2. Description of the Related Art Conventionally, the inventory management of medicines has been carried out by a sheet containing tablets containing medicines, a sheet formed by connecting a number of sachets containing powders, or a predetermined number of sealed bags such as poultices. Since it takes various forms such as those enclosed in, it is necessary to divide and store these in a chemical storage with a large number of drawers, but since there are many types of chemicals to handle, The number of drawers is large, and it is troublesome to manage the inventory of medicines stored in these drawers. There was an unsolved problem that good inventory management could not be performed in some cases because it was mistakenly recognized as full.

[0003]

In order to solve this unsolved problem, a micro switch or an optical sensor is provided in each drawer of the storage, and the quantity is detected by the micro switch or the optical sensor to inventory. Although it may be possible to manage, it is not possible to accurately detect the inventory amount across all varieties due to the wide variety of drug forms as described above, and it is not possible to secure reliability, and it is also possible to use micro switches and There is an unsolved problem that the manufacturing cost increases due to the large number of installed optical sensors.

Further, when a partition plate is provided in the drawer to form a plurality of storage areas, a connecting board is provided to connect the sensors in the storage areas to each other.
There was also an unsolved problem that this also contributes to the cost increase.

Therefore, the present invention has been made by paying attention to the unsolved problems of the above-mentioned conventional examples, and it is possible to accurately confirm the inventory of controlled products such as pharmaceuticals with a simple and inexpensive structure. It is intended to provide an inventory management device for the above.

[0006]

In order to achieve the above object, an inventory management device for medicines and the like according to claim 1 stores a controlled object such as medicines in a storage rack having a large number of storages.

Control unit in which the inventory detection sensor having at least an upper plate supported by a flexible sheet and an elastic member having a predetermined spring constant for the flexible sheet and the inventory detection sensor of each storage unit are connected via a communication cord And a unit.

According to a first aspect of the present invention, the inventory detection sensor arranged at the bottom of the plurality of storages is supported by a flexible sheet having a contact and an elastic member having a predetermined spring constant for the flexible sheet. Since it is configured with the upper plate, when a controlled object such as a drug is placed on the upper plate, when the weight is equal to or more than the preset load according to the spring constant of the elastic member set in advance, The elastic member contracts, the folded portion of the flexible sheet is pressed by the upper plate, and the contact formed on the opposite surface comes into contact, so that the inventory detection information indicating the stock state is output.

After that, when the managed object is consumed so that the remaining weight of the managed object in the storage portion becomes equal to or less than a predetermined value, the elastic member separates the upper plate from the flexible sheet, thereby the folding part The contact formed on the opposite surface is opened and inventory detection information indicating that there is no inventory is output.

Since the inventory detection information output from the sensor is directly connected to the control unit via the communication code, a connecting board or the like is not required, which contributes to a reduction in manufacturing cost.

According to a second aspect of the present invention, there is provided the inventory control device for medicines and the like, wherein the control unit has row lines and column lines arranged in a matrix.
An inventory detection sensor is connected to the intersection of the row line and the column line via a sneak diode and a communication code, and one of the row line and the column line is sequentially selected, and the other is scanned, thereby sequentially. It is characterized in that the inventory management information is serially output.

Further, in the invention of claim 2, the control unit has column lines and row lines arranged in a matrix form, and the sensor of each storage section is connected to the intersection position of these through a communication cord. Therefore, for example, by scanning the row lines while sequentially selecting the column lines, it is possible to sequentially obtain the inventory detection information of the sensor of each storage unit as a serial output,
Data can be easily transmitted to a management unit that manages inventory based on the inventory detection information.

At least. A similar management list is created for the small amount storage unit 3.

Before starting to use the storage racks 1A and 1B, a management list is displayed on the color display 30b.
, Enter the medicine name to be stored in the medicine name display field 35c from the keyboard 30a in this state, enter the storage unit in the unit display field 35e, and leave the storage area in which the drug is not stored blank When input is complete, the created management list is stored in the hard disk drive 3
Store in 0c.

Next, the inventory management process executed by the personal computer 30 will be described with reference to FIG. The stock management process is started when the stock management process is selected from the menu displayed on the color display 30b or at predetermined time intervals.

That is, in step S1, first, the storage rack 1
Set the variable i for selecting A and 1B to "1",
Next, in step S2, it is determined whether or not the variable i is 1, and when i = 1, the process proceeds to step S3 to select an identification code preset for the storage rack 1A. To step S5, and when i = 2, the process proceeds to step S4 to select an identification code preset for the storage rack 1B, and then proceeds to step S5.

In step S5, the matrix column line B
A variable j to select the ₁ .about.B ₁₀ is set to "1", then the process proceeds to step S6, is composed of a column line designated code specified by the selected identification code and the variable j in step S3 or S4 Request to send inventory detection data to the system bus.

Next, in step S7, inventory detection data representing the output state of each row line C ₁ -C ₁₀ corresponding to the column line B _j is received from the system bus input / output interface 21 of the corresponding storage rack 1A. If the inventory detection data is not received, the process waits until the inventory detection data is received. When the inventory detection data is received, step S
The inventory detection data received after shifting to 8 is updated and stored in a predetermined storage area of the hard disk device 30c.

Next, in step S9, it is determined whether the variable j is "10". This judgment is made on the column line B.
₁ for all .about.B ₁₀ are those stored inventory detection data to determine whether or not it is completed, when it is j <10 is the step S10 it is judged that the storage of the inventory detection data is not completed Then, the variable j is incremented by "1" and then the process returns to step S6, where j = 10.
If it is, it is determined that the storage of the inventory detection data is completed, and the process proceeds to step S11.

In step S11, it is determined whether the variable i for selecting the storage rack is "2". If i = 1, the process proceeds to step S12 and the variable i is set to "2". Then, the process returns to step S2, i = 2
If it is, it is determined that the storage of the inventory detection data has been completed for all the storage racks 1A and 1B, and the process proceeds to step S13.

In step S13, it is determined whether or not there is an inventory-deficient article based on the inventory detection data stored in the hard disk drive 30c. In this determination, the inventory detection data is a logical value "0", that is, all of the switch units 12d to 12g of the sensors 10A to 10C and 10D in the drawers 2a and 3a are turned off, and the common print wiring 12k and the individual print wiring are detected. This is performed by determining whether or not the area between 12p and 12r is in the cutoff state.

At this time, when all the inventory detection data have the logical value "1", it is judged that the stock is in the proper stock state, and the process proceeds to step S14. ", And then step S1
If there is inventory detection data of logical value "0" in step 6, write "no inventory" in the inventory presence / absence display column 35d of the corresponding storage area of the management list, and then execute step S1.
Go to 6.

In step S16, the storage area display area 36a of each drawer 2a and 3a as shown in FIG. 11 and the presence / absence of inventory are different based on the data of the management list (for example, blue with inventory, red without inventory). The display data for performing the inventory status display 36 composed of the stock presence / absence display area 36b displayed in FIG.
After outputting to 0b, the inventory management process is terminated.

The personal computer 30 also executes the ordering process shown in FIG. 12 at a predetermined time or at a desired time.

This ordering process is started at a predetermined time set in advance or at any desired time when the execution start is input from the keyboard 30a. First, in step S21, the inventory presence / absence display column 35d of the management list is searched to obtain the drug name. Is specified and whether or not there is a storage area that is in the out-of-stock state. If there is no storage area that is in the out-of-stock state, the process proceeds to step S22 and the stock state is appropriate. The guidance display information to that effect is output to the color display 30b, this is displayed, and then the process is terminated. If there is a storage area in which there is no stock, the process moves to step S23.

In step S23, the medicine name of the storage area in the out-of-stock state is extracted, and based on this medicine name and the order quantity preset for each medicine name, as shown in FIG. An order list is created and stored in the hard disk device 30c. Then, the process proceeds to step S24, and display data for displaying the order list is sent to the color display 30b and displayed.

Next, in step S25, guidance display information indicating whether or not to accept the order is sent to and displayed on the color display 30b.

Next, in step S26, it is determined whether or not there is a predetermined key input for accepting the order from the keyboard 30a, and when there is a predetermined key input, the process proceeds to step S27 and is stored in the storage device in advance. The stored order number is referred to, the order list is transmitted to the host computer of the other party through the telephone line 33, and then the order process ends.

On the other hand, if the result of determination in step S26 is that there is no predetermined key input, the process proceeds to step S28,
It is determined whether or not there is a predetermined key input that does not place an order. If there is a predetermined key input, the ordering process is terminated as it is, and if there is no predetermined key input, step S
Return to 25.

Next, the operation of the above embodiment will be described.
First, when installing the inventory management device, the storage racks 1A and 1
The name of the medicine to be stored in the storage area of each drawer 2a and 3a of B is determined, and based on this, the color display 30b
A management list is displayed in, and the determined drug name is written in the drug name display column 35c corresponding to each storage area, and the storage unit of the drug is written in the unit display column 35e. Set the order processing start time.

On the other hand, for each storage area of the storage racks 1A and 1B, the minimum weight for detecting the stock shortage condition corresponding to the medicines stored therein is calculated, and the compression coil set to the spring constant corresponding to this is calculated. The spring 14 is selected, and the spring 10 is connected to each of the sensors 10A to 10C and 10 in the storage area.
Set to D.

Thereafter, a predetermined amount of the corresponding drug is stored in the storage areas of the drawers 2a and 3a of the storage racks 1A and 1B, respectively. In this way, by storing a predetermined amount of medicine in each storage area, each of the sensors 10A to 10C and 1
The 0D upper plate 13 is lowered against the urging force of the compression coil spring 14, the folded portions 12b and 12c of the printed circuit board sheet 12 are compressed, and the movable contact 12j formed on the inner surface side thereof is The pair of fixed contacts 12h and 12i formed on the lower side come into contact with each other, and the common printed wiring 12k and the individual printed wirings 12p to 12r are brought into conduction.

In this initial state, since a predetermined amount of medicine is stored in each storage area, a preset processing start time is reached or there is a key input to start the stock management start processing from the keyboard 30a when desired. 9 when the inventory management process of FIG. 9 is started, the system bus input / output interface 21 of each of the storage racks 1A and 1B excludes the non-stored region in which the storage of the medicine is not determined, and all the other storage regions. The sensors 10A to 10C and 10D are in the ON state.

Therefore, each of the sensors 10A to 10C and 1
When the row lines C _{1 to} C ₁₀ are scanned by the encoder 25 in the state where the column lines B _{1 to} B ₁₀ to which 0D is connected are designated, the logical value “1” is output from all the row lines C _{1 to} C _10. Since the output signals of "" are obtained and are input to the personal computer 30 via the system bus, the inventory presence / absence display column 3 corresponding to the storage area in which the medicine is set in the management list
"Yes" is automatically set in 5d.

When the inventory confirmation for all the storage areas of the storage racks 1A and 1B is completed and the management list is updated, inventory status display data is formed and sent to the color display 30b. , Figure 1
The inventory status display shown in FIG. 1 is displayed, and it is possible to easily visually recognize the presence or absence of the inventory product from the inventory status display. At this time, since all the stored medicines are in stock, the stock presence / absence display area 36b of the stock status display 36 is displayed in blue indicating that there is stock.

As described above, when all the medicines are in stock, when the ordering process of FIG. 12 is started to be executed at a predetermined time, the process is finished as it is from step S21, so that no order is placed. .

However, by consuming the medicines stored in the storage areas of the drawers 2a and 3a of the storage racks 1A and 1B, the sensor 10 of the corresponding storage areas is consumed.
When the load on the upper plate 13 of A to 10C or 10D decreases, and the load becomes smaller than the set load of the compression coil spring 14, the compression coil spring 14 raises the upper plate 13 upward, and accordingly the printed wiring The folded-back portions 12b and 12c of the substrate 12 are returned to the shape memory position,
The switch units 12d of the sensors 10A to 10C and 10D,
The contact states of the fixed contacts 12h, 12i of 12f, 12e, 12g and the movable contact 12j are released.

At this time, assuming that the medicines stored in the storage area are sequentially taken out from the front side, for example, the upper plate 13 on the front side returns to the upper side and the switch section 12 is returned.
Although d and 12e are turned off, in this state, since the drug remains on the rear side, the switch section 12 on the rear side is
If either one of f and 12g continues to be in the ON state, the common printed wiring 1 of the sensors 10A to 10C and 10D
Since the 2k and the individual printed wirings 12p to 12r maintain the conductive state, when these are scanned, the encoder 2
5, the signal of the logical value "1" indicating that there is stock is output,
This keeps the management list in stock.

After that, when the remaining weight of the medicine becomes less than the set weight by further consuming the medicine, the upper plate 13 of the corresponding sensor 10A to 10C or 10D is completely compressed by the compression coil spring 14 into the printed circuit board sheet 1.
It will be lifted from 2, and each switch unit 12d ~ 1
The movable contact 12j is separated from the fixed contacts 12h and 12i of 2g, and the common printed wiring 12k and the individual printed wirings 12p to 1
2r becomes non-conductive and shifts to the off state.

Therefore, when the inventory management process of FIG. 9 is executed, the sensors 10A to 10A in the storage area in which the inventory is low
When 0C or 10D is scanned, a signal of logical value "0" is output from the encoder 25 and is input to the personal computer 30. Therefore, "none" is displayed in the inventory presence / absence display column 35d of the corresponding storage area of the management list. 11 is displayed and the color display 30b displays the stock status display 36 of FIG. 11 in response. In the stock status display area 36b of the corresponding storage area, the stock status display area 36b changes from a blue color indicating that there is stock to a red color that indicates that there is no stock. It will be flipped to the display, which allows you to see exactly which medications need refilling.

Therefore, when the ordering process of FIG. 12 is executed after that, the medicine requiring replenishment is stored in the hard disk 3.
The management list stored in 0c is searched, and an order list is created with the medicines requiring replenishment and the order quantity set in advance for the medicines. With the order list displayed on the color display 30b, When a predetermined key is input to accept the order, the order list is automatically transmitted to the supplier on-line.

On the other hand, when the order list is displayed and there are few ordered products and there is no urgent ordered product, a predetermined key input indicating non-order suppressing the order is made to place the order. It is possible to suppress the order processing when the ordered products are collected at the next order processing.

As described above, according to the above embodiment, when there are many medicines stored in the storage areas of the drawers 2a and 3a of the storage racks 1A and 1B, the weight of the stock detection sensors 10A to 10C and 10D causes the stock detection sensors 10A to 10C and 10D to detect. When the inventory amount is reduced and the inventory amount is reduced and needs to be replenished, the inventory detection sensors 10A to 10C and 10D are turned off, and the presence or absence of the inventory can be accurately detected from the state of the sensor.

Moreover, the printed circuit board sheet 12 in which the inventory detection sensors 10A to 10D have contact points formed on the opposing surfaces of the folded portions 12b and 12c disposed on the lower plate 11, respectively,
Since the printed circuit board sheet 12 has a configuration including the upper plate 13 disposed via the compression coil spring 14 having a predetermined spring constant, the configuration of the switch unit for detecting the stock state is simplified. Therefore, the manufacturing cost can be significantly reduced.
