Apparatus for forming plastic material preforms into plastic material containers with decoupled drives

A method for forming plastic material preforms into plastic material containers, wherein the plastic material preforms are transported with a transport device along a predetermined transport path, wherein this transport device comprises a plurality of transport devices for transporting the plastic material preforms, wherein a heating device heats the plastic material preforms and a forming device which is arranged along the transport path of the plastic material preforms after the heating device forms the plastic material preforms into the plastic material containers by acting upon a flowable medium, wherein the apparatus has a first transport device which feeds the plastic material preforms individually to the heating device, Wherein the heating device has a second transport device which transports the plastic material preforms during their heating,

• wherein
• the first transport device has a first drive device and the second transport device has a second drive device, said process comprising the step of controlling;
• the first drive device and the second drive device independently of each other at least at times,
• wherein the first transport device is driven at a different transport speed with respect to the second transport device, and the first transport device is stopped while the second transport device is in continued operation,
• wherein the first drive device of the first transport device is only moved when a transfer of the plastic material preforms has to take place, so that the first transport device acts as a transport lock, wherein
• the transport device has a third transport device which is configured to transport the plastic material preforms from the heating device to the forming device, and the third transport device has a drive device which is configured to be controllable independently of the drive device of the first transport device and/or the drive device of the second transport device,
• wherein the forming device is a blow moulding machine which is configured to transform the plastic material preforms into plastic material containers by acting upon a gaseous medium,
• wherein the transport device has a fourth transport device which is a blowing which is assigned to the forming device, and a plurality of forming stations is arranged on the blowing wheel,
• wherein the forming stations have stretching bars,
• wherein the apparatus has a sorting device which is configured to sort and align the plastic material preforms from a preform chute, and at least one sensor device which is configured to detect faults in the transport of the plastic material preforms wherein in response to such an error of the transport device, a transport drive can be slowed down or switched off.
