Preform conveying device

Abstract

An object of this invention is to provide a preform conveying device of high production efficiency under the technical theme of aligning the plurality of preforms in single rows at high speed, while eliminating contact of individual preforms with other preforms and minimizing the chances of contact with device parts. In a state in which a plurality of preforms are aligned vertically and laterally, preforms are received in a manner partitioned in vertical row units, and by putting a conveying line, formed along the direction of a vertical row of preforms, in an inclined orientation in which the downstream side is raised, positioning the upstream end of the conveying line above a preform receiving part, and moving the vertical row unit of preforms that is positioned along the conveying line in the vertical row direction at substantially the same speed as the conveying speed of the conveying line, the respective preforms of the vertical row unit are transferred in a state in which each is sandwiched by the conveying line and this is carried out successively for each vertical row unit to supply the plurality of preforms to a blow molding machine or other subsequent process side upon aligning them in single rows.
