The specific embodiment
The contrast Figure of description is described in further detail below:
As Fig. 1, Fig. 2, Fig. 7, shown in Figure 8, the connected mode and the action relationships of staircase floor plates upper surface sbrasive belt grinding equipment of the present utility model are as follows: driving wheel 2 is driven by driver motor 1, and abrasive band 4 is on driving wheel 2 and driven pulley 3.At first positive stop 9 is risen the feed entrance point of control floor plates during charging by positive stop hoist cylinder 10.By carriage hoist cylinder 14,14 ' grinding station carriage and raceway 13 are risen then, make grinding station raceway concordant with charging raceway 8.Then the feed station motor 7 that is connected with charging raceway 8 starts with the grinding station motor 15 that is connected with raceway 13 with grinding station carriage, and floor plates is sent to grinding position.After sensor detects floor plates arrival grinding station, Programmable Logic Controller PLC28 sends signal, carriage hoist cylinder 14,14 ' sinks grinding station carriage and raceway 13, floor plates is placed on the clamp, backstop hoist cylinder 12 rises backstop 11, thruster plate telescopic oil cylinder 19 stretches out thruster plate 18, and floor plates is fixed on the anchor clamps.After sensor detects floor plates and is fixed, Programmable Logic Controller PLC28 sends signal, form wheel lifting magnetic valve 22 descends form wheel hoist cylinder 6,6 ' piston, and the form wheel that is connected with form wheel hoist cylinder 6,6 ' 5,5 ' is pressed on abrasive band 4 and carries out grinding on the floor plates.Programmable Logic Controller PLC28 picks up counting simultaneously, and after the grinding time reached setting-up time, Programmable Logic Controller PLC28 gave an order, form wheel lifting magnetic valve 22 makes form wheel hoist cylinder 6,6 ' piston-retraction, floor plates is left in abrasive band 4, and grinding stops, but driver motor 1 does not stop.Simultaneously carriage hoist cylinder 14,14 ' rises grinding station carriage and raceway 13, makes grinding station raceway concordant with discharging station raceway 16.Then positive stop hoist cylinder 10 is with positive stop 9 withdrawals, backstop hoist cylinder 12 is with backstop 11 withdrawals, the discharging station motor 17 that connects discharging station raceway 16 starts with the grinding station motor 15 that is connected grinding station carriage and raceway 13, and floor plates is sent to the discharging position.After sensor detected floor plates arrival discharging position, discharging station motor 17 and grinding station motor 15 stopped, and thruster plate telescopic oil cylinder 19 is with 18 withdrawals of thruster plate.At this moment the state of all executive components is got back to and is opened the beginning state, finishes a grinding circulation, waits for next piece floor plates input.
In order to guarantee safety and to prevent that the grinding particle from dispersing, safe coaming plate 20 is housed around the grinding station.Grinding process carries out within coaming plate, and except grinding station carriage and raceway 13, other movement parts are arranged in the coaming plate outside.The dust arrester 21 of bleeding is housed on the safe coaming plate 20 metallic particles that grinding produces is extracted out, prevent that metallic particles from accumulating in and cause the movement parts excessive wear on the machine.
As Fig. 3, Fig. 4 and shown in Figure 5, its control principle of control method of the present utility model and process are as follows: the state of all executive components in this device, detected by sensor as the diverse location that opens/stop with floor plates of the stretching out/withdraw of oil cylinder, motor, and input to Programmable Logic Controller PLC28.Programmable Logic Controller PLC28 output command is after treatment controlled corresponding executive component by relay, as the coil of magnetic valve or the contactor coil of motor, whether the coil of magnetic valve has the position of electric control valve core of the electromagnetic valve, thus the state of control oil cylinder; Contactor is controlled opening/stopping of motor.Therefore Programmable Logic Controller PLC28 is the control maincenter of this device, and working procedure also is stored among the Programmable Logic Controller PLC28.
Before floor plates was sent to the discharging station from the grinding station after grinding was finished, Programmable Logic Controller PLC28 will judge earlier whether the discharging station has floor plates.If the workman has little time from the discharging station floor plates to be taken away, promptly go out when on the material level floor plates being arranged, then postforming wheel 5 is finished in grinding, 5 ' lifts, grinding station carriage and raceway 13 also rise, but discharging station motor 17 and grinding station motor 15 do not start, and the intact floor plates of grinding does not transmit to going out material level.If the discharging station did not have floor plates when grinding was finished, then the floor plates after the grinding need not waited for, directly is sent to the discharging station.Equally, floor plates will judge earlier from feed station Programmable Logic Controller PLC28 before the grinding station transmits whether the grinding station has floor plates.If the grinding station has floor plates, then the floor plates of feed station does not transmit to the grinding station.After the floor plates of grinding station was seen off, the floor plates of feed station just transmitted to the grinding station.In order to make the equipment operate as normal, also need to add centralized lubrication device 29, radiator fan 30, portable lamp and power supply etc.
As shown in Figure 6, its control principle of control method of the present utility model and process are as follows: the signal input has 29 points, and it is allocated as follows: flexible state 12 points of oil cylinder, i.e. X2-X7, X10-X15; 5 of the startups of motor are X16, X17, X20-X22; Motor overheating detects 2 point, i.e. X23-X24; Position 3 point, the i.e. X25-27 of floor plates; The oil temperature detects 1 point, i.e. X30; Oil pressure detects 1, promptly puts X31; Fuel head 1 point, i.e. X32; Principal axis lubrication state 1 point, i.e. X33; Promptly stop 1 point, i.e. X35; Work loop 1 point, i.e. X34; RESET 1 point, i.e. X36 resets.The signal of all the sensors is directly passed to the input point of logic programmable controller PLC28.Output has 14 points, is respectively: coil 5 points of magnetic valve, i.e. Y1-Y5, contactor 6 points of motor, i.e. Y6-Y7, Y10-Y13, alarm lamp 1 point, i.e. Y14, work " wait " light 1 point that is over, i.e. Y15, lamp 1 point, i.e. Y16 working properly.The output of logic programmable controller PLC28 directly connects with the control object.If when when the different floor plates of grinding, needing different abrasive bands speed, can realize different grinding speeds by the speed setting that changes spindle inverters 31.
Control flow shown in Figure 7 is as follows:
A, processing beginning, driver motor, Oil pump electrical machinery start Programmable Logic Controller PLC initialization;
Whether b, detection grinding station have workpiece, if do not have, enter next step c; If have, then enter step g;
Whether c, detection feed station have workpiece, if do not have, then enter cycle detection, i.e. wait state; If have, then enter next step d;
D, control grinding station carriage rise, positive stop rises;
E, feed station electric motor starting, the grinding station motor starts, and is fed to the grinding station;
F, control backstop rise, grinding station carriage descends, the thruster plate stretches out;
