Description

The present invention relates to a method for operating an elevator system with at least two elevator shafts and with cars that can be moved in the elevator shafts, and to such an elevator system.

State of the art

Skyscrapers and buildings with a large number of floors require complex elevator systems in order to manage all transport processes as effectively as possible and to be able to transport individual passengers to their destination floor as quickly as possible without long waiting times.

So-called shaft-changing multi-cabin systems, such as those sold by the applicant as MULTI® elevator systems, for example, have proven to be particularly effective DE 10 2014 224 323 A1 are described. A shaft changing multi-car system comprises a plurality of cars that can be moved in a group of elevator shafts. The cabs can not only be moved back and forth vertically in the individual elevator shafts, but also horizontally between the individual elevator shafts.

If a large number of cabs are moved in an elevator shaft and these cabs in principle carry out stop stops on any floor as required, there is a risk of jamming in the elevator shaft. A cabin that makes a stop can thus hinder or stop the other cabins.

The present invention seeks to improve the effectiveness of elevator systems.

Disclosure of the invention

According to the invention, a method for operating an elevator system and a correspondingly operated elevator system with the features of the independent claims are proposed. Advantageous embodiments are the subject of the subclaims and the following description.

The elevator system according to the invention has at least two elevator shafts and cars that can be moved in the elevator shafts. The elevator shafts of the elevator system are divided into two different categories of shafts, in which the cars are moved in different ways or make stops. In a first shaft category, cabs in at least one elevator shaft may only make stop stops on predetermined floors and may not make stop stops on floors located between these predetermined floors. In a second shaft category, cabs are allowed to make stop stops in at least one elevator shaft on any or individual floors. Furthermore, cars can switch between the at least one elevator shaft in the first shaft category and the at least one elevator shaft in the second shaft category.

In the elevator shafts of the first shaft category, floors are fixed a priori, in which the cars may stop and which cars may start. Correspondingly, floors are specified a priori, which may not be started in the first shaft category or in which no stops may be made. In particular, these floors are predefined independently of a current need or independently of destination floors entered by passengers.

Cabs can thus be moved quickly in the first shaft category over the floors between the given floors. In particular, the elevator shafts of this first shaft category represent express elevator shafts, in which cabins can be moved quickly over a large number of floors. In particular, congestion of cabins can be avoided in the first shaft category, since individual stops cannot be made on every floor. Cabins can therefore be moved in the first shaft category in particular with high efficiency and a high transport rate.

In contrast to this, the cabs in the elevator shafts of the second shaft category can in principle approach each floor or make a stop on each floor. In particular, “on demand” is selected depending on the current need in which specific individual floors stop stops are carried out, in particular depending on the current demand or depending on the destination floors entered by passengers. In the second shaft category, cabins can make stops on the same floor or on different floors, depending on individual needs. The booths in the second shaft category can expediently also approach the individual floors between two adjacent predetermined floors. The cabins in this second shaft category thus have the advantage that they can move to each floor in particular and can conveniently carry out transport operations to any floor, but there is a risk of congestion if individual stops are made Any floor may be approached from cabins.

The invention combines the advantages of these two different concepts to move cabins. The cabins in the first shaft category can be used in particular as express cabins and can be moved quickly and efficiently across a large number of floors. The cabins in the second shaft category are used in particular as local cabins in order to be able to move to any floor between the given floors. The cabins can expediently switch flexibly between the different elevator shafts. This combination of the first and second shaft categories provides a particularly effective way to carry out transport processes with high efficiency and to improve a handling capacity of the elevator system. For example, a car can change from an elevator shaft in the second shaft category to an elevator shaft in the first shaft category in order to overtake cars in the second shaft category, and can later switch back to an elevator shaft in the second shaft category in order to move to an individual floor.

In order to switch between the elevator shafts, a car can in particular be moved horizontally in a connection area between these elevator shafts or in a shaft running horizontally between these elevator shafts. The invention is particularly suitable for a so-called MULTI® elevator system from the applicant, in which a plurality of cars can be moved independently of one another in one or more shaft sections by means of a linear motor drive. Such an elevator system with several cars that can switch between shaft sections is, for example, from US Pat DE 10 2014 224 323 A1 known.

In order to carry out a transport process from a starting floor, for example a lobby, to a specific individual floor, which is not one of the predetermined floors, a car can be moved quickly from the starting floor, for example initially over a large number of floors in the first shaft category. The car can then switch to an elevator shaft of the second shaft category in order to move to the specific individual floor in this elevator shaft.

Cabs can preferably switch between the elevator shafts of the first shaft category and the second shaft category on at least one of the predetermined floors, advantageously on all predetermined floors. In order to take up the example above, i.e. to carry out a transport process from a starting floor, for example the lobby, to any particular floor that is not one of the predetermined floors, a cabin is first, for example, from the lobby in the first shaft category to one of the predetermined floors in proceed in the vicinity of the specific target floor, in particular to the specific floor that is closest to the specific target floor. There, the cabin expediently changes from the first shaft category to the second shaft category and is moved there to the specific destination floor.

Advantageously, there is a predetermined number of floors between the predetermined floors, advantageously a constant number of floors. For example, the predetermined number can be between five and ten floors. This predetermined number of floors in particular allows different areas or zones to be defined in which cabins in the first shaft category are not allowed to make stops and in which the corresponding number of floors can be covered quickly.

Advantageously, cabins in the first shaft category always make a predetermined stop on the given floors. In particular, as long as they are traversed in an elevator shaft of the first shaft category, all of the cars therefore carry out a predetermined stop on all of the predetermined floors that they pass. The specified floors are therefore always approached in the first shaft category or a stop is always carried out on these specified floors, in particular regardless of current demand or independent of destination floors entered by passengers. In contrast to this, the cabins in the second shaft category make stop stops expediently “on demand” or depending on current demand, in particular depending on current demand or depending on destination floors entered by passengers.

The cars in the elevator shafts of the first shaft category therefore collectively carry out the same stops, one after the other, one after the other on the same floors. In particular, in each elevator shaft in the first shaft category, cars can be moved at the same or at least essentially at the same speed. In particular, the predetermined stops of the individual booths have the same length or at least substantially the same length and are expediently carried out at the same time or essentially at the same time, so that the individual cars in each elevator shaft of the first shaft category move synchronously with one another or at least substantially synchronously with one another. If all the cabins in the first shaft category carry out stop stops in a corresponding manner on the same floors, the cabins can in particular be moved with high efficiency and transport rate and in particular congestion of cabins can be avoided.

According to a particularly preferred embodiment, in the first shaft category, cabins are moved upwards in at least one first elevator shaft and downwards in at least one second elevator shaft. Likewise, in the second shaft category, cabins are advantageously moved upwards in at least one first elevator shaft and downwards in at least one second elevator shaft. Thus, in these first elevator shafts of the first and second shaft categories, cabins in particular are moved exclusively upwards and in the second elevator shafts of the first and second shaft categories in particular only downwards. This at least one first elevator shaft of the first shaft category represents in particular an express elevator shaft for cabins upwards, in which cabins are quickly moved upwards over a large number of floors. Correspondingly, the at least one first elevator shaft of the second shaft category represents in particular an express elevator shaft for journeys downwards.

Cabs on at least one of the predetermined floors can preferably switch between the at least one first elevator shaft of the first shaft category and the at least one first elevator shaft of the second shaft category. As an alternative or in addition, cars in at least one of the predetermined floors can preferably switch between the at least one second elevator shaft of the first shaft category and the at least one second elevator shaft of the second shaft category. In this case, cabins can expediently only change between elevator shafts with the same direction of travel. In addition, cabins can preferably be able to switch between all elevator shafts in at least one of the predetermined floors, regardless of the directions of travel.

Advantageously, cabs in a third shaft category may optionally make stop stops in at least one elevator shaft in each case on predetermined floors and no stop stops in each case on floors lying between these predetermined floors. As an alternative, cabins in this third shaft category may stop at any floor in the at least one elevator shaft. In particular, in this case, depending on the current traffic situation or the current transport operations to be carried out, a decision can be made as to whether stop stops are only carried out in the third shaft category on predetermined floors or whether individual stop stops are also carried out on any individual floors in addition to the predetermined floors. Depending on requirements, cabins in this third shaft category can be used as express cabins or local cabins.

In the third shaft category, cabins are advantageously moved downwards in the at least one elevator shaft. Such a third shaft category is particularly useful in buildings in which journeys downward are mainly carried out into an entrance floor or lobby floor, in which passengers leave the building, as is usually the case, for example, in hotels or apartment buildings.

In the third shaft category, cabins in the at least one elevator shaft are preferably allowed to stop only on one entrance floor. For example, in the course of an individual stop in the second shaft category, a cabin on any floor can accommodate passengers who want to leave the building. The car is then moved into an elevator shaft of the third shaft category and is moved there to the entrance floor without stopping again. In this case, cabins in the third shaft category in the at least one elevator shaft may advantageously also make stop stops on any floors, if necessary, in particular to accommodate additional passengers who want to leave the building on the entrance floor.

According to a particularly preferred embodiment, cars are moved upwards in the at least one elevator shaft in the first shaft category, upwards and / or downwards in the at least one elevator shaft in the second shaft category and downwards in the at least one elevator shaft in the third shaft category. This version is particularly suitable for buildings in which journeys upwards are mainly carried out from an entrance floor or lobby floor and journeys downwards mainly into this entrance or lobby floor, as is often the case, for example, in hotels or residential buildings. In this case, cabins in the first and second shaft categories are used in particular to move passengers from the entrance floor to theirs To transport the destination floor. The cabins in the third shaft category are expediently used to transport passengers down to the entrance floor so that they can leave the building.

It goes without saying that the elevator system can also comprise further components, for example rails or guide rails arranged in the individual elevator shafts, and drives for moving the cars, which can be designed in particular as linear drives.

Further advantages and refinements of the invention result from the description and the accompanying drawing.

It goes without saying that the features mentioned above and those yet to be explained below can be used not only in the combination specified in each case, but also in other combinations or on their own without departing from the scope of the present invention.

The invention is shown schematically in the drawing using an exemplary embodiment and is described below with reference to the drawing.

Detailed description of the drawing

In 1 A preferred embodiment of an elevator system according to the invention is shown schematically and with 100 referred to, which is set up to be operated according to a preferred embodiment of a method according to the invention. The elevator system 100 has four elevator shafts 111 . 112 . 121 . 122 on in which a variety of cabins 150 is proceeded.

In a first shaft category 110 allowed cabins 150 in the elevator shafts 111 and 112 only in given floors 101 . 102 . 103 . 104 Carry out stop stops. The given floor 101 is, for example, an entrance or lobby floor. For example, every tenth floor can be specified as such a floor. The given floor 102 can be, for example, the tenth floor, the floor 103 for example that 20 , Floor and the floor 104 for example that 30 , Floor. Cabins are allowed on the floors between these specified floors 150 in the elevator shafts 111 and 112 the first shaft category 110 do not make stops.

In a second shaft category 120 allowed cabins 150 in the elevator shafts 121 and 122 Make individual stop stops on any floor, especially on all floors.

In the first shaft category 110 become cabins in the elevator shaft 111 only move upwards and in the elevator shaft 112 exclusively down. In the second shaft category 120 become cabins in the elevator shaft 121 only move upwards and in the elevator shaft 122 exclusively down.

The given floors 101 . 102 . 103 . 104 still represent transfer floors, in which cabins 150 between all elevator shafts 111 . 112 . 121 . 122 can switch.

An example is considered below to three passengers from the entrance floor 101 to be transported to different target floors. For example, a first passenger would like to go from the entrance floor 101 to that 10 , Floor, a second passenger from the entrance floor 101 to that 12 , Floor and a third passenger from the entrance floor 101 to that 28 , Floor.

The three passengers enter the entrance floor 101 initially the same cabin. This car is then in the elevator shaft 111 the first shaft category 110 from the entrance floor 101 to the first given floor 102 , that is 10 , Move the stick. On this given floor 102 the cabin stops and the first passenger can leave the cabin.

The cabin then changes on the specified floor 102 in the elevator shaft 121 the second shaft category 120 , There the cabin is in that 12 , Move to the floor and carry out an individual stop, during which the second passenger leaves the cabin.

Based on this situation, the third passenger can enter the 28 , Floor to be transported. Depending on the current traffic situation and position of the other cabins can be decided which option is chosen.

Either the cabin will continue in the elevator shaft 121 the second shaft category 120 up to that 28 , Move to the floor and make an individual stop there. This option is useful when in the elevator shaft 121 above the 12 , Make few or no more stops on the floor.

Alternatively, the cabin is up to the given floor 103 process, there changes back into the elevator shaft 111 the first shaft category, is in this up to the specified floor 104 procedure, changes there to the elevator shaft 122 the second shaft category 120 and is going down this from the given floor 104 , so from that 30 , Floor until that 28 , Move to the floor and make an individual stop there. This option is useful when in the elevator shaft 121 above the 12 , Make several additional stops on the floor, which are in the elevator shaft 111 the first shaft category 110 can be overhauled.

In 2 Another preferred embodiment of an elevator system according to the invention is shown schematically and with 200 referred to, which is set up to be operated according to a preferred embodiment of a method according to the invention. The elevator system 100 has three elevator shafts 211 . 221 . 231 on in which a variety of cabins 250 is proceeded.

In a first shaft category 210 allowed cabins 250 in the elevator shaft 211 only in given floors 201 . 202 . 203 . 204 Carry out stop stops. The given floor is analogous to the description above 201 for example an entrance or lobby floor, the given floor 202 for example the tenth floor, the given floor 203 for example that 20 , Floor and the given floor 204 for example that 30 , Floor.

In a second shaft category 220 allowed cabins 250 in the elevator shaft 221 Make individual stop stops on any floor, especially on all floors.

In a third shaft category 230 allowed cabins 250 in the elevator shaft 231 Optionally, only carry out a predetermined stop on the entrance floor and, if required, also individual stop stops on any floor.

In the elevator shaft 211 the first category 210 cars are only moved upwards in the elevator shaft 221 the second category 220 both up and down and in the elevator shaft 231 the third category 230 exclusively down.

The given floors are analogous to the description above 201 . 202 . 203 . 204 continue to be designed as transfer floors, in which cabins 250 between all elevator shafts 211 . 221 and 231 can switch.

Such an embodiment of the elevator system 200 lends itself, for example, if transport operations are mainly carried out down to the entrance floor. An example is considered below to get two passengers from different floors into the entrance floor 201 to transport. For example, a first passenger would like from that 25 , Floor in the entrance floor 101 arrive and a second passenger from the 15 , Floor.

For example, a cabin is selected for this, which is currently in the 21 , Floor in the elevator shaft 221 the second shaft category 220 located. This cabin is in this elevator shaft 221 to that 25 , Move to the floor and carry out an individual stop, during which the first passenger enters the cabin.

Thereupon the cabin of the 25 , Floor to the given floor 204 , so in the 30 , Floor, move and change there from the elevator shaft 221 the second shaft category 220 in the elevator shaft 231 the third shaft category 230 , There the cabin is down to that 15 , Move to the floor and make an individual stop to pick up the second passenger. Thereupon the cabin is further down into the entrance floor 201 moves and performs a predetermined stop there, on which the passengers can leave the cabin.
