Abstract
Official abstract text for this publication.
In transferring and conveying an article between rotation conveyance bodies, the rotation conveyance bodies ( 1, 2 ) are placed so as to have a prescribed gap between pitch circles thereof, and the article is conveyed along a transition curve whose curvature continuously varies from the pitch circle curvature of a rotation conveyance body ( 1 ) before the transfer to the pitch circle curvature of a rotation conveyance body ( 2 ) after the transfer between both the pitch circles, whereby the article is transferred and conveyed with acceleration smoothly varying and without a change in the distance between the axes of the rotation conveyance bodies.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for conveying an article, comprising the steps of: transferring the article between rotation conveyance bodies, the rotation conveyance bodies having a prescribed gap between pitch circles thereof; and conveying the article along a transition curve having a curvature that continuously varies from a first pitch circle curvature of one of the rotation conveyance bodies before transfer to a second pitch circle curvature of another one of the rotation conveyance bodies, wherein said conveying of the article between the rotation conveyance bodies is along a conveyance guide having a guide surface assuming an offset transition curve obtained by offsetting the transition curve, one of the conveyance bodies having a reduced pitch circle radius without a change in positions of axes of virtual rotation conveyance bodies that transfer the article with pitch circles thereof contacting each other, said conveying is at a conveyance speed between the rotation conveyance bodies that continuously varies from a peripheral speed of the one of the rotation conveyance bodies before the transfer to a peripheral speed of the another one of the rotation conveyance bodies after the transfer, and a ratio between angular speeds of the one of the rotation conveyance bodies before the transfer and the another one of the rotation conveyance bodies after the transfer is equal to a ratio between inverse numbers of the number of pockets of the respective rotation conveyance bodies. 2. The method for conveying the article according to claim 1 , wherein circular pitches between adjacent pockets of the rotation conveyance bodies are different from each other. 3. The method for conveying the article according to claim 1 , wherein the transition curve is represented by any of curves c 1 to c 4 calculated by any of following mathematical formulae 1 to 4: c 1 ( s ) = [ 1 α ∫ 0 α · s cos ( σ 2 2 ) d σ , 1 α ∫ 0 α · s sin ( σ 2 2 ) d σ ] [ Math . 1 ] (where s represents a length of a curve, and α is determined by a length of a transition curve and a pitch circle radius of a rotation conveyance body) c 2 ( s ) = { ∫ 0 s cos [ σ n + 1 R · s R n ( n +
