Description of the Related Art In order to analyze blood and other liquids to be tested and to carry out tests and measurements for diagnosing disease states from the components contained in the liquids, first, pull out a rubber stopper or the like that seals the opening of the test tube. After that, it is necessary to sort the liquid under test in the test tube according to the contents of inspection and measurement and supply it to the analyzer.
This unplugging is progressing from conventional manual work to automation, and as shown in Utility Model Publication No. 2-13080, a structure has been devised in which an air cylinder is used to pinch the plugs and alternately pull them up. . According to this method, in order to prevent the liquid inside the test tube from splashing due to shock etc. when the stopper is removed, it is configured to connect in series cylinders with a two-stage stroke of different strength and weakness. Structural complexity is inevitable.

栓抜き機を提供するにある。In the method of alternately twisting and lifting the stopper as described above, since the stopper acts slightly at a right angle to the circumference of the test tube at the moment when the stopper separates from the test tube, the inside of the test tube is vacuumed or applied. It is inevitable that the liquid and vaporized gas inside will scatter into the atmosphere unless it is done very slowly while being pressurized. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a cap opener having a simpler structure, which reduces shock splattering as much as possible.

与えて栓抜きを行うようにしたものである。The present invention has taken the following means in order to achieve the above object. That is, in a cap opener that automatically removes a plug from a test tube by operating the test tube and the plug separately, a cylinder mechanism is used for both ends of a cap opening arm having a pair of plug holding jigs. When the pulling operation is performed, the stopper pressing jig is rotated to remove the stopper.

開栓が行えるのである。開栓後の状態を図４に示す。There is a test tube 2 with a stopper 1, which is fixed by test tube retainers 3, 3 '. A plurality of test tubes 2 are set in separate test tube holders (not shown), and are movable by a belt conveyor or the like (not shown). On the other hand, the fixed end 4 has cylinders 5 and 5 ', and the tips of the cylinders 5 and 5'are fixed to a ring-shaped bearing guide 6. The bearing guide 6 is provided with a fixing metal fitting 8 inside via a ball bearing 7, and is configured to be rotatable inside the bearing guide 6. Further, the stopper fittings 9 and 9'are attached to the fixing fitting 8, and the levers 1 and 9 with the rollers 10 and 10 'are attached to the stopper removing arms 9 and 9'.
1, 1'and are held at fulcrums 12, 12 'Spring 1
3 are arranged so as to attract each other. The other end of this lever is formed in a claw shape for pressing the stopper 1. In addition, the rollers 14, 1 are attached to one end of the bottle opener arms 9, 9 '.
There is a 4 ', and the tilt guides 15 and 15' are pulled by a pulling spring 16. Further, the fixing bracket 8 has a cylinder 1
7 is provided, and the tapered rod 18 is directly connected. In the above condition, when the test tube 2 with the stopper 1 comes under this unit and the cylinders 5 and 5'are operated by the operation of the controller (not shown), the stopper opening holder 6 becomes integrated. Can be pushed down. When the cylinder 17 is further actuated in this state, the rollers 10 and 10 'are spread out, and the claws of the levers 11 and 11' are actuated in the direction of narrowing around the fulcrums 12 and 12 ', and the stopper 1 is sandwiched by the claws. This state is shown in FIG. Next, the cylinders 5 and 5'are pulled up, but if they are pulled straight up, the stopper 1 is in close contact with the test tube 2 and the friction does not come out so much that the stopper 1 is torn or the claw comes off. . Therefore, according to the present invention, when the cylinders 5 and 5'are raised, the stopper arms 9 and 9 are rotated so as to rotate along the inclined guides 15 and 15 '.
9'is pressed by a tension spring 16, and the fixing metal fitting 8
Is equipped with a ball bearing so that it can rotate. Therefore, when the cylinders 5 and 5'are actuated and pulled upward, a rotational force is applied to the stopper 1 along the inclined guides 15 and 15 ', so that the stopper 1 can be pulled upward while rotating and opened. The state after opening the cap is shown in FIG.

５′は速度調節用に強弱２段階の必要はない。As described above, when the cap is opened, it is pulled up while rotating, so at the moment of opening, a slight amount of air flow from the circumferential direction is injected, and the cylinder 5,
5'is not required to have two stages of strength and weakness for speed adjustment.

果が著しい。According to the present invention, the stoppers of the test tubes can be pulled out automatically and surely, and a large number of them can be removed at a time in a good working environment without worrying about the adherence of the liquid to be tested as in the conventional manual work. It can be applied to an automated device that removes the stopper, and the effect of safety and labor saving is remarkable.
