Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a method of cutting a photographic film into a predetermined length, and locking the leading end of the photographic film on a spool, and winding the film, that is, a method of producing a film scroll. Related to the device.

[Conventional technology]

Conventionally, when creating a scroll of photographic film, to what has been known as a method and apparatus for winding the film,
For example, there is one described in JP-A-52-115215.
In the former, a fixed-length sprocket is rotated a predetermined time to send out a long film, a single film of a specified length is cut with a cutter, the leading end of the film is locked on a spool, the primary winding is performed, and the film transport path is opened. Drop the film,
This is an apparatus based on a method of winding to a predetermined accuracy in secondary winding.

[Problems to be solved by the invention]

However, the above-described apparatus and method disclosed in JP-A-52-115215 require two winding stations,
The structure is complicated, and the cycle time is not shortened because the locking of the spool and the primary winding are performed in the same station in a time series and vertically connected. Further, a maximum length of a fixed length (for example, a length of a 36-shot film) is required as a film transport chute between the fixed length sprocket and the primary winding, and the equipment is increased in size. Furthermore, when processing a short film, the film after the fixed length punching must be conveyed to a spool position by a feed roller, which tends to cause quality problems such as scratches.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is an overall schematic side view showing a method and apparatus for producing a film scroll according to a first example of the present invention.
FIG. 4 is a sectional view of a main part of the film transport, FIG. 4 (a) is a side view showing a spool orientation, and FIG. 4 (b) is a sectional view thereof. In the drawing, reference numeral 6 denotes a rail chute for supplying a spool, which is continuously arranged with the long boss short boss direction aligned in a certain direction. The shutters 7a and 7b alternately come and go, and the spools 17 are chucked one by one by the spool chuck 43 on the turret T. This spool supply chucking position is the first station (I).
Next, the turntable T rotates to the second station (II), and the spool 17 mounted at the first station engages with the servomotor 44 at the second station. The notch 17a engages with the orientation claw 42 to determine the direction of the slit 17 'of the spool 17, the turntable rotates, and the spool chuck 43 of the spool whose slit position is oriented is the second position. It will be located at three stations (III). At this time, of course, in the second station, the orientation of the spool supplied to the succeeding spool chuck is performed, and in the first station, the further subsequent spool is supplied to the spool chuck 43 and mounted.

Now, the function of the third station will be described. Reference numeral 11 denotes a fixed-length sprocket. The long-length film F drawn from a not-shown original magazine is supplied to the fixed-length sprocket 11 through a tension adjusting device. The fixed-length sprocket 11 feeds the film F at a number of revolutions corresponding to the cutting length and supplies the film F to the feed roller 12. The feed roller 12 is a film F sent from the fixed-size sprocket 11.
Is supplied to the extraction roller 14 through the space between the upper and lower blades of the cutter mechanism 13. The cutter mechanism 13 cuts the film F to a specified length in response to the rotation speed of the fixed-size sprocket 11. This cutting blade can simultaneously punch out a locking hole for locking the spool to a hook provided in the slit. The pull-out roller 14 guides the film F to the front insertion roller 16 through the guide rail 15.

As shown in FIG. 2, the guide rail 15 is formed at a distance slightly wider than the width of the film F with the pull-out roller 14 and the insertion roller.
16 and a pair of plate-like members 18a and 18b provided between them and film sliding surfaces 19a and 19b provided on the upper surface thereof in a hook shape on the inner surface. Nozzles 20a, 20b for jetting compressed air obliquely penetrating the wall surfaces of the plate-like members 18a, 18b so that both edges in the width direction of the film F slide on the sliding surfaces 19a, 19b.
b is arranged along the direction of travel of the film. These nozzles 20a, 20b are connected to a compressed air source (not shown) via air passages 22a, 22b in ducts 21a, 21b provided on the outer walls of the plate members 18a, 18b. Therefore, the film F is conveyed in a state where both edges in the width direction are pressed against the sliding surfaces 19a, 19b by the compressed air ejected from the nozzles 20a, 20b.

The insertion guide 25 of the insertion roller 16 allows the tip of the sandwiched film F to be inserted into the slit 17 ′ of the spool 17.
Since the locking hole is formed at the same time at the time of cutting by the cutter mechanism 13 at the film leading end as described above, the locking hole is hooked on the hook provided in the slit only by inserting it into the slit of the spool 17. It will be locked. The insertion of the leading end of the film into the slit 17 'of the spool 17 is performed when the turntable T holding the spool 17 stops at the third station (III).

The lower roller 16b of the insertion roller 16 can be pressed against or retracted from the upper roller 16a. Also, the lower insertion guide 25b of the insertion guide 25 at the end of the insertion roller can be similarly kept at an appropriate distance from the upper guide 25a or retracted. The timing of retracting the lower roller 16b and the lower insertion guide 25b is between the time when the leading end of the film is locked by the spool 17 and the time when the turntable T stops rotating.

Further, the leading end of the film F is inserted into the spool 17 by the insertion roller 16.
Stop by a signal when a sensor (not shown) detects that the film is locked, but the fixed-size sprocket 11, the feed roller 12, and the pull-out roller 14 rotate continuously until the film F reaches a specified length, and When F reaches a fixed length, it stops, and the cutter mechanism 13 operates to cut the film F.

The film F continuously fed out after the insertion roller 16 stops is tabbed between the extraction roller 14 and the insertion roller 16, but when this film portion bends below the nozzles 20a and 20b, a force for lifting the film is applied. It is bent downward by its own weight as shown by a two-dot chain line. At this time, above the guide rail 15, or the plate-like member
If the nozzles 30 and 31 capable of injecting compressed air downward are provided in appropriate places of the 18a and 18b, it is possible to forcibly make the deflection. As a result, it is possible to prevent the collision with the mechanical unit due to the inertial force of the film and the contact between the films. Further, it is more safe to provide a nozzle 41a at a lower front portion of the loop chamber 41 so that the film hits the bottom of the transport loop chamber 41 and does not suffer any damage such as scratches.

When the cutter mechanism 13 cuts the film F as described above,
The drawing roller 14 is driven again, and the trailing end of the film is sent out toward the guide rail 15 to be free.

Also, the spool with the film tip locked as described above
17 is the fourth station (IV) by turning the turntable T
To the drive source as shown in the perspective view of FIG.
The film F, which has been forcibly rotated in the winding direction by the engagement of the spool holder 43 with the spool holder 43 and has a completely free rear end, is exposed to airflow as shown in a perspective view of FIG. The scroll 50 is created with the precision shown in FIG. 6 (b). At this time, sensor 51
The driving source 46 is stopped by the signal catch of the signal F, and the tongue length l of the film F is maintained at a constant length.

In the film conveyance at the time of the film standard length described with the above-described apparatus example, the leading end of the film F to be measured by rotating the fixing sprocket 11 by a predetermined rotation is held by the air pressure by the ejection of the compressed air from the nozzles 20a and 20b, and the guide rail is held. Since the film F is guided to the insertion roller 16 accurately along the line 15, the contact pressure between the film F and the guide rail 15 is small, and the film can be prevented from being damaged.

When the leading end of the film F is nipped by the insertion roller 16 and locked by the spool, the lower roller and the lower chute of the insertion roller 16 escape and the film F is moved to the first position.
It bends as shown by the two-dot chain line in the figure. That is, since all film sizes are absorbed by the amount of flexure, size change is simplified, large versatility is obtained, and the film is small and compact.

For the film F whose leading end is locked by the spool 17 and whose trailing end is free, the spool 17 mounted on the chuck 43 on the turntable T reaches the fourth station (IV) and is driven to rotate in the winding direction. It is wound up by. At the time of winding, the film F is fed from a nozzle (not shown).
A suitable tension is applied while maintaining the winding angle of the film F on the spool 17 at a constant inclination angle by the compressed air blown to the film. This prevents fluttering of the rear end of the film F.

Now, when the scroll 50 is completed at the fourth station, the turntable T rotates and stops at the fifth station. Here, the scroll 50 may be collected, but here, the presence or absence of scrolling, the length of the film terminal portion, etc., and the scroll diameter of the scroll are checked. When the turntable T further rotates and stops at the sixth station, the scroll is caught and collected by the receiving holders 62 provided at equal intervals (here, divided into three) by the transfer turret 61, and the next pyrone is inserted and collected. The film is transferred to the cap-attached turntable 81, and finally a 135-type film containing pyrone is produced. The description of the structure is omitted.

FIG. 3 shows a second example of a method and apparatus for transporting a fixed-size film according to the present invention. The same parts as in the first example are denoted by the same reference numerals. This film transport device is provided with vacuum devices 71, 72, 73 above the guide rail 15,
This is different from the first example in that the film can be transported under a negative pressure above the film.

The bending of the film is performed by releasing the suction force of the intermediate vacuum device 72. Needless to say, a nozzle 31 for blowing downward compressed air may be provided.

〔The invention's effect〕

As described above, in the present invention, in creating a scroll of a photographic film, a chucking step of a spool,
The operation of each process such as the orientation process of the engagement position of the spool, the insertion and engagement process of the leading end of the film into the slit of the spool, and the winding process is performed separately at the corresponding station, so that the production time per scroll, that is, the cycle The time can be made much shorter than that of the conventional vertical connection, and various excellent effects such as improvement of work efficiency and stabilization can be realized.
