Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic film take-out device which can take out an undeveloped film from a cartridge in a photo-developing process and stand by at a connection position with a leader.

[0002]

2. Description of the Related Art Conventionally, when developing an undeveloped film such as 110, 120 or 126, it is impossible to set the cartridge containing the undeveloped film in the film developing machine as it is. In the dark room, the undeveloped film was rewound into another cartridge (dedicated cartridge), and a leader was attached to the rear end of the rewound undeveloped film.

[0003]

However, since the undeveloped film was manually rewound into another cartridge in a dark bag or a dark room as in the prior art, the undeveloped film was sometimes mistaken for its inside and outside. . Further, there is a problem that the winding work takes time because it is done manually.

The present invention has been developed in view of the above points, and an object thereof is to automatically take out an undeveloped film from a cartridge and take it up, so that a conventional winding direction can be obtained. By eliminating mistakes, you can reliably wind the undeveloped film in a short time, and automatically put the trailing edge of the undeveloped film that has been wound up at the connection position with the leader. An object is to provide an automatic film take-out device.

[0005]

Accordingly, the present invention has the following configuration in order to effectively achieve the above object. That is, the film feeding means for rotating the spool shaft of the film cartridge containing the undeveloped film wound thereon, the light-shielding door opening / closing means for the cartridge, and the relationship between the rear end of the undeveloped film unwound from the cartridge and the spool shaft. A film locking releasing means for releasing the locking relationship, a case for accommodating an undeveloped film unwound from the cartridge, a winding shaft rotating means for rotating an undeveloped film winding shaft provided in the case, It is characterized in that it comprises a case moving means for moving the case to a predetermined position and a winding film feeding means for feeding the undeveloped film wound around the winding shaft of the case.

Further, the case 5 and the cartridge 9 described above.
The undeveloped film A unwound from the film is wound and temporarily stored, and a pair of undeveloped films A are provided via the connecting shaft 15. By rotating each case 5 by 180 °, the entrance / exit 13 of the undeveloped film A of one case 5 exits the guide passage 14 leading to the light shielding door 11 of the cartridge 9.
4A, the entrance / exit 13 of the undeveloped film A of the other case 5 faces the position where the undeveloped film A wound in the case 5 can be connected to the leader 17. In each case 5, a winding shaft 5a for winding the undeveloped film A, a leaf spring 5b, and a pressing roller 5c are provided.

A winding shaft rotating means 6 is provided for rotating the winding shaft 5a of the case 5 in the forward and reverse directions. The winding shaft rotating means 6 includes a motor 6a, a pulley 6b (or a sprocket), a belt 6c (or a chain).
A pulley 6d (or a sprocket), a gear 6e provided coaxially with the pulley 6d, a gear 6g meshed with the gear 6e and provided on the winding shaft 5a of the case 5
And a gear 6f that meshes with.

By driving the motor 6a, the pulley 6b, the belt 6c, the pulley 6d, the gear 6e, and the gear 6f.
Also, the take-up shaft 5a rotates via the gear 6g so that the undeveloped film A unwound from the cartridge 9 can be taken up on the take-up shaft 5a.

Further, case moving means 7 is provided for rotating and moving the pair of cases 5. The case moving means 7 includes a motor 7a, a pulley 7b (or sprocket), a belt 7c (or chain), and a pulley 7

By driving the motor 7a,
Support shaft 1 via pulley 7b, belt 7c, and pulley 7d
6 rotates, and each case 5 is rotated 180 ° via the connecting shaft 15.
It can be rotated one by one.

Further, a winding film feeding means 8 is provided for rotating the winding shaft 5a of the case 5 located on the side of the leader 17 to unwind the undeveloped film A wound on the winding shaft 5a. There is.

The take-up film feeding means 8 includes a motor 8a, a pulley 8b (or sprocket), a belt 8c (or chain), a pulley 8d (or sprocket), and a gear provided coaxially with the pulley 8d. 8e and a gear 8f that meshes with the gear 8e and meshes with a gear 8g provided on the winding shaft 5a of the case 5.

By driving the motor 8a, the pulley 8b, the belt 8c, the pulley 8d, the gear 8e, and the gear 8f.
The take-up shaft 5a rotates via the gear 8g and the undeveloped film a wound on the take-up shaft 5a is the leader 1
Unrolled to connect to 7.

The automatic film take-out apparatus 1 of the present invention is constructed as described above, and when the cartridge 9 containing the undeveloped film A wound therein is set at a predetermined position, the film feeding means 2 and the light-shielding door opening / closing means 3 are provided. The light-blocking door opening / closing means 3 opens the light-blocking door 11 of the cartridge 9, and the film feeding means 2
As a result, the spool shaft 10 of the cartridge 9 rotates in the direction in which the undeveloped film A is sent out, and the undeveloped film A that has been wound into the cartridge 9 is unwound to the case 5 side.

The front end of the undeveloped film A unwound from the cartridge 9 reaches the winding shaft 5a of the case 5 and is entangled with the winding shaft 5a. The winding shaft 5a of No. 5 is wound around.

At the time when the winding of the undeveloped film A by the winding shaft 5a is almost completed, the film locking releasing means 4 is actuated and the releasing arm 4f is inserted into the cartridge 9.
The rear end of the undeveloped film A, which is locked to the spool shaft 10, is separated from the spool shaft 10. The undeveloped film A separated from the spool shaft 10 is completely wound around the winding shaft 5a of the case 5. When the undeveloped film A is completely detached from the spool shaft 10, the film release means 4 is actuated to return the release arm 4f to its original position. Further, the means 2, 3 and 6 respectively stop operating.

When the winding and storing of the undeveloped film A in the case 5 is completed as described above, the case moving means 7 is actuated, and the case 5 in which the undeveloped film A is rolled and stored is 180.
Rotate and move to the position where the reader 17 stands by. Further, the other case 5 in the standby position of the leader 17 moves to a position where the undeveloped film A unwound from the cartridge 9 is wound up.

The case 5 which has moved to the standby position of the leader 17 unwinds the undeveloped film A which is wound and stored by the operation of the winding film feeding means 8.
The rear end of the undeveloped film A is locked in the locking hole (not shown) of the leader 17.

The undeveloped film A thus stored in the cartridge 9 is automatically wound into the case 5, and the position of the case 5 is changed by the rotational movement to face the standby position of the reader 17.

It is also possible to arrange the above-mentioned automatic film take-out devices 1 side by side and simultaneously wind the undeveloped film A from a plurality of cartridges 9 so as to face the positions of the respective readers 17 waiting at a predetermined position.

[0027]

As described above, according to the automatic film take-out apparatus of the present invention, the undeveloped film can be taken out automatically from the cartridge and taken up, which makes it possible to prevent the wrong take-up direction from occurring as in the conventional case. It can be lost. In addition, the undeveloped film stored in the cartridge can be surely wound up in a short time in a case, and automatically wait at the connection position with the reader.
Work efficiency can be further improved.
