DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photosensitive material with a camera loading member for automatically joining a camera loading member to the photosensitive material sheet after cutting the photosensitive material web to obtain a photosensitive material sheet. The present invention relates to a method and an apparatus for manufacturing the same.

[0002]

2. Description of the Related Art A large-sized camera using a photosensitive material sheet, for example, a 4 × 5 inch cut film, employs a photographic film package in which a photographic film unit is freely inserted into and removed from a light-shielding envelope having an opening at one end. I have.

A photographic film unit includes a photographic film sheet and first photographic films attached to both ends of the photographic film sheet.
And a second carrier sheet (camera loading member), and a light-shielding clip is fixed to the first carrier sheet. The light-shielding clip is for closing the opening of the light-shielding envelope to prevent the photographic film sheet from being exposed to external light when the photographic film unit is accommodated in the light-shielding envelope.

[0004] In order to manufacture the above-mentioned photographic film package, for example, a manufacturing line disclosed in Japanese Patent Application Laid-Open No. 7-89501 is known. According to this conventional technique, a sheet supply step of setting a first carrier sheet and a second carrier sheet having a light-shielding clip fixed to the pallet around a conveyor on which the pallet is repeatedly transportably mounted, A sheet connecting step of joining a photographic film sheet to a second carrier sheet, a sheet inserting step of inserting a photographic film unit into a light-shielding envelope, and a collection step of taking out a photographic film package from the conveyor are arranged.

[0005]

However, in the above-described sheet connecting step, usually, a photographic film sheet is formed by cutting a photographic film web wound into a roll into a predetermined length. The film sheet must be positioned with respect to the first and second carrier sheets on the pallet. Therefore, in addition to a mechanism for positioning the photographic film sheet cut to a predetermined length, a mechanism for positioning the photographic film sheet with respect to the first and second carrier sheets on the pallet is required.

[0006] This complicates the configuration of the entire equipment and, in particular, the steps from cutting the photographic film web to obtain a photographic film sheet and joining the photographic film sheet to the first and second carrier sheets. However, it is pointed out that the method is considerably complicated and takes a long time.

SUMMARY OF THE INVENTION The present invention solves this kind of problem, and performs a process from cutting a photosensitive material web to joining a camera mounting member quickly and efficiently.
An object of the present invention is to provide a method and an apparatus for manufacturing a photosensitive material with a camera loading member, which can effectively simplify the equipment configuration.

[0008]

In order to solve the above-mentioned problems, the present invention relates to a photosensitive material web fed to a cutting position, wherein the front side of a separation site is temporarily held by a transfer mechanism. From a cutting step of cutting the photosensitive material sheet to a predetermined length to obtain a photosensitive material sheet, to a step of transporting the photosensitive material sheet to a joining position and joining the photosensitive material sheet and a camera loading member. Thus, once the photosensitive material web is positioned at the cutting position, the transfer mechanism does not need to carry out the work of holding the photosensitive material sheet, so that the work from the cutting process to the joining process can be performed continuously and efficiently. Can be accomplished.

Further, by regulating the width of the front and rear of the separation portion of the photosensitive material web in the width direction at the cutting position, a highly accurate photosensitive material sheet having desired dimensions can be reliably obtained. At this time, the rear side of the separation part of the photosensitive material web is positioned by the fixed guide means, while the front side of the separation part of the photosensitive material web is positioned by the movable guide means. Therefore, when transferring the photosensitive material sheet after cutting,
It is possible to prevent the movable guide means from interfering with the transfer mechanism.

Further, a belt member is provided in front of the separation portion of the photosensitive material web in correspondence with the movable guide means, so that the photosensitive material web is surely damaged when the photosensitive material web is cut. Can be blocked.

Further, the transport mechanism transports the cut photosensitive material sheet to a notch processing position to form a notch in the photosensitive material sheet, and when the photosensitive material sheet is determined to be defective, the photosensitive material sheet The sheet is transported to the discharge position. For this reason, the entire manufacturing operation of the photosensitive material with a camera loading member is more efficiently and automatically performed.
