Device for the arrangement, alignment and correctly positioned feed of articles in particular having elongated shape

摘要

A feed apparatus for elongated articles comprises a pair of endless helical springs having parallel spaced-apart reaches defining a generally horizontal transport path. The elongated elements are continuously displaced in a direction from an upstream end of the reaches to a downstream end thereof. Elongated articles such as gelatin capsules are loaded in random fashion onto the reaches at the upstream end so that at least some of these articles come to lie in the trough defined between these reaches, that is aligned parallel to the transport direction. The misaligned capsules fall off the upper reaches onto a return transport mechanism which automatically transports them back to the upstream end of forward transport mechanism.
