Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for manufacturing a roll diameter regulating disk for a photographic film.

[0002]

2. Description of the Related Art For the purpose of simplifying the loading of a photographic film cartridge into a camera, improving the working efficiency in a developing station, and improving the handling of the photographic film cartridge, the photographic film is wound up to the spool even up to its tip. The photo film patrone, in which the tip of the photo film is sent to the outside from the opening provided in the patrone body by rotating the spool after loading it in the camera body and loading it in the camera, is US Pat. No. 4,834,306. Description, No. 4832275, JP-A-3-376
No. 45, etc. In such a photographic film cartridge, since it is necessary to reliably transmit the rotation of the spool to the photographic film, a disk with a cup-shaped cross section is attached to both ends of the spool shaft,
The outer edges of the roll of the photo film are wrapped to prevent loosening in the patrone.

The above-mentioned disc is adapted to release the wrapping of the photographic film by being pressed by the edge portion of the photographic film to be deformed. Therefore, it is formed of a material such as plastic having a small thickness so that it can be easily deformed. A method for manufacturing such a disc is disclosed in Japanese Patent Laid-Open No. 2518/1992.
No. 41 and Japanese Unexamined Patent Publication No. 5-119436, a thermoplastic synthetic resin web wound in a roll shape is partially heated to be softened, and this heated portion is sucked by a vacuum pump and brought into close contact with a mold. A vacuum forming method is described. Also,
It is also described that the unevenness of the disk is formed by a pressure forming or a thermoforming press. JP-A-6-67360 and JP-A-6-242552 describe a molding step of forming a plurality of concave and convex shapes of a disk by vacuum molding, and thereafter, from the thermoplastic synthetic resin web to the inside and outside of the disk-shaped deformed portion. A method of punching a shape has been proposed.

The performance required as the material of the above-mentioned disk is that it is a thermoplastic material having a heat resistance of at least 80 ° C. or higher, and that it is resistant to deformation fatigue and bending fatigue when formed into a thin wall. It has excellent properties and further has little surface abrasion. Examples of materials that satisfy such requirements include modified PPE resin films, polycarbonate films, and polyolefin films. Since these thermoplastic synthetic resins are relatively expensive, the disk-shaped deformed portions are formed in a state where they are densely packed in a wide web in order to increase the material yield.

Further, when heating the thermoplastic synthetic resin as described above, it is necessary to perform heating corresponding to a high softening temperature. As a method of heating the thermoplastic synthetic resin web to a high temperature, a method of heating the web by contacting it with a heating plate, a radiant heating method of heating with radiant heat while passing under a heater or infrared light, heating There is a heating furnace system or the like in which the heating is carried out by passing through the created space.

[0006]

However, among the above heating methods, the radiant heating method and the heating furnace method are difficult to heat a wide range at a constant temperature, so that temperature unevenness is likely to be large, and vacuum pressure forming is difficult. In some cases, a defective disk may be manufactured due to a portion that cannot be sufficiently sucked.

In the heating plate method, the thermoplastic synthetic resin web can be heated to the highest temperature most uniformly among the above heating methods. Even if this heating plate method is used, the web is not uniformly contacted with the heating plate. When partially contacted, only that contact may extend. When the pressing of the web against the heating plate is performed by a vacuum pressure air forming mold, there is no escape area for the extended portion, and there is a problem that wrinkles remain. On the contrary, if there is a part that is not partially in contact with the whole of the web being in contact with the heating plate, the part is not softened, and thus suction can be performed by vacuum pressure forming. There is a problem that it can not be done and it becomes a bad disk.

The present invention has been made in view of the above problems, and it is an object of the present invention to uniformly heat a web of thermoplastic synthetic resin to produce a disc with high accuracy.

A flat film passage 17 is formed in the light-shielding lid 16 and serves as a passage for the photographic film 14 delivered from the inside of the cartridge body 10 when the light-shielding lid 16 is rotated to the open position. When the light-shielding lid 16 is rotated to the closed position, the opening (photo film entrance / exit) formed at the tip of the port portion 15 is completely closed, and the inside of the cartridge body 10 is in a light-shielding state.

A protrusion 18 is formed in the lower portion of the port portion 15 of the lower case 12. The protrusion 18 is provided on the spool 1
3 is a guide for picking up the leading end of the photographic film 14 wound around 3 and guiding it to the film passage 17.

Each of the disks 19 and 20 has an opening 1
9a and 20a are formed. The spool 13 is fitted into a predetermined position of the spool 13 by inserting the spool 13 into the openings 19a and 20a, and is rotatably mounted on the spool 13. On the outer circumference of the disks 19 and 20, there is a lip 2
1 project from each other so as to face each other, and partially surround the outermost periphery of the photo film 14 wound around the spool 13 from both ends.

When the use indicating component 23 is fitted into the spool 13, the disc 20 has the clutch claw 24 and the engaging hole 25 of the disc 20 engaged with each other when the spool 13 is rotated in the film feeding direction, Disk 20
Can be forcibly rotated. Further, when the spool 13 is rotated in the film winding direction, the disc 20 can freely rotate without engaging the clutch claw 24 and the engaging hole 25 of the disc 20. Also, the other disc 1
9 remains free to rotate with respect to the spool 13. In addition,
A fan-shaped display plate 23a is integrated with the use display component 23, and the state of use of the photographic film cartridge can be determined by checking the position through a display window formed in the cartridge body 10.

Side ribs 26 are provided on inner side walls of the upper case 11 and the lower case 12 to prevent the disks 19 and 20 from spreading. A fan-shaped plate 27 is fixed to the spool 13, and a data flange label 28 is attached to the surface thereof. A bar code is radially written on the label 28, and the bar code is photoelectrically detected through a window 29 formed on the side surface of the cartridge body 10 when the spool 13 is rotated. As a result, the type information of the photographic film 14 stored in the Patrone main body 10,

The film type display and unique Patrone number are displayed.

The spool lock component 31 locks the spool 13 so that it does not rotate when the light shielding lid 16 is rotated to the closed position. This lock is released when the light shielding cover 16 moves to the open position. Reference numeral 32 denotes a lock pole integrally formed with the upper case 11, and the light blocking cover 16 is locked by the lock pole 32 when the cover 16 is turned to the closed position. This lock is released when the photographic film cartridge is set in a device such as a camera or a display device by the opening mechanism of the light shielding lid 16 provided in these devices. Instead of using the light-shielding lid 16, it is possible to form a film passage in the inner wall of the port portion 15 and attach a telemp to the film passage to keep the inside of the cartridge body 10 light-tight.

As shown in FIG. 11, the photographic film 14 is used.
When the film is completely wound inside the cartridge body 10, the outermost periphery of the photographic film 14 is the disk 19, 20.
Are partially wrapped by the lips 21 and 21 to prevent loosening of the winding from the spool 13. As a result, when the spool 13 rotates in the feeding direction of the photo film 14, the photo film 14 rotates together with the spool 13.

The side ribs 26 provided on the inner side walls of the upper and lower cases 11 and 12 regulate the disks 19 and 20 so that they do not spread out from each other. , Side ribs 26 facing each other
The spacing between them has been increased. Therefore, when the tip of the photographic film 14 is scooped up by the protrusions 18 and then advances to the film passage 17, the disks 19 and 20 spread slightly outward, so that the photographic film 14 has the lips 21 and 2.
A gutter-shaped curl is made and sent out from between the two.

The same effect can be expected if the side ribs 26 are provided on only one side. Further, as a method of releasing the film winding loosening prevention of the lip 21, a pair of separation claws are provided on both sides in the film width direction, and the outer surfaces of the pair of separation claws are partially moved toward the direction in which the pair of lips are separated from each other. It may be always deformed.

When the above-mentioned photographic film cartridge is loaded in the camera, the lock of the light shielding lid 16 by the lock pole 32 is released by the mechanism on the camera side, and then the light shielding lid 16 is rotated in the opening direction. Thereafter, the spool 13 is driven in the feeding direction, and feeding of the photographic film 14 is started. Lip 2 formed on the outer circumference of the disks 19 and 20
Since the photo films 14 prevent the photo film 14 from being loosened, the photo film 14 rotates together with the spool 13. During this rotation, the leading end of the photographic film 14 is picked up by the projection 18 and guided to the film passage 17.

When the tip of the photographic film 14 is guided to the film passage 17 in this manner, the lips 21, 21 are spread to both sides by the photographic film 14, so that the wrapping of the photographic film 14 is released inside the film passage 17. Since the one disk 20 is forcibly rotated in the delivery direction by the engagement of the clutch claw 24 and the locking hole 25, the force for delivering the photographic film 14 is strengthened.
In this way, the photographic film 14 comes to be sent out of the cartridge main body 10.

At the time of rewinding, the spool 13 is rotated in the opposite direction. Since the rear end of the photographic film 14 is locked to the spool 13, the photographic film 14 is wound inside the cartridge body 10 by the reverse rotation of the spool 13. At this time, the disks 19 and 20 are spread out in the interior of the film passage 17, and the photographic film 14 is drawn between the disks 19 and 20 and wound around the spool 13.

As shown in FIGS. 12A and 12B, the disks 19 and 20 have the same contour shape. The openings 19a and 20a are formed on a surface 39 which is recessed one step from the surface 38 which aligns both ends of the photographic film 14. The lip 21 projects on the outer periphery of the surface 38 so as to face the other disks 19 and 20, respectively, and partially wraps the outermost periphery of the photographic film 14 wound around the spool 13 from both end surface sides.

A collar 22 is integrally provided on the outer periphery of the lip 21. The flange 22 functions to reinforce the lip 21 so as not to spread. In addition, in order to have a function of guiding the photographic film 14 to easily enter the inside of the lip 21 when the film is rolled in,
The flange 22 has a cross-sectional shape that is inclined so that the tips of the opposing surfaces 22a are separated from each other.

In this embodiment, the number of disc female dies 64 in the die 58 is 10 along the web conveying direction X as shown in FIG. 4, which is a plan view of the web 40 after vacuum pressure forming.
There are a total of 60 rows and 6 rows in a direction orthogonal to the web transport direction X, and 60 disk-shaped deforming portions 65 are formed on the web 40 by one shot molding.

Further, the die 58 includes a female die 6 for disc.
In addition to 4, a positioning female die (not shown) for forming a circular positioning recess 69 used for positioning when punching the disc-shaped deforming portion 65 from the web 40 and the disc-shaped deforming portion 65 are punched. A guide female die (not shown) that forms a guide groove 70 that serves as a guide when the web 40 is moved, and a rib 71 that reinforces the web 40.

It is arranged at a position deviated from 6. Also, the chain double-dashed line 7
There is also an air passage 75 arranged in the central portion of 6, but since this portion corresponds to the openings 19a and 20a punched out when manufacturing the disks 19 and 20, slight deformation does not pose a problem.

If the diameter D of the air passage 75 is too large, it may rupture when the web 40 is sucked.
If it is too small, the web 40 cannot be sucked and the web 4 is properly
There is a problem that 0 cannot be heated. Table 1 below shows the results of experiments in which the diameter D of the air passage 75 was changed to several types and the adsorption of the web 40 and the presence or absence of rupture were performed. The adsorptivity is an evaluation of the contact state of the web 40 with the heating plate 57, and the mark “⊚” is the most appropriate for the web 40.
Shows the result of being able to contact with the heating plate 57, and the evaluation is lowered in the order of “◯” and “Δ”. In the evaluation of rupture, the mark "⊚" indicates the result that the web 40 was not deformed, and the evaluation was decreased in the order of "○" and "△" below, and the result of rupturing the web 40 was indicated by "x". Show.

[0047]

[Table 1]

From the results shown in Table 1 above, it is understood that the web 40 can be adsorbed to the heating plate 57 most appropriately when the diameter D of the air passage 75 is 0.4 mm and 0.5 mm. The evaluation of the adsorptivity when the diameter D is 0.3 mm is “Δ”, but it is not so much affected. The burst evaluation when the diameter D is 0.6 mm is also “Δ”, but since the air passage 75 is not directly formed in the disk-shaped deforming portion 65 and the positioning recess 69, slight deformation is acceptable. It is a range. From these results,
The diameter D of the air passage 75 is preferably in the range of 0.3 to 0.6 mm. The diameter D of the air passage 75 is preferably 0.35 to 0.55 mm, particularly preferably 0.4 to 0.5 mm.

Further, when the web 40 is adsorbed by the heating plate 57, an air pocket is formed between the heating plate 57 and the web 40, and that portion extends and the proper disk-shaped deformed portion 65 cannot be formed. Sometimes. In order to prevent this, the surface 57a of the heating plate 57 has a thickness of 0.5 to 20 μm.
It is considered to have a surface roughness of some degree. As a result, the heating plate 57
Since a slight gap formed between the surface 57a of the sheet and the web 40 can be used to suck the air between them,
The web 40 can be heated more appropriately. If the surface of the heating plate 57 is too rough, the disc 1
The surface roughness of the heating plate 57 may remain on the surfaces of the heating plates 9 and 20, which may cause defective rotation. Therefore, the surface roughness of the heating plate 57 is preferably not more than 20 μm.
