Embodiment
Fig. 1 is that elevator is monolithically fabricated legend.Elevator possesses control panel 2, motor 4, car 8, by the electricity in control panel 2
Terraced control device 3 controls the electric power supplied from three-phase alternating-current supply 1, and is supplied to motor 4, drives motor 4.Moreover,
By and the driving force supplied, making car 8 and balance weight 9 not shown from the pulley 5 of motor 4 is linked in via main rope 7
Liftway in lifted.Be mounted with to detect on the axle of pulley 5 direction of rotation of motor 4, car 8 position it is electronic
Machine R.E6 (motor encoder).
Speed controller rope 12 it has been coupled on car 8, speed controller rope 12 is set up in governor sheave 13.They and car
8 lifting is synchronous, and the speed controller rope 12 being coupled with car 8 moves, and rotates governor sheave 13.In governor sheave 13
Be mounted with axle according to the rotation amount of governor sheave 13 come detect the position of car 8, speed speed regulator R.E14 (speed regulators
Encoder).
Position detecting device 10 is installed in car 8, position detecting device 10 is arranged on lifting (not shown) by detection
The shutters 11 different in the superiors, orlop, intermediate laminates in passage, to detect the absolute position of car 8.In addition,
End layer detection means 15 is provided near orlop in liftway (not shown), is provided with foot in car
8 pour the buffer 16 protected during end layer.
Fig. 2 is the system pie graph example involved by present embodiment, is to be used to explain for losing absolute position
The figure for the action that the car 8 put safely travels towards orlop.By by the base of position operational part 18 in elevator control gear 3
In position detecting device 10 and motor R.E6 and speed regulator R.E14 step-by-step counting and the position operation values of computing, to slap
Hold the absolute position of car 8.If the power supply of control panel 2 is cut off, position computing can not be carried out, as long as so in power up
Position detecting device 10 does not detect the superiors or undermost shutter 11 during power supply, and elevator control gear 3 is judged as
To lose absolute position, in order to grasp absolute position, started running towards orlop.Now, as increasing the speed of car 8
The unit poured to buffer 16 is prevented while fast, uses end layer detection means 15.By the speed in elevator control gear 3
Operational part 19 carrys out speed when computing end layer detection means 15 detects end layer, and by comparing section 20 to velocity arithmetic value and storage
Speed setting value in storage part 17 is compared, if velocity arithmetic value is more than speed setting value, elevator control gear 3
Interior speed command portion 21 exports forced deceleration instruction to inverter 22, car 8 is rested in orlop.In addition, end layer detects
Device can use the device being made up of cam switch.
Stopped at due to car 8 also be present than end layer detection means 15 closer to undermost situation, so can also example
Speed is limited as set speed limit in two stages.Here, for speed limit, the speed faster than First Speed i.e. is set
Three speed.Car 8 is travelled before a certain set a distance is travelled using the First Speed as speed limit, certain having travelled certain
After distance, speedup to the third speed as speed limit.Now, for certain certain distance, by by comparing section 20 to by elevator
11 numbers of shutter or motor that position operational part 18 in control device 3 is detected based on position detecting device 10
R.E6 or speed regulator R.E14 step-by-step counting carry out the obtained position operation values of computing and the position being stored in storage part 17
Setting value is compared, according to comparative result come speed limit.
The flow chart illustration of present embodiment is shown in Fig. 3.Whether restored electricity after judging the dump of control panel 2
(S1), in the case where restoring electricity, judge whether position detecting device 10 detects the superiors or undermost shutter
11(S2)。
In the case where being not detected by, elevator control gear 3 is judged as losing absolute position, and speed limit is set into the first speed
Degree starts running (S3) towards orlop.If state (S4) downward driving that end layer is not detected by end layer detection means 15 is certain
Distance (S8), then make speed limit speedup to third speed (S9).If hereafter end layer detection means 15 detects end layer (S4), judge
Whether speed now has exceeded speed setting value (S5).In the case of more than for speed setting value, output forced deceleration refers to
Order, makes car 8 rest against orlop (S6).In the case of below for speed setting value, normally rest against in end layer (S7), electricity
Ladder recovers normal (S10).That is, after control device makes car emergent stopping, car is lifted certain distance with First Speed, rising
During drop certain distance by end layer detection means detect end layer and First Speed than it is prespecified it is fireballing in the case of,
Make car be decelerated to second speed to be lifted.In addition, it is not detected by during certain distance is lifted by end layer detection means
In the case of end layer, control device makes car be lifted with the third speed faster than the First Speed.
The present invention is not limited to above-described embodiment, and above-described embodiment is in order to be readily appreciated that to illustrate the present invention and detailed
Illustrate.It is not necessarily limited to possess illustrated entire infrastructure, each structure of embodiment, function, processing unit etc. are to them
Part or all be illustrated.For example, it is also possible to by the way of speed regulator R.E is installed to the axle of governor sheave or
It is connected to the mode of governor sheave.In addition, in the figure of embodiment, for clear explanation, it is illustrated that the electricity of 1: 1 canoe
Ladder, but can also apply to the elevator of 2: 1 canoes.
