Abstract
(EN)
The present invention relates to a method and a device for handling artillery shells (14-16) when loading artillery guns (1) that have an integral shell magazine (9) fixed in the traverse system but independent from the elevating mass, which magazine on command feeds out shells (14-16) one by one with a specific linear velocity in the longitudinal axis of each shell. Each shell is subsequently transferred to the loading position for the gun by a loading pendulum (13) and cradle (6). The basic idea behind the present invention is that the outfeed velocity of the shells (14-16) from the magazine (9) shall be braked to zero in a brake module (12) mounted on the gun while they lie in a shell carrier (17, 18) mounted on the loading pendulum (13). Immediately after the linear velocity of the shell has been braked to zero and its rear plane has been reversed to a pre-defined position the shell carrier (17, 18) takes over the handling of the shell and re-angles it to coincide with the angle of elevation of the gun, and transfers the shell to a laterally displaceable shell loading cradle (6).

Cette invention concerne une méthode et un dispositif de manutention des obus d'artillerie (14-16) lors du chargement de canons d'artillerie (1) munis d'un magasin pour obus intégré (9) fixé dans le système de pointage en direction, mais indépendamment de la masse d'élévation. Ce magasin débite les obus (14, 16) un à un selon une vitesse linéaire spécifique dans l'axe de chacun des obus. Chaque obus est transféré ultérieurement à la position de chargement par un pendule de chargement (13) et un berceau (6). Cette invention repose principalement sur l'idée que la vitesse d'amenée des obus (14-16) depuis le magasin (9) doit être ralentie jusqu'à l'arrêt dans le module de freinage (12) qui est monté sur le canon pendant que lesdits obus se trouvent dans un porte-obus (17, 18) monté sur le pendule de chargement(13). Dès que la vitesse linéaire de l'obus est redevenue nulle et que le plan arrière de l'obus a été ramené à une position déterminée, le porte-obus (17, 18) prend le relais et réoriente celui-ci de manière à le faire coïncider avec l'angle d'élévation du canon, et transfère l'obus vers un berceau de chargement (6) à déplacement latéral.
