Problems solved by technology

[0013] But, for example, if the interlayer distance of the determined stop floor is 4500mm, then the adjustment distance=(4500-3200)=+1300mm, the adjustment process of the interlayer distance cannot be completed during the period from deceleration to stop at the stop floor
[0014] That is, after the deceleration of the car frame starts to determine the stop floor, even if the inter-floor adjustment control section adjusts and controls the inter-car distance adjustment mechanism, if there is a large gap between the inter-floor distance of the departure floor and the inter-floor distance of the stop floor If it is different, there is also a problem that the adjustment control of the inter-floor distance cannot be completed during the period from the deceleration of the car frame to the stop.

no. 1 Embodiment approach

[0034] figure 1 It is a figure which shows the overall structure of each embodiment of the control apparatus of a double-deck elevator.

[0035] The control device of a double-deck elevator includes a double-deck elevator 10 and a control device 20 .

[0036] The structure of the double-deck elevator 10 includes: a car frame 13 suspended from one end of a main rope 12 mounted on the hoisting machine 11; The inter-car distance adjustment mechanism 15 that adjusts the relative distance between the upper and lower two car chambers 14a, 14b. 16 is a balance counterweight suspended at the other end of the main cable 12.

[0037] There are various configurations as the inter-car distance adjustment mechanism 15, but a specific example will be described here. The inter-car distance adjustment mechanism 15 includes a plurality of drive motors 15a, 15a, a plurality of screw drive bodies 15b, 15b, and a plurality of threaded pipe bodies 15c, 15c, which are provided on both end edges o...

no. 2 Embodiment approach

[0070] Since the control device for a double-deck elevator according to the second embodiment is the same as figure 1 The structure is the same, therefore, the description of the structure is omitted in order to avoid repetition.

[0071] The second embodiment is particularly different from the first embodiment in that figure 1 Another example of the advance moving inter-floor distance determination unit 241 shown, specifically, for Figure 4 The dotted box part (A), proceed as Figure 9 The extraction process of the interlayer distance shown in (A2).

[0072] Before the determination of the traveling direction of the car frame 13, the pre-moving inter-floor distance determination unit 241 acquires the car departure floor registered in the storage device 23 and the stop floor ( Step S31), then judge the traveling direction of the car frame 13 (step S32).

[0073] Here, when it is determined that the car frame 13 travels upward from the departure floor ("YES" in step S32), ...

no. 3 Embodiment approach

[0077] The control device for a double-deck elevator according to the third embodiment is the same as figure 1 The same structure, therefore, to avoid repetition, the description of its structure is omitted.

[0078] In the third embodiment, the point that is particularly different from the first embodiment is that it is another example of the pre-moved inter-floor distance determination unit 241. Specifically, in Figure 9 Add in the dotted box part (B) of Figure 11 A processing step S35 is shown. This additional processing step S35 is not only Figure 9 Append in , can also be appended in Figure 4 before step S23.

[0079] In processing step S35, the inter-floor distance of the predetermined non-stop floor is removed from each stop floor, and the process proceeds to step S23.

[0080] In this way, the maximum value and the minimum value can be extracted more accurately, and the pre-movement inter-layer adjustment distance can be calculated more accurately.

Abstract

The present invention relates to a control device of a double-deck elevator. The adjusting control of the inter-floor distance is ended before a lift car frame is stopped before a stopping layer, or the delay of the adjusting control of the inter-floor distance is restricted as the minimum. According to an embodiment, the control device of the double-deck elevator is provided with a storage device (23) which is used for storing inter-floor distance table, and the inter-floor distance table is used for storing inter-floor distances between lift cars stopping all floors; a beforehand mobile inter-floor distance determining part (241); a final mobile inter-floor distance determining part (243); and a multilevel inter-layer adjusting and control part, and the relative distance between the final lift cars can be adjusted and controlled through the lift car distance adjusting mechanism.

Description

[0001] This application is based on Japanese Patent Application No. 2011-044224 (filing date: March 1, 2011), and enjoys the priority of this application. This application incorporates this application in its entirety by reference. technical field [0002] Embodiments of the present invention relate to a control device for a double-deck elevator. Background technique [0003] In super high-rise buildings and the like, double-deck elevators capable of carrying out mass transportation by connecting a plurality of car rooms in the vertical direction are used. [0004] A double-deck elevator includes a car frame that slides up and down along a main guide rail in an elevator passage, and an upper car chamber and a lower car chamber that slide up and down along a sub-guide rail inside the car frame. Then, the car frame of the double-deck elevator is formed to be suspended on the cable that is hung on the drive pulley of the winch, and is moved up and down by the rotational force ...
