In accordance with this, tablets are discharged from the tablet feeder.

Therefore, if the tablet feeder corresponding to the prescription accommodates a sufficient number of tablets, there is no problem, but the number of tablets required for the prescription exceeds the number of tablets accommodated in the tablet feeder. In this case, the tablet discharging and packing operation according to the prescription cannot be executed to the end and will be interrupted midway.

In such a case, even if the tablets are replenished at the time of the interruption, it may not be possible to continue the ejection of the tablets and the packaging operation according to the prescription depending on the ejection at the time of interruption and the packaging state. Not only will the dispensed tablets be wasted until the time of interruption due to the prescription, but the packaging work will not be performed according to the prescription.
There has been a problem that the tablet feeder must be replenished with tablets sufficiently, and then the prescription must be re-entered and executed again.

The present invention solves the problems of the above conventional ones, and when the number of tablets required for prescription exceeds the number of tablets stored in the corresponding tablet feeder, the prescription is put on standby, and It is an object of the present invention to provide a control device for a tablet packaging machine, which can prevent the tablet discharging and packaging operation due to prescription from being interrupted in the middle.

[Means for Solving the Problem] In order to achieve the above object, the present invention provides a tablet component including a large number of tablet feeders and a packaging device for packaging tablets discharged from each tablet feeder in arbitrary number of tablets. In the packaging machine, when the number of tablets required for prescription exceeds the number of tablets accommodated in the corresponding tablet feeder, with a detection device that detects it, and when the detection device makes the prescription stand by, And a processing device for operating the tablet feeder corresponding to the prescription, wherein the processing device is configured to operate the tablet feeder corresponding to the prescription held after the detection device stops detecting. is there.

[Operation] By adopting the above means, the present invention makes it possible to determine the number of tablets required for the prescription even if the prescription for ejecting tablets is transmitted from any tablet feeder. If so, the prescription is put on hold, thereby preventing the prescription from being interrupted during execution.
