Definitions
- the present invention relates to an installation for recovering waste from the manufacture of glass strands.
- the manufacture of reinforcing glass strands results from a complex industrial process which consists in obtaining strands from molten glass threads flowing through die orifices. These threads are drawn in the form of continuous filaments, then these filaments are gathered into basic threads, which threads are then collected in the form of windings.
- the filaments are usually coated with a sizing composition by passing over a sizing member.
- This deposit of size is very important: on the one hand, it makes it possible to obtain the wires, on the other hand, it allows these wires to be used effectively in the production of composites.
- Sizing has indeed the following usual functions: it protects the threads from abrasion and thus prevents their breakage during their manufacture and, possibly, during their use, it allows the association with organic and / or inorganic matters to be reinforced. , in particular by facilitating the wetting and / or impregnation of the wires with these materials. In most cases, the size also promotes adhesion between the glass and the material to be reinforced and makes it possible to obtain composites having improved mechanical properties.
- the winding is carried out using winders, which as their name suggests, are responsible for winding the sized glass wires at very high speed. Taking into account the rotational and displacement speeds reached and as a consequence of the centrifugal force, migrations are created from the size towards the surface of the winding, these migrations being in the form of excess sizes in some places and / or gaps in others. These migrations modify the properties of the glass strands, making it difficult to market the windings as they are. On the other hand, at the end of the winding of each winding, the wire is broken and its end forms a few turns tangled in each other: this part of wire is unfit for use and must therefore be eliminated.
- the demand for glass wire thus cut is estimated at around 5000 T / year.
- cutting devices for glass wire are known. A distinction is thus made between cutting machines for reinforcing wire. In general, it is a rotary knife machine which is suitable for cutting strands of wire with very high cutting speeds. However, these machines and their rotary knives allow these high cutting speeds to be achieved only over a reduced range of tex and any variation, even very small, results in a modification of the cutting parameters, or even a modification of the cutting member. For glass yarns of a larger tex, cutting devices are used provided with guillotine or cleaver knives. These members can accept variations in the tex range, but are very limited in the cutting speed range. Given the inertia of the cutting system, the cutting speeds achieved are very much lower than those obtained with cutting machines with rotary knives.
- the previous cutting systems are dedicated to a given tex value; however, in the context of the recovery of waste from in particular the peeling of windings, the user has a large number of windings whose tex values can differ from one winding to another and there n it is not possible to envisage peeling a first family of windings according to a given value of tex, then a second family of windings according to a different value of tex (smaller or larger), the system cutting must therefore be adapted to these tex value ranges regardless of the type of glass wire feed.
- the object of the present invention is to propose a plant for the production of cut glass wire which is integrated into an existing production line and which is suitable for cutting strands of wire in a wide tex range and at speeds. high cutting.
- the installation for producing strands of glass wire comprising a cutting unit formed by a cutting device with rotary blades and a counter blade positioned opposite said cutting device, the cutting unit being adapted to cut the glass strands when the latter pass through said unit, characterized in that the installation comprises: - a first glass strand engagement device adapted to receive said glass strands from at least one feed unit, a drive device located downstream of said first engagement device, the drive device being adapted to drive the glass strands towards the cutting unit positioned downstream of said drive device,
- the first engagement device comprises a suction member of the venturi type
- the drive device comprises at least two guide members positioned opposite one another, said guide members being driven in rotation in opposite directions and without sliding by a drive member, said members delimiting between - a variable space suitable for the passage of glass wires,
- the guide members are provided with a heat exchange device allowing the temperature of said guide members to be controlled
- At least one of the guide members comprises a device for adjusting the intensity of the pressing force exerted by said guide member on the glass strands traveling through the space defined between the members,
- the second engagement device comprises a suction member of the venturi type
- the evacuation device comprises a conditioning unit adapted to collect the strands of glass wire, said conditioning unit being provided with an airlock adapted to empty a determined quantity of strands of glass wire,
- the packaging unit is provided with a cleaning device.
- it also relates to a process for recovering waste resulting from the peeling of windings within the installation described above. which is characterized in that: at least one glass wire is introduced from at least one of the internal and / or external ends of a winding within the first engagement device,
- the glass wire is cut into a plurality of strands within the cutting unit, the glass wire strands are extracted by gravity separation.
- the first engagement device conveys the glass wire by suction towards the drive device
- the glass son is guided downstream of the drive device using the second engagement device
- strands of glass wire as a filtration or soundproofing element, or even as a carpet underlay, or even as a as mechanical reinforcement associated with a matrix of organic fibers for the manufacture of shelves, interior trim panels or the like.
- FIG. 1 is a schematic view of the installation which is the subject of the invention
- FIG. 2 is a perspective view of the drive device in a first position of the guide members
- FIG. 3 is a perspective view of the drive device in a second position of the guide members
- - Figure 4 is a perspective view on a larger scale of the guide members.
- FIG. 1 there is shown the diagram of an installation intended to be integrated within a winding peeling installation operating continuously.
- the windings take the name of “roving”, but it can be considered that the installation illustrated in FIG. 1 could without substantial modification be integrated into an installation operating discontinuously, this installation being simply considered as a glass wire supply unit.
- a plurality of glass strands from a wire feed unit (winding, cake, roving ...) having dispersed tex values is routed to a first engagement device 1 shaped as a venturi.
- a “cake” is a winding of glass fibers resulting from a fiberizing operation, this cake not having, moreover, a cylindrical shape. Thanks to the vacuum formed by the venturi, the glass strands are directed towards the drive device 2.
- This drive device 2 is particularly suitable when it comes to integrating the installation object of the installation into a continuous process.
- the engagement device 1 is fixed on a metal frame (not shown in the figures) and has a vacuum setting using a flow of compressed air which ensures the suction at the level of the venturi neck .
- This drive device 2 On this chassis is mounted the drive device 2 which is shown in detail at the levels of FIGS. 2 and 3.
- This drive device 2 mainly comprises two guide members 3, 4 positioned opposite one another and forming a jaw. Each part of this jaw is produced by a guide member 3, 4, one of the parts of the latter being secured to the chassis, the other part being articulated with respect to the chassis so as to achieve an angular movement with respect to the first fixed part.
- the amplitude and intensity of this angular movement between the two guide members 3, 4 are adjusted by an actuator 5 of the pneumatic or hydraulic cylinder type, the rod of the cylinder being connected to the movable part of the jaw, the body of the cylinder with a fixed part secured to the chassis.
- the glass strands from the first engagement device 1 are intended to travel within the space defined by the two parts 3, 4 of the jaw.
- the glass strands are sandwiched between two generators each belonging to a guide member 3, 4.
- These guide members 3, 4 shown in perspective in FIG. 4 are formed by a train of rollers, in particular cylindrical, motorized, one of the rollers is connected to a motor, the other is driven by the previous one according to a opposite direction of rotation. It can also be provided that at least one of the guide members 3, 4 is provided with a cooling member which by thermal conduction with the glass strands dissipates calories from friction.
- the guide members consist of rollers having a peripheral surface comprising a plurality of raised areas.
- a second engagement device 6 In the continuity of the path of the glass strands and downstream of the drive device 2 is disposed a second engagement device 6, also fixed to the frame of the installation.
- This second device 6 is similar to the first and includes a venturi system making it possible to ensure, by suction, the recovery of the glass strands at the outlet of the drive device 2 in the direction of the cutting unit 7.
- the second engagement device 6 will be eliminated.
- the cutting unit 7 is of known type, it is a combination of a blade rotor 8 and a counter blade 9, the glass strands passing between the blade 8 and the counter blade 9.
- L 'cutting unit 7 constitutes a second unit for adjusting the installation flow rate. Indeed, depending on the number of blades, their rotation speed, the cutting speed will be adapted to that of the drive device 2.
- the other units shown in Figure 1 can be separated from the main installation. This is in particular the packaging unit 10 formed mainly by a hopper which collects the strands of glass wire which have been previously sucked from the cutting unit 7. By gravity separation, the strands of son fall into a lock. 11 situated in the lower part of the hopper, this lock 11 ensures the unloading of the strands at regular intervals to a conveyor 12 which ensures their transport to a bagging unit 13.
- a pressurized fluid circuit compressed air for example
- this fluid causing the hopper to be agitated and therefore the separation of the possibly agglutinated strands.
- the strands of glass thread are particularly suitable for serving as mechanical reinforcement with mineral or organic fibers in the manufacture of tablets, plaster tiles or the like.
