Description

La présente invention a pour objet un palisson, c'est-à-dire une machine de tannerie comprenant deux plaques pourvues de dents et disposées l'une au-dessus de l'autre, lesquelles plaques se rapprochent ou s'éloignent alternativement l'une de l'autre.The present invention relates to a palisson, that is to say a tanning machine comprising two plates provided with teeth and arranged one above the other, which plates alternately approach or move away from it. one of the other.

Les palissons sont utilisés à la fin de l'opération de séchage dans le but de tirer la peau dans toutes les directions avec des sollicitations violentes, de façon à ce que ladite peau puisse reprendre de la souples- se et du moelleux.Pallids are used at the end of the drying operation with the aim of pulling the skin in all directions with violent stresses, so that said skin can regain flexibility and softness.

En vis-à-vis de chacune des dents de l'une des plaques, l'autre plaque comporte une creusure à l'intérieur de laquelle pénètre la dent susvisée au cours de la phase durant laquelle les deux plaques sont le plus rap­prochées.Opposite each of the teeth of one of the plates, the other plate has a recess inside which the abovementioned tooth penetrates during the phase during which the two plates are closest together.

De cette manière les fibres durcies de la peau qui au terme de l'opéra­tion de séchage sont collées les unes aux autres sont aptes à s'étendre à nouveau, en conférant ainsi à ladite peau les caractéristiques souhai­tées de souplesse et de moelleux.In this way the hardened fibers of the skin which at the end of the drying operation are bonded to each other are capable of spreading again, thus giving said skin the desired characteristics of suppleness and softness.

Dans l'état actuel de la technique, l'une des deux plaques est fixe en étant rendue solidaire de la structure de la machine, tandis qu'à l'autre est assigné le rôle d'effectuer l'intégralité de la course alternative.In the current state of the art, one of the two plates is fixed by being made integral with the structure of the machine, while the other is assigned the role of performing the entire alternative race.

Le système le plus souvent utilisé pour assurer le déplacement de la plaque mobile est formé par un dispositif du type bielle-manivelle agen­cé au niveau de l'un des deux bords de ladite plaque.The system most often used to move the movable plate is formed by a rod-crank type device arranged at one of the two edges of said plate.

Un tel dispositif présente le grave inconvénient de nécessiter des biel­les très robustes, de grandes dimensions, puisqu'il est indispensable que la plaque mobile soit appliquée contre la plaque fixe avec une forte pression ; d'où l'obligation de devoir déplacer des masses considérables qui sont difficilement susceptibles d'être équilibrées, de sorte que la vitesse de travail est nécessairement limitée, ce qui nuit à la produc­tivité de la machine elle-même.Such a device has the serious drawback of requiring very robust connecting rods, of large dimensions, since it is essential that the movable plate be applied against the fixed plate with high pressure; hence the obligation to have to move considerable masses which are difficult to balance, so that the working speed is necessarily limited, which affects the productivity of the machine itself.

La présente invention se propose de réaliser un palisson équipé d'un système d'animation grâce auquel il est possible de dépasser les limita­ tions des dispositifs de type connu.The present invention proposes to produce a pallet equipped with an animation system thanks to which it is possible to exceed the limits tions of known type devices.

Le palisson suivant l'invention est défini à la revendication 1.The pallet according to the invention is defined in claim 1.

En fait, suivant l'invention le déplacement de la plaque inférieure du palisson est obtenu à l'aide d'une ou de plusieurs paires de tiges orientées de manière substantiellement verticale, qui, au niveau de leurs extrémités opposées sont respectivement articulées à l'embase de la machine et à la plaque mobile et qui au niveau de leurs autres extrémités mises en contact réciproque, sont elles-mêmes articulées l'une à l'autre. La plaque mobile est guidée de façon à ce que ses mouvements puissent s'effectuer alternativement vers le haut et vers le bas.In fact, according to the invention the displacement of the bottom plate of the palisson is obtained using one or more pairs of rods oriented substantially vertically, which, at their opposite ends are respectively articulated to the base of the machine and to the movable plate and which at their other ends brought into reciprocal contact, are themselves articulated to each other. The movable plate is guided so that its movements can be carried out alternately upwards and downwards.

Ces mouvements sont obtenus à l'aide de moyens propres à déterminer le déplacement alternatif des charnières qui opèrent la liaison entre les deux tiges d'une même paire.These movements are obtained using means specific to determining the alternating displacement of the hinges which operate the connection between the two rods of the same pair.

De manière avantageuse on prévoit, non pas une seule paire de tiges, mais bien une série de telles paires disposées à la façon ci-dessus dé­crite, entre l'embase de la machine et la plaque inférieure, lesdites paires étant mutuellement reliées par un bras auquel est incorporée la charnière d'assemblage des tiges d'une même paire, si bien qu'il est nécessaire et suffisant de faire en sorte que le bras sus-mentionné soit animé d'un mouvement alternatif pour assurer les déplacements désirés de la plaque inférieure.Advantageously, there is provided, not a single pair of rods, but a series of such pairs arranged in the manner described above, between the base of the machine and the bottom plate, said pairs being mutually connected by an arm which is incorporated the hinge for assembling rods of the same pair, so that it is necessary and sufficient to ensure that the above-mentioned arm is driven in an alternating movement to ensure the desired displacements of the plate lower.

Conformément à une forme préférée de réalisation de l'invention, les paires de tiges sont disposées suivant deux groupes distincts, chacun de ceux-ci comprenant l'un des bras sus-indiqués et étant placé en position latérale par rapport à deux éléments excentriques, prévus au niveau de la partie centrale de la machine et à chacun desquels est articulé un bras auxiliaire lui-même articulé par son extrémité opposée à l'un des bras précités.In accordance with a preferred embodiment of the invention, the pairs of rods are arranged in two distinct groups, each of these comprising one of the arms indicated above and being placed in lateral position relative to two eccentric elements, provided at the central part of the machine and to each of which is articulated an auxiliary arm itself articulated by its end opposite to one of the aforementioned arms.

Le mouvement des éléments excentriques détermine la translation horizon­tale des bras, ce qui provoque le rapprochement et l'écartement alterna­tifs des bras et engendre donc l'inclinaison des tiges par rapport à la verticale et, en dernière analyse, l'abaissement et l'élévation alternés de la plaque inférieure.The movement of the eccentric elements determines the horizontal translation of the arms, which causes the arms to approach and move apart alternately and therefore generates the inclination of the rods relative to the vertical and, in the final analysis, the lowering and the raising alternate of the bottom plate.

Le dispositif suivant l'invention permet d'obtenir de manière très sim­ple l'équilibrage des masses en mouvement, si bien que la vitesse de travail de la machine peut se révéler beaucoup plus élevée que celle susceptible d'être obtenue avec les dispositifs classiques.The device according to the invention allows very simple balancing of the moving masses, so that the working speed of the machine can turn out to be much higher than that which can be obtained with conventional devices.

De plus, grâce à l'invention il est possible de travailler les peaux avec une vitesse d'aplatissement également plus élevée que ce qu'il est possible d'atteindre avec les dispositifs de type connu, de sorte qu'on est en mesure de réaliser un meilleur élargissement des peaux, avec tous les avantages économiques en résultant pour l'utilisateur du fait que les peaux sont, comme on le sait, vendues à la surface et non au poids.In addition, thanks to the invention it is possible to work the skins with a flattening speed also higher than what it is possible to achieve with the devices of known type, so that one is able to achieve a better enlargement of the skins, with all the economic advantages resulting for the user from the fact that the skins are, as is known, sold on the surface and not by weight.

Les caractéristiques qui précèdent ainsi que d'autres vont maintenant être décrites en détail en se référant à certaines formes particulières de réalisation de l'invention, données à titre d'exemple non limitatif, avec l'aide du dessin annexé, dans lequel :

  • Les fig. 1 et 2 représentent les deux plaques du palisson à deux positions différentes de travail.
  • Les fig. 3 à 5 montrent de manière schématique le palisson suivant l'in­vention à trois autres phases de travail.
  • Les fig. 6 à 9 sont des vues schématiques d'une forme particulière de réalisation de l'invention, représentée à certaines phases successives du processus opératoire.
The foregoing characteristics as well as others will now be described in detail with reference to certain particular embodiments of the invention, given by way of nonlimiting example, with the aid of the appended drawing, in which:
  • Figs. 1 and 2 show the two palisson plates at two different working positions.
  • Figs. 3 to 5 show schematically the tackle according to the invention in three other working phases.
  • Figs. 6 to 9 are schematic views of a particular embodiment of the invention, shown in certain successive phases of the operating process.

En fig. 1 et 2 on peut voir que le palisson comporte une plaque supé­rieure 1 superposée à une plaque inférieure 2, ces deux plaques présen­tant en correspondance sur leurs faces en vis-à-vis des dents 3 aux­quelles correspondent sur la plaque opposée des cavités 4.In fig. 1 and 2 it can be seen that the palisson comprises an upper plate 1 superimposed on a lower plate 2, these two plates having in correspondence on their faces opposite the teeth 3 to which correspond on the opposite plate cavities 4.

La peau destinée à passer dans l'espace compris entre les deux pla­ques et est alors soumise à une action de mise sous tension exercée par les dents 3 desdites plaques.The skin intended to pass into the space between the two plates and is then subjected to a tensioning action exerted by the teeth 3 of said plates.

Conformément à l'invention la plaque supérieure 1 est fixe en étant rendue solidaire de la structure-support 10 de la machine, tandis que la plaque inférieure 2 est mobile. Le déplacement de cette plaque inférieu­re est obtenu au moyen d'une ou plusieurs paires de tiges 5′ et 5˝, orientées de manière substantiellement verticale au-dessous de ladite plaque.According to the invention the upper plate 1 is fixed by being made integral with the support structure 10 of the machine, while the lower plate 2 is movable. The displacement of this lower plate is obtained by means of one or more pairs of rods 5 ′ and 5˝, oriented substantially vertically below said plate.

La tige inférieure 5˝ est articulée en 6 à la structure fixe 10 de la machine, ainsi qu'en 7 à l'extrémité inférieure de la tige supérieure 5′ . Cette dernière est elle-même articulée en 8 par son extrémité oppo­sée à la plaque inférieure 2.The lower rod 5˝ is articulated at 6 to the fixed structure 10 of the machine, as well as at 7 at the lower end of the upper rod 5 ′. The latter is itself articulated at 8 by its end opposite to the lower plate 2.

Latéralement par rapport à la plaque inférieure 2 est prévu un support de guidage 9, solidaire de la structure 10 de la machine et propre à ne permettre à ladite plaque inférieure qu'un mouvement alternatif orienté verticalement.Laterally relative to the lower plate 2 is provided a guide support 9, integral with the structure 10 of the machine and suitable for allowing said lower plate only a reciprocating movement oriented vertically.

Dans le cas où comme représenté on prévoit plus d'une paire de tiges, ces paires seront réunies les unes aux autres par un bras 11 orienté horizontalement pour supporter les charnières 7.In the case where, as shown, more than one pair of rods is provided, these pairs will be joined to each other by an arm 11 oriented horizontally to support the hinges 7.

En pareil cas la condition fondamentale pour le fonctionnement du dis­positif réside dans le fait que les tiges supérieures, comme les tiges inférieures, doivent être disposées parallèlement.In such a case, the fundamental condition for the operation of the device lies in the fact that the upper rods, like the lower rods, must be arranged in parallel.

La caractéristique essentielle de l'invention est constituée par le fait que les tiges inférieures 5˝ sont contraintes à accomplir un mouvement alternatif centré sur la charnière 6, de façon à ce que la charnière 7 parcourre un bref arc de cercle.The essential characteristic of the invention consists in the fact that the lower rods 5˝ are forced to perform an alternating movement centered on the hinge 6, so that the hinge 7 travels a short arc.

En se référant aux fig. 3 à 5 on peut voir que si la charnière est dé­placée de la position de gauche à la position centrale, elle doit néces­sairement se soulever en déterminant l'élévation de la plaque inférieure 2 et en conséquence l'aplatissement de la peau. En sens inverse, lorsque la tige inférieure 5˝ se déplace vers la droite, la charnière 7 s'abais­se en provoque la descente de la plaque inférieure 2.Referring to fig. 3 to 5 it can be seen that if the hinge is moved from the left position to the central position, it must necessarily be raised by determining the elevation of the bottom plate 2 and consequently the flattening of the skin. Conversely, when the lower rod 5˝ moves to the right, the hinge 7 lowers, causing the lower plate 2 to descend.

La présence du bras 11, dans la cas où on a prévu plus d'une paire de tiges, est indispensable pour garantir la concordance des phases entre les différentes paires de tiges, ainsi que pour permettre la mise en mouvement au moyen d'un dispositif unique.The presence of the arm 11, in the case where more than one pair of rods has been provided, is essential to guarantee the concordance of the phases between the different pairs of rods, as well as to allow the setting in movement by means of a single device.

Un système efficace de mise en mouvement des tiges est illustré en fig. 6 à 9.An effective system for moving the rods is illustrated in fig. 6 to 9.

Sur ces figures on peut voir que les différentes tiges 5′ et 5˝ sont sybdivisées en deux groupes, dans chacun desquels est prévu un bras 11 auquel sont incorporées les différentes charnières 7 qui relient les tiges d'une même paire.In these figures it can be seen that the different rods 5 ′ and 5˝ are divided into two groups, in each of which is provided an arm 11 in which are incorporated the different hinges 7 which connect the rods of the same pair.

Au niveau du centre de la machine est placé un volant 12 sur lequel s'articulent en 13, de manière symétrique par rapport à l'axe dudit vo­lant, deux bras auxiliaires 14 dont les extrémités opposées s'articulent en 15 aux bras 11.At the center of the machine, a flywheel 12 is placed on which articulate at 13, symmetrically with respect to the axis of said flywheel, two auxiliary arms 14 whose opposite ends articulate at 15 at arms 11.

On comprend sans peine que la rotation du volant 12, qui peut être assurée par tout moyen connu (par exemple à l'aide d'un moto-réducteur ou d'un système à bielle), détermine, à partir de la position illustrée en fig. 6, tout d'abord le soulèvement de la plaque inférieure 2, puis son abaissement et enfin à nouveau son soulèvement.It is easy to understand that the rotation of the flywheel 12, which can be ensured by any known means (for example using a geared motor or a connecting rod system), determines, from the position illustrated in fig. 6, firstly raising the lower plate 2, then lowering it and finally raising it again.

Sur les figures on voit que la position d'abaissement maximal de la pla­que mobile 2 correspond à la situation dans laquelle les deux bras auxi­liaires 14 sont disposés en alignement, tandis que celle d'élévation maximale correspond à la situation dans laquelle les bras auxiliaires 14 sont le plus écartés l'un de l'autre.In the figures we see that the maximum lowering position of the movable plate 2 corresponds to the situation in which the two auxiliary arms 14 are arranged in alignment, while that of maximum elevation corresponds to the situation in which the auxiliary arms 14 are furthest apart from each other.

En utilisant cette forme particulière de réalisation, il est possible de prévoir un grand nombre de tiges 5′ et 5˝ de petites dimensions et on est en outre en mesure d'obtenir un degré élevé d'équilibre dynamique des moments qui agissent sur le volant 12 et sur les moyens qui le met­tent en rotation, avec un avantage important du point de vue constructif comme de celui de l'utilisation puisqu'on obtient un bas niveau de vi­brations.By using this particular embodiment, it is possible to provide a large number of rods 5 ′ and 5˝ of small dimensions and it is also possible to obtain a high degree of dynamic balance of the moments which act on the steering wheel. 12 and on the means which set it in rotation, with an important advantage from the constructive point of view as well as that of use since a low level of vibration is obtained.

En vue d'augmenter l'effort de compression de la plaque mobile 2 contre la plaque fixe 1 on peut prévoir des moyens de poussée consistant, par exemple, en des dispositifs élastiques 16 (fig. 3, 4 et 5) ou en des vérins pneumatiques ou hydrauliques qui exercent leur effort contre la face inférieure de la plaque inférieure 2. Ceci permet de réduire la puissance du moteur nécessaire au fonctionnement du palisson, et d'augmenter de manière considérable la cadence maximale de travail susceptible d'être obtenue avec le dispositif suivant l'invention.In order to increase the compression force of the movable plate 2 against the fixed plate 1, it is possible to provide thrust means consisting, for example, of elastic devices 16 (fig. 3, 4 and 5) or of jacks pneumatic or hydraulic which exert their force against the lower face of the lower plate 2. This makes it possible to reduce the power of the motor necessary for the operation of the tackle, and to considerably increase the maximum rate of work likely to be obtained with the device according to the invention.
