Abstract
Official abstract text for this publication.
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 the plastic preforms along a predetermined transport path. The apparatus has at least one sensor device that detects at least one measured value that is characteristic of at least one of the two drive devices, and a control device that is designed to control the drive device for moving the holding elements as a function of this characteristic measured value.

Opening claim text (preview).
The invention claimed is: 1. An apparatus for heating plastic preforms, comprising 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, comprising 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, wherein the second transport device has a plurality of holding elements for holding the plastic preforms and 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 the apparatus comprises a drive device for moving the holding elements in a longitudinal direction of the plastic preforms, and the apparatus has at least one drive device for driving at least one transport device, wherein the apparatus has at least one sensor device adapted to detect at least one measured value that is characteristic of at least one of the two drive devices, and a control device adapted for controlling the drive device for moving the holding elements as a function of this characteristic measured value. 2. The apparatus as claimed in claim 1 , wherein the sensor device is adapted to detect at least one measured value that is characteristic of a torque of the at least one drive device. 3. The apparatus as claimed in claim 1 , wherein the drive device has a guiding cam adapted for moving the holding elements, which guiding cam extends, at least in sections, along the transport path of the holding elements. 4. The apparatus as claimed in claim 3 , wherein the drive device has an actuation device adapted for moving the guiding cam. 5. The apparatus as claimed in claim 1 , wherein the apparatus has a first drive device for driving the first transport device and a second drive device for driving the second transport device. 6. The apparatus as claimed in claim 1 , characterised in that at least one drive device for driving at least one transport device includes a servo motor. 7. The apparatus as claimed in claim 1 , wherein a relative position of the recesses of the first transport device can be changed in the circulating direction of the first transport device relative to a position of the holding elements in respect of the transport path. 8. The apparatus as claimed in claim 1 , wherein the apparatus has a processor device adapted to determine, from at least one characteristic value of a plastic preform, an offset between the two drive devices. 9. The apparatus as claimed in claim 1 , wherein said drive device is adapted to be deactivated for moving the holding elements during the on-going machine operation. 10. A method for heating plastic preforms, wherein the plastic preforms are transported in a recess of a first transport device and are taken over by a second transport device in a predetermined take-over position and are transported by said second transport device by holding elements that hold the plastic preforms along a predetermined transport path, and are heated, at least temporally, during the transport along the transport path by at least one heating device, wherein at least one drive device drives at least one transport device and the holding elements are moved in the longitudinal direction of the plastic preforms by a further drive device, wherein at least one measured value that is characteristic of at least the drive device is detected and the further drive device is controlled as a function of this measured value. 11. The method as claimed in claim 10 , wherein the characteristic measured value is a measured value that is characteristic of a torque of the drive device. 12. The method as claimed in claim 10 , wherein the measured value is continuously detected and/or is compared with a reference value. 13. The apparatus as claimed in claim 8 , wherein the characteristic value is a neck geometry of the plastic preform. 14. The apparatus as claimed in claim 5 , wherein the first drive device and the second drive device are adapted to be controlled independently of each other. 15. The apparatus as claimed in claim 1 , wherein the first transport device and the second transport device are adapted to be decoupled from each other with regard to their transport movements and/or can be decoupled at least at times. 16. The apparatus as claimed in claim 1 , wherein the apparatus comprises a control device for controlling the two drive devices, which drive device is adapted to control at least one of the two drive devices also on the basis of a parameter that is characteristic of a geometry of the plastic preforms. 17. The apparatus as claimed in claim 1 , wherein the control device is adapted to stop the movement of the holding elements upon detection by the at least one sensor device of a measured value characteristic of a fault, so that a transfer of the plastic preforms from the first transport device to the second transport device will not occur. 18. The apparatus as claimed in claim 1 , wherein the control device is adapted to adjust or correct an offset between the recesses of the first transport device and the holding elements of the second transport device.
