Abstract
According to an embodiment, a sample processing apparatus includes a detection section configured to detect pose information regarding a sample container which is configured to house a sample; and a raising section which turns the sample container in a predetermined direction based on the pose information regarding the sample container to raise the sample container.
Claims6
A sample processing apparatus comprising:
- a sensor configured to detect pose information regarding a sample container which has a head portion and a bottom portion and is configured to house a sample;
- a carrying mechanism configured to carry the sample container in a lying state;
- a raising mechanism comprising:
- a holding mechanism which has a pair of holding blades disposed to face each other and to be separated from each other, the holding blades configured to hold in between and release the sample container in the lying state, the holding mechanism being rotatable in normal and reverse directions around a rotational axis that extends in a horizontal direction and is defined at a position between the head portion and the bottom portion of the sample container;
- a controller configured to determine a rotation direction of the holding mechanism as either normal or reverse direction, based on the pose information indicating an orientation of the sample container;
- and
- a turning mechanism which turns the holding mechanism in the rotation direction to turn and raise the sample container upright, and at the same time to position the sample container into a uniform orientation with respect to other sample containers, with the bottom portion being located at a lower level than the head portion such that the sample in the sample container contacts the bottom portion of the sample container;
- and
- an insertion mechanism comprising:
- a guide member provided under the holding mechanism, the guide member configured to support a circumference of the upright sample container that falls when the holding blades are released, and thereby to regulate the sample container to move vertically;
- and
- a shaft formed in a part of the wall of the guide member and configured to push the sample container down vertically,
- wherein the insertion mechanism inserts the upright sample container into a holder provided under the holding blades and having an insertion hole that opens in an upper part of the holder.

A sample processing method comprising:
- carrying a sample container in a lying state along a predetermined carrying path, the sample container having a head portion and a bottom portion and being configured to house a sample;
- detecting pose information indicating an orientation of the sample container by a sensor;
- determining by a controller a rotation direction as either normal or reverse direction based on the pose information so that the sample container is raised upright with the bottom portion of the sample container being located lower than the head portion;
- turning a turning mechanism configured to turn the sample container that is in the lying state, into the rotation direction around a rotational axis that extends in a horizontal direction and is defined by a position between the head portion and the bottom portion of the sample container so that the sample container is raised upright such that the sample in the sample container contacts the bottom portion of the sample container, wherein the turning mechanism comprises a holding mechanism which has a pair of holding blades disposed to face each other and to be separated from each other, the holding blades configured to hold in between and release the sample container in the lying state, and the holding mechanism is rotatable in normal and reverse directions around a rotational axis that extends in a horizontal direction and is defined at a position between the head portion and the bottom portion of the sample container;
- and
- inserting the sample container into a holder provided under the holding blades and having an insertion hole in an upper part of the holder, by releasing the holding blades, allowing the sample container in an upright state to fall into a guide member provided on the holding mechanism, the guide member to support the outer circumference of the upright sample container, and pushing the sample container down by a shaft configured to push the sample down into a holder.
