Star wheel conveyor for conveying containers in a beverage filling system

A star wheel conveyor for conveying containers in a beverage filling system, comprising:

• a conveyor segment rotatable about a central axis of rotation and at least one pair of pocket arms directed outward with respect to the axis of rotation for forming a pocket that at least partially receives a container to be conveyed, wherein each pocket arm is arranged on the circumference of the conveyor segment and is pivotable about a pivot axis oriented substantially parallel to the axis of rotation,
• wherein the pocket arms engage with an adjustment part, which is arranged on the conveyor segment and is radially displaceable with respect to the axis of rotation, such that a pocket width of the pocket is adjustable by displacing the adjustment part in a radial direction,
• wherein the conveyor segment comprises a seal which provides sealing in the radial direction between a pocket-forming region of the pocket arms and/or of a punch, which region is present radially outside the seal, and a conveyor segment interior which is present radially inside the seal,
• wherein the adjustment part, interaction elements, at least one disk segment, a guide shoulder, a punch guide shoulder, a guide groove and/or a punch guide groove are arranged inside the conveyor segment,
• wherein the seal is a seal running around the circumference of the conveyor segment and/or the seal is a diaphragm seal and/or a bellows-type seal,
• wherein the seal comprises at least one boot region and/or one bellows region, and
• wherein the seal extends entirely over the circumference relative to the axis of rotation.
