Description

  The present invention relates to a partition plate unit applied to a powder supply mechanism configured to temporarily hold and store a powder charged from above and to drop the held powder downward.

In medical institutions such as hospitals and pharmacies, a predetermined amount of powdered medicine is routinely performed based on a prescription.
In order to increase the efficiency of such packaging work, powder medicine packaging devices have been conventionally used.

  The powder dispensing device is disposed below the powder supply mechanism, and a powder supply mechanism for temporarily holding and storing a predetermined amount of powder charged from above and dropping the stored powder downward. And a powder splitting mechanism for splitting and holding the predetermined amount of powder into a predetermined number, and a packaging mechanism disposed below the powder splitting mechanism.

  Specifically, the powder supply mechanism has a long fixed plate and a long movable plate that are arranged so that the longitudinal directions thereof are in the same direction. The long movable plate takes a closed position for forming a powder storage space to be poured from above while cooperating with the long fixed plate, and an open position for dropping the powder in the storage space downward. As can be obtained, it can be swung around the pivot shaft along the longitudinal direction.

  By providing such a configuration, the powder supply mechanism is configured so that the powder is supplied from above in a state where the long movable plate is positioned at the closed position, and after the upper surface of the powder is leveled, the long movable plate is By positioning in the open position, the powder can be supplied to the subsequent powder dividing mechanism.

  By the way, the powder supply mechanism is provided with a partition plate that is movable in the longitudinal direction with respect to the long fixed plate in order to be able to adjust the length of the storage space in the longitudinal direction according to the number of divisions. ing.

  As described above, since the partition plate partitions the storage space, the partition plate needs to be joined to each inner surface of the long fixed plate and the long movable plate that define the storage space. It is also required not to hinder the swinging motion of the long movable plate.

In order to meet such a demand, for example, Patent Document 1 proposes a configuration in which an auxiliary plate is pivotally attached to a partition plate.
In the configuration disclosed in Patent Document 1, the partition plate is configured such that a flank is defined between the inner surface of the long movable plate in the closed position, and the auxiliary plate is closed so as to close the flank. Is attached to the partition plate, so that the accommodation space can be effectively partitioned without hindering the swinging motion of the long movable plate.

Thus, although the structure of the said patent document 1 is useful, on the other hand, it had a problem in the following point.
That is, since the partition plate and the auxiliary plate can be moved relative to each other as described above, there is a possibility that the powdered medicine may enter the contact portion between them.
It is preferable to remove the powder that has entered between the partition plate and the auxiliary plate for each prescription because it mixes with other subsequent powder dividing operations and causes a quantity error.
In particular, when different types of powders are continuously divided, if a powder that has entered between the partition plate and the auxiliary plate is mixed into the powder of the next stage as a residual powder, a dispensing error occurs. Therefore, it is necessary to remove the residual powder sufficiently.

Hereinafter, an embodiment of a partition plate unit according to the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a perspective view of a medicine packaging device 100 including a powder supply mechanism 50 to which the partition unit 1 according to the present embodiment is applied.

The medicine packaging device 100 includes the powder supply mechanism 50, a powder dividing mechanism (not shown) disposed below the powder supply mechanism 50, and a packaging mechanism disposed below the drug dividing mechanism. The powder to be fed into the powder supply mechanism is equally divided into a predetermined number, and the equally divided powder can be individually packaged.
In the figure, reference numeral 90 denotes a tablet dividing mechanism provided in the medicine packaging device 100. The medicine packaging device 100 is capable of packaging tablets in addition to powder.

FIG. 2A is a cross-sectional view taken along the line II-II in FIG. 1 and shows a vertical cross-sectional view of the powder supply mechanism 50 according to the present embodiment. FIG. 2B shows a schematic plan view of the powder supply mechanism 50.
As shown in FIGS. 1 and 2, the powder supply mechanism 50 includes a long fixed plate 60 and a long movable plate 70 that are arranged so that their longitudinal directions are in the same direction.

The long fixing plate 60 is fixed to a fixing member such as a frame in the medicine packaging device 100.
On the other hand, the long movable plate 70 is supported by the fixed member so as to be able to swing around a pivot shaft 70a along the longitudinal direction.
For example, the long movable plate 70 can include a main body portion 71 extending along the longitudinal direction, and an extending portion 72 extending in a direction orthogonal to both end portions of the main body portion 71. The pivot shaft 70a can be inserted through 72.

  Specifically, the long movable plate 70 is formed in a closed position (FIG. 2 (FIG. 2)) around the pivot shaft 70a to form a powder containing space S to be poured from above under cooperation with the long fixed plate 60. A solid line a) and an open position (two-dot chain line in FIG. 2B) where the powdered medicine in the storage space S is dropped can be taken.

That is, the powder supply mechanism 50 moves upward in the accommodation space S defined by the long movable plate 70 and the long fixed plate 60 in a state where the long movable plate 70 is located at the closed position. It is designed to temporarily store powder medicines that are put in. Then, after leveling the upper surface of the powder charged in the storage space S, the long movable plate 70 is positioned at the open position, whereby a predetermined amount of powder is applied to the powder dividing mechanism disposed below. It can be supplied uniformly.
In addition to the long fixed plate 60 and the long movable plate 70, the powder supply mechanism 50 includes a pair of end plates 80a and 80b that block between the longitudinal end portions of both.

The partition plate unit 1 that adjusts the length of the storage space S in the longitudinal direction is further attached to the powder supply mechanism 50.

That is, the storage space S is defined by the long fixed plate 60, the long movable plate 70, one of the pair of end plates 80a and the partition plate unit 1, and the partition plate unit 1 The length of the accommodation space S can be adjusted by sliding the slidable in the longitudinal direction.

  Specifically, the partition plate unit 1 is attached to the long fixed plate 50 so as to be movable in the longitudinal direction, and adjusts the length of the storage space S in the longitudinal direction, and the partition plate body 10. And an auxiliary plate 20 mounted so as to be swingable about a rotation axis 20a along the longitudinal direction.

  3A and 3B, the end surface (inner side surface) of the partition plate body 10 viewed from the accommodation space S side and the end surface (outer side surface) of the partition plate body 10 viewed from the outside, respectively. Show. FIG. 3C is a sectional view taken along line III-III in FIG.

The partition plate body 10 is mounted on the long fixed plate 60 so as to be movable in the longitudinal direction via a sliding member 30 (see FIG. 2) such as a roller.
Specifically, as shown in FIGS. 2 and 3, the partition plate body 10 includes a first joint surface 11a extending along the inner surface of the long movable plate 70 located at the closed position, and the first joint surface 11a. And a second joint surface 12 extending along the inner surface of the long fixed plate 60.

The first joining surface 11a is configured to join the inner surface of the long movable plate 70 located at the closed position between the lowermost end and a predetermined distance. That is, the length P1 of the first joining surface 11a is shorter than the inner surface width W of the long movable plate 70.
With such a configuration, when the long movable plate 70 is positioned at the closed position, a gap exists between the non-joint surface 11b and the inner surface of the long movable plate 70. The gap is formed when the long movable plate 70 is swung around the pivot shaft 70a from the closed position (solid line in FIG. 2A) to the open position (two-dot chain line in FIG. 2A). The long movable plate 70 and the partition plate main body 10 are prevented from conflicting with each other.

  The second joint surface 12 preferably extends over the entire width direction of the inner surface of the long fixed plate 60. That is, preferably, the length of the second joining surface 12 is made longer than the inner surface width of the long fixed plate 60.

The auxiliary plate 20 has at least a part of the gap between the inner surface of the long movable plate 70 and the non-joint surface 11b of the partition plate body 10 when the long movable plate 70 is located at the closed position. Thus, the partition area is substantially improved.
In the present embodiment, the auxiliary plate 20 extends along the inner surface of the long movable plate 70 from the intersection of the inner surface of the long movable plate 70 located at the closed position and the inner surface of the long fixed plate 60. The third joining surface 21 extends.
The third joint surface 21 has a length P3 that is longer than the length P1 of the first joint surface, thereby improving the substantial partition area by an area corresponding to P3-P1.
As described above, since the auxiliary plate 20 is swingable about the rotation shaft 20a with respect to the partition plate body 10, the auxiliary plate 20 swings the long movable plate 70. There is no hindrance.

Preferably, the auxiliary plate 20 includes a fourth joint surface 22 that extends along the inner surface of the long fixed plate 60 and the third joint surface 21 when the long movable plate 70 is positioned at the closed position. And an upper end surface 24 extending between the upper end portions of the fourth joint surface 22. The upper end surface 24 and the fourth joint surface 22 are connected via a curved surface 29.
By providing such a configuration, it is possible to effectively prevent the auxiliary plate 20 from coming into contact with the long fixed plate 60 when the long movable plate 70 is swung from the closed position to the open position.

The auxiliary plate 20 having such a configuration can be attached to and detached from the partition plate body 10, thereby entering between the partition plate body 10 and the auxiliary plate 20 while exhibiting the various effects. Powder can be easily removed.
That is, after performing the division work of one powder based on one prescription and then performing the work of dividing another powder based on another prescription, a part of the one powder is part of the partition plate body 10 and the auxiliary plate. If it enters between the two, the one powder may be mixed with another powder.
In the partition plate unit 1 according to the present embodiment, the partition plate body 10 and the auxiliary plate 20 that is swingable with respect to the partition plate body 10 are detachable. The powder that has entered between the auxiliary plate 20 can be easily removed.

Hereinafter, the attachment / detachment structure between the partition plate body 10 and the auxiliary plate 20 of the partition plate unit 1 according to the present embodiment will be described.
4A and 4B show an end surface (inner surface) of the auxiliary plate 20 viewed from the accommodation space S side and an end surface (outer surface) of the auxiliary plate 20 viewed from the opposite side, respectively. . FIG. 4C is a sectional view taken along line IV-IV in FIG.

  As shown in FIG. 3, the partition plate main body 10 has an engagement opening 15 that communicates between an inner side surface 13a facing the accommodation space S and an outer side surface 13b facing the opposite direction to the inner side surface 13a. Is provided.

In the present embodiment, the engagement opening 15 includes a small-diameter portion 16 whose center is the rotation shaft 20a, a large-diameter portion 17 whose center is eccentric from the center of the small-diameter portion 16, and the small-diameter portion 16 and the large-diameter portion. The communication part 18 which connects between the diameter parts 17 is included.
The communication portion 18 is narrower than the diameter of the small diameter portion 16.

On the other hand, as shown in FIG. 4, the auxiliary plate 20 has an engaging protrusion 25 on the outer side surface 23 b facing outward opposite to the inner side surface 23 a facing the accommodation space S.
The engaging protrusion 25 has a shaft portion 26 extending outward from the outer surface 23 b and a head portion 27 extending further outward from the shaft portion 26.

The shaft portion 26 has a larger diameter than the width of the communication portion 18 and a smaller diameter than the small diameter portion 16.
The head portion 27 is disposed concentrically with the shaft portion 26 and has a larger diameter than the small diameter portion 16 and a smaller diameter than the large diameter portion 17.

With such a configuration, the shaft portion 26 of the auxiliary plate 20 is inserted through the communication portion 18 in a state where the head portion 27 of the auxiliary plate 20 is inserted into the large diameter portion 17 of the partition plate body 10. The auxiliary plate 20 is moved around the center of the small diameter portion 16 by moving to the small diameter portion 16 and aligning the engaging protrusion 25 of the auxiliary plate 20 with the small diameter portion 16 of the partition plate main body 10. The main body 10 can be swingably connected.
The auxiliary plate 20 connected to the partition plate body 10 is very easily detached from the partition plate body 10 by moving the shaft portion 26 to the large diameter portion 17 via the communication portion 18. It is.

  As described above, in the partition plate unit 1 according to the present embodiment, the auxiliary plate 20 that is swingably connected to the partition plate main body 10 can be detached from the partition plate main body 10. Therefore, the residual powder that has entered between the partition plate main body 10 and the auxiliary plate 20 can be easily removed, thereby effectively preventing dispensing errors and mixing of different types of powder during the subsequent powder dividing operation.

Furthermore, the connection structure between the partition plate main body 10 and the auxiliary plate 20 employed in the present embodiment does not face the accommodation space S.
That is, in the present embodiment, both are connected by the engaging protrusion 25 formed on the outer side surface of the auxiliary plate 20 and the engaging opening 15 formed on the partition plate body 10. There is no connection structure with the partition plate body 10 on the inner surface 23a.
Therefore, unlike the conventional shaft-attached structure, the powder does not enter the connecting structure portion between the partition plate body and the auxiliary plate, and this can effectively prevent the mixture of residual powder.

When the thickness between the inner side surface 23a and the outer side surface 23b of the auxiliary plate 20 is L1, the length of the shaft portion 26 is L2, and the thickness of the head portion 27 is L3 (see FIG. 4C), Preferably, the partition plate body 10 may be formed with a recess 19a having a depth L1 in the swing region of the auxiliary plate 20 in the inner side surface 13a.
By providing such a configuration, it is possible to prevent as much as possible a step on the surface facing the accommodation space S when the partition plate body 10 and the auxiliary plate 20 are connected.

More preferably, a counterbore 19b having a depth L3 is formed in a region surrounding the engaging opening 15 in the outer side surface 13b of the partition plate body 10, and the thickness of the engaging opening 15 is L2. Can do.
By providing such a configuration, the connection body of the partition plate body 10 and the auxiliary plate 20 can be made to have a uniform thickness over substantially the entire region.

In the present embodiment, the case where the partition plate unit 1 is provided in advance in the powder supply mechanism 50 has been described as an example. However, naturally, the partition plate unit 1 according to the present invention is used as an existing powder supply mechanism. It is also possible to apply.
That is, for a medicine dispensing device having an existing powder supply mechanism, the partition plate in the existing powder supply mechanism may be removed and the partition plate unit according to the present invention may be attached.

In the present embodiment, both the partition plate body 10 and the auxiliary plate 20 are configured to define the longitudinal end of the storage space S. However, only the auxiliary plate 20 includes the storage space S. It is also possible to configure so as to define the longitudinal end.
That is, it is possible to define the longitudinal direction end of the accommodation space S only by the auxiliary plate 20, and the partition plate main body 10 can be configured to act only as a support member that supports the auxiliary plate 20.
In such an aspect, the partition plate main body 10 can have various forms as long as the partition plate body 10 is movable in the longitudinal direction and can support the auxiliary plate 20.

Embodiment 2. FIG.
Hereinafter, an embodiment of an end plate unit according to the present invention will be described with reference to the accompanying drawings.
FIG. 5 is a partial plan view of the powder supply mechanism 150 to which the end plate unit according to the present embodiment is applied. 6 is a cross-sectional view taken along line VI-VI in FIG.
In the present embodiment, the same or corresponding members as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

The powder supply mechanism 150 has substantially the same configuration as the powder supply mechanism 50 in the first embodiment.
That is, the powder supply mechanism 150 includes a long fixed plate 60 and a long movable plate 70 extending in the same direction as the longitudinal direction of the long fixed plate 60, and swings around a pivot shaft along the longitudinal direction. A long movable plate 70 that can be moved, an end plate 180 that is located near one end of the long fixed plate 50 and a corresponding one end of the long movable plate, and is slidable in the longitudinal direction. And a partition plate unit (not shown).

The end plate 180 is located at one end in the longitudinal direction of the accommodation space S formed by the long movable plate 70 (solid line in FIG. 6) and the long fixed plate 60 located at the closed position.
More specifically, the end plate 180 is disposed such that the inner end surface 181 facing the accommodation space S faces the end surface 75 at one end portion in the longitudinal direction of the long movable plate 70. That is, the long movable plate 70 can take the closed position and the open position in a state where the end surface 75 at one end in the longitudinal direction faces the inner end surface 181 of the end plate 180.
