  • Patent number: 11427415
    Abstract: An automatic loading and unloading device includes a frame, an unloading unit, a receiving unit and a receiving link unit. The frame defines a processing area, an unloading area and a receiving area. The unloading unit includes an unloading slide rail, and an unloading drive group movably disposed on the unloading slide rail for driving at least one plate to move from the processing area to the unloading area. The receiving unit includes a receiving slide rail, and a receiving lift group movably disposed on the receiving slide rail for driving the at least one plate to move from the unloading area to the receiving area. The receiving link unit interconnects the unloading drive group and the receiving lift group.

  • Patent number: 10939731
    Abstract: An automatic shoe-lacing system includes a support unit for supporting a shoe upper thereon, a robotic arm unit disposed to hold an end portion of a shoelace to move along an eyelet passing path through predetermined shoelace eyelets of the shoe upper, and at least one hook unit. The hook unit has a hook disposed to hold and tense a flexible lace body of the shoelace to prevent twist of the shoelace during the shoe-lacing operation.

  • Patent number: 10555583
    Abstract: An automatic shoe-lacing machine for securing a shoelace onto a shoe upper includes a jig unit, a robotic arm unit and a control unit. The jig unit permits the shoe upper to be disposed thereon. The robotic arm unit is disposed at the proximity of the jig unit. The robotic arm unit simultaneously holds and moves two tipping members of the shoelace for sequentially passing the tipping members through eyelets formed in the shoe upper. The control unit controls the movement of the robotic arm unit.
