Abstract

The present invention relates to a rim apparatus to inspect uniformity of a tire wherein a tire is mounted on a rim of a uniformity equipment at the time of inspecting uniformity of a finished tire and, more specifically, relates to a rim apparatus to inspect uniformity of a tire which allows a finished tire to smoothly be mounted on a rim without applying a releasing agent lubricant to a tire bead portion at a time of mounting the finished tire on the rim. In the rim apparatus to inspect uniformity of the tire in accordance with the present invention, a tire bead portion (101) is placed and mounted on placement contact surfaces (2) of an upper and a lower rim (1a, 1b) to perform uniformity inspection of the tire (100). The placement contact surface formed on each of the upper and lower rims (1a, 1b) is formed on a bead placement segment (3). The bead replacement segment (3) is integrally fixated to a segment module (4). The segment module (4) is provided with a slider (6) moving forwards and backwards along a linear guide (5), and is connected to each of the upper and lower rim bodies (8) through contraction/expansion links (7).

Description

[0001] The present invention relates to a rim apparatus for tire uniformity test,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a rim apparatus for testing uniformity of a tire in which a tire is mounted on a rim of a uniformity apparatus during uniformity testing of the finished tire, To a rim device for testing uniformity of a tire which can be smoothly mounted and separated in a rim without performing lubricant application of release agent to the bead portion.

Typically, a tire that has undergone a vulcanization process during the manufacture of a tire is completed through an expansion process, a trimming process, and a repair process, and the finished tire is finally subjected to an inspection process before being put into a warehouse.

The uniformity test, which is one of the inspection processes of the finished tire, measures whether or not the semi-finished products of the tire used for manufacturing the tire are made uniformly positioned.

Conventionally, the uniformity equipment used in the tire uniformity test measurement is designed to measure the force variation in the longitudinal direction and the lateral direction of the tire while mounting the tire on the upper and lower rims and rotating the tire while the tire is being inflated.

When the tire is mounted on the upper and lower rims of the uniformity facility in the conventional uniformity test of the finished tire, the lubricant of the releasing agent is first applied to the tire bead portion using the application roller, and then the tire bead portion, So that the smooth tires can be engaged and separated.

However, there is a problem in that a measurement error may occur in the tire uniformity test because deviation in measurement data may occur due to unevenness of application amount of the release agent lubricant applied to the tire bead portion and lubricant application time.

Korean Patent Publication No. 10-2012-0017179 (Feb. 28, 2012) Japanese Patent Publication No. 04210642 (Oct. 31, 2008)

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above problems occurring in the prior art, and it is an object of the present invention to provide an apparatus and a method for mounting a tire on upper and lower rims of a uniformity apparatus, And the tire bead portion is smoothly mounted on or separated from the upper and lower rims using pneumatic pressure.

In order to accomplish the above object, the present invention provides a tire uniformity inspection rim apparatus in which a tire bead is seated on a seating contact surface of upper and lower rims provided in a uniformity facility to perform a uniformity inspection of a finished tire, And the segment module is provided with a slider which moves forward and backward along a linear guide, and which is provided with a linkage for contracting / expanding the linkage to the bead inner wear segment And are installed on the upper and lower rim bodies, respectively.

Further, in the present invention, the body of the upper and lower rims is provided with a pneumatic passage for supplying or exhausting pneumatic pressure to the inside of the mounted tire.

The rim device for testing the uniformity of tires according to the present invention is characterized in that when the tires are mounted on the upper and lower rims of the uniformity facility for the inspection of the uniformity of the finished tire, the tires are smoothly and accurately applied to the upper and lower rims It is possible to perform the uniformity inspection measurement, thereby improving the reliability of the measurement data by measuring the uniformity.

1 is a sectional view showing a rim apparatus for tire uniformity inspection according to the present invention,
2 is an enlarged sectional view of the main part of Fig.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments described above, but various modifications may be made without departing from the scope of the present invention.

FIG. 1 is a cross-sectional view showing the upper and lower rims in the tire uniformity inspection system according to the present invention. FIG. 2 is an enlarged cross-sectional view of the main part of FIG. 1. In the present invention, The tire 100 is mounted between the rims 1a and 1b to perform uniformity inspection.

The present invention is characterized in that the tire bead 101 is mounted on the seating contact surface 2 of the upper and lower rims 1a and 1b to perform the uniformity test of the tire 100 as shown in the figure Wherein the seating contact surface 2 formed on each of the upper and lower rims 1a and 1b is formed on the bead inner wear segment 3 and the bead inner wear segment 3 is formed on the segment module 4 And the segment module 4 is provided with a slider 6 moving forward and backward along the linear guide 5 and connected to the upper and lower rim bodies 8 via the shrinking / .

Each of the upper and lower rim bodies 8 has a width control for expanding and contracting the upper and lower rims 1a and 1b and a pneumatic passage 9 for feeding pneumatic or pneumatic exhaust into the tire 100.

The slider 6 moves forward and backward along the linear guide 5 fixedly mounted on the rim body 8 to assist in moving the segment module 4 and the bead seat wearing segment 3 back and forth .

The shrinking / expanding link 7 serves to guide the forward and backward movement of the segment module 4 provided with the bead inner wearing segment 3, and the bead inner wearing segment 3 is provided with a bead- A seating contact surface 2 on which a fitting 101 is seated is formed.

1, the bead inner segments 3 of the upper and lower rims 1a and 1b before the tire 100 is inserted into the uniformity facility are formed to have a diameter smaller than the diameter of the bead 101 of the tire 100, It is in a standby state that is reduced to a small size.

1, the upper and lower rims 1a and 1b are inflated, that is, when the tire 100 is inflated, the air pressure is supplied through the air passage 9 in the direction of arrow As the bead inner wear segment 3 is expanded in the linear guide 5 under the guidance of the contraction / expansion link 7 while the slider 6 advances in the direction of the arrow C, (101) smoothly fitting to the seating contact surface (2) of the bead seat wearing segment (3).

Then, the tire 100 mounted on the upper and lower rims 1a and 1b of the uniformity facility is rotated while uniformly testing the load by applying a load.

On the other hand, when the tire 100 is separated from the upper and lower rims 1a and 1b, when the air pressure is discharged through the air passage 9 in the direction of the arrow B, the bead- The diameter of the tire 100 is reduced such that the tire 100 is detached from the seating contact surface 2 of the bead inner-wear segment 3.

The diameters of the upper and lower rims 1a and 1b are kept in a standby state until the next tire to be loaded is mounted.

The above-mentioned rim apparatus for tire uniformity inspection according to the present invention is mounted on a tire bead to which upper and lower rims are fitted without lubricant oil application, and performs uniformity inspection. It is possible to obtain more accurate inspection measurement data regardless of the application amount or the application position.
