2. Description of the Related Art A large number of raw materials (liquid, powder (solid)) are used for producing photographic light-sensitive materials. Further, in order to produce one kind of photographic light-sensitive material, particularly color photographic light-sensitive material, at least 50 kinds of raw materials are required. In addition, in response to diversifying user needs in recent years, there are many types of color negatives and color papers, and many common raw materials are used.
There are also unique ingredients used in each variety,
The total number is 100 or more. In the case of a solid material, such various raw materials are mainly weighed with a balance and, if necessary, added to a tank prepared and used as a liquid chemical or the like.
The liquid raw material is used by measuring its volume or weight and diluting it to an appropriate concentration for use, or by mixing it with various chemicals and dissolving it in an appropriate solvent such as water or an organic solvent.

Such raw materials have the following characteristics and are diverse. There are many types. As mentioned above, at least 50 types of raw materials are used for one type, and at least 100 types of raw materials are used for the entire plant. Wide measurement range Even with one raw material, the measurement range is changed each time due to the lot scale, and the usage amount of each raw material is different for each raw material. The raw material has a wide variety of shapes. There are various types of raw materials such as liquid, wax, and powder, and among them, physical properties such as viscosity and shape are different depending on the chemical. Storage conditions are different Depending on the raw materials, there are problems of quality stability, such as storage in a cool and dark place, storage in a refrigerator, storage in a light-shielded state, and storage under controlled temperature and humidity.

Some of these raw materials are dangerous to handle by hand, such as deleterious substances and dangerous substances. In such special cases, automated equipment is introduced to automate operations such as weighing and addition. is doing. In addition, automated equipment such as automatic air blowing and automatic weighing is used for powdered gelatin, etc., which is used in a very large amount and is difficult to carry manually, but such cases are only a few. As mentioned above, in order to produce photographic light-sensitive materials, it is necessary to use an extremely large number of raw materials, 50 or more, and to prepare these raw materials each time according to the lot scale of various products. For this reason, full automation requires complicated equipment and is difficult to realize. Therefore, most raw materials are currently handled by hand.

[0005]

Many mistakes have occurred when humans handle such raw materials. Analysis of the frequency of such mistakes revealed that there was one tendency. 1) Mistakes in raw material names Since a large number of raw materials are handled, mistakes occur due to misunderstandings by workers. Although a double check error prevention measure is applied as a means for preventing this error, it does not completely prevent the error. 2) Weighing mistakes When measuring raw materials (weight measurement, volume measurement), there are mistakes such as mistakes due to misunderstanding and mistakes in reading work instruction values. Although a double check error prevention measure is applied as a means to prevent this error, it does not completely prevent the error. 3) Wrong input Even when the weighed raw materials are put into the specified tank, etc., the instruction sheet may be wrong, or may be wrong due to misunderstanding.
There is a mistake to make a mistake in similar raw materials. Although a double check error prevention measure is applied as a means to prevent this error, it does not completely prevent the error.

[0006] An object of the present invention is to develop and put into practical use a system for supporting the prevention of mistakes due to manual work against the background of the present situation.

[0007]

At the weighing station, the identification code reader 2 reads the identification code attached to the raw material container and having information on the raw material in the container. Based on the raw material information read by the identification code device 2 and the chemical preparation information stored in the chemical preparation information storage device 3, the raw material determination means 6 confirms the quality information such as the raw material name, the batch information and the expiration date, and the desired information. Determine whether there is no problem in using it for preparing the chemicals for the light-sensitive material.
The determination result is output by the output device 10. However, a display or the like may be used as the output device, or a device that visually or audibly informs, such as a lamp or a buzzer, may be used. The lamps of different colors may blink or the tone of the buzzer may be changed depending on whether there is a problem or a problem.

In the case of "no problem", subsequently, the instruction information generating means 7 selects the optimum weighing instrument to be used for weighing based on the raw material information and the drug preparation information, the target weighing value, and further the weighing. The storage conditions (specifically, the storage location and temperature / humidity conditions at the time of storage) for storing the subsequent raw materials until they are put into the chemical preparation tank are determined, and the output device 4 is used as the measurement instruction information.
And output it to the operator. As an output device, for example, by equipping each weighing instrument with a device that visually and audibly informs, such as a lamp or a buzzer, by turning on a lamp provided in an optimal weighing instrument or ringing a buzzer,
The operator can be informed of the weighing machine to be used. The target measurement value and the like are preferably displayed on a display device such as a display.

When the worker weighs the raw material in accordance with the weighing instruction information, the weighing value judging means 8 compares the weighing value output from the weighing device with the target weighing value, and the weighing value is determined with respect to the target weighing value. It is determined whether the value is a correct value within the error range, and the determination result is output by the output device 11. The allowable error range for each raw material is included in the drug preparation information in advance. Weighed raw materials are stored in a special container. The worker attaches to this container an identification code having the information output from the identification code output device 9 and the information indicating that the raw material in the container has been weighed in addition to the raw material information, and the medicine preparation tank To the loading station. If the product is transported immediately after weighing and is not put into the chemical preparation tank, the weighed raw materials are temporarily stored according to the storage conditions indicated in the weighing instruction information.

At the loading station, the identification code attached to the container containing the weighed raw materials is read by the identification code reader 2. As in the case of weighing, it is confirmed whether the raw material determination means 6 has no problem in using it for preparing a desired chemical for a photosensitive material, and further it is confirmed that the raw materials have been measured, and the determination result is output to the output device. 10 to output. Then, the instruction information generating means 7 selects the medicine preparation tank to be charged, determines the charging time, outputs it as the charging instruction information from the output device 4, and informs the operator. As an output device, preferably provided with a device for visually and audibly notifying such as a lamp or a buzzer for each chemical preparation tank, by turning on the lamp provided in the corresponding chemical preparation tank or by sounding a buzzer, After notifying the chemical preparation tank to be charged, the worker carries the container and waits in front of the corresponding chemical preparation tank. At the time of throwing in,
Similarly, when a worker is informed of the time of introduction by turning on a lamp provided in the corresponding chemical preparation tank or sounding a buzzer, the operator manually and / or inputs the raw materials into the chemical preparation tank by means of an auxiliary supply means. To do.
