Known how by the rotation of discontinuous transmission device buffering revolving door and similar entrance blocking device, its mode is the discontinuous rotation first by non-circular gear, continuous print door being converted to outlet side, and this discontinuous buffer element that is rotated through cushions.Known arrangement uses the gear with identical rolling curve for this reason, and this can cause crossing of rotation swing and cause centre position to be cushioned.This situation should be improved by the present invention.Described object is realized by a kind of buffer, and wherein use two gears with not identical rolling curve, one of them gear is egg type, and another gear shortens relative to the first gear and adds simultaneously in contrast and broadly forms.The buffer curve be improved thus, described buffer curve makes the motion of revolving door more even.Same this arrangement form also allows the drive unit using electric motor type, the inverse curve for the sine that adjusts or cosine-shaped that this drive unit occurs due to transmission device and running with constant rotating speed, and run at the terminal location clearly making it possible to achieve the entrance blocking device driven.
Description
Technical field
The present invention relates to a kind of buffer, described buffer is used for the rotary motion cushioning the driven wheel (particularly the driven wheel of entrance blocking device) that can rotate around driving axis by means of discontinuous transmission device discontinuously, described transmission device by two engage each other, eccentric support, non-circular gear forms and described driven wheel is connected to the buffer element of output shaft with arranging.
Background technology
This buffer is formerly known by German laid-open document DE3638353A1.Here be rotated through the transmission device be made up of two identical noncircular gears with the continuous print of the end of the elbow movable joint that door closer connects and be converted to discontinuous rotation, this discontinuous rotation is finally cushioned.
In this door closer, but in the entrance blocking device particularly adopted in personnel's separating device, usually make entering of shielded region depend on a condition, such as, depend on and whether show effective admission ticket.Therefore this entrance blocking device makes locking device kayser after at every turn by a people, thus multiple people can not be allowed to enter shielded region with an effective admission ticket.Trigger the mechanical caging to entrance blocking device by this kayser, this locking prevents from continuing to rotate.If entrance blocking device moves to terminal location with the speed do not reduced, then the kayser of locking mechanism makes material be subject to strong load on the one hand, means generation noise pollution on the other hand.The noise produced like this in the region of entrance blocking device also allows people feel it is negative qualitative character usually, thus in manufacturer, also there is the demand avoiding this situation.
In other words, when cushioning like this in entrance blocking device, door closer or other similar devices in principle, wish the motion being buffered into atretostomia device in the region of terminal location by this way: make to realize soft but smoothly terminal location run.Continuous print rotary motion can only be carried out equably when directly cushioning, thus door just becomes heavy due to buffering, certainly just can run comparatively like a cork at the extreme point of buffering piston deflection.Because cushioning effect is relevant to rotary speed, rotary speed large here means high buffering, and little rotary speed means little buffering, therefore in order to carry out cushioning the speed that must realize improving gradually in the region of terminal location.This is by using discontinuous transmission device to realize, and described discontinuous transmission device is configured to, and makes to realize ever-increasing rotary speed to by before incoming terminal position after unstable (labil) position.
Become identical by the gear configurations that the open source literature provided is formerly known above, but there is such shortcoming when converting continuous print rotary motion to discontinuous rotary motion, that is, what must stand due to structure that each gear is identical is deviate from desirable buffer curve significantly.Therefore prior art is also devoted to obtain other possibilities realizing buffer curve desirable as far as possible.For this reason by the known a kind of locking device for turnsile equipment of such as Germany Patent document DE102007010385B4.This turnsile equipment forms a kind of possible scheme of entrance blocking device, and be wherein provided with blocking element, described blocking element is provided with separating device spatially.By the stair step of blocking element, make a people by entrance blocking device, personnel's separation can be thus achieved at every turn.In the open scope of this Germany Patent document, the motor that steps through of blocking element realizes, and controls described motor like this: make, in the terminal area of motion, to arrange buffering in other words in the region of the terminal location of blocking element.In the region of terminal location, make decelerating through motor, motor can not sway across terminal location thus, thus achieves described buffering.
For various reasons, such as reduction noise, explosion-proof reason, or also may owing to will provide a kind of solution of the machinery than electronic unit longer service life to client, also there is the demand of the entrance blocking device for Purely mechanical, but this entrance blocking device should have in corresponding buffering well qualitatively.Here, ideally use and products scheme structurally identical as far as possible in vehicularized scheme, repacking or lean production can be realized.
Summary of the invention
Therefore the object of the invention is to, provide a kind of for strengthening the buffer cushioned the terminal location of rotary motion continuously, described buffer makes it possible to achieve buffer curve desirable as far as possible, and does not have swing
and can abandon using motor simultaneously.
Structurally, first there is driven wheel, entrance blocking device is used on described driven wheel with its masterpiece.Utilize the driven wheel that supports revolvably around driving shaft by the transmission of torque of the motion of entrance blocking device to buffer.If be alternative in this to arrange motor, first arrange black box here, described black box should play the effect identical with the motor in control recited above.Proved creationary solution is arrange discontinuous drive unit for black box for this reason, and the continuous print of the entrance blocking device that the rotation caused by the people passed through produces by described drive unit or driven wheel converts discontinuous rotation to.On final effect, produce the discontinuous motion of the driving shaft of identical discontinuous transmission device thus due to the continuous print rotation of the driving shaft of adopted discontinuous transmission device.Velocity correlation now on output shaft be buffered in output shaft speed higher time cause strong buffering, the speed that driving shaft is less then brings less buffering.
The discontinuous transmission device for this reason adopted comprises two non-circular gears, and described gear has different rolling curves
can determine, the gear arranged on the driving shaft preferably can have the rolling curve of egg-shaped, and another is arranged on the non-circular gear on output shaft relative to the gear of driving side and shortens in the direction of the extreme, widening in a lateral direction on the contrary in described direction.The distribution of this rolling curve is particularly relative to adopting the situation of the rolling curve of identical such as egg-shaped to produce obviously more gradual rate curve as the system responses applying continuous print rotation on output shaft on output shaft.This causes terminal location more clearly to run and during rotation uniform damping characteristics, thus achieves the independence with Negotiation speed, controlled terminal location always occurs under described Negotiation speed and runs.
One be not particularly preferred, particularly terminal location run in and configuration poor in the region of unstable position realize by exchanging two gears, in other words by widen and shorten gear setting on the driving shaft.But also explicitly call for this technical scheme of protection here.
Two non-circular gears are advantageously designed to symmetrical respectively, thus 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 coincides with one another.Preferably two gears have the identical number of teeth, to allow along identical direction Multiple through then out.
Advantage according to the identical rolling curve of prior art is, the manufacture for identical gear only needs manufacture instrument.Due to the cost of this instrument, this is a very important advantage, because this advantage can stand bad revolving property.But present invention employs MIM or CIM parts, so that the cost being kept for instrument is lower for this reason.The cost several times lower than the instrument needed for traditional this metal gear of instrument required thus.
The buffering of output shaft can be undertaken by the also motor be arranged on here according to the present invention, described motor with mode and form control like the electric machinery described in beginning.If adopt by the known discontinuous transmission device with two identical gears of prior art, a motor for drive transmission is then adopted to cause identical rate curve distribution at the outlet side of reality, this means, the constant rotation of motor makes revolving door rotate like this: this to be rotated in unstable centre position very quick.This motor must intricately control, and makes its motion end at driving side corresponding to function during constant rotation.In addition, motor must be set to stronger than power under normal conditions.On the contrary, transmission device according to the present invention is become by its form design, makes inverse function be SIN function or cosine function, thus accelerates in the permanent timing automatic realization of motor speed and run slowly, and in other words, reaches the highest speed at the peak value place of motion.Therefore be both suitable for according to buffer of the present invention or be designed for carrying out motor driven driving by the motor of constant rotation, and be also 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 output shaft, and realizes the rotation of entrance blocking device by discontinuous transmission device.Transmission device, according to design of the present invention, guarantees that the characteristic of transmission device is identical on two traffic directions here, and the inverse function in other words when applying constant motor speed on output shaft on output shaft is sinusoidal or cosine function.Thus less of the power accelerated and slow down owing to needing equally, can use motor less on power, cost saved by the motor that this motor is stronger relative to power.
The determination of desirable damping function can by gear connecting rod transmission device
realize, its mode is, determines the starting torque in settling position, i.e. so-called holding torque by the bent axle spacing changed in gear connecting rod transmission device.Can read sinusoidal or cosine function by bent axle integrated in gear connecting rod transmission device as inverse function, 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, the assembling of gear connecting rod transmission device is obviously more difficult, and is therefore expensive.But comprise the situation that the alternative transmission device with noncircular gear of the present invention uses gear connecting rod transmission device here clearly.
Set in another form of implementation, output shaft is equipped with bent axle element, thus the buffer element being such as configured to spring buffer element can realize eccentric connection with output shaft.This buffer element such as can advantageously be integrated in gas spring, and described gas spring comprises piston and cylinder.When piston is in cylinder or from cylinder linear movement, relative motion is cushioned, thus by piston with eccentric manner such as via the connection of described bent axle element and output shaft, but alternatively also can directly with the connection of discontinuous drive unit, can realize the buffering of hope.
Setting to avoid further the crossing swing of terminal location, reaching the terminal location of driven wheel when discontinuous transmission device and spring element are in stable equilibrium state.This means, discontinuous transmission device is in the region of the most rapid movement of output shaft, and piston is in it without in the position of potential energy.Here, set in addition, piston only cushions along shifting out direction along a direction, particularly, thus along contrary direction, namely particularly can carry out the motion do not cushioned when moving into.For this reason, the piston of gas spring such as has corresponding valve.Also do not cushioned in said direction thus by the valve opening of described valve running of hydraulic power oil by piston.
But also can action direction be made on the contrary to reverse without any problems, thus gas spring only cushions when moving into, this situation also should comprise in the present invention clearly.Equally also in immigration and all can cushion when shifting out, although this is not preferred scheme.
The additional reposition element being such as designed to back-moving spring form can be used for this reason, for make entrance blocking device never settling position get back to terminal location, such as, when entrance blocking device again leaves in reverse direction after starting to rotate.All the time reset towards nearest next terminal location for this reason, during the terminating rotation started with box lunch, undesirable whole circle can not be caused to rotate.
In order to obtain degree of freedom large as far as possible in the use of this buffer, setting substitutes and arranges simply on the output shaft of discontinuous transmission device, only allows the bent axle that be connected eccentric with buffer element, use crankshaft disk, described crankshaft disk is provided with the fixed mechanism for buffer element with distributing on their outer circumference, and described fixed mechanism has different eccentricity.If adopt tooth axle as driving shaft and/or output shaft, then fixed mechanism distributes around the point of rotation with the quantity identical with the tooth be arranged on tooth axle.Crankshaft disk can be disposed in each position of fixed mechanism by rights thus.Again can adjust the degree of buffering thus, particularly have different size quality different size entrance blocking device in adjust the degree of buffering individually.Except the possibility of intense adjustment, also there is such possibility thus, namely carry out adaptation for various different product, such as, there is the turnsile of different calibration, revolving door etc.
Additional buffering in addition can be achieved like this, that is, discontinuous transmission device holds in the housing, and described housing transmission device machine oil is filled.Thus ensure that the mild operation of discontinuous transmission device, this is a kind of impact mitigation measure, and this impact mitigation measure rotates the whole continuous print of driven wheel equably and works.
Another integrated step realizes like this, that is, the driving shaft be connected with driven wheel effect and cushioning effect output shaft are thereon made integratedly with affiliated noncircular gear respectively.Thus together with adopted ball bearing, need to be no more than eight parts for whole non-circular transmission device, noncircular gear is bearing in housing that for this reason arrange, double type together with each axle by described ball bearing.The assembling of this non-circular transmission device has proved very simple and very economical.
As previously described, this buffer should be able to be used for series of products, particularly may be used for revolving door and the turnsile with different calibration.When turnsile has the calibration of 90 °, driven wheel needs the gearratio of 1:4 towards the direction of entrance blocking device, thus turnsile rotates 1/4th circles makes driving shaft or output shaft rotate a whole circle.
Driving shaft also performs the rotation of a whole circle here, thus due to discontinuous transmission device, realizes first successively moving fast, and being then the region of microinching, is then again rapid movement.In other words there is the region of two rapid movements, wherein can determine, comparatively strong during what buffer element realized be buffered in rapid movement, thus in traditional cushion dashpot, described in fact these two regions are subject to stronger buffering.But because buffer element is only along a direction effect, just significantly cushion during the rapid movement only illustrated below, this region is arranged in the region of the terminal location of turnsile.Due to the spring pressure of buffer element, establish stable terminal location here and run.When arranging the gearratio of 1:3 or 1:2, may be used for 120 ° of calibration by the device that other gearratio is identical or also may be used for 180 ° of calibration.
Because described discontinuous transmission device surrounds in the housing and the orientation needing discontinuous transmission device so usually, to be placed in the stub area of motion the moment of maximum cushioning, reasonably, discontinuous transmission device tram is in the housing guaranteed in employing measure.Be configured to tooth axle partly on driving shaft or output shaft, thus for output shaft, bent axle element directly can be sleeved on tooth axle, and for driving shaft, speed changer or driven wheel can directly be sleeved on tooth axle for this reason.Here especially reasonably, the tooth that speed change gear or driven wheel have is many times in tooth axle.Ensure that in this case, can correct adjustment be carried out in each position of change-speed gearing or driven wheel.
But addedly set, tooth axle arranges the mark of the tram being used for discontinuous transmission device.
According to an optional form of implementation of buffer, driven wheel is configured to such gear, described gears meshing is in tooth bar or flat-toothed belt, this form of implementation allows, when tooth bar or flat-toothed belt are arranged in the region of wall portion and described gear makes driven wheel rotate, to use described buffer as the buffer for translation door.Driven wheel when needed can reduction of speed like this, complete passing is made to open the rotation of the once whole circle corresponding to driving shaft, in the ideal case, not tend to completely complete rotation occurs, thus reach initial position when cushioning maximum position and also arriving the situation of torque maximum thus, and reliably close door.If slightly door is moved across centre position towards the direction opened or closed, then door then can be moved to by spring buffer element voluntarily and open or close position accordingly with promoting.
Identical situation is also applicable to the situation relevant buffer being used for double-open swinging door, and in this case, the opening direction along door arranges rack rails, and described rack rails is engaged to driven wheel or arranges in the gear of driven wheel.Here also speed changer can be used when needed.

Detailed description of the invention
Fig. 1 illustrates the buffer 10 according to prior art, and described buffer is particularly applicable to the rotary motion being buffered into atretostomia device.The rotary motion of entrance blocking device acts on a speed change gear be not shown specifically here, wherein rotary motion is delivered on driven wheel 13.Driven wheel 13 is arranged on 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.Due to the rolling curve of the egg-shaped of gear 11 and 12, the continuous print rotary motion of entrance blocking device converts discontinuous rotary motion on output shaft 16 to, and described output shaft is connected with buffer element 17,18.Due to identical rolling curve, do not need to manufacture multiple instrument for these two gears 11,12, thus the cost manufactured needed for gear 11,12 keeps lower.But rolling curve realized thus is not desirable, because this rolling curve is conducive to centre position buffering and in the buffering inaccuracy of terminal position.The position still obviously unstable in this region.
Fig. 2 illustrates that, according to solution of the present invention, this solution has identical structure substantially, but two gears 11 and 12 have different rolling curves.Therefore, the rolling curve of the gear 11 of driving side is egg type substantially, and the rolling curve of the gear 12 of outlet side shortens along the direction of extreme value relative to the rolling curve of the gear 11 of driving side, but horizontal direction is in the direction widened.Two gears 11,12 have identical girth and the rotary speed making it possible to produce on output shaft 16 has Utopian distribution and realizes buffering thus thus.
This is realized by the piston 18 acted on output shaft 16 of gas spring 17, and described piston is connected with output shaft 16 by bent axle element 14.Convert discontinuous rotary motion to rectilinear motion thus, described rectilinear motion is cushioned by gas spring 17.Gas spring 17 only cushions when piston 18 shifts out, thus output shaft 16 complete revolve turn around time gas spring 17 just in the second half district, start in other words to cushion after piston 17 moves in the cylinder of gas spring 17 completely.In other words, if use this buffering, by shown terminal location, the rotation of the entrance blocking device be connected with driven wheel 13 is until the carrying out do not cushioned before terminating of the rotation of half.But buffering works with piston 18 with shifting out velocity correlation, thus due to discontinuous motion, the kinematic design cushioned based on discontinuous transmission device rotates halfth district until work to whole system more and more close to the terminal rotated from second, enough strong buffering is there is thus, to prevent entrance blocking device from occurring swing and make it can stop in the region of its terminal location in land.
Fig. 3 shows according to ideal curve 51, according to the curve 50 of the solution of prior art and the figure line according to curve of the present invention, depicts the curve of piston speed about the anglec of rotation of the gear 12 of outlet side in the figure.Consider the symmetry of two gears 11,12, curve 50,51 and 52 is symmetrical curves, forms the point symmetry around zero point when its symmetry is formed in rotation π.Ideal curve 51 illustrates in the region near symmetric points 53 slope with steeper also substantial constant, this means to cushion uniformly in this region.At symmetric points 53 place, system reaches unstable balance, and under this equilibrium state, piston speed has flex point.By high velocity variations avoid entrance blocking device therebetween position due to the reason of friction may be stuck.Same situation is also applicable to the curve 52 utilizing gear according to the present invention to realize.The curve utilizing identical gear to realize of reflection prior art is only had to have piston speed change too small on slope, this means temporary transient deceleration and acceleration, this deceleration and the centre position buffering accelerated because the damping characteristics of piston 18 causes at the volley.When utilize gear of the present invention to realize curve 52, buffering or the height of piston speed are put also Billy and are offset towards the direction of terminal location further with the curve 50 that identical gear realizes, and this can cause terminal location operation more clearly.
Transmission device is promoted if not the people by entrance blocking device, and the motor being mounted in outlet side drives it, then transmission device according to the present invention is guaranteed 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 side.In other words, this design makes it possible to be used for by identical transmission device manually running and motor-driven operation, wherein when motor-driven operation, complicated control method need not be implemented to motor, but it can be made to run under constant rotating speed, to guarantee the suitable motion of entrance blocking device, namely realize Accelerating running and running slowly clearly.
According to the arrangement of Fig. 5, buffer 10 is shown, the driving shaft 13 of this buffer is connected with turnsile 20 by speed changer 21.This turnsile 20 can use together with identical buffer 10, identical with revolving door or similar devices.Here only need to arrange another bent axle element 14 or select another eccentricity when using crankshaft disk, to pay attention to the larger quality of revolving door when cushioning.Due to the shown calibration of 120 °, have selected the gearratio of 1:3 here.If the turnsile 20 with 2 or 4 locking fences such as should be adopted, then only need to make gearratio suitable therewith, namely adopt the gearratio of 1:2 when two deciles, adopt the gearratio of 1:4 when the quartering.When selecting the gearratio of 1:3, when turnsile 20 rotates a complete circle, driving shaft 16 rotates three times, namely crosses buffering maximum point three times, namely each by crossing buffering maximum point during turnsile 20.
According to the view of Fig. 6, also set and the present invention is used for double-open swinging door 30.In the region of the wall of double-open swinging door 30 outside, be provided with rack rails 31, rack rails is directly engaged in driven wheel 13 and is also placed on rotation thus.The size of driven wheel 13 is selected in this case like this, that is, open completely and rotate a complete circle corresponding to driven wheel 13.In other words, double-open swinging door 30 first swing open, now driven wheel 13 rotates a complete circle.In the region of terminal location, also buffering is set along contrary direction.Be noted herein that the buffering in order to realize ideal, not carry out the rotation of whole circle, be therefore similar to the rotation achieved from buffering maximum point to buffering maximum point.When moving back and forth, this always shows impracticable, but is not then this situation in two-way use turnsile 20.Now do not need to take closing organ with certain making every effort to overcome yet, but only run, such as to allow the automatic clamping of Lock pawl at terminal location.
Finally, Fig. 7 illustrates another embodiment, wherein achieves sliding door 40.According to foregoing content, the tooth bar 41 being parallel to wall installation is here engaged to and arranges in the transmission device of driven wheel 13, thus also realizes buffering by buffer 10 when sliding door 40 is opened completely here.Therefore cushion here and also carry out like this, make sliding door arrive its terminal location under buffering.
