Technical Field

The present invention relates to an elevator system.

Background

DE 102014220966 a1 discloses an elevator system in which a plurality of cars are operated cyclically in a circulating pattern, similar to a bucket elevator. Unlike conventional bucket elevators, each car is driven independently of the other cars and can therefore stop at any stopping point independently of the other cars. A repositioning unit is provided to reposition the car from a vertical lane to a horizontal lane so that the car can thereby be repositioned between different vertical lanes.

German patent application 102018205592.0 discloses a method for assembling rails in an elevator system of the above-mentioned type. In this way, the following facts are taken into account: the repositioning units and the fixed rails located between the repositioning units must always be accurately aligned relative to each other. For this purpose, the track has, in particular, a length compensation.

EP 3318526 a1 discloses an elevator system in which a car can be moved between two vertical hoistways within a transfer station. The car is guided in the hoistway by means of side rails. In this case the guide rails are always arranged on opposite sides of the car. By means of such a rail guide, the center of gravity of the car is arranged substantially between the guide rails. To allow the car to move laterally between the hoistways, the car moves with portions of the side rails between the hoistways. The laterally movable part of the side rail is received in a laterally displaceable car together with the car (paragraph [0035] in EP 3318526 a1 and "elevator carriage rail 172" in fig. 3). However, if the car is displaced between hoistways, the portion of track connected thereto is not available for another car to travel vertically through the transfer station.

Disclosure of Invention

The problem addressed by the present invention is to provide an improved elevator system. This problem is solved by an elevator system and method according to the main claims; embodiments are the subject of the dependent claims and the description.

The elevator system according to the invention comprises: at least one first lane oriented in a first direction, in particular vertically, at least one second lane oriented in a second direction offset therefrom, in particular horizontally, and an optional third lane oriented in the first direction, in particular parallel to the first lane. The elevator system further comprises at least one car, in particular a plurality of cars. The guide rails are configured to guide the car along the first lane and the second lane and optionally the third lane, and the repositioning unit repositions the car from the first lane to the second lane and/or from the second lane to the first lane. The guide rails include a backpack guide rail configured to guide the car at least when the car is in the repositioning unit and/or at least when the car enters the repositioning assembly and/or at least when the car is removed from the repositioning assembly. The guide rails also include side guide rails configured to guide the car when the car is not in a repositioning unit, particularly when the car is traveling in a vertical lane between two repositioning units.

The combined use of side rails and backpack rails allows certain advantages to be utilized. The backpack guide rail allows for a simple, safe, quick repositioning of the car, wherein the space required for the repositioning unit is small. Furthermore, the repositioning unit can be used immediately after the repositioning action for receiving or for continuously transporting another car, since the guide rails do not move transversely to the car away from the lane. On the other hand, during long and fast vertical driving and braking actions, the side rails are characterized by low roller wear and low vibrations transmitted through the rollers, since the weight force of the car is transmitted substantially centrally, in particular in the middle or substantially in the middle.

In one embodiment, a side rail gap is provided which is arranged between two side rails arranged next to one another, in particular arranged vertically to one another, when viewed in the direction of the first lane. This allows the car to be transferred in the lateral direction through the gap. Thus, the side rails do not impede lateral movement of the car in the area of the repositioning assembly. To this end, in one embodiment, the gap height of the side rail gap is greater than the height of the car.

In one embodiment, an overlap region is provided. The cars located in the overlap region are guided by both the at least one backpack guide rail and also by the at least one side guide rail. In this way, a safe switching of the car between the side guides and the rucksack guide rails is created.

In one embodiment, the car is constantly guided by the backpack guide rails and/or the side guide rails when the car moves in the first lane and the second lane and when the car moves in the repositioning unit. This means that in the above-mentioned position, one of the above-mentioned guide rails always ensures a minimum guidance, thereby improving the safety of the installation.

In one embodiment, a repositioning assembly is provided for repositioning the car from a first lane oriented in a first direction to an adjacent third lane also oriented in the first direction. Such a repositioning assembly comprises: at least two repositioning units arranged in the second lane; and a guide rail along the second lane, which is disposed between the two repositioning units. During the transfer between the two repositioning units, the car is guided only by the rucksack guide rails.

In the method for relocating a car from a first lane to a second lane and/or a third lane in the above-mentioned elevator system, the following method steps are provided:

-guiding the car along a side guide rail (21V) along the first lane,

-transferring the car from the side rail to the rucksack rail,

-transferring the car to a second lane, wherein the car is guided by a rucksack guide rail. In one embodiment, the car is transferred to the third lane.

In one embodiment, the car is guided by a backpack guide rail when the car is transferred to the third lane.

In one embodiment, the car is transferred from the backpack guide rail to the side rail and guided along the side rail along the third lane.

In one embodiment, the car travels through the repositioning unit, particularly during vertical travel. In this case, the car is initially guided along the side rails along the first lane; then, the car is transferred from the side rail to the backpack rail; then, the car is further guided along the backpack guide rails along the first lane; then, the car is transferred from the backpack guide rail to the side guide rail; the car is then guided further along the side rails along the first lane.

Such transport therefore involves the switching of the rail system. By this transport, the car does not stop, in particular between guiding the car along the side rails of the first lane and intermediate transfer to the rucksack rails of the car. The car preferably continues to travel at a constant speed as it passes the repositioning unit.

Detailed Description

Fig. 1 and 2 show parts of an elevator system 1 according to the invention. The elevator system 1 comprises a plurality of lanes 2H, 2V along which a plurality of cars 5a-5H are guided.

A plurality of vertical lanes 2V (in this case, for example, two) are oriented in a first direction along which the car 5 can move between different floors. The horizontal lane 2H is disposed between two vertical lanes 2V, and the cars 5 can move within floors along the horizontal lanes, respectively. Further, the horizontal lane 2H connects the two vertical lanes 2V to each other. The horizontal lane 2H is therefore also used to transfer the car 5 between the two vertical lanes 2V, in order to achieve, for example, modern bucket elevator operation. Further horizontal branches 2H of this type connecting two vertical guide rails to each other are provided in the elevator system 1. Further, an additional vertical lane 2V, not shown, may be provided.

Guide rails 21V, 22H, 22D for guiding the cars are provided along the lanes 2V, 2H. For this purpose, the car has guide rollers 51, for example, which guide rollers 51 are depicted in fig. 1 for guidance on the rails 21V.

The rails include backpack rails 22V, 22H, 22D. The backpack guide rails are disposed on a common side of the car. In this case, the car 5, in particular the center of gravity of the car 5, is arranged in a constantly protruding manner. Gravity is transferred to the backpack rail by introducing a bending moment.

The backpack guide includes a fixed vertical backpack guide 22V oriented along a vertical lane. The backpack guide rails include a fixed horizontal backpack guide rail 22H oriented along the horizontal lane 2H.

The car can be repositioned from one vertical lane 2V to another vertical lane 2V by means of the repositioning assembly 3.

The repositioning assembly 3 includes two repositioning units 30 and a horizontal backpack guide rail 22H. The car 5 can be transferred between the vertical backpack guide rails 22V and one of the horizontal backpack guide rails 22H by the repositioning unit 30, respectively. In this case, the repositioning unit 30 includes a rotatable backpack guide rail 22D.

All guide rails are mounted at least indirectly in the hoistway wall 20. The elevator system thus far corresponds essentially to the description given in WO 2015/144781 a1 and also in DE 102016211997 a1 and DE 102015218025 a 1.

The guide rails also include vertical side guide rails 21V. Two vertical side guide rails 21V are attached to opposite sides of the car 5, respectively. The center of gravity of the car 5 is arranged substantially between the vertical side rails (as viewed in the y-direction). It is obvious that, especially for design and/or load reasons, the center of gravity of the car 5 is at least not exactly arranged between the two vertical side rails 21V (centered in the x-direction with respect to the vertical side rails). Such a vertical side guide rail 21V has a variety of isolation uses in conventional elevator systems.

The invention is characterized in that the vertical side guide rails 21V and the vertical backpack type guide rails 22V are alternately arranged along the vertical lane 2V. Thus, the vertical backpack rail 22V is arranged in the area of the repositioning unit 30; the vertical side rail 21V spans the area between the two repositioning units 30.

The vertical side rail 21V is broken in the area of the repositioning unit 30. To this extent, the repositioning units 30 are each arranged in the side rail gap 21L. Therefore, the vertical side guide rail 21V does not obstruct the lateral transfer of the car 5.

The clearance height H21L of the side rail clearance 21L is greater than the height H5 of the car. Therefore, during the lateral transfer action, the car fits through the side rail gap 21L.

In the area of the repositioning assembly 3, the use of a rucksack guide rail facilitates rapid repositioning of the car 5 between the vertical lanes 2V. As explained in the introduction to EP 3318526 a1, in this case it is not necessary to use a swing car which receives the car during relocation between lanes.

In the following, different positions in the track guidance of the car are described by means of fig. 3 a-3 e. The cars 5a-5e depicted here correspond to the cars 5a-5e shown in figure 2 in their respective positions. For the sake of simplicity, only the car 5 and those tracks guiding the car in this position are schematically depicted in fig. 3 a-3 e. The associated rollers are not shown for clarity.

In the position shown in fig. 3a, the car 5a is located in the area between the two repositioning units 30. The car 5a is guided only by the vertical side guide rails.

In the position shown in fig. 3b, the car 5b is located in an overlap region 24, in which overlap region 24 the vertical side guide rail 21V and the vertical rucksack guide rail 22V are arranged in an overlapping manner in the direction of travel. The car 5b is guided by both the vertical side rail 21V and also by the vertical rucksack rail 22V to promote safe and comfortable transport from the side rail 21V to the rucksack rail 22V.

In the position shown in fig. 3c1 and 3c2, the car 5c is located in one of the repositioning units 30, and therefore also in the region of the side rail gap 31L. The car 5c is guided only by the rotatable rucksack guide rail 22D.

In the position shown in fig. 3c1, the rotatable backpack rail 22D is oriented vertically and is thus aligned with the fixed vertical backpack rail 22V (not shown). The car 5 can be transferred between the vertical backpack guide rails 22V and the rotatable backpack guide rails 22D.

In the position shown in fig. 3c2, the rotatable backpack guide rail 22D is oriented horizontally and is thus aligned with the horizontal backpack guide rail 22H. The car 5 can be transferred between the horizontal backpack guide rails 22H and the rotatable backpack guide rails 22D.

In the position shown in fig. 3d, the car 5d is located in the horizontal lane between the two repositioning units 30. The car 5d is guided only by the horizontal backpack-type guide rails 22H.

In the position shown in fig. 3e, the car 5e is likewise located in the overlap region 24. The car 5b is guided by both the vertical side guide rail 21V and the vertical backpack guide rail 22V to promote safe and comfortable transport from the vertical backpack guide rail 22V to the vertical side guide rail 21V.

Once the car leaves the rotatable backpack guide rails along the horizontal rails 22H during repositioning, the rotatable rails 22D may be rotated back to the vertical orientation again. The next car can then be directed to the repositioning unit, for example, to perform the next repositioning action or for vertical transport.

Once the car leaves the rotatable backpack guide rails along the vertical tracks 22V, 21V after repositioning, the rotatable track 22D can be rotated back to the horizontal orientation again. The next car can then be directed to the repositioning unit, for example, to perform the next repositioning action or for horizontal transport.

The overlap area 24 also allows for significantly increased tolerances during assembly of the vertical rails. The vertical rails are not in line over the entire length of the lane (i.e., hoistway height). If the overlap area 24 is of sufficient size, thermally induced length changes in the vertical rails or the settlement of buildings still have virtually no effect.
