BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a management apparatus for managing the stock of raw materials when preparing a compound containing a plurality of raw materials, for example, seasonings, dyes, incense sticks, and preparations.

[0002]

2. Description of the Related Art Conventionally, stock management of raw materials when making the above-mentioned compound has been carried out by:
Relies on workers' eyes or memories. However, when there are many types of blends to be made and many types of raw materials for the blends, if management of the stock of each raw material relies on visual observation or memory of the operator, a management error is likely to occur. In some cases, the raw materials may be out of stock.

The present invention has been made in order to solve the above problems, and an object of the present invention is to provide a raw material inventory control apparatus capable of accurately controlling the raw material inventory of a compound.

[0004]

In order to achieve the above object, a raw material inventory management apparatus according to the present invention comprises:
The current stock weight and the minimum stock required for the next formulation
Input means for inputting the required replenishment order weight, storage means for storing the input contents, a weighing machine for measuring the raw materials taken out for blending and outputting the weighed value, and when safety is not out of stock Current warehouse calculation means for subtracting the weighing value from the current warehouse weight to calculate a new current warehouse weight, and updating means for updating the current warehouse weight stored in the storage means with the calculated new current warehouse weight. If, by comparing the new current stock weight and the replenishment orders weight, when the former is smaller, comparing means for outputting a replenishment request signal, it receives the refill request signal, the raw material is the replenishment orders weight or more Refill
Safety out-of-stock display means for displaying safety out-of-stock so as not to start compounding until the safety out-of-stock is started, and writing means for storing safety out-of-stock in the storage means.

[0005]

In the above-mentioned raw material inventory management apparatus, first, the names of the raw materials for making the above-mentioned compound, the current stock weight and the replenishment order weight are input by the input means, and the input contents are stored in the storage means. You. Here, the replenishment order weight is the minimum stock required for the next operation, and is therefore larger than the weight of one raw material taken out.

Then, the raw material is taken out and weighed by the weighing machine, and the weighed value is output to the current storage calculating means. When the safety stock is not out of stock, the current storage calculating means causes the current storage weight of the storage means to be stored. Is subtracted from the above to calculate a new current warehouse weight. The updating means,
The current warehouse weight stored in the storage means is updated with the new current warehouse weight.

The new current warehouse weight is compared with the replenishment order weight stored in the storage means by the comparing means. When the new current warehouse weight is smaller, the replenishment request signal is transmitted to the safety stock. The output is output to the run-out display means, and the worker is notified of the safety run-out of the current warehouse weight, and the worker replenishes the raw material based on the display result of the display means. Further, the replenishment request signal is stored in the storage means via the writing means,
When the work is completed once and the work is performed again, the safety out-of-stock stored in the storage means is displayed on the display means, so that it is possible to prevent the worker from forgetting to run out of the safety stock.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows, as an example of a raw material inventory management device according to the present invention, a device that also performs raw material mixing management for preventing a raw material mixing error. This management device constitutes a computer system, and includes a compound name of a compound composed of a plurality of raw materials, a name and a raw material mixing amount of each raw material, a raw material storage location, a current storage weight of each raw material, and a replenishment order weight of each raw material ( Input means 1 such as a keyboard for inputting the minimum stock required for the next operation), storage means 2, and writing means 3 for writing the contents of the input means 1 to the storage means 2
And reading means 4 for reading the contents stored in the storage means 1.

Further, the management device is provided with the input means 1
When a compound is selected in step 5, a display 5 having a raw material display means 51 for displaying the raw material name and the raw material storage location and a display means 52 for displaying the raw material blending amount, and a raw material storage shelf or storage container are provided. A reading means 6 such as a hand scanner for reading the raw material identification bar code and outputting raw material name read data, and a weighing machine 7 for measuring the raw materials taken out for blending are provided.

The output of the reading means 4 and the output of the reading means 6 correspond to the raw material name read data and the raw material display means 51.
Are input to the raw material coincidence detecting means 8 for detecting that they match, and when the raw material coincidence is detected by the detecting means 8, the mixing amount display means 5
2 indicates the amount of the raw material compounded.
The output of the reading means 4 and the output of the weighing machine 7 are inputted to a blending quantity coincidence detecting means 9 for comparing the measured value with the raw material blending quantity and detecting that the difference is within a certain allowable range. On the output side of the detecting means 9, a step progressing means 10 for displaying the name of the next raw material and the raw material storage location on the raw material display means 51 based on the metering completion signal when the blending amount coincidence is detected. It is connected.

The signal from the input means 1 is also input to the batch control means 11. When a plurality of the same compound are simultaneously prepared, when the batch number is input by the input means 1, the batch control means 11 is operated, and the step progress means 10 is controlled until the batch number is completed. The name of the raw material and the storage location of the same raw material are displayed on the raw material display means 51.

The current storage weight and the replenishment order weight of each raw material set by the input means 1 are previously written and stored in the storage means 2 by the writing means 3. The current storage weight read by the reading means 4 and the weighing value from the weighing machine 7 are input to the current storage calculation means 12, and the weighing value is subtracted from the current storage weight. The output side of the calculating means 12 is connected to an updating means 13 for updating the current warehouse weight stored in the storage means 2 based on the new current warehouse weight.

On the output side of the calculation means 12, the new current warehouse weight is compared with the replenishment order weight stored in the storage means 2, and if the former is smaller, a replenishment request signal is output. The comparing means 14 is connected. The output side of the comparison means 14 is connected to safety out-of-stock display means 15 for receiving the replenishment request signal and displaying safety out of stock. Further, the output side of the comparison means 14 is connected to the writing means 3. Then, the safety stock out is stored in the storage means 2.

Next, the operation of the above configuration will be described with reference to FIGS.
This will be described based on the flowchart shown in FIG. First, in step S1, the name of the compound to be prepared is specified by the input means 1, and in step S1A, the current storage weight of all the raw materials of the corresponding compound stored in the storage means 2 is stored. It is checked whether or not the flag 1 indicating that is smaller than the replenishment order weight is set. As a result, if the result is NO, the current warehouse weight is sufficient, so the process proceeds to S2, where the first raw material of the formulation is called.

If YES in step S1A (when the replenishment request signal is output), an alarm is displayed on the screen of the display unit 5 by the safety out-of-stock display means 15 (S21). Notifies that the current warehouse weight has run out of safety stock. Thus, the worker replenishes the raw material corresponding to the storage container 21, inputs the current storage weight of the replenished raw material from the input means 1, and then turns on the storage key indicating completion of the replenishment.

Subsequently, in S22, it is determined whether or not the raw material has been replenished, that is, whether or not the above-mentioned storage key has been turned on.
If the answer is YES, the alarm is released in S23. Subsequently, in S24, the flag is set to 0, and the process proceeds to S2. As described above, before starting the material blending operation shown in S2 and below, it is determined whether or not the raw material is in stock (S1A). If the current stock weight of the raw material is insufficient, replenishment is completed. Since the compounding operation is started after that, there is no problem that the operation is interrupted due to the shortage of the raw material being found during the compounding operation, and the operation is facilitated.

In S2, the first raw material of the compound is called, and the raw material display means 51 of the display 5 displays the raw material name and the shelf number (or container number) in which the raw material is stored (S2).
3) is done. The operator takes out the raw material storage container from the displayed shelf.

As shown in FIG. 4, a shelf 22 on which a raw material storage container 21 is placed has a shelf number TN that can be read visually,
A bar code TC encoding a shelf number is attached, and the operator brings the reading means 6 such as a hand scanner close to the displayed shelf 22 and displays the raw material identification bar code attached thereto. Read (S4 in FIG. 2). The raw material name read data is collated with the raw material name displayed on the raw material display means 51 of the display 5 by the raw material coincidence detecting means 8 (S5), and the result of this collation is judged by the detecting means 8 ( S6) If the determination result by the detection means 8 is NO,
That is, when the raw materials do not match, the mismatch is displayed on the screen of the display unit 5 by flashing to notify the worker, and the process returns to S2 to repeat the work.

In the case of YES where the raw materials match in S6,
In S7, the blending amount display means 52 of the display 5 displays the raw material instruction amount (blending amount) of the blend. Thereby, the worker can know the blending amount for the first time and can proceed to the next weighing operation. Therefore, the operation does not shift to the weighing operation with the raw materials mismatching, so that an operation error is prevented.

Then, in S8, the raw materials are taken out of the storage container 21 and weighed by the weighing machine 7, and the weighed value is input to the blending amount coincidence detecting means 9 (S9).
The detecting means 9 displays the measured value and the blending amount display means 52.
It is determined whether or not the difference from the indicated raw material amount is within a certain allowable range (S10). If the judgment result is NO,
This is indicated by a flash on the display 5 and, upon seeing this, the operator performs re-weighing by the weighing machine 7, and the detection means 9 waits until the determination result becomes YES, and the result is YES. If it is, the process proceeds to S11.

In S11, it is determined whether or not the weighing completion key of the input means 1 is turned on. If NO, the process waits until the completion key is turned on. If YES, the inventory management mode shown in FIG. Move on to flow. Instead of the input operation using the completion key, a setting may be made so that a completion signal is automatically output when the raw material is measured from the weighing machine 7.

In step S12 of FIG. 3, the weighing value of the weighing machine 7 is subtracted from the current warehouse weight to calculate a new current warehouse weight. The updating means 13 updates the current storage weight of the storage means 2 with the new current storage weight (S13). Thereby, the current storage weight after the raw material is used is stored.

The comparing means 14 determines whether the new current warehouse weight is greater than the replenishment order weight stored in the storage means 2 (S14). If NO, the safety stock out display means 15 determines Out of safety stock is displayed on the screen of the display 5 (S15). Further, the flag 1 is set based on the safety stock out (S16). That is, the replenishment request signal (flag 1) is stored in the storage unit 2 by the writing unit 3. Looking at the above safety out of stock display,
The operator replenishes the storage container 21 with the raw material, inputs the current storage weight of the replenished raw material from the input means 1, and then turns on a storage key indicating completion of the replenishment.

Even if the warehousing key is turned on, the flag remains at 1 indicating insufficient stock, so the process proceeds from S1A to S21 in FIG.
Is determined to be YES (replenished), and the alarm is released in S23.

On the other hand, the safety stock out display (S
If the worker who has watched 15) forgets to replenish the raw material, the flag is also 1, so that the alarm at S21 in FIG. 2 informs the worker of the safety shortage of the current warehouse weight, and the worker replenishes the raw material. Since the above-mentioned alarm is not released until then, the stock management of the raw material of the above-mentioned compound is surely performed.

Since the replenishment request signal (flag 1) is stored in the storage means 2, the operation is terminated without immediately replenishing the raw materials after the safety stock out display is made in S15 of FIG. However, when the next operation is performed, the out-of-safety stock stored in the storage means 2 is displayed on the out-of-safety stock display means 15 (S21).
Workers do not overlook safety.

If the result of the determination in S14 is YES and the safety is not out of stock, it is determined in S17 whether batch control is designated by the input means 1 or not.
In the case of NO, it is determined in S18 whether or not the raw material is the last raw material to be used for the compounding. In the case of YES, the operation is terminated. On the other hand, in the case of NO in S18, the process of S19 is ended. Then, the reading means 4 is controlled by the step advancing means 10, and the next raw material is instructed. The process proceeds to S2 in FIG. 2, and the name of the next raw material and its storage location (shelf number) are displayed.

The result of the determination in S17 of FIG. 3 is YES.
In the case of (the number of batches has not been completed), it is determined in S20 whether or not the operation by the batch control means 11, that is, whether or not the number of batches input by the input means 1 has been completed. Proceeding to S2, the operation for the same raw material is repeated. If YES in S20 (the batch number ends), the process proceeds to S19, where the next raw material is instructed.

[0029]

As described above, according to the raw material inventory management apparatus of the present invention, the present storage weight of the compound stored in the storage means and the weighing value measured by the weighing machine for the compounding are currently stored. The new storage weight calculated by the storage calculation means is compared with the new current storage weight calculated by the current storage calculation means and the replenishment order weight stored in the storage means, and when the former is smaller, the replenishment request is Output a signal to the safety out-of-stock display means,
Since the worker is notified of the safety shortage of the storage weight at present, the worker can restock the raw material based on the display result of the display means, so that the raw material inventory management of the compound can be accurately performed.

Further, since the replenishment request signal is input to the storage means via the writing means, when the work is completed once and the work is performed again, the current storage weight stored in the storage means is stored. By displaying the safety break on the display means, it is possible to prevent the worker from forgetting to break the safety.
