Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method and an apparatus for attaching a reinforcing cord on a molding surface such as a drum or a belt in order to manufacture a tire or a member such as a carcass ply and a belt ply constituting the tire.
[0002]
[Prior art]
For example, a radial tire, which is currently the mainstream of pneumatic tires, has one or more carcass plies spanned between both bead portions as a reinforcing cord member, and a tread rubber. Includes a belt ply and the like disposed between them.
[0003]
In manufacturing such a tire or a member thereof, a reinforcing cord itself or a ribbon-like member including the same is attached on the drum, core, or belt forming surface to give the tire a desired performance. Various attempts have been made to form a predetermined pattern (Patent Documents 1 to 4). Various studies have also been made on methods and apparatuses for efficiently attaching tire cords (Patent Documents 3 to 5).
[0004]
Patent Document 3 discloses a device for attaching a tire cord to a sticking surface of a flat tray while changing an orientation angle. Here, the tray is fed in the longitudinal direction corresponding to the tire circumferential direction, and the cord application head is moved and moved in the tray width direction (direction between tire beads).
[0005]
Here, the cord application head includes a supply roller and a presser roller, and the running method of these roller surfaces is fixed in the tray width direction. For this reason, it is difficult to form a pattern or an arc-shaped pattern having a large angle from the tray width direction (direction between tire beads) when attaching the tire cord.
[0006]
Patent Document 4 discloses an apparatus and a method for attaching a rubber ribbon filled with short fibers onto a belt wound around a forming drum. When the forming drum is rotated at a predetermined speed, the rubber ribbon supply head is reciprocated in the width direction (drum axial direction) of the rotating drum surface. Thereby, for example, a zigzag pattern is formed over the entire width of the belt.
[0007]
Here, the supply head is made of a roller die, and prepares and sticks a cord of a rubber composition made of a short fiber material into a flat rubber ribbon. The orientation direction of the roller die itself cannot be changed, and it is considered difficult to form a complicated pattern at high speed.
[0008]
Further, Patent Document 5 discloses an apparatus for attaching a carcass cord on a molding surface of a donut-shaped core so as to span between both beads. In this apparatus, the core is rotated and the sticking is performed while moving the cord supply head along the profile of the core surface in a direction perpendicular to the core.
[0009]
Again, the roller of the cord supply head is fixed in a direction perpendicular to the running direction of the molding surface, and is not suitable for forming a complicated curve pattern.

[Problems to be solved by the invention]
In order to make the roller running direction of the cord application head variable so that the attached tire cord can form a relatively complicated pattern, the present inventor first made the cord application head rotatably supported. . In addition, a servo motor for rotating the cord application head was attached, and this was controlled by a positioning controller.
[0016]
Then, the optimum direction of the code pasting head at each position of the predetermined pattern is determined in advance by calculation. At this time, the driving speed of the molding surface and the driving speed of the cord application head were each calculated by separate positioning controllers.
[0017]
However, if arithmetic processing is performed in this way, programming processing and arithmetic processing, and further input operations become complicated, and it is efficient to apply a curved pattern including many complicated curves and bent portions. Have difficulty.
[0018]
The present invention has been made in view of the above problems, and in the method and apparatus for sticking a tire cord to a molding surface, the sticking can be performed according to a complicated curve or broken line pattern, and calculation for sticking is performed. A device capable of efficiently performing processing and input is provided.
[0019]
[Means for Solving the Problems]
In manufacturing a tire or a member thereof, the tire cord attaching method according to the present invention travels on the drum, core, or belt molding surface in a direction (X direction) substantially perpendicular to the traveling direction (Y direction). In the tire cord pasting method in which the cord pasting head is moved and moved, and in this state, a long tire cord is pasted so as to form a predetermined pattern on the molding surface, the cord pasting head sends out or pasts the tire cord. A rotation direction (θ) between the running direction (Y direction) of the molding surface and the running movement direction (X direction) of the cord application head perpendicular to the molding surface. Direction), the travel direction of the roller or guide member can be adjusted, and based on the setting input for the predetermined pattern, Automatic control of the travel drive speed of the row surface, the travel drive speed of the code pasting head, and the rotational drive speed of the cord pasting head is performed by controlling each servo motor by a single positioning controller, and in the positioning controller Then, with respect to each position of the code sticking head, the moving direction of the code sticking head from the running speed (Y direction speed vector) of the molding surface and the speed of running movement (X direction speed vector) of the code sticking head. (The direction of the combined speed vector) is obtained, and based on this, the rotational drive speed is controlled sequentially or continuously so that the traveling direction of the roller or guide member coincides with the moving direction of the cord applying head. It is characterized by.
[0020]
With the above configuration, even when sticking is performed according to a complicated curve or broken line pattern, it can be performed at high speed and efficiently, and the cost of the apparatus and labor can be minimized.
[0021]
Preferably, the control of the rotational speed is performed at a portion where the bent portion or the starting point of the predetermined pattern rotates in a pulse shape at the maximum speed of the drive motor and stops rotating at the linear portion and forms a smooth curve. , Make the rotation speed constant.
[0022]
Thereby, arithmetic processing and driving operation are further simplified, and a desired pattern can be applied efficiently and reliably. In particular, if the rotational speed is made constant, acceleration control in the X direction and the Y direction can be performed by simple setting and calculation processing, for example, by approximating the curved portion with an elliptical arc.
[0023]
According to a preferred aspect, when the first straight line and the second straight line following the first straight line are set, the transition between the first and second straight lines is performed via an arc having a preset radius. As shown, each servo motor is controlled by the positioning controller.
[0024]
With such a configuration, it is possible to smoothly perform the pasting operation at the bent portion, and it is possible to realize a fast pasting or a reduction in setting input operation burden.
[0025]
According to another preferred embodiment, in setting and inputting the predetermined pattern, the setting of the pattern in which the first and second straight line portions are connected via an arc is determined by the coordinate values of the points at both ends, This is done only by setting the coordinate value of a virtual intersection where the extended lines of the first and second straight lines intersect each other and the distance from the virtual intersection to both ends of the arc.
[0026]
In this case, the labor required for the setting input operation for the arcuate curved portion can be greatly reduced.
[0027]
The sticking device of the present invention is a cord sticking head for feeding out a tire cord so as to stick a long tire cord so as to form a predetermined pattern on a molding surface of a drum, core or belt when manufacturing a tire or a member thereof.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIGS.
[0029]
FIG. 1 is a schematic configuration diagram of a tire cord sticking device of an embodiment.
[0030]
The tire cord sticking device is for manufacturing a carcass ply, for example, and sticks the tire cord 41 to the molding surface 51 of the molding rotary drum 5 according to a predetermined pattern. In the illustrated example, the rubber sheet 6 is wound around the rotating drum 5, and the tire cord 41 is affixed thereon.
[0031]
The cord sticking head 3 includes a feeding roller 31 and a pressing roller 32, and the pressing roller 32 sticks the fed tire cord 41 on the rubber sheet 6 or directly on the molding surface 51 made of aluminum or the like.
[0032]
The tire cord 41 is made of filaments or staples made of a resin such as polyester, polyamide, or polyaramid, or a metal such as steel, and the surface thereof is covered with unvulcanized rubber before sticking.
[0033]
The rubberized tire cord 41 is wound around a bobbin 42 and set, and slack is removed and tension is adjusted by a plurality of pulleys 43. A cord sticking head passes through a guide tube of the support portion 35. 41.
[0034]
The cord application head 3 is supported in a suspended form from a support portion 35 that forms a moving element of the linear motor 22, and extends in the drum axis direction (X direction) along a horizontal rail 36 that forms a stator of the linear motor 22. Driven. That is, the cord applying head 3 is driven in the drum axis direction (X direction) by a linear motor 22 which is a kind of servo motor.
[0035]
The cord applying head 3 is rotatable about its vertical axis and is driven to rotate by a small head rotating servomotor 21 connected to the upper surface of the support portion 35.
[0036]
A single positioning controller (microcomputer device) 1 simultaneously controls the servo motor 21 for rotating the head, the linear motor 22 for moving the cord application head 3 and the servo motor 23 for driving the molding surface for rotating the rotary drum 5. Is done. That is, the positioning controller 1 has three axes in the drum axis direction (X direction), the molding surface running direction (Y direction), and the head rotation direction (θ direction) with respect to the position and posture of the cord application head 3 with respect to the molding surface 51. It is a multi-axis motion controller that controls coordinates simultaneously.
[0037]
The traveling movement of the cord pasting head 3 is performed at high speed and with high accuracy by the linear motor 22, but the servo motor 21 for rotating the head and the servo motor 23 for forming surface traveling are also made high speed by using, for example, a hollow shaft motor. Drive and control with high accuracy is possible.
[0038]
Next, the drive control system in the tire cord sticking device of the embodiment will be described with reference to FIGS. 2 to 3 are graph groups for explaining a basic method of sticking control according to a typical sticking pattern, and FIGS. It is a schematic diagram for demonstrating further.
[0039]
First, the case where it sticks according to a polygonal line pattern is demonstrated using FIG. FIG. 2 (a) shows a schematic broken line pasting pattern here.
[0040]
(1-1) When setting a polyline pasting pattern and setting a polyline pasting pattern extending from the head angle calculation start point (the origin of the graph), the coordinates (X1, Y1) of the respective bend points P1, P2. ), (X2, Y2)... Only from the input key 11 of the controller 1.
[0041]
Then, the head angle calculation mechanism 12 in the controller 1 calculates angles θ1, θ2,... Formed by the respective straight line portions forming the broken line and the tangent line of the molding surface 51 in the drum axis direction (X direction).
[0042]
In this way, control is performed so that the roller traveling direction of the cord applying head 3 always faces the moving direction of the code applying head 3 in each linear portion, that is, the direction of the vector obtained by combining the velocity vectors in the X direction and the Y direction, A method in which the head angle θ at each time point is automatically calculated from the coordinates of the start point and end point of each straight line without being input is referred to as “θ axis tangent control”.
[0043]
(1-2) Head angle adjustment (θ = 0 → θ = θ1, P = P0)
When the pasting operation is started (t = 0), first, the head rotating servo motor 21 is driven at the maximum rotational speed (θvmax), and the head angle θ reaches the angle θ1 formed by the first linear portion P0P1. The cord attachment head 3 is rotated up to this point. At this time, the position of the cord attachment head 3 remains on the starting point P0 (0, 0).
[0044]
That is, as shown in FIGS. 2C to 2E, only the rotation of the cord applying head 3 is rapidly performed in a pulsed manner with the traveling movement of the cord applying head 3 and the traveling of the drum surface 51 stopped. After that, it is stopped suddenly. For this purpose, for example, the gear mechanism can be connected and released while the servo motor 21 continues to rotate.
[0045]
(1-3) Linear movement (θ = θ1, P = P0 → P = P1)
Next, the travel of the cord applying head 3 and the travel of the drum surface 51 are started simultaneously. As a result, the cord applying head 3 moves on the straight line P0P1 as viewed from the drum surface 51. At this time, needless to say, the ratio of the traveling speed (hereinafter referred to as head traveling speed) Xv of the cord applying head 3 in the drum axis direction to the drum surface 51 traveling speed (hereinafter referred to as drum traveling speed) Yv is a straight line. It is determined by components X1 and Y1 in the X direction and Y direction in the part P0P1. That is, it is determined by the amount of movement in the X direction and Y direction in the straight line portion.
[0046]
In the example shown in FIG. 2D, the head travel speed Xv is set to be stable at a “reference speed” Xvs suitable for long-term stable operation of the linear motor 22 after the initial rise.
[0047]
(1-4) Head angle adjustment (θ = θ1 → θ = θ2, P = P1)
The acceleration / deceleration control for the traveling movement of the cord applying head 3 and the traveling of the drum surface 51 is temporarily stopped at the time when the bending point P1 is reached or just before that. That is, the supply of drive power to the linear motor 22 and the rotary drum rotating servomotor 23 is temporarily stopped. Then, the adjustment of the head angle θ similar to (1-1) is performed again.
[0048]
(1-5) Linear movement (θ = θ2, P = P1 → P = P2)
It moves on the second straight line portion P1P2 in exactly the same manner as (1-3) above. At this time, in the illustrated example, the drum surface running speed Yv is also set to “reference speed” Xvs that is suitable for long-term stable operation of the servomotor 23.
[0049]
The same applies to the straight line portion after the broken line pattern.
[0050]
Next, the case where sticking is performed according to a curve pattern including a curved line will be described with reference to FIG. FIG. 3A shows a pasting pattern of a curve composed of a straight line and an elliptical arc part (a part of the outline of the ellipse).
[0051]
(2-1) In order to set the first straight line portion P0P1 extending from the calculation start point (origin of the graph) such as the setting of the pasting pattern and the head angle etc., only the coordinates (X1, Y1) of the end point P1 of the straight line are The input key 11 is used for input.
[0052]
In addition, the elliptical arc part P1P2 following the first straight line part P0P1 is performed only by inputting the coordinate value (Xc, Yc) of the ellipse center C, the initial head angle θ2, and the coordinates of the end point P2. Here, the ellipse including the elliptical arc portion P1P2 is set in advance such that the major axis direction is either the X direction or the Y direction.
[0053]
Further, the second straight line portion P2P3 following the elliptical arc portion P1P2 is set only by inputting the coordinates (X3, Y3) of the end point P2.
[0054]
After such an input, the head angles θ1 and θ3 in the straight line portions P0P1 and P2P3 are calculated by the head angle calculation mechanism 12 in the controller 1 as in the case of the above-described broken line pattern.
[0055]
Further, the coordinate value (X, Y) at each point in the elliptical arc portion P1P2 is calculated by the arc interpolation mechanism 13, and the head angle θ at each point is calculated. Instead of calculating the coordinate values (X, Y) and the head angle θ, a differential curve may be obtained.
[0056]
(2-2) Head angle adjustment to linear movement (θ = 0 → θ1 → θ2, P = P0 → P1)
From the start of the pasting operation to the head angle adjustment at the end point of the first straight line portion P0P1, as shown in FIGS.
[0057]
(2-3) Movement along an elliptical arc and continuous adjustment of the head angle in the tangential direction (θ = θ2 → θ3, P = P1 → P2)
As shown in FIGS. 3B to 3C, while the cord applying head 3 moves on the elliptical arc portion P1P2, the head rotation speed θv is kept at a certain value which is smaller than the maximum rotation speed θvmax. . In the illustrated example, drive control is performed so as to increase at a uniform speed from the initial head angle θ2.
[0058]
As a result, as shown in FIGS. 3D to 3E, the drive control is performed so that the head travel speed Vx and the drum travel speed Vy form a sine curve having an appropriate phase.
[0059]
(2-4) Head angle adjustment to linear movement (θ = θ3 → θ4, P = P2 → P3)
The second straight line portion P2P3 following the elliptical arc portion P1P2 is exactly the same as in the case of the above-described broken line pattern.
[0060]
Next, “neighboring point passage control” used in the sticking control of the embodiment will be described with reference to FIGS.
[0061]
As shown in FIG. 4, the corner angle formed by the straight line P0P1 and the straight line P1P2 is rounded according to a certain rule to form a smooth curve.
[0062]
First, the neighborhood distance R is set, and by this, the neighborhood points C1 and C2 that are at a distance of R from the intersection P1 in each of the straight lines P0P1 and P1P2 are taken. Then, circular arcs smoothly connecting to the straight lines P0P1 and P1P2 are set at the neighboring points C1 and C2. That is, perpendicular lines are drawn from the straight lines P0P1 and P1P2 at the neighboring points C1 and C2, and an arc centered at the intersection C0 is drawn.
[0063]
Thus, by automatically replacing the corners or cusps with arcuate “neighbor passage loci”, the operation of moving the cord applying head 3 can be performed smoothly and at high speed.
[0064]
Next, using the schematic example of FIG. 5, the labor saving of the input operation by incorporating the near point passing control into the controller 1 will be described.
[0065]
When the proximity point passing control is not incorporated (command form of Comparative Example 1), the coordinates of the arc starting point P0-1 (900, 1800) and the coordinates of the arc center point (1046, 1726) are set when setting the arc portion. In addition, it is necessary to input all the coordinates (1158, 1842) of the end point of the arc.
[0066]
On the other hand, when the proximity point passing control is incorporated (command form of the embodiment), if the neighborhood distance (R = 225) is preset, only the coordinates (1000, 2000) of the virtual bending point P1 are provided. You only need to enter it. That is, as compared with the command form of Comparative Example 1, it is only necessary to perform 1/3 input operation.
[0067]
In the specific example shown in FIG. 5 (a), immediately after the input of the coordinates of the virtual bending point P1, a command for performing the neighboring point passage control (neighboring passage command) and the numerical value of the neighboring distance are input. Even in this case, the input operation is greatly reduced.
[0068]
As shown in FIG. 6, the coordinates of the center point C0 of the arc portion may be set in place of the above-described neighboring point passage control. That is, instead of setting the neighborhood distance (R = 225), it is also possible to input the coordinates (1046, 1726) of the center point C0 of the inscribed circle and the coordinates of the end point P1-2 of the arc (command form of the modified example) ).
[0069]
In the specific example shown in FIG. 6A, after inputting the coordinates of the virtual bending point P1, after inputting the command of “θ axis tangent”, the coordinates of the center point C0 and the end point P1-2 of the arc are input.
[0070]
Also in this modified example, the head angle θ at each point on the arc is automatically calculated, and based on this, rotation driving by the servo motor 21 is performed. That is, the same “θ-axis tangent control” is performed as in the case of the above-described broken line pattern. By automatically calculating the position (address position) in the XY coordinates at a predetermined point in time and the predetermined head angle θ, the head angle θ is automatically set so as to always follow the direction of the velocity vector of the cord application head. It is done.
[0071]
On the other hand, in the case of the command form of the comparative example 2 in which the head angle θ is set completely separately and sequentially calculated, as shown in FIG. And the calculation processing for obtaining the head angle must be executed separately and simultaneously.
[0072]
In the embodiment and the modification described above, the molding surface on which the sticking is performed is described as the molding surface of the molding drum. However, the molding surface on the conveyor belt may be used, and the surface of the tire molding core may be used. It may be. In addition, when pasting on the surface of the core, for example, a linear motor rail having a curved shape along the outer surface of the core can be used, and the X-direction coordinates here are on the curved rail. It can be determined as a moving distance.
[0073]
【The invention's effect】
In the method and device for attaching tire cords to the molding surface, even when applying in accordance with complicated curve and broken line patterns, it can be performed at high speed and efficiently, minimizing the cost of the device and labor. Can do.
