JP 2007-14618 A

  In the above-mentioned Patent Document 1, when the drug solution is put into the prescription bottle, the prescription bottle is raised and the discharge port of the discharge pipe of the drug bottle is inserted into the prescription bottle. Not only does this take a lot, but when another type of drug solution is put into the prescription bottle, the lowering prescription bottle is once raised until the discharge port of the discharge tube is located outside, and the next drug solution is charged. As a result, it takes a lot of time to raise the prescription bottle. As a result, especially when a plurality of types of chemical solutions are added, it takes a lot of time to dispense.

Incidentally, if the discharge port of the discharge tube is always positioned above the prescription bottle so as to be close to the opening of the prescription bottle, the time for raising and lowering the prescription bottle is unnecessary, but there are the following disadvantages.
That is, since the distance from the opening of the prescription bottle to the discharge port of the discharge tube is short, for example, when supplying the liquid medicine in the third prescription bottle after the supply of the liquid medicine in the first medicine bottle is completed, 2 When the second medicine bottle passes over the medication bottle, if a drop-shaped medicine solution (medical solution other than the target) hangs down at the outlet of the second medicine bottle discharge tube, In some cases, the medicine may accidentally enter the prescription bottle in contact with the upper opening edge.
For this reason, it can be considered that the discharge port of the discharge pipe is greatly separated from the opening of the prescription bottle. However, since the injection distance of the chemical liquid becomes long, the inconvenience that the chemical liquid to be introduced easily bubbles in the prescription bottle. Yes, it was difficult to implement.

  The object of the present invention is to provide a chemical solution that can shorten the dispensing time but can not only enter the chemical solution other than the target chemical solution into the charging container but also can input the chemical solution in a state where foaming is difficult to occur. Is to provide a device.

  The present invention relates to a plurality of chemical liquid containers in which chemical liquids are stored, a supply nozzle provided corresponding to each of the plurality of chemical liquid containers, and a chemical liquid for supplying the chemical liquid in the chemical liquid container to the input container via the supply nozzle A chemical supply apparatus comprising: a supply means; and a moving means for moving at least one of the supply nozzle and the input container in a horizontal direction so that a supply port of the supply nozzle faces the opening of the input container. The supply port of the nozzle and the opening of the charging container are positioned at a standby position separated by a predetermined distance and a supply position where the chemical solution is supplied at a position closer to the both than the standby position. Elevating means for moving at least one of the supply nozzles in the height direction is provided, and the supply nozzle and the input container are positioned at the standby position before the supply port of the supply nozzle passes above the opening edge of the input container. As to, it is characterized by driving the lifting means.

  As described above, before the supply port of the supply nozzle moved by the moving means passes above the opening edge of the input container, the supply nozzle and the input container are positioned at a standby position separated from the input container opening. As described above, by driving the elevating means, the chemical liquid hanging as water droplets at the supply port of the supply nozzle does not come into contact with the opening edge of the charging container. In addition, after the supply port of the supply nozzle passes above the opening edge of the input container and faces the opening of the input container, the chemical solution is introduced closer to the input container from the supply port of the supply nozzle than the standby position. By being located at the supply position, it is possible to make it difficult for the chemical solution supplied from the supply port of the supply nozzle to foam in the input container. Further, the supply nozzle of the supply nozzle is not inserted into the charging container when the chemical solution is supplied, and the supply port of the supply nozzle is positioned at a standby position that is spaced a predetermined distance from the opening of the charging container and a supply position that is closer to the standby position than the standby position. Therefore, the dispensing time can be shortened.

  The axis of the supply nozzle may be inclined with respect to the vertical axis of the charging container.

  It is preferable that the distance between the supply port of the supply nozzle and the opening of the charging container at the standby position is set to 5 mm or more.

  One end of a tube is connected to the supply nozzle, the other end of the tube is inserted into the chemical liquid container, the chemical liquid supply means is provided movably by the moving means, and presses a part of the tube. A plurality of tube pumps for transferring the chemical liquid to the supply nozzle and a pump drive unit for driving the tube pump, and the tube pump has a rotatable rotor provided with a plurality of rollers on the outer periphery. The pump drive unit has a connecting portion connected to the connected portion of the rotor so as to rotate the rotor of the specific tube pump that has moved, and a drive shaft for the pump driving motor. For moving the connecting portion of the motor to the connected portion of the rotor of the tube pump and switching the connecting state to the released state. A Chueta may be configured to drive said lifting means in synchronism with the movement of the motor pump driven by the actuator.

  In a state where the supply ports of all the supply nozzles do not face the opening of the input container, the supply means of the predetermined supply nozzle are synchronized with the movement of the supply nozzle by the moving means so as to face the opening of the input container. The elevating means may be driven.

  The plurality of chemical liquid containers, the corresponding tubes and the supply nozzles are provided in a rotating body that is rotatable around an axis in the vertical direction, and by rotating the rotating body, the supply port of the supply nozzle becomes the input container You may comprise so that it may face the opening of this.

According to the present invention, the supply port of the supply nozzle and the opening of the input container are positioned at a standby position separated by a predetermined distance, so that the chemical liquid hanging as water droplets on the supply port of the supply nozzle can be opened. It is possible to provide a highly reliable chemical solution supply apparatus that does not come into contact with the chemical solution and does not allow any other chemical solution to enter the charging container.
In addition, when the chemical solution is supplied from the supply port of the supply nozzle to the input container after the supply port of the supply nozzle has faced the opening of the input container, the both are positioned closer to the supply position than the standby position. The chemical liquid supplied from the supply port of the supply nozzle can be made difficult to foam in the charging container.
Furthermore, since the supply port of the supply nozzle only needs to be positioned at a standby position that is a predetermined distance away from the opening of the input container and a supply position that is closer to both than the standby position, the chemical supply device that can shorten the dispensing time Can be provided.

  By tilting the axis of the supply nozzle with respect to the vertical axis of the input container, the chemical solution from the supply nozzle can be applied to the inner surface of the side wall of the input container. Compared with the case where the chemical solution is introduced while being applied to the liquid, foaming of the chemical solution can be further prevented from occurring.

  By configuring the lifting / lowering means in synchronization with the movement of the pump driving motor by the actuator, the time can be shortened compared to the case of driving the lifting / lowering means after the movement of the pump driving motor is completed. Can be planned.

  In a state where the supply ports of all the supply nozzles do not face the opening of the input container, the supply means of the predetermined supply nozzle are synchronized with the movement of the supply nozzle by the moving means so as to face the opening of the input container. By configuring the control unit to drive the lifting / lowering means, the time can be shortened compared to the case of driving the lifting / lowering means after the movement of the supply nozzle is completed.

  For example, the connecting member 42 and the connected member 44 can be connected by advancing the moving part 38 by driving the moving motor 39 in the forward rotation direction. Further, the connection between the connecting member 42 and the connected member 44 can be released by retracting the moving portion 38 by driving the moving motor 39 in the reverse direction. In the disconnected state, the rotary drum 21 can be rotated with respect to the support frame 8. Therefore, by driving the drum rotating motor 22 in the disconnected state, the rotating drum 21 is rotated to a position where the specific pump 24 selected by the prescription information input to the control unit S faces the pump driving motor 40. Then, by switching to the connected state after rotation, the selected specific pump 24 can be driven, and the drug solution supplied from the desired drug solution supply means 3 can be put into the prescription bottle 2. The connecting member 42 and the connected member 44 are both configured by gears, but may have any configuration as long as power can be transmitted.

  The weight detection means 4 is disposed in the lower opening 15. The weight detection means 4 includes an electronic balance 45, a casing 46 that houses the electronic balance 45, and a prescription bottle holder 47 that is placed and fixed on the electronic balance 45 and holds the prescription bottle 2 in an upright state.

The electronic balance 45 is a tuning fork type. The electronic balance 45 may be a load cell type or an electromagnetic type. The casing 46 is provided below the left and right side portions 16 a and 16 b in the front surface portion 13 of the housing 6. The prescription bottle holder 47 includes a mounting table 48 on which the prescription bottle 2 is mounted, and a holder 49 that is provided on the mounting table 48 and holds the prescription bottle 2.

The mounting table 48 and the casing 46 on which the prescription bottle 2 is mounted can be moved up and down by the lifting means 50 shown in FIG.
The elevating means 50 includes an elevating electric motor 51 and a belt mechanism driven by the electric motor 51. The belt mechanism includes a belt fixture 52 fixed to one side wall of the casing 46, an endless belt 55 wound around a driving pulley 51A of the electric motor 51 and pulleys 53 and 54 arranged above and below, A tension pulley 56 that applies tension to the belt 55 is provided. Accordingly, the mounting table 48 and the casing 46 can be moved up and down by rotating the belt 55 by driving the electric motor 51.

The upper end opening 2 </ b> A is close to the standby position, and the prescription bottle 2 and the supply nozzle 36 are closer to the standby position than the standby position, and can be positioned at three positions for supplying the chemical solution. .

  Sensors 57 for detecting that the prescription bottle 2 is located at the three positions are arranged. Each sensor 57 is composed of a photoelectric sensor composed of a light emitting section 57A and a light receiving section 57B. However, each sensor 57 may be composed of a magnetic or ultrasonic sensor or a contact type limit sensor. Is possible. Further, in FIG. 5B, the three positions are respectively detected by three sensors. However, in order to detect the distance from the upper end of the prescription bottle 2 with a single sensor of magnetic type or ultrasonic type, It may be arranged above the prescription bottle 2. Moreover, you may comprise so that the height position of the prescription bottle 2 can be detected based on the rotation speed of an encoder by using an electric motor with an encoder or attaching an encoder externally to the electric motor. In this case, if an arithmetic device that calculates the height position of the prescription bottle 2 according to the height of the prescription bottle 2 is provided, there is an advantage that the prescription bottle 2 having a plurality of types of heights can be handled. .

  As shown in FIG. 5A, the chemical solution supply apparatus 1 includes a control unit S configured by a computer or the like for controlling the moving unit 22 and the lifting unit 50. Therefore, the controller S determines that the supply nozzle 36A is in a standby position before the supply port 36A of the supply nozzle 36 moved by the moving means 22 is located at the position facing the opening 2A of the prescription bottle 2 (FIG. 5A). The elevating means 50 is driven so as to be positioned at a position indicated by a solid line.

  By configuring in this way, the drug solution hanging as water droplets at the supply port 36A of the supply nozzle 36 that has moved along with the rotation of the rotary drum 21 may come into contact with the edge of the opening 2A of the prescription bottle 2. Absent. Therefore, no other chemical solution enters the prescription bottle 2 by mistake during dispensing. If the distance between the supply port 36A of the supply nozzle 36 and the opening 2A of the prescription bottle 2 is set to 5 mm or more at the standby position, it is possible that other chemicals will enter the prescription bottle 2 by mistake during dispensing. It can be surely prevented. Further, the distance between the supply port 36A of the supply nozzle 36 and the opening 2A of the prescription bottle 2 at the supply position is preferably short, but any value can be set as long as it is shorter than the distance at the standby position. May be. The opening 2A of the prescription bottle 2 refers to a circular opening (may be another shape such as a square, a triangle, or a polygon) formed inside the upper end of the prescription bottle 2, and the medicine that forms the opening 2A The upper end part of the bottle 2 is called an opening edge.

  Next, control when dispensing to the prescription bottle S by the control unit S will be described based on the flowcharts of FIGS.

  First, when the prescription bottle 2 is set on the mounting table 48 and a switch (not shown) for starting dispensing start control is turned on, as shown in FIG. It outputs to the raising / lowering means 50 (step S1). At this time, the control unit S performs the ascending operation of the prescription bottle 2 according to another flowchart shown in FIG. In other words, when there is an instruction to raise the prescription bottle 2 (step S21), the operation of raising the prescription bottle 2 is entered, and when the raising of the prescription bottle 2 is completed, a completion notification is given (step S24). The raising operation of the prescription bottle 2 is shown in the subroutine shown in FIG. In the ascending operation, the raising of the prescription bottle 2 is started (step S31), it is determined whether or not the prescription bottle 2 is located at the supply position (step S32), and when the prescription bottle 2 reaches the supply position, the prescription bottle 2 is reached. Is stopped (step S33).

  When the control unit S receives the notification of the completion of the increase and determines that the rising of the prescription bottle 2 is completed (step S2), it outputs a retraction instruction (step S3) and supplies the supply nozzle 36 of the drug solution bottle 23 to be dispensed. The rotary drum 21 is rotated so that the mouth 36A is located at the position facing the opening 2A of the prescription bottle 2 (step S4).

  When the withdrawal instruction is output, the control unit S performs the withdrawal operation of the prescription bottle 2 according to another flowchart shown in FIG. That is, when there is an instruction to retract the prescription bottle 2 (step S22), the operation of retreating the prescription bottle 2 is entered, and when the retraction of the prescription bottle 2 is completed, a completion notification is given (step S24). The retraction operation of the prescription bottle 2 is shown in the subroutine shown in FIG. In the retracting operation, the lowering of the prescription bottle 2 is started (step S41), it is determined whether or not the prescription bottle 2 is located at the standby position (step S42), and when the prescription bottle 2 reaches the standby position, the prescription bottle 2 is reached. Is stopped (step S43).

  Subsequently, when the rotation of the rotary drum 21 is completed, the control unit S outputs an instruction to raise the prescription bottle 2 (Step S5), and advances the pump driving motor 40 (Step S6). When an instruction for raising the prescription bottle 2 is output, as described above, an operation for raising is performed by another flowchart shown in FIG. 7 and a subroutine shown in FIG.

  When the control unit S receives the notification of the completion of the rise and determines that the rise of the prescription bottle 2 has been completed (step S7), the control unit S rotates the pump 24 (step S8) and puts a predetermined amount of drug solution into the prescription bottle 2 To do.

  The control unit S determines whether or not all the chemicals have been introduced (step S9), and when determining that all the chemicals have been introduced, outputs a lowering instruction for the prescription bottle 2 (step S10). If it is determined that the lowering of the prescription bottle 2 has been completed (step S11), the dispensing control is terminated.

  When the lowering instruction is output, the control unit S performs the lowering operation of the prescription bottle 2 according to another flowchart shown in FIG. That is, when there is an instruction to lower the prescription bottle 2, the lowering operation of the prescription bottle 2 is performed. That is, when there is an instruction to lower the prescription bottle 2 (step S23), the lowering operation of the prescription bottle 2 is started, and when the lowering of the prescription bottle 2 is completed, a completion notification is given (step S24). The lowering operation of the prescription bottle 2 is shown in the subroutine shown in FIG. In the lowering operation, the lowering of the prescription bottle 2 is started (step S51), it is determined whether or not the prescription bottle 2 is located at the initial position (step S52), and when the prescription bottle 2 reaches the initial position, the prescription bottle 2 is reached. Is stopped (step S53).

  When the control unit S determines that all the chemical solutions are not charged in step S9 of FIG. 6, the dispensing operation from the next chemical solution bottle 23 is performed. That is, by outputting a withdrawal instruction for the prescription bottle 2 (step S12) and lowering the prescription bottle 2 to the standby position, as described above, the supply port 36A of the supply nozzle 36 that has moved along with the rotation of the rotary drum 21. Thus, the drug solution hanging as a water droplet does not come into contact with the edge of the opening 2A of the prescription bottle 2 so that another drug solution does not accidentally enter the prescription bottle 2 during dispensing.

  After the withdrawal instruction for the prescription bottle 2 is output, the pump driving motor 40 is retracted (step S13), and then the rotating drum 21 is rotated (step S4), and the dispensing operation is performed in the same manner as described above. .

  Furthermore, the control when dispensing by the control unit S will be described based on the time charts of FIGS. 9 and 10.

  First, when the prescription bottle 2 is set on the mounting table 48 and a switch (not shown) for starting dispensing start control is turned on, the prescription bottle 2 at the initial position is raised at a predetermined acceleration.

  When the prescription bottle 2 is raised and the prescription bottle 2 reaches the supply position, the ascending operation is stopped, and the prescription bottle 2 is lowered until the prescription bottle 2 is located at the standby position after the set time has elapsed. Simultaneously with the start of the lowering of the prescription bottle 2, the rotary drum 21 is rotated so that the supply port 36A of the supply nozzle 36 of the drug solution bottle 23 to be dispensed is positioned at a position facing the opening 2A of the prescription bottle 2.

  Thus, by starting the rotation of the rotating drum 21 simultaneously with the start of the lowering of the prescription bottle 2, the time required for dispensing is reduced compared to the configuration in which the rotation of the rotating drum 21 is started after the lowering of the prescription bottle 2 is completed. There is an advantage that can be shortened.

  After the supply port 36A of the supply nozzle 36 of the drug solution bottle 23 to be dispensed is positioned so as to face the opening 2A of the prescription bottle 2, the prescription bottle 2 is placed in the supply position after the set time has elapsed. Simultaneously with the start of the ascent, the pump drive motor 40 starts to advance.

  In this way, by starting the advancement of the pump driving motor 40 simultaneously with the start of the raising of the prescription bottle 2, the dispensing is compared with the configuration in which the advancement of the pump driving motor 40 is started after the raising of the prescription bottle 2 is completed. There is an advantage that the time required for the process can be shortened.

  After the set time elapses after the advance of the pump drive motor 40 is completed (or at the same time as the completion), the pump 24 is rotated to put a predetermined amount of the drug solution into the prescription bottle 2.

  When it is desired to add another chemical solution after the rotation of the pump 24 is stopped and the chemical solution has been charged, the medication bottle 2 in the supply position is placed in the standby position as shown in FIG. At the same time that the bottle 2 starts to descend, the pump drive motor 40 starts to move backward.

  Thus, the dispensing of the pump driving motor 40 is started simultaneously with the start of the lowering of the prescription bottle 2, thereby dispensing the pump driving motor 40 after the lowering of the prescription bottle 2 is completed. There is an advantage that the time required for the process can be shortened.

  After the completion of the lowering of the prescription bottle 2, after a set time has elapsed (or at the same time as the completion), the supply port 36A of the supply nozzle 36 of the drug solution bottle 23 to be dispensed by rotating the rotary drum 21 is set to the prescription bottle. 2 is located at a position facing the opening 2A.

  After the supply port 36A of the supply nozzle 36 of the drug solution bottle 23 to be dispensed is positioned at the position facing the opening 2A of the prescription bottle 2, in order to position the prescription bottle 2 at the supply position after the set time has elapsed, as described above, Simultaneously with the start of raising the prescription bottle 2, the pump drive motor 40 starts to advance.

  Also in this case, by starting the advancement of the pump drive motor 40 simultaneously with the start of the raising of the prescription bottle 2, the dispensing is compared with the configuration in which the advancement of the pump drive motor 40 is started after the rise of the prescription bottle 2 is completed. There is an advantage that the time required for the process can be shortened.

  After the set time has elapsed since the advancement of the pump drive motor 40 has been completed (or at the same time as the completion), the pump 24 is rotated to feed a predetermined amount of chemical into the prescription bottle 2, and the second time chemical is charged Ends.
