An airflow detection apparatus () includes an airflow detection apparatus () that detects an airflow in a painting booth, and includes a thread-like member () installed inside the painting booth, an image capture device () capable of generating image data obtained by capturing an image of the thread-like member (), and a calculation device capable of performing calculation processing on the image data. The thread-like member () is installed in the painting booth in a mode in which at least a portion thereof is suspended. The calculation device specifies a portion corresponding to the thread-like member () in the image data, and detects an airflow based on a position of the portion.

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.

Electrodeposition coating facility

The facility includes a first connection mechanism connecting a filter unit to a floor discharging section to establish communication between an opening portion of the floor discharging section and an upper face opening portion of the filter unit and a second connection mechanism connecting the filter unit to an exhausting chamber to establish communication between an opening portion of the exhausting chamber and a side face opening portion of the filter unit. The first connection mechanism includes a seal portion that comes into contact with an entire circumference of an outer face of an upper end portion of the filter unit, thus preventing leakage of exhaust gas. The seal portion includes an introducing portion for introducing the upper end portion of the filter unit to the seal portion from a horizontal direction.

Painting facility

A paint drying device where leakage of air between a drying chamber and a driving section accommodating chamber is prevented reliably. In the paint drying device in which the drying chamber and the driving section accommodating chamber communicate with each other via a through hole through which a power transmission tool extends, there are provided an air feeding passage for feeding air present outside the drying chamber to the driving section accommodating chamber by an air feeding fan and an exhaust passage for discharging air in the driving section accommodating chamber to the outside of the drying chamber by an exhaust fan. An air amount adjustment device is provided for adjusting a ratio between an amount of air to be fed to the driving section accommodating chamber via the air feeding passage and an amount of air to be discharged from the driving section accommodating chamber via the exhaust passage.

Paint drying device

A work facility that is capable of adjusting an air volume without a work defect and saving energy. The opening degree of an air volume adjusting damper corresponding to a filter booth for which the individual air volume measured by a corresponding individual flowmeter is the smallest among the respective individual air volumes for the filter booths is adjusted to a completely open state, whereas the opening degree of any other air volume adjusting damper is adjusted to such an opening degree that the individual air volume for the corresponding filter booth as measured by a corresponding individual flowmeter is equal to the smallest individual air volume, and a gas discharge fan is adjusted by a total air volume adjusting mechanism so that a total air volume measured by a total flowmeter is equal to a predetermined target total air volume.

Work facility

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

The invention relates to a system for treating a surface of an article with a liquid material by dipping. This system includes (a) a major tank having therein the liquid material for dipping the article thereinto; and (b) a circulatory mechanism for circulating the liquid material through the major tank. The circulatory mechanism is arranged to make a flow of the liquid material through the major tank such that the majority of the flow is in one direction that is substantially along the longitudinal direction of the major tank. Thus, contaminants and/or bubbles are not distributed over the entire major tank, but are effectively promptly removed from the major tank. The flow of the liquid material may include a first flow of the liquid material in the major tank and a second flow that is lower than the first flow in position. The first and second flows run substantially in parallel with each other, before the first and second flows reach a downstream end thereof in the major tank. The major tank may be formed at the downstream end with a wall having a special configuration such that the first and second flows separate or diverge from each other at the downstream end, and thus the flow of the liquid material through the major tank becomes very smooth.
