Abstract:At present, the bottle filling process in soft capsule production line has higher requirements on label orientation. The consistency of the label orientation will directly or indirectly affect the aesthetics of the product packaging. Usually, this process mainly involves manual tray packing, consuming a lot of manpower while being inefficient. An automatic tray packing workstation for the soft capsule line was designed and developed, with the truss manipulator as the main actuator, supporting the LR-W70 color mark detection sensor and other detection components, through the identification of the capsule bottle label, bottle conveying and positioning control, and plastic tray conveying control, the functions of product label position correction, plastic tray separation and automatic loading were realized, which could effectively reduce manual input and improve the automation level of the production line.
