きた。By the way, in recent years, research has progressed to improve the strength of glass bottles, and it has become clear that the practical strength of glass bottles is only about 1/100 of the theoretical strength due to griffin flow on the glass surface. , development has been made to reduce this Griffith flow. It has also become known that one of the causes of griffin flow on the inner surface of a glass bottle is foreign matter adhering to the surface of the plunger.

面の汚れを防止するには至らなかった。For this purpose, the present inventors first invented a method of blowing out compressed air around the plunger to form an air curtain to prevent foreign matter from adhering to the surface of the plunger.
It was proposed as No.-133947. Although this method is extremely effective in preventing the adhesion of foreign matter flying from the outside, it has not been able to completely prevent the surface of the plunger from becoming contaminated.

−装置を要旨とするものである。(Means for Solving the Problems) In order to solve the above problems, the present inventors investigated the reason why even an air curtain could not prevent the adhesion of foreign matter, and as a result, they developed a positioner device for guiding the elevation of the plunger. Metal powder generated due to wear of the sliding parts of the filter gets mixed into the air for the curtain and adheres directly to the inner surface of the bottle, or gets mixed into the silicone oil and adheres to the bottle surface via the plunger. I learned that. In addition, although such metal powder cannot be completely prevented by conventionally used oils, the present invention has found that a great effect can be achieved by protecting the sliding surface of the positioner device with a wear-resistant coating. was completed based on this knowledge, and it was developed by forming a wear-resistant coating on the sliding surface of the bushing and spring guide. The gist of this paper is a positioner device for a glass molding machine that is characterized by its characteristics.
以下に本発明を図面を参照しつつ更に詳細に説明する。The present invention will be explained in more detail below with reference to the drawings.

こととなる。These wear-resistant coatings 0ω have a Kerrs hardness of 1000 or more at room temperature, and can be formed by, for example, a CVD method. Generally, each component of a positioner device is made of iron-based metal, and the wear-resistant coating aω significantly increases the wear resistance of the surface. As a result, glass powder (
Even if Hv500) or iron powder (Hv200-800) gets into the sliding surface, the wear-resistant coating 00) has a higher hardness, so the sliding surface will not be scraped off, causing metal powder. This will prevent scratches and wear from occurring. In addition, these ceramic wear-resistant coatings 00)

よりも向上させることができる。(Function) The positioner device of the present invention configured as described above has a wear-resistant coating 00) formed on at least the sliding surfaces of the bushing (+) and the spring guide (2), so that the positioner device is Even if glass powder or iron powder present inside the sliding surface enters the sliding surface, the surface will not be abraded, and therefore the generation of metal powder can be almost completely prevented. For this reason, a glass bottle molded by a glass molding machine equipped with the positioner device of the present invention can have less griffin flow on the inner surface than conventional glass bottles, and its strength can be improved compared to conventional products.

る。Further, in the positioner device of the present invention, since the sliding surface is not damaged and the initial surface roughness can be maintained for a long time, it has excellent lubricity and can be used without lubrication. Furthermore, since the positioner device of the present invention has less wear on the sliding surface, its service life can be dramatically extended.
