Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a photographic film processing method in the manufacturing process of processing a long roll film coated with a photosensitive emulsion and dried.

The processing and packaging process for a long roll film after emulsion coating and drying generally includes slitting (hereinafter referred to as cutting), perforation, marking of side marks including side lines or piece numbering, cutting to a fixed length, cartridge printing, etc. It consists of various sub-processes such as winding the film into a cartridge, packaging each product one by one, and logistics packaging for storing the product in a cardboard box.

Usually, dedicated processing machines are prepared for each of these partial processes, each machine can be operated independently, and products are delivered to each machine according to the progress of the work. Taking 35mm cartridge film as an example, the process can be divided into the following steps.

Cutting process: Shred into 35mm narrow pieces using a cutting machine and roll up.

Perforation and side line/side mark burning process on the shredded narrow-width film: perforations are made on both ears using a perforation machine, and side marks and side lines are burned in.

Komayaki process: The piece number is burned in using a winding machine.

Cutting to a specified length and winding process: Cut to a specified length, process the shape of the leader part, wind it into a cartridge, and close the cap to produce the product.

Product packaging process: The product is placed in a resin can and sealed in a carton along with the instructions for use.

Logistics packaging process: 10 cartons are wrapped in cellophane, and then 100 to 200 cartons are wrapped in a cardboard case.

In the above process, it is possible to work in bright light after the product packaging process, but since the photosensitive film is exposed in the process before wrapping, the process must be done in the dark, and the equipment must be covered with a light-shielding cover or the entire work area must be darkened. Workability is extremely poor. In this type of work, using the cutting machine, perforator, komasaki machine, winding machine, etc. as independent machines to perform partial processes increases the amount of in-process inventory, resulting in an increase in stock space, and increases the cost of partial processes. There are many inconveniences, such as increasing the administrative burden of goods delivery and other administrative tasks. Also, repeating winding and unwinding for each process is
This poses many problems such as charging and scratches on the film surface.

An object of the present invention is to provide a simplified method for processing photographic film. A second object is to provide a photographic film processing method for perforating a wide, long roll film and then cutting it into narrow widths, and further to provide a processing device that integrates dark working steps.

The above object of the present invention is achieved by a photographic film processing method characterized in that perforation and/or display burning is performed in the process of cutting a long film. That is, in the process of cutting a wide long film into narrow widths, a large number of small perforation holes are punched at once while keeping the width wide, and the burning process is performed simultaneously, resulting in even faster processing. can be done.

Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 shows a perspective view of an embodiment of the present invention, in which a long roll film is perforated with a large number of punch dies in its wide width state, and then side marks and side lines are burned. After this process, it is cut into pieces of 35mm width and rolled up.

In the figure, the original roll F1 is unwound and the web F2
The perforations are made by punch-die units 11a and 11b that perform meshing operations while moving in synchronization with the movement of the punch-die units 11a and 11b. Although a punch die is used in the drawing, a normal rotary punching machine may be used.

Next, in the burning section 12, side marks, side lines, etc. S1, piece numbers S2, etc. are burned in.
Although the printed characters are shown in the figure, they are actually latent images. The wide web F2 that has been burned is processed by a slitting device 1 using a rotary cutter or the like.
3 and 13' are used to cut the film into 35 mm width strips, and the individual narrow width films are wound up using winding devices 14 and 14'.

Here, various methods can be considered for punching perforations while moving in synchronization with the running of the web F2, such as a rotary punching machine, but the punch-die unit will be described in detail.
Figure 2 shows the punch die unit for perforating the web F.
FIG. 2 is a cross-sectional view taken along the axis of FIG.

Sliding guide 21 fixed to the frame of the device
A, 21b, 22a, and 22b, the horizontal slide rods 23 and 24 are designed to be able to slide in the forward and backward direction of film travel. This horizontal slide bar 23,

is equipped to be able to slide up and down perpendicular to the film surface. The punch unit 11a is the slide guide 2
7a and 27b, the die unit 11
b slides on slide guides 28a and 28b.

Punch unit 11a and die unit 11b
Cam floors 29a and 29b are respectively disposed, and these move along the grooves of fixed groove cams 31a and 31b fixed to the apparatus frame, thereby defining the loci of movement of the punch unit 11a and die unit 11b.

A small number of pilot punches 111a and a small number of hole punches 112b are installed in the punch unit 11a, and a die hole 110b that engages with the pilot punch 111a and the hole punch 112a is bored in the die unit 11b.

FIG. 3 is a partially enlarged view of the fixed groove cams 31a and 31b. The fixed groove cams 31a, 31b have outward paths 311a, 311b and return paths 312a, 31, respectively.
2b, movable auxiliary guides 32a and 33a are provided at the junction of the outgoing path 311a and return path 312a on the punch unit 11a side, and movable auxiliary guides 32a and 33a are provided at the junction of the outgoing path 311b and the return path 312b on the die unit 11b side. The auxiliary guides 32b and 33b are mounted while being biased in the direction of the arrow by a spring or the like (not shown).

As shown in FIG. 2, the cam floors 29a and 29b are designed to move forward and backward in cooperation while always maintaining corresponding positions in the upper and lower directions. First, the cam floors 29a and 29b are guided by auxiliary guides 32a and 32b at the branching portion, respectively, to the outward path 31.
1a and 311b, and become the relative positions of 29a and 29b.

At the confluence section, cam floors 29a, 29b
, the auxiliary guides 33a and 33b are pushed up and down to reach the relative positions of the end points 29a and 29b.

In the return movement of the cam floors 29a and 29b,
The return path 312a, 3 is guided by the biasing spring to the auxiliary guides 33a, 33b in the posture shown by the solid line.
12b and becomes the relative position of 29a and 29b.

Then, the cam floors 29a, 29b push down or flip up the biasing springs of the auxiliary guides 32a, 32b, and the cycle is completed to the initial position relative to the cam floors 29a, 29b.

The operation of the drilling device shown in FIG. 2 equipped with the fixed groove cams 31a and 31b described above is as follows.

That is, a lateral reciprocating force is applied to the arm 41 biased against the lateral slide rod 24 by a drive device (not shown). At this time, when moving to the right (forward movement), the speed of the system is first synchronized with the running speed of web F2 in the acceleration section A in Figure 3, and the speed of the system is sent at the same speed as the running speed of web F2 in the punch section I. It is necessary to stop the system in the (c) deceleration section and return it as quickly as possible in the (d) fast-return section, and this operation is possible with some known methods and devices.

As a result, the horizontal slide rod 2 forms an integral rigid body.
3, 24, and the vertical slide rods 25, 26 perform reciprocating motion in the horizontal direction, and at this time, the punch unit 11a and the die unit 11b move against the vertical slide rods 25, 26.
The cam floors 29a, 29b perform horizontal reciprocating motion together with the grooved cams 31a, 31b.
Since it is engaged with the grooved cam, the travel path is regulated by the grooved cam, and it also moves in the vertical direction during forward movement.

Since the vertical relationship between the punch unit 11a and the die unit 11b is strictly controlled by the vertical slide rods 25 and 26, during forward movement, the pilot punch 111a and the perforation punch 112a punch through the traveling film and enter the die hole 110b. Insert and perform drilling operation.

When drilling, the pilot punch 111a locates several holes at the rear of the perforation drilled in the previous operation, inserts the pilot punch 111a into the perforation in advance, and then performs the drilling with the perforation punch 112a. It will not upset the Horatio Pitch. Further, it may be necessary to slightly modify the running condition of the film web F2 in conjunction with the pilot punch 111a, but this can be done by using a known web running control method using dancer rollers or the like.

The perforation device used in the long film cutting process of the present invention has been described above.

The present applicant has already proposed several inventions and ideas regarding the display burning device used in the long film cutting process of the present invention. In other words, a patent application issued in 1973 for performing synchronous burning while transporting the film using a flash light source.
The device proposed in the specification of Japanese Utility Model No. 160532 or Japanese Utility Model Application No. 119495/1986 can be immediately incorporated and applied. Further, a method of display burn-in using a CRT can be incorporated and applied to the apparatus of the present invention.

The photographic film processing method of the present invention described above reduces the number of times of winding and unwinding of a long film, which was conventionally performed, and perforates or burns the film in the form of strips. Therefore, when using the method of the present invention that interlocks and integrates as shown in Figure 1, it reduces intermediate work-in-process inventory and the space for it, shortens process transit time, and simplifies goods delivery work between subdivision processes. This is a new invention that has the effect of greatly improving productivity, such as reducing the number of operators, eliminating logistics between process equipment, and reducing the number of operating personnel.
