Low power consumption machine for blow-moulding containers

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.
