Description

Technical Field

[0001] This invention relates to an apparatus and method for manufacturing cylindrical tire components, and more specifically, to an apparatus and method for manufacturing high-quality cylindrical tire components by smoothly and rapidly feeding strip-shaped tire material supplied in a horizontal position by a plurality of parallel conveyors to a forming drum and positioning it in the drum width direction with high precision. Background Technology

[0002] Tires are manufactured by vulcanizing green tires. Green tires are formed by layering multiple types of tire materials. For example, a green tire is formed by integrating the inner liner, carcass material, belt material, tread rubber, and a pair of bead components onto a forming drum.

[0003] The following apparatus is proposed: when supplying multiple types of strip tire materials to a forming drum, conveyors that supply each tire material in a flat position are arranged in an overlapping area in the vertical direction, and the forming drum is moved vertically according to the front end position of each conveyor (see Patent Document 1). Figure 2 (etc.). By configuring the conveyors in this way, the device is made compact. The forming drum 2 is positioned in front of the parallel conveyors 10 by moving along the track 8 in the drum width direction. The tire material supplied by each conveyor 10 is wound around the forming drum to produce a cylindrical tire component.

[0004] When there is a deviation in the drum width direction position of a single sheet of tire material supplied to the forming drum, the tire material is wound around the forming drum in a meandering manner, thus becoming a major cause of reduced quality in the cylindrical tire component. Furthermore, when multiple sheets of tire material are sequentially wound and stacked on the forming drum, if there is a deviation in the drum width direction position of each supplied tire material, the individual tire materials are stacked out of proportion in the width direction, thus becoming a major cause of reduced quality in the cylindrical tire component (laminated body). By moving the forming drum relative to the supplied tire material in the width direction, the deviation in the drum width direction position of the tire material can be corrected. However, in the device proposed in Patent Document 1, not only does the forming drum 2 move along the track 8, but the assembly unit 1, including the vertical support body 15 supporting the forming drum 2, also moves integrally along the track 8. Therefore, in order to correct the deviation in the drum width direction position of the tire material, it is necessary to move the assembly unit 1, which is larger and heavier than the forming drum 2, along the drum width direction, making it difficult to move the forming drum 2 quickly along the drum width direction. Consequently, it is not conducive to the smooth and rapid supply of tire material to the forming drum and the precise positioning of the drum width direction for winding, so there is room for improvement.

[0008] The problem that the invention aims to solve

[0009] The object of the present invention is to provide an apparatus and method for manufacturing high-quality tubular tire components by smoothly and rapidly feeding strip-shaped tire material supplied by multiple parallel conveyors in a flat state to a forming drum and positioning it in the drum width direction with high precision.

[0010] Methods for solving problems

[0011] To achieve the above objectives, the manufacturing apparatus for a cylindrical tire component of the present invention includes: a conveyor that supplies strip-shaped tire material in a flat state; and a forming drum that winds the tire material supplied by the conveyor to form the tire material into a cylindrical shape, wherein a plurality of conveyors are arranged side by side in the drum width direction, the manufacturing apparatus includes: a sliding movement mechanism that causes the forming drum to slide in the drum width direction; and a vertical movement mechanism that causes the forming drum to move vertically, characterized in that an upper structural portion including the forming drum is disposed on a base portion, the base portion and the upper structural portion are connected by the vertical movement mechanism, the manufacturing apparatus is configured such that a drum unit including the base portion, the upper structural portion and the vertical movement mechanism is moved integrally in the drum width direction by means of the sliding movement mechanism, the upper structural portion having a drum moving mechanism for moving the forming drum in the drum width direction, the drum moving mechanism being a separate mechanism from the sliding movement mechanism.

[0012] The present invention discloses a method for manufacturing a cylindrical tire component, wherein multiple conveyors are arranged side-by-side relative to a forming drum in the drum width direction. When strip-shaped tire material supplied by each of the conveyors in a horizontal position is wound around the forming drum to form a cylindrical shape, a sliding moving mechanism for moving the forming drum in the drum width direction and a vertical moving mechanism for moving the forming drum in the vertical direction are used to move the forming drum to a winding position near the front end of the conveyor that supplies the tire material to the forming drum. Then, the tire material supplied by the conveyor is wound around the forming drum at the winding position. The method is characterized in that an upper structural part including the forming drum is disposed on a base portion, and the vertical moving mechanism is connected to the upper structural part. The base portion and the upper structural portion are connected. The upper structural portion has a drum moving mechanism, which is separate from the sliding moving mechanism, for moving the forming drum body in the drum width direction. The sliding moving mechanism moves the drum unit, which includes the base portion, the upper structural portion, and the up-down moving mechanism, together in the drum width direction. The up-down moving mechanism moves the upper structural portion in the up-down direction, thereby moving the forming drum body to the winding position. At the winding position, the drum moving mechanism moves the forming drum body in the drum width direction, thereby correcting the deviation of the position of the tire material wound around the forming drum body in the drum width direction while winding the tire material around the forming drum body.

[0013] Invention Effects

[0014] According to the present invention, the drum unit is moved integrally in the drum width direction by the sliding moving mechanism, and the upper structural part is moved in the vertical direction by the vertical moving mechanism, thereby enabling the forming drum to be moved to the appropriate winding position where the tire material can be smoothly transferred from the conveyor to the forming drum. At the winding position, the forming drum is moved in the drum width direction by the drum moving mechanism, thereby correcting deviations in the drum width direction position of the tire material when winding it onto the forming drum. Furthermore, the drum moving mechanism moves the forming drum in the drum width direction, not the drum unit, thus facilitating the rapid movement of the forming drum to the desired drum width direction position. As a result, the tire material can be smoothly and rapidly supplied to the forming drum from the parallel conveyors, and the drum width direction positioning can be performed with high precision. Consequently, at the forming drum, the tire material can be formed into a cylindrical shape with suppressed deviations in the drum width direction, thus facilitating the efficient manufacture of high-quality cylindrical tire components.

[0024] Hereinafter, the manufacturing apparatus and method for the cylindrical tire component of the present invention will be described based on the embodiments shown in the accompanying drawings.

[0025] use Figures 1-3 In the embodiment of the illustrated cylindrical tire component manufacturing apparatus 1, strips of tire materials M1 and M2, supplied in a horizontal position by conveyors 10a and 10b, are wound around a forming drum 6 to produce a cylindrical tire component M. For example, inner liner and carcass materials are used as tire materials M1 and M2, and are sequentially supplied to the forming drum 6 to produce an inner liner layer and a carcass layer as the cylindrical tire component M, which are then stacked. A green tire G is formed using the inner liner layer and the carcass layer. A tire T is manufactured by vulcanizing the formed green tire G.

[0026] The manufacturing apparatus 1 includes conveyors 10a and 10b that supply tire materials M1 and M2 in a flat position, a drum unit 2 containing a forming drum 6, a sliding movement mechanism 8 that slides the drum unit 2 along the width direction of the drum, and a vertical movement mechanism 9 that moves the forming drum 6 vertically. In this embodiment, the manufacturing apparatus 1 also includes a sensor 11 and a control unit 12. The X, Y, and Z arrows in the figure represent the width direction, front-back direction, and height direction of the manufacturing apparatus 1 (forming drum 6), respectively, and are mutually orthogonal. In the figures, the direction from the conveyors 10a and 10b toward the forming drum 6 in the front-back direction (Y direction) is forward.

[0027] Conveyors 10a and 10b are belt conveyors or similar conveying units. Multiple conveyors 10a and 10b are arranged side-by-side in the drum width direction. Each conveyor 10a and 10b is substantially fixed to a certain position on the foundation and does not move. In this embodiment, the front-to-back position of the front ends of each conveyor 10a and 10b is set to substantially the same position, while the vertical position is set to slightly different positions. Alternatively, the front-to-back position of the front ends of each conveyor 10a and 10b can be set differently, or the vertical position can be set to substantially the same position.

[0028] The forming drum 6 winds tire materials M1 and M2 supplied by conveyors 10a and 10b to form the tire materials M1 and M2 into a cylindrical shape. The drum axis C of the forming drum 6 extends along the X direction. The forming drum 6 rotates around the drum axis C via a rotation drive unit 6a.

[0029] The drum unit 2 is an integral structure comprising a base portion 3, an upper structural portion 4, a sliding mechanism 8, and a vertical moving mechanism 9. The drum unit 2 is divided into a base portion 3 and an upper structural portion 4, with the upper structural portion 4 positioned above the base portion 3. The base portion 3 and the upper structural portion 4 are connected by the vertical moving mechanism 9.

[0030] The base portion 3 is mounted on a guide rail 2a that extends along the width direction of the drum on the foundation. A drive motor or the like constituting a sliding movement mechanism 8 is provided on the base portion 3. Various known mechanisms that move the base portion 3 along the guide rail 2a can be used as the sliding movement mechanism 8. When the base portion 3 is moved along the guide rail 2a by means of the sliding movement mechanism 8, the drum unit 2, which includes the shaped drum body 6, moves in the width direction of the drum.

[0031] The upper structural section 4 includes a mounting plate 5a, a sliding plate 5b, a forming drum 6, a rotation drive unit 6a, and a drum moving mechanism 7. The forming drum 6 and the rotation drive unit 6a are disposed on the sliding plate 5b, which is mounted on the mounting plate 5a. The sliding plate 5b engages, for example, with a groove formed on the mounting plate 5a extending in the drum width direction. The drum moving mechanism 7 is disposed on the mounting plate 5a.

[0032] The drum moving mechanism 7 moves the forming drum body 6 along the drum width direction within the upper structural part 4. In this embodiment, when the sliding plate 5b moves relative to the mounting plate 5a in the drum width direction via the drum moving mechanism 7, the forming drum body 6 and the rotation drive part 6a move in the drum width direction. Various known mechanisms, such as fluid cylinders or levers that move forward and backward via servo motors, can be used as the drum moving mechanism 7. The drum moving mechanism 7 is a separate mechanism from the sliding moving mechanism 8.

[0033] The up-and-down movement mechanism 9 moves the upper structural part 4 up and down relative to the base part 3. Various known mechanisms, such as a fluid cylinder or a lever that moves forward and backward via a servo motor, can be used as the up-and-down movement mechanism 9. In this embodiment, the up-and-down movement mechanism 9 is located between the base part 3 and the mounting plate 5a. When the upper structural part 4 moves up and down relative to the base part 3 using the up-and-down movement mechanism 9, the forming drum 6 moves up and down.

[0034] Sensor 11 is disposed above each of the conveyors 10a and 10b. Sensor 11 detects the presence and position of tire materials M1 and M2 mounted on the conveyors 10a and 10b. Various known non-contact detection sensors can be used as sensor 11. Multiple sensors 11 can be arranged at intervals along the width direction (X direction) or along the supply direction (Y direction) of each tire material M1 and M2. The detection data from the sensor 11 is sequentially input to the control unit 12. This detection data includes the width direction position of the tire materials M1 and M2 on the conveyors 10.

[0035] The control unit 12 performs calculations using the input data, stored data, etc., and controls various components of the manufacturing apparatus 1. Various known computers can be used as the control unit 12.

[0036] Next, an example of the steps for manufacturing a cylindrical tire component M using the manufacturing apparatus 1 will be described.

[0037] In this manufacturing apparatus 1, multiple conveyors 10a and 10b arranged side-by-side relative to the forming drum 6 in the drum width direction are used to supply and wind tire materials M1 and M2 in a flat state onto the forming drum 6. When supplying each tire material M1 and M2, the forming drum 6 is moved and positioned near the front end of the conveyors 10a and 10b that supply the tire materials M1 and M2 (winding positions P1 and P2).

[0038] First, such as Figure 4 , Figure 5As illustrated, the forming drum 6 is moved and positioned at a winding position P1 near the front end of the conveyor 10a that supplies tire material M1 to the forming drum 6. Therefore, as... Figure 4 As illustrated, the drum unit 2 is moved integrally in the drum width direction and aligned with the winding position P1 (X-direction position) by the sliding movement mechanism 8. Additionally, as... Figure 5 As illustrated, the upper structural section 4 is moved vertically and aligned with the winding position P1 (Z-direction position) by the vertical moving mechanism 9. The winding position P1 is a suitable position that allows the tire material M1 to be smoothly transferred from the conveyor 10a to the forming drum 6.

[0039] The positions of the front end of conveyor 10a (X-direction, Y-direction, and Z-direction positions) are preset, and the Y-direction position of the forming drum 6 is also preset. Therefore, by conducting prior tests to transfer tire material M1 from conveyor 10a to forming drum 6 in various ways with different X-direction and Z-direction positions, the winding position P1 is predetermined. The winding position P2 is also predetermined for the other conveyor 10b in the same way.

[0040] By pre-determining the winding position P1, when supplying tire material M1 to the forming drum 6, the sliding movement mechanism 8 adjusts the drum width direction position of the forming drum 6, and the up-down movement mechanism 9 adjusts the up-down position of the forming drum 6 to position it at the winding position P1. Specifically, to position the forming drum 6 at the winding position P1, the control unit 12 controls the sliding movement mechanism 8 to adjust the drum width direction position of the forming drum 6 based on the drum width direction position of the front end of the conveyor 10a supplying tire material M1. Furthermore, the control unit 12 controls the up-down movement mechanism 9 to adjust the up-down position of the forming drum 6 based on the up-down position of the front end of the conveyor 10a. Through this control, the forming drum 6 can be automatically positioned at the winding position P1. In order to set the forming drum 6 more quickly at the winding position P1, during the period when the forming drum body 6 (drum unit 2) is moved toward the winding position P1 in the drum width direction by the sliding moving mechanism 8, the forming drum body 6 is moved in the vertical direction by the up-down moving mechanism 9 and aligned with the height position of the winding position P1.

[0041] Next, as Figure 6 As illustrated, at the winding position P1, the forming drum 6 is rotated around the drum axis C to wind the tire material M1 supplied by the conveyor 10a. Since much of the tire material M1 placed on the conveyor 10a tends to meander in the drum width direction, the deviation (meaning) of the position of the tire material M1 wound on the forming drum 6 in the drum width direction is corrected by using the drum moving mechanism 7 to move the forming drum 6 in the drum width direction.

[0042] In this embodiment, the tire material M1, which is placed flat on the conveyor 10a, is detected by the sensor 11, and the width direction position data of the tire material M1 detected by the sensor 11 is sequentially input to the control unit 12. The control unit 12 compares the input width direction position data of the tire material M1 with the stored reference value for the width direction position data of the tire material M1, and controls the drum moving mechanism 7 to move the forming drum 6 in the drum width direction in a way that reduces the difference between the two. The reference value is the data representing the width direction position of the tire material M1 when the tire material M1 is not winding. That is, the tire material M1 is wound around the forming drum 6 while adjusting the drum width direction position of the forming drum 6 in a way that prevents the tire material M1 from winding in a winding state. In other words, the tire material M1 is wound in a way that centers the center position of the tire material M1 in the width direction to the center position of the forming drum 6 in the width direction. As a result, a tire component M in which the tire material M1 is shaped into a cylindrical shape is manufactured at the forming drum 6.

[0043] Next, as Figure 7 , Figure 8 As illustrated, in order to manufacture a cylindrical tire component M using tire material M2 supplied from another conveyor 10b, the forming drum 6 is moved to a winding position P2 near the front end of the other conveyor 10b. The step of setting the forming drum 6 at the winding position P2 is the same as the step of setting it at the winding position P1 described above. That is, as... Figure 7 As illustrated, the drum unit 2 is moved integrally in the drum width direction by the sliding movement mechanism 8. Additionally, as... Figure 8 As illustrated, the upper structural part 4 is moved in the vertical direction by the vertical moving mechanism 9.

[0044] Next, as Figure 9 As illustrated, at the winding position P2, the forming drum 6 is rotated around the drum axis C while the tire material M2 supplied by the conveyor 10b is wound. Much of the tire material M2 placed on the conveyor 10b will meander in the drum width direction. Therefore, by using the same steps as in the case of tire material M1, the forming drum 6 is moved in the drum width direction using the drum moving mechanism 7, thereby correcting the deviation (meandering) in the drum width direction position of the tire material M2 wound on the forming drum 6.

[0045] Since a cylindrical tire component M has already been manufactured and wound on the forming drum 6, tire material M2 is wound onto the outer peripheral surface of the tire component M at the winding position P2. Therefore, at the winding position P2, the cylindrical tire component M formed from tire material M2 is manufactured in a stacked state relative to the tire component M already manufactured on the forming drum 6.

[0046] As described above, in this manufacturing apparatus 1, the sliding moving mechanism 8 and the up-and-down moving mechanism 9 can be used to move the forming drum 6 with high precision to appropriate winding positions P1 and P2, which allow the tire materials M1 and M2 to be smoothly transferred from the respective conveyors 10a and 10b. Consequently, it is not necessary to excessively slow down the transfer speed of the tire materials M1 and M2 to the forming drum 6, thus facilitating rapid and non-deviation-free transfer to the forming drum 6.

[0047] Furthermore, at winding positions P1 and P2, the forming drum 6 is moved in the drum width direction by the drum moving mechanism 7, thereby enabling the tire materials M1 and M2 to be wound onto the forming drum 6 while correcting deviations in their drum width direction positions. The drum moving mechanism 7 does not move the drum unit 2 in the drum width direction, but rather moves the forming drum 6 (in this embodiment, only the forming drum 6, the rotary drive unit 6a, and the sliding plate 5b) which are components of the drum unit 2 in the drum width direction. These forming drums 6 and their associated components are lighter and smaller than the drum unit 2, thus facilitating the rapid movement of the forming drum 6 to the desired drum width direction position.

[0048] That is, the forming drum 6 can be moved quickly and smoothly to one side and the other side of the drum width direction by correcting deviations in the width direction position of the wound tire materials M1 and M2. If the drum unit 2 is heavy, the inertial force will be large, and it will be difficult to move it quickly in the width direction, but this is not the case in this embodiment. Along with this, the drum width direction positioning of the tire materials M1 and M2 can be performed with high precision without slowing down the winding speed (drum rotation speed) of the tire materials M1 and M2. As a result, at the forming drum 6, the tire materials M1 and M2 can be formed into a cylindrical shape with suppressed deviations in the drum width direction, which is beneficial for manufacturing high-quality cylindrical tire components M with good productivity. In addition, as in this embodiment, when the tire components M are stacked together, the stacking offset in the drum width direction between the tire components M can be suppressed, which is beneficial for obtaining a stack of cylindrical tire components with excellent quality.

[0049] exist Figure 1In this embodiment, a conveyor 10a is positioned at one of two locations separated in the width direction, and a conveyor 10b is positioned at the other location. However, the number of conveyors 10a and 10b at each location is not limited to one; sometimes multiple conveyors (e.g., two to four) are arranged longitudinally. When multiple conveyors 10a are arranged longitudinally at one location, multiple tire materials M1 are sequentially and continuously supplied to the forming drum 6 via the longitudinally arranged conveyors 10a, and are stacked in a cylindrical shape. As described in the above embodiment, by moving the forming drum 6 relative to each conveyor 10a fixed at a predetermined position in the width direction, the sequentially supplied tire materials M1 are prevented from meandering and positioned at the reference position Px in the width direction of the forming drum 6 (in other words, the width direction position data of the tire materials M1 input to the control unit 12 is consistent with the reference value of the stored width direction position data of the tire materials M1) and are wound. That is, when multiple tire materials M1 supplied in sequence are wound around the forming drum 6 in a centered manner, the positions of the longitudinally arranged conveyors 10a are fixed, so that each tire material M1 can be continuously supplied to the forming drum 6 through each conveyor 10a.

[0050] On the other hand, in the method of centering and winding the sequentially supplied tire materials M1 around the forming drum 6 by fixing the forming drum 6 in a predetermined position and moving the conveyor 10a directly in front of the forming drum 6 in the width direction, it is impossible to transfer the tire materials M1 from the rear conveyor 10a to the front conveyor 10a while the conveyor 10a directly in front of the forming drum 6 is moving in the width direction. As a result, the supply of tire materials M1 to the forming drum 6 stagnates, resulting in extra waiting time before the centering process performed by the front conveyor 10a is completed. Accompanying this, the productivity of the cylindrical tire component M decreases. Therefore, as described above, by moving the forming drum 6 in the width direction relative to each conveyor 10a fixed at a predetermined position, and thus winding the sequentially supplied tire material M1 while suppressing its meandering positioning at the reference position Px in the width direction of the forming drum 6, excess waiting time before each tire material M1 is supplied to the forming drum 6 can be suppressed, which is beneficial to improving the productivity of the cylindrical tire component M. Similarly, when multiple conveyors 10b are arranged longitudinally at the other location, by moving the forming drum 6 in the width direction relative to the conveyors 10b fixed at a predetermined position and arranged longitudinally, and winding the sequentially supplied tire material M2 centrally around the forming drum 6, the productivity of the cylindrical tire component M is also beneficial to improve.

[0051] In this embodiment, the front ends of each conveyor 10a and 10b are positioned above the forming drum 6, but they can also be positioned below it. Alternatively, the front end of one conveyor 10a can be positioned above the forming drum 6, and the front end of the other conveyor 10b can be positioned below the forming drum 6. The number of conveyors 10a and 10b is not limited to two, but can be three or more. Furthermore, in this embodiment, each conveyor 10a and 10b is disposed on only one side of the forming drum 6 in the front-to-back direction (Y direction), but they can also be configured to be disposed on both sides. That is, in Figure 1 The system includes conveyors 10a and 10b extending in the upper region relative to the forming drum 6, but one or more additional conveyors extending in the lower region can also be added.

[0052] The forming drum 6 is not limited to the various types of forming drums known in general; for example, it can also be a so-called rigid core having an outer surface that is substantially the same as the inner surface of the manufactured tire T.
