This example was used for a sterility test device for powdered sample vials, and the above-mentioned sample vial was supported in an upright state in a vial case and transported by an automatic transport device to the solution filling and dissolving device according to the present invention. It is designed to stop at the location where the solution filling/dissolving device is installed.

As shown in FIGS. 1 and 2, the solution filling/dissolving device has a motor 6 installed on the top surface of a base 5, and serves as a support at the top end of an upward shaft 7 that is moved up and down by the motor 6. A head 8 for filling and swinging the solution solution is fixed. A swinging cylinder 9 is mounted horizontally on the head 8, and a shaft 1 connected to the piston rod of the cylinder 9 is mounted on the head 8 in a horizontal direction.
The rack 11 is fixed at 0. On the other hand, a swinging case 12 is rotatably attached to the solution filling/swinging head 8 via a rotating shaft 13, and a pinion 14 that meshes with the rack 11 is fixed to the rotating shaft 13, thereby forming a swinging cylinder. 9 rotates the pinion 14 and the rotating shaft 13 forward and backward, and the swinging case 12 fixed to the rotating shaft 13 is reciprocated in an arc around the rotating shaft 13 as a fulcrum, that is, swings. That's what I do. This swing angle is preferably 90° or more, preferably in the range of 110 to tSO°, and particularly optimally around 120°.

The swinging case 12 has a pair of gripping pieces 14A, 141.
The swinging hand 15 consisting of
A and 14B are opened and closed to detachably hold a container I consisting of a powder sample vial. Further, a solution filling needle holder 18 is attached to the swinging case 12 via an elevating mechanism 17 such as a cylinder.
8 holds the solution filling needle 19 in a vertical position.

A tube 21 for supplying the solution from a solution supply device 20 shown in FIG. 3 is connected to the upper part of the solution filling needle 19. In the solution supply device 20, a rotary table 2 is connected to a shaft 24 which is rotationally driven by a motor 23 installed on a base 22.
5 is attached, and a plurality of solution bottles 26 filled with solution are fixed to the rotating table 25 in an inverted state. The solution bottle 2
A suction needle 27 connected to the other end of the tube 21 is raised and inserted into the lower end rubber stopper 26a of the tube 6 by an elevating device 28 when filling the solution. The tube 2
1 is set in the solution filling pump 29 as shown in the figure and extends toward the solution filling/swinging device, and the solution filling needle 19 connected to the tip is held by the holder 18 so as to be connected in a stacked manner. There is.

The solution filling/swinging device described above includes a transport device 32 that automatically transports a case 31 holding a powder sample vial 30 (hereinafter abbreviated as powder injection container) in an upright state into which powder B is injected at the front side. It was installed at a side position, and when the case 31 reached the installation position, it automatically stopped, and the solution filling/swinging device filled the powder pouring container 30 with solution A, dissolved it, and returned it to the case 31. Afterwards, it is automatically transported to the next process by a transport device 32.

Next, the operation of the apparatus according to the present invention will be explained. When the powder injection container 30 is conveyed and stopped, the solution needle 27 rises and is inserted into the rubber stopper 26a of the solution bottle 26, and the powder injection container 30 is removed by the gripping pieces 14A and 14r3 of the swinging hand 15. Grasp the opening and insert the solution filling needle 19 into the stopper 11 of the powder injection container 30. Next, the solution filling pump 29 is rotated to fill the powder pouring container 30 with the solution. After filling a predetermined amount of Ii1, the solution filling needle 19 is raised and removed from the rubber stopper of the powder injection container 30.

After filling the solution solution in this way, the solution solution filling/swing head 8 is raised by the motor 6, and then the piston of the swing cylinder 9 is pushed out, and the rack 11 is advanced via the shaft IO and the pinion 14 Rotate counterclockwise. The rotation of the binion 14 also rotates the swinging case 12 via the rotating shaft 13, and the gripping piece +4A of the swinging hand I5,
14I3, hold the powder injection container 30 in an upward direction 1W (
X), move in an arc shape and raise to the upper position (Y). At this time, as shown in FIG. 4, the powder pouring container 30 changes from an upward vertical position to a sideways horizontal position, at an angle of more than 90 degrees! Since it rotates up to about 20 degrees, it is slightly tilted downward at the tip position. Then, when the piston of the swinging cylinder 9 is pulled, it moves in the opposite direction, that is, to the upper position or the lower position, in an arc shape, and repeats this rotational reciprocating movement a required number of times. In the upper bound process of the above circular arc swing, the capacity
Powder B that had accumulated in the lower corner of rj, 30 flows and melts as shown by the arrow in the figure, and in the descending process, powder B that had accumulated in the opposite corner flows in the direction of the arrow and dissolves. By repeating this, the powder B that had accumulated in the corners is completely dissolved in the solution A. The larger the swinging angle of the container 30 and the faster the swinging speed, the faster the flow of the dissolving liquid A occurs, and the more turbulent flow occurs, the more rapidly the powder A that has accumulated in the corners is dissolved. In addition, the rocking speed is 70
If it is reciprocated per minute or more, even powders that are difficult to dissolve will be dissolved.

After dissolving the powder, the motor 6 lowers the solution filling/swinging head 8, returns the powder-poured and dissolved container to the case 31, opens the gripping pieces 14A and 1413 of the swinging hand 15 to release the grip, and removes the case. Return to 31. Next, the motor 6 raises the solution filling/oscillating head 8 to complete the solution filling/oscillating dissolution process.

The present invention is not limited to the above-mentioned embodiment, and the swinging case 12 may be rocked using an appropriate drive mechanism such as a reversible rotary motor other than the drive mechanism consisting of a combination of a rack and a pinion. Furthermore, it goes without saying that the present device can be employed in any appropriate device other than the sterility testing device for powdered sample vials.

Effects of the Invention As is clear from the above explanation, according to the apparatus of the present invention, the operation of dissolving the powder by filling the container into which the powder has been previously injected with the dissolving solution can be performed automatically without any manual intervention. It can be done. Further, according to the present device, since a turbulent flow is generated that is optimal for not dissolving the powder that has accumulated in the corners of the container, it is possible to efficiently dissolve the powder.

In particular, when this device is used for sterility testing of powdered sample vials, it has the unique effect of preventing human contamination due to automation and no human intervention.
