Abstract
The utility model belongs to a control device for accurately releasing a single steel plate. The device comprises a lifting electromagnet (4),a three-phase bridge-type fully-controlled rectifying circuit (2), a voltage transformer (3), an analog-digital conversion module (6) and a trigger signal driving circuit (10), and is characterized in that a PLC (Programmable Logic Controller) control module (9) is connected between the trigger signal driving circuit (10) and the analog-digital conversion module (6), and the PLC control module (9) is connected with a single steel plate release button (7). The device disclosed by the utility model can be used for accurately releasing the single steel plate and is accurate to control and simple to operate; and the working efficiency is remarkably improved.
Description
Technical field
The utility model belongs to lifting appliance, particularly a kind of control setup of accurate release single steel plate.
Background technology
With electromagnet handling steel plate the time, majority requires the electromagnet system namely can many steel plates of lifting, can accurately put down a steel plate again when many steel plates of lifting at every turn, and then other steel plates is relieved a garrison respectively other are different local.The problem that present domestic electromagnet lifting appliance exists is: the control setup that has discharges single steel plate by the field switch of quick power on/off magnet, and this method is often put inaccurate, or puts one more, or puts down entirely, fail to lay down.Also have carry out steel plate by the size that adopts potential device to regulate magnetic force in control system individual discharge, this mode exists complicated operation, the time is long, efficient is too low problem.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, provide a kind of control accurate, the control setup of accurate release single steel plate simple to operate.
The technical scheme that the utility model technical solution problem adopts is: a kind of control setup of accurate release single steel plate, comprise lifting electromagnet, three-phase full-bridge controlled rectifier, voltage transformer, analog-to-digital conversion module and energizing signal driving circuit, it is characterized in that connecting a PLC control module between energizing signal driving circuit and analog-to-digital conversion module, the PLC control module is connected with the single steel plate release-push.
The beneficial effects of the utility model are: this utility model can discharge single steel plate accurately, and control accurately, and is simple to operate, significantly improved work efficiency.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 is the electrical principle diagram of block that accurately discharges the control setup of single steel plate.
Among the figure: the 1-rectifier transformer; The 2-three-phase full-bridge controlled rectifier; The 3-voltage transformer; The 4-lifting electromagnet; The 5-current transformer; The 6-analog-to-digital conversion module; 7-single steel plate release-push; The 8-energizing circuit; The 9-PLC control module; 10-energizing signal driving circuit.
The specific embodiment
Embodiment, with reference to accompanying drawing, a kind of control setup of accurate release single steel plate, comprise lifting electromagnet 4, three-phase full-bridge controlled rectifier 2, voltage transformer 3, analog-to-digital conversion module 6 and energizing signal driving circuit 10, it is characterized in that connecting a PLC control module 9 between energizing signal driving circuit 10 and analog-to-digital conversion module 6, PLC control module 9 is connected with single steel plate release-push 7.Rectifier transformer 1 connects 380V power supply and three-phase full-bridge controlled rectifier 2, three-phase full-bridge controlled rectifier 2 is connected with lifting electromagnet 4, middle voltage transformer 3 in parallel, the current transformer 5 of connecting, current transformer 5 all is connected with analog-to-digital conversion module 6 with voltage transformer 3; Energizing circuit 8 is connected with PLC control module 9; Energizing signal driving circuit 10 is connected with three-phase full-bridge controlled rectifier 2.
Working process is like this, and during normal operation, PLC control module 9 output excitation trigging pulses by trigger element control three-phase full-bridge controlled rectifier 2 output field voltages, play many steel plates for lifting electromagnet 4 power supplies and lifting; When single steel plate discharges, press the single steel plate release-push, this control signal is sent to PLC control module 9, and begin the stepless output voltage of turning down energizing circuit 8 immediately, and the amplitude that field voltage reduces is by pressing time control that single steel plate release-push 7 presses, the time of pressing is more long, voltage is just more low, when finding that nethermost a kind of steel plate falls, unclamp single steel plate release-push 7 immediately, magnetic force is got back to maximum magnetic force state again automatically.Putting down nethermost 3 seconds of needs.Need turn-off energizing circuit 8 so put down last steel plate, steel plate can put down in 2 seconds.
