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 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 that are caught by the door when it is moved from being 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 operating system of the type mentioned is known from DE-A-3225536.
- 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 in such a way that, when pressure is applied to two control connections, it regulates a pressure. 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.
- This door actuation system offers the advantage that it enables monitoring of both directions of movement of the door without additional expenditure on components of the first emergency shutdown device.
- the check valve is required to achieve the above-mentioned safety function in this prior art.
- This device and thus also the door actuation system itself is complicated, prone to failure and expensive.
- the first emergency shutdown device has a combination of a minimum pressure switch (there 34 ') and a shut-off valve (there 31'), which, when the pressure falls below a minimum (as a measure of a predetermined door resistance), on the active surface of the actuating piston which determines the door movement (there 11 ') cancels the separation of the pressure medium supply lines (there 15', 16 ').
- the first emergency shutdown device only works with respect to one direction of door movement. To monitor the other direction of door movement, a second complete first emergency shutdown device with a minimum pressure switch and shut-off valve is required, and therefore considerable effort.
- a second emergency shutdown device (there 17 ', 21') with an emergency valve (there 21 ') is provided
- braking or damping of the door movement upon its re-actuation is only possible when the first emergency shutdown device is present and also only in the latter monitored door movement direction possible.
- Braking or damping the door movement in the other door movement direction when the emergency valve is actuated again requires additional measures, such as the throttle valve (there 20') or a second, complete, first emergency shutdown device.
- a braked or damped door movement if only the second emergency shutdown device (there 17 ', 21') with the emergency valve (there 21 ') is provided, in any case requires additional devices, such as the throttle valve (there 20').
- the invention has for its object to improve a door control system of the type mentioned while preserving its advantages 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 of force on the actuating piston, which can lead to injury or damage to objects detected in the door movement, which should also be understood to mean 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, if provided, with an emergency valve.
- a changeover valve provided in the prior art for the second emergency switching device and connected in series as an OR element to the check valve can be omitted.
- this shuttle valve enables the valve device to be acted upon by the check valve and via its first flow path second flow path, the action on the part of the emergency valve.
- the invention enables an emergency shutdown by both emergency shutdown devices by means of the same emergency valve 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 rapid movements of the door when restarting after actuation of the second emergency shutdown device are avoided, so that for this purpose in State-of-the-art switchable, complex throttle valve becomes 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 first emergency shutdown device monitors the opening resistance of the door, while its closing resistance is monitored by a monitoring device controlling a reversing device.
- 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 valve 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 switch 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 second actuating device, which is actuated essentially by the operating switching device, and an actuating device, which ensures the security functions mentioned above, are provided.
- the second 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 is simultaneously in opposite direction.
- the invention is designed with electrical or electronic control and electro-pneumatic adjustment of the valve device.
- the second 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 monitored visually 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 summary.
- 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 is also pressurized in addition to the active surface just acted upon. 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 can be designed in relation to one another in such a way that the resulting force is so low that the door comes to a standstill as a result of friction on the door seals and in the transmission mechanism, or can still slowly open or close in its end position .
- the invention causes the opening and closing surfaces of the door drive to be pressurized at the same time and, as described above, to come to a standstill or slow door movement in this case as well.
- the invention also enables designs with compressed air or with hydraulic fluids as pressure medium.

- the active surface 21 or 23 assigned to the respective 3/2-way valve 10 or 26 is vented. From the first 16 or 28 to the second switching position 11 or 27, each 3/2-way valve 10 or 26 can be changed over by the respective second actuating device 8 or 25. During this changeover, the 3/2-way valve 10 or 26, which is currently in its second switching position 11 or 27, is taken into its first switching position 16 or 28 via the coupling member 18.
- the 3/2-way valves 10 or 26 are independent of the respective second actuating device 8 or 25 and without coupling to the other 3/2-way valve 10 or 26 from their second switching position 11 or 27 in their first switching position 16 or 28 adjustable.
- the actuating devices 17 and 29 of the first and the second 3/2-way valve 10 and 26 are connected together with the outlet, hereinafter referred to as the working connection, of a third 3/2-way valve 5 designed as an emergency valve device.
- the third 3/2-way valve 5 is e.g. biased by a spring into a basic position 31 and also has a changeover position 4 and an actuating device 6 designed as an actuating magnet 6, upon activation of which it is placed in the changeover position 4.

- the present exemplary embodiment has an electrical or electronic evaluation and switching device 9 , hereinafter referred to as switching device 9, on.
- switching device 9 forms an operating switching device and also contains an automatic emergency shutdown device for a first emergency shutdown device and a reversing device.
- the automatic emergency shutdown together with a monitoring device 14 which monitors the opening resistance of the door, forms the first emergency shutdown device which, when the door detects an object in its opening movement, ie when the opening resistance reaches a predetermined value, violates or damages it by reducing the door opening force prevented.
- object means both people and things.
- the reversing device prevents damage or damage if the door detects objects in their closing movement.
- the reversing device evaluates signals from a monitoring device 13 monitoring the closing resistance of the door in such a way that when a predetermined closing resistance is reached, the door drive is reversed from the closing movement into the opening movement.
- the monitoring devices 13 and 14 are designed as differential pressure switches, which respond to a predetermined difference between the pressures acting on the closing surface 23 and the opening surface 21.
- the monitoring devices 13 and 14 can also be designed as sensors which sense other parameters for the respective door resistance, for example the opening speed or the closing speed of the door.
- the switching device 9 are also assigned limit switches 12 and 15, each of which is assigned to a door end position. These limit switches switch off the monitoring devices 13 and 14 when and as long as the door is in the respectively assigned end position. Without this limit switch, the switching device 9 in connection with the respective monitoring device 13 or 14 would react as if to an increased door resistance.
- the dash-dotted lines represent electrical connections between the above-mentioned devices, insofar as they are electrical or electronic.
- the emergency valve 3 In normal operation, as shown, the emergency valve 3 is in its normal switching position 34 and the third 3/2-way valve 5 in its basic position 31. As a result, the first and second 3/2-way valves 10 and 26 are pressurized at their supply connections and vented at their actuators 17 and 29.
- the switch 7 is actuated arbitrarily, whereupon, via the switching device 9 and the respective second actuating device 8 or 25, the first or second 3/2-way valve 10 or 26 which is currently in its first switching position 16 or 28 is switched to its second switching position 11 or 27.
- the switching device 9 determines the direction in which it had previously controlled the door and now controls it in the opposite direction of movement.
- the door is in a closing movement. If the door detects an object, the closing resistance increases. At a predetermined value of the closing resistance, the switching device 9, in conjunction with its reversing device, gives a pulse to the magnet of the second actuating device 25 of the second 3/2-way valve 26 which, as a result, moves from its first switching position 28 into its position second switching position 27 is set and thereby takes the first 3/2-way valve 10 from its second switching position 11 into its first switching position 16 via the coupling member 18.
- the closing surface 23 is vented and the opening surface 21 is pressurized, with the result that the door reverses (reverses) from its closing movement into its opening movement.
- the switching device 9 gives a pulse as an emergency signal to the actuating magnet 6 of the third 3/2-way valve 5 in connection with its automatic emergency switch-off device on the basis of the signals emitted by the monitoring device 14 and connects the actuating device 17 or 29 of the first and the second 3/2-way valve 10 or 26 with its pressurized first inlet 30 with the result that the actuating devices 17 and 29 are also pressurized, whereby the second 3/2 -Way valve 26 is placed from its second switching position into its first switching position 28.
- the closing surface 23 of the actuating piston 22 is also pressurized, as a result of which the opening movement of the door is braked or broken off or vice versa.
- the magnitude of the excess force in the opening or closing direction can be determined via the ratio of the opening area 21 to the closing area 23 such that the door either continues slowly in the opening or closing direction or comes to a standstill as a result of the friction in the transmission mechanism and on the door seals. It is obvious that the behavior of the door can also be influenced by the design of the friction elements. As a result, the pinching force acting on the detected object is in any case reduced to zero or to a harmless level.
- a second emergency shutdown device is started.
- the supply connections of the first and the second 3/2-way valve 10 and 26 are independent of the current operating state of the door operating system the ventilation of the emergency valve 3 is vented.
- the actuating devices 17 and 29 of the first and the second 3/2-way valve 10 or 26 are acted upon via the third 3/2-way valve 5, as a result of which the 3 / 2- Directional valves 10 and 26 is placed in its first switching position 16 and 28.
- the active surface 21 or 23 of the actuating piston 22 assigned to the relevant 3/2-way valve 10 or 26 is also vented via the venting of the emergency valve 3.
- both the opening surface 21 and the closing surface 23 of the actuating piston 22 are thus vented regardless of the previous operating state.
- the first and the second 3/2-way valve 10 or 26 are in their first switching position 16 or 28, so both the closing surface 23 and the opening surface 21 of the actuating piston 22 are pressurized.
- the control device 9 gives a pulse to the magnet of the second actuating device 8 of the first 3/2-way valve 10, which is thereby placed in its second switching position 11 and thereby connects the opening area 21 to the atmosphere.
- the door drive is set in motion in the closing direction.
- the pressure that is released from the opening surface 21 offers sufficient counterforce to allow this closing movement to take place with a brake.
- the first 3/2-way valve 10 is in its first switching position 16 and the second 3/2-way valve 26 is in its second switching position 27; only the opening area 21 is therefore pressurized.
- the switching device 9 in this case again gives a pulse to the magnet of the second actuating device 8 of the first 3/2-way valve 10. This is thereby placed in its second switching position 11 and takes the second one via the coupling member 18 3/2-way valve 26 in its first switching position 28 with.
- 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 slowed down by the pressure on the opening surface 21 starts again.
- 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.

- the second switching piston 57, 65 is shown in FIG. 2 in its second switching position, indicated by 11. In this second switching position, the second connecting chamber 58 is in such a position that it connects the second working connection 66 to the vent 54.
- the first actuating chamber 78 of the first switching piston 55, 80 is pressurized.
- the first switching piston 55, 80 is thereby placed to the right in its second switching position.
- the first shading piston 55, 80 takes the second switching piston 57, 65 with it via the operative connection between the end faces of the piston heads 55 and 57, respectively.
- the switching piston 55, 80 or 57, 65 which is currently in its second switching position, is placed in its first switching position over the end face of its piston head 55 or 57. Based on the illustration in FIG. 2, this means that the second switching piston 57, 65 is placed in its first switching position.
- both switching pistons 55, 80 and 57, 65 are in their first switching position, that is to say both working connections 79 and 66 are connected to the supply connection 52.
- the switching piston 55, 80 or 57, 65 which is currently in its second switching position, is placed in its first switching position even when the line connection 73 is pressurized.
- a valve device and an emergency valve device in the sense of the invention in particular the first 10 and the second 26 and the third 3/2-way valve 5 of the exemplary embodiment according to FIG. Including their actuating devices 8 and 25 and respectively 6 or 17 or 29 and the coupling member 18 united.
- its supply connection 52 is with the first working connection 33 of the emergency valve 3
- its second working connection 66 with the closing surface 23 and the line connection 73 to be connected to the second working connection 35 of the emergency valve 3.
- the first switching piston 55, 80 in connection with the actuating magnet 50 and the first actuating chamber 78 then correspond to the first 3/2-way valve 10 with its second actuating device 8, the second switching piston 57, 65 in conjunction with the actuating magnet 62 and the first actuating chamber 67 the second 3/2-way valve 26 with its second actuating device 25 and the operative connection between the end faces of the piston heads 55 and 57 the coupling member 18.
- the actuating magnet 70 corresponds to the third 3/2-way valve 5 with its actuating device 6.
- the actuating devices 17 and 29 of the 3/2-way valves 10 and 26 correspond to the second actuating chamber 56 in conjunction with the end faces of the piston heads 55 and 57 of the first and second switching pistons 55, 80 and 57, 65.
- the door valve described represents a very advantageous combination of the first and the second 3/2-way valve, in which the third 3/2-way valve of the door actuation system according to FIG. 1 is integrated with little effort.
- the door valve described is thus also a very advantageous summary of the valve device and emergency control device according to the invention.
