Definitions
- the invention relates to an elevator system with at least one shaft, in which at least two superimposed cars can be moved up and down, the shaft having a plurality of shaft doors and the cars each comprising at least one car door, and with a safety device for blocking the travel of the cars when open Shaft or car doors.
- the invention relates to a method for controlling an elevator system with at least one shaft, in which at least two superimposed cars can be moved up and down, the shaft having a plurality of shaft doors and the cars each comprising at least one car door, and wherein the cars are driven by means of a safety device can be blocked when the shaft or car door is open.
- Elevator systems are also known in which two cars can be moved up and down independently of one another in a shaft.
- a suitable mode of operation must ensure that both cars are braked and stop if only one car is to be loaded or unloaded, because otherwise, if the car and an associated shaft door were opened, one car would be due to the other car an emergency stop is triggered in the safety device used. This would result in a considerable risk of injury for the passengers in the other car. The stop of one of the cars thus impedes the travel of the other car. Ultimately, this has the consequence that the transport capacity of the elevator system is limited.
- the object of the present invention is to develop an elevator installation and a method for controlling an elevator installation of the type mentioned at the outset in such a way that the transport capacity of the elevator installation can be increased and the cars are as little as possible obstructed.
- the safety device has at least two independent safety circuits, each of which is assigned at least one shaft and / or car door, the travel of at least one car being able to be blocked by means of the safety circuits.
- the idea that a mutual obstruction of the cars can be reduced is incorporated into the invention by using at least two safety circuits which can block the travel of at least one car independently of one another.
- the control of the cars can be decoupled with regard to the state of the car and shaft doors, so that, if appropriate, only the travel of one car is blocked, while the other car can continue its journey undisturbed.
- it can be ensured that the opening of the car and landing doors when one car stops does not necessarily lead to an impairment of the travel of another car.
- the shaft has at least one shaft area, the shaft doors of which are assigned to only one safety circuit. If one of these landing doors is opened, only the movement of cars that are coupled to this safety circuit is blocked. The trips of cars that can be moved in different shaft areas can thus be decoupled in a simple manner.
- the shaft is divided in the vertical direction into a plurality of shaft areas, for example into an upper and a lower shaft area. If a shaft door is opened in the upper shaft area, this only results in the safety circuit assigned to this shaft door responding, so that the cars which are coupled to this safety circuit are blocked in their travel, but not the cars which are not coupled to this Have safety circuit.
- Such a configuration provides in particular the possibility of assigning different landing doors to the cars, so that opening or closing the landing doors which are assigned to one car does not result in a blockage of the travel of the other car.
- the shaft has at least one shaft area, the shaft doors of which are assigned to at least two safety circuits. If a shaft door is opened in such a shaft area, this results in the response of at least two safety circuits, which can each be coupled to different cars.
- At least one upper car can be moved in an upper shaft area having shaft doors and that at least one lower car can be moved in a lower shaft area having shaft doors, the car doors of the at least one upper car and the shaft doors of the upper shaft area are assigned to one or more first safety circles and the car doors of the at least one lower car and the shaft doors of the lower shaft area are assigned to one or more second safety circles.
- Such an embodiment has the advantage that within a shaft two cars can be moved independently of one another in an upper or a lower shaft area and do not interfere with their travel.
- At least one safety circuit forms a shaft door safety circuit, to which only shaft doors are assigned, whereby only the travel of cars can be blocked by means of the shaft door safety circuit, in whose operating area the assigned shaft doors are arranged.
- the "operating area" of a car is to be understood here as the area of the shaft which can be approached by a car. If the safety device has a shaft door safety circuit, this safety circuit only responds to the opening of the shaft doors and can then block the journey only from those cars in whose operating area the shaft doors assigned to this shaft door safety circuit are arranged.
- At least one safety circuit forms a car door safety circuit, to which only car doors are assigned, whereby only the travel of cars whose car doors are assigned to the car door safety circuit can be blocked by means of the car door safety circuit.
- the at least one car door safety circuit only responds to the opening of the assigned car doors, while the opening of a shaft door has no influence on the car door safety circuit.
- each car door safety circuit is assigned only the car doors of one car. If a car door is opened, the result of such a configuration is that only the car door safety circuit assigned to this car responds, while the car door safety circuits of the other cars remain unaffected by this.
- each car is assigned a single car door safety circuit and a single shaft door safety circuit.
- the car door safety circuit assigned to each car only monitors the state of its own car doors and the assigned shaft door safety circuit can be designed in such a way that it only responds to the opening of the shaft doors arranged in the operating area of this car.
- the car door and landing door safety circuits assigned to each car have monitoring elements, for example switch contacts, which are connected in series with one another.
- the series connection can ensure, for example, that the travel of the car is blocked as soon as one of its car doors or one of the shaft doors located in its operating area is opened.
- a separate shaft door monitoring element is arranged on each shaft door for each car that approaches this shaft door.
- the operating areas of the cars that can be moved in a shaft are separated from one another, so that no operating area has shaft doors that can be approached by another car.
- it can be advantageous if the operating areas of the cars have an overlap such that at least one of the landing doors can be approached by both a first and at least a second car.
- each car can be blocked by a shaft door safety circuit to which at least one shaft door is assigned, which is arranged in the operating area of only this one car, and at least one shaft door which is located in the operating area of this one car and at least one other car is arranged.
- the opening of the landing door can take place shortly before reaching the level position of the elevator car with the landing door, for example already at a distance of about +/- 0.3 m, provided the elevator car has a speed of less than about 0 , 8 m / s.
- the shaft door is usually opened under the effect of Opening movement of the car door, ie when holding a car, at least one door of the car is coupled to the landing door, so that the landing door is also opened with the elevator car door. Due to the possibility of overriding the monitoring of this shaft door, the movement of the other cars within the shaft is not impaired when one car stops.
- the monitoring of the opening and closing state can preferably only be overridden by those shaft doors which are arranged in the operating area of at least two cars.
- the monitoring of landing doors, which are only arranged in the operating area of a single car, cannot be overridden in such a configuration of the elevator system. This provides the possibility of checking the response of the safety circuit coupled to a car by moving to and opening a shaft door, the monitoring of which cannot be overridden.
- the monitoring of the opening and closing status of the shaft and car doors is preferably carried out with the aid of monitoring elements of the safety device, each of which interacts with a shaft or car door.
- Switching contacts can be used as monitoring elements, for example, which can be actuated by opening the associated shaft or car door.
- a touch-sensitive or a non-contact actuation of the switch contacts can be provided.
- the shaft and car doors are mechanically coupled to the switch contacts, alternatively or additionally, an inductive or capacitive coupling can be provided or a coupling by means of infrared or light radiation. It is expedient if the monitoring elements of shaft doors, the monitoring of which can be deactivated, can be rendered ineffective, for example bridged, by means of a bridging unit.
- the bridging unit can be arranged on the shaft door or on one or more cars. It is particularly advantageous if the bridging unit has an activation element which can be actuated by a car stopping at the associated shaft door. If a car enters the area of the shaft door with the intention of opening the door, it can actuate the activation element of the bridging unit to bridge the monitoring elements assigned to the shaft door.
- the activation member can be actuated by touch or without contact. It can be provided, for example, that the activation member is designed as a magnetic switch which can be actuated by moving the car closer together.
- this comprises an installation control unit, which is preferably coupled to input elements arranged outside the shaft for the input of a destination call by a passenger.
- the destination of the elevator car can be predetermined for the elevator control, and it is particularly advantageous here if the bypass units used to override the monitoring of the shaft doors can be activated by the elevator control. This enables the bridging units of a landing door to be activated when the elevator control causes the elevator car to stop at this landing door.
- the bridging units can be started by actuating their activation members by means of a car. It is particularly advantageous here if the bridging units can only be activated when their activation members are actuated if they are simultaneously acted upon by a control signal provided by the system controller.
- the bridging units are thus designed in two channels, with both channels simultaneously having to be effective in order to override the monitoring of the respectively assigned landing door.
- a first channel of the bridging unit is controlled by the respective activation element which interacts with a car stopping in the area of the shaft door, while a second channel of the bridging unit is controlled by the system controller. Only in the event that a control signal from the system controller is present and the activation element is actuated by the elevator car, the monitoring of the landing door is deactivated.
- each car is connected to a separate voltage supply unit for supplying power to the drive and control elements of the cars. It is advantageous if the car door and shaft door safety circuits of each car, i.e. the car door and shaft door safety circuits in which the respective car is integrated, are connected to the respective voltage supply unit of the car, with shaft door safety circuits with shaft doors that are arranged in the operating area of at least two cars, to which the voltage supply unit of only one of the cars involved can be connected.
- the shaft door safety circuits, the associated shaft doors of which are located in the operating area of several cars. are automatically connectable to the voltage supply unit of a given car, provided that the car is in operation.
- the shaft door safety circuits, the shaft doors of which are arranged in the operating area of a plurality of cars are connected to a preferred voltage supply unit, which is the voltage supply unit of one of the cars approaching the shaft doors.
- a preferred voltage supply unit which is the voltage supply unit of one of the cars approaching the shaft doors.
- the connection is only available when this car is in operation. If this car is taken out of operation, the shaft door safety circuits in question are automatically connected to the voltage supply unit of another of the cars moving to the shaft doors.
- the design of the elevator system according to the invention ensures that a non-operational opening of shaft doors results in an obstacle to the travel of all cars in the shaft, in the operating area of which the open shaft door lies.
- opening landing doors is not the only safety-related event that can affect the travel of a car.
- the elevator system according to the invention can have further safety-relevant switching elements with the aid of which the operating states of the elevator system can be monitored.
- the elevator system can influence the travel of at least one of the cars, for example, slow it down or accelerate it, if two cars are inadmissibly close to one another.
- a shaft monitoring circuit is assigned to each car, by means of which the travel of the car can be blocked depending on the state of safety-relevant switching elements, at least one switching element being associated with a bridging element for inactivating the switching element, the movement being triggered when a first car with an actively assigned bridging element is moving at least one second car can be blocked.
- Such an embodiment of the elevator system according to the invention is characterized in that at least one safety-relevant switching element can be rendered ineffective, for example bridged, by means of a bridging element, but it is ensured that when the first car is moving with an active bridging element, the movement of at least one second car can be blocked.
- a safety-relevant switching element for example a proximity switch
- a proximity switch can be deliberately made ineffective in order to deliberately bring two cars closer together, an appealing proximity switch forming a safety-relevant switching element, but this can be deliberately deactivated, for example bridged. If the two cars move away from each other again, the bridging should be overridden again.
- the invention provides that when a first car is in motion with an active associated bridging element, the travel of at least one second car can be blocked.
- the blockage of the second car can be lifted by means of the elevator control. This gives, for example, the possibility of removing the blockage within the area of a certain shaft door, so that the second car can be aligned flush within the area of the shaft door, but cannot leave the area of the shaft door.
- the invention also relates to a method for controlling an elevator system with at least one shaft, in which at least two superimposed cars can be moved up and down, the shaft having a plurality of shaft doors and the cars each comprising at least one car door, and wherein the Movement of the cars can be blocked by means of a safety device when the shaft or car door is open.
- such a method according to the invention provides that the travel of each car is blocked separately depending on the opening and closing states of its car doors and all shaft doors and depending on the position of all along the shaft movable cars.
- the method according to the invention is characterized in particular in that after checking the individual car door states, the individual car positions and the shaft door states, the travel of the individual cars is enabled or blocked. For example, there is an upper car in an upper shaft area, while a lower car is in a position occupies a lower shaft area, the travel of the lower car can also be released if a shaft door in the upper shaft area is open, provided that this shaft door is outside the operating area of the lower car. However, if it is found that a shaft door is opened within the operating range of the lower car, the travel of the lower car is blocked if the opening of this shaft door is not carried out by the upper car during operation.
- the method according to the invention has the advantage that the travel of the cars which can be moved within the shaft is hampered as little as possible and the transport capacity of the elevator system can thereby be increased.

- the shaft 12 has at least one shaft door 44, which in the embodiment shown comprises two door leaves.
- the opening and closing status of the shaft doors 44 is monitored by respectively assigned monitoring means which have electrical contacts.
- Each shaft door 44 additionally has locking means, for example hook bolts, with signaling contacts.
- the monitoring means and blocking means are collectively referred to below as switching elements 45.
- the electrical contacts of the switching elements 45 are closed when the associated shaft door 44 is closed and locked, the contacts are open when the associated shaft door 44 is not closed or is not locked.
- the interconnection of the electrical contacts of all switching elements 45 of all shaft doors 44 forms a shaft door security unit 47 which is explained in more detail below and shown in FIG. 2.
- Each car 14 and 16 is assigned a separate voltage supply unit 49 and 50, which takes over the voltage supply of all control and drive components assigned to the respective car 14 and 16.
- the electric drive motors 24 and 25 as well as the brakes 28 and 29 of each car 14, 16 are supplied with electrical energy by the respectively assigned voltage supply unit 49 or 50.
- the voltage supply unit 49 is in electrical connection via an electrical supply line 52 and a first current path 53 with the drive motor 24 and via the electrical supply line 52 and a second current path 54 with the brake 28 of the upper car 14, between the electrical supply line 52 and the a first contact block 55 and a drive control 56 are connected to the first current path 53, and a second contact block 57 is connected between the electrical supply line 52 and the second current path 54.
- the voltage supply unit 50 of the lower car 16 is connected via an electrical supply line 60 and a first current path 61 to the associated drive motor 25 and via the electrical supply line 60 and a second current path 62 to the associated brake 29, between the electrical supply line 60 and the first current path 61, a first contact block 63 and a drive control 64 are connected, and between the electrical supply line 60 and the second current path 62, a second contact block 65 is connected.
- the first and second contact blocks 55, 57 and 63, 65 assigned to each car 14 and 16 can be electrically actuated by a contactor 67 and 69 assigned to the respective car 14 and 16, respectively.
- the first and second contact blocks assigned to the upper car 14 55, 57 form the contactor contacts of the contactor 67
- the first and second contact blocks 63, 65 assigned to the lower car 16 form the contactor contacts of the contactor 69.
- the voltage supply for the contactor 67 is provided via a safety chain 71 assigned to the upper car 14, via which the contactor 67 is connected to the voltage supply unit 49 of the upper car 14.
- the safety chain 71 is formed by a shaft monitoring circuit 72 assigned to the upper car 14, the output contacts 74 of a shaft door safety circuit 75 assigned to the upper car 14, explained in more detail below, and the car door safety circuit 37.
- the shaft door monitoring circuit 72, the output contacts 74 and the car door Safety circuit 37 are connected in series to one another.
- the shaft monitoring circuit 72 assigned to the upper car 14 is configured in a manner known per se, it contains all the safety switches assigned to the upper car 14 and to be integrated into a safety loop, such as emergency limit switches, safety switches, buffer switches and the like.
- the switching elements 35 of the car doors 34 of the upper car 14 and the switching elements 45 of all the shaft doors 44 are not included in the shaft monitoring circuit 72.
- a current flow from the voltage supply unit 49 to the contactor 67 only occurs when all the electrical contacts of the safety chain 71 involved in the current flow are closed. The current flow is interrupted as soon as only one contact involved in the current flow is open. If all contacts of the safety chain 71 are closed, the brake 28 of the upper car 14 is supplied with electrical energy by the voltage supply unit 49 via the electrical supply line 52 and the second current path 54, so that the brake 28 is opened.
- the drive motor 24 of the upper car 14 is supplied with electrical energy by the voltage supply unit 49 via the electrical supply line 52 and the first current path 53, which can thus be rotated in order to move the car 14.
- An interruption in the flow of current via the safety chain 71 to the contactor 67 has the result that the first and second contact blocks 55, 57 are opened and the power supply to the brake 28 and the drive motor 24 is thereby interrupted. This means that the drive motor 24 is no longer available electrical drive energy and that the brake 28 is applied, so that the drive shaft of the drive motor 24 is braked and the car 14 comes to a stop.
- the contactor 69 assigned to the lower car 16 is connected to its voltage supply unit 50 via a safety chain 78 of the lower car 16.
- the safety chain 78 is configured in a manner corresponding to the safety chain 71; it has a shaft monitoring circuit 79 known to the person skilled in the art, which is connected in series to output contacts 80 of a shaft door safety circuit 81, which is explained in more detail below and is assigned to the lower car 16, and to the switching elements 40 of the car door safety circuit 42 of the lower car 16.
- the shaft monitoring circuit 79 is designed in a manner corresponding to the shaft monitoring circuit 72. It contains all the safety switches assigned to the lower car 16 and to be integrated into a safety loop, for example emergency limit switches, safety switches, buffer switches and the like. However, the switching elements 40 of the car doors 39 of the lower car 16 and the switching elements 45 of all the shaft doors 44 are not included in the shaft monitoring circuit 79.
- a current flow from the voltage supply unit 50 to the contactor 69 only occurs when all the electrical contacts of the safety chain 78 involved in the current flow are closed.
- the current flow is interrupted as soon as only one contact involved in the current flow is open. If there is a current flow, the assigned first and second contact blocks 63, 65 are closed by the contactor 69, so that the brake 29 is connected via the electrical supply line 60 and the second current path 62 to the voltage supply unit 50 and thereby opens and the drive motor 25 opens the electrical supply line 60 and the first current path 61 are supplied with electrical energy and are thereby rotated in order to move the lower car 16.
- the speed of the drive motor 25 can be regulated in a manner known per se by the drive control 64, which can be designed, for example, in the form of a frequency converter.
- the drive control 56 assigned to the upper car 14 enables a corresponding control of the rotational speed of the drive motor 24 and can also be designed as a frequency converter. If the current flow from the voltage supply unit 50 via the safety chain 78 to the contactor 69 is interrupted, the contacts of the first and second contact blocks 63 and 65 are opened, ie the power supply to the drive motor 25 and the brake 29 is interrupted. This has the consequence that the brake 29 is applied and the drive shaft of the drive motor 25 is braked and consequently the lower car 16 comes to a stop.
- the elevator system 10 has a system controller 85, which is connected via a signal line 86 to a rotary pulse generator 87, which is held on the drive shaft of the drive motor 24 of the upper car 14 in a rotationally fixed manner and provides the system controller 85 with travel pulses, from which the system controller 85 in the usual way can determine the position of the upper car 14.
- the system controller 85 is in electrical connection with a rotary pulse generator 89, which is held in a rotationally fixed manner on the drive shaft of the drive motor 25 of the lower car 16 and provides the system controller 85 with travel pulses from which the system controller 85 determines the position of the lower car 16 in can determine in the usual way.
- the system controller 85 is electrically connected via a first control line 91 to a first bypass circuit 92 which is assigned to the upper car 14 and which is connected in parallel to the car door safety circuit 37 and can be controlled by the system controller 85.
- a second bridging circuit 93 is used, which is connected to the system controller 85 via a second control line 94.
- the bridging of the car door safety circuits 37 and 42 by means of the first and second bridging circuits 92 and 93 makes it possible to open the car doors 34 and 39 when entering a stop in the unlocking area of this stop, even before the car 14 and 16 the Has reached the flush level of the respective stop, so that the car 14 or 16 with the car doors 34 and 39 already open can reach the flush level.
- opening the car doors 34 and 39 has the consequence that the car door safety circuit 37 and 42 is opened.
- the interruption of the current flow to the contactor 67 or 69 can, however, be prevented by means of the first or second bypass circuit 92 or 93, provided the control system 85 provides a control signal depending on the position of the upper and lower car 14, 16 determined in each case becomes.
- Activation of the bypass circuit 92 or 93 means that its electrical contacts are closed and the bypass is thus active.
- an open car door safety circuit 37 or 42 no longer leads to an interruption in the current flow to the associated contactor 67 or 69.
- the associated bypass circuit 92 or 93 is not activated by the system controller 85, its contacts are open and are closed the bridging is not active.
- the locations of the cars 14 and 16 within the shaft 12 are known to the system controller 85 on the basis of the travel pulses provided by the respective rotary pulse generators 87 and 89, and the bridging circuits 92 and 93 are only activated when the respective car 14 and 16 is in the Unlocking area of the stop to be approached.
- the bridging circuits 92, 93 can also be used Output contacts 74 and 80 of the shaft door safety circuit 75, 81 assigned to the respective car 14 and 16 are bridged by the bridging circuits 92 and 93 not via a connecting line 96 which only bridges the assigned car door safety circuit 37 or 42, Rather, they are connected to the respective safety chain 71 or 78 via a connecting line 97, which is shown in dashed lines in FIG. 1, the connecting line 97 not only allowing the car door safety circuit 37 or 42 to be bypassed, but also the output contacts of the respective landing door Safety circuit 75 or 81.
- the elevator system 10 is shown in a highly schematic manner with a total of eleven stops, the lowest stop being located on the ground floor of a building and bearing the reference number 100, the next stop is located on the first floor and is given the reference number 101.
- the other stops are assigned 102, etc., so that the stop on the tenth floor has the reference number 110.
- the stops on the third to sixth floors are not shown in FIG. 2, but the design of the corresponding stops and the electrical wiring of the corresponding components in these stops is identical to the stops 102 or 107 explained below.
- FIG. 2 the design of the corresponding stops and the electrical wiring of the corresponding components in these stops is identical to the stops 102 or 107 explained below.
- the stop 100 located on the ground floor can only be reached from the lower car 16 and the two uppermost stops 109 and 110 of the ninth and tenth floors can only be reached from the upper car 14, while the intermediate stops 101 up to 108 from both cars.
- the operating area of the lower car 16 thus extends over the stops 100 to 108
- the operating area of the upper car 14 extends over the stops 101 to 110, and the entire shaft 12 can be in an upper shaft area with the stops 109 and 110 and in a common shaft area with the stops 101 to 108 and into a lower shaft area with the stop 100 can be divided.
- the stops of the lower and upper shaft areas can only be approached by one of the two cars 14, 16, while the stops in the common shaft area can be reached by both cars.
- the switching elements 45 of all the shaft doors 44 in their entirety form a shaft door safety unit 47.
- This has a shaft door safety circuit 75, which is assigned to the upper car 14, and one Landing door safety circuit 81, which is assigned to the lower car 16.
- the shaft door safety circuit 75 assigned to the upper car 14 is connected to a switching unit 112 which has the output contacts 74, and the shaft door safety circuit 81 of the lower car 16 is connected to a switching unit 114 with the output contacts 80.
- the shaft door safety circuit 81 of the lower car 16 is formed by a series connection of the switching elements 45 of the stops 101 to 108 and the stop 100 located on the ground floor, while the switching elements 45 of the stops 109 and 110 located on the ninth and tenth floors are not in the shaft door. Safety circuit 81 of the lower car 16 are involved.
- the shaft door safety circuit 75 of the upper car 14 is formed by a series connection of the switching elements 45 of the stops 101 to 110, while the switching elements 45 of the stop 100 located on the ground floor are not integrated in the shaft door safety circuit 75 of the upper car 14.
- the shaft door safety circuits 75 and 81 are supplied with voltage via a common supply line 116 and a common return line 117 connected to the switching units 112 and 114, which can be connected to the voltage supply unit 49 of the upper car 14 or the voltage supply unit 50 of the lower one via contact blocks 119 and 120 Car 16 are connectable.
- the contact blocks 119 and 120 can be controlled by a contactor 122, which is connected to the voltage supply unit 49 of the upper car 14. If the upper car 14 is in operation, its voltage supply unit 49 is active.
- the contactor 122 is supplied with electrical energy and the controls two contact blocks 119 and 120 in such a way that the common supply line 116 and the common return line 117 of the two shaft door safety circuits 75 and 81 are in electrical connection with the voltage supply unit 49. If, on the other hand, the upper car 14 is not in operation, its voltage supply unit 49 is switched off. As a result, the contactor 122 is not supplied with electrical energy. The contact blocks 119 and 120 then assume such a switching position that the supply line 116 and the return line 117 are in electrical connection with the voltage supply unit 50 of the lower car 16. The shaft door safety circuits 75 and 81 are therefore only supplied with electrical energy by a single voltage supply unit 49 or 50, the voltage supply unit 49 of the upper car 14 preferably being used if this car 14 is in operation.
- the current flow through the shaft door safety circuit 75 assigned to the upper car 14 takes place from the feed line 116 starting from the switching elements 45 of the stops 101 to 108 connected in series, which can be approached by both cars 14 and 16, and via the switching elements 45 of the stops 109 and 110, which can only be approached from the upper car 14, and then via a current path 124 to the switching unit 112 and from there via the return line 117 to one of the two voltage supply units 49 or 50.
- the current flows through the shaft door safety circuit 81 assigned to the lower car 16, starting from the feed line 116, via the switching elements 45 of the stops 101 to 108 accessible by both cars 14, 16 and then via a current path 125 to the switching elements. elements 45 of the lowest stop 100 and then via the switching unit 114 to the return line 117.
- switching units 112 and 114 are supplied with electrical energy via the respectively assigned landing door safety circuits 75 and 81, their output contacts 74 and 80 are closed. If the power supply to the switching units 112 or 114 is interrupted, the respective output contacts 74 and 80 are opened.
- the switching elements 45 of the shaft doors 44 which are arranged in the area of the stops 101 to 108 and can be approached by both cars 14 and 16, are each assigned a separate bridging unit 127 arranged in the area of the respective stop, with the aid of which the respective switching element 45 is ineffective made, namely can be bridged electrically.
- the identically configured bridging units 127 each have two control channels, in that they are electrically connected via a first input line 128 to a fork-shaped magnetic switch 129 arranged in the area of the respective stop 101 to 108 and connected to a control element 132 of the system controller 85 via a second input line 130 are.
- the bridging units 127 each have a first contact row 134 and a second contact row 135, the switching positions of which are always identical.
- Each first row of contacts 134 is electrically connected to a feedback element 138 of the system controller 85 via an output line 137, and the switching element 45 of the shaft doors 44 assigned to the respective bridging unit 127 can be bridged via the second row of contacts 135.
- a switching element 45 can only be bridged by means of the associated bridging unit 127 if both the magnetic switch 129 arranged in the area of the respective stop in the shaft 12 is actuated and a control signal is provided by the control element 132 via the second input line 130.
- the magnetic switch 129 is actuated by means of switching lugs 140 which are fixed to the cars 14 and 16 and can be designed, for example, in the form of a sheet metal strip.
- the locations of the magnetic switch 129 in the shaft 12 in the area of the stop assigned to the respective magnetic switch 129 on the one hand and the location of a switching flag 140 on the cars 14 and 16 on the other hand are selected so that a magnetic switch 129 can only be actuated if one of the two Cars 14, 16 are located in the unlocking area of the stop assigned to the respective magnetic switch 129.
- the two contact rows 134 and 135 are only closed when both control channels of the corresponding bridging unit 127 are activated simultaneously. Both contact rows 134 and 135 are open if only one channel or neither of the two channels is controlled.
- a closed row of contacts 135 of a bridging unit 127 bridges the switching elements 45 of all landing doors 44 of the assigned stop.
- the contact row 134 always has the same switching position as the contact row 135. It serves to report back the switching position of the contact row 135.
- the system controller 85 is always informed about the switching position of all the bridging units 127 and can do this by reporting the switching positions of the contact rows 134 Use information to control the flow of cars 14 and 16 and intervene to correct the flow of traffic in the event of a fault.
- the bridging units 127 in connection with the traffic flow of the cars 14 and 16 is described below by way of example for the entry of the car 16 into the stop 101 located in the first upper floor: the car 16 is initially outside the unlocking area of the stop 101 and is approaching it Stop with the intention of stopping at stop 101.
- the car 16 has already reduced its speed, namely to a speed less than 0.8 m / s, that the entry into the stop 101 can be released by the system controller 85, and the car 16 is located in the immediate vicinity of the unlocking area Stop 101, namely at a distance of about 0.3 m from the flush level of this stop, then the system controller 85 controls the first channel of the associated bridging unit 127 via the second input line 130.
- the switch lug 140 dips into the fork of the magnetic switch 129, whereby the magnetic switch 129 controls the second channel of the same bridging unit 127 via the first input line 128. If both channels of the bridging unit 127 assigned to the stop 101 are activated, then the two contact rows 134 and 135 of the bridging unit 127 are closed. The closed contact row 135 bridges the switching elements 45 of all shaft doors 44 of the stop 101. The closed contact row 134 reports via the output line 137 to the feedback element 138 of the system controller 85 that the switching elements 45 have been bridged in the stop 101. The system controller 85 now opens the shaft door 44 at stop 101.
- Opening the shaft door 44 at stop 101 does indeed cause the electrical contact of the switching element 44 to be opened, but this does not lead to an interruption of the connection due to the active bridging by means of the contact row 135 of the bridging unit 127.
- Control of the switching units 112 and 114 of the two shaft door safety circuits 75 and 81, ie their output contacts 74 and 80 remain closed. Despite the open shaft door at stop 101, the journeys of the two cars 14 and 16 are not affected.
- the associated magnetic switch 129 is no longer actuated by the switching flag 140 of the lower car 16, i. H. the second channel of the bridging unit 127 is no longer activated, so that both contact rows 134 and 135 of this bridging unit 127 are opened and consequently the bridging of the switching elements 45 in the stop 101 is canceled. If one of the landing doors 44 of the stop 101 is still open due to a malfunction, this leads to an immediate stop of both cars 14 and 16.
- the control of the first channel of the bridging unit 127 assigned to the stop 101 is ended by the system controller 85 before the start of the journey, so that both contact rows 134 and 135 of this bridging unit 127 are opened and thus the bridging of the switching elements 45 this stop 101 is canceled.
- the result of this is that a new journey of the lower car 16 starting from the stop 101 can only start with the shaft doors 44 of this stop 101 closed.
- No bridging units 127 are installed in the stops 100 and 109, 110, which can only be approached by one car 16 or 14, respectively. As a result, the switching elements 45 of the shaft doors 44 cannot be bridged in these stops 100, 109 and 110. However, due to the interconnection of the shaft door safety circuits 75 and 81 that are used, the entry into these stops 100, 109 and 110 and the opening of the shaft doors 44 of these stops 100, 109 and 110 thereby only have an effect on the shaft door safety circuit 75 or 81, which is assigned to the respective incoming car 14, 16.
- bypass circuit 92 Since the bypass circuit 92 is only effective, as described above, when the upper car 14 is in the unlocking area of the assigned stop into which it is to enter, this measure has no safety-relevant disadvantages.
- the opening of the switching door 44 only interrupts the actuation of the switching unit 114 of the shaft door safety circuit 81. This leads to the opening of the output contacts 80.
- the shaft door safety circuit 75 of the upper car 14 remains unaffected by this and its output contacts 74 remain closed.
- An immediate stop of the lower car 16 when entering the bus stop 100 can be prevented by using the connecting line 97 instead of the connecting line 96, as shown in broken lines in FIG. Since the bypass circuit 93, as already mentioned, is only effective when the lower car 16 is in the unlocking area of a stop into which it is to enter, this measure has no safety-relevant disadvantages.
- a single shaft door safety unit 47 is used with switching elements 45 of all shaft doors 44 connected in series, and the shaft door safety circuits 75 and 81, each associated with a car 14 and 16, respectively, cover a portion of the series connection of the switching elements 45.
- the use of two shaft door security units that are electrically separated from one another can also be provided, each comprising a shaft door security circuit that is assigned to a car.
- a separate switching element 45 and 46 can be arranged on each shaft door 44 for each car 14, 16 approaching this shaft door 44, the switching elements 45 and the switching elements 46 each forming their own series connection and thus a separate shaft door safety circuit.
- both the switching elements 45 and the switching elements 46 shown in dashed lines in FIG. 1 are each assigned a bridging unit, which is electrically only is connected to the respective switching element 45 or 46, but which can be activated by all the cars 14 and 16 approaching the respective shaft door 44.
- a bridging unit which is electrically only is connected to the respective switching element 45 or 46, but which can be activated by all the cars 14 and 16 approaching the respective shaft door 44.
- FIG. 3 A second embodiment of an elevator installation according to the invention is shown schematically in FIG. 3 and is designated overall by reference numeral 150.
- This is largely identical in design to the elevator system 10 explained above with reference to FIGS. 1 and 2.
- the same reference numerals are therefore used in FIG. 3 as in FIGS. 1 and 2.
- the foregoing explanations are used in full Referred.
- the upper car 14 has a proximity switch 152, the switch contacts 153 of which are integrated in the shaft monitoring circuit 72 of the safety chain 71 assigned to the upper car 14, the switch contacts 153 being connected in series to other, known switch contacts of the Safety circuit 72 are switched.
- the proximity switch 152 is actuated via a switching roller 154, which is held on the outside on the upper car 14 and which comes into contact with a button 155 when the upper car 14 approaches the lower car 16, which button on a car has a car ceiling 156 of the lower one Car 16 protruding spacer 157 is set. If the upper car 14 approaches the lower car 16 so far that the button 155 of the lower car 16 actuates the switching roller 154, the proximity switch 152 of the upper car 14 is actuated, its switching contacts 153 being opened. This has the consequence that the power supply to the contactor 67 of the upper car 14 is interrupted and consequently the travel of the upper car 14 is blocked.
- the button 155 thus forms a collision prevention direction, with the aid of which collisions between the two cars 14 and 16 can be prevented.
- an invalidation element in the form of a bridging module 160 is used in the elevator system 150 in the form of a bridging module 160 with a normally open contact 161 and a normally closed contact 162.
- the bridging module 160 is held at a predetermined point within the shaft 12, at which a strong approach of the two cars 14 and 16 should be allowed, the normally open contact 161 being connected in parallel with the switch contacts 153 of the proximity switch 152.
- the bridging module 160 has a switching plunger 163 which can be actuated by a switching curve 164 fixed on the outside on the upper car 16. If the bridging module 160 is actuated by actuating the switching plunger 163 through the switching element curve 164, this has the consequence that the make contact 161 closed and the normally closed contact 162 is opened.
- the break contact 162 is integrated in the safety chain 78 of the lower car 16 and connected in series with the car door safety circuit 42. Together with the car door safety circuit 42, it can be bridged by the second bypass circuit 93.
- the proximity switch 152 despite the use of the proximity switch 152, a targeted approach of the upper car 14 to the lower car 16 can take place, with an impairment of the travel of the upper car 14 being prevented since the switch contacts 153 of the proximity switch 152 are bridged by the closed make contact 161.
- the simultaneous opening of the opener contact 162 ensures, however, that when the upper car 14 approaches the lower car 16 deliberately, the travel of the lower car is blocked, since the opener contact 162 is integrated into the safety chain 78 of the lower car 16.
- the floor distance between the stop 100 located on the ground floor and the stop 101 located on the first floor can be chosen to be so small that in the event that the lower car 16 is in the stop 100 , the proximity switch 152 is actuated when the upper car 14 enters the stop 101, but this actuation does not impair the traffic flow.
- the location of the bridging module 160 within the shaft 12 of the elevator system 150 is selected such that when the car 14 enters the stop 101, the switching curve 164 actuates the switching plunger 163 of the bridging module 160, so that the normally open contact 161 then closes the switching contacts 153 of the proximity switch 152 bridges and at the same time the normally closed contact 162 assumes its open switching position. Leaves the upper car 14 the stop 101 and if the bridging module 160 remains actuated due to a fault, the break contact 162 remains in its open position.
- the lower car 16 can still move within the stop 100, for example readjust as long as both the car safety circuit 42 and the break contact 162 of the lower car 16 bypasses the car safety circuit 42 by actuating the bypass circuit 93 but that the lower car 16 cannot leave the stop 100 with the intention of moving to another stop, since in this case the system controller 85 no longer actuates the bridging circuit 93 of the lower car 16, as a result of which the bridging is canceled and thus the opened normally closed contact 162 interrupts the current flow to the contactors 69. This results in an immediate stop of the lower car 16. The travel of the upper car 14 is unaffected by this.
