Side plates 8 are arranged on the left and right side surfaces of the housing 2.

FIG. 2 shows a state in which the door 6a of the drug supply device 101 is opened. By opening the door 6a, the drum 20 can be seen through the opening 3. FIG. 3 shows a state in which the doors 6a and 6b, the front plate 4, and the side plate 8 of the housing 2 are removed. The ceiling portion 5 is supported by several pillars 11 extending in the vertical direction. At least four of the plurality of pillars 11 are arranged so as to support the four corners of the ceiling portion 5. Two drums 20 are arranged under the ceiling portion 5. Each drum 20 is individually rotatably installed. Here, an example in which one drug supply device 101 includes two drums 20 is shown, but the number of drums included in one drug supply device may be other than two. The drug supply device may have one drum or three or more drums.

The structure of the drum 20 is schematically shown in FIG. One drum 20 includes a combination of four divided bodies 30 and has a cylindrical shape. The drum 20 is supported so that it can rotate around a center line 81 extending in the vertical direction. Here, it is assumed that one drum 20 is a combination of a total of four divided bodies at 90 ° intervals, but this is just an example, and one drum may be a combination of n divided bodies. n is an integer of 2 or more. The central angle per divided body can change depending on the value of n. The central angle per divided body may be, for example, an angle obtained by equally dividing 360 ° by n. The drum includes n divisions, and may further include a mechanism for fastening these divisions to each other or a mechanism for holding these divisions.

FIG. 5 shows a place where one divided body 30 is taken out. The divided body 30 includes an upper portion 34 and a lower portion 35. A plurality of drug supply units 31 are arranged between the upper portion 34 and the lower portion 35. Each of the drug supply units 31 is supported by the support unit 32. Each of the plurality of drug supply units 31 contains a plurality of drugs. That is, for example, when the drug is a tablet, a plurality of tablets of the drug are contained in one drug supply unit 31. When paying attention to any one of the plurality of drug supply units 31, the drug supply unit 31 basically contains only the same type of drug. When paying attention to a plurality of drug supply units 31, in principle, different drug supply units 31 contain different types of drugs. However, for drugs that are frequently used, the same type of drug may be accommodated across a plurality of drug supply units 31. Each of the plurality of drug supply units 31 can supply the drug contained therein. The drug supply unit 31 may be a cassette capable of accommodating the drug. The drug supply unit 31 may be provided with a handle for the user to hold when attaching / detaching. FIG. 6 shows the views of the divided body 30 from different sides. The divided body 30 has an inner peripheral surface 39. The inner peripheral surface 39 may be a curved surface. A radial passage 37 is opened on the inner peripheral surface 39 so as to correspond to each of the drug supply portions 31. The radial passage 37 extends so as to include a component in the radial direction R. Each inner surface of the radial passage 37 is provided with an inclined surface 38 that is inclined with respect to the axial direction Z. The split body 30 has two sides 40,43. The split body 30 includes two shaft support portions 42 at the ends of the side surface 40. The two shaft branches 42 are arranged so as to be arranged in the vertical direction along a common shaft A.

Focusing on the drum 20 on the left side when facing the front of the drug supply device 101, a cross-sectional view of the vicinity of the drum 20 is shown in FIG. In FIG. 7, the door 6a is not shown.

8 and 9 show a state in which the door 6a of the drug supply device 101 is opened and one divided body 30 is pulled out from the opening 3. The axial passage 51 is a passage through which the medicine discharged from the radial passage 37 (see FIG. 6) falls. As shown in FIGS. 7 and 9, the axial passages 51 are arranged in an annular shape inside the drum 20. The axial passage 51 extends in the front-back direction of the paper in FIGS. 7 and 9. In FIG. 9, the door 6a is not shown. The divided body 30 is rotatably supported around the shaft A by the shaft support portion 42. As a result, the divided body 30 can rotate toward the outside of the drum 20. When the user cleans, repairs, inspects, or the like inside the drum 20, the divided body 30 can be pulled out toward the front in this way. In FIG. 8, by pulling out one divided body 30 toward the front, the axial passage 51 inside the drum 20 can be seen. However, this is just an example, and the divided body 30 does not always rotate in such a manner.

FIG. 10 shows a partial cross-sectional view of the vicinity of the axial passage 51 when viewed from the side. The right side in FIG. 10 corresponds to the inner peripheral side of the drum 20, and the left side corresponds to the outer peripheral side of the drum 20. The end on the inner peripheral side of the drug supply unit 31 is connected to the radial passage 37. The radial passage 37 is connected to the axial passage 51. The inner peripheral surface 39 faces the axial passage 51. A view of the drum 20 from above is shown in FIG.

The drug discharged from the drug supply section 31 passes through the passage section. The passage portion includes a radial passage 37 and an axial passage 51. The term "passage" includes not only the space through which the drug passes but also the peripheral members used to define such a space. The passage portion includes a collided member 52 as a member with which the drug collides. The collided member is a member that can be elastically deformed. The collided member 52 is arranged so as to face the inner peripheral surface 39. A support column 50 is arranged near the center of the drum 20. A back surface portion 53 is arranged around the support column 50. The collided member 52 is arranged in a state of being slightly separated from the back surface portion 53. A gap 57 is provided between the collided member 52 and the back surface portion 53.

The drug supply device 101 includes at least one drug supply unit 31 that supplies the drug, and a passage unit through which the drug supplied from the drug supply unit 31 passes. The passage portion faces the collided member 52, which is a member with which the drug collides and is elastically deformable, the holding portions 54a, 54b for holding the collided member 52, and the side opposite to the side on which the drug collides. The back surface portion 53 is provided so as to face the collision-affected member 52 with the gap 57 so as to limit the amount of elastic deformation of the collision-affected member 52.

The back surface portion 53 may be a wall made of resin. The back surface portion 53 may be integrally formed with the support column 50. In the vicinity of the center of the drum 20, the holding portions 54a and the holding portions 54b are alternately and radially arranged so as to surround the support column 50. As shown in FIG. 11, the holding portions 54a and 54b may be formed as protrusions protruding in the radial direction from the support column 50. The holding portions 54a and 54b each have a groove 55. The groove 55 extends in the vertical direction. That is, the groove 55 extends in the front-back direction of the paper surface in FIG. The collided member 52 also extends in the front-back direction of the paper surface in FIG. The collided member 52 is a strip-shaped member having a longitudinal direction in the vertical direction. As shown in FIG. 11, both ends of the collided member 52 in the width direction are housed in the groove 55. The holding portions 54a and 54b are provided with protrusions 56 in the vicinity of the groove 55. The protrusion 56 may be in contact with the collided member 52 from the inner peripheral side of the drum 20.

FIG. 12 shows a partial perspective view in a state where the collided member 52 is held by the holding portions 54a and 54b. The holding portions 54a and 54b extend in the vertical direction, respectively, and the band-shaped collided member 52 extends in the vertical direction so as to be sandwiched between them. Since the holding portions 54a and 54b are formed by connecting a plurality of resin molded parts and lengthening them in the vertical direction, the boundary between the resin molded parts is visible in FIG. In FIG. 12, two strip-shaped collision-affected members 52 were visible, and FIG. 13 shows a state in which the collision-affected member 52 on the left side in the figure is removed. In the portion where the collision member 52 is removed, the back surface portion 53 is exposed between the holding portions 54a and 54b. In FIG. 13, the groove 55 is visible at the base of the holding portion 54a. Although it is hidden and invisible in FIG. 13, there is also a groove 55 at the base of the holding portion 54b. Grooves 55 are provided on both sides of the holding portion 54a. Grooves 55 are also provided on both sides of the holding portion 54b. At some points in the middle of each groove 55, protrusions 56 are arranged so as to narrow the width of the groove 55. The tip of the protrusion 56 protrudes toward the outer peripheral side of the drum 20 as compared with the back surface portion 53.

Since there is a gap 57 behind the collided member 52, when the chemical collides with the collided member 52 or when the collided member 52 is pushed as part of the cleaning work, the collided member 52 opens the gap 57. Only the amount of can be elastically deformed freely. However, since the back surface portion 53 is further behind, the collided member 52 comes into contact with the back surface portion 53 after being deformed by the amount of the gap 57, and cannot be elastically deformed any more. In this way, the back surface portion 53 limits the amount of elastic deformation of the collided member 52 toward the side opposite to the side on which the drug collides. It is preferable that the back surface portion 53 is not easily deformed. The back surface portion 53 is preferably a member having a higher rigidity than the collided member 52. The back surface portion 53 may be made of, for example, a resin.

When the collided member 52 is attached to the holding portions 54a and 54b, it can be inserted from the upper end as shown by an arrow in FIG. In FIG. 14, the upper end of the drum 20 is partially displayed. The grooves 55 provided in the holding portions 54a and 54b extend in the vertical direction and are opened in this way at the upper end of the drum 20, so that the collided member 52, which is a strip-shaped plate material, is inserted. be able to. However, the structure shown in FIG. 14 is schematically shown for convenience of explanation, and the detailed structure is not always the same. In FIG. 14, the protrusion 56 is not shown.

(Action / effect)
In the present embodiment, since the impacted member 52 that can be elastically deformed is provided in the passage portion, the degree of splashing of the drug can be reduced. For example, as shown in FIG. 15, when the drug M discharged from the drug supply unit 31 and rolled down through the radial passage 37 collides with the collided member 52 exposed in the axial passage 51, conventionally Where it would have bounced large as shown by the dotted line, it can bounce only small as shown by the solid line. Further, the back surface portion 53 is arranged so as to face the collided member 52 via the gap 57 so as to limit the amount of elastic deformation of the collided member 52 toward the side opposite to the side on which the drug collides. Therefore, it is possible to elastically deform the collided member 52 and press it against the back surface portion at the time of cleaning. If cleaning is performed in such a state of being pressed against the back surface portion, it is easy to apply a force to the collided member, so that cleaning becomes easy.

As shown in the present embodiment, the collided member 52 is preferably a plate-shaped member. This is because if the collided member 52 has a plate shape, the incoming chemicals can be reliably received over a wide range to some extent. Further, if the collided member is a plate material, it can be arranged with a small floor area when it is arranged so as to extend in the vertical direction. If the collided member is a plate material, it can be easily elastically deformed and pressed against the back surface during cleaning.

As shown in the present embodiment, the holding portions 54a and 54b have a groove 55 and hold the collided member 52 by receiving at least a part of the outer periphery of the collided member 52 into the groove 55. Is preferable. If the collided member is held by using the groove in this way, the collided member can be easily held with a small number of parts.

As shown in the present embodiment, it is preferable that the holding portions 54a and 54b hold the collided member 52 by receiving at least a part of both ends of the collided member 52 in the left-right direction into the groove 55. .. By adopting this configuration, it is possible to stably hold the collided member extending in the vertical direction.

As shown in the present embodiment, the holding portions 54a and 54b preferably hold the collided member 52 with play. Since there is play in the holding state of the collided member 52 in this way, when the drug collides with the collided member 52, the collided member 52 can be displaced with respect to the holding portion to some extent. It can absorb the impact of drug collision and reduce the rebound of drug. However, having play is preferable but not essential. A certain effect can be obtained even with a holding method in which there is little or no play. For example, it is conceivable to hold the widthwise end of the collided member by screwing.

As shown in the present embodiment, the "at least one drug supply section 31" includes a plurality of drug supply sections 31 arranged side by side in the vertical direction, and the length of the collided member 52 in the vertical direction is large. It is preferable that the collided member 52 is integrally formed so as to correspond to the length of the plurality of drug supply units 31 arranged in the vertical direction. If the collided member 52 is integrally formed over a sufficient length in this way, the surface on which the drug collides in the passage portion can have a seamless structure, so that the drug can be dropped smoothly. Can be done. Further, since the collided member 52 is integrated and has no seam, the passage portion can be easily cleaned.

As shown in the present embodiment, the holding portions 54a and 54b preferably hold at least a part of the outer circumference of the collided member 52. By holding in this way regardless of the presence or absence of play, the collided member can be held satisfactorily. It is preferable that the member to be collided is held near the outer periphery, and the central portion of the member to be collided is in a freely deformable state. In this way, the impact when the drug collides is easily absorbed by the collided member.

It is preferable that the collided member 52 is detachable from the holding portions 54a and 54b. FIG. 14 shows how the collided member 52, which is a strip-shaped plate material, is inserted into the groove 55 of the holding portions 54a and 54b, but it can also be pulled out. By making it removable in this way, when the collided member 52 is soiled or damaged, it can be easily replaced.

The collided member 52 is preferably made of resin. The collided member 52 is preferably made of an ultra-high molecular weight polyethylene resin. By adopting this configuration, it is possible to realize a collided member having excellent wear resistance and chemical resistance. In addition, it is possible to realize a structure in which the drug does not easily bounce off.

Up to this point, a drug supply device including a drum in which a plurality of drug supply units are arranged in a cylindrical shape has been described as an example, but the drug supply device is not limited to such a structure. For example, the present invention can be applied to a drug supply device in which a plurality of drug supply units are arranged in parallel. The plurality of drug supply units may be arranged along a certain plane, for example. A plurality of drug supply units may be arranged along a plurality of planes.

In the examples described so far, the collided member is provided in a direction in which the normal vector does not include an upward component, but this is only an example and is not limited to such a member. The collided member may be provided so that, for example, the normal vector is oriented so as to include an upward component. For example, the collided member may be provided in a posture in which the surface of the collided member is horizontal. The collided member may be provided so as to be inclined with respect to the horizontal plane. The present invention can be applied regardless of the posture in which the collided member is provided.

As described in the first embodiment, "at least one", the number of drug supply units may be one or more. For example, the present invention is applied to a drug supply device having one drug supply unit. It is possible.

It should be noted that the above-described embodiment disclosed this time is an example in all respects and is not restrictive. The scope of the present invention is indicated by the scope of claims and includes all modifications within the meaning and scope equivalent to the scope of claims.
