装置に関するものである。Detailed Description of the Invention 3. Detailed Description of the Invention (Industrial Field of Application) The present invention is a method for automatically manufacturing a strip of film, etc. applied to, for example, a biaxially stretched film manufacturing device, a non-stretched film manufacturing device, etc. The present invention relates to an automatic cutting and winding device for cutting and rewinding strips of film and the like, which can be used for winding paper, cloth, etc.

のの開発が強く望まれていた。(Prior art) When winding a strip-like material such as a film (hereinafter referred to as film), there is a method in which the core is wound directly onto the core without using adhesive tape or other adhesive (hereinafter referred to as tapeless winding). ) is attracting attention in many fields because it does not damage the mill roll inner layer film due to unevenness on the core surface caused by adhesive tape, etc., and there is no need to remove residual adhesive when reusing the core. However, there are problems such as scratches on the cut edges of the film, so there has been a strong desire to develop something more perfect.
以下従来のテープレス巻取機について概要を第８図〜第

フィルム巻取側に枢支されている。The outline of the conventional tapeless winding machine will be explained below with reference to Figs. 8 to 10. 1 indicates a film, 2 indicates a core, and the core 2 is rotated in the direction of arrow A in the figure by a drive device (not shown) on a turret 4. It is equipped to do so. 3 is a guide roll, which connects the cores 2 and 9 of the turret 4.
It is rotatably supported by the ends of arms 4a that are spaced apart by 0°. 5 is also a guide roll, but this guide roll 5 is pivotally supported by the film 1 supplying end of the frame 10, and also crosses the intermediate part between the guide roll 5 and the core 2 and turns in the direction B in the figure. A take-up roll 6 is provided, and the roll 6 is pivotally supported at the tip of a swinging arm 7, and the other end of the swinging arm 7 is pivotally supported on the film winding side of the frame 10. .
そして前記巻込みロール６は、前述の通りガイドロール
５とコア２の中間部を横切って旋回し、コア２の後部側
まで到るようになっている。As described above, the winding roll 6 turns across the intermediate portion between the guide roll 5 and the core 2, and reaches the rear side of the core 2.
８はカッタで、他端を同じくフレーム１０の適所に枢着
されたアーム９の先端部に装着され、同アーム９は図示

を切断するようになっている。Reference numeral 8 designates a cutter, the other end of which is attached to the tip of an arm 9 which is also pivoted at a suitable position on the frame 10, and the arm 9 is swung in synchronization with the rotation of the winding roll 6 by a drive device (not shown). , the cutter 8 at the tip of the film 1
It is designed to cut.
さて第８図に於いて、フィルム１はクーレット４の他端

ア２を抱き込み、第９図の状態となる。Now, in FIG. 8, the film 1 is wound around a core (not shown) attached to the other end of the coolet 4.
When the mill roll wound on the same core reaches full capacity,
The winding roll 6 turns in the direction of arrow B, and the film 1 wraps around the core 2, resulting in the state shown in FIG.
次に第１０図の如くカッタ８を下降させ、フィルムｌを
切断すると共に、フィルム端ａをコア２と巻込みロール
６の間のｂ部へ押し込み、巻付けを終了する。Next, as shown in FIG. 10, the cutter 8 is lowered to cut the film 1, and the end a of the film is pushed into the part b between the core 2 and the winding roll 6 to complete the winding.
しかしながら前記従来の場合は、このように新しいコア

破断や、蛇行、シワ等の発生を防ごうとする為、時間を
かけて徐々にロール６を移動させる必要があった。However, in the conventional case, in order to wind up the cut film end a when rewinding to a new core, it is necessary to wrap the core 2 with the film 1 as shown in FIG. However, the film 1 has a certain tension generated between the winding roll 6 and the guide roll 3 in FIG. 8 due to winding, and the film 1 is brought from the state shown in FIG. 8 to the state shown in FIG. 9. , apply excessive force to film 1,
In order to prevent breakage, meandering, wrinkles, etc., it was necessary to gradually move the roll 6 over time.
しかるにコア２の表面は平滑ロールの如く平滑でなく、
且つコア２の表面速度は巻付は直後のフィルムのたるみ

ア２によって擦過された部分は、製品として扱うことが
出来ず、しかもこのロス分はフィルム速度が高くなる程
多くなる欠点があった。However, the surface of the core 2 is not smooth like a smooth roll;
In addition, the surface speed of core 2 is set slightly faster than the film speed to prevent the film from sagging immediately after winding, so slippage occurs between film 1 and core 2, causing scratches on film 1. There was a risk that this would happen. Therefore, the portion rubbed by the core 2 cannot be treated as a product, and this loss increases as the film speed increases.
さて第１０図に示すように、フィルム１はコア２、ガイ

刃状を使用している。Now, as shown in FIG. 10, the film 1 is supported by the core 2 and the guide roll 3, the arm 9 descends, and the cutter 8 enters and cuts the film 1 as described above. Note that the cutter 8 normally has a saw blade shape as shown in FIGS. 11 and 12.

のくせのついた不良フィルムを長くする欠点があった。In the conventional film winding machine shown in FIG. 8, in order to obtain a good cut surface of the film material, the cutter must have good sharpness, and the faster the film travels, the faster the operating speed of the cutter 8. When cutting, it is necessary to take measures such as increasing the tension of the film or providing a means to support the film to prevent the film from being pushed by the cutter, but if these measures are not met. As shown in FIG. 13, a strip-shaped uncut portion is generated at the cut portion 9, and when the core is wound around a new core, each strip-shaped portion of the cut portion 9 is bent or overlapped, resulting in unevenness. When the unevenness wraps around the upper layer of the wire, the film 1 becomes uneven, and the flatness of the rewound film 1 becomes F, resulting in the occurrence of many defective parts. The length β of the cut portion is determined by increasing the running speed of the film 1 and the lower the cutter operation speed, the longer the culm has less tension on the film (this has the drawback of lengthening a defective film with irregularities).

なる。(Effects of the Invention) As described in detail above, according to the present invention, by applying an electric charge to the film or core surface at the same time as cutting the film, the film can be adsorbed to the core and wound, so tapeless winding can be performed. There is no need to enclose the core with the film before cutting, and there is no need to wrap the core with the film at the end of mill roll winding, which eliminates the loss of film due to abrasion due to contact with the core at the end of winding, and greatly improves film yield. A pair of presser members that press against the cutter and a cutter that presses against the film to cut it are placed facing each other with the film in between, so the pair of presser members increases the tension of the film during cutting. The upper pair of holding members press the film so that it does not easily escape from the cutter, and the cutter is equipped with a heater and is heated above the melting point of the film, so the film can be instantly melted and cut into a continuous half-moon shape. Therefore, the cut end of the film will have a shape as shown in Figure 7, and the length of the cut portion will be as shown in Figure 7. , becomes negligibly short and can be formed into a stable and good shape. This has the effect of significantly reducing the number of defective parts of the film when the film is rewound onto a mill roll and used again. The above effects become more pronounced as the cutting and winding speed increases.
