Abstract

Se describe un mecanismo de transferencia de peines para una máquina gill a tornillo que comprende por lo menos una leva situada en el extremo detransferencia de cada uno de los tornillos de avance y retorno para contactar los peines y moverlos entre los tornillos de avance y retorno y viceversa. Laleva tiene un perfil en dirección posterior con respecto a su dirección de giro. Los peines transferidos se desplazan completamente desde el trayectohorizontal del siguiente peine mediante un movimiento vertical menor que el 85% de la distancia de transferencia total. El perfil de la leva es tal que lospeines se desplazan 80% o menos de su distancia de transferencia total antes de alcanzar la leva una rotación de 100° a partir del punto de contacto inicialcon el peine. El perfil de la leva se encuentra con el extremo del peine a menos de 30° debajo de la línea media horizontal entre los tornillos. Lospeines no son más de 1 cm (tres octavos de pulgada) más largos que la distancia entre los husillos de los tornillos impulsores. La aceleración impartida alpeine por la leva es gradual, se evita por completo la acción de percusión o martilleo de la mayoría de las máquinas gill anteriores. El perfil tienepreferentemente unaforma tal que lleve al peine hasta una determinada velocidad en la primera porción de la revolución de la leva que lo transfieraentre los dos juegos de tornillos. Luego el perfil desciende para que en la práctica normal, el peine no tenga contacto con la leva en absoluto. Por estemedio es posible acelerar el peine a la velocidad mínima necesaria para que efectúe una transferencia correcta y continue la aceleración más allá de estepunto, minimizando así la cantidad de retardo que deba aplicarse al peine cuando alcance su destino y permitiendo un funcionamiento mucho más veloz de laA comb transfer mechanism is described for a gill-to-screw machine comprising at least one cam located at the transfer end of each of the feed and return screws to contact the combs and move them between the feed and return screws and vice versa. Laleva has a profile in the rear direction with respect to its direction of rotation. Transferred combs move completely from the horizontal path of the next comb by vertical movement less than 85% of the total transfer distance. The cam profile is such that the combs travel 80% or less of their total transfer distance before the cam reaches a rotation of 100 ° from the point of initial contact with the comb. The cam profile meets the end of the comb less than 30 ° below the horizontal midline between the screws. The combs are not more than 1 cm (three-eighths of an inch) longer than the distance between the drive screw spindles. The acceleration imparted to the comb by the cam is gradual, the percussion or hammering action of most previous gill machines is completely avoided. The profile preferably has a shape such that it brings the comb up to a certain speed in the first portion of the cam revolution that transfers it between the two sets of screws. Then the profile descends so that in normal practice, the comb does not have contact with the cam at all. By this means it is possible to accelerate the comb to the minimum speed necessary for it to perform a correct transfer and continue acceleration beyond this point, thus minimizing the amount of delay that should be applied to the comb when it reaches its destination and allowing much faster operation of the
