摘要:
An apparatus (1) for producing sterile receptacles (2), comprising: a moulding unit (13) for moulding parisons (4) starting from granules of thermoplastic material; a stretch-blowing forming unit (3) which receives the parisons (4) from the moulding unit (13), the forming unit (3) having a plurality of forming stations (5) in each of which there is a mould (6) and a sterilisation device (12) so as to form and sterilise the corresponding parison (4).
摘要:
Stretch-blowing device (1) in aseptic conditions for a preform (100) made of thermoplastic material, comprising: a blowing nozzle (2) located at least partially in a controlled contamination environment (3) and applicable on the mouth (100a) of the preform (100) to inject compressed air into the latter; a stretching rod (5) slidably mounted within the blowing nozzle (2) so that a first portion (5a) thereof can penetrate inside the preform (100) through the mouth (100a); a linear motor (6) comprising a cylindrical stator (7) and a rotor (8) integrally connected to a second portion (5b) of the stretching rod (5); a box-shaped casing (9) formed by the stator (7) and by a plurality of walls (9a) that together define a chamber (10) for housing the rotor (8) and the second portion (5b) of the stretching rod (5), the housing chamber (10) being sealingly closed to the external environment, the linear motor (6) having at least one grooved surface (14, 15, 18) that faces the inside of the chamber (10) to facilitate the passage of a sanitising fluid introduced into the chamber (10).

摘要:
The invention relates to a method for carrying out a repositioning process for a device for producing beverage containers. In a working operation, the device produces plastic containers from plastic preforms by means of a shaping device, the produced plastic containers are transported to a filling device, and the containers are filled with a liquid, in particular a beverage, wherein the liquid is filled into the container at a temperature above 50 °C. At least the shaping device and the filling device are in data communication with each other at least temporarily, and a value which characterizes a repositioning status of the shaping device or the filling device is output and/or used in order to carry out the repositioning process of at least the shaping device or the filling device.

Method for cooling heated molds from a machine for molding containers. The invention relates to a method for cooling heated molds from a machine (10) for molding containers from thermoplastic material by stretch-blow molding hot preforms using at least one pressurized fluid. Said cooling method is characterized in that it comprises, in order to cool said molds (18), at least one cooling step that involves selectively feeding at least one cooling fluid into the molding cavity (16) of at least some of the molding units (12) that, after the carousel (14) has been stopped in order to immobilize said molding units at least during said cooling step, are located in a predetermined cooling region in which said molding units (12) are in a closed position.
