Abstract

A plant ( 10 ) for manufacturing containers ( 12 ) from thermoplastic preforms ( 16 ), the plant ( 10 ) including at least:—a first unit ( 12 ) for thermally conditioning the preforms ( 16 ) which includes a first vertical lateral face (F 1 ); and—a second unit ( 14 ) for shaping the containers ( 24 ) from the preforms ( 16 ) which have been thermally conditioned in the first unit ( 12 ), the second unit including a second vertical lateral face (F 2 ); characterized in that the plant ( 10 ) includes at least one robot ( 50 ) which faces the first vertical lateral face (F 1 ) and the second vertical lateral face (F 2 ) in order to selectively operate through the first vertical lateral face (F 1 ) and/or through the second vertical lateral face (F 2 ) to carry out operations on the first unit ( 12 ) and/or the second unit ( 14 ).

First claim

The invention claimed is:

1. Installation ( 10 ) for the production of containers ( 12 ), particularly bottles, from preforms ( 16 ) of thermoplastic material, said installation ( 10 ) comprising at least:
a first unit ( 12 ) for the thermal conditioning of the preforms ( 16 ) that comprises a first vertical lateral face (F 1 ); and
a second unit ( 14 ) for forming the containers ( 24 ) from said thermally-conditioned preforms ( 16 ) in the first unit ( 12 ), which comprises a second vertical lateral face (F 2 );
characterized in that the installation ( 10 ) comprises at least one robot ( 50 ) that is placed opposite the first vertical lateral face (F 1 ) and opposite the second vertical lateral face (F 2 ) to act selectively through the first vertical lateral face (F 1 ) and/or through the second vertical lateral face (F 2 ) so as to perform operations on the first unit ( 12 ) and/or the second unit ( 14 ).

2. Installation according to claim 1 , wherein said at least one robot ( 50 ) comprises at least first means to help with the operations for changing support means ( 20 ) of the preforms ( 16 ) belonging to the first unit ( 12 ).

3. Installation according to claim 1 , wherein said at least one robot ( 50 ) comprises at least second means ( 70 ) to help with the operations for changing molding means ( 30 ) belonging to the second unit ( 14 ).

4. Installation according to claim 3 , wherein said at least one robot ( 50 ) comprises at least first means to help with the operations for changing support means ( 20 ) of the preforms ( 16 ) belonging to the first unit ( 12 ), and a hinged arm ( 72 ) that is mobile in the space in accordance with a trihedron (X, Y, Z).

5. Installation according to claim 3 , wherein said first means and/or the second means of said at least one robot ( 50 ) are controlled selectively to perform automatically said operations for changing the molding means ( 30 ) and/or said operations for changing the support means ( 20 ) of the preforms.

6. Installation according to claim 1 , wherein the first vertical lateral face (F 1 ) and the second vertical lateral face (F 2 ) extend into the extension of one another.

7. Installation according to claim 1 , wherein the first vertical lateral face (F 1 ) is the external face of one ( 38 ) of the vertical walls of an enclosure ( 32 ) surrounding said first unit ( 12 ) and wherein the first vertical lateral face (F 1 ) comprises closing means ( 52 ) that are mounted to move between a closed position and an open position, to clear selectively at least one opening ( 54 ) making possible the action of said at least one robot ( 50 ) on the first unit ( 12 ).

8. Installation according to claim 1 , wherein the second vertical lateral face (F 2 ) is the external face of one ( 40 ) of the vertical walls of an enclosure ( 32 ) surrounding said second unit ( 14 ) and wherein the second vertical lateral face (F 2 ) comprises closing means ( 56 ) that are mounted to move between a closed position and an open position to clear selectively at least one opening ( 58 ) making possible the action of said at least one robot ( 50 ) on the second unit ( 14 ).

9. Installation according to claim 7 , wherein the first vertical lateral face (F 1 ) and the second vertical lateral face (F 2 ) extend into the extension of one another, and said at least one robot ( 50 ) is installed in an area ( 60 ) delimited by an enclosure ( 62 ), said enclosure ( 62 ) comprising at least said walls ( 38 , 40 ) that comprise respectively the first vertical lateral face (F 1 ) and the second vertical lateral face (F 2 ).

10. Installation according to claim 1 , wherein said at least one robot ( 50 ) is able to be moved opposite the first vertical lateral face (F 1 ) and/or the second vertical lateral face (F 2 ).
