Abstract:
A method of conveying plastics material pre-forms includes the plastics material pre-forms supplied to a conveying device by a supply device. The conveying device has a first roller body and a second roller body. The plastics material pre-form is conveyed between these roller bodies. A portion of the plastics material pre-forms is supported by the two roller bodies. A further portion of the plastics material pre-forms passes through between the roller bodies. At least one first value characteristic of a state of occupation of the plastics material pre-forms is detected by a first measuring instrument. A second value characteristic is detected by a second measuring instrument downstream of the first measuring instrument in the conveying direction of the plastics material pre-forms. A setting variable of the supply device or the conveying device is controlled on the basis of the two values.
Abstract:
The invention relates to a method of conveying plastics material pre-forms, wherein the plastics material pre-forms are supplied to a conveying device by means of a supply device and the conveying device has a first roller body and a second roller body which extend substantially parallel to each other, and the plastics material pre-form is conveyed between these roller bodies, wherein a portion of the plastics material pre-forms is supported by the two roller bodies and wherein a further portion of the plastics material pre-forms passes through between the roller bodies. According to the invention at least one first value characteristic of a state of occupation of the plastics material pre-forms is detected by means of a first measuring instrument and a second value characteristic of the state of occupation of the plastics material pre-forms is detected by means of a second measuring instrument which is situated downstream of the first measuring instrument in the conveying direction of the plastics material pre-forms, and at least one setting variable of the supply device or the conveying device is controlled on the basis of the two values.
