Abstract

The low-pressure vaned wheel comprises outer and inner rims (1b,1c) linked by a series of vanes (1a) formed in one piece. The rims offer a degree of compliance when in contact with the products such that they can be conveyed with minimal damage.

Description

ROUES A BASSE PRESSION DITES A LAMELLESLOW PRESSURE WHEELS SAID WITH BLADES

L'invention se rattache au secteur technique des roues obtenues à basse pression utilisables notamment comme moyen d'entrainement de produits. Le demandeur exploite des roues dites à basse pression ou à lamelles qui sont réalisées en matériau élastomère compact de type connu dans le commerce  The invention relates to the technical sector of wheels obtained at low pressure which can be used in particular as a means of driving products. The applicant uses so-called low pressure or flap wheels which are made of compact elastomeric material of a type known in the trade.

Une roue de ce type est représentée à la figure 1 du dessin pour illustrer sa configuration. Cette roue se présente sous la forme d'un anneau (1) agencé avec une pluralité de lamelles (la) orientées et profilées en forme d'aubes et joignant la partie périphérique extérieure (lb) de l'anneau et la partie  A wheel of this type is shown in Figure 1 of the drawing to illustrate its configuration. This wheel is in the form of a ring (1) arranged with a plurality of oriented lamellae (la) in the form of blades and joining the outer peripheral part (lb) of the ring and the part

Ce type de roue est largement exploité par le demandeur dans de nombreuses applications. Elles peuvent être montées par exemple sur des machines permettant à grande vitesse le traitement de plis, lettres ou similaires, ou bien sur des automatismes de distribution de cartonnages par exemple. En fait, ces roues présentent, de par leur matériau élastomère compact constitutif, une certaine flexibilité qui est appropriée à la mise en contact avec les produits, plis, lettres, cartons, pouvant présenter une épaisseur variable, et ce, selon un  This type of wheel is widely used by the applicant in numerous applications. They can be mounted for example on machines allowing high-speed processing of folds, letters or the like, or else on automatic cardboard dispensing machines for example. In fact, these wheels have, by their constitutive compact elastomeric material, a certain flexibility which is suitable for bringing them into contact with products, plies, letters, cartons, which may have a variable thickness, and this, according to a

La démarche du demandeur s'est donc orientée dans une recherche d'amélioration de la durée de vie et d'utilisation de ces roues à basse pression  The applicant's approach was therefore oriented towards a search for improvement in the life and use of these low pressure wheels.

dites à lamelles.tell slats.

Une orientation était dans la modification de la structure de la roue en adjoignant des inserts de renforcement. La durabilité n'a cependant pas été confirmée. Le demandeur s'est donc orienté dans l'étude des matériaux pouvant constituer ladite roue en ayant à l'esprit les contraintes élevées dues aux efforts de sollicitation. Les différentes recherches ont ainsi amené le demandeur à mettre en valeur la  An orientation was in the modification of the structure of the wheel by adding reinforcing inserts. Durability has not been confirmed, however. The applicant therefore turned to the study of the materials that could constitute said wheel, bearing in mind the high stresses due to the stressing forces. The various searches thus led the applicant to highlight the

particularité d'un matériau spécifique.  particularity of a specific material.

La roue comprend une pluralité de lamelles orientées et profilées en forme  The wheel comprises a plurality of oriented and shaped profiled lamellae

d'aubes réalisées monobloc et susceptibles de déformation.  blades made in one piece and susceptible to deformation.

Ainsi, l'invention vise à réaliser une roue basse pression dite à lamelles qui est remarquable en ce qu'elle est fabriquée à partir d'un matériau mousse microcellulaire notamment du type connu sous la marque VULKOLLAN  Thus, the invention aims to produce a low pressure wheel called a lamella which is remarkable in that it is made from a microcellular foam material in particular of the type known under the brand VULKOLLAN

appartenant à la société BAYER AKTIENGESELLSCHAFT.  belonging to the company BAYER AKTIENGESELLSCHAFT.

Ce matériau mousse microcellulaire est à base de matière plastique et succédanés de caoutchouc et offre une plus grande souplesse pour l'absorption des variations d'épaisseur des produits destinés à être entraînés selon les automatismes du type précité. Par ailleurs, la tenue dans le temps est très largement supérieure à celle des élastomères compacts utilisés précédemment, et dans un ordre de grandeur entre cinq à dix fois celui des matériaux  This microcellular foam material is based on plastic and rubber substitutes and offers greater flexibility for the absorption of variations in thickness of the products intended to be driven according to the automations of the aforementioned type. Furthermore, the resistance over time is very much greater than that of the compact elastomers used previously, and in an order of magnitude between five to ten times that of the materials.

élastomères compacts du type précité.  compact elastomers of the aforementioned type.

Les avantages ressortent bien de l'invention. On souligne notamment l'augmentation considérable de la durée d'utilisation des roues à basse pression dites à lamelles par le choix sélectif du matériau. Les caractéristiques  The advantages emerge clearly from the invention. In particular, the considerable increase in the service life of so-called low-pressure flap wheels is emphasized by the selective choice of material. Characteristics
