Abstract

PURPOSE:To enable positive winding by disposing a face formed by the axial center of a take-up reel and a carrier face by a carrier roller in such a way as not to be vertical so as to restrain the end part of a long-sized object from being brought into contact with and caught by a reel protrusion. CONSTITUTION:A carrier roller shaft 12 and a take-up reel shaft 7 are disposed not in the parallel state but in the torsional relation by an angle alpha. A flexible joint is interposed between a motor shaft and the roller shaft because of their unparallel disposition. The width direction cross section of a film F started to be wound on a reel 3 from a carrier roller 1 is placed in the inclined state in relation to the reel 3 as the distance from a reel core 6 is enlarged, and the width C of the film F is narrowed as indicated by C' with the increase of the distance from the core 6. The film F is not therefore easily caught by the protrusion 3b of the reel 3 with the increase of its distance from the core 6. The film F can be therefore taken up by stable rotation and also is prevented from being damaged.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a long object winding device for automatically winding up a long object, such as an O-roll film.

<Prior art> Conventionally, a long object winding device that automatically winds a long object is
For example, it is used in devices that record images on long microfilm, automatic developing devices that automatically develop exposed microfilm, and search devices that search for each film frame recorded on microfilm. This was devised in order to save the operator's effort, shorten the operation time, and improve the operability. FIGS. 5 and 6 show an example of this type of long object winding device.

That is, in FIG. 5, the leading end of the long microfilm F is guided by an unillustrated film guide so that the center line of the film F is on the plane formed by the axial center of the take-up reel 3. The paper is transported in the direction of arrow a by the transport O-rollers 1 and 1' driven by the motor M via the transport roller shaft 12 integrated with the motor shaft, and by the guide arm 2 disposed adjacent to the transport roller 1. It is designed to be guided to the take-up reel 3. Further, the guide arm 2 has one end rotatably supported by a shaft 2a and is biased clockwise (toward the take-up reel 3) by a spring 4, and a guide roller 5 is rotatably supported at the other end. , the guide arm 05 is pressed against the core 6 of the take-up reel 3, and the guide arm 2
has a gentle arc shape from the conveyance roller 1 toward the guide roller 5, and this arc-shaped portion guides the leading edge of the film F to the guide roller 5 and the core 6.

The take-up shaft 7, which vertically supports the take-up reel 3 and is arranged parallel to the transport roller shaft 12, has a circumferential speed of the core 6 of the take-up reel 3 that is higher than the circumferential speed of the transport roller 1. In order to increase the speed, driving is obtained from the motor M together with the conveying roller 1. However, as a transmission means, the take-up reel 3 is transmitted by utilizing the friction between the pulley 8 provided on the take-up shaft 7, the pulley 9 provided on the conveyance roller shaft 12, and the belt 10 placed on the pulley 8.9. When a load exceeding a predetermined value is applied, slippage occurs between the pulley 8.9 and the belt 10, and the take-up reel 3 that receives such rotation transfers the film F with a predetermined torque. Can be rolled up. Further, an encoder 11 provided on the winding shaft 7 is connected to a control 11 circuit (not shown) to detect the amount of rotation, and when the film F is wound around the winding reel 3, the winding reel 3 Since it rotates at the same circumferential speed as the conveyance speed of the film F at the winding diameter of There is.

Furthermore, the take-up reel 3 is as shown in FIGS.
As shown in the figure, both ends of a cylindrical core 6 around which a rubber ring 6a is wound are sandwiched between two disc-shaped side plates 3a, and a protrusion 3b is integrally provided in the center hole of the side plates 3a. The width B of the two side plates 3a other than the protrusions 3b is the same as the width C of the film F, or is slightly wider, but the width of the protrusions 3b increases as the distance from the rotation axis of the take-up reel 3 increases from the width near the core 6. It spreads in a tapered shape and has a width B. Although the shortest width of the protrusion 3b is narrower than the width C of the film F, it can be expanded to the film width C by elastic deformation.

When the leading end of the film F is guided by the guide arm 2 to such a take-up reel 3 and pressed against the core 6 by the guide roller 5, the leading end of the film F spreads out the protrusion 3b of the take-up reel 3. The film F, which is sandwiched between the protrusion 3b and the core 6, is pulled by friction with the rubber ring 6a, rotates together with the take-up reel 3, and is wound up.

<Problems to be Solved by the Invention> However, although the width of the protrusion 3b increases in a tapered manner in the conventional example described above, even a small force can cause the take-up reel 3 to move as it moves away from the rotation axis of the take-up reel 3. As a result, the edge of the film F in the width direction gets caught on the protrusion 3b, resulting in the film F not being wound in the shortest distance from the transport roller 1 to the core 6, as shown in FIG. Storing often occurs. As a result, not only is it impossible to successfully wind the film F without any gaps, but also the rotation of the winding shaft 7 becomes unstable, making winding detection and winding amount detection inaccurate.
Furthermore, there is a risk that the film F may be scratched by being pressed against the guide arm 2 and being rubbed.

SUMMARY OF THE INVENTION In view of the problems of the prior art described above, it is an object of the present invention to provide a method for winding up a long object such as a film, in which the long object can be reliably wound up without causing any damage to the long object.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the present invention includes a take-up reel having a displaceable protrusion on a side plate, and a conveying means for conveying a long object to the take-up reel. The long object winding device is arranged so that the plane formed by the axial center of the take-up reel and the surface of the long object conveyed by the conveyance means are not perpendicular.

In the long object winding device with the above configuration, the long object is transported by the conveying means, and the width direction of the long object does not match the width direction of the take-up reel. It is possible to reduce the contact and catching of the end of the take-up reel with the projection of the take-up reel.

<Example> Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4. Note that the same parts as in the conventional example described above are given the same reference numerals, and the explanation thereof will be omitted, and only the different structures will be explained.

First, as shown in FIG. 3, the conveying roller shaft 12 and the winding shaft 7 are not parallel but twisted by an angle α, and the motor shaft 14 and the conveying roller shaft are parallel to the winding shaft 7. 12, the drive is transmitted by interposing a flexible joint 13 between the motor shaft 14 and the conveying roller shaft 12, as shown in FIG. The other configurations are the same as those of the conventional example described above.

In this embodiment with the above configuration, the leading end of the film F is guided by a film guide (not shown) so that the center line of the film F is aligned with the axial direction of the take-up reel 3, and the motor Motor shaft 14. The sheet is transported in the direction of arrow a by the driving transport roller 51 via the flexible joint 13 and the transport roller shaft 12, and guided to the take-up reel 3 by the guide arm 2 disposed adjacent to the transport roller 1.

Then, as shown in the cross-sectional view of FIG.
Since the winding shaft 7 and the winding shaft 7 are in a twisted relationship, the transport row 51
The cross section in the width direction of the film F wound around the take-up reel 3 is inclined obliquely with respect to the take-up reel 3 as it moves away from the core 6 of the take-up reel 3, and as it moves away from the transport roller 1, the inclination becomes α becomes. In other words, the film F wound around the take-up reel 3 from the transport roller 1 is twisted with respect to the take-up reel 3 as the distance from the core 6 increases, and the width of the film F in the axial direction of the take-up reel 3 is C.
As the distance from the core 6 increases, the width becomes narrower like C'. Therefore, during winding, the claw portion 3b at the widthwise end of the film F
Not only does the film F become less likely to be caught as it moves away from the core 6, but the leading edge of the film F is transferred to the take-up reel 3,
When the film F enters between the two side plates 3a, the leading end of the film F hits the outer periphery of the side plate 3a, and winding defects such as curling to the side can also be reduced.

As a result, the film F can be wound with stable rotation, so the encoder 11
Winding and winding position can be detected accurately in a short time.

<Effects of the Invention> As explained above, the present invention provides a long object winding device having a winding reel having a displaceable protrusion on the side plate, and a conveyance means for conveying the long object to the winding reel. In,
By arranging the take-up reel so that the plane formed by the axial center thereof is not perpendicular to the conveying surface of the long object by the conveying means, the long object can be reliably and orderly wound. Since it winds up with stable rotation, it has the effect of not damaging long objects.
