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.
Claims14
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, wherein each mould includes mould parts movable relative to one another to produce compression of the doses, the compression moulding machine further including a hydraulic circuit responsible for the relative movement of the mould parts;
- 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;
- wherein the first predetermined position is disposed at the compression moulding machine;
- wherein the first sensor is a pressure transducer that senses a pressure parameter representative of an operation of the hydraulic circuit;
- and
- wherein, for the pressure parameter, a trend is derived with respect to the rotation of the moulding carousel.

- 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,
- wherein the first sensor is a pressure transducer that senses a pressure parameter representative of an operation of the hydraulic circuit, and
- wherein, for the pressure parameter, a trend is derived with respect to the rotation of the moulding carousel.
