摘要:
The invention concerns a device for loading (10) or unloading (58) preforms (12) comprising a neck (20) on a transporting element (14) which includes a device (28) for individually gripping one preform (12) by its neck, the loading or unloading device comprising: means for dispensing (32, 42) preforms which include means for individually receiving (42) 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 (P3, P4) wherein the preform (12) being in a gripping position, the neck (20) of the preform (12) 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 (P3-P1, P2-P4).

The invention relates to blowing equipment (1) that uses a pressurised fluid for blowing vessels from preforms of a thermoplastic material and including a body (3) and a neck (6), wherein said equipment comprises a blowing mould (5) with a moulding cavity (4) in which the body (3) of a preform (2) can be placed, said mould (5) including an upper surface (7) from which protrudes the neck (6) of a preform (2) once the body (3) of said preform (2) is placed in the cavity (4), and wherein said equipment (1) also includes a nozzle (8) with an end (9) shaped so as to be placed in functional sealed relation with the protruding neck (6) of the preform (2). The end (9) of the nozzle (8) is connected to a means (12) for degassing the blowing fluid, capable of bearing tightly on the upper surface (7) of the mould (5) so as to define an inner volume (13) in which the blowing fluid blown under pressure into the preform (2) can be discharged after the preform (2) 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 (28) arranged around said blowing cavity, said channels (28) having one side opening into the inner volume of the degassing means (12) while the other side gives into an annular channel (29) for discharge into the atmosphere.

The invention relates to a station for the stretching/blowing of preforms having an upward-facing open end. The inventive station (100) comprises a bracket (4000) that supports a blow mould, a stretch rod (2700) and means for controlling the movements of the stretch rod (2700). The aforementioned control means comprise: (i) an actuator, and (ii) a roller (4700) and a speed control cam (200), said roller (4700) coming into contact with the speed control cam (200) as the stretch rod (2700) enters the blow mould, thereby controlling the speed with which the stretch rod (2700) enters the blow mould. The invention is characterised in that the speed control cam (200) is disposed below the base (800) of the blow mould.
