Definitions
- the present invention relates to a method for manufacturing a retread tire and a grinding apparatus for used tires. Specifically, the present invention is intended to realize easy and reliable grinding of tread rubber in used tires.
- Tires for automobiles are made by attaching tread rubber in contact with the road surface to the base tire, and the base tire is often worn with sufficient use even after the end of its life.
- the tread rubber portion is covered with new rubber or recycled tire raw material, and can be used again as a retread tire.
- the re-molding method hot retreading method
- the pre-curing method cold rehabilitation method
- tread rubber with a pattern that has already been vulcanized without using a mold is attached to a base tire and vulcanized in a vulcanizing can.
- a base tire is first drilled in one or more holes in the tread rubber of a used tire until it reaches the belt layer with a drill or the like, and the depth of each hole is measured manually with a scale, Next, the grinding amount of the used tire was determined based on the measured value, and the tread rubber corresponding to the grinding amount was semi-automatically or fully automatically ground by the grinding means.
- the thickness of the tread rubber of the used tire was measured manually, so it takes time and the number of measurement points is small. Had the problem of low reliability.
- Patent Documents 1 and 2 disclose a grinding apparatus capable of automatically controlling the amount of tread rubber ground on a used tire.
- the grinding device disclosed in Patent Document 1 measures the thickness of the tread rubber in the used tire by detecting the belt layer of the used tire with a metal sensor while rotating the used tire rotatably held by the holding mechanism. At the same time, the outer peripheral surface of the used tire is ground and removed by the grinding means, and the grinding by the grinding means is stopped when the thickness of the tread rubber reaches the optimum value.
- the grinding device of Patent Document 2 uses a eddy current sensor instead of the metal sensor, and measures the distance to the belt layer by the electromagnetic induction effect of the high frequency coil of the eddy current sensor brought close to the outer peripheral surface of the used tire. Calculates the thickness of the tread rubber based on the measured value, grinds and removes the outer peripheral surface of the used tire by the grinding means, and stops grinding by the grinding means when the thickness of the tread rubber reaches the optimum value. It is.
- a metal detection sensor or a eddy current sensor is used to measure the thickness of the tread rubber of the used tire, so that the belt layer is configured. If the belt cord is made of a non-metallic material such as polyester or glass fiber, the thickness of the tread rubber cannot be measured. In order to suppress, for example, when a belt reinforcing layer formed by wrapping an organic fiber such as nylon in a belt shape is embedded on the outer side in the radial direction of a belt layer formed of a steel cord, the presence of such a reinforcing layer is suppressed. Since it cannot be detected, when the tread rubber is ground, the belt reinforcing layer may be ground together with the tread rubber.
- an object of the present invention is to solve these problems, and the object thereof is not only when the belt layer is made of a cord made of a metal material but also made of a non-metal material. Even when a belt reinforcement layer made of a non-metallic material is buried outside the belt layer in the radial direction, the belt layer of the used tire is reliably detected to form a base tire of a desired shape and size There is to do.

- the “predetermined hardness” can be set based on hardness data determined in advance for each tire structure, and more specifically, data storing the tire size, the number of belts, the number of belt reinforcing layers, and the like. Can be set based on.
- a predetermined hardness within the range of the belt layer hardness and the tread rubber hardness before grinding is determined in advance, and the used tire tread rubber is removed by the grinding means. Grind and grind the tread rubber until the hardness of the tread rubber measured by the hardness measuring means reaches the above predetermined hardness, so that the desired tread rubber thickness (from the outermost surface of the belt layer to the outer peripheral surface of the tread rubber) Can be formed.
- the hardness of the tread rubber is greater than the hardness of the tread rubber before grinding, the smaller the tread rubber thickness becomes, the closer the outer peripheral surface of the tread rubber becomes to the outermost surface of the belt layer. The harder the tread rubber is, the more it becomes.
- the belt layer is detected based on the hardness of the belt layer, unlike the conventional method of detecting the belt layer using a metal detection sensor or a eddy current sensor.
- a metal detection sensor or a eddy current sensor Used even when the layer is made of a cord made of non-metallic material such as organic fiber, or when a belt reinforcing layer made of a cord made of non-metallic material such as organic fiber is embedded radially outside the belt layer The belt layer of the tire can be reliably detected.
- the second invention is a used tire in which a tread rubber located outside the belt layer in the radial direction of the used tire having a belt layer is ground and removed to constitute a retread tire tire.
- a tire grinding apparatus comprising: a grinding means for grinding the tread rubber; a hardness measuring means for measuring the hardness of the tread rubber; and a control means for controlling the grinding apparatus, wherein the control means includes the hardness measurement.
- the used tire grinding apparatus is characterized in that the grinding by the grinding means is stopped when the hardness of the tread rubber measured by the means reaches a predetermined hardness.
- the belt layer can be detected by measuring the hardness of the tread rubber of the used tire subjected to grinding by the hardness measuring means, and the tread rubber of the used tire can be detected.
- a tread rubber having a desired thickness is formed by grinding the tread rubber by the grinding means until the hardness reaches a predetermined hardness.
- the belt layer is detected based on the hardness of the belt layer, unlike the conventional method of detecting the belt layer using the metal detection sensor or the eddy current sensor.
- the layer is made of a cord made of non-metallic material such as organic fiber, or when a belt reinforcing layer made of a cord made of non-metallic material such as organic fiber is embedded radially outside the belt layer
- the belt layer of the tire can be reliably detected.
- the grinding amount of the tread rubber is preferably controlled in inverse proportion to the hardness of the tread rubber measured by the hardness measuring means.
- the used tire grinding method and grinding apparatus of the present invention not only when the belt layer is made of a cord made of a metal material, but also when the belt layer is made of a non-metal material or on the radially outer side of the belt layer. Even when a belt reinforcing layer made of a non-metallic material is embedded, the belt layer of the used tire can be reliably detected, and as a result, a base tire having a desired shape and size can be obtained.
