Abstract

PURPOSE:To efficiently produce the camera by winding an unexposed long-sized film, then cutting the film and pulling off the winding core, loading the bull- wound film into the film housing chamber of a camera body and attaching a cover to the camera body. CONSTITUTION:The film 100 is cut by a cutter 105 and is then transported to a turn table 1. The table 1 rotates intermittently and has 4 stations A, B, C, D. The camera body 3 is supplied by a conveyor 107 to the station A. The bull-wound film 2 standing by on the station B descends and is housed into the film housing chamber 3a of the body 3. A winding spool 4 which is gripped and transported by a gripper 108 is housed into another film housing chamber 3b of the body 3 when the body 3 arrives at the station C. The camera cover 5 transported by a hanger 109 is adhered to the body 3 assembled in the station C, by which a finished product 6 is formed in the station D. The camera is efficiently produced in this way.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a manufacturing system for a film-integrated camera.

(Prior art) Recently, film-integrated cameras (so-called disposable cameras) have been introduced in which the film is pre-built into the camera body and the film is developed without removing the film after shooting.
It's out there.

Unlike regular cameras, this type of camera does not rewind the film after shooting, but sends it for development without rewinding the film. There is no need to use film with a cartridge as used in other cameras, and the cost is reduced accordingly, which is advantageous.

Therefore, when manufacturing this kind of film-integrated camera using film without a cartridge, the film is wound around a spool in advance, or wound in a hollow or bull-wound state without a spool, and then the film is mounted on the camera in that state. It is more advantageous to store the film in the main body's film storage chamber, or to fully roll it to reduce component costs.

The method and means for producing a bull-wound film are proposed in the patent application ``Film Winding Apparatus'' filed on the same day, so please refer to them if necessary.

Therefore, it is desired to develop a system for manufacturing a film-integrated camera using such a rolled film.

(Object and structure of the invention) The present invention has been made in view of the above points, and an object of the present invention is to provide a manufacturing system for a film-integrated camera using a roll-wound film. , a system in which unexposed long film is wound and cut, loaded into the film storage chamber of the camera body via a holding means that holds the fully wound film, and then a cover is attached to the camera body. It was configured as

(Example) The present invention will be explained below based on the drawings.

FIG. 1 is a perspective view of a manufacturing system for a film-integrated camera according to the present invention. In this manufacturing system, the entire system is a dark room because unexposed film is handled.

The central element of the manufacturing system is the work turntable 1. This working turntable 1 rotates intermittently in the direction of the arrow at a constant speed, and has four stations A, B, C, and D at positions shifted by 90 degrees, and station A is equipped with a camera. The main body 3 is supplied, and the rolled film 2 is supplied to station B, where either the film 2 or the camera body 3 is automatically incorporated to manufacture the camera.

First, the formation of a fully wound film will be explained.

A long unexposed film 100 with perforation formed along both side edges is wound around a frame F, and from here the film 100 is passed through several guide rollers 101.
The steps are repeated to wind up the film using the full winding machine 102. An printing device 103 is provided in the middle of the film 100 for printing frame numbers called frame printing and printing the type of film. This bull winding machine 102 is schematically shown in FIG. 2 and will be described below.

``Wound'' - The edged film 100 is cut by the cutter 105 with its slightly rear end pressed against the guide roller 101 by the roller 104, and then the holding tool 10 waits.
6, the outer circumferential surface is clamped. The clamping tool 106 rotates 180 degrees and turns the film 2 upside down before the double-wound film 2 is conveyed to station B of the turntable 1.

On the other hand, the camera body 3, which has been integrally molded in advance, is supplied to station A of the turntable 1 at a certain timing by a conveyor 107. This camera body 3 is formed with a film storage chamber 3a and a film winding chamber 3b.

Since the turntable 1 rotates intermittently in the direction of the arrow,
At the timing when the camera body 3 supplied to station A reaches station B, the bull-wound film 2 waiting on station B comes down and the camera body 3
The film is stored in the film storage chamber 3a.

When the camera body 3 containing the winding film 2 reaches the station C, the winding spool 4 that has been gripped and conveyed by the gripper 108 is stored in the other film winding chamber 3b of the camera body 3. . When the take-up spool 4 is stored in the take-up chamber 3b, the free end of the fully wound film 2 previously stored in the film storage chamber 3a is joined to the take-up spool 4 by adhesive tape or locking claws. .

At station D, the camera cover 5 carried by the hanger 109 is placed over the camera body 3 assembled at station C, and is glued or welded to the camera body 3 to form a finished product 6. The completed camera product 6 is conveyed from the turntable l by a belt conveyor 110.

The manufacturing system according to the present invention has been described above, and now the bull winding forming machine 2 will be explained with reference to FIG. 2.

The bull winding forming machine 102 includes a collet chuck 102a that can be divided into three parts in the longitudinal direction, and this collet chuck 102.
A flexible leaf spring 102c is fixed to one piece 102a of the collet chuck 102a, which is divided into three parts. The tip of this leaf spring 102c is bent along the surface of the collet chuck piece 102.

The collet chuck 102a is configured such that when a rod moving back and forth in the axial direction inside the casing 102b cuts into the collet chuck 102a, the three pieces separate from each other.
When the rod is retracted, the three-part pieces 102a, 10
2a2, 102a: + becomes one.

To wind the film, as shown in FIG. 2, the leading end of the long film 100 is held between the leaf spring 102c and one of the three pieces 102a, as shown in FIG. When 102a is expanded, film 1
One end of the collet chuck 102a is coupled to the collet chuck 102a.

Then, when the collet chuck 102 is rotated at high speed in the direction of the arrow by a drive source such as a motor (not shown), a film is wound around the collet chuck 102.

After a predetermined amount of the film 100 is wound around the collet chuck 102a, the collet chuck 102a can be easily removed from the wound film by reducing the diameter of the collet chuck 20. Of course, before removing the wound film from the collet chuck 102a, the film is clamped from the outer periphery using the clamping tool 106 shown in FIG.

(Effects of the Invention) As explained above, in the present invention, after winding an unexposed long film, the film is cut and the core is pulled out, and the unexposed film is wound through a holding means that holds the roll-wound film in a roll-wound state. A film-integrated camera can be efficiently manufactured using a double-wound film by loading the film into the film storage chamber of the camera body and then attaching a cover to the camera body.
