Description

Detailed Description of the Invention [Technical Field] The present invention relates to a counting scale that calculates and displays the number of objects to be weighed from the weight value of the objects to be weighed and a preset unit weight of the objects to be weighed.

[Prior Art] Counting scales are mainly used for counting parts and the like when entering and leaving a warehouse. Some of the parts are small parts and parts with large weight.
Considering the wide range of objects to be measured and the need to measure unit weight as accurately as possible in order to perform accurate counting, the counting scale is equipped with multiple weighing sections with different maximum weighing capacities. Some machines use different measuring units depending on the parts to be counted.

Conventionally, in this type of counting scale, it is left up to the operator to decide which of a plurality of weighing sections should be used for weighing. Although a measuring section with a large maximum weighing capacity has a wide measuring range, the error is large in a range where the measured value is small. therefore,
In order to perform a more accurate counting operation, it is necessary to select a weighing section whose weight of the object to be weighed is within the measurable range and whose maximum weighing capacity is small. For example, if there are two weighing units with a maximum weighing capacity of soog and 1kg, if you want to weigh 400g,
It is necessary to select a 0g measuring section, and when weighing 600g, it is necessary to select a 1kg measuring section.

[Problems to be Solved by the Invention] However, since the weight of the object to be weighed is unknown before it is measured, the work of predicting the weight from the number of parts delivered or received and selecting the optimal weighing section is difficult. It requires experience and skill, and if you are not used to it, you may find it difficult to select the appropriate weighing section for the parts to be counted, which may reduce work efficiency.

In addition, there is a problem in that accurate inventory management is not possible due to errors caused by measuring using an inappropriate measuring section and the occurrence of stockouts.

In addition, in the past, the operator had to select the measuring section to be used using the scale switching key, and it was not clear which measuring section was currently selected, making the operation difficult.

This invention was made in view of the above-mentioned problems, and its objectives are to automatically select a weighing section suitable for an object to be weighed, and to determine which weighing section is currently selected. The object of the present invention is to provide a counting scale that can reliably perform the following steps.

[Means for Solving the Problems] The gist of the invention according to claim 1 is to include a plurality of weighing sections, store in advance a unit weight corresponding to a code for identifying an object to be weighed, and input the code. In the counting scale for reading out the stored unit weight by means of a storage means for storing measuring part designation data specifying one of the measuring parts in correspondence with the code, and when the code is input, the measuring scale is read out from the storing means. A selection means for reading corresponding measuring section designation data and selecting one of the measuring sections in response to the reading, and a display means for displaying which measuring section has been selected by the selecting means. The counting scale is characterized by:

The gist of the invention as set forth in claim 2 resides in the counting scale as set forth in claim 1, characterized by comprising a manual operating means for selecting one of the weighing sections according to an operation by an operator.

[Operation] Measuring unit designation data that designates one of the measuring units is stored in the storage means in correspondence with a code that identifies the object to be weighed. When the code is input, the corresponding measuring section designation data is read out from the storage means by the selection means. Accordingly, one of the measuring units is selected by the selection means. The measuring section selected by the selection means is displayed by the display means.

According to a second aspect of the invention, the counting scale according to the first aspect of the invention is provided with a manual operation means for selecting one of the weighing sections according to an operation by an operator.

However, the invention described in claim 1.2 automatically selects a weighing section suitable for the object to be weighed, and makes it possible to reliably determine which weighing section is currently selected.

Next, the operation of this embodiment with the above configuration will be explained.

This embodiment has various modes, and the operation mode differs depending on each mode. Here, each mode will be briefly explained.

The "calling mode" is a mode in which warehousing work, warehousing work, and confirmation (inventory taking) work are performed.

The "inspection mode" is a mode in which each set and stored data is printed out and its contents are checked.

The "setting mode" is a mode in which data is stored in the preset data file 18c, in which the product name, shelf number, unit weight, used scale number, etc. are input and stored in correspondence with the part code.

The "reservation mode" is a mode in which data is stored in the reservation file 18c, in which the number of outgoing items or the number of incoming items is input in correspondence with the part code and is stored.

"Maintenance mode" is a mode for performing various maintenance-related processes.

Next, the counting operation 70- according to this embodiment will be explained using the flowchart shown in FIG. Note that the double-lined portion in each step of the flowchart represents the operator's actions. Furthermore, a description of control related to the rotary rack 21 will be omitted.

First, prior to the following processing, the first . Second operation section 9. By operating IO, data such as product name and scale used in accordance with the part code are stored in the preset data file 18a in the RAM 1g as shown in Figure 6.
Write it down. As a result, the usage scale corresponding to the part code is set.

Step 2
(Step l). Note that in the initial state when the power switch is turned on, it is in the delivery mode, and when it is pressed, it is in the delivery mode. The current mode is displayed on the dot display 7.

In step 2, the operator inputs the part code by operating the numeric keypad, alphabet keys, and function keys. When a part code is input, the CPU 1 reads preset data and total data corresponding to the part code from the part file, and stores them in each register (RAM).
18 working areas). And the product name,
The unit weight, etc. is displayed on the dot display 7 as shown in FIG. 9(a), and the process proceeds to step 3.

The shelf position data is sent to the rotating rack 21 via the rotating rack INF22, and the rotating rack 21 controls the rotation of a predetermined shelf based on the shelf position data.

Step 3. In step 4, among the data read by the CPU II from the predetermined storage area 18a of the RAM 18 according to the part code, data of the usage scale (hereinafter referred to as "SD
”) to determine which scale to select. That is, in step 3, SD is "l"
If so, proceed to step 5, and if SD is not rlJ, proceed to step 4. In step 4, if the SD is "2", the process proceeds to step 6; if the SD is "3", the process proceeds to step 7.

In step 5, CPU 1 inputs the measurement unit IN based on the SD.
A selection signal for the first scale 3 is sent to the selection circuit 12 via F13, 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 II.

The CPU II transfers a signal to the effect that the first scale 3 has been selected from the selection circuit 12 to the dot display 7 to display that fact.

Steps 6 and 7 are also processed in the same way as step 5.

In step 8, the operator looks at the display on the dot display 7, confirms the selected scale, determines whether the scale automatically selected by the selection circuit 12 is appropriate, and determines whether the automatically selected scale is appropriate. If so, proceed to step 10, and if not appropriate, proceed to step 9.

Press to switch to the desired scale. For example, if the quantity to be counted is very large, the third scale 5 with a large scale can be selected, and in the case of confirming the unit weight of the object to be weighed, the small scale can be selected.

In this case, the scale is only changed temporally, and the SD in the preset data is not changed.

In step IO, the operator places the object to be measured (the part with the above part 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 of pieces (
= weight/unit weight) is calculated and displayed on the dot display 7 as shown in FIG. 9 (b).

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

In step 13, if the number of objects to be weighed does not match the target value, the number of objects to be weighed on the selected scale is increased or decreased, and steps 10 to 13 are repeated until the number of objects to be weighed does not match the target value.

The printer 19 prints a warehousing slip when in the warehousing mode and a warehousing system when in the warehousing mode.

In step 15, the number of items in stock, the number of items shipped on the same day, and the number of items received on the same day in the total data are rewritten according to the number of parts received or shipped. The inventory quantity is put into stock receipt mode.

Through each of the above steps, counting work and warehousing/discharging management can be performed.

In the above embodiment, the part code is input for each outgoing (or incoming) operation, but by making a reservation for the work, it is possible to omit inputting the part code each time.

For example, in the reservation mode, as shown in FIG. 7(A), the number of outgoing items (in the case of warehousing work, the number of incoming items) is input and stored in advance in the reservation file 18c in correspondence with the part code. Then set it to call mode and rN
Reserved file 1 by operating the E
Data for one item from 8c (parts code and quantity issued)
are read out in order, and instead of inputting the part code in step S2 of FIG. 8, the shipping process is performed. In addition, Fig. 7 (
B) shows the state after the data in the work reservation file 18c has been sorted (rearranged) in the order of shelf number 9.

In addition, in this embodiment, there are three measuring units: "large (third scale 5)", "medium (second scale 4)", and "small (first scale 3)", among which "medium" and "small" are used. was constructed in one piece and "large" was constructed separately, but it is possible to set the number of weighing sections suitable for carrying out the present invention. The parts can also be provided integrally.

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

In addition, although the configuration was such that only the weighing signal of the scale selected by the selection circuit 12 was input to the CPU II, the weighing signals of other weighing sections, for example, of all the weighing sections were input to the CPU II, and the CPU II could input these weighing signals as appropriate. , may be selected.

It is also possible to store a part image corresponding to a part code, and to display the part image on the dot display 7 as shown in FIG. 11 when the part code is input. With this configuration, by comparing the image with the actual part, it is possible to intuitively confirm whether the part code matches the actual part and prevent work errors.

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

Data specifying the weighing section suitable for weighing the object is stored in advance according to the code of the object to be weighed, so when the operator inputs the code, the weighing section suitable for the object to be weighed is automatically selected. selected.

In this case, code input is an essential operation for setting the unit weight, and no extra operation is required during counting.

Furthermore, since the currently used measuring section is displayed on the display means, it is possible to reliably determine which measuring section is selected.

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