第1面及びそれと反対側に位置する第2面を有し、少なくとも一部に樹脂材を含む複数枚のシートが重ねられた帯状のシート積層体をその長手方向にわたって第1面上に支持する支持部材と、
前記支持部材における第2面側に配置され、かつレーザー光を集光するレンズを有する照射ヘッドとを具備し、
前記支持部材が、第2面側から照射されたレーザー光の通過可能な、前記シート積層体の幅方向に長いスリット状の開口部を有しており、
前記スリット状の開口部に対応する位置で、前記シート積層体を前記支持部材に向けて加圧する加圧ヘッドを、該支持部材における第1面側の位置に配置し、
前記加圧ヘッドは、前記スリット状の開口部に沿って配列された複数の加圧部を備え、
複数の前記加圧部は、前記シート積層体を加圧する加圧時間を個別に制御可能になっている、シート融着体の製造装置。 - 個々の前記加圧部が、前記シート積層体を押圧する押圧部と、シャフトを介して該押圧部に連結しているシリンダ機構とを備えている請求項1に記載のシート融着体の製造装置。
- 個々の前記加圧部が、前記シート積層体を押圧する押圧部と、該押圧部に連結するシャフトと、該シャフトの先端と当接するカムとを備えている請求項1に記載のシート融着体の製造装置。
- 前記支持部材が、外方を向く第1面と内方を向く第2面とを有し、かつ一方向に回転可能な円筒からなり、
前記円筒の周面に、該円筒の回転軸の軸長方向と平行な方向に一致して延びる前記スリット状の開口部が、該円筒の周方向に所定間隔を置いて複数設けられており、
前記加圧ヘッドは、前記支持部材の回転方向と同方向に、かつ該支持部材の周速と同速で、該支持部材の周面に沿って周回可能になっており、
前記加圧ヘッドは、該加圧ヘッドが前記支持部材の周面に沿って周回している間、該加圧ヘッドの前記加圧部が、前記支持部材の第1面に対して接離動作を繰り返すようになっている請求項1ないし3のいずれか一項に記載のシート融着体の製造装置。 - 前記加圧ヘッドが、複数の前記加圧部の配列方向の一端にヒンジ構造の支持部を有し、該支持部を支点として、前記支持部材の回転軸を通る面内において揺動運動が可能になっており、それによって、該加圧ヘッドが前記支持部材の第1面に対して接離動作をするようになっている請求項4に記載のシート融着体の製造装置。
- 前記加圧ヘッドが、前記支持部材の径方向に沿う往復運動が可能になっており、それによって該加圧ヘッドが前記支持部材の第1面に対して接離動作をするようになっている請求項4に記載のシート融着体の製造装置。
- 複数枚のシートの縁部が重なった状態で融着したシール縁部を有するシート融着体の製造方法であって、
第1面及びそれと反対側に位置する第2面を有する支持部材における第1面上に、少なくとも一部に樹脂材を含む複数枚のシートが重ねられた帯状のシート積層体をその長手方向にわたって支持させるとともに、該シート積層体をその幅方向にわたって加圧し、
前記支持部材における第2面側に配置され、かつレーザー光を集光するレンズを有する照射ヘッドから、該支持部材の第1面上に支持された前記シート積層体における加圧部位に向けてレーザー光を照射して、該シート積層体をその幅方向にわたって分断するのと同時に、この分断の縁部を重なった状態で融着して前記シール縁部を形成する工程を有し、
前記加圧部位に前記レーザー光を照射してから該加圧部位の加圧状態が解除されるまでの時間を、前記シート積層体の幅方向において異ならせる、シート融着体の製造方法。 - 加圧状態下にある前記シート積層体の分断予定部分に対して、レーザー光を、該シート積層体の幅方向に沿って走査しながら照射し、そのときに、レーザー光が照射されてから加圧状態が解除されるまでの時間が、該分断予定部分の各部において同じになるように、該分断予定部分の各部における加圧時間を調整する請求項7に記載のシート融着体の製造方法。
