Title: Cleaner device for conveyer belt
Inventor: FUJII YASUO
IPC: B65G45/12
Filed: 2003-08-08
Abstract: <P>PROBLEM TO BE SOLVED: To make a scraper easy to closely adhere to a belt surface, even if the scraper is unevenly worn.  <P>SOLUTION: This device is provided with a holding shaft 5 disposed in a belt width direction of a belt conveyor 1 and the planar scraper 12 held along the holding shaft 5 and having flexibility. The device removes deposited substances on the belt surface by bringing the scraper 12 into pressure contact with the belt surface. Since plate thickness of the scraper 12 is made thinner from the center part toward both end parts, deformation performance at both end parts of the scraper 12 is enhanced as compared with the center part. As a result, the pressure contact surfaces at both the projected end parts are deformed along the belt surface to be in even pressure contact with the center part when a pressure contact surface of the scraper center part is greatly worn out and the pressure contact surfaces at both end parts become projecting states to the belt surface side as compared with the worn out pressure contact surface at the center part, and thereby the scraper 12 is capable of closely adhering to the belt surface, even if the pressure contact surfaces are in unevenly worn out states. If each of the scrapers 12 is fixed as one divided in the belt width direction to the holding shaft 5, only a highly worn out part of the scraper 12 can be replaced and the scraper 12 becomes economical.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
