Definitions

  • the invention relates to techniques for packaging products such as mineral wool felts. These low density products, due to their resilience, are advantageously compressed during storage and transport.
  • a traditional conditioning consists in rolling up the felt on itself by compressing it. Cylindrical rollers are thus formed, the stability of which is ensured by the packaging usually consisting of a sheet of paper or of a polymer material.
  • the compression ratio chosen must also take into account the thickness recovery capacity of the product during its implementation.
  • the qualities of the felts, in particular the insulating qualities, are in fact a function of their thickness. Experience shows that to ensure a satisfactory thickness recovery when the product ceases to be compressed, it is necessary to limit the compression rates imposed.
  • the best possible winding for these products is that which, by ensuring uniform compression over the entire length, allows to operate at the highest admissible rate without compromising the quality of the product. It is also the winding which guarantees the quality of the product in a packaging offering the minimum size.
  • the felt is led into a space delimited by two conveyor belts and a compression roller. These mats and this roller drive the felt in a rotational movement leading to its winding on itself.
  • the compression roller can move so as to gradually increase the space in which the felt is wound.
  • the increase in the pressure exerted results directly from the increase in the “diameter of the wound felt.
  • the compression roller is arranged at the end of a movable arm.
  • the crescent felt roller repels the compression roller.
  • a pneumatic cylinder fixed on the arm carrying the compression roller exerts a reaction which tends to oppose the movement of the arm.
  • the pressure in the pneumatic cylinder which is transmitted via the arm and the compression roller to the felt during winding is all the greater the greater the displacement of the compression roller.
  • the invention proposes to provide means for ensuring a more uniform product winding over their entire length.
  • the invention also proposes to provide means conveniently adaptable to the treatment of various products.
  • a device is used such that the compression exerted on the felt does not result from a passive reaction, but on the contrary, from a movement of the compression members according to a program well determined by l 'operator.
  • the compression members are associated with motor means capable of ensuring a modification of their relative arrangement so that at any time, during the winding of the felt, the space left available between these members determines for each turn a well-defined compressed thickness, depending on the length of the felt already wound up.
  • the motor means ensuring the movement of the compression members are controlled by control means associated with measurement means and calculation means. This movement takes place according to a predetermined program.
  • the calculation means establish the operating instructions of the driving means as a function of various variable parameters of the installation. One or more of these parameters are measured directly by appropriate means during operation, and are transmitted for processing to the calculation means. Other variable instructions can also be entered by the operator.
  • the invention relates to a device for forming rollers from strips of compressible material comprising a set of at least three members delimiting a space in which the winding takes place, these members being animated so that in contact with them the strip is wound on itself in the space which they delimit, at least one of these members being movable relative to the others during operation, these members being respectively a first conveyor on which the belt is transported to this space, a second conveyor arranged at the end of the first and making an acute angle with the first and a compression roller, the compression roller being located in the angle of the conveyors (see US-A-3,991,538), characterized in that the compression roller is moved by motor means such as a hydraulic cylinder or the like directed by means of control means by calculation means which operate s According to a program in memory and from the measurements transmitted by sensors according to the course of the formation of the roller and a position encoder transmitting a signal corresponding to the position of the compression roller.
  • motor means such as a hydraulic cylinder or the like directed by means of control means by calculation means
  • the winder shown in Figure 1 can be used for the formation of rolls of glass wool felts or similar compressible products.
  • This reel can be placed directly at the end of a production line for these felts.
  • the manner in which the fibers are produced is immaterial to the invention. It suffices, in particular after the polymerization step of the binder which makes the fibers adhere to each other, that the felt thus formed has good resilience, in other words that it can undergo significant compression and then resume most of its initial thickness when it ceases to be compressed.
  • the felt 1 progresses on the conveyor 2 in the direction indicated by the arrow.
  • the conveyor 2 is set in motion by the motor 3 by means of a belt 4 and the drive drum 5.
  • the arm 7 carries a conveyor 11 whose end furthest from the axis 9 is located opposite the end of the conveyor 2 at a short distance from the latter. This distance is as short as possible. Its purpose is to facilitate the initiation of the winding by leaving the felt a minimum of space. This distance must however be sufficient to avoid any risk of friction of the conveyors on one another.
  • the conveyor 11 is inside an envelope which is only partially shown in the figure for reasons of clarity.
  • the limit of the missing part of the envelope is indicated in dotted lines.
  • the faces of the conveyors form an angle of less than 90 ° between them.
  • This angle is advantageously between 40 and 80 ° and preferably close to 60 °.
  • the conveyor 11 is set in motion by the motor 3, by means of a deformable articulated transmission not shown.
  • This articulated transmission is such that it allows the tilting of the arm 7 in the manner described below.
  • a jack 13 fixed on a support 33 integral with the chassis 6 makes it possible to tilt the arm 7 so as to separate the end of the conveyor 11 from that of the conveyor 2. In the separated position, the distance separating the two conveyors is greater than the diameter of the felt rollers formed to allow the evacuation of the latter.
  • the power supply and the control of the jack 13 are not shown.
  • the arm 8 comprises two identical parts located on either side of the arm 7 which they frame.
  • the lower ends of the two parts of the arm 8 carry two rollers 14 and 15. These rollers are rotated by means of chains, not shown, located along the arm itself.
  • the drive is provided by the motor 3.
  • the return wheels of the movement of the chains are coaxial with the axis of rotation 10 of the arm 8, so that a movement of the arm 8 can be done without modifying the tension of the chains .
  • a variable speed drive is interposed on the transmission system.
  • the arm 8 is extended by a counterweight 17 which balances it and makes its movement easier.
  • the space in which the felt strip is wound up is delimited by two conveyors and a roller. If necessary, at least one of the conveyors could be replaced by a roller fulfilling the same function. Despite a slightly more complicated mechanism, the use of conveyors is advantageous for several reasons.
  • a first reason is due to the fact that even if the rollers are of relatively large dimensions, the contact with the wound strip takes place on a convex surface which tends to deform the felt more than does a conveyor which has a flat surface. This is important for proper roll formation.
  • the third support point on the compression roller also moves in a movement which maintains this good arrangement.
  • the support points are equidistant from each other.
  • the distance from the compression roller to the axis of rotation is sufficiently large and the position of this axis is preferably such that the displacement takes place substantially along the bisector of the angle of the two conveyors.
  • a pneumatic cylinder 18 mounted on a support 19 secured to the chassis 6 makes it possible to move the arm 8 through its rod 20.
  • the pneumatic cylinder intervenes purely passively.
  • the arm 8 pushed back by the wound felt 21, pivots about the axis 10.
  • the air pressure in the jack increases and, by reaction, the pressure on the felt increases.
  • the movement of the arm, and consequently the pressure exerted on the felt follow a preset program.
  • the position of the arm 8 is precisely defined at each instant.
  • the motor device 18 is thus advantageously a hydraulic cylinder or an electric motor controlled in position. Their power is chosen to be high enough so that the pressure exerted by the felt is practically without influence on the operation of the compression roller, unlike what occurs with the prior pneumatic cylinder.
  • the supply of the hydraulic cylinder in the case of the invention is carried out in the traditional way by a proportional distributor and a hydraulic group not shown.
  • the movement of the arm 8 is a function of the length of the wound felt and so that the thickness of each turn of the winding is practically constant.
  • the winder thus comprises at least means making it possible to determine at any time the length of felt wound, a sensor determining with precision the position of the arm 8, and calculation means in which the movement program of the arm 8 is stored.
  • the calculation means receive the signals relating to the length of felt and of the position signals of the arm, and elaborate in response a position instruction of this arm, instruction which is executed by the motor means (hydraulic cylinder, electric motor) indicated above. .
  • the signal is transmitted to programmable calculation means 23.
  • the calculation means 23 also receive from a sensor 24, for example a tachometric dynamo, a signal for the speed of progression of the conveyor 2 and consequently of the felt.
  • a sensor 24 for example a tachometric dynamo
  • the combination of the felt arrival signal and the speed gives the length of the coiled felt.
  • the calculation means also receive a signal from a position encoder 25 determining the angle of the arm 8 carrying the compression roller with respect to a reference position.
  • an additional sensor makes it possible to measure the initial height of the compression roller with respect to the conveyor 2. This determination is necessary when this height is modified to take account of changes in thickness of the products treated.
  • Figure 1 the means for changing the initial height of the axis 10 of the arm 8 are shown at 29. This is for example a system driven by a screw motor.
  • the measurement of the initial height of the arm 8 as well as that of the speed of the conveyor belt 2 can also be introduced by the operator directly into the data supplied to the calculation means. Indeed, these parameters usually remain constant during long periods of operation. Their variations are controlled by the operator who can therefore modify the data entered in the calculation means accordingly.
  • the means of calculation as a function of these data and of the control algorithm introduced into memory establish instructions which are sent to the commands 26 controlling the operation of the motor means 27 actuating the displacement of the compression roller, and also the means 28 actuating the movement of the back conveyor 11.
  • the felt strip 1 carried by the conveyor 2 passes in front of the photoelectric cell 22 and triggers a measurement of the time elapsed in the operating cycle.
  • the felt strip Before entering the space defined for winding, the felt strip is compressed by means of the roller 15.
  • the roller 15 is carried by the arm 8. It is driven like the compression roller 14 and rotates in the opposite direction.
  • the roller 15 makes it possible to prevent the felt from coming into contact with the roller 14 when it is introduced into the space in which the winding takes place. Indeed, the direction of rotation of the roller 14 is such that it would tend to repress the felt instead of facilitating its entry into this space.
  • the speed of rotation of the roller 15 is adjusted so that the speed at the periphery corresponds substantially to that of the conveyor 2.
  • the felt driven by the conveyor 2 strikes the back conveyor 11 and folds back on itself. From the conveyor 11, the end of the felt is directed towards the compression roller 14. The roller 14 forces the felt to bend again on itself. From the roller 14, the end of the felt is returned to the conveyor 2 where it comes into contact with the upper face of the felt.
  • a first loop of felt is thus formed.
  • the roller then progresses in successive thicknesses which are added to each other.
  • the compression roller 14 moves away from its initial position to take account of the increase in volume of the wound felt.
  • the movement is done in the direction indicated by the arrow F by tilting the arm 8.
  • the movement is programmed in order to ensure that all the turns of the roll formed have substantially the same thickness.
  • the thickness imposed is not necessarily exactly that which is found in the felt roll. It is indeed necessary to take into account the elasticity of the product and the deformations it presents during winding. In practice, the thickness imposed is generally less than that of the felt in the completed roll, and which is no longer maintained by the conveyors and the compression roller.
  • the arm 8 By deviating from its initial position, the arm 8 progressively increases the distance between the conveyor 2 and the roller 15. This distance becomes such that from a certain moment the roller 15 ceases to be in contact with the felt. The distance is then also sufficient so that the felt carried by the conveyor 2 does not come into contact with the compression roller 14.
  • a paper or polymer envelope is deposited on one of the faces of the felt.
  • the length of this envelope is such that it completely covers the exterior surface of the roller in a known manner.
  • the establishment of the envelope on the felt being made, the conditioning of the felt strip is completed for example by gluing the envelope so that it maintains the felt in its final compressed form.
  • the arm 7 moved by the jack 13 rocks.
  • the felt roll which is driven by the conveyor 2 is discharged through the opening cleared between the conveyors 2 and 11.
  • the arm 8 is returned to its initial position. Finally, the arm 7 is also returned to the working position. The reel is ready for processing a new strip of felt.
  • the felt kept compressed is not in strictly cylindrical form. It undergoes a slight crushing at the points of contact with the conveyors and the compression roller.
  • conveyors 2 and 11 makes it possible to maintain a relatively large contact surface, in particular compared to that of the compression roller 15. This indeed must necessarily have a small radius of curvature in order to be able to define a Small winding space at the start of the process.
  • the envelope introduction system is shown diagrammatically in FIG. 1.
  • the cut and partially glued sheets coming from a dispenser, not shown, and also controlled by the calculation means, are conveyed by a conveyor belt 30. They then pass on belts 31, in known manner, so that they are deposited on the end of the upper face of the felt strip at the moment when the latter will enter the winding space.
  • the envelope sheet is driven by the felt. It is taken in the last turn. This sheet extends beyond the end of the felt strip over a length greater than that of the periphery of the roll, so that it completely envelops it.
  • FIG. 3 are shown schematically the back conveyor 11, the horizontal conveyor 2, the compression roller 14 and the arm 8.
  • the movement of the arm 8 carrying the compression roller must be such that at all times the radius R of the roller already formed for a length 1 of the felt is: is:
  • a calculation based on the geometry of the system as presented in FIG. 3 makes it possible to express the variations of the angle A made by the arm 8 with the vertical at any time.
  • the calculation means check at all times that the position of the arm actually meets this condition.
  • the geometric conditions which have just been considered constitute only a series of parameters taken into account by the calculation means.
  • the main other parameters include those which depend on the nature of the felt rolled up: initial thickness, total length of the strip, mass per unit area, admissible compression ratio, etc.
  • the values of these parameters can be entered directly by the operator, either separately or globally, by referring to a code to which all the values stored in memory correspond, each product having its own code.
  • the packaging technique according to the invention was the subject of tests on an industrial line for the production of glass fiber felts.
  • the felts used consist of fibers produced by a centrifugation technique.
  • the molten material is passed through a centrifuge carrying at its periphery a large number of orifices of small diameters. Under the effect of centrifugal force the material is projected through these orifices out of the centrifuge in the form of filaments. These fine filaments are further drawn by hot gas streams along the periphery of the centrifuge at high speed.
  • the fibers produced are collected on a conveyor. On their way to the conveyor they are coated with a binder. The fibers collected are then passed through a treatment chamber in which the binder is polymerized. The sheet of fibers thus formed is cut to the appropriate dimensions. It is this sheet which is wound in the manner described according to the invention.
  • centrifugal devices In industrial plants, usually several centrifugal devices are aligned over the same conveyor.
  • the felts prepared during these tests are relatively light; their density varies from 6.8 kg / m 3 to 10.8 kg / m 3 .
  • the fibers are fine; the micronaire is either 2.5 / 5 g or 3.1 / 5 g.
  • the felts contain 4.5% by weight of binder.
  • the nominal thickness that is to say the thickness guaranteed to the user, is for all these products 90 mm.
  • an additional thickness is systematically provided in the felt before winding.
  • the thickness measurements are carried out in accordance with French standard NF-B-20.101. According to this standard, the thickness is measured under a conventional pressure of 50 N / m 2 . Measurements are made every 250 mm lengthwise, and 175 mm from the edges widthwise.
  • the values given in the table correspond to the average of the values measured over the entire length of the felt strip.
  • the values plotted on the graphs correspond respectively to the averages determined over five equal sections distributed over the entire length of the strip of felt.
  • the results are written from left to right, the left part representing the end located in the center of the roll and the right part representing the end.
  • the means proposed according to the invention also have the remarkable feature that they allow a very convenient modification of operating conditions. For this, it suffices to modify or complete the instruction program stored in the calculation means. No intervention is necessary on the mechanical elements of the device.
