Spray booth with undeposited coating material collection system

A system for applying a coating material to articles, comprising a booth having a floor, dispensing means for depositing coating material onto the articles in the booth, undeposited coating material falling by gravity to the floor, and sweeping means for collecting the undeposited coating material which has fallen to the floor, the sweeping means including at least one arm, mounting means for rotatably positioning the arm in proximity to the floor, driving means for rotating the arm in a circular path, a collection opening in the floor at least in proximity to the periphery of the circular path, the arm providing means for sweeping the floor in the circular path to collect the undeposited coating material on the floor as the arm is rotated, the material which is collected being moved toward the periphery of the circular path and into the collection opening in response to rotation of the arm.

A system for applying a coating material to articles, comprising a booth having a floor and walls, dispensing means for depositing coating material onto the articles in the booth, the floor including a collection opening for collecting undeposited coating material which falls to the floor, a vent opening in one of the walls, an exhaust system coupled to the vent opening for pulling atmosphere from the booth, at least one filter positioned between the dispensing means and the vent opening for collecting undeposited coating material entrained in the atmosphere being pulled from the booth, and sweeping means for sweeping undeposited coating material on the floor into the collection opening.

A system for applying a coating material to articles, comprising a booth having a floor, dispensing means for depositing coating materials onto the articles in the booth, undeposited coating material falling by gravity to the floor, and sweeping means for collecting material accumulated on the floor, the sweeping means including at least one rotatable arm, mounting means for positioning the arm in proximity to the floor, driving means for rotating the arm so that it sweeps a defined surface area of the floor, a material collection opening in the floor at least in proximity to the periphery of the defined surface area, the arm providing means for wiping the defined surface area to collect the material as the arm is rotated, the material being moved along the arm toward the periphery of the defined surface area and into the collection opening in response to rotation of the arm.

A system for applying a coating material to articles, comprising a booth having a floor, dispensing means for depositing coated material onto the articles in the booth, undeposited coating material falling by gravity to the floor, and sweeping means for collecting the undeposited coating material which has fallen to the floor, the sweeping means including at least one rotatable arm having an elongated tubular section and a plate connected to the distal end of the tubular section, means for rotatably mounting the arm in proximity to the floor so that at least one side of the tubular section forms an acute angle with respect to the floor, the plate forming an obtuse angle with respect to the tubular section and an acute angle with respect to the floor, driving means for rotating the arm so that it sweeps a defined surface area of the floor, a material collection opening in the floor at least in proximity to the periphery of the defined surface area, and at least one flexible blade connected to the tubular section and plate of the arm, the blade having a sufficient width for it to engage and wipe the defined surface area in response to rotation of the arm so that the material is moved along the arm toward the periphery of the defined surface area and into the collection opening.
