Definitions

  • the invention relates to a sliding door with a magnetic drive system and an escape route functionality.
  • the magnetic drive system has a linear drive unit with at least one magnet row.
  • the term magnet series also includes elongated individual magnets.
  • the magnet series can be arranged stationary or mobile.
  • the magnetic drive system is preferably designed as a magnetic support and drive system.
  • a combined storage and drive system for an automatically operated door in which a permanently energized magnetic support system is symmetrical and has stationary and movable magnet rows, which are each arranged in a plane, wherein the support system in a labile equilibrium is located, and in which the support system has symmetrically arranged lateral guide elements, which can be stored in a roll shape. Due to the thus achieved laterally stable track results in a simple design and arrangement of the stator and rotor housed in a common housing linear motor, namely the ability to arbitrarily arrange stator and rotor of the linear motor with respect to the support system and with respect to the shape of stand and runners not to be limited by the support system.
  • an electromagnetic drive system for magnetic levitation and support systems is further known in which a stable suspension and support state is achieved by a suitable arrangement of permanent magnet and ferromagnetic material.
  • the permanent magnet puts the ferromagnetic material in the state of a magnetic partial saturation.
  • Electromagnets are arranged so that the permanent magnets alone by changing the saturation in the mounting rail are moved, and the coil cores are involved in the permanent magnetic partial saturation, which leads to the floating and wearing state.
  • WO 94/13055 shows a stator drive for an electric linear drive and a door provided with such a stand, which is suspended by means of magnets in the lintel of a frame.
  • a plurality of magnets or magnet groups are arranged on the door panel, the magnetic field strength is so large that an attraction force is achieved to a guide plate, which is arranged on the underside of the lintel, wherein the attraction is sufficient to lift the weight of the door.
  • the rope must be tightened each time the door is closed, whereby the drive motor is more heavily loaded and that the door is in the closed state under a bias, so that it by the engine, a clutch or a locking device in the closed Position must be kept.
  • an additional electromagnetic clutch in the drive train is usually necessary to reduce the friction occurring in the drive train by the elastic tension elements when opening. Due to friction, the elastic tension elements also generate noise during normal operation. Also, the elastic tension element provides an additional Component is that causes additional manufacturing costs and claimed additional space.
  • the elastic tension elements can age by the constant operation and load depending on the material used and thereby lose elasticity, whereby the opening force decreases or the tensile elements can break, so that a regular review and possibly a regular replacement are necessary.
  • a disadvantage of this solution is that an additional motor is necessary, which causes additional manufacturing costs and requires additional space, and that this solution offers only limited security, since the first motor could block when burned by caking the insulation materials.
  • a sliding door with a magnetic drive system for at least one door which has a linear drive unit with at least one magnetic series, so further that the advantages mentioned above remain low production costs and an escape route function is ensured.
  • the sliding door comprises a magnetic drive system for at least one door leaf, with a magnet row arranged in the drive direction, the magnetization of which changes sign in its longitudinal direction at certain distances, and a support slide connected to the magnet row, to which the door leaf can be fastened , as well as with a coil arrangement comprising a plurality of individual coils and coil cores which, with appropriate control of the individual coils, interacts with the magnet series, which induces feed forces, wherein the individual coils of the coil arrangement are assigned at least two phase strings and the individual coils assigned to a respective phase string are connected in parallel, an electric power storage and an emergency control, which is connected to the electric power storage and can open the sliding door in case of power failure or failure of the main control.
  • the sliding door comprises a magnetic drive system for at least one door leaf, with a magnet row arranged in the drive direction, the magnetization of which changes sign in its longitudinal direction at certain distances, and a support slide connected to the magnet row, to which the door leaf can be fastened , And with a consisting of a plurality of individual coils and coil cores coil arrangement, which causes an appropriate interaction with the magnet coil, the feed forces, wherein the individual coils of the coil assembly are associated with at least two phase strands and connected to a respective phase strand individual coils connected in series an electric power storage and an emergency control, which is connected to the electric power storage and can open the sliding door in case of power failure or failure of the main control.
  • the sliding door comprises a magnetic drive system for at least one door leaf, with a magnet row arranged in the drive direction, the magnetization of which changes sign in its longitudinal direction at certain distances, and a support slide connected to the magnet row, to which the door leaf can be fastened , And with a consisting of a plurality of individual coils and coil cores coil arrangement, which causes an appropriate action of the individual coils interaction with the magnetic series, the feed forces causes an electric power storage, an emergency control, which is connected to the electric power storage and the sliding door in case of power failure or failure the main control can open, and two or more auxiliary coils connected to the emergency control for opening the sliding door with a corresponding control.
  • the sliding door according to the invention with a magnetic drive system for the escape route function has no mechanical transmission means between the engine and the door, a failure of the escape route function by mechanical failure, for. B. by tearing or jamming of the belt, ruled out, so that according to the invention in comparison with the described method in conventional sliding door drives with mechanical transmission elements, a higher security is achieved.
  • the accumulator preferably used as an electric power storage can also be realized alternatively by a capacitor or a battery. When using a rechargeable electric power storage this is preferably charged automatically, so that there is always a sufficient emergency power available.
  • the fail-safe interconnection of the individual coils is achieved in the first alternative by a parallel circuit of the individual coils of a phase strand, since individual coils can fail here, z. B. by the wire melts or breaks a coil terminal, without the operation is negatively affected safety relevant.
  • the fail-safe interconnection of the individual coils is carried out by a series connection of the individual coils of a phase strand, since short circuits within a coil, z. B. by failure of the wire insulation of individual coils, can occur without the linear motor fails as a result, since individual failed coils do not interfere. Since a correspondingly thick wire can be used, a line or wire breakage is extremely unlikely and can be compensated with appropriate mechanical protection of the stator. Further, the series-connected coils of a phase string can be made of a single uninterrupted wire, so that breakage of a coil terminal in the series connection can be precluded. This shows that the required single-fault safety is given by the inventive short-circuit-proof interconnection of the coils of a phase strand.
  • the fail-safe design of the individual coils of the linear drive according to the invention is achieved by two or more additional coils for the emergency opening function, which can be operated with the emergency control independently of the main coil strand.
  • the coils can act like the main coils on the rotor.
  • the additional emergency opening coils may be mounted individually or in one or more groups between the main coils and in front of or behind them.
  • the additional coils provided for the emergency opening function can be made smaller than those provided for normal operation, since they are only operated at great time intervals for a short time, ie, for the respective single opening.

B. by a light signal, by an emergency opening or by a message to a central monitoring system, whereby a necessary maintenance or a necessary replacement of the electric power storage is displayed.
  • electronic monitoring of the electric power storage to be changed in fixed periods, which depend on the type of power memory. Thus, a battery must be changed more frequently than an accumulator, which in turn must be changed more frequently than a capacitor.
  • the sliding door according to the invention preferably further comprises an emergency control Weger writtenssystem whose output signal is fed to the emergency control, which executes a path-dependent commutation of the magnetic drive system based on the received output signal.
  • a separate position sensing system for the emergency control ie in addition to a position detection system for the main control ensuring normal operation, this can commutate the electromagnetic linear motor in a path-dependent manner as in normal operation.
  • This own path detection system can be designed simpler than that intended for normal operation, z. B. only by an incremental encoder, by means of which the absolute position of the door leaf can not be detected.
  • the emergency control route detection system can also serve merely as a backup for the route detection system used in normal operation, ie the emergency control normally uses the route detection system used in normal operation (by the main control) and only its own emergency control route detection system if it fails.
  • the emergency control of the sliding door according to the invention preferably carries out a time-controlled commutation of the magnetic drive system.
  • This alternative or additional time-controlled commutation of the electromagnetic linear motor in the emergency opening offers a particularly high level of operational reliability, since no route detection system is required for the emergency opening and therefore can not fail either.
  • the potential disadvantages of such timed commutation are of very little importance for emergencies.
  • a control of the movement ie, a targeted path-dependent acceleration and deceleration of the door, can be done in the event of a power failure by the existing incremental encoder of the main control. In the event of a total failure of the travel signal, the door can still open unregulated due to the time-controlled commutation.
  • both types of commutation can be implemented with a dedicated trip detection system, thereby providing a particularly fail-safe system, especially when the emergency control route detection system serves only as a backup to the route detection system used in normal operation.
