Definitions

  • Gates of the type in question here with a motor drive of a door leaf or the like which can be moved back and forth between two end positions along a specific path, in particular a door leaf which can be moved overhead, but also vertically displaceable roller doors, sliding gates or the like work with limit switches which operate the for the door leaf movement - for example by means of a radio signal - stop the drive motor that is in operation as soon as the door leaf reaches the actuated end position.
  • Such limit switches have been arranged in the vicinity of the end positions actually assumed by the door leaf, namely the actual switch on the frame or the guide rails of the door and an actuating part of the switch on the door leaf.
  • Such switch parts arranged near the bottom of the opening to be closed by the door in the edge region of the door opening are subject to the risk of damage, in particular in rough industrial operation.
  • Such a simulator which can preferably be arranged in the area of the drive or drive control, is protected against damage, dirt and moisture infestation, but it requires a particularly precise position coordination with the door leaf after installation of the door, for example in such a way that the beginning of the movement distance of the door leaf must exactly match the beginning of the displacement distance of the simulator. Given the high path transmission ratios given here, even slight deviations lead to the risk that the door leaf is driven beyond its end position and therefore collides with its guide or other objects. A so-called zero adjustment between the door leaf and moving simulator element therefore requires special care and sensitivity, which contradict the rough assembly process of the door installation.
  • the invention relates to the arrangement for the control of the motor drive of a door leaf or the like, which can be moved back and forth along a specific path between two end positions and, if appropriate, one or more intermediate holding positions, in particular a door leaf which can be moved overhead, with a taking of the Switching device indicating the respective end positions or stop position, the output signals of which are used to switch off the drive motor supply, with a reference point indicator device which generates a synchronization signal when the door leaf passes through an end position, with a storage device for recording, storing and indicating the end positions and the if necessary, at least one stop position and with a position-indicating device which specifies the actual value of the position of the door leaf assumed in the course of the door leaf movement and which makes a position value setting by means of the synchronization signal holds, which triggers the corresponding output signal for switching off the drive motor supply in response to the desired end position or the stop position of the door leaf determined by activation in accordance with the associated specification of the storage device when this respective position is reached.
  • a control arrangement is known from EP-A-0 083 947, which measures the actual torque requirement of the drive unit for moving the door leaf over its path and compares it with a correspondingly recorded curve in the event of operation. As soon as a certain spreading area around the recorded curve is left in operation, the drive motor is switched off or switched over because there is suspicion of an impact on the door leaf. Here too, the movement of the door leaf as such is monitored with the aid of a scanning device.
  • a drive device for a gate or a door with a DC motor and a position and speed detector device which works with detector pulses which are derived from the position of the magnetic poles of the drive, so that the mode of operation or position of the motor without further detector devices the control of the door leaf movement can be controlled while storing the sequence of opening and closing movements.
  • the invention has for its object to provide a door operator with a generic arrangement of a door drive dependent on the movement of the door leaf control of the drive motor, which is particularly reliable with a simple structure and, especially when commissioning the newly installed door, requires no difficult adjustment work.
  • the invention is based on the basic idea of synchronizing a position-indicating device indicating the respective movement position of the door leaf at least once on the way between the two end positions with the actual door movement, thereby making it possible for this indicating device to be faulty to a certain extent.
  • a reference point indicator device is actuated, which in turn conducts a synchronization signal to the position indicating device, whereby this indicating device points to a specific one Value is set, which may depend on the direction of travel of the door leaf through the reference point position.
  • a specific storage value is entered for each end position and for each holding position of the door leaf, which determines the value of the position-indicating device, upon reaching which the drive motor is stopped.
  • the position-indicating device is constructed as a simple increment counter, which therefore counts a simple pulse series which is emitted when the door leaf is moved and whose respective count value indication preferably occurs as parallel information at its corresponding multipole output, in particular as a dual-coded signal.
  • the storage device is also preferably constructed as a digital circuit device, which is correspondingly simply designed to correspond to the increment counter of the position-indicating device.
  • the reference point indicator device is also preferred in this way as a digitally working element designed, in the simplest way as a yes-no switch or as a threshold switch, in the case of more complicated signal processing, preferably also in the manner of dual-coded, parallel-occurring signal expressions.
  • the three circuit devices namely the reference point indicator device, the position indicating device and the storage device, can work together in different ways:
  • the position indicating device is set by the reference point indicator device to a certain value each time the door leaf passes through the reference point position, for example the specified value 0.
  • the position becomes - Indication device advanced in accordance with the movement of the door leaf, in particular switched on with regard to its count value, until it has the value of the storage device corresponding to the closest actuated stop position or end position. If the output information from the position indicating device on the one hand and the storage device on the other hand coincide, a feed control device is actuated for switching off the drive motor.
  • the reference point indicator device is particularly simple because only one and the same setting value is ever given to the position indicating device.
  • a comparator device is required in order to be able to determine the coincidence between the output signal of the position-indicating device and the storage value of the storage device corresponding to the position in question.
  • the signal of Entered storage device that corresponds to the next controlled stop position or end position following in the direction of flow.
  • the position-indicating device is then fed further until it reaches an "overflow value", for example 0 or the next decade or the like, the signal obtained from this overflow display value of the actuation of the feed control device for the drive motor serves.
  • the control can be set in the same way when it is started up for the first time.
  • the gate is installed at the place of use, the reference point position is defined somewhere between the two end positions and preferably outside the one or more stop positions that may be provided.
  • the reference point position is preferably provided between the closed position and the next adjacent stop position, since it is to be expected that the door leaf will generally be moved back and forth between these two positions when the stop position is actuated, and it is rather the exception if this is the case Torbiatt is lowered from the open end position into the holding position.
  • the choice of the reference point position is generally made in such a way that the door leaf passes through the reference point position in every movement phase.
  • two or more reference point positions with a corresponding number of reference point indicator devices can also be provided, in the latter case in the neighboring area the stop or end position that is to be approached with particular accuracy.
  • the door leaf Before the normal operation control is put into operation by third parties, the door leaf is in any position, in a similar way the position indicating device and the storage device and, in the case of a bistable version, the reference point indicator device are in a state of undefined value specification. It is therefore necessary to adapt the actual state of the door leaf to be put into operation on the one hand and that of the control devices on the other.
  • the reference point position is first determined, which is located in the manner described between the end positions and outside of any intended stop positions. As will be explained further below, this can be done by arranging the reference point indicator device on the door frame or the door guide or the like in a correspondingly locally determined manner, or else it can be defined in the context of a door leaf movement simulator device.
  • the door leaf is moved manually with the help of a push button (dead man's operation) in the direction of the reference point position and over it.
  • a synchronization signal is sent from it to the position indicating device, which sets it to a specific value, in particular the specified value zero.
  • the position-indicating device is switched on and stopped in the initially desired position.
  • the specified value then appearing at the output of the position-indicating device is transferred with the aid of an input key into a memory unit of the memory device assigned to this stop position or end position and is permanently recorded there.
  • the door leaf is moved further into the next stop or end position and stopped in the position, whereupon with the aid of a further input switch the indication value of the position indication device corresponding to this position in turn into a memory unit assigned to this position the storage device is taken over.
  • the door leaf is now guided in the opposite direction over the reference point position, so that the position indicating device is again set to the specific value, preferably a zero value specification.
  • the closest stop position or end position is actuated and the resulting value of the position indicating device is in turn written into a storage unit of the storage device provided for this position using an input key.
  • the position indication device is forcibly set by the or each synchronization signal to the specific value, in particular specification value zero, and changes its value depending on the distance in the direction of travel until the next stop or end position of the door leaf.
  • the position-indicating device can be controlled in a correspondingly backwards manner with respect to its value, so that, in the case of a stop position which lies in this direction before the reference point position, coincidence between the initial value of the Position indicating device and that of the associated storage unit occurs.
  • the drive motor can in turn be switched off by corresponding actuation of the feed control device.
  • the modulation of the position indicating device can be handled as a function of the door leaf movement path beyond the reference point position, that is to say if the position indicating device is forced to the specific value, preferably the zero value specification, when passing through the reference point position.
  • a value in a negative range can also be considered.
  • a pulse generator is therefore preferably provided, which permits signal detection dependent on the travel or direction of rotation.
  • an encoder disk which is driven by the drive motor, in particular its output shaft, is preferably provided, which has two scanning tracks and at least two signal transmitter configurations which enclose angles of different sizes between them.
  • Another possibility is to change the modulation of the position-indicating device when passing through the reference point position after the end or stop position values have been stored in such a way that the value of the storage unit of the storage device is now entered into the position-indicating device when passing through the reference point position. which corresponds to the controlled stop or end position.
  • the counter can then run back from this value to the determined value, preferably the zero value specification, in the course of the movement of the door leaf into the desired position and generates an actuation signal for the feed control device when it reaches this specific value or zero value reached.
  • control devices can be designed in their entirety for this purpose so that they do not lose their signal content in the event of a power failure.
  • this is relatively complex, particularly with regard to the position indication device.
  • the memory device in a particularly preferred version it is therefore proposed to design the memory device as a "non-volatile" circuit device, in such a way that the memory content is not lost or changed in the event of a power failure.
  • the position indication device on the other hand, should be constructed as a "volatile" circuit unit, ie it loses its respective position indication value in the event of a power failure.
  • the reference point indicator device is provided with a bistable switching element which, even in the event of a power failure, indicates in which of the two directions of movement the door leaf is located from the reference point position.
  • bistable switch is used to ensure when the drive is switched on again that the door leaf can only be moved in the direction of the reference point position and now, as described above, when the reference point is passed, the position-indicating device is adjusted accordingly. In this way, the synchronization between the door leaf position and the specified value of the position-indicating device is restored after a power failure.
  • a bistable indicator switch is preferably used, which changes its switching position accordingly when the door leaf passes through the reference point position if the power supply has failed .
  • a switch can be provided which is switched by physical-mechanical attack; a magnetically operated bistable switch is preferably provided, as will be explained in more detail in connection with the exemplary embodiment shown in the drawing.
  • the synchronization of the door leaf position with the value specification of the position-indicating device and the storage of the end or, if necessary, stop positions is carried out in such a way that the completely installed door leaf by means of a manually operated pushbutton switch (dead man's operation) first in one direction and then in the Moving in the opposite direction beyond the reference point position.
  • the position-indicating device is set to the specific value, in particular a zero-value specification, so that the setting described above is ensured during initial commissioning.
  • the reference point indicator device can be arranged actuated directly by the door leaf, that is to say, for example, have a switch device arranged in a stationary manner on the door frame, the door leaf guide or the like, which is actuated by a switching element carried by the door leaf. It will usually be possible without any problems to mount the switch device and the switching element on the frame or guide or the door leaf at the factory before installing the door, so that such installation work is not necessary in the course of door installation. A tolerance field can also be provided, particularly in the case of a magnetically actuated switching device, which eliminates the need for adjustment work after the door has been installed.
  • the switch device is again stationary and the actuating switching element is arranged on a component that reproduces the door leaf movement in a step-down manner, for example on a spindle nut, the spindle of which is connected to the output of a reduction gear connected downstream of the drive motor.
  • a spindle nut the spindle of which is connected to the output of a reduction gear connected downstream of the drive motor.
  • the door leaf is moved into the closed position by means of a pushbutton switch (dead man's switch) and the spindle nut is connected to the spindle in such a way that after moving the door leaf out of the closed position with the help of the motorized drive, the spindle nut with the switching element passes the stationary switch device , whereby the reference point position of the door leaf is fixed within the scope of the simulator.
  • a pushbutton switch dead man's switch
  • a shift of the switching point occurs in the respective direction of movement relative to the idealized exact reference point position of the door leaf, ie a "hysteresis", which is caused by the spatial delay of the switch in relation to the direction of movement is and which, for example, leads to the fact that the position-indicating device moves to the open end position by switching the Indicator device at a lower increase in value - for example fewer counts - receives than when moving back from the open end position until the indicator device is switched differently.
  • this hysteresis is irrelevant in the event that the respective position is always assumed from one direction of movement and the reference point position is passed. This is the case with the end positions of the door leaf.
  • the stop positions can in principle be approached from both directions of movement, so that here the hysteresis or path-dependent switching delay of the indicator switch lead to different positions of the door leaf in the stop position.
  • this will generally be irrelevant in these stopping positions because here there is no mechanical resistance to the door leaf movement, as is the case when the end positions are reached. This means that the stop positions can be provided with so much "play" at the desired value that the inaccuracies caused by the hysteresis are irrelevant.
  • the delay of the switch can be determined with the aid of a further memory device and its value can be used for correction in such a way that one from both directions of movement approached stop position can be assumed exactly in the same place.
  • the stop position can certainly be provided in the spatial hysteresis area of such a reference point indicator device which is subject to hysteresis. When moving in one and / or the other direction from such a stopping position that is then actually taken up in a controlled manner, actuation of the reference point indicator device will then have to be provided.
  • FIG. 1 shows a schematic block of a switching device 1, which comprises a counter 2 as part of a position-indicating device and a comparator 3.
  • a total of a pulse generator 4, a switch of a reference point indicator 5, a memory device 6, an input switch device 11, a feed current control device 12 and a counter position indicator 13 are connected to this switching device 1.
  • the switching device 1 is provided with further links and switching elements that are required according to the respective function or cooperation of the individual aforementioned switching groups.
  • the pulse generator of the exemplary embodiment comprises a sensor disk 7, which is connected to the output shaft of the drive motor in a manner that is not shown in a rotationally fixed manner.
  • One of the two scanning devices 8 arranged diametrically with respect to the axis of rotation of the encoder disk 7 is on a circumferential track lying radially further out is set, in the course of which an elongated hole 9 extending in the circumferential direction is provided in the encoder disk 7, while the other scanning device 8 is directed to a radially inner circumferential track of the encoder disk 7, in the course of which an elongated hole 10 extending in the circumferential direction is provided .
  • the two elongated holes 9 and 10 are not diametrically opposed to one another, so they form a smaller angle between them in one circumferential direction than in the other circumferential direction.
  • the time interval between a pulse generated by the elongated hole 9 and that caused by the elongated hole 10 is shorter in one direction of rotation than in the other. In this way it is possible to determine the direction of rotation of the drive motor and thus the direction of movement of the door leaf with the aid of this pulse generator 4.
  • the reference point indicator device 5 which is only indicated with regard to the switch in FIG. 1, is explained in more detail in FIG. 2 on the basis of a preferred exemplary embodiment.
  • a switch device arranged on the frame 14 comprises a permanent magnet body 16 which is pivotably mounted about an axis 17 approximately in a plane running parallel to the door leaf being guided past.
  • the permanent magnet body 16 is polarized in the direction diametrically to the axis of rotation 17 such that one magnetic pole in the pivoting area of the permanent magnet body 16 points in the direction of the door leaf 15, while the opposite pole is directed away from the door leaf 15 in the limited pivoting area.
  • a switching magnet 18, also designed as a permanent magnet is arranged on the door leaf 15 in such a way that its one pole points in the direction facing away from the frame 14, while the opposite pole is directed toward the frame 14.
  • the switching magnet 18 fixedly arranged on the door leaf 15 is guided past the permanent magnet body 16 when the door leaf passes through the reference point position, which is predetermined by the spatial arrangement of the switch device with the permanent magnet body 16 on the one hand and the switching magnet 18 on the other hand, and exercises with its opposite pole a magnetic attraction force from the pole of the permanent magnet body 16. If one starts from the position of the magnets shown in FIG. 2 and moves the door leaf in the direction of the arrow shown following the switching magnet 18, the switching magnet 18 exercises the permanent magnet body 16 as it approaches a tightening force, so that it pivots about its axis of rotation 17 when the switching magnet 18 is moved past.
  • the switch device of the reference point indicator device 5 is designed to be bistable in the following way:

  • the position stabilizer magnet 20 is arranged such that it is aligned with its opposite pole on the opposite pole of the permanent magnet body 16 of the same name. This results in a magnetic repulsion movement between the fixed position stabilizer magnet 20 and the rotatably mounted magnetic body 16, so that the position stabilizer magnet 20 always presses it into one of its two end pivot positions.
  • the lab stabilizer magnet 20 is weaker on the permanent magnet body 16 with regard to its size and / or arrangement acting as the switching magnet 18, so that the latter can pivot it in the course of its past the permanent magnet body 16 against the repulsive force of the position stabilizer magnet 20.

  • no actuation of the switch 19 would take place during this first runover, and thus also no synchronization pulse to the zero position of the counter 2 are generated.
  • the door leaf will always be moved to and beyond the reference point position by means of a push button and then stopped and run through the reference point position in the opposite direction, because in any case the reference point indicator device is actuated at the latest when the reference point position is passed a second time
  • the permanent magnet body 16 is pivoted and the switch 19 is thus transferred from one switching state to the other. In this way, the zero position of the counter is ensured, so that now in the course of the further movement of the door leaf, a corresponding count of the pulses generated by the pulse generator 4 by rotating the encoder disk 7 and correspondingly controlling the scanning devices 8 is carried out.
  • a switch of the input switch device 11 assigned to this position is then actuated, as a result of which the counter output value is transferred to a memory unit of the memory device 6.
  • the counter is reset to zero again by actuating the switch 19 of the reference point indicator device 5, and the counter is switched on as described above when the door leaf is moved further, as described above, until the in stop position or end position closest to this direction of movement is reached, whereupon the associated switch of the input switch device 11 is actuated and the counter output value is transferred to a memory unit of the memory device 6 assigned to this position.
  • the output signals of the counter are present as a dual-coded signal on several parallel lines and are input to the memory device in parallel by the input switch device 11 in this waveform.
  • the initial commissioning of the gate is therefore particularly simple in that the gate only has to be moved into the individual positions via touch mode (dead center switch), whereupon a switch of the input switch device assigned to this position is actuated. It is only necessary to ensure that the reference position is first passed over in one direction and then in the other. As soon as all positions have been started and the corresponding counter values have been stored, the gate is ready for operation.
  • the drive is switched on with the help of an appropriate keyboard or a radio signal and it is determined in which positions the door leaf should be moved. This switches the drive motor on and the counter begins to record the position of the moving door leaf.
  • the corresponding storage unit is determined by specifying the target position, and a comparator device continuously checks the output signal of this storage unit and that of the counter. If these two outputs coincide, the comparator outputs an output signal to the feed control device 12, whereupon the latter interrupts the motor feed circuit and, if necessary, triggers further displays and the like.
  • the display device 13 can display the counter reading, facilitate its function monitoring, indicate the position of the gate above or below the reference point position and the like.
  • the present drive and control device operates in a current-dependent manner, care must be taken to ensure that in the event of a power failure and restart, the door cannot be operated incorrectly.
  • the power failure can occur very briefly or overnight, briefly, without being noticed, so that it must be ensured that when the operator is next switched on, the door leaf position corresponds to the value setting of the position-indicating device brought. If a power failure occurs in such a way that a hand-operated door leaf movement takes place in the meantime, then it must again be ensured that when the power supply is switched on again, the door leaf position corresponds to the value position of the position-indicating device.
  • the reference point indicator device is initially designed to be bistable. It basically indicates whether the door leaf is above or below the reference point position with regard to its switching element - switching magnet 18.
  • the reference point indicator device is implemented in the present example with the aid of permanent magnets, so that the permanent magnet body 16 is actuated by the switching magnet 18 that is passed even when the current is interrupted.
  • the reference point indicator device therefore reliably and in each case indicates where the door leaf is located. This information is used to ensure that the door leaf can now be moved only in the direction of the reference point position and beyond it with the aid of the electric drive which is now ready for operation again.
  • the counter of the position indicating device is reliable again is synchronized with the position of the door leaf.
  • the counter could in principle be designed as a non-volatile switching unit, that is to say retain its count value even if the power fails.
  • this advantage would only be used reliably if the counter were to continue to operate according to the newly adopted door leaf position even in the event of a power failure and manual door leaf movement. In the case of an electrically operated meter, however, this would only be possible with an auxiliary power source. Therefore, in a particularly preferred embodiment, the counter is constructed from simple switching elements that lose their information in the event of a power failure.
  • the counter receives its position by actuating the reference point indicator device, as when switching on for the first time. It is therefore only necessary to create the storage device from non-volatile switching elements in order to enable reliable resumption of operation even after a power failure.
  • the switch 19 in FIG. 2, which is otherwise only represented symbolically, can be, for example, a reed contact, as is commercially available magnetically actuated.
  • the position stabilizer magnet 20 can of course be replaced by other magnet arrangements, for example two small magnets, each of which is assigned to one of the two stops and exerts a magnetic attraction force on the permanent magnet body 16 so that it is drawn into the respective end pivoting position.

  7. Dispositif selon la revendication 5, caractérisé en ce que le disque émetteur présente, répartis à la périphérie, un ou plusieurs domaines magnétiques qui commandent par impulsion un élément détecteur à sensibilité magnétique - par exemple un générateur de Hall - en fonction du mouvement de rotation du disque émetteur.
  8. Dispositif selon l'une des revendications 5 à 7, caractérisé en ce que l'écartement en périphérie entre au moins deux marquages (9, 10) du disque émetteur (7) déclenchant des signaux répartis à la périphérie est plus faible, vu dans un sens de rotation, que dans l'autre.
  9. Dispositif selon l'une des revendications 1 à 8, caractérisé en ce que l'émetteur de signaux (4) présente deux pistes de signaux pour une détection de signal différente selon le sens de rotation.
  10. Dispositif selon l'une des revendications 6, 8 et 9, caractérisé en ce que le disque émetteur (7) présente deux trous oblongs s'étendant sur des pistes périphériques radialement différentes (9, 10), à chacun desquels correspond un contacteur de barrage photo-électrique (8) et dont l'intervalle de commutation vu en sens périphérique inclut des angles différents.
  11. Dispositif selon l'une des revendications 1 à 10, caractérisé en ce qu'aux sorties du dispositif de donnée de position (2, 4) et du dispositif de mémoire (6) est raccordé un dispositif (3) comparateur, qui par coïncidence des signaux de ces sorties enclenche un dispositif de commande d'alimentation (12) de l'entraînement.
  12. Dispositif selon l'une des revendications 1 à 11, caractérisé en ce que le signal de synchronisation du dispositif indicateur de point de référence (5) règle le dispositif de donnée de position (2) chaque fois à une valeur de point de référence fixée - par exemple zéro.
  13. Dispositif selon l'une des revendications 1 à 10, caractérisé en ce que le signal de synchronisation du dispositif indicateur de point de référence (5) règle le dispositif de donnée de position (2) à une valeur qui est fixée par la valeur de donnée du dispositif de mémoire (6), qui correspond à la position terminale ou à une position d'arrêt définie par programmation, vers laquelle le panneau de porte se déplace en dépassant la position de point de référence, de sorte que le dispositif (2) de donnée de position en atteignant cette position terminale ou d'arrêt émet une valeur qui commande un dispositif (12) de commande d'alimentation (12) de l'entraînement.
  14. Dispositif selon l'une des revendications 1 à 13, caractérisé en ce que pour la position finale du dispositif de mémoire (6) lors de la première mise en service et pour la manoeuvre à la main et sous surveillance du panneau de porte dans les deux positions terminales, et le cas échéant dans une ou plusieurs positions d'arrêt, on prévoit un dispositif (11) d'entrée-coupure, qui permet au passage de chaque position par manoeuvre manuelle du contacteur, l'enregistrement en case mémoire caractérisant la position prise en fonction de l'indication de valeur respective du dispositif (2) de donnée de position.
  15. Dispositif selon la revendication 14, caractérisé en ce que le dispositif d'entrée-coupure (11), le dispositif de mémoire (6), le dispositif de compteur (2), le dispositif de donnée de position (2, 4) et le cas échéant le dispositif comparateur (3) s'il est prévu, sont équipés de transmission parallèle de signaux binaires.
