  FIG. 6 is a cross-sectional view of the liquid medicine supply apparatus 1 along the line VI-VI shown in FIG. FIG. 7 is a cross-sectional view of the liquid medicine supply device 1 along the line VII-VII shown in FIG. As clearly shown in FIGS. 6 and 7, the liquid medicine supply device 1 of the present embodiment needs to be stored in a cold place on the liquid medicine bottle holder 32 in the lower space 12 after opening. A cooling case 90 is provided as a casing for appropriately storing the liquid medicine 5 to be stored inside the housing 6. The cooling case 90 is formed in a substantially rectangular parallelepiped shape, and is placed and fixed on the upper surface of the liquid medicine bottle holding body 32 in a state where the rectangular parallelepiped shape stands up.

  The cooling case 90 surrounds an internal space 91 that is a partial space inside the housing 6 and seals the internal space 91. An openable / closable door 90a is disposed on the surface of the cooling case 90 on the side away from the drum axis L1. By opening the door 90 a, the liquid medicine bottle 23 can be accommodated in the internal space 91 of the cooling case 90, or the liquid medicine bottle 23 can be taken out from the internal space 91. By closing the door 90a, the cooling case 90 forms an airtight structure, and the internal space 91 is formed as a sealed space. A heat insulating material 92 is provided on the entire wall surface, ceiling surface, and floor surface of the cooling case 90. The heat insulating material 92 suppresses heat transfer from the outside of the cooling case 90 to the internal space 91, whereby the internal space 91 is maintained at a low temperature.

  The internal space 91 of the cooling case 90 is formed so as to have a shape necessary for arranging the liquid medicine bottle 23. The cooling case 90 has a minimum volume that can accommodate the liquid medicine bottle 23. The pump 24 is disposed outside the cooling case 90. In the upper part of the door 90 a of the cooling case 90, a notch (not shown) is formed for allowing a tube forming a passage for the liquid medicine 5 flowing from the liquid medicine bottle 23 toward the supply nozzle 36 to pass therethrough.

  A cooling unit 93 that cools the inside of the cooling case 90 is disposed on the surface of the cooling case 90 on the side close to the drum axis L1, that is, on the back surface facing the door 90a. Although any device having a function of cooling the internal space 91 can be used as the cooling unit 93, for example, a Peltier element advantageous for downsizing may be used for the cooling unit 93. When the cooling unit 93 includes a heat generating unit 94 that generates heat, such as when the cooling unit 93 is a Peltier element, or when the cooling unit 93 generates Joule heat, the heat generating unit 94 is provided on the back side of the cooling case 90. It is arranged on the outer side, that is, on the side close to the drum axis L1 with respect to the cooling case 90. The heat generating portion 94 is disposed inside the duct 95 as shown in FIG.

  The duct 95 includes an intake duct 96 that extends in the vertical direction, an exhaust duct 98 that extends in the vertical direction adjacent to the intake duct 96, and a communication portion 97 that connects the intake duct 96 and the exhaust duct 98. The duct 95 is disposed through the bottom plate 9 of the housing 6 and communicates the inside and the outside of the housing 6. The inside of the duct 95 does not communicate with the lower space 12 in the housing 6. Air flows into the intake duct 96 via the intake port 96a. The intake port 96 a is formed on the lower side of the housing 6 and opens to the outside of the housing 6. Air flows out from the exhaust duct 98 via the exhaust port 98a. The exhaust port 98 a is formed on the lower side of the housing 6 and opens to the outside of the housing 6.

  The air that has flowed into the intake duct 96 from the intake port 96a flows upward in the intake duct 96 from the lower intake port 96a toward the upper communication portion 97. The air moves from the inside of the intake duct 96 to the inside of the exhaust duct 98 via the communication portion 97. The air that has flowed into the exhaust duct 98 from the communication portion 97 further flows downward in the exhaust duct 98 from the upper communication portion 97 toward the lower exhaust port 98a, and is discharged from the exhaust port 98a.

  Air flows through the inside of the duct 95 so as to reach the exhaust port 98a from the intake port 96a through the intake duct 96, the communication part 97, and the exhaust duct 98 in this order. In order to form this air flow, a fan 99 is arranged at the uppermost part inside the exhaust duct 98. The fan 99 is ventilated inside the duct 95. The heat generating portion 94 that generates heat is cooled by releasing heat to the air flowing in the duct 95 when the fan 99 is driven. Heat exchange between the air flowing in the duct 95 and the heat generating portion 94 causes heat generated in the heat generating portion 94 to be discharged to the outside of the housing 6 along with the air flow. The duct 95 and the fan 99 form a heat exhaust unit that exhausts heat generated by the heat generating unit 94 of the cooling unit 93 to the outside of the housing 6.

  According to the liquid medicine supply device 1 of the present embodiment having the above-described configuration, the liquid medicine bottle 23 is installed inside the cooling case 90 cooled by the cooling unit 93, so that the housing of the liquid medicine supply device 1 is provided. The liquid medicine bottle 23 can be stored in a cold place inside the body 6. Therefore, the liquid medicine 5 that needs to be stored in a cold place can be efficiently dispensed in a short time using the liquid medicine supply apparatus 1 of the present embodiment.

  Only the internal space 91 surrounded by the cooling case 90 inside the housing 6 is cooled by the cooling unit 93. That is, only the internal space 91 that is a part of the lower space 12 in the housing 6 is cooled, and it is not necessary to cool the entire interior of the housing 6. The liquid medicine supply device 1 is formed with many paths that communicate the inside and outside of the housing 6 as represented by the lower opening 15, and it is efficient to cool the entire inside of the housing 6. It is bad and proper temperature control is difficult. Since the liquid medicine supply device 1 includes the cooling case 90, the liquid medicine 5 that needs to be stored in a cold place can be efficiently cooled in the cooling case 90, so that the energy required for cooling the liquid medicine 5 is reduced. The controllability related to cooling of the liquid medicine 5 can also be improved.

  In addition, the heat generating portion 94 is disposed in the duct 95, and the fan 99 ventilates the duct 95, so that heat is released to the air flowing through the duct 95 and the heat generating portion 94 is air-cooled. The exhaust heat generated for cooling the inside of the cooling case 90 is not radiated to the inside of the housing 6 but is radiated directly to the outside of the housing 6 via the duct 95. Thereby, it is possible to suppress the exhaust heat from the heat generating portion 94 that may cause the temperature rise inside the housing 6 from being radiated to the inside of the housing 6. It can suppress that the liquid medicine 5 is heated and the temperature of the liquid medicine 5 rises. Since the fan 99 is disposed inside the duct 95, it is not necessary to separately provide a ventilation device such as another fan outside the housing 6.

  As shown in FIG. 6, the intake port 96a is open on the back side (right side in the figure) of the liquid medicine supply device 1, and the exhaust port 98a is open on the front side (left side in the figure) of the liquid medicine supply device 1. ing. The directions in which the intake port 96a and the exhaust port 98a are opened are opposite to each other. The intake port 96a and the exhaust port 98a are formed so that the opening directions to the outside of the housing 6 are different from each other, thereby sucking the flow direction of the air discharged from the exhaust port 98a into the intake port 96a. Different from the direction of air flow. In this way, since the air exhausted from the duct 95 can be prevented from being sucked again from the intake port 96a, the duct 95 can circulate outside air having a low temperature. Therefore, the heat generating part 94 can be cooled more efficiently.

  As shown in FIG. 7, the liquid medicine supply device 1 of the present embodiment includes two cooling cases 90. One liquid medicine bottle 23 can be arranged in each internal space 91 of each cooling case 90, and a total of two liquid medicine bottles 23 can be stored in a cold place inside the liquid medicine supply apparatus 1.

  A temperature sensor (not shown) for detecting the temperature of the internal space 91 is attached to the cooling case 90. A thermistor may be used as the temperature sensor. The operation of the cooling unit 93 is controlled so that the temperature of the internal space 91 is maintained within a predetermined temperature range (for example, 8 ° C. to 12 ° C.). The cooling unit 93 may be operated continuously, or may be operated intermittently by repeatedly operating and stopping.

  A temperature sensor (not shown) for detecting the temperature of the heat generating portion 94 is attached to the inside of the duct 95. A thermistor may be used as the temperature sensor. The fan 99 is operated and the flow of air in the duct 95 is controlled so that the temperature of the heat generating portion 94 does not exceed a predetermined temperature (for example, 30 ° C.). The fan 99 may be operated continuously, or may be operated intermittently by repeatedly starting and stopping.

  The duct 95 is disposed at the center of the rotary drum 21 along the drum axis L1. A hollow prismatic member extending from the nozzle mounting plate 53 to the liquid medicine bottle holder 32 is fixed in the vertical direction below the nozzle attachment board 53, and the liquid medicine bottle holder 32 has a shape corresponding to the hollow prismatic shape. A through hole is formed, and a hollow prism-shaped member is further fixed to the lower side of the liquid medicine bottle holding body 32, and a duct 95 extending to the lower side of the bottom plate 9 of the housing 6 is formed. The duct 95 receives the rotational driving force of the drum rotating motor 22 and rotates integrally with the rotating drum 21.

  A flat cleaning plate 59 (see FIGS. 5 and 7) is disposed in the lower space 12 so as to face the bottom plate 9. The cleaning plate 59 has a circular outer shape when viewed in plan. As described above, the supply nozzle 36 is mounted on the same circumference in the outer peripheral portion of the nozzle mounting plate 53. The diameter of the circle forming the outer shape of the cleaning plate 59 is larger than the diameter of the circle to which the supply nozzle 36 is attached, as shown in FIG. Therefore, when liquid dripping occurs from the supply port 36 </ b> A of the supply nozzle 36, the dripped liquid droplet falls on the surface of the cleaning plate 59.

  A duct 95 is formed extending vertically in the central shaft portion of the rotary drum 21, and the cleaning plate 59 is formed in an annular shape in plan view in order to prevent interference with the duct 95. In the vicinity of the central portion of the cleaning plate 59, a circular through hole penetrating the cleaning plate 59 is formed, and a duct 95 is disposed so as to penetrate the through hole. The annular plate-shaped cleaning plate 59 is not fixed to the rotating drum 21, and the cleaning plate 59 does not rotate integrally with the rotating drum 21. On the other hand, the cleaning plate 59 is not fixed to the housing 6. Therefore, the cleaning plate 59 can be manually rotated around the duct 95.

  An operator who operates the liquid medicine supply device 1 extends his hand to the cleaning plate 59 by inserting his hand into the lower space 12 from the lower opening 15 on the front side of the liquid medicine supply device 1, and It is possible to wipe off droplets that have fallen on the surface. As shown in FIG. 10 to be described later, by moving the mounting table 48 to the supply position, the accessibility to the cleaning plate 59 is improved, and the operator can easily reach the cleaning plate 59. At this time, since the cleaning plate 59 is provided so as to be manually rotatable, the operator can clean the entire cleaning plate 59 while rotating the cleaning plate 59. Since the liquid droplets dropped on the cleaning plate 59 can be completely wiped off and the liquid drops dripping inside the housing 6 can be easily removed, it is hygienic and prevents rust from being generated due to the liquid droplets.

The air filter 69 may be a HEPA filter, for example. On the top plate 10 side of the housing 6, a fan cover 67 is provided so as to cover the fan 68 and forms a flow path of air flowing to the fan 68. The fan cover 67 has a muffler function that reduces the operation sound generated by the fan 68 and suppresses the operation sound from leaking outside the liquid medicine supply device 1.

  Air outside the apparatus is ventilated inside the housing 6 by the fan 68. At this time, since the air passes through the air filter 69, fine particles contained in the air are removed, and the cleanliness of the air is improved. If the fan 68 is continuously operated so that air is continuously transferred into the housing 6, the air pressure inside the housing 6 becomes higher than the air pressure outside the housing 6, and the inside of the housing 6 is positive. Since the pressure is increased, an air flow from the inside of the housing 6 to the outside is generated.

  Thereby, the floating microbe contained in the air around the liquid medicine supply device 1 can be prevented from entering the housing 6 from the lower opening 15 or the like, for example. Therefore, by supplying the air that has passed through the air filter 69 to the inside of the housing 6, the air cleanliness inside the housing 6 can be improved and the propagation of germs and viruses inside the housing 6 can be suppressed. it can.

  In addition, when air flows from the inside of the housing 6 toward the outside, it is possible to prevent dust from being brought into the inside of the housing 6 by riding on the air flow. Since the intrusion of dust into the housing 6 can be prevented and the dust can be discharged to the outside of the housing 6 together with the air flow without retaining the dust inside the housing 6. The interior can be kept in a more hygienic environment.

  FIG. 9 is a schematic view showing the flow of air inside the housing 6. FIG. 9 shows the same cross section as FIG. 4 of the liquid medicine supply device 1, and the white arrow in FIG. 9 indicates the flow of air inside the housing 6. As shown in FIG. 9, the air flowing into the upper space 11 of the housing 6 by the fan 68 passes through the air filter 69 and flows into the space inside the pump holder 31 of the rotary drum 21. The air further flows to a space outside the pump holding body 31 through the blower outlet 70 formed in the pump holding body 31. In this way, clean air that has passed through the air filter 69 is supplied to the lower space 12 inside the housing 6.

  The air flowing out from the air outlet 70 flows radially outward of the rotating drum 21, that is, in a direction away from the drum axis L1, and reaches the periphery of the supply nozzle 36. Thereafter, the flow direction of the air changes downward, and the air flows through a region inside the housing 6 where the supply port 36A at the tip of the supply nozzle 36 is disposed.

  The liquid medicine 5 is poured out from the liquid medicine bottle 23, circulates to the supply nozzle 36, and is supplied into the prescription bottle 2 from the supply port 36A. After the supply of the liquid medicine 5 to the prescription bottle 2 is completed, various bacteria or viruses are likely to propagate in the liquid medicine 5 slightly remaining in the supply port 36A. Therefore, it is necessary to keep the supply port 36A of the supply nozzle 36 where bacteria or viruses easily propagate clean. In the present embodiment, an air outlet 70 is formed in the vicinity of the supply nozzle 36 to form a flow of air flowing toward the supply nozzle 36. With this configuration, since clean air is supplied to the area around the supply port 36A via the air filter 69, the air cleanliness around the supply port 36A is increased. Therefore, it is possible to effectively suppress the propagation of germs or viruses in the supply port 36A where the germs or viruses are particularly likely to propagate inside the housing 6.

  The air flowing through the area around the supply port 36 </ b> A then flows below the nozzle mounting plate 53, and a part of the air flows out of the housing 6 from the lower opening 15. A part of the air flows along the surface of the duct 95.

  As described above, the heat generating portion 94 is disposed inside the duct 95, and air heated by exchanging heat with the heat generating portion 94 circulates in the duct 95. The surface of the duct 95 may be heated by heat transferred from the air flowing through the heat generating portion 94 or the duct 95. In that case, if an air flow along the outer surface of the duct 95 is formed, the heat flow from the duct 95 can flow out of the housing 6 by the air flow, and the surface of the duct 95 is cooled. Therefore, heat radiation from the duct 95 into the lower space 12 can be reduced.

  When the heat generating part 94 that generates heat is disposed inside the housing 6 and the heat generated by the heat generating part 94 is discharged to the outside of the housing 6 via the duct 95, the fan 68 generates a heat inside the housing 6. By flowing the supplied air along the surface of the duct 95, the surface of the duct 95 can be cooled. Therefore, the liquid medicine bottle 23 not accommodated in the cooling case 90 or other components of the liquid medicine supply device 1 can be prevented from being heated by heat radiation from the duct 95.

  The air that has flowed along the surface of the duct 95 to the vicinity of the bottom plate 9 of the housing 6 passes through the lower opening 15 below the casing 46 that constitutes the weight detection means 4 and is installed in which the liquid medicine supply device 1 is installed. It flows in a direction parallel to the surface and flows out of the casing 6 on the front side of the liquid medicine supply device 1. The air heated by cooling the surface of the duct 95 and exchanging heat with the duct 95 does not flow to the side where the air inlet 96 a to the duct 95 is opened. For this reason, it is possible to prevent the heated air whose temperature has been increased from flowing into the duct 95, so that the cooling efficiency of the heat generating portion 94 can be suppressed from decreasing.

  FIG. 10 is a cross-sectional view showing a state in which the medication bottle 2 is moved to the supply position. FIG. 10 shows the same cross section as FIG. 4 of the liquid medicine supply device 1, and the medication bottle 2 placed on the placement table 48 is lifted using the above-described lifting device 50, and the medication is dispensed. The state which moved the prescription bottle 2 to the supply position which supplies the liquid medication 5 to the bottle 2 is shown.

  As shown in FIG. 10, when arranged in the supply position, the opening 2 </ b> A of the prescription bottle 2 is arranged behind the front cover 18 and is located inside the housing 6. On the other hand, when arranged in the supply position, a part of the bottom side that contacts the mounting table 48 of the prescription bottle 2 is located outside the housing 6. By disposing only a part of the medication bottle 2 necessary for supplying the liquid medicine 5 into the medication bottle 2 in the housing 6 and not moving the entire medication bottle 2 into the housing 6, the medication bottle 2. It is possible to suppress the introduction of germs or viruses attached to the housing 6 into the housing 6. Therefore, the propagation of germs or viruses inside the housing can be further suppressed.

  At this time, as described above, clean air flows in the area around the supply port 36A of the supply nozzle 36, and this clean air also flows around the opening 2A of the prescription bottle 2. Since the liquid medicine 5 can be supplied to the prescription bottle 2 in an atmosphere in which airborne bacteria contained in the air are reduced, the liquid medicine 5 flowing into the prescription bottle 2 from the supply port 36A through the opening 2A is caused by various bacteria or viruses. It is possible to suppress contamination.
