Description
The present invention feeds the method for accepting on the conveyer to the cotton open width of lean ore uncured, the cementing agent dipping about a kind of, and the equipment of implementing this method.
When making mineral wool paper, key is will obtain the product of even as far as possible and homogeneous to obtain higher insulating capacity.And it should have elasticity as far as possible when lower density, require fiber mainly to stretch in paper plane.Owing to exist elasticity, paper can be compressed to pack and to transport.
In order to reach this purpose, be right after after carrying out fiber separation and collecting a basic weight on the collecting conveyor in 110 to 450 gram/sq ms, the thin open width in the scope of 100 to 200 gram/sq ms preferably.Open width is thin more, and the quality of finished product is good more.In order when production approaches open width capacity rating to be remained on desirable level, the speed of the speed of open width and its conveyer must be very high.Under the normal circumstances, the speed of open width surpasses 100 meters/minute, yet only in the scope of 100 to 200 gram/sq ms, this just needs higher speed so that capacity rating is remained on the desirable level to the basic weight of open width.
The various methods that fold the mineral wool width of cloth are disclosed in and include US Patent specification 2450916(1948) and the british patent specification 772628 medium patents of evening when a little in.These methods all are to finish the method for the open width that folds with the pendulum-type conveyer.
When using the pendulum-type conveyer to export open width, importantly the peripheral velocity of mouth will be substantially equal to the speed of open width, folds in output procedure or elongates to prevent open width.
Up to now, pendulum-type mechanism generally includes an action, and in this action, two end positions of pendulum-type conveyer are apart from accepting on the conveyer vertex farthest, and the lower dead point of pendulum is on the most approaching nadir of accepting conveyer.In order to make thin open width obtain required high productivity, just should improve the output speed of pendulum-type conveyer.Yet this is impracticable in known device.In fact, the known high speed pendulum-type conveyer that is used for feeding light open width and has a high wobble frequency will be directed at the inaccurate placement of open width.Like this by a connecting rod with know method driven and give speed of mouth of conveyer around the pendulum-type conveyer of a fixing suspension center swing, this speed is maximum when pendulum is in middle position, and by sinusoidal rule reduction, be reduced to zero during to end position, produce acceleration/accel by sinusoidal rule again at end position.The extreme lower position of the mouth of this pendulum-type conveyer must be arranged in the top of accepting conveyer, distance is about 0.2 times the place (exporting width under normal circumstances is 2 meters) of export width, accepts on the conveyer and can not be stretched so that allow open width be placed on uniform level.Because the nadir of pendulum and the distance of accepting between the conveyer reach more than 40 centimetres even 40 centimetres, feed the open width that and to have irregular edge.Output speed approximately is 130 meters/timesharing, the degree of irregularity of the secondary width of cloth of formation will be approximately output width ± 5%.This means that in order to obtain the mineral wool width of cloth in working order of required width, the secondary width of cloth must be given the corresponding width of some greatly, because that part of material that does not meet the requirements will be cut.This means that material has huge loss.
Output open width is known with the pendulum-type output mechanism of the operation of implementing to fold continuously on constant altitude directly over the support.Be provided with a hinge means and be used for the mouth of swinging mechanism is maintained on the constant height accepting the conveyer top, move back and forth and then realize by chain/connecting rod mechanism.The velocity curve of hunting motion is Duan Youyi constant rate period therein, at its each end position deceleration and acceleration phase by sinusoidal rule is arranged then.Pendulum must slow down on two end positions and quicken soon, and the motion that makes pendulum is as far as possible corresponding to the open width output of in unit time, and this just causes huge strain in physical construction.Therefore, this mechanism only is suitable for using being lower than under about 100 meters/minute output speed.
Another shortcoming with swinging mechanism of high hunting frequency is that the quick crank motion with the swinging mechanism on big surface can produce strong air-flow.Air-flow has hindered thin open width to place on bed surface.
Thisly be used for thin open width fed that to accept on the conveyer the swinging mechanism of alternating layer be known.Yet they all have appreciiable shortcoming; The edge is irregular, causes the huge loss of material; Speed is too low can not to satisfy required capacity rating; Powerful deceleration and acceleration force cause mechanical strees huge in the structure; The problem of air-flow hinders the placement of open width.
The objective of the invention is to reduce or eliminate fully these shortcomings, particularly to obtain a kind of the have correct placement of flat edges and the web of height homogeneous, reaching of this purpose is that mouth by the pendulum-type conveyer is endowed a kinematic velocity, this speed is at least 30% of swing, not exceed in 60% the scope be constant and equal or approach the output speed of open width, the remainder of doing in swing then is made of an in check action that has deceleration and quicken, and the mouth of pendulum-type conveyer rises and partly descends at the corresponding basically acceleration phase of backhaul in the part in decelerating phase at least.This purpose also reaches by the pendulum-type conveyer with following feature.This pendulum-type conveyer is characterised in that the distance between the two-wheeled and the diameter of wheel are configured to like this, make the traverse of link end when chain drive-belt moves, account at least 30% of pendulum stroke in two horizontal components, do not exceed 60%, and the traverse of link end accounts for the part of the remainder of pendulum stroke when the exterior portion of two-wheeled circumference is moved at chain drive-belt, at this, the pendulum-type conveyer this at least 30%, do not exceed in 60% the pendulum stroke and be endowed constant speed, and in the part of the remainder of stroke, before the end position of pendulum stroke, be endowed controlled deceleration, be endowed controlled acceleration in the rightabout same big basically pendulum stroke part behind this end position, its feature also is to be provided with device, this device provides a upward movement for the mouth of pendulum-type conveyer at least one pendulum stroke part before end position, and provides a descending motion in the same big basically pendulum stroke part behind end position.
Used a kind of known actuating device in a preferred embodiment of the invention, give in the stage casing of pendulum stroke that the pendulum-type conveyer of swing-hereinafter referred to as-one constant motion of pendulum, the part beyond the constant speed part is then given a corresponding deceleration and an accelerated movement by sinusoidal rule.Part with constant speed can be 30 to 60% of a whole pendulum stroke.Be equal to or almost completely equal the output speed of open width in the constant speed of the pendulum of middle section.This makes pendulum can be more close accept the surface, be provided with in half the place that is approximately distance that conventional crank-driven allows, thereby guaranteeing that open width is positioned over much betterly and is fixed on accepts on the conveyer.
When putting when doing hunting motion, in the zone beyond the constant speed part, pendulum slows down by controlled sinusoidal rule or the speed of acceleration drives.At least at the deceleration of stroke or accelerating part, promptly before constant speed part back, the mouth of pendulum is configured to rise or descend.Because the height of pendulum end is slowing down or acceleration mode changes, potential energy is correspondingly stored or emits by pendulum, and the result is to be little at the stress in this mechanism than the machinery that the mouth of those its conveyers moves along horizontal route in whole swing total length.
By the centre portion with constant speed and two pendulum strokes that the edge portion branch that has deceleration and quicken constitutes, be suitably by one for no reason driving chain operate in two coplanar, separate on the sprocket wheel of setting and produce mutually, at this, there is a connecting rod connecting pendulum and the support on driving chain.The width between centers of two sprocket wheels is corresponding to the part with constant speed of pendulum stroke, and a semicircumference of each wheel is corresponding to the part of slowing down and quickening that has of pendulum stroke.
By the pendulum stroke that the centre portion with constant speed and two edge portion branch that have deceleration and quicken constitute, also available what is called " Fu Gesheng " (Ferguson) mechanism produces, and rotation wherein drives and produced by elliptic gear.
The mouth of pendulum can be guided to move along difform path in the distance of hunting motion.Simple embodiment is an arc running route, puts therein around a fixing hitch point swing.In such an embodiment, pendulum is with the split hair caccuracy operation, and its output speed is approximately 200 meters/minute.This is because the mouth of pendulum can be swung near accepting conveyer very much, and at the most approaching driving device of accepting of the mid point of whole swing, the open width of therefore being fed out can be fixed on following hello the mineral wool width of cloth that goes out immediately, thereby the air-flow that caused by hunting motion influences.On the end position of pendulum stroke, the mouth of pendulum has risen and has exported about 0.1 times of width, is about 20 centimetres when the output width is 200 centimetres promptly, and the result is that the position of edging is more accurate, and this is because the Zhe circle of the mineral wool width of cloth is less.Another advantage of this embodiment be the pendulum can make shorter, be about output width 0.7 to 1.0, promptly about 140 to 200 centimetres, this causes actuating device that lower maskant moment of inertia and less stress are arranged.Use short pendulum, interference in air flow has also reduced.
In this embodiment, pendulum can be adjusted to the closest point of approach that makes it accept conveyer above only leave 5 to 10 centimetres, so almost be fixed in the middle section of running route feeding the web that immediately.This causes the mineral wool width of cloth to have in good order edge.In about 50% scope of 200 centimetres output width is constant speed, and putting on stroke most is output width 80%, pendulum length be about the output width 75%, promptly 150 centimetres, pendulum rising on end position is about 12%, promptly 24 centimetres.
In another preferred embodiment of the present invention, make pendulum and its mouth in the middle section of pendulum stroke, accepting conveyer above a constant height level move, and on outermost position, rise to surpass this height.
Upward movement can begin on mid point any point later of hunting motion, but when beginning, begins in the decelerating phase of hunting motion at the latest, this just allows to feed the open width that with constant speed from the mouth of pendulum has enough spaces to gather loop to open width below mouth, and mouth then moves with the speed that is lower than the open width output speed.Upward movement is beginning behind the pendulum midstroke the most for a long time, pendulum and its mouth just mark a continuous arc line, or a bit beginning before the end position of pendulum stroke, will be formed with enough spaces at the face of accommodating that rises and allow and gather loop and under control, settle and in return motion, form neat limit.
The path that mouth marked of pendulum can be the various combinations of the line, round wire, gradual change camber line or these lines that rise linearly.
By various guiding devices, make pendulum or its mouth be forced to depart from the natural pendular motion that it has circular outgoing route.From departing from nature pendular motion that time, but the hitch point of pendulum just must be that pendulum radius vertical ground motion or mouth is variable.
Wishing to have one, to include one mainly be the middle body of level and the output running route of curved end part, the support arm that is contained on the bearing of pendulum can for example include a lower end, and this lower ending pivot is contained on the bearing of pendulum outside to force pendulum to move along a substantially horizontal path.The motion this part in, the hitch point decline/rising of pendulum.Hitch point is arranged to like this, makes it will change the rising path over to and run into a backstop in backhaul changes descent path over to same area position or be blocked from horizontal route in the outermost regions of pendulum stroke at pendulum.The installation of support arm on the bearing of pendulum is configured to like this, make pendulum can be in the case, for example by fork bearing with respect to an arm swing.A spring suitably can be arranged between the support arm of the link end of pendulum and the height and position that guiding is put, acceleration and deceleration force are partly balanced on the end position of pendulum.
The motion of pendulum also can be guided by for example fixing guiding device that is provided with symmetrically with respect to the central axis of pendulum, and wheel or a slide mass on bearing that is contained in pendulum are provided to move along this guiding device.The running route of mouth will be with the shape unanimity of guiding device.The height of guide rail above mouth is decided by the optimization of geometric relationship and force of inertia.
The hitch point of pendulum also can be fixed, but mouth just need be radially movable with respect to hitch point.
The present invention general is described in detail in conjunction with the accompanying drawings in the mode of embodiment below, wherein:
Fig. 1 schematically shows the action of two preferred embodiments (A) and pendulum (B); Embodiment (A) shows a kind of swing of pendulum, and constant speed then was to slow down and acceleration before this, returned constant speed, repeated down like this, and Bai mouth marks a circular arc path simultaneously, and hitch point P
ABe fixed; Embodiment (B) shows the swing of another kind of pendulum, constant speed before this, then be to slow down and acceleration, return constant speed, repeat down like this, the mouth of pendulum moves on a constant altitude above constant rate period is being accepted conveyer, slow down and acceleration phase then along an arc-shaped path of movement, hitch point P
BBe movable.
Fig. 2 illustrates a preferred embodiment of pendulum, comprises related actuating device, and pendulum is illustrated on three different positions,
Fig. 3 illustrates another preferred embodiment of pendulum, comprises related actuating device, and pendulum is illustrated on three different positions.
In Fig. 1, the right side of figure illustrates situation (A), and all around a P swing, some P fixes in this situation pendulum wherein at constant rate period and deceleration and acceleration phase, and standardized circular arc of mouth.Pendulum is driven by the chain of constant speed by guiding device D.Connecting rod V is pivotally attached on the support T that moves along driving chain, and is pivotally attached to the K of swinging mechanism
AThe point on.On driving chain, marked 1 to 12 each point, wherein, the middle position of point 1 and 7 expression pendulum, the end position of point 4 and 10 expression pendulum, point 12 and 2 and the limit of putting 6 and 8 expression constant speed region.As the fulcrum T of connecting rod during in position 1, swinging hanging on hitch point P, the position 1(A of mouth) expression.From putting 1 to putting 2 pendulum with constant motion, because hitch point P fixes, mouth marks a circular arc.From put 2 to point 4 pendulum with decelerated movement, change sense of motions at point 4, quicken to point 6 from putting 4, mouth marks the circular arc that rises and descend along with again earlier, from put 6 to point 7 speed be constant, mouth marks a circular arc.Use 7(A among point 7 the embodiment (A) at Fig. 1) expression.Depend on attachment point K
AIn the position of laying out with respect to actuating device D, can produce geometric asymmetry more or less, promptly put 3 with point 5 with put 2 and 6 all depart from each other with point, this shows in the diagram.Pendulum rises about 24 centimetres at end position 4, and this also is illustrated among the figure that draws in 1: 10 ratio, and a controlled open width loop is formed on the point of transition.Because mouth is to accepting conveyer S
AThe less and output speed of distance synchronous with the swing speed of mouth, feed the open width that and just be fixed on the bed surface soon, this is also shown in the scheme drawing.Get back to a little 1 swing and do through putting 12 from putting 7, on the chain drive be the inverted image of point 1 to the motion between the point 7, thereby no longer narration.
The left side of Fig. 1 illustrates situation (B), and the mouth of pendulum is wherein being accepted conveyer S at constant rate period
BThe constant altitude motion is pressed in the top, then moves along circular path in deceleration and accelerated movement stage.At the middle position point 7 of pendulum, the hitch point of pendulum is at P ', but just drops to a P when moving to a little 8, so mouth moves along horizon.From putting 8 by putting for 9 to point decelerating phase of 10 and from putting 10 by the acceleration phases of point 11 to point 12, it is motionless that hitch point P is maintained fixed, mouth marks a circular arc.As shown in the figure, accept conveyer S
BBe in than on the higher position of situation (A), because the hitch point of pendulum is placed higherly on middle position in situation (B).
Pendulum rises about 16 centimetres at its end position, and this as seen from the figure.Loop also is being well controlled in this situation, this be because open width is short to the distance of bed surface, particularly in 7-8 and these two sections strokes of 12-1, and since in these trip segment output speed synchronous with the swing speed of mouth.
For the mouth that makes pendulum in main portion-shown in each situation in be the 50%-along continuous straight runs motion of pendulum stroke, hitch point must move to P from P ' therein, this just need take special measure.Two preferred embodiments of this structure are illustrated in Fig. 2 and 3.
Fig. 2 and 3 illustrates the related driver train of pendulum partial sum of the machine that is used for producing the mineral wool width of cloth.The conveyer label of feeding of open width is 1, and it is that 2, two relative conveyer labels are 2a and 2b that the device label is sent in related swing, and the deflector roll label of mouth is 3a and 3b.Accepting the conveyer label is 4, and the driver train label is 5, and two wheel labels of driver train are 5a and 5b, and the connecting rod label is 6.Part 1 to 6 is corresponding mutually in Fig. 2 and 3, thereby with same label.
In Fig. 2, the wheel label that swing do is imported in the guiding device is 7, and being fixed on swing, to send the axle label of the wheel on the device be 7a.Wheel 7 moves thereon and determines that the label of guiding device of the running route of mouth is 9.It is 10 that the mouth label of device is sent in swing.
When producing the mineral wool width of cloth, open width is fed and is further moved enter swinging mechanism 2 between conveyer 2a and 2b from its conveyer 1 of feeding, and feeds in mouth 10.Pendulum swings back and forth when open width feeds between deflector roll 3a and 3b.When the distance b of connecting rod between the center of drive wheel 5a and 5b
1In when motion, wheel 7 has constant speed and the flat of guiding device 9 of correspondingly passing by, thereby makes deflector roll 3a and 3b walk a segment distance B on a constant altitude of accepting above the conveyer
1When connecting rod along equaling distance b
2The peripheric movement of drive wheel the time, the pass by curved up end of guiding device 9 of wheel 7, therefore the mouth of pendulum is at distance B
2On mark corresponding curved path.The position of guiding device 9 is decided by required geometry of motion.The hitch point 22 of pendulum can move along the line of centers of pendulum stroke, and the conveyer 1 usefulness hinge of accepting of open width is contained on the bearing so that can follow the motion of the input end of pendulum in vertical direction.
Fig. 3 illustrates another preferred embodiment of pendulum of the present invention.The lower ending pivot of support arm 20 is connected in the supporting on the pendulum line of centers outside, in hunting motion, and the upper end of support arm 20 installs on the supporting-point 8 of the connecting rod of laying out 6 by fork bearing.Supporting-point 8 is arranged to can motion in the fork 21 of the upper end of support arm.The hitch point 22 of pendulum can vertically move along the line of centers of swing, and the conveyer 1 usefulness hinge of feeding of open width is contained on the bearing so that can follow the motion of pendulum in vertical direction, and it is identical to catch up with the situation of stating.When connecting rod was passed by horizontal zone between two drive wheels, pendulum was drawn to the position of a band angle, and hitch point moves downward, until corresponding site till the constant rate period distal point is run into a backstop 23.Backstop prevents further displacement downwards of hitch point, and pendulum is forced to around the hitch point P swing of now having fixed.In this deceleration part of motion, supporting-point 8 moves up in fork 21, thereby does not hinder pendulum to rise along a camber line.Be flapped toward lower swing in acceleration phase subsequently, mouth 10 marks same camber line, and supporting-point 8 moves towards the bottom of fork 21 simultaneously.Same motion repeats in opposite direction.
Be preferably in deceleration and the acceleration force by the swing generation of putting of a spring with absorption portion is set between central axis and the support arm 20.
Fig. 2 and 3 embodiment illustrate a kind of like this action of pendulum separately, and output movement its level or substantially horizontal is consistent with constant rate period, and dipping and heaving with corresponding slow down or acceleration phase consistent.The controlled moving line that departs from curved line of mouth certainly is conditioned, and making it can be at constant rate period b
1Or subtract or acceleration phase b
2Any point on begin.
As mentioned above, deceleration and acceleration force partly are owing in the upward movement of exporting both sides, partly be because the less pendulum with less quality all less than previous used method.
Clearly, the one skilled in the art can rise motion of the present invention, pendulum at two limit positions, have the notion of constant speed in the intermediary of the swing of pendulum, is implemented among the embodiment beyond the foregoing description with different ways.
