Description

【0001】
【発明の属する技術分野】
本発明は、例えば被検査体に混入した金属物を検出する検出ヘッドと、検出ヘッドと搬送コンベアを組み合わせた金属検出機に係るものであり、特に、被検査体の搬送を円滑に行え製造が容易で衛生的な金属検出ヘッド及び金属検出機に関する。
【0002】
【従来の技術】
金属検出機は、大別して検出ヘッドと搬送コンベアによって構成され、搬送コンベアで被検査体を検出ヘッド部分を通過させ、被検査体に混入された金属が検査磁界に与える変化に基づき被検査体内の金属の混入を検出する。
【0003】
図5はこの金属検出機の正断面図、図6は同側断面図である。図示のように、検出ヘッド50は略ロ字型であり内部に送信コイル及び受信コイルからなる磁気センサが設けられている。
この開口部は検査空間Sとされ、検査空間S内に搬送コンベア51が貫通するよう配置されていて、被検査体Wを通過させる構成である。
【0004】
搬送コンベア51は、両端に設けられたローラ52,52間に無端ベルト53が張架された構成であり、ベルト53の搬送面53a側の下面には受け板54が設けられている。
そして、この搬送コンベア51には、検出ヘッド50部分におけるベルト53の搬送面53aと折り返し面53bをできるだけ近設させるテンションローラ55,55が設けられている。また、ベルト53は検出ヘッド50の検査空間S内部で下端側に近設するよう配置されている。これにより、検査空間Sを有効に利用し金属物の検出精度を向上できる。
【0005】
ここで、清掃時や被検査物の水分がベルト53に付着する等で、ベルト53と受け板54との間に水が混入すると、この水の表面張力によりベルト53が受け板54に貼り付きやすくなった。ベルト53と検出ヘッド50の下面部分50aとの隙間においても同様の問題が生じる。
これらベルト53の貼り付きが生じると、最悪ベルト53を搬送駆動できなかった。
【0006】
このため、搬送コンベア51の受け板54上面には、ベルト53の搬送が円滑となるようベルト53の移動方向に沿った樹脂製の低摩擦テープ57aが複数設けられている。
【0007】
また、検出ヘッド50の検査空間S下面は、ベルト53の折り返し面53bと近設しているため、この折り返し面53bが接触することがある。即ち、ベルト53の折り返し面53bは、距離が離れたテンションローラ55のみで張力が加えられた状態であるため、検査空間S部分で上下にふらつきやすい。
よって、検出ヘッド50の検査空間S下面部分50aにもベルト53の移動方向に沿った樹脂製の低摩擦テープ57bが複数設けられている。
【0008】
【発明が解決しようとする課題】
しかしながら、上記受け板54,検出ヘッド50に設けられる低摩擦テープ57a,57bは、両面テープや接着剤等が用いられていたため、複数本を張りつける製造時に手間がかかった。
また、このように貼り付けた構成であると、低摩擦テープ57a,57bの端面や隙間にゴミが付着し易く、また、部分的に剥がれた箇所からゴミが入り込みやすく不衛生となった。
特に、被検査体Wが食品である場合には、衛生的でなければならず、定期的な清掃が必要となるが、この清掃で隙間が生じたり、隙間のゴミを簡単に取り除くことができなかった。
【0009】
本発明は、上記課題を解決するためになされたものであり、被検査体の搬送を円滑に行え製造が容易で衛生的な金属検出ヘッド及び金属検出機を提供することを目的としている。
【0010】
【課題を解決するための手段】
上記目的を達成するため、本発明の金属検出ヘッドは、請求項1記載のように、磁気センサにより検査空間(S)に発生させた検査磁界を受信して前記検査空間内の金属の有無を検出する金属検出機の金属検出ヘッドにおいて、
前記磁気センサを収容し、前記検査空間に面する開放面のうち、搬送コンベア(6)の折り返し面(6b)に面する部分(14a)には、該搬送コンベアの搬送移動方向に沿って連続し、かつ端部(R1,R2)の角が円弧状に丸められた凹溝(15)が一体成形により複数形成された化粧板(14)が設けられたことを特徴とする。
【0012】
また、本発明の金属検出機は、請求項記載のように、請求項1記載の検出ヘッドの検査空間(S)内には、搬送面上に載置された物品を搬送する搬送コンベアが通過するよう配置され、該搬送コンベアは、ベルトの搬送面下面に設けられ、該ベルトの搬送移動方向に沿って連続する凹溝が一体成形により複数形成された受け板が設けられていて、
前記物品を搬送しながら前記金属検出ヘッドで物品内の金属物の混入を検出することを特徴とする。
【0013】
上記の金属検出機は、搬送コンベア上の物品を搬送させると、途中の金属検出ヘッドを通過する際に内部の金属物を検出することができる。
検出ヘッドには、検査空間Sの開放面に面する化粧板14aには、ベルト6の搬送方向に沿って凹溝15が連続形成されており、ベルト6が接触しても搬送を妨げることがなく円滑な搬送が行える。
また、ベルト6の搬送面6aを支持する受け板7にもベルト6の搬送方向に沿って凹溝10が連続形成されており、ベルト6の搬送を円滑に行える。
これら凹溝10,15は、化粧板14a,受け板7に一体形成されたものであり、端部にゴミが滞留することなく、また、清掃を容易に行え清潔に保てる。
【0014】
【発明の実施の形態】
図1は本発明の金属検出機を示す正断面図である。
この金属検出機1は、大略して検出ヘッド2と、搬送コンベア3で構成されており、基本構成は従来技術の説明と同様である。
【0015】
検出ヘッド2は、搬送コンベア3の搬送方向の略中央位置に設けられており、この検出ヘッド2は略ロ字型の開口部を有し、内部に送信コイル及び受信コイルからなる磁気センサが設けられている。
検出ヘッド2の開口部は検査空間Sとされ、この検査空間S内を搬送コンベア3が貫通するよう配置されており、被検査体Wが通過可能に構成されている。
【0016】
搬送コンベア3は、両端の駆動ローラ5a,従動ローラ5b間に無端ベルト6が張架された構成であり、ベルト6の搬送面6a側の下面には受け板7が設けられている。
そして、この搬送コンベア3には、検出ヘッド2部分におけるベルト6の搬送面6aと折り返し面6bをできるだけ近設させるテンションローラ8,8が設けられている。また、ベルト6は検出ヘッド2の検査空間S内部で下端側に近設するよう配置されている。これにより、検査空間Sを有効に利用し、金属検出の精度を向上させている。
【0017】
図2は受け板7を示す図である同図(a)は平面図、(b)は同側断面図である。同図においてベルト6は省略されているが、一対のローラ5a,5b間に張架されている。
図示のように、搬送コンベア3の受け板7上面には、ベルト6の移動方向に沿って連続する所定深さの凹溝10が形成されている。この凹溝10は、ベルト6の幅方向に所定間隔で複数設けられており、受け板7の成形時に一体成形される。
この凹溝10は、図3の拡大断面図に示すように、端部R1,R2の角が丸められた円弧状に形成されている。これにより、凹溝10の端部R1,R2部分でのゴミの滞留を防ぐことができる。
【0018】
図2に示すように、この受け板7の両端部にそれぞれ設けられる駆動ローラ5a,従動ローラ5bのうち、駆動ローラ5aの端部にはカップリング11が設けられ、装置基台の図示しないモータの駆動軸に連結され回転力が伝達されるようになっている。
そして、この受け板7は、ローラ5a,5bとベルト6が取り付けられた状態のまま、装置から取り外すことができるようになっている。
また、受け板7の従動ローラ5bはアーム13に取り付けられており、このアーム13の回動によって、ベルト6を取り外すことができ、清掃や保守できるようになっている。
【0019】
図4は、検出ヘッド2の部分拡大斜視図である。
検出ヘッド2の検査空間S部分に面する部分には樹脂製の化粧板14が設けられる。この化粧板14は検査空間Sに面する4面をそれぞれ接着剤等で互いに接合した構成である。
この化粧板14のうち、下面の化粧板14aには、ベルト6の移動方向に沿って連続する所定深さの凹溝15が形成されている。この凹溝15は、ベルト6の幅方向に所定間隔で複数設けられており、化粧板14aの成形時に一体成形される。
この凹溝15についても、前記受け板78同様に端部R1,R2の角が丸められた円弧状に形成されている。これにより、凹溝15の端部R1,R2部分でのゴミの滞留を防ぐことができる。
【0020】
上記構成によれば、受け板7には凹溝10が一体形成されるため、ベルト6との間の接触面積を少なくしてこのベルト6の搬送移動を妨げることなく円滑に支持することができる。
また、凹溝10を備えた受け板7の製造を容易化できるようになる。また、従来の低摩擦テープの如く端面や隙間にゴミが付着することなどがなく衛生を保てる。特に、被検査体Wが食品である場合における清掃を容易に行え、清掃で隙間が生じることもない。
【0021】
また、検出ヘッド2に設けられる化粧板14の下面14aにも凹溝15が一体形成されているため、この下面4aに近設されているベルト6の折り返し面6b側が接触することがあっても、ベルト6との間の接触面積が少なく搬送移動を妨げない。
この凹溝15を備えた化粧板4は一体形成で簡単に製造できる。また、従来の低摩擦テープの如く端面や隙間にゴミが付着することなどがなく衛生を保てる。特に、被検査体Wが食品である場合における清掃を容易に行え、清掃で隙間が生じることもない。
【0022】
上記構成の金属検出機は、ベルト6の搬送面6a側を支持する受け板7と、折り返し面6b側に近設する検出ヘッド2の下面14aにそれぞれ凹溝15が形成された構成であるため、これらが相乗してベルト6の搬送を円滑にすることができる。
例え、ベルト6と受け板7との間、及びベルト6の折り返し面6bと検出ヘッド2の下面14a間にそれぞれ水が溜まっても、ベルト6の搬送移動方向に連続する凹溝10,15によって、ベルト6がこれらに張り付くことがなく、搬送を円滑に行える。
【0023】
上記実施の形態では、受け板7、化粧板14aにそれぞれ凹溝15,10を形成する構成としたが、逆に突起を形成する構成とすることもでき、受け板7、化粧板14aのいずれであっても一体形成で容易に形成でき、上記同様の作用効果を得ることができる。
【0024】
【発明の効果】
本発明の金属検出ヘッドによれば、検査空間の開放面に面する化粧板にベルトの搬送方向に沿って凹溝が連続形成され、かつ端部の角が円弧状に丸められた構成であり、ベルトを安定して搬送することができるようになる。しかも、凹溝の端部部分でのゴミの滞留を防ぐことができる。
本発明の金属検出機によれば、上記金属検出ヘッドの構成に加え、搬送コンベアのベルトの搬送面を支持する受け板にベルトの搬送方向に沿って凹溝が連続形成されており、ベルトの搬送を円滑に行える。
そして、これらの凹溝は、化粧板、及び受け板の成型時に一体成型でき、製造が容易に行える。また、凹溝の端部にゴミが滞留することなく、清掃を容易に行える。特に食品を検査対象として場合の衛生度を保つことができる。
