Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a production control method for photosensitive materials in which the photosensitive materials are appropriately packaged with packaging materials corresponding to the set type, variety, size, sensitivity, etc. It is something.

In the packaging process, the processed photosensitive material is packaged with a packaging material that corresponds to the type, quality, size, sensitivity, etc. of the photosensitive material. The label displayed on the packaging material is made to match the photosensitive material. By the way, the type, quality, size, sensitivity, etc. labels attached to photosensitive materials are made by printing and cannot be distinguished by final development. Therefore, it is not possible to perform continuous processing, which requires a lot of time to change types, and there is a risk that different types of photosensitive materials or packaging materials may be mixed in. There is a need for a proposal for a method to easily and reliably prevent this. .

The present invention was made against the background of the above, and its purpose is to imprint a side mark corresponding to the identification mark of the packaging material on the photosensitive material during the packaging process, and to mark the identification mark of the supplied packaging material. A photosensitive material production control method that automatically inspects and confirms photosensitive materials, easily and securely packages photosensitive materials with predetermined packaging materials, prevents mixing of different types of photosensitive materials or packaging materials, and further improves quality control efficiency. It is on offer.

In order to achieve the above-mentioned object, the present invention attaches identification marks such as type, quality, size, sensitivity, etc. that can be read by a sensor to each packaging material in advance in the packaging process of photosensitive materials. A production control method for photosensitive materials in which a side mark corresponding to the photosensitive material to be read is imprinted and an identification mark on the supplied packaging material is verified, and packaging is performed using a packaging material that is compatible with the set photosensitive material. It is characterized by

Hereinafter, embodiments of the present invention will be explained in detail based on the accompanying drawings.Firstly, the production control method of disk film shown in FIGS. 1 to 3 will be explained. Identification marks such as type classification codes or numbers that identify quality, size, sensitivity, etc. that can be read by a sensor in advance on the material (hereinafter referred to as classification number)
I have attached.

Then, a label 1 with a classification number corresponding to the classification number given to the packaging material is attached to the cartridge using a cartridge assembly machine (not shown) (Step A).

The production control computer reads the classification number on label 1 of this cartridge, automatically switches the side mark, and burns the side mark corresponding to the classification number onto the film (Step B).

Then, the cartridge collection is automatically switched to collect the cartridge assembly (step C). The production management computer resets the classification numbers for each of the supplied packaging materials, such as moisture-proof paper, cartons, protectors, and outer boxes, and automatically cross-checks the classification numbers of the packaging materials in each packaging process ( D process).

The format of the classification number of label 1 in step A is the application of manufacturing unique number 2 as shown in Figure 2, or the application of a hidden barcode 3 imprinted label with infrared (ultraviolet) ink in the empty space, etc. is possible. Film classification number is 00…SAKURA
HR, 01…SAKURA UHR, 02…SAKURA
It can be replaced with two digits of Arabic numerals such as SHR...

Further, this classification number is specifically expressed by a bar code or the like. Note that the content can be subdivided by increasing the number of digits of the category number. These must be readable with an optical barcode sensor or the like. Further, a label 1 may be applied to the cartridge using a jet air type labeler, a roller type labeler, or the like.

To imprint the side mark on the film in step B, the classification number of the pasted label 1 is read (discriminated) at the position corresponding to the imprinted film using a sensor that corresponds to the format, and the content is determined. Automatically burn in side marks. Side marks are used by photosensitive material manufacturers to record information necessary for production control, such as brand name, product type, etc., by exposure outside the effective screen.

As the sensor, an optical barcode sensor is used, which has a detection performance compatible with the printing and ink of the classification number. If the sensor itself does not have a scanning function, scan it mechanically. The arithmetic processing unit of the production control computer, which consists of a microcomputer, converts the detected value of the sensor into brand name, product type, etc., and sends an interpretable classification number signal to the burning control device, which automatically switches the burning process. have them do it.

To collect the cartridge assembly in step C, read the classification number of label 1 already pasted on the cartridge, or use the shift information of the classification number on the production control computer to collect the cartridge on the collection pallet corresponding to its contents. Sort and store assemblies. The sensor used here is the same as that used for burning the side marks onto the film. For collection pallets, shelves with partitions are used to allow them to be stacked in alignment so that they can be easily supplied in subsequent processes. The collection mechanism uses a manipulator or the like with electrical control so that only the cartridge assemblies corresponding to the classification number can be stored on the pallet. Furthermore, depending on the structure and responsiveness of the manipulator and the pallet supply device, collection into multiple pallets is also possible through automatic switching.

The automatic checking and packaging of the cartridge assembly to the category number in step D includes displaying the category number by the category number and the base color of the moisture-proof paper, displaying the category number by barcode 5 shown in FIG. 3 of the carton 4, Packaging is performed while checking the correspondence between the classification number indicated by the base color of the protector and the classification number of the outer cardboard box. If this verification does not match, it will be automatically excluded, and if the verification matches, it will be classified and sorted by the same category number.

This makes it possible to completely prevent the mixing of different products when packaging the same product by checking all products. Furthermore, by arranging a plurality of packaging material supply devices in parallel, it is possible to simultaneously process a plurality of products. The classification number based on the base color is stamped on areas that do not interfere with the design using a color code such as black...0, brown...1, red...2, etc. Displaying multiple digits of the classification number is done using a combination of multiple colors.

Color discrimination is performed using a reflective optical sensor that has an incandescent bulb in the light emitting section and red, blue, and green filters in the light receiving section. Furthermore, when the type of packaging material does not matter, a limited number of colors other than these can be used, and discrimination can be made using a reflective optical sensor without a filter.

In addition, there is also a method of displaying the classification number on the packaging material using a bar code similar to the above-mentioned label 1.

Fig. 4 shows an embodiment in which the present invention is applied to a 135 size roll film, in which a classification number is set on the printer drum or negative under the control of a production control computer, and side marks and DX marks are placed on the roll film. Burn the latent image barcode. Then, in the packaging process, the classification numbers are reset, and the classification numbers of the supplied patrone bodies, color-coded cartridge caps, brand names of resin can caps, and carton classification numbers are verified. The setting of printer drum or negative classification numbers and the collation and confirmation of the classification numbers of each packaging material are performed in each individual process, but they can be automatically set using a production control computer and can be collated and confirmed in an integrated manner. You may also do so. This embodiment can be similarly applied to 110 and 126 size photosensitive materials.

As described above, according to the present invention, identification marks such as type, quality, size, sensitivity, etc. that can be read by a sensor are attached to each packaging material in advance, and the identification marks are read and a corresponding side mark is imprinted and processing classification is carried out. At the same time, all the supplied photosensitive materials are automatically inspected and confirmed, thereby ensuring prevention of mixing of different types and streamlining production management.

In addition, by using a production management computer to control the entire system of the production management method and shifting information on identification marks to the packaging process, the exchange of production information in related processes involving humans can be significantly reduced. Production management can be made faster and more accurate.
