Title
(EN) SYSTEM FOR REMOVING NUTS AND WASHERS FOR MILL LINERS
(ES) SISTEMA PARA RETIRO DE TUERCAS Y GOLILLAS PARA REVESTIMIENTOS DE MOLINOS

Abstract
(EN)
Current solutions: a) removing the nut first and then the washer, a slow process; and b) removing the nut together with the washer from a single hook, an unsafe process. At the end, it is finished by hand and the instability causes accidents among the operators. The proposed system uses the same basic idea of a washer with a hook but adds a second hook and a cylindrical bayonet socket that allows them to come all the way out together, without using the hands and without falling. Advantages: reduces total times, nuts and washers come all the way out together; does not need to be completed using the hands, reducing the possibility of accidents; and reduces the size of the die, as it is a single piece.

Soluciones actuales: a) sacar la tuerca primero y luego la golilla, un proceso lento. b) retirar la tuerca junto con la golilla con golilla de un solo gancho, un proceso inseguro, al final se termina a mano y la inestabilidad produce accidentes a los operadores. El sistema propuesto: usa la misma idea básica de la golilla con un gancho pero se agrega un segundo gancho y un encaje cilíndrico tipo bayoneta que permite que salgan juntas hasta el final sin usar las manos y sin caerse. Ventajas: Reduce los tiempos totales, tuercas y golillas salen juntas hasta el final. No es necesario completar usando las manos, reduciendo posibilidad de accidentes. Reduce el tamaño del dado por ser una sola pieza.

Les solutions actuelles consistent à : tout d'abord, sortir l'écrou puis la rondelle, un processus lent, b) retirer l'écrou conjointement à la rondelle avec la rondelle à crochet simple, un processus peu sûr, enfin terminer à la main, l'instabilité produisant des accidents aux opérateurs. Le système selon l'invention utilise la même idée basique de la rondelle avec crochet mais on ajoute un second crochet et un emboîtement cylindrique type baïonnette qui permet leur sortie conjointement jusqu'à la fin sans utiliser les mains et sans tomber. Les avantages sont : ledit système réduit les temps totaux, écrous et rondelles sortent conjointement jusqu'à la fin, il n'est pas nécessaire de terminer à la main, ce qui réduit la possibilité d'accidents, la taille dudit système est réduite du fait qu'il ne forme qu'un seul bloc.
