本発明はガラスビン胴部の強度検査装置に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a strength testing device for the body of a glass bottle.
炭酸飲料用ガラスビンのような使用時に大きい
内圧のかかるガラスビンは、製壜工場においてそ
の全数に対して強度検査を行なう必要がある。こ
のために従来から種々の強度検査装置が用いられ
ているが、胴部に強度上の欠陥のあるビンを高速

44766号、特公昭52−14991号公報等に示されてい
るように、ガラスビンの進行径路を挾んでその胴
部を押圧する手段を設け、ビンを半径方向に押圧
してこれによる応力に耐えられないビンを破壊さ
せる形式のものがよく知られている。 Glass bottles, such as glass bottles for carbonated beverages, which are subjected to large internal pressures during use, must undergo strength tests on all of them at bottle factories. For this purpose, various strength inspection devices have been used in the past, but the one that can easily remove bottles with strength defects in the body at high speed is the
As shown in Japanese Patent Publication No. 44766 and Japanese Patent Publication No. 52-14991, a means is provided to press the body of the glass bottle by sandwiching its travel path, and the bottle is pressed in the radial direction to withstand the stress caused by this. A well-known type is one in which bottles are destroyed.
これらの従来装置は第３図に示したようにビン

ンは排除することが不可能である。 As shown in Fig. 3, these conventional devices are configured to uniformly press the body of the bottle by bringing a pressing means supported parallel to the outer surface of the bottle into contact with the entire body of the bottle. The purpose of this is to generate uniform tensile stress on the outer surface of the bottle. However, when a bottle is inspected using this conventional device, the results of investigating the maximum tensile stress generated in each part of the bottle are as shown in Figure 4, and a large stress is generated in the center part D of the body, but in B. , C, and E, and if the pressing force is set to generate the allowable stress value at point D, B, C,
It can be seen that only stress far below the allowable value is generated in parts such as E. That is, the conventional apparatus can only remove bottles that have a strength defect in the center of the barrel, but cannot remove bottles that have defects in the upper or lower part of the barrel.
本発明はこのような従来装置の欠点を解決する
ためになされたものであつて、押圧手段の少なく
とも一方にガラスビンの胴上部と胴下部とに接す

たことを特徴とするものである。 The present invention has been made in order to solve the drawbacks of such conventional devices. The glass bottle is characterized in that one of the glass bottles is swingably supported in the axial direction of the glass bottle.
以下に本発明を図示の実施例に基づいて更に詳

欠き正面図、第２図はその平面図である。 The present invention will be explained in more detail below based on illustrated embodiments. FIG. 1 is a partially cutaway front view of the device of the embodiment, and FIG. 2 is a plan view thereof.

平軸８から等距離にある。 As shown in the drawing, a glass bottle 1 to be inspected is traveling along a straight path by a conveyor 2, and a cylindrical pressing means 3 and a concave cylindrical pressing means 4 are placed between them on this traveling path. is provided. The cylindrical pressing means is rotated at a constant speed by a motor (not shown) around a vertical shaft 5 fixed to the machine base, and the other pressing means 4 is rotated by a piston rod 7 of an air cylinder 6 fixed to the machine base. is attached to the tip of the glass bottle via a horizontal shaft 8 so as to be swingable in the axial direction of the glass bottle. and pressing means 3
Projections 9 and 10 are formed on the circumferential surface of the glass bottle 1 to contact the upper and lower body parts of the glass bottle 1, and protrusions 11 and 12 are formed on the inner peripheral surface of the pressing means 4 at the same height. . These protrusions may be formed integrally with the pressing means as shown, or a strip made of a suitable elastic material such as urethane may be attached to the circumferential surface of the pressing means. Note that the protrusions 11 and 12 are equidistant from the horizontal axis 8.
このように構成されたものは、従来の装置と同
様にガラスビン１を押圧手段３と４との間に挾み
つつエアシリンダ６により押圧手段４を押し出し
てビン１を押圧するものであるが、突条９〜１２
は何れもビンの胴上部と胴下部とに接するように
形成されているので、ビンはこれらの部分でのみ
荷重を受けることとなる。しかも押圧手段４は水
平軸８によつてその軸線方向に揺動自在に支持さ
れているので突条１１と１２には等しい荷重が作
用する。 In the device constructed in this way, the glass bottle 1 is sandwiched between the pressing means 3 and 4 and the pressing means 4 is pushed out by the air cylinder 6 to press the bottle 1. Projections 9-12
Since both are formed so as to be in contact with the upper body part and the lower body part of the bottle, the bottle receives the load only at these parts. Furthermore, since the pressing means 4 is supported by the horizontal shaft 8 so as to be swingable in its axial direction, equal loads are applied to the protrusions 11 and 12.
この結果は第４図に白丸で示す通りであつて、
ビン胴部のＢ、Ｃ、Ｄの各部分に生ずる最大引張
応力はほぼ等しくなる。これは変形を生じにくい
ビン口部及びビン底部に近い部分が等しい力で押
圧され、逆に変形しやすい胴中央部が押圧されな
いためであると考えられる。 This result is as shown by the white circle in Figure 4,
The maximum tensile stress occurring in each portion of the bottle body, B, C, and D, is approximately equal. This is thought to be because the parts near the bottle mouth and bottle bottom, which are less prone to deformation, are pressed with equal force, while the central part of the body, which is more likely to deform, is not pressed.

こととなるが、このときＢには81×0.3＝24.3

みであるから、これらの部分に強度が130Kg／cm2
に満たない欠陥部分があつたとしてもこれを検出
することができないのである。 Let us now assume that the guaranteed internal pressure strength of a glass bottle is 10Kg/cm 2
If this is the case, the body of the glass bottle needs to be strong enough to withstand the tensile stress generated on its outer surface when an internal pressure of 10 kg/cm 2 is applied. This value is approximately
Since it is known that the pressure is 130Kg/cm 2 , a pressing force of approximately 190Kg is generated in the air cylinder 6. As can be seen from Figure 4, for a pressing force of 1 kg, approximately
Since a tensile stress of 0.7 Kg/cm 2 is generated on the outer surface of the bottle, for a force of 190 Kg, a maximum tensile stress of about 133 Kg/cm 2 is generated in portions B to D of the glass bottle. Therefore, if there is a defect in the range B to D with a strength of less than 130 kg/cm 2 , the glass bottle will be destroyed by the apparatus of the present invention. On the other hand, in the conventional device shown in Fig. 3, in order to make the maximum tensile stress value of part D 130Kg/cm 2 , the pressing force must be set to 130/1.6 = 81Kg. is 81×0.3=24.3
Since only a stress of Kg/cm 2 and 97.2Kg/cm 2 is generated in C, the strength of these parts is 130Kg/cm 2
Even if there is a defective part that is less than 100%, it cannot be detected.

することが可能となる。 As explained above, the device of the present invention has the pressing means formed with a protrusion that comes in contact with the upper body part and the lower body part of the glass bottle, and also supports one side of the pressing means so as to be swingable in the axial direction of the glass bottle. This system presses the upper and lower parts of the glass bottle with equal force, making it possible to reliably detect defects in the glass bottle's body over a wider area, and to more fully evaluate the internal pressure strength of the glass bottle. It becomes possible to guarantee this.

ない。 In the above embodiment, a cylindrical body and a concave cylindrical surface were used as the pressing means, but the pressing means may also have a planar shape, and the cylinder or the like that generates the pressing force can be placed on either side. There is no problem with installing it. Furthermore, it is preferable that the protrusions 9 to 12 are provided on the pressing means on both sides as in the embodiment.
Even if it is provided only on one of the pressing means, substantially the same effect can be obtained. Furthermore, in the embodiment, the concave cylindrical face body is swingably supported, but it goes without saying that any pressing means may be swingably supported.
このように本発明は従来技術の欠点をよく解決
