Greifer für Plastikflaschen

摘要

A resin bottle 16 has an opening at its top end in which a thread 16a is formed, and also has a neck including a cylindrical portion 16b and a flange 16c which are disposed below the opening. An intermediate wheel 8 is disposed between a filler 6 which fills the resin bottle 16 and a capper 10 which caps the filled bottle 16. The intermediate wheel 8 is provided with a plurality of circumferentially spaced grippers 22 each gripping the cylindrical portion 16b of the resin bottle 16, and rotatively conveys the bottle while it is suspended by gripping the neck of the resin bottle. A support 32 is disposed above each gripper 22 for abutment against the opening of the resin bottle 16, whereby in the event the bottom of the bottle 16 is swung radially outward, the opening which is located above the cylindrical portion 16b that is gripped by the gripper 22 is urged by the support 32 from the radial inside, thus allowing the bottle to be maintained in its upright position.
