Abstract

PURPOSE:To measure continuously and easily plural articles by providing a means for storing plural-time measurement data and their fetch numbers and a means for accessing all the data or data corresponding to a single or plural numbers which are selected optionally. CONSTITUTION:Weight data on an initial load is fetched thrugh a sensor 1 and an A/D converter 2, an initial zero point is set and stored in RAM9, and weight 0 and the mark of a position 0 of zero-point display 20 are displayed on a display device 19. When a load is placed for the 1st time, an arithmetic part 11 performs arithmetic to display the result, and the weight value and number are stored in the RAM9; when a zero-point switch 21 is pressed, the weight display becomes 0 although the load is still placed and a mark 1 of an indicator 20 is moved. Further, a load is placed successively and similarly to store weight values and numbers. Then the switch 22 is pressed repeatedly to display the stored data from the newest data, and a series of weight values is summed up with a total switch 24 and displayed on the indicator 30.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a measuring device that can be used in a wide range of fields such as commerce, industry, and scientific research.

Configuration of conventional examples and their problems Conventionally, weighing devices have been used to weigh multiple objects (hereinafter referred to as items) one after the other, or to weigh the weight of individual items and the total weight. This required the tedious work of replacing the items on the plate one by one. Continuous weighing was labor-intensive, especially for small or thin items, which were difficult to grasp. Furthermore, when preparing and mixing experimental reagents, paints, feed, cooking materials, etc., there is an inconvenience in that it is not possible to simultaneously measure the weight of individual items and the weight of the mixture.

OBJECT OF THE INVENTION The present invention aims to eliminate the above-mentioned conventional drawbacks, and to facilitate the work of blending, compounding, and continuous weighing of multiple items, and to reduce labor and increase work efficiency. be.

Structure of the Invention Present Inventiveness In order to achieve the above object, when weighing multiple items in succession, the zero point is corrected one after another without removing the items from the weighing pan, and the weight of each item is measured by adding the items. In addition, it is possible to arbitrarily select from among the weighed items and recall and add up the weight, and it is also possible to display the total total.

This allows you to weigh a large number of items one after another, create statistical data, sort parts, and mix various materials while keeping the individually weighed materials on the tray. It is intended to achieve "effects such as increased efficiency."

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to the block diagram of FIG. 1, the external view of FIG. 2, and the flow chart of FIG. 3.

In FIG. 1, 1 is a load sensor that receives a load and converts it into an electrical quantity proportional to the weight, and 2 is an A/D converter that converts an analog input from the load sensor 1 into a digital quantity.

If the load sensor is of a type that detects the load as an amount of change in frequency, the output of the sensor 3 is measured by a frequency counter 4 as an amount of change in frequency proportional to the load. 6 is a microprocessor (CPU), and the inside of the CPU 6 includes an input section 6, a control section 7, and a read-only memory (ROM).
8 and random access memory (RAM) ca, a register section 10, an arithmetic section 11, and an output section 12.
It consists of 13 is a keyboard, and 14 is a display. Furthermore, FIG. 1 shows that output to the printer 16 is possible by adding a printer drive circuit 16.

In FIG. 2, 17 is the main body of the measuring device, 18 is a weighing tray, 19 is a display, and 20 is an indicator such as a zero point display formed using segments other than numbers at the bottom of the display. 21 is a zero point shift switch for resetting the zero point, 22 is a switch to return to the initial zero point, 23 is a switch to call up the weight data once stored,
24 is a total switch that displays the total weight; 26 is a switch that clears the total display or the called weight display;
Display 19 returns to the state it was in before switch 23 or summation switch 24 was operated.

26 is a switch for clearing the contents of a part of the memory.

Numeral keys 27 are used to set the tare amount and alarm conditions, 28 is an alarm set key, and 31 is the position where a display that constantly displays the weight on the plate is added. 3o is an indicator indicating that the total weight is being displayed, 29 is an addition button, and 32 is objects to be measured.

Next, the functions of this measuring device will be explained with reference to the flowchart shown in FIG. When a power switch (not shown) is turned on, weight data based on the initial load is taken in through the sensor 1 and A/D converter 2 (step 1). The input data level at this time is set as the initial zero point, and the memory RA
The information is stored in the M section 9 (step 2). The weight "0" and the mark at the 0" position of the zero point display 20 light up on the weight display (step 3). When the load ■ is added as the first d amount, the input data corresponding to the load is input to the calculation unit 11. The weight value and the fact that it is the first measurement are stored in the RAM section 9 (step 6).Next, press the zero point shift switch 21. The weight is rewritten to a new zero point with the load ■ still placed on the pan (step 7.8).The weight display becomes 0" and moves to the @1" mark on the zero point indicator 20 (step 9.10).Next When the load ■ is placed on the load ■, the weight of the load ■ is displayed and the weight value is stored in memory (steps 11 to 13).

When you press the zero point shift switch 21 again, the zero point is the load■
, ■ is rewritten to the level (step 14.
15). The zero point indicator 2o moves to the @2'' mark (step 16.17). Next, when the load ■ is placed, the weight is similarly displayed and the weight value is memorized (step 1
8-23).

Next, if you want to review the weight of the items that have already been weighed, press the call switch 23 repeatedly, and the weight will be displayed on the display in order from the newest (step, y) 24
, 25). The number of stored data can be recognized by looking at which zero point display indicator is lit. Further, 24 is a total switch that totals and displays the series of weight values weighed up to that point (step 26).
．． 27).

When the total weight is reached, the indicator 30 lights up.

26 is a switch that clears the called display or the total weight display (steps 28 and 29).

Furthermore, when erasing the memory in RAMe, the clear switch 26 is pressed (step 30.31).

In addition, when calculating the total weight by selecting the memorized data, look at the weight and indicator called up with the call switch, press the addition button 29 only when the weight you want to add is displayed, and display the added weight one by one. I can do it. Reference numeral 31 is a place where a display is added to constantly display the total weight inside the memory. Also, when stacking multiple loads, the total weight from the initial zero point is constantly monitored, and an alarm sounds when the maximum weight is exceeded. Further, the upper limit for sounding the alarm can be set in advance in memory using the numerical keys 23 and the alarm center key 26. These series of controls are performed by a program stored in the ROMa.

As described above, according to this embodiment, when weighing multiple items one after another, you can press the zero point shift button to rewrite the zero point, add more items, and continue weighing without having to remove the previous item one by one. . Also, the total weight of the weighed load can be displayed immediately by pressing the total button. Furthermore, it is possible to recall and confirm the data of items that have already been weighed, and to add up only the data that is arbitrarily selected.

Effects of the Invention The present invention has a configuration as described in section 2, which is convenient when repeatedly weighing small items that are difficult to hold by hand, and can improve work efficiency.

It is convenient for measuring all types of mixing and compounding work such as physical, chemical, and chemical materials 2 food materials, feed, etc., and has features such as being able to weigh individual materials and mixtures on a plate at the same time.
