CLIP LINK MECHANISM OF SIMULTANEOUS BIAXIAL STRETCHING APPARATUS

To provide a clip link mechanism of a simultaneous biaxial stretching apparatus that reduces load while the clip link mechanism moves when a clip pitch is set to a maximum value.SOLUTION: A clip holding member provided with a guide roller (a first roller) guided by a reference rail (a first rail), a self-weight bearing roller (a first roller) and a clip, and a link supporting member provided with a guide roller (a second roller) guided by a pitch-setting rail (a second rail) and a self-weight bearing roller (a second roller) are alternately connected with a first link member and a second link member having the same length. The first link member and the second link member are connected to the clip-bearing member with a first axis member, and are connected to the link support member with a second axis member. A third link member that limits an opening angle between the first link member and the second link member to a predetermined angle or less is connected between the first link member and the second link member.SELECTED DRAWING: Figure 3 【課題】クリップピッチが最大値に設定されたときに、クリップリンク機構が移動する際の負荷を低減させる同時２軸延伸装置のクリップリンク機構を提供すること。【解決手段】基準レール（第１のレール）に案内される案内ローラ（第１のローラ）と自重受ローラ（第１のローラ）とクリップとを備えるクリップ担持部材と、ピッチ設定レール（第２のレール）に案内される案内ローラ（第２のローラ）と自重受ローラ（第２のローラ）を備えるリンク支持部材とを、同じ長さの第１のリンク部材と第２のリンク部材とで交互に接続する。第１のリンク部材及び第２のリンク部材は、第１の軸部材でクリップ担持部材に接続して、第２の軸部材でリンク支持部材に接続する。第１のリンク部材と第２のリンク部材との間には、第１のリンク部材と第２のリンク部材との開き角度を所定角度以下に制限する第３のリンク部材を接続する。【選択図】図３
