Since the cutter part moves ``ζ'' following the movement, there is a problem in that it accelerates the wear of the cylinder piston part, etc.

置を提供するものである。This invention was devised by paying attention to the conventional problems, and its purpose is to maintain the pressure contact force of the cutter device at a constant pressure so as to prevent formation on the tire surface during finishing. To provide a tire finishing device which effectively prevents characters, designs, etc. from being scraped off, and which prevents a large load or wear from being applied to a lifting device that supports a cutter device.

を要旨とするものである。In order to achieve the above object, the present invention supports a cutter device on a base plate supported by an elevating device via a link mechanism so as to be swingable in the tangential direction of the tire, and provides a buffer between the base plate and the cutter device. The gist of this is that a device has been installed.
以下添イ１図面に基いて、この考案の実施例を説明する

。Further, the link mechanism 3 supporting the cutter device 5 includes two link arms 7 and a diagonal 8 connected to the tip of the link arm 7.
a and 8b, and the thread end of the link arm 7 is rotatably connected to bearings 9a and 9b installed near one edge and the other edge of the base plate 2, and a joint 85 connected to the tip. , 8b are swingably connected to the bottom of both ends of the cutter device 5 in the longitudinal direction. Said Ji9
- The inputs 1 to 8a, 8b are configured as spherical bearings so as to be able to swing around the center in the tangential direction of the tire W, and are capable of following the curvature of the tire surface in the direction perpendicular to the cutter. Therefore, the cutter device 5 is supported by a parallel link constituted by two link arms 7, a joint 8 connected to their tips, and hesprays 1 and 2, as shown in FIG. . As a result, the cutter device 5 can always move parallel to the base plate 2 with respect to the radial displacement of the tire W. Therefore, if the base plate 2 is aligned with the tangential direction of the tire W, the cutter device 5 can Regardless of the displacement of W in the radial direction, the tangential direction is always maintained and the horizontal state is maintained while moving up and down.

As mentioned above, the loose insertion device 4 is composed of two curved leaf springs arranged in a direction perpendicular to the longitudinal direction of the cutter device 5.
A buffer device 4 is provided to support the cutter device 5 with a constant buffering force.

Consisting of two canter bolts 13a and 13b supported in a U-shaped space y++1r via a support plate 12, and a cutter portion 15 fixed between the bolts 13a and 13b via screws 14. The cutter boulders 13a, 13)+ and the cutter portion 15 are connected to the tire W.
'C is arranged linearly with respect to the tangential direction.

１・接線方向の変位は無視できる。When the tire W is rotated from this state and the firmness that occurs during molding is started, the shearing force of the vent and the frictional force between the cutter part 15 and the surface of the tire W are in the tangential direction of the tire W. to work. This tangential force acts on the link arm 7 as a tensile force, but since the link arm has sufficient strength and the angle between the link arm 7 and the base plate 2 is small, the tie of the cutter section 15 is −
1. Displacement in the tangential direction can be ignored.

Cutter part 15° Cutter frame 10. Cutter boulder 13a, 13b pawn base plate 2
Since the cutter portion 15 is sufficiently smaller than when the movable portion includes the cutter portion 15 in the movable portion, the cutter portion 15 can follow the tire surface very well.

Because of the interposition, it is lightweight and it is possible to press the cutter device against the tire with a weaker pressing force than before.As a result, it is effective for scraping off letters and designs formed on the tie-1 surface during finishing processing. can be prevented.
