Patent ID: 7481310

Claim:
A panel transportation device comprising: (a) a panel grasp portion for grasping a panel; (b) a link mechanism for moving the panel grasp portion in a panel transportation direction; and (c) a slide mechanism for operating the link mechanism so as to move the panel grasp portion in the panel transportation direction and moving the entire link mechanism, wherein the slide mechanism is constituted of a first slide mechanism and a second slide mechanism provided closer to a transportation line downstream side than the first slide mechanism; the first slide mechanism has a first slide block connected to the link mechanism, and is configured to linearly drive the first slide block, the second slide mechanism has a second slide block connected to the link mechanism, and is configured to linearly drive the second slide block, a move direction of the first slide block inclines relative to a move direction of the second slide block, and the link mechanism comprises i. an output member connected to the panel grasp portion; ii. a first link whose one end is pivotally connected to the output member and whose other end is pivotally connected to the first slide block; and iii. a second link whose one end is pivotally connected to the output member and whose other end is pivotally connected to the second slide block; wherein the link mechanism is constructed such that the panel grasp portion is moved in the panel transportation direction by individually and linearly driving the first slide block and the second slide block.
