Abstract
Description
また、特許文献3には、コンベアベルトの両側部位に水平方向に開口するU字形断面の被支持部と、該被支持部に遊嵌する案内レールとを設け、該案内レールよってコンベアベルトを移動可能に支持する構成が開示されている。さらに、特許文献2及び3には、コンベアベルト搬送面から上方へ突出し、被搬送品の脱落を防止する落下防止板が、搬送ベルトを構成する隣り合う2本のバーに嵌合固定された構成が開示されている。
また、本発明では、隣り合う2本の棒状材の搬送方向の相対位置が固定されないので、搬送ベルトの曲がり部で、棒状材がきめ細かな曲線形状を形成できる。従って、搬送路の設計自由度を広げることができると共に、連結具に滑動面を形成しているので、該滑動面を形成するための特別な部材を必要としない。そのため、搬送ベルトの構成部材を簡素化でき、その製造費を低コスト化できる。また、連結具が2つ折りに形成され、第1の棒状材を両端部2箇所で支持するので、連結具の強度を増大できる。
これによって、搬送ベルトの側方に隣接配置されたスプロケットとの噛合が容易になる。また、歯形部は棒状材と結合された連結具の両端部に形成されているため、大きな強度を有することができる。
このように、連結具は滑動面の外側にガイド面を有しているので、搬送ベルトが案内レールから脱落するのを防止できる。また、この実施形態では、連結具は滑動面及びガイド面のみで案内レールに摺接し、特許文献3の被支持部のようにレールを囲む構成ではない。そのため、低温環境下でも案内レール間の面圧上昇や摩耗の増大を防止できると共に、搬送ベルトのたるみの修正が容易になる。
これによって、連結具と案内レールとの間に形成される摺接面の摩耗や摩耗粉の発生を抑制し、摩耗粉が搬送される食品に及ぼす悪影響を排除できる。
搬送ベルトが無端搬送路を構成するとき、無端搬送ベルトはリターン路で反転され、搬送始端部に戻る。この場合、リターン路以外の無端搬送路で、連結具は一対の滑動面のうち下方に配置された滑動面を介して案内レールに支持され、かつ一対のガイド面のうち下方に配置されたガイド面を介して案内レールにガイドされる。
これによって、連結具の内側空間に隣り合う連結具の頂部が進入しやすくなり、1個の連結具によって拘束される第1の棒状材及び第2の棒状材の搬送方向の相対変位が容易になる。そのため、搬送路が形成する曲線の自由度を広げることができる。
これによって、隣り合う一方の連結具の内部空間に他方の連結具が進入するとき、両連結具間で棒状材の長手軸方向の隙間が発生せず、両連結具の搬送方向の相対変位を円滑に行うことができる。そのため、搬送動作が滑らかに行われるので、搬送路の曲がりが容易になり、搬送路の設計自由度を広げることができると共に、搬送ベルトの搬送方向位置で搬送速度にばらつきが生じるノッキング現象を防止できる。
また、リターン路においても案内レールによって支持されるので、リターン路における搬送ベルトのたるみを防止できる。

これによって、1個の連結具62に隣り合う2本の丸棒60が拘束され、かつこれら2本の丸棒60は搬送ベルトの搬送方向の相対変位が可能である。
また、連結具62が丸棒60の1個毎に別々に設けられているので、隣り合う連結具62は互いに拘束されない。そのため、無端搬送路14の曲がり部できめ細かな曲線形状を形成でき、無端搬送路14の設計自由度を広げることができる。また、案内レール82の構造を簡素化でき、製造費を低コストにできる。
