Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method of cutting photographic film into a certain length and winding the film by locking the end of the film to a spool, that is, creating a scroll of film; Regarding equipment.

[Conventional technology]

Conventionally, when creating a scroll of photographic film, methods and devices for winding the film have been known, for example, those described in Japanese Patent Application Laid-open No. 115215/1983. In the former case, ■ rotate the fixed-length sprocket at a predetermined rate to feed out a long film, ■ use a cutter to cut the film into a single film of the specified length, ■ lock the tip of the film on the spool, ■ perform primary winding, and unwind the film. This device uses a method in which the transport path is opened, the film is allowed to fall, and (2) the film is wound to a predetermined accuracy using secondary winding.

[Problem to be solved by the invention]

However, the device and method of JP-A-52-115215 mentioned above requires two winding stations, making the structure complicated, and the spool handle +L and the primary winding are performed at the same station in chronological order. The cycle time is not shortened because it is connected vertically. In addition, the film transport chute between the fixed-length sprocket and the primary winding requires a maximum fixed-length length (for example, 36-shot film length), which increases the size of the equipment. Furthermore, when processing a short film, the film after being punched to a fixed length must be conveyed by a feed roller at the spool position, which tends to cause quality problems such as scratches.

The present invention has been made in view of the above circumstances, and is a method and apparatus for making a scroll of photographic film, particularly 135 type film, which reduces equipment, improves and stabilizes work efficiency, and increases productivity. is intended to provide.

〔Example〕

Next, embodiments of the present invention will be described based on the accompanying drawings.

FIG. 1 is an implicit side view of the entire film school discipline method B and apparatus according to the first example of the present invention, FIG. 2 is a cross-sectional view of the main part of film conveyance, and FIG. ) is a side view showing the spool orientation, and (b) is a cross-sectional view thereof. In the figure, reference numeral 6 denotes a rail chute for supplying a spool, which are continuously arranged with long bosses and short bosses aligned in a fixed direction. The shutters 7a and 7b alternately move in and out, and the spools 17 are chucked one by one into the spool chuck 43 on the turret T. This spool supply chucking position is the first station (1)
It is. Next, the turntable T is moved to the second stage (n
) and attached to the spool at the first station]
7 is engaged with the servo motor 44 at this second station and rotated, the notch 17a engages with the orientation pawl 42, the direction of the slit 17' of the spool 17 is determined, and the turntable rotates. The spool chuck 43 of the spool oriented with this slit position is located at the third station (I[I). At this time, of course, at the second station, the orientation of the spool supplied to the succeeding spool chuck is performed, and at the first station, the subsequent spool is further supplied and attached to the spool chuck 43.

Next, the functions of the third station will be described. Reference numeral 11 denotes a fixed length sprocket, to which a long film F drawn out from a source magazine (not shown) is supplied via a tension adjustment device. This fixed length sprocket 11 feeds the film F at a rotational speed corresponding to the cutting length thereof and supplies it to the feed roller 12. The feed roller 12 supplies the film F sent from the fixed length sprocket 11 to the drawing roller 14 through between the upper and lower blades of the cutter mechanism 13. The cutter mechanism 13 cuts the film F into a predetermined length in response to the rotation speed of the fixed length sprocket 11. This cutting blade can simultaneously punch out a locking hole that locks into a hook provided in the slit of the spool. The pull-out roller 14 guides the film F through the guide rail 15 to the insertion roller 16 in front.

The guide rail 15 is comprised of a pair of plate-like members 18a and 18b, which are installed between the pull-out roller 14 and the insertion roller 16 with an interval slightly wider than the width of the film F, as shown in the second figure.
and a hook-shaped film sliding surface 1 on the inner surface of the upper edge.
It consists of 9a and 19b. This sliding surface 19a.

Nozzles 20a and 20b are installed in the plate members 18a and 18b along the direction in which the film travels to eject compressed air that penetrates the wall surface diagonally so that both edges in the width direction of the film F are brought into sliding contact with the film F in the direction of movement of the film 19b. It is located. These nozzles 20a and 20b are air passages 22a and 22a in ducts 21a and 21b provided on the outer walls of plate members 18a and 18b, respectively.
It is connected to a compressed air source (not shown) via 22b. Therefore, both edges of the film F in the width direction are connected to the nozzle 20a.
, 20b, the sliding surface 19a is
, 19b.

The insertion guide 25 of the insertion roller 16 inserts the tip of the sandwiched film F into the slit 17' of the spool 17, but a locking hole is formed in the tip of the film at the same time as it is cut by the cutter mechanism 13 as described above. Therefore, simply by inserting the spool into the slit of the spool 17, the locking hole is hooked onto the hook provided in the slit and the spool is locked. The leading end of the film is inserted into the slit 17' of the spool 17 when the turntable T holding the spool 17 stops at the third station (I[I).

The lower roller 16b of this insertion roller 16 is connected to the upper roller 16
It is possible to press against or retreat from a. Further, the lower insertion guide 25b of the insertion guide 25 located at the tip of the insertion roller can similarly be maintained at an appropriate distance from the upper guide 25a or can be retracted. This lower roller 16b and lower insertion guide 25b
The timing for retracting is the time after the leading end of the film is latched to the spool 17 until the turntable T stops rotating.

In addition, the insertion roller 16 has the tip of the film F on the spool 1.
However, the fixed length sprocket IL feed roller 12 and the pull-out roller 14 continue to rotate until the film F reaches the specified length. When the film F reaches a fixed length, it stops, and the cutter mechanism 13 operates to cut the film F.
cut.

The film F that continues to be fed out after the insertion roller 16 stops is overlapped between the pull-out roller 14 and the insertion roller 16, and this film portion is exposed to the nozzle 20a.

When the film is bent below 20b, no force is applied to lift the film, and it bends downward due to its own weight as shown by the two-dot chain line. At this time, if nozzles 30 and 31 capable of jetting compressed air downward are provided above the guide rail 15 or at appropriate locations on the plate members 18a and 18b, the deflection can be forcibly created. It becomes possible.

This prevents the film from colliding with the mechanical part due to inertial force and preventing the films from coming into contact with each other. In addition, a nozzle 4 is installed at the front lower part of the loop chamber 41 so that the film does not hit the bottom of the transport loop chamber 41 and suffer damage such as scratches.
It is even safer if 1a is provided.

When the cutter mechanism 13 cuts the film F as described above,
The pulling roller 14 is driven again, and the rear end of the film is sent out to the guide rail 15 side to form a 7-lead film.

In addition, as mentioned above, the spool 1 with the film tip locked
7 is the fourth station (IV
), where the drive source 46 and spool holder 43 engage as shown in the perspective view of FIG. As shown in the perspective view of FIG. 6(a), the scroll 50 is produced as shown in the perspective view of FIG. 6(b) by winding with a predetermined precision while applying an air flow. At this time, the drive source 46 is stopped by the signal caught by the sensor 51, and the length Q of the tongue end of the film F is maintained at a constant length.

As explained in conjunction with the above device example, when transporting a film to a fixed length, the tip of the film F that is fixed to a fixed length by rotating the fixed length sprocket 11 in a predetermined manner is a nozzle 20a.

Since the film is held by the air pressure generated by the jet of compressed air from the film 20b and guided accurately along the guide rail 15 to the insertion roller 16, the contact pressure between the film F and the guide rail 15 is small, and damage to the film can be prevented. .

When the leading end of the film F is clamped by the insertion roller 16 and locked on the spool, the lower roller and the lower chute of the insertion roller 16 escape, and the film F moves as shown by the two-dot chain line in FIG. bend.

That is, all film sizes can be accommodated by this amount of deflection, making it easy to change sizes, providing great versatility, and being small and compact.

The film F, whose front end is locked to the spool 17 and whose rear end is free, is rotated in the winding direction when the spool 17 attached to the chuck 43 on the turntable T reaches the fourth station (IT). It is wound up by this. During winding, the spool 1 of the film F is blown by compressed air from a nozzle (not shown) to the film F.
Appropriate tension is applied while maintaining the winding angle to 7 at a constant inclination angle.

This prevents the rear end of the film F from flapping.

Now, when the scroll 50 is completed at the fourth station, the turntable T rotates and stops at the fifth station. At this point, the scroll 50 may be collected, but at this point, the presence or absence of the scroll is checked, the length of the end portion of the film, etc., and the winding diameter of the scroll are checked.

When the turntable T rotates further and stops at the sixth station, the scroll is grabbed by the receiving holders 62 provided at equal intervals (in this case, divided into three) on the transformer 7 arteret 61 and collected, and the scroll is collected and sent to the next battle station. Inserted and transferred to the cap mounting turntable 81,
Eventually, 135 types of cartridge films were created. A description of its structure will be omitted.

Incidentally, FIG. 3 shows a second example of the method and apparatus for conveying a fixed length film according to the present invention.

Note that the same parts as in the first example are indicated by the same reference numerals. This film transport device has a vacuum device 71 installed above the guide rail 15.
, 72, 73 are provided so that the film can be conveyed under negative pressure above the film.

The film is deflected by releasing the suction force of the intermediate vacuum device 72, but it goes without saying that a nozzle 31 for spraying downward compressed air may also be provided.

〔Effect of the invention〕

As described above, in the production of a scroll of photographic film in the present invention, each process such as the spool loading process, the spool locking position orientation process, the insertion and locking process of the film tip into the spool slit, and the winding process is performed. Since each scroll is divided into corresponding stations, the creation time for each scroll, that is, the cycle time, can be much shorter than that of conventional vertically connected scrolls, which improves work efficiency and stabilizes the process. It has various excellent effects.
