Become.
本発明の一実施形態に係る強度検査装置１００は、支持ユニット、光学系ユニット及び荷重発生ユニットを有している。
支持ユニットは、図１に示すように、被検査物であるびんＢの底部を支持する底部支持台１１１と、上下に移動可能で被検査物であるびんＢの口部を底部方向に押圧可能な口部押圧部１１２とを有している。
本実施形態では、支持ユニットは２側面が開放された矩形のユニット本体１１３を有し、底部支持台１１１は、ユニット本体１１３の底部内面に配置され、口部押圧部１１２は、ユニット本体１１３の上部内面に上下動可能に配置されているが、連続的に搬送される被検査物の搬送ライン中に配置する場合には、例えば搬送タレットの各ポケットに底部支持台１１１及び口部押圧部１１２配置されてもよく、その場合、光学系ユニットは搬送タレットの各ポケットが通過できる位置に固定的に配置すればよい。
The strength inspection apparatus 100 according to an embodiment of the present invention includes a support unit, an optical system unit, and a load generation unit.
As shown in FIG. 1, the support unit is capable of moving up and down and pressing the mouth of the bottle B, which is the object to be inspected, in the bottom direction. And a mouth pressing portion 112.
In the present embodiment, the support unit has a rectangular unit main body 113 with two side surfaces open, the bottom support base 111 is disposed on the bottom inner surface of the unit main body 113, and the mouth pressing portion 112 is connected to the unit main body 113. Although it is arranged on the upper inner surface so as to be movable up and down, when it is arranged in the conveying line of the object to be continuously conveyed, for example, the bottom support 111 and the mouth pressing unit 112 are provided in each pocket of the conveying turret. In this case, the optical system unit may be fixedly disposed at a position where each pocket of the transport turret can pass.
光学系ユニットは、図１に示すように、底部支持台１１１に載置されたびんＢの一側方に、光源１２１、偏光子１２２及び１／４波長板１２３を有し、対向する側方に１／４波長板１２５、検光子１２４及び撮像部である撮像カメラ１２６を有している（図では簡略化のため配置のみ示している。）。
荷重発生ユニット１３０は、図１に示すように、口部押圧部１１２の上方に配置され、口部押圧部１１２によってびんＢの口部を底部方向に押圧して荷重を加えるように構成されている。
荷重発生ユニット１３０は、シリンダ径８０ｍｍのエアシリンダを使用しており、０．８ＭＰａの空気圧で動作させることで、びんＢの縦方向の荷重保証値の５０％である４ｋＮの荷重を発生させるように構成されている。
As shown in FIG. 1, the optical system unit has a light source 121, a polarizer 122, and a ¼ wavelength plate 123 on one side of the bottle B placed on the bottom support base 111, and opposite side surfaces. 4 includes a quarter-wave plate 125, an analyzer 124, and an imaging camera 126 that is an imaging unit (only the arrangement is shown in the figure for simplification).
As shown in FIG. 1, the load generating unit 130 is disposed above the mouth pressing portion 112 and is configured to apply a load by pressing the mouth of the bottle B toward the bottom by the mouth pressing portion 112. Yes.
The load generating unit 130 uses an air cylinder having a cylinder diameter of 80 mm, and is operated at an air pressure of 0.8 MPa so as to generate a load of 4 kN, which is 50% of the guaranteed load in the vertical direction of the bottle B. It is configured.
本実施形態では、偏光子１２２及び検光子１２４が直線偏光板で構成され、偏光子１２２の後に１／４波長板１２３を有していることから、びんＢを通過する光は円偏光に変換されたものとなり、検光子１２４の前に１／４波長板１２５を有していることから、びんＢを通過した光は、直線偏光に戻されて撮像カメラ１２６で撮像されることとなる。
このことで、傷や不純物の形状や方向性に関わらず、より確実に強度低下部を検出することができる。
また、本実施形態では、偏光子１２２と検光子１２４の偏光軸が９０°となるように配置されることで、びんＢに内部応力等による歪が存在しない場合にはびんＢをそのまま通過して、光源１２１の光は偏光子１２２と検光子１２４で遮断され、撮像カメラ１２６には届かないように構成されている。
In the present embodiment, the polarizer 122 and the analyzer 124 are configured by linearly polarizing plates, and have a quarter-wave plate 123 after the polarizer 122, so that light passing through the bottle B is converted into circularly polarized light. Since the quarter wavelength plate 125 is provided in front of the analyzer 124, the light that has passed through the bottle B is returned to linearly polarized light and imaged by the imaging camera 126.
This makes it possible to detect the reduced strength portion more reliably regardless of the shape and directionality of the scratches and impurities.
In the present embodiment, the polarizer 122 and the analyzer 124 are arranged so that the polarization axes are 90 °, so that the bottle B passes through the bottle B as it is when there is no distortion due to internal stress or the like. Thus, the light from the light source 121 is blocked by the polarizer 122 and the analyzer 124 and does not reach the imaging camera 126.
このことで、通常は光が遮断され、びんＢに荷重をかけた際に内部応力により旋光して明るくなり、傷や不純物が存在する場所に内部応力が集中して特に明るく検知されるため、強度低下部として確実に検出することができる。
なお、１／４波長板１２３及び１／４波長板１２５を省略して、直線偏光のままびんＢを通過させてもよく、偏光子１２２と検光子１２４の偏光軸を同一位相として、びんＢに内部応力等による歪が存在しない場合にはびんＢをそのまま通過して、光源１２１の光が遮断されることなく撮像カメラ１２６に届くようにしてもよい。
また、光学系ユニットを複数台使用したり、びんを回転、揺動等適宜動かすことにより、ガラスびんの全方位の非破壊強度検査を行ってもよい。
さらに、連続的に搬送される被検査物の搬送ライン中に配置する場合には、光学系ユニットよりも下流側に、不良品と判定されたびんＢを搬送経路外に排除する装置を配置してもよい。
Because of this, the light is normally blocked, and when a load is applied to the bottle B, the light is rotated by the internal stress and brightens, and the internal stress is concentrated in a place where scratches and impurities are present, so that it is detected particularly brightly. It can be reliably detected as a reduced strength part.
The quarter wavelength plate 123 and the quarter wavelength plate 125 may be omitted, and the bottle B may be allowed to pass through with linear polarization, and the polarization axes of the polarizer 122 and the analyzer 124 are set to the same phase, and the bottle B If there is no distortion due to internal stress or the like, the bottle B may be passed through as it is, and the light from the light source 121 may reach the imaging camera 126 without being blocked.
Further, non-destructive strength inspection in all directions of the glass bottle may be performed by using a plurality of optical system units or by appropriately moving the bottle such as rotating and swinging.
Furthermore, when arranging in the conveyance line of the inspection object to be continuously conveyed, an apparatus for removing bottle B determined as a defective product out of the conveyance path is arranged downstream of the optical system unit. May be.
以上のように構成された強度検査装置１００によるびんＢの検査について説明する。
びんＢに不純物や傷による強度低下部がない場合の、撮像カメラ１２６の画像を図２に示す。
びんＢの内部応力等による歪が存在しない場合、荷重発生ユニット１３０で荷重を加えない無負荷の状態では、偏光子１２２及び１／４波長板１２３を通過した光はびんＢによって偏光されることはなく、１／４波長板１２５及び検光子１２４によって遮断され、撮像カメラ１２６の画像は写真の最も左に示すように非常に暗く、ほぼ何も写っていない状態となる。
このびんＢに荷重を加えると、肩部及び底部付近及び肩部に内部応力が集中するため、荷重が大きくなるほど歪も大きくなり、歪の大きさに比例してその部分を通過する光の旋光量も大きなって１／４波長板１２５及び検光子１２４を通過する光量が増加し、撮像カメラ１２６の画像も荷重が大きくなるほど明るくなる。
The inspection of the bottle B by the strength inspection apparatus 100 configured as described above will be described.
FIG. 2 shows an image of the imaging camera 126 when the bottle B does not have a reduced strength portion due to impurities or scratches.
When there is no distortion due to the internal stress or the like of the bottle B, the light passing through the polarizer 122 and the quarter-wave plate 123 is polarized by the bottle B in an unloaded state where no load is applied by the load generating unit 130. The image is captured by the quarter-wave plate 125 and the analyzer 124, and the image of the imaging camera 126 is very dark as shown in the leftmost part of the photograph, and almost nothing is captured.
When a load is applied to the bottle B, the internal stress concentrates on the shoulder and bottom, and on the shoulder, so the strain increases as the load increases, and the optical rotation of light passing through that portion in proportion to the magnitude of the strain The amount of light that passes through the quarter-wave plate 125 and the analyzer 124 increases, and the image of the imaging camera 126 becomes brighter as the load increases.
びんＢの肩部の内面に傷による強度低下部が存在する場合の、撮像カメラ１２６の画像を図３に示す。
荷重発生ユニット１３０で荷重を加えない無負荷の状態では、傷の部分に内部応力等による歪は存在しないため、図３の左に示すように、他の部分と同様に暗いままであり、撮像カメラ１２６の画像にも全く映らない。
荷重発生ユニット１３０にシリンダ圧０．８ＭＰａ（びんＢの縦方向の荷重保証値の５０％である４ｋＮの荷重相当）を加えると、肩部のため全体に内部応力による歪みが発生して明るくなるが、傷の部分では内部応力の加わり方が異なるため異なる歪が発生し、図３の右に示すように、撮像カメラ１２６の画像で、傷の部分が周囲との明るさの違いで明確に形状が判別できる状態となる。
これを、公知の画像処理システム等で判断することで、びんＢの強度低下部として検出することができる。
FIG. 3 shows an image of the imaging camera 126 in the case where there is a reduced strength portion due to scratches on the inner surface of the shoulder portion of the bottle B.
In the unloaded state where no load is applied by the load generating unit 130, there is no distortion due to internal stress or the like in the scratched part, and therefore, as shown on the left in FIG. Neither appears in the camera 126 image.
When a cylinder pressure of 0.8 MPa (corresponding to a load of 4 kN which is 50% of the load guarantee value in the vertical direction of bottle B) is applied to the load generation unit 130, distortion due to internal stress is generated on the whole because of the shoulder, and it becomes brighter. However, since the internal stress is applied differently in the scratched part, different distortion occurs. As shown on the right side of FIG. 3, the scratched part is clearly shown in the image of the imaging camera 126 due to the difference in brightness from the surroundings. The shape can be discriminated.
By determining this with a known image processing system or the like, it can be detected as a reduced strength portion of bottle B.
びんＢの胴部に異物が存在している場合の、撮像カメラ１２６の画像を図４に示す。
荷重発生ユニット１３０で荷重を加えない無負荷の状態では、図４の左に示すように、僅かな歪は確認できるものの、使用に支障のない内部歪のばらつきか、強度低下部となりうる異物の存在かは判別ができない。
荷重発生ユニット１３０にシリンダ圧０．８ＭＰａ（びんＢの縦方向の荷重保証値の５０％である４ｋＮの荷重相当）を加えると、図４の右に示すように、異物の存在による歪み方向が変化したり、大きな歪となることが撮像カメラ１２６の画像で確認できる。
これを、公知の画像処理システム等で判断することで、びんＢの強度低下部として検出することができる。
FIG. 4 shows an image of the imaging camera 126 in the case where foreign matter is present in the bottle B body.
In the unloaded state in which no load is applied by the load generating unit 130, as shown on the left of FIG. 4, although slight distortion can be confirmed, there is a variation in internal distortion that does not hinder the use, or foreign matter that can become a reduced strength part. It cannot be determined whether it exists.
When a cylinder pressure of 0.8 MPa (corresponding to a load of 4 kN which is 50% of the guaranteed load value in the vertical direction of bottle B) is applied to the load generating unit 130, the strain direction due to the presence of foreign matter is changed as shown on the right side of FIG. It can be confirmed from the image of the imaging camera 126 that the image changes or becomes a large distortion.
By determining this with a known image processing system or the like, it can be detected as a reduced strength portion of bottle B.
