Definitions
- the present invention relates to a method and an apparatus for manufacturing glass bulbs such as bulbs, mercury lamps and the like, physical and chemical containers such as beakers and flasks, tableware such as tumblers and teapots, and hollow glass articles such as inner glass of magic bottles. Things.
- a hollow glass article is manufactured by a blowing machine
- a predetermined amount of molten glass that is intermittently supplied from a feeder connected to a glass melting furnace is shaped into a disc, and the rotary table of the machine body is formed.
- the molten glass hangs from the circular hole of the support ring while rotating the support ring, the molten glass is placed in a mold and blown. Air is blown through the head to form a hollow glass article of a desired shape.
- the molded hollow glass article is connected to an annular foil on the support ring which has been stopped at the intended position, so that when removing the hollow glass article, the foil is cut off. I'm taking it out. Disclosure of the invention
- glass powder is generated at the time of cutting the coil, and the glass powder enters into the hollow glass article immediately after blowing, and needs to be cleaned in a later step. Therefore, they could be welded and become defective.
- a device was required to rotate the heavy supporting ring and to stop the rotation by positioning it accurately.
- An object of the present invention is to make it possible to take out a hollow glass article without cutting the foil, to prevent glass powder from dropping and adhering into the hollow glass article due to the cutting of the foil, and to rotate the blow head.
- An object of the present invention is to provide a method and an apparatus for manufacturing a hollow glass article in which a special device is not required for stopping and positioning.
- a first method of the present invention is to supply a disk-shaped molten glass onto a support ring, lower a blow head onto the support ring, and reduce the blow head on the support ring.
- the molten glass in a disk shape is directly supplied below the blow head, the blow head is lowered, and the periphery of the molten glass is held by the blow head. After holding, the blown head blows air to form a hollow glass article, and after forming, releases the holding by the blow head and takes out the hollow glass article.

- the second device of the present invention is arranged so as to be movable up and down around the rotary table, and directly receives and holds the periphery of the molten glass formed into a disk shape from the lower gop mold through the holding means.
- the disk-shaped molten glass is once supplied onto a support ring, and the molten glass on the support ring is held by a blow head to form the support ring. Since the blow molding is performed with the blown glass article removed, the hollow glass article can be taken out by releasing the holding of the blow head without cutting the mould integral with the blown hollow glass article. it can.
- the support ring in the first method is omitted, and the molten glass in a disk shape is directly supplied below the blow head to be held by the blow head.
- blow molding is performed, so if the blow head is held open without releasing the blow head, it is possible to release the hollow gas without cutting the mo- les integrated with the blown hollow glass material. A lath article can be taken out.
- the first apparatus of the present invention is configured such that the support ring can be removed during the blow molding by the retracting means, and the blow head has a means for holding the disk-shaped molten glass around the blow ring.
- the first method can be easily performed because the foil does not have to be cut when the hollow glass article is taken out.
- the second apparatus of the present invention can directly receive and hold a disc-shaped molten glass from a gob-forming lower mold by a blow head, thereby simplifying the apparatus and also providing a hollow glass article.
- the second method can be easily implemented because the foil does not have to be cut at the time of removal.
- the hollow glass article can be taken out without cutting the moil after molding, so that the glass powder can be prevented from entering the hollow glass article.
- the same effect as that of the first aspect of the invention can be achieved by omitting the support ring.
- the invention of claim 1 can be easily implemented.
- the second aspect of the present invention can be easily implemented, and the whole of the provisioning machine can be simplified.
