Definitions

  • the present invention relates to a process for feeding a thin binder impregnated uncured mineral wool web on a receiving con ⁇ veyor and to a device for carrying out the process according to the preamble of claims 1 and 9.
  • 2 weight varies in the range of 110 to 450 g/m , preferably 100 to 200 g/m is collected on a collecting conveyor immediately after the defibration.
  • the spe of the primary web as well as that of its conveying devices has be high.
  • the speed of the primary web is over 100 m/mi however, the basis weight of the primary web being only in the
  • the pendulum mechanism usually has comprised an ope ⁇ ration, in which the extreme positions have been highest above the receiving conveyor, and the lower dead point of the pendulum has been closest to the receiving conveyor.
  • the out ⁇ put rate of the pendulum conveyors should increase, however this is not feasible with known devices.
  • a high speed pendu ⁇ lum conveyor that feeds out a light web and has a high pendulum frequency yields an inexact laying of the primary web.
  • a pendulum conveyor driven in a known manner by a connecting rod and oscil ⁇ lating along a circular arc imparts a speed to the output end of the conveyor that is maximal when the pendulum is in the central position and decreases sinusoidally to zero in the extreme posi ⁇ tion, from where a sinusoidal acceleration reoccurs.
  • the output end of such a pendulum conveyor must, in its lowest position, be disposed c. 0,2 times the output width, which normally is 2 , above the fed out wool web, in order to allow the primary web to be deposited in an uniform layer on the receiving conveyor withou being stretched.
  • the distance between the pendulum and the receiv ing conveyor being that long up to 40 cm and more, the fed out web will get uneven edges.
  • the output rate being c.
  • the irregularities of the secondary web formed will be c. +/- 5% of the output width. This signifies that the secondary web must b imparted a correspondingly larger width in order to achieve a faultless web of the desired width, since the undesired material has to be cut off. This means a great loss of material .
  • Pendulum output mechanisms in which the folding process is car ⁇ ried out by continuously feeding out the primary web at a constan height above the support, at a constant height, are also known.
  • a articulation system for maintaining the output end of the pendul mechanism at a constant height above the receiving conveyor is provided, and the to and fro motion is obtained by a chain/con ⁇ necting rod-mechanism.
  • the speed profile of the oscillating moti has a constant speed period in the middle and a sinoidal retarda tion and acceleration phase in each end position.
  • the pendulum must be rapidly retarded and accelerated in the end positions fo the pendulum motion to correspond to the output amount of the primary web per unit of time, causing great strains in the mecha ical constructions. Consequently, the mechanism is appropriate only at output rates below c. 100 m/min.
  • Another drawback of pendulum mechanisms aving a high pendulum frequency is constituted of the strong flows of air generated by the rapid back and fro motion of a pendulum mechanism having large surface. The air flows hamper the depositing of the thin primary web onto the bed.
  • the purpose of the present invention is to reduce or totally eliminate these drawbacks, and especially to obtain an exact out laying with even edges and a web with high homogeneity, and this has been achieved by providing a method and a device, of which t main characteristics are presented in claims 1 and 9.
  • a prior known drive system is used, imparting to the oscillating pendulum conveyor, called pendulum from now on, a constant rate of motion in the middle of the pendulum motion and a sinusoidally decreasing respectively increasing speed in the extreme positions of the pendulum motion.
  • the period having constant speed may be in the range of 30 to 60% of the entire pendulum swing.
  • the constant speed of the pendulum in the central area equals totally or nearly totally the output rate of the primary web. This enab ⁇ les the pendulum to be disposed closer to the receiving surface, at about half of the distance allowed by conventional crank drive thus ensuring considerably better the deposit and the fixation of the primary web on the receiving conveyor.
  • the pendulum In areas outside the phase having a constant speed the pendulum is driven at a sinusoidal ly decreasing respectively increasing ra te, while the pendulum pursues its pendulum motion. At least during part of the motion at a decreasing respectively increa ⁇ sing rate in the extreme positions of the pendulum swing, the output end of the pendulum is arranged to rise in the final phase of the pendulum motion and to sink in the initial phase. Due to the changing of the height of the pendulum in the retardation re spectively the acceleration phase, potential energy is stocked respectively discharged, resulting in less stress forces on the mechanism than those generated when the output end of the pendulu describes a horizontal path over the entire pendulum swing.
  • the pendulum motion consisting of a central portion having a constant speed and two extreme portions having retarding and ac ⁇ celerating speeds, is appropriately produced by means of an end ⁇ less drive chain running over two coplanar interspaced chain wheels, whereby a connecting rod connects the pendulum with a carrier on the drive chain.
  • the centre distance of the chain wheels corresponds to the portion of the pendulum motion having a constant speed and half the circumference of each wheel corres ⁇ ponds to the pendulum motion having retarding and accelerating speed.
  • the pendulum motion consisting of a central portion having constant speed and two extreme portions having retarding and accelerating speed may also be produced by means of a so- called Ferguson gear, in which the rotary motion is transmitted by elliptical gear wheels.
  • the output end of the pondulum may be guided to move along diffe rently shaped paths in the course of the pendulum motion.
  • the mo simple embodiment is an arched trajectory, whereby the pendulum swings around a stationary point of bearing.
  • the pendulum operates with great accuracy at output rates c. 200 m/min. This is allowed by the fact that the output end of the pendulum may strike very close to the receiving conveyor, an closest thereto at the midpoint of the total swing, whereby the fed out primary web may be immediately fixed into the underlying fed out wool web and thus remains undisturbed by the air flows caused by the pendulum motion. In the extreme positions of the pendulum motion the lower end of the pendulum rises c.
  • the pendulum may be relatively short, c. 0.7 to 1.0 times the output width, i.e. c. 140 to 200 cm, which results in lower mass-moments of inertia and smaller stresses in the driving device.
  • the air flow disturbances are also reduced b a shorter pendulum.
  • the pendulum may be adjusted to strike at its closest point only 5 to 10 cm above the receiving conveyor and thus to fix almost immediately the fed out web into the central area of the trajectory. This results in a wool web havin very even edges.
  • the pendulum rises c. 12%, i.e. 24 cm, in the extreme positions.
  • Another preferred embodiment of the invention is the one in which the pendulum and its output end are made to move horizontally at a constant height above the receiving conveyor in the central zo ⁇ ne of the pendulum swing and to rise above this in the outmost positions.
  • the rising motion may be started at any point after the mid point of the pendulum motion, but at the latest during the retardation phase of the pendulum motion, thus allowing for the primary web, which is fed out from the output end of the pendulum at a constan rate, enough space below the output end which then moves at a low er rate than the output rate of the primary web.
  • the rising mo ⁇ tion thus starts at the earliest immediately after the mid point of the pendulum motion, the pendulum and its output end then describing a continuous arched line, or at the latest at such a point before the extreme position of the pendulum swing, that enough space is allowed to be formed below the rising pendulum fo the accumulating loop to settle under control and to form an even edge during the reverse motion.
  • the path described by the output end may be a linearly rising, circular, progressively arched line or various combinations of these .
  • the pendulum or its output end is forced to deviate from the natural pendulum motion having a circular output path. From the moment there is a deviation from the natural pendulum motion, the oscillating point of the pendulu must be vertically movable or the swinging radius of the output end be variable.
  • an arm mounted bearings in the pendulum may for instance comprise a lower end that is pivotally mounted on bearings outside the pendulum, thus forcing the pendulum to describe an essentially horizontal path.
  • the oscillating point of the pen ⁇ dulum sinks/rises.
  • the oscillating point has been disposed so as to reach a stop or else stop in the position in which the pen dulum is to pass into a rising motion in the outmost zone of the pendulum swing respectively sinking motion in the same zone duri the reverse motion.
  • the mounting of the arm on bearings in the pendulum is disposed so as to enable the pendulum to oscillate with regard to the arm at this stage, e.g. be means of fork bear ings.
  • a spring may appropriately be disposed between the connec ⁇ ting rod top of the pendulum and the arm guiding the height posi tion of the pendulum, whereby the acceleration and retardation forces are partly equilibrated in the extreme positions of the pendul urn.
  • the motion of the pendulum may also be guided by for instance a fixed guide disposed symmetrically with regard to the central axis along which a wheel mounted on bearings in the pendulum or sliding body are disposed to move.
  • the trajectory of the output end will then correspond to the shape of the guide.
  • the height o the guide above the ouptut end is determined by the optimization of geometry and mass forces.
  • the oscillating point of the pendulum may alternatively be sta ⁇ tionary while the output end is radially movable in relation to the oscillating point.
  • figure 1 presents a schematical representation of the pendulum motion of two preferred embodiments; the motion of the pendulum at a constant speed and subsequently at a retarded and an accele ⁇ rated speed, while the output end of the pendulum describes a cir cular path (case A) respectively the motion of the pendulum at a constant speed and subsequently at a retarded and an accelerated speed while the output end during the constant speed phase moves at a constant height above the receiving conveyor and during the retardation respectively acceleration phase moves along an arched path (case B) ,

Abstract

Le procédé décrit sert à acheminer une bande primaire de laine minérale sur un transporteur de réception. A cet effet, on utilise un transporteur à pendule. Afin d'obtenir une bonne qualité ainsi que l'aptitude désirée, la bande primaire doit être fine et la vitesse de sortie élevée, ce qui occasionne des problèmes de fixation de la bande primaire dans la bande déjà acheminée et de bouclage des bords de la bande acheminée. Selon la présente invention, on résout ces problèmes en choisissant la trajectoire et la vitesse de déplacement de l'extrémité de sortie (10) du transporteur de réception (2) de sorte que ladite trajectoire comprenne une partie centrale (B1) ayant une vitesse constante, qui est égale ou qui est presque égale à la vitesse de sortie de la bande primaire, et une partie extrême (B2) ayant une vitesse de freinage ou d'accélération, respectivement. De cette façon, l'extrémité de sortie peut se déplacer près du transporteur de réception et être rapidement fixée dans le lit, pendant que le pendule permet la création d'un espace approprié dans les positions extrêmes pour la boucle de bord, laquelle est également rapidement fixée dans le lit et forme un bord uniforme. La présente invention se rapporte également à un dispositif de mise en oeuvre dudit procédé.
