The cooresponding parts title of label is in the accompanying drawing: 1-transmission structure pedestal; The 2-heavy workpiece; The 3-frequency converter; The 4-transmission shaft; 5-transfers bench board; The 6-jacking system; 7-PLC control unit; 8-HMI read out instrument; The 9-control button; 10-imports button; 11-transfers dolly; 12-dolly transverse bracket; 13-dolly wheel; The little car pull bar of 14-; 15-dolly longitudinal support.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is done to specify further, but embodiment of the present invention is not limited thereto.
Like Fig. 1, shown in Figure 2; The workpiece driving system based on PLC control of present embodiment; Comprise transmission structure pedestal 1, transmission shaft 4, transfer table 5, jacking system 6, transfer dolly 11, PLC control unit 7, transmission shaft 4 is fixedly set on the transmission structure pedestal 1, the sheathed transport tape that is equipped with on the transmission shaft 4; Heavy workpiece 2 places on the transport tape; End near transport tape 4 sense of motions is provided with transfer table 5, and transfer table 5 is fixedly mounted on the jacking system 6, and the width of said transfer table 5 is less than the width of heavy workpiece 2; Said transfer dolly 11 comprises the dolly longitudinal support of captiveing joint with dolly transverse bracket 12 respectively in two dolly transverse brackets 12 that are parallel to each other and two ends 15; Two dolly transverse brackets 12 are respectively equipped with dolly wheel 13; The hollow spacing that constitutes between two dolly transverse brackets 12 is greater than the width of transfer table 5 and less than the width of heavy workpiece 2; Said transmission shaft 4 directly links to each other with the clutch end of drive motor or through belt-driving or through gear transmission, jacking system 6, drive motor link to each other with PLC control unit 7 through control path.
When transferring on the transfer table for the ease of heavy workpiece, the operation that PLC automatic guidance lifting mechanism descends; Said transfer table 5 is provided with the gravity sensing element, and the gravity sensing element links to each other with PLC control unit 7 through circuit.
Said PLC control unit 7 is provided with the control button 9 that control jacking system 6 and drive motor switch under the open and close state, and also is provided with HMI read out instrument 8 on the PLC control unit 7 and imports button 10.
For the controlling and driving rotating speed of motor, with the rotating speed of further control transmission shaft, thereby play the speed that the control heavy workpiece shifts, on said drive motor and control path that PLC control unit 7 links to each other, also be provided with frequency converter 3.
Shift dolly for the ease of moving, on said dolly longitudinal support 15, be fixedly connected with dolly pull bar 14.
Working process of the present invention is following: as shown in Figure 1; Heavy workpiece is positioned at the left end of transport tape; Before the control button that starts on the PLC control unit; The side with hollow depression who shifts dolly is pushed in facing to transfer table, and the hollow spacing that constitutes between two dolly transverse brackets is greater than the width of transfer table and less than the width of heavy workpiece, when making that transfer table falls after the transfer dolly is pushed under the effect of lifting mechanism; Lifting mechanism and transfer table just in time can fall from the part of dolly hollow depression, and heavy workpiece just in time can fall to being placed on two dolly transverse brackets.
After carrying out these preparations, start the control button on the PLC control unit, and set a time-delay through input media; Like 10S, this time-delay is that the gravity sensing element senses is under pressure to transfer table after sensing heavy workpiece and transferring on the transfer table; Provide an actuation signal to the PLC control unit; The PLC control unit waits for that 10S starts lifting mechanism, makes lifting mechanism descend, after lifting mechanism drops to certain distance; Heavy workpiece falls to being placed on two dolly transverse brackets, just can heavy workpiece be removed through moving the transfer dolly.At this time the pressure that receives to transfer table of sense element senses disappears, and provides a danger signal to the PLC control unit, makes the lifting mechanism stop motion.We also can confirm the unlatching of lifting mechanism and stop through the mode that distance perspective is answered.
To heavy workpiece be moved in placely, only need above mobile operating sequence promptly can be realized conversely.The dolly that promptly will be mounted with heavy workpiece earlier moves on the transfer table that is in low level, and start lifting mechanism this moment, is in sustained height up to the lower surface and the transport tape of heavy workpiece.Get on for the ease of heavy workpiece is moved to transport tape, several axis of rolling that can roll can be set or the pearl that rolls on the table top of transfer table, make heavy workpiece to move on the transport tape easily.
As stated, just can realize the present invention preferably.
