Title:
CARRYING MECHANISM IN CONTINUOUS TREATING APPARATUS
Document Type and Number:
Japanese Patent JP3218840
Kind Code:
B2
Abstract:
PURPOSE: To make the separating state of a material to be treated in each of treating chambers good and to improve the treating accuracy and the treating efficiency by laying the material to be treated on a spacer and shifting it with carrying mechanism of a specific structure, at the time of continuously treating the material to be treated in plural treating chambers.
CONSTITUTION: The material W to be treated is carried out from a take-out hole 51 after sintering it through a preparing chamber 4, degreasing chamber 2, sintering chamber 3 and cooling chamber 5. The material W to be treated enters the preparing chamber 4 from a carry-in hole 41 and laid on a tray 82 through a spacer 81 on a furnace hearth 42. Heat insulating plates 43, 61, 62, 71 and partition plates 64, 73 in each of the chambers are pulled up, and a spacer 81 is turned by 90° with a motor 84 to bridge respective furnace hearths 42, 22, 32, 52. The tray 82 is stopped and only the spacer 81 is shifted and the material W to be treated on the spacer is shifted in each of chambers 4, 2, 3, 5 in order and sintered. The heat insulating plates and the partition plates between respective chambers are descended with cylinders 44, 63, 72 during operation to perfectly separate respective chambers from each other, and the temp. and the pressure in the adjacent chambers are kept so as to prevent the mutual intrusion and mutual interference of gas atmosphere, and the treating accuracy and the treating efficiency in each treating chamber are improved.
