Design evaluation of two-roller conveyors for semi-self-flowing transportation

Kosse, Vladis (2002) Design evaluation of two-roller conveyors for semi-self-flowing transportation. Journal of Mechanical Engineering Science, 216(12), pp. 1217-1223.


In conveyors utilizing the principle of semi-self-flowing transportation, parts are put on a surface moving in the lateral direction by means of vibration or on two rollers rotating in opposite directions. Advantages of the latter one are that parts can be supplied on demand and a very small angle of inclination is required (less than 3 degrees). Formulae found in scientific literature for the velocity of transportation as a function of the roller velocity give large discrepancies with experimental results. Extensive experimental modelling allows the dependence of the frictional coefficient on the shape of parts and the contact angle to be established. A new mathematical model of the conveyor has been developed and a new formula for the velocity of transportation has been derived, which is in good agreement with experimental data.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
