Description

La présente invention concerne la compression des ferrailles en paquets.The present invention relates to the compression of scrap into bundles.

On connaît déjà, dans ce domaine, de nombreuses cisailles dans lesquelles les ferrailles sont comprimées par une presse latérale, avant d'être coupées à la longueur du paquet désiré.Numerous shears are already known in this field in which the scrap is compressed by a lateral press, before being cut to the length of the desired package.

Parmi ces cisailles, certaines permettent, par le jeu de plusieurs pistons ou éléments de piston, de réaliser des paquets de sections différentes. Ces cisailles présentent toutefois, l'inconvénient de nécessiter autant de vérins pousseurs que de pistons ou éléments de pistons utilisés, ce qui complique notablement la construction de la machine, en rend l'entretien plus compliqué et obère le coût, tant de la construction que de l'entretien de ces machines.Among these shears, some allow, by the play of several pistons or piston elements, to produce packets of different sections. However, these shears have the disadvantage of requiring as many push cylinders as pistons or piston elements used, which considerably complicates the construction of the machine, makes its maintenance more complicated and increases the cost, both of construction and maintenance of these machines.

La présente invention a notamment pour but de pallier les inconvénients précédents des cisailles connues permettant la réalisation de paquets de sections différentes.The object of the present invention is in particular to overcome the preceding drawbacks of known shears allowing the production of packages of different sections.

Elle concerne à cet effet une cisaille hydraulique pour ferrailles comprimées en paquets, comprenant une chambre de compression, coopérant avec une presse latérale et dont les dimensions sont sélectivement ajustables pour la réalisation de paquets de sections différentes, des moyens de coupe de ces paquets après leur sortie de la chambre de compression, et des moyens de transfert pour conduire les paquets de l'enceinte de compression aux moyens de coupe, caractérisée en ce qu'elle comprend une pluralité de pistons présentant chacun une section correspondant à celle d'un des paquets à réaliser, un barillet supportant les pistons et permettant par rotation sur lui-même, l'alignement sélectif de chacun d'eux avec la chambre de compression, un vérin pousseur fixe aligné avec la chambre de compression, et des moyens pour la liaison sélective temporaire de la tige dudit vérin avec le piston choisieTo this end, it relates to a hydraulic shear for scrap compressed into bundles, comprising a compression chamber, cooperating with a lateral press and whose dimensions are selectively adjustable for producing bundles of different sections, means for cutting these bundles after their outlet from the compression chamber, and transfer means for driving the packets from the compression enclosure to the cutting means, characterized in that it comprises a plurality of pistons each having a section corresponding to that of one of the packets to realize, a barrel supporting the pistons and allowing by rotation on itself, the selective alignment of each of them with the compression chamber, a fixed fixed push cylinder with the compression chamber, and means for the selective selective connection of the rod of said cylinder with the selected piston

Suivant l'invention, l'ensemble des pistons permettant de réaliser chacun des paquets d'une section déterminée, peuvent être mis en oeuvre par un seul vérin pousseur fixe.According to the invention, the set of pistons making it possible to produce each of the packets of a determined section can be implemented by a single fixed pusher cylinder.

D'après un mode de réalisation de l'invention le barillet porte deux pistons alignables sélectivement avec la chambre de compression et le vérin fixe par un pivotement de 90° du barillet.According to one embodiment of the invention, the barrel carries two pistons selectively alignable with the compression chamber and the fixed jack by a 90 ° pivoting of the barrel.

On peut bien entendu prévoir plus de deux pistons sur le ba- rilleto Il suffit pour cela de prévoir une disposition angulaire en conséquence.It is of course possible to provide more than two pistons on the barillet. It suffices for this to provide an angular arrangement accordingly.

Suivant une caractéristique de l'invention la liaison sélective entre la tige du vérin pousseur et le piston est réalisée par une paire de machoires liées au piston et pénétrant partiellement dans une rainure circulaire ménagée dans la tige du vérin.According to a characteristic of the invention, the selective connection between the rod of the push cylinder and the piston is produced by a pair of jaws linked to the piston and partially penetrating into a circular groove formed in the rod of the cylinder.

L'invention sera mieux comprise à la lecture de la description qui suit et à l'examen des dessins annexés, dans lesquels :

  • - la figure 1 est une vue partielle de face de la cisaille de l'invention, dans la position de fonctionnement du grand piston,
  • - la figure 2 est une vue de gauche de la figure 1,
  • - la figure 3 est une vue partielle de face de la cisaille de l'invention, dans la position de fonctionnement du petit piston,
  • - la figure 4 est une vue de gauche de la figure 3.
The invention will be better understood on reading the following description and on examining the appended drawings, in which:
  • FIG. 1 is a partial front view of the shears of the invention, in the operating position of the large piston,
  • FIG. 2 is a left view of FIG. 1,
  • FIG. 3 is a partial front view of the shears of the invention, in the operating position of the small piston,
  • - Figure 4 is a left view of Figure 3.

La cisaille de l'invention n'est représentée que très partiellement sur les figures 1 à 4, qui n'en montrent schématiquement que la partie située en amont de la caisse de chargement des ferrailles 1 et de la chambre de compression (non représentée). Il y a lieu de rappeler que la cisaille comprend également quoique non représentés :

  • - une presse transversale située en regard de la chambre de compression dans laquelle cette presse comprime les ferrailles admises par la caisse de chargement,
  • - des moyens pour adapter la section de la chambre de compression à celle des paquets à réaliser,
  • - des moyens pour la coupe transversale des paquets à une longueur déterminée.
The shears of the invention are only very represented by tially in Figures 1 to 4, which schematically show only the part located upstream of the scrap loading box 1 and the compression chamber (not shown). It should be recalled that the shears also includes, although not shown:
  • - a transverse press located opposite the compression chamber in which this press compresses the scrap metal admitted by the loading box,
  • means for adapting the section of the compression chamber to that of the packages to be produced,
  • - Means for the cross section of the packages to a determined length.

Suivant l'invention, la cisaille comprend deux vérins 2a, 2b, montés sur un barillet 3 et dont on voit seulement les queues dépassant dudit barillet 3.According to the invention, the shears comprise two jacks 2a, 2b, mounted on a barrel 3 and of which we only see the tails projecting from said barrel 3.

Le barillet 3 est constitué par une structure métallique solidaire d'un axe 4, libre en rotation sur un support fixe 5, par rapport auquel ses pivotements sont commandés par un piston de manoeuvre 6, dont la tige 7 est articulée sur les flasques d'un maneton 9, lié en rotation à l'axe 4.The barrel 3 is constituted by a metallic structure integral with an axis 4, free to rotate on a fixed support 5, with respect to which its pivotings are controlled by an operating piston 6, the rod 7 of which is articulated on the flanges of a crankpin 9, linked in rotation to the axis 4.

Comme montré sur les figures 1 et 2 d'une part, 3 et 4g d'autre part, chaque piston 2 peut être amené sélectivement dans sa position haute (par pivotement du barillet 3, commandé par le piston de manoeuvre 6) dans laquelle il se trouve alors aligné :

  • - d'une part, avec la chambre de compression (non représentée), la section de celle-ci correspondant alors à celle dudit piston en position haute,
  • - d'autre part, avec un vérin pousseur fixe à tige 9.
As shown in FIGS. 1 and 2 on the one hand, 3 and 4g on the other hand, each piston 2 can be brought selectively into its high position (by pivoting of the barrel 3, controlled by the operating piston 6) in which it is then aligned:
  • on the one hand, with the compression chamber (not shown), the section of the latter then corresponding to that of said piston in the high position,
  • - on the other hand, with a fixed push rod 9.

On voit sur les dessins, que dans la position haute de chaque piston 2, la tige 9 du vérin pénètre partiellement dans une douille 10 ménagée dans le piston et est liée à celui-ci par des machoires 11 (figures 2 et 4) pénétrant partiellement dans une rainure circulaire de la tige 9 du vérinoIt can be seen in the drawings that, in the high position of each piston 2, the rod 9 of the jack partially penetrates into a sleeve 10 formed in the piston and is linked to the latter by jaws 11 (FIGS. 2 and 4) partially penetrating a circular groove of the rod 9 of the cylinder

Pour amener en position de travail celui des pistons 2 alors en repos, pour passer par exemple de la position de la figure 2 à celle de la figure 4, il suffit :

  • - de reculer le piston 2a jusqu'à la butée arrière 12,
  • - d'ouvrir les machoires 11a,
  • - de reculer la tige 9 du vérin pousseur,
  • - de pivoter le barillet 3, pour amener le piston 2b en position haute (figure 4),
  • - d'avancer la tige 9 du vérin pousseur pour l'amener dans la douille 10b du piston 2b,
  • - de serrer les machoires 11b.
To bring that of the pistons 2 then into rest position, for example to pass from the position of FIG. 2 to that of FIG. 4, it suffices:
  • - move the piston 2a back to the rear stop 12,
  • - open the jaws 11a,
  • - to push back the rod 9 of the pusher cylinder,
  • - pivot the barrel 3, to bring the piston 2b in the high position (FIG. 4),
  • advancing the rod 9 of the push cylinder to bring it into the socket 10b of the piston 2b,
  • - tighten the jaws 11b.

Le piston 2b est alors prêt à fonctionner.The piston 2b is then ready to operate.

On constate sur les figures, que l'axe de la tige 9 du vérin pousseur n'est pas aligné avec celui des pistons 2a et 2b. Cela est dû au fait que les parois 13 des pistons 2a et 2b sont, de construction, de mêmes dimensions et doivent dans les deux positions se situer à la même place. Pour éviter de faire supporter le décalage à un seul des pistons, on a adopté ici une solution de compromis.It can be seen in the figures that the axis of the rod 9 of the push cylinder is not aligned with that of the pistons 2a and 2b. This is due to the fact that the walls 13 of the pistons 2a and 2b are, of construction, of the same dimensions and must in the two positions be located in the same place. To avoid having to support the offset to only one of the pistons, a compromise solution has been adopted here.

Les dimensions correspondent à celles des paquets usuellement fabriqués : 800 x 600 mm pour le petit piston 2b et 800 x 1 200 mm pour le grand piston 2a. Bien entendu d'autres dimensions désirées peuvent être choisies étant rappelé que les dimensions des pistons doivent correspondre à celles pouvant être données à la chambre de compression et, par suite, aux paquets à réaliser.The dimensions correspond to those of the packages usually produced: 800 x 600 mm for the small piston 2b and 800 x 1,200 mm for the large piston 2a. Of course, other desired dimensions can be chosen, it being recalled that the dimensions of the pistons must correspond to those that can be given to the compression chamber and, consequently, to the packages to be produced.

Bien entendu l'invention couvre également les variantes de réalisation de l'exemple décrit et représenté.Of course, the invention also covers the alternative embodiments of the example described and shown.
