Description
【０００１】
【発明の属する技術分野】
本発明は、ガラス製コップの底面に彫刻模様を形成する方法に関するものである。
【０００２】
【従来の技術】
ガラス製コップなど中空ガラス製品の成形方法については、一般的にはＨ−２８マシン等の自動成形機を用いて行われているのは周知である。この成形機におけるコップ底面への模様の刻印は、粗型へ予め彫刻を入れておくか、底型で成形する方法がとられている。
【０００３】
ところが、粗型へ予め彫刻を入れて成形する場合、彫刻の範囲が狭くコップ底径の二分の一程度が限度であり、また彫刻の凹凸の表現は殆ど不可能で、０．２〜０．３ｍｍの凹凸での表現しか出来なかった。また、底型に予め彫刻を入れておいて底型で成形する場合は、大きな凹凸の表現のみであり、細かい線や点の表現は不可能である。
【０００４】
【発明が解決しようとする課題】
本発明は上記のような課題を解決して、ガラス製コップの底面に１〜２ｍｍの凹凸をもたせた細かい柄模様を表現し、コップ底径の二分の一を越える大きな柄模様を表現したガラス製コップを安価に提供することにある。
【０００５】
【課題を解決するための手段】
上記のような課題を解決するために本発明では、Ｈ−２８マシン等の成形機で成形後、徐冷炉に入るまでのガラスがまだ高温の状態の時、コップの底面をバーナーで加熱し、軟らかくなったコップ底面に彫刻を施したスタンプをコップの底にプレスする事によりコップの底面に彫刻模様を形成する方法であって中空ガラス製品の底面を上にした状態でバーナーで加熱する工程と、ベルトコンベアー上で製品を一時的に停止させ製品を保持する工程と、彫刻を施したスタンプを中空ガラス製品の底にプレスして中空ガラス製品の底面に１〜２ｍｍの凹凸をもたせた彫刻模様を形成する工程を含む底面にコップ底径の二分の一を越える彫刻模様を形成したことを特徴とする。
【０００６】
【発明の実施の形態】
以下に、本発明の好ましい実施の形態を図を用いて説明する。
図１に全体の工程を示すが、まずＨ−２８マシン等の成形機でモイル付き半製品を成形し、その半製品はバーン・オフ・マシンに搬入され、モイルと言われる上の不要なヘタ部分をカットオフし、残ったコップ形状の口部となるカット面をバーナーで焼き、カット面を丸くする所謂口焼きをした後に製品はバーン・オフ・マシンからテークアウトされ、徐冷炉に通じるコンベアに乗せられる。ここまでの工程は従来行われている方法と同じである。バーン・オフ・マシンからテークアウトされ、徐冷炉に通じるコンベアに底面を上向きに乗せられたコップの底面は高温ではあるが、ガラスの軟化点以下の温度に下がっているため、底面を軟化点以上に加熱する必要があり、コンベアから底焼きマシンに搬入され、底焼きマシン内に取付けられたガスバーナーで底面を軟化点以上の温度まで赤熱し、底面を軟化状態にする。底面を加熱したコップは再び徐冷炉に通じるコンベアに底面を上向きに乗せられ、スタンプメカと言われるスタンプマシンまで移動する。スタンプメカの構造を図２に示すが、スタンプメカに移動したコップは光センサーで感知し、コンベア上のコップ２の移動を停止し保持するためのストッパー３が閉じる。ストッパー３の開閉は、光センサーからの信号によりエアーシリンダー５が作動して行なわれる。ストッパー３で保持されたコップ２の真上に取り付けられた彫刻を施したスタンプ１は、それと連結したエアーシリンダー４により上下動する機構になっているが、スタンプ１が下降して、コップ２の底面センターにスタンプ１を押さえつけ、コップ２の底面に彫刻模様を刻印する。スタンプ後スタンプ１が上昇した後、ストッパー３が開きコップ２はコンベア上を流れて徐冷炉に搬入される。この動作を繰り返すことでコップの底面に彫刻模様を刻印した製品を連続生産することが出来る。
【０００７】
【実施例】
従来から行われているＨ−２８マシンでモイル付き半製品を自動成形し、バーン・オフ・マシンで不要なモイル部分をカットし、口焼き加工して口外形６２ｍｍ，底径５５ｍｍ、全長１３０ｍｍの台付きコップ形状に仕上げたのち、底面を上向きにして徐冷炉に通じるコンベアに乗せた。このコンベア上を底焼きマシンまで移動し、その底焼きマシンで底面をバーナーで底面温度９００〜９５０℃に加熱して再びコンベア上にもどした。底焼きされた製品がスタンプメカの所まで移動した時ストッパーで停止、保持される。ストッパーで製品が保持された後、図３に示したようなエンゼルフィシュを彫刻したスタンプを取り付けたスタンプマシンが下降して、まだ高温で軟らかい製品底面にスタンプをプレスすることで、図４のような彫刻模様が底面に刻印された。底面に刻印された彫刻模様は元のスタンプの彫刻模様を忠実に再現し、エンゼルフィシュのヒレや海草の１ｍｍ程の細いラインも明瞭に表現することが出来た。また、底径に対する彫刻模様の大きさは７０％以上を占め、従来製品に見られない広範囲の柄表現をした製品が得られた。
【０００８】
【発明の効果】
以上の説明から明らかなように、本発明の方法によればＨ−２８マシンの粗型あるいは底型に予め彫刻模様を入れて成形した場合に比して、非常に細かな１〜２ｍｍの凹凸の有る柄を底面の広範囲に表現することが出来、底面に彫刻模様の入った特色のある製品を大量に提供することが可能となった。よって、本発明は従来の問題点を解決した底面彫刻模様入りグラスとして提供でき、産業の発展に寄与するところは極めて大である。

BACKGROUND OF THE INVENTION
The present invention relates to a method for forming a sculpture pattern on the bottom surface of a glass cup.
[0002]
[Prior art]
It is well known that a method for forming a hollow glass product such as a glass cup is generally performed using an automatic molding machine such as an H-28 machine. In order to engrave a pattern on the bottom surface of the cup in this molding machine, a rough mold is engraved in advance or a bottom mold is used.
[0003]
However, when a rough mold is preliminarily engraved and molded, the range of engraving is narrow and is limited to about one-half of the cup bottom diameter, and it is almost impossible to express the unevenness of the engraving. I could only express it with 3mm unevenness. In addition, when engraving the bottom mold in advance and molding with the bottom mold, it is only representation of large irregularities, and it is impossible to represent fine lines and dots.
[0004]
[Problems to be solved by the invention]
The present invention solves the above-mentioned problems, expresses a fine pattern with a 1 to 2 mm irregularity on the bottom of a glass cup, and expresses a large pattern exceeding one-half of the cup bottom diameter. The purpose is to provide a low-cost cup.
[0005]
[Means for Solving the Problems]
In order to solve the above-described problems, in the present invention, when the glass is still in a high temperature after being molded with a molding machine such as an H-28 machine, the bottom surface of the cup is heated with a burner to be soft. A method of forming a sculpture pattern on the bottom surface of the cup by pressing a stamp that has been engraved on the bottom surface of the cup, and heating with a burner with the bottom surface of the hollow glass product facing up, A process of temporarily stopping the product on the belt conveyor and holding the product, and a stamped stamp on the bottom of the hollow glass product to form a sculpture pattern with 1 to 2 mm of unevenness on the bottom of the hollow glass product A sculpture pattern exceeding one-half of the cup bottom diameter is formed on the bottom including the forming step.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
Fig. 1 shows the entire process. First, a semi-finished product with a foil is formed by a molding machine such as an H-28 machine, and the semi-finished product is carried into a burn-off machine. Cut off the part, burn the cut surface that becomes the cup-shaped mouth part with a burner, round the cut surface, so-called mouth-cooking, the product is taken out from the burn-off machine and passed to the slow cooling furnace Can be put on. The steps so far are the same as the conventional methods. The bottom of the cup, which is taken out from the burn-off machine and placed on the conveyor leading to the slow cooling furnace with the bottom facing upward, is hot, but has dropped to a temperature below the softening point of the glass. It is necessary to heat, and it is carried into the bottom baking machine from the conveyor, and the bottom surface is heated to a temperature higher than the softening point by a gas burner attached in the bottom baking machine, and the bottom surface is softened. The cup that has heated the bottom surface is again placed on the conveyor that leads to the slow cooling furnace with the bottom surface facing upward, and moves to a stamp machine called a stamp mechanism. The structure of the stamp mechanism is shown in FIG. 2. The cup moved to the stamp mechanism is detected by an optical sensor, and the stopper 3 for stopping and holding the movement of the cup 2 on the conveyor is closed. The opening and closing of the stopper 3 is performed by operating the air cylinder 5 by a signal from the optical sensor. The engraved stamp 1 attached directly above the cup 2 held by the stopper 3 has a mechanism that moves up and down by an air cylinder 4 connected to the stamp 1. Press the stamp 1 to the bottom center, and engrave the engraving pattern on the bottom of the cup 2. After stamping, stamp 1 rises, stopper 3 opens, and cup 2 flows on the conveyor and is carried into a slow cooling furnace. By repeating this operation, products with engraved engravings on the bottom of the cup can be produced continuously.
[0007]
【Example】
Semi-finished products with moils are automatically formed with the conventional H-28 machine, unnecessary moils are cut with a burn-off machine, and baked to create an outer diameter of 62 mm, a bottom diameter of 55 mm, and a total length of 130 mm. After finishing the cup-shaped cup, it was placed on a conveyor leading to the slow cooling furnace with the bottom facing up. It moved to the bottom baking machine on this conveyor, the bottom face was heated to the bottom temperature of 900-950 degreeC with the burner with the bottom baking machine, and it returned on the conveyor again. When the bottom-baked product moves to the stamp mechanism, it is stopped and held by a stopper. After the product is held by the stopper, the stamp machine with the stamp engraved with angelfish as shown in Fig. 3 descends and presses the stamp on the bottom of the product that is still soft at high temperature, as shown in Fig. 4 A sculpture pattern was engraved on the bottom. The sculpture pattern engraved on the bottom faithfully reproduced the original sculpture pattern of the original stamp, and was able to clearly express the thin line of 1 mm of angelfish fins and seaweed. In addition, the size of the sculpture pattern relative to the bottom diameter accounted for 70% or more, and a product with a wide range of pattern expression not found in conventional products was obtained.
[0008]
【The invention's effect】
As is apparent from the above description, according to the method of the present invention, the unevenness of 1 to 2 mm is very fine as compared with the case where the engraving pattern is previously formed in the rough or bottom mold of the H-28 machine. This makes it possible to express a large number of distinctive products with engraving patterns on the bottom. Therefore, the present invention can be provided as a glass with a bottom sculpture pattern that solves the conventional problems, and contributes greatly to the development of the industry.
