Description

上記の課題を解決するため、請求項１に係る発明は、回転刃と固定刃とからなるロータリカッタと、前記回転刃または前記固定刃の相手方に対する位置を調整する位置調整機構とを備え、前記回転刃及び前記固定刃は、それぞれの刃先が前記回転刃の回転軸を中心軸とした円筒面上に形成されており、前記固定刃及び前記回転刃の少なくとも一方は、相手方の刃先が摺接可能な円弧面を有しており、前記固定刃の刃先または前記回転刃の刃先を前記回転刃の回転軸に対して傾斜させた状態で形成することによって、シャー角を付けており、前記位置調整機構は、前記回転刃または前記固定刃を相手方に対して接近離反可能にスライドさせるスライド面を有する支持部材と、前記回転刃または前記固定刃を相手方に対して押し出す押出部材とを有し、前記押出部材を前記回転刃または前記固定刃に当接させて押し出すことによって、前記固定刃及び前記回転刃の一方の刃先を他方の円弧面に当接させて、前記回転刃または前記固定刃の位置調整を行うように構成したことを特徴とするフィルム切断ユニットを提供するものである。
請求項２に係る発明は、請求項１に記載のフィルム切断ユニットにおいて、前記位置調整機構は、前記押出部材をその押出方向に付勢する付勢手段を有し、前記付勢手段の付勢力を利用して、前記回転刃または前記固定刃に衝撃を付与するように、前記押出部材を前記回転刃または前記固定刃に当接させて押し出すことによって、前記固定刃及び前記回転刃の一方の刃先を他方の円弧面に当接させて、前記回転刃または前記固定刃の位置調整を行うように構成したものである。 In order to solve the above-mentioned problem, the invention according to claim 1 includes a rotary cutter including a rotary blade and a fixed blade, and a position adjustment mechanism that adjusts a position of the rotary blade or the fixed blade with respect to a counterpart. Each of the rotary blade and the fixed blade is formed on a cylindrical surface whose center axis is the rotation axis of the rotary blade, and at least one of the fixed blade and the rotary blade is in sliding contact with the other blade edge. A circular arc surface capable of forming a shear angle by forming the blade edge of the fixed blade or the blade edge of the rotary blade in an inclined state with respect to the rotation axis of the rotary blade, and the position adjusting mechanism includes a support member having the rotary blade or the fixed blade on the slide surface to approach away can slide relative to the other party, and a pushing member for pushing the rotary blade or the fixed blade relative to the other party And, by extruding the extrusion member is brought into contact with the rotary blade or the fixed blade, the fixed blade and one cutting edge is brought into contact with the other circular arc surface of the rotary blade, the rotary blade or the fixed The present invention provides a film cutting unit configured to adjust the position of a blade.
According to a second aspect of the present invention, in the film cutting unit according to the first aspect, the position adjusting mechanism includes a biasing unit that biases the pushing member in the pushing direction, and the biasing force of the biasing unit. The pushing member is brought into contact with the rotating blade or the fixed blade and pushed out so as to give an impact to the rotating blade or the fixed blade. The blade edge is brought into contact with the other arc surface to adjust the position of the rotary blade or the fixed blade.

また、請求項２に係る発明のフィルム切断ユニットに搭載された位置調整機構は、付勢手段の付勢力を利用して、回転刃または固定刃に衝撃を付与するように、押出部材を回転刃または固定刃に当接させて押し出すことによって、固定刃及び回転刃の一方の刃先を他方の円弧面に当接させて、回転刃または固定刃の位置調整を行うように構成されているので、回転刃の刃先と固定刃の刃先の隙間が小さくなりすぎたり、大きくなりすぎたりすることがないと共に、作業者による調整作業にばらつきがなく、経験の少ない作業者が調整作業を行っても、熟練作業者と同様に、常時、適正な隙間寸法に調整することができる。 Further, the position adjusting mechanism mounted on the film cutting unit of the invention according to claim 2 uses the urging force of the urging means to apply the pushing member to the rotary blade so as to give an impact to the rotary blade or the fixed blade. Or, it is configured to adjust the position of the rotary blade or the fixed blade by bringing one of the fixed blade and the rotary blade into contact with the other circular arc surface by pushing it against the fixed blade. The gap between the blade edge of the rotary blade and the blade edge of the fixed blade does not become too small or too large, and there is no variation in the adjustment work by the operator, even if an inexperienced operator performs the adjustment work, As with skilled workers, it can always be adjusted to an appropriate gap size.
