Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a drug quantitative supply device that continuously supplies drugs such as rectangular tablets and capsules one by one to a packaging machine or the like.

[Conventional technology and its problems]

As a conventional technology for the above quantitative supply device, a circular rotor is installed inside a supply tube formed at the bottom of a supply container, and a plurality of notches are formed in a flange provided at the lower part of the outer periphery of the rotor, and the drug enters the notches. There is a device in which the liquid is discharged from a supply port provided in the bottom plate of a supply cylinder by rotation of a rotor (see Japanese Utility Model Publication No. 34620/1983).

By the way, in the above quantitative supply device, the medicine filled in the supply container is guided to the cutout part of the rotor through the extremely narrow cylindrical space formed between the rotor and the supply cylinder, so that the medicine is not allowed to flow into the cylindrical space. In addition, there is a problem in that the medicine is easily clogged, and bridging of the medicine occurs in the upper part of the space, making it impossible to reliably supply medicine one by one continuously.

[Purpose of invention]

Therefore, the object of this invention is to solve the above-mentioned inconveniences and to provide a drug quantitative supply device that can reliably supply drugs such as capsules and tablets one by one.

[Purpose of invention]

In order to achieve the above object, this invention forms a supply port on the outer periphery of the bottom plate of the supply cylinder provided at the bottom of the supply container, and connects the upper surface of the rotatable rotor installed inside the supply cylinder to the outer periphery of the rotor. The rotor has a tapered surface that slopes downward toward the rotor, and a plurality of pockets are provided at required intervals on the outer periphery of the rotor.
A partition wall between adjacent pockets is provided to protrude from the tapered surface, and an inclined guide wall is provided at the upper part of the inner periphery of the supply cylinder to protrude above the partition wall and guide the medicine to the center of the upper surface of the rotor. The wall is provided with a tongue piece that covers the inner opening between the partition walls on both sides of the pocket that communicates with the supply port.

[Effect]

With the above configuration, the medicine filled inside the supply container is guided by the guide wall and falls to the center of the upper surface of the rotor, and the rotor is rotated and tilted by the rotor's tapered surface. Move to the outer periphery. Since the inner opening between the pair of partition walls faces the direction of movement, the drug smoothly enters the pocket from between the partition walls, and when the pocket matches the supply port,
It is discharged from the supply port.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in FIGS. 1 and 2, a lid 2 is attached to the upper opening of a rectangular supply container 1. As shown in FIGS. Moreover, the bottom plate 3 of the supply container 1 is inclined in one direction,
A circular supply cylinder 4 is provided at the lower part of the slope. The outer periphery of the bottom plate 5 of the supply cylinder 4 is sloped downward, and the supply cylinder 6 is provided on the outer periphery. Further, a rotor 7 is installed inside the supply tube 4, and a rotating shaft 8 provided on the lower surface of the rotor 7 is inserted into an insertion hole 9 formed in the center of the bottom plate 5. A gear 10 is attached to the lower part of the rotating shaft 8, and the gear 10 meshes with a gear 12 attached to the rotating shaft 12 of a motor 11. Therefore, when the motor 11 is driven, the rotor 7 rotates.

The outer circumference of the lower surface of the rotor 7 is an inclined surface that fits the upper surface of the bottom plate 5 of the supply cylinder 4, and the upper surface is a tapered surface 13 that slopes downward toward the outer circumference of the rotor 7. As shown in FIGS. 3 and 4, a plurality of pockets 14 are formed at equal intervals on the outer periphery of the rotor 7, and the partition walls 15 between adjacent pockets 14 rise upward from the tapered surface 13. The inner end of the partition wall 15 is made thin in order to facilitate the smooth flow of the drug that moves along the tapered surface 13 to the outer periphery of the rotor 7 into the pocket 14.

Note that the size of the pocket 14 is appropriately determined depending on the size of the medicine.

A guide wall 16 that extends above the partition wall 15 of the rotor 7 is provided at the upper part of the inner circumference of the supply cylinder 4 .
The upper surface of this guide wall 16 is inclined with the same slope in the same direction as the bottom plate 3 of the supply container 1, and the lower surface of the guide wall 16 is inclined with the same slope in the same direction as the tapered surface 13 of the rotor 7. It is sloping. This guide wall 1
A tongue piece 17 is attached to 6, and the tongue piece 17 is
The inner openings of the pair of partition walls 15 on both sides of the pocket 14 facing the supply port 6 are covered, and when the drug in the pocket 14 is being discharged from the supply port 6, the drug is delivered to the supply port 6 through the pocket 14. This prevents continuous discharge.

Now, there is a medicine A such as a capsule inside the supply container 1.
When the rotor 7 is rotated in the filled state, the drug A falls to the center of the upper surface of the rotor 7 along the slope of the bottom plate 3 and the guide wall 16. At this time, since the rotor 7 is rotating, the medicine smoothly moves to the outer periphery of the rotor 7 due to the rotation of the rotor 7 and the inclination of the tapered surface 13 of the rotor 7, and the drug is transferred to both sides of each pocket 14. It enters into the pocket 14 from the inner opening between the pair of partition walls 15 located at the inner side.

When the pocket 14 coincides with the supply port 6, the medicine A inside the pocket 14 is discharged from the supply port 6. In this case, pocket 1 that coincides with supply port 6
Since the upper part of the pair of partition walls 15 in 4 is covered with a guide wall 16, the drug A in the supply container 1 does not apply a load to the drug A that has entered the pocket 14, and
Since the inner opening between the partition walls 15 is covered with the tongue piece 17, the medicine A does not flow into the supply port 6 through the pocket 14, and the medicine A can be reliably discharged one by one.

As shown in FIGS. 3 and 4, if a cutout surface 18 is provided on the tapered surface 13 of the rotor 7, or a protruding shaft 19 is provided on the tapered surface 13, the rotation of the rotor 7 will cause the cutout surface 18 or the protrusion to Since the shaft 19 pushes up the drug A inside the supply container 1,
Formation of bridges inside the supply container 1 can be prevented, and the medicine A can be smoothly flowed toward the rotor 7.

〔effect〕

As described above, this invention has the upper surface of the rotor 7 as a tapered surface that slopes downward toward the outer periphery, a plurality of pockets are provided in an annular shape on the outer periphery of the rotor, and partition walls between adjacent pockets are provided. Since it is provided so as to protrude from the tapered surface, it is possible to smoothly guide the medicine that falls to the center of the upper surface of the rotor to each pocket.

In addition, since the upper part of the partition wall of the rotor is covered with a guide wall, it is possible to prevent two or more drugs from entering the pocket, and there is no load on the drugs in the pocket from above. The occurrence of bridging can also be prevented. Furthermore, since the tongue piece covers the area between the inner diameter side ends of the pocket that coincide with the supply port, it is possible to prevent the drug from continuously falling from the supply port.

Therefore, medicines such as capsules filled in the supply container can be reliably and continuously supplied one by one.
