Apparatus for orienting containers

摘要

A container orienting apparatus suitable for flasks and other non-cylindrical containers comprising a pair of continuously moving counter-rotating parallel belts for engaging opposite sides of the finish and/or neck of each container and for rotating each container a predetermined amount by changing the relative speeds of the belts for a predetermined time period. The amount of rotation necessary to rotate each container to a common second orientation is determined by a programmable controller responsive to orientation sensors which determine which one of a number of discrete first orientations each container is in prior to engagement by the belts. The controller contains in memory a plurality of predetermined instruction sets corresponding to the various possible container orientations and the amount of rotation which is required to achieve a predetermined common second orientation. Each instruction set comprises that set of control signals which must be applied to the motors and clutches affecting belt motion to achieve a desired orientation.
