A transport device includes a transporting belt capable of transporting a medium, a cleaning unit capable of cleaning the transporting belt with liquid, and a sound collecting unit configured to collect a sound generated by operation of the cleaning unit.

A cleaning device for a residue contaminated conveyor belt includes a roller arranged below the conveyor belt such that the lateral surface thereof contacts a lower strand of the conveyor belt, and a cleaning belt is arranged below the roller. The lateral surface of the roller contacts an upper strand of the cleaning belt, which is tilted relative to a main conveying direction at the upper strand relative to a longitudinal roller axis. A dispensing device on and/or above the cleaning belt feeds a solvent thereon. The dispensing device and the cleaning belt are relatively arranged such that the solvent from the cleaning belt is conveyed by a conveying movement of the cleaning belt into a region in which the cleaning belt contacts the roller, which via a rotational movement, at least partially picks up the solvent located on the cleaning belt and dispenses it onto the conveyor belt.

The present invention relates to a withdrawal plate suitable for an apparatus for withdrawing a sprayed paint to solve a failure of a painting facility and a contamination problem due to paint sludge, which includes: a square frame constituted by left and right side frames 91, an upper frame 92, and a base frame 93; and slats 94 arranged at a predetermined interval within the square frame, in which the left and right side frames 91 facing each other are included in one direction, and the slat 94 is fixed the left and right side frames 91 in an oblique state so that a front is lifted up and moves down backwards when viewed from the side, and multiple slats are consecutively arranged at a predetermined interval in a vertical direction.

A paint recovery and cleaning trolley is provided for an apparatus for applying paint provided with a belt for conveying pieces to be painted. The conveyor belt has an upper outward section and a lower return section. The trolley includes a paint recovery subunit and a cleaning subunit. Each subunit includes a reverse roller in contact with the lower return section of the conveyor belt, a doctor blade tangentially placed with respect to the reverse roller for all its length, and a doctor blade scraping the lower return section of the conveyor belt. In each subunit the respective reverse roller, doctor blades and return section of the conveyor belt form a closed chamber having the shape of a triangular prism, of which the components represent the rectangular faces and that contains a solvent which drips from the triangular faces into a respective collecting hopper. Three positions of the trolley are provided including two inserted positions in which the trolley is totally inserted under the conveyor belt and may be inactive or in operation and a lateral extracted position in which the trolley is totally extracted from the apparatus for applying paint.

A self-cleaning ring conveyor includes a first roller having a first rotational axis and a second roller having a second rotational axis that is parallel with the first rotational axis. The conveyor also includes a first ring extending around a combination of the first roller and the second roller and a second ring extending around the combination of the first roller and the second roller. The first ring and the second ring are parallel to each other. The conveyor also includes a first scraper having a first scraping slot and a second scraping slot. The first ring extends through the first scraping slot and the second ring extends through the second scraping slot.
