The invention relates to blowing equipment () that uses a pressurised fluid for blowing vessels from preforms of a thermoplastic material and including a body () and a neck (), wherein said equipment comprises a blowing mould () with a moulding cavity () in which the body () of a preform () can be placed, said mould () including an upper surface () from which protrudes the neck () of a preform () once the body () of said preform () is placed in the cavity (), and wherein said equipment () also includes a nozzle () with an end () shaped so as to be placed in functional sealed relation with the protruding neck () of the preform (). The end () of the nozzle () is connected to a means () for degassing the blowing fluid, capable of bearing tightly on the upper surface () of the mould () so as to define an inner volume () in which the blowing fluid blown under pressure into the preform () can be discharged after the preform () blowing operation. The equipment includes a degassing means capable of expanding the blowing fluid around the blowing cavity, wherein said means includes a plurality of channels () arranged around said blowing cavity, said channels () having one side opening into the inner volume of the degassing means () while the other side gives into an annular channel () for discharge into the atmosphere.

Equipment for blowing vessels of a thermoplastic material

The invention relates to a fluid flow control assembly for a container blowing machine, comprising: a blow pin (); a plurality of pipes for the circulation of a blowing fluid, which enable the blowing fluid to flow between at least one blowing fluid source, at least one fluid discharge outlet and the aforementioned blow pin (); and valves which can control the flow of the blowing fluid inside the plurality of fluid circulation pipes. The invention is characterized in that the valves are all placed on the front of a body () housing the blow pin ().

Fluid flow control assembly for a container blowing machine and machine comprising one such assembly

The invention concerns a device for loading () or unloading () preforms () comprising a neck () on a transporting element () which includes a device () for individually gripping one preform () by its neck, the loading or unloading device comprising: means for dispensing () preforms which include means for individually receiving () each preform, the trajectory of the receiving means and the trajectory of the gripping means, in planar projection, being tangent in at least one intersecting point (P, P) wherein the preform () being in a gripping position, the neck () of the preform () is vertically arranged opposite the gripping member; means for synchronizing the movement of the receiving means relative to the movement of the gripping member. The invention is characterized in that the trajectory of the receiving means and the trajectory of the gripping member are superimposed along at least one intersecting line (P-P, P-P).

Device for loading or unloading containers comprising a neck on a transporting element

A moulding device for the production of containers in thermoplastic material, by blowing or blow-drawing, including a mould with two mould halves mutually mobile and provided with a locking device with two lock elements extending over the total height of the respective mould halves and provided with a number of projecting fingers in catches spaced at intervals, one lock element being fixed on one mould half and the other lock element sliding on the other mould half under the action of an actuator device.
