  Appareil de coupe comprenant plusieurs outils à trancher tournants

  
en forme de disques.

  
La présente invention concerne un appareil de coupe

  
comprenant plusieurs outils à trancher tournants en forme de

  
disques qui sont agencés les uns à coté'des autres dans un plan.

  
Les appareils de coupe de ce genre,dans lesquels une

  
série de couteaux,de scies ou d'autres disques à trancher tournants

  
sont agencés les uns à côté des autres dans un plan sur une poutre

  
mobile,conviennent pour couper des matières présentées en plaques

  
ou en nappes. Toutefois, du fait qu'il subsiste toujours entre

  
deux disques à trancher voisins un domaine qui n'est

  
. 

  
 <EMI ID=1.1> 

  
le plan des disques à trancher.

  
Le mouvement longitudinal supplémentaire de l'équipage

  
 <EMI ID=2.1> 

  
duite de la coupe elle-même exige une certaine durée minimale.

  
L'invention a pour but de procurer un appareil de coupe du genre indiqué qui n'exige le mouvement de l'équipage de coupe que dans une direction, de sorte que la construction peut s'en trouver simplifiée et la vitesse de coupe augmentée.

  
Conformément à l'invention, on obtient le résultat voulu en donnant aux outils à trancher tournants en forme de dis-

  
 <EMI ID=3.1> 

  
des mouvements rotatifs opposés synchrones sans qu'ils se touchent.

  
Du fait que dans l'appareil de coupe conforma à l'invention, les domaines de coupe des disques tournants contigus s'intarpénètrent, les domaines intermédiaires qui ne sont pas atteints

  
 <EMI ID=4.1> 

  
sionnement judicieux des outils à trancher en forme d'ailes sui-  vant l'invention rend inutile le mouvement longitudinal de l&#65533;équi-  page de coupe. 

  
Les outils à trancher tournants en forme de disques  peuvent avoir la forme d'une aile à trois ou quatre parties,

  
sinon davantage. Il est toutefois particulièrement avantageux 

  
 <EMI ID=5.1> 

  
 <EMI ID=6.1> 

  
le domaine intermédiaire qui n'est pas atteint peut être maintenu  à un minimum. 

  
 <EMI ID=7.1> 

  
arrière du bord tranchant d'une aile corresponde à la profondeur de coupe avant du bord tranchant de l'aile suivante lorsque la position de coupe est atteinte.

  
L'invention a également pour objet l'utilisation d'un appareil de coupe du type décrit ci-dessus pour couper des nappes de fibres minérales animées d'un mouvement continu, l'appareil de coupe étant monté sur un pont à mouvement de descente qui est

  
 <EMI ID=8.1> 

  
passage d'une longueur de nappe choisie au préalable, accompagne d'un mouvement synchrone la nappe de fibres minérales et revient à sa position de départ après l'exécution de la coupe.

  
L'invention est davantage illustrée par un exemple d'exécution préféré pour l'application à la coupe d'une plaque de fibres minérales, donné avec référence aux dessins annexés. Dans les dessins, Fig. 1 est une vue d'ensemble d'un appareil de coupe convenant pour couper transversalement une plaque de fibres minérales; Fig. 2 est une vue en plan et partiellement en coupe <EMI ID=9.1>  Fig. 3 est une vue en détail d'un outil à trancher.

  
Les dessins représentent l'équipage de coupe en agence- 

  
 <EMI ID=10.1> 

  
 <EMI ID=11.1>  

  
processus de coupe proprement dit. En variante, l'équipage de coupe peut avantageusement être monté sur un pont

  
qui accompagne d'un mouvement synchrone la matière à couper, de sorte que le processus de coupe peut être exécuté sans interruption de la fabrication continue de la matière à couper. De tels appareils de coupe accompagnant d'un mouvement synchrone la matière à couper sont connus comme tels (cisailles volantes et scies volantes) et la présente description ne concerne donc pas la construction de tels ponts qui accompagnent d'un mouvement synchrone la matière à couper.

  
La plaque de fibres minérales 1 à couper défile

  
sur un transporteur à rouleaux et repose,au voisinage de l'endroit où la coupe est effectuée, sur la contre-plaque 3 qui est interrompue à l'endroit où les outils à trancher tournants descendent. Les rouleaux de transport 5 du transporteur à rouleaux reposent, tout comme la contre-plaque 3, sur un châssis 6.

  
Le châssis 6 porte également les colonnes verticales 7 sur lesquelles sont montés les guides lisses verticaux 8 au-dessus du plan de transport du transporteur à rouleaux. Le pont

  
de coupe proprement dit, qui est constitué par la poutre porteuse 9 soutenant les outils à trancher et par le cadre 10,

  
 <EMI ID=12.1> 

  
par l'intermédiaire des paliers lisses 12 sur les guides 8. En vue de l'exécution d'une coupe, le pont de coupe est rapidement

  
 <EMI ID=13.1> 

  
est ensuite ramené à sa position initiale.

  
Le mouvement est communiqué aux outils à trancher tournants 18 par un moteur électrique que porte la poutre 9.

  
Les arbres à cardan 20 et les engrenages coniques 21 communiquent aux arbres 22 portant les outils à trancher les mouvements rotatifs opposés synchrones. 

  
Les outils à trancher 18 ont la forme d'ailes en 8 et

  
 <EMI ID=14.1> 

  
22, de manière que les ailes s'engagent dans l'espace libre ménagé par leurs voisines. Pour la coupe de nappes et de plaques

  
de fibres minérales, un tel outil à trancher est avantageusement

  
fait d'acier à haute résistance et est muni de dents 26 à la manière d'une scie circulaire dans la partie 25 de son contour qui effectue la coupe. En variante, l'outil à trancher peut

  
aussi être fait de toute autre matière appropriée et peut être,

  
par exemple, garni de particules de diamant sur son contour effectuant la coupe. On peut observer en particulier à la Fig. 3

  
qu'une aile tranchante diffère d'un secteur de cercle du

  
fait que la distance de la dent 26 au centre de l'outil

  
à trancher est plus faible au bord d'attaque 27 de l'aile que la.distance de la dent 26 au centre de l'outil à trancher au bord

  
de fuite 28 ,de l'aile, de sorte que l'écart de Italie par rapport

  
à la forme circulaire prend la valeur d. La valeur d de l'écart choisie est telle que, pour une vitesse verticale déterminée de l'équipage de coupe et pour une vitesse de rotation déterminée des organes à trancher, la profondeur de coupe des dents 26 au bord de fuite 28 corresponde à la profondeur de coupe des dents au bord d'attaque 27 de l'aile suivante.

  
Lorsqu'on effet l'aile suivante se trouve en position de coupe, l'équipage de coupe se trouve déjà descendu de la valeur d  de sorte que l'écart assure une coupe régulière.



  Cutting device comprising several rotating cutting tools

  
in the form of discs.

  
The present invention relates to a cutting apparatus

  
comprising several rotating cutting tools in the shape of a

  
disks which are arranged next to each other in a plane.

  
Cutting devices of this kind, in which a

  
series of rotating knives, saws or other cutting discs

  
are arranged next to each other in a plane on a beam

  
mobile, suitable for cutting materials presented in sheets

  
or in tablecloths. However, since there is always between

  
two neighboring slicing discs a domain which is

  
.

  
 <EMI ID = 1.1>

  
the plane of the discs to be sliced.

  
The additional longitudinal movement of the crew

  
 <EMI ID = 2.1>

  
picking of the cut itself requires a certain minimum time.

  
It is an object of the invention to provide a cutting apparatus of the kind indicated which requires the movement of the cutting crew only in one direction, so that the construction can be simplified and the cutting speed increased.

  
In accordance with the invention, the desired result is obtained by giving the rotating disc-shaped cutting tools

  
 <EMI ID = 3.1>

  
synchronous opposing rotary movements without them touching.

  
Due to the fact that in the cutting apparatus according to the invention, the cutting areas of the contiguous rotating discs overlap, the intermediate areas which are not reached

  
 <EMI ID = 4.1>

  
The judicious use of the wing-shaped cutting tools according to the invention eliminates the need for longitudinal movement of the cutting equipment.

  
The rotating disc-shaped slicing tools may be in the shape of a three or four part wing,

  
if not more. It is however particularly advantageous

  
 <EMI ID = 5.1>

  
 <EMI ID = 6.1>

  
the intermediate range which is not reached can be kept to a minimum.

  
 <EMI ID = 7.1>

  
back of the cutting edge of one wing is the forward cutting depth of the cutting edge of the next wing when the cutting position is reached.

  
The invention also relates to the use of a cutting apparatus of the type described above for cutting layers of mineral fibers animated by a continuous movement, the cutting apparatus being mounted on a bridge with a downward movement. who is

  
 <EMI ID = 8.1>

  
passage of a previously chosen length of sheet, accompanies the sheet of mineral fibers with a synchronous movement and returns to its starting position after the execution of the cut.

  
The invention is further illustrated by a preferred embodiment for the application to the section of a plate of mineral fibers, given with reference to the accompanying drawings. In the drawings, Fig. 1 is a general view of a cutting apparatus suitable for transversely cutting a plate of mineral fibers; Fig. 2 is a plan view and partially in section <EMI ID = 9.1> FIG. 3 is a detailed view of a slicing tool.

  
The drawings represent the cutting crew in agency-

  
 <EMI ID = 10.1>

  
 <EMI ID = 11.1>

  
actual cutting process. Alternatively, the cutting crew can advantageously be mounted on a bridge

  
which synchronously accompanies the material to be cut, so that the cutting process can be carried out without interrupting the continuous production of the material to be cut. Such cutting devices accompanying the material to be cut with a synchronous movement are known as such (flying shears and flying saws) and the present description therefore does not relate to the construction of such bridges which accompany the material to be cut with a synchronous movement. .

  
The mineral fiber plate 1 to be cut scrolls

  
on a roller conveyor and rests, in the vicinity of the place where the cut is made, on the backing plate 3 which is interrupted at the place where the rotating cutting tools descend. The transport rollers 5 of the roller conveyor rest, like the backing plate 3, on a frame 6.

  
The frame 6 also carries the vertical columns 7 on which the vertical smooth guides 8 are mounted above the transport plane of the roller conveyor. The bridge

  
actual cutting, which is formed by the supporting beam 9 supporting the cutting tools and by the frame 10,

  
 <EMI ID = 12.1>

  
by means of the plain bearings 12 on the guides 8. In order to perform a cut, the cutting bridge is quickly

  
 <EMI ID = 13.1>

  
is then returned to its original position.

  
The movement is communicated to the rotating cutting tools 18 by an electric motor carried by the beam 9.

  
The cardan shafts 20 and the bevel gears 21 communicate to the shafts 22 carrying the cutting tools the opposing synchronous rotary movements.

  
The slicing tools 18 have the shape of 8 wings and

  
 <EMI ID = 14.1>

  
22, so that the wings engage in the free space provided by their neighbors. For cutting tablecloths and plates

  
of mineral fibers, such a slicing tool is advantageously

  
made of high strength steel and is provided with teeth 26 in the manner of a circular saw in the part 25 of its contour which performs the cut. Alternatively, the slicing tool can

  
also be made of any other suitable material and may be,

  
for example, trimmed with diamond particles on its contour making the cut. It can be observed in particular in FIG. 3

  
that a sharp wing differs from a sector of a circle of the

  
causes the distance from tooth 26 to the center of the tool

  
cutting edge is smaller at the leading edge 27 of the wing than the distance from tooth 26 to the center of the cutting tool at the edge

  
trailing 28, of the wing, so that the deviation of Italy from

  
to the circular shape takes the value d. The value d of the difference chosen is such that, for a determined vertical speed of the cutting crew and for a determined speed of rotation of the organs to be sliced, the cutting depth of the teeth 26 at the trailing edge 28 corresponds to the cutting depth of the teeth at the leading edge 27 of the following wing.

  
When the next kite is in the cutting position, the cutting crew is already lowered by the value d so that the gap ensures a regular cut.
