1. An apparatus for transporting closure elements, said apparatus comprising a supplying device, and a cap detecting system, wherein said supplying device is configured to transport a plurality of caps prior to application of each of said caps onto a corresponding container from a plurality of containers, wherein each of said caps has a feature that defines an angular orientation of said cap, wherein said angular orientation results from rotation of said cap about an axis defined by a line normal to a surface of said cap, wherein said closure element is configured to engage an opening of a container that is in an open state, thereby transforming said container into a container that is in a closed state, wherein each of said caps from said plurality of caps has a corresponding random angular orientation, wherein said supplying device is configured to hold each of said caps in said corresponding random angular orientation, wherein said supplying device is configured to transport each of said caps along a transport path, wherein during transport along said transport path, each of said caps retains said corresponding random angular orientation, and wherein said cap detecting system is placed along said transport path to record said corresponding random angular orientations prior to placement of said caps on corresponding containers, wherein, in said open state, a mouth of said container is open so that liquid can pass from outside said container into an interior of said container, wherein, in said closed state, said mouth is closed so that liquid trapped inside said container by a closure element can no longer pass from said interior of said container to outside said container as a result of said mouth having blocked by said closure element, whereby, by the time a closure element is first placed on a corresponding container, said random angular orientation of said closure element has already been recorded by said cap detecting system, and whereby said container can be rotated to a correct position corresponding to said random angular orientation before said closure element is first applied to said container, whereby containers that are in an open state are transformed into said closed state by application of said closure cap, wherein said closure cap has a first side on which said feature is present, and a second side opposite said first side, wherein said supplying device comprises a first transport wheel and a second transport wheel, wherein said first transport wheel and said second transport wheel rotate in opposite directions, wherein said first transport wheel receives said closure element from a conveyor and engages said closure element with said first face facing outward, said second side facing inward, and said feature having a first angular orientation, wherein said first transport wheel transports said closure element along a first circumferential path, wherein said first transport wheel transports said closure element towards said second transport wheel along said first circumferential path, wherein said first transport wheel engages said closure element so that said first side is viewable by said cap detecting system, wherein at a first point in said first circumferential path, said first transport wheel transports said closure element past said cap detecting system for inspection of said feature and determination of said angular orientation of said closure element based on said inspection, wherein at a second point in said circumferential path, said first transport wheel provides said closure element to said second transport wheel, wherein said second transport wheel receives said closure element at said angular orientation and transports said closure element with said angular orientation unchanged, wherein said second transport wheel transports said closure element received from said first transport wheel toward a container along a second circumferential path, wherein said second transport wheel engages said closure element so that said first side is facing said second transport wheel and said second side is facing outward, wherein, at a first point on said second circumferential path, said second transport wheel receives said closure element from said first transport wheel, wherein at a second point on said second circumferential path, said second transport wheel places said closure element on a container that has been rotated to receive said closure element based on data provided by said cap detecting system from inspection of said closure element while said first closure element was engaged by said first transport wheel, and wherein said second transport wheel places said closure element on said container with said first face facing outside said container. |
