Description

The present invention relates to a drug supply device and a drug packaging device.

As disclosed in Japanese Patent Application Laid-Open No. 2004-268991 (Patent Document 1), a passage for guiding the drug is provided inside the drug supply device. A passage is generally configured by connecting a plurality of passage-forming members. When connecting a plurality of passage forming members, it is necessary to reduce or eliminate the gap formed between the plurality of passage forming members.

When a gap larger than the drug is formed, the drug tends to leak out of the passage through the gap, and it is often difficult to supply the correct amount of the drug. However, the work of strictly adjusting the gap between the plurality of passage forming members (positioning work of the passage forming member) requires time and labor, and the worker assembling the drug supply device and the plurality of passage forming members are disassembled. It can be a burden to the user who reassembles and uses it after cleaning it.

The standing wall portions 52CA, 52CS and 52CB have upper end portions 52CAT, 52CST and 52CBT, respectively. The upper end portions 52CAT, 52CST, and 52CBT are portions of the standing wall portions 52CA, 52CS, and 52CB located on the upstream side. The upper end portions 52CAT, 52CST, and 52CBT form the upper end portion of the tubular portion 52C (the upper end portion having a shape extending in a substantially U shape in a plan view).

The opening located on the upstream side of the passage 52CH is defined by the standing wall portions 52CA, 52CS, 52CB and the upper panel 52E. The opening located on the most upstream side of the passage 52CH is defined by the upper end portion (upper end portion 52CAT, 52CST, 52CBT) of the tubular portion 52C (standing wall portion 52CA, 52CS, 52CB) and the outer edge 52EC of the upper panel 52E.

The protruding portion 52CAU is formed so that a part of the upper end portion 52CAT protrudes toward the side where the connecting member 53 is arranged. As described above, the passage forming member 51 (FIGS. 5 and 7) is moved horizontally together with the connecting member 53 as shown by the arrow AR50 and is arranged above the passage forming member 52.

The protrusion 52CAU is in this horizontal direction (direction indicated by arrow AR50), that is, a direction parallel to the direction in which the passage forming member 51 and the connecting member 53 are moved (relatively moved) upward of the passage forming member 52. It extends to. Due to the presence of the protrusion 52 CAU, a gap S is formed between the passage forming member 52 and the connecting member 53. When the projecting portion 52CAU is provided on the upper end portion 52CAT, the passage is formed as compared with the case where the protruding portion 52CAU is not provided on the upper end portion 52CAT and the upper end portion 52CAT has a flat surface shape. The contact area between the member 52 and the connecting member 53 becomes smaller. The projecting portion 52CAU constitutes a "friction reducing portion" that reduces the friction generated between the passage forming member 52 and the connecting member 53 when they move relative to each other in the horizontal direction.

It extends to. Due to the presence of the protrusion 52CBU, a gap S is formed between the passage forming member 52 and the connecting member 53. When the protruding portion 52CBU is provided on the upper end portion 52CBT, a passage is formed as compared with the case where the protruding portion 52CBU is not provided on the upper end portion 52CBT and the upper end portion 52CBT has a flat surface shape. The contact area between the member 52 and the connecting member 53 becomes smaller. The protruding portion 52CBU constitutes a "friction reducing portion" that reduces the friction generated between the passage forming member 52 and the connecting member 53 when they move relative to each other in the horizontal direction.

With reference to FIG. 9, the protrusion height H from the upper end portions 52CAT and 52CBT of the protrusions 52CAU and 52CBU is, for example, 0.3 mm to 0.5 mm. If the dimension in the direction perpendicular to the extending direction of the protruding portions 52CAU and 52CBU is defined as "width", the width W of the protruding portions 52CAU and 52CBU is, for example, 0.6 mm to 1.0 mm. The cross-sectional shape of the protruding portions 52CAU and 52CBU can be any shape such as a semicircular shape, a trapezoidal shape, a triangular shape, and a square shape.

As described above, the upper end portion (upper end portion 52CAT, 52CST, 52CBT) of the tubular portion 52C of the passage forming member 52 is arranged so as to be adjacent to the lower end portion of the connecting member 53. The passage forming member 52 allows the drug that has passed through the passage 51H of the passage forming member 51 and the passage 53H (third passage) of the connecting member 53 to pass through the passage 52CH and further downward (packaging portion 60).

The connecting member 53 is detachably attached to the passage forming member 51 as shown by the arrow AR53. The protrusion 51RT is arranged inside the opening 53RH provided in the connecting member 53, and the protrusion 51LT is arranged inside the opening 53LH provided in the connecting member 53. A gap is formed in the vertical direction between the inner peripheral edge forming the opening 53RH of the connecting member 53 (peripheral wall 53R) and the protrusion 51RT. A gap is formed in the vertical direction between the inner peripheral edge forming the opening 53LH of the connecting member 53 (peripheral wall 53L) and the protrusion 51LT. With this configuration, the connecting member 53 can move up and down (relatively move in the vertical direction) with respect to the passage forming member 51 in a state where the connecting member 53 is attached to the passage forming member 51.

Details will be described later with reference to FIG. 12, but in a state where the passage forming member 51, the passage forming member 52, and the connecting member 53 are arranged in the lower housing 12 of the housing 10, the connecting member 53 forms the passage. It is in contact with the passage forming member 52 in a state of being urged toward the member 52 (in the direction indicated by the arrow DR). In the present embodiment, the connecting member 53 is attached to the passage forming member 51 (first passage forming member), and the connecting member 53 is the passage forming member 52 (second passage forming member) due to the action of the weight of the connecting member 53. Is in contact with. The weight of the connecting member 53 includes the weights of the weights 53BW and 53CW, and the weights 53BW and 53CW increase the urging force (contact pressure) of the connecting member 53 with respect to the passage forming member 52.

Here, the position and inclination of the inclined portion 53B provided on the connecting member 53 are specified as follows. As shown in FIGS. 10 and 11, the connecting member 53 configured to be horizontally movable with respect to the passage forming member 52 (the other member) is horizontally movable from the passage forming member 52 (the other member).

(Action of drug packaging device 100)
In the drug packaging device 100, regular maintenance work is performed. When performing maintenance work, each passage forming member is often taken out from the lower housing 12, and chemicals and powders of chemicals adhering to the passage of each passage forming member are removed by cleaning. After that, each passage forming member is returned to a predetermined position in the lower housing 12.

Since the passage forming members 51 and 52 are relatively movable, the above-mentioned work can be easily performed. Hereinafter, the operation and effect of the drug packaging device 100 will be described based on the work of arranging the passage forming member 51 in the lower housing 12 (FIGS. 1 to 3). 10 to 12 are side views showing the first to third stages of the work of arranging the passage forming member 51 in the lower housing 12 (FIGS. 1 to 3), respectively. In the state shown in FIGS. 10 to 12, the passage forming member 52 and the like are arranged in advance at predetermined positions in the lower housing 12.

(1st stage)
As shown in FIG. 10, in the first stage, the passage forming member 51 and the connecting member 53 are arranged at positions away from the passage forming member 52. In the present embodiment, the passage forming member 51 can move relative to the passage forming member 52 in the horizontal direction in a state where the connecting member 53 is attached to the passage forming member 51.

The protrusion 51LT provided on the peripheral wall 51L of the passage forming member 51 is located at the upper end of the opening 53LH provided on the peripheral wall 53L of the connecting member 53. Although not shown in FIG. 10, the same applies to the protrusion 51RT and the opening 53RH. The connecting member 53 is formed in a state of being suspended from the passage forming member 51.

(Second stage)
With reference to FIG. 11, when the passage forming member 51 advances horizontally along the direction indicated by the arrow AR50, the inclined portion 53B of the connecting member 53 comes into contact with the upper end portion 52CST of the passage forming member 52 (second stage). .. As described above, the inclined portion 53B is directed in the direction opposite to the urging direction (direction indicated by arrow DR shown in FIG. 12) toward the front (left side of the paper in FIG. 12) in the approaching direction (direction indicated by arrow AR50) (here). Then it is tilted toward the top).

The connecting member 53 is inclined so as to ride on the upper end portion 52CST of the passage forming member 52. Due to the inclined shape of the inclined portion 53B, the connecting member 53 can ride on the passage forming member 52 with almost no resistance. When the passage forming member 51 further advances in the horizontal direction along the direction indicated by the arrow AR50, the lower surface of the connecting member 53 is arranged on the upper end portions 52CAT and 52CBT (see FIG. 8) of the passage forming member 52. The connecting member 53 is urged to the passage forming member 52 by the action of its own weight.

In the present embodiment, protruding portions 52CAU and 52CBU (friction reducing portions) are formed on the upper end portions 52CAT and 52CBT. Due to the presence of the protrusions 52CAU and 52CBU, the contact area between the lower surface of the connecting member 53 and the passage forming member 52 is reduced. Even if the passage forming member 51 moves in the direction indicated by the arrow AR50 (or the opposite direction), the passage forming member 52 and the connecting member 53 rarely rub against each other, and the passage forming member 52 and the connecting member 53 rub against each other. There is almost no decrease in wear debris. Further, when the passage forming member 51 is moved in the direction indicated by the arrow AR50 (or the opposite direction), the generation of abnormal noise due to friction is effectively suppressed.

The protruding portions 52CAU and 52CBU have a shape extending long along the direction indicated by the arrow AR50, but the extending direction of the protruding portions 52CAU and 52CBU does not have to be parallel to the direction indicated by the arrow AR50. .. The protrusions 52CAU and 52CBU may have a discontinuous shape. As the friction reducing portion that exerts such an effect, a special surface treatment capable of realizing a low surface friction coefficient is carried out in place of the configuration of the protruding portions 52CAU and 52CBU, or in addition to the configuration of the protruding portions 52CAU and 52CBU. It may be configured by. The friction reducing portion may be configured by arranging a plurality of rotating rollers along the direction indicated by the arrow AR50 at or near the upper end portions 52CAT and 52CBT.

When the passage forming member 52 and the connecting member 53 move relative to each other in the horizontal direction, such as a protruding portion such as a protruding portion 52CAU or 52CBU, a special surface treatment capable of achieving a low surface friction coefficient, or a plurality of rotating rollers.

May be.

(Third stage)
With reference to FIG. 12, when the passage forming member 51 advances horizontally along the direction indicated by the arrow AR50, the opening located on the most downstream side (lower side) of the passage 53H (FIG. 6) and the passage The opening located on the most upstream side (upper side) of 52CH (FIG. 7) coincides with the opening (third stage).

The protrusion 51LT provided on the peripheral wall 51L of the passage forming member 51 is located at a position away from the upper end of the opening 53LH provided on the peripheral wall 53L of the connecting member 53. Although not shown in FIG. 12, the same applies to the protrusion 51RT and the opening 53RH. The connecting member 53 does not form a state of being suspended from the passage forming member 51, but is placed on the upper end portions 52CAT, 52CBT (protruding portions 52CAU, 52CBU) of the passage forming member 52. Is forming.

The connecting member 53 is in contact with the passage forming member 52 in a state of being urged toward the passage forming member 52 (in the direction indicated by the arrow DR). In the present embodiment, the connecting member 53 is attached to the passage forming member 51 (first passage forming member), and the connecting member 53 is the passage forming member 52 (second passage forming member) due to the action of the weight of the connecting member 53. Is in contact with. The weight of the connecting member 53 includes the weight of the weights 53BW and 53CW, and the weights 53BW and 53CW increase the urging force (contact pressure) of the connecting member 53 with respect to the passage forming member 52 with a simple configuration. I have realized that. In addition to the action of the weight of the connecting member 53, the elastic force of a coil spring, a leaf spring, or the like, or the magnetic force of a magnet may be used to increase the urging force (contact pressure) of the connecting member 53 with respect to the passage forming member 52. The weights 53BW and 53CW may also be provided on the connecting member 53 as needed.

(Effect of drug packaging device 100)
As described at the beginning, when connecting a plurality of passage forming members, it is necessary to reduce or eliminate the gap formed between the plurality of passage forming members. When a gap larger than the drug is formed, the drug tends to leak out of the passage through the gap, and it is often difficult to supply the correct amount of the drug. The work of strictly adjusting the gap (positioning work of the passage forming member) requires time and labor, and is used by a worker who assembles a drug supply device or after disassembling and cleaning a plurality of passage forming members. It can be a burden on the user.

On the other hand, according to the drug packaging device 100 of the present embodiment, the passage forming member 51 and the passage forming member 52 are arranged in the lower housing 12 in a state where the passage forming member 51 and the passage forming member 52 are arranged in the lower housing 12. Are separated from each other with a vertical interval. The passage 53H (third passage) of the connecting member 53 connects the passage 51H (first passage) of the passage forming member 51 and the passage 52CH (second passage) of the passage forming member 52. The drug supplied from the drug addition device 40 (FIGS. 2 and 3) can be supplied to the packaging unit 60 through the drug supply device 50 (FIGS. 3 and 4).

The connecting member 53 is attached to the passage forming member 51 so as to be vertically movable, and the connecting member 53 is in contact with the passage forming member 52 in a state of being urged toward the passage forming member 52. A gap is rarely formed between the passages 51H and 53H, and a gap is hardly formed between the passages 53H and 52H. Even if the vertical spacing (gap) between the passage forming members 51 and 52 is not strictly adjusted, this gap is closed by the connecting member 53, and it is possible to prevent the drug from leaking from the gap. ..

Due to the presence of the protrusions 52CAU and 52CBU, the contact area between the lower surface of the connecting member 53 and the passage forming member 52 is reduced. Even if the passage forming member 52 moves in the direction indicated by the arrow AR 52 (or the opposite direction), the passage forming member 52 and the connecting member 53 rarely rub against each other, and the passage forming member 52 and the connecting member 53 rub against each other. There is almost no decrease in wear debris. Further, when the passage forming member 52 is moved in the direction indicated by the arrow AR 52 (or the opposite direction), the generation of abnormal noise due to friction is effectively suppressed.

The protrusions 52CAU and 52CBU have a shape extending long along the direction indicated by the arrow AR52, but the protrusions 52CAU and 52CBU may have a discontinuous shape. As the friction reducing portion that exerts such an effect, a special surface treatment capable of realizing a low surface friction coefficient is carried out in place of the configuration of the protruding portions 52CAU and 52CBU, or in addition to the configuration of the protruding portions 52CAU and 52CBU. It may be configured by.

The protrusion 51LT provided on the peripheral wall 51L of the passage forming member 51 is located at a position away from the upper end of the opening 53LH provided on the peripheral wall 53L of the connecting member 53. Although not shown in FIG. 15, the same applies to the protrusion 51RT and the opening 53RH. The connecting member 53 does not form a state of being suspended from the passage forming member 51, but is placed on the upper end portions 52CAT, 52CBT (protruding portions 52CAU, 52CBU) of the passage forming member 52. Is forming.

The connecting member 53 is in contact with the passage forming member 52 in a state of being urged toward the passage forming member 52 (in the direction indicated by the arrow DR).

Not limited to such a configuration, in a state where the connecting member is attached to any one of the first passage forming member and the second passage forming member, the one member is horizontally relative to the other member. It may be virtually impossible to move. For example, the idea disclosed in the above embodiment can be applied to a passage forming member that is not supposed to be replaced or cleaned in the drug packaging device 100. Even if the gap (gap) between the passage forming members adjacent to each other in the vertical direction is not strictly adjusted, the gap can be closed by the connecting member, and the drug can be prevented from leaking from the gap. Such a form can be effectively implemented by, for example, an operator who assembles a drug supply device.

[Modification 3]
In the above-described embodiment, the connecting member 53 is provided with inclined portions 53B and 53C. The connecting member 53 may be provided with either one of the inclined portions 53B and 53C.

[Modification example 4]
In the above-described embodiment, the connecting member 53 is provided with the inclined portion 53B. The effect of the inclined portion 53B can be obtained even if the passage forming member 52 (the other member of the first passage forming member and the second passage forming member) is provided with the inclined portion. For example, instead of providing the inclined portion 53B on the connecting member 53, or in addition to providing the inclined portion 53B on the connecting member 53, an inclined portion may be provided on the upper end portion 52CST of the passage forming member 52.

When an inclined portion is provided on the upper end portion 52CST of the passage forming member 52, the position and inclination of the inclined portion are specified as follows. As shown in FIGS. 10 and 11, the connecting member 53 configured to be horizontally movable with respect to the passage forming member 52 (the other member) is horizontally movable from the passage forming member 52 (the other member). The direction of approaching the passage forming member 52 (the other member) from a distant position is defined as the "approaching direction" (the direction indicated by the arrow AR50). Here, since the connecting member 53 approaches the passage forming member 52 as shown by the arrow AR50, the passage forming member 52 relatively approaches the connecting member 53 in the direction opposite to the direction indicated by the arrow AR50. Therefore, the upper end portion 52CST of the passage forming member 52 is located in front of the passage forming member 52 (the other member) in the direction opposite to the approaching direction.

In a state where the connecting member 53 is urged toward the passage forming member 52 (the other member) (the state shown in FIG. 12), the connecting member 53 is urged toward the passage forming member 52 (the other member). The direction is defined as the urging direction (direction indicated by the arrow DR). The inclined portion provided at the upper end portion 52CST of the passage forming member 52 is directed toward the front (left side of the paper in FIG. 12) in the above-mentioned approach direction (here, the direction indicated by the arrow AR50), and is shown in the urging direction (indicated by the arrow DR). It is configured to incline in the direction opposite to the direction (see FIG. 10). With this configuration, the same effect as that of the inclined portion 53B can be obtained.

[Modification 5]
In the above-described embodiment, the connecting member 53 is provided with the inclined portion 53C. The effect of the inclined portion 53C can be obtained even if the passage forming member 52 (the other member of the first passage forming member and the second passage forming member) is provided with the inclined portion. For example, instead of providing the inclined portion 53C on the connecting member 53, or in addition to providing the inclined portion 53C on the connecting member 53, an inclined portion may be provided on the upper end portion 52J of the passage forming member 52.

When an inclined portion is provided at the upper end portion 52J of the passage forming member 52, the position and inclination of the inclined portion are specified as follows. As shown in FIGS. 13 and 14, the connecting member 53 configured to be horizontally movable with respect to the passage forming member 52 (the other member) is horizontally movable from the passage forming member 52 (the other member). The direction of approaching the passage forming member 52 (the other member) from a distant position is defined as the "approaching direction". Here, since the passage forming member 52 approaches the connecting member 53 as shown by the arrow AR 52, the connecting member 53 relatively approaches the passage forming member 52 in the direction opposite to the direction indicated by the arrow AR 52. Therefore, the direction opposite to the direction indicated by the arrow AR52 corresponds to the approaching direction. The upper end portion 52J of the passage forming member 52 is located forward in the direction opposite to the approaching direction of the passage forming member 52 (the other member) (that is, the front in the arrow AR 52).

In a state where the connecting member 53 is urged toward the passage forming member 52 (the other member) (the state shown in FIG. 15), the connecting member 53 is urged toward the passage forming member 52 (the other member). The direction is defined as the urging direction (direction indicated by the arrow DR). The inclined portion provided at the upper end portion 52J of the passage forming member 52 is directed toward the front (right side of the paper in FIG. 15) in the above-mentioned approaching direction (here, the direction opposite to the direction indicated by the arrow AR52). It is configured to incline in the direction opposite to the direction indicated by the arrow DR (see FIG. 13). With this configuration, the same effect as that of the inclined portion 53C can be obtained.

[Modification 6]
The idea disclosed in the above-described embodiment is applied to a configuration in which the passage forming members 51 and 52 are arranged with a gap, and the connecting member 53 is arranged so as to connect them. The idea disclosed in the above embodiment may be applied, for example (see FIG. 4), between the lower body 22B of the drug storage / delivery device 20 (passage forming member 22) and the upper end 23A of the passage forming member 23. Alternatively, it may be applied between the lower end portion 23B of the passage forming member 23 and the upper end portion 52AT of the passage forming member 52. The idea disclosed in the above-described embodiment may be applied between the lower body 32B of the drug storage / delivery device 30 (passage forming member 32) and the upper end 33A of the passage forming member 33, or the passage forming member 33. It may be applied between the lower end portion 33B of the above and the upper end portion 52BT of the passage forming member 52.
