A photographic film locking device (hereinafter simply referred to as a locking device) 1 is a photographic film (hereinafter simply referred to as a film) 3 supplied from a film supply device 2.
After the tip of the is locked to the spool provided in the cartridge 4, automatic winding is performed. The locking device 1 generally has a structure in which a fixing portion 21 for positioning and fixing the cartridge 4 on the pedestal 5, a cam mechanism 31 for rotationally driving a guide plate 32, which will be described later, and a positional deviation when locking the film 4 are prevented. The film retainer 42 and the cam mechanism 41, the sensor 51 for detecting the film 3, the first transport roller 61 whose rotation speed is controlled, the second transport roller 71 whose rotation speed is constantly controlled, and the bending of the film 3 are allowed. It comprises a reservoir portion 81 forming a buffer, a control means (not shown) for controlling the operation of each of the above-mentioned components, and the like.

For convenience of explanation, the structure of the cartridge 4 will be explained prior to the locking operation of the film 3. The cartridge 4 is formed in a substantially cylindrical shape as shown in FIG. An opening 11 is formed along the line. The opening 11 is for winding the film 3 in and out. And in Patrone 4,
A spool 12 having a so-called bobbin shape as shown in FIG. 4 is rotatably provided. The spool 12 is integrally provided with a pair of flanges 12a, and the film 3 is wound around the shaft portion 12b between the pair of flanges 12a.

Both ends of the spool 12 are exposed to the side surface of the cartridge 4, and a key 16 is provided on the exposed portion. The key 16 is for engaging the spool driving member when the cartridge 4 is attached to the locking device 1 and rotating the spool 12 when winding or removing the film 3. As shown in FIG. 4, the spool 12
A slit 14 is formed on the shaft portion 12b of the slit 1.
A pair of claws 15 and a pressing rib 17 are provided inside the pressing member 4, and the pressing rib 17 projects downward between the pair of claws 15. The slit 14 has an insertion opening on the right side in FIG. 4, and when the film 3 is locked, its end is inserted into the spool 12 through the insertion opening.

On the other hand, a pair of locking openings 3a are formed at the ends of the film 3 so that when the film 3 is wound into the cartridge 4, it is locked by a pair of claws 15 formed on the spool 12. . Further, a pair of locking openings 3b are formed outside the pair of locking openings 3a so that the claw 32a formed on the guide plate 32 can be locked when the film 4 is wound. The perforations 3c are for transporting the film 4, but can also be used for detecting the position of the film 4 by detecting the number thereof.

Next, the winding operation of the film 3 will be described. As shown in FIG. 3, at the winding start time T1, the first and second transport rollers 61 and 71 are rotationally driven. However, both are driven by separate drive systems, and the rotation speeds are controlled to the same speed at this point. Further, the reservoir portion 81 is provided with a rotating plate 80 for forming an appropriate film transport path except when forming a buffer. The rotating plate 80 is provided with a rotating roller 82 at its end, and is rotatable around a fulcrum roller 83. When the first and second transport rollers 61 and 71 are rotating at a constant speed, the rotation roller 82 provided on the rotation plate 80
Is not lifted as indicated by the solid line, and the fulcrum roller 8
3 and the end roller 84. Therefore, the film 3 supplied from the film supply device 2 is first conveyed from the right side to the left side in FIG. 1 by the second conveying roller 71, and then is conveyed in the direction of the cartridge 4 by the first conveying roller 61.

The first and second conveying rollers 61, 71
The rotation speed is controlled by an individual drive system. To describe an example of the rotation speed, the rotation speed of the second conveyance roller 71 is controlled to a constant speed of 100 mm / sec.
The rotation speed of can be changed to a speed of 100 mm / sec or more.

When the film 4 passes the installation position of the sensor 51, the end portion of the film 4 is detected or the perforation 3 is detected.
The position of the film 3 is detected by counting c. Based on this detection, the cam mechanism 41 is driven, as shown at time T2, so that the film retainer 42 does not move downward and the film 4 does not retract upward, in other words, the position is regulated from the upper side so as not to deform, and The rotation of the first transport roller 61 is stopped. However, the second transport roller 71
Since the film is rotating, the film 3 is continuously conveyed, so that the film is bent upward in the reservoir portion 81 as shown by the solid line. Therefore, the first transport roller 61
Even if the rotation is controlled to stop, the film supply device 2 can continue to convey the film. At this time, the rotating plate 80 does not come into contact with the film 3 and the rotating roller 82 provided at the end is in contact with the film 3, so that the film 3 is not scratched by sliding contact.

Looking at the situation of the film 3 at the time T2, the end portions are positioned at predetermined positions and are in a state of not moving, and the claws 32a formed on the guide plate 32 are fitted to the pair of locking openings 3b formed on the film 4. The situation is such that it is easily inserted, that is, locked. Therefore, the cam drive mechanism 31 is driven to rotate the guide plate 32 counterclockwise. By the way, in this embodiment, the guide plate 32 is rotated to move the locking hole 3a of the film 3
The time required to lock the pair of claws 15 is 0.6
It is set to about a second. Therefore, 100 mm / sec × 0.6 sec = 60 between the first and second conveyance rollers 61 and 71.
A buffer of mm (total length of the bent portion of the film) is required, and the height of the bent portion is about 30 mm.

The guide plate 32 is formed in an arc shape when viewed from the side, and its base is fixed to a pair of rotating members 33. The rotating member 33 is rotatably supported by a shaft 34 and one end thereof. Are connected to the rotating body 36 by the connecting member 35. Therefore, when the rotating body 36 is rotationally driven at time T2,
The guide plate 32 rotates counterclockwise from the position shown by the solid line in FIG. 1, and the claws 32a and 32b approach the pair of locking ports 3b as shown in FIG. Figure 4
As shown in (A), the end portion of the film 3 is locked.

Then, the guide plate 32 continues to rotate as it is, the end portion of the film 3 is drawn into the cartridge 4 through the opening 11 as shown in FIG. 4 (B), and the spool as shown in FIG. 4 (C). It is pulled up to 12, and the pair of locking holes 3a are locked to the pair of claws 15. Therefore, the end of the film 3 is completely locked by the claw 15. The guide plate 32 is the film 3
It is preferable that the first transport roller 61 is in an idle state with the driving force interrupted while it is locked and rotating, but is rotated at a speed equal to the moving speed of the film 3. May be. Since the cam mechanism 31 continues to be driven, the rotation of the guide plate 32 is changed from the counterclockwise direction to the clockwise direction as shown at time T3.
Since the end portion of is locked to the claw 15, only the guide plate 32 rotates clockwise. Therefore, the claw 32a is engaged with the locking port 3b.
After getting out of it, it double-acts to its original position as shown in FIG. 4 (A).

Next, as shown at time T4, when the first conveying roller 61 is rotationally driven at 100 mm / sec, the flexure formed during the locking operation of the film 3 is conveyed as it is. . At the same time, the spool 12 is rotated via the key 16 to wind the film 3 around the shaft portion 12b as shown in FIG. 4 (B). Then, after the film 3 having a predetermined length is wound, the rotation of the first and second transport rollers 61 and 71 and the spool 12 is stopped as shown at time T5, and the winding is completed. As explained above,
In this embodiment, when the film 3 is wound into the cartridge 4, it is not necessary to temporarily stop the transport of the film 3 by the film supply device 2, and the winding operation can be performed efficiently and completely automatically.

Next, a photographic film separating device will be described with reference to FIGS. 5 is a schematic configuration diagram illustrating the configuration of a photographic film separating device (hereinafter, simply referred to as a separating device), FIG. 6 is a time chart illustrating the separating operation, and FIG. 7 is an example of a release plate.

The release plate 111 is separated by a notch portion 111a formed at the tip of the release plate 111.
While escaping the ribs 16 formed on the side, insert a pair of tongue pieces 111b formed on both sides between the claw 15 and the end of the film 3 to lift the film 3, and pull out the locking port 3a from the claw 15. It is carried out by

Next, the separating operation of the film 3 and the nail 15 will be described. While the film 3 is being developed, the first and second transport rollers 61 and 71 are simultaneously driven to rotate at a constant speed as shown at time T11 in FIG. And T12
As shown at the time point, a predetermined length (50 m
When the sensor 51 detects a specific portion on the front side (about m), the rotation speed of the first transport roller 61 is controlled to be high. The detection of the specific portion of the film 3 by the sensor 51 is performed by counting the perforations 3c or the like as described above. Further, the high speed control of the first transport roller 61 is 100 mm / sec × 0.6 sec = 60 mm as in the above.
The speed is controlled so that the buffer set by is formed.

However, since the rotation speed of the second transport roller 71 is constant, the film 3 is stored in the reservoir portion 81.
Bending occurs and the roller 82 is lifted as shown by the solid line in FIG. When the first transport roller 61 is controlled to stop rotating as shown at time T13 after the film 3 is bent, the film 3 is transported on the right side from the reservoir portion 81, but the film 3 on the left side. Is stopped.

When the trailing edge of the film 3 is stopped at T13, the cam mechanism 31 is driven and the rotating member 33 is rotated counterclockwise to move the release plate 111 from the lower side of the film 3 into the opening 11. Push into. The separating operation of the film 3 will be described below with reference to FIG. 6. By rotating the rotating member 33, the release plate 111 is pushed into the spool 12 as shown in FIG. And a pair of tongue pieces 1
11b moves along the slope of the claw 15 and pushes up so that the locking port 3a is pulled out from the claw 15. This pushing-up is performed by the pair of tongue pieces 111b being guided by the inclined surface of the claw 15, and as shown in FIG.
Comes out of the nail 15 completely.

Next, when the first conveying roller 61 is driven to rotate again as shown at time T14, the stopped film 3 is pulled to the right, so that the end of the film 3 is removed as shown in FIG. 6 (C). Completely separate from spool 12. T1
After the fourth point, the release mechanism 111 is released by the cam mechanism 31.
After the film 3 is conveyed, the first and second conveying rollers 61 and 71 are controlled to stop rotating as shown at time T15, and the separating operation is completed.

As described above, the photographic film separating apparatus shown in this embodiment ensures that the end of the film is temporarily stopped when separating the end of the film from the end locking means. The film can be separated and continued to be fed, and the film separating operation and the feeding operation can be efficiently performed. Although the embodiments of the present invention have been described above, the present invention is not limited to the above. For example, the tip shapes of the guide plate and the release plate are appropriately deflected according to the shape of the end locking means formed on the spool. Further, the device that interlocks with the separating device is not limited to the development processing device, and the device that interlocks with the locking device is not limited to the film supply device.

[0031]
