Definitions

  • the invention relates to a method for controlling the distance separating a vehicle and the vehicle preceding it in the running direction at the output of a clocking section of a continuous-running cable transport installation.
  • the invention also relates to a continuous-running cable transport installation for carrying out the method, in which the cable supports vehicles staggered according to a predetermined timing, said installation having in at least one loading / unloading station a timing section associated with timing means comprising a means for selectively driving the vehicles, controlled by a control unit for controlling the distance separating, at the output of the timing section, a vehicle and the vehicle preceding it in the direction of travel.
  • the field of the invention relates to all types of transport installation ensuring the movement of vehicles through a towing cable, for example chairlifts or gondolas.
  • Controlling the distance separating, at the output of a timing section of a continuous-running cable transport installation, a vehicle and the vehicle preceding it in the direction of travel, is necessary to arrange the vehicles along the cable at a predetermined timing.
  • the timing is chosen in such a way that the vehicles have an equal time interval between them. This time interval is identical at the station and along the cable.
  • the minimum value of the distance between two vehicles is for example conditioned by the necessary physical distance between these two vehicles to avoid their docking station, especially when their trajectory has turns.
  • timing section along the transfer circuit of at least one of the embarkation / disembarkation stations, but which requires at its output a regular rate of movement of the vehicles, regardless of their frequency input.
  • This timing section makes it possible to overcome unavoidable delays that occur during operation (braking and acceleration conditions differ from one vehicle to another, variable loading of vehicles, variable climatic conditions, etc.).
  • the control unit operates in two distinct operating modes.
  • the first mode called “stop-gap”
  • the control unit drives the drive means of the vehicles along the timing section so as to reposition any vehicle offset from its theoretical position, to said theoretical position.
  • the second mode of operation automatically activated when the first mode is deactivated, ensures the positioning of a vehicle to the nearest position that the vehicles are theoretically likely to occupy.
  • a slightly late vehicle is repositioned to its theoretical position.
  • an excessively late vehicle is repositioned to the next theoretical position, seen in the direction of scroll.
  • the control unit controls the vehicle driving means so as to advance the vehicle following the hole, in order to reduce the space formed. This movement is then reflected by a successive advancement of the following vehicles. Subsequently and infinitely, any vehicle crossing the timing section will be shifted as far forward as possible, without the installation can ever find a generally homogeneous distribution of vehicles. Therefore, the second mode of operation is generally activated when a vehicle is deposited.
  • control unit controls the drive means so as to reposition said vehicle to the following theoretical position, viewed in the direction of scroll where another vehicle is already present. Control systems then cause a complete shutdown of the installation.
  • the management of a hole is very delicate, if not impossible. Indeed, when the first operating mode of the control unit is activated, the timing means associated with the timing section are continuously actuated at each passage of a vehicle, which can lead to rapid wear of said timing means and a significant decrease in comfort for embedded users. On the other hand, when the second mode of operation of the command is activated, the complete installation is subject to untimely and unnecessary shutdowns.
  • the timing imposed by the timing section being chosen so that the vehicles have between them an equal time interval, the positioning modularity of the vehicles along the cable is zero. For example, it is impossible to configure the installation so as to have successive trains of vehicles, said trains being spaced long distances.
  • the aim of the invention is to overcome the above disadvantages by proposing a method for controlling the distance separating, at the output of a clocking section of a continuous-running cable transport installation, a vehicle and the vehicle preceding it, which allows to offer a great freedom of positioning of the vehicles along the cable.
  • this object is achieved by the fact that it consists in assigning to each vehicle an individual identification code, and in associating with said identification code a reference value representative of the desired distance for said vehicle.
  • the method according to the invention therefore allows to associate with each vehicle, a setpoint value representative of the desired distance, at the output of the timing section, between said vehicle and the preceding vehicle, seen in the direction of travel.
  • the set value is transmitted to the control unit before the journey of the timer section, which accordingly drives the drive means of vehicles in a conventional manner.
  • control method according to the invention makes it possible to distribute the vehicles by separating them according to different and predetermined spacings.
  • the setpoint associated with each vehicle via the assignment of the individual identification code can be changed at any time, for example by changing the assigned code or changing the setpoint associated with the code.
  • an aerial cable 10 of a chairlift-type transport facility extends in a closed loop between two loading / unloading stations, one of which is downstream, represented, passing through the stations on pulleys 12 main ones of which one drive drives the cable 10 continuously.
  • the cable 10 supports seats 13 coupled by detachable clips and staggered along the cable in a predetermined combination.

  • Such devices are well known and it is useless to describe them in more detail.
  • the slowdown sections A and acceleration B are connected by a contour section C along which the seats 13 circulate continuously at reduced speed by means of a drive device 19 consisting of tire trains 20 tire.
  • the drive device 19 of the contour section C is subdivided into three successive sections, each delimiting an elementary section S1, S2, S3, and which can have differential drive speeds.

  • one of the wheels 20 of the section delimiting the section S3 is rotated by one of the wheels of the acceleration section B.
  • a variable speed motor 23 (FIG. ) drives a transmission belt 24 stretched between two pulleys, one of which is mounted coaxially with one of the idle gears 21.
  • an unloading area 25 is arranged along the sections S1 and S2.
  • a boarding area 26 on the seats 13 is arranged coincidentally with the area swept by the seats 13 along the section S3, to allow skiers coming from an access gate 27 to sit on the seats 13.
  • the motor 23 which drives the five wheels 20 of the section delimiting the section S2 is controlled by a control unit 28, for example a PLC, which can perform other functions, in particular control and monitoring of the entire installation.
  • the control unit 28 receives a passage signal 29 representative of the passage of the seats 13, provided by a presence sensor 30 disposed along the section S1 and providing a pulse at each passage of a seat 13. It also receives a signal 31 from a read unit 32 provided upstream of the section S2, arranged at a predetermined location between the slowing section A and the section S2.

  • the control unit 28 also receives a clock signal 33, emitted by a detector (not shown) cooperating with the pulley 12 and emitting pulses synchronized with the movement of the cable 10.
  • the output of the control unit 28 delivers a control signal 34 to the motor 23 so as to provide a suitable control of the motor 23 for a predetermined timing of the seats 13 at the output of the section S2, the way that will be described later. Subsequently, the section S2 is called S2 timing section.

The wheels of the retarding section A brake the seat 13, while the following wheels 20 of the section S1 move it along the landing location 25 until reaching the reading unit 32, arranged on the along section S1.
  • the passage of the seat 13 generates a selection signal 31 representative of the individual identification code integrated in the radiofrequency tag 35 board.
  • the selection signal 31 is transmitted to the control unit 28, which integrates a correspondence table for associating with each identification code a reference value representative of the desired distance, at the output of the clocking section S2, between the seat 13 correspondent and the seat preceding it.
  • the control unit 28 determines the theoretical distance which will have to separate, at the output of the clocking section S2, the seat 13 about to enter the clocking section S2 and the previous seat 13, seen in the direction of travel.
