摘要:
Method for controlling a method for the manufacture of a container by stretch-blow-moulding of a plastic preform (2) in a machine (1) comprising a mould (26), the preform (2) having a body (3), a neck (4) opening at one end of the body (3) and a bottom (5) closing the body (3) at another end thereof, the manufacturing method comprising the operations involving: - heating the preform to a predetermined temperature in a thermal conditioning oven (10); - introducing the preform (2) into the mould (26); - moving a stretching pin (28) so as to stretch the preform (2); this control method involving a step that consists in determining the position of impact (P0r) of the stretch pin (28), namely the position it occupies at the moment at which it reaches the bottom (5) of the preform (2) during its movement.
摘要:
The invention relates to a method for detecting an anomaly during the forming of containers (2) from blanks (3) made of a plastic material inside a forming machine (6) comprising a plurality of forming stations, each station being connected to a tank (24) for recovering fluid which is under pressure during the recovery operation, said method comprising the operations of: continuously measuring the pressure (PR) of the fluid in the tank (24); comparing said pressure (PR) with a pre-determined theoretical pressure in order to detect any so-called critical deviation (E) higher than a pre-determined threshold value; and generating a warning as soon as a critical deviation (E) is determined.
摘要:
The present invention relates to a machine (10) for sterilizing plastic preforms for the manufacture of containers, characterized in that the machine (10) comprises a device (50) for detecting the fouling of at least one sterilizing-fluid conveying line (38) extending fully or partially through an injection nozzle (30), said detection device (50) comprising at least emitter means (52), receiver means (56) and a control unit (70) for determining the degree of fouling of said conveying line (38) by comparing the intensity of the light radiation emitted at one (40, 48) of the ends thereof with that received at the other (40, 48) of the ends thereof.
摘要:
A machine for filling containers (2) is provided with a plurality of handling units (13), each of which has a filling valve (20) and a filling head (24), which defines, together with the filling valve (20), a supply path for a pourable product into a relative container (2), is coupled in an angularly fixed manner to a support device (32) for receiving and retaining a relative container (2), and is coupled, further, in a rotary and fluid-tight manner to the filling valve (20) by interposing a mechanical gasket (38) having a first ring (40) angularly fixed to the filling valve (20) and a second ring (39) angularly fixed to the filling head (24); a washing device (43) being provided for washing the mechanical gaskets (38) of the handling units (13) so as to remove the residuals of the pourable product from the mechanical gaskets (38) itself.
