In the medicine dispensing device disclosed in Patent Document 2, a medicine container is taken out from a container shelf by a robot and moved to a vibrating table, and the medicine container is vibrated to drop the powder directly from the medicine container onto a distribution tray. In addition, the weight of the medicine container is monitored by a load cell attached to the shaking table to detect the amount of the powder falling.
The subsequent steps are the same as in the past, and the dispensing tray is continuously rotated at a constant rotational speed to evenly distribute (distribute) the powder in the grooves of the dispensing tray. Then, the scraping plate of the scraping device is dropped into the groove of the distribution tray, the distribution tray is rotated by an angle corresponding to the number of distributions, and the powder for one dose is collected on the front side of the scraping plate, and the powder is scattered by the scraping plate. Is scraped out of the distribution tray, sent to the packaging device, and packaged by the packaging device.
