Description

  The present invention relates to a device for applying a strip-like sponge material that attaches a strip-like sponge material to the inner surface of a tread of a tire in the tire circumferential direction.

  Patent Document 1 below proposes an affixing device that affixes a band-like sponge material for noise control to the tire tread inner surface in the tire circumferential direction. The band-like sponge material absorbs and relaxes the resonance sound energy (vibration energy) generated in the tire lumen due to its vibration proofing property and sound absorption property, and can reduce road noise by suppressing cavity resonance.

  In this affixing device, the backing sheet is peeled off from the strip-like sponge material with backing sheet, which is continuously rewound from the sponge holding frame, using a peeling roller. And the strip | belt-shaped sponge material from which the base_sheet | mounting_paper peeled is sequentially pressed and stuck on the inner surface of a tread by a sticking roller.

  However, in the above apparatus, when the mount is peeled off from the strip-shaped sponge material with the mount, a part of the mount may be torn and adhered to the inner surface of the tread while remaining on the strip-shaped sponge material. In this case, there arises a problem that the band-like sponge material is easily detached due to insufficient adhesion.

  The present invention provides a device for applying a strip sponge material that can prevent a part of the mount from being attached to the inner surface of the tread while remaining on the strip sponge material, and can improve the paste quality of the strip sponge material. Is an issue.

The present invention is a sticking device for sticking a long strip-like sponge material with one surface as an adhesive surface in the tire circumferential direction on the inner surface of a tread that is rotatably supported,
The band-like sponge material with a mount on which the mount is arranged is wound and held in a spiral shape with the mount facing radially outward, and the band-like sponge material with the spiral mount is wound from the tip side. A sponge holding frame having an outlet for returning and taking out;
A peeling roller for peeling the mount from the strip-like sponge material with the mount taken out from the outlet;
A mount collecting means having a winding roller for winding the peeled mount;
And a sticking roller for pressing and sticking the strip-like sponge material from which the mount is peeled against the inner surface of the tread,
In addition, the mount recovery means includes detection means for detecting the presence or absence of a defective portion in the peeled mount.

  In the strip sponge material sticking apparatus according to the present invention, it is preferable that the detecting means detects the presence or absence of a defective portion between the peeling roller and the winding roller.

  In the sticking device for a strip-like sponge material according to the present invention, the detection width of the detection means is preferably 105 to 120% of the width of the mount.

  In the strip sponge material sticking apparatus according to the present invention, the detection means preferably includes a two-dimensional laser displacement sensor or an image sensor.

  In the band-like sponge material sticking apparatus according to the present invention, the detecting means sequentially calculates the length of the wound mount based on the number of rotations of the winding roller, and the mount when the sponge is held on the sponge holding frame. It is preferable to provide a comparison calculation means for comparing with the length of the backing sponge material.

  In the present invention, the detecting means detects whether or not there is a defective portion on the mount peeled from the band-like sponge material with the mount. When there is a defective portion, it can be determined that there is a high possibility that the pieces torn from the mount are stuck on the inner surface of the tread while remaining on the band-like sponge material.

  Therefore, it is possible to prevent the tire from being attached with the fragments of the mount. In the case where there is a defect portion, it is possible to take measures such as investigating the tire and removing the debris of the mount, or reattaching the entire strip-like sponge material.

It is a side view which shows the use condition of the sticking apparatus of the strip | belt-shaped sponge material of one Embodiment of this invention. It is a front view which shows the sticking apparatus of a strip | belt-shaped sponge material. It is a perspective view which shows a detection means notionally.

Hereinafter, embodiments of the present invention will be described in detail.
As shown in FIG. 1, a strip sponge material pasting device 1 (hereinafter referred to as pasting device 1) of the present embodiment is mounted on a support device 2 and rotatably supported on a tread inner surface Ts of a tire T. Then, a long strip-like sponge material 3 is attached in the tire circumferential direction.

  The support device 2 of this example includes at least traverse means 4, vertical movement means 5, and tire size adjustment means 6. The traverse means 4 moves the affixing device 1 at the reference height position Y in the tire axial direction, whereby the affixing device 1 is inserted into and removed from the bead seat hole H into the tire lumen. The vertical movement means 5 lowers the sticking device 1 inserted into the tire lumen from the reference height position Y, and sticks the strip-like sponge material 3 to the inner surface Ts of the tread. The tire size adjusting means 6 moves the traverse means 4 and the vertical movement means 5 up and down according to the size (diameter) of the tire T. Thereby, the affixing device 1 can be set at the reference height position Y determined for tires of various sizes.

  As shown in FIG. 2, the affixing device 1 includes a sponge holding frame 7, a mount collecting means 8 and an affixing roller 9, which are supported by a plate-like frame 10, for example. The frame 10 is attached to the tip of the arm 4A (shown in FIG. 1) of the traverse means 4 in an exchangeable manner.

  The band-shaped sponge material 3 is a long band-shaped body having one surface as the bonding surface S, and is held by the sponge holding frame 7 in the state of the band-shaped sponge material 3A with a mount on which the mount 11 is arranged. The strip-like sponge material 3A with the mount is cut in advance according to the circumferential length of the tread inner surface Ts.

  The sponge holding frame 7 holds the band-like sponge material 3A with a mount in a spiral shape with the mount 11 facing radially outward. The sponge holding frame 7 of this example has an annular peripheral frame portion 12 that surrounds the outer periphery of the spiral sponge material 3A with a mount.

  The peripheral frame portion 12 is provided with an outlet 13 for unwinding and taking out the spiral band-like sponge material 3A with a mount from the tip side. In this example, the take-out port 13 includes an interrupted portion 13A where a part of the peripheral frame portion 12 is interrupted, and a guide portion 13B that guides the band-like sponge material 3A with a mount from the interrupted portion 13A downward. The guide portion 13B includes a first guide plate 13B1 that guides the radially outer surface side (corresponding to the mount side) of the band-like sponge material 3A with a mount, and in this example, the first guide plate 13B1 and the radially inner surface side The case where it has 2nd guide board part 13B2 which guides is shown.

  The mount collecting means 8 includes a peeling roller 15 for peeling the mount 11 from the strip-like sponge material 3A taken out from the outlet 13, and a take-up roller 16 for winding and collecting the peeled mount 11.

  It is preferable that the peeling roller 15 is disposed at a position where an outer peripheral surface thereof is in contact with a line X extending the inner surface of the first guide plate 13B1. The take-up roller 16 is arranged in parallel with the peeling roller 15 at a position separated from the peeling roller 15. A slit 16 </ b> A (shown in FIG. 3) is formed on the outer peripheral surface of the winding roller 16 so as to hold the leading end portion of the mount 11. The take-up roller 16 is connected to a drive motor (not shown).

  The mount collecting means 8 includes a detecting means 18 for detecting the presence or absence of a defective portion K (shown in FIG. 3) in the peeled mount 11.

  As conceptually shown in FIG. 3, the detecting means 18 detects the presence or absence of the defective portion K between the peeling roller 15 and the winding roller 16 in this example. The detection width W0 in the detection means 18 is larger than the width W1 of the mount 11 and is particularly preferably in the range of 105 to 120% of the width W1.

  In this example, the detection means 18 is exemplified as having a two-dimensional laser displacement sensor 19, for example. In this example, the two-dimensional laser displacement sensor 19 is a transmissive type (for example, manufactured by Keyence Corporation) including a light emitting side sensor unit 19A that irradiates a linear sensor light L and a light receiving side sensor unit 19B that receives the sensor light L. IB series etc.) are shown. For example, the presence / absence of the defect portion K and the size thereof can be continuously measured by the width W3 of the sensor light L blocked by the mount 11. The width of the sensor light L corresponds to the detection width W0. As the two-dimensional laser displacement sensor 19, a reflection type in which the light emitting side and the light receiving side are integrated (for example, LJ-G5000 series manufactured by Keyence Corporation) can be suitably employed.

  Further, the detection means 18 may be configured to have an image sensor, particularly an illumination-integrated image sensor. In this case, it is possible to continuously measure the presence / absence of the missing portion K and the size thereof by photographing the mount 11 with an image sensor and subjecting the captured image to image processing. In the photographed video, the light from the light source is strongly reflected in the portion where the mount 11 is present, so that it becomes a white portion, and the missing portion K is dark because there is no light reflection. Therefore, an inexpensive monochrome image sensor can be suitably employed as the image sensor instead of a color image sensor.

  In addition, it is preferable that the detection means 18 has a control means (not shown) that stops the application of the band-like sponge material 3 by the application device 1 based on the detection of the presence of the defective portion K.

  Here, when the application of the band-like sponge material 3 is completed, the rear end of the mount 11 is terminated. Therefore, it cannot be distinguished from a broken portion where the mount 11 is broken in the middle. Therefore, in this example, the detection means 18 sequentially calculates the length of the wound mount 11 based on the number of rotations of the take-up roller 16, and the strip-like sponge material 3A with the mount when held by the sponge holding frame 7 is used. A comparison operation means for comparing with the length of the mount 11 (corresponding to the length of the original mount 11) is provided. Thereby, the break in the middle of the mount 11 can be detected. The number of rotations of the winding roller 16 can be measured by an encoder, for example.

  As shown in FIG. 2, the affixing roller 9 affixes the band-like sponge material 3 from which the mount 11 is peeled against the inner surface Ts of the tread. The affixing roller 9 is pivotally supported by a rod lower end of a cylinder 23 fixed to the frame 10 via a roller holder. In this example, a guide roller 17 that guides the band-like sponge material 3 from the outlet 13 to the affixing roller 9 is rotatably disposed on the frame 10.

  As mentioned above, although especially preferable embodiment of this invention was explained in full detail, this invention is not limited to embodiment of illustration, It can deform | transform and implement in a various aspect.

  In order to confirm the effect of the present invention, a pasting apparatus 1 having the structure shown in FIG. Then, 100 strip-shaped sponge materials 3A with a mount in which large and small defect portions K were intentionally formed on the mount 11 were created and pasted onto the tread inner surface Ts using the pasting device 1. And the defect | deletion part K was detected by the detection means provided in the sticking apparatus 1. FIG.

  As detection means, a transmission type two-dimensional laser displacement sensor (IB series manufactured by Keyence) and a monochrome image sensor integrated with illumination (IV-HG600MA manufactured by Keyence) were used. In any case, it was possible to detect the defective portion K for each of the 100 strip-like sponge materials with a mount 3A. No false detection.
