Description

ガラスびんの検査装置Glass bottle inspection equipment
　本発明は、ガラスびんの欠点を発光部と受光部を用いて検出するガラスびんの検査装置に関するものである。 The present invention relates to a glass bottle inspection device that detects a defect of a glass bottle using a light emitting part and a light receiving part.
　ガラスびんの口部や首部にはびりと呼ばれる欠点がガラスびんの製造工程で発生することがある。びりは、ひび割れのようなクラックであり、略鉛直方向（びんの軸方向）に延びる垂直びりと、略水平方向（びんの軸方向に直交する方向）に延びる水平びりと、がある。 A defect called chatter may occur in the glass bottle manufacturing process at the mouth and neck of the glass bottle. The chatter is a crack like a crack, and includes a vertical chatter extending in a substantially vertical direction (a bottle axial direction) and a horizontal chatter extending in a substantially horizontal direction (a direction orthogonal to the bottle axial direction).
　従来、このようなびりを検出するため、ガラスびんの特定部位を撮像し、その画像からびりを検出するガラスびんの検査装置が知られている（例えば、特許文献１）。検査装置は、ガラスびんに投光する照明と、撮像するカメラと、画像を処理してびりを検出する画像処理装置とを備える。 Conventionally, in order to detect such chatter, there is known a glass bottle inspection apparatus that images a specific part of a glass bottle and detects the chatter from the image (for example, Patent Document 1). The inspection device includes illumination that projects light onto a glass bottle, a camera that captures an image, and an image processing device that processes the image to detect chatter.
　びり等のガラスびんの欠点は、常に同じ部分に現れるわけではなく、また、常に同じ形状の凹部であるわけでもない。そのため、欠点の反射光や屈折光に対応するため、複数箇所に受光部が設けられている。 The drawbacks of glass bottles such as chatters do not always appear in the same part, and are not always concave parts of the same shape. Therefore, in order to cope with the reflected light and refracted light of the defect, light receiving portions are provided at a plurality of locations.
　また、複数個の投光器と複数個の受光器を備えるガラスびんの検査装置としては、複数の投光器を順次１個ずつ瞬時的に投光することが提案されている（例えば、特許文献２）。このようにすることで、複数個の投光機を用いても照射光が互いに干渉し合って検出率が落ちたり、小さな気泡まで過剰に光って検査精度が低下するという事態を解消している。 Further, as a glass bottle inspection apparatus including a plurality of projectors and a plurality of light receivers, it has been proposed to instantaneously project a plurality of projectors one by one in sequence (for example, Patent Document 2). By doing this, even if a plurality of projectors are used, the situation where the irradiation light interferes with each other and the detection rate decreases, or even small bubbles shine excessively and the inspection accuracy is reduced is eliminated. .

　１－１．検査装置の概要
　図１に示すように、検査装置１０は、搬入口１８と、搬送経路１２と、第１ユニット１１ａと、第２ユニット１１ｂと、搬出口１９と、を含む。 1-1. Outline of Inspection Device As shown in FIG. 1, the inspection device 10 includes a carry-in port 18, a conveyance path 12, a first unit 11 a, a second unit 11 b, and a carry-out port 19.
　まず、ガラスびん１は、検査装置１０の搬入口１８から搬送経路１２へ間欠的に搬入される。搬送経路１２には図示しない８個の支持台が設けられ、ガラスびん１を１本ずつ支持する。ガラスびん１は、支持台に支持されたまま各ステージへと搬送経路１２を間欠的に搬送される。 First, the glass bottle 1 is intermittently carried into the conveyance path 12 from the carry-in port 18 of the inspection apparatus 10. The transport path 12 is provided with eight support tables (not shown), and supports the glass bottles 1 one by one. The glass bottle 1 is intermittently transported along the transport path 12 to each stage while being supported by the support base.
　搬送経路１２は、搬送中心軸１５を中心とする円周上に形成される。ガラスびん１は、搬送経路１２を図１の右回りに搬送される。自転位置１４は、ガラスびん１の搬送経路１２の途中に設けられており、自転位置１４に搬送されてくるガラスびん１を順次検査することができる。搬送経路１２の途中に自転位置１４を設けることにより、ガラスびん１の搬送途中で効率的に順次検査を行うことができる。搬送経路１２には、第２ユニット１１ｂの自転位置１４とは異なる位置（ガラスびん１の搬送方向の上流側）に、第１ユニット１１ａが設けられた別の自転位置１４が設けられており、この別の自転位置１４において、第２ユニット１１ｂの自転位置１４における検査項目とは異なる検査をすることができる。ガラスびん１の搬送途中で異なる検査項目を効率的に行うことができる。第１ユニット１１ａ及び第２ユニット１１ｂの自転位置１４に停止したガラスびん１は、支持台の回転によってガラスびん１の中心軸５（図３）の周りを自転する。搬送経路１２は円周に限らず、他の形状、例えば直線上に形成されてもよい。 The conveyance path 12 is formed on a circumference around the conveyance center axis 15. The glass bottle 1 is conveyed in the clockwise direction in FIG. The rotation position 14 is provided in the middle of the conveyance path 12 of the glass bottle 1, and the glass bottle 1 conveyed to the rotation position 14 can be inspected sequentially. By providing the rotation position 14 in the middle of the conveyance path 12, it is possible to sequentially inspect the glass bottle 1 in the middle of the conveyance efficiently. In the conveyance path 12, another rotation position 14 provided with the first unit 11a is provided at a position different from the rotation position 14 of the second unit 11b (upstream side in the conveyance direction of the glass bottle 1). At this different rotation position 14, an inspection different from the inspection item at the rotation position 14 of the second unit 11b can be performed. Different inspection items can be efficiently performed during the transportation of the glass bottle 1. The glass bottle 1 stopped at the rotation position 14 of the first unit 11a and the second unit 11b rotates around the central axis 5 (FIG. 3) of the glass bottle 1 by the rotation of the support base. The conveyance path 12 is not limited to the circumference, but may be formed in another shape, for example, a straight line.
　搬送経路１２の各ステージには、さらに他の検査ユニット等を設けることができる。各ステージの検査工程を経たガラスびん１は、搬出口１９から検査装置１０の外へ送り出され、良品の場合は次のラインへと移動する。 Further inspection units or the like can be provided in each stage of the transport path 12. The glass bottle 1 that has undergone the inspection process of each stage is sent out of the inspection apparatus 10 from the carry-out port 19 and moves to the next line in the case of a non-defective product.
　第１ユニット１１ａは水平びりを検出する検査ユニットであり、第２ユニット１１ｂは垂直びりを検出する検査ユニットである。２つの検査ユニットにより異なる検査項目（例えば異なる種類の欠点）を検査することができる。搬送経路１２に設けられる検査ユニットは３つ以上あってもよい。 The first unit 11a is an inspection unit that detects horizontal vibration, and the second unit 11b is an inspection unit that detects vertical vibration. Different inspection items (for example, different types of defects) can be inspected by the two inspection units. There may be three or more inspection units provided in the transport path 12.
　びりは、ガラスびん１の製造に際して、その口部２に生じるひび割れのような欠点である。びりが検出されたガラスびん１は、不良品として廃棄される。ガラスびん１の口部２に生じるびりの種類は多数あるが、その内、第１ユニット１１ａではガラスびん１の略水平方向に延びる水平びりを検出し、第２ユニット１１ｂではガラスびん１の略鉛直方向に延びる垂直びりを検出する。ここではびりを検出する装置について説明するが、びり以外の欠点、例えば気泡等を検出してもよい。 The chatter is a defect such as a crack generated in the mouth portion 2 when the glass bottle 1 is manufactured. The glass bottle 1 in which the vibration is detected is discarded as a defective product. There are many kinds of chatters generated at the mouth portion 2 of the glass bottle 1. Among them, the first unit 11 a detects a horizontal chatch extending substantially in the horizontal direction of the glass bottle 1, and the second unit 11 b is an abbreviation of the glass bottle 1. Detects vertical vibration extending in the vertical direction. Although an apparatus for detecting chatter will be described here, defects other than chatter, such as bubbles, may be detected.
　口部２には、通常蓋などを嵌めるためのねじ等の構成があるため狭い範囲に多くの起伏があり、びりが発生し易い反面びりを検出するのが難しい。光学系の検査ユニットには、多種類のびりを高精度に検出することが求められる。そのため、びりの発生場所や形状に応じて複数の受光部が設けられる。 The mouth 2 has a structure such as a screw for fitting a lid or the like, so there are many undulations in a narrow range, and it is difficult to detect chatter on the other hand. An optical inspection unit is required to detect various types of chatter with high accuracy. Therefore, a plurality of light receiving units are provided according to the occurrence location and shape of chatter.
　検査装置１０は、第１ユニット１１ａ及び第２ユニット１１ｂに電気的に接続された制御部６２を含む。制御部６２は、判定部６３と、テンプレート作成部６４と、テンプレート記憶部６５と、画像処理部６６と、を含む。画像処理部６６は、第１ユニット１１ａ及び第２ユニット１１ｂで撮像されたデータを所定の明るさの画像データに変換する。テンプレート作成部６４は、第１ユニット１１ａ及び第２ユニット１１ｂで撮像された良品のガラスびん１のみのデータに基づいてテンプレートを作成する。作成されたテンプレートは、テンプレート記憶部６５に記憶される。判定部６３は、画像処理部６６で変換された画像データと、テンプレート記憶部６５に記憶されたテンプレートとの明るさを比較して、あらかじめ設定したしきい値を超えた場合にびり有りと判定する。また、制御部６２は、自転位置１４毎に設けられた回転検出部６８にも電気的に接続され、ガラスびん１の自転による回転角度の情報が入力される。 The inspection apparatus 10 includes a control unit 62 electrically connected to the first unit 11a and the second unit 11b. The control unit 62 includes a determination unit 63, a template creation unit 64, a template storage unit 65, and an image processing unit 66. The image processing unit 66 converts data captured by the first unit 11a and the second unit 11b into image data having a predetermined brightness. The template creation unit 64 creates a template based on data of only the non-defective glass bottle 1 imaged by the first unit 11a and the second unit 11b. The created template is stored in the template storage unit 65. The determination unit 63 compares the brightness of the image data converted by the image processing unit 66 and the template stored in the template storage unit 65, and determines that there is a chatter when a preset threshold value is exceeded. To do. The control unit 62 is also electrically connected to a rotation detection unit 68 provided for each rotation position 14, and information on the rotation angle due to the rotation of the glass bottle 1 is input.
　以下の説明では、主に第２ユニット１１ｂについて説明するが、同様の構成を第１ユニット１１ａに適用してもよく、また、図示しない他の検査ユニットに適用してもよい。 In the following description, the second unit 11b will be mainly described. However, the same configuration may be applied to the first unit 11a, or may be applied to another inspection unit (not shown).
　１－２．第２ユニット
　図２及び図３に示すように、第２ユニット１１ｂは、ガラスびん１の口部２に向けて可視光を照射する第１発光部２０と、口部２に向けて赤外光を照射する第２発光部３０（図３では省略）と、口部２からの可視光の反射光または屈折光を検出する第１受光部４０と、口部２からの赤外光の反射光または屈折光を検出する第２受光部５０（図３では省略）と、を含む。 1-2. 2nd unit As shown in FIG.2 and FIG.3, the 2nd unit 11b is the 1st light emission part 20 which irradiates visible light toward the opening part 2 of the glass bottle 1, and infrared light toward the opening part 2. The second light emitting unit 30 (not shown in FIG. 3) that irradiates the light, the first light receiving unit 40 that detects the reflected or refracted light of the visible light from the mouth 2, and the reflected light of the infrared light from the mouth 2. Or the 2nd light-receiving part 50 (it omits in FIG. 3) which detects refracted light.
　図２に示すように、第１発光部２０、第２発光部３０、第１受光部４０及び第２受光部５０は、ガラスびん１の搬送経路１２に設けられたガラスびん１を自転させる自転位置１４において、ガラスびん１の周囲に配置される。第１発光部２０、第２発光部３０、第１受光部４０及び第２受光部５０は、びり等の発生場所及び形状に適応するように予め設定された所定の位置に配置される。赤外光と可視光とを用いることにより、複数の発光部（２０，３０）を用いても、受光部（４０，５０）で受光される光の干渉を防ぎながらガラスびん１の口部２に発生するびり等を検出することができる。 As shown in FIG. 2, the first light emitting unit 20, the second light emitting unit 30, the first light receiving unit 40, and the second light receiving unit 50 rotate to rotate the glass bottle 1 provided in the conveyance path 12 of the glass bottle 1. At position 14 it is placed around the glass bottle 1. The 1st light emission part 20, the 2nd light emission part 30, the 1st light-receiving part 40, and the 2nd light-receiving part 50 are arrange | positioned in the predetermined position preset so that it may adapt to generation | occurrence | production locations and shapes, such as chatter. By using infrared light and visible light, the mouth portion 2 of the glass bottle 1 while preventing interference of light received by the light receiving portions (40, 50) even if a plurality of light emitting portions (20, 30) are used. It is possible to detect chatter and the like generated in
　第１受光部４０は、第１発光部２０の可視光を受光する２以上の受光部４０～４３の１つである。第２受光部５０は、第２発光部３０の赤外光を受光する２以上の受光部５０～５３の１つである。このように、可視光を受光する複数の受光部４０～４３と赤外光を受光する複数の受光部５０～５３とを備えることで、びり等の検出精度を向上させることができる。以下の説明では、可視光を受光する受光部４０～４３の代表例として第１受光部４０について説明し、赤外光を受光する受光部５０～５３の代表例として第２受光部５０について説明する。 The first light receiving unit 40 is one of two or more light receiving units 40 to 43 that receive the visible light of the first light emitting unit 20. The second light receiving unit 50 is one of two or more light receiving units 50 to 53 that receive the infrared light of the second light emitting unit 30. As described above, by including the plurality of light receiving units 40 to 43 that receive visible light and the plurality of light receiving units 50 to 53 that receive infrared light, it is possible to improve the detection accuracy of chatter and the like. In the following description, the first light receiving unit 40 will be described as a representative example of the light receiving units 40 to 43 that receive visible light, and the second light receiving unit 50 will be described as a representative example of the light receiving units 50 to 53 that receive infrared light. To do.
　第１発光部２０及び第２発光部３０は、ＬＥＤ（発光ダイオード）を用いた拡散照明である。拡散照明を用いることで大きい立体角を得ることができ、多種多様のびりからの反射光または屈折光が得られやすい。 The 1st light emission part 20 and the 2nd light emission part 30 are diffused illumination using LED (light emitting diode). A large solid angle can be obtained by using diffuse illumination, and reflected light or refracted light from various kinds of chatters can be easily obtained.
　第１発光部２０は、可視光を発光する。第１発光部２０は、検査対象となるガラスびん１の色に応じた透過率の高い波長の可視光を照射するように設定することが好ましい。ガラスびん１は自身の色によって光の透過率が異なるため、第１受光部４０における検出精度に影響がある。そのため、第１発光部２０の可視光をガラスびん１の色に応じた透過率の高い波長とすることで、ガラスびん１の色によって検出精度に影響が出るのを防ぐことができる。 The first light emitting unit 20 emits visible light. It is preferable to set the 1st light emission part 20 so that the visible light of the wavelength with the high transmittance | permeability according to the color of the glass bottle 1 used as a test object may be irradiated. Since the glass bottle 1 has different light transmittance depending on its own color, the detection accuracy in the first light receiving unit 40 is affected. Therefore, it is possible to prevent the detection accuracy from being affected by the color of the glass bottle 1 by setting the visible light of the first light emitting unit 20 to a wavelength having a high transmittance according to the color of the glass bottle 1.
　透過率の高い波長についてさらに説明する。第１発光部２０のＬＥＤとして緑色ＬＥＤ照明と赤色ＬＥＤ照明とを準備した場合、ガラスびん１の色が例えば緑色系や青色系の場合には赤色の波長領域よりも緑色の波長領域の方がガラスびん１の光の透過率が高いため、緑色ＬＥＤ照明を採用する。また、ガラスびん１の色が例えば茶色系や黒系の場合には、緑色の波長領域よりも赤色の波長領域の方がガラスびん１の光の透過率が高いので、赤色ＬＥＤ照明を採用する。このように、第１発光部２０の可視光をガラスびん１の色に応じた波長に設定することにより、第１受光部４０において十分に光を認識することができるため、ガラスびん１の色に影響されずにびり等を高い精度で検出することができる。また、例えば、ガラスびん１の色が透明の場合には、緑色ＬＥＤを採用することができるが、赤色の波長も緑色の波長と同程度に透過するため、赤色ＬＥＤを採用してもよい。このように、第１発光部２０の可視光は、ガラスびん１に対して透過率の高い波長の光が選択される。 The wavelength with high transmittance will be further described. When green LED illumination and red LED illumination are prepared as LEDs of the first light emitting unit 20, when the color of the glass bottle 1 is, for example, green or blue, the green wavelength region is more than the red wavelength region. Since the light transmittance of the glass bottle 1 is high, green LED illumination is adopted. Further, when the color of the glass bottle 1 is, for example, brown or black, red LED illumination is employed because the light transmittance of the glass bottle 1 is higher in the red wavelength region than in the green wavelength region. . Thus, by setting the visible light of the first light emitting unit 20 to a wavelength corresponding to the color of the glass bottle 1, the first light receiving unit 40 can sufficiently recognize the light, so that the color of the glass bottle 1 It is possible to detect chatter and the like with high accuracy without being affected by the above. For example, when the color of the glass bottle 1 is transparent, a green LED can be used. However, since the red wavelength is transmitted to the same extent as the green wavelength, a red LED may be used. As described above, as the visible light of the first light emitting unit 20, light having a wavelength that is higher in transmittance than the glass bottle 1 is selected.
　第１発光部２０は、複数色を選択して発光できるように複数色のＬＥＤを備えていてもよいし、色の異なるガラスびん１の検査に変更された場合に異なる色のＬＥＤに取り換えてもよい。 The first light emitting unit 20 may be provided with a plurality of color LEDs so that a plurality of colors can be selected and emitted, and when the first light emitting unit 20 is changed to the inspection of the glass bottle 1 having a different color, the first light emitting unit 20 is replaced with a different color LED. Also good.
　第２発光部３０は、赤外光を発光する。赤外光は、ガラスびんの色による影響が少ないため好ましい。 The second light emitting unit 30 emits infrared light. Infrared light is preferable because it is less affected by the color of the glass bottle.
　第１受光部４０及び第２受光部５０は、例えば、高速エリアセンサカメラを用いることができる。第１受光部４０及び第２受光部５０は、可視光及び赤外光の輝度を検出することができる他の公知の手段を用いてもよい。 For the first light receiving unit 40 and the second light receiving unit 50, for example, a high-speed area sensor camera can be used. The first light receiving unit 40 and the second light receiving unit 50 may use other known means capable of detecting the luminance of visible light and infrared light.
　第１受光部４０は、第１発光部２０の可視光を透過し、第２発光部３０の赤外光を透過しないバンドパスフィルター４０ａを備える。バンドパスフィルター４０ａは、例えば第１発光部２０の可視光が緑色である場合には、緑色の波長域を選択的に透過させる緑バンドパスフィルターを採用することができる。バンドパスフィルター４０ａによって緑色以外の特に赤外光を透過しない（例えば吸収する）ことで、外乱による誤検出を防止することができる。 The first light receiving unit 40 includes a band-pass filter 40 a that transmits the visible light of the first light emitting unit 20 and does not transmit the infrared light of the second light emitting unit 30. As the band pass filter 40a, for example, when the visible light of the first light emitting unit 20 is green, a green band pass filter that selectively transmits the green wavelength band can be employed. The band-pass filter 40a does not transmit (for example, absorbs) infrared light other than green light, so that erroneous detection due to disturbance can be prevented.
　第２受光部５０は、第２発光部３０の赤外光を透過し、第１発光部２０の可視光を透過しないバンドパスフィルター５０ａを備えることができる。バンドパスフィルター５０ａは、第２発光部３０の赤外光の波長域を選択的に透過させる。バンドパスフィルター５０ａによって赤外光以外の可視光を透過しない（例えば吸収する）ことで、外乱による誤検出を防止することができる。 The second light receiving unit 50 may include a band pass filter 50a that transmits the infrared light of the second light emitting unit 30 and does not transmit the visible light of the first light emitting unit 20. The band pass filter 50 a selectively transmits the infrared light wavelength region of the second light emitting unit 30. By not transmitting (for example, absorbing) visible light other than infrared light by the bandpass filter 50a, erroneous detection due to disturbance can be prevented.
　バンドパスフィルター４０ａ，５０ａによって受光させたい光を選別して第１受光部４０及び第２受光部５０に所定の波長域の光だけを受光することができる。バンドパスフィルター４０ａ，５０ａは、特定の波長帯のみを透過する光学フィルターである。バンドパスフィルター４０ａ，５０ａとしては、例えば、誘電体多層膜フィルターやフィルタガラス等を用いることができる。 The light to be received by the bandpass filters 40a and 50a can be selected and only the light in a predetermined wavelength range can be received by the first light receiving unit 40 and the second light receiving unit 50. The bandpass filters 40a and 50a are optical filters that transmit only a specific wavelength band. As the band- pass filters 40a and 50a, for example, a dielectric multilayer filter or a filter glass can be used.
　図２において第１受光部４０と第２受光部５０との間を通り、かつ、ガラスびん１の自転の中心軸５を含む仮想面７（一点鎖線で示す）がある。仮想面７は、搬送中心軸１５と自転の中心軸５を通る仮想的に設定された面であってもよい。第１発光部２０は、仮想面７に対して、第２発光部３０と面対称の位置に配置され、第１受光部４０は、仮想面７に対して、第２受光部５０と面対称の位置に配置される。可視光を受光する受光部４１～４３も同様に仮想面７に対して赤外光を受光する受光部５１～５３と面対称の位置に配置される。第１、第２発光部２０，３０及び受光部４０～４３，５０～５３が面対称に配置されることで口部２におけるガラスびん１の中心軸５に対し同じ高さ位置に発生する形状の違うびり等からの反射または屈折する光を他の光の外乱光を防ぎつつ、検出できるため、びり等の検出精度を向上させることができる。 In FIG. 2, there is a virtual plane 7 (indicated by a one-dot chain line) that passes between the first light receiving unit 40 and the second light receiving unit 50 and includes the central axis 5 of rotation of the glass bottle 1. The virtual surface 7 may be a virtually set surface that passes through the conveyance center axis 15 and the rotation center axis 5. The first light emitting unit 20 is disposed in a plane symmetric with the second light emitting unit 30 with respect to the virtual plane 7, and the first light receiving unit 40 is plane symmetric with the second light receiving unit 50 with respect to the virtual plane 7. It is arranged at the position. Similarly, the light receiving units 41 to 43 that receive visible light are arranged at positions symmetrical to the light receiving units 51 to 53 that receive infrared light with respect to the virtual plane 7. The first and second light emitting units 20 and 30 and the light receiving units 40 to 43 and 50 to 53 are arranged in plane symmetry so that the shape generated at the same height position with respect to the central axis 5 of the glass bottle 1 in the mouth 2. Since the light reflected or refracted from different chatters or the like can be detected while preventing disturbance light of other light, the detection accuracy of the chatter or the like can be improved.
　図３は、仮想面７の搬送方向の上流側に配置された第１発光部２０及び受光部４０～４３の上下の配置を示している。図示は省略するが、仮想面７の搬送方向の下流側も第２発光部３０及び受光部５０～５３が同様の配置となる。 FIG. 3 shows the upper and lower arrangements of the first light emitting unit 20 and the light receiving units 40 to 43 arranged on the upstream side in the transport direction of the virtual plane 7. Although not shown, the second light emitting unit 30 and the light receiving units 50 to 53 are similarly arranged on the downstream side in the transport direction of the virtual plane 7.
　図４は、ガラスびん１の口部２における各受光部４０～４３，５０～５３の撮像領域を破線で示している。撮像領域が検査対象領域である。口部２とは、天面２ｂと、ねじ部（ねじは省略した）が形成される口部２の側面２ａと、下方の首部３と、を含む。首部３は、環状に突出するスカート部３ａと、スカート部３ａの直下の部分を含む。 FIG. 4 shows the imaging areas of the light receiving portions 40 to 43 and 50 to 53 in the mouth portion 2 of the glass bottle 1 by broken lines. The imaging area is the inspection target area. The mouth portion 2 includes a top surface 2b, a side surface 2a of the mouth portion 2 where a screw portion (screw is omitted), and a lower neck portion 3 are formed. The neck portion 3 includes a skirt portion 3a protruding in an annular shape and a portion directly below the skirt portion 3a.
　図４に示すように、第１受光部４０及び第２受光部５０は天面２ｂを含む口部２の上部領域が撮像領域であり、受光部４１，５１は口部２の側面２ａの内側面を含む領域が撮像領域であり、受光部４２，５２，４３，５３はスカート部３ａの上部領域及び下部領域（スカート部３ａの直下を含む）が撮像領域である。 As shown in FIG. 4, in the first light receiving unit 40 and the second light receiving unit 50, the upper region of the mouth part 2 including the top surface 2 b is an imaging region, and the light receiving parts 41 and 51 are inside the side surface 2 a of the mouth part 2. An area including the side surface is an imaging area, and the light receiving parts 42, 52, 43, and 53 are an upper area and a lower area (including immediately below the skirt part 3a) of the skirt part 3a.
　各受光部４０～４３，５０～５３の撮像領域は重複している部分がある。各受光部４０～４３，５０～５３の鉛直方向の高さや水平方向の位置が異なるため、重複した範囲にあるびりから反射または屈折した光を受光する確率が高くなる。各受光部４０～４３，５０～５３の撮像領域は、ガラスびん１の形状が替わってもびりが発生し易い場所を含んでいる。 The imaging areas of the light receiving units 40 to 43 and 50 to 53 have overlapping portions. Since the vertical heights and horizontal positions of the light receiving units 40 to 43 and 50 to 53 are different, the probability of receiving light reflected or refracted from chatter in the overlapping range is increased. The imaging regions of the light receiving units 40 to 43 and 50 to 53 include places where chatter is likely to occur even if the shape of the glass bottle 1 is changed.
　図５に示すように、水平びりを検出するための第１ユニット１１ａは、第２ユニット１１ｂと同様に発光部２００と受光部４００とを含む。発光部２００は、自転位置１４のガラスびん１に対して搬送中心軸１５側に設けられ、ガラスびん１の色に合わせて適宜選択する透過率の高い可視光のＬＥＤを含む。可視光であれば検査者が発光状態を視認しやすいからである。受光部４００は、発光部２００に対しガラスびん１を挟んで搬送経路１２の外側に複数（例えば７つ）配置され、ガラスびん１を透過してびり等の形状により異なる角度に屈折する光を受光する。受光部４００は、それぞれバンドパスフィルターを有し、発光部２００から出射された可視光の反射光または透過光を選択的に効率よく受光することができる。受光部４００は、バンドパスフィルターにより、例えば他の検査機からの光による外乱を防ぐことができる。 As shown in FIG. 5, the first unit 11a for detecting horizontal vibration includes a light emitting unit 200 and a light receiving unit 400 in the same manner as the second unit 11b. The light emitting unit 200 is provided on the side of the transport center axis 15 with respect to the glass bottle 1 at the rotation position 14, and includes a visible light LED with high transmittance that is appropriately selected according to the color of the glass bottle 1. This is because visible light makes it easy for an inspector to visually recognize the light emission state. A plurality of (for example, seven) light receiving units 400 are arranged outside the transport path 12 with the glass bottle 1 interposed therebetween with respect to the light emitting unit 200, and transmit light that refracts at different angles depending on the shape of the chatter and the like through the glass bottle 1. Receive light. Each of the light receiving units 400 includes a bandpass filter, and can selectively and efficiently receive reflected or transmitted light of visible light emitted from the light emitting unit 200. The light receiving unit 400 can prevent disturbance due to light from other inspection machines, for example, by a bandpass filter.
　２．変形例
　図６を用いて変形例の検査装置１０ａの第２ユニット１１ｃについて説明する。図６は、変形例の第２ユニット１１ｃの側面図である。第２ユニット１１ｃは、第１受光部４０及び第２受光部５０以外の第１、第２発光部２０，３０及び受光部４１～４３，５１～５３が図１～図３の検査装置１０と同様に配置される。図６は図３と同じ状態を示しているが、図６では第１受光部４０以外の受光部４１～４３を省略して示している。また、第２受光部５０は仮想面７（図２）に対して第１受光部４０と面対称の位置にある。なお、図１～図３と同じ構成については同じ符号を付して重複する説明を省略する。 2. Modification The second unit 11c of the inspection apparatus 10a according to a modification will be described with reference to FIG. FIG. 6 is a side view of a modified second unit 11c. In the second unit 11c, the first and second light emitting units 20, 30 and the light receiving units 41 to 43, 51 to 53 other than the first light receiving unit 40 and the second light receiving unit 50 are the same as the inspection apparatus 10 in FIGS. Arranged similarly. FIG. 6 shows the same state as FIG. 3, but in FIG. 6, the light receiving parts 41 to 43 other than the first light receiving part 40 are omitted. In addition, the second light receiving unit 50 is positioned symmetrically with the first light receiving unit 40 with respect to the virtual plane 7 (FIG. 2). Note that the same components as those in FIGS. 1 to 3 are denoted by the same reference numerals, and redundant description is omitted.
　搬送経路１２は、搬送中心軸１５を中心とする円周１６（図１）上に形成され、第１受光部４０（及び第２受光部５０）は、自転の中心軸５よりも搬送中心軸１５側に配置され、口部２からの反射光または屈折光をミラー６０で上方へ反射させて受光する。 The transport path 12 is formed on a circumference 16 (FIG. 1) centered on the transport center axis 15, and the first light receiving unit 40 (and the second light receiving unit 50) is more transported than the center axis 5 of the rotation. It is arranged on the 15 side, and the reflected light or refracted light from the mouth portion 2 is reflected upward by the mirror 60 and received.
　搬送中心軸１５の周囲には配線や配管等が集中しているため、第１受光部４０（及び第２受光部５０）は他の部品と干渉しやすい搬送中心軸１５側にミラー６０を用いることで第１受光部４０（及び第２受光部５０）の設置スペースを省くことができる。 Since wiring, piping, and the like are concentrated around the transport center axis 15, the first light receiving unit 40 (and the second light receiving unit 50) uses a mirror 60 on the side of the transport center axis 15 that easily interferes with other components. Thereby, the installation space of the 1st light-receiving part 40 (and 2nd light-receiving part 50) can be omitted.
　図６では、第１発光部２０の可視光が口部２の天面２ｂで屈折して口部２の内側の面からミラー６０に達し、ミラー６０で反射した光を第１受光部４０が受光している。第１受光部４０は例えば鉛直方向に延びるように配置されることで、搬送中心軸１５付近における設置スペースを省略できる。 In FIG. 6, the visible light of the first light emitting unit 20 is refracted by the top surface 2 b of the mouth 2, reaches the mirror 60 from the inner surface of the mouth 2, and the first light receiving unit 40 reflects the light reflected by the mirror 60. It is receiving light. The first light receiving unit 40 is disposed so as to extend in the vertical direction, for example, so that an installation space in the vicinity of the transport center axis 15 can be omitted.
　３．位置決め部
　図７及び図８を用いて検査装置１０の位置決め部７６について説明する。図７及び図８は位置決め方法を説明する第２ユニット１１ｂの側面図である。図７及び図８では、第１受光部４０以外の第２発光部３０及び受光部４１～４３，５０～５３を省略して示しているが、第１発光部２０，第２発光部３０及び受光部４１～４３，５０～５３も第１受光部４０と同様に取付部７０に所定位置で固定されている。また、第１ユニット１１ａも第２ユニット１１ｂと同様の位置決めに関する構成を有する。なお、図１～図３と同じ構成については同じ符号を付して重複する説明を省略する。 3. Positioning unit The positioning unit 76 of the inspection apparatus 10 will be described with reference to FIGS. 7 and 8. 7 and 8 are side views of the second unit 11b for explaining the positioning method. 7 and 8, the second light emitting unit 30 and the light receiving units 41 to 43, 50 to 53 other than the first light receiving unit 40 are omitted, but the first light emitting unit 20, the second light emitting unit 30, and Similarly to the first light receiving unit 40, the light receiving units 41 to 43 and 50 to 53 are fixed to the mounting unit 70 at predetermined positions. In addition, the first unit 11a has a configuration related to positioning similar to that of the second unit 11b. Note that the same components as those in FIGS. 1 to 3 are denoted by the same reference numerals, and redundant description is omitted.
　第２ユニット１１ｂは、図１～図３を用いて説明したように、搬送経路１２に設けられた自転位置１４で、第１、第２発光部２０，３０の光を受光部４０～４３，５０～５３で受光してガラスびん１を検査する。 As described with reference to FIGS. 1 to 3, the second unit 11 b receives the light from the first and second light emitting units 20 and 30 at the rotation position 14 provided in the transport path 12. The glass bottle 1 is inspected by receiving light at 50-53.
　図７に示すように、第２ユニット１１ｂは、第１受光部４０等が固定された取付部７０と、取付部７０を自転位置１４に対して進退させる第１移動機構７２と、取付部７０を昇降させる第２移動機構７４と、取付部７０の所定位置に取り付けられた位置決め部７６と、を含む。 As shown in FIG. 7, the second unit 11 b includes an attachment portion 70 to which the first light receiving portion 40 and the like are fixed, a first moving mechanism 72 that moves the attachment portion 70 forward and backward with respect to the rotation position 14, and the attachment portion 70. A second moving mechanism 74 that moves up and down, and a positioning portion 76 attached to a predetermined position of the attachment portion 70.
　自転位置１４に配置したガラスびん１に対し、第１移動機構７２及び第２移動機構７４によって、位置決め部７６がガラスびん１の口部２の側面２ａ及び天面２ｂに接触するまで取付部７０を移動させることで第１受光部４０を所定の位置に位置決め可能である。ガラスびん１の製造工場では、金型を交換することによって別の形状のガラスびん１を生産することがある。異なる形状のガラスびん１を検査することになっても、位置決め部７６によってガラスびん１の所定位置に第１受光部４０（第１、第２発光部２０，３０及び他の受光部４１～４３，５０～５３も同様）を容易かつ正確に位置決めすることができる。ガラスびん１の異なる形状としては、例えば、ねじ口や王冠口など口部２の形状、口径、ガラスびん１の高さが異なる場合がある。 With respect to the glass bottle 1 arranged at the rotation position 14, the first moving mechanism 72 and the second moving mechanism 74 allow the positioning portion 76 to contact the side surface 2 a and the top surface 2 b of the mouth portion 2 of the glass bottle 1. The first light receiving unit 40 can be positioned at a predetermined position by moving the. In the manufacturing factory of the glass bottle 1, another shape of the glass bottle 1 may be produced by exchanging the mold. Even when the glass bottle 1 having a different shape is to be inspected, the first light receiving unit 40 (the first and second light emitting units 20 and 30 and the other light receiving units 41 to 43 are placed at predetermined positions on the glass bottle 1 by the positioning unit 76. , 50 to 53) can be positioned easily and accurately. As the different shapes of the glass bottle 1, for example, the shape of the mouth portion 2, such as a screw mouth and a crown mouth, the diameter, and the height of the glass bottle 1 may be different.
　第１、第２発光部２０，３０及び受光部４０～４３，５０～５３の取付位置及び取付角度は、基本的にどのようなガラスびん１に対してもそのまま使用できる。発明者等のこれまでの経験及び実験により、びり等の発生場所に最も適した取付位置及び取付角度に設定されているからである。例えば、形状の異なるガラスびん１であってびりを有するサンプルについて検査装置１０を用いて検査したところ、９０％以上のサンプルについてびり有りと判定することができた。 The mounting positions and mounting angles of the first and second light emitting units 20 and 30 and the light receiving units 40 to 43 and 50 to 53 can be basically used as they are for any glass bottle 1. This is because the mounting position and the mounting angle that are most suitable for the occurrence location of the chatter and the like are set by the inventors' previous experience and experiments. For example, when the glass bottles 1 having different shapes and having chatter were inspected using the inspection apparatus 10, it was possible to determine that 90% or more of the samples had chatter.
　第１移動機構７２は、昇降板７１上に配置され、一方の先端に取付部７０が固定された２本のロッド７３（手前側の１本のみを図示している）と、ロッド７３の他方の先端に固定された手動ボールねじ機構とを含む。昇降板７１は搬送経路１２の搬送中心軸１５と反対側に配置される。手動ボールねじ機構のハンドルを回すことで昇降板７１にガイドされたロッド７３が取付部７０と共に搬送中心軸１５に対して前進または後退する。 The first moving mechanism 72 is disposed on the elevating plate 71 and has two rods 73 (only one on the near side is shown) with a mounting portion 70 fixed to one end, and the other of the rods 73. And a manual ball screw mechanism fixed to the tip of the head. The elevating plate 71 is disposed on the opposite side of the transport path 12 from the transport center axis 15. By rotating the handle of the manual ball screw mechanism, the rod 73 guided by the elevating plate 71 moves forward or backward with respect to the transport center shaft 15 together with the mounting portion 70.
　第１移動機構７２によって位置決め部７６を移動させると、位置決め部７６は自転位置１４におけるガラスびん１の中心軸５を通るように移動する。例えば、図２で示した仮想面７に沿って位置決め部７６が移動する。 When the positioning unit 76 is moved by the first moving mechanism 72, the positioning unit 76 moves so as to pass through the central axis 5 of the glass bottle 1 at the rotation position 14. For example, the positioning unit 76 moves along the virtual plane 7 shown in FIG.
　第２移動機構７４は、昇降板７１上に配置された手動ボールねじ機構と、一方の先端が固定台１３に固定され、他方の先端側が昇降板７１にガイドされたロッド７５とを含む。手動ボールねじ機構のハンドルを回すことで固定台１３に対し昇降板７１が昇降移動する。したがって、第２移動機構７４によって第１移動機構７２及び取付部７０の全体が昇降移動する。 The second moving mechanism 74 includes a manual ball screw mechanism disposed on the lifting plate 71 and a rod 75 having one tip fixed to the fixing base 13 and the other tip side guided by the lifting plate 71. The lift plate 71 moves up and down with respect to the fixed base 13 by turning the handle of the manual ball screw mechanism. Accordingly, the second moving mechanism 74 moves the first moving mechanism 72 and the mounting portion 70 up and down.
　第２移動機構７４によって位置決め部７６を移動させると、位置決め部７６は自転位置１４におけるガラスびん１の中心軸５と平行な方向で昇降移動する。 When the positioning unit 76 is moved by the second moving mechanism 74, the positioning unit 76 moves up and down in a direction parallel to the central axis 5 of the glass bottle 1 at the rotation position 14.
　位置決め部７６は、棒状部材の先端に、ガラスびん１の口部２の側面２ａに接触する第１位置決め面７６ａと、口部２の天面２ｂに接触する第２位置決め面７６ｂと、を含む。位置決め部７６の簡易な構成で確実に位置決めを実行できる。第１位置決め面７６ａは鉛直方向に延びる面であり、第２位置決め面７６ｂは水平方向に延びる面である。 The positioning portion 76 includes a first positioning surface 76a that contacts the side surface 2a of the mouth portion 2 of the glass bottle 1 and a second positioning surface 76b that contacts the top surface 2b of the mouth portion 2 at the tip of the rod-shaped member. . Positioning can be reliably executed with a simple configuration of the positioning portion 76. The first positioning surface 76a is a surface extending in the vertical direction, and the second positioning surface 76b is a surface extending in the horizontal direction.
　位置決め部７６は、第１受光部４０（第１、第２発光部２０，３０及び他の受光部４１～４３，５０～５３も同様）の位置決め後に、搬送経路１２を搬送されるガラスびん１と干渉しない位置へ移動可能である。位置決め部７６と連続して検査されるガラスびん１との干渉を防止することができる。位置決め部７６は、例えば、図８に矢印で示すように、取付部７０の上方から抜き出すことで搬送されるガラスびん１との干渉を防止してもよい。 The positioning unit 76 is a glass bottle 1 that is transported through the transport path 12 after positioning the first light receiving unit 40 (the same applies to the first and second light emitting units 20 and 30 and the other light receiving units 41 to 43 and 50 to 53). It is possible to move to a position where it does not interfere with. Interference with the glass bottle 1 inspected continuously with the positioning portion 76 can be prevented. For example, as shown by an arrow in FIG. 8, the positioning portion 76 may prevent interference with the glass bottle 1 being conveyed by being extracted from above the attachment portion 70.
　第１移動機構７２及び第２移動機構７４は、手動ボールねじ機構を用いたが、電動ボールねじ機構を用いてもよいし、他のアクチュエータを用いてもよい。 The first moving mechanism 72 and the second moving mechanism 74 used manual ball screw mechanisms, but may use electric ball screw mechanisms or other actuators.
　４．検査方法
　図１に示すように、第１ユニット１１ａ及び第２ユニット１１ｂの自転位置１４に搬送されたガラスびん１は図示しない自転用電動モータにより中心軸５の周りに自転しながら垂直びり及び水平びり検査が行われる。以下の説明では図１～図４を用いて、第２ユニット１１ｂについて説明するが、基本的な検査方法は第１ユニット１１ａも同様である。また、上述した通り第２ユニット１１ｂには複数の受光部４０～４３，５０～５３が含まれるが、説明を簡略化するために第１受光部４０及び第２受光部５０について説明する。 4). Inspection Method As shown in FIG. 1, the glass bottle 1 conveyed to the rotation position 14 of the first unit 11a and the second unit 11b is rotated around the central axis 5 by a rotation electric motor (not shown) while being vertical and horizontal. A slip inspection is performed. In the following description, the second unit 11b will be described with reference to FIGS. 1 to 4, but the basic inspection method is the same for the first unit 11a. As described above, the second unit 11b includes a plurality of light receiving units 40 to 43 and 50 to 53. The first light receiving unit 40 and the second light receiving unit 50 will be described in order to simplify the description.
　図２に示すように、第２ユニット１１ｂの自転位置１４では第１発光部２０及び第２発光部３０がガラスびん１の口部２に向けて可視光及び赤外光を照射する。制御部６２は、回転検出部６８の出力信号により、自転の回転角度に同期して第１受光部４０及び第２受光部５０で口部２を連続撮像させる。 As shown in FIG. 2, the first light emitting unit 20 and the second light emitting unit 30 irradiate the mouth 2 of the glass bottle 1 with visible light and infrared light at the rotation position 14 of the second unit 11b. The control unit 62 causes the first light receiving unit 40 and the second light receiving unit 50 to continuously image the mouth portion 2 in synchronization with the rotation angle of rotation by the output signal of the rotation detection unit 68.
　第１受光部４０及び第２受光部５０により撮像された画像は画像処理部６６により処理される。より具体的には、第１受光部４０及び第２受光部５０では、第１発光部２０及び第２発光部３０からの光がガラスびん１の口部２に入射し、口部２からの屈折光が第１受光部４０及び第２受光部５０により撮像され、撮像された画像が画像処理部６６により所定の階調（例えば２５６階調）の明るさに変換される。口部２にびりがあった場合、口部２に入射した光はびりの亀裂面で屈折し、この屈折光が画像処理部６６で他の画像部分より明るい領域（高い階調の領域）として認識される。 The images captured by the first light receiving unit 40 and the second light receiving unit 50 are processed by the image processing unit 66. More specifically, in the first light receiving unit 40 and the second light receiving unit 50, light from the first light emitting unit 20 and the second light emitting unit 30 is incident on the mouth part 2 of the glass bottle 1 and is emitted from the mouth part 2. The refracted light is picked up by the first light receiving unit 40 and the second light receiving unit 50, and the picked-up image is converted into brightness of a predetermined gradation (for example, 256 gradations) by the image processing unit 66. When there is a chatter on the mouth 2, the light incident on the mouth 2 is refracted at the crack surface of the chatter, and this refracted light is brightened as an area (high gradation area) by the image processor 66 than other image parts. Be recognized.
　第１受光部４０及び第２受光部５０の撮像領域は、図４に破線で示した領域であるが、その撮像領域の中でも特にびりの発生し易い部分にはゲートと呼ばれる他の部分よりも所定の明るさを有する小さな画素数をしきい値として設定することができる。ゲートによって所定部分の検出精度を向上させるためである。ゲートは１つの撮像領域の中に複数設けられてもよい。口部２におけるゲートを設ける部分としては、例えば、側面２ａにおける天面２ｂから下側に０ｍｍ～５ｍｍまでの範囲や、スカート部３ａから下側に０ｍｍ～５ｍｍの範囲等がある。 The imaging regions of the first light receiving unit 40 and the second light receiving unit 50 are regions indicated by broken lines in FIG. 4, but in the imaging region, the portion where the vibration is particularly likely to occur is more than the other portion called the gate. A small number of pixels having a predetermined brightness can be set as the threshold value. This is because the detection accuracy of the predetermined portion is improved by the gate. A plurality of gates may be provided in one imaging region. Examples of the portion where the gate is provided in the mouth portion 2 include a range from 0 mm to 5 mm below the top surface 2b of the side surface 2a, and a range from 0 mm to 5 mm below the skirt portion 3a.
　次に、判定部６３は、単位画素ごとに所定階調に変換された画像とテンプレートとを比較（減算）し、画像がテンプレートよりも明るい検出体を抽出する。判定部６３は、抽出された検出体が第１受光部４０の検査領域で設定された減算後の所定の明るさ（二値化した値）のしきい値を超えかつ所定の面積（画素数）のしきい値を超えていた場合に、口部２にびりがあると判定する。逆に、判定部６３は、当該しきい値の少なくとも一方を超えていない場合に、口部２にびりがないと判定する。 Next, the determination unit 63 compares (subtracts) the image converted to a predetermined gradation for each unit pixel and the template, and extracts a detection object whose image is brighter than the template. The determination unit 63 exceeds the threshold value of the predetermined brightness (binarized value) after subtraction set in the inspection region of the first light receiving unit 40 and the extracted detection body 63 has a predetermined area (number of pixels). ) Is exceeded, it is determined that there is a chatter in the mouth 2. Conversely, the determination unit 63 determines that there is no chatter in the mouth 2 when at least one of the threshold values is not exceeded.
　びりがあると判定されたガラスびん１は、搬出口１９から次工程へ搬送されずにラインから取り出され、不良品として処理される。 The glass bottle 1 determined to have chatter is taken out of the line without being transferred from the carry-out port 19 to the next process, and is processed as a defective product.
　５．テンプレート
　上記検査方法に用いるテンプレートについて説明する。 5). Template A template used in the inspection method will be described.
　まず、テンプレート作成部６４は、所定本数（例えば２０本程度）の良品のガラスびん１のみを上述の検査時と同様に撮像して、検査対象となるガラスびん１のための新たなテンプレートを第１受光部４０及び第２受光部５０のそれぞれに作成する。新たなテンプレートでは、良品のガラスびん１だけが対象となるため、単位画素ごとの輝度をそのまま反映させる。第１受光部４０及び第２受光部５０のそれぞれに作成された新たなテンプレートは、テンプレート記憶部６５に記憶される。 First, the template creation unit 64 images only a predetermined number (for example, about 20) of non-defective glass bottles 1 in the same manner as in the above-described inspection, and creates a new template for the glass bottle 1 to be inspected. It is created for each of the first light receiving unit 40 and the second light receiving unit 50. In the new template, since only the non-defective glass bottle 1 is targeted, the luminance for each unit pixel is reflected as it is. New templates created in each of the first light receiving unit 40 and the second light receiving unit 50 are stored in the template storage unit 65.
　次に、上記４で説明したように、テンプレート記憶部６５に記憶されたテンプレートと新たに撮像された画像とを比較しながらガラスびん１ごとに実際の検査が行われる。 Next, as described in 4 above, the actual inspection is performed for each glass bottle 1 while comparing the template stored in the template storage unit 65 with the newly captured image.
　そして、テンプレートは、検査が進む間に更新される。テンプレートの更新は、所定本数の検査が行われるたびに更新することができる。すなわち、良品のガラスびん１が所定本数になったらその所定本数分の輝度の分布をテンプレートに反映させることで更新を行う。テンプレートに反映させる所定本数は、検査が開始された初期は少なく（例えば６０本）、検査が進むにつれて多く（例えば２５０本）なるように設定できる。また、テンプレートに反映する所定本数に満たない場合でも所定更新時間（例えば２０分間）が経過した場合にもその間に得られた良品の本数だけの輝度の分布でテンプレートを更新する。生産トラブルにより生産が一時的に停止した場合にはガラスびん１の状態も変化することがあるから、その変化した状態のガラスびん１の影響をテンプレートに大きく反映させないためである。 And the template is updated as the inspection proceeds. The template can be updated each time a predetermined number of inspections are performed. That is, when the number of non-defective glass bottles 1 reaches a predetermined number, updating is performed by reflecting the luminance distribution for the predetermined number in the template. The predetermined number to be reflected in the template can be set to be small (for example, 60) at the beginning of the inspection and to increase (for example, 250) as the inspection proceeds. Further, even when the predetermined number of reflections is less than the predetermined number reflected in the template, the template is updated with the luminance distribution corresponding to the number of non-defective products obtained during the predetermined update time (for example, 20 minutes). This is because when the production is temporarily stopped due to a production trouble, the state of the glass bottle 1 may also change, so that the influence of the changed state of the glass bottle 1 is not greatly reflected in the template.
　テンプレートは、生産（検査）開始から更新を重ねるたびにテンプレートに反映させる良品のガラスびん１の本数を増やし、かつテンプレートに反映させる良品の分布における輝度の反映度合を弱めていく。生産を継続する間に金型の状態等も変化するため、ガラスびん１の形状等もわずかに変化する。そのため、その変化後の状態だけのテンプレートに変更したり、変化後の状態を強くテンプレートに反映したりしてしまうと、良品排除率が大きくなる傾向がある。テンプレートの具体的な反映の方法としては、例えば、表１に示すような更新方法を採用することができる。 The template increases the number of non-defective glass bottles 1 to be reflected in the template every time it is updated from the start of production (inspection), and weakens the degree of reflection of brightness in the non-defective product distribution to be reflected in the template. Since the state of the mold changes while production is continued, the shape of the glass bottle 1 also slightly changes. For this reason, if the template is changed to a template having only the changed state, or if the changed state is strongly reflected in the template, the non-defective product rejection rate tends to increase. As a specific method of reflecting the template, for example, an update method as shown in Table 1 can be adopted.

　表１に示すように、新規テンプレートは、良品のガラスびん１を検査装置１０で２０本検査して、画像処理部６６で画像処理した輝度の分布に基づいて作成する。更新１回目のテンプレートは、検査開始から６０本分の良品のガラスびん１の輝度の分布を新規テンプレートに反映させる。具体的には、６０本分の輝度の分布と新規テンプレートとの差分の光の分布だけを新規テンプレートに加算することで反映させる。その際の各単位画素数における輝度の加算率（新規テンプレートより明るい部分の加算率）は１００％として１２８階調（２５６階調の内）までを加算限界値と設定し、また輝度の減算率（新規テンプレートより暗い部分の減算率）を７０％として１２８階調（２５６階調の内）を減算限界値と設定した。更新後の検査装置１０による検査は更新後のテンプレートで行う。更新２回目、更新３回目と更新回数が増えると、加算率も減算率も小さくなり、少しずつその更新までの本数分に現れた輝度の分布を更新テンプレートに反映させる。連続生産による金型の状態の変化（型温、離型剤等）による影響をテンプレートに強く反映させないためである。 As shown in Table 1, a new template is created based on the luminance distribution obtained by inspecting 20 non-defective glass bottles 1 with the inspection apparatus 10 and performing image processing with the image processing unit 66. The first updated template reflects the luminance distribution of 60 non-defective glass bottles 1 from the start of inspection in the new template. Specifically, only the light distribution of the difference between the luminance distribution for 60 lines and the new template is reflected by adding to the new template. In this case, the luminance addition rate (addition rate of the brighter part than the new template) in each unit pixel number is set to 100%, and 128 gradations (of 256 gradations) are set as addition limit values, and the luminance subtraction rate The subtraction limit value was set to 128 gradations (of 256 gradations) with 70% being the subtraction rate of the darker part than the new template. The inspection by the updated inspection apparatus 10 is performed with the updated template. As the number of updates increases, such as the second update and the third update, the addition rate and the subtraction rate become smaller, and the luminance distribution that appears in the number up to the update is gradually reflected in the update template. This is because the influence of the change in the mold state (mold temperature, release agent, etc.) due to continuous production is not strongly reflected in the template.
　更新５回目以降は、更新対象となるガラスびん１の本数が２５０本未満であっても更新間隔（第４回目の更新からの経過時間）の２０分を経過した場合にはその時点までの本数を対象にテンプレートを更新する。生産ラインの状態（停止や生産量の低下など）による影響をテンプレートに強く反映させないためである。 From the fifth update onwards, even if the number of glass bottles 1 to be updated is less than 250, if the update interval (elapsed time since the fourth update) has passed 20 minutes, the number up to that point Update the template for. This is because the template does not strongly reflect the effects of the production line status (stopped, decreased production, etc.).
