とする板状物の反転装置。 This is a reversing device for lifting a rectangular plate-like object such as a PC board in a substantially horizontal position using a crane, and changing the hoisted plate-like object to an almost vertical vertical position, and is installed at the four corners of the plate-like object. Of the four hanging points, wires are connected to the two hanging points that are on the upper side when in the vertical position, and this plate is connected to the other two hanging points that are on the lower side. By connecting dampers that naturally expand due to the weight of objects,
With these dampers retracted, the plate-like object is lifted in a substantially horizontal position via these dampers and the wire, and the damper is placed in a cylinder tube in which fluid is sealed, through which the fluid can flow. A piston in which a hole is formed is disposed, and a rod is connected to the piston, and the base end of the cylinder tube of this damper and the tip of the rod are respectively connected to the crane and the suspension point. A plate-like object that is connected directly or via a wire, and that the extension stroke of the damper is set approximately equal to the height dimension when the plate-like object is in a vertical position. reversing device.
