Abstract
A line for the continuous cycle production of plastic objects comprises: an extruder configured to deliver a flow of plastic fluid; a compression moulding machine including a rotating moulding carousel and a plurality of moulds to form an ordered succession of objects from corresponding doses; a transfer apparatus configured to feed the doses individually to the compression moulding machine; a conveyor; a first sensor configured to detect a first diagnostic signal; a control unit programmed to capture the first diagnostic signal.

A line for the continuous cycle production of plastic objects, comprising:
- an extruder configured to receive solid plastic material in raw form and to feed out a flow of plastic fluid;
- a compression moulding machine including a rotating moulding carousel and a plurality of moulds to form an ordered succession of objects from corresponding doses;
- a transfer apparatus configured to obtain an ordered succession of doses from the flow of plastic fluid and to feed the doses individually to the compression moulding machine;
- a conveyor configured to receive the objects individually and to transport them in the same ordered succession;
- a first sensor configured to detect a first diagnostic signal and located at a first predetermined position in the line;
- and
- a control unit configured to generate a synchronization signal representing an operating configuration of the line in real time and programmed to capture the first diagnostic signal synchronously relative to the synchronization signal.
A method for the continuous cycle production of plastic objects, comprising the following steps:
- extruding a solid plastic material and generating a flow of plastic fluid;
- forming an ordered succession of doses from that flow of plastic fluid;
- inserting the doses in corresponding moulds integral with a rotating moulding carousel;
- compression moulding an ordered succession of objects by compressing the doses in the moulds;
- transporting the objects away from the moulding carousel one by one while keeping them in the same ordered succession;
- detecting a first diagnostic signal through a first sensor located at a first predetermined position in the line;
- generating a synchronization signal representing an operating configuration of the line in real time;
- and
- capturing the first diagnostic signal synchronously relative to the synchronization signal.

- a compression moulding machine including a rotating moulding carousel and a plurality of moulds to form an ordered succession of objects from corresponding doses;
- a transfer apparatus configured to obtain an ordered succession of plastic quantities from the flow of plastic fluid and to feed the doses individually to the compression moulding machine;
- a conveyor configured to receive the objects individually and to transport them in the same ordered succession;
- a first sensor configured to detect a first diagnostic signal and located at a first predetermined position in the line and
- a control unit configured to generate a synchronization signal representing an operating configuration of the line in real time and programmed to capture the first diagnostic signal synchronously with respect to the synchronization signal,
- wherein the control unit receives an analogue signal representing a time trend of the first diagnostic signal, generates a digital representation of the analogue signal and processes the digital signal responsive to the synchronization signal.
