In this embodiment, a plurality of plates 1a having a predetermined thickness are superposed to form a unit with bolts and nuts 1b, and the length of the rectangular cylinder can be easily changed. As shown in FIG. 3, this mold 1 is cantilevered on its base end side, and a guide roller 1c pivotally supported on the base end side moves in a guide groove 2a of a guide member 2 erected on the base end side. By doing so, the rod 3a of the air cylinder 3 can be moved vertically up and down smoothly.
【００１０】 ４は前記型１の下方に配置される挟持プレートであり、その下方にガイドロッ ド４ａを突設し、このガイドロッド４ａとこれを内挿するガイド筒４ｂの作用に よって上下方向への移動が自在となされている。なお、この上下移動時、挟持プ レート４の型１に対する相対位置が変化しないように、ガイドロッド４ａにはキ ー４ａａを突設し、ガイド筒４ｂには図示省略したがこのキー４ａａに嵌合する キー溝を設けている。そして、この挟持プレート４は、スプリング５によって上 方に付勢され、常時は上方限位置にある前記型１の下面と若干の間隔を存した上 限位置で停止している。Reference numeral 4 denotes a sandwiching plate arranged below the mold 1. A guide rod 4a is provided below the sandwiching plate, and the guide rod 4a and a guide cylinder 4b into which the guide rod 4a is inserted vertically move in the vertical direction. Can be freely moved. A key 4aa is provided on the guide rod 4a so that the relative position of the clamping plate 4 with respect to the mold 1 does not change during this vertical movement, and the guide tube 4b is fitted to the key 4aa, though not shown in the drawing. There is a keyway to match. The holding plate 4 is biased upward by a spring 5 and is normally stopped at an upper limit position with a slight distance from the lower surface of the mold 1 which is at an upper limit position.
【００１１】 ６は上限位置で停止している挟持プレート４の若干下方位置において、型１の 両側にそれぞれ上下に２個ずつ対向状に配置された押圧ローラであり、これら相 対する押圧ローラ６はそれぞれが接離する方向に移動自在で、かつ常時は例えば コイルスプリング６ａによってお互いが接近する方向に付勢され、コイルスプリ ング６ａによって付勢されたこれら押圧ローラ６間の距離は型１の幅より若干短 く維持されている。Reference numeral 6 denotes a pressing roller, which is disposed at a position slightly below the sandwiching plate 4 stopped at the upper limit position so as to be opposed to each other on the upper and lower sides of the mold 1, and two pressing rollers 6 are provided. Each of them is movable in a direction in which they come into contact with and separate from each other, and is normally urged in a direction in which they approach each other, for example, by a coil spring 6a, and the distance between these pressing rollers 6 urged by the coil spring 6a is smaller than the width of the mold 1. It is maintained slightly short.
【００１２】 ７は前記上限位置にある型１の上方に配置された押さえ機構であり、エアーシ リンダ８のロッド８ａの出退動によって昇降動するようになっている。 この押さえ機構７は、型１の幅方向中央部に配置される主プレート７ａと、こ の主プレート７ａの両側に一対配置され、それぞれがスプリング７ｂによって下 方に付勢されて主プレート７ａとの相対高さ位置を変化自在に上下動する副プレ ート７ｃとで構成され、これら副プレート７ｃの一方を他方より上方に配置して 、紙の重合状態を特定できるようにしている。Reference numeral 7 denotes a pressing mechanism arranged above the mold 1 at the upper limit position, which is moved up and down by the rod 8a of the air cylinder 8 moving back and forth. The pressing mechanism 7 is provided with a main plate 7a arranged in the center of the mold 1 in the width direction and a pair of both sides of the main plate 7a. Each of the pressing mechanisms 7 is urged downward by a spring 7b to form a main plate 7a. And a sub-plate 7c which vertically moves its relative height position. One of these sub-plates 7c is arranged above the other so that the superposition state of the paper can be specified.
【００１３】 なお、これら副プレート７ｃは型１と略同じ長さを有しているので、その上下 動が円滑に行えるように２本のガイドロッド７ｄを連結板７ｅで接続している。 本実施例ではこの接続部においてスプリング７ｂを受け止め、副プレート７ｃを 下方に付勢するものを示している。Since the sub plates 7c have substantially the same length as the mold 1, two guide rods 7d are connected by a connecting plate 7e so that the sub plates 7c can be vertically moved smoothly. In this embodiment, the connection portion receives the spring 7b and urges the sub plate 7c downward.
【００１４】 ９は上限位置にある挟持プレート４と略同一平面上に配置された位置決め台で あり、角筒体となす所定寸法のシート状の紙Ａを位置決め載置するためのもので ある。Reference numeral 9 denotes a positioning table which is arranged substantially on the same plane as the sandwiching plate 4 at the upper limit position, and is used for positioning and placing the sheet-shaped paper A having a predetermined size and forming a rectangular tube.
【００１５】 本考案の角筒体の成形装置は上記したような構成であり、次にこの装置を用い て角筒体を成形する方法を説明する。 まず、所定寸法のシート状の紙Ａを上方限位置にある型１と挟持プレート４間 に配置する〔図６（ａ）参照〕。この時、型１と紙Ａとの相対位置は位置決め台 ９上に取り付けてある位置決め用プレートの位置を適宜設定することで決定され る。The device for forming a rectangular cylinder of the present invention has the above-described structure. Next, a method for forming a rectangular cylinder using this device will be described. First, a sheet-shaped paper A having a predetermined size is arranged between the mold 1 and the sandwiching plate 4 at the upper limit position (see FIG. 6A). At this time, the relative position between the mold 1 and the paper A is determined by appropriately setting the position of the positioning plate mounted on the positioning table 9.
【００１６】 次に、エアーシリンダ８のロッド８ａを出動作させて型１を下降させる。これ により、紙Ａは型１と挟持プレート４によって挟持された状態で下降する〔図６ （ｂ）参照〕。この下降に伴って、紙Ａは押圧ローラ６によって順次型１の側面 に沿って折り曲げられてゆき〔図６（ｃ）〕、最終的に紙Ａの両端部は内側に向 かって折り曲げられた状態となる。Next, the rod 8 a of the air cylinder 8 is moved out to lower the mold 1. As a result, the paper A descends while being held by the mold 1 and the holding plate 4 (see FIG. 6B). Along with this lowering, the paper A is sequentially bent along the side surface of the mold 1 by the pressing roller 6 [Fig. 6 (c)], and finally both ends of the paper A are bent inward. Becomes
【００１７】 前記エアーシリンダ８のロッド８ａの出動作と若干のタイムラグをもってエア ーシリンダ３のロッド３ａを出動作させて押さえ機構７を下降させ、前記内側に 向かって折り曲げられた紙Ａの両端部を型１に沿って押さえ付け、その一方の端 部に予め貼付された接着剤によって重合部を貼設し、角筒体Ｂに成形する。The rod 3a of the air cylinder 3 is moved out with a slight time lag from the movement of the rod 8a of the air cylinder 8 to lower the pressing mechanism 7, and the both ends of the paper A folded inward are moved. It is pressed along the mold 1, and a polymerized portion is attached to one end of the die with an adhesive that is attached in advance to form a rectangular tubular body B.
【００１８】 ところで、紙Ａの両端部を押さえ機構７によって押さえ付ける際、本考案では 、まず、図６の紙面右側に配置された副プレート７ｃが先に紙Ａの紙面右側の端 部を押圧して型１の上面に沿わせた後〔図６（ｄ）参照〕、紙面左側に配置され た副プレート７ｃで紙Ａの紙面左側の端部を押圧して型１の上面に沿わせ、この 端部の内側に予め貼付した接着剤によって紙Ａの紙面右側の端部外側に重合する 。そして、その後主プレート７ａによってその重合部を押さえて〔図３参照〕重 合部を貼設し、角筒体Ｂに成形する。By the way, when the both ends of the paper A are pressed by the pressing mechanism 7, in the present invention, first, the sub plate 7c arranged on the right side of the paper in FIG. 6 first presses the right end of the paper A on the paper. 6 and then along the upper surface of the mold 1 (see FIG. 6 (d)), the sub plate 7c arranged on the left side of the paper presses the end of the paper A on the left side of the paper to move along the upper surface of the mold 1, The adhesive is pre-applied to the inside of this end to superpose on the outside of the right end of the paper A in the drawing. Then, after that, the overlapping portion is pressed down by the main plate 7a [see FIG. 3], and the overlapping portion is pasted to form the rectangular tubular body B.
【００１９】 なお、本実施例では型１や押さえ機構７の昇降機構としてエアーシリンダを示 したが、これに限るものではなく、親ねじ送り機構、ラックとピニオンを用いた 歯車機構、カムを用いた往復機構等適宜の機構を採用してもよい。また、付勢機 構もスプリングに限らず、弾性ゴム等を採用してもよいことは言うまでもない。In this embodiment, the air cylinder is shown as the lifting mechanism of the mold 1 and the pressing mechanism 7, but the invention is not limited to this, and a lead screw feeding mechanism, a gear mechanism using a rack and a pinion, and a cam are used. An appropriate mechanism such as the reciprocating mechanism may be adopted. Needless to say, the biasing mechanism is not limited to the spring, and elastic rubber or the like may be adopted.
