Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drug dispensing device capable of taking out ampules, vials, capsules, or elongated medicines such as elongated tablets one by one.

[0002]

2. Description of the Related Art An ampoule dispensing device in which ampules are stored and a necessary number of ampules are taken out one by one is disclosed in Japanese Utility Model Publication No. 5-86873, Japanese Utility Model Publication 6-1.
No. 4753.

By the way, in the ampoule dispensing device described in the above publication, the ampules arranged in the cartridge are taken out one by one. Therefore, when the ampules are exhausted, it is necessary to replenish the cartridges with ampoules.

At this time, it is necessary to carefully and orderly arrange the ampoules in the cartridge one by one, and there is a problem that replenishment is very troublesome.

In Japanese Utility Model Publication No. 6-65329, a lower cylinder is rotatably connected to a lower end of an upper cylinder arranged in an inclined shape, and an angle member is attached to an inner circumference of the lower cylinder to form a lower cylinder. Forming a discharge port on the bottom plate that closes the lower end opening of the body, the ampoule that slides and falls from the upper cylinder to the lower cylinder is lifted up with an angle material that rotates with the lower cylinder and conveyed in the circumferential direction,
An injection dispensing device is described in which the ampoule is discharged at the position of the discharge port.

In the above injection dispensing device, since the ampoule is lifted up by 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 ampule is randomly charged into the upper cylinder. It has a feature that it can be dispensed and the ampoule can be easily replenished.

[0007]

By the way, in the above-mentioned injection dispenser, when the lower cylinder is rotated,
Since the ampoule supported by the angle material slides down from the discharge port, when the ampoule passes through the discharge port, the rear end of the ampoule will be lifted by the angle material that moves in the circumferential direction, and the ampoule will move to the discharge port. There is a risk of narrowing or breaking in position.

An object of the present invention is to provide a drug dispensing device capable of reliably dispensing columnar drugs such as ampoules randomly stored in a drug container without damaging them one by one. It is to be.

[0009]

In order to solve the above-mentioned problems, in the invention of the method, one cylindrical ampoule is used.

In the ampoule storage container that adopts a configuration that provides an ampoule payout device that stops pulling out of the pull, and further stores a large number of ampoules randomly and stirs the stored ampoule, the inside of the ampoule storage container is flexible. It has a structure in which a shock absorbing material is stored to prevent the ampoule from being damaged.

[0011]

With the above configuration, the plurality of push-up members are moved up and down in order from the push-up member on the side of the medicine storage container, whereby the medicine located in the opening in the medicine storage container is pushed up and stirred, The medicine whose longitudinal direction is orthogonal to the inclination direction of the bottom plate is supported by the upper end surface of the push-up member.

When the push-up member rises, the medicine is transferred by the upper end surface of the push-up member located outside the push-up member and sequentially conveyed obliquely outward, and discharged from the upper end face of the outermost push-up member. Is discharged to.

[0013]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 3, a drug container 1 in which a large number of drugs are randomly packed is provided with an opening 2 on one side.
And the bottom plate 3 is inclined toward the opening 2 with a downward slope.

A medicine delivery mechanism 10 for delivering the medicine A obliquely upward is provided on one side of the opening of the medicine container 1.

The drug delivery mechanism 10 is composed of a plurality of plate-like push-up members P _{1 to} P ₄ arranged in parallel with their side surfaces facing each other.

The push-up members P _{1 to} P ₄ are the same as those of the medicine A.
It has a width dimension capable of supporting one in a rollover state. The plurality of push-up members P _{1 to} P ₄ are arranged such that the upper end surface 11 forms an upward staircase toward the direction away from the medicine storage container 1, and the upper end surface 11 of each push-up member P _{1 to} P ₄ is located outside. It is an inclined surface that inclines with a downward slope toward the push-up member.

The plurality of push-up members P _{1 to} P ₄ are moved up and down in order by the lift device 20 from the push-up member P ₁ on the side of the medicine container 1.

In the lifting device 20, the same number of cams 22 as the push-up members P _{1 to} P ₄ are attached to the cam shaft 21, and the push-up member P ₁ is rotated by the cam 22 which rotates together with the cam shaft 21.
Through P ₄ are moved up and down.

When the push-up member P ₁ near the medicine container 1 is lowered to the lower limit position, its upper end surface 11 is held at substantially the same level as the inclined lower part of the bottom plate 3.

The elevating device 20 is not limited to the above structure. For example, the push-up members P _{1 to} P ₄ may be sequentially moved up and down by a crank mechanism.

A discharge chute 30 is provided on one side of the outermost push-up member P ₄ which is provided at a position farthest from the medicine container 1 of the push-up members P _{1 to} P ₄ .

The discharge chute 30 inclines with a downward slope toward the tip, and its rear end is the outermost push-up member P _4.
Is arranged at a position that coincides with the upper limit position of the upper end surface 11 at, or slightly below.

Now, in a state where a large number of drugs A are randomly stored in the drug container 1, the drug transport mechanism 1
When 0 of the push-up member P ₁ to P ₄ from element P ₁ push-up end side inner proximate the drug container 1 is moved up and down in order, near the drug delivery mechanism 10 by vertical movement of the push-up member P ₁ to P ₄ The drug A is stirred.

Here, if the medicine A is agitated, the medicine A may be damaged by collision of the medicines A. Therefore, a soft cushioning material 4 such as a sponge is stored in the medicine container 1 to store the medicine A. It is good to prevent damage.

By the agitation, the medicine A is aligned in the direction in which the longitudinal direction thereof is orthogonal to the inclination of the bottom plate 3, and the medicine A supported by the upper end surfaces 11 of the push-up members P _{1 to} P _4.
As shown in FIGS. 4 (I) to (IV), the push-up members P _{1 to} P ₄ are moved upward, and when the push-up members P _{1 to} P ₄ reach the upper limit position, the upper end surface 1
1 and moves to the upper end surface 11 of the upper-stage-side push-up members P _{1 to} P ₄ , and a plurality of push-up members P ₁
Through the up stairs formed by the upper end surface 11 of P ₄ to P ₄ , they are sequentially transported.

The medicine fed onto the upper end surface 11 of the outermost push-up member P ₄ is sent onto the discharge chute 30 by the rise of the push-up member P _{4 to} the upper limit position.
The discharge chute 30 moves along the inclination and is discharged from the tip of the chute.

The discharge chute 30 is provided with a sensor PH for detecting passage of the medicine A. When the sensor PH detects passage of a preset number of medicines A, the lifting device 20 is stopped and the medicine A is dispensed. Stops.

[0029]

As described above, according to the present invention, a plurality of push-up members are moved up and down in order from the push-up member near the medicine container to the push-up member on the outer side, whereby one push-up member has a single upper end surface. The medicines are supported in the state of being overturned , and the medicines are sequentially conveyed obliquely upward and discharged from the discharge chute. Therefore, the medicines randomly stored in the medicine storage container are continuously transferred one by one with a fixed longitudinal direction. Can be paid out.
