Description
Cette invention concerne un système de verrouillage / déverrouillage rapide d’une barre de convoyeur à lit de clous à la chaîne d’entraînement.This invention relates to a system for quickly locking / unlocking a nail bed conveyor bar at the drive chain.
Les convoyeurs de manutention de bandes ou de feuilles de tôle soumises à une découpe laser sont bien connus.Belt conveyors or sheets of sheet metal subjected to laser cutting are well known.
Un modèle connu de ces convoyeurs est constitué de deux chaînes juxtaposées, dirigées le long de rouleaux, reliées l’une à l’autre par plusieurs barres parallèles disposées avec le plan vertical.A known model of these conveyors consists of two chains juxtaposed, directed along rollers, connected to one another by several parallel bars arranged with the vertical plane.
Ces barres ont, en particulier, une forme principalement en dents de scie afin de former plusieurs points d’appui et de replier leurs extrémités à 90° pour former un appendice. L’appendice présente deux trous dans lesquels peuvent s’engager des vis qui s’engagent à leur tour dans des trous prévus sur une bride en forme de L intégrée au maillon de la chaîne.These bars have, in particular, a form mainly sawtooth to form several points of support and fold their ends to 90 ° to form an appendix. The appendix has two holes in which screws can engage, which in turn engage in holes provided on an L-shaped flange integrated in the chain link.
Cependant, ces barres connues présentent certains inconvénients et notamment : - une perte de temps importante à la fois pour verrouiller la barre à la bride ou pour la désengager de celle-ci, - le besoin d’équipements pour l’engagement / le désengagement des vis de fixation, - la possibilité qu’avec le temps, les vis ne se cassent, empêchant le désengagement de la barre de la bride.However, these known bars have certain drawbacks and in particular: - a significant loss of time both to lock the bar to the flange or to disengage it from the latter, - the need for equipment for the engagement / disengagement of the fastening screw, - the possibility that with time, the screws will break, preventing the disengagement of the bar from the flange.
Le but de l’invention est d’éliminer ces inconvénients et de fournir un système qui permet à la barre d’être simplement et facilement verrouillée / déverrouillée aux chaînes sans nécessiter d’outils.The object of the invention is to eliminate these disadvantages and to provide a system which allows the bar to be simply and easily locked / unlocked to the chains without requiring tools.
Cet objectif est atteint selon l’invention avec un système de verrouillage / déverrouillage rapide d’une barre de convoyeur à lit de clous sur la chaîne d’entraînement, dans lequel ; - la barre du convoyeur est constituée d’une barre verticale 2 présentant au niveau supérieur plusieurs dents 4, chaque extrémité de la barre présentant un trou 6 et un évidement 8 en forme de U retourné et comprenant également : - un bloc 12 pouvant être fixé aux maillons 22 de la chaîne du convoyeur, ce bloc présentant une fente verticale 26 dont une paroi présente un trou horizontal 28 auquel fait face un logement fileté prévu sur l’autre paroi, et dans lequel s’engage un piston 34 dont la tête, en l’absence de contraintes extérieures, est élastiquement maintenue en prise dans le trou 6 de cette barre 2 lorsque celle-ci est insérée dans l’évidement 8 et dans ce trou horizontal 28, - des moyens de désengagement du piston 34 de ces trous.This object is achieved according to the invention with a rapid locking / unlocking system of a nail bed conveyor bar on the drive chain, wherein; the conveyor bar consists of a vertical bar 2 having at the upper level a plurality of teeth 4, each end of the bar having a hole 6 and a recess 8 in the shape of an inverted U and also comprising: a block 12 which can be fixed to the links 22 of the conveyor chain, this block having a vertical slot 26, one wall has a horizontal hole 28 which faces a threaded housing provided on the other wall, and in which engages a piston 34 whose head, in the absence of external constraints, is elastically retained engaged in the hole 6 of the bar 2 when it is inserted into the recess 8 and in this horizontal hole 28, - means for disengaging the piston 34 from these holes .
Cette invention est décrite ci-après plus en détails en référence aux tableaux de schémas joints, dans lesquels : la figure 1 montre une barre de lit de clous dans une vue en perspective interrompue, la figure 2 montre cette barre dans une vue en perspective engagée par le bloc de verrouillage, la figure 3 la montre en condition d’extraction du bloc, la figure 4 montre en coupe le bloc en phase de verrouillage de la barre, et la figure 5 le montre en phase d’extraction de la barre.This invention is hereinafter described in more detail with reference to the accompanying diagrammatic tables, in which: FIG. 1 shows a nail bed bar in an interrupted perspective view, FIG. 2 shows this bar in a perspective perspective view. by the locking block, FIG. 3 shows it in the extraction condition of the block, FIG. 4 shows in section the block in the locking phase of the bar, and FIG. 5 shows it in the extraction phase of the bar.
Comme on le voit sur les figures, le système de verrouillage selon l’invention prévoit que les barres de soutien des plaques / de la bande soient de type à lit de clous, c’est-à-dire constituées d’une barre 2 principalement constituée de plusieurs dents verticales 4 d’appui de la plaque / bande à perforer.As can be seen in the figures, the locking system according to the invention provides that the support bars of the plates / of the strip are of the nail-bed type, that is to say consisting of a bar 2 mainly consisting of several vertical teeth 4 supporting the plate / strip to be punched.
Chaque extrémité de la barre présente un trou 6 et une cavité 8 en forme de U retourné.Each end of the bar has a hole 6 and a U-shaped cavity 8 returned.
La barre 2 présente la bande inférieure 10 en coupe transversale principalement en forme de S, L’invention comprend également un bloc indiqué par le schéma 12 qui présente deux trous 14 dans lesquels peuvent s’engager des vis 16 qui engagent à leur tour l'aile horizontale 18 d’une bride en forme de L 20 fixée au maillon 22 d’un convoyeur à chaîne.The bar 2 has the lower band 10 in cross-section mainly S-shaped. The invention also comprises a block indicated by the diagram 12 which has two holes 14 in which screws 16 can engage, which in turn engage the horizontal flange 18 of an L-shaped flange 20 attached to the link 22 of a chain conveyor.
Le bloc 12 est formé d’un corps parallélépipédique présentant une fente verticale 26 de largeur légèrement supérieure à l’épaisseur de la barre 2, avec une paroi latérale présentant un trou 28.The block 12 is formed of a parallelepipedal body having a vertical slot 26 of width slightly greater than the thickness of the bar 2, with a side wall having a hole 28.
Le système de verrouillage comprend également des moyens de désengagements constitués d’une bague de prise 38.The locking system also comprises disengagement means consisting of a gripping ring 38.
Face au trou 28 est prévu un logement fileté 30 dans lequel s’engage un piston 34 à ressort 36, et réglable par un boulon 32, actionnable par la bague de prise 38.Opposite the hole 28 is a threaded housing 30 in which a spring-loaded piston 34 engages and is adjustable by a bolt 32, operable by the engagement ring 38.
La tête du piston est élastiquement maintenue en prise au moyen de ressort 36.The piston head is resiliently engaged by means of a spring 36.
Le ressort est réglable dans son degré de précharge au moyen du boulon 32.The spring is adjustable in its degree of preload by means of the bolt 32.
En particulier, le piston 34 présente une bande annulaire 40 qui délimite, par une portion annulaire anguiée 42, le logement du ressort 36.In particular, the piston 34 has an annular band 40 which delimits, by an annular annular portion 42, the housing of the spring 36.
Le fonctionnement du système de verrouillage / déverrouillage selon l’invention est le suivant.The operation of the locking / unlocking system according to the invention is as follows.
Dans des conditions normales, l’action élastique du ressort 36 maintient l’extrémité du piston 34 insérée dans le trou 28.Under normal conditions, the elastic action of the spring 36 holds the end of the piston 34 inserted in the hole 28.
Pour fixer la barre, la bague de prise 38 est actionnée afin de dégager l’extrémité du piston 34 du trou 28 par opposition à l’action élastique du ressort 36.To secure the bar, the engagement ring 38 is actuated to disengage the end of the piston 34 from the hole 28 as opposed to the resilient action of the spring 36.
Une fois que la fente 26 est totalement libre, la barre 2 est positionnée à l’intérieur de la fente 24 pour une mise en prise par l’évidement 8.Once the slot 26 is completely free, the bar 2 is positioned inside the slot 24 for engagement by the recess 8.
La prise est donc relâchée sur la bague 38 et la réaction élastique du ressort 36 pousse l’extrémité du piston 34 à s’insérer tout d’abord dans le trou 6 et ensuite dans le trou 28 pour maintenir fermement la barre. D’après ce qui précède, il est clair que l’élément selon l’invention permet à la barre d’être verrouillée / déverrouillée du bloc d’une manière simple et facile.The grip is released on the ring 38 and the elastic reaction of the spring 36 pushes the end of the piston 34 to first insert into the hole 6 and then into the hole 28 to firmly hold the bar. From the foregoing, it is clear that the element according to the invention allows the bar to be locked / unlocked from the block in a simple and easy manner.
