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, calculating the number of articles by dividing the weighing result by the unit weight of the article, and displaying or printing the counted number.

[0002]

2. Description of the Related Art In the United States, both pound-based units and kilogram-based units are used together as weight units. Here, 1 kg = 2.2463 lb (1 lb = 0.453590 kg), and therefore, a weigher capable of switching the unit system (lb / kg) of the weight display by operating a setting switch or a key has been developed. (For example, see Japanese Patent Publication No. Sho 62-30368).

[0003] There are two types of modes in a counting weigher: 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. Conventional counting scales are generally configured to be able to switch between pounds and kilograms when displaying weight in the weight display mode. On the other hand, in the counting mode, the purpose is to count the number. Since the calculated number does not change even if the weight unit system is changed, it is possible to switch between pounds and kilograms. Was not configured.

[0004]

However, since recent counting scales are provided with printing means and issue entry / exit slips at the time of counting work, in many cases the weight value is printed together with the counting result. It is also preferable that the unit system (pound / kilogram) can be switched.
However, in the case of a conventional counting scale, the object to be counted is weighed,
In order to calculate the number by dividing this weighing value by the unit weight stored in advance, as in the case of the conventional weight mode, simply switching the unit system of the weight display, 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, when the printing unit prints the weight value and the unit weight value together with the counting result as described above, there is a problem that the unit systems do not match.

The present invention has been made under such a background, and when a weight unit system such as pounds / kilograms is switched, a weight display unit and a unit weight display unit, or a weight value printing column are provided. It is an object of the present invention to provide a counting scale in which the unit system between the unit and the unit weight value printing column always coincides.

[0006]

【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 counting scale according to a first embodiment of the present invention, and FIG. 2 is a perspective view showing the same external configuration. In these figures, reference numeral 1 denotes a CPU (central processing unit), which controls each unit of the apparatus. 2 is ROM
(Read only memory), weighing process, printing process,
A control program for controlling display processing, data writing processing, and the like is stored. Reference numeral 3 denotes a RAM (random access memory), which comprises a working area for holding various flags and registers, and a preset data area for recording component files and the like.

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

Here, since the weight per component may be very small depending on the type, the unit weight stores the weight of 1000 components as an internal count value. The internal count value is an anonymous number 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 Multiply by the proportionality factor (conversion multiplier α for pounds, conversion multiplier β for kilograms)
The result of the multiplication must be rounded to significant digits. For example, FIG.
In the example shown in (1), if the conversion multiplier (conversion multiplier for kilogram β) for converting the internal count value of the unit weight into the kilogram system is 0.0001, the electrolytic capacitor 1000
The weight per piece is 10,000 × 0.0001 = 1 [K
g], and as a result, the weight per piece is 0.001.
[Kg].

Next, in FIG. 1, reference numeral 4 denotes a printing unit.
The printing of the weight, the unit weight, and the number is performed using the printer 4a (see FIG. 2). Reference numeral 5 denotes an A / D converter, which converts a weighing value (analog value) obtained by the weighing unit 6 or 7 into the above-described internal count value (digital value). Here, the weighing unit 6 weighs the weight on the weighing dish 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 a weighing dish 7a (see FIG. 2, mainly for weighing a large amount of articles).

In FIG. 1, reference numeral 8 denotes a display unit;
The weight, unit weight, number, and various statuses of the apparatus (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. FIG. 5 shows an example of the configuration of a fluorescent display tube used for the display unit 8.

As shown in FIG. 4, the display section 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 ninth to thirteenth digits are used as a unit weight display column 10 and the fifteenth to twentieth digits are used as a number display column 11 (the eighth and fourteenth digits are not used). Zu). As shown in FIG. 5, an inverted triangular fluorescent display tube is provided below 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 described below 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 counting scale is a pound system, and is switched to a kilogram system. In the case of, it functions as a Kg display lamp 12 to be turned on.

Next, in FIG. 1, reference numeral 13 denotes an operation unit, which comprises ten keys 13a and alphabet keys 13b (see FIG. 2). FIG. 4 shows an example of the configuration of the numeric keypad 13a and alphabet keys 13b. Further, in addition to various keys provided on the conventional counting scale, a new lb is provided on the operation unit 13 as shown in FIG.
/ Kg key 14 is provided.

In the counting weigher according to the present embodiment, the specification setting as to whether the counting weigher is a pound scale or a kilogram scale is initially set in advance at the time of factory shipment. This setting is performed by a specification setting dip switch or writing in a nonvolatile RAM. As a result, when the kilogram flag indicating the current unit system is “1”, the unit system of the present balance is a kilogram system,
When the kilogram flag is "0", the unit system of the present balance is a pound system. Since this specification setting method is a known technique, detailed description will be omitted. The counting weigher according to the present embodiment is set as a pound-type weighing scale and shipped from the factory. Therefore, pounds (lb.) are indicated as units in the weight display column 9 of the display unit 8 (FIG. 4).
reference).

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

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

Next, the details of the process of calling the preset data from the component file (step S1 in FIG. 6) are described in FIG.
This will be described with reference to the flowchart shown in FIG. When the operator inputs a 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 inputted part number are read from the part file (see FIG. 3) stored in the preset data area of the RAM 3, and R
It is stored in each register secured in the working area of AM3. The method of reading each data based on the part number is a well-known technique, and a detailed description thereof will be 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 indicates that the unit system 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 a conversion multiplier α for pounds to calculate a unit weight UWp in pounds, 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 column 10 of the display unit 8. Thus, the processing in this subroutine ends, and the CPU 1 returns the processing to the main routine.

On the other hand, if the result of the determination in 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 kilogram-based unit weight UWk is calculated by multiplying the internal count value UW of the unit weight read in step S11 by the conversion multiplier β for kilograms, 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 column 10 of the display unit 8. Thus, the processing in this subroutine ends, and the CPU 1 returns the processing to the main routine.

Next, the details of the process of measuring the weight (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 processing is performed in step S2.
Proceed to 1. In step S21, the zero point data (the weight when there is no article to be weighed) is subtracted from the weighing data W 'read by the weighing unit 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 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 conversion multiplier for pounds α, and the process proceeds to step S24. In step S24, the pound-based weight Wp calculated in step S23 is displayed in the weight display column 9 of the display unit 8. Thus, the processing in this subroutine ends, and the CPU 1 returns the processing to the main routine.

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

Next, the process of calculating and displaying the number of articles (step S3 in FIG. 6) will be described in detail with reference to the flowchart shown in FIG. Weighing pan 6a or weighing pan 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
The process of 1 proceeds to step S31. In step S31, after dividing the internal count value W of the weight by the internal count value UW of the unit weight, the number P of the articles is calculated by multiplying the division result by 1000. The number of articles P
Should be displayed as an integer, so 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 column 11 of the display unit 8. Thus, the processing in this subroutine ends, and the CPU 1 returns the processing to the main routine.

The CPU 1 periodically performs a key scan process on the operation unit 13 while performing the processes shown in FIGS. 6 to 9, and performs a subroutine process corresponding to the operated key. Here, when the lb / Kg key 14 (see FIG. 4) is operated, the processing 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". The result of this determination is “N
If "O", that is, if the current setting of the unit system is the pound system, the process proceeds to Step P2.

At step P2, the value of the kilogram flag is set to "1", and the routine proceeds to step P3. Here, the value of changing the value of the kilogram flag from “0” to “1” is l
This is because a toggle operation for inverting the value of the kilogram flag is performed every time the b / Kg key 14 is pressed once. In step P3, the Kg display lamp 12 is turned on,
Proceed to step P4. In step P4, the kilogram-based weight Wk is calculated by multiplying the internal count value W of the weight measured by the weighing dish 6a or the weighing dish 7a by the conversion multiplier for kilograms β, and the process proceeds to step P5.

In step P5, the unit weight UWk of the kilogram system is calculated by multiplying the internal count value UW of the unit weight by the conversion multiplier for kilogram β, and the program proceeds to step P6. At Step P6, the kilogram weight Wk and the unit weight UWk calculated at Steps P4 and P5 are displayed. Thus, the processing in this subroutine ends, and the CPU 1 returns the processing to the main routine.

On the other hand, if the result of the judgment in 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
At 7, the value of the kilogram flag is set to "0", and the routine goes to Step P8. In step P3, the Kg display lamp 12
And goes to Step P9. In step P9, the internal count value W of the weight is multiplied by the conversion multiplier α for pounds to calculate a pound-based weight Wp.
Go to 0.

In Step P10, the internal count value UW of the unit weight is multiplied by the conversion multiplier α for pounds,
The unit weight UWp of the pound system is calculated, and the program proceeds to Step P11. In step P11, the pound-based weight Wp and the unit weight UWp calculated in step P9 and step P10 are displayed. Thus, 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, every time the lb / Kg key 14 is pressed, the display content of the display unit 8 changes 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 display, the Kg display lamp 12 is turned on (see the ▼ mark shown 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 weighed value of the weighing pan is stored at the stage of the internal count value. Since the number is calculated by dividing by the unit weight, the value of the number is obtained with high accuracy.

However, when the unit weight is stored as an internal count value, the unit weight is also displayed in the pound system or the kilogram system in the present scale. Therefore, every time the unit weight (internal count value) is called from the component file, The unit weight needs to be converted to the unit system currently set, usually
As the unit weight, a numerical value calculated based on the value (internal count value) measured by the weighing pan 6a is stored in the component file, but the unit weight is known in advance, and the unit weight is manually input using the numeric keypad. -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 significant number of significant digits compared to the pound or kilogram value, it has various disadvantages such as an increase in storage capacity for storing unit weight.

§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 parts file in the RAM 3, but in the present embodiment, the unit weight is a unit system (pound system) set at the time of factory shipment. Is stored in the parts file. The electrical configuration and external configuration of the counting scale according to the present embodiment are the same as those of the counting scale according to the first embodiment (FIGS. 1 and 2) except for the contents of the control program stored in the ROM. Description is omitted.

Next, the operation of the counting scale having the above configuration will be described. FIG. 12 is a flowchart (main routine) showing an outline of the processing of the counting operation 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 the process of calculating and displaying the number of articles (step S
Except for 3 ′), it is the same as the flowchart shown in FIG. Accordingly, hereinafter, the details of the processing in step S1 ′ and step S3 ′ will be described, and description of the other steps in FIG. 12 will be omitted.

First, the details of the process of calling the preset data from the component 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, if the result of the determination in 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 proceeds to step S1.
The unit weight UWp of the pound system read in step 1 is displayed on the display unit 8 as it is.

On the other hand, if the result of the determination in 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 kilogram-based unit weight UWk is calculated by multiplying the pound-based unit weight UWp read in step S11 by the kilogram conversion multiplier γ. In step S16, the kilogram-based unit weight UWk is calculated. UWk is displayed on the display unit 8. Note that while the conversion multiplier β for kilograms is a coefficient for converting the internal count value (anonymous number) into a value of a kilogram system, the conversion multiplier γ for kilograms described above is used.
Is a coefficient for converting a value in a pound system to a value in a kilogram system, and is obtained by γ = β / α.

Next, the details of the process of 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 differs from the flowchart shown in FIG. 9 in that the number is calculated from the weight and the unit weight unified into either the pound system or the kilogram system.

That is, in step S30 ', the current setting of the unit system is determined.
In step S31 ', if it is a kilogram system, the process proceeds to step S31'. In step S31 ', after dividing the pound system weight Wp by the pound system unit weight UWp, the result of the division is multiplied by 1000 to obtain the number P of articles. Note that, as in step S31 (see FIG. 9), the number P is rounded to an integer after 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
Is calculated. 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 column 11 of the display unit 8.

In this embodiment, as in the first embodiment, the CPU 1 periodically performs 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 processing 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 part file is the pound system value UWp. It is necessary to multiply UWp by a conversion multiplier for kilogram γ to convert it into a unit weight UWk of a kilogram system (step P5 ′).

On the other hand, if the result of the judgment in step P1 is "YE
In the case of "S" (when the unit system is changed from the kilogram system to the pound system), the unit weight stored in the parts file is the value UWp of the pound system, so the unit weight UWp of the pound system
Is unnecessary (a step corresponding to step P10 in FIG. 10), and the read unit weight UWp
Can be displayed as it is.

As described above, in this embodiment, since the number is calculated from the weight and the unit weight rounded to the pound or kilogram value, the number is calculated from the internal count value of the weight and the unit weight. Compared with the first embodiment, the accuracy of the calculated number is lower.

§3. Supplement Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and there are design changes and the like within a range not departing from the gist of the present invention. Even this is included in the present invention. For example, the first
In the second and the second embodiments, an example in which the display unit of the weight (and the unit weight) in the pound system is pounds has been described. May be displayed in ounces. Similarly, the display in the kilogram system may be displayed in units of grams instead of kilograms.

In this embodiment, an example of switching between the pound system and the kilogram system has been described. However, the unit system to be switched is not limited to this, and switching to another unit system is also conceivable. Further, switching of the display unit system not only between two unit systems but also between three or more unit systems can be considered. Further, the specific arithmetic processing 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. Further, although the counting scale in the embodiment incorporates a printing unit and a printer, the printing unit and the printer may be separate from the main weighing scale, and the main weighing scale has only a display unit. , The printing unit and the printer may not be provided. Further, in the embodiment, the number, weight value and unit weight value are displayed and printed on the display unit and the printing unit, respectively.
It is conceivable to display only the number and weight value on the display unit and to print the unit weight together with the number and weight value when printing is performed by the printing unit. 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-described second embodiment, an example in which the unit weight of the pound system is stored in the parts file has been described. Similarly, the unit weight of the kilogram system is stored in the parts file. There may be some examples. in this case,
Instead of the conversion factor γ for kilograms described above, a conversion multiplier δ for pounds that converts a value in kilograms into a value in pounds is used.
It is conceivable to convert a kilogram-based value into a pound-based value using (= 1 / γ = α / β).
