Actual below in conjunction with producing, further describe the present invention.
Wait to lift workpiece and be band muscle aluminium sheet, the no gas permeability in surface.
Band muscle aluminium sheet characteristic:
Profile: 10000mm (length) * 3000mm (wide) * 8mm (thick).
Muscle is high: 100mm, muscle spacing: 250mm, direction: vertically arrange.
Weight: maximum is about 1000kgs.
According to band muscle aluminium sheet surface of the work characteristic; The most smooth distance is about 65mm among the muscle spacing 250mm; Then a selectable size is less than the vacuum cup 17 of 65mm; Because vacuum cup 17 diameters are little, so the suction that single vacuum cup 17 is produced is also less, and hanging the quantity of sending the required vacuum cup 17 of workpiece then needs more.Preferred dimension is the oval vacuum cup 17 of 55mm * 300mm here, and vacuum cup quantity is 48, and the suction of single sucker is 25kgf (under 60% vacuum, measuring), and total suction reaches 25kgf * 48=1200kgf, satisfies to hang and send requirement.
Because vacuum cup 17 quantity are more; For making each vacuum cup 17 and the abundant combination seal of plate surface; On each sucker, be provided with buffering stand and universal hinging fixator; Utilize the self-regulating function of buffering stand and universal hinging fixator to make each vacuum cup 17 and the abundant combination seal of plate surface, all be furnished with manual ball valve 31 on vacuum cup 17 tops simultaneously.
For ensureing that vacuum cup 17 hangs the reliability of sending; The present invention is provided with the vacuum accumulator device, and the vacuum accumulator device can remedy vacuum cup 17 owing to reveal the vacuum decline that causes, and causes vacuum cup 17 suction not enough; Prevent that effectively workpiece from dropping, improve and hang the safety coefficient of sending.Another effect of vacuum accumulator device is when apparatus of the present invention are cut off the power supply suddenly, makes the vacuum pressure of system drop to 30% o'clock required time more than or equal to 5 minutes by the highest, for plenty of time is reserved in operator's hedging and emergency action.Because the vacuum accumulator device is not a pressure vessel.Therefore, the inner space that the girder 20 that is provided with is gone up by the auxilliary beam 2 that is provided with on this device utilization connection two C type roof beams structure and the row of hanging is as the two-way vacuum accumulator device that can keep the certain vacuum degree respectively.
Wherein:
The inside dimension of auxilliary beam 2 is 130mm * 130mm * 2500mm=42250000mm
3=42.25L constitutes a vacuum accumulator device thus.
The inside dimension of its girder 20 is 100mm * 100mm * 8000mm=80000000mm
3=80L constitutes another vacuum accumulator device thus.
Apparatus of the present invention also are provided with alarm unit; When can not satisfying carrying, vacuum requires under the perhaps unexpected situation of cutting off the power supply; Alarm unit sends the sound and light alarm signal through alarm lamp 8 alarms such as grade; Remind the operator cannot lift by crane or take rapidly to be ready measure, frock and equipment are dropped to home or safe altitude.
Switching mechanism through apparatus of the present invention; In the process of lifting workpiece; Can pass through electric cabinet 10 operation of drive motor 15; Along with the rotation of drive motors 15, be arranged on driven wheel 22 on the output axle head of this drive motors 15 and also rotate thereupon, and drive simultaneously with its intermeshing turning gear 21 and also rotate synchronously.Ordering about the girder 20 that is fixedly connected with turning gear 21 thus rotates in 0-180 degree scope.Rotation just because of girder 20; All suspension brackets 16 that drive is fixed on the girder 20 overturn synchronously, thereby reach the purpose of the whole aluminium gusset 34 workpiece upset of control, and drive motors 15 self has self-locking structure; Can stop handled easily person's installation or process operation at an arbitrary position.Because the girder 20 in the present embodiment in the row of hanging is longer, consider to adopt 2 drive motors 15.
The computational methods of drive motors 16:
1) workpiece weight=1200KG, the arm of force=0.35;
2) rotating shaft output torque:
T1＝1200×0.35+240×0.09＝442KG.M＝4420N.M；
3) big pinion is than=4.5: 1;
4) reductor output torque:
T2＝T1/5＝4200/4.5＝983N.M；
5) separate unit reductor output torque:
T2*/2＝933.4/2＝492N.M；
6) setting was turned over and is turn 90 degrees in 12 seconds, and then the reductor output speed should be 5.6r/min;
7) consider reliability and safety coefficient, suitable amplification reserve is with reference to the motor reducer sample
Selected model is: RV90/WB120-290YEJ-0.75F1-DZ.
Oilless vacuum pump 33 is selected the SV1040-380V-1.25KW oilless vacuum pump of German BUSCH company for use, through non-stop run, for equipment provides vacuum source.These vavuum pump 3 maximum vacuums are 85%, and power is 1.25KW, and flow is 40M
3/ h.
In addition; In actual use; Apparatus of the present invention are suspended on the suspension hook of crane, consider that hanging piece center of gravity in switching process possibly squint, and apparatus of the present invention are provided with three hangers 4 of distribution triangular in shape in C type roof beam structure upper edge; Three shackle structures can effectively prevent equipment owing to the asymmetric unbalance loading that causes of distribution of weight when drawing workpiece, thereby make held stationary state in the workpiece switching process.
1. the harmless carrying vacuum of aluminum alloy plate materials (and band muscle aluminium sheet) is hung arranging device, can carry out vacuum to aluminum alloy plate materials (and band muscle aluminium sheet) and hang row's carrying and carry out 0 ° to 180 ° upset (all can pause in any position, and can control angle) midway;
2. in order to improve the security reliability of vacuum system, avoid working as the leakage of vacuum tube road and cause load to fall down.Be divided into independence two tunnel to vacuum system, divide two the tunnel, isolate, use two cover vacuum accumulator devices, divide two groups of A, B, be staggeredly placed, and distinguish with red, blue tracheae to sucker with check valve at vacuum pump outlet.
3. it is liftoff higher to consider that aluminium alloy plate vacuum when upset is hung row, increases by a cover wire controlling button box, the convenient use.
4. the harmless handling vacuum of aluminum alloy plate materials is hung arranging device, can hang row's the size and the quantity of sucker according to the area and the weight setting of aluminium sheet.
