The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
A kind of automatic correcting error device for conveying belt, in order to detect and export the running deviation value of load-transfer device, it comprises deviation detecting device, and deviation detecting device comprises: be arranged on the sideslip distance detecting mechanism 1 of load-transfer device both sides and sideslip distance changed into the change-over circuit of electric signal.
As shown in Figure 1, sideslip distance detecting mechanism 1 comprises base 11, base is provided with housing 12, housing 12 is provided with a rotating shaft 13, rotating shaft 13 is provided with a cam 14 to lower convexity, cam 14 is provided with straight up a push rod 15, push rod 15 can with cam 14 coaxial rotation, push rod 15 upper end sidewalls are pressed close to load-transfer device 5 edges; The base 11 of cam 14 belows is provided with an osed top hollow housing 16, hollow housing 16 inner close fitting bases 11 are provided with a pressure-strain sheet 17, pressure-strain sheet 17 tops are provided with a pressure spring 18, the pressure spring top is provided with a push rod 19, not under the sideslip state, paste mutually with cam 14 edges on push rod 19 tops at load-transfer device 5.
Sideslip takes place in load-transfer device 5, and load-transfer device 5 promotes push rod 15 and pivots its push rod corner
Become sinusoidal function relation with load-transfer device 5 running deviation value x:
Pressure-strain sheet 17 is constituted the dc balance electric bridge with precision resistance R2, R3, R4, and this millivolt level (mV) signal can take out, and as shown in Figure 2, establishes:
R
2□R
3□r
4□R，
Direct current bridge output signal then:
Vs is a bridge power supply in the formula, output voltage signal V and corner
Be directly proportional.Electric bridge connects signal conditioning circuit 21, and signal conditioning circuit 21 connects electric current loops 22, but signal conditioning circuit 21 filter out background noise and signal amplified after the belt deflection current signal of electric current loop 22 output 4-20mA.What it will be appreciated by those skilled in the art that is, the offset signals of output can be voltage signal fully, and does not influence enforcement of the present invention fully, and wherein signal conditioning circuit 21 and electric current loop 22 are prior art all, and are widely adopted, this just tired having stated.
As shown in Figure 3, electric current loop 22 connects controllers 3, and sends the sideslip current signals to controller 3, and the size of current signal is the 4-20 milliampere, its size by the sideslip of load-transfer device 5 apart from decision.Controller 3 connects the electrical motor 41 of deviation correction mechanism 4 and controls the angle that it starts and rotating shaft is rotated, and electrical motor 41 drives the correction parts.
As shown in Figure 4, the correction parts comprise: base 42, and base 42 is provided with rotating shaft 43, and rotating shaft 43 tops are provided with the deviation-adjusting carrier roller 44 of picking-up, support belt 5, and key is located in the rotating shaft 43 and drives the worm gear 45 that rotating shaft 43 is rotated; With worm gear 45 engaged worm 46, worm screw connects with electrical motor 41 by reducing gear 47.
Controller 3 receives the sideslip current signal, automatic guidance electrical motor 41 starts, and according to the size of current signal, it is the rotational angle apart from control motor 41 of load-transfer device 5 sideslips, make rotating shaft 43 rotate corresponding angle by worm screw 46, worm gear 45, and then drive carrying roller 44 with respect to load-transfer device 5 rotating certain angle, the back that turns an angle is as described below to the effect of load-transfer device 5:
When load-transfer device 5 no sideslips, 5 one-tenth 90 ° of degree of deviation-adjusting carrier roller 44 and load-transfer device, load-transfer device 5 during with the certain speed straight-line motion deviation-adjusting carrier roller 44 rotate, but do not produce transverse force (as shown in Figure 5).When load-transfer device 5 sideslips (as left avertence), deviation-adjusting carrier roller 44 is clockwise rotated one
The angle is so the friction force F between load-transfer device 5 and carrying roller 44
NUnder the effect, deviation-adjusting carrier roller 44 tries hard to make normal direction (N direction) motion (as shown in Figure 6) of load-transfer device 5 towards deviation-adjusting carrier roller 44, thereby produces load-transfer device 5 horizontal thrust F to the right
T1By this horizontal thrust F
T1, realize the correction of load-transfer device 5.In like manner, if load-transfer device right avertence then rotates counterclockwise one with deviation-adjusting carrier roller 44
Angle (as shown in Figure 7) produces load-transfer device 5 horizontal thrust F left
T1, realize the correction of load-transfer device 5.
According to the force analysis figure among Fig. 6, can obtain the horizontal correction power opposite with load-transfer device 5 sideslip directions:
In the formula, F is load-transfer device 5 pulling force.But in the correction process, deviation-adjusting carrier roller 44 will produce resistance F to load-transfer device 5
T2, the conveyer load is increased.
So corner
With
Can set up corresponding relation, controller 3 can be according to corner
Size (i.e. the size of the sideslip current signal of Jie Shouing) make corresponding angle of deviation-adjusting carrier roller 44 relative load-transfer device 5 deflections by electrical motor 41 and above-mentioned transmission device
This moment rectified a deviation power effect and return progressively of load-transfer device 5, running deviation value can progressively reduce, corresponding sideslip current signal also correspondingly reduces, controller 3 receives the sideslip current signal in real time, control motor rotating shaft counter-rotating, correction parts rotating shaft 43 also counter-rotatings, the angle that deviation-adjusting carrier roller 44 is rotated relative to load-transfer device 5
How therefore no matter also progressively reduce, load-transfer device 5 is got back to the normal position, and deviation-adjusting carrier roller 44 is also vertical with load-transfer device 5 again, and load-transfer device 5 sideslip can be adjusted it, in real time so that conveyer is in normal mode of operation.
Realize automatic deviation correction, deviation correction mechanism 4 should be arranged on converyor roller 51 around going into end, and therefore as Fig. 8, shown in Figure 9, the conveyer of unidirectional drive only need be provided with 2 deviation correction mechanisms 4, and the conveyer of bi-directional drive needs 4 deviation correction mechanisms 4.
