Definitions

  • the present invention relates to an elevator installation with a lobby control panel and a control method for the elevator car of such an elevator installation using its lobby control panel.
  • An elevator system usually has an elevator car, which serves to move people within a building by moving the elevator car between floors (floors) of the building, and a car operating panel (COP) arranged in the elevator car or one outside the elevator car, For example, in a lobby, located at least one lobby control panel (LOP), with a requirement for an elevator car or a specification of where the elevator car should go, had to be entered using the LOP or COP.
  • LOP lobby control panel
  • a passenger must first request an elevator car with an LOP in a floor. When the elevator car lands at that floor, or if it just stops behind a landing door on that floor, the car door of the elevator car and the landing door are opened together. A shaft door is mechanically locked if there is no elevator car behind it. After entering the elevator car, the passenger can use the COP to enter further requests in order to instruct the elevator system to take him/her with the elevator car to a desired destination floor.
  • an elevator car of the elevator system When installing an elevator system in a building, an elevator car of the elevator system must learn the positions or heights of all floors of the building. The elevator car thus travels through all floors and stops on each floor so that it can find its stop position on the respective floor. In this case, it is necessary to first determine a rough stop position of the elevator car. Position calibration (fine adjustment) is then performed to accurately find a precise stop position of the elevator car so that the floor of the elevator car and the floor of each floor are as flat as possible or kept on a horizontal plane. However, in position calibration, it is difficult to easily control the exact position of the elevator car.
  • a technician must, as a rule, first inform a control device of the elevator system about a target stop position with regard to a floor. At least one target value for a stop position is assigned for each floor.
  • the control equipment is usually located in a machine room on the roof of a building or only in the specific one, such as the top floor. After that, the technician has to check on each floor whether the actual value corresponds to the target value of this stop position. If this is not the case, the technician must measure the deviation between the actual value and the target value. After that, he must either inform the control device about a new desired value or correct a positioning system of the elevator installation to eliminate the deviation.
  • Such method steps for setting a target value or for correcting a deviation can be repeated several times for each floor.
  • a door contact switch is provided on each shaft door of an elevator system and the car door of an elevator car, which is closed as long as the car door and the shaft door are closed and remains open as long as the two doors are open.
  • the door contact switches are connected in series within a safety chain of the elevator system. When the safety chain is closed as a whole, i.e. all door contact switches are also closed, the elevator car can be operated to move. If a door contact switch is opened or not properly closed, the entire safety chain is broken, which means that the elevator car can no longer run.
  • the door contact switch on a floor is only opened automatically when the elevator car lands on this floor during normal operation of the elevator system.
  • KNET switch contact unlocking shaft door switch
  • KTS door contact switch
  • an elevator system which comprises an elevator car and a lobby control panel (eg on each floor).
  • the elevator installation can be operated in a normal operating mode and a special operating mode.
  • the special operation mode is, for example, an installation mode or maintenance operation mode.
  • the lobby control panel has at least one control button.
  • the control button is a control element that is actuated, for example, by pressing, clicking or touching if the lobby control panel has a touchscreen.
  • the lobby control panel is designed in such a way that in the normal operating mode of the elevator system, the elevator car is automatically moved by pressing the control button for stopping on a floor on which this lobby control panel is located, and in the special operating mode the elevator car is manually controlled by pressing the control button for moving up and/or down can be.
  • KNET switch is no longer absolutely necessary, or at least in certain zones in the shaft.
  • this stop position can be confirmed, for example, via the lobby control panel and/or a control/positioning system of the elevator installation can be informed about this stop position.
  • a cumbersome scenario presented above, in which a technician has to walk back and forth between different floors to correct a target value or actual value of a stop position, can thus be avoided.
  • a method for controlling an elevator car of an elevator system with a lobby control panel is provided, with the lobby control panel comprising at least one control button.
  • the elevator system is operated between a normal operating mode and a special operating mode, in the normal operating mode the elevator car is automatically moved by pressing the control button for stopping on a floor on which this lobby control panel is located, and in the special operating mode the elevator car is moved by pressing the control button for moving up and down /or controlled downwards manually.
  • the elevator car in the special operating mode of the elevator system, can only travel a specific distance, which is typically to be measured in millimeters, by actuating the operating button. This distance can be set by the elevator manufacturer in production or by service personnel during installation or maintenance. If you press the control button once, the elevator car will move up or down a certain distance or distance, e.g. from 5mm to 10mm. As an alternative to this, the elevator car can run only during the operation of the control button, i.e. after releasing the control button or ending the operation, the elevator car stops immediately.
  • the elevator car can be moved continuously or in stages by pressing the control button
  • the travel speed of the elevator car increases or decreases with an increase or decrease in a force that is exerted to actuate the operating button.
  • the traveling speed of the elevator car can be divided into at least two steps, with a higher step being provided for a higher traveling speed and a lower step being for a lower traveling speed.
  • the lobby control panel has an up control button and a down control button, which are each provided for ordering an up or down trip with the elevator car in the normal operating mode.
  • the two control buttons are preferably each denoted by an arrow symbol pointing up and down.
  • the lobby control panel includes only a single control button, you can still control the direction of travel of the elevator car in the special operating mode of the elevator system by actuating force, number of operations or duration of operation that occurs when the control button is pressed.
  • a pressing force exerted on the operating button means a command for an upward or a downward movement.
  • a longer press of the control button means a ride up, and a shorter press of the control button means down.
  • the direction of travel can also be determined according to a number of consecutive actuations of the operating button. For example, a single click on the control button is intended for an upward movement, while a double-click is a downward movement. Compared to a press, a click operates a control button for a shorter time and/or applies less force.
  • the elevator car can be controlled to move by further actuating (e.g. pressing) the operating button.
  • the elevator car Before a safety circuit of the elevator system is put into operation, the elevator car can move independently of the switching state of the safety circuit. Therefore, for example, during the installation of the elevator system, the elevator car can be moved manually without any problems using the lobby control panel, no matter where the elevator car is located or whether the elevator car door or one of the shaft doors remains open.
  • the Safety circuit is already built and included to define a floor stop position for the elevator car, at least one door zone is given in the elevator shaft of the elevator system with respect to the respective floor. In such a door zone, the door contact switch (KTS) of the car door or the corresponding shaft door is bypassed or unlocked when the elevator car is, for example, completely. The elevator car can thus travel within the door zone despite the open car door and shaft door.
  • KTS door contact switch
  • the door zone can be called an unlocking zone.
  • a bridging switch can be fixed to the elevator car, for example.
  • the bypass switch can bypass the door contact switch of the shaft door or the car door, so that the shaft door and car door are decoupled from the door contact switch.
  • the entire safety circuit of the elevator installation remains electrically closed, even if the car door and a landing door are open.
  • calibrating or adjusting a floor stop position of the elevator car one can observe whether the floor of the elevator car and the floor of the floor are flat to each other and on a horizontal plane, allowing the elevator car to be precisely adjusted to an ideal stop position.
  • the door zone has a lower limit up to or below the floor of a floor and an upper limit up to or above the ceiling of this floor.
  • the lower limit is, for example, up to 25 cm below the floor of a floor and the upper limit is approximately up to 20 cm or 35 cm above the ceiling of that floor.
  • the area of a door zone can be delimited, for example, by a plurality of door zone magnets that are set exactly according to the position values calculated for them along the elevator shaft. For example, information about a current position of the elevator car can be determined using a magnetic tape extending vertically along the elevator shaft and a magnetic tape reading device attached to the elevator car.
  • the elevator car drives into a door zone, the car door and the corresponding shaft door are unlocked.
  • the elevator car can thus let passengers get off early at the destination floor and drive them away early from the start floor, as a result of which the travel time or the waiting time for passengers is shortened or optimized.
  • Fig.1 shows an elevator system according to the invention with a lobby control panel
  • FIG. 1 1 shows an elevator system 1 which has an elevator car 2 in a shaft 5 with a plurality of floors 10, a shaft door 11b being provided on each floor 10.
  • the elevator car 2 has a car door 11a, which normally always opens and closes together with a shaft door 11b at the same time.
  • a lobby operation panel 3 is placed on each floor 10 close to the landing door 11b.
  • the lobby control panel 3 comprises at least one control button 4, such as an up control button 4a and a down control button 4b, with the up control button 4a being provided for ordering an upward journey with the elevator car 2, while the down control button 4b is for a downward journey .
  • the two control buttons 4a and 4b are each denoted by an arrow symbol pointing up and down.
  • the lobby control panel 3 on the top or bottom floor includes only one control button 4 because the elevator car can only travel in one direction from such a floor.
  • two lobby control panels 3 are specifically on the right-hand side in the 1 enlarged extra shown, the upper two control buttons 4a, 4b includes, and the lower includes only one control button 4a.
  • the elevator system 1 In daily operation, the elevator system 1 is usually in its normal operating mode. Passengers can press or touch an operating button 4 on a floor 10, as a result of which the elevator car 2 receives instructions for entering this floor 10 and for the direction of travel (up or down) of a subsequent descent.
  • the elevator installation 1 is often placed in a special operating mode during its installation process or for maintenance. In the special operating mode, the elevator car 2 must not move automatically, but only move up and down manually by operating the control buttons 4a, 4b. In some elevator installations 1, however, it can be set that the elevator car 2 first automatically travels to a specific floor or stops in a specific position when switching to the special operating mode. After that, the elevator car 2 can only be manually controlled by the lobby operation panel 3 to move.
  • the elevator car 2 travels, for example, only a certain distance, for example from 5 mm to 10 mm. This distance can either be provided by elevator manufacturers in the manufacturing process or set by service personnel during on-site installation/maintenance work for the elevator system 1 . If the up control button 4a or the down control button 4b is pressed once, the elevator car 2 then moves up or down only for the specific distance accordingly. If the lobby control panel 3 is only provided with a single control button 4, a technician (not shown) in the special operating mode of the elevator system 1 can, for example, first click on the control button 4 once if he wants to move the elevator car up. If the elevator car 2 is to be moved down, he can double-click the operating button 4, for example.
  • the technician can manually control the elevator car 2 to move up or down by the operation button 4 accordingly.
  • Another way of determining a direction of travel using the single control button 4 would be to press the control button 4 for a longer period of time, such as pressing the control button 4 for a longer period of time to drive up, while pressing the control button 4 for a shorter period means a down drive.
  • a further possibility is to determine the direction of travel of the elevator car 2 by means of an actuating force, in which case pressing the operating button 4 more strongly means going up, and pressing it less means that going down is desired.
  • the technician can control the movement of the elevator car 2 continuously or step by step using the single or two control buttons 4 . If he presses the control button 4 with more force, the elevator car 2 moves correspondingly faster with the increase in force. If he reduces the force, the elevator car 2 then travels correspondingly more slowly.
  • the driving speed can be divided into two steps, namely a normal step and a fast or slow step.
  • the elevator system 1 After the elevator system 1 has been installed, it has to determine and then possibly configure its stopping positions for the elevator car 2 so that the elevator car 2 can stop precisely on each floor 10 when landing.
  • a target stop position is normally predefined and stored in a control system or positioning system 8 of the elevator system 1 or is currently specified on site. If a safety circuit (not shown) is not yet included for the elevator system 1, the elevator car 2 can be moved without any problems regardless of the switching state of the safety circuit, namely regardless of whether the car door 11a or a shaft door 11b remains open. Even if the safety circuit has already been completed, a technician always has an opportunity to observe the position of the elevator car 2 when controlling or positioning the elevator car 2 .
  • a door zone 9 is given in the elevator shaft 5 on each floor 10 so that a stop position or at least a rough stop position on the floor 10 is occupied for the elevator car 2 .
  • the door zone 9 is defined with a lower limit to the floor or up to about 35 cm below the floor of a floor 10 and with an upper limit to the roof or up to about 35 cm above the ceiling of this floor 10. If the elevator car 1 moves into such a door zone 9, the car door 11a and the shaft door 11b located in this door zone 9 are unlocked so that the safety circuit remains closed despite the open car door 11a and shaft door 11b.
  • the elevator car 2 can thus stop at least in the vicinity of a target stopping position on a floor 10 . Since the car door 11a and the shaft door 11b can remain open within such a door zone 9 while the elevator car 2 is moving, the technician can thus observe its current position when controlling the elevator car 2 and check whether the floor of the elevator car 2 and the floor of the floor 10 are flat to each other and on a horizontal plane, whereby the elevator car can be adjusted precisely up to its predetermined target stop position. But if this one If the target stop position is to be corrected, the technician can confirm the current position of the elevator car 2 and inform the control/positioning system 8 of this stop position, for example by pressing the up and down control buttons 4a, 4b simultaneously or pressing the single control button 4 either firmly and long (e.g. 3-5 seconds) or three times.
  • the technology described here can be used in an elevator system 1 with relatively little effort. Since positioning an elevator car 2 or assigning a stop position to a floor 10 is no longer necessary to measure the deviation of a current position of the elevator car 2 from a target stop position and then to inform a control system 8 of the elevator system 1 about it, installation or maintenance work for the elevator system 1 can be simplified and facilitated.
