Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.
From the embodiment shown in Fig. 1-4, the present embodiment comprises the cylindrical housings 1 by bracing frame fixed support, cylindrical housings 1 ring madial wall is provided with adjacent feed space 2 and discharge chamber 3, feed space 2 and discharge chamber 3 are respectively equipped with charging aperture and discharging opening, next-door neighbour's feed space 2 and discharge chamber 3 are respectively equipped with left isolation ward and right isolation ward, the multiple working position 5 of circular row between left isolation ward and right isolation ward, each working position 5 arranges a nozzle 4, the turntable of hanging foundry goods is provided with in cylindrical housings 1, turntable rotating shaft 6 and cylindrical housings 1 concentric, turntable rotating shaft 6 is driven to drive turntable to operate by motor 7, also be provided with PLC automatic control system: PLC can select S7-300 series 6ES7322-1HH01-0AA0, digital quantity input module model is EM221, and digital output module model is SM322, motor drives turntable step-by-step movement to operate by rotary slicer 8, rotary slicer 8 model: RU180DF-12-270-2R-S3-VW-2P/X, rotary slicer 8 step angle is 30 degree, angular displacement output shaft 11 and the turntable rotating shaft 6 of rotary slicer 8 are in transmission connection, feed space 2, discharge chamber 3, left isolation ward, right isolation ward and each working position 5 the equalization that occupies, be 12 equal portions altogether, angular displacement output shaft 11 step angle is identical relative to the corresponding angle at cylindrical housings 1 center with each operated adjacent position 5, also comprise the start button be connected with PLC digital quantity input, stop button, grating sensor 9, grating sensor 9 model: LSL35-8J-4J, with turntable displacement transducer, motor 7 and nozzle compressed air control valve 10 control by PLC digital output signal, grating sensor 9 is for detecting charging aperture and whether discharging opening front end human body exists, the transmitting terminal of grating sensor 9 and receiving terminal are installed on the two ends, outside of charging aperture and discharging opening respectively, turntable displacement transducer comprises following structure: angular displacement output shaft 11 is provided with cam, and the gear teeth 13 annular of cam is all listed in the circumference of angular displacement output shaft 11, the gear teeth 13 of cam are 12 altogether, and are provided with the proximity switch 12 detecting the conversion of the gear teeth 13 position, and proximity switch 12 is turntable displacement transducer.
Operation principle:
Press start button, operating personnel put into No. 1 foundry goods for clearance to charging aperture, after PLC detects by grating sensor the switching signal that personnel leave, send switching signal control motor 7 to operate, rotary slicer 8 stepping once, now keep synchronous cam in turntable displacement transducer also stepping is once with angular displacement output shaft 11, after proximity switch 12 detects this switch (stepping) signal, output switching signal shuts down to PLC control motor 7, completes the action that No. 1 foundry goods is automatically brought to right isolation ward, operating personnel put into No. 2 foundry goods for clearance to charging aperture again, after grating sensor detects the switching signal that operating personnel leave, send a switching signal, PLC receives this switching signal and repeats above-mentioned control instruction, control the automatic stepping of turntable once, No. 1 foundry goods for clearance and No. 2 foundry goods enter No. 1 working position and right isolation ward respectively, (work item order be arranged in order according to turntable rotation direction) detects that grating sensor sends twice switching signal (namely thinking that No. 1 working position has foundry goods to be cleaned) as PLC, namely the nozzle compressed air control valve 10 controlling No. 1 working position is opened, No. 1 working position nozzle is started working, when PLC detects that grating sensor sends tertiary switch signal (namely thinking that No. 2 working positions have foundry goods to be cleaned), namely the nozzle compressed air control valve 10 controlling No. 2 working positions is opened, No. 2 working position nozzles are started working, by that analogy, until all working position nozzle is all started working, as long as avoid the energy waste phenomenon that a starting device all working position nozzle is all started working caused.
After last 1 foundry goods for clearance is put into charging aperture by operating personnel, take No. 1 foundry goods cleared up away simultaneously, and press stop button, then program enters car-parking model automatically, when operating personnel's second time takes off No. 2 foundry goods cleared up, No. 1 working position has not had foundry goods capable of washing, now PLC detects that grating sensor sends twice switching signal (namely thinking that No. 1 working position has not had foundry goods to be cleaned), namely the nozzle compressed air control valve 10 controlling No. 1 working position is closed, No. 1 working position nozzle quits work, when operating personnel take off No. 3 foundry goods cleared up third time, No. 2 working positions have not had foundry goods capable of washing, now PLC detects that grating sensor sends tertiary switch signal (namely thinking that No. 2 working positions have not had foundry goods to be cleaned), the nozzle compressed air control valve 10 controlling No. 2 working positions is closed, No. 2 working position nozzles quit work, by that analogy, until all workpiece all take out, all working position nozzle all quits work, avoid and do not have the working position nozzle of foundry goods to be cleaned blindly to work the energy waste caused.
In upper and lower pieces process, as long as PLC is detected by grating sensor the switching signal that personnel exist namely control motor stalling, turntable can not move.In turntable moving process, if any having people or foreign matter to enter detection zone, PLC detects this signal by grating sensor, then turntable stops mobile automatically, has ensured production safety.
This equipment is to the operation requirements of operating personnel:
PLC relies on start button, stop button and grating sensor to judge working position residing for foundry goods, therefore enters grating sensor surveyed area to operating personnel at every turn and operates and all there are certain requirements.
When 1, starting working, operating personnel press start button, put into foundry goods for clearance simultaneously, leave afterwards to charging aperture.
2, after last 1 foundry goods for clearance is put into charging aperture by operating personnel, cleaned if any foundry goods, taken the foundry goods cleared up simultaneously away, and press stop button, leave afterwards.
3, the action that operating personnel are once complete is: often enter a grating sensor surveyed area, puts into a foundry goods to be cleaned, has cleaned if any foundry goods, is taken out by cleaned foundry goods while putting into foundry goods to be cleaned again.
