Device for Orienting Bulk-Fed Tubular Preforms
First Claim
1. An orientation device for orienting tubular preforms delivered in bulk by feed means, wherein it comprises:
- two continuous endless conveyors positioned side by side and each respectively having two strands which run substantially parallel to one another and which are separated from one another horizontally by a distance greater than the longest transverse dimension of the preforms, the preform feed means being situated above these two endless conveyors and near one of their ends, these two conveyors being driven by drive means in opposite directions to one another so as to cause those of the preforms which arrive crosswise on the endless conveyors to pivot and drop, oriented longitudinally, into the space between the two endless conveyors, andan endless collecting belt for collecting the preforms running under the aforementioned two endless conveyors and parallel thereto to collect the preforms and move them along, lying down longitudinally aligned one after the other.

Abstract
A device for orienting tubular preforms which are fed in bulk by a supply device, including two continuous endless conveyors which are disposed side by side and which are equipped respectively with two parallel lines which are separated horizontally from one another by a distance that is greater than the largest cross-sectional dimension of the preforms. According to the invention, the preform-supply device is disposed above one end of the two conveyors. The two conveyors are moved by drive device in opposing directions in order to pivot any preforms that arrive positioned sideways across the conveyors and to drop the longitudinally-oriented preforms into the space between the two conveyors. The orienting device also includes an endless belt for collecting preforms, which extends beneath the two conveyors parallel thereto and which is used to collect and move the horizontally-laid longitudinally-aligned preforms one after the other.
