and a straight line substantially parallel to the tangent line to the outer surface of the rotating body at the winding position of the belt-shaped member around the support body A guide for guiding the belt-shaped member supplied to the rotating body, and a rotating means for rotating the guide about a straight line substantially parallel to the tangent line, a moving means, a contact Control the separation means By changing the positions of the support base and the guide while following the outer surface shape of the rotating body and controlling the rotating means, the normal line to the rotating body at the winding position and the strip-shaped member at the winding position are controlled. It is possible to achieve this by including a control unit configured to make the front and back surfaces orthogonal to each other.

[0007]

When the belt-shaped member is spirally wound around the outer surface of the rotating body, the rotating body is rotated and the belt-shaped member guided by the guide is supplied to the rotating body. At the same time, the moving means is operated. The support and guide are moved parallel to the rotation axis of the rotating body. As a result, the belt-shaped member is spirally wound around the outer surface of the rotating body. Here, since the radius of the rotating body changes according to the axial position, simply moving the support base and the guide parallel to the rotation axis of the rotating body causes the guide to move away from the outer surface of the rotating body. There is a risk of passing or approaching too much. Therefore, in the present invention,
At the same time, the contacting / separating means is operated to move the support base and the guide in parallel with a straight line orthogonal to the rotation axis of the rotating body, thereby separating the support base and the guide from the rotating body. The movement of the support base by the contacting / separating means is performed based on the information about the outer surface shape of the rotating body stored in advance in the control means, whereby the guide moves relative to the outer surface of the rotating body. Is maintained almost constant. Further, even if the radius of the rotating body changes depending on the axial position as described above, if the front and back surfaces of the belt-shaped member supplied through the guide are always parallel to the rotation axis of the rotating body, Only one side end of the member may be crimped to the outer surface of the rotating body, and the other side end may float up from the outer surface of the rotating body. There is also a risk of slippage. Therefore, in the present invention,
By transmitting a signal from the control means to the rotating means based on the information stored as described above to operate the rotating means, the tangential line to the outer surface of the rotating body at the winding position of the belt-shaped member around the rotating body is formed. The guide is rotated around a substantially parallel straight line so that the normal line to the rotating body at the winding position and the front and back surfaces of the strip-shaped member at the winding position are orthogonal to each other. As described above, in the present invention, the moving means for moving the support base in the axial direction of the rotating body, the contacting / separating means for moving the supporting base in parallel to the straight line orthogonal to the rotation axis of the rotating body, and the guide are tangential to the outer surface of the rotating body. The belt-shaped member can be satisfactorily wound around the outer surface of the rotating body only by providing the rotating means for rotating about the substantially parallel straight line, and the structure can be simplified and the manufacturing cost can be reduced.

If the rate of change of the radius of the rotating body, that is, the difference in radius between the positions separated by a unit length in the direction of the rotation axis of the rotating body becomes large, the strip-shaped member wound around the portion and the rotating body become larger. The angle of intersection with the axis of rotation becomes large, which may cause a gap between the wound strip members. Therefore, in the invention described in claim 2,
The moving means, that is, the movement of the support base in the direction of the rotation axis is controlled by the control means, and as the change rate of the radius of the rotating body increases, the moving pitch of the support base per one rotation of the rotating body is decreased to reduce the gap. It prevents the occurrence.

The front and back surfaces of the belt-shaped member 15 at the winding position M are orthogonal to each other.

Next, the operation of the embodiment of the present invention will be described. Now, as shown in FIG. 4, it is assumed that the starting end portion of the belt-shaped member 15 is located at the gripping position H and the gripping means 71 is on standby just above the gripping position H. At this time, since the piston rod 77 of the cylinder 75 is protruding, the cylinder 56 and the support 5
7. The gripping means 71 swings upward around the pin 55 and is located above the strip-shaped member 15. Next, the cylinder 75 is operated to retract the piston rod 77, and the cylinder 56 and the support
57, the grip means 71 is swung downward around the pin 55, and the grip block 65 of the grip means 71 is pressed against the starting end portion of the belt-shaped member 15 from above. Next, the piston rod 92 of the cylinder 91 is projected to swing the swinging body 89 upward. As a result, the starting end portion of the belt-shaped member 15 located at the gripping position H is bent upward by the rocking member 89 and pressed against the arcuate lower end of the gripping block 65. Next, pull in the piston rod 70 of the cylinder 69, and
A band-shaped member in which 67 swings so as to approach the grip block 65 around the pin 68 and is pressed against the grip block 65.
The starting end portion of 15 is gripped from the front and back sides by the grip claw 67 and the grip block 65. The state at this time is shown in FIG.

Next, the piston rod 92 of the cylinder 91 retracts, and the oscillating body 89 oscillates downward to return to the initial position retracted from the upper surface of the guide plate 43. Next, the piston rod 77 of the cylinder 75 projects,
57, the gripping means 71 swings upward about the pin 55, and the starting end portion of the belt-shaped member 15 is slightly lifted up by the gripping means 71. At this time, the belt-shaped member 15 immediately after the gripping means 71
Are guided by guide rollers 84. Next, the piston rod 96 of the cylinder 95 retracts, the pressing plate 99 rises, and the band-shaped member 15 is released from the pressing and fixing by the pressing plate 99. At this time, the cylinder 100 operates, the piston rod 101 projects, and the slide block 94 and the cylinder 95
Moves forward. Next, the cylinder 50 piston rod
51 protrudes, and the movable base 48, the cylinder 56, the support 57, and the gripping means 71 that grips the starting end of the belt-shaped member 15 move together toward the front to approach the rotating body 11. And
This approaching movement is stopped when the grip body 71 reaches directly above the top of the rotating body 11. As a result, the starting end of the belt-shaped member 15 is supplied from the gripping position H to the top of the rotating body 11. At this time, the starting end of the belt-shaped member 15 is gripped from the front and back sides by the gripping means 71, but since such a gripping force is a mechanical force, it can be increased as necessary, and as a result, Even if a large external force or the like acts on the belt-shaped member 15 during supply, the belt-shaped member 15 does not come off or deviate from the gripping means 71, and the starting end portion of the belt-shaped member 15 can be reliably and accurately rotated. Can be supplied to 11. The state at this time is shown in FIG.

Next, the cylinder 75 is operated to retract the piston rod 77, and the cylinder 56, the support body 57, and the gripping means 71 are swung downward around the pin 55. As a result, the grip block 65 is pressed against the rotating body 11, and the strip-shaped member 15 that is gripped by the grip block 65 and the grip claw 67.
The starting end of the is pressed onto the top of the rotating body 11. At this time,
The piston rod 79 of the cylinder 78 projects, and the guide roller 84 that guides the belt-shaped member 15 moves toward the outer surface of the rotating body 11. Next, the piston rod 70 of the cylinder 69 projects and the grip claw 67 swings so as to separate from the grip block 65. As a result, the starting end portion of the belt-shaped member 15 is released from the grip of the grip block 65 and the grip claw 67. Next, the piston rod 61 of the cylinder 56 is projected and the moving block 59
Move forward. At this time, the grip block
Since the lower end of 65 is pressed against the outer surface of the rotating body 11 via the strip-shaped member 15, the grip block 65 cannot slide between the strip-shaped member 15 and the pin 66 located at the upper end is the center. Swing backwards. Here, since the lower end portion of the grip block 65 has an arc shape centered on the pin 66, the starting end portion of the band-shaped member 15 is pressed and crimped while being stroked onto the rotating body 11 by the lower end portion of the grip block 65. .. As a result, the strip-shaped member 15 at the portion which is not pressed against the rotating body 11 by being held between the holding claw 67 is reliably and highly accurately crimped to the rotating body 11 by the holding block 65 having a simple structure. It At this time, the pressure roller 97 approaches the rotating body 11 and contacts the outer surface of the rotating body 11. The state at this time is shown in FIG.

Next, the piston rod 77 of the cylinder 75 projects, the cylinder 56, the support 57, and the grip means 71 swing upward about the pin 55, and the grip block 65 retreats upward. Next, the piston rod 61 of the cylinder 56 is retracted, and the moving block 59 and the grip means 71 are moved rearward by the same distance as the forward movement distance. Next, while rotating the rotating body 11, the strip-shaped member 15 guided by the guide 85.
Is supplied to the rotating body 11. At the same time, the control means 98 actuates the motor 31 of the moving means 32 to rotate the screw shaft 27, thereby moving the support base 30 and the guide 85 outward in the axial direction parallel to the rotation axis Q of the rotating body 11. As a result, the belt-shaped member 15 is spirally wound around the outer surface of the rotating body 11 and pressed by the pressing roller 97. Where the rotating body
The radius R of 11 changes according to the axial position. Here, since the radius R becomes smaller toward the outer side in the axial direction, the support base 30 and the guide 85 are simply set to the rotation axis Q of the rotating body 11. If you move the guide 85 in parallel, the guide 85
Gradually separate from the outer surface of the. Therefore, in this embodiment, the control means 98 actuates the motor 23 of the contacting / separating means 33 to rotate the screw shaft 20, so that the support base 30 and the guide 85 are parallel to a straight line orthogonal to the rotation axis Q of the rotating body 11. In this case, move it downward along the vertical line,
To approach the rotating body 11. And such contact and separation means
The movement of the support base 30 and the guide 85 by the 33 is controlled by the control means 98 in advance.
Is controlled on the basis of the information on the outer surface shape of the rotating body 11 stored in the table and the current axial position information of the support base 30 and the guide 85 input from the encoder 34. The relative position of 11 with respect to the outer surface is kept approximately constant. In addition, as described above, the rotating body 11
Although the radius R of the strip member 15 varies depending on the axial position, if the front and back surfaces of the strip member 15 supplied through the guide 85 are always parallel to the rotation axis Q of the rotating body 11,
Only one side end (axial inner end) is crimped to the outer surface of the rotating body 11, and the other side end (axial outer end) may rise above the outer surface of the rotating body 11. At the same time, the wound belt-shaped member 15 may be displaced outward in the axial direction of the rotating body 11. Therefore, in this embodiment, the information and encoder stored as described above is used.
Based on the position information from 34, the control means 98 to the rotation means 86.
To send a signal to the motor 41 of the
85 is rotated about a straight line substantially parallel to the tangent to the outer surface of the rotating body 11 at the winding position M. As a result, the front and back surfaces of the strip-shaped member 15 at the winding position M and the normal line N to the rotating body 11 at the winding position M are orthogonal to each other (see FIG. 3), and the situation as described above is prevented. As described above, in this embodiment, the moving means 32 for moving the support base 30 in the axial direction of the rotating body 11, the contacting / separating means 33 for moving the supporting body 30 in parallel to the straight line orthogonal to the rotation axis Q of the rotating body 11, and the guide 85 are provided. By simply providing the rotating means 86 for rotating about a straight line substantially parallel to the tangent to the outer surface of the rotating body 11, the belt-shaped member 15 can be well wound around the outer surface of the rotating body 11, and the structure is simple. It can be manufactured at low cost. Then, as shown in FIG. 3, when the belt-shaped member 15 is wound around the axially outer end portion of the rotating body 11,
Since the rate of change of the radius R of the rotating body 11, that is, the difference of the radius R between the positions separated by a unit length in the rotating axis direction of the rotating body 11, becomes large, the rotating axis of the belt-shaped member 15 wound around the portion increases. The inclination angle with respect to Q becomes large, and as a result, the rotor
If the moving distance (pitch) in the axial direction of the support base 30 and the guide 85 per one rotation of 11 is constant, a gap is generated between the wound belt-shaped members 15. Therefore, in this embodiment, the control means 98 controls the moving means 32, that is, the support base 30,
The movement of the guide 85 in the direction of the rotation axis is controlled so that the movement pitch P of the support base 30 per one rotation of the rotating body 11 becomes smaller as the rate of change of the radius R of the rotating body 11 becomes larger, and the above-mentioned gap is generated. Is being prevented. The state at this time is shown in FIG.

When the strip-shaped member 15 is spirally wound around the rotating body 11 a predetermined number of times in this manner, the rotating body 11 is rotated.
And the operation of the motors 31, 23, 41 is stopped. Next, the cylinder 95 operates and the piston rod
96 protrudes, and the holding plate 99 slides the strip-shaped member 15
Push it to 94 and fix it. Next, the cutter 93 descends to cut the belt-shaped member 15 in the width direction in cooperation with the guide plate 43 at the cutting position. At this time, the belt-shaped member 15 immediately before the cutting position is guided or fixed by the guide roller 84, while the belt-shaped member 15 immediately after the cutting position is guided or fixed by the holding plate 99, so that the belt-shaped member 15 moves or deforms at the time of cutting. There is nothing to do. The state at this time is shown in FIG. Next, the cutter 93 moves up to the initial position.
Next, the rotating body 11 is rotated by a predetermined angle, and the terminal end portion of the cut strip-shaped member 15 is pressure-bonded to the rotating body 11 by the pressure roller 97. Next, the cylinder 78 is operated to operate the piston rod 79.
Retract the guide roller 84 and activate the cylinder 50 to retract the piston rod 51,
Return 48 to the initial position. At this time, the cylinder 100 is operated to retract the piston rod 101, and the slide block 94, the pressing plate 99, and the belt-shaped member 15 are integrally moved rearward, and the starting end portion of the belt-shaped member 15 is pulled back to the gripping position H. Next, the pressure roller 97 rises and separates from the rotating body 11. After that, a tread rubber is attached around the rotating body 11 to form a raw tire, and the raw tire is carried out from the molding drum and a new tire intermediate is carried into the molding drum. The above is one cycle of the operation of this embodiment, and thereafter, this cycle is repeated.
