を向上させることを目的とする。[Detailed Description of the Invention] The present invention relates to a winding device for long sheets (e.g., microfilm, movie film, magnetic tape, etc.), and in particular, winds a rolled sheet around a take-up reel shaft. The purpose is to improve the stability and reliability of winding when attaching.

ルムをリール8に巻取るものである。 First, a microfilm reader illustrated in FIG. 1 will be described as an example of a sheet winding device to which the present invention is applied. The tip of the microfilm F wound in a roll on a reel in the cartridge 1 is sent out by a capstan roller 2 driven by a motor 3, and wound onto the core 81 of a take-up reel 8 which is being driven and rotated by a motor 7 . In response to the winding completion detection signal, the capstan roller 2 is moved back from the film surface by a solenoid mechanism 5 or the like, and its drive motor 3 is stopped, and thereafter the film is wound onto the reel 8 by the winding motor. be.

圧力Pで押圧させている。 In the above configuration, the means shown in FIG. 2 is used to wind the leading end of the microfilm F fed from the cartridge 1 around the take-up reel core 81 . That is, a plurality of pressing rollers 9 1 to 9 3 are supported by arc-shaped guide plates 10 and arranged at approximately equal intervals around the outer periphery of the reel core 8 1 . Guide plate 10
is rotatable around the shaft 11 and always has a spring 12.
This causes the pressing rollers 9 1 to 9 3 to press the film F with a pressing force P.

点があつた。 Here, the leading edge of the film F is fed from the guide roller 62 to the reel 8, and in the case shown in the figure, after passing through three arc-shaped guide plates 10 and pressing rollers 91 to 93 , it goes around the take-up reel core 81 once. When the film F forms a loop, it overcomes the pressing force P of the pressure roller due to the hardness and curling of the film type, and forms a loop on the circumferential surface of the reel core 81 .
The inner circumferential surface F 1 of F 1 does not contact, and as a result
The drawback was that winding was difficult due to the frictional force of 1.F 1 .

もので、前記押圧ローラ91〜93の少なくとも1

る。 The present invention eliminates the drawbacks of the conventional example and provides an adjustable winding device so that the film can be wound around the take-up reel in a stable manner regardless of the type of film (sheet). At least one of the pressing rollers 9 1 to 9 3
The gist is that the two pressing forces P can be adjusted.

This shows an embodiment in which the pressing force of the th pressing roller 9c is adjusted.
The stopper 13 at one end of the spring 12 3 , which applies a pressing force through the spring 12 3 This is to adjust the pressing force P3 on the take-up reel core 81 .

b図)。 Now, the pressing force P3 of the third pressing roller 93 is the pressing force P1 and P2 of the first and second pressing rollers 91 and 92 .
Adjust the tension of the spring 12 3 so that it becomes larger. In other words, the pressing force P3 of the pressing roller through which the leading edge of the film F passes last is set to be the largest. When the leading edge of the film F passes between the pressure roller 9 1 and the take-up reel core 8 1 ,
Depending on the hardness and curl state of the film F, the pressure roller P1 is slightly rotated about the fulcrum 11 in the direction away from the take-up reel core 81 (No. 3a).

のように巻付きを完了するものである。 Next, the tip of the film F is placed on the third pressing roller 9.
3 and the take-up reel core 81 . However, since the pressing force P 3 of the pressing roller 9 3 is greater than the pressing force of the other pressing rollers, the above-mentioned degree of separation is small, and the leading end of the film F is brought into contact with the take-up reel core 8 1 and held there. Therefore, the leading edge of the film continues to move forward due to the frictional force with the rotating take-up reel core 81 , and is sandwiched between the loop-shaped film and the take-up reel 1 (Fig. 3c), and gradually becomes a loop as the take-up reel rotates. becomes smaller and the winding is completed as shown in Fig. 3d.

の調整方法を用いることができる。 Note that the number of pressing rollers is not limited to three as shown in the illustrated example. Further, the magnitude of the pressing force can be distributed such that, for example, the second to last pressing roller is at its maximum. Although the coil spring 12 was used to obtain the pressing force, a torsion spring or a plate spring may also be used. Further, the tension of the spring can be adjusted by adjusting the support fitting 13 by moving it forward or backward using an elongated mounting hole or an eccentric cam.

影響されることのない効果がある。 Since the present invention has the above-mentioned configuration, it is possible to always ensure smooth operation by adjusting the pressing force of at least one pressing roller on the take-up reel core according to the type of the target sheet, that is, its hardness and curl state. The starting end of the sheet can be wound around the take-up reel. In addition, there is an effect that it is not affected by variations in the pressing force of the pressing roller.
