Abstract
An inverter device is intended to operate on half-moulds which advance in alternate sequence on a conveyor line. The inverter device has inverter sets on both sides of the conveyor line, each of which comprises a fixed unit and a movable unit with respective engagement formations capable of engaging the half-moulds by the effect of a general approaching movement towards the conveyor line. Having achieved engagement of the half-moulds the movable unit is then driven to rotate by means of a mechanism actuated by a cam so as to obtain the desired inverting movement. The same configuration can be utilised equally well for causing book-like mould closure movement of adjacent half-moulds as for causing mould-opening motion of superimposed half-moulds.

In an inverter device capable of acting on pairs of complementary moulds which advance on a conveyor line, whereby respectively to invert a mould and close it over the complementary mould and to invert a mould disposed on said complementary mould to open it, said device having engagement formations capable of engaging said moulds laterally thereof by making an approaching movement towards said conveyor line, the improvement comprising
- at least one inverter set mounted on a cyclic movement element on each side of said conveyor line such that said at least one inverter set can follow the movement of said complementary mould on said conveyor line in a synchronised manner,
- a fixed unit and a movable unit on said at least one inverter set, said fixed and movable unit being provided with respective engagement formations capable of selectively engaging at least one of said complementary moulds of said pair by an approaching movement of said inverter set towards said conveyor line, and
- actuating means associated with said movable unit operating to cause a pivoting movement of said movable unit between a first position in which said engagement formation associated with said movable unit is substantially coplanar with and alongside the engagement formation of said fixed unit at a distance substantially corresponding to the distance which separates said two half-moulds and a second position in which the engagement formation of said movable unit is superimposed over the engagement formation of said fixed unit;
- said actuating means being actuated as a function of the motion of said inverter set following that of said complementary moulds, caused by said cyclic movement element.
