Abstract

The invention provides a lifter for a main roller and method for transporting the main roller, capable of easily adjusting the height direction and the horizontal direction of the main roller, when lifting or transporting the main roller and mounting or demounting the main roller relative to a bearing unit of a linear saw. The lifter for the main roller comprises: a moving vehicle with a pillar for lifting and guiding; a lifting part supported on the pillar and capable of freely lifting along the pillar; a horizontal moving part supported on the lifting part and capable of horizontally moving; a horizontal protruding part capable of freely asway being supported on the horizontal moving part using the support axle of the horizontal direction; a pair of support forks mounted on the horizontal protruding part and comprising roller support parts for supporting fork ends at the two ends of the main roller of the linear saw as the transporting and keeping object; and a pressing rod for pressing the fork ends on the roller support parts of the support forks.

Description

technical field [0001] The present invention relates to a lifter used when holding and conveying a main roller of a wire saw, when attaching the main roller to a bearing unit of a wire saw, and when detaching the main roller from a bearing unit of a wire saw, and utilizing The main roller conveying method of the elevator. Background technique [0002] As a wire saw, a wire rod is wound multiple times between a plurality of main rollers, and the running wire rod is brought into contact with a workpiece such as a semiconductor, thereby cutting the workpiece to a predetermined thickness. When assembling this wire saw, there is a work of attaching the main roller to the bearing unit. Also, on the user side of the wire saw, when the main roller is worn or the cutting specifications of the workpiece are changed, there is work to remove the main roller from the bearing unit of the main roller and attach another main roller to the bearing unit. [0003] Patent Document 1 discloses...
