Abstract

The invention relates to the easy positioning of a protection system making it possible to eliminate accidents (tearing-off of a hand and an arm). It consists of two fastening lugs (3) perforated by an oblong hole (1) and connected by a welded metallic corner iron (2) or a screwed wooden bracket. The device according to the invention is intended particularly for protecting the reentrant angles of conveyor belts used in quarries, sand quarries, in agriculture, mines, industries, etc.

Description

SYSTEME DE PROTECTION DES POINTS OU ANGLES RENTRANTS (zones de converqence des mouvements des rouleaux et tapis)
facilement adaptables sur les axes des rouleaux.PROTECTION SYSTEM FOR INNER POINTS OR ANGLES (areas of convergence of roller and belt movements)
easily adaptable on the axes of the rollers.

DESCRIPTION
La présente invention concerne un système de protection (conforme à la réglementation par décret nx 73404 du 26.03.73 sur les bandes porteusse), des points rentrants (zones de convergence des mouvements des @ouleaux et tapis) des bandes transporteuses.DESCRIPTION
The present invention relates to a protection system (in accordance with the regulations by decree nx 73404 of 26.03.73 on the carrier belts), re-entering points (zones of convergence of the movements of the rolls and belts) of the conveyor belts.

Ce système est utilisable dans tous les domaines utilisant des bandes transporteuses : (carrières, sablières, agriculture, industries, etc...)
Aujourd@hui, la protection se fait par des grilles latérales n'assurant pas a 100% la sécurité Les statistiques de la CM M révèlent un nombre très important d'accidents du travail par arrachement de la main et du bras, dont la conséquence pour 1 ouvrier est au moins la perte complète d'un menbre ce qui génère des dépenses considérables pour la collectivité
Le dispositif revendiqué permet de remédier å cet inconvénient Il comporte en effet selon une première caractéristique une cornière de protection empêchant l'utilisateur de mettre les mains dans l'angle rentrant fait par la bande transporteuse et le rouleau, ainsi qu'a la tangente entre le rouleau et la cornière Le dispositif peut-être fixer facilement sur l'axe du rouleau en écartant légèrement la tôle des pattes de fixation est bloqué en rotation par des trous oblongs.This system can be used in all areas using conveyor belts: (quarries, sand pits, agriculture, industries, etc.)
Today, the protection is done by lateral grids not ensuring 100% safety The statistics of the CM M reveal a very important number of accidents at work by tearing of the hand and the arm, whose consequence for 1 worker is at least the complete loss of a member which generates considerable expenses for the community
The claimed device overcomes this drawback. It indeed has, according to a first characteristic, a protective angle preventing the user from putting his hands in the re-entrant angle made by the conveyor belt and the roller, as well as at the tangent between the roller and the angle iron The device can be easily fixed on the axis of the roller by slightly moving the sheet away from the fixing lugs is blocked in rotation by oblong holes.

Selon des modes particuliers de réalisation, le dispositif est constitué de 2 pattes de fixation percées par un trou oblong auxquelles peuvent être soudées une cornière métallique ou bien un tasseau de bois vissé de section correspondant au diamètre du rouleau Une bande de caoutchouc ou en mousse de polyuréthane peut-etre également collée sur la cornière métallique afin d'amortir les contacts cornière/bandes provoqués par le passage ou la chute de gros éléments. According to particular embodiments, the device consists of 2 fixing lugs pierced by an oblong hole to which can be welded a metal angle iron or else a screwed wooden cleat of section corresponding to the diameter of the roll A strip of rubber or of foam polyurethane can also be glued to the metal angle in order to absorb the angle / strip contacts caused by the passage or fall of large elements.

Le dessin en annexe illustre l'invention
Les dimensions du dispositif doivent étire adaptes a celles des rouleaux (diamètre et largeur) et de leurs axes. The accompanying drawing illustrates the invention
The dimensions of the device must be adapted to those of the rollers (diameter and width) and their axes.
