The patented design, named the SWING-DOWN® bulk bag filler, simultaneously lowers and pivots the fill head, stopping it in a vertically-oriented position that places the bag inlet spout inflatable connection, inflator button, and four bag loop latches within one arm’s length of an operator standing on the plant floor.
“Bringing the fill head to the operator in a vertical position at floor level can significantly increase the safety and speed of connecting bulk bags,” says Gill, explaining that the connection points of a conventional filler are beyond the reach of most operators, even when short bags are being filled. “Adding the height of a roller conveyor to the height of a bulk bag to the length of its bag loops puts the connection points for bulk bags of only 48 inches (122 cm) in height at approximately 7 feet (213 cm) above the floor,” he says.
The new design is said to eliminate the danger of repeatedly stepping onto and over roller conveyors to access rear bag hooks and spout connection collars, and of standing on the conveyor and bending over with head and arms inserted beneath operational fill head components to pull bag spouts upward over inflatable collars while reaching for bag inflator buttons.
Una consola remota o un panel montado en la pared alberga los controles para elevar y girar el cabezal de llenado hasta una «posición de llenado» horizontal bloqueada, inflar automáticamente la bolsa para eliminar arrugas, abrir una válvula de control de caudal o poner en marcha un dispositivo de alimentación, y detener el flujo de material una vez que se ha alcanzado el peso de llenado preestablecido. Las plataformas vibratorias opcionales desairean y densifican el material dentro de la bolsa en puntos de ajuste preestablecidos para crear una bolsa sólida y estable, lista para su envío.
Una vez llenadas las bolsas, el controlador desinflada el collarín de conexión de la boquilla, libera los cierres de bucle y eleva el cabezal de llenado para desacoplar completamente la boquilla, lo que permite que la bolsa salga automáticamente de la llenadora y se desplace por la cinta transportadora de rodillos.
An innovative latch mechanism automatically resets the latch after releasing the bag loops, and re-positions it as the fill head pivots into a vertical position, enabling the latch to receive bag loops easily inserted by an operator and to re-latch automatically, securing the bag.
“The SWING-DOWN® filler represents a total re-think of the bulk bag filling process, allowing rapid connection of empty bags, while improving the ergonomics and safety of the task by an order of magnitude,” says Gill.
La máquina de llenado está fabricada en acero al carbono con un acabado industrial resistente, o en acero inoxidable con un acabado que cumple con las normas industriales, alimentarias, lácteas o farmacéuticas, y se ofrece con sistemas de suministro de material integrados con los equipos de proceso previos u otras fuentes de material.
