<p>Articles being conveyed on a source conveyor belt with uniform spacing between them are deposited on a receiving conveyor belt with a different uniform spacing between them utilizing a device that has one or more transfer units mounted for being driven rotationally about a common axis, each transfer unit having axially extending article pickup members which all rotate or orbit in the same circular path for gripping successive articles being presented on the source conveyor and transferring the articles to the receiving conveyor. The transfer units are driven rotationally with individual servomotors which are controlled to accelerate and decelerate cyclically such that the article pickup members arrive at the source conveyor or moving at the same linear speed as the source conveyor to pickup an article and arrive at the receiving conveyor moving linearly at the same speed as the receiving conveyor to deposit the article without relative motion between the pickup members and the conveyors while picking up and while depositing the articles. <IMAGE></p> |
