  Next, based on FIGS. 7 and 8, the mounting table 24 on which the liquid medicine bottle 4 is mounted and the lifting device 25 for lifting the mounting table 24 with respect to the supply nozzle 22 will be described. The mounting table 24 is disposed at the lower front portion of the main body 6 and is guided by the side wall portions 75 and 76 of the rectangular cutout 74 when viewed from the front when the lower front portion is cut from the top to the bottom. A guide plate member 77, a fixed base 78 fixed to project forward from the lower front surface of the guide plate member 77, and the liquid medicine bottle 4 placed directly on the upper surface of the fixed base 78, and the liquid medicine bottle 4 And a receiving plate 81 having a recess 80 into which the bottom of the plate is inserted.

  The elevating device 25 includes an elevating motor 82 and a belt mechanism 83 that is disposed in the lower front portion of the main body 6 and is driven by driving of the elevating motor 82. The raising / lowering motor 82 is attached to the back surface of the lower front portion of the main body 6 so that the drive shaft 84 projects forward, and the drive pulley 85 projects from the lower front surface of the main body 6 to the front in the horizontal direction. Installed on. The belt mechanism 83 includes a belt fixing tool 86 fixed to a side portion of the guide plate member 77, a tension pulley 87 disposed obliquely below the drive pulley 85, and a winding pulley disposed separately in the vertical direction. 90, 91 and a belt 92 wound around each pulley 85, 87, 90, 91. The belt 92 may be a timing belt, and each of the pulleys 85, 87, 90, 91 may have an uneven portion that meshes with the timing belt. Furthermore, it is preferable that the tension pulley 87 is configured to swing around a swing shaft (not shown) and to apply an appropriate tension to the belt 92. The lifting device 25 is driven by operating a drive switch (not shown).

  Next, the liquid medicine sensor 27 as an optical sensor for detecting the presence or absence of the liquid medicine 2 discharged from the liquid medicine discharge port portion 26 of the supply nozzle 22 will be described. The liquid medicine sensor 27 has a light emitting portion 95 and a light receiving portion 96 on the lower surfaces of the left and right facing surfaces 93a and 94a of the mounting plates 93 and 94 that are separated from each other so as to protrude forward in the lower part of the front surface of the main body 6. The main body of the liquid medicine sensor 27 is attached by screwing or the like so as to have the same height.

  The mounting plates 93 and 94 are located slightly below the mounting body 5 when viewed from the front. The bottom plate 8 is mounted on the main body 6 via a gap (space) having a height in the vertical direction in which at least fingers and a manufacturing tool can enter, further below the mounting body 5.

  With this configuration, the liquid medicine sensor 27 is disposed in the vicinity of the side of the supply nozzle 22 (liquid medicine discharge port portion 26). In addition, you may attach the light emission part 95 and the light-receiving part 96 to either of the left-right opposing surfaces 93a and 94a. In the liquid medicine sensor 27, the amount of light received by the light receiving unit 96 with respect to the amount of light emitted from the light emitting unit 95 side is related in advance. Since the relationship between the amounts collapses, it is directly detected whether or not the liquid medicine 2 is discharged.

  The liquid medicine sensor 27 also has a function of detecting the presence or absence of the upper end opening 97 of the liquid medicine bottle 4 between the light emitting part 95 and the light receiving part 96, that is, whether or not the liquid medicine 2 can be supplied to the liquid medicine bottle 4. Yes. When the liquid medicine sensor 27 detects the presence of the liquid medicine bottle 4, the signal is output to the drive unit of the lifting / lowering motor 82 via the control device, and the upper end opening 97 of the liquid medicine bottle 4 is transferred from the liquid medicine sensor 27. It is controlled by the control device to lower the mounting table 24 until it is positioned slightly below. Thus, by positioning the upper end opening 97 of the liquid medicine bottle 4 slightly below the liquid medicine sensor 27, a detection space can be secured between the liquid medicine sensors 27. Since only the presence or absence is detected, the liquid medicine 2 can be accurately detected. The liquid medicine sensor 27 is electrically connected to the drive unit of the lifting motor 82, the drive unit of the rotation drive motor 28, and the drive unit of each supply pump 18.

  In the liquid medicine supply device 1 having the above-described configuration, the supply bottle 3 filled with the liquid medicine 2 is placed on each mounting tray 57 of the mounting body 5, and one end side of each liquid medicine supply pipe 21 is connected to the supply bottle 3. The other end side is connected to the relay nozzle 19, and one end side of the liquid medicine pipe 29 is connected to the relay nozzle 19 and the other end side is supplied to the supply nozzle 22. Connect to. In addition, the liquid medicine bottle 4 is placed on the receiving tray 81 on the fixed base 78.

When the liquid medicine sensor 27 does not detect the upper end opening 97 of the liquid medicine bottle 4 by operating the drive switch (ON operation), the elevating device 25, that is, the elevating motor 82 is driven. 92 rotates and the belt 92 and the guide plate member 77 are fixed via the belt fixture 86, so that the guide plate member 77 is raised and the liquid medicine sensor 27 detects the upper end opening 97 of the liquid medicine bottle 4. At that time, the lifting device 25 (lifting motor 82) stops driving, and the mounting table 24 is lowered until the upper end opening 97 of the liquid medicine bottle 4 is positioned slightly below the liquid medicine sensor 27 as described above. . With respect to the inclination angle θ of the supply nozzle 22, the circumferential position and the height direction position of the second long hole 73 with respect to the first long hole 64 are adjusted, so adjust the angle of inclination, in accordance with the shape of the liquid medicine bottle 4, it is preferable to set to be discharged obliquely to advance potions bottle 4 (upper opening portion 97).

In this way, the preparation of the liquid medicine 2 is started and the supply of the liquid medicine 2 is started. In the initial state, the liquid medicine 2 is supplied to the liquid medicine bottle 4 with the supply bottle 3, that is, the supply nozzle 22 in the circumferential direction. It is good if it is in a possible position, but it is also possible if it is not. For such a case, when the switch (not shown) for driving the main body is operated (ON operation), the rotation drive motor 28 is driven so that the supply bottle 3, that is, the supply nozzle 22 closest to the liquid medicine bottle 4 is moved. The mounting body 5 is rotated in a circumferential direction until reaching the position where the liquid medicine 2 can be supplied to the liquid medicine bottle 4 . In this case, a sensor that specifically detects the position is provided, and the supply bottle 3 closest to the liquid medicine bottle 4 can supply the liquid medicine 2 to the liquid medicine bottle 4 by the control device based on a detection signal from the sensor. It is preferable to rotate the mounting body 5 until it reaches a certain position. At this time, when the rotational drive motor 28 is driven, the drive gear is rotationally driven, and the drive gear 33 a is engaged with the teeth 33 of the gear plate 32, so that the rotary ring 31 provided integrally with the gear plate 32 is provided. The protrusion 30 is rotationally driven around the vertical axis 16 while being engaged with the recess 34 of the support roller 35. Further, the mounting frame 36, the supply pump 18, the nozzle mounting plate 53, the partition 56, and the mounting body 5 that are integrally provided below the gear plate 32 rotate around the vertical axis 16.

  In the pump drive unit 20, the solenoid 48 is driven and the servo motor 46 advances laterally toward the driven gear 41 of the supply pump 18 against the elasticity of the spring 50, and the drive gear 47 is engaged with the driven gear 41 ( When the position detection sensor 51 detects that the engagement has occurred, the servo motor 46 is driven, the driven gear 41 is rotated together with the drive gear 47, and the supply pump 18 is driven. When the supply pump 18 is driven, the liquid medicine 2 in the supply bottle 3 is sucked up, passes from the liquid medicine supply pipe 21 through the relay nozzle 19 to the liquid medicine pipe 29, and further, the liquid medicine discharge port portion of the supply nozzle 22. The liquid medicine 2 is discharged from 26. At this time, since the supply nozzle 22 is inclined with respect to the vertical axis 16, the supply nozzle 22 does not hit the bottom surface of the liquid medicine bottle 4 at a right angle. For example, the supply nozzle 22 is discharged obliquely with respect to the inner wall surface of the liquid medicine bottle 4. I will win. That is, the bubble of the liquid medicine 2 associated with the water impact phenomenon is reduced by the amount of slanting against the inner wall surface of the liquid medicine bottle 4, and the liquid medicine 2 effectively foams in the liquid medicine bottle 4. Therefore, the amount of the liquid medicine 2 in the liquid medicine bottle 4 can be easily confirmed.

  Depending on the inclination angle of the supply nozzle 22, the liquid medicine 2 may hit the mouth part 4 c and the neck part 4 b of the liquid medicine bottle 4, but in any case, it prevents the liquid medicine bottle 4 from hitting the inner surface of the liquid medicine bottle 4 at right angles. If it does so, since the foaming of the liquid medicine 2 can be suppressed compared with the case where it hits the direction orthogonal to the bottom face conventionally, it is easy to confirm the quantity of the liquid medicine 2 in the liquid medicine bottle 4.

When the liquid medicine 2 is supplied to the liquid medicine bottle 4, the amount of the liquid medicine 2 is increased at the start of supply (the liquid medicine discharge port portion 26 has the same diameter so that the discharge speed of the liquid medicine 2 is increased). In other words, the closer the supply is to the end, the smaller the supply (the discharge speed of the liquid medicine 2 is reduced). If it does so, scattering of the liquid medicine 2 to the outside of the liquid medicine bottle 4 can be suppressed, dirt around the liquid medicine bottle 4 can be suppressed, and accordingly, the substantial amount of the liquid medicine 2 supplied into the liquid medicine bottle 4 by that much is reduced. Can be accurate. For this reason, in embodiment of this invention, it controls by the control apparatus so that the supply amount of the liquid medicine 2 may be changed as mentioned above.

  In addition, in order to suppress more reliably the foaming of the liquid medicine 2 by the water-impact phenomenon in an initial state, it is also possible to reduce the quantity of the liquid medicine 2 in an initial supply state. In this case, the liquid medicine 2 is supplied in a large amount until the supply of the liquid medicine 2 approaches, and at the time when the supply closes to the end of the supply, the supply amount of the liquid medicine 2 is controlled again so that the liquid medicine 2 is reduced. The supply time can be shortened, and scattering of the liquid medicine 2 to the outside of the liquid medicine bottle 4 can be suppressed.

  By the way, conventionally, although the supply pump 18 is driven, for example, the liquid medicine 2 in the supply bottle 3 is insufficient, or the liquid medicine 2 leaks from the relay nozzle 19, and the supply nozzle 22. Even if the liquid medicine 2 is not discharged from the control device, the controller determines that the liquid medicine 2 is discharged from the supply nozzle 22 by detecting the drive of the supply pump 18. In the embodiment, whether or not the liquid medicine 2 is actually discharged from the supply nozzle 22, that is, the presence or absence of the liquid medicine 2 is detected based on the received light amount signal from the liquid medicine sensor 27, thus eliminating the above inconvenience. It is possible to reliably know whether or not the liquid medicine 2 is discharged from the supply nozzle 22. Furthermore, since the liquid medicine sensor 27 also serves as a sensor for detecting whether or not the position of the liquid medicine bottle 4 can supply the liquid medicine 2, it is necessary to provide a sensor for specifically detecting the position of the liquid medicine bottle 4. As a result, the structure becomes simple and the cost can be reduced.

  By the way, for example, when the liquid medicine 2 in the supply bottle 3 runs out or when another liquid medicine 2 is accommodated in one liquid medicine bottle 4, another supply bottle 3 filled with the liquid medicine 2 in advance. Will be used. In this case, the drive of the pump drive unit 20 is stopped once, the drive of the servo motor 46 is stopped, the rotation of the driven gear 41 is stopped, and the drive of the solenoid 48 is stopped. Then, the servo motor 46 returns to the reference position due to the elasticity of the spring 50. Subsequently, the rotation drive unit 17 (rotation drive motor 28) is intermittently driven to use the next supply pump 18 (the same liquid medicine 2 or different liquid medicine 2 may be accommodated). The mounting body 5 is rotated around the vertical axis 16 so that the supply pump 18 to be used, that is, the supply nozzle 22 reaches a position corresponding to the liquid medicine bottle 4. Then, as described above, the liquid medicine 2 is discharged from the supply nozzle 22 by driving the pump drive unit 20.

  When the liquid medicine 2 according to the prescription is supplied to one liquid medicine bottle 4, the next liquid medicine bottle 4 is placed on the receiving pan 81, and the height position of the liquid medicine bottle 4 is adjusted and supplied in the same manner as described above. The liquid medicine 2 is supplied from the nozzle 22 to the liquid medicine bottle 4. At this time, as described above, since the liquid medicine 2 is prevented from being scattered, contamination around the new liquid medicine bottle 4 such as the tray 81 is prevented, so that it is possible to particularly save the trouble of cleaning.

The above operation is repeated to supply the liquid medicine 2 to the liquid medicine bottle 4, but when replacing the supply bottle 3, the liquid medicine supply pipe 21, the relay nozzle 19, the liquid medicine pipe 29, etc. The liquid medicine 2 may spill onto the bottom plate 8 or the like. In this embodiment, the mounting body 5 on which the supply bottle 3 is mounted has a configuration in which it is suspended on the top plate 7 side of the main body 6, and there is a gap between the bottom plate 8 of the main body 6 and the mounting body 5. 10 is provided, it is easy to move fingers and cleaning tools on the bottom plate 8, and there is nothing between the bottom plate 8 and the mounting body 5 having a complicated structure portion as in the prior art. Therefore, the liquid medicine 2 that has fallen down can be easily and easily cleaned. Therefore, it becomes possible to always maintain the liquid medicine supply device 1 in a clean state.
