Definitions
- the present invention relates to the field of manufacturing cut son high performance material, or son thermoplastic material, including glass son, and more specifically relates to improvements made to a cutting wheel.
- a cutting device most often constituted by a "cutting wheel” equipped with a multitude of blades whose relative spacing contributes cutting the fiber to the desired length and a cutting wheel referred to as “anvil wheel” usually consisting of an elastomeric tire overmoulded or attached to a removable rim fixed on the cutting machine.
- anvil wheel usually consisting of an elastomeric tire overmoulded or attached to a removable rim fixed on the cutting machine.
- the continuous cutting of the fiber is obtained by the high speed rotation of this wheel assembly and the pressurization of the cutting wheel on the anvil wheel by means of a suitable clamping means.
- the cutting wheel and anvil wheel must ensure that:
- the fiber cutting quality in particular its density and its dynamic integrity, is directly related to the suitability of the materials involved (constituting the blades and the wheel against) to retain their characteristics (conservation of the geometric parameters of the blades, resistance to abrasion wear and notches of reelastomer anvil wheel).
- the first major difficulty to solve in section under die is the ability of the wheel to cut the fiberglass while stretching at high speed without slippage.
- the cut element has a tendency to jam between the two consecutive blades by bracing effect, to avoid that each turn of cutting wheel elements are packed between the blades and lead to a generalized jamming of the system, it is necessary that a particular device exerts an extraction force which ejects the cut strand off the blades and this just after the cutting zone.
- Cutting wheels comprising, on the one hand, a support member consisting of a rotating elastomer drum and, on the other hand, blades arranged perpendicularly to its periphery and, between the blades, members to be secured under the belt.
- the effect of the centrifugal force is the succession of following steps: the compression of the wire against the surface of a support drum for its drawing, the cutting of the wire and the ejection of the cut sections.
- the members which provide the compression of the wire are constituted by fins secured to a deformable ring, generally based on elastomer, for example polyethylene, disposed under the base of the blades and whose axis coincides with the axis of rotation of the cutting wheel. These wheels cutting are satisfactory and meet the requirements mentioned above.
- the inventors have sought the origin of the phenomenon which causes a limitation of the cutting speeds achieved.
- the blades tend to shorten and generate a heating and softening at their support zone with clamping rings positioned on both sides of the deformable ring, these rings exerting their clamping force on inclined surfaces of the blades.
- clamping rings positioned on both sides of the deformable ring, these rings exerting their clamping force on inclined surfaces of the blades.
- a lateral clearance is created at the clamping zone with the blades, which generally leads to their breaking.
- the present invention proposes to provide a solution to all of these constraints by proposing an improved cutting wheel technology which allows high cutting speeds and a greater number of dies.
- the cutting wheel intended to cut continuous son in sections of a predetermined length, comprising a support member consisting of a rotary drum equipped with blades arranged perpendicularly to its periphery and, between the blades, organs to ensure under the effect of the centrifugal force the compression of the son against the surface of a bearing drum, and then cutting the son in sections, and the ejection of the cut sections, the members ensuring the compression of the son being constituted by fins secured to a deformable ring disposed under the base of the blades and whose axis coincides with the axis of rotation of said cutting wheel is characterized in that the deformable ring comprises on each side a parallel right flank extending from the base of the ring deformable to the base of the fins.
- the deformable member is at least in two parts, a spacer separating the two parts and is mounted concentrically with respect to the axis of rotation of the drum and the toe serving as a fulcrum to said blades between their two ends ,
- the blades are, on the one hand, immobilized at their ends and on the other hand rest at the level of at least one point situated between its ends,
- the ends of the blades are held at the bottom of the slots made in the rings using a pair of elastomer rings and a pair of flanges, said flanges being adapted to induce clamping stresses at the level of the elastomer rings.
- the flanges and the elastomer rings are mounted face to face, concentrically to the axis of rotation of the drum, all or some of the parts selected from the flanges, the elastomer rings, the rings, are symmetrical parts,
- the deformable member comprises a ring provided at its periphery with a plurality of fins, the fins and the ring forming a monolithic assembly,
- the fins and the ring are made of different materials
- a space is provided between two contiguous fins and is delimited by the connecting surface between the base of the fins and the base of a blade,
- the upper face of the fins describes a cylindrical surface of revolution whose radius is different from that of the circle passing through the top of the cutting edge of the blades;
- the distance between the two rays is a few tenths of a millimeter.
- a cutting machine intended for the manufacture of cut yarns for technical use, in particular yarns made of thermoplastic material and especially glass yarns, said machine comprising a three-dimensional chassis having three sides or more, at least one cutter assembly secured to one side of said frame, said cutter assembly using a cutting wheel as previously described and an anvil wheel.
- FIG 1 is a schematic view of the general implementation of the device and associated equipment for stretching continuous filaments of glass from a plurality of sources
- FIG 2 is a schematic perspective view of the various parts constituting the cutting wheel according to a first embodiment
- FIG 3 is a schematic perspective view of the different parts constituting the cutting wheel according to a second embodiment
- FIGS. 4 and 5 are schematic partial sectional views of a cutting wheel and an anvil wheel in various cut length configurations.
- Figures 6 and 7 are schematic views of the embodiments illustrated in Figures 2 and 3.
- the production line shown schematically in Figure 1, comprises upstream at least one die 10 fed from molten glass or glass beads by a not shown feed device.
- the die (s) generally made of rhodium-plated platinum and heated by the Joule effect, are provided at their lower part with a plurality of orifices from which a plurality of filaments 11 are stretched mechanically.
- These filaments forming at least one sheet are coated with a lubricant sizing product, commonly called sizing, by passing on a coating device 12, before being joined in the form of son by assembly rollers 13.
- the son 14 thus formed are fed by means of return pulleys 15 to a guiding device 16, for example a comb, before being introduced into the cutting machine 17 composed of a support drum 18 (commonly called a wheel anvil) and a blade drum, commonly referred to as a cutting wheel 19.
- a guiding device 16 for example a comb
- a blade drum commonly referred to as a cutting wheel 19.
- the stretching is obtained solely by the action of the cutting device whose operation will be described later; it could also be performed by an auxiliary drawing device, placed upstream of the cutting device, such as those described in US Pat. No. 3,873,290.
- the cutting device according to the invention can be arranged in various ways its arrangement will depend on the means used upstream to guide and stretch the son, as well as the implementation of the receiving device cut son.
- Figure 1 shows a conventional arrangement for projecting vertically cut son.
- the structure of the cutting wheel 19 according to two distinct embodiments are shown in FIGS. 2 and 3.
- the cutting wheel 19 comprises a hub 20 (visible in FIG. 1) and clamping flanges 21a, 21b enclosing the different fastening elements of the cutting blades 22.
- the rings 24a and 24b are concentrically mounted on the hub 22.
- the rings are concentrically mounted to the axis of rotation of the cutting wheel 19 by bearings and are clamped against each other between the clamping flanges 21a, 21b, the assembly being secured by locking members (screws for example).
- Flexible rings 25a, 25b made of elastomer are placed between the clamping flanges 21a, 21b and the sidewalls of the rings 24a, 24b, resting on the bevelled faces of the cutting blades.
- the depth of the grooves 23 is greater than the height of the blades.
- the rings 24a and 24b are made of steel and they keep the blades apart.
- the clamping flanges 21a, 21b are made of steel and undergo a heat treatment (chromium supply) and serve as a support for the bottom of the blades. (In case of wear, it is easier and more economical, to recondition the flanges 21a, 21b rather than the crowns 24a, 24b)
- deformable member 26, 27a, 27b there is disposed under and between the blades a deformable member 26, 27a, 27b, preferably of elastomer.
- the cutting wheel 19 comprises a single deformable member 26 trapped between the clamping flanges 21a, 21b.
- FIGS. 3 and 7 it is a cutting wheel 19, called a wide wheel, particularly designed for production volumes of large chopped wire sections.
- This cutting wheel generally incorporates the components of the preceding cutting wheel and differs from them.
- a second deformable member 27b in fact the deformable member 26 has been separated into 2 parts 27a and 27b so as to be able to place a crown 29 of support
- the two deformable members 27a, 27b being axially separated by a spacer 28 allowing the blades 22 to have a point of support substantially equidistant point of their ends.
- a central ring 29 positioned coaxially with the spacer 28 is provided on its periphery with a plurality of radial slots 30 for the passage of the cutting blades 22.
- the deformable member 26 (or the plurality of deformable members 27a, 27b in the case of Figure 3), located under the blades 22, consists of an elastomeric ring whose edges are erected over the entire diameter so to present a flat bearing surface so as to exactly match the cylindrical bearing surfaces of the rings.
- the deformable members 26, 27a, 27b are integral with the ring forming the central part and protrude on its upper surface in the form of fins arranged at the pitch of the blades 22 and coming to be housed, with a certain clearance, in the free spaces between said blades.
- These bodies thus form a deformable fin crown, which is preferably monolithic; this ring, freely mounted without clamping, is positioned angularly and is kept centered not rigidly through the rings 24a, 24b.
- the upper face of the fins describes a cylindrical surface of revolution whose radius is different from that of the circle passing through the top of the cutting edge of the blades, and the difference between the two radii is a few tenths millimeters.
- the blades 22 are held at their ends, by means of flexible contacts, against the rigid contacts formed by the bottom of the radial slots 23 of the rings 24a, 24b and at least located between the ends, this point resting on the central crown door 29 (in the embodiment shown in Figure 2, the central point support does not exist).
- the cutting wheel 19 thus assembled is mounted on a rotating hub 20 shown in Figure 1, and is centered on it by means of a cone; the fixing of the cutting wheel on the shaft is ensured by screws.
- the axis of rotation of the wing crown then coincides with his.
- the deformable members 26, 27a, 27b annular and its fins are made of elastomer, for example polyurethane whose Shore hardness, scale A, is between 80 and 100. It is also conceivable a bi-material embodiment, the heart of the member in a first plastic with an overmolding of a second plastic material forming the fins, the first and second plastics material may have different mechanical properties, especially in terms of hardness.
- the cutting wheel 19 cooperates with an anvil wheel 18.
- the surface of the latter is covered with a flexible layer made of elastomer, for example made of polyurethane identical to that constituting the finned ring previously described.
- the distance separating the axes of rotation of the drums 18 and 19 is adjusted (by applying a clamping pressure) so that the cutting edge of the blades penetrates shallowly into the coating of the bearing drum (the deformation of the elastomer layer limits the blade penetration).
- the diameter of the finned crown is such that, when the cutting device is stopped, the upper faces of the fins do not exceed the level of the cutting edge of the blades.
- the motor movement is given preferably to the cutting wheel 19, which sets in motion the anvil wheel 18, mounted free on its axis. The movement is transmitted simultaneously by the action of the fins on the coating and by meshing resulting from the slight penetration of the blades in said coating.
- the thickness of the annular portion of the deformable member 26, 27a, 27b is determined according to the modulus d ⁇ oung elastomer material constituting said member, so as to have a correct expansion of the fin (which serves point of support with the threads during the drawing phase, and then during the cutting phase into sections of cut threads), for the desired cutting speed ranges.
- Figure 4 shows the operation of the device according to the invention adapted, the manufacture of relatively long cut strands.
- the cutting wheel 19 comprises a finned ring whose upper faces reach at the cutting edge of the blades when the cutting wheel is stopped.
- the deformable member and the fins have undergone a slight radial expansion caused by the centrifugal force and, under this effect, the succession of the upper faces of the fins then forms a cylindrical surface of revolution. almost continuous, whose radius is greater than that of the concentric circle passing through the top of the cutting edge of the blades.
- the cylindrical surface of revolution and that of the coating come in contact, pinch the wire or son and cause their stretching, prior to cutting, by this single action.
- the pressure exerted by the fin on the glass wire is independent of the clamping pressure exerted between the axes of the two wheels (cutting and anvil). This pressure is constant and depends only on the nature and geometry of the deformable member.
- the cutting wheel 19 also comprises blades whose spacing is such that the cutting work is performed by a single blade at a time.
- the fins are pushed inwards under the action of the pressure exerted by the surface of the anvil wheel 18; under this action, the annular portion of the deformable member deforms radially inwardly in the space above the crown door.
- the rotation drive of the anvil wheel by the driving cutting wheel is provided essentially by the close cooperation of the cylindrical surface of revolution with that of the coating; this results in compression of the cut strand which is attenuated by the radial shrinkage of the wing crown and is not large enough to impair its integrity.
- FIG. 5 shows the operation of another variant of the device according to the invention, suitable for cutting a wire into short lengths-for which the spacing of the blades is such that the cutting work is carried out simultaneously by at least two blades.
- the integrity of the cut strands is all the more difficult to maintain as the contact points between the different elementary filaments forming the strand are fewer, which is particularly the case when reducing the length of the strands.
- the loss of cohesion can occur either as a result of the crushing of the strand between two surfaces strongly pressed against each other, or as a result of the shearing occurring during the cutting of a strand insufficiently maintained during this operation.
- the operating mode of the cutting system illustrated in Figure 5 is as follows: the son are driven by the only traction resulting from its adhesion to the surface of the coating of the wheel anvil. In the actual cutting zone, the wires come into contact with the cutting edge of a first blade, then are trapped and held between the surface of the coating, the upper face of a fin and the next blade which initiates the cutting of the blade. strand. In contact with the coating, the fins are pushed back but slightly and under a lower pressure than in the previous case. The cut strand is thus maintained simply clamped between the two elastomeric surfaces and retains all its integrity.
- the fins emerge by ejecting the cut strands.
- the rotational drive of the anvil wheel by the driving cutting wheel 19 is ensured essentially by the penetration of the blades in the coating of the anvil wheel.
- a cutting wheel provided with blades arranged perpendicular to its periphery and inclined relative to its axis of rotation at an angle between 10 and 30 °
- the cutting device is set so that the cutting blades penetrate shallowly into the coating of the anvil wheel, this adjustment being corrected whenever the deterioration of the surface of said coating will require rework.
- the deformable member is chosen so that even after radial expansion caused by the centrifugal force, the upper faces of the fins describe a circle whose radius is slightly smaller than that of the concentric circle passing through the top of the cutting edge of the blades. In operation, a gap of 5/10 mm was measured.
- the characteristics of the deformable member (s), and mainly the distance between the rays of the concentric circles described by the upper faces of the fins and the top of the cutting edge of the blades, will be chosen in particular. according to the desired length for the cut strands.
- This difference is of the order of a few tenths of a millimeter, for example from -2 / 10 to + 3/10 millimeters taking as a reference radius that of the circle passing through the top of the cutting blades.
- the device of the invention combines many advantages, including the following:
- the deformable fin member maintains the integrity of the wire sections and eject them out of the cutting area.
- the deformable fin member prevents clogging of the cutting wheel.
- the cutting wheel which is driving and keeps a constant diameter, avoids the changes of adjustment of the speed of rotation.
- the cutting wheel is easy to assemble and disassemble when it becomes necessary to change one or more blades.
- the majority of the parts constituting it is symmetrical, which facilitates the assembly and decreases the number of pieces in stock.
- the structure of the cutting wheel also has the advantage of being able to modify the length of the sections of wire by a quantity that is a multiple of the pitch of the grooves. (It is possible to alternate between the cutting blades, non-cutting blades, in order to vary the cutting pitch) Indeed, for a given deformable fin member, the adjustment of the length can be easily obtained by inserting between two successive cutting blades one or more blades devoid of cutting edge and whose height is such that they do not touch the surface of the support drum in the cutting zone. The insertion of these blades is intended to keep in place the deformable fin member and avoid significant deformations that would cause its rupture.
