[0012]
The operation of the separation lever 11 will be described with reference to FIGS. FIG. 4 is a side view of the right end portion of FIG. 3 including the separation lever 11. The separation lever 11 is rotatably supported on the cassette 2 by a shaft 14. The position of the rotated separation lever 11 is indicated by a one-dot chain line. The separating lever 11 is given a counterclockwise rotational force by a tension spring 15 and is normally at a position indicated by a solid line in FIG. When the separation lever 11 is in the position of the solid line, the leading injection 7B is held by the stopper 34 fixed to the cassette 2 and the bottom plate 11B of the separation lever 11. FIG. 5 is a side view showing a state in which the take-out unit 9 controlled by a control device (not shown) is positioned at a predetermined position for taking out the injection 7 from the cassette 2 having the desired injection 7. FIG. 6 is a side view showing the operation of taking out the injection 7 from the take-out part 9. FIG. 7 is a side view showing a state in which the take-out operation of the take-out unit 9 is completed. 5, 6, and 7, the cassette 2 is illustrated by reversing the cassette 2 of FIG. 4 from side to side.
[0013]
In FIG. 5, the extraction unit 9 includes a guide shaft 65 and a moving table 20 that moves while being supported by the guide shaft 65. The moving table 20 is attached to a belt 67 extended between two pulleys 66 and 66. The moving table 20 is provided with a lever 21B rotatably supported by a shaft 21A, and a payout roller 21 is provided at the tip thereof. The lever 21B is given a rotational force counterclockwise by a spring 21C. An arm 21D protruding downward is fixed to the lever 21B. An intermediate pocket 22 which is an intermediate receiving member fixed to the moving table 20 is disposed below the arm 21D. The moving table 20 moves in the direction of the arrow 20A due to the counterclockwise rotation of the pulley 66, and reaches the position shown in FIG. In this state, the distal end of the arm 21D hits the metal 9A provided at the lower portion of the take-out portion 9, and the lever 21B rotates clockwise as shown by the solid line in FIG.
[0014]
The position of the lever 21B before rotation is indicated by a one-dot chain line. As the lever 21B rotates, the payout roller 21 pushes the bent portion 11A (FIGS. 3 and 4) of the separating lever 11 downward in the drawing. As a result, as shown in FIG. 4, the separation lever 11 rotates clockwise, and the separation plate 12 pushes the injection 7B downward. When the distance between the lower end 34A of the stopper 34 and the floor surface 11B of the separation lever 11 exceeds the diameter of the injection 7, the leading injection 7B is dropped from the cassette 2. As shown in FIG. 6, the dropped injection 7 </ b> B passes through the separation lever 11, moves with the moving table 20, and rolls down to the intermediate pocket 22 waiting at the lower part of the separation lever 11.
[0015]
Only the first injection 7B is dropped from the cassette 2 by the clockwise rotation of the separation lever 11, and the next injection 7C is held by the separation plate 12 as shown by a one-dot chain line in FIG. So don't fall. After the leading injection 7B falls, the moving table 20 of the take-out part 9 returns to the original position as shown in FIG. As a result, the separation lever 11 returns to the original position by the tension of the tension spring 15 (FIG. 4). The injection 7B that has fallen into the intermediate pocket 22 rolls over the intermediate pocket 22 and falls onto the dispensing door 24 that is arranged further downward. Since flexible cushioning materials 22A and 23 such as sponges are attached to the upper surfaces of the intermediate pocket 22 and the dispensing door 24, the glass ampoule is not damaged when the injection 7 falls. With the return of the separation lever 11, the next injection 7C after the first injection 7B comes to the top position and comes into contact with the stopper 34. When the desired type and number of injections are obtained on the dispensing door 24, the extraction unit 9 is moved to the lower end of the arm 51 and the tray 59 is moved below the arm 51. In this state, as shown by a two-dot chain line in FIG. 7, the dispensing door 24 is opened downward, and the injection 7 is dropped onto the tray 59. Finally, the tray 59 is moved to the vicinity of the extraction window 62 (FIG. 1), and the injection 7 in the tray 59 is taken out.
[0016]
An operation for replenishing the cassette 2 with a new injection 2 when the remaining amount of the injection 7 in the cassette 2 is almost exhausted or a mechanism for facilitating this operation will be described with reference to FIG. .
The perspective views of FIGS. 8A, 8B, and 8C show only the main parts including the pulley 39, the belt 41, and the pusher 10 attached to the belt 41 in FIG. 3 for easy understanding. FIG. 8A shows the position of the pusher 10 in the same state as in FIG. 3 in which a sufficient number of injections 7 are loaded in the cassette 2. In this state, the shuttle 70 is attached to a position of the belt 41 in the vicinity of the pulley 39A. The length of the belt 41 from the shuttle 70 to the pusher 10 measured clockwise and the length of the belt 41 from the shuttle 70 to the pusher 10 measured counterclockwise are substantially equal. The fixed block 71 is fixed to the cell 47 in which the cassette 2 shown in FIG. In FIG. 3, when the injection 7 is taken out by the operation of the separation lever 11, the pusher 10 moves in the direction indicated by the arrow 10D in FIG.
[0017]
(B) of FIG. 8 shows the position of the pusher 10 when the injection 7 is taken out and the injection 7 in the cassette 2 is completely lost or remaining. As a result of the pusher 10 moving to the right, the shuttle 70 moves to the left and comes closer to the fixed block 71. When the cassette 2 is emptied, the shuttle 70 comes into contact with the fixed block 71. When the cassette 2 is pulled out from the cell 47 in the state shown in FIG. 8B, the pulleys 39, 39A and the belt 41 move in the direction of the arrow 2A. Since the fixed block 71 is fixed to the cell 47, it does not move. Therefore, the shuttle 70 is pushed by the fixed block 71 in the direction of the arrow 71A, and rotates the pulley 39 via the belt 41 in the clockwise direction. By the clockwise rotation of the pulley 39, the pusher 10 moves in the direction of the arrow 10A and approaches the pulley 39A. A state in which the cassette 2 is completely pulled out from the cell 47 is shown in FIG. The position of the stopper 10 shown in FIG. 8C is substantially the same as the position shown in FIG. In this state, as shown in FIG. 3, since the gap between the pusher 10 and the stopper 34 is greatly opened, the loading operation of the injection can be performed easily and quickly. When the cassette 2 is returned into the cell 47, the shuttle 70 is separated from the fixed block 71, so that the pusher 10 presses the injection 7 against the stopper 34 by the tension of the Conston spring 13, and the state shown in FIG.
[0018]
【The invention's effect】
As described in detail in the above embodiments, according to the present invention, the ampule of the injection is dropped on the cushion material with a small drop, so that the ampule is practically not damaged. In the conventional apparatus, since the ampoule is gripped by the take-out chuck and taken out, it takes time to move and position the take-out chuck and to adjust the gripping force. However, in the present invention, since the injection is taken out by a simple operation of dropping with a small drop, the time required for taking out is short. Accordingly, the medicine can be taken out quickly, and the dispensing operation of the injection medicine at a hospital or the like can be rationalized and the work efficiency can be improved.
