Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powder measuring device used for evaluating physical properties (fluidity, jettability) of powder.

[0002]

2. Description of the Related Art Generally, it is important to fully grasp the flow characteristics and jet characteristics of the powder to be handled when planning, designing, and quality control of the powder processing process. The jettability is evaluated by, for example, the angle of repose and the degree of compression of powder
The physical properties such as the angle of the spatula were used.
When these physical property values of the powder are individually measured using different measuring devices, reproducible general measured values can be obtained due to individual errors and differences in measurement conditions depending on the measurer. Was difficult. Therefore, the flow characteristics of the powder,
Seven types of physical property values that are considered to be the main factors of jet characteristics, that is, angle of repose, compression degree, spatula angle, cohesion degree, collapse angle, dispersity degree,
It has already been proposed that all the measurement of the difference angle be performed mechanically and under a constant condition by a single powder measuring device (see Japanese Patent Publication No. 51-14278).

[0003]

However, although such a powder measuring apparatus can measure various powder physical property values with a single apparatus, the control and arithmetic processing of each part necessary for the measurement is performed in the measuring process. It is necessary for the measurer to perform the manual work individually, and to arrange the data after the measurement, for example, to calculate the physical property values from the measured angle and weight, and to numerically evaluate the fluidity and the jet property. It is necessary to carry out, and further, it is necessary to manually record and save the calculation results, measurement conditions, measurement results, etc. in the measurement process on a dedicated recording paper. For example, when measuring the degree of cohesion, in the measurement process, first, the average apparent specific gravity used to select the sieve into which the powder is put as a sample and the dynamic apparent specific gravity used to set the vibration time of the selected sieve It is necessary to calculate each with an electronic desk calculator, etc., and to select and set it, and after the measurement, substitute the measured value recorded on the recording paper into a predetermined mathematical formula to calculate the cohesion degree. It was necessary to perform index conversion for liquidity evaluation. Therefore, the measurement work is complicated, the workability is poor, and the time required for the measurement is long. The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a powder measuring device capable of simplifying the measurement work and shortening the measurement time.

The control means controls print output by a printer electrically connected to the apparatus main body, and outputs measurement results to an information processing device for data management electrically connected to the apparatus main body. Is also controlled.
Specifically, the measuring means is an angle measuring jig that rotates and drives an angle measuring arm with a pulse motor so as to be parallel to the inclined surface of the deposited sample powder, and the sample powder is electrically connected to the apparatus main body. The control means includes a driving control of the pulse motor by the driving pulse and the calculation of the angle at the parallel position of the angle measuring arm by counting the number of the driving pulses, and the weighing result of the electronic balance is automatically measured. It is a microcomputer (hereinafter, referred to as "microcomputer") that performs the arithmetic processing necessary to measure the physical properties of the powder.
Further, the measuring means includes a repose angle, a collapse angle measuring part, a loosening / solidifying apparent specific gravity measuring part, a cohesion measuring part, a spatula angle measuring part, and a dispersity measuring part. The measured value obtained by the measurement at each measuring section is replaced with a predetermined numerical value based on the conversion table stored in the memory, and the fluidity and jettability of the sample powder are numerically calculated.

[0005]

With this structure, the control and arithmetic processing required for measurement at each measuring section are automatically performed by the microcomputer during the measurement process, and the automatically recorded measurement values are the same. Substitution with standard numerical value (in this case, index), numerical calculation of fluidity and jettability of sample powder, and output to printer or information processing device (for example, personal computer) are performed automatically. It will be.

When the key 105 is pressed, the display ends. Incidentally, these measurement results are transferred to the personal computer 129 in the online state at any time, and the personal computer 129 side manages the data. Here, if each measurement necessary for evaluating the fluidity is not performed, "Input Value for Flow. Index. Ready = [SET]" is displayed on the LCD 92 when the comprehensive evaluation key 102 is pressed. It will be. Therefore, the SET key 103 is pressed, and the compression degree, the angle of repose, the spatula angle, and the cohesion degree (or the uniformity degree) obtained from the loose apparent specific gravity and the solid apparent specific gravity are sequentially input by the numerical keys 104 according to the display on the LCD 92.
When registered with the NT key 106, the liquidity index and the degree of liquidity are similarly displayed on the LCD 92. Then, when the SET key 103 is pressed from this state and each measurement required for evaluation of the jet property is not performed, the LC
"Input Value for Flood. Index. Ready = [SET]" is displayed on D92. Therefore, press the SET key 103,
When the collapse angle and the degree of dispersion are sequentially input according to the display on the LCD 92 with the numerical key 104 and registered with the ENT key 106, L
Similarly, the CD 92 displays the jet flow index and the degree of jet flow. Then, when data is registered by the ENT key 106 by mistake in an inappropriate place such as when measuring an angle or a weight, the data at that time is written in the memory 130 as a measured value, which is a problem. Therefore, it is necessary to erase the data, and the erasing operation is first performed by the LEDs 93A to 10 of the keys 93 to 102.
When the CLR key 105 is pressed in the measurement completed state where 2A disappears, the message "Select Measurement Data Clear Function" is displayed on the LCD 92 only while the key is pressed. Then, when any key of the measurement item selection section 91A for which data erasure is desired, such as the angle of repose key 93, is pressed in this pressed state, the LCD 92 displays “Angle repose Data Clear Yes = [CLR] No = [ENT]. Is displayed, and when the CLR key 105 to be erased in this case is pressed in accordance with this display, the data when the angle of repose key 93 is previously pressed is erased. If you stop pressing the CLR key 105 without pressing the angle of repose key 93,
After the power switch 1 is turned on, the display “Select Measurement Function” is displayed when the initial settings such as the date are completed. If the comprehensive evaluation key 102 is pressed while the CLR key 105 is pressed in the measurement completion state, all data (excluding the index conversion table and evaluation data) in the memory 130 will be erased in the initial setting state after the power is turned on.

As described above, in the present embodiment, the handle 26 and the moving knob 39 are used to manually move the elevating table 23 for measuring the spatula angle and the angle measuring arm 38 in the vertical and horizontal directions. However, a motor and a position detection sensor may be combined and automatically performed under the control of the microcomputer 123. Further, in the present embodiment, one angle measuring arm 38 is arranged in parallel with the ridgeline of the powder deposition layer to measure its inclination angle, but a plurality of light emission is performed as shown in FIGS. Diode 1
45 and the phototransistor 146 are respectively disposed between the two angle measuring arms 38A and 38B so that the deposition layer is located parallel to each other, that is, the phototransistor 146 is provided with or without the output. Good, if this is done, there is no risk that the angle measurement arm 38 touches and the deposited layer collapses. Further, in the present embodiment, a manostar gauge is used as the display meter 90 for preventing the deterioration of the dust removal function, but the microcomputer 12 measures the pressure loss in the dust removal filter 82.
Alternatively, the data may be read in 3 and digitally displayed. In addition, the suction blower 84 automatically operates when the measurement is started, and the power of the suction blower 84 can be controlled to be turned off when the measurement is completed.
