Abstract

The medicament dispensing machine enables to use vials having various sizes and shapes without changing a part in the machine or without performing a special operation. The medicament dispensing machine contains a discharging unit that receives a vial filled with a medicament from a medicament filling means and discharges out of a vial discharging window. The discharging unit contains a vial gripping means having a pair of gripping arms that grip a vial, a body of gripping means having the vial gripping means, a moving means that moves the vial gripping means from the medicament filling means to the vial discharging window, and an orientation changing mechanism that changes the orientation of the body of gripping means. With a coordination of the movement of the body of gripping means toward the vial discharging window, the orientation changing mechanism makes the gripping arms orient to the vial discharging window.

a vial gripping device for receiving and gripping the vial, the vial gripping device comprising a pair of gripping arms,

a body of gripping device comprising the vial gripping device,

a moving mechanism for moving the vial gripping device from a place where the vial gripping device receives the vial to a place where the vial discharging window is located, and

an orientation changing mechanism for changing an orientation of the body of gripping device;

wherein the pair of gripping arms comprising;

a vial detection device for detecting the contact of at least one of the gripping arms to the vial, the vial detection device provided in the contact portion of at least one of the gripping arms;

wherein the vial is transferred to the gripping arms from the medicament filling device with a confirmation of detection by the vial detection device that the gripping arms have gripped the vial,

wherein the orientation changing mechanism changes the orientation of the body of gripping device so that the gripping arms face in a direction of the vial discharging window after the vial detection device confirms the detection that the gripping arms have gripped the vial.

2. The medicament dispensing machine of claim 1, further comprising:

a label pasting device for pasting a label on a body of the vial; and

rotating members provided at ends of the gripping arms and supported by the gripping arms so that the rotating members freely rotate while in contact with the body of the vial;

wherein the vial gripping device receives the vial on which the label is pasted by the label pasting device; and

wherein the vial gripping device discharges the vial out of the vial discharging window.

3. The medicament dispensing machine of claim 1, further comprising a transporting unit for transferring the vial from the medicament filling device to the discharging unit;

wherein the transporting unit moves toward and faces the discharging unit, and the transporting unit transfers the vial to the discharging unit; and

wherein upon transferring the vial to the discharging unit, if the vial detection device does not detect the contact of the vial to the gripping arms, the transporting unit further moves the vial toward the discharging unit.

4. The medicament dispensing machine of claim 1, wherein the vial discharging window opens with a coordination of the movement of the body of gripping device towards the vial discharging window.

5. The medicament dispensing machine of claim 1, wherein if the vial is removed from the gripping arms projecting out of the vial discharging window, the moving mechanism moves the vial gripping device to an inside of the body of the medicament dispensing machine, and the vial discharging window is closed.

6. The medicament dispensing machine of claim 1, wherein the discharging unit comprising a pair of guides provided along a discharge route from a side of the medicament filling device to a side of the vial discharging window, the guides placed so that each guide is distant from each other in a horizontal direction;

wherein the body of gripping device is placed between the pair of guides, and the body of gripping device is configured to transfer the vial in a condition in which the body of gripping device is in contact with the pair of guides.

7. The medicament dispensing machine of claim 1, further comprising a first engaging member and a second engaging member that can engage with each other;

wherein the first engaging member is provided on the body of gripping device; and

wherein the second engaging member engages with the first engaging member when the body of gripping device arrives at a position where the vial is transferred to the vial gripping device.

8. The medicament dispensing machine of claim 1, wherein the pair of gripping arms is capable of gripping a vial whose body has a polygonal cross-sectional shape;

and

wherein at least one of the gripping arms comprises a bent portion in which the bent fits to a corner portion of the body of the vial.

9. The medicament dispensing machine of claim 1, wherein the pair of gripping arms is capable of gripping a vial whose body has a polygonal cross-sectional shape;

and

wherein at least one of the gripping arms comprises a gripping piece whose posture follows a side of the body of the vial.

10. The medicament dispensing machine of claim 1, further comprising a transporting unit for transferring the vial from the medicament filling device to the discharging unit;

wherein the transporting unit comprises a pair of transporting arms, which is capable of gripping a vial whose body has a polygonal cross-sectional shape; and

wherein at least one of the transporting arms has a bent portion that fits to a corner portion of the body of the vial.

11. The medicament dispensing machine of claim 1, wherein the gripping arms face in a direction of the medicament filling device when the gripping arms receive the vial;

wherein the gripping arms change an orientation while the gripping arms are gripping the vial and transporting the vial to the vial discharging window; and

wherein the gripping arms face the vial discharging window when the gripping arms reaches the vial discharging window.

12. The medicament dispensing machine of claim 1, further comprising other arms, which transport the vial from the medicament filling device to the gripping arms of the vial gripping device;

wherein the other arms move the vial in a direction toward the gripping arms of the vial gripping device until the medicament dispensing machine detects that the gripping arms of the vial gripping device are in contact with the vial;

wherein the other arms release the vial after the medicament dispensing machine has detected that the gripping arms of the vial gripping device are in contact with the vial; and

wherein the discharging unit initiates the transportation of the vial after the other arms release the vial.

13. The medicament dispensing machine of claim 1, wherein the vial discharging window opens when the gripping arms are approaching or have approached to the vial discharging window;

wherein at least parts of the gripping arms go out of the vial discharging window after the vial discharging window has opened;

wherein the at least parts of the gripping arms go back behind the vial discharging window after the medicament dispensing machine detects that the vial has been detached from the gripping arms; and

wherein the vial discharging window closes when or after the at least parts of the gripping arms go or have gone back behind the vial discharging window.

14. The medicament dispensing machine of claim 1, the discharging unit further comprising a motor, which changes a position of the gripping arms between the medicament filling device and the vial discharging window and which changes an orientation of the gripping arms between a direction of the medicament filling device and a direction of the vial discharging window.
