Abstract
A sample autoloader loads a sample into a furnace and removes a sample from the furnace. The sample autoloader includes a sealing plate for sealing the furnace. The sample autoloader also includes a mechanism for pushing a sample into the furnace and removing a sample from the furnace. The sample autoloader may include a hotel which stores sample containers for automatic loading and a container which receives spent sample containers.
Claims21
An automatic sample loader for use with an analytical combustion furnace having a horizontal combustion tube comprising:
- a first frame member comprising a first horizontal plate vertically separated from a second horizontal plate by a plurality of vertical column members;
- a guide rail mounted on said first horizontal plate;
- a first carriage member movably mounted on said guide rail;
- a hotel member removably mounted on said carriage member, said hotel member comprising a frame having a top and a bottom member vertically spaced by attached end members with a plurality of vertically spaced horizontal plates connected at each end to said end members for carrying a plurality of combustion tools;
- motor means for moving said carriage member;
- a second frame member attached to and vertically spaced above said first frame member;
- a pair of horizontally spaced vertical end plates on said second frame member with one of said end plates having an aperture therein;
- a pair of spaced horizontal guide rods supported by said end plates;
- a second carriage member movably supported on said guide rods, said second carriage member comprising a furnace seal member having an aperture therein and a guide member spaced from said furnace seal member;
- a rotary actuator support member on said guide rods, and a rotary actuator member carried on said rotary actuator support member;
- a motor on said second carriage member for reversibly moving said rotary actuator support member;
- a boat retrieval rod supported by said rotary actuator member, said boat retrieval rod extending through said furnace seal member, a hook member on the distal end of said boat retrieval rod, said rotary actuator member for reversibly rotating said boat retrieval rod and hook member from a first position where said hook member extends horizontally to a second position where said hook member extends downwardly;
- a first vertical guide rail mounted on one side of said first carriage member;
- a first actuator member movably supported on said first vertical guide rail, said actuator member comprising a pneumatic cylinder having a horizontally extendible rod member for pushing combustion boats from said hotel member;
- motor means for reversibly vertically moving said first actuator member on said first vertical guide rail;
- a second vertical guide rail mounted on the other side of said first carriage member;
- and
- an elevator means movably mounted on said second vertical guide rail for receiving combustion boats from said hotel member and for delivering said combustion boats to a position where said combustion boats can be pushed by said boat retrieval rod.

- a frame member for attachment to the horizontal combustion furnace comprising
- a first end plate having an aperture therein,
- a second end plate spaced from said first end plate, and
- a pair of spaced parallel guide rods joining said first and second end plates together;
- a furnace seal member having an aperture therein movably supported on said spaced guide rods;
- a closure member for said furnace seal member;
- reversible means for moving said furnace seal member into a sealing position and for moving said moving said seal member away from said said sealing position;
- a carriage member movably supported on said guide rods;
- a rotary actuator on said carriage member;
- a boat retrieval rod operatively connected to said rotary actuator and extending through said closure member in said furnace seal member, said boat retrieval rod having a hook on the end thereof remote from said rotary actuator, said rotary actuator reversibly moving said hook on said boat retrieval rod from an inoperative to an operative position;
- and
- a motor mounted on said frame for reversibly moving said carriage member.
