An apparatus for conveying of plastics material pre-forms, with a plurality of holding devices which engage in apertures of the plastics material pre-forms and hold them, wherein these holding devices are movable along a pre-set conveying path, with a movement mechanism which has the effect that, in addition to the movement along the conveying path, the holding devices are also movable in a direction at a right angle to this conveying path. The apparatus has at least one detection device which is suitable for detecting a defective state of a plastics material pre-form held by a holding device, and at least one first removal apparatus arranged downstream along the conveying path of the at least one detection device and which—in reaction to a signal of the detection device—permits individual removal of a defective pre-form from the holding device.

A device for transporting plastic preforms to a stretch blow molding machine comprising a feeder device, which transports the plastic preforms to a separating device, which is arranged in transport direction upstream of the stretch blow molding machine, wherein the feeder device comprises a pneumatically actuable blocking device, which in a first position deblocks the path of transport for the preforms and in a second position blocks the path of transport for the plastic preforms, and wherein the blocking device is actuable by means of a cylinder. According to the invention, the valve for controlling the cylinder is arranged in the immediate vicinity of the cylinder.

An apparatus for heating plastic preforms includes a first transport device that transports the plastic preforms in a separated manner, wherein said first transport device has a plurality of recesses for receiving the plastic preforms, and a second transport device that takes over the plastic preforms transported by the first transport device and transports said plastic preforms along a predetermined transport path. The second transport device has a plurality of holding elements for holding the plastic preforms. The apparatus also includes at least one heating device that heats the plastic preforms transported by the second transport device, wherein at least the first transport device is a circulating transport device, wherein a relative position of the recesses of the first transport device in the circulation direction of the first transport device relative to a position of the holding elements in respect of the transport path can be changed.

摘要:
In an apparatus for the heating of plastics material pre-forms with a conveying device which conveys the plastics material pre-forms along a pre-set conveying path, at least one heating device moves with the plastics material pre-forms arranged on the conveying device, wherein the heating device comprises a receiving room that receives the plastics material pre-forms and that surrounds the plastics material pre-forms during heating thereof. A holding device holds the plastics material pre-forms. The plastics material pre-forms are conveyed through a clean room, the clean room surrounding the conveying path of the plastics material pre-forms. A moving device introduces the plastics material pre-forms into the receiving room and removes plastics material pre-forms from the receiving room. At least one portion of the moving device is arranged exterior the clean room. A sealing device seals the clean room from an exterior environment.
