Description
本発明は軟質ボトルに内容物、特に高粘度を充填後、口部をシール材によって密封したボトルの密封検査装置に関する。 The present invention relates to a bottle sealing inspection apparatus in which a soft bottle is filled with contents, particularly high viscosity, and a mouth portion is sealed with a sealing material.
高、中、低密度ポリエチレン、ポリプロピレン等のポリオレフィン樹脂、或いはこれらの樹脂に中間層としてエチレン−ビニルアルコール等のガスバリア性樹脂を用いて多層構成とした軟質ボトルに、マヨネーズ、ケチャップ、ソース等といった高粘度の内容物を充填し、アルミ箔及び接着樹脂から成るシール材にてボトルの口部をシールすることが一般的に行われている。この場合、シール材をボトルの口部に被せたのち、高周波誘導加熱等によりシール材をシールし、密封しているが、密封後、シール材のシール不良やピンホール等により内容物の漏洩が生じると商品価値を損なうことになる。そして、従来は、製造ライン上から定期的にボトルを抜き取り、人手によって押圧し、目視することで密封検査が行われてきた。一方、真空ポンプを用いてシール部を減圧し圧力の変化を測定してシール不良を検査する装置が提案されている（特許文献１）。 Polyolefin resins such as high, medium and low density polyethylene, polypropylene, etc., or soft bottles made of a multilayer structure using a gas barrier resin such as ethylene-vinyl alcohol as an intermediate layer for these resins, high mayonnaise, ketchup, sauce, etc. It is common practice to fill the contents of viscosity and seal the mouth of the bottle with a sealing material made of aluminum foil and adhesive resin. In this case, after the sealing material is put on the mouth of the bottle, the sealing material is sealed and sealed by high-frequency induction heating, etc., but after sealing, the contents may leak due to sealing failure or pinholes. If it occurs, the commercial value will be impaired. Conventionally, a sealing inspection has been performed by periodically removing a bottle from the production line, pressing it manually, and visually observing it. On the other hand, an apparatus for inspecting a defective seal by reducing the pressure of a seal portion using a vacuum pump and measuring a change in pressure has been proposed (Patent Document 1).
しかしながら、従来の人手による目視での密封検査は、人的な不注意による密封不良製品の見落としを避けることはできず、また、軟質ボトルは、ボトルを押圧する箇所によって、口部のシール材による密封部に加わる圧力が大きく変化し、定量的な密封検査が困難である。一方、特許文献１の検査装置は、内容物が高粘度の場合、ボトルの内部と外部との差圧が不十分で、流動性の低い内容物が漏洩経路に詰まり正確な検査ができないという問題が発生する。従って、本発明は、前記従来技術の課題を解決し、内容物、特に高粘度の内容物を充填してシール材でその口部を密封した軟質ボトルの口部の密封検査において、人的な不注意による密封不良製品の見落としを防止し、また、軟質ボトルの口部のシール材による密封部に加わる圧力を一定として定量的な密封検査が可能なボトルの密封検査装置を提供することを目的としている。 However, the conventional visual sealing inspection by hand cannot avoid oversight of poorly sealed products due to human carelessness, and soft bottles depend on the sealing material of the mouth depending on the location where the bottle is pressed. The pressure applied to the sealing part changes greatly, and quantitative sealing inspection is difficult. On the other hand, in the inspection apparatus of Patent Document 1, when the content is high viscosity, the differential pressure between the inside and the outside of the bottle is insufficient, and the content with low fluidity is clogged in the leakage path and cannot be accurately inspected. Will occur. Therefore, the present invention solves the above-mentioned problems of the prior art, and in the sealing inspection of the mouth of a soft bottle in which the contents, in particular, the contents of high viscosity are filled and the mouth is sealed with a sealing material, An object of the present invention is to provide a bottle sealing inspection device that prevents inadvertent sealing failure from being overlooked and that enables quantitative sealing inspection with a constant pressure applied to the sealing portion by the sealing material of the soft bottle mouth. It is said.
本発明のボトルの密封検査装置は、口部から横断面積が拡大して胴部に連接する肩部を有する軟質ボトルに、内容物を充填後、口部をシール材によって密封したボトルの密封検査装置において、前記ボトルを正立状態で保持する支持枠、前記ボトルと支持枠を搬送するベルトコンベア、該ベルトコンベア上の支持枠によって搬送されるボトルの肩部に位置し、該肩部を押圧するように対称的に配置され、該ベルトコンベアと同じ速度で回動する一対の断面円形のベルト、及び前記シール材によって密封したボトルの口部を上方から撮像し、画像処理して内容物の漏洩の有無を判定する検出手段とを有することを特徴としている。
The bottle sealing inspection device of the present invention is a bottle sealing inspection in which the mouth is sealed with a sealing material after filling the contents into a soft bottle having a shoulder that is connected to the body with a cross-sectional area enlarged from the mouth. in the device, located in the shoulder portion of the bottle being conveyed support frame for holding the bottle in upright position, a belt conveyor for conveying the bottle and the support frame, the support frame on the belt conveyor, pressing the shoulder portion A pair of circular belts that are arranged symmetrically and rotate at the same speed as the belt conveyor, and the mouth of the bottle sealed by the sealing material are imaged from above, and image processing is performed on the contents. And detecting means for determining the presence or absence of leakage.
本発明のボトルの密封検査装置によれば、軟質ボトルに内容物、特に高粘度の内容物を充填し、シール材で口部を密封した口部の密封検査において、人的な不注意による密封不良製品の見落としを防止し、また、軟質ボトルの口部のシール材による密封部に加わる圧力を一定として定量的な密封検査が可能となる。 According to the bottle sealing inspection apparatus of the present invention, in a sealing inspection of a mouth portion in which a soft bottle is filled with contents, particularly a high-viscosity content, and the mouth portion is sealed with a sealing material, sealing by human carelessness is performed. Defective products can be prevented from being overlooked, and quantitative sealing inspection can be performed with a constant pressure applied to the sealing portion by the sealing material at the mouth of the soft bottle.
以下、本発明の実施形態によるボトルの密封検査装置を、図１乃至図３を参照して説明する。図１は、本発明に係わるボトルの密封検査装置（以下、検査装置）の正面図である。図１に示すように、検査装置１全体は支持台２に支持されている。前記支持台２の上にはベルトコンベア３が設置され、ベルトコンベア３上に支持枠４を載置し、内容物を充填しその口部をシール材で密封したボトルＢを口部が上となる正立状態で支持枠４に挿入され、ベルトコンベア３によって後述する検出手段１０へ搬送される。ベルトコンベア３の両側にガイド５が設置され、このガイド５は、支持枠４をベルトコンベア３で搬送する際に支持枠４がベルトコンベア３上でズレないように位置決めを行う。 Hereinafter, a bottle sealing inspection apparatus according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. FIG. 1 is a front view of a bottle sealing inspection apparatus (hereinafter referred to as an inspection apparatus) according to the present invention. As shown in FIG. 1, the entire inspection apparatus 1 is supported by a support base 2. A belt conveyor 3 is installed on the support base 2, a support frame 4 is placed on the belt conveyor 3, bottle B is filled with the contents, and the mouth is sealed with a sealing material. In the upright state, it is inserted into the support frame 4 and conveyed by the belt conveyor 3 to the detection means 10 described later. Is installed guide 5 on each side of the belt conveyor 3, the guide 5, the support frame 4 to position so as not shifted on the belt conveyor 3 in transporting the support frame 4 by a belt conveyor 3.
そして、ベルトコンベア３上の支持枠４によって搬送されるボトルＢは、コンベア３の上方、両側、且つボトルＢの肩部に位置するように対称的に配置された一対のベルト６により、その肩部を押圧されながら搬送される。尚、ここでの肩部とは、ボトルＢの口部から横断面積が拡大していき胴部に連接する領域を指す。ボトルＢの肩部を押圧する一対のベルト６は、本実施形態ではボトルＢへの傷付きを防止するため、断面円形、直径１０ｍｍのポリウレタン製の丸ベルトとした。一対のベルト６は、それぞれ４個のプーリ７に装着され、図示しない適宜手段により、ベルト６がコンベア３と同じ速度で回動するように駆動される。又、ボトルＢを押圧する区間では、一定の押圧がかかるように、ベルト６は複数の小径プーリ１６で支えられている。前記プーリ７は、高さ方向の位置を調節自在なブラケット８に装着され、更に、ブラケット８はボトルＢに対して幅方向の位置を調節可能なブラケット９に装着されている。一対のベルト６同士の間隔は、ベルト６が当接するボトルＢの肩部の寸法よりも狭く設定されており、ボトル形状、容量、内容物に応じて適宜ブラケット８、９で調整される。 The bottles B conveyed by the support frame 4 on the belt conveyor 3 are shouldered by a pair of belts 6 which are symmetrically arranged so as to be positioned on the shoulders of the bottles B above and on both sides of the conveyor 3. It is conveyed while being pressed. Here, the shoulder portion refers to a region where the cross-sectional area increases from the mouth portion of the bottle B and is connected to the trunk portion. In the present embodiment, the pair of belts 6 that press the shoulders of the bottle B is a round belt made of polyurethane having a circular cross section and a diameter of 10 mm in order to prevent the bottle B from being damaged. The pair of belts 6 are respectively attached to four pulleys 7 and are driven by appropriate means (not shown) so that the belt 6 rotates at the same speed as the conveyor 3. Further, in the section where the bottle B is pressed, the belt 6 is supported by a plurality of small-diameter pulleys 16 so that a constant pressure is applied. The pulley 7 is mounted on a bracket 8 whose position in the height direction can be adjusted, and the bracket 8 is mounted on a bracket 9 whose position in the width direction with respect to the bottle B can be adjusted. The distance between the pair of belts 6 is set to be narrower than the size of the shoulder portion of the bottle B with which the belt 6 abuts, and is appropriately adjusted by the brackets 8 and 9 according to the bottle shape, capacity, and contents.
本実施形態では、ベルト６をボトルＢの口部端からおおよそ６０ｍｍの下の箇所に設置し、内容物が充填されたボトルＢの幅が約５０ｍｍとなる箇所において約４０ｍｍの間隔で対向させている。このように、ボトルＢ内を陽圧状態とすることにより、シール材によって密封されたボトルＢの口部に、シール材のシール不良やピンホール等が有ればその部分から内容物が漏洩するため、このシール不良、或いはピンホール等から漏洩した内容物の有無を、後述する検出手段１０で検出して、内容物が検出されたボトル１を不良品として選別部８にて排除する。 In this embodiment, the belt 6 is installed at a location approximately 60 mm below the mouth end of the bottle B, and the bottle B filled with the contents is opposed at an interval of approximately 40 mm at a location where the width is approximately 50 mm. Yes. Thus, by making the inside of the bottle B into a positive pressure state, if there is a sealing failure of the sealing material or a pinhole or the like in the mouth of the bottle B sealed with the sealing material, the contents leak from that portion. Therefore, the presence or absence of the contents leaked from the seal failure or the pinhole is detected by the detecting means 10 described later, and the sorting unit 8 excludes the bottle 1 from which the contents are detected as a defective product.
検出手段１０は、ＣＣＤカメラ１１、リング照明１２、およびコントローラ１３で構成されている。図１に示す通りＣＣＤカメラ１１とリング照明１２は天板１４に取り付けられており、ＣＣＤカメラ１１による撮像の中心と、リング照明１２の中心がボトルＢのシール材で密封された口部の軌道上に重なるように配置される。尚、図示しないが、トリガーセンサーが、コンベア上のボトルＢが撮像位置に存在するとオンとなる位置に設置されている。そして、トリガーセンサーがオンとなると、ＣＣＤカメラ１１はボトルＢの口部の一帯を上方から撮像し、リング照明１２による反射光が撮影画像データとして取り込まれ、情報がコントローラ１３へ送られ、この撮影画像データを２値化処理等の公知の技術によって画像処理を施した後、その結果に基づいて内容物の漏洩の有無を判定する。この際、画像処理によって前述した内容物の漏洩が有ると判定された場合は、プログラマブルコントローラ１５によって、図３に示すように、選別部２０でコンベア３から不良品として排除され、内容物の漏洩が無いと判定されれば、良品として次工程へ通過する。 The detection means 10 includes a CCD camera 11, a ring illumination 12, and a controller 13. As shown in FIG. 1, the CCD camera 11 and the ring illumination 12 are attached to the top plate 14, and the center of the image taken by the CCD camera 11 and the trajectory of the mouth where the center of the ring illumination 12 is sealed with the sealing material of the bottle B. Arranged so as to overlap. Although not shown, the trigger sensor is installed at a position that is turned on when the bottle B on the conveyor exists at the imaging position. When the trigger sensor is turned on, the CCD camera 11 captures a portion of the mouth of the bottle B from above, the reflected light from the ring illumination 12 is captured as photographed image data, and information is sent to the controller 13 for this photographing. After image processing is performed on the image data by a known technique such as binarization processing, the presence or absence of content leakage is determined based on the result. At this time, if it is determined by the image processing that the above-described content leakage has occurred, the programmable controller 15 removes the content from the conveyor 3 as a defective product by the sorting unit 20 as shown in FIG. If it is determined that there is no, it passes to the next process as a non-defective product.
また、選別部８は、ボトルＢが不良であると判定されると、プログラマブルコントローラ１５の指令により適宜タイミングでアクチュエータ２１が作動し、支持枠４に挿入されたボトルＢの進路がベルトコンベア３から不良品回収箱２２へ向けて変更され、支持枠４とボトルＢが回収される。このとき、作業者に音、光等で不良の警告をするようにしても良い。その後、ボトル１は適宜手段で処分される。尚、本発明の検査装置は、１分間当たり１５０本前後検査可能である。 Further, when it is determined that the bottle B is defective, the sorting unit 8 operates the actuator 21 at an appropriate timing according to a command from the programmable controller 15, and the path of the bottle B inserted into the support frame 4 is moved from the belt conveyor 3. The change is made toward the defective product collection box 22, and the support frame 4 and the bottle B are collected. At this time, the operator may be warned of a failure by sound, light or the like. Thereafter, the bottle 1 is disposed of by appropriate means. The inspection apparatus of the present invention can inspect about 150 pieces per minute.
本発明のボトルの密封検査装置は、前述したように、ボトルＢの肩部を押圧するという簡単な構成によって、全品を確実、且つ容易に検査でき、人的な不注意による密封不良製品の見落としが防止され、また、軟質ボトルの口部のシール材による密封部に加わる圧力を一定にして定量的な密封検査が可能となる。このため、製品の密封性に対する信頼性を向上させることができる。尚、本発明のボトルの密封検査装置が適用される内容物は、マヨネーズ、ケチャップ、ソース等の食品に限定されるものではなく、他の高粘度の内容物にも広く適用できる。 The bottle sealing inspection device of the present invention, as described above, can reliably and easily inspect all products with a simple configuration of pressing the shoulder of the bottle B, and overlooks a product with poor sealing due to human carelessness. In addition, the pressure applied to the sealing portion by the sealing material at the mouth portion of the soft bottle can be made constant, and quantitative sealing inspection can be performed. For this reason, the reliability with respect to the sealing performance of a product can be improved. The contents to which the bottle sealing inspection apparatus of the present invention is applied are not limited to foods such as mayonnaise, ketchup, sauce, etc., and can be widely applied to other high viscosity contents.
