According to the paint supply system of the present invention, the paint is packed in a cartridge and not supplied by a pipe, so that a large number of pipes required for the supply by the pipe are provided. This eliminates the need for space, and the size of the space provided for the installation of paint supply equipment beside the booth can be reduced as compared with the conventional case. In addition, since the toner is packed in a cartridge and transported by the transport device, the transport device only needs to have two systems, supply and recovery, regardless of the number of coating colors, which is twice as many as the increased number of coating colors required for paint supply by piping. There is no increase in the number of pipes, and it is possible to flexibly cope with an increase in paint color. In addition, the transfer of the paint from the preparation room to the coating booth can be automated by setting the transfer equipment of the cartridge to automatic transfer.
According to the paint supply system of the second aspect, since the intermediate stocker capable of storing the cartridge is provided near the coating device, the cartridge of the subsequent coating color is transported to the intermediate stocker in advance from the mixing chamber during the coating. Therefore, the paint transport time can be shortened as compared with the case where the cartridge is transported from the preparation chamber to the coating apparatus every time. According to the paint supply system of the third aspect, since the cartridge paint supply device for supplying the paint to the cartridge is provided in the blending chamber, the paint can be packed into the cartridge in the blending chamber. According to the paint supply system of the fourth aspect, the dispensing room is provided with a stocker for storing paint cans delivered from a paint maker and / or a stocker for storing cartridges filled with paint and empty cartridges. In addition, it is not necessary to increase the capacity of the paint can stocker in the coating apparatus or its vicinity or the intermediate stocker, and the size of the space provided for the installation of the paint supply equipment on the side of the booth can be reduced as compared with the related art. Claim 5
According to the paint supply system of (1), since the transfer device has rails serving as a transfer route of the cartridge, the transfer device need only have two rails of supply and recovery regardless of the number of paint colors, and the transfer device can be installed. Space can be reduced, and it is possible to flexibly cope with an increase in coating color. According to the paint supply system of claim 6, the paint supply system has a detection device for detecting information on the object to be coated, and a transmission path for transmitting the information on the object to be coated detected by the detection device to the preparation room. Therefore, the cartridge of the next coating color can be transported to the intermediate stocker before coating, and the coating time can be reduced. According to the paint supply system of the seventh aspect, since there are a plurality of paint supply systems selected according to the production ratio of each paint color, the most suitable paint supply system is selected according to the production ratio of each paint color. As a result, paint supply efficiency and productivity can be improved. According to the paint supply system of the eighth aspect, the most suitable paint supply system can be selected from the three paint supply systems depending on the level of the paint color production ratio.
