Description
The present invention relates to a kind of combination support and drive system of operation door automatically of being used for by claim 1 preamble.Combination support becomes with a straight line group of motors with the magnetic supporting system of drive system by a permanent magnet excitation, the former has at least one column position fixing magnet and the variable magnet of at least one column position, wherein paired aspectant fixed-site is identical with position changeable magnet strip polarity, linear electric motors are connected with magnetic support system, and wherein linear electric motors and supporting system are installed in the common housing.
By the supporting and the drive system of known a kind of this type of DE 40 16 948 A1, wherein mutual coefficient magnet acts as the noncontact suspension guide rail that remains on the door leaf in the slide rail by means of a straight line motor movingly when normal load.Here shortcoming is the v-shaped structure of permanent magnet, because can not realize firm side guide for linear motor armature by this structure.
Known in addition, linear moving apparatus is typically by means of the mechanical support guiding, and is connected with rope, belt, cog belt or the like drive unit with the electric rotating machine form.Motor can be controllably or is regulated ground automatically and move.Supporting has determined high infrastructure cost with separating of driving, secondly because the machinery contact at supporting position causes wear phenomenon.
Therefore the objective of the invention is to develop a kind of supporting and drive system, make to improve and use under the situation that material and cost reduce to form a kind of system that saves the space in function by claim 1 preamble.
The feature that this purpose is used in regulation in the claim 1 realizes.The preferred structure of the content of claim 1 provides in the dependent claims.
The present invention has such advantage by the supporting and the drive system of claim 1, because the optimization of supporting system magnet loop configuration can improve the guiding of supporting on the one hand in function aspects, meet the requirements of supporting force with little magnet volume on the other hand, so the magnet expense is lower.
Can be installed in the suitable housing by an integrated compactness and the common structure of making of the function in conjunction with supporting that forms and driving of permanent magnetism supporting system and linear electric motors.The suspension system that adopts the linear pattern permanent magnet excitation is as supporting system, and it is based upon on the basis of repulsive force effect of like pole structure.So the device that hangs, for example single door of fanning or fanning more sliding door device can be flexibly and is not had sound ground to move fully.Because wearing and tearing do not appear in non-contacting supporting, and can be not with lubricator.Because do not produce wearing and tearing on bearing surface, and supporting and drive system be installed in the housing fully, and the functional fault of the activities that is caused by ectocine is reduced to minimum limit.Owing to caused an element of construction not need independent supporting.Obtain a compactness, that mechanical aspects is firm and cheap drive unit.
Housing is suitable for by lightweight material, and for example aluminium extruded sections constitutes.Here particularly when big weight loading because its good stability intrinsic with respect to the section bar of other type, the therefore preferred U-shaped section bar that adopts.
The layout of linear electric motors depends on the shell type that adopted and concrete mounting condition.Linear electric motors can for example vertically be installed in the following of suspension system or above, or side direction is installed in its next door with staggering, wherein linear electric motors can be towards horizontal direction or vertical direction orientation with respect to the device that hangs.The lateral force that occurs is compensated by supporting and drive system.Device can be fixed on the armature of linear electric motors directly or indirectly, or on the suspension of the supporting system part.Here indirect securement can be by means of corresponding structure, and for example square or arm shape structure is carried out.Device must move in guide rail itself in principle, and the connection of installing a supporting system should compensate moving of being occurred.Wherein the connection of door is carried out in this wise when being used in multi-door door leaf door gear, and they are moved in opposite directions.Here the connection of two suspension supporting systems is favourable.
The permanent magnetism supporting is by the repulsive interaction principle work of power.This action principle can reach stable suspended state, and does not need electrical adjustment devices.Do not need auxiliary energy in order to obtain suspended state.This magnetic supporting line slideway is characterized in that owing to having eliminated friction, good especially flexibility and muting working method, and do not wear and tear and service free.
The supporting system of permanent magnet excitation is owing to the symmetry of its structure is under the unsettled weight balancing state.One magnet strip is arranged respectively on fixed bearing and movable support, and they leave or do not leave certain distance mutually according to the difference of structure.Aspectant magnet strip all is that polarity is identical aspect magnetic under the sort of situation, so that reach magneticaction.No matter it is flat to be that fixed bearing or movable support are all made, therefore the magnet strip that is fixed on above it runs on one plane separately, and obtains stable guiding by means of a side direction director element.If magnetic force systems just in time is positioned at the center of magnet strip, lateral force equals zero so.Realize with director element this position.When error is very little, obtain very big lateral force, along with the increasing lateral force hypergeometric example that moves increases.The guide rail suspension system enough big for rigidity is installed in the bearing section bar with a framework.
By using high energy magnet, for example forming, because its higher residual magnetic induction can produce than using the much higher force density of hard magnetic ferrimagnet by neodymium iron boron (NdFeB).Therefore when the supporting force of regulation, on physical dimension, can do forr a short time, thereby save the position with the high energy magnet system.The Master Cost that high energy magnet is high is compensated by smaller magnet volume at least.
According to the principle supporting force with air gap, just the standing part of supporting system and the difference of the spacing between the motion parts change.Air gap supporting force more little, that produce in magnet system is big more.Relation between side-play amount and the power is normally nonlinear.
The permanent magnet suspension system can be made single-row or multiple row.Magnetic structure can be by the change of the direction of magnetization, the spacing optimization of magnet strip, and the guiding of magnetic flux can be improved by the steel shim.
Spacing according to the different adjacent magnets bars of magnet arrangement plays decisive influence to supporting force.No matter this spacing should be big as far as possible when identical for the adjacent magnets bar direction of magnetization in that fix or the part of motion.When fixing magnet strip with part motion is a same polarity, but adjacent magnet strip produces maximum supporting force when the magnet spacing of minimum when being this structure of opposed polarity.
If permanent magnet is surrounded by steel part, make flux concentration in the air gap zone, supporting force can further increase so.Here in the magnet strip side with magnet dorsad the steel part on the bottom surface of air gap as magnetic conductance yoke (Rueckschluss).The raising of supporting force reaches by the thickness optimization of the steel part on magnet side and bottom surface.Imbed advantageous particularly in the steel part from the viewpoint magnet surface of saving the space with flushing.
The armature of linear electric motors partly is connected with the suspension of supporting system, and wherein the magnetic spacing concentrates in the storage power district of high energy magnet.Because it is minimum that the length of the big bearing of high energy magnet active force can be reduced to, therefore only need a spot of magnet.
Adopt synchronously or the single-phase or polyphase ac linear electric motors of asynchronous structure as drive unit.It can single-ended or both-end work.The control of linear electric motors or adjusting are carried out with an electronic-controlled installation.Detect mobile distance by means of sensor, sensor sheet illustrates the final position of door and can be used for chain function simultaneously.Mobile distance also can be measured with magnetic increment type measuring system.
Here preferably adopt both-end effect two-phase linear synchronous motor, it does not produce lateral force, and the guide rail that therefore suspends is perpendicular to the direction of direction of motion bearing load not.Supporting system and the armature that moves at the center directly be connected the layout of having created a kind of the best aspect the distribution of weight.The supporting that is used for the armature guiding is arranged between two parts, because needn't compensate the steering error in the guide rail.
In a kind of superior structural of the present invention, adopt the linear synchronous motor that has coreless armature.The part of electromagnetic excitation only has the length by the thrust decision, and the part/part of supporting permanent magnet has the length that mobile distance adds the electromagnetism part.Motion is carried out by short stator, and it is made up of two phase windings that are installed on the bearing.The little advantageous particularly of moving-mass is because only adopt two phase windings.Therefore the rectifier of power supply also has only two-phase, thereby does cheaply.
Adopt such motor to make drive system can have the good structure in assembly technology aspect.Drive unit flatly is installed in the next door of magnetic supporting system.Thereby drive unit can be mounted and dismounted independently with respect to supporting system.This is not only when operation meaningful, and has decisive meaning when being related to the repairing of changing motor, because only need tear motor open.Because the air gap of supporting system do can be by permanent magnet structure the design parameters change, even door can guarantee that also supporting system moves non-contactly when tilting.Therefore the conclusive gap of the guide rail of door on the bottom surface can adapt with the application scenario.
Except being used for also can being used for input unit, operating means and transportation system with this knockdown supporting and drive system the driving of the door of supporting and inlet.

The sketch of supporting and drive system 1 has drawn in Fig. 1 to 4.Wherein linear electric motors 2 link to each other with supporting system 7, and are installed in together in the housing 4.The armature 5 of the position changeable of linear electric motors 2 partly links to each other by means of the suspension of linkage 6 with supporting system 7.Difference according to form of structure is not to fix a device 8 that is installed on supporting and the drive system 1 on the linear electric motors 2 exactly on the supporting system 7.This device 8 can for example be set up and the door of unillustrated automatic door facility or being connected of inlet.Except being used for also can being used for input unit, operating means or transportation system with this combination support and drive system 1 driving of the door of supporting or inlet.
Supporting system 7 is made up of a bearing 9 that is fixedly mounted on the housing 4, and the sheet material shape magnetic conductance yoke spare 10 that a ferromagnetic material is made is housed on this bearing.Two magnet strips 11 and 12 that have permanent magnet of these magnetic conductance yoke spare 10 supportings.On movable support 13, fix a magnetic conductance yoke spare 14, two magnet strips 15 and 16 that have permanent magnet of same installation above it.Need supporting and device driven 8 to be fixed on the movable support 13.Fixed magnet bar 11,12 and magnet strip 15,16 polarity that are installed on the movable support of facing 13 are made like this, make to produce a repulsion force between them.The side guiding of movable support 13 is born together with side guide strip 18 by director element 17, and the side guide strip is made of housing 4 in Fig. 1 and 2.
Linear electric motors 2 have a magnetic circuit 20 and the permanent magnet excitation device 19 that is fixed on above it that is fixedly mounted on the housing 4.A vertically disposed armature 5 that has the position changeable of winding 3 is arranged between them.This armature 5 is by linkage 6 and movable support 13 mechanical connections.
Its difference of structure by two kinds of embodiments of the supporting of Fig. 1 and Fig. 2 and drive system 1 is that the layout of critical element is different.Supporting system 7 is arranged on the below of linear electric motors 2 among Fig. 1, wherein installs 8 between supporting system 7 and linear electric motors 2, and they are interconnected.Be arranged on the below by Fig. 2 linear electric motors, and be connected with the supporting system 7 on opposite by linkage 6.Device 8 is installed in above supporting system 7 above the housing 4 of upward opening.
Next installs 8 and can be fixed on supporting and the drive system 1 by Fig. 3 and 4.The shape and the installment state of the housing 4 that is adopted here are significant.There is such possibility, device 8 is installed on the armature 5 of linear electric motors 2, perhaps will install 8 and be fixed on the bearing 13 of suspension by means of structure 22.The door that for example is fixed in both cases on the device 8 must move in the guide rail of itself, and wherein linkage should compensate mobile that door-suspension system occurs.
Do to such an extent that open downwards by the housing 4 that Fig. 3 is made up of aluminium extruded sections.Particularly the U-shaped section bar is because its intrinsic stability is suitable for such application scenario.Device 8 is contained on the armature 5 of linear electric motors 2.Independent director element 21 on the linkage 6 has increased armature 5 and has been suspended on the stability of the centre bearing of the device 8 above it.For flexible portability director element 17 and 21 is preferably made ball bearing.With being connected with the mechanical connecting device that does not draw in detail of second half, for example rope or belt carry out, and make second half opposite direction move.It is suitable that the bearing 13 of two suspensions is permanently connected.
Do to such an extent that upwards open by the housing 4 that Fig. 4 is made up of aluminium extruded sections, wherein the closure with a certain distance from the space has.Device 8 is connected with movable support 13 by a special structure 22.The connection of the single door that hangs can realize that cog belt and suspension bearing 13 are fixedly linked with cog belt.
Be suitable for adopting flat linear electric motors 2 as drive unit, it is contained in the below of housing 4 internal support systems 7 by its compact structure form.For the weight linear electric motors 2 that distribute best are fixed on the middle, below of supporting system 7.Linear electric motors 2 are controlled by electronic-controlled installation.Supply voltage is suitable for being lower than 60 volts, and rated current is about 3 amperes.Mobile distance is by means of a sensor measurement, and it is indicated a final position and can be used for chain function simultaneously.Mobile distance can be by means of magnetic increment type or analogue measurement systematic survey.
Linear electric motors 2 can differently be arranged with respect to supporting system 7.Described form of implementation relates to vertical layout.Schematically illustrated the layout that the side direction on supporting system 7 next doors in a kind of good structural concept staggers by Fig. 5.This linear synchronous motor 2 has the armature 5 of an iron-free.The electromagnetic excitation part only has the length of being determined by thrust, and the part/part of supporting permanent magnet has the length that mobile distance adds electromagnet portion.A short stator is realized motion, and short stator is made up of two phase windings that are installed on the bearing.If moving-mass is little, advantageous particularly then is because only used two phase windings.Therefore the rectifier of power supply also is a two-phase, thereby does cheaply.
Adopt such motor to make supporting and drive system 1 have good structure at assembly technique.Linear electric motors 2 flatly are installed in the next door of magnetic support system 7.Therefore linear electric motors 2 can be mounted and dismounted independently with respect to supporting system 7.This is not only in when operation, and especially has decisive meaning when being related to the repairing of changing motor, because only need dismantle linear electric motors 2.Because the air gap of supporting system 7 can be made to such an extent that can change by the design parameters of permanent magnet structure, even can guarantee also that when door tilts supporting system 7 moves non-contactly.Therefore the conclusive gap of door on the guide rail on the bottom surface can adapt with the application scenario.
Permanent magnet supporting system 7 is by the work of repulsion force principle.This action principle makes and can keep stable suspended state and do not need electrical adjustment devices.Do not need auxiliary energy in order to obtain suspended state.By utilization high energy magnet, for example neodymium iron boron (NdFeB) is because its high remanent induction can be than producing much higher force density with hard iron magnet.Therefore magnetic systems can be done to such an extent that physical dimension is little with high energy magnet when the supporting force of regulation, thereby saves the position.
By the change of the direction of magnetization, the spacing A of magnet strip and make the magnetic circuit optimization with the guiding of 10,14 pairs of magnetic flux of steel plate washer.With air gap L, the spacing between the just fixing and movable bearing 9 and 13 is different and change according to the principle supporting force.L is more little for air gap, and the supporting force that produces in supporting system 7 is big more.Relation between side-play amount and the power generally is non-linear.
According to the different adjacent magnets bars 11,12 of magnet arrangement and 15,16 distance A supporting force is played decisive influence.In Fig. 6 no matter be that the fixed bearing 9 or the adjacent magnets bar 11,15 of movable support 13 have the identical direction of magnetization.Secondly in two bearings 9 and 13 like pole towards air gap L.Here the distance A between the adjacent magnets bar 11 and 15 should be big as far as possible.
Among Fig. 7 for the repulsion force of necessity fixing with movable bearing 9 and 13 on same sex magnet strip 11,15 and 12,16 are provided with face-to-face, but south face is to air gap L in magnet strip 11 and 15, north pole face is to air gap L in another group magnet strip 12 and 16, and magnet distance A hour produces big supporting force when this layout.
If magnet strip 11,12,15,16 by steel plate washer 10,14 encirclements, make flux concentrating in the zone of air gap L, and supporting force can also further improve so.Here steel part 10,14 is made at side S and the magnetic conductance yoke spare on the magnet height H of the magnet strip 11,12,15,16 of air gap L dorsad.The raising of supporting force reaches by the optimization of magnet height H and side S.For the ferrous material that is used in the magnetic conductance yoke keeps few as much as possible, magnet strip 11,12 is embedded in the steel plate washer 10,14 to 15,16 flush.Obtain when about 2mm respectively according to the optimum structure of the different magnet height H of supporting force and side S.
