Description

Description: TECHNICAL FIELD The present invention relates to a dispensing device for dispensing a drug which requires sorting by manual sprinkling.

[Prior Art] A medicine packaged in the same medicine bag based on a prescription may include a powder medicine and a fixed-form tablet, as well as an atypical medicine and a medicine having a sticky surface.

Conventional powdered medicines and fixed-sized tablets can be automatically dispensed in the required amount automatically from the storage container by a powdered medicine packaging machine or tablet dispensing device, but non-standard-sized or sticky medicines are automatically dispensed by a machine. It cannot be distributed, and sorting work by hand is required. Therefore, a method is used in which the medicine is sorted into a large number of distribution containers provided in a medicine bucket and the medicine is distributed from the distribution container.

Conventionally, a device described in Japanese Patent Application Laid-Open No. 60-148402 is known as a drug distribution device including the above-mentioned drug bucket.

In this device, a bottom plate that can be opened and closed is attached to each of a large number of distribution rods provided in a medicine bucket, and the medicine bucket is slid on a support base provided with a chute hole into which a lid plate fits. When the container comes to the chute hole, the bottom plate of each distribution container is opened by its own weight so that the medicine inside the distribution container is dropped.

[Problems to be Solved by the Invention]

However, in the above-mentioned conventional structure, in order to drop the medicine stored in all the dispensing basins, the moving stroke of the medicine bucket is at least twice the total length of the dispensing basin so that all the dispensing basins and the chute holes overlap. Size is required. Therefore, a large space is required for the installation of the device, and when the drug dispensing device is to be incorporated into the powder dispensing machine or the tablet packaging machine, the storage space becomes large and the device itself becomes large. .

In addition, when a drug having an adhesive property is stored in the distribution container, the mucus of the drug may adhere to the lid plate and bond the lid plate to the distribution container. In the structure of opening, the lid plate may not be opened while being adhered, and there is a drawback that the drug is not reliably distributed and reliability is poor.

An object of the present invention is to solve the above problems and to provide a drug dispensing device that can be installed in a compact space, can reliably open and close the lid plate, and can perform reliable dispensing. .

[Means for Solving the Problems]

In order to solve the above problems, the present invention provides a medicine bucket that is horizontally supported by a support frame, and arranges a large number of distribution rods penetrating in the upper and lower surfaces in a vertically and horizontally aligned manner, and at the bottom of each of the distribution rods. A lid plate that pivots downward in the same lateral direction with one end as a fulcrum, and a holding means that holds the lid plate in a state of being in close contact with the bottom surface of the distribution container by suction force or elastic force. Below the bucket, a cover plate activating member that spans the entire width of the distribution basin column is provided movably in the lateral direction of the bucket, and the activating member corresponds to each row within one pitch of the distribution basin column. And a plurality of claws whose phases are shifted by equal intervals are attached, and the height of the claws is formed so as to abut the lower surface of each lid plate when the activation member moves in one lateral direction. And the cover plate are brought into contact with each other so that the cover plate retains the holding means. It was constructed to rotate downwardly beyond the range.

In the above structure, the holding means may be a magnet embedded in the bottom surface of the distribution container, and the magnetic attraction of the magnet may bring the lid plate into close contact with the bottom surface of the distribution container.

Further, in the above-mentioned dispensing device, the support tray is positioned above the drug bucket, and the drug tray is detachably attached to the support frame.
On the medicine tray, a large number of sorting basins that penetrate the upper and lower surfaces corresponding to the dispensing buckets of the medicine bucket are formed, and at the bottom of the medicine tray, a shutter that opens and closes the bottom of each sorting basin is slidable. The attached structure can be adopted.

[Action]

In the above apparatus, the lid plate is brought into close contact with the bottom surface of the distribution container by the holding means, and the medicines are sorted into the distribution containers with the bottom of the distribution container closed. When the lid plate actuating member is moved laterally in this state, the lower surface of the lid plate engages with the claws to open the lid plate and drop the medicine.

This lid plate is opened by sequentially opening the lid plates of the distribution basins in a column in accordance with the arrangement of the claws, and when the lid plate actuating member moves laterally by one pitch in the column, the lid plates in the next column are opened in order. To be done.

In the structure described above, all the distribution rods can be opened by moving the cover plate actuating member by the entire width of the row of the distribution rods, so the movement stroke is half that of the conventional structure.

Further, since the claw and the lower surface of the lid plate are engaged with each other to forcibly open the lid plate, it is possible to reliably drop the medicine stored in the distribution container.

On the other hand, behind the support frame 1, a stopper fitting 33 connected to the rotary shaft 6 via a support rod 32 is provided. The stopper fitting 33 is rotatable up and down as shown in FIG. 10. When the support frame 1 is housed in the back side of the base C by driving the rotary shaft 6, the stopper shaft 33 is rotated. The rotation causes the bucket 2 to rotate upward, engage with the hole of the locking metal fitting 12 of the medicine bucket 2, and prevent the bucket 2 from coming out.

This embodiment has the above-mentioned structure, and its operation will be described below.

As shown in FIGS. 1 to 4, in a state where the support frame 1 is pulled out from the base C, the medicine bucket 2 and the medicine tray 3 are attached to the support frame 1, and the sorting tray 18 of the medicine tray 3 is attached.
Then, the medicines to be distributed are sorted by manual operation. In addition,
The medicine tray 3 in which the medicines are sorted in advance may be attached to the support frame 1.

From the above state, when the motor 5 is operated and the support frame 1 is housed inside the base C by driving the pinion 7 of the rotary shaft 6, the stopper metal fitting 33 causes the stopper metal fitting 33 of the medicine bucket 2 to move.
2 to lock the movement of the bucket.

Then, the step motor 27 is operated to move the cover plate starting member 21. In this case, the step motor 27 is
The actuating member 21 is not immediately moved in the opening direction of the cover plate (leftward in FIG. 2), but is initially moved by a predetermined amount in the direction opposite to the opening direction (rightward). This allows
The swing rod 29 swings as shown in FIG.
For sorting the medicine tray 3 for sliding
Is opened, and the medicine in the sorting container 18 drops into the distribution container 13 of the medicine bucket 2.

When the medicine is stored in the distribution container 13 in this way, the step motor 27 rotates in the reverse direction to move the starting member 21 in the opening direction (left direction) of the cover plate. In this case, step motor 2
7 stops the starting member 21 when the claw 28 on the front side of the starting member 21 moves to the left side from the rightmost column of the distributing container 13 by 1/6 of the lateral pitch of the distributing container.

By the movement of the starting member 21 during this period, as shown in FIG. 8, the projection 17 of the front cover plate 15 and the claw 28 in the rightmost column of the distribution container 13 are engaged with each other to open the cover plate 15, and the distribution thereof. The medicine in the container 13 drops.

Next, when the step motor 27 is operated again, the starting member 21 is moved to the left by 1/6 of the lateral pitch of the distribution container 13 and stopped. As a result, the lid plate 15 on the back side and the claw 28 are engaged with each other from the front side, the lid plate 15 is opened, and the medicine in the distribution container 13 falls.

In this way, each time the step motor 27 is operated, the starting member 21 is moved to the left by 1/6 of the lateral pitch of the distribution basin, whereby the lid plates 15 are sequentially opened one by one and all the distribution basins are opened. The drug in 13 is dropped.

When the dispensing container 13 is completely opened and the medicine drops, the step motor 27 rotates in the reverse direction to move the starting member 21 to the left. By this movement, the claw 28 of the starting member 21 abuts against the opened cover plate 15 from the back side and pushes it back.
Is pushed back in the closing direction and is brought into close contact with the bottom surface of the medicine bucket 2 by the attraction force of the magnet 16 to close the distribution container 13. In this way, when the starting member 21 moves to the right end of the support frame 1, all the cover plates 15 are pushed back, and all the distribution basins 1
3 will be closed.

On the other hand, when the stopper fitting 33 is engaged with the locking fitting 12, the medicine bucket 2 is fixed inside the base C, so that when the support frame 1 is pulled out in that state, only the medicine tray 3 is pulled out. . Therefore, the extracted drug tray 3
The drug tray containing the drug is placed above the drug bucket 2 by newly sorting the drug (or replacing it with a new drug tray in which the drug is sorted in advance) and then storing the support frame 1 again in the base C. Can be located at. Therefore, by performing the above-mentioned work while dropping the medicine from the dispensing container 13 of the medicine bucket 2, the dispensing work can be continuously performed.

The holding means for bringing the lid plate into close contact with the bottom surface of the distribution container is not limited to the method using the magnetic attraction force as described above. For example, the elastic clip and its engaging piece on the bottom surface of the lid plate and the distribution container. May be provided, and the both may be coupled by the engagement of the clip. In this case, the connection between the lid plate and the distribution container is
It is preferable that the structure is forcibly performed by the engagement between the claw and the protrusion.

[Effects of the Invention] As described above, according to the present invention, a lid plate actuating member for opening the lid plate of the dispensing container is provided in the lower portion of the medicine bucket, and if the actuating member moves by the entire width of the dispensing container, all Since the distribution container can be opened, the moving stroke is half that of the conventional structure, and the installation space can be significantly reduced.

Also, because the claw of the activation member and the lower surface of the lid plate are brought into contact with each other to forcefully open the lid plate, the lid plate is opened even when the lid plate is adhered with an adhesive substance such as a drug. By doing so, the medicine can be reliably dropped, and highly reliable dispensing work can be performed.

Further, if a magnet is used as a holding means for bringing the lid plate and the distribution container into close contact with each other, the close contact can be ensured and the holding structure can be made compact.

Furthermore, if a drug tray equipped with a sorting container is detachably attached above the drug bucket and the sorting container can be opened and closed by a shutter, the drug can be sorted at the same time as the dispensing work in the drug bucket. Therefore, continuous distribution work is possible, and there is an advantage that high efficiency work can be realized.
