Abstract
A stoppering machine is disclosed which includes an inclined rotatable member which contacts a supply of stoppers for selectively arranging and feeding the stoppers to a stopper inserting device where they are inserted into the openings of successively presented containers such as bottles. An arrangement is also disclosed wherein the stoppers are guided to and supported at a position immediately over the openings of the successively presented containers for insertion into the openings of said containers by the inserting device. Further, an arrangement is disclosed for blocking the movement of the stoppers being guided to the aforementioned position when the inserting device inserts the stoppers into the openings of the successively supplied containers.
Claims9
In a stoppering machine for applying stoppers having a relatively wide flanged top portion and a relatively narrow bottom portion to the openings in containers such as bottles wherein means are provided for holding a supply of said stoppers and for selectively arranging and feeding the stoppers to a stopper inserting means where the stoppers are inserted into the openings of containers, the improvement comprising an inclined rotatable member which contacts said supply of stoppers, said rotatable member having supporting means thereon for supporting stoppers during rotation of said member such that stoppers are raised to where those stoppers not properly arranged in said supporting means for feeding to the stopper inserting means fall from said supporting means under the effect of gravity, said supporting means including an annular recess in said inclined rotatable member for supporting stoppers, and wherein cover means are provided over a substantial portion of said annular recess, said cover means extending radially inwardly to completely cover said annular recess and being positioned above said annular recess a predetermined distance such that stoppers which are wider than they are long can only enter said annular recess right side up or upside down, a portion of said annular recess at the top of the inclined rotatable member not being covered by said cover means and said annular recess being shaped such that stoppers supported in said annular recess with their top sides down remain in said annular recess as they are raised with the rotation of said inclined rotatable member while stoppers positioned otherwise in said annular recess fall from said annular recess at the uncovered top portion of the inclined rotatable member under the effect of gravity.
