Here, at the time of assembling the tire rim, a tire mark is detected by a machine to match the rim characteristics with the tire characteristics.

[0008]

However, in conventional tire marking (ink method, thermal transfer method), there is a lack of area due to lack of area, such as hollow circles at the time of marking, blurring, cracking, and rubbing during transportation. When reading was not possible, or color change such as color fading with the passage of time occurred, there was a case where a machine mistakenly recognized the color.

[0009] In the hand pasting method, although there are few things as described above, hand pasting itself is extremely poor in workability and is not practical.

In view of the above facts, an object of the present invention is to provide a seal for displaying tire information and a method for attaching the tire information, which does not cause an area shortage or fading, facilitates the attaching operation, and improves the working efficiency.

[0011]

According to a first aspect of the present invention, there is provided an at least two-layer structure of a long backing sheet and a seal body disposed at a predetermined position along a longitudinal direction of the backing sheet. An adhesive that strongly adheres to the tire is applied to the opposing surface of the surface of the seal body opposite to the surface facing the mount.

According to the first aspect of the present invention, the seal body is peeled off from the mount only by pressing the seal body against the tire, so that the long mount is intermittently conveyed in the longitudinal direction.
By performing the pressing process on the seal body, automation of the sticking of the seal can be easily achieved.

According to a second aspect of the present invention, there is provided a three-layer structure comprising a long backing sheet, a seal body disposed at a predetermined position along the longitudinal direction of the backing sheet, and a protective paper covering the sealing body. The seal body is characterized in that an adhesive which is strongly adhered to the tire on the surface of the seal body facing the protection paper and which is easily peeled off from the protection paper is applied.

According to the second aspect of the invention, in addition to the effect of the first aspect, since the seal body is covered with the protective paper, there is no deterioration during storage. Further, since the protective paper can be easily peeled off from the seal body, it does not hinder automation.

According to a third aspect of the present invention, there is provided a sticking method for sticking the tire information display sticker according to the first or second aspect on a tire, wherein the mount is sent to a tire sticking position. During this feeding, the position of the seal body is recognized, the seal body whose position is recognized is positioned at the tire sticking position, and at least the seal body is pressed with a predetermined pressure to the tire sticking position. The seal body is separated from the backing sheet by a difference between the adhesive force of the sealing body and the holding force of the sealing body on the backing sheet.

According to the third aspect of the present invention, it is possible to easily position the tire at a predetermined position by recognizing the position of the seal body provided on the mount. After positioning, the seal body is pressed against the tire. The seal body adheres to the tire by this pressing, but since the adhesive force is stronger than the holding force of the seal body on the mount, the seal body and the mount are separated by separating the mount from the tire.

By sequentially repeating the above, automation of the sticking operation is realized.

[0018]

FIG. 1 shows a tire marking seal sticking apparatus 10 (hereinafter simply referred to as an apparatus 10) according to the present embodiment.
Is shown).

The present device 10 is a device for making a UB mark or a UF mark between the side surface of the tire 12, that is, between the bead portion and the crown shoulder portion, and this mark is attached as a seal. .

At the center of the apparatus 10, an air cylinder 14 is provided.
The head 16 is attached to the distal end of the telescopic rod 14A of the air cylinder 14.

The head 16 is provided so as to face the side surface of the tire 12. Also, the telescopic rod 14A
The rear end is located in a cylinder chamber in the air cylinder 14, and is provided with a partition piece that divides the cylinder chamber into two and that is movable in the axial direction of the telescopic rod 14A. The telescopic rod 14A expands and contracts due to the pressure difference between the two chambers partitioned by the partitioning piece. An electromagnetic valve 18 is attached to the base (the upper end in FIG. 1) of the air cylinder 14.

The solenoid valve 18 has an air supply port 18A and an air discharge port 18B, and has two communication ports 18 communicating with two cylinder chambers of the air cylinder 14.
C and 18D are provided.

0 and 22 are connected to the cylinder chamber, respectively. The solenoid valve 18 is selectively connected to one of the communication ports 20 (or 2).
Air can be supplied to 2), and air can be discharged from the other communication port 22 (or 20).

Thus, the expansion and contraction of the telescopic rod 14A of the air cylinder 14 can be controlled in accordance with the electric signal to the solenoid valve 18.

At the center of the telescopic rod 14A is attached a ring-shaped fixed block 24 that is prevented from moving in the axial direction. The fixing block 24 has a flange 26 extending in the left-right direction. Rods 30 are supported at the left and right ends of the flange 26 via thrust bearings 28, respectively. Therefore, the rod 3
0 is movable in a direction parallel to the telescopic rod 14A.

A holding member 32 is attached to the lower end of the telescopic rod 14A via a shaft 34. The holding member 32 has an arcuate lower end surface, and has a role of bringing the seal 36 into close contact with the side surface of the tire 12.

A retaining ring 38 is attached to the center of the rod 30. The retaining ring 38 and the thrust bearing 2
A compression coil spring 40 is attached between the compression coil springs 8. A stopper member 42 is provided at the upper end of the rod 30.

Thus, the rod 30 is held in a state where the stopper member 42 is in contact with the thrust bearing 28 by the urging force of the compression coil spring 40.

Here, the telescopic rod 1 of the air cylinder 14
4A is in the retracted state (the state of FIG. 1), the holding member 3
A slight gap is formed between the tire 2 and the tire 12 to form a passage for the seal 36. In this state, the solenoid valve 1
When the telescopic rod 14A is extended by the control of 8, the pressing member 32 can first bring the seal 36 into close contact with the tire 12 and hold it before the head 16 presses the seal 36 against the tire 12. At this time, the moving amount of the telescopic rod 14A (the amount by which the head 16 reaches the tire 12) is larger than the amount by which the pressing member 32 reaches the tire 12, so that the urging force of the compression coil spring 40 is resisted. The rod 30 is axially moved upward, and the urging force of the compression coil spring 40 corresponding to the axial movement is added to the pressing force of the pressing member 32 against the tire 12, and the seal 36 is securely held in close contact with the tire 12. Will be.

The pressing member 32 is connected to the rod 30
With respect to the axis 34, the seal 36 can be surely pressed and held on the surface of the tire 12 even if the surface shape of the tire 12 is three-dimensionally curved. I can do it.

The seal 36 is loaded on the supply reel 44 in a state of being wound up in a layered manner. The seal 36 is pulled out from the uppermost layer side thereof, and is passed through the tension roller 46 and the guide roller 48 to the right holding member 32 in FIG. 1 to the right end of FIG. The right end of the holding member 32 in FIG.
Because of the arc shape, the seal 36 is smoothly moved.

The seal 36 is attached to the left holding member 32.
Guide roller 50, tension roller 5
The reel 2 is taken up by a take-up reel 54 via the second reel 2. The left end of the left holding member 32 in FIG. 1 is also formed in an arc shape, and can move smoothly.

The tension roller 46 and the guide roller 4
8, a photoelectric conversion sensor 56 is provided.
The photoelectric conversion sensor 56 can detect the presence or absence of the notches 72 and 74 (see FIG. 2) provided in the seal 36.

The tension roller 46 peels off the protective paper 62 (see FIG. 3) constituting a part of the seal 36. The peeled protective paper 62
Is wound around the tension roller 46 (about half a turn), and is guided by the protection paper take-up reel 6 via the guide roller 64.
6 can be wound up. Therefore, at the position where the head 16 of the cylinder 14 is disposed, the seal main body 70 (both shown in FIG. 3) attached to the mount 68 is opposed to the tire 12 in a state where it is exposed downward. .

When the seal body 70 faces, the telescopic rod 14A of the cylinder 14 extends, the seal body 70 is pressed down on the tire 12 via the backing sheet 68, and the seal body 70 is attached to the tire 12. .

As shown in FIG. 2 and FIG.
Has a three-layer structure of a mount 68, a seal body 70, and a protective paper 62. An adhesive is applied to each of these mating surfaces.

A strong adhesive is applied to the seal body 70 on the protective paper 62 side. This adhesive force is strong for the tire 12, but weak for the protective paper 62. The adhesive strength between the backing sheet 68 and the seal body 70 is stronger than the adhesive strength between the protective paper 62 and the seal body 70, but has a property that the adhesive strength is weakened or eliminated after peeling.

A notch 72 is provided at one end in the width direction of the seal 36 (backing paper 68) in a position corresponding to the position where the seal body 70 is disposed, and can be detected by the photoelectric conversion sensor 56. I have. That is, the position of the seal body 70 can be recognized by detecting the notch 72 with the photoelectric conversion sensor 56.

At the other end in the width direction of the seal 36 (backing paper 68), a notch 74 indicating the remaining amount is provided. The notch 74 is provided corresponding to the final seal body 70 of the roll-shaped seal 36.
Is detected by the photoelectric conversion sensor 56, the end of the seal body 70 can be recognized.

The operation of the present embodiment will be described below. First, the seal 36 is loaded on the supply reel 44, the uppermost seal 36 (or leader tape) is pulled out, wound around the tension roller 46 and the guide roller 48, and passed under the two pressing members 32 to guide the sheet. It is wound around the roller 50 and the tension roller 52 and is hooked on the take-up reel 54.

Here, since the lower side of the pressing member 32 is slightly lifted by the urging force of the compression coil spring 40, there is a gap between the pressing member 32 and the tire 12, and the pressing member 32 can be easily passed through.

The protective paper 62 of the seal 36 drawn by the supply reel 44 is the first tension roller 46.
The protective paper 62 is wrapped around the tension roller 46 for about a half circumference,
The paper is taken up on a protection paper take-up reel 66.

When the take-up reel 54 and the supply reel 44 (and the protective paper take-up reel 66) are rotationally driven by the driving force of a driving means (not shown), first, the photoelectric conversion sensor 5 is driven.
6, the position of the seal body 70 is detected. That is, the notch 72 provided in the mount 68 is detected, but by detecting the notch 72, the distance (distance) from the detection position to the position of the head 16 is known. By the control, the seal main body can be reliably positioned at a position facing the head 16.

When the positioning of the seal body 70 is completed,
The electromagnetic valve 18 of the air cylinder 14 operates to move the telescopic rod 14A in the extending direction.

With this movement, the pressing member 32 presses the tire 12 with the seal 36 interposed therebetween. Telescopic rod 14
When A further extends, the rod 30 escapes upward against the urging force of the compression coil spring 40, and the urging force of the compression coil spring 40 is added to the pressing force on the tire 12 by the pressing member 32, The seal 36 is securely held at a predetermined position on the tire 12.

When the head 30 approaches the tire 12 and sandwiches the seal 36, a strong adhesive is applied to the surface of the seal body 70 facing the tire 12.
Is superior in adhesion to the tire 12 and is separated from the backing sheet 68 when the head 16 returns.

When the head 16 returns (when the telescopic rod 14A is retracted), the pressing member 32 is separated from the tire 12 with a slight delay.

The above is one process for attaching the seal body 70 to the tire 12, and by repeating this process, the tire 12 can be automatically attached to the seal body.

The mount 68 is sequentially wound up on the take-up reel 54, and when the end of the roll approaches the end, the photoelectric conversion sensor 5
6, a notch 74 for remaining amount recognition is detected. When the notch 74 is detected, it is recognized that the seal body 70 is the final one, and when the sticking of the seal body 70 is completed, a notification urging the replenishment of the seal 36 is performed.

As described above, since the seal body 70 is formed into a roll shape, sequentially sent to the tire application position, and pressed by the head 16 automatically, the efficiency of the conventional manual operation of the seal application is improved. Can be achieved. In addition, since the seal is used, there is no loss or the like as compared with printing, transfer, and the like, and the seal can be maintained for a long time, so that workability at the time of tire replacement can be improved.

In the present embodiment, the seal 36 having a three-layer structure is applied. However, a seal having a two-layer structure without the protective paper 62 may be used. Further, the shape of the seal body 70 is not limited to a circle, but may be another shape such as a quadrangle, and there is no limitation in color. The head 16 may be made of a hard material such as metal, or a soft material such as silicon or rubber that follows the unevenness of the tire side surface.
