Definitions

  • the invention relates to a door actuation system, in particular for doors in vehicles for the transportation of people, with a pressure-actuated door drive and a door control device, according to the preamble of patent claim 1.
  • Door actuation systems in particular for doors in vehicles for the transportation of people, can have at least one first emergency shutdown device for safety reasons.
  • the first emergency shutdown device prevents people or things from moving the door can be caught, injured or damaged.
  • a second emergency shutdown device can also be provided.
  • the second emergency shutdown device enables the door actuation system to be stopped immediately by relieving the pressure on the door drive and interrupting the pressure medium supply, regardless of the first in any operating state via an emergency valve.
  • a door control system of the type mentioned is known from DE-OS 32 25 536.
  • a valve device controlling the pressurization of the active surfaces of the actuating piston is controlled such that both active surfaces of the actuating piston are relieved of pressure.
  • the valve device is preceded by a check valve designed as an AND gate.
  • the check valve is designed such that it controls a pressure when pressure is applied to two control connections. This modulated pressure is passed on to the valve device.
  • the shut-off valve is pressurized at both control connections.
  • the check valve then acts on the valve device in such a way that it is set such that both active surfaces of the actuating piston are relieved of pressure.
  • the invention is therefore based on the object of improving a door actuation system of the type mentioned at the beginning with simple means so that it provides the safety function mentioned without complicated, fault-prone and complex devices.
  • the invention is based on the idea of preventing an excess force on the actuating piston, which can lead to injury or damage to objects detected in the door movement, including persons, by the simultaneous pressurization of both active surfaces of the actuating piston.
  • the invention enables the simple design of a second emergency shutdown device, which may be provided, with an emergency valve.
  • a changeover valve provided in the prior art for the second emergency shutdown device and connected in series as an OR element to the shutoff valve can be dispensed with.
  • this shuttle valve enables the valve device to be acted upon by the check valve via its first flow path and to be acted upon by the emergency valve via its second flow path.
  • the invention enables an emergency shutdown by both emergency shutdown devices by means of the same emergency control device and thus also an arrangement of the second emergency shutdown device as the sole emergency shutdown device.
  • the invention also ensures that sudden or too fast movements of the door are avoided when restarting after actuation of the second emergency shutdown device, whereby a switchable, complex throttle valve provided for this purpose in the prior art is superfluous.
  • the above-mentioned first emergency shutdown device can monitor the door resistance in the opening direction (opening resistance) and / or in the closing direction (closing resistance).
  • the invention can be implemented with an emergency control device arranged parallel to the valve device or upstream of the valve device and / or an emergency control device controlling the valve device.
  • the emergency control device can be designed as an electrical / electronic control device for the valve device, which controls the latter when the first emergency shutdown device is actuated and / or when the emergency valve is actuated in the sense of simultaneous pressurization of both active surfaces of the actuating piston.
  • the emergency control device can be designed as a separate valve (emergency valve) that is controlled mechanically, by pressure medium, electrically / electronically or by a combination of these possibilities or that is combined with the valve device.
  • the first emergency shutdown device monitors the opening resistance of the door, while its closing resistance is monitored by a rever Sier coupled controlling monitoring device is monitored.
  • the valve device can advantageously consist of a first and a second 3/2-way valve, each of which is assigned to an active surface of the actuating piston, and the emergency control device can consist of a third 3/2-way valve.
  • the door actuation system according to the invention can also be combined with an operating switching device, the actuation surfaces of the door actuation piston being alternately pressurized and depressurized when actuated.
  • a combination of the door actuation system according to the invention with an operating switching device can advantageously be achieved in that the first and the second 3/2-way valve each have a first actuating device, which is actuated essentially by the operating switching device, and a second actuating device, which ensures of the above-mentioned security functions, if necessary.
  • the first actuating devices of the first and the second 3/2-way valve can be mechanically operatively connected such that when the one 3/2-way valve is switched from its first switching position to its second switching position, the other 3/2-way valve simultaneously in opposite direction.
  • the invention is with electrical or electronic control and electro-pneumatic adjustment of the valve device and electrical adjustment of the emergency control device.
  • the first actuating devices of the first and second 3/2-way valve and the actuating device of the third 3/2-way valve can be actuated by hand.
  • the closing resistance could be visually monitored by the operating personnel, which would make a control device unnecessary.
  • a mechanical control with / or without a control device with mechanical logic modules would also be feasible.
  • a pure pressure medium control would also be possible with a control device composed of pressure medium logic modules, in particular pneumatic ones.
  • Combinations of the control types mentioned and those of the control types mentioned with electrical or electronic components can also be carried out.
  • the control device of a preferred embodiment contains an automatic emergency shutdown and a reversing device. However, these can also be arranged separately, each individually or in combination.
  • the manually operated emergency valve in a preferred embodiment can be pressure medium or electrical, e.g. be actuated via an actuating magnet.
  • the door drive can be operated with an axially displaceable actuating piston, but also with other servomotors, e.g. with a rotary piston.
  • the invention has the effect that, when the first emergency shutdown device is actuated, the counter surface of the door drive also presses in addition to the active surface that has just been acted on is applied. As a result, a counterforce to the actuating force is built up on the counter surface, which causes the required security effect, namely the injury or damage to persons or objects detected during the door movement.
  • the opening area and the closing area in relation to one another can be designed such that the resulting force is so small that the door comes to a standstill as a result of friction on the door seals and in the transmission mechanism or can still open or close slowly into its end position.

  • the opening surface 21 is again connected to the atmosphere and the closing surface 23 is pressurized, with the result that a closing movement which is braked by the pressure on the opening surface 21 decelerates.
  • Recommissioning after an emergency shutdown by the second emergency shutdown device is done by switching the emergency valve 3 from its emergency switch position 2 to its normal switch position 34 and then actuating the switch 7. Since in this case the first and the second 3/2-way valve 10 or 26 are in their first switching positions 16 and 28, when the emergency valve 3 is switched to its normal switching position 34, both the opening surface 21 and the closing surface 23 are pressurized, with the result that, depending on the friction and surface area on the actuating piston, the door is braked in the opening or closing direction runs or stops. If the switch 7 is now actuated, the mode of operation described above for the case of restarting after an emergency shutdown by the first emergency shutdown device takes place. The above functional description makes it clear that the emergency valve can also be provided as the only emergency shutdown device.
