Abstract

A separator device for preforms with an alignment device for handling incorrectly aligned preforms, wherein the separator device is a roller sorter with two transport rollers rotating in opposite directions to one another, between which rollers preforms are transported in a conveying direction, in a suspended manner and with an intended alignment. The alignment device has a rotating body mounted rotatably about an axis, which body is arranged above the roller sorter so that the rotating body projects into the movement path of incorrectly aligned preforms. The rotating body is designed to exert an alignment force on incorrectly aligned preforms. The rotating body also projects into the movement path of the preforms with the intended alignment and is therefore designed and arranged to exert an alignment force only on incorrectly aligned preforms.

Dependent claims

A separator device for preforms, comprising:

an alignment device for dealing with misaligned preforms;
and a roller sorter with two conveying rollers rotating in opposite directions and between which the preforms are transported in a conveying direction while suspended with a proper alignment, wherein the alignment device comprises a rotating body supported rotatably around an axis, the rotating body being arranged above the roller sorter so that the rotating body projects into a path of movement of misaligned preforms, wherein the rotating body is configured to exert an aligning force on the misaligned preforms that are not suspended in the proper alignment between the conveying rollers, wherein the rotating body also projects into a path of movement of preforms that are suspended in the proper alignment between the conveying rollers and is configured and arranged so as to exert an aligning force only on the misaligned preforms.

Dependencies are inferred from the claim text.
