Description

ガラスびん成形機Glass bottle forming machine
　本発明は、プレスアンドブロー方式によりガラスびんを成形する場合に用いられるガラスびん成形機に関する。 The present invention relates to a glass bottle forming machine used when a glass bottle is formed by a press and blow method.
　プレスアンドブロー方式によりガラスびんを成形する場合には、プレスでパリソンを粗型成形した後にブロー（圧縮空気の吹き込み）で仕上型成形する。粗型７を用いてパリソンＰを成形する場合には、図５に示すように、まず粗型７にゴブＧを投入した後、この粗型７の上部をバッフル８で蓋をし、例えばエアーシリンダ（図示せず）の駆動によってプランジャ１を上昇させて、ゴブＧをプレスすることにより、このゴブＧを粗型７、バッフル８、口型６、ガイドリング６ａに密着させてパリソンＰを成形するようにしている。 When forming a glass bottle by the press and blow method, after the parison is roughly molded by a press, finish molding is performed by blowing (blowing compressed air). When the parison P is formed using the rough mold 7, as shown in FIG. 5, first, the gob G is put into the rough mold 7, and then the upper portion of the rough mold 7 is covered with a baffle 8, for example, air The plunger 1 is raised by driving a cylinder (not shown), and the gob G is pressed to bring the gob G into close contact with the rough mold 7, the baffle 8, the mouth mold 6, and the guide ring 6a to form the parison P. Like to do.
　その後、バッフル８が上昇し、粗型が開き、図６に示すように、パリソンを保持している口型６をメカニズム９で反転し、パリソンＰを仕上型内に移動し、仕上型が閉じる。さらに、仕上型の上方から圧縮空気を吹き込み、ガラスびんの最終成形を行う。成形が完了すると、仕上型が開き、ガラスびんが取り出され、徐冷、検査などが行われる。 Thereafter, the baffle 8 is raised, the rough mold is opened, and as shown in FIG. 6, the mouth mold 6 holding the parison is reversed by the mechanism 9, the parison P is moved into the finishing mold, and the finishing mold is closed. . Further, compressed air is blown from above the finishing mold to perform final molding of the glass bottle. When molding is completed, the finishing mold is opened, the glass bottle is taken out, and gradually cooled, inspected, and the like.
　パリソンをプレス成形するプランジャ１は、３つの位置（ポジション）をとることができる。図５の左側に示すのは、いわゆるローディングポジションで、プランジャ１がこの位置にあるときに、ゴブＢが粗型７内に投入される。図５の右側に示すのは、いわゆるアップポジションで、プランジャ１がローディングポジションからアップポジションに上昇することで、ゴブＢからパリソンＰがプレス成形される。図６に示すのはいわゆるダウンポジションで、パリソンの成形が完了した後、プランジャ１がアップポジションからダウンポジションに降下し、パリソンを保持している口型６をメカニズム９で反転し、パリソンＰを仕上型内に移動する。このときプランジャ１がダウンポジションにあることで、反転移動する口型とプランジャ１とが接触することがない。 The plunger 1 for press-molding the parison can take three positions. The left side of FIG. 5 shows a so-called loading position. When the plunger 1 is in this position, the gob B is thrown into the rough mold 7. The right side of FIG. 5 shows a so-called up position, in which the plunger 1 is raised from the loading position to the up position, and the parison P is press-molded from the gob B. FIG. 6 shows a so-called down position. After the parison molding is completed, the plunger 1 descends from the up position to the down position, the mouth mold 6 holding the parison is inverted by the mechanism 9, and the parison P is Move into the finishing mold. At this time, since the plunger 1 is in the down position, the mouth mold that moves in reverse and the plunger 1 do not contact each other.
　図８は、従来のガラスびん成形機における、パリソンを成形するプランジャ装置の断面説明図である。プランジャ１の基部にはエアシリンダ（図示せず）のシリンダロッド１ａが接続され、エアシリンダの作動に伴うシリンダロッド１ａの上下動に従って、プランジャ１が上下動する。 FIG. 8 is a cross-sectional explanatory view of a plunger device for molding a parison in a conventional glass bottle molding machine. A cylinder rod 1a of an air cylinder (not shown) is connected to the base of the plunger 1, and the plunger 1 moves up and down as the cylinder rod 1a moves up and down as the air cylinder operates.
　プランジャ１の基部の外周にはインナースリーブ２が嵌め込まれ、プランジャ１はインナースリーブ２の内部に沿って摺動可能である。インナースリーブ２の上端部が口型６内のガイドリング６ａ内に入り込み、プランジャ１とガイドリング６ａの中心が一致するように構成されている。 The inner sleeve 2 is fitted on the outer periphery of the base portion of the plunger 1, and the plunger 1 can slide along the inner sleeve 2. The upper end portion of the inner sleeve 2 enters the guide ring 6a in the mouth mold 6 so that the centers of the plunger 1 and the guide ring 6a coincide.
　インナースリーブ２は外筒３の内部にあり、インナースリーブ２は外筒３の上部内面に沿って摺動可能である。インナースリーブ２の上下方向中間部の外周にはフランジ部２ａが形成され、該フランジ部２ａと外筒３内周面から内側に環状に膨出する支持部３ｃの間に、コイルスプリング４が設けられ、これによってインナースリーブ２は上方に付勢されている。 The inner sleeve 2 is inside the outer cylinder 3, and the inner sleeve 2 can slide along the upper inner surface of the outer cylinder 3. A flange portion 2a is formed on the outer periphery of the intermediate portion in the vertical direction of the inner sleeve 2, and a coil spring 4 is provided between the flange portion 2a and a support portion 3c that bulges inwardly from the inner peripheral surface of the outer cylinder 3. Thus, the inner sleeve 2 is biased upward.
　図８に示すプランジャ１の位置はローディングポジションで、エアシリンダは作動しておらず（ニュートラル状態）、インナースリーブ２はコイルスプリング４によって上方に押し付けられ、フランジ部２ａの上面が外筒３の当接面３ｂに当接し、プランジャ１基部はインナースリーブ２下端から内側に環状に膨出する支持部３ｃに支持されて浮いた状態（プランジャ及びシリンダロッドの重量が支持部３ｃに支持されている状態）になっている。 The position of the plunger 1 shown in FIG. 8 is the loading position, the air cylinder is not operating (neutral state), the inner sleeve 2 is pressed upward by the coil spring 4, and the upper surface of the flange portion 2 a is in contact with the outer cylinder 3. Abutting against the contact surface 3b, the plunger 1 base is floated by being supported by a support 3c that bulges inwardly from the lower end of the inner sleeve 2 (the weight of the plunger and cylinder rod is supported by the support 3c) )It has become.
　パリソンを成形するためのプランジャアップポジションは、図８の状態からエアシリンダ（図示せず）が作動してシリンダロッド１ａ及びプランジャ１が上昇する。口型が反転移動するためのダウンポジションは、アップポジションからエアシリンダ（図示せず）が作動してシリンダロッド１ａ及びプランジャ１が降下し、図８に示すようにプランジャ１基部がインナースリーブ２下端の支持部３ｃに接触するが、シリンダロッド１ａ及びプランジャ１は更に下降し、これにつれてインナースリーブ２もコイルスプリング４の力に逆らって、下端が支持部３ｃに接触するまで下降する。その後、エアシリンダはニュートラル状態となり、シリンダロッド１ａ及びプランジャ１はフリーになりコイルスプリング４の力で図８のローディングポジションに戻る。 In the plunger up position for forming the parison, the air cylinder (not shown) is operated from the state shown in FIG. 8, and the cylinder rod 1a and the plunger 1 are raised. The air cylinder (not shown) is actuated from the up position to lower the cylinder mold 1a and the plunger 1 so that the mouth mold is reversely moved. As shown in FIG. 8, the base of the plunger 1 is the lower end of the inner sleeve 2. The cylinder rod 1a and the plunger 1 are further lowered, and the inner sleeve 2 is also lowered against the force of the coil spring 4 until the lower end comes into contact with the support portion 3c. Thereafter, the air cylinder enters a neutral state, the cylinder rod 1a and the plunger 1 become free, and return to the loading position shown in FIG.
　このようなプレスアンドブロー方式によるガラスびん成形機は、例えば下記特許文献１、２などに開示されている。 Such a press and blow type glass bottle molding machine is disclosed in, for example, the following Patent Documents 1 and 2.

　本発明者らは、ガラスびん成形の際に発生するいくつかの欠陥は、パリソン成形時にゴブを粗型投入するときのプランジャの位置、すなわちローディングポジションに関係することを発見した。以下、この点を図７に基づいて説明する。 The inventors of the present invention have found that some defects generated during glass bottle molding are related to the position of the plunger when the gob is inserted into the rough mold during parison molding, that is, the loading position. Hereinafter, this point will be described with reference to FIG.
　図７において、上段左側の図は粗型７内にゴブＧが投入され、プランジャ１はローディングポジションにある。プランジャのローディングポジションが低いため、ゴブＧの上部（ゴブＧとバッフル８の間）に多くのエアが存在している。図７の上段右側の図は、左側の状態からプランジャ１がやや上昇してゴブＧが持ち上げられたところである。この段階ではゴブはまだプレスされておらず、ゴブの上部にはエア溜まり１２ができやすい。図７下段の図は、プランジャ１がさらに上昇してアップポジションとなり、パリソンＰのプレス成形が完了した状態である。このように、ゴブは、プランジャの上昇に伴って一旦上昇した後、プレスが開始されてガラスが粗型内を下方に移動していくため、粗型の下方においてはガラスとの接触が遅れ、ガラス温度が下がって低温部Ｐａが生じる。一方粗型の上部では、エア溜まりによって金型とガラスの接触が不良で温度が下がらない高温部Ｐｂが生じる。 In FIG. 7, the upper left figure shows the gob G in the rough mold 7 and the plunger 1 is in the loading position. Since the loading position of the plunger is low, there is a lot of air in the upper part of the gob G (between the gob G and the baffle 8). The figure on the right side of the upper stage of FIG. 7 shows the position where the plunger 1 is slightly raised from the left side state and the gob G is lifted. At this stage, the gob has not been pressed yet, and an air reservoir 12 is easily formed on the upper part of the gob. The lower part of FIG. 7 shows a state where the plunger 1 is further raised to the up position and the press forming of the parison P is completed. In this way, the gob rises once with the rise of the plunger, and then the press is started and the glass moves downward in the rough mold, so the contact with the glass is delayed under the rough mold, The glass temperature is lowered and a low temperature portion Pa is generated. On the other hand, in the upper part of the rough mold, a high temperature portion Pb is generated in which the contact between the mold and the glass is poor due to air accumulation and the temperature does not decrease.
　このように、プランジャのローディングポジションが低いと、パリソンの温度ムラが大きくなる。このようなパリソンをブロー（圧縮空気の吹き込み）で仕上型成形するとパリソンの膨れ方が不均一になり、ガラスびんの肉厚不良となる。また、ゴブは、プランジャの上昇に伴って一旦上昇した後、プレスが開始されてガラスが粗型内を下方に移動していくため、プレスが遅れ、その分ガラス温度が下がり（ガラスの流動性が悪くなり）プレス圧力を高くする必要があるが、プレス圧力を高くすると型の合い目線が顕著に出る「合い目不良」や、表面の微細なクラックである「びり」が生じやすくなる。 Thus, when the plunger loading position is low, the temperature variation of the parison becomes large. When such a parison is finish-molded by blowing (injecting compressed air), the parison swells unevenly, resulting in poor thickness of the glass bottle. In addition, the gob rises once with the rise of the plunger, and then the press is started and the glass moves downward in the rough mold, so the press is delayed and the glass temperature is lowered accordingly (the glass fluidity). It is necessary to increase the press pressure. However, if the press pressure is increased, the “joint defect” in which the mold line of the mold becomes noticeable and “chatter” which is a fine crack on the surface is likely to occur.
　図５はプランジャのローディングポジションを高くした場合の説明図である。同図左側は、粗型７内にゴブＧが投入され、プランジャ１はローディングポジションにある。プランジャのローディングポジションが高いため、ゴブＧの上部（ゴブＧとバッフル８の間）のエアはきわめて少ない。したがって、粗型の上部にエア溜まりは生じにくい。図５の右側はプランジャ１が上昇してアップポジションとなり、パリソンＰのプレス成形が完了した状態である。このように、エア溜まりができにくく、しかもプランジャのローディングポジションが高く、プランジャの上昇開始とほぼ同時にガラスのプレスが始まるので、ガラス温度の低下が少なくなり、肉厚不良、合い目不良、びりなどの欠点の発生が減少する。 FIG. 5 is an explanatory diagram when the loading position of the plunger is increased. On the left side of the figure, the gob G is inserted into the rough mold 7, and the plunger 1 is in the loading position. Due to the high loading position of the plunger, there is very little air above the gob G (between the gob G and the baffle 8). Accordingly, air accumulation is unlikely to occur in the upper portion of the rough mold. The right side of FIG. 5 shows a state where the plunger 1 is raised to the up position, and the press molding of the parison P is completed. In this way, air accumulation is difficult, and the plunger loading position is high, and the glass press starts almost simultaneously with the start of the plunger lift, so the glass temperature decreases less, poor wall thickness, poor joints, chatter, etc. The occurrence of defects is reduced.
　本発明は、パリソン成形におけるローディングポジションを高くして、ガラスびんに発生する肉厚不良、合い目不良、びりなどの欠点を減少させることを目的とするものである。 The object of the present invention is to increase the loading position in parison molding and reduce defects such as defective thickness, poor joint, and chatter that occur in glass bottles.

The present invention is a glass bottle molding machine that presses a parison by raising a plunger inserted into an opening of a mouth mold and a guide ring provided in a lower part of a rough mold,
The plunger is raised and lowered by an air cylinder,
An inner sleeve is provided between the plunger and the outer cylinder, the inner sleeve is urged upward by a coil spring provided around the outer peripheral portion, and is slidable in the outer cylinder.
The plunger is slidable within the inner sleeve, and a support portion bulging inward is formed at the lower end of the inner sleeve, and a coiled spring spacer surrounds the outer periphery of the base portion of the plunger. Placed,
In the loading position, which is the position of the plunger when the gob is thrown into the rough mold, the inner sleeve is in a predetermined raised position by the pushing force of the coil spring, and the plunger base is supported by the spring spacer and floats. The state
In the down position, which is the position of the plunger when the mouth mold holding the parison is reversed, the inner sleeve is lowered by the air cylinder to the predetermined lowering position against the pushing force of the coil spring, and the plunger is moved to the inner sleeve. In contrast, the glass bottle forming machine is characterized in that the spring spacer is lowered and is lowered to the lower surface of the plunger base so that the spring spacer is contracted low.
　本発明のガラス成形機は、プランジャのローディングポジションを高くして、肉厚不良、合い目不良、びりなどの欠点の発生を抑制することができる。
　すなわち、インナースリーブ内において、プランジャがスプリングスペーサの上に支持されるので、ローディングポジションがスプリングスペーサの高さだけ高くなる。また、ダウンポジションにおいては、プランジャはインナースリーブに対しても相対的に降下し、スプリングスペーサがその高さが低くなるように収縮するので、プランジャのローディングポジションを高くした割にはダウンポジションにおけるプランジャ位置が低くなり、口型の反転移動の邪魔にならないようにすることができる。 The glass molding machine of the present invention can increase the loading position of the plunger and suppress the occurrence of defects such as poor thickness, poor joint, and chatter.
That is, since the plunger is supported on the spring spacer in the inner sleeve, the loading position is increased by the height of the spring spacer. Also, in the down position, the plunger also descends relative to the inner sleeve, and the spring spacer contracts so that its height is lowered. The position can be lowered so that it does not interfere with the mouth-shaped reversal movement.
　本発明のガラス成形機は、従来の同種のガラス成形機のインナースリーブ内にスプリングスペーサを取り付けた構造であるので、従来のガラス成形機を容易に改造して本発明ガラス成形機とし、プランジャのローディングポジションを高くして欠点の発生を減少させることができる。プランジャのローディングポジションを高くした割にはダウンポジションにおけるプランジャ位置が低くなるので、通常、インナースリーブの上下動する範囲（ストローク）が大きくなるような改造を行う必要がない。 Since the glass molding machine of the present invention has a structure in which a spring spacer is attached to the inner sleeve of a conventional glass molding machine of the same type, the conventional glass molding machine can be easily modified to form the glass molding machine of the present invention. Increasing the loading position can reduce the occurrence of defects. Since the plunger position in the down position is lower for a higher plunger loading position, it is not usually necessary to make modifications to increase the range (stroke) of the inner sleeve to move up and down.
　本発明のガラス成形機は、ローディングポジションを高くしてガラスびんに発生する肉厚不良、合い目不良、びりなどの欠点を減少させることができる。また、プランジャのローディングポジションを高くした割にダウンポジションにおけるプランジャ位置が低くなるので、通常、インナースリーブ２の上下動のストロークを大きくする必要がなく、従来のガラス成形機を改造して本発明ガラス成形機とすることも容易である。 The glass molding machine of the present invention can increase the loading position and reduce defects such as defective thickness, poor joint, and chatter that occur in glass bottles. Further, since the plunger position in the down position is lowered while the plunger loading position is increased, it is not usually necessary to increase the vertical stroke of the inner sleeve 2, and the conventional glass forming machine is modified to make the glass of the present invention. It is also easy to make a molding machine.

発明の実施するための形態BEST MODE FOR CARRYING OUT THE INVENTION
　図１～３は、本発明ガラス成形機の実施形態におけるパリソンを成形する部分の概略断面図である。図１はプランジャ１がローディングポジションにあるとき、図２はアップポジションにあるとき、図３はダウンポジションにあるときを示している。 1 to 3 are schematic cross-sectional views of a portion for forming a parison in an embodiment of the glass forming machine of the present invention. FIG. 1 shows the plunger 1 in the loading position, FIG. 2 shows the up position, and FIG. 3 shows the down position.
　プランジャ１の基部にはエアシリンダ（図示せず）のシリンダロッド１ａが接続され、エアシリンダの作動に伴うシリンダロッド１ａの上下動に従って、プランジャ１が上下動する。プランジャ１の基部の外周にはインナースリーブ２が嵌め込まれ、プランジャ１はインナースリーブ２の内部に沿って摺動可能である。インナースリーブ２の上端部が口型６内のガイドリング６ａ内に入り込み、プランジャ１とガイドリング６ａの中心が一致するように構成されている。インナースリーブ２は外筒３の内部にあり、インナースリーブ２は外筒の上部内面に沿って摺動可能である。インナースリーブ２の上下方向中間部の外周にはフランジ部２ａが環状に突出形成され、該フランジ部２ａと、外筒３内周面から内側に環状に膨出する支持部３ｃの間に、コイルスプリング４がインナースリーブ２の外側で外筒３の内側に設けられ、これによってインナースリーブ２は上方に付勢されている。 The cylinder rod 1a of an air cylinder (not shown) is connected to the base of the plunger 1, and the plunger 1 moves up and down as the cylinder rod 1a moves up and down as the air cylinder operates. An inner sleeve 2 is fitted on the outer periphery of the base portion of the plunger 1, and the plunger 1 can slide along the inside of the inner sleeve 2. The upper end portion of the inner sleeve 2 enters the guide ring 6a in the mouth mold 6 so that the centers of the plunger 1 and the guide ring 6a coincide. The inner sleeve 2 is inside the outer cylinder 3, and the inner sleeve 2 is slidable along the upper inner surface of the outer cylinder. A flange portion 2a is formed annularly on the outer periphery of the intermediate portion in the vertical direction of the inner sleeve 2, and a coil is formed between the flange portion 2a and a support portion 3c that bulges inwardly from the inner peripheral surface of the outer cylinder 3. A spring 4 is provided outside the inner sleeve 2 and inside the outer cylinder 3, whereby the inner sleeve 2 is biased upward.
　図１～３のガラスびん成形機が図８の従来の成形機と異なるのは、スプリングスペーサ５を有する点で、その他は全く同じである。インナースリーブ２の下端には内側に環状に膨出する支持部３ｃが形成され、支持部３ｃ上にコイル状のスプリングスペーサ５がプランジャ１の基部の外周を取り巻くように載置され、プランジャ１の基部は、スプリングスペーサ５の上に載置されている。 The glass bottle molding machine shown in FIGS. 1 to 3 is different from the conventional molding machine shown in FIG. A support portion 3c that bulges inwardly is formed at the lower end of the inner sleeve 2, and a coiled spring spacer 5 is placed on the support portion 3c so as to surround the outer periphery of the base portion of the plunger 1. The base is placed on the spring spacer 5.
　図４はスプリングスペーサ５の断面図である。スプリングスペーサ５は、断面が長方形の細長い板状体をコイル状に捲回したものである。上段は力が作用していない自然の状態、下段がダウンポジションにおける収縮した状態である。 FIG. 4 is a cross-sectional view of the spring spacer 5. The spring spacer 5 is obtained by winding an elongated plate-like body having a rectangular cross section into a coil shape. The upper stage is a natural state where no force is applied, and the lower stage is a contracted state in the down position.
　図１のプランジャ１の位置はローディングポジションで、エアシリンダは作動しておらず（ニュートラルの状態）、インナースリーブ２はコイルスプリング４の押し上げ力によって上方に押し付けられ、フランジ部２ａの上面が外筒３の当接面３ｂに当接している。また、プランジャ１はスプリングスペーサ５の押し上げ力によって保持されている（プランジャ及びシリンダロッドの重量がスプリングスペーサ５の押し上げ力に支えられている）。図１のプランジャのローディングポジションは、図８の従来成形機におけるプランジャのローディングポジションよりもスプリングスペーサ５の高さだけ高くなっている。 The position of the plunger 1 in FIG. 1 is the loading position, the air cylinder is not in operation (neutral state), the inner sleeve 2 is pressed upward by the pushing force of the coil spring 4, and the upper surface of the flange portion 2a is the outer cylinder 3 is in contact with the contact surface 3b. The plunger 1 is held by the pushing force of the spring spacer 5 (the weight of the plunger and the cylinder rod is supported by the pushing force of the spring spacer 5). The plunger loading position in FIG. 1 is higher than the plunger loading position in the conventional molding machine in FIG. 8 by the height of the spring spacer 5.
　図２は、パリソンを成形するため、図１の状態からエアシリンダ（図示せず）が作動してシリンダロッド１ａ及びプランジャ１がアップポジションに上昇した状態である。このときインナースリーブ２の位置は図１の位置と変わりない。 FIG. 2 shows a state in which an air cylinder (not shown) is operated from the state of FIG. 1 and the cylinder rod 1a and the plunger 1 are raised to the up position in order to form a parison. At this time, the position of the inner sleeve 2 is not different from the position of FIG.
　図３は、図２の状態からエアシリンダ（図示せず）が作動してシリンダロッド１ａ及びプランジャ１がダウンポジションに降下した状態である。プランジャ１が降下すると、先ずプランジャ基部の下面がスプリングスペーサ５上端に当接し、スプリングスペーサ５の高さが低くなるように収縮させ、さらにコイルスプリング４を下方に変形させながらインナースリーブ２を押し下げる。ついには、インナースリーブ２下端は支持部３ｃに当接して降下を停止し、スプリングスペーサ５は図４の下段に示すように縮んだ状態になる。 FIG. 3 shows a state in which an air cylinder (not shown) is operated from the state of FIG. 2 and the cylinder rod 1a and the plunger 1 are lowered to the down position. When the plunger 1 descends, first, the lower surface of the plunger base comes into contact with the upper end of the spring spacer 5, contracts so that the height of the spring spacer 5 becomes lower, and further pushes down the inner sleeve 2 while deforming the coil spring 4 downward. Finally, the lower end of the inner sleeve 2 comes into contact with the support portion 3c to stop the lowering, and the spring spacer 5 is contracted as shown in the lower part of FIG.
　図３のプランジャダウンポジションにおいて、口型６は成形したパリソンを保持した状態で、メカニズム９によって仕上型に反転移動する。このとき、口型６（又はガイドリング６ａ）の内面下端は鎖線矢印の軌跡を移動するが、プランジャ１に接触することはない。 In the plunger down position of FIG. 3, the mouth mold 6 is reversely moved to the finishing mold by the mechanism 9 while holding the molded parison. At this time, the lower end of the inner surface of the mouthpiece 6 (or the guide ring 6a) moves along the locus of the chain line arrow but does not come into contact with the plunger 1.
　図１～３の実施態様は、従来の成形機にスプリングスペーサ５を取り付け、プランジャのローディングポジションを３／８インチ高くした。これにより、パリソンのプレス終了時間が約１０°（ガラスびんの成形１サイクルを３６０°とした場合）早くなり、肉厚不良、合い目不良、びりなどの欠点で排除されていたガラスびんの数は約２５％減少した。 In the embodiment shown in FIGS. 1 to 3, the spring spacer 5 is attached to a conventional molding machine, and the plunger loading position is increased by 3/8 inch. As a result, the press finish time of the parison is increased by about 10 ° (when one cycle of glass bottle forming is 360 °), and the number of glass bottles that have been excluded due to defects such as defective thickness, poor joint, and chatter. Decreased by about 25%.
