Definitions

  • the present invention relates to a door actuators, and particularly concerns a door opening and closing apparatus for an electric train.
  • FIGS 3a and 3b there is seen a schematic perspective view of a conventional door opening and closing apparatus for a train, and a schematic section of the pneumatic actuator.
  • a pair of doors 25 are arranged between an upper rail 26 and a lower rail 27, and are driven to be opened and closed by a door operating mechanism 28.
  • the door operating mechanism 28 uses compressed air as a power source and converts reciprocating motion of a piston in a differential air cylinder 281 to opening and closing motion of the door 25 through a rack and semicircular pinion gear 282 and a coupling link 283 to open or close the doors 25, 25.
  • FIG. 4 An example of a control portion for controlling the door closing mechanism 28 is shown in Figure 4.
  • the control portion comprises an electromagnetic valve 31, choke valves 32 and ball valves 33.
  • the control portion continuously supplies air to the smaller diameter cylinder 37, and selectively admits air into the chamber of a large diameter cylinder 36, which houses a large diameter piston.
  • the piston rod and pistons 34 and 35 move to the left as seen in Figure 4.
  • the piston rod and pistons 34 and 35 move to the right as seen in Figure 4.
  • the control portion controls the flow of air into and out of the two cylinder chambers, and also the space between the pistons, by means of two ball valves 33, 33, and choke valves 32, 32, and by means of the positional relation between two air exits and the cylinders, the driving speed of the door is decreased during the last stage of its opening or closing movement.
  • a door driving scheme as described above will be referred to as "pneumatic driving”.
  • an object of the present invention is to provide a door opening and closing apparatus which does not overstrain the door of an electric train, eliminates troublesome fine tuning of the door mechanism, eliminates operational delay of the door by avoiding the pneumatic drive, and drives the door finely and quickly.
  • a further object of the present invention is to provide a door opening and closing apparatus which facilitates opening and closing the door of an electric train in an emergency when normal electrical power supply is interrupted.
  • a door opening and closing apparatus for an electric train comprises a linear motor, and further comprises stator coils and a moving field means, and is mechanically coupled with a door of an electric train to drive the door along a linear path, an electric power converter for supplying electric power to the linear motor; a control circuit for controlling the electric power converter, by which to control the linear motor; and an emergency power supply means for supplying electric power to the electric power converter in an emergency, so as to enable opening and closing of the door in an emergency.
  • the door of the electric train By driving the door of the electric train with a linear motor, the door is not overstrained. Additionally, the door is opened and closed by the emergency power supply means and the control circuit in an emergency when the normal power supply to the power converter is interrupted.
  • a linear motor comprising stator coils 2 and a moving field means 3 is disposed in a frame 1.
  • the moving field means 3 may be formed by a plurality of field magnets or field coils.
  • an end cap 4 of the frame 1 is shown removed, and the linear motor is pulled out from the frame 1 so as to be illustrated clearly.
  • a door 6 is coupled with the moving field means 3 of the linear motor through a drive arm 8 and a coupling 5 so that the door 6 may be moved in parallel with a rail 9.
  • the door 6 is supported on the rail 9 by suspension members 7 and wheels 7a.
  • the moving field means 3 since the moving field means 3 is driven in parallel with the stator coils 2 by controlling current flow through the linear motor, the door 6 moves along the rail 9, by which opening and closing of the door 6 is facilitated. Since only horizontal force is exerted between the stator coils 2 and the moving field means 3 and since any unnecessary vertical or oblique force is not exerted, problems such as displacement of the fitting position of the door, wear of the structural constituent elements, etc. are not caused.
  • FIG. 2 is a block diagram showing a control portion (control circuit) of the linear motor.
  • a DC power supply 11 is fed to an inverter 13 and thence to a linear motor 14.
  • a capacitor 12 is coupled to the DC supply, with a diode to prevent reverse current flow.
  • An encoder 15 associated with the linear motor 14 provides information on the position of the door, while a current detector 16 monitors current being supplied to the linear motor 14.
  • a magnetic pole speed and position detector 17 receives signals from the encoder 15, and provides signals to a current regulator 18 and a speed regulator 19.
  • a position and speed pattern addresser 20, a parameter setting device 21 and an interface 22 receiving external signals 23 complete the apparatus.
  • the linear motor 14 is driven by the inverter 13.
  • the inverter 13 is connected with a major speed regulation loop comprising a speed regulator 19 and with a minor current regulation loop comprised of the current regulator 18 by which the switching elements of the inverter 13 are controlled, for example, by pulse width modulation.
  • position and speed of the magnetic pole or position of the moving field means are detected by a magnetic pole speed and position detector 17, based on the output of an encoder 15 associated with the linear motor 14.
  • the output of the magnetic pole speed and position detector 17 is fed to the current regulator 18, the speed regulator 19, and a position and speed pattern addresser 20.
  • the position and speed pattern addresser 20 generates a speed command from an operation command fed from the interface 22 as the external signal 23 based on the output of the magnetic pole speed and position detector 17, and feeds the speed command to the speed regulator 19.
  • the speed regulator 19 executes a predetermined regulation operation so as to bring the speed signal from the magnetic pole speed and position detector 17 into conformity with the speed command from the position and speed pattern addresser 20.
  • the current regulator 18 converts the output of the magnetic pole speed and position detector 17 to a current command, and executes a predetermined regulation operation so as to bring the current value detected by the current detector 16 in coincidence with the current command value.
  • Position-speed patterns can be set at will in the position and speed pattern addresser 20.
  • the capacitor 12 stores electrical power supplied from the DC power supply 11 while the door is closed, that is while the linear motor is not driven (while the electric train is running), and supplies this stored electric power to the inverter 13 when the normal power supply from the DC power supply 11 is interrupted by any cause. Therefore, by properly selecting the value of the capacity of the capacitor 12, the door may be opened and closed as many times as needed even in an emergency.
  • the present invention which is explained by way of example in relation to the opening and closing of the door of an electric train, is applicable to other sliding doors in the similar way as described above.
  • the door mechanism by driving the door of an electric train by a linear motor, the door mechanism is not overstrained, and cumbersome fitting and tuning of the door mechanism are eliminated. And by the provision of an emergency power supply, the door can be opened and closed predetermined times in an emergency when the normal power supply to the electric power converter which controls linear motor is interrupted.
