Abstract

Hollow profiled section which is flexible on the front for all types of profiled conveyor belt. The invention relates to a type of profiled section which permits simple and rapid fastening onto all types of profiled conveyor belts via mechanical attachments, these attachments being placed in the cavity of the profiled section which isolates them from the product being handled. The profiled section 1 consists of a concave sole plate 3 for ensuring leaktightness during fastening onto the belt 9. The raised flap 2 reveals a cavity intended to receive a stiffener 4 and the method for mechanical fastening which may be a bolt 5 and a nut 6 tightened by a tubular hexagon box spanner (wrench) 7. Once fastening has been achieved, the flap in the normal position protects the fastener device, preventing contact with the product being handled.

Description

DESCRIPTION
La présente invention concerne, la forme et le dispositif de fixation de profilés élastomères pour les courroies et bandes transporteuses; lesquelles, ainsi equipées permettent de manutentionner tous produits (vrac ou charge isolée) sur toutes distances, avec une inclinaison de O à 9Q'. DESCRIPTION
The present invention relates to the form and the device for fixing elastomeric profiles for belts and conveyor belts; which, thus equipped, make it possible to handle all products (bulk or isolated load) over any distance, with an inclination of O to 9Q '.

Traditionnellement les profilés sont rapportés sur leur support par vulcanisation ou par collage a froid avec dans certains cas, un renforcement de la liaison par boulons apparents. La mise en oeuvre de ces procédés nécessite un materiel spécifique et une main d'oeuvre qualifiée. La réalisation de ces courroies profilées est onéreuse, les interventions de dépannage sont longues et d'un coût élevé sans garantie de tenue des réparations faites; et ce, en raison de la technique de montage qu'impose la forme des profilés. Traditionally the profiles are attached to their support by vulcanization or by cold bonding with, in certain cases, a strengthening of the connection by visible bolts. The implementation of these processes requires specific equipment and skilled labor. The production of these profiled belts is expensive, the troubleshooting interventions are long and of a high cost without guarantee of the maintenance of the repairs made; and this, because of the mounting technique imposed by the shape of the profiles.

Selon la présente invention, la forme des profilés et le dispositif de fixation qui leur est associé permettent de réaliser des courroies et bandes transporteuses à profils ou d'effectuer un dépannage sur ces profils de façon simple, sans matériel ni outillage particulier et par tout personnel d'entretien. Les courroies profilées ainsi obtenues grâce å la présente invention ont en outre l'avantage d'empêcher les contacts entre les produits manutentionnés et le dispositif de fixation, ce qui présente un avantage important notamment lors de la manutention de produits alimentaires DESCRIPIIF DES PROPILES. According to the present invention, the shape of the profiles and the fixing device associated therewith makes it possible to produce belts and conveyor belts with profiles or to carry out troubleshooting on these profiles in a simple manner, without any particular material or tools and by any personnel. maintenance. The profiled belts thus obtained thanks to the present invention also have the advantage of preventing contact between the products handled and the fixing device, which has an important advantage in particular when handling food products.

Ils sont constitués de trois parties distinctes
- un corps d'épaisseur et de hauteur variable, droit ou incliné, (définis en fonction des produits transportés par la courroie profilée) (page 1/3. fig 1 & 2, rep. 1). They consist of three separate parts
- a body of variable thickness and height, straight or inclined, (defined according to the products transported by the profiled belt) (page 1/3. fig 1 & 2, rep. 1).

- d'un rabat mobile en partie basse sur la face arrière (page 1/3, fig 1 & 2, rep. 2). - a movable flap in the lower part on the rear face (page 1/3, fig 1 & 2, rep. 2).

- d'une semelle concave assurant après serrage l'étanchéité aux produits entre profilés et support, tout particulièrement au passage sur les tambours (entraînement, pied, renvoi, etc (page 1/3, fig 1 & 2, rep. 3). - a concave sole ensuring, after tightening, the tightness of the products between the profiles and the support, particularly when passing over the drums (drive, foot, return, etc. (page 1/3, fig 1 & 2, rep. 3).

DESCRIPTI D LI ?IIlTION
Le profilé positionné sur son support (page 2/3, fig 3), l'opérateur par une légère pression sur le haut de celui-ci, le fait basculé sur son devant. Le rabat ainsi se lève et découvre le logement pour la mise en place du raidisseur (page 2/3, fig 3 & 4, rep. 4) et des attaches mécaniques. Le raidisseur peut être en toutes matières rigides et toutes sections (L,U,plat...). Les attaches mécaniques peuvent être des boulons (vis à tête large, rondelle frein, écrou, etc) (page 3/3, fig 5, rep. 8) , des rivets (page 3/3, fig 6, rep. 9Y , etc.DESCRIPTION OF LINK
The profile positioned on its support (page 2/3, fig 3), the operator by light pressure on the top of it, tilts it on its front. The flap thus rises and discovers the housing for the installation of the stiffener (page 2/3, fig 3 & 4, rep. 4) and the mechanical fasteners. The stiffener can be made of any rigid material and any section (L, U, flat ...). The mechanical fasteners can be bolts (large head screws, lock washer, nut, etc.) (page 3/3, fig 5, ref. 8), rivets (page 3/3, fig 6, ref. 9Y, etc. .

La fixation effectuée, le profilé est alors relâché, il reprend sa position naturelle par élasticité. Le rabat arrière recouvre et dissimule le dispositif de fixation évitant dés lors le contact avec le produit transporté par la courroie ou mande transporteuse (page 3/3, fig 5 & 6). Once the fixation has been made, the profile is released, it resumes its natural position by elasticity. The rear flap covers and conceals the fixing device, thus avoiding contact with the product transported by the conveyor belt or band (page 3/3, fig 5 & 6).

Par leur forme et leur dispositif de fixation ces profilés sont simples et rapides à mettre en oeuvre et réduisent les risques au montage pour le personnel. Les courroies et bandes transporteuses équipées de ces profilés ont en outre un aspect extérieur esthétique. By their shape and their fixing device, these profiles are simple and quick to implement and reduce the assembly risks for the personnel. The belts and conveyor belts equipped with these profiles also have an aesthetic exterior appearance.
