- a fragmentation device is suitable for fragmenting the glass of a used window in that it allows the glass and the frame of this window to be separated, for recycling.
- the fragmentation of the glass indicates the action of breaking, breaking into pieces, crushing, breaking of the glass of a window, in order to separate it from its frame and thus to be able to recycle it.
- a conveyor is a mechanical device suitable for transporting a used window from one end to the other of the device. Such a conveyor can preferably be a belt or a corridor.
- a chain is a series of metal rings engaged in each other.
- a drum designates a wooden or iron cylinder on which this chain is wound. This drum is suitable for carrying out revolutions, that is to say circular movements carried out around an axis of revolution.
- the verb "to bind" must be interpreted in its mechanical sense, and can alternatively refer to a direct or indirect link.
- the drum of a fragmentation assembly is rotated, preferably by a motor, around an axis of revolution transverse to the longitudinal axis of the conveyor or in other words, to its direction of advance.
- At each revolution of the drum at least one percussion head is first brought overhanging the conveyor for thereafter colliding with the conveyor belt, under the effect of gravity.
- said striker assembly is linked to said drum by a plurality of anchoring points, preferably aligned along a transverse axis.
- the multiplication of anchor points makes it possible to distribute the weight of the striker assembly and of the chain between each of the anchor points, and thus to reduce their respective stress.
- said striker assembly is linked to said drum by a plurality of chains, preferably parallel to each other.
- the multiplication of the number of chains makes it possible to distribute the weight of the striker assembly between them, and thus to reduce their respective stress.
- the implementation of a plurality of chains also makes it possible to facilitate the balancing of the striker assembly, in particular during the fragmentation step.
- said striker assembly comprises a plurality of percussion heads aligned in a transverse direction.
- said striker assembly comprises at least one transverse ballast bar.
- ballast crossbar increases the impact force of the striker assembly.
- said transverse bar links a plurality of percussion heads to one another.
- each percussion head is linked to the drum by a respective chain.
- At least one percussion head is linked to said drum via said transverse bar.
- said striker assembly is linked to said drum by M chains, preferably parallel to each other, in that said striker assembly comprises N percussion heads, and in that N is strictly greater than M.
- the assembly formed by said chain and the striker assembly has a length less than or equal to the distance, inscribed along a theoretical vertical axis tangent to the rear of the drum, which separates the rear of the drum of the conveyor.
- the front and rear of the device are defined along the longitudinal axis of the conveyor, the conveyor belt being adapted to transport a used window from the rear to the front of the device.
- the use of a chain with a length less than or equal to this distance D prevents the chain from stays too long on the conveyor belt, in particular to limit the abrasion of the fragmentation heads by the crushed glass present on the conveyor belt.
- the fragmentation device comprises a plurality of striker assemblies linked respectively to the drum by at least one chain.
- said conveyor comprises a mat, preferably ribbed, said drum and the drive means of said mat being adapted to be rotated in opposite directions.
- the invention also relates to a method of fragmenting the glass of a window, characterized in that it implements a fragmentation device suitable for fragmenting the glass of a used window, and comprising at least:
- a fragmentation assembly which surmounts the conveyor and is adapted to fragment the glass of said window during its transport on said conveyor, the fragmentation assembly comprising a drum arranged above said conveyor along an axis of revolution transverse to said longitudinal axis , said drum being linked by at least one chain to a striker assembly comprising at least one percussion head adapted to strike said conveyor at each revolution of said drum.
- said drum and the drive means of said conveyor are rotated in opposite directions.
- the ratio between the speed of advance of the conveyor belt and the speed of revolution of the drum is chosen so that said window is, during its flat transport on said conveyor, struck by said fragmentation assembly at least twice, preferably at least three times, preferably at least four times, preferably at least five times.
- the increase in the frequency of percussion makes it possible to reduce the size of the broken glass, and therefore to facilitate their sorting and / or their subsequent recycling.
- the fragmentation method comprises a subsequent step of separate collection of the fragmented glass on the one hand, and of the frame of said window on the other hand.
- the glass and the frame are of different composition, their separate collection, for example in separate receptacles or bins, makes it possible to facilitate recycling.
- the invention also relates to the fragmented glass obtained via such a fragmentation process.
- FIG. 1 is a schematic sectional view of a fragmentation assembly known from the state of the art
- Figure 2 is a schematic sectional view of a fragmentation device according to a particular embodiment of the invention.
- Figures 3 and 4 are perspective views taken from the rear of the fragmentation assembly which surmounts the conveyor of a fragmentation device according to a particular embodiment of the invention.
- a fragmentation device 1 is suitable for fragmenting the glass of a used window 2, and comprises: A conveyor 3 adapted for the flat transport of the window 2 along a longitudinal axis L, and
- a fragmentation assembly 4 which surmounts the conveyor 3 and is adapted to fragment the glass of the window 2 during its transport on the conveyor 3.
- the fragmentation assembly 4 comprises a drum 5 arranged above the conveyor 3 along an axis of revolution R transverse to the longitudinal axis L.
- the drum 5 is linked to two striker assemblies (7 1 , 7 2 ) by two groups of chains 6ay, each striker assembly 7 1 comprising a plurality of percussion heads (7al, 7a2, ..., 7az) adapted to strike the conveyor 3 at each revolution of the drum 5.
- FIG. 2 is a schematic sectional view taken along a plane perpendicular to this transverse direction, only a chain 6ay and a percussion head 7az are represented by striker assembly 7.
- the fragmentation assembly 4 may comprise only one or, on the contrary, more than two striker assemblies 7, each striker assembly 7 may include one or more percussion heads 7az.
- a used window 2 is first loaded on the conveyor belt 3a, behind the device 1. This used window 2 is then conveyed by the conveyor 3 at the level of the fragmentation assembly 4, c ' that is to say approximately below the drum 5.
- This drum 5 is rotated, preferably by a motor, about an axis of revolution R transverse to the longitudinal axis L of the conveyor 3 or in other words, to his direction of advancement. This direction of advance is shown in Figure 2 by a dotted directional arrow.
- the drum 5 and the conveyor drive means 3 are rotated in opposite directions, each of these directions being represented by dotted directional arrows.
- at each revolution of the drum 5 at least one percussion head 7az is first brought overhanging the conveyor 3 in order subsequently to strike the conveyor belt 3a, under the effect of its weight.
- the glass 2a of the used window 2 is thus separated from its frame 2b, with a view to future sorting / recycling.
- the assembly formed by the chain 6ay and the striker assembly 7 1 has a length equal to the distance D, registered along a theoretical vertical axis tangent to the rear of the drum 5, which separates the rear of the conveyor drum 5 3. This prevents the chain 6ay from remaining too long on the conveyor belt 3a, in particular in order to limit the abrasion of the fragmentation heads 7az by the crushed glass present on the conveyor belt conveyor.
- this chain 6ay makes it possible to reduce the mechanical stresses exerted at the anchoring points 5ax of the chain 6ay with the drum 5 on the one hand, and with the striker assembly 7 on the other hand.
- such a chain 6ay does not provide any obstacle to the vertical acceleration of each percussion head 7az, at the time of their fall, which makes it possible to maximize the impact force of this head on the glass 8b of the used window. 2, and therefore to obtain a satisfactory fragmentation of this glass 8b.
- the ratio between the speed of advance of the conveyor belt 3 and the speed of revolution of the drum 5 is chosen so that the window 2 is, during its flat transport on said conveyor 3, struck by a set of fragmentation 4 at least five times.
- Figures 3 and 4 are perspective views taken from the rear of the fragmentation assembly 4 which overcomes the conveyor 3 of a fragmentation device 1 according to a particular embodiment of the invention.
- This fragmentation assembly 4 comprises three striker assemblies (7 1 , 7 2 , 7 3 ).
- Each striker assembly (7 1 , 7 2 , 7 3 ) comprises a plurality of percussion heads (7al, 7a2, ..., 7az) which are linked to the drum 5 via a plurality of anchoring points (5al, 5a2, ..., 5ax).
- the percussion heads (7al, 7a2, ..., 7az) and anchor points (5al, 5a2, ..., 5ax) are aligned along respective transverse axes (Rz, Rx).
- the percussion heads (7al, 7a2, ..., 7az) and the chains (6al, 6a2, ..., 6ay) are linked together by a transverse bar 8 of ballasting.
- each of the striker assemblies (7 1 , 7 2 , 7 3 ) shown in Figures 3 and 4 is linked to the drum 5 by four chains (6al, 6a2, ..., 6ay), and includes seven percussion heads (7al, 7a2, ..., 7az), one head in two thus being linked to the drum 5 by intermediate of the crossbar 8.
- the number of points of impact with the glass is therefore considerably increased, regardless of the number of chains used.
