For piler.Piler is the nucleus equipment of automatic stereowarehouse, and it is mainly used in the tunnel in High Level Rack warehouse
Orbiting, the carrying and access of goods can be achieved, complete out input work.
On walking in a horizontal state direction, lower railway in piler generally use is divided into day rail and track, and piler is automatically transported
Row is between upper lower railway.Motor drives road wheel rolls forward, and piler is transported under the guiding of horizontal guide sheave along track
OK.Piler walking in a horizontal state in place when, it is necessary to carry out precise positioning, positioning precision is ± 5mm.When piler needs to stop
When, the control system of piler can control movable motor to brake, and road wheel is produced friction with track, piler, which slides forward, to be subtracted
Speed, and then stop being positioned at the laser value position pre-set.
However, because the deadweight of piler is larger, height is higher, and in quick operation, inertia is bigger, in movable motor
In braking procedure, rocking for piler is very big, and locating effect is bad.Meanwhile often exceed and pre-set because inertia is too big
Laser value position, and the position of piler is not easily adjusted.Therefore auxiliary positioning mechanism is needed to aid in piler to carry out
Positioning.
At present, existing detent mechanism is mostly to hold upper rail by the friction plate of both sides, the effect of this mode brake hard
Fruit is obvious, but damage of the impact of braking moment to mechanism in itself is larger, and the friction plate contacted easily wears.
