OPERATING METHOD AND OPERATING DEVICE OF PRESS ROLL IN HIGH-SPEED CONVEYING EQUIPMENT OF SHEET BODY

摘要

PROBLEM TO BE SOLVED: To secure accuracy with respect to a conveying attitude and a conveying speed of a sheet body even if there arises a difference between abutment times of a plurality of press rolls in high-speed conveying equipment of the sheet body such as a single veneer, a cardboard or the like.;SOLUTION: In the conveying equipment where a plurality of press rolls 2 capable of idling are pivoted on an upper part of a roll conveyor 1 for conveying a single veneer 7 fast by a swingable swing arm 3 and are arranged to hoist freely to a thickness direction of the single veneer 7, an operating mechanism 4 is locked to the swing arm 3, and the single veneer 7 is pressed against the roll conveyor 1 by the press rolls 2 lowered forcibly via the operating mechanism 4 to convey it fast, compressed air is timely jetted towards a windmill-shaped wind receiving member 2a attached to the press roll 2 via a jetting member 5 of the compressed air, thereby idling the press rolls 2 to be lowered towards the single veneer 7 in advance at a peripheral speed based on a conveying speed of the roll conveyor 1 by a feeble driving force of the degree enough to idle the press rolls 2.;COPYRIGHT: (C)2013,JPO&INPIT
