じるという問題があった。However, in such a tableting machine, repeated tableting causes a gradual abrasion of the small-diameter tip portion (lower end portion) of the upper die 6, so that molding is performed. It was easy for the resin tablet to have defective appearance such as protrusions and chips. Then, since it is not clear how many times the tableting is performed until the wear reaches the limit, in the present situation, the wear is judged to be the first time when a defect occurs in the product, and the mold is replaced. Therefore, there has been a problem that the die replacement is delayed and the yield is lowered.

号が出力されるようになっている。In these figures, reference numeral 8 indicates an upper die of a rotary type tableting machine. The upper mold 8 is arranged above a lower mold (not shown), and is pressed and compressed from above the powder material filled in the lower mold, and then is moved upward to move the mold upper limit stopper. It is configured to intermittently move in the horizontal direction while being restricted to a predetermined height by 9. And
A position detection sensor 12 including a light emitting portion 10 and a light receiving portion 11 for the laser light is attached to the sensor mounting bracket 13 and arranged on the horizontal movement path of the upper mold 8. More specifically, when the normal height of the tip of the upper die 8 that is not worn is set at a position of 0.992 (mm), and the wear amount limit value is set to 0.008 (mm), The laser light emitting unit 10 and the light receiving unit 11 move along the movement path of the upper mold 8 so that the object passing in the range from the lower limit value 0.992 (mm) to the upper limit value 1.000 (mm) can be detected. They are arranged opposite to each other. In addition, this position detection sensor 12
Are connected to the digital wear amount display device 15 and the tableting counter 16 via the control device 14, respectively, and the control device 14 is operated by the signal from the position detection sensor 12, resulting in the upper die. The passage of 8 is displayed on the tablet counter 16 as the number of times of tableting, and the displacement from the lower limit value 0.992 (mm) of the tip of the upper die 8 is displayed on the wear amount display device 15 as the wear amount. It has become so. Further, the lower limit value 0.992 (mm) and the upper limit value 1.000 (mm) of the position of the tip of the upper die 8 are set and input in the wear amount display device 15, and the height of the tip of the upper die 8 is set. When the wear amount reaches the upper limit value and the wear amount reaches the limit value 0.008 (mm), the control device 14 outputs an operation stop signal to the tablet machine via the wear amount display device 15. Has become.

に明確に表示されることになる。First, when the position detection sensor 12 detects the passage of the upper die 8 and the position of the tip of the upper die 8, the detection result is output to the control device 14 as an electric signal, and this detection signal is output. The received control device 14 digitally displays the displacement due to wear of the tip of the upper die 8 on the wear amount display device 15 as the wear amount. At the same time, the total number of passes of the upper die 8 is displayed on the tablet counter 16 as the number of times of tableting. And the operation of the tablet machine is continued,
When the displacement of the tip of the upper die 8 due to wear reaches a preset limit value of 0.008 (mm), that is, the upper limit value 1 of the position where the tip of the upper die 8 is input to the wear amount display device 15 ．
When it reaches 000 (mm), the wear amount display device 15 displays the value of the wear amount at that time, and the control device 1
4 determines that the upper die 8 needs to be replaced. Immediately thereafter, the control device 14 outputs a stop signal via the wear amount display device 15 to stop the operation of the tabletting machine. At this time, the control device 14 does not determine that the tip of the upper die 8 has passed, so that the count signal to the tablet counter 16 is not output. Therefore, the number of times of tableting until the wear amount of the tip portion of the upper die 8 reaches the limit value is determined by the tabletting counter 16
Will be clearly displayed.

Then, a stop signal is output to the operation stop mechanism to stop the operation of the tabletting machine in an emergency. However, a buzzer, a light or the like is connected to the output side of the wear amount display device 15 to directly warn the operator. May be issued.
