DESCRIPTION DESCRIPTION
PORTE DOIGTS POUR UNE PLUMEUSE DE VOLAILLES FINGER HOLDER FOR A POULTRY PEATHER
DOMAINE TECHNIQUE TECHNICAL AREA
La présente invention concerne un porte doigts pour une plumeuse de volailles, ainsi qu’une plumeuse de volailles comportant au moins un tel porte doigts. The present invention relates to a finger holder for a poultry plucker, as well as a poultry plucker comprising at least one such finger holder.
ÉTAT DE LA TECHNIQUE ANTÉRIEURE STATE OF PRIOR ART
Pour plumer une volaille, il est connu d’utiliser une plumeuse. Une plumeuse est une machine qui comporte une pluralité de portes doigts et chaque porte doigts est muni d’une pluralité de doigts. Chaque doigt est classiquement réalisé dans un matériau souple et peut prendre différentes formes. To pluck poultry, it is known to use a plucker. A plucking machine is a machine which has a plurality of finger holders and each finger holder is provided with a plurality of fingers. Each finger is conventionally made of a flexible material and can take different shapes.
Pour chaque porte doigts, la plumeuse présente un arbre sur lequel le porte doigts est fixé. Grâce à un système de motorisation, chaque arbre est entraîné en rotation, et le contact entre la volaille et les doigts en rotation arrache les plumes de la volaille. For each finger holder, the plucker has a shaft on which the finger holder is fixed. Thanks to a motor system, each shaft is rotated, and the contact between the poultry and the rotating fingers tears the feathers from the poultry.
Actuellement, un porte doigts prend la forme d’une platine circulaire qui est traversée par une pluralité de trous et présente au centre une empreinte dont la forme correspond à la forme de l’arbre pour assurer l’emmanchement de la platine sur l’arbre. La platine est ensuite fixée à l’arbre par une vis. Currently, a finger holder takes the form of a circular plate which is crossed by a plurality of holes and has in the center an imprint whose shape corresponds to the shape of the shaft to ensure the fitting of the plate on the shaft . The plate is then fixed to the shaft by a screw.
Lorsqu’un doigt est usé, il est nécessaire de le remplacer. Dans le cadre des portes doigts actuellement utilisés, chaque doigt présente une rainure circulaire qui se clipse autour du bord du trou correspondant et il est nécessaire de démonter le porte doigts de son arbre, de retirer le doigt usé en le coupant avec un outil ou un couteau, de remonter un doigt neuf en l’introduisant dans le trou correspondant, le clipser de force à la main, ou en utilisant une machine pneumatique puis de remonter la platine. Le démontage et le remontage de la platine sont des opérations relativement longues durant lesquelles la plumeuse est immobilisée. When a finger is worn, it must be replaced. In the context of the finger holders currently used, each finger has a circular groove which clips around the edge of the corresponding hole and it is necessary to disassemble the finger holder from its shaft, remove the worn finger by cutting it with a tool or a knife, reassemble a new finger by inserting it into the corresponding hole, clip it forcibly by hand, or using a pneumatic machine then reassemble the plate. Dismantling and reassembling the plate are relatively long operations during which the plucking machine is immobilized.
Dans certaines installations, il est également possible de changer les doigts sans démonter les platines, mais l’opération nécessite l’utilisation de couteaux et d’outils coupants dans des conditions précaires à l’intérieur de la plumeuse ce qui rend l’opération pénible et dangereuse. En outre, la face de la platine qui est à l’opposé des doigts présente de nombreuses anfractuosités, en particulier du fait des trous et des rainures, dans lesquelles des déchets se fixent et le nettoyage nécessite alors également le démontage de chaque platine. In certain installations, it is also possible to change the fingers without dismantling the plates, but the operation requires the use of knives and cutting tools in precarious conditions inside the plucker which makes the operation painful and dangerous. In addition, the face of the plate which is opposite the fingers has numerous crevices, in particular due to the holes and grooves, in which waste is fixed and cleaning then also requires the dismantling of each plate.
Lorsque les platines ne sont pas démontées pour le changement de doigts, la face de la platine qui est opposée aux doigts reste inaccessible et elle n’est pas désinfectée correctement ce qui peut entraîner un risque élevé de contamination bactériologique. Il est donc nécessaire de trouver un arrangement qui permet un gain de temps, en particulier pour remplacer les doigts usés, et qui selon un mode de réalisation particulier permet de résoudre le problème d’encrassement et de développement de bactéries en milieu alimentaire. Le document FR-A-2 019 911 divulgue un porte doigt de l’état de la technique. When the plates are not dismantled for changing fingers, the side of the plate which is opposite the fingers remains inaccessible and it is not properly disinfected, which can lead to a high risk of bacteriological contamination. It is therefore necessary to find an arrangement which saves time, in particular for replacing worn fingers, and which according to a particular embodiment makes it possible to resolve the problem of clogging and the development of bacteria in the food environment. Document FR-A-2 019 911 discloses a state-of-the-art finger ring.

EXPOSÉ DÉTAILLÉ DE MODES DE RÉALISATION DETAILED DESCRIPTION OF EMBODIMENTS
La Fig. 1 montre un porte doigts 100 selon l’invention pour une plumeuse de volailles. Le porte doigts 100 est mobile en rotation autour d’un axe de rotation X. La Fig. 3 montre le porte doigts 100 en coupe par un plan axial passant par l’axe de rotation X. Fig. 1 shows a finger holder 100 according to the invention for a poultry plucking machine. The finger holder 100 is movable in rotation around an axis of rotation X. FIG. 3 shows the finger holder 100 in section through an axial plane passing through the axis of rotation X.
Le porte doigts 100 comporte une platine 102 et un couvercle 104. La platine 102 est circulaire et coaxiale avec l’axe de rotation X et elle présente un bord 103 formant une surface cylindrique autour de l’axe de rotation X entre une face arrière 102a et une face avant 102b de la platine 102. La face arrière 102a est du côté de la plumeuse 10 et la face avant 102b est à l’opposé. Les faces arrière 102a et avant 102b sont ici globalement perpendiculaires à l’axe de rotation X. The finger holder 100 comprises a plate 102 and a cover 104. The plate 102 is circular and coaxial with the axis of rotation X and it has an edge 103 forming a cylindrical surface around the axis of rotation and a front face 102b of the plate 102. The rear face 102a is on the side of the plucker 10 and the front face 102b is on the opposite side. The rear faces 102a and front faces 102b are here generally perpendicular to the axis of rotation X.
En utilisation, la platine 102 est fixée à l’arbre 50 grâce à des moyens de fixation. Dans le mode de réalisation de l’invention présenté à la Fig. 3, la platine 102 est emmanchée sur un arbre 50 de la plumeuse 10. L’arbre 50 est entraîné en rotation autour de son axe par un système de motorisation de la plumeuse 10 et la platine 102 est alors entraînée en rotation autour de l’axe de rotation X correspondant à l’axe de l’arbre 50 après assemblage. In use, the plate 102 is fixed to the shaft 50 using fixing means. In the embodiment of the invention presented in Fig. 3, the plate 102 is fitted onto a shaft 50 of the plucker 10. The shaft 50 is driven in rotation around its axis by a motorization system of the plucker 10 and the plate 102 is then driven in rotation around the axis of rotation X corresponding to the axis of the shaft 50 after assembly.
La platine 102 présente ici un alésage 401 traversant et coaxial avec l’axe X pour permettre son emmanchement sur l’arbre 50. L’alésage 401 s’étend ainsi entre la face arrière 102a et la face avant 102b. The plate 102 here has a through bore 401 and coaxial with the axis
Dans le mode de réalisation de l’invention présenté ici, pour fixer la platine et empêcher la rotation de la platine 102 par rapport à l’arbre 50, la platine 102 présente au niveau de sa face avant 102b et autour de l’alésage 401, un évidement 402 dont la forme évidée intérieure, par exemple rectangulaire, est complémentaire à la forme d’une rondelle 404 agencée à l’intérieur de l’évidement 402 et fixée dans ledit évidement 402, ici par serrage d’une vis de serrage 406 serrée dans l’arbre 50. La rondelle 404 est ainsi prise en sandwich entre l’arbre 50, le fond de l’évidement 402 et la tête de la vis de serrage 406. In the embodiment of the invention presented here, to fix the plate and prevent the rotation of the plate 102 relative to the shaft 50, the plate 102 presents at its front face 102b and around the bore 401 , a recess 402 whose internal recessed shape, for example rectangular, is complementary to the shape of a washer 404 arranged inside the recess 402 and fixed in said recess 402, here by tightening a tightening screw 406 clamped in the shaft 50. The washer 404 is thus sandwiched between the shaft 50, the bottom of the recess 402 and the head of the clamping screw 406.
Le couvercle 104 présente un disque 106 qui présente une face intérieure 106a orientée vers la face avant 102b de la platine 102 et une face extérieure 106b orientée à l’opposé. Le disque 106 est ainsi positionné en regard de la face avant 102b de la platine 102 et la recouvre. Le disque 106 est ici coaxial avec l’axe de rotation X. The cover 104 has a disk 106 which has an interior face 106a oriented towards the front face 102b of the plate 102 and an exterior face 106b oriented opposite. The disc 106 is thus positioned facing the front face 102b of the plate 102 and covers it. Disc 106 is here coaxial with the axis of rotation X.
Le disque 106 est percé d’une pluralité de trous 108, où chaque trou 108 reçoit un doigt 110. La face avant 102b de la platine 102 est la face à partir de laquelle les doigts 110 vont s’étendre. The disc 106 is pierced with a plurality of holes 108, where each hole 108 receives a finger 110. The front face 102b of the plate 102 is the face from which the fingers 110 will extend.
La Fig. 2 montre un exemple d’un doigt 110 qui comporte un sabot 202 et une tige 204 avec une base en tronc de cône qui s’élargit au niveau de la jonction avec le sabot 202. Le doigt 110 est réalisé dans un matériau souple et la mise en place du doigt 110 consiste à introduire l’extrémité libre de la tige 204 dans le trou 108 depuis la face intérieure 106a jusqu’à forcer le tronc de cône dans le trou 108. Le sabot 202 se trouve alors du côté de la face intérieure 106a, et il est serré entre la face avant 102b de la platine 102 et la face intérieure 106a du disque 106, et la tige 204 du côté de la face extérieure 106b. Fig. 2 shows an example of a finger 110 which comprises a shoe 202 and a rod 204 with a truncated cone base which widens at the junction with the shoe 202. The finger 110 is made of a flexible material and the positioning the finger 110 consists of introducing the free end of the rod 204 into the hole 108 from the interior face 106a until forcing the truncated cone in the hole 108. The shoe 202 is then on the side of the inner face 106a, and it is clamped between the front face 102b of the plate 102 and the inner face 106a of the disc 106, and the rod 204 on the side of the exterior face 106b.
Cette conception garantit la tenue de la tête du doigt 110 et de l’étanchéité de l’assemblage entre la platine 102 et le disque 106 et prévient l’introduction de déchets entre le doigt 110 et le trou 108 du fait de l’absence de la rainure circulaire présente dans le cas de l’état de la technique. This design guarantees the holding of the head of the finger 110 and the tightness of the assembly between the plate 102 and the disc 106 and prevents the introduction of waste between the finger 110 and the hole 108 due to the absence of the circular groove present in the case of the state of the art.
Le couvercle 104 présente une jupe 107 qui est cylindrique et qui s’étend depuis le disque 106 vers la platine 102 de manière à recouvrir le bord 103 de ladite platine 102. La jupe 107 présente ainsi une surface intérieure qui est ainsi autour du bord 103. The cover 104 has a skirt 107 which is cylindrical and which extends from the disc 106 towards the plate 102 so as to cover the edge 103 of said plate 102. The skirt 107 thus has an interior surface which is thus around the edge 103 .
Pour assurer la solidarisation du couvercle 104 sur la platine 102, la surface intérieure de la jupe 107 et le bord 103 coopèrent par l’intermédiaire de filets 120 coaxiaux avec l’axe de rotation X. Dans le mode de réalisation de l’invention présenté sur la Fig. 3, le bord 103 présente un filetage et la surface intérieure du couvercle 104 présente un taraudage, mais une disposition inverse est possible. To ensure the securing of the cover 104 to the plate 102, the interior surface of the skirt 107 and the edge 103 cooperate via threads 120 coaxial with the axis of rotation X. In the embodiment of the invention presented in Fig. 3, the edge 103 has a thread and the inner surface of the cover 104 has a tapping, but a reverse arrangement is possible.
Selon un mode de réalisation particulier, le sens des filets 120 pour le dévissage est inversé par rapport au sens de rotation de l’arbre 50 pour éviter le desserrage de la platine 102 lors du fonctionnement de la plumeuse 10. According to a particular embodiment, the direction of the threads 120 for unscrewing is reversed with respect to the direction of rotation of the shaft 50 to avoid loosening of the plate 102 during operation of the plucking machine 10.
Ainsi, après avoir inséré les doigts 110 dans les trous 108 du couvercle 104, ce dernier peut être fixé sur la platine 102 par serrage autour de l’axe de rotation X. Le démontage s’effectue de la manière inverse. Thus, after inserting the fingers 110 into the holes 108 of the cover 104, the latter can be fixed on the plate 102 by tightening around the axis of rotation X. Disassembly is carried out in the reverse manner.
La fixation par filets 120 entre le couvercle 104 et la platine 102 assure une mise en place aisée et une bonne étanchéité en prévenant l’introduction de déchets entre eux. The fixing by threads 120 between the cover 104 and the plate 102 ensures easy installation and good sealing by preventing the introduction of waste between them.
En outre, dans le mode de réalisation décrit ici, le serrage du sabot 202 entre la platine 102 et le disque 106 réalise une compression du sabot 202 et assure la création de forces de frottement entre les sabots 202 et la platine 102, ce qui prévient le desserrage du couvercle Furthermore, in the embodiment described here, the tightening of the shoe 202 between the plate 102 and the disc 106 compresses the shoe 202 and ensures the creation of friction forces between the shoes 202 and the plate 102, which prevents loosening the cover
