Provided is an automatic teaching system that is readily able to achieve automation, even when a small but varied number of processing objects are to undergo polishing or coating. The automatic teaching system includes a three-dimensional shape measurement apparatus, a reference marker, an image analysis apparatus, and a robot control device. The three-dimensional shape measurement apparatus acquires shape data of a processing target region on a processing object relative to the reference marker, and the image analysis apparatus divides the shape data of the processing target region into a plurality of continuous reference surfaces, in accordance with a predetermined algorithm, automatically generates a program of an operation path along which a polishing apparatus or coating apparatus of the robot is to be operated, for every reference surface, in accordance with a predetermined operation path generation rule, and transmits the program of the operation path to the robot control device.

The amount of wash water to be consumed in an electrodeposition coating facility and the amount of used wash water to be discharged that requires post-treatment are reduced. To achieve this object, an electrodeposition coating facility that includes a degreasing process section A, a post-degreasing rinse section B, a chemical conversion process section C, a post-chemical-conversion rinse section D, an electrodeposition coating section E, and a post-electrodeposition rinse section F is provided with a filtration process apparatusand a wash water recycling line. The filtration process apparatusperforms a filtration process on wash water W after being used to wash an object to be coatedin the post-electrodeposition rinse section F. The wash water recycling linefeeds, to the post-chemical-conversion rinse section D, the wash water W after being subjected to the filtration process in the filtration process apparatusas wash water W to be used to wash an object to be coated in the post-chemical-conversion rinse section D.

Provided is an automatic polishing system that allows a polishing treatment of an article while circumventing a polishing averting portion of the article. A polisher is attached to a leading end portion of a movable arm of a work robot. A control device controls the work robot and the polisher, based on position information of a polishing target surface of an article, so that the polisher is moved along the polishing target surface by a movement of the work robot while providing a polishing action on the polishing target surface at the same time. An image of the article including an image of an area demarcation marker annexed to the article for demarcating the area of the polishing target surface is captured by a three-dimensional image capturing machine. The control device produces the position information of the polishing target surface by determining the position of the area demarcation marker based on image data of the image.

In a coating pretreatment facility using microbubbles, an arrangement is made to make it possible to form the facility compact and to reduce the initial cost and the running cost of the facility. A preliminary cleansing water supplying passageis provided for supplying cleansing waters W, Wused in cleansing of a coating subject article B in flushing sectionsfollowing a degreasing sectionas preliminary cleansing water Wfor use in preliminary cleansing of the coating subject article B in a preliminary cleansing section. A microbubble generator deviceis provided for causing the preliminary cleansing water Wused in the preliminary cleansing of the coating subject article B in the preliminary cleansing sectionto contain microbubbles.

Coating pretreatment facility

A method of producing a cracker from a raw material such as grain such as unhulled rice, or artificial rice, composite raw material formed in a chip-shape, or the like is disclosed. It comprises steps of compressing and heating for a predetermined time the raw material already processed to some extent to advance and contained within a hermetically closed chamber defined in upper and lower baking molds heated, moving instantaneously the upper mold finely up and down to spread the raw material on a bottom surface of the lower baking mold, and in the foregoing state, compressing and heating the raw material again, and expanding instantaneously the compressed and heated raw material at a time when the upper baking mold starts moving upwardly to remove the compression, thereby shaping the material in a cracker of a desired form in a self-sustaining structure. An apparatus for carrying out the method is also disclosed.
