Removal device for use in splitting machines for hides, characterised in that it comprises a wedge (1) disposed immediately downstream of the machine (11) to lift the hair side of the hide as far as a conveyor line (2) which removes it from said machine with the aid of series of free-running toothed drums (12, 13) suitable for keeping the hides pressed against the aforesaid line and conveying them to a receptacle (6), thereby enabling automation of the operations of stacking the hides in said receptacle.

Description

La présente invention a pour objet un dispositif d'évacuation destiné à être monté en aval du couteau d'une machine à refendre les peaux brutes et propre à rationaliser le regroupement des peaux après refente en permettant l'empilage régulier suivant une série de piles ménagées à l'intérieur d'un caisson usuel de réception, ledit dispositif étant ainsi apte à réduire la main-d'oeuvre habituellement affectée à ce type d'opération.The present invention relates to an evacuation device intended to be mounted downstream of the knife of a machine for splitting raw skins and capable of rationalizing the grouping of skins after slitting by allowing regular stacking according to a series of housed piles. inside a usual reception box, said device thus being able to reduce the manpower usually assigned to this type of operation.

On sait qu'à l'heure actuelle dans les machines destinées à refendre les peaux brutes ou tannées en vue de séparer la partie supérieure de chaque peau ou "fleur" et la "croûte" ou partie carnée disposée immédiatement au-dessous, cette opération étant généralement effectuée au début du travail, les peaux issues de la machine sont évacuées manuellement à l'aide de pinces par une équipe d'opérateurs qui en effectuent l'empilage à l'intérieur d'un caisson de réception approprié, duquel lesdites peaux sont ensuite extraites pour des travaux ultérieurs.We know that at present in machines intended to split raw or tanned hides in order to separate the upper part of each skin or "flower" and the "crust" or meaty part immediately below, this operation being generally carried out at the start of work, the skins from the machine are removed manually using forceps by a team of operators who stack them inside an appropriate receiving box, from which said skins are then extracted for further work.

En fonction des dimensions des peaux le travail d'évacuation peut nécessiter de deux à quatre opérateurs qui doivent être parfaitement habitués à cette fonction, laquelle nécessite un effort physique important et implique par ailleurs des risques non négligeables en rapport aussi bien avec l'hygiène qu'avec les accidents qui peuvent survenir.Depending on the dimensions of the skins, the evacuation work may require two to four operators who must be perfectly accustomed to this function, which requires significant physical effort and also involves significant risks related to both hygiene and 'with accidents that may occur.

Moyennant adoption du dispositif d'évacuation suivant l'invention, l'opération d'extraction des peaux traitées par la machine à refendre et le dépôt de celles-ci à l'intérieur du caisson de réception sont rationalisés et permettent de réduire, sinon de supprimer totalement, la main-d'oeuvre qualifiée affectée à cette fonction, en éliminant de ce fait l'effort physique et les risques d'accidents.By adopting the evacuation device according to the invention, the operation of extracting the skins treated by the slitting machine and depositing them inside the receiving box are rationalized and make it possible to reduce, if not to totally eliminate the qualified workforce assigned to this function, thereby eliminating physical effort and the risk of accidents.

Le dispositif suivant l'invention comprend essentiellement un coin d'extraction qui déplace vers le haut la fleur des peaux traitées pour l'amener sur un tapis transporteur équipé le long de son brin supérieur de tambours dentés montés sur des bras autonomes, lesquels tambours maintiennent la peau appliquée contre le tapis précité suivant une force déterminée prévue réglable. Le tapis transporteur amène les peaux dans le caisson de réception, moyennant interposition éventuelle d'un second tapis extensible qui n'est utilisé que dans le cas où il est nécessaire de réaliser plusieurs piles de peaux à l'intérieur de caissons de grandes dimensions.The device according to the invention essentially comprises an extraction wedge which moves the flower of the treated skins upwards to bring it onto a conveyor belt fitted along its upper strand with toothed drums mounted on autonomous arms, which drums keep the skin applied against the aforementioned carpet according to a determined force provided for adjustable. The conveyor belt brings the skins into the receiving box, with the possible interposition of a second extensible belt which is only used in the case where it is necessary to make several piles of skins inside large boxes.

Le dispositif d'évacuation est préférablement monté sur un chariot mobile le long de rails afin de permettre d'éloigner ledit dispositif de la machine à refendre lorsqu'il s'agit de procéder aux opérations de nettoyage et de manutention de celle-ci.The evacuation device is preferably mounted on a mobile carriage along rails in order to allow the device to be moved away from the slitting machine when it comes to carrying out the cleaning and handling operations thereof.

Suivant une autre caractéristique du dispositif, les parois diagonales basses de guidage qui maintiennent les peaux sur le tapis transporteur destiné à les amener jusqu'au caisson de réception, sont munies de guides latéraux équipés de galets tournants à axe vertical, ceci'afin de permettre l'avance des peaux sans friction au niveau de leurs bords et de faciliter ainsi l'acheminement de celles-ci sur le transporteur de sortie.According to another characteristic of the device, the low diagonal guide walls which hold the skins on the conveyor belt intended to bring them to the receiving box, are provided with lateral guides equipped with rotating rollers with a vertical axis, this in order to allow the advance of the skins without friction at their edges and thus facilitating the routing of these on the output conveyor.

Pour améliorer l'adhérence de la fleur des peaux sur le tapis transporteur, on prévoit avantageusement un mécanisme qui permet d'appliquer un effort de pression sur les tambours dentés fous qui guident lesdites peaux, en maintenant celles-ci à plat à la sortie de l'opération de refente. Ce mécanisme comprend des vis de réglage dont chacune agit sur un ressort et qui permet de régler de manière exacte l'effort de pression sus-indiqué en fonction du type des peaux à travailler, une vis de fin de course réglable étant en outre prévue pour déterminer le déplacement maximal vers le bas des tambours précités par rapport au tapis transporteur.To improve the adhesion of the skin of the skins to the conveyor belt, a mechanism is advantageously provided which makes it possible to apply a pressure force to the crazy toothed drums which guide said skins, by keeping them flat at the outlet of the slitting operation. This mechanism comprises adjustment screws, each of which acts on a spring and which makes it possible to precisely adjust the above-mentioned pressure force as a function of the type of skins to be worked, an adjustable end-of-stroke screw being further provided for determining the maximum downward movement of the aforementioned drums relative to the conveyor belt.

Suivant une variante d'exécution de l'invention, on'dote le dispositif de deux caissons latéraux de réception ainsi que d'un tapis transporteur supplémentaire disposé à la suite du tapis transporteur principal mais orienté transversalement par rapport à celui-ci, ce tapis supplémentaire étant susceptible d'être commandé aussi bien dans un sens que dans l'autre en vue de décharger les peaux dans l'un ou l'autre des deux caissons, en conférant ainsi à l'opérateur la possibilité d'éloigner du dispositif celui des caissons qui est rempli et de le remplacer par un caisson vide pendant que l'autre continue à être chargé.According to an alternative embodiment of the invention, the device is provided with two lateral receiving boxes as well as an additional conveyor belt arranged after the main conveyor belt but oriented transversely relative to the latter, this additional mat being capable of being controlled as well in one direction as in the other in order to discharge the skins in one or the other of the two boxes, thereby giving the operator the possibility of moving the one of the boxes which is filled away from the device and replacing it with an empty box while the other continues to be charged.

The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:
  • Fig. 1 is a side view of a device according to the invention produced in accordance with a first embodiment.
  • Fig. 2 is the plan view from above.
  • Fig. 3 is a detailed view of the cutting mechanism shown in circle III of FIG. 1.

  • Fig. 5 is the side view of a second embodiment.
  • Fig. 6 is the plan view from above corresponding to FIG. 5.

Comme montré en fig. 1 et 2 la fleur de chaque peau traitée, détachée par le couteau de la machine à refendre, est déplacée vers le haut par un coin 1 jusqu'à venir se disposer sur un tapis transporteur 2 ; à ce dernier sont associées deux rangées de galets 3 et 4 à axe vertical qui font converger les peaux vers un tapis transporteur de sortie 5, lequel les amène dans un caisson de réception 6.As shown in fig. 1 and 2 the flower of each treated skin, detached by the knife of the slitting machine, is moved upwards by a wedge 1 until it is placed on a conveyor belt 2; associated with the latter are two rows of rollers 3 and 4 with a vertical axis which converge the skins towards an outlet conveyor belt 5, which brings them into a receiving box 6.

Pour permettre la pose des peaux dans différentes positions à l'intérieur du caisson 6, on fait en sorte que le tapis transporteur 5 puisse se déplacer longitudinalement en avant ou en arrière par rapport au tapis transporteur 2. Ce déplacement est assuré par des pistons mobiles 5' qui sortent d'un vérin 5" solidaire d'un chariot 7, lequel permet de décharger les peaux dans le caisson 6 à des emplacements différents, suivant les piles qu'on entend réaliser à l'intérieur dudit caisson.To allow the laying of the skins in different positions inside the box 6, we make sure that the conveyor belt 5 can move longitudinally forward or backward relative to the conveyor belt 2. This movement is ensured by movable pistons 5 'which exit from a jack 5 "secured to a carriage 7, which allows the skins to be discharged into the box 6 at different locations, depending on the batteries that are intended to be produced inside said box.

L'ensemble complet comprenant les tapis transporteurs 2 et 5 et les mécanismes correspondants de guidage est monté sur le chariot 7 sur lequel sont en outre prévues les commandes du dispositif ; ce chariot 7 se déplace sur des rails 8 qui une fois le caisson 6 évacué peuvent être prolongés par des rails 9, ceux-ci étant susceptibles par pivotement suivant un axe 10 d'être rabattus jusqu'à la position montrée en tracé interrompu eh fig. 1.The complete assembly comprising the conveyor belts 2 and 5 and the corresponding guide mechanisms is mounted on the carriage 7 on which the controls of the device are also provided; this carriage 7 moves on rails 8 which once the box 6 evacuated can be extended by rails 9, these being susceptible by pivoting along an axis 10 to be folded down to the position shown in broken lines eh fig . 1.

Il est ainsi possible d'éloigner l'ensemble du dispositif de la machine à refendre référencée 11, en vue de permettre le nettoyage et la manutention de celle-ci, bien entendu supposée à l'arrêt.It is thus possible to move the entire device away from the slitting machine referenced 11, in order to allow cleaning and handling thereof, of course assumed to be stopped.

Le dispositif comprend également des tambours 12 et 13 destinés à presser la fleur des peaux qui s'élève sur le tapis transporteur 2 sous l'effet du coin 1. L'effort de pression est réglable à l'intérieur de limites assez larges grâce à des vis de réglage 14 (fig. 4) montées sur des plaquettes 15 solidaires des leviers 16 qui supportent les tambours 12, lesdits leviers étant articulés en 16' en un point fixe du dispositif. Ces vis 14 peuvent pénétrer plus ou moins à l'intérieur de ressorts 17 montés sur des oreilles fixes 18, en permettant de la sorte de conférer aux tambours 12 une pression élastique d'amplitude bien déterminée, cette pression pouvant être réglée.The device also includes drums 12 and 13 intended to press the skin flower which rises on the conveyor belt 2 under the effect of the wedge 1. The pressure force is adjustable within fairly wide limits thanks to adjustment screws 14 (fig. 4) mounted on plates 15 integral with the levers 16 which support the drums 12, said levers being articulated at 16 'at a fixed point of the device. These screws 14 can penetrate more or less inside springs 17 mounted on fixed ears 18, thereby allowing to confer on the drums 12 an elastic pressure of well-defined amplitude, this pressure being adjustable.

Un mécanisme analogue à vis est associé aux leviers 19 qui sont articulés en 19' et qui supportent les tambours 13 du second groupe, avec un résultat bien entendu identique.A screw-like mechanism is associated with the levers 19 which are articulated in 19 'and which support the drums 13 of the second group, with an obviously identical result.

On observera que des vis 20 munies d'un écrou de blocage réalisent un organe de fin de course pour le réglage de la hauteur des tambours 12 ou 13 au-dessus du tapis transporteur 2. Bien entendu chaque tambour 12 ou 13 est équipé de vis de réglage indépendantes 14 et de vis de fin de course individuelles 20.It will be observed that screws 20 provided with a locking nut provide an end of travel member for adjusting the height of the drums 12 or 13 above the conveyor belt 2. Of course each drum 12 or 13 is equipped with screws independent adjustment 14 and individual limit switch screws 20.

Dans la variante de réalisation illustrée en fig. 5 et 6, on prévoit de disposer à la suite du tapis transporteur 2 un tapis transporteur 21 orienté tranversalement et qui peut être actionné dans les deux directions opposées F et F' en vue de permettre le déchargement des peaux dans l'un ou l'autre de deux caissons 22 et 23, disposés latéralement par rapport au dispositif, vis-à-vis des extrémités dudit tapis transporteur 21.In the variant embodiment illustrated in FIG. 5 and 6, provision is made to have, following the conveyor belt 2, a conveyor belt 21 oriented transversely and which can be actuated in the two opposite directions F and F 'in order to allow the unloading of the skins in one or the another of two boxes 22 and 23, arranged laterally with respect to the device, with respect to the ends of said conveyor belt 21.

Cette disposition permet de disposer les peaux, par exemple dans le caisson 22 pendant que le caisson 23 antérieurement chargé est éloigné du dispositif pour être remplacé par un caisson vide.This arrangement makes it possible to arrange the skins, for example in the box 22 while the previously loaded box 23 is moved away from the device to be replaced by an empty box.

En d'autres termes cet agencement permet un fonctionnement ininterrompu par substitution des caissons au fur et à mesure de leur remplissage, sans qu'il soit besoin d'arrêter à cet effet la machine à refendre 11.In other words, this arrangement allows uninterrupted operation by replacing the boxes as they are filled, without the need to stop the slitting machine 11 for this purpose.

On comprend que le tapis transporteur transversal 21 et le tapis transporteur longitusinal 2 sont susceptibles d'être déplacés à l'arrière de la-machine à refendre, par exemple jusqu'à atteindre la position indiquée en tracé interrompu en fig. 5, en même temps que l'ensemble supporté par le chariot 7, ceci de façon à permettre les opérations de nettoyage et de manutention de la machine 11.It is understood that the transverse conveyor belt 21 and the longitusinal conveyor belt 2 are capable of being moved to the rear of the slitting machine, for example until reaching the position indicated in broken line in FIG. 5, at the same time as the assembly supported by the carriage 7, this so as to allow the cleaning and handling operations of the machine 11.

Les avantages présentés par le dispositif suivant l'invention se comprennent aisément. Une seule personne peut éventuellement sufffire pour la surveillance de son bon fonctionnement, en éliminant tout effort physique pour l'évacuation de le fleur des peaux et pour la réalisation d'une ou de plusieurs piles à l'intérieur du ou des caissons de réception.The advantages presented by the device according to the invention are easily understood. Only one person may sufffire for the monitoring of its good functioning, by eliminating any physical effort for the evacuation of the flower of the skins and for the realization of one or more piles inside the reception box (es).
