6, adopt light current control, electrical security height.
Description of drawings
Fig. 1 is a circuit structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing 1 a kind of embodiment of the present utility model is described.
The adobe that is used to fall the plate machine panel control system that falls automatically, has frequency converter 1, frequency converter 1 has multistage speed and simple and easy PLC function, the input end R of frequency converter 1, S, T is connected with the input of electrical network three phase mains, three power take-off U of frequency converter 1, V, W connects the input end of carrying motor 8, carry motor 8 to drive load-transfer device, the control terminal CM of frequency converter 1, M1, M5, M6 links to each other with the control output end of logic control element 2, logic control element device 2 has I/O of many signals and logical process function, and the control terminal of frequency converter 1 can call its built-in multistage speed, emergency protection and function such as reset; The signal input part of logic control element 2 connects base travel switch 3, express delivery travel switch 4, express delivery travel switch 5 and the plate that the falls travel switch 9 that puts in place that puts in place respectively, obtaining position signal and to handle these signals, the base travel switch 3 that falls, express delivery travel switch 4, express delivery travel switch 5 and the plate that the falls travel switch 9 that puts in place that puts in place all has passive open contact; Wherein, the base travel switch 3 that falls gathers the base signal, holds blanket because the downward landing of deadweight touches base travel switch 3, and automatic cutout signal when falling to being put on the load-transfer device holds the blanket landing to treat the next one; Just run into express delivery travel switch 4 when holding when blanket arrives specified quantity, thereby call at a high speed, all are held blanket deliver to board fast, and touch the express delivery travel switch 5 that puts in place, thereby the startup board falling device touches the plate travel switch 9 that puts in place after the plate that falls puts in place, the automatic drawing back grillage that falls.Another control output end of logic control element 2 meets the coil KM of AC contactor 6, break-make in order to control AC contactor 6, AC contactor 6 is by open contact 10 control Oil pump electrical machineries 7, open contact 10 1 termination three-phase power input ends, the input end of its another termination Oil pump electrical machinery 7, thereby the start and stop of control Oil pump electrical machinery 7, Oil pump electrical machinery 7 drives the grillage lifting.
