Description of drawings
Fig. 1 is the structural representation of small capacitor aluminium stretcher automatic discharging device of the present invention;
Fig. 2 is the right view of Fig. 1;
Fig. 3 regulates program flow diagram for the drawstring speed of automatic discharging device of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Embodiment
As shown in Figure 1, a kind of small capacitor aluminium stretcher automatic discharging device mainly comprises: mainly comprise: 1 active strap wheel, and 2 auxiliary strap wheels, 3 limit switches, 4 derive wheel, 6 strip detecting units, 7 casings, 8 motor, 9 ECUs etc. are partly formed.Wherein 6 strip detecting units mainly comprise: detect axle, test rod is every mating plate and two compositions such as flute profile photoelectric sensor.
1 active strap wheel and 2 auxiliary strap wheels are installed in the upper left corner in 7 casings, and 2 auxiliary strap wheels rely on spring forces to abut against on the 1 active strap wheel; 8 motor are installed in the outside of 7 casings by support, and the axle of 8 motor and 1 is spool directly linking to each other of strap wheel one side initiatively; 6 strip detecting units are installed in the casing; 3 limit switches are installed in the top in 7 casings; 4 derive the upper right corner that wheel is installed in 7 casings; 9 ECUs are installed in the outside of 7 casings.
During the automatic discharging device operation, on the one hand, strap wheel is drawn in the aluminium strip in the casing, the following vertical plane position of strip has a declining tendency, and on the other hand, stretching-machine charging mechanical device is ceaselessly pulled out the aluminium strip in casing, send into stretching-machine, there is the trend of rising the following vertical plane position of strip.
Establish two positions of the strip upper limit and strip lower limit in the casing, the strip upper limit position is in the middle and upper part of casing, the strip lower position is in the bottom of casing, the test rod of strip detecting unit is attached under the strip on the vertical plane, along with the decline or the rising of vertical plane position under the strip, the strip detecting unit send detected strip position signalling and sends a telegraph the control unit.After vertical plane under the strip dropped to below the lower position, it was high level that detecting unit is sent down limited signal, and last limited signal is a low level; When vertical plane under the strip rises to more than the lower position and after being lower than upper limit position, it is low level that detecting unit is sent down limited signal, last limited signal is a low level; After vertical plane under the strip rose to more than the upper limit position, it was high level that detecting unit is sent limited signal, and following limited signal is a low level.Position and the strip detecting unit signal relation sent of strip in casing is as shown in table 1.
Position and the strip detecting unit signal relation sent of table 1 strip in casing
| Sequence number | The strip position | Last limited signal (level) | Following limited signal (level) |
| 1 | Be higher than the upper limit | High | Low |
| 2 | Be lower than the upper limit and be higher than lower limit | Low | Low |
| 3 | Be lower than lower limit | Low | High |
In order to guarantee that strap wheel does not damage the aluminium strip when drawing material, limit the peak acceleration of strap wheel, the peak acceleration Amax of strap wheel is determined by following formula:
Amax＝2*Vmax/(Lx-Ls) (1)
(1) in the formula: Vmax is the stretching-machine maximum feed velocity
Lx is the length of strip when the lower position
Ls is the length of strip when upper limit position
The value of Lx and Ls is relevant with the setting of casing size and bound position, suitably adjusts casing size and bound position, can make Amax below setting.
ECU is constantly regulated the rotating speed of motor according to the strip position signalling, thereby regulates the speed of drawstring, and drawstring speed is regulated program flow diagram as shown in Figure 2.
After small capacitor aluminium stretcher automatic discharging device powered on, the microprocessor in the ECU (MCU single-chip microcomputer) carried out various initialization earlier according to program, and after initialization was finished, program entered duty.
After program entered duty, MCU is the signal of inquiring position detecting unit regularly.When device was not also loaded onto the aluminium strip, the test rod in the casing was sagging naturally under the effect of gravity, and test rod is lower than the strip lower position, and motor does not rotate.After device is loaded onto strip, test rod is attached under the aluminium strip on the vertical plane, MCU regulates program circuit according to the drawstring speed of Fig. 2, regulate motor speed, the following vertical plane that makes strip is fluctuation up and down lentamente near the strip lower position, and the strip average speed that keeps drawing in casing equals stretching-machine and draws the aluminium strip to go out the average speed of casing.After the strip in the strip dish pulled, the aluminium strip machine that is stretched subsequently in the casing was all pulled out,, the test rod in the casing is sagging naturally under the effect of gravity, and test rod is lower than the strip lower position, and motor stops operating.
A button is arranged on the device, and no matter where test rod is, as long as press the button, MCU rotates motor according to program with peak acceleration, and this is convenient to the device material loading.
In the casing of device a limit switch is arranged, after sagging the wearing of strip moved the test rod rising, touched limit switch, MCU turn-offed motor drive circuit, and sends contact signal, and stretching-machine is quit work.
In addition, MCU detects the drive current of motor in real time, and after motor current was greater than electromotor overload electric current certain hour, ECU sent light warning; When motor current during greater than short circuit current, MCU turn-offs motor drive circuit, and sends contact signal, and stretching-machine is quit work.
