  In Patent Document 1, a bleeder cord of polyester spun yarn having a predetermined thickness is arranged on one side or both sides of a carcass member and / or a belt member, and an air pocket (gas body) included in a tire manufacturing process is a bleeder cord. By transmitting and absorbing the air and suppressing the hygroscopicity, the occurrence of air accumulation is suppressed, and the air entry defect is reduced.

  When pasting a bleeder cord on a treat member, it is dangerous for an operator to attach a rubber member or the like to a treat member that moves continuously on the treat transport line. When a worker attaches a common tip rubber member to the tip of multiple bleeder cords that have passed through the cord aligning means and affixes the tip rubber member to the surface of the treated treat member, the operation of the treat transport line is resumed. By continuously moving the treat member, the plurality of bleeder cords are pulled by the tip rubber member moving together with the treat member, and are arranged along the surface of the treat member by the cord aligning means. A bleeder cord that is aligned at a conversion point in the moving direction such as a downstream roller is pressed against the surface of the treat member and pasted. Go vignetting.

  When the bleeder cord is pasted on the treat member for one lot, the worker cuts the rear end portion of the bleeder cord aligned through the code aligning means with a scissors or the like while the treat transport line is in operation. It was.

Thus, conventionally, when the treat conveying line is operated and the treating member continuously moves and the bleeder cord is being fed out, the worker cuts the bleeder cord with a knife such as a scissors, Safety was not sufficiently secured.
If the operation of the treat transport line is stopped, the bleeder cord can be safely cut, but the productivity is lowered.

Is prevented from rotating.

When the sticking roll 27 swings forward, the bleeder cord C can be stuck in contact with the treating member T that is sandwiched between the sandwiching rolls 1 and 2 and moves continuously downward from above.
The bleeder cord sticking device 20 is constituted by the sticking roll 27, the roll swinging mechanism 21, the pass roll 34, the stopper rolls 35, 35 and the like.

A bleeder cord cutting device 40 is provided immediately below the pass roll 34.
The bleeder cord cutting device 40 includes a cord clamp mechanism 41 that sandwiches the bleeder cord C and a cutter 60 that is a flat plate elongated in the left-right width direction.
Five cylinders 42 are arranged on the left and right on the horizontal beam plate 16 (see FIG. 3), and the cylinder rod 43 of each cylinder 42 protrudes rearward.

  As shown in FIG. 4, the cylinder rod 43 has a rectangular flange portion 43f formed at the tip, and a shaft hole 43h drilled in the axis of the cylinder rod 43 opens at the center of the tip surface of the flange portion 43f. doing.

A clamp plate holder 45 is provided at the tip of a support rod 44 inserted and retracted into the shaft hole 43h of the cylinder rod 43. The clamp plate holder 45 clamps a movable movable clamp plate 46 that is long in the lateral direction. Hold backwards.

Note that the opening of the shaft hole 43h of the cylinder rod 43 has an increased inner diameter, and a coil spring 47 wound around the support rod 44 is inserted into the opening of the shaft hole 43h so that the bottom surface of the opening and the clamp plate It is interposed between the holders 45.
The coil spring 47 is interposed between the flange portion 43f of the cylinder rod 43 and the clamp plate holder 45 with a space therebetween.

On the flange portion 43f of the cylinder rod 43, a cutter 60 that is long in the left-right width direction is provided with its base end portion fixed and protruding rearward.
As shown in FIG. 4, when no pressing force is applied to the movable clamp plate 46 and the coil spring 47 is not compressed, the cutter 60 protruding backward projects along the upper end surface of the movable clamp plate 46. However, the front end (rear end in FIG. 4) of the cutter 60 is in a forward position slightly retracted from the clamp surface of the movable side clamp plate 46.

  Therefore, when the movable clamp plate 46 is pressed forward, the coil spring 47 is compressed and the clamp plate holder 45 approaches the flange portion 43f of the cylinder rod 43, so that the tip of the cutter 60 (the rear end in FIG. 4). Protrudes rearward from the clamp surface of the movable clamp plate 46.

At the height between the pass roll 34 and the upper cord alignment plate 15, a rear horizontal beam plate 52 is installed between the support columns 13 and 13 so as to protrude rearward on the opposite side of the cylinder rod 43. Bearing members 53 and 53 are erected on both the left and right sides of the plate 52, and a long clamp plate holder 55 is pivotally supported on the left and right bearing members 53 and 53 by a support shaft 54 in the left-right width direction.
The clamp plate holder 55 holds a fixed clamp plate 56 that is long in the left-right width direction.

A stopper member 57 protrudes upward along the front end (rear end in FIG. 4) of the rear horizontal beam plate 52, and the stopper member 57 has the clamp surface of the fixed side clamp plate 56 forward as shown in FIG. Positioning in contact with the back surface of the clamp plate holder 55 in a facing position, and positioning in contact with the back surface of the clamp plate holder 55 in a posture with the clamp surface of the fixed-side clamp plate 56 facing upward as shown in FIG. Can do.

The cord clamp mechanism 41 is in a state in which the clamp surface of the fixed side clamp plate 56 faces forward and is closed opposite to the clamp surface of the movable side clamp plate 46, and the clamp plate holder 55 is about 90 degrees. It is set in a state in which the clamp surface of the fixed-side clamp plate 56 is opened with the posture facing upward.

By the bleeder cord sticking device 20 and the bleeder cord cutting device 40 as described above, the bleeder cord C is stuck on the treat member T which is placed on the treat transport line and continuously moves downward from the sandwiching rolls 1 and 2 for each lot. Attached and disconnected.
The bleeder code C attaching process by the bleeder code applying apparatus 20 and the bleeder code C cutting process by the bleeder code cutting apparatus 40 will be described below with reference to FIGS.

First, referring to FIG. 5 showing a preparatory stage in bleeder cord sticking, the bleeder cord sticking device 20 is configured such that the roll swing mechanism 21 swings the swing arm 25 backward to separate the stick roll 27 from the treat member T. In the standby position, the sticking roll 27 is in contact with the stopper roll 35 integral with the pass roll 34, so that rotation of the sticking roll 27 in both directions is prevented.
In the bleeder cord cutting device 40, the cylinder 42 retracts the cylinder rod 43, the movable side clamp plate 46 is separated from the fixed side clamp plate 56, and the clamp surface of the fixed side clamp plate 56 is opened upward.

Here, the front end rubber member R attached commonly to the front ends of the plurality of bleeder cords C that have been pulled upward from the upper cord alignment plate 15 is attached to the upper surface of the outer peripheral surface of the sticking roll 27 at the standby position. To do.
Since the outer peripheral surface of the sticking roll 27 is formed by alternately forming a surface having a very small surface roughness and a surface having a large surface roughness in the circumferential direction, the tip rubber member R is attached to the surface having a very small surface roughness. By doing so, it does not stick firmly, slip or fall.

  In addition, since the affixing roll 27 is in a state where rotation in both directions is prevented by contacting the stopper roll 35 integral with the pass roll 34 that can rotate only in the same rotation direction, the affixing roll 27 rotates inadvertently. Thus, the attachment position of the tip rubber member R does not rotate, and therefore the tip rubber member R does not peel off.

  Here, the tip rubber member R may be attached to the sticking roll 27 as it is long over the entire width of the upper cord alignment plate 15 in which a plurality of bleeder cords C are arranged. Since it is not easy to handle, the right and left side portions of the long tip rubber member R may be gathered at the center and made short to adhere to the sticking roll 27.

Next, as shown in FIG. 5, the worker moves the movable side clamp plate 46 away from the fixed side clamp plate 56 and opens the clamp surface of the fixed side clamp plate 56 upward. The rubber tip R is attached to the surface of the fixed clamp plate 56.
The fixed-side clamp plate 56 is rotated 90 degrees around the support shaft 54 when the tip rubber member R is attached, and the tip rubber member R of the movable clamp plate 46 is attached to the clamp surface on which the tip rubber member R is attached. It is made into the closed state facing the pasted clamp surface (refer FIG. 6).

  From this state, the roll rocking mechanism 21 swings at the standby position at an appropriate timing when the tip of one lot of the treating member T moving continuously downward from the sandwiching rolls 1 and 2 has moved. The arm 25 is swung forward, and the sticking roll 27 is pressed close to the treating member T that continuously moves (see FIG. 6).

While the sticking roll 27 swings, the sticking roll 27 is rotated only in one direction by being pulled by a plurality of bleeder cords C extending from the tip rubber member R attached to the upper surface of the outer peripheral surface of the sticking roll 27. The tip rubber member R which is prevented by the adhering roll 27 allowed to adhere to the upper portion of the outer peripheral surface of the adhering roll 27 at the standby position is moved from the upper position of the adhering roll 27 while swinging to the forward pressing position. The position is naturally changed to the side position so as to be opposed to the treating member T moving downward, and the tip rubber member R is pressed by the sticking roll 27 and attached to the treating member T.
The sticking roll 27 rotates with the movement of the treating member T at this pressing position.

When the sticking roll 27 is pressed against the treating member T, the tip rubber member R attached to the upper surface of the outer peripheral surface of the sticking roll 27 is pressed against the treating member T, and the tip rubber member R is treated with a stronger adhesion. By being affixed to the member T, it moves to the treat member T.
In addition, since the outer peripheral surface of the sticking roll 27 includes a plurality of surfaces having a large surface roughness in the circumferential direction, the tip rubber member R is easily peeled off from the rotating sticking roll 27.

  When the tip rubber member R moves to the treating member T that moves continuously, the tip rubber member R is affixed to the treat member T and moves integrally, and a plurality of bleeder cords C extending from the tip rubber member R are: The upper cord aligning plate 15 is arranged and fed out, wound around a pass roll 34, pressed against the treating member T by the sticking roll 27, and a plurality of bleeder cords C are arranged in a row on the treating member T that moves continuously. It can be pasted in the state (see FIG. 7).

  In this way, the bleeder cord sticking device 20 has a roll swing mechanism 21 with a simple structure, and the swinging stick roll 27 is moved to the continuously moving treat member T without stopping the operation of the treat transport line. A plurality of bleeder codes C can be safely pasted.

  In this way, when a plurality of bleeder cords C are affixed to the treating member T for one lot and the treating member T approaches the end (starting end of the liner member), the cylinder 42 in the cord clamping mechanism 41 of the bleeder cord cutting device 40 is used. Is driven to project the cylinder rod 43, and the movable side clamp plate 46 is pressed close to the fixed side clamp plate 56 via the coil spring 47.

As shown in FIG. 8, the front end rubber member R on the fixed side clamp plate 56 and the front end rubber member R on the movable side clamp plate 46 are aligned with each other between the upper cord alignment plate 15 and the pass roll 34. The bleeder code C is sandwiched.
Even if the bleeder cord C is sandwiched between the tip rubber member R on the fixed clamp plate 56 and the tip rubber member R on the movable clamp plate 46, it is still drawn upward.

When the cylinder rod 43 further protrudes, as shown in FIG. 9, the coil spring 47 is compressed and deformed, and the movable side clamp plate 46 is pressed against the fixed side clamp plate 56 to pinch the bleeder cord C. Tension is applied to the bleeder cord C that is further drawn out, and immediately after that, the flange portion 43f of the cylinder rod 43 that compresses the coil spring 47 approaches the clamp plate holder 45, and the cutter 60 fixed to the flange portion 43f is connected to the clamp plate holder 45 and It protrudes beyond the clamping surface along the side edge of the movable clamp plate 46.
That is, the cutter 60 protrudes across the plurality of bleeder cords C drawn out from the clamping surface and applied with tension, and cuts the rear end portion of the bleeder cords C.

The cut preceding bleeder cord C is pasted to the treating member T by the pasting roll 27 up to the rear end portion, and the subsequent bleeder cord C is movable with the front end rubber member R on the fixed clamp plate 56 at the front end portion. The front end rubber member R is attached to the front end portion of the succeeding bleeder cord C by being sandwiched between the front end rubber member R on the side clamp plate 46 (see FIG. 10).
Thus, the bleeder code C is attached to the treating member T for one lot.

  Even if the bleeder code C is affixed to the treating member T for one lot, the treating member T continues to move continuously, and the treating member T of the next lot is supplied to the bleeder code attaching device 20. .

Therefore, as shown in FIG. 11, the roll swing mechanism 21 swings the swing arm 25 rearward, and the sticking roll 27 is in the standby position from the pressing position, that is, the position in contact with the stopper rolls 35, 35 at both ends of the pass roll 34. Move to.
Further, the cylinder 42 retracts the cylinder rod 43 to separate the movable side clamp plate 46 from the fixed side clamp plate 56.

  By making the surface roughness of the movable clamp plate 46 slightly larger than that of the fixed clamp plate 56, the distal rubber member R attached to the distal end portion of the subsequent bleeder cord C is easily peeled off from the movable clamp plate 46. Since it remains attached to the fixed-side clamp plate 56 having a stronger adhesion force, the clamp plate holder 55 is rotated about 90 degrees to open the clamp surface of the fixed-side clamp plate 56 with the posture facing upward. As shown in FIG. 11, the tip rubber member R attached to the clamp surface faces upward, and the worker can easily peel off the tip rubber member R.

Before the treat member T of the next lot is supplied to the bleeder cord attaching device 20, as shown in FIG. 5, the worker peels off the end rubber member R adhering to the clamp surface of the fixed side clamp plate 56 and waits. It adheres to the sticking roll 27 which is in a position and is prevented from rotating in both directions (see FIG. 5).

Then, as shown in FIG. 5, the worker attaches the tip rubber member R to the clamp surface facing the upper side of the fixed side clamp plate 56 and the clamp surface of the movable side clamp plate 46 in the open state.
Thereafter, the process shown in FIGS. 6 to 11 is repeated, and the bleeder code C can be attached to the treating member T of the next lot that has moved continuously.

In the bleeder cord cutting device 40, the cylinder rod 43, which is a pressing member of the movable clamp plate 46 among the pair of clamp plates 46, 56 sandwiching the bleeder cord C by the cord clamp mechanism 41, is subjected to compression deformation of the coil spring 47. When pressed, the cutter 60 fixed to the flange portion 43f of the cylinder rod 43 projects and cuts the bleeder cord C at the rear end portion drawn out from the clamping surface by the pair of clamp plates 46, 56. While the treat member T is moving without stopping the continuous operation, the cord clamp mechanism 41 causes the pair of clamp plates 46 and 56 to be affixed to the treat member T as the treat member T is moved and pulled out. And further, the tension is applied to the bleeder cord C that is pulled out. Despite can the cutter 60 immediately to very easily and safely cut the rear end portion drawn out from the pressing surfaces of the pair of clamping plates 46, 56 of the bleeder code C tensioned protrudes.

The cutter 60 fixed to the flange portion 43f of the cylinder rod 43 projects along the side edge of the movable clamp plate 46 from the clamping surface by the pressing of the movable clamp plate 46 to the fixed clamp plate 56 side to cut the bleeder cord C. Therefore, the cord clamp mechanism 41 is simplified by driving only the movable clamp plate 46, and the cutter 60 protrudes along the side edge of the movable clamp plate 46 only when cutting the bleeder cord C. High safety.

A tip rubber member R attached in common to the tip portions of a plurality of bleeder cords C is attached in advance to the opposing clamp surfaces of the pair of clamp plates 46, 56, and the preceding aligned bleeder cord C is attached to the tip rubber. When the rear end portion of the bleeder cord C is cut by the cutter 60 after being pinched by the members and clamped, the front end rubber member R is attached to the leading end portion of the succeeding aligned bleeder cord C, so that the preceding bleeder cord R is treated. When preparing to affix to the member T, the tip rubber member R for the subsequent bleeder cord C is attached in advance to the opposing clamp surfaces of the pair of clamp plates 46, 56, so that the treat member The attachment of the tip rubber member to the tip portion of the bleeder cord can be efficiently executed without stopping the movement.

The fixed-side clamp plate 56 is pivotally supported by a support shaft 54 oriented in the long width direction, and can rotate from a closed state facing the movable-side clamp plate 46 to an open state. With the fixed-side clamp plate 56 open, the tip rubber member R can be easily attached to the open clamp surface of the fixed-side clamp plate 56, to the clamp surfaces of the clamp plates 46 and 56 of the tip rubber member R. Can be efficiently performed.
