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 accommodating a patrone in which a fixed size film of photographic light-sensitive material is wound and accommodated in a packaging container.

[0002]

2. Description of the Related Art When wrapping a photographic light-sensitive material film, a process of cutting the original roll of the photographic light-sensitive material film into a fixed-size film and storing the film in a patrone, a process of storing the patrone in a wrapping container, and a step of externally mounting the film. There is a process of putting in a box to make a final packaging form.

[0003] The present invention relates to a process of storing a patrone in a packaging container. However, the problem here is that the end of the fixed-size film protrudes from the patrone in a tongue shape, and this is placed around the outer periphery of the patrone. It is necessary that the patrone, including this portion, be wrapped and securely housed in the packaging container.

The reason why the end of the fixed-size film protrudes from the patrone in the form of a tongue is, of course, because it is necessary to load the patrone into the camera and pull out the film from the patrone at the time of photographing. The presence of this tongue makes the process of storing the patrone in a packaging container quite complicated.

Furthermore, even if the tongue portion is once housed in a packaging container, recently, many cameras have a mechanism for automatically carrying out the operation of loading the patrone, and the camera has come out of the patrone. If the tongue part is deformed, it may be a problem at that stage.

Therefore, in the step of storing the patrone in the packaging container, it is necessary to ensure that the patrone is stored in the packaging container and that the tongue-shaped portion is not deformed due to excessive force. Must.

In the prior art, one of the cartridge and the container is rotated about the longitudinal axis of the cartridge at the same time as the transfer of the cartridge (patrone), so that the leader of the film (the tongue portion of the fixed-size film) and the container are rotated. A method is known in which a film leader is wound around a cartridge and inserted into a container by a relative movement at the time of engagement with a rim (see JP-A-9-5947).

However, this method has a problem that the film is frequently deformed when the film comes into contact with the container at the time of insertion.

A method is also known in which a fixed-size film is once wound around the outer periphery of a cartridge, and then inserted into a container in the next step so that the fixed-size film is not unraveled (for example, Japanese Patent Application Laid-Open No. 11-265043). Reference).

[0010] However, in this method, the winding and the insertion into the container are performed at different stations, so that the equipment becomes large, and there is a problem that the productivity is reduced due to troubles such as unraveling during the transfer of the wound patrone.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a view for explaining a process of storing a cartridge in which a fixed-size film is wound and stored in a packaging container.

The apparatus will be described later. First, the procedure will be described. First, the patrone 1 already containing the photosensitive film in the dark room is further stored in the packaging container 4 and the cap 5 of the packaging container is put on. . Usually, after that, packaging and packing with a plastic film are usually further performed. However, work in a dark room may be referred to as an interior process, and the subsequent processes may be referred to as an exterior process. The present invention provides a patrone 1 containing a photosensitive film.
Is further stored in the packaging container 4.

That is, the patrone 1 shown at the upper right of FIG.
In the step of storing the film in the packaging container 4 shown at the lower right, the problem is that the tongue 3 at the end of the fixed-size film comes out of the patrone. The present invention relates to a method and a device therefor which need to be securely contained in a packaging container.

FIG. 2 is a top view showing, as an example of the embodiment, a packaging apparatus 10 for actually performing the work steps shown in FIG. Inside the fixed outer frame 13, there is a rotating packaging container transport member 11. 2, the packaging container 4 is taken into one of the holding grooves 14 of the packaging container conveying member 11, and the cartridge 1 containing the photosensitive film is stored in the upper part (B) of FIG. . Further, when the packaging container transporting member 11 rotates and the cap 5 is fitted to the packaging container 4 at the middle left part (C), and rotates to the position (D) in the lower part of the figure,
The packaging container 4 fitted with the cap 5 is taken out of the apparatus.

Next, FIG. 3 illustrates the main part of the present invention, and illustrates an embodiment thereof. As described above, according to the present invention, when storing the patrone in the packaging container, the end of the fixed-size film protrudes from the patrone in a tongue shape, so that the film is wound around the outer wall of the patrone, and this portion is securely placed in the packaging container. FIG. 3 illustrates this.

FIG. 4 is a sectional view of the embodiment shown in FIG. When the patrone 1 is inserted into the packaging container 4, a guide cylinder 20 having an insertion port 21 having a larger circumference than the discharge port 22 is interposed. 23 is an insertion port 21 to a discharge port 22
, And it is preferable to have umbrella-shaped irregularities 25 here. The patrone 1 is connected to the guide cylinder 20
When the cartridge 1 is inserted into the packaging container 4, the tongue 3 at the end of the fixed-size film is wound around the outer wall of the cartridge.
It does not hinder that.

The angle θ of the mortar-shaped guide surface 23 formed from the insertion port to the discharge port of the guide cylinder 20 is 2
0 to 50 ° is preferable, and 30 to 45 ° is more preferable.
If the angle of inclination is less than 20 °, the film tongue may be caught by the guide and cause an abnormal insertion.
If the angle is larger than 50 °, the film may be broken or a pressure flaw may occur during insertion.

The distance between the guide cylinder 20 and the packaging container 4 is
0.5 to 1.5 mm is desirable. The diameter of the discharge port 22 of the guide cylinder 20 is preferably set to be substantially the same as the diameter of the packaging container.

At this time, if not only the guide cylinder 20 but also the patrone is rotated at a low speed in the reverse direction, the insertion can be performed more stably. The rotation speeds of the patrone and the guide cylinder are opposite to each other, and it is preferable that the rotation speed V1 of the patrone is smaller than the rotation speed V2 of the guide cylinder, and the rotation speed V1 of the patrone is about one rotation by the end of insertion. The rotation speed V2 of the guide cylinder is more preferably 2 to 5 times V1.

Further, as shown in FIG. 5, when the insertion opening 21 is viewed from above, a groove or the like is formed on the guide surface 23 of the guide cylinder 20 to form an umbrella-shaped groove or the like, so that the guide cylinder 23 has The friction of the inclined surface increases, and the rotation makes it easier for the tongue to be wound around the patrone outer wall.

The mortar-shaped guide surface 23 from the insertion port 21 to the discharge port 22 is preferably mirror-finished and coated with titanium nitride or the like in order to prevent abrasion. Further, when a lubricant such as silicone oil is applied, not only wear of the guide but also a favorable effect on the scratch of the film tongue portion is obtained.

In order to supply the lubricant little by little, it is preferable to make it as shown in FIG. The suction pad 30 is used to transfer the patrone, and the upper portion of the patrone is sucked and held. A buff 31 impregnated with silicone oil as a lubricant is pressed against this portion to provide a thin coating mechanism. When the patrone 1 is inserted into the guide tube 20, the guide tube 23 gradually shifts to the mortar-shaped guide surface 23 of the guide cylinder, and a lubricating effect is obtained. The lubricant used at this time must of course not adversely affect the photosensitive material film. As a result, it is possible to prevent deformation of the tongue portion, scratches on the film, pressure fogging of the film, and the like due to an impact generated when the tongue portion is wound around the outer wall of the cartridge.

The holding groove 14 of the packaging container conveying member 11 shown in FIG. 2 preferably has some backlash when the packaging container is inserted slightly larger than the outer diameter of the packaging container 4. Thus, when the patrone is inserted from above, even if there is some variation in the insertion accuracy, the absorption correction can be performed here. Therefore, it is preferable that the diameter of the holding groove 14 is larger by 0.5 to 1.0 mm than the outer diameter of the packaging container.

[0032]

According to the present invention, the patrone in which the fixed-size film is wound and accommodated is efficiently and promptly stored in the packaging container, and at this time, the patrone is smoothly inserted without applying excessive force. It is possible to provide a patrone storage method and a patrone storage device in which the film tongue portion coming out of the cartridge is not deformed.
