Description
ヒートシール装置は、
胴材の搬送方向に垂直な対向方向に互いに対向する一対のシールユニットを備える。一対のシールユニットは、それぞれ、ヒートシール部材と、ヒートシール部材を加熱するヒータと、を含む。
ヒートシール装置は、さらに、
胴材をヒートシール部材で挟むために、シールユニットの少なくともいずれか一方を対向方向に移動させる駆動ユニットを備える。
ヒートシール装置は、さらに、
一対のシールユニットを、搬送方向および対向方向に垂直な胴材の幅方向に移動可能に支持し、一方の前記シールユニットを、胴材の幅方向に移動させる調整ユニット、を備える。
回転可能に支持され、胴材の幅方向にのびる第1軸と、
第1軸に形成された第1雄ネジに係合する第1雌ネジを有し、一方のシールユニットに取り付けられた第1取付具と、
回転可能に支持され、第1軸と平行にのびる第2軸と、
第2軸に形成された第2雄ネジに係合する第2雌ネジを有し、他方のシールユニットに取り付けられた第2取付具と、を含んでよい。
一端において一対の第1ベベルギアによって第1軸に連結され、他端において一対の第2ベベルギアによって第2軸に連結された中継軸、をさらに含んでよい。
第1雄ネジが形成された基部と、
一方の第1ベベルギアが装着された可動部と、を含んでよい。
可動部は、
一対の第1ベベルギアが互いに噛み合う第1位置と、一対の第1ベベルギアの噛合いが解除された第2位置との間で基部に対して移動可能に、第1軸受を介して基部に連結されてよい。
可動部が第1位置および第2位置のどちらの位置にあるときも基部と一緒に回転するように、可動部および第1軸受は構成されてよい。
第1軸を回転するために操作されるハンドルを、さらに含んでよい。
可動部を第1位置へ付勢する位置決めバネをさらに含んでよい。
一方の第1ベベルギアが装着された第1端部と、
一方の第2ベベルギアが装着された第2端部と、
第1端部と第2端部との間に配置された中間部と、
第1端部と中間部とをつなぐ第1自由継手と、
第2端部と中間部とをつなぐ第2自由継手と、を含んでよい。
調整ユニット18が第2状態にされる。実施形態では、可動部261(図4)が第1位置から第2位置に移動され、調整ユニット18が第1状態から第2状態に切り替えられる。それから、ハンドル33(図4)の操作により、シールユニット12が胴材1,2の幅方向Yにシールユニット13に対して移動され、ヒートシール部材14,15の相対位置が調整される。調整の後、可動部261(図4)が位置決めバネの付勢力によって第2位置から第1位置に戻る。
調整ユニット18は、第1状態にされている。実施形態では、可動部261が位置決めバネの付勢力により、第1位置に配置されている。それから、ハンドル33の操作によって、一対のシールユニット12,13が、セットされた胴材1,2に対してその幅方向Yに移動する。このとき、作業者は、一方のヒートシール部材15を胴材1,2に対して位置調整しさえすればよい。一方のシールユニット13が移動されると、他方のシールユニット12も、シールユニット13と同じ方向に同じ距離移動されているからである。したがって、ヒートシール部材14も自動的に胴材1,2に対して位置調整されている。
調整ユニット18は、ハンドル33に代えて、第1軸26を回転させるモータを含んでよい。調整ユニット18は、さらに、胴材1,2に付されたマークを検知するマークセンサと、センサおよびモータに接続され、モータを制御するコントローラとを、含む。コントローラは、マークセンサからの検知信号に基づいてモータを制御し、一対のシールユニット12,13を一緒に移動させ、ヒートシール部材14,15を胴材1,2に対して位置調整する。
