Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a film mount device for loading a long roll of developed film one frame at a time into a mount frame.

[Conventional technology]

Generally, long developed films such as reversal film are loaded one frame at a time into a mount frame in order to efficiently perform slide projection, improve the efficiency of editing, and facilitate efficient storage and inspection. Conventionally, this has been done manually, or in simple models, it has been supplied by hand.

For this reason, as disclosed in Japanese Patent Publication No. 57-22373, a film mount device has been developed which automatically loads cut film into a mount frame one frame at a time.

This film mount device has a stock mechanism that stacks and stores a mount frame in which the main plate and sub-plate are folded in half, three sides are joined and closed, and one side is left open. a mount frame setting mechanism for pushing out the lowermost mount frame to place it in the film loading section; a film feeding mechanism for feeding out the set developed film one frame at a time; and a film feeding mechanism for cutting the developed film frame by frame. a film cut mechanism; an opening pry opening mechanism consisting of a pair of wedge members that temporarily pry open the opening of the mount frame pushed out by the film loading section from the sides of the opening; A film loading mechanism is provided for loading the cut film into the pocket of the mount frame through the opening thereof by pushing the cut film with the leading end of the film to be cut next and passing it between the pair of wedge members.

[Problem to be solved by the invention]

However, since this film mount device uses a mount frame in which the main plate and sub-plate are closed together, a separate mount frame closing device must be provided, and it is not fully automated. It is difficult to perform the work continuously and efficiently, and in order to insert the cut film through the opening of the mount frame, the opening must be temporarily pried open from the sides using a pair of wedge members, so the mount frame is There is a risk of damage to the sides.
Furthermore, although the opening closes due to the self-healing power of the main plate and sub-plate after the film is loaded into the mount frame, there is a risk that the loaded film may fall out due to a gap created by temporarily prying it open. Therefore, it is necessary to glue the opening, and furthermore, when loading the cut film into the pocket of the mount frame, the tip of the film to be cut next moves, so the contact between the film and the film becomes difficult. The contact part may be deformed.

The present invention was invented in view of the above points, and
The purpose is to create a film mount device that can automatically, continuously, efficiently and reliably perform the mounting process of cutting a long length of developed film one frame at a time and loading it into a mount frame. It is about providing.

Next, the configurations of the mount frame stocking mechanism C of the group, the mount frame feeding mechanism D for feeding out the mount frame, and the mount frame pressure bonding mechanism E will be explained.

The mount frame stock mechanism C has mount frames 1 stacked on the lower side of the mount transport path, and the mount frame 1 is stocked by a mount frame set mechanism as shown in FIG. mount frame 1 is placed. That is, the stock of the mount frame 1 housed in the container 31 is
It is pushed up by a spring 32 compressed between the support stand 31a and the bottom of the container 31 and locked by a stopper (not shown), and the uppermost mount frame 1 is placed in the film loading section.

The top mount frame 1 set like this
When one frame of film 5 is fed out by the film feeding mechanism A and its leading edge enters the dovetail groove 7 of the mount frame 1 from an oblique direction, the film 5 is rotated by the motor 33 via a transmission mechanism such as a change gear or a gear belt. The pin joint 29 of the upper blade 27 is pushed by the protrusion 35a of the cam 35 fixed to the single shaft 34,
One frame of the film 5 is cut by swinging the upper blade 27.

The mount frame sending mechanism D is equipped with another cam 36 fixed to the first shaft 34, and an actuator 38 of a micro switch 37 is attached to the periphery of the cam 36.
The recess 36 formed on the peripheral edge of the cam 36 is in contact with the
When the actuator 38 rides on the circumference from a, the film feed motor 25 rotates, and the stop lever 39 of the mount frame 1 is rotated, and the uppermost mount frame 1 is released from the lock in the transport direction and rotates. The mount frame 1 is attached to the convex portion 35a of the cam 35.
is configured to be pushed out. Note that other cams may be used to push out the mount frame 1.
When the actuator 38 is in contact with the peripheral edge of the cam 36, the feed motor 25 is rotating.

The mount frame crimping mechanism E includes gears 41 and 4 at both ends of a roller 40 that is horizontally suspended on the uppermost mount frame 1.
1 is fixed and rotated by a second shaft 42 which is rotated by a motor 33 via a transmission member, and a gear 44 is rotated via a gear 43 meshing with one gear 41. One end of a shaft 45 is eccentrically attached to the gear 44, and the other end of the shaft 45 is in contact with a lever 47 provided integrally with the gear 46. gear 4
6 is meshed with a gear 48, and a lever 49 provided integrally with the gear 48 is provided with a mount frame bending rod 50 extending to the conveyance path. 5
1 is a return spring that reverses the gear 46 and returns it to the initial position. Further, at the final end of the conveyance path, pressure rollers 52 and 53 are provided that are rotated by a third shaft 51 that is rotated by a motor 33 via a transmission member.

Next, the operation of this device will be explained with reference to the basic electric circuit diagram shown in FIG.

This device is basically driven by a built-in battery, but it can also be used with a household 100V power source by attaching an adapter.

First, when the power switch 54 is turned on, the film illumination lamp 11 is turned on. Then Patrone 1
3, pull out the film 5, reveal the starting frame position, and set it at a predetermined position. Then, the user presses the push button 30 and uses the upper blade 27 to cut off the excess end portion of the film 5 where the image is not taken. Then motor 3
3 to rotate the first to third shafts 34, 42, and 51. and the first axis 3
When the actuator 38 of the micro switch 37 rides on the circumference above the concave portion 36a of the cam 36 of No. 4, the micro switch 37 is turned on, thereby causing the film feed motor 25 to rotate. This rotational force is transmitted to gear 18 via gears 24 and 23, and rotates cam 19 and sprocket 16.

The rotation of the cam 19 pushes the actuator 21 of the micro switch 20, turning the micro switch 20 on. At the same time, the sprocket 16 feeds the film 5, and when one frame of film has been fed, the tip moves from the stock position to the dovetail groove provided in the main plate 2 of the uppermost mount frame 1 which has already been set to the mount position. Inserted into 7.

When this film is fed by one frame, the actuator 21 engages with the recess 22 of the cam 19 and the pressure is released, so the micro switch 20 is turned off and the first shaft 34 is rotated by the motor 33. The convex portion 35a of the cam 35 rotates the upper blade 27, thereby cutting one piece.

The mount frame 1 containing one frame of film 5 that has been cut in this way is pushed out by the convex portion 35a of the rotating cam 35, and is conveyed by the shaft 40 that rotates by the second shaft 42. , when the sub-plate 3 is positioned on the mount frame bending rod 50 as shown in FIG.
The gear 46 rotates via the gear 44, and the gear 48
The bending rod 50 rotates counterclockwise as shown in Figure b.
At this time, the mount frame 1 is bent at the hinge part 4, folded in half, and attached to the pressure roller 52, as shown in FIG. 7c.
Leads between 53. The mount frame 1 is then held between the pressure rollers 52 and 53, and after the pressure is securely bonded, the mount frame 1 is discharged from the apparatus.

Alternatively, a film number counter 56 may be placed at a suitable location and a counter switch 57 may be operated to count the number of mount plates.

Further, if a defective frame is found among the film frames during the above-mentioned operation, it is discharged as follows. That is, when a defective frame of the film 5 is discovered by the illumination of the film illumination lamp 11 during mounting, the stop switch 58 of the motor 33 is activated, the good frame that has been sent so far is mounted, and the motor 33 is stopped. . Thereafter, the push button is pressed to turn on the micro switch 37 and start the film feed motor 25. As a result, the film feed motor 25 is stopped after feeding one defective frame of the film 5 by the action of the micro switch 20 or the photodetection element T. Then, the film 5 is cut by actuation of the push button 30, and then, if the film is of good quality, the starting switch 55 of the motor 33 is operated to enter automatic operation again.

The embodiment shown in FIG. 9 is for explaining another embodiment of the mount frame bifold mechanism in the second group. 1a, and a second arm 6 having a mount frame bending rod 62 that supports the lower part of the sent-out mount frame 1.
1b and a third arm 61c that latches a spring 63 that rotates the lever 61 counterclockwise in FIG. At the point when the mount frame 1 protrudes to the right in FIG.
a comes into contact with the mount frame 1 while pushing it.
advances, and the bifold lever 61 is activated by the spring 63.
9, the mount frame bending rod 62 of the second arm 61b moves upward in a circular motion to fold the mount frame 1 in half and guide it to the pressure rollers 52 and 53. That's what I do.

〔Effect of the invention〕

As described above, in the present invention, the mount frames stacked with the main plate and the sub-plate opened in the stock mechanism are pushed up from the lowest part by the mount frame set mechanism, and the uppermost mount frame is placed in the film loading section. On the other hand, the set developed film is fed out frame by frame by the film feed mechanism, cut frame by frame by the film cut mechanism, and the cut film is placed in the mount frame with the sub-plate open. After the mount frame is inserted into the pocket of the main plate, the stopper means that locks the movement of the mount frame in the transport direction is released, the mount frame is sent out by the cam means, and the sub plate of the sent out mount frame is ,
The main plate is folded in half by a bending rod that rotates in synchronization with the movement of the sent-out mount frame, and the folded sub-plate is pressed onto the main plate by roller means and loaded into the mount frame. , there is no need to provide a separate mounting frame closing device, the mounting work can be completely automated, and can be carried out continuously, efficiently and easily, and
When operating the screen, dirt from your hands does not stick to the screen, allowing you to finish it neatly.
