The invention provides a kind of mechanical location of loom and detect bearing calibration, be used for detecting automatically the loom main shaft physical location, realize that the loom main shaft position is from dynamic(al) correction.
Below in conjunction with accompanying drawing specific embodiments of the invention are described further.
Referring to Fig. 1, this figure is that mechanical location of loom of the present invention detects the bearing calibration first embodiment flow chart.
The movement position of S10, detection Loom reed is determined the proal extreme position of described Loom reed.
Detecting the movement position of described Loom reed can realize by position sensor.Described position sensor installation site requires: the main shaft of described position sensor and described loom is perpendicular, and does not interfere with each other with described Loom reed.
Described position sensor can comprise two kinds: a kind of is analog quantity output type sensor, and the signal of analog quantity output type sensor output is a continually varying; Another kind is a digital quantity output type sensor, and the signal of digital quantity output type sensor output disperses.
Analog quantity output type signal of sensor is continually varying basically in effective range.Extreme value (as maximum Smax and minimum Smin) can appear in the continually varying process.Encoder angle during sensor output extreme value is α
0The encoder angle is α
0The time correspondence main spindle's be real main shaft 0 degree position.
Digital quantity output type signal of sensor is S
