DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a collective package for photosensitive material according to the present invention and individual packages constituting the collective package according to the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a view showing a pillow-package type collective package in which five individual packages containing resin cans are integrated as an example of the collective package for photosensitive material of the present invention. In the figure, (a) shows the front side of the pillow package, (b) shows the back side, and there is an expiration date display section on the back side, where the expiration date is printed in a printing form different from the printing of the packaging material. ing. A patrone containing a photosensitive material film is contained in the resin can contained therein.

FIG. 2 is a view showing an example in which an expiration date is displayed on a cartridge in which a photosensitive material film is stored. 1 denotes a patrone main body, 2 denotes a patrone body, 3 denotes a spool, 4 denotes an upper side, 5 denotes a lower patrone cap, and 6 denotes a tongue end of a photosensitive material film. The expiration date may be indicated on the tongue end of the film 6 or on the upper cap 4 or the patrone body 2 in FIG.
The expiration date may be displayed as follows. When the patrone indicating the expiration date is put in a resin can as shown in FIG. 3, the material of the resin can body and the resin can cap of FIG. Since the portion has better transparency, it is desirable to print on the upper patrone cap portion 4 which can be seen from the resin can cap portion from the viewpoint of recognition.

As a method of displaying the expiration date, printing by an ink jet method, a laser printing method or a tampo printing method, or a perforation method in the case of a film tongue end may be used.

FIG. 3 is a diagram showing an example in which the expiration date is displayed on the resin can. Reference numeral 10 denotes a resin can housing a patrone housing a photosensitive material film therein, 11 denotes a resin can body, 12 denotes a resin can cap, and 13 denotes a resin can bottom. FIG. 2A shows the expiration date displayed on the resin can body 11 as indicated by 14, and FIG. 1B shows the expiration date displayed on the resin can bottom 13 as indicated by 14. .

As a method of displaying these expiration dates, the above-described printing method by the ink jet method, the laser printing method, or the tampo printing method can be used. In the case of the laser baking method to the resin can, there is a problem that it is difficult to distinguish the resin surface from the surroundings by shaving the resin surface with a laser. It is preferable to perform an ink coating process in advance, and then perform laser baking from above.
In particular, in view of suitability for recycling, it is desirable to use a display method by graining, which does not use impurities such as ink. Here, laser baking on a resin can was described, but the present invention can also be applied to display on other resin parts, such as display on a resin cartridge.

The process of displaying the expiration date on the individual packages constituting the collective package includes a process of slitting the original roll of the photosensitive material film, cutting it, and storing it in a cartridge or a cartridge (also referred to as an interior process). It is preferable to carry out on the same production line. Thereby, it is possible to avoid troubles such as mixing of different types of photosensitive materials or mixing of the same type but manufactured on another day. Further, a step of accumulating the individual packages indicating the expiration date to form a collective package (also referred to as an exterior process).
May be an on-line system in which the above-described interior process is performed on the same line, or an off-line system in which individual packages are integrated and then exteriorized on another manufacturing line.

When the interior process and the exterior process are the same on-line system, the expiration date is printed in two places in the interior process and the exterior process, but the expiration date printed in the interior process before entering the exterior process. Confirm that the expiration date is the same as the expiration date of the exterior process.After performing the exterior process, move to the process of printing the expiration date of the exterior, but if the expiration dates do not match,
It is preferable that the interior component be discharged from the process or the system be stopped.

When the interior process and the exterior process are off-line, the expiration date is already printed on the individual package in the interior process, and the integrated individual package is printed in the interior process before entering the exterior process. After confirming the expiration date with an image processing device, etc., and confirming that all of the plurality of integrated individual packages have the same expiration date, performing the exterior in the exterior process and printing the expiration date for the exterior. Is preferred. If a plurality of stacked individual packages with different expiration dates are mixed, it is preferable to eliminate the individual packages or stop the process. or,
Instead of reading the expiration date displayed on the individual package, there is also a method of printing on the collective package based on the expiration date information attached to a storage container or the like in a manufacturing process in which a plurality of individual packages are integrated and stored. As another method, instead of printing based on the expiration date displayed on the individual package, a method of reading the expiration date of the printed collective package and comparing it with the expiration date of the individual package may be used for production. .

FIG. 4 is a block diagram of a system for printing an expiration date on a resin can of an integrated individual package by an ink-jet method. Reference numeral 20 denotes a controller. When the name of the kind to be packaged is input, the expiration date is automatically calculated from the data on the day of packaging, and the expiration date is set. 2
Reference numeral 1 denotes a printing unit, 22 denotes an ink jet printer, and a controller 20 has a proximity sensor 23 connected via an amplifier, which detects a resin can and sends a command to the printing unit. Is printed on the resin can. The printed individual package can be transferred to the packaging process online as it is, or a method in which the packaged products are collected and then sent to the next packaging process offline may be used.

FIG. 5 is a view showing a state in which the individual package is temporarily stored in a pallet 25 for sending to the next exterior process. The associated expiration date information 26 is displayed on the pallet. In the exterior process, the associated expiration date information is read by the reader 27 instead of reading the expiration date of each individual package, and the information is transferred to the controller. Thereby, it is possible to set the expiration date of the collective package.

FIG. 6 is a schematic diagram of a packaging process in which individual packaging and collective packaging are on the same line. FIG. 1A shows a single controller 20 that controls the printing units 21 and 21 ′ and the inkjet heads 22 and 22 ′ of an individual package and a collective package, respectively, and FIG. A method is shown in which a method is used in which the packaging data and the collective packaging are printed by using independent controllers 20 and 20 ', and comparing and printing the setting data by the comparing means 24.
