Low power consumption machine for blow-moulding containers

摘要

Machine for forming containers (3a), comprising a unit (2) for extruding tubes (3) made of plastic, associated with an electric extrusion motor (200), a blowing unit (5) associated with an electric blowing motor (500), a mould (4) for containing the containers (3a), formed by two half-moulds (4a,4b) movable, upon operation of an associated electric mould motor (400), in a longitudinal direction X-X, the unit formed by the mould (4) and by the associated mould operating motor (400) being displaceable, upon operation of an electric displacement motor (300), in a transverse direction (Y-Y) from a first position substantially aligned with the extrusion unit (2) into a second position substantially aligned with the blowing unit (5) and vice versa, comprising at least one base power supply/recovery module (2000) and at least one first control module (2300) connected to said displacement motor (400) for controlling the acceleration/deceleration thereof.

1. A Machine for forming containers (3a) comprising:
a unit (2) for extruding tubes (3) made of plastic, associated with an electric extrusion motor (200), a blowing unit (5) associated with an electric blowing motor (500), a mould (4) for containing the containers (3a), formed by two half-moulds (4a, 4b) movable, upon operation of an associated electric mould motor (400), in a longitudinal direction (X-X), the unit formed by the mould (4) and by the associated mould operating motor (400) being displaceable, upon operation of an electric displacement motor (300), in a transverse direction (Y-Y) from a first position substantially aligned with the extrusion unit (2) into a second position substantially aligned with the blowing unit (5) and vice versa, and programming devices (1000) connected to the motors (200,300,400,500,600) wherein the programming devices (1000) are associated with a power supply/recovery apparatus comprising at least one base module (2000) and at least one first control module (2300) connected to said displacement motor (400) for controlling the acceleration/deceleration thereof during the displacement stroke and the recovery of energy during deceleration of each stroke and in that said machine programming devices (1000) comprise a synchronizer (2000e) connected to a fast transmission channel (2000d) arranged between the said synchronizer and the control module (2300) of the power supply and recovery apparatus.
