5 front end of rail is inserted into the hollow portion 333 of guide rail hole location reference block 33.
(6) after being inserted in place, starting laser emitter 31 emits light beam.The light beam of transmitting passes through 332 He of benchmaring hole
Guide rail rail bottom fixation hole 52c, is received by laser pick-off target 32, by analysis laser pick-off target 32 be imaged integrated degree and
The light intensity for receiving light beam judges whether the fixation hole 52c of guide rail rail bottom complies with standard and departure degree.
(7) after the completion of detecting, cage guide 5 is transported to the guide rail hole location of the other side by 2 inverted running of longitudinal conveying device
At detection device 3, repeat step (6)
(8) after the completion of detecting, supporting mechanism lifting device 423 starts, and makes supporting block 421 that cage guide 5 be driven to rise.Branch
Bracer driving device 422 starts, and drives cage guide 5 to push to 41 direction of turnover mechanism supporting block 421.Swing arm 411 is being put
State in a vertical shape under the driving of arm swing driving device 412.
(9) after in place, supporting mechanism lifting device 423 resets, and makes supporting block 421 that cage guide 5 be driven to decline, makes rail bottom
Inner end 52b offsets with guide rail rib 411a.Rear-swing arm 411 it is dynamic to backswing, due to the effect of inertia and gravity, lead elevator
Rail rail bottom 52 is in contact with swing arm 411.
