Definitions

  • the invention relates to a combined storage and drive system according to the preamble of claim 1 for an automatically operated door.
  • the combined bearing and drive system consists of a permanently excited magnetic support system, which has at least one fixed and at least one movable magnet row, with pairs of fixed and movable magnetic rows opposite one another being magnetically poled with the same name, and a linear motor that is coupled to the magnetic support system, the linear motor and the support system are housed in a common housing.
  • Such a bearing and drive system is known from DE 40 16 948 A1, wherein interacting magnets, under normal load, bring about contact-free, floating guidance of the door leaf which is movably held in a sliding guide by means of a linear motor.
  • the V-shaped arrangement of the permanent magnets is disadvantageous since such an arrangement cannot provide a laterally stable guideway for the rotor of the linear motor.
  • the bearing and drive system according to the invention has the advantage that, on the one hand, the guidance of the bearing can be functionally improved due to the optimization of the magnetic circuit arrangement of the support system and, on the other hand, the required load capacity can be achieved with a small magnet volume and consequently the magnet costs are low .
  • bearing and drive through the coupling of a permanent magnetic support system with a linear motor enables a compact and common arrangement in a suitable housing.
  • a linear, permanently excited levitation system is used as the support system, which is based on the repulsive force effect of identical magnetic pole structures.
  • the attached device e.g. B. doors of single or multi-leaf sliding door systems, can be moved easily and completely silently. Due to the contactless storage, there is no wear and there is no need for lubricants. Since there is no abrasion on the bearing and the bearing and drive system is completely arranged within a housing, malfunctions in the technological process are reduced to a minimum by external influences. By creating a constructive unit, no separate bearings are necessary. The result is a compact, mechanically robust and inexpensive drive.
  • the housing is advantageously made of a light material, such as. B. an aluminum profile.
  • a U-profile is preferable to other types of profile, particularly with high weight loads due to its inherent stability.
  • the arrangement of the linear motor depends on the type of housing used and the specific installation situation.
  • the linear motor can e.g. B. vertically below or above or laterally offset next to the levitation system, wherein the linear motor can be oriented horizontally or vertically in relation to the attached device. Any transverse forces that occur are compensated for by the bearing and drive system.
  • the device can be attached directly or indirectly to the rotor of the linear motor or to the floating part of the support system.
  • the indirect attachment takes place by means of a corresponding construction, for. B. in the form of a bracket or an arm.
  • the device must run in its own guide and the device-support system connection should compensate for any displacements that occur.
  • the doors are coupled in such a way that they are moved in opposite directions.
  • a connection of the two suspended support systems is advantageous.
  • the permanent magnetic bearing works on the principle of repulsive force. This operating principle enables a stable floating state without electrical control devices. No auxiliary energy is required to maintain the state of suspension.
  • Such magnetic linear guides are characterized by the fact that there is no mechanical friction due to their extreme ease of movement and silent operation, and they are wear and maintenance free.
  • the permanently magnetically excited support system is in an unstable balance due to the symmetrical structure.
  • the opposite rows of magnets are always magnetically poled with the same name in order to achieve the magnetic force effect.
  • Both the fixed support and the movable support are flat, so that the rows of magnets to be attached are each oriented in one plane and stable guidance results with the aid of the lateral guide elements. If the magnet system is exactly in the middle of the magnet rows, the lateral force is zero. This position is realized with the guide elements. With small tolerances, there are high lateral forces, which increase disproportionately with increasing displacement.
  • the suspension system is built into the support profile with a frame.
  • high energy magnets e.g. B. from neodymium-iron-boron (NdFeB)
  • NdFeB neodymium-iron-boron
  • the magnet system can be designed to be geometrically small and therefore space-saving with high-energy magnets for a given load-bearing capacity.
  • the high material costs of the high-energy magnets are at least compensated for by the comparatively small magnet volume.
  • the load capacity changes with the air gap, i. H. with the distance between the fixed and moving part of the support system.
  • the relationship between the deflection and the force is generally not linear.
  • the permanent magnetic levitation system can be constructed in one or more rows.
  • the magnetic circuit arrangements can be optimized by varying the direction of magnetization, the spacing of the magnet rows and the guiding of the magnetic flux through steel inserts.
  • the distance between adjacent rows of magnets has a decisive influence on the load capacities. With the same direction of magnetization of adjacent magnet rows in both the fixed and the moving part, this distance should be as large as possible.
  • the greatest load capacity is generated with a small magnet spacing.
  • a further increase in the load capacity is possible if the permanent magnets are surrounded by steel parts, so that the magnetic flux is concentrated in the area of the air gap.
  • Steel parts on the sides of the magnet rows and on the base surface of the magnets facing away from the air gap serve as magnetic inference.
  • the increase in load capacity is achieved by optimizing the thickness of the steel parts on the sides and on the base of the magnets.
  • the space-saving embedding of the magnets in the steel parts is particularly advantageous from a space-saving point of view.
  • the rotor of the linear motor is connected to the floating part of the support system, the magnet distance being located in the area of the power reserves of the high-energy magnets. Due to the high force effect of the high-energy magnets, the length of the carrier can be reduced to a minimum, so that only a few magnets are required.
  • a single or multi-phase AC linear motor in synchronous or asynchronous design is used as the drive. This can have a one-sided or double-sided effect.
  • the control or regulation of the linear motor is carried out with control electronics.
  • the travel path is recorded by sensors which mark the end positions of the doors and can also be used for locking functions.
  • the travel path can also be recorded using a magnetically incremental measuring system.
  • a double-acting linear two-phase synchronous motor which does not generate any transverse forces is preferred, so that the levitation system is not loaded transversely to the direction of movement.
  • the direct connection of the support system to the central runner creates an optimal arrangement in terms of weight distribution.
  • a bearing for guiding the runner is provided between the two parts, since small guide tolerances in the guide rail have to be compensated for.
  • a synchronous linear motor with an ironless rotor is used.
  • the electromagnetically active part has only the length due to the thrust force, while the part / parts which carry the permanent magnets have the length of the travel path plus the length of the electromagnetic part.
  • the movement is carried out by a short stator, which consists of a two-phase winding attached to a carrier. It is particularly advantageous that the masses to be moved are small, since only a two-phase winding is used. As a result, the power converter is also only two-phase and therefore inexpensive.
  • the use of such a motor enables an arrangement of the drive system which is advantageous in terms of assembly technology.
  • the drive is arranged horizontally next to the magnetic support system. So it will possible to assemble and disassemble the drive independently of the support system. This is not only important for commissioning, but especially in the case of repairs combined with an engine change, since only the engine has to be removed. Since the air gap of the support system can be made variable by designing the permanent magnetic arrangement, the contact-free operation of the support system can also be guaranteed even when the door is inclined. The freedom to make decisions about guiding the door on the underside can thus be made depending on the application.
  • the combined storage and drive system can also be used in feeders, handling devices or transport systems.

  • a device 8 arranged on the bearing and drive system 1 is attached either to the linear motor 2 or to the support system 7.

  • the housing 4 consisting of an aluminum profile is open at the bottom. U-shaped profiles in particular are suitable for such applications due to their inherent stability.
