Abstract

PURPOSE: To obtain a counter scale in which the indication unit is matched between a weight indicating section and a unit weight indicating section when a weight unit system is switched between 1b and kg, for example. CONSTITUTION: When a 1b/kg key 14 is operated, a CPU 1 sets a kg flag to '1' if the 1b system is set currently and then multiplies the inner count W of weight by a kg conversion coefficient β to calculate the wright Wk in kg system. Similarly, the inner count UW of unit weight is multiplied by the kg conversion coefficient βto calculate the unit weight UWk in kg system. When kg system is set currently, the CPU 1 sets the kg flag to '0' and multiplies the inner count W of weight by a 1b conversion coefficient α to calculate the weight Wp in 1b system. Similarly, the inner count UW of unit weight is multiplied by the 1b conversion coefficient α to calculate the unit weight UWp in 1b system.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a counting scale for measuring the weight of an article, dividing the measurement result by the unit weight of the article to calculate the number of articles, and displaying or printing.

[0002]

2. Description of the Related Art In the United States, both a pound system unit and a kilogram system unit are still used together as a unit of weight. Here, 1 kg = 2.20463 pounds (1 pound = 0.453590 kg), and therefore, a scale capable of switching the weight display unit system (lbs / kilogram) has been developed by setting switches and key operations. (For example, see Japanese Patent Publication No. 62-30368).

The counting scale may be provided with two types of modes, a weight display mode in which only the weight is displayed and the number is not calculated, and a counting mode in which the number is calculated and displayed based on the weighing result. Many. In the conventional counter balance, normally, in the weight display mode, the pound / kilogram can be switched when displaying the weight. On the other hand, in the counting mode, the purpose is to count the number, and even if the weight unit system is changed, the calculated number does not change, so that the pound / kilogram can be switched. Was not configured.

[0004]

However, since recent counting scales are equipped with a printing means and issue a receipt / delivery slip or the like at the time of counting work, the weight value is often printed together with the counting result. It is preferable that the unit system (pound / kilogram) can be switched also in.
However, in the case of conventional counting scales,
In order to calculate the number by dividing this measured value by the unit weight stored in advance, as in the case of the conventional weight mode, simply switching the unit system of weight display will make the weight display unit and the unit There is a drawback that the display unit does not match the display unit of the weight.
Further, as described above, when the weight value and the unit weight value are printed together with the counting result by the printing means, the problem that the unit systems do not match occurs.

The present invention has been made under such a background, and when the weight unit system such as pound / kilogram is switched, the weight display unit and the unit weight display unit, or the weight value printing column. It is an object of the present invention to provide a counting balance in which the unit system between the unit and the unit weight value printing column always matches.

[0006]

According to the first aspect of the present invention,
In a counting scale for dividing the weight value weighed by the weighing means by the unit weight value to calculate the number, and displaying on the display means or printing by the printing means, a selecting means for selecting a unit system in the display means or the printing means. When the selection means is operated, together with the weight value, a conversion means for converting the unit weight value into a numerical value with the selected unit system as a unit,
It is characterized by further comprising display or print control means for displaying the weight value and unit weight value converted by the conversion means on the display means or for printing on the printing means.

According to a second aspect of the present invention, in the counting balance according to the first aspect, the selecting means selects the unit system from a pound system and a kilogram system.

According to a third aspect of the present invention, in the counting balance according to the first aspect, there is provided storage means for previously storing the unit weight value corresponding to each identification number of the article, and the unit weight value is the identification number. It is characterized in that it is read from the storage means based on a number.

According to a fourth aspect of the present invention, in the counting balance according to the third aspect, the unit weight value is an internal count value before being rounded to a numerical value with a preset unit system as a unit, and is stored in the storage means. It is characterized by being.

According to a fifth aspect of the present invention, in the counting balance according to the third aspect, the unit weight value is stored in the storage means as a numerical value in units of a preset unit system. There is.

[0011]

According to the above construction, when the selecting means is operated,
The conversion unit converts the unit weight value together with the weight value into a numerical value in which the unit system selected by the selection unit is a unit. Then, the display or print control means displays the weight value and the unit weight value converted by the conversion means on the display means or prints on the print means.

【Example】

§1. First Embodiment Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an electrical configuration of a counter balance according to a first embodiment of the present invention, and FIG. 2 is a perspective view showing the same external configuration. In these figures, 1 is a CPU (central processing unit), which controls each part of the device. 2 is ROM
(Read-only memory), weighing processing, printing processing,
A control program for controlling display processing, data writing processing, and the like is stored. A random access memory (RAM) 3 is composed of a working area for holding various flags and registers, and a preset data area for recording parts files and the like.

FIG. 3 shows an example of a part file recorded in the preset data area of the RAM 3. As shown in this figure, the component file is composed of columns for storing the component number, component code, component name, and unit weight (columns for storing other data may be added if necessary). . Then, as identification data, the part number (see FIG.
In the example shown in (1), when "1234") is input, the part code (ABC-100) corresponding to the part number, the part name (electrolytic capacitor), and the unit weight (10000) are read.

Since the weight per part may be a very small value depending on its type, the unit weight is stored as the weight of 1000 parts as an internal count value. The internal count value is an anonymous number that is proportional to the actual weight measured by the weighing unit 6 or the weighing unit 7. To convert the internal count value into a pound-based or kilogram-based value, a predetermined value described later is used. Multiply the proportional coefficient (conversion multiplier α for pounds, conversion multiplier β for kilograms),
It is necessary to round the multiplication result to significant digits. For example, in FIG.
In the example shown in FIG. 3, if the conversion multiplier for converting the internal count value of unit weight into the kilogram system (conversion multiplier for kilogram β) is 0.0001, the electrolytic capacitor 1000
Weight per piece is 10000 x 0.0001 = 1 [K
g], and as a result, the weight per piece is 0.001
[Kg].

Next, in FIG. 1, 4 is a printing unit,
The printer 4a (see FIG. 2) is used to print the weight, unit weight, and number. An A / D converter 5 converts the measured value (analog value) obtained by the measuring unit 6 or the measuring unit 7 into the internal count value (digital value) described above. Here, the weighing unit 6 weighs a weight on a weighing pan 6a (see FIG. 2, mainly for weighing a unit weight or a small amount of articles). On the other hand, the weighing unit 7 weighs the weight on the weighing pan 7a (see FIG. 2, mainly for weighing a large amount of articles).

Further, in FIG. 1, 8 is a display section,
The weight, unit weight, number, and various statuses of this device (current unit system, net or gross, connection with peripheral devices, etc.) are displayed. FIG. 4 shows an example of the configuration of the display unit 8 and the operation unit 13 described later. Further, FIG. 5 shows an example of the configuration of the fluorescent display tube used in the display unit 8.

As shown in FIG. 4, the display unit 8 comprises a 20-digit fluorescent display tube, and the first to seventh digits counted from the left of the fluorescent display tube are used as a weight display column 9. . Similarly, the 9th to 13th digits are used as the unit weight display column 10, and the 15th to 20th digits are used as the number display column 11 (the 8th and 14th digits should not be used. No). Further, as shown in FIG. 5, one inverted triangular fluorescent display tube is attached to the lower part of each digit of the display unit 8, and the fluorescent display tube is
As shown in FIG. 4, ON / OFF of various statuses corresponding to the label written on the lower part is displayed. As a result, the inverted triangular fluorescent display tube (see FIG. 4) located at the fourth digit from the left of the display unit 8 is turned off when the current unit system of the present counting scale is the pound system, and the kilogram system is displayed. If it is, it functions as a Kg display lamp 12 that is turned on.

Next, in FIG. 1, reference numeral 13 is an operating portion, which is composed of a ten-key pad 13a and an alphabet key 13b (see FIG. 2). Note that FIG. 4 shows an example of the configuration of the numeric keypad 13a and the alphabet key 13b. In addition to the various keys provided on the conventional counting scale, the operation unit 13 has a new lb as shown in FIG.
A / Kg key 14 is provided.

In the counting balance according to the present embodiment, the specification setting as to whether the counting balance is a pound type balance or a kilogram type balance is preset at the time of factory shipment. This setting is made by a specification setting DIP switch or writing in the nonvolatile RAM. As a result, when the kilogram flag indicating the current unit system is "1", the unit system of this counting scale is the kilogram system,
When the kilogram flag is "0", the unit system of this counting scale is the pound system. Since this specification setting method is a known technique, detailed description will be omitted. Further, the counting scale according to the present embodiment is set as a pound scale and is shipped from the factory. Therefore, the weight display column 9 of the display unit 8 shows pound (lb.) as a unit (FIG. 4).
reference).

Next, the operation of the counting balance having the above structure will be described. FIG. 6 is a flowchart (main routine) showing an outline of the processing of counting work when the present counting scale is used. When the operator turns on the power of the present counter scale, the process proceeds to step S1. In step S1, a part number is input, preset data such as a part code, a part name, and a unit weight is called from a part file, and the process proceeds to step S2.
In step S2, the articles to be weighed are placed on the weighing pan 6a or the weighing pan 7a and weighed, and the process proceeds to step S3. In step S3, the weighing result of step S2 is divided by the unit weight called in step S1, the number of articles on the weighing pan is calculated and displayed, and the process proceeds to step S4.

In step S4, the number calculated in step S3 is printed on a slip such as a delivery slip and a receipt slip together with the weight value and the unit weight value, and the flow advances to step S5. Step S
At 5, it is determined whether or not there is another article to be weighed. If the result of this determination is "NO", that is, if there is another article to be weighed, then the procedure returns to step S1. On the other hand, if this determination result is "YES", that is, if there is no other item to be weighed, the counting operation is ended.

Next, the details of the process of calling the preset data from the parts file (step S1 in FIG. 6) will be described with reference to FIG.
This will be described with reference to the flowchart shown in FIG. When the operator inputs the part number using the ten keys 13a of the operation unit 13, the process proceeds to step S11. In step S11, the part code, the part name, and the unit weight corresponding to the input part number are read from the part file (see FIG. 3) stored in the preset data area of the RAM 3, and R is read.
Store in each register secured in the working area of AM3. Since the method of reading each data based on the above-mentioned part number is a known technique, its detailed description is omitted.

Next, in step S12, it is determined whether or not the value of the kilogram flag (KgF) in the RAM 3 is "1". If the result of this determination is "NO",
If the current setting of the unit system is the pound system, the process proceeds to step S13. When the kilogram flag is "1", it indicates that the currently set unit system is the kilogram system, and when it is "0", it is the pound system. Then, the kilogram flag is initialized to the value of the unit system set at the time of factory shipment when the power is turned on. In step S13, the internal count value UW of the unit weight read in step S11
Is multiplied by the conversion multiplier α for pounds to calculate the unit weight UWp of the pound system, and the process proceeds to step S14. In step S14, the unit weight UWp of the pound system calculated in step S13 is displayed in the unit weight display field 10 of the display unit 8. As a result, the processing in this subroutine ends, and the CPU 1 returns the processing to the main routine.

On the other hand, the judgment result of step S12 is "YE
If "S", that is, if the current setting of the unit system is the kilogram system, the process proceeds to step S15. In step S15, the unit weight internal count value UW read in step S11 is multiplied by the conversion multiplier β for kilogram to calculate the unit weight UWk of the kilogram system, and the process proceeds to step S16. In step S16, step S
The unit weight UWk of the kilogram system calculated in 15 is displayed in the unit weight display field 10 of the display unit 8. As a result, the processing in this subroutine ends, and the CPU 1 returns the processing to the main routine.

Next, details of the process for weighing (step S2 in FIG. 6) will be described with reference to the flowchart shown in FIG. When the CPU 1 reads the weight on the weighing pan from the weighing unit 6 or the weighing unit 7, the process proceeds to step S2.
Proceed to 1. In step S21, the zero point data (weight when the article to be weighed is not placed) is subtracted from the weighing data W ′ read by the weighing section to obtain an internal count value W of the weight of the article.

Next, in step S22, it is determined whether or not the value of the kilogram flag is "1". If the result of this determination is "NO", the flow proceeds to step S23. In step S23, the pound internal weight Wp is calculated by multiplying the internal count value W of the weight calculated in step S21 by the pound conversion multiplier α, and the process proceeds to step S24. In step S24, the weight Wp of the pound system calculated in step S23 is displayed in the weight display field 9 of the display unit 8. As a result, the processing in this subroutine ends, and the CPU 1 returns the processing to the main routine.

On the other hand, the determination result of step S22 is "YE
In the case of "S", the process proceeds to step S25. Step S2
In step 5, the internal count value W of the weight calculated in step S21 is multiplied by the conversion multiplier β for kilogram to calculate the weight Wk of the kilogram system, and the process proceeds to step S26. In step S26, the kilogram-based weight Wk calculated in step S25 is displayed in the weight display field 9 of the display unit 8. As a result, the processing in this subroutine ends, and the CPU 1 returns the processing to the main routine.

Next, details of the process for calculating and displaying the number of articles (step S3 in FIG. 6) will be described with reference to the flowchart shown in FIG. Scale plate 6a or scale plate 7
When the internal count value W of the weight and the internal count value UW of the unit weight are obtained for the article on a, the CPU
The process of 1 proceeds to step S31. In step S31, the internal count value W of weight is divided by the internal count value UW of unit weight, and then the division result is multiplied by 1000 to calculate the number P of articles. The number of items P
Should be displayed as an integer, the number P is rounded to an integer after calculation. Next, in step S32, the number P calculated in step S31 is displayed in the number display field 11 of the display unit 8. As a result, the processing in this subroutine ends, and the CPU 1 returns the processing to the main routine.

The CPU 1 also periodically performs a key scan process on the operation unit 13 while performing the processes shown in FIGS. 6 to 9 to perform a subroutine process corresponding to the operated key. Here, when the lb / Kg key 14 (see FIG. 4) is operated, the process of the CPU 1 proceeds to step P1 of the flowchart (subroutine) shown in FIG. In step P1, it is determined whether or not the value of the above-mentioned kilogram flag is "1". This judgment result is "N
If "O", that is, if the current setting of the unit system is the pound system, the process proceeds to step P2.

In step P2, the value of the kilogram flag is set to "1", and the process proceeds to step P3. Here, changing the value of the kilogram flag from "0" to "1" is performed by l
This is because each time the b / Kg key 14 is pressed, a toggle operation for inverting the value of the kilogram flag is performed. In step P3, the Kg display lamp 12 is turned on,
Go to step P4. In Step P4, the internal count value W of the weight measured by the weighing pan 6a or the weighing pan 7a is multiplied by the conversion multiplier β for kilogram to calculate the kilogram-based weight Wk, and the process proceeds to Step P5.

At step P5, the unit weight internal count value UW is multiplied by the conversion multiplier β for kilogram to calculate the unit weight UWk of the kilogram system, and the routine proceeds to step P6. In step P6, the kilogram-based weight Wk and unit weight UWk calculated in steps P4 and P5 are displayed. As a result, the processing in this subroutine ends, and the CPU 1 returns the processing to the main routine.

On the other hand, the judgment result of step P1 is "YE
If "S", that is, if the current setting of the unit system is the kilogram system, the process proceeds to step P7. Step P
In 7, the value of the kilogram flag is set to "0", and the process proceeds to step P8. In step P3, the Kg display lamp 12
Is turned off, and the process proceeds to step P9. In Step P9, the pound internal weight Wp is calculated by multiplying the internal count value W of the weight by the pound conversion multiplier α.
Go to 0.

In step P10, the internal count value UW of unit weight is multiplied by the conversion multiplier α for pounds,
The unit weight UWp of pound system is calculated, and the process proceeds to step P11. In step P11, the pound weight Wp and the unit weight UWp calculated in steps P9 and P10 are displayed. As a result, the processing in this subroutine ends, and the CPU 1 returns the processing to the main routine. As described above, by performing the processing shown in the flowchart of FIG. 10, each time the lb / Kg key 14 is pressed, the display content of the display unit 8 is changed from the pound system display to the kilogram system display, as shown in FIG. It switches in the opposite direction. At this time, in the kilogram system display, the Kg display lamp 12 is turned on (see ▼ mark in FIG. 11).

As described above, in this embodiment, the unit weight is stored in the parts file as the internal count value, so that the measured value can be calculated at the stage where the measured value of the weighing pan is the internal count value. Since the number is calculated by dividing by the unit weight, the value of the number can be obtained with high accuracy.

However, when the unit weight is stored as the internal count value, since the unit weight is also displayed in the pound system or the kilogram system in this counting scale, each time the unit weight (internal count value) is called from the parts file, It is necessary to convert the unit weight into the unit system currently set, usually,
As the unit weight, the numerical value calculated by the value (internal count value) weighed on the weighing pan 6a is stored in the parts file, but the unit weight is known in advance and the unit weight is manually input using the ten-key pad. -When setting, it is necessary to convert the input unit weight (pound system or kilogram system) into an internal count value and store it.
Since the internal count value has a larger number of significant digits than the pound-based or kilogram-based value, it also has various disadvantages such that the storage capacity for storing the unit weight becomes large.

§2. Second Embodiment Hereinafter, a second embodiment of the present invention will be described with reference to the drawings. In the first embodiment, the unit weight is stored as the internal count value UW in the component file in the RAM 3, but in the present embodiment, the unit weight is the unit system (pound system) numerical value set at the time of factory shipment. It is stored in the part file at. The electrical configuration and the external configuration of the counting balance according to this embodiment are the same as those of the counting balance according to the first embodiment (FIGS. 1 and 2) except for the contents of the control program stored in the ROM. The description is omitted.

Next, the operation of the counting balance having the above configuration will be described. FIG. 12 is a flowchart (main routine) showing an outline of the processing of counting work when the present counting scale is used. The flowchart shown in FIG. 12 is a process of calling preset data from a component file (step S1 ′).
And a process for calculating and displaying the number of articles (step S
3 ') is the same as the flowchart shown in FIG. Therefore, the details of the processing in steps S1 ′ and S3 ′ will be described below, and the description of the other steps in FIG. 12 will be omitted.

First, the details of the process of calling the preset data from the parts file (step S1 'in FIG. 12) will be described.
This will be described with reference to the flowchart shown in FIG.
The flowchart shown in FIG. 13 is the same as the flowchart shown in FIG. 7 except that step S13 is deleted and step S15 is changed to step S15 ′.

That is, the determination result of step S12 is "N
If "O", that is, if the current setting of the unit system is the pound system, the process proceeds to step S14 and step S1.
The unit weight UWp of the pound system read in 1 is displayed on the display unit 8 as it is.

On the other hand, the determination result of step S12 is "YE
If "S", that is, if the current setting of the unit system is the kilogram system, the process proceeds to step S15 '. In step S15 ′, the unit weight UWp of the pound system read in step S11 is multiplied by the conversion multiplier γ for kilogram to calculate the unit weight UWk of the kilogram system, and in step S16, the unit weight of the kilogram system is calculated. UWk is displayed on the display unit 8. It should be noted that while the kilogram conversion multiplier β is a coefficient for converting the internal count value (anonymous number) into a value of the kilogram system, the kilogram conversion multiplier γ
Is a coefficient for converting a value in the pound system into a value in the kilogram system, and is calculated by γ = β / α.

Next, details of the process for calculating and displaying the number of articles (step S3 'in FIG. 12) will be described with reference to the flowchart shown in FIG. The flowchart shown in FIG. 14 is different from the flowchart shown in FIG. 9 in that the number is calculated from a unit weight and a unit weight that are unified into either a pound system or a kilogram system.

That is, in step S30 ', the current setting of the unit system is judged, and if it is the pound system, step S31'.
If it is a kilogram system, the process proceeds to step S31 ″. In step S31 ′, the weight Wp of the pound system is divided by the unit weight UWp of the pound system, and then the division result is multiplied by 1000 to obtain the number P of articles. Note that, like step S31 (see FIG. 9), the number P is rounded to an integer after the calculation. In step S31 ″, the kilogram-based weight Wk is divided by the kilogram-based unit weight UWk,
By multiplying the division result by 1000, the number of articles P
To calculate. The point that the number P is rounded to an integer is the same as in step S31 ′. In step S32, the number P is displayed in the number display field 11 of the display unit 8.

By the way, in this embodiment, similarly to the first embodiment, the CPU 1 periodically performs the key scan processing on the operation unit 13 while performing the processing shown in FIGS. Here, when the lb / Kg key 14 (see FIG. 4) is operated, the process of the CPU 1 proceeds to step P1 of the flowchart (subroutine) shown in FIG. The flowchart shown in FIG. 15 is the same as the flowchart shown in FIG. 10 except that step P10 is deleted and step P5 is changed to step P5 ′.

When the result of the determination in step P1 is "NO" (when the unit system is switched from the pound system to the kilogram system), the unit weight stored in the parts file is the pound system value UWp. It is necessary to multiply UWp by the conversion multiplier γ for kilograms and convert it to the unit weight UWk of the kilogram system (step P5 ').

On the other hand, the determination result of step P1 is "YE
In the case of "S" (when the unit system is switched from the kilogram system to the pound system), the unit weight stored in the parts file is the pound system value UWp.
The step of calculating (the step corresponding to step P10 in FIG. 10) is unnecessary, and the read unit weight UWp
Can be displayed as is.

As described above, in the present embodiment, the number is calculated from the weight and unit weight rounded to the value of pound system or kilogram system, so the number is calculated from the internal count value of the weight and unit weight. The accuracy of the calculated number is lower than that of the first embodiment.

§3. Supplement Although the embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and there are design changes and the like without departing from the scope of the invention. However, it is included in this invention. For example, the above-mentioned first
Also, in the second embodiment, an example is shown in which the unit of weight (and unit weight) in the pound system is pound, but 1 pound or less may be displayed in ounces. The total weight in may be displayed in ounces. Similarly, the display in the kilogram system may be displayed in units of grams instead of kilograms.

Also, in the embodiment, an example of switching the pound system / kilogram system is shown, but the unit system to be switched is not limited to this, and switching to another unit system is also conceivable. Further, it is possible to switch the display unit system not only between two unit systems but also between three or more unit systems. Further, the specific calculation process for obtaining the weight value and the unit weight value in the switched unit system is not limited to the contents described in the first and second embodiments described above. Further, although the counting scale in the embodiment has a printing unit and a printer built therein, the printing unit and the printer may be separate from the main counting scale, and the main counting scale has only a display unit. The printing unit and the printer do not have to be provided. Further, in the embodiment, the display unit and the printing unit respectively display and print the number, the weight value, and the unit weight value.
When only the number and weight values are displayed on the display unit and printing is performed by the printing unit, it is possible to print the unit weight together with the number and weight values. In this case, it goes without saying that the unit system of the unit weight printed by the printing unit is the same as the unit system of the weight value.

Further, in the above-mentioned second embodiment, the example in which the pound-based unit weight is stored in the component file is shown, but similarly, the kilogram-based unit weight is stored in the component file. Some examples are possible. in this case,
Instead of the conversion multiplier γ for kilograms described above, a conversion multiplier δ for pounds that converts values in the kilogram system into values in the pound system
It is conceivable to convert the value of the kilogram system into the value of the pound system by using (= 1 / γ = α / β).

[0050]

As described above, according to the present invention, when the selecting means is operated, the converting means causes the unit weight value together with the weight value to be a numerical value in units of the unit system selected by the selecting means. Convert to. Then, the display or print control means displays the weight value and the unit weight value converted by the conversion means on the display means or prints on the print means.
As a result, the unit systems of the weight value and the unit weight value do not become inconsistent. As a result, even when the weight value and the unit weight value are displayed or printed together with the calculated number, accurate numerical values can be grasped without confusion based on the displayed contents.

According to the fourth aspect of the present invention, the number is calculated based on the numerical value before being rounded to the numerical value of the predetermined unit system, that is, the measurement data used for the internal processing of the present counting scale. Since it can be performed, the number of pieces can be calculated with high accuracy.
