Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for cleaning a tire, and more particularly, to a tire cleaning apparatus for automatically mounting a base tire for a retreaded tire or a new molded tire for a passenger car. The present invention relates to a tire cleaning method and an apparatus for automatically cleaning the inner and outer surfaces of a tire by putting the tire into a tire.

[0002]

2. Description of the Related Art Conventionally, retread tires used for trucks and buses (removing tread rubber of worn tires,
As the base tire (repaired worn tire) for a new tread rubber-covered tire), a worn tire after a complete run is generally used, the appearance of the tire is often dirty and damaged.

[0003] In addition, if only cleanly cleaned tires are not put into a retreaded tire factory, the inside of the retreaded tire factory may be contaminated, foreign matter may be mixed or adhered, and the appearance of the retreaded tire before vulcanization may be poor. May be. As such tires having poor appearance are repeatedly vulcanized, a sludge component is laminated on the mold of the vulcanizer, and the stain on the mold is promoted and the surface becomes uneven. If vulcanization is further repeated in the mold, the surface of the tire will be uneven, losing commercial value.

[0004]

Therefore, conventionally, when cleaning the base tires, the tires have to be manually taken in and out of a manual type washer, and the cleaning work has been performed.
This washing operation is only about washing with a detergent or tap water, and at present, the washing accuracy is poor and it is difficult to obtain a clean state. For this reason, dirt on the base tire stains the mold as described above, causing irregularities on the tire surface,
Since the washing water was also drained as it was, there was also a problem of environmental pollution.

In a new tire for a passenger car, a release agent is applied in a tire manufacturing process. The release agent provides a sealant layer for preventing puncture on the inner surface of the tire. In such a case, there is a problem that the sticking cannot be performed due to an obstacle, and the above-described step of removing the release agent is performed manually, but there are problems in terms of removal accuracy and productivity.

SUMMARY OF THE INVENTION It is an object of the present invention to automatically clean the inner and outer surfaces of a tire by spraying high-temperature, high-pressure washing water, so that the inner and outer surfaces of the tire can be cleanly cleaned in a short time. The release agent applied to the inner surface of the tire can be reliably removed, and the wastewater after cleaning is collected and purified, and circulated again for reuse. It is an object of the present invention to provide a tire cleaning method and a tire cleaning apparatus capable of preventing such problems.

According to the present invention, in order to achieve the above object, a tire cleaning method comprises: loading tires for cleaning, which are sequentially conveyed in a carrying-in step, into a tire cleaning device; In the tire cleaning device, high-temperature, high-pressure cleaning water is sprayed onto the inner and outer surfaces of the tire while rotating the tire to perform cleaning, and then the cleaning wastewater adhering or accumulated on the tire is suctioned and discharged, and then carried out to the next step. The gist is that.

In the tire cleaning apparatus of the present invention, a tire cleaning apparatus for cleaning an inner surface and an outer surface of a tire is provided between a step of loading the tire and a step of discharging the cleaned tire. Is a tire rotation supporting device for rotatably supporting a tire in a housing, at least one or more cleaning water spraying devices for spraying high-temperature, high-pressure cleaning water on the inner and outer surfaces of the tire, and a tire surface if necessary. A movable cleaning brush device for cleaning the
The gist of the invention is to provide a washing water suction and removal device for sucking and draining washing water attached to the tire surface after washing and washing waste water accumulated inside the tire.

The present invention is configured as described above, and in a tire cleaning apparatus, high-temperature, high-pressure cleaning water is sprayed on the inner and outer surfaces of the tire while the tire is turned to automatically perform the cleaning. The suction and drainage of the cleaning wastewater that has adhered or accumulated on the tire is carried out to the next process, so that the inner and outer surfaces of the tire can be cleaned neatly without human intervention, and the vulcanization mold can be prevented from being stained to prevent tire contamination. The product value can be improved, especially the release agent applied to the inner surface of a new tire can be reliably removed.Furthermore, the wastewater after cleaning is collected and purified, circulated again and reused. By doing so, problems such as environmental pollution can be prevented beforehand. In addition, an environment-friendly system can be obtained by recovering the solid component separated by purification and recycling it as a release agent.

The washing wastewater collected outside is supplied to the wastewater purifier 10 via the drainpipe 27, and the wastewater purifier 10 purifies oil and sludge components contained in the washing wastewater and the like. Then, the purified water is reused as washing water so as to be circulated again to the washing water.

Further, the new tire Wb having been cleaned is
Either air is dried naturally in the air or, as in the embodiment of the present invention, the drying apparatus 9 is artificially dried and automatically discharged to the next step. Thus, the new tire W
The time from the carrying in of b to the carrying out process through the washing work, drainage and drying steps can be automatically washed at a rate of about one every two to three minutes.

By automatically performing the cleaning operation of the new tire Wb by such a method, the cleaning accuracy can be improved, the appearance of the base tire Wa can be improved, and the new tire Wb can be collected in the cleaned new tire Wb. Residual water is automatically drained, eliminating the need for manual labor.
By reusing, it can be improved without harming the environment.

[0035]

According to the present invention, as described above, the loading, washing, draining, drying, and unloading of tires for cleaning are all performed automatically, and the washing wastewater is collected, purified, and washed again. Since the water is reused, the following excellent effects are obtained.

[0036] High pressure, high temperature water is automatically sprayed onto the inner or outer surface of the tire for cleaning, so the inner and outer surfaces of the tire can be cleaned neatly in a short time, the cleaning accuracy of the tire is improved, and the outer and inner surfaces of the tire are improved. As a result, the vulcanized mold can be prevented from being stained, and the commercial value of the tire can be increased. . Since the residual water accumulated in the tire after washing is automatically drained, the labor can be omitted, and the efficiency of the washing operation can be increased.

[0037] By removing pollutants from the washing wastewater after washing and recycling washing water and solid components, it is possible to create a closed system that does not emit substances that affect the environment to the outside, which can have a negative impact on the environment. Few. . Since the high-pressure and high-temperature water is sprayed by the automatic device, the cleaning can be performed in a narrow place, and at the same time, the cleaning can be performed accurately.

[0038] By automating the process, continuous cleaning becomes possible, and high productivity can be obtained. . It can be implemented without harming the environment by purifying and recycling the washing wastewater after washing.
