Abstract

It is known how to damp the rotation of rotating doors and similar access barriers by means of a discontinuous gear train in that preferably noncircular gears first convert the continuous door rotation into a discontinuous rotation on the output side and said discontinuous rotation is damped by means of a damping element. Known arrangements use gears having identical rolling curves for this purpose, which leads to an overshoot of the rotation and to intermittent damping action. This should be improved by the invention. Said aim is achieved by a damping unit that uses two noncircular gears having different rolling curves, of which one is egg shaped and the other in contrast is shortened and at the same time widened relative to the first. This results in a modified damping profile that enables more uniform motion of the revolving door. This arrangement also enables a motor drive, which can be operated at a constant rotational speed because of the arising sine- or cosine-shaped inverse curve of the gear train and which enables a clean end-position motion of the driven access barrier.

Description

Be used for cushioning discontinuously the buffer that rotatablely moves

The present invention relates to a kind of buffer, described buffer is used for cushioning discontinuously rotatablely moving of the driven wheel (the particularly driven wheel of entrance blocking device) that can rotate around driving axis by means of discontinuous transmission device, and described transmission device is made of two intermeshing, eccentric support, non-circular gears and described driven wheel is linked to each other with the buffer element that sets to output shaft.

The sort buffer device is formerly known by German laid-open document DE3638353A1.The continuous rotation of the end of the elbow movable joint that connects with door closer here is converted to discontinuous rotation by the transmission device that is comprised of two identical noncircular gears, and this discontinuous rotation is finally cushioned.

In this door closer, but in the entrance blocking device that particularly in personnel's separating device, adopts, usually make entering of shielded zone depend on a condition, for example depend on whether show effective admission ticket.Therefore this entrance blocking device makes the locking device kayser after at every turn by a people, thereby can not allow a plurality of people enter shielded zone with an effective admission ticket.Triggered mechanical caging to the entrance blocking device by this kayser, this locking prevents from continuing rotation.If the entrance blocking device moves to terminal location with the speed that does not reduce, then the kayser of locking mechanism makes material be subject to strong load on the one hand, means on the other hand the generation noise pollution.It is negative qualitative character that the noise that produces like this in the zone of entrance blocking device also allows the people feel usually, thereby also has the demand of avoiding this situation aspect manufacturer.

In other words, similarly in the device like this during buffering, wish in the zone of terminal location, to be buffered into by this way the motion of atretostomia device: so that realize soft but smoothly terminal location operation at entrance blocking device, door closer or other in principle.Continuous rotatablely moving can only be carried out when direct buffering equably, thereby door is because buffering just becomes heavy, certainly just can move comparatively like a cork at the extreme point of buffering piston deflection.Because cushioning effect is relevant with rotary speed, large rotary speed means high buffering here, and little rotary speed means little buffering, therefore must realize the gradually speed of raising in order to cushion in the zone of terminal location.This is by realizing with discontinuous transmission device, and described discontinuous transmission device is configured to so that after unstable (labil) position to being about to realize ever-increasing rotary speed before the incoming terminal position.

By the open source literature that provides above formerly known gear configurations become identical, but such shortcoming is arranged when converting continuous rotatablely moving to discontinuous rotatablely moving, that is, because the identical structure of each gear must stand is to deviate from significantly desirable buffer curve.Therefore prior art also is devoted to obtain to realize other possibilities of desirable as far as possible buffer curve.For this reason by the known a kind of locking device that is used for turnsile equipment of for example Germany Patent document DE102007010385B4.This turnsile equipment consists of a kind of possible scheme of entrance blocking device, wherein is provided with blocking element, and described blocking element is provided with the separating device on the space.By the stair step of blocking element, each so that a people can pass through the entrance blocking device, realized thus personnel's separation.In the open scope of this Germany Patent document, the stepping of blocking element realizes by motor, controls so described motor: so that in the terminal area of motion, in the zone of the terminal location of blocking element buffering is set in other words.Make decelerating through motor in the zone of terminal location, motor can not swing and cross terminal location thus, thereby has realized described buffering.

For various reasons, for example for reducing noise, explosion-proof reason, perhaps also may be because a kind of solution of the machinery than electronic unit longer service life will be provided to client, also have the demand for the entrance blocking device of Purely mechanical, but this entrance blocking device should have in corresponding good buffering qualitatively.Here, use under the ideal situation and identical as far as possible product solution structurally in vehicularized scheme, reequip or lean production in order to can realize.

Therefore the object of the invention is to, a kind of buffer for strengthening continuously the terminal location buffering that rotatablely moves is provided, described buffer makes it possible to achieve desirable as far as possible buffer curve, and does not have swing And can abandon using simultaneously motor.

Described purpose realizes by the buffer by the feature of claim 1.The favourable form of implementation of other of described buffer can be by drawing in the dependent claims.

Structurally, at first have driven wheel, the entrance blocking device is used on the described driven wheel with its masterpiece.The driven wheel that utilization is supported revolvably around driving shaft with the transmission of torque of the motion of entrance blocking device to buffer.If be alternative in this motor is set, black box at first is set here, described black box should be brought into play the effect identical with motor in the described control in the above.Proved creationary solution is for this reason, for black box discontinuous drive unit is set, and the entrance blocking device that the rotation that described drive unit will be caused by current people produces or the continuous rotation of driven wheel convert discontinuous rotation to.On final effect, the discontinuous motion that produces the driving shaft of identical discontinuous transmission device owing to the continuous rotation of the driving shaft of the discontinuous transmission device that adopts thus.Now the output shaft speed that is buffered in of the velocity correlation on output shaft causes strong buffering when higher, and the speed that driving shaft is less is then brought less buffering.

The discontinuous transmission device that for this reason adopts comprises two non-circular gears, and described gear has different rolling curves

Can determine, be arranged on the rolling curve that gear on the driving shaft preferably can have the egg shape, and another non-circular gear that is installed on the output shaft shortens in the direction of extreme value with respect to the gear of driving side, opposite widening in a lateral direction in described direction.The distribution of this rolling curve particularly produces obviously more gradual rate curve as the system responses that applies continuous rotation at output shaft with respect to the situation of the rolling curve that adopts identical for example egg shape on output shaft.This causes more clearly terminal location operation and uniform damping characteristics during rotation, has realized thus and the independence of Negotiation speed, and controlled terminal location operation always occurs under described Negotiation speed.

One be not particularly preferred, particularly in service at terminal location and in the zone of unstable position relatively poor configuration realize by exchanging two gears, the gear that will widen and shorten in other words is arranged on the driving shaft.But also explicitly call for this technical scheme of protection here.

Two non-circular gears advantageously are designed to respectively symmetrical, thereby the rotation of entrance blocking device can be carried out along both direction.Here dead-center position, and unstable equilibrium is arranged in such position of gear in the position of rotation of centre, in this position, its axis of symmetry overlaps each other.Preferred two gears have the identical number of teeth, in order to allow along identical direction Multiple through then out.

Advantage according to the identical rolling curve of prior art is, only need to make an instrument for the manufacturing of identical gear.Because the cost of this instrument, this is a very important advantage, because this advantage can be stood bad revolving property.But the present invention has adopted MIM or CIM parts for this reason, so that it is lower to be kept for the cost of instrument.The cost of the required instrument instrument more required than traditional this metal gear hangs down several times thus.

The buffering of output shaft can be undertaken by the motor that also is arranged on here according to the present invention, described motor with the beginning described electric machinery like mode and form control.If adopt by the known discontinuous transmission device with two identical gears of prior art, then adopt a motor that is used for drive transmission to cause identical rate curve to distribute at the outlet side of reality, this means, the rotation that motor is constant so that revolving door rotate like this: it is this that to be rotated in unsettled centre position very quick.This motor must intricately control so that the function of its motion during corresponding to constant rotation ends at driving side.In addition, motor must be set to stronger than power under the normal conditions.On the contrary, become by its form design according to transmission device of the present invention, so that inverse function is SIN function or cosine function, thereby when motor speed is constant, automatically realize accelerating and running slowly, in other words, reach the highest speed at the peak value place of motion.Therefore both be suitable for or be designed for motor by constant rotation carrying out motor driven and driving according to buffer of the present invention, and also be suitable for or be designed for manual operation, in motor-driven situation, the function of driving shaft and power transmission shaft exchanges.In other words, motor acts on the output shaft, and realizes the rotation of entrance blocking device by discontinuous transmission device.Transmission device guarantees here that according to design of the present invention the characteristic of transmission device is identical on two traffic directions, and the inverse function on output shaft is sine or cosine function when applying constant motor speed at output shaft in other words.Thereby owing to needing equally less power for accelerating and slowing down, can use motor less on the power, the motor that this motor is stronger with respect to power is saved cost.

Determining of desirable buffering function can be by the gear connecting rod transmission device

Realize, its mode is, determines starting torque in the settling position, i.e. so-called holding torque by changing bent axle spacing in the gear connecting rod transmission device.Can read sine or cosine function as inverse function by bent axle integrated in the gear connecting rod transmission device, described sine or cosine function can bring advantage described above for motor-driven operation.Determined function and inverse function are delivered on two non-circular gears now because with the use with discrete transmission device of two gears according to the present invention, therefore the assembling of gear connecting rod transmission device is obviously more difficult, and is expensive.But comprise clearly the situation that the transmission device with noncircular gear of the present invention uses the gear connecting rod transmission device that substitutes here.

Set in another form of implementation, output shaft is equipped with the bent axle element, thereby the buffer element that for example is configured to the spring buffer element can be realized eccentric being connected with output shaft.The sort buffer element for example can advantageously be integrated in the gas spring, and described gas spring comprises piston and cylinder.When piston moves in cylinder or from the cylinder cathetus, relevant motion is cushioned, thereby by piston with eccentric manner for example via being connected of described bent axle element and output shaft, but alternatively also can be directly and being connected of discontinuous drive unit, can realize the buffering of wishing.

In order further to avoid in cross the swinging and setting of terminal location, when being in stable equilibrium state, discontinuous transmission device and spring element reach the terminal location of driven wheel.This means, discontinuous transmission device is in the zone of the rapid movement of output shaft, and piston is in its position without potential energy.Here, set in addition, piston only shifts out the direction buffering along a direction, particularly edge, thereby along opposite direction, the motion that namely particularly when moving into, can not cushioned.For this reason, the piston of gas spring for example has corresponding valve.Also on described direction, do not cushion thus by the valve opening of described valve running of hydraulic power oil by piston.

But also can make on the contrary without any problems the action direction counter-rotating, thereby gas spring only cushions when moving into, this situation also should comprise in the present invention clearly.Equally also can when moving into and shifting out, all cushion, although this is not preferred scheme.

For this reason can example as being designed to the additional reposition element of back-moving spring form, be used for making the entrance blocking device never settling position get back to terminal location, when for example the edge opposite direction is left again after the entrance blocking device is beginning rotation.All the time reset towards nearest next terminal location for this reason, when the rotation that has begun with box lunch stops, can not cause undesirable whole circle rotation.

In order in the use of sort buffer device, to obtain large as far as possible degree of freedom, the output shaft that setting substitutes at discontinuous transmission device arranges simply, only allows and the eccentric bent axle that is connected of buffer element, use crankshaft disk, described crankshaft disk is provided with fixed mechanism for buffer element in its periphery with distributing, and described fixed mechanism has different eccentricity.If adopt the tooth axle as driving shaft and/or output shaft, then fixed mechanism be arranged on the tooth axle on the identical quantity of tooth distribute around the point of rotation.Crankshaft disk can be equipped on each position of fixed mechanism by rights thus.Can again adjust thus the degree of buffering, particularly in the entrance blocking device of the different size with the big or small quality of difference, adjust individually the degree of buffering.Except the possibility of intense adjustment, also there is thus such possibility, namely carry out adaptively for various product, for example have turnsile, revolving door of different calibration etc.

Additional buffering in addition can be achieved like this, that is, discontinuous transmission device is contained in the housing, and described housing is filled with transmission device machine oil.Guaranteed thus the mild operation of discontinuous transmission device, this is a kind of impact mitigation measure, and the sort buffer measure is worked to the whole continuous rotation of driven wheel equably.

Another integrated step realizes like this, that is, the driving shaft that is connected with the driven wheel effect and cushioning effect output shaft are thereon made integratedly with affiliated noncircular gear respectively.Together with the ball bearing that adopts, need to be no more than eight parts for whole non-circular transmission device thus, described ball bearing is bearing in noncircular gear for this reason in the housing that arrange, double type together with each axle.It is very simple and very economical that the assembling of this non-circular transmission device has proved.

As previously described, the sort buffer device should be able to be used for series of products, particularly can be used for having revolving door and the turnsile of different calibration.When turnsile had 90 ° calibration, driven wheel needed the gearratio of 1:4 towards the direction of entrance blocking device, thereby turnsile rotation 1/4th circles are so that driving shaft or whole circle of output shaft rotation.

Driving shaft is also carried out the rotation of a whole circle here, thereby because discontinuous transmission device is realized fast motion at first successively, then is the zone of microinching, then is again rapid movement.The zone that has in other words two rapid movements wherein can be determined, it is stronger when being buffered in rapid movement that buffer element is realized, thereby in traditional cushion dashpot, described in fact these two zones are subject to stronger buffering.But because buffer element is only along a directive effect, only just significantly cushion during the rapid movement of explanation in the back, this zone is arranged in the zone of the terminal location of turnsile.Because the spring pressure of buffer element has been set up stable terminal location operation here.When the gearratio of 1:3 or 1:2 is set, can be used for 120 ° of calibration or also can be used for 180 ° of calibration by the identical device of other gearratio.

Because described discontinuous transmission device usually is enclosed in the housing and needs the such orientation of discontinuous transmission device, in order to the moment of maximum cushioning is placed the stub area of motion, reasonably be that the tram of discontinuous transmission device in housing guaranteed in the employing measure.Be configured to partly the tooth axle on driving shaft or the output shaft, thereby for output shaft, the bent axle element can be sleeved on directly on the tooth axle, and for driving shaft, speed changer or driven wheel can be sleeved on directly on the tooth axle for this reason.Here especially reasonably be that the tooth that speed change gear or driven wheel have is many times in the tooth axle.Guaranteed in this case, in each position of change-speed gearing or driven wheel, can carry out correct adjustment.

But addedly set, be provided for the mark of the tram of discontinuous transmission device at the tooth axle.

An optional form of implementation according to buffer, driven wheel is configured to such gear, described gear is engaged in tooth bar or the flat-toothed belt, this form of implementation allows to be arranged in the zone of wall section and described gear when making the driven wheel rotation when tooth bar or flat-toothed belt, uses described buffer as the buffer for translation door.Driven wheel is such reduction of speed when needed, so that the rotation corresponding to the once whole circle of driving shaft is opened in complete passing, in the ideal case, not to tend to occur fully complete rotation, thereby reach initial position when also also arriving thus the situation of torque maximum in the maximum position of buffering, and close reliably door.If slightly the centre position is crossed in the door movement towards the direction that opens or closes, then door then can be moved to by the spring buffer element voluntarily with promoting and open or close accordingly the position.

Identical situation also be applicable to will be relevant buffer be used for the situation of double-open swinging door, in this case, along the direction of opening of door rack rails is set, described rack rails is engaged to driven wheel or sets in the gear to driven wheel.Here also can use speed changer when needed.

The below explains foregoing the present invention in detail according to embodiment.

Fig. 1 illustrates the buffer 10 according to prior art, and described buffer particularly is applicable to be buffered into rotatablely moving of atretostomia device.Rotatablely moving of entrance blocking device acts on the speed change gear that is not shown specifically here, and wherein will rotatablely move is delivered on the driven wheel 13.Driven wheel 13 is installed on the driving shaft 15, and driving shaft 15 is connected with discontinuous transmission device, and described transmission device comprises two identical, non-circular gears 11 and 12.Because the rolling curve of the egg shape of

gear

11 and 12, continuous the rotatablely moving of entrance blocking device converts discontinuous rotatablely moving on the output shaft 16 to, and described output shaft is connected with buffer element 17,18.Because identical rolling curve, do not need to make a plurality of for these two

gears

11,12 instrument, thereby make

gear

11,12 required costs keep lower.But the rolling curve of realizing thus is not desirable, because this rolling curve is conducive to centre position buffering and the buffering inaccuracy of position endways.The still very obvious unsettled position in this zone.

Fig. 2 illustrates according to solution of the present invention, and this solution has identical structure basically, but two gears 11 have different rolling curves with 12.Therefore, the rolling curve of the gear 11 of driving side is egg type basically, and the rolling curve of the gear 12 of outlet side shortens with respect to the rolling curve of the gear 11 of the driving side direction along extreme value, but horizontal direction is in the direction widened.Thus two

gears

11,12 have identical girth and so that the rotary speed that can on output shaft 16, produce have Utopian distribution and realize thus buffering.

This piston 18 that acts on the output shaft 16 by gas spring 17 realizes, described piston is connected with output shaft 16 by bent axle element 14.Convert discontinuous rotatablely moving to rectilinear motion thus, described rectilinear motion is by gas spring 17 bufferings.17 of gas springs cushion when piston 18 shifts out, thus at the complete gas spring 17 that revolves when turning around of output shaft 16 just in the second half districts, after piston 17 moves in the cylinder of gas spring 17 fully, begin to cushion in other words.In other words, if use sort buffer, by shown in terminal location set out, the rotation of the entrance blocking device that links to each other with driven wheel 13 is until the rotation of half finishes the carrying out do not cushioned before.But buffering works with piston 18 with shifting out velocity correlation, thereby because discontinuous motion, buffering is distinguished until the terminal point of approaching rotation works to whole system more and more since the second rotation half based on the kinematic design of discontinuous transmission device, enough strong buffering occurs in the land thus, occured to swing and it can be stopped in the zone of its terminal location in order to prevent the entrance blocking device.

Fig. 3 shows according to ideal curve 51, according to the curve 50 of the solution of prior art with according to the figure line of curve of the present invention, has drawn in the figure the curve of piston speed about the anglec of rotation of the gear 12 of outlet side.Consider two

gears

11,12 symmetry,

curve

50,51 and 52 is symmetrical curves, and its symmetry consists of the point symmetry around zero point when being formed in rotation π.Ideal curve 51 is illustrated near the symmetric points 53 the zone has slope steeper and substantial constant, this means in this zone and cushions uniformly.At symmetric points 53 places, system reaches unsettled balance, and under this equilibrium state, piston speed has flex point.By high velocity variations avoided the entrance blocking device therebetween the position owing to the reason of friction may be stuck.Same situation also is applicable to utilize the curve 52 of realizing according to gear of the present invention.Only have the curve that utilizes identical gear to realize of reflection prior art to have piston speed variation too small on slope, this means temporary transient deceleration and acceleration, this deceleration and acceleration are because the damping characteristics of piston 18 causes centre position buffering at the volley.The height of buffering or piston speed is put curve 50 that also Billy realizes with identical gear further towards the direction skew of terminal location in the situation of the curve 52 that utilizes gear of the present invention to realize, this can cause more clearly that terminal location moves.

Promote transmission device if not the people by the entrance blocking device, and the motor that is mounted in outlet side drives it, then transmission device according to the present invention guarantees to realize the inverse curve 54 according to Fig. 4, and this curve obtains sine or cosine curve at driving side or in entrance blocking device one side.In other words, this design is so that can be used for identical transmission device manually operation and motor-driven operation, wherein in the situation that motor-driven operation, needn't implement complicated control method to motor, but it is moved under constant rotating speed, in order to guarantee the suitable motion of entrance blocking device, namely realize clearly Accelerating running and run slowly.

Arrangement according to Fig. 5 illustrates buffer 10, and the driving shaft 13 of this buffer links to each other with turnsile 20 by speed changer 21.This turnsile 20 can use together with identical buffer 10, and is identical with revolving door or similar devices.Another bent axle element 14 only need to be set or in the situation that use crankshaft disk to select another eccentricity, in order to when buffering, the larger quality of revolving door is paid attention to here.Owing to shown 120 ° calibration, selected the gearratio of 1:3 here.If for example should adopt the turnsile 20 with 2 or 4 locking fences, then only need to make gearratio suitable therewith, namely in the situation that two five equilibriums adopt the gearratio of 1:2, in the situation that the quartering adopts the gearratio of 1:4.In the situation of the gearratio of selecting 1:3, when the complete circle of turnsile 20 rotations, driving shaft 16 rotations three times are namely crossed the buffering maximum point three times, namely cross the buffering maximum point at every turn by turnsile 20 time.

According to the view of Fig. 6, also set the present invention for double-open swinging door 30.Be provided with rack rails 31 in the zone of the wall of double-open swinging door 30 outsides, rack rails directly is engaged in the driven wheel 13 and is placed on thus rotation.The size of driven wheel 13 is selected in this case like this, that is, open fully corresponding to the complete circle of driven wheel 13 rotations.In other words, double-open swinging door 30 is swing open at first, the complete circle of driven wheel 13 rotations this moment.Along opposite direction buffering is set also in the zone of terminal location.To be noted herein that the buffering in order realizing ideal, not carry out the rotation of whole circle, therefore be similar to the rotation that has realized from the buffering maximum point to the buffering maximum point.This always shows impracticablely when moving back and forth, but then is not this situation in two-way use turnsile 20.Need to not take closing organ with certain making every effort to overcome this moment yet, but only in the terminal location operation, in order to for example allow the automatic clamping of locking ratchet.

At last, Fig. 7 illustrates another embodiment, has wherein realized sliding door 40.According to foregoing content, the tooth bar 41 that is parallel to the wall installation here is engaged in the transmission device that sets to driven wheel 13, thereby also realizes buffering by buffer 10 here when sliding door 40 is opened fully.Therefore buffering is also carried out so here, so that sliding door arrives its terminal location under buffering.

Therefore, the front has illustrated a kind of for cushioning discontinuously the buffer that rotatablely moves, and described buffer particularly can be used for entrance blocking device field.By continuous rotation being converted to the discontinuous rotation that is suitable for cushioning, sort buffer can carry out in the selected zone that rotatablely moves, thereby particularly realizes realizing cushioning towards the zone of terminal location with raising.Desirable buffer curve realizes by the gear that employing has different rolling curves, and the gear of outlet side gear with respect to driving side on the direction of its eccentricity shortens here, and it is widened relatively in a lateral direction.
