Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a tire tape applicator, and more specifically, a decorative white ribbon or white letter or the like painted in the circumferential direction of the sidewall of the tire. The present invention relates to a tire tape automatic sticking machine for protecting and for preventing the portion from becoming dirty during transportation.

(Prior Art) Conventionally, in order to protect the decorative white ribbons and white letters that have been painted in the circumferential direction of the sidewall portion on the side of the tire, and to prevent that portion from becoming dirty during transportation, white Work is in progress to attach tape to ribbons and white letters.

In the pasting work, a worker has pasted one end of the tape onto a part of the white ribbon of the tire and then, while rotating the tire, sequentially pasted the tape onto the side surface of the tire having a certain curvature.

However, as mentioned above, the tape was applied all by hand, so the work efficiency was extremely poor, and the tape was peeled off because the tape had a certain curvature on the outside in the circumferential direction. There was a problem that I could not do it.

(Purpose of the Invention) The present invention was devised by focusing on the conventional problems, and the purpose is to improve the workability by automatically applying the tape, and to make it optional. The present invention provides a tire tape applicator capable of reliably adhering a tape on the outer side and the inner side in the circumferential direction even in a tire having a curvature of.

(Structure of the Invention) In order to achieve the above object, the present invention is a crimping means for sequentially crimping a tape in a circumferential direction on a side portion of a rotatable turntable to which a tire is detachably mounted, in a predetermined position on the side surface of the tire. It is possible to move back and forth and adjust the angle freely,
The gist of the present invention is to provide crimping assisting means for sequentially crimping the inner side in the circumferential direction of the tape adhered by the crimping means to the side of the crimping means.

(Embodiment of the Invention) An embodiment of the invention will be described below with reference to the accompanying drawings.

FIG. 1 is a vertical cross-sectional view of a tape applying machine 100 embodying the present invention, and FIG. 2 is a partial plan view of FIG. 1. This tape applying machine 100 is a tire support for rotatably supporting a tire W. The apparatus 10 and a sticking mechanism 50 for sticking the tape T on the side surface of the tire W along the circumferential direction.

As shown in FIG. 1, the tire support device 10 includes a rotary drive shaft 13 through a bearing 12 on a side portion of a support frame 11.
Is rotatably supported in the vertical direction.
A turntable 15 having a plurality of mounting bolts 14 for attaching a rim for fixing the tire W to the tip of the turntable 15
Is fixed horizontally, and the rear end of the rotary drive shaft 13 is connected to a geared motor 18 via a sprocket 16a, a chain 17, and a sprocket 16b.

Further, the tape attaching mechanism 50 includes the support frame 1
It is supported by a frame 51 extending upward. The tape attaching mechanism 50 includes a pressure-bonding means 52 such as a pressure-bonding rubber roller for bonding the tape T (bonding tape) to the tire W.
An advancing / retreating mechanism 53 for advancing / retreating the crimping means 52 with respect to the tire W, an angle adjusting mechanism 54 for adjusting the crimping angle of the crimping means 52, and a circumferential inner side of the tape T pasted by the crimping means 52. And a pressure assisting means 55 such as a soft urethane roller for sequentially pressure-bonding, and a reel 56 around which a tape T is wound is provided on the side of the pressure-bonding means 52 as shown in FIG.

The tape T is attached to the tire W by coating it in the circumferential direction of the sidewall portion of the tire W or on the formed white ribbon or white letter for decoration.

The advancing / retreating mechanism 53 is provided at the tip of the slide plate 57,
The crimping means 52 is rotatably supported via a shaft 58, and the lower portion on the rear end side is slidably supported by a guide rod 60 of a guide plate 59 via a ball bush 61. The guide plate 59 is the frame 51
Is rotatably supported by a pin 51a, and a base end portion 63 of an operation cylinder 62 (air cylinder) is rotatably supported by a pin 64 on an upper surface of a rear end side of the guide plate 59. Has been done.

A screw rod 66 is attached to the tip of the rod 65 of the operation cylinder 62.
Is mounted on the slide plate 5
It is screwed into a nut 67 rotatably supported on the shaft 7.

Therefore, when the operation cylinder 62 is expanded and contracted, the slide plate 57 slides along the guide plate 59, and at the same time, the crimping means 52 attached to the tip of the slide plate 57 advances and retreats toward the tire W. By rotating the nut 67 with the handle 68, the crimping means 52 on the slide plate 57 can be moved back and forth along the screw rod 66 while finely adjusting the angle with respect to the tire W.

Next, the crimping assisting means 55 such as the brush or the soft urethane roller is arranged on the side of the crimping means 52, and the upper end side of the sidewall W1 of the tire W is crimped by the crimping means 52 as shown in FIG. The inside of the tape T is pressure-bonded to the formed tape T by the pressure-bonding assisting means 55.

That is, as shown in FIGS. 4 and 5, first, one end of the adhesive tape T is attached onto a white ribbon, a white letter or the like formed on the sidewall portion W1 of the tire W, and the pressure bonding angle and When the tire W is rotated in a fixed direction while being pressed by the pressure-bonding means 52 whose pressure-bonding position has been adjusted, the outer circumferential direction of the tape T is sequentially pulled out from the reel 56 by the rotational force of the tire W and attached to a predetermined position. To go. Further, from the rear side of the crimping means 52, the inner side in the circumferential direction of the tape T is crimped by the crimping assisting means 55, and the tape T is circularly formed on the sidewall portion W1 of the tire W having a constant curvature surface by one rotation of the tire W, And it can be applied evenly.

The crimping force of the crimping assisting means 55 is adjusted so that the inside of the tire W becomes stronger, and the tape T
It is possible to effectively prevent the inside of the peeling.

(Effect of the Invention) This invention advances and retreats the pressure-bonding means for sequentially pressure-bonding the tape in the circumferential direction on the side portion of the rotatable turntable on which the tire is detachably mounted as described above. Since the tape is attached freely and the angle can be freely adjusted, and the side of the pressure-bonding means is provided with pressure-bonding auxiliary means for sequentially pressure-bonding the inner side in the circumferential direction of the tape bonded by the pressure-bonding means. Therefore, the workability is significantly improved compared to the conventional manual work performed by workers, and even with tires having an arbitrary curvature, the tape can be reliably applied to the outside and inside in the circumferential direction. There is an effect that can be.
