It is a method of winding on the spool.

[0003]

[Problems to be Solved by the Invention]

(A) In the method disclosed in Japanese Patent Laid-Open No. 52-115215, two winding heads are structurally complicated, and the locking and primary winding are the same station and the cycle time is not shortened. Further, the film chute between the standard length and the primary winding is long, and the equipment becomes large. Further, when the short film is processed, it is conveyed by the feed roller, so that it is easy to cause quality problems such as scratches (due to an extra feed roller).

(B) In the method disclosed in JP-A-58-107528, the number of jigs for holding the film and the spool in a predetermined positional relationship is increased. In addition, the film has a long dimension so that films of each size can be processed, and a plurality of chutes are used, which causes scratches and clogging.

(C) In the method disclosed in Japanese Patent Laid-Open No. 01-043986, since the process of cutting the measuring length (regular length) of the specified length and the process of locking the take-up spool are in the same tact, the method is the same as that of (A). Cycle time does not shorten. Further, in high-speed operation, it becomes difficult to control the interference between the webs (loop and winding web), which may cause a quality problem.

1 and 2 are schematic front views showing an apparatus for winding and packaging a photographic film as a belt-shaped material winding and packaging apparatus of the present invention. FIG. 3 (a),
FIG. 4 is a schematic front view showing a box for storing a band-shaped material of the present invention as an intermediate means used in the band-shaped material winding and packaging apparatus. 3 (b) is a schematic side sectional view of FIG. 3 (a). The one shown in Fig. 1 is a strip-shaped material (photographic film) that is conveyed from right to left with the emulsion side down.
This is a system in which the index table as a base that rotates in the same plane is also moved in the counterclockwise direction after it is stored in the box for storing strips in the counterclockwise direction, and the one shown in FIG. In this system, the moving direction is clockwise and the emulsion surface is on the upper side.

In the present embodiment, a photographic film (hereinafter sometimes simply referred to as a film) is used as the belt-shaped material, but the material is not limited to this.

In FIGS. 1 and 2, the lengthwise film 2 pulled out from the film original winding supply unit (not shown) is used as a tension adjusting device for the lengthwise roller 23 which may be in the form of a sprocket roller, a suction roller, a rubber roller or the like. Will be supplied via.

The long film 2 may be perforated and latent image baked at a predetermined position at the time of film original winding, or may be perforated and latent image baked between the original winding supply unit and the fixed length roller 23. It may be crowded.

The fixed length roller 23 feeds the long film 2 at a rotation amount according to a predetermined cutting length and feeds it to the feed roller 24. The feed roller 24 feeds the film fed from the standard length roller 23 to the insertion / ejection roller 28 through the upper and lower blades of the cutter mechanism 22. The insertion / ejection roller 2
8 is installed in the band-shaped box 40, and the film 2 is inserted into the band-shaped passage 48 by the insertion / ejection roller and is stored in the band-shaped wound storage section 49.

The cutter mechanism 22 cuts the long film 2 into a predetermined length according to the rotation amount of the fixed length roller 23.

The cutting blade 22A of the cutter mechanism 22 is shown in FIG.
A hook 13 provided in the slit 12 of the spool 11 for film winding shown in the perspective view of FIG. 8 has a shape like the contour line 22B of the cutting waste shown in the plan views of FIGS. It is possible to punch out the locking hole 3 that is locked to. Further, a stripper is built in although not shown so that the cut film 2 can be easily removed from the blade.

In particular, in the conventional winding method, since there is no portion where the film conveying direction is reversed, the punching shape has the locking end 15 from the upstream side to the downstream side in the film conveying direction as shown in FIG. 7B. , In the order of the anti-locking end 16,
In the present invention, this order is reversed as shown in FIG. 7 (a), so the shape of the cutting blade 22A corresponds to this.

The insertion / ejection roller 28 is a fixed length roller 23.
Then, the film 2 sent from the feed roller 24 is sent to the band-shaped winding storage section 49 through the straight band-shaped material passage 48 of the band-shaped material storage box 40. It is desirable that the driving of the fixed length roller 23 and the insertion / ejection roller 28 are driven in synchronization with a timing belt or the like. In addition, the insertion / ejection roller 2
Since 8 is installed in the box 40 for storing strips,
Since the position of the insertion / ejection roller 28 moves, when the box 40 for storing the strip-shaped object comes to the film insertion position on the index table 50, the insertion / ejection roller is attached to the drive shaft synchronized with the standard length roller 23 by means of a friction wheel or the like. The structure is such that the drive is transmitted to the rotating shaft of 28. In particular, by setting the feed amount of the insertion / ejection roller 28 to be slightly larger than the feed amount of the standard length roller 23, it is possible to suppress the scratches and the jam of the transport due to the slack of the film 2 in the cutter mechanism 22. It is desirable that the film emulsion surface is fed to the box-shaped object storage box 40 in consideration of scratches on the film 2, friction coefficient with the sliding surface, film bending property, and the like. Therefore, in FIG. 1, the emulsion side of the film is conveyed to the lower side and in FIG. 2 to the upper side.

This band-shaped object storage box 40 is shown in FIG.
As shown in FIG. 4 , plate-shaped members 41 on both sides connected by stays 41S having a spacing S slightly wider than the film width W, and a side edge portion of the film in a cylindrical shape inside the plate-shaped members 41. The slide guide surfaces 41A and 41G for guiding the sheet are provided to form a strip winding storage portion 49 and a straight strip passage 48, and the passage 48 further has a film insertion / ejection / holding function. 28 and its pressing roller 2
8A, a nip mechanism 44 having a film holding function is provided for the pair of rollers or the insertion / ejection roller 28, and a fluid ejecting means is provided on the inner winding side of the film in which the film is wound to have an air layer between the films. The air supply nozzle 46 is provided. An air hole 42 is provided at the center of one of the plate-like members 41 on both sides.

The box 40 for accommodating the band-shaped material is a rotary moving means (hereinafter simply referred to as an index table) such as an index table 50 as a base which rotates in the same plane having a center of rotation on the same line as the film path line from the upstream side. 50) and a plurality of them are attached to the index table 50 at equally divided positions.

Outside the index table 50, in the counterclockwise direction in FIG. 1 and in the clockwise direction in FIG. 2, an insertion station and a film edge positioning station (which may also function as a reject station),
Four stations, that is, a locking station and a film feeding station for winding the film, are provided at equal intervals corresponding to each box 40 for storing the band-shaped material.

Here, in the case of the belt-shaped object storage box 40 in which the insertion / ejection roller 28 is not incorporated at least as a role of the insertion roller in the belt-shaped object storage box 40 and which does not have a film insertion / ejection function, FIG. , A roller 28R as a mechanism for independently providing a film insertion function at each station position corresponding to the box entrance / exit, as shown in the schematic front view of the winding and packaging apparatus shown in FIG. A roller pair including a pressing roller, a roller 28S as a film edge positioning and rejecting mechanism and a roller pair including the pressing roller, and a roller 28F serving as a feeding mechanism for locking the film edge and a roller pair including the pressing roller are provided. FIG. 5 corresponds to FIG. 1 and FIG. 6 corresponds to FIG. 2 in the relationship of the upper and lower sides of the emulsion surface of the film.

However, also at this time, the insertion / extraction roller 28 of the box 40 for storing the band-shaped material and the pressing roller 28 thereof.
It is advantageous to set A as a free roller pair for smooth insertion / extraction of the strip.

Further, the film is the slide guide surface 41A.
While being stored in a scroll-like shape in the strip-shaped material winding storage portion 49 along the line, the strip-shaped material passage box 48 near the entrance portion of the strip-shaped material storage box 40 is provided in order to reduce the contact resistance between the films. The air supply nozzle 46 is installed as described above. The supply pipe to the air supply nozzle 46 is laid from the center of rotation of the index table 50 to each air supply nozzle via a switching valve.

This is because when the contact resistance between the films is large, the film insertion resistance becomes large, and when the film is put into the box 40 for storing the band-like object, the film buckles or the film 2 is damaged. This is to eliminate the problem of.

That is, in order to form an air layer between films when the film 2 is accommodated in a scroll shape while following the slide guide surface 41A, an air supply nozzle is provided at a film insertion line (tangential portion) of the film scroll. A fluid such as air is jetted to the inner winding side of the film through 46, so that the film is smoothly wound.

Further, in order to reduce the contact resistance between the film and the sliding guide surface 41A, one means for providing an air layer therebetween is from the outside of the belt-shaped article storage box 40 to the inside wall of the plate-shaped member 41. It is desirable to install a nozzle that allows air to flow in along.

If these air pressures are too high, the film 2
The contact resistance between the slide guide surface 41A and the sliding guide surface 41A becomes large, and if it is too weak, the contact resistance between the films becomes large.

When the strip is a photographic film, the portion 48A on the emulsion side of the film which is continuous with the strip winding accommodating portion 49 of the strip passage 48 does not damage the emulsion surface of the film. Smooth chamfering is desirable. Further, for the same purpose, it is desirable that the portion 48A is provided with a roller such as a ball bearing at a right angle to the film transport direction.

The box 4 for storing the belt-like material by the standard length roller 23.
The film 2 sent toward 0 has a film end portion remaining from the cutting blade to the insertion / ejection roller 28 of the box 40 for storing the band-shaped object after the standard length cutting. Desirably, the film end portion is pulled out from the fixed-length cutter mechanism 22 by moving the belt-shaped object storage box 40 by the index table 50.

According to the conventional method, the film end portion is pulled out from the blade surface of the cutter mechanism 22 by a drawing roller having a complicated driving mechanism after the regular length cutting, but the drawing length is long and the film is easily scratched. It is also not desirable from the viewpoint of cycle time.

Further, in order to widen the allowable value of the control range of the air pressure, in the present embodiment, the air hole 42 formed in any one of the plate-like members 41 on both sides of the belt-like object storage box 40. A smooth winding is obtained by letting air escape from the inside.

An external discharge mechanism (rejector) for removing a defective portion (for example, a film joining portion) in the long film 2 to the outside of the system may be installed immediately after the cutter mechanism 22, but it is preferable. As described above, it is preferable that the outside ejection mechanism (rejector) also serves as the insertion / ejection roller 28 or the independent positioning-dedicated independent roller 28S which is the film end positioning mechanism of the belt-shaped object storage box 40.

In the conventional method, it is necessary to synchronize the film feeding of the standard length with the feeding, the withdrawal from the cutter mechanism 22 and the ejecting from the system (reject), and the secondary feeding of the film after the regular length cutting. Since a drive system separate from the standard length is required, the drive system is complicated and an inertial load is applied to the drive system of the standard length roller 23, which impedes speeding up of conveyance.

When adopting the method of pulling out the film from the cutter at the end of the film without carrying out the secondary feeding, the length of the remaining end is made as short as possible in order not to scratch the film. There is a need. Therefore, it is disadvantageous to have the external discharge mechanism or the like in the middle as in the prior art. Therefore, the external discharge mechanism is one of the work stations when the index table 50 on which the box 40 for storing belt-shaped objects is mounted is stopped (here, It is desirable to take it to the next positioning station).

However, when the film is pulled out from the cutter mechanism 22 at the end of the film by the secondary feeding, the next station of the index table 50 is as described above.
Although it may be dedicated to the outside of the system, when the film edge is pulled out from the cutter mechanism 22 by moving the index table 50 without secondary feeding, it is preferable to position the length of the film edge at the next station.

More specifically, at the next positioning station, the film end portion which extends from the box 40 for accommodating the strip-shaped material is provided in the box 40.
And pull it in. If the box 40 is not provided with the insertion / ejection roller 28, a positioning roller 28S provided separately at a positioning station outside the box 40 is rotated to feed a predetermined amount of film into the box 40 and the film locking end 4 Can be positioned.

Since the amount of film pulled out from the cutter mechanism 22 is almost the same every time, the film may be fed at a predetermined number of revolutions, but the perforation of the film, the notch of the edge, or the end may be detected to stop the feeding. Since the detection sensor is installed, the film edge can be accurately positioned.

By positioning the film end portion at this station, the locking operation can be ensured at the next station and the tact can be shortened by dividing the work.

That is, at the next locking station after positioning, the film end is locked to the spool.

For locking, the openable and closable locking guide 87, which is schematically shown and installed between the belt-shaped object storage box 40 and the spool 11, is closed and the insertion / ejection roller 28 is moved by a predetermined amount. The film 2 is rotated and sent out from the box 40 for storing the band-like material, and the film locking end 4 is moved to the spool 1.
It is inserted into the slit 12 of No. 1 and is hooked by hooking the locking hole 3 of the film locking end 4 to the hook 13.

The spool 11 is equidistantly arranged on a spool index table 80 having a center of rotation on the same line as the center of rotation of the index line 50 on which the pass line in the cutter mechanism 22 of the film 2 and the box 40 for storing the band-shaped material are mounted. Spool holder 8 arranged and provided in
It is held at 2. Outside the index table 80, the spool 11 is supplied, the orientation for determining the position of the slit 12, the locking, the winding,
Stations that perform functions such as taking out scrolls are arranged in this order.

Although an example of a non-adhesive paper locking type spool has been described here, the same process, from the standard length to the winding process, is also performed when locking the spool using an adhesive tape. It can be done effectively.

Although the example of the 135 film has been described here, the same process from standard length to winding can be effectively performed also in another form such as 110, 120, APS and the like. Further, it is also applicable to strips such as magnetic tapes other than photographic film.

When the insertion / ejection roller 28 is not installed in the belt-shaped object storage box 40, the locking guide 87 is used similarly to the roller pair of the insertion exclusive roller 28R of the insertion station and the roller pair of the positioning roller 28S of the positioning station. A pair of lock-dedicated feeding rollers 28F is incorporated in the structure. The roller pair of the delivery roller 28F is driven by a dedicated drive motor, and in the case of the insertion / removal roller 28 incorporated in the box 40,
Similar to the positioning station, a means for transmitting power from another drive motor to the rotary shaft via a friction wheel or the like is adopted.

Like the positioning station, the feed amount may be a predetermined amount, but a means for stopping the feed by detecting the film edge or the like or stopping the feed after a predetermined time can be adopted.

In this case, it is desirable to set the insertion torque within a predetermined value so that the film will not buckle.

In the unlikely event that locking is not possible for some reason, by interlocking the fixed length feeding in the previous step and moving it to the outside system discharge station which is also used by the positioning station, and taking it out of the system, The device can be stopped to minimize defects.

Go to the next station, film 2
Spool 1 by pulling out the box 40
Take up to 1.

At this time, a sealing mechanism 42A having a structure for closing air so as not to leak from the air hole 42 in the plate-like member 41 on the side surface of the band-shaped object storage box 40 is installed at this station. This is because the scroll diameter of the film 2 in the strip-shaped object storage box 40 becomes small at the time of unwinding and the film 2 is not damaged at the outlet of the cylindrical container.

The air hole 42 and the structure for closing the hole 42 may be incorporated in the box 40 for accommodating the band-shaped material in addition to the separate structure as described above.

A free roller 43A is arranged at a portion where the film 2 comes out of the box 40 for accommodating the belt-like material, and the end portion of the film 2 can be regulated by changing the moving direction of the film at the film exit.

A fixed tilt guide 8 is provided between the station for winding the index table 50 having the box 40 for storing the belt-like material and the spool 11 on the spool holder 82 of the spool index table 80.
5 is installed, and the film 2 unwound from the band-shaped object storage box 40 moves along this tilt guide 85 and is wound up. The tilt guide 85 is opened on the film side so that the locked film 2 does not interfere with the movement of the locked film 2 (when the cross section of the tilt guide is U, air regulation type).
However, an opening / closing structure may be used.

[0065]

As described above, according to the present invention, the front end of the band-shaped material is cut into a predetermined length while the front end of the band-shaped material is inserted into the box for storing the band-shaped material and is sent. Is pulled out and locked to the take-up spool via the locking means, and is taken up on the take-up spool while pulling out the band-shaped article from the box for storing the band-shaped article. Not only can the cycle time be shortened because the processes can be separated and processed in parallel, but the reject mechanism for defective films (external discharge mechanism) can be performed at a different station, which can greatly simplify the mechanism and greatly reduce costs. Furthermore, since the inertial load of the standard length system can be reduced, the standard length error due to the slip of the film is eliminated, and various excellent effects such as quality improvement / stability, equipment stability / production speed improvement can be obtained.
