Problems solved by technology
Since the control systems of the various motors and burners of the coating equipment in the prior art operate independently, the production of the coating line may vary due to different workpieces, equipment abnormalities, and quality defects (such as steel corrosion, cold-working incoming materials, grinding marks), etc. The reason is that the takt time of each process is unbalanced, some workpieces have a long waiting time, and all the motors and burners are turned on during the waiting time, and they are in an invalid working state for a long time, resulting in a large waste of energy consumption and Affect the service life of the equipment

Embodiment Construction
[0011] Such as figure 1 As shown, an energy consumption control system for coating equipment includes a detection device installed on the conveyor chain to detect whether there are workpieces at each station of the coating equipment, a PLC connected to the detection device, and multiple Relay, PLC controls the start and stop of the motor or burner at each station of the coating equipment through the corresponding relay; When an adjacent station is a vacant signal, the PLC will switch the motor or burner of this station to make it run at low frequency or stop, and the working time set by each station workpiece minus its actual working time is less than the set value , or when the previous adjacent station of this station is a full signal, the motor or burner of this station is in normal operation. If the adjacent next station of this station is an empty signal, after the work of this station is completed, the PLC sends a signal to make it move to the next adjacent station.

The invention discloses an energy consumption control system for painting equipment, and relates to the technical field of energy consumption control for painting equipment. In the present invention, a detection device for detecting whether there are workpieces at each station of the coating equipment is installed on the conveying chain, a PLC connected with the detection device, and a plurality of relays connected with the PLC, and the PLC controls each of the coating equipment through the corresponding relays. The start and stop of the station motor or the burner; when the working time set by each station workpiece minus its actual working time is greater than or equal to the set value, or when the previous station adjacent to the station is an empty signal, the PLC will Switch the station to make it run at low frequency or shut down. When the working time set by each station workpiece minus its actual working time is less than the set value, and the previous station adjacent to this station is a full position signal , the station is in normal operation. Make the effective running time of the coating equipment reach more than 90% of the actual effective running time, and reduce the energy consumption during the waiting time.
Description
technical field [0001] The invention relates to the technical field of energy consumption control of painting equipment, in particular to an energy consumption control system of painting equipment. Background technique [0002] The energy consumption system of the painting equipment is composed of a variety of high-power motors and burners. The motors mainly include the exhaust fan of the spray booth, the air supply fan of the spray booth, the circulating water pump of the spray booth, the air supply fan of the dust scraping and grinding room, and the exhaust fan of the dust scraping and grinding room , Forced cold room fan, burner mainly includes burner in moisture drying room, burner in primer drying room, burner in top paint drying room. Since the control systems of the various motors and burners of the coating equipment in the prior art operate independently, the production of the coating line may vary due to different workpieces, equipment abnormalities, and quality def...
