Abstract:
A paint supply method supplies a paint into a paint cartridge (10) by using a filling valve (1) that has: a paint supply channel (3) that is linkable in communication with a supply portion (11) provided for supplying the paint into the paint cartridge (10); a branch channel (6) that branches from the paint supply channel (3) near a site of linkage in communication between the supply portion (11) and the paint supply channel (3); and a trigger valve (9) as an open-close valve of the paint supply channel (3) which is disposed in the paint supply channel (3) upstream of the site of linkage in communication. After a filling liquid (52) is filled into the branch channel (6), the trigger valve (open-close valve) (9) is opened, and the paint is supplied into the paint cartridge (10) via the paint supply channel (3).
Abstract:
A coating material leakage detection device capable of finding contamination of a hydraulic fluid at an early stage and capable of preventing the degradation of a coating quality of a work. For this purpose, coating material leakage from a coating material chamber 13 to a hydraulic fluid chamber 14 in a coating material cartridge 11 is detected by a coating material leakage detection device 31. The coating material cartridge 11 is attached detachably to a coating material filling device 21, and the coating material chamber 13 and the hydraulic fluid chamber 14 are partitioned from each other by way of a deformable partition body 12. Further, the coating material leakage detection device 31 has a contaminant detection means 33 for detecting the contaminant in the hydraulic fluid attributable to the coating material leakage. Accordingly, contamination of the hydraulic fluid can be found at an early stage.
Abstract:
For providing a coating material cartridge capable of reliably discharging air and coating material stagnated in a hydraulic fluid chamber, a coating material cartridge (l0) has a cartridge main body (11), a partition body (12), a coating material transfer path (17) and a plurality of hydraulic fluid transfer paths (18a, 18b). The partition body (12) partitions the inner region of the cartridge main body (11) into a coating material chamber (13) and a hydraulic fluid chamber (14). Each of the hydraulic fluid transfer paths (18a, 18b) has a plurality of openings that opens in the hydraulic fluid chamber (14) and the distance for each of the openings from the connection end face (11f) is different from each other.
Abstract:
A paint filling apparatus has a plurality of header portions (2), and one common manifold portion (3) that is capable of supplying a cleaning liquid to each header portion (2). One side of each header portion is attachable to and detachable from a paint cartridge (10), and another side of each header portion is attachable to and detachable from the common manifold portion (3). Each header portion (2) has a paint supply channel for filling a paint into the paint cartridge (10). The paint supply channel of each header portion (2) is constructed of a piping member (23) and a paint channel (2b). An end portion of each header portion (2) is linkable in communication with the inside of the paint cartridge (10), and another end portion thereof is linked in communication with a corresponding one of paint tanks (21) that are provided separately for each of the paint colors. An intermediate portion of each paint supply channel is provided with a paint valve (4) that controls the open-closed state of the upstream side of the paint supply channel.
