Abstract

PROBLEM TO BE SOLVED: To always enable accurate metering, by making a metering stand ascend, making a metering means be in the unloaded state, and performing zero point adjustment. SOLUTION: A metering stand 11 is not fixed in the state that the stand is mounted on an elevating rod 13 driven by elevating mechanism 3. When the elevating rod 13 ascends as far as the set upper limit, the metering stand 11 is pushed up by the rod 13, and a sensor 14 is turned into the unloaded state. When the rod 13 descends as far as the set lower limit, the metering stand 11 leaves from the rod 13 and is turned into the metering state retained by the sensor 14. A fine signal corresponding to the load of metering object W which signal is outputted from the sensor 14 is amplified by an amplifying circuit 21. A digital signal of an A/D converter 22 which signal corresponds to the load is inputted in a CPU 23, which converts the inputted signal to a load signal by specified operation and displays it on a display unit 24. In this case, the unloaded state that the metering stand 11 is excluded is set as a zero point, and the sum of the weight of the metering stand 11 and the weight of the metering object W is displayed as the measured value, thereby always enabling accurate metering.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weighing machine having an automatic zero-point adjusting function suitable for inventory control of general products.

[0002]

2. Description of the Related Art Conventionally, an electric signal from a load cell type or a capacitance type load sensor is converted into a digital signal, which is converted into a weight value by a processing means including a CPU and is digitally displayed. An electronic weigher is used. In such an electronic weigher, the characteristics of load sensors and circuit elements are affected by temperature changes in the operating environment and temperature changes due to self-heating of components inside the device, and fluctuations in the zero point, etc. This has deteriorated the accuracy of weighing instrument measurement.

[0003] The following causes are mainly considered as causes of deterioration of measurement accuracy due to such temperature change. One is that the zero balance of the load cell (strain gauge) constituting the sensor for detecting the weight changes according to the temperature change. In addition, since the output voltage of the sensor is small, the amplifier circuit is configured by an operational amplifier or the like. One of the causes is temperature characteristics of peripheral components such as a semiconductor and a resistor that constitute the operational amplifier.

[0004] In addition, temperature characteristics such as a semiconductor and a resistor used for the A / D converter are also a cause. Further, the power supply voltage fluctuates due to the temperature characteristics of the circuit elements of the power supply circuit, and the reference voltage supplied to the A / D converter fluctuates due to a temperature change.

[0005] The temperature caused by the sensor is corrected by a temperature correction gauge or a temperature correction resistor. In addition, using two sensors having the same temperature characteristic, one is used for measuring a weighing device, and the other is used without applying a load, and a temperature difference is obtained by calculating a difference between outputs of the two sensors. There are ways. For the amplifier circuit, a method of performing temperature correction using a temperature correction resistor on the input side or output side of the amplifier circuit or a feedback circuit is used.

In addition, for the A / D converter, A / D converter
There is a method in which an error signal due to a temperature change when the input signal to the D converter is set to zero is subjected to arithmetic processing to perform zero correction. For voltage fluctuations, a temperature control resistor is used in a voltage control circuit. Alternatively, there is a method using a reference voltage generating element having excellent temperature characteristics.

[0007]

Various methods for dealing with such individual causes complicate the circuit of the weighing device and increase the manufacturing cost. For a weighing device in which the load is applied for a long time, there is a problem that it is not sufficient to only electrically reduce the input to the A / D converter to zero or use a temperature correction resistor. In addition, using two sensors or using an element having excellent temperature characteristics has a problem in that the manufacturing cost increases.

Therefore, the present invention provides an effective and low-cost zero-point correction technique not only for a general weighing device but also for a weighing device in a usage form in which a load is applied for a long time. Furthermore, the purpose is to construct an accurate inventory management system by applying the technology. Furthermore, as a new application field of such a weighing device, for example, a field of inventory management of medicines and the like in hospitals and pharmacies is assumed, and a purpose is to propose a system capable of accurately controlling inventory in this field. is there.

Incidentally, the conventional inventory management system for medicines and the like in hospitals and pharmacies is a medicine in the form of a sheet-like package in which tablets are wrapped, a large number of sachets in which powder is stored, and a sheet-like form. Since there are various forms such as a poultice in which a predetermined number of poultices are sealed in a sealed bag, these are divided and stored in a storage rack having a number of drawers or shelves for management.

However, since there are many types of chemicals to be handled, the number of drawers in the storage rack increases, and it is extremely troublesome to manage how much the medicines stored in these drawers are in stock. In the case of a drug in the form of a cartridge, if it is held in the middle of storage or withdrawal, it may be erroneously recognized that the stock is full, so that there is a problem that good inventory management cannot be performed.

In order to solve these problems, a microswitch and an optical sensor are provided in each drawer of the storage rack,
It is conceivable to perform inventory management by detecting the quantity with these microswitches and optical sensors, but because the types and forms of pharmaceuticals are diverse, it is not possible to accurately detect the inventory amount for all types. Therefore, even if it is detected, it can only be detected by discriminating whether there is a stock (ON) or not (OFF), and thus cannot detect the amount.

Even in this case, when the stock becomes low, the corresponding item must be ordered from a dealer or a wholesaler, and the ordering operation involves placing an order slip or placing an order by telephone or the like. There has been a problem that the work is required, and the work is cumbersome. On the other hand, there is a combination weighing shelf disclosed in Japanese Utility Model Laid-Open Publication No. Hei 7-42487 as a known technique for detecting an amount by a weighing machine.
g) Automatically select and display at a high speed the required number of objects to be weighed that are combined within the range of the combination weight value that is set in advance when selling items packed in one bag. The purpose of the present invention is to provide a weighing shelf that can be used, and is not intended to provide a weighing scale for each storage unit and measure the stock amount individually.

[0013] By introducing a weighing device into such a conventional inventory management system for medicines and the like in hospitals and pharmacies, a large number of commodities stored in each storage section are individually measured to reduce the amount of inventory. Providing a subdivision storage device with a weighing device that can be grasped greatly contributes to improvement of an inventory management system for pharmaceuticals and the like.

[0020]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a weighing machine according to claims 1 and 2 of the present invention will be described in detail with reference to the drawings showing an embodiment thereof.

FIG. 1 is a block diagram showing the configuration of the weighing device of the present invention. In FIG. 1, 1 is a weighing unit, and 2 is a control unit. A weighing object W to be weighed is placed on a weighing table 11 provided in the weighing section 1. The weighing table 11 is placed on a lifting rod 13 driven by the lifting mechanism 3 and is not fixed. When the lifting rod 13 descends to the set lower limit, the weighing table 11 separates from the lifting rod 13 and enters a measurement state supported by the sensor 14 as shown in FIG. When the lifting rod 13 has risen to the set upper limit, as shown in FIG.
And the sensor 14 is in a no-load state.

The amplification circuit 21 provided in the control unit 2 amplifies a weak signal corresponding to the load of the weighing object output from the sensor 14 and outputs the signal to the A / D converter 22. A digital signal corresponding to the load output from the A / D converter 22 is input to the CPU 23, converted into a load signal based on a predetermined arithmetic expression, and displayed on the display 24. Power to the scale is provided from a battery or 100 VAC via a stabilized power circuit.

As shown in FIG. 3, the detailed structure of the elevating mechanism 3 is provided with a conversion mechanism 32 for converting the rotational movement of the motor 31 into the elevating movement of the elevating rod 13.
Driven by a drive circuit 25 by 23. Lifting rod
The position of the measurement surface 141 of the sensor 14 is set at a position higher than the lower limit position L and lower than the upper limit position H.

Program P1 as zero point adjusting means
As shown in FIG. 4, after confirming that the sensor 14 is in a no-load state in step S11, the digital value D0 input from the A / D converter 22 to the CPU 23 in step S12 is changed to a new zero point. Set as
That is, the zero point correction value to be subtracted from the digital value D input from the A / D converter 22 to the CPU 23 at the time of measurement is updated to the digital value D0.

Therefore, in the subsequent measurement, the updated zero point correction value D0 is subtracted from the digital value D input from the A / D converter 22 to the CPU 23, and the measurement is performed. At this time, the state excluding the weighing platform 11 is assumed to be a zero point in a no-load state, and the condition is such that the total weight of the weight of the weighing platform 11 and the weight of the weighing object W is displayed as a measured value.

The program P2 as control means is shown in FIG.
As shown in (2), the zero point adjustment is performed after the power switch is turned on, and in step S21, integration of the elapsed time by the timer built in the CPU 23 is started. In step S22, a weighing operation is performed. In step S23, it is checked whether or not the accumulated time in the timer has exceeded a predetermined set time. If not, the process returns to step S22. In the no-load state, the fluctuation of the zero point with respect to the temperature change is corrected by the same zero tracking method as that of the related art.

If the predetermined time is exceeded in step S23, the metering operation is interrupted in step S24, and a rising start signal is output to the drive circuit 25 in step S25. The drive circuit 25 drives the lifting mechanism 3 to lift the weighing table 11 by the lifting rod 13. When it is confirmed in step S26 that the position has risen to the upper limit position H and an upper limit confirmation signal is input, the above-described zero point adjustment program P1 is started in step S27, and the digital value input from the A / D converter 22 to the CPU 23 is output. D1 is set as a new zero point. That is, the A / D converter 22
The zero-point correction value to be subtracted from the digital value D input from the CPU 23 to the CPU 23 is updated to the digital value D1.

After reading the digital value at the time of no load in this way, a descent start signal is output to the drive circuit 25 in step S28. In step S29, the weighing table 11
Is lowered to the lower limit position L and the weighing object W is placed on the weighing table 11 to resume weighing, and the process returns to step S21. As described above, the program P1 is automatically started every predetermined elapsed time, and the zero point is adjusted periodically.

The weighing table 11, the sensor 14, and the amplifying circuit 21
, The A / D converter 22, the CPU 23, and the display 24 correspond to the measuring means, the program P1 corresponds to the zero point adjusting means, and the elevating mechanism 12, the elevating rod 13, and the drive circuit 25 correspond to the elevating means and the descending means. Correspondingly, the program P2 corresponds to the control means.

The upper limit confirmation signal and the lower limit confirmation signal may be obtained from limit switches disposed at the upper limit position and the lower limit position, but may be obtained from a software timer in which the time required to reach the upper limit position or the lower limit position is set in advance. Alternatively, the amount of rotation of the motor may be obtained by integrating pulses and drive pulses from the rotary encoder. Further, as the sensor 14, a load cell having a built-in strain gauge, a capacitance type load sensor, various piezoelectric elements, or the like can be used.

With the weighing device of the present invention having the above-described configuration, the zero point adjustment by the zero tracking method in the no-load state and the zero point adjustment by forcibly creating the no-load state by the elevating mechanism are performed. Therefore, it is always possible to accurately measure the weight.

As shown in FIGS. 1, 2 and 3, the lifting mechanism 3 may be an integral type built in the main body, as shown in FIGS.
As shown in the above, a device added to the conventional weighing device 4 may be used. That is, the arm 51 that can be supported on both sides of the weighing table 41 of the conventional weighing device 4 may be configured to be moved up and down by the screw lifting mechanism type additional device 5A or the cam lifting mechanism type additional device 5B. .

The screw lifting mechanism type additional device 5A includes:
The rotation of the motor 52 is reduced by the gear box 53 and transmitted to the screw shaft 54, so that the arm 51 rises when the screw shaft 54 is rotated forward, and the arm 51 is lowered when the screw shaft 54 is rotated reversely. You may. The cam lifting mechanism-type additional device 5B may be configured so that the rotation of the motor is reduced by the gear box and the eccentric cam 55 is rotated so that the arm 57 inserted through the guide shaft 56 is raised and lowered.

According to these additional devices 5A and 5B, even when the conventional weighing device 4 is used as a weighing device in a use form in which a load is applied for a long time, the zero point is effectively corrected. Therefore, the effect of expanding the use of the conventional weighing device can be obtained.

Next, an embodiment of a subdivision storage device with a weighing device according to claims 3, 4, 5, 6, and 7 will be described with reference to the drawings. FIG. 7 shows a storage rack showing an example of the embodiment of the present invention, which is placed in the order of 61A, 61B, 61C from the left, and these storage rack groups are divided into a plurality of stages, and the storage racks 61B, 61C are further provided with Each of the storage portions 62 has a plurality of partitions 61a, 61a,.
Is formed. As shown in a storage rack 61A, a storage box 63 which is open at one side and surrounded on three sides is stored in the storage section 62. The storage box 63 in this example has It shows a state in which a plurality of bottles of medicine are installed.

FIG. 8 shows the loading state of the medicine. FIG. 8 (A) shows a small storage box 63A on which two capsule tablets 64 are placed, and a weighing device 65A placed below it.
(B) is a large storage box 63B on which two bottles 66 are placed.
And a weighing device 65B placed below the weighing device 65B. As the weighing device 65B, it is preferable to use the weighing device shown in FIGS. 1, 2, 3, and 6 or an additional device of the weighing device according to the first embodiment of the present invention. A specific example in that case is shown in FIGS.

In FIG. 14, a weighing table 91 of a weighing device 90 is shown.
Is mounted with a storage rack 92 in which a medicine is stored. The weighing table 91 is provided with four lifting rods 93 driven up and down by the lifting mechanism configured as described above. During the weighing, the lifting rod 93 is buried from the surface of the weighing allowance 91. However, when the zero point is adjusted, the lifting rod 93 is protruded by the lifting mechanism and lifted to the storage rack 92 to lift the weighing table 9.
Move away from 1.

FIG. 15 shows a configuration in which an additional device 95 having a lifting mechanism is added to the weighing device 94. In this case, the storage rack 97 storing the medicine is lifted by the lifting rod 96 provided in the additional device 95 to perform the zero point adjustment.

FIG. 9 shows the storage state when the medicine placed in the storage box 63 is a small item such as the ampule 68 shown in FIG. 9A, and it is difficult to store each ampule 68 in an individual state. Therefore, a plurality of ampules 68
And the storage guide 67 is stored in the storage box 6.
3A. FIG. 10 and FIG.
1 shows a schematic configuration diagram of inventory management of medicines stored in the storage rack, and the medicines A, B, C, D,... Stored in the respective storage portions 62 of the storage rack 61 in FIG. Each of the weighing devices 65 provided is weighed and its numerical signal is collected as input means 69 in a storage means 70 shown in FIG.

That is, the current weight of the medicines A, B, C, D,... Stored in the respective storage sections 2 of the storage rack 61 in FIG. 10 is, for example, 10 g, 12 g, 15 g, 1 respectively.
8g,..., This numerical signal
These are stored in 0 and are calculated by the arithmetic processing means 71, and are collectively managed by the inventory management means 72 which controls them. Therefore, the stock management means 72 grasps the current stock quantity of the medicine in real time.

In this case, as described above, the inventory management means 72 displays an input means 69 based on a numerical signal or the like for inputting the measurement data from each storage section 62 to the storage means 70, and displays the data stored by the input means 69. Storage means 70 and an arithmetic processing means 71 for calculating data from the storage means 70. The arithmetic processing means 71 receives stock detection information from the weighing devices 65 of the individual storage portions 62 of the storage rack 61. A display or the like (not shown) of a personal computer capable of displaying data of the lacking management target product name as a product requiring replenishment is provided.

Thus, all the quantities of the names of the management objects calculated based on the inventory detection information from the weighing devices 65 of the individual storage sections 62 of the storage rack 61 are all stored in the inventory management means 72.
Therefore, the inventory management means 72 can easily detect, by data display, the names of the objects to be managed of the medicines which have been reduced by taking out from the respective storage units 62 and need to be replenished.

In this case, when the name of the management object requiring replenishment is detected, the inventory management means 72 changes the name of the management object requiring replenishment by the ordering means 74 through the communication line 73 at a predetermined timing. Or report data 75 can be sent.

Next, the first-in first-out management will be described.
In general, when unloading or consuming articles stored in the storage unit, it is appropriate to release and consume items in the order of arrival date and manufacturing date, but such lot management, that is, first-in first-out management, is difficult. There are many cases. In such management, in the case of the present invention, inventory management can be performed in the same manner as described above.

That is, as shown in FIG. 12A, a tablet 78 is divided into lots using a plurality of storage boxes 77 and placed in the front-rear direction with respect to a single measuring unit 76. Tablets 7 in first storage box 77 from before refilling
8 and sequentially use the tablets 78 in the storage box 77.
At the time when the second storage box 77 storing the next lot is stored at the forefront on the weighing unit 76, as shown in FIG. The first storage box 77, which has been emptied, is placed at the end as a storage box 77 containing a new tablet 78, so that the first-in first-out operation for each lot can be performed. It becomes possible.

It is also possible to arrange a plurality of weighing units under one storage box and add the load signal obtained from each weighing unit to know the load of the storage box. In this way, even when measuring storage boxes of various weights, it is possible to cope with the combination of a plurality of weighing units.

FIG. 13 also shows the case of the bottle 81.
As shown in FIGS. 12A and 12B, the procedure can be performed in exactly the same manner as for the tablet 78, and therefore, the parts are denoted by the reference numerals of the measuring unit 79 and the storage box 80 different from those in FIG. As described above, when the present invention is applied to medicine inventory management in a hospital, the following various effects can be obtained.

1) By grasping how many medicines are in stock as numerical management, it is possible to grasp the individual stock status of the medicines to be managed in real time, and it is possible to carry out an inventory work on a daily and automatic basis. Time and expense are greatly reduced. Also, in large hospitals, the efficiency of reporting and use of medicines and pharmaceutical materials for the entire hospital can be improved by simultaneously recognizing the usage and stock status in each ward. Further, since an ordering means for ordering medicines to be replenished is also provided, it is possible to prevent an accident such as an order delay or an order error.

2) The management of the individual drugs to be managed by the management computer means that the increase / decrease of the stock can be managed by the individual increase / decrease, which is convenient for the administrator. 3) Recognition of not only the current amount of goods but also the change in total consumption in each ward and hospital as a whole can be used to analyze trends in the movement of goods and is an important source for setting appropriate inventory.

In inventory management of pharmaceuticals in large hospitals, etc., it is apt to secure excess inventory in order to prevent out-of-stock situations based on inaccurate management information. According to the apparatus, since accurate management information can be obtained, an appropriate inventory can be maintained with a sense of security, so that there is an effect that waste is eliminated. 4) Since the setting of the replenishment point for the shortage can be performed only by inputting it to the computer, the setting work is greatly reduced.

Although the present invention has been described mainly in the case of pharmaceutical products in the embodiment, the present invention is not limited to pharmaceutical products, and is applicable to, for example, inventory management of small parts including bolts and nuts required for machine assembly. It goes without saying that the same effect is achieved. In addition, by appropriately changing the specifications of the weighing device and the structure of the rack, not only small items,
The same effect is exerted in the management of heavy objects. In particular, in a case where a plurality of stockyards are arranged in a series of related buildings, a remarkable effect that accurate inventory management can be performed in real time is obtained. For example, if the present invention is applied to a display shelf of a convenience store or the like, the inventory work can be improved as described above.

Further, the shapes of the objects to be managed are various, and it is necessary to employ a receiving tray, a container, a support, etc. corresponding to the shape of the objects to be managed as the storage guide for storing the objects.
These pans, containers, supports, etc. naturally have their own weights.However, in order to properly manage the inventory of stored products, the weight other than those to be managed is deducted as the tare weight, and the net weight of only the target is calculated. Must be weighed. In this regard, in the present invention, the weighing data in a state where only containers other than the management target are set in advance is recognized as the tare weight, and after storing the target, the tare weight is subtracted from the total weight to determine the target weight. Is calculated. The degree of freedom of the shape of the storage guide and the like is improved by the deduction function of the tare weight, and the range of the object to be managed is greatly expanded.
In addition, the total weight in the case where the quantity is 0 can be calculated based on the change in the quantity of the target object and the change in the weight associated therewith to obtain the tare weight.

Further, by using the weighing device according to the first aspect or the additional device of the weighing device according to the second aspect, it is possible to always perform accurate weighing by forcibly adjusting the zero point. More accurate inventory management becomes possible. In addition, the inventory management is mainly used as a fuel gauge, but the same effect can be obtained not only for the remaining capacity but also for the measurement management of the additional load.

[0054]

According to the weighing device of the first aspect of the present invention, the lifting device for lifting the weighing object on the weighing table to bring the measuring device into a no-load state is provided, thereby forcibly reducing the no-load state. Since it is made and zero-adjusted, accurate weighing is always possible compared to zero-adjustment using only the conventional zero tracking method.

According to the apparatus for adding a weighing device according to the second aspect, by adding the weighing device to a conventional weighing device, it can be used as a weighing device having the same effect as described above.

According to the subdividing storage device with a weighing device according to the third, fourth and fifth aspects, the number of stocked commodities is grasped as numerical management, so that the stock status of the managed commodities can be grasped in real time, Since the stocktaking operation can be performed automatically and automatically, the time and cost can be greatly reduced. Also, in cases where the object is used in multiple departments or inventory is managed in multiple stock yards, the product status can be recognized simultaneously and collectively by the status of use in each department and the inventory status in each stock yard. Not only enables effective inventory management, but also becomes a valuable source of information on setting appropriate inventory.

Further, the management of the individual management objects by the management computer can manage the increase / decrease transition of the stock of the goods by the individual increase / decrease, which is convenient for the manager's work. Also, not only the current inventory of products,
Since the ordering of commodities requiring replenishment can be automated, accurate and proper replenishment is possible.

Further, since the setting of the replenishment point for the shortage can be performed only by inputting it to the computer, the setting operation is greatly reduced.

In addition, in addition to the above effects, the subdivision storage device with a weighing device according to claims 6 and 7 can always perform accurate weighing by forcibly adjusting the zero point, so that more accurate inventory management can be performed. Is obtained.
