各種液体調味料或いは液体洗剤等のための容器として、周知のとおり、樹脂フィルムから成る袋状のパウチが広く実用に供されている。そして、このようなパウチに注出口、易開封のノッチ、或いは易開封溝を形成するため、本出願人は、特許文献１に開示されている如く、樹脂フィルム、或いは樹脂フィルムを重ね合わせてヒートシールした中間パウチに、冷間で注出口などを張り出させる立体成形を行う圧縮成形、或いはこの圧縮成形に加えてフルカット加工、ハーフカット加工を行う成形ロール（回転ロール）によるロータリー加工装置を提案した。 As is well known, as a container for various liquid seasonings or liquid detergents, a bag-like pouch made of a resin film is widely used in practical use. In order to form a spout, an easy-open notch, or an easy-open groove in such a pouch, the present applicant, as disclosed in Patent Document 1, heats the resin film or the resin film superimposed on each other. A rotary processing device with compression molding that performs three-dimensional molding that projects a spout out in a cold manner on a sealed intermediate pouch, or a molding roll (rotary roll) that performs full-cut processing and half-cut processing in addition to this compression molding Proposed.
そして、前述した加工装置は一対の回転ロールを備え、一方の回転ロールの外周面に、加工金型が着脱可能に装着されている。このような回転ロールを備える加工装置においては、一方の回転ロールに装着された加工金型と他方の回転ロールとにより、樹脂フィルム、中間パウチに、前述した圧縮成形、フルカット加工、ハーフカット加工等が行われる。 And the processing apparatus mentioned above is equipped with a pair of rotation roll, and the process metal mold | die is attached to the outer peripheral surface of one rotation roll so that attachment or detachment is possible.

As a result, when a resin film or the like is processed by the processing mold and the other rotating roll, the processing mold mounted on the rotating roll is particularly transported by the resin film or the like due to the nip drag N generated between the two. It moves to the upstream side or the downstream side in the direction, and an appropriate processing force cannot be applied to the workpiece such as a resin film.
本発明は前記事実に鑑みてなされたものであり、その主たる技術的課題は、一対の回転ロールを備え、少なくとも一方の回転ロールの外周面に、加工金型が着脱可能に装着された加工装置による加工の際に、前記加工金型の回転ロールの装着面上での移動を確実に回避して、樹脂フィルム、中間パウチ等の被加工材に適正な加工力を付与することができる、新規、且つ改良された回転ロールを備える加工装置を提供することである。 The present invention has been made in view of the above-mentioned facts, and a main technical problem thereof is a processing apparatus provided with a pair of rotating rolls and having a processing mold detachably mounted on an outer peripheral surface of at least one rotating roll.

本発明の回転ロールを備える加工装置の実施形態について説明する。 Embodiment of a processing apparatus provided with the rotating roll of this invention is described.
本発明の回転ロールを備える加工装置は、前述した樹脂フィルム、中間パウチ等の被加工材に、圧縮成形、フルカット加工、或いはハーフカット加工等の加工を、例えば冷間加工で行う加工装置１０であり、図１に示すように、この加工装置１０は一対の回転ロール１６ａ、１６ｂを備え、図示しない適宜の駆動手段によって回転し、支持手段により相互にニップ（密着）力を付与した状態で回転自在に軸支される。
尚、本実施形態においては、上側の回転ロール１６ａの回転軸２２が適宜の駆動手段によって回転し、下側の回転ロール１６ｂが上側の回転ロール１６ａの後述する取付ロール１８のロール表面との間で生じるニップ（密着）力に起因して回転する。
The processing apparatus provided with the rotating roll of the present invention is a processing apparatus 10 that performs processing such as compression molding, full cut processing, or half cut processing on a workpiece such as the above-described resin film or intermediate pouch by, for example, cold processing. As shown in FIG. 1, this processing apparatus 10 includes a pair of rotating rolls 16a and 16b, is rotated by an appropriate driving means (not shown), and a nip (contact) force is applied to each other by a supporting means. It is pivotally supported.
In this embodiment, the rotary shaft 22 of the upper rotary roll 16a is rotated by an appropriate driving means, and the lower rotary roll 16b is between the roll surface of the mounting roll 18 described later of the upper rotary roll 16a. Rotates due to the nip (adhesion) force generated in
本実施形態においては、一方（上側）の回転ロール１６ａは、左右の取付ロール１８、１８と、この取り付けロール１８、１８間に取り付けられる正多角柱部材としての正四角柱部材２０、及びそれらの回転中心軸を一致させて、前記した左右の取付ロール１８、１８を超えて延びる回転軸２２と、を設けている。そして、図２に示すように、前記した正四角柱部材２０の断面の対角線の距離は、取付ロール１８、１８の直径よりも短く、加工金型２８を装着するスペースを有して、この正四角柱部材２０は、前記取付ロール１８、１８に装着されている。
また、他方の円筒型回転ロール１６ｂは、その回転中心軸を、その回転ロール１６ｂの両端部を超えて延びる回転軸２４を設けている。
In the present embodiment, one (upper) rotating roll 16a includes left and right mounting rolls 18 and 18, a regular square column member 20 as a regular polygonal column member mounted between the mounting rolls 18 and 18, and their rotation. A rotating shaft 22 extending beyond the left and right mounting rolls 18 and 18 is provided with the center axis aligned. And as shown in FIG. 2, the distance of the diagonal of the cross section of the above-mentioned regular square column member 20 is shorter than the diameter of the mounting rolls 18 and 18 and has a space for mounting the processing mold 28, and this regular square column The member 20 is mounted on the mounting rolls 18 and 18.
Further, the other cylindrical rotary roll 16b is provided with a rotary shaft 24 whose central axis of rotation extends beyond both ends of the rotary roll 16b.
また、前述した正四角柱部材２０の隣接する外側面２５ａと２５ｂは、図２及び図３に示すように、正四角柱部材２０の接続部の一つに頂角Ａ（９０度）を形成して装着角部２６とし、この装着角部２６を軸方向に延在させて、正四角柱部材２０を回転ロール１６ａの左右の取付ロール１８、１８間に取り付けている。 Further, the adjacent outer faces 25a and 25b of the regular square column member 20 described above form an apex angle A (90 degrees) at one of the connecting portions of the regular square column member 20, as shown in FIGS. A mounting corner 26 is provided, and the mounting corner 26 extends in the axial direction, and the regular quadrangular prism member 20 is mounted between the left and right mounting rolls 18 and 18 of the rotary roll 16a.
一方、正四角柱部材２０に装着する加工金型２８は、所定の加工形状が施された加工面３０と、正多角柱部材２０の装着角部（外側面２５ａ、２５ｂ、頂角Ａ）２６と密接する装着部３２、及び加工面３０と装着部３２とを接続する接続面３４を軸方向に延在して形成している。また、この加工金型２８の装着部３２は、隣接する装着面３６ａ、３６ｂと、それらが形成する９０度の内角Ｂで構成され、その加工面３０は、その断面形状が取付ロール１８と同一曲率の円弧状面として形成されている。 On the other hand, the processing die 28 to be mounted on the regular square column member 20 includes a processing surface 30 having a predetermined processing shape, and mounting corners (outer surfaces 25a and 25b, apex angle A) 26 of the regular polygonal column member 20. A close mounting portion 32 and a connection surface 34 connecting the processing surface 30 and the mounting portion 32 are formed extending in the axial direction. Further, the mounting portion 32 of the processing mold 28 is configured by adjacent mounting surfaces 36a and 36b and an inner angle B of 90 degrees formed by them, and the processing surface 30 has the same cross-sectional shape as the mounting roll 18. It is formed as an arcuate surface of curvature.
そして、回転ロール１６ａの左右の取付ロール１８、１８間に取り付けた正四角柱部材２０への加工金型２８の装着は、前述した正四角柱部材２０の装着角部２６（外側面２５ａ、２５ｂ、頂角Ａ）に、加工金型２８の装着部３２（装着面３６ａ、３６ｂ、内角Ｂ）を密接させて行われる。
このように、正多角柱部材２０に加工金型２８を装着することにより、前記加工金型２８の加工中の移動が防止された回転ロールを備える加工装置とすることができる。
尚、図示した実施形態においては、加工金型２８を装着する正多角柱部材として、正四角柱部材２０（縦断面形状が実質上正方形）を用いたが、所望ならば正三角柱部材（縦断面形状が実質上正三角形）を用いても良い。しかしながら、この場合、前述した正多角柱部材の頂角Ａ、加工金型２８の内角Ｂが鋭角になり、回転成形加工中の加工応力が過度に加工金型２８装着部３２に集中して破損が生じ易く、このため、正四角柱部材とするのが好ましい。
Then, the mounting of the machining die 28 to the regular square column member 20 mounted between the left and right mounting rolls 18 of the rotating roll 16a is performed by the mounting corner portion 26 (outside surfaces 25a, 25b, tops) of the regular square column member 20 described above. This is performed by bringing the mounting portion 32 (mounting surfaces 36a, 36b, inner angle B) of the processing mold 28 into close contact with the corner A).
As described above, by attaching the machining die 28 to the regular polygonal column member 20, a machining apparatus including a rotating roll in which movement of the machining die 28 during machining can be prevented.
In the illustrated embodiment, the regular quadrangular prism member 20 (vertical cross-sectional shape is substantially square) is used as the regular polygonal column member to which the working mold 28 is mounted. However, if desired, a regular triangular prism member (vertical cross-sectional shape) May be a substantially equilateral triangle). However, in this case, the apex angle A of the regular polygonal column member and the inner angle B of the machining die 28 are acute angles, and the working stress during the rotational molding process is excessively concentrated on the working die 28 mounting portion 32 and is damaged. Therefore, it is preferable to use a regular quadrangular prism member.
本実施形態の回転ロールを備える加工装置による樹脂フィルム、中間パウチ等の被加工材の加工は、回転ロール１６ａ、１６ｂ間に、図２に示すように、例えば樹脂フィルムＦを搬送し、上側の回転ロール１６ａの正四角柱部材２０の装着角部２６に装着した加工金型２８の加工面３０と、下側の回転ロール１６ｂとのニップ力Ｎにより前述した立体成形を行う圧縮成形、フルカット加工、ハーフカット加工等が行われ、好ましくは冷間加工で行われる。加工金型２８による加工時には、取付ロール１８の左右の回転軸、正四角柱部材２０の装着角部２６の頂点、加工金型２８による加工部Ｃ、及び回転ロール１６ｂの回転軸が同一直線上に位置する。 Processing of a workpiece such as a resin film and an intermediate pouch by a processing apparatus including the rotating roll according to the present embodiment conveys, for example, the resin film F between the rotating rolls 16a and 16b as shown in FIG. Compression molding and full cut processing for performing the above-described three-dimensional molding by the nip force N between the processing surface 30 of the processing die 28 mounted on the mounting corner portion 26 of the regular square column member 20 of the rotating roll 16a and the lower rotating roll 16b. , Half cut processing or the like is performed, and preferably cold processing is performed. At the time of machining by the machining die 28, the left and right rotation axes of the mounting roll 18, the apex of the mounting corner portion 26 of the regular square column member 20, the machining portion C by the machining die 28, and the rotation axis of the rotation roll 16b are on the same straight line. To position.
そして、これらの加工においては、前述したように、上側の回転ロール１６ａに取り付けた正四角柱部材２０の装着角部２６に、加工金型２８の装着部３２を装着し、下側の回転ロール１６ｂとの間で行われることから、加工金型２８の加工部Ｃにおいては、図３に示すように、上方へのニップ抗力Ｎを受ける。しかしながら、このニップ抗力Ｎは、正四角柱部材２０の装着角部２６の外側面２５ａ、加工金型２８の装着部３２の内側面３６ａに沿うニップ分力ｎａと、正四角柱部材２０の装着角部２６の外側面２５ｂ、加工金型２８の装着部３２の内側面３６ｂに沿うニップ分力ｎｂとに分力されて軽減される。この結果、加工中の加工金型２８の移動が防止され、被加工材に適正な加工力が付与されることになる。
また、被加工材に対する加工金型２８の調整（最適クリアランス）も、正四角柱部材２０の装着角部２６の外側面２５ａ、２５ｂと、加工金型２８の装着部３２の内側面３６ａ、３６ｂで調整することにより、容易に行うことができる。
In these processes, as described above, the mounting portion 32 of the processing die 28 is mounted on the mounting corner portion 26 of the regular quadratic prism member 20 attached to the upper rotating roll 16a, and the lower rotating roll 16b. 3, the processed portion C of the processing mold 28 receives an upward nip drag N as shown in FIG. 3. However, the nip drag N includes the nip component na along the outer side surface 25a of the mounting corner portion 26 of the regular square column member 20 and the inner side surface 36a of the mounting portion 32 of the processing mold 28, and the mounting corner portion of the regular square column member 20. 26 and the nip component force nb along the inner side surface 36b of the mounting portion 32 of the machining die 28 is reduced. As a result, movement of the machining die 28 during machining is prevented, and an appropriate machining force is applied to the workpiece.
Further, adjustment (optimum clearance) of the machining die 28 with respect to the workpiece is also performed on the outer side surfaces 25a and 25b of the mounting corner portion 26 of the regular quadratic prism member 20 and the inner side surfaces 36a and 36b of the mounting portion 32 of the processing die 28. It can be easily performed by adjusting.
