And a load cell 32 that outputs a voltage according to the tablet placed on the balance pan 31. The balance plate 31 is flush with the upper surface of the tablet moving rail 60, so that the tablet whose weight has been measured can be smoothly moved to the thickness measurement region 40a.

The hardness pusher 54 is provided. In this embodiment, by counting the number of drive pulses for the pulse motor 51, the tablet diameter can be measured before the hardness measurement. The hardness measurement measures the breaking hardness indicated by the pressure required to break the tablet, and a voltage signal is output from the compression load cell 53 to the measurement control unit 10 corresponding to the pressure. The tablet is broken by performing the hardness measurement, and the broken pieces of the tablet are dropped from the tip of the tablet moving rail 60 to the split tablet box (not shown) by the tablet feeding metal fitting 70 after the measurement is completed.

In the hardness measuring area 50a, a groove 63 for positioning the tablet is provided on the upper surface of the tablet moving rail 60. That is, in the case of a substantially elliptical tablet such as a track field, the orientation of the tablet may be changed by being pushed by the hardness pusher 54. Therefore, the tablet is transferred so that the longitudinal direction of the tablet coincides with the groove 63,

It is possible to reliably prevent the tablet from swinging in the horizontal direction and floating in the vertical direction. In this way, the hardness can be measured with the tablet positioned in the correct measuring direction, so the directions in which the tablets are broken can be made uniform, and as a result, erroneous measurement of hardness due to different breaking directions can be prevented. can do.

The position of can be adjusted. That is, by adjusting the position of the front plate 73, the front end surface portion 71a
The depth dimension of the tablet changes, and various tablets having different sizes, such as elliptical shapes, can be supported by the front end surface portion 71a and the front surface of the hanging portion 73b and aligned and transported in the same direction. The tablet feeding fitting 70 is configured to measure the tablets in each measurement area 30.
A, 40a, and 50a are conveyed, but during measurement, they stand by at the position on the home position side in the vicinity of the measurement area, and then operate again to convey tablets.

In this embodiment, prior to the normal measurement, teaching is performed to input a reference value for determining whether or not the measurement result is correct. Teaching is an operation of causing the device to recognize the reference value of the tablet in order to determine the measured value within the standard of the tablets to be measured, and is performed using a reference tablet as an example. The weight, thickness, diameter, and hardness measurement values measured during teaching are measured as reference setting values by operating the push button switch 12 when the operator determines that the measurements are correct during measurement. It is registered in the control unit 10. When the actual tablet measurement is started, the measurement control unit 10 sets a range of ± 10% with respect to this reference setting value as a reference value, and for measurement values within the range of this reference value, As the in-standard data, data processing for average value, maximum value, minimum value, standard deviation, etc. is performed. On the contrary, for tablets that show a measured value that is larger or smaller than the set reference value,
For example, it is excluded from the data processing as a measurement abnormality due to a handling error during the measurement such as a part of the tablet being chipped or the placement direction being wrong. In this way, by teaching using the standard reference tablets,
For example, a keyboard as an input device for inputting a numerical value or the like is not required, the device can be downsized and simplified, and a data input error caused by an erroneous key input operation can be eliminated. Therefore, accuracy in data processing can be improved.

In this way, in the measuring device, it is necessary to calibrate periodically in order to always carry out accurate measurement. The calibration work is performed by using a reference weight as a reference weight object for weight measurement, a reference gauge as a reference dimension object for thickness measurement, and a reference load cell as a reference hardness object for hardness measurement. It Then, the respective calibration results are printed and output by the printer 19.

The weight measuring mechanism 30 is calibrated by the procedure shown in FIG.

First, the proofreader operates the push button switch 12 to select the calibration mode. The fact that the measurement control unit 10 is in the same mode is displayed on the display 11 as "weight calibration", and the tare erase of the balance pan 31 of the weight measuring mechanism 30 is executed. When the tare erase is completed, a display is displayed instructing that the specified reference weight, which is the DUT in this case, be placed. The calibrator places the reference weight of the displayed weight on the balance pan 31 (step S
1). When the reference weight is placed on the balance pan 31, its weight is measured and the measured value is displayed on the display 11 (step S2). When the weight measurement is completed, the measurement control unit 10
The measurement accuracy range data stored in the ROM 13 is compared with the measurement value to determine whether the measurement value is within the measurement accuracy range (step S3). If the result of determination is that the measured value is outside the measurement accuracy range, NG (no) is displayed (step S4), and if it is within the measurement accuracy range, GOOD (good) is displayed (step S5). Next, it is determined whether or not the determination of the measurement value has been completed using the three fixed-point reference weights, that is, the three reference weights having different weights (step S6). If so, it is determined whether or not all the determination results of the three fixed points are within the measurement accuracy range (step S7). If all the determination results of the three fixed points are good, this calibration is determined to be successful, the calibration result is printed out together with the measured value (step S8), and the calibration of the weight measuring mechanism 30 is completed. If even one of the three fixed points is not acceptable, the result is rejected, and the result is determined by the printer 19
To print out. The determination of pass / fail and the printout of the result are similarly executed for the remaining thickness, diameter and hardness calibrations.

Next, the thickness measuring mechanism 40 is calibrated, the display 11 indicates "thickness calibration", and the contact point 41a of the thickness sensor 41 descends and comes into contact with the tablet moving rail 60, so that a zero point is taken. Is performed. Upon completion of zeroing, a display for instructing to mount a prescribed reference thickness gauge is displayed on the display 11 (step S11). When the reference thickness gauge is placed on the thickness measurement region 40a, the thickness is measured (step S12). When the thickness measurement is completed, it is determined whether or not the measured value is within the measurement accuracy range, as in the case of the weight measurement (step S13). If the result of determination is that the measured value is outside the measurement accuracy range, NG (no) is displayed (step S14), and if it is within the measurement accuracy range, GOOD
(Good) is displayed (step S15). Next, it is judged whether or not the judgment of the measurement value is completed by the three fixed point reference gauges, that is, the three reference gauges having different thicknesses (step S
6) If not completed, the process returns to step S11, and if completed, it is determined whether or not all the determination results of the three fixed points are within the measurement accuracy range (step S17). If all the determination results of the three fixed points are good, this calibration is determined to be successful, the calibration result is printed out together with the measured value (step S18), and the calibration of the thickness measuring mechanism 40 is completed.

When the thickness measurement is completed, the display 11
20 mm after displaying "Diameter calibration" on
The reference gauge is used as the tablet moving rail 60 of the hardness measurement area 50a.
Display the instruction to place it on the top surface of. According to the display, the proofreader places the 20 mm reference gauge on the tablet moving rail 60 with the hardness receiver 52 in contact with the hardness receiver 52 (step S31). Push button switch 1 in this state
2 is operated, the measurement control unit 10 causes the pulse motor 51
Is driven to advance the hardness pusher 54 from its home position until it abuts the 20 mm reference gauge, and the number of drive pulses at that time is counted (step S32). The contact of the hardness pusher 54 is detected by the rapid change in the voltage signal corresponding to the pressure output from the compression load cell 53. That is, after driving the pulse motor 51, the voltage signal is 0 during forward movement, but the hardness pusher 54
When the abutting contacts, the compression load cell 53 is compressed, and the voltage signal rapidly increases. When this voltage signal becomes 0 or more at the time when, for example, 3 pulses are counted from the start of the change, it is determined that the hardness pusher 54 is in contact (step S33). The number of drive pulses required to advance the hardness pusher 54 to this position is temporarily stored.

When the measurement of the moving distance to the 20 mm reference gauge is completed, an instruction to put the 5 mm reference gauge is displayed. Similar to the case of the 20 mm reference gauge, when the 5 mm reference gauge is placed (step S34) and the push button switch 12 is operated, the hardness pusher 54 moves from the home position until it abuts the 5 mm reference gauge.
During that time, the number of drive pulses is counted (step S35), it is detected that the hardness pusher 54 has come into contact with the 5 mm reference gauge due to a change in the voltage signal of the compression load cell 53, and the number of drive pulses counted so far is temporarily stored. To do.
After that, the difference in gauge thickness between the 5 mm reference gauge and the 20 mm reference gauge is divided by the difference in the temporarily stored number of drive pulses to calculate the moving distance per drive pulse (step S37). By this series of operations, the movement amount per drive pulse is calibrated prior to the diameter calibration.

When the calculation process of the moving distance, that is, the calibration of the moving amount per one driving pulse is completed, the measurement control unit 10 displays the instruction to mount the reference gauge. When the first reference gauge is placed according to the display and the push button switch 12 is operated (step S38), the hardness pusher 54 is actuated, and the diameter of the first reference gauge is determined by the number of drive pulses during contact with the first reference gauge. Measure and ROM1
The measurement accuracy range data for the diameter stored in 3 is compared with the measurement value to determine whether the measurement value is within the measurement accuracy range for the gauge value of the first reference gauge (step S).
39). N if the measured value is out of the measurement accuracy range
G (no) is displayed (step S40), and GOOD (good) is displayed when it is within the measurement accuracy range (step S4).
1). Next, it is determined whether or not the determination of the measurement value has been completed using the three fixed-point reference gauges, that is, the three reference gauges having different diameters (step S42). If not, the process returns to step S38 and ends. If so, it is determined whether or not all the determination results of the three fixed points are within the measurement accuracy range (step S43). If all the determination results of the three fixed points are good, this calibration is determined to be successful, and the calibration result is printed out together with the measured value (step S44), and the hardness measuring mechanism 5
The calibration of the diameter measurement at 0 is completed.

After that, the display 11 displays "hardness calibration". When calibrating the hardness measurement in the hardness measuring mechanism 50, the reference strain gauge 80 with a communication function is connected to the communication port 18 of the measurement control unit 10. After preparation, set the reference load cell to the hardness measurement area 5
0a (step S51). When the push button switch 12 is operated, a drive pulse is output to the pulse motor 51 to activate the hardness pusher 54, and after contacting the reference load cell, the voltage signal from the compression load cell 53 becomes constant, that is, the hardness pusher 54 The hardness pusher 54 is advanced until the pressure pressing the reference load cell reaches a constant value (step S52). The measured hardness (detection pressure) is read based on the voltage signal from the compression load cell 53 that has a constant value (step S53), and it is determined whether or not the measured hardness has a constant value (fixed point pressure).
When the measured hardness does not change, the fixed point pressure is in effect, so the operation of the hardness pusher 54 is stopped (step S5).
5). If the measured hardness has changed, that is, if the measured hardness has not reached a certain value, the process returns to step S52 and the hardness pusher 54 is further advanced.

Here, even if the specified pressure is applied to the reference load cell, there is a possibility of overrun, so the hardness pusher 5
After stopping 4, the measured hardness is read again (step S56). Next, the measurement control unit 1 via the communication port 18
The reference hardness (peak pressure), which is the maximum measured value from the reference strain gauge 80 based on the reference voltage signal of the reference load cell input to 0, is read and held (step S57),
The measured hardness and the reference hardness are compared (step S58).
As a result of the comparison, the read-out measurement hardness is the standard hardness ROM1.
If it is within the range of the measurement accuracy range data stored in 3, the GOOD (good) is displayed (step S59), and if it is out of the measurement accuracy range, NG (no) is displayed (step S60). Next, it is determined whether or not the determination of the measurement value has been completed by the three fixed point reference load cells, that is, the three reference load cells having different diameters (step S61). If not, the process returns to step S52 and ends. If so, it is determined whether or not all the determination results of the three fixed points are within the measurement accuracy range (step S62). If all the determination results of the three fixed points are good, this calibration is determined to be acceptable, and the calibration result is printed out together with the measured value (step S6).
3) The calibration of the diameter measurement in the hardness measuring mechanism 50 is completed.

As described above, the calibration results of the weight measuring mechanism 30, the thickness measuring mechanism 40 and the hardness measuring mechanism 50 are as follows.
Since it is printed out by the printer 19 regardless of whether it is good or bad, it is not necessary for the proofreader who is performing the proofreading to record the proofreading result, the proofreading work can be simplified, and the proofreading record is fabricated. Becomes impossible,
Further, since no erroneous writing occurs, the reliability of the calibration record can be improved.

Further, since the hardness is calibrated using the standard load cell, it is not necessary to prepare a standard measurement object such as a tablet that is destroyed each time, and the calibration can be repeatedly carried out. Therefore, the cost for hardness calibration can be kept low.

In addition to tablets, the molded product may be confectionery such as candy or chocolate formed into particles.

The present invention is not limited to the embodiment described above.

Besides, the configuration of each part is not limited to the illustrated example, and various modifications can be made without departing from the spirit of the present invention.

[0036]

The present invention is embodied in the form described above and has the following effects.

Since the measured value judging means judges whether the measured value is good or bad, it is possible to prevent calibration failure due to erroneous judgment. In addition, since it is not necessary to judge the measured value and make a record thereof, the calibration work can be simplified.

When the breaking hardness is measured by the pressing means, the pressing operation of the pressing means is stopped when the measured value output from the hardness measuring means reaches a constant value, so that the reference measurement object is not destroyed. The breaking strength can be measured. In this case, by using the reference load cell as the reference measurement object, the reference measurement object can be repeatedly used for the calibration work.

In addition, when the pressing means is provided with the pressing element and the step motor and the radial dimension of the molded body is measured, the hardness measuring means can measure two kinds of parameters. Therefore, the number of measurement items can be increased and the size of the entire device can be kept small.

Further, the measured value and the comparison result are displayed on the optical display immediately after that, and the displayed contents are printed out by the printer, so that misidentification and erroneous writing can be surely prevented.
