ROBOT HAND FOR AUTOMATIC INDUSTRIAL ANALYSIS OF COAL OR THE LIKE

摘要

PURPOSE:To automate respective operations according to the sequence necessary for analysis of coal or the like by providing two stoppers which project apart from each other in the longitudinal direction on the inside of the top end of hands for gripping analytical vessels, hollow grooves intersecting orthogonally with the longitudinal direction to the intermediate position of stoppers and providing a knob which projects to the outside of one hand. CONSTITUTION:Two pairs of the stoppers 6 and hollow grooves 7 are provided to the inside of the robot hands 3. These hands grip the moisture, ash content and volatile matter vessels 9-11 by each piece, move the vessels, remove caps 11' by utilizing the grooves 7, hold a spoon 13, charge a sample from a sample vessel into the vessels 9-11, place the vessels on trays 18, 20, 22 after weighing, engage the knobs 8 of the hands 3 into the end holes and push respectively the vessels into electric furnaces 19, 21, 22 for the ash content, volatile matter and moisture. The vessels are discharged from the furnaces 19, 21, 22 by means of the knobs 8 in the same manner as mentioned above after the prescribed heat treatments and the ash content, volatile matter and moisture are measured.
