DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for dispensing column-shaped drugs such as ampules, vials, capsules or elongated tablets.
The present invention relates to a medicine dispensing device that can be taken out one by one.

[0002]

2. Description of the Related Art An ampule dispensing apparatus which stores ampules and takes out a required number of ampules one by one as needed is disclosed in Japanese Utility Model Laid-Open No. 5-86873, Japanese Utility Model Publication No. 6-1.
No. 4753.

In the ampoule dispensing apparatus described in the above publication, the ampules arranged in the cartridge are taken out one by one. Therefore, when the ampules are used up, it is necessary to refill the cartridge with ampules.

At this time, it is necessary to carefully and neatly arrange the ampules in the cartridge one by one, and there is a problem that replenishment is extremely troublesome.

In Japanese Utility Model Laid-Open Publication No. 6-65329, a lower cylinder is rotatably connected to the lower end of an inclined upper cylinder, and an angle member is attached to the inner periphery of the lower cylinder. A discharge port is formed in the bottom plate that closes the lower end opening of the body, and the ampoule that slides down from the upper cylinder into the lower cylinder is machined with an angle material that rotates with the lower cylinder, and is conveyed in the circumferential direction,
An injection dispensing device that discharges the ampule at the position of the discharge port is described.

[0006] In the injection dispensing device, since the ampoule is made with the angle material attached to the inner surface of the lower cylinder and discharged from the discharge port, the posture is kept constant even if the ampoule is randomly inserted into the upper cylinder. It has the characteristic that the ampoule can be easily refilled.

[0007]

By the way, in the above-mentioned injection dispensing device, when the lower cylinder rotates.
When the ampoule passes through the discharge port, the ampule supported by the angle material slides down from the discharge port. There is a risk of narrowing or breakage in position.

An object of the present invention is to provide a medicine dispensing method and a medicine dispensing method which can surely dispense cylindrical medicines such as ampules randomly stored in a medicine storage container one by one without damaging them. It is to provide.

[0009]

In order to solve the above-mentioned problems, in the present invention, a bottom plate is inclined in one direction, and a medicine storage container in which medicines are randomly stored therein, and a one-way container. A scraping device having a large number of scraping plates to be moved, each scraping plate scooping a drug stopped at a lower end portion of the bottom plate in a process of moving upward from below the drug container and transporting the drug upward; and A chute for receiving and discharging the medicine discharged from the scraping plate at the upper part of the scraping device. A configuration is adopted in which only one medicine orthogonal to the inclination direction of the bottom plate can be stably transported upward.

[0010] According to the above construction, the scraping device is driven to move the scraper in one direction, so that the scraper moves upward from the lower side of the drug storage container to the drug storage. The medicine randomly stored in the container can be scooped one by one by each scraper and transported upward. At this time, if the direction of the medicine scooped by the scraper is not orthogonal to the tilt direction of the bottom plate, the drug is naturally discharged from the scraper, and only the drug orthogonal to the tilt direction of the bottom plate is removed by the scraper. It is stably supported and is taken out upward.

Therefore, the medicine can be dispensed from the chute while keeping the direction of the medicine constant.

Here, if a stirrer for stirring the stored medicine is provided in the medicine storage container, the stirred medicine rolls along the inclination of the bottom plate, and the rolling direction is aligned in the longitudinal direction. The plate can almost certainly scoop up the medicine and prevent the scraper from being transported empty.

When a flexible cushioning material is stored in the medicine container, collision between the medicines can be avoided, and damage due to the collision can be prevented.
