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.
Claims17
An automatic shoe-lacing machine adapted for securing a shoelace onto a shoe upper, the shoelace having a flexible lace body, and two tipping members that are respectively connected to two opposite ends of the lace body, the shoe upper having two spaced-apart lace stay pieces, each of the lace stay pieces being formed with a plurality of spaced-apart eyelets, said automatic shoe-lacing machine comprising:
- a jig unit adapted to permit the shoe upper to be disposed thereon;
- a robotic arm unit disposed at the proximity of said jig unit, said robotic arm unit being adapted to simultaneously hold and move the tipping members of the shoelace for sequentially passing the tipping members through the eyelets of the shoe upper;
- and
- a control unit controlling the movement of said robotic arm unit.
A method for securing a shoelace onto a shoe upper by an automatic shoe-lacing machine, the automatic shoe-lacing machine including a robotic arm unit and a machine vision unit, the shoelace having a flexible lace body, and two tipping members that are respectively connected to two opposite ends of the lace body, the shoe upper having two spaced-apart lace stay pieces, each of the lace stay pieces being formed with a plurality of spaced-apart eyelets, said method comprising steps of:
- a) capturing, by the machine vision unit, a digital image that is related to the eyelets of the shoe upper, and determining, by the machine vision unit, the positions of two of the eyelets through which the tipping members of the shoelace would be operated to respectively pass via the digital image;
- b) passing, by the robotic arm unit, the tipping members respectively through the two eyelets, and moving, by the robotic arm unit, the tipping members away from the shoe upper such that two free end segments of the lace body that respectively connected the tipping members are crossed;
- c) holding, by the robotic arm unit, the tipping members and rotating the shoe upper and the robotic arm unit relative to each other, such that the two free end segments of the lace body are not crossed;
- and
- d) repeating steps a) to c) until the tipping members pass through all the eyelets of the shoe upper.
