  Hereinafter, an embodiment according to the present invention will be described according to the attached drawings. The following description is merely illustrative in nature, and is not intended to limit the present invention, its applications, or its applications. In addition, the drawings are schematic, and ratios of respective dimensions and the like are different from actual ones.

  FIG. 1 shows a part of a groove processing apparatus for a sheet-like member 3 according to the present embodiment. The groove processing apparatus includes a first roller member 1 and a second roller member 2. Then, a groove extending in the width direction is formed on one surface of the sheet-like member 3 made of a rubber material supplied from a rubber extrusion molding die not shown. The sheet-like member 3 is conveyed by the conveyance roller 4 and then cut into an appropriate length for use.

  The sheet-like member 3 supplied from the rubber extrusion molding die is strip-like, and the thickness is different in the width direction. For example, as shown by a two-dot chain line in FIG. 2, the lower surface has a flat surface, and the upper surface has a cross-sectional shape formed of a plurality of inclined surfaces.

  The first roller member 1 is capable of rotating in the forward and reverse directions about the first shaft portion 5, and on the outer peripheral surface thereof, a plurality of ridges 6 which are arranged at a predetermined pitch in the circumferential direction and extend in the width direction are formed There is. By pressing the ridges 6 against one surface of the sheet-like member 3, grooves extending in the width direction at predetermined intervals in the longitudinal direction can be formed on the surface of the sheet-like member 3. Here, as the sheet-like member 3, a rubber material to be a side portion at the time of tire molding is used. Although not shown, the groove formed in the sheet-like member 3 functions as a degassing groove when sticking a rubber material to be a side portion to a bead filler or a carcass ply.

  Further, as shown in FIG. 3, arms 7 provided at both ends of the first shaft portion 5 are rotatably mounted about the support shaft 8 as shown in FIG. 3. As a result, the first roller member 1 is in pressure contact with the upper surface of the sheet-like member 3 by its own weight, and sandwiches the sheet-like member 3 with the receiving rollers 10 of the second roller member 2 described later.

  As shown in FIG. 2, the second roller member 2 is formed by arranging a plurality of cylindrical receiving rollers 10 in parallel so as to be capable of rotating in the forward and reverse directions about the second shaft portion 9. As shown in FIG. 4, each receiving roller 10 is disposed on the outer periphery of the elastic body 12 which can rotate around the second shaft portion 9, in which the bearing 11 is integrated with the inner peripheral surface. And a cylindrical body 13.

  The elastic body 12 is made of an elastic material such as a sponge. The elastic modulus of the elastic body 12 is sufficiently smaller than the rubber material constituting the sheet-like member 3 to be molded. Therefore, when the cylindrical body 13 is in pressure contact with the sheet-like member 3, the amount of deformation of the elastic body 12 becomes sufficiently large compared to the sheet-like member 3. Moreover, the outer peripheral surface of the elastic body 12 is formed in uneven | corrugated shape. Here, on the outer peripheral surface of the elastic body 12, a protrusion 12a having a substantially trapezoidal cross section extending in the width direction is formed at a predetermined pitch in the circumferential direction. The outer peripheral surface of the elastic body 12 is formed in a concavo-convex shape in order to secure a space in which the deformation is possible because the outer periphery is in contact with the inner peripheral surface of the cylindrical body 13.

  The cylindrical body 13 is a cylindrical metal material and is provided independently of the elastic body 12. The cylindrical body 13 prevents the elastic body 12 from directly contacting the high temperature sheet-like member 3 and prevents the elastic body 12 from being thermally deteriorated. For example, if a heat insulating structure is provided, such as coating the inner surface of the cylindrical body 13 with a heat insulating material, forming a two-layer structure with the heat insulating material, or forming the cylindrical body 13 itself with a heat insulating material, Thermal degradation of the elastic body 12 can be more effectively prevented.

  According to the groove processing device of the above configuration, when the sheet-like member 3 is conveyed, the first roller member 1 is in pressure contact with the upper surface thereof. As mentioned above, the upper surface of the sheet-like member 3 is formed in a different shape. For this reason, when the first roller member 1 is in pressure contact, the upper surface tends to be deformed flatly, and the lower surface tends to project differently according to the deformation on the upper surface side. The lower surface of the sheet-like member 3 is supported by a second roller member 2 constituted by a plurality of receiving rollers 10. Each receiving roller 10 is configured such that the elastic body 12 is accommodated inside the cylindrical body 13. Therefore, as shown in FIG. 5, each receiving roller 10 is elastically deformed individually with respect to the lower surface of the sheet-like member 3 which protrudes in the different shape, and the position of the up-down direction is displaced. As a result, when passing through the grooving device, the sheet-like member 3 can be supported in the form of a profile in which the lower surface protrudes differently, and the upper surface can be made substantially flat. And since a groove can be formed in the upper surface of sheet shaped member 3 which became approximately flat by the 1st roller member 1, regardless of the difference in thickness by the position of the width direction, the groove of predetermined depth is certainly made It can be formed.

  The sheet-like member 3 in which the groove is formed in this manner is released from the pressed state by the first roller member 1 by passing through the groove processing device, and returns to the original protruding shape. And the sheet-like member 3 (1st sheet-like member) which carried out the shape return is used by bonding together the surface in which the groove was formed on the surface of the other sheet-like member 3 (2nd sheet-like member). At this time, the first sheet-like member is sequentially pressed in the width direction, and is stuck to the second sheet-like member while being exhausted through the formed groove. As described above, the groove has a predetermined depth in which the upper surface of the first sheet member is formed flat. Therefore, when the first sheet-like member is attached to the second sheet-like member, air can be smoothly exhausted without remaining air between the first sheet-like member and the second sheet-like member. As a result, there is no internal air in the obtained member, and it is exposed as air bubbles by being accommodated in a mold and vulcanized, and there is no possibility of causing a product defect.

  In addition, this invention is not limited to the structure described in the said embodiment, A various change is possible.

  For example, in the above-described embodiment, the first roller member 1 is disposed on the upper side with respect to the sheet-like member 3 and the second roller member 2 is disposed on the lower side. is there. In FIG. 6, the second roller member 2 is disposed on the upper side of the sheet-like member 3, and each receiving roller 10 is supported so as to be movable in the vertical direction with respect to the second shaft 9. That is, an elongated hole 10a extending in the vertical direction is formed on the side surface of each receiving roller 10, and the second shaft portion 9 is capable of reciprocating the elongated hole 10a. A collar or the like (not shown) is disposed between the adjacent receiving rollers 10. Thereby, the positional relationship in the axial direction is maintained constant.

  Further, in the above embodiment, the receiving roller 10 is configured of the cylindrical body 13 and the elastic body 12 provided therein, but it is also possible to support the roller by the elastic body provided outside . For example, as shown in FIG. 7, rollers 14 corresponding to the respective receiving rollers 10 are respectively provided, and the support rods 15 for supporting the rotation shafts 14 a of the respective rollers 14 are elastically supported by springs 17 provided in the cylinder 16. Can be configured.

  Moreover, in the said embodiment, although the cylindrical body 13 of the receiving roller 10 and the elastic body 12 were provided separately, you may integrate these by sticking. The elastic body 12 is made of a sponge or the like, but may be made of a coil spring or the like. For example, as shown in FIG. 8, a plurality of springs 18 (four places) may be provided to connect the bearing 11 and the inner surface of the cylindrical body 13.

  Further, in the above embodiment, the projection is formed substantially in the shape of a gear by forming a projecting portion having a substantially trapezoidal cross section on the outer peripheral surface of the elastic body 12, but the shape is not limited to that.

  Moreover, in the said embodiment, although the center of the elastic body 12 and the cylindrical body 13 was made to correspond, both do not necessarily need to correspond.

  In the above embodiment, the receiving rollers 10 are arranged at the same height, but the height may be changed according to the thickness of the sheet-like member 3. In this case, each receiving roller 10 is preferably provided with a height adjustment mechanism capable of adjusting the height. It is further preferable that the height adjustment mechanism has a function capable of automatically adjusting the height by detecting a difference in thickness in the width direction of the sheet-like member 3.
