An apparatus for blow molding plastic containers, particularly bottles, including a blow molding carousel, which can rotate about a main rotation axis and is functionally connected, at a first transfer station and at a second transfer station, to a line for feeding the preforms and to a line for unloading the bottles, the blow molding carousel supporting, at its peripheral region, a plurality of forming units arranged around the main rotation axis. Each forming unit has a mold that defines a first and a second forming cavity and is formed by two half-mold parts, which can move with respect to each other to pass between an open position for feeding the preforms and for unloading the bottles and a closed position, in which it defines at least one forming cavity.

Apparatus for blow molding plastic containers, particularly bottles

A device for transferring objects, in particular parisons () or bottles (), has a carousel () able to rotate about a predetermined axis (X), an object () pick up element (), a supporting arm () for the pick up element () connected to the carousel (), the pick up element () having at least three degrees of freedom relative to the carousel (), a cam () for guiding the arm () and the pick up element (), having a predetermined number of tracks (), for moving the pick up element () along a predetermined path (P); the cam () has a fixed portion () and at least one removable portion () connected to the fixed portion (), the removable portion () having a predetermined profile and there being the possibility of substituting it with other removable portions having a different profile to the portion ().

Transfer device

A plant for blow-molding plastic containers (), particularly bottles, from respective parisons () is equipped with a plurality of molding units (), each having at least two respective cavities () for blow-molding respective containers (), and with a transfer device () for transferring the parisons () from a flexible feed conveyor () to the respective molding cavities (). The transfer device () is connected to the flexible feed conveyor () at a transfer station (), where the spacing (P) of the parisons () is equal to the distance (D) between the longitudinal axes () of the molding cavities () of one molding unit ().

Plant for blow-moulding plastic containers, particularly bottles

A plant for blow-moulding plastic containers (), particularly bottles, from respective parisons () comprises at least one moulding unit () composed of two half-moulds (), each mobile relative to the other half-mould () between a position of opening and a position of closing at least two cavities () for blow-moulding containers (); the two half-moulds () being oriented in such a way that they close in a closing plane () that is substantially tangent to the feed path (P) of the moulding unit ().

Moulding unit for a plant for blow-moulding plastic containers, particularly bottles

A molding unit for a plant for blow-molding plastic containers (), particularly bottles, from respective parisons () is equipped with an interchangeable mold () having at least one cavity () for blow-molding a respective container (), and at least two stretching rods () mobile along a predetermined line () to engage respective parisons () and to axially deform the parisons () themselves; the stretching rods () being selectively mobile according to the number and/or position of the molding cavities () of the mold () mounted on the molding unit at a given time.

Apparatus, comprising a rotating carousel and a plurality of handling elements supported by said carousel and movable in relation to said carousel, said handling elements being so shaped as to remove a container from a blow-moulding mould arrangement, wherein said apparatus further comprises a plurality of further handling elements associated with said handling elements, said further handling elements being so shaped as to deliver a dose of plastics to a compression-moulding mould arrangement, each of said further handling elements being fixed to a corresponding handling element.

Apparatuses and methods for manufacturing containers

An apparatus () for making plastic containers by blow-molding parisons comprises: a mold () having at least one molding cavity; a base () mounted over the mold (), forming at least one passage () connected to a high-pressure fluid source; a blow nozzle () forming at least one conduit and connected to a bottom face () of the base () to be positioned between the base () and the mold () in such a way that the conduit is in fluid communication with the passage () to receive the high-pressure fluid and convey it into the molding cavity; fastening means for coupling and uncoupling the blow nozzle () to and from the base (); at least one pin () protruding from the nozzle () to be inserted into a respective through hole in the base () with an end portion () of it positioned above a top face () of the base (); a fastening element () connected to the base () to be movable from an unlocked position, where it does not interfere with the pin (), to a locked position where it is inserted in an end groove () defined by the end portion () of the pin (), and vice versa.

Apparatus and a method for making plastic containers by blow-moulding parisons

Mold arrangement, comprising a blow-molding die arrangement arranged for receiving a preform and for expanding said preform to obtain a container, wherein a compression-molding die arrangement is associated with said blow-molding die arrangement, said compression-molding die arrangement being arranged for receiving plastics and for shaping said plastics to obtain a neck portion of said preform.

A moulding unit for a plant for blow-moulding plastic containers () from respective parisons () comprises: two half-moulds (), movable relative to each other between a position of opening and a position of closing at least one cavity () for blow-moulding a respective container (); and a locking device () for locking the two half-moulds () in the closed position, the locking device () comprising two first fastening elements () which are moved to, and normally held in, a locked position by at least one elastic actuating element ().

An apparatus comprises a blow-moulding mould arrangement arranged for expanding a preform to obtain a container, said blow-moulding mould arrangement comprising a die arrangement cooperating with a punch arrangement, the apparatus further comprising a compression-moulding mould arrangement comprising a further die arrangement cooperating with said punch arrangement for compression-moulding plastics to obtain said preform.
