Abstract

The guard system consists of an inner guard plate (1) screwed to the conveyor frame anchoring brackets (4, 5) and two outer guard plates (2, 3) with slots allowing them to be adjusted to a trough angle of 25 45 degrees. The two outer plates are fixed by screws to right- and left hand anchoring brackets (6, 7).

Description

-1- La présente invention concerne un dispositif de sécurité qui assure la-1- The present invention relates to a security device which ensures the

protection des points rentrants supérieurs pour une station en auge à 3 rouleaux d'un convoyeur à bande transporteuse.(Un point rentrant est un point dangereux physiquement pour les intervenants; il se situe entre le bord des rouleaux et le dessous de la bande). Les convoyeurs en auge ont des inclinaisons de 20 , 250 ,30 ,35 et 45 . Pour chaque degré d'inclinaison, il y  protection of the upper re-entering points for a 3-roller trough station of a conveyor belt conveyor. (A re-entering point is a physically dangerous point for workers; it is located between the edge of the rollers and the underside of the belt). The trough conveyors have inclinations of 20, 250, 30, 35 and 45. For each degree of inclination, there

avait un système de protection.had a protection system.

Le dispositif selon l'invention permet de remédier à cet inconvénient. En effet, il se compose de 3 parties distinctes. (1 plaque centrale(1),1 plaque latérale gauche(2) et 1 plaque latérale droite(3)). Sur chacune des pièces latérales se trouve une forme spéciale, qui permet ainsi de régler l'inclinaison souhaitée. Ainsi, ce dispositif s'adapte aux stations en auge quelque soit  The device according to the invention overcomes this drawback. Indeed, it consists of 3 separate parts. (1 central plate (1), 1 left side plate (2) and 1 right side plate (3)). On each of the side pieces there is a special shape, which allows to adjust the desired inclination. Thus, this device adapts to trough stations whatever

Le réglage des plaques de protections latérales se fait manuellement. Le blocage de ces protections s'effectue par vissage. Le dispositif est alors fixé sur des équerres d'ancrage percées.(Ces 4 equerres sont  The side protection plates are adjusted manually. These protections are locked by screwing. The device is then fixed on pierced anchor brackets. (These 4 brackets are

Les dessins annexés illustrent l'invention: - La figure 1 représente le dispositif installé sur une station en auge à trois rouleaux - Le repère 1 représente la plaque de protection centrale - Le repère 2 représente la plaque de protection gauche - Le repère 3 représente la plaque de protection droite - Le repère 4 représente l'équerre d'ancrage intérieur gauche - Le repère 5 représente l'équerre d'ancrage intérieur droite - Le repère 6 représente l'équerre d'ancrage extérieur gauche - Le repère 7 représente l'équerre d'ancrage extérieur droite -2- En référence à ce dessin(fig.1), le dispositif comporte une pièce centrale(1) percée symétriquement par 4 trous. L'inclinaison des protections latérales gauche(2) et droite(3) ce fait par l'intermédiaire des formes et des trous percées dans ces protections.Les équerres d'ancrages intérieur gauche(4) et droite(5)sont percées de 2 trous pour la fixation de la plaque de protection centrale et l'orientation des plaques extérieurs gauche (2) et droite(3).Les équerres d'ancrage extérieur gauche(6) et droite(7) servent à la fixation des plaques de protection gauche(2) et droite(3).Les 4 équerres d'ancrage intérieur, extérieur sont fixées sur le chassis de la station en auge à 3 rouleaux soit par soudure soit par clamage(pour les sites en atmosphère  The accompanying drawings illustrate the invention: - Figure 1 represents the device installed on a trough station with three rollers - Mark 1 represents the central protective plate - Mark 2 represents the left protective plate - Mark 3 represents the right protection plate - Mark 4 represents the left interior anchor bracket - Mark 5 represents the right interior anchor bracket - Mark 6 represents the left external anchor bracket - Mark 7 represents the right external anchoring bracket -2- With reference to this drawing (fig. 1), the device comprises a central part (1) pierced symmetrically by 4 holes. The inclination of the left (2) and right (3) lateral protections is done by means of the shapes and holes drilled in these protections. The left (4) and right (5) interior anchoring brackets are pierced by 2 holes for fixing the central protection plate and the orientation of the left (2) and right (3) external plates. The left (6) and right (7) external anchoring brackets are used to fix the protection plates left (2) and right (3). The 4 interior and exterior anchoring brackets are fixed to the chassis of the station in trough with 3 rollers either by welding or by clamping (for sites in an atmosphere

Le dispositif se monte de la façon suivante: On prémonte avec des boulons M8 la plaque de protection centrale(l),les équerres d'ancrage interieur gauche(4)et droite(5),les protections extérieur gauche(2) et droite (3)et les équerres d'ancrage gauche(6) et droite(7).On présente l'ensemble des pièces sur le chassis de la station en auge à 3 rouleaux et on soude ou on clame les  The device is assembled in the following way: The central protection plate (l), the left (4) and right (5) interior anchoring brackets, the left (2) and right exterior protections are pre-assembled with M8 bolts. 3) and the left (6) and right (7) anchor brackets. We present all the parts on the station frame in 3-roller trough and we weld or clamp them
