Sample heating device
A sample heating device includes: a rail-shaped disposal rail extending in one direction in a horizontal plane so that sample boats after heating are arranged and placed in a straight line; a disposal tray that houses the sample boat pushed-out from one end of the disposal rail; a sample boat conveying portion that places the sample boat after the heating at a predetermined placing position on the disposal rail; and a sample boat push-out portion that is positioned closer to the other end side of the disposal rail than the placing position when the sample boat is placed on the disposal rail and that is displaced toward the one end side of the disposal rail after the sample boat is placed at the placing position to slide the sample boats on the disposal rail toward the one end side.
1. A sample heating device comprising:
a heating furnace that includes a space for housing a sample boat holding a sample to be heated and heats the sample held in the sample boat inserted into the space;
a rail-shaped disposal rail extending in one direction in a horizontal plane so that sample boats after heating in the heating furnace are arranged and placed in a straight line;
a disposal tray that is provided on one end side of the disposal rail and houses the sample boat pushed-out from one end of the disposal rail;
a sample boat conveying portion that holds the sample boat after the heating in the heating furnace and places the sample boat at a placing position set at a position on the disposal rail at a distance longer than or equal to a length of the sample boat from the one end; and
a sample boat push-out portion that is positioned closer to the other end side of the disposal rail than the placing position when the sample boat is placed on the disposal rail by the sample boat conveying portion and that is displaced on the disposal rail toward the one end side of the disposal rail after the sample boat is placed at the placing position to thereby slide the sample boats on the disposal rail toward the one end side.
2. The sample heating device according to claim 1 further comprising a moving mechanism that moves the disposal rail in the one direction,
wherein a position of the sample boat push-out portion is fixed and the sample boat push-out portion is displaced on the disposal rail as a result of movement of the disposal rail in the one direction by the moving mechanism.
3. The sample heating device according to claim 2 , wherein the moving mechanism is formed to move the disposal rail in the one direction between a position for placement where the placing position is positioned closer to the one end side of the disposal rail than the sample boat push-out portion and a position for disposal where the placing position is positioned closer to the other end side of the disposal rail than the sample boat push-out portion.
4. The sample heating device according to claim 3 , wherein the sample boat conveying portion is formed to place the sample boat after the heating in the heating furnace when the disposal rail comes to the position for placement.
5. The sample heating device according to claim 4 , wherein the position for disposal is reached when the disposal rail moves by a distance corresponding to one sample boat toward the other end side of the disposal rail from a position where the sample boat push-out portion comes in contact with the sample boat for the first time after the sample boat is placed at the placing position.
6. The sample heating device according to claim 2 further comprising a sample boat rack on which the sample boat before the heating in the heating furnace is placed,
wherein the sample boat rack is formed to be moved in the one direction together with the disposal rail by the moving mechanism.
7. The sample heating device according to claim 1 , wherein identification information that remains recognizable after the heating in the heating furnace is attached to an outer face of the sample boat.
