Title:
WORKPIECE TRANSPORT DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/022334
Kind Code:
A1
Abstract:
A transfer feeder (5) is provided with a pair of support sections (6) and lift clamp drive mechanisms (7). The pair of support sections (6) supports a finger (200), which holds a workpiece (W), so that the finger (200) can move in a transport direction (X). The lift clamp drive mechanisms (7) are respectively provided to the support sections (6), and move the support sections (6) in a lift direction (Z) and in a clamp direction (Y). Each of the lift clamp drive mechanisms (7) has a first drive section (71), a second drive section (72), a first link mechanism (73), and a second link mechanism (74). The first drive section (71) and the second drive section (72) respectively have a first electric motor (711) and a second electric motor (721), which serve as power sources for moving the support sections (6) in the lift direction (Z) and in the clamp direction (Y). The first link mechanisms (73) connect the first drive sections (71) and the support sections (6), and the second link mechanisms (74) connect the second drive sections (72) and the support sections (6).
