Description

Description: TECHNICAL FIELD The present invention relates to a counting scale for calculating and displaying the number of objects to be weighed from the weight value of the object to be weighed and a preset unit weight of the object to be weighed.

[Prior Art] A counting scale is mainly used for counting parts and the like when loading and unloading. Considering that there are small parts and parts with a large weight among the parts, and that the objects to be weighed are in a wide range and that it is necessary to measure the unit weight as accurately as possible in order to perform accurate counting, etc. Some scales are provided with a plurality of weighing units having different maximum weighing amounts, and these weighing units are properly used according to the parts to be counted.

Conventionally, in this type of counting balance, it is left to the operator to determine which of a plurality of measuring units is used for measuring. Although the weighing unit with the largest maximum weighing has a wide weighing range, the error is large in the range where the weighing value is small. Therefore, in order to perform a more accurate counting operation, it is necessary to select a weighing unit in which the weight of the object to be weighed is within the measurable range and the maximum weighing amount is small. For example, the maximum weight is 500g and 2 of 1kg.
If there are two weighing units, 5 when weighing 400 g
It is necessary to select the weighing unit of 00g, and when weighing 600g, it is necessary to select the weighing unit of 1kg.

[Problems to be Solved by the Invention] However, since the weight of the object to be weighed is unknown before it is weighed, the work of predicting the weight from the number of delivered or received parts and selecting the optimum weighing unit is If experience and perception are required, and if you are not accustomed to it, it is difficult to select a weighing unit suitable for the parts to be counted, and the work efficiency is reduced.

In addition, there is a problem that an error occurs due to weighing by using an inappropriate weighing unit, and it is impossible to accurately perform inventory management to generate a stockout.

Further, conventionally, there is a problem that it is difficult to perform the work because the operator is not allowed to select the weighing unit to be used by the scale switching key or the display of which weighing unit is currently selected is not clear.

The present invention has been made in view of the above problems, and its object is to automatically select a weighing unit suitable for an object to be weighed and determine which weighing unit is currently selected. Is to provide a counting scale that can reliably perform.

[Means for Solving the Problem] The gist of the invention according to claim 1 is to provide a plurality of weighing units, prestore a unit weight corresponding to a code for identifying an object to be weighed, and input the code. In a counting balance that reads out the unit weight stored by storing the unit weight, a storage unit that stores the weighing unit designation data that designates one of the weighing units in correspondence with the code, and the storage unit that stores the code when the code is input. It is provided with a selection means for reading out the corresponding weighing section designation data and selecting any one of the weighing sections in accordance therewith, and a display means for displaying which is the weighing section selected by the selection means. It exists in a counting scale characterized by the above.

The gist of the invention according to claim 2 resides in the counting balance according to claim 1, characterized in that it is provided with a manual operation means for selecting one of the respective weighing units according to an operation of an operator.

[Operation] The weighing section designation data for designating one of the weighing sections is stored by the storage means in correspondence with the code for identifying the object to be weighed. When the code is input, the corresponding weighing unit designation data is read from the storage unit by the selection unit. In response to this, any one of the respective measuring units is selected by the selecting means. The weighing unit selected by the selection unit is displayed by the display unit.

Next, the flow of counting work according to this embodiment will be described with reference to the flowchart shown in FIG. The double-lined portion in each step of the flowchart represents the action of the operator. Further, description of the control relating to the carousel 21 will be omitted.

First, prior to the following processing, the first and second operating sections 9 and 10 are operated in the setting mode as described above, and the data such as the product name and the used scale corresponding to the part code are stored in the RAM 18 as shown in FIG. Preset data file 18a in
Write in. As a result, the usage scale corresponding to the part code is set.

And the operator Is operated to set the shipping mode or the shipping mode, and the process proceeds to step 2 (step 1). In addition, turn on the power switch
In the initial state when set to N, it is in the shipping mode, Press to enter storage mode. Also, when in the receipt mode Press to enter the shipping mode. At present, the mode is displayed on the dot display 7.

In step 2, the operator operates the ten keys, alphabet keys, and function keys to input the part code. When the part code is input, the CPU 11 reads out preset data and totalized data corresponding to the part code from the part file, and registers the registers (RAM1).
8 working area). Then, the product name, unit weight, etc. are displayed on the dot display 7 as shown in FIG.

The rack position data is sent to the rotary rack 21 via the rotary rack INF 22, and the rotary rack 21 controls the rotation of a predetermined rack based on the rack position data.

In steps 3 and 4, of the data read by the CPU 11 from the predetermined storage area 18a of the RAM 18 in accordance with the component code, the data of the used scale (hereinafter referred to as "S").
Which scale is selected). That is, in step 3, if SD is "1", the process proceeds to step 5, and if SD is not "1", the process proceeds to step 4. In step 4, if SD is "2", the process proceeds to step 6, and if SD is "3", the process proceeds to step 7.

In step 5, the CPU 11 determines the measurement unit INF based on SD.
A selection signal for the first scale 3 is sent to the selection circuit 12 via 13, and the selection circuit 12 selects the first scale 3. At the same time, the weighing signal from the first scale 3 is input to the CPU 11. The CPU 11 transfers a signal indicating that the first scale 3 has been selected from the selection circuit 12 to the dot display 7 to display that effect.

The same processing as in step 5 is performed in steps 6 and 7.

In step 8, the operator looks at the display on the dot display 7 to confirm the selected scale and determines whether or not the scale automatically selected by the selection circuit 12 is acceptable. If the scale automatically selected is appropriate, Go to step 10 and step 9 if not
Proceed to.

In step 9, the operator Press to switch to the desired scale. For example, when the counted amount is very large, the third scale 5 for large weighing is used, and for confirming the unit weight of the object to be weighed, the first scale 3 for small weighing is used.
And so on.

When is pressed, the scale changes in the order shown in FIG. 10 and the scale can be selected.

In this case, the scale is temporarily changed, and the SD in the preset data does not change.

In step 10, the operator places an object to be weighed (a component having the above component code) on the selected scale. As a result, the weight data of the object to be weighed is input to the CPU 11, converted into a weight value, and displayed on the dot display 7.

In step 11, the number (= weight / unit weight) is calculated from the weight data and the unit weight, and the dot display 7
Display as shown in Figure (b).

In step 12, the operator checks the displayed number to see if it matches the target number. If they match, the process proceeds to step 14, and if they do not match, the process proceeds to step 13.

If the number of objects to be weighed does not match the target value in step 13, the processes of steps 10 to 13 are repeated until the objects to be weighed on the selected scale are increased / decreased and match the target value.

In step 14, the operator When is pressed, the printer 19 prints the receipt slip in the receipt mode and the receipt slip in the exit mode.

In step 15, the number of stocks, the number of delivery on the day,
The number of goods received on the day is rewritten according to the number of parts that have been put in or taken out. The number of stock is in the receipt mode, When the number is operated, the number is added, and in the shipping mode, The number when you operated is subtracted.

Through the above steps, counting work and warehousing / delivery management can be performed.

In the above-described embodiment, the component code is input for each one-time delivery (or warehousing) work, but by making a work reservation, it is possible to omit inputting the component code each time.

For example, in the reservation mode, as shown in FIG. 7 (a), the number of deliveries (the number of deliveries in the case of a storing operation) is input and stored in advance in the reservation file 18c corresponding to the part code. After that, set the call mode to "N
Reserved file 18c by operating the "EXT" key
From this item, data for one item (part code and number of warehousing) is sequentially read, and the warehousing process is performed instead of inputting the part code in step S2 of FIG. Incidentally, FIG. 7 (b)
Shows the state after sorting (rearranging) in the order of the shelf numbers of the data of the work reservation file 18c.

In addition, in the present embodiment, there are three weighing units, “large (third scale 5)”, “medium (second scale 4)” and “small (first scale 3)”, of which “medium” and “small”. Was integrally formed, and "large" was separately formed, but it is possible to set the number of measuring units suitable for implementing the present invention,
In addition, the counting scale A may be provided with all the measuring units integrally.

Further, although the rotary rack 21 is connected in the present embodiment, the counting scale A can be used alone.

Further, although the weighing signals of only the scale selected by the selection circuit 12 are input to the CPU 11, other, for example, weighing signals of all weighing units are input to the CPU 11 and the CPU 11 appropriately sends these weighing signals. , May be selected.

It is also possible to store a component image corresponding to the component code, and when the component code is input, display the component image on the dot display 7 as shown in FIG. With this configuration, by comparing the image with the actual product, it is possible to intuitively confirm the match between the part code and the actual part, and prevent work mistakes.

"Effects of the Invention" Since the present invention is configured as described above, it has the effects described below.

Corresponding to the code of the object to be weighed, the data that specifies the weighing unit suitable for weighing this object is stored in advance, so when the operator inputs the code, the weighing unit suitable for the object is automatically Selected.

In this case, the code input is an indispensable operation for setting the unit weight as compared with the related art, and an unnecessary operation is not required during counting work.

Further, since the currently used measuring unit is displayed on the display means, it is possible to surely determine which measuring unit is selected.

As a result, according to the present invention, workability in counting work,
The accuracy can be improved.
