Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is PLC control circuit figure of the present invention;
In figure, each member is: 1 the 3rd approach switch, 2 second approach switchs, 3 tracks, 4 first approach switchs, 5 walking dollies, 6 magnechucks, 7 halfpaces, 8 funnels, 9 metal detectors.
The specific embodiment
The invention will be further described below in conjunction with embodiment and with reference to accompanying drawing.
a kind of sucked type Deironing mechanism as described in Figure 1, comprise metal detector 9, PLC controller and electromagnetic mechanism, described electromagnetic mechanism comprises magnechuck 6 and walking dolly 5, be provided with magnechuck 6 on described walking dolly 5, be provided with position-sensing switch on the track 3 of described walking dolly 5, the switch of described location is approach switch, described position-sensing switch is provided with 3, be provided with the first approach switch 4 on the track above described belt, be provided with the second approach switch 2 on the track above halfpace 7, and be provided with the 3rd approach switch 1 on the track on the funnel 8 that is used for the placement excessive iron, by using contactless approach switch, greatly improved the service life of position-sensing switch.
A modification of the present invention is provided with running trolley self-insurance program in described PLC controller, by the self-insurance program is set, increased the standby memory function of automatic de-ironing device,, prevented the loss of switching signal.
A modification of the present invention, the voltage of the power supply of described approach switch is identical with the input point voltage of described PLC controller, by arranging the voltage of the power supply of approach switch identical with the input point voltage of PLC controller, can make approach switch directly by PLC controller in-line power, and do not need to provide external power source, guaranteed that on-the-spot Electrical Safety is reliable.
A modification of the present invention, described approach switch power supply is DC24V, has reduced cost by using the low pressure approach switch.
A modification of the present invention, described approach switch are the approach switch that spacing is greater than or equal to 4mm.
the course of work of the present invention is as follows: walking dolly is parked on the track 3 of belt top and carries out standby, when the Belt Conveying ore, through metal detector 9 places, when metal detector 9 detects on belt when crossing iron, issue a signal in the PLC controller, the PLC controller is according to the program that sets in advance, allow magnechuck encourage by force suction iron, this moment is owing to encouraging by force suction iron due to magnechuck, adsorbed on magnechuck except excessive iron, also adsorbed a part of iron ore, walking dolly left lateral afterwards, when the walking dolly left lateral during to second approach switch 2 at halfpace place, the second approach switch 2 sends signal and passes in the PLC controller, the magnetic of the programme-control magnechuck that sets in the PLC controller, the magnetic of magnechuck is weakened, walking dolly stops, some iron ores that adsorb on magnechuck this moment will fall on halfpace, then walking dolly continues left lateral to the funnel place that is used for placing excessive iron, when walking dolly during near the 3rd approach switch 1, the 3rd approach switch 1 sends instruction to the PLC controller, the PLC controller carries out demagnetization according to the programme-control magnechuck that sets, after the magnechuck demagnetization, absorption with magnechuck on iron will drop with funnel in.Then, walking dolly is turned one's head right lateral, when walking dolly during near second approach switch 2 at halfpace place, approach switch sends signal and passes in the PLC controller, and the programme-control magnechuck that sets in the PLC controller is encouraged the iron ore on halfpace by force and sucked back, and then the dolly right lateral is to first approach switch 4 places at starting point place, approach switch sends signal to the PLC controller, the PLC controller carries out standby according to the program of setting with walking dolly, completes thus the circulation of a job.
Because metal detector may be surveyed for a long time less than crossing iron on belt, walking dolly may rest on position of readiness for a long time, cause the first 4 working times of approach switch of belt top dolly standby position oversize, and the approach switch working time is oversize, can cause switching signal to lose sometimes memory, so need add one section running trolley self-insurance program in the PLC control program, increased the standby memory function of automatic de-ironing device, can automatically terminate self-insurance again after dolly work.
the PLC control circuit of dolly self-insurance program of the present invention is as described in Fig. 2, when walking dolly is in position of readiness, the first approach switch 4 of being located at belt top sends signal, this moment, the normal open switch of relay X000 was closed, coil M240 connects, normal open switch 240 is closed simultaneously, coil M240 forms self-locking, keep holding state, not can because of and the approach switch working time oversize, can cause switching signal to lose sometimes memory, when the metal detector acquisition of signal is crossed iron to belt, send signal, X021 connects, due to normal open switch 240 closures, so relay coil M230 is closed, coil M230 is closed, normal open switch 230 closures, relay coil M231 is closed, while normal open switch 231 closures, coil M231 self-locking, be used to come the iron memory, due to normal open switch 230 closures, normal open switch 240 closures, coil M237 connects, the closed formation self-locking of normal open switch 237 simultaneously, prepare to inhale iron charge.
The above is only preferred embodiment of the present invention, is not to be the present invention to be done the restriction of any other form, and according to any modification or equivalent variations that technical spirit of the present invention is done, still belongs to the present invention's scope required for protection.
