Definitions
- the present invention relates to a process for cleaning bobbins, in order to remove fibrous residues from a textile material wound on these bobbins, comprising - supplying the bobbins to a cleaning station,
- It also relates to a device for cleaning such coils.
- the conveyor of the device must advance step by step and stop at each cleaning operation of a coil. This results in poor performance of the device.
- the fibrous residues cut at the top of the spools fall towards the base thereof, remaining retained by the base flange of the spool and thus accumulating above the fibrous residues wound around the lower part of the coil. They can also hang on the lower sprinklers. This has the effect of complicating the cutting of the fibrous residues located near the base flange and of not allowing perfect cleaning of the coils. It is also necessary to determine the number of oscillations of the nozzles necessary to completely cut the fibrous residues according to a certain number of variables, such as the quantity of fibrous residue adhering to the coil, as well as the fouling and the condition of the coil.
- Patent US-A-5297952 provides an apparatus for inspecting the cleaned coils with redirection of the coils which are not completely cleaned towards an additional passage in the cleaning station. Installations comprising these devices according to the prior art also only recover the cleaned coils. They are very large consumers of water and no recovery of other products from the cleaning process is planned. The cut fiber residues, or the coils cleaned, but damaged, and therefore considered non-reusable, are simply disposed of in landfill.
- the object of the present invention is to develop a method and a device for cleaning coils which overcomes the aforementioned drawbacks and which allow continuous cleaning of the coils and maximum recovery of all waste, in particular glass fiber. This recovery must be maximum, and it must in no case cause a disturbance in the operation of the machine itself, whether it be means of transport, sprinklers, or other parts located in the cleaning station.
- a method for cleaning coils as described at the start which is characterized in that it further comprises, during and after said cutting, an unhindered fall of the cut fibrous residues, by gravity, in a means of harvest.
- the coils are thus freed as much as possible of the fiber residues they carry, before leaving the cutting station where the jets of fluid take place. In an extremely simple way, the fibers fall unimpeded, for example into a collecting tank.
- the fibers fall directly into the harvesting means without encountering anything, or that they fall into the latter in being guided by a guide means, such as a deflection plate on which they slide without being able to hang on to it.
- a guide means such as a deflection plate on which they slide without being able to hang on to it.
- the fibrous residues fall without clinging either to another part of the coils, or to the nozzles themselves, or to the continuous conveyor which drives the coils.
- the direction of transport is horizontal.
- said at least one jet of fluid under high pressure is fixedly directed onto the coils in a plane passing through the longitudinal axis of the coils, and particularly advantageously it is directed obliquely, in particular from the top, onto the coils.
- the coils can be of different shapes and dimensions and carry more or less residue and the angle of inclination in particular of the jets on the coils is of great importance.
- the method further comprises, at the end of or after cutting, spraying the coils with at least one jet of fluid at a pressure lower than those presented by the jets of fluid under aforementioned high pressure, with a humidification of the fibers having undergone cutting.
- the fiberglass, once cut, is thus weighed down by impregnation of the fluid, which facilitates its sliding from the coils, under the effect of gravity.
- the method comprises a draining of the fibrous residues collected in the harvesting means.
- the method comprises, before cleaning, elimination from the reels of any waste not made up of said fibrous residues and a treatment for revalorization of the cut fibrous residues, after the harvesting thereof. this.
- a treatment for revalorization of the cut fibrous residues after the harvesting thereof.
- the revalorization treatment can comprise, according to the invention, a drying of the cut glass fibers after draining, a cutting of the dried glass fibers into cut fibers, and optionally an opening of the cut glass fibers glass wool, by carding.
- the present invention also relates to a device for cleaning reels to remove fibrous residues wound on these reels, this device comprising a continuous conveyor of the reels in a direction of transport, on which each reel transported has a longitudinal axis parallel to the direction of transport, and a cleaning station crossed by the continuous conveyor and provided with at least one nozzle which is directed on the coils which pass and which produces a jet of fluid under a sufficiently high pressure to cause cutting of the fibrous residues carried by the coils.
- the device comprises at the bottom of the cleaning station a collecting tank, in which the cut fibrous residues fall by gravity, without hindrance.
- the continuous conveyor comprises an endless drive means and reel supports, which are carried by the latter in overhang and on which the reels to be cleaned are arranged.
- the endless drive means for example a chain. This arrangement greatly reduces the risk of the fibers catching on the chain itself, during their fall.
- the device comprises, in the cleaning station, an arrangement of at least three aforesaid nozzles each producing a jet of fluid under high pressure fixedly directed obliquely downward on the coils, in a plane passing through one longitudinal axis of the coils.
- the device according to the invention may comprise, in the cleaning station, after said at least one nozzle at least one spray element which is fixedly directed on the coils which pass and which produces a jet of fluid under a pressure lower than said high pressure of the jets of said at least one nozzle.
- This spray element has the function of wetting the fibers and thus improving their fall by gravity from the reels.
- the device according to the invention comprises means for adjusting the relative position of said at least one nozzle with respect to the coils which pass. Indeed depending on the size or shape of the coils passing or the thickness of fibrous residue to cut the jets of the jets will have to be oriented and inclined differently.
- the device according to the invention comprises a speed variator of the continuous conveyor of the coils.
- a speed variator of the continuous conveyor of the coils it may be desirable to slow down or speed up the speed of passage of the coils through the cleaning station.
- a reel sorting can be carried out beforehand in order to be able to launch a large number of reels at the same speed and with the same inclination and orientation of the nozzles before having to change these data.
- Figure 1 schematically shows an embodiment of the coil cleaning device according to the invention.
- Figure 2 shows an arrangement of sprinklers and spray elements in the cleaning station.
- Figure 3 shows a sectional view through the cleaning station.
- Figure 4 shows a top plan view of a spool holder on a conveyor chain.
- Figures 5 and 6 show a sectional view and a plan view of a device for ejecting the cleaned coils.
- FIG. 7 shows, schematically, the recovery lines of harvested fiber residues and damaged coils as well as the recycling of water.
- identical or similar elements bear the same references.
- the cleaning device according to the invention comprises an endless conveyor chain 1 by which the coils 2 are transported.
- the chain can transport several parallel rows of coils, for example two, in a horizontal direction.
- the coils loaded with fibrous residues and therefore represented with a hatched surface, are fixed on supports driven by the chain 1, and this in a manner which will be described in more detail below.
- the coils are firstly driven to the left in the drawing, by the lower strand of the chain 1, and after passing around the idler sprocket 4 they are moved to the right of the drawing by the upper strand of the endless chain 1.
- the coils On their supports, the coils have a longitudinal axis 32 which is substantially parallel to the direction of transport.
- the coils to be cleaned 1 then arrive in a cleaning station 5, in the form of a closed cabin, which they pass through continuously, without stopping in this station. In it they are subjected to the action of jets of fluid 6, of preferably water, under a pressure high enough to cut the fibrous residues carried by the coils 2, without damaging the coils themselves.
- jets of fluid 6 come, in the illustrated embodiment, from three nozzles 7 arranged one behind the other in a plane passing through the longitudinal axis of the coils.
- the jets 6 are oriented obliquely towards the incoming coils and they strike the fibrous residues from the top by cutting them approximately along the generatrix of the cylinder, forming the body of the coils, which is located highest in the horizontal position drawn coils.
- nozzles are arranged so as to allow the production of jets having a pressure of between 250 and 320 bars, preferably around 300 bars. It will be readily understood that the pressure of the jets is a function of the type of nozzle used as well as of the adjustment of the pumps supplying the nozzles with liquid.
- the cut fibrous residues then fall by gravity, without hindrance, into a perforated collecting tank 8 (the perforations of which are not shown) in a manner which will be described in more detail below.
- this collecting tank 8 the cut fibers are drained and the water flows through the perforations in the tank 8 in a water collector 9.
- the nozzles 7, three in number are supported on a fixed frame, two cross members 11 and 11 'of which are shown, by means of a hollow section 12.
- the hollow profile is fixed on the crosspieces 11, in a common way, not shown, so that it can be locked on them after pivoting about its axis longitudinal and / or after sliding along the crosspieces 11 and 11 '.
- a support plate 13 is mounted on the hollow profile 12 so as to be able to be locked thereon, commonly, not shown, after longitudinal sliding along the hollow profile 12 as well as possibly a rotation around the axis of this profile.
- the nozzles are supplied with water under high pressure by a flexible supply pipe 14, connected to a distributor 15, which, in the example illustrated, distributes the liquid to three flexible conduits 16 each connected to a nozzle head 17.
- This distributor 15 is fixed to the support plate 13 by angles 18 and 19.
- a support plate 20 for the sprinkler heads is supported by the support plate 13 in a height-adjustable manner, thanks to the presence of vertical buttonholes 21.
- the support plate 13 has holes and the support plate and the support plate can thus be tightened against each other by clamping means, such as bolts and nuts, at a selected height.
- the support plate 20 has a buttonhole 22 which allows, by the same type of fastening, to fix in adjustable manner in height a tab 23 projecting laterally relative to the sprinkler head 17. It is thus possible to adjust the inclination of the sprinklers.
- the relative position of the nozzles with respect to the coils being scrolled can be adjusted in a simple and very precise manner. It is obvious that a number of nozzles other than three could be provided, for example six or more nozzles.
- the cleaning station 5 can also contain spray elements 24, for example two elements of this kind.
- Each spray head 25 is pivotally supported on an angle iron 26, which is itself pivotally supported on the hollow profile.
- the spray head 25 is connected by a flexible conduit to an outlet connector 56 arranged on the hollow profile 12.
- the cavity of the profile 12 is supplied with water by a water inlet 27 and the water under low pressure, d 'about 5 to 6 bars, is brought to the outlet fittings 56, by this cavity.
- the spray elements are used to water the reels whose fibers have been cut, so as to wash the reels, and above all to wet the fibers to make them heavier, which facilitates the sliding of the fibers cut from the reels and their fall by gravity in the collecting tank 8.
- the coils 2 then reach the return sprocket 10 of the endless chain 1, where the coils are then redirected to the left in FIG. 1, by the lower strand of the chain.
- the coils 2, still driven continuously, and now drained, can then be introduced through a drying tunnel 27 where they are swept by a current of air supplied by fans 28.
- the drying air is then taken from the tunnel 27 and filtered in the installation 29, in a manner known per se, before being evacuated to the outside.
- the coils are then discharged at 30, in a manner which will be described in more detail below, in coil collectors 31.
- Figures 3 and 4 there is shown the mode of support of the coils 2 on the endless chain 1, so that their longitudinal axis 32 is parallel to the direction of transport.
- Figure 3 there is illustrated in particular a way of proceeding to obtain a fall by gravity, without hindrance, of the cut fibers, in the cleaning station.
- reel supports 33 each comprising a bar 34 which extends laterally, in cantilever, relative to the chain and which maintains at its end remote from the chain an element of U-shaped pinch, when viewed from above.
- One of the wings 35 of the U is rigid and retains the flange of the coil forwards, the coil being shown in phantom.
- this wing 35 is formed by two elongated upper and lower legs.
- the other wing of the U is formed of a centering disc 36 of frustoconical shape, corresponding to the dimensions of the cavity of the coil.
- This centering disc 36 is connected to the bar 34 by a spring leaf 37 which recalls the flange of the coil towards the front, towards the rigid wing 35 of the U.
- the chain 1 At a distance from the bar 34, towards the front, which corresponds to a length of spool 2, the chain 1 also supports a second bar 38 at the end of which is arranged a V-shaped element 39 open upwards, which supports and centers the front end of the coil 2.
- each bar 34 is provided with a guide bracket 40 which slides on a fixed longitudinal guide 41 of the support frame of the device according to the invention.
- the coils 2 are in the cleaning station, when they have just been subjected to the action of the nozzles 7 and the fibers have been cut. Above the coils, the spray elements 24 already described are arranged.
- guide means for guiding the fall by gravity of the fibers.
- Guide means are deflecting sheets 57 preferably inclined at about 45 °. These sheets, smooth, have the function of distribute without hindrance the glass fibers wetted by the spraying elements in the collecting tank 8 and make it possible to avoid fouling of the reel supports of the lower strand, when they return to the load, and of the chain training.
- reel supports are hingedly mounted on the chain and can be folded down in the retracted position, during the return to the load, allowing the fibers to fall unimpeded, even in l 'absence of deflector plate.
- FIGS. 5 and 6 show the device for ejecting the cleaned coils 2.
- the coils 2 are suspended from the chain 1 by the bar 34 and the clamping elements 33.
- two deflection elements 42 are superimposed, formed by a bar 43 disposed obliquely to the direction of movement of the chain and by a deflection rod 44 supported by this bar 43 so as to come into contact with the periphery of the flange of the coil 2.
- the rod 44 laterally deflects the flange of the coil which consequently slides little by little out of the element of pinching in the form of U 33 and then falls into the collector 31.
- the cleaned coils 2 are evacuated by the collector 31. During this evacuation they are subjected to a manual or optical examination and the coils damaged are separated by the way 45 to a grinder 46, known per se. At the outlet 47 of this grinder 46 on obtains polystyrene fragments that can be reused as raw material by plastic manufacturers.
- the perforated collecting tank 8 When the perforated collecting tank 8 is filled with cut fibers fallen from the reels 2, it can then be transferred, for example by means of rollers, to a drying station 48, for example of the industrial dryer type. There the glass fiber is intensively dried and then transported to a common glass fiber cutter 49, known per se. There, the cut fiber can be harvested in 50 and distributed to users in this form. The cut fiber can be harvested in 50 and distributed to users in this form. The cut fiber can also be conveyed in a carding machine 51 where it is transformed into glass wool which is then harvested at 52 and distributed to users.
- a carding machine 51 where it is transformed into glass wool which is then harvested at 52 and distributed to users.
- the water collected by the collector 9 can advantageously be pumped by any known pump 53 in a filter 54.
- the filtered water can then, by a pump 55, be compressed under high pressure to be reintroduced into the cleaning circuit.
- the method according to the invention thus has, for maximum performance in cutting the fibers carried on the spools, the advantage of recycling almost all of the waste by recovering it at the outlet of the device according to the invention.
- the water consumption amounts to approximately 1 m 3 and the glass fiber is recovered as described above.
