BLOW MOULDING MACHINE WITH AUTOMATICALLY ACTUATED BASE COUPLING
Apparatus for transforming plastic parisons into plastic containers includes a transforming station having a blow mould within which plastic parisons can be expanded by application of a gaseous medium. The blow mould has a base part arranged releasably on a support. The transforming station has at least one first connector for supplying a flowable temperature control medium to the transforming station, and this supply of the temperature control medium can be disconnected via the connector. The fastening mechanism has a release element which is movable in a predetermined straight direction. By displacement of this release element into a first predetermined position fastening of the base part on the support is releasable and by a displacement of this release element into a second predetermined position the base part can be fastened on the support.
RECEPTACLE CONVEYING AND COOLING APPARATUS, A METHOD OF OPERATING SUCH A RECEPTACLE CONVEYING AND COOLING APPARATUS AND A RECEPTACLE TREATMENT MACHINE HAVING SUCH A RECEPTACLE CONVEYING AND COOLING APPARATUS
There is described a conveying and cooling apparatus (6, 6) for conveying and cooling receptacles (2) comprising a conveying device (25) for advancing receptacles (2) along a conveying path (P1), a cooling device (28, 28) for cooling the receptacles (2). The cooling device (28, 28) comprises a supply unit adapted to supply a cooling medium, a plurality of advancing injection nozzles (45) adapted to be in fluid connection with the supply unit and for directing a cooling medium onto the receptacles (2) and a plurality of valve members (46), each one associated to one respective injection nozzle (45) and adapted to selectively open or close the fluid connection between the respective injection nozzle (45) and the supply unit (40, 81).
Blow moulding machine with automatically actuated base coupling
Apparatus for transforming plastic parisons into plastic containers includes a transforming station having a blow mold within which plastic parisons can be expanded by application of a gaseous medium. The blow mold has a base part arranged releasably on a support. The transforming station has at least one first connector for supplying a flowable temperature control medium to the transforming station, and this supply of the temperature control medium can be disconnected via the connector. The fastening mechanism has a release element which is movable in a predetermined straight direction. By displacement of this release element into a first predetermined position fastening of the base part on the support is releasable and by displacement of this release element into a second predetermined position the base part can be fastened on the support.
METHOD FOR MANUFACTURING RESIN CONTAINER AND BLOW MOLDING METHOD
A temperature adjustment mold for a blow molding apparatus provided with at least an injection molding unit that injection-molds a preform made of a resin and having a bottomed shape, a temperature adjusting unit that adjusts a temperature of the preform manufactured by the injection molding unit, and a blow molding unit that blow-molds the preform to manufacture a resin container, the temperature adjustment mold including a cavity mold that accommodates the preform, and an air introduction member that includes a fitting core and a rod member with a multiple-tube structure to form at least three concentric air flow paths.
Method and device for producing containers
A method for producing containers (10) filled with liquid, more particularly drinks containers, wherein plastic preforms are shaped into plastic containers (10) by means of a shaping device (2), these plastic containers are transported to a filling device (4) and are filled with a liquid by means of this filling device, wherein, on their transport path between the shaping device (2) and the filling device (4) the containers (10) are cooled, at least partly, by being charged with a liquid medium. According to the invention the containers are transported, at least during filling, within a clean room (20) which is delimited from an environment by means of a sealing device (62).
GAS-ASSISTED BASE BLOW OFF METHODS FOR BLOW MOLDING APPLICATIONS
This disclosure provides a method of manufacturing a polymer container according to a blow molding or stretch blow molding process, in which the base of the blow mold has at least one orifice for pressurized gas to enter the blow mold through the base. Introducing pressurized gas through the orifice in the blow mold base provides cooling assistance within the gas mold, much earlier than the cooling using conventional methods, which can reduce or eliminate the need for any post mold cooling. This method has been found to be applicable to non-hot fill application bottle and container manufacture.
Method and apparatus for forming plastic preforms into plastic containers with four pressure levels and bottom cooling
A method and device for forming plastic preforms into plastic containers has a plurality of forming stations each having application devices which apply a flowable medium at least a first pressure level, a second pressure level, a third pressure level and a fourth pressure level respectively, wherein the second pressure level is higher than the first pressure level, the third pressure level is higher than and the second pressure level and the fourth pressure level is higher than the third pressure level and wherein at least at times a bottom area of the plastic preform and/or plastic container is applied with the flowable medium.
Blow moulding machine with cooling of the base in the stabilization phase
In a blow moulding machine for the production of plastics material containers, during a blow mould procedure, the container to be expanded is supplied with blow moulding air from a first gas preparation device on the one hand or from a second gas preparation device on the other hand. During this procedure a cooling of the base of the container is additionally carried out.
