Definitions

  • the present invention relates to the recovery and transport of a fibrous veil at the exit of the card.
  • She has main object a card equipped with a device which allows to detach and to transport at high speed a fibrous veil in exit of the last working cylinder from a card, without cause significant changes in the structure of the veil and in particular of stretching this veil.
  • a detaching cylinder small diameter which is adjacent to the last cylinder card worker, and who is rotated to the same speed and in the same direction as the last worker cylinder.
  • the last working cylinder will be for example a painter. whose function is to parallelize the fibers of the veil, or on the contrary a condenser having the function of blurring the fibers of the veil between them, so as to increase the cohesion of this veil in the direction transverse to the working direction of the card.
  • the surface outer of the cylinder is designed to allow the attachment of the fibrous veil over the entire periphery of the detaching cylinder, but with less adhesion than that of the veil on the last working cylinder. It could for example be a cylinder equipped with a isosceles lining or of a cylinder presenting longitudinal grooves around its entire periphery.
  • the second known type of detaching cylinder is in a perforated cylinder with a suction sector fixed opposite the last working cylinder.
  • a such a detaching cylinder has for example been described in the French patent N ° 1,500,746.
  • the fibrous veil arrives at the suction sector, it is plated on the periphery of the rotating detaching cylinder. Beyond this suction sector, the fibrous veil does not adhere theoretically more on the periphery of the detaching cylinder.
  • the aforementioned first type of detaching cylinder has the main advantage of allowing a more reliable recovery fibrous web at the periphery of the working cylinder.
  • the counterpart of this reliability is reflected by adhesion of the fibrous veil to the periphery of the detacher cylinder which is stronger than that of the sail fibrous at the periphery of the suction detaching cylinder, beyond the suction sector.
  • the object of the present invention is to provide a card equipped with a device which unlike the aforementioned devices of prior art, detaches and transports a fibrous veil at the end of the card, without causing modification in the structure of the veil, and in particular without causing this veil to stretch, and thereby to accelerate the rate of work of the card without harming the quality of the fibrous veil produced.
  • the veil when the veil comes in the depression zone created by the means suction between the detaching cylinder and the straight portion of the conveyor belt used for reception veil, under the combined effects of gravity and the suction, it detaches from the periphery of the detaching cylinder and is posed in the state on the surface and in the extension of the conveyor belt. This being trained roughly the same linear speed as the peripheral speed of the detaching cylinder, the web does not is not stretched lengthwise.
  • the distance between the rectilinear portion for receiving the veil and the periphery of the detaching cylinder must be sufficiently low, so that during its transfer, the veil does not undergo no flutter likely to deteriorate or cause transverse fold lines in the veil It is therefore preferable that this distance is equal or slightly greater than the thickness of the veil.
  • This distance value is not, however, limiting of the invention, since it has been possible in practice set this distance up to a value up to a hundred times the thickness of the veil produced, without observing deterioration of the veil, which is visible to the eye bare.
  • the suction flow created through the strip of the carrier should be enough to compress enough the veil in the region of the detaching cylinder so that the veil is no longer in contact with the periphery of the detaching cylinder, once placed on the straight portion of the conveyor belt.
  • the carrier of the device of the invention can be used to route the web from the last cylinder card, up to a device for treating this veil such as for example the rollers of a grille.
  • this conveyor belt can also be part of a machine arranged out of card. More specifically, this transporter may constitute the entrance apron of a machine, such as for example a lapper spreader.
  • the distance between the portion straight web for receiving the web and the periphery of the cylinder detacher will be adjustable so that it can be suitable for different thicknesses of sail.
  • the suction flow that is created through the portion straight of the conveyor belt must be sufficiently powerful to compensate for the adhesion of the fibrous veil at the periphery of the detaching cylinder. That power depends on several parameters, among which the grammage of the fibrous veil produced, the inclination of the rectilinear portion for receiving the veil with respect to the horizontal, and the type of detaching cylinder used.
  • the depression zone created by the suction means has the following characteristics. It extends at least over the entire width of the veil, which avoids any risk of folding of the edges of the web during its transfer between the cylinder detacher and conveyor belt; she starts at the line of quasi-tangency between the detaching cylinder and the rectilinear portion for receiving the veil, or upstream of this line of quasi-tangency, and extends downstream of the line of quasi-tangency on at least one radius of the detaching cylinder.
  • the terms upstream and downstream are here and in the rest of this text defined in relation in the direction of movement of the straight portion of reception of the veil.
  • the distance between the line of quasi-tangency, and the beginning of the depression zone located upstream of this line ie less than the radius of the detaching cylinder.
  • the depression zone created by the means of aspiration is not constant, and the depression grows continuously or almost continuously until a maximum of the depression zone, then decreases continuously until the end of the vacuum zone.
  • the maximum of the depression zone is located at the level of the quasi-tangency line, or downstream of this line, being distant from it by a radius maximum of the detaching cylinder.
  • a suction box with the suction face, located opposite the straight portion of the portion of the veil, consists of two planes inclined converging and separated by a suction slot, which is arranged substantially in one direction orthogonal to the direction of movement of said portion straight.
  • the suction slot corresponds to the maximum of the depression zone, the inclined planes allowing to decrease this depression, with a gradient depending on the inclination of each plane.
  • the another subject of the present invention is therefore also a card fitted at the outlet with at least two devices of the invention, and which are arranged to allow the superposition sails from their two detaching cylinders.
  • the carde is fitted with a single conveyor at the outlet band which is common to both devices.
  • each device having its own transporter to band a first carrier routes a first sail to the belt of the second transporter, so to position this first veil above and in the extension of the belt of this second transporter; the second transporter is equipped, in the area junction between the two strips, suction means which allow the first veil to be placed on the veil transported by the second transporter.
  • the last worker cylinder is shown in Figure 1 1 of a card, and a device 3 allowing detach the fibrous web 2 which is rolled up at the periphery worker cylinder 1, and to transport later this veil at high speed.
  • This device 3 consists of a detaching cylinder 4, a conveyor belt 5 and a suction box 6.
  • the detaching cylinder 4 is adjacent to the cylinder worker 1, and is driven in the same direction of rotation and with the same speed around its axis of rotation 7.
  • the periphery of this cylinder is equipped of a garnish 8 with isosceles points.
  • the transporter 5 has a strip with multiple perforations, and which this fact is breathable. Portion 9 of this strip shown in Figure 1 is straight, and passes close from the periphery of the detaching cylinder 4, in a direction orthogonal to the axis of rotation 7 of this cylinder spotter. She is also trained with the same linear tess that the peripheral speed of the detaching cylinder 4
  • the straight portion 9 of the conveyor belt 5 is inclined upward relative to the horizontal at an angle ⁇ .
  • This inclination is mainly conditioned by problems of space requirement of the conveyor 5 with respect to the main drum (not shown) of the card, and is linked to the position of the working cylinder 1 relative to this drum, as well as to the position of the detaching cylinder with respect to the working cylinder 1. It is therefore conceivable that this angle ⁇ is zero, which is illustrated in the example of card in FIG. 2C.
  • the spacing between the rectilinear portion 9 for receiving the web and the periphery of the detaching cylinder, that is to say in this case the tips of the lining 8, is represented in FIG. 1 by the distance e .
  • the position of the axis of rotation 7 of the detaching cylinder 4 was adjustable in a direction orthogonal to the rectilinear portion 9 for receiving the web, so that the distance e is adjustable as a function of the thickness of the web.
  • the suction box 6 is positioned opposite the detaching cylinder 4, on the other side of the straight portion 9 of the conveyor belt, and creates a vacuum zone 10 of width L between the detaching cylinder 4 and the straight portion 9 of the conveyor belt 5 which straight portion 9 comes almost to the tangent of the detaching cylinder along a line T called the line of quasi-tangency.
  • the vacuum zone 10 begins upstream and at a distance d from the line of quasi-tangency T, with respect to the direction of movement D of the strip 9, and extends in downstream of this line of quasi-tangency, over a distance of .
  • the web 2 When the web 2 arrives at the beginning of the vacuum zone 10, it begins to detach from the periphery of the detaching cylinder 4, at point B, under the combined effects of gravity and the suction flow created by the box 6 at through the strip 9. As a result, the web 2 is placed on the strip 9 at the level of the quasi-tangency line T and is held on the surface of this strip 9 until the exit from the vacuum zone 10.
  • the distance e must be sufficiently small so that the web 2 does not undergo deformation in particular under the effect of its own weight or the air flow generated by the rotation of the detaching cylinder 4, when it passes from the periphery of the cylinder detacher 4 to the conveyor belt 5.
  • the fibrous veil is driven without sliding on the surface of the strip 9 of the conveyor, by the thin layer of air which is generated by moving this strip.
  • Speed of the web is therefore identical to the speed of the web of the carrier. This being also identical to the speed periphery of the detaching cylinder 4, this results that the fibrous veil does not undergo any stretching. It suits note that in practice it is possible to tolerate a speed variation of up to 2% between speed linear of the conveyor and the peripheral speed of the detaching cylinder, without this variation causing a change in the structure of the veil which is harmful the quality and cohesion of the veil produced.
  • the suction box 6 has a suction face formed by two converging inclined planes 11 a ; 11b , substantially forming a V and separated by a suction slot 12, which is arranged in a direction orthogonal to the direction of movement D of the straight portion 9 of the conveyor belt 5.
  • This suction face extends preferably over the entire width of the web 2 so that the vacuum zone between the conveyor belt and the detaching cylinder 4 reaches the edges of this web.
  • This suction box 6 creates a variable vacuum zone, which increases from point B to a maximum at the suction slot 12, then decreases until the end of the vacuum zone. The speed of the suction flow generated by this suction box through the straight portion 9 of the conveyor belt 5 is therefore maximum at the suction slot 12.
  • the depression zone 10 must allow at least compensate for the adhesion of the fibrous veil to the periphery of the detaching cylinder 4, as well as the effects of turbulence created downstream of the quasi-tangency line T. Les characteristics of this depression area depend mainly of the type of detaching cylinder used, the grammage of the fibrous veil produced and the angle of inclination ⁇ of the straight portion 9.
  • the radius r of the cylinder with isosceles lining was approximately 80 mm; the suction box 6 was positioned so that the distance d was about 20 mm, and the distance d was substantially equal to the radius r ; the speed of the suction flow. measured between the detaching cylinder 4 and the straight portion 9, at the suction slot 12, was between 1 and 2 m / second; the angle ⁇ could vary in absolute value between 0 and 90 ° and the distance e was adjustable in 0 and 50mm.
  • suction box 6 which has been described by any type of suitable suction means. More particularly, it is possible to use a suction box creating a vacuum zone with vacuum gradients which are different upstream or downstream of the suction slot 12, which results in a different inclination of the two convergent planes 11 a , 11 b .
  • the veil fibrous product When the card starts, as long as it has not reaches its normal operating regime, the veil fibrous product has a reduced thickness and a lower grammage. Therefore, in order to avoid any risk of the fibrous veil wrapping around the periphery of the detaching cylinder 4, when the card starts, it is possible within the framework of the invention to increase the flow suction generated by the box 6, until the has reached its normal speed and the veil is producing has the required weight characteristics and thick.
  • FIGS. 2A, 2B and 2C show three possible examples of configuration at the card outlet, allowing the parallel production of two fibrous webs, and their overlap.
  • the drum principal of the card is referenced 13.
  • the first way upper outlet consists of a counter drum 14, a comber 15, and two successive condensers 16 and 17; the second lower exit route is constituted by a counter-drum 18 and a painter 19
  • These two exit channels are equipped respectively of a device 20,21, which is similar to that of the figure 1
  • the detaching cylinder and the suction box of each device are respectively referenced 22 and 23; the last condenser cylinder 17 for the upper track and the comb cylinder 19 for the lower track correspond to worker cylinder 1 of the Figure 1.
  • this transporter belt has a straight portion 24, which is used for the reception of the two fibrous webs at level of the two devices 20 and 21.
  • the first fibrous veil, coming from the lower route is conveyed by this rectilinear portion 24 up to the entrance to the depression created by the suction box 23 of the device 20 of the upper track.
  • the second fibrous veil from the pathway upper is superimposed on the first fibrous veil, the suction flow created by the suction box allowing both to maintain the first fibrous veil from the route below the surface of the straight portion 24 and detach the second fibrous veil from of the upper track to superimpose it on the first veil fibrous.
  • the detaching cylinder 22 and the suction box 23 of the device 20 of the upper exit route are positioned on the side and on the other side of the rectilinear portion 25 of the belt conveyor, just downstream of the change of direction of the strip of this carrier.
  • This variant embodiment presents the advantage of avoiding the risks of detachment of the fibrous veil when changing the conveyor's direction.
  • the first fibrous veil from the lower track arrives at the level of this change of direction, it is held on the surface of the transporter due to the presence of the suction box 23 just downstream of this change of direction.
  • each device 20, 21 has its own conveyor belt 26, 27.
  • the detaching cylinder 22 of each device 20, 21 is located substantially vertically respectively of the condenser 17 and the doffer 19.
  • the conveyor 27 is horizontal.
  • Conveyor 26 is tilted down and allows the routing of the fibrous veil from the path above the surface and in line with the transporter 27. The superposition of the two fibrous webs from the card is therefore carried out at the junction zone 28 between the two conveyors 26 and 27.
  • suction means whose function is on the one hand to maintain the first fibrous veil from the lower pathway on the surface of the transporter 27 during the superposition of the two sails and on the other hand to lay the veil on this conveyor 27 fibrous conveyed by the transporter 26
